instruments of substantially similar tenor signed by such Holders in person or
by an agent or proxy duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee and, where it is hereby expressly
required, to the Company. The Trustee shall promptly deliver to the Company
copies of all such instruments and records delivered to the Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders of
Securities signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent or proxy, or of the
holding by any Person of a Security, shall be sufficient for any purpose of this
Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and
the Company if made in the manner provided in this Section.

     (2)    The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.

     (3)    The principal amount and serial number of any Security held by any
Person, and the date of his holding the same, shall be proved by the Security
Register.

     (4)    The fact and date of execution of any such instrument or writing and
the authority of the Person executing the same may also be proved in any other
manner which the Trustee deems sufficient; and the Trustee may in any instance
require further proof with respect to any of the matters referred to in this
Section.

     (5)    The Company may set any day as the record date for the purpose of
determining the Holders entitled to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action, or to vote on
any action, authorized or permitted by this Indenture to be given or taken by
Holders. Promptly and in any case not later than ten days after setting a record
date, the Company shall notify the Trustee and the Holders of such record date.
If not set by the Company prior to the first solicitation of a Holder made by
any Person in respect of any such action, or, in the case of any such vote,
prior to such vote, the record date for any such action or vote shall be the
30th day (or, if later, the date of the most recent list of Holders required to
be provided pursuant to Section 9.1) prior to such first solicitation or vote,
as the case may be. With regard to any record date, the Holders on such date (or
their duly appointed agents or proxies), and only such Persons,

                                      -11-

not such Holders remain Holders after such record date. Notwithstanding the
foregoing, the Company shall not set a record date for, and the provisions of
this paragraph shall not apply with respect to, any notice, declaration or
direction referred to in the next paragraph.

     Upon receipt by the Trustee from any Holder of (i) any notice of default or
breach referred to in Section 5.1(5), if such default or breach has occurred and
is continuing and the Trustee shall not have given such a notice to the Company,
(ii) any declaration of acceleration referred to in Section 5.1(5), if an Event
of Default has occurred and is continuing and the Trustee shall not have given
such a declaration to the Company, or (iii) any direction referred to in
Section 5.12, if the Trustee shall not have taken the action specified in such
direction, then, with respect to clauses (ii) and (iii), a record date shall
automatically and without any action by the Company or the Trustee be set for
determining the Holders entitled to join in such declaration or direction, which
record date shall be the close of business on the tenth day (or, if such day is
not a Business Day, the first Business Day thereafter) following the day on
which the Trustee receives such declaration or direction, and, with respect to
clause (i), the Trustee may set any day as a record date for the purpose of
determining the Holders entitled to join in such notice of default. Promptly
after such receipt by the Trustee of any such declaration or direction referred
to in clause (ii) or (iii), and promptly after setting any record date with
respect to clause (i), and as soon as practicable thereafter, the Trustee shall
notify the Company and the Holders of any such record date so fixed. The Holders
on such record date (or their duly appointed agents or proxies), and only such
Persons, shall be entitled to join in such notice, declaration or direction,
whether or not such Holders remain Holders after such record date; PROVIDED
that, unless such notice, declaration or direction shall have become effective
by virtue of Holders of the requisite principal amount of Securities on such
record date (or their duly appointed agents or proxies) having joined therein on
or prior to the 90th day after such record date, such notice, declaration or
direction shall automatically and without any action by any Person be canceled
and of no further effect. Nothing in this paragraph shall be construed to
prevent a Holder (or a duly appointed agent or proxy thereof) from giving,
before or after the expiration of such 90-day period, a notice, declaration or
direction contrary to or different from, or, after the expiration of such
period, identical to, the notice, declaration or direction to which such record
date relates, in which event a new record date in respect thereof shall be set
pursuant to this paragraph. In addition, nothing in this paragraph shall be
construed to render ineffective any notice, declaration or direction of the type
referred to in this paragraph given at any time to the Trustee and the Company
by Holders (or their duly appointed agents or proxies) of the requisite
principal amount of Securities on the date such notice, declaration or direction
is so given.

     (6)    Except as provided in Section 5.12 and Section 5.13, any request,
demand, authorization, direction, notice, consent, election, waiver or other Act
of the Holder of any Security shall bind every future Holder of the same
Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

sufficiently given to Holders if in writing and mailed, first-class postage
prepaid or delivered by an overnight delivery service, to each Holder of a
Security affected by such event, at the address of such Holder as it appears in
the Security Register, not earlier than the earliest date and not later than the
latest date prescribed for the giving of such notice.

     Neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Security shall affect the sufficiency of
such notice with respect to other Holders of Securities. In case by reason of
the suspension of regular mail service or by reason of any other cause it shall
be impracticable to give such notice by mail, then such notification to Holders
of Securities as shall be made with the approval of the Trustee, which approval
shall not be unreasonably withheld, shall constitute a sufficient notification
to such Holders for every purpose hereunder.

     Such notice shall be deemed to have been given when such notice is mailed.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

made on the Interest Payment Date, Redemption Date, Repurchase Date or Change in
Control Repurchase Date, or at the Stated Maturity or by such last day for
conversion; PROVIDED, HOWEVER, that in the case that payment is made on such
succeeding Business Day, no interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date,
Repurchase Date, Change in Control Repurchase Date, Stated Maturity or last day
for conversion, as the case may be.

executing such Securities, as evidenced by their execution thereof.

     Upon their original issuance, Securities issued as contemplated by the
Purchase Agreement to Qualified Institutional Buyers in reliance on Rule 144A

           Authorized Signatory

                                [FORM OF REVERSE]

     This Security is one of a duly authorized issue of securities of the
Company designated as its "1.00% Convertible Senior Notes due August 1, 2010"
(herein called the "Securities"), limited in aggregate principal amount to U.S.
$100,000,000 (or $125,000,000 if the Initial Purchasers' Option is exercised in
full), issued and to be issued under an Indenture, dated as of August 1, 2003
(herein called the "Indenture"), between the Company and American Stock Transfer
& Trust Company, as Trustee (herein called the "Trustee", which term includes
any successor trustee 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. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities are exchangeable for a like aggregate principal amount of Securities
of any authorized denominations as requested by the Holder surrendering the same
upon surrender of the Security or Securities to be exchanged, at the Corporate
Trust Office of the Trustee. The Trustee upon such surrender by the Holder will
issue the new Securities in the requested denominations.

     No sinking fund is provided for the Securities.

     The Securities are also subject to redemption at the option of the Company
at any time on or after August 1, 2008, in whole or in part, upon not less than
30 nor more than 60 days' notice to the Holders prior to the Redemption Date at
a Redemption Price equal to 100% of the principal amount, together, in each
case, with accrued and unpaid interest and Liquidated Damages, if any, to, but
excluding, the Redemption Date; PROVIDED, HOWEVER, that interest installments on
Securities whose Stated Maturity is on or prior to such Redemption Date will be
payable to the Holders of such Securities, or one or more Predecessor
Securities, of record at the close of business on the relevant Record Dates
referred to on the face hereof, all as provided in the Indenture.

     In the event of a redemption of the Securities, the Company will not be
required (a) to register the transfer or exchange of Securities for a period of
15 days immediately preceding the date notice is given identifying the serial
numbers of the Securities called for such redemption or (b) to register the
transfer or exchange of any Security, or portion thereof, called for redemption.

     Notice to the Holders will be given not more than 60 and not less than 30
days prior to the Redemption Date as provided in the Indenture.

     In any case where the due date for the payment of the principal of or
interest or Liquidated Damages on any Security or the last day on which a Holder
of a Security has a right to convert his Security shall be, at any Place of
Payment or Place of Conversion as the case may be, a day on which banking
institutions at such Place of Payment or Place of Conversion are authorized or
obligated by law or executive order to close, then payment of principal,
interest, or Liquidated Damages, or delivery for conversion of such Security
need not be made on or by such date at such place but may be made on or by the
next succeeding day at such place which is not a day on which banking
institutions are authorized or obligated by law or executive order to close,
with the same force and effect as if made on the date for such payment or the
date fixed for redemption or

                                      -22-
<Page>

repurchase, or by such last day for conversion, and no interest shall accrue on
the amount so payable for the period after such date.

     Subject to and upon compliance with the provisions of the Indenture, the
Holder of this Security is entitled, at his option, to convert any Security that
is an integral multiple of $1,000 into fully paid and nonassessable shares
(calculated as to each conversion to the nearest 1/100th of a share) of Common
Stock of the Company at the Conversion Rate, determined as hereinafter provided,
in effect at the time of conversion and subject to the adjustments described
below, as follows:

     (1)    if, on or prior to August 1, 2008, the Closing Price Per Share of
the Common Stock for at least 20 Trading Days in the period of the 30
consecutive Trading Days ending on the first day of a Conversion Period was more
than 110% of the then current Conversion Price of the Securities, then the
Holder thereof will be entitled to convert such Security during that Conversion
Period;

     (2)    if, on any date after August 1, 2008 and prior to the Stated
Maturity, the Closing Price Per Share of the Common Stock is more than 110% of
the then current Conversion Price of the Securities, then the Holder thereof
will be entitled to convert such Security at all times thereafter;

     (3)    if the Company distributes to all or substantially all holders of
Common Stock rights, options or warrants entitling them to purchase Common Stock
at less than the Closing Price Per Share of the Common Stock on the last Trading
Day preceding the declaration of such distribution, then the Holder will be
entitled to convert such Security during the period specified below;

     (4)    if the Company distributes to all or substantially all holders of
Common Stock cash, assets, debt securities or capital stock, which distribution
has a per share value as determined by the Board of Directors exceeding 5% of
the Closing Price Per Share of the Common Stock on the last Trading Day
preceding the declaration of such distribution, then the Holder will be entitled
to convert such Security during the period specified below; or

     (5)    if the Company becomes a party to a consolidation, merger or sale of
all or substantially all of the Company's assets where such consolidation,
merger or sale of all or substantially all of the Company's assets constitutes a
Change in Control, then the Holder will be entitled to convert such Security
during the period specified below.

     In the case of a distribution contemplated by clauses (3) and (4) above,
the Company will notify Holders at least 20 days prior to the ex-dividend date
for such distribution (the "Distribution Notice"). Once the Company has given
the Distribution Notice, Holders may surrender their Securities for conversion
at any time until the earlier of the close of business on last Business Day
preceding the ex-dividend date or the Company's announcement that such
distribution will not take place. Notwithstanding the foregoing, in the event of
a distribution contemplated by clauses (3) and (4) above, Holders may not
convert the Securities if the Holders may participate in such distribution
without converting their Securities. In the event of a consolidation, merger or
sale of all or substantially all of the Company's assets as contemplated by
clause (5) above, the Company will notify Holders at least 20 days prior to the
anticipated closing date of such transaction (the "Merger Notice"). Once the
Company has given the Merger Notice, the Holders may, in the event of such

                                      -23-
<Page>

consolidation, merger or sale of all or substantially all of the Company's
assets, surrender Securities for conversion at any time from and after the date
which is 15 days prior to the anticipated closing date of such transaction until
the date which is 15 days after the actual closing date of such transaction.

     Subject to the provisions of the Indenture, the Holder of a Security is
entitled, at its option, to convert the principal amount of this Security (or
any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess
thereof) into Common Stock for the five Business Day period after any five
consecutive Trading Day period in which the average Trading Prices for the
Securities for such five Trading Day period was less than 95% of the average
Conversion Value for the Securities during such period; PROVIDED, HOWEVER, if on
the Conversion Date, the Closing Price Per Share of Common Stock is greater than
the then current Conversion Price of the Securities and less than or equal to
110% of the then current Conversion Price of the Securities, a Holder surrenders
its Securities for conversion and the Securities are not otherwise convertible,
then such Holder will receive, at the Company's option, cash, Common Stock or a
combination of cash and Common Stock with a value equal to the principal amount
of such Holder's Securities on such Conversion Date. The Trustee will determine
the average Trading Prices after being requested by the Company to do so as more
fully described in the Indenture. If the Company elects to pay the Holder in
Common Stock or in a combination of cash and Common Stock, the Company will
notify the Holder in writing, and the Common Stock will be valued at 100% of the
average Closing Price Per Share for the five Trading Days immediately following
the Conversion Date.

     Subject to and upon compliance with the terms described above and the
provisions of the Indenture, the Holder of this Security is entitled, at his
option, at any time on or before the close of business on the date of Maturity,
or in case this Security or a portion hereof is called for redemption or the
Holder hereof has exercised his right to require the Company to repurchase this
Security or such portion hereof, then in respect of this Security until the
Business Day immediately preceding, but (unless the Company defaults in making
the payment due upon redemption or repurchase, as the case may be) not after,
the close of business on the Business Day immediately preceding the Redemption
Date, the Repurchase Date or the Change in Control Repurchase Date, as the case
may be, to convert this Security (or any portion of the principal amount hereof
that is an integral multiple of U.S.$1,000, PROVIDED that the unconverted
portion of such principal amount is U.S.$1,000 or any integral multiple of
U.S.$1,000 in excess thereof) into fully paid and nonassessable shares of Common
Stock of the Company at an initial Conversion Rate of 25.0000 shares of Common
Stock for each U.S.$1,000 principal amount of Securities (or at the current
adjusted Conversion Rate if an adjustment has been made as provided in the
Indenture) by surrender of this Security, duly endorsed or assigned to the
Company or in blank and, in case such surrender shall be made during the period
from the close of business on any Regular Record Date next preceding any
Interest Payment Date to the opening of business on such Interest Payment Date
(except if this Security or portion thereof has been called for redemption on a
Redemption Date or is repurchasable on a Repurchase Date or Change in Control
Repurchase Date occurring, in either case, during such period and, as a result,
the right to convert this Security would otherwise terminate in such period if
not exercised), also accompanied by payment in New York Clearing House or other
funds acceptable to the Company of an amount equal to the interest payable on
such Interest Payment Date on the principal amount of this Security then being
converted, and also the conversion notice hereon duly executed, to the

                                      -24-
<Page>

Company at the Corporate Trust Office of the Trustee, or at such other office or
agency of the Company, subject to any laws or regulations applicable thereto and
subject to the right of the Company to terminate the appointment of any
Conversion Agent (as defined below) as may be designated by it for such purpose
in the Borough of Manhattan, The City of New York, or at such other offices or
agencies as the Company may designate (each a "Conversion Agent"), PROVIDED,
FURTHER, that if this Security or portion hereof has been called for redemption
on a Redemption Date or is repurchasable on a Repurchase Date or Change in
Control Repurchase Date occurring, in either case, during the period from the
close of business on any Regular Record Date next preceding any Interest Payment
Date to the opening of business on such succeeding Interest Payment Date, and as
a result, the right to convert this Security would otherwise terminate in such
period if not exercised and this Security is surrendered for conversion during
such period, then the Holder of this Security on such Regular Record Date will
be entitled to receive the interest accruing hereon from the Interest Payment
Date next preceding the date of such conversion to such succeeding Interest
Payment Date and the Holder of this Security who converts this Security or a
portion hereof during such period shall not be required to pay such interest
upon surrender of this Security for conversion. Subject to the provisions of the
preceding sentence and, in the case of a conversion after the close of business
on the Regular Record Date next preceding any Interest Payment Date and on or
before the close of business on such Interest Payment Date, to the right of the
Holder of this Security (or any Predecessor Security of record as of such
Regular Record Date) to receive the related installment of interest to the
extent and under the circumstances provided in the Indenture, no cash payment or
adjustment is to be made on conversion for interest accrued hereon from the
Interest Payment Date next preceding the day of conversion, or for dividends on
the Common Stock issued on conversion hereof. The Company shall thereafter
deliver to the Holder the fixed number of shares of Common Stock (together with
any cash adjustment, as provided in the Indenture) into which this Security is
convertible and such delivery will be deemed to satisfy the Company's obligation
to pay the principal amount of this Security. No fractions of shares or scrip
representing fractions of shares will be issued on conversion, but instead of
any fractional interest (calculated to the nearest 1/100th of a share) the
Company shall pay a cash adjustment as provided in the Indenture. The Conversion
Rate is subject to adjustment as provided in the Indenture. In addition, the
Indenture provides that in case of certain consolidations or mergers to which
the Company is a party (other than a consolidation or merger that does not
result in any reclassification, conversion, exchange or cancellation of the
Common Stock) or the conveyance, transfer, sale or lease of all or substantially
all of the property and assets of the Company, the Indenture shall be amended,
without the consent of any Holders of Securities, so that this Security, if then
Outstanding, will be convertible thereafter, during the period this Security
shall be convertible as specified above, only into the kind and amount of
securities, cash and other property receivable upon such consolidation, merger,
conveyance, transfer, sale or lease by a holder of the number of shares of
Common Stock of the Company into which this Security could have been converted
immediately prior to such consolidation, merger, conveyance, transfer, sale or
lease (assuming such holder of Common Stock is not a Constituent Person or an
Affiliate of a Constituent Person, failed to exercise any rights of election and
received per share the kind and amount received per share by a plurality of
Non-electing Shares). No adjustment in the Conversion Rate will be made until
such adjustment would require an increase or decrease of at least one percent of
such rate, PROVIDED that any adjustment that would otherwise be made will be
carried forward and taken into account in the computation of any subsequent
adjustment. A Holder may convert all or part of this Security by delivering this
Security at the corporate trust office of the

                                      -25-
<Page>

Trustee accompanied by a duly signed and completed conversion notice, a copy of
which may be obtained by the Trustee. [IF THIS SECURITY IS A GLOBAL SECURITY,
THEN INSERT - DTC will affect the conversion upon notice from the Holder of a
beneficial interest in this Security in accordance with DTC's rules and
procedures.] The conversion date will be the date on which the Security and the
duly signed and completed conversion notice are so delivered.

