NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(1) Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of 3D Systems Corporation and its subsidiaries (collectively, the “Company”). All significant intercompany transactions and balances have been eliminated in consolidation. The unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) applicable to interim reports. Accordingly, they do not include all the information and notes required by GAAP for complete financial statements and should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K (“Form 10-K”) for the year ended December 31, 2011.

In the opinion of management, the unaudited condensed consolidated financial statements contain all adjustments, consisting of adjustments of a normal recurring nature, necessary to present fairly the financial position, results of operations and cash flows for the periods presented. The results of operations for the three months ended March 31, 2012 are not necessarily indicative of the results to be expected for the full year.

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from those estimates and assumptions.

The Company’s Board of Directors approved a two-for-one stock split, effected in the form of a 100% stock dividend, which was paid on May 18, 2011 to stockholders of record at the close of business on May 9, 2011. The Company’s stockholders received one additional share of common stock for each share of common stock owned. This did not change the proportionate interest that a stockholder maintained in the Company. All share and per share amounts set forth in this report, including earnings per share and the weighted average number of shares outstanding for basic and diluted earnings per share, for each respective period have been adjusted to reflect the two-for-one stock split.

All amounts presented in the accompanying footnotes are presented in thousands, except for per share information.

The Company has evaluated subsequent events from the date of the condensed consolidated balance sheet through the date of the filing of this Form 10-Q. During this period, the Company closed the acquisitions of Fresh Fiber B.V., My Robot Nation and Paramount Industries. See Note 2 and Note 16 for a description of subsequent events.

Recent Accounting Pronouncements

In May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”).” ASU 2011-04 explains how to measure fair value and intends to improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. GAAP and IFRS. ASU 2011-04 became effective prospectively for interim and annual reporting periods beginning on or after December 15, 2011; early adoption was not permitted for public entities. The standard became effective for the Company in January 2012 and did not have a significant impact on the Company’s consolidated financial statements.

In September 2011, the FASB issued ASU 2011-8, “Intangibles – Goodwill and Other (Topic 350).” ASU 2011-8 is intended to simplify the testing of goodwill for impairment by permitting an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350. ASU 2011-8 became effective for fiscal years beginning after December 15, 2011, with early adoption permitted in limited circumstances. The standard became effective for the Company in January 2012 and did not have a significant impact on the Company’s consolidated financial statements.

In December 2011, the FASB issued ASU 2011-12, “Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassification of Items Out of Accumulated Other Comprehensive Income in ASU 2011-5.” ASU 2011-12 defers the effective date pertaining to reclassification adjustments out of accumulated other comprehensive income in ASU 2011-5. Entities should continue to report reclassification adjustments out of accumulated other comprehensive income consistent with the presentation requirements before ASU 2011-5. All other requirements in ASU 2011-5 are not affected by this Update, including the requirement to report comprehensive income either in a single continuous financial statement or in two separate but consecutive financial statements. The standard became effective for the Company in January 2012 and did not have a significant impact on the Company’s consolidated financial statements.

7

No other new accounting pronouncements issued or effective during the first quarter of 2012 have had or are expected to have a significant impact on the Company’s consolidated financial statements.

(2) Acquisitions

The Company completed acquisitions in the first quarter of 2012, which are discussed below.

On January 3, 2012, the Company acquired the shares of Z Corporation (“Z Corp”) and Vidar Systems Corporation (“Vidar”), located in Burlington, MA and Herndon, VA, respectively. Z Corp is a provider of personal and professional 3D printers, 3D scanners, proprietary print materials and printer services. Z Corp’s operations have been integrated into the Company and are included in printers and other products and services revenue. Vidar is a provider of medical film scanners that digitize film for radiology, oncology, mammography and dental applications. Vidar’s operations have been integrated into the Company and included in printers and other products revenue. The fair value of the consideration paid for this acquisition was $134,918, net of cash acquired, all of which was paid in cash, and was allocated to the assets purchased and liabilities assumed based on their estimated fair values as of the acquisition date, and is included in the table below which summarizes first quarter 2012 acquisitions. The Company’s purchase price allocations are preliminary and subject to revision as more detailed analyses are completed and additional information about fair value of assets and liabilities becomes available.

The amounts related to the acquisitions of these businesses were allocated to the assets acquired and the liabilities assumed and included in the Company’s condensed consolidated balance sheet at March 31, 2012 as follows:

(in thousands)	2012
Fixed assets	$	5,318
Goodwill		96,002
Other intangible assets		44,781
Other assets, net of cash acquired and liabilities assumed		(11,183	)
Net assets acquired	$	134,918

The acquisition of Z Corp and Vidar was a significant acquisition, which we previously filed proforma financial information. Revenue for Z Corp and Vidar for the first quarter of 2012 was $12,430 and the operating loss was $212, after taking into account the integration and severance costs.

Subsequent acquisitions

In April, 2012, the Company acquired the outstanding shares of Fresh Fiber B.V. (“Fresh Fiber”). Fresh Fiber designs and markets innovative 3D printed accessories for retail consumer electronics. The Company plans to integrate Fresh Fiber into its consumer solutions services and future revenue from this acquisition will be reported in services revenue. The fair value of the consideration paid for this acquisition, net of cash acquired was $1,307, based on the exchange rate at the date of acquisition, of which $915 was paid in cash and $392 was paid in shares of the Company’s common stock. These shares were issued in a private transaction exempt from registration under the Securities Act of 1933. Due to the timing of this acquisition, the Company is in the process of allocating the fair values of the assets purchased, liabilities assumed and other intangibles identified as of the acquisition date, with any excess to be recorded as goodwill. The Company plans to integrate Fresh Fiber into consumer solutions and future revenue from this acquisition will be reported in services revenue. The Fresh Fiber acquisition is not significant to the Company’s financial statements.

Subject to the terms and conditions of the acquisition agreement, the seller has the right to earn an additional amount pursuant to an earnout formula over a three-year period as set forth in the acquisition agreement, up to a maximum of $2,614, based on the exchange rate at the date of acquisition.

In April 2012, the Company acquired Kodama Studios, LLC, which operates My Robot Nation (“My Robot Nation”), a consumer technology platform that provides intuitive, game-like content creation for 3D printing. The fair value of the consideration paid for this acquisition, net of cash acquired was $2,750, of which $1,500 was paid in cash and $1,250 was paid in shares of the Company’s common stock. These shares were issued in a private transaction exempt from registration under the Securities Act of 1933. Due to the timing of this acquisition, the Company is in the process of allocating the fair values of the assets purchased, liabilities assumed and other intangibles identified as of the acquisition date, with any excess to be recorded as goodwill. The Company plans to integrate My Robot Nation into Cubify.com and future revenue from this acquisition will be reported in services revenue. The My Robot Nation acquisition is not significant to the Company’s financial statements.

