                           REDEMPTION AND PURCHASES

     SECTION 1101.  Company's Right to Redeem; Notices to Trustee.

          The Company, at its option, may redeem the Securities in accordance
     with the provisions of Paragraph 5 of the Securities. If the Company elects
     to redeem Securities pursuant to Paragraph 5 of the Securities, it shall

          The Company shall give the notice to the Trustee provided for in this

     (unless a shorter notice shall be satisfactory to the Trustee).

<PAGE>

     SECTION 1102.  Selection of Securities to Be Redeemed.

          If less than all the Securities are to be redeemed, unless the
     procedures of the Depositary provide otherwise, the Trustee shall select
     the Securities to be redeemed by lot, on a pro rata basis or by another
     method the Trustee considers fair and appropriate (so long as such method
     is not prohibited by the rules of any stock exchange on which the
     Securities are then listed).  The Trustee shall make the selection at least
     15 days but not more than 60 days before the Redemption Date from
     outstanding Securities not previously called for redemption. The Trustee
     may select for redemption portions of the principal amount at maturity of
     Securities that have denominations larger than $1,000.

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

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

     SECTION 1103.  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 Securities to be redeemed.

          The notice shall identify the Securities 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 Securities called for redemption may be converted at any
               time before the close of business one Business Day prior to the
               Redemption Date;

          (6)  that Holders who want to convert their Securities must satisfy
               the requirements set forth in Paragraph 7 of the Securities;

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

                                       7
<PAGE>

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

          (9)  that, unless the Company defaults in making payment of such
               Redemption Price, cash interest, if any, on Securities called for
               redemption will cease to accrue and the Securities will not
               accrete in value on and after the Redemption Date; and

          (10) the CUSIP number(s) of the Securities.

          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 three Business Days prior to
     the date by which such notice of redemption must be given to Holders in
     accordance with this Section 1103.

     SECTION 1104.  Effect of Notice of Redemption.

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

     SECTION 1105.  Deposit of Redemption Price.

          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 as provided in Section 606) money sufficient to
     pay the Redemption Price of all Securities to be redeemed on that date
     other than Securities or portions of Securities 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 Securities pursuant to Article Fourteen.  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.

     SECTION 1106.  Securities Redeemed in Part.

          Upon surrender of a Security that is redeemed in part, the Company
     shall execute and the Trustee shall authenticate and deliver to the Holder
     a new Security in an authorized denomination equal in principal amount to
     the unredeemed portion of the Security surrendered.

     purchase price equal to the Accreted Principal Amount plus accrued and
     unpaid cash interest through the Purchase Date or, if the Company has
     previously exercised its option to pay cash interest instead of accreting
     the principal amount of the Securities following a Tax Event, at a purchase
     price equal to the Restated Principal Amount plus any accrued and unpaid
     cash interest through the Purchase Date (the "Purchase Price").  Purchases
     of Securities hereunder shall be made, at the option of the Holder thereof,
     upon:

               (1) 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 20
          Business Days prior to the relevant Purchase Date until one Business
          Day prior to such Purchase Date stating:

                    (A) if Definitive Securities have been issued, the
               certificate number of the Security which the Holder will deliver
               to be purchased or, if Definitive Securities have not been
               issued, such Purchase Notice must comply with appropriate
               Depositary procedures,

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

                    (C) that such Security shall be purchased by the Company as
               of the Purchase Date pursuant to the terms and conditions
               specified in Paragraph 6 of the Securities and in this Indenture,
               and

               1107(b), to pay the Purchase Price in shares of Parent Common
               Stock, in whole or in part, but such portion of the Purchase
               Price is ultimately to be paid to such Holder entirely in cash
               because any of the conditions specified in this Indenture to
               payment of the Purchase Price or portion of the Purchase Price in
               shares of Parent Common Stock is not satisfied prior to the close
               of business on the last day prior to the Purchase Date, as set
               forth in Section 1107(d), whether such Holder elects (i) to
               withdraw such Purchase Notice as to some or all of the Securities
               to which such Purchase Notice relates (stating the principal
               amount and certificate numbers, if any, of the Securities as to
               which such withdrawal shall relate), or (ii) to receive cash in
               respect of the entire Purchase Price for all Securities or
               portions of Securities subject to the Purchase Notice to which
               such Purchase Notice relates; and

                                       9
<PAGE>

               (2) delivery of such Security to the Paying Agent prior to, on or
          after the Purchase Date (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 1107 only if the Security so delivered to the Paying Agent
          shall conform in all respects to the description thereof in the
          related Purchase Notice, as determined by the Company.

          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 1109, fails to indicate such Holder's choice with respect to the
     election set forth in clause (D) of Section 1107(a)(1), such Holder shall
     be deemed to have elected to receive cash in respect of the entire Purchase
     Price for all Securities 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 1107, a portion of a Security, if the principal amount at maturity
     of such portion is $1,000 or an integral multiple of $1,000.  Provisions of
     this Indenture that apply to the purchase of all of a Security also apply
     to the purchase of such portion of such Security.

          Any purchase by the Company contemplated pursuant to the provisions of
     this Section 1107 shall be consummated by the delivery of the consideration
     to be received by the Holder promptly following, but in no event more than
     five Business Days after, the later of the Purchase Date and the time of
     delivery of the Security.  Unless the Company defaults in making payment on
     Securities for which a Purchase Notice has been submitted when due, cash
     interest, if any, on such Securities will cease to accrue and the
     Securities will cease to accrete in value on the Purchase Date.

          Notwithstanding anything herein to the contrary, any Holder delivering
     to the Paying Agent the Purchase Notice contemplated by this Section
     1107(a) shall have the right to withdraw such Purchase Notice at any time
     prior to the close of business one Business Day prior to the Purchase Date
     by delivery of a written notice of withdrawal to the Paying Agent in
     accordance with Section 1109.

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

          (b) Company's Right to Elect Manner of Payment of Purchase Price for
     Payment.  The Securities to be purchased on any Purchase Date pursuant to
     Section 1107(a) may be paid for, in whole or in part, at the election of
     the Company, in U.S. legal tender ("cash") or, subject to the conditions
     set forth in Section 1107(d), shares of Parent Common Stock, or in any
     combination of cash and shares of Parent Common Stock; provided that the
     Company will pay cash for fractional interests in shares of Parent Common
     Stock.  The cash payment for fractional shares will be based on the Closing
     Sales Price of the Parent Common Stock on the trading day immediately prior
     to the Purchase Date.  For purposes of determining the existence of
     potential fractional interests, all Securities subject to purchase by the
     Company held by a Holder shall be considered together (no matter how many

                                      10
<PAGE>

     separate certificates are to be presented). Each Holder whose Securities
     are purchased pursuant to this Section 1107 shall receive the same
     percentage of cash or shares of Parent Common Stock in payment of the
     Purchase Price for such Securities, except (i) as provided in Section
     1107(d) with regard to the payment of cash in lieu of fractional shares of
     Parent Common Stock and (ii) in the event that the Company is unable to
     purchase the Securities of a Holder or Holders for shares of Parent Common
     Stock because any necessary qualifications or registrations of the shares
     of Parent Common Stock under applicable federal or state securities laws
     cannot be obtained, the Company shall purchase the Securities of such
     Holder or Holders for cash. If the Company elects to pay the Purchase Price
     of the Securities with shares of Parent Common Stock or a combination of
     cash and shares of Parent Common Stock, the Company will deliver the
     Company Notice required by Section 1107(e) by the Company Notice Date. 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
     1107(d) in the event of a failure to satisfy, prior to the close of
     business on the last day prior to the Purchase Date, any condition to the
     payment of the Purchase Price, in whole or in part, in shares of Parent
     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 1107(e) in the Company
          Notice,

               (iii)  if the Company elects to pay the Purchase Price, or a
          specified percentage thereof, in shares of Parent Common Stock, that
          the conditions to such manner of payment set forth in Section 1107(d)
          have been or will be complied with and

               (iv) whether the Company desires the Trustee to give the Company
          Notice required by Section 1107(e).

          (c) Purchase with Cash. At the option of the Company, the Purchase
     Price of Securities in respect of which a Purchase Notice pursuant to
     Section 1107(a) has been given may be paid by the Company with cash equal
     to the aggregate Purchase Price of such Securities.

          (d) Payment by Delivery of Shares of Parent Common Stock. At the
     option of the Company, the Purchase Price of Securities in respect of which
     a Purchase Notice pursuant to Section 1107(a) has been given, or a
     specified percentage thereof, may be paid by the Company by the delivery of
     a number of shares of Parent Common Stock equal to the quotient obtained by
     dividing (i) the portion of the Purchase Price to be paid in shares of
     Parent Common Stock by (ii) the Market Price of one share of Parent Common
     Stock as determined by the Company in the Company Notice; provided that the

                                      11
<PAGE>

     Company will pay cash for fractional shares of Parent Common Stock as
     provided in Section 1107(b).

          If the Company elects to purchase the Securities by the issuance of
     shares of Parent Common Stock, the Company Notice, as provided in Section
     1107(e), 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 Securities
     through the issuance of shares of Parent Common Stock shall be conditioned
     upon:

               (i) the Company's timely giving of the Company Notice of an
          election to purchase all or a specified percentage of the Securities
          with shares of Parent Common Stock as provided herein;

               (ii) the registration of such shares of Parent Common Stock under
          the Securities Act, or the Exchange Act, in each case, if required;

               (iii)  the listing of such shares of Parent Common Stock on the
          principal national securities exchange on which the shares of Parent
          Common Stock are listed;

               (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 the shares of Parent Common Stock
          to be delivered by the Company in payment of the Purchase Price in
          respect of Securities are 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 the conditions in clauses (i)
          through (iv) above have been satisfied.

          Such Officers' Certificate shall also set forth the number of shares
     of Parent Common Stock to be issued for each $1,000 principal amount at
     maturity of the Securities.  The Company may pay the Purchase Price (or any
     portion thereof) in shares of Parent Common Stock only if the information
     necessary to calculate the Market Price is published in a daily newspaper
     of national circulation or other widely disseminated public source. If the
     foregoing conditions are not satisfied with respect to a Holder or Holders
     prior to the close of business on the Business Day prior to the Purchase
     Date, and the Company has elected to purchase the Securities pursuant to
     this Section 1107 through the issuance of shares of Parent Common Stock,
     the Company shall pay the entire Purchase Price of the Securities of such
     Holder or Holders in cash.

