                           FORM AND TERMS OF THE NOTES

SECTION 2.01 Form Generally.

                  The Notes and the Trustee's certificate of authentication
shall be substantially in the forms of Exhibits A-1 and A-2 attached hereto,
which are a part of this Indenture. The Notes may have notations, legends or
endorsements required by law, stock exchange rule or usage. The Company shall
provide any such notations, legends or endorsements to the Trustee in writing.
Each Note shall be dated the date of its authentication. The Notes shall be
issued only in registered form without coupons and only in denominations of
$1,000 Principal Amount at Maturity and any integral multiple thereof.

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

                                       10
<PAGE>

                  (a) Global Notes. The Notes shall be issued initially in the
form of one or more fully registered global notes (the "Global Notes")
substantially in the form of Exhibit A-1 attached hereto, which shall be
deposited on behalf of the purchasers of the Notes represented thereby with The
Depository Trust Company, New York, New York (the "Depository") and registered
in the name of Cede & Co., the Depository's nominee, duly executed by the
Company, authenticated by the Trustee. The aggregate Principal Amount at
Maturity of Outstanding Notes may from time to time be increased or decreased by
adjustments made on the records of the Trustee and the Depository or its nominee
as hereinafter provided.

                  The Global Notes may not be transferred except by the
Depository, in whole or in part, to another nominee of the Depository or to a
successor of the Depository or its nominee. If at any time (i) the Depository
notifies the Company that the Depository is unwilling or unable to continue as
Depository for the Global Notes or if at any time the Depository ceases to be a
clearing agency registered under the Exchange Act and a successor Depository for
the Global Notes is not appointed by the Company within 90 days after delivery
of such notice, (ii) the Company in its sole discretion decides to discontinue
use of the system of book-entry transfer through the Depository (or any
successor of the Depository) or (iii) there shall have occurred and be
continuing an Event of Default with respect to the Notes under the Indenture,
then the Company shall execute, and the Trustee shall, upon receipt of a Company
Order for authentication, authenticate and deliver, definitive Notes in an
aggregate principal amount equal to the Principal Amount at Maturity of such
Global Notes.

                  (b) Book-Entry Provisions. This Section 2.01(b) shall apply
only to the Global Notes deposited with or on behalf of the Depository.

                  The Company shall execute and the Trustee shall, in accordance
with this Section 2.01(b), authenticate and deliver the Global Notes that shall
be registered in the name of the Depository or the nominee of the Depository and
shall be delivered by the Trustee to the Depository or pursuant to the
Depository's written instructions.

                  Depository participants shall have no rights either under this
Indenture or with respect to any Global Notes held on their behalf by the
Depository or under such Global Notes. The Depository shall be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the record
owner of such Global Note for all purposes under this Indenture. Notwithstanding
the foregoing, nothing herein shall prevent the Company or the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depository or impair, as between the Depository and the
Depository participants, the operation of customary practices of such Depository
governing the exercise of the rights of an owner of a beneficial interest in the
Global Notes.

                  (c) Definitive Notes. Notes issued in certificated form shall
be substantially in the form of Exhibit A-2 attached hereto, but without
including the text referred to therein as applying only to Global Notes. Except
as provided above in subsection (a), owners of beneficial interests in the
Global Notes will not be entitled to receive physical delivery of definitive
Notes.

                  (d) Transfer and Exchange of the Notes. The transfer and
exchange of beneficial interests in the Global Notes shall be effected through
the Depository, in accordance with this

                                       11
<PAGE>

Indenture and the procedures of the Depository. Beneficial interests in the
Global Notes may be transferred to Persons who take delivery thereof in the form
of a beneficial interest in the Global Notes.

SECTION 2.02 Terms of the Notes.

                  THE FOLLOWING TERMS RELATING TO THE NOTES ARE HEREBY
ESTABLISHED:

                  (a) Title. The Notes shall constitute a series of Securities
having the title "Senior Subordinated Convertible Notes due 2034."

                  (b) Principal Amount. The aggregate Principal Amount at
Maturity of the Notes that may be authenticated and delivered under the
Indenture (except for Notes authenticated and delivered upon registration of,
transfer of, or in exchange for, or in lieu of, other Notes pursuant to Section
3.04, 3.05 or 3.06 of the Indenture) shall be $582,249,000.

                  (c) Stated Maturity. The entire outstanding Principal Amount
of Maturity at the Notes shall be due and payable, unless accelerated, redeemed
or required to be repurchased or converted pursuant to the Indenture, on January
15, 2034.

                  (d) Interest

                           (i)      The rate at which the Notes shall bear cash
                  interest shall be 1.4813% per annum on the Principal Amount at
                  Maturity of the Notes; the date from which interest shall
                  accrue on the Notes shall be December 29, 2003, or the most
                  recent Interest Payment Date to which cash interest has been
                  paid or provided for until January 15, 2009; the Interest
                  Payment Dates for cash interest for the Notes shall be January
                  15 and July 15 of each year, beginning July 15, 2004; the
                  interest so payable, and punctually paid or duly provided for,
                  on any Interest Payment Date, will be paid, in immediately
                  available funds, to the Persons in whose names the Notes (or
                  one or more Predecessor Securities) are registered at the
                  close of business on the Regular Record Date for such
                  interest, which shall be the December 31 or June 30, as the
                  case may be, next preceding such Interest Payment Date.
                  Interest shall be calculated on the basis of a 360-day year of
                  twelve 30-day months.

                           (ii)     Original Issue Discount, in the period
                  during which a Note remains Outstanding, shall accrue at 3.75%
                  per annum of the Issue Price plus any previously accrued
                  Original Issue Discount, beginning on January 15, 2009, on a
                  semiannual bond equivalent basis using a 360-day year of
                  twelve 30-day months.

                  (e) Contingent Interest

                           (i)      Contingent Cash Interest. The Company shall
                  make Contingent Cash Interest payments to the Holders during
                  any six-month period from January 16 and July 15 and from July
                  16 to January 15, beginning with the six-month period
                  commencing on January 16, 2009 (each, a "Semiannual Period")
                  if, but only if, the Average Security Market Price for the
                  five Trading Days ending on

                                       12
<PAGE>

                  the third Trading Day immediately preceding the first day of
                  the applicable Semiannual Period equals 120% or more of the
                  Relevant Value per Note. During any Semiannual Period when
                  Contingent Cash Interest is payable pursuant to this Section
                  2.02(e), each Contingent Cash Interest payment due and payable
                  on each $1,000 Principal Amount at Maturity of Notes for the
                  applicable Semiannual Period, shall equal the annual rate of
                  0.25% of the Average Security Market Price for the five
                  Trading Day measuring period referred to in the preceding
                  sentence. Contingent Cash Interest shall be calculated on the
                  basis of a 360-day year of twelve 30-day months.

                  As used in this Section 2.02(e), "Relevant Value" means the
                  sum of the Issue Price, accrued Original Issue Discount and
                  accrued cash interest, if any, on such Note to the day
                  immediately preceding the first day of the applicable
                  Semiannual Period. "Average Security Market Price" means, on
                  any date, the average of the secondary market bid quotations
                  per $1,000 Principal Amount at Maturity of Notes obtained by
                  the Bid Solicitation Agent for $2,500,000 Principal Amount at
                  Maturity of Notes at approximately 4:00 p.m., New York City
                  time, on such date from at least one independent nationally
                  recognized securities dealer (none of which shall be an
                  Affiliate of the Company) selected by the Company; provided,
                  however, that if (a) the Bid Solicitation Agent cannot
                  reasonably obtain at least one bid for $2,500,000 Principal
                  Amount at Maturity of Notes from a nationally recognized
                  securities dealer or (b) in the Company's reasonable judgment,
                  the bid quotations are not indicative of the secondary market
                  value of the Notes as of such date, then the Average Security
                  Market Price for such date shall equal the product of (i) the
                  Conversion Rate in effect as of such determination date
                  multiplied by (ii) the average Sale Price of the Common Stock
                  for the five Trading Days ending on such date, appropriately
                  adjusted, without duplication, to take into account the
                  occurrence, during the period commencing on the first of such
                  Trading Days during such five Trading Day period and ending on
                  such determination date, of any event described in Section
                  16.06. 16.07, 16.08, 16.09 or 16.10 hereof (subject to the
                  conditions set forth in Section 16.12 hereof).

                  The Original Issue Discount of the Notes will continue to
                  accrue whether or not Contingent Cash Interest payments are
                  made.

                           (ii)     Payment of Contingent Cash Interest;
                  Contingent Cash Interest Rights Preserved. If payable,
                  Contingent Cash Interest on a Note shall be paid to the Person
                  who is the Holder of that Note on the 15th day preceding the
                  last day of the applicable Semiannual Period (the "Contingent
                  Cash Interest Record Date"). Such payments shall be paid on
                  the last day of the Semiannual Period (in each case, a
                  "Contingent Cash Interest Payment Date"). Each payment of
                  Contingent Cash Interest on any Note shall be paid (A) if such
                  Note is held in the form of a Global Note, in the same-day
                  funds by transfer to an account maintained by the payee
                  located inside the United States, or (B) if such Note is held
                  in the form of a certificated Note, by check, mailed to the
                  address of such Holder as set forth in the Security Register.
                  In the case of a Global Note, interest payable on any
                  Contingent Cash Interest Payment Date will be paid to the

                                       13
<PAGE>

                  Depositary for the purpose of permitting the Depository to
                  credit the interest received by it in respect of such Global
                  Note to the accounts of the beneficial owners thereof.

                  Upon determination that Holders of Notes will be entitled to
                  receive Contingent Cash Interest during a Semiannual Period,
                  the Company will issue a press release and use its reasonable
                  best efforts to post such information on its website or
                  through such other public medium as the Company may use at the
                  time.

                  The Company may unilaterally increase the amount of interest
                  or Contingent Cash Interest it is required to pay but shall
                  have no obligation to do so.

SECTION 2.03 Calculations.

                  For the sole benefit of the Holders of the Notes, the
following Section 1.13 shall apply to the Notes:

                  Section 1.13 Calculations.

                  The calculation of the Purchase Price, Change in Control
Purchase Price, Conversion Rate, Sale Price of the Common Stock and each other
calculation to be made hereunder shall be the obligation of the Company. All
calculations made by the Company as contemplated pursuant to this Section 1.13
or otherwise pursuant to the Notes shall be final and binding on the Company and
the Holders absent manifest error. The Trustee, Paying Agent and Conversion
Agent shall not be obligated to recalculate, recompute or confirm any such
calculations.

SECTION 2.04 Application of Section 3.03 of the Indenture.

                  For the sole benefit of the Holders of the Notes, the words
"under its corporate seal reproduced thereon attested by its Secretary or one of

Registrars and herein sometimes collectively referred to as the "Security

the Company shall provide for the registration of Notes and for transfers of

The Company may have one or more co-registrars, one or more additional

                                       14

paying agents and one or more additional conversion agents. The term Paying

any additional conversion agent.

                  The Company shall enter into an appropriate agency agreement
with any Security Registrar or Co-Security Registrar, Paying Agent, Conversion
Agent or Bid Solicitation Agent (other than the Trustee). The agreement shall
implement the provisions of this Indenture that relate to such agent. The
Company shall notify the Trustee in writing of the name and address of any such
agent. If the Company fails to maintain a Security Registrar, Paying Agent,
Conversion Agent or when necessary a Bid Solicitation Agent, the Trustee shall
act as such and shall be entitled to appropriate compensation therefor pursuant
to Section 6.07 hereof. The Company or any Subsidiary or an Affiliate of either
of them may act as Paying Agent, Security Registrar, Conversion Agent or
Co-Security Registrar. None of the Company or any Subsidiary or any Affiliate of
the Company or any Subsidiary may act as Bid Solicitation Agent.

                  The Company initially appoints the Trustee as Security
Registrar, Conversion Agent and Paying Agent in connection with the Notes.

SECTION 2.06 Payment of Interest; Interest Rights Reserved.

                  For the sole benefit of the Holders of the Notes, Section 3.07
of the Base Indenture shall not apply and the following Section 3.07 shall apply
in its place:

                  SECTION 3.07 Payment of Interest; Interest Rights Reserved.

                  Cash or Contingent Cash Interest on any Note that is payable
in cash, and is punctually paid or duly provided for, on any applicable payment
date shall be paid to the Person in whose name that Note is registered at the
close of business on the Record Date for such interest at the office or agency
of the Company maintained for such purpose. Each installment of cash interest or
Contingent Cash Interest on any Note shall be paid in same-day funds by transfer
to an account maintained by the payee located inside the United States, if the
Trustee shall have received proper wire transfer instructions from such payee
not later than the related Record Date or, if no such instructions have been
received, by check mailed to the payee at its address set forth on the Security
Registrar's books. In the case of a permanent Global Note, cash interest or
Contingent Cash Interest payable on any applicable payment date will be paid to
the Depositary, with respect to that portion of such permanent Global Note held
for its account by Cede & Co. for the purpose of permitting such party to credit
the interest received by it in respect of such permanent Global Note to the
accounts of the beneficial owners thereof.

                  Except as otherwise specified with respect to the Notes, any
cash interest or Contingent Cash Interest on any Note that is payable, but is
not punctually paid or duly provided for, within 30 days following any
applicable payment date (herein called "Defaulted Interest," which term shall
include any accrued and unpaid interest that has accrued on such defaulted
amount in accordance with paragraph 1 of the Notes), shall be paid by the
Company, at its election in each case (x) to the Holder as of a Special Record
Date, as determined in accordance with clause (a) below, or (y) in the manner
set forth in clause (b) below:

                                       15
<PAGE>

                  (a) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Notes are registered at the close of
business on a Special Record Date (as defined herein) for the payment of such
Defaulted Interest, which shall be fixed in the following manner. The Company
shall notify the Trustee in writing of the amount of Defaulted Interest proposed
to be paid on each Note and the date of the proposed payment (which shall not be
less than 20 days after such notice is received by the Trustee), and at the same
time the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make arrangements satisfactory to the Trustee for such deposit on or prior
to the date of the proposed payment, such money when deposited to be held in
trust for the benefit of the Persons entitled to such Defaulted Interest as in
this clause (a) provided. Thereupon the Trustee shall fix a special record date
(the "Special Record Date") for the payment of such Defaulted Interest which
shall be not more than 15 days and not less than 10 days prior to the date of
the proposed payment and not less than 10 days after the receipt by the Trustee
of the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be mailed, first-class postage prepaid,
to each Holder of Notes at his address as it appears on the list of Holders
maintained pursuant to Section 3.05 hereof not less than 10 days prior to such
Special Record Date. Notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor having been mailed as aforesaid, such
Defaulted Interest shall be paid to the Persons in whose names the Notes are
registered at the close of business on such Special Record Date and shall no
longer be payable pursuant to the following clause (b) of this Section 3.07.

