(Face of Security continued on next page) -2- 3 OTHER TERMS: All terms used in this Security that are not defined in this Security but are defined in the Indenture referred to on the reverse of this Security shall have the meanings assigned to them in the Indenture. Section headings on the face of this Security are for convenience only and shall not affect the construction of this Security. "Business Day" means any day that is not a Saturday, a Sunday or a day on which the New York Stock Exchange (or, if different, the principal U.S. national securities market in which any of the BULS Stocks is then quoted or traded), or on which banking institutions in The City of New York, generally, are authorized or obligated by law, regulation or executive order to close. "Closing Price" means, with respect to any BULS Stock on any day, the closing sale price or last reported sale price, regular way, for that BULS Stock on a per-share basis (i) on the principal U.S. national securities exchange on which that BULS Stock is listed for trading on such day, (ii) if that BULS Stock is not listed on any national securities exchange, on the Nasdaq National Market System on such day or (iii) if that BULS Stock is not quoted in the Nasdaq National Market System on such day, on such other U.S. national market system that is the primary U.S. national market for the trading of that BULS Stock; provided, however, that, if that BULS Stock is not listed or quoted as described in clause (i), (ii) or (iii) above, the Closing Price with respect to that BULS Stock will be the average, as determined by the Calculation Agent, of the bid prices for that BULS Stock obtained from as many dealers in that BULS Stock selected by the Calculation Agent (which may include the Calculation Agent or any affiliate of such agent or of the Company) as will make such bid prices available to the Calculation Agent (provided that the number of such dealers need not exceed three). "Default Amount" means, on any day, an amount, in U.S. dollars equal to the cost of having a Qualified Financial Institution (selected as provided below) expressly assume the due and punctual payment of the principal of this Security, and the performance or observance of every covenant hereof and of the Indenture on the part of the Company to be performed or observed with respect to this Security (or to undertake other obligations providing substantially equivalent economic value to the Holder of this Security as the Company's obligations hereunder). Such cost will equal (i) the lowest amount that a Qualified Financial Institution would charge to effect such assumption (or undertaking) plus (ii) the reasonable expenses (including reasonable attorneys' fees) incurred by the Holder of this Security in preparing any documentation necessary for such assumption (or undertaking). During the Default Quotation Period, each of the Holder of this Security and the Company may request a Qualified Financial Institution to provide a quotation of the amount it would charge to effect such assumption (or undertaking) and notify the other in writing of such quotation. The amount referred to in clause (i) of this paragraph will equal the lowest (or, if there is only one, the only) quotation so obtained, and as to which notice is so given, during (Face of Security continued on next page) -3- 4 the Default Quotation Period; provided that, with respect to any quotation, the party not obtaining such quotation may object, on reasonable and significant grounds, to the effectuation of such assumption (or undertaking) by the Qualified Financial Institution providing such quotation and notify the other party in writing of such grounds within two Business Days after the last day of the Default Quotation Period, in which case such quotation will be disregarded in determining the Default Amount. The "Default Quotation Period" will be the period beginning on the day the Default Amount first becomes due and payable and ending on the third Business Day after such due day, unless no such quotation is so obtained, or unless every such quotation so obtained is objected to within five Business Days after such due day as provided above, in which case the Default Quotation Period will continue until the third Business Day after the first Business Day on which prompt notice is given of such a quotation as provided above, unless such quotation is objected to as provided above within five Business Days after such first Business Day, in which case the Default Quotation Period will continue as provided in this sentence. Notwithstanding the foregoing, if the Default Quotation Period (and the subsequent two Business Day objection period) has not ended prior to the Determination Date, then the Default Amount will equal the Principal Amount. "Determination Date" means the third Business Day prior to May [ ], 2003; provided, however, that if a Market Disruption Event occurs or is continuing on the third prior Business Day, the Determination Date will be the first following Business Day on which the Calculation Agent determines that a Market Disruption Event does not occur and is not continuing; provided, further, that in no event will the Determination Date be later than May [ ], 2003 or, if May [ ], 2003 is not a Business Day, later than the first Business Day after May [ ], 2003. "Distribution Property" means securities, cash and/or other property distributed in respect of the