                            -------------------------------------------------

the meanings assigned to them by such definitions.

         SECTION 1.04      Rules of Construction
                           ---------------------

         Unless the context otherwise requires:

         (a) a term has the meaning assigned to it;

         (b) an accounting term not otherwise defined has the meaning assigned
to it in accordance with GAAP;

         (c) "or" is not exclusive;

         (d) "including" means including, without limitation; and

         (e) words in the singular include the plural, and words in the plural

         SECTION 1.05      Acts of Holders
                           ---------------

         (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or
taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person
or by their agent duly appointed in writing; and, except as herein
otherwise expressly provided, such action shall become effective when such
instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments
(and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose


                                      9



of this Indenture and conclusive in favor of the Trustee and the Company, if
made in the manner provided in this Section.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to such officer the execution
thereof. Where such execution is by a signer acting in a capacity other than
such signer's individual capacity, such certificate or affidavit shall also
constitute sufficient proof of such signer's authority. The fact and date of
the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other manner which the
Trustee deems sufficient.

         The ownership of Notes shall be proved by the register for the Notes
or by a certificate of the Registrar.

         Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Note shall bind every future Holder

anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Note.

         If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company
may, at its option, by or pursuant to a resolution of the Board of Directors,
fix in advance a record date for the determination of Holders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or
other Act, but the Company shall have no obligation to do so. If such a record
date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date,
but only the Holders of record at the close of business on such record date
shall be deemed to be Holders for purposes of determining whether Holders of
the requisite proportion of outstanding Notes have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the outstanding Notes shall be
computed as of such record date; provided that no such authorization,
agreement or consent by the Holders on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this
Indenture not later than six months after the record date.

                                   ARTICLE 2

                                   THE NOTES

         SECTION 2.01      Form and Dating
                           ---------------

A-1 and A-2, which are incorporated in and made a part of this Indenture. The
terms and provisions contained in the form of Note shall constitute, and are
hereby expressly made, a part of this Indenture and to the


                                      10



extent applicable, 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. To the extent that any provision of any Note conflicts
with the express provisions of this Indenture, the provisions of this
Indenture shall govern and be controlling.

         Any of the Notes may have such letters, numbers or other marks of
identification and such notations, legends and endorsements as the officers
executing the same may approve (execution thereof to be conclusive evidence of
such approval) and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any
securities exchange or automated quotation system on which the Notes may be
listed or designated for issuance, or to conform to usage.

         (a) Global Notes in General. Each Global Note shall be deposited with
the Trustee at its Corporate Trust Office, as custodian for the Depositary and
registered in the name of The Depository Trust Company ("DTC") or the nominee
thereof (such depositary, or any successor thereto, and any such nominee being
hereinafter referred to as the "Depositary"), duly executed by the Company and
authenticated by the Trustee as hereinafter provided. Each Global Note shall
represent such of the outstanding Notes as shall be specified therein and each
shall provide that it shall represent the aggregate amount of outstanding
Notes from time to time endorsed thereon and that the aggregate amount of
outstanding Notes represented thereby may from time to time be reduced or
increased, as appropriate, to reflect exchanges, redemptions and conversions.

         Any adjustment of the aggregate principal amount of a Global Note to
reflect the amount of any increase or decrease in the amount of outstanding
Notes represented thereby shall be made by the Trustee in accordance with
instructions given by the Holder thereof as required by Section 2.12 and shall
be made on the records of the Trustee and the Depositary.

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

delivered by the Trustee to the Depositary or pursuant to the Depositary's
instructions and (c) shall bear legends substantially to the following effect:

     "UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
     THE DEPOSITORY TRUST COMPANY TO THE ISSUER OR ITS AGENT FOR REGISTRATION
     OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS
     REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
     REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY
     (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS
     IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST
     COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR


                                      11



     VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED
     OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

     TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT
     NOT IN PART, TO NOMINEES OF THE DEPOSITORY TRUST COMPANY OR TO A
     SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS
     OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH
     THE RESTRICTIONS SET FORTH IN ARTICLE TWO OF THE INDENTURE REFERRED TO ON
     THE REVERSE HEREOF."

         (c) Certificated Notes. Notes not issued as interests in the Global
Notes will be issued in certificated form substantially in the form of Exhibit
A-2 attached hereto.

         SECTION 2.02      Execution and Authentication
                           ----------------------------

         The Notes shall be executed on behalf of the Company by any Officer.
The signature of the Officer on the Notes may be manual or facsimile.

         Notes bearing the manual or facsimile signatures of individuals who
were at the time of the execution of the Notes the proper Officers of the
Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Notes or did not hold such offices at the date of
authentication of such Notes.

         No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
duly executed by the Trustee by manual signature of an authorized officer, and
such certificate upon any Note shall be conclusive evidence, and the only
evidence, that such Note has been duly authenticated and delivered hereunder.

         The Trustee shall authenticate and deliver Notes for original issue
in an aggregate principal amount of up to $65,557,000 upon a Company Order

office or agency where Notes may be presented for purchase or payment
("Paying Agent") and an office or agency where Notes may be presented for
conversion ("Conversion Agent"). The Registrar shall keep a register of the
Notes and of their transfer and exchange. The Company, upon written notice
to and approval of the Trustee, may have one or more co-registrars, one or
more additional paying agents and one or


                                      12



more additional conversion agents. The term Paying Agent includes any
additional paying agent, including any named pursuant to Section 4.05. The
term Conversion Agent includes any additional conversion agent, including any
named pursuant to Section 4.05.

         The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent, Conversion Agent or co-registrar (other than the
Trustee). The agreement shall implement the provisions of this Indenture that
relate to such agent. The Company shall notify the Trustee of the name and
address of any such agent. If the Company fails to maintain a Registrar,
Paying Agent or Conversion Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.06. The
Company or any Subsidiary or an Affiliate of either of them may act as Paying
Agent, Registrar, Conversion Agent or co-registrar.

         The Company initially appoints the Trustee as Registrar, Conversion
Agent and Paying Agent in connection with the Notes and the Trustee hereby
accepts such appointment.

         SECTION 2.04      Paying Agent to Hold Money and Notes in Trust
                           ---------------------------------------------

         Except as otherwise provided herein, on or prior to each due date of
payments in respect of any Note, the Company shall deposit with the Paying
Agent a sum of money (in immediately available funds if deposited on the due
date) sufficient to make such payments when so becoming due. The Company shall
require each Paying Agent (other than the Trustee) to agree in writing that
the Paying Agent shall hold in trust for the benefit of Noteholders or the
Trustee all money held by the Paying Agent for the making of payments in
respect of the Notes and shall notify the Trustee of any default by the
Company in making any such payment. At any time during the continuance of any
such default, the Paying Agent shall, upon the written request of the Trustee,
forthwith pay to the Trustee all money so held in trust. If the Company, a
Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall
segregate the money held by it as Paying Agent and hold it as a separate trust
fund. The Company at any time may require a Paying Agent to pay all money held
by it to the Trustee and to account for any funds disbursed by it. Upon doing
so, the Paying Agent shall have no further liability for the money.

         SECTION 2.05      Noteholder Lists
                           ----------------

Noteholders. If the Trustee is not the Registrar, the Company shall cause to
be furnished to the Trustee at least semiannually not later than 5 days after
each Regular Record Date a listing of Noteholders dated within 15 days of the
date on which the list is furnished and at such other times as the Trustee may
request in writing a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of Noteholders, and the Company
shall otherwise comply with TIA Section 312(a).

         SECTION 2.06      Transfer and Exchange
                           ---------------------

         (a) Subject to Section 2.12, upon surrender for registration of
transfer of any Note, together with a written instrument of transfer
satisfactory to the Registrar duly executed by the Noteholder or such
Noteholder's attorney duly authorized in writing, at the office or agency


                                      13



of the Company maintained pursuant to Section 2.03, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Notes of any authorized
denomination or denominations, of a like aggregate principal amount. The
Registrar or any co-registrar may require a Holder to furnish appropriate
endorsements and transfer documents. The Company shall not charge a service
charge for any registration of transfer or exchange, but the Company may
require payment of a sum sufficient to pay all taxes, assessments or other
governmental charges that may be imposed in connection with the transfer or
exchange of the Notes from the Noteholder requesting such transfer or
exchange.

         At the option of the Holder, Notes may be exchanged for other Notes
of any authorized denomination or denominations, of a like aggregate principal
amount, upon surrender of the Notes to be exchanged, together with a written
instrument of transfer satisfactory to the Registrar duly executed by the
Noteholder or such Noteholder's attorney duly authorized in writing, at such
office or agency. Whenever any Notes are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Notes which the Holder making the exchange is entitled to receive.

         The Company shall not be required to make, and the Registrar need not
register, transfers or exchanges of Notes selected for redemption (except, in
the case of Notes to be redeemed in part, the portion thereof not to be
redeemed) or any Notes in respect of which a Repurchase Notice (as defined in
Section 3.08(a)) or a Change in Control Repurchase Notice (as defined in
Section 3.09(c)) has been given and not withdrawn by the Holder thereof in
accordance with the terms of this Indenture (except, in the case of Notes to
be purchased in part, the portion thereof 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.

         (b) Notwithstanding any provision to the contrary herein, so long as
a Global Note remains outstanding and is held by or on behalf of the
Depositary, transfers of a Global Note, in whole or in part, shall be made
only in accordance with Section 2.12 and this Section 2.06(b). Transfers of a
Global Note shall be limited to transfers of such Global Note in whole, or in
part, to nominees of the Depositary or to a successor of the Depositary or
such successor's nominee.

         (c) Successive registrations and registrations of transfers and
exchanges as aforesaid may be made from time to time as desired, and each such
registration shall be noted on the register for the Notes.

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

         (e) No Registrar or co-registrar shall be required to make
registrations of transfer or exchange of Notes during any periods designated
in the text of the Notes or in this Indenture as periods during which such
registration of transfers and exchanges need not be made.


                                      14



         SECTION 2.07      Replacement Notes
                           -----------------

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

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

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

         Every new Note issued pursuant to this Section 2.07 in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

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

         SECTION 2.08      Outstanding Notes; Determinations of Holders'
                           ---------------------------------------------
                           Action
                           ------

         Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those cancelled by it or delivered to it for cancellation,
those paid pursuant to Section 2.07 and those described in this Section 2.08
as not outstanding. A Note does not cease to be outstanding because the
Company or an Affiliate thereof holds the Note; provided, however, that in
determining whether the Holders of the requisite principal amount of the
outstanding Notes have given or concurred in any request, demand,
authorization, direction, notice, consent or waiver hereunder, Notes owned by
the Company or any other obligor upon the Notes or any Affiliate of the
Company or such other obligor shall be disregarded and deemed not to be
outstanding, except that, in determining whether the Trustee shall be
protected in relying upon any such request, demand, authorization, direction,
notice, consent or waiver, only Notes which a Responsible Officer of the
Trustee knows to be so owned shall be so disregarded. Subject to the
foregoing, only Notes outstanding at the time of such determination shall be
considered in any such determination (including, without limitation,
determinations pursuant to Articles 6 and 9).


                                      15



         If a Note is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

         If the Paying Agent holds, in accordance with this Indenture, on a
Redemption Date, a Repurchase Date, a Change in Control Repurchase Date, or on
Stated Maturity, money or securities, if permitted hereunder, sufficient to
pay Notes payable on that date, then on and after such Redemption Date,
Repurchase Date, Change in Control Repurchase Date or Stated Maturity, as the
case may be, such Notes shall cease to be outstanding and interest on such
Notes shall cease to accrue; provided that, if such Notes are to be redeemed,
notice of such redemption has been duly given pursuant to this Indenture or
provision therefor satisfactory to the Trustee has been made.

         If a Note is converted in accordance with Article 10, then from and
after the time of conversion on the Conversion Date, such Note shall cease to
be outstanding and interest shall cease to accrue on such Note.

         SECTION 2.09      Temporary Notes
                           ---------------

         Pending the preparation of definitive Notes, the Company may execute,
and upon Company Order the Trustee shall authenticate and deliver, temporary
Notes which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Notes in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the Officers
executing such Notes may determine, as conclusively evidenced by their
execution of such Notes.

         If temporary Notes are issued, the Company will cause definitive
Notes to be prepared without unreasonable delay. After the preparation of
definitive Notes, the temporary Notes shall be exchangeable for definitive
Notes upon surrender of the temporary Notes at the office or agency of the
Company designated for such purpose pursuant to Section 2.03, without charge
to the Holder. Upon surrender for cancellation of any one or more temporary
Notes the Company shall execute and the Trustee shall authenticate and deliver
in exchange therefor a like principal amount of definitive Notes of authorized
denominations. Until so exchanged the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as definitive Notes.

         SECTION 2.10      Cancellation
                           ------------

         All Notes surrendered for payment, purchase by the Company
pursuant to Article 3, conversion, redemption or registration of transfer
or exchange shall, if surrendered to any person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Notes
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Notes so delivered shall be
promptly cancelled by the Trustee. The Company may not issue new Notes to
replace Notes it has paid or delivered to the Trustee for cancellation or
that any Holder has converted pursuant to Article 10. No Notes shall be


                                      16



authenticated in lieu of or in exchange for any Notes cancelled as provided in
this Section 2.10, except as expressly permitted by this Indenture. All
cancelled Notes held by the Trustee shall be destroyed by the Trustee and the
Trustee shall deliver a certificate of destruction to the Company.

