have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depositary or by the Trustee as the custodian of the
Depositary or under such Global Security, and the Depositary may be treated by

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 impair, as between the Depositary and its Agent Members, the operation of
customary practices of such Depositary governing the exercise of the rights of a

and "Terms and Conditions Governing Use of Euroclear" and the "Management

signature of the Trustee. The signature shall be conclusive evidence that the
Security has been authenticated under this Indenture.

aggregate principal amount of $115,000,000. The aggregate principal amount of
Securities outstanding at any time may not exceed that amount except as provided

Company to authenticate Securities. An authenticating agent may authenticate

authentication by the Trustee includes authentication by such agent. An

exchange ("Registrar"); (ii) an office or agency where Securities may be
presented for payment ("Paying Agent"); (iii) an office or agency where
Securities may be presented for conversion (the "Conversion Agent"); and (iv) an
office or agency where notices and demands to or upon the Company in respect of
Securities and this Indenture may be served by the holders of the Securities.
The Registrar shall keep a Register ("Register") of the Securities and of their
transfer and exchange. The Company may appoint one or more co-registrars, one or
more additional paying agents and one or more additional conversion agents. The
term "Registrar" includes any co-registrar, the term "Paying Agent" includes any
additional paying agent and the term "Conversion Agent" includes any additional
Conversion Agent. The Company may change any Paying Agent, Registrar or
Conversion Agent without prior notice. The Company shall notify the Trustee of
the name and address of any Agent not a party to this Indenture and shall enter
into an appropriate agency agreement with any Registrar, Paying Agent or
Conversion Agent not a party to this Indenture. The agreement shall implement
the provisions of this Indenture that relate to such Agent. The Company or any
of its Subsidiaries may act as Registrar, Paying

                                      -10-
<PAGE>
Agent or Conversion Agent, except that, for purposes of Article 8, neither the
Company nor any of its Subsidiaries shall act as Paying Agent. If the Company
fails to appoint or maintain another entity as Registrar, Paying Agent or
Conversion Agent, the Trustee shall initially act as such.

SECTION 2.04 Paying Agent To Hold Money in Trust.

         The Company shall require each Paying Agent (other than the Trustee,
who hereby so agrees) to agree in writing that the Paying Agent will hold in
trust for the benefit of holders of the Securities or the Trustee all money held
by the Paying Agent for the payment of principal of, premium, if any, interest
or Additional Amounts, if any, on the Securities, and will notify the Trustee of
any default by the Company in respect of making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held
by it to the Trustee. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary of the Company) shall
have no further liability for the money. If the Company or a Subsidiary of the
Company acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the holders of the Securities all money held by it as
Paying Agent.

SECTION 2.05 Holder 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
holders of Securities and shall otherwise comply with TIA Section 312(a). If the
Trustee is not the Registrar, the Company shall furnish to the Trustee at least
seven business days before each Interest Payment Date, and as the Trustee may
request in writing within fifteen days after receipt by the Company of any such
request (or such lesser time as the Trustee may reasonably request in order to
enable it to timely provide any notice to be provided by it hereunder), a list
in such form and as of such date as the Trustee may reasonably require of the
names and addresses of holders of Securities.

SECTION 2.06 Transfer and Exchange.

         (a) When Securities are presented to the Registrar with a request to
register a transfer or to exchange them for an equal principal amount of
Securities for other denominations, the Registrar shall register the transfer or
make the exchange if its requirements for such transactions are met. To permit
registrations of transfers and exchanges, the Company shall issue and the
Trustee shall authenticate Securities at the Registrar's request, bearing
registration numbers not contemporaneously outstanding. No service charge shall
be made to a holder for any registration of transfer or exchange (except as
otherwise expressly permitted herein), but the Company and the Registrar may
require payment of a sum sufficient to cover any transfer tax or other
governmental charge payable upon exchanges pursuant to Sections 2.07, 3.09, 9.05
or 11.02.

         The Company or the Registrar shall not be required (i) to issue,
register the transfer of or exchange Securities during a period beginning at the
opening of fifteen days before the day of mailing of a notice of redemption of
Securities under Section 3.02 and ending at the close of business on the day of
such mailing, (ii) to register the transfer or exchange of any Security so
selected for redemption in whole or in part, except the unredeemed portion of
any Security being redeemed in part or (iii) to register the transfer of any
Securities surrendered for repurchase pursuant to Sections 3.08 or 3.14.

         All Securities issued upon any transfer or exchange of Securities in
accordance with this Indenture shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the

                                      -11-
<PAGE>
same benefits under this Indenture as the Securities surrendered upon such
registration of transfer or exchange.

         (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, or of any
beneficial interest therein, shall only be made in accordance with Sections
2.01(c) and 2.10; 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 "Notice to Investors" in the Offering
Memorandum and, if applicable, in the Restricted Securities Legend.

         Except for transfers or exchanges made in accordance with Section 2.10,
transfers of a Global Security shall be limited to transfers of such Global
Security in whole, but not in part, by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or nominee.

         In the event that a Global Security is exchanged for certificated
Securities in definitive form pursuant to Section 2.10(c) 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 (i) such Global Security or
such Securities in definitive form, duly endorsed as provided herein, as
applicable, (ii) 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 (iii)
such certifications or other information (including, without limitation, those
set forth on the Security) 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 or Regulation S under the Securities Act, as the
case may be), and upon compliance with such other procedures as may from time to
time be adopted by the Company and the Registrar.

         If (i) shares of Common Stock to be issued upon conversion of any
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 a
Shelf Registration Statement has become effective and such shares are being
transferred pursuant to such Shelf Registration Statement, the holder must
deliver to the transfer agent for the Common Stock a certificate in
substantially the form of Exhibit C 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 in connection with a Shelf Registration Statement
contemplated by and in accordance with the terms of the Registration Rights
Agreement, if Securities are issued upon the registration of transfer, exchange
or replacement of Securities bearing a Restricted Securities Legend, or if a
request is made to remove such a Restrictive Securities Legend on the
Securities, the Securities so

                                      -12-
<PAGE>
issued shall bear the Restricted Securities Legend, or a Restricted Securities
Legend shall not be removed, as the case may be, unless there is delivered to
the Company such satisfactory evidence, which, in the case of a transfer made
pursuant to Rule 144 under the Securities Act, 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 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 Securities are not "restricted" within the
meaning of Rule 144 under the Securities Act. Upon provision to the Company of
such satisfactory evidence, the Trustee, at the written direction of the
Company, shall authenticate and deliver Securities that do not bear the legend.
The Company shall not otherwise be entitled to require the delivery of a legal
opinion in connection with any transfer or exchange of Securities.

         (d) Neither the Trustee nor any Agent shall have any responsibility for
any actions taken or not taken by the Depositary.

         (e) 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 Securities (including any transfers between or among the Depositary's
participants or beneficial owners of interests in any Global Security) other
than to require delivery of such certificates and other documentation as is
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.

         (f) Each holder of a Security agrees to indemnify the Company and the
Trustee against any liability that may result from the transfer, exchange or
assignment of such holder's Security in violation of any provision of this
Indenture and/or applicable United States federal or state securities law.

SECTION 2.07 Replacement Securities.

         If the holder of a Security claims that its Security has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall
authenticate a replacement Security if the Trustee's and the Company's
requirements are met. As a condition of receiving a replacement Security, the
holder of a Security must provide a certificate of loss and an indemnity and/or
an indemnity bond sufficient, in the judgment of both the Company and the
Trustee, to fully protect the Company, the Trustee, any Agent and any
authenticating agent from any loss, liability, cost or expense which any of them
may suffer or incur if the Security is replaced. The Company and the Trustee may
charge the relevant holder for their expenses in replacing any Security.

         The Trustee or any authenticating agent may authenticate any such
substituted Security, and deliver the same upon the receipt of such security or
indemnity as the Trustee and the Company may require. Upon the issuance of any
substituted Security, the Company and the Trustee 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 connected therewith. In case any
Security which has matured or is about to mature, or has been called for
redemption pursuant to Article 3, submitted for repurchase pursuant to Sections
3.08 or 3.14 or is about to be converted into Common Stock pursuant to Article
11, shall become mutilated or be destroyed, lost or stolen, the Company may,
instead of issuing a substitute Security, pay or authorize the payment of or
convert or authorize the conversion of the same (without surrender thereof
except in the case of a mutilated Security), as the case may be, if the
applicant for such payment or conversion shall furnish to the Company, to the
Trustee and, if applicable, to the Paying Agent or Conversion Agent such
security or indemnity as may be required by the Company or the Trustee

                                      -13-
<PAGE>
to save each of them harmless for any loss, liability, cost or expense caused by
or connected with such substitution, and, in case of destruction, loss or theft,
evidence satisfactory to the Company, the Trustee and, if applicable, the Paying
Agent or Conversion Agent of the destruction, loss or theft of such Security and
of the ownership thereof.

         Every replacement Security is an additional obligation of the Company
and shall be entitled to all the benefits provided under this Indenture equally
and proportionately with all other Securities duly issued, authenticated and
delivered hereunder.

SECTION 2.08 Outstanding Securities.

         The Securities outstanding at any time are all the Securities properly
authenticated by the Trustee except for those canceled by the Trustee, those
paid pursuant to Section 2.07, those delivered to it for cancellation and those
described in this Section as not outstanding.

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

         If Securities are considered paid under Section 4.01 or converted under
Article 11, they cease to be outstanding, and interest and Additional Amounts,
if any, on them ceases to accrue.

         Subject to Section 2.09 hereof, a Security does not cease to be
outstanding because the Company or an Affiliate of the Company holds the
Security.

SECTION 2.09 When Treasury Securities Disregarded.

         In determining whether the holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned
by the Company or an Affiliate of the Company shall be considered as though they
are not outstanding except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Securities which a Trust Officer of the Trustee actually knows are so owned
shall be so disregarded.

SECTION 2.10 Temporary Securities.

         (a) Until definitive Securities are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form of definitive Securities but may
have variations that the Company considers appropriate for temporary Securities
and shall be reasonably acceptable to the Trustee. Without unreasonable delay,
the Company shall prepare and the Trustee shall authenticate definitive
Securities in exchange for temporary Securities.

         (b) A Global Security deposited with the Depositary or with the Trustee
as custodian for the Depositary pursuant to Section 2.01 shall be transferred to
the beneficial owners thereof in the form of certificated Securities in
definitive form only if such transfer complies with Section 2.06 and (i) the
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such Global Security or if at any time such Depositary ceases to
be a "clearing agency" registered under the Exchange Act and a successor
Depositary is not appointed by the Company within 90 days of such notice or the
Company decides to discontinue the use of Global Securities, or (ii) an Event of
Default has occurred and is continuing.

                                      -14-
<PAGE>
         (c) Any Global Security or interest thereon that is transferable to the
beneficial owners thereof in the form of certificated Securities in definitive
form shall, if held by the Depositary, be surrendered by the Depositary to the
Trustee, without charge, and the Trustee shall authenticate and deliver, upon
such transfer of each portion of such Global Security, an equal aggregate
principal amount of Securities of authorized denominations in the form of
certificated Securities in definitive form. Any portion of a Global Security
transferred pursuant to this Section shall be executed, authenticated and
delivered only in denominations of $1,000 and any integral multiple thereof and
registered in such names as the Depositary shall direct. Any Securities in the
form of certificated Securities in definitive form delivered in exchange for an
interest in the Global Security shall, except as otherwise provided by Section
2.06(c), bear the Restricted Securities Legend set forth in Exhibit A hereto.

         (d) Prior to any transfer pursuant to Section 2.10(b), the registered
holder of a Global Security 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.

SECTION 2.11 Cancellation.

         The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else may cancel Securities surrendered for
registration of transfer, exchange, payment, replacement, conversion,
redemption, repurchase or cancellation. Upon written instructions of the
Company, the Trustee shall dispose of canceled Securities in accordance with its
procedures for the disposition of canceled securities in effect as of the date
of such disposition. The Company may not issue new Securities to replace
Securities that it has paid, redeemed or repurchased or that have been delivered
to the Trustee for cancellation or that any holder has (i) converted pursuant to
Article 11 hereof, (ii) submitted for redemption pursuant to Article 3 hereof or
(iii) submitted for repurchase pursuant to Sections 3.08 or 3.14 hereof (unless
revoked).

SECTION 2.12 Defaulted Interest.

         If the Company fails to make a payment of interest on the Securities
("defaulted interest"), it shall pay such defaulted interest plus, to the extent
lawful, any interest payable on the defaulted interest. It may pay such
defaulted interest, plus any such interest payable on it, to the persons who are
holders of Securities on a subsequent special record date. The Company shall fix
any such record date and payment date. At least 15 days before any such record
date, the Company shall mail to holders of the Securities a notice that states
the record date, payment date and amount of such interest to be paid.

SECTION 2.13 CUSIP Number.

         The Company in issuing the Securities may use a "CUSIP" number, and if
so, such CUSIP number shall be included in notices of redemption, repurchase or
exchange as a convenience to holders of Securities; provided, however, that any
such notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number printed in the notice or on the Securities and that
reliance may be placed only on the other identification numbers printed on the
Securities. The Company will promptly notify the Trustee of any change in the
CUSIP number.

                                      -15-
<PAGE>
SECTION 2.14 Regulation S.

