USE OF PROCEEDS Because the shares of common stock will be issued in exchange for or upon the redemption of the exchangeable shares, we will not receive any cash proceeds upon the issuance of the common stock. DESCRIPTION OF THE COMMON STOCK The following description of the common stock is only a summary and is not intended to be comprehensive. For additional information you should refer to the applicable provisions of the North Carolina Business Corporation Act and our Restated Articles of Incorporation ("Articles") and By-Laws. The Articles and By-Laws are exhibits to the registration statement, of which this prospectus is a part. GENERAL We are authorized to issue up to 2,000,000,000 shares of common stock. At February 28, 2002, 778,199,474 shares of common stock were outstanding. We are also authorized to issue up to 12,500,000 shares of Preferred Stock, 10,000,000 shares of Preferred Stock A and 1,500,000 shares of Preference Stock. At February 28, 2002, 2,154,984 shares of Preferred Stock, 1,257,185 shares of Preferred Stock A and no shares of Preference Stock were outstanding. The Preferred Stock, Preferred Stock A and Preference Stock together are sometimes called the "Preferred Stocks." DIVIDENDS Holders of common stock are entitled to such dividends as may be declared from time to time by the Board of Directors from legally available funds but only if full dividends on all outstanding series of the Preferred Stocks for the then current and all prior dividend periods and any required sinking fund payments with respect to any outstanding series of such securities have been paid or provided for. 3 VOTING RIGHTS Subject to the rights, if any, of the holders of the Preferred Stocks which may be outstanding or as otherwise provided by law, the holders of common stock have exclusive voting rights, each share being entitled to one vote. Holders of common stock have noncumulative voting rights, which means that the holders of more than 50% of the shares voting for the election of directors can elect 100% of the directors and the holders of the remaining shares voting for the election of directors will not be able to elect any directors. Whenever dividends on any part of any outstanding Preferred Stock or Preferred Stock A are in arrears in an amount equivalent to the total dividends required to be paid on that Preferred Stock or Preferred Stock A in any period of 12 calendar months, the holders of the Preferred Stock as a class have the exclusive right to elect a majority of the authorized number of directors and the holders of the Preferred Stock A as a class have the exclusive right to elect two directors. Those rights cease whenever we pay all accrued and unpaid dividends in full. Whenever six quarterly dividends on any outstanding series of the Preference Stock are in arrears or any required sinking fund payments are in default, the holders of the Preference Stock as a class have the exclusive right to elect two directors. This right ceases whenever all dividends and required sinking fund obligations in default have been paid in full or provided for. In addition, the consent of the holders of specified percentages of any outstanding Preferred Stock, Preferred Stock A or Preference Stock, or some or all of the holders of such classes, is required in connection with certain increases in authorized amounts of or changes in stock senior to the common stock or in connection with any sale of substantially all of our assets or certain mergers. RIGHTS UPON LIQUIDATION The holders of common stock are entitled in liquidation to share ratably in our assets after payment of all debts and liabilities and after required preferential payments to the holders of outstanding Preferred Stocks. MISCELLANEOUS The outstanding shares of common stock are, and the shares of common stock issued hereunder will be, upon payment for them, fully paid and nonassessable. Holders of common stock have no preemptive rights and no conversion rights. The common stock is not subject to redemption and is not entitled to the benefit of any sinking fund provisions. TRANSFER AGENT AND REGISTRAR We act as transfer agent and registrar for the common stock. PREFERENCE STOCK PURCHASE RIGHTS Each share of common stock has attached to it a Preference Stock Purchase Right. The Preference Stock Purchase Rights initially are represented only by the certificates for the shares of common stock and will not trade separately from those shares unless and until: - ten days after it is publicly announced that a person or group (with certain exceptions) has acquired, or has obtained the right to acquire, the beneficial ownership of 15% or more of the outstanding common stock (an "acquiring person"); or - ten business days (or a later date determined by our Board of Directors) after the date a person or group commences, or public announcement is made that the person or group intends to commence, a tender or exchange offer that would result in the person or group becoming an acquiring person. If and when the Preference Stock Purchase Rights separate, each Preference Stock Purchase Right will entitle the holder to purchase 1/10,000 of a share of our Series A Participating Preference Stock for an exercise price that is presently $190. 