                                      12
<PAGE>

          The "Market Price" means the average of the Closing Sales Prices of
     the Parent Common Stock for the five trading day period ending on the third
     Business Day prior to the applicable Purchase Date (if the third Business
     Day prior to the applicable Purchase Date is a trading day, or if not, then
     on the last trading day prior to the third Business Day), appropriately
     adjusted to take into account the occurrence, during the period commencing
     on the first of the trading days during the five trading day period and
     ending on the Purchase Date, of any event described in Sections 1406, 1407,
     1408 or 1409 that would require adjustment of the Conversion Rate in
     respect of the Parent Common Stock; subject, however, to the conditions set
     forth in Sections 1410 and 1411.

          The "Closing Sales Price" of Parent Common Stock on any date means the
     closing per share sale price (or, if no closing sales price is reported,
     the average of the bid and ask prices or, if more than one in either case,
     the average of the average bid and the average asked prices) on such date
     as reported in composite transactions for the principal U.S. securities
     exchange on which Parent Common Stock is traded or, if Parent Common Stock
     is not listed on a U.S. national or regional securities exchange, as
     reported by the Nasdaq system.  In the absence of such quotations, the
     Company shall be entitled to determine the Closing Sales Price on the basis
     of such quotations as it considers appropriate.

          Upon determination of the actual number of shares of Parent Common
     Stock to be issued upon repurchase of Securities, the Company will
     disseminate a press release through Reuters Economic Services or Bloomberg
     Business News containing this information or publish the information on the
     Parent's web site or through such other public medium as the Parent may use
     at that time.

          (e) Notice of Election.  If the Company elects to pay the Purchase
     Price of Securities to be purchased pursuant to Section 1107(a) with shares
     of Parent Common Stock or a combination of cash and shares of Parent Common
     Stock, the Company shall give notice to Holders setting forth information
     specified in this Section 1107(e) (the "Company Notice").  The Company
     Notice shall:

               (1) state that each Holder will receive shares of Parent Common
          Stock with a Market Price determined as of a specified date prior to
          the Purchase Date equal to the Purchase Price of the Securities held
          by such Holder or a specified percentage thereof (except any cash
          amount to be paid in lieu of fractional shares);

               (2) set forth the method of calculating the Market Price of the
          shares of Parent Common Stock;

               (3) state that because the Market Price of shares of Parent
          Common Stock will be determined prior to the Purchase Date, Holders of
          the Securities will bear the market risk with respect to the value of
          the shares of Parent Common Stock to be received from the date such
          Market Price is determined to the Purchase Date; and

                                  13
<PAGE>

               (4) set forth the procedures that a Holder must follow to
          exercise its put rights under this Section 1107 and the procedures for
          withdrawing a Purchase Notice (including, without limitation, a
          conditional withdrawal pursuant to the terms of Section 1107(a)(1)(D)
          or Section 1109).

          The Company Notice shall be sent to Holders (and to beneficial owners
     as required by applicable law) not less than 20 Business Days prior to the
     Purchase Date (the "Company Notice Date").

          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.

          Simultaneously with such Company Notice, the Company shall disseminate
     a press release through Reuters Economic Services or Bloomberg Business
     News containing this information or publish the information on the Parent's
     web site or through such other public medium as the Parent may use at that
     time.

          (f) Covenants of the Company.  All shares of Parent Common Stock
     delivered upon purchase of the Securities 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.

          (g) Procedure upon Purchase. The Company shall deposit cash (in
     respect of a cash purchases under this Section 1107 or for fractional
     interests, as applicable) or shares of Parent Common Stock, or a
     combination thereof, as applicable, at the time and in the manner as
     provided in Section 1110, sufficient to pay the aggregate Purchase Price of
     all Securities to be purchased pursuant to this Section 1107.  As soon as
     practicable after the Purchase Date, the Company shall deliver to each
     Holder entitled to receive shares of Parent Common Stock through the Paying
     Agent, a certificate for the number of full shares of Parent 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 Parent Common Stock is registered shall be treated as a holder of
     record of Parent Common Stock on the Business Day following the Purchase
     Date. Subject to Section 1107(d), no payment or adjustment will be made for
     dividends on the shares of Parent Common Stock the record date for which
     occurred on or prior to the Purchase Date.

          (h) Taxes.  If a Holder of a purchased Security is paid in shares of
     Parent Common Stock, the Company shall pay any documentary, stamp or
     similar issue or transfer tax due on such issue of Parent Common Stock.
     However, the Holder shall pay any such tax which is due because the Holder
     requests the Parent 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 Parent 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 Parent 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 1108.  Purchase of Securities at Option of the Holder upon Change
     in Control.

          (a) If a Change in Control occurs, the Securities not previously
     purchased by the Company or any portion of the principal amount thereof
     shall be purchased by the Company, at the option of the Holder thereof, at
     a purchase price equal to the Accreted Principal Amount plus any accrued
     and unpaid cash interest to the date that is 45 days after the date the
     Company shall have mailed notice of the occurrence of a Change in Control
     pursuant to Section 1108(b) (the "Change in Control Purchase Date") or, if
     the Company has previously exercised its option to pay cash interest
     instead of accreting the principal amount of the Securities following a Tax
     Event, at a purchase price equal to the Restated Principal Amount plus any
     accrued and unpaid cash interest to the Change in Control Purchase Date
     (the "Change in Control Purchase Price"), subject to satisfaction by or on
     behalf of the Holder of the requirements set forth in Section 1108(c).

          A "Change in Control" shall be deemed to have occurred at such time
     after the Securities are originally issued as either of the following
     events shall occur:

               (i) any person, including any syndicate or group deemed to be a
          "person" under Section 13(d)(3) of the Exchange Act, acquires
          beneficial ownership, directly or indirectly, through a purchase,
          merger or other acquisition transaction or series of transactions, of
          shares of Parent Common Stock entitling the person to exercise 50% or
          more of the total voting power of all shares of the Parent Common
          Stock that is entitled to vote generally in elections of directors,
          other than an acquisition by the Parent, any of its Subsidiaries or
          any of its employee benefit plans; or

               (ii) the Parent merges or consolidates with or into any other
          person, any merger of another person into the Parent, or the Parent
          conveys, sells, transfers or leases all or substantially all of its
          assets to another person, other than any transaction: (A) that does
          not result in any reclassification, conversion, exchange or
          cancellation of outstanding shares of the Parent's Capital Stock, (B)
          pursuant to which the holders of Parent Common Stock immediately prior
          to the transaction have the entitlement to exercise, directly or
          indirectly, 50% or more of the total voting power of all shares of
          Parent Common Stock entitled to vote generally in the election of
          directors of the continuing or surviving corporation immediately after
          the transaction or (C) which is effected solely to change the Parent's
          jurisdiction of incorporation and results in a reclassification,
          conversion or exchange of outstanding shares of Parent Common Stock
          solely into shares of common stock of the surviving corporation.

     Notwithstanding the foregoing provisions of this Section 1108, a Change in
     Control shall not be deemed to have occurred if (A) the Closing Sales Price
     of Parent Common Stock for any five trading days within the period of 10
     consecutive trading days ending immediately after the later of the Change
     in Control or the public announcement of the Change in Control, in the case
     of a Change in Control relating to an acquisition of Capital Stock, or the
     period of 10 consecutive trading days ending immediately before the Change

                                      15
<PAGE>

     in Control, in the case of a Change in Control relating to a merger,
     consolidation or asset sale, equals or exceeds 105% of the Accreted
     Conversion Price of the Securities in effect on each of those trading days
     or (B) all of the consideration in a merger or consolidation otherwise
     constituting a Change in Control under clause (i) and/or clause (ii) above
     (other than cash payments not to exceed 5% of the total value of such
     merger or consolidation (excluding cash payments for fractional shares and
     cash payments made pursuant to dissenters' appraisal rights)) consists of
     shares of common stock traded on a national securities exchange or quoted
     on the Nasdaq National Market (or will be so traded or quoted immediately
     following the merger or consolidation) and as a result of the merger or
     consolidation the Securities become convertible into common stock of the
     surviving corporation.

          For purposes of this Section 1108, whether a person is a "beneficial
     owner" shall be determined in accordance with Rule 13d-3 under the Exchange
     Act and "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 30 days after the occurrence of a Change in Control,
     the Company shall mail a written notice of the Change in Control by first-
     class mail to the Trustee and to each Holder (and to beneficial owners as
     required by applicable law).  The notice shall include a form of Change in
     Control Purchase Notice to be completed by the Holder and shall state:

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

               (2)  the date by which the Change in Control Purchase Notice
                    pursuant to this Section 1108 must be given;

               (3)  the Change in Control Purchase Date;

               (4)  the Change in Control Purchase Price;

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

               (6)  that the Securities as to which a Change in Control Purchase
                    Notice has been given may be converted if they are otherwise
                    convertible pursuant to Article Fourteen hereof only if the
                    Change in Control Purchase Notice has been withdrawn in
                    accordance with the terms of this Indenture;

               (7)  the procedures for withdrawing a Change in Control Purchase
                    Notice;

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

                                      16
<PAGE>

               (9)  that the Change in Control Purchase Price for any Security
                    as to which a Change in Control Purchase Notice has been
                    duly given and not withdrawn will be paid promptly following
                    the later of the Change in Control Purchase Date and the
                    time of surrender of such Security;

               (10) that, unless the Company defaults in making payment of such
                    Change in Control Purchase Price when due, cash interest, if
                    any, on Securities surrendered for purchase by the Company
                    will cease to accrue and the Securities will cease to
                    accrete in value on and after the Change in Control Purchase
                    Date; and

               (11) the CUSIP number(s) of the Securities.

          (c) In order to exercise its rights specified in Section 1108(a), a
     Holder must deliver a written notice requesting purchase of all or a
     portion of its Securities (a "Change in Control Purchase Notice") to the
     Paying Agent at any time on or prior to the 30th day after the date the
     Company delivers its written notice of the occurrence of a Change in
     Control, stating:

               (1)  the certificate number(s) of the Securities which the Holder
                    will deliver to be purchased or, if Definitive Securities
                    have not been issued, such information as shall be provided
                    pursuant to appropriate Depositary procedures;

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

               (3)  that such Security shall be purchased pursuant to the terms
                    and conditions specified in Paragraph 6 of the Securities.

