1. Organization, Presentation and Significant Events

GSI Group Inc. (GSIG) and its subsidiaries (collectively the Company) designs, develops, manufactures and sells photonics-based solutions (consisting of lasers, laser systems and
electro-optical components), precision motion devices, associated precision motion control technology and systems. The Companys customers incorporate its technology into their products or manufacturing processes, for a wide range of
applications in a variety of markets, including: industrial, scientific, electronics, semiconductor, medical and aerospace. The Company operates in three segments: Precision Technology, Semiconductor Systems, and Excel. The Excel segment was
established in August 2008 following the Companys acquisition of Excel Technology, Inc. (Excel), a designer, manufacturer and marketer of photonics-based solutions. The Companys principal markets are in North America, Europe,
Japan and Asia-Pacific. The Company exists under the laws of New Brunswick, Canada.

Chapter 11 Bankruptcy Filing

On November 20, 2009 (the Petition Date), GSIG and two of its wholly-owned United States
subsidiaries, GSI Group Corporation (GSI US) and MES International, Inc. (MES and, collectively with GSIG and GSI US, the Debtors), filed voluntary petitions for relief (the Chapter 11 Petitions)
under Chapter 11 of the United States Bankruptcy Code (the Bankruptcy Code) in the United States Bankruptcy Court for the District of Delaware (the Bankruptcy Court) (the Chapter 11 Cases).

Following the Petition Date, the Debtors continued to operate their business as debtors-in-possession under the jurisdiction
of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

On May 24, 2010, the Debtors filed with the Bankruptcy Court a modified joint Chapter 11 plan of reorganization for the Debtors, which was further supplemented on May 27, 2010 (as supplemented,
the Final Chapter 11 Plan). On May 27, 2010, the Bankruptcy Court entered an order confirming and approving the Final Chapter 11 Plan and the plan documents.

On July 23, 2010 (the Effective Date) the Debtors consummated their reorganization through a series of transactions contemplated by the Final Chapter 11 Plan, and the Final Chapter 11
Plan became effective pursuant to its terms. Refer to Note 15 to Consolidated Financial Statements for additional information concerning the Chapter 11 Cases including a description of material agreements the Company entered into on the Effective
Date pursuant to the terms of the Final Chapter 11 Plan.

Listing of Common Shares

Prior to November 4, 2009, the Companys common shares were traded on the NASDAQ Global Select Market under the symbol
GSIG. From November 5, 2009 through November 19, 2009, the Companys common shares were quoted on Pink OTC Markets, Inc., under the trading symbol GSIG. Following the Companys filing of the Chapter 11
Petitions on November 20, 2009, its common shares were quoted on Pink OTC Markets, Inc. under the trading symbol GSIGQ. Following the Companys emergence from bankruptcy on July 23, 2010, its common shares have been quoted
on Pink OTC Markets Inc., under the trading symbol LASR.PK.

Going Concern

On November 20, 2009, GSIG, together with two of its wholly-owned United States subsidiaries, voluntarily filed petitions for relief
under Chapter 11 of the United States Bankruptcy Code. Under the Bankruptcy Code, the Companys status as a bankruptcy debtor automatically accelerated the payment of the debt arising under the $210.0 million of 11% unsecured senior notes due
2013 (the 2008 Senior Notes). Accordingly, this debt has been classified as part of liabilities subject to compromise as of July 2, 2010 and December 31, 2009 in the Companys accompanying consolidated balance sheets.
Operating in bankruptcy imposed significant risks and uncertainties on the Companys business.

However, the Company
emerged from bankruptcy on July 23, 2010 and, in connection therewith, completed a rights offering (the Rights Offering) pursuant to which it sold common shares for approximately $64.9 million in cash proceeds (the Cash
Proceeds). The proceeds from the Rights Offering were used to pay down a portion of the obligations due with respect to the 2008 Senior Notes. The remaining obligations due with respect to the 2008 Senior Notes for unpaid principal and accrued
interest were satisfied through the issuance of the Companys common shares, the payment of cash and the issuance of the new 12.25% Senior Secured PIK Election Notes (the New Notes) which mature in July 2014. As a result of the
Companys emergence from bankruptcy and the associated restructuring of its debt obligations, the Company believes it has sufficient liquidity to fund its operations through at least July 2011.

2. Bankruptcy Disclosures

As discussed in Note 1 to Consolidated Financial Statements, GSIG and two of its United States subsidiaries filed voluntary petitions for
relief under Chapter 11 of the Bankruptcy Code. On May 27, 2010, the Bankruptcy Court entered an order confirming and approving the Final Chapter 11 Plan for the Debtors and the Final Chapter 11 Plan became effective and the transactions
contemplated under the Final Chapter 11 Plan were consummated on July 23, 2010. Presented below are condensed combined financial statements of the Debtors and information concerning liabilities subject to compromise under the Final Chapter 11
Plan, pre-petition professional fees and reorganization items.

The Company has prepared the accompanying consolidated
financial statements in accordance with Accounting Standard Codification (ASC) 852, Reorganizations and on a going-concern basis, which assumes continuity of operations, realization of assets and satisfaction of liabilities
in the ordinary course of business.

ASC 852 requires that the financial statements for periods subsequent to a Chapter 11
filing separate transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, all transactions (including, but not limited to, all professional fees, realized gains and losses
and provisions for losses) directly associated with the reorganization and restructuring of the businesses are reported separately in the financial statements. All such costs are reported in reorganization items in the accompanying consolidated
statements of operations for the three and six months ended July 2, 2010.

Condensed Combined Financial Statements

Since the consolidated financial statements of the Company include entities not in Chapter 11 reorganization
proceedings, the following presents condensed combined financial information of the entities in Chapter 11 reorganization proceedings. The condensed combined financial information has been prepared, in all material aspects, on the same basis as the
consolidated financial statements of the Company.

Basis of Presentation

The financial statements contained within this note represent the condensed combined financial statements for the Debtors only. The
Companys non-Debtor subsidiaries are treated as non-consolidated subsidiaries in these financial statements and as such their net income (loss) is included as Equity income (loss) from non-Debtor subsidiaries, net of tax in the
statement of operations and their net assets are included as Investments in non-Debtor subsidiaries in the balance sheets.

Intercompany Transactions

Intercompany transactions between Debtors have
been eliminated in the financial statements contained herein. Intercompany transactions with the Debtors non-Debtor subsidiaries have not been eliminated in the financial statements and are reflected as Liabilities to non-Debtor
subsidiaries, net.

Liabilities Subject to Compromise

As a result of the Chapter 11 filing, the payment of pre-petition indebtedness may be subject to compromise or other treatment under the
Final Chapter 11 Plan as described in more detail below. Generally, actions to enforce or otherwise affect payment of pre-petition liabilities are stayed. Although pre-petition claims are generally stayed, at a hearing held on November 24,
2009, the Bankruptcy Court approved the Debtors first day motions generally designed to stabilize the Debtors operations and cover, among other things, human capital obligations, supplier relations, customer relations,
business operations, tax matters, cash management, utilities, case management and retention of professionals.

The
Companys undisputed post-petition claims are being paid in the ordinary course of business. In addition, the Debtors may reject pre-petition executory contracts and unexpired leases with respect to the Debtors operations, with the
approval of the Bankruptcy Court. Damages resulting from rejection of executory contracts and unexpired leases are treated as general unsecured claims and are classified as liabilities subject to compromise upon rejection. On January 20, 2010,
the Bankruptcy Court established February 24, 2010 as the bar date for non-governmental units and May 19, 2010 as the bar date for governmental units. The bar date is the date by which claims against the Debtors arising prior to the
Debtors Chapter 11 filings must be filed if the claimants wish to receive any distribution in the Chapter 11 Cases. On January 25, 2010, the Debtors commenced notification, including publication, to all known actual and potential
creditors informing them of the bar date and the required procedures with respect to the filing of proofs of claim with the Bankruptcy Court.

Liabilities subject to compromise consisted of the following (in thousands):

3. Summary of Significant Accounting Policies

Basis of Presentation

These consolidated financial statements have been prepared by the Company in U.S. dollars and in accordance with U.S. generally accepted accounting principles, applied on a consistent basis.

The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the
United States Securities and Exchange Commission (SEC), and the instructions to Form 10-Q and the provisions of Regulation S-X pertaining to interim financial statements. Accordingly, certain information and footnote disclosures normally
included in the financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted pursuant to such rules and regulations. The consolidated
financial statements and notes included in this report should be read in conjunction with the financial statements and notes included in the Companys Annual Report on Form 10-K for the fiscal year ended December 31, 2009, filed with the
SEC.

The interim consolidated financial statements include the accounts of the Company. Intercompany transactions and
balances have been eliminated. In the opinion of management, all adjustments and accruals necessary for a fair presentation have been made and include only normal recurring adjustments and accruals. The results for interim periods are not
necessarily indicative of results to be expected for the year or for any future periods.

Basis of Consolidation

The consolidated financial statements include the accounts of GSI Group Inc. and its wholly owned subsidiaries. The
accounts include a 50% owned joint venture, Excel Laser Technology Private Limited (Excel SouthAsia JV), since it is a variable interest entity and the Company is the primary beneficiary of the joint venture. The accompanying
consolidated financial statements of the Company include the assets, liabilities, revenue, and expenses of Excel SouthAsia JV over which the Company exercises control. The Company records noncontrolling interest in its consolidated statements of
operations for the ownership interest of the minority owners of Excel SouthAsia JV. Financial information related to the joint venture is not considered material to the consolidated financial statements. Intercompany accounts and transactions have
been eliminated.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation in the consolidated financial statements
and notes thereto as of and for the three and six months ended July 2, 2010. The Company reclassified $1.1 million from inventories, prepaid expenses and other current assets, and accrued expenses to deferred cost of goods sold as of
December 31, 2009. These reclassifications had no effect on the Companys previously reported results of operations, financial position and cash flows.

Use of Estimates

The preparation of financial statements in
conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the
financial statements and the reported amounts of sales and expenses during the reporting periods. On an ongoing basis, the Company evaluates its estimates, assumptions and judgments, including those related to revenue recognition; allowance for
doubtful accounts; inventory costing and reserves; the assessment of warranty reserves; the valuation of goodwill, intangible assets and other long-lived assets; accounting for business combinations; share-based payments; employee benefit plans;
accounting for restructuring activities; accounting for income taxes and related valuation allowances; and, accounting for loss contingencies. Actual results could differ significantly from those estimates.

Cash and Cash Equivalents

Cash equivalents consist principally of money market funds invested in U.S. Treasury Securities and repurchase agreements of U.S. Treasury Securities that have original maturities of 90 days or less. The
Company does not believe it is exposed to any significant credit risk related to its cash equivalents.

Financial
Instruments and Fair Value Measurements

Financial instruments with remaining maturities within one year from the
balance sheet date are classified as current. Financial instruments with remaining maturities more than one year from the balance sheet date are classified as long-term.

Long-Term Investments

As of July 2, 2010, the Company had liquidated
all of its previously held auction rate securities. As of December 31, 2009, the Company held auction rate securities, recorded at a fair value of $11.3 million, and with a par value of $13.0 million. These auction rate notes were student loans
backed by the federal government and were privately insured. From April 3, 2009 through July 3, 2009, the Company recorded $0.2 million of other comprehensive income attributable to the change in unrealized gains relating to assets still
held at July 3, 2009. From January 1, 2009 through July 3, 2009, the Company recorded $0.8 million of other comprehensive income attributable to the change in unrealized gains relating to assets still held at July 3, 2009.

During the three months ended July 2, 2010, the Company sold $10.0 million in par value of its auction rate securities
valued at $8.0 million for $8.7 million in proceeds, which resulted in the recognition of realized gains of $0.7 million related to the sale of these securities. During the three months ended July 3, 2009, the Company sold $14.9 million in
par value of its auction rate securities valued at $11.3 million for $13.0 million in proceeds, which resulted in the recognition of realized gains of approximately $1.7 million related to the sale of these securities. During the six months ended
July 2, 2010, the Company sold $13.0 million in par value of its auction rate securities valued at $10.4 million for $11.4 million in proceeds, which resulted in the recognition of realized gains of $1.0 million related to the sale of these
securities. During the six months ended July 3, 2009, the Company sold $15.2 million in par value of its auction rate securities valued at $11.5 million for $13.3 million in proceeds, which resulted in the recognition of realized gains of
approximately $1.8 million related to the sale of these securities. The gains realized upon the sale of the auction rate securities are recorded in other income (expense), net in the accompanying consolidated statements of operations for the three
and six months ended July 2, 2010 and July 3, 2009. The Company determines the cost of a security sold and the amount to be reclassified out of accumulated other comprehensive income (loss) into earnings based on the specific
identification method. During the three and six months ended July 2, 2010, the Company reclassified $0.4 million and $0.6 million, respectively, out of accumulated other comprehensive income (loss) into earnings related to the sale of the
Companys auction rate securities. During the three and six months ended July 3, 2009, the Company reclassified $0.4 million out of accumulated other comprehensive income (loss) into earnings related to the sale of the Companys
auction rate securities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

At July 2, 2010 and December 31, 2009, the Company had a 25.1% equity
investment in a privately held company located in the United Kingdom, valued at $1.9 million and $1.4 million at July 2, 2010 and December 31, 2009, respectively, and included in other assets in the accompanying consolidated balance
sheets. The Company uses the equity method to record the results of this entity. In relation to this investment, the Company recognized income of $0.4 million and $0.2 million for the three months ended July 2, 2010 and July 3, 2009,
respectively, which are included in other income (expense), net in the accompanying consolidated statements of operations. In relation to this investment, the Company recognized income of $0.6 million and $0.2 million for the six months ended
July 2, 2010 and July 3, 2009, respectively, which are included in other income (expense), net in the accompanying consolidated statements of operations.

Fair Value Measurements

On January 1, 2008, the Company adopted ASC
820, Fair Value Measurements and Disclosures with no impact to its consolidated results and financial position. ASC 820 defines fair value, establishes a framework for measuring fair value, and enhances disclosures about fair value
measurements. Fair value is defined as the price that would be received for an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. Valuation techniques must maximize the use of
observable inputs and minimize the use of unobservable inputs.

ASC 820 establishes a fair value hierarchy based on three
levels of inputs, of which the first two are considered observable and the third is considered unobservable:



| |  |  | Level 1. Quoted prices for identical assets or liabilities in active markets which the Company can access.
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | Level 2. Observable inputs other than those described in Level 1.
| | - |  | -----------------------------------------------------------------



| |  |  | Level 3. Unobservable inputs.
| | - |  | -----------------------------

On January 1, 2009, the Company implemented the guidance in ASC 820 related to all nonrecurring fair value measurements of nonfinancial assets and nonfinancial liabilities. However, no significant
nonrecurring fair value measurements were conducted during the three and six months ended July 2, 2010 or July 3, 2009 other than the annual impairment test for goodwill and indefinite-lived intangible assets, for which no impairment loss
was recognized.

The following table summarizes the Companys assets and liabilities, as of July 2, 2010, that are
measured at fair value on a recurring basis (in thousands):

See Note 6 to Consolidated Financial Statements for discussion of the estimated fair value of the
Companys 2008 Senior Notes.

Accounts Receivable and Allowance

Trade accounts receivable are recorded at the invoiced amount. The Company generally does not require collateral for trade accounts
receivable. The Company maintains an allowance for doubtful accounts. The allowance for doubtful accounts is based on the Companys best estimate of the amount of probable credit losses resulting from the inability of the Companys
customers to make required payments. The Company determines the allowance based on a variety of factors including the age of amounts outstanding relative to their contractual due date, specific customer factors, and other known risks and economic
trends in industries. Charges booked to the allowance for doubtful accounts are recorded as selling, general and administrative expenses, and are recorded in the period that they are determined to be uncollectible.

Inventories

Inventories, which include materials and conversion costs, are stated at the lower of cost or market, using the first-in, first-out method. Market is defined as replacement cost for raw materials and net
realizable value for other inventories. Demo inventory is recorded at the lower of cost or its net realizable value.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, adjusted for any impairment, less accumulated depreciation. The Company uses the straight-line method to calculate the depreciation of its fixed assets
over their estimated useful lives. Estimated useful lives for buildings and improvements range from 3 to 60 years and for machinery and equipment from 1 to 13 years. Leasehold improvements are amortized over the lesser of their useful lives or lease
terms, including any renewal period options that are expected to be exercised. Repairs and maintenance are expensed as incurred.

The Company undertakes a review of its property, plant and equipment carrying values whenever events or circumstances indicate that the carrying amounts may not be recoverable. The Company relies on the
guidance included in ASC 360-10-35-15, Impairment or Disposal of Long-Lived Assets when conducting these reviews. No impairment charges related to property, plant and equipment were recorded during the three and six months ended
July 2, 2010 or July 3, 2009.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price in a business combination over the fair value of the acquired tangible and intangible
net assets. In connection with its acquisition of Excel, the Company acquired certain trade names that are classified as intangible assets with indefinite lives. Goodwill and indefinite-lived intangibles are not amortized but they are required
to be assessed for impairment at least annually to ensure their current fair values exceed their carrying values.

