                                    ARTICLE 2
                General Terms And Conditions Of The Senior Notes

      Section 2.01. Designation and Principal Amount. There is hereby authorized
and established a series of Securities designated as 1.50% Convertible Senior
Notes due 2024 in aggregate principal amount of $300,000,000 (up to $330,000,000
in the event the Underwriters exercise the over-allotment option in full to
purchase additional Senior Notes granted to them in the Underwriting Agreement).
The Senior Notes may be issued from time to time upon written


                                       6

order of the Company for the authentication and delivery of Senior Notes
pursuant to Section 3.03 of the Base Indenture.

      Section 2.02. Payment of Principal and Interest. (a) The principal of each
Senior Note shall be due at the Stated Maturity of such Senior Note (unless
earlier converted, redeemed or purchased by the Company). The unpaid principal
amount of the Senior Notes shall bear Interest at the rate of 1.50% per annum,
until paid or duly provided for, and such Interest shall accrue from February
17, 2004 or from the most recent Interest Payment Date to which Interest has
been paid or duly provided for. Except as provided herein, Interest shall be
paid semi-annually in arrears on each Interest Payment Date to the Person or
Persons in whose name the Senior Notes are registered on the Record Date for
such Interest Payment Date.

      (b) Payments of Interest on the Senior Notes shall include Interest
accrued to but excluding the respective Interest Payment Dates, Redemption Date,
Purchase Date or Fundamental Change Purchase Date, as the case may be; provided,
however, that in the case of a Redemption Date that occurs after a Record Date
and prior to the corresponding Interest Payment Date, the Company shall pay the
full amount of accrued and unpaid Interest to such Interest Payment Date to the
Holder on the corresponding Redemption Date. Payments of Interest for the Senior
Notes shall be computed and paid on the basis of a 360-day year comprised of
twelve 30-day months. If any Interest Payment Date (other than an Interest
Payment Date coinciding with the Stated Maturity or earlier Redemption Date,
Purchase Date or Fundamental Change Purchase Date) of a Senior Note falls on a
day that is not a Business Day, such Interest Payment Date will be postponed to
the next succeeding Business Day, provided that, if such Business Day falls in
the next succeeding calendar month, the Interest Payment Date will be brought
forward to the immediately preceding Business Day. If the Stated Maturity,
Redemption Date, Purchase Date or Fundamental Change Purchase Date of a Senior
Note would fall on a day that is not a Business Day, the required payment of
Interest, if any, and principal will be made on the next succeeding Business Day
and no Interest on such payment will accrue for the period from and after the
Stated Maturity, Redemption Date or Purchase Date or Fundamental Change Purchase
Date to such next succeeding Business Day.

      Section 2.03. Denominations. The Senior Notes shall initially be issued in
fully registered form, without coupons, in denominations of $1,000 and any
integral multiple thereof.

      Section 2.04. Global Senior Notes. (a) The Senior Notes shall initially be
issued in the form of one or more Global Senior Notes. The Company initially
appoints The Depository Trust Company ("DTC") to act as the Depositary. The
Senior Notes shall be registered in the name of Cede & Co., as nominee of DTC,
and deposited with the Trustee as Custodian for DTC. The Company shall issue


                                       7

the Senior Notes in the form of Certificated Senior Notes if DTC notifies the
Company that it is unwilling or unable to continue as Depositary or DTC ceases
to be a clearing agency registered under the Exchange Act and a successor
Depositary is not appointed by the Company within 90 days. In addition
beneficial interests in a Global Senior Note may be exchanged for Certificated
Senior Note upon request by or on behalf of DTC in accordance with DTC's
customary procedures. The Company may determine at any time and in its sole
discretion that Senior Notes shall no longer be represented by Senior Global
Notes, in which case the Company will issue Certificated Senior Notes in
exchange for the Senior Global Notes.

      (b) Record ownership of the Global Senior Notes may be transferred, in
whole or in part, only to another nominee of DTC or to a successor of DTC or its
nominee, except as set forth in this Section 2.04. An owner of a beneficial
interest in the Global Senior Notes may hold its interests in the Global Senior
Notes directly through DTC if such owner is a participant in DTC, or indirectly
through organizations which are direct DTC participants if such owner is not a
participant in DTC. Transfers between direct DTC participants will be effected
in the ordinary way in accordance with DTC's rules and will be settled in
same-day funds. Beneficial interests in the Global Senior Notes held by DTC may
also be owned through certain banks, brokers, dealers, trust companies and other
parties that clear through or maintain a custodial relationship with a direct
DTC participant, either directly or indirectly. Payment of Defaulted Interest
shall be made as provided in the Base Indenture.

      Section 2.05. No Defeasance. The provisions of Article Thirteen of the
Base Indenture shall not apply to the Senior Notes.

      Section 2.06. No Sinking Fund. The provisions of Article Twelve of the
Base Indenture shall not apply to the Senior Notes and the Senior Notes are not
entitled to the benefit of any sinking fund.

      Section 2.07. Register of Senior Notes; Paying Agent; Conversion Agent.
The Security Registrar, Paying Agent, Conversion Agent, the Calculation Agent
and the Custodian for the Senior Notes shall initially be the Trustee.

      Section 2.08. Place of Payment. The place of payment for the Senior Notes
shall be at the Company's office or agency in the Borough of Manhattan, The City
of New York, which initially shall be the Corporate Trust Office. So long as the
Senior Notes are in the form of registered Global Senior Notes, the Company
agrees that payments of Interest on, and any portion of the principal of, the
Senior Notes shall be made by the Paying Agent, upon receipt from the Company of
immediately available funds, directly to the Depositary (by Federal funds wire
transfer).


                                       8

      Section 2.09. Satisfaction and Discharge. The provisions of Article Four
of the Base Indenture shall be applicable to the Indenture and the Senior Notes;
provided, however, that the provisions in Section 4.01(1)(b)(ii) and Section
4.01(1)(b)(iii) of the Base Indenture shall not apply to the Indenture and the
Senior Notes.

                                    ARTICLE 3
                            Redemption And Purchases

      Section 3.01. Company's Right to Redeem; Notices to Trustee. Prior to
February 16, 2009, the Senior Notes will not be redeemable at the Company's
option. Beginning on February 16, 2009, the Company, at its option, may redeem
the Senior Notes in accordance with the provisions of Section 5 of the Senior
Notes in U.S. legal tender ("CASH") at any time as a whole, or from time to time
in part, at a redemption price (the "REDEMPTION PRICE") equal to 100% of the
principal amount of the Senior Notes redeemed plus accrued and unpaid Interest,
if any, on the Senior Notes redeemed to (but excluding) the Redemption Date. If
the Company elects to redeem Senior Notes pursuant to Section 5 of the Senior
Notes, it shall notify the Trustee in writing of the Redemption Date, the
principal amount of Senior Notes to be redeemed and the Redemption Price.

      The Company shall give the notice to the Trustee provided for in this
Section 3.01 by a Company Order, at least 45 days but not more than 60 days
before the Redemption Date (unless a shorter notice shall be satisfactory to the
Trustee).

      Senior Notes called for redemption may be surrendered for conversion from
the date of notice of the redemption until the close of business on the Business
Day immediately preceding the Redemption Date.

      Section 3.02. Selection of Senior Notes to be Redeemed. If less than all
of the Senior Notes are to be redeemed, unless the procedures of the Depositary
provide otherwise, the Trustee shall select the Senior Notes to be redeemed by
lot or on a pro rata basis. The Trustee shall make the selection within five
Business Days after it receives the notice provided for in Section 3.01 from
outstanding Senior Notes not previously called for redemption. The Trustee may
select for redemption portions of the principal amount of Senior Notes that have
denominations larger than $1,000.

      Senior Notes and portions of Senior Notes that the Trustee selects shall
be in principal amounts of $1,000 or an integral multiple of $1,000. Provisions
of this Indenture that apply to Senior Notes called for redemption also apply to
portions of Senior Notes called for redemption. The Trustee shall notify the


                                       9

Company promptly of the Senior Notes or portions of the Senior Notes to be
redeemed.

      Senior Notes and portions of Senior Notes that are to be redeemed are
convertible, pursuant to Section 5.01(c), by the Holder until the close of
business on the Business Day prior to the Redemption Date. If any Security
selected for partial redemption is converted in part before termination of the
conversion right with respect to the portion of the Senior Notes selected, the
converted portion of such Senior Notes shall be deemed (so far as may be) to be
the portion selected for redemption. Senior Notes that have been converted
during a selection of Senior Notes to be redeemed may be treated by the Trustee
as outstanding for the purpose of such selection.

      Section 3.03. Notice of Redemption. At least 30 days but not more than 60
days before a Redemption Date, the Company shall mail a notice of redemption by
first-class mail, postage prepaid, to each Holder of Senior Notes to be
redeemed.

      The notice shall identify the Senior Notes to be redeemed and shall state:

      (1) the Redemption Date;

      (2) the Redemption Price;

      (3) the Conversion Rate;

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

      (5) that Senior Notes called for redemption may be converted at any time
before the close of business on the Business Day prior to the Redemption Date;

      (6) that Holders who want to convert their Senior Notes must satisfy the
requirements set forth in Section 8 of the Senior Notes;

      (7) that Senior Notes called for redemption must be surrendered to the
Paying Agent to collect the Redemption Price;

      (8) if fewer than all of the outstanding Senior Notes are to be redeemed,
the certificate numbers, if any, and principal amounts of the particular Senior
Notes to be redeemed;

      (9) that, unless the Company defaults in making payment of such Redemption
Price and Interest, if any, on Senior Notes called for redemption will cease to
accrue on and after the Redemption Date; and


                                       10

      (10) the CUSIP number(s) of the Senior Notes.

      At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at the Company's expense, provided that the Company
makes such request at least seven Business Days (or such shorter period as may
be satisfactory to the Trustee) prior to the date by which such notice of
redemption must be given to Holders in accordance with this Section 3.03.

      Section 3.04. Effect of Notice of Redemption. Once notice of redemption is
given, Senior Notes called for redemption become due and payable on the
Redemption Date and at the Redemption Price stated in the notice except for
Senior Notes which are converted in accordance with the terms of the Indenture.
Upon surrender to the Paying Agent, such Senior Notes shall be paid at the
Redemption Price stated in the notice.

      Section 3.05. Deposit of Redemption Price and Senior Notes Redeemed in
Part. Prior to 10:00 a.m. (New York City time), on the Redemption Date, the
Company shall deposit with the Paying Agent (or if the Company or a Subsidiary
or an Affiliate of either of them is the Paying Agent, shall segregate and hold
in trust) money sufficient to pay the Redemption Price of all Senior Notes to be
redeemed on that date other than Senior Notes or portions of Senior Notes called
for redemption which on or prior thereto 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 conversion of Senior Notes pursuant to Article 5 hereof. If
such money is then held by the Company in trust and is not required for such
purpose it shall be discharged from such trust.

      If money sufficient to pay the Redemption Price of all Senior Notes (or
portions thereof) to be redeemed on the Redemption Date is deposited with the
Paying Agent prior to 10:00 a.m. (New York City time) on the Redemption Date,
immediately on and after such Redemption Date, Interest, if any, will cease to
accrue on such Senior Notes or portions thereof. Once notice of redemption is
given, Senior Notes called for redemption become due and payable on the
Redemption Date and at the Redemption Price stated in the notice except for
Senior Notes which are converted in accordance with the terms of the Indenture.
Upon surrender to the Paying Agent, such Senior Notes shall be paid at the
Redemption Price stated in the notice.

      Section 3.06. Purchase of Senior Notes by the Company at Option of the
Holder. Senior Notes shall be purchased by the Company pursuant to Section 6 of
the Senior Notes at the option of the Holder on February 15, 2009, February 15,
2014 and February 15, 2019 (each, a "PURCHASE DATE"), at a purchase price equal
to 100% of the principal amount of those Senior Notes, plus accrued and unpaid
Interest, if any, on those Senior Notes, to (but excluding) such Purchase


                                       11

Date (the "PURCHASE PRICE"). Senior Notes repurchased by the Company on February
15, 2009 (the "FIRST PURCHASE DATE") shall be paid in cash and subsequent
repurchases on February 15, 2014 and February 15, 2019 (each a "SUBSEQUENT
PURCHASE DATE") shall be paid in cash, shares of Common Stock or in any
combination of cash and shares of Common Stock at the Company's option in the
manner pursuant to Section 3.08. Notwithstanding anything to the contrary in the
Indenture, at any time prior to Stated Maturity, the Company may irrevocably
elect, in its sole discretion without the consent of the Holders of the Senior
Notes, by notice to the Trustee and the Holders of the Senior Notes to satisfy
100% of the principal amount of the Senior Notes so required to be repurchased
by the Company pursuant to this Section 3.06 after the date of such election
plus accrued and unpaid Interest, if any, on the Senior Notes in cash. At least
22 Business Days prior to each Purchase Date, the Company or the Trustee (at the
Company's request and expense) shall notify the Holders of the Senior Notes of
their purchase right, the relevant Purchase Date and the purchase procedures.
Purchases of Senior Notes hereunder shall be made, at the option of the Holder
thereof, upon:

            (i) delivery to the Paying Agent by the Holder of a written notice
      of purchase (a "PURCHASE NOTICE") during the period beginning at any time
      from the opening of business on the date that is 22 Business Days prior to
      the relevant Purchase Date until the close of business on the Business Day
      prior to such Purchase Date stating:

                  (A) the certificate number of the Senior Note which the Holder
            will deliver to be purchased or the appropriate Depositary
            procedures if Certificated Senior Notes have not been issued for
            such Senior Note,

                  (B) the portion of the principal amount of the Senior Note
            which the Holder will deliver to be purchased, which portion must be
            in principal amounts of $1,000 or an integral multiple of $1,000,

                  (C) that such Senior Note shall be purchased by the Company as
            of the Purchase Date pursuant to the terms and conditions specified
            in Section 6 of the Senior Notes and in the Indenture, and

                  (D) in the event the Company elects, pursuant to Section
            3.08(c), to pay the Purchase Price, in whole or in part, in shares
            of Common Stock but such portion of the Purchase Price shall
            ultimately be paid to such Holder entirely in cash because any of
            the conditions to payment of the Purchase Price in shares of Common
            Stock are not satisfied prior to the close of business


                                       12

            on the third Business Day prior to the relevant Purchase Date, as
            set forth in Section 3.08, whether such Holder elects (i) to
            withdraw such Purchase Notice as to some or all of the Senior Notes
            to which such Purchase Notice relates (stating the principal amount
            and certificate numbers, if any, of the Senior Notes as to which
            such withdrawal shall relate), or (ii) to receive cash in respect of
            the entire Purchase Price for all Senior Notes (or portions thereof)
            to which such Purchase Notice relates; and

            (ii) delivery of such Senior Note to the Paying Agent at any time
      after delivery of the Purchase Notice (together with all necessary
      endorsements) at the offices of the Paying Agent, such delivery being a
      condition to receipt by the Holder of the Purchase Price therefor;
      provided, however, that such Purchase Price shall be so paid pursuant to
      this Section 3.06 only if the Senior Note so delivered to the Paying Agent
      shall conform in all respects to the description thereof in the related
      Purchase Notice.

