         be deemed to refer to the same as from time to time amended and in
         effect and to any successor statute, law, rule or regulation; and

                  (h) references to any contract, agreement or instrument shall
         mean the same as amended, modified, supplemented or amended and
         restated from time to time, in each case, in accordance with any
         applicable restrictions contained in this Indenture.

                                    ARTICLE 2

                                    THE NOTES

         Section 2.01 FORM AND DATING. The Notes, the Trustee's certificate of
authentication and the conversion notices shall be substantially in the form of
Exhibit A hereto. The Notes may have notations, legends or endorsements required
by law, stock exchange rule or usage. Each Note shall be dated the date of its
authentication. The Notes shall be in denominations of U.S. $1,000 and integral
multiples thereof.

         The terms and provisions contained in the Notes shall constitute, and
are hereby expressly made, a part of this Indenture and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions

                                       12

and to be bound thereby. However, to the extent any provision of any Note
conflicts with the express provisions of this Indenture, the provisions of this
Indenture shall govern and be controlling.

         Upon their original issuance, Notes issued as contemplated by the
Underwriting Agreement shall be issued in the form of one or more Global Notes
in definitive, fully registered form without interest coupons. Such Global Note
shall be registered in the name of DTC, as Depositary, or its nominee and
deposited with the Trustee, as custodian for DTC, for credit by DTC to the
respective accounts of beneficial owners of the Notes represented thereby (or
such other accounts as they may direct).

         Section 2.02 EXECUTION AND AUTHENTICATION. Two Officers shall sign the
Notes for the Company by manual or facsimile signature.

         If an Officer whose signature is on a Note no longer holds that office
at the time a Note is authenticated, the Note shall nevertheless be valid.

         A Note shall not be valid until authenticated by the manual signature
(which may be by facsimile) of the Trustee. The signature shall be conclusive
evidence that the Note has been authenticated under this Indenture.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Notes executed by the Company to the
Trustee for authentication; and the Trustee shall authenticate and deliver such
Notes upon a written order of the Company signed by an Officer of the Company
(an "Authentication Order"). Such Authentication Order shall specify the amount
of Notes to be authenticated and the date on which the Notes are to be
authenticated and whether the Notes are to be issued as one or more Global Notes
and such other information as the Company may include or the Trustee may
reasonably request. The aggregate principal amount of Notes that may be
outstanding under this Indenture at any time may not exceed $250,000,000 (or up
to $287,500,000 to the extent the Underwriters exercise their over-allotment
option pursuant to the Underwriting Agreement), except as provided in Section
2.08.

         The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

         Section 2.03 REGISTRAR; CONVERSION AGENT; AND PAYING AGENT. The Company
shall maintain an office or agency where Notes may be presented for registration
of transfer or for exchange or conversion ("Registrar" and with respect to
conversion, "Conversion Agent") and an office or agency where Notes may be
presented for payment

                                       13
<Page>

("Paying Agent"). The Registrar shall keep a register of the Notes and of their
transfer, exchange and conversion (the register maintained in such office, the
"Note Register"). The Company may appoint one or more co-registrars or
conversion agents and one or more additional paying agents. The term "Registrar"
includes any co-registrar, the term "Conversion Agent" includes any
co-conversion agent and the term "Paying Agent" includes any additional paying
agent. The Company may change any Paying Agent, Registrar or Conversion Agent
without notice to any Holder. The Company shall promptly notify the Trustee in
writing of the name and address of any Agent not a party to this Indenture. If
the Company fails to appoint or maintain another entity as Registrar, Paying
Agent or Conversion Agent, the Trustee shall act as such. The Company or any of
its Subsidiaries may act as Paying Agent, Registrar or Conversion Agent.

         The Company initially appoints DTC to act as Depositary with respect to
the Global Notes.

         The Company initially appoints the Trustee to act as the Registrar,
Paying Agent and Conversion Agent and to act as custodian with respect to the
Global Notes.

         Section 2.04 PAYING AGENT TO HOLD MONEY IN TRUST. The Company shall
require each Paying Agent other than the Trustee to agree in writing that the
Paying Agent shall hold in trust for the benefit of Holders or the Trustee all
money held by the Paying Agent for the payment of principal, premium, if any
(including the Make-Whole Payment, if any), or interest on the Notes, and shall
notify the Trustee of any default by the Company in making any such payment.
While any such default continues, the Trustee may require a Paying Agent to pay
all money held by it to the Trustee. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee. Upon payment over to
the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall
have no further liability for the money. If the Company or a Subsidiary acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the
benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy
or reorganization proceedings relating to the Company, the Trustee shall serve
as Paying Agent for the Notes.

         Section 2.05 HOLDER LISTS. The Trustee shall preserve in as current a
form as is reasonably practicable the most recent list available to it of the
names and addresses of all Holders and shall otherwise comply with TIA Section
312(a). If the Trustee is not the Registrar, the Company shall furnish to the
Trustee at least seven Business Days before each interest payment date and at
such other times as the Trustee may request in writing, a list in such form and
as of such date as the Trustee may reasonably require of the names and addresses
of the Holders and the Company shall otherwise comply with TIA Section 312(a).

         Section 2.06 GLOBAL NOTES; NON-GLOBAL NOTES; BOOK-ENTRY PROVISIONS.

                  (1) GLOBAL NOTES.

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

                           (ii) Except for exchanges of Global Notes for
                  definitive, Non-global Notes at the sole discretion of the
                  Company, no Global Note may be exchanged in whole or in part
                  for Notes registered, and no transfer of a Global Note in
                  whole or in part may be registered, in the name of any Person
                  other than the Depositary for such Global Note 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 Note 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
                  Note. In case of an event under clause (A) of the preceding
                  sentence, if a successor Depositary for such Global Note 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 Notes, will authenticate and deliver, Notes in any
                  authorized denominations in an aggregate principal amount
                  equal to the principal amount of such Global Note in exchange
                  for such Global Note.

                           (iii) If any Global Note is to be exchanged for other
                  Notes or canceled in whole, it shall be surrendered by or on
                  behalf of the Depositary or its nominee to the Registrar, for
                  exchange or cancellation, as provided in this Article 2. If
                  any Global Note is to be exchanged for other Notes or canceled
                  in part, or if another Note is to be exchanged in whole or in
                  part for a beneficial interest in any Global Note, in each
                  case, as provided in Section 2.07, then either (A) such Global
                  Note shall be so surrendered for exchange or cancellation, as
                  provided in this Article 2, 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 Note to be so exchanged
                  for a beneficial interest therein, as the case may be, by
                  means of an appropriate

                                       15
<Page>

                  adjustment made on the records of the 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 Note, the Trustee shall,
                  as provided in this Article 2, authenticate and deliver any
                  Notes issuable in exchange for such Global Note (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 Notes that are
                  not in the form of Global Notes. 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 2 if such order, direction or request
                  is given or made in accordance with the Applicable Procedures.

                           (iv) Every Note authenticated and delivered upon
                  registration of transfer of, or in exchange for or in lieu of,
                  a Global Note or any portion thereof, whether pursuant to this
                  Article 2 or otherwise, shall be authenticated and delivered
                  in the form of, and shall be, a registered Global Note, unless
                  such Note is registered in the name of a Person other than the
                  Depositary for such Global Note or a nominee thereof, in which
                  case such Note shall be authenticated and delivered in
                  definitive, fully registered form, without interest coupons.

         The Depositary or its nominee, as registered owner of a Global Note,
shall be the Holder of such Global Note for all purposes under this Indenture
and the Notes, and owners of beneficial interests in a Global Note shall hold
such interests pursuant to the Applicable Procedures. Accordingly, any such
owner's beneficial interest in a Global Note 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 Note will not be considered the owners or holders thereof.

                  (2) NON-GLOBAL NOTES. Notes issued upon the events described
         in Section 2.06(1)(ii) shall be in definitive, fully registered form,
         without interest coupons.

         Section 2.07 REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

                  (1) Upon surrender for registration of transfer of any Note at
         an office or agency of the Company designated pursuant to Section 2.03
         for such purpose,

                                       16
<Page>

         the Company shall execute, and the Trustee shall authenticate and
         deliver, in the name of the designated transferee or transferees, one
         or more new Notes 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 2.07, Notes may be exchanged for other Notes of any authorized
denomination and of a like aggregate principal amount, upon surrender of the
Notes to be exchanged at any such office or agency. Whenever any Notes are so
surrendered for exchange, and subject to the other provisions of this Section
2.07, the Company shall execute, and the Trustee shall authenticate and deliver,
the Notes which the Holder making the exchange is entitled to receive. Every
Note presented or surrendered for registration of transfer or for exchange shall
(if so required by the Company or the Registrar) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company, the Trustee and the Registrar duly executed by the Holder thereof or
his attorney duly authorized in writing.

         All Notes issued upon any registration of transfer or exchange of Notes
shall be the legal, valid and binding obligations of the Company, evidencing the
same debt and entitled to the same benefits under this Indenture as the Notes
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 Notes except as provided in Section 2.08, 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 Notes, other than exchanges pursuant to
Sections 2.06, 9.05, 10.02 or 11.03 hereof, except where the shares of Common
Stock are to be issued or delivered in a name other than that of the Holder.

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

                  (2) Certain Transfers and Exchanges. Notwithstanding any other
         provision of this Indenture or the Notes, transfers and exchanges of
         Notes and beneficial interests in a Global Note of the kinds specified
         in this Section 2.07(2) shall be made only in accordance with this
         Section 2.07(2).

                           (i) A beneficial interest in a Global Note may be
                  exchanged for a Non-global Note only as provided in Section
                  2.06(1)(ii).

                                       17
<Page>

                  (3) 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 2.08 REPLACEMENT NOTES. If any mutilated Note is surrendered to
the Trustee or the Company or the Trustee receives evidence to its satisfaction
of the destruction, loss or theft of any Note, the Company shall issue and the
Trustee, upon receipt of an Authentication Order, shall authenticate a
replacement Note if the Trustee's requirements are met. If required by the
Trustee or the Company, an indemnity bond must be supplied by the Holder that is
sufficient in the judgment of the Trustee and the Company to protect the
Company, the Trustee, any Agent and any authenticating agent from any loss that
any of them may suffer if a lost, stolen or destroyed Note is replaced. The
Company and the Trustee may charge for their expenses in replacing a Note.

         Every replacement Note is an additional legally binding obligation of
the Company and shall be entitled to all of the benefits of this Indenture
equally and proportionately with all other Notes duly issued hereunder.

Section 2.09 OUTSTANDING NOTES. The Notes outstanding at any time are all the
Notes authenticated by the Trustee except for those canceled by it, those
delivered to it for cancellation, those reductions in the interest in a Global
Note effected by the Trustee in accordance with the provisions of this
Indenture, and those described in this Section as not outstanding. Except as set
forth in Section 2.10, a Note does not cease to be outstanding because either of
the Company or an Affiliate of the Company holds the Note.

         If a Note is replaced pursuant to Section 2.08, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

         If the principal amount of any Note is considered paid under Section
4.01, it ceases to be outstanding and interest on it ceases to accrue.

         If the Paying Agent (other than the Company, a Subsidiary of the
Company or an Affiliate of any thereof) holds, on a Redemption Date, Repurchase
Date or date of maturity, money, or in the case of a repurchase upon the
occurrence of a Change of Control and subject to the conditions set forth in
Article 11, or in the case of a Provisional Redemption and subject to the
conditions set forth in Section 3.12, shares of Common Stock, sufficient to pay
Notes payable on that date, then on and after that date such Notes shall be
deemed to be no longer outstanding and shall cease to accrue interest.

                                       18
<Page>

         If a Note is converted into Common Stock pursuant to Article 10, it
ceases to be outstanding and interest on it ceases to accrue on the day of
surrender of such Note for Conversion.

         Section 2.10 TREASURY NOTES. In determining whether the Holders of the
required principal amount of Notes have concurred in any direction, waiver or
consent, or whether the Holders of the requisite principal amount of then
outstanding Notes are present at a meeting of Holders for quorum purposes, Notes
owned by the Company, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company, shall
be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, or any such determination as to the presence of a
quorum, only Notes that a Responsible Officer of the Trustee actually knows are
so owned shall be so disregarded.

         Section 2.11 TEMPORARY NOTES. Until certificates representing Notes are
ready for delivery, the Company may prepare and the Trustee, upon receipt of an
Authentication Order, shall authenticate temporary Notes. Temporary Notes shall
be substantially in the form of certificated Notes but may have variations that
the Company considers appropriate for temporary Notes and as shall be reasonably
acceptable to the Trustee. Without unreasonable delay, the Company shall prepare
and the Trustee shall authenticate definitive Notes in exchange for temporary
Notes.

         Holders of temporary Notes shall be entitled to all of the benefits of
this Indenture.

         Section 2.12 CANCELLATION. The Company at any time may deliver Notes to
the Trustee for cancellation. The Registrar, Conversion Agent and Paying Agent
shall forward to the Trustee any Notes surrendered to them for registration of
transfer, exchange, conversion or payment. The Trustee and no one else shall
cancel any Notes surrendered for registration of transfer, exchange, conversion,
payment, replacement or cancellation and shall dispose of such canceled Notes in
its customary manner. The Company may not issue new Notes to replace Notes that
they have paid or that have been delivered to the Trustee for cancellation.

