Table of Contents
ALCOA INC. 
 
Formed in 1888 under the laws of the Commonwealth of Pennsylvania, Alcoa has its principal office in Pittsburgh, Pennsylvania. As used in this prospectus, “Alcoa” means Alcoa and its consolidated subsidiaries unless the context otherwise requires. 
 
Alcoa is the world’s leading producer of primary aluminum, fabricated aluminum and alumina, and is active in all major aspects of the industry: technology, mining, refining, smelting, fabricating and recycling. Alcoa serves the aerospace, automotive, packaging, building and construction, commercial transportation and industrial markets. Aluminum and alumina represent approximately two-thirds of Alcoa’s revenues, and the price of aluminum influences the operating results of Alcoa. Nonaluminum products include precision castings, industrial fasteners, vinyl siding, consumer products, food service and flexible packaging products, plastic closures, fiber optic cables, and electrical distribution systems for cars and trucks. 
 
Alcoa’s operations consist of five worldwide segments: Alumina and Chemicals, Primary Metals, Flat-Rolled Products, Engineered Products and Packaging and Consumer. Alcoa businesses that are not reported to management as part of one of these five segments are aggregated and reported as “Other.” 
 
Alumina and Chemicals—This segment consists of Alcoa’s worldwide alumina and chemicals system that includes the mining of bauxite, which is then refined into alumina. Alumina is sold directly to internal and external smelter customers worldwide or is processed into industrial chemical products. 
 
Primary Metals—This segment consists of Alcoa’s worldwide smelter system. Primary Metals receives alumina primarily from the Alumina and Chemicals segment and produces aluminum ingot to be used by Alcoa’s fabricating businesses, as well as sold to external customers, aluminum traders, and commodity markets. Results from the sale of aluminum powder, scrap and excess power are also included in this segment, as well as the results from aluminum derivative contracts. 
 
Flat-Rolled Products—This segment’s principal business is the production and sale of aluminum plate, sheet and foil. This segment includes rigid container sheet, which is used to produce aluminum beverage cans, and sheet and plate used in the transportation and distributor markets. 
 
Engineered Products—This segment includes hard- and soft-alloy extrusions, including architectural extrusions, super-alloy castings, steel and aluminum fasteners, aluminum forgings, and wheels. These products serve the transportation, building and construction, and distributor markets. 
 
Packaging and Consumer—This segment includes consumer products, foodservice, flexible packaging, and packaging graphics design, as well as closures and packaging machinery. The principal products in this segment include aluminum foil; plastic wraps and bags; metal and plastic beverage and food closures; flexible packaging; prepress services; and thermoformed plastic containers and extruded plastic sheet and film. Consumer products are marketed under brands including Reynolds Wrap®, Diamond®, Baco®, and Cut-Rite® wax paper. 
 
Other—This group includes other Alcoa businesses that are not included in the segments previously mentioned. This group includes Alcoa Fujikura Ltd., which produces electrical components for the automotive industry and fiber-optic cable and provides services for the telecommunications industry; the residential building products operations, Alcoa Home Exteriors (formerly Alcoa Building Products); automotive parts businesses; Thiokol, a producer of solid rocket propulsion systems (Thiokol was sold in April 2001.); and Reynolds’ metal distribution business, RASCO. (In November 2001, the net assets of RASCO were contributed to a joint venture, Integris Metals, Inc., in which Alcoa retains a 50% equity interest.) 
 
Alcoa is a global company operating in 40 countries. The principal executive offices of Alcoa are located at 201 Isabella Street, Pittsburgh, Pennsylvania 15212-5858 (telephone: (412) 553-4545).

Recent Developments 
 
On August 1, 2003, Alcoa completed the acquisition of the approximately 41% shareholding in Alcoa Alumínio S.A. (“Alcoa Alumínio”) and Alcoa Latin American Holdings Corporation (“ALAHC”) held by affiliates of Camargo Corrêa S.A. (“Camargo Corrêa”), a leading contractor and industrial conglomerate in Brazil (Camargo Corrêa and its affiliates collectively, the “Camargo Group”). Before the acquisition, Alcoa had owned approximately 59% of these South American operations. Alcoa and a wholly-owned subsidiary exchanged 17,773,540 shares of Alcoa common stock for all of the shares of common stock in Alcoa Alumínio and ALAHC held by the Camargo Group (the “Share Exchange”). Additional cash consideration tied to future performance of Alcoa Alumínio and ALAHC over the next five years may be payable by Alcoa under earn-out and guaranteed minimum payment formulas, but such additional consideration will be limited by notional dividends on and appreciation in the market price of Alcoa’s common stock during the same period. In connection with the Share Exchange, Alcoa agreed to register the resale of the 17,773,540 shares of Alcoa common stock by the selling shareholders. See “Selling Shareholders” and “Plan of Distribution.”

FORWARD-LOOKING STATEMENTS 
 
This prospectus and the documents incorporated by reference in this prospectus include certain statements that may be deemed to be “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by their use of words like “anticipates,” “believes,” “estimates,” “expects,” “hopes,” “should,” “targets,” “will,” “will likely,” “forecast,” “outlook,” “projects” and similar expressions, as they relate to Alcoa or the management of Alcoa. All statements that address expectations or projections about the future, including statements about Alcoa’s strategy for growth, cost reduction goals, expenditures and financial results, are forward-looking statements. Such statements reflect the views of Alcoa with respect to future events, the outcome of which is subject to certain risks and uncertainties. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results, performance or achievements of Alcoa may vary materially from those expressed or implied in the forward-looking statements. Alcoa disclaims any intention or obligation (other than as required by law) to update or revise any forward-looking statements. 
 
In addition to the factors discussed in Management’s Discussion and Analysis of Financial Condition and Results of Operations in Alcoa’s Form 10-K for the fiscal year ended December 31, 2002 and its Form 10-Q’s for the fiscal quarters ended March 31, 2003 and June 30, 2003, the following are some of the important factors that could cause Alcoa’s actual results, performance or achievements to differ materially from those projected in any forward-looking statements: 
 
 	•	 	Alcoa is a leading global producer of alumina, aluminum ingot and aluminum fabricated products. The aluminum industry is highly cyclical, with prices subject to worldwide market forces of supply and demand and other influences. Prices can be volatile. Although Alcoa uses contractual arrangements with customers, as well as forward, futures and options contracts, to manage its exposure to the volatility of London Metal Exchange-based prices, and is product and segment diversified, Alcoa’s results of operations could be affected by material adverse changes in economic or aluminum industry conditions generally or in the markets served by Alcoa, including the transportation, building, construction, distribution, packaging, industrial gas turbine, telecommunications and other markets. 	
 
 	•	 	Alcoa consumes substantial amounts of energy in its operations. Although Alcoa generally expects to meet the energy requirements for its alumina refineries and primary aluminum smelters from internal sources or from long-term contracts, the following could affect Alcoa’s results of operations: 	
 
o    significant increases in electricity costs rendering smelter operations uneconomic; 
o    the unavailability of electrical power due to droughts; 
o    interruptions in energy supply due to equipment failure or other causes; or 
o    the inability to extend contracts upon expiration on economical terms. 
 
 	•	 	Alcoa’s ability to grow earnings will be affected by increases in the cost of raw materials, including caustic soda, calcined petroleum coke and resins, in addition to energy. Alcoa may not be able to offset fully the effects of higher raw material costs through price increases or productivity improvements. 	
 
 	•	 	As part of its strategy for growth, Alcoa has made and may continue to make acquisitions and divestitures and form strategic alliances. There can be no assurance that these will be completed or beneficial to Alcoa. 	
 
 	•	 	Alcoa has investments and activities in numerous countries outside the U.S. and in emerging markets, including China, Brazil, India, Korea and Mexico. Changes in the laws or governmental policies in the countries in which Alcoa operates could affect its business in such countries and Alcoa’s results of operations. In addition, economic factors, including inflation and fluctuations in foreign currency exchange rates and interest rates, and competitive factors in the countries could affect Alcoa’s revenues, expenses and results of operations. 	
 
 	•	 	The markets for most aluminum products are highly competitive. In addition, aluminum competes with other materials, such as steel, plastics and glass, among others, for various applications in Alcoa’s key markets. The willingness of customers to accept substitutions for the products sold by Alcoa, the ability of 	
 
6 

Table of Contents
large customers to exert leverage in the marketplace to affect the pricing for fabricated aluminum products or other developments by or affecting Alcoa’s competitors or customers could affect Alcoa’s results of operations. 
 
 	•	 	A significant downturn in the business or financial condition of a key customer or customers supplied by Alcoa could affect Alcoa’s results of operations in a particular period. 	
 
 	•	 	Alcoa has undertaken and may continue to undertake productivity and cost-reduction initiatives to improve performance, including deployment of company-wide business process models, such as the Alcoa Business System and the Alcoa Enterprise Business Solution, an initiative designed to build a common global infrastructure across Alcoa for data, processes and supporting software. There can be no assurance that these initiatives will be completed or beneficial to Alcoa or that any estimated cost savings from such activities will be realized. 	
 
 	•	 	Alcoa is working on new developments in advanced smelting process technologies, including inert anode technology. There can be no assurance that such technologies will be commercially feasible or beneficial to Alcoa. 	
 
 	•	 	Alcoa’s operations worldwide are subject to numerous complex and increasingly stringent environmental laws and regulations. The costs of complying with such environmental laws and regulations, including participation in assessments and cleanups of sites, as well as internal voluntary programs, are significant and will continue to be so for the foreseeable future. Alcoa’s results of operations or liquidity in a particular period could be affected by certain environmental matters, including remediation costs and damages related to several sites. 	
 
 	•	 	Alcoa’s results of operations or liquidity in a particular period could be affected by significant legal proceedings or investigations adverse to Alcoa, including product liability, safety and health and other claims. 	
 
 	•	 	Alcoa’s estimates of liabilities and expenses for pensions and other postretirement benefits incorporate significant assumptions including the rate used to discount the future estimated liability, the long-term rate of return on plan assets and several assumptions relating to the employee workforce (salary increases, medical costs, retirement age and mortality). Alcoa’s results of operations, liquidity or shareholders’ equity in a particular period could be affected by a decline in the rate of return on plan assets, the rate used to discount the future estimated liability or changes in employee workforce assumptions. 	
 
 	•	 	Alcoa has projected a likely range of proceeds from the divestiture of the businesses and operations announced in the fourth quarter of 2002. There can be no assurance that Alcoa will realize the projected amount of proceeds from such divestitures. 	
 
 	•	 	War or terrorist activities may increase the cost of doing business or otherwise impact Alcoa’s financial performance. 	
 
The above list of important factors is not all-inclusive or necessarily in order of importance.

USE OF PROCEEDS 
 
All shares of common stock offered by this prospectus will be sold by the selling shareholders. Alcoa will not receive any of the proceeds from such sales. 
 
DESCRIPTION OF COMMON STOCK 
 
Alcoa’s common stock is registered under the Exchange Act and listed on the New York Stock Exchange. The following description of the common stock contains summaries of, and is subject to the detailed provisions of, Alcoa’s Articles of Incorporation and By-Laws and to the relevant provisions of the Pennsylvania Business Corporation Law (“PBCL”). 
 
Alcoa is authorized to issue 1,800,000,000 shares of common stock, par value $1.00 per share. As of August 4, 2003, there were 864,339,241 shares of Alcoa common stock outstanding. In addition, as of the same date, there were 60,235,297 shares of Alcoa common stock issued and held in Alcoa’s treasury, and 105,469,823 shares of Alcoa common stock reserved for issuance under various incentive plans. 
 
Dividend Rights 
 
Holders of Alcoa common stock will receive dividends when and as declared by Alcoa’s board of directors. However, no dividend will be declared or paid on the common stock if any Alcoa preferred stock is outstanding, unless all dividends accrued on all classes of Alcoa preferred stock and the current quarter yearly dividend on Alcoa’s $3.75 Cumulative Serial Preferred Stock have been paid or declared and a sum sufficient for payment has been set apart. 
 
Voting Rights 
 
Holders of Alcoa common stock have one vote per share. 
 
Liquidation Rights 
 
Upon any liquidation, dissolution or winding up of Alcoa, whether voluntary or involuntary, after payments to holders of Alcoa preferred stock in an amount determined by the board of directors of Alcoa, plus any accrued dividends, Alcoa’s remaining assets will belong to and will be divided among the holders of Alcoa common stock. Under Alcoa’s Articles of Incorporation, neither the consolidation or merger of Alcoa with or into one or more corporations or any share exchange or division involving Alcoa under applicable law will be deemed a liquidation, dissolution or winding up of Alcoa. 
 
Preemptive or Other Subscription Rights 
 
Holders of Alcoa common stock have no preemptive right to subscribe for any securities of Alcoa. 
 
Conversion and Other Rights 
 
No conversion, redemption or sinking fund provisions apply to Alcoa common stock, and Alcoa common stock is not liable to further call or assessment by Alcoa. All issued and outstanding shares of Alcoa common stock are fully paid and non-assessable. 
 
Other Matters 
 
Alcoa’s Articles of Incorporation provide for the following: 
 
 	•	 	a classified board of directors with staggered three-year terms; 	
 
 	•	 	special shareholder voting requirements to remove directors; and 	
 
8 

Table of Contents
 	•	 	certain procedures relating to the nomination of directors, filling of vacancies and the vote required to amend or repeal any of these provisions. 	
 
Alcoa’s Articles of Incorporation also prohibit Alcoa’s payment of “green-mail,” that is, payment of a premium in purchasing shares of its common stock from a present or recent holder of 5% or more of the common stock, except with the approval of a majority of the disinterested shareholders. This provision and the classified board provision may be amended or repealed only with the affirmative vote of at least 80% of the common stock. In addition, the Articles of Incorporation limit or eliminate to the fullest extent permitted by Pennsylvania law, as from time to time in effect, the personal liability of Alcoa’s directors for monetary damages, and authorize Alcoa, except as prohibited by law, to indemnify directors, officers, employees and others against liabilities and expenses incurred by them in connection with the performance of their duties to Alcoa. The classified board article provision and the anti-“greenmail” provision may have certain anti-takeover effects. 
 