      If a Holder, in such Holder's Purchase Notice and in any written notice of
withdrawal delivered by such Holder pursuant to the terms of Section 3.08, fails
to indicate such Holder's choice with respect to the election set forth in
clause (D) of Section 3.06(i), such Holder shall be deemed to have elected to
receive cash in respect of the entire Purchase Price for all Senior Notes
subject to such Purchase Notice in the circumstances set forth in such clause
(D).

      The Company shall purchase from the Holder thereof, pursuant to this
Section 3.06, such portion of a Senior Note, if the principal amount of such
portion is $1,000 or an integral multiple of $1,000. Provisions of the Indenture
that apply to the purchase of all of a Senior Note also apply to the purchase of
such portion of such Senior Note.

      Any purchase by the Company contemplated pursuant to the provisions of
this Section 3.06 shall be consummated by the delivery of the consideration to
be received by the Holder promptly following the later of the Purchase Date and
the date the Senior Notes are delivered to, and received by, the Paying Agent.

      Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent the Purchase Notice contemplated by this Section 3.06 shall
have the right to withdraw such Purchase Notice at any time prior to the close
of business on the Business Day immediately prior to the Purchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 3.11.

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


                                       13

      Section 3.07. Purchase of Senior Notes at Option of the Holder Upon
Fundamental Change. (a) (i) If a Fundamental Change occurs (subject to certain
exceptions set forth below), the Senior Notes not previously purchased by the
Company shall be purchased by the Company, in cash, at the option of the Holder
thereof, at a purchase price equal to 100% of the principal amount of those
Senior Notes, plus accrued and unpaid Interest, if any, on those Senior Notes to
(but excluding) the Fundamental Change Purchase Date (the "FUNDAMENTAL CHANGE
PURCHASE PRICE"), as of the date that is no later than 25 Business Days after
the date of the notice of Fundamental Change mailed by the Company pursuant to
Section 3.07(b) (the "FUNDAMENTAL CHANGE PURCHASE DATE"), subject to
satisfaction by or on behalf of the Holder of the requirements set forth in
Section 3.07(c); provided that, if the Fundamental Change Purchase Date is after
a Record Date and before the next succeeding Interest Payment Date, accrued and
unpaid Interest, if any, on those Senior Notes shall be paid to the Holder as of
that Record Date.

      A "FUNDAMENTAL CHANGE" will be deemed to have occurred at such time after
the Senior Notes are originally issued when any of the following events shall
occur:

                  (A) the acquisition by any person, including any syndicate or
            group deemed to be a "PERSON" under Section 13(d)(3) of the Exchange
            Act of beneficial ownership, directly or indirectly through a
            purchase, merger or other acquisition transaction or series of
            purchase, merger or other acquisition transactions, of shares of the
            Capital Stock of the Company entitling that person to exercise 50%
            or more of the total voting power of all shares of the Capital Stock
            of the Company entitled to vote generally in elections of directors,
            other than any acquisition by the Company, any of its Subsidiaries,
            or any of the employee benefit plans of the Company (except that any
            of those persons shall be deemed to have beneficial ownership of all
            securities it has the right to acquire, whether the right is

                  outstanding shares of the Company's Capital Stock; or (2)
                  pursuant to which holders of the Company's Capital Stock

                  issuance; or

                        (b) any merger, share exchange, transfer of assets or
                  similar transaction solely for the purpose of changing the
                  Company's jurisdiction of incorporation and resulting in a
                  reclassification, conversion or exchange of outstanding shares
                  of Common Stock, if at all, solely into shares of common
                  stock, ordinary shares or American Depositary Shares of the
                  surviving Person or a direct or indirect parent of the

            national security exchange or approved for listing on the Nasdaq
            National Market.

      A "CONTINUING DIRECTOR" shall mean, as of any date of determination, any
member of the Board of Directors of the Company who:

                  (A) was a member of the Board of Directors of the Company on

            (ii) Notwithstanding the provisions of Section 3.07(a)(i), the
      Company shall not be required to purchase the Senior Notes of the Holders
      upon a Fundamental Change pursuant to this Section 3.07 if:

            traded immediately following a Fundamental Change on a national
            securities exchange or the Nasdaq National Market, and, as a result
            of the transaction or transactions, the Senior Notes become
            convertible into that common stock, ordinary shares or American
            Depositary Shares (and any rights attached thereto).

      For the purposes of this Section 3.07, (x) whether a person is a
"BENEFICIAL OWNER" shall be determined in accordance with Rule 13d-3 under the
Exchange Act and (y) the term "PERSON" includes any syndicate or group that
would be deemed to be a "PERSON" under Section 13(d)(3) of the Exchange Act.

      (b) No later than 15 days after the occurrence of a Fundamental Change,
the Company shall mail a written notice of the Fundamental Change by first class
mail to the Trustee, the Paying Agent and to each Holder (and to beneficial
owners as required by applicable law). The notice shall include a form of

            (vii) the Conversion Rate;

            (viii) that the Senior Notes as to which a Fundamental Change
      Purchase Notice has been given may be converted if they are otherwise
      convertible pursuant to Article 5 hereof only if the Fundamental Change
      Purchase Notice has been withdrawn in accordance with the terms of the
      Indenture;

            (ix) that the Senior Notes must be surrendered to the Paying Agent
      to collect payment;

      Fundamental Change Purchase Date; and

            (xv) the CUSIP number(s) of the Senior Notes.

      (c) A Holder may exercise its rights specified in Section 3.07(a) upon
delivery of a written notice of purchase (a "FUNDAMENTAL CHANGE PURCHASE
NOTICE") to the Paying Agent at any time on or prior to the close of business on
the Fundamental Change Purchase Date stating:

            (i) the certificate number of the Senior Note which the Holder will
      deliver to be purchased or the appropriate Depositary procedures if
      Certificated Senior Notes have not been issued;

            (ii) the portion of the principal amount of the Senior Note which
      the Holder will deliver to be purchased, which portion must be $1,000 or
      an integral multiple of $1,000; and


                                       17

            (iii) that such Senior Note shall be purchased pursuant to the terms
      and conditions specified in Section 6 of the Senior Notes and in the
      Indenture.

      The delivery of such Senior Notes, duly endorsed for transfer, to the
Paying Agent with the Fundamental Change Purchase Notice (together with all
necessary endorsements) at the offices of the Paying Agent shall be a condition
to the receipt by the Holder of the Fundamental Change Purchase Price therefor;
provided, however, that such Fundamental Change Purchase Price shall be so paid
pursuant to this Section 3.07 and Section 3.08 only if the Senior Notes so
delivered to the Paying Agent shall conform in all respects to the description
thereof set forth in the related Fundamental Change Purchase Notice.

      The Company shall purchase from the Holder thereof, pursuant to this
Section 3.07, a portion of a Senior Note if the principal amount of such portion
is $1,000 or an integral multiple of $1,000. Provisions of the Indenture that
apply to the purchase of all of a Senior Note also apply to the purchase of such
portion of such Senior Note.

      Any purchase by the Company contemplated pursuant to the provisions of
this Section 3.07 shall be consummated by the delivery of the consideration to
be received by the Holder on the Fundamental Change Purchase Date.

      Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent the Fundamental Change Purchase Notice contemplated by this
Section 3.07(c) shall have the right to withdraw such Fundamental Change
Purchase Notice at any time prior to the close of business on the Fundamental
Change Purchase Date by delivery of a written notice of withdrawal to the Paying
Agent in accordance with Section 3.11.

      The Paying Agent shall promptly notify the Company of the receipt by it of
any Fundamental Change Purchase Notice or written withdrawal thereof.

      Section 3.08. Company's Right to Elect Manner of Payment of Purchase
Price. (a) The Senior Notes to be purchased on any Subsequent Purchase Date,
pursuant to Section 3.06, may be paid for, in whole or in part, at the election
of the Company, in cash or shares of Common Stock, or in any combination of cash
and shares of Common Stock, subject to the conditions set forth in Section
3.08(c) and Section 3.08(d). Notwithstanding anything to the contrary in the
Indenture, at any time prior to Stated Maturity, the Company may irrevocably
elect, in its sole discretion without the consent of the Holders of the Senior
Notes, by notice to the Trustee and the Holders of the Senior Notes to satisfy
100% of the principal amount of the Senior Notes required to be purchased by the
Company pursuant to Section 3.06 after the date of such election plus accrued
and unpaid Interest, if any, on the Senior Notes in cash. The Company shall
designate, in the Company


                                       18

Notice delivered pursuant to Section 3.08(d), whether the Company will purchase
the Senior Notes for cash or shares of Common Stock, or, if a combination
thereof, the percentages of the Purchase Price, as the case may be, of Senior
Notes in respect of which it will pay in cash or shares of Common Stock;
provided that the Company will pay cash for fractional interests in shares of
Common Stock. For purposes of determining the existence of potential fractional
interests, all Senior Notes subject to purchase by the Company held by a Holder
shall be considered together (no matter how many separate certificates are to be
presented). Each Holder whose Senior Notes are purchased pursuant to Section
3.06 shall receive the same percentage of cash or shares of Common Stock in
payment of the Purchase Price for such Senior Notes, except (i) as provided in
this Section 3.08(c) with regard to the payment of cash in lieu of fractional
shares of Common Stock and (ii) in the event that the Company is unable to
purchase the Senior Notes of a Holder or Holders for shares of Common Stock
because any necessary qualifications or registrations of the shares of Common
Stock under applicable state laws cannot be obtained, or because the conditions
to purchasing the Senior Notes for shares of Common Stock set forth in Section
3.09(c) have not been satisfied, the Company may purchase the Senior Notes of
such Holder or Holders for cash. The Company may not change its election with
respect to the consideration (or components or percentages of components
thereof) to be paid once the Company has given its Company Notice to Holders
except pursuant to Section 3.08(b) or pursuant to Section 3.08(c) in the event
of a failure to satisfy, prior to the close of business on the third Business
Day immediately preceding the Subsequent Purchase Date, any condition to the
payment of the Purchase Price, in whole or in part, in shares of Common Stock.

      At least three Business Days before each Company Notice Date, the Company
shall deliver an Officers' Certificate to the Trustee specifying:

            (i) the manner of payment selected by the Company;

            (ii) the information required by Section 3.08(d) in the Company
      Notice;

            (iii) if the Company elects to pay the Purchase Price or a specified
      percentage thereof, in shares of Common Stock, that the conditions to such
      manner of payment set forth in Section 3.08(c) have been or will be
      complied with; and

            (iv) whether the Company desires the Trustee to give the Company
      Notice required by Section 3.08(d).

      (b) Purchase with Cash. At the option of the Company, the Purchase Price
of Senior Notes in respect of which a Purchase Notice pursuant to Section
3.06(i) has been given, or a specified percentage thereof, may be paid by the

                                       19

Company with cash equal to the aggregate Purchase Price of such Senior Notes;
provided, however, that the Purchase Price of Senior Notes to be purchased on
the First Purchase Date shall be paid in cash. The Company Notice, as provided
in Section 3.08(d), shall be sent to Holders (and to beneficial owners as
required by applicable law) not less than 22 Business Days prior to such
Purchase Date (the "COMPANY NOTICE DATE").

      (c) Payment by Issuance of Shares of Common Stock. At the option of the
Company, the Purchase Price of Senior Notes to be purchased by the Company on a
Subsequent Purchase Date in respect of which a Purchase Notice pursuant to
Section 3.06(i) has been given, or a specified percentage thereof, may be paid
by the Company by the issuance of a number of shares of Common Stock equal to
the quotient obtained by dividing (i) the portion of the Purchase Price to be
paid in shares of Common Stock by (ii) 100% of the Market Price determined by
the Company in the Company Notice, subject to the next succeeding paragraph.

      The Company will not issue a fractional share of Common Stock in payment
of the Purchase Price. Instead, the Company will pay cash based on the current
market value of the fractional share. The current market value of a fractional
share of Common Stock shall be determined, to the nearest 1/1,000th of a share,
by multiplying the Market Price of a full share of Common Stock by the
fractional amount and rounding the product to the nearest whole cent. It is
understood that if a Holder elects to have more than one Senior Note purchased,
the number of shares of Common Stock shall be based on the aggregate amount of
Senior Notes to be purchased.

      If the Company elects to purchase the Senior Notes by the issuance of
shares of Common Stock or in any combination of cash and Common Stock, the
Company Notice, as provided in Section 3.08(d), shall be sent to the Holders
(and to beneficial owners as required by applicable law) not later than the
Company Notice Date.

