[REVERSE OF NOTE]

CREDIT SUISSE (USA), INC.
Reverse Convertible Securities Linked to the Value of a Basket of Equities
due October 31, 2007

This Note is one of a duly authorized issue of debentures, notes, bonds or other evidences of indebtedness of the Company (the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to a senior indenture, dated as of June 1, 2001 (the “Indenture”), between the Company and the Bank of New York (the “Trustee”), as successor Trustee to JPMorgan Chase Bank, to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, and the Holders of the Securities.  The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as provided in the Indenture.  This Note is one of a series designated as the Reverse Convertible Securities Linked to the Value of a Basket of Equities due October 31, 2007 (the “Note”).

A coupon will be payable on this Note of 14.25% per annum on the principal amount from October 31, 2006.  The coupon payment will be payable quarterly in arrears on January 31, 2007, April 30, 2007, July 31, 2007 and October 31, 2007.

This Note is payable in the manner, with the effect and subject to the conditions provided in the Indenture.

If a payment date is not a business day as defined in the Indenture at a place of payment, payment may be made at that place on the next succeeding day that is a business day, and no interest shall accrue for the intervening period.

The Indenture provides that, without prior notice to any Holders, the Company and the Trustee may amend the Indenture and the Securities of any series with the written consent of the Holders of a majority in principal amount of the outstanding Securities of all series affected by such amendment (all such series voting as one class), and the Holders of a majority in principal amount of the outstanding Securities of all series affected thereby (all such series voting as one class) may waive future compliance by the Company with any provision of the Indenture or the Securities of such series by written notice to the Trustee; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment or waiver, including a waiver of past defaults, may not: (i) extend the stated maturity of the Principal of, or any sinking fund obligation or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the rate of interest thereon (including any amount in respect of original issue discount), or any premium payable with respect thereto, or adversely affect the rights of such Holder under any mandatory redemption or repurchase provision or any right of redemption or repurchase at the option of such Holder, or reduce the amount of the Principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the maturity thereof or the amount thereof provable in bankruptcy, or

R-1

change any place of payment where, or the currency in which, any Security of such series or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the due date therefor; (ii) reduce the percentage in principal amount of outstanding Securities of the relevant series the consent of whose Holders is required for any such supplemental indenture, for any waiver of compliance with certain provisions of the Indenture or certain Defaults and their consequences provided for in the Indenture; (iii) waive a Default in the payment of Principal of or interest on any Security of such Holder; or (iv) modify any of the provisions of the Indenture governing supplemental indentures with the consent of Securityholders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each outstanding Security affected thereby.

The Indenture provides that, subject to certain conditions, the Holders of at least a majority in principal amount (or, if any Securities are Original Issue Discount Securities, such portion of the Principal as is then accelerable) of the outstanding Securities of all series affected (voting as a single class), by notice to the Trustee, may waive an existing Default or Event of Default with respect to the Securities of such series and its consequences, except a Default in the payment of Principal of or interest on any Security or in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of the Holder of each outstanding Security affected.  Upon any such waiver, such Default shall cease to exist, and any Event of Default with respect to the Securities of such series arising therefrom shall be deemed to have been cured, for every purpose of the Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto.

The Indenture provides that a series of Securities may include one or more tranches (each a “tranche”) of Securities, including Securities issued in a Periodic Offering.  The Securities of different tranches may have one or more different terms, including authentication dates and public offering prices, but all the Securities within each such tranche shall have identical terms, including authentication date and public offering price.  Notwithstanding any other provision of the Indenture, subject to certain exceptions, with respect to sections of the Indenture concerning the execution, authentication and terms of the Securities, redemption of the Securities, Events of Default of the Securities, defeasance of the Securities and amendment of the Indenture, if any series of Securities includes more than one tranche, all provisions of such sections applicable to any series of Securities shall be deemed equally applicable to each tranche of any series of Securities in the same manner as though originally designated a series unless otherwise provided with respect to such series or tranche pursuant to a board resolution or a supplemental indenture establishing such series or tranche.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the Redemption Amount of this Note in the manner, at the place, at the time and in the coin or currency herein prescribed.

