                                   SCHEDULE A

      Section 4.02. Purchase at Option of the Holder upon a Fundamental Change.

      (a)   If a Fundamental Change shall occur at any time prior to July 20,
2002, each Holder of Notes shall have the right, at such Holder's option, to
require the Company to purchase such Holder's Notes on the date (the
"Fundamental Change Purchase Date") (or if such date is not a Business Day, the
next succeeding Business Day) that is 95 days after the date of the Fundamental
Change. The Notes shall be purchased in integral multiples of $1,000 of
Principal Amount. The Company shall purchase such Notes for Cash at a price (the
"Fundamental Change Purchase Price") equal to the Accreted Value on the
Fundamental Change Purchase Date. No Notes may be purchased at the option of the
Holders due to a Fundamental Change if there has occurred and is continuing an
Event of Default other than an Event of Default that is cured by the payment of
the Purchase Price of all such Notes.

      (b)   The Company, or at its request (which must be received by the
Trustee at least three Business Days (or such lesser period as agreed to by the
Trustee) prior to the date the Trustee is requested to give such Notice as
described below) the Trustee in the name of and at the expense of the Company,
shall mail to all Holders of record of the Notes a Notice (a "Fundamental Change
Purchase Notice") of the occurrence of a Fundamental Change and of the purchase
right arising as a result thereof, including the information required by Section
4.03(e), on or before the 30th day after the occurrence of such Fundamental
Change. The Company shall promptly furnish to the Trustee a copy of such Notice.

      (c)   For a Note to be so purchased at the option of the Holder, the
Paying Agent must receive such Note with the form entitled "Fundamental Change
Purchase Notice" on the reverse thereof duly completed, together with such Note
duly endorsed for transfer, on or before the 60th day after the Fundamental
Change Purchase Notice is delivered; provided, however, if the Notes are in
book-entry form such transfer shall be made in accordance with the customary
practices of the depository. All questions as to the validity, eligibility
(including time of receipt) and acceptance of any Note for redemption shall be
determined by the Company, whose determination shall be final and binding.

      Section 4.03. Purchase of Notes at the Option of the Holder.

      (a)   Purchase of Notes at the Option of the Holder. On each of July 20,

20, 2016, July 20, 2021 and July 20, 2026 (each, a "Purchase Date"), at the
purchase price specified in paragraph 7 of the Notes (each, a "Purchase Price"),
a Holder of Notes shall have the option to require the Company to purchase any
outstanding Notes, upon:

            (i)   delivery to the Paying Agent by the Holder of a written Notice
      of purchase (a "Purchase Notice") at any time from the opening of business
      on the date that is 30 Business Days prior to a Purchase Date until the
      close of business on such Purchase Date, stating:

                  (A)   if certificated, the certificate numbers of the Notes
            which the Holder shall deliver to be purchased;

                                      A-1


                  (B)   the portion of the Principal Amount of the Notes which
            the Holder shall deliver to be purchased, which portion must be
            $1,000 in Principal Amount or a multiple thereof; and

                  (C)   that such Notes shall be purchased as of the Purchase
            Date pursuant to the terms and conditions specified in paragraph 7
            of the Notes and in this Supplemental Indenture.

            (ii)  delivery or book-entry transfer of such Note 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 or
      transfer 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 4.03 only if the Note so delivered or transferred
      to the Paying Agent shall conform in all respects to the description
      thereof in the related Purchase Notice.

      (b)   Procedures. The Company shall purchase from the Holder thereof,
pursuant to this Section 4.03, a portion of a Note if the Principal Amount of
such portion is $1,000 or a multiple of $1,000 if so requested by the Holder.
Provisions of this Supplemental Indenture that apply to the purchase of all of a
Note also apply to the purchase of such portion of such Note.

      Any purchase by the Company contemplated pursuant to the provisions of
Section 4.02 or this Section 4.03 shall be consummated by the delivery of Cash
(together with accrued and unpaid contingent interest, if any) promptly
following the later of the Purchase Date and the time of delivery or book-entry
transfer of the Note.

      Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent the Purchase Notice or Fundamental Change Purchase Notice
contemplated by Section 4.02 or Section 4.03(a) shall have the right at any time
prior to the close of business on the Purchase Date or Fundamental Change
Purchase Date to withdraw such Purchase Notice or Fundamental Change Purchase
Notice (in whole or in part) by delivery of a written notice of withdrawal to
the Paying Agent in accordance with Section 4.04(a).

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

      (c)   Delivery of Officers' Certificate. At least five Business Days
before the Company Notice Date, the Company shall deliver an Officers'

      Notice required by Section 4.03(e).