The Company
also has certain intangible assets that are amortized over their estimated useful lives. These definite-lived intangible assets were acquired in connection with the Companys historic business combinations. The Companys most
significant intangible assets are acquired technology, customer relationships, and trademarks and trade names. All definite-lived intangible assets are amortized over the periods in which their economic benefits are expected to be realized. In
addition to the Companys review of the carrying values of intangible assets, the Company also reviews the useful life assumptions, including the classification of certain intangible assets as indefinite-lived, on a periodic basis
to determine if changes in circumstances warrant revisions to them.

The Companys product lines generally correspond with its reporting units which is
the level at which the Company evaluates its goodwill, intangible assets and other long-lived assets for impairment. All of the Companys goodwill and intangible assets reside in the Precision Technology and Excel segments.

Impairment Charges

Impairment analyses of goodwill and indefinite-lived intangible assets are conducted in accordance with ASC 350, IntangiblesGoodwill and Other. The Company tests its goodwill balances
annually in the beginning of the second quarter or more frequently if indicators are present or changes in circumstances suggest that impairment may exist. In performing the test, the Company utilizes the two-step approach which requires a
comparison of the carrying value of each of the Companys reporting units to the fair value of these reporting units. If the carrying value of a reporting unit exceeds its fair value, the Company calculates the implied fair value of the
reporting units goodwill and compares it to the goodwills carrying value. If the carrying value of goodwill exceeds its implied fair value, an impairment charge is recorded for the difference. The fair value of a reporting unit is
estimated based on a discounted cash flow (DCF) approach. The DCF approach requires that the Company forecast future cash flows for each of the reporting units and discount the cash flow streams based on a weighted average cost of
capital (WACC) that is derived, in part, from comparable companies within similar industries. The DCF calculations also include a terminal value calculation that is based upon an expected long-term growth rate for the applicable
reporting unit. The carrying values of each reporting unit include assets and liabilities which relate to the reporting units operations. Additionally, reporting units that benefit from corporate assets or liabilities are allocated a portion
of those corporate assets and liabilities on a systematic, proportional basis.

As mentioned above, the Companys
indefinite-lived intangible assets represent trade names that were acquired in the August 2008 Excel acquisition. The Company assesses these indefinite-lived intangible assets for impairment on an annual basis as of the beginning of the second
quarter, and more frequently if indicators are present or changes in circumstances suggest that impairment may exist. The Company will also periodically reassess these indefinite-lived intangible assets continuing classification as
indefinite-lived. The fair values of the Companys indefinite-lived intangible assets are determined using the relief from royalty method, based on forecasted revenues. If the fair value of an intangible asset is less than its carrying value,
an impairment charge is recorded to reflect the difference between the carrying value and the fair value of the impaired asset.

Intangible assets with definite lives are amortized over their estimated useful lives. The carrying amounts of definite-lived intangible
assets and other long-lived assets are reviewed for impairment whenever changes in events or circumstances indicate their carrying values may not be recoverable. The impairment analyses are conducted in accordance with ASC 360-10-35-15. The
recoverability of carrying value is determined by comparison of the reporting units carrying value to its future undiscounted cash flows. When this test indicates the potential for impairment, a fair value assessment is performed.

Once impairment is determined and measured, an impairment charge is recorded to reflect the difference between the carrying value and the
fair value of the impaired asset. In addition to evaluating the impairment of goodwill and intangible assets, the Company also assesses its other long-lived assets for impairment. This process is discussed above under Property, plant and
equipment.

The most recent annual goodwill and indefinite-lived intangible asset impairment test was performed as of
the beginning of the second quarter of 2010 noting no impairment. No impairment charges were recorded during the three and six months ended July 2, 2010 or July 3, 2009.

Revenue Recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, risk of loss has passed to the customer and collection of the
resulting receivable is reasonably assured. Revenue recognition requires judgment and estimates, which may affect the amount and timing of revenue recognized in any given period.

The Company follows the provisions of ASC 605-25, Multiple Element Arrangements for all multiple element arrangements. Under
ASC 605-25, the Company assesses whether the deliverables specified in a multiple element arrangement should be treated as separate units of accounting for revenue recognition purposes and whether objective and reliable evidence of fair value exists
for these separate units of accounting. The Company applies the residual method when objective and reliable evidence of fair value exists for all of the undelivered elements in a multiple element arrangement. When objective and reliable evidence of
fair value does not exist for all of the undelivered elements in a multiple element

arrangement, the Company recognizes revenue under the multiple units shipped methodology, whereby revenue is recognized in each period based upon the lowest common percentage of the products
shipped in the period. This approximates a proportional performance model of revenue recognition. This generally results in a partial deferral of revenue to a later reporting period. No revenue is recognized unless one or more units of each product
has been delivered.

Although certain of the Companys products contain operating and application software, the Company
has determined the software element is incidental in accordance with ASC 985-605, Software Revenue Recognition.

The Company determines the unit of accounting for certain transactions based on the guidance in ASC 985-605. In particular, multiple
purchase orders may be deemed to be interrelated and considered to constitute a multiple element arrangement for accounting purposes.

Semiconductor Systems transactions are generally multiple element arrangements which may include hardware, software, installation, training, an initial standard warranty, and optional extended warranty
arrangements. The Company generally designs, markets and sells these products as standard configurations. For those standard configurations where acceptance criteria, if any, exist and are demonstrated prior to shipment, revenue is recorded at the
time of shipment. For those cases where acceptance criteria cannot be demonstrated prior to shipment of a product or if a significant amount of fees are due upon acceptance, the Company recognizes revenue upon customer acceptance. Acceptance is
generally required for sales of Semiconductor Systems segment products to Japanese customers, sales of New Products, which are considered by the Company, for purposes of revenue recognition determination, to be either (a) a product
that is newly released to all customers, including a product which may have been existing previously, but which has been substantially upgraded with respect to its features or functionality; or, (b) the sale of an existing product to a customer
who has not previously purchased that product. The Company follows a set of predetermined criteria when changing the classification of a New Product to a standard configuration whereby acceptance criteria are considered to be demonstrated at the
time of shipment.

Precision Technology and Excel revenue transactions include both single element and multiple element
transactions. Multiple element transactions may include two or more products and occasionally also contain installation, training or preventative maintenance plans. Revenue is generally recognized under the multiple units shipped methodology
described above.

The Companys Semiconductor Systems segment also sells spare parts and consumable items, which are not
subject to acceptance criteria. Revenue for these spare parts and consumable items is generally recognized under the multiple units shipped methodology described above.

Installation is generally a routine process that occurs within a short period of time from delivery and the Company has concluded that this obligation is inconsequential and perfunctory. As such, for
transactions that include installation, and for which customer acceptance has not been deemed necessary in order to record the revenue, the cost of installation is accrued at the time product revenue is recorded and no related revenue is deferred.
Historically, the costs of installation have not been significant.

The initial standard warranty for product sales is
accounted for under the provisions of ASC 450, Contingencies as the Company has the ability to ascertain the probable likelihood of the liability, and can estimate the amount of the liability. A provision for the estimated cost related
to warranty is recorded to cost of goods sold at the time revenue is recognized. The Companys estimate of costs to service the warranty obligations are based on historical experience and expectations of future conditions. To the extent the
Company experiences increased warranty claims or increased costs associated with servicing those claims, revisions to the estimated warranty liability are recorded as increases or decreases to the accrual at that time, with an offsetting entry
recorded to cost of goods sold.

The Company also sells optional extended warranty services, and preventative maintenance
contracts, at the time of their product purchase. The Company accounts for these agreements in accordance with provisions of ASC 605-20-25-3, Separately Priced Extended Warranty and Product Maintenance Contracts under which it recognizes
the separately priced extended warranty and preventative maintenance fees over the associated period.

The Company, at the
request of its customers, may at times perform professional services for its customers, generally for the maintenance and repairs of products previously sold to those customers. These services are usually in the form of time and materials based
contracts which are short in their duration. Revenue for time and material services is recorded at the completion of services requested under a customers purchase order. Customers may, at times subsequent to the initial product sale, purchase
a service contract whereby services, including preventative maintenance plans, are provided over a defined period, generally one year. Revenue for such service contracts are recorded ratably over the period of the contract.

The Company typically negotiates trade discounts and agreed terms in advance of order
acceptance and records any such items as a reduction of revenue. The Companys revenue recognition policy allows for revenue to be recognized under arrangements where the payment terms are 180 days or less, presuming all other revenue
recognition criteria have been met. From time to time, based on the Companys review of customer creditworthiness and other factors, the Company may provide its customers with payment terms that exceed 180 days. To the extent all other revenue
recognition criteria have been met, the Company recognizes revenue for these extended payment arrangements as the payments become due.

The Company has significant deferred revenue included in its accompanying consolidated balance sheets, with balances (including both current and long-term amounts) of $16.4 million and $55.8 million as of
July 2, 2010 and December 31, 2009, respectively. A significant majority of these amounts relate to arrangements whereby the entire arrangement has been accounted for as deferred revenue, as there is no fair value for one or more of the
undelivered elements. Upon the final delivery of the undelivered element(s) of the arrangement, the revenue will be recorded for that arrangement. To a much lesser extent, the deferred revenue balances relate to either: (a) the unrecognized
portion of a multiple element arrangements that is being recognized into revenue over a ratable basis as associated services are performed; (b) arrangements not currently recognizable due to the arrangement not being fixed and determinable at
its inception; (c) the future amortization to revenue of extended warranty contracts and preventative maintenance plans; (d) revenue deferrals for product shipments with FOB destination shipping terms; and (e) deposits from customers
against future orders. The classification of deferred revenue, and deferred cost of goods sold, is based on the Companys expectations relative to when the revenue will be recognized, based on facts known to the Company as of the date its
financial statements are released.

Deferred Cost of Goods Sold

The Company defers the corresponding direct costs associated with the deferred revenue. These deferred costs have been recorded as
deferred cost of goods sold in the accompanying consolidated balance sheets and are reflected in the consolidated statements of operations as cost of goods sold when the related revenue is expected to be recognized. These costs represent the direct
and incremental costs that are attributable to the product whose revenue is being deferred.

Research and Development
and Engineering Costs

Internal costs relating to research and development and engineering costs incurred for new
products and enhancements to existing products are expensed as incurred.

Product Warranty

The Company generally warrants its products for material and labor to repair and service the system. The standard warranty is generally a
period of up to 12 months, with the exception of two product lines, DRC Encoders and JK Lasers, both being product lines that are included in the Precision Technology segment, and which have a warranty period of 24 months. The accounting for
warranty provisions is discussed above in Revenue Recognition.

Share-Based Compensation

The Company has stock-based compensation plans which are more fully described in Note 8 to Consolidated Financial Statements. The Company
recognizes the fair value of all share-based payments to employees as expense.

Shipping & Handling Costs

Shipping and handling costs are recorded in cost of goods sold.

Advertising Costs

Advertising costs are expensed as incurred.

Foreign Currency Translation

The financial statements of the Company and its subsidiaries outside the United States have been translated into
United States dollars in accordance with ASC 830, Foreign Currency Matters. Assets and liabilities of foreign operations are translated from foreign currencies into United States dollars at the exchange rates in effect on the balance
sheet date.

Sales and expenses are translated at the average exchange rate in effect for the period. Accordingly, gains and losses resulting from translating foreign currency financial statements are
reported as a separate component of other comprehensive income (loss) in stockholders equity. Foreign currency transaction gains and losses are included in net income (loss) in the accompanying consolidated statements of operations. These
amounts arose primarily from transactions denominated in currencies other than the functional currency.

Restructuring,
Restatement Related Costs and Other

In accounting for its restructuring activities, the Company follows the provisions
of ASC 420, Exit or Disposal Cost Obligations. In accounting for these obligations, the Company makes assumptions related to the amounts of employee severance, benefits, and related costs and to the time period over which facilities will
remain vacant, sublease terms, sublease rates and discount rates. Estimates and assumptions are based on the best information available at the time the obligation has arisen. These estimates are reviewed and revised as facts and circumstances
dictate; changes in these estimates could have a material effect on the amount previously expensed against the Companys earnings, and currently accrued on the Companys consolidated balance sheet.

The costs incurred related to third parties, including auditors, attorneys, forensic accountants, and other advisors for services
performed in connection with the restatement of the Companys previously issued financial statements as reported in its Annual Report on Form 10-K for the year-ended December 31, 2008 and its Quarterly Report on Form 10-Q for the quarter
ended September 26, 2008, including, the SEC investigation, certain shareholder actions and the internal Foreign Corrupt Practices Act (FCPA) investigation have been included within the Companys restructuring, restatement
related costs and other charges in the accompanying consolidated statements of operations.

Pre-Petition Professional
Fees

Pre-petition professional fees represent costs incurred prior to the Companys bankruptcy filing related to
the financial and legal advisors retained by the Company to assist in the analysis of debt restructuring alternatives, as well as costs incurred by the Company related to financial and legal advisors retained by the noteholders pursuant to certain
binding agreements between the two parties.

Net Income (Loss) Per Common Share

Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares
outstanding during the period. For diluted net income per common share, the denominator also includes any dilutive outstanding stock options and restricted stock determined using the treasury stock method. Potentially dilutive securities are
excluded from the diluted earnings per share computation to the extent they are anti-dilutive. Common and common share equivalent disclosures are (in thousands):

Accounting for Income Taxes

The liability method is used to account for income taxes. Deferred tax assets and liabilities are recognized for the
future tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which
the differences are expected to be recovered or settled. A valuation allowance is established to reduce the deferred tax assets if it is more likely than not that some or all of the related tax benefits will not be realized in the
future.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Fair Value
Measurements

On January 1, 2010, the Company adopted ASU 2010-06, Improving Disclosures about Fair Value
Measurement, which requires interim disclosures regarding significant transfers in and out of Level 1 and Level 2 fair value measurements. Additionally, this ASU requires disclosure for each class of assets and liabilities and disclosures
about the valuation techniques and inputs used to measure fair value for both recurring and non-recurring fair value measurements. These disclosures are required for fair value measurements that fall in either Level 2 or Level 3. Further, the ASU
requires separate presentation of purchases, sales, issuances and settlements in the Level 3 rollforward of the fair value measurements. The Company adopted the interim disclosure requirements under this ASU on January 1, 2010, with the
exception of the separate presentation in the Level 3 activity rollforward, which is not effective until fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. The Companys adoption of ASU
2010-06 did not have an impact on the Companys financial position, results of operations or cash flows.

Subsequent
Events

On April 4, 2009, the Company adopted ASC 855, Subsequent Events, which establishes general
standards of accounting for, and disclosure of, events that occur after the balance sheet date but before financial statements are issued or are available to be issued. ASC 855 originally required all companies to disclose the date through which
subsequent events have been evaluated for disclosure and recognition. In February 2010, the FASB issued an amendment to ASC 855 (ASU 2010-09, Subsequent Events-Amendments to Certain Recognition and Disclosure Requirements), which removed
the requirement for an SEC filer to disclose the date through which subsequent events have been evaluated for disclosure and

recognition in issued and revised financial statements. ASU 2010-09 was effective for the Company immediately. The Companys adoption of ASC 855 did not have an impact on the Companys
financial position, results of operations or cash flows. The Company adopted ASU 2010-09 in February 2010, but its adoption did not have an impact on its financial position, results of operations or cash flows.

Recently Issued Accounting Pronouncements

Revenue Recognition

In September 2009, the FASB issued ASU 2009-13,
Multiple-Deliverable Revenue Arrangements. ASU 2009-13 amends existing revenue recognition accounting pronouncements that are currently within the scope of ASC 605-25, Multiple Element Arrangements. ASU 2009-13 provides two
significant changes to the existing multiple element revenue recognition guidance. First, this guidance removes the requirement to have objective and reliable evidence of fair value for undelivered elements in an arrangement and will result in more
deliverables being treated as separate units of accounting. The second change modifies the manner in which the transaction consideration is allocated across the separately identified deliverables. These changes may result in entities recognizing
more revenue up-front, and entities will no longer be able to apply the residual method and defer the fair value of undelivered elements. Upon adoption, each separate unit of accounting must have an estimated selling price, which can be based on
managements estimate when there is no other means to determine the fair value of that undelivered item, and the arrangement consideration is allocated based on the elements relative selling price. This accounting guidance is effective no
later than fiscal years beginning on or after June 15, 2010 but may be early adopted as of the first quarter of an entitys fiscal year. Entities may elect to adopt this accounting guidance either through prospective application to all
revenue arrangements entered into or materially modified after the date of adoption or through a retrospective application to all revenue arrangements for all periods presented in the financial statements. The Company is currently evaluating the
impact that its adoption of ASU 2009-13 will have on its financial position, results of operations and cash flows. The Company anticipates that it will adopt ASU 2009-13 effective January 1, 2011 on a prospective basis.

