RECENT DEVELOPMENTS On November 5, 1999, our company completed a public offering of 7,214,466 units, resulting in approximately $82.9 million aggregate net proceeds to our company, after deducting commissions and estimated expenses of the offering. USE OF PROCEEDS Our company expects that the net proceeds from the sale of the units offered by this prospectus supplement, after deducting commissions and estimated expenses of the offering, will be approximately $10.0 million. Our company plans to use a majority of the net proceeds to finance a portion of the construction and development of the San Cristobal project. Our company plans to finance the remaining portion of the construction and development of the San Cristobal project through external financings, which may include bank borrowings and additional debt and equity offerings. The remaining portion of the net proceeds of the offering will be used for the following purposes: . exploring and developing properties in our portfolio; . maintaining control or ownership of our properties, including making ongoing lease and royalty payments and paying other maintenance and registration fees; . acquiring additional mining related properties or businesses; and . financing other general corporate purposes. Pending the application of the net proceeds, we expect to invest the proceeds in short-term investment grade marketable securities or money market obligations. The proceeds from the exercise of the warrants offered by this prospectus supplement are expected to be applied in the same manner. The exercise price of a whole warrant for one ordinary share is initially $18.00 or 150% of the price of the ordinary shares offered by this prospectus supplement. The exercise price of the warrants may be adjusted in accordance with the terms of the warrant. See "Description of the Warrants." DESCRIPTION OF THE WARRANTS General The warrants are being issued pursuant to a warrant agreement between our company and American Stock Transfer & Trust Company, as the warrant agent. The following summary of the S-1 material provisions of the warrant agreement are not complete. You should refer to the warrant agreement, a copy of which will be filed with the SEC prior to the issuance of the units. The warrants offered by this prospectus supplement are initially exercisable for an aggregate of 449,100 ordinary shares. Each whole warrant is exercisable for one ordinary share at an exercise price of $18.00 per share. If an adjustment of the exercise price occurs, the number of ordinary shares issuable upon exercise of the warrants would increase or decrease proportionately. See "--Adjustment." The warrants will expire at 5:00 p.m., New York City time, on November 4, 2002. We have reserved and will continue to reserve out of our authorized share capital, a number of ordinary shares sufficient to provide for the issuance of ordinary shares upon the exercise of the warrants. The certificates for the warrants will be numbered and registered in a warrant register maintained by the warrant agent. The registered holder of a warrant will be treated as the owner of that warrant for all purposes. Our company will pay any documentary stamp taxes, if any, attributable to the initial issuance of any warrant certificates or certificates for ordinary shares issuable upon exercise of the warrants. However, the warrant holder shall pay any taxes that may be payable in respect of any transfer involved in the issue or delivery of any warrant certificates or certificates for ordinary shares unless that holder has paid our company the amount of the tax or has established to our satisfaction that the tax has been paid. There is no public market for the warrants and we do not expect that a market for the warrants will develop. There can be no assurance that the market price of the ordinary shares will exceed the exercise price of the warrants. Transfer of Warrants The warrants are transferable only on the books of the warrant agent upon delivery of a warrant certificate, duly endorsed by the registered holder or by an authorized representative or accompanied by proper evidence of succession, assignment or authority to transfer. Endorsements must be guaranteed by an eligible guarantor institution which is a member of a signature guarantee program satisfactory to the warrant agent. Warrants may be transferred only in whole, so as to allow the holder of each warrant to purchase one whole ordinary share. In addition, any transfer of a warrant must be in a minimum increment of one hundred warrants. Without the prior written consent of our company, during the first thirty days after the date of the warrant agreement, a warrant certificate may not be transferred or exchanged other than for the full number of unexercised warrants that the certificate represents. Exercise of Warrants Each warrant certificate initially entitles the holder of the warrant to purchase for cash the number ordinary shares indicated on the certificate at the exercise price of $18.00 per share, subject to any adjustments made pursuant to the warrant agreement. Warrants may be exercised at any time from the opening of business on November 5, 1999 to 5:00 p.m., New York City time, on November 4, 2002. After that time and date, unexercised warrants will become void. Subject to the terms of the warrant agreement, a warrant may be exercised upon: . the surrender of the warrant certificate evidencing that warrant to the warrant agent; S-2 . delivery of the subscription form duly executed, with the signature guaranteed by an eligible institution; and . delivery of payment of the exercise price by certified or official bank check. Upon receipt of the warrant certificate, the duly executed subscription form and payment of the exercise price, the warrant agent shall cause to be issued and delivered as soon as practicable the ordinary shares purchased upon exercise. No fractions of ordinary shares, cash or other consideration will be issued. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants. Adjustment An adjustment to the number of ordinary shares purchasable upon exercise of each warrant will be made if our company takes any of the following actions at any time while a warrant is outstanding: . declare a dividend or make a distribution on the ordinary shares payable in ordinary shares; . subdivide or reclassify the outstanding ordinary shares into a greater number of ordinary shares; or . combine or reclassify the outstanding ordinary shares into a smaller number of ordinary shares. If any of these events occur, then the exercise price and the number of ordinary shares to be issued upon exercise of a warrant in effect on the record date of these actions will be proportionately adjusted so that the holder of a warrant exercised after that time shall be entitled to receive the aggregate number of ordinary shares which, if the warrant had been exercised immediately before the action, the holder would have owned upon exercise and been entitled to receive by virtue of the dividend, subdivision, combination or reclassification. Notwithstanding anything to the contrary, no adjustment in the exercise price will be made unless the increase or decrease is at least 1 percent of the exercise price. Any adjustments that are not made as a result of the immediately preceding sentence will be carried forward and taken into account into any subsequent adjustment. In addition, no adjustment to the exercise price or other terms of the warrants will be made if the registered holder is to participate in any transaction on a basis, and with notice, that the board of directors of our company determines to be fair and appropriate in light of the basis and notice on which holders of ordinary shares participate in the transaction. Mergers, Consolidations and Other Transactions If (1) we consolidate into or merge or consummate an arrangement, reconstruction or statutory share exchange with, any other person or company or (2) any other person or company acquires all of our outstanding ordinary shares, each registered holder will have the right upon exercise of a warrant and payment of the exercise price, to purchase the kind and amount of shares of stock and other securities and property, including cash, that the holder would have owned or been entitled to receive after the happening of the consolidation, merger, arrangement, reconstruction or share exchange, had the warrant been exercised immediately prior to the event. No Rights as Shareholders S-3 Holders of warrants are not entitled to vote, receive dividends, consent or receive notice as shareholders with respect to any meeting of shareholders, or to exercise any rights whatsoever as shareholders. Modification of the Warrants Our company and the warrant agent may supplement or amend the warrant agreement without the approval of any holder in order to cure any ambiguity or correct or supplement any provision that may be defective or inconsistent with any other provision of the warrant agreement or as our company and the warrant agreement deems necessary or advisable, but which do not materially and adversely affect the interest of the holders. Our company and the warrant agent may also supplement or amend the warrant agreement in any other respect with the written consent of the holders of a majority of the outstanding warrants. Notwithstanding the foregoing, each holder must consent to the following events, to the extent the events are not originally provided for in the warrant agreement or made in compliance with applicable law: . a change the number or nature of securities purchasable upon the exercise of any warrant; . increase the exercise price of any warrant or . accelerate the expiration date of any warrant. CERTAIN FEDERAL INCOME TAX CONSIDERATIONS The following discussion is a summary of certain Cayman Islands and U.S. federal income tax consequences of the ownership of ordinary shares and warrants by an investor that holds the warrants and shares as capital assets. The discussion is based on the Internal Revenue Code and the tax laws of the Cayman Islands and the United States as in effect on the date of this prospectus supplement, which are subject to change. The discussion does not address all material tax consequences of the ownership of the ordinary shares and warrants, and does not consider any specific facts or circumstances that may apply to a particular investor, including tax-exempt entities, insurance companies, banks, broker-dealers, investors liable for alternative minimum tax, investors who hold ordinary shares and warrants as part of straddles or hedging or conversion transactions or constructive sales, and investors whose functional currency is not the U.S. dollar, which may be subject to special rules. In addition, the discussion does not address special rules that could, in some circumstances, apply to a U.S. Holder of ordinary shares and warrants that owns directly or by attribution 10 percent or more of the ordinary shares. Because the discussion is not exhaustive of all possible tax considerations relevant to the ownership of ordinary shares and warrants and individual circumstances may vary and because the discussion is not based upon an opinion of counsel, prospective investors are urged to consult their tax advisors regarding the U.S. federal, state, local and foreign tax consequences, including the Cayman Islands tax consequences, of the acquisition, ownership and disposition of ordinary shares and warrants in their particular circumstances. Cayman Islands Taxation There is, at present, no direct income taxation in the Cayman Islands. Accordingly, income and gains received by our company, and distributions by our company to our shareholders and gains realized S-4 upon the disposition of ordinary shares and warrants, will be received free of all Cayman Islands income and withholding taxes. Our company is registered as an exempted company under Cayman Islands law, and our company has received an undertaking from the Governor-in-Council of the Cayman Islands to the effect that, for a period of 20 years from the date of the undertaking, no law that is enacted in the Cayman Islands imposing any tax to be levied on profits or income or gains or appreciations will apply to our company nor shall any tax in the nature of estate duty or inheritance tax be payable on the shares, debentures or other obligations of our company. United States Federal Income Taxation For purposes of this discussion, a U.S. Holder is any beneficial owner that owns ordinary shares and/or warrants as capital assets and is: . a citizen or resident of the U.S., . a corporation or partnership that is created or organized in the U.S. or under the law of the U.S. or any state, . an estate that is subject to U.S. federal income tax on its income regardless of source, or . a trust, if a court within the U.S. is able to exercise primary supervision over the administration of the trust and one or more U.S. fiduciaries have authority to control all substantial decisions of the trust. U.S. Holders Ownership and Disposition of Warrants Sale of a Warrant. Generally, a U.S. Holder of a warrant will recognize gain or loss upon the sale of a warrant in an amount equal to the difference between the amount realized on the sale and the U.S. Holder's adjusted tax basis for the warrant. A U.S. Holder's adjusted tax basis in a warrant will generally equal its cost, increased by the amount of any constructive distributions to the U.S. Holder in respect of the warrants as a result of an adjustment to the conversion ratio. In order to determine the cost of a warrant, the total purchase price paid for the ordinary share/warrant units offered by this prospectus supplement must be allocated between the ordinary shares and the warrants acquired, based upon their relative fair market value. Our company will provide this information upon request to any holder. See "--Adjustments Under the Warrants," below. Gain or loss attributable to the sale of an option to buy or sell property is considered gain from the sale of property that has the same character as the property to which the option relates. The warrants relate to ordinary shares. Accordingly, subject to the discussion below regarding the passive foreign investment company status of our company, gain or losses attributable to the sale of warrants will generally constitute capital gains and losses if the ordinary shares would be a capital asset in the hands of the warrant holder and will be long term if the warrants have been held for more than one year. Exercise of a Warrant. In general, no gain or loss will be recognized by a U.S. Holder upon the exercise of a warrant. Upon the exercise of a warrant, the holder's tax basis in the shares so acquired will be the sum of (1) the holder's adjusted tax basis in the warrant and (2) the cash paid upon exercise of the warrant. A U.S. Holder's holding period in the ordinary shares so acquired will begin on the day following the date the warrants are exercised for purposes of determining whether gain on the sale of the ordinary shares will be treated as long-term or short-term capital gain. S-5 Expiration of the Warrants. Upon expiration of an unexercised warrant, the holder will recognize a loss equal to the adjusted tax basis of the