                                 THE SECURITIES

     Section 2.01  Form And Dating.

     The Securities and the Trustee's certificate of authentication shall be
substantially in the respective forms set forth in Exhibit A, which Exhibit is
incorporated in and made part of this Indenture. The Securities may have
notations, legends or endorsements required by law, stock exchange rule or
usage. The Company shall provide any such notations, legends or endorsements to
the Trustee in writing. Each Security shall be dated the date of its
authentication. The Securities are being offered and sold by the Company
pursuant to a Purchase Agreement dated February 25, 2004 (the "Purchase
Agreement") between the Company and the Initial Purchasers, in transactions
exempt from, or not subject to, the registration requirements of the Securities
Act.

     (a)  Restricted Global Securities. All of the Securities are initially
being offered and sold to qualified institutional buyers as defined in Rule 144A
(collectively, "QIBs" or individually, each a "QIB") in reliance on Rule 144A
under the Securities Act and shall be issued initially in the form of one or
more Restricted Global Securities, which shall be deposited on behalf of the
purchasers of the Securities represented thereby with the Trustee, at its
Corporate Trust Office, as custodian for the depositary, The Depository Trust
Company ("DTC", and such depositary, or any successor thereto, being hereinafter
referred to as the "Depositary"), and registered in the name of its nominee,
Cede & Co. (or any successor thereto), for the accounts of participants in the
Depositary, duly executed by the Company and authenticated by the Trustee as
hereinafter provided. The aggregate principal amount of the Restricted Global
Securities may from time to time be increased or decreased by adjustments made
on the records of the Securities Custodian as hereinafter provided, subject in
each case to compliance with the Applicable Procedures.

     (b)  Global Securities In General. Each Global Security shall represent
such of the outstanding Securities as shall be specified therein and each shall
provide that it shall represent the aggregate amount of outstanding Securities
from time to time endorsed thereon and that the aggregate amount of outstanding
Securities represented thereby may from time to time be reduced or increased, as

                                        9

<PAGE>

appropriate, to reflect replacements, exchanges, purchases, redemptions, or
conversions of such Securities. Any adjustment of the aggregate principal amount
of a Global Security to reflect the amount of any increase or decrease in the
amount of outstanding Securities represented thereby shall be made by the
Trustee in accordance with instructions given by the Holder thereof as required
by Section 2.12 hereof and shall be made on the records of the Trustee and the
Depositary.

     Members of, or participants in, the Depositary ("Agent Members") shall have
no rights under this Indenture with respect to any Global Security held on their
behalf by the Depositary or under the Global Security, and the Depositary
(including, for this purpose, its nominee) may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner and
Holder of such Global Security for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall (1) prevent the Company, the Trustee or any
agent of the Company or the Trustee from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or (2)
impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of any
Security.

     (c)  Book Entry Provisions. The Company shall execute and the Trustee
shall, in accordance with this Subsection 2.01(c), authenticate and deliver
initially one or more Global Securities that (1) shall be registered in the name
of the Depositary or its nominee, (2) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary's instructions and (3) shall bear
legends substantially to the following effect:

     "UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
     THE DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION
     OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED
     IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN
     AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT
     HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN
     AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER,
     PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
     WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
     HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE
     INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A
     DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR
     SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR
     ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE
     AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN
     DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY
     THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE
     DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE
     DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF
     SUCH SUCCESSOR DEPOSITARY."

     Section 2.02  Execution And Authentication.

     (a)  The aggregate Principal Amount at Maturity of Securities which may be
authenticated and delivered under this Indenture is limited to $348,000,000
except as provided in Sections 2.06 and 2.07.

                                       10

<PAGE>

     (b)  An Officer shall sign the Securities for the Company by manual or
facsimile signature. Typographic and other minor errors or defects in any such
facsimile signature shall not affect the validity or enforceability of any
Security which has been authenticated and delivered by the Trustee.

     (c)  If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

     (d)  A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

     (e)  The Trustee shall authenticate and make available for delivery
Securities for original issue in the aggregate Principal Amount at Maturity of
up to $348,000,000 upon receipt of a written order or orders of the Company
signed by an Officer of the Company (a "Company Order"). The Company Order shall
specify the amount of Securities to be authenticated, shall provide that all
such Securities will be represented by a Restricted Global Security and the date
on which each original issue of Securities is to be authenticated.

     (f)  The Trustee shall act as the initial authenticating agent. Thereafter,
the Trustee may appoint an authenticating agent acceptable to the Company to
authenticate Securities. An authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent shall have the same rights as an Agent to deal with the
Company or an Affiliate of the Company.

     (g)  The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 Principal Amount at Maturity and any
integral multiple thereof.

     Section 2.03  Registrar, Paying Agent, Conversion Agent and Bid
Solicitation Agent.

     (a)  The Company shall maintain one or more offices or agencies where
Securities may be presented for registration of transfer or for exchange (each,
a "Registrar"), one or more offices or agencies where Securities may be
presented for payment (each, a "Paying Agent"), one or more offices or agencies
where Securities may be presented for conversion (each, a "Conversion Agent")
and one or more offices or agencies where notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served. The
Company shall also appoint a bid solicitation agent (the "Bid Solicitation
Agent") to act pursuant to Article 4. The Company will at all times maintain a
Paying Agent, Conversion Agent, Bid Solicitation Agent, Registrar and an office
or agency where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served in the Borough of Manhattan, The
City of New York. One of the Registrars (the "Primary Registrar") shall keep a
register of the Securities and of their transfer and exchange.

     (b)  The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall notify
the Trustee of the name and address of any Agent not a party to this Indenture.
If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent,
Bid Solicitation Agent or agent for service of notices and demands in any place
required by this Indenture, or fails to give the foregoing notice, the Trustee
shall act as such. The Company or any Affiliate of the Company may act as Paying
Agent (except for the purposes of Section 6.01 and Article 10).

     (c)  The Company hereby initially designates the Trustee as Paying Agent,
Registrar, Custodian (as defined in Section 8.01), Conversion Agent and Bid
Solicitation Agent, and each of the

                                       11

<PAGE>

Corporate Trust Office of the Trustee and the office or agency of Wells Fargo
Bank, National Association, in the Borough of Manhattan, The City of New York,
one such office or agency of the Company for each of the aforesaid purposes.

     Section 2.04  Paying Agent To Hold Money In Trust.

     Prior to 11:00 a.m., New York City time, on each due date of the payment of
principal of, or interest on, any Securities, the Company shall deposit or, in
the case of the first six scheduled interest payments on the Securities, if the
Company so elects, cause to be deposited in accordance with the Pledge
Agreement, with a Paying Agent a sum sufficient to pay such principal or
interest so becoming due. Subject to Sections 10.02 and 13.05, a Paying Agent
shall hold in trust for the benefit of Securityholders or the Trustee all money
held by the Paying Agent for the payment of principal of, or interest on, the
Securities, and shall notify the Trustee of any default by the Company (or any
other obligor on the Securities) in making any such payment. If the Company or
an Affiliate of the Company acts as Paying Agent, it shall, before 11:00 a.m.,
New York City time, on each due date of the principal of, or interest on, any
Securities, segregate the money and hold it as a separate trust fund. The
Company at any time may require a Paying Agent to pay all money held by it to
the Trustee, and the Trustee may at any time during the continuance of any
default, upon written request to a Paying Agent, require such Paying Agent to
pay forthwith to the Trustee all sums so held in trust by such Paying Agent.
Upon doing so, the Paying Agent (other than the Company) shall have no further
liability for the money.

     Section 2.05  Securityholder 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
Securityholders. If the Trustee is not the Primary Registrar, the Company shall
furnish to the Trustee on or before each semiannual 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 Securityholders.

     Section 2.06  Transfer And Exchange.

     (a)  Subject to compliance with any applicable additional requirements
contained in Section 2.12, when a Security is presented to a Registrar with a
request to register a transfer thereof or to exchange such Security for an equal
principal amount of Securities of other authorized denominations, the Registrar
shall register the transfer or make the exchange as requested; provided,
however, that every Security presented or surrendered for registration of
transfer or exchange shall be duly endorsed or accompanied by an assignment form
and, if applicable, a transfer certificate each in the form included in Exhibit
A, and in form satisfactory to the Registrar duly executed by the Holder thereof
or its attorney duly authorized in writing. To permit registration of transfers
and exchanges, upon surrender of any Security for registration of transfer or
exchange at an office or agency maintained pursuant to Section 2.03, the Company
shall execute and the Trustee shall authenticate Securities of a like aggregate
Principal Amount at Maturity at the Registrar's request. Any exchange or
transfer shall be without charge, except that the Company or the Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto, and provided, that this sentence
shall not apply to any exchange pursuant to Section 2.10, 2.12(a), 3.06, 3.13,
4.02(e) or 11.05.

     (b)  Neither the Company, any Registrar nor the Trustee shall be
required to exchange or register a transfer of (1) any Securities for a period
of 15 days next preceding mailing of a notice of Securities to be redeemed, (2)
any Securities or portions thereof selected or called for redemption (except, in
the case of redemption of a Security in part, the portion thereof not to be
redeemed), (3) any Securities or portions thereof in respect of which a Change
in Control Purchase Notice has been delivered and not

                                       12

<PAGE>

withdrawn by the Holder thereof (except, in the case of the purchase of a
Security in part, the portion thereof not to be purchased) or (4) any Securities
or portions thereof in respect of which a Put Right Purchase Notice has been
delivered and not withdrawn by the Holder thereof (except, in the case of the
purchase of a Security in part, the portion thereof not to be purchased).

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

     (d)  Any Registrar appointed pursuant to Section 2.03 hereof shall provide
to the Trustee such information as the Trustee may reasonably require in
connection with the delivery by such Registrar of Securities upon transfer or
exchange of Securities.

     (e)  Each Holder of a Security agrees to indemnify the Company and the
Trustee against any liability that may result from the transfer, exchange or
assignment of such Holder's Security in violation of any provision of this
Indenture and/or applicable United States federal or state securities law.

     (f)  The Trustee shall have no obligation or duty to monitor,
determine or inquire as to compliance with any restrictions on transfer imposed
under this Indenture or under applicable law with respect to any transfer of any
interest in any Security (including any transfers between or among Agent Members
or other beneficial owners of interests in any Global Security) other than to
require delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by the terms
of, this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

     Section 2.07  Replacement Securities.

     (a)  If any mutilated Security is surrendered to the Company, a
Registrar or the Trustee, or the Company, a Registrar and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any
Security, and there is delivered to the Company, the applicable Registrar and
the Trustee such security or indemnity as will be required by them to save each
of them harmless, then, in the absence of notice to the Company, such Registrar
or the Trustee that such Security has been acquired by a bona fide purchaser,
the Company shall execute, and upon its written request the Trustee shall
authenticate and deliver, in exchange for any such mutilated Security or in lieu
of any such destroyed, lost or stolen Security, a new Security of like tenor and
Principal Amount at Maturity, bearing a number not contemporaneously
outstanding.

     (b)  In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, or is about to be purchased,
redeemed or by the Company pursuant to Article 3, the Company in its discretion
may, instead of issuing a new Security, pay, redeem, or purchase such Security,
as the case may be.

     (c)  Upon the issuance of any new Securities under this Section 2.07,
the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
reasonable expenses (including the reasonable fees and expenses of the Trustee
or the Registrar) in connection therewith.

     (d)  Every new Security issued pursuant to this Section 2.07 in lieu
of any mutilated, destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Company, whether or not the
mutilated, destroyed, lost or stolen Security shall be at any time enforceable

                                       13

<PAGE>

by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

     (e)  The provisions of this Section 2.07 are (to the extent lawful)
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities.

     Section 2.08  Outstanding Securities.

     (a)  Securities outstanding at any time are all Securities authenticated
by the Trustee, except for those canceled by it, those redeemed or purchased
pursuant to Article 3, those converted pursuant to Article 4, those delivered to
the Trustee for cancellation or surrendered for transfer or exchange and those
described in this Section 2.08 as not outstanding.

     (b)  If a Security is replaced pursuant to Section 2.07, it ceases to
be outstanding unless the Company receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

     (c)  If a Paying Agent (other than the Company or an Affiliate of the
Company) holds in respect of the outstanding Securities on a Redemption Date, a
Change in Control Purchase Date, a Put Right Purchase Date or the Final Maturity
Date money sufficient to pay the principal of (including premium, if any) and
accrued interest on Securities (or portions thereof) payable on that date, then
on and after such Redemption Date, Change in Control Purchase Date, Put Right
Purchase Date or Final Maturity Date, as the case may be, such Securities (or
portions thereof, as the case may be) shall cease to be outstanding and interest
and Original Issue Discount on them shall cease to accrue; provided that if such
Securities are to be redeemed, notice of such redemption has been duly given
pursuant to this Indenture or provision thereof satisfactory to the Trustee has
been made.

     (d)  Subject to the restrictions contained in Section 2.09, a Security does
not cease to be outstanding because the Company or an Affiliate of the Company
holds the Security.

     Section 2.09  Treasury Securities.

     In determining whether the Holders of the required principal amount of
Securities have concurred in any notice, direction, waiver or consent,
Securities owned by the Company or any other obligor on the Securities or by any
Affiliate of the Company or of such other obligor shall be disregarded, except
that, for purposes of determining whether the Trustee shall be protected in
relying on any such notice, direction, waiver or consent, only Securities which
a Trust Officer of the Trustee actually knows are so owned shall be so
disregarded. Securities so owned which have been pledged in good faith shall not
be disregarded if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to the Securities and that the pledgee is
not the Company or any other obligor on the Securities or any Affiliate of the
Company or of such other obligor.

     Section 2.10  Temporary Securities.

     Until definitive Securities are ready for delivery, the Company may prepare
and execute, and, upon receipt of a Company Order, the Trustee shall
authenticate and deliver, temporary Securities. Temporary Securities shall be
substantially in the form of definitive Securities but may have variations that
the Company with the consent of the Trustee considers appropriate for temporary
Securities. Without unreasonable delay, the Company shall prepare and the
Trustee shall authenticate and deliver definitive Securities in exchange for
temporary Securities.

                                       14

<PAGE>

     Section 2.11  Cancellation.

     The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar, the Paying Agent and the Conversion Agent shall
forward to the Trustee or its agent any Securities surrendered to them for
transfer, exchange, redemption, purchase, payment or conversion. The Trustee and
no one else shall cancel, in accordance with its standard procedures, all
Securities surrendered for transfer, exchange, redemption, purchase, payment,
conversion or cancellation and shall dispose of the cancelled Securities in
accordance with its customary procedures or deliver the canceled Securities to
the Company. All Securities which are redeemed, purchased or otherwise acquired
by the Company or any of its Subsidiaries prior to the Final Maturity Date
pursuant to Article 3 shall be delivered to the Trustee for cancellation, and
the Company may not hold or resell such Securities or issue any new Securities
to replace any such Securities or any Securities that any Holder has converted
pursuant to Article 4.

     Section 2.12  Legend; Additional Transfer And Exchange Requirements.

     (a)  If Securities are issued upon the transfer, exchange or replacement of
Securities subject to restrictions on transfer and bearing the legends set forth
on the forms of Securities attached hereto as Exhibit A (collectively, the
"Legend"), or if a request is made to remove the Legend on a Security, the
Securities so issued shall bear the Legend, or the Legend shall not be removed,
as the case may be, unless there is delivered to the Company and the Registrar
such satisfactory evidence, which shall include an opinion of counsel if
requested by the Company or such Registrar, as may be reasonably required by the
Company and the Registrar, that neither the Legend nor the restrictions on
transfer set forth therein are required to ensure that transfers thereof comply
with the provisions of Rule 144A, Rule 144 or Regulation S under the Securities
Act or that such Securities are not "restricted" within the meaning of Rule 144
under the Securities Act; provided that no such evidence need be supplied in
connection with the sale of such Security pursuant to a registration statement
that is effective at the time of such sale. Upon (1) provision of such
satisfactory evidence if requested, or (2) notification by the Company to the
Trustee and Registrar of the sale of such Security pursuant to a registration
statement that is effective at the time of such sale, the Trustee, at the
written direction of the Company, shall authenticate and deliver a Security that
does not bear the Legend. If the Legend is removed from the face of a Security
and the Security is subsequently held by an Affiliate of the Company, the Legend
shall be reinstated.

     (b)  A Global Security may not be transferred, in whole or in part, to any
Person other than the Depositary or a nominee or any successor thereof, and no
such transfer to any such other Person may be registered; provided that the
foregoing shall not prohibit any transfer of a Security that is issued in
exchange for a Global Security but is not itself a Global Security. No transfer
of a Security to any Person shall be effective under this Indenture or the
Securities unless and until such Security has been registered in the name of
such Person. Notwithstanding any other provisions of this Indenture or the
Securities, transfers of a Global Security, in whole or in part, shall be made
only in accordance with this Section 2.12.

     (c)  Subject to the succeeding paragraph, every Security shall be subject
to the restrictions on transfer provided in the Legend other than a Restricted
Global Security. Whenever any Restricted Security other than a Restricted Global
Security is presented or surrendered for registration of transfer or for
exchange for a Security registered in a name other than that of the Holder, such
Security must be accompanied by a certificate in substantially the form set
forth in Exhibit A, dated the date of such surrender and signed by the Holder of
such Security, as to compliance with such restrictions on transfer. The
Registrar shall not be required to accept for such registration of transfer or
exchange any Security not so accompanied by a properly completed certificate.

                                       15

<PAGE>

     (d)  The restrictions imposed by the Legend upon the transferability of any
Security shall cease and terminate when such Security has been sold pursuant to
an effective registration statement under the Securities Act or transferred in
compliance with Rule 144 under the Securities Act (or any successor provision
thereto) or, if earlier, upon the expiration of the holding period applicable to
sales thereof under Rule 144(k) under the Securities Act (or any successor
provision). Any Security as to which such restrictions on transfer shall have
expired in accordance with their terms or shall have terminated may, upon a
surrender of such Security for exchange to the Registrar in accordance with the
provisions of this Section 2.12 (accompanied, in the event that such
restrictions on transfer have terminated by reason of a transfer in compliance
with Rule 144 or any successor provision, by, if requested by the Company or the
Registrar, an opinion of counsel reasonably acceptable to the Company and
addressed to the Company in form acceptable to the Company, to the effect that
the transfer of such Security has been made in compliance with Rule 144 or such
successor provision), be exchanged for a new Security, of like tenor and
aggregate Principal Amount at Maturity, which shall not bear the restrictive
Legend. The Company shall inform the Trustee of the effective date of any
registration statement registering the offer and sale of the Securities under
the Securities Act. The Trustee shall not be liable for any action taken or
omitted to be taken by it in good faith in accordance with the aforementioned
opinion of counsel or registration statement.

As used in the preceding Subsections 2.12(c) and (d), the term "transfer"
encompasses any sale, pledge, transfer, hypothecation or other disposition of
any Security.