     If this Security is a Registrable Security (as defined in this Indenture),
then the Holder of this Security [IF THIS SECURITY IS A GLOBAL SECURITY, THEN
INSERT -- (including any Person that has a beneficial interest in this
Security)] and the Common Stock of the Company issuable upon conversion hereof
is entitled to the benefits of a Registration Rights Agreement, dated as of
August 1, 2003, executed by the Company (the "Registration Rights Agreement")
between the Company and the Initial Purchasers. Pursuant to the Registration
Rights Agreement, the Company has agreed for the benefit of the Holders from
time to time of the Registrable Securities that it will, at its expense, (a)
within 90 days after the Issue Date file a shelf registration statement (the
"Shelf Registration Statement") with the Commission with respect to resales of
the Registrable Securities, (b) use its best efforts to cause such Shelf
Registration Statement to be declared effective by the Commission within 180
days after the Issue Date of the Securities, PROVIDED, HOWEVER, that the Company
may, upon written notice to all the Holders, postpone having the Shelf
Registration Statement declared effective for a reasonable period not to exceed
90 days if the Company possesses material non-public information, the disclosure
of which would have a material adverse effect on the Company and its
subsidiaries taken as a whole, and (c) use its best efforts to maintain such
Shelf Registration Statement effective under the Securities Act until the
earliest of (i) the sale of all outstanding Registrable Securities registered
under such Shelf Registration; (ii) the expiration of the period referred to in
Rule 144(k) of the Securities Act with respect to Registrable Securities held by
non-affiliates of the Company, (iii) all the Registrable Securities have ceased
to be outstanding (whether as a result of redemption, repurchase, cancellation,
conversion or otherwise); and (iv) two years after the effective date of such
Shelf Registration Statement (the "Effectiveness Period"). The Company will be
permitted to suspend the use of the prospectus which is part of the Shelf
Registration Statement during certain periods of time as provided in the
Registration Rights Agreement.

     If (i) on or prior to 90 days following the Issue Date, a Shelf
Registration Statement has not been filed with the Commission, or (ii) on or
prior to the 180th day following the Issue Date, such Shelf Registration
Statement is not declared effective (each, a "Registration Default"), additional
interest ("Liquidated Damages") will accrue on this Restricted Security from and
including the day following such Registration Default to but excluding the day
on which such Registration Default has been cured. Liquidated Damages will be
paid semi-annually in arrears, with the first semi-annual payment due on the
first Interest Payment Date, as applicable, in respect of the Restricted
Securities following the date on which such Liquidated Damages begin to accrue,
and will accrue at a rate per annum equal to one-quarter of one percent (0.25%)
of the principal amount of the Restricted Securities to and including the 90th
day following such Registration Default and at a rate per annum equal to
one-half of one percent (0.50%) thereof from and after the 91st day following
such Registration Default. Pursuant to the Registration Rights Agreement, in the
event that the Shelf Registration Statement ceases to be effective (or the
Holders of Registrable Securities are otherwise prevented or restricted by the
Company from effecting sales pursuant thereto) (an "Effective

                                      -26-
<Page>

Failure") during the Effectiveness Period for more than 30 days, whether or not
consecutive, during any 90-day period or for more than 90 days, whether or not
consecutive, during any 12-month period, then the interest rate borne by the
Restricted Securities shall increase by an additional one-half of one percent
(0.50%) per annum from the 31st day of the applicable 90-day period or the 91st
day of the applicable 12-month period until the earlier of (A) such time as the
Effective Failure is cured or (B) the Effectiveness Period expires.

     Whenever in this Security there is a reference, in any context, to the
payment of the principal of, or interest on, or in respect of, any Security,
such mention shall be deemed to include mention of the payment of Liquidated
Damages payable as described in the preceding paragraph to the extent that, in
such context, Liquidated Damages are, were or would be payable in respect of
such Security and express mention of the payment of Liquidated Damages (if
applicable) in any provisions of this Security shall not be construed as
excluding Liquidated Damages in those provisions of this Security where such
express mention is not made.

     If this Security is a Registrable Security and the Holder of this Security
[IF THIS SECURITY IS A GLOBAL SECURITY, THEN INSERT -- (including any Person
that has a beneficial interest in this Security)] elects to sell this Security
pursuant to the Shelf Registration Statement then, by its acceptance hereof,
such Holder of this Security agrees to be bound by the terms of the Registration
Rights Agreement relating to the Registrable Securities which are the subject of
such election.

            Subject to the terms and conditions of the Indenture, the Company
shall repurchase all or a portion of the Securities (any such portion begin at
least $1,000 or an integral multiple of $1,000 in excess thereof and provided
that no single Security may be repurchased in part unless the portion of the
principal amount of such Security to be Outstanding after such repurchase is
equal to $1,000 or integral multiples of $1,000 in excess thereof) at the option
of the Holder on August 1, 2008 (the "Repurchase Date"), at a repurchase price
equal to 100% of the principal amount of the Securities to be repurchased, plus
interest accrued but unpaid to, but excluding, such Repurchase Date (the
"Repurchase Price"). At the option of the Company, the Repurchase Price may be
paid in cash, or subject to the fulfillment by the Company of the conditions set
forth in the Indenture, by delivery of shares of Common Stock having a fair
market value to the Repurchase Price (less any cash payments), or a combination
of cash and Common Stock.

     If a Change in Control occurs, the Holder of this Security, at the Holder's
option, shall have the right, in accordance with the provisions of the
Indenture, to require the Company to repurchase this Security (or any portion of
the principal amount hereof that is at least $1,000 or an integral multiple of
$1,000 in excess thereof, PROVIDED that the portion of the principal amount of
this Security to be Outstanding after such repurchase is at least equal to
U.S.$1,000) at a Change in Control Repurchase Price equal to 100% of the
principal amount thereof plus interest accrued to the Change in Control
Repurchase Date. At the option of the Company, the Change in Control Repurchase
Price may be paid in cash or, subject to the conditions provided in the
Indenture, by delivery of shares of Common Stock having a fair market value
equal to the Change in Control Repurchase Price.

                                      -27-
<Page>

     For purposes of the two preceding paragraphs, the fair market value of
shares of Common Stock shall be determined by the Company and shall be equal to
95% of the average of the Closing Prices Per Share for the five consecutive
Trading Days immediately preceding and including the third Trading Day prior to
the Repurchase Date or the Change in Control Repurchase Price, as the case may
be. Whenever in this Security there is a reference, in any context, to the
principal of any Security as of any time, such reference shall be deemed to
include reference to the Repurchase Price or the Change in Control Repurchase
Price, as the case may be, payable in respect of such Security to the extent
that such Repurchase Price or Change in Control Repurchase Price, as the case
may be, is, was or would be so payable at such time, and express mention of the
Repurchase Price or the Change in Control Repurchase Price, as the case may be,
in any provision of this Security shall not be construed as excluding the
Repurchase Price or the Change in Control Repurchase Price, as the case may be
so payable in those provisions of this Security when such express mention is not
made.

     [THE FOLLOWING PARAGRAPH SHALL APPEAR IN EACH GLOBAL SECURITY:

     In the event of a deposit or withdrawal of an interest in this Security,
including an exchange, transfer, redemption, repurchase or conversion of this
Security in part only, the Trustee, as custodian of the Depositary, shall make
an adjustment on its records to reflect such deposit or withdrawal in accordance
with the Applicable Procedures.]

     [THE FOLLOWING PARAGRAPH SHALL APPEAR IN EACH SECURITY THAT IS NOT A GLOBAL
SECURITY:

     In the event of redemption, repurchase or conversion of this Security in
part only, a new Security or Securities for the unredeemed, unrepurchased or
unconverted portion hereof will be issued in the name of the Holder hereof.]

     If an Event of Default shall occur and be continuing, the principal of all
the Securities, together with accrued and unpaid interest and Liquidated
Damages, if any, to the date of declaration, may be declared due and payable in
the manner and with the effect provided in the Indenture. Upon payment (i) of
the amount of principal so declared due and payable, together with accrued
interest to the date of declaration, and (ii) of interest on any overdue
principal and, to the extent permitted by applicable law, overdue interest, all
of the Company's obligations in respect of the payment of the principal of and
interest on the Securities shall terminate.

     [THE FOLLOWING PARAGRAPH SHALL APPEAR IN EACH GLOBAL SECURITY:

     In the event of a withdrawal of an interest in this Security resulting from
any redemption, repurchase or conversion of this Security in part only, the
Trustee, as custodian of the Depositary, shall make an adjustment on its records
to reflect such withdrawal in accordance with the Applicable Procedures.]

     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 under the Indenture at
any time by the Company and the Trustee with the written consent of the Holders
of not less than a majority in principal amount of the Securities at the time
Outstanding. The Indenture also contains provisions permitting the Holders of a
majority in principal

                                      -28-
<Page>

amount of the Securities at the time Outstanding, on behalf of the Holders of
all the Securities, 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 in exchange therefore or in lieu hereof
whether or not notation of such consent or waiver is made upon this Security or
such other Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default, the Holders of not less
than 25% in principal amount of the Outstanding Securities shall have made
written request to the Trustee to institute proceedings in respect of such Event
of Default as Trustee and offered the Trustee reasonable indemnity and the
Trustee shall not have received from the Holders of a majority in principal
amount of the Securities Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not
apply to any suit instituted by the Holder of this Security for the enforcement
of any payment of principal hereof or interest (including Liquidated Damages)
hereon on or after the respective due dates expressed herein or for the
enforcement of the right to convert this Security as provided in the Indenture.

     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 interest (including
Liquidated Damages) on this Security at the times, places and rate, and in the
coin or currency, herein prescribed or to convert this Security as provided in
the Indenture.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable on the Security Register
upon surrender of this Security for registration of transfer at the Corporate
Trust Office of the Trustee or at such other office or agency of the Company as
may be designated by it for such purpose in the Borough of Manhattan, The City
of New York (which shall initially be an office or agency of the Trustee), or at
such other offices or agencies as the Company may designate, 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 thereof or his
attorney duly authorized in writing, and thereupon one or more new Securities,
of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees by the Security Registrar. 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 recover any tax or
other governmental charge payable in connection therewith.

     Interest on the Securities shall be computed on the basis of a 360-day year
of twelve 30-day months.

     Prior to due presentation of a 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 such Security is

                                      -29-

registered, as the owner thereof for all purposes, whether or not such Security
be overdue, and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary.

     No recourse for the payment of the principal or interest on this Security
and no recourse under or upon any obligation, covenant or agreement of the
Company in the Indenture or any indenture supplemental thereto or in any
Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, employee, agent, officer or
director or subsidiary, as such, past, present or future, of the Company or of
any successor corporation, either directly or through the Company or any
successor corporation, whether by virtue of any constitution, statute or rule of
law or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of consideration for the
issue hereof, expressly waived and released.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, UNITED STATES OF AMERICA.

                                 THE SECURITIES

Section 3.1    TITLE AND TERMS.

     The aggregate principal amount of Securities which may be authenticated and
delivered under this Indenture is limited to U.S. $100,000,000, as such amount
may be increased, but not by an amount in excess of $25,000,000, solely as a
result of the purchase of additional Securities (the "Additional Securities")
pursuant to the option granted by the Company in the Purchase Agreement to the
several Initial Purchasers (the "Initial Purchasers' Option"), except for
Securities authenticated and delivered pursuant to Section 3.4, Section 3.5,
Section 3.6, Section 8.5, Section 12.2 or Section 14.4(6) in exchange for, or in
lieu of, other Securities previously authenticated and delivered under this
Indenture.

     (1)    The Securities shall be known and designated as the "1.00%
Convertible Senior Notes due August 1, 2010" of the Company. Their Stated
Maturity shall be August 1, 2010 and they shall bear interest on their principal
amount from August 1, 2003, payable semi-annually in arrears on February 1 and
August 1 in each year, commencing February 1, 2004, at the rate of 1.00% per
annum until the principal thereof is due and at the rate of 1.00% per annum on
any overdue principal and, to the extent permitted by law, on any overdue
interest; PROVIDED, HOWEVER, that payments shall only be made on a Business Day
as provided in Section 1.12.

     Upon receipt by the Trustee of an Officers' Certificate stating that the
Initial Purchasers have elected to purchase from the Company a specified
aggregate principal amount of Additional Securities not to exceed a total of
$25,000,000 (all such elections in accordance with this paragraph pursuant to
the Purchase Agreement), the Trustee shall authenticate and make available for
delivery such specified aggregate principal amount of such Additional Securities
to or upon a Company Request, and such specified aggregate principal amount of
such Additional Securities shall be considered part of the original aggregate
principal amount of the Securities.

     The principal of and interest on the Securities shall be payable as
provided in the form of Securities set forth in Section 2.2, and the Repurchase
Price or the Change in Control Repurchase Prices, as the case may be, whether
payable in cash or in shares of Common Stock or a combination thereof, shall be
payable at such places as are identified in the Company Notice given pursuant to
Section 14.4 (any city in which any Paying Agent is located being herein called
a "Place of Payment").

     The Registrable Securities are entitled to the benefits of a Registration
Rights Agreement as provided by Section 10.8 and in the form of Security set
forth in Section 2.2. The Securities are entitled to the payment of Liquidated
Damages as provided by Section 10.8.

     The Securities shall be redeemable at the option of the Company at any time
on or after August 1, 2008, in whole or in part, subject to the conditions and
as otherwise provided in Article XI and in the form of Security set forth in
Section 2.2.

                                      -35-
<Page>

     The Securities shall be convertible as provided in Article XII (any city in
which any Conversion Agent is located being herein called a "Place of
Conversion").

     The Securities shall be subject to repurchase by the Company at the option
of the Holders as provided in Article XIV.

Section 3.2    DENOMINATIONS.

     The Securities shall be issuable only in registered form, without coupons,
in denominations of U.S.$1,000 and integral multiples of U.S.$1,000 in excess
thereof.

Section 3.3    EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its Chief Executive Officer, its President, its Chief Financial
Officer, one of its Executive Vice Presidents, and attested by its Chief
Operating Officer, Controller or Secretary. Any such signature may be manual or
facsimile.

     Securities bearing the manual or facsimile signature of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities executed by the Company to the
Trustee or to its order for authentication, together with a Company Order for
the authentication and delivery of such Securities, and the Trustee in
accordance with such Company Order shall authenticate and make available for
delivery such Securities as in this Indenture provided.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature of an authorized signatory, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

Section 3.4    GLOBAL SECURITIES; NON-GLOBAL SECURITIES; BOOK-ENTRY PROVISIONS.

     (1)    Global Securities

            (A)    Each Global Security authenticated under this Indenture shall
be registered in the name of the Depositary designated by the Company for such
Global Security or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Security shall
constitute a single Security for all purposes of this Indenture. The Company
hereby appoints DTC as the Depositary.

                                      -36-
<Page>

            (B)    Except for exchanges of Global Securities for definitive,
Non-global Securities at the sole discretion of the Company, no Global Security
may be exchanged in whole or in part for Securities registered, and no transfer
of a Global Security in whole or in part may be registered, in the name of any
Person other than the Depositary for such Global Security or a nominee thereof
unless (A) such Depositary (i) has notified the Company that it is unwilling or
unable to continue as Depositary for such Global Security or (ii) has ceased to
be a clearing agency registered as such under the Exchange Act or announces an
intention permanently to cease business or does in fact do so or (B) there shall
have occurred and be continuing an Event of Default with respect to such Global
Security. In such event, if a successor Depositary for such Global Security is
not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such ineligibility, the Company will execute, and the
Trustee, upon receipt of an Officers' Certificate directing the authentication
and delivery of Securities, will authenticate and deliver, Securities, in any
authorized denominations in an aggregate principal amount equal to the principal
amount of such Global Security in exchange for such Global Security.

