New Times and Challenges ...

• From now on, Paranapanema will experience a new phase given the conclusion of an important financial, tax and corporate restructuring process, the company has achieved:

financial strength focus on profitability focus on quality focus on technology  Strategy:1. Investment focused on: gains of scale and competitiveness•  Strong organic growth cycle from 2009 (cathod and Bus Bar expansion)•  Investment Plan approved for the  Border of Directors with longer maturity terms •  Capex 2010-2013 will be of  R$702 million assigned to: 20% expansion in refined copper production capacity  Expansion of over 50% in the production of semi-manufactured copper products (tubes and rolled products)•  Copper recycling:  improvement of concentrate and scrap mix , aiming at changing from a ratio of 83%/17% in 2010 to 

70%/30% by 2012• Precious metals plant (gold and silver)2. Projects: studies in progress for:•  Mineral rights:  In 2011, studies will be conducted on Paranapanema’s 105 mineral rights registered with DNPM, which 

includes  tin  ore,  copper,  chrome,  lead,  tin  alloy,  molybdenum,  gold,  silver,  nickel,  titanium  and  zinc  reserves,  among others,  aiming  at  checking  the  size  of  reserves  and  exploration  possibilities  in  the  States  of  Amapá,  Pará,  Roraima, Rondônia and Rio Grande do Sul.

Copper Demand Drivers and per capita consumption

Correlated to …  GDP growth   Global consumption   Growth of emerging countries  

Increase in investment infrastructure

Real estate and civil construction markets

Emergent countries ‘ growth above the global average

Increase in the use of clean energy(solar, wind and ethanol)

Transportation and automotive sectors

• The Brazilian economy will grow at an accelerated pace  that  may  exceed  5%,  but  in  a  sustainable manner.

•  Copper production chain has reported consumption growth from 1% to 2% above the Brazilian growth average. 

•  Local and foreign direct investment in Brazil, which ceased to be “the country of future” to be “the country of present”.

Global Refined Copper Indicators

• Recovery of cathode premiums vs. copper prices on LME – London Metal Exchange,  expected    for  2011, compared with 2010

• The Treatment Charge (TC) and the Refining Charge (RC)  correspond  to  the  deduction  of  the  discount allowed by miners to refiners on the metal prices on LME

• Average copper prices have been highly volatile   (offer  and  demand  plus  hedge  funds),  having 

increased at an average rate of  46% in 2010 against  2009

• The shutdown/interruption of activities  of smelters in China and  India  favored  the  increase  in TC/RC on the sport market in the second half of 2010

• Prices of refined copper by-products (gold,  silver and sulphuric acid) are also relevant indicators

MINING

•Copper extraction from mines;

•Copper ore contents between (0.5% and 2%);

•Processed at the mine, it is transformed into copper concentrate with about 30% of copper, 30% of sulphur, in addition to gold, silver and other elements.

•75% equity purchased on the foreign market (Chile).

FOUNDRY AND REFINING

•Copper concentrate is processed in the foundry, resulting in 99.5% pure anode.

•The electrolytic refining process transforms anodes into 99.99% pure cathodes (purity  needed to obtain optimal electrical features).

PRODUCTION OF DE SEMI-MANUFACTURED COPPER PRODUCTS AND COPPER ALLOYS

• SEMI-MANUFACTURED PRODUCTS

• Continuous lamination process; 

• Products: laminates, bars, wires, seamless tubes and stretched copper wires and copper alloys  (fed by cathodes and scrap);

• Copper alloys + zinc = brass; 

• Copper alloys + tin = bronze.

• MANUFACTURED PRODUCTS

• Products with highest added value ;

• Tubes, connections and “hidrolar” used in civil construction. 

LOGISTICS

•Distribution of Paranapanema  and Eluma copper products through the CDPC(Copper Products Distribution Center) – Itatiaia – State of Rio de Janeiro,  to the Southeast, South and Mid-West Regions;

Outlook for the Fertilizers Sector

New outlook from 2010 on• Sector consolidated with  the arrival of Vale  to  the  fertilizers sector, with  the production of 

phosphated  products  through  acquisitions,  and  operating  only  industrial  sales:  Fosfertil, Bunge, Mosaic and Yara;

• Repositioning of main market players with Bunge operating just as a mixer, Yara and Mosaic concentrated on reselling imported products;

• Recovery  of  the  sector  in  2010,  both  in  volumes  and  margins,  getting  closer  to  the production record reported in 2007;

• Brazilian GDP rose 7.5% and agricultural sector add to it 6.5% in 2010; • The GDP growth should level off in the next years in 5%;• Brazil like large exporter and producer of agricultural commodities such as cotton, sugarcane, 

soybeans,  corn,  coffee  and meat  benefited  for  increase  of  global  demand  and  population and shortage of farmlands in several countries;

• Estimative fertilizers consumption in Brazil boomed 6% for the 2011 based on harvest  grains trends 2010/11 and 2011/12.