     (e)  The provisions below shall apply only to Global Securities:

          (1)  Notwithstanding any other provisions of this Indenture or the
     Securities, a Global Security shall not be exchanged in whole or in part
     for a Security registered in the name of any Person other than the
     Depositary or one or more nominees thereof, provided that a Global Security
     may be exchanged for Securities registered in the names of any person
     designated by the Depositary in the event that (A) the Depositary has
     notified the Company that it is unwilling or unable to continue as
     Depositary for such Global Security or such Depositary has ceased to be a
     "clearing agency" registered under the Exchange Act, and a successor
     Depositary is not appointed by the Company within 90 days of receiving such
     notice or becoming aware that the Depositary has ceased to be a "clearing
     agency", or (B) an Event of Default has occurred and is continuing with
     respect to the Securities. Any Global Security exchanged pursuant to
     subclause (A) immediately above shall be so exchanged in whole and not in
     part, and any Global Security exchanged pursuant to subclause (B) above may
     be exchanged in whole or from time to time in part as directed by the
     Depositary. Any Security issued in exchange for a Global Security or any
     portion thereof shall be a Global Security; provided that any such Security
     so issued that is registered in the name of a Person other than the
     Depositary or a nominee thereof shall not be a Global Security.

          (2)  Securities issued in exchange for a Global Security or any
     portion thereof shall be issued in definitive, fully registered form,
     without interest coupons, shall have an aggregate Principal Amount at
     Maturity equal to that of such Global Security or portion thereof to be so
     exchanged, shall be registered in such names and be in such authorized
     denominations as the Depositary shall designate and shall bear the
     applicable legends provided for herein. Any Global Security to be exchanged
     in whole shall be surrendered by the Depositary to the Trustee, as
     Registrar. With regard to any Global Security to be exchanged in part,
     either such Global Security shall be so surrendered for exchange or, if the
     Trustee is acting as custodian for the Depositary or its nominee with
     respect to such Global Security, the Principal Amount at Maturity thereof
     shall be reduced, by an amount equal to the portion thereof to be so
     exchanged, by means of an appropriate adjustment made on the records of the
     Trustee. Upon any such surrender or

                                       16

     adjustment, the Trustee shall authenticate and deliver the Security
     issuable on such exchange to or upon the order of the Depositary or an
     authorized representative thereof.

          (3)  Subject to the provisions of clause (5) of this Subsection
     2.12(e), the registered Holder may grant proxies and otherwise authorize
     any Person, including Agent Members and Persons that may hold interests
     through Agent Members, to take any action which a Holder is entitled to
     take under this Indenture or the Securities.

          (4)  In the event of the occurrence of any of the events specified in
     clause (1) of this Subsection 2.12(e) above, the Company will promptly make
     available to the Trustee a reasonable supply of Certificated Securities in
     definitive, fully registered form, without interest coupons.

          (5)  Neither Agent Members nor any other Persons on whose behalf
     Agent Members may act shall have any rights under this Indenture with
     respect to any Global Security registered in the name of the Depositary or
     any nominee thereof, or under any such Global Security, and the Depositary
     or such nominee, as the case may be, may be treated by the Company, the
     Trustee and any agent of the Company or the Trustee as the absolute owner
     and holder of such Global Security for all purposes whatsoever.
     Notwithstanding the foregoing, nothing herein shall prevent the Company,
     the Trustee or any agent of the Company or the Trustee from giving effect
     to any written certification, proxy or other authorization furnished by the
     Depositary or such nominee, as the case may be, or impair, as between the
     Depositary, its Agent Members and any other Person on whose behalf an Agent
     Member may act, the operation of customary practices of such Persons
     governing the exercise of the rights of a holder of any Security.

     Section 2.13  CUSIP Numbers.

     The Company in issuing the Securities may use one or more "CUSIP" numbers
(if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption or purchase 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 on the Securities or as contained in any notice
of a redemption or purchase and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption or
purchase 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 III

                             REDEMPTION AND PURCHASE

     Section 3.01  To Redeem; Notice To Trustee.

     (a)  Prior to March 2, 2007, the Securities shall not be redeemable. The
Company may, at its option, redeem the Securities for cash, as a whole at any
time or from time to time in part:

          (i)   On or after March 2, 2007 and on or prior to March 1, 2008 at a
     Redemption Price of 101.286% of the Issue Price;

          (ii)  On or after March 2, 2008 and on or prior to March 1, 2009 at a
     Redemption Price of 100.964% of the Issue Price;

          (iii) On or after March 2, 2009 and on or prior to March 1, 2010 at a
     Redemption Price of 100.643% of the Issue Price;

                                       17

<PAGE>

          (iv)  On or after March 2, 2010 and on or prior to March 1, 2011 at a
     Redemption Price of 100.321% of the Issue Price; and

          (v)   On or after March 2, 2011 at a Redemption Price of 100% of the
     Issue Price of the Securities plus accrued Original Issue Discount,

in each case together with any accrued and unpaid cash interest, if any, and
accrued and unpaid Liquidated damages, if any, up to but not including the
applicable Redemption Date. If the Redemption Date falls after a Regular Record
Date and on or before the related Interest Payment Date, then cash interest on
the Securities payable on such Interest Payment Date will be payable to the
Holders in whose names the Securities are registered at the close of business on
such Regular Record Date.

     (b)  If the Company elects to redeem Securities pursuant to this Section
3.01, it shall notify the Trustee on a date at least 30 days and no more than 60
days prior to the Redemption Date, as fixed by the Company (unless a shorter
notice shall be satisfactory to the Trustee), of the Redemption Date and the
principal amount of Securities to be redeemed. If fewer than all of the
Securities are to be redeemed, the record date relating to such redemption shall
be selected by the Company and given to the Trustee, which record date shall not
be less than five days after the date of notice to the Trustee.

     Section 3.02  Selection Of Securities To Be Redeemed.

     (a)  If less than all of the Securities are to be redeemed, unless the
procedures of the Depositary provide otherwise, the Trustee shall, select the
Securities to be redeemed within five Business Days after it receives the notice
provided for in Section 3.01(b). The Trustee shall make the selection from the
Securities outstanding and not previously called for redemption by lot, or in
its discretion, on a pro rata basis or by another method that the Trustee
considers fair and appropriate (so long as such method is not prohibited by the
rules of any stock exchange on which the Securities are listed). Securities in
denominations of $1,000 may only be redeemed in whole. The Trustee may select
for redemption portions (equal to $1,000 or any integral multiple thereof) of
the Principal Amount at Maturity of Securities that have denominations larger
than $1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption.
Securities and portions of them the Trustee selects shall be in Principal
Amounts at Maturity of $1,000 or an integral multiple of $1,000. Provisions of
this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption. The Trustee shall notify the
Company promptly of the Securities or portions of Securities to be redeemed.

     (b)  If any Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed (so
far as it may be) to be the portion selected for redemption. Securities which
have been converted subsequent to the Trustee commencing selection of Securities
to be redeemed but prior to redemption of such Securities shall be treated by
the Trustee as outstanding for the purpose of such selection.

     Section 3.03  Notice Of Redemption.

     (a)  At least 20 days but not more than 60 days before a Redemption Date,
the Company shall mail or cause to be mailed a notice of redemption to each
Holder of Securities to be redeemed at such Holder's address as it appears on
the Registrar's books.

     (b)  The notice shall identify the Securities (including CUSIP numbers) to
be redeemed and shall state:

                                       18

<PAGE>

          (1)  the Redemption Date;

          (2)  the Redemption Price and accrued and unpaid cash interest, if
     any, and accrued and unpaid Liquidated Damages, if any, payable on the
     Redemption Date;

          (3)  the then effective Conversion Price and Conversion Rate;

          (4)  the name and address of each Paying Agent and Conversion Agent;

          (5)  that Securities called for redemption must be presented and
     surrendered to a Paying Agent to collect the Redemption Price;

          (6)  that Holders who wish to convert Securities must surrender such
     Securities for conversion no later than the close of business on the
     Business Day immediately preceding the Redemption Date and must satisfy the
     other requirements set forth in paragraph 9 of the Securities and Article 4
     hereof;

          (7)  that, unless the Company defaults in making the payment of such
     Redemption Price and accrued and unpaid cash interest, if any and accrued
     and unpaid Liquidated Damages, if any, which is due and payable, Original
     Issue Discount and cash interest and Liquidated Damages, if any, will cease
     to accrue on and after the Redemption Date;

          (8)  if any Security is being redeemed in part, the portion of the
     Principal Amount at Maturity of such Security to be redeemed and that,
     after the Redemption Date, upon presentation and surrender of such
     Security, a new Security or Securities in aggregate Principal Amount at
     Maturity equal to the unredeemed portion thereof will be issued; and

          (9)  if fewer than all the outstanding Securities are to be redeemed,
     the certificate number and the Principal Amounts at Maturity of the
     particular Securities to be redeemed.

     (c)  If any of the Securities to be redeemed is in the form of a Global
Security, then the Company shall modify such notice to the extent necessary to
accord with the procedures of the Depositary applicable to redemptions. At the
Company's written request, which request shall (1) be irrevocable once given and
(2) set forth all relevant information required by clauses (1) through (8) of
Subsection 3.03(b), the Trustee shall give the notice of redemption to each
Holder in the Company's name and at the Company's expense.

     At the Company's request, the Trustee shall give such notice of redemption
on behalf of the Company and at the Company's expense; provided, however, that,
in all cases, the text of such notice of redemption shall be prepared by the
Company, and provided, further, that the Company must make such request at least
five Business Days prior to the date by which such Notice of Redemption must be
given to the Holders in accordance with this Section 3.03.

     Section 3.04  Effect Of Notice Of Redemption.

     Once notice of redemption is mailed, Securities called for redemption
become due and payable on the Redemption Date and at the Redemption Price stated
in the notice, together with any accrued and unpaid cash interest, if any, and
any accrued and unpaid Liquidated Damages, if any, up to but not including the
Redemption Date, stated in the notice, except for Securities that are converted
in accordance with the provisions of Article 4. On or after the Redemption Date
and upon presentation and surrender to a Paying Agent, Securities called for
redemption shall be paid at the Redemption Price, plus any accrued

                                       19

<PAGE>

and unpaid cash interest, if any, and any accrued and unpaid Liquidated Damages,
if any, up to but not including the Redemption Date.

     Section 3.05  Deposit Of Redemption Price.

     (a)  Prior to 11:00 a.m., New York City time, on the Redemption Date, the
Company shall deposit with a Paying Agent (or, if the Company acts as Paying
Agent, shall segregate and hold in trust) an amount of money (in immediately
available funds if deposited on such Redemption Date) sufficient to pay the
Redemption Price of, and accrued and unpaid cash interest, if any, and accrued
and unpaid Liquidated Damages, if any, payable upon redemption on all Securities
to be redeemed on that date, other than Securities or portions thereof called
for redemption on that date which have been delivered by the Company to the
Trustee for cancellation or have been converted. The Paying Agent shall as
promptly as practicable return to the Company any money not required for that
purpose because of the cancellation of Securities or the conversion of
Securities pursuant to Article 4 or, if such money is then held by the Company
in trust and is not required for such purpose, it shall be discharged from the
trust.

     (b)  If a Paying Agent holds, in accordance with the terms hereof, money
sufficient to pay the Redemption Price of any Security for which a Notice of
Redemption has been tendered and not withdrawn in accordance with this Indenture
then, on the Redemption Date, such Security will cease to be outstanding,
whether or not the Security is delivered to the Paying Agent, and the rights of
the Holder in respect thereof shall terminate (other than the right to receive
the Redemption Price as aforesaid).

     Section 3.06  Securities Redeemed In Part.

     Upon presentation and surrender of a Security that is redeemed in part, the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder a new Security equal in Principal Amount at Maturity to the unredeemed
portion of the Security surrendered.

     Section 3.07  Conversion Arrangement On Call For Redemption.

     In connection with any redemption of Securities, the Company may arrange
for the purchase and conversion of any Securities called for redemption by an
agreement with one or more investment banks or other purchasers to purchase such
Securities by paying to a Paying Agent (other than the Company or any of its
Affiliates) in trust for the Holders, on or before 11:00 a.m., New York City
time, on the Redemption Date, an amount that, together with any amounts
deposited with such Paying Agent by the Company for the redemption of such
Securities, is not less than the Redemption Price, together with, accrued and
unpaid cash interest if any, and accrued and unpaid Liquidated Damages, if any,
to, but not including, the Redemption Date of such Securities. Notwithstanding
anything to the contrary contained in this Article 3, the obligation of the
Company to pay the Redemption Price of such Securities, including accrued and
unpaid cash interest, if any, and accrued and unpaid Liquidated Damages, if any,
shall be deemed to be satisfied and discharged to the extent such amount is so
paid by such purchasers; provided, however, that nothing in this Section 3.07
shall relieve the Company of its obligation to pay the Redemption Price, plus
any accrued and unpaid cash interest, if any, and accrued and unpaid Liquidated
Damages, if any, to but excluding the relevant Redemption Date, on Securities
called for redemption. If such an agreement with one or more investment banks or
other purchasers is entered into, any Securities called for redemption and not
surrendered for conversion by the Holders thereof prior to the relevant
Redemption Date may, at the option of the Company upon written notice to the
Trustee, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such Holders and (notwithstanding anything to the contrary
contained in Article 4) surrendered by such purchasers for conversion, all as of
11:00 a.m., New York City time, on the Redemption Date, subject to payment of
the above amount as aforesaid. The Paying Agent shall hold and pay to the
Holders whose Securities are selected for redemption any such amount

                                       20

<PAGE>

paid to it for purchase in the same manner as it would money deposited with it
by the Company for the redemption of Securities. Without the Paying Agent's
prior written consent, no arrangement between the Company and such purchasers
for the purchase and conversion of any Securities shall increase or otherwise
affect any of the powers, duties, responsibilities or obligations of the Paying
Agent as set forth in this Indenture, and the Company agrees to indemnify the
Paying Agent from, and hold it harmless against, any loss, liability or expense
arising out of or in connection with any such arrangement for the purchase and
conversion of any Securities between the Company and such purchasers, including
the costs and expenses incurred by the Paying Agent 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 3.08  Purchase Of Securities At Option Of The Holder Upon Change In
Control.

     (a)  If at any time the Securities remain outstanding there shall have
occurred a Change in Control, all or any portion of the Securities of any Holder
equal to $1,000 or a integral multiple of $1,000 Principal Amount at Maturity,
shall be purchased by the Company, at the option of such Holder, at a purchase
price equal to the Issue Price of the Securities to be purchased, together with
accrued Original Issue Discount, accrued and unpaid cash interest, if any, and
accrued and unpaid Liquidated Damages, if any, to, but excluding, the Change in
Control Purchase Date (the "Change in Control Purchase Price"), on a date
specified by the Company that is no more than 30 Business Days after the date of
the Change in Control (the "Change in Control Purchase Date"); provided,
however, if the Change in Control Purchase Date falls after a Regular Record
Date and on or before the related Interest Payment Date, then interest on the
Securities payable on such Interest Payment Date shall be payable to the Holders
in whose name the Securities are registered at the close of business on such
Regular Record Date.

     (b)  Whenever in this Indenture (including Sections 2.01, 8.01 and 8.07
hereof) or in the form of Securities there is a reference, in any context, to
the principal of any Securities as of any time, such reference shall be deemed
to include reference to the Change in Control Purchase Price payable in respect
to such Securities to the extent that such Change in Control Purchase Price is,
was or would be so payable at such time, and express mention of the Change in
Control Purchase Price in any provision of this Indenture shall not be construed
as excluding the Change in Control Purchase Price in those provisions of this
Indenture when such express mention is not made.

     (c)  A "Change in Control" of the Company, or any successor entity who is
subject to the terms of this Indenture, shall be deemed to have occurred at such
time after the original issuance of Securities as any of the following events
shall occur:

          (1)  a resolution is passed by the Company's shareholders approving a
     plan of liquidation or dissolution of the Company;

          (2)  the consummation of any transaction with respect to the Company's
     Common Stock that is subject to Rule 13e-3 of the Securities Act;

          (3)  any person acquires in one or more transactions an amount of the
     Company's Common Stock which is at the time of such acquisition great
     enough to result in the Company's Common Stock being delisted from the
     principal United States national securities exchange (or the NASDAQ
     National Market) on which the shares of the Company's Common Stock are then
     listed;

          (4)  the acquisition by any person of beneficial ownership, directly
     or indirectly, through a purchase, merger (except a merger or consolidation
     described in subclause (5) of this

                                       21

<PAGE>

     Subsection) or other acquisition transaction or series of transactions, of
     shares of the Capital Stock of the Company entitling a person, the Company,
     its Subsidiaries, their employee benefit plans, or any combination of the
     foregoing, to exercise more than 50% of the aggregate voting power of all
     shares of such Capital Stock entitled to vote generally in the election of
     at least a majority of the Company's directors; or

          (5)  any merger or consolidation of the Company with or into any other
     person, any merger of another person into the Company, or any conveyance,
     transfer, sale, lease or other disposition (other than by way of merger or
     consolidation), in one or a series of related transactions, of all or
     substantially all of the properties and assets of the Company and its
     subsidiaries taken as a whole to another person (other than to one or more
     direct or indirect wholly-owned Subsidiaries of the Company), other than:

               (A)  any transaction pursuant to which holders of 50% or more of
          the total voting power of all shares of the Capital Stock of the
          Company entitled to vote generally in the election of directors
          immediately prior to the transaction are entitled to exercise,
          directly or indirectly, 50% or more of the total voting power of all
          shares of the Capital Stock of the continuing, surviving and/or
          acquiring person entitled to vote generally in the election of
          directors of the continuing, surviving and/or acquiring person
          immediately after the transaction; or

               (B)  any merger solely for the purpose of changing the Company's
          jurisdiction of incorporation to any State within the United States or
          the District of Columbia and resulting in a reclassification,
          conversion or exchange of outstanding shares of Common Stock solely
          into shares of common stock of the surviving entity.

     Notwithstanding anything to the contrary set forth in this Section 3.08, a
     Change in Control will be deemed not to have occurred if in the case of a
     merger or consolidation, 90% of the consideration (excluding cash payments
     for fractional shares and cash payments made pursuant to dissenters'
     appraisal rights) in a merger or consolidation otherwise constituting a
     Change in Control consists of shares of common stock, depositary receipts,
     ordinary shares or other certificates representing common equity interests
     traded on a U.S. national securities exchange or quoted on the NASDAQ
     National Market, or will be so traded or quoted immediately following such
     merger or consolidation, and as a result of such merger or consolidation
     the notes become convertible into such common stock, depositary receipts,
     ordinary shares or other certificates representing common equity interests.

     (d)  Beneficial ownership shall be determined in accordance with Rule 13d-3
promulgated by the SEC under the Exchange Act. The term "person" shall include
any syndicate or group that would be deemed to be a "person" under Section
13(d)(3) of the Exchange Act.