In April 2012, the Company acquired the assets of Paramount Industries (“Paramount”), a direct rapid manufacturing provider of product development solutions for aerospace and medical device applications, from design to production of certified end-use parts and products. The fair value of the consideration paid for this acquisition, net of cash acquired was $7,400, of which $5,550 was paid in cash and $1,850 was paid in shares of the Company’s common stock. These shares were issued in a private transaction exempt from registration under the Securities Act of 1933. Due to the timing of this acquisition, the Company is in the process of allocating the fair values of the assets purchased, liabilities assumed and other intangibles identified as of the acquisition date, with any excess to be recorded as goodwill. The Company plans to leverage Paramount for rapid manufacturing, tooling and assembly operations facilities as part of its on-demand parts services primarily for aerospace, defense and medical device applications and future revenue from this acquisition will be reported in services revenue. The Paramount acquisition is not significant to the Company’s financial statements.

Subject to the terms and conditions of the acquisition agreement, the seller has the right to earn an additional amount pursuant to an earnout formula over a five-year period as set forth in the acquisition agreement. In connection with the acquisition the Company entered into a lease agreement with the former owner of Paramount Industries pursuant to which the Company agreed to lease the facilities at which Paramount Industries conducts its operations. The lease provides for an initial term of five years, with options for two successive three-year terms.

(7) Hedging Activities and Financial Instruments

The Company conducts business in various countries using both the functional currencies of those countries and other currencies to effect cross border transactions. As a result, the Company is subject to the risk that fluctuations in foreign exchange rates between the dates that those transactions are entered into and their respective settlement dates will result in a foreign exchange gain or loss. When practicable, the Company endeavors to match assets and liabilities in the same currency on its balance sheet and those of its subsidiaries in order to reduce these risks. When appropriate, the Company enters into foreign currency contracts to hedge exposures arising from those transactions. The Company has elected not to prepare and maintain the documentation to qualify for hedge accounting treatment under ASC 815, “Derivatives and Hedging,” and therefore, all gains and losses (realized or unrealized) are recognized in “Interest and other expense (income), net” in the condensed consolidated statements of operations and comprehensive income. Depending on their fair value at the end of the reporting period, derivatives are recorded either in prepaid expenses and other current assets or in accrued liabilities on the condensed consolidated balance sheet.

There were no foreign currency contracts outstanding at March 31, 2012 or December 31, 2011.

10

The total impact of foreign currency transactions on the condensed consolidated statements of operations and comprehensive income for the three months ended March 31, 2012 reflected a gain of $520 compared to a gain of $555 for the three months ended March 31, 2011.

(8) Borrowings

5.5% senior convertible notes and interest expense

In November 2011, the Company issued $152,000 of 5.50% senior convertible notes due in December 2016. These notes are senior unsecured obligations and rank equal in right of payment with all the Company’s existing and future senior unsecured indebtedness. They are also senior in right of payment to any subordinated indebtedness that the Company may incur in the future.

The notes accrue interest at the rate of 5.50% per year payable in cash semi-annually on June 15 and December 15 of each year, beginning June 15, 2012.

The following table summarizes the principal amounts and related unamortized discount on convertible notes at March 31, 2012 and December 31, 2011:

(in thousands)	2012			2011
Principal amount of convertible notes	$	152,000		$	152,000
Unamortized discount on convertible notes		(20,058	)		(20,893	)
Net carrying value	$	131,942		$	131,107

These notes are convertible into shares of the Company’s Common Stock at an initial conversion rate equivalent to 46.6021 shares of Common Stock per $1 principal amount of notes, which represents an initial conversion rate of approximately $21.46 per share of Common Stock. The conversion rate is subject to adjustment in certain circumstances as more fully set forth in the indenture covering the notes. If converted, the aggregate principal amount of the notes then outstanding may be settled in cash, shares of common stock, or a combination thereof, at the Company’s election. Subject to the terms of the indenture, holders may convert their notes at any time. The number of shares of common stock the notes are currently convertible into is approximately 7,084. In certain circumstances provided for in the indenture, the number of shares of common stock issuable upon conversion of the notes may be increased, and with it the aggregate principal amount of the notes. Unless earlier repurchased, redeemed or converted, the notes will mature on December 15, 2016.

The notes were issued with an effective yield of 5.96% based upon an original issue discount at 98.0%. The net proceeds from the issuance of these Notes, after deducting original issue discount and capitalized issuance costs of $6,634, amounted to $145,366. The capitalized issuance costs are being amortized to interest expense over the life of the notes.

Upon certain terms and conditions, the Company may elect to satisfy its conversion obligation with respect to the notes by paying cash, in whole or in part, for specified aggregate principal amount of the notes. In the event of certain types of fundamental changes, the Company will increase the conversion rate by a number of additional shares, up to a maximum of 9,031 shares, which equates to a conversion price of approximately $16.83 per share.

(9) Stock-based Compensation Plans

The Company records stock-based compensation expense in selling, general and administrative expenses in the condensed consolidated statements of operations and other comprehensive income. Stock-based compensation expense for the three months ended March 31, 2012 and 2011 was as follows:

	Three Months Ended March 31,
(in thousands)	2012		2011
Restricted stock awards	$	1,176	$	387

11

The number of shares of restricted common stock awarded and the weighted average fair value per share during the three-month periods ended March 31, 2012 and 2011 were as follows:

	Three Months Ended March 31,
	2012				2011
(in thousands, except per share amounts)	Shares Awarded		Weighted Average Fair Value		Shares Awarded		Weighted Average Fair Value
Restricted stock awards:
Granted under the 2004 Incentive Stock Plan		93	$	22.40		92	$	15.82
Granted under the 2004 Restricted Stock Plan for Non-Employee Directors		—		—		—		—
Total restricted stock awards		93	$	22.40		92	$	15.82

In the quarter ended March 31, 2012, the Company granted restricted stock awards covering 93 shares of common stock pursuant to the Company’s 2004 Incentive Stock Plan. Of the 93 shares granted in the first quarter of 2012, none of the shares were awarded to executive officers of the Company. Additionally, of the 93 shares granted in the first quarter of 2012, all remained subject to acceptance at March 31, 2012. In the first quarter of 2011, the Company granted restricted stock awards covering 92 shares of common stock pursuant to the Company’s 2004 Incentive Stock Plan; no shares were awarded to executive officers of the Company.

In the first quarters of 2012 and 2011, the Company did not issue any shares of common stock pursuant to the Company’s 2004 Restricted Stock Plan for Non-Employee Directors; therefore, there was no stock compensation expense for Non-Employee Directors the first quarters of 2012 or 2011.

(10) International Retirement Plan

The following table shows the components of net periodic benefit costs and other amounts recognized in the condensed consolidated statements of operations and comprehensive income for the three months ended March 31, 2012 and 2011:

	Three Months Ended March 31,
(in thousands)	2012		2011
Service cost	$	19	$	14
Interest cost		33		16
Total	$	52	$	30

(11) Earnings Per Share

The Company presents basic and diluted earnings per share (“EPS”) amounts. Basic EPS is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the applicable period. Diluted EPS is calculated by dividing net income by the weighted average number of common and common equivalent shares outstanding during the applicable period.

