         (d)      Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of 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 Security.

         (e)      The Company may, in the circumstances permitted by the TIA,
fix any day as the record date for the purpose of determining the Holders
entitled to give or take any request, demand, authorization, direction, notice,
consent, waiver or other action, or to vote on any action, authorized or
permitted to be given or taken by Holders. If not set by the Company prior to
the first solicitation of a Holder made by any person in respect of any such
action, or, in the case of any such vote, prior to such vote, the record date
for any such action or vote shall be the 30th day (or, if later, the date of the
most recent list of Holders required to be provided pursuant to Section 7.6)
prior to such first solicitation or vote, as the case may be. With regard to any
record date, only the Holders on such date (or their duly designated proxies)
shall be entitled to give or take, or vote on, the relevant action.

                                  ARTICLE II.

                                 THE SECURITIES

         Section 2.1 Form and Dating. The Securities and the Trustee's
certificate of authentication shall be substantially in the form of Exhibits A-1
and A-2, which are a part of this Indenture. To the extent any provisions of the
Securities and this Indenture are in conflict, the provisions of this Indenture
shall control. The Securities may have notations, legends or endorsements
required by law, stock exchange rule or usage (provided that any such notation,
legend or endorsement required by usage is in a form acceptable to the Company).
The Company shall provide any such notations, legends or endorsements to the
Trustee in writing. Each Security shall be dated the date of its authentication.

         (a)      144A Global Securities. The Securities are being offered and
sold to "qualified institutional buyers" as defined in Rule 144A ("QIBs") in
reliance on Rule 144A under the Securities Act ("Rule 144A"), and shall be
issued in the form of one or more permanent Global Securities substantially in
the form of Exhibit A-1. Such Global Securities shall be deposited on behalf of
the purchasers of the Securities represented thereby with the Trustee at its
Corporate Trust Office, as custodian for the Depositary, registered in the name
of the Depositary or a nominee of the Depositary for the accounts of
participants in the Depositary, duly executed by the Company and authenticated
by the Trustee as hereinafter provided. The aggregate principal amount of a
Global Security may from time to time be increased or decreased by adjustments
made on the records of the Trustee and the Depositary or its nominee as
hereinafter provided.

                                        10
<PAGE>
         (b)      Global Securities in General. Each Global Security shall
represent such of the outstanding Securities as shall be specified therein and
each shall provide that it shall represent the aggregate amount of outstanding
Securities from time to time endorsed thereon and that the aggregate amount of
outstanding Securities represented thereby may from time to time be reduced or
increased, as appropriate, to reflect exchanges, redemptions, repurchases and
conversions.

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

         (c)      Book-Entry Provisions. This Section 2.1(c) shall apply only
to Global Securities deposited with or on behalf of the Depositary.

         The Company shall execute and the Trustee shall, in accordance with
this Section 2.1(c), authenticate and deliver initially one or more Global
Securities that (a) shall be registered in the name of the Depositary, (b) shall
be 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 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 SECURITY SHALL BE LIMITED TO
                  TRANSFERS TO NOMINEES OF THE DEPOSITORY TRUST COMPANY OR TO A
                  SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF
                  PORTIONS OF THIS GLOBAL SECURITY 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."

         (d)      Certificated Securities. In the event that the Securities are
issued as Certificated Securities, including pursuant to Section 2.12(a)(ii),
such Securities will be issued substantially in the form of Exhibit A-2 attached
hereto.

                                       11
<PAGE>
         Section 2.2 Execution and Authentication. The Securities shall be
executed on behalf of the Company by any Officer. The signature of the
Officer on the Securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at the time of the execution of the Securities 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 Securities or did not hold such offices at the date of authentication of
such Securities.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security 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 Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

         The Trustee shall authenticate and deliver the Securities for original
issue in an aggregate principal amount of up to $150,000,000 upon one or more
Company Orders without any further action by the Company. The aggregate
principal amount of the Securities due at the Stated Maturity thereof
outstanding at any time may not exceed the amount set forth in the foregoing
sentence, except as provided in Section 2.7.

         The Securities shall be issued only in registered form without coupons
and only in denominations of $1,000 of principal amount and any integral
multiple thereof.

         Section 2.3 Registrar, Paying Agent and Conversion Agent. The Company
shall maintain an office or agency where Securities may be presented for
registration of transfer or for exchange ("Registrar"), an office or agency
where Securities may be presented for purchase or payment ("Paying Agent") and
an office or agency where Securities may be presented for conversion
("Conversion Agent"). The Registrar shall keep a register of the Securities and
of their transfer and exchange. The Company may have one or more co-registrars,
one or more additional Paying Agents and one or more additional conversion
agents. The term Paying Agent includes any additional Paying Agent, including
any named pursuant to Section 4.5. The term Conversion Agent includes any
additional conversion agent, including any named pursuant to Section 4.5.

         The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent, Conversion Agent or co-registrar (that is not also 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 7.7. 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 Securities.

                                        12
<PAGE>
         Section 2.4 Paying Agent and Trustee To Hold Money in Trust. Except as
otherwise provided herein, on or prior to each due date of payments in respect
of any Security, 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 Securityholders or the Trustee all money held
by the Paying Agent for the making of payments in respect of the Securities 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.

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

         Section 2.5 Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to
it of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall cause the Registrar to furnish to the Trustee at
least semiannually on January 15 and July 15 a listing of Securityholders 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
Securityholders.

         Section 2.6 Transfer and Exchange.

         (a)      Subject to Section 2.12 hereof, upon surrender for
registration of transfer of any Security, together with a written instrument of
transfer satisfactory to the Registrar duly executed by the Securityholder or
such Securityholder's attorney duly authorized in writing, at the office or
agency of the Company designated as Registrar or co-registrar pursuant to
Section 2.3, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denomination or denominations, of a like
aggregate principal amount. 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
Securities from the Securityholder requesting such transfer or exchange.

         At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denomination or denominations, of a like aggregate
principal amount, upon surrender of the Securities to be exchanged, together
with a written instrument of transfer satisfactory to the Registrar duly
executed by the Securityholder or such Securityholder's attorney duly

                                        13
<PAGE>
authorized in writing, at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities, 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 Securities selected for redemption (except,
in the case of Securities to be redeemed in part, the portion thereof not to be
redeemed) or any Securities in respect of which a Purchase Notice or Fundamental
Change Purchase Notice has been given and not withdrawn by the Holder thereof in
accordance with the terms of this Indenture (except, in the case of Securities
to be purchased in part, the portion thereof not to be purchased) or any
Securities for a period of 15 days before the mailing of a notice of redemption
of Securities to be redeemed.

         The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Security other than to require delivery of such certificates and other
documentation or evidence as are expressly required by, and to do so if and when
expressly required by the terms of, this Indenture, and to examine the same to
determine substantial compliance as to form with the express requirements
hereof.

         (b)      Notwithstanding any provision to the contrary herein, so long
as a Global Security remains outstanding and is held by or on behalf of the
Depositary, transfers of a Global Security, in whole or in part, shall be made
only in accordance with Section 2.12 and this Section 2.6(b); provided, however,
that beneficial interests in a Global Security may be transferred to persons who
take delivery thereof in the form of a beneficial interest in the Global
Security in accordance with the transfer restrictions set forth under the
heading "Transfer Restrictions" in the offering memorandum relating to the
Securities dated November 18, 2002 and, if applicable, in the Legend.

         Except for transfers or exchanges made in accordance with Section 2.12,
transfers of a Global Security shall be limited to transfers of such Global
Security in whole, but not in part, to nominees of the Depositary or to a
successor of the Depositary or such successor's nominee.

         In the event that a Global Security is exchanged for Securities in
definitive form pursuant to Section 2.12 prior to the effectiveness of a Shelf
Registration Statement with respect to such Securities, such exchange may occur,
and such Securities may be further exchanged or transferred, only upon receipt
by the Registrar of (1) such Global Security or such Securities in definitive
form, duly endorsed as provided herein, as applicable, (2) instructions from the
holder directing the Trustee to authenticate and deliver one or more Securities
in definitive form of the same aggregate principal amount as the Global Security
or the Securities in definitive form (or portion thereof), as applicable, to be
transferred, such instructions to contain the name or names of the designated
transferee or transferees, the authorized denomination or denominations of the
Securities in definitive form to be so issued and appropriate delivery
instructions, and (3) such certifications or other information and, in the case
of transfers pursuant to Rule 144 under the Securities Act, legal opinions as
the Company may reasonably require to confirm that such transfer is being made
pursuant to an exemption from, or in a transaction not subject to, the
registration requirements of the Securities Act (including the certification
requirements intended to ensure that such transfers comply with Rule 144A under
the Securities Act), and upon

                                        14
<PAGE>
compliance with such other procedures as may from time to time be adopted by the
Company and the Registrar.

         (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 Securities.

         (d)      Any Registrar appointed pursuant to Section 2.3 hereof shall
provide to the Trustee such information as the Trustee may reasonably require in
connection with the delivery by such Registrar of Securities upon transfer or
exchange of Securities.

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

         (f)      Except for transfers in connection with a Shelf Registration
Statement, if Securities are issued upon the transfer, exchange or replacement
of Securities subject to restrictions on transfer and bearing the legends set
forth on the forms of Security attached hereto as Exhibits A-1 and A-2 setting
forth such restrictions (collectively, the "Legend"), or if a request is made to
remove the Legend on a Security, the Securities so issued shall bear the Legend,
or the Legend shall not be removed, as the case may be, unless there is
delivered to the Company and the Registrar such satisfactory evidence (which may
include a legal opinion), as may be reasonably required by the Company and the
Registrar, that neither the Legend nor the restrictions on transfer set forth
therein are required to ensure that transfers thereof comply with the provisions
of Rule 144A or Rule 144 under the Securities Act or that such Securities are
not "restricted" within the meaning of Rule 144 under the Securities Act. Upon
(i) provision of such satisfactory evidence, or (ii) notification by the Company
to the Trustee and Registrar of the sale of such Security pursuant to a
registration statement that is effective at the time of such sale, the Trustee,
at the written direction of the Company, shall authenticate and deliver a
Security that does not bear the Legend. If the Legend is removed from the face
of a Security and the Security is subsequently held by the Company or an
Affiliate of the Company, the Legend shall be reinstated.

         (g)      Anything to the contrary herein notwithstanding, the Company
and the Trustee may impose such transfer, certification, exchange or other
requirements, and require such restrictive legends on certificates evidencing
the Securities, as (i) they may determine are necessary to ensure compliance
with the securities laws of the United States and the states therein and any
other applicable laws, (ii) to ensure that the Shelf Registration Statement or
amendment thereto covering the Securities or shares of Common Stock to be issued
upon conversion of the Securities is declared effective by the Commission or
(iii) as the Depositary may require.

         Section 2.7 Replacement Securities. If (a) any mutilated Security 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 Security, and
there is delivered to the Company and the Trustee such security 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 Security has been acquired by a

                                        15
<PAGE>
protected purchaser as defined in the New York Uniform Commercial Code, the
Company shall execute and upon its written request the Trustee shall
authenticate and deliver, in exchange for any such mutilated Security or in lieu
of any such destroyed, lost or stolen Security, a new Security of like tenor and
principal amount, bearing a certificate number not contemporaneously
outstanding.

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

         Upon the issuance of any new Securities under this Section 2.7, 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 Security issued pursuant to this Section 2.7 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security 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 Securities duly issued hereunder.

         The provisions of this Section 2.7 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 Securities.

         Section 2.8 Outstanding Securities; Determinations of Holders' Action.
Securities outstanding at any time are all the Securities authenticated by the
Trustee except for those cancelled by it, those paid pursuant to Section 2.7,
those delivered to it for cancellation and those described in this Section 2.8
as not outstanding. A Security does not cease to be outstanding because the
Company or an Affiliate thereof holds the Security; provided, however, that in
determining whether the Holders of the requisite principal amount of Securities
have given or concurred in any request, demand, authorization, direction,
notice, consent, waiver or other Act hereunder, Securities owned by the Company
or any other obligor upon the Securities 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,
waiver or other Act, only Securities which a Responsible Officer of the Trustee
actually knows to be so owned shall be so disregarded. Subject to the
foregoing, only Securities outstanding at the time of such determination shall
be considered in any such determination (including, without limitation,
determinations pursuant to Articles VI and IX).

         If a Security is replaced pursuant to Section 2.7, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a protected purchaser.

                                       16
<PAGE>
         If the Paying Agent holds, in accordance with this Indenture, on a
Redemption Date, or on the Business Day following a Purchase Date or a
Fundamental Change Purchase Date, or on Stated Maturity, money sufficient to pay
Securities payable on that date, then immediately after such Redemption Date,
Purchase Date, Fundamental Change Purchase Date or Stated Maturity, as the case
may be, such Securities shall cease to be outstanding and interest, if any, on
such Securities shall cease to accrue; provided, however, that if such
Securities 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 Security is converted in accordance with Article X, then from and
after the Conversion Date, such Security shall cease to be outstanding and
interest, if any, shall cease to accrue on such Security.

         Section 2.9 Temporary Securities. Pending the preparation of definitive
Securities, the Company may execute, and upon Company Order the
Trustee shall authenticate and deliver, temporary Securities which
are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued and
with such appropriate insertions, omissions, substitutions and other
variations as the Officers executing such Securities may determine,
as conclusively evidenced by their execution of such Securities.

         If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at the office
or agency of the Company designated for such purpose pursuant to Section 2.3,
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations. Until so exchanged the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

         Section 2.10 Cancellation. All Securities surrendered for payment,
purchase by the Company pursuant to Article III, 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
Securities previously authenticated and delivered hereunder that the Company may
have acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee. The Company may not issue new Securities to
replace Securities it has paid or delivered to the Trustee for cancellation or
that any Holder has converted pursuant to Article X. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section 2.10, except as expressly permitted by this Indenture. All
cancelled Securities held by the Trustee shall be disposed of by the Trustee in
accordance with the Trustee's customary procedure.

         Section 2.11 Persons Deemed Owners. Prior to due presentment of a
Security 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 Security is registered in the records of the Registrar as

                                       17
<PAGE>
the owner of such Security for the purpose of receiving payment of principal of
the Security or the payment of any Redemption Price, Purchase Price or
Fundamental Change Purchase Price in respect thereof, and interest thereon, for
the purpose of conversion and for all other purposes whatsoever, whether or not
such Security 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 Securities. (a) Notwithstanding any other
provisions of this Indenture or the Securities, (A) transfers of a Global
Security, in whole or in part, shall be made only in accordance with Section
2.6(b) and Section 2.12(a)(i), (B) transfers of a beneficial interest in a
Global Security for a Certificated Security shall comply with Section 2.6 and
Section 2.12(a)(ii) below, and (C) transfers of a Certificated Security shall
comply with Section 2.6 and Sections 2.12(a)(iii) and (iv) below.

                           (i)      Transfer of Global Security. A Global
         Security may not be transferred, in whole or in part, to any person
         other than the Depositary or one or more nominees or any successor
         thereof, and no such transfer to any such other person may be
         registered; provided, however, that this clause (i) shall not prohibit
         any transfer of a Security that is issued in exchange for a Global
         Security but is not itself a Global Security. No transfer of a Security
         to any person shall be effective under this Indenture or the Securities
         unless and until such Security 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 Security
         effected in accordance with the other provisions of this Section
         2.12(a).

                           (ii)     Restrictions on Transfer of a Beneficial
         Interest in a Global Security for a Certificated Security. A beneficial
         interest in a Global Security may not be exchanged for a Certificated
         Security except upon the circumstances contemplated in Section
         2.12(e)(1) below and additionally, upon satisfaction of the
         requirements set forth below. Upon receipt by the Trustee of a transfer
         of a beneficial interest in a Global Security in accordance with
         Applicable Procedures for a Certificated Security in the form
         satisfactory to the Trustee, together with:

                                    (A)     so long as the Securities are
                                    Restricted Securities, certification in the
                                    form set forth in Exhibit B,

                                    (B)     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 Security to reflect a
                                    decrease in the aggregate principal amount
                                    of the Securities represented by the Global
                                    Security, such instructions to contain
                                    information regarding the Depositary account
                                    to be credited with such decrease, and

                                    (C)     if the Company so requests, an
                                    opinion of counsel or other evidence
                                    reasonably satisfactory to it as to the
                                    compliance with the restrictions set forth
                                    in the Legend,

                                       18

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 the Securities represented by the
Global Security to be decreased by the aggregate principal amount of the
Certificated Security to be issued, shall issue such Certificated Security and
shall debit or cause to be debited to the account of the person specified in
such instructions a beneficial interest in the Global Security equal to the
principal amount of the Certificated Security so issued.

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

                           (y)     to register the transfer of such
                  Certificated Securities; or

                           (z)     to exchange such Certificated Securities for
                  an equal principal amount of Certificated Securities 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 Securities surrendered for transfer or exchange:

(1)      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; and

(2)      so long as such Securities are Restricted Securities, such Securities
         are being transferred or exchanged pursuant to an effective
         registration statement under the Securities Act or pursuant to clause
         (A), (B) or (C) below, and are accompanied by the following additional
         information and documents, as applicable:

         (A)      if such Certificated Securities are being transferred to the
                  Company, a certification to that effect; or

         (B)      if such Certificated Securities are being delivered to the
                  Registrar by a Holder for registration in the name of such
                  Holder, without transfer, a certification from such Holder to
                  that effect; or

         (C)      if such Certificated Securities are being transferred pursuant
                  to an exemption from registration, (i) a certification to that
                  effect (in the form set forth in Exhibit B, if applicable) and
                  (ii) if the Company so requests, an opinion of counsel or
                  other evidence reasonably satisfactory to it as to the
                  compliance with the restrictions set forth in the Legend.