     (e)  Within 15 days after the occurrence of a Change in Control (or, at the
Company's option, prior to the occurrence of the Change in Control, if such
Change in Control has been publicly announced) the Company, or, at the written
request and expense of the Company, the Trustee, shall mail a written notice of
the Change in Control to the Trustee (if the Trustee does not mail such notice)
and to each Holder (and to beneficial owners as required by applicable law). The
notice shall include the form of a Change in Control Purchase Notice to be
completed by the Holder and shall state:

          (1)  the date of such Change in Control and, briefly, the events
     causing such Change in Control;

                                       22

          (4)  the Change in Control Purchase Price;

          (5)  the Holder's right to require the Company to purchase the
     Securities;

          (6)  briefly, the conversion rights of the Securities;

          (7)  the name and address of each Paying Agent and Conversion Agent
     and that the Securities must be surrendered to the Paying Agent to collect
     payment;

          (8)  the then effective Conversion Price and Conversion Rate;

          (9)  the procedures that the Holder must follow to exercise rights
     under Article 4 and that Securities as to which a Change in Control
     Purchase Notice has been given may be converted into Common Stock pursuant
     to Article 4 of this Indenture only to the extent that the Change in
     Control Purchase Notice has been withdrawn in accordance with the terms of
     this Indenture;

          (10) the procedures that the Holder must follow to exercise rights
     under this Section 3.08

          (11) the procedures for withdrawing a Change in Control Purchase
     Notice, including a form of notice of withdrawal; and

          (12) that, unless the Company defaults in making the payment of such
     Change in Control Purchase Price and accrued and unpaid cash interest, if
     any and accrued and unpaid Liquidated Damages, if any, which is due and
     payable, Original Issue Discount and cash interest and Liquidated Damages,
     if any, will cease to accrue on and after the Change in Control Purchase
     Date.

     If any of the Securities is in the form of a Global Security, then the
Company shall modify such notice to the extent necessary to accord with the
procedures of the Depositary applicable to the purchase of Global Securities.

     (f)  A Holder may exercise its rights specified in Subsection (a) of this
Section 3.08 upon delivery of a written notice (which shall be in substantially
the form included in Exhibit A hereto and which may be delivered by letter,
overnight courier, hand delivery, facsimile transmission or in any other written

          (1)  The delivery of such Security to any Paying Agent prior to, on or

     endorsements) at the office of such Paying Agent shall be a condition to
     the receipt by the Holder of the Change in Control Purchase Price therefor.

     Section 3.08, a portion of a Security if the Principal Amount at Maturity
     of such portion is $1,000 or an integral multiple of $1,000 (provisions of
     this Indenture that apply to the purchase of all of a Security also apply
     to the purchase of such portion of such Security).

          (3)  Notwithstanding anything herein to the contrary, any Holder

     (a)  Upon receipt by any Paying Agent of a properly completed Change in
Control Purchase Notice from a Holder, the Holder of the Security in respect of
which such Change in Control Purchase Notice was given shall (unless such Change

promptly following the later of (1) the Change in Control Purchase Date
(provided that the conditions in Subsection 3.08(h) have been satisfied) and (2)
the time of delivery of such Security to a Paying Agent by the Holder thereof in

Purchase Date, the Company shall deposit with the Trustee or with a Paying Agent
(other than the Company or an Affiliate of the Company) an amount of money (in
immediately available funds if deposited on such Change in Control Purchase
Date), sufficient to pay the aggregate Change in Control Purchase Price of all

                                       24

<PAGE>

the Securities or portions thereof that are to be purchased on such Change in
Control Purchase Date provided that, such deposit shall be made in a manner such
that the Trustee or a Paying Agent shall have immediately available funds on the
Change in Control Purchase Date.

     (b)  If a Paying Agent holds, in accordance with the terms hereof, money
sufficient to pay the Change in Control Purchase Price of any Security for which
a Change in Control Purchase Notice has been tendered and not withdrawn in
accordance with this Indenture then, on the Change in Control Purchase Date,
such Security will cease to be outstanding, whether or not the Security is
delivered to the Paying Agent and the rights of the Holder in respect thereof
shall terminate (other than the right to receive the Change in Control Purchase
Price as aforesaid). The Company shall publicly announce the principal amount of
Securities repurchased on or as soon as practicable after the Change in Control
Purchase Date.

     (c)  No Securities may be purchased at the option of Holders upon a Change
in Control if there has occurred and is continuing an Event of Default with
respect to the Securities, other than a Default in the payment of the Change in
Control Purchase Price with respect to the Securities.

     Section 3.11  Repayment To The Company.

     To the extent that the aggregate amount of cash deposited by the Company
pursuant to Section 3.10 exceeds the aggregate Change in Control Purchase Price
of the Securities or portions thereof that the Company is obligated to purchase,
then promptly after the Change in Control Purchase Date the Trustee or a Paying
Agent, as the case may be, shall return any such excess cash.

     Section 3.12  Purchase Of Securities At Option Of The Holder On Specified

     (a)  Securities shall be purchased in cash in whole or in part (which must
be equal to $1,000 Principal Amount at Maturity or any integral multiple
thereof) by the Company, at the option of Holders, in accordance with the
provisions of this Article 3 and paragraph 8 of the Securities promptly after
March 2, 2011, March 2, 2014 and March 2, 2019 (each, a "Put Right Purchase

together with any accrued and unpaid cash interest, if any, and accrued and
unpaid Liquidated Damages, if any, up to but not including the applicable Put
Right Purchase Date (the "Put Right Purchase Price"); provided that if the Put

related Interest Payment Date, then interest on the Securities payable on such
Interest Payment Date will be payable to the Holders in whose names the
Securities are registered at the close of business on such Regular Record Date.

     (b)  The Company shall give written notice of the applicable Put Right
Purchase Date by notice sent by first-class mail to the Trustee and to each
Holder (at its address shown in the register of the Registrar) not less than 20
Business Days prior to each Put Right Purchase Date (the "Company Put Right
Notice"). Each Company Put Right Notice shall include a form of Put Right
Purchase Notice to be completed by a Holder and shall state:

          (3)  that Securities as to which a Put Right Purchase Notice has been
     given may be converted if they are otherwise convertible only in accordance
     with Article 4 hereof and paragraph 9 of the Securities only to the extent
     that the Put Right Purchase Notice has been withdrawn in accordance with
     the terms of this Indenture;

          (4)  that Securities must be surrendered to the Paying Agent to
     collect payment;

          (5)  that the Put Right Purchase Price for any Security as to which a
     Put Right Purchase Notice has been given and not withdrawn will be paid
     promptly following the later of the Put Right Purchase Date and the time of
     surrender of such Security as described in subclause (4) above;

          (6)  the procedures the Holder must follow to exercise rights under
     this Section and a brief description of those rights;

          (7)  briefly, the conversion rights of the Securities;

          (8)  the procedures for withdrawing a Put Right Purchase Notice
     (including pursuant to the terms of Subsection 3.12(g));

          (9)  that, unless the Company defaults in making payment of such Put
     Right Purchase Price and accrued and unpaid cash interest, if any, accrued
     Original Issue Discount and accrued and unpaid Liquidated Damages, if any,
     which is due and payable, on Securities for which a Put Right Purchase
     Notice has been submitted, Original Issue Discount and cash interest and
     Liquidated Damages, if any, on such Securities will cease to accrue on and
     after the Put Right Purchase Date; and

          (10) the CUSIP number of the Securities;

     (c)  If any of the Securities are to be redeemed in the form of a Global
Security, the Company shall modify such notice to the extent necessary to accord
with the procedures of the Depositary applicable to repurchases.

     (d)  At the Company's request, the Trustee shall give such Company Put
Right Notice on behalf of the Company and at the Company's expense; provided,
however, that, in all cases, the text of such Company Put Right Notice shall be
prepared by the Company, and provided, further, that the Company must make such
request at least five Business Days prior to the date by which such Put Right
Notice must be given in accordance with this Section 3.12.

     (e)  To exercise its rights pursuant to this Section 3.12, the Holder shall
deliver to the Paying Agent a properly completed Put Right Purchase Notice at
any time from the opening of business on the date that is 20 Business Days prior
to the applicable Put Right Purchase Date until the close of business on the
Business Day immediately preceding the Put Right Purchase Date stating:

          (1)  if certificated Securities have been issued, the certificate
     number of the Security which the Holder will deliver to be purchased (or if
     the Securities are not certificated, the Put

                                       26

<PAGE>

     Right Purchase Notice must comply with the procedures of the Depositary
     applicable to purchases),

          (2)  the portion (which may be 100%) of the Principal Amount at
     Maturity of the Security which the Holder will deliver to be purchased,
     which portion must be a Principal Amount at Maturity of $1,000 or an
     integral multiple thereof, and

          (3)  that such Security shall be purchased as of the applicable Put
     Right Purchase Date pursuant to the terms and conditions in this Section
     3.12 and the Securities.

     (f)  The Company shall purchase all Securities with respect to which a Put
Right Purchase Notice is given and not withdrawn, upon the later of the
applicable Put Right Purchase Date and delivery of such Securities to the Paying
Agent (together with all necessary endorsements) at the offices of the Paying
Agent (if the Securities are not certificated, such delivery must comply with
the procedures of the Depositary applicable to purchases). Delivery of such
Security shall be a condition to receipt by the Holder of the Put Right Purchase
Price therefor. The Put Right Purchase Price shall be paid pursuant to this
Section 3.12 only if the Security delivered to the Paying Agent conforms in all
respects to the description thereof in the related Put Right Purchase Notice, as
determined by the Company.

     (g)  Notwithstanding anything herein to the contrary, any Holder delivering
to the Paying Agent the Put Right Purchase Notice contemplated by this Section
3.12 shall have the right to withdraw such Put Right Purchase Notice in whole or
in part at any time prior to the close of business on the Business Day
immediately preceding the Put Right Purchase Date by delivery of a written
notice of withdrawal to the Paying Agent specifying:

          (1)  the certificate number, if any, of the Security in respect of
     which such notice of withdrawal is being submitted (or, if the Securities
     are not certificated, the withdrawal notice must comply with the procedures
     of the Depositary applicable to withdrawals),

          (2)  the aggregate Principal Amount at Maturity of the Security (which
     must be equal to $1,000 or any integral multiple thereof) with respect to
     which such notice of withdrawal is being submitted, and

          (3)  the aggregate Principal Amount at Maturity, if any, of such
     Security which remains subject to the original Put Right Purchase Notice
     and which has been or will be delivered for purchase by the Company.

     (h)  The Paying Agent shall promptly notify the Company of the receipt by
it of any Put Right Purchase Notice or written notice of withdrawal thereof.

     (i)  On or before 11:00 a.m. (local time in the City of New York) on the
Business Day following the Put Right Purchase Date, the Company shall deposit
with the Trustee or with the Paying Agent (or if the Company or an Affiliate of
the Company is acting as the Paying Agent, shall segregate and hold in trust as
provided in Section 2.04) an amount of money (in immediately available funds if
deposited on or after such Put Right Purchase Date) sufficient to pay the
aggregate Put Right Purchase Price of all the Securities or portions thereof
which are to be purchased as of the Put Right Purchase Date.

          (1)  If a Paying Agent holds, in accordance with the terms hereof,
     money sufficient to pay the Put Right Purchase Price of any Security for
     which a Put Right Notice has been tendered and not withdrawn, then, on the
     Business Day after the Put Right Purchase Date, such Security will cease to
     be outstanding, whether or not the Security is delivered to the Paying
     Agent, and the

                                       27

<PAGE>

     rights of the Holder in respect thereof shall terminate (other than the
     right to receive the Put Right Purchase Price as aforesaid).

          (2)  The Put Right Purchase Price shall be paid to such Holder with
     respect to Securities for which a Put Right Purchase Notice has been
     tendered and not withdrawn, subject to receipt of funds by the Paying
     Agent, promptly following the later of (A) the applicable Put Right
     Purchase Date with respect to such Security (provided that the conditions
     in Subsection 3.12(f) have been satisfied) and (B) the time of delivery of
     such Security to the Paying Agent by the Holder thereof in the manner
     required by Section 3.12(f). Securities in respect of which a Put Right
     Purchase Notice has been given by the Holder thereof; if convertible
     pursuant to Article 4 hereof, may not be converted on or after the date of
     the delivery of such Put Right Purchase Notice, unless such Put Right
     Purchase Notice has first been validly withdrawn as specified in Subsection
     3.12(g).

          (3)  To the extent that the aggregate amount of cash deposited by the
     Company pursuant to this Subsection 3.12(i) exceeds the aggregate Put Right
     Purchase Price of the Securities or portions thereof that the Company is
     obligated to purchase, then promptly after the Put Right Purchase Date the
     Trustee or a Paying Agent, as the case may be, shall return any such excess
     cash to the Company, or if such money is then held by the Company in trust,
     it shall be discharged from the trust.

     (j)  The Company shall only be obligated to purchase, pursuant to this
Section 3.12, a portion of a Security if the Principal Amount at Maturity of
such portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the purchase of all of a Security also apply to the
purchase of such portion of such Security.

     (k)  No Securities may be purchased at the option of Holders if there has
occurred and is continuing an Event of Default with respect to the Securities,
other than a Default in the payment of the Put Right Purchase Price with respect
to such Securities.

     Section 3.13  Securities Purchased In Part.

     Any Security that is to be purchased only in part shall be surrendered at
the office of a Paying Agent, and promptly after the Change in Control Purchase
Date or the Put Right Purchase Date, as the case may be, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge, a new Security or Securities, of such
authorized denomination or denominations as may be requested by such Holder, in
aggregate Principal Amount at Maturity equal to, and in exchange for, the
portion of the Principal Amount at Maturity of the Security so surrendered that
is not purchased.

     Section 3.14  Compliance With Securities Laws Upon Purchase Of Securities.

     In connection with any offer to purchase of Securities under Section 3.08
or Section 3.12, the Company shall (a) comply with Rule 13e-4 and Rule 14e-1 (or
any successor to either such Rule), if applicable, under the Exchange Act, (b)
file the related Schedule TO (or any successor or similar schedule, form or
report) if required under the Exchange Act, and (c) otherwise comply with all
federal and state securities laws in connection with such offer to purchase or
purchase of Securities, all so as to permit the rights of the Holders and
obligations of the Company under Sections 3.08 through 3.12 to be exercised in
the time and in the manner specified therein.

     Section 3.15  Purchase Of Securities In Open Market.

     The Company (a) shall, on or prior to the date that is two years from the
latest issuance of any Securities in accordance with Section 2.11 surrender any
Security purchased by the Company pursuant to this Article 3 to the Trustee for
cancellation, and (b) after such date, may surrender such Security to the
Trustee for cancellation as aforesaid. Any Securities surrendered to the Trustee
for cancellation may not be reissued or resold by the Company and will be
canceled promptly in accordance with Section 2.11.

                                   ARTICLE IV

                                   CONVERSION

     Section 4.01  Conversion Privilege And Conversion Rate.

     (a)  Subject to and upon compliance with the provisions of this Article 4
and the Securities, at the option of the Holder thereof, any Security or portion
thereof that is an integral multiple of $1,000 Principal Amount at Maturity 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
prior to the close of business on the Final Maturity Date or such earlier date
set forth in this Article 4, unless previously redeemed to the Company or
purchased by the Company at the Holders' option, at the Conversion Rate,
determined as hereinafter provided, in effect at the time of conversion and
subject to the adjustments described below, only under the following
circumstances:

          (1)  prior to the Final Maturity Date, if, at any time after June 30,
     2004, as of the last day of the preceding calendar quarter, the Closing
     Price per share of the Common Stock was more than 120% of the then current
     accreted conversion price for at least 20 Trading Days in the period of the
     30 consecutive Trading Days ending on the last Trading Day of such calendar
     quarter (for avoidance of doubt, once that condition is satisfied for any
     quarter, the Securities will be convertible at any time at the option of
     the Holder through the Final Maturity Date);

          (2)  until the close of business on the second Business Day prior to
     the Redemption Date if the Company elects to redeem the relevant Security
     pursuant to Article 3 hereof;

          (3)  if the Company distributes to all or substantially all holders of
     Common Stock rights, options or warrants entitling them for a period
     expiring within 60 days of such distribution to purchase Common Stock at
     less than the Closing Price per share of the Common Stock on the day
     preceding the declaration date for such distribution;

          (4)  if the Company distributes to all or substantially all holders of
     Common Stock cash, assets, debt securities or capital stock (other than
     capital stock of the Company), which distribution has a per share value as
     determined by the Board of Directors exceeding 15% of the Closing Price per
     share of the Common Stock on the day preceding the declaration date for
     such distribution;

          (5)  if the Company becomes a party to a consolidation, merger or
     binding share exchange or a transfer of all or substantially all of its
     assets pursuant to which all or substantially all of the Company's Common
     Stock would be converted to cash, securities or other property); or

          (6)  during the five consecutive Business Day period following any
     five consecutive Trading Day period ending at any time on or prior to March
     2, 2019 in which the Trading Price for the Securities for each day of such
     five Trading Day period was less than 98% of the

                                       29

<PAGE>

     Conversion Value for the Securities for such Trading Day ("trading price
     condition"); provided that upon any conversion of Securities pursuant to
     this trading price condition if, on the Trading Day prior to applicable
     Conversion Date, the Closing Price per share of Common Stock is greater
     than the then current accreted conversion price of the Securities and less
     than or equal to 120% of the then current accreted conversion price of the
     Securities then such Holder shall receive, instead of shares of Common
     Stock calculated based on the Conversion Rate, cash or shares of Common
     Stock or a combination of cash and shares of Common Stock, at the option of
     the Company, with a value equal to the accreted principal amount of the
     Securities plus accrued and unpaid cash interest, if any, and accrued and
     unpaid Liquidated Damages, if any (a "Principal Value Conversion");
     provided, further, that any Common Stock delivered upon a Principal Value
     Conversion will be valued at the greater of the accreted conversion price
     of the Securities as of the Conversion Date and the applicable stock price
     (as defined below) as of the Conversion Date.

     (b)  Following the surrender of Securities by a Holder for a conversion
that is a Principal Value Conversion, the Company shall notify such Holder no
later than the first Business Day following the Conversion Date for such
Principal Value Conversion whether the Company shall pay the principal amount of
the Securities being converted in cash and/or shares of Common Stock. The
Company will deliver such cash and/or shares of Common Stock, together with any
cash payable for fraction shares, to such Holder no later than the tenth
Business Day following the Conversion Date. The "applicable stock price" shall
mean, in respect of any Conversion Date, the average of the Closing Price per
share of Common Stock over the five Trading Day period starting the third
Trading Day following the Conversion Date. The "Conversion Value" for the
Securities is equal to the product of (i) the Closing Price per share of the
Common Stock on a given day and (ii) the then current Conversion Rate. The
"Trading Price" of the Securities on any date of determination means the average
of the secondary market bid quotations obtained by the Bid Solicitation Agent
for $2,500,000 Principal Amount at Maturity of the Securities at approximately
4:00 p.m., New York City time, on such determination date from three independent
nationally recognized securities dealers the Company selects, which may include
one or more of the Initial Purchasers, provided that if three such bids cannot
reasonably be obtained by the Bid Solicitation Agent, but two such bids are
obtained, then the average of the two bids shall be used, and if only one such
bid can reasonably be obtained by the Bid Solicitation Agent, this one bid will
be used. If the Bid Solicitation Agent cannot reasonably obtain at least one bid
for $2,500,000 Principal Amount at Maturity of the Securities from a nationally
recognized securities dealer or if in the Company's reasonable judgment, the bid
quotations are not indicative of the secondary market value of the Securities,
then the Trading Price of the Securities will be deemed to be less than 98% of
the Conversion Value on such determination date.