warrant in the hands of the holder. The character of the loss recognized upon the failure to exercise an option is determined based on the character of the property to which the option relates. Because the warrants relate to ordinary shares, a loss recognized upon expiration of a warrant will generally be capital loss if the ordinary shares would have been a capital asset in the hands of the warrant holder and will be long term if the warrant was held for more than one year. Adjustments Under the Warrants. Pursuant to the terms of the warrants, the number of ordinary shares that may be purchase upon exercise of the warrants is subject to adjustment from time to time upon the occurrence of the events described under "Description of the Warrants--Adjustment." In some circumstances, a change in the conversion ratio or any transaction having a similar effect on the interest of a warrant holder may be treated as a distribution with respect to any warrant holder whose proportionate interest in the earnings and profits of the issuer is increased by that change or transaction. As a result, under some circumstances which may or may not occur, an adjustment pursuant to the terms of the warrants may be treated as a taxable distribution to the warrant holders to the extent of our company's current or accumulated earnings and profits, as determined for U.S. federal income tax purposes, without regard to whether the warrant holders receive any cash or other property. If the warrant holders receive a taxable distribution, their tax bases in the warrants will be increased by an amount equal to the taxable distribution. Passive Foreign Investment Company Considerations. As discussed below, our company may constitute a passive foreign investment company (PFIC) for any taxable year. If our company were treated as a PFIC during a U.S. Holder's holding period for the warrants, then such U.S. Holder will be subject to a special tax regime in respect of gains realized on the sale or other disposition of warrants. Although not entirely free from doubt, the PFIC rules should not apply to gain realized in respect of any warrants disposed of during the same taxable year in which the warrants are acquired. In general, under the PFIC rules, a U.S. Holder will be required to allocate any gain realized on the sale of the warrants to each day during the Holder's holding period for the warrants, and will be taxable at the highest rate of taxation applicable to ordinary income for the year to which the gain is allocable, without regard to the U.S. Holder's other items of income and loss for such taxable year. This deferred tax, other than the tax on amounts allocable to the year of disposition, then will be increased by an interest charge computed by reference to the rate generally applicable to underpayments of tax, which interest charge generally will be non-deductible interest expense for individual taxpayers. A U.S. Holder of warrants will not be entitled to elect to have our company treated as a "qualified electing fund" ("QEF election") or a mark to market election, as described below, to alleviate adverse tax consequences arising from the special tax regime. Holders of warrants also should note that they may be subject to adverse PFIC consequences as the result of their possible indirect ownership of certain "lower-tier PFICs," which are discussed below. The application of the PFIC rules to ordinary shares received upon an exercise of the warrants also raise complicated tax issues. The application of the PFIC rules to holders of warrants is complex. Investors are urged to consult their U.S. tax advisors with respect to the PFIC consequences of owning and exercising the warrants. A U.S. Holder who owns warrants during any year that our company is a PFIC must file an Internal Revenue Service Form 8621 in respect of such warrants and, under proposed U.S. Treasury Regulations, in respect of interests in any lower- tier PFICs. Prospective investors are urged to consult their own tax advisors regarding the possible classification of our company as a PFIC as well as the potential tax consequences arising from the ownership and disposition, directly or indirectly, of interests in a PFIC. S-6 Ownership and Disposition of Ordinary Shares Taxation of Dividends Subject to the discussion under "Passive Foreign Investment Company Considerations" and "Foreign Personal Holding Company Considerations," under U.S. federal income tax law, U.S. Holders must include in gross income as a dividend the gross amount of any distribution paid by our company to the extent of its current or accumulated earnings and profits, as determined for U.S. federal income tax purposes, as ordinary income when the dividend is received by the U.S. Holder. The dividend will not be eligible for the dividends-received deduction generally allowed to U.S. corporations. In general, the dividend will be income from sources outside the U.S., and generally will be treated together with other items of "passive income" or, in the case of certain holders, "financial services income" for U.S. foreign tax credit purposes. Taxation of Capital Gains Subject to the discussion under "Passive Foreign Investment Company Considerations," upon a sale or other disposition of ordinary shares, a U.S. Holder will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the U.S. dollar value of the amount realized and the U.S. Holder's tax basis, determined in U.S. dollars, in the ordinary shares. This gain or loss will be capital gain or loss and, if the U.S. Holder's holding period for those ordinary shares exceeds one year, will be long-term capital gain or loss. Passive Foreign Investment Company Considerations Classification as a PFIC. Our company will be a PFIC for any taxable year if 75 percent or more of its gross income for the taxable year is "passive" income or 50 percent or more of its assets produce or are held for the production of "passive" income. For purposes of applying these income and asset tests, our company is deemed to receive its pro rata share of the income, and to own its pro rata share of the assets, of any corporation in which our company directly or indirectly owns 25 percent or more of the stock, measured by value. In addition, although not free from doubt, it is expected that our company will be deemed to receive its pro rata share of the income, and to own its pro rata share of the assets, of any partnership in which our company is a partner, either directly or through one or more intervening partnerships. U.S. Holders should be aware that the ordinary shares may be treated as stock of a PFIC for U.S. federal income tax purposes because our company will earn significant passive income from investments relative to any non-passive income of our company prior to the commencement by our company of substantial mining operations. Further, the Internal Revenue Code treats gains from transactions in commodities, such as silver, as passive income for PFIC purposes unless "substantially all" of a company's business is as an active producer of the commodity. Applicable U.S. Treasury Regulations interpret "substantially all" to mean that 85 percent or more of a producer's taxable income must be gross receipts from sales in the active conduct of a commodities business or certain related activities. Under these rules, there can be no assurance that our company would not be treated as a PFIC even after it has begun to earn income from mining operations. In this regard, prospective investors should note that our company would likely constitute a PFIC even after it begins to generate significant income from mining operations in the event our company conducts its mining operations predominantly through the use of independent contractors rather than directly through the use of its own employees. Prospective investors should note that the PFIC classification rules are complex and may apply in numerous unexpected circumstances. Under these rules, our company could be classified as a PFIC in various circumstances in addition to those described in the preceding paragraphs. For example, our company could constitute a PFIC for any taxable year as a consequence of owning substantial "passive S-7 assets" such as cash and marketable securities, including any cash derived from the issuance of our company's securities or the sale of assets of our company, even in a year in which our company generates significant income from direct mining operations. Consequences of PFIC Status. If our company were treated as a PFIC for any taxable year of a U.S. Holder's holding period for its shares, unless a U.S. Holder makes a QEF election or mark to market election in respect of our company, that U.S. Holder will be subject to a special tax regime (1) in respect of gains realized on the sale or other disposition of ordinary shares, and (2) in respect of distributions on ordinary shares held for more than one taxable year to the extent those distributions constitute "excess distributions." Although not entirely free from doubt, the PFIC rules should not apply to gain realized in respect of any ordinary shares disposed of during the same taxable year in which the ordinary shares are acquired. An excess distribution generally includes dividends or other distributions received from a PFIC in any taxable year to the extent the amount of such distributions exceeds 125 percent of the average distributions for the three preceding years or, if shorter, the investor's holding period. In general, under the PFIC rules, a U.S. Holder will be required to allocate such excess distributions and any gain realized on the sale of the ordinary shares to each day during the Holder's holding period for the ordinary shares, and will be taxable at the highest rate of taxation applicable to ordinary income for the year to which the excess distribution or gain is allocable, without regard to the U.S. Holder's other items of income and loss for such taxable year. This deferred tax, other than the tax on amounts allocable to the year of disposition or receipt of the distribution, will then be increased by an interest charge computed by reference to the rate generally applicable to underpayments of tax, which interest charge generally will be non- deductible interest expense for individual taxpayers. QEF Election. The special PFIC tax rules described above will not apply to a U.S. Holder if the U.S. Holder makes a QEF election in the first taxable year of the holder's ownership of the ordinary shares during which our company is a PFIC and our company complies with specified reporting requirements. Our company intends to comply with all reporting requirements necessary for U.S. Holders to make a QEF election with respect to our company and will upon request provide to U.S. Holders the information that may be required to make a QEF election effective. A U.S. Holder that makes a QEF election with respect to our company will be currently taxable on its pro rata share of ordinary earnings and net capital gain of our company for each taxable year of our company in which our company qualifies as a PFIC, regardless of whether the holder receives any distribution from our company. The U.S. Holder's basis in the ordinary shares of our company will be increased to reflect taxed but undistributed income of our company. Distributions of income that previously has been taxed will result in a corresponding reduction of basis in the ordinary shares and will not be taxed again as a distribution to the U.S. Holder. During the period in which our company may be a PFIC, our company may be entitled to deductions under U.S. federal income tax principles that may substantially offset earnings of our company. As a result, the pro rata share of the ordinary earnings and net capital gain of our company that would be includable by a U.S. Holder making a QEF election may not be material. If this were the case, U.S. Holders generally could obtain the benefits of making a QEF election in respect of our company, including the elimination of deferred tax and interest charges on excess distributions and realized gains, without having to bear current inclusions of income substantially in excess of distributions received. U.S. Holders should consult their own tax advisors concerning the most appropriate manner in which to make a QEF election. Lower-Tier PFICs. At the present time, none of our company's non-U.S. subsidiaries is or will be classified as a corporation for U.S. federal income tax purposes. Accordingly, U.S. Holders are not subject to the PFIC rules with respect to their indirect ownership interests in these subsidiaries. S-8 If our company is a PFIC and, in the future, our company acquires a non- U.S. subsidiary that is classified as a corporation for U.S. federal income tax purposes, U.S. Holders generally would be deemed to own, and also would be subject to the PFIC rules with respect to, their indirect ownership interests in any corporate subsidiaries of our company which themselves constitute PFICs. These indirect corporate subsidiaries are referred to as "lower-tier PFICs." If our company were a PFIC and a U.S. Holder does not make a QEF election in respect of any lower-tier PFIC, the U.S. Holder could incur liability for the deferred tax and interest charge described above if either (1) our company receives a distribution from, or disposes of all or part of its interest in, a lower-tier PFIC or (2) the U.S. Holder disposes of all or part of its ordinary shares. Our company intends to cause any lower-tier PFIC to comply with all reporting requirements necessary for a U.S. Holder to make a QEF election with respect to the lower-tier PFIC. Mark to Market Election. For taxable years beginning after December 31, 1997, a U.S. Holder who owns marketable stock of a PFIC may elect to recognize any gain or loss on the stock on a mark-to-market basis at the end of the U.S. Holder's taxable year. If an election is made, any mark-to-market gains, and any gains realized on disposition of the stock, will be treated as ordinary income. Mark-to-market losses, and any losses recognized on disposition of the stock to the extent of the holder's net mark-to-market gains, will be treated as ordinary losses. U.S. Holders should consult their tax advisors regarding the effect of making a mark-to-market election with respect to the ordinary shares, including the effect of such an election on any lower-tier PFICs that the holder is deemed to own. A U.S. Holder who owns ordinary shares during any year that our company is a PFIC must file an Internal Revenue Service Form 8621 in respect of such ordinary shares and, under proposed U.S. Treasury Regulations, in respect of interests in any lower-tier PFICs. Prospective investors are urged to consult their own tax advisors regarding the possible classification of our company as a PFIC as well as the potential tax consequences arising from the ownership and disposition, directly or indirectly, of interests in a PFIC. Foreign Personal Holding Company Considerations Prospective investors should also be aware that special U.S. tax laws would apply to U.S. Holders of ordinary shares if our company, or any corporate subsidiary of our company, is characterized as a foreign personal holding company (FPHC). In particular, if our