         Section 2.13 DEFAULTED INTEREST. If the Company defaults in a payment
of interest on the Notes, it shall pay the defaulted interest in any lawful
manner plus, to the extent lawful, interest payable on the defaulted interest,
to the Persons who are Holders on a subsequent special record date, in each case
at the rate provided in the Notes and in Section 4.01. The Company shall notify
the Trustee in writing of the amount of defaulted interest proposed to be paid
on each Note and the date of the proposed payment. The Company shall fix or
cause to be fixed each such special record date and payment date; provided that
no such special record date shall be less than 10 days prior to the related

                                       19
<Page>

payment date for such defaulted interest. At least 15 days before the special
record date, the Company (or, upon the written request of the Company, the
Trustee in the name and at the expense of the Company) shall mail or cause to be
mailed to Holders a notice that states the special record date, the related
payment date and the amount of such interest to be paid.

         Section 2.14 COMPUTATION OF INTEREST. Interest on the Notes shall be
computed on the basis of a 360-day year of twelve 30-day months.

         Section 2.15 CUSIP NUMBERS. The Company in issuing the Notes may use
"CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Holders; provided
that any such notice may state that no representation is made as to the
correctness of such numbers either as printed in the Notes or as contained in
any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such redemption shall not
be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the "CUSIP" numbers.

                                    ARTICLE 3

                            REDEMPTION AND PREPAYMENT

         Section 3.01 NOTICES TO TRUSTEE. If the Company elects to redeem Notes
pursuant to the redemption provisions of Sections 3.08 or 3.09, it shall furnish
to the Trustee, at least 45 days but not more than 60 days before a Redemption
Date, an Officers' Certificate setting forth (i) the paragraph of the Notes or
the clause of this Indenture pursuant to which the redemption shall occur, (ii)
the Redemption Date, (iii) the principal amount of Notes to be redeemed and (iv)
the Redemption Price.

         Section 3.02 SELECTION OF NOTES TO BE REDEEMED. If less than all of the
Notes are to be redeemed or purchased in an offer to purchase at any time, the
Trustee shall select the Notes to be redeemed or purchased among the Holders of
the Notes in compliance with the requirements of the principal national
securities exchange, if any, on which the Notes are listed or, if the Notes are
not so listed, on a pro rata basis, by lot or in accordance with any other
method the Trustee considers fair and appropriate. In the event of partial
redemption by lot, the particular Notes to be redeemed shall be selected, unless
otherwise provided herein, not less than 30 nor more than 60 days prior to the
Redemption Date by the Trustee from the then outstanding Notes not previously
called for redemption. If any Note selected for partial redemption is converted
in part before termination of the conversion right with respect to the portion
of the Note so selected, the converted portion of such Note shall be deemed (so
far as may be) to be the portion selected for redemption. Notes which have been
converted during a selection of Notes to

                                       20
<Page>

be redeemed may be treated by the Trustee as outstanding for the purpose of such
selection.

         The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of U.S. $1,000 or whole multiples of U.S.
$1,000; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of Notes held by such Holder, even if not a multiple
of U.S. $1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

         Section 3.03 NOTICE OF REDEMPTION. At least 30 days but not more than
60 days before a Redemption Date, the Company shall mail or cause to be mailed,

                  (d) the name and address of the Paying Agent;

                  (e) that Notes called for redemption must be surrendered to

                  (g) the paragraph of the Notes and/or Section of this

                  (i) the Conversion Rate, the date on which the right to
         convert the Notes to be redeemed will terminate and the places where
         Notes may be surrendered for conversion or the procedures for
         surrendering Notes;

                  (j) whether the redemption is a Provisional Redemption or an
         Optional Redemption;

                  (k) if such a redemption is a Provisional Redemption, the
         amount of the Make-Whole Payment; and

                  (l) whether the Make-Whole Payment will be paid in Common
         Stock, cash or a combination of cash and Common Stock.

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 45 days prior to the
Redemption Date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

         Section 3.04 EFFECT OF NOTICE OF REDEMPTION. Once notice of redemption
is mailed in accordance with Section 3.03, Notes called for redemption become
irrevocably due and payable on the Redemption Date at the Redemption Price. A
notice of redemption may not be conditional.

         Section 3.05 DEPOSIT OF REDEMPTION PRICE. At or prior to 10:00 a.m.,
New York City time, on the Redemption Date, the Company shall deposit with
the Trustee or with the Paying Agent (if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 2.04) (I) an
amount of money (which shall be in immediately available funds on such
Redemption Date) sufficient to pay the Redemption Price of and accrued
interest on all Notes to be redeemed on that date and (II) with respect to
Notes called for Provisional Redemption pursuant to Section 3.08, an amount
of money (which shall be in immediately available funds on such Redemption
Date) or, if the Company has satisfied the conditions of Section 3.12, Common
Stock sufficient to pay the Make-Whole Payment for all the Notes (or portions
thereof) called for redemption (including those surrendered for conversion
into Common Stock after the Notice Date and prior to the Redemption Date in
respect thereof). The Trustee or the Paying Agent shall promptly return to
the Company any money deposited with the Trustee or the Paying Agent by the
Company or so segregated and held in trust for the redemption of such Notes
in excess of the amounts, including but not limited to any amounts in respect
of Notes that are converted (subject to Section 10.02), necessary to pay the
Redemption Price of, and accrued interest on, all Notes to be redeemed;
provided that, with respect to a Provisional Redemption, any money or Common
Stock so deposited for payment of the Make-Whole Payment shall remain
segregated and held in trust for payment of the Make-Whole Payment which
shall be made on all Notes called for Provisional Redemption (including

                                       22
<Page>

Notes converted into Common Stock after the Notice Date and prior to the
Redemption Date in respect of such Provisional Redemption).

         Section 3.06 NOTES PAYABLE ON REDEMPTION DATE.

         (a) Notice of redemption having been given pursuant to Section 3.03,
the Notes so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and, with respect to Notes
called for Provisional Redemption, the Make-Whole Payment, and from and after
such date (unless the Company shall default in the payment of the Redemption
Price, including accrued interest or the Make-Whole Payment, if any) such Notes
shall cease to bear or accrue any interest. Upon surrender of any such Note for
redemption in accordance with said notice, such Note shall be paid by the
Company at the Redemption Price, together with any accrued and unpaid interest
to (but not including) the Redemption Date and, with respect to Notes called for
Provisional Redemption (including Notes converted into Common Stock pursuant to
the terms hereof after the Notice Date and prior to the Redemption Date in
respect thereof), the Make-Whole Payment; provided, however, that installments
of accrued and unpaid interest whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Notes, or one or more
Predecessor Notes, registered as such at the close of business on the relevant
Regular Record Date according to their terms and the terms of this Indenture;
and provided further that, with respect to a Provisional Redemption, the Holder
of any Notes converted into Common Stock pursuant to the terms of this Indenture
after the Notice Date and prior to the Redemption Date in respect thereof shall
have the right to the Make-Whole Payment, if any, with respect to such Notes
regardless of the conversion of such Notes.

         If the Company shall fail to deposit the Redemption Price (and
Make-Whole Payment, if any) with the Trustee and any Note called for redemption
shall not be so paid upon surrender thereof for redemption, the principal and
premium, if any (including the Make-Whole Payment, if any) shall, until paid,
bear and accrue interest from the Redemption Date at the rate provided in the
Note and in Section 4.01.

         (b) Any issuance of shares of Common Stock in respect of the Make-Whole
Payment shall be deemed to have been effected immediately prior to the close of
business on the Redemption Date 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 Redemption Date the
holder or holders of record of the shares of Common Stock represented thereby.

         (c) No fractions of shares shall be issued upon Provisional Redemption
of Notes. If more than one Note shall be so redeemed from the same Holder and
all or any portion of the Make-Whole Payment shall be payable in shares of
Common Stock, the number of full shares which shall be issuable upon such
repurchase shall be computed on

                                       23
<Page>

the basis of the aggregate principal amount of the Notes so repurchased. Instead
of any fractional share of Common Stock which would otherwise be issuable on the
Provisional Redemption of any Note or Notes, the Company shall calculate and pay
a cash adjustment in respect of such fraction (calculated to the nearest 1/100th
of a share) or round up the number of shares of Common Stock issuable upon
payment of the Make-Whole Payment to the nearest whole share. The value of a
fraction of a share shall be determined by multiplying the value of a share of
Common Stock for purposes of the Provisional Redemption, as computed in
accordance with Section 3.08, by the fraction, and rounding the result to the
nearest cent.

         (d) Any issuance and delivery of certificates for shares of Common
Stock on Provisional Redemption of Notes shall be made without charge to the
Holder subject to such Provisional Redemption 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 which 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 the name other than that of the Holder of the Notes being
redeemed, 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.

         Section 3.07 NOTES REDEEMED IN PART. Upon surrender of a Note that is
redeemed in part, the Company shall issue and, upon the Company's written
request, the Trustee shall authenticate for the Holder at the expense of the
Company a new Note equal in principal amount to the unredeemed portion of the
Note surrendered.

         Section 3.08 PROVISIONAL REDEMPTION. (a) Prior to ________, 2005, if
the Closing Price of the Common Stock shall have exceeded 150% of the Conversion
Price then in effect for at least 20 Trading Days in any consecutive 30-day
Trading Day period ending on the Trading Day prior to the date mailing of the
notice of Provisional Redemption pursuant to Section 3.03 (the "Notice Date"),
the Company may redeem the Notes ("Provisional Redemption"), in whole or from
time to time in part, upon not less than 30 nor more than 60 days' notice prior
to the Redemption Date, at a Redemption Price equal to the principal amount of
the Notes to be redeemed plus accrued and unpaid interest, if any, to the
Redemption Date. Upon any such Provisional Redemption, the Company shall make an
additional payment (the "Make-Whole Payment") in cash or, at the election of the
Company upon satisfaction of the conditions in Section 3.12, in Common Stock or
a combination of cash and Common Stock, as specified in the notice of
redemption, with respect to the Notes called for redemption to Holders on the
Notice Date in an amount equal to $___ per $1,000 aggregate principal amount of
Notes, less the amount of any interest actually paid or accrued and unpaid since
the Issue Date on each $1,000 aggregate principal amount of Notes so redeemed
(including any predecessor

                                       24
<Page>

Notes) prior to the Redemption Date. The Company shall make the Make-Whole
Payment on all Notes called for Provisional Redemption, including any Notes
converted into Common Stock pursuant to the terms of this Indenture after the
Notice Date and prior to the Redemption Date. For purposes of this paragraph,
the payments made in Common Stock will be determined by the Company and each
share of Common Stock to be delivered shall be valued at an amount equal to
95% of the average of the Closing Price Per Share of the Common Stock for the
five consecutive Trading Days immediately preceding and including the third
Trading Day prior to the Redemption Date.

         (b) Any redemption pursuant to this Section 3.08 shall be made pursuant
to the provisions of Section 3.01 through 3.07.

         Section 3.09 OPTIONAL REDEMPTION. The Company shall not have the option

and thereafter is equal to 100% of the principal amount, in each case together
with accrued and unpaid interest to the applicable Redemption Date.

         (a) Any redemption pursuant to this Section 3.09 shall be made pursuant
to the provisions of Section 3.01 through 3.07.

         Section 3.10 CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION. In
connection with any redemption of Notes, the Company may arrange for the
purchase and conversion of any Notes by an agreement with one or more investment
banks or other purchasers (the "Arrangement Purchasers") to purchase such
securities by such Arrangement Purchasers 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 interest accrued to the Redemption
Date of such Notes, and, in connection with a Provisional Redemption, the
Make-Whole Payment. Notwithstanding anything to the contrary contained in this
Article 3, the obligation of the Company to pay the Redemption Price, together
with the interest accrued to the Redemption Date, and, in connection with a
Provisional Redemption, the Make-Whole Payment, shall be deemed to be satisfied
and discharged to the extent such amount is so paid by such Arrangement

                                       25
<Page>

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 Notes 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 Arrangement Purchasers, to be acquired by
such Arrangement Purchasers from such Holders and (notwithstanding anything to
the contrary contained in Article 10) surrendered by such Arrangement Purchasers
for conversion, all as of immediately prior to the close of business on the
Redemption Date (and the right to convert any such Notes shall be extended
through such time), subject to payment of the above amount as aforesaid,
including the Make-Whole Payment, if any, with respect to all Notes called for
Provisional Redemption. At the direction of the Company, the Trustee shall hold
and dispose of any such amount paid to it by the Arrangement Purchasers to the
Holders in the same manner as it would monies deposited with it by the Company
for the redemption of Notes. Without the Trustee's prior written consent, no
arrangement between the Company and such Arrangement Purchasers for the purchase
and conversion of any Notes 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
Notes between the Company and such Arrangement 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.

         Section 3.11 MANDATORY REDEMPTION. The Company shall not be required to

         Section 3.12 CONDITIONS TO THE COMPANY'S ELECTION TO PAY THE MAKE-WHOLE

Make-Whole Payment by delivery of shares of Common Stock if and only if the
following conditions shall have been satisfied:

                  (a) the shares of Common Stock deliverable in payment of
         the Make-Whole Payment shall have a fair market value, as determined
         in the following sentence, as of the Redemption Date of not less
         than the amount of the Make-Whole Payment being paid in Common
         Stock. For purposes of this Section 3.12, the fair market value of
         shares of Common Stock shall be equal to 95% of the average of the
         Closing Price Per Share for the five consecutive Trading Days
         immediately preceding and including the third Trading Day prior to
         the Redemption Date in respect of such Provisional Redemption as
         determined by the Company;

<Page>

                  (b) in the event any shares of Common Stock to be issued
         upon redemption of Notes under Section 3.08 (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 redemption, such registration is
         effective prior to the Redemption Date in respect of such
         Provisional Redemption, 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, such registration is effective or such
         approval is obtained prior to the Redemption Date in respect of such
         Provisional Redemption (it being understood that, in the case of
         this clause (ii) only, if (with respect to any particular holder)
         (x) the Company has been unable so to effect such registration or
         obtain such approval after having used its reasonable best efforts
         to do so and, as a result, such Holder would be unable to receive
         shares of Common Stock or would receive shares of Common Stock that
         are not free from restrictions on transfer and (y) the Company pays
         the full amount of the Make-Whole Payment to such Holder in cash as
         provided in Section 3.08, the condition set forth in this clause
         (ii) will be deemed to be satisfied);

                  (c) the Common Stock is, or shall have been, approved for
         listing on the New York Stock Exchange or another national
         securities exchange, or approval for quotation on the Nasdaq National
         Market or, in any such case, prior to the Redemption Date in respect
         of such Provisional Redemption; and

                  (d) all shares of Common Stock which may be issued upon
         Provisional Redemption of Notes are issued out of the Company's
         authorized but unissued Common Stock and, upon issuance, will be
         duly and validly issued and fully paid and non-assessable and free
         of any preemptive or similar rights.