     (c)  In the case of a distribution contemplated by clauses (3) and (4) of
Subsection 4.01(a), the Company shall notify Holders at least 20 days prior to
the date for such distribution (the "Distribution Notice"). Once the Company has
given the Distribution Notice, Holders may surrender their Securities for
conversion at any time until the earlier of the close of business on the last
Business Day preceding the date of such distribution or the Company's
announcement that such distribution will not take place. Notwithstanding the
foregoing, in the event of a distribution contemplated by clauses (3) and (4) of
Subsection 4.01(a), Holders may not convert the Securities if the Holders may
participate in such distribution without converting their Securities.

     (d)  In the case of a transaction contemplated by clause (5) of Subsection
4.01(a), the Company will notify Holders at least 25 days prior to the
anticipated effective date of such transaction (the "Merger Notice"). Holders
may surrender Securities for conversion at any time from and after the date
which is 15 days prior to the anticipated effective date of such transaction
until (but not including) the date which is 15 days after the actual effective
date of such transaction. At the effective time of the transaction, the right to
convert a Security into shares of Common Stock shall be changed into a right to

                                       30

<PAGE>

convert such Security into the kind and amount of cash, securities or other
property that the Holders would have received if the Holders had converted such
Security into shares of Common Stock immediately prior to the actual effective
time of the transaction. If such transaction also constitutes a Change in
Control, then the Holders may require the Company to purchase all or a portion
of the Securities as described in Section 3.08. Notwithstanding the foregoing,
the Securities will not become convertible by reason of a merger, consolidation
or other transaction effected with one of the Company's direct or indirect
Subsidiaries solely for the purpose of changing the Company's jurisdiction of
incorporation to any State within the United States or the District of Columbia.

     (e)  For each calendar quarter of the Company, beginning with the calendar
quarter ending June 30, 2004, (1) the Company or an agent for the Company will
determine, on the first Business Day following the last Trading Day of each
calendar quarter, whether the Securities are convertible pursuant to clause (1)
of Subsection 4.01(a), and, if so, will notify the Trustee and the Conversion
Agent in writing.

     (f)  The Trustee shall have no obligation to direct the Bid Solicitation
Agent to determine the Trading Price of the Securities unless the Company has
requested such determination; and the Company shall have no obligation to make
such request unless a Holder provides the Company with reasonable evidence that
the Trading Price of the Securities would be less than 98% of the Conversion
Value; at such time, the Company shall instruct the Trustee to direct the Bid
Solicitation Agent to determine the Trading Price of the Securities beginning on
the next Trading Day and on each successive Trading Day until the Trading Price
of the Securities is greater than or equal to 98% of the Conversion Value, and
to notify the Company accordingly.

     (g)  The Company will provide written notice to the Conversion Agent as
soon as reasonably practicable of any anticipated or actual event or transaction
that will cause or causes the Securities to become convertible pursuant to
clauses (3) or (4) of Subsection 4.01(a).

     (h)  The conversion right, subject to the conditions described in this
Section 4.01, shall commence on the initial issuance date of the Securities and
expire at the close of business on the Final Maturity Date, subject, in the case
of conversion of any Global Security, to any Applicable Procedures. If a
Security is called for redemption or submitted or presented for purchase
pursuant to Article 3, such conversion right shall terminate at the close of
business on the Business Day immediately preceding the Redemption Date, the
Change in Control Purchase Date or the Put Right Purchase Date, as the case may
be, for such Security (unless the Company shall default in making the Redemption
Price payment, Change in Control Purchase Price payment or Put Right Purchase
Price payment when due in accordance with Article 3, in which case the
conversion right shall terminate at the close of business on the date such
default is cured and such Security is redeemed or purchased, as the case may
be). Securities in respect of which a Change in Control Purchase Notice or a Put
Right Purchase Notice, as the case may be, has been delivered may not be
surrendered for conversion pursuant to this Article 4 prior to a valid
withdrawal of such Change in Control Notice or Put Right Purchase Notice, as the
case may be, in accordance with the provisions of Article 3.

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

     (j)  A Holder of Securities is not entitled to any rights of a holder of
Common Stock until such Holder has converted its Securities into Common Stock,
and only to the extent such Securities are deemed to have been converted into
Common Stock pursuant to this Article 4.

     (k)  The rate at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Rate") shall be initially 11.8821
shares of Common Stock for each $1,000

                                       31

<PAGE>

Principal Amount at Maturity of Securities. The Conversion Rate shall be
adjusted in certain instances as provided in this Article 4. The "Conversion
Price" shall equal $1,000 divided by the Conversion Rate and shall be adjusted
when the Conversion Price is so adjusted in accordance with this Article 4.

     (l)  By delivering the amount of cash and/or the number of shares of Common
Stock issuable on conversion (together with cash in lieu of any fractional
share), the Company will be deemed to have satisfied its obligation to pay the
Principal Amount at Maturity of the Securities so converted and its obligation
to pay accrued and unpaid cash interest, if any, attributable to the period from
the most recent Interest Payment Date through the Conversion Date (which amount
will be deemed paid in full rather than cancelled, extinguished or forfeited).

     Section 4.02  Conversion Procedure.

     (a)  To convert a Security, a Holder must (1) complete and manually sign
the conversion notice on the back of the Security and deliver such notice to a
Conversion Agent, (2) surrender the Security to a Conversion Agent, (3) furnish
appropriate endorsements and transfer documents if required by a Registrar or a
Conversion Agent, and (4) pay all transfer or similar taxes, if required. The
date on which the Holder satisfies all of those requirements is the "Conversion
Date." If the Company is required or elects to deliver Common Stock only on such
conversion, the Company shall deliver to the Holder through a Conversion Agent a
certificate for the number of whole shares of Common Stock issuable upon the
conversion and cash in lieu of any fractional shares pursuant to Section 4.03 no
later than the fifth Business Day following the Conversion Date. If the Company
elects to deliver cash only or cash and shares of Common Stock, the Company
shall deliver to the Holders through a Conversion Agent such cash (including
cash in lieu of any fractional shares pursuant to Section 4.03) and a
certificate for the number of whole shares of Common Stock issuable upon the
conversion, if any, no later than the tenth Business Day following the
Conversion Date. Anything herein to the contrary notwithstanding, in the case of
Global Securities, conversion notices may be delivered and such Securities may
be surrendered for conversion in accordance with the Applicable Procedures as in
effect from time to time.

     (b)  The person in whose name the shares of Common Stock issuable upon
conversion shall be deemed to be a holder of record of such Common Stock on the
later of (i) the Conversion Date, (ii) the expiration of the period in which the
Company may elect to deliver cash in lieu of shares of Common Stock, or (iii) if
the Company elects to deliver cash in lieu of some or all of such shares of
Common Stock, the date on which the amount of cash issuable per Security has
been determined; provided, however, that no surrender of a Security on any
Conversion Date when the stock transfer books of the Company shall be closed
shall be effective to constitute the person or persons entitled to receive the
shares of Common Stock upon conversion as the record holder or holders of such
shares of Common Stock on such date, but such surrender shall be effective to
constitute the person or persons entitled to receive such shares of Common Stock
as the record holder or holders thereof for all purposes at the close of
business on the next succeeding day on which such stock transfer books are open;
provided, further, that such conversion shall be at the Conversion Rate in
effect on the Conversion Date as if the stock transfer books of the Company had
not been closed. Upon conversion of a Security, such person shall no longer be a
Holder of such Security. Except as set forth in this Indenture, no payment or
adjustment will be made for dividends or distributions declared or made on
shares of Common Stock issued upon conversion of a Security prior to the
issuance of such shares.

     (c)  Securities so surrendered for conversion (in whole or in part) during
the period from the close of business on any Regular Record Date to the opening
of business on the next succeeding Interest Payment Date (excluding Securities
or portions thereof called for redemption) shall also be accompanied by payment
in funds acceptable to the Company of an amount equal to the interest payable on
such Interest Payment Date on the Principal Amount at Maturity of such Security
then being converted, and

                                       32

<PAGE>

such interest shall be payable to the registered Holder of such Security as of
that Regular Record Date notwithstanding the conversion of such Security,
subject to the provisions of this Indenture relating to the payment of defaulted
interest by the Company. Except as otherwise provided in this Section 4.02, no
payment or adjustment will be made for accrued cash interest or Original Issue
Discount on a converted Security.

     (d)  Nothing in this Section shall affect the right of a Holder in whose
name any Security is registered at the close of business on a Regular Record
Date to receive the interest payable on such Security on the related Interest
Payment Date in accordance with the terms of this Indenture, the Securities, the
Pledge Agreement and the Registration Rights Agreement. If a Holder converts
more than one Security at the same time, the number of shares of Common Stock
issuable upon the conversion (and the amount of any cash in lieu of fractional
shares pursuant to Section 4.03) shall be based on the aggregate Principal
Amount at Maturity of all Securities so converted.

     (e)  In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, without service charge, a new Security or
Securities of authorized denominations in an aggregate Principal Amount at
Maturity equal to the, and in exchange for, unconverted portion of the Principal
Amount at Maturity of such Security. A Security may be converted in part, but
only if the Principal Amount at Maturity of such part is an integral multiple of
$1,000 and the Principal Amount at Maturity of such Security to remain
outstanding after such conversion is equal to $1,000 or any integral multiple of
$1,000 in excess thereof.

     (f)  Upon the Company's determination that a Holder is or will be entitled
to convert their Notes into shares of Common Stock pursuant to this Article 4,
the Company will promptly after making such determination issue a press release
and use its reasonable efforts to post such information on the Company's website
or otherwise publicly disclose such information.

     Section 4.03  Fractional Shares.

     The Company will not issue fractional shares of Common Stock upon
conversion of Securities. In lieu thereof, the Company will pay an amount in
cash for the current market value of the fractional shares. The current market
value of a fractional share shall be determined (calculated to the nearest
1/100th of a share) by multiplying the Closing Price of the Common Stock on
the Conversion Date by such fractional share and rounding the product to the
nearest whole cent.

     Section 4.04  Taxes On Conversion.

     If a Holder converts a Security, the Company shall (subject to the
remainder of this Section 4.04) pay any transfer, stamp or similar taxes or
duties related to the issue or delivery of shares of Common Stock upon such
conversion. However, the Holder shall pay any such tax with respect to cash
received in lieu of fractional shares. In addition, the Holder shall pay any
such tax which is due because the Holder requests the shares to be issued in a
name other than the Holder's name. The Conversion Agent may refuse to deliver
the certificate representing the Common Stock being issued in a name other than
the Holder's name until the Conversion Agent receives a sum sufficient to pay
any tax which will be due because the shares are to be issued in a name other
than the Holder's name. Nothing herein shall preclude any tax withholding
required by law or regulation.

     Section 4.05  Company To Provide Stock.

     (a)  The Company shall, prior to issuance of any Securities hereunder, and
from time to time as may be necessary, reserve, out of its authorized but
unissued Common Stock, a sufficient number of shares of Common Stock to permit
the conversion of all outstanding Securities into shares of Common Stock.

     (b)  All shares of Common Stock delivered upon conversion of the Securities
shall be newly issued shares, shall be duly authorized, validly issued, fully
paid and nonassessable and shall be free from preemptive or similar rights and
free of any lien or adverse claim as the result of any action by the Company.

     (c)  The Company will endeavor promptly to comply with all federal and
state securities laws regulating the offer and delivery of shares of Common
Stock upon conversion of Securities, if any, and will list or cause to have
quoted such shares of Common Stock on each national securities exchange or on
the NASDAQ National Market or other over-the-counter market or such other market
on which the Common Stock is then listed or quoted; provided, however, that if
rules of such automated quotation system or exchange permit the Company to defer
the listing of such Common Stock until the first conversion of the Securities
into Common Stock in accordance with the provisions of this Indenture, the
Company covenants to list such Common Stock issuable upon conversion of the
Securities in accordance with the requirements of such automated quotation
system or exchange at such time. Any Common Stock issued upon conversion of a
Security hereunder which at the time of conversion was a Restricted Security
will also be treated as a Restricted Security.

     Section 4.06  Adjustment Of Conversion Rate.

     (a)  The Conversion Rate shall be adjusted from time to time by the Company
as follows:

          (1)  In case the Company shall pay a dividend on its Common Stock in
     shares of Common Stock or make a distribution on its Common Stock in shares
     of Common Stock, the Conversion Rate in effect immediately prior to the
     record date for the determination of shareholders entitled to receive such
     dividend or other distribution shall be increased so that the same shall
     equal the rate determined by multiplying the Conversion Rate in effect
     immediately prior to such record date by a fraction of which the numerator
     of shall be the sum of the number of shares of Common Stock outstanding at
     the close of business on such record date plus the total number of shares
     of Common Stock constituting such dividend or other distribution and of
     which the denominator shall be the number of shares of Common Stock
     outstanding at the close of business on such record date. Such adjustment
     shall be made successively whenever any such dividend or distribution is
     made and shall become effective immediately after such record date. For the
     purpose of this clause (1) of Subsection 4.06(a), the number of shares of
     Common Stock at any time outstanding shall not include shares held in the
     treasury of the Company. The Company will not pay any dividend or make any
     distribution on Common Shares held in the treasury of the Company. If any
     dividend or distribution of the type described in this clause is declared
     but not so paid or made, the Conversion Rate shall again be adjusted to the
     Conversion Rate that would then be in effect if such dividend or
     distribution had not been declared.

          (2)  In case the Company shall subdivide its outstanding Common Stock
     into a greater number of shares, or combine its outstanding Common Stock
     into a smaller number of shares, the Conversion Rate in effect immediately
     prior to the day upon which such subdivision or combination becomes
     effective shall be, in the case of a subdivision of Common Stock,
     proportionately increased and, in the case of a combination of Common
     Stock, proportionately

                                       34

<PAGE>

     reduced. Such adjustment shall be made successively whenever any such
     subdivision or combination of the Common Stock occurs and shall become
     effective immediately after the date upon which such subdivision or
     combination becomes effective.

          (3)  In case the Company shall issue rights, options or warrants to
     all holders of its Common Stock entitling them (for a period of not more
     than 60 days after such issuance) to subscribe for or purchase shares of
     Common Stock (or securities convertible into Common Stock) at a price per
     share (or having a conversion price per share) less than the Current Market
     Price per share of Common Stock (as determined in accordance with clause
     (10) of this Subsection 4.06(a)) on the record date for the determination
     of shareholders entitled to receive such rights, options or warrants, the
     Conversion Rate in effect immediately prior thereto shall be adjusted so
     that the same shall equal the rate determined by multiplying the Conversion
     Rate in effect immediately prior to such record date by a fraction of which
     the numerator shall be the number of shares of Common Stock outstanding at
     the close of business on such record date plus the number of additional
     shares of Common Stock offered (or into which the convertible securities so
     offered are convertible) and of which the denominator shall be the number
     of shares of Common Stock outstanding at the close of business on such
     record date plus the number of shares which the aggregate offering price of
     the total number of shares of Common Stock so offered (or the aggregate
     conversion price of the convertible securities so offered, which shall be
     determined by multiplying the number of shares of Common Stock issuable
     upon conversion of such convertible securities by the conversion price per
     share of Common Stock pursuant to the terms of such convertible securities)
     would purchase at the Current Market Price per share of Common Stock on
     such record date. Such adjustment shall be made successively whenever any
     such rights, options or warrants are issued, and shall become effective
     immediately after such record date. To the extent that shares of Common
     Stock are not delivered after the expiration of such rights, options or
     warrants, the Conversion Rate shall be readjusted to the Conversion Rate
     that would then be in effect had the adjustments made upon the issuance of
     such rights, options or warrants been made on the basis of delivery of only
     the number of Common Shares actually delivered. If such rights, options or
     warrants are not so issued, the Conversion Rate shall again be adjusted to
     be the Conversion Rate that would then be in effect if the record date for
     the determination of shareholders entitled to receive such rights, options
     or warrants had not been fixed. In determining whether any rights, options
     or warrants entitle the shareholders to subscribe for or purchase shares of
     Common Stock at a price less than the Current Market Price per share of
     Common Stock and in determining the aggregate offering price of the total
     number of shares of Common Stock so offered, there shall be taken into
     account any consideration received by the Company for such rights, options
     or warrants and any amount payable on exercise or conversion thereof, the
     value of such consideration, if other than cash, to be determined by the
     Board of Directors.

          (4)  In case the Company shall make a dividend or other distribution
     to all holders of its Common Stock of securities or other property
     (including evidences of indebtedness or other non-cash assets), including
     shares of capital stock or similar equity instruments (excluding (x) any
     dividend or distribution of Common Stock for which an adjustment was made
     pursuant to Section 4.06(a)(1), any subdivision or combination of Common
     Stock for which an adjustment was made pursuant to Section 4.06(a)(2), any
     issuance of rights, options or warrants for which an adjustment was made
     pursuant to Section 4.06(a)(3) and (y) any dividend or distribution paid
     exclusively in cash for which an adjustment was made pursuant to Section
     4.06(a)(7)) (the "Distributed Securities"), then in each such case the
     Conversion Rate in effect immediately prior to the record date fixed for
     the determination of shareholders entitled to receive such dividend or
     distribution shall be adjusted so that the same shall equal the rate
     determined by multiplying the Conversion Rate in effect immediately prior
     to such record date by a fraction of which the

                                       35

<PAGE>

     numerator shall be the Current Market Price per share of the Common Stock
     on such record date and of which the denominator shall be Current Market
     Price per share on such record date less the fair market value (as
     determined by the Board of Directors, whose determination shall be
     conclusive evidence of such fair market value and which shall be evidenced
     by an Officers' Certificate delivered to the Trustee) on such record date
     of the portion of the Distributed Securities so distributed applicable to
     one share of Common Stock (determined on the basis of the number of shares
     of Common Stock outstanding at the close of business on such record date).
     Such adjustment shall be made successively whenever any such distribution
     is made and shall become effective immediately after the record date for
     the determination of shareholders entitled to receive such distribution. In
     the event that such dividend or distribution is not so paid or made, the
     Conversion Rate shall again be adjusted to be the Conversion Rate that
     would then be in effect if such dividend or distribution had not been
     declared.

          In the event the then fair market value (as so determined) of the
     portion of the Distributed Securities so distributed applicable to one
     share of Common Stock is equal to or greater than the Current Market Price
     per share of the Common Stock on such record date, in lieu of the foregoing
     adjustment, adequate provision shall be made so that each holder of a
     Security shall have the right to receive upon conversion the amount of
     Distributed Securities so distributed such Holder would have received had
     such Holder converted each Security on such record date. If the Board of
     Directors determines the fair market value of any distribution for purposes
     of this Subsection 4.06(a)(4) by reference to the actual or when issued
     trading market for any securities, it must in doing so consider the prices
     in such market over the same period used in computing the Current Market
     Price of the Common Stock.