      The Company's right to exercise its election to purchase Senior Notes
through the issuance of shares of Common Stock shall be conditioned upon:

            (i) the Company's not having given its Company Notice of an election
      to pay entirely in cash and its giving of timely Company Notice of an
      election to purchase all or a specified percentage of the Senior Notes
      with shares of Common Stock as provided herein;

            (ii) the registration of such shares of Common Stock under the
      Securities Act and the Exchange Act, in each case, if required; or
      availability of an exemption from such registration;


                                       20







            (iii) the approval for listing of such shares of Common Stock on a
      national securities exchange or the approval for quotation of such shares
      of Common Stock in an inter-dealer quotation system of any registered
      United States national securities association;

            (iv) any necessary qualification or registration under applicable
      state securities laws or the availability of an exemption from such
      qualification and registration; and

            (v) The receipt by the Trustee of an Officers' Certificate and an
      Opinion of Counsel each stating that (A) the terms of the issuance of the
      shares of Common Stock are in conformity with the Indenture and (B) the
      shares of Common Stock to be issued by the Company in payment of the
      Purchase Price in respect of Senior Notes have been duly authorized and,
      when issued and delivered pursuant to the terms of the Indenture in
      payment of the Purchase Price in respect of the Senior Notes, will be
      validly issued, fully paid and non-assessable and, to the best of such
      counsel's knowledge, free from preemptive rights, and, in the case of such
      Officers' Certificate, stating that the conditions above and the condition
      set forth in the second succeeding sentence have been satisfied and, in
      the case of such Opinion of Counsel, stating that, to such counsel's
      knowledge, the conditions in clauses (ii) through (iv) above have been
      satisfied. Such Officers' Certificate shall also set forth the number of
      shares of Common Stock to be issued for each $1,000 principal amount of
      Senior Notes and the Closing Price of a share of Common Stock on each
      Trading Day during the period commencing on the first Trading Day of the
      period during which the Market Price is calculated and ending on the third
      Business Day prior to the applicable Subsequent Purchase Date.

      If the foregoing conditions are not satisfied with respect to a Holder or
Holders prior to the close of business on the last day prior to the Subsequent
Purchase Date and the Company has elected to purchase the Senior Notes pursuant
to this Section 3.08 through the issuance of shares of Common Stock, the Company
shall pay the entire Purchase Price of the Senior Notes of such Holder or
Holders in cash.

      Upon determination of the actual number of shares of Common Stock to be
issued upon redemption or repurchase of Senior Notes, the Company shall be
required to disseminate a press release through Dow Jones & Company, Inc. or
Bloomberg Business News containing this information or publish the information
on the Company's Web site or through such other public medium as the Company may
use at that time.

      Any determination that the Company or the Board of Directors must make
pursuant to Article 3 shall be conclusive, absent mathematical error.






                                       21


      (d) Notice of Election. In connection with any purchase of Senior Notes
pursuant to Section 3.06, the Company shall give notice to Holders setting forth
information specified in this Section 3.08(d) (the "COMPANY NOTICE").

      In the event the Company has elected to pay the Purchase Price (or a
specified percentage thereof), with shares of Common Stock, the Company Notice
shall:

            (i) state that each Holder will receive a number of shares of Common
      Stock equal to the quotient obtained by dividing (i) the portion of the
      Purchase Price to be paid in shares of Common Stock, which portion must be
      $1,000 or an integral multiple of $1,000, by (ii) 100% of the Market Price
      (except any cash amount to be paid in lieu of fractional shares);

            (ii) set forth the method of calculating the Market Price of the
      shares of Common Stock; and

            (iii) state that because the Market Price of shares of Common Stock
      will be determined prior to the Subsequent Purchase Date, Holders of the
      Senior Notes will bear the market risk with respect to the value of the
      shares of Common Stock to be received from the date such Market Price is
      determined to the Purchase Date.

      In any case, each Company Notice shall include a form of Purchase Notice
to be completed by a Holder and shall state:

            (i) the Purchase Price and the Conversion Rate;

            (ii) the name and address of the Paying Agent and the Conversion
      Agent;

            (iii) that Senior Notes as to which a Purchase Notice has been given
      may be converted if they are otherwise convertible only in accordance with
      Article 5 hereof and Section 8 of the Senior Notes if the applicable
      Purchase Notice has been withdrawn in accordance with the terms of the
      Indenture;

            (iv) that Senior Notes must be surrendered to the Paying Agent to
      collect payment;

            (v) that the Purchase Price for any Senior Note as to which a
      Purchase Notice has been given and not withdrawn will be paid promptly
      following the later of the Purchase Date and the time of surrender of such
      Senior Notes as described in (iv);



                                       22


            (vi) the procedures the Holder must follow to exercise its right to
      require the Company to repurchase Senior Notes under Section 3.06 and a
      brief description of those rights; (vii) briefly, the conversion rights,
      if any, with respect to the Senior Notes;

            (vii) briefly, the conversion rights, if any, with respect to the
      Senior Notes;

            (viii) the procedures for withdrawing a Purchase Notice (including,
      without limitation, for a conditional withdrawal pursuant to the terms of
      Section 3.06(i)(D) or Section 3.11);

            (ix) that, unless the Company defaults in making payment on Senior
      Notes for which a Purchase Notice has been submitted, Interest on such
      Senior Notes will cease to accrue on and after the Purchase Date; and

            (x) the CUSIP number of the Senior Notes.

      At the Company's request, the Trustee shall give such Company Notice in
the Company's name and at the Company's expense; provided, however, that, in all
cases, the text of such Company Notice shall be prepared by the Company.

      Section 3.09. Covenants of the Company. All shares of Common Stock
delivered upon purchase of the Senior Notes shall be newly issued shares or
treasury shares, shall be duly authorized, validly issued, fully paid and
nonassessable, and shall be free from preemptive rights and free of any lien or
adverse claim.

      Section 3.10. Taxes. If a Holder of a purchased Senior Note is paid in
shares of Common Stock, the Company shall pay any documentary, stamp or similar
issue or transfer tax due on such issue of Common Stock; provided that the
Holder shall pay any such tax which is due because the Holder requests the
Common Stock to be issued in a name other than the Holder's name. The Paying
Agent may refuse to deliver the certificates representing the shares of Common
Stock being issued in a name other than the Holder's name until the Paying Agent
receives a sum sufficient to pay any tax which will be due because the shares of
Common Stock are to be issued in a name other than the Holder's name. Nothing
herein shall preclude any income tax withholding required by law or regulations.

      Section 3.11. Effect of Purchase Notice or Fundamental Change Purchase
Notice. (a) Upon receipt by the Paying Agent of the Purchase Notice or
Fundamental Change Purchase Notice specified in Section 3.06(i) or Section
3.07(c), as applicable, the Holder of the Senior Note in respect of which such

Fundamental Change Purchase Price, as the case may be, with respect to such
Senior Note. Such Purchase Price or Fundamental Change Purchase Price shall be
paid to such Holder, subject to receipts of funds and/or securities by the
Paying Agent, promptly following the later of (x) the Purchase Date or the
Fundamental Change Purchase Date, as the case may be, with respect to such
Senior Notes (provided the conditions in Section 3.06(i) or Section 3.07(c), as
applicable, have been satisfied) and (y) the time of delivery of such Senior
Note to the Paying Agent by the Holder thereof in the manner required by Section
3.06 or Section 3.07(c), as applicable. Senior Notes in respect of which a
Purchase Notice or Fundamental Change Purchase Notice has been given by the
Holder thereof may not be converted pursuant to Article 5 hereof on or after the
date of the delivery of such Purchase Notice or Fundamental Change Purchase
Notice unless such Purchase Notice or Fundamental Change Purchase Notice has
first been validly withdrawn as specified in the following two paragraphs.

      (b) A Purchase Notice or Fundamental Change Purchase Notice may be
withdrawn by means of a written notice of withdrawal delivered to the office of
the Paying Agent in accordance with the Purchase Notice or Fundamental Change
Purchase Notice, as the case may be, at any time prior to the close of business

      Purchase Notice, as the case may be, and which has been or will be
      delivered for purchase by the Company.

      (c) A written notice of withdrawal of a Purchase Notice may be in the form
set forth in Section 3.11(b) or may be in the form of (i) a conditional
withdrawal contained in a Purchase Notice pursuant to the terms of Section
3.06(i)(D) or (ii) a conditional withdrawal containing the information set forth
in Section 3.06(i)(D) and Section 3.11(b) and contained in a written notice of
withdrawal delivered to the Paying Agent as set forth in Section 3.11(b).

      (d) A written notice of withdrawal of a Fundamental Change Purchase Notice
may be in the form set forth in Section 3.11(b).



                                       24


      (e) There shall be no purchase of any Senior Notes pursuant to Section
3.06 or 3.07 if there has occurred (prior to, on or after, as the case may be,
the giving, by the Holders of such Senior Notes, of the required Purchase Notice
or Fundamental Change Purchase Notice, as the case may be) and is continuing an
Event of Default (other than a default in the payment of the Purchase Price or
Fundamental Change Purchase Price, as the case may be, with respect to such
Senior Notes). The Paying Agent will promptly return to the respective Holders
thereof any Senior Notes (x) with respect to which a Purchase Notice or
Fundamental Change Purchase Notice, as the case may be, has been withdrawn in
compliance with the Indenture, or (y) held by it during the continuance of an
Event of Default (other than a default in the payment of the Purchase Price or
Fundamental Change Purchase Price, as the case may be, with respect to such
Senior Notes) in which case, upon such return, the Purchase Notice or
Fundamental Change Purchase Notice with respect thereto shall be deemed to have
been withdrawn.

      Section 3.12. Deposit of Purchase Price or Fundamental Change Purchase
Price. On or prior to 10:00 a.m. (New York City time) on the Purchase Date or
the Fundamental Change Purchase Date, as the case may be, the Company shall
deposit with the Trustee or with the Paying Agent (or, if the Company or a
Subsidiary or an Affiliate of either of them is acting as the Paying Agent,
shall segregate and hold in trust as provided in Article 10 of the Base
Indenture) an amount of cash (in immediately available funds if deposited on
such Business Day) or Common Stock, if permitted hereunder, sufficient to pay
the aggregate Purchase Price or Fundamental Change Purchase Price, as the case
may be, of all the Senior Notes or portions thereof which are to be purchased as
of the Purchase Date or Fundamental Change Purchase Date, as the case may be.
Upon such deposit and immediately after the Purchase Date or Fundamental Change
Purchase Date, as the case may be, (i) such Senior Notes shall cease to be
outstanding and Interest on such Senior Notes will cease to accrue, whether or
not such Senior Notes are delivered to the Paying Agent for payment and (ii) all
other rights under the Indenture of Holders of such Senior Notes shall
terminate, other than the right to receive the Purchase Price or the Fundamental
Change Purchase Price, as the case may be, in accordance with the provisions of
the Indenture.

      As soon as practicable after the Purchase Date, the Company shall deliver
to each Holder entitled to receive shares of Common Stock through the Paying
Agent, a certificate for the number of full shares of Common Stock issuable in
payment of the Purchase Price, and cash in lieu of any fractional interests. The
person in whose name the certificate for the shares of Common Stock is
registered shall be treated as a holder of record of Common Stock on the
Business Day following the Purchase Date. Subject to Section 3.08(c), no payment
or adjustment will be made for dividends on the shares of Common Stock the
record date for which occurred on or prior to the Purchase Date.



                                       25

      Section 3.13. Senior Notes Purchased in Part. Any Certificated Senior Note
which is to be purchased only in part shall be surrendered at the office of the
Paying Agent (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Senior Note, without service
charge, a new Senior Notes or Senior Notes, of any authorized denomination as
requested by such Holder in aggregate principal amount equal to, and in exchange
for, the portion of the principal amount of the Senior Note so surrendered which
is not purchased.

      Section 3.14. Covenant to Comply with Securities Laws upon Purchase of
Senior Notes. When complying with the provisions of Section 3.06 or 3.07 hereof
(provided that such offer or purchase constitutes an "ISSUER TENDER OFFER" for
purposes of Rule 13e-4 (which term, as used herein, includes any successor
provision thereto) under the Exchange Act at the time of such offer or
purchase), and subject to any exemptions available under applicable law, the
Company shall (i) comply with Rule 13e-4 and Rule 14e-1 (or any successor
provision) under the Exchange Act, (ii) file the related Schedule TO (or any
successor schedule, form or report) under the Exchange Act, and (iii) otherwise
comply with all Federal and state securities laws so as to permit the rights and
obligations under Sections 3.06 and 3.07 to be exercised in the time and in the
manner specified in Sections 3.06 and 3.07 (to the extent that such time and
manner so specified comply with such laws then in effect).

      Section 3.15. Repayment to the Company. The Trustee and the Paying Agent
shall return to the Company any cash or shares of Common Stock that remain
unclaimed as provided in Section 13 of the Senior Notes, together with interest
or dividends, if any, thereon (subject to the provisions of Article 10 of the
Base Indenture) held by them for the payment of the Purchase Price or
Fundamental Change Purchase Price, as the case may be; provided, however, that
to the extent that the aggregate amount of cash or shares of Common Stock
deposited by the Company pursuant to Section 3.12 exceeds the aggregate Purchase
Price or Fundamental Change Purchase Price, as the case may be, of the Senior
Notes or portions thereof which the Company is obligated to purchase as of the
Purchase Date or Fundamental Change Purchase Date, as the case may be, then,
unless otherwise agreed in writing with the Company, promptly after the Business
Day following the Purchase Date or Fundamental Change Purchase Date, as the case
may be, the Trustee shall return any such excess to the Company together with
interest or dividends, if any, thereon (subject to the provisions of Article 6
of the Base Indenture).