4. Goodwill and Intangible Assets

Goodwill

Goodwill is recorded when the consideration for an
acquisition exceeds the fair value of net tangible and identifiable intangible assets acquired. There were no changes in the carrying amount of goodwill during the six months ended July 2, 2010. Goodwill by reportable segment is as follows (in
thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

6. Debt

On August 20, 2008 (the Closing Date), the Company issued to various investors $210.0 million of unsecured senior notes pursuant to the terms of an indenture (the 2008 Senior Note
Indenture), along with detachable warrants (the Warrants) for the purchase of 5,882,520 of the Companys common shares, for collective net proceeds to the Company of $203.5 million. The proceeds were used to fund a portion of
the Companys acquisition of Excel, and the 2008 Senior Notes carry a fixed interest rate of 11.0%. The Warrants were net exercised by the holders in October 2008, in exchange for 5,858,495 common shares of the Company. The Company ascribed a
fair value to the Warrants in the amount of $26.3 million as of the Closing Date and recognized this amount as debt discount that was being amortized over the term of the 2008 Senior Notes. The fair value was based upon the Black-Scholes option
pricing model, assuming a risk-free interest rate of 3.0%, an expected term of 5.0 years, a volatility rate of 85.0% and a 0.0% dividend yield. In addition, the Company incurred $6.5 million in issuance fees.

The 2008 Senior Notes pay interest semi-annually on February 15thand August 15thand mature in August 2013. Following the first anniversary of the
Closing Date, the Company had the right to redeem up to 50% of the 2008 Senior Notes at par without penalty. Following the third anniversary of the Closing Date, the Company had the right to redeem up to 100% of the 2008 Senior Notes at par without
penalty. The 2008 Senior Note Indenture contained covenants that restricted the Companys ability to incur additional indebtedness, pay dividends, create liens, make investments, sell assets, repurchase securities, or engage in specified
transactions with affiliates.

As discussed in Note 1 to Consolidated Financial Statements, GSIG and two of its wholly-owned
United States subsidiaries filed for bankruptcy on November 20, 2009. Accordingly, the 2008 Senior Notes are classified as a liability subject to compromise in accordance with ASC 852 in the Companys accompanying consolidated balance
sheets as of July 2, 2010 and December 31, 2009.

In accordance with the reclassification of the 2008 Senior Notes
after the November 20, 2009 bankruptcy filing to liabilities subject to compromise, the Company recorded write-offs related to the remaining unamortized portion of the discount attributable to the Warrants and deferred debt financing costs in
order to record the 2008 Senior Notes at the expected amount of the allowed claims. The aggregate amount of the write-off related to the remaining unamortized portion of the discount attributable to the Warrants totaled $21.4 million, while the
write-off related to the remaining unamortized portion of the deferred debt financing costs totaled $4.9 million. Both the write-off related to the remaining unamortized portion of the debt discount attributable to the Warrants and the write-off
related to the deferred debt financing costs were recorded as reorganization items during the quarter ended December 31, 2009. For the three months ended July 2, 2010 and July 3, 2009, the total amount recorded to interest expense,
including accretion of the debt discount attributable to the Warrants and amortization of the debt issuance costs during 2009, was $5.7 million and $7.1 million, respectively. For the six months ended July 2, 2010 and July 3, 2009, the
total amount recorded to interest expense, including accretion of the debt discount attributable to the Warrants and amortization of the debt issuance costs during 2009, was $11.5 million and $14.2 million, respectively.

During the third quarter of 2008, the Company failed to timely file its annual and quarterly reports. Pursuant to a Registration Rights
Agreement (the RRA) with the Warrant holders, the Company notified the Warrant holders that it was indefinitely suspending its registration statement on Form S-3. Under the RRA, monetary penalties accrue and are payable to the
Warrant holders for failure to maintain an effective registration statement, subject to certain terms and conditions more specifically set forth therein. The Company incurred penalties under the RRA beginning in the fourth quarter of 2008 through
the date of the Companys filing for Chapter 11 bankruptcy protection on November 20, 2009. The Company had accrued the maximum penalty due under the RRA of $3.8 million, including $0.9 million and $1.9 million during the three and six
months ended July 3, 2009, respectively. However, as a result of the Companys filing for Chapter 11 bankruptcy protection on November 20, 2009, the Company reversed the existing balance of the Warrant penalty accrual as part of its
reclassification of the 2008 Senior Notes as liabilities subject to compromise.

Pursuant to the Final Chapter 11 Plan, on
July 23, 2010 upon emergence from bankruptcy, $74.9 million of the 2008 Senior Notes were repaid in cash, $28.1 million were exchanged for approximately 15.6 million common shares, and the remaining 2008 Senior Notes were cancelled and
replaced by $107.0 million in aggregate principal amount of 12.25% Senior Secured PIK Election Notes which mature on July 23, 2014. See Note 15 to Consolidated Financial Statements for information concerning transactions related to the Chapter
11 Cases.

Fair Value of Debt

No public trades of the 2008 Senior Notes occurred during the six months ended July 2, 2010. The Company engaged in ongoing
negotiations regarding the value of the 2008 Senior Notes and an appropriate restructuring plan throughout this time period with the lender group and others. Thus, although the actual value of the 2008 Senior Notes may have varied materially if
trading had taken place, the Company estimates that the fair value of the 2008 Senior Notes as of July 2, 2010 was its associated par value.

7. Stockholders Equity

Capital Stock

The authorized capital of the Company consists of an unlimited number of common shares without nominal or par value. Holders of common
shares are entitled to one vote per share. Holders of common shares are entitled to receive dividends, if and when declared by the Board of Directors, and to share ratably in its assets legally available for distribution to the stockholders in the
event of liquidation. Holders of common shares have no redemption or conversion rights.

Shareholders Rights Plan

At the annual meeting of shareholders held on May 15, 2008, shareholders approved a resolution approving the
continuation, amendment and restatement of the Companys shareholders rights plan.

Prior to the 2008 annual meeting of
shareholders, the Board of Directors of the Company approved an amended and restated shareholder rights plan agreement to be dated May 15, 2008 (the Rights Plan), if approved by shareholders at such meeting. The Rights Plan was
originally approved by the Companys shareholders on May 26, 2005 and its continued existence had to be approved and confirmed by independent shareholders on or before the date of the Companys 2008 annual meeting of shareholders or
the Rights Plan would expire.

The amended and restated shareholder rights plan continues to create a right (which is only
triggered if a person or a control group acquires 20% or more of the Companys issued and outstanding publicly traded common shares) for each shareholder, other than the acquiring person or its associates or affiliates, to acquire additional
common shares of the Company at one-half of the then market price at the time of exercise. The net effect of an exercise is to dilute the prospective acquirers share position, and inhibits a change of control event unless the Rights Plan has
been withdrawn or the buyer makes a bid that is permitted by the terms of the plan.

The Rights Plan is intended to give the
Companys Board of Directors more time and control over any sale process and increase the likelihood of maximizing shareholder value. The Rights Plan was cancelled in connection with the Companys emergence from the Chapter 11 proceedings.
See Note 15 to Consolidated Financial Statements.

Stock Repurchase Plan

In December 2005, the Companys Board of Directors authorized a stock repurchase program providing for the repurchase of up to
$15.0 million in shares of the Companys common shares. In February 2008, the Companys Board of Directors authorized an increase in the stock repurchase program up to a total of $40.0 million. The Company repurchased and retired
772,467 shares, 816,830 shares, and 381,300 shares in 2008, 2007, and 2006, respectively, at an aggregate cost of $6.4 million, $7.8 million, and $3.8 million, respectively. The program was suspended in May 2008 as a result of the Companys
decision to acquire Excel. At July 2, 2010, $21.9 million remains available for future Company purchases under this program. In connection with the Chapter 11 Cases, the stock repurchase program was cancelled. See Note 15 to Consolidated
Financial Statements.

8. Share-Based Compensation

The Company has several share-based compensation plans, including the 2006 Equity Incentive Plan, under which stock-based grants may be issued and several other plans under which no new grants will be
made. The 2006 Equity Incentive Plan provides for grants of various stock-based awards including, but not limited to, stock options, stock appreciation rights and restricted stock. Since 2006, the Company has issued only restricted stock in the form
of time and performance-based grants to senior executives, key employees and directors.

2006 Equity Incentive Plan

On May 15, 2006, shareholders of the Company approved the 2006 Equity Incentive Plan which provides for the sale or grant of various
awards of, or the value of, the Companys common shares including stock options, stock appreciation rights, restricted stock and performance shares and units, performance-based awards, and stock grants, to officers, directors, employees and
certain consultants to the Company. The maximum number of shares of the Companys common shares which may be issued pursuant to the 2006 Equity Incentive Plan is 9,406,000 shares, including a 2,500,000 share increase as approved by the
Companys shareholders at the May 2008 annual meeting, and subject to adjustment in the event of certain corporate events and reduced by the number of shares already issued pursuant to awards under the Companys 1992 and 1995 Equity
Incentive Plans. The plan has a ten-year term. As of July 2, 2010, there were 4,246,784 common shares available for future issuance under this plan. All unvested restricted stock awards and unexercised options to purchase shares of common stock
related to the Companys 2006 Equity Incentive Plan that were outstanding on the date of the Companys emergence from bankruptcy were assumed by the reorganized Company upon emergence, other than those held by the Companys directors
who did not continue as members of the reorganized Companys Board of Directors following emergence. Such assumed restricted stock awards and options will be honored by the Company as if they had originally been granted for the issuance of the
Companys post-emergence common shares. The Companys 2006 Equity Incentive Plan was cancelled upon the Companys emergence from bankruptcy. Accordingly, no shares remain available for future issuance under this plan as of
July 23, 2010. See Note 15 to Consolidated Financial Statements.

The Company recorded compensation expense related to
restricted stock awards issued under the 2006 Equity Incentive Plan totaling $0.4 million in the three month periods ended July 2, 2010 and July 3, 2009, and $1.1 million and $1.3 million in the six month periods ended July 2, 2010
and July 3, 2009, respectively. Approximately ($0.1) million of the compensation expense recognized during the three month period ended July 2, 2010 and approximately $0.2 million of the compensation expense recognized during the six month
period ended July 2, 2010 relates to awards that are accounted for as share-based liabilities under ASC 718. The share-based liabilities relate to the Companys obligations arising from its commitment to issue shares of restricted stock
and common stock to the members of its pre-emergence Board of Directors as compensation for their services provided as members of the Companys Board of Directors. The associated liability is reported within other accrued expenses in the
accompanying consolidated balance sheets as of July 2, 2010 and December 31, 2009. The expense associated with the Companys share-based liabilities is reported within selling, general and administrative expense in the accompanying
consolidated statements of operations for the three and six month periods ended July 2, 2010. No awards were accounted for as share-based liabilities during the three or six month periods ended July 3, 2009. Approximately $0.4 million of
the compensation expense recognized during the three and six month periods ended July 2, 2010 relates to expense recognized upon the acceleration of vesting of all outstanding but unvested restricted stock awards that had previously been
granted to the Companys former Chief Executive Officer as of the effective date of termination on May 25, 2010.

No
issuances were made under the 2006 Equity Incentive Plan during the six months ended July 2, 2010. Stock compensation expense is primarily included in selling, general, and administrative expenses, and as an increase to additional paid-in
capital on the Companys consolidated balance sheets. As the restricted stock is issuable to the holder, subject to vesting provisions, with no consideration payable by the holder, the grant date fair value per share is based on the quoted
stock price on the date of the grant.

It is the Companys policy to issue new shares for equity awards pursuant to the
2006 Equity Incentive Plan. For awards that vest based solely on service conditions, the Company recognizes compensation expense on a straight-line basis over the requisite service period, which is generally from the grant of the awards through the
end of the vesting period. For awards with vesting that is contingent upon the achievement of performance conditions, the Company recognizes compensation expense on a straight-line basis over the requisite service period, which is generally from the
grant of the awards through the end of the vesting period, for each separately vesting tranche of the award. Restricted stock awards have generally been issued with a three-year vesting period. The Company reduces the compensation expense by an
estimated forfeiture rate which is based on actual experience. The Company assesses the likelihood that performance-based shares will be earned based on the probability of meeting the performance criteria. For those performance-based awards that are
deemed probable of achievement, expense is recorded, and for those awards that are deemed not probable of achievement, no expense is recorded. The Company assesses the probability of achievement each quarter.

The Companys restricted stock awards consist of both time-based and performance-based awards. Based on
the Companys estimates of forfeitures of time-based awards, and estimates relative to performance-based awards vesting and forfeitures, the Company would record aggregate compensation expense of $0.3 million subsequent to July 2,
2010, over a weighted average life of 1.0 years.

Other Incentive Compensation Plans

The Company has several stock option plans with outstanding grants that pre-date the 2006 Equity Incentive Plan. In 2005, the unvested
options were accelerated. No new options will be granted under pre-2006 equity plans. All unexercised options to purchase shares of common stock related to the Companys pre-2006 equity plans that were outstanding on the date of the
Companys emergence from bankruptcy were assumed by the reorganized Company upon emergence, other than those held by the Companys directors who did not continue as members of the reorganized Companys Board of Directors following
emergence. Such assumed options will be honored by the Company as if they had originally been granted for the issuance of the Companys post-emergence common shares. All of the Companys pre-2006 equity plans were cancelled upon the
Companys emergence from bankruptcy. Accordingly, no shares remain available for future issuance under these plans as of July 23, 2010. See Note 15 to Consolidated Financial Statements.

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying
options and the quoted price of common shares for the options that were in the money at July 2, 2010. There were no in-the-money shares at July 2, 2010.

9. Employee Benefit Plans

U.K. Defined Benefit Pension Plan

The Company maintains a pension plan in the United Kingdom that consists of two components: the Final Salary Plan (the
U.K. Plan), which is a defined benefit plan, and the Retirement Savings Plan, which is a defined contribution plan. In 1997, membership to the U.K. Plan was closed and in 2003 the Company was allowed to stop accruing additional benefits
to the participants. Benefits under the U.K. Plan were based on the employees years of service and compensation. Most of the beneficiaries of this plan are no longer employed by the Company. The Company follows a pension funding policy based
on widely used actuarial methods as permitted by regulatory authorities. The funded amounts reflect actuarial assumptions regarding compensation, interest and other projections. The assets of the U.K. Plan consist primarily of equity, real estate
and fixed income securities of U.K. and foreign issuers.

Japan Defined Benefit Pension Plan

The Company maintains a tax qualified pension plan in Japan that covers substantially all Japanese employees. The Company deposits funds
in various fiduciary-type arrangements and/or purchases annuities. Benefits are based on years of service and the employees compensation at retirement. Employees with less than twenty years of service to the Company receive a lump sum benefit
payout. Employees with twenty or more years of service to the Company, receive a benefit that is guaranteed for a certain number of years. Participants may under certain circumstances, receive a benefit upon termination of employment.

The assumptions that are used to value the costs and obligations of the plan reflect the Japanese economic environment. The Company
continues to fund the plan sufficient to meet current benefits as well as fund a portion of future benefits as permitted by regulatory authorities.

Pension and other benefit costs reflected in the accompanying consolidated statements of operations are based on a projected benefit method of valuation. Within the accompanying consolidated balance
sheets, pension plan benefit liabilities are included in accrued pension liability.

The table below sets forth the estimated
net periodic pension cost for the Japan defined benefit pension plan (in thousands):

10. Income Taxes

At the end of each interim reporting period, the Company determines its estimated annual effective tax rate, which is revised, as required, at the end of each successive interim period based on facts
known at that time. The estimated annual effective tax rate is applied to the year-to-date pre-tax income at the end of each interim period. The tax effect of significant unusual items is reflected in the period in which they occur. For purposes of
calculating the Companys annual effective tax rate, the Company has treated its bankruptcy-related costs as discrete items given the unusual nature of such costs. Since the Company is incorporated in Canada, it is required to use Canadas
statutory tax rate of 29.5% in the determination of the estimated annual effective tax rate. The Companys reported effective tax rate for continuing operations of 71.4% for the six months ended July 2, 2010 differed from the expected Canadian
federal statutory rate of 29.5%, primarily due to the tax treatment of bankruptcy-related costs, income earned in jurisdictions with varying tax rates, and the release of a portion of the Companys valuation allowance.

As part of the process of preparing the consolidated financial statements, the Company is required to estimate its income tax provision
(benefit) in each of the jurisdictions in which it operates. This process involves estimating the current income tax provision (benefit) together with assessing the future effects of temporary differences resulting from differing treatment of items
for tax and accounting purposes. The Company recognizes deferred tax assets and liabilities based on the differences between the financial statement carrying amount and the tax bases of assets and liabilities.

The Company records a valuation allowance if it is more likely than not that a portion of its deferred tax assets will not be realized.
The Company has considered historical losses, future taxable income, and expected reversals of existing temporary differences in assessing the need for a valuation allowance.

Except for the two dividend transactions discussed below, the Company has not provided any federal or state income taxes or foreign withholding taxes on the undistributed earnings of the Companys
foreign subsidiaries since such earnings have been indefinitely reinvested as defined in ASC 740, Income Taxes. The amount of the unrecognized deferred tax liability related to the undistributed earnings cannot be determined because of
the complexities associated with its hypothetical calculation. In the Companys 2009 financial statements, deferred tax was provided with respect to two dividends paid by the Companys two Japanese subsidiaries in
2010. Notwithstanding the 2010 dividends, the Company continues to assert that the remaining undistributed earnings are indefinitely reinvested.