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

                                       19
<PAGE>
                  Upon receipt by the Trustee of a Certificated Security, duly
         endorsed or accompanied by appropriate instruments of transfer, in form
         satisfactory to the Trustee, together with:

                  (I)      so long as the Securities are Restricted Securities,
         certification, in the form set forth in Exhibit B, that such
         Certificated Security is being transferred in accordance with Rule 144A
         or Rule 144; and

                  (II)     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 Security to reflect an increase in
         the aggregate principal amount of the Securities represented by the
         Global Security, such instructions to contain information regarding the
         Depositary account to be credited with such increase, then the Trustee
         shall cancel such Certificated Security 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 Securities represented by the Global
         Security to be increased by the aggregate principal amount of the
         Certificated Security 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 Security equal to the principal
         amount of the Certificated Security so cancelled. If no Global
         Securities are then outstanding, the Company shall issue and the
         Trustee shall authenticate, upon receipt of a Company Order, a new
         Global Security in the appropriate principal amount.

         (b)      Subject to Section 2.12(c), every Security shall be subject to
the restrictions on transfer provided in the Legend. Whenever any Restricted
Security is presented or surrendered for registration of transfer or for
exchange for a Security registered in a name other than that of the Holder, such
Security must be accompanied by a certificate in substantially the form set
forth in Exhibit B, dated the date of such surrender and signed by the Holder of
such Security, as to compliance with such restrictions on transfer. The
Registrar shall not be required to accept for such registration of transfer or
exchange any Security not so accompanied by a properly completed certificate.

         (c)      The restrictions imposed by the Legend upon the
transferability of any Security shall cease and terminate when such Security has
been sold pursuant to an effective registration statement under the Securities
Act or transferred in compliance with Rule 144 under the Securities Act (or any
successor provision thereto) or, if earlier, upon the expiration of the holding
period applicable to sales thereof under Rule 144(k) under the Securities Act
(or any successor provision). Any Security as to which such restrictions on
transfer shall have expired in accordance with their terms or shall have
terminated may, upon a surrender of such Security for exchange to the Registrar
in accordance with the provisions of this Section 2.12 (accompanied, in the
event that such restrictions on transfer have terminated by reason of a transfer
in compliance with Rule 144 or any successor provision, by an opinion of counsel
addressed to the Company and in form acceptable to the Company, to the effect
that the transfer of such Security has been made in compliance with Rule 144 or
such successor provision), be exchanged for a new Security, of like tenor and
aggregate principal amount, which shall not bear the restrictive Legend. The
Company shall inform the Trustee of the effective date of any registration
statement registering the resale of the Securities under the Securities Act. The
Trustee shall not

                                       20
<PAGE>
be liable for any action taken or omitted to be taken by it in
good faith in accordance with the aforementioned opinion of counsel or
registration statement.

         (d)      As used in the Section 2.12(b) and (c), the term "transfer"
encompasses any sale, pledge, transfer, loan, hypothecation, or other
disposition of any Security.

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

         (1)      Notwithstanding any other provisions of this Indenture or the
                  Securities, a Global Security shall not be exchanged in whole
                  or in part for a Security registered in the name of any person
                  other than the Depositary or one or more nominees or any
                  successor thereof; provided, however, that a Global Security
                  may be exchanged for Securities registered in the names 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 Security 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, (ii) an Event
                  of Default has occurred and is continuing with respect to the
                  Securities or (iii) the Company in its sole discretion elects
                  not to have the Securities represented by a Global Security
                  and to cause the issuance of Certificated Securities. Any
                  Global Security exchanged pursuant to clause (i) or (iii)
                  above shall be so exchanged in whole and not in part, and any
                  Global Security exchanged pursuant to clause (ii) above may be
                  exchanged in whole or from time to time in part as directed by
                  the Depositary. Any Security issued in exchange for a Global
                  Security or any portion thereof shall be a Global Security;
                  provided, however, that any such Security so issued that is
                  registered in the name of a person other than the Depositary
                  or a nominee thereof shall not be a Global Security and shall
                  be deemed a Certificated Security.

         (2)      Securities issued in exchange for a Global Security 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
                  Security or portion thereof to be so exchanged, shall be
                  registered in such names and be in such authorized
                  denominations as the Depositary shall designate and shall bear
                  the applicable legends provided for herein. Any Global
                  Security to be exchanged in whole shall be surrendered by the
                  Depositary to the Trustee, as Registrar. With regard to any
                  Global Security to be exchanged in part, either such Global
                  Security 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 Security, 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 Security issuable on such exchange to or upon the
                  order of the Depositary or an authorized representative
                  thereof.

                                       21
<PAGE>
         (3)      Subject to the provisions of clause (5) below, the registered
                  Holder may grant proxies and otherwise authorize any person,
                  including Agent Members 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 Securities.

         (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 Securities
                  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 Security registered
                  in the name of the Depositary or any nominee thereof, or under
                  any such Global Security, 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 Security for all purposes
                  whatsoever. Notwithstanding the foregoing, nothing herein
                  shall 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 impair, as
                  between the Depositary, its Agent Members and any other person
                  on whose behalf an Agent Member may act, the operation of
                  customary practices of such persons governing the exercise of
                  the rights of a holder of any Security.

         Section 2.13 CUSIP Numbers. The Company may issue the Securities with
one or more "CUSIP," "ISIN" and "CINS" numbers (if then generally in use), and,
if so, the Trustee shall use "CUSIP," "ISIN" and "CINS" numbers in notices of
redemption as a convenience to Holders; provided, however, that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, 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," "ISIN" and "CINS"
numbers.

         Section 2.14 Ranking. The Debt of the Company arising under or in
connection with this Indenture and every outstanding Security issued under this
Indenture from time to time constitutes and will constitute a subordinated
unsecured obligation of the Company, ranking equally with other existing and
future subordinated unsecured Debt of the Company.

         Section 2.15 Opinion of Counsel. Any provision in this Indenture that
permits the Company to require an opinion of counsel in respect of any
securities transfer, such counsel shall have substantial experience in practice
under the Securities Act and otherwise be reasonably acceptable to the Company.

                                  ARTICLE III.

                            REDEMPTION AND PURCHASES

         Section 3.1 Company's Right To Redeem; Notices to Trustee. Beginning on
October 18, 2007, the Company, at its option, may redeem, in accordance with
the provisions of Paragraph 5 of the Securities, the Securities, in whole or in
part, for cash at a redemption price equal to 100% of the principal amount of
the Securities to be redeemed plus accrued and unpaid interest thereon to, but
excluding, the Redemption Date (the "Redemption Price"). If the Company elects
to redeem Securities pursuant to Paragraph 5 of the Securities, it shall notify
the Trustee in writing of the Redemption Date, the principal amount of
Securities to be redeemed and the Redemption Price. The Company shall give the
notice to the Trustee provided for in Section 3.3 by a Company Order, at least
40 days before the Redemption Date (unless a shorter notice shall be
satisfactory to the Trustee). The Company may not redeem the Securities if it
has failed to pay any interest on the Securities, and such failure to pay
interest is continuing.

         Section 3.2 Selection of Securities To Be Redeemed. If less than all
the Securities are to be redeemed, unless the procedures of the Depositary
provide otherwise, the Trustee shall select the Securities to be redeemed by
lot, on a pro rata basis or by another method the Trustee considers fair and
appropriate (so long as such method is not prohibited by the rules of any stock
exchange on which the Securities are then listed). The Trustee shall make the
selection at least 35 days but not more than 60 days before the Redemption Date
from outstanding Securities not previously called for redemption. The Trustee
may select for redemption portions of the principal amount of Securities that
have denominations larger than $1,000. Securities and portions of Securities
that the Trustee selects shall be in principal amounts of $1,000 or an integral
multiple of $1,000, if less than all of the Securities are being redeemed.
Provisions of this Indenture that apply to Securities called for redemption
also apply to portions of Securities called for redemption. The Trustee shall
notify the Company promptly of the Securities or portions of the Securities to
be redeemed. If any Security selected for partial redemption is converted in
part before termination of the conversion right with respect to the portion of
the Security so selected, the converted portion of such Security shall be
deemed (so far as may be) to be the portion selected for redemption.
Securities, which have been converted during a selection of Securities to be
redeemed, may be treated by the Trustee as outstanding for the purpose of such
selection.

         Section 3.3 Notice of Redemption. At least 30 days but not more than 60
days before a Redemption Date, the Company shall mail a notice of redemption by
first-class mail, postage prepaid, to each Holder of Securities to be redeemed.
The notice shall identify the Securities to be redeemed and shall state:

         (1)      the Redemption Date;

         (2)      the Redemption Price;

         (3)      the Conversion Rate;

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

                                       23
<PAGE>
         (5)      that Securities called for redemption may be converted at any
                  time before the close of business on the Business Day
                  immediately preceding the Redemption Date, unless the Company
                  defaults in making the payment due on the Redemption Date, in
                  which case the conversion right shall terminate at the close
                  of business on the date such default is cured and such payment
                  is made;

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

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

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

         (9)      the CUSIP, ISIN and CINS number(s) (as applicable) of the
                  Securities.

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense, provided that the
Company makes such request at least five Business Days prior to the date by
which such notice of redemption must be given to Holders in accordance with this
Section 3.3 unless a shorter period is agreed upon by the Trustee.

         Section 3.4 Effect of Notice of Redemption. Once notice of redemption
is given, Securities called for redemption become due and payable on the
Redemption Date and at the Redemption Price stated in the notice except for
Securities which are converted in accordance with the terms of this Indenture.
Upon surrender to the Paying Agent, such Securities shall be paid at the
Redemption Price stated in the notice.

         Section 3.5 Deposit of Redemption Price. Prior to 11:00 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 Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption which on or prior
thereto have been delivered by the Company to the Trustee for cancellation or
have been converted. The Paying Agent shall as promptly as practicable return
to the Company any money not required for that purpose because of conversion of
Securities pursuant to Article X. 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 3.6 Securities Redeemed in Part. Upon surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Security in an authorized
denomination equal in principal amount to the unredeemed portion of the
Security surrendered.

         Section 3.7 Purchase of Securities by the Company at Option of the
Holder.

         (a)      General. Securities shall be purchased by the Company for cash

October 15, 2007, October 15, 2012, October 15, 2017, October 15, 2022 and
October 15, 2027 (each, a "Purchase Date"), at 100.0% of the principal amount
thereof plus accrued and unpaid interest thereon, if any, to, but excluding,
such Purchase Date (the "Purchase Price"). Purchases of Securities hereunder
shall be made, at the option of the Holder thereof, upon:

         (1)      delivery to the Paying Agent by the Holder of a written notice
                  of purchase (a "Purchase Notice") during the period beginning
                  at any time from the opening of business on the date that is
                  20 Business Days prior to the relevant Purchase Date until
                  11:00 a.m. (New York City time) on such Purchase Date stating:

                  (A)      the certificate number of the Security which the
                           Holder will deliver to be purchased or the
                           appropriate Depositary procedures if Certificated
                           Securities have not been issued,

                  (B)      the portion of the principal amount of the Security

                           Purchase Notice has been given may be converted if
                           they are otherwise convertible pursuant to Article X
                           hereof only if the Fundamental Change Purchase Notice
                           has been withdrawn in accordance with the terms of
                           this Indenture;

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

                  (9)      that the Fundamental Change Purchase Price for any

                           Change Purchase Date and the time of surrender of

                           Purchase Notice;

                  (12)     that, unless the Company defaults in making payment
                           of such Fundamental Change Purchase Price, interest,
                           if any, on Securities surrendered for purchase by the
                           Company will cease to accrue on and after the
                           Fundamental Change Purchase Date; and

                  (13)     the CUSIP, ISIN and CINS number(s) (as applicable) of
                           the Securities.

         At the Company's request, the Trustee shall give the notice of the
Fundamental Change in the Company's name and at the Company's expense, provided
that the Company makes such request at least five Business Days prior to the
date by which such notice of the Fundamental Change must be given to Holders in
accordance with this Section 3.8 unless a shorter period is agreed upon by the
Trustee.

                           which the Holder will deliver to be purchased, which
                           portion, if not the entire amount of the Security,
                           must be $1,000 or an integral multiple thereof; and

                  (3)      that such Security shall be purchased pursuant to the
                           terms and conditions specified in Paragraph 7(b) of

prescribe) which the Company is required to file with the SEC pursuant to
Section 13 or 15(d) of the Exchange Act. In the event the Company is at any

information as is specified pursuant to Rule 144A(d)(4) under the Securities
Act. Whether a person is a beneficial owner shall be determined by the Company
to the Company's reasonable satisfaction.

         Section 4.8 Notice of Liquidated Damages Amount. If any Liquidated
Damages Amount is payable by the Company pursuant to the Registration Rights
Agreement, the Company shall deliver to the Trustee a certificate to that
effect stating (i) the amount of such Liquidated Damages Amount that is payable
and (ii) the date on which such Liquidated Damages Amount is payable. Unless
and until a Responsible Officer of the Trustee receives such a certificate, the
Trustee may assume without inquiry that no Liquidated Damages Amount is
payable. If the Company has paid any Liquidated Damages Amount directly to the
person(s) entitled to such amount, the Company shall deliver to the Trustee a
certificate setting forth the particulars of such payment.

                                   ARTICLE V.

                          CONSOLIDATION, MERGER OR SALE

         Section 5.1 Consolidation, Merger or Sale. The Company covenants and
agrees that it will not consolidate or merge with or into any other person, or
convey, transfer or lease its property and assets substantially as an entirety
to any other person, unless (a) the Company is the surviving person, or the
resulting, surviving or transferee person, if other than the Company, is
organized and existing under the laws of the United States, any state thereof
or the District of Columbia, or any other country, (b) the successor person
assumes all of the Company's obligations under the Securities and this
Indenture, and (c) immediately after giving effect to the transaction no
Default shall have occurred and be continuing.

         Section 5.2 Securities and Indenture To Be Assumed by Successor on
Consolidation, Merger or Sale. Subject to the provisions of Section 5.1,
nothing in this Indenture shall prevent any consolidation or merger of the
Company with or into any other person, or any conveyance, transfer or lease of
the property and assets of the Company to any other person lawfully entitled to
acquire the same; provided, however, and the Company covenants and agrees, that
any such consolidation, merger, conveyance, transfer or lease shall be upon the
condition that the due and punctual payment of the principal, premium, if any,
and interest of all the Securities according to their tenor, and the due and
punctual performance and observance of all the terms, covenants and conditions
of the Indenture to be kept or performed by the Company shall, by an indenture
supplemental hereto, executed and delivered to the Trustee, be assumed by the
person formed by or resulting from any such consolidation or merger (provided
that no such supplemental indenture shall be required if the Company is the
surviving person upon the consolidation or merger), or which shall have
received the transfer of all or substantially all of the property and assets of
the Company, just as fully and effectually as if such successor person had been
the original party of the first part hereto. Every such successor person upon
executing an indenture supplemental hereto, as provided in this Section 5.2, in
form satisfactory to the Trustee, shall succeed to and be substituted for the
Company with the same effect as if it had been named herein as party of the
first part hereto; and any order, certificate, statement, request,
instructions, advice or resolutions of the Board of Directors or officers of
the Company provided for in this Indenture may be made by like officials of
such successor person.

                                       33
<PAGE>
         In case of any such consolidation, merger, conveyance, transfer or
lease such changes in phraseology and form (but not in substance) may be made in
the Securities thereafter to be issued as may be appropriate.

         In the event of any such conveyance or transfer (other than a transfer
by way of lease), the Company or any successor person which shall theretofore
have become such in the manner described in this Article V shall be discharged
from all obligations and covenants under this Indenture and the Securities.

         Subject to the provisions of Section 7.1, the Trustee may receive an
Opinion of Counsel as conclusive evidence that any such indenture supplemental
hereto complies with the foregoing conditions and provisions of this Section
5.2.

         This Section 5.2 shall be applicable to successive consolidations or
mergers to which the Company (including any successor) is a party and to
successive sales or transfers by the Company (including any successor).

                                  ARTICLE VI.