The following table reconciles basic weighted average outstanding shares to diluted weighted average outstanding shares at March 31, 2012 and 2011:

(shares in thousands)	2012		2011
Numerator:
Net income — numerator for basic net earnings per share	$	6,188	$	6,822
Add: Effect of dilutive securities
Stock options and other equity compensation		—		—
Numerator for dilutive earnings per share	$	6,188	$	6,822
Denominator:
Weighted average shares — denominator for basic net earnings per share		50,878		47,587
Add: Effect of dilutive securities
Stock options and other equity compensation		848		1,056
Denominator for dilutive net earnings per share		51,726		48,643
Earnings per share
Basic	$	0.12	$	0.14
Diluted	$	0.12	$	0.14
Unexercised employee stock options excluded from diluted earnings per share (1)		—		—

⁽¹⁾  The average outstanding diluted shares calculation excludes options with an exercise price that exceeds the average market price of shares during the period, since the effect of their inclusion would have been anti-dilutive resulting in an increase to the net earnings per share. The average outstanding diluted shares calculation also excludes shares that may be issued upon conversion of the outstanding senior convertible notes because their conversion price exceeded the weighted average market price during the first quarter of 2012.

For the three months ended March 31, 2012, average common shares for basic and diluted earnings per share were 50,878 and 51,726, respectively, and basic and diluted earnings per share were $0.12. For the three months ended March 31, 2011, average common shares for basic and diluted earnings per share were 47,587 and 48,643 respectively, and basic and diluted earnings per share were $0.14.

(12) Fair Value Measurements

ASC 820, “Fair Value Measurements and Disclosures,” defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs that may be used to measure fair value:

Level 1—Quoted prices in active markets for identical assets or liabilities;

Level 2—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

For the Company, the above standard applies to cash equivalents and senior convertible notes. The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

Assets and liabilities measured at fair value on a recurring basis are summarized below:

	Fair Value Measurements as of March 31, 2012
(in thousands)	Level 1		Level 2		Level 3		Total
Description
Cash equivalents (1)	$	24,982	$	—	$	—	$	24,982

⁽¹⁾ Cash equivalents include funds held in money market instruments and are reported at their current carrying value which approximates fair value due to the short-term nature of these instruments and are included in cash and cash equivalents in the consolidated balance sheet.

The carrying value of the senior convertible notes as of March 31, 2012 and December 31, 2011 was $131,942 and $131,107, respectively, net of the unamortized discount. As of March 31, 2012 and December 31, 2011, the estimated fair value of the senior convertible notes was $150,606 and $149,615, respectively, based on quoted market prices. The Company determined the fair value of the convertible notes utilizing transactions in the listed markets for identical or similar liabilities. As such, the fair value of the senior convertible notes is considered Level 2.

The Company did not have any transfers of assets and liabilities between Level 1 and Level 2 of the fair value measurement hierarchy during the three months ended March 31, 2012.

In addition to the financial assets included in the above table, certain of our non-financial assets and liabilities are to be initially measured at fair value on a non-recurring basis. This includes items such as non-financial assets and liabilities initially measured at fair value in a business combination (but not measured at fair value in subsequent periods) and non-financial, long-lived assets measured at fair value for an impairment assessment. In general, non-financial assets and liabilities including goodwill, other intangible assets and property and equipment are measured at fair value when there is an indication of impairment and are recorded at fair value only when impairment is recognized. The Company has not recorded any impairments related to such assets and has had no other significant non-financial assets or non-financial liabilities requiring adjustments or write-downs to fair value as of March 31, 2012 or December 31, 2011.

(13) Income Taxes

The Company’s effective tax rates were 15.1% and 11.5% for the three months ended March 31, 2012 and March 31, 2011, respectively.

The Company has utilized a portion of its U.S. net deferred tax assets, against which there is a valuation allowance, in determining its effective tax rate for 2012. The remainder of its U.S. net deferred tax assets, against which there are valuation allowances, has been offset by the recognition of deferred income tax liabilities from the acquisition of Z Corp and Vidar. This acquisition resulted in recognizing $502 of deferred income tax assets and $17,701 of deferred income tax liabilities.

13

In conjunction with the Company’s ongoing review of its actual results and anticipated future earnings, the Company assesses the possibility of releasing the valuation allowance remaining on its U.S. net deferred tax assets. There were no releases of the valuation allowance on deferred tax assets during the first quarter of 2012; however, the Company’s effective tax rate has been reduced as a result of the use of U.S. net deferred tax assets against which there is a valuation allowance. As of March 31, 2012, the Company has a valuation allowance remaining on its U.S. net deferred tax assets of $8,549.

Tax years 2008 to 2011 remain subject to examination by the U.S. Internal Revenue Service. The Company has utilized a portion of its U.S. loss carryforwards covering the years 1997 through 2003. Should the Company utilize any of its remaining losses, which date back to 2003, these would be subject to examination. The Company files income tax returns (which are open to examination beginning in the year shown in parentheses) in France (2005), Germany (2007), Japan (2006), Italy (2006), Switzerland (2006), the United Kingdom (2008), the Netherlands (2006), India (2011) and Australia (2007).

(14) Segment Information

The Company operates in one reportable business segment. The Company conducts its business through subsidiaries in the United States, a subsidiary in Switzerland that operates a research and production facility, and sales and services offices, including custom parts services, operated by subsidiaries in Europe (France, Germany, the United Kingdom, Italy and the Netherlands) and in Asia-Pacific (Australia, China and Japan). The Company has historically disclosed summarized financial information for the geographic areas of operations as if they were segments in accordance with ASC 280, “Segment Reporting.”

See Note 2 for details of acquisitions and related commitments.

Litigation

In 2008, DSM Desotech Inc. filed a complaint, which it has subsequently amended, in an action titled DSM Desotech Inc. v. 3D Systems Corporation and 3D Systems, Inc. in the United States District Court for the Northern District of Illinois (Eastern Division) asserting that the Company engaged in anticompetitive behavior with respect to resins used in certain of its stereolithography machines. The complaint further asserted that the Company is infringing upon two of DSM Desotech’s patents relating to stereolithography machines.

The Company filed answers to DSM Desotech’s complaint in which, among other things, the Company denied the material allegations of DSM Desotech’s complaint. In 2010, the Court issued a decision relating to the construction of the claims of the patents-in-suit following a Markman hearing held in 2009. In that decision, the Court generally adopted the claim constructions that the Company proposed.

Fact discovery, including expert discovery, regarding the claims pending in this case concluded in 2011. The Company filed motions for summary judgment in December 2011 that seek rulings in its favor on all of DSM Desotech’s claims in the litigation. As of the date of this Form 10-Q, the Court has not yet ruled on those motions.

The Company understands that DSM Desotech estimates the damages associated with its claims to be in excess of $40,000. The Company intends to continue to vigorously contest all the claims asserted by DSM Desotech.

15

The Company has been pursuing patent infringement litigation against EnvisionTEC, Inc. and certain of its related companies since 2005. In this litigation, the Company asserted that EnvisionTEC infringed the Company’s patents covering various three-dimensional solid imaging products and methods for creating physical three-dimensional models of an object and has sought injunctive relief and damages. EnvisionTEC’s Perfactory machine and Vanquish machine (the Vanquish is now marketed as the PerfactoryXede and PerfactoryXtreme) are the two products accused of patent infringement.