relevant BULS Stock and, in the case of a Spin-Off Event (as defined in Section 10), includes such BULS Stock. "Ex-Dividend Date" for any dividend or other distribution in respect of a BULS Stock shall mean the first day on which that BULS Stock trades without the right to receive such dividend or other distribution. "Market Disruption Event" means, with respect to any BULS Stock, (i) a suspension, absence or material limitation of trading of that BULS Stock in the primary U.S. national market for that BULS Stock for more than two hours of trading or during the one-half hour period preceding the close of trading in such market, (ii) a suspension, absence or material limitation of trading in option contracts related to that BULS Stock, if available, in the primary U.S. national market for such contracts for more than two hours of trading or during the one-half hour period preceding the close of trading in such market or (iii) that BULS Stock does not trade on what was the primary U.S. national market for that BULS Stock, in each case (i), (ii) and (iii) as determined by the Calculation Agent in its sole (Face of Security continued on next page) -4- 5 discretion; provided, however, that no such event described in clause (i), (ii) or (iii) will be a Market Disruption Event unless the Calculation Agent also determines that such event materially interferes with the ability of the Company or any of its affiliates to unwind all or a material portion of any hedge that any of them effects with respect to this Security. For purposes of determining whether a Market Disruption Event has occurred, (a) a limitation on the hours or numbers of days of trading in the relevant market will not constitute a Market Disruption Event if it results from an announced change in the regular business hours of such market, (b) a decision to permanently discontinue trading in the relevant option contracts will not constitute a Market Disruption Event, (c) a suspension or limitation of trading in option contracts related to a BULS Stock, if available, in the primary U.S. national market for such contracts, by reason of (1) a price change exceeding limits set by such market, (2) an imbalance of orders relating to such contracts or (3) a disparity in bid and ask quotes relating to such contracts, will, in each case (1), (2) and (3), constitute a suspension or material limitation of trading in option contracts related to that BULS Stock and (d) an "absence of trading" in the primary U.S. national market on which option contracts related to a BULS Stock are traded will not include any time when such market is itself closed for trading under ordinary circumstances. References to "BULS Stock" in this paragraph will also be deemed to refer to any Distribution Property consisting of securities. "Qualified Financial Institution" means, at any time, a financial institution organized under the laws of any jurisdiction in the United States of America, Europe or Japan that at such time has outstanding debt obligations with a stated maturity of one year or less from the date of issue and rated A-1 or higher by Standard & Poor's Ratings Group (or any successor) or P-1 or higher by Moody's Investors Service, Inc. (or any successor) or, in either case, such other comparable rating, if any, then used by such rating agency. "Stated Maturity Date" means May [ ], 2003 or, if such day is not a Business Day, the next succeeding Business Day; provided, however, that if the third Business Day preceding May [ ], 2003 is not the Determination Date, the Stated Maturity Date will be the third Business Day succeeding the Determination Date; provided, further, that in no event will the Stated Maturity Date be later than the third Business Day after May [ ], 2003 or, if May [ ], 2003 is not a Business Day, later than the fourth Business Day after May [ ], 2003. "Trade Date" means May [ ], 2001. ----------------------- 1. Promise to Pay Principal UBS AG, a corporation duly organized and existing under the laws of Switzerland (herein called the "Company", which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay (or cause to be paid) to Cede & Co., as nominee for The Depository Trust Company, or registered (Face of Security continued on next page) -5- 6 assigns, the principal sum calculated as provided under "Principal Amount" and elsewhere on the face of this Security, on the Stated Maturity Date. 2. Payment of Interest The principal of this Security shall not bear interest. 3. Principal Amount The principal of this Security that becomes due and payable on the Stated Maturity Date shall be the cash amount that must be paid to redeem this Security as provided above under "Principal Amount." The principal of this Security that becomes due and payable upon acceleration of the Maturity hereof after an Event of Default has occurred pursuant to the Indenture shall be the Default Amount. When the principal referred to in either of the two preceding sentences has been paid as provided herein (or such payment has been made available), the principal of this Security shall be deemed to have been paid in full, whether or not this Security shall have been surrendered for payment or cancellation. References to the payment of the principal of this Security on any day shall be deemed to mean the payment of cash that is payable on such day as provided in this Security. Notwithstanding the foregoing, solely for the purpose of determining whether any consent, waiver, notice or other action to be given or taken by Holders of Securities pursuant to the Indenture has been given or taken by Holders of Outstanding Securities in the requisite aggregate principal amount, the principal amount of this Security will be deemed to equal the Face Amount. This Security shall cease to be Outstanding as provided in the definition of such term in the Indenture or when the principal of this Security shall be deemed to have been paid in full as provided above. 