(2) References to adjusted operating margin and adjusted EPS for 2012, 2013 and 2014 are non-GAAP measures. For a reconciliation to the appropriate GAAP measure, see the Appendix of this presentation. (3) The Company defines free cash flow as net cash provided by operating activities less capital expenditures. Cash Conversion is equal to Net Cash Provided by Operating Activities less Capital Expenditures divided by Net Income (2011 excludes the loss on sale of Barnes Distribution Europe; 2013 excludes the income taxes paid and gain on sale of the BDNA disposition, and the impact of the U.S. Tax Court's unfavorable decision rendered on April 16, 2013.) (4) All previously reported financial information, except for Free Cash Flow, has been adjusted on a retrospective basis to reflect discontinued operations. -15-

Diluted Income from Continuing Operations per Share as adjusted (Non-GAAP) (2)

(2) The Company has excluded the following from its "as adjusted" financial measurements: 1) short-term purchase accounting adjustments and transaction costs related to its Synventive acquisition in 2012, 2) CEO transition costs associated with the modification of outstanding equity awards in 2013, 3) the tax charge associated with the April 2013 tax court decision in 2013 and 4) short-term purchase accounting adjustments and transaction costs related to its Männer acquisition in 2013. Management believes that these adjustments provide the Company and its investors with an indication of our baseline performance excluding items that are not considered to be reflective of our ongoing results. Management does not intend results excluding the adjustments to represent results as defined by GAAP, and the reader should not consider it as an alternative measurement calculated in accordance with GAAP, or as an indicator of the Company's performance. Accordingly, the measurements have limitations depending on their use. As Barnes Group does not predict special items that may occur in the future, and because our outlook is developed at a level of detail different than that used to prepare GAAP-based financial measures, we do not provide reconciliations to GAAP of our forward-looking financial measures.