                              DEFAULTS AND REMEDIES

         Section 6.1 Events of Default. An "Event of Default" occurs if:

         (1)      the Company defaults in the payment of the principal amount or
premium, if any, on any Security when the same becomes due and payable upon
redemption or otherwise, whether or not the payment is prohibited by the
provisions of Article XI hereof; or

         (2)      the Company defaults in the payment of any accrued and unpaid
interest or Liquidated Damages Amounts, if any, when due and payable, and
continuance of such default for a period of 30 days, whether or not the payment
is prohibited by the provisions of Article XI hereof; or

         (3)      the Company fails to comply in any material respect with any
of its agreements or covenants in the Securities or this Indenture (other than
those referred to in clause (1) or (2) above) and such failure continues for 60
days after receipt by the Company of a Notice of Default; or

         (4)      the entry by a court having jurisdiction in the premises of
(A) a decree or order for relief in respect of the Company or any Significant
Subsidiary in an involuntary case or proceeding under any applicable federal or
state bankruptcy, insolvency, reorganization or other similar law or (B) a
decree or order adjudging the Company or any Significant Subsidiary as bankrupt
or insolvent, or approving as properly filed a petition by one or more persons
other than the Company or any Significant Subsidiary seeking reorganization,
arrangement, adjustment or composition of or in respect of the Company or any
Significant Subsidiary under any applicable federal or state law, or appointing
a custodian, receiver, liquidator, assignee, trustee, sequestrator or other
similar official for the Company or any Significant Subsidiary or for all or
substantially all of their respective property, or ordering the winding up or
liquidation of their respective affairs, and the continuance of any such decree
or order for relief or any such other decree or order unstayed and in effect for
a period of 90 consecutive days; or

                                       34
<PAGE>
         (5)      the commencement by the Company or any Significant Subsidiary
of a case or proceeding under any applicable federal or state bankruptcy,
insolvency, reorganization or other similar law or of any other case or
proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to
the entry of a decree or order for relief in respect of the Company or any
Significant Subsidiary in a case or proceeding under any applicable federal or
state bankruptcy, insolvency, reorganization or other similar law or to the
commencement of any bankruptcy or insolvency case or proceeding against it, or
the filing by it of a petition or answer or consent seeking reorganization or
relief under any applicable federal or state law, or the consent by any of them
to the filing of such petition or to the appointment of or taking possession by
a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar
official of the Company or any Significant Subsidiary or of all or substantially
all of their respective property, or the making by any of them of an assignment
for the benefit of creditors, or the admission by any of them in writing of
their respective inability to pay their respective debts generally as they
become due, or the taking of corporate action by the Company or any Significant
Subsidiary in furtherance of any such action.

         A Default under clause (3) 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 Securities 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 (3) 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 shall deliver to the Trustee, within 30 days after it
becomes aware of the occurrence thereof, written notice of any Event of Default
under clause (4) or (5) above or any Default, its status and what action the
Company is taking or proposes to take with respect thereto.

         Section 6.2 Acceleration. If an Event of Default (other than an Event
of Default specified in Section 6.1(4) or (5)) occurs and is continuing, the
Trustee by notice to the Company, or the Holders of at least 25% in aggregate
principal amount of the Securities at the time outstanding by notice to the
Company and the Trustee, may declare the principal amount, premium, if any,
plus accrued and unpaid interest and Liquidated Damages Amount, if any, on all
the outstanding Securities to be immediately due and payable.

         Upon such a declaration, such accelerated amount shall be due and
payable immediately. If an Event of Default specified in Section 6.1(4) or (5)
occurs and is continuing, the principal amount, premium, if any, plus accrued
and unpaid interest and Liquidated Damages Amount, if any, on all the Securities
shall become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Securityholders. The Holders of a majority
in aggregate principal amount of the Securities at the time outstanding, by
notice to the Trustee (and without notice to any other Securityholder) may
rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default have
been cured or waived except nonpayment of the principal amount plus accrued and
unpaid interest, if any, that have become due solely as a result of acceleration
and if all amounts due to the Trustee under Section 7.7 have been paid. No such
rescission shall affect any subsequent Default or impair any right consequent
thereto.

                                       35
<PAGE>
         Section 6.3 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 amount, premium, if any, plus accrued and unpaid interest and
Liquidated Damages Amount, if any, on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.

         The Trustee may maintain a proceeding even if the Trustee does not
possess any of the Securities or does not produce any of the Securities in the
proceeding. A delay or omission by the Trustee or any Securityholder 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 6.4 Waiver of Past Defaults. The Holders of a majority in
aggregate principal amount of the Securities at the time outstanding, by notice
to the Trustee (and without notice to any other Securityholder), may waive an
existing Default and its consequences except (a) an Event of Default described
in Section 6.1(1) or (2), or (b) a Default in respect of a provision that under
Section 9.2 cannot be amended without the consent of each Securityholder
affected. 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 6.4 shall be in lieu of Section 316(a)(1)(B) of the TIA and such Section
316(a)(1)(B) is hereby expressly excluded from this Indenture, as permitted by
the TIA.

         Section 6.5 Control by Majority. The Holders of a majority in aggregate
principal amount of the Securities 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 Securityholders or would involve the Trustee
in personal liability unless the Trustee is offered indemnity satisfactory to
it. This Section 6.5 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 6.6 Limitation on Suits. A Securityholder may not pursue any
remedy with respect to this Indenture, except in the case of a default in the
payment of principal amount, premium, if any, plus accrued and unpaid interest
and Liquidated Damages Amount, if any, or the Securities 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 Securities at the time outstanding make a written request to the Trustee
to pursue the remedy and offer to the Trustee security or indemnity reasonably
satisfactory to the Trustee against any loss, liability or expense;

         (3)      the Trustee does not receive an inconsistent direction from
the holders of a majority in principal amount of the debentures; and

                                       36
<PAGE>
         (4)      the Trustee does not comply with the request within 60 days
after receipt of such notice, request and offer of security or indemnity.

         A Securityholder may not use this Indenture to prejudice the rights of
any other Securityholder or to obtain a preference or priority over any other
Securityholder.

         Section 6.7 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 of the Securities, premium, if any, plus accrued and unpaid
interest and the Liquidated Damages Amount, if any, in respect of the Securities
held by such Holder, on or after the respective due dates expressed in the
Securities or any Redemption Date, and to convert the Securities in accordance
with Article X, 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.

         Section 6.8 Collection Suit by Trustee. If an Event of Default
described in Section 6.1(1) 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 Securities and the amounts
provided for in Section 7.7.

         Section 6.9 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 Securities or
the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal amount of the Securities plus
accrued and unpaid interest in respect of the Securities 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 of the Securities plus accrued and unpaid 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 7.7) 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 to 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 7.7.

         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,

                                       37
<PAGE>
adjustment or composition affecting the Securities 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:

                 FIRST: to the Trustee for amounts due under Section 7.7;

                 SECOND: to Securityholders for amounts due and unpaid on the
         Securities for the principal amount of the Securities, premium, if any,
         plus accrued and unpaid interest and Liquidated Damages Amount, if any,
         ratably, without preference or priority of any kind, according to such
         amounts due and payable on the Securities; and

                  THIRD: the balance, if any, to the Company.

         The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10. At least 15 days before such
record date, the Trustee shall mail to each Securityholder 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 6.7 or a suit by Holders of more than 10% in aggregate
principal amount of the Securities 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 of
the Securities plus accrued and unpaid interest 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.

         Section 7.1 Duties of Trustee.

         (a)      If an Event of Default has occurred and is continuing, the
Trustee shall exercise the rights and powers vested in it by this Indenture
and use the same degree of care and skill in its exercise as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs.

         (b)      Except during the continuance of an Event of Default:

                  (1)      the Trustee need perform only those duties that are
                           specifically set forth in this Indenture and no
                           others; and

                  (2)      in the absence of bad faith on its part, the Trustee

                           expressed therein, upon certificates or opinions
                           furnished to the Trustee and conforming to the
                           requirements of this Indenture, but in case of any
                           such certificates or opinions which by any provision
                           hereof are specifically required to be furnished to
                           the Trustee, the Trustee shall examine the

                           they conform to the requirements of this Indenture,
                           but need not confirm or investigate the accuracy of

                  (1)      this paragraph (c) does not limit the effect of

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

                  (3)      the Trustee shall not be liable with respect to any
                           action it takes or omits to take in good faith in
                           accordance with a direction received by it pursuant
                           to Section 6.5.

Subparagraphs (c)(1), (2) and (3) shall be in lieu of Sections 315(d)(1),
315(d)(2) and 315(d)(3) of the TIA and such Sections 315(d)(1), 315(d)(2) and
315(d)(3) are hereby expressly excluded from this Indenture, as permitted by the
TIA.

         (d)      Every provision of this Indenture that in any way relates

liability unless it receives indemnity reasonably satisfactory to it against
any loss, liability or expense.

         (f)      Money held by the Trustee in trust hereunder need not be

knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the Corporate Trust Office of the Trustee,
and such notice references the Securities and this Indenture;

         (j)      the rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and to each agent, custodian and other person
employed to act hereunder; and

         (k)      the Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign
an Officers' Certificate, including any person specified as so authorized
in any such certificate previously delivered and not superseded.

         Section 7.3 Individual Rights of Trustee. The Trustee in its individual
or any other capacity may become the owner or pledgee of Securities and may
otherwise deal with the Company or its Affiliates with the same rights it would
have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent or
co-registrar may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11.

         Section 7.4 Trustee's Disclaimer. The Trustee makes no representation
as to the validity or adequacy of this Indenture or the Securities, it shall not
be accountable for the Company's use or application of the proceeds from the
Securities, it shall not be responsible for any statement in the registration
statement for the Securities under the Securities Act or in any offering
document for the Securities, the Indenture or the Securities (other than its
certificate of authentication), or the determination as to which beneficial
owners are entitled to receive any notices hereunder.

         Section 7.5 Notice of Defaults. If a Default occurs and if it is known
to the Trustee, the Trustee shall give to each Securityholder notice of the
Default within 90 days after the occurrence of such Default, or if later, within
30 days after it is known to the Trustee, unless such Default shall have been
cured or waived before the giving of such notice. Notwithstanding the preceding
sentence, except in the case of a Default described in Section 6.1(1) or (2),
the Trustee may withhold the notice if and so long as a committee of its
Responsible Officers in good faith determines that withholding the notice is in
the interests of Securityholders. The second sentence of this Section 7.5 shall
be in lieu of the proviso to Section 315(b) of the TIA and such proviso is
hereby expressly excluded from this Indenture, as permitted by the TIA.

                                       41
<PAGE>
The trustee shall not be deemed to have knowledge of a Default unless a
Responsible Officer of the Trustee has received written notice of such Default.

         Section 7.6 Reports by Trustee to Holders. Within 60 days after each
May 15 beginning with May 15, 2003, the Trustee shall mail to each
Securityholder a brief report dated as of such reporting date that complies with
TIA Section 313(a), if required by such Section 313(a). The Trustee also shall
comply with TIA Section 313(b).

         A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and each securities exchange, if any, on which the
Securities are listed. The Company agrees to notify the Trustee promptly
whenever the Securities become listed on any securities exchange and of any
delisting thereof.

         Section 7.7 Compensation and Indemnity. The Company agrees:

         (a)      to pay to the Trustee from time to time such compensation as
the Company and the Trustee shall from time to time agree in writing for all
services rendered by it hereunder (which compensation shall not be limited
(to the extent permitted by law) by any provision of law in regard to the
compensation of a trustee of an express trust);

         (b)      to reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in
accordance with any provision of this Indenture (including the reasonable
compensation, expenses, advances and disbursements of its agents and counsel),
except any such expense, disbursement or advance as may be caused by its
negligence, bad faith, willful misconduct or recklessness; and

         (c)      to indemnify the Trustee or any predecessor Trustee and their
agents for, and to hold them harmless against, any loss, damage, claim,
liability, cost or expense (including reasonable attorney's fees and expenses,
and taxes (other than taxes based upon, measured by or determined by the income
of the Trustee)) incurred without negligence, bad faith, willful misconduct or
recklessness on its part, arising out of or in connection with the acceptance or
administration of this trust, including the costs and expenses of defending
itself against any claim (whether asserted by the Company or any Holder or any
other person) or liability in connection with the exercise or performance of any
of its powers or duties hereunder.

         The Trustee shall notify the Company promptly of any claim for which it
may seek indemnity; provided that failure to so notify the Company shall not
relieve the Company of its obligations hereunder unless the Company is
materially prejudiced thereby. The Company may elect to defend any such claim
and the Trustee shall cooperate in such defense, in which case, after notice of
such election to defend such claim, the Company shall not be liable to the
Trustee for any legal or other expenses subsequently incurred by the Trustee in
connection with the defense of such claim, unless the Trustee reasonably
determines that representation of the Trustee and the Company by the same
counsel would present a conflict of interest. The Company need not pay for any
settlement made without its consent, which consent shall not be unreasonably
withheld. To secure the Company's payment obligations in this Section 7.7, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the

                                         42
<PAGE>
Trustee, except that held in trust to pay the principal
amount, plus accrued and unpaid interest on particular Securities.

         The Company's payment obligations pursuant to this Section 7.7 shall
survive the discharge of this Indenture and the resignation or removal of the
Trustee. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.1(4) or (5), the expenses including the reasonable
charges and expenses of its counsel, are intended to constitute expenses of
administration under any bankruptcy law.

         Section 7.8 Replacement of Trustee. The Trustee may resign by so
notifying the Company; provided, however, no such resignation shall be effective
until a successor Trustee has accepted its appointment pursuant to this Section
7.8. The Holders of a majority in aggregate principal amount of the Securities
at the time outstanding may remove the Trustee by so notifying the Trustee and
the Company. The Company shall remove the Trustee if:

                  (1)      the Trustee fails to comply with Section 7.10;

                  (2)      the Trustee is adjudged bankrupt or insolvent;

                  (3)      a receiver or public officer takes charge of the
         Trustee or its property; or

                  (4)      the Trustee otherwise becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint, by
resolution of its Board of Directors, a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company satisfactory in form and
substance to the retiring Trustee and the Company. Thereupon the resignation or
removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to
Securityholders. The retiring Trustee shall promptly transfer all property held
by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.7.

         If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of a majority in aggregate principal amount of the Securities at the
time outstanding may petition any court of competent jurisdiction at the expense
of the Company for the appointment of a successor Trustee.

         If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

         Section 7.9 Successor Trustee by Merger. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another

                                          43
<PAGE>
corporation, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

         Section 7.10 Eligibility; Disqualification. The Trustee shall at all
times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). No obligor
on the Securities or person directly or indirectly controlling, controlled by or
under common control with such obligor shall serve as Trustee. The Trustee (or
its parent holding company) shall have a combined capital and surplus of at
least $50,000,000 as set forth in its most recent published annual report of
condition. Nothing herein contained shall prevent the Trustee from filing with
the Commission the application referred to in the penultimate paragraph of TIA
Section 310(b).

         Section 7.11 Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

                                  ARTICLE VIII.
                    SATISFACTION AND DISCHARGE OF INDENTURE;
                   DEPOSITED MONEYS AND GOVERNMENT OBLIGATIONS

         Section 8.1 Satisfaction and Discharge of Indenture. This Indenture
shall cease to be of further effect with respect to the Securities, and the
Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture, when:

         (a)      all Securities theretofore authenticated and delivered
(other than (i) Securities which have been destroyed, lost or stolen and which
have been replaced or paid as provided in Section 2.7 and (ii) Securities for
whose payment money has theretofore been deposited in trust or segregated and
held in trust by the Company and thereafter repaid to the Company or discharged
from such trust, as provided in Section 2.4) have been delivered to the Trustee
for cancellation;

         (b)      the Company has paid or caused to be paid all other sums
payable hereunder by the Company with respect to such Securities; and

         (c)      the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that the conditions
precedent herein provided for relating to the satisfaction and discharge of
this Indenture have been complied with.

         In addition, the Company may terminate all of its obligations under
this Indenture (except the Company's obligations under Sections 7.7 and 8.3)
if:

                  (1)      the Securities mature within one year or all of
         them are to be called for redemption within one year under
         arrangements satisfactory to the Trustee for giving the notice of
         redemption; and

                  (2)      the Company irrevocably deposits in trust with the
         Trustee money or U.S. Government Obligations or a combination thereof
         sufficient to pay principal and interest

                                       44
<PAGE>
         on the Securities to maturity or redemption, as the case may be,
         and to pay all other sums payable by it hereunder. The Company may make
         the deposit only during the one-year period and only if Article 11
         permits it.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 7.7 shall survive such
satisfaction and discharge.

         After a deposit made pursuant to this Section 8.1, the Trustee upon
request shall acknowledge in writing the discharge of the Company's obligations
under this Indenture except for those surviving obligations specified above.

         "U.S. Government Obligations" means securities that are (i) direct
obligations of the United States of America for the payment of which its full
faith and credit is pledged or (ii) obligations of a person controlled or
supervised by and acting as an agency or instrumentality of the United States
of America the payment of which is unconditionally guaranteed as a full faith
and credit obligation by the United States of America, which, in either case,
are not callable or redeemable at the option of the issuer thereof, and shall
also include a depository receipt issued by a bank or trust company as custodian
with respect to any such U.S. Government Obligation or a specific payment of
interest on or principal of any such U.S. Government Obligation held by such
custodian for the account of the holder of a depository receipt; provided that
(except as required by law) such custodian is not authorized to make any
deduction from the amount payable to the holder of such depository receipt from
any amount received by the custodian in respect of the U.S. Government
Obligation or the specific payment of interest on or principal of the U.S.
Government Obligation evidenced by such depository receipt.

         Section 8.2 Application of Trust Moneys. Subject to the provisions of
Section 2.4, all money or U.S. Government Obligations deposited with the Trustee
pursuant to Sections 8.1 shall be held in trust and applied by it, in accordance
with the provisions of the Securities, this Indenture and, in the case of
Section 8.1, such irrevocable trust agreement, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the persons entitled thereto, of the
principal, premium, if any, and interest for whose payment such money has been
deposited with the Trustee. The money or U.S. Government Obligations so held in
trust under Section 8.1 shall not be part of the trust estate under this
Indenture but shall constitute a separate trust fund for the benefit of all
Holders of Securities entitled thereto.

