[REVERSE OF NOTE]


 


CREDIT SUISSE (USA), INC.

Reverse Convertible Securities Linked to the Diamond Offshore Drilling, Inc.


due March 30, 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
JPMorgan Chase Bank, as trustee (the “Trustee”), 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 Performance of Diamond Offshore Drilling, Inc.,
due March 30, 2007 (the “Note”).


 


A coupon will be payable on this Note of
9.75% per annum on the principal amount from March 31, 2006. The coupon
payment will be payable quarterly in arrears on June 30, 2006, September 29,
2006, December 29, 2006, and March 30, 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 $5,000 and any
integral multiples of $1,000 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 March 30, 2007 (the “Maturity
Date”); however, if a market disruption event exists on the Valuation Date, as
determined by the Calculation Agent, the Maturity Date will be the later of March 30,
2007, and the third business day following the date on which the closing price
for the reference shares is calculated.


 


Redemption
Amount


 


The Company will redeem
the Securities at maturity for a redemption amount in cash that will be based
on the performance of the reference shares during the term of the Securities
(the “redemption amount”):


 


(1)          If the closing price of
the reference shares on the New York Stock Exchange (the “relevant exchange”)
is not less than the knock-in level, which is 70% of the Initial Share Price,
on any day from but not including March 28, 2006, which is the initial
setting date, to and including March 26, 2007 (the “Valuation Date”), the
redemption amount will equal a cash payment equal to 100% of the principal
amount of the Securities.


 


(2)          If (i) the closing
price of the reference shares on the relevant exchange is less than the
knock-in level on any day from but not including March 28, 2006, which is
the initial setting date, to and including the Valuation Date and (ii) the
closing price of the reference shares on the relevant exchange on the Valuation
Date, which we refer to as the final share price, is greater than or equal to
the Initial Share Price, the redemption amount will equal a cash payment equal
to 100% of the principal amount of the Securities.


 


(3)          Otherwise, the
redemption amount will be the physical delivery amount. The physical delivery
amount will be the number of reference shares per $1,000 principal amount of
Securities equal to $1,000 divided by the Initial Share Price. The market value
of the physical delivery amount will be less than the principal amount of the
Securities and may be zero.


 


The “Initial Share Price”
is $87.73.


 


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 reference shares (or, but for the occurrence of a market
disruption event, would have been generally conducted) on the relevant exchange
and for options


 


R-3

















 


and other derivative instruments on the reference
shares 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


 


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 the reference
shares 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.


 


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 information in respect of (a) the reference shares or (b) any
options or futures contracts, or any options on such futures contracts,
relating to the reference 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:  (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 reference shares 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 reference shares
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 reference
shares are 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


 


R-4

















 


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.


 


Based on the information currently available to us, on
October 27, 1997, the New York Stock Exchange suspended all trading during
the one-half hour period preceding the close of trading pursuant to New York
Stock Exchange Rule 80B and, on each of September 11, 12, 13 and 14,
2001, the New York Stock Exchange suspended all trading for the entire day due
to certain terrorist activity. If any such suspension of trading occurred
during the term of the Securities, it would constitute a market disruption
event. The existence or non-existence of these circumstances, however, is not
necessarily indicative of the likelihood of these circumstances arising or not
arising in the future.


 


Antidilution
Adjustments


 


General


 


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 reference
shares. Set forth below are examples of how adjustment events may lead to
adjustments to the Initial Share Price and the physical delivery amount.


 


Upon the occurrence of an
adjustment event that the Calculation Agent determines has a diluting or
concentrative effect on the theoretical value of the reference shares, for
purposes only of determining whether (i) the price of the reference shares
is less than or equal to the knock-in level and (ii) the final share price
is less than or equal to the Initial Share Price, the Calculation Agent will
typically adjust the Initial Share Price according to the following formula:


 


	
  adjusted initial share price = initial share price

  	
  X

  	
  prior physical delivery amount

  	
   

  
	
  adjusted physical delivery amount

  	
   

  



 


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.


 


R-5

















 


Adjustments


 


If an adjustment event occurs and the Calculation Agent
determines that the event has a diluting or concentrative effect on the
theoretical value of the reference shares, 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 the reference shares,
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 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.


 


R-6

















 


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 reference shares or a free distribution or dividend
of any reference shares to existing holders of reference shares by way of
bonus, capitalization or similar issue;


 


(b)                                 a dividend or other
distribution to existing holders of reference shares of (i) the reference
shares, (ii) other share capital or securities granting the right to
payment of dividends equally or proportionately with such payments to holders
of the reference shares 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 the
issuer of the reference shares of an extraordinary or special dividend or other
distribution whether in cash or reference shares or other assets;


 


(d)                                 a repurchase of its common
stock by the issuer of the reference shares whether out of profits or capital
and whether the consideration for such repurchase is cash, securities or
otherwise;


 


(e)                                  a consolidation of the
issuer of the reference shares with another company or merger of the issuer of
the reference shares with another company; and


 


(f)                                    any other similar event that
may have a diluting or concentrative effect on the theoretical value of
the reference shares.