         SECTION 2.11      Persons Deemed Owners
                           ---------------------

         Prior to due presentment of a Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Note is registered as the owner of such Note for the
purpose of receiving payment of principal of the Note or the payment of any
Redemption Price, Repurchase Price or Change in Control Repurchase Price in
respect thereof, and interest thereon, for the purpose of conversion and for
all other purposes whatsoever, whether or not such Note be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

         SECTION 2.12      Global Notes

         (a) Notwithstanding any other provisions of this Indenture or the
Notes, (A) transfers of a Global Note, in whole or in part, shall be made only
in accordance with Section 2.06 and Section 2.12(a)(i), (B) transfer of a
beneficial interest in a Global Note for a Certificated Note shall comply with
Section 2.06 and Section 2.12(a)(ii) below, and (C) transfers of a
Certificated Note shall comply with Section 2.06 and Section 2.12(a)(iii) and
(iv) below.

         (i) Transfer of Global Note. A Global Note may not be transferred, in
     whole or in part, to any Person other than the Depositary or a nominee or
     any successor thereof, and no such transfer to any such other Person may
     be registered; provided that this clause (i) shall not prohibit any
     transfer of a Note that is issued in exchange for a Global Note but is
     not itself a Global Note. No transfer of a Note to any Person shall be
     effective under this Indenture or the Notes unless and until such Note
     has been registered in the name of such Person. Nothing in this Section
     2.12(a)(i) shall prohibit or render ineffective any transfer of a
     beneficial interest in a Global Note effected in accordance with the
     other provisions of this Section 2.12(a).

         (ii) Restrictions on Transfer of a Beneficial Interest in a Global
     Note for a Certificated Note. A beneficial interest in a Global Note may
     not be exchanged upon transfer for a Certificated Note except upon
     satisfaction of the requirements set forth below. Upon receipt by the
     Trustee of a request for transfer of a beneficial interest in a Global
     Note in accordance with Applicable Procedures for a Certificated Note in
     the form satisfactory to the Trustee, together with written instructions
     to the Trustee to make, or direct the Registrar to make, an adjustment on
     its books and records with respect to such Global Note to reflect a
     decrease in the aggregate principal amount of the Notes represented by
     the Global Note, such instructions to contain information regarding the
     Depositary account to be credited with such decrease, then the Trustee
     shall cause, or direct the Registrar to cause, in accordance with the
     standing instructions and procedures existing between the Depositary and
     the Registrar, the aggregate principal amount of Notes represented by the
     Global Note to be decreased by the aggregate principal amount


                                      17



     of the Certificated Note to be issued, shall issue such Certificated Note
     and shall debit or cause to be debited to the account of the Person
     specified in such instructions a beneficial interest in the Global Note
     equal to the principal amount of the Certificated Note so issued.

         (iii) Transfer and Exchange of Certificated Notes. When Certificated
     Notes are presented to the Registrar with a request:

               (x) to register the transfer of such Certificated Notes; or

               (y) to exchange such Certificated Notes for an equal principal
         amount of Certificated Notes of other authorized denominations,

     the Registrar shall register the transfer or make the exchange as
     requested if its reasonable requirements for such transaction are met;
     provided, however, that the Certificated Notes surrendered for transfer
     or exchange shall be duly endorsed or accompanied by a written instrument
     of transfer in form reasonably satisfactory to the Company and the
     Registrar, duly executed by the Holder thereof or his attorney duly
     authorized in writing.

         (iv) Restrictions on Transfer of a Certificated Note for a Beneficial
     Interest in a Global Note. A Certificated Note may not be exchanged for a
     beneficial interest in a Global Note except upon satisfaction of the
     requirements set forth below.

     Upon receipt by the Trustee of a Certificated Note, duly endorsed or
     accompanied by appropriate instruments of transfer, in form satisfactory
     to the Trustee, together with written instructions directing the Trustee
     to make, or to direct the Registrar to make, an adjustment on its books
     and records with respect to such Global Note to reflect an increase in
     the aggregate principal amount of the Notes represented by the Global
     Note, such instructions to contain information regarding the Depositary
     account to be credited with such increase, then the Trustee shall cancel
     such Certificated Note and cause, or direct the Registrar to cause, in
     accordance with the standing instructions and procedures existing between
     the Depositary and the Registrar, the aggregate principal amount of Notes
     represented by the Global Note to be increased by the aggregate principal
     amount of the Certificated Note to be exchanged, and shall credit or
     cause to be credited to the account of the Person specified in such
     instructions a beneficial interest in the Global Note equal to the
     principal amount of the Certificated Note so cancelled. If no Global
     Notes are then outstanding, the Company shall issue and the Trustee shall
     authenticate, upon written order of the Company in the form of an
     Officers' Certificate, a new Global Note in the appropriate principal
     amount.

         (b) The provisions of clauses (1), (2), (3) and (4) below shall apply
only to Global Notes:

         (1) Notwithstanding any other provisions of this Indenture or the
     Notes, except as provided in Section 2.12(a)(ii), a Global Note shall not
     be exchanged in whole or in part for a Note registered in the name of any
     Person other than the Depositary or one or more nominees thereof,
     provided that a Global Note may be exchanged for Notes registered in


                                      18



     the name of any person designated by the Depositary in the event that (i)
     the Depositary has notified the Company that it is unwilling or unable to
     continue as Depositary for such Global Note or such Depositary has ceased
     to be a "clearing agency" registered under the Exchange Act, and a
     successor Depositary is not appointed by the Company within 90 days of
     either event or (ii) an Event of Default has occurred and is continuing
     with respect to the Notes. Any Global Note exchanged pursuant to clause
     (i) above shall be so exchanged in whole and not in part, and any Global
     Note exchanged pursuant to clause (ii) above may be exchanged in whole or
     from time to time in part as directed by the Depositary. Any Note issued
     in exchange for a Global Note or any portion thereof shall be a Global
     Note; provided that any such Note so issued that is registered in the
     name of a Person other than the Depositary or a nominee thereof shall not
     be a Global Note.

         (2) Notes issued in exchange for a Global Note or any portion thereof
     shall be issued in definitive, fully registered form, without interest
     coupons, shall have an aggregate principal amount equal to that of such
     Global Note or portion thereof to be so exchanged, shall be registered in
     such names and be in such authorized denominations as the Depositary
     shall designate. Any Global Note to be exchanged in whole shall be
     surrendered by the Depositary to the Trustee, as Registrar. With regard
     to any Global Note to be exchanged in part, either such Global Note shall
     be so surrendered for exchange or, if the Trustee is acting as custodian
     for the Depositary or its nominee with respect to such Global Note, the
     principal amount thereof shall be reduced, by an amount equal to the
     portion thereof to be so exchanged, by means of an appropriate adjustment
     made on the records of the Trustee. Upon any such surrender or
     adjustment, the Trustee shall authenticate and deliver the Note issuable
     on such exchange to or upon the order of the Depositary or an authorized
     representative thereof.

         (3) Subject to the provisions of clause (5) below, the Holder may
     grant proxies and otherwise authorize any Person, including Agent Members
     (as defined below) and persons that may hold interests through Agent
     Members, to take any action which a Holder is entitled to take under this
     Indenture or the Notes.

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

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


                                      19



     Agent Member may act, the operation of customary practices of such
     Persons governing the exercise of the rights of a Holder of any Note.

         SECTION 2.13      CUSIP Numbers
                           -------------

         The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such
notice may state that no representation is made as to the correctness of such
numbers either as printed on the Notes or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Notes, and any such redemption shall not be affected by
any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any change in the CUSIP numbers.

         SECTION 2.14      Defaulted Interest
                           ------------------

         If the Company defaults in a payment of interest on the Notes, it
shall pay, or shall deposit with the Paying Agent money in immediately
available funds sufficient to pay, the defaulted interest, plus (to the extent
lawful) any interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date. A special record date, as used in
this Section 2.14 with respect to the payment of any defaulted interest, shall
mean the 15th day next preceding the date fixed by the Company for the payment
of defaulted interest, whether or not such day is a Business Day. At least 15
days before the subsequent special record date, the Company shall mail to each
Holder and to the Trustee a notice that states the subsequent special record
date, the payment date and the amount of defaulted interest to be paid.

                                  ARTICLE 3

                           REDEMPTION AND PURCHASES

               SECTION 3.01       Right to Redeem; Notices to Trustee
                                  -----------------------------------

         The Company, at its option, may redeem the Notes in accordance with
the provisions of paragraphs 5 and 7 of the Notes. If the Company elects to
redeem Notes pursuant to paragraph 5 of the Notes, it shall notify the Trustee
in writing of the Redemption Date, the principal amount of Notes to be
redeemed and the Redemption Price.

         The Company shall give the notice to the Trustee provided for in this
Section 3.01 by a Company Order, at least 45 days before the Redemption Date
(unless a shorter notice shall be satisfactory to the Trustee).

         SECTION 3.02      Selection of Notes to Be Redeemed
                           ---------------------------------

         If less than all the 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 stock exchange on which the Notes are then
listed). The Trustee shall make the selection at least 15 days but not more
than 60 days before the Redemption Date from outstanding Notes not
previously called for redemption. The


                                      20



Trustee may select for redemption portions of the principal amount of Notes
that have denominations equal to or larger than $1,000.

         Notes and portions of Notes the Trustee selects shall be in principal
amounts of $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to Notes called for redemption also apply to portions of
Notes called for redemption. The Trustee shall notify the Company promptly 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 3.03      Notice of Redemption
                           --------------------

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

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

         (1) the Redemption Date;

         (2) the Redemption Price;

         (3) the Conversion Price;

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

         (5) that Notes called for redemption may be surrendered for
     conversion at any time before the close of business on the Business Day
     immediately preceding the Redemption Date;

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

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

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

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

         (10) the CUSIP number of the Notes.


                                      21



         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense, provided that
the Company makes such request at least three Business Days prior to the date
of such notice of redemption.

         SECTION 3.04      Effect of Notice of Redemption
                           -------------------------------

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

         SECTION 3.05      Deposit of Redemption Price
                           ---------------------------

         Prior to 10:00 a.m. (New York City time) on the Redemption Date, the
Company shall deposit with the Paying Agent (or if the Company or a Subsidiary
or an Affiliate of either of them is the Paying Agent, shall segregate and
hold in trust) money sufficient to pay the Redemption Price of 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, with interest, if
any, thereon, not required for that purpose because of conversion of Notes
pursuant to Article 10. 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 3.06      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 to the unredeemed
portion of the Note surrendered.

         SECTION 3.07      Conversion Arrangement on Call for Redemption
                           ---------------------------------------------

         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 Noteholders, 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 such
Notes. Notwithstanding anything to the contrary contained in this Article 3,
the obligation of the Company to pay the Redemption Price 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, to be acquired by
such purchasers from such Holders and (notwithstanding anything to the
contrary contained in Article 10) surrendered by such purchasers for
conversion, all as of immediately prior to the close of business on 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


                                      22



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 3.08      Repurchase of Notes at the Option of the Holder
                           -----------------------------------------------

         (a) If a Holder exercises its right to require the Company to
repurchase the Notes, the Notes shall be repurchased by the Company on March
19, 2007, March 19, 2012, and March 19, 2017 (each, a "Repurchase Date"), at
the purchase price of 100% of the principal amount of the Notes to be
repurchased, together with interest accrued and unpaid to, but excluding, the
Repurchase Date (the "Repurchase Price"), at the option of the Holder thereof,
upon:

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

         conversion or exchange of outstanding Common Shares solely into
         common shares of the surviving entity.

         (b) Unless the Company shall have theretofore called for redemption
all of the outstanding Notes, prior to or on the 30th day after the occurrence

     payment;

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

         The delivery of such Note to the Paying Agent prior to, on or after

     by the Company; and

         (4) that such Repurchase Notice or Change in Control Repurchase
     Notice is being withdrawn.

Change in Control Repurchase Notice) and is continuing an Event of Default
(other than a default in the payment of the Repurchase Price or Change in
Control Repurchase Price, as the case may be, with respect to such Notes). The

Control Repurchase Price, as the case may be, with respect to such Notes) in
which case, upon such return, the Repurchase Notice or Change in Control
Repurchase Notice, as the case may be, with respect thereto shall be deemed to

     substantially as an entirety (i) shall be organized and validly existing
     under the laws of the United States or any State thereof or the District
     of Columbia and (ii) shall expressly assume, by an indenture supplemental
     hereto, executed and delivered to the Trustee, in form satisfactory to
     the Trustee, all of the obligations of the Company under the Notes and
     this Indenture;

         (b) at the time of such transaction, no Event of Default and no event
     which, after notice or lapse of time, would become an Event of Default,
     shall have happened and be continuing; and

         (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 5 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 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 under this Indenture with the same
effect as if such successor had been named as the Company herein; and
thereafter, except in the case of a lease and obligations the Company may have
under a supplemental indenture pursuant to Section 10.11, the Company shall be
discharged from all obligations and covenants under this Indenture and the
Notes. Subject to Section 9.06, the Company, the Trustee and the successor
person shall enter into a supplemental indenture to evidence the succession
and substitution of such successor person and such discharge and release of
the Company.