Alcoa is governed by certain “anti-takeover” provisions in the PBCL. Chapter 25 of the PBCL contains several anti-takeover provisions that apply to registered corporations such as Alcoa. Section 2538 of the PBCL requires shareholder approval for certain transactions between a registered corporation and an interested shareholder (generally, a shareholder who owns 20% of the stock entitled to vote in an election of directors). Section 2538 applies if an interested shareholder (together with anyone acting jointly with such shareholder and any affiliates of such shareholder): 
 
 	•	 	is to be a party to a merger or consolidation, a share exchange or certain sales of assets involving such corporation or one of its subsidiaries; 	
 
 	•	 	is to receive a disproportionate amount of any of the securities of any corporation which survives or results from a division of the corporation; 	
 
 	•	 	is to be treated differently from others holding shares of the same class in a voluntary dissolution of such corporation; or 	
 
 	•	 	is to have his or her percentage of voting or economic share interest in such corporation materially increased relative to substantially all other shareholders in a reclassification. 	
 
In such a case, the proposed transaction must be approved by the affirmative vote of the holders of shares representing at least a majority of the votes that all shareholders are entitled to cast with respect to such transaction. Shares held by the interested shareholder are not included in calculating the number of shares entitled to be cast, and the interested shareholder is not entitled to vote on the transaction. This special voting requirement does not apply if the proposed transaction has been approved in a prescribed manner by the corporation’s board of directors or if certain other conditions, including the amount of consideration to be paid to certain shareholders, are satisfied or the transaction involves certain subsidiaries. 
 
Section 2555 of the PBCL may also apply to a transaction between a registered corporation and an interested shareholder, even if Section 2538 also applies. Section 2555 prohibits a corporation from engaging in a business combination with an interested shareholder unless one of the following conditions is met: 
 
 	•	 	the board of directors has previously approved either the proposed transaction or the interested shareholder’s acquisition of shares; 	
 
 	•	 	the interested shareholder owns at least 80% of the stock entitled to vote in an election of directors and, no earlier than three months after the interested shareholder reaches the 80% level, 	
 
o    the majority of the remaining shareholders approve the proposed transaction; 
 
o    shareholders receive a minimum “fair price” for their shares in the transaction; and 
 
o    the other conditions of Section 2556 of the PBCL are met; 
 
9 

Table of Contents
 	•	 	holders of all outstanding common stock approve the transaction; 	
 
 	•	 	no earlier than 5 years after the interested shareholder acquired the 20%, a majority of the remaining shares entitled to vote in an election of directors approve the transaction; or 	
 
 	•	 	no earlier than 5 years after the interested shareholder acquired the 20%, a majority of all the shares approve the transaction, all shareholders receive a minimum fair price for their shares, and certain other conditions are met. 	
 
Under the PBCL, a person or group of persons acting in concert who hold 20% of the shares of a registered corporation entitled to vote in the election of directors constitutes a control group. On the occurrence of the transaction that makes the group a control group, any other shareholder of the registered corporation who objects can, under procedures set forth under the PBCL, require the control group to purchase his or her shares at “fair value,” as defined in the PBCL. 
 
The PBCL also contains certain provisions applicable to a registered corporation such as Alcoa which, under certain circumstances, permit a corporation to: 
 
 	•	 	redeem “control shares,” as defined in the PBCL; 	
 
 	•	 	remove the voting rights of control shares; and 	
 
 	•	 	require the disgorgement of profits by a “controlling person,” as defined in the PBCL. 	
 
The transfer agent and registrar for Alcoa common stock is Equiserve Trust Company, N.A.

Relationship with Alcoa 
 
The Camargo Group became the principal minority shareholder of Alcoa Alumínio in 1984. Immediately before the Share Exchange, Allpar owned approximately 29% of the common stock of Alcoa Alumínio and Trelawney owned approximately 12% of the common stock of Alcoa Alumínio and approximately 41% of the common stock of ALAHC. The aggregate ownership of Allpar and Trelawney in each of Alcoa Alumínio and ALAHC was approximately 41%. Over the years, senior Alcoa executives had ongoing contacts with the Camargo Group and met annually with representatives of the Camargo Group to review Alcoa Alumínio results, issues, plans for the future and strategic direction. Alcoa and/or one or more of its subsidiaries were also parties to shareholder agreements with the Camargo Group relating to Alcoa Alumínio and ALAHC. In connection with the Share Exchange, the shareholder agreements were terminated and Camargo Group representatives serving as directors and/or executive council members of the council of administration of Alcoa Alumínio resigned their positions. During the five-year earn-out payment period after the closing of the Share Exchange (until December 31, 2007), Alcoa has agreed that the

Camargo Group may have a non-voting observer attend meetings of the board of directors of Alcoa Alumínio for so long as such body is maintained and retains its current scope of authority. Alcoa has reserved the right to change or eliminate such body, but if the board of directors is replaced by a consulting board or other body having similar functions, the Camargo Group will be entitled to have an observer attend the meetings of such board or other body. Unless Alcoa and the Camargo Group agree otherwise, the Camargo Group’s observer will continue to be provided with, with respect to the period covered by the earn-out period, certain Alcoa Latin America financial information specified in the principal agreement, prepared and circulated monthly, and a reconciliation between certain financial statements and certain numbers included in the calculation of the earn-out (whether or not provided to the board of directors, consulting board or other similar body), as specified in the principal agreement. If the board of directors is eliminated without being replaced by a consulting board or other body having similar functions, the Camargo Group’s observer will be provided with, with respect to the period covered by the earn-out period, and in addition to the documents required in the previous sentence, reports prepared by each business unit for review and discussion with the Alcoa senior executives as part of the quarterly review process and access on a bi-monthly basis to the Alcoa Alumìnio chief financial officer. In any event, the observer will not participate in management or in the formulation, determination or direction of basic business decisions but will receive as to content and timing the same information and material relating to the business of Alcoa Alumínio as is provided to the other members of such board or body during such five-year period. 
 
In addition to the above-described relationships, Alcoa has worked and is continuing to work with the Camargo Group on hydroelectric and other projects in Brazil and throughout South America.

PLAN OF DISTRIBUTION 
 
Alcoa is registering the resale of the shares of common stock acquired by the selling shareholders in the Share Exchange. See “Alcoa Inc.—Recent Developments” and “Selling Shareholders.” Alcoa will not receive any of the proceeds from the sale of the shares by the selling shareholders. 
 
Under the principal agreement and the registration rights agreement, Alcoa agreed to register the resale of the shares by the selling shareholders. Alcoa agreed to use its reasonable best efforts to cause the registration statement of which this prospectus is a part to remain effective for the sale of the shares for a period of two years after August 1, 2003, or such shorter period as will terminate when all of the shares have been disposed of by the selling shareholders or may be disposed of without regard to the volume limitations imposed under Rule 144 under the Securities Act (but in any event not before the expiration of any longer period required under the Securities Act). Alcoa will pay all costs and expenses incidental to the registration of the shares, except that the selling shareholders will pay underwriting discounts and commissions and transfer taxes, if any, attributable to the sale of the shares and all fees and expenses of the selling shareholders’ counsel. Alcoa also agreed to indemnify each of the selling shareholders, each underwriter of any underwritten transaction and their respective officers, directors and affiliates for certain liabilities, including liabilities under the Securities Act. 
 
Subject to the transfer restrictions and right of first refusal of Alcoa under the principal agreement (see “Plan of Distribution—Transfer Restrictions and Right of First Refusal” below), the selling shareholders may sell the common stock offered by this prospectus in one or more of the following ways at various times: 
 
 	•	 	on the New York Stock Exchange or any other national securities exchange on which Alcoa common stock is traded; 	
 
 	•	 	in the over-the-counter market; 	
 
 	•	 	in privately-negotiated transactions; or 	
 
 	•	 	in a combination of such methods of sale. 	
 
The selling shareholders may sell their shares at: 
 
 	•	 	market prices prevailing at the time of the sale; 	
 
 	•	 	prices related to the then current market price; 	
 
 	•	 	negotiated prices; or 	
 
 	•	 	fixed prices. 	
 
In addition to selling the shares under this prospectus, the selling shareholders may: 
 
 	•	 	sell the shares under Rule 144 of the Securities Act rather than under this prospectus, if the transaction meets the requirements of Rule 144; or 	
 
 	•	 	transfer the shares in other ways not involving market makers or established trading markets, including directly by gift, distribution or other transfer; or 	
 
 	•	 	sell the shares by any other legally available means. 	
 
The selling shareholders may offer and sell their shares in any manner permitted by law, including through underwriters, brokers, dealers or agents, and directly to purchasers. The shares of common stock may also be sold in the following types of transactions: 
 
13 

Table of Contents
 	•	 	sales to underwriters who will acquire the shares for their own account and resell them in one or more transactions at fixed prices or at varying prices determined at the time of sale; 	
 
 	•	 	block transactions in which the broker or dealer engaged will attempt to sell the shares as an agent but may position and resell a portion of the block as a principal to facilitate the transaction; 	
 
 	•	 	purchases by a broker or dealer as principal and resale by such broker or dealer for its account; 	
 
 	•	 	ordinary brokerage transactions and transactions in which a broker solicits purchasers; 	
 
 	•	 	an exchange distribution in accordance with the rules of any such exchange; 	
 
 	•	 	transactions between sellers and purchasers without a broker-dealer; 	
 
 	•	 	sales directly to institutional investors; or 	
 
 	•	 	sales through agents to the public or to institutional investors. 	
 
In effecting sales, brokers or dealers engaged by the selling shareholders may arrange for other brokers or dealers to participate in the resales. 
 
In connection with the distribution of the shares, a selling shareholder may enter into hedging transactions with broker-dealers. In connection with such transactions, broker-dealers may engage in short sales of the shares in the course of hedging the positions they assume with the selling shareholder. A selling shareholder may also sell the shares short and redeliver the shares to close out the short positions. A selling shareholder may also enter into option or other transactions with broker-dealers, which require the delivery of the shares to the broker-dealer or an affiliate thereof. A selling shareholder may also loan or pledge the shares to a financial institution, broker-dealer or an affiliate thereof, who may sell the loaned shares or upon a default in the case of a pledge, sell the pledged shares. In addition to the foregoing, a selling shareholder may enter into, from time to time, other types of hedging transactions. 
 
Certain persons participating in the distribution of the shares of common stock may engage in transactions that stabilize the price of the common stock. Under the rules and regulations under the Exchange Act, any person engaged in a distribution of the shares offered pursuant to this prospectus may be limited in its ability to engage in market activities with respect to those shares. The selling shareholders will be subject to the provisions of the Exchange Act and the rules and regulations under the Exchange Act, including Regulation M. Those rules and regulations may limit the timing of purchases and sales of any shares offered by the selling shareholders pursuant to this prospectus. 
 
Brokers, dealers or agents may receive compensation in the form of commissions, underwriting discounts or concessions from the selling shareholders and/or the purchasers in amounts to be negotiated in connection with the sale. The selling shareholders and any brokers or dealers or agents and any other participating brokers or dealers may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission, discount or concession, and any profit on the sale of the shares by the selling shareholders, may be deemed to be underwriting discounts or commissions under the Securities Act. The selling shareholders may also agree to indemnify any underwriter, broker-dealer or agent against certain liabilities related to the selling of the shares, including liabilities arising under the Securities Act. 
 
Alcoa has not been advised by the selling shareholders of any selling arrangement as of the date of this prospectus between any selling shareholder and any underwriter, broker-dealer or agent. 
 
At the time a particular offering of shares is made, to the extent required under the Securities Act, a prospectus supplement will be distributed, which will set forth the number of shares being offered and the terms of the offering, including the names of any underwriters, any discounts, commissions and other items constituting

compensation to the underwriters, broker-dealers or agents, the public offering price and any discounts, commissions or concessions allowed or paid by underwriters to dealers. 
 
Transfer Restrictions and Right of First Refusal 
 
The following summary of certain provisions of the principal agreement relating to the Share Exchange is not meant to be complete. For more information, you should refer to the full text of the principal agreement filed as an exhibit to the registration statement of which this prospectus is a part, including the definitions of terms used and not defined in this prospectus. 
 
Agreed Volume Limitation. Under the principal agreement, the Camargo Group and its affiliates may not, before June 1, 2008, effect any sale, assignment, pledge, transfer or other disposition (each, a “Transfer”), other than exempt Transfers as described below, of the shares of Alcoa common stock acquired in the Share Exchange in excess of the following agreed volume limitation: 
 
 	•	 	from August 1, 2003 until August 1, 2005, 900,000 shares per day; and 	
 
 	•	 	from August 1, 2005 until June 1, 2008, the greater of: 	
 
 	o	 	an amount of shares per day equal to 30% of the average daily trading volume of Alcoa common stock on the New York Stock Exchange during the 30 day period before the applicable day; and 	
 
 	o	 	900,000 shares per day. 	
 
If there is a change in the number of outstanding shares of Alcoa common stock as a result of a stock split, reverse stock split or similar Alcoa corporate action, the number 900,000 will be adjusted so as to maintain the relationship between such number and the number of outstanding shares of Alcoa common stock immediately before such action. 
 
The agreed volume limitation also applies to the sale of shares of Alcoa common stock by a hedging counterparty to establish its net initial hedge position with respect to a forward sale or other derivative transaction between the Camargo Group or its affiliates and such hedging counterparty involving shares of Alcoa common stock acquired in the Share Exchange (a “Monetization Arrangement”). As used in this prospectus, “initial hedge” means, with respect to any Monetization Arrangement, the sale of shares of Alcoa common stock by a hedging counterparty to establish its net initial hedge position with respect to such Monetization Arrangement in an amount not exceeding the aggregate number of shares of Alcoa common stock underlying such Monetization Arrangement multiplied by the initial delta (as determined by the hedging counterparty in a commercially reasonable manner) for such Monetization Arrangement. For the avoidance of doubt, the initial hedge will not include any sales of shares of Alcoa common stock made to dynamically adjust the hedging counterparty’s net initial hedge position with respect to any Monetization Arrangement. 
 