company, or any corporate subsidiary, is an FPHC in respect of any taxable year of our company, U.S. Holders may be subject to current tax on their direct or indirect pro rata share of the income of the FPHC, as determined for purposes of the FPHC rules, even if no cash dividend is actually paid by the FPHC. In general, our company, or any corporate subsidiary of our company, will constitute a FPHC during a taxable year if (1) a specified percentage of its income is passive for purposes of the FPHC rules, and (2) at any time during the taxable year five or fewer individuals who are U.S. citizens or residents own directly, indirectly or constructively more than 50 percent of the voting power or value of such company's stock. Our company does not anticipate that it or any of its subsidiaries will be an FPHC immediately following this offering or in the future. Our company, however, can provide no assurance as to this conclusion. Non-U.S. Holders An investor who is not a U.S. Holder will not be subject to U.S. federal income tax on any dividends received on the ordinary shares unless (1) the investor has an office or other fixed place of business in the U.S. to which the dividends are attributable and either the dividends are derived in the active conduct of a banking, finance or similar business in the United States or the investor is a non-U.S. corporation the principal business of which consists of trading in stocks or securities for its own account S-9 and other specified conditions are met or (2) the investor is a foreign insurance company that conducts business in the U.S. and the dividends are attributable to that business. An investor who is not a U.S. Holder will not be subject to U.S. federal income tax on any gain realized on the sale or other disposition of ordinary shares or warrants unless (1) the investor is engaged in the conduct of a trade or business in the Unties States and the gain is effectively connected with that trade or business or (2) the investor is an individual who is present in the United States for 183 days or more during the taxable year in which the gain is realized and other specified conditions are met. United States Information Reporting and Backup Withholding Under current U.S. federal income tax law, payments of dividends to some U.S. Holders are subject to information reporting, and a "back up" withholding tax at a rate of 31 percent if these persons fail to supply correct taxpayer identification numbers and other information in the required manner. Payments of dividends to a U.S. Holder (1) made by mail or wire transfer to an address in the United States, (2) made by a paying agent, broker or other intermediary in the United States or (3) made by a U.S. broker or by a custodian, nominee or agent that is (a) a U.S. person, (b) a controlled foreign corporation for U.S. tax purposes, or (c) a foreign person 50% or more of whose gross income is from a U.S. trade or business (the persons described in (a), (b) and (c) shall be referred to as a "U.S. Controlled Person") to that holder outside the United States may be subject to U.S. information reporting requirements. Payments of dividends received by investors who are not U.S. Holders generally would be exempt from these reporting requirements, but these persons may be required to comply with certification and identification procedures in order to prove their exemption from the reporting requirements. Treasury regulations currently in effect do not require backup withholding with respect to dividends paid by a foreign corporation such as our company. The payment of proceeds of the disposition of ordinary shares or warrants by a holder to or through the U.S. office of a broker generally will be subject to information reporting and backup withholding at a rate of 31 percent, unless the holder either certifies its status as a non-U.S. Holder under penalties of perjury or otherwise establishes an exemption. The payment of proceeds of the disposition by a holder of ordinary shares or warrants to or through a non-U.S. office of a broker will generally not be subject to backup withholding and information reporting. However, information reporting, but not backup withholding, may apply to such a holder who sells a beneficial interest in ordinary shares or warrants through a non U.S. branch of a U.S. broker, or through a non-U.S. office of a U.S. Controlled Person, in either case, unless the holder establishes an exemption or the broker has documentary evidence in its files of the holder's status as a non-U.S. person. Any amounts withheld under the backup withholding rules from payment to a holder will be refunded, or credited against the holder's U.S. federal income tax liability, if any, provided that the required information is furnished to the U.S. Internal Revenue Service.

To understand the terms of our securities, you should carefully read this document with the attached prospectus supplement. Together these documents will give the specific terms of the securities we are offering. You should also read the documents to which we have referred you in "Where You Can Find More Information" below for information on our company and our financial statements. The Company Apex Silver Mines Limited explores and develops silver properties in South America and Central America. We have one of the largest, most diversified portfolios of privately owned and controlled silver exploration properties in the world. Our exploration efforts have produced our first development project, the San Cristobal project located in southern Bolivia. None of our properties are in production, and, consequently, we have no current operating income or cash flow. We maintain our principal executive offices at Caledonian House, Jennett Street, George Town, Grand Cayman, Cayman Islands, British West Indies. Our telephone number is (345) 949-0050. The Securities We May Offer This prospectus is part of a registration statement (File No. 333-76181) that we filed with the Securities and Exchange Commission utilizing a "shelf" registration process. Under this shelf registration process, we may offer from time to time any of the following securities, either separately or in units: . debt securities; . preference shares; . depositary shares; . ordinary shares; . warrants; and . ordinary share purchase rights. This prospectus provides you with a general description of the securities which we may offer. Each time we offer securities, we will provide you with a prospectus supplement that will describe the specific amounts, prices and terms of the securities being offered. The prospectus supplement may also add, update or change information contained in this prospectus. The securities which we may offer may involve a high degree of risk. A prospectus supplement relating to any security that we offer will describe the risks relating to each offered security. In addition, a prospectus supplement may also contain additional risk factors relating to our business. Debt Securities We may offer general obligations of our company, which may be senior or subordinated. The senior debt securities will have the same ranking as all of our other unsecured, unsubordinated debt. The subordinated debt securities will be entitled to payment only after payment on our senior indebtedness. In addition, we are a holding company that conducts all of our operations through subsidiaries. As a result, claims of the holders of the debt securities will generally have a junior position to claims of creditors of our subsidiaries and preferred shareholders of our subsidiaries, except to the extent that our company is recognized as a creditor of those subsidiaries. The senior debt securities will be issued under an indenture between our company and Wilmington Trust Company, as trustee for the senior debt securities. The subordinated debt securities will be issued under an indenture between our company and Wilmington Trust FSB, as trustee for the subordinated debt securities. We have summarized the material features of the debt securities that will be included in the indentures. We encourage you to read the form of the indentures and our recent periodic and current reports that we file with the SEC. The indentures are included as exhibits to this registration statement. Directions on how you can get copies of these reports are provided under "Where You Can Find More Information" below. General Indenture Provisions that Apply to Senior Debt Securities and Subordinated Debt Securities . Neither form of indenture limits the amount of debt securities that we may issue under that indenture. . If we comply with the requirements of the indentures, we may merge or consolidate with another company, or sell all or substantially all of our assets to another company. If these events occur, the other company will be required to assume our responsibilities relating to the debt securities, and we will be released from all liabilities and obligations. There is no restriction on other companies merging into our company. . Generally, the indentures provide that holders of a majority of the total principal amount of outstanding debt securities of all series affected by a proposed change to specified obligations may vote to change our obligations or your rights concerning the debt securities of those series. For this purpose, the holders of debt securities of all series will vote as a class. However, to change the amount or timing of principal, interest or other payments under a series of debt securities, every holder in that series must consent. Events of Default Each indenture provides that each of the following is an event of default: . If we do not pay interest for 30 days after its due date. . If we do not pay principal or premium when due. . If we do not make any sinking fund payment for 30 days after its due date. . If we continue to breach a covenant for 90 days after notice. . If a bankruptcy or insolvency event set forth in the indenture occurs. If an event of default occurs with respect to any series of debt securities, the trustee or holders of 25% of the outstanding principal amount of that series may declare the principal amount of that series immediately payable or, in the case of a bankruptcy or insolvency event, the principal amount of all series under the indenture immediately payable. However, holders of a majority of the principal amount may rescind this action. 2 General Indenture Provisions that Apply Only to Senior Debt Securities The prospectus supplement relating to a series of senior debt securities will describe any material covenants or any special events of default in respect of that series of senior debt securities. General Indenture Provisions that Apply Only to Subordinated Debt Securities The subordinated debt securities will be subordinated to all senior indebtedness, which includes all indebtedness for money borrowed by our company, except indebtedness that is stated to be not superior to, or to have the same ranking as, the subordinated debt securities. In addition, claims of our subsidiaries' creditors and preferred shareholders generally will have priority with respect to the subsidiaries' assets and earnings over the claims of our creditors, including holders of the subordinated debt securities, even though those obligations may not constitute senior indebtedness. The subordinated debt securities, therefore, will be effectively subordinated to creditors, including trade creditors, and preferred shareholders of our subsidiaries with regard to the assets of those subsidiaries. The prospectus supplement relating to a series of subordinated debt securities will describe any material covenants or special events of default in respect of that series of subordinated debt securities. Preference Shares and Depositary Shares We may issue our preference shares, par value $0.01 per share, in one or more classes or series. Our Board of Directors will determine for the preference shares, the dividend, voting, redemption, sinking fund, conversion, liquidation preference, relative priority and other rights of the class or series being offered and the terms and conditions relating to its offering and sale at the time of the offer and sale. We may also issue fractional shares of preference shares that will be represented by depositary shares and depositary receipts. Ordinary Shares We may issue our ordinary shares, par value $0.01 per share. Holders of ordinary shares are entitled to receive dividends when declared by the Board of Directors. The right to receive dividends is also subject to the rights of holders of preference shares. Each holder of ordinary shares is entitled to one vote per share. The holders of ordinary shares have no preemptive rights or cumulative voting rights. Warrants We may issue warrants for the purchase of preference shares or ordinary shares. We may issue warrants independently or together with other securities. A prospectus supplement relating to the warrants will describe the terms of the warrants, including the following: . the title, number and offering price of the warrants; . the terms on which they may be issued; and . the number, designation and description of the ordinary shares or preference shares that may be purchased upon exercise of the warrants and the price at which the shares may be purchased. 3 Ordinary Share Purchase Rights We may issue rights to purchase ordinary shares. We may issue ordinary share purchase rights independently or together with other securities. Our Board of Directors will determine for the ordinary share purchase rights, the number, the exercise price, the terms on which they may be issued, the extent of transferability, the date of commencement and the date of expiration. RISK FACTORS Prospective purchasers of our securities should consider carefully, in addition to the other information contained in, or incorporated by reference into, this prospectus or any prospectus supplement, the following risk factors: No Production History - we have not mined any silver or other metals. Our company has 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. History of Losses - 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, 1998, we had an accumulated deficit of $39.8 million. There can be no assurance that we will achieve or sustain profitability in the future. Potential Inaccuracy of the Reserves and Other Mineralization Estimates 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 and/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 for these properties 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. 