         (5) (A) one or more defaults in the payment of principal of or
     premium, if any, on any of the Company's Indebtedness aggregating $10

     such acceleration;

         (6) a failure to provide timely notice of a Change in Control;

         (7) the Company, or any Significant Subsidiary, or any Subsidiaries

         "Bankruptcy Law" means Title 11, United States Code, or any similar
federal or state law for the relief of debtors, including without limitation
state laws relating to insolvency, liquidation, rehabilitation or receivership
of insurance companies.

         "Custodian" means any receiver, trustee, assignee, liquidator,
rehabilitator, custodian or similar official under any Bankruptcy Law.

         A Default under clause (4) above is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in aggregate
principal amount of the Notes at the time outstanding notify the Company and
the Trustee, of the Default and the Company does not cure such Default (and
such Default is not waived) within the time specified in clause (4) above
after actual receipt of such notice. Any such notice must specify the Default,
demand that it be remedied and state that such notice is a "Notice of
Default".

         The Company will deliver to the Trustee, within five Business Days of
becoming aware of the occurrence of an Event of Default, written notice
thereof. In addition, the Company shall deliver to the Trustee, within 30 days
after it becomes aware of the occurrence thereof, written notice of any event
which with the lapse of time would become an Event of Default under clause (4)
above, its status and what action the Company is taking or proposes to take
with respect thereto.


                                      34



         SECTION 6.02      Acceleration
                           ------------

         If an Event of Default (other than an Event of Default specified in
Section 6.01(7) or (8)) occurs and is continuing, the Trustee by notice to the
Company, or the Holders of at least 25% in aggregate principal amount of the
Notes at the time outstanding by notice to the Company and the Trustee, may
declare all of the outstanding Notes immediately due and payable at their
principal amount together with accrued interest. Upon such declaration of
acceleration, such principal and accrued and unpaid interest to the date of
payment shall be immediately due and payable.

         If an Event of Default specified in Section 6.01(7) or (8) above
occurs and is continuing, then the principal and the 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 Noteholders.

         The Holders of a majority in aggregate principal amount of the Notes
at the time outstanding, by written notice to the Trustee (and without notice
to any other Noteholder) may rescind or annul an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of the principal and any accrued cash interest that have become due
solely as a result of acceleration and if all amounts due to the Trustee under
Section 7.06 have been paid. No such rescission shall affect any subsequent
Default or impair any right consequent thereto.

         SECTION 6.03      Other Remedies
                           --------------

         If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of the principal, the
premium, if any, and any accrued cash interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

         The Trustee may maintain a proceeding even if the Trustee does not
possess any of the Notes or produce any of the Notes in the proceeding. A
delay or omission by the Trustee or any Noteholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of, or acquiescence in, the Event of Default. No remedy
is exclusive of any other remedy. All available remedies are cumulative.

         SECTION 6.04      Waiver of Past Defaults
                           -----------------------

         The Holders of a majority in aggregate principal amount of the Notes
at the time outstanding through their written consent, by notice to the
Trustee (and without notice to any other Noteholder), may waive an existing
Default and its consequences except (1) an Event of Default described in
Section 6.01(1) or (2), (2) a Default in respect of a provision that under
Section 9.02 cannot be amended without the consent of each Noteholder affected
or (3) a Default which constitutes a failure to convert any Note in accordance
with the terms of Article 10. When a Default is waived, it is deemed cured,
but no such waiver shall extend to any subsequent or other Default or impair
any consequent right. This Section 6.04 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.


                                      35



         SECTION 6.05      Control by Majority
                           -------------------

         The Holders of a majority in aggregate principal amount of the Notes
at the time outstanding may direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or of exercising any
trust or power conferred on the Trustee. However, the Trustee may refuse to
follow any direction that conflicts with law or this Indenture or that the
Trustee determines in good faith is unduly prejudicial to the rights of other
Noteholders or would involve the Trustee in personal liability unless the
Trustee is offered indemnity satisfactory to it against loss, liability or
expense. This Section 6.05 shall be in lieu of Section 316(a)1(A) of the TIA
and such Section 316(a)1(A) is hereby expressly excluded from this Indenture,
as permitted by the TIA.

         SECTION 6.06      Limitation on Suits
                           -------------------

         A Noteholder may not pursue any remedy with respect to this Indenture
or the Notes unless:

         (1) the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

         (2) the Holders of at least 25% in aggregate principal amount of the
     Notes at the time outstanding make a written request to the Trustee to
     pursue the remedy;

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

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

         (5) the Holders of a majority in aggregate principal amount of the
     Notes at the time outstanding do not give the Trustee a direction
     inconsistent with the request during such 60-day period.

         A Noteholder may not use this Indenture to prejudice the rights of
any other Noteholder or to obtain a preference or priority over any other
Noteholder, except in the manner provided in this Indenture.

         SECTION 6.07      Rights of Holders to Receive Payment
                           ------------------------------------

         Notwithstanding any other provision of this Indenture, the right of
any Holder to receive payment of the principal amount, premium, if any, plus
Redemption Price, Repurchase Price, Change in Control Repurchase Price or any
accrued cash interest 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 10, 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 consent of
such Holder.

                                      36



         SECTION 6.08      Collection Suit by Trustee
                           --------------------------

         If an Event of Default described in Section 6.01(1) or (2) occurs and
is continuing, the Trustee may recover judgment in its own name and as trustee
of an express trust against the Company for the whole amount owing with
respect to the Notes and the amounts provided for in Section 7.06.

         SECTION 6.09      Trustee May File Proofs of Claim
                           --------------------------------

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Notes or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal amount,
Repurchase Price, Redemption Price, Change in Control Repurchase Price or any
accrued cash interest in respect of the Notes shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand on the Company for the payment of any
such amount) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

         (a) to file and prove a claim for the whole amount of the principal
amount, Repurchase Price, Redemption Price, Change in Control Repurchase Price
or any accrued cash interest and to file such other papers or documents as may
be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel or any other amounts due
the Trustee under Section 7.06) and of the Holders allowed in such judicial
proceeding, and

         (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 7.06.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

         SECTION 6.10      Priorities
                           ----------

         If the Trustee collects any money pursuant to this Article 6, it
shall pay out the money in the following order:

         (1) to the Trustee for amounts due under Section 7.06;

         (2) to Noteholders for amounts due and unpaid on the Notes for the
     principal amount, Redemption Price, Repurchase Price, Change in Control
     Purchase Price or any


                                      37



     accrued cash interest as the case may be, ratably, without preference or
     priority of any kind, according to such amounts due and payable on the
     Notes; and

         (3) the balance, if any, to the Company.

         The Trustee may fix a record date and payment date for any payment to
Noteholders pursuant to this Section 6.10. At least 15 days before such record
date, the Trustee shall mail to each Noteholder and the Company a notice that
states the record date, the payment date and the amount to be paid.

         SECTION 6.11      Undertaking for Costs
                           ---------------------

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted
by it as Trustee, a court in its discretion may require the filing by any
party litigant (other than the Trustee) in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not
apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or
a suit by Holders of more than 10% in aggregate principal amount of the Notes
at the time outstanding. This Section 6.11 shall be in lieu of Section 315(e)
of the TIA and such Section 315(e) is hereby expressly excluded from this
Indenture, as permitted by the TIA.

         SECTION 6.12      Waiver of Stay, Extension or Usury Laws
                           ---------------------------------------

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law or any
usury or other law wherever enacted, now or at any time hereafter in force,
which would prohibit or forgive the Company from paying all or any portion of
the principal amount, Redemption Price, Repurchase Price, Change in Control
Repurchase Price or any accrued cash interest in respect of Notes, or any
interest on such amounts, as contemplated herein, or which may affect the
covenants or the performance of this Indenture; and the Company (to the extent
that it may lawfully do so) hereby expressly waives all benefit or advantage
of any such law, and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been
enacted.

                                  ARTICLE 7

                                   TRUSTEE


         SECTION 7.01      Duties and Responsibilities of the Trustee; During
                           --------------------------------------------------
Default; Prior to Default
- -------------------------

         The Trustee, prior to the occurrence of an Event of Default
hereunder and after the curing or waiving of all such Events of Default
which may have occurred, undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture. In case an


                                      38



Event of Default hereunder has occurred (which has not been cured or waived),
the Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

         No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that

         (a) prior to the occurrence of an Event of Default hereunder and
after the curing or waiving of all such Events of Default which may have
occurred:

               (i) the duties and obligations of the Trustee shall be
         determined solely by the express provisions of this Indenture, and
         the Trustee shall not be liable except for the performance of such
         duties and obligations as are specifically set forth in this
         Indenture, and no implied covenants or obligations shall be read into
         this Indenture against the Trustee; and

               (ii) in the absence of bad faith on the part of the Trustee,
         the Trustee may conclusively rely, as to the truth of the statements
         and the correctness of the opinions expressed therein, upon any
         statements, certificates or opinions furnished to the Trustee and
         conforming to the requirements of this Indenture; but in the case of
         any such statements, certificates or opinions which by any provision
         hereof are specifically required to be furnished to the Trustee, the
         Trustee shall be under a duty to examine the same to determine
         whether or not they conform to the requirements of this Indenture;

         (b) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer or Responsible Officers of the
     Trustee, unless it shall be proved that the Trustee was negligent in
     ascertaining the pertinent facts; and

         (c) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the
     direction of the Holders pursuant to Section 6.05 relating to the time,
     method and place of conducting any proceeding for any remedy available to
     the Trustee, or exercising any trust or power conferred upon the Trustee,
     under this Indenture.

         None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable grounds for believing that
the repayment of such funds or adequate indemnity against such liability is
not reasonably assured to it. Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the
provisions of this Section 7.01.

         The provisions of this Section 7.01 are in furtherance of and subject
to Sections 315 and 316 of the TIA.


                                      39



         SECTION 7.02      Certain Rights of the Trustee
                           -----------------------------

         In furtherance of and subject to the TIA and subject to Section 7.01:

         (a) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, Officers' Certificate or any other
certificate, statement, instrument, opinion, report, direction, notice,
request, consent, order, bond, debenture, note, coupon, Note or other paper or
document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

         (b) any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by a Company Request or an Officers'
Certificate (unless other evidence in respect thereof be herein specifically
prescribed); and any resolution of the Board of Directors may be evidenced to
the Trustee by a copy thereof certified by the secretary or an assistant
secretary of the Company;

         (c) the Trustee may consult with counsel of its selection and any
advice or Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted to be taken by
it hereunder in good faith and in accordance with such advice or Opinion of
Counsel;

         (d) the Trustee shall be under no obligation to exercise any of the
rights, trusts or powers vested in it by this Indenture with the request,
order or direction of any of the Noteholders pursuant to the provisions of
this Indenture, unless such Noteholders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred therein or thereby;

         (e) the Trustee shall not be liable for any action taken or omitted
by it in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it by this Indenture;

         (f) prior to the occurrence of an Event of Default hereunder and
after the curing or waiving of all such Events of Default, the Trustee shall
not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, appraisal, bond, debenture, note, coupon,
security, or other paper or document unless requested in writing to do so by
the Holders of not less than a majority in aggregate principal amount of the
Notes then outstanding; provided that, if the payment within a reasonable time
to the Trustee of the costs, expenses or liabilities likely to be incurred by
it in the making of such investigation is, in the opinion of the Trustee, not
reasonably assured to the Trustee by the security afforded to it by the terms
of this Indenture, the Trustee may require reasonable indemnity against such
costs, expenses or liabilities as a condition to proceeding; the reasonable
costs, expenses and liabilities of every such investigation shall be paid by
the Company or, if paid by the Trustee or any predecessor trustee, shall be
repaid by the Company upon demand; and

         (g) the Trustee may execute any of the trusts or powers hereunder

by it hereunder.

         The recitals contained herein and in the Notes, except the Trustee's

         The Trustee or any agent of the Company or the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Notes

         Subject to the provisions of Section 8.02, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for

                           ---------------------------------------------------
Prior Claim
- -----------

         The Company covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, such compensation (which shall not
be limited by any provision of law in regard to the compensation of a trustee
of an express trust) to be agreed to in writing by the Trustee and the Company,
and the Company covenants and agrees to pay or reimburse the Trustee and each
predecessor Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by or on behalf of it in accordance with any of
the provisions of this Indenture (including (i) the reasonable compensation and
the expenses and disbursements of its counsel and of all agents and other
persons not regularly in its employ and (ii) interest at the prime rate on any
disbursements and advances made by the Trustee and not paid by the Company
within 15 days after receipt of an invoice for such disbursement or advance)
except any such expense, disbursement or advance as may arise from its

and each predecessor Trustee for, and to hold it harmless against, any loss,
liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of this
Indenture or the trusts hereunder and its duties hereunder, including the costs

liability in the premises. As security for the performance of


                                      41



the obligations of the Company under this Section, the Trustee shall have a
lien prior to the Notes upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the benefit of the Holders of
particular Notes, and the Notes are hereby effectively subordinated to such
senior claim to such extent. The provisions of this Section 7.06 shall survive
the termination of this Indenture.

