PART I

ITEMS 1 AND 2: BUSINESS AND PROPERTIES

        Apex Silver Mines Limited, incorporated under the laws of the Cayman Islands in 1996, is engaged in the exploration and development of silver properties in South America, Mexico, Central America and Central Asia. We have a large diversified portfolio of privately owned and controlled silver exploration properties. We have rights to or control over 100 silver and other mineral exploration holdings, divided into 34 property groups, located in or near the traditional silver producing regions of Bolivia, Mexico, Peru, El Salvador and Kyrgyzstan. Our exploration efforts have produced our first development property, our 100% owned San Cristobal Project located in southern Bolivia. San Cristobal's proven and probable reserves, based on $4.62 per ounce silver, $0.38 per pound zinc and $0.22 per pound lead, total approximately 211 million tonnes of ore grading 65.81 grams per tonne of silver, 1.63% zinc and 0.61% lead, containing approximately 446 million ounces of silver, 7.6 billion pounds of zinc and 2.8 billion pounds of lead. The prices used represent the three year average price for each of the metals as per guidelines established by the Securities and Exchange Commission. None of our properties is in production, and consequently we have no operating income or cash flow.

        As used herein, Apex Limited, we and our refer collectively to Apex Silver Mines Limited, its predecessors, subsidiaries and affiliates or to one or more of them as the context may require.

        All currency references are to United States dollars, unless otherwise indicated.

AVAILABLE INFORMATION

        We make available, free of charge through our Internet web site at http://www.apexsilver.com, our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as soon as reasonably practicable after such material is electronically filed with or furnished to the SEC.

BUSINESS STRATEGY

        Apex Limited is one of a limited number of mining companies which focuses on silver exploration, development and production. Our strategy is to capitalize on the San Cristobal Project and our sizeable portfolio of silver exploration properties in order to achieve long-term profits and growth and to enhance shareholder value.

        Although our primary focus is on mining silver, we intend to produce other metals associated with our silver deposits if economically practicable, including zinc, lead, copper and gold. We are managed by a team of seasoned mining professionals with significant experience in the construction, development and operation of large scale, open pit and underground, precious and base metals mining operations, as well as the identification and exploration of mineral properties.

        The principal elements of our business strategy are to:

•

Secure financing for and proceed to develop the San Cristobal Project into a large scale open pit mining operation;



•

Continue to explore and develop those properties which we believe are most likely to contain significant amounts of silver and divesting those properties that are not of continuing interest; and



•

Identify and acquire additional mining and mineral properties that we believe contain significant amounts of silver or have exploration potential.

SAN CRISTOBAL PROJECT

        Our 100% owned San Cristobal Project is located in the San Cristobal mining district of the Potosi Department in southern Bolivia, a region that has historically produced a significant portion of the world's silver supply. San Cristobal is located in the Bolivian Altiplano in the Andes mountains, approximately 500 kilometers south of the city of La Paz, which is the seat of government where executive and legislative powers reside. The project is accessible by a gravel road from the international railroad at Rio Grande, approximately 50 kilometers to the north, and from the town of Uyuni, a former railroad maintenance town, approximately 100 kilometers to the northeast. The railroad begins at the Chilean port of Antofagasta, approximately 460 kilometers southwest of San Cristobal, and continues north to La Paz.

        The San Cristobal property is comprised of certain mining concessions which are part of a large block of concessions covering approximately 480,000 acres which we own or control. In addition, we have acquired rights to approximately 200,000 acres for transportation and power lines. Under these mining concessions, we have the right to carry out exploration, mining, processing and marketing of all mineral substances located within the concessions, and to use the water found on the concessions. In order to maintain our rights to these concessions, we must make annual mining patent payments to the Bolivian government.

        Our San Cristobal property is largely unexploited. The relatively small, shut down Toldos mine, located approximately 1.5 kilometers from the proposed San Cristobal open pit mine, was mined by underground block caving and open pit mining between 1985 and 1995. At present, there is no significant mining or processing plant or equipment on the San Cristobal property.

        We believe that our San Cristobal property contains one of the largest known open pit silver-lead-zinc deposits in the world. Current proven and probable reserves at San Cristobal, total approximately 211 million tonnes of ore grading 65.81 grams per tonne of silver, 1.63% zinc and 0.61% lead. These reserves contain approximately 446 million ounces of silver, 7.6 billion pounds of zinc and 2.8 billion pounds of lead. The reserves are based on $4.62 per ounce silver, $0.38 per pound zinc and $0.22 per pound lead. These prices represent the three year average prices for each of the metals as per guidelines established by the Securities and Exchange Commission. The full dimensions of the San Cristobal deposit have not yet been determined; mineralized material extends outward from the identified ore body in most directions as well as to depths below 260 meters, the currently defined pit bottom.

        In September 1999, we completed a detailed feasibility study on San Cristobal. The feasibility study was prepared by Kvaerner, E&C Metals Division, an independent engineering firm. Based on the feasibility study, we anticipate developing a low cost, open pit silver-zinc mine at San Cristobal with a low strip ratio of approximately 1.8:1 (tonnes of waste per tonne of ore), including pre-stripping. Under the study's mine plan, we would mine the deposit at a rate of approximately 40,000 tonnes of ore per day and process the ore by conventional flotation methods. We would transport mined ore to the primary crusher by truck and then convey the crushed ore to a mill and flotation plant. The ore would be ground in semi-autogenous (SAG) and ball mill circuits, and then processed by selective flotation to produce separate zinc-silver and lead-silver concentrates and lesser amounts of silver bulk concentrates. We expect to transport the filtered concentrates by road or railroad to a port in Chile, and then by ocean vessel to smelters and refineries in Asia, the Americas and Europe.

        In September 2000, we announced that positive metallurgical and operational improvements occurring subsequent to completion of the San Cristobal feasibility study had further enhanced the project economics. Once commercial production is attained, we believe the operation should produce an annual average of approximately 21 million contained ounces of silver, 478 million contained pounds of zinc and 155 million contained pounds of lead over a mine life of approximately 15 years, with higher metal production anticipated in the first five years. Based on the geology of San Cristobal, and the drilling, analysis and proven and probable reserves identified to date, we believe that the San Cristobal Project could be extended in life or increased in scale.

2

        We have spent approximately $98 million in project capital at San Cristobal, including approximately $33 million in construction costs, through December 31, 2003. Based on certain revisions made during 2000 to the September 1999 feasibility study for the San Cristobal Project, which assumes contract mining, we forecast additional capital costs for construction to total approximately $435 million, net of approximately $60 million in expected tax credits, including approximately $25 million which will be recovered against our future Bolivian income taxes after commencement of production. We believe capital costs have increased since this estimate was made, but have not yet updated the capital cost estimate.

        Life-of-mine average cash operating cost for San Cristobal is currently forecast to average approximately $1.95 per ounce of silver, net of lead by-product credits, and $0.27 per pound of zinc. For the first five years of production, the average cash operating cost per ounce of silver, net of lead by-product credits, is projected to be $1.23 and the average cash operating cost per pound of zinc is projected to be $0.23. Operating cash cost is a non-GAAP financial measure. Our estimated operating costs include estimated mining, milling and mine-related overhead costs, and exclude taxes, depreciation and amortization. The average cash operating cost per ounce of silver is equal to the pro-rata share of estimated average operating costs for the period divided by the estimated number of ounces of silver to be produced during the period reduced by the ounces required to cover estimated refining, treatment and transportation charges for the period with the result further reduced by estimated lead byproduct credits for the period. Average cash operating cost per pound of zinc is equal to the pro-rata share of estimated average operating costs for the period divided by the estimated number of pounds of zinc to be produced during the period reduced by the pounds required to cover estimated refining, treatment and transportation charges for the period. We have included estimated average cash operating cost information to provide investors with information about the cash generating capabilities of our San Cristobal Project. This information will differ from measures of performance determined in accordance with generally accepted accounting principles (GAAP) and should not be considered in isolation or as a substitute for measures of performance that will be prepared in accordance with GAAP. These measures are not necessarily indicative of operating profit or cash flow from operations to be determined under GAAP and may not be comparable to similarly titled measures of other companies.

        Due primarily to weak silver prices, we reduced spending on San Cristobal development during 2001 through 2003. We advanced the project during this period primarily by continuing the evaluation and negotiation of infrastructure arrangements, including the selection of a port from which to ship the concentrates to smelters and arrangements for the transportation of concentrates from San Cristobal to the port and the provision of power to San Cristobal.

        In 2003, we entered into long-term contracts for the truck and rail transportation of concentrates from San Cristobal and for the use of the port in Mejillones, Chile to store, load and export concentrates. Both contracts are subject to typical conditions precedent, including obtaining necessary permits and approvals from Bolivian and Chilean authorities, closing of debt financing for the project and satisfying conditions for the initial borrowing. Both contracts are subject to early termination by either party if these and certain other conditions precedent are not completed by year-end 2004 in the case of the transportation contract and by the end of the first quarter of 2005 in the case of the port contract.

        With the recent increase in silver and zinc prices and our success in raising additional financing through the sale of ordinary shares, we plan to move forward with the development of San Cristobal, and expect to spend approximately $25 million in 2004. During 2004, we plan to engage an engineering and construction firm to complete detailed engineering and incorporate required changes into the development plan for construction of the project. Changes to the development plan may result in an increase in our expected capital costs for construction. We also plan to commence construction of roads and bridges for mine construction access and development and to build mancamps for construction. We expect to complete infrastructure arrangements for transportation and power. We continue to consider several alternatives for power for the San Cristobal Project. We also plan to renew the operating permits for construction and operation of the mine and processing facilities, which expire this year. In addition, we will

3

be working actively towards completion of the financing requirements for San Cristobal if metals and capital markets remain attractive.

        Assuming that the metals markets remain favorable and that we are able to complete the additional financing required for the Project, we expect construction to commence at San Cristobal in the first half of 2005 and start-up and production to commence in 2007.

Geology

        The San Cristobal Project occupies the central portion of a depression associated with volcanism of Miocene age. The 4 kilometer diameter depression is filled with fine to coarse grained volcanoclastic sedimentary rocks (including shale, conglomerate, sandstone, landslide debris and talus). During the late Miocene Period, after sedimentation had nearly filled the depression, a series of dacite and andesite porphyry sills and domes intruded the volcanoclastic rocks. Disseminated and stockwork silver-lead-zinc mineralization formed locally both within the volcanoclastic sediments and in the intrusions themselves. The disseminated mineralization was not mined in the past except at the nearby Toldos mine. Historic production on the San Cristobal property was from veins.

        The two largest areas of mineralization, the Jayula and Tesorera deposits, initially were drilled separately. Our additional drilling in 1998, which more than doubled proven and probable reserves, merged the Jayula and Tesorera deposits into one large deposit, now called the San Cristobal orebody.

        Mineralization at the Jayula portion of the San Cristobal orebody is dominated by stockwork consisting of iron oxides, clays, galena, barite, sphalerite, pyrite, tetrahedrite and acanthite. The veins of the stockwork are most abundant in the dacite sill, near its contact with the volcanoclastic sedimentary rocks. At the Tesorera portion of the orebody, mineralization is characterized by galena, sphalerite and acanthite, disseminated in the volcanoclastic sedimentary rocks. This mineralization is most prevalent in the coarser grained beds, usually conglomerates and coarse sandstones. To the extent that ore grade mineralization is confined to the sedimentary beds, the mineral zones are both stratiform and strata-bound, forming tabular bodies.

        Oxidation of the mineralized zone at San Cristobal has occurred to depths averaging 40 to 75 meters and affects approximately 4% of the reserves. In this oxide zone, zinc has been almost completely leached out by groundwater; silver values, however, are locally enhanced due to secondary enrichment processes. In the oxide zone, the dominant minerals are iron oxides, galena, clays, native silver and secondary acanthite.

Reserves

        We have completed approximately 169,400 meters of reverse circulation and approximately 20,100 meters of diamond drilling at San Cristobal. This drilling indicates that the mineralization is present over an area of 1,500 meters by 1,500 meters. The ore deposit defined by this drilling is open at depth and in several lateral directions.

        Proven and probable reserves were recalculated in February 2004 using a $4.66 net smelter return per tonne cutoff value and reduced market price assumptions of $4.62 per ounce silver, $0.38 per pound zinc and $0.22 per pound lead, reflecting the three year rolling average prices through December 2003. The

4

following tables show our proven and probable reserves of silver, zinc and lead for sulfide ore and oxide ore at the San Cristobal Project, which were calculated by Mine Reserve Associates, Inc.

	Proven and Probable Reserves—San Cristobal Project
	Average Grade				Contained Metals(1)
	Tonnes of ore (000s)	Silver Grade (oz./tonne)	Zinc Grade (%)	Lead Grade (%)	Silver Ounces (000s)	Zinc Tonnes (000s)	Lead Tonnes (000s)
Sulfide Ore	202,069	2.016	1.70	0.60	407,371	3,435	1,212
Oxide Ore	8,901	4.390	0.10	0.64	39,075	9	57

(1)

Amounts are shown as contained metals in ore and therefore do not reflect losses in the recovery process. Sulfide ore reserves are expected to have an approximate average recovery of 75% for silver, 92% for zinc and 87% for lead. Oxide ore reserves are expected to have an average recovery of 60% for silver and 50% for lead.

Republic of Bolivia

        Bolivia is situated in central South America and is bordered by Peru, Brazil, Paraguay, Argentina and Chile. It has an area of approximately 1.1 million square kilometers and a population of approximately 8.5 million people. Bolivia's official and most widely spoken language is Spanish, but over 70 percent of the population is either native Aymara or Quechua Indian.

