BSK Tightening of Supply and Demand Total Bleached Softwood Kraft demand in 2007 was 22.2 million tonnes, up from 21,9 million the year before.

NBSK Tightening of Supply and Demand The gap between supply and demand widened slightly in 2007 We had expected in 2007 the supply / demand spread to narrow to zero with the 1.2 million tonnes in capacity closures, but swing capacity and debottlenecking offset the closures. Based upon species mix in forests we believe capacity that has swung to NBSK can’t be sustained over the long term. Limitations to fiber switching coupled with continued NBSK demand growth and further capacity closures will continue to tighten fundamentals, leading to higher prices over the long term Historic NBSK Demand versus Practical Maximum Capacity Capacity (tonnes)Demand (tonnes)Demand Capacity Spread (%) 16,00035% 14,00030% 12,00025% 10,00020% 8,00015% 6,00010%Demand 000’s of tonnes 4,0005%Supply exceed 2,0000% 0-5% 04 5 6 7 999 00 01 02 03 0 0 0 0 90 0 0 0 20 20 20 20 191995199619971998 1 2 2 2 2 14 Source: Pulp & Paper Products CouncilYear

NBSK Substitution – SBSK / Radiata Is substitution to Southern softwood or Radiata a threat? There are quality and production issues associated with using greater volumes of southern softwood The coarseness of these fibers is such that it is difficult to increase the volume used without having sufficient installed refining capacity for conversion. Even still, converted Southern fiber only provides the base, not the necessary tensile strength There will be less and less Radiata production as competition for land use will favour eucalyptus instead of pine as pine takes too long to grow for its delivered yield In Europe, Mercer’s ability to provide very favourable shipping times relative to Southern producers provides a consistent and flexible supply solution for customers, ensuring strong relationships going forward

Short Term SBSK Swing Demand and Capacity Impacts SBSK Capacity is being sold at distressed prices Arauco’s Valdivia mill has been allowed to increase to full production Lee & Man’s 210,000 tonne Samoa mill has swung its unbleached capacity to bleached and is selling its lower quality fiber with significant discounts IP’s Southern Softwood Bastrop mill converted 450,000 tonnes of integrated capacity to market pulp (selling pulp in roll form) These new supplies of SBSK have been creating pricing competition in the lower quality softwood pulp segments. It is especially prevalent with the heavily discounted pulp being sold in rolls rather than sheets which is th e accepted format for all modern paper pulp machines Softwood swing demand utilizing SBSK capacity The Chinese market as a whole is less quality conscious. Some paper makers in China with less exacting standards have been able to substitute NBSK with SBSK/Radiata producing products for niches that require less quality. Net Impact: There has been a distortion in softwood fiber pricing in China and will only last until these supplies are absorbed into the ever increasing Chinese fiber demand

NBSK Swing Capacity is Causing Disruptions Low fiber availability is forcing swing Russian export duties and two warm winters in a row have significantly impacted Scandinavian hardwood log supplies Finnish pulp producers have swung significant hardwood capacity to softwood and as spot market sellers had been selling NBSK at discounts to move volume Finnish swing production is not sustainable over the long term Recent curtailment announcements by Botnia and Stora Enso indicate practical limits have been reached Stora Enso announced that, as a result of wood shortages, it is taking NBSK cur tailments at Sunila and Norrsundet this summer and that Norrsundet will only run at half capacity until its permanent closure at the end of the year Stora’s Enocell mill is switching its large line back to birch as long as supplies last The Swedish pulp sector had swung heavily to softwood after major storms created blow down a few years ago. These surplus volumes of softwood should now have been used up Net Effect: Scandinavian mills have been producing more softwood than traditionally, distorting softwood fundamentals; Increase in low priced NBSK swing capacity sales in regions like China had been negatively impacting NBSK producers

NBSK Substitution — Hardwood How much substitution from hardwood to softwood can be expected? Substitution between BEK and NBSK, which is mainly in the uncoated printing and writing segment, is a function of the pricing differential between the two — the more expensive one fiber becomes relative to the other, the more of the other fiber will be used, within the operational limits of the paper machine When the price differential exists for a prolonged period of time, we start seeing the practical substitution limits – producers trying to use more hardwood in their furnish fail to get reliab ility out of their machines Unless paper producers willingly slow down their machines significantly, very little change in the level of substitution is expected In North America, 90% of BEK is used in tissue, so the forecasted expansion in tissue of 3% will consume both BEK and NBSK Typical modern tissue requires a minimum of 30% NBSK in the furnish Northern and Southern mixed hardwoods are falling under increasing pressure due to high fiber, production and transportation costs to Europe and Asia

Evidence suggests over the ST, ability for easy substitution has been nearly exhausted as further reductions would impede the reliability of paper machines A rapid build up in consumption growth in the last half of 2007 has resulted in a consumption decline in the first half of 2008. This reflects the sector’s year over year average growth

NBSK Fundamentals How will the slow down of global growth affect NBSK demand? A general slow down of the global economy, coupled with changes in paper utilization due to e-commerce and the internet, will certainly translate into less production/consumption of certain paper segments – notably the coated and uncoated wood free sectors In order to mitigate the effects of these declining sectors, Mercer is focusing on the growing tissue segment and other higher end producers who value our quality and premium reinforcement characteristics What effect will the restructuring of the paper industry have on NBSK demand? The closure of 3-6 million tons of Chinese pulp and paper capacity — derived from highly polluting straw mills – will be beneficial for hardwood, recycle and NBSK demand As further restrictions are imposed, older smaller paper machines will be tightly squeezed, leaving the new high-speed machines that use NBSK running A weak USD, falling North American demand and poor economic performance is forcing the closure of non-competitive paper capacity, especially in Europe This is not expected to si gnificantly reduce demand for NBSK because some of these closures rely on integrated, rather than market, pulp and because a similar volume of paper will be produced, just by a smaller number of producers Tissue will continue to be an important growth segment for NBSK 20

Transition to Bio-energy Economics Pulp in a Carbon World Unless there is a change in how customers value forest or wood based products, the industry will not continue in its current state, creating capacity decline which will continue to affect supply and demand fundamentals until prices rise high enough to reflect the energy value of wood Over time, a levelling of the playing field on wood cost will occur between Northern and Southern mills as the cost of land for plantations is driven up by higher value products competing On a global basis, wood will reflect and possibly exceed its fossil fuel energy value, reflecting the carbon neutrality of wood Mercer’s position as a large net exporter of bio-energy puts it in a unique position to benefit from this opportunity

Advantageous financial structure Mercer’s levered capital structure is highly beneficial German Government provided Mercer € 375 million in grants for the construction of the Rosenthal and Stendal mills. This amount is credited against fixed assets and translates into € 375 million in equity or debt that the company did not have to raise Mercer’s € 565 million Stendal debt is 80% guaranteed by the German Governme nt, is fixed at an interest rate of approximately 5.3% plus margins and costs, and is secured by the mill’s own assets The debt has provisions for cross-currency swaps with no required margins It is an amortizing debt with no immediate balloon payments Our principal payments are effectively made in pre-tax dollars due to Mercer’s tax shields Unsecured convertible debt of USD $67.5 million at 8.5% with a conversion factor of 7.75; redeemable by the company starting Oct. 15th, 2008, maturing Oc t. 15th, 2010 Unsecured senior notes of USD $310 million at 9.25%, maturing Feb. 15th, 2013