         Subject to Sections 7.01 and 7.02, whenever in the administration of
the trusts of this Indenture the Trustee shall deem it necessary or desirable
that a matter be proved or established prior to taking or suffering or
omitting any action hereunder, such matter (unless other evidence in respect
thereof be herein specifically prescribed) may, in the absence of negligence
or bad faith on the part of the Trustee, be deemed to be conclusively proved
and established by an Officers' Certificate delivered to the Trustee, and such
certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered
or omitted by it under the provisions of this Indenture upon the faith
thereof.

         SECTION 7.08      Conflicting Interests
                           ---------------------

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the TIA, the Trustee shall either eliminate such interest or
resign, to the extent and in the manner provided by, and subject to the
provisions of, the TIA.

         SECTION 7.09      Persons Eligible for Appointment as Trustee

         The Trustee shall at all times be a corporation or banking
association having a combined capital and surplus of at least $50,000,000 and
otherwise meeting the requirements for eligibility as a trustee in the TIA. If
such corporation or banking association publishes reports of condition at
least annually, pursuant to law or to the requirements of the supervising or
examining authority, then, for the purposes of this Section 7.09, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.09, the Trustee shall resign
immediately in the manner and with the effect specified in Section 7.10.

         SECTION 7.10      Resignation and Removal; Appointment of Successor
                           -------------------------------------------------
Trustee
- -------

         (a) The Trustee, or any trustee or trustees hereafter appointed,
may at any time resign with respect to the Notes by giving written notice
of resignation to the Company and by mailing notice thereof by first class
mail to the Holders of Notes at their last addresses as they shall appear
on the Note register. Upon receiving such notice of resignation, the
Company shall promptly appoint a successor trustee or trustees by written
instrument in duplicate, executed by authority of the Board of Directors,
one copy of which instrument shall be delivered to the resigning Trustee
and one copy to the successor trustee or trustees. If no successor trustee
shall have been so appointed and have accepted appointment within 30 days
after the mailing of such notice of resignation, the resigning trustee may
petition any court of competent jurisdiction for


                                      42



the appointment of a successor trustee, or any Noteholder who has been a bona
fide Holder of a Note for at least six months may, subject to the provisions
of Section 7.11, on behalf of himself and all others similarly situated,
petition any such court for the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

         (b) In case at any time any of the following shall occur:

         (i) the Trustee shall fail to comply with the provisions of Section
     7.08 with respect to any Notes after written request therefor by the
     Company or by any Noteholder who has been a bona fide Holder of a Note
     for at least six months; or

         (ii) the Trustee shall cease to be eligible in accordance with the
     provisions of Section 7.09 and shall fail to resign after written request
     therefor by the Company or by any Noteholder; or

         (iii) the Trustee shall become incapable of acting or shall be
     adjudged a bankrupt or insolvent, or a receiver or liquidator of the
     Trustee or of its property shall be appointed, or any public officer
     shall take charge or control of the Trustee or of its property or affairs
     for the purpose of rehabilitation, conservation or liquidation; or

         (iv) the Company shall determine in good faith that the Trustee has
     failed to perform its obligations under this Indenture in any material
     respect;

then, in any such case, the Company by Board Resolution may remove the Trustee
and appoint a successor trustee by written instrument, in duplicate, executed
by order of the Board of Directors of the Company, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the
successor trustee, or, subject to the provisions of Section 7.11, any
Noteholder who has been a bona fide Holder of a Note for at least six months
may on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee and the appointment
of a successor trustee. Such court may thereupon, after such notice, if any,
as it may deem proper and prescribe, remove the Trustee and appoint a
successor trustee. If no successor trustee shall have been appointed and have
accepted appointment within 30 days after a notice of removal has been given,
the removed trustee may petition a court of competent jurisdiction for the
appointment of a successor trustee.

         (c) The Holders of a majority in aggregate principal amount of the
Notes at the time outstanding may at any time remove the Trustee and appoint a
successor trustee by delivering to the Trustee so removed, to the successor
trustee so appointed and to the Company the evidence provided for in Section
1.05 of the action in that regard taken by the Noteholders.

         (d) Any resignation or removal of the Trustee and any appointment of
a successor trustee pursuant to any of the provisions of this Section 7.10
shall become effective upon acceptance of appointment by the successor trustee
as provided in Section 7.11.


                                      43



         SECTION 7.11      Acceptance of Appointment by Successor Trustee
                           ----------------------------------------------

         Any successor trustee appointed as provided in Section 7.10 shall
execute and deliver to the Company and to its predecessor trustee an
instrument accepting such appointment hereunder, and thereupon the resignation
or removal of the predecessor trustee shall become effective and such
successor trustee, without any further act, deed or conveyance, shall become
vested with all rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as trustee hereunder; but,
nevertheless, on the written request of the Company or of the successor
trustee, upon payment of its charges then unpaid, the trustee ceasing to act
shall duly assign, transfer and deliver to the successor trustee all property
and moneys at the time held by it hereunder and shall execute and deliver an
instrument transferring to such successor trustee all such rights, powers,
duties and obligations held by such retiring Trustee hereunder, subject
nevertheless to its lien, if any, provided for in Section 7.06. Upon request
of any such successor trustee, the Company shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming
to such successor trustee all such rights and powers. Any trustee ceasing to
act shall, nevertheless, retain a prior claim upon all property or funds held
or collected by such trustee to secure any amounts then due it pursuant to the
provisions of Section 7.06.

         No successor trustee shall accept appointment as provided in this
Section 7.11 unless at the time of such acceptance such successor trustee
shall be qualified under the provisions of Section 7.08 and eligible under the
provisions of Section 7.09.

         Upon acceptance of appointment by any successor trustee as provided
in this Section 7.11, the Company shall mail notice thereof by first class
mail to the Holders of Notes at their last addresses as they shall appear in
the register. If the acceptance of appointment is substantially
contemporaneous with the resignation, then the notice called for by the
preceding sentence may be combined with the notice called for by Section 7.10.
If the Company fails to mail such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

         SECTION 7.12      Merger, Conversion, Consolidation or Succession to
                           --------------------------------------------------
Business of Trustee
- -------------------

         Any corporation or banking association into which the Trustee may be
merged or converted or with which it may be consolidated, or any corporation
or banking association resulting from any merger, conversion or consolidation
to which the Trustee shall be a party, or any corporation or banking
association succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation or banking association shall be qualified under
the provisions of Section 7.08 and eligible under the provisions of Section
7.09, without the execution or filing of any paper or any further act on the
part of any of the parties hereto, anything herein to the contrary
notwithstanding. In case at the time such successor to the Trustee shall
succeed to the trusts created by this Indenture any of the Notes shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Notes so authenticated; and, in case at that time any of the Notes shall
not have been authenticated, any successor to the Trustee may authenticate
such Notes either in the name of any predecessor hereunder or in the name of
the successor Trustee; and in all such cases such certificate shall have the
full force and effect that this Indenture provides for the


                                      44



certificate of authentication of the Trustee; provided, that the right to
adopt the certificate of authentication of any predecessor Trustee or to
authenticate Notes in the name of any predecessor Trustee shall apply only to
its successor or successors by merger, conversion or consolidation.

         SECTION 7.13      Preferential Collection of Claims Against the Company
                           -----------------------------------------------------

TIA.

         SECTION 7.14      Reports by the Trustee
                           ----------------------

         (a) The Trustee shall transmit to Holders and other persons such
reports concerning the Trustee and its actions under this Indenture as may be
required pursuant to the TIA at such times as any such report may be required
by the TIA on or before July 15 in each year that such report is required,
such reports to be dated as of the immediately preceding May 15. The Trustee
also shall comply with TIA Section 313, as applicable.

         (b) A copy of each such report shall, at the time of such
transmission to Noteholders, be furnished to the Company and be filed by the
Trustee with each stock exchange upon which the Notes are listed and also with
the SEC. The Company agrees to notify the Trustee when and as the Notes become
admitted to trading on any national securities exchange or automated
inter-dealer quotation system.

         SECTION 7.15      Trustee to Give Notice of Default, But May Withhold
                           ---------------------------------------------------
in Certain Circumstances
- ------------------------

         The Trustee shall transmit to the Noteholders, as the names and
addresses of such Holders appear on the Note register, notice by mail of all
Defaults which have occurred, such notice to be transmitted within 90 days
after the occurrence thereof, unless such Defaults shall have been cured
before the giving of such notice; provided that, except in the case of Default
in the payment of the principal of, interest on, or other similar obligation
with respect to, any of the Notes, 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 trustees and/or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the best interests of the Noteholders.

         If (i) all outstanding Notes will become due and payable at their
Stated Maturity within one year; or (ii) all outstanding Notes are
scheduled for redemption within one year; and, in either case, the Company
deposits with the Trustee cash sufficient to pay and discharge all amounts
due and owing on all outstanding Notes (other than Notes replaced pursuant
to Section 2.07) on the date of their Stated Maturity or on the date of
their scheduled redemption, and if in


                                      45



either case the Company pays all other sums payable hereunder by the Company,
then this Indenture shall, subject to Section 7.06 and provided that the
Company shall remain obligated to deliver the Principal Return and Net Shares,
if any, upon conversion of the Notes as provided in Article 10 of this
Indenture, 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 demand of the Company accompanied by an
Officers' Certificate and Opinion of Counsel and at the cost and expense of
the Company.

         SECTION 8.02      Repayment of the Company

         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 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 Noteholders with respect to such money or securities for that
period commencing after the return thereof.

Actions
- -------

         Until an amendment, waiver or other action by Holders becomes

supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so

to the provisions of Section 7.01) shall be fully protected in relying upon,
an Officers' Certificate and an Opinion of Counsel stating that such amendment
is authorized or permitted by this Indenture.

                                  CONVERSION

         SECTION 10.01      Conversion Right and Conversion Price
                            -------------------------------------

         Subject to and upon compliance with the provisions of this Article
10, at the option of the Holder thereof, any Note or any portion of the
principal amount thereof which is $1,000 or an integral multiple of $1,000 may
be converted at any time during the periods and subject to the conditions
stated in paragraph 8 of the Notes at the principal amount thereof, or of such
portion thereof, at the Conversion Price determined as hereinafter provided,
in effect at the time of conversion, into (a) cash in an amount (the
"Principal Return") equal to the lesser of (1) the principal amount of such
Note or (2) the Conversion Value (as described below); and (b) a number of
duly authorized, fully paid and nonassessable Common Shares (the "Net Shares")
equal to the sum of the Daily Share Amounts (calculated as described below)
for each of the thirty consecutive trading days in the Applicable Conversion
Reference Period (as defined below), provided, however, that cash will be paid
in lieu of fractional shares otherwise issuable upon conversion of a Note.

         The "Conversion Value" is equal to (1) the Conversion Rate,
multiplied by (2) the average of the Sale Prices of Common Shares on each of
the thirty consecutive Trading Days in the Applicable Conversion Reference
Period. The "Conversion Rate" shall be, at any time of determination, $1,000
divided by the Conversion Price in effect at such time of determination,
rounded to four decimal places. The Conversion Rate shall be initially equal
to 44.2112 Common Shares. The "Conversion Price" shall be initially equal to
$22.6187 per Common Share. The Conversion Price shall be adjusted in certain
instances as provided in paragraphs (a), (b), (c), (d), (e), (f), (g) and (i)
of Section 10.04.

         The "Daily Share Amount" for each day in the Applicable Conversion
Reference Period is equal to the greater of:

         o Zero; or

         o A number of Common Shares determined by the following formula:

                (Sale Price on that Trading Day x Conversion Rate) - $1,000
                            30 x Sale Price on that Trading Day

The daily share amount for each day shall be rounded to four decimal places.


         The "Applicable Conversion Reference Period" means:

         o     For a Note that is converted after a redemption notice has been
               mailed by the Company pursuant to Section 3.03 and paragraph 7
               of the Notes, the thirty consecutive trading days beginning on
               the Trading Day following the Redemption Date (in the case of a
               partial redemption, this clause applies only to those Notes
               which would be actually redeemed); or


                                      49



         o     In all other cases, the thirty consecutive Trading Days
               beginning on the Trading Day following the Conversion Date.

         The cash in respect of the Principal Return and cash in lieu of
fractional shares shall be paid, and a certificate or certificates for the
number of full Net Shares issuable upon conversion, if any, shall be delivered
as promptly as practicable after the Applicable Conversion Reference Period,
but in no event later than five Business Days thereafter.

         In case a Note or portion thereof is called for redemption, such
conversion right in respect of the Note or the portion so called, shall expire
at the close of business on the Business Day preceding the Redemption Date,
unless the Company defaults in making the payment due upon redemption. In the
case of a Change in Control for which the Holder exercises its repurchase
right with respect to a Note or portion thereof, such conversion right in
respect of the Note or portion thereof shall expire at the close of business
on the Business Day immediately preceding the Change in Control Repurchase
Date.