        Bolivia has experienced slow economic growth and increasing political and economic instability in the last three years. In late 2003, there were violent demonstrations in La Paz and elsewhere in Bolivia, protesting the free-trade policies of the Bolivian government and specifically the proposed export of natural gas to the U.S. through Chile and the impact of U.S. policies regarding the drug trade. These demonstrations resulted in the resignation of President Sanchez de Lozada, in October 2003, and his constitutional replacement by President Mesa. Although to date these conditions and events have not caused any adverse impact on our San Cristobal Project, there can be no assurance regarding when or whether these political and economic uncertainties will be successfully resolved, that the political and economic climate may not become more unstable or that the political and economic uncertainties would not have an adverse impact on the development of San Cristobal.

        Bolivian law provides for unrestricted repatriation of capital, freedom to import goods and services, equality under the law between foreign and domestic companies, and the creation of "free trade zones."

        Mining companies in Bolivia are subject to a 25% income tax, with taxable income determined in accordance with Bolivian generally accepted accounting principles. Mining companies are also subject to a complementary mining tax, creditable against the income tax, ranging from 3% to 7% of revenue generated from product sales. Bolivian source income, including dividends and interest, is subject to a 12.5% withholding tax. Other taxes include import taxes of 5% on capital goods and 10% on other imports, and value added tax (VAT) of 13%. As an exporter, we will be able to apply for a refund of import duties and VAT paid on imports and raw materials included in the cost of exported goods, limited to 13% of the total value of the exports. We previously entered into an agreement with the government of Bolivia pursuant to which we would receive a certain portion of VAT refunds prior to the commencement of production. That agreement has since expired and we will be seeking to enter into a new agreement.

        All mineral deposits in Bolivia are the property of the State. Mining concessions awarded by the State grant the holder, subject to certain payments, the exclusive right to carry out prospecting, exploration, exploitation, concentration, smelting, refining and marketing activities with respect to all mineral substances located within a given concession. Under Bolivian law, local and foreign companies are treated equally in obtaining mineral concessions. With respect to nationalized and other concessions still held by State-owned Comibol, private investors may inter into joint venture, lease or services agreements with

5

Comibol. Holders of mining concessions are obliged to pay an annual mining patent, the fees for which are progressive and are based on the number of years of existence of the concession. Mining concessions are liable to forfeiture when the corresponding annual patent fails to be paid. Concessions established before the enactment of the New Mining Code in 1997 which comprise an area of more than 1,000 mining claims pay the equivalent of $1.00 per claim per year for the first five years of the existence of the concession; thereafter, the patent increases to the equivalent of $2.00 per claim per year. Concessions established under the New Mining Code pay the following: for the first five years of the existence of a concession, the owner is required to pay the equivalent of $25.00 per square per year; thereafter the patent increases to the equivalent of $50.00 per square per year. Most of our Bolivian concessions were established prior to enactment of the New Mining Code.

        Bolivia has a national environmental policy to protect the environment, promote sustainable development, promote the preservation of biological diversity and promote environmental education. Under Bolivia's environmental regulations, environmental impact assessments are required, and concession holders must maintain waterways running through their concessions in their unspoiled state, employ exploration and development techniques that minimize environmental damage and minimize damage to surface rights, to neighboring concessions and to the environment. In practice, foreign mining companies operating in Bolivia generally adhere to U.S. and European environmental standards for mining and exploration.

        Bolivia has experienced high levels of unemployment and underemployment. Bolivia has a large pool of unskilled and, in the mining sector, semi-skilled labor, but a relative shortage of skilled labor and managerial expertise overall. A large portion of the labor force that is engaged in wage employment is also unionized, although union participation is not mandatory and collective bargaining agreements are very rare, as negotiations are generally carried out between an individual company's union and management.

EXPLORATION

        Other than San Cristobal, we have a portfolio of silver properties in Bolivia, Mexico, Peru and Central Asia totaling approximately 760,000 acres which contain potential for silver mineralization or other significant exploration potential. These mineral properties typically consist of:

•

concessions which we have acquired, or applied for directly;



•

concessions which we have leased, typically with an option to purchase; and



•

concessions which we have agreed to explore and develop and, if feasible, bring into production, in concert with joint venture partners.

        We generally seek to structure our acquisitions of mineral rights so that individual properties can be optioned for exploration and subsequently acquired at reasonable cost if justified by exploration results. Properties which we determine do not warrant further exploration or development expenditures are divested, typically without further financial obligation to us. Although we believe that our exploration properties may contain significant silver and/or other mineralization, our analysis of most of these properties is at a preliminary stage. The activities performed to date at these properties often have involved the analysis of data from previous exploration efforts by others, supplemented by our own exploration programs.

6

        Our exploration holdings consist primarily of ownership interests, leases, options and joint ventures, all in varying percentages. The distribution of these holdings is summarized in the table below. Acreage amounts shown below represent a 100% interest.

Location and Distribution of Exploration Properties

Country				Number of Exploration Property Groups	Acreage
Mexico				7	131,000
South America
	Bolivia			17	355,000
	Peru			27	110,000
		Subtotal		44	465,000
Central Asia				2	164,000
			Total	53	760,000

        We believe that our most interesting exploration property is Platosa-Saltillera, located in Durango State in northern Mexico. Our joint venture partners have initiated a test mining program on a small portion of the property in which we did not choose to participate. We have retained a net smelter return royalty on this mining project. During 2004, the joint venture will map and sample an additional 9,766 hectares exploration project at Platosa-Saltillera. In addition to Platosa-Saltillera, we have holdings in Mexico in the historic Zacatecas mining district as well as several other silver properties in the States of Guerrero, Durango and Zacatecas.

        We also have holdings, joint ventures and options in Bolivia, other than the San Cristobal Project, including a property in the historic Pulacayo silver mining district. We have an exploration office in Lima and are actively exploring for silver in Peru, the world's second largest silver producing country. We have acquired the mineral rights to several historic silver districts in the northeastern and southeastern parts of the country. In Central Asia, we have two mineral prospecting licenses in Kyrgyzstan.

        We continue to explore options designed to achieve full recognition of the value of our exploration portfolio, including the possibility of forming a subsidiary into which we may consolidate most of our exploration properties outside the San Cristobal District. If we elect to proceed with SilEx, SilEx may become an independently funded exploration subsidiary focused on silver, gold and precious metal deposits and polymetallic deposits containing precious metals.

RISK FACTORS

        Investors in Apex Limited should consider carefully, in addition to the other information contained in, or incorporated by reference into, this report, the following risk factors:

We have no history of production.

        We have no history of producing silver or other metals. The development of our economically feasible properties will require the construction or rehabilitation and operation of mines, processing plants and related infrastructure. As a result, we are subject to all of the risks associated with establishing new mining operations and business enterprises. There can be no assurance that we will successfully establish mining operations or profitably produce silver or other metals at any of our properties.

We have a history of losses and we expect losses to continue for at least the next three years.

        As an exploration and development company that has no production history, we have incurred losses since our inception, and we expect to continue to incur additional losses for at least the next three years. As of December 31, 2003, we had an accumulated deficit of $78.8 million. There can be no assurance that we will achieve or sustain profitability in the future.

The estimates of our reserves and other mineralization estimates are potentially inaccurate.

        Unless otherwise indicated, reserves and other mineralization figures presented in our filings with the Securities and Exchange Commission, press releases and other public statements that may be made from time to time are based on estimates of contained silver and other metals made by independent geologists or our own personnel. These estimates are imprecise and depend on geological interpretation and statistical inferences drawn from drilling and sampling which may prove to be unreliable. There can be no assurance that:

•

these estimates will be accurate;



•

reserves and other mineralization figures will be accurate; or



•

reserves or mineralization could be mined and processed profitably.

        Since we have not commenced production on any of our properties, reserves and other mineralization estimates may require adjustments or downward revisions based on actual production experience. Extended declines in market prices for silver, zinc and lead may render portions of our reserves uneconomic and result in reduced reported reserves. Any material reductions in estimates of our reserves and other mineralization, or of our ability to extract these reserves or mineralization, could have a material adverse effect on our results of operations and financial condition.

        We have not established the presence of any proven or probable reserves at any of our mineral properties other than the San Cristobal Project. There can be no assurance that subsequent testing or future feasibility studies will establish additional reserves at our properties. The failure to establish additional reserves could restrict our ability to successfully implement our strategies for long term growth beyond the San Cristobal Project.

The San Cristobal Project is subject to risks including delays in commencement and completion and we may be unable to achieve anticipated production volume or manage cost increases.

        Completion of the development of the San Cristobal Project is subject to various factors, including the maintaining of recent price levels for silver and zinc, the availability, terms, conditions and timing of acceptable arrangements for financing, power, transportation, construction, contract mining and smelting, and required government approvals, including renewal of the construction and operations permit, and the performance of our engineering and construction contractor and suppliers and consultants. The lack of

8

availability on acceptable terms or the delay in any one or more of the other items listed above could also delay or prevent the development of San Cristobal. There can be no assurance:

•

when or whether the San Cristobal Project will be completed;



•

whether the resulting operations will achieve the anticipated production volume; or



•

that the construction costs and ongoing operating costs associated with the development of the San Cristobal Project will not be higher than anticipated.

        We have never developed or operated a mine or managed a significant mine development project. We cannot assure you that the development of San Cristobal will be completed at the cost and on the schedule predicted, or that silver, zinc and lead grades and recoveries, production rates or anticipated capital or operating costs will be achieved.

        If the actual cost to complete the development of the San Cristobal Project is significantly higher than currently expected, there can be no assurance that we will have enough funds to cover these costs or that we would be able to obtain alternative sources of financing to cover these costs. Unexpected cost increases, reduced silver and zinc prices or the failure to obtain necessary project financing on acceptable terms to commence or complete the development of the San Cristobal Project on a timely basis, or to achieve anticipated production capacity, could have a material adverse effect on our future results of operations and financial condition.

        The successful development of the San Cristobal Project is also subject to the other risk factors described herein.

We depend on a single mining project.

        We anticipate that the majority, if not all, of any revenues for the next few years and beyond will be derived from the sale of metals mined at the San Cristobal Project. Therefore, if we are unable to complete and successfully mine the San Cristobal Project, our ability to generate revenue and profits would be materially adversely affected.

Our success will depend on our ability to manage our growth.

        We anticipate that as we develop San Cristobal and bring it into production and as we acquire additional mineral rights, we will experience significant growth in our operations. We expect this growth to create new positions and responsibilities for management personnel and to increase substantially demands on our operating and financial systems. There can be no assurance that we will successfully meet these demands and manage our anticipated growth.

Our profitability will be affected by changes in the prices of metals.

        Our profitability and long-term viability depend, in large part, on the market price of silver, zinc, lead and other metals. The market prices for these metals are volatile and are affected by numerous factors beyond our control, including:

•

global or regional consumption patterns;



•

supply of, and demand for, silver, zinc, lead and other metals;



•

speculative activities;



•

expectations for inflation; and



•

political and economic conditions.

9

        The aggregate effect of these factors on metals prices is impossible for us to predict. Decreases in metals prices have delayed, and could in the future adversely affect, our ability to finance the development of the San Cristobal Project and the exploration and development of our other properties, which would have a material adverse effect on our financial condition and results of operations. There can be no assurance that metals prices will not decline.

        The following table sets forth for the periods indicated (1) the Comex nearby active silver futures contract's high and low price of silver in U.S. dollars per troy ounce and (2) the London Metals Exchange's high and low settlement prices of zinc and lead in U.S. dollars per pound.

        The closing prices of silver, zinc and lead on March 5, 2004 were $6.99 per troy ounce, $0.51 per pound, and $0.39 per pound, respectively.

We may not be successful in hedging against price, currency and interest rate fluctuations and may incur mark to market losses and lose money through our hedging programs.

        We have engaged in limited metals trading activities to hedge against commodity and base metals price risks, using puts and calls. We may also engage in activities to hedge the risk of exposure to currency and interest rate fluctuations related to the development of San Cristobal in Bolivia or in other countries in which we incur substantial expenditures for exploration or development. Further, terms of our financing arrangements may require us to hedge against these risks. We anticipate that as we bring our mineral properties into production and we begin to generate revenue, we may utilize various price hedging techniques to mitigate some of the risks associated with fluctuations in the prices of the metals we produce.

        There can be no assurance that we will be able to successfully hedge against price, currency and interest rate fluctuations. In addition, our ability to hedge against zinc and lead price risk in a timely manner may be adversely affected by the smaller volume of transactions in both the zinc and lead markets. Further, there can be no assurance that the use of hedging techniques will always be to our benefit. Hedging instruments which protect against market price volatility may prevent us from realizing the benefit from subsequent increases in market prices with respect to covered production. This limitation would limit our revenues and profits. Hedging contracts are also subject to the risk that the other party may be unable or unwilling to perform its obligations under these contracts. Any significant nonperformance could have a material adverse effect on our financial condition and results of operations.

The exploration of mineral properties is highly speculative in nature, involves substantial expenditures and is frequently non-productive.

        Our future growth and profitability will depend, in part, on our ability to identify and acquire additional mineral rights, and on the costs and results of our continued exploration and development programs. Competition for attractive mineral exploration properties is intense. Our strategy is to expand our reserves through a broad program of exploration. Mineral exploration is highly speculative in nature and is frequently non- productive. Substantial expenditures are required to:

•

establish ore reserves through drilling and metallurgical and other testing techniques;



•

determine metal content and metallurgical recovery processes to extract metal from the ore; and

10

•

construct, renovate or expand mining and processing facilities.