          Notwithstanding the foregoing, if the securities distributed by the
     Company to all holders of its Common Stock consist of capital stock of, or
     similar equity interests in, a Subsidiary or other business unit of the
     Company (the "Spinoff Securities"), the Conversion Rate shall be increased
     so that the same shall be equal to the rate determined by multiplying the
     Conversion Rate in effect on the record date fixed for the determination of
     shareholders entitled to receive such distribution by a fraction, the
     numerator of which shall be the sum of (A) the average Closing Price of one
     share of Common Stock over the ten consecutive Trading Day period (the
     "Spinoff Valuation Period") commencing on and including the fifth Trading
     Day after the date on which "ex-dividend trading" commences on the Common
     Stock on the NASDAQ National Market or such other U.S. national or regional
     exchange or market on which the Common Stock is then listed or quoted and
     (B) the average Closing Price over the Spinoff Valuation Period of the
     portion of the Spinoff Securities so distributed applicable to one share of
     Common Stock and the denominator of which shall be the average Closing
     Price of one share of Common Stock over the Spinoff Valuation Period, such
     adjustment to become effective immediately prior to the opening of business
     on the fifteenth Trading Day after the date on which "ex-dividend trading"
     commences; provided, however, that the Company may in lieu of the foregoing
     adjustment elect to reserve the pro rata portion of such Spinoff Securities
     so that each Holder of Securities shall have the right to receive upon
     conversion thereof the amount of such Spinoff Securities that such Holder
     of Securities would have received if such Securities had been converted on
     the record date with respect to such distribution.

          (5)  With respect to any rights or warrants (the "Rights") that may be
     issued or distributed pursuant to the Company's existing rights plan and
     any rights plan that the Company implements after the date of this
     Indenture (each a "Rights Plan"), upon conversion of the Securities into
     Common Stock, to the extent that such Rights Plan is in effect upon such
     conversion, the Holders of Securities will receive, with respect to the
     shares of Common Stock issued upon conversion, the Rights described therein
     (whether or not the Rights have separated

                                       36

<PAGE>

     from the Common Stock at the time of conversion), subject to the
     limitations set forth in and in accordance with any such Rights Plan;
     provided that if, at the time of conversion, however, the Rights have
     separated from the shares of Common Stock in accordance with the provisions
     of the Rights Plan so that Holders would not be entitled to receive any
     rights in respect of the shares of Common Stock issuable upon conversion of
     the Securities as a result of the timing of the Conversion Date, the
     Conversion Rate will be adjusted as if the Company distributed to all
     holders of Common Stock Distributed Securities as provided in the first
     paragraph of clause (4) of this Subsection 4.06(a), subject to appropriate
     readjustment in the event of the expiration, termination or redemption of
     the Rights. Any distribution of rights or warrants pursuant to a Rights
     Plan complying with the requirements set forth in the immediately preceding
     sentence of this paragraph shall not constitute a distribution of rights or
     warrants pursuant to this Subsection 4.06(a). Other than as specified in
     this clause (5) of this Subsection 4.06(a), there will not be any
     adjustment to the Conversion Rate as the result of the issuance of any
     Rights, the distribution of separate certificates representing such Rights,
     the exercise or redemption of such Rights in accordance with any Rights
     Plan or the termination or invalidation of any Rights.

          (6)  Rights or warrants (other than Rights issued pursuant to a Rights
     Plan) 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
     (each a "Trigger Event"): (A) are deemed to be transferred with such shares
     of Common Stock; (B) are not exercisable; and (C) are also issued in
     respect of future issuances of Common Stock, shall be deemed not to have
     been distributed for purposes of this Section 4.06 (and no adjustment to
     the Conversion Rate under this Section 4.06 will be required) until the
     occurrence of the earliest Trigger Event, whereupon such rights and
     warrants shall be deemed to have been distributed and an appropriate
     adjustment (if any is required) to the Conversion Rate shall be made under
     this Subsection. If any such right or warrant, including any such existing
     rights or warrants distributed prior to the date of this Indenture, are
     subject to events, upon the occurrence of which such rights or warrants
     become exercisable to purchase different securities, evidences of
     indebtedness or other assets, then the date of the occurrence of any and
     each such event shall be deemed to be the date of distribution and record
     date with respect to new rights or warrants with such rights (and a
     termination or expiration of the existing rights or warrants without
     exercise by any of the holders thereof). In addition, in the event of any
     distribution (or deemed distribution) of rights or warrants, or any Trigger
     Event or other event (of the type described in the preceding sentence) with
     respect thereto that was counted for purposes of calculating a distribution
     amount for which an adjustment to the Conversion Rate under this Section
     4.06 was made, (x) in the case of any such rights or warrants which shall
     all have been redeemed, purchased by the Company or purchased without
     exercise by any holders thereof, the Conversion Rate shall be readjusted
     upon such final redemption, purchase by the Company or purchase without
     exercise 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 purchase price received by a holder or holders 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 purchase, and (y) in the case of such
     rights or warrants which shall have expired or been terminated without
     exercise by any holders thereof, the Conversion Rate shall be readjusted as
     if such rights and warrants had not been issued.

          (7)  In case the Company shall, by dividend or otherwise, at any time
     distribute (a "Triggering Distribution") to all holders of its Common Stock
     cash (excluding any dividend or distribution in connection with the
     liquidation, dissolution or winding up of the Company, whether voluntary or
     involuntary) the Conversion Rate shall be increased so that the same shall

                                       37

<PAGE>

     equal the rate determined by multiplying such Conversion Rate in effect
     immediately prior to the day on which such Triggering Distribution is
     declared ("Determination Date") by a fraction of which the numerator shall
     be such Current Market Price per share of the Common Stock on the
     Determination Date and the denominator of which shall be the Current Market
     Price per share of the Common Stock on the Determination Date less the
     amount of cash dividend or distribution, applicable to one share of Common
     Stock (determined on the basis of the number of shares of Common Stock
     outstanding at the close of business on the Determination Date), such
     increase to become effective immediately prior to the opening of business
     on the day following the date on which the Triggering Distribution is paid.

          (8)  In case any tender offer made by the Company or any of its
     Subsidiaries for all or any portion of Common Stock shall expire, then, if
     the tender offer shall require the payment to shareholders of consideration
     per share of Common Stock having a fair market value (determined as
     provided below) that exceeds the average of the Closing Price per share of
     Common Stock for each of the ten consecutive Trading Days next succeeding
     the Expiration Date (as defined below), immediately prior to the opening of
     business on the day after the last date (the "Expiration Date") tenders
     could have been made pursuant to such tender offer (as it may be amended)
     (the last time at which such tenders could have been made on the Expiration
     Date is hereinafter sometimes called the "Expiration Time"), the Conversion
     Rate shall be increased so that the same shall equal the rate determined by
     multiplying the Conversion Rate in effect immediately prior to the close of
     business on the Expiration Date by a fraction of which the numerator shall
     be the sum of (A) the fair market value of the aggregate consideration (the
     fair market value as determined by the Board of Directors, whose
     determination shall be conclusive evidence of such fair market value and
     which shall be evidenced by an Officers Certificate delivered to the
     Trustee) payable to shareholders based on the acceptance (up to any maximum
     specified in the terms of the tender offer) 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") and
     (B) the product of the number of shares of Common Stock outstanding (less
     any Purchased Shares and excluding any shares held in the treasury of the
     Company) at the Expiration Time and the average Closing Price per share of
     Common Stock for each of the ten consecutive Trading Days next succeeding
     the Expiration Date and the denominator of which shall be the product of
     the number of shares of Common Stock outstanding (including Purchased
     Shares but excluding any shares held in the treasury of the Company) at the
     Expiration Time multiplied by the average of the Closing Price per share of
     the Common Stock for each of the ten consecutive Trading Days next
     succeeding the Expiration Date, such increase to become effective
     immediately prior to the opening of business on the day following the
     Expiration Date. In the event that the Company is obligated to purchase
     shares pursuant to any such tender offer, but the Company is permanently
     prevented by applicable law from effecting any or all such purchases or any
     or all such purchases are rescinded, the Conversion Rate shall again be
     adjusted to be the Conversion Rate which would have been in effect based
     upon the number of shares actually purchased. If the application of this
     clause (8) of Subsection 4.06(a) to any tender offer would result in a
     decrease in the Conversion Rate, no adjustment shall be made for such
     tender offer under this clause (8).

          (9)  For purposes of this Subsection, the term "tender offer" shall
     mean and include both tender offers and exchange offers, all references to
     "purchases" of shares in tender offers (and all similar references) shall
     mean and include both the purchase of shares in tender offers and the
     acquisition of shares pursuant to exchange offers, and all references to
     "tendered shares" (and all similar references) shall mean and include
     shares tendered in both tender offers and exchange offers.

                                       38

<PAGE>

          (10) For the purpose of any computation under this Subsection 4.06(a),
     the current market price (the "Current Market Price") per share of Common
     Stock on any date shall be deemed to be the average of the Closing Prices
     for the ten consecutive Trading Days ending on the earlier of (A) the
     Determination Date or the Expiration Date, as the case may be, with respect
     to distributions or tender offers under this Subsection 4.06(a) or (B) the
     "ex-date" with respect to distributions, issuances or other events
     requiring such computation under this Section 4.06. The closing price (the
     "Closing Price") of our Common Stock on any Trading Day shall be the last
     reported sales price or, in case no such sales price is reported on such
     date, the average of the reported closing bid and ask prices per share (or,
     if more than one in either case, the average of the average bid and the
     average ask prices per share), in either case on the NASDAQ National Market
     or, if the Common Stock is not listed or admitted to trading on the NASDAQ
     National Market, on the principal national securities exchange on which the
     Common Stock is listed or admitted to trading or, if not listed or admitted
     to trading on the NASDAQ National Market or any national securities
     exchange, or any comparable system, the closing sales price or, in case no
     reported sale takes place, the average of the closing bid and asked prices,
     as furnished by any two members of the National Association of Securities
     Dealers, Inc. selected from time to time by the Company for that purpose.
     If no such prices are available, the Current Market Price per share shall
     be the fair value of a share of Common Stock as reasonably determined by
     the Board of Directors (which determination shall be conclusive and shall
     be evidenced by an Officers' Certificate delivered to the Trustee). The
     "ex-date" shall mean the first date on which the Common Stock trades on the
     applicable exchange or in the applicable market, regular way, without the
     right to receive such issuance or distribution.

     (b)  In any case in which this Section 4.06 shall require that an
adjustment be made following a record date, a Determination Date or Expiration
Date, as the case may be, established for the purposes specified in this Section
4.06, the Company may elect to defer (but only until five Business Days
following the filing by the Company with the Trustee of the certificate
described in Section 4.09) issuing to the Holder of any Security converted after
such record date, Determination Date or Expiration Date the shares of Common
Stock and other capital stock of the Company issuable upon such conversion over
and above the shares of Common Stock and other capital stock of the Company (or
other cash, property or securities, as applicable) issuable upon such conversion
only on the basis of the Conversion Rate prior to adjustment; and, in lieu of
any cash, property or securities the issuance of which is so deferred, the
Company shall issue or cause its transfer agents to issue due bills or other
appropriate evidence prepared by the Company of the right to receive such cash,
property or securities. If any distribution in respect of which an adjustment to
the Conversion Rate is required to be made as of the record date, Determination
Date or Expiration Date therefor is not thereafter made or paid by the Company
for any reason, the Conversion Rate shall be readjusted to the Conversion Rate
which would then be in effect if such record date had not been fixed or such
effective date, Determination Date or Expiration Date had not occurred.

     (c)  For purposes of this Section 4.06, "record date" shall mean, with
respect to any dividend, distribution or other transaction or event in which the
holders of Common Stock have the right to receive any cash, securities or other
property or in which the Common Stock (or other applicable security) is
exchanged or converted into any combination of cash, securities or other
property, the date fixed for determination of shareholders entitled to receive
such cash, security or other property (whether or not such date is fixed by the
Board of Directors or by statute, contract or otherwise).

     (d)  If one or more event occurs requiring an adjustment be made to the
Conversion Rate for a particular period, adjustments to the Conversion Rate
shall be determined by the Company's Board of Directors to reflect the combined
impact of such Conversion Rate adjustment events, as set out in this Section
4.07, during such period.

     Section 4.07  No Adjustment.

     (a)  No adjustment in the Conversion Rate shall be required if Holders may
participate in the transactions set forth in Section 4.06 above (to the same
extent as if the Securities had been converted into Common Stock immediately
prior to such transactions) without converting the Securities held by such
Holders.

     (b)  No adjustment in the Conversion Rate shall be required unless such
adjustment would require an increase or decrease of at least 1% in the
Conversion Rate as last adjusted; provided, however, that any adjustments which
would be required to be made but for this Section 4.07(b) shall be carried
forward and taken into account in any subsequent adjustment. All calculations
under this Article 4 shall be made to the nearest cent or to the nearest
one-hundredth of a share, as the case may be, with one half cent and 0.005 of a
share, respectively, being rounded upward.

     (c)  No adjustment in the Conversion Rate shall be required for issuances
of Common Stock pursuant to a Company plan for reinvestment of dividends or
interest or for a change in the par value or a change to no par value of the
Common Stock.

     (d)  To the extent that the Securities become convertible into the right to
receive cash, no adjustment need be made thereafter as to the cash.

     Section 4.08  Adjustment For Tax Purposes.

     The Company shall be entitled to make such increases in the Conversion
Rate, in addition to those required by Section 4.06, as it in its discretion
shall determine to be advisable in order that any stock dividends, subdivisions
of shares, distributions of rights to purchase stock or securities or
distributions of securities convertible into or exchangeable for stock hereafter
made by the Company to its shareholders shall not be taxable or that the tax
resulting from such transaction be diminished. Any such change in the Conversion
Rate shall also be made to the Conversion Price.

     Section 4.09  Notice Of Adjustment.

     Whenever the Conversion Rate or conversion privilege is required to be
adjusted pursuant to this Indenture, the Company shall promptly mail to Holders
a notice of the adjustment and file with the Trustee an Officers' Certificate
briefly stating the facts requiring the adjustment and the manner of computing
it. Failure to mail such notice or any defect therein shall not affect the
validity of any such adjustment. Unless and until the Trustee shall receive an
Officers' Certificate setting forth an adjustment of the Conversion Rate, the
Trustee may assume without inquiry that the Conversion Rate has not been
adjusted and that the last Conversion Rate of which it has knowledge remains in
effect.

     Section 4.10  Notice Of Certain Transactions.

     In the event that:

     (a)  the Company takes any action which would require an adjustment in the
Conversion Rate;

     (b)  the Company consolidates or merges with, or transfers all or
substantially all of its property and assets to, another corporation and
shareholders of the Company must approve the transaction; or

                                       40

<PAGE>

     (c)  there is a dissolution or liquidation of the Company,

the Company shall mail to Holders and file with the Trustee a notice stating the
proposed record date or effective date, as the case may be. The Company shall
mail such notice at least 10 days before such proposed record date or effective
date. Failure to mail such notice or any defect therein shall not affect the
validity of any transaction referred to in clause (a), (b) or (c) of this
Section 4.10.

     Section 4.11  Effect Of Reclassification, Consolidation, Merger Or Sale On
Conversion Privilege.

     (a)  If any of the following shall occur, namely: (1) any reclassification
or change of shares of Common Stock issuable upon conversion of the Securities
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination or any
other transaction or event for which an adjustment is provided in Section 4.06);
(2) any statutory share exchange, consolidation or merger or combination to
which the Company is a party other than a merger in which the Company is the
continuing corporation and which does not result in any reclassification of, or
change (other than in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination) in,
outstanding shares of Common Stock; or (3) any sale or conveyance of all or
substantially all the property and assets of the Company, directly or
indirectly, to any person, then the Company and any such successor, purchasing
or transferee corporation, as the case may be, shall, as a condition precedent
to such reclassification, change, combination, statutory share exchange,
consolidation, merger, sale or conveyance, execute and deliver to the Trustee a
supplemental indenture to this Indenture providing that the Holder of each
Security then outstanding shall have the right to convert such Security into the
kind and amount of shares of stock and other securities and property (including
cash) receivable upon such reclassification, change, combination, statutory
share exchange, consolidation, merger, sale or conveyance by a holder of the
number of shares of Common Stock deliverable upon conversion of such Security
immediately prior to such reclassification, change, combination, statutory share
exchange, consolidation, merger, sale or conveyance (assuming such holder of
Common Stock did not exercise any right of election as to the kind or amount of
stock, other securities or other property or assets, including cash, receivable
upon such transaction, and provided that if the kind or amount of stock, other
securities or other property or assets receivable upon such transaction is not
the same for each share of Common Stock in respect of which such rights of
election shall not have been exercised, then the kind and amount shall be deemed
to be the kind and amount receivable per share of Common Stock by a plurality of
the nonelecting shares). Such supplemental indenture shall provide for
adjustments of the Conversion Rate which shall be as nearly equivalent as may be
practicable to the adjustments of the Conversion Rate provided for in this
Article 4. If, in the case of any such consolidation, merger, combination,
statutory share exchange, sale or conveyance, the stock or other securities and
property (including cash) receivable thereupon by a holder of Common Stock
include shares of stock or other securities and property of a person other than
the successor, purchasing or transferee corporation, as the case may be, in such
consolidation, merger, combination, statutory share exchange, sale or
conveyance, then such supplemental indenture shall also be executed by such
other person and shall contain such additional provisions to protect the
interests of the Holders of the Securities as the Board of Directors shall
reasonably consider necessary by reason of the foregoing. The provisions of this
Section 4.11 shall similarly apply to successive reclassifications, changes,
combinations, consolidations, mergers, sales or conveyances.

     (b)  In the event the Company shall execute a supplemental indenture
pursuant to this Section 4.11, the Company shall promptly file with the Trustee
(1) an Officers' Certificate briefly stating the reasons therefor, the kind or
amount of shares of stock or other securities or property (including cash)
receivable by Holders of the Securities upon the conversion of their Securities
after any such reclassification, change, combination, consolidation, merger,
sale or conveyance, any adjustment to be

                                       41

<PAGE>

made with respect thereto and that all conditions precedent have been complied
with and (2) an Opinion of Counsel that all conditions precedent thereto and
hereunder have been complied with, and shall promptly mail notice thereof to all
Holders. Failure to mail such notice or any defect therein shall not affect the
validity of such transaction and such supplemental indenture.

     Section 4.12  Trustee's Disclaimer.

     (a)  The Trustee shall have no duty to determine when an adjustment under
this Article 4 should be made, how it should be made or what such adjustment
should be, but may accept as conclusive evidence of that fact or the correctness
of any such adjustment, and shall be protected in relying upon, an Officers'
Certificate and Opinion of Counsel, including the Officers' Certificate with
respect thereto which the Company is obligated to file with the Trustee pursuant
to Section 4.09. The Trustee makes no representation as to the validity or value
of any securities or assets issued upon conversion of Securities, and the
Trustee shall not be responsible for the Company's failure to comply with any
provisions of this Article 4.