4. Anti-dilution Adjustment The Calculation Agent shall adjust the Number of Shares of any BULS Stock as provided in this Security in respect of each event for which adjustment is required under Sections 5 through 10 (and not in respect of any other event). If more than one such event occurs, the Calculation Agent shall adjust the Number of Shares as so provided for each such event, sequentially, in the order in which such events occur, and on a cumulative basis. If the Number of Shares of any BULS Stock is adjusted pursuant to Section 10 so as to consist of amounts of more than one type of property, then the Final Stock Price shall equal the sum of the respective Closing Prices or other values for all such amounts of property on the Determination Date, determined as provided in Section 10. The Calculation Agent shall make all adjustments no later than the Determination Date. Notwithstanding any provision of this Security, if an event for which adjustment is required under Sections 5 through 10 occurs, the Calculation Agent may make the adjustment and any related determinations and calculations in a manner that differs from (Face of Security continued on next page) -6- 7 that specified in this Security as necessary to achieve an equitable result. Upon written request by the Holder to the Calculation Agent, the Calculation Agent will provide the Holder with such information about adjustments made pursuant to this Security as such agent determines is appropriate. 5. Stock Splits If a BULS Stock is subject to a stock split, then at the opening of business on the first day on which that BULS Stock trades without the right to receive the stock split, the Calculation Agent will adjust the Number of Shares of that BULS Stock to equal the sum of the Number of Shares in effect immediately prior to such adjustment plus the product of (i) the number of new shares issued in the stock split with respect to one share of that BULS Stock and (ii) the Number of Shares in effect immediately prior to such adjustment. The Number of Shares will not be adjusted, however, unless such first day occurs after the Trade Date and on or before the Determination Date. 6. Reverse Stock Splits If a BULS Stock is subject to a reverse stock split, then once the reverse stock split becomes effective, the Calculation Agent will adjust the Number of Shares of that BULS Stock to equal the product of the Number of Shares in effect immediately prior to such adjustment and the quotient of (i) the number of outstanding shares of the relevant BULS Stock resulting from the reverse stock split divided by (ii) the number of shares of the relevant BULS Stock outstanding immediately before the reverse stock split becomes effective. The Number of Shares will not be adjusted, however, unless the reverse stock split becomes effective after the Trade Date and on or before the Determination Date. 7. Stock Dividends If a BULS Stock is subject to a stock dividend that is given ratably to all holders of that BULS Stock, then at the opening of business on the Ex-Dividend Date, the Calculation Agent will adjust the Number of Shares of that BULS Stock to equal the Number of Shares in effect immediately prior to such adjustment plus the product of (i) the number of shares issued in the BULS Stock dividend with respect to one share of the relevant BULS Stock and (ii) the Number of Shares in effect immediately prior to such adjustment. The Number of Shares will not be adjusted, however, unless such Ex-Dividend Date occurs after the Trade Date and on or before the Determination Date. 8. Other Dividends and Distributions There will be no adjustments to the Number of Shares of a BULS Stock to reflect dividends or other distributions paid with respect to that BULS Stock other than (i) stock dividends as provided in Section 7, (ii) issuances of transferable rights or warrants as (Face of Security continued on next page) -7- 8 provided in Section 9, (iii) dividends or other distributions constituting Spin-Off Events as provided in Section 10 and (iv) Extraordinary Dividends as provided in this Section 8. A dividend or other distribution with respect to a BULS Stock will be deemed to be an "Extraordinary Dividend" if the per share value of such dividend or other distribution exceeds the per share value of the immediately preceding dividend or distribution with respect to that BULS Stock, if any, that is not an Extraordinary Dividend by an amount equal to at least 10% of the Closing Price of that BULS Stock on the Business Day immediately preceding the Ex-Dividend Date for such Extraordinary Dividend. If an Extraordinary Dividend occurs with respect to a BULS Stock, the Calculation Agent will adjust the Number of Shares to equal the product of (a) the Number of Shares in effect immediately prior to such adjustment and (b) a fraction, the numerator of which is the Closing Price of the relevant BULS Stock on the Business