         The Company agrees that it will refuse to register any transfer of
Securities or any shares of Common Stock issued upon conversion of Securities
that is not made in accordance with the provisions of Regulation S under the
Securities Act, pursuant to a registration statement which has been declared
effective under the Securities Act or pursuant to an available exemption from
the registration requirements of the Securities Act; provided that the
provisions of this paragraph shall not be applicable to any Securities which do
not bear a Restricted Securities Legend or to any shares of Common Stock
evidenced by certificates which do not bear a Restricted Common Stock Legend.

                                   ARTICLE 3

                            REDEMPTION AND PURCHASES

SECTION 3.01 Right to Redeem; Notices to Trustee.

         Prior to June 18, 2006, the Company cannot redeem the Securities (other
than pursuant to Section 3.14). Beginning on June 18, 2006, the Company may
redeem the Securities for cash in whole at any time, or in part from time to
time, in accordance with the provisions of paragraph 5 of the Securities.

         If the Company elects to redeem Securities pursuant to paragraph 5 of
the Securities, it shall notify the Trustee in writing of the Redemption Date,
the principal amount of Securities to be redeemed, the Redemption Price and the
amount of any accrued and unpaid interest, Additional Amounts or Make Whole
Payment payable on the Redemption Date. The Company shall give the notice to the
Trustee provided for in this Section 3.01 by an Officers' Certificate at least
45 days before the Redemption Date (unless a shorter notice shall be
satisfactory to the Trustee). If fewer than all the Securities are to be
redeemed, the record date relating to such redemption shall be selected by the
Company and given to the Trustee, which record date shall not be less than ten
days after the date of notice to the Trustee.

SECTION 3.02 Selection of Securities to be Redeemed.

         If less than all the Securities are to be redeemed at any time,
selection of the Securities for redemption shall be made by the Trustee in
compliance with the requirements of the principal national securities exchange,
if any, on which the Securities are listed or, if the Securities are not so
listed, on a pro rata basis, by lot or by any other method that the Trustee
considers fair and appropriate. The Trustee shall make the selection at least 30
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 a portion of the principal amount
of any Securities that have a denomination larger than $1,000. Securities and
portions thereof shall be redeemed in the amount of $1,000 or integral multiples
of $1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption. The
Trustee shall notify the Company promptly of the Securities or portions of
Securities to be redeemed.

         The Trustee shall make the selection from Securities outstanding and
not previously called for redemption. 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

                                      -16-
<PAGE>
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 3.03 Notice of Redemption.

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

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

         (a) the Redemption Date;

         (b) the Redemption Price and any accrued and unpaid interest,
Additional Amounts or Make Whole Payment payable on the Redemption Date;

         (c) the Conversion Rate and Conversion Price and whether any Securities
converted after the notice of redemption will be settled in cash or shares of
Common Stock;

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

         (e) that Securities called for redemption may be converted at any time
before the close of business on the trading day immediately preceding the
Redemption Date, unless the Company Defaults in the payment of the Redemption
Price, in which case the conversion right will terminate at the close of
business on the date such Default is cured;

         (f) that holders who want to convert Securities must satisfy the
requirements set forth in paragraph 15 of the Securities;

         (g) that Securities called for redemption must be surrendered to the
Paying Agent to collect the Redemption Price and any accrued and unpaid cash
interest, Additional Amounts or Make Whole Payment;

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

         (i) that, unless the Company defaults in making payment of such
Redemption Price and any interest, Additional Amounts or Make Whole Payment
which is due and payable, any interest and Additional Amounts will cease to
accrue on and after the Redemption Date;

         (j) the CUSIP number of the Securities; and

         (k) any other information the Company wants to present.

         At the Company's request, the Trustee shall give the notice of
redemption to holders in the Company's name and at the Company's expense,
provided that the Company makes such request at least five business days (unless
a shorter period shall be satisfactory to the Trustee) prior to the date such
notice of redemption must be mailed.

                                      -17-
<PAGE>
SECTION 3.04 Effect of Notice of Redemption.

         Once a notice of redemption is given, Securities called for redemption
become due and payable on the Redemption Date and at the Redemption Price
(together with accrued and unpaid interest and any Additional Amounts to, but
excluding, the Redemption Date and any Make Whole Payment) 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 (together with accrued and unpaid interest and any
Additional Amounts to, but excluding, the Redemption Date and any Make Whole
Payment) stated in the notice.

SECTION 3.05 Deposit of Redemption Price.

         Prior to 10:00 a.m., New York City time, on any Redemption Date, the
Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary
or an Affiliate of either of them is the Paying Agent, shall segregate and hold
in trust) money sufficient to pay the Redemption Price of, and accrued and
unpaid interest and any Additional Amounts to, but excluding, the Redemption
Date and any Make Whole Payment with respect to, 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, together with interest
or dividends thereon, if any, not required for that purpose because of
conversion of Securities pursuant to Article 11. If such money is then held by
the Company in trust and is not required for such purpose it shall be discharged
from such trust.

SECTION 3.06 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 3.07 Conversion Arrangement on Call for Redemption.

         In connection with any redemption of Securities, the Company may
arrange for the purchase and conversion of any Securities called for redemption
by an agreement with one or more investment banks or other purchasers to
purchase such Securities by paying to the Trustee in trust for the holders of
Securities, on or prior to 10:00 a.m. New York City time on the Redemption Date,
an amount that, together with any amounts deposited with the Trustee by the
Company for the redemption of such Securities, is not less than the Redemption
Price of, and any accrued and unpaid interest, Additional Amounts or Make Whole
Payment due with respect to, such Securities. Notwithstanding anything to the
contrary contained in this Article 3, the obligation of the Company to pay the
Redemption Prices and any accrued and unpaid interest, Additional Amounts or
Make Whole Payments on such Securities shall be deemed to be satisfied and
discharged to the extent such amount is so paid by such purchasers. If such an
agreement is entered into, any Securities not duly surrendered for conversion by
the holders thereof may, at the option of the Company, be deemed, to the fullest
extent permitted by law, acquired by such purchasers from such holders and
(notwithstanding anything to the contrary contained in Article 11) surrendered
by such purchasers for conversion, all as of immediately prior to the close of
business on the trading day immediately prior to the Redemption Date, subject to
payment of the above amounts as aforesaid. The Trustee shall hold and pay to the
holders whose Securities are selected for redemption any such amounts paid to it
for purchase and conversion in the same manner as it would moneys deposited with
it by the Company for the redemption of Securities. Without the Trustee's prior
written consent, no arrangement

                                      -18-
<PAGE>
between the Company and such purchasers for the purchase and conversion of any
Securities shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Trustee as set forth in this Indenture,
and the Company agrees to indemnify the Trustee from, and hold it harmless
against, any loss, liability or expense arising out of or in connection with any
such arrangement for the purchase and conversion of any Securities between the
Company and such purchasers, including the costs and expenses incurred by the
Trustee in the defense of any claim or liability arising out of or in connection
with the exercise or performance of any of its powers, duties, responsibilities
or obligations under this Indenture.

SECTION 3.08 Repurchase of Securities at Option of the Holder.

         (a) Securities shall be purchased by the Company pursuant to the terms
of the Securities at the option of any holder of Securities on June 15, 2013 and
June 15, 2018 (each, a "Repurchase Date"), at a purchase price of 100% of the
principal amount plus any accrued and unpaid interest and any Additional Amounts
(the "Repurchase Price"), in each case, to, but excluding, such Repurchase Date,
subject to the provisions of Section 3.09. Repurchases of Securities under this
Section 3.08 shall be made, at the option of the holder thereof, upon:

                  (i) delivery to the Paying Agent by a holder of Securities of
a written notice (a "Repurchase Notice") during the period beginning at any time
from the opening of business on the date that is twenty business days prior to
the applicable relevant Repurchase Date until the close of business on the third
business day prior to such Repurchase Date stating:

                           (1) the certificate numbers, if any, which the holder
                           will deliver to be purchased or the appropriate
                           Depositary information if the Security in respect of
                           which such notice of withdrawal is being submitted is
                           represented by a Global Security,

                           (2) the portion of the principal amount of the
                           Securities which the holder will deliver to be
                           purchased, which portion must be a principal amount
                           of $1,000 or an integral multiple thereof,

                           (3) that such Security shall be purchased as of the
                           Repurchase Date pursuant to the terms and conditions
                           specified in paragraph 6 of the Securities and in
                           this Indenture, and

                           (4) in the event the Company elects, pursuant to
                           Section 3.09, to pay the Repurchase Price to be paid
                           as of such Repurchase Date in shares of Common Stock
                           but such portion of the Repurchase Price shall
                           ultimately be payable to such holder entirely in cash
                           because any of the conditions to payment of the
                           Repurchase Price in Common Stock is not satisfied
                           prior to the close of business on such Repurchase
                           Date, as set forth in Section 3.09(c), whether such
                           holder elects: (1) to withdraw such Repurchase Notice
                           as to some or all of the Securities to which such
                           Repurchase Notice relates (stating the principal
                           amount and certificate numbers, if any, of the
                           Securities as to which such withdrawal shall relate),
                           or (2) to receive cash in respect of the entire
                           Repurchase Price for all Securities (or portions
                           thereof) to which such Repurchase Notice relates; and

                                      -19-
<PAGE>
                  (ii) delivery or book-entry transfer of the Securities to
Paying Agent at any time after delivery of the applicable Repurchase Notice
(together with all necessary endorsements) at the office of the Paying Agent,
such delivery being a condition to receipt by the holder of the Repurchase Price
therefor; provided that such Repurchase Price shall be so paid pursuant to this
Section 3.08 only if the Security so delivered to Paying Agent shall conform in
all respects to the description thereof in the related Repurchase Notice.

         (b) If the Company has elected to pay the Repurchase Price in shares of
Common Stock, but is unable to deliver the shares of Common Stock, a holder of
Securities, in such holder's Repurchase Notice and in any written notice of
withdrawal delivered by such holder pursuant to the terms of Section 3.10, may
elect to withdraw the Repurchase Notice or to receive cash. If a holder fails to
indicate in its Repurchase Notice its election to receive cash or Common Stock,
the holder shall be deemed to have elected to receive cash in respect of the
entire Repurchase Price for all Securities subject to such Repurchase Notice.

         The Company shall purchase from the holder thereof, pursuant to this
Section 3.08, a portion of a Security, only if the principal amount of such
portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the purchase of all of a Security also apply to the
purchase of such portion of such Security.

         Any purchase by the Company contemplated pursuant to the provisions of
this Section 3.08 shall be consummated by the delivery of the consideration to
be received by the holder promptly following the later of the Repurchase Date
and the time of the book-entry transfer or delivery of the Security.

         Notwithstanding anything herein to the contrary, any holder of
Securities delivering to the Paying Agent the Repurchase Notice contemplated by
this Section 3.08 shall have the right to withdraw such Repurchase Notice at any
time prior to the close of business on the Repurchase Date by delivery of a
written notice of withdrawal to the Paying Agent in accordance with Section
3.10.

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

SECTION 3.09 Company's Right to Elect Manner of Payment of Repurchase Price.

         (a) The Securities to be repurchased on any Repurchase Date pursuant to
Section 3.08 may be paid for at the election of the Company, in cash or Common
Stock, subject to the conditions set forth in Sections 3.09(c) and (d). The
Company shall designate, in the Company Repurchase Notice delivered pursuant to
Section 3.09(d), whether the Company will repurchase the Securities for cash or
shares of Common Stock; provided that the Company will pay cash for fractional
interests in shares of Common Stock. For purposes of determining the existence
of potential fractional interests, all Securities subject to repurchase by the
Company held by a holder shall be considered together (no matter how many
separate certificates are to be presented). The Company may not change its
election with respect to the consideration to be paid once the Company has given
its Company Repurchase Notice to holders except pursuant to Section 3.09(c) in
the event of a failure to satisfy, prior to the close of business on the
business day immediately preceding the Repurchase Date, any condition to the
payment of the Repurchase Price in shares of Common Stock.

         At least three business days before each Company Repurchase Notice
Date, the Company shall deliver an Officers' Certificate to the Trustee
specifying:

                                      -20-
<PAGE>
            (i) the manner of payment selected by the Company,

            (ii) the information required by Section 3.09(d) in the Company
Repurchase Notice,

            (iii) if the Company elects to pay the Repurchase Price in shares of
Common Stock, that the conditions to such manner of payment set forth in Section
3.09(c) have been or will be complied with, and

            (iv) whether the Company desires the Trustee to give the Company
Repurchase Notice required by Section 3.09(d).

      (b) At the option of the Company, the Repurchase Price of Securities in
respect of which a Repurchase Notice pursuant to Section 3.08 has been given may
be paid by the Company entirely in cash or in shares of Common Stock. The
Company Repurchase Notice, as provided in Section 3.09(d), shall be sent to
holders not less than 30 business days prior to such Repurchase Date (the
"Company Repurchase Notice Date").

      (c) At the option of the Company, the Repurchase Price of Securities in
respect of which a Repurchase Notice pursuant to Section 3.08 has been given may
be paid by the Company by the issuance of a number of shares of Common Stock
equal to the quotient obtained by dividing the Repurchase Price by 97.5% of the
average of the Closing Sale Price of the shares of Common Stock for the
twenty-trading day period immediately preceding and ending on the third business
day prior to the applicable Repurchase Date, appropriately adjusted to take into
account the occurrence, during the period commencing on the first of the trading
days during the twenty-trading day period and ending on the Repurchase Date, of
any event described in Section 11.06, subject to the next succeeding paragraph.