In 2008 the Court issued Markman claim constructions that generally adopted the claim constructions the Company proposed. Following a subsequent jury trial and certain other proceedings, the Court issued a judgment, as amended through 2011, to the effect that EnvisionTEC’s Perfactory and Vanquish machines infringe certain claims of one of our patents and its Vanquish machines infringe certain claims of another of our patents.

On October 13, 2011, EnvisionTEC’s motion to stay damages discovery was denied by the Court, and damages discovery is underway. The Company intends to pursue its claims for damages against EnvisionTEC.

On October 17, 2011, EnvisionTEC filed a Notice of Appeal with the United States Court of Appeals for the Federal Circuit seeking judicial review of the Court’s judgment, and the Company filed a motion to dismiss that appeal on December 12, 2011. As of the date of this Form 10-Q, the Court of Appeals has not yet ruled.

In 2010, MSK K.K., a Japanese company, filed a complaint against the Company’s Japanese subsidiary in the Tokyo District Court asserting, among other things, various contract claims associated with two laser sintering machines purchased from the Company’s Japanese subsidiary in 2007.

The plaintiff is seeking damages in excess of the Japanese Yen equivalent of $2,101. Several hearings have been held in the Tokyo District Court with respect to these claims. The Company’s Japanese subsidiary is vigorously contesting all of the claims asserted by the plaintiff.

The Company is also involved in various other legal matters incidental to its business. The Company believes, after consulting with counsel, that the disposition of these other legal matters will not have a material effect on our consolidated results of operations or consolidated financial position.

Indemnification

In the normal course of business the Company periodically enters into agreements to indemnify customers or suppliers against claims of intellectual property infringement made by third parties arising from the use of the Company’s products. Historically, costs related to these indemnification provisions have not been significant and we are unable to estimate the maximum potential impact of these indemnification provisions on our future results of operations.

To the extent permitted under Delaware law, the Company indemnifies directors and officers for certain events or occurrences while the director or officer is, or was serving, at the Company’s request in such capacity, subject to limited exceptions. The maximum potential amount of future payments we could be required to make under these indemnification obligations is unlimited; however, the Company has directors and officers insurance coverage that may enable the Company to recover future amounts paid, subject to a deductible and the policy limits. There is no assurance that the policy limits will be sufficient to cover all damages, if any.

Results of Operations

Summary of 2012 first quarter financial results

Our operating activities generated $15.8 million of cash during the first quarter of 2012, which is discussed in further detail below. We used $135.9 million to fund our strategic investing activities, including acquisition of businesses. Financing activities during the first quarter of 2012 provided $0.7 million of cash. In total, our unrestricted cash balance at March 31, 2012 was $60.0 million compared to $179.1 million at December 31, 2011. The December 31, 2011 balance included $145.4 million of net proceeds from the issuance of senior convertible notes in November 2011, of which $141.3 million was used to complete the acquisition of Z Corp and Vidar on January 3, 2012 and the related financing transaction.

17

During the first quarter of 2012 we reported improved revenue as compared to the first quarter of 2011 as our worldwide businesses continued to expand. Revenue for the first quarter of 2012 increased by 62.7% over the first quarter of 2011. This increase in revenue was led by a $11.2 million, or 82.6%, increase in sales of printers and other products together with a $9.1 million, or 58.1%, increase in print material sales and a $9.8 million, or 52%, increase in services revenue year-over-year. Higher revenue combined with increased selling, general and administrative expenses primarily related to acquisition expenses and interest expense on the convertible notes resulted in net income of $6.2 million for the first quarter of 2012, compared to net income of $6.8 million for the same period in 2011. Revenue for Z Corp and Vidar for the first quarter of 2012 was $12.4 million and the operating loss was $0.2 million, after taking into account the integration and severance costs.

Materials sales for the first quarter of 2012 rose by $9.1 million from the first quarter of 2011 as revenue from materials was favorably impacted by continued expansion of printers installed over past periods. In addition, production printer sales are typically accompanied by significant initial print materials purchases to charge up new systems and commence production.

Revenue from services increased by $9.7 million to $28.5 million in the first quarter of 2012 from $18.8 million in the same quarter in 2011. The increase in services revenue reflects revenue from our custom parts services and increased revenue from printer service components, from both organic growth and acquisitions. Service revenue from custom parts services was $17.7 million, or 62.0%, of total service revenue for the first quarter of 2012.

For the first quarter of 2012, healthcare solutions revenue made up 15%, or $12.0 million, of our total revenue compared to 13%, or $6.2 million, in the first quarter of 2011, primarily due to our increased penetration into healthcare applications and to our acquisition of Vidar . Healthcare solutions revenue includes sales of printers, print materials, and services for hearing aid, dental, medical device and other health-related applications. Although printer sales into these marketplaces can fluctuate from period to period due to timing, 54% of revenue from healthcare solutions was from recurring revenue in the first quarter of 2012 compared to 64% in the first quarter of 2011.

Our gross profit in the first quarter of 2012 improved primarily from our higher level of revenue from increases across all revenue categories, including increased revenue from our higher gross profit margin print materials, coupled with continued cost containment. Our gross profit margin increased to 49.9% in the first quarter of 2012 from 48.4% in the first quarter of 2011 due to product mix, with an increased portion of sales of higher margin print materials and improvements in our cost structure, notwithstanding the increased unit sales of lower margin printers.

Our total operating expenses increased by $13.1 million in the first quarter of 2012 to $28.9 million from $15.8 million in the 2011 quarter. The increase reflected higher selling, general and administrative expenses primarily due to higher commissions and staffing from our acquisitions, and acquisition integration and severance costs of $2.4 million during the first quarter of 2012 from which we expect annual savings of $5.0 million to $5.5 million. This is consistent with our previous expectations of achieving between $5.0 million and $10.0 million in synergies. The increase also reflected a $2.1 million increase in research and development expenses related to our new products and consumer solutions development and acquired R&D expenses. We expect to continue to manage expenses and drive down our costs where possible without impairing our ability to operate and service our customers.

Our operating income for the first quarter of 2012 increased to $10.0 million from $7.4 million in the 2011 quarter. This improvement in operating income improved from higher revenues and increased gross profit, partially offset by higher operating expenses, including acquisition expenses incurred, as discussed below.

First quarter comparison of revenue by class of product and service

We earn revenues from the sale of printers and other products, print materials and services. On a consolidated basis, revenue for the first quarter of 2012 increased by $30.0 million, or 62.7%, compared to the first quarter of 2011 primarily due to increased sales of printers and other products from acquired and organic growth, coupled with increased print materials and on-demand parts service revenue from acquired and organic growth.

The increase in revenue from printers and other products compared to the first quarter of 2011 is primarily due to increased printer unit sales volume for the first quarter of 2012 driven by increased demand for personal and professional printers and acquired printers revenue from the Z Corp and Vidar acquisitions that we completed in the first quarter of 2012.

Production printers made up $7.4 million, or 30.4%, of total printers revenue for the first quarter of 2012, compared to $8.4 million, or 62% for the first quarter of 2011. The decrease in production printers revenue is consistent with our ongoing plan to accelerate production printer adoption by introducing lower priced production printers, which are capable of using the same amount of materials as our higher priced production printers.