                                       26


                                   Article 4
                                Events Of Default

      Section 4.01. Events of Default. Each of the following shall constitute an
Event of Default with respect to the Senior Notes:

      (a) the Company fails to convert any portion of the principal amount of

      (g) a failure to pay when due at maturity or a default, event of default
or other similar condition or event (however described) that results in the
acceleration of maturity of any indebtedness for borrowed money of the Company

unless the acceleration is rescinded, stayed or annulled within 30 days after
written notice of default is given to the Company by the Trustee or Holders of
not less than 25% in aggregate principal amount of the Senior Notes then
outstanding;

      (h) the entry by a court having jurisdiction in the premises of (i) a
decree or order for relief in respect of the Company or any of its Designated
Subsidiaries or any group of two or more Subsidiaries that, taken as a whole,
would constitute a Designated Subsidiary, in an involuntary case or proceeding
under any applicable bankruptcy, insolvency, reorganization or other similar law



                                       27


or (ii) a decree or order adjudging the Company or any of its Designated
Subsidiaries or any group of two or more Subsidiaries that, taken as a whole,

as properly filed a petition seeking reorganization, arrangement, adjustment or
composition of or in respect of the Company or any of its Designated

property, or ordering the winding up or liquidation of its affairs, and the
continuance of any such decree or order for relief or any such other decree or
order unstayed and in effect for a period of 60 consecutive days; and

      (i) the commencement by the Company or any of its Designated Subsidiaries
or any group of two or more Subsidiaries that, taken as a whole, would
constitute a Designated Subsidiary, of a voluntary case or proceeding under any
applicable bankruptcy, insolvency, reorganization or other similar law or of any
other case or proceeding to be adjudicated a bankrupt or insolvent, or the
consent by the Company or any of its Designated Subsidiaries or any group of two

bankruptcy or insolvency case or proceeding against the Company, or the filing
by the Company or any of its Designated Subsidiaries or any group of two or more
Subsidiaries that, taken as a whole, would constitute a Designated Subsidiary,
of a petition or answer or consent seeking reorganization or relief under any

that, taken as a whole, would constitute a Designated Subsidiary, of an
assignment for the benefit of creditors, or the admission by the Company or any
of its Designated Subsidiaries or any group of two or more Subsidiaries that,
taken as a whole, would constitute a Designated Subsidiary, in writing of its

corporate action by the Company or any of its Subsidiaries that is a Designated
Subsidiary or any group of two or more Subsidiaries that, taken as a whole,
would constitute a Designated Subsidiary, expressly in furtherance of any such
action.

      For the avoidance of doubt, clause (f) above shall not constitute an Event
of Default until the Trustee notifies the Company, or the Holders of at least
25%



                                       28


in aggregate principal amount of the Senior Notes at the time outstanding notify
the Company and the Trustee, of such default and the Company does not cure such
default (and such default is not waived) within the time specified in clause (f)
above after actual receipt of such notice. Any such notice must specify the
default, demand that it be remedied and state that such notice is a "NOTICE OF
Default."

      The Trustee shall, within 90 days of the occurrence of an Event of
Default, give to the Holders of the Senior Notes notice of all uncured Events of
Defaults known to it and written notice of any event which with the giving of
notice or the lapse of time, or both, would become an Event of Default, its
status and what action the Company is taking or proposes to take with respect
thereto; provided, however, the Trustee shall be protected in withholding such
notice if it, in good faith, determines that the withholding of such notice is
in the best interest of such Holders, except in the case of an Event of Default
specified in clauses (a) through (e) of this Section 4.01.

      The Company shall furnish annually to the Trustee a statement as to the
fulfillment of the Company's obligation under the Indenture.

      Section 4.02. Acceleration. If an Event of Default (other than an Event of
Default specified in Section 4.01(h) or 4.01(i)) occurs and is continuing, the
Trustee by notice to the Company, or the Holders of at least 25% in aggregate
principal amount of the Senior Notes at the time outstanding by notice to the
Company and the Trustee, may declare the principal amount of the Securities and
any accrued and unpaid Interest, if any, on all the Senior Notes to be
immediately due and payable. Upon such a declaration, such accelerated amount
shall be due and payable immediately. If an Event of Default specified in
Section 4.01(h) or 4.01(i) occurs and is continuing, the principal amount of the
Senior Notes and any accrued and unpaid Interest, if any, on all the Senior
Notes shall become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holders. The Holders of a majority
in aggregate principal amount of the Senior Notes at the time outstanding, by
notice to the Trustee (and without notice to any other Holder) may rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived except nonpayment of the principal amount of the Senior Notes and any
accrued and unpaid Interest, if any, that have become due solely as a result of
acceleration and if all amounts due to the Trustee under Section 6.07 of the
Base Indenture have been paid. No such rescission shall affect any subsequent
Event of Default or impair any right consequent thereto.



                                       29


                                   Article 5
                                   Conversion

      Section 5.01. Right to Convert. (a) Holders of the Senior Notes may not
convert their Senior Notes prior to February 17, 2005. On or after February 17,
2005, subject to and upon compliance with the provisions of this Article 5, a
Holder of any Senior Notes shall have the right, at such Holder's option, to
convert the principal amount of the Senior Notes, or any portion of such
principal amount which is a multiple of $1,000, at any time prior to the close
of business on the Stated Maturity into fully paid and nonassessable shares of
Common Stock (as such shares shall then be constituted) at the Conversion Rate
in effect at such time, by surrender of the Senior Notes so to be converted in
whole or in part, together with any required funds, only under the circumstances
described in this Section 5.01 and in the manner provided in Section 5.02.

      Notwithstanding any other provision of the Senior Notes or the Indenture,
all Holders' rights with respect to conversion of the Senior Notes and the
Company's obligation to deliver shares of Common Stock at the Conversion Rate
upon such conversion (the "CONVERSION OBLIGATION"), are subject, in their
entirety, to the Company's right, in its sole and absolute discretion, to elect
to satisfy such Conversion Obligation in any manner permitted pursuant to
Section 5.03.

      (b) On or after February 17, 2005, Senior Notes may be surrendered for
conversion into shares of Common Stock in integral multiples of $1,000 principal
amount during any fiscal quarter of the Company (and only during such fiscal
quarter), if the Closing Price of the Common Stock for at least 20 Trading Days
in the 30 consecutive Trading Day period ending on the last Trading Day of the
previous fiscal quarter is greater than or equal to 130% of the Conversion Price
in effect on that 30th Trading Day.

      (c) Any Senior Notes called for redemption under Article 3 hereof may be
surrendered for conversion into shares of Common Stock in integral multiples of
$1,000 principal amount at any time prior to the close of business on the
Business Day immediately preceding the Redemption Date, even if the Senior Notes
are not otherwise convertible at such time.

      (d) Senior Notes may be surrendered for conversion into shares of Common
Stock in integral multiples of $1,000 principal amount:

            (i) if the Company elects to distribute to all holders of Common
      Stock:

                  (A) rights or warrants entitling them to purchase, for a
            period expiring within 60 days of the date of such distribution,



                                       30


            Common Stock at less than the Closing Price of the Common Stock on
            the record date for such distribution or

                  (B) assets, debt securities or rights to purchase the
            Company's securities, which distribution has a per share value as
            determined by the Board of Directors exceeding 10% of the Closing
            Price of the Common Stock on the Trading Day immediately preceding
            the declaration date for such distribution

beginning on the date that the Company gives notice to the Holders of such
right, which shall not be less than 22 Business Days prior to the Ex-Dividend
Date for such distribution; Senior Notes may be surrendered for conversion at
any time thereafter until the earlier of the close of business on the Business
Day prior to the Ex-Dividend Date or the date the Company announces that such
dividend or distribution will not take place; provided that Holders shall not
have the right to surrender Senior Notes for conversion pursuant to this Section
5.01(d)(i) if they will otherwise participate in the distribution described
above without first converting Senior Notes into Common Stock; or

            (ii) if the Company is a party to a consolidation, merger or binding
      share exchange or transfer of all or substantially all of the Company's
      assets pursuant to which shares of Common Stock would be converted into
      cash, securities or other property, at any time from and after the date
      that is 15 days prior to the anticipated effective date of the transaction
      until 15 days after the actual effective date of such transaction (or, if
      such transaction constitutes a Fundamental Change, until the Business Day
      immediately proceeding the applicable Fundamental Change Purchase Date)
      and, at the effective time of the transaction, the right to convert a
      Senior Note into shares of Common Stock shall be changed into a right to
      convert such Senior Note into the kind and amount of cash, securities or
      other property of the Company or another person that the Holder would have
      received if the Holder had converted such Senior Note immediately prior to
      applicable record date for the transaction.

      Upon determination that Holders are or will be entitled to convert the
Senior Notes, the Company shall disseminate a press release through Dow Jones &
Company, Inc. or Bloomberg Business News and publish such information on the
Company's Web site as soon as practicable, and the Company or its designated
agents shall promptly deliver to the Trustee and the Conversion Agent written
notice thereof. Any notice so given shall be conclusively presumed to have been
duly given, whether or not the Holder receives such notice.

      Section 5.02. Conversion Procedures. To convert a Senior Note, a Holder
must (a) complete and manually sign the Notice of Conversion or a facsimile of
the Notice of Conversion on the back of the Senior Note (the "NOTICE



                                       31


OF CONVERSION") or a facsimile thereof and have such notice delivered to the
Conversion Agent, (b) surrender the Senior Note to the Conversion Agent, (c)
furnish appropriate endorsements and transfer documents if required by the
Security Registrar or the Conversion Agent, (d) if required, pay all transfer or
similar taxes and (e) if required, pay funds equal to the Interest payable on
the next Interest Payment Date. To convert a beneficial interest in the Senior
Note, the Holder thereof must comply with clauses (c) through (e) of the
preceding sentence through the Depositary's procedures for conversion. The date
on which the Holder satisfies all of those requirements is the "CONVERSION
DATE."

      The Company will, on the Conversion Settlement Date, (i) pay the cash
component (including cash in lieu of any fraction of a share to which such
Holder would otherwise be entitled), if any, of the Conversion Settlement
Distribution determined pursuant to Section 5.03 to the Holder of a Senior Note
surrendered for conversion, or such Holder's nominee or nominees, and (ii)
issue, or cause to be issued, and deliver to the Conversion Agent or to such
Holder, or such Holder's nominee or nominees, certificates for the number of
full shares of Common Stock, if any, to which such Holder shall be entitled as
part of such Conversion Settlement Distribution (in the case of Senior Notes
held in book-entry form with the Depositary, shares shall be delivered in
accordance with the Depositary's customary procedures).

      The Person in whose name the Common Stock certificate is registered shall
be deemed to be a shareholder of record at the close of business on the
applicable Conversion Settlement Date; provided however, that if any such date
is a date when the stock transfer books of the Company are closed, such Person
shall be deemed a shareholder of record as of the next date on which the stock
transfer books of the Company are open.

      No payment or adjustment shall be made for dividends on, or other
distributions with respect to, any Common Stock except as provided in this
Article 5. On conversion of a Senior Note, any accrued and unpaid interest with
respect to such Senior Note that is attributable to the period from the Issue
Date to the Conversion Date shall not be cancelled, extinguished or forfeited
but rather shall be deemed paid in full to the Holder of such Senior Note
through the delivery of the Common Stock (together with the cash payment, if
any, in lieu of fractional shares), or cash or a combination of cash and Common
Stock in lieu thereof, in exchange for the Senior Note being converted pursuant
to the provisions hereof, and the fair market value of the Common Stock
(together with the cash payment, if any, in lieu of fractional shares), or cash
or a combination of cash and Common Stock in lieu thereof, shall be treated as
issued, to the extent thereof, first in exchange for any accrued and unpaid
interest attributable to the period from the Issue Date to the Conversion Date,
and the balance, if any, of such fair market value shall be treated as issued in
exchange for the principal amount of the Senior Note being converted pursuant to
the provisions hereof.



                                       32


Notwithstanding the preceding sentence, on conversion of a Senior Note during
the period from the close of business on any Regular Record Date immediately
preceding any Interest Payment Date to the close of business on the Business Day
immediately preceding such Interest Payment Date, the Holder on such Regular
Record Date shall receive the Interest payable on such Interest Payment Date.

      If a Holder converts more than one Senior Note at the same time, the
number of shares of Common Stock issuable upon the conversion shall be based on
the aggregate principal amount of Senior Notes converted.

      Upon surrender of a Senior Note that is converted in part, the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder, a
new Senior Note equal in principal amount to the principal amount of the
unconverted portion of the Senior Note surrendered.

      Senior Notes or portions thereof surrendered for conversion during the
period from the close of business on any Regular Record Date immediately
preceding any Interest Payment Date to the close of business on the Business Day
immediately preceding such Interest Payment Date shall be accompanied by payment
to the Company or its order, in New York Clearing House funds or other funds
acceptable to the Company, of an amount equal to the Interest payable on such
Interest Payment Date with respect to the principal amount of Senior Notes or
portions thereof being surrendered for conversion; provided that no such payment
need be made if (1) the Company has specified a Redemption Date that occurs
during the period from the close of business on a Regular Record Date to the
close of business on the Interest Payment Date to which such Regular Record Date
relates, (2) the Company has specified a Fundamental Change Purchase Date during
such period or (3) only to the extent of overdue Interest, any overdue Interest
exists on the Conversion Date with respect to the Senior Notes converted.

      Section 5.03. Payment of Cash in Lieu of Common Stock.