                  (b) The Company may make payment of any Defaulted Interest on
the Notes in any other lawful manner not inconsistent with the requirements of
any securities exchange on which such Notes may be listed, and upon such notice
as may be required by such exchange, if, after written notice given by the
Company to the Trustee of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee.

                  Subject to the foregoing provisions of this Section 3.07 and
Section 3.05 hereof, each Note delivered under this Indenture upon registration
of transfer of or in exchange for or in lieu of any other Note shall carry the
rights to cash and Contingent Cash Interest accrued and unpaid, and to accrue,
which were carried by such other Note.

cancellation or (b) all outstanding Notes have

                                       16

Affiliates) or the Conversion Agent cash or, if expressly permitted by the terms
of the Notes or the Indenture, Common Stock sufficient to pay all amounts due
and owing on all Outstanding Notes (other than Notes replaced pursuant to
Section 3.06 hereof), and if in either case the Company pays all other sums
payable hereunder by the Company, then this Indenture shall, upon a Company
Order, subject to Sections 6.03 and 6.07 hereof, which sections shall survive
such discharge, cease to be of further effect. The Trustee shall join in the
execution of a document prepared by the Company acknowledging satisfaction and
discharge of this Indenture on written demand of the Company accompanied by an
Officers' Certificate and Opinion of Counsel complying with Section 1.02 of the
Base Indenture and at the cost and expense of the Company.

                  SECTION 4.02 Repayment to the Company.

upon written request any money or securities held by them for the payment of any
amount with respect to the Notes that remains unclaimed for two years, subject
to applicable unclaimed property law. After return to the Company, Holders
entitled to the money or securities must look to the Company for payment as
general creditors unless an applicable abandoned property law designates another
person and the Trustee and the Paying Agent shall have no further liability to
the Holders with respect to such money or securities for that period commencing
after the return thereof.

days after receipt by the Company of a written notice from the Trustee;
provided, however, that if any such default specified in (i) or (ii) shall be

of Default by reason thereof shall be deemed not to have occurred; or

                  (e) the Company pursuant to or under or within the meaning of
any Bankruptcy Law:

                           (i) commences a voluntary case or proceeding;

SECTION 2.09 Acceleration of Maturity; Rescission and Annulment.

<PAGE>

                  SECTION 5.02. Acceleration of Maturity; Rescission and
Annulment.

                  If an Event of Default (other than an Event of Default
specified in Section 5.01(e) or (f) in respect of the Company) occurs and is
continuing, the Trustee by written notice to the Company, or the Holders of at
least 25% in aggregate Principal Amount at Maturity of the Notes at the time
outstanding by written notice to the Company and the Trustee, may declare the
Issue Price plus accrued Original Issue Discount and any accrued and unpaid cash
interest including Contingent Cash Interest, through the date of declaration on,
all the Notes to be immediately due and payable. Upon such a declaration, such
Issue Price plus accrued Original Issue Discount, and such accrued and unpaid
cash interest, if any, including Contingent Cash Interest, if any, shall be due
and payable immediately. If an Event of Default specified in Section 5.01(e) or
(f) occurs in respect of the Company and is continuing, the Issue Price plus
accrued Original Issue Discount and any accrued and unpaid cash interest,
including Contingent Cash Interest, on all the Notes shall become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders. The Holders of a majority in aggregate Principal
Amount at Maturity of the Outstanding Notes, by written notice to the Trustee
(and without notice to any other Holder) may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of the Issue Price plus accrued Original Issue Discount and any
accrued and unpaid cash interest, including Contingent Cash Interest, that have
become due solely as a result of acceleration and if all amounts due to the
Trustee under Section 6.07 hereof have been paid. No such rescission shall
affect any subsequent Default or impair any right consequent thereto.

SECTION 2.10 Unconditional Right of Holders to Receive Principal, Premium and
Interest.

                  For the sole benefit of the Holders of the Notes, Section 5.08

right of any Holder to receive payment of the Principal Amount at Maturity,
Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase
Price, Change in Control Purchase Price, or cash interest, including Contingent
Cash Interest, if any, in respect of the Notes held by such Holder, on or after
the respective due dates expressed in the Notes or any Redemption Date, and to
convert the Notes in accordance with Article XVI hereof, or to bring suit for
the enforcement of any such payment on or after such respective dates or the
right to convert, shall not be impaired or affected adversely without the

                  Subject to Section 5.02, the Holders of a majority in
aggregate Principal Amount at Maturity of the Outstanding Notes, by written
notice to the Trustee (and without notice to any other Holder), may on behalf of
the Holders of all of the Notes waive an existing Default and its consequences
except (a) an Event of Default described in Section 5.01(a) or (b), (b) a
Default in respect of a provision that under Section 9.02 cannot be amended
without the consent of each Holder affected or (c) a Default which constitutes a
failure to convert any Note in accordance with the terms of Article XVI. When a
Default is waived, such Default shall cease to exist and any Event of Default
arising therefrom shall be deemed cured for every purpose of the Indenture, but
no such waiver shall extend to any subsequent or other Default or impair any
consequent right. This Section 5.13 shall be in lieu of Section 316(a)1(B) of
the TIA and such Section 316(a)1(B) is hereby expressly excluded from this
Indenture, as permitted by the TIA.

SECTION 2.12 Notice of Defaults.

                  For the sole benefit of the Holders of the Notes, Section 6.02
of the Base Indenture shall not apply and the following Section 6.02 shall apply

hereunder with respect to the Notes, the Trustee shall transmit by mail to all
Holders of Notes, as their names and addresses appear in the Security Register,

case of a default in the payment of the principal of (or premium, if any) or
interest on any Note of such series or in the payment of any sinking fund
installment with respect to Notes of such series, the Trustee shall be protected
in withholding such notice if and so long as the board of directors, the
executive committee or a trust committee of directors or Responsible Officers of
the Trustee in good faith determine that the withholding of such notice is in
the interest of the Holders of Notes of such series.

any other person or convey, transfer or lease all or substantially all of its
properties and assets to any person, nor will the Company permit any Subsidiary
to enter into any such transaction or series of transactions (other than to the
Company or another Subsidiary) if such transaction or series of transactions, in

disposition of all or

                                       20
<PAGE>

                  (c) the Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger, conveyance, transfer or lease and, if a supplemental
indenture is required in connection with such transaction, such supplemental
indenture, comply with this Article VIII and that all conditions precedent
herein provided for relating to such transaction have been satisfied.

                  For purposes of the foregoing, the transfer (by lease,
assignment, sale or otherwise) of the properties and assets of one or more
Subsidiaries (other than to the Company or another Subsidiary), which, if such
assets were owned by the Company, would constitute all or substantially all of
the properties and assets of the Company, shall be deemed to be the transfer of
all or substantially all of the properties and assets of the Company.

                  The successor person formed by such consolidation or into
which the Company or the applicable Subsidiary is merged or the successor person
to which such conveyance, transfer or lease is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company or the

                  Section 11.01 Right to Redeem; Notices to Trustee.

                  The Company, at its option, may redeem the Notes in accordance
with the provisions of paragraphs 6 and 8 of the Notes. Prior to January 15,
2009, the Company may not redeem the Notes. Beginning on January 15, 2009, the
Company may redeem the Notes for cash in whole at any time, or in part from time
to time. If the Company elects to redeem Notes pursuant to paragraph 6 of the
Notes, it shall notify the Trustee in writing of the Redemption Date, the
Principal Amount at Maturity of Notes to be redeemed, the Redemption Price and
the amount of accrued and unpaid cash interest, if any, including Contingent
Cash Interest, if any, payable on the Redemption Date.

                  The Company shall give the notice to the Trustee provided for
in this Section 11.01 by a Company Order, at least 45 days before the Redemption
Date (unless a shorter notice shall be reasonably satisfactory to the Trustee).
If less than all the Outstanding Notes are to be redeemed, the record date
relating to such redemption shall be selected by the Company and given to the
Trustee, which record date shall not be less than ten days after the date of
notice to the Trustee (or such other period reasonably satisfactory to the
Trustee).

                  SECTION 11.02 Selection of Notes to Be Redeemed.

                  If less than all the Outstanding Notes are to be redeemed, the
Trustee shall select the Notes to be redeemed pro rata or by lot or by any other
method the Trustee considers fair and appropriate (so long as such method is not
prohibited by the rules of any securities exchange on which the Notes are then
listed). The Trustee shall make the selection at least 30 days but not more than
60 days before the Redemption Date from Outstanding Notes not previously called
for redemption. The Trustee may select for redemption portions of the Principal
Amount at Maturity of Notes that have denominations larger than $1,000.

<PAGE>

                  Notes and portions of them the Trustee selects shall be in
Principal Amounts at Maturity of $1,000 or an integral multiple of $1,000.
Provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption. The Trustee shall promptly
notify the Company in writing of the Notes or portions of Notes to be redeemed.

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

                  SECTION 11.03 Notice of Redemption.

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

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

                  (a) the Redemption Date;

                  (b) the Redemption Price, or if then not ascertainable, the
manner of calculation thereof, and the amount of accrued and unpaid cash

including the Redemption Date;

                  (c) the Conversion Rate;

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

time before the close of business on the second Business Day immediately
preceding the Redemption Date, even if not otherwise convertible at such time;

                  (f) that Holders who want to convert Notes must satisfy the
requirements set forth in paragraph 9 of the Notes;

                  (g) if applicable, the election of the Company (which, subject
to the provisions of Article XVI of the Indenture, shall be irrevocable) to
deliver shares of Common Stock or to pay cash in lieu of delivery of such shares
with respect to any Notes that may be converted after mailing of such notice
prior to the Redemption Date;

                  (h) that Notes called for redemption must be surrendered to
the Paying Agent to collect the Redemption Price and accrued and unpaid cash
interest, if any, including Contingent Cash Interest, if any;

                  (i) if fewer than all the Outstanding Notes are to be
redeemed, the certificate number and Principal Amounts at Maturity of the
particular Notes to be redeemed to the extent certificated;

                                       27

<PAGE>

                  (j) the amount of interest, if any, that will be paid in
connection with such redemption and that, unless the Company defaults in making
payment of such Redemption Price and any cash interest which is due and payable,
Original Issue Discount or cash interest, including Contingent Cash Interest,
will cease to accrue on and after the Redemption Date;

                  (k) the CUSIP number of the Notes; and

                  (l) any other information the Company desires, in its own
discretion, to present.

                  At the Company's written request, the Trustee shall give the
notice of redemption to Holders in the Company's name and at the Company's
expense; provided, that the Company makes such request at least seven Business
Days (unless a shorter period shall be satisfactory to the Trustee) prior to the
date such notice of redemption must be mailed.

                  SECTION 11.04 Effect of Notice of Redemption.

                  Once notice of redemption is given, Notes called for
redemption become due and payable on the Redemption Date and at the Redemption
Price (together with accrued and unpaid cash interest, if any, including
Contingent Cash Interest, if any, to but not including the Redemption Date)
stated in the notice except for Notes which are converted in accordance with the
terms of this Indenture. Upon surrender to the Paying Agent, such Notes shall be
paid at the Redemption Price (together with accrued and unpaid cash interest, if
any, including Contingent Cash Interest, if any, to but not including the
Redemption Date) stated in the notice.

                  SECTION 11.05 Deposit of Redemption Price.

                  Prior to 10:00 a.m. New York City time, on any Redemption
Date, the Company shall deposit with the Paying Agent (or if the Company or a
Subsidiary or an Affiliate of any of them is the Paying Agent, shall segregate
and hold in trust) money sufficient to pay the Redemption Price of, and any
accrued and unpaid interest (either cash interest or Contingent Cash Interest,
if any) to but not including the Redemption Date with respect to, all Notes to
be redeemed on that date other than Notes or portions of Notes called for
redemption which on or prior thereto have been delivered by the Company to the
Trustee for cancellation or have been converted. The Paying Agent shall as
promptly as practicable return to the Company any money not required for that
purpose because of conversion of Notes pursuant to Article XVI hereof. If such
money is then held by the Company in trust and is not required for such purpose
it shall be discharged from such trust.

                  SECTION 11.06 Notes Redeemed in Part.

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

                  SECTION 11.07 Conversion Arrangement on Call for Redemption.

                                       28

<PAGE>

                  In connection with any redemption of Notes, the Company may
arrange for the purchase and conversion of any Notes called for redemption by an
agreement with one or more investment banks or other purchasers to purchase such
Notes by paying to the Trustee in trust for the Holders of Notes, on or prior to
10:00 a.m. New York City time on the Redemption Date, an amount that, together
with any amounts deposited with the Trustee by the Company for the redemption of
such Notes, is not less than the Redemption Price of, and any accrued and unpaid
interest (either cash interest or Contingent Cash Interest) with respect to,
such Notes. Notwithstanding anything to the contrary contained in this Article
XI, the obligation of the Company to pay the Redemption Prices of such Notes
shall be deemed to be satisfied and discharged to the extent such amount is so
paid by such purchasers. If such an agreement is entered into, any Notes not
duly surrendered for conversion by the Holders thereof may, at the option of the
Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such Holders and (notwithstanding anything to the contrary
contained in Article XVI) surrendered by such purchasers for conversion, all as
of immediately prior to the close of business on the second Business Day prior
to the Redemption Date, subject to payment of the above amount as aforesaid. The
Trustee shall hold and pay to the Holders whose Notes are selected for
redemption any such amount paid to it for purchase and conversion in the same
manner as it would moneys deposited with it by the Company for the redemption of
Notes. Without the Trustee's prior written consent, no arrangement between the
Company and such purchasers for the purchase and conversion of any Notes shall
increase or otherwise affect any of the powers, duties, responsibilities or
obligations of the Trustee as set forth in this Indenture, and the Company
agrees to indemnify the Trustee from, and hold it harmless against, any loss,
liability or expense arising out of or in connection with any such arrangement
for the purchase and conversion of any Notes between the Company and such
purchasers, including the costs and expenses incurred by the Trustee in the
defense of any claim or liability arising out of or in connection with the
exercise or performance of any of its powers, duties, responsibilities or
obligations under this Indenture.

