"Weighted Determined Performance Rate" shall mean, for each Calculation Date, the Determined Performance Rate on such Calculation Date multiplied by the Basket Weight of the Basket Stock used to determine the Determined Performance Rate.

Other capitalized terms used but not defined herein have the meanings given in the Indenture.

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 the Indenture, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof and will initially be offered in the principal amount of $5,750,000. The Company may, without the consent of the Holders, issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions and with the same CUSIP number as this Security.

On each Calculation Date, the Calculation Agent shall determine the Closing Price and the Performance Rate for each Basket Stock in the Basket on such Calculation Date. Based on such determinations, the Calculation Agent shall determine the Determined Performance Rate and the Weighted Determined Performance Rate for such Calculation Date. For all Calculation Dates occurring after such Calculation Date, the Basket Stock whose Performance Rate was used to determine the Determined Performance Rate and the Weighted Determined Performance Rate for such Calculation Date shall be removed from the Basket and its Performance Rate will no longer be determined.

In the event a Calculation Date does not fall on an Exchange Business Day, such Calculation Date shall be the next succeeding Exchange Business Day, that, if the Calculation Date (as defined in Section 2.2) that is the Basket Return Determination Date does not fall on an Exchange Business Day, such Calculation Date shall be the immediately preceding Exchange Business Day.

On the final Calculation Date (the "Basket Return Determination Date"), the Calculation Agent shall determine the Basket Return Payment. The "Basket Return Payment" shall equal (a) (i) the sum of the Weighted Determined Performance Rates for all Calculation Dates multiplied by (b) the principal amount hereof. If the Basket Return Payment is determined to be zero or a negative number, then there shall be no Basket Return Payment.

If the Calculation Agent determines that any Calculation Date, including the Basket Return Determination Date, is a Market Disrupted Day, then such Calculation Date shall be postponed to the first succeeding Scheduled Trading Day that is not a Market Disrupted Day, unless each of the eight Scheduled Trading Days immediately following the originally scheduled Calculation Date is a Market Disrupted Day. In such case, (A) such eighth Scheduled Trading Day shall be deemed to be the Calculation Date, notwithstanding the fact that such day is a Market Disrupted Day, and (B) the Calculation Agent shall make the determinations required to be made under Sections 2.1 and 2.2 on such eighth Scheduled Trading Day in accordance with the formula for and method of calculating the Closing Prices, Performance Rates, Determined Performance Rates, Weighted Determined Performance Rates and, if applicable, the Basket Return Payment as provided herein. If, as a result of a Market Disruption Event, the Calculation Agent is unable to make a required determination with respect to any Basket Stock, the Calculation Agent shall estimate, in good faith, the value of such Basket Stock for purposes of determining the Closing Price thereof or make any other necessary determination using a good faith estimate. In the event the Basket Return Determination Date is postponed pursuant to

this Section 2.3, the Maturity Date shall be postponed to the date that is the third Exchange Business Day immediately following the actual Basket Return Determination Date.

The Calculation Agent shall adjust the Initial Price for a Basket Stock as provided herein in respect of each event for which adjustment is required under Sections 3.2 through 3.6 with respect to such Basket Stock (and not in respect of any other event). If more than one such event occurs with respect to a Basket Stock, the Calculation Agent shall adjust the Initial Price for such Basket Stock as so provided for each such event, sequentially, in the order in which such events occur, and on a cumulative basis. The Initial Price for each Basket Stock will be subject, independently and separately, to the adjustments described in Sections 3.2 through 3.6 with respect to the events that affect such Basket Stock. There will be no adjustments to the Initial Price for a Basket Stock to reflect dividends or other distributions paid with respect to such Basket Stock other than (i) stock dividends as provided in Section 3.3, (ii) Extraordinary Dividends as provided in Section 3.5 and (iii) issuances of transferable rights or warrants as provided in Section 3.6.

For purposes of this Article III, "prior Initial Price" refers to the Initial Price in effect immediately prior to the event giving rise to the adjustment.

The Company shall notify the Holder of any such adjustment made within a reasonable time after such adjustment is made.

If a Basket Stock is subject to a stock split, then at the opening of business on the first day on which such Basket Stock trades without the right to receive the stock split, the Calculation Agent will adjust the Initial Price by dividing the prior Initial Price by the number equal to (i) the number of shares of the Basket Stock outstanding immediately after the stock split divided by (ii) the number of shares of the Basket Stock outstanding immediately before the stock split. The Initial Price will not be adjusted, however, unless such first day occurs after the Trade Date and on or before the Calculation Date for which the Performance Rate of such Basket Stock will be determined.