         Prior to making all or any portion of a Make-Whole Payment in Common
Stock, the Company shall certify to the Trustee in an Officer's Certificate that
all of the conditions set forth in this Section 3.12 are satisfied in accordance
with the terms thereof and shall deliver to the Trustee an opinion of counsel to
the Company to the effect that the shares of Common Stock to be issued upon
Provisional Redemption are not subject to any restrictions on transfer under the
Securities Act.

repurchase, registration of transfer or for exchange and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be

change in the location of any such other office or agency.

compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

         Section 4.04 COMPLIANCE CERTIFICATE.

the extent that it may lawfully do so) that it shall not at any time insist

Significant Subsidiaries; provided, however, that the Company shall not be
required to preserve any such right, license or franchise, or the corporate,

Board of Directors of the Company shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Company and its
Significant Subsidiaries, taken as a whole, and that the loss thereof is not
adverse in any material respect to the Holders.

         Section 4.08 PAYMENTS FOR CONSENT. The Company shall not, and shall not
permit any of its Subsidiaries to, directly or indirectly, pay or cause to be

particular instance to comply with any covenant or condition set forth in
Section 4.05 or 4.07 (other than with respect to the existence of the Company
(subject to Article 5)) (other than a covenant or condition which under Article
9 cannot be modified or amended without the consent of the Holder of each
outstanding Note affected), if before the time for such compliance the Holders
shall either (i) through the written consent (or as

                                       30
<Page>

otherwise in accordance with the Applicable Procedures) of the Holders of at
least a majority in aggregate principal amount of the Notes then outstanding or
(ii) by the adoption of a resolution, at a meeting of Holders of the then
outstanding Notes at which a quorum is present, by the Holders of at least 66?%
in principal amount of the outstanding Notes represented at such meeting or, if
less, by the Holders of at least a majority in aggregate principal amount of all
then outstanding Notes, 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.

substantially all of its properties or assets, in one or more related
transactions, to any other Person.

         may exercise every right and power of, the Company under this Indenture
         with the same effect as if such successor Person had been named therein
         as the Company, and (except in the case of a lease) the Company shall
         be released from the obligations under the Notes and this Indenture,
         except with respect to any obligations that arise from, or are related

                                    ARTICLE 6

                              DEFAULTS AND REMEDIES

         Section 6.01 EVENTS OF DEFAULT. An "Event of Default" occurs if:

                  (a) the Company defaults in the payment when due of interest
         on the Notes and such default continues for a period of 30 days,
         whether or not such payment is prohibited by the subordination
         provisions of the Notes or of this Indenture;

                  (b) the Company defaults in payment when due of the principal
         of or premium, if any (including the Make-Whole Payment, if any), on
         the Notes, whether or not such payment is prohibited by the
         subordination provisions of the Notes or of this Indenture;

                  (c) the Company fails to comply with any of the notice or
         repurchase provisions of Article 11, whether or not the compliance with
         such notice or repurchase provisions is prohibited by the subordination
         provisions of the Notes or of this Indenture;

                  (d) the Company fails to deliver shares of Common Stock,
         together with cash instead of fractional shares, when those shares of
         Common Stock or

                                       32
<Page>

         cash instead of fractional shares are required to be delivered
         following conversion of a Note pursuant to the provisions of Article 10
         and that failure continues for 10 days;

                  (e) the Company fails to comply with any of its other
         covenants or agreements in this Indenture for 60 days after written
         notice thereof has been given to the Company by the Trustee or to the
         Company and the Trustee by Holders of at least 25% of the aggregate
         principal amount of the then outstanding Notes;

                  (f) the Company or any of its Significant Subsidiaries
         defaults under any mortgage, indenture or instrument under which there
         may be issued or by which there may be secured or evidenced any
         Indebtedness for money borrowed (or the payment of which is guaranteed
         by the Company or any of its Significant Subsidiaries) whether such
         Indebtedness or guarantee now exists or is created after the Issue
         Date, if that default:

                           (1) is caused by a failure to pay at final stated
                  maturity the principal amount on such Indebtedness by the end
                  of the applicable grace period provided in such Indebtedness
                  on the date of such default (a "Payment Default"); or

                           (2) results in the acceleration of such Indebtedness
                  prior to its express maturity,

         and, in each case, the principal amount of any such Indebtedness,
         together with the principal amount of any other such Indebtedness under
         which there has been a Payment Default or the maturity of which has
         been so accelerated, aggregates $15 million or more, and (1) the
         indebtedness is not discharged, or (2) the acceleration is not
         annulled, within 30 days after written notice of such Event of Default
         to the Company by the Trustee or the holders of at least 25% in
         aggregate principal amount of the then outstanding Notes;

                  (g) the Company or any of its Significant Subsidiaries
         pursuant to or within the meaning of Bankruptcy Law:

                           (i) commences a voluntary case,

                           (ii) consents to the entry of an order for relief
                  against it in an involuntary case,

                           (iii) consents to the appointment of a custodian of
                  it or for all or substantially all of its property, or

                                       33
<Page>

                           (iv) makes a general assignment for the benefit of
                  its creditors; or

                  (h) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that:

                           (i) is for relief against the Company or any of its
                  Significant Subsidiaries in an involuntary case;

                           (ii) appoints a custodian of the Company or any of
                  its Significant Subsidiaries or for all or substantially all
                  of the property of the Company or any of its Significant
                  Subsidiaries; or

                           (iii) orders the liquidation of the Company or any of
                  its Significant Subsidiaries;

         and the order or decree remains unstayed and in effect for 60
         consecutive days.

         Section 6.02 ACCELERATION. In the case of an Event of Default arising
from clause (f) or (g) of Section 6.01 with respect to the Company, all then
outstanding Notes shall, subject to the provisions of Article 14, become due and
payable immediately without further action or notice. If any other Event of
Default occurs and is continuing, the Trustee by notice to the Company or the
Holders of at least 25% in principal amount of the then outstanding Notes by
notice to the Company and the Trustee may, subject to the provisions of Article
14, declare all the Notes to be due and payable immediately. The Holders of a
majority in aggregate principal amount of the Notes then outstanding by written
notice to the Trustee may on behalf of all of the Holders rescind an
acceleration and its consequences if:

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

                           (i) all overdue interest on all the Notes,

                           (ii) the principal of and premium, if any (including
                  the Make-Whole Payment, if any), on the Notes which have
                  become due otherwise than by such declaration of acceleration
                  and any interest thereon at the rate borne by the Notes,

                           (iii) to the extent permitted by applicable law,
                  interest upon overdue interest at a rate of 5% per annum, and

                                       34
<Page>

                           (iv) 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 any premium and interest on, the Notes which have
         become due solely by such declaration of acceleration, have been cured
         or waived as provided in Section 6.04; 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 6.02(1).

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

         Section 6.03 OTHER REMEDIES. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal, premium, if any (including the Make-Whole Payment, if any), and
interest on the Notes or to enforce the performance of any provision of the
Notes or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default. All remedies are cumulative
to the extent permitted by law.

         Section 6.04 WAIVER OF EXISTING DEFAULTS. Holders, either (i) through
the written consent (or as otherwise in accordance with the Applicable
Procedures) of the Holders of at least a majority in aggregate principal amount
of the then outstanding Notes by notice to the Trustee or (ii) by the adoption
of a resolution, at a meeting of Holders of the outstanding Notes at which a
quorum is present, by the Holders of at least 66?% in principal amount of the
then outstanding Notes represented at such meeting or, if less, by the Holders
of at least a majority in aggregate principal amount of all then outstanding
Notes by notice to the Trustee, may on behalf of the Holders of all of the Notes
waive an existing Default or Event of Default and its consequences hereunder,
except (x) a continuing Default or Event of Default in the payment of the
principal of, premium, if any (including the Make-Whole Payment, if any), or
interest on, the Notes (including in connection with a Change of Control Offer),
(y) a continuing Default or Event of Default in respect of a Holder's right to
convert any Note in accordance with Article 10 or (z) in respect of a covenant
or provision hereof which under Article 9 cannot be modified or amended without
the consent of each Holder of each outstanding Note affected

                                       35
<Page>

(provided, however, that the Holders of a majority in aggregate principal amount
of the then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration).
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 6.05 CONTROL BY MAJORITY. Subject to Section 7.02, holders of a
majority in principal amount of the then outstanding Notes may direct the time,
method and place of conducting any proceeding for exercising any remedy
available to the Trustee or exercising any trust or power conferred on it.
However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture, that the Trustee determines may be prejudicial to the rights
of other Holders or that may involve the Trustee in personal liability. The
Trustee may take any other action which it deems proper that is not inconsistent
with any such directive.

         Section 6.06 LIMITATION ON SUITS. No Holder will have any right to
institute any proceeding under this Indenture, or for the appointment of a
receiver or a trustee or for any other remedy under this Indenture or the Notes
unless:

                  (a) the Holder gives to the Trustee written notice of a
         continuing Event of Default;

                  (b) the Holders of at least 25% in aggregate principal amount
         of the then outstanding Notes make a written request to the Trustee to
         pursue the remedy;

                  (c) such Holder or Holders offer and, if requested, provide to
         the Trustee indemnity reasonably satisfactory to the Trustee against
         any loss, liability or expense;

                  (d) the Trustee does not comply with the request within 60
         days after the later of (1) receipt of the request (specified in
         clause (b) above), and the offer (specified in clause (c) above),
         and (2) if requested, the provision of indemnity (specified in
         clause (c) above); and

                  (e) during such 60-day period the Holders of a majority in
         principal amount of the then outstanding Notes do not give the Trustee
         a direction inconsistent with the request and offer.

         A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over another Holder.

         Section 6.07 RIGHTS OF HOLDERS TO RECEIVE PAYMENT AND TO CONVERT.
Notwithstanding any other provision of this Indenture, but subject to the
provisions of

                                       36
<Page>

Article 14, the right of any Holder to receive payment of principal, premium, if
any (including the Make-Whole Payment, if any), and interest on a Note, on or
after the Maturity dates (including in connection with a redemption or a Change
of Control Offer), or to convert such Note in accordance with Article 10, or to
bring suit for the enforcement of any such payment on or after such respective
dates or of such right to convert, shall be absolute and unconditional and shall
not be impaired or affected without the consent of such Holder.

         Section 6.08 COLLECTION SUIT BY TRUSTEE. If an Event of Default
specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is
authorized to recover judgment in its own name and as trustee of an express
trust against the Company for the whole amount of principal of, premium, if any
(including the Make-Whole Payment, if any), and interest remaining unpaid on the
Notes and interest on overdue principal and, to the extent lawful, interest and
such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

         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 the Notes 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 6.09 TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee is
authorized to file such proofs of claim and other papers or documents 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 the Holders allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Notes), their
creditors or their property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder 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, 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 7.07. To the
extent that the payment of any such compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 out of the estate in any such proceeding, shall be
denied for any reason, payment of the same shall be secured by a lien on, and
shall be paid out of, any and all distributions, dividends, money, securities
and other properties that the Holders may be entitled to receive in such
proceeding whether in liquidation or under any plan of reorganization or
arrangement or

                                       37
<Page>

otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding.

         Section 6.10 TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES. All rights of action and claims under this Indenture or the Notes
may be prosecuted and enforced by the Trustee without the possession of any of
the Notes 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 in respect of which judgment has been recovered.

         Section 6.11 PRIORITIES. Subject to Article 14, if the Trustee collects
any money pursuant to this Article, it shall pay out the money in the following
order:

                  First: to the Trustee, its agents and attorneys for amounts
                  due under Section 7.07, including payment of all compensation,
                  expense and liabilities incurred, and all advances made, by
                  the Trustee and the costs and expenses of collection;

                  Second: to Holders for amounts due and unpaid on the Notes for
                  principal, premium, if any (including the Make-Whole Payment,
                  if any), and interest, ratably, without preference or priority
                  of any kind, according to the amounts due and payable on the
                  Notes for principal, premium, if any (including the Make-Whole
                  Payment, if any), and interest, respectively; and

                  Third: to the Company or to such party as a court of competent
                  jurisdiction shall direct.

         The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.11.

         Section 6.12 UNDERTAKING FOR COSTS. In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to

                                       38
<Page>

a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by
Holders of more than 10% in principal amount of the then outstanding Notes.

         If any Trustee or any Holder 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 such Holder, then, and in every case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Company, Trustee and the Holders shall
continue as though no such proceeding had been instituted.

                                    ARTICLE 7

                                     TRUSTEE

         Section 7.01 DUTIES OF TRUSTEE.