                  SECTION 11.08 Purchase of Notes at Option of the Holder for
Cash.

                  (a) General. Notes shall be purchased by the Company pursuant
to paragraph 7 of the Notes as of January 15, 2009, 2014, 2019, 2024 and 2029

Principal Amount at Maturity as of January 15, 2009, of $475.66 per $1,000 of

and unpaid cash interest, if any, including Contingent Cash Interest, if any, to
the Purchase Date (each, a "Purchase Price", as applicable), at the option of
the Holder thereof, upon:

                  (i) delivery to the Paying Agent, by the Holder, of a written
         notice of purchase (a "Purchase Notice") at any time from the opening
         of business on the date that is 20 Business Days prior to a Purchase
         Date until the close of business on the Business Day immediately
         preceding such Purchase Date stating:

                           (A) the certificate number of the Note which the
                  Holder will deliver to the purchased (to the extent
                  certificated),

                                       29

<PAGE>

                  of the Note which the Holder will deliver to be purchased,
                  which portion must be a Principal Amount at Maturity of $1,000
                  or an integral multiple thereof, and

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

                  (ii) that the Holders will deliver 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 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 11.08 only if the Note 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.

                  The Company shall purchase from the Holder thereof, pursuant
to this Section 11.08, a portion of a Note 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 Note also apply to the purchase
of such portion of such Note.

                  Any purchase by the Company contemplated pursuant to the
provisions of this Section 11.08 shall be consummated by the delivery of the
consideration to be received by the Holder (together with accrued and unpaid
cash interest, if any, including Contingent Cash Interest, if any,) promptly
following the later of the Purchase Date and the time of delivery of the Note.

                  Notwithstanding anything herein to the contrary, any Holder
delivering to the Paying Agent the Purchase Notice contemplated by this Section
11.08(a) shall have the right to withdraw such Purchase Notice at any time prior
to the close of business on the Business Day prior to the Purchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 11.10 hereof.

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

                  (b) The Purchase Price of Notes in respect of which a Purchase
Notice pursuant to Section 11.08(a) hereof has been given, or a specified
percentage thereof, may only be paid by the Company with cash equal to the
aggregate Purchase Price of such Notes. The Company shall send a notice (the
"Company Notice") to the Trustee and the Holders (and to beneficial owners as
required by applicable law) not more than 60 Business Days and not less than 20
Business Days prior to such Purchase Date.

                  (c) Each Company Notice shall include a form of Purchase
Notice to be completed by a Holder of Notes and shall state:

         Indenture;

                  (iv) that Notes must be surrendered to the Paying Agent to

         Purchase Notice has been given and not withdrawn, together with any
         cash interest payable or any Contingent Cash Interest payable with
         respect thereto, will be paid promptly following the later of the

         Date; and

Purchase Price"), as of the date that is no later than 30 Business Days after
the occurrence of the Change in Control but in no event prior to the date on
which such Change in Control occurs (the "Change in Control Purchase Date"),
subject to satisfaction by or on behalf of the Holder of the requirements set
forth in Section 11.09(c) hereof.

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

                  (i) any "person" including its Affiliates or Associates (for
         the purpose of this Section 11.09 only, as the term "person" is used in
         Section 13(d)(3) or Section 14(d)(2) of the Exchange Act) other than
         the Company, its Subsidiaries or their employee benefit plans, becomes
         the beneficial owner (as the term "beneficial owner" is defined under
         Rule 13d-3 or any successor rule or regulation promulgated under the
         Exchange Act) of more than 50% of the aggregate voting power of the
         Company's Capital Stock entitled under ordinary circumstances to elect
         at least a majority of its directors; or

                  (ii) the Company is consolidated with, or merged into, another
         Person or such other Person is merged into the Company (other than a
         transaction pursuant to which the holders of 50% or more of the total
         voting power of all shares of the Company's Capital Stock entitled to
         vote generally in the election of directors immediately prior to such
         transaction have, directly or indirectly, at least 50% or more of the
         total voting power of all capital stock of the continuing or surviving
         corporation entitled to vote generally in the election of directors of
         such continuing or surviving corporation immediately after such
         transaction).

                  Notwithstanding the foregoing provisions of this Section
         11.09, no Change of Control will be deemed to have occurred in
         connection with any merger or similar transaction the purpose of which
         is to change the state of incorporation of the relevant Person.

                  "Associate" shall have the meaning ascribed to such term in
Rule 12b-2 of the General Rules and Regulations under the Exchange Act, as in
effect on the date hereof.

                  (b) Within 15 days after the occurrence of a Change in Control
or at the Company's option prior to such Change in Control but after it is
publicly announced, the Company shall mail a written notice of 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:

                  (i) briefly, the events causing a Change in Control and the
         date of such Change in Control and that the purchase of the Notes by
         the Company may be conditioned on the occurrence of a Change in
         Control;

                  (ii) the date by which the Change in Control Purchase Notice
         pursuant to this Section 11.09 must be given;

                                       32

                  (iii) the Change in Control Purchase Date;

                  (iv) the Change in Control Purchase Price and any accrued and
         unpaid cash interest payable with respect to the Notes as of the Change
         in Control Purchase Date;

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

                  (vi) the Conversion Rate and any adjustments thereto resulting
         from the Change in Control;

                  (vii) that Notes as to which a Change in Control Purchase
         Notice has been given may be converted pursuant to Article XVI hereof
         only if the Change in Control Purchase Notice has been withdrawn in
         accordance with the terms of this Indenture;

                  (viii) that Notes must be surrendered to the Paying Agent to
         collect payment of the Change in Control Purchase Price and accrued and
         unpaid cash interest, if any;

                  (ix) that the Change in Control Purchase Price for any Note as
         to which a Change in Control Purchase Notice has been duly given and
         not withdrawn, together with any accrued and unpaid cash interest
         payable, including any Contingent Cash Interest, with respect thereto,
         will be paid promptly following the later of the Change in Control
         Purchase Date and the time of surrender of such Note as described in
         Section 11.09(b)(viii) hereof;

                  (x) briefly, the procedures the Holder must follow to exercise
         rights under this Section 11.09;

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

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

                  (xiii) that, unless the Company defaults in making payment of
         such Change in Control Purchase Price and cash interest, if any on
         Notes surrendered for purchase, Original Issue Discount and any cash
         interest on Notes surrendered for purchase will cease to accrue on and
         after the Change in Control Purchase Date; and

                  (xiv) the CUSIP number of the Notes.

                  (c) A Holder may exercise its rights specified in Section
11.09(a) hereof upon delivery of a written notice of purchase (a "Change in
Control Purchase Notice") to the Paying Agent at any time prior to the close of
business on the Business Day prior to the Change in Control Purchase Date,
stating:

                  (i) the certificate number or numbers of the Note or Notes
         which the Holder will deliver to be purchased (to the extent
         certificated);

                                       33

<PAGE>

                  (ii) the portion of the Principal Amount at Maturity of the
         Note which the Holder will deliver to be purchased, which portion must
         be $1,000 or an integral multiple thereof; and

                  (iii) that such Note shall be purchased pursuant to the terms
         and conditions specified in paragraph 7 of the Notes.

                  The delivery of such Note to the Paying Agent at any time
after the delivery of the Change in Control Purchase Notice (together with all
necessary endorsements) at the offices of the Paying Agent shall be a condition
to the receipt by the Holder of the Change in Control Purchase Price therefor;
provided, however, that such Change in Control Purchase Price shall be so paid
pursuant to this Section 11.09 only if the Note 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 11.09, a portion of a Note 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 Note also apply to the purchase
of such portion of such Note.

                  Any purchase by the Company contemplated pursuant to the
provisions of this Section 11.09 shall be consummated by the delivery of the
consideration to be received by the Holder (together with accrued and unpaid
cash interest, if any), including Contingent Cash Interest, if any, promptly
following the later of the Change in Control Purchase Date and the time of
delivery of the Note to the Paying Agent in accordance with this Section 11.09.

                  Notwithstanding anything herein to the contrary, any Holder
delivering to the Paying Agent the Change in Control Purchase Notice
contemplated by this Section 11.09(c) shall have the right to withdraw such
Change in Control Purchase Notice at any time prior to the close of business on
the 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
11.10 hereof.

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

                  The Company shall not be required to comply with this Section
11.09 if a third party mails a written notice of Change in Control in the
manner, at the times and otherwise in compliance with this Section 11.09 and
repurchases all Notes for which a Change in Control Purchase Notice shall be
delivered and not withdrawn in accordance with this Section 11.09.

                  SECTION 11.10 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 11.08(a) or Section
11.09(c) hereof, as applicable, the Holder of the Note 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 is
withdrawn as specified in the following two paragraphs) thereafter be entitled

                                       34
<PAGE>

to receive solely the Purchase Price or Change in Control Purchase Price, as the
case may be, and any accrued and unpaid cash interest, including any Contingent
Cash Interest, with respect to such Note. Such Purchase Price or Change in
Control Purchase Price (which price reflects the Issue Price plus accrued
Original Issue Discount) and accrued and unpaid cash interest, including
Contingent Cash Interest, if any, shall be paid to such Holder, subject to
receipt of funds and/or Notes by the Paying Agent, promptly following the later
of (x) the Purchase Date or the Change in Control Purchase Date, as the case may
be, with respect to such Note (provided that the conditions in Section 11.08(a)
or Section 11.09(c) hereof, as applicable, have been satisfied) and (y) the time
of delivery of such Note to the Paying Agent by the Holder thereof in the manner
required by Section 11.08(a) or Section 11.09(c) hereof, as applicable. Notes in
respect of which a Purchase Notice or Change in Control Purchase Notice, as the
case may be, has been given by the Holder thereof may not be converted pursuant
to Article XVI hereof on or after the date of the delivery of such Purchase
Notice or Change in Control Purchase Notice, as the case may be, unless such
Purchase Notice or Change in Control Purchase Notice, as the case may be, has
first been validly withdrawn as specified in the following two paragraphs.

                  A Purchase Notice or Change in Control 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 in accordance with the Purchase
Notice or Change in Control Purchase Notice, as the case may be, at any time
prior to the close of business on the Business Day prior to the Purchase Date or
the Change in Control Purchase Date, as the case may be, specifying:

                  (a) the certificate number or numbers of the Note or Notes in
respect of which such notice of withdrawal is being submitted,

                  (b) the Principal Amount at Maturity of the Note or Notes with
respect to which such notice of withdrawal is being submitted, and

                  (c) the Principal Amount at Maturity, if any, of such Note
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.

                  A written notice of withdrawal of a Purchase Notice may be in
the form set forth in the preceding paragraph.

                  There shall be no purchase of any Notes pursuant to Section
11.08 or 11.09 hereof 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 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, and any
accrued and unpaid cash interest or Contingent Cash Interest with respect to
such Notes). The Paying Agent will promptly return to the respective Holders
thereof any Notes (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, and any accrued and unpaid cash
interest or Contingent Cash Interest with

                                       35
<PAGE>

respect to such Notes) 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 11.11 Deposit of Purchase Price or Change in Control
Purchase Price.

                  Prior to 10:00 a.m., New York City time, on the Business Day
following the Purchase Date or the Change in Control Purchase Date, as the case
may be, the Company shall deposit with the Trustee or with the Paying Agent (or,
if the Company or a Subsidiary or an Affiliate of either of them is acting as
the Paying Agent, shall segregate and hold in trust) an amount of money (in
immediately available funds if deposited on such Business Day) sufficient to pay
the aggregate Purchase Price or Change in Control Purchase Price, as the case
may be, of, and any accrued and unpaid cash interest including Contingent Cash
Interest, if any, with respect to all the Notes 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 11.12 Notes Purchased in Part.

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

                  SECTION 11.13 Repayment to the Company.

                  The Trustee and the Paying Agent shall promptly return to the
Company any cash that remain unclaimed as provided in paragraph 13 of the Notes,
together with interest thereon (subject to the provisions of Section 6.06
hereof), held by them for the payment of the Purchase Price or Change in Control
Purchase Price, as the case may be, or cash interest, if any, including
Contingent Cash Interest, if any; provided, however, that to the extent that the
aggregate amount of cash deposited by the Company pursuant to Section 11.11
hereof exceeds the aggregate Purchase Price or Change in Control Purchase Price,
as the case may be, of, and the accrued and unpaid cash interest, if any,
including Contingent Cash Interest, if any, with respect to, the Notes 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, whether as a result
of withdrawal or otherwise, then promptly after the second Business Day
following the Purchase Date or Change in Control Purchase Date, as the case may
be, the Trustee shall return any such excess to the Company together with
interest thereon (subject to the provisions of Section 6.06 hereof).

SECTION 2.24 Application of the Article of the Indenture Regarding Defeasance
and Covenant Defeasance.

                                       36
<PAGE>

                  The provisions of Article XIII of the Base Indenture,
including the provisions relating to defeasance and covenant defeasance of the
Notes under Sections 13.02 and 13.03 thereof, respectively, shall not apply to
the Notes.

SECTION 2.25 Conversions.

                  For the sole benefit of the Holders of the Notes, a new
Article XVI shall be added to the Base Indenture as follows:

                                   ARTICLE XVI

                                   CONVERSIONS

                  SECTION 16.01 Conversion Privilege.