The Securities are issuable initially only in registered form without coupons in denominations of $10,000 and any integral multiples of $5,000 in excess of that amount at the office or agency of the Company in the Borough of Manhattan, The City of New York, and in the manner and subject to the limitations provided in the Indenture.

R-2

The Securities will not be redeemable at the option of the Company prior to maturity.

The Company will not be required to pay any Additional Amounts on the Securities.

Maturity Date

The Maturity Date of the Securities is October 31, 2007 (the “Maturity Date”); however, if a market disruption event exists in respect of a basket component on the Valuation Date, as determined by the Calculation Agent, the Maturity Date will be the later of October 31, 2007, and the third business day following the date on which the closing price for the basket component is calculated.

Redemption Amount

The Company will redeem the Securities at maturity for a redemption amount (the “redemption amount”) that will be based on the performance of an equally weighted basket of seven reference shares (the “basket components”), on any day from but not including October 26, 2006, which is the initial setting date, to and including October 25, 2007 (the “Valuation Date” and such period, the “relevant period”). The redemption amount at maturity will equal the sum of the delivery amounts for each basket component, and may consist of cash, shares or a combination of cash and shares. The delivery amount for each basket component is calculated as follows:

(1)                                  If the closing price of the basket component on its relevant exchange is not less than its knock-in level, which is 70% of the Initial Share Price for such basket component, on any day during the relevant period, the delivery amount for that basket component will be the cash delivery amount.  The cash delivery amount is a cash payment equal to the principal amount of the Securities multiplied by the weighting of that basket component.

(2)                                  If (i) the closing price of the basket component on its relevant exchange is less than its knock-in level on any day during the relevant period and (ii) the closing price of the basket component on its relevant exchange on the valuation date (the “Final Share Price”) is greater than or equal to the Initial Share Price, the delivery amount for that basket component will be the cash delivery amount.

(3)                                Otherwise, the delivery amount for that basket component will be the physical delivery amount.  The physical delivery amount is the number of shares of such basket component equal to the principal amount of the Securities divided by the Initial Share Price for such basket component, and multiplied by the weighting of that basket component.  The market value of the physical delivery amount will be less than the principal amount of the Securities and may be zero.

R-3

A “business day” means a day, other than a Saturday, Sunday or a day on which banking institutions in New York, New York are generally authorized or obligated by law, regulation or executive order to close and that is also a Trading Day.

A “trading day” means any day, as determined by the Calculation Agent, on which trading is generally conducted for a basket component (or, but for the occurrence of a market disruption event, would have been generally conducted) on the relevant exchange and for options and other derivative instruments on the basket component on the Chicago Mercantile Exchange and the Chicago Board Options Exchange, which we refer to collectively as the related exchanges, other than a day on which the relevant exchange or the related exchanges are scheduled to close prior to their regular weekday closing time.

Market Disruption Events

For each basket component, or, in the case of a basket component that is ADRs, for both the basket component and the underlying ordinary shares represented by such basket component, if no Final Share Price is available on the Valuation Date because of a market disruption event, as determined by the Calculation Agent in its sole discretion, the Calculation Agent may postpone the calculation of the Final Share Price until the earlier of the date such market disruption event has ceased or three trading days after the Valuation Date, as the case may be.  On such third trading day, in the event there still exists a market disruption event, the Calculation Agent will determine the Final Share Price using its good faith estimate of the value for such basket component as of the closing time on the relevant exchange on such date.  If a market disruption event exists on the Valuation Date, the Maturity Date of the Securities will be the later of the original maturity date and the third business day following the day on which the Final Share Price is calculated. No interest will accrue or other payment be payable because of any postponement of the Maturity Date.  The Valuation Date for each basket component not affected by a market disruption event will be the scheduled valuation date.