      The Company will not issue fractional shares of Common Stock in payment of
the Repurchase Price. Instead, the Company will pay cash based on the Closing
Sale Price on the trading day immediately preceding the Repurchase Date for all
fractional shares. It is understood that if a holder elects to have more than
one Security purchased, the number of shares of Common Stock shall be based on
the aggregate principal amount of Securities to be purchased.

      The Company's right to exercise its election to purchase Securities
through the issuance of shares of Common Stock shall be conditioned upon:

            (i) the Company's giving a timely Company Repurchase Notice
containing an election to purchase the Securities with shares of Common Stock as
provided herein;

            (ii) the registration of such shares of Common Stock under the
Securities Act and the Exchange Act, if required;

            (iii) the listing of such shares of Common Stock on a United States
national securities exchange or the quotation of such shares of Common Stock on
an interdealer quotation system of any registered United States national
securities association, in each case, if the Common Stock is then listed on a
national securities exchange or quoted in an inter-dealer quotation system;

            (iv) any necessary qualification or registration of such shares of
Common Stock under applicable state securities laws or the availability of an
exemption from such qualification and registration; and

                                      -21-
<PAGE>
            (v) the receipt by the Trustee of (1) an Officers' Certificate,
stating that the conditions to the issuance of the shares of Common Stock have
been satisfied and (2) an Opinion of Counsel to the effect that the shares of
Common Stock to be issued by the Company in payment of the Repurchase Price in
respect of the Securities have been duly authorized and, when issued and
delivered pursuant to the terms of this Indenture in payment of the Repurchase
Price in respect of the Securities, will be validly issued, fully paid and
non-assessable and, to the best of such counsel's knowledge, free from
preemptive rights under applicable state law or known material contracts.

      Such Officers' Certificate shall also set forth the number of shares of
Common Stock to be issued for each $1,000 principal amount of Securities and the
Closing Sale Price of a share of Common Stock on each trading day during the
period commencing on the twentieth trading day immediately preceding but ending
on the third business day prior to the applicable Repurchase Date. If the
foregoing conditions are not satisfied prior to the close of business on the
last day prior to the Repurchase Date and the Company has elected to repurchase
the Securities through the issuance of shares of Common Stock, the Company shall
pay the entire Repurchase Price of the Securities in cash.

      Promptly after determination of the actual number of shares of Common
Stock to be issued upon repurchase of Securities, the Company shall be required
to disseminate a press release through Dow Jones & Company, Inc. or Bloomberg
Business News containing this information or publish the information on the
Company's website or through such other public medium as the Company may use at
that time.

      (d) In connection with any repurchase of Securities, the Company shall, no
less than 30 business days prior to each Repurchase Date, give notice to holders
(with a copy to the Trustee) setting forth information specified in this Section
3.09(d) (the "Company Repurchase Notice").

      Each Company Repurchase Notice shall:

            (i) state the Repurchase Price and the Repurchase Date to which the
Company Repurchase Notice relates;

            (ii) state whether the Repurchase Price will be paid in cash or
shares of Common Stock;

            (iii) if shares of Common Stock will be used to pay the Repurchase
Price, state:

                  (1) the method for valuing the shares of Common Stock to be
                  delivered in connection with the repurchase; and

                  (2) that holders of the Securities will bear the market risk
                  with respect to the value of the shares of Common Stock to be
                  delivered from the date the number of shares is determined;

            (iv) include a form of Repurchase Notice;

            (v) state the Conversion Rate and Conversion Price;

            (vi) state the name and address of the Conversion Agent;

            (vii) state that Securities must be surrendered to the Paying Agent
to collect the Repurchase Price;

                                      -22-
<PAGE>
            (viii) if the Securities are then convertible, state that Securities
as to which a Repurchase Notice has been given may be converted only if the
Repurchase Notice is withdrawn in accordance with the terms of this Indenture;
and

            (ix) state the CUSIP number of the Securities.

      Company Repurchase Notices may be given by the Company or, at the
Company's request, the Trustee shall give such Company Repurchase Notice in the
Company's name and at the Company's expense.

      (e) All shares of Common Stock delivered upon repurchase of the Securities
shall be newly issued shares or treasury shares, shall be duly authorized,
validly issued, fully paid and nonassessable and shall be free from preemptive
rights and free of any lien or adverse claim created by the Company.

      (f) If a holder of a repurchased Security is paid in shares of Common
Stock, the Company shall pay any documentary, stamp or similar issue or transfer
tax due on such issue of Common Stock. However, the holder shall pay any such
tax which is due because the holder requests the Common Stock to be issued in a
name other than the holder's name. The Paying Agent may refuse to deliver the
certificates representing the shares of Common Stock being issued in a name
other than the holder's name until the Paying Agent receives a sum sufficient to
pay any tax which will be due because the shares of Common Stock are to be
issued in a name other than the holder's name. Nothing herein shall preclude any
income tax withholding required by applicable law or regulations.

      (g) The Company will comply with the provisions of Rule 13e-4 and any
other tender offer rules under the Exchange Act to the extent then applicable in
connection with the repurchase rights of the holders of Securities.

SECTION 3.10 Effect of Repurchase Notice.

      Upon receipt by the Paying Agent of the Repurchase Notice specified in
Section 3.08, the holder of the Security in respect of which such Repurchase
Notice was given shall (unless such Repurchase Notice is validly withdrawn)
thereafter be entitled to receive solely the Repurchase Price with respect to
such Security. Such Repurchase Price shall be paid to such holder, subject to
receipt of funds and/or Securities by the Paying Agent, promptly following the
later of (a) the Repurchase Date with respect to such Security (provided the
holder has satisfied the conditions in Section 3.08) and (b) the time of
delivery or book-entry transfer of such Security to the Paying Agent by the
holder thereof in the manner required by Section 3.08. Securities in respect of
which a Repurchase Notice has been given by the holder thereof may not be
converted pursuant to Article 11 hereof on or after the date of the delivery of
such Repurchase Notice unless such Repurchase Notice has first been validly
withdrawn.

      A Repurchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Paying Agent in accordance with the
Repurchase Notice at any time prior to the close of business on the Repurchase
Date, specifying:

            (i) the certificate numbers, if any, of the Security in respect of
which such notice of withdrawal is being submitted, or the appropriate
Depositary information if the Security in respect of which such notice of
withdrawal is being submitted is represented by a Global Security,

                                      -23-
<PAGE>
            (ii) the principal amount of the Security with respect to which such
notice of withdrawal is being submitted, and

            (iii) the principal amount, if any, of such Security which remains
subject to the original Repurchase Notice and which has been or will be
delivered for purchase by the Company.

      A written notice of withdrawal of a Repurchase Notice may be in the form
set forth in the preceding paragraph or may be in the form of a conditional
withdrawal contained in a Repurchase Notice pursuant to the terms of Section
3.08(a)(i)(4).

SECTION 3.11 Deposit of Repurchase Price.

      Prior to 10:00 a.m. New York City Time on the business day following the
Repurchase Date, the Company shall deposit with the Paying Agent (or, if the
Company or a Subsidiary or an Affiliate of either of them is acting as the
Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an
amount of cash (in immediately available funds if deposited on such business
day) or Common Stock, if permitted hereunder, sufficient to pay the aggregate
Repurchase Price of all the Securities or portions thereof that are to be
purchased as of the Repurchase Date.

      As soon as practicable after the Repurchase Date the Company shall deliver
to each holder of Securities entitled to receive shares of Common Stock through
the Paying Agent, a certificate for the number of full shares of Common Stock
issuable in payment of the Repurchase Price and cash in lieu of any fractional
interests. The person in whose name the certificate for the shares of Common
Stock is registered shall be treated as a holder of record of Common Stock on
the business day following the Repurchase Date. No payment or adjustment will be
made for dividends on the shares of Common Stock the record date for which
occurred on or prior to the Repurchase Date.

SECTION 3.12 Securities Repurchased in Part.

      Upon presentation of any Security repurchased only in part, the Company
shall execute and the Trustee shall authenticate and make available for delivery
to the holder thereof, at the expense of the Company, a new Security or
Securities, of any authorized denomination, in aggregate principal amount equal
to the unrepurchased portion of the Securities presented.

SECTION 3.13 Repayment to the Company.

      The Paying Agent shall return to the Company any cash or shares of Common
Stock that remain unclaimed after a period of two years, together with interest
or dividends, if any, thereon, held by it for the payment of the Repurchase
Price; provided, however, that the Company, or the Trustee at the written
request and expense of the Company, shall have first caused notice of such
payment to the Company to be mailed to each holder of Securities entitled
thereto no less than 30 days prior to such payment and all liability of the
Trustee and the Paying Agent shall thereupon cease with respect to such monies
and the holder of any of the Securities shall thereafter look only to the
Company for any payment which such holder may be entitled to collect unless an
applicable abandoned property law designates another person. To the extent that
the aggregate amount of cash or shares of Common Stock deposited by the Company
pursuant to Section 3.11 exceeds the aggregate Repurchase Price of the
Securities or portions thereof which the Company is obligated to purchase as of
the Repurchase Date, then, unless otherwise agreed in writing with the Company,
promptly after the business day following the Repurchase Date, the Paying Agent
shall return any such excess to the Company together with interest or dividends,
if any, thereon.

                                      -24-

SECTION 3.14 Redemption of Securities at Option of the Holder Upon Fundamental
Change.

      (a) If there shall occur a Fundamental Change at any time prior to the
Maturity Date, then each holder of Securities shall have the right, at such
holder's option, to require the Company to redeem all of such holder's
Securities, or any portion thereof that is a multiple of $1,000 principal
amount, on the date (the "Fundamental Change Redemption Date") that is thirty
days after the date of the Fundamental Change Notice (as defined in Section
3.14(b)) (or, if such 30th day is not a business day, the next succeeding
business day) at a redemption price (the "Fundamental Change Redemption Price")
equal to 100% of the principal amount thereof, together with accrued interest
and any Additional Amounts to, but excluding, the Fundamental Change Redemption
Date; provided that if such Fundamental Change Redemption Date is an Interest
Payment Date, then the interest payable on such Interest Payment Date shall be
paid to the holders of record of the Securities on the applicable Regular Record
Date instead of the holders surrendering the Securities for redemption on such
date.

      Upon presentation of any Security redeemed in part only, the Company shall
execute and, upon written order of the Company signed by an Officer, the Trustee
shall authenticate and make available for delivery to the holder thereof, at the
expense of the Company, a new Security or Securities, of authorized
denominations, in aggregate principal amount equal to the unredeemed portion of
the Securities presented.

      (b) On or before the tenth day after the occurrence of a Fundamental
Change, the Company or at its written request (which must be received by the
Trustee at least five business days prior to the date the Trustee is requested
to give notice as described below, unless the Trustee shall agree in writing to
a shorter period), the Trustee, in the name of and at the expense of the
Company, shall mail or cause to be mailed to all holders of record on the date
of the Fundamental Change a notice (the "Fundamental Change Notice") of the
occurrence of such Fundamental Change and of the redemption right at the option
of the holders arising as a result thereof. Such notice shall be mailed in the
manner and with the effect set forth in Section 3.03 (without regard for the
time limits set forth therein). If the Company shall give such notice, the
Company shall also deliver a copy of the Fundamental Change Notice to the
Trustee at such time as it is mailed to the holders of Securities.

      Each Fundamental Change Notice shall specify:

            (i) the circumstances constituting the Fundamental Change;

            (ii) the redemption right at the option of the holders arising as a
result of the Fundamental Change;

            (iii) the Fundamental Change Redemption Date;

            (iv) the Fundamental Change Redemption Price;

            (v) that the holder must exercise the redemption right on or prior
to the close of business on the Fundamental Change Redemption Date (the
"Fundamental Change Expiration Time");

            (vi) that the holder shall have the right to withdraw any Securities
surrendered prior to the Fundamental Change Expiration Time;

                                      -25-
<PAGE>
            (vii) a description of the procedure which a holder must follow to
exercise such redemption right and to withdraw any surrendered Securities;

            (viii) the place or places where the holder is to surrender such
holder's Securities;

            (ix) the amount of interest and any Additional Amounts accrued on
each Security to (but excluding) the Fundamental Change Redemption Date; and

            (x) the CUSIP number or numbers of the Securities.

      No failure of the Company to give the foregoing notices and no defect
therein shall limit the holders' redemption rights or affect the validity of the
proceedings for the redemption of the Securities pursuant to this Section 3.14.

      (c) For a Security, other than a Global Security, to be so redeemed at the
option of the holder, the Company must receive at the office or agency of the
Company maintained for that purpose or, at the option of such holder, the
Corporate Trust Office, a written notice electing repayment upon a Fundamental
Change stating:

            (i) the certificate number of the Security which the holder will
deliver to be purchased;

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

            (iii) that such Security shall be purchased pursuant to the terms
and conditions specified in paragraph 6 of the Securities,

together with such Securities duly endorsed for transfer, on or before the
Fundamental Change Expiration Time. All questions as to the validity,
eligibility (including time of receipt) and acceptance of any Security for
redemption shall be determined by the Company, whose determination shall be
final and binding absent manifest error.