                  A Holder of a Note may convert such Note into shares of Common
Stock prior to the close of business on January 15, 2034, at the times permitted
by, and subject to the provisions of this Article XVI and paragraph 9 of the
Notes. Upon determination that Holders are or will be entitled to convert their
Notes into Common Stock in accordance with paragraph 9 of the Notes, the Company
will issue a press release and use its reasonable best efforts to post such
determination on the Company's website or through such other public medium as
the Company may use at that time. The number of shares of Common Stock issuable
upon conversion of each $1,000 of Principal Amount at Maturity of Notes (the
"Conversion Rate") shall be determined in accordance with the provisions of
paragraph 9 of the Notes.

                  A Holder may convert a portion of the Principal Amount at
Maturity of a Note 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 Note also
apply to conversion of a portion of a Note.

                  The Holders' rights to convert Notes into shares of Common
Stock is subject to the Company's right to elect instead to pay each such Holder
the amount of cash set forth in the next succeeding sentence, in lieu of
delivering such shares of Common Stock, subject to the last sentence of this
paragraph. The amount of cash to be paid pursuant to Section 16.02 hereof for
each $1,000 Principal Amount at Maturity of a Note upon conversion shall be
equal to the Average Sale Price of the Common Stock for the five consecutive
Trading Days immediately following (i) the date of the Company's notice of its
election to deliver cash upon conversion, if the Company shall not have given a
notice of redemption pursuant to Section 11.03 hereof, or (ii) the Conversion
Date, in the case of a conversion following such a notice of redemption
specifying an intent to deliver cash upon conversion, in either case, multiplied
by the Conversion Rate in effect on such Conversion Date. The Company shall not
pay cash in lieu of delivering shares of Common Stock upon the conversion of any
Note pursuant to the terms of this Article XVI (other than cash in lieu of
fractional shares pursuant to Section 16.03 hereof) if there has occurred (prior
to, on or after, as the case may be, the Conversion Date or the date on which
the Company delivers its notice of whether such Note shall be converted into
Common Stock or cash pursuant to Section 16.02 hereof) and is continuing an
Event of Default (other than a default in a cash payment upon conversion of such
Note).

                  SECTION 16.02 Conversion Procedure.

                                       37
<PAGE>

                  To convert a Note, a Holder must satisfy the requirements in
paragraph 9 in the Notes. The date on which the Holder satisfies all those
requirements is the conversion date (the "Conversion Date"). The Conversion
Agent shall notify the Company of the Conversion Date within one Business Day
following the Conversion Date. Within two Business Days following the Conversion
Date, the Company shall deliver to the Holder, through the Trustee, written
notice of whether such Note shall be converted into shares of Common Stock or
paid in cash, unless the Company shall have previously delivered a notice of
redemption pursuant to Section 11.03 hereof. If the Company shall have notified
the Holder that all of such Notes shall be converted into shares of Common
Stock, the Company shall deliver to the Holder through the Conversion Agent, as
promptly as practicable but in any event no later than the tenth Business Day
following the Conversion Date a certificate for the number of full shares of
Common Stock deliverable upon the conversion and cash in lieu of any fractional
share determined pursuant to Section 16.03 hereof. Except as provided in the
last sentence in the third paragraph of Section 16.01 hereof, if the Company
shall have notified the Holder that all or a portion of such Note shall be paid
in cash, the Company shall deliver to the Holder surrendering such Note the
amount of cash payable with respect to such Note no later than the tenth
Business Day following such Conversion Date, together with a certificate for the
number of full shares of Common Stock deliverable upon the conversion (to the
extent certificated) and cash in lieu of any fractional share determined
pursuant to Section 16.03 hereof. Except as provided in the last sentence in the
third paragraph of Section 16.01 hereof, at any time prior to Maturity, the
Company may at its option elect by written notice to the Trustee and Holders of
the Notes that upon conversion of a Note at any time following the date of such
notice, the Company shall be required to deliver cash in an amount at least
equal to the accreted principal amount of the Notes converted. If the Company
makes this election, it will also be required to deliver cash only in connection
with any Principal Value Conversion (as defined in the Note) pursuant to the
second paragraph of paragraph 9 of the Note. If shares of Common Stock are
delivered as consideration, then the Person in whose name the certificate
representing such shares is registered shall be treated as a stockholder of
record of the Company on and after the Conversion Date; provided, however, that
no surrender of a Note on any date when the stock transfer books of the Company
shall be closed shall be effective to constitute the Person or Persons entitled
to receive the shares of Common Stock upon such conversion as the record holder
or holders of such shares of Common Stock on such date, but such surrender shall
be effective to constitute the Person or Persons entitled to receive such shares
of Common Stock as the record holder or holders thereof for all purposes at the
close of business on the next succeeding day on which such stock transfer books
are open; such conversion shall be at the Conversion Rate in effect on the date
that such Note shall have been surrendered for conversion, as if the stock
transfer books of the Company had not been closed. Upon conversion of a Note,
such Person shall no longer be a Holder of such Note.

                  No payment or adjustment will be made for dividends on, or
other distributions with respect to, any Common Stock except as provided in this
Article XVI. On conversion of a Note, that portion of accrued Original Issue
Discount or cash interest, if any, including Contingent Cash Interest, if any,
attributable to the period from the Issue Date of the Note through but not
including the Conversion Date, with respect to the converted Note shall not be
cancelled, extinguished or forfeited, but rather shall be deemed to be paid in
full to the Holder thereof through delivery of the Common Stock (or any cash
payment in lieu thereof) (together with the cash payment, if any, in lieu of
fractional shares) in exchange for the Note being converted pursuant to the
provisions hereof (except to the extent that Contingent Cash Interest

                                       38
<PAGE>

are required to be paid in cash as provided in paragraph 9 of the Notes); and
the Fair Market Value of such shares of Common Stock (or any cash payment in
lieu thereof) (together with any such cash payment in lieu of fractional shares)
shall be treated as delivered, to the extent thereof, first in exchange for
accrued Original Issue Discount and cash interest, if any, including Contingent
Cash Interest, if any, accrued through the Conversion Date, and the balance, if
any, of such Fair Market Value of such Common Stock (or any cash payment in lieu
thereof) (and any such cash payment in lieu of fractional shares) shall be
treated as issued in exchange for the Issue Price of the Note being converted
pursuant to the provisions hereof. Notwithstanding the foregoing, accrued cash
interest, if any, including Contingent Cash Interest, if any, will be payable
upon conversion of Notes made concurrently with or after acceleration of Notes
following an Event of Default.

                  If the Holder converts more than one Note at the same time,
the number of shares of Common Stock issuable upon the conversion shall be based
on the total Principal Amount at Maturity of all of the Notes converted.

                  If the last day on which a Note may be converted is not a
Business Day, the Note may be surrendered on the next succeeding day that is a
Business Day.

                  A Note surrendered for conversion based on (a) the Common
Stock price may be surrendered for conversion on a Conversion Date at any time
after March 31, 2004 as more fully described in paragraph 9 of the Notes, (b)
the Note being called for redemption may be surrendered for conversion at any
time prior to the close of business on the second Business Day immediately
preceding the Redemption Date, even if it is not otherwise convertible at such
time, (c) the Trading Price may be surrendered for conversion any time prior to
Maturity during the five Business Day period after any five consecutive Trading
Day Period in which the Trading Price is at certain levels more fully described
in paragraph 9 of the Notes, and (d) upon the occurrence of certain corporate
transactions more fully described in paragraph 9 of the Notes may be surrendered
for conversion at any time from and after the date which is 15 days prior to the
anticipated effective date of such transaction until 15 days after the actual
date of such transaction, and if such day is not a Business Day, the next
occurring Business Day following such day; but in each of clauses (a), (b), (c)
and (d) above, in no event later than the close of business on January 15, 2034.

                  Upon surrender of a Note that is converted in part, the
Company shall execute, and the Trustee shall authenticate and deliver to the
Holder, a new Note in an authorized denomination equal in Principal Amount at
Maturity to the unconverted portion of the Note surrendered.

                  SECTION 16.03 Fractional Shares.

                  The Company will not issue a fractional share of Common Stock
upon conversion of a Note. Instead, the Company will deliver cash for the
current market value of the fractional share. The current market value of a
fractional share shall be determined, to the nearest 1/1,000th of a share, by
multiplying the per share Sale Price of the Common Stock, on the last Trading
Day prior to the Conversion Date, by the fractional amount and rounding the
product to the nearest whole cent.

                                       39
<PAGE>

                  SECTION 16.04 Taxes on Conversion.

                  If a Holder converts a Note, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on the issue of shares
of Common Stock upon the conversion. However, the Holder shall pay any such tax
which is due because the Holder requests the shares to be issued in a name other
than the Holder's name and any income tax which is imposed on the Holder as a
result of the conversion. The Conversion Agent may refuse to deliver the
certificates representing the Common Stock being issued in a name other than the
Holder's name until the Conversion Agent receives a sum sufficient to pay any
tax which will be due because the shares are to be issued in a name other than
the Holder's name. Nothing herein shall preclude the Company from any tax
withholding or directing the withholding of any tax required by law or
regulations.

                  SECTION 16.05 Company to Provide Stock.

                  The Company shall, prior to issuance of any Notes under this
Article XVI, and from time to time as may be necessary, reserve out of its
authorized but unissued Common Stock a sufficient number of shares of Common
Stock to permit the conversion of the Notes.

                  All shares of Common Stock delivered upon conversion of the
Notes shall be newly issued shares or treasury shares, 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 created by the Company.

                  The Company will comply with all federal and state securities
laws regulating the offer and delivery of shares of Common Stock upon conversion
of Notes, if any, and will list or cause to have quoted such shares of Common
Stock on each national securities exchange or in the over-the-counter market or
such other market on which the Common Stock is then listed or quoted.

                  SECTION 16.06 Adjustment for Change in Capital Stock.

                  Except as set forth in Section 16.16 hereof, if, after the
Issue Date of the Notes, the Company:

                  (a) pays a dividend or makes a distribution on its Common
Stock in shares of its Common Stock or other Capital Stock;

                  (b) subdivides its outstanding shares of Common Stock into a
greater number of shares;

                  (c) combines its outstanding shares of Common Stock into a
smaller number of shares; or

                  (d) issues by reclassification of its Common Stock any shares
of its Capital Stock (other than rights, warrants or options for its Capital
Stock);

                                       40
<PAGE>

then the conversion privilege and the Conversion Rate in effect immediately
prior to such action shall be adjusted so that the Holder of a Note thereafter
converted may receive the number of shares or other units of Capital Stock of
the Company which such Holder would have owned immediately following such action
if such Holder had converted the Note 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 Note upon conversion of
such Note may receive shares of two or more classes of Capital Stock of the
Company, 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 XVI with respect to the Common Stock, on terms
comparable to those applicable to Common Stock in this Article XVI.

                  SECTION 16.07 Adjustment for Rights Issue.

                  Except as set forth in Sections 16.16 and 16.21 hereof, if
after the Issue Date, the Company distributes any rights, warrants or options to
all holders of its Common Stock entitling them, for a period expiring within 60
days of the issue date for each distribution, to purchase shares of Common Stock
at a price per share less than the Sale Price of the Common Stock as of the Time
of Determination, the Conversion Rate shall be adjusted in accordance with the
formula:

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

                  where:

                  R' = the adjusted Conversion Rate.

                  R = the current Conversion Rate.

                  O = the number of shares of Common Stock outstanding on the
record date for the distribution to which this Section 16.07 is being applied.

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

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

                  M = the Average Sale Price.

                  The Board of Directors shall determine Fair Market Values for
the purposes of this Section 16.07.

                                       41
<PAGE>

                  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 16.07 applies. If all of the
shares of 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 Common Stock issued
upon the exercise of such rights, warrants or options.

                  No adjustment shall be made under this Section 16.07 if the
application of the formula stated above in this Section 16.07 would result in a
value of R' that is equal to or less than the value of R.

                  SECTION 16.08 Adjustment for Other Non-Cash Distributions.

                  (a) If, after the Issue Date of the Notes, the Company
distributes to all holders of its Common Stock any of its non-cash assets,
excluding distributions of Capital Stock or equity interests referred to in
Section 16.08(b), or debt securities or any rights, warrants or options to
purchase securities of the Company (including securities but excluding
distributions of Capital Stock referred to in Section 16.06 and distributions of
rights, warrants or options referred to in Section 16.07) the Conversion Rate
shall be adjusted 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.

                  F = the Fair Market Value (on the record date for the
distribution to which this Section 16.08(a) applies) of the assets, securities,
rights, warrants or options to be distributed in respect of each share of Common
Stock in the distribution to which this Section 16.08(a) is being applied.

                  The Board of Directors shall determine Fair Market Values for
the purposes of this Section 16.08(a).

                  The adjustment shall become effective immediately after the
record date for the determination of stockholders entitled to receive the
distribution to which this Section 16.08(a) applies.

                  (b) If, after the Issue Date of the Notes, the Company pays a
dividend or makes a distribution to all holders of its Common Stock consisting
of Capital Stock of any class or

                                       42
<PAGE>

series, or similar equity interests, of or relating to a Subsidiary or other
business unit of the Company, the Conversion Rate shall be adjusted in
accordance with the formula:

                               R' = R x (1 + F/M)

                  where:

                  R' = the adjusted Conversion Rate.

                  R = the current Conversion Rate.

                  M = the average of the Post-Distribution Prices of the Common
Stock for the 10 Trading Days commencing on and including the fifth Trading Day
after the date on which "ex-dividend trading" commences for such dividend or
distribution on the principal United States exchange or market which such
securities are then listed or quoted (the "Ex-Dividend Date").

                  F = the Fair Market Value of the securities distributed in
respect of each share of Common Stock in the distribution to which this Section
16.08(b) applies, which shall be determined by multiplying the number of
securities distributed in respect of each share of Common Stock in the
distribution by the average of the Post-Distribution Prices of those securities
for the 10 Trading Days commencing on and including the fifth Trading Day after
the Ex-Dividend Date.