            (C)    If any Global Security is to be exchanged for other
Securities or canceled in whole, it shall be surrendered by or on behalf of the
Depositary or its nominee to the Trustee, as Security Registrar, for exchange or
cancellation, as provided in this Article III. If any Global Security is to be
exchanged for other Securities or canceled in part, or if another Security is to
be exchanged in whole or in part for a beneficial interest in any Global
Security, in each case, as provided in Section 3.5, then either (A) such Global
Security shall be so surrendered for exchange or cancellation, as provided in
this Article III, or (B) the principal amount thereof shall be reduced or
increased by an amount equal to the portion thereof to be so exchanged or
canceled, or equal to the principal amount of such other Security to be so
exchanged for a beneficial interest therein, as the case may be, by means of an
appropriate adjustment made on the records of the Trustee, as Security
Registrar, whereupon the Trustee, in accordance with the Applicable Procedures,
shall instruct the Depositary or its authorized representative to make a
corresponding adjustment to its records. Upon any such surrender or adjustment
of a Global Security, the Trustee shall, subject to Section 3.5(3) and as
otherwise provided in this Article III, authenticate and deliver any Securities
issuable in exchange for such Global Security (or any portion thereof) to or
upon the order of, and registered in such names as may be directed by, the
Depositary or its authorized representative. Upon the request of the Trustee in
connection with the occurrence of any of the events specified in the preceding
paragraph, the Company shall promptly make available to the Trustee a reasonable
supply of Securities that are not in the form of Global Securities. The Trustee
shall be entitled to rely upon any order, direction or request of the Depositary
or its authorized representative which is given or made pursuant to this Article
III if such order, direction or request is given or made in accordance with the
Applicable Procedures.

            (D)    Every Security authenticated and delivered upon registration
of transfer of, or in exchange for or in lieu of, a Global Security or any
portion thereof, whether pursuant to this Article III or otherwise, shall be
authenticated and delivered in the form of, and shall be, a registered Global
Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof, in which case such
Security shall be authenticated and delivered in definitive, fully registered
form, without interest coupons.

                                      -37-

            (E)    The Depositary or its nominee, as registered owner of a
Global Security, shall be the Holder of such Global Security for all purposes
under the Indenture and the Securities, and owners of beneficial interests in a
Global Security shall hold such interests pursuant to the Applicable Procedures.
Accordingly, any such owner's beneficial interest in a Global Security will be
shown only on, and the transfer of such interest shall be effected only through,
records maintained by the Depositary or its nominee or its Agent Members and
such owners of beneficial interests in a Global Security will not be considered
the owners or holders thereof.

     (2)    Non-global Securities. Securities issued upon the events described
in Section 3.4(1)(B) shall be in definitive, fully registered form, without
interest coupons, and shall bear the Restricted Securities Legend if and as
required by this Indenture.

Section 3.5    REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE; RESTRICTIONS
               ON TRANSFER.

     (1)    The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office referred to as
the "Security Register") in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Securities and
of transfers of Securities. The Trustee is hereby appointed "Security Registrar"
for the purpose of registering Securities and transfers and exchanges of
Securities as herein provided.

     Upon surrender for registration of transfer of any Security at an office or
agency of the Company designated pursuant to Section 10.2 for such purpose, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
any authorized denominations and of a like aggregate principal amount and
bearing such restrictive legends as may be required by this Indenture.

     At the option of the Holder, and subject to the other provisions of this
Section 3.5, Securities may be exchanged for other Securities of any authorized
denomination and of a like aggregate principal amount, upon surrender of the
Securities to be exchanged at any such office or agency. Whenever any Securities
are so surrendered for exchange, and subject to the other provisions of this
Section 3.5, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities that the Holder making the exchange is entitled to
receive. Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Security Registrar) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company, the Trustee and the Security Registrar duly
executed, by the Holder thereof or his attorney duly authorized in writing.

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt and entitled to the same benefits under this Indenture as the Securities
surrendered upon such registration of transfer or exchange.

     No service charge shall be made to a Holder for any registration of
transfer or exchange of Securities except as provided in Section 3.6, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section
3.4,

                                      -38-
<Page>

Section 8.5, Section 12.2 or Section 14.4 (other than where the shares of Common
Stock are to be issued or delivered in a name other than that of the Holder of
the Security) not involving any transfer and other than any stamp and other
duties, if any, which may be imposed in connection with any such transfer or
exchange by the United States or any political subdivision thereof or therein,
which shall be paid by the Company.

     In the event of a redemption of the Securities, neither the Company nor the
Securities Registrar will be required (a) to register the transfer of or
exchange Securities for a period of 15 days immediately preceding the date
notice is given identifying the serial numbers of the Securities called for such
redemption or (b) to register the transfer of or exchange any Security, or
portion thereof, called for redemption.

     (2)    CERTAIN TRANSFERS AND EXCHANGES. Notwithstanding any other provision
of this Indenture or the Securities, transfers and exchanges of Securities and
beneficial interests in a Global Security of the kinds specified in this Section
3.5(2) shall be made only in accordance with this Section 3.5(2).

            (A)    RESTRICTED GLOBAL SECURITY TO RESTRICTED NON-GLOBAL SECURITY.
In the event that Non-global Securities are to be issued pursuant to Section
3.4(1)(B) in connection with any transfer of Securities, such transfer may be
effected only in accordance with the provisions of this Clause (2)(i) and
subject to the Applicable Procedures. Upon receipt by the Trustee, as Security
Registrar, of (A) a Company Order from the Company directing the Trustee, as
Security Registrar, to (x) authenticate and deliver one or more Securities of
the same aggregate principal amount as the beneficial interest in the Restricted
Global Security to be transferred, such instructions to contain the name or
names of the designated transferee or transferees, the authorized denomination
or denominations of the Securities to be so issued and appropriate delivery
instructions and (y) decrease the beneficial interest of a specified Agent
Member's account in a Restricted Global Security by a specified principal amount
not greater than the principal amount of such Restricted Global Security, and
(B) such other certifications, legal opinions or other information as the
Company or the Trustee may reasonably require to confirm that such transfer is
being made pursuant to an exemption from, or in a transaction not subject to,
the registration requirements of the Securities Act, then the Trustee, as
Security Registrar, shall decrease the principal amount of the Restricted Global
Security by the specified amount and authenticate and deliver Securities in
accordance with such instructions from the Company as provided in Section
3.4(1)(C).

            (B)    RESTRICTED NON-GLOBAL SECURITY TO RESTRICTED GLOBAL SECURITY.
If the Holder of a Restricted Security (other than a Global Security) wishes at
any time to transfer all or any portion of such Restricted Security to a Person
who wishes to take delivery thereof in the form of a beneficial interest in the
Restricted Global Security, such transfer may be effected only in accordance
with the provisions of this Clause (2)(ii) and subject to the Applicable
Procedures. Upon receipt by the Trustee, as Security Registrar, of such
Restricted Security as provided in Section 3.5(1) and instructions from the
Company directing that a beneficial interest in the Restricted Global Security
in a specified principal amount not greater than the principal amount of such
Security be credited to a specified Agent Member's account, then the Trustee, as
Security Registrar, shall cancel such Restricted Security (and issue a new
Restricted Security in respect of any

                                      -39-
<Page>

untransferred portion thereof) as provided in Section 3.5(1) and increase the
principal amount of the Restricted Global Security by the specified principal
amount as provided in Section 3.4(1)(C).

            (C)    EXCHANGES BETWEEN GLOBAL SECURITY AND NON-GLOBAL SECURITY. A
beneficial interest in a Global Security may be exchanged for a Security that is
not a Global Security only as provided in Section 3.4 or only if such exchange
occurs in connection with a transfer effected in accordance with Clause 2(i)
above, PROVIDED that, if such interest is a beneficial interest in the
Restricted Global Security, then such interest shall be exchanged for a
Restricted Security (subject in each case to Section 3.5(3). A Security that is
not a Global Security may be exchanged for a beneficial interest in a Global
Security only if such exchange occurs in connection with a transfer effected in
accordance with Clause (2)(ii) above.

     (3)    SECURITIES ACT LEGENDS. All Securities issued pursuant to this
Indenture, and all Successor Securities, shall bear the Restricted Securities
Legend and shall be subject to the restrictions on transfer specified therein,
subject to the following:

            (A)    subject to the following Clauses of this Section 3.5(3), a
Security or any portion thereof which is exchanged, upon transfer or otherwise,
for a Global Security or any portion thereof shall bear the Restricted
Securities Legend borne by such Global Security for which the Security was
exchanged;

            (B)    subject to the following Clauses of this Section 3.5(3), a
new Security that is not a Global Security and is issued in exchange for another
Security (including a Global Security) or any portion thereof, upon transfer or
otherwise, shall bear the Restricted Securities Legend borne by the Security for
which the new Security was exchanged;

            (C)    any Securities that are sold or otherwise disposed of
pursuant to an effective registration statement under the Securities Act
(including the Shelf Registration Statement), together with their Successor
Securities shall not bear a Restricted Securities Legend; the Company shall
inform the Trustee in writing of the effective date of any such registration
statement registering the Securities under the Securities Act and shall notify
the Trustee at any time when prospectuses must be delivered with respect to
Securities to be sold pursuant to such registration statement. The Trustee shall
not be liable for any action taken or omitted to be taken by it in good faith in
accordance with the aforementioned registration statement;

            (D)    at any time after the Securities may be freely transferred
without registration under the Securities Act or without being subject to
transfer restrictions pursuant to the Securities Act, a new Security that does
not bear a Restricted Securities Legend may be issued in exchange for or in lieu
of a Security (other than a Global Security) or any portion thereof that bears
such a legend if the Trustee has received an Unrestricted Securities
Certificate, satisfactory to the Trustee and duly executed by the Holder of such
Security bearing a Restricted Securities Legend or his attorney duly authorized
in writing, and after such date and receipt of such certificate, the Trustee
shall authenticate and deliver such new Security in exchange for or in lieu of
such other Security as provided in this Article III;

                                      -40-
<Page>

            (E)    a new Security that does not bear a Restricted Securities
Legend may be issued in exchange for or in lieu of a Security or any portion
thereof that bears such a legend if, in the Company's judgment, placing such a
legend upon such new Security is not necessary to ensure compliance with the
registration requirements of the Securities Act, and the Trustee, at the
direction of the Company, shall authenticate and deliver such a new Security as
provided in this Article III; and

            (F)    notwithstanding the foregoing provisions of this Section
3.5(3), a Successor Security of a Security that does not bear a Restricted
Securities Legend shall not bear such legend unless the Company has reasonable
cause to believe that such Successor Security is a "restricted security" within
the meaning of Rule 144, in which case the Trustee, at the direction of the
Company, shall authenticate and deliver a new Security bearing a Restricted
Securities Legend in exchange for such Successor Security as provided in this
Article.

     (4)    Any stock certificate representing shares of Common Stock issued
upon conversion of the Securities shall bear the Restricted Securities Legend
borne by such Securities, to the extent required by this Indenture, unless such
shares of Common Stock have been sold pursuant to a registration statement that
has been declared effective under the Securities Act (and that continues to be
effective at the time of such transfer) or sold pursuant to Rule 144(k) of the
Securities Act, or unless otherwise agreed by the Company in writing with
written notice thereof to the transfer agent for the Common Stock. With respect
to the transfer of shares of Common Stock issued upon conversion of the
Securities that are restricted hereunder, any deliveries of certificates, legal
opinions or other instruments that would be required to be made to the Security
Registrar in the case of a transfer of Securities, as described above, shall
instead be made to the transfer agent for the Common Stock.

     (5)    Neither the Trustee, the Paying Agent nor any of their agents shall
(i) have any duty to monitor compliance with or with respect to any federal or
state or other securities or tax laws or (ii) have any duty to obtain
documentation on any transfers or exchanges other than as specifically required
hereunder.

Section 3.6    MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES.

     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

     If there be delivered to the Company and to the Trustee:

     (1)    evidence to their satisfaction of the destruction, loss or theft of
any Security, and

     (2)    such security or indemnity as may be satisfactory to the Company and
the Trustee to save each of them and any agent of either of them harmless, then,
in the absence of actual notice to the Company or the Trustee that such Security
has been acquired by a bona fide purchaser, the Company shall execute and the
Trustee shall authenticate and deliver, in lieu of any such destroyed,

                                      -41-
<Page>

lost or stolen Security, a new Security of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion, but
subject to any conversion rights, may, instead of issuing a new Security, pay
such Security, upon satisfaction of the conditions set forth in the preceding
paragraph.

     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto (other than any stamp and other
duties, if any, which may be imposed in connection therewith by the United
States or any political subdivision thereof or therein, which shall be paid by
the Company) and any other expenses (including the fees and expenses of the
Trustee) connected therewith.

     Every new Security issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and such new Security shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Securities duly issued
hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies of any Holder with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.7    PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

     Subject to the last paragraph of this Section, interest or Liquidated
Damages on any Security that is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest.

     Any interest or Liquidated Damages on any Security that is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

     (1)    The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest, which shall be fixed in the following
manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Security, the date of the
proposed payment and the Special Record Date, and at the same time the Company
shall deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed

                                      -42-
<Page>

payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this Clause provided. The
Special Record Date for the payment of such Defaulted Interest shall be not more
than 15 days and not less than 10 days prior to the date of the proposed payment
and not less than 10 days after the receipt by the Trustee of the notice of the
proposed payment. The Trustee, in the name and at the expense of the Company,
shall cause notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor to be mailed, first-class postage prepaid, to each
Holder at such Holder's address as it appears in the Security Register, not less
than 10 days prior to such Special Record Date. Notice of the proposed payment
of such Defaulted Interest and the Special Record Date therefor having been so
mailed, such Defaulted Interest shall be paid to the Persons in whose names the
Securities (or their respective Predecessor Securities) are registered at the
close of business on such Special Record Date and shall no longer be payable
pursuant to the following Clause (2).

     (2)    The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this Clause, such manner of payment shall be deemed
practicable by the Trustee.

     Subject to the foregoing and following provisions of this Section and
Section 3.5, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

     Interest on any Security that is converted in accordance with Section 12.2
during a Record Date Period shall be payable in accordance with the provisions
of Section 12.2.

Section 3.8    PERSONS DEEMED OWNERS.

     Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee, any Paying Agent and any agent of the Company, the Trustee
or any Paying Agent may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of and (subject to Section 3.7) interest on such Security and for all
other purposes whatsoever, whether or not such Security be overdue, and neither
the Company, the Trustee, any Paying Agent nor any agent of the Company, the
Trustee or any Paying Agent shall be affected by notice to the contrary.

Section 3.9    CANCELLATION.

     All Securities surrendered for payment, redemption, repurchase,
registration of transfer or exchange or conversion shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee. All Securities so
delivered to the Trustee shall be canceled promptly by the Trustee (or its
agent). No Securities shall be authenticated in lieu of or in exchange for any
Securities canceled as provided in this Section 3.9. The Trustee shall dispose
of all canceled Securities in accordance with applicable law and its customary
practices in effect from time to time.

                                      -43-
<Page>

Section 3.10   COMPUTATION OF INTEREST.

     Interest on the Securities (including any Liquidated Damages) shall be
computed on the basis of a 360-day year of twelve 30-day months.

Section 3.11   CUSIP NUMBERS.

     The Company in issuing Securities may use "CUSIP" numbers (if then
generally in use) in addition to serial numbers; if so, the Trustee shall use
such CUSIP numbers in addition to serial numbers in notices of redemption and
repurchase as a convenience to Holders; PROVIDED that any such notice may state
that no representation is made as to the correctness of such CUSIP numbers
either as printed on the Securities or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Securities, and any such redemption
or repurchase shall not be affected by any defect in or omission of such CUSIP
numbers.

                           SATISFACTION AND DISCHARGE

Section 4.1    SATISFACTION AND DISCHARGE OF INDENTURE.

     This Indenture shall upon Company Request cease to be of further effect

exchange, or replacement of Securities herein expressly provided for and any
right to receive Liquidated Damages as provided in the Registration Rights
Agreement and in the form of Securities set forth in Section 2.2 and the
Company's obligations to the Trustee pursuant to Section 6.7), and the Trustee,
at the expense of the Company, shall execute proper instruments in form and
substance satisfactory to the Trustee acknowledging satisfaction and discharge
of this Indenture, when

     (1)    either

            (A)    all Securities theretofore authenticated and delivered (other
than (A) Securities which have been destroyed, lost or stolen and that have been
replaced or paid as provided in Section 3.6 and (B) Securities for whose payment
money has theretofore been deposited in trust or segregated and held in trust by
the Company and thereafter repaid to the Company or discharged from such trust,
as provided in Section 10.3) have been delivered to the Trustee for
cancellation; or

            (B)    all such Securities not theretofore delivered to the Trustee
or its agent for cancellation (other than Securities referred to in clauses (A)
and (B) of clause (1)(i) above)

                   (a)    have become due and payable, or

                   (b)    will have become due and payable at their Stated
Maturity within one year, or

                                      -44-

                   (c)    are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name, and at the expense, of the Company,

and the Company, in the case of clause (a), (b) or (c) above, has deposited or
caused to be deposited with the Trustee as trust funds (immediately available to
the Holders in the case of clause (a)) in trust for the purpose an amount in
cash sufficient to pay and discharge the entire indebtedness on such Securities
not theretofore delivered to the Trustee for cancellation, for principal and
interest (including any Liquidated Damages) to the date of such deposit (in the
case of Securities which have become due and payable) or to the Stated Maturity
or Redemption Date, as the case may be;

     (2)    the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

     (3)    the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the

the Company to any Authenticating Agent under Section 6.12, the obligation of

the Trustee pursuant to clause (1)(ii) of this Section, the obligations of the
Trustee under Section 4.2 and the last paragraph of Section 10.3 and the
obligations of the Company and the Trustee under Section 3.5 and Article XII
shall survive.