         Section 8.3 Repayment to Company. Upon termination of the trust
established pursuant to Section 8.1, the Trustee and the Paying Agent shall
promptly pay to the Company upon request any excess money held by them. The
Trustee and the Paying Agent shall pay to the Company upon request and, if
applicable, in accordance with the irrevocable trust established pursuant to
Section 8.1 any money or U.S. Government Obligations held by them for the
payment of principal of, premium, if any, or interest on any Securities that
remains unclaimed for two years; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper of general
circulation in the Borough of Manhattan, the City and State of New York, or mail
to the Holder of any such Security, or both, notice that such money remains
unclaimed and that, after a date specified therein, which date shall not be less
than thirty days from the date

                                       45
<PAGE>
of such publication or mailing, any unclaimed balance of such money then
remaining will be repaid to the Company. After payment to the Company,
Securityholders entitled to such payment of principal, premium, if any, and
interest must look to the Company for payment as general creditors unless an
applicable abandoned property law designates another person.

         Section 8.4 Reinstatement. If the Trustee or any Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with Section 8.4
by reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, or by reason of U.S. Government Obligations not paying
principal and interest in such amounts and at such times as are sufficient to
pay the principal of, premium, if any, and interest on the Securities in
accordance with the terms of this Indenture, the Company's obligations under
this Indenture with respect to such Securities shall be revived and reinstated
as though no deposit had occurred pursuant to Section 8.1 until such time as the
Trustee or any Paying Agent is permitted to apply all such money or
U.S. Government Obligations in accordance with Section 8.4; provided, however,
that if the Company has made any payment of interest on, or principal of, such
Securities because of the reinstatement of its obligations hereunder, the
Company shall be subrogated to the rights of the Holders of Securities to
receive such payment from the money or U.S. Government Obligations held by the
Trustee or such Paying Agent for such purpose.

                                   ARTICLE IX.

                                   AMENDMENTS

         Section 9.1 Without Consent of Holders. The Company and the Trustee may
amend or supplement this Indenture or the Securities without the consent of any
Securityholder:

         (a)      to cure any ambiguity, omission, defect or inconsistency
provided that such modification or amendment does not adversely affect the
interests of the holders of the Securities in any material respect;

         (b)      to modify the restrictions on, and procedures for, resale and
other transfers of Securities pursuant to any change in applicable law or
regulation (or the interpretation thereof) or in practice relating to the resale

         (g)      to make any change necessary for the registration of the
Securities under the Securities Act or to comply with the TIA, or any amendment
thereto, or to comply with any requirement of the SEC in connection with the
qualification of the Indenture under the TIA;

                                       46

         (k)      to add or modify other provisions herein with respect to

necessary or desirable and that will not materially adversely affect the
interests of the Holders.

         Section 9.2 With Consent of Holders. With the written consent
(including consent obtained in connection with a tender offer or exchange offer
for the Securities) of the Holders of at least a majority in aggregate principal
amount of the Securities at the time outstanding, the Company and the Trustee
may amend or supplement this Indenture or the Securities. However, without the
consent of each Securityholder affected, an amendment or supplement to this
Indenture or the Securities may not:

         (1)      extend the Stated Maturity date of any of the Security;

         (2)      reduce the interest rate or extend the time for payment of
 interest thereon;

         (3)      reduce the principal amount of or premium of any Security;

         (5)      adversely change the Company's obligation to redeem any
 Security upon a Fundamental Change;

         (6)      make any change that impairs the right of a Securityholder
to institute suit for the enforcement of any payment on any Security;

         (7)      change the currency in which any Security is payable other
 than as stated in the Security;

         (8)      make any change that impairs the right of a Securityholder

materially adverse to the Holders, the provisions of Article XI

         (11)     change any obligation of the Company to maintain an office or

<PAGE>
         (12)     subject to specified exceptions, modify certain of the
provisions set forth in Sections 9.1 and 9.2 hereof relating to
modification or waiver of provisions set forth in this Indenture; or

         (13)     reduce the percentage of Securities required for consent
 to any modification of this Indenture.

         It shall not be necessary for the consent of the Holders under this
Section 9.2 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof.

         After an amendment under this Section 9.2 becomes effective, the
Company shall mail to each Holder a notice briefly describing the amendment.

         Section 9.3 Compliance with Trust Indenture Act. Every amendment or
supplemental indenture executed pursuant to this Article shall comply with the
TIA.

         Section 9.4 Revocation and Effect of Consents, Waivers and Actions.
Until an amendment, waiver or other action by Holders becomes effective, a
consent thereto by a Holder of a Security hereunder is a continuing consent by
the Holder and every subsequent Holder of that Security or portion of the
Security that evidences the same obligation as the consenting Holder's Security,
even if notation of the consent, waiver or action is not made on the Security.
However, any such Holder or subsequent Holder may revoke the consent, waiver or
action as to such Holder's Security or portion of the Security if the Trustee
receives the notice of revocation before the date the amendment, waiver or
action becomes effective. After an amendment, waiver or action becomes
effective, it shall bind every Securityholder.

         Section 9.5 Notation on or Exchange of Securities. Securities
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article IX 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 determine, new Securities so
modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any such supplemental indenture may be prepared and executed by
the Company and authenticated and delivered by the Trustee in exchange for
outstanding Securities.

         Section 9.6 Trustee To Sign Supplemental Indentures. The Trustee shall
sign any supplemental indenture authorized pursuant to this Article IX if the
amendment contained therein does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may, but need
not, sign such supplemental indenture. In signing such supplemental indenture
the Trustee shall receive, and (subject to the provisions of Section 7.1) 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.

         Section 9.7 Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture under this Article, this Indenture shall be modified

this Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby.

                                   ARTICLE X.

                                   CONVERSIONS

         Section 10.1 Conversion Privilege. Subject to and upon compliance with
the provisions of this Indenture, a Holder of a Security may convert such
Security into shares of Common Stock at any time during the period stated in
Paragraph 8 of the Securities. Neither the Conversion Agent nor the Company
shall have any obligation to determine the Trading Price for purposes of
determining whether the Securities are convertible pursuant to Paragraph 8(c) of
the Securities, unless a Holder sends to the Company a written notice requesting
such determination and provides reasonable evidence that the conditions to a
conversion under Paragraph 8(c) of the Securities have been met. Upon receipt of
such notice, together with such reasonable evidence, the Company shall instruct
the Conversion Agent to determine the Trading Price beginning with the first
trading day after receipt of such notice and ending on the first trading day
when the condition to conversion under Paragraph 8(c) is no longer met.

         The rate at which Common Stock shall be delivered upon conversion
(herein called the "Conversion Rate") shall be initially 23.8095 shares of
Common Stock for each U.S. $1,000 principal amount of Securities. The Conversion
Rate shall be adjusted in certain instances as provided in this Article X. The
price at which Common Stock shall be delivered upon conversion (herein called
the "Conversion Price") shall at any time be equal to U.S. $1,000 divided by the
then applicable Conversion Rate (and rounded to the nearest cent).

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

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

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

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

                  (iii)    the period, if any, (x) commencing on the date next
         succeeding the Ex-Dividend Time with respect to the next preceding (a)
         issuance of rights, warrants or options or (b) distribution, in each
         case, for which an adjustment is required by the provisions of Section
         10.7, 10.8 or 10.9 and (y) proceeding through the last full trading day
         prior to the Time of Determination with respect to the rights, warrants
         or options or

                                       49
<PAGE>
         distribution in respect of which the Average Sale Price is being
         calculated (excluding days within such period, if any, which are not
         trading days).

         In the event that the Ex-Dividend Time (or in the case of a
subdivision, combination or reclassification, the effective date with respect
thereto) with respect to a dividend, subdivision, combination or
reclassification to which Section 10.6(1), (2),(3) or (4) applies occurs during
the period applicable for calculating "Average Sale Price" pursuant to the
definition in the preceding sentence, "Average Sale Price" shall be calculated
for such period in a manner determined by the Board of Directors to reflect the
impact of such dividend, subdivision, combination or reclassification on the
Sale Price of the shares of Common Stock during such period.

         "Time of Determination" means the time and date of the earlier of (i)
the determination of stockholders entitled to receive rights, warrants or
options or a distribution, in each case, to which Section 10.7, 10.8 or 10.9
applies and (ii) the time ("Ex-Dividend Time") immediately prior to the
commencement of "ex-dividend" trading for such rights, warrants or options or
distribution on Nasdaq or such other U.S. national or regional exchange or
market on which the shares of Common Stock are then listed or quoted.

         For purposes of this Article X, "fair market value" means the fair
market value, as determined in good faith by the Board of Directors (except as
Section 10.8 otherwise provides in the case of a Spin-off) and set forth in a
certified resolution filed with the Trustee.

         Section 10.2 Conversion Procedure. To convert a Security, a Holder must
satisfy the requirements in Paragraph 8 of the Securities. The first Business
Day on which the Holder satisfies all those requirements and submits such
Holder's Securities for conversion is the conversion date (the "Conversion
Date").

         As soon as practicable after the Conversion Date, the Company shall
deliver to the Holder, through the Conversion Agent, a certificate for, or a
beneficial interest in a global certificate representing, the number of full
shares of Common Stock issuable upon the conversion or exchange and cash in lieu
of any fractional share determined pursuant to Section 10.3. The person in whose
name the certificate is registered shall be treated as a shareholder of record
as of the close of business on the Conversion Date. Upon conversion by a Holder
of a Security in its entirety, such person shall no longer be a Holder of such
Security.

         No payment or adjustment will be made for dividends on, or other
distributions with respect to, any shares of Common Stock except as provided in
this Article X. On conversion of a Security, except as provided below with
respect to interest payable on Securities or portions thereof converted after a
Regular Record Date, that portion of accrued and unpaid interest on the
converted Securities attributable to the period from the most recent Interest
Payment Date through the Conversion Date shall not be cancelled, extinguished or
forfeited, but rather shall be deemed to be paid in full to the Holder thereof
through delivery of the shares of Common Stock (together with the cash payment,
if any, in lieu of fractional shares) for the Security being converted pursuant
to the provisions hereof. The Company will not adjust the Conversion Rate to
account for accrued interest, if any. If the Holder converts more than one
Security at the same time, the number of shares of Common Stock issuable upon
the conversion shall be based on the total principal amount of the Securities
converted.

                                       50
<PAGE>
         The Securities or portions thereof surrendered for conversion during
the period from the close of business on any Regular Record Date to the opening
of business on the date on which such interest is payable shall be accompanied
by payment to the Company or its order, in New York Clearing House funds or
other funds acceptable to the Company, of an amount equal to the interest
payable on such interest payment date on the principal amount of the Securities
or portions thereof being surrendered for conversion; provided that interest
shall not be payable upon the interest payment date if (i) the Security has been
called for redemption on a Redemption Date that occurs during this period or
(ii) the Security is to be redeemed in connection with a Fundamental Change on a
Redemption Date that occurs during this period.

         If the last day on which a Security may be converted is a Legal
Holiday, the Security may be surrendered on the next succeeding day that is not
a Legal Holiday.

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

         Section 10.3 Fractional Shares. The Company will not issue fractional
shares of Common Stock upon conversion of a Security. Instead, the Company will
pay cash based on the current market value for all fractional shares. The
current market value of a fractional share shall be determined, to the nearest
1/1,000th of a share, by multiplying the Sale Price on the last trading day
immediately prior to the Conversion Date, of a full share by the fractional
amount and rounding the product to the nearest whole cent. It is understood that
if a Holder elects to have more than one Security converted, the number of
shares of Common Stock shall be based on the aggregate principal amount of
Securities to be converted.

         Section 10.4 Taxes on Conversion. If a Holder submits a Security for
conversion, the Company shall pay all documentary, transfer or stamp taxes or
duties and all other taxes or duties, if any, which may be imposed by the United
States or any political subdivision thereof or taxing authority thereof or
therein with respect to the issuance of shares of Common Stock upon the
conversion. However, the Holder shall pay any such tax which is due because the
Holder requests the shares to be issued in a name other than the Holder's name.
The Conversion Agent may refuse to deliver the certificates representing the
shares of Common Stock being issued in a name other than the Holder's name until
the Conversion Agent receives a sum sufficient to pay any tax which will be due
because the shares are to be issued in a name other than the Holder's name.

         Nothing herein shall preclude any tax withholding required by law or
regulations.

         Section 10.5 Company To Provide Stock. The Company shall, prior to
issuance of any Securities under this Article X, and from time to time as may be
necessary, reserve out of its authorized but unissued shares of Common Stock a
sufficient number of shares of Common Stock to permit the conversion of the
Securities in full.

         All shares of Common Stock delivered upon conversion of the Securities
shall be newly issued shares or treasury shares, shall be duly and validly
issued and fully paid and nonassessable, and shall be free from preemptive
rights and free of any lien or adverse claim.

                                       51
<PAGE>
The Company will endeavor promptly to comply with all federal and state
securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of Securities, if any, and will list or cause to have quoted such
shares of Common Stock on each national securities exchange on which the shares
of Common Stock are then listed or quoted.

         Section 10.6 Adjustment for Change in Capital Stock. If the Company:

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

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

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

         (4)      issues by reclassification of its Common Stock any shares of
Capital Stock (other than Capital Stock adjustments requiring an adjustment
pursuant to Sections 10.7 and 10.8);

then the conversion privilege and the Conversion Rate in effect immediately
prior to such action shall be adjusted so that the Holder of a Security
thereafter converted may receive the number of shares of Capital Stock of the
Company which such Holder would have owned immediately following such action if
such Holder had converted the Security immediately prior to the record date for
such action.

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

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

         Section 10.7 Adjustment for Rights Issue. If the Company distributes
any rights or warrants to all or substantially all holders of shares of its
Common Stock entitling them (for a period within 45 days after such
distribution) to purchase shares of Common Stock at a price per share less than
the Average Sale Price as of the Time of Determination (except that no
adjustment will be made if the Holders of Securities may participate in the
distribution without conversion on a basis and with the notice that the Board of
Directors determines to be fair and appropriate in light of the basis and notice
on which holders of shares of Common Stock participate in the distribution), the
Conversion Rate shall be adjusted in accordance with the formula:

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

                                          52
<PAGE>
         where:

         R'   =   the adjusted Conversion Rate.

         R    =   the current Conversion Rate.

         O    =   the number of shares of Common Stock outstanding on
                  the record date for the distribution to which this
                  Section 10.7 is being applied.

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

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

         M    =   the Average Sale Price, minus, in the case of (i) a
                  distribution to which Section 10.6(4) applies or (ii) a
                  distribution to which Section 10.8 or 10.9 applies, for which,
                  in each case, (x) the record date shall occur on or before
                  the record date for the distribution to which this
                  Section 10.7 applies and (y) the Ex-Dividend Time shall occur
                  on or after the date of the Time of Determination for the
                  distribution to which this Section 10.7 applies, the fair
                  market value (on the record date for the distribution to which
                  this Section 10.7 applies) of the:

                           (1)      Capital Stock of the Company
                  distributed in respect of each share of Common Stock in such
                  Section 10.6(4) distribution; and

                           (2)      the Company's debt, securities or assets or
                  certain rights, warrants or options to purchase securities of
                  the Company distributed in respect of each share of Common
                  Stock in such Section 10.8 or 10.9 distribution.

         The adjustment shall become effective immediately after the record date
for the determination of shareholders entitled to receive the rights, warrants
or options to which this Section 10.7 applies. To the extent the shares of
Common Stock subject to such rights, warrants or options have not been issued
when such rights, warrants or options expire, then the Conversion Rate shall
promptly be readjusted to the Conversion Rate which would then be in effect had
the adjustment upon the issuance of such rights, warrants or options been made
on the basis of the actual number of shares of Common Stock issued upon the
exercise of such rights, warrants or options.

         No adjustment shall be made under this Section 10.7 if the application
of the formula stated above in this Section 10.7 would result in a value of R'
that is equal to or less than the value of R.

         Section 10.8 Adjustment for Certain Distributions. If the Company
distributes to all holders of its shares of Common Stock any of its debt,
securities or assets or any rights, warrants or options to purchase securities
of the Company (including securities or cash, but excluding (x) distributions of
Capital Stock referred to in Section 10.6, distributions of rights, warrants or

                                       53
<PAGE>
options referred to in Section 10.7 and distributions exclusively in cash
pursuant to Section 10.9, (y) payments made to redeem rights issued under any
present or future rights agreement or plan of the Company (except that no
adjustment will be made if the Holders of Securities may participate in the
distribution without conversion on a basis and with notice that the Board of
Directors determines to be fair and appropriate in light of the basis and notice
on which holders of the Common Stock participate in the distribution), the
Conversion Rate shall be adjusted, subject to the provisions of the last
paragraph of this Section 10.8, in accordance with the formula:

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

         where:

         R'  =   the adjusted Conversion Rate.

         R   =   the current Conversion Rate.

         M   =   the Average Sale Price, minus, in the case of (i) a
                 distribution to which Section 10.6(4) applies or (ii) a
                 distribution to which Section 10.7 or 10.9 applies, for which,
                 in each case, (x) the record date shall occur on or before the
                 record date for the distribution to which this Section 10.8
                 applies and (y) the Ex-Dividend Time shall occur on or after
                 the date of the Time of Determination for the distribution to
                 which this Section 10.8 applies, the fair market value (on the
                 record date for the distribution to which this Section 10.8
                 applies) of the:

                           (1)      Capital Stock of the Company distributed in
                  respect of each share of Common Stock in such Section
                  10.6(4) distribution; and

                           (2)      the Company's debt, securities or assets or
                  certain rights, warrants or options to purchase securities of
                  the Company distributed in respect of each share of Common
                  Stock in such Section 10.7 or 10.9 distribution.