4 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. San Cristobal Project Risks - the completion of the San Cristobal project is subject to delays in commencement and completion, our inability to achieve anticipated production volume and cost increases. We plan to complete the development of the San Cristobal project and commence production operations by late 2001. However, there can be no assurance that: . the development of the San Cristobal project will be commenced or completed on a timely basis, if at all; . the resulting operations will achieve the anticipated production volume; or . the construction costs and ongoing operating costs associated with the development of the San Cristobal project will not be higher than anticipated. If the actual cost to complete the development of the San Cristobal project is significantly higher than 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. Failure to obtain necessary project financing on acceptable terms, to commence or complete the development of the San Cristobal project on a timely basis, to achieve anticipated production capacity, and unexpected cost increases could have a material adverse effect on our future results of operations and financial condition. The successful development of the San Cristobal project is subject to the other risk factors described in this prospectus. Dependence on a Single Mining Project - our principal asset is the San Cristobal project. We anticipate that the majority, if not all, of our revenues and profits 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 in a timely manner, our ability to generate revenue and profits would be materially adversely affected. Management of Growth - our success will depend on our ability to manage our growth. We anticipate that as we bring our mineral properties 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 increase demands on our operating and financial systems. There can be no assurance that we will successfully meet these demands and manage our anticipated growth. Volatility of Metals Prices - 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: 5 . 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. The aggregate effect of these factors on metals prices is impossible for our company to predict. A decrease in metals prices could 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. The following table sets forth (1) the London Silver Market's high and low spot price of silver in U.S. dollars per troy ounce and (2) the London Metals Exchange's high and low spot prices of zinc and lead in U.S. dollars per pound, for the periods indicated. Silver Zinc Lead ------------------------------- ---------------------------- ----------------------------- Year High Low High Low High Low - ---- ------------- ---------------- -------------- -------------- ------------- --------------- 1994.................... 5.75 4.64 0.54 0.41 0.31 0.15 1995.................... 6.04 4.41 0.55 0.43 0.35 0.24 1996.................... 5.83 4.71 0.50 0.44 0.42 0.30 1997.................... 6.27 4.22 0.60 0.47 0.33 0.23 1998.................... 6.83 4.88 0.52 0.42 0.27 0.22 Hedging and Currency Risks - we may not be successful in hedging against price, currency and interest rate fluctuations and may lose money through our hedging programs. We have commenced a limited preliminary program to hedge against commodity and base metals price 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. 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. 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. 6 Uncertainty and Cost of Mineral Exploration and Acquisition - 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. See "--Competition." 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 . construct, renovate or expand mining and processing facilities. If we discover mineralization, 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, that our exploration programs will result in new proven and probable reserves in sufficient quantities to justify commercial operations in any of our company's 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. Development Risks - 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. See "--Volatility of 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 7 . 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. See "--San Cristobal Project Risks." 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 facilities; . 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 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. 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 or impugned. 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. Property Rights - 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. 8 Mining Risks and Limits of Insurance Coverage - 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; . cave-ins; 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 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. Foreign Operations - we conduct all of our exploration activities 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, Chile, Honduras, 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; 9 . 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. 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 controls; . income and other taxes; . maintenance of claims; . environmental legislation; . foreign ownership restrictions; . 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. Government Regulation of Environmental Matters - 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 our company to acquire permits and other authorizations for certain activities. 10 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. See "Republic of Bolivia--Environmental Matters." 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. Competition - 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. Holding Company Structure Risks - 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 our company 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 11 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. Requirement of External Financing - we may not be able to raise the funds necessary to explore and develop our mineral properties. We will need 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 could 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. Dependence on Key Personnel - we depend on the services of key executives. We are dependent on the services of key executives including our chairman and our chief operating 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 our company, 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. Substantial Control By Directors and Officers, and Shareholders - the substantial control of our company by the directors and officers, and shareholders may have a significant effect in delaying, deferring or preventing a change in control of our company or other events which could be of benefit to our other shareholders. As of March 1, 1999, Thomas S. Kaplan and the other directors of our company 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, beneficially owned approximately 34% of the outstanding shares of our company. This percentage includes approximately 1.4% owned by Paul Soros and his affiliates and approximately 6.7% owned by Eduardo Elsztain and his affiliates. In addition, as of March 1, 1999, Quantum Industrial Partners LDC and Geosor Corporation collectively owned approximately 17% of the outstanding shares of our company. George Soros, by virtue of his ownership of Geosor Corporation and his position with Soros Fund Management LLC, an investment advisor to Quantum Industrial Partners LDC, may have the power to direct the way that these shares are voted. This level of ownership by these persons may have a significant effect in delaying, deferring or preventing a change in control of our company or other events which could be of benefit to our other shareholders. 12 RATIOS OF EARNINGS TO FIXED CHARGES AND EARNINGS TO COMBINED FIXED CHARGES AND PREFERENCE SHARE DIVIDENDS Our company is a mining exploration and development company that holds a portfolio of silver exploration and development properties in South America and Central America. None of these properties are in production, and, consequently, our company has no current operating income or cash flow. Accordingly, no ratios are shown for any of the years ended December 31, 1994, 1995, 1996, 1997 and 1998 and the six-month period ended June 30, 1999 as earnings were not sufficient to cover fixed charges. As of the date of this prospectus, we have not issued any preference shares.

We have one of the largest, most diversified portfolios of privately owned and controlled silver exploration properties in the world. Since we were founded in 1993, we have added to our portfolio approximately 95 non-producing silver and other mineral properties located primarily in or near the traditional silver-producing regions of Bolivia, Peru, Chile, Honduras and Mexico. Since 1993, our exploration efforts have produced our first development project, the San Cristobal project located in southern Bolivia. Continued drilling and analysis of the properties relating to the San Cristobal project established that proven and probable reserves total 240 million tonnes of ore grading 2.0 ounces per tonne of silver, 1.67 percent zinc and 0.58 percent lead containing 470 million ounces of silver, 8.8 billion pounds of zinc and 3.1 billion pounds of lead. Proven and probable reserves were calculated using a $4.65 net smelter return per tonne cutoff value and market price assumptions of $5.00 per ounce of silver, $0.50 per pound of zinc and $0.28 per pound of lead. The following tables show our company's 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 for Sulfide Ore - San Cristobal Project -------------------------------------------------------------------- Average Grade Contained Metals(1) ------------------------------------- ------------------------------------- Tonnes Silver Zinc Lead Silver Zinc Lead of ore Grade Grade Grade Ounces Tonnes Tonnes (000s) (oz./tonne) (%) (%) (mm) (000s) (000s) ----------- ----------- ------------ ---------- ----------- ----------- ----------- 230.7 1.90 1.73 0.58 430.3 3,990 1,338 _______ (1) Amounts shown as contained metals do not reflect losses in the recovery process. Proven and probable reserves for sulfide ore include an average recovery of 68.75% for silver, 91.22% for zinc and 75.43% for lead.

Proven and probable reserves for oxide ore include an average recovery of 60% for silver and 50% for zinc. In addition to proven and probable reserves, Mine Reserve Associates, Inc. has estimated 46 million tonnes of mineralized material at an average grade of 2.90 ounces of silver per tonne, 1.04 percent zinc and 0.58 percent lead. We have completed a final, bankable feasibility study on the San Cristobal project. Based on the results of this study we anticipate developing a large scale, open pit mining operation with low stripping ratios, which we believe will be capable of processing 40,000 tonnes of ore per day using conventional mining and processing technologies. In addition, exploration efforts at other properties in Bolivia, Mexico and Peru indicate the presence of sufficient mineralization to warrant additional exploration and evaluation to determine the potential for future development. 16 Business Strategy We are one of a limited number of mining companies which focuses on silver exploration, development and production. Our strategy is to capitalize on 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. Our company is managed by a team of seasoned mining professionals with significant experience in the identification and exploration of mineral properties, as well as the construction, development and operation of large scale, open pit and underground, precious and base metals mining operations. The principal elements of our business strategy are to: . proceed to develop the San Cristobal project into a large scale open pit mining operation; . continue to explore and evaluate the Cobrizos silver property in southern Bolivia and the Platosa silver and zinc property in northern Mexico; . continue to explore and develop other 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. History, Principal Office We conduct substantially all of our operations through Apex Silver Mines and its subsidiaries. Apex Silver Mines was formerly Apex Silver Mines LDC and is our wholly owned subsidiary. Our company's material assets consist exclusively of the shares of Apex Silver Mines. We have a contract with Apex Silver Mines Corporation, a wholly owned subsidiary of Apex Silver Mines, under which Apex Silver Mines Corporation provides our company with strategic, financial, planning and other management services. Apex Silver Mines Corporation maintains its principal office at 1700 Lincoln Street, Suite 3050, Denver, Colorado 80203 and its telephone number is (303) 839-5060. Enforceability of Civil Liabilities Under United States Laws Our company is a Cayman Islands exempted company and some of our directors reside in jurisdictions outside of the United States. At any one time, all or a substantial portion of our assets and directors are or may be located in jurisdictions outside of the United States. Therefore, it could be difficult for investors to effect within the United States service of process on our company or any of the directors who reside outside the United States. Further, it could be difficult to recover against our company or directors judgments of courts in the United States, including judgments based upon civil liability under U.S. federal securities laws and similar state laws. Notwithstanding the foregoing, our company has irrevocably agreed that it may be served with process with respect to actions based on offers of the securities offered by this prospectus in the United States by serving Apex Silver Mines 17 Corporation, 1700 Lincoln Street, Suite 3050, Denver, Colorado 80203, its U.S. agent appointed for that purpose. W.S. Walker & Company, our Cayman Islands counsel, has advised our company that there may be circumstances where the courts of the Cayman Islands would not enforce: . judgments of U.S. courts obtained in actions against our company or directors of our company that are not resident within the United States that are based upon the civil liability provisions for the U.S. federal securities laws and similar state laws; or . original actions brought in the Cayman Islands against our company or directors of our company that are not resident within the United States based solely upon U.S. federal securities laws. There is no treaty in effect between the United States and the Cayman Islands providing for enforcement. There are grounds upon which Cayman Islands courts may not enforce judgments of U.S. courts. In addition, some remedies that are available under the laws of U.S. jurisdictions, including some remedies under U.S. federal securities laws, may not be allowed in Cayman Islands courts as being contrary to public policy. 