     (b)  The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 4.11, but may accept as conclusive evidence of the
correctness thereof, and shall be fully protected in relying upon, the Officers'
Certificate and Opinion of Counsel, with respect thereto which the Company is
obligated to file with the Trustee pursuant to Section 4.11.

     Section 4.13  Voluntary Increase.

     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 20 days, the increase is
irrevocable during the period and the Board of Directors determines that such
increase would be in the best interests of the Company or to avoid or diminish
income tax to holders of shares of Common Stock in connection with a dividend or
distribution of stock or similar event, and the Company provides 15 days' prior
written notice of any increase in the Conversion Rate; provided, however, that
in no event may the Company increase the Conversion Rate so that the adjusted
Conversion Price would be less than the par value of a share of Common Stock.
Any such change in the Conversion Rate shall also be made to the Conversion
Price.

     Section 4.14  Payment of Cash in Lieu of Common Stock

     (a)  In lieu of delivery of some or all of the shares of Common Stock
otherwise issuable upon notice of conversion of any Securities, the Company may
elect to pay Holders surrendering Securities for conversion an amount in cash
per $1,000 Principal Amount at Maturity of Securities determined as provided in
this Section 4.14.

     (b)  The amount payable per $1,000 Principal Amount at Maturity of
Securities will be the amount equal to the average Closing Price per share of
Common Stock for the five consecutive Trading Days during the cash averaging
period multiplied by the Conversion Rate. The "cash averaging period" means the
five consecutive Trading Days immediately following (i) the date of the
Company's notice pursuant to clause (c) below, (ii) the Conversion Date, in the
case of conversion following the Company's notice of redemption specifying that
the Company intends to deliver cash upon conversion or (iii) the Final Maturity
Date. If the Company elects to satisfy only part of its obligation to deliver
shares of Common Stock upon conversion of Securities with cash, it shall specify
a number of shares of Common Stock per $1,000 Principal Amount at Maturity as to
which it will deliver cash and the amount of cash to be delivered will be
determined as provided above except that the average Closing Price per share of

                                       42

<PAGE>
Common Stock shall be multiplied by that number of shares as to which the
Company has elected to deliver cash.

     (c)  The Company will inform the Holders through the Trustee no later than
two Business Days following the Conversion Date of its election to deliver
shares of Common Stock or to pay cash in lieu of delivery of some or all of such
shares, unless it has already informed Holders of its election in connection
with a notice of redemption.

     (d)  If an Event of Default (other than a default in a cash payment upon
conversion of Securities) has occurred and is continuing, the Company may not
pay cash upon conversion of any Securities or portion of the Securities (other
than cash in lieu of fractional shares pursuant to Section 4.03).

                                    COVENANTS

     Section 6.01  Payment Of Securities.

     (a)  The Company shall promptly make all payments in respect of the
Securities on the dates and in the manner provided in the Securities and this
Indenture. An installment of principal or interest or Liquidated Damages, if
any, shall be considered paid on the date it is due if the Paying Agent (other
than the Company) holds by 11:00 a.m., New York City time, on that date money,
deposited by or on behalf of the Company sufficient to pay the installment.
Subject to Section 4.02 hereof, accrued and unpaid interest on any Security that
is payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security is registered at
the close of business on the Regular Record Date for such interest at the office
or agency of the Company maintained for such purpose. Principal Amount at
Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price,
Put Right Purchase Price, Change of Control Purchase Price, and cash interest
shall be considered paid on the applicable date due if on such date (or, in the
case of Put Right Purchase Price or Change of Control Purchase Price, on the
Business Day following the applicable Put Right Purchase Date or Change of
Control Purchase Date, as the case may be) the Trustee or the Paying Agent
holds, in accordance with this Indenture, money, sufficient to pay all such
amounts then due. The Company shall, to the fullest extent permitted by law, pay
cash interest in immediately available funds on overdue principal (including
premium, if any) and overdue installments of interest at the rate borne by the
Securities compounded semiannually, which interest shall accrue from the date
such overdue amount was originally due to the date payment of such amount,
including interest thereon, has been made or duly provided for. All such
interest shall be payable on demand. The accrual of such interest on overdue
amounts shall be in lieu of, and not in addition to, the continued accrual of
Original Issue Discount.

     (b)  Payment of the principal of (and premium, if any) and interest on the
Securities shall be made at the office or agency of the Company maintained for
that purpose in the Borough of Manhattan, The City of New York (which shall
initially be the Trustee) or at the Corporate Trust Office of the Trustee in

is legal tender for payment of public and private debts; provided, however, that
at the option of the Company payment of interest may be made by check mailed to
the address of the Person entitled thereto as such address appears in the
Register; provided further that a Holder with an aggregate Principal Amount at
Maturity in

                                       43

<PAGE>

excess of $2,000,000 will be paid by wire transfer in immediately available
funds at the election of such Holder if such Holder has provided wire transfer
instructions to the Trustee at least 10 Business Days prior to the payment date.
Any wire transfer instructions received by the Trustee will remain in effect
until revoked by the Holder.

     Section 6.02  SEC and Other Reports.

     (a)  The Company shall file all reports and other information and documents
which it is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act, and within 15 days after it files them with the SEC, the Company
shall file copies of all such reports, information and other documents with the
Trustee; provided that any such reports, information and documents filed with
the SEC pursuant to its Electronic Data Gathering, Analysis and Retrieval system
shall be deemed to be filed with the Trustee. The Company also shall comply with
the provisions of TIA Section 314(a).

     (b)  Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     Section 6.03  Compliance Certificates.

     The Company shall deliver to the Trustee, within 90 days after the end of
each fiscal year of the Company (beginning with the fiscal year ending December
31, 2004), an Officers' Certificate as to the signer's knowledge of the
Company's compliance with all conditions and covenants on its part contained in
this Indenture and stating whether or not the signer knows of any default or
Event of Default. If such signer knows of such a default or Event of Default,
the Officers' Certificate shall describe the default or Event of Default and the
efforts to remedy the same. For the purposes of this Section 6.03, compliance
shall be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

     Section 6.04  Further Instruments And Acts.

     Upon request of the Trustee, the Company will execute and deliver such
further instruments and do such further acts as may be reasonably necessary or
proper to carry out more effectively the purposes of this Indenture.

     Subject to Article 7, the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence.

     Section 6.06  Rule 144A Information Requirement.

     Within the period prior to the expiration of the holding period applicable
to sales thereof under Rule 144(k) under the Securities Act (or any successor
provision), the Company covenants and agrees that it shall, during any period in
which it is not subject to Section 13 or 15(d) under the Exchange Act, upon the
request of any Holder or beneficial holder of the Securities make available to
such Holder or beneficial holder of Securities or any Common Stock issued upon
conversion thereof which continue to be Restricted Securities in connection with
any sale thereof and any prospective purchaser of Securities or such Common
Stock designated by such Holder or beneficial holder, the information required
pursuant to

                                       44

<PAGE>

Rule 144A(d)(4) under the Securities Act and it will take such further action as
any Holder or beneficial holder of such Securities or such Common Stock may
reasonably request, all to the extent required from time to time to enable such
Holder or beneficial holder to sell its Securities or Common Stock without
registration under the Securities Act within the limitation of the exemption
provided by Rule 144A, as such Rule may be amended from time to time. Whether a
person is a beneficial holder shall be determined by the Company.

     Section 6.07  Stay, Extension And Usury Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law or other law
which would prohibit or forgive the Company from paying all or any portion of
the principal of, premium, if any, or interest (including Liquidated Damages, if
any), on the Securities as contemplated herein, wherever enacted, now or at any
time hereafter in force, or which may affect the covenants or the performance of
this Indenture, and the Company (to the extent it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law and covenants that it
will not, by resort to any such law, hinder, delay or impede the execution of
any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

     Section 6.08  Payment Of Liquidated Damages.

     If Liquidated Damages are payable by the Company pursuant to the
Registration Rights Agreement, the Company shall deliver to the Trustee a
certificate to that effect stating (i) the amount of such Liquidated Damages
that are payable, (ii) the reason why such Liquidated Damages are payable and
(iii) the date on which such Liquidated Damages are payable. Unless and until a
Trust Officer of the Trustee receives such a certificate, the Trustee may assume
without inquiry that no such Liquidated Damages is payable. If the Company has
paid Liquidated Damages directly to the Persons entitled to such Liquidated
Damages, the Company shall deliver to the Trustee a certificate setting forth
the particulars of such payment.

     Section 6.09  Maintenance of Office or Agency.

     The Company will maintain an office or agency of the Trustee, Registrar and
Paying Agent where Securities may be presented or surrendered for payment, where
Securities may be surrendered for registration of transfer, purchase or
redemption and where notices and demands to or upon the company in respect of
the Securities and this Indenture may be served. The office of the Trustee,
located at Sixth Street & Marquette Avenue, Minneapolis, MN 55479 (Attention:
Corporate Trust Services), shall initially be such office or agency for all of
the aforesaid purposes. The Company shall give prompt written notice to the
Trustee of the location, and of any change in the location, of any such office
or agency (other than a change in the location of the office of the Trustee). If
at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
address of the Trustee set forth in Section 14.02.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency.

     Section 8.01  Events Of Default.

     (a)  An "Event of Default" shall occur if:

     now exists or shall hereafter be created, or there is an acceleration of
     indebtedness for borrowed money in an amount in excess of $10,000,000
     because of a default with respect to such indebtedness, and such

               (B)  consents to the entry of an order for relief against it in
          an involuntary case or proceeding or the commencement of any case
          against it;

               (C)  consents to the appointment of a Custodian of it or for all
          or substantially all of its property;

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

               (F)  consents to the filing of such a petition or the appointment
          of or taking possession by a Custodian;

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

               (A)  is for relief against the Company or any Significant
          Subsidiary of the Company in an involuntary case or proceeding or

          insolvent or bankrupt;

               (B)  appoints a Custodian of the Company or any Significant

     or

          (9)  default in delivery when due of all cash and shares of Common
     Stock deliverable upon conversion of the Securities, which default
     continues for 15 days.

The term "Bankruptcy Law" means Title 11 of the United States Code (or any
successor thereto) or any similar federal or state law for the relief of
debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator,
sequestrator or similar official under any Bankruptcy Law.

     (b)  A default under clauses (3), (4) or (5) of Subsection 8.01(a) is not
an Event of Default until the Trustee notifies the Company in writing, or the
Holders of at least 25% in aggregate Principal Amount at Maturity of the
Securities then outstanding notify the Company and the Trustee, in writing of
the default, and the Company does not cure the default within the time specified
in clauses (3), (4) or (5) of Subsection 8.01(a) after receipt of such notice. A
notice given pursuant to this Section 8.01 shall be given by registered or
certified mail, must specify the default, demand that it be remedied and state
that the notice is a Notice of Default. When any default under this Section 8.01
is cured, it ceases.

     (c)  The Company will deliver to the Trustee, within 5 Business Days of
becoming aware of the occurrence of an Event of Default, written notice thereof.
In addition, the Company shall deliver to the Trustee, within 10 days after it
becomes aware of the occurrence thereof, written notice of any event

                                       48

<PAGE>

which with the lapse of time would become an Event of Default under clause (3),
(4) or (5) of Subsection 8.01(a).

     The Trustee shall not be charged with knowledge of any Event of Default
unless written notice thereof shall have been given to a Trust Officer at the
Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder
or any agent of any Holder or unless it acquires actual knowledge of such Event
of Default in the course of performing other duties pursuant to this Indenture.

     Section 8.02  Acceleration.

     If an Event of Default (other than an Event of Default specified in clause
(6) or (7) of Subsection 8.01(a)) occurs and is continuing with respect to the
Company, the Trustee may, by notice to the Company, or the Holders of at least
25% in aggregate Principal Amount at Maturity of the Securities then outstanding
may, by notice to the Company and the Trustee, declare the Issue Price plus the
accrued Original Issue Discount and accrued and unpaid cash interest, if any,
and accrued and unpaid Liquidated Damages, if any, through the date of
declaration on all the Securities to be immediately due and payable. Upon such a
declaration, such Issue Price plus accrued Original Issue Discount, and such
accrued and unpaid cash interest, if any, and such accrued and unpaid Liquidated
Damages, if any, shall be due and payable immediately. If an Event of Default
specified in Section 8.01(6) or (7) occurs in respect of the Company and is
continuing, the Issue Price plus accrued Original Issue Discount and accrued and
unpaid cash interest, if any, and accrued and unpaid Liquidated Damages, if any,
on all the Securities shall become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Securityholders.
The Holders of a majority in aggregate Principal Amount at Maturity of the
Securities then outstanding by notice to the Trustee may rescind an acceleration
and its consequences if (a) all existing Events of Default, other than the
nonpayment of the principal of the Securities which has become due solely by
such declaration of acceleration, have been cured or waived; (b) to the extent
the payment of such interest is lawful, interest (calculated at the rate per
annum borne by the Securities) on overdue installments of interest and overdue
principal, which has become due otherwise than by such declaration of
acceleration, has been paid; (c) the rescission would not conflict with any
judgment or decree of a court of competent jurisdiction; and (d) all payments
due to the Trustee and any predecessor Trustee under Section 9.07 have been
made. No such rescission shall affect any subsequent default or impair any right
consequent thereto.

     Section 8.03  Other Remedies.

     (a)  If an Event of Default occurs and is continuing, the Trustee may, but
shall not be obligated to, pursue any available remedy by proceeding at law or
in equity to collect the payment of the Issue Price plus accrued Original Issue
Discount and unpaid cash interest, if any, accrued and unpaid Liquidated
Damages, if any, on the Securities or to enforce the performance of any
provision of the Securities or this Indenture.

     (b)  The Trustee may maintain a proceeding even if it does not possess any
of the Securities 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. No remedy is exclusive of any
other remedy. All available remedies are cumulative to the extent permitted by
law.

     Section 8.04  Waiver Of Defaults And Events Of Default.

     Subject to Sections 8.07 and 11.02, the Holders of a majority in aggregate
Principal Amount at Maturity of the Securities then outstanding by notice to the
Trustee may waive an existing default or

                                       49

<PAGE>

Event of Default and its consequences, except a default or Event of Default in
the payment of the principal of, premium, if any, or interest on any Security, a
failure by the Company to convert any Securities into Common Stock or any
default or Event of Default in respect of any provision of this Indenture or the
Securities which, under Section 11.02, cannot be modified or amended without the
consent of the Holder of each Security affected. When a default or Event of
Default is waived, it is cured and ceases.

     Section 8.05  Control By Majority.

     The Holders of a majority in aggregate Principal Amount at Maturity of the
Securities then outstanding may direct the time method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust
or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture, that the Trustee determines
may be unduly prejudicial to the rights of another Holder or the Trustee, or
that may involve the Trustee in personal liability unless the Trustee is offered
indemnity satisfactory to it; provided, however, that the Trustee may take any
other action deemed proper by the Trustee which is not inconsistent with such
direction.

     Section 8.06  Limitations On Suits.

     (a)  A Holder may not pursue any remedy with respect to this Indenture or
the Securities (except actions for payment of overdue principal, premium, if
any, or interest or for the conversion of the Securities pursuant to Article 4)
unless:

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

          (2)  the Holders of at least 25% in aggregate Principal Amount at
     Maturity of the then outstanding Securities make a written request to the
     Trustee to pursue the remedy;

          (3)  such Holder or Holders offer to the Trustee reasonable indemnity
     to the Trustee against any loss, liability or expense;

          (4)  the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of indemnity; and

          (5)  no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     in aggregate Principal Amount at Maturity of the Securities then
     outstanding.

     (b)  A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over such other
Securityholder.

     Section 8.07  Rights Of Holders To Receive Payment And To Convert.

     Notwithstanding any other provision of this Indenture, the right of any
Holder of a Security to receive payment of the Principal Amount at Maturity,
Issue Price plus accrued Original Issue Discount, Redemption Price, Put Right
Purchase Price, Change of Control Purchase Price, or cash interest in respect of
the Securities held by such Holder, on or after the respective due dates
expressed in the Securities and this Indenture, to convert such Security in
accordance with Article 4 and to bring suit for the enforcement of any such
payment on or after such respective dates or the right to convert, is absolute
and unconditional and shall not be impaired or affected without the consent of
the Holder.

     Section 8.08  Collection Suit By Trustee.

     If an Event of Default described in clause (1) or (2) of Subsection 8.01(a)
occurs and is continuing, the Trustee may recover judgment in its own name and
as trustee of an express trust against the Company or another obligor on the
Securities for the whole amount owing with respect to the Securities 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.

     Section 8.09  Trustee May File Proofs Of Claim.

     The Trustee may 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 on the
Securities), its creditors or its property and shall be entitled and empowered
to collect and receive any money or other property payable or deliverable on any
such claims and to distribute the same, 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 9.07, and to the extent that such payment of the reasonable
compensation, expenses, disbursements and advances in any such proceedings 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 property which the Holders may be entitled to receive in such
proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to, or, on behalf of any Holder, to
authorize, accept or adopt any plan of reorganization, arrangement, adjustment
or composition affecting the Securities or the rights of any Holder thereof, or
to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding.

     Section 8.10  Priorities.

     (a)  If the Trustee collects any money pursuant to this Article 8, it shall
pay out the money in the following order:

          (1)  First, to the Trustee for amounts due under Section 9.07;

          (2)  Second, to the holders of Senior Indebtedness to the extent

     payable on the Securities (including Liquidated Damages, if any),
     respectively;

          (4)  Fourth, to such other Person or Persons, if any, to the extent
     entitled thereto; and

     Section 8.11  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
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 8.11 does not apply to a suit made by the Trustee, a suit by a Holder
pursuant to Section 8.07, or a suit by Holders of more than 10% in aggregate
Principal Amount at Maturity of the Securities then outstanding. This Section
8.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is
hereby expressly excluded from this Indenture, as permitted by the TIA.

                                   ARTICLE IX

                                     TRUSTEE

     Section 9.01  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 his or her own
affairs.

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

          (1)  the Trustee need perform only those duties as are specifically
     set forth in this Indenture and no others; and

          (2)  in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. The
     Trustee, however, shall examine any certificates and opinions which by any
     provision hereof are specifically required to be delivered to the Trustee
     to determine whether or not they conform to the requirements of this
     Indenture, but need not confirm or investigate the accuracy of mathematical
     calculations or other facts stated therein.

          This Section 9.01(b) shall be in lieu of Section 315(a) of the TIA and
     such Section 315(a) is hereby expressly excluded from this Indenture, as
     permitted by the TIA.

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

          (1)  this paragraph does not limit the effect of Subsection (b) of
     this Section 9.01;

          (2)  the Trustee shall not be liable for any error of judgment made in
     good faith by a Trust Officer, unless it is proved that the Trustee was

<PAGE>

          (3)  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

          This Section 9.01(c) shall be in lieu of Sections 315(d)(1), 315(d)(2)
     and 315(d)(3) of the TIA and such Sections are hereby expressly excluded
     from this Indenture as permitted by the TIA.

     (d)  No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder or in the exercise of any of its rights or powers
unless the Trustee shall have received adequate indemnity in its opinion against
potential costs and liabilities incurred by it relating thereto.