4 In the event that a person or group becomes an acquiring person, each Preference Stock Purchase Right (except for Preference Stock Purchase Rights beneficially owned by the acquiring person or its transferees, which Preference Stock Purchase Rights become void) will entitle its holder to purchase, for the exercise price, a number of shares of common stock having a market value of twice the exercise price. Also, if, after ten days following the date of the announcement that a person or group has become an acquiring person: - we are involved in a merger or similar form of business combination in which we are not the surviving corporation or in which we are the surviving corporation but the common stock is changed or exchanged; or - more than 50% of our assets or earning power is sold or transferred; then each Preference Stock Purchase Right (except for voided Preference Stock Purchase Rights) will entitle its holder to purchase, for the exercise price, a number of shares of common stock of the acquiring company having a value of twice the exercise price. If any person or group acquires from 15% to but excluding 50% of the outstanding common stock, our Board of Directors may, at its option, exchange each outstanding Preference Stock Purchase Right (except for those held by an acquiring person or its transferees) for one share of common stock or 1/10,000 of a share of Series A Participating Preference Stock. Our Board of Directors may redeem the Preference Stock Purchase Rights for $0.01 per Preference Stock Purchase Right prior to ten business days after the date of the public announcement that a person or group has become an acquiring person. The Preference Stock Purchase Rights will not prevent a takeover of us. However, the existence of the Preference Stock Purchase Rights may cause substantial dilution to a person or group that acquires 15% or more of the common stock unless the Board of Directors first redeems those Preference Stock Purchase Rights. CERTAIN ANTI-TAKEOVER MATTERS Our Articles and By-Laws include a number of provisions that may have the effect of encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with the Board of Directors rather than pursue non-negotiated takeover attempts. Those provisions include: CLASSIFIED BOARD OF DIRECTORS; REMOVAL OF DIRECTORS; VACANCIES Our Articles provide for a Board of Directors divided into three classes, with one class being elected each year to serve for a three-year term. As a result, at least two annual meetings of shareholders may be required for shareholders to change a majority of the Board of Directors. Our shareholders may remove directors only for cause. Vacancies and newly created directorships on the Board of Directors may be filled only by the affirmative vote of a majority of the directors remaining in office, and no decrease in the number of directors may shorten the term of an incumbent director. The classification of directors and the inability of shareholders to remove directors without cause or to fill vacancies and newly created directorships on the Board of Directors will make it more difficult to change the composition of the Board of Directors, but will promote continuity of existing management. ADVANCE NOTICE REQUIREMENTS Our By-Laws establish advance notice procedures with regard to shareholder proposals relating to the nomination of persons for election as directors or new business to be brought before annual meetings of shareholders. These procedures provide that shareholders must give timely notice of such proposals in writing to the Secretary of Duke Energy. Generally, to be timely with respect to an annual meeting of shareholders, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year. The notice must contain certain information specified in the By-Laws. 5 SPECIAL MEETINGS OF SHAREHOLDERS Neither our Articles nor our By-Laws give shareholders the right to call a special meeting of shareholders. The By-Laws provide that special meetings of shareholders may be called only by the Board of Directors or the Chairman of the Board. AMENDMENT OF CERTAIN CHARTER PROVISIONS Our Articles require the approval of not less than 80% of the voting power of all outstanding shares of Duke Energy capital stock entitled to vote generally in the election of directors, voting together as a single class, to amend provisions relating to the minimum and maximum size of the Board of Directors, the classification of the Board of Directors, the removal of directors, the filling of vacancies and newly created directorships on the Board of Directors and the requirement that a decrease in the number of directors constituting the Board of Directors may not shorten the term of any incumbent director. This amendment provision will make it more difficult to dilute the anti-takeover effects of our Articles and By-Laws. PLAN OF DISTRIBUTION We will distribute the shares of common stock covered by this prospectus only upon exchange or redemption of the exchangeable shares of Exchangeco, and no broker, dealer or underwriter has been engaged in connection with the exchange or redemption. Each exchangeable share of Exchangeco may be exchanged or redeemed for one share of common stock. We will pay all expenses incurred in connection with the distribution described in this prospectus. INCOME TAX CONSIDERATIONS CANADIAN FEDERAL INCOME TAX CONSIDERATIONS In the opinion of Stikeman Elliott, our Canadian counsel, the following is an accurate summary of the principal Canadian federal income tax considerations under the Canadian Income Tax Act generally applicable to you if you hold exchangeable shares or acquire common stock on the redemption, retraction or exchange of exchangeable shares and if, for purposes of the Canadian Income Tax Act, you are or are deemed to be resident in Canada at all relevant times, you deal with us at