        If we discover ore, it usually takes several years from the initial phases of exploration until production is possible. During this time, the economic feasibility of production may change. As a result of these uncertainties, there can be no assurance that we will successfully acquire additional mineral rights, or that our exploration programs will result in new proven and probable reserves in sufficient quantities to justify commercial operations in any of our properties, other than the San Cristobal Project.

        We consider from time to time the acquisition of operating or formerly operating mines. Our decisions to acquire these properties are based on a variety of factors including historical operating results, estimates of and assumptions about future reserves, cash and other operating costs, metals prices and projected economic returns, and evaluations of existing or potential liabilities associated with the property and its operation. Other than historical operating results, all of these may differ significantly from our estimates and assumptions. In addition, there is intense competition for attractive properties. Accordingly, there is no assurance that our acquisition efforts will result in profitable mining operations.

Our profitability depends, in part, on actual economic returns and actual costs of developing mines, which may differ significantly from our estimates and involve unexpected problems and delays.

        None of our mineral properties, including the San Cristobal Project, has an operating history upon which we can base estimates of future cash operating costs. Our decision to develop the San Cristobal Project is based on feasibility studies. Decisions about the development of other projects in the future may also be based on feasibility studies. Feasibility studies derive estimates of reserves and operating costs and project economic returns. Estimates of economic returns are based, in part, on assumptions about future metals prices. Feasibility studies derive estimates of cash operating costs based upon, among other things:

•

anticipated tonnage, grades and metallurgical characteristics of ore to be mined and processed;



•

anticipated recovery rates of silver and other metals from the ore;



•

cash operating costs of comparable facilities and equipment; and



•

anticipated climatic conditions.

        Actual cash operating costs, production and economic returns may differ significantly from those anticipated by our studies and estimates.

        There are a number of uncertainties inherent in the development and construction of any new mine, including the San Cristobal Project. These uncertainties include:

•

the timing and cost, which can be considerable, of the construction of mining and processing facilities;



•

the availability and cost of skilled labor, power, water and transportation;



•

the availability and cost of appropriate smelting and refining arrangements;



•

the need to obtain necessary environmental and other governmental permits, and the timing of those permits; and



•

the availability of funds to finance construction and development activities.

        The costs, timing and complexities of mine construction and development are increased by the remote location of many mining properties, like the San Cristobal Project. It is common in new mining operations to experience unexpected problems and delays during development, construction and mine start-up. In addition, delays in the commencement of mineral production often occur. Accordingly, there is no assurance that our future development activities will result in profitable mining operations.

11

Title to our mineral properties may be challenged.

        Our policy is to seek to confirm the validity of our rights to title to, or contract rights with respect to, each mineral property in which we have a material interest. However, we cannot guarantee that title to our properties will not be challenged. Title insurance generally is not available, and our ability to ensure that we have obtained secure claim to individual mineral properties or mining concessions may be severely constrained. We have not conducted surveys of all of the claims in which we hold direct or indirect interests and, therefore, the precise area and location of these claims may be in doubt. Accordingly, our mineral properties may be subject to prior unregistered agreements, transfers or claims, and title may be affected by, among other things, undetected defects. In addition, we may be unable to operate our properties as permitted or to enforce our rights with respect to our properties.

We may lose rights to properties if we fail to meet payment requirements or development or production schedules.

        We derive the rights to some of our mineral properties, including some of our principal properties at the San Cristobal Project, from leaseholds or purchase option agreements which require the payment of rent or other installment fees. If we fail to make these payments when they are due, our rights to the property may lapse. There can be no assurance that we will always make payments by the requisite payment dates. In addition, some contracts with respect to our mineral properties require development or production schedules. There can be no assurance that we will be able to meet any or all of the development or production schedules. In addition, our ability to transfer or sell our rights to some of our mineral properties requires governmental approvals or third party consents, which may not be granted.

We cannot insure against all of the risks associated with mining.

        The business of mining is subject to a number of risks and hazards, including:

•

adverse environmental effects;



•

industrial accidents;



•

labor disputes;



•

technical difficulties due to unusual or unexpected geologic formations;



•

failures of pit walls; and



•

flooding and periodic interruptions due to inclement or hazardous weather conditions.

        These risks can result in, among other things:

•

damage to, and destruction of, mineral properties or production facilities;



•

personal injury;



•

environmental damage;



•

delays in mining;



•

monetary losses; and



•

legal liability.

        Although we maintain, and intend to continue to maintain, insurance with respect to our operations and mineral properties within ranges of coverage consistent with industry practice, there can be no assurance that insurance will be available at economically feasible premiums. Insurance against environmental risks is not generally available. These environmental risks include potential liability for pollution or other disturbances resulting from mining exploration and production. In addition, not all risks associated

12

with developing and producing silver, zinc, lead and other metals are included in coverage and some covered risks may result in liabilities which exceed policy limits. Further, we may elect to not seek coverage for all risks. The occurrence of an event that is not fully covered, or covered at all, by insurance, could have a material adverse effect on our financial condition and results of operations.

Our San Cristobal Project and our exploration activities are in countries with developing economies and are subject to the risks of political and economic instability associated with these countries.

        We currently conduct exploration activities in countries with developing economies including Bolivia, Mexico and Peru in Latin America. These countries and other emerging markets in which we may conduct operations have from time to time experienced economic or political instability. We may be materially adversely affected by risks associated with conducting operations in countries with developing economies, including:

•

political instability and violence;



•

war and civil disturbance;



•

expropriation or nationalization;



•

changing fiscal regimes;



•

fluctuations in currency exchange rates;



•

high rates of inflation;



•

underdeveloped industrial and economic infrastructure; and



•

unenforceability of contractual rights.

        In particular, Bolivia has experienced slow economic growth and increasing political and economic instability in the last three years. In late 2003, there were violent demonstrations in La Paz and elsewhere in Bolivia, protesting the free-trade policies of the Bolivian government and specifically the proposed export of natural gas to the U.S. through Chile and the impact of U.S. policies regarding the drug trade. These demonstrations resulted in the resignation of President Lozada, in October 2003, and his replacement by President Mesa. Although to date these conditions and events have not caused any adverse impact on our San Cristobal Project, there can be no assurance regarding when or whether these political and economic uncertainties will be successfully resolved, that any political and economic climate may not become more unstable or that the political and economic uncertainties would not have an adverse impact on the development of San Cristobal.

        Changes in mining or investment policies or shifts in the prevailing political climate in any of the countries in which we conduct exploration and development activities could adversely affect our business. Our operations may be affected in varying degrees by government regulations with respect to, among other things:

•

production restrictions;



•

price controls;



•

export and import controls;



•

income and other taxes;



•

maintenance of claims;



•

environmental legislation;



•

foreign ownership restrictions;

13

•

foreign exchange and currency controls;



•

labor;



•

welfare benefit policies;



•

land use;



•

land claims of local residents;



•

water use; and



•

mine safety.

        We cannot accurately predict the effect of these factors. In addition, legislation in the United States regulating foreign trade, investment and taxation could have a material adverse effect on our financial condition and results of operations.

Our activities are subject to foreign environmental laws and regulations which may materially adversely affect our future operations.

        We conduct mineral exploration and development activities primarily in Central America and South America, and are most active in Bolivia, where the San Cristobal Project is located, and Mexico. With the development of San Cristobal, we also expect to conduct mining operations in Bolivia. These countries have laws and regulations which control the exploration and mining of mineral properties and their effects on the environment, including air and water quality, mine reclamation, waste handling and disposal, the protection of different species of flora and fauna and the preservation of lands. These laws and regulations will require us to acquire permits and other authorizations for certain activities. In many countries, including Bolivia, there is relatively new comprehensive environmental legislation, and the permitting and authorization processes may be less established and less predictable than they are in the United States. There can be no assurance that we will be able to acquire necessary permits or authorizations on a timely basis, if at all. Delays in acquiring any permit or authorization could increase the development cost of San Cristobal or other projects and could delay the commencement of production.

        Environmental legislation in many countries is evolving in a manner which will likely require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and a heightened degree of responsibility for companies and their officers, directors and employees. In Bolivia, where there is relatively new environmental legislation, enforcement activities and strategies may be under development, and thus may be less predictable than in the United States. We cannot predict what environmental legislation or regulations will be enacted or adopted in the future or how future laws and regulations will be administered or interpreted. Compliance with more stringent laws and regulations, as well as potentially more vigorous enforcement policies or regulatory agencies or stricter interpretation of existing laws, may (1) necessitate significant capital outlays, (2) cause us to delay, terminate or otherwise change our intended activities with respect to one or more projects and (3) materially adversely affect our future operations.

        Many of our exploration and development properties are located in historic mining districts where prior owners may have caused environmental damage which may not be known to us or to the regulators. In most cases, we have not sought complete environmental analyses of our mineral properties and have not conducted comprehensive reviews of the environmental laws and regulations in every jurisdiction in which we own or control mineral properties. To the extent we are subject to environmental requirements or liabilities, the cost of compliance with these requirements and satisfaction of these liabilities would reduce our net cash flow and could have a material adverse effect on our financial condition and results of operations. If we are unable to fund fully the cost of remediation of any environmental condition, we may be required to suspend operations or enter into interim compliance measures pending completion of the required remediation.

14

We compete against larger and more experienced companies.

        The mining industry is intensely competitive. Many of the largest mining companies are primarily producers of base metals, and may become interested in the types of silver deposits on which we are focused because these deposits typically are polymetallic, containing significant quantities of base metals including zinc, lead and copper. Many of these companies have greater financial resources, operational experience and technical capabilities than we have. We may encounter increasing competition from other mining companies in our efforts to acquire mineral properties and hire experienced mining professionals. Increased competition in our business could adversely affect our ability to attract necessary capital funding or acquire suitable producing properties or prospects for mineral exploration in the future.

Our ability to obtain dividends or other distributions from our subsidiaries may be subject to restrictions imposed by law and foreign currency exchange regulations.

        We conduct, and will continue to conduct, all of our operations through subsidiaries. Our ability to obtain dividends or other distributions from our subsidiaries may be subject to restrictions on dividends or repatriation of earnings under applicable local law, monetary transfer restrictions and foreign currency exchange regulations in the jurisdictions in which the subsidiaries operate. Our subsidiaries' ability to pay dividends or make other distributions to us is also subject to their having sufficient funds to do so. If our subsidiaries are unable to pay dividends or make other distributions, our growth may be inhibited unless we are able to obtain additional debt or equity financing on acceptable terms. In the event of a subsidiary's liquidation, we may lose all or a portion of our investment in that subsidiary.

We may not be able to raise the funds necessary to explore and develop our mineral properties.

        Although we have raised approximately $209 million through equity sales in early 2004, we will need additional external financing to develop and construct the San Cristobal Project and to fund the exploration and development of our other mineral properties. Sources of external financing may include bank borrowings and future debt and equity offerings. There can be no assurance that financing will be available on acceptable terms, or at all. The failure to obtain financing would have a material adverse effect on our growth strategy and our results of operations and financial condition. The mineral properties that we are likely to develop are expected to require significant capital expenditures. There can be no assurance that we will be able to secure the financing necessary to retain our rights to, or to begin or sustain production at, our mineral properties.

We depend on the services of key executives.

        We are dependent on the services of key executives including our chairman and our chief executive officer and a small number of highly skilled and experienced executives and personnel focused on the development of the San Cristobal Project. Due to the relatively small size of Apex Limited, the loss of these persons or our inability to attract and retain additional highly skilled employees required for the development of the San Cristobal Project may delay or otherwise adversely affect the development of the San Cristobal Project, which could have a material adverse effect on our business or future operations.

The substantial control of Apex Limited by our directors, officers and 5% shareholders may have a significant effect in delaying, deferring or preventing a change in control of Apex Limited or other events which could be of benefit to our other shareholders.

        As of March 5, 2004, Thomas S. Kaplan and the other directors of Apex Limited and officers of Apex Silver Mines Corporation, together with members of their families and entities that may be deemed to be affiliates of or related to these persons or entities, and 5% shareholders beneficially owned approximately 25 million shares, or 52%, of our outstanding shares, assuming the conversion of currently exercisable options and warrants. This level of ownership by these persons may have a significant effect in delaying,

15

deferring or preventing a change in control of Apex Limited or other events which could be of benefit to our other shareholders.

Apex Limited and certain lower tier subsidiaries may be treated as passive foreign investment companies for U.S. federal income tax purposes.

        We believe that we likely were a passive foreign investment company (a "PFIC") for one or more past years including 2003, and likely will be a PFIC with respect to 2004 and potentially with respect to future years as well. If we are a PFIC, then a U.S. person who disposes or is deemed to dispose of Ordinary Shares or warrants to acquire Ordinary Shares at a gain, or who received a so-called "excess distribution" on the shares or warrants, generally would be required to treat such gain or excess distribution as ordinary income and pay an interest charge on a portion of the gain or distribution unless the taxpayer makes a timely qualified electing fund election (a "QEF" election). The PFIC rules are complex, and holders are urged to consult their own tax advisers regarding the consequences to them of us being classified as a PFIC. We do not intend to make or issue to holders of our securities determinations as to our PFIC status for any taxable years.

        As we believe that we likely were a PFIC for the 2003 tax year, U.S. persons who owned (directly or under applicable attribution rules) Ordinary Shares in 2003 should consider whether to make a QEF election with respect to 2003 for their Ordinary Shares, and for their indirect ownership in any subsidiary of ours that was a PFIC in 2003. The tax consequences of a QEF election are complex, and holders of Ordinary Shares should consult their tax advisors regarding the advisability of making this election. A QEF election for a taxable year must be made on or before the due date (as may be extended) for filing the shareholder's federal income tax return for the tax year. In order to make a QEF election, a holder of Ordinary Shares must request and obtain certain information from us. On request from a holder of Ordinary Shares, we will endeavor to furnish the information necessary to make a QEF election within ninety days after the request.