18 REPUBLIC OF BOLIVIA We have compiled the following information from governmental and private publications. General Information Bolivia is situated in central South America and is bordered by Peru, Brazil, Paraguay, Argentina and Chile. It has an area of 1,098,581 square kilometers and a population of approximately 8.1 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. Sucre is the capital city of Bolivia. La Paz is the seat of government and, with a population of over one million people, the largest city in Bolivia. La Paz is situated on the Altiplano, the high plateau which separates the eastern and western ranges of the Andes. The land in this part of the country is largely semi-desert plains bordered by steep, rugged mountains. The eastern portion of the country consists of sparsely populated low-lands bordering the Brazilian Amazon basin where temperate and tropical forests dominate. Santa Cruz is the principal city of the low country with a population of approximately 1,000,000. The government of Bolivia consists of a directly elected president and a bicameral congress. Since the military government stepped down in 1982, Bolivia has maintained a stable democratic system with elections every four years. The current president, Hugo Banzer, was elected by the congress on August 5, 1997, after none of the presidential candidates succeeded in winning a majority of the votes in the general election held in June 1997. Economy The Bolivian economy has experienced continuous growth and relatively low, stable inflation in recent years. This economic performance is generally ascribed to the deregulation of key sectors of the economy, including oil and gas, communications, transportation and finance, and to foreign direct investment which has occurred as part of the recent privatization of formerly government-owned electricity, telecommunications, railways, aviation and oil and gas companies. The country's privatization program has involved (1) the sale of shares in government-owned entities in exchange for capital contributions to the privatized entities, and (2) the contribution of government-owned shares in privatized entities to trust funds established on behalf of all Bolivians over the age of 21 at the end of 1995. In connection with this program, we have entered into joint venture agreements with the government mining company, Comibol, with respect to two properties. Summary information on the Bolivian economy is set forth in the table below. 1994 1995 1996 1997 1998 GDP Growth............................................ 5.0% 3.7% 4.0% 4.2% 4.7% GDP per Capita........................................ $ 756 $ 812 $ 860 $1,005 $1,076 Inflation............................................. 8.5% 12.6% 7.9% 6.73% 4.39% Pubic Section Deficit (non-financial) as % of GDP.............................................. 3.2% 2.3% 2.1% 3.6% 4% Exports FOB (in millions)............................. $1,124 $1,181 $ 1326 $1,272 $1,206 Imports CIF (in millions)............................. $1,196 $1,433 $1,635 $1,906 $2,083 Current Account Balance (% GDP)....................... 3.6% 5.0% 5.2% -8% -10% Total Investment (in millions)........................ $ 794 $ 898 $ 540 $1,578 $1,754 Share of GDP (%)...................................... 13.3% 13.7% 7.6% 19.8% 20.5% Public Investment (in millions)....................... $ 481 $ 505 $ 524 $ 582 $ 539 Share of GDP (%)...................................... $ 481 $ 505 7.6% 7.3% 6.3% Private Investment (in millions)...................... $ 288 $ 373 $ 632 $ 996 $1,215 Share of GDP (%)...................................... 4.8% 5.7% 8.9% 12.5% 14.2% Source: Latin Finance 19 The official monetary unit of Bolivia is the boliviano, which was introduced in January 1987 following the adoption in 1985 of a broad based reform program known as the "New Economic Policy." In the mid-1980s, prior to the New Economic Policy, Bolivia suffered from hyperinflation, declining foreign investment, growing balance of payments deficits and a foreign exchange shortage fueled in part by an increasing disparity between the official and unofficial exchange rates. The New Economic Policy removed restrictions on exports and imports, ended most price controls and subsidies, instituted a freeze on public sector wages and subjected the public sector to rigorous cost cutting. By 1986, inflation was under control and the International Monetary Fund resumed stand-by assistance. During the period of the New Economic Policy, the gap between the official exchange rate and the parallel unofficial rate was bridged. On December 31, 1998, the exchange rate was 5.65 bolivianos to one U.S. dollar compared to the exchange rate on December 31, 1997 of 5.37 bolivianos to one U.S. dollar. Over the past year the boliviano has shown a tendency to depreciate approximately US$0.01 every 13 days; however this pace has accelerated recently in response to the devaluation of the Brazilian currency. The boliviano is freely convertible in Bolivia at a single, public exchange rate established by twice-weekly auctions held by the Bolivian Central Bank. Foreign Investment and Tax Since the New Economic Policy, most restrictions on trade have been removed or are in the process of being phased out. The remaining material restrictions applicable to mining in Bolivia are described below. Currently, import levies stand at ten percent for all items except capital goods, which are subject to a five percent levy. In March 1991, a new export code introduced further measures to liberalize trade. In order to prevent transfer pricing and other tax avoidance mechanisms, almost all foreign trade transactions require the filing of an aviso de conformidad describing the terms of the underlying transactions. The 1990 Investment 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 percent income tax. Taxable income is determined in accordance with Bolivian generally accepted accounting principles. Under the new Bolivian Mining Code, which came into effect on March 17, 1997, there is Complementary Mining Tax applicable to whomever carries out mining activities. Mining activities are defined to include: prospecting and exploration; mining or extracting minerals or metals; concentrating mine products; smelting and refining; and marketing of minerals and metals. The Complementary Mining Tax is calculated by applying an aliquot to the taxable base. The aliquot of the Complementary Mining Tax is a variable percentage indexed to the official U.S. dollar market price for the relevant metal or mineral. The variable percentage fluctuates between three percent and seven percent for precious stones and metals and between one percent and five percent for other metallic minerals. The taxable base is construed as the amount that results from multiplying the weight of the fine content of the mineral or metal by its official U.S. dollar market price. This tax is creditable against corporate income and is, in effect, a minimum tax on mining companies. If complementary mining tax payments in any fiscal year exceed corporate income tax payments, the excess is a credit against corporate income in the following year. Manufacturing or processing involving minerals is not subject to the Complementary Mining Tax. 20 Bolivian source income, including dividends, interest, management fees and expenses charged to a Bolivian company by foreign affiliates, is subject to a withholding tax of 12.5 percent, as is any of these payments when made to third parties. Operating losses are adjusted for inflation and may be carried forward and deducted from taxable income indefinitely. However, if accrued losses exceed 50 percent of capital, the capital must be increased. Bolivia assesses a 12.5 percent tax on profits of a branch of a foreign corporation operating in Bolivia. The branch tax is calculated on the book profits of the branch regardless of remittances. Any portion of the profits reinvested in Bolivia can be excluded from the taxable basis. Book profits are deemed remitted 120 days after the end of the fiscal year. There is a 13 percent value added tax on all sales, including mineral commodities, a five percent import duty on machinery and equipment and a ten percent duty on imported raw materials and components. The VAT paid on purchases is recoverable against VAT collected on Bolivian sales. Exports are not subject to VAT. The exporter can offset the VAT credit arising from purchases with domestic sales or can apply for a refund of import duties and VAT paid on inputs and raw materials included in the cost of exported goods. However, the refund of credits arising from imports is limited to 13 percent of the total value of the exports and therefore is not recoverable during the exploration phase. Mining Industry Bolivia produces a number of mineral commodities including tin, gold, silver, lead, zinc, antimony, tungsten, copper and bismuth. The country has long been a leading mineral and precious metals producer. Bolivia was colonized in the early sixteenth century by Spaniards who arrived in search of silver and gold. The extensive silver mining operations in Potosi which developed under Spanish rule led to the region being described as the "treasury of the Spanish empire." In the early twentieth century, tin became the country's leading mineral export although in recent years the focus has returned to gold, silver, lead and zinc. The country's principal mining regions are the eastern part of Bolivia along the Brazilian border, and the traditional mining areas of the Altiplano and Cordillera. Recent regulatory reforms have resulted in increased exploration activities, particularly with respect to precious metals. In the early 1990s, the government reformed the land tenure system, reduced taxes on mining operations, established equal treatment under the law between Comibol and foreign companies in obtaining mineral concessions, and created a national Mining Inventory Service which will maintain up-to-date information, including maps, for exploration and mining exploration concessions. Mining Concessions The Bolivian constitution states that all mineral deposits are the property of the State. Mining concessions, which may be awarded by the government, grant the holder, subject to the payment of patents, the real and 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. Individual mineral claims consist of indivisible squares shaped like an inverted pyramid, whose lower vertex is the center of the earth and whose surface area covers a total area of 25 hectares. Mining concessions are comprised of no fewer than one and no more than 2,500 adjacent squares. Mining concessions are distinct from the surface rights which comprise traditional land ownership; holders of mining concessions are entitled to explore and exploit a property and to use the water found at the property. Expropriation or the establishment of easements may not be legally carried out if the water supplies for a population are interrupted or negatively affected. 21 Holders of mining concessions are obliged to pay an annual mining patent. Co-owners are jointly and severally responsible for the patent payment. The patent is progressive and fees are based on the number of years of existence of the concession. Concessions established before the enactment of the new Mining Code, which comprise an area of up to 1,000 mining claims, pay the equivalent of $1.00 per claim per year. Concessions established before the enactment of the new Mining Code 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. All of our Bolivian concessions were established prior to enactment of the new Mining Code. Mining concessions are liable to forfeiture when the corresponding annual patent fails to be paid. Forfeiture is governed by law and does not require any administrative or judicial declaration. When a concession has been forfeited, the mining concession reverts to the State. Environmental Matters In 1992, the Bolivian government passed environmental legislation that established a comprehensive scheme for the initiation of a national environmental policy to protect the environment, promote sustainable development, promote the preservation of biological diversity and promote environmental education. Few environmental regulations specifically applicable to mineral exploration companies in Bolivia have been proclaimed to date. At present, concession holders must maintain waterways running through their concessions in their unspoiled state and concession holders must employ exploration and development techniques that will minimize environmental damage. Under Bolivia's environmental regulations, environmental impact assessments are required. In practice, foreign mining companies operating in Bolivia generally adhere to U.S. and European environmental standards for mining and exploration. The new Mining Code requires concession holders to minimize damage to surface rights, to neighboring concessions and to the environment. Concession holders are liable for damage or injury caused by their operations. Concession holders are not obliged to remediate environmental damage caused prior to the effectiveness of the new Mining Code or the date on which the mining concession was obtained, if the concession was granted at a later date. Upon becoming the owner of a concession, the concession holder must conduct an environmental audit to determine the extent of any environmental damage. If an environmental audit is not performed, the concession holder assumes the responsibility to mitigate all environmental damage. Environmental liabilities incurred under this new regime survive the existence or ownership of the relevant concession. Labor Market 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. One percent of the payroll tax is used for worker training. A large portion of the labor force that is engaged in wage employment is also unionized, although union participation is not mandatory. Strikes, the frequency of which have decreased greatly since the early 1980s, are not forbidden. However, before a strike may be called, all legally mandated alternatives, including negotiation, mediation and conciliation, must have been exhausted. Collective bargaining agreements are very rare, as negotiations are generally carried out between an individual company's union and management. 