arm's length, you are not affiliated with us and you hold your exchangeable shares and will hold the common stock as capital property. This discussion does not apply to you if you are a "financial institution," as defined in the Canadian Income Tax Act, and are therefore subject to the mark-to-market rules of the Canadian Income Tax Act. This summary also does not apply to you if Duke Energy is or will be a "foreign affiliate" of you for purposes of the Canadian Income Tax Act. The exchangeable shares and common stock will generally be considered to be capital property to you unless the shares are held by you in the course of carrying on a business or the shares are acquired in a transaction considered to be an adventure in the nature of trade. If the exchangeable shares might not otherwise qualify as capital property, you may be entitled to obtain this qualification by making the irrevocable election provided under subsection 39(4) of the Canadian Income Tax Act. If you do not hold your exchangeable shares or will not hold common stock as capital property, you should consult your own tax advisors for information and advice having regard to your particular circumstances. This summary is based on the current provisions of the Canadian Income Tax Act and regulations, the current provisions of the Convention Between the United States of America and Canada with Respect to Taxes on Income and on Capital, signed September 26, 1980, as amended and our Canadian counsel's understanding of the current published administrative practices of the Canada Customs and Revenue Agency (the "CCRA"). This summary takes into account all specific proposals to amend the Canadian Income Tax Act and regulations that have been publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof and assumes that all of these proposed amendments will be enacted in their present form. No assurances can be given that any proposed amendments will be enacted 6 in the form proposed, or at all. This summary is not exhaustive of all possible Canadian federal income tax considerations and, except for the foregoing, does not take into account or anticipate any changes in law, whether by legislative, administrative or judicial decision or action, nor does it take into account provincial, territorial or foreign income tax legislation or considerations, which may differ from the Canadian federal income tax considerations described below. No advance income tax ruling has been sought or obtained from the CCRA to confirm the tax consequences of any of the transactions relating to the exchangeable shares or the acquisition of the common stock on the redemption, retraction or exchange of exchangeable shares. For purposes of the Canadian Income Tax Act, all amounts relating to the acquisition, holding or disposition of common stock, including dividends, adjusted cost base amounts and proceeds of disposition, must be converted into Canadian dollars based on the prevailing United States dollar exchange rate generally at the time these amounts arise. THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, AND SHOULD NOT BE CONSTRUED TO BE, LEGAL, BUSINESS OR TAX ADVICE TO YOU. THEREFORE, YOU SHOULD CONSULT YOUR OWN TAX ADVISORS WITH RESPECT TO YOUR PARTICULAR CIRCUMSTANCES. REDEMPTION OR EXCHANGE OF EXCHANGEABLE SHARES On a redemption (including a retraction) of your exchangeable shares by Exchangeco, you will be deemed to have received a dividend equal to the amount, if any, by which the redemption proceeds exceed the paid-up capital (for purposes of the Canadian Income Tax Act) of the exchangeable shares so redeemed. For these purposes, the redemption proceeds will be the fair market value of the common stock received from Exchangeco on the redemption plus the amount, if any, of all payable and unpaid dividends on the exchangeable shares paid on the redemption. The amount of any such deemed dividend will be subject to the tax treatment described below under "Dividends on Exchangeable Shares." On a redemption (including a retraction) of your exchangeable shares, you will also be considered to have disposed of your exchangeable shares, but the amount of the deemed dividend will be excluded in computing your proceeds of disposition for purposes of computing any capital gain or capital loss arising on the disposition. If you are a corporation, in some circumstances the amount of any such deemed dividend may be treated as proceeds of disposition and not as a dividend. The taxation of capital gains and capital losses is described below. On an exchange of your exchangeable shares with our indirect wholly-owned subsidiary, Duke Energy Canada Call Co. (hereinafter referred to as "Callco"), or with us for the common stock, you will generally realize a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition of your exchangeable shares, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base to you of the exchangeable shares immediately before the exchange. For these purposes, the proceeds of disposition will be the fair market value at the time of the exchange of the common stock which you receive plus any other amounts received from us as part of the exchange, but less any amount paid in satisfaction of declared and unpaid dividends owed to you by Exchangeco. The taxation of capital gains and capital losses is described below. On October 18, 2000, the Minister of Finance announced that the Department of Finance will consider future amendments to the Canadian Income Tax Act to allow holders of shares of a Canadian corporation to exchange