Section 4.2    APPLICATION OF TRUST MONEY.

     Subject to the provisions of the last paragraph of Section 10.3, all money
deposited with the Trustee pursuant to Section 4.1 shall be held in trust for
the sole benefit of the Holders, and such monies shall be applied by the
Trustee, in accordance with the provisions of the Securities and this Indenture,
to the payment, either directly or through any Paying Agent (including the

principal and interest (including Liquidated Damages, if any) for whose payment
such money has been deposited with the Trustee.

     All moneys deposited with the Trustee pursuant to Section 4.1 (and held by
it or any Paying Agent) for the payment of Securities subsequently converted

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed or assessed against all money deposited with the Trustee

Section 5.1    EVENTS OF DEFAULT.

registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities a written notice specifying such default or breach and
requiring it to be remedied and stating that such notice is a "Notice of
Default" hereunder; or

     (6)    a default in the payment when due (either at its stated maturity or

Section 5.2    ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

     If an Event of Default (other than an Event of Default specified in Section
5.1(7) or Section 5.1(8) with respect to the Company) occurs and is continuing,
then in every such case the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities may declare the principal of all
the Securities to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by the Holders), and upon any such
declaration such principal and all accrued interest thereon shall become
immediately due and payable. If an Event of Default specified in Section 5.1(7)
or Section 5.1(8) with respect to the Company occurs and is continuing, the
principal of, and accrued interest on, all the Securities shall become
immediately due and payable without any declaration or other Act of the Holders
or any act on the part of the Trustee.

     At any time after such declaration of acceleration has been made and before
a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter in this Article provided, the Holders of a majority in
principal amount of the Outstanding Securities, by written notice to the Company
and the Trustee, may, on behalf of all Holders, rescind and annul such
declaration and its consequences if:

                                      -47-
<Page>

     (1)    the Company has paid or deposited with the Trustee a sum sufficient
to pay

            (A)    all overdue interest (including Liquidated Damages, if any)
on all Securities,

            (B)    the principal of any Securities that have become due
otherwise than by such declaration of acceleration and any interest thereon at
the rate borne by the Securities,

            (C)    to the extent permitted by applicable law, interest upon
overdue interest at a rate of 1.00% per annum, and

            (D)    all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel;

     (2)    all Events of Default, other than the nonpayment of the principal of
and interest on Securities which have become due solely by such declaration of
acceleration, have been cured or waived as provided in Section 5.13; and

     (3)    such rescission and annulment would not conflict with any judgment
or decree issued in appropriate judicial proceedings regarding the payment by
the Trustee to the Holders of the amounts referred to in Section 5.2(1).

     No rescission or annulment referred to above shall affect any subsequent
default or impair any right consequent thereon.

Section 5.3    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

     The Company covenants that if:

     (1)    default is made in the payment of any interest (including any
Liquidated Damages) on any Security when it becomes due and payable and such
default continues for a period of 30 days, or

     (2)    default is made in the payment of the principal of any Security at
the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities the whole amount then due and payable on such
Securities for principal and interest (including any Liquidated Damages) and
interest on any overdue principal and, to the extent permitted by applicable
law, on any overdue interest (including any Liquidated Damages), at a rate of
1.00% per annum, and in addition thereto, such further amount as shall be
sufficient to cover the reasonable costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Securities and collect the

                                      -48-
<Page>

moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

     If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

Section 5.4    TRUSTEE MAY FILE PROOFS OF CLAIM.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or the
creditors of either, the Trustee (irrespective of whether the principal of, and
any interest on, the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company for the payment of overdue principal
or interest) shall be entitled and empowered, by intervention in such proceeding
or otherwise,

     (1)    to file and prove a claim for the whole amount of principal and
interest owing and unpaid in respect of the Securities and take such other
actions, including participating as a member, voting or otherwise, of any
official committee of creditors appointed in such matter, and to file such other
papers or documents, in each of the foregoing cases, as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and of the Holders of Securities allowed in
such judicial proceeding, and

     (2)    to collect and receive any moneys or other property payable or
deliverable on any such claim and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder of
Securities to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders of
Securities to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel and any other amounts due the Trustee under Section 6.7.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder of a Security in any such proceeding;
PROVIDED, HOWEVER, that the Trustee may, on behalf of such Holders, vote for the
election of a trustee in bankruptcy or similar official.

                                      -49-

Section 5.5    TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which judgment has been recovered.

Section 5.6    APPLICATION OF MONEY COLLECTED.

     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or interest,
upon presentation of the Securities and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 6.7;

     SECOND: To the payment of the amounts then due and unpaid for principal of
or interest (including Liquidated Damages, if any) on, the Securities in respect
of which or for the benefit of which such money has been collected, ratably,
without preference or priority of any kind, according to the amounts due and
payable on such Securities for principal and interest (including Liquidated
Damages, if any), respectively; and

     THIRD: Any remaining amounts shall be repaid to the Company.

Section 5.7    LIMITATION ON SUITS.

     No Holder of any Security shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder, unless:

     (1)    such Holder has previously given written notice to the Trustee of an
Event of Default that is continuing at the time of such institution;

     (2)    the Holders of not less than 25% in principal amount of the
Outstanding Securities shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder;

     (3)    such Holder or Holders have offered to the Trustee, and if
requested, shall have provided, reasonable indemnity against the costs, expenses
and liabilities to be incurred in compliance with such request;

     (4)    the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity (or if requested, receipt of indemnity) has failed to
institute any such proceeding; and

                                      -50-
<Page>

     (5)    no direction inconsistent with such written request has been given
to the Trustee during such 60 day period by the Holders of a majority in
principal amount of the Outstanding Securities, it being understood and intended
that no one or more of such Holders shall have any right in any manner whatever
by virtue of, or by availing of, any provision of this Indenture to affect,
disturb or prejudice the rights of any other of such Holders, or to obtain or
seek to obtain priority or preference over any other of such Holders or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all such Holders.

Section 5.8    UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND INTEREST
               AND TO CONVERT.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and (subject to Section 3.7) interest (including
Liquidated Damages, if any) on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption or repurchase, on the
Redemption Date or Repurchase Date, as the case may be), and to convert such
Security in accordance with Article XII, and to institute suit for the
enforcement of any such payment and right to convert, and such rights shall not
be impaired without the consent of such Holder.

Section 5.9    RESTORATION OF RIGHTS AND REMEDIES.

     If the Trustee or any Holder of a Security has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders of
Securities shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
such Holders shall continue as though no such proceeding had been instituted.

Section 5.10   RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
3.6, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders of Securities is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

Section 5.11   DELAY OR OMISSION NOT WAIVER.

     No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or any
acquiescence therein. Every right and remedy given by this Article V or by law
to the Trustee or to the Holders of Securities may be exercised from time to

                                      -51-
<Page>

time, and as often as may be deemed expedient, by the Trustee or (subject to the
limitations contained in this Indenture) by the Holders of Securities as the
case may be.

Section 5.12   CONTROL BY HOLDERS OF SECURITIES.

     Subject to Section 6.3, the Holders of a majority in principal amount of
the Outstanding Securities shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, PROVIDED that

     (1)    such direction shall not be in conflict with any rule of law or with
this Indenture, and

     (2)    the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and

     (3)    the Trustee need not take any action that might be unjustly
prejudicial to the Holders of Securities not consenting.

Section 5.13   WAIVER OF PAST DEFAULTS.

     The Holders of not less than a majority in principal amount of the
Outstanding Securities may on behalf of the Holders of all the Securities waive
any past default hereunder and its consequences, except a default (A) in the
payment of the principal of or interest (including Liquidated Damages) on any
Security, or (B) in respect of a covenant or provision hereof which under
Article VIII 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 arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

Section 5.14   UNDERTAKING FOR COSTS.

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or any suit against the Trustee for any action taken, suffered
or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities, or to any suit instituted by any Holder of
any Security for the enforcement of the payment of the principal of or interest
(including Liquidated Damages, if any) on any Security on or after the
respective Stated Maturity or Maturities expressed in such Security (or, in the
case of redemption or repurchase, on or after the Redemption Date or

                                      -52-
<Page>

Repurchase Date, as the case may be) or for the enforcement of the right to
convert any Security in accordance with Article XII.

Section 5.15   WAIVER OF STAY, USURY OR EXTENSION LAWS.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, usury or extension law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede by reason of such law the
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

                                   ARTICLE VI
                                   THE TRUSTEE

Section 6.1    CERTAIN DUTIES AND RESPONSIBILITIES.

     (1)    Except during the continuance of an Event of Default,

            (A)    the Trustee undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture, and no implied covenants
or obligations shall be read into this Indenture against the Trustee; and

            (B)    in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture, but in the case of
any such certificates or opinions which by any provision hereof are specifically
required to be furnished to the Trustee, the Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of
this Indenture, but not to verify the contents thereof.

     (2)    In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

     (3)    No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that

            (A)    this paragraph (3) shall not be construed to limit the effect
of paragraph (1) of this Section;

                                      -53-
<Page>

            (B)    the Trustee shall not be liable for any error of judgment
made in good faith by a Responsible Officer, unless it shall be proved that the
Trustee was negligent in ascertaining the pertinent facts;

            (C)    the Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with the
direction of the Holders of a majority in principal amount of the Outstanding
Securities relating to the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred upon the Trustee, under this Indenture; and

            (D)    no provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

     (4)    Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section and the Trust Indenture Act.

Section 6.2    NOTICE OF DEFAULTS.

     Within 90 days after the occurrence of any default hereunder as to which
the Trustee has received written notice, the Trustee shall give to all Holders
of Securities, in the manner provided in Section 1.6, notice of such default,
unless such default shall have been cured or waived; PROVIDED, HOWEVER, that,
except in the case of a default in the payment of the principal of or interest
(including Liquidated Damages, if any) on any Security the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors or Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Holders; and PROVIDED, FURTHER, that in the
case of any default of the character specified in Section 5.1(5), no such notice
to Holders of Securities shall be given until at least 60 days after the
occurrence thereof or, if applicable, the cure period specified therein. For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, an Event of Default.

Section 6.3    CERTAIN RIGHTS OF TRUSTEE.

     Subject to the provisions of Section 6.1:

     (1)    the Trustee may rely, and shall be protected in acting or refraining
from acting, upon any resolution, Officers' Certificate, other certificate,
statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture, note, coupon, other evidence of indebtedness or other
paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

                                      -54-
<Page>

     (2)    any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors shall be sufficiently evidenced by a Board Resolution;

     (3)    whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be the one specifically prescribed) may, in the absence of bad faith on its
part, request and rely upon an Officers' Certificate or Opinion of Counsel;

     (4)    the Trustee may consult with counsel of its selection and the advice
of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

     (5)    the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders of Securities pursuant to this Indenture, unless such Holders
shall have offered, and, if requested by the Trustee, delivered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction;

     (6)    the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, coupon, other evidence of indebtedness or other paper or document, but the
Trustee may make such further inquiry or investigation into such facts or
matters as it may see fit, and, if the Trustee shall determine to make such
further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Company, personally or by agent or attorney; and

     (7)    the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder.

Section 6.4    NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

     The recitals contained herein and in the Securities (except the Trustee's
certificates of authentication) shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for their correctness. The Trustee
makes no representations as to the validity or sufficiency of this Indenture, of
the Securities or of the Common Stock issuable upon the conversion of the
Securities. The Trustee shall not be accountable for the use or application by
the Company of Securities or the proceeds thereof.

Section 6.5    MAY HOLD SECURITIES, ACT AS TRUSTEE UNDER OTHER INDENTURES.

     The Trustee, any Authenticating Agent, any Paying Agent, any Conversion
Agent or any other agent of the Company or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities and may otherwise
deal with the Company with the same rights it

                                      -55-
<Page>

would have if it were not Trustee, Authenticating Agent, Paying Agent,
Conversion Agent or such other agent.

     The Trustee may become and act as trustee under other indentures under
which other securities, or certificates of interest or participation in other
securities, of the Company are outstanding in the same manner as if it were not
Trustee hereunder.

Section 6.6    MONEY HELD IN TRUST.

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed in writing with the Company.

Section 6.7    COMPENSATION AND REIMBURSEMENT.

     The Company agrees:

     (1)    to pay to the Trustee from time to time such reasonable compensation
as the Company and the Trustee shall from time to time agree in writing for its
acceptance of this Indenture and for all services rendered by it hereunder
(which compensation shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust);

     (2)    except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this
Indenture (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

     (3)    to indemnify the Trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of this
trust, including the reasonable costs, expenses and reasonable attorneys' fees
of defending itself against any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder.

     The Trustee shall have a lien prior to the Securities on all money or
property held or controlled by the Trustee to secure the Company's payment
obligations in this Section 6.7, except that held in trust to pay principal and
interest (including Liquidated Damages) on the Securities.

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(7) or Section 5.1(8), the expenses
(including the reasonable charges of its counsel) and the compensation for the
services are intended to constitute expenses of the administration under any
applicable Federal or state bankruptcy, insolvency or other similar law.

     The provisions of this Section shall survive the termination of this
Indenture or the earlier resignation or removal of the Trustee.

Section 6.8    CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

     There shall at all times be a Trustee hereunder which shall be a Person
that is eligible pursuant to the Trust Indenture Act to act as such, having (or
be part of a holding company group with) a combined capital and surplus of at
least U.S. $10,000,000, subject to supervision or examination by federal or
state authority, and in good standing. The Trustee or an Affiliate of the
Trustee shall maintain an established place of business in the Borough of
Manhattan, The City of New York. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of said

Section 6.9    RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     (1)    No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.10.

     (2)    The Trustee may resign at any time by giving written notice thereof
to the Company. If the instrument of acceptance by a successor Trustee required

after the giving of such notice of resignation, the resigning Trustee may

Trustee.

     (3)    The Trustee may be removed at any time by an Act of the Holders of a
majority in principal amount of the Outstanding Securities, delivered to the

            (B)    the Trustee shall become incapable of acting or shall be
adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property

Trustee or of its property or affairs for the purpose of rehabilitation,

then, in any such case (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 5.14, any Holder of a Security who has been
a bona fide Holder of a Security for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent

delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance

deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,

Company shall execute any and all instruments for more fully and certainly

conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee (including the trust created by this Indenture), shall
be the successor of the Trustee hereunder, PROVIDED such corporation shall be
otherwise eligible under this Article, without the execution or filing of any
paper or any further act on the part of any of the parties hereto. In case any
Securities shall have been authenticated, but not delivered, by the Trustee then
in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

Section 6.12   AUTHENTICATING AGENTS.

     The Trustee may, with the consent of the Company, appoint an Authenticating
Agent or Agents acceptable to the Company with respect to the Securities, which
Authenticating Agent shall be authorized to act on behalf of the Trustee to
authenticate Securities issued upon exchange or substitution pursuant to this
Indenture.

     Securities authenticated by an Authenticating Agent shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder, and every reference in
this Indenture to the authentication and delivery of Securities by the Trustee
or the Trustee's certificate of authentication shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be subject to acceptance
by the Company and shall at all times be a corporation organized and doing
business under the laws of the United States of America, any State thereof or
the District of Columbia, authorized under such laws to act as Authenticating
Agent and subject to supervision or examination by government or other fiscal
authority. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 6.12, such Authenticating Agent
shall resign immediately in the manner and with the effect specified in this
Section 6.12.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, PROVIDED such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such

                                      -59-
<Page>

Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be subject to acceptance by the Company. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

     The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section.

If an Authenticating Agent is appointed with respect to the Securities pursuant
to this Section, the Securities may have endorsed thereon, in addition to or in
lieu of the Trustee's certification of authentication, an alternative
certificate of authentication in the following form:
This is one of the Securities referred to in the within-mentioned Indenture.

of the Company for each of the aforesaid purposes.

Section 10.3   MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST.

     If the Company shall act as its own Paying Agent, it will, on or before
each due date of the principal of or interest (including Liquidated Damages, if
any) on any of the Securities, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum sufficient to pay the principal or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and the Company will promptly notify the Trustee
of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents, it will, no
later than the opening of business on each due date of the principal of or
interest on any Securities, deposit with the Trustee a sum in funds immediately
payable on the payment date sufficient to pay the principal or interest so
becoming due, such sum to be held for the benefit of the Persons entitled to
such principal or interest, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of any failure so to act.