Right of First Refusal of Alcoa. Under the principal agreement, Alcoa has a right of first refusal in connection with: 
 
 	•	 	any Transfer of the shares of Alcoa common stock acquired in the Share Exchange by the Camargo Group or its affiliates that occurs on or before June 1, 2008, other than exempt Transfers as described below; and 	
 
 	•	 	any Transfer of Alcoa common stock occurring on or before June 1, 2008 that is made by a hedging counterparty to establish its net initial hedge position with respect to a Monetization Arrangement. 	
 
The purchase price for any shares of Alcoa common stock purchased by Alcoa in the exercise of its right of first refusal will equal the volume weighted average of the sales prices per share of Alcoa common stock on the New York Stock Exchange on the trading day on which the Camargo Group’s proposed sale notice becomes effective pursuant to the terms of the principal agreement, if Alcoa’s exercise notice is delivered to the Camargo Group at or before 1:00 p.m., New York City time, on such day, and otherwise on the subsequent trading day. The Camargo Group must also specify a minimum price per share at which the Camargo Group is willing to Transfer the shares, and a sale of the shares will not be consummated if the applicable price described in the foregoing sentence is below such minimum price. Such minimum price will be no greater than the closing price per share of Alcoa common stock on the New York Stock Exchange on the trading day immediately before the trading day on which the Camargo Group delivered its proposed sale notice to Alcoa in accordance with the right of first refusal provisions. 
 
Exempt Transfers. Under the principal agreement, the following Transfers of the shares of Alcoa common stock acquired in the Share Exchange by the Camargo Group and its affiliates are not subject to the agreed volume limitation or right of first refusal of Alcoa described above: 
 
15 

Table of Contents
(a)	 	Transfers to Camargo Corrêa Affiliates—any Transfer of such shares to Camargo Corrêa or any of its affiliates who execute an agreement confirming that any subsequent Transfer of such shares by such Camargo Corrêa affiliate before June 1, 2008 will be subject to the restrictions and obligations set forth in the principal agreement and registration rights agreement; 	
 
(b)	 	Transfers to Alcoa—any Transfer of such shares to Alcoa or any of its affiliates; 	
 
(c)	 	Alcoa Business Combinations—any Transfer of such shares in a tender offer, merger or other Alcoa business combination transaction involving Alcoa common stock; 	
 
(d)	 	Alcoa-Approved Limited Transfers—any Transfer (other than or in relation to a Monetization Arrangement) of such shares to a person (excluding the Camargo Group and its affiliates) who: 	
 
 	o	 	together with its affiliates, will not own, directly or indirectly, after giving effect to such Transfer, more than 1,800,000 shares of Alcoa common stock; and 	
 
 	o	 	has been approved by Alcoa. Alcoa will have the right to withhold such approval only for good reason. Good reason means a determination made by Alcoa in good faith and upon a reasonable basis that such exempt Transfer, when considered together with all other prior exempt Transfers, would reasonably be expected to materially adversely affect the market price for Alcoa common stock within a period of 15 trading days from the time that such proposed exempt Transfer would be effected, if approved, or reasonably could result in public sales of Alcoa common stock on a single trading day in excess of the agreed volume limitation described above; 	
 
(e)	 	Alcoa-Agreed Restricted Transfers—any Transfer (other than or in relation to a Monetization Arrangement) of such shares to a person (excluding the Camargo Group and its affiliates) who executes an agreement with Alcoa before such Transfer confirming that any subsequent Transfer by such person or its affiliates that occurs before June 1, 2008 will be subject to the agreed volume limitation and right of first refusal of Alcoa described above. The Camargo Group and its affiliates may not make more than two of these Transfers before June 1, 2008; 	
 
(f)	 	Long Term Alcoa Investor—any Transfer of such shares to a long term Alcoa investor who is an “accredited investor” within the meaning of Rule 501 of Regulation D under the Securities Act and who represents and warrants to Alcoa that: 	
 
 	o	 	it is acquiring the shares for investment purposes and not with a view to distribution thereof; 	
 
 	o	 	it has been a beneficial owner of Alcoa common stock at all times during the 180 day period before the date of the proposed Transfer, and is, as of such date, the beneficial owner of at least 1% of Alcoa’s then outstanding common stock; 	
 
 	o	 	during the 180 day period before the Transfer, it and its affiliates have not sold in the aggregate more than 30% of the number of shares of Alcoa common stock of which it and its affiliates were the beneficial owners as of the beginning of such 180 day period; and 	
 
 	o	 	it and its affiliates do not have any present intention to sell any of such shares or other shares of Alcoa common stock of which it or its affiliates are the beneficial owners; 	
 
(g)	 	Monetization Arrangements — any Transfer of such shares, directly or indirectly, to a hedging counterparty in connection with a Monetization Arrangement. Before making such Transfer, the Camargo Group or its affiliates must enter into an agreement with such hedging counterparty assuring that: 	
 
16 

Table of Contents
 	o	 	the hedging counterparty will not enter into any Monetization Arrangements with other financial institutions or other persons in connection with establishing its initial hedge; 	
 
 	o	 	before establishing its initial hedge, the hedging counterparty will grant Alcoa a right of first refusal with respect to the Alcoa common stock to be sold under such initial hedge on the same terms as the right of first refusal of Alcoa described above; 	
 
 	o	 	the hedging counterparty will not effect any initial hedge Transfers, or any Transfers in relation to the early termination of a Monetization Arrangement, on any day which, when aggregated with (i) all initial hedge Transfers, or any Transfers in relation to the early termination of a Monetization Arrangement, made or to be made on such day by all other hedging counterparties to which a Transfer has been made under this provision and (ii) any Transfers (other than exempt Transfers) made, or to be made, by the Camargo Group or its affiliates on such day, exceed the agreed volume limitation described above; 	
 
 	o	 	the maturity date of such Monetization Arrangement is such that after taking into account the maturity dates of all other Monetization Arrangements previously effected under this provision, there will not mature on any single day Monetization Arrangements that in the aggregate could result in sales of Alcoa common stock on any day in excess of the agreed volume limitation described above; and 	
 
 	o	 	the Monetization Arrangement will not mature before August 1, 2004; and 	
 
(h)	 	Pledges—any Transfer (other than or in relation to a Monetization Arrangement) of such shares to a bank or other financial institution as security for a loan or other financing, or upon foreclosure, so long as such bank or financial institution executes an agreement confirming that any subsequent Transfer of such shares by it or its affiliates that occurs before June 1, 2008 will be subject to the agreed volume limitation and right of first refusal of Alcoa described above. 	
 
Restrictions on Transferees. Persons who acquire shares of Alcoa common stock from the Camargo Group or its affiliates in exempt Transfers described in clauses (a), (e), (g) and (h) above will, in turn, be subject to the following restrictions under the principal agreement on the subsequent Transfer of such shares before June 1, 2008: 
 
 	•	 	if Camargo Corrêa or any of its affiliates obtain the shares in an exempt Transfer under clause (a) above (Transfers to Camargo Corrêa Affiliates), it (and any subsequent affiliate acquiring the shares in an exempt Transfer under such clause) will be subject to the restrictions in the principal agreement, including the agreed volume limitation and right of first refusal of Alcoa described above; 	
 
 	•	 	if the transferee obtains the shares in an exempt Transfer under clause (e) above (Alcoa-Agreed Restricted Transfers), it (and any subsequent transferee acquiring the shares in an exempt Transfer under such clause) will be subject to the restrictions in the principal agreement, including the agreed volume limitation and right of first refusal of Alcoa described above; 	
 
 	•	 	if the transferee is a hedging counterparty that obtains the shares in an exempt Transfer under clause (g) above (Monetization Arrangements), the following restrictions will apply: 	
 
 	o	 	it and its affiliates will be subject to the restrictions in the principal agreement, including the agreed volume limitation and right of first refusal of Alcoa described above, only with respect to initial hedge transfers (but not with respect to other transactions involving Alcoa common stock to manage its exposure under the Monetization Arrangement); and 	
 
 	o	 	it and its affiliates will be subject to the agreed volume limitation (but not the right of first refusal of Alcoa) described above with respect to sales of the shares of Alcoa common stock acquired in the Share Exchange by the Camargo Group or sales of other Alcoa common stock made at maturity or earlier termination of the Monetization Arrangement; and 	
 
 	•	 	if the transferee obtains the shares in an exempt Transfer under clause (h) above (Pledges), whether as collateral or upon foreclosure, it (and any subsequent transferee acquiring the shares in an exempt Transfer under such clause) will be subject to the restrictions in the principal agreement, including the agreed volume limitation and right of first refusal of Alcoa described above.

LEGAL MATTERS 
 
The validity of the shares of common stock offered by this prospectus has been passed upon for Alcoa by Denis A. Demblowski, Assistant General Counsel, of Alcoa. Mr. Demblowski is paid a salary by Alcoa, is a participant in various benefit plans offered by Alcoa to employees of Alcoa generally and beneficially owns, or has rights to acquire, an aggregate of less than 1% of Alcoa’s outstanding common stock. 
 
INDEPENDENT ACCOUNTANTS 
 
The consolidated financial statements and related schedule of Alcoa and its subsidiaries incorporated by reference in Alcoa’s Annual Report on Form 10-K for the fiscal year ended December 31, 2002, have been so incorporated in reliance on the reports of PricewaterhouseCoopers LLP, independent accountants, given on the authority of said firm as experts in auditing and accounting. 
 
With respect to the unaudited financial information of Alcoa for the three-month periods ended March 31, 2003 and 2002 and the three-month and six-month periods ended June 30, 2003 and 2002, incorporated by reference in this prospectus, PricewaterhouseCoopers LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated April 4, 2003 and July 8, 2003, except for Note Q, as to which the date is July 18, 2003, incorporated by reference herein, state that they did not audit and they do not express an opinion on that unaudited financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers LLP is not subject to the liability provisions of Section 11 of the Securities Act for their reports on the unaudited financial information because those reports are not “reports” or “parts” of the registration statement prepared or certified by PricewaterhouseCoopers LLP within the meaning of Sections 7 and 11 of the Securities Act.

Item 14.    Other Expenses of Issuance and Distribution. 
 
The following table sets forth the fees and expenses in connection with the offering and distribution of the shares of common stock registered under this registration statement, other than underwriting compensation. Alcoa will pay all of the costs identified below. All such expenses, other than the SEC registration fee, are estimates. 
 
SEC registration fee	  	$	38,082.24	
Printing expenses	  	 	25,000.00	
Accountants’ fees and expenses	  	 	20,000.00

Miscellaneous expenses	  	 	5,000.00	
		
Total	  	$	98,082.24	
 
Item 15.    Indemnification of Directors and Officers. 
 
Article V of the By-Laws of Alcoa provides that Alcoa shall indemnify, under specified circumstances, persons who were or are directors, officers or employees of Alcoa or who served or serve other business entities at the request of Alcoa. Under these By-Law provisions, a person who is wholly successful in defending a claim will be indemnified for any reasonable expenses. To the extent a person is not successful in defending a claim, reasonable expenses of the defense and any liability incurred are to be indemnified under these provisions only where independent legal counsel or another disinterested person selected by the board of directors determines that such person acted in good faith and in a manner such person reasonably believed to be in, or not opposed to, the best interests of Alcoa, and in addition with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct of such person was unlawful. Any expense incurred with respect to any claim may be advanced by Alcoa if the recipient agrees to repay such amount if it is ultimately determined that such recipient is not to be indemnified pursuant to Article V. 
 
The foregoing By-Law provisions generally parallel Sections 1741 and 1745 of the Pennsylvania Business Corporation Law (“PBCL”). Section 1746 and the By-Laws both also provide that the indemnification provided for therein shall not be deemed exclusive of any other rights to which those seeking indemnification may otherwise be entitled. 
 
Section 1746 of the PBCL and the By-Laws provide for increased indemnification protections for directors, officers and others. Indemnification may be provided by Pennsylvania corporations in any case except where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. 
 
Section 1713 of the PBCL also sets forth a framework whereby Pennsylvania corporations, with the approval of the shareholders, may limit the personal liability of directors for monetary damages except where the act or omission giving rise to a claim constitutes self-dealing, willful misconduct or recklessness. The section does not apply to a director’s responsibility or liability under a criminal or tax statute and may not apply to liability under Federal statutes, such as the Federal securities laws. 
 
Alcoa’s Articles of Incorporation and By-Laws were amended by the shareholders to implement the increased protections made available to directors under the PBCL as described in the preceding paragraph. Article VIII of the By-Laws provides that, except as prohibited by law, every director of Alcoa shall be entitled as of right to be indemnified by Alcoa for expenses and any and all liability paid or incurred by such person by reason of such person being or having been a director of Alcoa. Expenses incurred with respect to any claim may be advanced by Alcoa, subject to certain exceptions. The shareholders have also approved a form of indemnity agreement. Alcoa has entered into such an indemnity agreement with each of its current directors.

Table of Contents
Alcoa has purchased a three-year liability insurance policy with an aggregate limit of $150 million, with certain specified deductible amounts for liability of directors and officers and reimbursement to Alcoa for indemnification provided to directors and officers. The policy has an expiration date of October 1, 2003 and provides liability insurance and reimbursement coverage for Alcoa, and its directors and officers, which is permitted by the laws of Pennsylvania referred to above. 
 
The Articles of Incorporation provide that except as prohibited by law, Alcoa may indemnify any person who is or was a director, officer, employee or agent of Alcoa or is or was serving at the request of Alcoa as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including, without limitation, any employee benefit plan, and may take such steps as may be deemed appropriate by the board of directors, including purchasing and maintaining insurance, entering into contracts, including, without limitation, contracts of indemnification between Alcoa and its directors and officers, creating a trust fund, granting security interests or using other means, including, without limitation, a letter of credit to ensure the payment of such amounts as may be necessary to effect such indemnification. The By-Laws provide for indemnification of such persons to the fullest extent permitted by law. 
 