         (a) If 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 its exercise, as a prudent person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

         (b) Except during the continuance of an Event of Default:

                  (i) the duties of the Trustee shall be determined solely by
         the express provisions of this Indenture and the Trustee need perform
         only those duties that are specifically set forth in this Indenture and
         no others, and no implied covenants or obligations shall be read into
         this Indenture against the Trustee; and

                  (ii) 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 required to be furnished to the Trustee hereunder and
         conforming to the requirements of this Indenture. However, the Trustee
         shall examine the certificates and opinions to determine whether or not
         they conform to the requirements of this Indenture (but need not
         confirm or investigate the accuracy of any mathematical calculations or
         other facts stated therein).

         (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

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

                  (iii) the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.05.

this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), and (c) of this Section 7.01.

or risk its own funds or incur any liability. The Trustee shall be under no
obligation to exercise any of its rights and powers under this Indenture at the

the Trustee security and indemnity satisfactory to it against any loss,
liability, claim, damage or expense.

matter stated in the document.

Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel of its own selection and the written advice or opinion of such counsel
or any Opinion of Counsel shall be full and complete authorization and
protection from liability in respect of any action taken, suffered or omitted by
it hereunder in good faith and in reliance thereon.

signed by an Officer of the Company.

rights and powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity satisfactory to it against any loss, liability,
claim, damage or expense incurred by it in compliance with such request.

Event of Default unless either (i) a Responsible Officer of the Trustee shall
have actual knowledge of such Default or Event of Default or (ii) written notice
of such Default or Event of Default shall have been given by the Company or any
Holder and received by a Responsible Officer of the Trustee.

         Section 7.03 INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Company or any Affiliate of the Company with the
same rights it would have if it were not Trustee. However, in the event that the
Trustee acquires any conflicting interest it must eliminate such conflict within
90 days, apply to the Commission for permission to continue as trustee or
resign. Any Agent may do the same with like rights and duties. The Trustee is
also subject to Sections 7.10 and 7.11.

         Section 7.04 TRUSTEE'S DISCLAIMER. The Trustee shall not be responsible
for and makes no representation as to the validity or adequacy of this Indenture
or the Notes, it shall not be accountable for the Company's use of the proceeds
from the Notes or any money paid to the Company or upon the Company's direction
under any provision of this Indenture, it shall not be responsible for the use
or application of any money received by any Paying Agent other than the Trustee
or an Affiliate of the Trustee, and it shall not be responsible for any
statement or recital herein or any statement in the Notes or any other document
in connection with the sale of the Notes or pursuant to this Indenture other
than its certificate of authentication.

         Section 7.05 NOTICE OF DEFAULTS. If a Default or Event of Default
occurs and is continuing and if it is known to a Responsible Officer of the
Trustee, the Trustee shall mail to Holders a notice of the Default or Event of
Default within 90 days after the Trustee acquires knowledge thereof. Except in
the case of a Default or Event of Default in payment of principal of, premium,
if any (including the Make-Whole Payment, if any), or interest on any Note, the
Trustee may withhold the notice if and so long as a

                                       41
<Page>

committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of the Holders.

         Section 7.06 REPORTS BY TRUSTEE TO HOLDERS. Within 60 days after each
__ beginning with the __ following the date of this Indenture, and for so long
as Notes remain outstanding, the Trustee shall mail to the Holders a brief
report dated as of such reporting date that complies with TIA Section 313(a)
(but if no event described in TIA Section 313(a) has occurred within the twelve
months preceding the reporting date, no report need be transmitted). The Trustee
also shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by
mail all reports as required by TIA Section 313(c).

         A copy of each report at the time of its mailing to the Holders shall
be mailed to the Company and filed with the Commission and each stock exchange
on which the Notes are listed in accordance with TIA Section 313(d). The Company
shall promptly notify the Trustee when the Notes are listed on any stock
exchange or delisted therefrom.

         Section 7.07 COMPENSATION AND INDEMNITY. The Company shall pay to the
Trustee from time to time reasonable compensation for its acceptance of this
Indenture and services hereunder. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

         The Company shall fully indemnify the Trustee against any and all
losses, liabilities, claims, damages or expenses (including reasonable legal
fees and expenses) incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture against the Company (including
this Section 7.07) and defending itself against any claim (whether asserted by
the Company or any Holder or any other person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its gross
negligence or willful misconduct. The Trustee shall notify the Company promptly
of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder.
The Company shall defend the claim and the Trustee shall cooperate in the
defense. The Trustee may have separate counsel and the Company shall pay the
reasonable fees and expenses of such counsel. The Company need not pay for any
settlement made without its consent, which consent shall not be unreasonably
withheld.

resignation or removal of the Trustee and the satisfaction and discharge of this
Indenture.

                                       42

         To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal and
interest on particular Notes. Such lien shall survive the resignation or removal
of the Trustee and the satisfaction and discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(f) or (g) occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

         The Trustee shall comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

         Section 7.08 REPLACEMENT OF TRUSTEE. A resignation or removal of the
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section.

         The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of a majority
in principal amount of the then outstanding Notes may remove the Trustee by so
notifying the Trustee and the Company in writing. The Company may remove the
Trustee if:

                  (a) the Trustee fails to comply with Section 7.10;

                  (b) the Trustee is adjudged a bankrupt or an insolvent or an
         order for relief is entered with respect to the Trustee under any
         Bankruptcy Law;

                  (c) a custodian or public officer takes charge of the Trustee
         or its property; or

                  (d) the Trustee becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

         If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of at least 10% in principal amount of the then outstanding Notes
may petition at the expense of the Company any court of competent jurisdiction
for the appointment of a successor Trustee.

                                       43
<Page>

         If the Trustee, after written request by any Holder who has been a
Holder for at least six months, fails to comply with Section 7.10, such Holder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee; provided all sums owing to the
Trustee hereunder have been paid and subject to the lien provided for in Section
7.07. Notwithstanding replacement of the Trustee pursuant to this Section 7.08,
the Company's obligations under Section 7.07 shall continue for the benefit of
the retiring Trustee.

         Section 7.09 SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee
consolidates, merges or converts into, or transfers all or substantially all of
its corporate trust business to, another corporation, the successor corporation
without any further act shall be the successor Trustee.

         Section 7.10 ELIGIBILITY; DISQUALIFICATION. There shall at all times be
a Trustee hereunder that is a corporation organized and doing business under the
laws of the United States of America or of any state thereof that is authorized
under such laws to exercise corporate trust powers, that is subject to
supervision or examination by federal or state authorities and that has a
combined capital and surplus of at least $50 million as set forth in its most
recent published annual report of condition.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to
TIA Section 310(b).

         Section 7.11 PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY. The
Trustee is subject to TIA Section 311(a), excluding any creditor relationship
listed in TIA Section 311(b). A Trustee who has resigned or been removed shall
be subject to TIA Section 311(a) to the extent indicated therein.

         Section 7.12 OTHER CAPACITIES. All references in this Indenture to the
Trustee shall be deemed to refer to the Trustee in its capacity as Trustee and
in its capacities as Agent, to the extent acting under such capacities, and
every provision of this Indenture relating to the conduct or affecting the
liability or offering protection, immunity or indemnity to the Trustee shall be
deemed to apply with the same force and effect to the Trustee acting in its
capacities as any Agent.

         the meeting shall have been called by the Company or by Holders as
         provided in Section 8.02(2), in which case the Company or the Holders
         calling the meeting, as the case may be, shall in like manner appoint a
         temporary chairman. A permanent chairman and a permanent secretary of
         the meeting shall be elected by vote of the Persons entitled to vote a
         majority in principal amount of the then outstanding Notes represented

         represented by him or her; provided, however, that no vote shall be
         cast or counted at any meeting in respect of any Note challenged as not
         outstanding and ruled by the chairman of the meeting to be not
         outstanding. The chairman of the meeting shall have no right to vote,
         except as a Holder or proxy.

all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
duplicate of all votes cast at the meeting. A record, at least in duplicate, of
the proceedings of each meeting of Holders shall be prepared by the secretary of
the meeting and there shall be attached to said record the original reports of
the inspectors of votes on any vote by ballot taken thereat and affidavits by
one or more Persons having knowledge of the facts setting forth a copy of the

Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section

rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but shall not be obligated to, enter into
such amended or supplemental Indenture.

         It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment or
supplement, but it shall be sufficient if such consent approves the substance
thereof.

         After an amendment or supplement under this Section 9.02 becomes
effective, the Company shall mail to the Holders affected thereby a notice
briefly describing the amendment or supplement. Any failure of the Company to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such amended or supplemental Indenture.

         However, without the consent or affirmative vote of each Holder
affected, an amendment or supplement under this Section 9.02 may not (with
respect to any Notes held by a non-consenting Holder):

                                       49
<Page>

                  (a) change the Stated Maturity of the principal of, or any
         installment of interest on, any Note, or reduce the principal amount
         of, or the premium, if any (including the Make-Whole Payment, if any),
         or the rate of interest payable thereon, or reduce the amount payable
         upon a redemption or Change of Control, or change the place or currency
         of payment of the principal of, premium, if any (including the
         Make-Whole Payment, if any), or interest on any Note (including any
         payment of Redemption Price or Repurchase Price in respect of such
         Note) or impair the right to institute suit for the enforcement of any
         payment in respect of any Note on or after the Stated Maturity thereof
         (or, in the case of redemption or any repurchase, on or after the
         Redemption Date or Repurchase Date, as the case may be) or, except as
         permitted by Section 10.11, adversely affect the right of Holders to
         convert any Note as provided in Article 10 or modify the provisions of
         this Indenture with respect to the subordination of the Notes in a
         manner adverse to the Holders; or

                  (b) reduce the requirements of Section 8.04 for quorum or
         voting, or reduce the percentage in principal amount of the then
         outstanding Notes the consent of whose Holders is required for any such
         supplemental indenture or the consent of whose Holders is required for
         any waiver of compliance with certain provisions of this Indenture or
         certain defaults hereunder and their consequences provided for in this
         Indenture; or

                  (c) modify the obligation of the Company to maintain an office
         or agency in the Borough of Manhattan, The City of New York, pursuant
         to Section 4.02; or

                  (d) modify any of the provisions of this Section or Section
         4.10 or 6.04, except to increase any percentage contained herein or
         therein or to provide that certain other provisions of this Indenture
         cannot be modified or waived without the consent of the Holder of each
         outstanding Note affected thereby; or

                  (e) modify the provisions of Article 11 relating to notice and
         repurchase (including, without limitation, those relating to the
         Repurchase Date and the Repurchase Price (whether payable in cash or
         shares of Common Stock)) in a manner adverse to the Holders.

         Section 9.03 COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment or
supplement to this Indenture or the Notes shall be set forth in an amended or
supplemental Indenture that complies with the TIA as then in effect.

         Section 9.04 REVOCATION AND EFFECT OF CONSENTS. Until an amendment or
supplement becomes effective, a consent to it by a Holder is a continuing
consent by the Holder and every subsequent Holder that evidences the same debt
as the consenting

                                       50
<Page>

Holder's Note, even if notation of the consent is not made on any Note. However,
any such Holder or subsequent Holder may revoke the consent as to its Note if
the Trustee receives written notice of revocation before the date the supplement
or amendment becomes effective. An amendment or supplement becomes effective in
accordance with its terms and thereafter binds every Holder.

         Section 9.05 NOTATION ON OR EXCHANGE OF NOTES. The Trustee may place an
appropriate notation about an amendment or supplement on any Note thereafter
authenticated. The Company in exchange for all Notes may issue and the Trustee
shall, upon receipt of an Authentication Order, authenticate new Notes that
reflect the amendment or supplement.

         Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment or supplement.

         Section 9.06 TRUSTEE TO SIGN AMENDMENTS, ETC. The Trustee shall sign
any amended or supplemental Indenture authorized pursuant to this Article 9 if
the amendment or supplement does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. The Company may not sign an amendment
or supplemental Indenture until the Board of Directors approves it. In executing
any amended or supplemental indenture, the Trustee shall be entitled to receive
and (subject to Section 7.01) shall be fully protected in relying upon, in
addition to the documents required by Section 10.04, an Officer's Certificate
and an Opinion of Counsel stating that the execution of such amended or
supplemental indenture is authorized or permitted by this Indenture.

                                   ARTICLE 10

                               CONVERSION OF NOTES

         Section 10.01 CONVERSION PRIVILEGE AND CONVERSION RATE. Subject to and
upon compliance with the provisions of this Article, at the option of the Holder
thereof, any Note 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. Such conversion right shall commence on the
initial issuance date of the Notes and expire at the close of business on the
Business Day prior to the date of Maturity of the Notes, subject, in the case of
conversion of any Global Note, to any Applicable Procedures. In case a Note 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 Note
following a Change of Control, such conversion right in respect of the Note, or
portion thereof so called, shall expire at the close of business on the Business
Day prior to the Redemption Date or the Repurchase Date, as the case may be,
unless the Company

                                       51
<Page>

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 Note).

         The rate at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Rate") shall be initially ___ shares
of Common Stock for each U.S. $1,000 principal amount of Notes. The Conversion
Rate shall be adjusted in certain instances as provided in this Article 10.