         F   =   the fair market value (on the record date for the
                 distribution to which this Section 10.8 applies) of the
                 assets, securities, rights, warrants or options to be
                 distributed in respect of each share of Common Stock in the
                 distribution to which this Section 10.8 is being applied
                 (including, in the case of cash dividends or other cash
                 distributions giving rise to an adjustment, all such cash
                 distributed concurrently).

         In the event the Company distributes shares of Capital Stock of a
Subsidiary, the Conversion Rate will be adjusted, if at all, based on the fair
market value of the Subsidiary stock so distributed relative to the market value
of the Common Stock, as discussed below. The Board of Directors of the Company
shall determine fair market values for the purposes of this Section 10.8, except
that in respect of a dividend or other distribution of shares of publicly traded
Capital Stock of any class or series, or similar equity interests, of or
relating to a Subsidiary or other business unit of the Company (a "Spin-off"),
the fair market value of the securities to be

                                       54
<PAGE>
distributed shall equal the average of the daily Sales Prices of those
securities for the five consecutive trading days commencing on and including the
sixth day of trading of those securities after the effectiveness of the Spin-off
and the average of the Sales Prices shall mean the average Sales Prices for the
Common Stock for the same five trading days. In the event, however, that an
underwritten initial public offering of the securities in the Spin-off occurs
simultaneously with the Spin-off, fair market value of the securities
distributed in the Spin-off shall mean the initial public offering price of such
securities and the Average Sale Price shall mean the Sales Price for the Common
Stock on the same trading day.

         The adjustment shall become effective immediately after the record date
for the determination of shareholders entitled to receive the distribution to
which this Section 10.8 applies, except that an adjustment related to a Spin-off
shall become effective at the earlier to occur of (i) 10 trading days after the
effective date of the Spin-off and (ii) the initial public offering of the
securities distributed in the Spin-off.

         In the event that, with respect to any distribution to which this
Section 10.8 would otherwise apply, the difference "M-F" as defined in the above
formula is less than $1.00 or "F" is equal to or greater than "M," then the
adjustment provided by this Section 10.8 shall not be made and in lieu thereof
the provisions of Section 10.16 shall apply to such distribution.

         Section 10.9 Adjustment for All-Cash Distribution. If the Company shall
pay or make a dividend or other distribution consisting exclusively of cash to
all holders of its Common Stock (excluding any cash that is distributed (x)
upon a merger or consolidation to which Section 10.16 applies or (y) as part of
a distribution referred to in Section 10.8), in an aggregate amount (A) by
which a quarterly cash dividend declared by the Board and paid during any
fiscal quarter on a per share basis exceeds the greater of (i) the amount so
distributed during the fiscal quarter immediately preceding such fiscal quarter
and (ii) 2.5% of the average of the Sale Prices of the Common Stock during the
10 trading days immediately prior to the declaration of the dividend or other
distribution or (B) of any special cash dividend or other all-cash distribution
that is not a quarterly dividend covered by clause (A) above the Conversion
Rate shall be adjusted, subject to the last paragraph of this Section 10.9, in
accordance with the following formula:

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

         where:

         R'  =   the adjusted Conversion Rate.

         R   =   the current Conversion Rate.

         M   =   the Average Sale Price, minus, in the case of (i) a
                 distribution to which Section 10.6(4) applies or (ii) a
                 distribution to which Section 10.7 or 10.8 applies, for which,
                 in each case, (x) the record date shall occur on or before the
                 record date for the distribution to which this Section 10.9
                 applies and (y) the Ex-Dividend Time shall occur on or after
                 the date of the Time of Determination for the

                                       55
<PAGE>
                  distribution to which this Section 10.9 applies, the fair
                  market value (on the record date for the distribution to
                  which this Section 10.9 applies) of the:

                           (1)      Capital Stock of the Company distributed
                  in respect of each share of Common Stock in such Section
                  10.6(4) distribution; and

                           (2)      the Company's debt, securities or assets or
                  certain rights, warrants or options to purchase securities of
                  the Company distributed in respect of each share of Common
                  Stock in such Section 10.7 or 10.8 distribution.

         C   =    (1) the amount by which a quarterly cash dividend exceeds
                  the threshold specified in clause (A), or (2) the amount of
                  any distribution per share as contemplated by clause (B), as
                  applicable.

         The adjustment shall become effective immediately prior to the opening
of business on the day following the date fixed for payment of such
distribution.

         In the event that, with respect to any distribution to which this
Section 10.9 would otherwise apply, the difference "M-C" as defined in the above
formula is less than $1.00 or "C" is equal to or greater than "M," then the
adjustment provided by this Section 10.9 shall not be made and in lieu thereof
the provisions of Section 10.16 shall apply to such distribution. Any adjustment
pursuant to this Section made as a result of a distribution described in Section
10.9 above shall be made only to the extent that the amount distributed exceeds
the amount so distributed during the fiscal quarter immediately preceding the
date of issuance of the Securities.

         Section 10.10 Adjustment for Tender Offers. If (a) the Company or any
Subsidiary of the Company acquires shares of the Company's Common Stock by way
of a tender or exchange offer, other than an odd-lot offer by the Company or any
of its Subsidiaries, for the Common Stock (excluding stock options) to the
extent that the offer involves consideration per share of Common Stock that,
exceeds the Sale Price of a share of Common Stock on the trading day next
succeeding the Expiration Time; or (b) a person other than the Company or any
Subsidiary, in respect of a tender or exchange offer that increases the
offeror's beneficial ownership (as used in Section 13(d) of the Exchange Act) of
Common Stock to more than twenty-five percent (25%) of the total shares of
Common Stock outstanding, makes a payment of consideration per share of Common
Stock that exceeds the Sale Price of a share of Common Stock on the trading day
next succeeding the Expiration Time, and as of the Expiration Time, the Board of
Directors is not recommending rejection of the offer, in each case the
Conversion Rate shall be adjusted in accordance with the formula:

                                      F + (N x M)
                           R' = R x  -------------
                                        (O x M)
         where:

         R'  =   the adjusted Conversion Rate.

         R   =   the current Conversion Rate.

                                       56
<PAGE>
         O   =    the number of shares of Common Stock outstanding (including
                  any tendered or exchanged shares) at the last time tenders of
                  exchanges may be made pursuant to such tender or exchange
                  offer (the "Expiration Time").

         M   =    the Sale Price per share of Common Stock on the trading day
                  on the NYSE next succeeding the Expiration Time.

         F   =    the sum of the fair market value of the aggregate
                  consideration payable to stockholders based on the acceptance
                  (up to any maximum specified in the terms of the tender or
                  exchange offer) of all shares of Common Stock validly tendered
                  or exchanged and not withdrawn as of the Expiration Time (the
                  shares deemed so accepted, up to any such maximum, being
                  referred to as the "Purchased Shares").

         N   =    the number of shares of Common Stock (less any Purchased
                  Shares) at the Expiration Time.

         The adjustment shall become effective immediately prior to the opening
of business on the day following the Expiration Time.

         If the person is obligated to purchase shares pursuant to any such
tender or exchange offer, but such person is permanently prevented by applicable
law from effecting any such purchases or all such purchases are rescinded, the
Conversion Rate shall again be adjusted to be the Conversion Rate that would
then be in effect if such tender or exchange offer had not been made.
Notwithstanding the foregoing, the adjustment described in this Section 10.10(b)
shall not be made if, as of the Expiration Time, the offering documents with
respect to such offer disclose a plan or intention to cause the Company to
engage in any transaction described in Article V.

         Section 10.11 When Adjustment May Be Deferred. No adjustment in the
Conversion Rate need be made unless the adjustment would require an increase or
decrease of at least 1% in the Conversion Rate. Any adjustments that are not
made shall be carried forward and taken into account in any subsequent
adjustment.

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

         Section 10.12 When No Adjustment Required. Notwithstanding any
provision to the contrary herein, no adjustment to the Conversion Rate need be
made as a result of:

         (1)      (i) the issuance of the rights; (ii) the distribution of
separate certificates representing the rights; (iii) the exercise or
redemption of the rights in accordance with any rights agreement;
or (iv) the termination or invalidation of the rights, in each case,
pursuant to the Company's existing stockholders rights plan, as amended,
modified, or supplemented from time to
time or any newly adopted stockholders rights plans;

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

                                       57
<PAGE>
         (3)      upon the issuance of any shares of Common Stock or options or
rights to purchase those shares pursuant to any present or future employee,
director or consultant benefit plan or program of or assumed by the Company or
any of its Subsidiaries; or

         (4)      upon the issuance of any shares of Common Stock pursuant to
any option, warrant, right, or exercisable, exchangeable or convertible security
outstanding as of the date the Securities were first issued.

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

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

         Section 10.13 Notice of Adjustment. Whenever the Conversion Rate is
adjusted, the Company shall promptly mail to Holders a notice of the adjustment.
The Company shall file with the Trustee and the Conversion Agent such notice
briefly stating the facts requiring the adjustment and the manner of computing
it. The certificate shall be conclusive evidence that the adjustment is correct.
Neither the Trustee nor any Conversion Agent shall be under any duty or
responsibility with respect to any such certificate except to exhibit the same
to any Holder desiring inspection thereof.

         Section 10.14 Voluntary Increase. The Company from time to time may
increase the Conversion Rate by any amount at any time for at least 20 days, so
long as the increase is irrevocable during such period. In addition, the Company
may increase the Conversion Rate if the Board of Directors deems it advisable to
avoid or diminish any income tax to holders of Common Stock resulting from any
stock or rights distribution. Whenever the Conversion Rate is increased, the
Company shall mail to Securityholders and file with the Trustee and the
Conversion Agent a notice of the increase. The Company shall mail the notice at
least 15 days before the date the increased Conversion Rate takes effect. The
notice shall state the increased Conversion Rate and the period it will be in
effect. A voluntary increase of the Conversion Rate does not change or adjust
the Conversion Rate otherwise in effect for purposes of Section 10.6, 10.7,
10.8, 10.9 or 10.10.

         Section 10.15 Notice of Certain Transactions. If:

         (a)      the Company takes any action that would require an adjustment
in the Conversion Rate pursuant to Section 10.6, 10.7, 10.8, 10.9 or 10.10
(unless no adjustment is to occur pursuant to Section 10.12); or

         (b)      the Company takes any action that would require a supplemental
indenture pursuant to Section 10.16; or

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

then the Company shall mail to Holders and file with the Trustee and the
Conversion Agent a notice stating the proposed record date for a dividend,
distribution or subdivision or the proposed

                                       58
<PAGE>
effective date of a combination, reclassification, consolidation, merger,
binding share exchange, transfer, liquidation or dissolution. The Company shall
file and mail the notice at least 15 days before such date. Failure to file or
mail the notice or any defect in it shall not affect the validity of the
transaction.

         Section 10.16 Reorganization of Company; Special Distributions. If
the Company is a party to a transaction subject to Article V (other than a sale
of all or substantially all of the properties and assets of the Company in a
transaction in which the holders of shares of Common Stock immediately prior to
such transaction do not receive securities, cash or other assets of the Company
or any other person) or a merger or binding share exchange which reclassifies or
changes its outstanding shares of Common Stock, the person obligated to deliver
securities, cash or other assets upon conversion of Securities shall enter into
a supplemental indenture. If the issuer of securities deliverable upon
conversion of Securities is an Affiliate of the successor Company, that issuer
shall join in the supplemental indenture.

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

         If this Section 10.16 applies, neither Section 10.6 nor 10.7 applies.

         If the Company makes a distribution to all holders of its shares of
Common Stock of any of its debt, securities or assets or any rights, warrants or
options to purchase securities of the Company or any cash that, but for the
provisions of the last paragraph of Section 10.8 or 10.9, would otherwise result
in an adjustment in the Conversion Rate pursuant to the provisions of Section
10.8 or 10.9, then, from and after the record date for determining the holders
of shares of Common Stock entitled to receive the distribution, a Holder of a
Security that converts such Security in accordance with the provisions of this
Indenture shall upon such conversion be entitled to receive, in addition to the
shares of shares of Common Stock into which the Security is convertible, the
kind and amount of securities, cash or other assets comprising the distribution
that such Holder would have received if such Holder had converted the Security
immediately prior to the record date for determining the holders of shares of
Common Stock entitled to receive the distribution.

         Section 10.17 Company Determination Final. Any determination that the
Company or the Board of Directors must make pursuant to Section 10.3, 10.6,
10.7, 10.8, 10.9, 10.10, 10.11, 10.12, 10.16 or 10.19 is conclusive, absent
manifest error.

         Section 10.18 Trustee's Adjustment Disclaimer. The Trustee has no duty
to determine when an adjustment under this Article X should be made, how it
should be made or what it

                                       59
<PAGE>
should be. The Trustee has no duty to determine whether a supplemental indenture
under Section 10.16 need be entered into or whether any provisions of any
supplemental indenture are correct. The Trustee shall not be accountable for and
makes no representation as to the validity or value of any securities or assets
issued upon conversion of Securities. The Trustee shall not be responsible for
the Company's failure to comply with this Article X. Each Conversion Agent shall
have the same protection under this Section 10.18 as the Trustee.

         Section 10.19 Simultaneous Adjustments. In the event that this
Article X requires adjustments to the Conversion Rate under more than one of
Sections 10.6(4), 10.7, 10.8 or 10.9, and the record dates for the distributions
giving rise to such adjustments shall occur on the same date, then such
adjustments shall be made by applying, first, the provisions of Section 10.6,
second, the provisions of Section 10.8, third, the provisions of Section 10.7
and, fourth, the provisions of Section 10.9.

         Section 10.20 Successive Adjustments. After an adjustment to the
Conversion Rate under this Article X, any subsequent event requiring an
adjustment under this Article X shall cause an adjustment to the Conversion Rate
as so adjusted.

         Section 10.21 Restriction on Common Stock Issuable upon Conversion.

         (a)      Shares of Common Stock to be issued upon conversion of the
Securities prior to the effectiveness of a Shelf Registration Statement shall be
physically delivered in certificated form or in the form of beneficial interests
in book-entry Common Stock registered in the name of the Depositary or a nominee
thereof to the holders converting such Securities, and the certificate or
certificates representing such shares of Common Stock shall bear the Restricted
Common Stock Legend unless removed in accordance with Section 10.21(c).

         (b)      If (i) shares of Common Stock to be issued upon conversion of
a Security prior to the effectiveness of a Shelf Registration Statement are to
be registered in a name other than that of the holder of such Security or (ii)
shares of Common Stock represented by a certificate bearing the Restricted
Common Stock Legend are transferred subsequently by such holder, then, unless
the Shelf Registration Statement has become effective and such shares are being
transferred pursuant to the Shelf Registration Statement, the holder must
deliver to the transfer agent for the Common Stock a certificate in
substantially the form of Exhibit D as to compliance with the restrictions on
transfer applicable to such shares of Common Stock, and neither the transfer
agent nor the registrar for the Common Stock shall be required to register any
transfer of such Common Stock not so accompanied by a properly completed
certificate.

         (c)      Except for transfers in connection with a Shelf Registration
Statement, if certificates representing shares of Common Stock are issued upon
the registration of transfer, exchange or replacement of any other certificate
representing shares of Common Stock bearing the Restricted Common Stock Legend,
or if a request is made to remove such Restricted Common Stock Legend from
certificates representing shares of Common Stock, the certificates so issued
shall bear the Restricted Common Stock Legend, or the Restricted Common Stock
Legend shall not be removed, as the case may be, unless there is delivered to
the Company such satisfactory evidence, which may include an opinion of counsel
as may be reasonably required by the Company, that neither the legend nor the
restrictions on transfer set forth therein are

                                       60
<PAGE>
required to ensure that transfers thereof comply with the provisions of Rule
144A, Rule 144 or Regulation S under the Securities Act or that such shares of
Common Stock are securities that are not "restricted" within the meaning of Rule
144 under the Securities Act. Upon provision to the Company of such reasonably
satisfactory evidence, the Company shall cause the transfer agent for the Common
Stock to countersign and deliver certificates representing shares of Common
Stock that do not bear the legend.

                                   ARTICLE XI.

                                  SUBORDINATION

         Section 11.1 Securities Subordinate to Senior Debt. The Company
covenants and agrees, and each Holder of a Security by his acceptance thereof
likewise covenants and agrees, that to the extent and in the manner hereinafter
set forth in this Article (subject to the provisions of Article VIII) the
indebtedness represented by the Securities and the payment of the principal
amount, premium, if any, plus accrued and unpaid interest and Liquidated Damages
Amount, if any, on, and any payment of the Purchase Price, the Fundamental
Change Purchase Price or the Redemption Price with respect to, each and all of
the Securities are hereby expressly made subordinate and subject in right of
payment to the prior payment in full of all Senior Debt in cash or other payment
satisfactory to holders of Senior Debt, whether outstanding at the date of this
Indenture or thereafter incurred.