      (a) If a Holder elects to convert all or any portion of a Senior Note into
shares of Common Stock as set forth in Section 5.01 and the Company receives
such Holder's Notice of Conversion on or prior to the day that is 10 days prior
to the Stated Maturity, or with respect to Senior Notes called for redemption
pursuant to Article 3 hereof, the applicable Redemption Date (the "FINAL NOTICE
DATE"), the Company may choose to satisfy all or any portion of the Conversion
Obligation in cash. Upon such election, the Company will notify such Holder
through the Trustee of the dollar amount to be satisfied in cash (which must be
expressed either as 100% of the Conversion Obligation or as a fixed dollar
amount) at any time on or before the date that is two Business Days following
the Conversion Agent's receipt of the Notice of Conversion (such period, the
"CASH SETTLEMENT NOTICE PERIOD"). If the Company elects to pay cash for any
portion of the shares of Common Stock otherwise issuable to the Holder, the
Holder may



                                       33


retract the Notice of Conversion at any time during the two Business Day period
beginning on the day after the final day of the Cash Settlement Notice Period
(the "CONVERSION RETRACTION PERIOD"); no such retraction can be made (and a
Notice of Conversion shall be irrevocable) if the Company does not elect to
deliver cash in lieu of shares of Common Stock (other than cash in lieu of
fractional shares). If the Company elects to satisfy all or a portion of its
Conversion Obligations in cash and the Notice of Conversion has not been
retracted, then settlement (in cash or a combination of cash and shares) will
occur on the third Business Day following the Cash Settlement Averaging Period.
If the Company elects to satisfy the entire Conversion Obligation in shares of
Common Stock, then settlement will occur on the third Business Day following the
Conversion Date. With respect to any Notice of Conversion received by the
Company prior to the Final Notice Date and not retracted pursuant to this
Section 5.03(a), the "CONVERSION SETTLEMENT DISTRIBUTION" for any Senior Note
subject to such Notice of Conversion shall consist of cash, Common Stock or a
combination thereof, as selected by the Company as set forth below:

            (i) if the Company elects to satisfy the entire Conversion
      Obligation in shares of Common Stock, the Conversion Settlement
      Distribution shall be a number of shares of Common Stock for each $1,000
      principal amount of the Senior Notes to be converted equal to the
      Conversation Rate, plus cash for any fractional shares pursuant to Section
      5.04;

            (ii) if the Company elects to satisfy the entire Conversion
      Obligation in cash, the Conversion Settlement Distribution shall be cash
      for each $1,000 principal amount of the Senior Notes in an amount equal to
      the product of:

                  (A) the applicable Conversion Rate, and

                  (B) the average of the Closing Prices of the Common Stock for
            the 10 Trading Days beginning on the Trading Day immediately
            following the final day of the Conversion Retraction Period (the
            "CASH SETTLEMENT AVERAGING PERIOD"); and

            (iii) if the Company elects to satisfy a fixed portion (other than
      100%) of the Conversion Obligation in cash, the Conversion Settlement
      Distribution shall consist of such cash amount ("CASH AMOUNT") and a
      number of shares, for each $1,000 principal amount of the Senior Notes,
      equal to the applicable Conversion Rate minus the number of shares of
      Common Stock equal to the Cash Amount divided by the average Closing Price
      of the Common Stock during the Cash Settlement Averaging Period (plus cash
      for any fractional shares pursuant to Section 5.04); provided,



                                       34


      however, the number of shares of Common Stock shall not be less than zero.

      (b) At any time on or before any Final Notice Date, the Company will
notify the Trustee whether it intends to satisfy all or any portion of the
Conversion Obligation with respect to conversions of Senior Notes for which the
Company receives a Notice of Conversion after such Final Notice Date and the
dollar amount to be satisfied in cash (which must be expressed either as 100% or
as a fixed dollar amount). In such case, the applicable Conversion Settlement
Distribution will be computed in the same manner as set forth in clause (a)
above except that the Cash Settlement Averaging Period shall be the 10 Trading
Days beginning on the Trading Day following the Company's receipt of the Notice
of Conversion, and settlement (in cash or a combination of cash and shares) will
occur on the third Business Day following the final day of such Cash Settlement
Averaging Period (which date could be after Stated Maturity).

      (c) Notwithstanding anything to the contrary in the Indenture, at any time
prior to Stated Maturity, the Company may irrevocably elect, in its sole
discretion without the consent of the Holders of the Senior Notes, by notice to
the Trustee and the Holders of the Senior Notes, to satisfy a portion of the
Conversion Obligation for all Senior Notes for conversion after the date of such
election (the "ELECTION DATE") by paying in cash up to 100% of the principal
amount of the Senior Notes so converted. After making such an election, the
Company shall satisfy the remainder of the Conversion Obligation in Common
Stock, to the extent the Conversion Obligation exceeds the principal amount. In
the event that the Company receives a Notice of Conversion after the Election
Date: the Notice of Conversion will not be retractable; the Cash Settlement
Averaging Period shall be the 10 Trading Day period beginning on the day after
the Company's receipt of the Notice of Conversion; and the Conversion Settlement
Distribution for each $1,000 principal amount of the Senior Notes shall consist
of (i) such cash amount ("ELECTION AMOUNT") equal to the applicable Conversion
Rate multiplied by the average Closing Price of Common Stock during the Cash
Settlement Averaging Period (provided, however, that the Election Amount will
not be more than 100% of the principal amount of a Senior Note) and (ii) a
number of shares of Common Stock equal to the applicable Conversation Rate minus
the Election Amount divided by the average Closing Price of the Common Stock
during the Cash Settlement Averaging Period.

      Section 5.04. Fractional Shares. The Company shall not issue a fractional
share of Common Stock upon conversion of a Senior Note. Instead, the Company
will deliver cash for the current market value of the fractional share. The
current market value of a fractional share of Common Stock shall be determined,
to the nearest 1/1,000th of a share, by multiplying the Closing Price of a full
share of Common Stock on the Trading Day immediately preceding the



                                       35


Conversion Date by the fractional amount and rounding the product to the nearest
whole cent.

      Section 5.05. Taxes on Conversion. If a Holder converts a Senior Note,
the Company shall pay any documentary, stamp or similar issue or transfer taxes
due on the issue of shares of Common Stock upon such conversion. However, 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 5.06. Reservation of Shares, Shares to be Fully Paid; Compliance
with Governmental Requirements; Listing of Common Stock.

      (a) The Company shall provide, free from preemptive rights, out of its
authorized but unissued shares or shares held in treasury, sufficient shares of
Common Stock to provide for the conversion of the Senior Notes from time to time
as such Senior Notes are presented for conversion.

      (b) Before taking any action which would cause an adjustment increasing
the Conversion Rate to an amount that would cause the Conversion Price to be
reduced below the then par value, if any, of the shares of Common Stock issuable
upon conversion of the Senior Notes, the Company will take all corporate action,
if any, which may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue shares of such Common Stock at such
adjusted Conversion Rate.

      (c) (i) The Company covenants that all shares of Common Stock which may be
issued upon conversion of Senior Notes will upon issue be fully paid and
nonassessable by the Company and, subject to the provisions of Section 5.05,
free from all taxes, liens and charges with respect to the issue thereof.

            (ii) The Company covenants that, if any shares of Common Stock to be
      provided for the purpose of conversion of Senior Notes hereunder require
      registration with or approval of any governmental authority under any
      federal or state law before such shares may be validly issued upon
      conversion, the Company will in good faith and expeditiously, to the
      extent then permitted by the rules and interpretations of the Securities
      and Exchange Commission (or any successor thereto), endeavor to secure
      such registration or approval, as the case may be.



                                       36

      (d) The Company further covenants that, if at any time the Common Stock
shall be listed on the New York Stock Exchange or any other national securities
exchange or automated quotation system, the Company will, if permitted by the
rules of such exchange or automated quotation system, list and keep listed, so
long as the Common Stock shall be so listed on such exchange or automated
quotation system, all Common Stock issuable upon conversion of the Senior Note;
provided, however, that, if the rules of such exchange or automated quotation
system permit the Company to defer the listing of such Common Stock until the
first conversion of the Senior Notes into Common Stock in accordance with the
provisions of the Indenture, the Company covenants to list such Common Stock
issuable upon conversion of the Senior Notes in accordance with the requirements
of such exchange or automated quotation system at such time.

      Section 5.07. Adjustment of Conversion Rate. The Conversion Rate shall be
adjusted from time to time by the Company as follows:

      (a) In case the Company shall hereafter pay a dividend or make a
distribution to all holders of the outstanding Common Stock in shares of Common
Stock, the Conversion Rate shall be increased so that the same shall equal the
rate determined by multiplying the Conversion Rate in effect at the opening of
business on the date following the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution by a
fraction,

            (i) the numerator of which shall be the sum of the number of shares
      of Common Stock outstanding at the close of business on the date fixed for
      the determination of stockholders entitled to receive such dividend or
      other distribution plus the total number of shares of Common Stock
      constituting such dividend or other distribution; and

            (ii) the denominator of which shall be the number of shares of
      Common Stock outstanding at the close of business on the date fixed for
      such determination,

such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. If any dividend or
distribution of the type described in this Section 5.07(a) 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.

      (b) In case the Company shall issue rights or warrants to all holders of
its outstanding shares of Common Stock entitling them (for a period expiring
within sixty (60) days after the date fixed for determination of stockholders
entitled to receive such rights or warrants) to subscribe for or purchase shares
of Common Stock at a price per share less than the Closing Price on the record
date for the distribution, the Conversion Rate shall be increased so that the
same shall


                                       37

equal the rate determined by multiplying the Conversion Rate in effect
immediately prior to the date fixed for determination of stockholders entitled
to receive such rights or warrants by a fraction,

            (i) the numerator of which shall be the number of shares of Common
      Stock outstanding on the date fixed for determination of stockholders
      entitled to receive such rights or warrants plus the total number of
      additional shares of Common Stock offered for subscription or purchase;
      and

            (ii) the denominator of which shall be the sum of the number of
      shares of Common Stock outstanding at the close of business on the record
      date fixed for determination of stockholders entitled to receive such
      rights or warrants plus the number of shares that the aggregate offering
      price of the total number of shares so offered would purchase at a price
      equal to the Closing Price as of the date immediately preceding the record
      date fixed for determination of stockholders entitled to receive such
      rights or warrants.

      Such adjustment shall be successively made whenever any such rights or
warrants are issued, and shall become effective immediately after the opening of
business on the day following the date fixed for determination of stockholders
entitled to receive such rights or warrants. To the extent that shares of Common
Stock are not delivered after the expiration of such rights 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 or warrants
been made on the basis of delivery of only the number of shares of Common Stock
actually delivered. If such rights 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 such date fixed for the determination of stockholders entitled to
receive such rights or warrants had not been fixed. In determining whether any
rights or warrants entitle the holders to subscribe for or purchase shares of
Common Stock at a price less than the Closing Price on the record date for the
distribution, and in determining the aggregate offering price of such shares of
Common Stock, there shall be taken into account any consideration received by
the Company for such rights 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.

      (c) In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the day following the day upon which such subdivision
becomes effective shall be proportionately increased, and conversely, in case
outstanding shares of Common Stock shall be combined into a smaller number of
shares of Common Stock, the Conversion Rate in effect at the opening


                                       38

of business on the day following the day upon which such combination becomes
effective shall be proportionately reduced, such increase or reduction, as the
case may be, to become effective immediately after the opening of business on
the day following the day upon which such subdivision or combination becomes
effective.

      (d) (A) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock shares of any class of capital stock, evidences
of indebtedness or assets, including securities, but excluding (x) any dividend
or distribution or issuance referred to in Section 5.07(a) or (b) and (y) any
dividend or distribution paid exclusively in cash (any of the foregoing
hereinafter in this Section 5.07(d) called the "DISTRIBUTED ASSETS OR
SECURITIES"), then, in each such case, 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 Regular Record Date with respect to such
distribution by a fraction,

            (i) the numerator of which shall be the Current Market Price on such
      Regular Record Date; and

            (ii) the denominator of which shall be the Current Market Price on
      such Regular Record Date less the Fair Market Value (as determined by the
      Board of Directors, whose determination shall be conclusive, and described
      in a resolution of the Board of Directors) on the Regular Record Date of
      the portion of the Distributed Assets or Securities so distributed
      applicable to one share of Common Stock,

such adjustment to become effective immediately prior to the opening of business
on the day following such Regular Record Date. If 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. If the Board of Directors determines the Fair Market
Value of any distribution for purposes of this Section 5.07(d) 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 on the applicable Regular Record Date.

      Rights or warrants distributed by the Company to all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights or warrants, until the occurrence of a specified event or events
("TRIGGER EVENT"): (i) are deemed to be transferred with such shares of Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future
issuances of Common Stock, shall be deemed not to have been distributed for
purposes of this Section 5.07 (and no adjustment to the Conversion Rate under
this Section 5.07 will be required) until the occurrence of the earliest Trigger
Event, whereupon


                                       39

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 Section 5.07(d). If any such right or warrant, including any such
existing rights or warrants distributed prior to the date of the 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 5.07 was made, (1) in the case of any such rights or warrants that shall
all have been redeemed or repurchased without exercise by any holders thereof,
the Conversion Rate shall be readjusted upon such final redemption or repurchase
to give effect to such distribution or Trigger Event, as the case may be, as
though it were a cash distribution, equal to the per share redemption or
repurchase price received by a holder 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 repurchase, and (2) in the case of such rights or warrants that shall have
expired or been terminated without exercise thereof, the Conversion Rate shall
be readjusted as if such expired or terminated rights and warrants had not been
issued.

      For purposes of this Section 5.07(d) and Section 5.07(a) and (b), any
dividend or distribution to which this Section 5.07(d) is applicable that also
includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock described in Section 5.07(b) (or both), shall be
deemed instead to be (1) a dividend or distribution of the evidences of assets,
debt securities or shares of capital stock other than such shares of Common
Stock or rights or warrants (and any Conversion Rate adjustment required by this
Section 5.07(d) with respect to such dividend or distribution shall then be
made) immediately followed by (2) a dividend or distribution of such shares of
Common Stock or such rights or warrants (and any further Conversion Rate
adjustment required by Sections 5.07(a) and 5.07(b) with respect to such
dividend or distribution shall then be made), except (A) the Regular Record Date
of such dividend or distribution shall be substituted as "the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution", "the date fixed for the determination of stockholders entitled to
receive such rights or warrants" and "the date fixed for such determination"
within the meaning of Section 5.07(a) and 5.07(b) and (B) any shares of Common
Stock included in such dividend or distribution shall not be deemed "outstanding


                                       40

at the close of business on the date fixed for such determination" within the
meaning of Section 5.07(a).