As of July 2, 2010 and December 31, 2009, the Company had total unrecognized tax benefits of $5.1 million, all of which, if recognized would favorably affect its effective tax rate. The Company
expects that the changes in the unrecognized benefits within the next twelve months will not be material. Given the uncertainty regarding when the authorities will complete their examinations and the possible outcomes of their examinations, a
current estimate of the range of reasonably possible significant increases or decreases in income tax that may occur within the next twelve months cannot be made.

The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense. As of July 2, 2010 and December 31, 2009, the Company had approximately $1.1 million and
$1.0 million, respectively, of accrued interest and penalties related to uncertain tax positions. During the six months ended July 2, 2010, the Company recognized approximately $0.1 million in interest and penalties.

The Company files state and federal income tax returns in the United States and in foreign jurisdictions. Generally, the Company is no
longer subject to United States federal, state or local, or foreign income tax examinations by tax authorities for the years before 2000 as these years have been effectively settled. Currently, the Company is under examination in the United States
for tax years 2000 through 2005. The Companys income tax returns may be reviewed in the following countries and for the following periods under the appropriate statute of limitations: United States (2000-present), Canada (2003-present), United
Kingdom (2006-present), and Germany (2007-present).

Restructuring Charges

The Companys initial estimate for its liability for ongoing costs associated with workforce reductions and abandoned lease facilities are recorded at fair value. Generally, the expense and liability
recorded is calculated using discounted cash flows of the Companys estimated ongoing severance obligations and lease obligations, including contractual rental and build-out commitments, net of estimated sublease rentals, offset by related
sublease costs. In estimating the expense and liability for its lease obligations, the Company estimated: (i) The costs to be incurred to satisfy rental and build-out commitments under the lease, (ii) The lead time necessary to sublease
the space, (iii) The projected sublease rental rates, and (iv) The anticipated duration of subleases. The Company used a credit adjusted risk free rate of approximately 5% to discount the estimated cash flows for obligations with payments
due in excess of one year.

The Company reviews its assumptions and estimates quarterly and updates its estimates of the
liability as changes in circumstances require. The Companys estimates have changed in the past, and may change in the future, resulting in additional adjustments to the estimate of the liability, and the effect of any such adjustments could be
material. Changes to the Companys estimate of the liability are recorded as additional restructuring expense (benefit). In addition, because the Companys estimate of the liability includes the application of a discount rate to reflect
the time-value of money, the Company records imputed interest costs related to the liability each period. These costs are reflected in restructuring expense (benefit) on the accompanying consolidated statements of operations.

United Kingdom Restructuring

On February 29, 2008 and June 27, 2008, the Company executed agreements to sell assets related to its otherwise discontinued Impact product line, and certain assets related to its Laser Mark and
Excimer Laser product lines within the Precision Technology segment. The majority of the assets sold in the transaction represent inventory that had already been written off and were included as part of restructuring charges recorded in previous
periods. Payments received on asset sales that are due beyond one year are recorded as restructuring benefits when they are received. Accordingly, the sales resulted in a restructuring benefit of $0.1 million for the six months ended July 2,
2010. No amounts remain to be collected with respect to payments on these asset sales as of July 2, 2010. No amounts were received during either the three months ended July 2, 2010 or the three or six months ended July 3, 2009.

In December 2008, the Company announced the transfer of all volume related manufacturing from its Rugby, U.K. facility within
the Precision Technology segment, to the Companys facilities in China and the then-newly acquired Excel manufacturing sites. These activities were completed in 2009, at a total cost of $4.7 million, which is comprised of non-cash land and
building impairment charges of $3.6 million, employee severance costs of $1.0 million and facility related charges of $0.1 million. In December 2008, the Company recorded $3.9 million of this amount to restructuring expense. It was comprised of $3.6
million of non-cash land and building impairment charges and $0.3 million of employee severance costs. In addition to the amount recorded to restructuring, restatement related costs and other expense, the Company recorded a charge of $0.6 million
for inventory write-offs against cost of goods sold in 2008. No restructuring costs were recorded during the three or six months ended July 2, 2010. During the three and six months ended July 3, 2009, the Company recorded $0.2 million and
$0.7 million, respectively, in restructuring costs related to this restructuring plan. The amounts were comprised entirely of employee severance costs.

Germany Restructuring

As a result of restructuring programs undertaken in 2000 through 2004, and the subsequent sublease of the Companys Munich, Germany
facility within the Precision Technology segment in May 2007 through the end of its lease term, the Company carried a $2.1 million accrual for the cost of this lease as of December 31, 2009. As noted above, the Company regularly reviews its
assumptions with respect to excess space, including contractual lease payments and expected proceeds from the sublessor. During the year-ended December 31, 2009, the Company determined that it would no longer recover sublease payments from the
subtenant. Accordingly, the previous estimate of future sublease payments was revised. As a result, the Company recorded an additional restructuring charge of $1.3 million during the year-ended December 31, 2009 related to revised sublease
assumptions. The $0.1 million of expense recognized during the six months ended July 2, 2010 relates primarily to accretion charges recorded during the period. No significant adjustments were recorded either during the three months ended
July 2, 2010 or the three or six months ended July 3, 2009. As of July 2, 2010, cumulative expense related to this restructuring plan is $4.2 million. The remaining accrual of $1.5 million will be paid ratably over the remaining term
of the lease, which expires in January 2013.

On July 23, 2009, the Company initiated certain restructuring activities to
consolidate its German sales and distribution operations for the Precision Technology segment located in Munich, Germany with those of Excel Technology Europe, located in Darmstadt, Germany. The Companys lease obligations related to the
facility in Darmstadt, Germany were acquired in connection with the Companys acquisition of Excel in August 2008. These consolidation activities were completed in 2009, at a total cost of $0.2 million, which is comprised entirely of facility
related charges including a lease termination fee, required remaining lease payments and move related costs. Of the total restructuring charge of $0.2 million incurred during the year-ended December 31, 2009, $0.1 million was paid prior to
December 31, 2009. The remaining $0.1 million was paid during the six months ended July 2, 2010.

Novi
Restructuring

In the second quarter of 2008, the Company implemented a plan to close its Novi, Michigan facility, which
provided U.S. sales, applications and service support to a product line included in the Companys Precision Technology segment. The Novi facility was consolidated within the Companys Bedford, Massachusetts facility. In connection with
this action, the Company recorded a restructuring charge of $1.4 million during the year-ended December 31, 2008, consisting of $0.7 million for employee severance costs and $0.7 million in lease abandonment and related costs. The majority of the
employee severance payments were made in 2008, and the remaining amounts were paid in 2009. The lease costs are being paid ratably over the duration of the lease, which ends in 2012.

Bedford Restructuring

In September 2008, the Company consolidated its operations and facilities in Massachusetts to a new facility in Bedford, Massachusetts. At that time, the Company implemented a plan to reduce its United
States workforce by approximately 50 people and recorded a restructuring charge in the third quarter of 2008 of $3.0 million for severance costs. The Company charged $1.2 million of this amount to the Semiconductor Systems segment; $0.7 million to
the Precision Technology segment; and $1.1 million against corporate operations. The workforce reduction is expected to save the Company $6.8 million in annual salary and related costs. In December 2008, in connection with its consolidation of the
historic Scanner business with the then-newly acquired Scanner business of Excel, Cambridge Technology, Inc., the Company recorded a restructuring charge of $0.3 million relating to employee severance costs. The $0.3 million restructuring charge was
charged to the Precision Technology segment. The majority of these employee severance payments were made in 2008, and the remaining amounts were paid in 2009.

Restatement Related Costs and Other Charges

During the three and
six months ended July 2, 2010 and July 3, 2009, the Company incurred costs related to third parties, including auditors, attorneys, forensic accountants, and other advisors, for services performed in connection with the restatement of the
Companys previously issued financial statements as reported in its Annual Report on Form 10-K for the year-ended December 31, 2008 and its Quarterly Report on Form 10-Q for the quarter ended September 26, 2008, including, the SEC

restructuring charges were included in long-term liabilities classified as accrued restructuring, net of current portion in the accompanying consolidated balance sheets. The current portion of accrued restructuring charges is included in other
accrued expenses. See Note 5 to Consolidated Financial Statements.

12. Commitments and Contingencies

Operating leases

The Company leases certain equipment and facilities under operating lease agreements. Most of these lease agreements expire between 2010 and 2019. In the United Kingdom, where longer lease terms are more
common, the Company has land leases that extend through 2078. Under the terms of the facility leases, the Company is responsible to pay real estate taxes and other operating costs. In connection with its acquisition of Excel in 2008, the Company
assumed fourteen new facility leases used in manufacturing, research and development, sales and administration. The rent on certain leases is subject to escalation clauses in future years.

In 2007, the Company signed a 12-year lease for a 147,000 square foot facility in Bedford, Massachusetts. The terms of the lease provide
the Company with two renewal options for periods of five years each. The Company consolidated its Natick, Massachusetts; Billerica, Massachusetts and Wilmington, Massachusetts operations into this facility. The consolidation was completed in the
second quarter of 2008. Under the terms of the lease agreement, the landlord waived the first 5.5 months rent (representing a savings of $0.7 million). This savings is being amortized as a reduction to rent expense over the life of the amended
lease, and is included within deferred rent classified as other accrued expenses or other liabilities in the accompanying consolidated balance sheets based on the associated amortization period. The Company incurred $14.3 million in expenditures
through December 31, 2008 to fit-up and occupy the Bedford facility, of which the landlord provided $4.0 million in allowances. These expenditures were completed as of December 31, 2008. The landlord allowance has been included in the
Companys accompanying consolidated balance sheets in property, plant and equipment, and within deferred rent classified as other accrued expenses or other liabilities based on the associated amortization period. The property, plant and
equipment balance is being amortized to depreciation expense ratably over the life of the amended lease, and the landlord allowance is being offset as a reduction to rent expense, ratably over the life of the amended lease.

In February 2010, the Company entered into an Amended Lease Agreement with 125 Middlesex Turnpike, LLC to reduce the remaining term of
its current lease at 125 Middlesex Turnpike, Bedford, Massachusetts from approximately 10 years to 3 years from the new effective date of May 27, 2010. The rental payment will continue at $0.1 million per month. In the aggregate, the
modification reduces the Companys obligations under the current lease by approximately $10.8 million, of which $0.9 million relates to 2013, $1.6 million relates to 2014 and $8.3 million relates to periods thereafter. Accordingly, the
Companys remaining associated deferred rent and property, plant and equipment balances are being amortized over the adjusted lease term beginning on the effective date of the modification.

Line of Credit

As of July 2, 2010 and December 31, 2009, the Company had an outstanding line of credit to secure standby letters of credit that
were issued for certain facility operating leases, customer prepayments, warranty obligations, customs duties and bid bonds. The total amount available under the line of credit is approximately 500,000, of which 150,791 and 225,590
was available at July 2, 2010 and December 31, 2009, respectively.

Legal Proceedings

The Companys French subsidiary, GSI Lumonics SARL (Lumonics), is subject to a claim by a customer, SCGI, that a
Laserdyne 890 system delivered in 1999 had unresolved technical problems. During the third quarter of 2005, GSI France, parent of Lumonics, filed for bankruptcy protection, which was granted by the French court on July 7, 2005. On
April 18, 2006, the court fixed SCGIs claim against Lumonics at 598,079, plus court costs and expert fees of 85,945. SCGI accepted the courts determination and demanded that the Liquidator bring an action in the United
Kingdom against GSI Group Ltd., the parent corporation of GSI France. The Company does not believe it will be required to make any payments regarding this action. Accordingly, nothing has been accrued in the Companys accompanying consolidated
financial statements with respect to this claim.

On December 12, 2008, in connection with the delayed filing of its
results for the quarter ended September 26, 2008, and the announcement of a review of revenue transactions, a putative shareholder class action alleging federal securities violations was filed in the United States District Court for the
District of Massachusetts against the Company, a former officer and a then current officer and director. Specifically, the complaint alleges that the Company and the individual defendants violated Sections 10(b) and 20(a) of the Securities Exchange
Act of 1934 and Rule 10b-5 promulgated thereunder, and seeks recovery of damages in an unspecified amount. A lead plaintiff, Mason Tenders District Council Trust Funds, was appointed on May 8, 2009. In May 2010, the parties reached an agreement
in principle to settle the litigation. The settlement covers purchasers of the common stock of the Company between February 27, 2007 and June 30, 2009. On October 12, 2010, the United States District Court approved an order granting
the parties Motion for Certification of a Settlement Class and for Preliminary Approval of Class Action Settlement. The United States District Court has set February 16, 2011 as the date for the final Settlement Fairness Hearing. Although
the settlement agreement has not yet been approved by the United States District Court, the total settlement amount has been deposited into an escrow account. If the settlement is approved by the United States District Court, the Companys
contribution to the settlement amount will be limited to the balance of the Companys self-insured retention.

The
Company is also subject to various legal proceedings and claims that arise in the ordinary course of business. The Company does not believe that the outcome of these claims will have a material adverse effect upon its financial condition or results
of operations but there can be no assurance that any such claims, or any similar claims, would not have a material adverse effect upon its financial condition or results of operations.

Chapter 11 Cases

Certain creditor claims filed in connection with the Companys Final Chapter 11 Plan remain subject to final resolution.

On April 8, 2010, the Internal Revenue Service (IRS) filed amended proofs of claim aggregating approximately $7.7 million. On July 13, 2010, the Company filed a complaint, GSI
Group Corporation v. United States of America, in Bankruptcy Court to recover refunds totaling approximately $18.8 million in federal income taxes the Company overpaid to the IRS relating to tax years 2000 through 2008, together with
applicable interest. The complaint includes an objection to the IRS proofs of claim which the Company believes are not allowable claims and should be expunged in their entirety.

On May 13, 2010, the SEC filed a proof of claim in an indeterminate amount for penalties, disgorgement, and prejudgment interest
arising from possible violations of the federal securities laws. As noted below, the SEC has been conducting a formal investigation into certain pre-bankruptcy transactions and practices involving the Company and sent a Wells Notice to
the Company on September 16, 2010. Based on their investigation, the SEC indicated in their proof of claim that they may file a civil action against the Company in an appropriate forum. The Company is unable to predict the outcome of this
matter but, as noted below, the Company is cooperating fully with the SECs investigation.

In addition, under the terms
of the Final Chapter 11 Plan, the Company is obligated to make additional payments to the holders of 2008 Senior Notes claims in its Chapter 11 Cases if the amount of certain claims under the Final Chapter 11 Plan exceeds $22.5 million. The
additional payment, if any, would equal approximately $1.00 for each dollar by which the $22.5 million cap amount is exceeded. The Company cannot make a final determination of the amount, if any, the Company

may owe as a result of this provision until certain claims filed in connection with its Chapter 11 Cases, including the IRS and SEC claims described above, are finally resolved. The amount of
such claims, based on the known and estimated amount of such claims, is currently well below the $22.5 million cap amount. As the Company does not believe it is probable that its losses under these claims will exceed $22.5 million, nothing has been
accrued in the Companys accompanying consolidated financial statements with respect to this potential obligation.

SEC Investigation

On May 14, 2009, the Company received a notice from the SEC indicating that the SEC is conducting a formal investigation relating to its historical accounting practices and the restatement of its
historical consolidated financial statements. On September 16, 2010, the Company received a Wells Notice from the SEC, stating that the Staff is considering recommending that the Commission institute a civil injunctive action or
administrative proceeding against the Company, alleging that the Company violated various provisions of the Securities Act and the Securities Exchange Act, and providing the Company with the opportunity to make a submission to the Staff in
connection therewith. In connection with the contemplated action, the SEC may seek a permanent injunction or cease-and-desist order, disgorgement, prejudgment interest and the imposition of a civil penalty. The Company is cooperating fully with the
SECs investigation.

Issuance of Unregistered Securities

The Company inadvertently issued unregistered shares of common stock under its 2006 Equity Incentive Plan as a result of its failure to
file with the SEC a registration statement on Form S-8. The 2006 Equity Incentive Plan was approved by the Companys shareholders in May 2006. From March 2007 through March 2010, the Company issued approximately 773,037 duly authorized common
shares with a total fair market value at the date of issuance of approximately $3,889,796 to fifty-two employees and directors under its 2006 Equity Incentive Plan. As a result, the Company may be subject to civil litigation, enforcement
proceedings, fines, sanctions and/or penalties. The Companys common shares, including those issued under the 2006 Equity Incentive Plan, were exchanged for new common shares in connection with the Companys emergence from bankruptcy
pursuant to the exemption from registration under §1145 of the Bankruptcy Code and are now freely tradable by holders who are not deemed to be underwriters.