Day immediately preceding the Ex-Dividend Date and the denominator of which is the amount by which such Closing Price of that BULS Stock exceeds the Extraordinary Dividend Amount. The "Extraordinary Dividend Amount" with respect to an Extraordinary Dividend for a BULS Stock will equal (1) in the case of cash dividends or other distributions that constitute regular quarterly dividends, the amount per share of such Extraordinary Dividend minus the amount per share of the immediately preceding dividend or distribution with respect to that BULS Stock, if any, that is not an Extraordinary Dividend or (2) in the case of cash dividends or other distributions that do not constitute regular quarterly dividends, the amount per share of such Extraordinary Dividend. To the extent an Extraordinary Dividend is not paid in cash, the value of the non-cash component will be determined by the Calculation Agent. A distribution on a BULS Stock that constitutes a stock dividend, an issuance of transferable rights or warrants or a Spin-Off Event and also an Extraordinary Dividend will result only in an adjustment to the Number of Shares pursuant to Section 7, 9 or 10, as applicable. The Number of Shares will not be adjusted pursuant to this Section 8 unless the Ex-Dividend Date for the Extraordinary Dividend occurs after the Trade Date and on or before the Determination Date. 9. Transferable Rights and Warrants If a BULS Stock Issuer issues transferable rights or warrants to all holders of its BULS Stock to subscribe for or purchase its BULS Stock at an exercise price per share that is less than the Closing Price of its BULS Stock on the Business Day immediately before the Ex-Dividend Date for such issuance, then the Calculation Agent will adjust the Number of Shares of that BULS Stock by multiplying the Number of Shares in effect immediately prior to such adjustment by a fraction, the numerator of which is the number of shares of the relevant BULS Stock outstanding at the close of business on the day before such Ex-Dividend Date plus the number of additional shares of that BULS Stock offered for subscription or purchase under such transferable rights or warrants, and the denominator of which is the number of shares of that BULS Stock outstanding at the close of business on the day before such Ex-Dividend Date plus the number of additional shares of that BULS Stock that the aggregate offering price of the total number of shares of the BULS Stock so offered for subscription or purchase would purchase at the Closing Price of the BULS Stock on the (Face of Security continued on next page) -8- 9 Business Day immediately before such Ex-Dividend Date, with such number of additional shares being determined by multiplying the total number of shares so offered by the exercise price of such transferable rights or warrants and dividing the resulting product by the Closing Price of the BULS Stock on the Business Day immediately before such Ex-Dividend Date. The Number of Shares will not be adjusted, however, unless such Ex-Dividend Date occurs after the Trade Date and on or before the Determination Date. 10. Reorganization Events If (i) any reclassification or other change of any BULS Stock occurs, (ii) the BULS Stock Issuer has been subject to a merger, consolidation or other combination and either is not the surviving entity or is the surviving entity but all its outstanding BULS Stock is exchanged for or converted into Distribution Property, (iii) any statutory share exchange involving the outstanding BULS Stock and the securities of another entity occurs (other than in a transaction described in clause (ii) above), (iv) any BULS Stock Issuer sells or otherwise transfers its property and assets as an entirety or substantially as an entirety to another entity, (v) any BULS Stock Issuer issues to all holders of its BULS Stock equity securities of an issuer other than the BULS Stock Issuer (other than in a transaction described in clause (i), (ii), (iii) or (iv) above) (a "Spin-Off Event"), (vi) the BULS Stock Issuer is liquidated, dissolved or wound up or is subject to a proceeding under any applicable bankruptcy, insolvency or other similar law, or (vii) an issuer completes a tender or exchange offer for all the outstanding BULS Stock of a BULS Stock Issuer (any such event in clauses (i) through (vii), a "Reorganization Event"), then the Calculation Agent will adjust the Number of Shares of the applicable BULS Stock so that the Number of Shares of that BULS Stock consists of the respective amounts of each type of Distribution Property distributed in such Reorganization Event in respect of the Number of Shares as in effect immediately prior to such adjustment, taken together. Notwithstanding the foregoing, however, the Calculation Agent will not make any adjustment for a Reorganization Event unless the event becomes effective -- or, if the event is a Spin-Off Event, unless the Ex-Dividend Date for the Spin-Off Event occurs -- after the Trade Date and on or before the Determination Date. If the Calculation Agent determines that the Distribution Property so distributed consists of more than one type of property, the Calculation Agent will determine the respective amounts of such types that will comprise the adjusted Number of Shares so that the value of each such amount bears the same relationship to the total value of all such amounts as the value of the corresponding component type