 


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. As a result of a stock split, each outstanding share will
be worth less.


 


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 reference shares times (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. As a result of a reverse stock split, each outstanding
share will be worth more.


 


If the reference shares 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 reference shares outstanding immediately after the reverse


 


R-7

















 


stock split becomes effective divided by (ii) the
number of reference shares 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. As a result of a stock dividend, each outstanding share will
be worth less.


 


If the reference shares 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 reference shares times (ii) the prior
physical delivery amount.


 


Other dividends and distributions


 


If the issuer of the reference shares declares a dividend
to be distributed to holders of record of the reference shares 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.


 


The physical delivery amount will not be adjusted to
reflect any dividends or distributions paid with respect to the reference
shares, 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
reference shares 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 reference shares by an amount equal to at least
10.00% of the market price of the reference shares on the business day before
the extraordinary dividend date. The ex dividend date for any dividend or other
distribution is the first day on which the reference shares trade without the
right to receive that dividend or distribution. 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 reference shares 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. The “extraordinary dividend adjustment amount” with respect
to an extraordinary dividend for the reference shares 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 reference shares minus the amount per
share of the immediately preceding dividend, if any, that was not an
extraordinary dividend for the reference shares, 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.


 


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 the reference shares that is a dividend payable in the
reference shares, an issuance of rights or warrants or a spin-off


 


R-8

















 


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


 


If the issuer of the reference shares issues transferable
rights or warrants to all holders of the reference shares to subscribe for or
purchase the reference shares at an exercise price per share that is less than
the market price of the reference shares on the business day before the
extraordinary 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 reference shares outstanding at the
close of business on the day before that ex dividend date and the total number
of additional reference shares offered for subscription or purchase under those
transferable rights or warrants, and (ii) the denominator will be the sum
of the number of reference shares outstanding at the close of business on the
day before that ex dividend date and the product of (1) the total number
of additional reference shares offered for subscription or purchase under the
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 extraordinary dividend date.


 


Reorganization events


 


Each of the following may be a reorganization
event:  (i) the reference shares are
reclassified or changed; (ii) the issuer of the reference shares has been
subject to a merger, consolidation or other combination and either is not the
surviving entity or is the surviving entity but all outstanding reference
shares are exchanged for or converted into other property; (iii) a
statutory share exchange involving outstanding reference shares and the
securities of another entity occurs, other than as part of an event
described above; (iv) the issuer of the reference shares effects a
spin-off (i.e., issues to all holders of reference shares common stock equity
securities of another issuer) other than as part of an event described
above; (v) the issuer of the reference shares sells or otherwise transfers
its property and assets as an entirety or substantially as an entirety to
another entity (each of the events in clauses (i) through (v) above,
a “merger event”); (vi) a takeover offer, tender offer, exchange offer,
solicitation, proposal or other event by any entity or person that results in
such entity or person purchasing, or otherwise obtaining or having the right to
obtain, by conversion or other means, not less than a majority of the
outstanding voting reference shares as determined by the Calculation Agent,
based upon the making of filings with governmental or self-regulatory agencies
or such other information as the Calculation Agent deems relevant, which we
refer to as a tender offer; (vii) the exchange on which the reference
shares trade announces that pursuant to the rules of such exchange, the
reference shares cease (or will cease) to be listed, traded or publicly quoted
on it for any reason (other than a merger event or tender offer) and are not
immediately re-listed, re-traded or re-quoted on another major U.S. exchange or
quotation system (a “delisting event”); and (viii) the issuer of the
reference shares is liquidated, dissolved or wound up or is subject to a
proceeding under any applicable bankruptcy, insolvency or other similar law
(each, an “insolvency event”).

Adjustments for reorganization events


 


If a merger event occurs and a holder of the reference
shares that makes no election, vote or decision in connection with such merger
event would receive as full or partial consideration ordinary or common shares
of any person (other than the issuer of the reference shares) that are publicly
quoted, traded or listed on any major U.S. exchange or quotation system (the “new
shares”), then the Calculation
Agent will adjust the physical delivery amount so as to consist of the amount
and type of property distributed in the reorganization event in respect of the
prior physical delivery amount. In this instance, if more than one type of
property is distributed, the physical delivery amount will be adjusted so as to
consist of each type of property distributed, in a proportionate amount, so
that the value of each type of property comprising the new physical delivery
amount as a percentage of the total value of the new physical delivery amount
equals the value of that type of property as a percentage of the total value of
all of the property distributed in the reorganization event.