Due to the relatively high price of certain production printers and a corresponding lengthy selling cycle and relatively low unit volume of these higher priced production printer sales in any particular period, a shift in the timing and concentration of orders and shipments of a few printers from one period to another can significantly affect reported revenue in any given period. Revenue reported for printer sales in any particular period is also affected by revenue recognition rules prescribed by generally accepted accounting principles.

Personal and professional printers made up $16.9 million, or 69.6%, of total printers revenue for the first quarter of 2012, compared to $5.1 million, or 38%, for the first quarter of 2011. This represented a 230.0% increase in personal and professional printers revenue over the 2011 quarter.

The increase in revenue from print materials was aided by the improvement in printers sales and by the continued expansion of printers installed over past periods and by increased materials sales from the acquisitions of RenShape^® and Z Corp print materials. Sales of integrated materials represented 63% of total materials revenue in the first quarter of 2012 compared to 50% in the first quarter of 2011.

The increase in services revenue primarily reflects revenue from our on-demand parts services from both organic growth and acquisitions. Service revenue from on-demand parts services was $17.7 million, or 62.0% of total service revenue for the first quarter of 2012 compared to $10.3 million, or 54.8% of total service revenue in the 2011 period.

For the first quarter of 2012, Z Corp and Vidar contributed $12.4 million of revenue. For the first quarter of 2011, Z Corp and Vidar had revenue of $14.1 million. This decrease in revenue was primarily attributed to the revenue contributions of the OEM ZBuilder^® printer in the 2011 period, which was discontinued for the 2012 period. If Z Corp and Vidar had been included in our revenue for 2011, our overall corporate growth rate would have been 25.7%.

Taking into account all acquired businesses that we have owned for less than one year, our organic growth rate for the first quarter of 2012 was 26.1%.

At March 31, 2012 our backlog was $9.6 million, compared to backlogs of $8.3 million at December 31, 2011 and $7.9 million at March 31, 2011. Production and delivery of our printers is generally not characterized by long lead times, backlog is more dependent on timing of customers requested delivery. In addition, custom parts services lead time and backlog depends on whether orders are for rapid prototyping or longer-range production runs. The backlog at March 31, 2012 includes $5.7 million of custom parts services orders, compared to $4.3 million at March 31, 2011.

In addition to changes in sales volumes, there are two other primary drivers of changes in revenues from one period to another: the combined effect of changes in product mix and average selling prices, sometimes referred to as price and mix effects, and the impact of fluctuations in foreign currencies.

As used in this Management’s Discussion and Analysis, the price and mix effects relate to changes in revenue that are not able to be specifically related to changes in unit volume. Among these changes are changes in the product mix of our materials and our systems as the trend toward smaller, lower-priced printers has continued and the influence of new printers and print materials on our operating results has grown.

Change in first quarter revenue by geographic region

Each geographic region contributed to our higher level of revenue in first quarter of 2012. Table 2 sets forth the change in revenue by geographic area for the first quarter of 2012 compared to the first quarter of 2011:

Table 2

Revenue from U.S. operations increased by $23.0 million, or 100.7%, to $45.9 million in 2012 from $22.9 million in the first quarter of 2011. The increase was due to higher volume, partially offset by the unfavorable combined effect of price and mix.

Revenue from non-U.S. operations at March 31, 2012 increased by $7.0 million, or 27.9%, to $32.0 million from $25.0 million at March 31, 2011. Revenue from non-U.S. operations as a percent of total revenue was 41.1% and 52.2%, respectively, at March 31, 2012 and 2011. The increase in non-U.S. revenue, excluding the effect of foreign currency translation, was 30.5% in the first quarter of 2012 compared to 40.5% in the first quarter of 2011.

Revenue from European operations increased by $2.6 million, or 14.3%, to $20.7 million from $18.1 million in the prior year period. This increase was due to a $5.7 million increase in volume, partially offset by $2.3 million unfavorable combined effect of price and mix and a $0.8 million unfavorable impact of foreign currency translation.

Revenue from Asia-Pacific operations increased by $4.4 million, or 63.6%, to $11.3 million from $6.9 million in the prior year period due primarily to the favorable $5.9 million increase in volume combined with a $0.2 favorable impact of foreign currency translation, partially offset by an unfavorable $1.7 million combined effect of price and mix.

Gross profit and gross profit margins

Table 3 sets forth gross profit and gross profit margin for our products and services for the first quarters of 2012 and 2011:

Table 3

	Three Months Ended March 31,
	2012					2011
(Dollars in thousands)	Gross Profit		Gross Profit Margin			Gross Profit		Gross Profit Margin
Printers and other products	$	9,575		38.7	%	$	5,493		40.6	%
Print materials		16,775		68.0			9,900		63.4
Services		12,503		43.8			7,804		41.6
Total	$	38,853		49.9	%	$	23,197		48.4	%

On a consolidated basis, gross profit for the first quarter of 2012 increased by $15.7 million to $38.9 million from $23.2 million in the first quarter of 2011, primarily as a result of higher sales from all revenue categories and helped by an increase in our gross profit margin.

Consolidated gross profit margin in the first quarter of 2012 increased by 1.5 percentage points to 49.9% of revenue from 48.4% of revenue for the 2011 quarter. The higher gross profit margin reflected improvements in print materials and on-demand parts gross profit margins, partially offset by a higher portion of sales of lower gross profit margin personal and professional printers and a reduction of recognized deferred revenue due to the initial accounting for Z Corp and Vidar sales.

Printers and other products gross profit for the first quarter of 2012 increased to $9.6 million from $5.5 million for the 2011 quarter, and gross profit margin for printers decreased by 1.9 percentage points to 38.7% from 40.6% in the 2011 quarter primarily due to increased sales of lower margin personal and professional printers.

20

Print materials gross profit for the first quarter of 2012 increased by $6.9 million, or 69.4%, to $16.8 million from $9.9 million for the 2011 quarter, and gross profit margin for print materials increased by 4.6 percentage points to 68.0% from 63.4% in the 2011 quarter primarily due to the favorable shift of the mix of materials towards personal and professional print materials and integrated materials.

Gross profit for services for the first quarter of 2012 increased by $4.7 million, or 60.2%, to $12.5 million from $7.8 million for the 2011 quarter, and gross profit margin for services increased by 2.2 percentage points to 43.8% from 41.6% in the 2011 quarter. The increase in gross profit was due primarily to higher levels of revenue associated with our custom parts services. The increase in gross profit margin for services is primarily due to increased synergies from the integration of acquired custom parts services coupled with improved gross profit margin on printer services. On-demand custom parts services gross profit margin improved 1.7 percentage points to 40.9% for the first quarter of 2012 from 39.2% in the first quarter of 2011. Printer services has a gross profit margin of 47.9% compared to 44.5% for the first quarter of 2011.

Operating expenses

As shown in Table 4, total operating expenses increased by $13.1 million, or 83.0%, to $28.9 million in the first quarter of 2012 from $15.8 million in the first quarter of 2011. This increase was due to higher selling, general and administrative expenses and higher research and development expenses, both of which are discussed below.