         Section 11.2 No Payments in Certain Circumstances; Payment Over of
Proceeds Upon Dissolution, Etc. No payment on account of the principal amount,
premium, if any, or accrued and unpaid interest and Liquidated Damages Amount,
if any, on, or redemption or repurchase of, the Securities shall be made (other
than payments made from any trust created pursuant to Section 8.1 hereof) if, at
the time of such payment: (a) a default in the payment of principal, premium, if
any, or interest or other amounts due on or in connection with any Designated
Senior Debt, including any default under any redemption or repurchase
obligation, occurs and is continuing (or, in the case of Designated Senior Debt
for which there is a period of grace, in the event of such a default that
continues beyond the period of grace, if any, specified in the instrument or
lease evidencing such Senior Debt), unless and until such default shall have
been cured or waived or shall have ceased to exist (a "payment default"); or (b)
a default, other than a payment default, on Designated Senior Debt occurs and is
continuing that then permits holders of such Designated Senior Debt to
accelerate its maturity, or in the case of a lease, a default occurs and is
continuing that permits the lessor to either terminate the lease or require the
Company to make an irrevocable offer to terminate the lease following an event
of default under the lease, and the Trustee receives a notice of such default (a
"Payment Blockage Notice") from the Company, a holder of Designated Senior Debt
or any other person permitted to give such notice hereunder. Notwithstanding the
foregoing, the Company may make, and the Trustee may receive and shall apply,
any payment in respect of the Securities (for principal amount, premium, if any,
or accrued and unpaid interest and Liquidated Damages Amount, if any, or
repurchase) if such payment was made prior to the occurrence of any of the
contingencies specified in clauses (a) and (b) above.

         If the Trustee receives any Payment Blockage Notice pursuant to clause
(b) above, no subsequent Payment Blockage Notice shall be effective for purposes
of this Section 11.2 unless and until at least 365 days shall have elapsed since
the initial effectiveness of the immediately

                                       61
<PAGE>
prior Payment Blockage Notice. No nonpayment default that existed or was
continuing on the date of delivery of any Payment Blockage Notice to the Trustee
(unless such default was waived, cured or otherwise ceased to exist and
thereafter subsequently reoccurred) shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

         The Company may and shall resume payments on and distributions in
respect of the Securities (including missed payments, if any) upon the earlier
of: (A) the date upon which the default is cured or waived or ceases to exist,
or (B) in the case of a default referred to in clause (b) of the second
preceding paragraph, the earlier of the date on which such nonpayment default is
cured or waived or ceases to exist or 179 days after such Payment Blockage
Notice is received, if the maturity of such Designated Senior Debt has not been
accelerated, or in the case of any lease, 179 days after notice is received if
the Company has not received notice that the lessor under such lease has
exercised its rights to terminate the lease or require the Company to make an
irrevocable offer to terminate the lease following an event of default under
such lease.

         Upon (i) any acceleration of the principal amount due on the Securities
or (ii) any payment or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to creditors upon any
dissolution, winding up or total or partial liquidation or reorganization of the
Company, whether voluntary or involuntary, or in bankruptcy, insolvency,
receivership or other proceedings, all principal amount, premium, if any,
sinking fund and interest or other amounts due, or to become due, upon or in
connection with all Senior Debt shall first be paid in full in cash or other
payment satisfactory to the holders of such Senior Debt, or payment thereof
provided for in cash or other form of acceptable payment in accordance with its
terms, before any payment is made on account of the principal amount, premium,
if any, or accrued and unpaid interest and Liquidated Damages Amount, if any,
on, or repurchase of, the indebtedness evidenced by the Securities, and upon any
such dissolution or winding up or liquidation or reorganization any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the Holders of the Securities or the Trustee
under this Indenture would be entitled, except for the provisions hereof, shall
be paid by the Company or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other person making such payment or distribution, or by the
Holders of the Securities or by the Trustee under this Indenture if received by
them or it, as the case may be, directly to the holders of Senior Debt (pro rata
to each such holder on the basis of the respective amounts of Senior Debt held
by such holder) or their representatives, to the extent necessary to pay all
Senior Debt in full, in cash, or other payment satisfactory to the holders of
such Senior Debt, after giving effect to any concurrent payment or distribution
to or for the holders of Senior Debt, before any payment or distribution is made
to the Holders of the Securities or to the Trustee under this Indenture.

         In the event that, contrary to the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities (other than junior securities, as defined in Section
11.11), shall be received by the Trustee or the Holders of the Securities before
all Senior Debt is paid in full in cash or other payment satisfactory to the
holders of Senior Debt or provision made for such payment in accordance with its
terms, such payment or distribution shall be paid over or delivered to the
holders of such Senior Debt or their representative or representatives, or to
the trustee or trustees under any indenture pursuant to which any instruments
evidencing any of such Senior Debt have been issued, as their respective
interests may appear, for application to the payment of all Senior Debt
remaining unpaid to the

                                       62
<PAGE>
extent necessary to pay all such Senior Debt in full in cash or other payment
satisfactory to the holders of such Senior Debt, in accordance with its terms,
after giving effect to any concurrent payment or distribution to or for the
holders of such Senior Debt.

         Subject to the payment in full in cash of all Senior Debt in cash or
other payment satisfactory to holders of such Senior Debt, the Holders of the
Securities (together with the holders of any other indebtedness of the Company
that is subordinated in right of payment to the payment in full of all Senior
Debt that is not subordinated in right of payment to the Securities and that by
its terms grants such right of subrogation to the holders thereof) shall be
subrogated to the rights of the holders of Senior Debt to receive payments or
distribution of assets of the Company made on the Senior Debt until the
principal of, premium, if any, and interest on, or amounts payable upon
repurchase of, the Securities shall be paid in full; and, for the purposes of
such subrogation, no payments or distributions to the holders of Senior Debt of
any cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article, and no
payment over pursuant to the provisions of this Article to the holders of Senior
Debt by the Holders of the Securities or the Trustee, shall, as between the
Company, its creditors other than the holders of Senior Debt, and the Holders of
Securities, be deemed to be a payment by the Company to the holders of or on
account of Senior Debt, it being understood that the provisions of this Article
are and are intended solely for the purpose of defining the relative rights of
the Holders of the Securities, on the one hand, and the holders of Senior Debt,
on the other hand.

         Section 11.3 Trustee to Effectuate Subordination. Each Holder of a
Security by his acceptance thereof authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes.

         Section 11.4 No Waiver of Subordination Provisions. No right of any
present or future holder of any Senior Debt to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in
good faith, by any such holder of any Senior Debt or by any non-compliance by
the Company with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof any such holder may have or be otherwise
charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders of the Securities, without
incurring responsibility to the Holders of the Securities and without impairing
or releasing the subordination provided in this Article or the obligations
hereunder of the Holders of the Securities to the holders of Senior Debt, do any
one or more of the following: (a) change the manner, place or terms of payment
or extend the time of payment of, or renew or alter, Senior Debt or otherwise
amend or supplement in any manner Senior Debt or any instrument evidencing the
same or any agreement under which Senior Debt is outstanding; (b) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Debt; (c) release any person liable in any manner for
the collection of Senior Debt; and (d) exercise or refrain from exercising any
rights against the Company and any other person.

                                       63
<PAGE>
         Section 11.5 Notice to Trustee. The Company shall give prompt written
notice to the Trustee of any fact known to the Company that would prohibit the
making of any payment to or by the Trustee in respect of the Securities.
Notwithstanding the provisions of this Article or any other provision of this
Indenture, the Trustee shall not be charged with knowledge of the existence of
any facts that would prohibit the making of any payment to or by the Trustee in
respect of the Securities, unless and until a Responsible Officer of the Trustee
shall have received written notice thereof from the Company or a holder of
Senior Debt or from any trustee, agent or representative therefor; and, prior to
the receipt of any such written notice, the Trustee, subject to the provisions
of Section 5.1, shall be entitled in all respects to assume that no such facts
exist; provided, however, that if the Trustee shall not have received the notice
provided for in this Section 11.5 prior to the date upon which by the terms
hereof any money may become payable for any purpose (including without
limitation the payment of the principal of (and premium, if any) or interest on
any Security), then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such money and to
apply the same to the purpose for which such money was received and shall not be
affected by any notice to the contrary that may be received by it within two
Business Days prior to such date.

         Subject to the provisions of Section 7.1, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a person representing
himself to be a holder of Senior Debt (or a trustee, agent or representative
therefor) to establish that such notice has been given by a holder of Senior
Debt (or a trustee, agent or representative therefor). In the event that the
Trustee determines in good faith that further evidence is required with respect
to the right of any person as a holder of Senior Debt to participate in any
payment or distribution pursuant to this Article XI, the Trustee may request
such person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of Senior Debt held by such person, the extent to which such
person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such person under this Article XI, and if such
evidence is not furnished, the Trustee may defer any payment to such person
pending judicial determination as to the right of such person to receive such
payment.

         Section 11.6 Reliance on Judicial Order of Certificate of Liquidating
Agent. Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 7.1, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the persons entitled to participate in such payment or
distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article.

         Section 11.7 Trustee Not Fiduciary for Holders of Senior Debt. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Debt and shall not be liable to any such holders if it shall in good faith
mistakenly pay over or distribute to Holders of Securities or to the Company or
to any other person cash, property or securities to which any holders of Senior

                                       64
<PAGE>
Debt shall be entitled by virtue of this Article or otherwise. With respect to
the holders of Senior Debt, the Trustee undertakes to perform or to observe only
such of its covenants or obligations as are specifically set forth in this
Article XI, and no implied covenants or obligations with respect to holders of
Senior Debt shall be read into this Indenture against the Trustee.

         Section 11.8 Reliance by Holders of Senior Debt on Subordination
Provisions. Each Holder by accepting a Security acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to each holder of any Senior Debt, whether such Senior Debt
was created or acquired before or after the issuance of the Securities, to
acquire and continue to hold, or to continue to hold, such Senior Debt, and such
holder of Senior Debt shall be deemed conclusively to have relied on such
subordination provisions in acquiring and continuing to hold, or in continuing
to hold, such Senior Debt. Such holders of the Company's Senior Debt are
intended by the parties to the Indenture to be third party creditor
beneficiaries under this Indenture for the purposes of enforcing the provisions
of this Article XI.

         Section 11.9 Rights of Trustee as Holder of Senior Debt; Preservation
of Trustee's Rights. The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article XI with respect to any Senior Debt that
may at any time be held by it, to the same extent as any other holder of Senior
Debt, and nothing in this Indenture shall deprive the Trustee of any of its
rights as such holder.

                  Nothing in this Article XI shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 7.7.

         Section 11.10 Article Applicable to Paying Agents. In case at any time
any Paying Agent other than the Trustee shall have been appointed by the Company
and be then acting hereunder, the term "Trustee" as used in this Article shall
in such case (unless the context otherwise requires) be construed as extending
to and including such Paying Agent within its meaning as fully for all intents
and purposes as if such Paying Agent were named in this Article XI in addition
to or in place of the Trustee; provided, however, that Section 11.9 shall not
apply to the Company or any Affiliate of the Company if it or such Affiliate
acts as Paying Agent.

         Section 11.11 Certain Conversions and Repurchases Deemed Payment. For
the purposes of this Article XI only, (a) the issuance and delivery of junior
securities upon conversion of Securities in accordance with Article X or upon
the repurchase of Securities in accordance with Article III shall not be deemed
to constitute a payment or distribution on account of the principal amount, or
premium or interest or Liquidated Damages Amount on the Securities or on account
of the purchase or other acquisition of Securities, and (b) the payment,
issuance or delivery of cash, property or securities (other than junior
securities) upon conversion of a Security shall be deemed to constitute payment
on account of the principal of such Security. For the purposes of this Section
11.11, the term "junior securities" means (1) shares of any stock of any class
of the Company and (2) securities of the Company that are subordinated in right
of payment to all Senior Debt that may be outstanding at the time of issuance or
delivery of such securities to substantially the same extent as, or to a greater
extent than, the Securities are so subordinated as provided in this Article XI.
Nothing contained in this Article XI or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as among the Company, its creditors
other than

                                       65
<PAGE>
holders of Senior Debt and the Holders of the Securities, the right, which is
absolute and unconditional, of the Holder of any Security to convert such
Security in accordance with Article X or to exchange such Security for Common
Stock in accordance with Article X if the Company elects to satisfy the
obligations under Article III by the delivery of Common Stock.

                                  ARTICLE XII.

                                  MISCELLANEOUS

         Section 12.1 Trust Indenture Act Controls. If any provision of this
Indenture limits, qualifies, or conflicts with another provision which is

         THIS SECURITY AND ANY COMMON STOCK ISSUABLE UPON CONVERSION OF THIS
SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT
BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR
BENEFIT OF UNITED STATES PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.
BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT IT IS (A) A

ACT), (B) AN INSTITUTIONAL "ACCEPTED INVESTOR" (AS DEFINED IN RULE 501 (A) (1),
(2), (3) OR (7) UNDER THE SECURITIES ACT) ("INSTITUTIONAL ACCREDITED INVESTOR")
OR (C) A NON-U.S. PERSON; (2) AGREES THAT IT WILL NOT, PRIOR TO EXPIRATION OF
THE HOLDING PERIOD APPLICABLE TO SALES OF THE SECURITY EVIDENCED HEREBY UNDER
RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), RESELL OR
OTHERWISE TRANSFER THIS SECURITY OR THE COMMON STOCK ISSUABLE UPON CONVERSION

SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT TO A REGISTRATION STATEMENT WHICH
HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE
EFFECTIVE AT THE TIME OF SUCH

                                     A-1-1
<PAGE>
TRANSFER); (3) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO
CLAUSE 2(F) ABOVE), IF THE TRANSFEREE IS AN INSTITUTIONAL ACCEPTED INVESTOR OR
A NON-U.S. PERSON, IT WILL FURNISH TO TRUSTEE, AS TRUSTEE (OR A SUCCESSOR
TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
INFORMATION AS THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER

TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (4) AGREES THAT IT
WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE
SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF
THIS SECURITY PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES
OF THIS SECURITY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR
PROVISION), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE
HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO
[TRUSTEE], AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED
TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR OR IS A PURCHASER WHO IS NOT
A UNITED STATES PERSON, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO
[TRUSTEE], AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH

PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES
ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
REGISTER ANY TRANSFER OF THIS SECURITY IN VIOLATION OF THE FOREGOING
RESTRICTION.

         The foregoing legend may be removed from this Security on satisfaction
of the conditions specified in the Indenture.

                3% CONVERTIBLE SUBORDINATED DEBENTURES DUE 2032

1.       Interest.

         This Security shall bear interest at an initial rate of 3% per year on
the principal amount hereof, from November 22, 2002 or from the most recent
Interest Payment Date (as defined below) to which payment has been paid or duly
provided for, payable semiannually in arrears on April 15 and October 15 of
each year (each, an "Interest Payment Date") to the persons in whose names the
Securities are registered at the close of business on April 1 and October 1
(each, a "Regular Record Date") (whether or not a Business Day), as the case
may be, next preceding such Interest Payment Date. Interest shall be computed
on the basis of a 360-day year comprised of twelve 30-day months.

         Interest on Securities converted during the period after a Regular
Record Date, but prior to the corresponding Interest Payment Date, (i) will not
be required to be paid on the Interest Payment Date if the Security has been
called for redemption on a redemption date that occurs during the period; (ii)
will not be required to be paid if the Security is to be redeemed in connection
with a fundamental change on a redemption date that occurs during this period;
or (iii) if the Security is not called for redemption during this period, will
be paid to the Holder of the Securities on the Regular Record Date but, upon
conversion, the Holder must pay the Company the interest which has accrued and
will be paid on such Interest Payment Date unless at the time of conversion
there is a default in the payment of interest on the Securities.

         If the principal amount of a Security, premium, if any, plus accrued
and unpaid interest, or any portion thereof, is not paid when due (whether upon
acceleration pursuant to Section 6.2 of the Indenture, upon the date set for
payment of the Redemption Price pursuant to Paragraph 5 hereof, upon the date
set for payment of the Purchase Price or the Fundamental Change Purchase Price
pursuant to Paragraph 7 hereof, or upon the Stated Maturity of this Security),
then, in each such case, the overdue amount shall, to the extent permitted by
law, bear interest at the annual rate of 1% above the applicable interest rate
on the Securities, compounded semi-annually, which interest shall accrue from
the date such overdue amount was originally due to the date of payment of such
amount, including interest thereon, has been made or duly provided for. All
such interest shall be payable on demand and shall be based on a 360-day year
comprised of twelve 30-day months.

         Except as provided below, interest and Liquidated Damages Amounts, if
any, will be paid (i) on the Global Securities to the Depositary by wire
transfer in immediately available funds, (ii) on the definitive Securities
having an aggregate principal amount of $2,000,000 or less, by check mailed to
the Holders of such Securities, and (iii) on the definitive Securities having
an aggregate principal amount of more than $2,000,000, by wire transfer in
immediately available funds at the written election of the Holders of these
Securities.

                                     A-1-4
<PAGE>
2.       Method of Payment.

         Subject to the terms and conditions of the Indenture, the Company will
make payments in cash in respect of Redemption Prices, Purchase Prices,
Fundamental Change Purchase Prices and at Stated Maturity to Holders who
surrender Securities to the Paying Agent to collect such payments in respect of
the Securities. The Company will pay cash amounts in money of the United States
that at the time of payment is legal tender for payment of public and private
debts. However, the Company may make such cash payments by wire transfer of
immediately available funds or check payable in such money.

3.       Paying Agent, Conversion Agent and Registrar.

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

4.       Indenture.

         The Company issued the Securities under an Indenture dated as of
November 22, 2002 (the "Indenture"), between the Company and the Trustee. The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act 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
Securities are subject to all such terms, and Securityholders are referred to
the Indenture and the TIA for a statement of those terms. To the extent any
provisions of this Security and the Indenture conflict, the provisions of the
Indenture shall control.