The Articles of Incorporation also provide that to the fullest extent that the laws of the Commonwealth of Pennsylvania permit elimination or limitation of the liability of directors, no director of Alcoa shall be personally liable for monetary damages for any action taken, or any failure to take any action. 
 
Under the registration rights agreement relating to the shares of Alcoa common stock registered under this registration statement, each of Alcoa and the selling shareholders have agreed under certain circumstances to indemnify each other, each underwriter of any underwritten transaction, and their respective directors, officers and affiliates for certain liabilities, including liabilities incurred under the Securities Act, in connection with the registration of the shares.

Item 17.    Undertakings. 
 
The undersigned Registrant hereby undertakes: 
 
(a)    (1)  To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: 
 
 	(i)	 	To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; 	
 
 	(ii)	 	To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and 	
 
 	(iii)	 	To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; 	
 
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. 
 
(2)    That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 
 
(3)    To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. 
 
(b) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 
 
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions described in Item 15 above, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

2.2 Acquisition of the Shares. The Shares will be acquired initially by the Camargo Group from the Alcoa Group in a private placement transaction under section 4(2) of the Securities Act. The Shares will be registered for resale by the Shelf Registration Statement, as more fully described in Section 2.3 and in the Registration Rights Agreement, attached hereto as Exhibit E and made a part hereof (the “Registration Rights Agreement”). If the Shares are delivered in certificated form at the Closing, then as soon as practicable following the Closing, the Camargo Group agrees to establish an account at Alcoa’s transfer agent, Equiserve Trust Company, N.A. 
 
5 

(“Equiserve”), to hold the Shares in book-entry form through the direct registration system to eliminate the need for physical certificates. 
 
2.2.1 The certificate(s) representing and/or the book entry account(s) evidencing ownership of the Shares by the Camargo Group shall be endorsed with legends substantially to the following effect: 
 
“The Shares represented by [this certificate] [this book-entry account] have not been registered under the Securities Act of 1933 and may not be transferred in the absence of such registration or an exemption therefrom under such Act. In addition, the Shares are subject to certain rights of first refusal and restrictions on transfer as provided in the Principal Agreement, dated as of July 25, 2003 among Alcoa Inc. and certain other signatories thereto and the Registration Rights Agreement, dated as of July 25, 2003 among Alcoa Inc. and certain other signatories thereto, copies of which are on file at the principal office of Alcoa Inc.” 
 
Insofar as such legends (a) relate to the Securities Act or any U.S. securities laws, such legends shall be removed as and when required pursuant to the terms of the Registration Rights Agreement, and (b) relate to the rights of first refusal and other contractual restrictions on transfer set forth in this Agreement, such legends shall, upon the request of the holder of such Shares, be removed and Alcoa shall issue a certificate without such legend or create a book-entry account without such legend, as the case may be, if such Shares are no longer subject to the rights of first refusal and other contractual restrictions on transfer as set forth herein. 
 
2.3 Shelf Registration. Alcoa shall (a) no later than 30 days after the Closing Date, prepare and file with the SEC a registration statement for the resale of the Shares in an offering to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act (or any similar rule that may be adopted by the SEC) (the “Shelf Registration Statement”), (b) use its reasonable best efforts to cause such Shelf Registration Statement to become effective as soon as practicable after such filing, but in all events within 120 days after the Closing Date, (c) use its reasonable best efforts to cause the Shelf Registration Statement to remain effective at all times thereafter until the second anniversary of the Closing Date or such shorter period as will terminate when all of the Shares have been disposed of by the Camargo Group and its Affiliates or may be disposed of without regard to the volume limitations imposed under Rule 144 (but in any event not before the expiration of any longer period required under the Securities Act) (the “Effectiveness Period”), (d) prepare and file with the SEC such amendments and supplements to the Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for the period specified in this sentence above, and (e) when requested by Camargo Corrêa, keep Camargo Corrêa reasonably apprised of the status of the Shelf Registration Statement prior to the expiration of the Effectiveness Period, all as more fully set forth in the Registration Rights Agreement. Alcoa acknowledges that the foregoing covenants have been determinative to the Camargo Group’s decision to consummate the Exchange. 
 
2.4 Transfer Restrictions and Right of First Refusal. 
 
2.4.1 Volume Limitation. Prior to the Restriction Termination Date, the Camargo Group and its Affiliates shall not effect any Transfer of Shares, other than Exempt Transfers made in accordance with Section 2.4.3, in excess of the Volume Limitation. The parties agree 
 
6 

that this provision shall apply regardless of whether, at the time of the proposed Transfer, the volume limitations imposed under Rule 144 under the Securities Act are applicable. 
 
2.4.2 Right of First Refusal. The parties agree that, subject to Section 2.4.3, Alcoa will have a right of first refusal, on the terms set forth below, (x) in connection with any sale, assignment, pledge, transfer or other disposition (each, a “Transfer”) of Shares by the Camargo Group or its Affiliates that occurs on or before the Restriction Termination Date and (y) in connection with any Transfer of Common Stock occurring on or before the Restriction Termination Date that is made by a Hedging Counterparty to establish the Initial Hedge (the “Initial Hedge Transfer”). Until the Restriction Termination Date, prior to the Camargo Group or its Affiliates making any Transfer of Shares, Camargo Corrêa will deliver to Alcoa no later than 9:00 a.m., New York City Time, on a Trading Day, a written notice (the “Proposed Sale Notice”) specifying the number of Shares proposed to be Transferred (which must be in compliance with the Volume Limitation), the name of the transferor, a description of how and when the proposed Transfer will take place, the date and time of the Exercise Deadline determined in accordance with the provisions of this Section 2.4.2 and, other than in connection with a sale to be effected directly by the Camargo Group or its Affiliates on a national securities exchange or in an underwritten public offering, identifying the price, the name of the proposed Transferee and all other material terms of the proposed Transfer. Until the Restriction Termination Date, prior to permitting a Hedging Counterparty to make an Initial Hedge Transfer, Camargo Corrêa will cause such Hedging Counterparty to deliver a Proposed Sale Notice to Alcoa at the same time and containing the information specified in the preceding sentence. A Proposed Sale Notice given (x) on or before 9:00 a.m., New York City Time, on a day that is a Trading Day shall be effective at 9:00 a.m. on such Trading Day, and (y) on a day that is not a Trading Day or after 9:00 a.m., New York City Time, on a Trading Day will be deemed to be effective at 9:00 a.m., New York City Time, on the next succeeding Trading Day. Such notice shall be in writing, shall be sent to Alcoa’s group president—Latin America and to its treasurer and general counsel as set forth in Section 7.6 of this Agreement. Alcoa shall have the right to acquire, or cause one or more of its designated Affiliate(s) to acquire all, but not less than all, of the Shares (or, in the case of an Initial Hedge Transfer, the Common Stock) identified in the Proposed Sale Notice for a price, payable in cash, equal to (x) the Average Price for the Trading Day on which the Proposed Sale Notice was effective if Alcoa delivers the applicable Alcoa Exercise Notice at or before 1:00 p.m. New York City Time on such Trading Day or (y) the Average Price for the Trading Day subsequent to the Trading Day on which the Proposed Sale Notice was effective if the Alcoa Exercise Notice is delivered prior to the Exercise Deadline but after 1:00 p.m. New York City Time on the day the Proposed Sale Notice was effective. The Trading Day on which the price for the Shares was determined in accordance with the foregoing sentence is referred to herein as the “Trade Date”. The Camargo Group shall (but this provision is personal to the Camargo Group and its Affiliates and shall not apply to any other Person) specify in its Proposed Sale Notice a minimum per Share price at which it is willing to Transfer the Shares (which shall be no greater than an amount equal to the closing price per share of Common Stock on the New York Stock Exchange (as reported by Bloomberg Financial Markets, or, if not reported thereby, by another authoritative source) on the Trading Day immediately prior to the Trading Day on which the Camargo Group delivered its Proposed Sale Notice and, if no minimum price is specified, shall be deemed to be an amount equal to the closing price per share of Common Stock on the New York Stock Exchange (as reported by Bloomberg Financial Markets, or, if not reported thereby, by another authoritative source) on the Trading Day immediately prior to the Trading Day on which the Camargo Group delivered its Proposed Sale Notice), and if the applicable Average Price determined in accordance with this Section is less 
 
7 

than such minimum price, then such Proposed Sale Notice shall be deemed null and void immediately and automatically without further action or notice required by either party. To exercise its right of first refusal, Alcoa shall deliver to Camargo Corrêa (or, in the case of an Initial Hedge Transfer, to the Hedging Counterparty that delivered the Proposed Sale Notice) no later than 9:00 a.m., New York City Time, on the Trading Day next succeeding the effective date of the Proposed Sale Notice (the “Exercise Deadline”), a written notice (the “Alcoa Exercise Notice”) confirming its election to purchase the Shares (or, in the case of an Initial Hedge Transfer, the Common Stock) described in the Proposed Sale Notice and identifying the purchaser or purchasers of such Shares (or, in the case of an Initial Hedge Transfer, the Common Stock). Alcoa’s notice shall be sent to Camargo Corrêa’s president and treasurer as set forth in Section 7.6 of this Agreement (or, in the case of an Initial Hedge Transfer, to the Hedging Counterparty delivering a Proposed Sale Notice at the address specified in such Proposed Sale Notice). Provided that Camargo Corrêa properly made (or, in the case of an Initial Hedge Transfer, caused the Hedging Counterparty to properly make) a Proposed Sale Notice in accordance with the provisions set forth herein, if Alcoa fails to deliver an Alcoa Exercise Notice to Camargo Corrêa (or, in the case of an Initial Hedge Transfer, to the Hedging Counterparty) by the Exercise Deadline (or if Alcoa notifies Camargo Corrêa, or, in the case of an Initial Hedge Transfer, the Hedging Counterparty, that it has elected not to purchase such Shares), then Alcoa will be deemed to have waived its right of first refusal with respect to the Transfer or Initial Hedge Transfer described in the Proposed Sale Notice and, subject to Section 4.2(g) of the Registration Rights Agreement, if the Transfer is proposed to be made under the Shelf Registration Statement, and subject to applicable law, the Camargo Group or its Affiliate shall be permitted to effect the Transfer (or, in the case of an Initial Hedge Transfer, permit consummation of the Initial Hedge Transfer) described in the Proposed Sale Notice by the end of the Trading Day on which the Exercise Deadline falls. Subject to the terms of this Agreement, delivery by Alcoa of an Alcoa Exercise Notice shall create a legally binding obligation on the part of Alcoa to purchase the Shares (or, in the case of an Initial Hedge Transfer, the Common Stock) and, subject to the provisions of Section 2.7, if applicable, a legally binding obligation on the part of the Camargo Group and/or its Affiliates to sell the Shares described in the Proposed Sale Notice on and subject to the terms set forth herein (or, in the case of an Initial Hedge Transfer, a legally binding obligation on the part of the Hedging Counterparty delivering a Proposed Sale Notice in connection with an Initial Hedge Transfer, to sell the Common Stock described in the Proposed Sale Notice on and subject to the terms set forth herein). Payment of the purchase price for, and delivery of the Shares purchased under this Section 2.4.2, shall be made on the third Trading Day after the Trade Date. Payment shall be made in U.S. Dollars upon confirmation of delivery of the Shares in the manner described below, by wire transfer of immediately available funds to the account specified in wire transfer instructions furnished to Alcoa by the president or treasurer of Camargo Corrêa (or, in the case of an Initial Hedge Transfer, by a duly authorized representative of the Hedging Counterparty that delivered the applicable Proposed Sale Notice). Delivery of the Shares (or in the case of an Initial Hedge Transfer, the Common Stock) shall be made as follows: (i) in the case of certificated Shares (or in the case of an Initial Hedge Transfer, certificated Common Stock), Camargo Corrêa (or in the case of an Initial Hedge Transfer, the Hedging Counterparty) shall physically deliver or cause to be delivered the Share certificates (or in the case of an Initial Hedge Transfer, the Common Stock certificates) representing the purchased Shares (or in the case of an Initial Hedge Transfer, the Common Stock), free and clear of all Liens, duly endorsed in blank for transfer, with signature(s) guaranteed, to Alcoa’s transfer agent, addressed to: Ms. Randi Galan, Equiserve, 525 Washington Boulevard, 9th Floor, Mail Suite, 4690, Jersey City, New Jersey, USA 07310; and (ii) in the case of Shares (or in the case of an Initial Hedge Transfer, Common Stock) held in 
 
8 

book-entry form, Camargo Corrêa (or in the case of an Initial Hedge Transfer, the Hedging Counterparty) shall duly issue or cause to be duly issued instructions to Equiserve to cause the purchased Shares (or in the case of an Initial Hedge Transfer, Common Stock) to be electronically transferred, free and clear of all Liens, in the direct registration system and posted to Alcoa’s or its designated Affiliate’s account at Equiserve. 
 
2.4.3 Exempt Transfers. Notwithstanding Section 2.4.2, the Camargo Group and its Affiliates will be entitled to make any of the following Transfers (collectively, the “Exempt Transfers”); provided that in the case of any Exempt Transfer (other than an Exempt Transfer pursuant to Section 2.4.3(b) or 2.4.3(c) (collectively, “Business Combination Transfers”) for which no notice is required) Camargo Corrêa shall give Alcoa written notice (an “Exempt Transfer Notice”) of a proposed Exempt Transfer at least five Trading Days prior to such Transfer (or in the case of any Exempt Transfer pursuant to Section 2.4.3(g), at least two Trading Days prior to such Transfer, except for Exempt Transfers in relation to the early termination of a Monetization Arrangement, in which case notice shall be given no later than one Trading Day following the occurrence of such Transfer). For the avoidance of doubt, none of the foregoing shall limit the applicability of the final sentence of Section 2.4.3(g). The effective time of an Exempt Transfer Notice shall be determined in accordance with the provisions of Section 2.4.2 relating to the effectiveness of a Proposed Sale Notice. The Exempt Transfers are as follows: 
 
2.4.3(a) Transfers to Camargo Corrêa Affiliates – any Transfer of Shares to Camargo Corrêa or to any Affiliate thereof who executes an agreement with the Transferring member of the Camargo Group confirming that any subsequent Transfer of such Shares by such Affiliate that occurs prior to the Restriction Termination Date will be subject to the restrictions and obligations set forth in this Agreement and the Registration Rights Agreement. The Camargo Group shall be responsible for any breaches by its Affiliates.