         Upon a determination that Holders are or will be entitled to convert
their Notes into the Principal Return and Net Shares, if any, in accordance
with the provisions of this Article 10, the Company shall issue a press
release and publish such information on its website.

         SECTION 10.02      Exercise of Conversion Right
                            ----------------------------

         To exercise the conversion right, the Holder of any Note to be
converted shall comply with the procedures required by paragraph 8 of the
Notes.

         Notes surrendered for conversion (other than Notes called for
redemption) during the period from the close of business on any Regular Record
Date to the opening of business on the next succeeding Interest Payment Date
shall be accompanied by payment in New York Clearing House funds or other
funds acceptable to the Company of an amount equal to the interest to be
received on such Interest Payment Date on the principal amount of Notes being
surrendered for conversion. No payment will be required from a Holder if the
Company elects to redeem the Notes.

         Notes shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Notes for conversion in
accordance with the foregoing provisions (the "Conversion Date"), and at such
time the rights of the Holders of such Notes as Holders shall cease, and the
Person or Persons entitled to receive the Principal Return and Net Shares
issuable upon conversion shall be treated for all purposes as the record
holder or holders of such Net Shares at such time.

         The delivery by the Company to the Holder of the Principal Return and
Net Shares, if any, into which such Holder's Notes are convertible, together
with any cash payment for the Holder's fractional Common Shares, will be
deemed to satisfy the Company's obligation to pay the principal amount at the
Stated Maturity of such Holder's Notes. Holders will not receive any cash
payment representing accrued and unpaid interest, if any, upon conversion of a
Note. Accrued and unpaid interest, if any, will be deemed canceled,
extinguished or forfeited rather than paid in full.


                                      50



         In the case of any Note which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Note or
Notes of authorized denominations in aggregate principal amount equal to the
unconverted portion of the principal amount of the Notes submitted for
conversion.

         If the Holder converts more than one Note at the same time, the
Principal Return and Net Shares, if any, deliverable upon the conversion shall
be based on the total principal amount of the Notes converted.

         A Note surrendered for conversion based on (a) the Common Share
price, as more fully described in paragraph 8 in the Note, may be surrendered
for conversion until the close of business on the final Business Day of any
calendar quarter immediately following a Qualifying Quarter (but in no event
later than the close of business on the Business Day immediately preceding the
Stated Maturity of the principal of the Note), (b) a credit downgrade or the
absence, suspension or withdrawal of a credit rating, may be surrendered for
conversion until the close of business on any Business Day during the period
of the credit downgrade or the absence, suspension or withdrawal of the credit
rating, as more fully described in paragraph 8 in the Note, (c) the Note being
called for redemption, may be surrendered for conversion at any time prior to
the close of business on the Business Day immediately preceding the Redemption
Date, even if it is not otherwise convertible at such time, and (d) upon the
occurrence of certain corporate transactions more fully described in paragraph
8 in the Note, 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.

         SECTION 10.03      Fractions of Shares
                            -------------------

         No fractional Common Shares shall be issued upon conversion of any
Note or Notes. If more than one Note shall be surrendered for conversion at
one time by the same Holder, the Principal Return and number of Net Shares, if
any, which shall be delivered upon conversion thereof shall be computed on the
basis of the aggregate principal amount of the Notes (or specified portions
thereof) so surrendered. Instead of any fractional Common Shares which would
otherwise be issued upon conversion of any Note or Notes (or specified
portions thereof), the Company shall pay a cash adjustment in respect of such
fraction (rounded to four decimal places) in an amount equal to the same
fraction of value of such fractional share based on the average of the Sale
Prices of the Company's Common Shares on each of the thirty consecutive
Trading Days in the Applicable Conversion Reference period.

         SECTION 10.04      Adjustment of Conversion Price
                            ------------------------------

         The Conversion Price shall be subject to adjustments, calculated by
the Company, from time to time as follows:

         (a) In case the Company shall hereafter pay a dividend or make a
distribution in Common Shares to all holders of the outstanding Common
Shares, the Conversion Price in effect at the opening of business on the
date following the date fixed for the determination of


                                      51



shareholders entitled to receive such dividend or other distribution shall be
reduced by multiplying such Conversion Price by a fraction:

               (1) the numerator of which shall be the number of Common Shares
         outstanding at the close of business on the Record Date (as defined
         in Section 10.04(h)) fixed for such determination, and

               (2) the denominator of which shall be the sum of such number of
         Common Shares and the total number of Common Shares constituting such
         dividend or other distribution.

     Such reduction shall become effective immediately after the opening of
     business on the day following the Record Date. If any dividend or
     distribution of the type described in this Section 10.04(a) is declared
     but not so paid or made, the Conversion Price shall again be adjusted to
     the Conversion Price which would then be in effect if such dividend or
     distribution had not been declared.

         (b) In case the outstanding Common Shares shall be subdivided into a
     greater number of Common Shares, the Conversion Price in effect at the
     opening of business on the day following the day upon which such
     subdivision becomes effective shall be proportionately reduced, and
     conversely, in case outstanding Common Shares shall be combined into a
     smaller number of Common Shares, the Conversion Price in effect at the
     opening of business on the day following the day upon which such
     combination becomes effective shall be proportionately increased, such
     reduction or increase, as the case may be, to become effective
     immediately after the opening of business on the day following the day
     upon which such subdivision or combination becomes effective.

         (c) In case the Company shall issue rights or warrants (other than
     any rights or warrants referred to in Section 10.04(d)) to all holders of
     its outstanding Common Shares entitling them to subscribe for or purchase
     Common Shares (or securities convertible into Common Shares) at a price
     per Common Share (or having a conversion price per share) less than the
     Current Market Price (as defined in Section 10.04(h)) on the Record Date
     fixed for the determination of shareholders entitled to receive such
     rights or warrants, the Conversion Price shall be adjusted so that the
     same shall equal the price determined by multiplying the Conversion Price
     in effect at the opening of business on the date after such Record Date
     by a fraction:

               (1) the numerator of which shall be the number of Common Shares
         outstanding at the close of business on the Record Date plus the
         number of Common Shares which the aggregate offering price of the
         total number of Common Shares so offered for subscription or purchase
         (or the aggregate conversion price of the convertible securities so
         offered) would purchase at such Current Market Price, and

               (2) the denominator of which shall be the number of Common
         Shares outstanding on the close of business on the Record Date plus
         the total number of


                                      52



         additional Common Shares so offered for subscription or purchase (or
         into which the convertible securities so offered are convertible).

     Such adjustment shall become effective immediately after the opening of
     business on the day following the Record Date fixed for determination of
     shareholders entitled to receive such rights or warrants. To the extent
     that Common Shares (or securities convertible into Common Shares) are not
     delivered pursuant to such rights or warrants, upon the expiration or
     termination of such rights or warrants the Conversion Price shall be
     readjusted to the Conversion Price which would then be in effect had the
     adjustments made upon the issuance of such rights or warrants been made
     on the basis of the delivery of only the number of Common Shares (or
     securities convertible into Common Shares) actually delivered. In the
     event that such rights or warrants are not so issued, the Conversion
     Price shall again be adjusted to be the Conversion Price which would then
     be in effect if such date fixed for the determination of shareholders
     entitled to receive such rights or warrants had not been fixed. In
     determining whether any rights or warrants entitle the holders to
     subscribe for or purchase Common Shares at less than such Current Market
     Price, and in determining the aggregate offering price of such Common
     Shares, there shall be taken into account any consideration received for
     such rights or warrants, the value of such consideration if other than
     cash, to be determined by the Board of Directors.

         (d) In case the Company shall, by dividend or otherwise, distribute
     to all holders of its Common Shares shares of any class of Capital Stock
     of the Company (other than any dividends or distributions to which
     Section 10.04(a) applies) or evidences of its indebtedness or other
     assets, including securities (other than any dividends or distributions
     to which Section 10.04(g) applies), but excluding (1) any rights or
     warrants referred to in Section 10.04(c), (2) any distributions in
     connection with a reclassification, change, consolidation, merger,
     combination, sale or conveyance to which Section 10.11 applies and (3)
     dividends and distributions paid exclusively in cash (the securities
     described in foregoing clauses (1), (2) and (3) hereinafter in this
     Section 10.04(d) called the "excluded securities"), then, in each such
     case, subject to the second succeeding paragraph of this Section
     10.04(d), the Conversion Price shall be adjusted so that the same shall
     be equal to the price determined by multiplying the Conversion Price in
     effect immediately prior to the close of business on the Record Date (as
     defined in Section 10.04(h)) with respect to such distribution by a
     fraction:

               (1) the numerator of which shall be the Current Market Price
         (determined as provided in Section 10.04(h)) on such date less the
         fair market value (as determined by the Board of Directors, whose
         determination shall be conclusive and set forth in a Board
         Resolution) on such date of the portion of the securities so
         distributed (other than excluded securities) applicable to one Common
         Share (determined on the basis of the number of Common Shares
         outstanding on the Record Date), and

               (2) the denominator of which shall be such Current Market Price.


                                      53



         Such reduction shall become effective immediately prior to the
         opening of business on the day following the Record Date. However, in
         the event that the then fair market value (as so determined) of the
         portion of the securities so distributed (other than excluded
         securities) applicable to one Common Share is equal to or greater
         than the Current Market Price on the Record Date, in lieu of the
         foregoing adjustment, adequate provision shall be made so that each
         Holder shall have the right to receive upon conversion of a Note (or
         any portion thereof) the amount of securities so distributed (other
         than excluded securities) such Holder would have received had such
         Holder converted such Note (or portion thereof) immediately prior to
         such Record Date. In the event that such dividend or distribution is
         not so paid or made, the Conversion Price shall again be adjusted to
         be the Conversion Price which would then be in effect if such
         dividend or distribution had not been declared.

                  If the Board of Directors determines the fair market value
         of any distribution for purposes of this Section 10.04(d) by
         reference to the actual or when issued trading market for any
         securities comprising all or part of such distribution (other than
         excluded securities), it must, in doing so, consider the prices in
         such market over the same period (the "Reference Period") used in
         computing the Current Market Price pursuant to Section 10.04(h) to
         the extent possible, unless the Board of Directors in a Board
         Resolution determines in good faith that determining the fair market
         value during the Reference Period would not be in the best interest
         of the Holder.

                  Rights or warrants distributed by the Company to all holders
         of Common Shares entitling the holders thereof to subscribe for or
         purchase shares of the Company's Capital Stock (either initially or
         under certain circumstances), which rights or warrants, until the
         occurrence of a specified event or events ("Trigger Event"):

               (i) are deemed to be transferred with such Common Shares;

               (ii) are not exercisable; and

               (iii) are also issued in respect of future issuances of Common
               Shares,

         shall be deemed not to have been distributed for purposes of this
         Section 10.04(d) (and no adjustment to the Conversion Price under
         this Section 10.04(d) will be required) until the occurrence of the
         earliest Trigger Event. If such right or warrant is subject to
         subsequent events, upon the occurrence of which such right or warrant
         shall become exercisable to purchase different securities, evidences
         of indebtedness or other assets or entitle the holder to purchase a
         different number or amount of the foregoing or to purchase any of the
         foregoing at a different purchase price, then the occurrence of each
         such event shall be deemed to be the date of issuance and record date
         with respect to a new right or warrant (and a termination or
         expiration of the existing right or warrant without exercise by the
         holder thereof). In addition, in the event of any distribution (or
         deemed distribution) of rights or warrants, or any Trigger Event or
         other event (of the type described in the preceding sentence) with
         respect thereto, that resulted in an adjustment to the Conversion
         Price under this Section 10.04(d):


                                      54



               (1) in the case of any such rights or warrants which shall all
         have been redeemed or repurchased without exercise by any holders
         thereof, the Conversion Price shall be readjusted upon such final
         redemption or repurchase to give effect to such distribution or
         Trigger Event, as the case may be, as though it were a cash
         distribution, equal to the per share redemption or repurchase price
         received by a holder of Common Shares with respect to such rights or
         warrant (assuming such holder had retained such rights or warrants),
         made to all holders of Common Shares as of the date of such
         redemption or repurchase, and

               (2) in the case of such rights or warrants all of which shall
         have expired or been terminated without exercise, the Conversion
         Price shall be readjusted as if such rights and warrants had never
         been issued.