         The Securities are subordinated unsecured obligations of the Company
limited to $150,000,000 aggregate principal amount.

         The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture which has in it the text of this
Security in larger type. Requests may be made to:

                  PacifiCare Health Systems, Inc.
                  5995 Plaza Drive
                  Cypress, California 90630
                  Attn: General Counsel

5.       Redemption at the Option of the Company.

         No sinking fund is provided for the Securities. The Securities are
redeemable at the option of the Company in whole or in part, on or after
October 18, 2007 upon not less than 30 nor more than 60 days' notice by mail
for a redemption price equal to 100.0% of the principal

                                     A-1-5
<PAGE>
amount thereof plus accrued and unpaid interest, if any, to, but excluding,
the Redemption Date (the "Redemption Price"). The redemption price shall be
paid in cash.

6.       Notice of Redemption.

         Notice of redemption pursuant to Paragraph 5 of this Security will be
mailed at least 30 days but not more than 60 days before the Redemption Date to
each Holder of Securities to be redeemed at the Holder's registered address. If
money sufficient to pay the Redemption Price of all Securities or portions
thereof to be redeemed on the Redemption Date is deposited with the Paying
Agent prior to or on the Redemption Date, interest ceases to accrue on such
Securities or portions thereof immediately after such Redemption Date.
Securities 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,
if less than all of the Securities are being redeemed.

7.       Purchase by the Company at the Option of the Holder.

         (a)      Subject to the terms and conditions of the Indenture, the
Company shall become obligated to purchase, at the option of the Holder, all
or any portion of the Securities held by such Holder on any Purchase Date in
integral multiples of $1,000, if less than all of the Securities are being
purchased, at a purchase price equal to 100.0% of the principal amount thereof
plus accrued and unpaid interest, if any, to, but excluding, the Purchase Date.
To exercise such right, a Holder shall deliver to the Company a Purchase Notice
containing the information set forth in the Indenture at any time from the
opening of business on the date that is 20 Business Days prior to such Purchase
Date until the close of business on such Purchase Date, and shall deliver the
Securities to the Paying Agent as set forth in the Indenture.

         The Purchase Price shall be paid in cash.

         (b)      At the option of the Holder and subject to the terms and
conditions of the Indenture, the Company shall become obligated to offer to
purchase the Securities held by such Holder as of a date that is 30 days after
the date of notice of a Fundamental Change delivered by the Company (or, if
such 30th day is not a Business Day, the next succeeding Business Day) for a
purchase price equal to 100.0% of the principal amount thereof plus accrued and
unpaid interest, if any, to, but excluding, the Fundamental Change Purchase
Date. The Company shall mail a written notice of a Fundamental Change by first
class mail to the Trustee and the Holders no later than 10 days after the
occurrence of the Fundamental Change. Such notice shall describe the purchase
right arising as a result of such Fundamental Change. To exercise such purchase
right, a Holder shall deliver to the Company a Fundamental Change Purchase
Notice containing the information set forth in the Indenture at any time prior
to the 30th day after the date of the delivery of the Fundamental Change Notice
and shall deliver the Securities to the Paying Agent as set forth in the
Indenture.

         The Fundamental Change Purchase Price shall be paid in cash.

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

                                     A-1-6
<PAGE>
         If cash sufficient to pay the Purchase Price or Fundamental Change
Purchase Price, as the case may be, of all Securities or portions thereof to be
purchased on the Purchase Date or the Fundamental Change Purchase Date, as the
case may be, is deposited with the Paying Agent on the Purchase Date or the
Fundamental Change Purchase Date, interest ceases to accrue on such Securities
or portions thereof immediately after such Purchase Date or Fundamental Change
Purchase Date, and the Holder thereof shall have no other rights as such other
than the right to receive the Purchase Price or Fundamental Change Purchase
Price upon surrender of such Security.

8.       Conversion.

         (a)      The Securities may be converted into shares of common stock
on the terms and subject to the conditions of the Indenture and this Security.

         (b)      Holders may surrender Securities or portions thereof for
conversion into shares of Common Stock during any calendar quarter if the Sale
Price of the Common Stock for at least 20 trading days in the period of 30
consecutive trading days ending on the last trading day of the previous
calendar quarter exceeds 110% of the applicable Conversion Price per share of
Common Stock on such last trading day.

         (c)      During the five Business Day period after any ten consecutive
trading day period in which the Trading Price per $1,000 principal amount of
the Debentures for each day of such ten day period was less than 95% of the
product of the Sale Price and the number of shares of Common Stock issuable
upon conversion of $1,000 principal amount of the Debentures; PROVIDED that if
on the date of any conversion pursuant to this clause (c) the Sale Price of the
Common Stock is greater than the Conversion Price, a holder shall receive, in
lieu of Common Stock based on the Conversion Price, cash or Common Stock or a
combination of cash and Common Stock, at the Company's option, with a value
equal to the principal amount of the holder's Debentures plus accrued interest
as of the Conversion Date. Any Common Stock delivered pursuant to the foregoing
proviso will be valued at the greater of (i) the Conversion Price on the
conversion date and (ii) the Sale Price on the third trading day after the
conversion date.

         (d)      A Holder also may surrender for conversion a Security or
portion of a Security which has been called for redemption pursuant to
Paragraph 5 hereof, even if the Security would not otherwise be eligible for
conversion, until the close of business on the Business Day immediately
preceding the Redemption Date, unless the Company defaults in making the
payment due on the Redemption Date, in which case the conversion right shall
terminate at the close of business on the date such default is cured and such
payment is made.

         (e)      If the Company (1) distributes any rights or warrants to all
holders of shares of its Common Stock entitling them (for a period expiring
within 45 days of such distribution) to purchase shares of Common Stock at less
than the average of the Sales Prices of a share of the Common Stock for the 10
consecutive trading days ending on the trading day immediately preceding the
date of such distribution or (2) distributes to all holders of shares of its
Common Stock any of its debt securities or assets or any rights, warrants or
options to purchase securities of the Company, which distribution has a per
share value exceeding 10% of the Sales Price on

                                     A-1-7
<PAGE>
the trading day immediately preceding the declaration date for such
distribution, unless the Holder may participate in this distribution without
conversion, the Securities may be surrendered for conversion beginning on the
date the Company gives notice to the Holders of such right, which shall be not
less than 20 days prior to the Ex-Dividend Time for such dividend or
distribution, and the Securities may be surrendered for conversion at any time
thereafter until the close of business on the Business Day immediately
preceding the Ex-Dividend Time or until the Company announces that such
distribution will not take place.

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

         The initial Conversion Rate is 23.8095 shares of Common Stock per
$1,000 principal amount of Securities, subject to adjustment in certain events
described in the Indenture. A Holder that surrenders Securities for conversion
will receive cash or a check, or, at the Company's option, a whole share of
Common Stock, in lieu of any fractional shares of Common Stock.

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

         A Holder may convert a portion of a Security 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 shares of Common Stock except as
provided in the Indenture. Except as provided in Paragraph 1 hereof, on
conversion of a Security, the Holder will not receive any cash payment
representing accrued interest with respect to the converted Securities.
Instead, upon conversion the Company will deliver to the Holder a fixed number
of shares of Common Stock and any cash payment to account for fractional
shares. Accrued interest will be deemed paid in full rather than canceled,
extinguished or forfeited. The Company will not adjust the Conversion Rate to
account for accrued interest.

         The Conversion Rate will be adjusted as provided in Article X of the
Indenture. The Company may increase the Conversion Rate for any period of at
least 20 days, upon at least 15 days' notice so long as the increase is
irrevocable during such period. In addition, the Company may increase the
Conversion Rate if the Board of Directors deems it advisable to avoid or
diminish any income tax to holders of Common Stock resulting from any stock or
rights distribution.

         In addition, if the Company is a party to a consolidation, merger,
binding share exchange or sale of all or substantially all of the Company's
assets, in each case pursuant to which the Company's common stock would be
converted into cash, securities or other property, the Holder may surrender its
debentures for conversion at any time from and after the date which is 15 days
prior to the anticipated effective date of the transaction until and including
the date which is 15

                                     A-1-8
<PAGE>
days after the actual date of such transaction. If the Company is a party to a
consolidation, merger, binding share exchange or sale of all or substantially
all of the Company's assets, in each case pursuant to which the Company's
common stock is converted into cash, securities, or other property, then at the
effective time of the transaction, the Holder's right to convert a debenture
into the Company's common stock will be changed into a right to convert it into
the kind and amount of cash securities and other property which the Holder
would have received if the Holder had converted the its debenture immediately
prior to the transaction.

9.       Conversion Arrangement on Call for Redemption.

         Any Securities called for redemption, unless surrendered for
conversion before the close of business on the Business Day immediately
preceding the Redemption Date, may be deemed to be purchased from the Holders
of such Securities 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 Securities from the Holders, to convert them into shares of
Common Stock and to make payment for such Securities to the Trustee in trust
for such Holders.

10.      Subordination.

         The Securities are subordinated to Senior Debt as provided in the
Indenture. To the extent provided in the Indenture, Senior Debt must be paid
before the Securities may be paid. The Company agrees, and each Securityholder
by accepting a Security agrees, to the subordination and authorizes the Trustee
to give it effect.

11.      Denominations; Transfer; Exchange.

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

12.      Persons Deemed Owners.

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

13.      Unclaimed Money or Securities.

         The Trustee and the Paying Agent shall return to the Company any money
held by them for the payment of any amount with respect to the Securities that
remains unclaimed for two years, subject to applicable unclaimed property law.
After return to the Company, Holders

                                     A-1-9
<PAGE>
entitled to the money or securities must look to the Company for payment as
general creditors unless an applicable abandoned property law designates
another person.

14.      Amendment; Waiver.

         Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities
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 Securities at the time outstanding. Subject to certain exceptions set forth
in the Indenture, without the consent of any Holder, the Company and the
Trustee may amend the Indenture or the Securities among other things, (i) to
cure any ambiguity, omission, defect or inconsistency, provided that such
modification or amendment does not adversely affect the interests of the
Holders of the Securities in any material respect; (ii) to modify the
restrictions on, and procedures for, resale and other transfers of Securities
pursuant to any change in applicable law or regulation (or the interpretation
thereof) or in practice relating to the resale or transfer of "restricted
securities" under the Securities Act generally; (iii) to comply with Article V
or Section 10.16 of the Indenture; (iv) to secure the Company's obligations or
to add any guarantee under the Securities and the Indenture; (v) to add events
of default with respect to the Securities; (vi) to add to the covenants of the
Company for the benefit of the Holders or to surrender any right or power
conferred upon the Company; (vii) to make any change necessary for the
registration of the Securities under the Securities Act or to comply with the
TIA, or any amendment thereto, or to comply with any requirement of the SEC in
connection with the qualification of the Indenture under the TIA, provided that
such modification or amendment does not materially and adversely affect the
interests of the Holders of the Securities; (viii) to provide for
uncertificated Securities in addition to or in place of certificated Securities
or to provide for bearer Securities; (ix) to increase the Conversion Price in
accordance with Paragraph 8 of the Securities; (x) to evidence and provide for
the acceptance of appointment hereunder by a successor Trustee pursuant to
Section 7.8 of the Indenture; or (xi) to add or modify other provisions herein
with respect to matters or questions arising hereunder that the Company and the
Trustee may deem necessary or desirable and that will not materially adversely
affect the interests of the Holders.

15.      Defaults and Remedies.

         Under the Indenture, Events of Default include (i) default in payment
of the principal amount or premium, if any, on any Security when the same
becomes due and payable upon redemption or otherwise, whether or not the
payment is prohibited by the provisions of Article XI of the Indenture; (ii)
default in the payment of any interest or Liquidated Damages Amounts, if any,
when due and payable, and the continuance of such default for a period of 30
days, whether or not the payment is prohibited by the provisions of Article XI
of the Indenture; (iii) failure by the Company to comply in any material
respect with other agreements or covenants in the Indenture or the Securities,
for sixty (60) days after notice; and (iv) certain events of bankruptcy,
insolvency and reorganization of the Company or its Subsidiaries.

         Holders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives

                                     A-1-10
<PAGE>
reasonable indemnity or security. Subject to certain limitations, Holders of a
majority in aggregate principal amount of the Securities at the time
outstanding may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from the Holders notice of any continuing Default (except
a Default in payment of amounts specified in clause (i) or (ii) above) if it
determines that withholding notice is in their interests.

16.      Trustee Dealings with the Company.

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

17.      Calculations in Respect of Securities.

         The Company or its agents will be responsible for making all
calculations called for under the Securities. These calculations include, but
are not limited to, determination of the Sales Prices for the Common Stock, the
rate of interest payable on the Securities and the Conversion Rate of the
Securities. Any calculations made in good faith and without manifest error will
be final and binding on Holders of the Securities. The Company or its agents
will be required to deliver to the Trustee a schedule of its calculations and
each of the Trustee and the Trustee will be entitled to rely upon the accuracy
of such calculations without independent verification. The Trustee will forward
the Company's calculations to any Holder of the Securities upon the request of
such Holder.

18.      Successor Persons.

         When a successor person or other entity assumes all the obligations of
its predecessor under the Securities and the Indenture, the predecessor person
will be released from those obligations.

19.      No Recourse Against Others.

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

20.      Authentication.

         This Security 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 Security.

 21.     Abbreviations.

         Customary abbreviations may be used in the name of a Holder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants

                                     A-1-11

22.      GOVERNING LAW.

ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD AS TO CONFLICT

{Name and Address of Conversion Agent}

                     Re: PacifiCare Health Systems, Inc. 3% Convertible
                         Subordinated Debentures due October 15, 2032
                         (the "Securities")

         Reference is hereby made to the Indenture, dated as of November 22,
2002 (the "Indenture"), between PacifiCare Health Systems, Inc., as Issuer, and
State Street Bank and Trust Company of California, N.A., as Trustee.
Capitalized terms used but not defined herein shall have the meanings given to
them in the Indenture.

         This letter relates to the Securities specified below, which are
registered in the name of the undersigned (the "Holder"). The Holder hereby
irrevocably exercises its right to convert such Securities, or the portion
thereof, if any, specified below, into Common Stock and, except to the extent
specified or required as described below, directs that certificates
representing such Common Stock, together with any check in payment for a
fractional share and any Security representing any unconverted principal
amount, be issued and delivered through the facilities of the Depositary, for
credit to the account(s) of the person(s) indicated below.

         The Holder acknowledges and agrees that no Common Stock will be
delivered on conversion until any amount payable by the Holder on account of
interest is paid, any certificates evidencing specified Securities not held in
book-entry form are duly endorsed or assigned to the Company or in blank and
surrendered and any taxes or other charges or documents required in connection
with a transfer on conversion, and any other required items, are delivered to
the Conversion Agent.

         The Holder acknowledges and agrees that, notwithstanding this request
for conversion, the Company may require that the Common Stock delivered on
conversion of the specified Securities be delivered in certificated form
subject to a restrictive legend, or that additional certifications be delivered
on behalf of the relevant beneficial owner(s), if it determines that doing so
is necessary to comply with the requirements of the Securities Act or
otherwise, as provided in the Indenture.

         Conversion of the specified Securities is subject to the requirements
established by the Company as well as to the procedures of the Depositary, all
as in effect from time to time. The specified Securities will be deemed to have
been converted as of the close of business on the Business Day on which this
conversion notice and all other required items have been delivered to the
Conversion Agent as provided above and, upon such conversion, shall cease to
accrue interest or be outstanding (subject to the Holder's right to receive
the Common Stock as provided in the Indenture). Prior to such conversion, the
Holder will have no rights in the Common Stock.

         Please provide the information requested below, as applicable.

1.    Interest.

      This Security shall bear interest at an initial rate of 3% per year on the
principal amount hereof, from November 22, 2002 or from the most recent Interest
Payment Date (as defined below) to which payment has been paid or duly provided
for, payable semiannually in arrears on April 15 and October 15 of each year
(each, an "Interest Payment Date") to the persons in whose names the Securities
are registered at the close of business on April 1 and October 1 (each, a
"Regular Record Date") (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date. Interest shall be computed on the basis of
a 360-day year comprised of twelve 30-day months.

      Interest on Securities converted during the period after a Regular Record
Date, but prior to the corresponding Interest Payment Date, (i) will not be
required to be paid on the Interest Payment Date if the Security has been called
for redemption on a redemption date that occurs during the period; (ii) will not
be required to be paid if the Security is to be redeemed in connection with a
fundamental change on a redemption date that occurs during this period; or (iii)
if the Security is not called for redemption during this period, will be paid to
the Holder of the Securities on the Regular Record Date but, upon conversion,
the Holder must pay the Company the interest which has accrued and will be paid
on such Interest Payment Date unless at the time of conversion there is a
default in the payment of interest on the Securities.

      If the principal amount of a Security, premium, if any, plus accrued and
unpaid interest, or any portion thereof, is not paid when due (whether upon
acceleration pursuant to Section 6.2 of the Indenture, upon the date set for
payment of the Redemption Price pursuant to Paragraph 5 hereof, upon the date
set for payment of the Purchase Price or the Fundamental Change Purchase Price
pursuant to Paragraph 7 hereof, or upon the Stated Maturity of this Security),
then, in each such case, the overdue amount shall, to the extent permitted by
law, bear interest at the annual rate of 1% above the applicable interest rate
on the Securities, compounded semi-annually, which interest shall accrue from
the date such overdue amount was originally due to the date of payment of such
amount, including interest thereon, has been made or duly provided for. All such
interest shall be payable on demand and shall be based on a 360-day year
comprised of twelve 30-day months.