22 USE OF PROCEEDS Unless otherwise specified in a prospectus supplement, the net proceeds we receive from the sale of the securities offered by this prospectus and the accompanying prospectus supplement will be used for one or more of the following purposes: . constructing and developing the San Cristobal project; . exploring and developing properties in our portfolio; . maintaining control or ownership of our properties, including making ongoing lease and royalty payments and paying other maintenance and registration fees; . acquiring additional mining related properties or businesses; and . financing other general corporate purposes. DESCRIPTION OF THE DEBT SECURITIES The following description of the terms of the debt securities sets forth general terms that may apply to the debt securities. The particular terms of any debt securities will be described in the prospectus supplement relating to those debt securities. The debt securities will be either our senior debt securities or our subordinated debt securities. The senior debt securities will be issued under an indenture be entered into between our company and Wilmington Trust Company, as trustee for the senior debt securities. The subordinated debt securities will be issued under an indenture to be entered into between our company and Wilmington Trust FSB, as trustee for the subordinated debt securities. The following summary of the material provisions of the indentures is not complete. You should refer to the indentures, copies of which are exhibits to the registration statement of which this prospectus is a part. Section references below are to the section in the applicable indenture. We are a holding company that conducts substantially all of our operations through subsidiaries. As a result, claims of the holders of the debt securities will generally have a junior position to claims of creditors of our subsidiaries, except to the extent that our company may be recognized as a creditor of those subsidiaries. Claims of creditors of our subsidiaries other than our company may include substantial amounts of long-term debt, commercial paper and other short-term borrowings. General Neither indenture limits the amount of debt securities that we may issue under that indenture. Each indenture provides that debt securities may be issued up to the principal amount authorized by our company from time to time. The senior debt securities will have the same ranking as all of our other unsecured and unsubordinated debt. The subordinated debt securities will be unsecured and will be subordinated and junior to all senior indebtedness. The debt securities may be issued in one or more separate series of senior debt securities and/or subordinated debt securities. The prospectus supplement relating to the particular series of debt securities being offered will specify the particular amounts, prices and terms of those debt securities. These terms may include: 23 . the title of the debt securities; . any limit upon the aggregate principal amount of the debt securities; . the date or dates, or the method of determining the dates, on which the debt securities will mature; . the interest rate or rates of the debt securities, or the method of determining those rates, the interest payment dates and, for registered debt securities, the Regular Record Dates; . if a debt security is issued with original issue discount, the yield to maturity; . the places where payments may be made on the debt securities; . any mandatory or optional redemption provisions applicable to the debt securities; . any sinking fund or analogous provisions applicable to the debt securities; . any conversion or exchange provisions applicable to the debt securities; . any terms for the attachment to the debt securities of warrants, options or other rights to purchase or sell our securities; . the portion of the principal amount of the debt security payable upon the acceleration of maturity if other than the entire principal amount of the debt securities; . any deletions of, or changes or additions to, the events of default or covenants applicable to the debt securities; . if other than U.S. dollars, the currency or currencies, including European Currency Units, the euro and other composite currencies, in which payments of principal, premium and/or interest on the debt securities will be payable and whether the holder may elect payment to be made in a different currency; . the method of determining the amount of any payments on the debt securities which are linked to an index; . whether the debt securities will be issued in fully registered form without coupons or in bearer form, with or without coupons, or any combination of these, and whether they will be issued in the form of one or more global securities in temporary or definitive form; . any terms relating to the delivery of the debt securities if they are to be issued upon the exercise of warrants; . whether and on what terms we will pay additional amounts to holders of the debt securities that are not U.S. persons in respect of any tax, assessment or governmental charge withheld or deducted and, if so, whether and on what terms we will have the option to redeem the debt securities rather than pay the additional amounts; and 24 . any other specific terms of the debt securities. (Sections 2.2 and 3.1). Unless otherwise specified in the applicable prospectus supplement, (1) the debt securities will be registered debt securities and (2) debt securities denominated in U.S. dollars will be issued, in the case of registered debt securities, in denominations of $1,000 or an integral multiple of $1,000 and, in the case of bearer debt securities, in denominations of $5,000. Debt securities may bear legends required by United States federal tax law and regulations (Section 4.1). If any of the debt securities are sold for any foreign currency or currency unit or if any payments on the debt securities are payable in any foreign currency or currency unit, the prospectus supplement will contain any restrictions, elections, tax consequences, specific terms and other information with respect to the debt securities and the foreign currency or currency unit. Some of the debt securities may be issued as original issue discount debt securities. Original issue discount securities bear no interest during all or a part of the time that these debt securities are outstanding or bear interest at below-market rates and will be sold at a discount below their stated principal amount at maturity. The prospectus supplement will also contain special tax, accounting or other information relating to original issue discount securities or relating to other kinds of debt securities that may be offered, including debt securities linked to an index or payable in currencies other than U.S. dollars. Exchange, Registration and Transfer Debt securities may be transferred or exchanged at the corporate trust office of the security registrar or at any other office or agency maintained by our company for these purposes, without the payment of any service charge, except for any tax or governmental charges (Section 4.4). The senior trustee initially will be the designated security registrar in the United States for the senior debt securities. The subordinated trustee initially will be the designated security registrar in the United States for the subordinated debt securities. If debt securities are issuable as both registered debt securities and bearer debt securities, the bearer debt securities will be exchangeable for registered debt securities. Except as provided below, bearer debt securities will have outstanding coupons. If a bearer debt security with related coupons is surrendered in exchange for a registered debt security between a record date and the date set for the payment of interest, the bearer debt security will be surrendered without the coupon relating to that interest payment and that payment will be made only to the holder of the coupon when due. In the event of any redemption in part of any class or series of debt securities, we will not be required to: . issue, register the transfer of, or exchange, debt securities of any series between the opening of business 15 days before any selection of debt securities of that series to be redeemed and the close of business on: . if debt securities of the series are issuable only as registered debt securities, the day of mailing of the relevant notice of redemption, and . if debt securities of the series are issuable as bearer debt securities, the day of the first publication of the relevant notice of redemption or, if debt securities of the series are 25 also issuable as registered debt securities and there is no publication, the day of mailing of the relevant notice of redemption; . register the transfer of, or exchange, any registered debt security selected for redemption, in whole or in part, except the unredeemed portion of any registered debt security being redeemed in part; or . exchange any bearer debt security selected for redemption, except to exchange it for a registered debt security which is simultaneously surrendered for redemption. (Section 4.4). Payment and Paying Agent We will pay principal, interest and any premium on fully registered securities in the designated currency or currency unit at the office of a designated paying agent. Payment of interest on fully registered securities may be made at our option by check mailed to the persons in whose names the debt securities are registered on days specified in the indentures or any prospectus supplement. (Sections 4.6 and 4.10). We will pay principal, interest and any premium on bearer securities in the designated currency or currency unit at the office of a designated paying agent or agents outside of the United States. Payments will be made at the offices of the paying agent in the United States only if the designated currency is U.S. dollars and payment outside of the United States is illegal or effectively precluded. (Sections 4.10 and 11.2). If any amount payable on any debt security or coupon remains unclaimed at the end of two years after that amount became due and payable, the paying agent will release any unclaimed amounts to our company, and the holder of the debt security or coupon will look only to our company for payment. (Section 11.3). The designated paying agent in the United States for the senior debt securities initially will be the senior trustee located at 1100 North Market Street, Rodney Square North, Wilmington, Delaware. The designated paying agent in the United States for the subordinated debt securities initially will be the subordinated trustee located at 3773 Howard Hughes Parkway, Las Vegas, Nevada. Global Securities The debt securities of a series may be issued in whole or in part in the form of one or more global certificates that will be deposited with a depositary whom we will identify in a prospectus supplement. Global debt securities may be issued in either registered or bearer form and in either temporary or definitive form. All global debt securities in bearer form will be deposited with a depositary outside of the United States. We will describe the specific terms of the depositary arrangement with respect to a series of debt securities in the applicable prospectus supplement. Other than with respect to payments, we may treat a person having a beneficial interest in a definitive global debt security as the holder of the principal amount of outstanding debt securities represented by the definitive global debt security as specified in a written statement delivered to the trustee by the holder of the definitive global debt security, or, in the case of a definitive global debt security in bearer form, by a depositary in London for Morgan Guaranty Trust Company of New York, Brussels Office, as operator of the Euroclear System, and Cedel Bank, societe anonyme. (Section 4.11). Neither we, the trustee nor any of our respective agents will be responsible for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global debt security or for 26 maintaining, supervising or reviewing any records relating to these beneficial ownership interests. (Section 4.11). We anticipate that the following provisions will apply to all depositary arrangements with a depositary. Temporary Global Securities All or any portion of the debt securities of a series that are issuable as bearer debt securities initially may be represented by one or more temporary global debt securities, without interest coupons, to be deposited with Euroclear, and Cedel Bank for credit to the accounts of the beneficial owners of the debt securities or to other accounts as they may direct. On and after an exchange date provided in the applicable prospectus supplement, each temporary global debt security will be exchangeable for definitive debt securities in bearer form, registered form, definitive global bearer form or any combination of these forms, as specified in the prospectus supplement. No bearer debt security delivered in exchange for a portion of a temporary global debt security will be mailed or delivered to any location in the United States. (Sections 4.2 and 4.3). Interest on a temporary global debt security will be paid to Euroclear and/or Cedel Bank with respect to the portion held for its account only after they deliver to the trustee a certificate which states that the portion: . is not beneficially owned by a United States person; . has not been acquired by or on behalf of a United States person or for offer to resell or for resale to a United States person or any person inside the United States; or . if a beneficial interest has been acquired by a United States person, . that the person is a financial institution, as defined in the Internal Revenue Code, purchasing for its own account or has acquired the debt security through a financial institution and . that the debt securities are held by a financial institution that has agreed in writing to comply with the requirements of Section 165(j)(3)(A), (B) or (C) of the Internal Revenue Code and the regulations to the Internal Revenue Code and that it did not purchase for resale inside the United States. The certificate must be based on statements provided by the beneficial owners of interests in the temporary global debt security. Euroclear and Cedel Bank will credit the interest received by it to the accounts of the beneficial owners of the debt security or to other accounts as they may direct. (Section 4.3). "United States person" means a citizen or resident of the United States, a corporation, partnership or other entity created or organized in or under the laws of the United States or an estate or trust with income subject to United States federal income taxation regardless of its source. 27 Definitive Global Securities Bearer Securities. The applicable prospectus supplement will describe the exchange provisions, if any, of debt securities issuable in definitive global bearer form. We will not deliver any bearer debt securities delivered in exchange for a portion of a definitive global debt security to any location in the United States. (Section 4.4). U.S. Book-Entry Securities. Debt securities of a series represented by a definitive global registered debt security and deposited with or on behalf of a depositary in the United States will be represented by a definitive global debt security registered in the name of the depositary or its nominee. Upon the issuance of a global debt security and the deposit of the global debt security with the depositary, the depositary will credit, on its book-entry registration and transfer system, the respective principal amounts represented by that global debt security to the accounts of participating institutions that have accounts with the depositary or its nominee. The accounts to be credited shall be designated by the underwriters or agents for the sale of U.S. book-entry debt securities or by our company, if these debt securities are offered and sold directly by our company. Ownership of U.S. book-entry debt securities will be limited to participants or persons that may hold interests through participants. In addition, ownership of U.S. book-entry debt securities will be evidenced only by, and the transfer of that ownership will be effected only through, records maintained by the depositary or its nominee for the definitive global debt security or by participants or persons that hold through participants. So long as the depositary or its nominee is the registered owner of a global debt security, that depositary or nominee, as the case may be, will be considered the sole owner or holder of the U.S. book-entry debt securities represented by that global debt security for all purposes under the indenture. Payment of principal of, and premium and interest, if any, on, U.S. book-entry debt securities will be made to the depositary or its nominee as the registered owner or the holder of the global debt security representing the U.S. book-entry debt securities. Owners of U.S. book-entry debt securities: . will not be entitled to have the debt securities registered in their names; . will not be entitled to receive physical delivery of the debt securities in definitive form; and . will not be considered the owners or holders of the debt securities under the indenture. The laws of some jurisdictions require that purchasers of securities take physical delivery of securities in definitive form. These laws impair the ability to purchase or transfer U.S. book-entry debt securities. We expect that the depositary for U.S. book-entry debt securities of a series, upon receipt of any payment of principal of, or premium or interest, if any, on, the related definitive global debt security, will immediately credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global debt security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a global debt security held through those participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of those participants. 