         For purposes of this Section 10.04(d) and Sections 10.04(a), 10.04(b)
     and 10.04(c), any dividend or distribution to which this Section 10.04(d)
     is applicable that also includes Common Shares, a subdivision or
     combination of Common Shares to which Section 10.04(b) applies, or rights
     or warrants to subscribe for or purchase Common Shares to which Section
     10.04(c) applies (or any combination thereof), shall be deemed instead to
     be:

               (1) a dividend or distribution of the evidences of
         indebtedness, assets, shares of Capital Stock, rights or warrants
         other than Common Shares, such subdivision or combination or such
         rights or warrants to which Sections 10.04(a), 10.04(b) and 10.04(c)
         apply, respectively (and any Conversion Price reduction required by
         this Section 10.04(d) with respect to such dividend or distribution
         shall then be made), immediately followed by

               (2) a dividend or distribution of such Common Shares, such
         subdivision or combination or such rights or warrants (and any
         further Conversion Price reduction required by Sections 10.04(a),
         10.04(b) and 10.04(c) with respect to such dividend or distribution
         shall then be made), except:

                  (A) the Record Date of such dividend or distribution shall
               be substituted as (x) "the date fixed for the determination of
               shareholders entitled to receive such dividend or other
               distribution", "Record Date fixed for such determinations" and
               "Record Date" within the meaning of Section 10.04(a), (y) "the
               day upon which such subdivision becomes effective" and "the day
               upon which such combination becomes effective" within the
               meaning of Section 10.04(b), and (z) as "the date fixed for the
               determination of shareholders entitled to receive such rights
               or warrants", "the Record Date fixed for the determination of
               the shareholders entitled to receive such rights or warrants"
               and such "Record Date" within the meaning of Section 10.04(c),
               and

                  (B) any Common Shares included in such dividend or
               distribution shall not be deemed "outstanding at the close of
               business on the date fixed for such determination" within the
               meaning of Section 10.04(a)


                                      55



                  and any reduction or increase in the number of Common Shares
                  resulting from such subdivision or combination shall be
                  disregarded in connection with such dividend or
                  distribution.

         (e) In case the Company shall, by dividend or otherwise, distribute
     to all holders of its Common Shares cash, in an aggregate amount that,
     combined together with: (1) the aggregate amount of any other such
     distributions to all holders of Common Shares made exclusively in cash
     within the 12 months preceding the date of payment of such distribution,
     and in respect of which no adjustment pursuant to this Section 10.04(e)
     has been made, and (2) the aggregate of any cash plus the fair market
     value (as determined by the Board of Directors, whose determination shall
     be conclusive and set forth in a Board Resolution) of consideration
     payable in respect of any tender offer by the Company or any of its
     subsidiaries for all or any portion of the Common Shares concluded within
     the 12 months preceding the date of such distribution, and in respect of
     which no adjustment pursuant to Section 10.04(f) has been made, exceeds
     10% of the product of the Current Market Price (determined as provided in
     Section 10.04(h)) on the Record Date with respect to such distribution
     times the number of Common Shares outstanding on such date, then and in
     each such case, immediately after the close of business on such date, the
     Conversion Price shall be reduced so that the same shall equal the price
     determined by multiplying the Conversion Price in effect immediately
     prior to the close of business on such Record Date by a fraction:

               (i) the numerator of which shall be equal to the Current Market
         Price on the Record Date less an amount equal to the quotient of (x)
         the excess of such combined amount over such 10% and (y) the number
         of Common Shares outstanding on the Record Date, and

               (ii) the denominator of which shall be equal to the Current
         Market Price on such date.

     However, in the event that the then fair market value (as so determined)
     of the portion of the securities so distributed (other than excluded
     securities) applicable to one Common Share is equal to or greater than
     the Current Market Price on the Record Date, in lieu of the foregoing
     adjustment, adequate provision shall be made so that each Holder shall
     have the right to receive upon conversion of a Note (or any portion
     thereof) the amount of cash such Holder would have received had such
     Holder converted such Note (or portion thereof) immediately prior to such
     Record Date. In the event that such dividend or distribution is not so
     paid or made, the Conversion Price shall again be adjusted to be the
     Conversion Price which would then be in effect if such dividend or
     distribution had not been declared.

         (f) In case a tender offer made by the Company or any of its
     Subsidiaries for all or any portion of the Common Shares shall expire and
     such tender offer (as amended upon the expiration thereof) shall require
     the payment to shareholders (based on the acceptance (up to any maximum
     specified in the terms of the tender offer) of Purchased Shares (as
     defined below)) of an aggregate consideration having a fair market value
     (as


                                      56



     determined by the Board of Directors, whose determination shall be
     conclusive and set forth in a Board Resolution) that combined together
     with:

               (1) the aggregate of the cash plus the fair market value (as
         determined by the Board of Directors, whose determination shall be
         conclusive and set forth in a Board Resolution), as of the expiration
         of such tender offer, of consideration payable in respect of any
         other tender offers, by the Company or any of its Subsidiaries for
         all or any portion of the Common Shares expiring within the 12 months
         preceding the expiration of such tender offer and in respect of which
         no adjustment pursuant to this Section 10.04(f) has been made, and

               (2) the aggregate amount of any distributions to all holders of
         the Company's Common Shares made exclusively in cash within 12 months
         preceding the expiration of such tender offer and in respect of which
         no adjustment pursuant to Section 10.04(e) has been made, exceeds 10%
         of the product of the Current Market Price (determined as provided in
         Section 10.04(h)) as of the last time (the "Expiration Time") tenders
         could have been made pursuant to such tender offer (as it may be
         amended) multiplied by the number of Common Shares outstanding
         (including any Common Shares tendered) as of the Expiration Time,
         then, and in each such case, immediately prior to the opening of
         business on the day after the date of the Expiration Time, the
         Conversion Price shall be adjusted so that the same shall equal the
         price determined by multiplying the Conversion Price in effect
         immediately prior to close of business on the date of the Expiration
         Time by a fraction:

                   (i) the numerator of which shall be the number of Common
               Shares outstanding (including any Common Shares tendered) at
               the Expiration Time multiplied by the Current Market Price of
               the Common Shares on the Trading Day next succeeding the
               Expiration Time, and

                   (ii) the denominator shall be the sum of (x) the fair
               market value (determined as aforesaid) of the aggregate
               consideration payable to shareholders based on the acceptance
               (up to any maximum specified in the terms of the tender offer)
               of all Common Shares validly tendered and not withdrawn as of
               the Expiration Time (the Common Shares deemed so accepted, up
               to any such maximum, being referred to as the "Purchased
               Shares") and (y) the product of the number of Common Shares
               outstanding (less any Purchased Shares) at the Expiration Time
               and the Current Market Price of the Common Shares on the
               Trading Day next succeeding the Expiration Time.

     Such reduction (if any) shall become effective immediately prior to the
     opening of business on the day following the Expiration Time. In the
     event that the Company is obligated to purchase Common Shares pursuant to
     any such tender offer, but the Company is permanently prevented by
     applicable law from effecting any such purchases or all such purchases
     are rescinded, the Conversion Price shall again be adjusted to be the
     Conversion Price which would then be in effect if such tender offer had
     not been made.


                                      57



     If the application of this Section 10.04(f) to any tender offer would
     result in an increase in the Conversion Price, no adjustment shall be
     made for such tender offer under this Section 10.04(f).

         (g) If, after the Issue Date, the Company pays a dividend or makes a
     distribution to all holders of its Common Shares consisting of Capital
     Stock of, or similar equity interests in, a Subsidiary or other business
     unit of the Company, then and in each such case, the Conversion Price
     shall be adjusted so that the same shall equal the price determined by
     multiplying the Conversion Price in effect immediately prior to the date
     on which Common Shares first trade regular way without the right to
     receive such dividend or distribution by an amount equal to one (1) minus
     a fraction:

               (1) the numerator of which shall be the Value Distributed Per
         Share, and

               (2) the denominator of which shall be the sum of (x) the
         average of the Sale Prices of the Common Shares during the ten (10)
         Trading Days commencing on and including the fifth Trading Day after
         the date on which Common Shares trade regular way on the relevant
         exchange or in the relevant market from which the Sale Price was
         obtained without the right to receive such dividend or distribution
         plus (y) the Value Distributed Per Share.


     Such reduction (if any) shall become effective as of the opening of
     business on the day on which Common Shares first trade regular way
     without the right to receive such dividend or distribution. If any
     dividend or distribution of the type described in this Section 10.04(g)
     is declared but not so paid or made, the Conversion Price shall again be
     adjusted to the Conversion Price which would then be in effect if such
     dividend or distribution had not been declared.

         (h) For purposes of this Section 10.04, the following terms shall
     have the meanings indicated:

               (1) "Current Market Price" shall mean the average of the daily
         Sale Prices per Common Share for the ten consecutive Trading Days
         immediately prior to the date in question; provided, however, that
         if:

                   (i) the "ex" date (as hereinafter defined) for any event
               (other than the issuance or distribution requiring such
               computation) that requires an adjustment to the Conversion
               Price pursuant to Section 10.04(a), (b), (c), (d), (e) or (f)
               occurs during such ten consecutive Trading Days, the Sale Price
               for each Trading Day prior to the "ex" date for such other
               event shall be adjusted by multiplying such Sale Price by the
               same fraction by which the Conversion Price is so required to
               be adjusted as a result of such other event;


                                      58



                   (ii) the "ex" date for any event (other than the issuance
               or distribution requiring such computation) that requires an
               adjustment to the Conversion Price pursuant to Section
               10.04(a), (b), (c), (d), (e) or (f) occurs on or after the "ex"
               date for the issuance or distribution requiring such
               computation and prior to the day in question, the Sale Price
               for each Trading Day on and after the "ex" date for such other
               event shall be adjusted by multiplying such Sale Price by the
               reciprocal of the fraction by which the Conversion Price is so
               required to be adjusted as a result of such other event; and

                   (iii) the "ex" date for the issuance or distribution
               requiring such computation is prior to the day in question,
               after taking into account any adjustment required pursuant to
               clause (i) or (ii) of this proviso, the Sale Price for each
               Trading Day on or after such "ex" date shall be adjusted by
               adding thereto the amount of any cash and the fair market value
               (as determined by the Board of Directors in a manner consistent
               with any determination of such value for purposes of Section
               10.04(d) or (f), whose determination shall be conclusive and
               set forth in a Board Resolution) of the evidences of
               indebtedness, shares of Capital Stock or assets being
               distributed applicable to one Common Share as of the close of
               business on the day before such "ex" date.

     For purposes of any computation under Section 10.04(f), the Current
     Market Price of the Common Shares on any date shall be deemed to be the
     average of the daily Sale Prices per Common Share for such day and the
     next two succeeding Trading Days; provided, however, that if the "ex"
     date for any event (other than the tender offer requiring such
     computation) that requires an adjustment to the Conversion Price pursuant
     to Section 10.04(a), (b), (c), (d), (e) or (f) occurs on or after the
     Expiration Time for the tender or exchange offer requiring such
     computation and prior to the day in question, the Sale Price for each
     Trading Day on and after the "ex" date for such other event shall be
     adjusted by multiplying such Sale Price by the reciprocal of the fraction
     by which the Conversion Price is so required to be adjusted as a result
     of such other event. For purposes of this paragraph, the term "ex" date,
     when used:

         (A) with respect to any issuance or distribution, means the first
     date on which the Common Shares trade regular way on the relevant
     exchange or in the relevant market from which the Sale Price was obtained
     without the right to receive such issuance or distribution;

         (B) with respect to any subdivision or combination of Common Shares,
     means the first date on which the Common Shares trade regular way on such
     exchange or in such market after the time at which such subdivision or
     combination becomes effective, and

         (C) with respect to any tender or exchange offer, means the first
     date on which the Common Shares trade regular way on such exchange or in
     such market after the Expiration Time of such offer.


                                      59



     Notwithstanding the foregoing, whenever successive adjustments to the
     Conversion Price are called for pursuant to this Section 10.04, such
     adjustments shall be made to the Current Market Price as may be necessary
     or appropriate to effectuate the intent of this Section 10.04 and to
     avoid unjust or inequitable results as determined in good faith by the
     Board of Directors.

               (2) "fair market value" shall mean the amount which a willing
         buyer would pay a willing seller in an arm's length transaction.

               (3) "Record Date" shall mean, with respect to any dividend,
         distribution or other transaction or event in which the holders of
         Common Shares have the right to receive any cash, securities or other
         property or in which the Common Shares (or other applicable security)
         is exchanged for or converted into any combination of cash,
         securities or other property, the date fixed for determination of
         shareholders entitled to receive such cash, securities or other
         property (whether such date is fixed by the Board of Directors or by
         statute, contract or otherwise).

         (i) The Company may make such reductions in the Conversion Price, in
     addition to those required by Section 10.04(a), (b), (c), (d), (e), (f)
     or (g), as the Board of Directors considers to be advisable to avoid or
     diminish any income tax to holders of Common Shares or rights to purchase
     Common Shares resulting from any dividend or distribution of stock (or
     rights to acquire stock) or from any event treated as such for income tax
     purposes.

         To the extent permitted by applicable law, the Company from time to
     time may reduce the Conversion Price by any amount for any period of time
     if the period is at least 20 days and the reduction is irrevocable during
     the period and the Board of Directors determines in good faith that such
     reduction would be in the best interests of the Company, which
     determination shall be conclusive and set forth in a Board Resolution.
     Whenever the Conversion Price is reduced pursuant to the preceding
     sentence, the Company shall mail to the Trustee and each Holder at the
     address of such Holder as it appears in the Register a notice of the
     reduction at least 15 days prior to the date the reduced Conversion Price
     takes effect, and such notice shall state the reduced Conversion Price
     and the period during which it will be in effect.

         (j) No adjustment in the Conversion Price shall be required unless
     such adjustment would require an increase or decrease of at least 1% in
     such price; provided, however, that any adjustments which by reason of
     this Section 10.04(j) are not required to be made shall be carried
     forward and taken into account in any subsequent adjustment. All
     calculations under this Article 10 shall be made by the Company and shall
     be made to the nearest cent or to the nearest one hundredth of a share,
     as the case may be. No adjustment need be made for a change in the par
     value or no par value of the Common Shares.