      (d) Prior to 10:00 am, New York City Time, on the business day following
the Fundamental Change Redemption Date, the Company will deposit with the Paying
Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is
acting as Paying Agent, shall segregate and hold in trust as provided in Section
2.04) an amount of money sufficient to redeem on the Fundamental Change
Redemption Date all the Securities to be redeemed on such date at the
Fundamental Change Redemption Price; provided that, if such payment is made on
the Fundamental Change Redemption Date, it must be received by the Paying Agent
by 10:00 a.m., New York City time, on such date. Payment for Securities
surrendered for redemption (and not withdrawn) prior to the Fundamental Change
Expiration Time will be made promptly (but in no event more than five business
days) following the Fundamental Change Redemption Date by mailing checks for the
amount payable to the holders of such Securities entitled thereto as they shall
appear in the Register. The Paying Agent shall return to the Company any cash
that remains unclaimed after a period of two years, together with interest or
dividends, if any, thereon, held by it for the payment of the Fundamental Change
Redemption Price; provided, however, that the Company, or the Trustee at the
written request and expense of the Company, shall have first caused notice of
such payment to the Company to be mailed to each holder of Securities entitled
thereto no less than 30 days prior to such payment and all liability of the
Trustee and the Paying Agent shall thereupon cease with

                                      -26-
<PAGE>
respect to such monies and the holder of any of the Securities shall thereafter
look only to the Company for any payment which such holder may be entitled to
collect unless an applicable abandoned property law designates another person.
The Paying Agent shall as promptly as practicable return to the Company any
money, together with interest or dividends thereon, if any, not required for
that purpose because of conversion of Securities pursuant to Article 11. 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.

      (e) In the case of a reclassification, change, consolidation, merger,
combination, sale or conveyance to which Section 11.14 applies, in which the
Common Stock of the Company is changed or exchanged as a result into the right
to receive stock, securities or other property or assets (including cash), which
includes shares of Common Stock of the Company or shares of common stock of
another person that are, or upon issuance will be, traded on a United States
national securities exchange or approved for trading on an established automated
over-the-counter trading market in the United States and such shares constitute
at the time such change or exchange becomes effective in excess of 50% of the
aggregate fair market value of such stock, securities or other property or
assets (including cash) (as determined by the Company, which determination shall
be conclusive and binding), then the person formed by such consolidation or
resulting from such merger or which acquires such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture (accompanied
by an Opinion of Counsel that such supplemental indenture complies with the TIA
as in force at the date of execution of such supplemental indenture) modifying
the provisions of this Indenture relating to the right of holders of the
Securities to cause the Company to repurchase the Securities following a
Fundamental Change, including without limitation the applicable provisions of
this Section 3.14 and the definitions of Common Stock and Fundamental Change, as
appropriate, as determined in good faith by the Company (which determination
shall be conclusive and binding), to make such provisions apply to such other
person if different from the Company and the common stock issued by such person
(in lieu of the Company and the Common Stock of the Company).

      (f) The Company will comply with the provisions of Rule 13e-4 and any
other tender offer rules under the Exchange Act to the extent then applicable in
connection with the redemption rights of the holders of Securities in the event

Securities.

      The Company shall, and shall cause each of its subsidiaries to, pay prior
to delinquency all taxes, assessments and government levies; provided, however,
that the Company shall not be required to pay or cause to be paid any such tax,
assessment or levy (a) if the failure to do so will not, in the aggregate, have
a material adverse impact on the Company and its subsidiaries taken as a whole,
or (b) if the amount, applicability or validity is being contested in good faith
by appropriate proceedings.

SECTION 4.09 Additional Amounts Notices.

      In the event that the Company is required to pay Additional Amounts to
holders of Securities pursuant to the Registration Rights Agreement, the Company

Securities to determine the Additional Amounts, or with respect to the nature,
extent, or calculation of the amount of Additional Amounts when made, or with
respect to the method employed in such calculation of the Additional Amounts.

SECTION 6.02 Acceleration.

      If an Event of Default (other than an Event of Default with respect to the
Company specified in Sections 6.01(g) or (h)) occurs and is continuing, then and
in every such case the Trustee, by written notice to the Company, or the holders
of at least 25% in aggregate principal amount of the then outstanding
Securities, by written notice to the Company and the Trustee, may declare the
unpaid

                                      -32-
<PAGE>
principal of, premium, if any, and accrued and unpaid interest and Additional
Amounts, if any, on all the Securities to be due and payable. Upon such
declaration such principal amount, premium, if any, and accrued and unpaid
interest and Additional Amounts, if any, shall become immediately due and
payable, notwithstanding anything contained in this Indenture or the Securities
to the contrary. If any Event of Default with respect to the Company specified
in Sections 6.01(g) or (h) occurs, all unpaid principal of and premium, if any,
and accrued and unpaid interest and Additional Amounts, if any, on the
Securities then outstanding shall become automatically due and payable, without
any declaration or other act on the part of the Trustee or any holder of
Securities.

      The holders of a majority in aggregate principal amount of the Securities
then outstanding may, on behalf of the holders of all of the Securities, waive
an existing Default or Event of Default and its consequences, except a Default
or Event of Default in the payment of principal of, premium, if any, interest
and Additional Amounts, if any, on the Securities (other than the nonpayment of
principal of, premium, if any, interest and Additional Amounts, if any, on the
Securities which has become due solely by virtue of an acceleration that has
been duly rescinded as provided above) or in respect of a covenant or provision
of this Indenture that cannot be modified or amended without the consent of all
holders of the Securities. No such rescission shall affect any subsequent or
other Default or Event of Default or impair any right consequent thereto.

SECTION 6.03 Other Remedies.

      If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy by proceeding at law or in equity to collect the payment of
principal of, premium, if any, or interest or Additional Amounts, if applicable,
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 it
does not possess any of the Securities or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any holder of a Security in
exercising any right or remedy occurring upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. All remedies are cumulative to the extent permitted by law.

SECTION 6.04 Waiver of Past Defaults.

      The holders of a majority in aggregate principal amount of the Securities
then outstanding may, on behalf of the holders of all of the Securities, waive
an existing Default or Event of Default and its consequences, except a Default
or Event of Default in the payment of principal of, premium, if any, interest
and Additional Amounts, if any, on the Securities (other than the nonpayment of
principal of, premium, if any, interest and Additional Amounts, if any, on the
Securities which has become due solely by virtue of an acceleration that has
been duly rescinded as provided above) or in respect of a covenant or provision
of this Indenture that cannot be modified or amended without the consent of all
holders of the Securities. No such rescission shall affect any subsequent or
other Default or Event of Default or impair any right consequent thereto.

SECTION 6.05 Control by Majority.

      The holders of a majority in aggregate principal amount of the then
outstanding Securities may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on it. However, the Trustee may refuse to follow any direction
that conflicts with law or this Indenture that the Trustee determines may be
unduly prejudicial to the rights of other holders of Securities or that may
involve the Trustee in personal liability; provided that the

                                      -33-
<PAGE>
Trustee shall have no duty or obligation (subject to Section 7.01) to ascertain
whether or not such actions of forbearances are unduly prejudicial to such
holders; provided, further, that the Trustee may take any other action the
Trustee deems proper that is not inconsistent with such directions.

SECTION 6.06 Limitation on Suits.

      A holder of Securities may not pursue any remedy with respect to this
Indenture or the Securities unless:

            (i) the holder gives the Trustee written notice of a continuing
Event of Default;

            (ii) the holders of at least 25% in aggregate principal amount of
the then outstanding Securities make a written request to the Trustee to pursue
the remedy;

            (iii) such holder or holders offer and, if requested, provide to the
Trustee indemnity reasonably satisfactory to the Trustee against any loss,
liability or expense;

            (iv) the Trustee does not act on the request within 60 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

            (v) during such 60-day period the holders of a majority in aggregate
principal amount of the then outstanding Securities do not give the Trustee a
direction inconsistent with the request.

      A holder of Securities may not use this Indenture to prejudice the rights
of another holder or to obtain a preference or priority over another holder.

SECTION 6.07 Rights of Holders To Receive Payment.

      Notwithstanding any other provision of this Indenture, the right of any
holder of Securities to receive payment of principal of, premium, if any, and
interest and Additional Amounts, if any, on the Securities, on or after the
respective due dates expressed in the Securities, or to bring suit for the
enforcement of any such payment on or after such respective dates, or to bring
suit for the enforcement of the right to convert the Securities shall not be
impaired or affected without the consent of the holder of Securities.

SECTION 6.08 Collection Suit by Trustee.

      If an Event of Default specified in Sections 6.01(a) or (b) 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 of principal of,
premium, if any, and interest and Additional Amounts, if any, remaining unpaid
on the Securities and interest on overdue principal of, premium, if any, and
interest and Additional Amounts, if any, and such further amount as shall be
sufficient to cover the costs and, to the extent lawful, expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

SECTION 6.09 Trustee May File Proofs of Claim.

      The Trustee may file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee and the
holders of Securities allowed in any judicial proceedings relative to the
Company, its creditors or its property. Nothing contained herein shall be

                                      -34-
<PAGE>
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any holder of Securities any plan of reorganization, arrangement,
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.

      Subject to Article 12, if the Trustee collects any money pursuant to this
Article, it shall pay out the money in the following order:

            First: to the Trustee for amounts due under Section 7.07, including
            payment of all compensation, expenses and liabilities incurred, and
            all advances made, by the Trustee, and the costs and expenses of
            collection;

            Second: to holders of Securities for amounts due and unpaid on the
            Securities for principal of, premium, if any, and interest and
            Additional Amounts, if any, ratably, without preference or priority
            of any kind, according to the amounts due and payable on the
            Securities for principal of, premium, if any, and interest and
            Additional Amounts, if any, respectively; and

            Third: to the Company.

      Except as otherwise provided in Section 2.12, the Trustee may fix a record
date and payment date for any payment to holders of Securities.

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 a Trustee, a court in its discretion may require the filing by any party
litigant in the suit, other than the Trustee, 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 does not apply to a suit by
the Trustee, a suit by a holder pursuant to Section 6.07 or a suit by holders of
more than 10% in aggregate principal amount of the then outstanding Securities.

shall be subject to the provisions of this Article 7.

SECTION 7.01 Duties of the Trustee.

      (a) If an Event of Default known to a Trust Officer of the Trustee has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Indenture and use

                                      -35-

furnished to the Trustee and conforming to the requirements of this Indenture.
However, in the case of any such certificates or opinions which by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee
shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture (but need not confirm or
investigate the accuracy of mathematical calculations or other facts stated
therein).

      (c) The Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct, except

Counsel, or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, security or other document believed in good
faith by it to be genuine and to have been signed or presented by the proper

herein shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof is herein specifically prescribed). In addition,
before the Trustee acts or refrains from acting, it may require an Officers'
Certificate, an Opinion of Counsel or both. The Trustee shall not be liable for
any action it takes or omits to take in good faith in reliance on such Officers'
Certificate or Opinion of Counsel. The Trustee may consult with counsel of its
selection and the advice of such counsel or any Opinion of Counsel shall be full
and complete authorization and protection from liability in respect of any
action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon.

      (c) The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through its attorneys and
agents and other persons not regularly in its employ and shall not be
responsible for the misconduct or negligence of any attorney or agent appointed
with due care.

      (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith without negligence or willful misconduct which it believes to
be authorized or within its discretion, rights or powers.

request, direction or notice from the Company shall be sufficient if signed by

      (g) The Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request, order or direction of
any of the holders of Securities pursuant to the provisions of this Indenture,
unless such holders have offered to the Trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities which might be
incurred thereby.

      (h) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, security or other document
unless requested in writing to do so by the holders of not less than a majority
in aggregate principal amount of the Securities then outstanding, provided that
if the Trustee determines in its discretion to make any such investigation, then
it shall be entitled, upon reasonable prior notice and during normal business
hours, to examine the books and records and the premises of the Company,
personally or by agent or attorney, and the reasonable expenses of every such
examination shall be paid by the Company or, if paid by the Trustee or any
predecessor Trustee, shall be reimbursed by the Company upon demand.

      (i) The permissive rights of the Trustee to do things enumerated in this
Indenture shall not be construed as a duty, and the Trustee shall not be
answerable for other than its negligence or willful misconduct.

      (j) The Trustee shall not be responsible for the computation of any
adjustment to the Conversion Rate (or Conversion Price) or for any determination

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 7.03 Individual Rights of the Trustee.

      Subject to Sections 7.10 and 7.11, the Trustee in its individual or any
other capacity may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee and may otherwise deal with the
Company or an Affiliate of the Company and receive, collect, hold and retain
collections from the Company with the same rights it would have if it were not
Trustee. Any Agent may do the same with like rights.

SECTION 7.04 Trustee's Disclaimer.

      The Trustee shall not be responsible for and 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 of the proceeds from the Securities or any
money paid to the Company or upon the Company's direction under any provision of
this Indenture. It shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the
Securities or any other document in connection with the sale of the Securities
or pursuant to this Indenture other than its certificate of authentication.

SECTION 7.05 Notice of Defaults.

      If a Default or Event of Default occurs and is continuing and if it is
known to a Trust Officer of the Trustee, the Trustee shall mail to each holder
of Securities a notice of the Default or Event of Default within 90 days after
it occurs. A Default or an Event of Default shall not be considered known to a
Trust Officer of the Trustee unless it is a Default or Event of Default in the
payment of principal of, premium, if any, or interest and Additional Amounts, if
any, when due under Sections 6.01(a), (b) or (d) or a Trust Officer of the
Trustee shall have received notice thereof, in accordance with this Indenture,
from the Company or from the holders of a majority in aggregate principal amount
of the outstanding Securities. Except in the case of a Default or Event of
Default in payment of principal of, premium, if any, or interest or Additional
Amounts, if any, on any of the Securities, the Trustee may withhold the notice
if and so long as a committee of its Trust Officers in good faith determines
that withholding the notice is in the interest of the holders of the Securities.