Table 4

	Three Months Ended March 31,
	2012					2011
(Dollars in thousands)	Amount		% Revenue			Amount		% Revenue
Selling, general and administrative expenses	$	23,950		30.8	%	$	12,964		27.1	%
Research and development expenses		4,933		6.3			2,822		5.9
Total operating expenses	$	28,883		37.1	%	$	15,786		33.0	%

Selling, general and administrative expenses increased by $11.0 million to $24.0 million in the first quarter of 2012 compared to $13.0 million in the first quarter of 2011, and increased to 30.8% of revenue in 2012 compared to 27.1% for 2011. The increase was due primarily to a $7.3 million increase in compensation costs due to commissions on higher revenues and higher staffing from acquisitions and bonuses associated with the 2012 acquisition and integration activities. SG&A expenses included $2.4 million of acquisition and severance expenses, from which we expect to realize annual savings of $5.0 million to $5.5 million. Additionally, SG&A expenses were impacted by a $2.6 million increase in amortization expense due to acquired intangibles, a $1.4 million increase in marketing expenses and a $0.7 million increase in occupancy costs related to additional acquired locations and a $0.3 million increase in travel expenses, partially offset by a $0.3 million improvement in legal expenses.

Research and development expenses increased by $2.1 million, or 74.8%, to $4.9 million in the first quarter of 2012 from $2.8 million in the first quarter of 2011, principally due to a $1.2 million increase in compensation expense and a $0.4 million increase in operating supplies and R&D materials and a $0.3 million increase in outside vendors and contract labor in the 2012 quarter related to new products and consumer solutions development.

Income from operations

Our income from operations of $10.0 million for the first quarter of 2012 improved from $7.4 million in 2011. See Gross profit and gross profit margins and Operating expenses above.

The following table sets forth operating income by geographic area for the first quarter of 2012 compared to 2011:

21

With respect to the U.S., in 2012 and 2011, the changes in operating income by geographic area reflected the same factors discussed above in Gross profit and gross profit margins and Operating expenses.

As most of our operations outside the U.S. are conducted through sales and marketing subsidiaries, the changes in operating income in our operations outside the U.S. in 2012 and 2011 resulted primarily from changes in transfer pricing which is a function of revenue levels.

Interest and other expense (income), net

Interest and other expense (income), net was $2.7 million of expense, net in the first quarter of 2012 compared with $0.3 million of income, net in the 2011 quarter. The higher interest and other expense primarily reflected the interest related to the senior convertible notes issued in 2011, which amounted to $3.2 million of interest expense, of which $1.0 million represents non-cash amortization. Interest and other expense (income), net in the first quarter of 2012 also reflected foreign exchange gain of $0.5 million. The $0.3 million of interest and other income, net in the first quarter of 2011 reflected foreign exchange gain of $0.6 million, partially offset by $0.2 million of interest expense and $0.1 million of other expense.

Provision for income taxes

We recorded a $1.1 million provision for income taxes in the first quarter of 2012 and $0.9 million in 2011. Our 2012 provision for income taxes reflects primarily deferred U.S. income taxes associated with the use of net operating loss carryforwards. We released a portion of the valuation allowance related to our U.S. net deferred tax assets during 2011. The 2011 provision for income taxes primarily reflects tax expense associated with income taxes in non-U.S. jurisdictions.

We utilized U.S. net deferred tax assets, specifically net operating loss carryforwards and U.S. federal tax credits, in determining the effective tax rate for the year. This resulted in a reduction our effective tax rate. Absent the use of these net operating loss carryforwards and tax credits, income tax expense would have been $1.9 million and the income tax rate would have been 37.2 percent. Due to our U.S. net operating loss carryforwards, our rate of cash taxes was 10.4 percent of taxable income.

Our U.S. deferred income tax assets, against which there is a valuation allowance, have been partially utilized in determining the effective tax rate for 2012, with the remainder offset by the recognition of $17,071 of deferred income tax liabilities from the acquisitions of Z Corp and Vidar. We will continue our ongoing review of actual results and anticipated future earnings, and their impact on future releases of valuation allowances. As of March 31, 2012, the Company has a valuation allowance remaining on its U.S. net deferred tax assets of $8,549.

Net income

Our net income for the first quarter of 2012 decreased $0.6 million to $6.2 million compared to $6.8 million in the first quarter of 2011. The principal reasons for the decrease, which are discussed in more detail above, were:

• the $3.0 million increase in interest and other expense (income), net, and

• the $0.2 million increase in our tax provision; and

• partially offset by the $2.6 million increase in operating income as discussed above.

For the three months ended March 31, 2012, average common shares for basic and diluted earnings per share were 50.9 million and 51.7 million, respectively, and basic and diluted earnings per share were $0.12. For the three months ended March 31, 2011, average common shares for basic and diluted earnings per shares were 47.6 million and 48.6 million, respectively, and basic and diluted earnings per share were $0.14.

Other Financial Information

In addition to our results determined under U.S. generally accepted accounting principles (“GAAP”) discussed above, management believes non-GAAP financial measures, which adjust net income and earnings per share are useful to investors in evaluating our operating performance.

We use non-GAAP financial measures of adjusted net income and adjusted earnings per share to supplement our unaudited condensed consolidated financial statements presented on a GAAP basis to facilitate a better understanding of the impact that several strategic acquisitions had on our financial results.

These non-GAAP financial measures have not been prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies and they are subject to inherent limitations as they reflect the exercise of judgments by our management about which costs, expenses and other items are excluded from our GAAP financial statements in determining our non-GAAP financial measures. We have sought to compensate for these limitations by analyzing current and expected future results on a GAAP basis as well as a non-GAAP basis and also by providing GAAP financial statements as required in our public disclosures as well as reconciliations of our non-GAAP financial measures of adjusted net income and adjusted earnings per share to our GAAP financial statements.

22

The presentation of our non-GAAP financial measures which adjust net income and earnings per share are not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP. These non-GAAP financial measures are meant to supplement, and be viewed in conjunction with, GAAP financial measures. We urge investors to review the reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures included below, and not to rely on any single financial measure to evaluate our business.

Our non-GAAP financial measures which adjust net income and earnings per share are adjusted for the following:

Stock-based compensation expenses. We exclude the tax-effected stock-based compensation expenses from non-GAAP measures primarily because they are non-cash.

Amortization of intangibles. We exclude the tax-effected amortization of intangible assets. The increase in recent periods is primarily in connection with acquisitions of businesses.

Acquisition and severance expenses. We exclude the tax-effected charges associated with the acquisition of businesses and the related severance expenses.

Non-cash interest expenses. We exclude tax-effected, non-cash interest expenses, primarily related to the amortization costs associated with our outstanding senior convertible notes.

Release of valuation allowance on deferred tax assets. We exclude the tax-effected, non-cash benefit of the releases of portions of the valuation allowance on deferred tax assets.