A “market disruption event” means the occurrence or existence of any suspension of or limitation imposed on trading (by reason of movements in price exceeding limits permitted by any relevant exchange or market or otherwise) of, or the unavailability, through a recognized system of public dissemination of transaction information, of accurate price, volume or related

R-4

information in respect of (a) a basket component, (b) any options or futures contracts, or any options on such futures contracts, relating to the shares of a basket component, or (c) in the case of a basket component that is ADRs, the underlying ordinary shares represented by such ADRs or any options or futures contracts, or any options on such futures contracts, relating to such underlying ordinary shares, if, in each case, in the determination of the Calculation Agent, in its sole discretion, any such suspension, limitation or unavailability is material.

For purposes of determining whether a market disruption event has occurred for a basket component: (1) a limitation on the hours or number of days of trading will not constitute a market disruption event if it results from an announced change in the regular business hours of the relevant exchange; (2) a decision permanently to discontinue trading in the relevant options or futures contract will not constitute a market disruption event; (3) limitations pursuant to New York Stock Exchange Rule 80A—Index Arbitrage Trading Restrictions (or any applicable rule or regulation enacted or promulgated by the New York Stock Exchange, any other self-regulatory organization or the SEC of similar scope as determined by the Calculation Agent) on trading during significant market fluctuations will constitute a market disruption event; (4) a suspension of trading in an options contract on the shares of a basket component by the primary securities market trading in such options, if available, by reason of (x) a price change exceeding limits set by such securities exchange or market, (y) an imbalance of orders relating to such contracts or (z) a disparity in bid and ask quotes relating to such contracts will constitute a suspension or material limitation of trading in options contracts related to the shares of a basket component notwithstanding that such suspension or material limitation is less than two hours; (5) a suspension, absence or material limitation of trading on the primary securities market on which options contracts related to the shares of a basket component is traded will not include any time when such securities market is itself closed for trading under ordinary circumstances; and (6) a “suspension or material limitation” on an exchange or in a market will include a suspension or material limitation of trading by one class of investors provided that such suspension continues for more than two hours of trading or during the last one-half hour period preceding the close of trading on the relevant exchange or market (but will not include limitations imposed on certain types of trading under New York Stock Exchange Rule 80A or any applicable rule or regulation enacted or promulgated by the New York Stock Exchange, NASDAQ, any other self-regulatory organization or the SEC of a similar scope or as a replacement for Rule 80A, as determined by the Calculation Agent) and will not include any time when such exchange or market is closed for trading as part of such exchange’s or market’s regularly scheduled business hours.

Antidilution Adjustments

General

For each basket component, the Calculation Agent will adjust the Initial Share Price and the physical delivery amount if certain corporate actions and other events described below (each of which, an “adjustment event”), occur, and the Calculation Agent determines that such adjustment event has a diluting or concentrative effect on the theoretical value of the basket component.  Set forth below are examples of how adjustment events may lead to adjustments to the Initial Share Price and the physical delivery amount.

R-5

For purposes of the antidilution adjustments described herein, for any basket component that is an ADR, the Calculation Agent will make the specified antidilution adjustments if an adjustment event occurs with respect to the ordinary shares underlying the reference shares (as if those underlying shares were the reference shares for purposes of the antidilution adjustments) and also if the number of ordinary shares represented by one reference share changes from its current ratio of one ordinary share to one reference share.

For each basket component, upon the occurrence of an adjustment event that the Calculation Agent determines has a diluting or concentrative effect on the theoretical value of the basket component, for purposes only of determining whether (i) the closing price of the basket component is less than the knock-in level and (ii) the Final Share Price is less than the Initial Share Price, the Calculation Agent will typically adjust the Initial Share Price according to the following formula:

and may, when appropriate, also adjust the knock in level.

The physical delivery amount will be adjusted by the Calculation Agent as set forth in the specific examples below.