Not later than 6:00 p.m. New York City Time on the fifth Trading Day after the effective date of an Exempt Transfer Notice in respect of this Section 2.4.3(d), Alcoa shall deliver to the Camargo Group a written notice indicating whether or not it approves of the proposed Exempt Transfer and, if not, specifying with reasonable particularity, the reasons for its position. If such notice is not given by such time, Alcoa shall be deemed to have given the required approval. 
 
2.4.3(e) Alcoa-Agreed Restricted Transfers – any Transfer (other than, or in relation to, a Monetization Arrangement) of Shares to a Person (excluding the Camargo Group and its Affiliates) who executes an agreement with Alcoa prior to such Transfer confirming that any subsequent Transfer(s) by such Person or its Affiliates that occur prior to the Restriction Termination Date (including, without limitation, any subsequent Exempt Transfer other than (x) a Business Combination Transfer and (y) any Transfer by such Person to an Affiliate of such 
 
9 

Person who executes a similar agreement with Alcoa) will be subject to the Volume Limitation and the rights of first refusal of Alcoa described in this Section 2.4; provided that, prior to the Restriction Termination Date, the Camargo Group and its Affiliates shall not make more than two Transfers pursuant to this Section 2.4.3(e).

2.4.3(h) Pledges – any Transfer (other than, or in relation to, a Monetization Arrangement) of Shares to a bank or other financial institution as security for a loan or other financing or any Transfer of Shares to such bank or financial institution upon foreclosure, so long as such bank or financial institution executes an agreement with the Transferring member or Affiliate of the Camargo Group confirming that any subsequent Transfer by it or its Affiliates that occurs prior to the Restriction Termination Date (including, without limitation, any subsequent Exempt Transfer other than a Business Combination Transfer but excluding any Transfer by such bank or other financial institution to an Affiliate of such bank or financial institution that executes a similar agreement with the Transferring member or Affiliate of the Camargo Group) of such Shares will be subject to the Volume Limitation and to the rights of first refusal of Alcoa on terms as described in this Section 2.4. The Camargo Group shall: (i) ensure that such contract is in accordance with the applicable provisions of this Agreement, 
 
10 

(ii) ensure that such contract provides that Alcoa is an express beneficiary thereof and is entitled to enforce the provisions thereof, (iii) provide true and correct copies of the contract to Alcoa before the execution thereof and at least two Trading Days prior to the Transfer, and (iv) provide true and correct copies of such executed contract to Alcoa prior to the Transfer. 
 
2.4.4 Use of Shelf Registration Statement by Transferees; Persons Eligible to be Permitted Sellers. Other than assignments to Affiliates of the Camargo Group, the Camargo Group and its Affiliates agree that the rights and obligations under the Registration Rights Agreement may only be assigned to a Transferee acquiring Shares in a Transfer if such Transfer cannot reasonably be accomplished under the Shelf Registration Statement or under Rule 144 of the Securities Act by the proposed closing date of the proposed Transfer. Furthermore, the parties agree that the number of Transferees who may be assignees of the Registration Rights Agreement and thus eligible to be Permitted Sellers (as such term is defined in the Registration Rights Agreement) is subject to the following limitations: 
 
(a) no more than two (2) Transferees pursuant to each of Sections 2.4.3(d), 2.4.3(e), 2.4.3(f), 2.4.3(g), and 2.4.3(h); and 
 
(b) no more than eight (8) Transferees (other than the Camargo Group and its Affiliates) in the aggregate at any time. 
 
Furthermore, each such Transferee (other than the Camargo Group and its Affiliates) shall be eligible to reassign in whole its rights and obligations under the Registration Rights Agreement only once to one subsequent Transferee of the Shares (who shall have no further assignment rights) if such subsequent Transfer cannot reasonably be accomplished under the Shelf Registration Statement or under Rule 144 of the Securities Act by the proposed closing date of the proposed Transfer and provided that under all circumstances the total number of Transferees (other than the Camargo Group and its Affiliates) eligible at any given time to be Permitted Sellers under the Registration Rights Agreements is subject to the limitation set forth in (b) above. The Camargo Group and its Affiliates shall: (i) give prior written notice to Alcoa in accordance with Section 7.6 of any assignment by it of the rights and obligations of the Registration Rights Agreement hereunder (which notice may be included as part of the Proposed Sale Notice); (ii) ensure that the assignee agrees to all restrictions and obligations imposed under the Registration Rights Agreement; (iii) ensure that the assignee agrees to the provisions of this Section 2.4.4, including those relating to any reassignment by it, and agrees to give prior written notice to Alcoa in accordance with the provisions of Section 7.6 of any such reassignment. Any such assignment shall not be effective unless the proposed Transferee executes and delivers a written instrument reasonably satisfactory to Alcoa whereby such proposed Transferee agrees to be bound by the restrictions and obligations under the Registration Rights Agreement and the limitations on assignment of the Registration Rights Agreement contained in this Section 2.4.4. 
 
2.4.5 Restrictions on Transferees. Upon consummation of any Transfer of Shares prior to the Restriction Termination Date, the Person to whom the Transfer is made (the “Transferee”) will be subject to, in addition to any restrictions or obligations imposed under the Registration Rights Agreement, if applicable to such Transferee, and the Securities Act, the following restrictions on the subsequent Transfer of such Shares:

2.5 Certain Alcoa Alumínio and ALAHC Matters. The parties agree that the total amount of the Camargo Group’s dividend distributions from Alcoa Alumínio and ALAHC relating to 2002 and a portion of 2003 will be R$ 31,688,230 from Alcoa Alumínio and U.S.$1,146,068 from ALAHC. The remittance of the dividend distributions: (a) from Alcoa Alumínio shall be made prior to the transfer to the Alcoa Group of the BACEN certificates of registration as set forth in Section 3.3.3 of this Agreement; and (b) from ALAHC shall be made prior to Closing. Following the Closing, the Camargo Group shall not be entitled to receive any additional dividend distributions from Alcoa Alumínio and ALAHC. During the Earn-Out Period after the Closing, the Alcoa Group agrees that the Camargo Group may have one observer attend meetings of the board of directors (i.e. the Conselho de Administração) of Alcoa Alumínio for so long as such body is maintained and retains its current scope of authority. The Alcoa Group reserves the right to change or eliminate such body; provided that, in the event that the board of directors is replaced by a consulting board or other body having similar functions, the Camargo Group will be entitled to have an observer attend the meetings of such board or other body. Unless the parties agree otherwise, the Camargo Group’s observer shall continue to be provided with, with respect to the period covered by the Earn-Out Period: (i) the Alcoa Latin America Financial Report (“Blue Book”) prepared and circulated monthly; and (ii) a reconciliation between financial statements included in each December edition of the Blue Book with the numbers included in the calculation of the EBITDA for the year (whether or not provided to the board of directors, consulting board or other similar body). If the board of directors is eliminated without being replaced by a consulting board or other body having similar functions, the Camargo Group’s observer shall be provided with, with respect to the period covered by the Earn-Out Period, and in addition to the documents specified in the previous sentence: (i) reports prepared by each business unit for review and discussion with the Alcoa Inc. senior executives as part of the quarterly review process; and (ii) access on a bi-monthly basis to the Alcoa Alumínio chief financial officer. In any event, the observer shall be a non-voting observer and shall not participate in management or in the formulation, determination, or direction of basic business decisions, but the observer shall receive as to content and timing the same information and material relating to the business of Alcoa Alumínio as is provided to the other members of such board or body. The information provided to the Camargo Group’s observer shall be subject to the confidentiality provisions of Section 7.9. The Camargo Group’s initial observer is Francisco Caprino Neto. Further, the Camargo Group represents that it has no present intention of participating in the formulation, determination or direction of the basic business decisions of Alcoa and does not intend to nominate a candidate for Alcoa’s board of directors, propose corporate action requiring shareholder approval, or solicit proxies. Notwithstanding the above, the Camargo Group may vote its shares in Alcoa. 
 
2.6 Adjustments to Number of Shares. If, during the period between Closing and the Restriction Termination Date, there is a pro-rata change in the number of outstanding shares of Common Stock as a result of a stock split, reverse stock split, or similar Alcoa corporate action that results in a pro rata adjustment of the market price of the shares of Common Stock, then Alcoa will adjust accordingly the number of shares and per share prices used in the calculations 
 
13 

in Exhibit C (e.g., the Threshold Share Price) and the number of Shares set forth in Section 2.7.3(ii). If such an event occurs during the period between the date of this Agreement and Closing, then in addition to the adjustments described in the foregoing sentence, the parties shall also adjust the number of Shares accordingly and shall amend this Agreement before Closing to reflect the adjusted amounts. Notwithstanding anything in this Agreement, for the avoidance of doubt the parties hereby confirm that the number of Shares delivered hereunder and the Earn-Out Payments calculations set forth in Exhibit C shall not be adjusted to reflect changes in the value of Alcoa Alumínio Stock, the ALAHC Stock or the Common Stock after the date hereof, whether due to (i) any change or effect that is materially adverse to business, operations, property, assets, liabilities or the financial or operational condition of Alcoa Alumínio, ALAHC or Alcoa, (ii) changes or conditions affecting the industries in which Alcoa Alumínio, ALAHC or Alcoa operate (including metals or aluminum pricing), (iii) changes in economic, regulatory or political conditions generally (including acts of terrorism or war) or (iv) otherwise. 
 
2.7 Special Option During First Year After the Closing Date. Subject to the limitations set forth in Section 2.7.3 below, if Camargo Corrêa delivers, at any time before the first anniversary of the Closing a Shelf Notice of Sale pursuant to Section 4.2(g) of the Registration Rights Agreement and corresponding Proposed Sale Notice pursuant to Section 2.4.2 of this Agreement and a Delay Period is in effect with respect to the Transfer described in such notices, Alcoa and the Camargo Group shall comply with procedure I below (“Procedure I”), unless Alcoa includes a statement in its Delay Period Notice given pursuant to Section 4.2(g) of the Registration Rights Agreement that procedure II below (“Procedure II”) shall apply in respect of such Delay Period instead of Procedure I. 
 
2.7.1 Procedure I. 
 
(i) Disclosure of Confidential Information. Alcoa shall provide to Camargo Corrêa by the Delay Period Notice Deadline a description in reasonable detail of the non-public information that is the reason for the Delay Period (the “Confidential Information”). The receipt of the Confidential Information by Camargo Corrêa shall be subject to the confidentiality agreement set forth in Section 7.9 of this Agreement. In addition, and without limiting the foregoing, each member of the Camargo Group agrees during the Delay Period to maintain the Confidential Information in strict confidence and not to disclose it to any third party or trade in any Alcoa securities. 
 
(ii) Rescission Right. Upon receipt of the Confidential Information in accordance with the immediately preceding clause (i), Camargo Corrêa shall have a right to rescind the previously delivered Shelf Notice of Sale and corresponding Proposed Sale Notice by so notifying Alcoa in writing no later than 9:00 a.m., New York City Time, on the Trading Day next succeeding the Delay Period Notice Deadline (the “Procedure I Rescission Deadline”). If Camargo Corrêa rescinds its Shelf Notice of Sale and corresponding Proposed Sale Notice, then the Camargo Group and its Affiliates may not deliver additional Shelf Notices of Sale or corresponding Proposed Sale Notices until such Delay Period is no longer in effect. If Camargo Corrêa does not rescind its Shelf Notice of Sale, then it may deliver additional notice(s) during such Delay Period but the Camargo Group shall not have rescission rights with respect to such additional notice(s) unless there is an additional disclosure of new or different Confidential Information pursuant to such additional notice, in which case the provisions of this subsection (ii) shall apply. 
 
(iii) Purchase of Shares and Settlement Procedures. Unless the Shelf Notice of Sale and corresponding Proposed Sale Notice are rescinded by Camargo Corrêa by the 
 
14 

Procedure I Rescission Deadline, the Camargo Group shall be deemed to have waived its rescission right with respect to such Shelf Notice of Sale and corresponding Proposed Sale Notice and Alcoa shall be obligated to purchase the Shares indicated in such Shelf Notice of Sale and corresponding Proposed Sale Notice, subject to the limitations set forth in Section 2.7.3 below, at the Average Price for the applicable Trading Day as determined in accordance with Section 2.4.2 of this Agreement. The settlement procedures applicable to the purchase of such Shares shall be as provided in Section 2.4.2 of this Agreement. 
 
2.7.2 Procedure II. 
 
(i) Deferred Disclosure of Confidential Information. Alcoa may defer disclosing the Confidential Information to Camargo Corrêa beyond the Delay Period Notice Deadline until (x) the date that such Confidential Information is publicly disclosed (the “Delay Period Termination Date”) or (y) such other date during the Delay Period as Alcoa is able or deems it appropriate to disclose such information to Camargo Corrêa. If Alcoa discloses the Confidential Information to Camargo Corrêa before the information is publicly disclosed, Camargo Corrêa’s receipt of such Confidential Information shall be subject to the confidentiality agreement set forth in Section 7.9 of this Agreement. In addition, without limiting the foregoing, each member of the Camargo Group agrees to maintain the Confidential Information in strict confidence and not to disclose it to any third party or trade in any Alcoa securities. 
 
(ii) Rescission Right. Once the Confidential Information is disclosed to Camargo Corrêa in the manner described in the immediately preceding clause (i), Camargo Corrêa shall have a right to rescind all (but not less than all) Shelf Notices of Sale and corresponding Proposed Sale Notices theretofore delivered by it during such Delay Period by notifying Alcoa in writing no later than 9:00 a.m., New York City Time, on the earlier of (x) the Trading Day next succeeding the Delay Period Termination Date or (y) the Trading Day next succeeding Camargo Corrêa’s receipt of the Confidential Information (the “Procedure II Rescission Deadline”). 
 