      (B) If the Company pays a dividend or makes a distribution to all holders
of its Common Stock consisting of capital stock of any class or series, or
similar equity interests, of or relating to a Subsidiary or other business unit
of the Company, 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
Regular Record Date with respect to such distribution by a fraction,

            (i) the numerator of which shall be the sum of (A) the average of
      the Closing Prices of the Common Stock for the ten (10) Trading Days
      commencing on and including the fifth Trading Day after the date on which
      "EX-DIVIDEND TRADING" commences for such dividend or distribution on The
      New York Stock Exchange or such other national or regional exchange or
      market which such securities are then listed or quoted (the "EX-DIVIDEND
      TIME") plus (B) the fair market value of the securities distributed in
      respect of each share of Common Stock for which this Section applies
      (which shall equal the number of securities distributed in respect of each
      share of Common Stock multiplied by the average of the Closing Prices of
      those securities distributed for the ten (10) Trading Days commencing on
      and including the fifth Trading Day after the Ex-Dividend Time); and

            (ii) the denominator of which shall be the average of the Closing
      Prices of the Common Stock for the ten (10) Trading Days commencing on and
      including the fifth Trading Day after the Ex-Dividend Time,

such adjustment to become effective immediately prior to the opening of business
on the day following fifteenth Trading Day after the Ex-Dividend Time. As used
in this Section 5.07(d)(B), the "Closing Price" for any securities distributed
with respect to the Common Stock shall be determined in the same manner (to the
extent possible) as set forth in the definitions of "Closing Price" except that
references to the term "Common Stock" in such definition shall be replaced with
"the distributed securities referred to in Section 5.07(d)(B)".

      (e) In case the Company shall, by dividend or otherwise, make
distributions consisting exclusively of cash to all holders of its Common Stock,
excluding any dividend in connection with our liquidation, dissolution or
winding up or any cash dividend on the Common Stock to the extent that the
aggregate cash dividend per share of Common Stock in any quarter does not exceed
$0.16 (the "DIVIDEND THRESHOLD AMOUNT") (the Dividend Threshold Amount shall be
subject to adjustment on an inversely proportional basis whenever the Conversion
Rate is adjusted, provided that no adjustment will be made to the Dividend


                                       41

Threshold Amount for any adjustment to the Conversion Rate pursuant to this
clause (e)) then, in each such case, 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 record date by a
fraction,

            (i) the numerator of which shall be the Current Market Price on such
      record date; and

            (ii) the denominator of which shall be the Current Market Price on
      such record date minus the amount of cash so distributed applicable to one
      share of Common Stock,

such adjustment to be effective immediately prior to the opening of business on
the day following the record date; provided that if the portion of the cash so
distributed applicable to one share of Common Stock is equal to or greater than
the Current Market Price on the record date, in lieu of the foregoing
adjustment, adequate provision shall be made so that each Holder shall have the
right to receive upon conversion the amount of cash such holder would have
received had such holder converted each Senior Note on the Regular Record Date.
If 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. If any adjustment is
required to be made as set forth in this Section 5.07(e) as a result of a
distribution that is a quarterly dividend, such adjustment shall be based upon
the amount by which such distribution exceeds the Dividend Threshold Amount. If
an adjustment is required to be made as set forth in this Section 5.07(e) above
as a result of a distribution that is not a quarterly dividend, such adjustment
shall be based upon the full amount of the distribution.

      (f) In case a tender or exchange offer made by the Company or any
Subsidiary for all or any portion of the Common Stock shall expire and such
tender or exchange offer (as amended upon the expiration thereof) shall require
the payment to stockholders of consideration per share of Common Stock having a
Fair Market Value (as determined by the Board of Directors, whose determination
shall be conclusive and described in a resolution of the Board of Directors)
that as of the last time (the "EXPIRATION TIME") tenders or exchanges may be
made pursuant to such tender or exchange offer (as it may be amended) exceeds
the Closing Price of a share of Common Stock on the Trading Day next succeeding
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 Expiration Time by a fraction,

            (i) the numerator of which shall be the sum of (x) the Fair Market
      Value (determined as aforesaid) of the aggregate consideration payable to
      stockholders based on the acceptance (up to any maximum


                                       42

      specified in the terms of the tender or exchange offer) of all shares
      validly tendered or exchanged 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 (y) the product of the number of shares of
      Common Stock outstanding (less any Purchased Shares) at the Expiration
      Time and the Closing Price of a share of Common Stock on the Trading Day
      next succeeding the Expiration Time; and

            (ii) the denominator of which shall be the product of the number of
      shares of Common Stock outstanding (including any Purchased Shares) at the
      Expiration Time and the Closing Price of a share of Common Stock on the
      Trading Day next succeeding the Expiration Time.

      (g) In case of a tender or exchange offer made by a Person other than the
Company or any Subsidiary for an amount that increases the offeror's ownership
of Common Stock to more than twenty-five percent (25%) of the Common Stock
outstanding and shall involve the payment by such Person of consideration per
share of Common Stock having a Fair Market Value (as determined by the Board of
Directors, whose determination shall be conclusive, and described in a
resolution of the Board of Directors) as of the Expiration Time tenders or
exchanges may be made pursuant to such tender or exchange offer (as it may be
amended) that exceeds the Current Market Price per share of Common Stock on the
Trading Day next succeeding the Expiration Time, and in which, as of the
Expiration Time the Board of Directors is not recommending rejection of the
offer, the Conversion Price shall be increased so that the same shall equal the
rate determined by multiplying the Conversion Rate in effect immediately prior
to the Expiration Time by a fraction,

            (i) the numerator of which shall be the sum of (x) the Fair Market
      Value (determined as aforesaid) of the aggregate consideration payable to
      stockholders based on the acceptance (up to any maximum specified in the
      terms of the tender or exchange offer) of all shares validly tendered or
      exchanged and not withdrawn as of the Expiration Time and (y) the product
      of the number of shares of Common Stock outstanding (less any Purchased
      Shares) at the Expiration Time and the Closing Price of a share of Common
      Stock on the Trading Day next succeeding the Expiration Time; and

            (ii) the denominator of which shall be the number of shares of
      Common Stock outstanding (including any Purchased Shares) at the
      Expiration Time multiplied by the Closing Price of a share of Common Stock
      on the Trading Day next succeeding the Expiration Time,

such adjustment to become effective immediately prior to the opening of business
on the day following the Expiration Time. If such Person is obligated to
purchase


                                       43

shares pursuant to any such tender or exchange offer, but such Person is
permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the Conversion Price shall again be adjusted to be
the Conversion Price that would then be in effect if such tender or exchange
offer had not been made. Notwithstanding the foregoing, the adjustment described
in this Section 5.07(g) shall not be made if, as of the Expiration Time, the
offering documents with respect to such offer disclose a plan or intention to
cause the Company to engage in any transaction described in Article 5.

      (h) In any case in which this Section 5.07 shall require that an
adjustment be made immediately following a record date established for purposes
of Section 5.07, 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 5.07) issuing to the holder of any Senior Note converted
after such record 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 issuable upon such conversion only on the
basis of the Conversion Price prior to adjustment; and, in lieu of the shares
the issuance of which is so deferred, the Company shall issue or cause its
transfer agents to issue due bills or other appropriate evidence of the right to
receive such shares. In the event of Sections 5.07(e) or 5.07(f), in no event
will the Conversion Rate exceed 25.0250 shares of Common Stock per $1,000
principal amount of the Senior Notes, subject to adjustment from Sections
5.07(a) through 5.07(d) and 5.07(g). For purposes of this Section 5.07, the
following terms shall have the meaning indicated:

            (i) CURRENT MARKET PRICE" of the Common Stock on any day means the
      average of the Closing Prices per share of the Common Stock for each of
      the ten (10) consecutive Trading Days ending on the earlier of the day in
      question and the day before the "Ex-Dividend Date" with respect to the
      issuance or distribution requiring such computation.

If another issuance, distribution, subdivision or combination to which Section
5.07 applies occurs during the period applicable for calculating "CURRENT MARKET
PRICE" pursuant to the definition in the preceding paragraph, "CURRENT MARKET
PRICE" shall be calculated for such period in a manner determined by the Board
of Directors to reflect the impact of such issuance, distribution, subdivision
or combination on the Closing Price of the Common Stock during such period.

            (ii) "FAIR MARKET VALUE" shall mean the amount which a willing buyer
      would pay a willing seller in an arm's-length transaction.

            (iii) "REGULAR 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


                                       44

      property or in which the Common Stock (or other applicable security) is
      exchanged for or converted into any combination of cash, securities or
      other property, the date fixed for determination of stockholders entitled
      to receive such cash, securities or other property (whether such date is
      fixed by the Board of Directors or by statute, contract or otherwise).

      (i) The Company may make such increases in the Conversion Rate in addition
to those required by Section 5.07(a), (b), (c), (d), (e), (f) or (g) as the
Board of Directors considers to be advisable to avoid or diminish any income tax
to holders of Common Stock or rights to purchase Common Stock resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event
treated as such for income tax purposes.

      To the extent permitted by applicable law, the Company from time to time
may increase the Conversion Rate by any amount for any period of time if the
period is at least twenty (20) days, the increase is irrevocable during the
period and the Board of Directors shall have made a determination that such
increase would be in the best interests of the Company, which determination
shall be conclusive. Whenever the Conversion Rate is increased pursuant to the
preceding sentence, the Company shall mail to Holders a notice of the increase
at least fifteen (15) days prior to the date the increased Conversion Rate takes
effect, and such notice shall state the increased Conversion Rate and the period
during which it will be in effect.

      (j) No adjustment in the Conversion Rate shall be required unless such
adjustment would require an increase or decrease of at least one percent (1%) in
such rate; provided that any adjustments that by reason of this Section 5.07(j)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Article 5 shall be made
by the Company and shall be made to the nearest cent or to the nearest one-ten
thousandth (1/10,000) of a share, as the case may be. To the extent the Senior
Notes become convertible into cash, assets or property, subject to Section 5.10,
no adjustment need be made thereafter as to the cash, assets or property.
Interest will not accrue on any cash into which the Senior Notes are
convertible.

      (k) Whenever the Conversion Rate is adjusted as herein provided, the
Company shall promptly file with the Trustee and any Conversion Agent other than
the Trustee an Officers' Certificate setting forth the Conversion Rate after
such adjustment and setting forth a brief statement of the facts requiring such
adjustment. Unless and until a Trust Officer of the Trustee or an Officer of the
Conversion Agent shall have received such Officers' Certificate, the Trustee or
Conversion Agent, as the case may be, shall not be deemed to have knowledge of
any adjustment of the Conversion Rate and may assume that the last Conversion
Rate of which it has knowledge is still in effect. Promptly after delivery of
such certificate, the Company shall disseminate a press release through Dow
Jones &


                                       45

Company, Inc. or Bloomberg Business News and publish such information on the
Company's Web site setting forth the adjusted Conversion Rate, the date on which
each adjustment becomes effective, and a brief statement of the facts requiring
such adjustment.

      (l) In any case in which this Section 5.07 provides that an adjustment
shall become effective immediately after (1) a record date or Regular Record
Date for an event, (2) the date fixed for the determination of stockholders
entitled to receive a dividend or distribution pursuant to Section 5.07(a), (3)
a date fixed for the determination of stockholders entitled to receive rights or
warrants pursuant to Section 5.07(b), or (4) the Expiration Time for any tender
or exchange offer pursuant to Section 5.07(f) (each a "DETERMINATION DATE"), the
Company may elect to defer until the occurrence of the applicable Adjustment
Event (as hereinafter defined) (x) issuing to the holder of any Senior Note
converted after such Determination Date and before the occurrence of such
Adjustment Event, the additional shares of Common Stock or other securities
issuable upon such conversion, or cash in lieu thereof, by reason of the
adjustment required by such Adjustment Event over and above the Common Stock
issuable upon such conversion, or cash in lieu thereof, before giving effect to
such adjustment and (y) paying to such holder any amount in cash in lieu of any
fraction pursuant to Section 5.04. For purposes of this Section 5.07(l), the
term "ADJUSTMENT EVENT" shall mean:

            (i) in any case referred to in clause (1) hereof, the occurrence of
      such event,

            (ii) in any case referred to in clause (2) hereof, the date any such
      dividend or distribution is paid or made,

            (iii) in any case referred to in clause (3) hereof, the date of
      expiration of such rights or warrants, and

            (iv) in any case referred to in clause (4) hereof, the date a sale
      or exchange of Common Stock pursuant to such tender or exchange offer is
      consummated and becomes irrevocable.

      (m) For purposes of this Section 5.07, the number of shares of Common
Stock at any time outstanding shall not include shares held in the treasury of
the Company, unless such treasury shares participate in any distribution or
dividend that requires an adjustment pursuant to this Section 5.07, but shall
include shares issuable in respect of scrip certificates issued in lieu of
fractions of shares of Common Stock.

      Section 5.08. When No Adjustment Required. No adjustment to the Conversion
Rate need be made:


                                       46

      (a) upon the issuance of any shares of Common Stock pursuant to any
present or future plan providing for the reinvestment of dividends or interest
payable on securities of the Company and the investment of additional optional
amounts in shares of Common Stock under any plan;

      (b) upon the issuance of any shares of Common Stock or options or rights
to purchase or acquire those shares pursuant to any present or future employee,
director or consultant benefit plan or program of or assumed by the Company or
any of its Subsidiaries;

      (c) upon the issuance of any shares of Common Stock pursuant to any
option, warrant, right, or exercisable, exchangeable or convertible security not
described in paragraph (b) above and outstanding as of the date of this
Supplemental Indenture;

      (d) for a change in the par value or no par value of the Common Stock; or

      (e) for accrued and unpaid interest.