     The Company will cause each Paying Agent other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section, that such Paying
Agent will:

     (1)    hold all sums held by it for the payment of the principal of or
interest on Securities for the benefit of the Persons entitled thereto until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided;

     (2)    give the Trustee notice of any default by the Company (or any other
obligor upon the Securities) in the making of any payment of principal or
interest; and

     (3)    at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held by
such Paying Agent.

                                      -67-
<Page>

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of or interest on any
Security and remaining unclaimed for two years after such principal or interest
has become due and payable shall be paid within 60 days of such date by the
Trustee to the Company on Company Request as its property free from trust, or
(if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease.

Section 10.4   EXISTENCE.

     Subject to Article VII, the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence, rights
(charter and statutory) and franchises; PROVIDED, HOWEVER, that the Company
shall not be required to preserve any such right or franchise if the Company
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the Holders.

Section 10.5   STATEMENT BY OFFICERS AS TO DEFAULT.

     The Company shall deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

     The Company will deliver to the Trustee, forthwith upon becoming aware of
any default or any Event of Default under the Indenture, an Officers'
Certificate specifying with particularity such default or Event of Default and
further stating what action the Company has taken, is taking or proposes to take
with respect thereto. For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default.

     Any notice required to be given under this Section shall be delivered to
the Trustee at its Corporate Trust Office.

Section 10.6   DELIVERY OF CERTAIN INFORMATION.

     At any time when the Company is not subject to Section 13 or 15(d) of the
Exchange Act, upon the request of a Holder of a Restricted Security or the
holder of shares of Common Stock issued upon conversion thereof, the Company
will promptly furnish or cause to be furnished Rule 144A Information (as defined
below) to such Holder of Restricted Securities or such holder of shares of
Common Stock issued upon conversion of Restricted Securities, or to a
prospective purchaser of any such security designated by any such Holder or
holder, as the case may be, to the extent required to permit compliance by such
Holder or holder with Rule 144A under the Securities Act (or any successor
provision thereto) in connection with the resale of any such security; PROVIDED,
HOWEVER, that the Company shall not be required to furnish such information in
connection with any request made on or after the date that is two years from the
later of (i) the date such a security (or any such predecessor security) was
last acquired from the Company or (ii) the date such a security (or any such
predecessor security) was last acquired from an "affiliate" of the Company
within the meaning of Rule 144 under the Securities Act (or any successor
provision thereto). "Rule 144A Information" shall be such information as is
specified pursuant to Rule 144A(d)(4) under the Securities Act (or any successor
provision thereto).

Section 10.7   RESALE OF CERTAIN SECURITIES.

     During the period beginning on the last date of original issuance of the
Securities and ending on the date that is two years from such date (or such
shortened period under Rule 144(k) under the Securities Act or any successor
rule), the Company will not, and will not permit any of its subsidiaries or
other "affiliates" (as defined under Rule 144 under the Securities Act or any
successor provision thereto) to, resell (i) any Securities that constitute
"restricted securities" under Rule 144 or (ii) any securities into which the
Securities have been converted under this Indenture that constitute "restricted
securities" under Rule 144, that in either case have been reacquired by any of
them. The Trustee shall have no responsibility in respect of the Company's
performance of its agreement in the preceding sentence.

Section 10.8   REGISTRATION RIGHTS.

     The Company agrees that the Holders from time to time of Registrable
Securities (as defined below) are entitled to the benefits of a Registration
Rights Agreement, dated as of August 1, 2003 (the "Registration Rights
Agreement"), executed by the Company as it may be amended from time to time in
accordance with its terms.

     Whenever in this Indenture there is mentioned, in any context, the payment
of the principal of or interest on, or in respect of, any Security, such mention
shall be deemed to include mention of the payment of Liquidated Damages provided
for in this Section to the extent that, in such context, Liquidated Damages are,
were or would be payable in respect thereof pursuant to the provisions of this
Section and express mention of the payment of Liquidated Damages (if applicable)
in any provisions hereof shall not be construed as excluding Liquidated Damages
in those provisions hereof where such express mention is not made.

                                      -69-
<Page>

     For the purposes of the Registration Rights Agreement, "Registrable
Securities" means all or any portion of the Securities issued from time to time
under this Indenture in registered form and the shares of Common Stock issuable
upon conversion, repurchase or redemption of such Securities; PROVIDED, HOWEVER,
that a security ceases to be a Registrable Security when it is no longer a
Restricted Security.

     If a Security, or the shares of Common Stock issuable upon conversion of a
Security, is a Registrable Security, and the Holder thereof elects to sell such
Registrable Security pursuant to the Shelf Registration Statement then, by its
acceptance thereof, the Holder of such Registrable Security will have agreed to
be bound by the terms of the Registration Rights Agreement relating to the
Registrable Securities which are the subject of such election.

     For the purposes of the Registration Rights Agreement, the term "Holder"
includes any Person that has a beneficial interest in any Restricted Global
Security or any beneficial interest in a global security representing shares of
Common Stock issuable upon conversion of a Security.

     If Liquidated Damages are payable under the Registration Rights Agreement,
the Company shall deliver to the Trustee a certificate to that effect stating
(i) the amount of Liquidated Damages that is payable and (ii) the date on which
Liquidated Damages are payable. Unless and until a Responsible Officer of the
Trustee receives at the Corporate Trust Office such a certificate, the Trustee
may assume without inquiry that no Liquidated Damages are payable. If Liquidated
Damages have been paid by the Company directly to the persons entitled to them,
the Company shall deliver to the Trustee a certificate setting forth the
particulars of such payment.

Section 10.9   WAIVER OF CERTAIN COVENANTS.

     The Company may omit in any particular instance to comply with any covenant
or condition set forth in Section 10.4 (other than with respect to the existence
of the Company (subject to Article VII)) and Section 10.7, if before the time
for such compliance the Holders of not less than a majority in principal amount
of the Outstanding Securities, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
or any Paying or Conversion Agent in respect of any such covenant or condition
shall remain in full force and effect.

                                   ARTICLE XI
                            REDEMPTION OF SECURITIES

Section 11.1   RIGHT OF REDEMPTION.

     The Securities may be redeemed in accordance with the provisions of the
form of Securities set forth in Section 2.2.

                                      -70-
<Page>

Section 11.2   APPLICABILITY OF ARTICLE.

     Redemption of Securities at the election of the Company or otherwise, as
permitted or required by any provision of the Securities or this Indenture,
shall be made in accordance with such provision and this Article.

Section 11.3   ELECTION TO REDEEM; NOTICE TO TRUSTEE.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution. In case of any redemption at the election of the Company of
any of the Securities, the Company shall, at least 45 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee in writing of such Redemption
Date.

Section 11.4   SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

     If less than all the Securities are to be redeemed, the particular
Securities to be redeemed shall be selected by the Trustee within five Business
Days after it receives the notice described in Section 11.3, from the
Outstanding Securities not previously called for redemption, by lot or by such
other method as the Trustee may deem fair and appropriate.

     If any Security selected for partial redemption is converted in part before
termination of the conversion right with respect to the portion of the Security
so selected, the converted portion of such Security shall be deemed (so far as
may be) to be the portion selected for redemption. Securities which have been
converted during a selection of Securities to be redeemed may be treated by the
Trustee as Outstanding for the purpose of such selection. The Trustee shall
promptly notify the Company and each Security Registrar in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.

Section 11.5   NOTICE OF REDEMPTION.

     Notice of redemption shall be given by the Company in the manner provided
in Section 1.6 to the Holders of Securities to be redeemed not less than 30 nor
more than 60 days prior to the Redemption Date, and such notice shall be
irrevocable. The Company shall, concurrently with the giving of such notice,
publish a Press Release including the information required to be included in
such notice of redemption hereunder.

     All notices of redemption shall state:

     (1)    the Redemption Date,

                                      -71-
<Page>

     (2)    the Redemption Price, and accrued but unpaid interest (including
Liquidated Damages, if any), if any, to, but excluding, the Redemption Date,

     (3)    if less than all Outstanding Securities are to be redeemed, the
aggregate principal amount of Securities to be redeemed and the aggregate
principal amount of Securities which will be outstanding after such partial
redemption,

     (4)    that on the Redemption Date the Redemption Price, and accrued but
unpaid interest (including Liquidated Damages, if any), if any, to, but
excluding, the Redemption Date, will become due and payable upon each such
Security to be redeemed, and that interest thereon shall cease to accrue on and
after said date,

     (5)    the Conversion Rate, the date on which the right to convert the
Securities to be redeemed will terminate and the places where such Securities
may be surrendered for conversion, and

     (6)    the place or places where such Securities are to be surrendered for
payment of the Redemption Price and accrued interest (including Liquidated
Damages, if any), if any, to, but excluding, the Redemption Date.

     In case of a partial redemption, the notice shall specify the serial and
CUSIP numbers (if any) and the portions thereof called for redemption and that
transfers and exchanges may occur on or prior to the Redemption Date.

     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's written request, by
the Trustee in the name of and at the expense of the Company. Notice of
redemption of Securities to be redeemed at the election of the Company received
by the Trustee shall be given by the Trustee to each Paying Agent in the name of
and at the expense of the Company.

Section 11.6   DEPOSIT OF REDEMPTION PRICE.

     On or prior to the Redemption Date, the Company shall deposit with the
Trustee (or, if the Company is acting as its own Paying Agent, segregate and
hold in trust as provided in Section 10.3) an amount of money (which shall be in
immediately available funds on such Redemption Date) sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest (including Liquidated Damages, if any) to the
Redemption Date on, all the Securities which are to be redeemed on that date
other than any Securities called for redemption on that date which have been
converted prior to the date of such deposit.

     If any Security called for redemption is converted, any money deposited
with the Trustee or so segregated and held in trust for the redemption of such
Security shall (subject to any right of the Holder of such Security or any
Predecessor Security to receive interest as provided in the last paragraph of
Section 3.7) be paid to the Company on Company Request or, if then held by the
Company, shall be discharged from such trust.

                                      -72-
<Page>

Section 11.7   SECURITIES PAYABLE ON REDEMPTION DATE.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified and from and after such date (unless the
Company shall default in the payment of the Redemption Price, including accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
Security for redemption in accordance with said notice such Security shall be
paid by the Company at the Redemption Price together with accrued and unpaid
interest (including Liquidated Damages, if any) to but excluding the Redemption
Date; PROVIDED, HOWEVER, that installments of interest on Securities whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such on the relevant Record Date according to their terms and the provisions of
Section 3.7.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal amount of and, to the extent permitted by
applicable law, accrued interest on such Security shall, until paid, bear
interest from the Redemption Date at a rate of 1.00% per annum and such Security
shall remain convertible until the Redemption Price of such Security (or portion
thereof, as the case may be) shall have been paid or duly provided for.

     Any Security that is to be redeemed only in part shall be surrendered at
the Corporate Trust Office or an office or agency of the Company designated for
that purpose pursuant to Section 10.2 (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and make available for delivery to the Holder of
such Security without service charge, a new Security or Securities, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered. Upon redemption, interests in Global Securities
shall be reduced in accordance with the Applicable Procedures.

Section 11.8   CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION.

     In connection with any redemption of Securities, the Company may arrange
for the purchase and conversion of any Securities by an agreement with one or
more investment bankers or other purchasers (the "Purchasers") to purchase such
securities by paying to the Trustee in trust for the Holders, on or before the
Redemption Date, an amount not less than the applicable Redemption Price,
together with any interest accrued and unpaid to but excluding the Redemption
Date, of such Securities. Notwithstanding anything to the contrary contained in
this Article, the obligation of the Company to pay the Redemption Price,
together with any interest accrued and unpaid to but excluding the Redemption
Date, shall be deemed to be satisfied and discharged to the extent such amount
is so paid by such Purchasers. If such an agreement is entered into (a copy of
which shall be filed with the Trustee prior to the close of business on the
Business Day immediately prior to the Redemption Date), any Securities called
for redemption that are not duly surrendered for conversion by the Holders
thereof may, at the option of the Company, be deemed, to the fullest extent
permitted by law, and consistent with any agreement or agreements with such
Purchasers, to be acquired by

                                      -73-
<Page>

such Purchasers from such Holders and (notwithstanding anything to the contrary
contained in Article XII) surrendered by such Purchasers for conversion, all as
of immediately prior to the close of business on the Redemption Date (and the
right to convert any such Securities shall be extended through such time),
subject to payment of the above amount as aforesaid. At the direction of the
Company, the Trustee shall hold and dispose of any such amount paid to it by the
Purchasers to the Holders in the same manner as it would monies deposited with
it by the Company for the redemption of Securities. Without the Trustee's prior
written consent, no arrangement between the Company and such Purchasers for the
purchase and conversion of any Securities shall increase or otherwise affect any
of the powers, duties, responsibilities or obligations of the Trustee as set
forth in this Indenture, and the Company agrees to indemnify the Trustee from,
and hold it harmless against, any loss, liability or expense arising out of or
in connection with any such arrangement for the purchase and conversion of any
Securities between the Company and such Purchasers, including the costs and
expenses, including reasonable legal fees, incurred by the Trustee in the
defense of any claim or liability arising out of or in connection with the
exercise or performance of any of its powers, duties, responsibilities or
obligations under this Indenture.

                                   ARTICLE XII
                            CONVERSION OF SECURITIES

Section 12.1   CONVERSION PRIVILEGE AND CONVERSION RATE.

     (a)    Subject to and upon compliance with the provisions of this Article,
at the option of the Holder thereof, any Security (or any portion thereof equal
to $1,000 or any integral multiple of $1,000 in excess thereof) may be converted
into fully paid and nonassessable shares (calculated as to each conversion to
the nearest 1/100th of a share) of Common Stock of the Company at the Conversion
Rate, determined as hereinafter provided, in effect at the time of conversion
and subject to the adjustments described below, as follows:

     (1)    if, on or prior to August 1, 2008, the Closing Price Per Share of
the Common Stock for at least 20 Trading Days in the period of the 30
consecutive Trading Days ending on the first day of a Conversion Period was more
than 110% of the then current Conversion Price, then the Holder thereof will be
entitled to convert such Security during that Conversion Period;

     (2)    if, on any date after August 1, 2008 and prior to the Stated
Maturity, the Closing Price Per Share of the Common Stock is more than 110% of
the then current Conversion Price, then the Holder thereof will be entitled to
convert such Security at all times thereafter;

     (3)    if the Company distributes to all or substantially all holders of
Common Stock rights, options or warrants entitling them to purchase Common Stock
at less than the Closing Price Per Share of the Common Stock on the last Trading
Day preceding the declaration of such distribution, then the Holder thereof will
be entitled to convert such Security during the period specified in this
Section;

     (4)    if the Company distributes to all or substantially all holders of
Common Stock cash, assets, debt securities or capital stock, which distribution
has a per share value as determined by the Board of Directors exceeding 5% of
the Closing Price Per Share of the Common Stock on the last

                                      -74-
<Page>

Trading Day preceding the declaration for such distribution, then the Holder
thereof will be entitled to convert such Security during the period specified in
this Section; or

     (5)    if the Company becomes a party to a consolidation, merger or sale of
all or substantially all of the Company's assets where such consolidation,
merger or sale of all or substantially all of the Company's assets constitutes a
Change in Control, then the Holder thereof will be entitled to convert such
Security during the period specified in this Section.

     A "Conversion Period" for the Securities is the period from and including
the eleventh Trading Day in any fiscal quarter of the Company to, but excluding,
the eleventh Trading Day of the immediately following fiscal quarter.

     In the case of a distribution contemplated by clauses (3) and (4) of this
subsection (a), the Company will notify Holders at least 20 days prior to the
ex-dividend date for such distribution (the "Distribution Notice"). Once the
Company has given the Distribution Notice, Holders may surrender their
Securities for conversion at any time until the earlier of the close of business
on the last Business Day preceding the ex-dividend date or the Company's
announcement that such distribution will not take place. Notwithstanding the
foregoing, in the event of a distribution contemplated by clauses (3) and (4) of
this subsection (a), Holders may not convert the Securities if the Holders may
participate in such distribution without converting their Securities. In the
event of a consolidation, merger or sale of all or substantially all of the
Company's assets as contemplated by clause (5) of this subsection (a), the
Company will notify Holders at least 20 days prior to the anticipated closing
date of such transaction (the "Merger Notice"). Once the Company has given the
Merger Notice, the Holders may, in the event of such consolidation, merger or
sale of all or substantially all of the Company's assets, surrender Securities
for conversion at any time from and after the date which is 15 days prior to the
anticipated closing date of such transaction until the date which is 15 days
after the actual closing date of such transaction.

     With respect to clause (1) of this subsection (a), the Conversion Agent
will determine, on behalf of the Company, on the first Business Day succeeding
the first day of the Conversion Period whether the Securities are convertible as
set forth in such clause (1) as a result of the Closing Price Per Share of the
Common Stock and the then current Conversion Price and, if so, will notify the
Company. With respect to clause (2) of this subsection (a), the Conversion Agent
will determine, on behalf of the Company, daily on any date after August 1,
2008, whether the Securities are convertible as set forth in such clause (2) as
a result of the Closing Price Per Share of the Common Stock and the then current
Conversion Price and, if so, will notify the Company.

