4 Why We Invested in TKR Successful transformation of Bearings business which now generates high levels of returns and cash flows Specialty Steel business has superior financial characteristics with upside opportunities Timken’s share price does not reflect the indicated trading values of TKR’s Bearings and Specialty Steel businesses Clear path to remove share price discount by separating the Steel business to allow the market to independently value TKR’s Bearings business

Cap. + Net Debt + Net Pension Liability)/(EBITDA + Pension Expense – Service Cost) EV/FCF = (Mkt. Cap. + Net Debt + Net Pension Liability)/(CFO + Excess Pension Contributions – Normalized CapEx + After-Tax Interest Expense) 2013 excess pension contribution assumptions are: TKR = $220M, SKF = $101M, CRS = $50M, ATI = $100M. Excess contribution = (expected cash contribution – expected required contribution) Adjustments to 2013 consensus CapEx for above normal CapEx spend: TKR = $75M for continuous caster, CRS = $90M for Alabama plant, ATI = $200M for Pennsylvania plant , NUE = $300M for Louisiana plant Without CapEx adjustments, EV/FCF multiples are: TKR = 10.9x and Steel average = 28.7x.

Assumes Spin Date of 1/1/2013. Pension Addback = (Expected Pension Expense – Service Cost) The valuation discount is significant when compared to soft synergies of joint research and sales 2006A 2007A 2008A 2009A 2010A 2011A 2012E 2013E Bearings Revenue $3,648 $3,119 $3,350 $2,471 $2,802 $3,338 $3,452 $3,577 Bearings EBITDA w/ Allocated Corporate $279 $313 $421 $337 $480 $631 $661 $716 Incremental Corporate post Spin ($16) Post-Spin EBITDA $279 $313 $421 $337 $480 $631 $661 $700 Steel Revenue $1,472 $1,562 $1,852 $715 $1,360 $1,957 $1,908 $1,960 Steel EBITDA w/ Allocated Corporate $248 $255 $288 ($23) $171 $289 $298 $312 Incremental Corporate post Spin ($8) Post-Spin EBITDA $248 $255 $288 ($23) $171 $289 $298 $304 EV/EBITDA Valuation 2013 Pension 2013 EBITDA Enterprise Equity Val.

Conclusions Valuation discount versus peers is significant, reflecting the market’s clear preference for pure-play bearings or steel alternatives Performing through a cycle will not correct this discount Soft synergies, including joint research and selling, are negligible when compared to the market discount Social impact of separation are insignificant Timken name survives on both companies Timken family ownership/Board representation continues at both companies Separation supports continued compensation of Chairman at Specialty Steel company Both company headquarters can remain in Canton 9