          The timely delivery to the Paying Agent of the Change in Control
     Purchase Notice and the delivery of such Security (together with all
     necessary endorsements) at the offices of the Paying Agent shall be a
     condition to the receipt by the Holder of the Change in Control Purchase
     Price therefor; provided, however, that, in the case of delivery of such
     Security to the Paying Agent, such Change in Control Purchase Price shall
     be so paid pursuant to this Section 1108 only if the Security so delivered
     to the Paying Agent shall conform in all respects to the description
     thereof set forth in the related Change in Control Purchase Notice.

          The Company shall purchase from the Holder thereof, pursuant to this
     Section 1108, a portion of a Security if the principal amount at maturity
     of such portion is $1,000 or an integral multiple of $1,000. Provisions of
     this Indenture that apply to the purchase of all of a Security also apply
     to the purchase of such portion of such Security.

                                      17
<PAGE>

          Any purchase by the Company contemplated pursuant to the provisions of
     this Section 1108 shall be consummated by the delivery of the consideration
     to be received by the Holder on the Change of Control Purchase Date.

          Notwithstanding anything herein to the contrary, any Holder delivering
     to the Paying Agent the Change in Control Purchase Notice contemplated by
     this Section 1108(c) shall have the right to withdraw such Change in
     Control Purchase Notice at any time prior to the close of business one
     Business Day prior to the Change in Control Purchase Date by delivery of a
     written notice of withdrawal to the Paying Agent in accordance with Section
     1109.

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

     SECTION 1109.  Effect of Purchase Notice or Change in Control Purchase
     Notice.

          Upon receipt by the Paying Agent of the Purchase Notice or Change in
     Control Purchase Notice specified in Section 1107(a) or Section 1108(c), as
     applicable, the Holder of the Security in respect of which such Purchase
     Notice or Change in Control Purchase Notice, as the case may be, was given
     shall (unless such Purchase Notice or Change in Control Purchase Notice, as
     the case may be, is withdrawn as specified in the following two paragraphs)
     thereafter be entitled to receive solely the Purchase Price or Change in
     Control Purchase Price, as the case may be, with respect to such Security.
     Such Purchase Price shall be paid to such Holder, subject to receipts of
     funds and/or securities by the Paying Agent, promptly following, but in no
     event more than five Business Days after, the later of (x) the Purchase
     Date with respect to such Security (provided that the conditions in Section
     1107(a) have been satisfied) and (y) the time of delivery of such Security
     to the Paying Agent by the Holder thereof in the manner required by Section
     1107(a), and such Change in Control Purchase Price shall be paid to such
     Holder, subject to receipts of funds and/or securities by the Paying Agent,
     on the later of (x) the Change in Control Purchase Date with respect to
     such Security (provided that the conditions in Section 1108(c) have been
     satisfied) and (y) the time of delivery of such Security to the Paying
     Agent by the Holder thereof in the manner required by Section 1108(c).
     Securities in respect of which a Purchase Notice or Change in Control
     Purchase Notice has been given by the Holder thereof may not be converted
     pursuant to Article Fourteen hereof on or after the date of the delivery of
     such Purchase Notice or Change in Control Purchase Notice unless such
     Purchase Notice or Change in Control Purchase Notice has first been validly
     withdrawn as specified in the following paragraph.

          A Purchase Notice or Change in Control Purchase Notice may be
     withdrawn by the Holder by means of a written notice of withdrawal
     delivered to the office of the Paying Agent at any time prior to the close
     of business one Business Day prior to the Purchase Date or the Change in
     Control Purchase Date, as the case may be, specifying:

               (1)  the certificate number, if any, of the Security in respect
                    of which such notice of withdrawal is being submitted or, if
                    Definitive Securities have not been issued, such information

                                      18
<PAGE>

                    as shall be provided pursuant to appropriate Depositary
                    procedures,

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

               (3)  the principal amount at maturity, if any, of such Security
                    which remains subject to the original Purchase Notice or
                    Change in Control Purchase Notice, as the case may be, and
                    which has been or will be delivered for purchase by the
                    Company.

          There shall be no purchase of any Securities pursuant to Section 1107
     or 1108 if there has occurred (prior to, on or after, as the case may be,
     the giving, by the Holders of such Securities, of the required Purchase
     Notice or Change in Control 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 Change in Control Purchase Price, as the case may be,
     with respect to such Securities). The Paying Agent will promptly return to
     the respective Holders thereof any Securities (x) with respect to which a
     Purchase Notice or Change in Control Purchase Notice, as the case may be,
     has been withdrawn in compliance with this 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 Change in Control Purchase Price, as the
     case may be, with respect to such Securities) in which case, upon such
     return, the Purchase Notice or Change in Control Purchase Notice with
     respect thereto shall be deemed to have been withdrawn.

     SECTION 1110.  Deposit of Purchase Price or Change in Control Purchase
     Price.

          Prior to 10:00 a.m. (local time in the City of New York) on the fifth
     Business Day following the Purchase Date or prior to 10:00 a.m. (local time
     in the City of New York) on the Change in Control Purchase Date, as the
     case may be, the Company shall deposit 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 Section 606)
     an amount of cash (in immediately available funds if deposited on such
     Business Day) or Parent Common Stock, if permitted hereunder, or both,
     sufficient to pay the aggregate Purchase Price or Change in Control
     Purchase Price, as the case may be, of all the Securities or portions
     thereof which are to be purchased as of the Purchase Date or Change in
     Control Purchase Date, as the case may be.

     SECTION 1111.  Securities Purchased in Part.

          Any Security 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 Security, without service charge, a new
     Security or Securities, of any authorized denomination as requested by such
     Holder in aggregate principal amount equal to, and in exchange for, the

                                      19
<PAGE>

     portion of the
     principal amount of the Security so surrendered which is not purchased.

     SECTION 1112.  Repayment to the Company.

          The Paying Agent and the Trustee shall return to the Company any cash
     or shares of Parent Common Stock that remain unclaimed for two years,
     subject to applicable unclaimed property laws, held by them for the payment
     of the Purchase Price or Change in Control Purchase Price, as the case may
     be; provided, however, that to the extent that the aggregate amount of cash
     or shares of Parent Common Stock deposited by the Company pursuant to
     Section 1110 exceeds the aggregate Purchase Price or Change in Control
     Purchase Price, as the case may be, of the Securities or portions thereof
     which the Company is obligated to purchase as of the Purchase Date or
     Change in Control 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 Change in Control Purchase Date, as the case
     may be, the Paying Agent and the Trustee shall return any such excess to
     the Company.

SECTION 2.04.  Conversion.

     The Original Indenture is hereby amended, with respect to the Notes only,
by adding a new Article Fourteen immediately following Article Thirteen of the
Original Indenture, to read as follows:

                                  ARTICLE XIV

                                  CONVERSION

     SECTION 1401.  Conversion Privilege.

          A Holder of a Security may convert such Security into shares of Parent
     Common Stock at any time during the periods stated in paragraph 7 of the
     Securities.  The number of shares of Parent Common Stock issuable upon
     conversion of a Security per $1,000 of principal amount at maturity thereof
     (the "Conversion Rate") shall be that set forth in paragraph 7 in the
     Securities, subject to adjustment as herein set forth.

          A Holder may convert a portion of the principal amount at maturity of
     a Security if the portion is $1,000 or an integral multiple of $1,000.
     Provisions of this Indenture that apply to conversion of all of a Security
     also apply to conversion of a portion of the Security.

     SECTION 1402.  Conversion Procedure.

          To convert a Security, a Holder must satisfy the requirements in
     paragraph 7 of the Securities.  The first Business Day on which the Holder
     satisfies all those requirements is the conversion date (the "Conversion
     Date").  As soon as practicable after the Conversion Date, the Company
     shall deliver to the Holder, through the Conversion Agent, a certificate
     for the number of whole shares of Parent Common Stock issuable upon the

                                      20
<PAGE>

     conversion and cash in lieu of any fractional share determined pursuant to
     Section 1403. The Person in whose name the certificate is registered shall
     be treated as the stockholder of record as of the close of business on the
     Conversion Date. Upon conversion of a Security, such Person shall no longer
     be a Holder of such Security.

          No payment or adjustment will be made for dividends on, or other
     distributions with respect to, any Parent Common Stock except as provided
     in this Article Fourteen.  On conversion of a Security, no accrued and
     unpaid cash interest, if any, or amounts reflecting accretion of the
     Securities included in the Accreted Principal Amount or the Restated
     Principal Amount (as the case may be), in each case through the Conversion
     Date, will be payable with respect to the converted Security and no such
     cash interest or amounts reflecting accretion of the Securities shall be
     deemed to be canceled, extinguished or forfeited, but rather shall be
     deemed to be paid in full to the Holder thereof through delivery of the
     shares of Parent Common Stock (together with the cash payment, if any, in
     lieu of fractional shares) in exchange for the Security being converted
     pursuant to the provisions hereof; and the fair market value of such shares
     of Parent Common Stock (together with any such cash payment in lieu of
     fractional shares) shall be treated as issued, to the extent thereof, first
     in exchange for accrued and unpaid cash interest, if any, through the
     Conversion Date, and the balance, if any, of such fair market value of such
     shares of Parent Common Stock (and any such cash payment) shall be treated
     as issued for the Accreted Principal Amount or the Restated Principal
     Amount (as the case may be) of the Security being converted pursuant to the
     provisions hereof.  The Company will not adjust the conversion ratio to
     account for accrued and unpaid cash interest, if any, or for amounts
     reflecting accretion of the Securities included in the Accreted Principal
     Amount or the Restated Principal Amount (as the case may be).  If a Holder
     converts more than one Security at the same time, the number of shares of
     Parent Common Stock issuable upon the conversion shall be based on the
     total principal amount of the Securities converted.

          If the last day on which a Security may be converted is a not a
     Business Day in a place where a Conversion Agent is located, the Security
     may be surrendered on the next succeeding day that is a Business Day.