The adjustments described below do not cover all events that could affect the value of the Securities.

Adjustments

For each basket component, if an adjustment event occurs and the Calculation Agent determines that the event has a diluting or concentrative effect on the theoretical value of such basket component, the Calculation Agent will calculate a corresponding adjustment to the Initial Share Price and the physical delivery amount as the Calculation Agent determines appropriate to account for that diluting or concentrative effect. The Calculation Agent will also determine the effective date of that adjustment, and the replacement of such basket compponent, if applicable, in the event of consolidation or merger. Upon making any such adjustment, the Calculation Agent will give notice as soon as practicable to the Trustee, stating the adjustment of the Initial Share Price and physical delivery amount.

If more than one adjustment event occurs, the Calculation Agent will make an adjustment for each such adjustment event in the order in which they occur, and on a cumulative basis.  Accordingly, having adjusted the Initial Share Price and the physical delivery amount for the first such adjustment event, the Calculation Agent will adjust the Initial Share Price and the physical delivery amount for the second adjustment event, applying the required adjustment to the Initial Share Price and the physical delivery amount as already adjusted for the first adjustment event, and so on for each subsequent adjustment event.

The Calculation Agent will not have to adjust the Initial Share Price and the physical delivery amount for any adjustment event unless the adjustment would result in a change to the

R-6

Initial Share Price or the physical delivery amount of at least 0.1% in the Initial Share Price or the physical delivery amount that would apply without the adjustment.  The Initial Share Price and the physical delivery amount resulting from any adjustment would be rounded up or down, as appropriate, to, in the case of the Initial Share Price, the nearest cent, and, in the case of the physical delivery amount, the nearest thousandth, with one-half cent and five ten-thousandths, respectively, being rounded upwards.

If an adjustment event requiring antidilution adjustment occurs, the Calculation Agent will make any adjustments with a view to offsetting, to the extent practical, any change in the Holders’ economic position relative to the Securities that results solely from that event.  The Calculation Agent may, in its sole discretion, modify any antidilution adjustments as necessary to ensure an equitable result.

The Calculation Agent has sole discretion in making all determinations with respect to antidilution adjustments, including any determination as to whether an adjustment event requiring an antidilution adjustment has occurred, as to the nature of the adjustment required and how it will be made.  In the absence of manifest error, those determinations will be conclusive for all purposes and will be binding on the Holders and the Company, without any liability on the part of the Calculation Agent.  Upon written request, the Calculation Agent will provide information about any adjustments it makes.

Events requiring an antidilution adjustment

The following is a list of adjustment events that may require an antidilution adjustment:

(a)                                  a subdivision, consolidation or reclassification of the shares of one or more basket components or a free distribution or dividend of the shares of one or more basket components to existing holders of reference shares by way of bonus, capitalization or similar issue;

(b)                                 a dividend or other distribution to existing holders of the shares of one or more basket components of (i) shares of the basket component, (ii) other share capital or securities granting the right to payment of dividends equally or proportionately with such payments to holders of the shares of such basket component or (iii) any other type of securities, rights or warrants in any case for payment (in cash or otherwise) at less than the prevailing market price as determined by the Calculation Agent;

(c)                                  the declaration by one or more of the issuers of the basket components of an extraordinary or special dividend or other distribution whether in cash or shares of such basket component or other assets;

(d)                                 a repurchase of its common stock by one or more of the issuers of the basket components whether out of profits or capital and whether the consideration for such repurchase is cash, securities or otherwise;

(e)                                  a consolidation of the issuers of one or more of the basket components with another company or merger of one or more of the issuers of the basket components with another company;

R-7

(f)                                    a change by the issuer of a basket component that is an ADR of the ratio of underlying ordinary shares represented by one ADR; and

(g)                                 any other similar event that may have a diluting or concentrative effect on the theoretical value of one or more of the basket components.

Certain adjustment events are discussed in greater detail below.