such shares for shares of a non-Canadian corporation on a tax-deferred basis. It is possible that the tax proposals described in this announcement, if enacted into law, could, from the time any such change takes effect, allow you to exchange exchangeable shares for common stock on a tax-deferred basis. However, no specifics have been announced regarding what the requirements for such treatment may be. BECAUSE OF THE EXISTENCE OF CERTAIN CALL RIGHTS HELD BY CALLCO WHICH GIVE CALLCO THE OVERRIDING RIGHT TO PURCHASE YOUR EXCHANGEABLE SHARES UPON A REDEMPTION (INCLUDING A RETRACTION) BY EXCHANGING A SHARE OF COMMON STOCK FOR EACH EXCHANGEABLE SHARE AS WELL AS CERTAIN RIGHTS OF HOLDERS OF EXCHANGEABLE SHARES 7 TO FORCE THE EXCHANGE OF EXCHANGEABLE SHARES WITH DUKE ENERGY FOR COMMON STOCK UPON THE OCCURRENCE OF THE LIQUIDATION, DISSOLUTION OR WINDING-UP OF EXCHANGECO OR DUKE ENERGY, YOU CANNOT CONTROL WHETHER YOU WILL RECEIVE COMMON STOCK BY WAY OF A REDEMPTION (INCLUDING A RETRACTION) OF YOUR EXCHANGEABLE SHARES BY EXCHANGECO OR BY WAY OF PURCHASE OF THE EXCHANGEABLE SHARES BY DUKE ENERGY OR CALLCO. AS DESCRIBED ABOVE, THE CANADIAN FEDERAL INCOME TAX CONSEQUENCES OF A REDEMPTION (INCLUDING A RETRACTION) DIFFER FROM THOSE OF A PURCHASE. DISPOSITION OF EXCHANGEABLE SHARES OTHER THAN ON REDEMPTION OR EXCHANGE A disposition or deemed disposition of your exchangeable shares, other than on the redemption or exchange of your exchangeable shares, will generally result in a capital gain (or capital loss) to the extent that the proceeds of disposition, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base to you immediately before the disposition. The taxation of capital gains and capital losses is described below. ACQUISITION AND DISPOSITION OF THE COMMON STOCK The cost of the common stock received on a retraction, redemption or exchange of exchangeable shares will be equal to the fair market value of the common stock at the time of that event, and will be averaged with the adjusted cost base of any other shares of common stock held by you at that time as capital property (other than common stock considered to have been continually held by you since 1971) for the purpose of determining the adjusted cost base of your common stock. A disposition or deemed disposition of the common stock by you will generally result in a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base to you of such shares immediately before the disposition. The taxation of capital gains and capital losses is described below. DIVIDENDS ON EXCHANGEABLE SHARES If you are an individual, dividends received or deemed to be received on the exchangeable shares will be included in computing your income, and will be subject to the gross-up and dividend tax credit rules normally applicable to taxable dividends received from a corporation resident in Canada. Subject to the discussion below, if you are a corporation, other than a "specified financial institution" as defined in the Canadian Income Tax Act, dividends received or deemed to be received on the exchangeable shares normally will be included in your income and deductible in computing your taxable income. The exchangeable shares will be "term preferred shares," as defined in the Canadian Income Tax Act. Consequently, if you are a "specified financial institution," as defined in the Canadian Income Tax Act, a dividend received or deemed to be received on a redemption of the exchangeable shares will be deductible in computing your taxable income only if: - you did not acquire the exchangeable shares in the ordinary course of carrying on your business; or - at the time the dividend is received, the exchangeable shares are listed on a prescribed stock exchange in Canada (which currently includes the Toronto Stock Exchange (TSE), on which it is expected that the exchangeable shares will be listed) and you, either alone or together with persons with whom you do not deal at arm's length, do not receive (or are not deemed to receive) dividends in respect of more than 10% of the issued and outstanding exchangeable shares. In addition, if you are a corporation and if we or any other person with whom we do not deal at arm's length (including Exchangeco) are a "specified financial institution" (for purposes of the Canadian 8 Income Tax Act) at the time that dividends are paid on the exchangeable shares, subject to the exemption described below, dividends received or deemed to be received by you will be included in your taxable income but will not be deductible by you in computing your taxable income. We have advised Canadian counsel that we will be a specified financial institution for purposes of the Canadian Income Tax Act immediately after our acquisition of Westcoast Energy. This denial of the dividend deduction will not apply if, at the time the dividends are received or deemed to be received by you, the exchangeable shares are listed on a prescribed stock exchange in Canada (which currently includes the TSE, on which it is expected that the exchangeable shares will be listed), we and Callco are "related" to Exchangeco for the purposes of the Canadian Income Tax Act and dividends are not paid to you (together with persons with whom you do not deal at arm's length or any trust or partnership of which you or any such person is a beneficiary or member) in respect of more than 10% of the issued and outstanding exchangeable share held by persons other than us and our affiliates. If you are a "private corporation," as defined in the Canadian Income Tax Act, or any other