Non-GAAP Financial Measures

Adjusted EBITDA discussed in this press release is defined as net income (loss) plus interest expense, other expense, income tax provision, depreciation and amortization, amortization of marketing agreement intangible assets, stock-based compensation

expense and, for 2011 only, restructuring charge and increase in fair value of warrants for redeemable convertible preferred stock; less amortization of leasehold interest and interest income.  Non-GAAP operating income excludes stock-based compensation expense, amortization of intangible assets, amortization of debt discount, and, for 2011 only, restructuring charge and amortization of deferred financing costs.  Non-GAAP net income excludes stock-based compensation expense, amortization of intangible assets, amortization of debt discount, and, for 2011 only, restructuring charge, term loan repayment fee, term loan debt discount, amortization of deferred financing costs and increase in fair value of warrants for redeemable convertible preferred stock.  Unlevered free cash flow is defined as net cash provided by operating activities plus net interest payments and, for 2011 only, IPO related expense payments, less capital expenditures. Management presents these non-GAAP financial measures because it considers them to be important supplemental measures of performance. Management uses the non-GAAP financial measures for planning purposes, including analysis of the company’s performance against prior periods, the preparation of operating budgets and determination of appropriate levels of operating and capital investments. Management also believes that the non-GAAP financial measures provide additional insight for analysts and investors in evaluating the company’s financial and operational performance. However, these non-GAAP financial measures have limitations as an analytical tool and are not intended to be an alternative to financial measures prepared in accordance with GAAP. We intend to provide these non-GAAP financial measures as part of our future earnings discussions and, therefore, the inclusion of these non-GAAP financial measures will provide consistency in our financial reporting. A reconciliation of these non-GAAP measures to GAAP is provided in the accompanying tables.