Stock splits

A stock split is an increase in the number of a corporation’s outstanding shares of stock without any change in its stockholders’ equity.

If the reference shares are subject to a stock split, the Calculation Agent will adjust the physical delivery amount to equal the sum of the prior physical delivery amount—i.e., the physical delivery amount before that adjustment—and the product of (i) the number of additional shares issued in the stock split with respect to each of the shares of such basket component multiplied by (ii) the prior physical delivery amount.

Reverse stock splits

A reverse stock split is a decrease in the number of a corporation’s outstanding shares of stock without any change in its stockholders’ equity.

For each basket component, if the shares of such basket component are subject to a reverse stock split, the Calculation Agent will adjust the physical delivery amount to equal the product of the prior physical delivery amount and the quotient of (i) the number of shares of such basket component outstanding immediately after the reverse stock split becomes effective divided by (ii) the number of shares of such basket component outstanding immediately before the reverse stock split becomes effective.

Stock dividends

In a stock dividend, a corporation issues additional shares of its stock to all holders of its outstanding stock in proportion to the shares they own.

For each basket component, if the shares of such basket component are subject to a stock dividend payable in the reference shares, then the Calculation Agent will adjust the physical delivery amount to equal the sum of the prior physical delivery amount and the product of (i) the number of additional shares issued in the stock dividend with respect to each of the shares of such basket component multiplied by (ii) the prior physical delivery amount.

Other dividends and distributions

If one or more of the issuers of the basket components declares a dividend to be distributed to holders of record of the shares of such basket component as of a date falling in the period that begins on the day immediately following the Valuation Date and ends on the day immediately prior to the Maturity Date, any such dividend will not be paid to Holders.

R-8

The physical delivery amount will not be adjusted to reflect any dividends or distributions paid with respect to shares of such basket component, other than (i) stock dividends described above; (ii) issuances of transferable rights and warrants as described in “—Transferable rights and warrants” below; and (iii) extraordinary dividends as described below.

A dividend or other distribution with respect to the shares of one or more of the basket components will be deemed to be an “extraordinary dividend” if its per share value exceeds that of the immediately preceding non-extraordinary dividend, if any, for the shares of such basket component by an amount equal to at least 10% of the market price of the shares of such basket component on the business day before the ex-dividend date for the extraordinary dividend.  The ex-dividend date for any dividend or other distribution is the first day on which the shares of such basket component trade without the right to receive that dividend or distribution.  For each basket component, if an extraordinary dividend occurs, the Calculation Agent will adjust the physical delivery amount to equal the product of (1) the prior physical delivery amount times (2) a fraction, the numerator of which is the market price of the shares of such basket component on the business day before the ex-dividend date and the denominator of which is the amount by which that market price exceeds the extraordinary dividend adjustment amount.  For each basket component, the “extraordinary dividend adjustment amount” with respect to an extraordinary dividend for the shares of such basket component equals:  (i) for an extraordinary dividend that is paid in lieu of a regular quarterly dividend, the amount of the extraordinary dividend per share of the shares of such basket component minus the amount per share of the immediately preceding dividend, if any, that was not an extraordinary dividend for the shares of such basket component, or (ii) for an extraordinary dividend that is not paid in lieu of a regular quarterly dividend, the amount per share of the extraordinary dividend.

For each basket component, 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.  For each basket component, a distribution on the shares of the basket component that is a dividend payable in shares of the basket component, an issuance of rights or warrants or a spin-off event and that is also an extraordinary dividend will result in an adjustment to the physical delivery amount only as described in “—Stock dividends” above, “—Transferable rights and warrants” below or “—Reorganization events” below, as the case may be, and not as described here.