         Section 10.02 EXERCISE OF CONVERSION PRIVILEGE. In order to exercise
the conversion privilege, the Holder of any Note to be converted shall
surrender such Note, duly endorsed in blank, at any office or agency of the
Company maintained for that purpose pursuant to Section 4.02, accompanied by
a duly signed conversion notice substantially in the form set forth in
Exhibit A stating that the Holder elects to convert such Note or, if less
than the entire principal amount thereof is to be converted, the portion
thereof to be converted. Each Note surrendered for conversion (in whole or in
part) during the period between the close of business during the Record Date
Period shall (except in the case of any Note or portion thereof which has
been called for redemption on a Redemption Date occurring within such Record
Date Period and, as a result, the right to convert would terminate in such
period) 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
the applicable Interest Payment Date on the principal amount of such Note (or
part thereof, as the case may be) being surrendered for conversion, provided
that if any Note (or portion thereof) has been called for redemption on a
Redemption Date occurring during the Record Date Period, and is surrendered
for conversion during such period, the Holder of such Note on the related
Regular Record Date will be entitled to receive the interest accruing on such
Note from the Interest Payment Date next preceding the date of such
conversion to such succeeding Interest Payment Date and the Holder of such
Note who converts such Note or portion thereof during such period shall not
be required to pay such interest upon surrender of such Note for conversion.
The interest so payable on such Interest Payment Date with respect to any
Note (or portion thereof, if applicable) which is surrendered for conversion
during the Record Date Period shall be paid to the Holder of such Note as of
such Regular Record Date in an amount equal to the interest that would have
been payable on such Note if such Note had been converted as of the close of
business on such Interest Payment Date. Except as provided in this paragraph,
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 Note (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 Note is convertible will be deemed
to satisfy the Company's obligation to pay the principal amount of the Note.

                                       52
<Page>

         Notes shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Notes for conversion in
accordance with the foregoing provisions, and at such time the rights of the
Holders of such Notes 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
promptly as practicable on or after the conversion date, the Company shall issue
and deliver to the Trustee, for delivery to the Holder, 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 10.03.

         In the case of any Note 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 Note or
Notes of authorized denominations in an aggregate principal amount equal to the
unconverted portion of the principal amount of such Note. A Note may be
converted in part, but only if the principal amount of such Note to be converted
is any integral multiple of U.S. $1,000 and the principal amount of such Note to
remain outstanding after such conversion is equal to U.S. $1,000 or any integral
multiple of U.S. $1,000 in excess thereof.

         Section 10.03 FRACTIONS OF SHARES. No fractional shares of Common Stock
shall be issued upon conversion of any Note or Notes. If more than one Note
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 Notes (or specified
portions thereof) so surrendered. Instead of any fractional share of Common
Stock which would otherwise be issuable upon conversion of any Note or Notes (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 (or round up the number of shares
of Common Stock issuable upon conversion of any Note or Notes to the nearest
whole share).

         Section 10.04 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 any class of capital 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
         shareholders 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

                                       53
<Page>

         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) Subject to the last sentence of paragraph (7) below, in
         case the Company shall issue rights, options or warrants to all or
         substantially all holders of its Common Stock entitling them to
         subscribe for or purchase shares of Common Stock, or securities
         convertible into 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 10.04) 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 Note
         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 which 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,

                                       54
<Page>

         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 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 or substantially 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 and any other rights, options or warrants that by their
         terms will also be issued to any Holder upon conversion of a Note into
         shares of Common Stock without any action required by the Company or
         any other Person, (ii) any dividend or distribution paid exclusively in
         cash, (iii) any dividend or distribution referred to in paragraph (1)
         of this Section and (iv) mergers or consolidations to which Section
         10.11 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
         10.04) 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

                                       55
<Page>

         Conversion Rate shall be immediately readjusted, effective as of the
         date 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 to all holders of its Common Stock exclusively cash
         (excluding any cash that is distributed as part of a distribution
         referred to in paragraph (4) of this Section or cash distributed upon a
         merger or consolidation to which Section 10.11 applies) in an aggregate
         amount that, combined together with (i) the aggregate amount of any
         such other all-cash distributions to all holders of its Common Stock
         within the 365-day period preceding the date of payment of such
         distribution and in respect of which no adjustment pursuant to
         paragraphs (5) and (6) of this Section 10.04 has been made and (ii) the
         aggregate of any cash plus the fair market value (as determined by the
         Board of Directors, whose determination shall be conclusive and
         described in a Board Resolution) of consideration payable in respect of
         any tender offer by the Company or any of its Subsidiaries for all or
         any portion of the Common Stock concluded within the 365-day period
         preceding the date of payment of such distribution and in respect of
         which no adjustment pursuant to paragraphs (5) and (6) of this Section
         10.04 has been made (the "combined cash and tender amount") exceeds
         10.0% of the product of the current market price per share (determined
         as provided in paragraph (8) of this Section 10.04) of the Common Stock
         on the date for the determination of holders of shares of Common Stock
         entitled to receive such distribution times the number of shares of
         Common Stock outstanding on such date (the "aggregate current market
         price"), then, and in each such case, immediately after the close of
         business on such date for determination, 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 determination of the 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 10.04) of the
         Common Stock on the date fixed for such determination less an amount
         equal to the quotient of (x) the excess of such combined cash and
         tender amount over such aggregate current market price divided by (y)
         the number of shares of Common Stock outstanding on such date for
         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 10.04) of the Common Stock on such date fixed for
         determination.

                  (6) In case a tender offer made by the Company or any
         Subsidiary for all or any portion of the Common Stock shall expire and
         such tender offer (as amended upon the expiration thereof) shall
         require the payment to stockholders (based on the acceptance (up to any
         maximum specified in the terms of the tender offer) of Purchased Shares
         (as defined below)) of an aggregate consideration

                                       56
<Page>

         having a fair market value (as determined by the Board of Directors,
         whose determination shall be conclusive and described in a Board
         Resolution) that combined together with (i) the aggregate of the cash
         plus the fair market value (as determined by the Board of Directors,
         whose determination shall be conclusive and described in a Board
         Resolution), as of the expiration of such tender offer, of
         consideration payable in respect of any other tender offer by the
         Company or any Subsidiary for all or any portion of the Common Stock
         expiring within the 365-day period preceding the expiration of such
         tender offer and in respect of which no adjustment pursuant to
         paragraphs (5) and (6) of this Section 10.04 has been made and (ii) the
         aggregate amount of any cash distributions to all holders of the Common
         Stock within the 365-day period preceding the expiration of such tender
         offer and in respect of which no adjustment pursuant to paragraphs (5)
         and (6) of this Section 10.04 has been made (the "combined tender and
         cash amount") exceeds 10.0% of the product of the current market price
         per share of the Common Stock (determined as provided in paragraph (8)
         of this Section 10.04) as of the last time (the "Expiration Time")
         tenders could have been made pursuant to such tender offer (as it may
         be amended) times the number of shares of Common Stock outstanding
         (including any tendered shares) as of the Expiration Time, then, and in
         each such case immediately prior to the opening of business on the day
         after the date of the Expiration Time, 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 date
         of the Expiration Time 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 10.04) on the date of the Expiration Time multiplied by (II)
         the number of shares of Common Stock outstanding (including any
         tendered shares) on the Expiration Time less (B) the combined tender
         and cash amount, 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 10.04)
         as of the Expiration Time multiplied by (B) the number of shares of
         Common Stock outstanding (including any tendered shares) as of the
         Expiration Time less the number of all shares validly tendered and not
         withdrawn as of the Expiration Time (the shares deemed so accepted up
         to any such maximum, being referred to as the "Purchased Shares").

                  (7) The reclassification of Common Stock into securities other
         than Common Stock (other than any reclassification upon a consolidation
         or merger to which Section 10.11 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 10.04), and (b) a subdivision or
         combination, as the case may be, of the number of

                                       57
<Page>

         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 10.04). Rights, options or warrants issued by the Company
         to all holders of its Common Stock entitling the holders thereof to
         subscribe for or purchase shares of capital stock of the Company, which
         rights, options or warrants (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 shares of capital stock, in
         each case in clauses (i) through (iii) until the occurrence of a
         specified event or events ("Trigger Event"), shall for purposes of this
         Section 10.04 not be deemed issued or distributed until the occurrence
         of the earliest Trigger Event.

                  (8) For the purpose of any computation under paragraph (2),
         (4), (5) or (6) of this Section 10.04, the current market price per
         share of Common Stock on any date shall be calculated by the Company
         and shall be the average of the daily Closing Price 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 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 the 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 Notes or any shorter term, in
         addition to those required by paragraphs (1), (2), (3), (4), (5) and
         (6) of this Section 10.04, 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

                                       58
<Page>

         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
         10.04, 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) In addition to increases in the Conversion Rate
         permitted pursuant to Paragraph (10) above, 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 (20) 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. 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 provided in Section 12.02 at least fifteen
         (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 10.05 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 10.04 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 12.02.

                                       59
<Page>

         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
desiring inspection thereof at its office during normal business hours, and
shall not be deemed to have knowledge of any adjustment in the Conversion Rate
unless and until a Responsible Officer of the Trustee shall have received such a
certificate. Until a Responsible Officer of the Trustee receives such a
certificate, the Trustee and each Conversion Agent may assume without inquiry
that the last Conversion Rate of which the Trustee has knowledge of remains in
effect.

         Section 10.06 NOTICE OF CERTAIN CORPORATE ACTION. In case:

                  (1) the Company shall declare a dividend (or any other
         distribution) on its Common Stock payable (i) otherwise than
         exclusively in cash or (ii) exclusively in cash in an amount that would
         require any adjustment pursuant to Section 10.04; 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 Notes pursuant to Section
         4.02, and shall cause to be provided to all Holders in accordance with
         Section 12.02, at least 20 days (or 10 days in any case specified in
         clause (1) or (2) 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

                                       60
<Page>

         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 10.06. 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 Notes pursuant
to Section 4.02, and shall cause to be provided to all Holders in accordance
with Section 12.02, 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 10.07 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 (including treasury stock), for the
purpose of effecting the conversion of Notes, the full number of shares of
Common Stock then issuable upon the conversion of all then outstanding Notes.

         Section 10.08 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
Notes pursuant hereto. The Company shall not, however, be required to pay any
tax or duty which may be payable in respect of any transfer involved in the
issue and delivery of shares of Common Stock in a name other than that of the
Holder of the Note or Notes 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 10.09 COVENANT AS TO COMMON STOCK. The Company agrees that all
shares of Common Stock which may be delivered upon conversion of Notes, upon
such delivery, will have been duly authorized and validly issued and will be
fully paid and nonassessable and, except as provided in Section 10.08, the
Company will pay all taxes, liens and charges with respect to the issue thereof.

         Section 10.10 CANCELLATION OF CONVERTED NOTES. All Notes 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 2.12.

                                       61
<Page>

         Section 10.11 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 or any merger of another Person with or into the Company (in
either case, other than a merger which 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, 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 Note then
outstanding shall have the right thereafter, during the period such Note
shall be convertible as specified in Section 10.01, to convert such Note 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
Note might have been converted immediately prior to such consolidation,
merger, conveyance, sale, transfer or lease, assuming such holder of Common
Stock (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 or her 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 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 10.11 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 which, 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 10.11 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 as
provided in Section 12.02 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 kind or amount of shares of
stock or other securities or property or cash receivable by Holders upon the
conversion of their Notes 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

                                       62
<Page>

protected in relying upon, an Opinion of Counsel with respect thereto, which the
Company shall cause to be furnished to the Trustee.

         Section 10.12 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 10.04(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
10.04(2), (1) in the case of any such rights or warrants which 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 10.13 RESPONSIBILITY OF TRUSTEE FOR CONVERSION PROVISIONS. The
Trustee, subject to the provisions of Section 7.01, and any Conversion Agent
shall not at any time be under any duty or responsibility to any Holder 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 7.01, 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 Notes or property or cash, which may at any time be issued or delivered
upon the conversion of any Note; and it or they do not make any representation
with respect thereto. Neither the Trustee, subject to the provisions of Section
7.01, nor any

                                       63
<Page>

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 other Notes or property or cash upon the
surrender of any Note for the purpose of conversion; and the Trustee, subject to
the provisions of Section 7.01, 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 11

                        REPURCHASE OF NOTES AT THE OPTION
                     OF THE HOLDER UPON A CHANGE OF CONTROL

         Section 11.01 RIGHT TO REQUIRE REPURCHASE. If a Change of Control
occurs, each Holder shall have the right, at the Holder's option, but subject to
the provisions of Section 11.02, to require the Company to repurchase, and upon
the exercise of such right the Company shall repurchase, all of such Holder's
Notes not theretofore called for redemption, or any portion of the principal
amount thereof that is equal to U.S. $1,000 or any integral multiple of U.S.
$1,000 in excess thereof (provided that no single Note may be repurchased in
part unless the portion of the principal amount of such Note to be outstanding
after such repurchase is equal to U.S. $1,000 or integral multiples of U.S.
$1,000 in excess thereof), pursuant to a Change of Control Offer. Upon the
occurrence of a Change of Control, the Company shall offer (a "Change of Control
Offer") a payment equal to 100% of the aggregate principal amount of the Notes
to be repurchased plus interest accrued and unpaid to but excluding the
Repurchase Date (the "Repurchase Price"); provided, however, that installments
of interest on Notes whose Stated Maturity is on or prior to the Repurchase Date
shall be payable to the Holders of such Notes, or one or more Predecessor Notes,
registered as such on the relevant Regular Record Date according to their terms.
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 Section
11.02, by delivery of shares of Common Stock having a fair market value equal to
the Repurchase Price. Whenever in this Indenture there is a reference, in any
context, to the principal of any Note as of any time, such reference shall be
deemed to include reference to the Repurchase Price payable in respect of such
Note 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; provided,
however, that for the purposes of Article 14, such reference shall be deemed to
include reference to the Repurchase Price only to the extent the Repurchase
Price is payable in cash.