        We have in certain prior filings stated that we believed that (i) Apex Limited may be considered a PFIC but (ii) none of our non-U.S. lower tier subsidiaries was a corporation for U.S. tax purposes that would itself be considered to be a PFIC. We now believe that certain of our non-U.S. lower tier subsidiaries, including the subsidiary that contains the principal assets associated with the San Cristobal Project, were corporations for U.S. tax purposes that constituted PFICs in certain prior years. As a result, there is a possibility that some shareholders may suffer adverse U.S. federal income tax consequences that arguably might not have been suffered had they been aware of the PFIC status of these lower tier subsidiaries. Such shareholders may, however, be able to make retroactive elections in some cases that would mitigate any such adverse consequences. Moreover, under applicable proposed regulations, the fact that our lower tier subsidiaries of any consequence may not have had earnings and profits for any taxable year since formation may arguably eliminate any such tax consequences in respect of prior taxable years. For the current and all subsequent taxable years, we believe that the potential for our lower tier subsidiaries to be classified as PFICs with respect to new investors can be substantially eliminated without adverse tax consequences.

        In the future, holders of our shares may claim that they have suffered adverse tax consequences for which they could have taken remedial action if they had been aware that such subsidiaries constituted PFICs. It is not possible for us to determine the number of shareholders, if any, that might make such a claim or to determine the merits or impact of such claims on us and whether such claims may be material to us.

METALS MARKET OVERVIEW

Silver Market

        Silver has traditionally served as a medium of exchange, much like gold. Silver's strength, malleability, ductility, thermal and electrical conductivity, sensitivity to light and ability to endure extreme changes in temperature combine to make silver a widely used industrial metal. While silver continues to be used as a form of investment and a financial asset, the principal uses of silver are industrial, primarily in electrical and electronic components, photography, jewelry, silverware, batteries, computer chips, electrical contacts, and high technology printing. Silver's anti-bacterial properties also make it valuable for use in medicine

17

and in water purification. Additionally, new uses of silver are being developed in connection with the use of superconductive wire.

        Most silver production is obtained from mining operations in which silver is not the principal or primary product. Approximately 80% of mined silver is produced as a by-product of mining lead, zinc, gold, nickel or copper deposits. The CPM Group estimates that total silver supply from mine production, recycling, estimated dishoarding and government stockpile sales has been insufficient to meet industrial demand since 1990, and that stockpiles are continuing to diminish.

        The following table sets forth for the periods indicated the Comex nearby active silver futures contract's high and low price of silver in U.S. dollars per troy ounce. On March 5, 2004 the closing price of silver was $6.99 per troy ounce.

	Silver
Year
	High	Low
1999	5.77	4.86
2000	5.57	4.62
2001	4.83	4.03
2002	5.13	4.22
2003	5.99	4.35

Zinc and Lead Markets

        We expect production from San Cristobal to include the extraction, processing and sale of significant quantities of zinc and lead contained in sulfide concentrates. Our future projects may also involve the production of economically significant quantities of metals other than silver.

        Due to the corrosion resisting property of zinc, zinc is used primarily as the coating in galvanized steel. Galvanized steel is widely used in construction of infrastructure, housing and office buildings. In the automotive industry, zinc is used for galvanizing and die-casting, and in the vulcanization of tires. Smaller quantities of various forms of zinc are used in the chemical and pharmaceutical industries, including fertilizers, food supplements and cosmetics, and in specialty electronic applications such as satellite receivers.

        The primary use of lead is in motor vehicle batteries, but it is also used in cable sheathing, shot for ammunition and alloying. Lead in chemical form is used in alloys, glass and plastics. Lead is widely recycled, with secondary production accounting in recent years for approximately 50% to 52% of total supply.

        The following table sets forth for the periods indicated the London Metals Exchange's high and low settlement prices of zinc and lead in U.S. dollars per pound. On March 5, 2004 the closing prices of zinc and lead were $0.51 and $0.39 per pound, respectively.

	Zinc		Lead

ITEM 7: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

General

        The following discussion and analysis should be read together with the consolidated financial statements of Apex Silver Mines Limited and the selected financial data and related notes thereto included elsewhere in this report on form 10-K.

        Apex Limited is a mining exploration and development company that holds a portfolio of silver exploration and development properties primarily in South America, Mexico, Central America and Central Asia. We currently focus our resources primarily on the development and financing of our San Cristobal Project in Bolivia. At present, none of our properties is in production and, consequently, we have no current operating income or cash flow.

        We completed an initial public offering of our Ordinary Shares on December 1, 1997. We completed a subsequent offering of Ordinary Shares and warrants during November 1999. During January and February 2004 we completed additional subsequent offerings totaling 10.4 million Ordinary Shares resulting in gross proceeds of $218.4 million and net proceeds of $208.6 million after commissions and fees. The 2004 offerings were completed at an average offering price of $21.01 per share and substantially completed the sale of securities available under our shelf registrations filed with the Securities and Exchange Commission.

Overview

        During the first half of 2003, metals prices and capital market conditions remained at levels that we deemed unattractive for the development of San Cristobal. As a result, we kept exploration and administrative costs at levels below those of the previous two years. Interest income fell from the level earned in 2002, because capital market interest rates fell. Trading income improved, mainly due to the effect of higher metals prices on the small amount of silver and zinc that we had bought.

        As metals prices rose late in 2003 and into the early part of 2004, we found the market conditions improving and as a result, were able to successfully complete the above-noted equity offerings in early 2004. During 2004, we anticipate working with our lead arranger for project financing, Barclays Capital, and other financial organizations to advance the financing for San Cristobal. During 2004, we anticipate completing most of the remaining engineering required to develop San Cristobal.

Results of Operations

        Interest and Other Income.    Our interest and other income for the year ended December 31, 2003 was $0.5 million compared to $0.9 million and $2.2 million for the years ended December 31, 2002 and 2001, respectively. The 2003 decrease in interest and other income compared to 2002 is primarily the result of lower interest rates during 2003. The decrease in interest and other income for 2002 compared to 2001 was due to lower average cash balances and lower interest rates during 2002 as compared to 2001.

        Trading Gains and Losses.    We recorded a trading gain for the year ended 2003 of approximately $0.7 million compared to trading losses of approximately $0.1 million for 2002 and $1.0 million for 2001. The improvement in 2003 as compared to 2002 is primarily the result of rising silver and zinc prices, and to a lesser extent, rising lead prices during 2003. The improvement in 2002 of a $0.1 million loss as compared to the $1.0 million loss in 2001 is primarily the result of a smaller deterioration in the value of our long position in zinc during 2002. Inception to date, we have recorded a gain of approximately $0.2 million related to the trading program. That amount represents approximately $0.6 million of cash gains partially offset by $0.4 million of unrealized losses at December 31, 2003. Under FAS 133, fair value measurements may vary substantially from period to period based on spot prices, forward prices and quoted option volatilities.

27

        Exploration.    Our exploration expenses, including property holding costs and allocated administrative expenses, were $2.7 million for the year ended December 31, 2003, including $0.3 million value of Ordinary Shares issued to consultants, as compared to $3.9 million, including $0.9 million value of Ordinary Shares issued to acquire mineral rights, for the year ended December 31, 2002, and $3.7 million, including $0.9 million value of Ordinary Shares issued to acquire mineral rights for the year ended December 31, 2001. The decreases in our exploration expenses since 2001 were due primarily to the increased emphasis on conserving our cash balances.

        Administrative.    Our administrative expenses were $4.6 million for the year ended December 31, 2003 compared to $5.5 million and $5.9 million for the years ended December 31, 2002 and 2001, respectively. The decrease in our administrative expenses since 2001 is primarily the result of cost savings associated with the reduction of personnel and office facilities as part of our cash conserving policy. In addition, the 2003, 2002 and 2001 expenses include $1.8 million, $1.9 million and $0.5 million respectively, for the value of stock, options and warrants issued to consultants in lieu of cash.

        Income Taxes.    Apex Silver Mines Corporation, our U.S. management services company, is subject to U.S. income taxes. Otherwise we pay no income tax in the U.S. since we are incorporated in the Cayman Islands and do not conduct or expect to conduct business in the U.S. that would generate U.S. taxable income. The Cayman Islands currently impose no corporate taxation. We have been granted an exemption until January 16, 2015 from any form of corporate taxation that may subsequently be adopted in the Cayman Islands. Deferred tax assets of approximately $49.9 million at December 31, 2003, resulting from operating loss carry-forwards of our subsidiaries, have been entirely offset by valuation allowances.

Liquidity and Capital Resources

        As of December 31, 2003, we had cash and cash equivalents of $40.9 million compared to $44.1 million at December 31, 2002. The decrease in our cash and cash equivalents during 2003 is the result of $3.9 million capitalized to property, plant and equipment related to the development of the San Cristobal Project, $3.2 million used to fund operations, property holding costs and administrative costs, net of interest and other income, partially offset by $3.9 million in proceeds from the exercise of our stock options by certain employees, consultants and a former director.

        Pursuant to two universal shelf registration statements filed with the Securities and Exchange Commission, we sold 10.4 million Ordinary Shares during January and February 2004. The sales resulted in gross proceeds of $218.4 million and net proceeds of $208.6 million after commissions and fees. The offerings were completed at a weighted average offering price of $21.01 per share and the offerings substantially complete the sale of the securities available under these registration statements. Proceeds from the offerings will be used to finance a portion of the construction and development of San Cristobal, advance evaluation of exploration properties and for general corporate purposes.

        If metals and capital markets remain at levels that will allow us to do so, we intend to substantially complete the financing requirements for our San Cristobal project in the next twelve months. We continue to work with our lead arranger for project financing, Barclays Capital, as well as several multilateral agencies, to develop financing options for San Cristobal as part of a total financing package that may incorporate support from other official agencies as well as debt financing from banks and the use of capital markets. We have spent approximately $33 million on construction costs through December 31, 2003 and have expended approximately $98 million in total project capital on San Cristobal to date. Based on estimated revisions made during 2000 to the September 1999 feasibility study for the San Cristobal project, which assumes contract mining, we forecast remaining capital costs for construction to total approximately $435 million net of approximately $60 million in expected tax credits, including approximately $25 million which will be recovered against our future Bolivian income taxes after commencement of production. We expect to complete detailed engineering during 2004 and incorporate into our feasibility study any changes deriving from our ultimate infrastructure arrangements, which may result in increases to our forecasted

28

construction capital and working capital requirements. There can be no assurance that metals or capital markets will maintain their recently improved state or that we will be able to obtain the required remaining financing on terms that we find attractive, or at all.

        During the next twelve months we expect to spend up to $25 million on infrastructure development, engineering and other costs related to our San Cristobal project. In addition, in order to maintain our current portfolio of mineral properties, we expect to make lease, patent and option payments during the next twelve months of about $1 million. There also is likely to be some discretionary spending on attractive exploration opportunities as they arise. Total administrative expenses are not expected to exceed $8 million during 2004, net of interest and other income. We plan to fund our project and operating expenditures for the next twelve months from our existing cash balances.

Off Balance Sheet Arrangements

        We have no off balance sheet arrangements.

Table of Contractual Obligations

        The following table summarizes our contractual obligations at December 31, 2003:

Contractual Obligations	Total		Less Than 1 - Year		2 - 3 Years		4 - 5 Years		Thereafter
	(thousands)
Debt	$	690	$	91	$	599	$	—	$	—
Capital Leases		—		—		—		—		—
Operating Leases		607		211		396		—		—
Purchase Obligations		—		—		—		—		—
Other GAAP Liabilities		—		—		—		—		—

        From time to time we enter into lease option agreements related to exploration properties that are of interest to us. These agreements normally contain escalating lease payments required to maintain our exploration rights to the property. Such agreements are not included in the above table because exploration success is historically low and the agreements can be terminated by us at any time.

Environmental Compliance

        Our current and future exploration and development activities, as well as our future mining and processing operations, are subject to various federal, state and local laws and regulations in the countries in which we conduct our activities. These laws and regulations govern the protection of the environment, prospecting, development, production, taxes, labor standards, occupational health, mine safety, toxic substances and other matters. We expect to be able to comply with those laws and does not believe that compliance will have a material adverse effect on our competitive position. We intend to obtain all licenses and permits required by all applicable regulatory agencies in connection with our mining operations and exploration activities. We intend to maintain standards of environmental compliance consistent with best contemporary industry practice.

Critical Accounting Policies

        The selection and application of accounting policies is an important process that has developed as our business activities have evolved and as the accounting rules have changed. Accounting rules generally do not involve a selection among alternatives, but involve an implementation and interpretation of existing rules, and the use of judgment, to the specific set of circumstances existing in our business. We comply with all applicable rules on or before their adoption, and we believe the proper implementation and consistent application of the accounting rules is critical. Our critical accounting policies are discussed below. You

should also read Note 2 of the accompanying Notes to the Consolidated Financial Statements included in Item 8 of this Form 10-K.

