Certain statements contained herein that are not descriptions of historical facts are “forward-looking” statements (as such term is defined in the Private Securities Litigation Reform Act of 1995).  Because such statements include risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements due to factors including the following:

·                     changes in government reimbursement for our services due to the implementation of healthcare reform legislation, deficit reduction measures, and/or new payment policies may result in a reduction in net operating revenues, an increase in costs and a reduction in profitability;

·                     the failure of our specialty hospitals to maintain their Medicare certifications may cause our net operating revenues and profitability to decline;

·                     the failure of our facilities operated as “hospitals within hospitals” to qualify as hospitals separate from their host hospitals may cause our net operating revenues and profitability to decline;

·                     a government investigation or assertion that we have violated applicable regulations may result in sanctions or reputational harm and increased costs;

·                     acquisitions or joint ventures may prove difficult or unsuccessful, use significant resources or expose us to unforeseen liabilities;

·                     private third-party payors for our services may undertake future cost containment initiatives that limit our future net operating revenues and profitability;

·                     the failure to maintain established relationships with the physicians in the areas we serve could reduce our net operating revenues and profitability;

·                     shortages in qualified nurses or therapists could increase our operating costs significantly;

·                     competition may limit our ability to grow and result in a decrease in our net operating revenues and profitability;

·                     the loss of key members of our management team could significantly disrupt our operations;

VIII. Net Income to Adjusted EBITDA Reconciliation

For the Three and Nine Months Ended September 30, 2012 and 2013

(In thousands, unaudited)

The following table reconciles net income to Adjusted EBITDA for Select Medical.  Adjusted EBITDA is used by Select Medical to report its segment performance.  Adjusted EBITDA is defined as net income before interest, income taxes, depreciation and amortization, gain (loss) on early retirement of debt, stock compensation expense, equity in earnings (losses) of unconsolidated subsidiaries and other income (expense).  The Company believes that the presentation of Adjusted EBITDA is important to investors because Adjusted EBITDA is commonly used as an analytical indicator of performance by investors within the healthcare industry.  Adjusted EBITDA is used by management to evaluate financial performance and determine resource allocation for each of its operating units.

Adjusted EBITDA is not a measure of financial performance under generally accepted accounting principles.  Items excluded from Adjusted EBITDA are significant components in understanding and assessing financial performance.  Adjusted EBITDA should not be considered in isolation or as an alternative to, or substitute for, net income, cash flows generated by operations, investing or financing activities, or other financial statement data presented in the consolidated financial statements as indicators of financial performance or liquidity.  Because Adjusted EBITDA is not a measurement determined in accordance with generally accepted accounting principles and is thus susceptible to varying calculations, Adjusted EBITDA as presented may not be comparable to other similarly titled measures of other companies.

(a)   Other primarily includes general and administrative costs.