28 Covenants of the Company Limitation on Merger, Consolidation and Sales of Assets. We may, without the consent of the holders of the debt securities, merge into or consolidate with any other person, or convey or transfer all or substantially all of our company's properties and assets to another person provided that: . the successor assumes on the same terms and conditions all the obligations under the debt securities and the indentures; and . immediately after giving effect to the transaction, there is no default under the applicable indenture. (Section 9.1). The remaining or acquiring person will be substituted for our company in the indentures with the same effect as if it had been an original party to the indenture. (Section 9.2). A prospectus supplement will describe any other limitations on the ability of our company to merge into, consolidate with, or convey or transfer all or substantially all or our properties and assets to, another person. Satisfaction and Discharge; Defeasance We may be discharged from our obligations on the debt securities of any class or series that have matured or will mature or be redeemed within one year if we deposit with the trustee enough cash and/or U.S. government obligations or foreign government securities, as the case may be, to pay all the principal, interest and any premium due to the stated maturity or redemption date of the debt securities and comply with the other conditions set forth in the applicable indenture. The principal conditions that we must satisfy to discharge our obligations on any debt securities are (1) pay all other sums payable with respect to the applicable series of debt securities and (2) deliver to the trustee an officers' certificate and an opinion of counsel which state that the required conditions have been satisfied. (Section 5.1). Each indenture contains a provision that permits our company to elect to be discharged from all of our obligations with respect to any class or series of debt securities then outstanding. However, even if we effect a legal defeasance, some of our obligations will continue, including obligations to: . maintain and apply money in the defeasance trust, . register the transfer or exchange of the debt securities, . replace mutilated, destroyed, lost or stolen debt securities, and . maintain a registrar and paying agent in respect of the debt securities. Each indenture also permits our company to elect to be released from our obligations under specified covenants and from the consequences of an event of default resulting from a breach of those covenants. To make either of the above elections, we must deposit in trust with the trustee cash and/or U.S. government obligations, if the debt securities are denominated in U.S. dollars, and/or foreign government securities if the debt securities are denominated in a foreign currency, which through the payment of principal and interest under their terms will provide sufficient amounts, without reinvestment, to repay in full those debt securities. As a condition to legal defeasance or covenant defeasance, we must deliver to the trustee an opinion of counsel that the holders of the debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit and defeasance and 29 will be subject to U.S. federal income tax in the same amount and in the same manner and times as would have been the case if the deposit and defeasance had not occurred. In the case of a legal defeasance only, the opinion of counsel must be based on a ruling of the U.S. Internal Revenue Service or other change in applicable U.S. federal income tax law. (Section 5.3). The indentures specify the types of U.S. government obligations and foreign government securities that we may deposit. Events of Default, Notice and Waiver Each indenture defines an event of default with respect to any class or series of debt securities as one or more of the following events: . failure to pay interest on any debt security of the class or series for 30 days when due; . failure to pay the principal or any premium on any debt securities of the class or series when due; . failure to make any sinking fund payment for 30 days when due; . failure to perform any other covenant in the debt securities of the series or in the applicable indenture with respect to debt securities of the series for 90 days after being given notice; and . occurrence of an event of bankruptcy, insolvency or reorganization set forth in the indenture. An event of default for a particular class or series of debt securities does not necessarily constitute an event of default for any other class or series of debt securities issued under an indenture. (Section 6.1). In the case of an event of default arising from events of bankruptcy or insolvency set forth in the indenture, all outstanding debt securities will become due and payable immediately without further action or notice. If any other event of default as to a series of debt securities occurs and is continuing, the trustee or the holders of at least 25% in principal amount of the then outstanding debt securities of that series may declare all the debt securities to be due and payable immediately. The holders of a majority in aggregate principal amount of the debt securities then outstanding by notice to the trustee may on behalf of the holders of all of the debt securities of that series waive any existing default or event of default and its consequences under the applicable indenture except a continuing default or event of default in the payment of interest on, or the principal of, the debt securities of that series. Each indenture requires the trustee to, within 90 days after the occurrence of a default known to it with respect to any outstanding series of debt securities, give the holders of that class or series notice of the default if uncured or not waived. However, the trustee may withhold this notice if it determines in good faith that the withholding of this notice is in the interest of those holders, except that the trustee may not withhold this notice in the case of a payment default. The term "default" for the purpose of this provision means any event that is, or after notice or lapse of time or both would become, an event of default with respect to debt securities of that series. (Section 7.2). Other than the duty to act with the required standard of care during an event of default, a trustee is not obligated to exercise any of its rights or powers under the applicable indenture at the request or direction of any of the holders of debt securities, unless the holders have offered to the trustee reasonable security and indemnity. (Section 7.3). Each indenture provides that the holders of a majority in principal amount of outstanding debt securities of any series may direct the time, method and place of conducting 30 any proceeding for any remedy available to the trustee, or exercising any trust or other power conferred on the trustee if the direction would not conflict with any rule of law or with the indenture. However, the trustee may take any other action that it deems proper which is not inconsistent with any direction and may decline to follow any direction if it in good faith determines that the directed action would involve it in personal liability. (Section 6.12). Each indenture includes a covenant that we will file annually with the trustee a certificate of no default, or specifying any default that exists. (Section 11.4). Modification of the Indentures We and the applicable trustee may modify an indenture without the consent of the holders for limited purposes, including adding to our covenants or events of default, establishing forms or terms of debt securities, curing ambiguities and other purposes which do not adversely affect the holders in any material respect. (Section 10.1). We and the applicable trustee may make modifications and amendments to an indenture with the consent of the holders of a majority in principal amount of the outstanding debt securities of all affected series. However, without the consent of each affected holder, no modification may: . change the stated maturity of any debt security; . reduce the principal, premium, if any, or rate of interest on any debt security; . change any place of payment or the currency in which any debt security is payable; . impair the right to enforce any payment after the stated maturity or redemption date; . adversely affect the terms of any conversion right; . reduce the percentage of holders of outstanding debt securities of any series required to consent to any modification, amendment or waiver under the indenture; . change any of our obligations, with respect to outstanding debt securities of a series, to maintain an office or agency in the places and for the purposes specified in the indenture for the series; or . change the provisions in the indenture that relate to its modification or amendment other than to increase the percentage of outstanding debt securities of any series required to consent to any modification or waiver under the indenture. (Section 10.2). Meetings The indentures contain provisions for convening meetings of the holders of debt securities of a series. (Section 14.1). A meeting may be called at any time by the trustee and also, upon request, by our company or the holders of at least 25% in principal amount of the outstanding debt securities of a series, in any case upon notice given in accordance with "Notices" below. (Section 14.2). Persons holding a majority in principal amount of the outstanding debt securities of a series will constitute a quorum at a meeting. A meeting called by our company or the trustee that does not have a quorum may be adjourned for not less than 10 days. If there is not a quorum at the adjourned meeting, the meeting may be further adjourned for not less than 10 days. 31 Any resolution presented at a meeting at which a quorum is present may be adopted by the affirmative vote of the holders of a majority in principal amount of the outstanding debt securities of that series, except for any consent which must be given by the holders of each debt security affected by the modifications or amendments of an indenture described above under "Modification of the Indentures." However, a resolution with respect to any request, demand, authorization, direction, notice, consent, waiver, or other action which may be made, given, or taken by the holders of a specified percentage, which is equal to or less than a majority, in principal amount of outstanding debt securities of a series may be adopted at a meeting at which a quorum is present by the affirmative vote of the holders of the specified percentage in principal amount of the outstanding debt securities of that series. Any resolution passed or decision taken at any meeting of holders of debt securities of any series duly held in accordance with an indenture will be binding on all holders of debt securities of that series and the related coupons. The indentures provide that specified consents, waivers and other actions may be given by the holders of a specified percentage of outstanding debt securities of all series affected by the modification or amendment, acting as one class. For purposes of these consents, waivers and actions, only the principal amount of outstanding debt securities of any series represented at a meeting at which a quorum is present and voting in favor of the action will be counted for purposes of calculating the aggregate principal amount of outstanding debt securities of all series affected by the modification or amendment favoring the action. (Section 14.4). Notices In most instances, notices to holders of bearer debt securities will be given by publication at least once in a daily newspaper in New York, New York and in London, England and in other cities as may be specified in the bearer debt securities and will be mailed to those persons whose names and addresses were previously filed with the applicable trustee, within the time prescribed for the giving of the notice. Notice to holders of registered debt securities will be given by mail to the addresses of those holders as they appear in the security register. (Section 1.6). Title Title to any bearer debt securities and any related coupons will pass by delivery. We, the trustee, and any agent of ours or the trustee may treat the holder of any bearer debt security or related coupon and, prior to due presentment for registration of transfer, the registered owner of any registered debt security as the absolute owner of that debt security for the purpose of making payment and for all other purposes, regardless of whether or not that debt security or coupon shall be overdue and notwithstanding any notice to the contrary (Section 4.7). Replacement of Securities Coupons Debt securities or coupons that have been mutilated will be replaced by our company at the expense of the holder upon surrender of the mutilated debt security or coupon to the security registrar. Debt securities or coupons that become destroyed, stolen, or lost will be replaced by our company at the expense of the holder upon delivery to the security registrar of evidence of its destruction, loss, or theft satisfactory to our company and the security registrar. In the case of a destroyed, lost, or stolen debt security or coupon, the holder of the debt security or coupon may be required to provide reasonable security or indemnity to the trustee and our company before a replacement debt security will be issued. (Section 4.5). 