                  "Post-Distribution Price" of Capital Stock or any similar
equity interest on any date means the closing per unit sale price (or, if no
closing sale 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 ask
prices) on such date for trading of such units on a "when issued" basis without
due bills (or similar concept) as reported in the composite transactions for the
principal United States securities exchange on which such Capital Stock or
equity interest is traded or, if the Capital Stock or equity interest, as the
case may be, is not listed on a United States national or regional securities
exchange, as reported by the National Association of Securities Dealers
Automated Quotation System or by the National Quotation Bureau Incorporated;
provided that if on any date such units have not traded on a "when issued"
basis, the Post-Distribution Price shall be the closing per unit sale price (or,
if no closing sale 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
ask prices) on such date for trading of such units on a "regular way" basis
without due bills (or similar concept) as reported in the composite transactions
for the principal United States securities exchange on which such Capital Stock
or equity interest is traded or, if the Capital Stock or equity interest, as the
case may be, is not listed on a United States national or regional securities
exchange, as reported by the National Association of Securities Dealers
Automated Quotation System or by the National Quotation Bureau Incorporated. In
the absence of such quotation, the Company shall be entitled to determine the
Post-Distribution Price on the basis of such quotations which reflect the
post-distribution value of the Capital Stock or equity interests as it considers
appropriate.

                  (c) In the event that, with respect to any distribution to
which this Section 16.08 would otherwise apply, the difference "M-F" as defined
in the formula set forth in this Section 16.08 is less than $1.00 or "F" is
equal to or greater than "M", then the adjustment provided by

                                       43
<PAGE>

Section 16.08 shall not be made and in lieu thereof the provisions of Section
16.16 shall apply to such distribution.

                  SECTION 16.09 Adjustment for Cash Distributions.

                  In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock cash, excluding (i) any dividend
or distribution in connection with the liquidation, dissolution or winding up of
the Company, whether voluntary or involuntary or (ii) any quarterly cash
dividend on the Common Stock to the extent that the aggregate cash dividend per
share of Common Stock in respect of any quarter does not exceed $0.09625 (as
such $0.09625 shall be adjusted for specific changes in the capitalization of
the Company upon recapitalizations, reclassifications, stock splits, stock
dividends, reverse stock splits, stock consolidations and similar transactions)
(the "Dividend Threshold Amount"), then, in such case, the Conversion Rate shall
be increased so that the Conversion Rate shall equal the rate determined by
multiplying the Conversion Rate in effect immediately prior to the close of
business on such record date by a fraction,

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

                  (ii) the denominator of which shall be the Current Market
         Price on such record date less the amount of cash so distributed
         applicable to one share of Common Stock (determined as set forth
         below),

such adjustment to be effective immediately prior to the opening of business on
the day following the record date for such dividend or distribution; provided
that if the portion of the cash so distributed applicable to one share of Common
Stock is equal to or greater than the Current Market Price on the record date,
in lieu of the foregoing adjustment, adequate provision shall be made so that
each Holder of Notes shall have the right to receive upon conversion the amount
of cash such Holder would have received had such Holder converted each Note on
the Record Date. If any such dividend or distribution is not so paid or made,
the Conversion Rate shall again be adjusted to be the Conversion Rate that would
then be in effect if such dividend or distribution had not been declared. If any
adjustment is required to be made as set forth in this Section 16.09 as a result
of a distribution that is a quarterly cash dividend, such adjustment shall be
only based upon the amount by which such distribution exceeds the Dividend
Threshold Amount. If an adjustment is required to be made as set forth in this
Section 16.09 above as a result of a distribution that is not a quarterly cash
dividend, such adjustment shall be based upon the full amount of the
distribution. If an adjustment or readjustment is made to the Conversion Rate
pursuant to this Article XVI (other than any adjustment pursuant to this Section
16.09), an appropriate inversely proportional adjustment shall be made to the
Dividend Threshold Amount.

                  SECTION 16.10 Adjustment for Tender Offers or Exchange Offers.

                  In case a tender or exchange offer made by the Company or any
Subsidiary for all or any portion of the Common Stock shall expire and such
tender or exchange offer (as amended upon the expiration thereof) shall require
the payment to stockholders of consideration per share of Common Stock having a
Fair Market Value (as determined by the Board of Directors, whose

                                       44
<PAGE>

determination shall be conclusive and described in a resolution of the Board of
Directors) that as of the last time (the "Expiration Time") tenders or exchanges
may be made pursuant to such tender or exchange offer (as it may be amended)
exceeds the average of the Closing Sale Price of a share of Common Stock for
each of the 10 consecutive Trading Days next succeeding the Expiration Time, the
Conversion Rate shall be increased so that the same shall equal the rate
determined by multiplying the Conversion Rate in effect immediately prior to the
Expiration Time by a fraction,

                  (i)      the numerator of which shall be the sum of (x) the
         Fair Market Value (determined as aforesaid) of the aggregate
         consideration payable to stockholders based on the acceptance (up to
         any maximum specified in the terms of the tender or exchange offer) of
         all shares validly tendered or exchanged and not withdrawn as of the
         Expiration Time (the shares deemed so accepted up to any such maximum,
         being referred to as the "Purchased Shares") and (y) the product of the
         number of shares of Common Stock outstanding (less any Purchased
         Shares) at the Expiration Time and the average of the Closing Sale
         Price of a share of Common Stock for each of the 10 consecutive Trading
         Days next succeeding the Expiration Time, and

                  (ii)     the denominator of which shall be the number of
         shares of Common Stock outstanding (including any tendered or exchanged
         shares) at the Expiration Time multiplied by the average of the Closing
         Sale Price of a share of Common Stock for each of the 10 consecutive
         Trading Days next succeeding the Expiration Time,

such adjustment to become effective immediately prior to the opening of business
on the day following the Expiration Time. If the Company is obligated to
purchase shares pursuant to any such tender or exchange offer, but the Company
is permanently prevented by applicable law from effecting any such purchases or
all such purchases are rescinded, the Conversion Rate shall again be adjusted to
be the Conversion Rate that would then be in effect if such tender or exchange
offer had not been made.

                  SECTION 16.11 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 and all adjustments that are
made and carried forward shall be taken in the aggregate in order to determine
if the 1% threshold is met.

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

                  SECTION 16.12 When No Adjustment Required.

                  No adjustment need be made for a transaction referred to in
Section 16.06, 16.07, 16.08, 16.09, 16.10 or 16.16 hereof if Holders of Notes
may participate in the transaction. Such participation by Holders of Notes may
include participation without conversion or upon conversion; provided, that, if
such participation is upon conversion, an adjustment shall be made at such time
as the Holders are no longer entitled to participate.

                                       45
<PAGE>

                  No adjustment need be made for rights to purchase Common Stock
pursuant to a Company plan for reinvestment of dividends or interest.

                  Unless otherwise required by a provision of this Article XVI,
no adjustment need be made for a change in the par value or no par value of the
Common Stock.

                  To the extent the Notes become convertible into cash, assets,
property or securities (other than Capital Stock of the Company), subject to
paragraph 9 of the Notes, pursuant to this Article XVI, no adjustment need be
made thereafter as to the cash, assets, property or such securities. Interest
will not accrue on the cash.

                  No adjustment will be made pursuant to this Article XVI that
would result, through the application of two or more provisions hereof, in the
duplication of any adjustment.

                  SECTION 16.13 Notice of Adjustment.

                  Whenever the Conversion Rate is adjusted, the Company shall
promptly mail to Holders of Notes a notice of the adjustment. The Company shall
file with the Trustee and the Conversion Agent such notice of adjustment and an
Officers' Certificate briefly stating the facts requiring the adjustment and the
manner of computing it. Upon receipt by it of such notice, and at the written
request of the Company, the Conversion Agent will promptly mail such notice to
Holders of Notes at the Company's expense. The Officers' Certificate shall be
conclusive evidence that the adjustment is correct. Neither the Trustee nor any
Conversion Agent shall be under any duty or responsibility and shall have no
liability with respect to any such certificate and the calculations relating to
such adjustment except the duty and responsibility to exhibit the same to any
Holder desiring inspection thereof.

                  SECTION 16.14 Voluntary Increase.

                  The Company from time to time may increase the Conversion Rate
by any amount for any period of time. Whenever the Conversion Rate is increased,
the Company shall mail to Holders of Notes 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 16.06,
16.07, 16.08, 16.09, 16.10 or 16.16 hereof.

                  SECTION 16.15 Notice of Certain Transactions.

                  If:

                  (a) the Company takes any action that would require an
adjustment in the Conversion Rate pursuant to Section 16.06, 16.07, 16.08, 16.09
or 16.10 hereof (unless no adjustment is to occur pursuant to Section 16.12
hereof); or

                                       46
<PAGE>

                  (b) the Company takes any action that would require a
supplemental indenture pursuant to Section 16.16; or

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

then the Company shall mail to Holders of Notes 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 16.16 Reorganization of Company; Special
Distributions.

                  If the Company is a party to a transaction subject to Article
VIII hereof (other than a sale of all or substantially all of the assets of the
Company in a transaction in which the holders of Common Stock immediately prior
to such transaction do not receive securities, cash, property or other assets of
the Company or any other Person) or a merger or binding share exchange which
reclassifies or changes its outstanding Common Stock, the Person obligated to
deliver securities, cash or other assets upon conversion of Notes shall, no
later than the closing date of such transaction, enter into a supplemental
indenture. If the issuer of securities deliverable upon conversion of Notes is
an Affiliate of the successor company, that issuer shall, no later than the
closing date of such transaction, join in the supplemental indenture.

                  The supplemental indenture shall provide that the Holder of a
Note 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 Note
immediately before the effective date of the transaction, assuming (to the
extent applicable) that such Holder was not a constituent Person or an Affiliate
of a constituent Person to such transaction. 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 XVI. The successor Company shall
mail to Holders of Notes a notice briefly describing the supplemental indenture.

                  If this Section applies, none of Sections 16.06, 16.07, 16.09
nor 16.10 hereof shall apply.

                  If the Company makes a distribution to all holders of its
Common Stock of any of its assets, or debt securities or any rights, warrants or
options to purchase securities of the Company that would otherwise result in an
adjustment in the Conversion Rate pursuant to the provisions of Section 16.08
hereof, then, from and after the record date for determining the holders of
Common Stock entitled to receive the distribution, a Holder of a Note that
converts such Note in accordance with the provisions of this Indenture shall
upon such conversion be entitled to receive, in addition to the shares of Common
Stock into which the Note 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 Note immediately prior to the record
date for determining the holders of Common Stock entitled to receive the
distribution.

                  SECTION 16.17 Company Determination Final.

                  Whenever adjustments to the Conversion Rate are called for
pursuant to Article XVI, such adjustments shall be made to the Conversion Rate
as may be necessary or appropriate to effectuate the intent of this Article XVI
and to avoid unjust or inequitable results as determined in good faith by the
Board of Directors.

                  Any determination that the Company or the Board of Directors
must make pursuant to Section 16.03, 16.06, 16.07, 16.08, 16.09, 16.10, 16.11,
16.12, 16.16 or 16.19 hereof is conclusive.

                  SECTION 16.18 Trustee's Adjustment Disclaimer.

                  The Trustee has no duty to determine when an adjustment under
this Article XVI should be made, how it should be made or what it should be and
shall have no liability with respect to the calculation of such adjustment. The
Trustee has no duty to determine whether a supplemental indenture under Section
16.16 hereof need be entered into or whether any provisions of any supplemental
indenture are correct. The Trustee shall not be accountable for and makes no
representation as to the validity or value of any securities or assets issued
upon conversion of Notes. The Trustee shall not be responsible for the Company's
failure to comply with this Article XVI. Each Conversion Agent (other than the
Company or an Affiliate of the Company) shall have the same protection under
this Section 16.18 as the Trustee.

                  SECTION 16.19 Simultaneous Adjustments.

                  If more than one issuance, distribution, subdivision, tender
offer or combination or other event to which Article XVI applies occurs during
the period applicable for calculating adjustments to the Conversion Rate, such
adjustments shall be calculated for such period in a manner determined by the
Board of Directors to most appropriately reflect the combined impact of such
issuance, distribution, tender offer, subdivision or combination or other event
on the Conversion Rate of the Common Stock during such period.

                  SECTION 16.20 Successive Adjustments.

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

                  SECTION 16.21 Rights Issued in Respect of Common Stock Issued
Upon Conversion.

                  Each share of Common Stock issued upon conversion of Notes
pursuant to this Article XVI shall be entitled to receive the appropriate number
of Common Stock or Preferred Stock purchase rights, as the case may be (the
"Rights"), if any, that all shares of Common Stock are entitled to receive and
the certificates representing the Common Stock issued upon such conversion shall
bear such legends, if any, in each case as may be provided by the terms of any
stockholder rights agreement adopted by the Company, as the same may be amended
from time to time (in each case, a "Rights Agreement"). If such Rights Agreement
requires that each share

                                       48
<PAGE>

of Common Stock issued upon conversion of Notes at any time prior to the
distribution of separate certificates representing the Rights be entitled to
receive such Rights, then, notwithstanding anything else to the contrary in the
foregoing sections of this Article XVI, there shall not be any adjustment to the
conversion privilege or Conversion Rate or any other term or provision of the
Notes as a result of the issuance of Rights, the distribution of separate
certificates representing the Rights, the exercise or redemption of such Rights
in accordance with any such Rights Agreement, or the termination or invalidation
of such Rights. Notwithstanding the foregoing, if a Holder of Notes exercising
its right of conversion after the distribution of Rights pursuant to a "Rights
Agreement" is not entitled to receive the Rights that would otherwise be
attributable (but for the date of conversion) to the shares of Common Stock to
be received upon such conversion, if any, the Conversion Rate will be adjusted
as though the Rights were being distributed to holders of Common Stock on the
Conversion Date. If such an adjustment is made and such Rights are later
redeemed, invalidated or terminated, then a corresponding reversing adjustment
will be made to the Conversion Rate on a equitable basis.

SECTION 2.26 Tax Matters.

                  For the sole benefit of the Holders of the Notes, a new
Article XVII shall be added to the Base Indenture as follows:

                                  ARTICLE XVII

                                   TAX MATTERS

                  SECTION 17.01 Tax Treatment.

