Corporate Structure Pursuant to the terms of its 2017 Senior Notes Mercer conducts operations through three subsidiaries: Rosenthal - Germany Stendal - Germany Celgar - BC, Canada The Corporation is divided into the "Restricted Group" and the "Non-Restricted Group" - a structure created to facilitate the acquisition of Celgar through the issue of senior notes (1) The Restricted Group is supported by the Celgar and Rosenthal operations The Non-Restricted Group is supported by the Stendal operation 100% Celgar - BC, Canada 100% Rosenthal - Germany 83% Stendal - Germany Restricted Group 520,000 ADMT + 100 MW 355,000 ADMT + 57 MW 650,000 ADMT + 102 MW the only two NBSK market pulp mills in Germany, which is Europe's largest market for NBSK pulp one of the largest, most modern pulp mills in North America Debt is 80% guaranteed by the German government Non-recourse to the Restricted Group

Significant Capacity with Access to Key Global Markets Mercer's three mills have a combined annual capacity of 1,525,000 air-dried metric tonnes (ADMT) of NBSK pulp production and 259 MW of electrical generation Following the finalization of Stendal's Project Blue Mill (ramp-up started at end of Q3 2013, expected finalization in November 2013), Mercer's electrical generating capacity will increase to 299 MW The mills' strategic locations position the company well to serve customers in Europe, North America and Asia In particular, China - the world's largest and fastest growing pulp import market - and Germany - the largest European pulp import market Celgar (B.C., Canada) 520,000 ADMT United States Stendal (Germany) 650,000 ADMT Rosenthal (Germany) 355,000 ADMT ^ Indonesia China Thailand Middle East Europe Japan ^ ^

(CHART) Growing Energy and Chemical By-Product Revenues Mercer has been a leader among paper and forest products companies in embracing the "bio-economy" and in harnessing significant value from the generation of surplus power as well as its production of bio-chemicals Mercer recognized the opportunity to secure new revenue streams from its operations, as the market place turned to biomass for carbon neutral power and renewable chemical by-products Since energy and chemical production is a by-product of our pulping process, our production is highly efficient and our energy and chemical sales are highly profitable Stendal's Project Blue Mill commenced in Q3 2013 (40 MW capacity addition) Green electricity and chemical by-product revenue... a significant and growing part of Mercer's business CAGR: 4.0% CAGR: 11.7% (CHART) CAGR: 20.4%

Mercer's Recent Developments Celgar Workforce Reduction Expected to improve fixed costs by €6.0 to €7.5 million per year Incurred pre-tax charges of ~€2.9 million for severance and other personnel related expenses in Q3 2013 Estimated additional costs in the range of €1.5 to €3.0 million (pre-tax) in Q4 2013 Stendal Credit Facilities Amortizing loan, supported by guarantees from the German Federal and State governments EBITDA based covenants pinch at the bottom of the pulp cycle The credit facilities were successfully amended in September 2013 to provide greater flexibility In connection with the amendment, Mercer injected US$20 million of capital in to the mill and increased equity ownership from 74.9% to 83.0% Working Capital Revolvers Rosenthal and Celgar's revolvers were extended to October 2016 and June 2016, respectively, on attractive terms Senior Notes Issued US$50 million tack-on at a 104.5% premium to face in July 2013 Stendal's Project Blue Mill Stendal's capital project involving production enhancements and the installation of 40 MW of new electrical generating capacity Started ramp-up phase in Q3 2013 on schedule and on budget

The NBSK Market

Introduction to the Major Themes in NBSK The impact of digital media on paper demand ? Current themes surrounding the NBSK market include: The effect of China and other emerging economies' continuing growth ? The net supply impact of mill closures, starts/restarts, and facility conversions ? The potential supply impact of integrated players selling their pulp on the market ?

After undergoing significant changes over the past 20+ years, the market for NBSK is trending from balanced to tight, with the meaningful substitution of NBSK for other pulps largely completed Putting NBSK's History into Perspective (CHART) Shortage! ? price surge Sources: Factset FOEX PIX Pulp NBSK (prices); PPPC (inventories) ^Supply, ^Prices: Stocks are low, prices increasing

NBSK Supply / Demand Summary Demand Fundamentals Supply Fundamentals Demand for NBSK is still growing globally Improving economic conditions for emerging countries Digital substitution Supply growth potential for NBSK is limited NBSK supply increases are limited due to fiber supply and the economics of integration Further conversions of NBSK capacity to dissolving pulp (DP) Aging mills With strong demand and flat supply, we believe the future NBSK market looks very attractive

Appendix C Reconciliation of Net Income to Operating EBITDA

Reconciling Net Income (Loss) to Operating EBITDA Note: For other reconciliations of Net Income (Loss) to Operating EBITDA in periods not shown here, please refer to that period's respective Form 10-Q or 10-K, which can be found on our website (www.mercerint.com) Operating EBITDA is defined as operating income (loss) plus depreciation and amortization and non-recurring capital asset impairment charges. Management uses Operating EBITDA as a benchmark measurement of its own operating results, and as a benchmark relative to its competitors. Management considers it to be a meaningful supplement to operating income (loss) as a performance measure primarily because depreciation expense and non-recurring capital asset impairment charges are not an actual cash cost, and depreciation expense varies widely from company to company in a manner that management considers largely independent of the underlying cost efficiency of their operating facilities. In addition, we believe Operating EBITDA is commonly used by securities analysts, investors and other interested parties to evaluate our financial performance. Operating EBITDA does not reflect the impact of a number of items that affect our net income (loss) attributable to common shareholders, including financing costs and the effect of derivative instruments. Operating EBITDA is not a measure of financial performance under the accounting principles generally accepted in the United States of America ("GAAP"), and should not be considered as an alternative to net income (loss) or income (loss) from operations as a measure of performance, nor as an alternative to net cash from operating activities as a measure of liquidity. Operating EBITDA has significant limitations as an analytical tool, and should not be considered in isolation, or as a substitute for analysis of our results as reported under GAAP. Operating EBITDA should only be considered as a supplemental performance measure and should not be considered as a measure of liquidity or cash available to us to invest in the growth of our business. Because all companies do not calculate Operating EBITDA in the same manner, Operating EBITDA as calculated by us may differ from Operating EBITDA or EBITDA as calculated by other companies. We compensate for these limitations by using Operating EBITDA as a supplemental measure of our performance and by relying primarily on our GAAP financial statements. in millions, except for per share data 2011 2012 Q3-2012 Q3-2013 Net Income (Loss) Attributable to Common Shareholders €50.1 (€12.2) (€9.7) (€2.2) Add: Net Income Attributable to Non-Controlling Interest €3.9 €1.7 €0.6 €0.5 Add: Income Tax Provision (Benefit) (€0.7) €7.3 €1.9 €0.9 Add: Interest Expense €59.0 €55.8 €14.1 €13.0 Add: Loss (Gain) on Derivative Instruments €1.4 (€3.7) €0.9 (€2.0) Add: Other Expense (Income) (€2.6) €0.1 (€0.6) (€0.1) Operating Income €111.1 €49.0 €7.2 €10.1 Add: Depreciation and Amortization €56.0 €58.1 €15.1 €14.7 Operating EBITDA €167.1 €107.1 €22.3 €24.8