     (b)    Subject to the further provisions of this Article, a Holder of a
Security may also convert the principal amount of such Security (or any portion
thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof)
into fully paid and nonassessable shares (calculated as to each conversion to
the nearest 1/100th of a share) of Common Stock for the five Business Day period
after any five consecutive Trading Day period in which the average Trading
Prices for the Securities for such five Trading Day period was less than 95% of
the average Conversion Value for the Securities during such period; PROVIDED,
HOWEVER, if on the Conversion Date, the Closing Price Per Share of Common Stock
is greater than the then current Conversion Price and less than or equal to 110%
of

                                      -75-
<Page>

the then current Conversion Price, a Holder surrenders its Securities for
conversion and the Securities are not otherwise convertible, then such Holder
will receive, at the Company's option, cash, Common Stock or a combination of
cash and Common Stock with a value equal to the principal amount of such
Holder's Securities on such Conversion Date. If the Company elects to pay the
Holder in Common Stock or in a combination of cash and Common Stock, the Company
will notify the Holder in writing, and the Common Stock will be valued at 100%
of the average Closing Price Per Share of Common Stock for the five Trading Days
immediately following the Conversion Date.

     The "Conversion Value" for the Securities is equal to the product of (i)
the Closing Price Per Share of the Common Stock on a given day and (ii) the then
current Conversion Rate.

     The "Trading Price" of the Securities on any Trading Day means the average
of the secondary market bid quotations per Security obtained by the Conversion
Agent for $5,000,000 principal amount of the Securities at approximately 3:30
p.m., New York City time, on such Trading Day from an independent nationally
recognized securities dealer the Company selects; PROVIDED that if the
Conversion Agent cannot reasonably obtain a bid for $5,000,000 principal amount
of the Securities from a nationally recognized securities dealer or if in the
Company's reasonable judgment, the bid quotations are not indicative of the
secondary market value of the Securities, then the Trading Price of the
Securities will be deemed to be equal to the product of the then current
Conversion Rate and the Closing Price Per Share of Common Stock on such Trading
Day.

     The Conversion Agent shall have no obligation to determine the Trading
Price of the Securities unless the Company has requested such determination; and
the Company shall have no obligation to make such request unless a Holder
provides the Company with reasonable evidence that the Trading Price of the
Securities is reasonably likely to be less than 95% of the Conversion Value; at
which time, the Company shall instruct the Conversion Agent to determine the
Trading Price of the Securities beginning on the next Trading Day and on each
successive Trading Day until the Trading Price is greater than or equal to 95%
of the Conversion Value.

     (c)   The conversion right, subject to the conditions described in
subsections (a) and (b) of this Section, shall commence on the initial issuance
date of the Securities and expire at the close of business on the date of
Maturity, subject, in the case of conversion of any Global Security, to any
Applicable Procedures. In case a Security or portion thereof is called for
redemption at the election of the Company or the Holder thereof exercises his
right to require the Company to repurchase the Security, such conversion right
in respect of the Security, or portion thereof so called, shall expire at the
close of business on the Business Day immediately preceding the Redemption Date
or the Repurchase Date, as the case may be, unless the Company defaults in
making the payment due upon redemption or repurchase, as the case may be (in
each case subject as aforesaid to any Applicable Procedures with respect to any
Global Security).

     Provisions of this Indenture that apply to conversion of all of a Security
also apply to conversion of a portion of a Security.

                                      -76-
<Page>

     A Holder of Securities is not entitled to any rights of a holder of Common
Stock until such Holder has converted its Securities into Common Stock, and only
to the extent such Securities are deemed to have been converted into Common
Stock pursuant to this Article.

     The rate at which shares of Common Stock shall be delivered upon conversion
(herein called the "Conversion Rate") shall be initially 25.0000 shares of
Common Stock for each U.S.$1,000 principal amount of Securities. The Conversion
Rate shall be adjusted in certain instances as provided in this Article.

Section 12.2   EXERCISE OF CONVERSION PRIVILEGE.

     In order to exercise the conversion privilege, the Holder of any Security
to be converted shall surrender such Security, duly endorsed in blank, at any
office or agency of the Company maintained for that purpose pursuant to Section
10.2, accompanied by a duly signed conversion notice substantially in the form
set forth in Section 2.4 stating that the Holder elects to convert such Security
or, if less than the entire principal amount thereof is to be converted, the
portion thereof to be converted. Each Security surrendered for conversion (in
whole or in part) during the Record Date Period shall (except in the case of any
Security or portion thereof which has been called for redemption on a Redemption
Date, or is repurchasable on a Repurchase Date, occurring, in either case,
within such Record Date Period and, as a result, the right to convert such
Security would otherwise terminate in such period if not exercised) be
accompanied by payment in New York Clearing House funds or other funds
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the principal amount of such Security (or part thereof,
as the case may be) being surrendered for conversion. The interest so payable on
such Interest Payment Date with respect to any Security (or portion thereof, if
applicable) that is surrendered for conversion during the Record Date Period
shall be paid to the Holder of such Security as of such Regular Record Date in
an amount equal to the interest that would have been payable on such Security if
such Security had been converted as of the close of business on such Interest
Payment Date. Interest payable on any Interest Payment Date in respect of any
Security surrendered for conversion on or after such Interest Payment Date shall
be paid to the Holder of such Security as of the Regular Record Date next
preceding such Interest Payment Date, notwithstanding the exercise of the right
of conversion. Except as provided in this paragraph and subject to the last
paragraph of Section 3.7, no cash payment or adjustment shall be made upon any
conversion on account of any interest accrued from the Interest Payment Date
next preceding the conversion date, in respect of any Security (or part thereof,
as the case may be) surrendered for conversion, or on account of any dividends
on the Common Stock issued upon conversion. The Company's delivery to the Holder
of the number of shares of Common Stock (and cash in lieu of fractions thereof,
as provided in this Indenture) into which a Security is convertible will be
deemed to satisfy the Company's obligation to pay the principal amount of the
Security.

     Securities shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Securities for conversion in
accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time. As

                                      -77-
<Page>

promptly as practicable on or after the Conversion Date, the Company shall issue
and deliver to the Trustee, for delivery to the Holder (unless a different
Person is indicated on the Conversion Notice), a certificate or certificates for
the number of full shares of Common Stock issuable upon conversion, together
with payment in lieu of any fraction of a share, as provided in Section 12.3.

     All shares of Common Stock delivered upon such conversion of Restricted
Securities shall bear restrictive legends substantially in the form of the
legends required to be set forth on the Restricted Securities pursuant to
Section 3.5 and shall be subject to the restrictions on transfer provided in
such legends. Neither the Trustee nor any agent maintained for the purpose of
such conversion shall have any responsibility for the inclusion or content of
any such restrictive legends on such Common Stock; PROVIDED, HOWEVER, that the
Trustee or any agent maintained for the purpose of such conversion shall have
provided, to the Company or to the Company's transfer agent for such Common
Stock, prior to or concurrently with a request to the Company to deliver such
Common Stock, written notice that the Securities delivered for conversion are
Restricted Securities.

     In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in an aggregate principal amount equal to
the unconverted portion of the principal amount of such Security. A Security may
be converted in part, but only if the principal amount of such Security to be
converted is any integral multiple of $1,000 and the principal amount of such
security to remain Outstanding after such conversion is equal to $1,000 or any
integral multiple of $1,000 in excess thereof.

     If shares of Common Stock to be issued upon conversion of a Restricted
Security, or Securities to be issued upon conversion of a Restricted Security in
part only, are to be registered in a name other than that of the beneficial
owner of such Restricted Security, then such Holder must deliver to the
Conversion Agent a Surrender Certificate, dated the date of surrender of such
Restricted Security and signed by such beneficial owner, as to compliance with
the restrictions on transfer applicable to such Restricted Security. Neither the
Trustee nor any Conversion Agent, Registrar or Transfer Agent shall be required
to register in a name other than that of the beneficial owner, shares of Common
Stock or Securities issued upon conversion of any such Restricted Security not
so accompanied by a properly completed Surrender Certificate.

Section 12.3   FRACTIONS OF SHARES.

     No fractional shares of Common Stock shall be issued upon conversion of any
Security or Securities. If more than one Security shall be surrendered for
conversion at one time by the same Holder, the number of full shares which shall
be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Securities (or specified portions thereof) so
surrendered. Instead of any fractional share of Common Stock that would
otherwise be issuable upon conversion of any Security or Securities (or
specified portions thereof), the Company shall calculate and pay a cash
adjustment in respect of such fraction (calculated to the nearest 1/100th of a
share) in an amount equal to the same fraction of the Closing Price Per Share at
the close of business on the day of conversion.

                                      -78-

Section 12.4   ADJUSTMENT OF CONVERSION RATE.

     The Conversion Rate shall be subject to adjustments from time to time as
follows:

     (1)    In case the Company shall pay or make a dividend or other
distribution on shares of Common Stock payable in shares of Common Stock, the
Conversion Rate in effect at the opening of business on the day following the
date fixed for the determination of stockholders entitled to receive such
dividend or other distribution shall be increased by dividing such Conversion
Rate by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding at the close of business on the date fixed for such
determination and the denominator shall be the sum of such number of shares and
the total number of shares constituting such dividend or other distribution,
such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. If, after any such date
fixed for determination, any dividend or distribution is not in fact paid, the
Conversion Rate shall be immediately readjusted, effective as of the date the
Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would have been in effect if such determination date had
not been fixed. For the purposes of this paragraph (1), the number of shares of
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company but shall include shares issuable in respect of scrip
certificates issued in lieu of fractions of shares of Common Stock. The Company
will not pay any dividend or make any distribution on shares of Common Stock
held in the treasury of the Company.

     (2)    In case the Company shall issue rights, options or warrants to all
holders of its Common Stock entitling them to subscribe for or purchase shares
of Common Stock at a price per share less than the current market price per
share (determined as provided in paragraph (8) of this Section) of the Common
Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than any rights, options or
warrants that by their terms will also be issued to any Holder upon conversion
of a Security into shares of Common Stock without any action required by the
Company or any other Person), the Conversion Rate in effect at the opening of
business on the day following the date fixed for such determination shall be
increased by dividing such Conversion Rate by a fraction of which the numerator
shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination plus the number of shares of
Common Stock that the aggregate of the offering price of the total number of
shares of Common Stock so offered for subscription or purchase would purchase at
such current market price and the denominator shall be the number of shares of
Common Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination. If, after any such date fixed for determination, any such rights,
options or warrants are not in fact issued, or are not exercised prior to the
expiration thereof, the Conversion Rate shall be immediately readjusted,
effective as of the date such rights, options or warrants expire, or the date
the Board of Directors determines not to issue such rights, options or warrants,
to the Conversion Rate that would have been in effect if the unexercised rights,
options or warrants had never been granted or such determination date had not
been fixed, as the case may be. For the purposes of this paragraph (2), the
number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the

                                      -79-
<Page>

Company but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock. The Company will not
issue any rights, options or warrants in respect of shares of Common Stock held
in the treasury of the Company.

     (3)    In case outstanding shares of Common Stock shall be subdivided into
a greater number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the day following the day upon which such subdivision
becomes effective shall be proportionately increased, and, conversely, in case
outstanding shares of Common Stock shall be combined into a smaller number of
shares of Common Stock, the Conversion Rate in effect at the opening of business
on the day following the day upon which such subdivision or combination becomes
effective shall be proportionately reduced, such increase or reduction, as the
case may be, to become effective immediately after the opening of business on
the day following the day upon which such subdivision or combination becomes
effective.

     (4)    In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock evidences of its indebtedness, shares of any
class of capital stock or other property (including cash or assets or
securities, but excluding (i) any rights, options or warrants referred to in
paragraph (2) of this Section, (ii) any dividend or distribution paid
exclusively in cash referred to in paragraph (5) of this Section, (iii) any
dividend or distribution referred to in paragraph (1) of this Section and (iv)
any consideration distributed in any merger or consolidation to which Section
12.11 applies), the Conversion Rate shall be adjusted so that the same shall
equal the rate determined by dividing the Conversion Rate in effect immediately
prior to the close of business on the date fixed for the determination of
stockholders entitled to receive such distribution by a fraction of which the
numerator shall be the current market price per share (determined as provided in
paragraph (8) of this Section) of the Common Stock on the date fixed for such
determination less the then fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution filed with the Trustee) of the portion of the assets, shares or
evidences of indebtedness so distributed applicable to one share of Common Stock
and the denominator shall be such current market price per share of the Common
Stock, such adjustment to become effective immediately prior to the opening of
business on the day following the date fixed for the determination of
stockholders entitled to receive such distribution. If after any such date fixed
for determination, any such distribution is not in fact made, the Conversion
Rate shall be immediately readjusted, effective as of the date of the Board of
Directors determines not to make such distribution, to the Conversion Rate that
would have been in effect if such determination date had not been fixed.

     (5)    In case the Company shall, by dividend or otherwise, distribute cash
(excluding cash that is distributed upon a merger or consolidation to which
Section 12.11 applies) to all holders of its Common Stock, the Conversion Rate
shall be adjusted so that the same shall equal the rate determined by dividing
the Conversion Rate in effect immediately prior to the close of business on the
date fixed for the determination of stockholders entitled to receive such
distribution by a fraction (i) the numerator of which shall be equal to the
current market price per share (determined as provided in paragraph (8) of this
Section) of the Common Stock on the date fixed for such determination and (ii)
the denominator of which shall be equal to the current market price per share
(determined as provided in paragraph (8) of this Section) of the Common Stock on
such date fixed

                                      -80-
<Page>

for determination plus the amount of the cash distribution per share, such
adjustment to become effective immediately prior to the opening of business on
the day following the date fixed for the determination of stockholders entitled
to receive such distribution. If after any such date fixed for determination,
any such distribution is not in fact made, the Conversion Rate shall be
immediately readjusted, effective as of the date of the Board of Directors
determines not to make such distribution, to the Conversion Rate that would have
been in effect if such determination date had not been fixed.

     (6)    In case the Company or any Subsidiary shall purchase shares of
Common Stock pursuant to a tender or exchange offer for all or any portion of
the Common Stock (the shares accepted by the Company or such Subsidiary in such
offer being referred to as the "Purchased Shares") and the per share amount of
cash and fair market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a Board Resolution) of any
other consideration included in the payment for a Purchased Share exceeds the
Closing Price Per Share on the Trading Day next succeeding the date (the
"Expiration Date") of the last time tenders or surrenders for exchange could
have been made pursuant to such tender or exchange offer (as it may be amended),
the Conversion Rate shall be adjusted so that the same shall equal the rate
determined by dividing the Conversion Rate immediately prior to close of
business on the Trading Day next succeeding the Expiration Date by a fraction
(i) the numerator of which shall be equal to (A) the product of (I) the current
market price per share of the Common Stock (determined as provided in paragraph
(8) of this Section) on the Expiration Date multiplied by (II) the total number
of shares of Common Stock outstanding on the Expiration Date (including the
Purchased Shares and any other shares tendered or surrendered for exchange) less
(B) the aggregate amount of cash and fair market value of other consideration to
be paid for all Purchased Shares, and (ii) the denominator of which shall be
equal to the product of (A) the current market price per share of the Common
Stock (determined as provided in paragraph (8) of this Section) on the
Expiration Date multiplied by (B) the total number of shares of Common Stock
outstanding on the Expiration Date (including the Purchased Shares and any other
shares tendered or surrendered for exchange) less the total number of Purchased
Shares, such adjustment to become effective immediately prior to the opening of
business on the day following the Trading Day next succeeding the Expiration
Date.

     (7)    The reclassification of Common Stock into securities other than
Common Stock (other than any reclassification upon a consolidation or merger to
which Section 12.11 applies) shall be deemed to involve (a) a distribution of
such securities other than Common Stock to all holders of Common Stock (and the
effective date of such reclassification shall be deemed to be "the date fixed
for the determination of stockholders entitled to receive such distribution" and
"the date fixed for such determination" within the meaning of paragraph (4) of
this Section), and (b) a subdivision or combination, as the case may be, of the
number of shares of Common Stock outstanding immediately prior to such
reclassification into the number of shares of Common Stock outstanding
immediately thereafter (and the effective date of such reclassification shall be
deemed to be "the day upon which such subdivision becomes effective" or "the day
upon which such combination becomes effective", as the case may be, and "the day
upon which such subdivision or combination becomes effective" within the meaning
of paragraph (3) of this Section).

                                      -81-
<Page>

     (8)    For the purpose of any computation under paragraphs (2), (4), or (6)
of this Section, the current market price per share of Common Stock on any date
shall be calculated by the Company and be the average of the daily Closing
Prices Per Share for the five consecutive Trading Days selected by the Company
commencing not more than 10 Trading Days before, and ending not later than the
earlier of the day in question and the day before the "ex" date with respect to
the issuance or distribution requiring such computation. For the purpose of any
computation under paragraph (5) of this Section, the current market price per
share of Common Stock on any date shall be calculated by the Company and be the
average of the daily Closing Prices Per Share for the first ten Trading Days
from and including the first "ex" date on which the Common Stock trades regular
way in the applicable securities market or on the applicable securities
exchange. For purposes of this paragraph, the term "ex' date", when used with
respect to any issuance or distribution, means the first date on which the
Common Stock trades regular way in the applicable securities market or on the
applicable securities exchange without the right to receive such issuance or
distribution.