Financial Condition and Liquidity

Table 6

(Dollars in thousands)	March 31, 2012		December 31, 2011
Cash and cash equivalents	$	60,027	$	179,120
Working capital		88,964		202,357
Total stockholders’ equity		264,117		254,788

Our unrestricted cash and cash equivalents decreased by $119.1 million to $60.0 million at March 31, 2012 from $179.1 million at December 31, 2011. The balance at December 31, 2011 included $145.4 million of net proceeds from senior convertible notes, of which $141.3 million was used to complete the acquisition of Z Corp and Vidar on January 3, 2012 and the related financing transaction. Excluding the proceeds of the convertible notes, cash increased $26.3 million. We generated $15.8 million of cash from operating activities, consisting of $8.5 million of non-cash charges that were included in our net income, our $6.2 million net income and $1.1 million of cash provided by net changes in operating accounts. We used $135.9 million of cash in investing activities. See Cash flow and Capitalized lease obligations below.

23

Cash equivalents comprise funds held in money market instruments and are reported at their current carrying value, which approximates fair value due to the short-term nature of these instruments. We minimize our credit risk by investing primarily in investment grade, liquid instruments and limit exposure to any one issuer depending on credit quality.

Our net working capital decreased by $113.4 million to $89.0 million at March 31, 2012 from $202.4 million at December 31, 2011, primarily due to the factors discussed below:

Our unrestricted cash and cash equivalents decreased by $119.1 million to $60.0 million at March 31, 2012 from $179.1 million at December 31, 2011. This decrease primarily was due to the balance at December 31, 2011 including $145.4 million of net proceeds from senior convertible notes, of which $134.9 million was used to complete the acquisition of Z Corp and Vidar on January 3, 2012. This decrease was partially offset by cash from operations of $15.8 million and $0.7 million from financing activities in the first quarter of 2012.

Accounts receivable, net, increased by $9.9 million to $61.1 million at March 31, 2012 from $51.2 million at December 31, 2011. Our gross accounts receivable increased by $10.4 million from December 31, 2011, primarily due to acquiring the receivables of Z Corp and Vidar and our changing business model, which includes custom parts services and increasing materials, both of which are generally sold on credit terms, make up a larger percent of our total sales. With an increased portion of our sales on credit terms, our days sales outstanding increased to 71 days at March 31, 2012 from 67 days at December 31, 2011 and accounts receivable more than 90 days past due decreased to 11.7% of gross receivables from 11.9% at December 31, 2011.

Inventories increased by $9.6 million to $34.9 million at March 31, 2012 from $25.3 million at December 31, 2011. This increase resulted primarily from a $9.1 million increase in finished goods inventory due the increased inventory related to the acquisition of Z Corp and Vidar and due to the timing of sales and revenue recognition at quarter-end, which also impacts our backlog, and a $1.2 million increase in raw materials primarily related to the timing of deliveries of raw materials and printer assembly parts. We maintained $3.4 million of inventory reserves at March 31, 2012 and $2.5 million of such reserves at December 31, 2011.

The majority of our inventory consists of finished goods, including primarily printers, print materials and service parts. Inventory also consists of raw materials and spare parts for the in-house assembly and support service for personal and professional 3D printers. We outsource the assembly and refurbishment of production printers; therefore, we generally do not hold in inventory most parts for production printer assembly or refurbishment.

Accounts payable increased by $7.2 million to $33.1 million at March 31, 2012 from $25.9 million at December 31, 2011. The increase primarily related to the normal timing of our scheduled expense payments, an increase in payables related to our acquisition of Z Corp and Vidar, and the increase in inventories, which is explained above.

Accrued and other liabilities increased by $6.4 million to $23.2 million at March 31, 2012 from $16.8 million at December 31, 2011. This increase is primarily due to an increase in accrued compensation related to higher compensation costs and bonuses related to the acquisition and integration of Z Corp and Vidar and an increase in accrued interest related to the senior convertible notes.

The changes in the first quarter of 2012 that make up the other components of working capital not discussed above arose in the ordinary course of business.

Differences between the amounts of working capital item changes in the cash flow statement and the balance sheet changes for the corresponding items are primarily the result of foreign currency translation adjustments.

We have relied on our unrestricted cash, cash flow from operations and capital markets transactions to meet our cash requirements for working capital, capital expenditures and acquisitions. However, it is possible that we may need to raise additional funds to finance our activities beyond the next twelve months or to consummate significant acquisitions of other businesses, assets, products or technologies. If needed, we may be able to raise such funds by issuing equity or debt securities to the public or selected investors, or by borrowing from financial institutions, selling assets or restructuring debt.

Cash flow

Table 7 summarizes the cash provided by or used in operating activities, investing activities and financing activities, as well as the effect of changes in foreign currency exchange rates on cash, for the first three months of 2012 and 2011.

Table 7

(Dollars in thousands)	2012			2011
Cash provided by operating activities	$	15,827		$	289
Cash used in investing activities		(135,904	)		(22,666	)
Cash provided by financing activities		746			55,461
Effect of exchange rate changes on cash		238			395
Net increase (decrease) in cash and cash equivalents	$	(119,093	)	$	33,479

Cash flow from operating activities

For the three months ended March 31, 2012, our operating activities provided $15.8 million of net cash. This source of cash consisted primarily of net income plus the effects of non-cash items and changes in working capital, which are described above.

For the three months ended March 31, 2011, our operating activities provided $0.3 million of net cash. This source of cash consisted of our $6.8 million net income, $3.6 million of non-cash items included in our net income and $10.1 million of cash used by net changes in operating accounts.

Cash flow from investing activities

Net cash used in investing activities in the first three months of 2012 increased to $135.9 million from $22.7 million for the first three months of 2011. This increase was primarily due to $134.9 million of cash paid for acquisitions in the first quarter of 2012 compared to $22.1 million paid for acquisitions in the 2011 period.

Cash flow from financing activities

Net cash provided by financing activities decreased to $0.7 million for the three months ended March 31, 2012 compared to $55.5 million in the 2011 period. Cash from financing activities in the first quarter of 2012 was from $0.8 million of stock-based compensation proceeds, partially offset by capital lease payments. Cash from financing activities in the three months ended March 31, 2011 included $54.0 million of net proceeds resulting from our Common Stock offering in March 2011 coupled with $1.5 million of stock-based compensation proceeds.

Contractual commitments and off-balance sheet arrangements

Debt

As discussed above, in November 2011, we issued senior convertible notes due 2016 in an aggregate principal amount of $152.0 million. These notes bear interest at a fixed rate of 5.50% per annum, payable June 15 and December 15 of each year while they are outstanding, beginning June 15, 2012. The net proceeds of the notes were used to fund the acquisition of Z Corp and Vidar and for general corporate purposes. See Notes 2 and 8 to the unaudited condensed consolidated financial statements.

The Notes have an initial conversion rate of 46.6021 shares of Common Stock per $1,000 principal amount of Notes, which amounts to a conversion price of $21.46 per common share. Upon conversion, the Company has the option to pay cash or issue Common Stock, or a combination thereof. The Notes are convertible at the option of the holders at any time. The aggregate principal amount of these Notes then outstanding matures on December 15, 2016, unless earlier converted, redeemed or repurchased in accordance with the terms of the Notes.