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

          If a Holder submits a Security for conversion after the Company has
     elected to exercise its option to pay cash interest instead of accreting
     the principal amount of the Securities following a Tax Event, or if the
     Company is required to make a cash payment pursuant to an increased
     accretion rate, in either case between a record date and the opening of
     business on the next Interest Payment Date (except for Securities or
     portions of Securities called for redemption on a Purchase Date occurring
     during the period from the close of business on a record date and ending on
     the close of business on the next Interest Payment Date, or if such
     Interest Payment Date is not a Business Day, the next Business Day after

                                      21
<PAGE>

     the Interest Payment Date), such Holder shall pay to the Company an amount
     equal to cash interest payable on the converted principal amount.

     SECTION 1403.  Fractional Shares.

          Holders will not receive fractional shares upon conversion of a
     Security.  Instead, the Holder will receive a cash payment for fractional
     shares based on the Closing Sales Price of the Parent Common Stock on the
     trading day immediately preceding the Conversion Date.

     SECTION 1404.  Taxes on Conversion.

          If a Holder submits a Security for conversion, the Company shall pay
     any documentary, stamp or similar issue or transfer tax due on the delivery
     of shares of Parent Common Stock upon the conversion.  However, the Holder
     shall pay any such tax which is due because the Holder requests the shares
     to be registered in a name other than the Holder's name.  The Conversion
     Agent may refuse to deliver the certificates representing the shares of
     Parent Common Stock being registered 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 registered in a name other than
     the Holder's name.  Nothing herein shall preclude any tax withholding
     required by law or regulations.

     SECTION 1405.  Parent Common Stock.

          All shares of Parent Common Stock delivered by the Conversion Agent on
     behalf of the Company upon conversion of the Securities shall be duly and
     validly issued and fully paid and nonassessable, and shall be free from
     preemptive rights and free of any lien or adverse claim.  Each of the
     Company and the Parent will endeavor promptly to comply with all federal
     and state securities laws regulating the offer and delivery of shares of
     Parent Common Stock upon conversion of Securities, if any, and the Parent
     will list or cause to have quoted such shares of Parent Common Stock on
     each national securities exchange or in the over-the-counter market or such
     other market on which the shares of Parent Common Stock are then listed or
     quoted.

     SECTION 1406.  Adjustment for Change in Capital Stock.

          If, after the Issue Date of the Securities, the Parent:

               (1) pays a dividend or makes another distribution to all holders
          of the Parent Common Stock on the Parent Common Stock payable
          exclusively in shares of Parent Common Stock;

               (2) subdivides the outstanding shares of Parent Common Stock into
          a greater number of shares of Parent Common Stock;

               (3) combines the outstanding shares of Parent Common Stock into a
          smaller number of shares Parent Common Stock; or

                                      22
<PAGE>

               (4) pays a dividend or makes other distributions to all holders
          of the Parent Common Stock consisting of Capital Stock of the Parent
          (other than those rights and warrants referred to in Section 1411
          relating to stockholders rights plans),

     then the Conversion Rate in effect immediately prior to such action shall
     be adjusted so that the Holder of a Security thereafter converted will
     receive the number of shares of Capital Stock of the Parent which such
     Holder would have owned immediately following such action if such Holder
     had converted the Security immediately prior to such action.

          The adjustment shall become effective immediately after the record
     date in the case of a dividend or distribution and immediately after the
     effective date in the case of a subdivision, combination or
     reclassification.

          If after an adjustment a Holder of a Security upon conversion of such
     Security may receive shares of two or more classes of Capital Stock of the
     Parent, the Conversion Rate shall thereafter be subject to adjustment upon
     the occurrence of an action taken with respect to any such class of Capital
     Stock as is contemplated by this Article Fourteen with respect to the
     shares of Parent Common Stock, on terms comparable to those applicable to
     shares of Parent Common Stock in this Article Fourteen.

     SECTION 1407.  Adjustment for Rights Issue.

          If after the Issue Date of the Securities, the Parent distributes any
     rights or warrants to all holders of shares of its Parent Common Stock
     entitling them to purchase shares of Parent Common Stock at a price per
     share less than the Average Sale Price as of the Time of Determination, the
     Conversion Rate shall be adjusted in accordance with the formula:

          R'  =  R  x        (O + N)
                       -------------------
                         (O + (N x P)/M)

          where:

          R' =   the adjusted Conversion Rate.

          R  =   the current Conversion Rate.

          O  =   the number of shares of Parent Common Stock outstanding on the
                 record date for the distribution to which this Section 1407 is
                 being applied.

          N  =   the number of additional shares of Parent Common Stock offered
                 pursuant to the distribution.

          P  =   the offering price per share of the additional shares.

          M =    the Average Sale Price, minus, in the case of (i) a
                 distribution to which Section 1406(4) applies or (ii) a
                 distribution to which Section 1408 applies, for which, in each

                                      23
<PAGE>

                 case, (x) the record date shall occur on or before the record
                 date for the distribution to which this Section 1407 applies
                 and (y) the Ex-Dividend Time shall occur on or after the date
                 of the Time of Determination for the distribution to which this
                 Section 1407 applies, the fair market value (on the record date
                 for the distribution to which this Section 1407 applies) of:

                  (1) the Capital Stock of the Parent distributed in respect of
              each share of Parent Common Stock in such Section 1406(4)
              distribution; and

                  (2) the assets of the Parent or debt securities or any rights,
              warrants or options to purchase securities of the Parent
              distributed in respect of each share of Parent Common Stock in
              such Section 1408 distribution.

          The Board of Directors shall determine fair market values for the
     purposes of this Section 1407, except as Section 1408 otherwise provides in
     the case of a Spin-off.

          "Average Sale Price" means the average of the Closing Sales Prices of
     the shares of Parent Common Stock for the shorter of:

               (i) 30 consecutive trading days ending on the last full trading
          day prior to the Time of Determination with respect to the rights,
          warrants or options or distribution in respect of which the Average
          Sale Price is being calculated;

               (ii) the period (x) commencing on the date next succeeding the
          first public announcement of (a) the issuance of rights, warrants or
          options or (b) the distribution, in each case, in respect of which the
          Average Sale Price is being calculated and (y) proceeding through the
          last full trading day prior to the Time of Determination with respect
          to the rights, warrants or options or distribution in respect of which
          the Average Sale Price is being calculated (excluding days within such
          period, if any, which are not trading days); or

               (iii)  the period, if any, (x) commencing on the date next
          succeeding the Ex-Dividend Time with respect to the next preceding (a)
          issuance of rights, warrants or options or (b) distribution, in each
          case, for which an adjustment is required by the provisions of Section
          1406(4), 1407, 1408 or 1409 and (y) proceeding through the last full
          trading day prior to the Time of Determination with respect to the
          rights, warrants or options or distribution in respect of which the
          Average Sale Price is being calculated (excluding days within such
          period, if any, which are not trading days).

          In the event that the Ex-Dividend Time (or in the case of a
     subdivision, combination or reclassification, the effective date with
     respect thereto) with respect to a dividend, subdivision, combination or
     reclassification to which Section 1406(1), (2) or (3) applies occurs during
     the period applicable for calculating "Average Sale Price" pursuant to the
     definition in the preceding sentence, "Average Sale Price" shall be
     calculated for such period in a manner determined by the Board of Directors
     to reflect the impact of such dividend, subdivision, combination or

                                      24
<PAGE>

     reclassification on the Closing Sales Price of the shares of Parent Common
     Stock during such period.

          "Time of Determination" means the time and date of the earlier of (i)
     the determination of shareholders entitled to receive rights, warrants or
     options or a distribution, in each case, to which Section 1407 or 1408
     applies and (ii) the Ex-Dividend Time.

          "Ex-Dividend Time" means the time immediately prior to the
     commencement of "ex-dividend" trading for such rights, warrants or options
     or distribution on a national or regional exchange or market on which the
     shares of Parent Common Stock are then listed or quoted.

          The adjustment shall become effective immediately after the record
     date for the determination of shareholders entitled to receive the rights,
     warrants or options to which this Section 1407 applies.  If all of the
     shares of Parent Common Stock subject to such rights, warrants or options
     have not been issued when such rights, warrants or options expire, then the
     Conversion Rate shall promptly be readjusted to the Conversion Rate which
     would then be in effect had the adjustment upon the issuance of such
     rights, warrants or options been made on the basis of the actual number of
     shares of Parent Common Stock issued upon the exercise of such rights,
     warrants or options.

          No adjustment shall be made under this Section 1407 if the application
     of the formula stated above in this Section 1407 would result in a value of
     R' that is equal to or less than the value of R.

     SECTION 1408.  Adjustment for Other Distributions.

          If, after the Issue Date of the Securities, the Parent distributes to
     all holders of its shares of Parent Common Stock any of its debt,
     securities or assets or any rights, warrants or options to purchase
     securities of the Parent (including securities or cash, but excluding (x)
     distributions of Capital Stock referred to in Section 1406 and
     distributions of rights, warrants or options referred to in Section 1407
     and (y) cash dividends or other cash distributions unless such cash
     dividends or other cash distributions are Extraordinary Cash Dividends) the
     Conversion Rate shall be adjusted, subject to the provisions of the last
     paragraph of this Section 1408, in accordance with the formula:

          R' =  R x M
                -----
                (M - F)

          where:

          R' = the adjusted Conversion Rate.

          R  = the current Conversion Rate.

          M  = the Average Sale Price, minus, in the case of a distribution to
               which Section 1406(4) applies, for which (i) the record date
               shall occur on or before the record date for the distribution

                                      25
<PAGE>

               to which this Section 1408 applies and (ii) the Ex-Dividend Time
               shall occur on or after the date of the Time of Determination for
               the distribution to which this Section 1408 applies, the fair
               market value (on the record date for the distribution to which
               this Section 1408 applies) of any Capital Stock of the Parent
               distributed in respect of each share of Parent Common Stock in
               such Section 1406(4) distribution.

          F =  the fair market value (on the record date for the distribution to
               which this Section 1408 applies) of the assets, securities,
               rights, warrants or options to be distributed in respect of each
               share of Parent Common Stock in the distribution to which this
               Section 1408 is being applied (including, in the case of cash
               dividends or other cash distributions giving rise to an
               adjustment, all such cash distributed concurrently).