If a Basket Stock is subject to a stock dividend that is given ratably to all holders of such Basket Stock, then at the opening of business on the Ex-Dividend Date, the Calculation Agent will adjust the Initial Price by dividing the prior Initial Price by the number equal to (i) the number of shares of the Basket Stock outstanding immediately after the stock dividend divided by (ii) the number of shares of the Basket Stock outstanding immediately before the stock dividend. The Initial Price will not be adjusted, however, unless such Ex-Dividend Date occurs after the Trade Date and on or before the Calculation Date for which the Performance Rate of such Basket Stock will be determined.

If a Basket Stock is subject to a reverse stock split, then once the reverse stock split becomes effective, the Calculation Agent will adjust the Initial Price by multiplying the prior Initial Price by the number equal to (i) the number of shares of the Basket Stock outstanding immediately before the reverse stock split divided by (ii) the number of shares of the Basket Stock outstanding immediately after the reverse stock split. The Initial Price will not be adjusted, however, unless the reverse stock split becomes effective after the Trade Date and on or before the Calculation Date for which the Performance Rate of such Basket Stock will be determined.

If an Extraordinary Dividend occurs with respect to a Basket Stock, the Calculation Agent will adjust the Initial Price to equal the product of (a) the prior Initial Price and (b) a fraction, the numerator of which is the amount by which the Closing Price of such Basket Stock exceeds the Extraordinary Dividend Amount on the Business Day immediately preceding the Ex-Dividend Date and the denominator of which is such Closing Price. For purposes of the foregoing, the "Extraordinary Dividend Amount" with respect to an Extraordinary Dividend for a Basket 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 such Basket 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 Basket Stock that constitutes a stock dividend or an issuance of transferable rights or warrants and also constitutes an Extraordinary Dividend will result only in an adjustment to the Initial Price for such Basket Stock pursuant to Section 3.3 or 3.6 as applicable. A distribution on a Basket Stock that constitutes a Spin-Off Event and also constitutes an Extraordinary Dividend will result only in an adjustment pursuant to Section 4.1 and the Initial Price will not be adjusted. The Initial Price will not be adjusted pursuant to this Section 3.5 unless the Ex-Dividend Date for the Extraordinary Dividend occurs after the Trade Date and on or before the Calculation Date for which the Performance Rate of such Basket Stock will be determined.

If a Basket Stock Issuer issues transferable rights or warrants to all holders of its Basket Stock to subscribe for or purchase such Basket Stock at an exercise price per share less than the Closing Price of such Basket Stock on the Business Day immediately before the Ex-Dividend Date for such issuance, then the Calculation Agent will adjust the Initial Price for such Basket Stock by multiplying the prior Initial Price by a fraction, the numerator of which is the number of shares of such Basket Stock outstanding at the close of business on the day before such Ex-Dividend Date plus the number of additional shares of such Basket Stock that the aggregate offering price of the total number of shares of such Basket Stock so offered for subscription or purchase would purchase at the Closing Price of such Basket Stock on the 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 such Basket Stock on the Business Day immediately before such Ex-Dividend Date and the denominator of which is the number of shares of such Basket Stock outstanding at the close of business on the day before such Ex-Dividend Date plus the number of additional shares of such Basket Stock offered for subscription or purchase under such transferable rights or warrants. The Initial Price will not be adjusted, however, unless such Ex-Dividend Date occurs after the Trade Date and on or before the Calculation Date for which the Performance Rate of such Basket Stock will be determined.

In the event a Reorganization Event occurs with respect to a Basket Stock, the Calculation Agent will adjust the method of calculation of the Closing Price for such Basket Stock so that it equals the value of the respective amounts of each type of Distribution Property deemed, for the purposes hereof, to be distributed in such Reorganization Event in respect of one share of such Basket Stock.

The Calculation Agent will determine in its sole discretion the value of each component type of Distribution Property, using the Closing Price on the relevant date for any such type consisting of securities and such other method as it considers reasonable for any other type. If a holder of the relevant Basket 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 method of determination of the Closing Price of a Basket Stock 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 as required hereby if the relevant Basket Stock were outstanding and were affected by the same kinds of events.

If at any time another Person becomes the successor to a Basket Stock Issuer, as determined by the Calculation Agent, such successor Person shall thereupon be deemed to be such Basket Stock Issuer for all purposes hereof. If at any time a Basket Stock consists of Distribution Property, as determined by the Calculation Agent, then all references herein to the corresponding "Basket Stock" shall thereupon be deemed to mean such Distribution Property, all references in this Security to a "share" of the corresponding Basket Stock shall thereupon be deemed to mean a comparable unit of each type of property comprising such Distribution Property and all references herein to the corresponding "Basket Stock Issuer" shall thereupon be deemed to mean the issuer(s) of the security(ies) comprising such Distribution Property, in each case as and to the extent determined by the Calculation Agent.

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 Calculation Date for which the Performance Rate of such Basket Stock will be determined.