         Section 11.02 CONDITIONS TO THE COMPANY'S ELECTION TO PAY THE
REPURCHASE PRICE IN COMMON STOCK. Except as provided in the last paragraph of
this Section 11.02, the

                                       64
<Page>

Company may elect to pay the Repurchase Price by delivery of shares of Common
Stock pursuant to Section 11.01 if and only if the following conditions shall
have been satisfied:

                  (1) the shares of Common Stock deliverable in payment of the
         Repurchase Price shall have a fair market value as of the Repurchase
         Date of not less than the Repurchase Price. For purposes of Section
         11.01 and this Section 11.02, the fair market value of shares of Common
         Stock shall be equal to 95% of the average of the Closing Price Per
         Share of the Common Stock for the five consecutive Trading Days
         immediately preceding and including the fifth Trading Day prior to the
         Repurchase Date as determined by the Company;

                  (2) in the event any shares of Common Stock to be issued upon
         repurchase of Notes under Section 11.01 (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, such registration is effective
         prior to the Repurchase Date, 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, such registration is effective or such approval is obtained
         prior to the Repurchase Date (it being understood that, in the case of
         this clause (ii) only, if (with respect to any particular Holder) (x)
         the Company has been unable so to effect such registration or obtain
         such approval after having used its reasonable best efforts to do so
         and, as a result, such Holder would be unable to receive shares of
         Common Stock or would receive shares of Common Stock that are not free
         from restrictions on transfer and (y) the Company pays the full amount
         of the Repurchase Price to such Holder in cash as provided in Section
         11.01, the condition set forth in this clause (ii) will be deemed to be
         satisfied);

                  (3) the Common Stock is listed, or shall have been, approved
         for listing on the New York Stock Exchange or another national
         securities exchange, or approved for quotation on the Nasdaq
         National Market, in any such case, prior to the Repurchase Date; and

                  (4) all shares of Common Stock which may be issued upon
         repurchase of Notes are issued out of the Company's authorized but
         unissued Common Stock (including treasury stock) and, upon issuance,
         will be duly and validly issued and fully paid and non-assessable and
         free of any preemptive or similar rights.

                                       65
<Page>

         If all of the conditions set forth in this Section 11.02 are not
satisfied in accordance with the terms thereof, the Repurchase Price shall be
paid by the Company only in cash.

         Section 11.03 NOTICES; METHOD OF EXERCISING REPURCHASE RIGHT, ETC.

                  (1) Within 30 days following any Change of Control, the
         Company shall mail a notice to each Holder (with a copy to the Trustee)
         describing the transaction or transactions that constitute the Change

                  places where, or procedures by which, such Notes are to be
                  surrendered for payment of the Repurchase Price and accrued
                  interest, if any, to the Repurchase Date;

                           (v) that on the Repurchase Date the Repurchase Price,
                  and accrued interest, if any, to the Repurchase Date, will
                  become due and payable upon each such Note designated by the
                  Holder to be repurchased, and that interest thereon shall

                  Repurchase Date, a telegram, telex,

                                       66
<Page>

                  facsimile transmission or letter setting forth the name of the
                  Holder, the principal amount of Notes delivered for purchase,
                  and a statement that such Holder is withdrawing his election
                  to have the Notes purchased; and

                           (x) that Holders whose Notes are being purchased only
                  in part shall be issued new Notes equal in principal amount to
                  the unpurchased portion of the Notes surrendered, which
                  unpurchased portion must be equal to U.S. $1,000 in principal
                  amount or an integral multiple thereof.

         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 Notes.

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

                  (2) To exercise a repurchase right, a Holder shall deliver to
         the Trustee on or before the date specified in the repurchase notice
         (i) written notice of the Holder's exercise of such right, which notice
         shall set forth the name of the Holder, the principal amount of the
         Notes to be repurchased (and, if any Note is to repurchased in part,
         the serial number thereof, the portion of the principal amount thereof
         to be repurchased 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 is being made thereby, and, in the event that the Repurchase
         Price 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) the Notes with respect to which
         the repurchase right is being exercised. The right of the Holder to
         convert the Notes with respect to which the repurchase right is being
         exercised shall continue until the close of business on the Business
         Day prior to the Repurchase Date.

                  (3) In the event a repurchase right shall be exercised in
         accordance with the terms hereof, on the Repurchase Date, the Company
         shall accept for payment all Notes or portions thereof properly
         tendered pursuant to the Change of Control Offer, deposit with or pay
         or cause to be paid to the Trustee the Repurchase Price in cash or
         shares of Common Stock, as provided above, for payment by the Trustee
         to the Holder on the Repurchase Date or, if shares of Common Stock are
         to be paid, as promptly after the Repurchase Date as practicable;
         provided, however, that installments of interest with a Stated Maturity
         on or prior to the Repurchase Date shall be payable in cash to the
         Holders of such Notes, or one or more Predecessor Notes, registered as
         such at the close of business on the relevant Regular Record Date; and
         deliver or cause to be delivered to the Trustee the Notes so accepted
         together with an Officers'

                                       67
<Page>

         Certificate stating the aggregate principal amount of Notes or portions
         thereof being purchased by the Company.

                  (4) If any Note (or portion thereof) surrendered for
         repurchase shall not be so paid on the Repurchase Date, the principal
         amount of such Note (or portion thereof, as the case may be) shall,
         until paid, bear interest to the extent permitted by applicable law
         from the Repurchase Date at the rate specified therein, and each Note
         shall remain convertible into Common Stock until the principal of such
         Note (or portion thereof, as the case may be) shall have been paid or
         duly provided for.

                  (5) Any Note which 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 mail (or
         cause to be transferred by book entry) to the Holder without service
         charge, a new Note or Notes, 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 Note so surrendered; provided that each such new Note shall be in
         principal amount of U.S. $1,000 or an integral multiple thereof.

                  (6) Any issuance of shares of Common Stock in respect of the
         Repurchase Price shall be deemed to have been effected immediately
         prior to the close of business on the Repurchase Date 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 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 Note declared prior to the Repurchase Date.

                  (7) No fractions of shares shall be issued upon repurchase of
         Notes. If more than one Note shall be repurchased from the same Holder
         and the Repurchase Price shall be payable in shares of Common Stock,
         the number of full shares which shall be issuable upon such repurchase
         shall be computed on the basis of the aggregate principal amount of the
         Notes so repurchased. Instead of

                                       68
<Page>

         any fractional share of Common Stock which would otherwise be issuable
         on the repurchase of any Note or Notes, the Company shall calculate and
         pay a cash adjustment in respect of such fraction (calculated to the
         nearest 1/100th of a share) or round up the number of shares of Common
         Stock issuable upon conversion to the nearest whole 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 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.

                  (8) Any issuance and delivery of certificates for shares of
         Common Stock on repurchase of Notes shall be made without charge to the
         Holder being repurchased for such certificates or for any tax or duty
         in respect of the issuance or delivery of such certificates or the
         Notes represented thereby; provided, however, that the Company shall
         not be required to pay any tax or duty which 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 Notes 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.

                  (9) All Notes 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 2.12.

         Notwithstanding any other provision of this Article 11, the Company
shall not be required to make a Change of Control Offer upon a Change of Control
if a third party makes the Change of Control Offer in the manner, at the times
and otherwise in compliance with the requirements set forth in this Indenture
applicable to a Change of Control Offer made by the Company and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.

         Section 11.04 CONSOLIDATION, MERGER, ETC. In the case of any merger,
consolidation, conveyance, sale, transfer or lease of all or substantially all
of the assets of the Company to which Section 10.11 applies, in which the Common
Stock of the Company is changed or exchanged as a result into the right to
receive shares of stock and other Notes or property or assets (including cash)
which includes shares of Common Stock or common stock of another Person that
are, or upon issuance will be, traded on a United States national securities
exchange or approved for trading on an established automated over-the-counter
trading market in the United States and such shares of

                                       69
<Page>

common stock of such Person constitute at the time such change or exchange
becomes effective in excess of 50% of the aggregate fair market value of such
shares of common stock of such Person and other securities, property and assets
(including cash) (as determined by the Company, which determination shall be
conclusive and binding), then the Person formed by such consolidation or
resulting from such merger or combination or which acquires the properties or
assets (including cash) of the Company, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture (which shall comply with the
Trust Indenture Act as in force at the date of execution of such supplemental
indenture) modifying the provisions of this Indenture relating to the right of
Holders to cause the Company to repurchase the Notes following a Change of
Control, including without limitation the applicable provisions of this Article
11 and the definitions of the Common Stock and Change of Control, as
appropriate, and such other related definitions set forth herein as determined
in good faith by the Company (which determination shall be conclusive and
binding), to make such provisions apply in the event of a subsequent Change of
Control to the common stock and the issuer thereof if different from the Company
and Common Stock of the Company (in lieu of the Company and the Common Stock of
the Company).

                           above, has deposited or caused to be deposited with
                           the Trustee as trust funds an amount sufficient to
                           pay and discharge the entire indebtedness on such
                           Notes not theretofore delivered to the Trustee for
                           cancellation, for principal and premium, if any
                           (including the Make-Whole Payment, if any), and
                           interest to the date of such deposit (in the case of
                           Notes which have become due and payable) or to the
                           maturity or redemption thereof, as the case may be;

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

                                       74
<Page>

                           (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
pursuant to this Article 13, the obligations of the Company to the Trustee under
Section 7.07, and, if money shall have been deposited with the Trustee pursuant
to subclause (B) of clause (1) of this Section, the obligations of the Trustee
under Section 13.02 and the obligations of the Company and the Trustee under
Section 2.07 and Article 10 shall survive such satisfaction and discharge. Funds
held in trust pursuant to this Section are not subject to the provisions of
Article 14.

         Section 13.02 APPLICATION OF TRUST MONEY. All money deposited with the
Trustee pursuant to Section 13.01 and in accordance with the provisions of
Article 14 shall be held in trust for the sole benefit of the Holders and not be
subject to the subordination provisions of Article 14, and such money shall be
applied by the Trustee, in accordance with the provisions of the Notes and this
Indenture, to the payment, either directly or through any Paying Agent as the
Trustee may determine, to the Persons entitled thereto, of the principal and
premium, if any (including the Make-Whole Payment, if any), and interest for
whose payment such money has been deposited with the Trustee.

         All moneys deposited with the Trustee pursuant to Section 13.01 (and
held by it or any Paying Agent) for the payment of Notes subsequently converted
shall be returned to the Company upon a written request signed in the name of
the Company by an Officer.

                                   ARTICLE 14

                             SUBORDINATION OF NOTES

         Section 14.01 NOTES SUBORDINATE TO SENIOR DEBT. The Company covenants
and agrees, and each Holder, by its acceptance thereof, likewise covenants and
agrees, that, to the extent and in the manner hereinafter set forth in this
Article (subject to the provisions of Article 13), the indebtedness represented
by the Notes and the payment of the principal of, or premium, if any (including
the Make-Whole Payment, if any), or interest on, each and all of the Notes
(including, but not limited to, the Redemption Price with respect to the Notes
to be called for redemption in accordance with Article 3 or the Repurchase Price
with respect to Notes submitted for repurchase in accordance with Article 11),
are hereby expressly made subordinate and subject in right of payment to the
prior payment in full of all Senior Debt.

                                       75
<Page>

         Section 14.02 NO PAYMENT IN CERTAIN CIRCUMSTANCES, PAYMENT OVER OF
PROCEEDS UPON DISSOLUTION, ETC. No payment shall be made with respect to the
principal of, or premium, if any (including the Make-Whole Payment, if any), or
interest on the Notes (including, but not limited to, the Redemption Price with
respect to the Notes to be called for redemption in accordance with Article 3 or
the Repurchase Price with respect to Notes submitted for repurchase in
accordance with Article 11), except payments and distributions made by the
Trustee as permitted by Section 14.09, if: (i) a default in the payment of
principal, premium, if any, or interest (including a default under any
repurchase or redemption obligation) or other amounts with respect to any Senior
Debt occurs and is continuing (or, in the case of Senior Debt for which there is
a period of grace, in the event of such a default that continues beyond the
period of grace, if any, specified in the instrument or lease evidencing such
Senior Debt) unless and until such default shall have been cured or waived or
shall have ceased to exist; or (ii) any other default occurs and is continuing
with respect to Designated Senior Debt and (1) the default permits holders of
such Designated Senior Debt to accelerate its maturity and (2) the Trustee
receives a notice of the default (a "Payment Blockage Notice") from a
Representative or holder of Designated Senior Debt or the Company.

         If the Trustee receives any Payment Blockage Notice pursuant to
clause (ii) above, no subsequent Payment Blockage Notice shall be effective
for purposes of this Section unless and until (A) at least 365 days shall
have elapsed since the initial effectiveness of the immediately prior Payment
Blockage Notice, and (B) all scheduled payments of principal, premium, if any
(including the Make-Whole Payment, if any), and interest on the Notes that
have come due have been paid in full. No default, other than a payment
default, that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

         The Company may and shall resume payments on and distributions in
respect of the Notes upon the earlier of:

                  (1) in the case of a default referred to in clause (i) above,
         the date upon which the default is cured or waived or ceases to exist,
         or

                  (2) in the case of a default referred to in clause (ii) above,
         the date upon which the default is cured or waived or ceases to exist
         or 179 days pass after notice is received if the maturity of such
         Designated Senior Debt has not been accelerated, unless this Article 14
         otherwise prohibits the payment or distribution at the time of such
         payment or distribution.

         In the event of (a) any acceleration of the principal amount due on the
Notes, (b) any insolvency or bankruptcy case or proceeding, or any receivership,
liquidation, reorganization or other similar case or proceeding in connection
therewith, relative to the

                                       76
<Page>

Company or to its creditors, as such, or to its assets, or (b) any
liquidation, dissolution or other winding up of the Company, whether
voluntary or involuntary and whether or not involving insolvency, bankruptcy,
receivership or other proceedings, or (c) any assignment for the benefit of
creditors or any other marshaling of assets and liabilities of the Company,
then and in any such event the holders of Senior Debt shall be entitled to
receive payment in full of all amounts due or to become due on or in respect
of all Senior Debt before the Holders are entitled to receive any payment on
account of principal of or premium, if any (including the Make-Whole Payment,
if any), or interest on the Notes or on account of the purchase, redemption
or other acquisition of Notes, and to that end the holders of Senior Debt
shall be entitled to receive, for application to the payment thereof, any
payment or distribution of any kind or character, whether in cash, property
or securities, which may be payable or deliverable in respect of the Notes in
any such case, proceeding, dissolution, liquidation or other winding up or
event.