         (k) In any case in which this Section 10.04 provides that an
     adjustment shall become effective immediately after a Record Date for an
     event, the Company may defer


                                      60



     until the occurrence of such event (i) issuing to the Holder of any Note
     converted after such Record Date and before the occurrence of such event
     the additional Common Shares issuable upon such conversion by reason of
     the adjustment required by such event over and above the Common Shares
     issuable upon such conversion before giving effect to such adjustment and
     (ii) paying to such holder any amount in cash in lieu of any fraction
     pursuant to Section 10.03.

         (l) For purposes of this Section 10.04, the number of Common Shares
     at any time outstanding shall not include Common Shares held in the
     treasury of the Company but shall include Common Shares issuable in
     respect of scrip certificates issued in lieu of fractions of Common
     Shares. The Company will not pay any dividend or make any distribution on
     Common Shares held in the treasury of the Company.

         (m) If the distribution date for the rights provided in the Company's
     rights agreement, if any, occurs prior to the date a Note is converted,
     the Holder of the Note who converts such Note after the distribution date
     is not entitled to receive the rights that would otherwise be attached
     (but for the date of conversion) to the Common Shares received upon such
     conversion; provided, however, that an adjustment shall be made to the
     Conversion Price pursuant to Section 10.04(b) as if the rights were being
     distributed to the common shareholders of the Company immediately prior
     to such conversion. If such an adjustment is made and the rights are
     later redeemed, invalidated or terminated, then a corresponding reversing
     adjustment shall be made to the Conversion Price, on an equitable basis,
     to take account of such event.

         SECTION 10.05      Notice of Adjustments of Conversion Price
                            -----------------------------------------

         Whenever the Conversion Price is adjusted as herein provided (other
than in the case of an adjustment pursuant to the second paragraph of Section
10.04(i) for which the notice required by such paragraph has been provided),
the Company shall promptly file with the Trustee and any Conversion Agent
other than the Trustee an Officers' Certificate setting forth the adjusted
Conversion Price and showing in reasonable detail the facts upon which such
adjustment is based. Promptly after delivery of such Officers' Certificate,
the Company shall prepare a notice stating that the Conversion Price has been
adjusted and setting forth the adjusted Conversion Price and the date on which
each adjustment becomes effective, and shall mail such notice to each Holder
at the address of such Holder as it appears in the Register within 20 days of
the effective date of such adjustment. Failure to deliver such notice shall
not effect the legality or validity of any such adjustment.

         SECTION 10.06      Notice Prior to Certain Actions
                            -------------------------------

         In case at any time after the date hereof:

         (1) the Company shall declare a dividend (or any other distribution)
     on its Common Shares payable otherwise than in cash out of its capital
     surplus or its consolidated retained earnings;

         (2) the Company shall authorize the granting to the holders of its
     Common Shares of rights or warrants to subscribe for or purchase any
     shares of Capital Stock of


                                      61



     any class (or of securities convertible into shares of capital stock of
     any class) or of any other rights;

         (3) there shall occur any reclassification of the Common Shares of
     the Company (other than a subdivision or combination of its outstanding
     Common Shares, a change in par value, a change from par value to no par
     value or a change from no par value to par value), or any merger or
     combination to which the Company is a party and for which approval of any
     shareholders of the Company is required, or the sale, transfer or
     conveyance of all or substantially all of the assets of the Company; or

         (4) there shall occur the voluntary or involuntary dissolution,
     liquidation or winding up of the Company;

the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Notes pursuant to Section 4.05, and shall cause
to be provided to the Trustee and all Holders in accordance with Section
11.02, at least 20 days (or 10 days in any case specified in clause (1) or (2)
above) prior to the applicable record or effective date hereinafter specified,
a notice stating:

               (A) the date on which a record is to be taken for the purpose
         of such dividend, distribution, rights or warrants, or, if a record
         is not to be taken, the date as of which the holders of Common Shares
         of record to be entitled to such dividend, distribution, rights or
         warrants are to be determined, or

               (B) the date on which such reclassification, merger,
         combination, sale, transfer, conveyance, dissolution, liquidation or
         winding up is expected to become effective, and the date as of which
         it is expected that holders of Common Shares of record shall be
         entitled to exchange their Common Shares for securities, cash or
         other property deliverable upon such reclassification, merger, sale,
         transfer, dissolution, liquidation or winding up.

         Neither the failure to give such notice nor any defect therein shall
     affect the legality or validity of the proceedings or actions described
     in clauses (1) through (4) of this Section 10.06.

         SECTION 10.07      Company to Reserve Common Shares
                            --------------------------------

         The Company shall at all times use its best efforts to reserve and
keep available, free from preemptive rights, out of its authorized but
unissued Common Shares, for the purpose of effecting the conversion of Notes,
the full number of shares of fully paid and nonassessable Common Shares then
issuable upon the conversion of all Notes outstanding.

         The Company will endeavor promptly to comply with all federal and
state securities laws regulating the offer and delivery of Common Shares
upon conversion of Notes, if any, and will list or cause to have quoted
such Common Shares on each national securities


                                      62



exchange or in the over-the-counter market or such other market on which the
Common Shares are then listed or quoted.

         SECTION 10.08      Taxes on Conversions
                            --------------------

         Except as provided in the next sentence, the Company will pay any and
all taxes (other than taxes on income) and duties that may be payable in
respect of the issue or delivery of Principal Return and Net Shares, if any,
on conversion of Notes pursuant hereto. A Holder delivering a Note for
conversion shall be liable for and will be required to pay any tax or duty
which may be payable in respect of any transfer involved in the issue and
delivery of Principal Return and Net Shares, if any, in a name other than that
of the Holder of the Note or Notes to be converted, and no such issue or
delivery shall be made unless the Person requesting such issue has paid to the
Company the amount of any such tax or duty, or has established to the
satisfaction of the Company that such tax or duty has been paid.

         SECTION 10.09      Covenant as to Common Shares
                            ----------------------------

         The Company covenants that all Common Shares which may be issued upon
conversion of Notes shall be newly issued shares or treasury shares and will
upon issue be duly and validly issued and fully paid and nonassessable, free
from preemptive rights and free of any Lien or adverse claim, except as
provided in Section 10.08, the Company will pay all taxes, liens and charges
with respect to the issue thereof.

         SECTION 10.10      Cancellation of Converted Notes
                            -------------------------------

         All Notes delivered for conversion shall be delivered to the Trustee
to be canceled by or at the direction of the Trustee, which shall dispose of
the same as provided in Section 2.10.

         SECTION 10.11      Effect of Reclassification, Consolidation, Merger or
                            ----------------------------------------------------
Sale
- ----

         If any of following events occur, namely:

         (1) any reclassification or change of the outstanding Common Shares
     (other than a change in par value, or from par value to no par value, or
     from no par value to par value, or as a result of a subdivision or
     combination),

         (2) any merger, consolidation or combination of the Company with
     another corporation as a result of which holders of Common Shares shall
     be entitled to receive stock, securities or other property or assets
     (including cash or any combination thereof) with respect to or in
     exchange for such Common Shares, or

         (3) any sale or conveyance of the properties and assets of the
     Company as, or substantially as, an entirety to any other corporation as
     a result of which holders of Common Shares shall be entitled to receive
     stock, securities or other property or assets (including cash or any
     combination thereof) with respect to or in exchange for such Common
     Shares,


                                      63



the Company or the successor or purchasing corporation, as the case may be,
shall execute with the Trustee a supplemental indenture (which shall comply
with the TIA as in force at the date of execution of such supplemental
indenture if such supplemental indenture is then required to so comply)
providing that such Note shall be convertible into the kind and amount of
shares of stock and other securities or property or assets (including cash or
any combination thereof) which such Holder would have been entitled to receive
upon such reclassification, change, merger, combination, sale or conveyance
had such Notes been converted into Principal Return and Net Shares, if any,
immediately prior to such reclassification, change, merger, combination, sale
or conveyance assuming such holder of Common Shares did not exercise its
rights of election, if any, as to the kind or amount of securities, cash or
other property receivable upon such reclassification, change, merger,
combination, sale or conveyance (provided that, if the kind or amount of
securities, cash or other property receivable upon such reclassification,
change, merger, combination, sale or conveyance is not the same for each
Common Share in respect of which such rights of election shall not have been
exercised ("Non-Electing Share"), then for the purposes of this Section 10.11
the kind and amount of securities, cash or other property receivable upon such
reclassification, change, merger, combination, sale or conveyance for each
Non-Electing Share shall be deemed to be the kind and amount so receivable per
share by a plurality of the Non-Electing Shares). Such supplemental indenture
shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 10. If, in the
case of any such reclassification, change, merger, combination, sale or
conveyance, the stock or other securities and assets receivable thereupon by a
holder of Common Shares includes shares of stock or other securities and
assets of a corporation other than the successor or purchasing corporation, as
the case may be, in such reclassification, change, merger, combination, sale
or conveyance, then such supplemental indenture shall also be executed by such
other corporation and shall contain such additional provisions to protect the
interests of the Holders of the Notes as the Board of Directors shall
reasonably consider necessary by reason of the foregoing, including to the
extent practicable the provisions providing for the repurchase rights set
forth in Section 3.09.

         The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each Holder, at the address of such Holder as it
appears on the Register, within 20 days after execution thereof. Failure to
deliver such notice shall not affect the legality or validity of such
supplemental indenture.

         The above provisions of this Section 10.11 shall similarly apply to
successive reclassifications, mergers, combinations, sales and conveyances.

         The Company shall not become a party to any of the transactions
described in clauses (1), (2) and (3) of this Section 10.11, unless the terms
of the transaction are consistent with the provisions of this Section 10.11.

         If this Section 10.11 applies to any event or occurrence, Section
10.04 shall not apply.


                                      64



         SECTION 10.12      Responsibility of Trustee for Conversion Provisions
                            ---------------------------------------------------

         The Trustee, subject to the provisions of Section 7.01, and any
Conversion Agent shall not at any time be under any duty or responsibility to
any Holder of Notes to determine whether any facts exist which may require any
adjustment of the Conversion Price, or with respect to the nature or intent of
any such adjustments when made, or with respect to the method employed, or
herein or in any supplemental indenture provided to be employed, in making the
same. Neither the Trustee, subject to the provisions of Section 7.01, nor any
Conversion Agent shall be accountable with respect to the validity or value
(of the kind or amount) of any Common Shares, or of any other securities or
property, which may at any time be issued or delivered upon the conversion of
any Note; and it or they do not make any representation with respect thereto.
Neither the Trustee, subject to the provisions of Section 7.01, nor any
Conversion Agent shall be responsible for any failure of the Company to make
any cash payment or to issue, transfer or deliver any shares of stock or share
certificates or other securities or property upon the surrender of any Note
for the purpose of conversion; and the Trustee, subject to the provisions of
Section 7.01, and any Conversion Agent shall not be responsible or liable for

business on March 4 and September 4 (whether or not a Business Day) (each a
"Regular Record Date"), as the case may be, immediately preceding such
Interest Payment Date. Cash interest on the Notes will accrue from the most
recent date to which interest has been paid or duly provided or, if no
interest has been paid, from the Issue Date. Cash interest will be computed on
the basis of a 360-day year of twelve 30-day months. The Company shall pay
cash interest on overdue principal, or if Common Shares (or cash in lieu of
fractional Common Shares) in respect of a conversion of this Note in
accordance with the terms of Article 10 of the Indenture are not delivered

Paying Agent to collect such payments in respect of the Notes. The Company
will pay cash amounts in money of the United States that at the time of
payment is legal tender for payment of public and private debts. However, the
Company may make such cash payments by check payable in such money. A holder
of Notes with an aggregate principal amount in excess of $5,000,000 will be
paid by wire transfer in immediately available funds at the election of such
holder. Any payment required to be made on any day that is not a Business Day
will be made on the next succeeding Business Day.

maintain at least one Paying Agent in the State of New York, City of New York,
Borough of Manhattan, which shall initially be an office or agency of the
Trustee. The Company or any of its Subsidiaries or any of their Affiliates may

                                    A-1-3



4. Indenture.

         The Company issued the Notes under an Indenture dated as of March 25,
2005 (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 Noteholders are referred to the Indenture and the TIA for
a statement of those terms.

         The Notes are general unsecured obligations of the Company limited to
$65,557,000 aggregate principal amount (subject to Section 2.07 of the
Indenture). The Indenture does not limit other indebtedness of the Company,
secured or unsecured.

5. Redemption at the Option of the Company.

         At any time on or after March 25, 2005, the Company may redeem as a
whole, or from time to time in part, the Notes on at least 30 but not more
than 60 days' notice, at the following prices (expressed in percentages of the
principal amount), together with accrued and unpaid interest to, but
excluding, the date fixed for redemption.