SECTION 7.06 Reports by the Trustee to Holders.

      Within 60 days after the reporting date stated in Section 10.10, the
Trustee shall mail to holders of Securities a brief report dated as of such
reporting date that complies with TIA Section 313(a) (but if no event described
in TIA Section 313(a) has occurred within twelve months preceding the reporting
date, no report need

                                      -38-
<PAGE>
be transmitted). The Trustee also shall comply with TIA Section 313(b)(2). The
Trustee shall also transmit by mail all reports as required by TIA Section
313(c).

      A copy of each report at the time of its mailing to holders of Securities
shall be filed, at the expense of the Company, by the Trustee with the
Commission and each stock exchange or securities market, if any, on which the
Securities are listed or quoted. The Company shall timely notify the Trustee
when the Securities are listed or quoted on any stock exchange or securities
market or of any delisting thereof.

SECTION 7.07 Compensation and Indemnity.

      The Company shall pay to the Trustee from time to time, and the Trustee
shall be entitled to, such compensation for its acceptance of this Indenture and
its services hereunder as the Company and the Trustee shall from time to time
agree in writing. The Trustee's compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Company shall reimburse the
Trustee promptly upon request for all reasonable disbursements, advances and
expenses incurred or made by or on behalf of it in addition to the compensation
for its services. Such expenses may include the reasonable compensation,
disbursements and expenses of the Trustee's agents, counsel and other persons
not regularly in its employ.

      The Company shall indemnify each of the Trustee and any predecessor
Trustee against, and defend and hold each of them harmless from, any and all
loss, liability or expense incurred by it arising out of or in connection with
the acceptance or administration of its duties under this Indenture and the
trusts hereunder, including the costs and expenses of defending itself against
or investigating any claim (regardless of whether asserted by the Company, a
holder or any other person) of liability in the premises, except as set forth in
the next paragraph. The Trustee shall notify the Company promptly of any claim
for which it may seek indemnity. Failure by the Trustee to so notify the Company
shall not relieve the Company of its obligations hereunder. The Company shall
defend the claim with counsel designated by the Company, who may be outside
counsel to the Company but shall in all events be reasonably satisfactory to the
Trustee, and the Trustee shall cooperate in the defense. In addition, the
Trustee may retain one separate counsel and, if deemed advisable by such
counsel, local counsel, and the Company shall pay the reasonable fees and
expenses of such separate counsel and local counsel. The indemnification herein
extends to any settlement, provided that the Company will not be liable for any
settlement made without its consent, provided, further, that such consent will
not be unreasonably withheld.

      The Company need not reimburse any expense or indemnify against any loss
or liability incurred by the Trustee through its own negligence or willful
misconduct.

      The Trustee shall have a lien prior to the Securities on all money or
property held or collected by the Trustee to secure the Company's payment
obligations in this Section 7.07, except that held in trust to pay principal of,
premium, if any, and interest and Additional Amounts, if any, on the Securities.
Such liens and the Company's obligations under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture.

      When the Trustee incurs expenses or renders services after an Event of
Default specified in Sections 6.01(g) or (h) occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

SECTION 7.08 Replacement of the Trustee.

      A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.08.

      The Trustee may resign at any time and be discharged from the trust hereby
created by so notifying the Company. The holders of a majority in aggregate
principal amount of the then outstanding Securities may remove the Trustee by so
notifying the Trustee and the Company in writing. The Company may remove the
Trustee if:

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

            (ii) the Trustee is adjudged a bankrupt or an insolvent or an order
for relief is entered with respect to the Trustee under any Bankruptcy Law;

            (iii) a custodian under any Bankruptcy Law or public officer takes
charge of the Trustee or its property; or

            (iv) the Trustee becomes incapable of acting.

      If the Trustee resigns, is removed, becomes incapable of acting or if a
vacancy exists in the office of Trustee for any reason, the Company shall
promptly appoint a successor Trustee. Within one year after the successor
Trustee takes office, the holders of a majority in aggregate principal amount of
the then outstanding Securities may appoint a successor Trustee to replace the
successor Trustee appointed by the Company.

      If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, at the Company's
expense, the Company or the holders of at least 10% in aggregate principal
amount of the then outstanding Securities may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

      If the Trustee after written request by any holder of Securities who has
been a holder for at least six months fails to comply with Section 7.10, such
holder may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

      A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to 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
holders of Securities. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, provided that all sums owing to
the retiring Trustee hereunder have been paid and subject to the lien provided
for in Section 7.07. Notwithstanding the replacement of the Trustee pursuant to
this Section 7.08, the Company's obligations under Section 7.07 shall continue
for the benefit of the retiring Trustee with respect to expenses and liabilities
incurred by it prior to such replacement.

      Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in the
preceding paragraph.

                                      -40-

SECTION 7.09 Successor Trustee by Merger, etc.

      If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all of its corporate trust business (including the trust
created by this Indenture) to, another corporation or national banking
association, the resulting, surviving or transferee corporation or national
banking association without any further act shall be the successor Trustee with
the same effect as if the successor Trustee had been named as the Trustee
herein.

SECTION 7.10 Eligibility, Disqualification.

      This Indenture shall always have a Trustee who satisfies the requirements
of TIA Section 310(a)(1). The Trustee shall always have a combined capital and
surplus as stated in Section 10.10. The Trustee is subject to TIA Section 310(b)
regarding the disqualification of a trustee upon acquiring a conflicting
interest.

SECTION 7.11 Preferential Collection of Claims Against Company.

      The Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship set forth 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.

SECTION 8.01 Discharge of Indenture.

      When (a) the Company delivers to the Trustee for cancellation all
Securities theretofore authenticated (other than Securities replaced pursuant to

theretofore canceled or delivered to the Trustee for cancellation have become
due and payable, or are by their terms will become due and payable within one
year or are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption, and the
Company deposits with the Trustee, in trust, the Paying Agent (if the Paying

to Section 2.07) not theretofore canceled or delivered to the Trustee for
cancellation, including principal of, premium, if any, interest and Additional
Amounts, if any, due or to become due to such date of maturity or redemption, as
the case may be, and if in either case the Company also pays, or causes to be
paid, all other sums payable hereunder by the Company, then this Indenture shall
cease to be of further effect (except as to (i) rights of registration of
transfer, substitution, replacement and exchange and conversion of Securities,
(ii) rights hereunder of holders of Securities to receive payments of principal
of, premium, if any, and interest, and Additional Amounts, if any, on, the
Securities and to receive shares of Common Stock upon conversion of the
Securities, (iii) the obligations under Sections 2.03 and 8.05 hereof and (iv)
the rights, obligations and immunities of the Trustee hereunder), and the
Trustee, on written demand of the Company accompanied by an Officers'
Certificate and an Opinion of Counsel as required by Section 10.04 and at the
Company's cost and expense, shall execute proper instruments acknowledging
satisfaction of and discharging this Indenture; the Company, however, hereby
agrees to reimburse the Trustee for any costs or expenses thereafter reasonably
and properly incurred by the Trustee and to

                                      -41-
<PAGE>
compensate the Trustee for any services thereafter reasonably and properly
rendered by the Trustee in connection with this Indenture or the Securities.

SECTION 8.02 Deposited Monies to be Held in Trust by Trustee.

      Subject to Section 8.04, all monies deposited with the Trustee pursuant to
Section 8.01 shall be held in trust and applied by it to the payment either
directly or through the Paying Agent, to the holders of the particular
Securities for the payment or redemption of which such monies have been
deposited with the Trustee, of all sums due and to become due thereon for
principal of, premium, if any, interest, and Additional Amounts, if any.

SECTION 8.03 Paying Agent to Repay Monies Held.

      Upon the satisfaction and discharge of this Indenture, all monies then
held by any Paying Agent (other than monies held by the Trustee not pursuant to
Section 8.01) shall, upon the Company's written demand, be repaid to it or paid
to the Trustee, and thereupon such Paying Agent shall be released from all
further liability with respect to such monies.

SECTION 8.04 Return of Unclaimed Monies.

      Subject to the requirements of applicable law, any monies deposited with
or paid to the Trustee for payment of the principal of, premium, if any,
interest or Additional Amounts, if any, on the Securities and not applied but
remaining unclaimed by the holders thereof for two years after the date upon
which the principal of, premium, if any, interest or Additional Amounts, if any,
on such Securities, as the case may be, have become due and payable, shall be
repaid to the Company by the Trustee on written demand; provided, however, that
the Company, or the Trustee at the written request and expense of the Company,
shall have first caused notice of such payment to the Company to be mailed to
each holder of Securities entitled thereto no less than 30 days prior to such
payment and all liability of the Trustee shall thereupon cease with respect to
such monies; and the holder of any of the Securities shall thereafter look only
to the Company for any payment which such holder may be entitled to collect
unless an applicable abandoned property law designates another person.

SECTION 8.05 Reinstatement.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 8.02 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Securities
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.01 until such time as the Trustee or the Paying Agent is permitted to
apply all such money in accordance with Section 8.02; provided, however, that if
the Company makes any payment of interest or Additional Amounts, if any, on or
principal of any Security following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the holders thereof to receive such
payment from the money held by the Trustee or Paying Agent.

SECTION 9.02 With the Consent of Holders.

      Subject to Section 6.07, the Company and the Trustee may amend this
Indenture or the Securities with the written consent of the holders of at least
a majority in aggregate principal amount of the then outstanding Securities
(including consents obtained in connection with a tender offer or exchange offer
for Securities).

                                     -43-
<PAGE>
      Subject to Sections 6.04 and 6.07, the holders of a majority in aggregate

in connection with a tender offer or exchange offer for Securities) may also
waive compliance in a particular instance by the Company with any provision of
this Indenture or the Securities.

      However, without the consent of each holder of Securities affected, an
amendment or waiver under this Section may not (with respect to any Securities
held by a non-consenting holder):

            (i) reduce the principal amount of Securities whose holders must
consent to an amendment, supplement or waiver;

            (ii) reduce the principal of, or premium on, or change the fixed

            (vi) make the principal of, or premium, if any, or interest or

      To secure a consent of the holders of Securities under this Section, it
shall not be necessary for such holders to approve the particular form of any

                                     -44-

SECTION 9.03 Compliance with the Trust Indenture Act.

      Every amendment to this Indenture or the Securities shall be set forth in
a supplemental indenture that complies with the TIA as then in effect.

SECTION 9.04 Revocation and Effect of Consents.

      Until an amendment or waiver becomes effective, a consent to it by a
holder of Securities is a continuing consent by the holder and every subsequent
holder of Securities or portion of Securities that evidences the same debt as
the consenting holder's Security, even if notation of the consent is not made on
any Security. However, any such holder or subsequent holder may revoke the
consent as to his or her Security or portion of Securities if the Trustee
receives the notice of revocation before the date on which the Trustee receives
an Officers' Certificate certifying that the holders of the requisite principal
amount of Securities have consented to the amendment or waiver.

      The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the holders of Securities entitled to consent to any
amendment or waiver. If a record date is fixed, then notwithstanding the
provisions of the immediately preceding paragraph, those persons who were
holders of Securities at such record date (or their duly designated proxies),
and only those persons, shall be entitled to consent to such amendment or waiver
or to revoke any consent previously given, whether or not such persons continue
to be holders after such record date. No consent shall be valid or effective for
more than 90 days after such record date unless consents extending such period
shall have also have been given by holders of the principal amount of Securities
required hereunder for such amendment or waiver and not revoked within such
90-day period.

      After an amendment or waiver becomes effective it shall bind every holder
of Securities, unless it is of the type described in clauses (i) through (x) of
Section 9.02. In such case, the amendment or waiver shall bind each holder of
Securities who has consented to it and every subsequent holder of Securities or
portion of Securities that evidences the same debt as the consenting holder's
Security.

SECTION 9.05      Notation on or Exchange of Securities.

      Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article 9 may, and shall if required by
the Trustee, bear a notation in the 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
Company and the Trustee, 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 without charge to the holders of the
Securities, except as specified in Section 2.06.

SECTION 9.06 Trustee Protected.

      The Trustee shall sign any amendment or supplemental indenture authorized
pursuant to this Article 9 if such amendment or supplemental indenture does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If such amendment or supplemental indenture does adversely affect the rights,
duties, liabilities or immunities of the Trustee, the Trustee may, but need not,
sign it. In signing such amendment or supplemental indenture, the Trustee shall
receive, and shall be fully protected in relying upon, an Officers' Certificate
and an Opinion of Counsel as conclusive evidence that such amendment or
supplemental indenture is authorized or permitted by this Indenture, that it is
not

                                     -45-
<PAGE>
inconsistent herewith, and that it will be valid and binding upon the Company in
accordance with its terms.

                               GENERAL PROVISIONS

SECTION 10.01 Trust Indenture Act Controls.

      If any provision of this Indenture limits, qualifies or conflicts with the
duties imposed by TIA Section 318(c), such duties imposed by such section of the
TIA shall control. If any provision of this Indenture expressly modifies or

release are part of the consideration for the Securities. Each of such

                                   ARTICLE 11

                                   CONVERSION

SECTION 11.01 Conversion Right.