          In the event the Parent distributes shares of Capital Stock of a
     Subsidiary, the Conversion Rate will be adjusted, if at all, based on the
     market value of the Subsidiary stock so distributed relative to the market
     value of the Parent Common Stock, as discussed below.  The Board of
     Directors shall determine fair market values for the purposes of this
     Section 1408, except that in respect of a dividend or other distribution of
     shares of Capital Stock of any class or series, or similar equity
     interests, of or relating to a Subsidiary or other business unit of the
     Parent (a "Spin-off"), the fair market value of the securities to be
     distributed shall equal the average of the daily Closing Sales Prices of
     those securities for the five consecutive trading days commencing on and
     including the sixth day of trading of those securities after the
     effectiveness of the Spin-off and the average of the Closing Sales Prices
     shall mean the average Closing Sales Prices for the Parent Common Stock for
     the same five trading days.  In the event, however, that an underwritten
     initial public offering of the securities in the Spin-off occurs
     simultaneously with the Spin-off, fair market value of the securities
     distributed in the Spin-off shall mean the initial public offering price of
     such securities and the Average Sale Price, for purposes of this sentence,
     shall mean the Closing Sales Price for the Parent Common Stock on the same
     trading day.

          Assuming that a distribution referred to in this Section 1408 shall
     have occurred, the adjustment referred to in this Section 1408 shall become
     effective as of a date and time immediately after the record date for the
     determination of shareholders entitled to receive the distribution to which
     this Section 1408 applies, except that an adjustment related to a Spin-off
     shall become effective at the earlier to occur of (i) 10 trading days after
     the effective date of the Spin-off and (ii) the initial public offering of
     the securities distributed in the Spin-off.

          For purposes of this Section 1408, the term "Extraordinary Cash
     Dividend" shall mean any all-cash distributions in an aggregate amount
     that, together with (i) any cash and the fair market value of any other
     consideration payable in respect of any tender offer by the Parent or any
     of its Subsidiaries for shares of Parent Common Stock consummated within
     the preceding 12 months not triggering a Conversion Rate adjustment and
     (ii) all other all-cash distributions to all or substantially all holders
     of Parent Common Stock made within the preceding 12 months not triggering a
     Conversion Rate adjustment, exceeds an amount equal to 15% of the market

                                      26
<PAGE>

     capitalization of Parent Common Stock on the Business Day immediately
     preceding the day on which the Parent declares the distribution.

          If, upon the date prior to the Ex-Dividend Time with respect to a cash
     dividend on the shares of Parent Common Stock, the aggregate amount of such
     cash dividend together with the amounts of all other cash dividends or cash
     distributions gives rise to an adjustment of the Conversion Rate pursuant
     to Section 1406, then such cash dividend together with all such other cash
     dividends or cash distributions shall, for purposes of applying the formula
     set forth above in this Section 1408, cause the value of "F" to equal (y)
     the aggregate amount of such cash dividend together with the amounts of
     such other cash dividends or cash distributions, minus (z) the aggregate
     amount of all cash dividends or cash distributions for which a prior
     adjustment in the Conversion Rate was previously made.

          In the event that, with respect to any distribution to which this
     Section 1408 would otherwise apply, the difference "M-F" as defined in the
     above formula is less than $1.00 or "F" is equal to or greater than "M",
     then the adjustment provided by this Section 1408 shall not be made and in
     lieu thereof the provisions of Section 1415 shall apply to such
     distribution.

          SECTION 1409.  Adjustment for Self-Tender Offer.

          If, after the Issue Date of the Securities, the Parent or any
     Subsidiary of the Parent pays holders of the Parent Common Stock in respect
     of a tender or exchange offer, other than an odd-lot offer, by the Parent
     or any of its Subsidiaries for Parent Common Stock to the extent that the
     offer involves aggregate consideration that, together with (i) any cash and
     the fair market value of any other consideration payable in respect of any
     tender offer by the Parent or any of its Subsidiaries for shares of Parent
     Common Stock consummated within the preceding 12 months not triggering a
     Conversion Rate adjustment and (ii) all-cash distributions to all or
     substantially all holders of Parent Common Stock made within the preceding
     12 months not triggering a Conversion Rate adjustment, exceeds an amount
     equal to 15% of the market capitalization of Parent Common Stock on the
     expiration date of the tender offer, the Conversion Rate shall be adjusted
     in an equitable manner, as determined by the Parent's Board of Directors in
     consultation with Goldman, Sachs & Co. or such other nationally recognized
     investment banking institution satisfactory to the Parent.

     SECTION 1410.  When Adjustment May Be Deferred.

          No adjustment in the Conversion Rate need be made unless the
     adjustment would require an increase or decrease of at least 1% in the
     Conversion Rate.  Any adjustments that are not made shall be carried
     forward and taken into account in any subsequent adjustment.

          All calculations under this Article Fourteen shall be made to the
     nearest cent or to the nearest 1/1,000th of a share, as the case may be.

                                      27
<PAGE>

     SECTION 1411.  When No Adjustment Is Required.

          If the Parent adopts a stockholders rights plan under which the Parent
     issues rights providing that each share of Parent Common Stock issued upon
     conversion of the Security at any time prior to the distribution of
     separate certificates representing the rights will be entitled to receive
     the rights, no adjustment need be made as a result of:  (i) the issuance of
     the rights; (ii) the distribution of separate certificates representing the
     rights; (iii) the exercise or redemption of the rights in accordance with
     any rights agreement; or (iv) the termination or invalidation of the
     rights.

          No adjustment need be made for a transaction referred to in Section
     1407 if Holders of the Securities may participate in the transaction on a
     basis and with notice that the Board of Directors determines to be fair and
     appropriate in light of the basis and notice on which holders of shares of
     Parent Common Stock participate in the transaction.  No adjustment need be
     made for a transaction referred to in Section 1408 if all Holders of the
     Securities may participate in the transaction.

          No adjustment need be made for a change in the par value or no par
     value of the shares of Parent Common Stock.

          To the extent the Securities become convertible pursuant to this
     Article Fourteen in whole or in part into cash, no adjustment need be made
     thereafter as to the cash.  Interest will not accrue on the cash.

     SECTION 1412.  Notice of Adjustment.

          Whenever the Conversion Rate is adjusted, the Company shall promptly
     mail to Holders a notice of the adjustment.  The Company shall file with
     the Trustee and the Conversion Agent such notice and a certificate from the
     Company's independent public accountants briefly stating the facts
     requiring the adjustment and the manner of computing it.  The certificate
     shall be conclusive evidence that the adjustment is correct.  Neither the
     Trustee nor any Conversion Agent shall be under any duty or responsibility
     with respect to any such certificate except to exhibit the same to any
     Holder desiring inspection thereof.

     SECTION 1413.  Voluntary Increase.

          The Company from time to time may increase the Conversion Rate by any
     amount at any time for at least 20 days, so long as the increase is
     irrevocable during such period.  Whenever the Conversion Rate is increased,
     the Company shall mail to Holders and file with the Trustee and the
     Conversion Agent a notice of the increase.  The Company shall mail the
     notice at least 15 days before the date the increased Conversion Rate takes
     effect. The notice shall state the increased Conversion Rate and the period
     it will be in effect.  A voluntary increase of the Conversion Rate does not
     change or adjust the Conversion Rate otherwise in effect for purposes of
     Section 1406, 1407, 1408 or 1409.

                                      28
<PAGE>

     SECTION 1414.  Notice of Certain Transactions.

          If:

          (1) the Parent takes any action that would require an adjustment in
     the Conversion Rate pursuant to Section 1406, 1407, 1408 or 1409 (unless no
     adjustment is to occur pursuant to Section 1411); or

          (2) the Parent takes any action that would require a supplemental
     indenture pursuant to Section 1415; or

          (3) there is a liquidation or dissolution of the Parent;

     then the Company shall mail to Holders and file with the Trustee and the
     Conversion Agent a notice stating the proposed record date for a dividend
     or distribution or the proposed effective date of a subdivision,
     combination, reclassification, consolidation, merger, binding share
     exchange, transfer, liquidation or dissolution.  The Company shall file and
     mail the notice at least 15 days before such date.  Failure to file or mail
     the notice or any defect in it shall not affect the validity of the
     transaction.

     SECTION 1415.  Reorganization of the Parent.

          If the Parent is a party to a transaction subject to Section 801
     (other than a sale of all or substantially all of the assets of the Parent
     in a transaction in which the holders of shares of Parent Common Stock
     immediately prior to such transaction do not receive securities, cash or
     other assets of the Parent or any other person) or a merger or binding
     share exchange which reclassifies or changes its outstanding shares of
     Parent Common Stock, the person obligated to deliver securities, cash or
     other assets upon conversion of Securities shall enter into a supplemental
     indenture.  If the issuer of securities deliverable upon conversion of
     Securities is an Affiliate of the successor company, that issuer shall join
     in the supplemental indenture.

          The supplemental indenture shall provide that the Holder of a Security
     may convert it into the kind and amount of securities, cash or other assets
     which such Holder would have received immediately after the consolidation,
     merger, binding share exchange or transfer if such Holder had converted the
     Security immediately before the effective date of the transaction, assuming
     (to the extent applicable) that such Holder (i) was not a constituent
     person or an Affiliate of a constituent person to such transaction; (ii)
     made no election with respect thereto; and (iii) was treated alike with the
     plurality of non-electing Holders. The supplemental indenture shall provide
     for adjustments which shall be as nearly equivalent as may be practical to
     the adjustments provided for in this Article Fourteen.  The successor
     company shall mail to Holders a notice briefly describing the supplemental
     indenture.

          If this Section applies, neither Section 1406 nor Section 1407
     applies.


                                      29
<PAGE>

          If the Parent makes a distribution to all holders of its shares of
     Parent Common Stock of any of its assets, or debt securities or any rights,
     warrants or options to purchase securities of the Parent that, but for the
     provisions of the last paragraph of Section 1408, would otherwise result in
     an adjustment in the Conversion Rate pursuant to the provisions of Section
     1408, then, from and after the record date for determining the holders of
     shares of Parent Common Stock entitled to receive the distribution, a
     Holder of a Security that converts such Security in accordance with the
     provisions of this Indenture shall upon such conversion be entitled to
     receive, in addition to the shares of shares of Parent Common Stock into
     which the Security is convertible, the kind and amount of securities, cash
     or other assets comprising the distribution that such Holder would have
     received if such Holder had converted the Security immediately prior to the
     record date for determining the holders of shares of Parent Common Stock
     entitled to receive the distribution.