                                                                   Redemption
         During the Twelve Months Commencing                         Price

         March 19, 2006............................................   101%
         March 19, 2007 and thereafter.............................   100%


         If the Company does not redeem all the Notes, the Trustee will select
the Notes to be redeemed in principal amounts of $1,000 or whole multiples of
$1,000 by lot or on a pro rata basis or by any other method the Trustee
considers fair and appropriate (so long as such method is not prohibited by
the rules of any stock exchange on which the Notes are then listed). If any
Notes are to be redeemed in part only, a new Note or Notes in principal amount
equal to the unredeemed principal portion thereof will be issued. If a portion
of a Holder's Notes is selected for partial redemption and the Holder converts
a portion of its Notes, the converted portion will be deemed to be taken from
the portion selected for redemption.

         No sinking fund is provided for the Notes.

                                    A-1-4



6. Repurchase by the Company at the Option of the Holder.


         Subject to the terms and conditions of the Indenture, the Company
shall become obligated to repurchase, at the option of the Holder, the Notes
held by such Holder on March 19, 2007, March 19, 2012 and March 19, 2017 (each
a "Repurchase Date") at a Repurchase Price of 100% of the principal amount of
the Notes to be repurchased, together with interest accrued and unpaid to, but
excluding, the Repurchase Date, upon delivery of a Repurchase Notice
containing the information set forth in the Indenture, at any time from the
opening of business on the date that is 20 Business Days prior to such
Repurchase Date until the close of business on the Business Day immediately
preceding such Repurchase Date and upon delivery of the Notes to the Paying
Agent by the Holder as set forth in the Indenture.

         If a Change in Control occurs, the Holder, at the Holder's option,
shall have the right, in accordance with the provisions of the Indenture, to
require the Company to repurchase the Notes, not previously called for
redemption (or any portion of the principal amount hereof that is at least
$1,000 or an integral multiple thereof, provided that the portion of the
principal amount of this Note to be outstanding after such repurchase is at
least equal to $1,000) at the Change in Control Repurchase Price of 100% of
the principal amount of the Notes to be repurchased, together with interest
accrued and unpaid to, but excluding, the Change in Control Repurchase Date.

         No fractional Common Shares will be issued upon repurchase of any
Notes. Instead of any fractional Common Share which would otherwise be issued
upon conversion of such Notes, the Company shall pay a cash adjustment as
provided in the Indenture.

         A Change in Control Repurchase Notice will be given by the Company to
the Holders as provided in the Indenture. To exercise a repurchase right, a
Holder must deliver to the Trustee a written notice as provided in the
Indenture.

         Holders have the right to withdraw any Change in Control Repurchase
Notice 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 Repurchase Price or Change in Control
Repurchase Price, as the case may be, of all Notes or portions thereof to be
purchased as of the Repurchase Date or the Change in Control Repurchase Date,
as the case may be, is deposited with the Paying Agent on the Repurchase Date
or the Change in Control Repurchase Date, as the case may be, then, on and
after the Repurchase Date or Change in Control Repurchase Date, as the case
may be, the Holder thereof shall have no other rights as a Holder (other than
the right to receive the Repurchase Price or Change in Control Repurchase
Price, as the case may be, if any, upon surrender of such Note).


7. 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 all Notes (or portions thereof) to be redeemed

                                    A-1-5



on the Redemption Date is deposited with the Paying Agent prior to or on the
Redemption Date, immediately after such Redemption Date interest ceases to
accrue on such Notes or portions thereof. Notes in denominations larger than
$1,000 of principal amount may be redeemed in part but only in integral
multiples of $1,000 of principal amount.

8. Conversion.

         Subject to the provisions of this paragraph 8 and the terms of the
Indenture and notwithstanding the fact that any other condition to conversion
has not been satisfied, a Holder may convert Notes into the Principal Return
and Net Shares, if any, at any time during a calendar quarter that immediately
follows a Qualifying Quarter (but in no event later than the close of business
on the Business Day immediately preceding the Stated Maturity of the principal
of the Notes). A "Qualifying Quarter" means a calendar quarter (beginning with
the quarter ending on March 31, 2005) if, as of the last day of such calendar
quarter, the Sale Price of the Common Shares for at least 20 Trading Days in a
period of 30 consecutive Trading Days ending on the last Trading Day of such
quarter is more than 110% of the Conversion Price on the last day of such
quarter.

         Subject to the provisions of this paragraph 8 and the Indenture and
notwithstanding the fact any other condition to conversion has not been
satisfied, a Holder may convert the Notes into the Principal Return and Net
Shares, if any, during any period in which (i) the credit rating assigned to
the Notes by a Rating Agency is reduced to or below the Applicable Rating,
(ii) the Notes are no longer rated by a Rating Agency or (iii) the credit
ratings assigned to the Notes have been suspended or withdrawn by a Rating
Agency. "Rating Agency" means (1) Moody's Investors Service, Inc. and its
successors ("Moody's") and (2) Standard & Poor's Credit Market Services, a
division of The McGraw-Hill Companies Inc., and its successors ("Standard &
Poor's"). "Applicable Rating" means (1) Ba2, in the case of Moody's (or its
equivalent under any successor ratings categories of Moody's) and (2) B+, in
the case of Standard & Poor's (or its equivalent under any successor ratings
categories of Standard & Poor's).

         Subject to the provisions of this paragraph 8 and the Indenture and
notwithstanding the fact that any other condition to conversion has not been
satisfied, a Holder may convert into the Principal Return and Net Shares, if
any, a Note or portion of a Note which has been called for redemption pursuant
to paragraph 5, even if the Note, or any portion thereof, is not subject to
conversion by the Holder, provided such Notes are surrendered for conversion
prior to the close of business on the Business Day immediately preceding the
Redemption Date.

         Subject to the provisions of this paragraph 8 and the Indenture and
notwithstanding the fact that any other condition 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 Shares would be converted
into cash, securities or other property as set forth in Section 5.01 of the
Indenture, a Holder may convert the Notes at any time from and after the date
which is 15 days prior to the date of the anticipated effective date of such
transaction announced by the Company 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 the Principal Return and Net Shares, if any, 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 Notes immediately prior to the transaction. If
the consolidation, merger or binding share

                                    A-1-6



exchange to which the Company is a party also constitutes a Change in Control,
the Holder will be able to require the Company to repurchase all or a portion
of the Holder's Notes in accordance with Section 3.09 of the Indenture.

         Subject to the provisions of this paragraph 8 and the Indenture 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 10.04(c) of the Indenture, or a dividend or a
distribution described in Section 10.04(d) of the Indenture where the fair
market value of such dividend or distribution per Common Share, as determined
in the Indenture, exceeds 15% of the Sale Price of the Common Shares on the
Trading Day immediately preceding the date of declaration for such dividend or
distribution, a Holder may convert the Notes 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" date (as defined in Section 10.04(h) of the Indenture)
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" date or until the Company announces that the dividend or
distribution will not take place. No adjustment to the Conversion Price or the
ability of a Holder of Notes to convert will be made if the Company provides
that Holders will participate in the transactions without conversion.

..........A Note in respect of which a Holder has delivered a Repurchase Notice
or Change in Control Repurchase 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 Price shall be initially equal to $22.6187 per
Common Share, subject to adjustment in certain events described in the
Indenture. The Company shall pay a cash adjustment as provided in the
Indenture in lieu of any fractional Common Share.

         To convert a Note, a Holder must (1) complete and manually sign the
conversion notice below (or complete and manually sign a facsimile of such
notice) and deliver such notice to the Conversion Agent, (2) surrender the
Note to the Conversion Agent, (3) furnish appropriate endorsements and
transfer documents if required by the Conversion Agent, the Company or the
Trustee and (4) pay any transfer or similar tax, if required.

         A Holder may only convert a portion of a Note pursuant to the terms
of this paragraph 8 and in accordance with the Indenture if the principal
amount 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 Shares except as
provided herein and in the Indenture.

         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 Principal Return and Net Shares, if any, may be changed into a right to
convert it into securities, cash or other assets of the Company or another
person.

9. Conversion Arrangement on Call for Redemption.

         Any Notes called for redemption, unless surrendered for conversion
before the close of business on the Redemption Date, may be deemed to be
purchased from the Holders of such




Notes at an amount not less than the Redemption Price, by one or more
investment bankers or other purchasers who may agree with the Company to
purchase such Notes from the Holders, to convert them into Principal Return
and Net Shares, if any, of the Company and to make payment for such Notes to
the Trustee in trust for such Holders.

10. Denominations; Transfer; Exchange.

         The Notes are in fully registered form, without coupons, in
denominations of $1,000 of principal amount and integral multiples of $1,000.
A Holder may transfer or exchange Notes in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and the Company may require a Holder 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 Repurchase Notice or
Change in Control Repurchase 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.

11. Persons Deemed Owners.

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

12. 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 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.

13. Amendment; Waiver.

         Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Notes may be amended with the written consent of the
Holders of at least a majority in aggregate principal amount of the Notes at
the time outstanding and (ii) certain Defaults may be waived with the
written consent of the Holders of a majority in aggregate principal amount
of the Notes at the time outstanding. Subject to certain exceptions set
forth in the Indenture, without the consent of any Noteholder, the Company
and the Trustee may amend the Indenture or the Notes for the purposes of,
among other things, (1) adding to the Company's covenants for the benefit of
the Holders; (2) surrendering any right or power conferred upon the Company;
(3) providing for conversion rights of Holders if any reclassification or
change of Common Shares or any consolidation, merger or sale of all or
substantially all of the Company's assets occurs; (4) providing for the
assumption of the Company's obligations to the Holders in the case of a
merger, consolidation, conveyance, transfer or lease; (5) reducing the
Conversion Price, provided that the reduction will not adversely affect the
interests of Holders in any material respect; (6) complying with the
requirements of the SEC in order to effect or maintain the qualification of the


                                    A-1-8



Indenture under the TIA; (7) curing any ambiguity or correcting or
supplementing any defective provision contained in the Indenture; provided
that such modification or amendment does not adversely affect the interests of
the Holders in any material respect; (8) adding or modifying any other
provisions which the Company deems necessary or desirable and which will not
adversely affect the interests of the Holders in any material respect; (9)
complying with the provisions of the Indenture relating to when the Company
may consolidate, merge or dispose of assets; (10) providing for uncertificated
Notes in addition to Certificated Notes so long as such uncertificated Notes
are in registered form for purposes of the Internal Revenue Code of 1986, as
amended; or (11) adding to the Company's covenants or obligations under the
Indenture for the protection of Holders or surrendering any right, power or
option conferred by the Indenture on the Company.

14. Defaults and Remedies.

         Under the Indenture, Events of Default include (1) the Company fails
to pay when due the principal of or premium, if any, on any of the Notes at
maturity, upon redemption or exercise of a repurchase right or otherwise; (2)
the Company fails to pay an installment of interest (including liquidated
damages, if any) on any of the Notes that continues for 30 days after the date
when due; (3) the Company fails to deliver Principal Return and Net Shares, if
any, together with cash in lieu of fractional Common Shares, when such Common
Shares or cash in lieu of fractional Common Shares is required to be delivered
upon conversion of a Note and such failure continues for 10 days after such
delivery date; (4) the Company fails to perform or observe any other term,
covenant or agreement contained in the Notes or the Indenture for a period of
60 days after written notice of such failure, requiring the Company to remedy
the same, shall have been given to the Company by the Trustee or to the
Company and the Trustee by the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding; (5) (A) one or more defaults in the
payment of principal of or premium, if any, on any of the Company's
Indebtedness aggregating $10 million or more, when the same becomes due and
payable at the scheduled maturity thereof, and such default or defaults shall
have continued after any applicable grace period and shall not have been cured
or waived within a 30-day period after the date of such default or (B) any of
the Company's Indebtedness aggregating $10 million or more shall have been
accelerated or otherwise declared due and payable, or required to be prepaid
or repurchased (other than by regularly scheduled required prepayment) prior
to the scheduled maturity thereof and such acceleration is not rescinded or
annulled within a 30-day period after the date of such acceleration; (6) a
failure to provide timely notice of a Change in Control; (7) certain events of
bankruptcy, insolvency or reorganization with respect to the Company or any
Significant Subsidiary or any Subsidiaries of the Company which in the
aggregate would constitute a Significant Subsidiary; and (8) the filing by the
Company of a voluntary petition seeking liquidation, reorganization
arrangement, readjustment of debts or for any other relief under the
Bankruptcy Laws. If an Event of Default (other than an Event of Default
specified in clause (7) or (8) of Section 6.01 of the Indenture) occurs and is
continuing, the Trustee, or the Holders of at least 25% in aggregate principal
amount 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 Notes becoming due and payable
immediately upon the occurrence of such Events of Default.

         Noteholders 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


                                     A-1-9



reasonable indemnity or security. Subject to certain limitations, Holders of a
majority in aggregate principal amount of the Notes at the time outstanding
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Noteholders notice of any continuing Default (except a Default
in payment of amounts specified in clause (1) or (2) above) if it determines
that withholding notice is in their interests.

15. 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.

16. No Recourse Against Others.

         A director, officer, employee or shareholder, as such, of the Company
shall not have any liability for any obligations of the Company 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 accepting a Note, each Noteholder
waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Notes.

17. 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.

18. Abbreviations.

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

ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

Security Identification Procedures, the Company has caused CUSIP numbers to be

redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Notes or as contained in any
notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.