        Our financial condition and results of operations as reflected in our financial statements are affected by estimates that we, or experts that we have retained, have made as to our proven and probable reserves. Reserve estimates involve subjective judgment and are based on numerous assumptions that may later prove to be inaccurate. These estimates include engineering evaluations of assay values derived from samplings of drill holes and other openings. Additionally, changes in the market prices of metals may render certain reserves containing relatively lower grades of mineralization uneconomic to mine. Further, availability of permits, changes in operating and capital costs, and other factors could materially and adversely affect ore reserves. Our current proven and probable reserve estimates at San Cristobal, total approximately 211 million tonnes of ore grading 65.81 grams per tonne of silver, 1.63% zinc and 0.61% lead. These reserves contain approximately 446 million ounces of silver, 7.6 billion pounds of zinc and 2.8 billion pounds of lead. The reserves are based on $4.62 per ounce silver, $0.38 per pound zinc and $0.22 per pound lead. These prices represent the three year average prices for each of the metals as per guidelines established by the Securities and exchange Commission.

        To complete the project financing on San Cristobal, we may be required to hedge a portion of our planned production. In addition, when San Cristobal enters production, we may sell forward a portion of our production and use price-hedging techniques to mitigate some of the risks associated with fluctuating metals prices. We currently engage in limited metals trading activities utilizing puts and calls and other market instruments in anticipation of potential lender requirements for the San Cristobal project financing. We measure the fair value of open positions at each reporting period and record the difference in the carrying value to current earnings, in accordance with Statement of Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities ("FAS 133"). Under FAS 133, fair value measurements may vary substantially from period to period based on spot prices, forward prices and quoted option volatilities.

ITEM 7A: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        Currently, our major principal cash balances are held in U.S. dollars. We maintain minimum cash balances in foreign currencies and therefore have a relative low exposure to currency fluctuations. Because we conduct our activities in several foreign countries, we may in the future engage in hedging activities to minimize the risk of exposure to currency and interest rate fluctuations.

        To complete the project financing for San Cristobal, we expect to be required to hedge a portion of our planned production. In addition, when San Cristobal enters production, we may sell forward a portion of our production and use price hedging techniques to mitigate some of the risks associated with fluctuating metals prices. We currently engage in limited metals trading activities, utilizing puts and calls and other market instruments in anticipation of potential lender requirements for the San Cristobal project financing. See "Results of Operations."

ITEM 9A: CONTROLS AND PROCEDURES

        Our management carried out an evaluation, under the supervision and with the participation of our principal executive officer and principal financial officer, of the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this report. Based on this evaluation, the principal executive officer and principal financial officer have concluded that our disclosure controls and procedures are effective as of December 31, 2003.

        During the quarter ended December 31, 2003, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to affect, our internal control over financial reporting.

        While we believe our internal controls are adequate and that there are no material weaknesses, it should be noted that our disclosure controls and procedures and our internal controls will not necessarily prevent all error or fraud, and can thus not provide absolute assurance that all control issues or fraud can be detected.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Shareholders of Apex Silver Mines Limited

        In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, changes in shareholders' equity and cash flows present fairly, in all material respects, the financial position of Apex Silver Mines Limited and its subsidiaries (a development stage enterprise) at December 31, 2003 and December 31, 2002, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2003 and, cumulatively, for the period from December 22, 1994 (date of inception) to December 31, 2003 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

APEX SILVER MINES LIMITED
An Exploration and Development Stage Company

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(Expressed in United States dollars)

1. Incorporation, Recapitalization, Initial Public Offering, Subsequent Offerings, Ownership and Operations

        a.     Apex Silver Mines Limited ("Apex Limited" or the "Company") was formed under the laws of the Cayman Islands in March 1996 for the sole purpose of serving as a holding company for certain ownership interests in Apex Silver Mines LDC ("Apex LDC"). On April 15, 1996, holders of approximately 55% of the then-outstanding shares of Apex LDC elected to participate, effective as of the completion of a proposed private placement of shares of Apex Limited which was completed as of August 6, 1996, in a recapitalization effected by an exchange, on a one-for-one basis, of their shares in Apex LDC for identical equity instruments of Apex Limited (the "Recapitalization"). The balance of shareholders retained a direct ownership interest in Apex LDC. As a result of this recapitalization, Apex LDC became a majority-owned subsidiary of Apex Limited. The accompanying financial statements reflect the historical accounts of the Company's predecessor, Apex LDC. For purposes of the accompanying consolidated financial statements of Apex Limited, the recapitalization has been given retroactive effect to the date of incorporation of Apex LDC, with the results of operations and equity attributable to the other ownership interests in Apex LDC being reflected in "minority interest in consolidated subsidiary". Consequently, for purposes of these financial statements, Apex Limited is considered the successor to Apex LDC.

        b.     In August 1996, Apex Limited issued 4,256,700 Ordinary Shares at $8 per share in a private placement transaction (the "Private Placement") for net proceeds of approximately $32.4 million. These proceeds were contributed to Apex LDC in exchange for the issuance by Apex LDC of 4,256,700 shares of its share capital. As a result of this private placement, the Company's ownership interest in Apex LDC was increased from approximately 55% to 65%.

        c.     On December 1, 1997, the Company closed its initial public offering (the "Offering") of Ordinary Shares. The Company sold 5,000,000 Ordinary Shares at a price of $11 per share on the American Stock Exchange under the symbol "SIL". In addition, on December 23, 1997, the underwriters exercised an option to purchase an additional 523,372 Ordinary Shares at the initial price of $11 per share. Net proceeds raised in the Offering were approximately $54.8 million. These proceeds were contributed to Apex LDC in exchange for the issuance by Apex LDC of 5,523,372 shares of its capital.

        d.     In conjunction with the Recapitalization and the Private Placement, Apex Limited and the shareholders of Apex LDC entered into a Buy-Sell Agreement which was intended to maintain the same beneficial interest in Apex LDC attributable to all shareholders of Apex LDC prior to the Recapitalization and Private Placement. During 1998, Pursuant to the terms of the Buy-Sell Agreement, Apex Limited exchanged 7,079,006 of its Ordinary Shares for an equal number of Apex LDC shares. Such shares are included in the 36,874,640 Ordinary Shares outstanding at December 31, 2003 At December 31, 2003 Apex Limited owned 100 percent of Apex LDC. Per the provisions of the Buy-Sell Agreement, all of the outstanding shares of Apex LDC are considered Ordinary Shares outstanding for the purposes of computing net loss per Ordinary Share for the periods presented.

        e.     In November 1999, pursuant to a shelf registration statement filed with the Securities and Exchange Commission, the Company sold 8,090,132 Ordinary Share units, resulting in proceeds before commissions and fees of approximately $97.1 million and net proceeds of approximately $94.1 million. The Ordinary Share units, priced at $12.00 per unit, were comprised of one Ordinary Share and a warrant which was exercisable for one-half of an Ordinary Share at a price of $18.00 per ordinary share. All of the warrants expired on November 4, 2002 and none of the warrants was exercised.

F-8

        f.      During April 2002, the Company sold 500,000 of its Ordinary Shares, pursuant to a universal shelf registration statement. The sale resulted in gross proceeds of approximately $6.6 million and expenses of approximately $0.1 million, which were paid in the form of a stock grant.

        g.     The Company's principal activities are the exploration and development of mineral properties. The Company participates in the acquisition and exploration of mineral properties for possible future development directly and indirectly through its subsidiaries.

        h.     The Company, through indirect subsidiaries, conducts exploration activities in Mexico, Central America and South America and currently holds interests in non-producing silver resource properties in Bolivia, Mexico and Peru. The Company is in the process of developing its San Cristobal property and evaluating certain of its other properties to determine the economic feasibility of bringing one or more of the properties into production.

2. Summary of Significant Accounting Policies

        These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. The policies adopted, considered by management to be significant, are summarized as follows:

        a.    Basis of consolidation

        These consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries.

        b.    Translation of foreign currencies

        Substantially all expenditures are made in United States dollars. Accordingly, the Company uses the United States dollar as its functional currency.

        c.    Cash, cash equivalents and short-term investments

        The Company considers all highly-liquid investments with a maturity of three months or less when purchased to be cash equivalents. Short-term investments include certificates of deposit with maturities greater than three months, but not exceeding twelve months. Short-term investments are recorded at cost which approximates fair value.

        d.    Mining properties, exploration and development costs

        The Company expenses general prospecting costs and the costs of acquiring and exploring unevaluated mining properties. When a mineral property is determined to have proven and probable reserves, development costs are capitalized to mineral properties. When proven and probable ore reserves are developed and operations commence, capitalized costs will be amortized using the units-of-production method over proven and probable reserves. Upon abandonment or sale of projects, all capital costs relating to the specific project are written off in the period abandoned or sold and a gain or loss is recognized. Beginning September 1, 1997, all costs associated with the Company's San Cristobal Project have been capitalized. As of December 31, 2003, capitalized property and development costs related to the San Cristobal Project amounted to $95,041,161. No other amounts related to mineral properties have been capitalized.

F-9

        e.    Property, plant and equipment

        Mineral properties include costs to acquire development properties and property development costs. Mineral properties brought into production will be charged to operations using the units-of-production method based on estimated recoverable proven and probable reserves. Buildings are stated at cost and are depreciated using the straight-line method, over useful lives of thirty to forty years. Mining equipment and machinery are stated at cost and are depreciated using the straight-line method over useful lives of three to eight years. Other furniture and equipment are stated at cost and are depreciated using the straight-line method over estimated useful lives of three to five years.

        f.    Asset impairment

        The Company evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amount may not be recoverable. If the sum of estimated future net cash flows on an undiscounted basis is less than the carrying amount of the related asset grouping, an asset impairment is considered to exist. The related impairment loss is measured by comparing estimated future net cash flows on a discounted basis to the carrying amount of the asset. Changes in significant assumptions underlying future cash flow estimates may have a material effect on the Company's financial position and results of operations. To date no such impairments have been identified.

        g.    Stock compensation

        At December 31, 2003, the Company has a stock-based employee compensation plan, which is described more fully in Note 8. The Company accounts for this plan under the recognition and measurement principles of APB Opinion No. 25, "Accounting for Stock Issued to Employees", and related interpretations. No stock-based employee compensation cost is reflected in net income, as all options granted under those plans had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation ("FAS 123"), to stock-based employee compensation:

		Year ended December 31, 2003			Year ended December 31, 2002			Year ended December 31, 2001
Net loss, as reported		$	(6,043,912	)	$	(8,654,089	)	$	(8,583,569	)
Less: Total stock based compensation expense determined under fair value based method for all awards, net of tax effect			(2,828,410	)		(2,614,014	)		(888,481	)
Pro forma net loss		$	(8,872,322	)	$	(11,268,103	)	$	(9,472,050	)
Net loss per Ordinary Share:
	Basic and diluted—as reported	$	(0.17	)	$	(.24	)	$	(.25	)
	Basic and diluted—pro forma	$	(0.24	)	$	(.32	)	$	(.27	)

        For purposes of calculating the fair value of options, volatility for the three years presented is based on the historical volatility of the Company's stock over its public trading life. The Company currently does

F-10

not foresee the payment of dividends in the near term. The fair value for these options was estimated at the date of grant using the Black-Scholes option-pricing model with the following assumptions:

	Year ended December 31, 2003		Year ended December 31, 2002		Year ended December 31, 2001
Weighted average risk-free interest rate	2.50	%	3.10	%	4.08	%
Volatility	42.80	%	42.50	%	40.60	%
Expected dividend yield	—		—		—
Weighted average expected life (in years)	2.93		2.91		2.88

        h.    Net loss per Ordinary Share

        Basic earnings per share excludes dilution and is computed by dividing net earnings available to ordinary shareholders by the weighted average number of shares outstanding for the period. Diluted earnings per share reflect the potential dilution that would occur if securities or other contracts to issue Ordinary Shares were exercised or converted into Ordinary Shares.

        Outstanding options to purchase 2,119,425, 1,963,891and 1,895,150 Ordinary Shares were not included in the computation of diluted earnings per share at December 31, 2003, 2002, and 2001 respectively, because to do so would have been antidilutive. Also, warrants to purchase 100,000 Ordinary Shares were not included in the computation of diluted earnings per share at December 31, 2003, because to do so would have been antidilutive.

        i.    Derivative financial instruments

        In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement of Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities ("FAS 133"). FAS 133, as amended by Statement of Accounting Standards No. 137, Deferral of the Effective Date of FAS Statement No. 133, became effective for the Company January 1, 2001. FAS 133 requires that all derivative instruments be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. For fair-value hedge transactions in which the Company is hedging changes in the fair value of an asset, liability, or firm commitment, changes in the fair value of the derivative instrument will generally be offset by changes in the hedged item's fair value. For cash flow hedge transactions, in which the Company is hedging the variability of cash flows related to a variable-rate asset, liability or forecasted transaction, changes in the fair value of the derivative instrument will be reported in other comprehensive income. The gains and losses on the derivative instrument that are reported in other comprehensive income will be reclassified as earnings in the periods in which earnings are impacted by the variability of cash flows of the hedged item. The ineffective portion of all hedges will be recognized in current-period earnings.

        To complete the project financing on San Cristobal, the Company may be required to hedge a portion of its planned production. In addition, when San Cristobal enters production, the Company may sell forward a portion of its production and use price-hedging techniques to mitigate some of the risks associated with fluctuating metals prices. The Company currently engages in limited metals trading activities utilizing puts and calls and other market instruments in anticipation of potential lender requirements for the San Cristobal project financing. The Company measures the fair value of open positions at each reporting period during 2003, and records the difference in the carrying value to current earnings, in accordance with FAS 133. Adoption of FAS 133 had no effect on the Company's results of operations or

F-11

financial position as previously the Company had marked its open positions to market and included gains or losses in earnings. During 2003, 2002 and 2001 the Company recorded mark to market gains (losses) of approximately $728,000, ($71,000) and ($972,000) respectively. Inception to date the Company has recorded a gain of approximately $216,000 related to the trading program. Of that amount, approximately $560,000 represents a cash gain partially offset by $344,000 of unrealized losses in value at December 31, 2003. Under FAS 133, fair value measurements may vary substantially from period to period based on spot prices, forward prices and quoted option volatilities.

        j.    New Accounting Standards

        Effective January 1, 2003, the Company adopted Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations("FAS 143") which established a uniform methodology for accounting for estimated reclamation and abandonment costs. Adoption of the standard had no current impact on the Company's earnings or financial position. See note 10.