32 Governing Law The indentures, the debt securities, and the coupons will be governed by, and construed under, the laws of the State of New York without regard to the principles of conflicts of laws. Concerning the Trustees We may from time to time maintain lines of credit, and have other customary banking relationships, with any of the trustees. Senior Debt Securities The senior debt securities will rank equally with all of our company's other unsecured and non-subordinated debt. Covenants in the Senior Indenture The prospectus supplement relating to a series of senior debt securities will describe any material covenants in respect of that series of senior debt securities. Subordinated debt securities The subordinated debt securities will be unsecured. The subordinated debt securities will be subordinate in right of payment to all senior indebtedness. (Section 15.1 of subordinated indenture). In addition, claims of creditors and preferred shareholders of our subsidiaries generally will have priority with respect to the assets and earnings of our subsidiaries over the claims of our creditors, including holders of the subordinated debt securities, even though those obligations may not constitute senior indebtedness. The subordinated debt securities, therefore, will be effectively subordinated to creditors, including trade creditors, and preferred shareholders of our subsidiaries with regard to the assets of our subsidiaries. Creditors of our subsidiaries include trade creditors, secured creditors and creditors holding guarantees issued by our subsidiaries. Unless otherwise specified in a prospectus supplement, senior indebtedness shall mean the principal of, premium, if any, and interest on, . all indebtedness for money borrowed by our company and . any deferrals, renewals, or extensions of any senior indebtedness. Indebtedness for money borrowed by our company includes all indebtedness of another person for money borrowed that we guarantee, other than the subordinated debt securities, whether outstanding on the date of execution of the subordinated indenture or created, assumed or incurred after the date of the subordinated indenture. However, senior indebtedness will not include any indebtedness that expressly states to have the same rank as the subordinated debt securities or to rank junior to the subordinated debt securities. Senior indebtedness will also not include: . any of our obligations to our subsidiaries; and . any liability for federal, state, local or other taxes owed or owing by our company. 33 The senior debt securities constitute senior indebtedness under the subordinated indenture. A prospectus supplement will describe the relative ranking among different series of subordinated debt securities. Unless otherwise specified in a prospectus supplement, we may not make any payment on the subordinated debt securities and may not purchase, redeem, or retire any subordinated debt securities if . any senior indebtedness is not paid when due or . the maturity of any senior indebtedness is accelerated as a result of a default, unless the default has been cured or waived and the acceleration has been rescinded or the senior indebtedness has been paid in full. We may, however, pay the subordinated debt securities without regard to these limitations if the subordinated trustee and our company receive written notice approving the payment from the representatives of the holders of senior indebtedness with respect to which either of the events set forth above has occurred and is continuing. Unless otherwise specified in a prospectus supplement, during the continuance of any default with respect to any designated senior indebtedness under which its maturity may be accelerated immediately without further notice or the expiration of any applicable grace periods, we may not pay the subordinated debt securities for 90 days after the receipt by the subordinated trustee of written notice of a default from the representatives of the holders of designated senior indebtedness. If the holders of designated senior indebtedness or the representatives of those holders have not accelerated the maturity of the designated senior indebtedness at the end of the 90 day period, we may resume payments on the subordinated debt securities. Only one notice may be given in any consecutive 360-day period, irrespective of the number of defaults with respect to designated senior indebtedness during that period. (Section 15.3 of subordinated indenture). In the event that we pay or distribute our company's assets to creditors upon a total or partial liquidation, dissolution or reorganization of our company or our company's property, the holders of senior indebtedness will be entitled to receive payment in full of the senior indebtedness before the holders of subordinated debt securities are entitled to receive any payment. Until the senior indebtedness is paid in full, any payment or distribution to which holders of subordinated debt securities would be entitled but for the subordination provisions of the subordinated indenture will be made to holders of the senior indebtedness as their interests may appear. However, holders of subordinated debt securities will be permitted to receive distributions of shares and debt securities subordinated to the senior indebtedness. (Section 15.2 of subordinated indenture). If a distribution is made to holders of subordinated debt securities that, due to the subordination provisions, should not have been made to them, the holders of subordinated debt securities are required to hold it in trust for the holders of senior indebtedness, and pay it over to them as their interests may appear. (Section 15.5 of subordinated indenture). If payment of the subordinated debt securities is accelerated because of an event of default, either we or the subordinated trustee will promptly notify the holders of senior indebtedness or the representatives of the holders of the acceleration. We may not pay the subordinated debt securities until five business days after the holders or the representatives of the senior indebtedness receive notice of the acceleration. Afterwards, we may pay the subordinated debt securities only if the subordination provisions of the subordinated indenture otherwise permit payment at that time. (Section 15.4 of subordinated indenture). As a result of the subordination provisions contained in the subordinated indenture, in the event of insolvency, our creditors who are holders of senior indebtedness may recover more, ratably, than the holders of subordinated debt securities. In addition, our creditors who are not holders of senior 34 indebtedness may recover less, ratably, than holders of senior indebtedness and may recover more, ratably, than the holders of subordinated indebtedness. The prospectus supplement relating to a series of subordinated debt securities will describe any material covenants in respect of any series of subordinated debt securities. DESCRIPTION OF THE PREFERENCE SHARES The following is a description of the material general terms and provisions of the preference shares. The particular terms of any class or series of preference shares will be described in the applicable prospectus supplement. The following summary of terms of our preference shares is not complete. You should refer to the provisions of our Memorandum of Association, the Articles of Association and the resolutions of the Board of Directors relating to the approval and terms of each class or series of the preference shares which will be filed with the SEC at or prior to the time of issuance of a class or series of the preference shares. We are authorized to issue up to 75,000,000 shares of our company, par value $.01 per share. The Board of Directors has the power to designate whether an issue of shares shall be ordinary shares or preference shares. As of December 31, 1998, 26,250,761 ordinary shares were outstanding and no preference shares were outstanding. Subject to limitations prescribed by law, the Board of Directors is authorized at any time to: . issue one or more classes or series of preference shares; . determine the designation for any class or series of preference shares; and . determine the number of shares in any class or series. The Board of Directors in approving the issuance of a class or series of preference shares shall determine, and the applicable prospectus supplement will set forth with respect to the class or series, the following: . whether dividends on that class or series of preference shares will be cumulative or non-cumulative; . the dividend rate and rights in respect of dividends on the preference shares of that class or series; . the liquidation preference per share of that class or series of preference shares, if any; . the voting powers, if any, of the preference shares of that class or series; . any redemption and sinking fund provisions applicable to that class or series of preference shares; . any conversion provisions applicable to that class or series of preference shares; . the terms of any other preferences or other rights and limitations, if any, applicable to that class or series of preference shares. 35 Dividends Holders of preference shares will be entitled to receive, when, as and if declared by the Board of Directors, cash dividends at the rates and on the dates as set forth in the prospectus supplement. Except as set forth below, no dividends will be declared or paid on any class or series of preference shares unless full dividends for all classes or series of preference shares which have the same rank as, or rank senior to, that class or series of preference shares, including any unpaid cumulative dividends, have been or contemporaneously are declared and paid. When those dividends are not paid in full, dividends will be declared pro rata so that the amount of dividends declared per share on that class or series of preference shares and on each other class or series of preference shares having the same rank as, or ranking senior to, that class or series of preference shares will in all cases bear to each other the same ratio that accrued dividends per share on that class or series of preference shares and the other preference shares bear to each other. In addition, generally, unless all dividends on the preference shares have been paid, no dividends will be declared or paid on the ordinary shares and generally we may not redeem or purchase any ordinary shares. Convertibility No class or series of preference shares will be convertible into, or exchangeable for, other securities or property except as set forth in the prospectus supplement. Redemption and Sinking Fund No class or series of preference shares will be redeemable or receive the benefit of a sinking fund except as set forth in the prospectus supplement. Liquidation In the event we voluntarily or involuntarily liquidate, dissolve, or wind up our affairs, the holders of each class or series of preference shares will be entitled to receive the liquidation preference per share specified in the prospectus supplement plus an amount equal to accrued and unpaid dividends, if any, before any distribution to the holders of ordinary shares. If the amounts payable with respect to preference shares are not paid in full, the holders of preference shares will share ratably in any distribution of assets based upon the aggregate liquidation preference for all outstanding shares for each class or series. After the holders of preference shares are paid in full, they will have no right or claim to any of our remaining assets. Voting Except as indicated below or in the prospectus supplement, the holders of preference shares will not be entitled to vote. If the equivalent of six quarterly dividends payable on any class or series of preference shares is in default, the number of directors constituting our Board of Directors will be increased by two and the holders of that class or series of preference shares, voting together as a class with all other classes or series of preference shares entitled to vote on the election of directors, will be entitled to elect those additional directors. In the event of a default, the Board of Directors will call a special meeting for the holders of all affected classes or series within 10 business days of the default for the purpose of electing the additional directors. Alternatively, the holders of record of a majority of the outstanding shares of all affected classes or series who are entitled to participate in the election of directors may elect the additional directors by written consent. If all accumulated dividends on any class or series of preference shares have been paid in full, the holders of shares of that class or series will no 36 longer have the right to vote on directors and the term of office of each director so elected will terminate and the number of our directors will, without further action, be reduced by two. The majority vote of the holders of two-thirds of the outstanding shares of each class or series of preference shares voting together as a class, is required to authorize any amendment, alteration or repeal of the Articles of Association, the Memorandum of Association or the adoption of a special resolution by the shareholders of our company which would adversely affect the powers, preferences or special rights of the preference shares, including authorizing any class or series of shares with superior dividend and liquidation preferences. Miscellaneous The holders of preference shares will have no preemptive rights. The preference shares, when issued, will be fully paid and nonassessable. Preference shares that we redeem or otherwise reacquire will resume the status of authorized and unissued shares of share capital undesignated as to class or series, and will be available for subsequent issuance. There are no restrictions on repurchase or redemption of the preference shares while there is any arrearage on sinking fund installments except as may be set forth in a prospectus supplement. Neither the par value nor the liquidation preference is indicative of the price at which the preference shares will actually trade on or after the date of issuance. Payment of dividends on any class or series of preference shares may be restricted by loan agreements, indentures and other transactions we may enter into. No Other Rights The shares of a class or series of preference shares will not have any preferences, voting powers or relative, participating, optional or other special rights except as set forth above or in the prospectus supplement, the Memorandum of Association, the Articles of Association, the Board of Directors' resolution approving the issuance of preference shares or as otherwise required by law. Transfer Agent and Registrar The transfer agent for each class or series of preference shares will be described in the prospectus supplement. DESCRIPTION OF THE DEPOSITARY SHARES We may, at our option, elect to offer fractional shares of preference shares, rather than full shares of preference shares. If we do, we will issue to the public receipts for depositary shares and each of these depositary shares will represent a fraction of a share of a particular class or series of preference shares. Each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in shares of preference shares overlying that depositary share, to all rights and preferences of the preference shares overlying that depositary share. Those rights include dividend, voting, redemption and liquidation rights. The particular terms of any depositary shares will be described in the applicable prospectus supplement. The shares of preference shares overlying the depositary shares will be deposited with a bank or trust company selected by our company under a deposit agreement between our company, the depositary and the holders of the depositary receipts. A depositary receipt will evidence the depositary shares issued under the deposit agreement. The depositary will be the transfer agent, registrar, and dividend disbursing agent for the depositary shares. 37 Holders of depositary receipts will agree to be bound by the deposit agreement. Any actions required to be taken by holders of depositary receipts, including filing proof of residence and paying applicable charges, will be set forth in the deposit agreement.