      Section 5.09. Notice of Certain Transactions. In the event that:

            (i) the Company takes any action that requires a supplemental
      indenture pursuant to Section 5.10; or

            (ii) 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 or effective date, as the case may be. The Company shall mail
the notice at least fifteen days before such date. Failure to mail such notice
or any defect therein shall not affect the legality or validity of any
transaction referred to in clause (i) or (ii) of this Section 5.09.

      Section 5.10. Effect of Reclassification, Consolidation, Merger or Sale on
Conversion Privilege. If any of the following events occur, namely (i) any
reclassification or change of the outstanding shares of Common Stock (other than
a subdivision or combination to which Section 5.07(c) applies), (ii) any
consolidation, merger, binding share exchange or combination of the Company with
another Person as a result of which holders of Common Stock shall be entitled to
receive stock, other securities or other property or assets (including cash)
with respect to or in exchange for such Common Stock, or (iii) any sale or
transfer of all or substantially all of the properties and assets of the Company
to any other Person as a result of which holders of Common Stock shall be
entitled to receive stock, other securities or other property or assets
(including cash) with respect to or in exchange for such Common Stock, then the
Company or the


                                       47

successor or purchasing Person, as the case may be, shall execute with the
Trustee a supplemental indenture (which shall comply with the Trust Indenture
Act as in force at the date of execution of such supplemental indenture)
providing that each Senior Note shall be convertible into the kind and amount of
shares of stock, other securities or other property or assets (including cash)
receivable upon such reclassification, change, consolidation, merger, binding
share exchange, combination, sale or transfer by a holder of a number of shares
of Common Stock issuable upon conversion of such Senior Notes (assuming, for
such purposes, a sufficient number of authorized shares of Common Stock are
available to convert all such Senior Notes) immediately prior to such
reclassification, change, consolidation, merger, combination, binding share
exchange, sale or transfer assuming such holder of Common Stock did not exercise
his rights of election, if any, as to the kind or amount of stock, other
securities or other property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, binding share exchange,
combination, sale or transfer (provided that, if the kind or amount of stock,
other securities or other property or assets (including cash) receivable upon
such reclassification, change, consolidation, merger, combination, sale or
transfer is not the same for each share of Common Stock in respect of which such
rights of election shall not have been exercised ("NON-ELECTING SHARE"), then
for the purposes of this Section 5.10 the kind and amount of stock, other
securities or other property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, binding share exchange,
combination, sale or transfer for each non-electing share shall be deemed to be
the kind and amount so receivable per share by a plurality of the non-electing
shares). Such supplemental indenture shall provide for adjustments which shall
be as nearly equivalent as may be practicable to the adjustments provided for in
this Article 5.

      The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each Holder of Senior Notes, at its address appearing
on the Security Register, within twenty (20) days after execution thereof and
shall issue a press release containing such information and publish such
information on its website on the World Wide Web. Failure to deliver such notice
shall not affect the legality or validity of such supplemental indenture.

      The above provisions of this Section 5.10 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, binding share
exchanges, combinations, sales and transfers.

      If this Section 5.10 applies to any event or occurrence, Section 5.07
shall not apply.

      Section 5.11. Trustee's Disclaimer. The Trustee shall have no duty to
determine when an adjustment under this Article 5 should be made, how it should
be made or what such adjustment should be, but may accept as conclusive


                                       48

evidence of that fact or the correctness of any such adjustment, and shall be
protected in relying upon, an Officers' Certificate including the Officers'
Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 5.07(k). The Trustee makes no representation as to
the validity or value of any securities or assets issued upon conversion of
Senior Notes, and the Trustee shall not be responsible for the Company's failure
to comply with any provisions of this Article 5.

      The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 5.10, but may accept as conclusive evidence of the
correctness thereof, and shall be fully protected in relying upon, the Officers'
Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 5.07(k).

      Section 5.12. Rights Issued in Respect of Common Stock Issued upon
Conversion. Each share of Common Stock issued upon conversion of Senior Notes
pursuant to this Article 5 shall be entitled to receive the appropriate number
of common stock or preferred stock purchase rights, as the case may be (the
"RIGHTS"), if any, that shares of Common Stock are entitled to receive and the
certificates representing the Common Stock issued upon such conversion shall
bear such legends, if any, in each case as may be provided by the terms of any
shareholder rights agreement adopted by the Company, as the same may be amended
from time to time (in each case, a "RIGHTS Agreement"). Provided that such
Rights Agreement requires that each share of Common Stock issued upon conversion
of Senior Notes at any time prior to the distribution of separate certificates
representing the Rights be entitled to receive such Rights, then,
notwithstanding anything else to the contrary in this Article 5, there shall not
be any adjustment to the conversion privilege or Conversion Rate as a result of
the issuance of Rights, but an adjustment to the Conversion Rate shall be made
pursuant to Section 5.07(d) upon the separation of the Rights from the Common
Stock. The Conversion Rate shall be readjusted in the event of the expiration,
termination or redemption of the Rights prior to conversion of Senior Notes.

      Section 5.13. Company Determination Final. Any determination that the
Company or the Board of Directors must make pursuant to Article 5 shall be
conclusive, absent mathematical error.

      Section 5.14. Conversion Provisions in Base Indenture. The provisions in
this Article 5 shall supersede and replace in their entirety the provisions set
forth in Sections 14.02 through and including 14.11 of the Base Indenture.

                                   Amendments

      Section 6.01. Without Consent of Holders. The Company and the Trustee may
amend the Indenture or the Senior Notes without the consent of any
Securityholder to:

            (a) add to the covenants of the Company for the benefit of the
      Holders of Senior Notes;

            (b) surrender any right or power herein conferred upon the Company;

            (c) provide for conversion rights of Holders of Senior Notes if any
      reclassification or change of the Common Stock or any consolidation,
      merger or sale of all or substantially all of the Company's assets occurs;
      (d) provide for the assumption of the Company's obligations to the Holders
      of Senior Notes in the case of a merger, consolidation, conveyance,
      transfer or lease or the release of the predecessor;

            (d) provide for the assumption of the Company's obligations to the
      Holders of Senior Notes in the case of a merger, consolidation,
      conveyance, transfer or lease or the release of the predecessor;

            (e) increase the Conversion Rate; provided, however, that such
      increase in the Conversion Rate shall not adversely affect the interests
      of the Holders of Senior Notes (after taking into account tax and other
      consequences of such increase);

            (f) comply with the requirements of the SEC in order to effect or
      maintain the qualification of the Indenture under the TIA; and

            (g) cure any ambiguity, to correct or supplement any provision
      herein which may be inconsistent with any other provision herein or which
      is otherwise defective, or to make, add or modify any other provisions
      with respect to matters or questions arising under the Indenture which the
      Company may deem necessary or desirable and which shall not be
      inconsistent with the provisions of the Indenture; provided, however, that
      such action pursuant to this clause (g) does not, in the good faith
      opinion of the Board of Directors of the Company (as evidenced by a Board
      Resolution) and the Trustee, adversely affect the interests of the Holders
      of Senior Notes in any material respect.

      Section 6.02. With Consent of Holders. Except as provided below in this
Section 6.02, the Indenture or the Senior Notes may be amended, modified or
supplemented, and noncompliance in any particular instance with any provision of
the Indenture or the Senior Notes may be waived, in each case with the written


                                       50

consent of the Holders of at least a majority of the principal amount of the
Senior Notes at the time outstanding.

      Without the written consent or the affirmative vote of each Holder of
Senior Notes affected thereby, an amendment, supplement or waiver under this
Section 6.02 may not:

            (a) change the maturity of any Senior Note, or the payment date of
      any installment of Interest payable on any Senior Note;

            (b) reduce the principal amount of, or the Interest, payable on, or
      the Redemption Price, Purchase Price or Fundamental Change Purchase Price
      of, any Senior Note;

            (c) change the currency of any amount owed or owing under the Senior
      Notes or any Interest thereon from U.S. Dollars;

            (d) alter or otherwise modify the rate of Interest on any Senior
      Note, or the manner of calculation thereof, or extend time for payment of
      any amounts due and payable to the Holders of the Senior Notes;

            (e) impair the right of any Holder to institute suit for the
      enforcement of any payment or with respect to, or conversion of, any
      Senior Note;

            (f) modify the Company's obligation to maintain an office or agency
      in New York City;

            (g) adversely affect the purchase right of the Holders of the Senior
      Notes as provided in Article 3 or the right of the Holders of the Senior
      Notes to convert any Senior Note as provided in Article 5, except as
      otherwise permitted by the Indenture;

            (h) modify the redemption provisions of Article 3 in a manner
      adverse to the Holders of the Senior Notes;

            (i) modify any of the provisions of this Section, or reduce the
      percentage of the aggregate principal amount of outstanding Senior Notes
      required to amend, modify or supplement the Indenture or the Senior Notes
      or waive an Event of Default, except to provide that certain other
      provisions of the Indenture cannot be modified or waived without the
      consent of the Holder of each outstanding Senior Note affected thereby; or

            (j) reduce the percentage of the aggregate principal amount of the
      outstanding Senior Notes the consent of whose Holders is required for any
      such supplemental indenture entered into in accordance with this


                                       51

      Section 6.02 or the consent of whose Holders is required for any waiver
      provided for in the Indenture.

      It shall not be necessary for the consent of the Holders under this
Section 6.02 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof.

      After an amendment under this Section 6.02 becomes effective, the Company
shall mail to each Holder a notice briefly describing the amendment.

      Nothing in this Section 6.02 shall impair the ability of the Company and
the Trustee to amend the Indenture or the Senior Notes without the consent of
any Holder to provide for the assumption of the Company's obligations to the
Holders of Senior Notes in the case of a merger, consolidation, conveyance,
transfer or lease pursuant to Article 8 of the Base Indenture.

      Section 6.03. Execution and Effect of Amendments. (a) In executing, or
accepting the additional trusts created by, any amendment or supplement
permitted by this Article or the modifications thereby of the trusts created by
the Indenture, the Trustee shall be entitled to receive, and (subject to Section
6.01 of the Base Indenture) shall be fully protected in relying upon, an Opinion
of Counsel stating that the execution of such amendment or supplemental
indenture is authorized or permitted by this Indenture. The Trustee may, but
shall not be obligated to, enter into any such amendment or supplemental
indenture, as the case may be, which affects the Trustee's own rights, duties or
immunities under the Indenture or otherwise.

      (b) Upon the execution of any amendment or supplemental indenture under
this Article, the Indenture shall be modified in accordance therewith, and such
amendment or supplemental indenture, as the case may be, shall form a part of
the Indenture for all purposes; and every Holder of Senior Notes theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby.

      (c) Every amendment or supplemental indenture executed pursuant to this
Article shall conform to the requirements of the TIA.

      (d) Senior Notes authenticated and delivered after the execution of any
amendment or supplemental indenture pursuant to this Article may, and shall if
required by the Trustee, bear a notation in form approved by the Trustee as to
any matter provided for in such amendment or supplemental indenture. If the
Company shall so determine, new Senior Notes so modified as to conform, in the
opinion of the Trustee and the Company, to any such amendment or supplemental
indenture may be prepared and executed by the Company and authenticated and
delivered by the Trustee in exchange for Outstanding Senior Notes.

contained in this Supplemental Indenture or in the Senior Notes shall for any
reason be held to be invalid, illegal or unenforceable in any respect, then, to

shall not affect any other provisions of this Supplemental Indenture or of the
Senior Notes, but this Supplemental Indenture and the Senior Notes shall be
construed as if such invalid or illegal or unenforceable provision had never
been contained herein or therein.

      Section 7.05. Counterparts. This Supplemental Indenture may be executed in
any number of counterparts each of which shall be an original, but such
counterparts shall together constitute but one and the same instrument.

together with the Base Indenture, the "INDENTURE") and reference is hereby made
to the Indenture and all indentures supplemental thereto for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Senior Notes and of the terms
upon which the Senior Notes are, and are to be, authenticated and delivered.
This Senior Note is one of the series designated on the face hereof.

1.    INTEREST.

      The Senior Notes shall bear interest on the principal amount thereof at a
rate of 1.50% per annum (the "INTEREST").

      Except as otherwise provided below or in the Indenture, Interest will be
payable semi-annually on each Interest Payment Date to Holders at the close of
business on the preceding Record Date. Interest will be computed on the basis of
a 360-day year comprised of twelve 30-day months.

      The Company will pay Interest to a person other than the Holder of record
on the Record Date if the Company elects to redeem the Senior Notes on a date
that is after a Record Date but prior to the corresponding Interest Payment
Date. In that instance, the Company will pay accrued and unpaid Interest, if
any, on the Senior Notes being redeemed to, but not including, the Redemption
Date to the same person to whom it will pay the principal of those Senior Notes.

2.    METHOD OF PAYMENT.

      The Company shall pay Interest on this Global Senior Notes to DTC in
immediately available funds.

      Subject to the terms and conditions of the Indenture, the Company will
make payments in cash or, in certain cases specified in the Indenture, in cash,
shares of Common Stock or a combination thereof, as the case may be, in respect
of Redemption Prices, Purchase Prices, Fundamental Change Purchase Prices and at
Stated Maturity to Holders who surrender Senior Notes to a Paying Agent to
collect such payments in respect of the Senior Notes. The Company will pay cash
amounts in money of the United States that at the time of payment is legal
tender for payment of public and private debts.


                                       A-5


3.    [RESERVED]

4.    INDENTURE.

      The Senior Notes are general unsecured obligations of the Company limited
to $300,000,000 aggregate principal amount (up to $330,000,000 aggregate
principal amount if the Underwriters' option set forth in the Underwriting
Agreement is exercised in full). The Indenture does not limit other indebtedness
of the Company, secured or unsecured.