     (9)    No adjustment in the Conversion Rate shall be required unless such
adjustment (plus any adjustments not previously made by reason of this paragraph
(9)) would require an increase or decrease of at least one percent in such rate;
PROVIDED, HOWEVER, that any adjustments which by reason of this paragraph (9)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Article shall be made to
the nearest cent or to the nearest one-hundredth of a share, as the case may be.

     (10)   The Company may make such increases in the Conversion Rate, for the
remaining term of the Securities or any shorter term, in addition to those
required by paragraphs (1), (2), (3), (4), (5) and (6) of this Section, as it
considers to be advisable in order to avoid or diminish any income tax to any
holders of shares of Common Stock resulting from any dividend or distribution of
stock or issuance of rights or warrants to purchase or subscribe for stock or
from any event treated as such for income tax purposes. The Company shall have
the power to resolve any ambiguity or correct any error in this paragraph (10)
and its actions in so doing shall, absent manifest error, be final and
conclusive.

     (11)   Notwithstanding the foregoing provisions of this Section, no
adjustment of the Conversion Rate shall be required to be made (a) upon the
issuance of shares of Common Stock pursuant to any present or future plan for
the reinvestment of dividends or (b) because of a tender or exchange offer of
the character described in Rule 13e-4(h)(5) under the Exchange Act or any
successor rule thereto.

     (12)   To the extent permitted by applicable law, the Company from time to
time may increase the Conversion Rate by any amount for any period of time if
the period is at least twenty days, the increase is irrevocable during such
period, and the Board of Directors shall have made a determination that such
increase would be in the best interests of the Company, which determination
shall be conclusive; PROVIDED, HOWEVER, that no such increase shall be taken
into account for purposes of determining whether the Closing Price Per Share of
the Common Stock equals or exceeds 105% of the Conversion Price in connection
with an event which would otherwise be a Change of Control pursuant to Section
14.5. Whenever the Conversion Rate is increased pursuant to the preceding
sentence, the Company shall give notice of the increase to the Holders in the
manner

                                      -82-
<Page>

provided in Section 1.6 at least 15 days prior to the date the increased
Conversion Rate takes effect, and such notice shall state the increased
Conversion Rate and the period during which it will be in effect.

Section 12.5   NOTICE OF ADJUSTMENTS OF CONVERSION RATE.

     Whenever the Conversion Rate is adjusted as herein provided:

     (1)    the Company shall compute the adjusted Conversion Rate in accordance
with Section 12.4 and shall prepare a certificate signed by the Chief Financial
Officer of the Company setting forth the adjusted Conversion Rate and showing in
reasonable detail the facts upon which such adjustment is based, and such
certificate shall promptly be filed with the Trustee and with each Conversion
Agent; and

     (2)    upon each such adjustment, a notice stating that the Conversion Rate
has been adjusted and setting forth the adjusted Conversion Rate shall be
required, and as soon as practicable after it is required, such notice shall be
provided by the Company to all Holders in accordance with Section 1.6.

     Neither the Trustee nor any Conversion Agent shall be under any duty or
responsibility with respect to any such certificate or the information and
calculations contained therein, except to exhibit the same to any Holder of
Securities desiring inspection thereof at its office during normal business
hours.

Section 12.6   NOTICE OF CERTAIN CORPORATE ACTION.

     In case:

     (1)    the Company shall declare a dividend (or any other distribution) on
its Common Stock; or

     (2)    the Company shall authorize the granting to all or substantially all
of the holders of its Common Stock of rights, options or warrants to subscribe
for or purchase any shares of capital stock of any class or of any other rights;
or

     (3)    of any reclassification of the Common Stock, or of any
consolidation, merger or share exchange to which the Company is a party and for
which approval of any stockholders of the Company is required, or of the
conveyance, sale, transfer or lease of all or substantially all of the assets of
the Company; or

     (4)    of the voluntary or involuntary dissolution, liquidation or winding
up of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to Section 10.2, and shall
cause to be provided to all Holders in accordance with Section 1.6, at least 20
days (or 10 days in any case specified in clause (1) or (2)

                                      -83-
<Page>

above) prior to the applicable record or effective date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution, rights, options or warrants, or, if a record is not
to be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution, rights, options or warrants are to be
determined or (y) the date on which such reclassification, consolidation,
merger, conveyance, transfer, sale, lease, dissolution, liquidation or winding
up is expected to become effective, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, conveyance, transfer, sale, lease,
dissolution, liquidation or winding up. Neither the failure to give such notice
or the notice referred to in the following paragraph nor any defect therein
shall affect the legality or validity of the proceedings described in clauses
(1) through (4) of this Section. If at the time the Trustee shall not be the
Conversion Agent, a copy of such notice shall also forthwith be filed by the
Company with the Trustee.

     The Company shall cause to be filed at the Corporate Trust Office and each
office or agency maintained for the purpose of conversion of Securities pursuant
to Section 10.2, and shall cause to be provided to all Holders in accordance
with Section 1.6, notice of any tender offer by the Company or any Subsidiary
for all or any portion of the Common Stock at or about the time that such notice
of tender offer is provided to the public generally.

Section 12.7   COMPANY TO RESERVE COMMON STOCK.

     The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock then issuable upon the conversion of all Outstanding Securities.

Section 12.8   TAXES ON CONVERSIONS.

     Except as provided in the next sentence, the Company will pay any and all
taxes and duties that may be payable in respect of the issue or delivery of
shares of Common Stock on conversion of Securities pursuant hereto. The Company
shall not, however, be required to pay any tax or duty that may be payable in
respect of (i) income of the Holder, or (ii) any transfer involved in the issue
and delivery of shares of Common Stock in a name other than that of the Holder
of the Security or Securities to be converted, and no such issue or delivery
shall be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax or duty, or has established to the
satisfaction of the Company that such tax or duty has been paid.

Section 12.9   COVENANT AS TO COMMON STOCK.

     The Company agrees that all shares of Common Stock that may be delivered
upon conversion of Securities, upon such delivery, will have been duly
authorized and validly issued and will be fully paid and nonassessable and,
except as provided in Section 12.8, the Company will pay all taxes, liens and
charges with respect to the issue thereof.

                                      -84-
<Page>

Section 12.10  CANCELLATION OF CONVERTED SECURITIES.

     All Securities delivered for conversion shall be delivered to the Trustee
or its agent to be canceled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 3.9.

Section 12.11  PROVISION IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS.

     In case of any consolidation or merger of the Company with or into any
other Person, any merger of another Person with or into the Company (other than
a merger that does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company) or any
conveyance, sale, transfer or lease of all or substantially all of the assets of
the Company (other than a sale of all or substantially all of the assets of the
Company that does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company), the Person
formed by such consolidation or resulting from such merger or which acquires
such assets, as the case may be, shall execute and deliver to the Trustee a
supplemental indenture providing that the Holder of each Security then
Outstanding shall have the right thereafter, during the period such Security
shall be convertible as specified in Section 12.1, to convert such Security only
into the kind and amount of securities, cash and other property receivable upon
such consolidation, merger, conveyance, sale, transfer or lease by a holder of
the number of shares of Common Stock of the Company into which such Security
might have been converted immediately prior to such consolidation, merger,
conveyance, sale, transfer or lease, assuming such holder of Common Stock of the
Company (i) is not (A) a Person with which the Company consolidated or merged
with or into or which merged into or with the Company or to which such
conveyance, sale, transfer or lease was made, as the case may be (a "Constituent
Person"), or (B) an Affiliate of a Constituent Person and (ii) failed to
exercise his rights of election, if any, as to the kind or amount of securities,
cash and other property receivable upon such consolidation, merger, conveyance,
sale, transfer or lease (PROVIDED that if the kind or amount of securities, cash
and other property receivable upon such consolidation, merger, conveyance, sale,
transfer, or lease is not the same for each share of Common Stock of the Company
held immediately prior to such consolidation, merger, conveyance, sale, transfer
or lease by others than a Constituent Person or an Affiliate thereof and in
respect of which such rights of election shall not have been exercised
("Non-electing Share"), then for the purpose of this Section the kind and amount
of securities, cash and other property receivable upon such consolidation,
merger, conveyance, sale, transfer or lease by the holders of each Non-electing
Share shall be deemed to be the kind and amount so receivable per share by a
plurality of the Non-electing Shares). Such supplemental indenture shall provide
for adjustments that, for events subsequent to the effective date of such
supplemental indenture, shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Article. The above provisions of this
Section shall similarly apply to successive consolidations, mergers,
conveyances, sales, transfers or leases. Notice of the execution of such a
supplemental indenture shall be given by the Company to the Holder of each
Security as provided in Section 1.6 promptly upon such execution.

     Neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any
such supplemental indenture relating either to the

                                      -85-
<Page>

kind or amount of shares of stock or other securities or property or cash
receivable by Holders of Securities upon the conversion of their Securities
after any such consolidation, merger, conveyance, transfer, sale or lease or to
any such adjustment, but may accept as conclusive evidence of the correctness of
any such provisions, and shall be protected in relying upon, an Opinion of
Counsel with respect thereto, which the Company shall cause to be furnished to
the Trustee upon request.

Section 12.12  RIGHTS ISSUED IN RESPECT OF COMMON STOCK.

     Rights or warrants distributed by the Company to all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights or warrants, until the occurrence of a specified event or events
("Trigger Event"):

             (i)  are deemed to be transferred with such shares of Common Stock,

            (ii)  are not exercisable, and

           (iii)  are also issued in respect of future issuances of Common Stock

shall not be deemed distributed for purposes of Section 12.4(2) until the
occurrence of the earliest Trigger Event. In addition, in the event of any
distribution of rights or warrants, or any Trigger Event with respect thereto,
that shall have resulted in an adjustment to the Conversion Rate under Section
12.4(2), (1) in the case of any such rights or warrants that shall all have been
redeemed or repurchased without exercise by any holders thereof, the Conversion
Rate shall be readjusted upon such final redemption or repurchase to give effect
to such distribution or Trigger Event, as the case may be, as though it were a
cash distribution, equal to the per share redemption or repurchase price
received by a holder of Common Stock with respect to such rights or warrants
(assuming such holder had retained such rights or warrants), made to all holders
of Common Stock as of the date of such redemption or repurchase, and (2) in the
case of any such rights or warrants all of which shall have expired without
exercise by any holder thereof, the Conversion Price shall be readjusted as if
such issuance had not occurred.

Section 12.13  RESPONSIBILITY OF TRUSTEE FOR CONVERSION PROVISIONS.

     The Trustee, subject to the provisions of Section 6.1, and any Conversion
Agent shall not at any time be under any duty or responsibility to any Holder of
Securities to determine whether any facts exist which may require any adjustment
of the Conversion Rate, or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed, herein or in any
supplemental indenture provided to be employed, in making the same, or whether a
supplemental indenture need be entered into. Neither the Trustee, subject to the
provisions of Section 6.1, nor any Conversion Agent shall be accountable with
respect to the validity or value (or the kind or amount) of any Common Stock, or
of any other securities or property or cash, which may at any time be issued or
delivered upon the conversion of any Security; and it or they do not make any
representation with respect thereto. Neither the Trustee, subject to the
provisions of Section 6.1, nor any Conversion Agent shall be responsible for any
failure of the Company to make or calculate any cash payment or to issue,
transfer or deliver any shares of Common Stock or share certificates or

                                      -86-
<Page>

other securities or property or cash upon the surrender of any Security for the
purpose of conversion; and the Trustee, subject to the provisions of Section
6.1, and any Conversion Agent shall not be responsible for any failure of the
Company to comply with any of the covenants of the Company contained in this
Article.

                                  ARTICLE XIII

Section 13.1   COMPANY'S OPTION TO EFFECT DEFEASANCE.

     The Company may elect, at its option at any time, to have Section 13.2
applied to any Securities upon compliance with the conditions set forth below in
this Article. Any such election shall be evidenced by a Board Resolution.

Section 13.2   DEFEASANCE AND DISCHARGE.

     Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities, the Company shall be deemed to have been discharged
from its obligations with respect to such Securities as provided in this Section
on and after the date the conditions set forth in Section 13.3 are satisfied
(hereinafter called "Defeasance"). For this purpose, such Defeasance means that
the Company shall be deemed to have paid and discharged the entire indebtedness
represented by such Securities and to have satisfied all its other obligations
under such Securities and this Indenture insofar as such Securities are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), subject to the following which shall
survive until otherwise terminated or discharged hereunder: (1) the rights of
Holders of such Securities to receive, solely from the trust fund described in
Section 13.3 and as more fully set forth in such Section, payments in respect of
the principal of and interest on such Securities when payments are due, (2) the
Company's obligations with respect to such Securities under Section 3.4, Section
3.5, Section 3.6, Section 10.2 and Section 10.3, (3) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (4) this Article. Subject to
compliance with this Article, the Company may exercise its option (if any) to
have this Section applied to any Securities.

Section 13.3   CONDITIONS TO DEFEASANCE.

     The following shall be the conditions to the application of Section 13.2 to
any Securities:

     (1)    The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee which satisfies the requirements
contemplated by Section 6.8 and agrees to comply with the provisions of this
Article applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefits of the Holders of such Securities, (A) money in an amount, or
(B) U.S. Government Obligations which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or

                                      -87-
<Page>

nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or any such other qualifying trustee)
to pay and discharge, the principal of and interest (including any Liquidated
Damages) on such Securities on the respective Stated Maturities, in accordance
with the terms of this Indenture and such Securities. As used herein, "U.S.
Government Obligation" means (x) any security which is (i) a direct obligation
of the United States of America for the payment of which the full faith and
credit of the United States of America is pledged or (ii) an obligation of a
Person controlled or supervised by and acting as an agency or instrumentality of
the United States of America the payment of which is unconditionally guaranteed
as a full faith and credit obligation by the United States of America, which, in
either case (i) or (ii), is not callable or redeemable at the option of the
issuer thereof, and (y) any depositary receipt issued by a bank (as defined in
Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S.
Government Obligation which is specified in Clause (x) above and held by such
bank for the account of the holder of such depositary receipt, or with respect
to any specific payment of principal of or interest on any U.S. Government
Obligation which is so specified and held, provided that (except as required by
law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depositary receipt from any amount received by the
custodian in respect of the U.S. Government Obligation or the specific payment
of principal or interest evidenced by such depositary receipt.

     (2)    In the event of an election to have Section 13.2 apply to any
Securities, the Company shall have delivered to the Trustee an Opinion of
Counsel stating that (A) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (B) since the date of
this instrument, there has been a change in the applicable Federal income tax
law, in either case (A) or (B) to the effect that, and based thereon such
opinion shall confirm that, the Holders of such Securities will not recognize
gain or loss for Federal income tax purposes as a result of the deposit,
Defeasance and discharge to be effected with respect to such Securities and will
be subject to Federal income tax on the same amount, in the same manner and at
the same times as would be the case if such deposit, Defeasance and discharge
were not to occur.

     (3)    The Company shall have delivered to the Trustee an Officers'
Certificate to the effect that such Securities, if then listed on any securities
exchange, will be delisted as a result of such deposit.

     (4)    No event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to such Securities or any other
Securities shall have occurred and be continuing at the time of such deposit or,
with regard to any such event specified in Section 5.1(7) and (8), at any time
on or prior to the 90th day after the date of such deposit (it being understood
that this condition shall not be deemed satisfied until after such 90th day).

     (5)    Such Defeasance shall not cause the Trustee to have a conflicting
interest within the meaning of the Trust Indenture Act (assuming all Securities
are in default within the meaning of such Act).

     (6)    Such Defeasance shall not result in a breach or violation of, or
constitute a default under, any other agreement or instrument to which the
Company is a party or by which it is bound.

                                      -88-
<Page>

     (7)    Such Defeasance shall not result in the trust arising from such
deposit constituting an investment company within the meaning of the Investment
Company Act unless such trust shall be registered under the Investment Company
Act or exempt from registration thereunder.

     (8)    The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Defeasance have been complied with.

Section 13.4   DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
               TRUST; MISCELLANEOUS PROVISIONS.

     Subject to the provisions of the last paragraph of Section 10.3, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee or other qualifying trustee (solely for purposes of this Section and
Section 13.5, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 13.3 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
and interest, but money so held in trust need not be segregated from other funds
except to the extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 13.3 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon Company Request any money
or U.S. Government Obligations held by it as provided in Section 13.3 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance with respect to such
Securities.

Section 13.5   REINSTATEMENT.