     SECTION 1416.  Company Determination Final.

          Any determination that the Company, the Parent or the Board of
     Directors must make pursuant to Section 1405, 1406, 1407, 1408, 1409, 1410,
     1411, 1415 or 1417 is conclusive, absent manifest error.

     SECTION 1417.  Simultaneous Adjustments.

          In the event that this Article Fourteen requires adjustments to the
     Conversion Rate under more than one of Sections 1406(4), 1407, 1408 or
     1409, and the record dates for the distributions giving rise to such
     adjustments shall occur on the same date, then such adjustments shall be
     made by applying, first, the provisions of Section 1406(4), second, the
     provisions of Section 1408, third, the provisions of Section 1407, and
     fourth, the provisions of Section 1409.

     SECTION 1418.  Successive Adjustments.

          After an adjustment to the Conversion Rate under this Article
     Fourteen, any subsequent event requiring an adjustment under this Article
     Fourteen shall cause an adjustment to the Conversion Rate as so adjusted.

                                 ARTICLE THREE

                         [FORM OF REVERSE OF SECURITY]

                     Zero-Coupon Convertible Notes due 2021


1.  Cash Interest and Accretion Rate.

          Except as provided in this paragraph 1, this Security shall not bear
cash interest.  This Security shall initially represent the Issue Price and
shall accrete in value at an accretion rate of 3% per annum through the Stated
Maturity.

          Increased Accretion Rate. Beginning on May 15, 2004, if the Closing
Sales Price of the Parent Common Stock is equal to or less than 60% of the
Accreted Conversion Price of the Securities for any 20 trading days out of the
last 30 consecutive trading days ending three Business Days prior to such date
or three Business Days prior to any May 15 or November 15 thereafter, then the
accretion rate on the Securities for the semi-annual period commencing on such
date will be subject to an increased accretion rate equal to the applicable per
annum Reset Rate in effect at that time.  Any increased accretion rate made
pursuant to the preceding sentence will remain in effect until the May 15 or
November 15 thereafter when the Closing Sales Price of the Parent Common Stock
is not equal to or less than 60% of the Accreted Conversion Price of the
Securities for any 20 trading days out of the last 30 consecutive trading days
ending three Business Days prior to such date, at which time the accretion rate
will revert to 3% per annum.

          The "Reset Rate" will be established by the Reset Rate Agent, as of
each Reset Rate Determination Date. The "Reset Rate Determination Date" shall be
the date three Business Days preceding each of:

               (i) May 15, 2004, in which case the Reset Rate will be the Two-
     Year Reset Rate;

               (ii) May 15, 2006, in which case the Reset Rate will be the Five-
     Year Reset Rate;

               (iii)  May 15, 2008, in which case the Reset Rate will be the
     Two-Year Reset Rate;

               (iv) November 15, 2009, in which case the Reset Rate will be the
     One-Year Reset Rate;

               (v) May 15, 2011, in which case the Reset Rate will be the Five-
     Year Reset Rate;

                                      A-4
<PAGE>

               (vi) May 15, 2013, in which case the Reset Rate will be the Two-
     Year Reset Rate;

               (vii)  November 15, 2014, in which case the Reset Rate will be
     the One-Year Reset Rate;

               (viii)  May 15, 2016, in which case the Reset Rate will be the
     Five-Year Reset Rate;

               (ix) May 15, 2018, in which case the Reset Rate will be the Two-
     Year Reset Rate; and

               (x) November 15, 2019, in which case the Reset Rate will be the
     One-Year Reset Rate.

          The Reset Rate determined as of each Reset Rate Determination Date
will be equal to the rate that would, in the sole judgment of the Reset Rate
Agent, result in a trading price of par with a hypothetical issue of senior,
nonconvertible, noncontingent, fixed rate debt securities of the Company with
(i) a final maturity equal to, in the case of the Five-Year Reset Rate, five
years; in the case of the Two-Year Reset Rate, two years; and in the case of the
One-Year Reset Rate, one year; (ii) an aggregate principal amount equal to the
Accreted Principal Amount of the Securities; and (iii) covenants and other
provisions that are, insofar as would be practicable for an issue of senior,
nonconvertible, noncontingent, fixed rate debt securities, substantially
identical to those of the Securities. In no case, however, shall the Reset Rate
exceed 11% per annum or be less than 3% per annum.  If the Reset Rate Agent has
not established the Reset Rate for the applicable semi-annual period, or if the
Reset Rate Agent determines in its sole judgment that there is no suitable
reference rate from which the Reset Rate may be determined, the Reset Rate for
that period will be the Reset Rate most recently determined (except that if
there is no Reset Rate most recently determined, the Reset Rate shall be a rate
mutually agreed upon by the Reset Rate Agent and the Company reflecting current
market conditions), such Reset Rate to remain in effect until the Reset Rate
Agent determines that there is a suitable reference rate at which time the Reset
Rate Agent shall determine a new Reset Rate for the period ending on the next
Reset Rate Determination Date.

          The applicable per annum Reset Rate for a Security that is subject to
an increased accretion rate shall be determined as to any period for which such
increase is applicable as follows in each case until a new Reset Rate is in
effect:

               (i) effective May 15, 2004, the applicable per annum Reset Rate
     on such Security will be the Two-Year Reset Rate established on the Reset
     Rate Determination Date three Business Days preceding May 15, 2004;

               (ii) effective May 15, 2006, the applicable per annum Reset Rate
     on such Security will be the Five-Year Reset Rate established on the Reset
     Rate Determination Date three Business Days preceding May 15, 2006;

                                      A-5
<PAGE>

               (iii)  effective May 15, 2010 the applicable per annum Reset Rate
     on such Security will be the One-Year Reset Rate established on the Reset
     Rate Determination Date three Business Days preceding November 15, 2009;

               (iv) effective May 15, 2011 the applicable per annum Reset Rate
     on such Security will be the Five-Year Reset Rate established on the Reset
     Rate Determination Date three Business Days preceding May 15, 2011;

               (v) effective May 15, 2015, the applicable per annum Reset Rate
     on such Security will be the One-Year Reset Rate established on the Reset
     Rate Determination Date three Business Days preceding November 15, 2014;

               (vi) effective May 15, 2016, the applicable per annum Reset Rate
     on such Security will be the Five-Year Reset Rate established on the Reset
     Rate Determination Date three Business Days preceding May 15, 2016; and

               (vii)  effective May 15, 2020, the applicable per annum Reset
     Rate on such Security will be the One-Year Reset Rate established on the
     Reset Rate Determination Date three Business Days preceding November 15,
     2019.

          Notwithstanding the foregoing:

               (x) if a Security first becomes subject to an increased accretion
     rate (or first becomes subject to an increased accretion rate following a
     reversion of the accretion rate to 3%) on or after May 15, 2008, but not
     later than November 15, 2009, the initial Reset Rate will be the Two-Year
     Reset Rate established on the Reset Rate Determination Date three Business
     Days preceding May 15, 2008 and thereafter the applicable Reset Rate will
     be determined in accordance with the prior sentence;

               (y) if a Security first becomes subject to an increased accretion
     rate (or first becomes subject to an increased accretion rate following a
     reversion of the accretion rate to 3%) on or after May 15, 2013, but not
     later than November 15, 2014, the initial Reset Rate will be the Two-Year
     Reset Rate established on the Reset Rate Determination Date three Business
     Days preceding May 15, 2013 and thereafter the applicable Reset Rate will
     be determined in accordance with the prior sentence; and

               (z) if a Security first becomes subject to an increased accretion
     rate (or first becomes subject to an increased accretion rate following a
     reversion of the accretion rate to 3%) on or after May 15, 2018, but not
     later than November 15, 2019, the initial Reset Rate will be the Two-Year
     Reset Rate established on the Reset Rate Determination Date three Business
     Days preceding May 15, 2018 and thereafter the applicable Reset Rate will
     be determined in accordance with the prior sentence.

          If an increased accretion rate is in effect for a particular semi-
annual period, the Company will pay a portion of the increased accretion rate as
cash interest at an annualized rate of 0.25% per annum (or 0.125% per semi-
annual period) on the Applicable Principal Amount and the remaining increased

                                      A-6
<PAGE>

accretion rate will be accrued and payable at maturity, redemption or
repurchase.

          For the determination of the Reset Rate, the Reset Rate Agent shall
seek indicative reference rates from three nationally recognized investment
banks.  The determination of any Reset Rate will be conclusive and binding upon
the Reset Rate Agent, the Parent, the Company, the Trustee and the Holders, in
the absence of manifest error.

          The Reset Rate Agent may be removed at any time by the Parent giving
at least sixty days' written notice to the Reset Rate Agent. The Reset Rate
Agent may resign at any time upon giving at least thirty days' written notice.

          For purposes of this Paragraph 1, the following defined terms shall
have the respective meanings provided below.

          "Accreted Conversion Price" means, as of any date, the Accreted
Principal Amount of this Security divided by the Conversion Rate (as defined in
the Indenture).

          "Accreted Principal Amount" means, for any date, the Issue Price (as
defined in the Indenture) of the Securities adjusted to reflect the accretion of
the Securities at the applicable accretion rate to such date.

          "Applicable Principal Amount" means, for any semi-annual period, the
Issue Price of the Securities adjusted to reflect the accretion of the
Securities at the applicable accretion rate to the beginning of such semi-annual
period (excluding any accrued and unpaid cash interest).

          "Reset Rate Agent" means a nationally recognized financial institution
to be appointed by the Company to establish the applicable Reset Rate as of each
Reset Rate Determination Date.

          In the event of an increased accretion rate, the Company will
disseminate a press release through Reuters Economic Services or Bloomberg
Business News containing this information or publish the information on the
Parent's web site on the World Wide Web or through such other public medium as
the Parent may use at that time.

          Tax Event.  From and after the date of the occurrence of a Tax Event,
the Company will have the option to pay cash interest on the Securities instead
of accreting the principal amount thereof, including any cash interest payable
pursuant to an increased accretion rate.  Following the Company's election to
pay cash interest following a Tax Event, the principal amount on which cash
interest is payable will be restated and will equal the Restated Principal
Amount, and cash interest will accrue from the date of such restatement.  The
Restated Principal Amount shall be the amount due at maturity of the Securities.
Cash interest will be paid on the Restated Principal Amount at a rate equal to
the accretion rate that would be in effect from time to time if the Company had
not elected to pay cash interest.