      (d)   Purchase with Cash. The Purchase Price or Fundamental Change
Purchase Price of Notes in respect of which a Purchase Notice or Fundamental
Change Purchase Notice pursuant to Section 4.02 or Section 4.03(a) has been

"Company Notice Date") or on or before the 30th day after the occurrence of the
Fundamental Change, as the case may be. Such Company Notice shall state that
payments shall be made in Cash and shall include a form of Purchase Notice or
Fundamental Change Repurchase Notice to be completed by a Holder and shall
state:

            (i)   the Purchase Price, the Fundamental Change Purchase Price, the
      Conversion Rate and, to the extent known at the time of such Notice, the
      amount of contingent interest, if any, that will be payable with respect
      to the Notes on the Purchase Date;

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

            (iii) that Notes as to which a Purchase Notice or Fundamental Change
      Purchase Notice has been given may be converted only if the applicable
      Purchase Notice has been withdrawn in accordance with the terms of this
      Supplemental Indenture;

            (iv)  that Notes must be surrendered to the Paying Agent to collect
      payment of the Purchase Price or Fundamental Change Purchase Price and

            (v)   that the Purchase Price or Fundamental Change Purchase Price
      for any Note as to which a Purchase Notice has been given and not
      withdrawn, together with any accrued contingent interest payable with
      respect thereto, shall be paid promptly following the later of the

            (vi)  the procedures the Holder must follow under Section 4.02 and
      Section 4.03;

            (vii) briefly, the conversion rights of the Notes;

      Purchase Price or Fundamental Change Purchase Price and contingent
      interest, if any, Accreted Value and interest (including contingent
      interest), if any, on Notes covered by any Purchase Notice or Fundamental
      Change Purchase Notice (or interest, if the Notes have been converted into

give the Company Notice in the Company's name; provided, however, that, in all
cases, the text of the Company Notice shall be prepared by the Company.

      (e)   Covenants of the Company. All shares of Common Stock delivered upon
conversion of the Notes shall be newly issued shares or treasury shares, shall
be fully paid and nonassessable and shall be free from preemptive rights and
free of any lien or adverse claim.

      The Company shall cause to have listed or quoted all such shares of Common
Stock on each United States national securities exchange or over-the-counter or
other domestic market on which the Common Stock is then listed or quoted.

      (f)   Procedure upon Purchase. On or before 11:00 a.m. (New York City

Date), the Company shall deposit with the Paying Agent Cash sufficient to pay
the aggregate Purchase Price or Fundamental Change Purchase Price of, and any

Price or Fundamental Change Purchase Price of such Note on the Business Day
following the Purchase Date or Fundamental Change Purchase Date, then, on and
after such date, such Note shall cease to be outstanding and Accreted Value on
such Note shall cease to accrue, whether or not book-entry transfer of such Note

      Section 4.04. Further Conditions for Purchase at the Option of Holders

      (a)   Effect of Purchase Notice or Fundamental Change Purchase Notice.
Upon receipt by the Company of the Purchase Notice or Fundamental Change
Purchase Notice specified in Section 4.03(a) or Section 4.02(c), as applicable,
the Holder of the Note in respect of which such Purchase Notice or Fundamental
Change Purchase Notice, as the case may be, was given shall (unless such
Purchase Notice or Fundamental Change Purchase Notice is withdrawn as specified
in the following two paragraphs) thereafter be entitled to receive solely the
Purchase Price or Fundamental Change Purchase Price, as the case may be, and any
accrued and unpaid contingent interest, if any, with respect to such Note. Such
Purchase Price or Fundamental Change Purchase Price and contingent interest, if
any, shall be paid to such Holder promptly following the later of (x) the
Purchase Date or the Fundamental Change Purchase Date, as the case may be, with
respect to such Note (provided the conditions in Section 4.03(a) or Section
4.02(c), as applicable, have been satisfied) and (y) the time of delivery or
book-entry transfer of such Note to the Paying Agent by the Holder thereof in
the manner required by Section 4.03(a) or Section 4.02(c), as applicable. Notes
in respect of which a Purchase Notice or Fundamental Change Purchase Notice, as
the case may be, has been given by the Holder thereof may not be converted

                                      A-4


for shares of Common Stock on or after the date of the delivery of such Purchase
Notice (or Fundamental Change Purchase Notice, as the case may be), unless such
Purchase Notice (or Fundamental Change Purchase Notice, as the case may be) has
first been validly withdrawn as specified in the following two paragraphs.

      A Purchase Notice or Fundamental Change Purchase Notice, as the case may
be, may be withdrawn by means of a written notice of withdrawal delivered to the
office of the Paying Agent at any time prior to the close of business on the
Purchase Date or the Fundamental Change Purchase Date, as the case may be, to
which it relates specifying:

            (i)   if certificated, the certificate number of the Notes in
      respect of which such notice of withdrawal is being submitted;

            (ii)  the Principal Amount of the Notes with respect to which such
      notice of withdrawal is being submitted; and

            (iii) the Principal Amount, if any, of the Notes which remain
      subject to the original Purchase Notice or Company Fundamental Change
      Notice, as the case may be, and which has been or shall be delivered for
      purchase by the Company.