        In April 2002, the FASB issued Statement of Financial Accounting Standards No. 145, Rescission of FAS Statements No. 4, 44 and 64, Amendment of FAS Statement No. 13, and Technical Corrections ("FAS 145"), which is generally effective for transactions occurring after May 15, 2002. Through the rescission of FAS Statements 4 and 64, FAS 145 eliminates the requirement that gains and losses from extinguishment of debt be aggregated and, if material, be classified as an extraordinary item net of any income tax effect. FAS 145 made several other technical corrections to existing pronouncements that may change accounting practice. The Company has adopted FAS 145 which did not have an impact on its results of operations or financial position at the time of adoption and is not expected to have a material impact in the future.

        In June 2002, the FASB issued Financial Accounting Standards No. 146, Accounting for Costs Associated with Exit or Disposal Activities ("FAS 146"). FAS 146 is effective for exit or disposal activities that are initiated after December 31, 2002. This Statement addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." The Company has adopted FAS 146 which did not have an impact on its results of operations or financial position at the time of adoption and is not expected to have a material impact in the future.

        In December 2002, the Financial Accounting Standards Board issued Financial Accounting Standards No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure ("SFAS No. 148"). SFAS No. 148, amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to require prominent disclosures about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. As the Company accounts for stock-based employee compensation using the intrinsic value method in accordance with APB No. 25, Accounting for Stock Issued to Employees, the Company has adopted the disclosure requirements of SFAS No. 148, effective December 31, 2002.

        In April 2003, the FASB issued SFAS No. 149 "Amendment of Statement 133 on Derivative Instruments and Hedging Activities" ("SFAS 149") to amend and clarify financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities. The changes in this statement improve financial reporting by requiring that contracts

F-12

with comparable characteristics be accounted for similarly to achieve more consistent reporting of contracts as either derivative or hybrid instruments. SFAS 149 is effective for contracts entered into or modified after June 30, 2003. SFAS 149 did not have any impact on the Company's financial position or results of operations at December 31, 2003, or for the year then ended. SFAS 149 is not expected to have any impact on the Company's financial position or results of operations.

        In May 2003, the FASB issued SFAS No. 150 "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity" ("SFAS 150") providing guidance regarding classification of freestanding financial instruments as liabilities (or assets in some circumstances). This SFAS was originally effective for financial instruments entered into or modified after May 31, 2003, otherwise at the beginning of the first interim period beginning after June 15, 2003 and was to be applied prospectively. However, on October 29, 2003, the FASB decided to defer the provisions of paragraphs 9 and 10 of SFAS 150 as they apply to mandatorily redeemable non-controlling interests. These provisions require that mandatorily redeemable minority interests within the scope of SFAS 150 be classified as a liability on the parent company's financial statements in certain situations, including when a finite-lived entity is consolidated. The deferral of those provisions is expected to remain in effect while these interests are addressed in either Phase II of the FASB's Liabilities and Equity Project or Phase II of the FASB's Business Combinations Project. The Board also decided to (i) preclude any "early" adoption of the provisions of paragraph 9 and 10 for these non-controlling interests during the deferral period, and (ii) require the restatement of any financial statements that have been issued where these provisions were applied to mandatorily redeemable non-controlling interests. SFAS 150 is not expected to have any impact on the Company's financial position or results of operations.

        In November 2002, the Financial Accounting Standards Board issued Interpretation No. 45, Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others ("FIN No. 45"). FIN No. 45 broadens the disclosures to be made by the guarantor about its obligations under certain guarantees. FIN No. 45 also requires a guarantor to recognize a liability for the fair value of the obligation undertaken in issuing the guarantee at the inception of a guarantee. The recognition provision of FIN No. 45 is applicable on a prospective basis for guarantees that are issued or modified after December 31, 2002. As required by FIN No. 45, the Company has adopted the disclosure requirements effective December 31, 2002. The Company has adopted FIN No. 45 which did not have an impact on its results of operations or financial position at the time of adoption and is not expected to have a material impact in the future.

        In January 2003, the FASB issued Interpretation No. 46, Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51 ("FIN No. 46"), which provides guidance on the identification and reporting for entities over which control is achieved through means other than voting rights. FIN 46 defines such entities as variable interest entities (VIEs). A FASB Staff Position issued in October 2003 deferred the effective date of FIN 46 to the first interim or annual period ending after December 15, 2003 for entities created before February 1, 2003 if certain criteria are met. Subsequently, during December 2003, the FASB issued a revised Fin 46 (FIN 46R) which replaces the original interpretation. Application of this revised interpretation is required in financial statements for companies that have interests in VIEs or potential VIEs commonly referred to as special-purpose entities for periods ending after December 15, 2003. Application for all other types of entities is required in financial statements for periods ending after March 15, 2004. The Company is currently evaluating the impact FIN 46R will have on its financial statements. Based on current assessments the Company does not beleive that FIN 46 will have impact on results of operations, financial position or cash flow.

F-13

3. Income Taxes

        The provision for income taxes includes United States federal, state and foreign income taxes currently payable and deferred based on currently enacted tax laws. Deferred income taxes are provided for the tax consequences of differences between the financial statement and tax bases of assets and liabilities. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax asset may not be realized.

        There is currently no taxation imposed by the Cayman Islands. If any form of taxation were to be enacted, the Company has been granted exemption therefrom to January 16, 2015. The Company's subsidiaries which do business in other countries have not generated income and therefore are not liable for local income taxes.

        As of December 31, 2003 and 2002, operating loss carryforwards generated by our activities in Bolivia amounted to approximately $20.0 and $18.6 million, respectively. Operating losses (as adjusted for inflation) may be carried forward and deducted from taxable income indefinitely. The deferred tax asset resulting from the operating loss carryforwards has been entirely offset by a valuation allowance.

        As of December 31, 2003 and 2002, operating loss carryforwards generated by the Company's subsidiaries other than Bolivia amounted to approximately $29.9 and $28.3 million, respectively. The deferred tax assets resulting from these operating loss carryforwards have been entirely offset by valuation allowances.

4. Prepaid Expenses and Other Assets

        Prepaid expense and other assets consist of the following:

	December 31, 2003		December 31, 2002
Prepaid insurance	$	487,677	$	505,861
Prepaid consulting & contractor fees		1,317,442		—
Trade receivables, travel advances and other		361,883		28,374
	$	2,167,002	$	534,235

        The prepaid consulting and contractor fees at December 31, 2003, consist primarily of the value of stock issued to two contractors to provide exploration services related to certain of the Company's properties in Bolivia, Peru and Uzbekistan, which will be completed in 2004. Included in trade receivables, travel advances and other at December 31, 2003, is the $225,641 value of stock options exercised in late December 2003, for which the cash had not been received.

5. Value Added Tax Recoverable

        The Company has recorded value added tax ("VAT") paid in Bolivia and Mexico as recoverable assets. Bolivian law states that VAT paid prior to production is recoverable as a credit against Bolivian taxes arising from production, including income tax. The VAT paid in Bolivia is expected to be recovered through production from the proven and probable reserves at the San Cristobal Project that the Company intends to develop. The VAT paid in Mexico is related to exploration activities and according to Mexican law is recoverable upon application to the tax authorities. Although the Company has filed applications to recover all VAT paid through the third quarter of 2002, the Mexican tax authorities have not refunded any

F-14

VAT to the Company since early 2000. The Company has been informed that the Mexican tax authorities, for their own fiscal reasons, have made no VAT refunds to any companies since early 2000. Based on these circumstances, the Company recorded a 50% impairment of the recoverable VAT in Mexico, although it remains the Company's intent to recover the full amount. At December 31, 2003, the recoverable VAT recorded for Bolivia and Mexico is $5,056,095 and $182,553 respectively after the impairment.

        Because of the uncertainty of the recoverability of VAT paid in Peru, VAT costs incurred in Peru are charged to expense as incurred.

6. Property, Plant and Equipment

8. Stock Option Plans

        The Company has established a plan to issue share options and other awards to be valued by reference to the Company's shares for officers, employees, consultants and agents of the Company and its subsidiaries (the "Plan"). Under the Plan, the total number of options and other awards granted cannot exceed ten percent of the Company's outstanding shares. Options granted and other awards under the Plan are non-assignable. Options exist for a term, not to exceed ten years, as fixed by the Compensation Committee of the Board of Directors of the Company. Options vest ratably over periods of up to four years with the first tranche vesting on the date of grant or the anniversary of the date of grant. Unexercised options expire ten years after the date of grant.

        The Company has established a share option plan for its non-employee directors (the "Director Plan"). Under the Director Plan, the total number of options granted cannot exceed five percent of the Company's outstanding shares. Pursuant to the Director Plan, non-employee directors receive (i) at the effective date of their initial election to the Company's board of directors, an option to purchase the number of Ordinary Shares equal to $50,000 divided by the closing price of the Ordinary Shares on the American Stock Exchange (the "AMEX") on such date, (ii) at the close of business of each annual meeting of the Company's shareholders, an option to purchase the number of Ordinary Shares equal to $50,000 divided by the closing price of the Ordinary Shares on the AMEX on such date, and (iii) at the close of business of each meeting of the Company's Board of Directors, an option valued at $3,000 calculated using the Black-Scholes option-pricing model to purchase Ordinary Shares with an exercise price equal to the closing price of the Ordinary Shares on the AMEX on such date. Options granted to a non-employee director vest on the date of the grant and expire ten years after the date of the grant or one year after the date that such non-employee director ceases to be a director of the Company. Options granted under the Director Plan are transferable only in limited circumstances.

10. Asset Retirement Obligations

12. Fair Value of Financial Instruments

        The Company's financial instruments consist of cash and cash equivalents, receivables, value added tax recoverable, accounts payable, other current liabilities and long-term debt. Except for the value added tax and long-term debt, the carrying amounts of these financial instruments approximate fair value due to their short maturities. The estimated fair values of the Company's long-term financial instruments, as measured on December 31, 2002 and 2001, are as follows:

	2003				2002
	Carrying Amount		Fair Value		Carrying Amount		Fair Value

Notes payable		689,958		540,649		769,958		629,621

        The fair values of the value added tax recoverable and the long-term debt are estimated based on the expected timing of future cash flows.

13. Segment Information

        In 1998, the Company adopted Statement of Accounting Standards No. 131, Disclosure about Segments of an Enterprise and Related Information. The Company's sole activity is exploration for and development of silver properties and, consequently substantially all of the Company's long-lived assets are in Bolivia.

APEX SILVER MINES LIMITED
Warrant to Purchase Ordinary Shares

                        Ordinary Shares

        THIS CERTIFIES that, for good and valuable consideration received,                        (the "Holder"), is entitled to subscribe for and purchase from APEX SILVER MINES LIMITED a corporation incorporated under the laws of the Cayman Islands (the "Company"), upon the terms and conditions set forth herein, at any time or from time to time after July 29, 2004 until 5:00 P.M. New York City time on January 27, 2009 (the "Exercise Period"), all or any portion of 72,000 Ordinary Shares of the Company, par value $0.01 per share, subject to adjustment as provided herein (the "Warrant Shares"), at a price of $20.79 per share, subject to adjustment as provided herein (the "Exercise Price"). This Warrant shall not be redeemable by the Company. The term "Shares" as used herein shall mean the Company's Ordinary Shares, par value $0.01 per share. This Warrant has been issued pursuant to the Placement Agency Agreement, dated January 27, 2004, between the Company and Sunrise Securities Corp. (the "Agency Agreement"). This Warrant may not be sold, transferred, assigned or hypothecated by the Holder or any Permitted Transferee (as hereinafter defined) until July 29, 2004, except that it may be assigned, in whole or in part, to (i) one or more officers or partners of the Holder (or the officers or partners of any such partner); (ii) a successor to the Holder, or the officers or partners of such successor; (iii) a purchaser of substantially all of the assets of the Holder; or (iv) by operation of law (each a "Permitted Transferee") and the term the "Holder" as used herein shall include any Permitted Transferee to whom this Warrant has been transferred in accordance with the above.

        1.    Method of Exercise.    This Warrant may be exercised at any time during the Exercise Period, as to the whole or any lesser number of Warrant Shares, by the surrender of this Warrant (with the election at the end hereof duly executed) to the Company at its office at 1700 Lincoln St, Suite 3050, Denver, CO, 80203, or at such other place as may be designated in writing by the Company, together with a certified or bank cashier's check payable to the order of the Company in an amount equal to the Exercise Price multiplied by the number of Warrant Shares for which this Warrant is being exercised.

        2.    Issuance of Certificates.    Upon each exercise of the Holder's rights to purchase Warrant Shares, the Holder shall, as of the close of business on such day, be deemed to be the holder of record of the Warrant Shares issuable upon such exercise, notwithstanding that the transfer books of the Company shall then be closed or certificates representing such Warrant Shares shall not then have been actually delivered to the Holder. As soon as practicable after each such exercise of this Warrant, the Company shall issue and deliver to the Holder a certificate or certificates for the Warrant Shares issuable upon such exercise, registered in the name of the Holder or its designee. If this Warrant should be exercised in part only, upon surrender of this Warrant for cancellation, the Company shall execute and deliver a new Warrant evidencing the right of the Holder to purchase the balance of the Warrant Shares (or portions thereof) subject to purchase hereunder.