                                      A-7
<PAGE>

          A "Tax Event" means that the Company shall have received an opinion
from a nationally-recognized independent tax counsel experienced in such matters
to the effect that, as a result of:

               (i) any amendment to, or change (including any announced
     prospective change (which will not include a proposed change)) in, the laws
     (or any regulations thereunder) of the United States or any political
     subdivision or taxing authority of the United States or any political
     subdivision, provided that a Tax Event will not occur more than 90 days
     before the effective date of any prospective change in such laws or
     regulations;

               (ii) any judicial decision or official administrative
     pronouncement, ruling, regulatory procedure, notice or announcement,
     including any notice or announcement of intent to adopt such procedures or
     regulations (an "Administrative Action''); or

               (iii)  any amendment to or change in the administrative position
     or interpretation of any Administrative Action or judicial decision that
     differs from the theretofore generally accepted position, in each case, by
     any legislative body, court, government agency or regulatory body,
     irrespective of the manner in which such amendment or change is made known,
     which amendment or change is effective or such Administrative Action or
     decision is announced, in each case, on or after the Issue Date;

there is more than an insubstantial risk that interest payable on this Security,
including amounts reflecting accretion of the Securities included in the
Accreted Principal Amount and any cash interest payable pursuant to an increased
accretion rate, either:

               (i) would not be deductible on a current accrual basis; or

               (ii) would not be deductible under any other method, in either
     case in whole or in part, by the Company for United States federal income
     tax purposes.

          Cash Interest and Accretion Computation and Method of Payment.  Any
cash interest payable hereunder and any accretion of the Securities will be
computed based on a 360-day year of twelve 30-day months.  Cash interest, if
any, will be payable semi-annually in arrears on each May 15 and November 15
(each an "Interest Payment Date") through maturity;  provided that, in the event
the Company elects to pay cash interest upon the occurrence of a Tax Event as of
a date less than 60 days prior to any Interest Payment Date, the first payment
of cash interest shall be made on the Interest Payment Date next succeeding such
Interest Payment Date.  The record date for the payment of cash interest to
Holders will be the close of business on May 1 and November 1 of each year
(whether or not a Business Day);  provided that cash interest payable at Stated
Maturity or upon redemption or repurchase will be payable to the person to whom
principal is payable.  The Company will give notice to the Holders, no later
than 15 days prior to each record date, of the amount of cash interest to be
paid as of the next Interest Payment Date.  Cash interest on the Securities will
be paid to registered holders of the Securities as of the record date.

2.   Method of Payment at Redemption, Repurchase or Maturity.

                                      A-8
<PAGE>

          Subject to the terms and conditions of the Indenture, the Company will
make payments (1) in cash in respect of a Redemption Price, Change in Control
Purchase Price and at Stated Maturity and (2) in cash, shares of Parent Common
Stock or a combination thereof in respect of a Purchase Price, in each case to
Holders who surrender Securities to a Paying Agent to collect such payments in
respect of the Securities. 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. However, the Company may pay such cash amounts by check
payable in such money.

3.   Paying Agent, Conversion Agent, Security Registrar and Reset Rate Agent.

          First Union National Bank (the "Trustee") will initially act as Paying
Agent, Conversion Agent and Security Registrar.  The Company may appoint and
change any Paying Agent, Conversion Agent, Security Registrar or Reset Rate
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, The
City of New York, The 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
Reset Rate Agent.

4.   Indenture.

          The Company issued the Securities under an Indenture dated as of
December 1, 2000, as amended (the "Indenture"), among the Company, the Parent
and the Trustee.  The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act.  The Securities are subject to all such terms, and Holders are
referred to the Indenture and the Trust Indenture Act for a statement of those
terms.  Capitalized terms used herein and not defined herein have the meanings
ascribed thereto in the Indenture.

          The Securities are general unsecured obligations of the Company
limited to $6,258,390,000 aggregate principal amount at maturity, subject to
upward adjustment from time to time in the event there is an increased accretion
rate in effect pursuant to paragraph 1 hereof.

          The Indenture does not limit other indebtedness of the Company,
secured or unsecured.

5.   Redemption at the Option of the Company.

          The Securities are redeemable at the option of the Company in whole or
in part, at any time or from time to time on, or after May 15, 2006 upon not
less than 30 nor more than 60 days' notice by mail to Holders for a cash price
equal to the Accreted Principal Amount plus any accrued and unpaid cash
interest, up to the Redemption Date (the "Redemption Price").  No sinking fund
is provided for the Securities.

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each Holder of Securities to be redeemed
at the Holder's registered address.

                                      A-9
<PAGE>

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 Securities held by such Holder on May 15, 2004, May 15, 2006, May
15, 2011 and May 15, 2016, in integral multiples of $1,000 principal amount at
maturity, at a Purchase Price equal to the Accreted Principal Amount plus any
accrued and unpaid cash interest to the Purchase Date or, if the Company has
previously exercised its option to pay cash interest instead of accreting the
principal amount of the Securities following a Tax Event, at a purchase price
equal to the Restated Principal Amount plus accrued and unpaid cash interest to
the Purchase Date.  To exercise such right, a Holder shall deliver to the
Company a Purchase Notice containing the information set forth in the Indenture,
at any time from the opening of business on the date that is 20 Business Days
prior to such Purchase Date until the close of business on the Business Day
prior to such Purchase Date, and shall deliver the Securities to the Paying
Agent as set forth in the Indenture.

          The Purchase Price may be paid, at the option of the Company, in cash
or by delivery of shares of Parent Common Stock, or in any combination thereof.
If the Company elects to pay the Purchase Price in shares of Parent Common Stock
or a combination of Parent Common Stock and cash, the Company shall notify
Holders of such election 20 Business Days prior to the Purchase Date.

          Subject to the terms and conditions of the Indenture, if a Change in
Control occurs, the Company shall become obligated to purchase, at the option of
the Holder, all or any portion of the Securities held by such Holder, at a
purchase price equal to the Accreted Principal Amount plus any accrued and
unpaid cash interest to the Change in Control Purchase Date or, if the Company
has previously exercised its option to pay cash interest instead of accreting
the principal amount of the Securities following a Tax Event, at a purchase
price equal to the Restated Principal Amount plus any accrued and unpaid cash
interest to the Change in Control Purchase Date.  To exercise such right, a
Holder shall deliver to the Company a Change in Control Purchase Notice
containing the information set forth in the Indenture, at any time until the
close of business on the 30th day after the date the Company delivers its
written notice of the occurrence of a Change in Control, and shall deliver the
Securities to the Paying Agent as set forth in the Indenture.

          Holders have the right to withdraw any Purchase Notice or Change in
Control 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 Parent Common Stock if permitted under the Indenture)
sufficient to pay the Purchase Price or Change in Control Purchase Price, as the
case may be, of all Securities or portions thereof to be purchased as of the
Purchase Date or the Change in Control Purchase Date, as the case may be, is
deposited with the Paying Agent on the fifth Business Day following the Purchase
Date or prior to 10:00 a.m. (local time in the City of New York) on the Change
in Control Purchase Date and cash interest ceases to accrue on such Securities
(or portions thereof) and the Securities cease to accrete in value immediately
after such Purchase Date or Change in Control Purchase Date, the Holder thereof
shall have no other rights as such other than the right to receive the Purchase

                                     A-10
<PAGE>

Price or Change in Control Purchase Price upon surrender of such Security.

7.   Conversion.

          Holders may surrender Securities for conversion into shares of Parent
Common during any quarterly conversion period if the Closing Sales Price of the
Parent Common Stock for at least 20 trading days in the 30 consecutive trading
days ending on the first day of the quarterly conversion period is more than the
percentage which shall initially be 120% and shall decline by .25% per semi-
annual period over the life of the Securities to 110% (the "Applicable
Percentage") of the Accreted Conversion Price on the first day of such quarterly
conversion period.  A "quarterly conversion period" will be the period from and
including the 12th trading day in a fiscal quarter of the Parent to but not
including the 12th trading day in the immediately following fiscal quarter of
the Parent.

          Holders may also surrender Securities for conversion into shares of
Parent Common Stock during the five Business Day period following the ten
Business Days after any nine consecutive trading day period in which for each
day the trading price of the Securities (as determined by the Trustee) is less
than 95% of the product of the Closing Sales Price of the Parent Common Stock
multiplied by the number of shares into which a Security is convertible for that
period.  The "trading price" of the Securities on any date of determination
means the average of the secondary market bid quotations per Security obtained
by the Conversion Agent for $10,000,000 principal amount at maturity of the
Securities at approximately 3:30 p.m., New York City time, on such determination
date from three independent nationally recognized securities dealers selected by
the Company; provided that if at least three such bids cannot reasonably be
obtained by the Conversion Agent, but two such bids are obtained, then the
average of the two bids shall be used, and if only one such bid can reasonably
be obtained by the Conversion Agent, this one bid shall be used; and provided
further that if there are different secondary market quotations for Securities
that have been resold in transactions registered under any registration
statement filed with the Commission (as defined in the Indenture) and Securities
that have been resold pursuant to the exemption from registration under the
Securities Act provided by Rule 144 thereunder, the "trading price" of the
Securities will be determined based on the higher of the two sets of market
quotations.  If the Conversion Agent cannot reasonably obtain at least one bid
for $10,000,000 principal amount of maturity of the Securities from a nationally
recognized securities dealer or, in the reasonable judgment of the Company, the
bid quotations are not indicative of the secondary market value of the
Securities, then the trading price of the Securities will equal (a) the then-
applicable Conversion Rate of the Securities multiplied by (b) the closing price
on the New York Stock Exchange of Parent Common Stock on such determination
date.

