Achievement of 2009 Earn-out

EBITDA Reconciliation

(Unaudited)

EBITDA (earnings before interest, taxes, depreciation and amortization) for the fourth quarter of 2009 rose to $9.4 million, an increase of 63.9% from the fourth quarter of 2008. EBITDA is not a measure of financial performance under generally accepted accounting principles (“GAAP”). Management believes EBITDA, in addition to operating profit, net income and other GAAP measures, is a useful indicator of Hill’s financial and operating performance and its ability to generate cash flows from operations that are available for taxes and capital expenditures. Investors should recognize that EBITDA might not be comparable to similarly-titled measures of other companies. This measure should be considered in addition to, and not as a substitute for or superior to, any measure of performance prepared in accordance with GAAP. A reconciliation of EBITDA to the most directly comparable GAAP measure in accordance with SEC Regulation S-K follows:
