Discussion of Adjusted Financial Measures

In addition to our GAAP results, we provide adjusted revenues, adjusted EBITDA, adjusted EBITDA excluding stock-based compensation, adjusted net income, adjusted net income excluding intangible asset amortization, adjusted earnings per diluted share and adjusted earnings per diluted share excluding intangible asset amortization. Adjusted revenues consist of growth in total revenues excluding the effects of currency exchange rates. The various measures of adjusted EBITDA consist of GAAP net income (loss), excluding: (i) income taxes,
(ii) other income (expense), net, (iii) depreciation and amortization, (iv) interest income and expense, (v) those operating expenses also excluded from adjusted net income and, as appropriate (vi) stock-based compensation expense. The various measures of adjusted net income consist of GAAP net income (loss), excluding: (i) acquisition-related charges; (ii) facility consolidation, manufacturing and distribution transfer and system integration charges; (iii) certain employee termination and related costs; (iv) charges associated with discontinued or withdrawn product lines; (v) charges related to restructuring our European subsidiaries; (vi) charges or gains related to litigation matters or disputes; (vii) intangible asset impairment charges; (viii) incremental professional and bank fees related to (a) the delayed filing of financial statements and (b) waivers or possibility of obtaining waivers under our revolving credit facility; (ix) charges recorded in connection with terminating defined benefit pension plans; (x) charges relating to the grant of restricted stock units in connection with the extension of the term of the CEO's employment agreement; (xi) loss/gain related to the early extinguishment of convertible notes; (xii) non-cash interest expense related to the application of FSP APB 14-1; (xiii) the income tax expense/benefit related to these adjustments; (xiv) quarterly adjustments to income tax expense/benefit related to the cumulative impact of changes in estimated tax rates and certain infrequently occurring items; (xv) income tax expenses or gains related to restructuring our European subsidiaries; and, as appropriate, (xvi) intangible asset amortization expense. Adjusted net income attributable to diluted shares is calculated by multiplying adjusted net income by the diluted share percentage. The various adjusted earnings per diluted share measures are calculated by dividing the applicable adjusted net income attributable to diluted shares by diluted weighted average shares outstanding. Reconciliations of GAAP revenues to adjusted revenues for the quarter ended September 30, 2009, and GAAP net income (loss) to adjusted EBITDA, adjusted EBITDA excluding stock-based compensation, adjusted net income and adjusted net income excluding intangible asset amortization, and GAAP earnings (loss) per diluted share to adjusted earnings per diluted share and adjusted earnings per diluted share excluding intangible asset amortization for the quarters ended September 30, 2009 and 2008 appear in the financial tables in this release.

The Company believes that the presentation of adjusted revenues and the various adjusted EBITDA, adjusted net income and adjusted earnings per diluted share measures provides important supplemental information to management and investors regarding financial and business trends relating to the Company's financial condition and results of operations. Management uses non-GAAP financial measures in the form of adjusted revenues, adjusted EBITDA, adjusted EBITDA excluding stock-based compensation, adjusted net income, adjusted net income excluding intangible asset amortization, adjusted earnings per diluted share and adjusted earnings per diluted share excluding intangible asset amortization when evaluating operating performance because we believe that the inclusion or exclusion of the items described below, for which the amounts and/or timing may vary significantly depending upon the Company's acquisition, integration, and restructuring activities, for which the amounts are non-cash in nature, or for which the amounts are not expected to recur at the same magnitude as we implement certain tax planning strategies, provides a supplemental measure of our operating results that facilitates comparability of our operating performance from period to period, against our business model objectives, and against other companies in our industry. We have chosen to provide this information to investors so they can analyze our operating results in the same way that management does and use this information in their assessment of our core business and the valuation of our Company.

Adjusted revenues, adjusted EBITDA, adjusted EBITDA excluding stock-based compensation, adjusted net income, adjusted net income excluding intangible asset amortization, adjusted earnings per diluted share and adjusted earnings per diluted share excluding intangible asset amortization are significant measures used by management for purposes of:

• supplementing the financial results and forecasts reported to the Company's board of directors;

• evaluating, managing and benchmarking the operating performance of the Company;

• establishing internal operating budgets;

• determining compensation under bonus or other incentive programs;

• enhancing comparability from period to period;

• comparing performance with internal forecasts and targeted business models; and

• evaluating and valuing potential acquisition candidates.