        3.    Recording of Transfer.    Any warrants issued upon the transfer or exercise in part of this Warrant shall be numbered and shall be registered in a Warrant Register as they are issued. The Company shall be entitled to treat the registered holder of any Warrant on the Warrant Register as the

2

owner in fact thereof for all purposes and shall not be bound to recognize any equitable or other claim to or interest in such Warrant on the part of any other person, and shall not be liable for any registration or transfer of warrants which are registered or to be registered in the name of a fiduciary or the nominee of a fiduciary unless made with the actual knowledge that a fiduciary or nominee is committing a breach of trust in requesting such registration or transfer, or with the knowledge of such facts that its participation therein amounts to bad faith. This Warrant shall be transferable only on the books of the Company upon delivery thereof duly endorsed by the Holder or by his or its duly authorized attorney or representative, or accompanied by proper evidence of succession, assignment or authority to transfer. In all cases of transfer by an attorney, executor, administrator, guardian or other legal representative, duly authenticated evidence of his or its authority shall be produced. Upon any registration of transfer, the Company shall deliver a new warrant or warrants to the person entitled thereto. This Warrant may be exchanged, at the option of the Holder hereof, for another warrant, or other warrants of different denominations, of like tenor and representing in the aggregate the right to purchase a like number of Warrant Shares (or portions thereof), upon surrender to the Company or its duly authorized agent. Notwithstanding the foregoing, the Company shall have no obligation to cause this Warrant to be transferred on its books to any person if counsel to the Company reasonably requests a legal opinion that such transfer does not violate the provisions of the Securities Act of 1933, as amended (the "Act"), and the rules and regulations thereunder, unless such opinion is delivered.

        4.    Reservation of Shares.    The Company shall at all times reserve and keep available out of its authorized and unissued Shares, solely for the purpose of providing for the exercise of the warrants, such number of shares of Shares as shall, from time to time, be sufficient therefor. The Company covenants that all shares of Shares issuable upon exercise of this Warrant, upon receipt by the Company of the full payment therefor, shall be validly issued, fully paid, nonassessable and free of preemptive rights.

        5.    Exercise Price Adjustments.    Subject to the provisions of this Section 5, the Exercise Price in effect from time to time shall be subject to adjustment, as follows:

        (a)   In case the Company shall at any time after the date hereof (i) declare a dividend or make a distribution, including a spin-off, on the outstanding Shares payable in shares of its capital stock or securities convertible into or exchangeable for capital stock, (ii) subdivide the outstanding Shares, (iii) combine the outstanding Shares into a smaller number of shares, or (iv) issue any shares by reclassification of the Shares (other than a change in par value, or from par value to no par value, or from no par value to par value), then, in each case, the Exercise Price in effect, and the number of Shares issuable upon exercise of the warrants outstanding, at the time of the record date for such dividend or at the effective date of such subdivision, combination or reclassification, shall be proportionately adjusted so that the holders of the warrants after such time shall be entitled to receive upon exercise of the warrant the aggregate number and kind of shares which, if such warrants had been exercised immediately prior to such time, such holders would have owned upon such exercise and immediately thereafter been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. Such adjustment shall be made successively whenever any event listed above shall occur.

        (b)   In the event that the Company shall during the two (2) year period following the issuance of this Warrant and prior to the exercise of all Warrants declare a dividend (other than a dividend consisting solely of shares of Common Stock) or otherwise spin-off or distribute to its stockholders any assets, property or securities (other than shares of Common Stock), representing any of the Company's exploration and/or production properties, the Holders of the unexercised Warrants shall thereafter be entitled, in addition to the Shares or other securities and property receivable under the exercise thereof, to receive, upon the exercise of such Warrants, the same property, assets or securities representing any of the Company's exploration and/or production properties that they would have been entitled to receive at the time of such dividend or distribution as if the Warrants

3

had been exercised immediately prior to such dividend or distribution. At the time of any such dividend or distribution, the Company shall make appropriate reserves to ensure the timely performance of the provisions of this Subsection 5(b).

        (c)   Whenever there shall be an adjustment as provided in this Section 5, the Company shall within 15 days thereafter cause written notice thereof to be sent by registered mail, postage prepaid, to the Holder, at its address as it shall appear in the Warrant Register, which notice shall be accompanied by an officer's certificate setting forth the number of Warrant Shares issuable hereunder and the exercise price thereof after such adjustment and setting forth a brief statement of the facts requiring such adjustment and the computation thereof, which officer's certificate shall be conclusive evidence of the correctness of any such adjustment absent manifest error.

        (d)   The Company shall not be required to issue fractions of Shares or other shares of the Company upon the exercise of this Warrant. If any fraction of a share would be issuable upon the exercise of this Warrant (or specified portions thereof), the Company may issue a whole share in lieu of such fraction or the Company may purchase such fraction for an amount in cash equal to the same fraction of the Current Market Price of such Shares on the date of exercise of this Warrant.

        (e)   The Current Market Price per Share on any date shall be deemed to be the average of the daily closing prices for the five (5) consecutive trading days immediately preceding the date in question. The closing price for each day shall be the last reported sales price regular way or, in case no such reported sale takes place on such day, the closing bid price regular way, in either case on the American Stock Exchange or any other principal national securities exchange on which the Ordinary Shares are listed or admitted to trading or, if the Ordinary Shares are not listed or admitted to trading on any national securities exchange, the highest reported bid price for the Ordinary Shares as furnished by the National Association of Securities Dealers, Inc. through NASDAQ or a similar organization if NASDAQ is no longer reporting such information. If on any such date the Ordinary Shares are not listed or admitted to trading on any national securities exchange and is not quoted by NASDAQ or any similar organization, the fair value of a share of the Ordinary Shares on such date, as determined in good faith by the Board of Directors of the Company, whose determination shall be conclusive absent manifest error, shall be used.

        (f)    No adjustment in the Exercise Price shall be required if such adjustment is less than $0.01; provided, however, that any adjustments which by reason of this Section 5 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 5 shall be made to the nearest cent or to the nearest thousandth of a share, as the case may be.

        (g)   Upon each adjustment of the Exercise Price as a result of the calculations made in this Section 5, the warrants shall thereafter evidence the right to purchase, at the adjusted Exercise Price, that number of Shares (calculated to the nearest hundredth) obtained by dividing (i) the product obtained by multiplying the number of Shares purchasable upon exercise of the warrants prior to adjustment of the number of Shares by the Exercise Price in effect prior to adjustment of the Exercise Price by (ii) the Exercise Price in effect after such adjustment of the Exercise Price.

        6.    Consolidations and Mergers.

        (a)   In case of any consolidation with or merger of the Company with or into another corporation (other than a merger or consolidation in which the Company is the surviving or continuing corporation and which does not result in any reclassification of the outstanding Shares or the conversion of such outstanding Shares into shares of other stock or other securities or property), or in case of any sale, lease or conveyance to another corporation of the property and assets of any nature of the Company as an entirety or substantially as an entirety (such actions

4

being hereinafter collectively referred to as "Reorganizations"), there shall thereafter be deliverable upon exercise of this Warrant (in lieu of the number of Shares theretofore deliverable) the kind and amount of shares of stock or other securities, cash or other property which would otherwise have been deliverable to a holder of the number of Shares upon the exercise of this Warrant upon such Reorganization if this Warrant had been exercised in full immediately prior to such Reorganization. In case of any Reorganization, appropriate adjustment, as determined in good faith by the Board of Directors of the Company, shall be made in the application of the provisions herein set forth with respect to the rights and interests of the Holder so that the provisions set forth herein shall thereafter be applicable, as nearly as possible, in relation to any shares or other property thereafter deliverable upon exercise of this Warrant. The Company shall not effect any such Reorganization unless upon or prior to the consummation thereof the successor corporation, or if the Company shall be the surviving corporation in any such Reorganization and is not the issuer of the shares of stock or other securities or property to be delivered to holders of Shares outstanding at the effective time thereof, then such issuer, shall assume by written instrument the obligation to deliver to the Holder such shares of stock, securities, cash or other property as the Holder shall be entitled to purchase in accordance with the foregoing provisions.

        (b)   In case of any reclassification or change of the Shares issuable upon exercise of this Warrant (other than a change in par value or from no par value to a specified par value, or as a result of a subdivision or combination, but including any change in the shares into two or more classes or series of shares), or in case of any consolidation or merger of another corporation into the Company in which the Company is the continuing corporation and in which there is a reclassification or change (including a change to the right to receive cash or other property) of the Shares (other than a change in par value, or from no par value to a specified par value, or as a result of a subdivision or combination, but including any change in the shares into two or more classes or series of shares), the Holder shall have the right thereafter to receive upon exercise of this Warrant solely the kind and amount of shares of stock and other securities, property, cash or any combination thereof receivable upon such reclassification or change by a holder of the number of Shares for which this Warrant might have been exercised immediately prior to such reclassification or change. Thereafter, appropriate provision shall be made for adjustments which shall be as nearly equivalent as practicable to the adjustments in Section 5.

        (c)   The above provisions of this Section 6 shall similarly apply to successive reclassifications and changes of Shares and to successive consolidations, mergers, sales, leases, or conveyances.

        7.    Notice of Certain Events.    In case at any time any of the following occur:

        (a)   The Company shall take a record of the holders of its Shares for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of current or retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company; or

        (b)   The Company shall offer to all the holders of its Shares any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor; or

        (c)   The Company shall take any action to effect any reclassification or change of outstanding Shares or any consolidation, merger, sale, lease or conveyance of property, described in Section 6; or

        (d)   The Company shall take any action to effect any liquidation, dissolution or winding-up of the Company or a sale of all or substantially all of its property, assets and business;

then, and in any one or more of such cases, the Company shall give written notice thereof, by registered mail, postage prepaid, to the Holder at the Holder's address as it shall appear in the

5

Warrant Register, mailed at least fifteen (15) days prior to (i) the date as of which the holders of record of Shares to be entitled to receive any such dividend, distribution, rights, warrants or other securities are to be determined, (ii) the date on which any such offer to holders of Shares is made, or (iii) the date on which any such reclassification, change of outstanding Shares, consolidation, merger, sale, lease, conveyance of property, liquidation, dissolution or winding-up is expected to become effective and the date as of which it is expected that holders of record of Shares shall be entitled to exchange their shares for securities or other property, if any, deliverable upon such reclassification, change of outstanding shares, consolidation, merger, sale, lease, conveyance of property, liquidation, dissolution or winding-up. Nothing herein shall allow a Holder to delay or prevent any of the foregoing actions.

        8.    Registration Rights.

        (a)   If, on any two occasions during the five-year period commencing on the date hereof, the Company shall receive a written request from Eligible Holders who in the aggregate own (or upon exercise of all Warrants then outstanding would own) a majority of the total number of shares of the Ordinary Shares then included (or upon such exercises would be included) in the Warrant Shares (the "Majority Holders"), to register the sale of all or part of the Warrant Shares, the Company shall, as promptly as practicable, prepare and file with the Securities and Exchange Commission (the "Commission") a registration statement sufficient to permit the public offering and sale of the Warrant Shares (whether covered by such request from the Majority Holders or by any other written request from any Eligible Holder received within 30 days after such Eligible Holder's receipt of the Company's notice, as described in the last sentence of this Section 8(a)) through the facilities of all appropriate securities exchanges and the over-the-counter market, and will use its reasonable best efforts through its officers, directors, auditors, and counsel to cause such registration statement to become effective as promptly as practicable; provided, that the Company shall only be obligated to file one such registration statement for which all expenses incurred in connection with such registration (other than the fees and disbursements of counsel for the Eligible Holders and underwriting discounts, if any, payable in respect of the Warrant Shares sold by the Eligible Holders) shall be borne by the Company. Within five business days after receiving any request contemplated by this Section 8(a), the Company shall give written notice to all the other Eligible Holders, advising each of them that the Company is proceeding with such registration and offering to include therein all or any portion of any such other Eligible Holder's Warrant Shares, provided that the Company receives a written request to do so from such Eligible Holder within 30 days after receipt by him or it of the Company's notice. All references to "Warrants" and "Warrant Shares" in this Section 8 shall mean all of the warrants (including this Warrant) to purchase Ordinary Shares issued in connection with the Agency Agreement. Under no circumstances shall the Company be required to effectuate more than two demand registrations in the aggregate pursuant to this Warrant and any other warrants issued pursuant to the Agency Agreement.

        (b)   In the event of a registration pursuant to the provisions of this Section 8, the Company shall use its commercially reasonable efforts to cause the Warrant Shares so registered to be registered or qualified for sale under the securities or blue sky laws of such jurisdictions as the Holder or such holders may reasonably request; provided, however, that the Company shall not be required to qualify to do business in any state by reason of this Section 8(b) in which it is not otherwise required to qualify to do business or otherwise subject itself to general service of process in any such state.

        (c)   The Company shall keep effective any registration or qualification contemplated by this Section 8(a) and shall from time to time amend or supplement each applicable registration statement, preliminary prospectus, prospectus, application, document and communication for such period of time as shall be required to permit the Eligible Holders to complete the offer and sale of

6

the Warrant Shares covered thereby. The Company shall in no event be required to keep any such registration or qualification in effect for a period in excess of six months from the date on which the Eligible Holders are first free to sell such Warrant Shares; provided, however, that, if the Company is required to keep any such registration or qualification in effect with respect to securities other than the Warrant Shares beyond such period, the Company shall keep such registration or qualification in effect as it relates to the Warrant Shares for so long as such registration or qualification remains or is required to remain in effect in respect of such other securities.