Transferable rights and warrants

For each basket component, if the issuer of such basket component issues transferable rights or warrants to all holders of shares of such basket component to subscribe for or purchase shares of such basket component at an exercise price per share that is less than the market price of the shares of such basket component on the business day before the ex-dividend date for the issuance, then the physical delivery amount will be adjusted by multiplying the prior physical delivery amount by the following fraction: (i) the numerator will be the sum of the number of shares of such basket component outstanding at the close of business on the day before that ex-dividend date and the total number of additional shares of such basket component offered for subscription or purchase under those transferable rights or warrants, and (ii) the denominator will be the sum of the number of shares of such basket component outstanding at the close of business on the day before that ex-dividend date and the product of (1) the total number of additional shares of such basket component offered for subscription or purchase under the

R-9

transferable rights or warrants times (2) the exercise price of those transferable rights or warrants divided by the market price on the business day before that ex-dividend date.

Reorganization events

For each basket component, any of the following shall constitute a reorganization event: (i) the shares of such basket component are reclassified or changed, including, without limitation, as a result of the issuance of any tracking stock by the issuer of such basket component, (ii) the issuer of the basket component has been subject to any merger, combination or consolidation and is not the surviving entity, (iii) the issuer of the basket component completes a statutory exchange of securities with another corporation, (iv) the issuer of the basket component is liquidated, (v) the issuer of the basket component issues to all of its shareholders equity securities of an issuer other than the issuer of the basket component (other than in a transaction above) (a “spinoff stock”) or (vi) the shares of the basket component are the subject of a tender or exchange offer or going private transaction on all of the outstanding shares.

Adjustments for reorganization events

For each basket component, if any reorganization event occurs, in each case as a result of which the holders of the basket component receive any equity security listed on a national securities exchange or traded on The Nasdaq National Market (a “marketable security”), other securities or other property, assets or cash (collectively “exchange property”), for purposes of determining the physical delivery amount following the effective date for such reorganization event (or, if applicable, in the case of spinoff stock, the ex-dividend date for the distribution of such spinoff stock), the physical delivery amount will be based on the following:

(a) if shares of the basket component continue to be outstanding, the prior physical delivery amount (if applicable, as reclassified upon the issuance of any tracking stock) on the relevant date (taking into account any adjustments for any distributions described under clause (c)(i) below);

(b) for each marketable security received in such reorganization event (each a “new stock”), including the issuance of any tracking stock or spinoff stock or the receipt of any stock received in exchange for shares of the basket component, the amount of new stock received with respect to one share of the basket component, as adjusted to the relevant date (taking into account any adjustments for distributions described under clause (c)(i) below); and

(c) for any cash and any other property or securities other than marketable securities received in such reorganization event (the “non-stock exchange property”), (i) if the combined value of the amount of non-stock exchange property received per share of the basket component, as determined by the Calculation Agent in its sole discretion on the effective date of such reorganization event (the “non-stock exchange property value”), by holders of the basket component is less than 25% of the closing price of the shares of the basket component on the trading day immediately prior to the effective date of such reorganization event, an amount of the shares of the basket component, if applicable, and of any new stock received in connection with such reorganization event, if applicable, in proportion to the relative closing prices of the shares of the basket component and any such new stock, and with an aggregate value equal to the non-stock exchange property value, based on such closing prices, in each case as determined by the