         In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or a Holder shall have received any payment or distribution
of assets of the Company of any kind or character, whether in cash, securities
or other property, before all Senior Debt is paid in full, and if such fact
shall, at or prior to the time of such payment or distribution, have been made
known to the Trustee or, as the case may be, such Holder, then and in such event
such payment or distribution shall be paid over or delivered forthwith to the
trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent
or other Person making payment or distribution of assets of the Company for
application to the payment of all Senior Debt remaining unpaid, to the extent
necessary to pay all Senior Debt in full, after giving effect to any concurrent
payment or distribution to or for the holders of Senior Debt. For purposes of
this Article only, the words "cash, securities or other property" shall not be
deemed to include shares of capital stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment, which shares of stock or securities
are subordinated in right of payment to all then outstanding Senior Debt to
substantially the same extent as, or to a greater extent than, the Notes are so
subordinated as provided in this Article. The consolidation of the Company with,
or the merger of the Company into, another Person or the liquidation or
dissolution of the Company following the conveyance or transfer of its
properties and assets substantially as an entirety to another Person upon the
terms and conditions set forth in Article 5 shall not be deemed a dissolution,
winding up, liquidation, reorganization, assignment for the benefit of creditors
or marshaling of assets and liabilities of the Company for the purposes of this
Section if the Person formed by such consolidation or into which the Company is
merged or which acquires by conveyance or transfer such properties and assets
substantially as an entirety, as the case may be, shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions set
forth in Article 5.

         Section 14.03 PRIOR PAYMENT TO SENIOR DEBT UPON ACCELERATION OF NOTES.
In the event of the acceleration of the Notes because of an Event of Default, no
payment or distribution shall be made to the Trustee or any Holder in respect of
the principal of, premium, if any (including the Make-Whole Premium, if any), or
interest on the Notes (including, but not limited to, the Redemption Price with
respect to the Notes called for redemption in accordance with Article 3 or the
Repurchase Price with respect to the Notes submitted for repurchase in
accordance with Article 11), except payments and distributions made by the
Trustee as permitted by Section 14.09, until all Senior Debt has been paid in
full in cash or other payment satisfactory to the holders of Senior Debt or such
acceleration is rescinded in accordance with the terms of this Indenture. If
payment of the Notes is accelerated because of an Event of Default, the Company
shall promptly notify holders of Senior Debt of the acceleration.

         Section 14.04 PAYMENT PERMITTED IF NO DEFAULT. Nothing contained in
this Article or elsewhere in this Indenture or in any of the Notes shall prevent
(a) the Company, at any time except during the pendency of any case, proceeding,
dissolution, liquidation or other winding up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of the Company referred
to in Section 14.02, or during the circumstances referred to in the first
paragraph of Section 14.02, or under the conditions described in Section 14.03,
from making payments at any time of principal of and premium, if any (including
the Make-Whole Payment, if any), or interest on the Notes, or (b) the
application by the Trustee of any money deposited with it hereunder to the
payment of or on account of the principal of and premium, if any (including the
Make-Whole Payment, if any), or interest on the Notes or the retention of such
payment by the Holders, if, at the time of such application by the Trustee, it
did not have knowledge that such payment would have been prohibited by the
provisions of this Article.

         Section 14.05 SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR DEBT. Subject
to the payment in full of all Senior Debt, the Holders of the Notes shall be
subrogated to the extent of the payments or distributions made to the holders of
such Senior Debt pursuant to the provisions of this Article to the rights of the
holders of such Senior Debt to receive payments and distributions of cash,
property and securities applicable to the Senior Debt until the principal of and
premium, if any (including the Make-Whole Payment, if any), and interest on the
Notes shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Senior Debt of any cash, property or
securities to which the Holders or the Trustee would be entitled except for the
provisions of this Article, and no payments made pursuant to the provisions of
this Article to the holders of Senior Debt by Holders or the Trustee, shall, as
among the Company, its creditors other than holders of Senior Debt and the
Holders, be deemed to be a payment or distribution by the Company to or on
account of the Senior Debt.

                                       78
<Page>

         Section 14.06 PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS. The
provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the Holders on the one hand and the holders of
Senior Debt on the other hand. Nothing contained in this Article or elsewhere in
this Indenture or in the Notes is intended to or shall (i) impair, as among the
Company, its creditors other than holders of Senior Debt and the Holders of the
Notes, the obligation of the Company, which is absolute and unconditional, to
pay to the Holders of the Notes the principal of and premium, if any (including
the Make-Whole Payment, if any), and interest on the Notes as and when the same
shall become due and payable in accordance with their terms; or (ii) affect the
relative rights against the Company of the Holders and other creditors of the
Company (other than the holders of Senior Debt); or (iii) prevent the Trustee or
any Holder from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article of the holders of Senior Debt to receive cash, property and securities
otherwise payable or deliverable to the Trustee or such Holder.

         Section 14.07 TRUSTEE TO EFFECTUATE SUBORDINATION. Each Holder by its
acceptance thereof authorizes and directs the Trustee on its behalf to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this Article and appoints the Trustee its attorney-in-fact for any
and all such purposes.

         Section 14.08 NO WAIVER OF SUBORDINATION PROVISIONS. No right of any
present or future holder of any Senior Debt to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company, or by any non-compliance by the
Company with the terms, provisions and covenants of this Indenture, regardless
of any knowledge thereof any such holder may have or be otherwise charged with.
Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders, without incurring
responsibility to the Holders and without impairing or releasing the
subordination provided in this Article or the obligations hereunder of the
Holders to the holders of Senior Debt, do any one or more of the following: (i)
change the manner, place or terms of payment or extend the time of payment of,
or renew or alter, Senior Debt, or otherwise amend or supplement in any manner
Senior Debt or any instrument evidencing the same or any agreement under which
Senior Debt is outstanding; (ii) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing Senior Debt; (iii) release
any Person liable in any manner for the collection of Senior Debt; and (iv)
exercise or refrain from exercising any rights against the Company and any other
Person.

         Section 14.09 NOTICE TO TRUSTEE. The Company shall give prompt written
notice to the Trustee of any fact known to the Company which would prohibit the
making of any payment to or by the Trustee in respect of the Notes.
Notwithstanding the provisions of

                                       79
<Page>

this Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Notes, unless and
until a Responsible Officer of the Trustee shall have received written notice
thereof from the Company or a Representative or a holder of Senior Debt
(including, without limitation, a holder of Designated Senior Debt) and, prior
to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 7.01, shall be entitled in all respects to assume that no
such facts exist; provided, however, that if the Trustee shall not have received
the notice provided for in this Section 14.09 at least two Business Days prior
to the date upon which by the terms hereof any money may become payable for any
purpose (including, without limitation, the payment of the principal of and
premium, if any (including the Make-Whole Payment, if any), or interest on any
Note), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such money and to apply
the same to the purpose for which such money was received and shall not be
affected by any notice to the contrary which may be received by it within one
Business Day prior to such date.

         Notwithstanding anything in this Article 14 to the contrary, nothing
shall prevent any payment by the Trustee to the Holders of monies deposited with
it pursuant to Section 13.01, and any such payment shall not be subject to the
provisions of Section 14.02 or 14.03.

         Subject to the provisions of Section 7.01, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a Representative or a holder of Senior Debt
(including, without limitation, a holder of Designated Senior Debt) to establish
that such notice has been given by a Representative or a holder of Senior Debt
(including, without limitation, a holder of Designated Senior Debt). In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior Debt to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such Person to furnish evidence to the reasonable satisfaction of
the Trustee as to the amount of Senior Debt held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such Person under this Article, and
if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

         Section 14.10 RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
AGENT. Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 7.01, and the
Holders shall be entitled to rely upon any order or decree entered by any court
of competent jurisdiction in which such insolvency, bankruptcy, receivership,
liquidation, reorganization, dissolution, winding up or similar case or
proceeding is pending, or a certificate of the trustee in bankruptcy,

                                       80
<Page>

receiver, liquidating trustee, custodian, assignee for the benefit of creditors,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders, for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of the Senior Debt
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.

         Section 14.11 TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR DEBT. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Debt and shall not be liable to any such holders if it shall in good faith
mistakenly pay over or distribute to Holders or to the Company or to any other
Person cash, property or securities to which any holders of Senior Debt shall be
entitled by virtue of this Article or otherwise.

         Section 14.12 RELIANCE BY HOLDERS OF SENIOR DEBT ON SUBORDINATION
PROVISIONS. Each Holder by accepting a Note acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to each holder of any Senior Debt, whether such Senior Debt
was created or acquired before or after the issuance of the Notes, to acquire
and continue to hold, or to continue to hold, such Senior Debt and such holder
of Senior Debt shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Debt, and no amendment or modification of the provisions contained herein
shall diminish the rights of such holders of Senior Debt unless such holders
shall have agreed in writing thereto.

         Section 14.13 RIGHTS OF TRUSTEE AS HOLDER OF SENIOR DEBT; PRESERVATION
OF TRUSTEE'S RIGHTS. The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article with respect to any Senior Debt which
may at any time be held by it, to the same extent as any other holder of Senior
Debt, and nothing in this Indenture shall deprive the Trustee of any of its
rights as such holder. Nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 7.07.

         Section 14.14 ARTICLE APPLICABLE TO PAYING AGENTS. In case at any time
any Paying Agent other than the Trustee shall have been appointed by the Company
and be then acting hereunder, the term "Trustee" as used in this Article shall
in such case (unless the context otherwise requires) be construed as extending
to and including such Paying Agent within its meaning as fully for all intents
and purposes as if such Paying Agent were named in this Article in addition to
or in place of the Trustee; provided, however, that Section 14.14 shall not
apply to the Company or any Affiliate of the Company if it or such Affiliate
acts as Paying Agent.

         Section 14.15 CERTAIN CONVERSIONS AND REPURCHASES DEEMED PAYMENT. For
the purposes of this Article only, (i) the issuance and delivery of junior
securities upon conversion of Notes in accordance with Article 10 or upon the
repurchase of Notes in

                                       81
<Page>

accordance with Article 11 shall not be deemed to constitute a payment or
distribution on account of the principal of or premium or interest on Notes
or on account of the purchase or other acquisition of Notes, and (ii) the
payment, issuance or delivery of cash (except in satisfaction of fractional
shares pursuant to Section 3.06(c), 10.03 or 11.03(7)), property or
securities (other than junior securities) upon conversion of a Note shall be
deemed to constitute payment on account of the principal of such Note. For
the purposes of this Section, the term "junior securities" means (a) shares
of any stock of any class of the Company and other securities into which the
Notes are convertible pursuant to Article 10 and (b) securities of the
Company which are subordinated in right of payment to all Senior Debt which
may be outstanding at the time of issuance or delivery of such securities to
substantially the same extent as, or to a greater extent than, the Notes are
so subordinated as provided in this Article. Nothing contained in this
Article or elsewhere in this Indenture or in the Notes is intended to or
shall impair, as among the Company, its creditors other than holders of
Senior Debt and the Holders of the Notes, the right, which is absolute and
unconditional, of any Holder to convert any Note in accordance with Article
10 or to exchange such Note for Common Stock in accordance with Article 11 if
the Company elects to satisfy the obligations under Article 11 by the
delivery of Common Stock.

                                 [BACK OF NOTE]

                [_____]% Convertible Subordinated Notes due 2008

         Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

         1. INTEREST. Community Health Systems, Inc., a Delaware corporation (as
further defined in the Indenture, the "Company"), promises to pay interest on
the principal amount of this Note at the rate of [_____]% per annum from
[________], [_____] until Maturity. The Company will pay interest semi-annually
in arrears on [_____________] and [_____________] of each year (each an
"Interest Payment Date"), or if any such day is not a Business Day, on the next
succeeding Business Day. Interest on the Notes will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from the
Issue Date; provided that if there is no existing Default in the payment of
interest, and if this Note is authenticated between a Regular Record Date
referred to on the face and the next succeeding Interest Payment Date, interest
shall accrue from such next succeeding Interest Payment Date. The first Interest
Payment Date shall be [_____________], [_____]. The Company shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal and premium, if any (including the Make-Whole Payment, if
any), from time to time on demand at a rate that is 1% per annum in excess of
the rate then in effect; and it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

         2. METHOD OF PAYMENT. The Company shall pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders at the
close of business on the [_____________] or [_____________] next preceding the
Interest Payment Date, even if such Notes are canceled after such record date
and on or before such Interest Payment Date, except as provided in Section 2.13
of the Indenture with respect to defaulted interest. The Notes will be payable
as to principal, premium, if any (including the Make-Whole Payment, if any), and
interest at the office or agency of the Company maintained for such purpose
within or without the City and State of New York, or, at the option of the
Company, payment of interest may be made by check mailed to the Holders at their
addresses set forth in the Note Register, and provided that payment by wire
transfer of immediately available funds will be required with respect to
principal of and interest and premium on all Global Notes and all other Notes
the Holders of which shall have provided wire transfer instructions to the
Company or the Paying Agent. Such payment shall be in such coin or currency of
the United States of America as at the time of payment is legal tender for
payment of public and private debts.

                                      A-4
<Page>

         3. PAYING AGENT, REGISTRAR AND CONVERSION AGENT. Initially, First Union
National Bank, the Trustee under the Indenture, will act as Paying Agent,
Registrar and Conversion Agent. The Company may change any Paying Agent,
Registrar or Conversion Agent without notice to any Holder. The Company or any
of its Subsidiaries may act in any such capacity.