        (d)   In the event of a registration pursuant to the provisions of this Section 8, the Company shall furnish to each Eligible Holder such number of copies of the registration statement and of each amendment and supplement thereto (in each case, including all exhibits), such reasonable number of copies of each prospectus contained in such registration statement and each supplement or amendment thereto (including each preliminary prospectus), all of which shall conform to the requirements of the Act and the rules and regulations thereunder, and such other documents, as any Eligible Holder may reasonably request to facilitate the disposition of the Warrant Shares included in such registration.

        (e)   In the event of a registration pursuant to the provisions of this Section 8, the Company shall furnish each Eligible Holder of any Warrant Shares so registered with an opinion of its counsel (reasonably acceptable to the Eligible Holders) to the effect that (i) the registration statement has become effective under the Act and no order suspending the effectiveness of the registration statement, preventing or suspending the use of the registration statement, any preliminary prospectus, any prospectus or any amendment or supplement thereto has been issued, nor has the Commission or any securities or blue sky authority of any jurisdiction instituted or threatened to institute any proceedings with respect to such an order, (ii) the registration statement and each prospectus forming a part thereof (including each preliminary prospectus), and any amendment or supplement thereto, complies as to form with the Act and the rules and regulations thereunder, and (iii) such counsel has no knowledge of any material misstatement or omission in such registration statement or any prospectus, as amended or supplemented.

        (f)    In the event of a registration pursuant to the provision of this Section 8, the Company shall enter into a cross-indemnity agreement and a contribution agreement, each in customary form, with each underwriter, if any, and, if requested, enter into an underwriting agreement containing conventional representations, warranties, allocation of expenses and customary closing conditions, including, without limitation, opinions of counsel and accountants' cold comfort letters, with any underwriter who acquires any Warrant Shares.

        (g)   The Company agrees that until all the Warrant Shares have been sold under a registration statement or pursuant to Rule 144 under the Act, it shall, so long as it is so required by applicable law, timely file all reports, statements and other materials required to be filed with the Commission to permit holders of the Warrant Shares to sell such securities under Rule 144, for a period of up to five years from the date hereof.

        (h)   The Company may delay any requested registration hereunder if the Company's Board of Directors determines in good faith that a registration at such time would be materially detrimental to the Company provided that any such delay shall not exceed 30 days and Company cannot provide this notice more than twice in any 12 month period.

        (i)    Subject to the conditions set forth below, the Company agrees to indemnify and hold harmless each Eligible Holder, its officers, directors, partners, employees, agents and counsel, and each person, if any, who controls any such person within the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), from and against any and all loss, liability, charge, claim, damage and expense whatsoever (which shall

7

include, for all purposes of this Section 8, without limitation, reasonable attorneys' fees and any and all expense whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), as and when incurred, arising out of, based upon, or in connection with (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any registration statement, preliminary prospectus or prospectus (as from time to time amended and supplemented), or any amendment or supplement thereto, relating to the sale of any of the Warrant Shares, or (B) in any application or other document or communication (in this Section 8 collectively called an "application") executed by or on behalf of the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to register or qualify any of the Warrant Shares under the securities or blue sky laws thereof or filed with the Commission or any securities exchange; or any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, unless such statement or omission was made in reliance upon and in conformity with written information furnished to the Company with respect to such Eligible Holder by or on behalf of such person expressly for inclusion in any registration statement, preliminary prospectus, or prospectus, or any amendment or supplement thereto, or in any application, as the case may be, or (ii) any breach of any representation, warranty, covenant or agreement of the Company contained in this Warrant. The foregoing agreement to indemnify shall be in addition to any liability the Company may otherwise have, including liabilities arising under this Warrant. If any action is brought against any Eligible Holder or any of its officers, directors, partners, employees, agents or counsel, or any controlling persons of such person (an "indemnified party") in respect of which indemnity may be sought against the Company pursuant to the foregoing paragraph, such indemnified party or parties shall promptly notify the Company in writing of the institution of such action (but the failure so to notify shall not relieve the Company from any liability other than pursuant to this Section 8(i) and shall not relieve the Company from any liability pursuant to this Section 8(i) except to the extent the Company has been prejudiced in any material respect by such failure) and the Company shall promptly assume the defense of such action, including the employment of counsel (reasonably satisfactory to such indemnified party or parties) and payment of expenses. Such indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless the employment of such counsel shall have been authorized in writing by the Company in connection with the defense of such action or the Company shall not have promptly employed counsel reasonably satisfactory to such indemnified party or parties to have charge of the defense of such action or such indemnified party or parties shall have reasonably concluded that there may be one or more legal defenses available to it or them or to other indemnified parties which are different from or additional to those available to the Company, in any of which events such fees and expenses of one counsel shall be borne by the Company, and the Company shall not have the right to direct the defense of such action on behalf of the indemnified party or parties. Anything in this Section 8 to the contrary notwithstanding, the Company shall not be liable for any settlement of any such claim or action effected without its written consent, which shall not be unreasonably withheld. The Company shall not, without the prior written consent (which shall not be unreasonably withheld) of each indemnified party that is not released as described in this sentence, settle or compromise any action, or permit a default or consent to the entry of judgment in or otherwise seek to terminate any pending or threatened action, in respect of which indemnity may be sought hereunder (whether or not any indemnified party is a party thereto), unless such settlement, compromise, consent or termination includes an unconditional release of each indemnified party from all liability in respect of such action. The Company agrees promptly to notify the Eligible Holders of the commencement of any litigation or proceedings against the Company or any of its officers or directors in connection with the sale of

8

any Warrant Shares or any preliminary prospectus, prospectus, registration statement or amendment or supplement thereto, or any application relating to any sale of any Warrant Shares.

        (j)    Each of the Holder and any Eligible Holder agrees to indemnify and hold harmless the Company, each director of the Company, each officer of the Company who shall have signed any registration statement covering Warrant Shares held by the Holder and any Eligible Holder, each other person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, and its or their respective counsel, to the same extent as the foregoing indemnity from the Company to the Holder in Section 8(i), but only with respect to statements or omissions, if any, made in any registration statement or prospectus, or any amendment or supplement thereto, or in any application, in reliance upon and in conformity with written information furnished to the Company with respect to the Holder by or on behalf of the Holder or with respect to any Eligible Holder or by or on behalf of such Eligible Holder expressly for inclusion in any such registration statement or prospectus, or any amendment or supplement thereto, or in any application, as the case may be; provided, however, that the Holder and each Eligible Holder shall be liable only for written information furnished to the Company by it or on its own behalf for inclusion in a registration statement; and provided, further, that no Eligible Holder shall be liable in an amount greater than the net proceeds received by such Eligible Holder in connection with the applicable registration. If any action shall be brought against the Company or any other person so indemnified based on any such registration statement or prospectus, or any amendment or supplement thereto, or in any application, and in respect of which indemnity may be sought against the Holder pursuant to this Section 8(j), the Holder and each Eligible Holder, as the case may be, shall have the rights and duties given to the Company, and the Company and each other person so indemnified shall have the rights and duties given to the indemnified parties, by the provisions of Section 8(i).

        (k)   To provide for just and equitable contribution, if (i) an indemnified party makes a claim for indemnification pursuant to Section 8(i) or 8(j) (subject to the limitations thereof) but it is found in a final judicial determination, not subject to further appeal, that such indemnification may not be enforced in such case, even though this Agreement expressly provides for indemnification in such case, or (ii) any indemnified or indemnifying party seeks contribution under the Act, the Exchange Act or otherwise, then the Company (including for this purpose any contribution made by or on behalf of any director of the Company, any officer of the Company who signed any such registration statement, any controlling person of the Company, and its or their respective counsel), as one entity, and the Eligible Holders of the Warrant Shares included in such registration in the aggregate (including for this purpose any contribution made by or on behalf of an indemnified party), as a second entity, shall contribute to the losses, liabilities, claims, damages and expenses whatsoever to which any of them may be subject, on the basis of relevant equitable considerations such as the relative fault of the Company and such Eligible Holders in connection with the facts which resulted in such losses, liabilities, claims, damages and expenses. The relative fault, in the case of an untrue statement, alleged untrue statement, omission or alleged omission, shall be determined by, among other things, whether such statement, alleged statement, omission or alleged omission relates to information supplied by the Company or by such Eligible Holders, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement, alleged statement, omission or alleged omission. The Company and the Holder agree that it would be unjust and inequitable if the respective obligations of the Company and the Eligible Holders for contribution were determined by pro rata or per capita allocation of the aggregate losses, liabilities, claims, damages and expenses (even if the Holder and the other indemnified parties were treated as one entity for such purpose) or by any other method of allocation that does not reflect the equitable considerations referred to in this Section 8(k). In no case shall any Eligible Holder be responsible for a portion of the contribution obligation imposed on all Eligible Holders in excess of its pro rata share based on the number of shares of the

9

Ordinary Shares owned (or which would be owned upon exercise of all Warrants) by it and included in such registration as compared to the number of shares of the Ordinary Shares owned (or which would be owned upon exercise of all Warrants) by all Eligible Holders and included in such registration nor shall any Eligible Holder be responsible for an amount greater than the net proceeds received by such Eligible Holder in connection with the applicable registration. No person guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation. For purposes of this Section 8(k), each person, if any, who controls any Eligible Holder within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and each officer, director, partner, employee, agent and counsel of each such Eligible Holder or control person shall have the same rights to contribution as such Eligible Holder or control person and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each officer of the Company who shall have signed any such registration statement, each director of the Company and its or their respective counsel shall have the same rights to contribution as the Company, subject in each case to the provisions of this Section 8(k). Anything in this Section 8(k) to the contrary notwithstanding, no party shall be liable for contribution with respect to the settlement of any claim or action effected without its written consent. This Section 8(k) is intended to supersede any right to contribution under the Act, the Exchange Act or otherwise.

        (l)    In addition to the registration rights set forth in Sections 8(a) through 8(k), it is contemplated that the Warrant Shares will be included for registration in the Company's next shelf registration statement on Form S-3.

        9.    Taxes.    The issuance of any shares or other securities upon the exercise of this Warrant and the delivery of certificates or other instruments representing such shares or other securities shall be made without charge to the Holder for any tax or other charge in respect of such issuance. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Holder (except for any tax that is payable in respect of any such transfer and any related exercise of this Warrant and that would be payable pursuant to the first sentence of this Section 9 were such certificate to be issued in the name of the Holder) and the Company shall not be required to issue or deliver any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

        10.    Legend.    Unless registered pursuant to the provisions of Section 8 hereof, the certificate or certificates evidencing the Warrant Shares, shall bear the following legend:

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR STATE SECURITIES LAWS, BUT HAVE BEEN ISSUED OR TRANSFERRED PURSUANT TO AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT. NO DISTRIBUTION, SALE, OFFER FOR SALE, TRANSFER, DELIVERY, PLEDGE, OR OTHER DISPOSITION OF THESE SECURITIES MAY BE EFFECTED EXCEPT IN COMPLIANCE WITH THE ACT, ANY APPLICABLE STATE LAWS, AND THE RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION AND STATE AGENCIES PROMULGATED THEREUNDER."

        11.    Replacement of Warrants.    Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of any Warrant (and upon surrender of any Warrant if mutilated), and upon reimbursement of the Company's reasonable incidental expenses and execution of a reasonable

10

lost security indemnification agreement, the Company shall execute and deliver to the Holder thereof a new Warrant of like date, tenor and denomination.

        12.    No Rights as Stockholder.    The Holder of any Warrant shall not have, solely on account of such status, any rights of a stockholder of the Company, either at law or in equity, or to any notice of meetings of stockholders or of any other proceedings of the Company, except as provided in this Warrant.

        13.    Notices.    All notices, requests, consents and other communications hereunder shall be in writing and shall be deemed to have been duly made when delivered, or mailed by registered or certified mail, return receipt requested:

        (a)   If to the registered Holder of this Warrant, to the address of such Holder as shown on the books of the Company; or

        (b)   If to the Company, to the address set forth on the first page of this Warrant or to such other address as the Company may designate by notice to the Holder.

        14.    Successors.    All the covenants, agreements, representations and warranties contained in this Warrant shall bind the parties hereto and their respective heirs, executors, administrators, distributees, successors and assigns.

        15.    Headings.    The Article and Section headings in this Warrant are inserted for purposes of convenience only and shall have no substantive effect.

        16.    Governing Law.    This Warrant shall be construed in accordance with the laws of the State of New York applicable to contracts made and performed within such State, without regard to principles of conflicts of law.

        17.    Modification of Agreement.    This Warrant shall not otherwise be modified, supplemented or amended in any respect unless such modification, supplement or amendment is in writing and signed by the Company and the Holder of this Warrant and Holders of any portion of the Warrant subsequently assigned or transferred in accordance with the terms of this Warrant.

        18.    Consent to Jurisdiction.    The Company and the Holder irrevocably consent to the jurisdiction of the courts of the State of New York and of any federal court located in such State in connection with any action or proceeding arising out of or relating to this Warrant, any document or instrument delivered pursuant to, in connection with or simultaneously with this Warrant, or a breach of this Warrant or any such document or instrument. In any such action or proceeding, the Company waives personal service of any summons, complaint or other process and agrees that service thereof may be made in accordance with Section 13 hereof.