(iii) Purchase of Shares and Settlement Procedures. Unless all such Shelf Notices of Sale and corresponding Proposed Sale Notices are rescinded by Camargo Corrêa by the applicable Procedure II Rescission Deadline as provided in the immediately preceding clause (ii), the Camargo Group shall be deemed to have waived its rescission right with respect to all such Shelf Notices of Sale and corresponding Proposed Sale Notices and Alcoa shall be obligated to do the following after the Delay Period Termination Date, as Alcoa elects for each Shelf Notice of Sale and corresponding Proposed Sale Notice in its sole discretion: (x) to purchase all of the Shares indicated in each such Shelf Notice of Sale and corresponding Proposed Sale Notice, subject to the limitations set forth in Section 2.7.3 below, at the Average Price for the applicable Trading Day as determined in accordance with Section 2.4.2 of this Agreement, or (y) subject to compliance with applicable law, to arrange for the purchase of all of the Shares indicated in each Shelf Notice of Sale and corresponding Proposed Sale Notice by a third party on such terms as the parties shall agree, provided that Alcoa shall pay Camargo Corrêa the difference, if any, between the price obtained for the Shares under such arrangement and the price of such Shares as determined by reference to the applicable Average Price per Share calculated under the formula set forth in the immediately preceding sub-clause (x). If Alcoa purchases the Shares under sub-clause (x), the settlement procedures applicable to the purchase of such Shares shall be as provided in Section 2.4.2 of this Agreement, except that the payment for and delivery of the Shares shall be made on or no later than the third Trading Day after the Delay Period Termination Date. If the Shares are purchased under sub-clause (y), the settlement procedures shall be as agreed by the parties but in no event shall payment for and delivery of the Shares be made later than on the tenth Trading Day after the Delay Period 
 
15 

Termination Date. For clarification, if more than one Shelf Notice of Sale and corresponding Proposed Sale Notice are outstanding, Alcoa may elect subclause (x) with respect to some Shelf Notices of Sale and corresponding Proposed Sale Notices and subclause (y) with respect to others. 
 
2.7.3 Limitations on Special Option. Notwithstanding anything to the contrary contained in this Agreement, the parties agree that: 
 
(i) Section 2.7 is applicable only with respect to Shelf Notices of Sale (and corresponding Proposed Sale Notices) that become effective during the first year after the Closing Date, and Alcoa shall have no obligation to purchase (or to cause the purchase of) any Shares covered by such notices that become effective on or after the first anniversary date of the Closing Date (the “Special Option Expiration Date”). 
 
(ii) Alcoa shall not be required to purchase (or to cause the purchase of) more than 900,000 Shares pursuant to any single Shelf Notice of Sale and corresponding Proposed Sale Notice nor more than 8,886,770 Shares in the aggregate pursuant to all Shelf Notices of Sale and corresponding Proposed Sale Notices that become effective before the Special Option Expiration Date. 
 
(iii) The rights and obligations of the Camargo Group under this Section 2.7 are personal to the Camargo Group and its Affiliates and may not be assigned or otherwise transferred to any other Person. For the avoidance of doubt, no Permitted Seller (as defined in the Registration Rights Agreement) or other Person who is not an Affiliate of the Camargo Group shall have any right or benefit under such subsections 2.7.1 or 2.7.2. 
 
2.8 Counsel Opinions for Transfers Other Than Under the Shelf Registration. Until the second anniversary of the Closing Date, prior to making any Transfer of Shares to any Person, other than a Transfer registered under the effective Shelf Registration Statement, Camargo Corrêa will give written notice to Alcoa of the intention by a member or Affiliate of the Camargo Group to effect such Transfer. Each such notice shall describe the manner and circumstances of the proposed Transfer. Unless the proposed Transfer is a Business Combination Transfer as set forth in Sections 2.4.3(b) or 2.4.3(c), if within 5 Trading Days (or 2 Trading Days in the case of Transfers pursuant to Section 2.4.3(g)) after receipt by Alcoa of such notice, Alcoa requests an opinion of counsel for such member or Affiliate of the Camargo Group that the proposed Transfer may be effected without registration of the Transfer under the Securities Act (such counsel opinion to be reasonably satisfactory to legal counsel for Alcoa), then Alcoa shall not be required to cause its share transfer agent to record such Transfer, and the Camargo Group and its Affiliates shall not be entitled to effect such Transfer, unless and until Alcoa receives such a counsel opinion reasonably satisfactory to Alcoa.

The foregoing provisions shall not operate as a release of any claims or liabilities arising out of a breach by a party hereto of any of its covenants or agreements or representations or warranties set forth in this Agreement.

7.9 Confidentiality. Each member of the Camargo Group will hold, and will ensure that its officers, directors, employees, accountants, counsel, consultants, advisors and agents hold, in confidence and not disclose to any third party, unless compelled to disclose by judicial or administrative process or by other requirements of law, all financial, technical or other confidential information furnished to the Camargo Group by the Alcoa Group in connection with the transactions contemplated by this Agreement, except to the extent that such information can be shown to have been (i) previously known on a nonconfidential basis by a member of the Camargo Group, (ii) in the public domain through no fault of any member of the Camargo Group or (iii) later lawfully acquired by a member of the Camargo Group from sources other than the Alcoa Group who had no duty to hold it as confidential. The Camargo Group may disclose such information to its officers, directors, employees, accountants, counsel, consultants, advisors and agents who have a need to know such information in connection with the transactions contemplated by this Agreement so long as such persons are informed by the Camargo Group of the confidential nature of such information and are obligated by the Camargo Group to treat such information confidentially and in any arbitral or judicial proceeding pursuant to Section 7.17. Notwithstanding the foregoing, the Camargo Group may disclose the tax treatment and tax structure of the transactions contemplated by this Agreement (including any materials, opinions or analyses relating to such tax treatment or tax structure, but without disclosure of identifying information or, except to the extent relating to such tax structure or tax treatment, any nonpublic commercial or financial information). Moreover, notwithstanding any other provision of this Agreement, there shall be no limitation on the Camargo Group’s ability to consult any tax adviser, whether or not independent from Camargo Group or its Affiliates, regarding the tax treatment or tax structure of the transactions contemplated by this Agreement. The Camargo Group shall be responsible for any failure to treat such information confidentially by such Persons and their respective officers, directors, employees, accountants, counsel, consultants, advisors and agents. 
 
7.10 Assignment. Neither this Agreement nor any of the rights or obligations hereunder may be assigned by the Alcoa Group or the Camargo Group without the prior written consent of the other, which shall not be unreasonably withheld; provided, however, that the Camargo Group may assign the right to receive any Earn-Out Payment(s) and any Guaranteed Minimum Payment to its Affiliates provided the Camargo Group remains liable for its obligations hereunder. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective legal representatives, successors, heirs and assigns, and no other person has any right, benefit or obligation hereunder. 
 
7.11 Waiver. The waiver by any party of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any subsequent breach.

7.13 Counterparts. This Agreement may be executed in two or more counterparts in English, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 
 
7.14 Severability. If any term, covenant, condition or provision of this Agreement or the application thereof to any circumstance shall be invalid or unenforceable to any extent, the 
 
29 

remaining terms, covenants, conditions and provisions of this Agreement shall not be affected thereby and each remaining term, covenant, condition or provision of this Agreement shall be enforceable to the fullest extent permitted by law. 
 
7.15 No Drafting Presumption.

7.16 Choice of Law. This Agreement shall be construed, interpreted and the rights of the parties interpreted in accordance with the laws of the State of New York, excluding those related to choice or conflicts of law. 
 
7.17 Dispute Resolution. In an effort to resolve informally and amicably any dispute or controversy which might arise between the parties with respect to this Agreement, without first resorting to any third party or tribunal for resolution, the parties shall first endeavor to resolve the matter through direct discussions and negotiations. If the matter cannot be settled, it shall be referred by each party to a responsible officer of each Alcoa and Camargo Corrêa. If the two officers are unable to resolve the matter within 30 days of its referral, the matter will be referred to the Chief Executive Officers of Alcoa and Camargo Corrêa. If settlement is not thereafter reached through their efforts within an additional 30 days, or such longer time period as they may agree, then either party may initiate arbitration proceedings to resolve the matter. Any such dispute, controversy or claim in connection with this Agreement, including its validity, interpretation, application, scope, enforceability, performance, breach and termination, shall be resolved exclusively and finally by arbitration, to the exclusion of the courts. Notice of arbitration shall be deemed proper if made in accordance with Section 7.6 of this Agreement. If the parties fail to agree in writing on the place where the arbitration is to be conducted, such arbitration shall be held in New York, New York, United States of America. Arbitration shall be conducted in English, pursuant to International Chamber of Commerce (“ICC”) Arbitration Rules in force at the time of the arbitration, by a panel of three arbitrators who are fluent in the English language and who are skilled in the legal and business aspects of the subject matter of this Agreement. The arbitrators shall be appointed in accordance with ICC Rules. Any monetary award made pursuant to such arbitration shall be calculated and paid exclusively in Dollars. Judgment upon the award rendered may be entered in any court having jurisdiction, or an application may be made to any court for a judicial acceptance of the award and an order of enforcement, as the case may be. Each of the parties hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any Federal court of the United States of America sitting in New York City and any appellate court from thereof for recognition or enforcement of any such judgment. Each party hereby irrevocably and unconditionally waives any objection (including any defense of inconvenient forum) which it may now or hereafter have to the laying of such venue, and each party irrevocably consents to service of process in the manner provided for notices in Section 7.6. 
 
7.18 Entire Agreement and Modifications. This Agreement, together with the Exhibits hereto (including the Registration Rights Agreement), constitute the entire agreement between the parties with respect to the subject matter hereof and supersede all prior agreements (including the Agreement in Principle), understandings, negotiations and discussions, whether oral or written, of the parties. No supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the party to be bound thereby.

(CPF)] (the “Grantee”), to whom it grants special powers in order to, [jointly or separately,] on behalf and in the name of Grantor, (i) transfer to Alcoa Luxembourg, S.à.r.l., a private limited liability company organized and existing under the laws of Luxembourg, enrolled with the Brazilian tax authorities (CNPJ/MF) under number 05.731.008/0001-41 (“AL”),                      nominative common shares, with all their attendant rights, which Grantor holds in the corporate capital of the Brazilian corporation Alcoa Alumínio S.A. (“Alcoa Alumínio”) and which are part of the group of shares of common stock of Alcoa Alumínio, defined as the “Alcoa Alumínio Stock” in the Principal Agreement by and among Alcoa Inc., Alcoa Luxembourg S.à.r.l., Camargo Corrêa S.A., Allpar Limited, and Trelawney Inc. dated July     , 2003 (the “Agreement”), to be exchanged in accordance with the terms and conditions of the Agreement; (ii) sign the statement of transfer of the shares listed in item (i) above in the Alcoa Alumínio’s Book of Transfer of Nominative Shares, showing Grantor as the assignor and AL as the assignee of such shares thereby transferred, in compliance with Article 31, § 1, of the Brazilian Law of Corporations.

Exhibit C 
 
EARN-OUT PAYMENTS AND GUARANTEED MINIMUM PAYMENT 
 
A. EARN-OUT PAYMENTS 
 
This is Exhibit C to the Principal Agreement dated July 25, 2003 (the “Agreement”) among Alcoa Inc., Alcoa Luxembourg S.à.r.l., Camargo Corrêa S.A., ALLPAR Limited and Trelawney Inc. Capitalized terms used and not defined herein have the respective meanings assigned to them in the Agreement. 
 
The Camargo Group will be entitled to receive Earn-Out Payments (defined below), if the conditions set forth herein are met. Earn-Out Payments will be calculated on the basis of growth in Alcoa Alumínio’s and ALAHC’s (the “Subsidiaries”) five-year average annual EBITDA (defined below) from an agreed base EBITDA of U.S.$182 million. 
 
The right to receive Earn-Out Payments and the Guaranteed Minimum Payment is not conditioned or contingent on the Camargo Group retaining an interest in the Shares. 
 
Each Earn-Out Payment will be made in cash by Alcoa (as a U.S. Person) or by its designated Affiliate (provided that such Affiliate is a U.S. Person) to Trelawney and Allpar, in the same proportion as they receive Shares of Alcoa Common Stock on the Closing Date (i.e. 42% to Trelawney and 58% to Allpar). However, notwithstanding that an Earn-Out Payment, if the conditions set forth herein are met, is made in cash, any subsequent calculation of Capital Gain Offset (defined below) or notional dividends per share (see the Guaranteed Minimum Payment section below) will be made as if such Earn-Out Payment had been made in additional shares of Alcoa Common Stock (see below for calculations). The Earn-Out Payment period (the “Earn-Out Period”) will be five fiscal years beginning with the fiscal year ended December 31, 2003 and will be based on the calculation periods described herein. Each Earn-Out Payment will be made, if the conditions set forth herein are met, annually by June 30 of the year subsequent to the year in respect of which the payment is made, beginning June 30, 2004. 
 
Based upon the parties’ understanding of current U.S. tax law, each Earn-Out Payment made by Alcoa to Trelawney and Allpar is not subject to deduction for any tax or withholding. In the event that U.S. tax law changes, the parties agree that taxes or withholdings will be properly withheld from future payments if required by applicable U.S. tax law. Additionally, for any Earn-Out Payment made by a U.S. Person, the parties agree to treat the amount of interest imputed with respect to such payment pursuant to Section 483 of the Internal Revenue Code of 1986, as amended, (“IRC”) as “portfolio interest” within the meaning of Section 871(h) of the IRC. In this regard, it is agreed that in no event will the right to receive Earn-Out Payment(s) be assigned or transferred to a U.S. Person. It is further agreed that all payments which may contain imputed interest are payable outside the U.S. Any U.S. Person who holds this obligation for Earn-Out Payment(s) will be subject to limitations provided in Section 165(j) and 1287(a) of the Internal Revenue Code of 1986. In the event that the Alcoa Group or its Affiliates are assessed for the withholding taxes by the tax authorities, and all administrative appeals are exhausted in good faith (provided that the Alcoa Group shall not be obligated to pursue litigation), the Camargo Group agrees to reimburse the Alcoa Group and its Affiliates for any past withholding taxes paid to the U.S. tax authorities by the Alcoa Group or its Affiliates. 
 
