The statements made in this presentation and in the oral remarks accompanying these slides that are not statements of current or historical fact are "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of Securities Exchange Act of 1934, as amended. We have based these forward-looking statements on our current expectations, and these statements are subject to known and unknown risks, uncertainties and assumptions. These forward-looking statements include statements relating to: future sales, expenses and profitability; future development and expected growth of our business, industries and markets; our ability to execute our business model and our business strategy; our ability to identify trends within our industries and markets and to offer products and services that meet the changing needs of those markets; and projected capital and other expenditures. You can identify forward-looking statements by terminology such as "may," "will," "should," "could," "expects," "intends," "plans," "anticipates," "believes," "estimates," "predicts," "potential" or "continue" or "variations" or the negative of these terms or other comparable terminology. These statements are only predictions. Actual events or results may differ materially from those stated or implied by these forward-looking statements. We are under no duty to update any of these forward-looking statements or to conform these statements to actual results. In evaluating these statements and our prospects, you should carefully consider the factors set forth below. Although it is not possible to create a comprehensive list of all factors that may cause actual results to differ from the results expressed or implied by the forward-looking statements contained in this presentation or that may affect our future results, some of these factors include the following: our dependence upon a limited number of customers; customer ordering patterns; product obsolescence; our inability to market current or future products; pricing pressure from customers; our ability to timely and successfully implement cost reduction and plant consolidation initiatives; our reliance on third party suppliers for raw materials, products and subcomponents; fluctuating operating results; our inability to maintain high quality standards for our products; challenges to our intellectual property rights; product liability claims; our inability to successfully consummate and integrate acquisitions and to realize synergies and to operate these acquired businesses in accordance with expectations; our unsuccessful expansion into new markets; our failure to develop new products including system and device products; our inability to obtain licenses to key technology; regulatory changes or consolidation in the healthcare industry; global economic factors including currency exchange rates and interest rates; the resolution of various legal actions brought against the Company; those risks set forth in our 2012 Form 10-K filed with the SEC on February 27, 2013; and other risks and uncertainties that arise from time to time. Forward Looking Statement 99

This presentation contains non-GAAP financial measures. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company's reported results prepared in accordance with GAAP. In this presentation: "adjusted" amounts consist of GAAP amounts (or forecasted GAAP amounts) excluding (i) acquisition-related charges, (ii) facility consolidation, optimization, manufacturing transfer and system integration charges, (iii) asset write-down and disposition charges, (iv) severance charges in connection with corporate realignments or a reduction in force (v) litigation charges and gains, (vi) the impact of non-cash charges to interest expense due to the accounting change governing convertible debt, (vii) unusual or infrequently occurring items, (viii) certain RD&E expenditures, such as design verification testing ("DVT") expenses incurred in connection with the development of our neuromodulation platform, (ix) gain/loss on the sale of investments, (x) the income tax (benefit) related to these adjustments and (xi) certain tax charges related to the consolidation of our Swiss Orthopaedic facility. We believe that reporting these amounts provides important supplemental information to our investors and creditors seeking to understand the financial and business trends relating to our financial condition and results of operations. Please see our 2012 Form 10-K filed with the SEC on February 27, 2013 for a reconciliation of the non-GAAP measures contained in this presentation. Non-GAAP Financial Measures 100