                  The parties hereto hereby agree, and each Holder and each
beneficial owner of a Note, by purchasing or holding a Note or a beneficial
interest in a Note hereby agrees (in the absence of a change in applicable law
requiring a contrary treatment):

                  (i)      to treat the Notes as indebtedness of the Company for
         all United States federal income tax purposes; and

                  (ii)     to treat the Notes as debt instruments that are
         subject to U.S. Treasury Regulation section 1.1275-4(b).

                  Notwithstanding any other provision of this Indenture, from
the commencement of discussions with respect to the transactions contemplated
hereby, each party (and each employee, representative or other agent of such
party) may disclose to any and all Persons, without limitation of any kind, the
tax treatment and tax structure (as such terms are used in Sections 6011, 6111
and 6112 of the United States Internal Revenue Code of 1986, as amended, and the
Treasury Regulations promulgated thereunder) of the transactions contemplated by
this Indenture and all materials of any kind (including opinions or other tax
analyses) that are provided relating to such tax treatment and tax structure,
other than any information for which nondisclosure is reasonably necessary in
order to comply with applicable securities laws, and the ability of each party
and their respective representatives, Affiliates, employees, officers, directors
or other agents to consult any tax advisor, including an independent tax
advisor, regarding the

                                       49
<PAGE>

tax treatment or tax structure of the transactions hereunder (and any
transactions related thereto) shall not be restricted or limited in any manner.

                  SECTION 17.02 Comparable Yield and Projected Payment Schedule.

                  Solely for purposes of applying U.S. Treasury Regulation
section 1.1275-4 to the Notes:

                  (a) for United States federal income tax purposes, ordinary
interest income shall accrue with respect to Outstanding Notes as tax original
issue discount ("Tax Original Issue Discount") according to the "noncontingent
bond method," as set forth in U.S. Treasury Regulation section 1.1275-4(b) using
a comparable yield of 7.00%, compounded semiannually, and the projected payment
schedule attached as Annex 1 to this Indenture;

                  (b) the Company shall file with the Trustee promptly at the
end of each calendar year (i) a written notice specifying the amount of Tax
Original Issue Discount for United States federal income tax purposes (including
daily rates and accrual periods) accrued on Outstanding Notes as of the end of
such year and (ii) such other specific information relating to such Tax Original
Issue Discount that the Company determines to be relevant under the Internal
Revenue Code of 1986, as amended, including the amount of any adjustment made
under the noncontingent bond method to account for the amount of any difference
between the amount of an actual payment and the amount of a projected payment;
and

                  (c) the Company acknowledges and agrees, and each Holder and
each beneficial owner of a Note, by purchasing or holding a Note or beneficial
interest in a Note, shall be deemed to acknowledge and agree that (in the
absence of an administrative determination or judicial ruling to the contrary)
(i) each Holder and each beneficial owner of a Note shall be bound by the
Company's determination of the projected payment schedule and comparable yield
within the meaning of U.S. Treasury Regulation Section 1.275-4(b), (ii) the
comparable yield means the yield at which the Company would issue, as of the
Issue Date, a fixed rate, nonconvertible debt instrument with no contingent
payments, but with terms and conditions otherwise comparable to those of the
Notes, (iii) the projected payment schedule is determined on the basis of an
assumption of compound stock price growth, (iv) the fair market value of Common
Stock received by a Holder or beneficial owner of a Note upon conversion of such
Note shall be treated as a contingent payment under U.S. Treasury Regulation
section 1.1275-4(b), (v) the comparable yield and the projected payment schedule
are not determined for any purpose other than for the purpose of applying U.S.
Treasury Regulation section 1.1275-4(b)(4) to the Notes, and (vi) the comparable
yield and the projected payment schedule do not constitute a projection or
representation regarding the actual amounts payable on the Notes.

SECTION 2.27 Subordination of Notes.

                  For the sole benefit of the Holders of the Notes, a new
Article XVIII shall be added to the Base Indenture as follows:

                                       50
<PAGE>

                                  ARTICLE XVIII

                             SUBORDINATION OF NOTES

                  Section 18.01. Notes Subordinate to Senior Indebtedness.

                  The Company covenants and agrees, and each Holder of a Note,
by his acceptance thereof, likewise covenants and agrees, that, to the extent
and in the manner hereinafter set forth in this Article XVIII, the Indebtedness
represented by the Note, including Original Issue Discount, and the payment of
the principal of, premium, if any, and interest, including Contingent Cash
Interest, if any, on, the Note are hereby expressly made subordinate and subject
in right of payment as provided in this Article XVIII to the prior payment in
full of all Senior Indebtedness.

                  This Article XVIII shall constitute a continuing offer to all
Persons who, in reliance upon such provisions, become holders of, or continue to
hold, Senior Indebtedness; and such provisions are made for the benefit of the
holders of Senior Indebtedness; and such holders are made obligees hereunder and
they and each of them may enforce such provisions.

                  Section 18.02. Payment Over of Proceeds Upon Dissolution, etc.

                  In the event of (a) any insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, reorganization or other similar
case or proceeding in connection therewith, commenced by or against the Company
or in respect of its assets, or (b) any liquidation, dissolution or other
winding up of the Company, whether voluntary or involuntary, or whether or not
involving insolvency or bankruptcy, or (c) any assignment for the benefit of
creditors or any other marshaling of assets or liabilities of the Company, then
and in any such event:

                  (i) the holders of Senior Indebtedness shall be entitled to
receive payment in full of all amounts due on or in respect of Senior
Indebtedness before the Holders of the Notes are entitled to receive any payment
or distribution of any kind or character (excluding any Permitted Junior
Payment) on account of the principal of, premium, if any, or interest on the
Notes or on account of the purchase, redemption, defeasance or other acquisition
of, or in respect of, the Notes; and

                  (ii) any payment or distribution of assets of the Company of
any kind or character, whether in cash, property or securities (excluding any
Permitted Junior Payment), by set-off or otherwise, to which the Holders or the
Trustee would be entitled but for the provisions of this Article XVIII shall be
paid by the liquidating trustee or agent or other Person making such payment or
distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee
or otherwise, directly to the holders of Senior Indebtedness or their
representative or representatives or to the trustee or trustees under any
indenture under which any instruments evidencing any of such Senior Indebtedness
may have been issued, ratably according to the aggregate amounts remaining
unpaid on account of the Senior Indebtedness held or represented by each, to the
extent necessary to make payment in full, of all Senior Indebtedness remaining
unpaid, after

                                       51
<PAGE>

giving effect to any concurrent payment or distribution to the holders of such
Senior Indebtedness; and

                  (iii) in the event that, notwithstanding the foregoing
provisions of this Section 18.02, the Trustee or the Holder of any Note shall
have received any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities (excluding any Permitted
Junior Payment), in respect of principal, premium, if any, and interest,
including Contingent Cash Interest, if any on the Notes before all Senior
Indebtedness is paid in full, then and in such event such payment or
distribution (excluding any Permitted Junior Payment) shall be paid over or
delivered forthwith to the liquidating trustee or agent or other Person making
payments or distributions of assets of the Company for application to the
payment of all Senior Indebtedness remaining unpaid, to the extent necessary to
pay all Senior Indebtedness in full after giving effect to any concurrent
payment or distribution to or for the holders of Senior Indebtedness.

                  The consolidation of the Company with, or the merger of the
Company with or into, another Person or the liquidation or dissolution of the
Company following the sale, assignment, conveyance, transfer, lease or other
disposal of its properties and assets substantially as an entirety to another
Person upon the terms and conditions set forth in Article VIII shall not be
deemed a dissolution, winding up, liquidation, reorganization, assignment for
the benefit of creditors or marshaling of assets and liabilities of the Company
for the purposes of this Section 18.02 if the Person formed by such
consolidation or the surviving entity of such merger or the Person which
acquires by sale, assignment, conveyance, transfer, lease or other disposal of
such properties and assets substantially as an entirety, as the case may be,
shall, as a part of such consolidation, merger, sale, assignment, conveyance,
transfer, lease or other disposal, comply with the conditions set forth in
Article VIII.

                  Section 18.03. Suspension of Payment When Designated Senior
Indebtedness in Default.

                  (a) Unless Section 18.02 shall be applicable, upon the
occurrence and during the continuance of any default in the payment of any
Designated Senior Indebtedness beyond any applicable grace period (a "Payment
Default") and after the receipt by the Trustee from a Senior Representative of
holders of any Designated Senior Indebtedness of written notice of such default,
no payment or distribution of any assets of the Company or any Subsidiary of any
kind or character (excluding any Permitted Junior Payment) may be made by the
Company on account of the principal of, premium, if any, or interest, including
Contingent Cash Interest, if any, on, the Notes, or on account of the purchase,
redemption or other acquisition of or in respect of, the Notes unless and until
such Payment Default shall have been cured or waived or shall have ceased to
exist or such Designated Senior Indebtedness shall have been discharged or paid
in full, after which the Company shall (subject to the other provisions of this
Article XVIII) resume making any and all required payments in respect of the
Notes, including any missed payments.

                  (b) Unless Section 18.02 shall be applicable, (1) upon the
occurrence and during the continuance of any non-payment default or non-payment
event of default with respect to any Designated Senior Indebtedness pursuant to
which the maturity thereof may then be accelerated immediately (a "Non-payment
Default") and (2) after the receipt by the Trustee and the

                                       52
<PAGE>

Company from a Senior Representative of holders of any Designated Senior
Indebtedness of written notice of such Non-payment Default, no payment or
distribution of any assets of the Company of any kind or character (excluding
any Permitted Junior Payment) may be made by the Company on account of the
principal of, premium, if any, or interest on, the Notes, or on account of the
purchase, redemption or other acquisition of, or in respect of, the Notes for
the period specified below ("Payment Blockage Period").

                  (c) The Payment Blockage Period shall commence upon the
receipt of notice of the Non-payment Default by the Trustee from a Senior
Representative of holders of Designated Senior Indebtedness and shall end on the
earliest of (i) the 179th day after such commencement, (ii) the date on which
such Non-payment Default (and all other Non-payment Defaults as to which notice
is given after such Payment Blockage Period is initiated) is cured, waived or
ceases to exist or on which such Designated Senior Indebtedness is discharged or
paid in full, or (iii) the date on which such Payment Blockage Period (and all
Non-payment Defaults as to which notice is given after such Payment Blockage
Period is initiated) shall have been terminated by written notice to the Company
or the Trustee from the Senior Representative initiating such Payment Blockage
Period, after which, in the case of clauses (i), (ii) and (iii), the Company
shall promptly resume making any and all required payments in respect of the
Notes, including any missed payments. In no event will a Payment Blockage Period
extend beyond 179 days from the date of the receipt by the Trustee of the notice
initiating such Payment Blockage Period (such 179-day period referred to as the
"Initial Period"). Any number of notices of Non-payment Defaults may be given
during the Initial Period; provided that during any period of 365 consecutive
days only one Payment Blockage Period, during which payment of principal of,
premium, if any, or interest on, the Notes may not be made, may commence and the
duration of such period may not exceed 179 days. No Non-payment Default with
respect to any Designated Senior Indebtedness that existed on the date of the
commencement of any Payment Blockage Period can be made the basis for the
commencement of a second Payment Blockage Period. The Company shall deliver a
written notice to the Trustee promptly after the date on which any Non-payment
Default is cured or waived or ceases to exist or on which the Designated Senior
Indebtedness related thereto is discharged or paid in full, and the Trustee is
authorized to act in reliance on such notice and shall have no liability with
respect thereto.

                  (d) In the event that, notwithstanding the foregoing, the
Company shall make any payment to the Trustee or the Holder of any Note
prohibited by the foregoing provisions of this Section 18.03, then and in such
event such payment shall be paid over and delivered forthwith to a Senior
Representative of the holders of the Designated Senior Indebtedness or as a
court of competent jurisdiction shall direct.

                  Section 18.04. Payment Permitted if No Default.

                  Nothing contained in this Article XVIII, elsewhere in this
Indenture or in any of the Notes shall prevent the Company, at any time except
during the pendency of any case, proceeding, receivership, reorganization,
dissolution, liquidation or other winding-up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of the Company referred
to in Section 18.02 or under the conditions described in Section 18.03, from
making payments at any time of principal of, premium, if any, or interest on the
Notes.

                  Section 18.05. Subrogation to Rights of Holders of Senior
Indebtedness.

                  After the payment in full of all Senior Indebtedness, the
Holders of the Notes shall be subrogated to the rights of the holders of such
Senior Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of,
premium, if any, and interest, including Contingent Cash Interest, if any, on
the Notes shall be paid in full. For purposes of such subrogation, no payments
or distributions to the holders of Senior Indebtedness of any cash, property or
securities to which the Holders of the Notes or the Trustee would be entitled
except for the provisions of this Article XVIII, and no payments over pursuant
to the provisions of this Article XVIII to the holders of Senior Indebtedness by
Holders of the Notes or the Trustee, shall, as among the Company and its
creditors other than holders of Senior Indebtedness and the Holders of the
Notes, be deemed to be a payment or distribution by the Company to or on account
of the Senior Indebtedness.

                  Section 18.06. Provisions Solely to Define Relative Rights.

                  The provisions of this Article are intended solely for the
purpose of defining the relative rights of the Holders of the Notes on the one
hand and the holders of Senior Indebtedness on the other hand. Nothing contained
in this Article XVIII or elsewhere in this Indenture or in the Notes is intended
to or shall (a) impair, as among the Company and its creditors other than
holders of Senior Indebtedness and the Holders of the Notes, the obligation of
the Company, which is absolute and unconditional, to pay to the Holders of the
Notes the principal of, premium, if any, and interest, including Contingent Cash
Interest, if any, on, the Notes as and when the same shall become due and
payable in accordance with their terms; or (b) affect the relative rights
against the Company of the Holders of the Notes and creditors of the Company,
other than the holders of Senior Indebtedness; or (c) prevent the Trustee or the
Holder of any Note from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
under this Article XVIII of the holders of Senior Indebtedness (1) in any case,
proceeding, dissolution, liquidation or other winding up, assignment for the
benefit of creditors or other marshaling of assets and liabilities of the
Company referred to in Section 18.02, to receive, pursuant to and in accordance
with such Section, cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder, or (2) under the conditions specified
in Section 18.03, to prevent any payment prohibited by such Section or enforce
their rights pursuant to Section 18.03(d).