corporation resident in Canada and controlled or deemed to be controlled by or for the benefit of an individual or a related group of individuals, you may be liable under Part IV of the Canadian Income Tax Act to pay a refundable tax of 33 1/3% of any dividends received or deemed to be received on your exchangeable shares to the extent that these dividends are deductible in computing your taxable income. If you are throughout the relevant taxation year a "Canadian-controlled private corporation," as defined in the Canadian Income Tax Act, you may be liable to pay an additional refundable tax of 6 2/3% on dividends received or deemed to be received on your exchangeable shares that are not deductible in computing taxable income. DIVIDENDS ON THE COMMON STOCK Dividends on the common stock will be included in your income for the purposes of the Canadian Income Tax Act. If you are an individual, you will not be subject to the gross-up and dividend tax credit rules in the Canadian Income Tax Act applicable to dividends received from corporations resident in Canada. If you are a corporation, you will be required to include these dividends in computing your income and will not be entitled to deduct the amount of these dividends in computing your taxable income. If you are a "Canadian-controlled private corporation," as defined in the Canadian Income Tax Act, you may be liable to pay an additional refundable tax of 6 2/3% on such dividends. If there is United States non-resident withholding tax on any dividends you receive on the common stock, you will generally be eligible for foreign tax credit or deduction treatment where applicable under the Canadian Income Tax Act. TAXATION OF CAPITAL GAINS AND CAPITAL LOSSES One-half of any capital gain (the "taxable capital gain") realized by you on a disposition or deemed disposition of exchangeable shares or the common stock must be included in your income for the year of the disposition. One-half of any capital loss (the "allowable capital loss") realized by you may be deducted by you against taxable capital gains realized in the year of the disposition. Any allowable capital losses in excess of taxable capital gains in the year of disposition may be carried back up to three taxation years or forward indefinitely and deducted against net taxable capital gains in those other years to the extent and in the circumstances prescribed in the Canadian Income Tax Act. Capital gains realized by an individual or trust, other than certain trusts, may give rise to alternative minimum tax under the Canadian Income Tax Act. If you are a "Canadian-controlled private corporation," as defined in the Canadian Income Tax Act, you may be liable to pay an additional refundable tax of 6 2/3% on taxable capital gains. If you are a corporation, the amount of any capital losses arising from a disposition or deemed disposition of exchangeable shares may be reduced by the amount of any dividends received or deemed to have been received by you on the exchangeable shares to the extent and under circumstances prescribed 9 by the Canadian Income Tax Act. Similar rules may apply where you are a corporation that is a member of a partnership or a beneficiary of a trust that owns exchangeable shares or where a trust or partnership of which a corporation is a beneficiary or a member is a member of a partnership or a beneficiary of a trust that owns any of these shares. You should consult your own tax advisors if these rules may be relevant to you. FOREIGN PROPERTY INFORMATION REPORTING If you are a "specified Canadian entity" (as defined in the Canadian Income Tax Act), you may be required to file an information return relating to any "specified foreign property" (as defined in the Canadian Income Tax Act) owned by you, which would include the common stock, the exchangeable shares and certain exchange and voting rights relating thereto. You should consult you own advisors about whether you must comply with these rules with respect to the ownership of exchangeable shares or common stock. FOREIGN INVESTMENT ENTITY DRAFT LEGISLATION Draft legislation regarding the taxation of investments in "foreign investment entities" was released on August 2, 2001. In general, if the draft legislation applies, a holder of an interest in a foreign investment entity generally will be required to take into account in computing income changes in the value of that interest. A corporation is not a foreign investment entity if the "carrying value" of all of its "investment property" is not greater than one-half of the "carrying value" of all of its property or if its principal business is not an "investment business" within the meaning of those terms in the draft legislation. We believe that we are not currently a "foreign investment entity" within the meaning of the draft legislation, however, no assurances can be given in this regard or as to our status in the future. In any event, in general, these proposed rules will not apply to the common stock or the exchangeable shares so long as the common stock is widely held and actively traded and listed on a prescribed stock exchange, unless it is reasonable to conclude that you had a tax avoidance motive for the acquisition of the shares in the terms contemplated by the draft legislation. It was originally announced that the draft legislation would be applicable for taxation years commencing after 2001. However, on December 17, 2001, the Department of Finance (Canada) issued a press release announcing that the effective date for the proposed rules will be