36 

In establishing the value of U.S. $410 million as forth in Section 2.1 of the Agreement, the parties have agreed that the Subsidiaries’ five-year average annual EBITDA for the period January 1, 1998 through December 31, 2002 is U.S.$182 million (the “Base EBITDA”) and is based on the following annual EBITDA figures, which shall be used as necessary in the subsequent annual five-year average EBITDA calculations described below: U.S. $134 million for the period January 1, 1998 through December 31, 1998; U.S.$155 million for the period January 1, 1999 through December 31, 1999; U.S.$233 million for the period January 1, 2000 through December 31, 2000; U.S.$206 million for the period January 1, 2001 through December 31, 2001; and U.S.$182 million for the period January 1, 2002 through December 31, 2002. The same methodology and definition (as set forth below) used in determining EBITDA for Base EBITDA purposes will be used in determining EBITDA for periods after January 1, 2003, provided that: 
 
1. The results of any new business that is acquired or established by the Subsidiaries on or after January 1, 2003 and the results of any major investment made by the Subsidiaries on or after January 1, 2003 will be disregarded in determining EBITDA. For example, if either of the Subsidiaries makes any material acquisition or investment after January 1, 2003 and before the end of the Earn-Out Period, neither the financial results (including, without limitation, the revenues, liabilities and expenses of the acquired business) nor any debt or other liability incurred to finance such acquisition or investment shall be included in any annual EBITDA calculation. Examples of “new businesses” or “major investments” for purposes of this paragraph include: (a) entering a new line of business; and (b) material expansions of capacity (e.g., an additional line at a smelter, investing in cold-finish rod and bar equipment and facilities, significant investments in hydroelectric facilities, etc.). For clarification, the 27.23% investment in the hydroelectric facility at Machadinho and the 31.57% investment in the hydroelectric facility at Barra Grande will be included in the calculations of EBITDA. 
 
2. If any business that had been part of the Base EBITDA calculation is sold on or after January 1, 2003, the gain or loss related to the sale of such business will not be taken into consideration in the annual EBITDA calculation, but the Alcoa Group will pay to Trelawney and Allpar (42% to Trelawney and 58% to Allpar), in cash in the currency received by the Subsidiaries in such sale, an amount equal to 40.9% (representing the Camargo Group’s ownership interest in the Subsidiaries prior to the Closing) of the excess by which the sales price received for such business exceeded 6.5 times (the agreed earnings multiple) the EBITDA of such business for the average of the last five fiscal years prior to such sale, payable within 30 days after the later of the Closing Date and the date of such sale. 
 
As used herein, EBITDA is defined and calculated as follows: 
 
 	  	 	  	1998
	  	1999
	  	2000
	  	2001
	  	2002
	
 	  	Total revenue	  	1077.8	  	891.1	  	1057.5	  	929.8	  	825.1	
Minus	  	Total cost of goods sold	  	972.5	  	744.5	  	825.6	  	726.9	  	635.8	
Minus	  	General administrative and selling expense	  	68.7	  	64.5	  	66.3	  	55.2	  	51.7	
Minus	  	Research and development expense	  	1.2	  	1.9	  	1.9	  	3.9	  	3.3	
 	  	 	  		  		  		  		  		
Resulting in the subtotal:	  	Net margin	  	35.4	  	80.3	  	163.7	  	143.9	  	134.3	
Plus (for Equity
income) or	  	 	  	 	  	 	  	 	  	 	  	 	
 
37 

Minus (for Equity loss)	  	Equity income/(Equity loss)	  	6.3	  	(4.8	)	 	3.1	  	2.0	  	1.3	
Plus	  	Depreciation (including amortization)	  	92.3	  	79.8	 	 	66.6	  	60.0	  	46.7	
 	  	 	  		  			 		  		  		
Resulting in total:	  	EBITDA	  	134.0	  	155.3	 	 	233.4	  	205.9	  	182.4	
 
The EBITDA calculation amounts will be derived from U.S. Dollar financial information prepared from the books and records of Alcoa Alumínio and ALAHC. Such information will be prepared in accordance with Alcoa’s accounting policies and procedures applied on a consistent basis, which policies and procedures shall comply in all material respects with the accounting policies and procedures used in determining Base EBITDA. For clarification, results of operations held for sale but not yet sold (discontinued operations) are part of the EBITDA calculations, but items classified in the non-operating income/expense categories of Alcoa’s chart of accounts (e.g., other income/expense, foreign exchange and derivative gains/losses, special items and gains/losses on investments) other than equity income (as specified in the chart above) are not part of the EBITDA calculations. All calculations shall be in U.S. Dollars. Annual reviews of calculations as they relate to periods after January 1, 2003 shall be as provided in Section 7.8 of the Agreement. 
 
To determine the notional number of shares that represent an Earn-Out Payment for these calculations (the Notional Earn-Out Shares, as defined below), the amount of the Earn-Out Payment will be divided by the average closing price of Alcoa Common Stock on the New York Stock Exchange (as reported by Bloomberg Financial Markets, or, if not reported thereby, by another authoritative source as may be agreed by the parties in writing) for the three calendar month period from March 1 through May 31 immediately preceding such Earn-Out Payment. Specifically, as used herein: 
 
Year 1 Average Closing Price	  	means the average closing price of Alcoa common stock on the New York Stock Exchange for the three calendar month period from March 1, 2004 through May 31, 2004.	
		
Year 2 Average Closing Price	  	means the average closing price of Alcoa common stock on the New York Stock Exchange for the three calendar month period from March 1, 2005 through May 31, 2005.	
		
Year 3 Average Closing Price	  	means the average closing price of Alcoa common stock on the New York Stock Exchange for the three calendar month period from March 1, 2006 through May 31, 2006.	
		
Year 4 Average Closing Price	  	means the average closing price of Alcoa common stock on the New York Stock Exchange for the three calendar month period from March 1, 2007 through May 31, 2007.	
		
Year 5 Average Closing Price	  	means the average closing price of Alcoa common stock on the New York Stock Exchange for the three calendar month period from March 1, 2008 through May 31, 2008.	
		
Year 1 Notional Earn-Out Shares	  	means the number of shares calculated by dividing the Year 1 Earn-Out Payment (defined below) by the greater of: the Year 1 Average Closing Price; or $19.00.	
		
Year 2 Notional Earn-Out Shares	  	means the number of shares calculated by dividing the Year 2 Earn-Out Payment (defined below) by the greater of: the Year 2 Average Closing Price; or $19.00.	
		
Year 3 Notional Earn-Out Shares	  	means the number of shares calculated by dividing the Year 3 Earn-Out Payment (defined below) by the greater of : the Year 3 Average Closing Price; or $19.00.	
 
38 

Year 4 Notional Earn-Out Shares	  	means the number of shares calculated by dividing the Year 4 Earn-Out Payment (defined below) by the greater of: the Year 4 Average Closing Price; or $19.00.	
 
1. Annual Five-Year Average EBITDA Calculation. 
 
At the end of each fiscal year, the Alcoa Group will calculate the Subsidiaries’ average annual EBITDA for the five years then ended. This average will be compared to the Base EBITDA of U.S.$182 million. 
 
2. Earn-Out Opportunity 
 
If the difference between the latest average annual five-year EBITDA amount and the Base EBITDA of U.S.$182 million is a positive amount, such difference will be multiplied by 6.5 (the agreed earnings multiple) and the resulting product will be further multiplied by 40.9% (representing the Camargo Group’s ownership interest in the Subsidiaries prior to the Closing) to obtain the Earn-Out Opportunity. The Earn-Out Opportunity for each year is capped at U.S.$235 million. Any amount over U.S.$235 million is disregarded for purposes of any further calculation. As used herein: 
 
Year 1 Earn-Out Opportunity	  	means the calculation described above based on the average annual five-year EBITDA amount for the period January 1, 1999 through December 31, 2003.

A Share Price Event is deemed to have occurred whenever the simple arithmetic average of each day’s closing price per share of Alcoa Common Stock on the New York Stock Exchange (as reported by Bloomberg Financial Markets, or, if not reported thereby, by another authoritative source as may be agreed by the parties in writing) determined for any period of 30 consecutive Trading Days during the five-year period from May 5, 2003 through May 4, 2008 exceeds U.S.$32 per share (the Threshold Share Price). For purposes of the calculation in the previous sentence, from the Closing Date until the second anniversary thereof, if: (a) Camargo Corrêa delivers a Proposed Sale Notice to Alcoa pursuant to Section 2.4.2 of the Agreement; (b) the Camargo Group and its Affiliates are prevented from selling the Shares described in such Proposed Sale Notice under the Shelf Registration Statement because the Shelf Registration Statement is not effective or a Delay Period is in effect; (c) such Shares cannot, based upon written advice of counsel to Camargo Corrêa reasonably acceptable to Alcoa, be sold by the Camargo Group and its Affiliates under Rule 144 without violating the confidentiality agreement set forth in Section 7.9 of the Agreement or in Section 4.2(g)(3) of the Registration Rights Agreement; (d) Camargo Corrêa does not rescind such Proposed Sale Notice pursuant to Section 2.7 of the Agreement; and (e) no sale of such Shares to Alcoa or its Affiliates (or to a third party arranged by Alcoa after public disclosure of Confidential Information) is consummated under Section 2.4.2 or 2.7 of the Agreement, then the Trading Day next succeeding the Trading Day on which such Proposed Sale Notice was effective shall be excluded from the period of 30 consecutive Trading Days described in the preceding sentence. For the avoidance of doubt, the period of 30 consecutive Trading Days for the purposes of such calculation shall include Trading Days (other than excluded Trading Days) before and after the excluded Trading Day. Alcoa will give written notice to the Camargo Group of its determination that a Share Price Event has occurred. 
 
If applicable, the number of shares and per share prices used in the above calculations (e.g., the Threshold Share Price) will be adjusted in accordance with Section 2.6 of the Agreement. For illustrative purposes only, examples of the above calculations are attached hereto as Exhibit C-1.

The   
 
4 

registration of the Shares so effected by Alcoa pursuant to this Section is referred to herein as the “Shelf Registration”. 
 
4.2 Registration Procedures. With respect to the Shelf Registration under this Article IV, Alcoa will: 
 
(a) before filing the Shelf Registration Statement or prospectus or any amendment or supplement, furnish to and afford the Camargo Group and any Permitted Seller and the managing underwriters, if any have been identified, a reasonable opportunity to review copies of all such documents (including copies of any documents to be incorporated by reference therein and all exhibits thereto) proposed to be filed (in each case at least three business days prior to such filing or such later date as is reasonable under the circumstances), and Alcoa shall not file the Shelf Registration Statement or prospectus or any amendments or supplements thereto if the Permitted Seller, its counsel, or the managing underwriters, shall reasonably object on a timely basis to such filing by reason of such filing containing incorrect or misleading information pertaining to the Permitted Seller or the managing underwriters; and furnish to Camargo Corrêa (on behalf of each member or Affiliate of the Camargo Group that is a Holder of Shares) and each Shelf Registration Beneficiary such number of copies of the Shelf Registration Statement, each amendment and supplement thereto, the prospectus included in such Shelf Registration Statement (including each preliminary prospectus, all exhibits thereto and documents incorporated by reference therein) and such other documents as such Shelf Registration Beneficiary may reasonably request during the Effectiveness Period in order to facilitate the disposition of the Shares owned by the Shelf Registration Beneficiary; 
 
(b) use its best efforts during the Effectiveness Period to register or qualify all Shares included in the Shelf Registration under such other securities or blue sky laws of such jurisdictions in the U.S. as any selling Shelf Registration Beneficiary reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such Shelf Registration Beneficiary to consummate the disposition in such jurisdictions of such Shares to be sold by such Shelf Registration Beneficiary (provided that Alcoa will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph, (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction); 
 
(c) notify each Shelf Registration Beneficiary selling Shares in such offering, at any time during the Effectiveness Period when a prospectus relating thereto is required to be delivered under the Securities Act, (i) upon discovery that, or upon the discovery of the happening of any event as a result of which, the prospectus included in the Shelf Registration contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made, and subject to Section 4.2(g) below, at the request of such Shelf Registration Beneficiary, Alcoa will as promptly as practically possible prepare and file with the SEC and, at the request of any such Shelf Registration Beneficiary, furnish to such Shelf Registration Beneficiary a reasonable number of copies of, a supplement or amendment to such prospectus (if such a supplement or amendment is required under the Securities Act) so that, as thereafter delivered to the purchasers of such Shares, such prospectus will not contain an untrue statement of a material fact or omit to   
 
5 

state any fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made, (ii) when the prospectus or any supplement or post-effective amendment has been filed, and, with respect to the Shelf Registration Statement or any post-effective amendment, when the same has become effective under the Securities Act (including in such notice a written statement that any Shelf Registration Beneficiary may, upon request, obtain, at the sole expense of Alcoa, one conformed copy of the Shelf Registration Statement or post-effective amendment including financial statements and schedules, documents incorporated or deemed to be incorporated by reference and exhibits), (iii) if at any time when a prospectus is required by the Securities Act to be delivered in connection with sales of the Shares the representations and warranties of Alcoa contained in any agreement entered into pursuant to (f) below (including any underwriting agreement) cease to be true and correct in all material respects, (iv) of the receipt by Alcoa of any notification with respect to the suspension of the qualification or exemption from qualification of the Shelf Registration Statement or the Shares for offer or sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose, and (v) of Alcoa’s determination that a post-effective amendment to the Shelf Registration Statement would be appropriate. 
 