                  Section 18.07. Trustee to Effectuate Subordination.

                  Each Holder of a Note by such Holder's acceptance thereof
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination provided in
this Article XVIII and appoints the Trustee such Holder's attorney-in-fact for
any and all such purposes, including, in the event of any dissolution,
winding-up, liquidation or reorganization of the Company whether in bankruptcy,
insolvency, receivership proceedings, or otherwise, the timely filing of a claim
for the unpaid balance of the Indebtedness of the Company owing to such Holder
in the form required in such proceedings and the causing of such claim to be
approved.

                                       54
<PAGE>

                  Section 18.08. No Waiver of Subordination Provisions.

                  (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.

                  (b) Without limiting the generality of subsection (a) of this
Section 18.08, the holders of Senior Indebtedness may, at any time and from time
to time, without the consent of or notice to the Trustee or the Holders of the
Notes, without incurring responsibility to the Holders of the Notes and without
impairing or releasing the subordination provided in this Article XVIII or the
obligations hereunder of the Holders of the Notes to the holders of Senior
Indebtedness, do any one or more of the following: (1) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (2) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (3) release any Person liable in any manner for the collection or
payment of Senior Indebtedness; and (4) exercise or refrain from exercising any
rights against the Company and any other Person; provided, however, that in no
event shall any such actions limit the right of the Holders of the Notes to take
any action to accelerate the maturity of the Notes pursuant to Article V of this
Indenture or to pursue any rights or remedies hereunder or under applicable laws
if the taking of such action does not otherwise violate the terms of this
Article XVIII.

                  Section 18.09. Notice to Trustee.

                  (a) The Company shall give prompt written notice to the
Trustee of any fact known to the Company which would prohibit the making of any
payment to or by the Trustee in respect of the Notes. Notwithstanding the
provisions of this Article XVIII or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts which
would prohibit the making of any payment to or by the Trustee in respect of the
Notes, unless and until the Trustee shall have received written notice thereof
from the Company or a holder of Senior Indebtedness or from a Senior
Representative or any trustee, fiduciary or agent therefor; and, prior to the
receipt of any such written notice, the Trustee shall be entitled in all
respects to assume that no such facts exist; provided, however, that if the
Trustee shall not have received the notice provided for in this Section by Noon,
New York City time, on the Business Day prior to the date upon which by the
terms hereof any money may become payable for any purpose (including, without
limitation, the payment of the principal of, premium, if any, or interest,
including Contingent Cash Interest, if any on any Note), then, anything herein
contained to the contrary notwithstanding, but without limiting the rights and
remedies of the holders of Senior Indebtedness, a Senior Representative or any
trustee, fiduciary or agent thereof, the Trustee shall have full power and
authority to receive such money and to apply the same to the purpose for which
such money was received and shall not be affected by any notice to the contrary
which may be received by it after such time and date; nor shall the Trustee be
charged with knowledge of the curing of any default or the elimination of the
act or condition preventing any such payment unless and until the Trustee shall
have received an Officers' Certificate to

                                       55
<PAGE>

such effect and, in the case of any written notice under Section 18.03 from a
Senior Representative of any Designated Senior Indebtedness, written
confirmation thereof from such Senior Representative.

                  (b) The Trustee shall be entitled to rely on the delivery to
it of a written notice to the Trustee and the Company by a Person representing
himself to be a Senior Representative or a holder of Senior Indebtedness (or a
trustee, fiduciary or agent therefor) to establish that such notice has been
given by a Senior Representative or a holder of Senior Indebtedness (or a
trustee, fiduciary or agent therefor); provided, however, that failure to give
such notice to the Company shall not affect in any way the ability of the
Trustee to rely on such notice. In the event that the Trustee determines in good
faith that further evidence is required with respect to the right of any Person
as a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article XVIII, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person and the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article XVIII, and if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

                  Section 18.10. Reliance on Judicial Orders or Certificates.

                  Upon any payment or distribution of assets of the Company
referred to in this Article XVIII, the Trustee and the Holders of the Notes
shall be entitled to rely upon any order or decree entered by any court of
competent jurisdiction in which any insolvency, bankruptcy, receivership,
liquidation, reorganization, dissolution, winding up or similar case or
proceeding in respect of the Company is pending, or a certificate of the trustee
in bankruptcy, receiver, liquidating trustee, custodian, assignee for the
benefit of creditors, agent or other Person making such payment or distribution,
or a certificate of a Senior Representative, delivered to the Trustee or to the
Holders of Notes for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of Senior Indebtedness
and other Indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article XVIII, provided that the foregoing shall apply only
if such court has been fully apprised of the provisions of this Article XVIII.

                  Section 18.11. Rights of Trustee as a Holder of Senior
Indebtedness; Preservation of Trustee's Rights.

                  The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article XVIII with respect to any Senior
Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness, and nothing in this Indenture shall deprive
the Trustee of any of its rights as such holder. Nothing in this Article XVIII
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 6.07.

                  Section 18.12. Article Applicable to Paying Agents.

                  In case at any time any Paying Agent other than the Trustee
shall have been appointed by the Company and be then acting under this
Indenture, the term "Trustee" as used in

                                       56
<PAGE>

this Article XVIII shall in such case (unless the context otherwise requires) be
construed as extending to and including such Paying Agent within its meaning as
fully for all intents and purposes as if such Paying Agent were named in this
Article XVIII in addition to or in place of the Trustee; provided, however, that
Section 18.11 shall not apply to the Company or any Affiliate of the Company if
it or such Affiliate acts as Paying Agent.

                  Section 18.13. No Suspension of Remedies.

                  Nothing contained in this Article XVIII shall limit the right
of the Trustee or the Holders of Notes to take any action to accelerate the
maturity of the Notes pursuant to Article V of this Indenture or to pursue any
rights or remedies hereunder or under applicable law, subject to the rights, if
any, under this Article XVIII of the holders, from time to time, of Senior
Indebtedness to receive the cash, property or securities receivable upon the
exercise of such rights or remedies.

                  Section 18.14. Trustee's Relation to Senior Indebtedness.

                  With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article XVIII, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into this Article XVIII against the Trustee. The Trustee shall not
be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and
the Trustee shall not be liable to any holder of Senior Indebtedness if it shall
in good faith mistakenly (absent gross negligence or willful misconduct) pay
over or deliver to Holders, the Company or any other Person moneys or assets to
which any holder of Senior Indebtedness shall be entitled by virtue of this

interest at the rate of 3.75% per annum of the Issue Price plus any previously
accrued Original Issue Discount, compounded semiannually, which interest shall
accrue from the date such overdue amount was originally due to the date payment
of such amount, including interest thereon, has been made or duly provided for.
All such interest shall be payable on demand. The accrual of such interest on
overdue amounts shall be in lieu of, and not in addition to, the continued
accrual of Original Issue Discount or cash interest on such overdue amounts.

                  Original Issue Discount (the difference between the Issue
Price and the Principal Amount at Maturity of the Note), in the period during
which a Note remains Outstanding, shall accrue at 3.75% per annum of the Issue
Price plus any previously accrued Original Issue Discount, beginning on January
15, 2009, on a semiannual bond equivalent basis using a 360-day year composed of
twelve 30-day months.

2.       Method of Payment.

                  Subject to the terms and conditions of the Indenture, the
Company will make payments in respect of Redemption Prices, Purchase Prices,
Change in Control Purchase Prices and at Stated Maturity to Holders who
surrender Notes to a Paying Agent to collect such payments in respect of the
Notes. In addition, the Company will pay cash interest from the Issue Date until
January 15, 2009, as more fully described in paragraph 1 hereof or Contingent
Cash Interest as more fully described in paragraph 5 below. The

                                     A-1-4
<PAGE>

Company will pay any 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 make such cash payments by check payable in such money.

3.       Paying Agent, Conversion Agent, Security Registrar and Bid Solicitation
Agent.

                  Initially, SunTrust Bank, a Georgia banking corporation (the
"Trustee"), will act as Paying Agent, Conversion Agent, Security Registrar and
Bid Solicitation Agent. The Company may appoint and change any Paying Agent,
Conversion Agent, Security Registrar or co-registrar or Bid Solicitation Agent
without notice, other than notice to the Trustee. The Company or any of its
Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion
Agent, Security Registrar or Co-Security Registrar. None of the Company, any of
its Subsidiaries or any of their Affiliates shall act as Bid Solicitation Agent.

4.       Indenture.

                  The Company issued the Notes pursuant to an Indenture dated as
of November 28, 2003, as supplemented by the First Supplemental Indenture dated
as of December 29, 2003 (collectively, the "Indenture"), between the Company and
the Trustee. The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of
1939, as in effect from time to time (the "TIA"). Capitalized terms used herein
and not defined herein have the meanings ascribed thereto in the Indenture. The
Notes are subject to all such terms, and Holders of Notes are referred to the
Indenture and the TIA for a statement of those terms.

                  The Notes are general unsecured and senior subordinated
obligations, of the Company, limited to $582,249,000 aggregate Principal Amount
at Maturity (subject to Section 3.06 of the Indenture). Subject to Section 10.07
of the Indenture, the Indenture does not limit other Indebtedness of the
Company, secured or unsecured.

5.       Contingent Cash Interest.

                  Subject to the conditions of the Indenture and the accrual and
record date provisions specified in this paragraph 5, the Company shall pay
Contingent Cash Interest to the Noteholders during any Semiannual Period, with
the initial six-month period commencing on January 16, 2009, if, but only if,
the Average Security Market Price for the five Trading Days ending on the third
Trading Day immediately preceding the first day of the applicable Semiannual
Period equals 120% or more of the Relevant Value of such Note.

                  Contingent Cash Interest, if any, will accrue and be payable
to Holders of this Note as of the Contingent Cash Interest Record Date. Original
Issue Discount will continue to accrue at 3.75% of the Issue Price plus any
previously accrued Original Issue Discount whether or not Contingent Cash
Interest is paid.

                  The amount of Contingent Cash Interest payable per $1,000
Principal Amount at Maturity hereof in respect of any Semiannual Period shall
equal the annual

                                     A-1-5
<PAGE>

rate of 0.25% of the Average Security Market Price for the five Trading Day
measuring period.

                  Upon determination that Holders of Notes will be entitled to
receive Contingent Cash Interest during a Semiannual Period, the Company shall
issue a press release and use its reasonable best efforts to post such
information on its web site or through such other public medium it may use at
the time.

                  The Company shall also notify the Trustee of the declaration
of any Regular Cash Dividends and the related record and payment dates.

                  "Regular Cash Dividends" means any quarterly cash dividends on
the Company's Common Stock as declared by the Company's Board of Directors as
part of its cash dividend payment practices and that are not designated by them
as extraordinary or special or other nonrecurring dividends.

6.       Redemption at the Option of the Company.

                  No sinking fund is provided for the Notes. The Notes are
redeemable for cash as a whole, or from time to time in part, at any time at the
option of the Company in accordance with the Indenture at the Redemption Prices
set forth below; provided that the Notes are not redeemable prior to January 15,
2009.

                  The table below shows Redemption Prices of a Note per $1,000
Principal Amount at Maturity on the dates shown below and at Stated Maturity,
which prices reflect accrued Original Issue Discount calculated to each such
date. The Redemption Price of a Note redeemed between such dates shall include
an additional amount reflecting the additional Original Issue Discount accrued
since the immediately preceding date in the table to, but not including, the
Redemption Date.

</TABLE>

                  Notwithstanding anything herein or in the Indenture, the
Purchase Price (equal to the Issue Price plus accrued Original Issue Discount to
the Purchase Date) may only be paid in cash.

                  At the option of the Holder and subject to the terms and
conditions of the Indenture, the Company shall become obligated to purchase the
Notes held by such Holder no later than 30 Business Days after the occurrence of
a Change in Control of the Company, but in no event prior to the date on which
such a Change in Control occurs, for a Change in Control Purchase Price equal to
the Issue Price plus accrued Original Issue Discount and accrued and unpaid cash
interest, if any, including Contingent Cash Interest, if any, to but not
including the Change in Control Purchase Date, which Change in Control Purchase
Price shall be paid in cash.

                  A third party may make the offer and purchase of the Notes in
lieu of the Company in accordance with 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 sufficient to pay the Purchase Price or Change in
Control Purchase Price, as the case may be, of all Notes 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 Business Day
following the Purchase Date or the Change in Control Purchase Date, as the case
may be, Original Issue Discount or cash interest (including Contingent Cash
Interest), if any, shall cease to accrue on such Notes (or portions thereof) on
such Purchase Date or Change in Control Purchase Date, as the case may be, and
the Holder thereof shall have no other rights as such (other than the right to
receive the Purchase Price or Change in Control Purchase Price, as the case may
be, if any, upon surrender of such Note).

8.       Notice of Redemption.

                  Notice of redemption will be mailed at least 30 days but not
more than 60 days before the Redemption Date to each Holder of Notes to be
redeemed at the Holder's registered address. If money sufficient to pay the
Redemption Price of, and accrued and unpaid cash interest, if any, with respect
to, all Notes (or portions thereof) to be redeemed on the Redemption Date is
deposited with the Paying Agent prior to or on the Redemption Date, on such
Redemption Date, Original Issue Discount or cash interest

                                     A-1-8
<PAGE>

(including Contingent Cash Interest), if any, shall cease to accrue on such
Notes or portions thereof. Notes in denominations larger than $1,000 of
Principal Amount at Maturity may be redeemed in part but only in integral
multiples of $1,000 of Principal Amount at Maturity.

9.       Conversion.

                  Conversion Based on Sale Price of Common Stock. Subject to the
provisions of this paragraph 9 and notwithstanding the fact that any other
condition to conversion described below has not been satisfied, Holders may
convert the Notes into Common Stock on a Conversion Date in any fiscal quarter
commencing at any time after March 31, 2004, if, as of the last day of the
preceding fiscal quarter, the Sale Price of the Common Stock for at least 20
Trading Days in a period of 30 consecutive Trading Days ending on the last
Trading Day of the most recently ended fiscal quarter, is greater than the
conversion trigger price per share. The "conversion trigger price" for any
fiscal quarter shall be 120% of the accreted conversion price per share
(calculated without giving effect to accrued cash interest, if any) of Common
Stock on the last day of such fiscal quarter. Once the foregoing condition is
satisfied for any one fiscal quarter, then the Notes will thereafter be
convertible at any time at the option of the Holder, through their maturity.

