Transaction Rationale • Strengthens NCI’s position as a leader in the North American insulated metal panel (IMP) market • Management has not yet determined in which segment or segments the results of the CENTRIA business will be included following the acquisition • Management estimates that, for NCI’s fiscal 2014, combined panel product sales by the Metl - Span and CENTRIA businesses would have contributed approximately $381M of revenue (with an estimated Adjusted EBITDA margin of approximately 10 %) on a combined basis for NCI’s fiscal 2014 • Complements existing IMP offering in cold storage and commercial and industrial applications by expanding capabilities into the high - end architectural panel market with a well - recognized brand • Enables NCI to expand into serving mid - and high - rise non - residential applications • Accelerates NCI’s architectural panel expansion initiative • Existing, longstanding partnerships with leading architects that specify CENTRIA’s innovative product offerings in the early design phase • Insulated panel market in North America has potential to grow faster than the overall market • North American IMP market remains underpenetrated (~ 4 %). Management believes the penetration rate in Europe is approximately 5x the penetration rate in North America • Overall non - residential market still has significant runway for recovery (2014E non - res starts in square footage are ~29% below long - term average and ~17% below the average of the previous five cyclical troughs) • Adds complementary, proprietary coating capabilities for niche customer segments not currently served by NCI • Significant earnings upside potential from synergies, as well as any market rebound • Cost synergies estimated at ~$6M, with additional revenue synergy opportunities • C urrent CENTRIA Adj. EBITDA is ~$23M for the twelve months ended 9/30/2014, and is well below historical peak of $ 41M (CY 2009) • Meaningful near - term cash and earnings benefits • Tax step - up is expected to generate ongoing deductions that reduce effective tax rate and benefit cash flow 4

Management believes there is a significant opportunity to convert curtain wall, precast, EIFS/stucco, and brick projects to high - end IMPs • The IMP penetration rate in North America is only ~ 4 %. Management believes the IMP penetration rate in Europe is approximately 5x that of North America, implying significant runway for increased penetration Source: M anagement estimate based on industry information Square Feet (in millions) Source: McGraw - Hill 5 2014 2019 Total Wall CAGR 4.9% IMP CAGR 7.2%