     If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 13.2 shall be revived and reinstated as though no
deposit had occurred pursuant to this Article with respect to such Securities,
until such time as the Trustee or Paying Agent is permitted to apply all money
held in trust pursuant to Section 13.4 with respect to such Securities in
accordance with this Article; provided, however, that if the Company makes any
payment of principal of or interest on any such Security following such
reinstatement of its

                                      -89-
<Page>

obligations, the Company shall be subrogated to the rights (if any) of the
Holders of such Securities to receive such payment from the money so held in
trust.

                                   ARTICLE XIV
                            REPURCHASE OF SECURITIES

Section 14.1   RIGHT TO REQUIRE REPURCHASE.

            (A)    Securities shall be repurchased by the Company pursuant to
the terms of the Securities at the option of the Holder on August 1, 2008 (the
"Repurchase Date"), at a repurchase price equal to 100% of the principal amount
of the Securities to be repurchased (any such portion being at least $1,000 or
an integral multiple of $1,000 in excess thereof and PROVIDED that no single
Security may be repurchased in part unless the portion of the principal amount
of such Security to be Outstanding after such repurchase is equal to $1,000 or
integral multiples of U.S. $1,000 in excess thereof), plus interest accrued but
unpaid to, but excluding, such Repurchase Date (the "Repurchase Price"), subject
to the provisions of Section 14.3. At the option of the Company, the Repurchase
Price may be paid in cash, or subject to the fulfillment by the Company of the
conditions set forth in Section 14.3, by delivery of shares of Common Stock
having a fair market value to the Repurchase Price (less any cash payments), or
a combination of cash and Common Stock. Whenever in this Indenture (including
Section 2.2, Section 3.1, Section 5.1(1) and Section 5.8) there is a reference,
in any context, to the principal of any Security as of any time, such reference
shall be deemed to include reference to the Repurchase Price payable in respect
of such Security to the extent that such Repurchase Price is, was or would be so
payable at such time, and express mention of the Repurchase Price in any
provision of this Indenture shall not be construed as excluding the Repurchase
Price in those provisions of this Indenture when such express mention is not
made.

Section 14.2   RIGHT TO REQUIRE REPURCHASE UPON A CHANGE IN CONTROL.

     In the event that a Change in Control (as hereinafter defined) shall occur,
then each Holder shall have the right, at the Holder's option, but subject to
the provisions of Section 14.3, to require the Company to repurchase, and upon
the exercise of such right the Company shall repurchase, all of such Holder's
Securities not theretofore called for redemption, or any portion of the
principal amount thereof that is equal to $1,000 or any integral multiple of
$1,000 in excess thereof (PROVIDED, HOWEVER, that no single Security may be
repurchased in part unless the portion of the principal amount of such Security
to be Outstanding after such repurchase is equal to $1,000 or integral multiples
of U.S. $1,000 in excess thereof), on the date (the "Change in Control
Repurchase Date") that is 35 Business Days after the date of the Company Notice
(as defined in Section 14.4), at a repurchase price equal to 100% of the
principal amount of the Securities to be repurchased plus interest accrued but
unpaid to, but excluding, the Change in Control Repurchase Date (the "Change in
Control Repurchase Price"); PROVIDED, HOWEVER, that installments of interest on
Securities whose Stated Maturity is on or prior to the Change in Control
Repurchase Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such on the relevant Record Date
according to their terms and the provisions of Section 3.7. Such right to
require the

                                      -90-
<Page>

repurchase of the Securities shall not continue after a discharge of the Company
from its obligations with respect to the Securities in accordance with Article
IV, unless a Change in Control shall have occurred prior to such discharge. At
the option of the Company, the Change in Control Repurchase Price may be paid in
cash or, subject to the fulfillment by the Company of the conditions set forth
in Section 14.3, by delivery of shares of Common Stock having a fair market
value equal to the Change in Control Repurchase Price (less any cash payments),
or a combination of cash and Common Stock. Whenever in this Indenture (including
Section 2.2, Section 3.1, Section 5.1(1) and Section 5.8) there is a reference,
in any context, to the principal of any Security as of any time, such reference
shall be deemed to include reference to the Change in Control Repurchase Price
payable in respect of such Security to the extent that such Change in Control
Repurchase Price is, was or would be so payable at such time, and express
mention of the Change in Control Repurchase Price in any provision of this
Indenture shall not be construed as excluding the Change in Control Repurchase
Price in those provisions of this Indenture when such express mention is not
made.

Section 14.3   CONDITIONS TO THE COMPANY'S ELECTION TO PAY THE REPURCHASE PRICE
               OR THE CHANGE IN CONTROL REPURCHASE PRICE IN COMMON STOCK.

     The Company may elect to pay the Repurchase Price or the Change in Control

Control Repurchase Price, as the case may be. For purposes of Section 14.1,
Section 14.2 and this Section, the fair market value of shares of Common Stock
shall be determined by the Company and shall be equal to 95% of the average of
the Closing Prices Per Share of the Common Stock for the five consecutive
Trading Days immediately preceding and including the third Trading Day prior to
the Repurchase Date or Change in Control Repurchase Date, as the case may be;

     (2)    The Repurchase Price, or Change in Control Repurchase Price, as the
case may be, shall be paid only in cash in the event that any shares of Common
Stock to be issued upon repurchase of Securities hereunder (i) require
registration under any federal securities law before such shares may be freely
transferable without being subject to any transfer restrictions under the
Securities Act upon repurchase and if such registration is not completed or does
not become effective prior to the Repurchase Date or Change in Control
Repurchase Date, as the case may be, and/or (ii) require registration with or
approval of any governmental authority under any state law or any other federal
law before such shares may be validly issued or delivered upon repurchase and if

Date, as the case may be;

                                      -91-
<Page>

     (3)    Payment of the Repurchase Price or the Change in Control Repurchase
Price, as the case may be, may not be made in Common Stock unless such stock is,
or shall have been, listed or approved for quotation on the Nasdaq National
Market or listed or approved for quotation on a national securities exchange or
quotation system, in either case, prior to the Repurchase Date or the Change in
Control Repurchase Date, as the case may be; and

     (4)    All shares of Common Stock that may be issued upon repurchase of
Securities will be issued out of the Company's authorized but unissued Common
Stock (or, in the event of a merger, consolidation or other similar transaction
involving the Company that is otherwise permitted under the terms of this
Indenture in which the Company is not the surviving entity, out of the
authorized but unissued Common Stock of the surviving entity or its direct or
indirect parent entity) and, will upon issue, be duly and validly issued and
fully paid and nonassessable and free of any preemptive or similar rights.

Section 14.4   NOTICES; METHOD OF EXERCISING REPURCHASE RIGHT, ETC.

     (1)    Unless the Company shall have theretofore called for redemption all
of the Outstanding Securities, the Company shall give to all Holders of
Securities, in the manner provided in Section 1.6, notice (the "Company

on or before the 20th Business Day prior to the Repurchase Date or on or before
the 30th day after the occurrence of a Change in Control, as the case may be,

Trustee shall give the Company Notice to the Holders.

     Each Company Notice shall state:

applicable ratio of cash and Common Stock),

            (D)    if the notice relates to the occurrence of a Change in
Control, the events causing the Change in Control and the date of the Change in
Control,

Repurchase Price, as the case may be, and accrued

                                      -92-
<Page>

but unpaid interest (including Liquidated Damages), if any, to the Repurchase
Date or the Change in Control Repurchase Date, as the case may be,

            (F)    that on the Repurchase Date or the Change in Control
Repurchase Date, as the case may be, the Repurchase Price or the Change in
Control Repurchase Price, as the case may be, and accrued but unpaid interest
(including Liquidated Damages), if any, to the Repurchase Date or the Change in
Control Repurchase Date, as the case may be, will become due and payable upon
each such Security designated by the Holder to be repurchased, and that interest
thereon shall cease to accrue on and after said date,

            (G)    the Conversion Rate then in effect, the date on which the
right to convert the principal amount of the Securities to be repurchased will
terminate and the place or places where such Securities may be surrendered for
conversion,

            (H)    the place or places that the Security certificate with the

place or places that the Surrender Certificate required by Section 14.4 shall be
delivered, and

            (I)    the name and address of the Paying Agent and Conversion
Agent.

     No failure of the Company to give the foregoing notices or defect therein
shall limit any Holder's right to exercise a repurchase right or affect the
validity of the proceedings for the repurchase of Securities.

     If any of the foregoing provisions or other provisions of this Article are
inconsistent with applicable law, such law shall govern.

     (2)    To exercise a repurchase right pursuant to Section 14.1 or Section
14.2, a Holder shall deliver to the Trustee (i) written notice (a "Repurchase
Notice") of the Holder's exercise of such right, which notice shall set forth
the name of the Holder, the principal amount of the Securities to be repurchased
(and, if any Security is to repurchased in part, the serial number thereof, the
portion of the principal amount thereof to be repurchased (which portion must be
in principal amounts of $1,000 or a whole multiple of $1,000) and the name of
the Person in which the portion thereof to remain Outstanding after such
repurchase is to be registered) and a statement that an election to exercise the
repurchase right pursuant to the terms and conditions specified in the
Securities and the Indenture is being made thereby, and, in the event that any
portion of the Repurchase Price or the Change in Control Repurchase Price, as
the case may be, shall be paid in shares of Common Stock, the name or names
(with addresses) in which the certificate or certificates for shares of Common
Stock shall be issued, and (ii) book-entry transfer or delivery of such Security
to the Paying Agent at any time after delivery of the Repurchase Notice
(together with all necessary endorsements) at the offices of the Paying Agent,
such delivery being a condition to receipt by the Holder of the Repurchase Price
therefor or the Change in Control Repurchase Price therefor, as the case may be,
PROVIDED, HOWEVER, that such Repurchase Price or Change in Control Repurchase
Price, as the case may be, shall be so paid pursuant to this Section only if the
Security so delivered to the Paying Agent shall conform in all respects to the
description thereof in the related Repurchase Notice. In the

                                      -93-
<Page>

case of a repurchase right pursuant to Section 14.1, such delivery shall be at
any time from the opening of business on the date that is 20 Business Days prior
to the Repurchase Date until the close of business on the fifth Business Day
prior to the Repurchase Date and in the case of a repurchase right pursuant to
Section 14.2, such delivery shall be on or before the 35th day after the date of
the Company Notice.

     A repurchase notice given by a Holder in accordance with this Section may
be withdrawn by means of a written notice of withdrawal delivered to the office
of the Paying Agent at any time prior to the close of business on the day that
is two Business Days before the Repurchase Date or Change in Control Repurchase
Date, as the case may be, specifying:

            (A)    the certificate number, if any, of the Security in respect of
which such notice of withdrawal is being submitted, or the appropriate
Depositary procedures if Certificated Securities have not been issued,

            (B)    the principal amount of the Security with respect to which
such notice of withdrawal is being submitted, and

            (C)    the principal amount, if any, of such Security which remains
subject to the original Repurchase Notice and which has been or will be
delivered for purchase by the Company.

     The Company may, in its sole and complete discretion, accept a written
notice of withdrawal on or after the close of business on the day that is two
Business Days prior to the Repurchase Date or a Change in Control Repurchase
Date, as the case may be. The decision of the Company to accept or reject such a
withdrawal notice shall be conclusive and binding on the Holder proposing to
make the withdrawal.

     (3)    There shall be no purchase of any Securities pursuant to this
Article if an Event of Default has occurred and is continuing (other than a
default that is cured by the payment of the Repurchase Price or Change in
Control Repurchase Price, as the case be). The Paying Agent shall promptly
return to the respective Holders thereof any Notes (i) with respect to which a
Repurchase Notice or Change in Control Repurchase Notice, as the case may be,
has been withdrawn in compliance with this Indenture or (ii) held by it during
the continuance of an Event of Default (other than a default that is cured by
the payment of the Repurchase Price or Change in Control Repurchase Price, as
the case may be ) in which case, upon such return, the Repurchase Notice or
Change in Control Repurchase Notice with respect thereto shall be deemed to have
been withdrawn.

     (4)    In the event a repurchase right shall be exercised in accordance
with the terms hereof, the Company shall pay or cause to be paid to the Trustee
the Repurchase Price or the Change in Control Repurchase Price, as the case may
be, in cash or shares of Common Stock, as provided in Section 14.3, for payment
to the Holder on the Repurchase Date or the Change in Control Repurchase Date,
as the case may be, or, if shares of Common Stock are to be paid, on the date
that is 35 days after the date of the Company's Notice, together with accrued
and unpaid interest to the Repurchase Date or the Change in Control Repurchase
Date, as the case may be, payable with respect to the Securities as to which the
repurchase right has been exercised; PROVIDED, HOWEVER, that installments of
interest that mature on or prior to the Repurchase Date or the Change in Control

                                      -94-
<Page>

Repurchase Date, as the case may be, shall be payable in cash to the Holders of
such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Regular Record Date.

     (5)    If any Security (or portion thereof) surrendered for repurchase
shall not be so paid on the Repurchase Date or the Change in Control Repurchase
Date, as the case may be, the principal amount of such Security (or portion
thereof, as the case may be) shall, until paid, bear interest to the extent
permitted by applicable law from the Repurchase Date or the Change in Control
Repurchase Date, as the case may be, at the rate then in effect per annum, and
each Security shall remain convertible into Common Stock until the principal of
such Security (or portion thereof, as the case may be) shall have been paid or
duly provided for.

     (6)    Any Security that is to be repurchased only in part shall be
surrendered to the Trustee (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and make available for delivery to the Holder of such
Security without service charge, a new Security or Securities, containing
identical terms and conditions, each in an authorized denomination in aggregate
principal amount equal to and in exchange for the unrepurchased portion of the
principal of the Security so surrendered.

     (7)    Any issuance of shares of Common Stock in respect of the Repurchase
Price or the Change in Control Repurchase Price, as the case may be, shall be
deemed to have been effected immediately prior to the close of business on the
Repurchase Date or the Change in Control Repurchase Date, as the case may be,
and the Person or Persons in whose name or names any certificate or certificates
for shares of Common Stock shall be issuable upon such repurchase shall be
deemed to have become on the Repurchase Date or the Change in Control Repurchase
Date, as the case may be, the holder or holders of record of the shares
represented thereby; PROVIDED, HOWEVER, that any surrender for repurchase on a
date when the stock transfer books of the Company shall be closed shall
constitute the Person or Persons in whose name or names the certificate or
certificates for such shares are to be issued as the record holder or holders
thereof for all purposes at the opening of business on the next succeeding day
on which such stock transfer books are open. No payment or adjustment shall be
made for dividends or distributions on any Common Stock issued upon repurchase
of any Security declared prior to the Repurchase Date or the Change in Control
Repurchase Date, as the case may be.

     (8)    No fractions of shares shall be issued upon repurchase of
Securities. If more than one Security shall be repurchased from the same Holder
and the Repurchase Price or the Change in Control Repurchase Price, as the case
may be, shall be payable in shares of Common Stock, then the number of full
shares that shall be issuable upon such repurchase shall be computed on the
basis of the aggregate principal amount of the Securities so repurchased.
Instead of any fractional share of Common Stock that would otherwise be issuable
on the repurchase of any Security or Securities, the Company will deliver to the
applicable Holder its check for the current market value of such fractional
share. The current market value of a fraction of a share is determined by
multiplying the current market price of a full share by the fraction, and
rounding the result to the nearest cent. For

                                      -95-
<Page>

purposes of this Section, the current market price of a share of Common Stock is
the Closing Price Per Share of the Common Stock on the Trading Day immediately
preceding the Repurchase Date or the Change in Control Repurchase Date, as the
case may be.

     (9)    Any issuance and delivery of certificates for shares of Common Stock
on repurchase of Securities shall be made without charge to the Holder of
Securities being repurchased for such certificates or for any tax or duty in
respect of the issuance or delivery of such certificates or the securities
represented thereby; PROVIDED, HOWEVER, that the Company shall not be required
to pay any tax or duty that may be payable in respect of (i) income of the
Holder or (ii) any transfer involved in the issuance or delivery of certificates
for shares of Common Stock in a name other than that of the Holder of the
Securities being repurchased, and no such issuance or delivery shall be made
unless and until the Person requesting such issuance or delivery has paid to the
Company the amount of any such tax or duty or has established, to the
satisfaction of the Company, that such tax or duty has been paid.

     (10)   If shares of Common Stock to be delivered upon repurchase of a
Restricted Security are to be registered in a name other than that of the
beneficial owner of such Security, then such Holder must deliver to the Trustee
a Surrender Certificate, dated the date of surrender of such Restricted Security
and signed by such beneficial owner, as to compliance with the restrictions on
transfer applicable to such Restricted Security. Neither the Trustee nor any
Registrar or Transfer Agent or other agents shall be required to register in a
name other than that of the beneficial owner shares of Common Stock issued upon
repurchase of any such Restricted Security not so accompanied by a properly
completed Surrender Certificate.

     (11)   All Securities delivered for repurchase shall be delivered to the
Trustee to be canceled at the direction of the Trustee, which shall dispose of
the same as provided in Section 3.9.