                  The "accreted conversion price per share" of Common Stock as
of any day equals the quotient of:

                  -        the Issue Price plus accrued Original Issue Discount,
                           if any, to that day; divided by

                  -        the number of shares of Common Stock issuable upon
                           conversion of $1,000 Principal Amount at Maturity of
                           Notes on that day pursuant to this paragraph 9 and
                           Article XVI of the Indenture.

                  Such accreted conversion price shall be calculated by the
Company in accordance with Article XVI of the Indenture.

                  Conversion Upon Satisfaction of Trading Price Condition.
Subject to the provisions of this paragraph 9 and notwithstanding the fact that
any other condition described herein to conversion has not been satisfied,
Holders may convert Notes into Common Stock any time prior to Maturity during
the five Business Day period after any five consecutive Trading Day period in
which the Trading Price per $1,000 Principal Amount at Maturity of the Notes for
each day of such five Trading Day period was less than 98% of the product of the
Closing Sale Price and the Conversion Rate as of such Trading Day.
Notwithstanding the foregoing, if, on the day prior to any conversion pursuant
to the preceding sentence, the Closing Sale Price of the Common Stock is greater
than the accreted conversion price per share but less than or equal to 120% of
the accreted conversion price per share, the Holders of Notes surrendered for
conversion shall receive, in lieu of Common Stock based on the Conversion Rate,
cash or Common Stock or a combination of cash and Common Stock, at the Company's
option, with a

                                     A-1-9
<PAGE>

value equal to the Issue Price plus accrued Original Issue Discount, accrued
cash interest, if any, and accrued Contingent Interest, if any, as of the
Conversion Date (a "Principal Value Conversion"). If a Holder surrenders its
Notes for a Principal Value Conversion, the Company shall notify such Holder by
the second Business Day following the Conversion Date whether the Company will
pay such Holder in cash, Common Stock or a combination of cash and Common Stock,
and in what percentage unless the Company has already provided such notice in
connection with its optional redemption of the Notes pursuant to Article XI of
the Indenture and paragraphs 6 and 8 hereof. Any Common Stock delivered upon a
Principal Value Conversion will be valued at the greater of the accreted
conversion price on the Conversion Date and the Applicable Stock Price as of the
Conversion Date. The Company will then deliver such Common Stock and/or cash to
such Holders surrendering Notes for conversion, no later than the third Business
Day following the determination of the Applicable Stock Price. In connection
with any conversion pursuant to this paragraph 9, the Trustee shall not have any
obligation to determine the Trading Price of the Notes unless the Company has
requested in writing such determination and shall have offered the Trustee
indemnity reasonably satisfactory to it regarding such determination and the
Company shall have no obligation to make such request unless a Holder provides
the Company with reasonable evidence that the Trading Price per Note would be
less than 98% of the product of the Closing Sale Price of the Common Stock and
the number of shares of Common Stock issuable upon conversion of such Note. At
such time, the Company shall instruct the Trustee in writing to determine the
Trading Price of the Notes beginning on the next Trading Day and on each
successive Trading Day until the Trading Price per such Note is greater than or
equal to 98% of the product of the Closing Sale Price of the Common Stock and
the Conversion Rate as of such Trading Day.

                  Conversion upon Redemption. Subject to the provisions of this
paragraph 9 and notwithstanding the fact that any other condition described
herein to conversion has not been satisfied, a Holder may convert into Common
Stock a Note or portion of a Note which has been called for redemption pursuant
to paragraph 6 hereof, but such Notes may be surrendered for conversion only
until the close of business on the second Business Day immediately preceding the
Redemption Date.

                  Conversion Upon Certain Distributions. Subject to the
provisions of this paragraph 9 and notwithstanding the fact that any other
condition to conversion has not been satisfied, in the event that the Company
declares a dividend or distribution described in Section 16.07 of the Indenture,
or a dividend or a distribution described in Section 16.08 of the Indenture and,
in the case of a dividend or distribution described in Section 16.08 of the
Indenture, the sum of (a) the Fair Market Value, per share, of such dividend or
distribution per share of Common Stock, and (b) the quotient of (1) the amount
of Contingent Cash Interest paid on the Notes during the Measurement Period
divided by (2) the number of shares of Common Stock issuable upon conversion of
Notes at the Conversion Rate in effect at the Ex-Dividend Time, as determined in
the Indenture, exceeds 15% of the Sale Price of the Common Stock on the Business
Day immediately preceding the date of declaration for such dividend or
distribution, the Notes may be surrendered for conversion beginning on the date
the Company gives notice to the Holders of such right, which shall not be less
than 20 days prior to the Ex-Dividend Time

                                     A-1-10
<PAGE>

for such dividend or distribution, and Notes may be surrendered for conversion
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 dividend or
distribution will not take place. For the purposes of this paragraph, the
"Measurement Period" with respect to a dividend on the Common Stock shall mean
the 365 consecutive day period ending on the date prior to the Ex-Dividend Time
with respect to such dividend.

                  Conversion Upon Occurrence of Certain Corporate Transactions.
Subject to the provisions of this paragraph 9 and notwithstanding the fact that
any other condition described herein to conversion has not been satisfied, in
the event the Company is a party to a consolidation, merger or binding share
exchange pursuant to which the Common Stock would be converted into cash,
securities or other property as set forth in Section 16.14 of the Indenture, the
Notes may be surrendered for conversion at any time from and after the date
which is 15 days prior to the date announced by the Company as the anticipated
effective time until 15 days after the actual effective date of such
transaction, and at the effective time of such transaction the right to convert
a Note into Common Stock will be deemed to have 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 Note immediately
prior to the transaction.

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

                  The initial Conversion Rate is 6.211 shares of Common Stock
per $1,000 Principal Amount at Maturity, subject to adjustment in the case of
certain events described in the Indenture. The Company will deliver cash or a
check in lieu of any fractional share of Common Stock. The ability to surrender
Notes for conversion will expire at the close of business on January 15, 2034.

                  Notes surrendered for conversion during the period from the
close of business on any Regular Record Date next preceding any Interest Payment
Date to the opening of business on such Interest Payment Date, shall be entitled
to receive such interest, in lieu of Original Issue Discount or Contingent Cash
Interest, payable on such Notes on the corresponding Interest Payment Date and
(except Notes with respect to which the Company has mailed a notice of
redemption) Notes surrendered for conversion during such periods must be
accompanied by payment of an amount equal to the interest in lieu of Original
Issue Discount or Contingent Cash Interest with respect thereto that the
registered Holder is to receive.

                  To convert a Note, a Holder must (a) complete and manually
sign the conversion notice (or complete and manually sign a facsimile of such
notice) and deliver such notice to the Conversion Agent, (b) surrender the Note
to the Conversion Agent, (c) furnish appropriate endorsements and transfer
documents if required by the Conversion Agent, the Company or the Trustee and
(d) pay any transfer or similar taxes, if required.

                  A Holder may convert a portion of a Note if the Principal
Amount at Maturity of such portion is $1,000 or an integral multiple of $1,000.
No payment or adjustment will be made for dividends on the Common Stock except
as provided in the Indenture. On conversion of a Note, accrued Original Issue
Discount and any accrued and unpaid cash interest, including Contingent Cash
Interest, attributable to the period from the Issue Date through the Conversion
Date shall not be cancelled, extinguished or forfeited, but rather shall be
deemed to be paid in full to the Holder thereof through the delivery of the
Common Stock (as cash in lieu thereof) (together with the cash payment, if any,
in lieu of fractional shares) in exchange for the Note being converted pursuant
to the terms hereof; and the Fair Market Value of such shares of Common Stock
(as cash in lieu thereof) (together with any such cash payment in lieu of
fractional shares) shall be treated as issued, to the extent thereof, first in
exchange for Original Issue Discount and any accrued and unpaid cash interest,
including Contingent Cash Interest, accrued through the Conversion Date, and the
balance, if any, of such Fair Market Value of such Common Stock (and any such
cash payments) shall be treated as issued in exchange for the Issue Price of the
Note being converted pursuant to the provisions hereof.

                  The Conversion Rate will be adjusted in accordance with
Article XVI of the Indenture for dividends or distributions on Common Stock
payable in Common Stock or other Capital Stock; subdivisions, combinations or
certain reclassifications of Common Stock; distributions to all holders of
Common Stock of certain rights to purchase Common Stock for a period expiring
within 60 days of the Issue Date at less than the Sale Price of the Common Stock
at the Time of Determination; distributions to such holders of assets or debt
securities of the Company or certain rights to purchase securities of the
Company (excluding certain cash dividends or distributions) and certain rights
pursuant to stockholder rights plans; certain dividends or distributions of
cash; and certain tender offers or exchange offers. The Company from time to
time may voluntarily increase the Conversion Rate.

                  If the Company is a party to a consolidation, merger or
binding share exchange or a transfer of all or substantially all of its assets,
or upon certain distributions described in the Indenture, the right to convert a
Note into Common Stock may be changed into a right to convert it into
securities, cash or other assets of the Company or another person.

10.      Defaulted Interest.

                  Except as otherwise specified with respect to the Notes, any
Defaulted Interest on any Note shall forthwith cease to be payable to the
registered Holder thereof on the relevant Regular Record Date or accrual date,
as the case may be, and such Defaulted Interest shall be paid by the Company as
provided for in Section 3.07 of the Indenture.

11.      Denominations; Transfer; Exchange.

                  The Notes are in fully registered form, without coupons, in
denominations of $1,000 of Principal Amount at Maturity and integral multiples
of $1,000. A Holder

                                     A-1-12
<PAGE>

may transfer or exchange Notes in accordance with the Indenture. The Registrar
may require a Holder, among other things, to furnish appropriate endorsements
and transfer documents and to pay any taxes and fees required by law or
permitted by the Indenture. The Registrar need not transfer or exchange any
Notes selected for redemption (except, in the case of a Note to be redeemed in
part, the portion of the Note not to be redeemed) or any Notes 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 Note to be purchased in part, the
portion of the Note not to be purchased) or any Notes for a period of 15 days
before the mailing of a notice of redemption of Notes to be redeemed.

12.      Persons Deemed Owners.

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

13.      Unclaimed Money or Notes.

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

14.      Amendment; Waiver.

                  Subject to certain exceptions set forth in the Indenture, (a)
the Indenture or the Notes may be amended with the written consent of the
Holders of a majority in aggregate Principal Amount at Maturity of the Notes at
the time outstanding and (b) certain Events of Default may be waived with the
written consent of the Holders of a majority in aggregate Principal Amount at
Maturity of the Notes at the time outstanding. Subject to certain exceptions set
forth in the Indenture, without the consent of any Holder of the Notes, the
Company and the Trustee may amend the Indenture or the Notes as set forth in
Section 9.01 of the Indenture.

15.      Defaults and Remedies.

                  Under the Indenture, Events of Default include (a) default in
the payment of any interest, including Contingent Cash Interest, under the Notes
when it becomes due and payable, and continuance of such default for a period of
thirty (30) days; (b) default in the payment of Principal Amount at Maturity,
Redemption Price, Purchase Price or Change in Control Purchase Price on any Note
when the same becomes due and payable at its Stated Maturity, upon redemption,
upon declaration, when due for purchase by the Company or otherwise; (c) failure
to comply with any of the other agreements in the Notes or the Indenture upon
the Company's receipt of notice of such default from the Trustee or from Holders
of not less than 25% in aggregate Principal Amount at Maturity of the Notes, and
its failure to cure (or obtain a waiver of) such default within 60 days after
the Company receives such notice; (d) default in the payment of principal when
due

                                     A-1-13
<PAGE>

or resulting in acceleration of other Indebtedness of the Company or any
Subsidiary for borrowed money where the aggregate principal amount with respect
to which the default or acceleration has occurred exceeds $10 million, and such
acceleration has not been rescinded or annulled or such Indebtedness repaid
within a period of 10 days after written notice to the Company by the Trustee or
to the Company and the Trustee by the Holders of at least 25% in Principal
Amount at Maturity of the Notes, provided that, if any such default or
acceleration is cured, waived, rescinded or annulled, then the Event of Default
by reason thereof would be deemed not to have occurred; and (e) certain events
of bankruptcy or insolvency. If an Event of Default occurs and is continuing,
the Trustee, or the Holders of at least 25% in aggregate Principal Amount at
Maturity of the Notes at the time outstanding, may declare all the Notes to be
due and payable immediately. Certain events of bankruptcy or insolvency are
Events of Default which will result in the Issue Price plus Original Issue
Discount and any accrued and unpaid cash interest or any Contingent Cash
Interest on the Notes becoming due and payable immediately upon the occurrence
of such Events of Default.

                  Holders of the Notes may not enforce the Indenture or the
Notes except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Notes unless it receives indemnity or security reasonably
satisfactory to it. Subject to certain limitations, Holders of a majority in
aggregate Principal Amount at Maturity of the Notes at the time outstanding may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default (except a
Default in payment of amounts specified in clause (a) or (b) above) if it
determines that withholding notice is in their interests.

16.      Subordination.

                  The payment of principal of, premium, if any, and interest,
including Contingent Cash Interest, if any, will be subordinated in right of
payment, as set forth in the Indenture, to the prior payment in full of all
Senior Indebtedness whether outstanding on the Issue Date or thereafter
incurred.

17.      Trustee Dealings with the Company.

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

18.      No Recourse Against Others.

                  A director, officer, employee, agent, representative,
stockholder or equity holder, as such, of the Company or the Trustee shall not
have any liability for any obligations of the Company or the Trustee under the
Notes or the Indenture or for any claim based on, in respect of or by reason of
such obligations or their creation. By

                                     A-1-14
<PAGE>

accepting a Note, each Holder of the Notes waives and releases all such
liability. The waiver and release are part of the consideration for the issue of
the Notes.

19.      Authentication.

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