Notwithstanding anything to the contrary in Section 4.1, if, as a result of Reorganization, the Calculation Agent determines in its sole discretion that a commercially reasonable result cannot be achieved by valuing Distribution Property as provided in Section 4.1 with respect to a Basket Stock that becomes subject to a Reorganization Event, then the Calculation Agent, will, in its sole discretion, substitute another U.S. common stock listed on a national securities exchange or quotation system for such Basket Stock. In such case, the original Basket Stock will be deleted from the Basket and will not be considered for purposes of determining the Basket Return Payment hereunder. The Initial Price of the substituted Basket Stock shall be determined by the Calculation Agent in its sole discretion. The Calculation Agent shall have the right, in its sole discretion, to make such adjustments as are necessary to the calculation of the Performance Rate of the substituted Basket Stock as to preserve the respective economic interests herein of the Company and the Holders immediately prior to such Reorganization Event.

SECTION 5.1 Additional Payments and Right of Redemption upon the Occurrence of a Tax Event.

The Company will pay to any Holder who is a resident of the United States (for the purposes of The Canada-United States Tax Convention (1980)) such additional amounts (the "Additional Tax Amount") as may be necessary in order that every net payment of the principal of and interest on the Securities of this series and any other amounts payable on such Securities, after withholding for or on account of any present or future tax, assessment or governmental charge imposed upon such payment by Canada, will not be less than the amount provided for in such Securities to be then due and

payable. The Company will not, however, be required to make any payment of Additional Tax Amounts to any beneficial owner for or on account of:

The Company shall have the right to redeem the Securities of this series prior to maturity as provided in the Indenture but subject to the provisions hereinafter set forth, in whole but not in part, if at any time prior to maturity if it is or will be obligated to pay the Additional Tax Amounts as described in this Section 5.1.

Notice of such redemption shall not be given earlier than sixty days prior to the earliest date on which the Company would obligated to pay such Additional Tax Amounts if a payment in respect of the Securities of this series were then due. Notice of redemption will be given not less than thirty and not more than sixty days prior to the date fixed for redemption, which date and applicable redemption price will be specified in the notice. Prior to giving any notice of redemption, the Company will deliver to the Trustee (i) a certificate stating that it is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the Company's right to so redeem have occurred and (ii) an opinion of independent counsel or written advise of a qualified tax expert, such counsel or expert being reasonably acceptable to the Trustee, to such effect based on such statement of facts.

The redemption price of the Securities will be determined by the Calculation Agent in a manner reasonably calculated to preserve the Holder's and the Company's relative economic position.

Except as provided in Section 5.1, the Securities of this series are not redeemable (at the option of the Company or the Holder) before maturity.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

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 at least a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and 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.

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 and any other amounts required to be paid on this Security at the times, places and rate, and in the coin or currency, herein prescribed.

The Securities are issuable in registered form, without coupons, in denominations of $1,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture, and subject to certain limitations therein set forth and to the limitations described below, if applicable, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

As provided in the Indenture and subject to certain limitations set forth therein and as may be set forth on the face hereof, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Issuer in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

This Security is exchangeable only if (x) the Depository notifies the Company that it is unwilling or unable to continue as Depository for this Security or if at any time the Depository ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, (y) the Company in its sole discretion determines that this Security shall be exchangeable for certificated Securities in registered form or (z) an Event of Default, or an event which with the passage of time or the giving of notice would become an Event of Default, with respect to the Securities represented hereby has occurred and is continuing, provided that the definitive Securities so issued in exchange for this permanent Security shall be in denominations of $1,000 and any integral multiple of $1,000 in excess thereof and be of like aggregate principal amount and tenor as the portion of this permanent Security to be exchanged, and provided further that, unless the Company agrees otherwise, Securities of this series in certificated registered form will be issued in exchange for this permanent Security, or any portion hereof, only if such Securities in certificated registered form were requested by written notice to the Trustee or the Securities Registrar by or on behalf of a person who is beneficial owner of an interest hereof given through the Holder hereof. Except as provided above, owners of beneficial interests in this permanent Security will not be entitled to receive physical delivery of Securities in certificated registered form and will not be considered the Holders thereof for any purpose under the Indenture.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

Absent manifest error, all determinations made by the Calculation Agent shall be final and binding on the Holder. 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 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 any 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.

No recourse for the payment of the principal or interest (and Additional Amounts, if any) on this Security, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or in any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation of either of them, either directly or through the Company or any successor corporation of either of them, whether by virtue of any constitution, statute or rule or law or by the enforcement of any assessment or penalty or otherwise, all such liability being by the acceptance hereof and as a condition of and as part of the consideration for the issue hereof, expressly waived and released.

The provisions set forth in Sections 10.01(b) and (c) of the Indenture shall not apply to the Securities of this series.

The Indenture and the Securities shall be governed by and construed in accordance with the laws of the State of New York.

Notices to Holders of Registered Securities shall be sufficiently given if in writing and mailed, first-class postage prepaid, to each Holder entitled thereto, at his last address as it appears in the Security Register.