     (e)  Every provision of this Indenture that in any way relates to the
Trustee is subject to Subsections (a), (b), (c) and (d) of this Section 9.01.

it except as the Trustee may agree in writing with the Company. Money held in

     (a)  Subject to Section 9.01:

          (1)  The Trustee may rely conclusively on any document believed by it
     to be genuine and to have been signed or presented by the proper person.
     The Trustee need not investigate any fact or matter stated in the document.

          (2)  Before the Trustee acts or refrains from acting, it may require
     an Officers' Certificate or an Opinion of Counsel, which shall conform to
     Section 12.04(b). 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.

          (3)  The Trustee may act through its agents and shall not be
     responsible for the misconduct or negligence of any agent appointed with
     due care.

          (4)  The Trustee shall not be liable for any action it takes or omits
     to take in good faith which it believes to be authorized or within its
     rights or powers.

          (5)  The Trustee may consult with counsel of its selection, and the
     advice or opinion of such counsel as to matters of law shall be full and

     the advice or opinion of such counsel.

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

          (7)  The Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request,

                                       53

<PAGE>

     direction, consent, order, bond, debenture, note, other evidence of
     indebtedness or other paper or document, but the Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit, and, if the Trustee shall determine to make
     such further inquiry or investigation, it shall be entitled to examine the
     books, records and premises of the Company, personally or by agent or
     attorney at the sole cost of the Company, and shall incur no liability or
     additional liability of any kind by reason of such inquiry or
     investigation.

          (8)  The Trustee shall not be deemed to have notice of any default or
     Event of Default unless a Trust Officer of the Trustee has actual knowledge
     thereof or unless written notice of any event which is in fact such a
     default is received by the Trustee at the Corporate Trust Office, and such
     notice references the Securities and this Indenture.

          (9)  The rights, privileges, protections, immunities and benefits
     given to the Trustee, including, without limitation, its right to be
     indemnified, are extended to, and shall be enforceable by, the Trustee in
     each of its capacities hereunder, including, without limitation as Paying
     Agent, Registrar and Conversion Agent, and to each agent, custodian and
     other Person employed to act hereunder.

     Section 9.03  Individual Rights Of Trustee.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Company or an Affiliate of
the Company with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. However, the Trustee is subject to Sections
9.10 and 9.11.

     Section 9.04  Trustee's Disclaimer.

     The Trustee makes no representation as to the validity or adequacy of this
Indenture, the Securities, the Pledge Agreement, or the Pledged Securities. It
shall not be accountable for the Company's use of the proceeds from the
Securities and it shall not be responsible for any statement in the Securities
other than its certificate of authentication.

     Section 9.05  Notice Of Default Or Events Of Default.

     If a default or an Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to each Securityholder notice of
all uncured defaults or Events of Default known to it within 90 days after it
occurs or, if later, within 15 days after it becomes known to the Trustee.
However, the Trustee may withhold the notice if and so long as a committee of
its Trust Officers in good faith determines that withholding notice is in the
interests of Securityholders, except in the case of a default or an Event of
Default in payment of the principal of, or premium, if any, or interest on any
Security when due or in the payment of any redemption or purchase obligation.
This Section 9.05 is in lieu of section 315(b) of the TIA and such provision is
expressly excluded from this Indenture as permitted by the TIA.

     Section 9.06  Reports By Trustee To Holders.

     (a)  If a report is required by TIA Section 313, within 60 days after each

January 31 that complies with TIA Section 313(a). The Trustee also shall comply
with TIA Section 313(b)(2) and (c).

     (b)  A copy of each report at the time of its mailing to Securityholders
shall be mailed to the Company and, to the extent required by the TIA, filed
with the SEC, and each stock exchange, if any, on which the Securities are

listed on any stock exchange or listed or admitted to trading on any quotation
system and any changes in the stock exchanges or quotation systems on which the
Securities are listed or admitted to trading and of any delisting thereof.

     Section 9.07  Compensation And Indemnity.

     (a)  The Company shall pay to the Trustee from time to time such
compensation (as agreed to from time to time by the Company and the Trustee in
writing) for its services (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust). The Company shall reimburse the Trustee upon request for all reasonable
disbursements, expenses and advances incurred or made by it. Such expenses may
include the reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel.

     (b)  The Company shall indemnify the Trustee or any predecessor Trustee
(which for purposes of this Section 9.07 shall include its officers, directors,
employees and agents) for, and hold it harmless against, any and all loss,
liability or expense including taxes (other than taxes based upon, measured by
or determined by the income of the Trustee), incurred by it in connection with
the acceptance or administration of its duties under this Indenture or any
action or failure to act as authorized or within the discretion or rights or
powers conferred upon the Trustee hereunder including the reasonable costs and
expenses of the Trustee and its counsel in defending (including reasonable legal
fees and expenses) itself against any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder. The Trustee
shall notify the Company promptly of any claim asserted against the Trustee for
which it may seek indemnity. The Company need not pay for any settlement
effected without its prior written consent, which shall not be unreasonably
withheld.

     (c)  The Company need not reimburse the Trustee for any expense or
indemnify it against any loss or liability incurred by it resulting from its
gross negligence or bad faith.

     (d)  To secure the Company's payment obligations in this Section 9.07, the
Trustee shall have a senior claim to which the Securities are hereby made
subordinate on all money or property held or collected by the Trustee, except
for the Pledged Securities and such money or property held in trust to pay the
principal of and interest on particular Securities. The obligations of the
Company under this Section 9.07 shall survive the satisfaction and discharge of
this Indenture or the resignation or removal of the Trustee.

     (e)  When the Trustee incurs expenses or renders services after an Event of
Default specified in clause (6) or (7) of Subsection 8.01(a) occurs, the
expenses and the compensation for the services are intended to constitute
expenses of administration under any Bankruptcy Law. The provisions of this
Section shall survive the termination of this Indenture.

     Section 9.08  Replacement Of Trustee.

     (a)  The Trustee may resign by so notifying the Company. The Holders of a
majority in aggregate Principal Amount at Maturity of the Securities then
outstanding may remove the Trustee by so notifying the Trustee and the Company
and may, with the Company's written consent, appoint a successor Trustee. The
Company may remove the Trustee if:

          (1)  the Trustee fails to comply with Section 9.10;

                                       55

<PAGE>

          (2)  the Trustee is adjudged a bankrupt or an insolvent;

          (3)  a receiver or other public officer takes charge of the Trustee or
     its property; or

          (4)  the Trustee becomes incapable of acting.

     (b)  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. The resignation or removal of a Trustee shall not be effective until a
successor Trustee shall have delivered the written acceptance of its appointment
as described below.

     (c)  If a successor Trustee does not take office within 45 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of 10% in Principal Amount at Maturity of the Securities then
outstanding may petition any court of competent jurisdiction for the appointment
of a successor Trustee at the expense of the Company.

     (d)  If the Trustee fails to comply with Section 9.10, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

Company and each Holder.

     Section 10.01 Satisfaction And Discharge Of Indenture.

     (a)  (1) This Indenture shall cease to be of further effect (except as to
any surviving rights of conversion, registration of transfer or exchange of
Securities herein expressly provided for and except as further provided below),
and the Trustee, on demand of and at the expense of the Company, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture,
when either:

               (A)  all Securities theretofore authenticated and delivered
          (other than (i) Securities which have been destroyed, lost or stolen
          and which have been replaced or paid as provided in Section 2.07 and
          (ii) Securities for whose payment money has theretofore been deposited
          in trust and thereafter repaid to the Company as provided in Section
          10.03) have been delivered to the Trustee for cancellation; or

               (B)  all such Securities not theretofore delivered to the Trustee
          for cancellation,

                    (i)   have become due and payable,

                    (ii)  will become due and payable at the Final Maturity Date

                          arrangements reasonably satisfactory to the Trustee
                          for the giving of notice of redemption by the Trustee
                          in the name, and at the expense, of the Company;

          (2)  the Company has deposited with the Trustee or a Paying Agent
     (other than the Company or any of its Affiliates) as trust funds in trust
     for the purpose of and in an amount sufficient to pay and discharge the
     entire indebtedness on such Securities not theretofore delivered to the
     Trustee for cancellation, for principal and interest to the date of such
     deposit (in the case of Securities which have become due and payable) or to
     the Final Maturity Date or Redemption Date, as the case may be. In the
     event that the Company exercises its right to redeem the Securities as
     provided in Article 3, the Company shall have the right to withdraw its
     funds previously deposited with the Trustee or Paying Agent pursuant to the
     immediately preceding sentence;

          (3)  the Company has paid or caused to be paid all other sums payable

     and an Opinion of Counsel, each stating that all conditions precedent
     herein relating to the satisfaction and discharge of this Indenture have
     been complied with.

obligations of the Company with respect to the conversion privilege and the
Conversion Rate of the Securities pursuant to Article 4, the obligations of the
Company to the Trustee under Section 9.07 and, if money shall have been
deposited with the Trustee pursuant to clause (2) of Subsection 10.01(a), the
provisions of Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.12, 6.01 and 14.05,
Article 4, and this Article 10, shall survive until the Securities have been
paid in full.

     Section 10.02 Application Of Trust Money.

     Subject to the provisions of Section 10.03 and Section 13.05, the Trustee
or a Paying Agent shall hold in trust, for the benefit of the Holders, all money
deposited with it pursuant to Section 10.01 and shall apply the deposited money
in accordance with this Indenture and the Securities to the payment of the
principal of and interest on the Securities.

     Section 10.03 Repayment To Company.

     (a)  The Trustee and each Paying Agent shall promptly pay to the Company
upon request any excess money (1) deposited with them pursuant to Section 10.01
and (2) held by them at any time.

     (b)  The Trustee and each Paying Agent shall, subject to applicable
abandonment property laws, pay to the Company upon request any money held by
them for the payment of principal or interest that remains unclaimed for two
years after a right to such money has matured; provided, however, that the
Trustee or such Paying Agent, before being required to make any such payment,
may at the expense of the Company cause to be mailed to each Holder entitled to
such money notice that such money remains unclaimed and that after a date
specified therein, which shall be at least 30 days from the date of such
mailing, any unclaimed balance of such money then remaining will be repaid to
the Company. After payment to the Company, Holders entitled to money must look
to the Company for payment as general creditors unless an applicable abandoned
property law designates another person.

     Section 10.04 Reinstatement.

     (a)  If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 10.02 by reason of any legal proceeding or by reason of
any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, then the Company's
obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to Section 10.01 until
such time as the Trustee or such Paying Agent is permitted to apply all such
money in accordance with Section 10.02; provided, however, that if the Company
has made any payment of the principal of or interest on any Securities because
of the reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of such Securities to receive any such payment from the
money held by the Trustee or such Paying Agent.

     (b)  If pursuant to the last sentence of Section 10.01(2), the Company
withdraws its previously deposited funds as a result of its exercise of its
redemption right, the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit has occurred
pursuant to Section 10.01.

     that such modification or amendment does not, in the good faith opinion of

     the Holders in any material respect;

          (10) making any changes or modifications to this Indenture necessary
     in connection with the registration of the Securities under the Securities
     Act as contemplated by the Registration Rights Agreement, provided that
     this action does not adversely affect the interests of the Holders in any
     material respect; or

          (11) adding or modifying any other provisions which the Company and
     the Trustee may deem necessary or desirable and which will not adversely
     affect the interests of the Holders in any material respect.

the Securities with the written consent of the Holders of at least a majority in

of Holders by at least a majority in aggregate Principal Amount at Maturity of
the Securities represented at the meeting. However, notwithstanding the
foregoing but subject to Section 11.04, without the written consent of each
Holder affected, an amendment, supplement or waiver, including a waiver pursuant
to Section 8.04, may not:

          (1)  alter the manner of calculation or rate of accrual of Original

          (5)  make any change that adversely affects the rights of a Holder to
     convert any of the Securities;

          (6)  modify the Company's obligation to purchase Securities at the
     option of Holders or the Company's right to redeem Securities, in a manner
     adverse to the Holders;

          (7)  except as otherwise permitted pursuant to Article 7, consent to
     the assignment or transfer by the Company of any of its rights and
     obligations under this Indenture or the Securities;

          (8)  except as otherwise permitted or contemplated by provisions of
     this Indenture concerning corporate reorganizations, making any change to
     the purchase option of Holders upon a Change in Control (including
     changing, modifying or amending any definitions with respect thereto);

          (9)  impair the right to institute suit for the enforcement of any
     payment on or with respect to any Security or with respect to the
     conversion of any Security;

          (10) modify the provisions of this Indenture or the Pledge Agreement
     relating to the pledge of securities as contemplated under Article 12 in a

     waive any past default.

     (b)  The Holders of a majority in Principal Amount at Maturity of the
Securities then outstanding may, on behalf of all the Holders of all Securities,
waive compliance by the Company with the restrictive provisions of this
Indenture, and waive any past default under this Indenture and its consequences,
except a default in the payment of the Principal Amount at Maturity, accrued and
unpaid

                                       60

<PAGE>

cash interest, accrued and unpaid Liquidated Damages, accrued Original Issue
Discount, Redemption Price, Put Right Purchase Price or Change of Control
Purchase Price or in respect of any provision which under this Indenture cannot
be modified or amended without the consent of the Holder of each outstanding
security affected.

     (c)  After an amendment, supplement or waiver under this Section 11.02
becomes effective, the Company shall promptly mail to the Holders affected
thereby a notice briefly describing the amendment, supplement or waiver. 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 amendment,
supplement or waiver.

     Every amendment to or supplement of this Indenture or the Securities shall
comply with the TIA as in effect at the date of such amendment or supplement.

     Section 11.04 Revocation And Effect Of Consents.

     (a)  Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if notation of the consent is not made on
any Security. However, any such Holder or subsequent Holder may revoke the
consent as to its Security or portion of a Security if the Trustee receives the
notice of revocation before the date the amendment, supplement or waiver becomes
effective.

     (b)  After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder, unless it makes a change described in any of clauses
(1) through (12) of Subsection 11.02(a). In that case the amendment, supplement
or waiver shall bind each Holder of a Security who has consented to it and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security.

     Section 11.05 Notation On Or Exchange Of Securities.

     If an amendment, supplement or waiver changes the terms of a Security, the
Trustee may require the Holder of the Security to deliver it to the Trustee. The
Trustee may place an appropriate notation on the Security about the changed
terms and return it to the Holder. Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Security shall issue and the
Trustee shall authenticate a new Security that reflects the changed terms.

     Section 11.06 Trustee To Sign Amendments, Etc.

     The Trustee shall sign any amendment or supplemental indenture authorized
pursuant to this Article 11 if the amendment or supplemental indenture does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may, in its sole discretion, but need not sign it. In
signing or refusing to sign such amendment or supplemental indenture, the
Trustee shall be entitled to receive and, subject to Section 9.01, shall be
fully protected in relying upon, an Opinion of Counsel stating that such
amendment or supplemental indenture is authorized or permitted by this
Indenture. The Company may not sign an amendment or supplement indenture until
the Board of Directors approves it.

     Section 11.07 Effect Of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

                                   ARTICLE XII

                                    SECURITY

     Section 12.01 Security.

     (a)  At the Closing Time, the Company shall purchase and pledge to the
Trustee as security for the exclusive benefit of the Holders (and not for the
benefit of other creditors of the Company), the Initial Pledged Securities in
such amount as will be sufficient, upon receipt of scheduled interest and
principal payments of such Initial Pledged Securities, as computed by the
Company and verified for mathematical accuracy by KPMG LLP, independent public
accountants, or another nationally recognized firm of independent public
accountants selected by the Company, to provide for payment in full of the first
six scheduled interest payments (up to and including the interest payment due on
March 2, 2007), but excluding Liquidated Damages, if any, on the Securities when
due.

     (b)  The Initial Pledged Securities shall be pledged by the Company to the
Trustee for the exclusive benefit of the Holders and shall be held by the
Trustee in the Pledged Account. Immediately prior to each of the first six
scheduled Interest Payment Dates, the Trustee will release from the Pledged
Account proceeds sufficient to pay the interest then due on the Securities if
the Company has not made other provision for payment of such interest or if the
Company has requested that the Trustee do so. A failure to pay interest on the
Securities will constitute an event of default under this Indenture pursuant to
clause (2) of Subsection 8.01(a) herein; provided that, so long as the amount
released pursuant to the preceding sentence is sufficient to pay such interest,
the release of funds as provided shall not be deemed a failure to pay interest.

     (c)  The Initial Pledged Securities and the Pledged Account shall also
secure the repayment of the principal amount and Liquidated Damages, if any, on
the Securities only to the extent provided in the Pledge Agreement.

     (d)  On each relevant Date of Delivery (if such Date of Delivery is
different from the Closing Time), the Company shall (1) enter into a supplement
to the Pledge Agreement and comply with the terms and provisions thereof and (2)
purchase the Additional Pledged Securities to be pledged to the Trustee for the
exclusive benefit of the Holders in such amount as will be sufficient upon
receipt of scheduled interest and principal payments of such Additional Pledged
Securities, as computed by the Company and verified for mathematical accuracy by
KPMG LLP, independent public accountants, or another nationally recognized firm
of independent public accountants selected by the Company, to provide for
payment in full of the first six scheduled interest payments due on the
Securities issued in connection therewith. The Additional Pledged Securities
shall be pledged by the Company to the Trustee for exclusive benefit of the
Holders and shall be held by the Trustee in the Pledged Account pending
disposition pursuant to the Pledge Agreement.

     (e)  Each Holder, by its acceptance of a Security, consents and agrees to
the terms of the Pledge Agreement (including, without limitation, the provisions
providing for foreclosure and release of the Pledged Securities) as the same may
be in effect or may be amended from time to time in writing by

                                       62

<PAGE>

the parties thereto (provided that no amendment that would materially adversely
affect the rights of the Holders may be effected without the consent of each
Holder affected thereby), and authorizes and directs the Trustee to enter into
the Pledge Agreement and to perform its obligations and exercise its rights
thereunder in accordance therewith. The Company shall do or cause to be done all
such acts and things as may be necessary or proper, or as may be required by the
provisions of the Pledge Agreement, to assure and confirm to the Trustee the
security interest in the Pledged Securities contemplated hereby, by the Pledge
Agreement or any part thereof, as from time to time constituted, so as to render
the same available for the security and benefit of this Indenture and of the
Securities secured hereby, according to the intent and purpose herein expressed.
The Company shall take, or shall cause to be taken, upon request of the Trustee,
any and all actions reasonably required to cause the Pledge Agreement to create
and maintain, as security for the obligations of the Company under this
Indenture and the Securities as provided in the Pledge Agreement, valid and
enforceable first priority perfected liens in and on all the Pledged Securities,
in favor of the Trustee for its benefit and the ratable benefit of the Holders,
superior to and prior to the rights of third Persons and subject to no other
Liens.

     (f)  The release of any Pledged Securities pursuant to the Pledge Agreement
will not be deemed to impair the security under this Indenture in contravention
of the provisions hereof if and to the extent the Pledged Securities are
released pursuant to this Indenture and the Pledge Agreement. To the extent
applicable, the Company shall cause Section 314(d) of the TIA relating to the
release of property or securities from the Lien and security interest of the
Pledge Agreement and relating to the substitution therefor of any property or
securities to be subjected to the Lien and security interest of the Pledge
Agreement to be complied with. Any certificate or opinion required by Section
314(d) of the TIA may be made by an Officer of the Company, except in cases
where Section 314(d) of the TIA requires that such certificate or opinion be
made by an independent Person, which Person shall be an independent engineer,
appraiser or other expert selected by the Company.