delayed one year, generally to take effect for taxation years commencing after 2002, in order to allow for a full consideration of submissions on the draft legislation. It is possible that the draft legislation may be amended before it is enacted in final form. U.S. FEDERAL INCOME TAX CONSIDERATIONS In the opinion of Vinson & Elkins L.L.P., our United States counsel, the following is an accurate summary of the principal United States federal income tax considerations under the United States Internal Revenue Code of 1986, as amended (the "Code"), generally applicable to you if you are a holder of exchangeable shares and you are not: - a citizen or resident of the United States; - a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States or of any political subdivision thereof; - an estate, the income of which is subject to United States federal income taxation regardless of its source; or - a trust if a United States court is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust. 10 This summary does not discuss all United States federal income tax considerations that may be relevant to you in light of your particular circumstances or if you are subject to special treatment under the Code. This summary is applicable to you only if you hold exchangeable shares as capital assets and does not consider your tax treatment if you hold exchangeable shares through a partnership or other pass-through entity. Furthermore, this summary does not discuss any aspects of foreign, state or local taxation. This summary is based on current provisions of the Code, existing, temporary and proposed regulations promulgated under the Code and administrative and judicial interpretations of the Code, all of which are subject to change, possibly with retroactive effect. No advance income tax ruling has been sought or obtained from the Internal Revenue Service (the "IRS") regarding the tax consequences of the transactions described herein. YOU ARE ADVISED TO CONSULT YOUR TAX ADVISORS WITH RESPECT TO THE UNITED STATES FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE TRANSACTIONS DESCRIBED HEREIN. SALE OR EXCHANGE OF EXCHANGEABLE SHARES You generally will not be subject to United States federal income tax on any gain realized on the sale or exchange of exchangeable shares, including the exchange of exchangeable shares for common stock, unless the gain is effectively connected with your United States trade or business or, if you are an individual, you are present in the United States for 183 days or more during the taxable year of disposition and certain other conditions are satisfied. DIVIDENDS ON THE COMMON STOCK Dividends paid to you as a holder of common stock generally will be subject to withholding of United States federal income tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) unless the dividend is effectively connected with the conduct of your trade or business within the United States (or if a tax treaty applies, is attributable to your United States permanent establishment), in which case the dividend will be taxed at ordinary United States federal income tax rates. If you are a corporation, such effectively connected income may also be subject to an additional "branch profits tax." You will be required to satisfy certain certification requirements to claim treaty benefits or otherwise claim a reduction of, or exemption from, the withholding tax described above. SALE OR EXCHANGE OF COMMON STOCK You generally will not be subject to United States federal income tax on any gain realized on the sale or exchange of shares of common stock unless: - the gain is effectively connected with your United States trade or business; - you are an individual and you are present in the United States for 183 days or more during the taxable year of disposition and certain other conditions are satisfied; or - you have owned (actually or constructively) more than 5% of our outstanding common stock. BACKUP WITHHOLDING AND INFORMATION REPORTING You are generally subject to information reporting requirements with respect to dividends paid by us to you and any tax withheld with respect to such dividends. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which you reside under the provisions of an applicable income tax treaty. You will be subject to backup withholding unless applicable certification requirements are met. Payment of the proceeds of a sale of shares of the common stock within the United States or through certain United States brokers is subject to both backup withholding and information reporting unless you as beneficial owner certify under penalties of perjury that you are not a United States person for purposes of the Code (and the payor does 11 not have actual knowledge or reason to know that you are a United States person) or otherwise establishes an exemption. Backup withholding tax is not a separate tax. Any amounts withheld under the backup withholding rules are generally allowable as a credit against your United States federal income tax liability (if any), which may entitle you to a refund, provided that the required information is furnished to the IRS. The discussion of United States federal income tax consequences set forth above is for general information only and does not purport to be a complete analysis or listing of all potential tax effects that may apply to you. You are strongly encouraged to consult your tax adviser to determine the particular tax consequences to you, including the application and effect of United States federal, state, local and foreign tax laws.