Guarantees and Indemnifications

In the normal course of its
operations, the Company executes agreements that provide for indemnification and guarantees to counterparties in transactions such as business dispositions, the sale of assets, sale of products and operating leases. Additionally, the by-laws of the
Company require it to indemnify certain current or former directors, officers, and employees of the Company against expenses incurred by them in connection with each proceeding in which he or she is involved as a result of serving or having served
in certain capacities. Indemnification is not available with respect to a proceeding as to which it has been adjudicated that the person did not act in good faith in the reasonable belief that the action was in the best interests of the Company. On
June 5, 2009, the Board of Directors of the Company approved a form of indemnification agreement to be implemented by the Company with respect to its directors and officers. The form of indemnification agreement provides, among other things,
that each director and officer of the Company who signs the indemnification agreement shall be indemnified to the fullest extent permitted by applicable law against all expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by such officer or director in connection with any proceeding by reason of his or her relationship with the Company. In addition, the form of indemnification agreement provides for the advancement of expenses incurred by such
director or officer in connection with any proceeding covered by the indemnification agreement, subject to the conditions set forth therein and to the extent such advancement is not prohibited by law. The indemnification agreement also sets out the
procedures for determining entitlement to indemnification, the requirements relating to notice and defense of claims for which indemnification is sought, the procedures for enforcement of indemnification rights, the limitations on and exclusions
from indemnification, and the minimum levels of directors and officers liability insurance to be maintained by the Company.

Credit Risks and Other Uncertainties

The Company maintains
financial instruments such as cash and cash equivalents and trade receivables. From time to time, certain of these instruments may subject the Company to concentrations of credit risk whereby one institution may hold a significant portion of the
cash and cash equivalents, or one customer may compose a large portion of the accounts receivable balances.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)



There was no concentration of credit risk related to the Companys position in
trade accounts receivable as of either July 2, 2010 or December 31, 2009. No individual customer represented 10% or more of the Companys outstanding accounts receivable at July 2, 2010 or December 31, 2009. Credit risk with
respect to trade accounts receivable is generally minimized because of the diversification of the Companys operations, as well as its large customer base and its geographical dispersion.

The Company acquired certain auction rate securities in connection with its purchase of Excel. In current markets, the fair value of
these auction rate securities is not able to be ascertained by observable inputs. See Note 3 to Consolidated Financial Statements for further discussion. As of July 2, 2010, the Company had liquidated all of its previously held auction rate
securities.

Certain of the components and materials included in the Companys laser systems and optical products are
currently obtained from single source suppliers. There can be no assurance that a disruption of this outside supply would not create substantial manufacturing delays and additional cost to the Company.

The Companys operations involve a number of other risks and uncertainties including, but not limited to, the cyclicality of the
semiconductor and electronics markets, the effects of general economic conditions, rapidly changing technology, and international operations.

13. Segment Information

The Company identifies its reportable segments based on its operating and reporting structure. As a result of the Companys
acquisition of Excel in 2008, it reassessed its segment reporting based on the operating and reporting structure of the combined company. In 2008, the Company concluded that the acquisition of Excel resulted in the establishment of a third segment
which was comprised solely of the operations of the then-newly acquired entity. In 2009, the Company changed the structure of its internal organization in a manner that caused the composition of its reportable segments to change. More specifically,
certain portions of a specific product line within the Precision Technology segment were transferred to the Excel segment. The Companys reportable segment financial information has been restated to reflect the updated reportable segment
structure for all periods presented. The Companys reportable segments and their principal activities consist of the following:

Precision Technology

This segments products include
technologies for precision motion, linear and rotary motion control, medical printers, lasers, electro-optical components and precision optics used in a broad range of commercial and semiconductor applications. These products are used in the
electronics, aerospace, materials processing, data storage, imaging and other light industrial markets. The products are designed and manufactured at the Companys facilities in the United States, Europe and Asia.

Semiconductor Systems

The Companys Semiconductor Systems segments products are designed and manufactured at its facility in the United States. Specific applications include laser repair to improve yields in the
production of memory chips; laser marking systems for work-in-process management and traceability of silicon wafers; laser trimming of linear and mixed signal integrated circuits and chip resistors; and inspection of solder paste and component
placement on printed circuit boards. The Semiconductor Systems segment also derives significant revenues from parts and service to its installed base.

Excel

This segments products include lasers, electro-optical
components, precision optics and photonics-based solutions primarily consisting of laser systems used in a broad range of commercial and scientific research applications. These products are used in the electronics, aerospace, materials processing,
data storage, imaging and other light industrial markets. The products are designed and manufactured at the Companys facilities in the United States and Europe.

14. Related Party Transactions

Richard B. Black, the Chairman of the Company prior to the Companys emergence from Chapter 11 bankruptcy protection, is also the President and Chief Executive Officer of ECRM, Inc., a company which
manufactures laser systems equipment for the printing and publishing industry and which is a customer of the Company. Following the Companys emergence from bankruptcy on July 23, 2010, ECRM, Inc. is no longer considered a related
party. All sales to ECRM, Inc. were made pursuant to the Companys standard contract terms and conditions. The transactions with ECRM, Inc. during the six months ended July 2, 2010 were on the same terms and conditions as similar
transactions consummated in previous periods which had been reviewed by the Nominating and Governance Committee whereby ECRM, Inc. was deemed to have received no favored commercial treatment.

Michael Katzenstein, Chief Restructuring Officer of the Company since May 14, 2010, is employed by FTI Consulting, Inc.
(FTI). The Company engaged FTI in May 2010 to provide for the services of Mr. Katzenstein and certain other temporary employees and management services to support Mr. Katzenstein in his role. Mr. Katzenstein reports
directly to the Board of Directors. The Company has a separate arrangement with another segment of FTI, which commenced in November 2009, to provide certain accounting and financial reporting services. This segment of FTI reports directly to the
Board of Directors. As a result of these arrangements, the Company incurred fees owed to FTI for services rendered during the three and six months ended July 2, 2010.

The Company recorded sales to and raw material purchases from Sumitomo Heavy Industries Ltd., a significant shareholder, and recorded raw material purchases from Integrated Dynamics Engineering Gmbh, a
related party to JEC II Associates, LLC, a significant shareholder. Following the Companys emergence from bankruptcy on July 23, 2010, Sumitomo Heavy Industries Ltd. is no longer considered a related party. The amounts and terms of these
transactions were equivalent to similar third-party transactions.

15. Subsequent Events

U.K. Defined Benefit Pension Plan

Based on the results of a new
funding valuation completed in 2010, the Company increased its annual contributions to the U.K. Plan from approximately $0.6 million to $0.8 million for a period of 10 years and 5 months beginning September 2010, including an additional one-time
lump-sum payment of approximately $1.6 million, of which $0.8 million was paid in September 2010 and $0.8 million was paid in December 2010.

Chapter 11 Bankruptcy Cases

On July 23, 2010, the Company
successfully emerged from bankruptcy as a reorganized company pursuant to the Final Chapter 11 Plan after voluntarily filing for bankruptcy on November 20, 2009. The Final Chapter 11 Plan deleveraged the Companys balance sheet by reducing
debt and increasing stockholders equity. The financial restructuring was accomplished through a debt-for-equity exchange and by using the proceeds from a shareholder rights offering and cash on hand to reduce outstanding indebtedness.

Upon the Companys emergence from Chapter 11 bankruptcy proceedings on July 23, 2010, the Company was not required
to apply fresh-start accounting based on the provisions of ASC 852 due to the fact that the pre-petition holders of the Companys outstanding common shares immediately before confirmation of the Final Chapter 11 Plan received more than 50% of
the Companys outstanding common shares upon emergence. Accordingly, a new reporting entity was not created for accounting purposes.

Below is a summary of the significant events affecting the Companys capital structure as a result of the effectiveness of the Final Chapter 11 Plan.

Equity Transactions

On the Effective Date, the Company issued an aggregate of 100,002,179 post-emergence new common shares (New Common Shares)
pursuant to the Final Chapter 11 Plan. Consistent with the Confirmation Order and applicable law, the Company relied on Section 1145(a)(1) of the Bankruptcy Code to exempt from the registration requirements of the Securities Act of 1933, as
amended (the Securities Act), the issuance of such New Common Shares. The New Common Shares were issued as a result of the following transactions:



| |  |  | Rights offering: The Company conducted a rights offering in which the Company offered for sale to existing shareholders up to a maximum of $85
million of its common shares to be issued upon emergence from bankruptcy at a purchase price per share of $1.80 (the Price Per Share). As provided in the Final Chapter 11 Plan, the cash proceeds from the rights offering were used to pay
down the Companys $210.0 million of 11% unsecured senior notes due 2013 (the 2008 Senior Notes). As such, 37,756,069 of the Companys common shares were subscribed for a total subscription price of $67,960,924. Of the total
common shares subscribed for in the rights offering, $64,889,486 were subscribed for by payment in cash and $3,071,438 were subscribed for by exchange of the 2008 Senior Notes. As a result of the rights offering and the shares issued pursuant to the
backstop commitment described below, the Companys shareholders prior to the emergence from bankruptcy retained approximately 86.1% of the Companys capital stock following emergence (subject to the distribution of shares placed in reserve
pending resolution of certain litigation matters unrelated to the Chapter 11 Cases). The remaining 13.9% of the Companys capital stock was issued to the holders of the 2008 Senior Notes in partial exchange of such notes and pursuant to the
commitment of certain holders to backstop the Rights Offering.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Backstop commitment: Pursuant to the Final Chapter 11 Plan, and subject to the terms and conditions of a Backstop Commitment Agreement, certain
note holders agreed to backstop the entire rights offering. Regardless of the number of shares purchased in the rights offering, the backstop investors agreed to purchase a minimum of $20 million of common shares by exchanging the principal amount
of their 2008 Senior Notes for common shares at the Price Per Share. Because the difference between the total amount of the shares offered and the shares subscribed for in the rights offering was less than $20 million, 11,111,111 common shares for a
total of the backstop commitment amount of $20 million were issued pursuant to the backstop commitment. In addition, the backstop investors who agreed to backstop the rights offering received a cash backstop fee of $4.2 million, which represented 5%
of the $85 million maximum proceeds from the offering. The backstop fee is reflected in reorganization items in the consolidated statements of operations for the three and nine months ended October 1, 2010.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Supplemental equity exchange: Pursuant to and in accordance with the Final Chapter 11 Plan, the holders of the 2008 Senior Notes exchanged an
aggregate principal amount of $5.0 million of 2008 Senior Notes for post-emergence new common shares at the Price Per Share (the Supplemental Equity Exchange). In connection with the Supplemental Equity Exchange, the Company issued
2,777,778 new common shares on the Effective Date on a pro rata basis to the holders of the 2008 Senior Notes.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Existing equity holders: The Company issued 45,375,994 New Common Shares on the Effective Date to holders of the common shares issued and
outstanding immediately prior to the Effective Date and to holders of vested share rights.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, on
the Effective Date and pursuant to the terms of the Final Chapter 11 Plan, the Company placed 2,981,227 New Common Shares in a reserve (the Reserve Shares) to be held in escrow for the benefit of the holders of Section 510(b) Claims
(as defined in the Final Chapter 11 Plan) pending the final disposition of that certain putative shareholder class action entitled Wiltold Trzeciakowski, Individually and on behalf of all others similarly situated v. GSI Group Inc., Sergio
Edelstein, and Robert Bowen, Case No. 08-cv-12065 (GAO), filed on December 12, 2008, in the United States District Court (see Note 12 to Consolidated Financial Statements for additional information). Following final disposition of the
class action, the Reserve Shares will be released to the holders of the Section 510(b) Claims or to the holders of the Companys common shares and holders of common shares that had vested on the Effective Date but had not been issued
immediately prior to the Effective Date.

Furthermore, on and as of the Effective Date, pursuant to the Final Chapter 11 Plan
and the Confirmation Order, all of the issued and outstanding shares of capital stock of the Company, including all options, calls, rights, participation rights, puts, awards, commitments or any other agreement to acquire shares of capital stock of
the Company that existed prior to the Effective Date, were cancelled and in exchange therefore, holders of such interests received distributions pursuant to the terms of the Final Chapter 11 Plan as summarized above.

Additionally, all unvested restricted stock awards and unexercised options to purchase shares of common
stock related to the Companys 2006 Equity Incentive Plan and pre-2006 equity plans that were outstanding on the date of the Companys emergence from bankruptcy were assumed by the reorganized Company upon emergence, other than those held
by the Companys directors who did not continue as members of the reorganized Companys Board of Directors following emergence. Such assumed restricted stock awards and options will be honored by the Company as if they had originally been
granted for the issuance of the Companys post-emergence common shares. The Companys 2006 Equity Incentive Plan and pre-2006 equity plans were cancelled upon the Companys emergence from bankruptcy.

Lastly, on and as of the Effective Date, the Companys stock repurchase plan and
shareholder rights plan were also cancelled upon the Companys emergence from bankruptcy.

Debt Transactions

Upon the Companys emergence from bankruptcy, the Company consummated a series of transactions that reduced its
outstanding debt from $210.0 million under the 2008 Senior Notes to $107.0 million. The Company reduced its debt by making cash payments of $74.9 million and exchanging debt for common shares totaling $28.1 million. The remaining $107.0 million of
2008 Senior Notes were cancelled and replaced by the 12.25% Senior Secured PIK Election Notes due July 23, 2014 (the New Notes) issued under that certain indenture (the New Indenture), by and among GSI US, as issuer, the
Mellon Trust Company, N.A., as trustee (the Trustee).

A summary of the transactions affecting the Companys
debt balances is as follows:



|                                                                          |  |   |          |

|Repayment of debt with proceeds from Rights Offering                      |  |   | (64,889  | )
|Exchange of debt for common shares pursuant to Rights Offering            |  |   | (3,071   | )
|Exchange of debt for common shares under the Backstop Agreement           |  |   | (20,000  | )
|Exchange of debt for common shares under the Supplemental Equity Exchange |  |   | (5,000   | )
|Repayment in cash                                                         |  |   | (10,000  | )
|Exchange of 2008 Senior Notes for New Notes                               |  |   | (107,040 | )
|                                                                          |  |   |          |  
|Gain (loss) on extinguishment                                             |  | $ |         |  
|                                                                          |  |   |          |  

The Companys issuance of the New Notes in exchange for the 2008 Senior Notes is accounted for as an
extinguishment of debt as the terms of the New Notes were deemed to be substantially different. As a result, the New Notes were recorded at fair value and were compared to the carrying value of the 2008 Senior Notes as of July 23, 2010 to
determine the debt extinguishment gain or loss to be recognized. The Company determined that fair value of the New Notes equaled the carrying value of the 2008 Senior Notes and as a result, no gain or loss was recognized. In addition, the Company
capitalized approximately $1.6 million of legal and other third-party fees and will recognize these costs over the four year holding period of the New Notes.

Interest accrues on the New Notes at a rate of 12.25% per year and is payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, commencing on
August 15, 2010. GSI US may elect to pay the interest in cash, or, under certain conditions, by increasing the principal amount of the New Notes or issuing additional notes on the same terms and conditions as the existing New Notes
(PIK). Furthermore, until the Company becomes current in its reporting obligations under the Securities Exchange Act of 1934, as amended (the Exchange Act) and until the Companys common shares are listed on an Eligible
Market (as defined in the New Indenture), the rate of interest under the New Notes will be increased by an additional 2% per annum, payable by PIK beginning after August 15, 2010. The interest rate on the New Notes may be increased under
certain defaults, as defined in the New Indenture. Interest PIK notes issued and PIK payments in lieu of cash payments accrue at a rate of 13%.

The New Notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by the Guarantors. The obligations of GSI US under the New Indenture and the New Notes, and each of
the Guarantors obligations under the New Indenture, will be secured by a first priority perfected security interest on all of the U.S. property and assets of GSI US and of all Guarantors, including pledges of up to 662/3% of the stock of the foreign subsidiaries held by GSI US and the
respective Guarantors.

GSI US may, at any time, redeem up to 100% of the aggregate principal amount of the New
Notes (including any such notes issued after the Effective Date), in whole or in part, at a redemption price equal to 100% of the principal amount of the New Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to, but not
including, the date of redemption. To the extent the aggregate principal amount of outstanding indebtedness under a working capital facility which GSI US may enter into pursuant to the terms of the New Indenture exceeds $20 million or upon certain
asset sales, GSIG or GSI US will be required to offer to use such excess working capital proceeds or excess net proceeds, as applicable, to make an offer to purchase a portion of the New Notes at 100% of the principal amount thereof, plus accrued
and unpaid interest to the date of purchase.

The terms of the New Notes require GSI US, GSIG and certain of their subsidiaries to
comply with covenants that restrict some of their corporate activities, including the ability of GSI US, GSIG and such subsidiaries to incur additional debt, pay dividends, create liens, make investments, sell assets, repurchase equity or
subordinated debt, or engage in specified transactions with affiliates.

Noncompliance with any of the covenants without cure
or waiver would constitute an event of default under the New Notes. An event of default resulting from a breach of a covenant may result, at the option of the holders, in an acceleration of the principal and interest outstanding. At any time after
the occurrence and during the continuance of an event of default, the New Notes will bear interest at a rate per annum equal to the then applicable rate plus 2% per annum (the Default Rate). The New Notes also contain other
customary events of default (subject to specified grace periods), including defaults based on events of bankruptcy and insolvency, cessation of effectiveness of certain related security documents and nonpayment of principal, interest or fees when
due.