The measure of adjusted revenues that we report reflects the growth in total revenues for the quarter ended September 30, 2009 adjusted for the effects of currency exchange rates on current period revenues. We provide this measure because changes in foreign currency exchange rates can distort our revenue growth favorably or unfavorably, depending upon the strength of the U.S. dollar in relation to the various foreign currencies in which we generate revenues. We generate significant revenues outside the United States in multiple foreign currencies including euros, British pounds, Swiss francs and Canadian dollars. We believe this measure provides useful information to determine the success of our international selling organizations in increasing sales of products in their local currencies without regard to fluctuations in currency exchanges rates, for which we have no control over.

The various measures of adjusted net income reflect GAAP net income (loss) adjusted for one or more of the following items, as applicable:

• Acquisition-related charges. Acquisition-related charges include in-process research and development charges, inventory fair value purchase accounting adjustments, impairments to existing intangible assets in connection with a subsequent acquisition, and legal, accounting and other outside consultants expenses directly related to acquisitions. Inventory fair value purchase accounting adjustments consist of the increase to cost of goods sold that occur as a result of expensing the "step up" in the fair value of inventory that we purchased in connection with acquisitions as that inventory is sold during the financial period. Although recurring given the ongoing character of our acquisition program, these acquisition-related charges are not factored into the evaluation of our performance by management after completion of acquisitions because they are of a temporary nature, they are not related to our core operating performance and the frequency and amount of such charges vary significantly based on the timing and magnitude of our acquisition transactions as well as the level of inventory on hand at the time of acquisition.

• Facility consolidation, manufacturing and distribution transfer and system integration charges. These charges, which include employee termination and other costs associated with exit or disposal activities, costs related to transferring manufacturing and/or distribution activities to different locations, and costs associated with the worldwide implementation of a single enterprise resource planning system, result from rationalizing and enhancing our existing manufacturing, distribution and administrative infrastructure. Many of these cost-saving and efficiency-driven activities are identified as opportunities in connection with acquisitions that provide the Company with additional capacity or economies of scale. Although recurring in nature given management's ongoing review of the efficiency of our manufacturing, distribution and administrative facilities and operations, management excludes these items when evaluating the operating performance of the Company because the frequency and amount of such charges vary significantly based on the timing and magnitude of the Company's rationalization activities and are, in some cases, dependent upon opportunities identified in acquisitions, which also vary in frequency and magnitude.

• Employee termination and related costs. Employee termination and related costs consist of charges related to significant reductions in force that are not initiated in connection with facility consolidations or manufacturing transfers and senior management level terminations. Management excludes these items when evaluating the Company's operating performance because these amounts do not affect our core operations and because of the infrequent and/or large-scale nature of these activities.

• Charges associated with discontinued or withdrawn product lines. This represents charges taken and reductions in revenue recorded in connection with product lines that the Company discontinues or withdraws. Management excludes this item when evaluating the Company's operating performance because of the infrequent nature of this activity or because many such product discontinuations are related to recent acquisitions.

• Charges related to restructuring our European subsidiaries. These amounts represent charges recorded in operating or non-operating expenses such as levies and fees paid to government authorities, legal, tax, accounting and consulting fees, and foreign currency gains and losses related to intercompany loan agreements incurred directly as a result of reorganizing our European subsidiaries and transfers of business assets between these legal entities. Management excludes this item when evaluating the Company's operating performance because of the infrequent nature of this activity.

• Charges or gains related to litigation matters or disputes. These charges or gains include estimated losses, gains or actual settlements and judgments against or in favor of the Company related to litigation, disputes or similar matters. Management excludes these items when evaluating Integra's operating performance because of the infrequent nature of these matters.

• Intangible asset impairment charges. This represents impairment charges recorded against various intangible assets, including completed or core technology, customer relationships, and tradenames. Such impairments result primarily from management decisions to discontinue or significantly reduce promoting certain product lines or tradenames, the inability to incorporate existing product technologies into product development programs, and other circumstances. Management excludes this item when evaluating the Company's operating performance because of the infrequent and non-cash nature of this activity.

• Incremental professional and bank fees related to (a) the delayed filing of financial statements and (b) waivers or the possibility of obtaining waivers under our revolving credit facility. These charges include audit fee overruns from our independent registered accounting firm, fees for legal advice and consultations with our external counsel and incremental efforts by consultants, and fees paid to various banks in connection with waivers or the possibility of obtaining waivers related to the late filing of our Annual Report on Form 10-K for the year ended December 31, 2007 and certain non-financial debt covenants. Management excludes these items when evaluating the Company's operating performance because such incremental amounts are not expected to be incurred again.

• Charges recorded in connection with terminating defined benefit pension plans. . . .