      Subject to and upon compliance with the provisions of this Indenture, each
holder of Securities shall have the right, at his or her option, at any time on
or before the close of business on the last trading day prior to the Maturity
Date (subject to the next paragraph), to convert the principal amount of any
Security held by such holder, or any portion of such principal amount which is
$1,000 or an integral multiple thereof, into that number of fully paid and
non-assessable shares of Common Stock (as such shares shall then be constituted)
obtained by multiplying (i) the principal amount of the Securities or portion
thereof to be converted by (ii) a conversion rate of 64.6998 shares per $1,000
principal amount of Securities (as adjusted from time to time as provided in
this Article, the "Conversion Rate"). The initial Conversion Rate is equivalent
to a conversion price of $15.456 per share (the "Conversion Price").

      Notwithstanding the foregoing paragraph, the holders' right to conversion
will terminate: (a) with respect to any Security or portion thereof which is
called for redemption prior to the last trading day prior to the Maturity Date,
on the close of business on the last trading day preceding the Redemption Date
(unless the Company defaults in payment of the redemption price in which case
the conversion right will terminate at the close of business on the date such
default is cured) and (b) with respect to any Security or portion thereof
subject to a duly completed election for repurchase, on the close of business on
the 30th day after the date of the Fundamental Change Notice (unless the Company
defaults in the payment due upon repurchase or such holder elects to withdraw
the submission of such election to repurchase in accordance with Section 3.14).

      A holder of Securities is not entitled to any rights of a holder of Common
Stock until such holder of Securities has converted his or her Securities to
Common Stock, and only to the extent such Securities are deemed to have been
converted to Common Stock under this Article 11.

SECTION 11.02 Conversion Procedure.

      To convert a Security, a holder must satisfy the requirements in paragraph
15 of the Securities. The date on which the holder satisfies all those
requirements is the conversion date (the "Conversion Date"). Following the
Conversion Date, the Company shall deliver to the holder through the Conversion
Agent, in accordance with Section 11.20, a certificate for the number of full
shares of Common Stock issuable upon the conversion (or, at the option of the
Company, cash in lieu thereof) and cash in lieu of any fractional share
determined pursuant to Section 11.03. The Company shall determine such full
number of shares and the amounts of the required cash with respect to any
fractional share, and shall set forth such information in an Officers'
Certificate delivered to the Conversion Agent. The Conversion Agent shall have
no duties under this paragraph unless and until it has received such
certificate.

      The person in whose name the certificate is registered shall be treated as
a stockholder of record on and after the Conversion Date; provided, however,
that no surrender of a Security on any date when the stock transfer books of the
Company shall be closed shall be effective to constitute the person or persons
entitled to receive the shares of Common Stock upon such conversion as the
record holder or holders of such shares of Common Stock on such date, but such
surrender shall be effective to constitute the person or persons entitled to
receive such shares of Common Stock as the record holder or holders thereof for
all purposes at the close of business on the next succeeding day on which such
stock transfer

                                      -50-
<PAGE>
books are open; such conversion shall be at the Conversion Rate in effect on the
date that such Security shall have been surrendered for conversion, as if the
stock transfer books of the Company had not been closed. Upon conversion of a
Security, such person shall no longer be a holder of such Security.

      Holders may surrender a Security for conversion by means of book-entry
delivery in accordance with the regulations of the applicable book-entry
facility.

      Except as described in the proceeding sentence, no payment or adjustment
will be made upon conversion of any Securities for interest or Additional
Amounts, if any, accrued on such Securities or for dividends on, or other
distributions with respect to, any Common Stock issued. If Securities not called
for redemption are converted during the period from the close of business on the
Regular Record Date immediately preceding any Interest Payment Date through the
close of business on the last trading day immediately preceding such Interest
Payment Date, such Securities must be accompanied by payment, in funds
acceptable to the Company, of an amount equal to the interest and Additional
Amounts, if any, otherwise payable on such Interest Payment Date on the
principal amount of the Security then being converted.

      On conversion of a Security into shares of Common Stock, the accrued and
unpaid interest and Additional Amounts, if any, attributable to the period from
the Issue Date of the Security through the Conversion Date, with respect to the
converted Security shall not be cancelled, extinguished or forfeited, but rather
shall be deemed to be paid in full to the holder thereof through delivery of the
Common Stock (together with the cash payment, if any, in lieu of fractional
shares) in exchange for the Security being converted pursuant to the provisions
hereof; and the fair market value of such shares of Common Stock (together with
any such cash payment in lieu of fractional shares) shall be treated as issued,
to the extent thereof, first in exchange for the accrued cash interest and any
Additional Amounts through the Conversion Date, and the balance, if any, of such
fair market value of such Common Stock (and any such cash payment) shall be
treated as issued in exchange for the Issue Price of the Security being
converted pursuant to the provisions hereof. Notwithstanding the foregoing,
accrued cash interest and any Additional Amounts will be payable upon conversion
of Securities made concurrently with or after acceleration of Securities
following an Event of Default.

      If the holder converts more than one Security at the same time, the number
of shares of Common Stock issuable upon conversion shall be based on the
aggregate principal amount of the Securities converted.

      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 11.03 Fractional Shares.

      The Company will not issue a fractional share of Common Stock upon
conversion of a Security. Instead, the Company will deliver cash for the current
market value of the fractional share. The current market value of a fractional
share shall be determined, to the nearest 1/1,000th of a share, by multiplying
the Closing Sale Price of the Common Stock, on the trading day immediately
preceding the Conversion Date, by the fractional amount and rounding the product
to the nearest whole cent.

                                      -51-
<PAGE>
SECTION 11.04 Taxes on Conversion.

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

SECTION 11.05 Company to Provide Stock.

      The Company shall, prior to issuance of any Securities under this Article
11, and from time to time as may be necessary, reserve out of its authorized
Common Stock that is not outstanding a sufficient number of shares of Common
Stock to permit the conversion of the Securities.

      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 created by the Company.

SECTION 11.06 Adjustment for Change in Capital Stock.

      Except as set forth in Section 11.14, if, after the Issue Date of the
Securities, the Company:

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

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

      (c) pays a dividend or makes a distribution on its Common Stock in shares
of its Capital Stock (other than Common Stock or rights, warrants or options for
its Capital Stock);

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

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

then the conversion privilege and the Conversion Rate (and, simultaneously, the
Conversion Price) 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 or other units of Capital Stock of the Company which such holder would
have owned immediately following such action if such holder had converted the
Security immediately prior to such action.

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

                                      -52-
<PAGE>

SECTION 11.07 Adjustment for Rights Issue.

         Except as set forth in Sections 11.14 and 11.19, if, after the Issue
Date, the Company distributes any rights, warrants or options to all holders of
its Common Stock entitling them, for a period expiring within 60 days after the
record date for such distribution, to purchase shares of Common Stock at a price
per share less than the Closing Sale Price of the Common Stock as of the Time of
Determination, the Conversion Rate (and, simultaneously, the Conversion Price)
shall be adjusted in accordance with the formula:

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

         R' = the adjusted Conversion Rate.

         R = the current Conversion Rate.

         O = the number of shares of Common Stock outstanding on the record date
for the distribution to which this Section 11.07 is being applied.

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

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

         M = the Average Sale Price, minus, in the case of (i) a distribution to
which Section 11.06(c) applies or (ii) a distribution to which Section 11.08
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 11.07 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 11.07 applies, the fair
market value (on the record date for the distribution to which this Section
11.07 applies) of:

                  (i) the Capital Stock of the Company distributed in respect of
each share of Common Stock in such Section 11.06(c) distribution; and

                  (ii) the assets of the Company or debt securities or any
rights, warrants or options to purchase securities of the Company distributed in
respect of each share of Common Stock in such Section 11.08 distribution.

         The Board of Directors shall determine fair market values for the
purposes of this Section 11.07.

         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 11.07 applies. If all of the shares of Common
Stock subject to such rights, warrants or options have not been issued when such
rights, warrants or options expire, then the Conversion Rate (and,
simultaneously, the Conversion Price) shall promptly be readjusted to the
Conversion Rate (or Conversion Price) 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.

                                      -53-
<PAGE>
         No adjustment shall be made under this Section 11.07 if the application
of the formula stated above in this Section 11.07 would result in a value of R'
that is equal to or less than the value of R.

SECTION 11.08 Adjustment for Other Distributions.

         (a) Subject to Section 11.08(b), if, after the Issue Date of the
Securities, the Company distributes to all holders of its Common Stock any of
its assets excluding distributions of Capital Stock or equity interests referred
to in Section 11.08(b), or evidence of indebtedness 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 11.06 and
distributions of rights, warrants or options referred to in Section 11.07 and
(y) cash dividends or other cash distributions that are paid out of consolidated
current net earnings or earnings retained in the business as shown on the books
of the Company unless such cash dividends or other cash distributions are
Extraordinary Cash Dividends), the Conversion Rate (and, simultaneously, the
Conversion Price) shall be adjusted, subject to the provisions of Section
11.08(d), in accordance with the formula:

                            R' =    R x M
                                 ------------
                                    M - F
         where:

         R' = the adjusted Conversion Rate.

         R = the current Conversion Rate.

         M = the Average Sale Price, minus, in the case of a distribution to
which Section 11.06(c) applies, for which (i) the record date shall occur on or
before the record date for the distribution to which this Section 11.08 applies
and (ii) the Ex-Dividend Time shall occur on or after the date of the Time of
Determination for the distribution to which this Section 11.08 applies, the fair
market value (on the record date for the distribution to which such Section
11.06(c) applies) of any Capital Stock of the Company distributed in respect of
each share of Common Stock in such Section 11.06(c) distribution.

         F = the fair market value (on the record date for the distribution to
which this Section 11.08 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 11.08 is being applied (including, in the
case of cash dividends or other cash distributions giving rise to an adjustment,
all such cash distributed concurrently).

         The Board of Directors shall determine fair market values for the
purposes of this Section 11.08.

         The adjustment shall become effective immediately after the record date
for the determination of shareholders entitled to receive the distribution to
which this Section 11.08 applies.

         For purposes of this Section 11.08, the term "Extraordinary Cash
Dividend" shall mean any cash dividend or distribution with respect to the
Common Stock the amount of which, together with the aggregate amount of cash
dividends on the Common Stock to be aggregated with such cash dividend in
accordance with the provisions of this paragraph, exceeds the threshold
percentage set forth in item (i) below. For purposes of item (i) below, the
"Ex-Dividend Measurement Period" with respect to a cash dividend on the Common
Stock shall mean the 365 consecutive day period ending on the date prior to the
Ex-Dividend Time with respect to such cash dividend, and the "Relevant Cash
Dividends" with respect to

                                      -54-
<PAGE>
a cash dividend on the Common Stock shall mean the cash dividends on the Common
Stock with Ex-Dividend Times occurring in the Ex-Dividend Measurement Period.

(i) If, upon the date prior to the Ex-Dividend Time with respect to a cash
dividend on the Common Stock, the aggregate amount of such cash dividend
together with the amounts of all Relevant Cash Dividends exceeds on a per share
basis 5% of the Closing Sale Price of the Common Stock on the last trading day
preceding the date of declaration by the Board of Directors of the cash dividend
or distribution with respect to which this provision is being applied, then such
cash dividend together with all Relevant Cash Dividends, shall be deemed to be
an Extraordinary Cash Dividend and for purposes of applying the formula set
forth above in this Section 11.08, the value of "F" shall be equal to (y) the
aggregate amount of such cash dividend together with the amount of all Relevant
Cash Dividends, minus (z) the aggregate amount of all Relevant Cash Dividends
for which a prior adjustment in the Conversion Rate (and Conversion Price) was
previously made under this Section 11.08.

         In making the determinations required by item (i) above, the amount of
cash dividends paid on a per share basis and the amount of any Relevant Cash
Dividends specified in item (i) above, shall be appropriately adjusted to
reflect the occurrence during such period of any event described in Section
11.06.

         (b) If, after the Issue Date of the Securities, the Company pays a
dividend or makes a distribution to all holders of its Common Stock consisting
of Capital Stock of any class or series, or similar equity interests, of or
relating to a Subsidiary or other business unit of the Company, the Conversion
Rate (and, simultaneously, the Conversion Price) shall be adjusted in accordance
with the formula:

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

where:

         R' = the adjusted Conversion Rate.

         R = the current Conversion Rate.

         M = the average of the Closing Sale Prices of the Common Stock for the
ten trading days commencing on and including the fifth trading day after the
date on which "exdividend trading" commences for such dividend or distribution
on The Nasdaq National Market or such other national or regional exchange or
market which such securities are then listed or quoted (the "Ex-Dividend Date").

         F = the fair market value of the securities distributed in respect of
each share of Common Stock for which this Section 11.08(b) applies shall mean
the number of securities distributed in respect of each share of Common Stock
multiplied by the average of the Closing Sale Prices of those securities
distributed for the ten (10) trading days commencing on and including the fifth
trading day after the Ex-Dividend Date.

         (c) In the event that, with respect to any distribution to which
Section 11.08(a) would otherwise apply, the difference between "M-F" as defined
in the formula set forth in Section 11.08(a) is less than $1.00 or "F" is equal
to or greater than "M", then the adjustment provided by Section 11.08(a) shall
not be made and in lieu thereof the provisions of Section 11.14 shall apply to
such distribution.

SECTION 11.09 When Adjustment May Be Deferred.

         No adjustment in the Conversion Rate (or Conversion Price) need be made
unless the adjustment would require an increase or decrease of at least 1% in
the Conversion Rate (or Conversion Price). Any adjustments that are not made
shall be carried forward and taken into account in any subsequent adjustment and
all adjustments that are made and carried forward shall be taken in the
aggregate in order to determine if the 1% threshold is met.