          For the purposes of the immediately preceding paragraph, the term
"nine consecutive trading day period" means any nine consecutive trading days
during which the Conversion Agent determines the trading price of the
Securities; provided that the Conversion Agent shall have no obligation to
determine the trading price of the Securities unless requested by the Company;
and provided further that the Company shall have no obligation to make such
request unless a Holder provides the Company with reasonable evidence that the
trading price of the Securities would be less than 95% of the product of the
Closing Sales Price of the Parent Common Stock multiplied by the number of

                                     A-11
<PAGE>

shares into which a Security is convertible; and at which time, the Company
shall instruct the Conversion Agent to determine the trading price of the
Securities beginning on the next trading day and on each successive trading day
until the trading price is greater than or equal to 95% of the product of the
Closing Sales Price of the Parent Common Stock and the number of shares into
which a Security is convertible.

          If at the time of conversion pursuant to the second paragraph of this
Paragraph 7 the Closing Sales Price of Parent Common Stock is greater than 100%
of the Accreted Conversion Price but equal to or less than the Applicable
Percentage of the Accreted Conversion Price, then the Holders will receive, in
lieu of shares of Parent Common Stock based on the applicable Conversion Rate,
at the Company's option, cash or shares of Parent Common Stock, or a combination
of both cash and shares, with a value equal to the Accreted Principal Amount of
the Securities on the Conversion Date ("Accreted Value Conversion").  If there
is an Accreted Value Conversion, the shares of Parent Common Stock will be
valued at the average Closing Sales Price for the five trading days ending on
the third trading day prior to the date of conversion.  If the Company elects to
pay all or a portion of the Accreted Principal Amount upon an Accreted Value
Conversion in shares of Parent Common Stock, the Company will notify holders not
less than nine trading days prior to the beginning of the five Business Day
period in which Holders can convert their Securities pursuant to an Accreted
Value Conversion.

          A Holder may also surrender for conversion a Security or portion of a
Security which has been called for redemption pursuant to Paragraph 5 hereof,
even if the foregoing provisions have not been satisfied.  Such Securities may
be surrendered for conversion at any time following receipt of a notice of
redemption until the close of business on the Business Day prior to the
Redemption Date.

          In the event that the Parent distributes to all holders of Parent
Common Stock certain rights, for a period expiring within 60 days, as described
in Section 1407 of the Indenture, or a dividend or a distribution, as described
in Section 1408 of the Indenture where the fair market value of such dividend or
distribution per share of Parent Common Stock, as determined in the Indenture,
exceeds 15% of the Closing Sales Price of a share of Parent Common Stock as of
the trading day prior to the date of declaration for such distribution, the
Securities may be surrendered for conversion beginning on the date the Company
gives notice to the Holders of such right, which shall be not less than 20 days
prior to the Ex-Dividend Time for such dividend or distribution, and at any time
thereafter until the close of business on the Business Day prior to the Ex-
Dividend Time or until the Company announces that such distribution will not
take place.  No adjustment to the ability of a Holder to convert will be made if
such Holder will otherwise participate in the dividend or distribution without
conversion.

          In addition, in the event the Parent is a party to a consolidation,
merger or binding share exchange pursuant to which the shares of Parent Common
Stock would be converted into cash, securities or other property as set forth in
Section 1415 of the Indenture, the Securities may be surrendered for conversion
at any time from and after the date which is 15 days prior to the date the
Parent announces as the anticipated effective time until 15 days after the
actual date of such transaction.

                                     A-12
<PAGE>

          If the Parent is a party to a consolidation, merger or binding share
exchange pursuant to which the Parent Common Stock is converted into cash,
securities or other property, at the effective time of the transaction, the
right to convert a Security into shares of Parent Common Stock will be changed
into a right to convert it into the kind and amount of cash, securities or other
property which the Holder would have received if the Holder had converted its
Securities immediately prior to the transaction.

          A Security in respect of which a Holder has delivered a Purchase
Notice or a Change in Control Purchase Notice exercising the option of such
Holder to require the Company to purchase such Security may be converted only if
such notice of exercise is withdrawn in accordance with the terms of the
Indenture.

          The Conversion Rate is 7.9318 shares of Parent Common Stock per $1,000
principal amount at maturity, subject to adjustment in certain events described
in the Indenture. A Holder which surrenders Securities for conversion will
receive cash in lieu of any fractional share of Parent Common Stock.

          To surrender a Security for conversion, a Holder must (1) complete and
manually sign the irrevocable conversion notice below (or complete and manually
sign a facsimile of such notice) and deliver such notice to the Conversion
Agent, (2) furnish appropriate endorsements and transfer documents and (3) pay
any transfer or similar tax, if required.

          A Holder may convert a portion of a Security if the principal amount
at maturity of such portion is $1,000 at maturity or an integral multiple of
$1,000 at maturity, subject to an upward adjustment in the event there is an
increased accretion rate.   No payment or adjustment will be made for dividends
on the shares of Parent Common Stock except as provided in the Indenture. Except
as provided herein and in the Indenture, on conversion of a Security, the Holder
will not receive any cash payment representing the Accreted Principal Amount
with respect to the converted Securities. Instead, upon conversion the Company
will deliver to the Holder a fixed number of shares of Parent Common Stock and
any cash payment to account for fractional shares.  The cash payment for
fractional shares will be based on the Closing Sales Price of the Parent Common
Stock on the trading day immediately prior to the Conversion Date.  Delivery of
shares of Parent Common Stock will be deemed to satisfy the Company's obligation
to pay the principal amount of the Securities, including accrued cash interest.
Accrued cash interest will be deemed paid in full rather than canceled,
extinguished or forfeited.  The Company will not adjust the Conversion Rate to
account for accrued interest.

          The Conversion Rate will be adjusted as provided in Article Fourteen
of the Indenture. The Company may increase the Conversion Rate for at least 20
days, so long as the increase is irrevocable during such period.

8.   Denominations; Transfer; Exchange.

          The Securities 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 Securities 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

                                     A-13
<PAGE>

fees required by law or permitted by the Indenture. The Security Registrar need
not transfer or exchange any Securities selected for redemption (except, in the
case of a Security to be redeemed in part, the portion of the Security not to be
redeemed) or any Securities in respect of which a Purchase Notice or Change in
Control Purchase Notice has been given and not withdrawn (except, in the case of
a Security to be purchased in part, the portion of the Security not to be
purchased) or any Securities for a period of 15 days before the mailing of a
notice of redemption of Securities to be redeemed.

9.   Persons Deemed Owners.

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

10.  Unclaimed Money or Securities.

          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 Securities 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 only to the Company for
payment as general creditors unless an applicable abandoned property law
designates another person.

11.  Amendment; Waiver.

          The Company, the Parent and the Trustee, with the written consent of
the Holders of at least a majority in aggregate principal amount of the
Securities at the time outstanding, may amend the Indenture or the Securities.
However, without the consent of each Holder affected, an amendment or supplement
to the Indenture or the Securities may not:

          (1) reduce the principal of or premium on or change the Stated
     Maturity of any Security;

          (2) reduce the rate of or change the time for payment of cash interest
     on, or reduce the accretion rate of, any Security;

          (3) reduce or alter the method of computation of the Redemption Price,
     Purchase Price or Change in Control Purchase Price of any Security or the
     time when such Redemption Price, Purchase Price or Change in Control
     Purchase Price is payable;

          (4) make the principal of, or cash interest on, any Security payable
     in money or securities other than that stated in the Security or change the
     price of payment;

          (5) make any change that would impair any of the rights granted in
     Section 508 of the Indenture in any material respect;

          (6) modify any provisions of the Support Agreement or the Share
     Contribution Agreement, except for such modifications which do not
     adversely affect the interests of Holders in any material respect; or

                                     A-14
<PAGE>

          (7) reduce the percentage of principal amount of the outstanding
     Securities of a series required to amend or supplement the Indenture or
     waive any of its provisions.

          It shall not be necessary for the consent of the Holders under this
paragraph 11 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 paragraph 11 becomes effective, the
Trustee will mail to each Holder a notice briefly describing such amendment.

12.  Defaults and Remedies.

          Under the Indenture, Events of Default include:

               (1) the Company's failure for 90 days to pay when due any cash
     interest

               on the Securities (after any increased accretion rate or after
     the Company's election to pay cash interest on the Securities following a
     Tax Event);

               (2) the Company's failure to pay principal on the Securities (or,
     if the Company has elected to pay cash interest on the Securities following
     a Tax Event, the Restated Principal Amount) when due, whether at Stated
     Maturity, by declaration, upon redemption, upon repurchase or otherwise;

               (3) the Company's failure to perform, or breach of, any covenant
     or warranty in the Securities or in the Indenture and applicable to the
     Securities for 90 days after notice to the Company by the Trustee or by
     Holders of at least 25% in principal amount at maturity of the outstanding
     Securities; and

               (4) certain events involving bankruptcy, insolvency or
     reorganization of the Parent or the Company.

          Holders may not enforce the Indenture or the Securities except as
provided in the Indenture.  The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security.  Subject to
certain limitations, Holders of a majority in aggregate principal amount of the
Securities at the time outstanding may direct the Trustee in its exercise of any
trust or power.  The Trustee may withhold from Holders notice of any continuing
default under the Indenture (except a default in payment of amounts specified in
clauses (1) or (2) above) if it determines that withholding notice is in their
interests; and provided, further, that in the case of any default of the
character specified in clause (3) above no such notice to Holders shall be given
until at least 60 days after the occurrence thereof.

13.  Trustee Dealings with the Company.

          Subject to certain limitations imposed by the Trust Indenture Act, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal

                                     A-15
<PAGE>

with the Company or its Affiliates with the
same rights it would have if it were not Trustee.

14.  No Recourse Against Others.

          A director, officer, employee or shareholder, as such, of either the
Company or the Parent shall not have any liability for any obligations of the
Company under the Securities or the Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation.  By accepting a
Security, each Holder waives and releases all such liability. The waiver and
release are part of the consideration for the issue of the Securities.

15.  Authentication.

          This Security shall not be valid until an authorize signatory of the
Trustee manually signs the Trustee's Certificate of Authentication on the other
side of this Security.

16.  Abbreviations.

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

17.  GOVERNING LAW.

          THE LAWS OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE AND THIS
SECURITY.

18.  Registration Rights.

          The Holders of the Securities are entitled to the benefits of a
Registration Rights Agreement, dated as of May 15, 2001, among Company and
Goldman, Sachs & Co. and Credit Suisse First Boston Corporation, including the
receipt of liquidated damages upon a registration default (as defined in such
agreement).