of Distribution Property so distributed bears to the total value of all Distribution Property so distributed. The Calculation Agent will determine the value of each component type of Distribution Property, using the Closing Price for any such type consisting of securities and such other method as it considers reasonable for any other type. If a holder of the Stock may elect to receive different types or combinations of types of Distribution Property in the Reorganization Event, the Distribution Property will be deemed to include the types and amounts thereof distributed to a holder that makes no election. If a Reorganization Event occurs and as a result the (Face of Security continued on next page) -9- 10 Number of Shares is adjusted to consist of Distribution Property, the Calculation Agent will make further adjustments for subsequent events that affect such Distribution Property or any component type thereof, to the same extent that it would make adjustments if the Stock were outstanding and were affected by the same kinds of events. If at any time another Person becomes the successor to a BULS Stock Issuer, as determined by the Calculation Agent, such successor Person shall thereupon be deemed to be a BULS Stock Issuer for all purposes of this Security. If at any time the Number of Shares consists of Distribution Property, as determined by the Calculation Agent, then all references in this Security to "BULS Stock" shall thereupon be deemed to mean such Distribution Property and all references in this Security to a "share of BULS Stock" shall thereupon be deemed to mean a comparable unit of each type of property comprising such Distribution Property, as determined by the Calculation Agent. 11. Minimum Adjustments Notwithstanding the foregoing, no adjustment will be required in respect of any event specified in Sections 5 through 9 unless such adjustment would result in a change of at least 0.1% in the Number of Shares of any BULS Stock. The exchange rate resulting from any adjustment shall be rounded up or down, as appropriate to the nearest ten-thousandth, with five hundred-thousandths being rounded upward. 12. Role of Calculation Agent The Calculation Agent will be solely responsible for all determinations and calculations regarding the Default Amount; whether a Market Disruption Event has occurred and whether, and if so the dates to which, the Determination Date and Stated Maturity Date are to be postponed; adjustment of the Number of Shares of any BULS Stock, including whether any event has occurred for which adjustment is required and as to the amounts, types and values of property comprising any Distribution Property and the Number of Shares; the Closing Price or other value of the BULS Stocks or any other property; as to the amounts and types of property deliverable or payable in exchange for this Security on the Stated Maturity Date; and all such other matters as may be specified elsewhere herein as matters to be determined by the Calculation Agent. The Calculation Agent shall make all such determinations and calculations in its sole discretion, and absent manifest error all determinations and calculations made by the Calculation Agent shall be final and binding on the Company, the Holder and all other Persons having an interest in this Security, without liability on the part of the Calculation Agent. The Company shall take such action as shall be necessary to ensure that there is at all relevant times a financial institution serving as the Calculation Agent hereunder. The Company may, in its sole discretion at any time and from time to time, upon written notice to the Trustee, but without notice to the Holder of this Security, terminate the appointment of (Face of Security continued on next page) -10- 11 any Person serving as the Calculation Agent and appoint another Person (including any Affiliate of the Company) to serve as such agent. Insofar as this Security provides for the Calculation Agent to obtain prices or other information from any institution or other source, the Calculation Agent may do so from any source or sources of the kind contemplated or otherwise permitted hereby notwithstanding that any one or more of such sources are such agent, Affiliates of such agent or Affiliates of the Company. 13. Tax Characterization By its purchase of this Security, the Holder, on behalf of itself and any other Person having a beneficial interest in this Security, hereby agrees with the Company (in the absence of an administrative determination or judicial ruling to the contrary) to characterize this Security for all U.S. federal income tax purposes as a pre-paid cash-settled forward contract with respect to the BULS Stocks. Notwithstanding the foregoing, the Company shall not be obligated to segregate or otherwise set aside any funds, and no act or omission on the part of the Company or any other Person, and no event or circumstance, shall give rise to any default or Event of Default under this Security or the Indenture by reason of any provision of this Section 13. 