R-10

Calculation Agent in its sole discretion on the effective date of such reorganization event, or (ii) if the non-stock exchange property value is equal to or exceeds 25% of the closing price of the shares of the basket component on the trading day immediately prior to the effective date relating to such reorganization event or, if the shares of the basket component are surrendered exclusively for non-stock exchange property (in each case, an “alternate stock event”), a number of shares of the alternate stock (as defined below) with a value on the effective date of such reorganization event equal to the non-stock exchange property value.  The “alternate stock” will be the common stock of the company with a price volatility on the measurement date (each as defined below) that is nearest (whether higher or lower) to the price volatility of the shares of the basket component, as selected by the Calculation Agent from a group of five stocks then included in the S&P 500 Index (or, if publication of such index is discontinued, any successor or substitute index selected by the Calculation Agent in its sole discretion).  The stocks from which the alternate stock is selected will be the five stocks with the largest market capitalization among the stocks then included in the S&P 500 Index (or such successor index) with the same primary “Industry” Standard IndustrialClassification Code (“SIC Code”) as the issuer of the basket component; provided that if there are fewer than five stocks with the same primary “Industry” SIC Code as the issuer of the basket component, the Calculation Agent will identify additional stocks then included in the S&P 500 Index (or such successor index), from the following categories, selecting stocks, as required, in each succeeding category in descending order of market capitalization, beginning with the stock in each category with the largest capitalization: first, stocks with the same primary “Industry Group” classification as the issuer of the basket component; second, stocks with the same primary “Major Group” classification as the issuer of the basket component; and third, stocks with the same primary “Division” classification as the issuer of the basket component; provided, further, that none of the five stocks from which the alternate stock will be selected will be a stock that is subject to a trading restriction under the trading restriction policies of Credit Suisse or any of its affiliates that would materially limit the ability of Credit Suisse or any of its affiliates to hedge the Securities with respect to such stock (a “hedging restriction”).  “Industry,” “Industry Group,” “Major Group” and “Division” have the meanings assigned by the Office of Management and Budget, or any successor federal agency responsible for assigning SIC codes.  If the SIC Code system of classification is altered or abandoned, the Calculation Agent may select an alternate classification system and implement similar procedures. “Price volatility” means the average historical price volatility for the period of 100 trading days ending on the trading day immediately prior to the first public announcement of the relevant reorganization event (the “measurement date”) as such average historical price volatility for such stock is displayed on Bloomberg screen Equity HVG (using the settings N = 100 and Market: T) (or any successor thereto); provided that if the price volatility of the shares of the basket component or any stock identified in this sub-paragraph is not then displayed on Bloomberg, then the Calculation Agent, in its sole discretion, will determine the applicable price volatility.

In the case of a consummated tender or exchange offer or going-private transaction involving consideration of particular types, exchange property shall be deemed to include the amount of cash or other property delivered by the offeror in the tender or exchange offer (in an amount determined on the basis of the rate of exchange in such tender or exchange offer or going-private transaction).  In the event of a tender or exchange offer or a going-private transaction with respect to exchange property in which an offeree may elect to receive cash or

R-11

other property, exchange property shall be deemed to include the kind and amount of cash and other property received by offerees who elect to receive cash.

For each basket component, if a reorganization event occurs, the property distributed in the event will be substituted for the common stock of the issuer of the relevant basket component as described above.  Consequently, references to the common stock of the issuer of the basket component mean any property that is distributed in a reorganization event and comprises the adjusted physical delivery amount.  Similarly, references to the issuer of the reference shares mean any successor entity in a reorganization event.

In the event that the Calculation Agent determines that an adjustment should be made to the physical delivery amount for a basket component as a result of one or more events or circumstances not otherwise described above (even if such event or circumstance is specifically excluded from the operation of the provisions described above), the Calculation Agent shall determine as soon as practicable what adjustment (if any) is fair and reasonable to take account thereof.

Events of Default and Acceleration

In case an Event of Default (as defined in the Indenture) with respect to the Securities shall have occurred and be continuing, the amount declared due and payable upon any acceleration of the Securities (in accordance with the acceleration provisions set forth in the prospectus) will be determined by the Calculation Agent and will equal, for each security, the arithmetic average, as determined by the Calculation Agent, of the fair market value of the Securities as determined by at least three but not more than five broker-dealers (which may include Credit Suisse Securities (USA) LLC or any of the Company’s other subsidiaries or affiliates) as will make such fair market value determinations available to the Calculation Agent.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered Holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon) for the purpose of receiving payment of, or on account of, the redemption amount hereof, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Note, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

The Calculation Agent for the Securities (the “Calculation Agent”) is Credit Suisse International.  The calculations and determinations of the Calculation Agent will be final and binding upon all parties (except in the case of manifest error).  The Calculation Agent will