         All calculations under this Article 11 shall be made to the nearest
cent or to the nearest 1/1,000th of a share, as the case may be.

SECTION 11.10 When No Adjustment Required.

         No adjustment in the Conversion Rate (or Conversion Price) need be made
for a transaction referred to in Sections 11.06, 11.07, 11.08 or 11.14 if
holders of Securities are to participate in the transaction on a basis and with
notice that the Board of Directors determines to be fair and appropriate in
light of the basis and notice on which holders of Common Stock participate in
the transaction. Such participation by holders of Securities may include
participation upon conversion provided that an adjustment shall be made at such
time as the holders of Securities are no longer entitled to participate.

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

         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 11 into cash, no adjustment need be made thereafter as to the cash.
Interest will not accrue on the cash.

         No adjustment will be made pursuant to this Article 11 that would
result, through the application of one or more provisions hereof, in the
duplication of any adjustment.

         Except as expressly provided in this Article 11, no adjustment shall be
made in respect of any issuance of Common Stock, or any securities convertible
into or exercisable or exchangeable for Common Stock or carrying the right to
purchase any of the foregoing.

SECTION 11.11 Notice of Adjustment.

         Whenever the Conversion Rate (or Conversion Price) is adjusted, the
Company shall promptly mail to holders of Securities a notice of the adjustment.
The Company shall file with the Trustee and the Conversion Agent such notice, an
Officers' Certificate and a certificate from the Company's independent public
accountants briefly stating the facts requiring the adjustment and the manner of
computing it. Upon receipt by it of such notice, and at the written request of
the Company, the Conversion Agent will promptly mail such notice to holders of
Securities at the Company's expense. 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.

                                      -56-
<PAGE>
SECTION 11.12 Voluntary Increase.

         The Company from time to time may voluntarily increase the Conversion
Rate (and, simultaneously, reduce the Conversion Price) by any amount for any
period of at least 20 days, in which case the Company shall give at least 15
days' notice of such decrease, if the Board of Directors has made a
determination that such decrease would be in the Company's best interests, which
determination shall be conclusive. Whenever the Conversion Rate (or Conversion
Price) is increased, the Company shall mail to holders of Securities 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 (and reduced Conversion Price) takes effect. The notice shall state the
increased Conversion Rate (and reduced Conversion Price) and the period it will
be in effect.

         A voluntary increase of the Conversion Rate (and reduced Conversion
Price) does not change or adjust the Conversion Rate (or Conversion Price)
otherwise in effect for purposes of Sections 11.06, 11.07, 11.08 or 11.14.

SECTION 11.13 Notice of Certain Transactions.

         If:

         (a) the Company takes any action that would require an adjustment in
the Conversion Rate (and Conversion Price) pursuant to Sections 11.06, 11.07 or
11.08 (unless no adjustment is to occur pursuant to Section 11.10); or

         (b) the Company takes any action that would require a supplemental
indenture pursuant to Section 11.14; or

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

then the Company shall mail to holders of Securities and file with the Trustee
and the Conversion Agent a notice stating the proposed record date for a
dividend or distribution or the proposed effective date of a subdivision,
combination, reclassification, consolidation, merger, binding share exchange,
transfer, liquidation or dissolution. The Company shall file and mail the notice
at least 20 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 11.14 Reorganization of Company; Special Distributions.

         If the Company is a party to a transaction subject to Article 5 (other
than a sale, assignment, transfer, lease, conveyance or other disposition of all
or substantially all of the assets of the Company in a transaction in which the
holders of Common Stock immediately prior to such transaction do not receive
securities, cash, property or other assets of the Company or any other person)
which reclassifies or changes its outstanding 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 only into the kind and amount of securities, cash or other assets
which such holder would have received immediately after the consolidation,
merger, share exchange, sale, assignment, transfer, lease, conveyance

                                      -57-
<PAGE>
or other disposition 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 11. The successor Company shall mail to holders of Securities a notice
briefly describing the supplemental indenture.

         If this Section applies, none of Sections 11.06, 11.07 or 11.08 shall
apply.

         If the Company makes a distribution to all holders of its Common Stock
of any of its assets, or debt securities or any rights, warrants or options to
purchase securities of the Company that would otherwise (but does not) result in
an adjustment in the Conversion Rate (or Conversion Price) pursuant to the
provisions of Section 11.08, then, from and after the record date for
determining the holders 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 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 Common Stock entitled to receive the distribution.

SECTION 11.15 Company Determination Final.

         Any determination that the Company or the Board of Directors has the
authority to make pursuant to this Article 11 is conclusive on the Trustee,
Conversion Agent, all holders of Securities and all other interested parties;
provided that such determination has been made in good faith.

SECTION 11.16 Trustee's Adjustment Disclaimer.

         The Trustee has no duty to determine when an adjustment under this
Article 11 should be made, how it should be made or what it should be. The
Trustee has no duty to determine whether a supplemental indenture under Section
11.14 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 11. Each Conversion Agent (other
than the Company or an Affiliate of the Company) shall have the same protection
under this Section 11.16 as the Trustee.

SECTION 11.17 Simultaneous Adjustments.

         In the event that this Article 11 requires adjustments to the
Conversion Rate (or Conversion Price) under more than one of Sections 11.06,
11.07 or 11.08, 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 11.06, second, the provisions of
Section 11.08 and, third, the provisions of Section 11.07.

                                      -58-
<PAGE>
SECTION 11.18 Successive Adjustments.

         After an adjustment to the Conversion Rate (or Conversion Price) under
this Article 11, any subsequent event requiring an adjustment under this Article
11 shall cause an adjustment to the Conversion Rate (or Conversion Price) as so
adjusted.

SECTION 11.19 Rights Issued in Respect of Common Stock Issued Upon Conversion.

         Each share of Common Stock issued upon conversion of Securities
pursuant to this Article 11 shall be entitled to receive the appropriate number
of common stock or preferred stock purchase rights, as the case may be (the
"Rights"), if any, that all shares of Common Stock are entitled to receive in
accordance with any rights agreement that may be in effect at the time of such
issuance (a "Rights Agreement ") and the certificates representing the Common
Stock issued upon such conversion shall bear such legends, if any, in each case
as may be provided by the terms of any such Rights Agreement. Provided that such
Rights Agreement requires that each share of Common Stock issued by the Company
(including those that might be issued upon conversion of Securities) at any time
prior to the distribution of separate certificates representing the Rights be
entitled to receive such Rights, then, notwithstanding anything else to the
contrary in this Article 11, there shall not be any adjustment to the conversion
privilege or Conversion Rate (or Conversion Price) or any other term or
provision of the Securities as a result of the issuance of Rights, the
distribution of separate certificates representing the Rights, the exercise or
redemption of such Rights in accordance with any such Rights Agreement, or the
termination or invalidation of such Rights. Notwithstanding anything to the
contrary herein, nothing in this provision is intended to confer on the Common
Stock issuable upon conversion of Securities any right that is different than
the rights to which all shares of Common Stock of the Company are entitled to
receive.

SECTION 11.20 Company's Right to Elect to Pay Cash or Common Stock.

         In lieu of delivery of Common Stock otherwise deliverable upon notice
of conversion of any Securities, the Company may elect to pay holders
surrendering Securities an amount in cash equal to (for each share of Common
Stock otherwise so deliverable) the average of the Closing Sale Prices of Common
Stock for the five consecutive trading days immediately following either (a) the
date of notice of election to deliver cash as described below if the Company has
not given notice of redemption, or (b) the Conversion Date, in the case of
conversion following the notice of redemption specifying that the Company
intends to deliver cash upon conversion. The Company will inform the holders
through the Trustee no later than two business days following the conversion
date of its election to deliver shares of Common Stock or to pay cash in lieu of
delivery of Common Stock, unless the Company has already informed holders of its
election in connection with its optional redemption of the Securities pursuant
to Section 3.01. If the Company elects to deliver all of such payment in Common
Stock, the Common Stock will be delivered through the Conversion Agent no later
than the fifth business day following the Conversion Date. If the Company elects
to pay all or a portion of such payment in cash, the payment, including any
delivery of Common Stock, will be made to holders surrendering Securities no
later than the tenth business day following the applicable conversion date. If
an Event of Default (other than a default in a cash payment upon conversion of
the Securities) has occurred and is continuing, the Company may not pay cash
upon conversion of any Security or portion of a Security (other than cash for
fractional shares).

                                  SUBORDINATION

SECTION 12.01 Securities Subordinate to Senior Indebtedness.

         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 8), the payment of the principal of, premium, if any, interest and
Additional Amounts, if any, on each and all of the Securities are hereby
expressly made subordinate and subject in right of payment to the prior payment
in full, in cash or other form of payment satisfactory to holders, of all Senior
Indebtedness.

SECTION 12.02 Payment Over of Proceeds Upon Dissolution, Etc.

         In the event of (a) any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Company or to its creditors,
as such, or to its assets, or (b) any liquidation, dissolution or other winding
up of the Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshalling of assets and liabilities of the Company, then and in any
such event specified in clause (a), (b) or (c) above (each such event, if any,
herein sometimes referred to as a "Proceeding") the holders of Senior
Indebtedness shall be entitled to receive payment in full of all amounts due or
to become due on or in respect of all Senior Indebtedness, or provision shall be
made for such payment in cash or cash equivalents or otherwise in a manner
satisfactory to the holders of Senior Indebtedness, before the holders of the
Securities are entitled to receive any payment or distribution of any kind or
character, whether in cash, property or securities, on account of principal of,
premium, if any, interest or Additional Amounts, if any, on or other obligations
in respect of the Securities or other Indebtedness of the Company that is pari
passu or subordinate in right of payment to the Securities or on account of any
purchase or other acquisition of Securities or such other Indebtedness by the
Company or any Subsidiary of the Company (all such payments, distributions,
purchases and acquisitions herein referred to, individually and collectively, as
a "Securities Payment"), and to that end the holders of Senior Indebtedness
shall be entitled to receive, for application to the payment thereof, any
Securities Payment which may be payable or deliverable in respect of the
Securities in any such Proceeding.

         In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the holder of any Security shall have received any
Securities Payment before all Senior Indebtedness is paid in full or payment
thereof has been provided for in cash or cash equivalents or otherwise in a
manner satisfactory to the holders of Senior Indebtedness, and if such fact
shall, at or prior to the time of such Securities Payment, have been made known
to the Trustee by delivery to the Trustee of any notice set forth in Section
12.09 or, as the case may be, such holder, then and in such event such
Securities Payment shall be paid over or delivered forthwith by the Trustee (if
any notice set forth in Section 12.09 has been delivered to the Trustee) or by
the holder to the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee, agent or other person making payment or distribution of
assets of the Company (which may be the Administrative Agent) for application to
the payment of all Senior Indebtedness remaining unpaid, to the extent necessary
to pay all Senior Indebtedness in full, after giving effect to any concurrent
payment or distribution to or for the holders of Senior Indebtedness.

                                      -60-
<PAGE>
         For purposes of this Article only, the words "any payment or
distribution of any kind or character, whether in cash, property or securities"
shall not be deemed to include a payment or distribution of stock or securities
of the Company provided for by a plan of reorganization or readjustment
authorized by an order or decree of a court of competent jurisdiction in a
reorganization proceeding under any applicable bankruptcy law or of any other
corporation provided for by such plan of reorganization or readjustment which
stock or securities are subordinated in right of payment to all then outstanding
Senior Indebtedness to substantially the same extent as the Securities are so
subordinated as provided in this Article. The consolidation of the Company with,
or the merger of the Company into, another person or the liquidation or
dissolution of the Company following the conveyance or transfer of all or
substantially all of its properties and assets as an entirety to another person
upon the terms and conditions set forth in Article 5 shall not be deemed a
Proceeding for the purposes of this Section if the person formed by such
consolidation or into which the Company is merged or the person which acquires
by conveyance or transfer such properties and assets as an entirety, as the case
may be, shall, as a part of such consolidation, merger, conveyance or transfer,
comply with the conditions set forth in Article 5.

SECTION 12.03 No Payment When Senior Indebtedness in Default.

         In the event that any Senior Payment Default (as defined below) shall
have occurred and be continuing, then no Securities Payment shall be made unless
and until such Senior Payment Default shall have been cured or waived or shall
have ceased to exist or all amounts then due and payable in respect of Senior
Indebtedness shall have been paid in full, or provision shall have been made for
such payment in cash or cash equivalents or otherwise in a manner satisfactory
to the holders of Senior Indebtedness. "Senior Payment Default" means any
default in the payment of principal of, premium, if any, or interest on any
Senior Indebtedness when due, whether at the maturity of any such payment or by
declaration of acceleration, call for redemption or otherwise and the default
continues beyond any grace period that the Company may have to make such
payments.