         4. INDENTURE. The Company issued the Notes under an Indenture dated as
of October, [_____] (the "Indenture") between the Company and the Trustee. The
terms of the Notes include those stated in the Indenture and those made part of
the Indenture by reference to the TIA. The Notes are subject to all such terms,
and Holders are referred to the Indenture and the TIA Act for a statement of
such terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. The Notes are obligations of the Company limited to $250,000,000
million in principal amount (or up to $287,000,000 to the extent the
Underwriters exercise their over-allotment option pursuant to the Underwriting
Agreement) except as provided in Section 2.08 of the Indenture.

         5. PROVISIONAL REDEMPTION. Prior to [____], 2005, if the Closing Price
of the Common Stock shall have exceeded 150% of the Conversion Price then in
effect for at least 20 Trading Days in any consecutive 30-day Trading Day
period ending on the Trading Day prior to the date mailing of the notice of
Provisional Redemption pursuant to Section 3.03 of the Indenture (the "Notice
Date"), the Company may redeem the Notes ("Provisional Redemption"), in whole
or from time to time in part, upon not more than 30 nor more than 60 days'
notice prior to the Redemption Date, at a Redemption Price equal to the
principal amount of the Notes to be redeemed plus accrued and unpaid
interest, if any, to the Redemption Date. Upon any such Provisional
Redemption, the Company shall make an additional payment (the "Make-Whole
Payment") in cash or, at the election of the Company upon satisfaction of the
conditions in Section 3.12 of the Indenture, in Common Stock or a combination
of cash and Common Stock, as specified in the notice of redemption, with
respect to the Notes called for redemption to holders on the Notice Date in
an amount equal to $[__] per $1,000 aggregate principal amount of Notes, less
the amount of any interest actually paid or accrued and unpaid since the
Issue Date on each $1,000 aggregate principal amount of Notes so redeemed
(including any Predecessor Notes) prior to the Redemption Date. The Company
shall make the Make-Whole Payment on all Notes called for Provisional
Redemption, including any Notes converted into Common Stock pursuant to the
terms of this Indenture after the Notice Date and prior to the Redemption
Date. For purposes of this paragraph, the payments made in Common Stock will
be determined by the Company and each share of Common Stock to be delivered
shall be valued at an amount equal to 95% of the average of the Closing Price
Per Share of the Common Stock for the five consecutive Trading Days
immediately preceding and including the third Trading Day prior to the
Redemption Date.

                                      A-5

         6. OPTIONAL REDEMPTION. Except as provided in paragraph (5) herein, the
Company shall not have the option to redeem the Notes prior to [_____________],
2005. On or after [_____], 2005, the Company may redeem the Notes, in whole or
in part, in cash upon not less than 30 nor more than 60 days' notice, at the
Redemption Prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest thereon, if any, to the applicable Redemption
Date, if redeemed during the twelve-month period beginning on [______] of the
years indicated below:

                              YEAR                   PERCENTAGE
                              ----                   ----------

                            [______], 2005             [______]%
                            [______], 2006             [______]%

and thereafter is equal to 100% of the principal amount, in each case together
with accrued but unpaid interest to the applicable Redemption Date.

         7. NOTICE OF REDEMPTION. Notice of redemption will be mailed by first
class mail at least 30 days but not more than 60 days before the Redemption Date
to each Holder whose Notes are to be redeemed at its registered address. Notices
of redemption may not be conditional. No Notes of U.S. $1,000 or less may be
redeemed in part. Notes in denominations larger than U.S. $1,000 may be redeemed
in part but only in whole multiples of U.S. $1,000, unless all of the Notes held
by a Holder are to be redeemed. On and after the Redemption Date, interest
ceases to accrue on Notes or portions thereof called for redemption.

         8. MANDATORY REDEMPTION. Except as otherwise provided in Paragraph 8
below, the Company shall not be required to make mandatory redemption payments
with respect to the Notes.

         9. REPURCHASE AT OPTION OF HOLDER. If a Change of Control occurs, the
Company shall make a Change of Control Offer to repurchase all or any part
(equal to U.S. $1,000 or an integral multiple thereof) of each Holder's Notes at
a purchase price equal to 100% of the principal amount thereof plus interest
accrued and unpaid to the date of purchase. At the option of the Company, the
Repurchase Price may be paid in cash or, subject to the provisions of the
Indenture, by delivery of shares of Common Stock having a fair market value
equal to the Repurchase Price. For purposes of this paragraph, the fair market
value of shares of Common Stock 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 fifth Trading Day prior to the Repurchase Date as
determined by the Company. Except as otherwise provided in the Indenture, within
30 days following any Change of Control, the Company shall mail a notice to each
Holder describing the transaction or transactions that constitute the Change of
Control and

                                      A-6
<Page>

offering to repurchase Notes on the Repurchase Date specified in such notice,
pursuant to the procedures required by the Indenture and described in such
notice.

         10. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of U.S. $1,000 and integral multiples of U.S.
$1,000. The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and the Company may require a Holder to pay any taxes and fees required by law
or permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Company
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a
Regular Record Date and the corresponding Interest Payment Date.

         11. PERSONS DEEMED OWNERS. The registered Holder may be treated as its
owner for all purposes.

         12. AMENDMENT AND SUPPLEMENT. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with either (i) the
written consent (or as otherwise in accordance with the Applicable Procedures)
of the Holders of at least a majority in aggregate principal amount of the Notes
then outstanding (including, without limitation, consents obtained in connection
with a purchase of, or tender offer or exchange offer for, Notes), or (ii) by
the adoption of a resolution, at a meeting of Holders of the then outstanding
Notes at which a quorum is present, by the Holders of at least 66?% in principal
amount of the then outstanding Notes represented at such meeting or, if less, by
the Holders of at least a majority in aggregate principal amount of all then
outstanding Notes. Without the consent of any Holder, the Company and the
Trustee may amend or supplement the Indenture or the Notes to cure any
ambiguity, defect or inconsistency, to provide for uncertificated Notes in
addition to or in place of certificated Notes, to provide for the assumption of
the Company's obligations to Holders in the case of a merger or consolidation or
sale of all or substantially all of the assets of the Company, to make any
change that would provide any additional rights or benefits to the Holders or
that does not adversely affect the legal rights under the Indenture of any such
Holder, or to comply with the requirements of the Commission in order to effect
or maintain the qualification of the Indenture under the TIA or otherwise as
necessary to comply with applicable law.

         13. SUBORDINATION. The Indebtedness evidenced by this Note is, to the
extent and in the manner provided in the Indenture, subordinate and subject in
right of payment to the prior payment in full of all Senior Debt of the Company,
and this Note is issued subject to such provisions of the Indenture with respect
thereto. Each Holder of this Note, by accepting the same, (a) agrees to and
shall be bound by such provisions,

                                      A-7
<Page>

(b) authorizes and directs the Trustee on his behalf to take such action as may
be necessary or appropriate to effectuate the subordination so provided and (c)
appoints the Trustee his attorney-in-fact for any and all such purposes.

         14. DEFAULTS AND REMEDIES. Each of the following is an Event of
Default: (i) default for 30 days in the payment when due of interest on the
Notes, whether or not such payment is prohibited by the subordination provisions
of the Notes or of the Indenture, (ii) default in payment when due of the
principal of or premium, if any (including the Make-Whole Payment, if any), on
the Notes, whether or not such payment is prohibited by the subordination
provisions of the Notes or of the Indenture, (iii) failure by the Company to
comply with the notice or repurchase provisions of Article 11 of the Indenture,
whether or not the compliance with such notice or repurchase provision is
prohibited by the subordination provisions of the Notes or the Indenture, (iv)
failure by the Company to deliver shares of Common Stock or cash instead of
fractional shares, when those shares of Common stock or cash instead of
fractional shares are required to be delivered following conversion of a Note
pursuant to the provisions of Article 10 of the Indenture and that failure
continues for 10 days, (v) failure by the Company for 60 days after written
notice thereof has been given to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% of the aggregate principal amount
of the Notes then outstanding to comply with any of its other covenants or
agreements in the Indenture, (vi) default under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the Company or any of its
Significant Subsidiaries (or the payment of which is guaranteed by the Company
or any of its Significant Subsidiaries), whether such Indebtedness or guarantee
now exists or is created after the Issue Date, if that default: (a) is caused by
a failure to pay at final stated maturity the principal amount of such
Indebtedness at the end of the applicable expiration of the grace period
provided in such Indebtedness on the date of such default (a "Payment Default");
or (b) results in the acceleration of such Indebtedness prior to its express
maturity, and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness under which
there has been a Payment Default or the maturity of which has been so
accelerated, aggregates $15 million or more, and (1) the indebtedness is not
discharged, or the acceleration is not annulled, within 30 days after written
notice of such Event of Default to the Company by the Trustee or (2) the holders
of at least 25% in aggregate principal amount of the then outstanding Notes, or
(vii) certain events of bankruptcy or insolvency with respect to the Company or
any of its Significant Subsidiaries. In the case of an Event of Default arising
from certain events of bankruptcy or insolvency with respect to the Company, all
then outstanding Notes will, subject to the provisions of Article 14 of the
Indenture, become due and payable without further action or notice. If any other
Event of Default occurs and is continuing, the Trustee by notice to the Company
or the Holders of at least 25% in principal amount of the then outstanding Notes
by notice to the Company and the Trustee may, subject to the provisions of
Article 14 of the Indenture, declare all the Notes to be due and payable

                                      A-8
<Page>

immediately. Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in aggregate principal amount of the then outstanding Notes may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders notice of any continuing Default or Event of Default (except a Default
or Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest. Holders, either (i)
through the written consent (or as otherwise in accordance with the Applicable
Procedures) of the Holders of at least a majority in aggregate principal amount
of the then outstanding Notes by notice to the Trustee or (ii) by the adoption
of a resolution, at a meeting of Holders of the then outstanding Notes at which
a quorum is present, by the Holders of at least 66?% in the principal amount of
then outstanding Notes represented at such meeting or, if less, by the Holders
of at least a majority in aggregate principal amount of all then outstanding
Notes by notice to the Trustee, may on behalf of the Holders of all of the Notes
waive any existing Default or Event of Default and its consequences under the
Indenture, except (x) a continuing Default or Event of Default in the payment of
the principal of, premium, if any (including the Make-Whole Payment, if any), or
interest on the Notes (including in connection with a Change of Control Offer),
(y) a continuing Default or Event of Default in respect of a Holder's right to
convert any Note in accordance with Article 10 of the Indenture or (z) or in
respect of a covenant or provision of the Indenture under Article 9 thereof
which cannot be modified or amended without the consent of each outstanding Note
affected. The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture. Upon becoming aware of any Default or
Event of Default, the Company is required to deliver to the Trustee a statement
specifying such Default or Event of Default.

         15. CONVERSION. Subject to and upon compliance with the provisions of
the Indenture, the Holder of this Note is entitled, at his option, at any time
on or before the close of business on the Business Day prior to the date of
Maturity, or in case this Note or a portion hereof is called for redemption or
the Holder hereof has exercised his right to require the Company to repurchase
this Note or such portion hereof, then in respect of this Note until and
including, 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 prior to the Redemption Date or the 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
[_____________] shares of Common Stock for each U.S. $1,000 principal amount of
Notes (or at the current adjusted Conversion Rate if an adjustment has been made
as provided in the Indenture) by surrender of this Note, duly endorsed or
assigned to the Company or in blank and, in case such surrender shall be made
during the Record Date Period (except if this Note or portion thereof has been
called for redemption on a Redemption Date occurring within such Record Date
Period and, as a result, the right to

                                      A-9
<Page>

convert would terminate in such period), also 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
this Note then being converted, and also the conversion notice hereon duly
executed, to the 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 may be designated by it pursuant to the
Indenture; provided, further, that if this Note or portion hereof has been
called for redemption on a Redemption Date occurring during the Record Date
Period, and is surrendered for conversion during such period, then the Holder of
this Note on the related 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 Note who converts this Note or a portion hereof during such period shall
not be required to pay such interest upon surrender of this Note for conversion.
Subject to the provisions of the preceding sentence, 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 Note is
convertible and such delivery will be deemed to satisfy the Company's obligation
to pay the principal amount of this Note. 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 (or round up
the number of shares of Common Stock issuable upon conversion to the nearest
whole share).

         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 outstanding shares of Common Stock) or
any 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, so that this Note, if then outstanding, will be
convertible thereafter, during the period this Note 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 into which this
Note 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

                                      A-10
<Page>

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.

         16. TRUSTEE DEALINGS WITH COMPANY. Except as set forth in the
Indenture, the Trustee, in its individual or any other capacity, may make loans
to, accept deposits from, and perform services for the Company or its
Affiliates, and may otherwise deal with the Company or its Affiliates, as if it
were not the Trustee.

         17. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

         18. GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL
GOVERN AND BE USED TO CONSTRUE THIS NOTE AND THE INDENTURE WITHOUT GIVING EFFECT
TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION
OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         19. AUTHENTICATION. This Note shall not be valid until authenticated by
the manual signature (which may be by facsimile) of the Trustee or an
authenticating agent.

         20. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TENENT (= tenants
by the entireties), JT TEN (= joint tenants with right of survivorship and not
as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to
Minors Act).

         21. CUSIP NUMBERS. No representation is made as to the accuracy of any
CUSIP numbers either as printed on the Notes or as contained in any notice of
redemption and reliance may be placed only on the other identification numbers
placed thereon.

         The undersigned Holder of this Note hereby irrevocably exercises the
option to convert this Note, or any portion of the principal amount hereof