5.    REDEMPTION AT THE OPTION OF THE COMPANY.

      No sinking fund is provided for the Senior Notes. Subject to the terms and
conditions of the Indenture, the Senior Notes are redeemable for cash at the
option of the Company, in whole or in part, at any time or from time to time on
or after February 16, 2009 upon not less than 30 nor more than 60 days' notice
by mail to each Holder of Senior Notes to be redeemed at the Holder's registered
address, for a redemption price equal to the principal amount of the Senior
Notes called for redemption plus accrued and unpaid Interest, if any, on those
Senior Notes up to (but excluding) the Redemption Date (the "REDEMPTION PRICE").
At the Company's request, the Trustee shall give the notice of redemption in the
Company's name and at the Company's expense, provided that the Company makes
such request at least seven Business Days (or such shorter period as may be
satisfactory to the Trustee) prior to the date by which such notice of
redemption must be given to Holders in accordance with the Indenture. If money
sufficient to pay the Redemption Price of all Senior Notes (or portions thereof)
to be redeemed on the Redemption Date is deposited with the Paying Agent prior
to 10:00 a.m., New York City time, on the Redemption Date, immediately on and
after such Redemption Date, Interest, if any, will cease to accrue on such
Senior Notes or portions thereof. Senior Notes in denominations larger than
$1,000 principal amount may be redeemed in part but only in integral multiples
of $1,000 of principal amount.

      In no event will any Senior Note be redeemable before February 16, 2009.

6.    PURCHASE BY THE COMPANY AT THE OPTION OF THE HOLDER.

      Subject to the terms and conditions of the Indenture, the Company shall
become obligated to purchase, at the option of the Holder, all or any portion of
the Senior Notes held by such Holder on February 15, 2009, February 15, 2014 and
February 15, 2019 in integral multiples of $1,000 at a Purchase Price equal to
the principal amount of those Senior Notes plus accrued and unpaid Interest, if
any, on those Senior Notes up to (but excluding) the Purchase Date. To exercise
such right, a Holder shall deliver to the Paying Agent a Purchase Notice
containing the information set forth in the Indenture, at any time from the
opening of business on the date that is 22 Business Days prior to such Purchase
Date until the close of


                                       A-6


business on the Business Day prior to such Purchase Date, and shall deliver the
Senior Notes to the Paying Agent as set forth in the Indenture.

      The Company shall pay the Purchase Price on February 15, 2009 in cash and
the Purchase Price on February 15, 2014 and February 15, 2019 in cash or shares
of Common Stock (or any combination thereof), at the Company's option, subject
to the terms and conditions of the Indenture. At any time prior to Stated
Maturity, the Company may irrevocable elect in its sole discretion to satisfy
100% of the principal amount of the Senior Note offered to be purchased after
the date of such election (plus accrued and unpaid interest) in cash.

      Subject to the terms and conditions of the Indenture, the Company shall
become obligated to offer to purchase the Senior Notes held by such Holder
within 15 days (which purchase shall occur, at the option of the Holder, no
later than 25 Business Days after the date of such offer) after the occurrence
of a Fundamental Change of the Company for a Fundamental Change Purchase Price
equal to the principal amount of those Senior Notes plus accrued and unpaid
Interest, if any, on those Senior Notes up to (but excluding) the Fundamental
Change Purchase Date; provided that, if the Fundamental Change Purchase Date is
after a Record Date and before the next succeeding Interest Payment Date,
accrued and unpaid Interest, if any, on those Senior Notes shall be paid to the
Holder as of that Record Date. The Fundamental Change Purchase Price will be
paid in cash, subject to the terms and conditions of the Indenture.

      Holders have the right to withdraw any Purchase Notice or Fundamental
Change Purchase Notice, as the case may be, by delivering to the Paying Agent a
written notice of withdrawal in accordance with the provisions of the Indenture.

      If cash (and/or Common Stock if permitted under the Indenture) sufficient
to pay the Purchase Price or Fundamental Change Purchase Price, as the case may
be, of all Senior Notes or portions thereof to be purchased as of the Purchase
Date or the Fundamental Change Purchase Date, as the case may be, is deposited
with the Paying Agent prior to 10:00 a.m., New York City time, on the Purchase
Date or the Fundamental Change Purchase Date, Interest, if any, will cease to
accrue on such Senior Notes (or portions thereof) immediately after such
Purchase Date or Fundamental Change Purchase Date, and the Holder thereof shall
have no other rights as such other than the right to receive the Purchase Price
or Fundamental Change Purchase Price upon surrender of such Senior Note.

7.    [RESERVED]

8.    CONVERSION.

      Subject to and in compliance with the provisions of the Indenture
(including, without limitation, the conditions to conversion of this Senior Note
set forth in Section 5.01 of the Supplemental Indenture), a Holder is entitled,
at such Holder's option, to convert the Holder's Senior Note (or any portion of
the


                                       A-7


principal amount thereof that is $1,000 or an integral multiple $1,000), into
fully paid and nonassessable shares of Common Stock at the Conversion Price in
effect at the time of conversion. Upon conversion, in lieu of Common Stock, the
Company will have the right, subject to certain rights of retraction by the
Holder set forth in the Indenture, to deliver cash or a combination of cash and
shares of Common Stock. At any time prior to Stated Maturity, the Company may
irrevocable elect in its sole discretion to satisfy up to 100% of the principal
amount of the Senior Note surrendered after the date of such election (plus
accrued and unpaid Interest) in cash, with any remaining amount to be satisfied
in shares of Common Stock.

      Upon determination that Holders are or will be entitled to convert the
Senior Notes, the Company shall disseminate a press release through Dow Jones &
Company, Inc. or Bloomberg Business News and publish such information on the
Company's Web site as soon as practicable.

      A Senior Note in respect of which a Holder has delivered a Purchase Notice
or Fundamental Change Purchase Notice, as the case may be, exercising the option
of such Holder to require the Company to purchase such Senior Note may be
converted only if such Purchase Notice or Fundamental Change Purchase Notice, as
the case may be, is withdrawn in accordance with the terms of the Indenture.

      The initial Conversion Rate is 17.8750 shares of Common Stock per $1,000
principal amount of Senior Notes, subject to adjustment upon certain events
described in the Indenture. The Conversion Rate shall not be adjusted for any
accrued and unpaid Interest. Upon conversion, no payment shall be made by the
Company with respect to accrued and unpaid Interest, if any. Instead, such
amount shall be deemed paid by the shares of Common Stock or the cash amount as
determined pursuant to the Indenture, or any combination thereof, delivered upon
conversion of any Senior Note. In addition, no payment or adjustment shall be
made in respect of dividends on the Common Stock, except as set forth in the
Indenture.

      To surrender a Senior Note for conversion, a Holder must (1) complete and
manually sign the Notice of Conversion attached hereto (or complete and manually
sign a facsimile of such notice) and deliver such notice to the Conversion
Agent, (2) surrender the Senior Note to the Conversion Agent, (3) furnish
appropriate endorsements and transfer documents if required by the Security
Registrar or the Conversion Agent, (4) pay any transfer or similar tax, if
required and (5) if required pay funds equal to the Interest payable on the next
Interest Payment Date.

      No fractional shares of Common Stock shall be issued upon conversion of
any Senior Note. Instead of any fractional share of Common Stock that would


                                       A-8


otherwise be issued upon conversion of such Senior Note, the Company shall pay a
cash adjustment as provided in the Indenture.

      If the Company (i) is a party to a consolidation, merger or binding share
exchange, (ii) reclassifies the Common Stock, or (iii) transfers all or
substantially all of its assets to any Person, the right to convert a Senior
Note into shares of Common Stock may be changed into a right to convert it into
the securities, cash or other assets of the Company or such other Person, in
each case in accordance with the Indenture.

9.    [RESERVED]

10.   PAYING AGENT, CONVERSION AGENT, REGISTRAR AND CALCULATION AGENT.

      Initially, the Trustee will act as Paying Agent, Conversion Agent,
Security Registrar and Calculation Agent. The Company may appoint and change any
Paying Agent, Conversion Agent, Security Registrar or Calculation Agent without
notice, other than notice to the Trustee; provided that the Company will
maintain at least one Paying Agent in the State of New York, City of New York,
Borough of Manhattan, which shall initially be an office or agency of the
Trustee. The Company or any of its Subsidiaries or any of their Affiliates may
act as Paying Agent, Conversion Agent, Security Registrar or Calculation Agent.

11.   DENOMINATIONS; TRANSFER; EXCHANGE.

      The Senior Notes are in fully registered form, without coupons, in
denominations of $1,000 of principal amount and integral multiples of $1,000. A
Holder may transfer or exchange Senior Notes in accordance with the Indenture.
The Security Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay any taxes and fees
required by law or permitted by the Indenture. The Security Registrar need not
transfer or exchange any Senior Notes selected for redemption (except, in the
case of a Senior Note to be redeemed in part, the portion of the Senior Note not
to be redeemed) or any Senior Notes in respect of which a Purchase Notice or
Change of Control Purchase Notice has been given and not withdrawn (except, in
the case of a Senior Note to be purchased in part, the portion of the Senior
Note not to be purchased) or any Senior Notes for a period of 15 days before the
mailing of a notice of redemption of Senior Notes to be redeemed.

12.   PERSONS DEEMED OWNERS.

      The registered Holder of this Senior Note may be treated as the owner of
this Senior Note for all purposes.


                                       A-9


13.   UNCLAIMED MONEY OR SENIOR NOTES.

      The Trustee and the Paying Agent shall return to the Company upon written
request any money or securities held by them for the payment of any amount with
respect to the Senior Notes that remains unclaimed for two years, subject to
applicable unclaimed property law. After return to the Company, Holders entitled
to the money or securities must look to the Company for payment as general
creditors unless an applicable abandoned property law designates another person.

14.   AMENDMENT; WAIVER.

      Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Senior Notes may be amended with the written consent of the
Holders of at least a majority in aggregate principal amount of the outstanding
Senior Notes and (ii) certain Events of Defaults may be waived with the written
consent of the Holders of a majority in aggregate principal amount of the
outstanding Senior Notes. Subject to certain exceptions set forth in the
Indenture, without the consent of any Holder, the Company and the Trustee may
amend the Indenture or the Senior Notes (i) to add to the covenants of the
Company for the benefit of the Holders of Senior Notes, (ii) to surrender any
right or power conferred upon the Company in the Indenture, (iii) to provide for
conversion rights of Holders of Senior Notes in the case of any reclassification
or change of the Company's Common Stock or any consolidation, merger or sale of
all or substantially all of the Company's assets, (iv) to provide for the
assumption of the Company's obligations to the Holders of Senior Notes in the
case of a merger, consolidation, conveyance, transfer or lease pursuant to
Article 8 of the Base Indenture and the release of the predecessor, (v) to
increase the Conversion Rate; provided, however, that such increase in the
Conversion Rate shall not adversely affect the interest of the Holders of Senior
Notes (after taking into account tax and other consequences of such increase),
(vi) to comply with the requirements of the SEC in order to effect or maintain
the qualification of the Indenture under the TIA, and (vii) to cure any
ambiguity, to correct or supplement any provision in the Indenture which may be
inconsistent with any other provision therein or which is otherwise defective,
or to make, add or modify any other provisions with respect to matters or
questions arising under the Indenture which the Company may deem necessary or
desirable and which shall not be inconsistent with the provisions of the
Indenture; provided, however, that such action pursuant to this clause (vii)
does not, in the good faith opinion of the Board of Directors of the Company (as
evidenced by a Board Resolution) and the Trustee, adversely affect the interests
of the Holders of Senior Notes in any material respect.

15.   DEFAULTS AND REMEDIES.

      If any Event of Default with respect to Senior Notes shall occur and be
continuing, the principal amount of the Senior Notes and any accrued and unpaid


                                      A-10


Interest, if any, on all the Senior Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

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

16.   TRUSTEE DEALINGS WITH THE COMPANY.

      Subject to certain limitations imposed by the TIA, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Senior Notes and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

17.   CALCULATIONS IN RESPECT OF SENIOR NOTES.

      The Company or its agents will be responsible for making all calculations
called for under the Senior Notes including, but not limited to, determination
of the market prices for the Senior Notes and the Common Stock. Any calculations
made in good faith, absent mathematical error, will be final and binding on
Holders of the Senior Notes. The Company or its agents will be required to
deliver to the Trustee a schedule of its calculations and the Trustee will be
entitled to conclusively rely upon the accuracy of such calculations without
independent verification.

employee, as such, of the Company, or of any successor corporation or any
Affiliate of the Company, shall have any liability for any obligations of the
Company under the Senior Notes or the Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation, all such
liability


                                      A-11

      FLUOR CORPORATION, a corporation duly organized and existing under the
laws of Delaware (herein called the "COMPANY," which term includes any successor
Person under the Indenture hereinafter referred to), for value received, hereby
promises to pay to ______________, or registered assigns, the principal sum of
______________ on February 15, 2024 and to pay Interest thereon from February
17, 2004 or from the most recent Interest Payment Date to which Interest has
been paid or duly provided for, semi-annually on February 15 and August 15 in
each year, commencing August 15, 2004, at the rate of 1.50% per annum, until the
principal hereof is paid or made available for payment. The Interest so payable,
and punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture and except as otherwise provided therein, be paid to
the Person in whose name this Senior Note (or one or more Predecessor Senior
Notes) is registered at the close of business on the Record Date for such
interest, which shall be February 1 or August 1 (whether or not a Business Day),
as the case may be, next preceding such Interest Payment Date. Any such Interest
not so punctually paid or duly provided for ("Defaulted Interest") will
forthwith cease to be payable to the Holder on such Record Date and may either
be paid to the Person in whose name this Senior Note (or one or more Predecessor
Senior Notes) is registered at the close of business on a Special Record Date
for the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Senior Notes not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Senior Notes may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in said Indenture.

      Reference is hereby made to the further provisions of this Senior Note set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

      Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Senior Note
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.