The Notes contain a number of covenants covering, among other things, payment of notes, reporting, maintenance of existence and payment of taxes. Failure to comply with these covenants, or any other event of default, could result in acceleration of the principal amount and accrued and unpaid interest on the notes. We were in compliance with all covenants as of March 31, 2012. See Note 8 to the unaudited condensed consolidated financial statements.

Capitalized lease obligations

Our principal contractual commitments consist of capitalized lease obligations of $7.7 million at March 31, 2012. Our capitalized lease obligations, which primarily relate to a lease agreement that we entered into during 2006 with respect to our Rock Hill facility which covers the facility itself, decreased to $7.7 million at March 31, 2012 from $7.8 million at December 31, 2011 primarily due to scheduled payments of principal on capital lease installments.

25

Our outstanding capitalized lease obligations carrying values at March 31, 2012 and December 31, 2011 were as follows:

Table 8

(Dollars in thousands)	March 31, 2012		December 31, 2011
Capitalized lease obligations:
Current portion of capitalized lease obligations	$	160	$	163
Capitalized lease obligations, long-term portion		7,574		7,609
Total capitalized lease obligations	$	7,734	$	7,772

Other contractual commitments

For certain of our recent acquisitions we are obligated for the payment of deferred purchase price totaling $1.1 million, due in 2012 and 2013, compared to $1.4 million at December 31, 2011. Certain of our recent acquisitions contain earnout provisions under which the sellers of the acquired businesses can earn additional amounts. The total amount of liabilities recorded for these earnouts at March 31, 2012 is $1.9 million, compared to $1.9 million at December 31, 2011. See Note 2 for details of acquisitions and related commitments.

As of March 31, 2012, we have supply commitments related to printer assembly that total $7.6 million compared to $10.9 million at December 31, 2011.

Off-balance sheet arrangements

We have no off-balance sheet arrangements and do not utilize any “structured debt,” “special purpose,” or similar unconsolidated entities for liquidity or financing purposes.

Financial instruments

We conduct business in various countries using both the functional currencies of those countries and other currencies to effect cross border transactions. As a result, we are subject to the risk that fluctuations in foreign exchange rates between the dates that those transactions are entered into and their respective settlement dates will result in a foreign exchange gain or loss. When practicable, we endeavor to match assets and liabilities in the same currency on our balance sheet and those of our subsidiaries in order to reduce these risks. We also, when we consider it to be appropriate, enter into foreign currency contracts to hedge exposures arising from those transactions.

We do not hedge or trade for speculative purposes, and our foreign currency contracts are generally short-term in nature, typically maturing in 90 days or less. We have elected not to prepare and maintain the documentation to qualify for hedge accounting treatment under ASC 815, “Derivatives and Hedging,” and therefore, we recognize all gains and losses (realized or unrealized) in interest and other expense (income), net in our unaudited condensed consolidated statements of operations and comprehensive income.

There were no foreign exchange contracts at March 31, 2012 or December 31, 2011. See Note 7 of the unaudited condensed consolidated financial statements.

Changes in the fair value of derivatives are recorded in interest and other expense (income), net, in our unaudited condensed consolidated statements of operations and comprehensive income. Depending on their fair value at the end of the reporting period, derivatives are recorded either in prepaid and other current assets or in accrued liabilities in our unaudited condensed consolidated balance sheets.

The total impact of foreign currency related items on our unaudited condensed consolidated statements of operations and comprehensive income was a $0.5 million gain for the three months ended March 31, 2012 and a $0.6 million gain for the three months ended March 31, 2011.

Recent Accounting Pronouncements

Critical Accounting Policies and Significant Estimates

For a discussion of our critical accounting policies and estimates, refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Significant Estimates” in our Annual Report on Form 10-K for the year ended December 31, 2011.

Forward-Looking Statements

Certain statements made in this Form 10-Q that are not statements of historical or current facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include the cautionary statements and risk factors set forth below as well as other statements made in the Form 10-Q that may involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from historical results or from any future results expressed or implied by such forward-looking statements.

In addition to statements that explicitly describe such risks and uncertainties, readers are urged to consider statements in future or conditional tenses or that include terms such as “believes,” “belief,” “expects,” “intends,” “anticipates” or “plans” to be uncertain and forward-looking. Forward-looking statements may include comments as to our beliefs and expectations as to future events and trends affecting our business. Forward-looking statements are based upon management’s current expectations concerning future events and trends and are necessarily subject to uncertainties, many of which are outside of our control. The factors stated under the heading “Cautionary Statements and Risk Factors” set forth below and those described in our other SEC reports, including our Form 10-K for the year ended December 31, 2011, as well as other factors, could cause actual results to differ materially from those reflected or predicted in forward-looking statements.

Any forward-looking statements are based on management’s beliefs and assumptions, using information currently available to us. We assume no obligation, and do not intend, to update these forward-looking statements.

If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may vary materially from those reflected in or suggested by forward-looking statements. Any forward-looking statement you read in this Form 10-Q reflects our current views with respect to future events and is subject to these and other risks, uncertainties and assumptions relating to our operations, results of operations, growth strategy and liquidity. All subsequent written and oral forward-looking statements attributable to us or individuals acting on our behalf are expressly qualified in their entirety by this paragraph. You should specifically consider the factors identified or referred to in this Form 10-Q and our other SEC reports, including our Annual Report on Form 10-K for the year ended December 31, 2011, which would cause actual results to differ from those referred to in forward-looking statements.

Cautionary Statements and Risk Factors

We recognize that we are subject to a number of risks and uncertainties that may affect our future performance. The risks and uncertainties described in Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2011 are not the only risks and uncertainties that we face. Additional risks and uncertainties not currently known to us or that we currently deem not to be material also may impair our business operations. If any of these risks actually occur, our business, results of operations and financial condition could suffer. In that event the trading price of our common stock could decline, and you may lose all or part of your investment in our common stock. The risks discussed in Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2011 also include forward-looking statements, and our actual results may differ substantially from those discussed in these forward-looking statements.

Except as required by the federal securities laws, we undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

Item  3. Quantitative and Qualitative Disclosures About Market Risk.

For a discussion of market risks at December 31, 2011, refer to Item 7A, “Quantitative and Qualitative Disclosures about Market Risk,” in our Annual Report on Form 10-K for the year ended December 31, 2011. During the first three months of 2012, there were no material changes or developments that would materially alter the market risk assessment performed as of December 31, 2011.

Item 4. Controls and Procedures.

Evaluation of disclosure controls and procedures

As of March 31, 2012, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) pursuant to Rules 13a-15 and 15d-15 under the Exchange Act. These controls and procedures were designed to provide reasonable assurance that the information required to be disclosed 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 our Chief Executive Officer and Chief Financial Officer, in a manner to allow timely decisions regarding required disclosures. Based on this evaluation, including an evaluation of the rules referred to above in this Item 4, management has concluded that our disclosure controls and procedures were effective as of March 31, 2012 to provide reasonable assurance that the information required to be disclosed in the reports 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 management, including our Chief Executive Officer and Chief Financial Officer, in a manner to allow timely decisions regarding required disclosures.

Changes in Internal Controls over Financial Reporting