      A written notice of withdrawal of a Purchase Notice or Fundamental Change
Purchase Notice may be in the form of a conditional withdrawal containing the
information set forth in the preceding paragraph and contained in a written
notice of withdrawal delivered to the Paying Agent as set forth in the preceding
paragraph.

      There shall be no purchase of any Notes pursuant to Section 4.02 or
Section 4.03 or redemption pursuant to Section 4.01 if there has occurred prior
to, on or after, as the case may be, the giving, by the Holders of such Notes,
of the required Purchase Notice or Fundamental Change Purchase Notice, as the
case may be, or the giving by the Company of the required Redemption Notice, and
is continuing an Event of Default (other than an Event of Default that is cured
by the payment of the Purchase Price or Fundamental Change Purchase Price, as
the case may be, and any accrued and unpaid contingent interest with respect to
all such Notes). The Paying Agent will promptly return to the respective Holders
thereof any Notes (x) with respect to which a Purchase Notice or Fundamental
Change Purchase Notice, as the case may be, has been withdrawn in compliance
with this Supplemental Indenture, or (y) held by it during the continuance of an
Event of Default (other than an Event of Default that is cured by the payment of
the Purchase Price or Fundamental Change Purchase Price, as the case may be, and
any accrued and unpaid contingent interest with respect to all such Notes) in
which case, upon such return, the Purchase Notice or Fundamental Change Purchase
Notice with respect thereto shall be deemed to have been withdrawn.

      (b)   Notes Purchased in Part. Any Note that 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 Note, without service charge, a new Note or Notes, of any
authorized

                                      A-5


denomination as requested by such Holder in aggregate Principal Amount equal to,
and in exchange for, the portion of the Principal Amount of the Note so
surrendered which is not purchased or redeemed.

      (c)   Covenant to Comply with Securities Laws upon Purchase of Notes. In
connection with any offer to purchase Notes under Section 4.02 or 4.03, the
Company shall (i) comply with Rules 13e-4 and 14e-1 (which terms, as used
herein, include any successor provision thereto) under the Exchange Act, if
applicable; (ii) file the related Schedule TO (or any successor schedule, form
or report) under the Exchange Act, if applicable; and (iii) otherwise comply
with all federal and state securities laws so as to permit the rights and
obligations under Sections 4.02 and 4.03 to be exercised in the time and in the
manner specified in Sections 4.02 and 4.03.

      (d)   Repayment to the Company. The Trustee and the Paying Agent shall
return to the Company any Cash remains unclaimed as provided in paragraph 14 of
the Notes, together with interest that the Trustee has agreed to pay on the Cash
held by them for the payment of a Purchase Price or Fundamental Change Purchase
Price, as the case may be, or contingent interest, if any; provided, however,
that to the extent that the aggregate amount of Cash deposited by the Company
pursuant to Section 4.04(b) exceeds the aggregate Purchase Price or Fundamental
Change Purchase Price, as the case may be, of, and any accrued and unpaid
contingent interest with respect to, the Notes or portions thereof which the
Company is obligated to purchase as of the Purchase Date or Fundamental Change
Purchase Date, as the case may be, then promptly after the Business Day
following the Purchase Date or Fundamental Change Purchase Date, as the case may
be, the Trustee and the Paying Agent shall return any such excess to the Company
together with interest that the Trustee has agreed to pay, if any, while such
Cash is held by the Trustee or the Paying Agent.

                                      A-6

      In addition to the Purchase Price payable with respect to all Notes or

contingent interest, if any, with respect thereto, which contingent interest
shall be paid in Cash promptly following the later of the Purchase Date and the
time of delivery of such Notes to the Paying Agent pursuant to the Indenture.

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

      If Cash sufficient to pay a Fundamental Change Purchase Price or Cash
sufficient to pay a Purchase Price (together with any accrued and unpaid
contingent interest), with respect to all Notes or portions thereof to be
purchased as of the Purchase Date or the Fundamental Change Purchase Date, as
the case may be, is deposited with the Paying Agent on the Business Day
immediately following the Purchase Date or the Fundamental Change Purchase Date,
as the case may be, such Notes will cease to accrete and interest (including,
where applicable, contingent interest), if any, will cease to accrue on such
Notes (or portions thereof) on and after such date, and the Holder thereof shall
have no other rights as such (other than the right to receive the Purchase Price
or Fundamental Change Purchase Price, as the case may be, and, where applicable,
accrued and unpaid contingent interest, if any, upon surrender or such Note).