On the Effective Date and in connection with the New Notes, GSI US entered into a Security Agreement (the Security
Agreement) with the Guarantors and the Trustee, as collateral agent thereunder, pursuant to which GSI US and the Guarantors, as grantors under the Security Agreement, provided for the grant of a first priority perfected security interest in
all (except as otherwise provided therein) of the U.S. property and assets of GSI US and each Guarantor to secure GSI USs obligations under the New Indenture and the New Notes and each Guarantors obligations under the New Indenture.

Appointment of Chief Executive Officer

On November 16, 2010, the Company entered into an employment agreement with John Roush to serve as the Companys Chief Executive Officer beginning no later than February 1, 2011. Under the
terms of Mr. Roushs employment agreement, Mr. Roush will be paid an annual base salary of $500,000 and receive a sign-on bonus of up to $176,375. Mr. Roush will also receive a sign-on equity award of 1,000,000 restricted stock
units (the Sign-on RSUs) pursuant to the Companys 2010 Incentive Award Plan (the 2010 Incentive Plan). The Sign-on RSUs vest in substantially equal installments on each of the first three anniversaries of
Mr. Roushs employment date and become fully vested immediately prior to a Change in Control, as defined in Mr. Roushs employment agreement. During the period beginning on his initial date of employment and ending immediately
prior to the grant of the Sign-On RSUs, Mr. Roush may, under certain circumstances, be entitled to receive a one-time lump sum cash payment equal to the fair market value of 1,000,000 shares of the Companys common shares in lieu of the
Sign-On RSUs. In addition, Mr. Roush is eligible to receive an annual performance-based cash bonus equal to 85% of Mr. Roushs annual base salary. The annual bonus is payable based upon the attainment of individual and Company
performance goals established by the Board of Directors. If the Company and/or Mr. Roush does not attain performance target levels with respect to fiscal year 2011, the Company has agreed to pay Mr. Roush a minimum bonus in an amount equal
to 80% of his target bonus. Mr. Roush will also be granted an annual equity compensation award in March 2011 in the form of 400,000 restricted stock units (the 2011 RSUs) pursuant to the 2010 Incentive Award Plan. The 2011 RSUs vest
in substantially equal installments on each of the first three anniversaries of the date of grant and become fully vested immediately prior to a Change in Control. Commencing after fiscal 2011, during the term of his employment under his employment
agreement, Mr. Roush will be granted an annual equity compensation award with a value equal to 200% of his annual base salary. Mr. Roush is also entitled to certain payments and benefits upon termination by the Company without Cause, as
defined in Mr. Roushs employment agreement, by Mr. Roush for Good Reason, as defined in the Mr. Roushs employment agreement, or due to death or Disability, as defined in Mr. Roushs employment agreement.

Approval of Incentive Plan

On November 23, 2010, the Companys shareholders approved the Companys 2010 Incentive Plan. The 2010 Incentive Plan had previously been approved and adopted by the Companys Board of
Directors on October 13, 2010, subject to the approval of the Companys shareholders. Pursuant to the Final Chapter 11 Plan, the Companys previous equity incentive plans were cancelled upon the Companys emergence from
bankruptcy on July 23, 2010. The Final Chapter 11 Plan required the Company to establish and implement a new management incentive plan under which shares in an amount not to exceed 8% of the fully-diluted common stock will be reserved for
issuance thereunder. There are 8,695,841 shares available for future grants under the 2010 Incentive Plan, subject to adjustment as set forth in the 2010 Incentive Plan. The 2010 Incentive Plan provides for the grant of incentive stock options,
non-qualified stock options, restricted stock, restricted stock units, stock appreciation rights, deferred stock, deferred stock units, dividend equivalents, performance awards and stock payments (collectively referred to as Awards) to
employees, consultants and directors. The 2010 Incentive Plan provides for specific limits on the number of shares that may be subject to different types of Awards and the amount of cash that can be paid with respect to different types of Awards.
The 2010 Incentive Plan will expire and no further Awards may be granted after November 23, 2020, the tenth anniversary of its approval by shareholders.

Approval of Reverse Stock Split

On November 23, 2010, the Companys shareholders approved an amendment to its Articles to effect a reverse stock split of its
common shares by a ratio of 1-for-2, 1-for-3, 1-for-4 or 1-for-5, with the exact ratio to be determined by the Board of Directors in its discretion, and to authorize the Board of Directors to implement the reverse stock split at any time prior to
February 23, 2011. After the reverse stock split, the shareholders will not receive fractional post-reverse stock split shares in connection with the reverse stock split. Shareholders of record who otherwise would hold fractional shares will be
entitled to round up such fractional share to a full share. As soon as practicable after the completion of the reverse stock split, the Company intends to file an application to list its common shares on the NASDAQ Global Market. There can be no
assurance of when or if the Companys common shares will be listed on the NASDAQ Global Market or another stock exchange. On December 6, 2010, the Companys Board of Directors approved a 1-for-3 reverse stock split, which the
Company expects to become effective prior to the end of 2010.

Business Overview

GSI Group, Inc. (GSIG) and its subsidiaries (collectively referred to as the Company, we, us, our) design, develop, manufacture and sell
photonics-based solutions (consisting of lasers, laser systems and electro-optical components), precision motion devices, and associated precision motion control technology and systems. Our customers incorporate our technology into their products or
manufacturing processes, for a wide range of applications in the industrial, scientific, electronics, semiconductor, medical and aerospace markets. Our products enable customers to make advances in materials and processing technology and to meet
extremely precise manufacturing specifications, including device complexity and miniaturization.

The photonics and
electro-optical industry is subject to intense competition and rapid technological developments. Our strength and success is dependent upon developing and delivering successful, timely and cost effective solutions to our customers. For us to
maintain our performance, we believe we must continue to increase our operational efficiencies, improve and refine our existing products, expand our product offerings and develop new applications for our technology.

We strive to create shareholder value through:



| |  |  | Organic sales growth by delivering a consistent stream of successful new product launches,
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Generating high levels of cash flow from operations, and
| | - |  | --------------------------------------------------------



| |  |  | Acquiring and successfully integrating businesses that have complementary and established core competencies.
| | - |  | ------------------------------------------------------------------------------------------------------------

We group our business units, also known as product lines, into three segments: Precision Technology, Semiconductor Systems, and Excel.
Our Precision Technology segment primarily sells components to original equipment manufacturers (OEMs), who then integrate products of our Precision Technology segment into application specific products or systems. Our Precision Technology
segments OEM products include those based on its core competencies in laser, precision motion and motion control technology. Our Semiconductor Systems segment designs, develops and sells production systems that process semiconductor wafers
using laser beams and high precision motion technology. Our Semiconductor Systems segment sells manufacturing systems to integrated device manufacturers and wafer processors. Our Excel segment designs, manufactures and markets photonics-based
solutions consisting of lasers, laser-based systems, precision motion devices and electro-optical components, primarily for industrial and scientific applications. Our Excel segment primarily sells components to OEMs, who then integrate the Excel
segments products into application specific products or systems.

Strategy

We strive to expand our presence in the markets we serve both through organic growth and strategic acquisitions. This strategy led to our
acquisition of Excel Technology, Inc. (Excel) in the third quarter of 2008. The acquisition of Excel represented a major step in our effort to penetrate attractive markets that depend on photonics-based solutions. The acquisition also
allowed our Precision Technology segment to expand our presence in several markets that it serves. During 2008 and 2009, we undertook steps to integrate parts of Excels business with those of GSI. As a result of the bankruptcy filing by GSI
Group, Inc. and two of our wholly-owned U.S. subsidiaries in November 2009, further integration of the two businesses was delayed. We expect to have additional opportunities to integrate the two businesses in the future but our primary focus in the
near term will be on the continued development and introduction of new products, increasing our presence in markets we currently serve and identifying new market opportunities for new and existing products. In addition, we may explore potential
divestments of non-strategic businesses.

Pursuant to the terms of the fourth modified joint Chapter 11 plan of
reorganization, as supplemented, (the Final Chapter 11 Plan) it was agreed that our reorganized Board of Directors would be comprised of seven directors, to include two directors selected by the noteholders, two directors with industry
expertise selected by the Equity Committee (as defined in the Final Chapter 11 Plan), one director selected by mutual agreement between the noteholders and the Equity Committee, one director to be selected from our Board of Directors prior to
emergence, and the chief executive officer (CEO) of our reorganized Company. As of July 2, 2010, we did not have a permanent CEO or a permanent chief financial officer (CFO). On April 1, 2010, we appointed a
principal financial officer who has been serving and will continue to serve as our principal financial officer until such time that a permanent CFO is identified and hired. Our former chief restructuring officer has been serving and continues to
serve as our principal executive officer until such time that a permanent CEO is identified and hired. On November 16, 2010, we entered into an employment agreement with John Roush to serve as our CEO beginning no later than February 1,
2011.

Significant Events

The following significant transactions and events occurred in 2009 and 2010 through the filing of this Quarterly Report on Form 10-Q:



| | 1. | Chapter 11 BankruptcyOn November 20, 2009 (the Petition Date), GSI Group, Inc. and two of its wholly-owned subsidiaries, GSI Group Corporation
and MES International, Inc. (the Debtors), filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code (the Bankruptcy Code) (the Chapter 11 Cases). Following the Petition Date, the
Debtors continued to operate their businesses as debtors-in-possession. On May 27, 2010, the United States Bankruptcy Court entered an order confirming and approving the Final Chapter 11 Plan for the Debtors and on July 23, 2010, the
Debtors emerged from bankruptcy. Refer to Notes 1, 6, 12 and 15 to Consolidated Financial Statements of this Quarterly Report on Form 10-Q for additional information regarding the Chapter 11 Cases.

| | 2. | Rights OfferingOur $210.0 million of debt (the 2008 Senior Notes) was restructured in the Chapter 11 bankruptcy proceedings. On July 23,
2010, we emerged from bankruptcy and consummated the rights offering (the Rights Offering) contemplated under the Final Chapter 11 Plan. We raised approximately $64.9 million in cash proceeds in the Rights Offering which were used to pay
down a portion of the obligations due with respect to the 2008 Senior Notes. The remaining obligations due with respect to the 2008 Senior Notes for unpaid principal and accrued interest were satisfied through the issuance of new common shares,
cash payments and the issuance of $107.0 million new 12.25% Senior Secured PIK Election Notes (the New Notes) which mature in July 2014.

| | 3. | Reorganization ItemsReorganization items represent amounts that are recorded in our consolidated financial statements as a result of the bankruptcy
proceedings. During the three and six months ended July 2, 2010, we recorded charges of $10.6 million and $20.2 million, respectively, primarily for professional fees related to our reorganization.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4. | Restructuring, Restatement Related Costs and Other ChargesDuring the three months ended July 2, 2010 and July 3, 2009, we recorded restructuring,
restatement related costs and other charges of $1.0 million and $3.1 million, respectively. During the six months ended July 2, 2010 and July 3, 2009, we recorded restructuring, restatement related costs and other charges of $1.7 million

|(1) | Sales of the Precision Technology segments products to the Excel and Semiconductor Systems segments and sales of the Excel segments products to the
Precision Technology and Semiconductor Systems segments.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Sales of the various product lines that comprise our
Precision Technology segment increased by $14.7 million, or 85.8%, from $17.1 million during the three months ended July 3, 2009 to $31.8 million during the three months ended July 2, 2010. Sales increased across all product lines that
comprise the Precision Technology segment, except for our optics product line. Sales during the three months ended July 2, 2010 increased compared with the three months ended July 3, 2009, primarily due to higher demand from OEM and other
customers who in turn have experienced an increase in demand for their products due to an improving world economy. The second quarter of 2009 was a period of particularly weak demand for our products due to the tight credit conditions and low levels
of personal consumption and capital investment that existed at that time. Our product line that supplies drilling components to leading printed circuit board (PCB) drilling manufacturers, which serve a variety of consumer industries
including electronics and automobiles, accounted for approximately $7.3 million of the $14.7 million increase in sales for this segment.

Semiconductor Systems segment sales transactions are generally multiple element arrangements that are accounted for in accordance with the provisions of ASC 605-25, Multiple Element
Arrangements. Due to the multiple element nature of Semiconductor Systems segment sales transactions, sales in any given period may not correspond to shipments. Sales for 2010 and 2009 of our Semiconductor Systems segment include the
recognition of revenue that had been deferred from orders placed by customers prior to 2009, but had not been recognized in the period in which shipments occurred due to previously undelivered elements or unresolved commitments. The revenue related
to these orders is recognized once the final deliverables or commitments are resolved.

Semiconductor Systems segment sales
decreased by $6.5 million, or 36.3%, from $17.8 million during the three months ended July 3, 2009 to $11.3 million during the three months ended July 2, 2010. The decrease is primarily attributable to the recognition of revenue from
orders placed by customers prior to 2009, but that had not been recognized until the quarter ended July 3, 2009 when the deliverables or commitments were resolved. We recognized $15.1 million in sales during the three months ended July 3,
2009, as compared to $0.3 million for the three months ended July 2, 2010 related to these orders. Excluding the impact of this revenue recognized in the second quarter of 2009, the Semiconductor Systems segment experienced a rebound in sales
primarily due to higher sales of wafer marking equipment and equipment upgrades in 2010. The semiconductor industry is highly cyclical, causing a cyclical impact on our financial results. Our revenue is driven by the capital expenditure budgets and
spending patterns of our customers, who often delay or accelerate purchases in reaction to variations in their business. The level of capital expenditures by these customers depends on the current and anticipated market demand, which began
rebounding in 2010 from historically low levels in previous years.

The Excel segment was established following the
acquisition of Excel in August 2008. Originally, the Excel segment was comprised solely of the operations of the then-newly acquired entity. In 2009, we changed the structure of our internal organization in a manner that caused the composition of
our reportable segments to change. More specifically, certain portions of a specific product line within the Precision Technology segment were transferred to the Excel segment. Our reportable segment financial information has been restated to
reflect the updated reportable segment structure for all periods presented. Sales of the various product lines that comprise our Excel segment increased by $16.0 million, or 54.7%, from $29.1 million during the three months ended July 3, 2009
to $45.1 million for the three months ended July 2, 2010. The increase in sales was primarily attributable to a strong rebound in sales of lasers, scanners and optics during the three months ended July 2, 2010 as compared to the three
months ended July 3, 2009.

Gross profit as a percentage of sales can be influenced by a number of factors including product mix,
pricing, volume, costs for raw materials and outsourced manufacturing, warranty costs and charges related to excess and obsolete inventory, at any particular time.

Gross profit of the Precision Technology segment increased by $8.4 million, or 121.4%, from $6.9 million during the three months ended July 3, 2009 to $15.3 million during the three months ended
July 2, 2010, primarily due to the increase in sales. The Precision Technology segments gross profit margin was 48.1% during the three months ended July 2, 2010, compared with a gross profit margin of 40.3% during the three months
ended July 3, 2009. Our gross margin, in terms of dollars, improved due to the significant increased demand for our products. The improvement in gross profit margin of our Precision Technology segment was primarily attributable to higher
capacity utilization resulting from the increase in demand for our products, partially offset by increases in excess and obsolete inventory provisions.

During the three months ended July 2, 2010, gross profit of the Semiconductor Systems segment decreased by $3.7 million, or 49.1%, from $7.6 million during the three months ended July 3, 2009 to
$3.9 million during the three months ended July 2, 2010, as a result of the recognition of $15.1 million of revenue from orders placed prior to 2009 during the second quarter of 2009, as compared to $0.3 million for the second quarter of 2010.
As a result of higher margins on the $15.1 million revenue recognized during the second quarter of 2009, the Semiconductor System segments gross profit margin decreased in the second quarter of 2010 as compared to the second quarter of 2009.

During the three months ended July 2, 2010, Excel generated $19.9 million of gross profit, or 44.2% of sales, as
compared with $10.7 million of gross profit, or 36.5% of sales, in the three months ended July 3, 2009. The increase in gross profit and gross profit margin was primarily attributable to the 54.7% increase in sales volume as well as a change in
product mix.

Research and Development and Engineering Expenses

Research and development and engineering (R&D) expenses are primarily comprised of labor and other employee-related
expenses. R&D expenses were $7.4 million, or 8.6% of sales, during the three months ended July 2, 2010, compared with $6.9 million, or 10.9% of sales, during the three months ended July 3, 2009. R&D expenses, in terms of total
dollars, increased slightly, and decreased as a percentage of sales primarily due to the increase in sales. We believe the development and market introduction of new products and the enhancement of existing products are essential to our success.
Accordingly, during 2010, we continued to invest in the development of new products across all three of our segments.