 


If a tender offer occurs, and the holder of the reference
shares can elect to receive new shares as full or partial consideration in
respect of such tender offer, then the Calculation Agent will adjust the
physical delivery amount in accordance with the preceding paragraph.


 


If a merger event occurs, and the consideration in respect
of such event does not consist in full or in part of new shares (or in the
case of a tender offer, a holder of the reference shares would not be able to
elect to receive in full or in part any new shares as consideration in
respect of such tender offer), then the Calculation Agent will accelerate the
Maturity Date to the day which is four business days after the approval date
(as defined below). The amount payable at maturity will be determined as
described below under “Events of default and acceleration.”  The approval date is the closing date of a
merger event or, in the case of a tender offer, the date on which the person or
entity making the tender offer acquires or acquires the right to obtain the
relevant percentage of reference shares.


 


If a delisting event or an insolvency event occurs, the
Calculation Agent will accelerate the Maturity Date to the day which is four
business days after the announcement date (as defined below). On the Maturity
Date, the Company will pay to each Holder the physical delivery amount and for
the purposes of such calculation, the final share price will be deemed to be
the closing price of the reference shares on the business day immediately prior
to the announcement date. The announcement date means, in the case of a
delisting event, the day of the first public announcement by the relevant
exchange that the reference shares will cease to trade or be publicly quoted on
such exchange, or, in the case of an insolvency event, the day of the first
public announcement of the institution of a proceeding or presentation of a
petition or passing of a resolution (or other analogous procedure in any
jurisdiction) that leads to an insolvency event with respect to the issuer of
the reference shares.


 


If a merger event or tender offer occurs, coupon payment
amounts will accrue on the Securities through the approval date and be paid on
the accelerated Maturity Date. Such coupon payments will be calculated using a
360-day year comprised of twelve 30-day months. If a delisting event or an
insolvency event occurs, the Company will pay all remaining scheduled unpaid
coupon payments due to a Holder through the scheduled Maturity Date on the
accelerated Maturity Date.


 


R-10

















 


For the purposes of making an adjustment required by a
reorganization event, the Calculation Agent will determine the value of each
type of property distributed in the distribution, in its sole discretion. For
any property distributed consisting of new shares, the Calculation Agent will
use the closing price of the new shares on the approval date. The Calculation
Agent may value other types of property in any manner it determines, in
its sole discretion, to be appropriate. If a holder of the common stock of the
issuer of the reference shares elects to receive different types or
combinations of types of property in the reorganization event, such property
will consist of the types and amounts of each type distributed to a holder that
makes no election, as determined by the Calculation Agent.


 


If a reorganization event occurs and the Calculation Agent
adjusts the physical delivery amount to consist of the property distributed in
the reorganization event as described above, the Calculation Agent will make
further antidilution adjustments for later events that affect such property, or
any component of such property, comprising the new physical delivery amount. The
Calculation Agent will do so to the same extent that it would make adjustments
if the common stock of the issuer of the reference shares was outstanding and
was affected by the same kinds of events. If a subsequent reorganization event
affects only a particular component of the physical delivery amount, the
required adjustment will be made with respect to that component, as if it alone
were the physical delivery amount. For example, if the issuer of the reference
shares merges into another company and each share of its common stock is
converted into the right to receive two new shares of the surviving company and
a specified amount of cash, the physical delivery amount will be adjusted to
consist of two new shares and the specified amount of cash per reference share.
The Calculation Agent will adjust the common share component of the new
physical delivery amount to reflect any later stock split or other event,
including any later reorganization event, that affects the new shares, to the
extent described in this section entitled “Antidilution adjustments” as if
the new shares were the common stock of the issuer of the reference shares. In
that event, the cash component will not be adjusted but will continue to be a
component of the physical delivery amount. Consequently, Holders who receive
reference shares at maturity will be entitled to receive, for each $1,000 of
the outstanding principal amount of the Securities being exchanged, all
components of the physical delivery amount in effect on the exchange date, with
each component having been adjusted on a sequential and cumulative basis for
all relevant events requiring adjustment on or before the exchange date.


 


If a reorganization event occurs,
the property distributed in the event will be substituted for the common stock
of the issuer of the reference shares as described above. Consequently,
references to the common stock of the issuer of the reference shares 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.


 


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


 


R-11

















 


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.

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.

agreement contained in the Indenture or any indenture supplemental thereto or

law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise, all such
