2 Forward Looking Statements and Non-GAAP Information This presentation contains “forward-looking statements”. Other than statements of historical facts, all statements contained in this presentation, including statements regarding the Company’s future financial position, future revenue, prospects, plans and objectives of management, are forward-looking statements. Words such as “outlook,” “believe,” “expect,” “anticipate,” “estimate,” “intend,” “should,” “could,” “project,” and similar expressions, as well as statements in future tense, identify forward-looking statements. You should not consider forward-looking statements as a guarantee of future performance or results. Forward-looking statements are based on information available at the time those statements are made and/or management’s good faith belief at that time with respect to future events. Such statements are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors, assumptions, uncertainties, and risks that could cause such differences are discussed in our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on September 4, 2015, our Quarterly Report on Form 10-Q filed with the SEC on May 27, 2016 and other filings with the SEC. The forward-looking statements in this presentation are expressly qualified in their entirety by this cautionary statement. The Company undertakes no obligation to update these forward-looking statements to reflect new information, or events or circumstances arising after such date. This presentation includes certain “Non-GAAP” financial measures as defined by Regulation G of the SEC. As required by the SEC, we have provided a reconciliation of those measures to the most directly comparable GAAP measures on the Regulation G slides included as slides 13 through 19 of this presentation. Non-GAAP financial measures should be considered in addition to, but not as a substitute for, our reported GAAP results.

19 Explanation of Non-GAAP Measures The Company reports its financial results in accordance with U.S. generally accepted accounting principles (GAAP). In the Company’s quarterly results releases, trend schedules, conference calls, slide presentations, and webcasts, it may use or discuss Non-GAAP financial measures, as defined by Regulation G of the Securities and Exchange Commission. The Company believes that the presentation of certain Non-GAAP financial measures in these materials provides information that is useful to investors because it allows for a more direct comparison of the Company’s performance for the period reported with the Company’s performance in prior periods. The Company cautions that Non-GAAP financial measures should be considered in addition to, but not as a substitute for, the Company’s reported GAAP results. Management defines the Non-GAAP financial measures as follows: • Non-GAAP Organic Contract Revenues - contract revenues from businesses that are included for the entire period in both the current and prior year periods and adjusted for the additional week in Q4-16 as a result of our 52/53 week fiscal year. Non-GAAP Organic Revenue growth (decline) is calculated as the percentage change in Non-GAAP Organic Contract Revenues over those of the comparable prior year period. Management believes organic growth (decline) is a helpful measure for comparing the Company’s revenue performance with prior periods. • Non-GAAP Adjusted EBITDA - net income before interest, taxes, depreciation and amortization, gain on sale of fixed assets, stock-based compensation expense, loss on debt extinguishment, and certain non-recurring items. Management believes Non-GAAP Adjusted EBITDA is a helpful measure for comparing the Company’s operating performance with prior periods as well as with the performance of other companies with different capital structures or tax rates. • Non-GAAP Adjusted Net Income - GAAP net income before loss on debt extinguishment, non-cash amortization of the debt discount, certain non-recurring items and any tax impact related to these items, and "Non-GAAP Adjusted Diluted Earnings per Common Share" as Non-GAAP Adjusted Net Income divided by weighted average diluted shares outstanding. Management excludes or adjusts each of the items identified below from Non-GAAP Adjusted Net Income and Non-GAAP Adjusted Diluted Earnings per Common Share: • Non-cash amortization of the debt discount - The Company’s 0.75% senior convertible notes due 2021 (the "Notes") were allocated between debt and equity components. The difference between the principal amount and the carrying amount of the liability component of the notes represents a debt discount. The debt discount will be amortized over the term of the notes but will not result in periodic cash interest payments. During the three months ended October 24, 2015, January 23, 2016, April 23, 2016, and July 30, 2016 the Company recognized approximately $1.8 million, $4.1 million, $4.2 million and $4.6 million, respectively, in pre-tax interest expense for non-cash amortization of the debt discount associated with the Notes. The Company has excluded the non-cash amortization of the debt discount from its Non-GAAP financial measures because it believes it is useful to analyze the component of interest expense for the Notes that will be paid in cash. The exclusion of the non-cash amortization from the Company’s Non-GAAP financial measures provides management with a consistent measure for assessing financial results. • Loss on debt extinguishment - The Company incurred a pre-tax charge of approximately $16.3 million for early extinguishment of debt in connection with the redemption of its 7.125% senior subordinated notes during the first quarter of fiscal 2016. Management believes excluding the loss on debt extinguishment from the Company’s Non-GAAP financial measures assists investors’ overall understanding of the Company's current financial performance. The Company believes this type of charge is not indicative of its core operating results. The exclusion of the loss on debt extinguishment from the Company’s Non-GAAP financial measures provides management with a consistent measure for assessing the current and historical financial results. • Acquisition transaction related costs – The Company incurred costs of approximately $0.7 million in connection with the acquisition of Goodman Networks during the fourth quarter of fiscal 2016. The exclusion of the acquisition transaction related costs from the Company’s Non-GAAP financial measures provides management with a consistent measure for assessing financial results. • Tax impact of adjusted results - The tax impact of the adjusted results was calculated utilizing a Non-GAAP effective tax rate which approximates the Company’s effective tax rate used for financial planning. The tax impact included in the Company’s guidance for the quarter ending July 30, 2016 was calculated using an effective tax rate used for financial planning and forecasting future results.