14. Payment Payment of any amount payable on this Security will be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Payment will be made to an account designated by the Holder (in writing to the Company and the Trustee on or before the Determination Date) and acceptable to the Company or, if no such account is designated and acceptable as aforesaid, at the office or agency of the Company maintained for that purpose in The City of New York, provided, however, that payment at Maturity shall be made only upon surrender of this Security at such office or agency (unless the Company waives surrender). Notwithstanding the foregoing, if this Security is a Global Security, any payment may be made pursuant to the Applicable Procedures of the Depositary as permitted in said Indenture. 15. Holidays Notwithstanding any provision of this Security or of the Indenture, if any payment of principal would otherwise be due on this Security on a day (the "Specified Day") that is not a Business Day, such payment may be made (or such principal may be made available for payment) on the next succeeding Business Day with the same force and effect as if such payment were made on the Specified Day. The provisions of this Section shall apply to this Security in lieu of the provisions of Section 114 of the Indenture. (Face of Security continued on next page) -11- 12 16. Reverse of this Security Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place. 17. Certificate of Authentication Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. (Face of Security continued on next page) -12- 13 IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed. UBS AG By____________________________ Name: Robert B. Mills Title: Managing Director By____________________________ Name: Robert C. Dinerstein Title: Managing Director This is one of the Securities of the series designated herein and referred to in the Indenture. Dated: U.S. BANK TRUST NATIONAL ASSOCIATION, AS TRUSTEE By_________________________________ Authorized Signatory 14 (Reverse of Security) This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities") issued and to be issued in one or more series under an Indenture, dated as of November 21, 2000 (herein called the "Indenture", which term shall have the meaning assigned to it in such instrument), between the Company and U.S. Bank Trust National Association, as Trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Insofar as the provisions of the Indenture may conflict with the provisions set forth on the face of this Security, the latter shall control for purposes of this Security. This Security is one of the series designated on the face hereof, limited to an aggregate initial offering price not to exceed $50,000,000 (or the equivalent thereof in any other currency or currencies or currency units), which amount may be increased at the option of the Company if in the future it determines that it may wish to sell additional Securities of this series. References herein to "this series" mean the series designated on the face hereof. Payments under the Securities will be made without withholding or deduction for or on account of any present or future tax, duty, assessment or governmental charge ("Taxes"), imposed upon or as a result of such payments by Switzerland or any jurisdiction in which a branch of the Company through which the Securities are issued is located (or any political subdivision or taxing authority thereof or therein) (a "Relevant Jurisdiction"), unless required by law. To the extent any such Taxes are so levied or imposed, the Company will, subject to the exceptions and limitations set forth in Section 1007 of the Indenture, pay such additional amounts ("Additional Amounts") to the Holder of any Security who is not a resident of the Relevant Jurisdiction as may be necessary in order that every net payment of the principal of such Security and any other amounts payable on such Security, after withholding for or on account of such Taxes imposed upon or as a result of such payment, will not be less than the amount provided for in such Security to be then due and payable. If at any time as a result of any change in or amendment to the laws or regulations of a Relevant Jurisdiction affecting taxation, or a change in any application or interpretation of such laws or regulations (including the decision of any court or tribunal) either generally or in relation to any particular Securities, which change, amendment, application or interpretation becomes effective on or after the Trade Date in making any payment of, or in respect of, the principal amount of the Securities, the Company would be required to pay any Additional Amounts with respect thereto, then the Securities will be redeemable upon not less than 10 nor more than 60 days' notice by mail, at any time (Reverse of Security continued on next page) -14- 15 thereafter, in whole but not in part, at the election of the Company as provided in the Indenture at a redemption price determined by the Calculation Agent in a manner reasonably calculated to preserve the relative economic position of the Company and the Holders of Outstanding Securities. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected (considered together as one class for this purpose). The Indenture also contains provisions (i) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected under the Indenture (considered together as one class for this purpose), on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and (ii) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture (with each such series considered separately for this purpose), on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof on or after the respective due dates expressed herein. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of this Security as herein provided.