      Except as provided below, interest and Liquidated Damages Amounts, if any,
will be paid (i) on the Global Securities to the Depositary by wire transfer in
immediately available funds, (ii) on the definitive Securities having an
aggregate principal amount of $2,000,000 or less, by check mailed to the Holders
of such Securities, and (iii) on the definitive Securities having an aggregate
principal amount of more than $2,000,000, by wire transfer in immediately
available funds at the written election of the Holders of these Securities.

                                       1.

2.    Method of Payment.

      Subject to the terms and conditions of the Indenture, the Company will
make payments in cash in respect of Redemption Prices, Purchase Prices,
Fundamental Change Purchase Prices and at Stated Maturity to Holders who
surrender Securities to the Paying Agent to collect such payments in respect of
the Securities. The Company will pay cash amounts in money of the United States
that at the time of payment is legal tender for payment of public and private
debts. However, the Company may make such cash payments by wire transfer of
immediately available funds or check payable in such money.

3.    Paying Agent, Conversion Agent and Registrar.

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

4.    Indenture.

      The Company issued the Securities under an Indenture dated as of November
22, 2002 (the "Indenture"), between the Company and the Trustee. The terms of
the Securities include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act 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 Securities are subject
to all such terms, and Securityholders are referred to the Indenture and the TIA
for a statement of those terms. To the extent any provisions of this Security
and the Indenture conflict, the provisions of the Indenture shall control.

      The Securities are subordinated unsecured obligations of the Company
limited to $135,000,000 aggregate principal amount.

      The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture which has in it the text of this Security in
larger type. Requests may be made to:

            PacifiCare Health Systems, Inc.
            5995 Plaza Drive
            Cypress, California 90630
            Attn:  General Counsel

                                       2.
<PAGE>
5.    Redemption at the Option of the Company.

      No sinking fund is provided for the Securities. The Securities are
redeemable at the option of the Company in whole or in part, on or after October
18, 2007 upon not less than 30 nor more than 60 days' notice by mail for a
redemption price equal to 100.0% of the principal amount thereof plus accrued
and unpaid interest, if any, to, but excluding, the Redemption Date (the
"Redemption Price"). The redemption price shall be paid in cash.

6.    Notice of Redemption.

      Notice of redemption pursuant to Paragraph 5 of this Security will be
mailed at least 30 days but not more than 60 days before the Redemption Date to
each Holder of Securities to be redeemed at the Holder's registered address. If
money sufficient to pay the Redemption Price of all Securities or portions
thereof to be redeemed on the Redemption Date is deposited with the Paying Agent
prior to or on the Redemption Date, interest ceases to accrue on such Securities
or portions thereof immediately after such Redemption Date. Securities 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, if less than all of
the Securities are being redeemed.

7.    Purchase by the Company at the Option of the Holder.

      (a) Subject to the terms and conditions of the Indenture, the Company
shall become obligated to purchase, at the option of the Holder, all or any
portion of the Securities held by such Holder on any Purchase Date in integral
multiples of $1,000, if less than all of the Securities are being purchased, at
a purchase price equal to 100.0% of the principal amount thereof plus accrued
and unpaid interest, if any, to, but excluding, the Purchase Date. To exercise
such right, a Holder shall deliver to the Company a Purchase Notice containing
the information set forth in the Indenture at any time from the opening of
business on the date that is 20 Business Days prior to such Purchase Date until
the close of business on such Purchase Date, and shall deliver the Securities to
the Paying Agent as set forth in the Indenture.

      The Purchase Price shall be paid in cash.

      (b) At the option of the Holder and subject to the terms and conditions of
the Indenture, the Company shall become obligated to offer to purchase the
Securities held by such Holder as of a date that is 30 days after the date of
notice of a Fundamental Change delivered by the Company (or, if such 30th day is
not a Business Day, the next succeeding Business Day) for a purchase price equal
to 100.0% of the principal amount thereof plus accrued and unpaid interest, if
any, to, but excluding, the Fundamental Change Purchase Date. The Company shall
mail a written notice of a Fundamental Change by first class mail to the Trustee
and the Holders no later than 10 days after the occurrence of the Fundamental
Change. Such notice shall describe the purchase right arising as a result of
such Fundamental Change. To exercise such purchase right, a Holder shall deliver
to the Company a Fundamental Change Purchase Notice containing

                                       3.
<PAGE>
the information set forth in the Indenture at any time prior to the 30th day
after the date of the delivery of the Fundamental Change Notice and shall
deliver the Securities to the Paying Agent as set forth in the Indenture.

      The Fundamental Change Purchase Price shall be paid in cash.

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

      If cash sufficient to pay the Purchase Price or Fundamental Change
Purchase Price, as the case may be, of all Securities or portions thereof to be
purchased on the Purchase Date or the Fundamental Change Purchase Date, as the
case may be, is deposited with the Paying Agent on the Purchase Date or the
Fundamental Change Purchase Date, interest ceases to accrue on such Securities
or portions thereof immediately after such Purchase Date or Fundamental Change
Purchase Date, and the Holder thereof shall have no other rights as such other
than the right to receive the Purchase Price or Fundamental Change Purchase
Price upon surrender of such Security.

8.    Conversion.

      (a) The Securities may be converted into shares of common stock on the
terms and subject to the conditions of the Indenture and this Security.

      (b) Holders may surrender Securities or portions thereof for conversion
into shares of Common Stock during any calendar quarter if the Sale Price of the
Common Stock for at least 20 trading days in the period of 30 consecutive
trading days ending on the last trading day of the previous calendar quarter
exceeds 110% of the applicable Conversion Price per share of Common Stock on
such last trading day.

      (c) During the five Business Day period after any ten consecutive trading
day period in which the Trading Price per $1,000 principal amount of the
Debentures for each day of such ten day period was less than 95% of the product
of the Sale Price and the number of shares of Common Stock issuable upon
conversion of $1,000 principal amount of the Debentures; PROVIDED that if on the
date of any conversion pursuant to this clause (c) the Sale Price of the Common
Stock is greater than the Conversion Price, a holder shall receive, in lieu of
Common Stock based on the Conversion Price, cash or Common Stock or a
combination of cash and Common Stock, at the Company's option, with a value
equal to the principal amount of the holder's Debentures plus accrued interest
as of the Conversion Date. Any Common Stock delivered pursuant to the foregoing
proviso will be valued at the greater of (i) the Conversion Price on the
conversion date and (ii) the Sale Price on the third trading day after the
conversion date.

      (d) A Holder also may surrender for conversion a Security or portion of a
Security which has been called for redemption pursuant to Paragraph 5 hereof,
even if the Security would not otherwise be eligible for conversion, until the
close of business on the Business Day immediately preceding the Redemption Date,
unless the Company defaults in making the payment due on the Redemption Date, in
which case the conversion right

                                       4.
<PAGE>
shall terminate at the close of business on the date such default is cured and
such payment is made.

      (e) If the Company (1) distributes any rights or warrants to all holders
of shares of its Common Stock entitling them (for a period expiring within 45
days of such distribution) to purchase shares of Common Stock at less than the
average of the Sales Prices of a share of the Common Stock for the 10
consecutive trading days ending on the trading day immediately preceding the
date of such distribution or (2) distributes to all holders of shares of its
Common Stock any of its debt securities or assets or any rights, warrants or
options to purchase securities of the Company, which distribution has a per
share value exceeding 10% of the Sales Price on the trading day immediately
preceding the declaration date for such distribution, unless the Holder may
participate in this distribution without conversion, the Securities may be
surrendered for conversion beginning on the date the Company gives notice to the
Holders of such right, which shall be not less than 20 days prior to the
Ex-Dividend Time for such dividend or distribution, and the Securities may be
surrendered for conversion at any time thereafter until the close of business on
the Business Day immediately preceding the Ex-Dividend Time or until the Company
announces that such distribution will not take place.

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

      The initial Conversion Rate is 23.8095 shares of Common Stock per $1,000
principal amount of Securities, subject to adjustment in certain events
described in the Indenture. A Holder that surrenders Securities for conversion
will receive cash or a check, or, at the Company's option, a whole share of
Common Stock, in lieu of any fractional shares of Common Stock.

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

      A Holder may convert a portion of a Security 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 shares of Common Stock except as
provided in the Indenture. Except as provided in Paragraph 1 hereof, on
conversion of a Security, the Holder will not receive any cash payment
representing accrued interest with respect to the converted Securities. Instead,
upon conversion the Company will deliver to the Holder a fixed number of shares
of Common Stock and any cash payment to account for fractional shares. Accrued
interest will be deemed paid in full rather than canceled, extinguished or
forfeited. The Company will not adjust the Conversion Rate to account for
accrued interest.

                                       5.
<PAGE>
      The Conversion Rate will be adjusted as provided in Article X of the
Indenture. The Company may increase the Conversion Rate for any period of at
least 20 days, upon at least 15 days' notice so long as the increase is
irrevocable during such period. In addition, the Company may increase the
Conversion Rate if the Board of Directors deems it advisable to avoid or
diminish any income tax to holders of Common Stock resulting from any stock or
rights distribution.

      In addition, if the Company is a party to a consolidation, merger, binding
share exchange or sale of all or substantially all of the Company's assets, in
each case pursuant to which the Company's common stock would be converted into
cash, securities or other property, the Holder may surrender its debentures for
conversion at any time from and after the date which is 15 days prior to the
anticipated effective date of the transaction until and including the date which
is 15 days after the actual date of such transaction. If the Company is a party
to a consolidation, merger, binding share exchange or sale of all or
substantially all of the Company's assets, in each case pursuant to which the
Company's common stock is converted into cash, securities, or other property,
then at the effective time of the transaction, the Holder's right to convert a
debenture into the Company's common stock will be changed into a right to
convert it into the kind and amount of cash securities and other property which
the Holder would have received if the Holder had converted the its debenture
immediately prior to the transaction.

9.    Conversion Arrangement on Call for Redemption.

      Any Securities called for redemption, unless surrendered for conversion
before the close of business on the Business Day immediately preceding the
Redemption Date, may be deemed to be purchased from the Holders of such
Securities 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 Securities from the Holders, to convert them into shares of Common
Stock and to make payment for such Securities to the Trustee in trust for such
Holders.

10.   Subordination.

      The Securities are subordinated to Senior Debt as provided in the
Indenture. To the extent provided in the Indenture, Senior Debt must be paid
before the Securities may be paid. The Company agrees, and each Securityholder
by accepting a Security agrees, to the subordination and authorizes the Trustee
to give it effect.

11.   Denominations; Transfer; Exchange.

      The Securities are in fully registered form, without coupons, in minimum
denominations of $1,000 of principal amount and integral multiples of $1,000. A
Holder may transfer or exchange the Securities in accordance with the Indenture.
The Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar need not transfer or exchange
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the

                                       6.
<PAGE>
Security not to be redeemed) or any Securities in respect of which a Purchase
Notice or Fundamental Change Purchase Notice has been given and not withdrawn
(except, in the case of a Security to be purchased in part, the portion of the
Security not to be purchased) or any Securities for a period of 15 days before
the mailing of a notice of redemption of Securities to be redeemed.

12.   Persons Deemed Owners.

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

13.   Unclaimed Money or Securities.

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

14.   Amendment; Waiver.

      Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities
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
Securities at the time outstanding. Subject to certain exceptions set forth in
the Indenture, without the consent of any Holder, the Company and the Trustee
may amend the Indenture or the Securities among other things, (i) to cure any
ambiguity, omission, defect or inconsistency, provided that such modification or
amendment does not adversely affect the interests of the Holders of the
Securities in any material respect; (ii) to modify the restrictions on, and
procedures for, resale and other transfers of Securities pursuant to any change
in applicable law or regulation (or the interpretation thereof) or in practice
relating to the resale or transfer of "restricted securities" under the
Securities Act generally; (iii) to comply with Article V or Section 10.16 of the
Indenture; (iv) to secure the Company's obligations or to add any guarantee
under the Securities and the Indenture; (v) to add events of default with
respect to the Securities; (vi) to add to the covenants of the Company for the
benefit of the Holders or to surrender any right or power conferred upon the
Company; (vii) to make any change necessary for the registration of the
Securities under the Securities Act or to comply with the TIA, or any amendment
thereto, or to comply with any requirement of the SEC in connection with the
qualification of the Indenture under the TIA, provided that such modification or
amendment does not materially and adversely affect the interests of the Holders
of the Securities; (viii) to provide for uncertificated Securities in addition
to or in place of certificated Securities or to provide for bearer Securities;
(ix) to increase the Conversion Price in accordance with Paragraph 8 of the
Securities; (x) to evidence and provide for the acceptance of appointment
hereunder by a successor Trustee pursuant to

                                       7.
<PAGE>
Section 7.8 of the Indenture; or (xi) to add or modify other provisions herein
with respect to matters or questions arising hereunder that the Company and the
Trustee may deem necessary or desirable and that will not materially adversely
affect the interests of the Holders.

15.   Defaults and Remedies.

      Under the Indenture, Events of Default include (i) default in payment of
the principal amount or premium, if any, on any Security when the same becomes
due and payable upon redemption or otherwise, whether or not the payment is
prohibited by the provisions of Article XI of the Indenture; (ii) default in the
payment of any interest or Liquidated Damages Amounts, if any, when due and
payable, and the continuance of such default for a period of 30 days, whether or
not the payment is prohibited by the provisions of Article XI of the Indenture;
(iii) failure by the Company to comply in any material respect with other
agreements or covenants in the Indenture or the Securities, for sixty (60) days
after notice; and (iv) certain events of bankruptcy, insolvency and
reorganization of the Company or its Subsidiaries.

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

16.   Trustee Dealings with the Company.

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

17.   Calculations in Respect of Securities.

      The Company or its agents will be responsible for making all calculations
called for under the Securities. These calculations include, but are not limited
to, determination of the Sales Prices for the Common Stock, the rate of interest
payable on the Securities and the Conversion Rate of the Securities. Any
calculations made in good faith and without manifest error will be final and
binding on Holders of the Securities. The Company or its agents will be required
to deliver to the Trustee a schedule of its calculations and each of the Trustee
and the Trustee will be entitled to rely upon the accuracy of such calculations
without independent verification. The Trustee will forward the Company's
calculations to any Holder of the Securities upon the request of such Holder.

                                       8.
<PAGE>
18.   Successor Persons.

      When a successor person or other entity assumes all the obligations of its
predecessor under the Securities and the Indenture, the predecessor person will
be released from those obligations.

19.   No Recourse Against Others.

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

      This Security 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 Security.

               {NOTICE PURSUANT TO SECTION 10.2 OF THE INDENTURE}

{Name and Address of Conversion Agent}

                  Re:   PacifiCare Health Systems, Inc. 3% Convertible
                        Subordinated Debentures due October 15, 2032 (the
                        "Securities")

      Reference is hereby made to the Indenture, dated as of November 22, 2002
(the "Indenture"), between PacifiCare Health Systems, Inc., as Issuer, and U.S.
Bank National Association, as Trustee. Capitalized terms used but not defined
herein shall have the meanings given to them in the Indenture.

      This letter relates to the Securities specified below, which are
registered in the name of the undersigned (the "Holder"). The Holder hereby
irrevocably exercises its right to convert such Securities, or the portion
thereof, if any, specified below, into Common Stock and, except to the extent
specified or required as described below, directs that certificates representing
such Common Stock, together with any check in payment for a fractional share and
any Security representing any unconverted principal amount, be issued and
delivered through the facilities of the Depositary, for credit to the account(s)
of the person(s) indicated below.

      The Holder acknowledges and agrees that no Common Stock will be delivered
on conversion until any amount payable by the Holder on account of interest is
paid, any certificates evidencing specified Securities not held in book-entry
form are duly endorsed or assigned to the Company or in blank and surrendered
and any taxes or other charges or documents required in connection with a
transfer on conversion, and any other required items, are delivered to the
Conversion Agent.

      The Holder acknowledges and agrees that, notwithstanding this request for
conversion, the Company may require that the Common Stock delivered on
conversion of the specified Securities be delivered in certificated form subject
to a restrictive legend, or that additional certifications be delivered on
behalf of the relevant beneficial owner(s), if it determines that doing so is
necessary to comply with the requirements of the Securities Act or otherwise, as
provided in the Indenture.

      Conversion of the specified Securities is subject to the requirements
established by the Company as well as to the procedures of the Depositary, all
as in effect from time to time. The specified Securities will be deemed to have
been converted as of the close of business on the Business Day on which this
conversion notice and all other required items have been delivered to the
Conversion Agent as provided above and, upon such conversion, shall cease to
accrue interest or be outstanding (subject to the Holder's right to receive the
Common Stock as provided in the Indenture). Prior to such conversion, the Holder
will have no rights in the Common Stock.

      Please provide the information requested below, as applicable.

                                       1.

      and other information, and if box (d) is checked such legal opinions, as
      the Company has reasonably requested in writing, by delivery to the
      transfer agent of a standing letter of instruction, to confirm that such
      transfer is being made pursuant to an exemption from, or in a transaction
      not subject to, the registration requirements of the Securities Act of
      1933.