Selling, General and Administrative Expenses

Selling, general and administrative (SGA) expenses include costs for sales and marketing, sales administration, finance, human resources, legal,
information systems, facilities and executive management, and includes personnel related costs, commissions, advertising, legal, tax, accounting and other professional fees. SGA expenses were $17.6 million, or 20.5% of sales during the three months
ended July 2, 2010, as compared to $14.6 million during the three months ended July 3, 2009, representing 23.3% of sales. SGA expenses, in terms of total dollars, increased primarily as a result of an increase in overall sales, selling
costs and commissions, and an increase in legal, financial and accounting related consulting and professional fees. We expect to incur consulting and professional fees in connection with the 2010 quarterly and annual financial statements. In
addition, SGA included a charge of $1.0 million during the three months ended July 2, 2010 for severance and stock compensation pursuant to a separation agreement related to the resignation of our former CEO.

Amortization of Purchased Intangible Assets

All amortization of purchased intangible assets is charged to our Precision Technology and Excel segments. Amortization of purchased
intangible assets, excluding the amortization for core technology that is included in cost of goods sold, was $1.1 million, or 1.3% of sales, during the three months ended July 2, 2010, compared with $1.6 million, or 2.5% of sales, during the
three months ended July 3, 2009. The decrease in 2010, in terms of both dollars and as a percentage of sales, was primarily related to certain intangible assets acquired as part of the Excel acquisition becoming fully amortized in the second
half of 2009.

Restructuring, Restatement Related Costs and Other

We recorded restructuring, restatement related costs and other charges of $1.0 million and $3.1 million during the three months ended
July 2, 2010 and July 3, 2009, respectively.

Restructuring

We did not incur any restructuring costs during the three months ended July 2, 2010. During the three months ended July 3, 2009,
we recorded $0.2 million in restructuring costs related to a plan initiated in December 2008, which involved the transfer of all volume related manufacturing from our Rugby, U.K. facility within the Precision Technology segment, to our facilities in
China and the then-newly acquired Excel manufacturing sites. These costs were comprised entirely of employee severance costs.

Restatement Related Costs and Other

During the three months ended July 2, 2010, we incurred costs related to third parties, including auditors, attorneys, forensic accountants, and other advisors, for services performed in connection
with the restatement of our previously issued financial statements as reported in our Form 10-K for the year-ended December 31, 2008 and our Form 10-Q for the quarter ended September 26, 2008, including, the SEC investigation, certain
shareholder actions and the internal FCPA investigation. These costs are charged to expense as incurred and are included in our restructuring, restatement related costs and other charges for the respective periods in the accompanying consolidated
statements of operations. These costs totaled $1.0 million for the three months ended July 2, 2010, primarily related to the SEC investigation, as compared to $2.9 million for the three months ended July 3, 2009, which primarily
related to the SEC and FCPA investigations, and legal and accounting costs associated with our revenue review.

Pre-Petition Professional Fees

Pre-petition professional fees represent retention costs incurred during 2009 prior to the bankruptcy for financial and legal advisors to assist in the analysis of debt restructuring alternatives, as well
as costs incurred by us of financial and legal advisors retained by the noteholders pursuant to certain binding agreements between the two parties. Pre-petition professional fees incurred during the three months ended July 3, 2009 were
$1.3 million, with no comparable amount for the three months ended July 2, 2010. Professional fees incurred during bankruptcy are generally classified as reorganization items as described further below.

Interest Income

Interest income decreased slightly during the three months ended July 2, 2010, as compared to the three months ended July 3, 2009, primarily attributable to decreasing amounts of interest earned
on our outstanding auction rate securities, which have been decreasing due to sales.

Interest Expense

Interest expense related to our $210.0 million debt was $5.7 million during the three months ended July 2, 2010, as compared to $7.1
million during the three months ended July 3, 2009. The $1.4 million decrease in interest expense was primarily attributable to the write-off of our debt discount and deferred financing costs in the fourth quarter of 2009. Prior to the
write-off, these amounts had been amortized to interest expense over the contractual terms of the debt.

Foreign Exchange Transaction Gains (Losses), Net

Foreign exchange currency transaction loss, net, was $0.1 million during the three months ended July 2, 2010 compared to $1.4 million
during the three months ended July 3, 2009. The decrease in losses was due to a stronger U.S. dollar during the 2010 period, as compared to the 2009 period.

Other Income (Expense), Net

Other income (expense), net, was $1.1 million
during the three months ended July 2, 2010, compared to $0.9 million during the three months ended July 3, 2009. The $1.1 million of other income in 2010 is primarily comprised of a $0.7 million gain on the sale of our remaining auction
rate securities and $0.4 million in earnings on our equity investment. The $0.9 million of other income in 2009 is primarily comprised of a $1.7 million gain on the sale of a portion of our auction rate securities and $0.1 million in earnings on our
equity investment, partially offset by a $0.9 million penalty relating to our inability to maintain the effectiveness of the registration statement on Form S-3 that we filed in October 2008 relating to the resale of our common shares issued upon the
exercise of the Warrants.

Reorganization Items

Reorganization items represent expense or income amounts that are recorded in the consolidated financial statements as a result of the
bankruptcy proceedings. Reorganization items, primarily comprised of professional fees totaling $10.6 million, were incurred during the three months ended July 2, 2010, with no comparable amounts for 2009. See Note 2 to Consolidated Financial
Statements.

Income Taxes

The effective tax rate on the loss from continuing operations for the three months ended July 2, 2010, was a provision of 14.4% compared with a benefit of 7.0% on the loss from continuing
operations for the three months ended July 3, 2009. The effective tax rate for the three months ended July 2, 2010 reflects our estimated annual effective tax rate and differs from the Canadian Statutory rate primarily due to the tax
treatment of bankruptcy related costs, income earned in jurisdictions with varying tax rates, and the release of a portion of our valuation allowance.

Income from Discontinued Operations, Net of Tax

On October 8, 2008,
we completed the sale of our U.S. Optics Business, located in Moorpark, California. During the three months ended July 3, 2009, we recorded an additional charge of $0.1 million related to discontinued operations associated with an insurance
premium adjustment.

|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Sales of the various product lines that comprise our
Precision Technology segment increased by $23.4 million, or 64.2%, from $36.4 million during the six months ended July 3, 2009 to $59.8 million during the six months ended July 2, 2010. Sales increased across all product lines that
comprise the Precision Technology segment, except for our printers product line. Sales during the six months ended July 2, 2010 increased compared with the six months ended July 3, 2009, primarily due to higher demand from OEM and other
customers who in turn have experienced an increase in demand for their products due to an improving world economy. The first half of 2009 was a period of particularly weak demand for our products due to the tight credit conditions and low levels of
personal consumption and capital investment that existed at that time. Our product line that supplies drilling components to leading printed circuit board (PCB) drilling manufacturers, which serve a variety of consumer industries
including electronics and automobiles, accounted for approximately $11.2 million of the $23.4 million increase in sales for this segment.

Semiconductor Systems segment sales increased by $26.4 million, or 83.5%, from $31.6 million during the six months ended July 3, 2009 to $58.0 million during the six months ended July 2, 2010.
The increase in Semiconductor Systems sales was primarily attributable to the recognition of $41.0 million of revenue during the first half of 2010 as compared to $26.2 million during the first half of 2009, that had been deferred from orders placed
by customers prior to 2009, but had not been recognized in the period in which shipments occurred due to previously undelivered elements or unresolved commitments. The revenue related to these orders was recognized once the final deliverables or
commitments were resolved. Sales also rebounded during the first half of 2010 due to the increased demand for capital equipment by semiconductor manufacturers. The level of capital expenditures by these customers began rebounding in 2010 from
historically low levels in previous years.

Sales of the various product lines that comprise our Excel segment increased by
$26.3 million, or 43.1%, from $61.1 million during the six months ended July 2, 2009 to $87.4 million for the six months ended July 2, 2010. The increase in sales was primarily attributable to a strong rebound in sales of lasers, scanners
and optics during the six months ended July 2, 2010, as compared to the six months ended July 3, 2009.

Gross profit as a percentage of sales can be influenced by a number of factors including product mix,
pricing, volume, costs for raw materials and outsourced manufacturing, warranty costs and charges related to excess and obsolete inventory, at any particular time.

During the six months ended July 3, 2010, gross profit of the Precision Technology segment increased by $15.1 million, or 108.6%, from $13.9 million during the six months ended July 3, 2009 to
$28.9 million during the six months ended July 2, 2010. The Precision Technology segments gross profit margin was 48.4% during the six months ended July 2, 2010, compared with a gross profit margin of 38.1% during the six months
ended July 3, 2009. Our gross margin, in terms of dollars, improved due to the significant increased demand for our products. The improvement in gross profit margin of our Precision Technology segment was primarily attributable to higher
capacity utilization resulting from the increase in demand for our products, partially offset by an increase in excess and obsolete inventory provisions.

During the six months ended July 2, 2010, gross profit of the Semiconductor Systems segment increased by $9.1 million, or 76.2%, from $11.9 million during the six months ended July 3, 2009 to
$21.0 million during the six months ended July 2, 2010, primarily due to the increase in sales. The Semiconductor System segments gross profit margin was 36.2% during the six months ended July 2, 2010, compared with a gross profit
margin of 37.7% during the six months ended July 3, 2009. The decrease in the Semiconductor Systems segment gross profit margin was primarily attributable to product mix on revenue recognized related to orders placed by customers prior to 2009.
Revenue deferred prior to 2009 and recognized during the six months ended July 3, 2009, had higher gross profit margins as compared to the revenue that was recognized during the first half of 2010.

During the six months ended July 2, 2010, Excel generated $38.6 million of gross profit, or 44.2% of sales, as compared with $23.6
million of gross profit, or 38.6% of sales, in the six months ended July 3, 2009. The increase in gross profit and gross profit margin was primarily attributable to the 43.1% increase in volume of sales as well as a change in product mix,
partially offset by an increase in excess and obsolete inventory provisions.

Research and Development and Engineering
Expenses

Research and development and engineering (R&D) expenses were $14.8 million during the six months
ended July 2, 2010, representing 7.4% of sales, compared with $15.0 million, or 11.8% of sales, during the six months ended July 3, 2009. R&D expenses remained relatively consistent over the periods, and decreased as a percentage of
sales due to the significant increase in sales.

Selling, General and Administrative Expenses

Selling, general and administrative (SGA) expenses include costs for sales and marketing, sales administration, finance, human
resources, legal information systems, facilities and executive management, and includes personnel related costs, commissions, advertising, legal, tax, accounting and other professional fees. SGA expenses were $35.1 million, or 17.6% of sales, during
the six months ended July 2, 2010, compared with $29.4 million, or 23.2% of sales, during the six months ended July 3, 2009. SGA expenses, in terms of total dollars, increased primarily as a result of an increase in overall

sales, selling costs and commissions, and an increase in finance, accounting and other related professional and consulting fees. We expect to incur consulting and professional fees in connection
with the 2010 quarterly and annual financial statements. In addition, SGA included a charge of $1.0 million during the six months ended July 2, 2010 related to severance and stock compensation pursuant to a separation agreement related to the
resignation of our former CEO. SGA decreased as a percentage of sales due to the significant 58.0% increase in sales.

Amortization of Purchased Intangible Assets

All amortization of purchased intangible assets is charged to our Precision Technology and Excel segments. Amortization of purchased intangible assets, excluding the amortization for core technology that
is included in cost of goods sold, was $2.3 million, or 1.1% of sales, during the six months ended July 2, 2010, compared to $3.2 million, or 2.5% of sales, during the six months ended July 3, 2009. The decrease in 2010, in terms of both
dollars and as a percentage of sales, was primarily related to certain intangible assets acquired as part of the Excel acquisition becoming fully amortized in the second half of 2009.

Restructuring, Restatement Related Costs and Other

We recorded restructuring, restatement related costs and other charges of $1.7 million and $11.4 million during the six months ended July 2, 2010 and July 3, 2009, respectively.

Restructuring

We did not incur any restructuring costs during the six months ended July 2, 2010. During the six months ended July 3, 2009, we recorded $0.7 million in restructuring costs related to a plan
initiated in December 2008, which involved the transfer of all volume related manufacturing from our Rugby, U.K. facility within the Precision Technology segment, to our facilities in China and the then-newly acquired Excel manufacturing sites.
These costs were comprised entirely of employee severance costs.

The following table summarizes the balance of the
restructuring accrual on our consolidated balance sheets (in thousands):

Restatement Related Costs and Other

During the six months ended July 2, 2010, we incurred costs related to third parties, including auditors, attorneys, forensic
accountants, and other advisors, for services performed in connection with the restatement of our previously issued financial statements as reported in our Form 10-K for the year-ended December 31, 2008 and our Form 10-Q for the quarter ended
September 26, 2008, including, the SEC investigation, certain shareholder actions and the internal FCPA investigation. These costs are charged to expense as incurred and are included in our restructuring, restatement related costs and other
charges for the respective periods in the accompanying consolidated statements of operations. The costs incurred were $1.7 million during the six months ended July 2, 2010, which primarily related to the SEC investigation, as compared to
$10.7 million incurred during the six months ended July 3, 2009, which primarily related to the SEC and FCPA investigations, and legal and accounting costs associated with our revenue review.

Pre-Petition Professional Fees

Pre-petition professional fees represent costs incurred during 2009 prior to our bankruptcy filing related to the financial and legal advisors retained by us to assist in the analysis of debt
restructuring alternatives, as well as costs incurred by us related to financial and legal advisors retained by the noteholders pursuant to certain binding agreements between the two parties. Pre-petition professional fees incurred during the
six months ended July 3, 2009 were $2.0 million, with no comparable amount during the six months ended July 2, 2010. Professional fees incurred during bankruptcy are generally classified as reorganization items as described further below.

##### Table of Contents

Interest Income

Interest income decreased to $0.1 million during the six months ended July 2, 2010, from $0.2 million during the six months ended
July 3, 2009, primarily attributable to decreasing amounts of interest earned on our outstanding auction rate securities, which have been decreasing due to sales.

Interest Expense

Interest expense related to our $210.0 million debt was
$11.6 million during the six months ended July 2, 2010, as compared to $14.2 million during the six months ended July 3, 2009. The $2.6 million decrease in interest expense was primarily attributable to the write-off of our debt discount
and deferred financing costs in the fourth quarter of 2009. Prior to the write-off, these amounts had been amortized to interest expense over the contractual terms of the debt.

Foreign Exchange Transaction Gains (Losses), Net

Foreign exchange currency transaction gains (losses), net, was $0.3 million during the six months ended July 2, 2010 compared to ($1.3) million during the six months ended July 3, 2009. The
decrease in losses was due to a stronger U.S. dollar during the 2010 period, as compared to the 2009 period.

Other Income
(Expense), Net

Other income (expense), net, was $1.7 million during the six months ended July 2, 2010, compared to
$0.2 million during the six months ended July 3, 2009. The $1.7 million of other income during the six months ended July 2, 2010 is primarily comprised of a $1.0 million gain on the sale of our remaining auction rate securities and $0.6
million in earnings on our equity investment. The $0.2 million of other income during the six months ended July 3, 2009 is primarily comprised of a $1.8 million gain on the sale of a portion of our auction rate securities and $0.2 million in
earnings on our equity investment, partially offset by a $1.8 million penalty relating to our inability to maintain the effectiveness of the registration statement on Form S-3 that we filed in October 2008 relating to the resale of our common shares
issued upon the exercise of the Warrants.

Reorganization Items

Reorganization items represent expense or income amounts that are recorded in the consolidated financial statements as a result of the
bankruptcy proceedings. Reorganization items, primarily comprised of professional fees totaling $20.2 million, were incurred during the six months ended July 2, 2010, with no comparable amounts for 2009. See Note 2 to Consolidated Financial
Statements.

Income Taxes

The effective tax rate on the income from continuing operations for the six months ended July 2, 2010, was a provision of 71.4% compared with a benefit of 5.9% on the loss from continuing
operations for the six months ended July 3, 2009. The effective tax rate for the six months ended July 2, 2010 reflects our estimated annual effective tax rate and differs from the Canadian statutory rate primarily due to the tax treatment
of bankruptcy related costs, income earned in jurisdictions with varying tax rates, and the release of a portion of our valuation allowance.

Liquidity and Capital Resources

On November 20, 2009, GSIG,
together with two of its subsidiaries, voluntarily filed petitions for relief under Chapter 11 of the United States Bankruptcy Code. Accordingly, this debt has been classified as a liability subject to compromise as of July 2, 2010 and
December 31, 2009 in our accompanying consolidated balance sheets. Operating in bankruptcy imposed significant risks and uncertainties on our business.

However, we emerged from bankruptcy on July 23, 2010 and, in connection therewith, completed a rights offering pursuant to which we sold common shares for cash proceeds of approximately $64.9
million. The proceeds from the Rights Offering, together with $10.0 million of cash on hand, were used to pay down $74.9 million of the $210.0 million principal obligations due with respect to the 2008 Senior Notes. The principal obligations on the
2008 Senior Notes were further reduced and settled through the issuance of common shares in exchange for $28.1 million of 2008 Senior Notes. In addition, upon emergence from bankruptcy, we used cash to pay all outstanding accrued interest on the
2008 Senior Notes which totaled $21.7 million.