     (g)  The Company shall cause Section 314(b) of the TIA, relating to
Opinions of Counsel regarding the Lien under the Pledge Agreement, to be
complied with. The Trustee may, to the extent permitted by Section 7.01 and 7.02
hereof, accept as conclusive evidence of compliance of the foregoing provisions
the appropriate statements contained in such Opinions of Counsel.

     (h)  The Trustee may, in its sole discretion and without the consent of the
Holders, on behalf of the Holders, take all actions it deems necessary or
appropriate in order to (1) enforce any of the terms of the Pledge Agreement and
(2) collect and receive any and all amounts payable in respect of the
obligations of the Company thereunder. The Trustee shall have the authority
necessary in order to institute and maintain such suits and proceedings as the
Trustee may deem expedient to preserve or protect its interests and the
interests of the Holders in the Pledged Securities (including the authority to
institute and maintain suits or proceedings to restrain the enforcement of, or
compliance with, any legislative or other governmental enactment, rule or order
that may be unconstitutional or otherwise invalid if the enforcement of, or
compliance with, such enactment, rule or order would impair the security
interest hereunder or be prejudicial to the interests of the Holders or the
Trustee).

     (i)  Beyond the exercise of reasonable care in the custody and preservation
thereof, the Trustee shall have no duty as to any Pledged Securities in its
possession or any income thereon or as to preservation of rights against prior
parties or any other rights pertaining thereto, and the Trustee shall not be
responsible for filing any financing or continuation statements or recording any
documents or instruments in any public office at any time or times or otherwise
perfecting or maintaining the perfection of any security interest in the Pledged
Securities. The Trustee shall be deemed to have exercised reasonable care in the
custody and preservation of the Pledged Securities in its possession if the
Pledged Securities are accorded treatment substantially equal to that which it
accords its own property or property held in similar accounts and shall not be
liable or responsible for any loss or diminution in the value of

                                       63

<PAGE>

any of the Pledged Securities, by reason of the act or omission of the Trustee,
any carrier, forwarding agency or other agent or bailee selected by the Trustee
in good faith.

     (j)  The Trustee shall not be responsible for the existence, genuineness or
value of any of the Pledged Securities or for the validity, perfection, priority
or enforceability of the Liens in any of the Pledged Securities, whether
impaired by operation of law or otherwise, for the validity or sufficiency of
the Pledged Securities or any agreement or assignment contained therein, for the
validity of the title of the Company to the Pledged Securities, for insuring the
Pledged Securities or for the payment of taxes, charges, assessments or Liens
upon the Pledged Securities or otherwise as to the maintenance of the Pledged
Securities. The Trustee shall have no duty to ascertain or inquire as to the
performance or observance of any of the terms of this Indenture or the Pledge
Agreement by the Company.

                                  ARTICLE XIII

                                  SUBORDINATION

     Section 13.01 Agreement To Subordinate.

     The Company agrees, and each Holder by accepting a Security agrees, that
the payment of Principal Amount at Maturity of and cash interest on (including
Liquidated Damages, if any) and other obligations of any kind evidenced by the
Securities and this Indenture are subordinated in right of payment, to the
extent and in the manner provided in this Article 13, to the prior payment in
full in cash or cash equivalents (or otherwise to the extent holders accept
satisfaction of amounts due by settlement in other than cash or cash
equivalents) of all senior indebtedness whether outstanding on the date hereof
or hereafter incurred.

     Section 13.02 Liquidation; Dissolution; Bankruptcy.

     In the event of any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relating to the Company or to its assets, or any
liquidation, dissolution or other winding-up of the Company, whether voluntary
or involuntary, or any assignment for the benefit of creditors or other
marshaling of assets or liabilities of the Company (except in connection with
the consolidation or merger of the Company or its liquidation or dissolution
following the conveyance, transfer or lease of its properties and assets
substantially upon the terms and conditions described in Article 7), the holders
of senior indebtedness shall be entitled to receive payment in full in cash or
cash equivalents (or otherwise to the extent holders accept satisfaction of
amounts due by settlement in other than cash or cash equivalents) of all senior
indebtedness, or provision shall be made for such payment, before the Holders
will be entitled to receive any payment or distribution of any kind or character
(other than (1) payments made pursuant to the Pledge Agreement, and (2) payment
or distribution in the form of Permitted Junior Securities, whether on account
of principal of or Liquidated Damages, if any, or cash interest on the
Securities); and any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities (other than (A)
payments made pursuant to the Pledge Agreement or (B) payments or distribution
in the form of Permitted Junior Securities), by set-off or otherwise, to which
the Holders or the Trustee would be entitled but for the provisions of this
Article 13 shall be paid by the liquidating trustee or agent or other person
making such payment or distribution directly to the holders of senior
indebtedness or their representatives ratably according to the aggregate amounts
remaining unpaid on account of the senior indebtedness to the extent necessary
to make payment in full in cash or cash equivalents (or otherwise to the extent

     Section 13.03 Default On Designated Senior Indebtedness.

     (a)  No payment or distribution of any assets of the Company of any kind or
character, whether in cash, property or securities (other than (1) any payments
made pursuant to the Pledge Agreement or (2) payments in the form of Permitted
Junior Securities), may be made by or on behalf of the Company on account of
principal of, accrued Original Issue Discount or cash interest or Liquidated
Damages, if any, on the Securities or on account of the purchase, redemption or
other acquisition of Securities upon the occurrence of any Payment Default and
after receipt by the Trustee of written notice from the representative of the
holders of the Designated Senior Indebtedness in respect of which such Payment
Default exists, until such Payment Default shall have been cured or waived in
writing or shall have ceased to exist or the senior indebtedness giving rise to
such Payment Default shall have been discharged or paid in full in cash or cash
equivalents (or otherwise to the extent Holders accept satisfaction of amounts
due by settlement in other than cash or cash equivalents).

     (b)  No payment or distribution of any assets of the Company of any kind or
character, whether in cash, property or securities (other than (1) payments made
pursuant to the Pledge Agreement or (2) payments in the form of Permitted Junior
Securities), may be made by or on behalf of the Company on account of principal
of, accrued Original Issue Discount or cash interest or Liquidated Damages, if
any, on the Securities or on account of the purchase, redemption or other
acquisition of Securities during a Payment Blockage Period arising as a result
of Non-Payment Default.

     A "Payment Blockage Period" will commence upon the date of receipt by the
Trustee of written notice from the representative of the holders of the
Designated Senior Indebtedness in respect of which the Non-Payment Default
exists and shall end on the earliest of:

          .  179 days thereafter (provided that any Designated Senior
             Indebtedness as to which notice was given shall not theretofore
             have been accelerated);

          .  the date on which such Non-Payment Default is cured, waived or
             ceases to exist;

          .  the date on which such Designated Senior Indebtedness is discharged
             or paid in full; or

          .  the date on which such Payment Blockage Period shall have been
             terminated by written notice to the Trustee or the Company from the
             representative initiating such Payment Blockage Period;

after which the Company will resume making any and all required payments in
respect of the Securities, including any missed payments and additional
interest, if any. No more than one Payment Blockage Period may be commenced
during any period of 365 consecutive days. No Non-Payment Default that existed
or was continuing on the date of the commencement of any Payment Blockage Period
shall be, or can be made, the basis for the commencement of a subsequent Payment
Blockage Period, unless such Non-Payment Default has been cured or waived for a
period of not less than 90 consecutive days subsequent to the commencement of
such initial Payment Blockage Period.

     Section 13.04 Acceleration Of Securities.

     If payment of the Securities is accelerated because of an Event of Default,
the Company shall promptly notify holders of senior indebtedness of the
acceleration.

     Section 13.05 When Distribution Must Be Paid Over.

     (a)  In the event that, notwithstanding the provisions of Sections 13.02
and 13.03, any payment or distribution, whether in cash, property or securities,
shall be received by the Trustee or any Holder, which is prohibited by such
provisions, then and in such event such payment shall be held for the benefit
of, and shall be paid over and delivered by such Trustee or Holder to, the
representative of holders of senior indebtedness, as their interests may appear,
for application to senior indebtedness to the extent necessary to pay or to
provide for the payment of all such senior indebtedness in full in cash or cash
equivalents (or otherwise to the extent holders accept satisfaction of amounts
due by settlement in other than cash or cash equivalents).

     (b)  With respect to the holders of senior indebtedness, the Trustee
undertakes to perform only such obligations on the part of the Trustee as are
specifically set forth in this Article 13, and no implied covenants or
obligations with respect to the holders of senior indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of senior indebtedness, and shall not be
liable to any such holders if the Trustee shall pay over or distribute to or on
behalf of Holders or the Company or any other Person money or assets to which
any holders of senior indebtedness shall be entitled by virtue of this Article
13, except if such payment is made as a result of the willful misconduct or
gross negligence of the Trustee.

     Section 13.06 Notice By The Company.

     The Company shall promptly notify the Trustee and the Paying Agent of any
facts known to the Company that would cause a payment of any obligations with
respect to the Securities to violate this Article 13, but failure to give such
notice shall not affect the subordination of the Securities to the senior
indebtedness as provided in this Article 13.

     Section 13.07 Subrogation.

     After all senior indebtedness is paid in full and until the Securities are
paid in full, Holders shall be subrogated (equally and ratably with all other
indebtedness that is equal in right of payment to the Securities) to the rights
of holders of senior indebtedness to receive distributions applicable to senior
indebtedness to the extent that distributions otherwise payable to the Holders
have been applied to the payment of senior indebtedness. A distribution made
under this Article 13 to holders of senior indebtedness that otherwise would
have been made to Holders is not, as between the Company and Holders, a payment
by the Company of the Securities.

     Section 13.08 Relative Rights.

     This Article 13 defines the relative rights of Holders and holders of
senior indebtedness. Nothing in this Indenture shall: (a) impair, as between the
Company and Holders, the obligation of the Company, which is absolute and
unconditional, to pay principal of and interest on the Securities in accordance
with their terms; (b) affect the relative rights of Holders and creditors of the
Company other than their rights in relation to holders of senior indebtedness;
or (c) prevent the Trustee or any Holder from exercising its available remedies
upon a Default or Event of Default, subject to the rights of holders and owners
of senior indebtedness to receive distributions and payments otherwise payable
to Holders. If the Company fails because of this Article 13 to pay principal of
or interest on a Security on the Final Maturity Date or an Interest Payment
Date, the failure is still a Default or Event of Default.

     Section 13.09 Subordination May Not Be Impaired By The Company.

     (a)  No right of any holder of senior indebtedness to enforce the
subordination of the indebtedness evidenced by the Securities shall be impaired
by any act or failure to act by the Company or any Holder or by the failure of
the Company or any Holder to comply with this Indenture.

     (b)  Without in any way limiting the generality of this Section 13.09, the
holders of senior indebtedness 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 Trustee or the Holders and without impairing or releasing
the subordination provided in this Article 13 or the obligations hereunder of
the Holders to the holders of senior indebtedness, do any one or more of the
following: (1) change the manner, place or terms of payment or extend the time
of payment of, or renew or alter, senior indebtedness, or any instrument
evidencing the same or any agreement under which senior indebtedness is
outstanding or secured; (2) sell, exchange, release, foreclose against or
otherwise deal with any property pledged, mortgaged or otherwise securing senior
indebtedness; (3) release any Person liable in any manner for the collection of
senior indebtedness; and (4) exercise or refrain from exercising any rights
against the Company, and Subsidiary thereof or any other Person.

     Section 13.10 Distribution Or Notice To Representative.

     (a)  Whenever a distribution is to be made or a notice given to holders of
any senior indebtedness, the distribution may be made and the notice given to
their trustee or representative.

     (b)  Upon any payment or distribution of assets of the Company referred to
in this Article 13, the Trustee and the Holders shall be entitled to rely upon
any order or decree made by any court of competent jurisdiction or upon any
certificate of such representative(s) or of the liquidating trustee or agent or
other Person making any distribution to the Trustee or to the Holders for the
purpose of ascertaining the Persons entitled to participate in such
distribution, all holders of the senior indebtedness 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
13.

     Section 13.11 Rights Of Trustee And Paying Agent.

     (a)  Notwithstanding the provisions of this Article 13 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Securities, unless a Responsible Officer of the Trustee
shall have received at its Corporate Trust Office at least three Business Days
prior to the date of such payment written notice of facts that would cause the
payment of any obligations with respect to the Securities to violate this
Article 13. Only the Company or the representative of the Company or of holders
of senior indebtedness may give the notice. Nothing in this Article 13 shall
impair the claims of, or payments to, the Trustee under or pursuant to Section
9.06.

     (b)  The Trustee in its individual or any other capacity may hold senior
indebtedness with the same rights it would have if it were not Trustee.

                       [FORM OF REVERSE SIDE OF SECURITY]


                                MGI PHARMA, INC.
                 SENIOR SUBORDINATED CONVERTIBLE NOTES DUE 2024

1.   INTEREST

     MGI PHARMA, INC., a Minnesota corporation (the "Company", which term shall
include any successor corporation under the Indenture hereinafter referred to),
promises to pay cash interest on the Principal Amount at Maturity of this
Security at the rate of 1.6821% per annum. The Company shall pay cash interest
semiannually on March 2 and September 2 of each year (each an "Interest Payment
Date"), commencing September 2, 2004 until March 2, 2011. After March 2, 2011,
this Security shall not bear cash interest, provided, however, that if there is
not an existing default in the payment of cash interest and if this Security is
authenticated between a Regular Record Date and the next succeeding Interest
Payment Date, interest shall accrue from such Interest Payment Date. Each
payment of cash interest will include cash interest accrued through the day
before the relevant Interest Payment Date (or purchase or redemption date, as
the case may be). Cash interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months. Any reference herein to interest accrued or
payable as of any date shall include any Liquidated Damages accrued or payable
on such date as provided in the Registration Rights Agreement.

     During the period from and after March 2, 2011 in which a Security remains
outstanding, Original Issue Discount (the difference between the Issue Price and
the Principal Amount at Maturity of the Security) shall accrue daily at the rate
of 2.25% per annum, with the accrual to be calculated on a semiannual bond
equivalent basis using a 360-day year composed of twelve 30-day months.

     No sinking fund is provided for the Securities.

2.   METHOD OF PAYMENT

     The Company shall pay interest on this Security (except defaulted interest)
to the person who is the Holder of this Security at the close of business on
February 15 or August 15, as the case may be, (each, a "Regular Record Date")
next preceding the related Interest Payment Date. The Holder must surrender this
Security to a Paying Agent to collect payment of principal. The Company will pay
principal and interest in money of the United States that at the time of payment
is legal tender for payment of public and private debts. The Company may pay
principal and interest in respect of any Certificated Security by check or wire
payable in such money; provided, however, that a Holder with an aggregate
Principal Amount at Maturity in excess of $2,000,000 will be paid by wire
transfer in immediately available funds at the election of such Holder if such
Holder has provided wire transfer instructions to the Trustee at least 10
Business Days prior to the Payment Date. The Company may mail an interest check
to the Holder's registered address. Notwithstanding the foregoing, so long as
this Security is registered in the name of a Depositary or its nominee, all
payments hereon shall be made by wire transfer of immediately available funds to
the account of the Depositary or its nominee.

     Any wire transfer instructions received by the Trustee will remain in
effect until revoked by the Holder.

Liquidated Damages, if any, to, but excluding, the Redemption Date, such
Securities or portions of them called for redemption will cease to be

11.  PERSONS DEEMED OWNERS

     The Holder of a Security may be treated as the owner of it for all
purposes.

12.  UNCLAIMED MONEY

     If money for the payment of principal or interest remains unclaimed for two
years, the Trustee and any Paying Agent will pay the money back to the Company
at its written request, subject to applicable unclaimed property law and the
provisions of the Indenture. After that, Holders entitled to money must look to
the Company for payment as general creditors unless an applicable abandoned
property law designates another person.

13.  AMENDMENT, SUPPLEMENT AND WAIVER

     Subject to certain exceptions, the Indenture or the Securities may be
amended or supplemented with the consent of the Holders of at least a majority
in aggregate Principal Amount at Maturity of the Securities then outstanding,
and an existing default or Event of Default and its consequence or compliance
with any provision of the Indenture or the Securities may be waived in a
particular instance with the consent of the Holders of a majority in aggregate
Principal Amount at Maturity of the Securities then outstanding. Without the
consent of or notice to any Holder, the Company and the Trustee may amend or
supplement the Indenture or the Securities to, among other things, cure any
ambiguity, defect or inconsistency or make any other change that does not
adversely affect the rights of the Holders in any material respect.

14.  SUBORDINATION

in other than cash or cash equivalents) of all senior indebtedness whether
outstanding on the date of the Indenture or thereafter incurred.

15.  SUCCESSOR ENTITY

under the Securities and the Indenture in accordance with the terms and
conditions of the Indenture, the predecessor corporation (except in certain

     In connection with such request and in respect of each such Security, the
Transferor does hereby certify that the Transferor is familiar with transfer
restrictions relating to the Securities as provided in Section 2.12 of the
Indenture dated as of March 2, 2004 between MGI PHARMA, INC. and Wells Fargo
Bank, National Association, as trustee (the "Indenture"), and the transfer of
such Security is being made pursuant to an effective registration statement
under the Securities Act of 1933, as amended (the "Securities Act") (check
applicable box) or the transfer or exchange, as the case may be, of such
Security does not require registration under the Securities Act because (check
applicable box):

     [ ]  Such Security is being transferred pursuant to an effective
          registration statement under the Securities Act.

     [ ]  Such Security is being acquired for the Transferor's own account,
          without transfer.

     [ ]  Such Security is being transferred to the Company or a Subsidiary (as
          defined in the Indenture) of the Company.

     [ ]  Such Security is being transferred to a person the Transferor
          reasonably believes is a "qualified institutional buyer" (as defined
          in Rule 144A or any successor provision thereto ("Rule 144A") under
          the Securities Act) that is purchasing for its own account or for the
          account of a "qualified institutional buyer", in each case to whom
          notice has been given that the transfer is being made in reliance on
          such Rule 144A, and in each case in reliance on Rule 144A.

     [ ]  Such Security is being transferred pursuant to and in compliance with
          an exemption from the registration requirements under the Securities
          Act in accordance with Rule 144 (or any successor thereto) ("Rule
          144") under the Securities Act.

     [ ]  Such Security is being transferred to a non-U.S. Person in an offshore
          transaction in compliance with Rule 904 of Regulation S under the
          Securities Act (or any successor thereto).

     [ ]  Such Security is being transferred pursuant to and in compliance with
          an exemption from the registration requirements of the Securities Act
          (other than an exemption referred to above) and as a result of which
          such Security will, upon such transfer, cease to be a "restricted
          security" within the meaning of Rule 144 under the Securities Act.