(d) otherwise use its best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement (which need not be audited) covering the period of at least twelve months beginning with the first day of the first full calendar quarter of Alcoa after the effective date of the Shelf Registration Statement, which earnings statement shall satisfy the provisions of section 11(a) of the Securities Act and Rule 158 thereunder; 
 
(e) in the event of the issuance of any stop order suspending the effectiveness of the Shelf Registration Statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any securities included in the Shelf Registration Statement for sale in any jurisdiction, Alcoa will (i) promptly notify each Shelf Registration Beneficiary of such stop order, and (ii) use its best efforts promptly to obtain the withdrawal of such order; 
 
(f) in the case of an underwritten offering during the Effectiveness Period, enter into such customary agreements (including underwriting agreements in customary form) and take all such other actions as the Shelf Registration Beneficiary or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Shares (but not including any “road-show” participation by management of Alcoa) and cause to be delivered to the underwriters and the Shelf Registration Beneficiary, if any, at the expense of Alcoa, opinions of counsel to Alcoa and “comfort letters” from the auditors to Alcoa in customary form, covering such matters as are customarily covered by opinions and “comfort letters” for an underwritten public offering as the underwriters may reasonably request and addressed to the underwriters and the Shelf Registration Beneficiary; 
 
(g) Notwithstanding anything to the contrary contained in this Agreement, 
 
 	(1)	 	Right to Impose Delay Periods. Alcoa shall have the right to delay the effectiveness of the Shelf Registration Statement or to suspend the right of a

If a Delay Period is in effect, until the end of the Delay Period, the Camargo Group and its Affiliates and the Permitted Sellers shall cease all efforts to offer or sell any of the Shares under the effective Shelf Registration Statement and shall not disclose to any third party the fact that a Delay Period is in effect.

 	under this Agreement may only be assigned to a Transferee acquiring Shares in a Transfer if such Transfer cannot reasonably be accomplished under the Shelf Registration Statement or under Rule 144 of the Securities Act by the proposed closing date of the proposed Transfer.

Furthermore, each such Transferee (other than the Camargo Group and its Affiliates) shall be eligible to reassign in whole its rights and obligations under this Agreement only once to one subsequent Transferee of the Shares (who shall have no further assignment rights) if such subsequent Transfer cannot reasonably be accomplished under the Shelf Registration Statement or under Rule 144 of the Securities Act by the proposed closing date of the proposed Transfer and provided that under all circumstances the total number of Transferees (other than the Camargo Group and its Affiliates) eligible at any given time to be Permitted Sellers under this Agreement is subject to the limitation set forth in this clause (B). The Camargo Group and its Affiliates shall: (i) give prior written notice to Alcoa in accordance with Section 7.6 of the Principal Agreement of any assignment by it of the rights and obligations of this Agreement hereunder (which notice may be included as part of the Proposed Sale Notice); (ii) ensure that the assignee agrees to all restrictions and obligations imposed under this Agreement; (iii) ensure that the assignee agrees to the provisions of this Section 4.2(g)(4), including those relating to any reassignment by it, and agrees to give prior written notice to Alcoa in accordance with the provisions of Section 5.4 of any such reassignment.

(i) make available for inspection by any Shelf Registration Beneficiary selling Shares, any underwriter participating in any such disposition of Shares, if any, and any attorney, accountant or other agent retained by any such Shelf Registration Beneficiary, or underwriter (collectively, the “Inspectors”), at the offices where normally kept, during reasonable business hours, all financial and other records, pertinent corporate documents and instruments of Alcoa and its subsidiaries (collectively, the “Records”) as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the officers, directors and employees of Alcoa and its subsidiaries to supply all information reasonably requested by any such Inspector in connection with the Shelf Registration Statement and prospectus, and each Inspector shall agree in writing pursuant to confidentiality agreements on customary terms to keep the Records confidential; and 
 
(j) cooperate with each Shelf Registration Beneficiary selling Shares and each underwriter, if any, participating in the disposition of such Shares and their respective counsel in connection with any filings required to be made with the National Association of Securities Dealers, Inc. (the “NASD”). 
 
4.3 Shelf Registration Beneficiary Information. Each Shelf Registration Beneficiary shall furnish to Alcoa such information regarding such Shelf Registration Beneficiary and the distribution of Shares proposed by such Shelf Registration Beneficiary as Alcoa may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification, or compliance referred to in this Article IV. 
 
4.4 Registration Expenses. 
 
(a) Except as expressly provided in this Article IV, Alcoa shall pay all Registration Expenses relating to the Shelf Registration. “Registration Expenses” shall mean any and all fees and expenses incident to Alcoa’s performance of or compliance with this Article IV, including: (i) SEC, stock exchange or NASD registration and filing fees, (ii) fees and expenses of compliance with U.S. state securities or “blue sky” laws and in connection with the preparation of a “blue sky” survey, including reasonable fees and expenses of blue sky counsel, (iii) printing expenses, (iv) messenger and delivery expenses related to distributing prospectuses in preliminary and final form as well as any supplements thereto, (v) fees and disbursements of counsel for Alcoa, (vi) fees and expenses of Alcoa’s auditors in connection with the preparation and delivery of any “comfort letters” reasonably required by the underwriter(s), and (vii) fees and disbursements of all independent public accountants and fees and expenses of other Persons, including special experts, retained by Alcoa. 
 
(b) Notwithstanding the foregoing, (i) the provisions of this Article IV shall be deemed amended to the extent necessary to cause these expense provisions to comply with “blue sky” laws of each state within the U.S. in which the offering is made and (ii) in connection with the Shelf Registration, each Shelf Registration Beneficiary shall pay all underwriting discounts   
 
10 

and commissions and transfer taxes, if any, attributable to the Shares included in the offering by the Shelf Registration Beneficiary and all fees and expenses of such Shelf Registration Beneficiary’s counsel. 
 
4.5 Indemnification. 
 
(a) Alcoa agrees to indemnify and hold harmless, to the extent permitted by law, each Shelf Registration Beneficiary and underwriter of any underwritten transaction, their respective officers, directors and Affiliates against any losses, claims, damages or liabilities to which such Shelf Registration Beneficiary and underwriter or any such director, officer, or Affiliate may become subject under the Securities Act or otherwise, insofar as such losses, claims damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained (A) in the Shelf Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto used in connection with this Article IV or (B) in any application or other document or communication (in this Section 4.5 collectively called an “application”) executed by or on behalf of Alcoa or based upon written information furnished by or on behalf of Alcoa filed in any jurisdiction in order to qualify any securities covered by the Shelf Registration Statement under the “blue sky” or securities laws thereof, or (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading contained (A) in the Shelf Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto used in this Article IV or (B) in any application executed by or on behalf of Alcoa or based upon written information furnished by or on behalf of Alcoa filed in any jurisdiction in order to qualify any securities covered by the Shelf Registration Statement under the “blue sky” or securities laws thereof, and Alcoa will reimburse the Shelf Registration Beneficiary and underwriter and each such director, officer and Affiliate for any legal or any other expenses incurred by them, as such expenses are incurred, in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided that Alcoa shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or omission made in any such prospectus or preliminary prospectus or any amendment or supplement thereto, or in any application, in reliance upon and in conformity with written information prepared and furnished to Alcoa by any Shelf Registration Beneficiary or underwriter expressly for use therein or by any Shelf Registration Beneficiary’s or underwriter’s failure to deliver a copy of the prospectus or any amendments or supplements thereto after Alcoa has furnished any Shelf Registration Beneficiary or underwriter with a sufficient number of copies of the same. 
 
(b) In connection with the Shelf Registration, such Shelf Registration Beneficiary and underwriter will furnish to Alcoa in writing such information and documents concerning such Shelf Registration Beneficiary or underwriter as Alcoa reasonably requests for use in connection with the Shelf Registration Statement or any prospectus and, to the extent permitted by law, will indemnify and hold harmless Alcoa and its directors, officers and Affiliates against any losses, claims, damages or liabilities to which Alcoa or any such director, officer or Affiliate may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise   
 
11 

out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Shelf Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or in any application or (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue or alleged untrue statement or omission or alleged omission is made in the Shelf Registration Statement, any such prospectus or preliminary prospectus or any amendment thereof or supplement thereto, or in any application, in reliance upon and in conformity with written information concerning such Shelf Registration Beneficiary or underwriter prepared and furnished to Alcoa by or on behalf of such Shelf Registration Beneficiary or underwriter in writing expressly for use therein, and each Shelf Registration Beneficiary will reimburse Alcoa and each such director, officer and Affiliate for any legal or any other expenses incurred by them, as such expenses are incurred, in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided that the obligation to indemnify will be individual to each Shelf Registration Beneficiary and underwriter and will be limited to the net amount of proceeds received by such Shelf Registration Beneficiary and underwriter from the sale of Shares by such Shelf Registration Beneficiary or underwriter pursuant to the Shelf Registration Statement. 
 
(c) Any Person entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified parties and the indemnifying party may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder unless the failure to give such notice is materially prejudicial to an indemnifying party’s ability to defend such action. If such defense is assumed, the indemnified party will not be subject to any liability for any settlement made by the indemnifying party without its consent (but such consent will not be unreasonably withheld). Anything to the contrary appearing in this Agreement notwithstanding, an indemnifying party will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified hereunder with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. If an indemnifying party assumes the defense, the indemnified party may engage its own counsel at its own sole cost and expense. All fees and expenses of counsel to any indemnified party required to be paid by the indemnifying party shall be paid by the indemnifying party as incurred by such indemnified party. 
 
(d) The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, Affiliate or controlling or controlled Person of such indemnified party and will survive the transfer of Shares by any Shelf Registration Beneficiary or underwriter. If the indemnification provided for herein is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or   
 
12 

liabilities in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the indemnified party or parties, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations; the relative fault of the indemnifying party on the one hand and of the indemnified party on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, and by such party’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, that in no event shall any contribution by any Shelf Registration Beneficiary or underwriter or any director, officer, Affiliate or controlling or controlled Person thereof exceed the amount of the net proceeds received by such Shelf Registration Beneficiary or underwriter from the sale of Shares pursuant to such registration statement. 
 
4.6 Current Public Information. At all times prior to the earlier of the second anniversary of the Closing Date and the date on which each Permitted Seller has disposed of all of such Permitted Seller’s Shares, Alcoa will file all reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder to the extent required to enable the Permitted Seller to sell Shares pursuant to Rule 144.

The Permitted Seller may disclose such information to its officers, directors, employees, accountants, counsel, consultants, advisors and agents who have a need to know such information in connection with the transactions contemplated by this Agreement so long as such persons are informed by the Permitted Seller of the confidential nature of such information and are obligated by the Permitted Seller to treat such information confidentially. Notwithstanding the foregoing, the Permitted Seller may disclose the tax treatment and tax structure of the transactions contemplated by this Agreement (including any materials, opinions or analyses relating to such tax treatment or tax structure, but without disclosure of identifying information or, except to the extent relating to such tax structure or tax treatment, any nonpublic commercial or financial information). Moreover, notwithstanding any other provision of this Agreement, there shall be no limitation on the Permitted Seller’s ability to consult any tax adviser, whether or not independent from the Permitted Seller, regarding the tax treatment or tax structure of the transactions contemplated by this Agreement.

Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective legal representatives, successors, heirs and permitted assigns (including the Permitted Sellers), and no other Person has any right, benefit or obligation hereunder. 
 
5.8 Waiver. The waiver by any party or any Permitted Seller of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any subsequent breach.

5.14 Dispute Resolution. In an effort to resolve informally and amicably any dispute or controversy which might arise between the parties or between Alcoa and a Permitted Seller (a “party” for purposes of the remainder of this provision) with respect to this Agreement, without first resorting to any third party or tribunal for resolution, the parties shall first endeavor to resolve the matter through direct discussions and negotiations. If the matter cannot be settled, it shall be referred by each party to a responsible officer of each of Alcoa and Camargo Corrêa. If the two officers are unable to resolve the matter within 30 days of its referral, the matter will be referred to the Chief Executive Officers of Alcoa and Camargo Corrêa. If settlement is not thereafter reached through their efforts within an additional 30 days, or such longer time period as they may agree, then either party may initiate arbitration proceedings to resolve the matter. Any such dispute, controversy or claim in connection with this Agreement, including its validity, interpretation, application, scope, enforceability, performance, breach and termination, shall be resolved exclusively and finally by arbitration, to the exclusion of the courts. Notice of arbitration shall be deemed proper if made in accordance with Section 5.4 of this Agreement. If the parties fail to agree in writing on the place where the arbitration is to be conducted, such arbitration shall be held in New York, New York, United States of America. Arbitration shall be conducted in English, pursuant to International Chamber of Commerce (“ICC”) Arbitration Rules in force at the time of the arbitration, by a panel of three arbitrators who are fluent in the English language and who are skilled in the legal and business aspects of the subject matter of this Agreement. The arbitrators shall be appointed in accordance with ICC Rules. Any monetary award made pursuant to such arbitration shall be calculated and paid exclusively in Dollars. Judgment upon the award rendered may be entered in any court having jurisdiction, or an application may be made to any court for a judicial acceptance of the award and an order of enforcement, as the case may be. Each of the parties hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any Federal court of the United States of America sitting in New York City and any appellate court from any thereof for recognition or enforcement of any such judgment. Each party hereby irrevocably and unconditionally waives any objection (including any defense of inconvenient forum) which it may now or hereafter have to the laying of such venue, and each party irrevocably consents to service of process in the manner provided for notices in Section 5.4. 
 
5.15 Entire Agreement and Modifications. This Agreement and the Principal Agreement, together with the exhibits thereto, constitute the entire agreement between the parties with respect to the subject matter hereof and supersede all prior agreements,   
 
16 

understandings, negotiations and discussions, whether oral or written, of the parties. No supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the party to be bound thereby. 
 
IN WITNESS WHEREOF, the parties hereto have executed this Agreement, or have caused this Agreement to be duly executed on their respective behalf by their duly authorized representative, as of the day and year first above written.