The remaining $107.0 million obligation due with respect to the 2008 Senior
Notes were satisfied through the issuance of new 12.25% Senior Secured PIK Election Notes which mature in July 2014. Interest accrues on the New Notes at a rate of 12.25% per year and is payable quarterly in arrears on February 15,
May 15, August 15 and November 15 of each

year, commencing on August 15, 2010. GSI US may elect to pay the interest in cash, or, under certain
conditions, by increasing the principal amount of the New Notes or issuing additional notes on the same terms and conditions as the existing New Notes (PIK). Furthermore, until we become current in our reporting obligations under the
Securities Exchange Act of 1934, as amended (the Exchange Act) and until our common shares are listed on an Eligible Market (as defined in the New Indenture), the rate of interest under the New Notes will be increased by an additional
2% per annum, payable by PIK beginning after August 15, 2010. The interest rate on the New Notes may be increased upon certain defaults, as defined in the New Indenture. Interest PIK notes issued and PIK payments in lieu of cash payments
accrue at a rate of 13%. If the New Notes remain outstanding until their scheduled maturity date in 2014, annual interest expense on the New Notes would be approximately $13.2 million per year from 2011 to 2013 and $8.0 million in 2014.

As a result of our emergence from bankruptcy, the associated restructuring of our debt obligations, and our current level of business
activity, we believe we will have sufficient liquidity to fund our operations through at least the end of 2011. However, our ability to make payments on or to refinance our indebtedness, including the New Notes, which incur an additional 2% in
interest until our common shares are listed on a national securities exchange and we become current with our SEC reporting, and to fund planned capital expenditures and research and development efforts will depend on our ability to generate cash in
the future and have access to capital markets. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

We cannot assure you that our business will generate sufficient cash flow from operations, that currently anticipated cost savings and
operating improvements will be realized on schedule or that future borrowings will be available to us in an amount sufficient to enable us to pay our indebtedness, including the New Notes, or to fund our other liquidity needs. We may need to
refinance all or a portion of our indebtedness, including the New Notes on or before their maturity in 2014. Under the terms of the New Indenture, GSI US may obtain a working capital facility of up to $40 million with the consent of the noteholders,
whose consent cannot be unreasonably withheld. To the extent the aggregate principal amount of the outstanding indebtedness under the working capital facility exceeds $20 million, or upon certain asset sales, GSIG or GSI US will be required to offer
to use such excess working capital proceeds or excess net proceeds, as applicable, to make an offer to purchase a portion of the New Notes at 100% of the principal amount thereof. We cannot assure you that we will be able to refinance any of our
indebtedness, including the New Notes, on commercially reasonable terms or at all.

Although much of our business is conducted
through our subsidiaries, none of our subsidiaries is obligated to make funds available to us. Accordingly, our ability to make payments on our indebtedness and fund our operations may be dependent on the earnings and the distribution of funds from
our subsidiaries. Local laws and regulations and/or the terms of the indenture governing the New Notes may restrict certain of our subsidiaries from paying dividends and otherwise transferring assets to us. We cannot assure you that applicable laws
and regulations and/or the terms of the indenture will permit our subsidiaries to provide us with sufficient dividends, distributions or loans when necessary.

Cash and cash equivalents totaled $87.4 million at July 2, 2010, compared to $63.3 million at December 31, 2009. The increase in cash and cash equivalents is primarily related to stronger sales
and improvements in collections, proceeds totaling $11.4 million received from the sale of our remaining auction rate securities, and tax refunds totaling $1.8 million.

Also, while operating in bankruptcy, we deferred our interest payments on the 2008 Senior Notes until emergence from bankruptcy on July 23, 2010. Accrued interest totaled $20.2 million and $8.6
million in the aggregate on our accompanying consolidated balance sheets as of July 2, 2010 and December 31, 2009, respectively. We did not make any interest payments during the six months ended July 2, 2010, compared with payments of
$11.3 million during the six months ended July 3, 2009. See Notes 1, 2, 6, and 15 to Consolidated Financial Statements for further information about the 2008 Senior Notes.

Cash Flows for Six Months Ended July 2, 2010 and July 3, 2009

Cash provided by operating activities during the six months ended July 2, 2010 was $14.5 million, compared to cash used in operating
activities of $21.2 million during the six months ended July 3, 2009, an increase of $35.7 million. The increase in cash provided by operating activities was primarily attributable to the following factors:



| |  |  | During the six months ended July 2, 2010, we recorded net income of $1.0 million, compared with a loss of $26.6 million during the six months
ended July 3, 2009, an increase of $27.6 million before non-cash adjustments to reconcile net income (loss) to net cash provided by (used in ) operating activities.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Non-cash adjustments to reconcile net income (loss) to cash provided by (used in) operating activities included the following material items:
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Depreciation and amortization charges of $7.5 million during the six months ended July 2, 2010, compared with $9.3 million during the six months
ended July 3, 2009, decreased due to certain fixed assets becoming fully depreciated and certain intangibles becoming fully amortized during 2009.

Other Liquidity Matters

Debt

On August 20, 2008 (the Closing Date), we issued to various investors $210.0 million of Senior Notes due 2013 pursuant to the terms of an indenture (the 2008 Senior Note
Indenture), along with detachable warrants (the Warrants) for the purchase of 5,882,520 of our common shares, for collective net proceeds of $203.5 million. The proceeds were used to fund a portion of our acquisition of Excel.

##### Table of Contents

The 2008 Senior Notes pay interest semi-annually on
February 15thand August 15thand mature in August 2013. The 2008 Senior Note Indenture contained
covenants that restricted our ability to incur additional indebtedness, pay dividends, create liens, make investments, sell assets, repurchase securities, or engage in specified transactions with affiliates. As discussed in Note 1 to Consolidated
Financial Statements, GSIG and two of its wholly-owned United States subsidiaries filed for bankruptcy on November 20, 2009. Accordingly, the 2008 Senior Notes are classified as a liability subject to compromise in our accompanying consolidated
balance sheets as of July 2, 2010 and December 31, 2009. As described in Note 15 to Consolidated Financial Statements, the 2008 Senior Notes were cancelled upon our emergence from bankruptcy in exchange for the issuance of our common
shares, New Notes, and a payment in cash.

Also, while operating in bankruptcy, we deferred our interest payments on the 2008
Senior Notes until emergence from bankruptcy on July 23, 2010. Accrued interest totaled $20.2 million and $8.6 million in the aggregate on our accompanying consolidated balance sheets as of July 2, 2010 and December 31, 2009,
respectively. We did not make any interest payments during the six months ended July 2, 2010, compared with payments of $11.3 million during the six months ended July 3, 2009. See Notes 1, 2, 6, and 15 to Consolidated Financial Statements
for further information about the 2008 Senior Notes.

Pension Plans

We maintain two plans that are considered to be defined benefit plans under the provisions of ASC 715, Defined Benefit Plans,
a plan in the U.K. (the U.K. Plan), and a plan in Japan. Our U.K. Plan was closed to new members in 1997 and we curtailed our sponsorship in 2002, thereby limiting our obligation to benefits earned through that date. Benefits under this
plan were based on the employees years of service and compensation. We continue to follow our policy to fund this pension plan based on widely accepted actuarial methods. Our Japanese plan is an active plan.

Our funding policy is to fund pensions and other benefits based on actuarial methods as permitted by regulatory authorities. The results
of funding valuations depend on the assumptions that we make with regard to attributes such as asset returns, rates of members benefits increases, mortality, retail price inflation and other market driven changes. The assumptions used
represent one estimate of a possible future outcome. The final cost to us will be determined by events as they actually become known. Because of the underfunded positions that our pension plans currently have and potential changes in the actual
outcomes relative to our assumptions, we may have to increase payments to fund these plans in the future.

In the U.K.,
funding valuations are conducted every three years. Based on the last completed funding valuation on November 30, 2006, we and the Plan Trustees agreed to a schedule of contributions under which we are contributing approximately $0.6 million
per year until 2018. Based on the results of a new funding valuation completed in 2010, we increased our annual contributions to the U.K. Plan from approximately $0.6 million to $0.8 million for a period of 10 years and 5 months beginning September
2010, including an additional one-time lump-sum payment of approximately $1.6 million, of which $0.8 million was paid in September 2010 and $0.8 million was paid in December 2010. The Japanese plan includes a guarantee of return of principal and
yearly interest 0.75%; therefore, there are no significant fluctuations in this plan. See Notes 9 and 15 to Consolidated Financial Statements for further information about these plans.

As a result of the covenant that exists between our U.K. subsidiary and the Plan Trustees regarding the funding of the U.K. Plan, our
ability to transfer assets outside our U.K. subsidiary, and its wholly owned subsidiary in China, may be limited.

Off-Balance Sheet Arrangements, Contractual Obligations

Contractual Obligations

Historically, our contractual obligations have primarily consisted of the 2008 Senior Notes, operating leases, purchase commitments and pension obligations. Through July 2, 2010, we had not entered
into any new material or modified contractual obligations since the end of the fiscal year ended December 31, 2009, with the exception of the lease modification discussed below.

In February 2010, we amended the lease agreement covering our corporate headquarters in Bedford, Massachusetts. The lease amendment
became effective upon confirmation of our Final Chapter 11 Plan on May 27, 2010. Under the terms of the amended lease, the lease will expire on May 27, 2013 unless terminated early. The landlord has the right to terminate the lease upon
nine months written notice, but not earlier than June 1, 2011. In the aggregate, the modification reduces our obligations under the current lease by approximately $10.8 million, of which $0.9 million relates to 2013, $1.6 million relates to
2014 and $8.3 million relates to periods thereafter.

Off-Balance Sheet Arrangements

Through July 2, 2010, we had not
entered into any off-balance sheet arrangements or material transactions with unconsolidated entities or other persons.

Critical Accounting Policies and Estimates

The critical accounting policies that we believe impact significant judgments and estimates used in the preparation of our consolidated financial statements presented in this report are described in our
Managements Discussion and Analysis of Financial Condition and Results of Operations and in the Notes to Consolidated Financial Statements, each included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009, filed
with the SEC on October 1, 2010.

Recent Accounting Pronouncements

See Note 3 to Consolidated Financial Statements for recent accounting pronouncements that could have an effect on us.



|Item 3. | Quantitative and Qualitative Disclosures about Market Risk
|------- | ----------------------------------------------------------

Our primary market risk exposures are foreign currency exchange rate fluctuation and interest rate sensitivity. During the six months ended July 2, 2010, there have been no material changes to the
information included under 7A Quantitative and Qualitative Disclosures About Market Risk, in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009, filed with the SEC on October 1, 2010.



|Item 4. | Controls and Procedures
|------- | -----------------------

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15 under the Exchange Act, our management carried out an evaluation, with the participation of our Principal Executive Officer and Principal Financial Officer, of the effectiveness
of our disclosure controls and procedures, as of July 2, 2010, the end of the period covered by this report. Based upon this evaluation, our Principal Executive Officer and Principal Financial Officer have concluded that our disclosure controls
and procedures (as defined in Rule 13a-15(e) of the Exchange Act) were not effective as of July 2, 2010 to provide reasonable assurance that information required to be disclosed by us, in the reports that we file or submit under the Exchange
Act is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms, and that such information is accumulated and communicated to our management, including the Principal Executive Officer and
Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure, because of the following material weaknesses in our internal control over financial reporting, which is more fully described in Item 9A of our
Annual Report on Form 10-K for the fiscal year ended December 31, 2009 and incorporated by reference herein, which have not been remediated as of July 2, 2010:



| |  |  | Inadequate and ineffective controls over the corporate financial statement close process
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | Inadequate and ineffective controls over the recognition of Semiconductor Systems revenue
| | - |  | -----------------------------------------------------------------------------------------

Changes in Internal Control Over Financial Reporting

We are taking corrective actions to remediate the material weaknesses listed above, including remediation actions described in
Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 and incorporated by reference herein. However, as of July 2, 2010, we have not completed the remediation of the above material weaknesses.

Other than as noted above, there has been no change in our internal control over financial reporting that occurred during our
fiscal quarter ended July 2, 2010 that has materially affected, or is reasonably likely to materially affect, such internal control over financial reporting.

PART IIOTHER INFORMATION



|Item 1. | Legal Proceedings
|------- | -----------------

The
Companys French subsidiary, GSI Lumonics SARL (Lumonics), is subject to a claim by a customer, SCGI, that a Laserdyne 890 system delivered in 1999 had unresolved technical problems. During the third quarter of 2005, GSI France,
parent of Lumonics, filed for bankruptcy protection, which was granted by the French court on July 7, 2005. On April 18, 2006, the court fixed SCGIs claim against Lumonics at 598,079, plus court costs and expert fees of
85,945. SCGI accepted the courts determination and demanded that the Liquidator bring an action in the United Kingdom against GSI Group Ltd., the parent corporation of GSI France. The Company does not believe it will be required to make
any payments regarding this action. Accordingly, nothing has been accrued in the Companys accompanying consolidated financial statements with respect to this claim.

On December 12, 2008, in connection with the delayed filing of its results for the quarter ended September 26, 2008, and the announcement of a review of revenue transactions, a putative
shareholder class action alleging federal securities violations was filed in the United States District Court for the District of Massachusetts against the Company, a former officer and a then current officer and director. Specifically, the
complaint alleges that the Company and the individual defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, and seeks recovery of damages in an unspecified amount. A lead
plaintiff, Mason Tenders District Council Trust Funds, was appointed on May 8, 2009. In May 2010, the parties reached an agreement in principle to settle the litigation. The settlement covers purchasers of the common stock of the Company
between February 27, 2007 and June 30, 2009. On October 12, 2010, the United States District Court approved an order granting the parties Motion for Certification of a Settlement Class and for Preliminary Approval of Class
Action Settlement. The United States District Court has set February 16, 2011 as the date for the final Settlement Fairness Hearing. Although the settlement agreement has not yet been approved by the United States District Court, the total
settlement amount has been deposited into an escrow account. If the settlement is approved by the United States District Court, the Companys contribution to the settlement amount will be limited to the balance of the Companys
self-insured retention.

The Company is also subject to various legal proceedings and claims that arise in the ordinary course
of business. The Company does not believe that the outcome of these claims will have a material adverse effect upon its financial condition or results of operations but there can be no assurance that any such claims, or any similar claims, would not
have a material adverse effect upon its financial condition or results of operations.

Chapter 11 Cases

Certain creditor claims filed in connection with the Companys Final Chapter 11 Plan remain subject to final
resolution.

On April 8, 2010, the Internal Revenue Service (IRS) filed amended proofs of claim aggregating
approximately $7.7 million. On July 13, 2010, the Company filed a complaint, GSI Group Corporation v. United States of America, in Bankruptcy Court to recover refunds totaling approximately $18.8 million in federal income taxes
the Company overpaid to the IRS relating to tax years 2000 through 2008, together with applicable interest. The complaint includes an objection to the IRS proofs of claim which the Company believes are not allowable claims and should be
expunged in their entirety.

On May 13, 2010, the Securities and Exchange Commission (SEC) filed a proof of
claim in an indeterminate amount for penalties, disgorgement, and prejudgment interest arising from possible violations of the federal securities laws. As noted below, the SEC has been conducting a formal investigation into certain pre-bankruptcy
transactions and practices involving the Company and sent a Wells Notice to the Company on September 16, 2010. Based on their investigation, the SEC indicated in their proof of claim that they may file a civil action against the
Company in an appropriate forum. The Company is unable to predict the outcome of this matter but, as noted below, the Company is cooperating fully with the SECs investigation.

In addition, under the terms of the Final Chapter 11 Plan, the Company is obligated to make additional payments to the holders of 2008
Senior Notes claims in its Chapter 11 Cases if the amount of certain claims under the Final Chapter 11 Plan exceeds $22.5 million. The additional payment, if any, would equal approximately $1.00 for each dollar by which the $22.5 million cap amount
is exceeded. The Company cannot make a final determination of the amount, if any, the Company may owe as a result of this provision until certain claims filed in connection with its Chapter 11 Cases, including the IRS and SEC claims described above,
are finally resolved. The amount of such claims, based on the known and estimated amount of such claims, is currently well below the $22.5 million cap amount. As the Company does not believe it is probable that its losses under these claims will
exceed $22.5 million, nothing has been accrued in the Companys accompanying consolidated financial statements with respect to this potential obligation.

SEC Investigation

On May 14, 2009, the Company received a notice from the SEC indicating that the SEC is conducting a formal investigation relating to
its historical accounting practices and the restatement of its historical consolidated financial statements. On September 16, 2010, the Company received a Wells Notice from the SEC, stating that the Staff is considering recommending
that the Commission institute a civil injunctive action or administrative proceeding against the Company, alleging that the Company violated various provisions of the Securities Act and the Securities Exchange Act, and providing the Company with the
opportunity to make a submission to the Staff in connection therewith. In connection with the contemplated action, the SEC may seek a permanent injunction or cease-and-desist order, disgorgement, prejudgment interest and the imposition of a civil
penalty. The Company is cooperating fully with the SECs investigation.