         In the event that any Senior Nonmonetary Default (as defined below)
shall have occurred and be continuing, then, upon the receipt by the Company and
the Trustee of written notice of such Senior Nonmonetary Default from an
Administrative Agent or, if there is no outstanding Designated Senior
Indebtedness, any representative of a holder of Senior Indebtedness, no
Securities Payment shall be made during the period (the "Payment Blockage
Period") commencing on the date of such receipt of such written notice and
ending on the earlier of (i) the date on which such Senior Nonmonetary Default
shall have been cured or waived or shall have ceased to exist and any
acceleration of Senior Indebtedness shall have been rescinded or annulled or the
Senior Indebtedness to which such Senior Nonmonetary Default relates shall have
been discharged or (ii) the 179th day after the date of such receipt of such
written notice. No more than one Payment Blockage Period may be commenced with
respect to the Securities during any 360-day period and there shall be a period
of at least 181 consecutive days in each 360-day period when no Payment Blockage
Period is in effect. No Payment Blockage Period shall be in effect if there is
no payment blockage period in effect with respect to any outstanding 10-1/2%
Senior Subordinated Notes due 2006 of the Company. For all purposes of this
paragraph, no Senior Nonmonetary Default that was known to the holders of Senior
Indebtedness to exist or be continuing on the date of commencement of any
Payment Blockage Period shall be, or be made, the basis for the commencement of
a subsequent Payment Blockage Period by an Administrative Agent for the
Designated Senior Indebtedness unless such Senior Nonmonetary Default shall have
been cured for a period of not less than 90 consecutive days. "Senior
Nonmonetary Default" means the occurrence or existence and continuance of any
event of default, or of any event which, after notice or lapse of time (or
both), would become an event of default, under the terms of any instrument
pursuant to which any Senior Indebtedness is outstanding, permitting (after
notice or lapse of time or both) one or more holders of such Senior Indebtedness
(or a trustee or

                                      -61-
<PAGE>
agent on behalf of the holders thereof) to declare such Senior Indebtedness due
and payable prior to the date on which it would otherwise become due and
payable, other than a Senior Payment Default.

SECTION 12.04 Payment Permitted If No Default.

         Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time except during
the pendency of any Proceeding referred to in Section 12.02 or under the
conditions described in Section 12.03, from making Securities Payments, or (b)
the application by the Trustee of any money deposited with it hereunder to
Securities Payments or the retention of such Securities Payment by the holders,
if, at the time of such application by the Trustee, it had not received any
notice set forth in Section 12.09.

SECTION 12.05 Subrogation to Rights of Holders of Senior Indebtedness.

         Subject to the payment in full of all amounts due or to become due on
or in respect of Senior Indebtedness, or the provision for such payment in cash
or cash equivalents or otherwise in a manner satisfactory to the holders of
Senior Indebtedness, the holders of the Securities shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness until the principal of, premium, if any, interest and Additional
Amounts, if any, on the Securities shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior
Indebtedness 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 payments over pursuant to the provisions of this Article to the
holders of Senior Indebtedness by holders of the Securities or the Trustee,
shall, as among the Company, its creditors other than holders of Senior
Indebtedness and the holders of the Securities, be deemed to be a payment or
distribution by the Company to or on account of the Senior Indebtedness.

SECTION 12.06 Provisions Solely to Define Relative Rights.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the holders on the one hand and the
holders of Senior Indebtedness on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the holders of the Securities, the obligation of the
Company, which is absolute and unconditional (and which, subject to the rights
under this Article of the holders of Senior Indebtedness, is intended to rank
equally with all other general obligations of the Company), to pay to the
holders of the Securities the principal of, premium, if any, interest and
Additional Amounts, if any, on the Securities as and when the same shall become
due and payable in accordance with their terms; or (b) affect the relative
rights against the Company of the holders of the Securities and creditors of the
Company other than the holders of Senior Indebtedness; or (c) prevent the
Trustee or the holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article of the holders of Senior Indebtedness to
receive cash, property and securities otherwise payable or deliverable to the
Trustee or such holder.

SECTION 12.07 Trustee to Effectuate Subordination.

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

                                      -62-
<PAGE>
SECTION 12.08 No Waiver of Subordination Provisions.

         No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance 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 Indebtedness 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 Indebtedness, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Indebtedness, or otherwise amend or supplement in any manner Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any person liable in any manner for the collection
of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights
against the Company and any other person.

SECTION 12.09 Notice to Trustee.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the 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 which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee or Administrative
Agent therefor; and, prior to the receipt of any such written notice, the
Trustee, subject to the provisions of Section 7.01, 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 at least
five business days prior to the date upon which by the terms hereof any money
may become payable for any purpose (including, without limitation, the payment
of the principal of, premium, if any, interest or Additional Amounts, if any, 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 which may be received by it within five
business days prior to such date.

         Subject to the provisions of Section 7.01, the Trustee shall be
entitled to conclusively rely on the delivery to it of a written notice by a
person representing himself to be a holder of Senior Indebtedness (or a trustee
or Administrative Agent therefor) to establish that such notice has been given
by a holder of Senior Indebtedness (or a trustee or Administrative Agent
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 Indebtedness to participate in any payment or distribution pursuant to
this Article, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such person, 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

                                      -63-
<PAGE>
this Article, 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 12.10 Reliance on Judicial Order or 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 7.01, and the
holders of the Securities shall be entitled to conclusively rely upon any order
or decree entered by any court of competent jurisdiction in which such
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
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

SECTION 12.11 Trustee Not Fiduciary for Holders of Senior Indebtedness.

         The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and it undertakes to perform and observe only
such of its covenants and obligations with respect to the Senior Indebtedness as
are specifically set forth in this Indenture, and no implied covenants or
obligations with respect to the Senior Indebtedness shall be read into this
Indenture against the Trustee and the Trustee 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 Indebtedness shall be entitled by
virtue of this Article or otherwise.

SECTION 12.12 Rights of Trustee as Holder of Senior Indebtedness; Preservation
              of Trustee's Rights.

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

         Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.07.

SECTION 12.13 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 in addition to or in place of the Trustee; provided,
however, that Section 12.12 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

                          WESTERN WIRELESS CORPORATION

                 4.625% CONVERTIBLE SUBORDINATED NOTES DUE 2023

1.       INTEREST. Western Wireless Corporation, a Washington corporation (the
         "Company"), promises to pay interest on the principal amount of this
         Security at the rate per annum shown above. The Company will pay
         interest semi-annually in arrears on June 15 and December 15 of each
         year, beginning December 15, 2003. Interest on the Securities will
         accrue from the most recent Interest Payment Date to which interest has
         been paid or duly provided for or, if no interest has been paid or duly
         provided for, from June 11, 2003. Each payment of interest on the
         Securities will include interest accrued through the day before the
         applicable Interest Payment Date (or Redemption Date, Repurchase Date
         or Fundamental Change Redemption Date). Any payment required to be made
         on any day that is not a business day will be made on the next
         succeeding business day. Interest and Additional Amounts, if any, will
         be computed on the basis of a 360-day year composed of twelve 30-day
         months.

2.       METHOD OF PAYMENT. The Company will pay interest and Additional
         Amounts, if any, on the Securities (except defaulted interest) to the
         person in whose name each Security is registered at the close of
         business on the June 1 or December 1 immediately preceding the relevant
         Interest Payment Date (other than with respect to a Security or portion
         thereof called for redemption on a Redemption Date, or repurchased at
         the option of any holder on a Repurchase Date or in connection with a
         Fundamental Change on a Fundamental Change Redemption Date, during the
         period from the close of business on a Regular Record Date to (but
         excluding) the next succeeding Interest Payment Date, in which case
         accrued interest and Additional Amounts, if any, shall be payable
         (unless such Security or portion thereof is converted) to the holder of
         the Security or portion thereof redeemed or repurchased in accordance
         with the applicable redemption or repurchase provisions of the
         Indenture). The holder must surrender Securities to the Paying Agent to
         collect principal payments. Each installment of semiannual interest and
         Additional Amounts, if any, on any Security shall be paid at the
         Corporate Trust Office or, at the Company's option, in same-day funds
         by wire transfer to an account maintained by the payee located inside
         the United States, if the Trustee shall have received proper wire
         transfer instructions from such payee not later than the relevant
         Interest Payment Date, Maturity Date, Redemption Date, Repurchase Date
         or Fundamental Change Redemption Date, as the case may be, or, if no
         such instructions have been received, by check drawn on a bank in New
         York City mailed to the payee at its address set forth in the Register.
         In the case of a Global Security, semiannual interest payable on any
         applicable payment date will be paid to the Depositary in same-days
         funds by wire transfer to an account designated by the Depositary, with
         respect to that portion of such Global Security held for its account by
         Cede & Co. for the purpose of permitting such party to credit the
         interest received by it in respect of such Global Security to the
         accounts of the beneficial owners thereof.

3.       REGISTRAR, PAYING AGENT AND CONVERSION AGENT. The Bank of New York, a
         New York banking corporation (together with any successor Trustee under
         the Indenture referred to below, the "Trustee"), will initially act as
         the Registrar, Paying Agent and Conversion Agent. The Company may
         change the Registrar, Paying Agent or Conversion Agent without prior
         notice to the holders of the Securities. Subject to certain limitations
         in the Indenture, the Company or any of its subsidiaries may act in any
         such capacity.

                                      A-4
<PAGE>
4.       INDENTURE. The Company issued the Securities under an Indenture dated
         as of June 11, 2003 (the "Indenture") between the Company and the
         Trustee. The terms of the Securities include those stated in the
         Indenture (and any supplemental indenture entered into pursuant to
         Section 9.03) and those made part of the Indenture by reference to the
         Trust Indenture Act of 1939 (15 U.S. Code Section 77aaa-77bbbb) (the
         "TIA") as in effect on the date of the Indenture (and the date of any
         applicable supplemental indenture entered into pursuant to Section
         9.03). The Securities are subject to, and qualified by, all such terms,
         certain of which are summarized herein, and holders are referred to the
         Indenture and the TIA for a statement of such terms. In the event of
         any conflict or inconsistency between the terms of the Indenture and
         the Securities, the terms of the Indenture shall control. The
         Securities are subordinated unsecured obligations of the Company
         limited to (except as otherwise provided in the Indenture) up to
         $115,000,000 in aggregate principal amount. Capitalized terms not
         defined herein have the same meaning given to them in the Indenture.

5.       REDEMPTION AT THE OPTION OF THE COMPANY. No sinking fund is provided
         for the Securities. The Securities are redeemable as a whole, or from
         time to time in part, at any time at the option of the Company in
         accordance with the Indenture and this Security at the Redemption
         Prices set forth below, provided that the Securities are not redeemable
         prior to June 18, 2006.

         If redeemed at the option of the Company, the Securities will be
         redeemed on the conditions and at the Redemption Prices set forth
         below.

         If the Closing Sale Price of the Common Stock has exceeded 150% of the
         then applicable Conversion Price for at least 20 trading days in any
         consecutive 30-day trading period ending on the trading day prior to
         the date of mailing of the notice of redemption, the Company may redeem
         for cash all or a portion of the Securities at any time after June 18,
         2006 but prior to June 18, 2010 at a price equal to 100% of the
         principal amount of the Securities to be redeemed plus accrued and
         unpaid interest and any Additional Amounts to, but excluding, the
         Redemption Date, plus the Make Whole Payment (as defined below). The
         Company must pay the Make Whole Payment on all Securities called for
         redemption prior to June 18, 2010, including on any Securities
         converted after the date the notice of redemption is mailed.

         "Make Whole Payment" means an amount equal to the present value of all
         remaining scheduled payments of interest on the Securities to be
         redeemed through and including June 15, 2010. The present value of the
         remaining interest payments will be computed using a discount rate
         equal to the Treasury Yield plus 25 basis points. "Treasury Yield"
         means the yield to maturity at the time of computation of United States
         Treasury securities with a constant maturity (as compiled and published
         in the most recent Federal Reserve Statistical Release H.15 (519) that
         has become publicly available at least two business days prior to the
         date fixed for conversion (or, if such Statistical Release is no longer
         published, any publicly available source for similar market data)) most
         nearly equal to the then remaining term to June 15, 2010; provided,
         however, that if the then remaining term to June 15, 2010 is not equal
         to the constant maturity of a United States Treasury security for which
         a weekly average yield is given, the Treasury Rate shall be obtained by
         linear interpolation (calculated to the nearest one-twelfth of a year)
         from the weekly average yields of United States Treasury securities for
         which such yields are given, except that if the then remaining term to
         June 15, 2010 is less than one year, the weekly average yield on
         actually traded United States Treasury securities adjusted to a
         constant maturity of one year shall be used.

                                      A-5
<PAGE>
         If the Closing Sale Price of the Common Stock has exceeded 125% of the
         then applicable Conversion Price for at least 20 trading days in any
         consecutive 30-day trading period ending on the trading day prior to
         the date of mailing of the notice of redemption, the Company may redeem
         for cash all or a portion of the Securities at any time on or after
         June 18, 2010 but prior to June 18, 2013 at a price equal to 100% of
         the principal amount of the Securities to be redeemed plus accrued and
         unpaid interest and any Additional Amounts to, but excluding, the
         Redemption Date.

         On or after June 18, 2013, the Company may redeem for cash all or a
         portion of the Securities at any time at a price equal to 100% of the
         principal amount of the Securities to be redeemed plus accrued and
         unpaid interest and any Additional Amounts to, but excluding, the
         Redemption Date.

         The notice of redemption shall be mailed by first-class mail, postage
         prepaid 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, and any accrued and unpaid interest, Additional Amounts and
         Make Whole Payment on, 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, on such Redemption Date, interest
         and any Additional Amounts shall cease to accrue on such Securities or
         portions thereof. Securities in denominations larger than $1,000 in
         principal amount may be redeemed in part, but only in integral
         multiples of $1,000 in principal amount.

6.       PURCHASE BY THE COMPANY AT THE OPTION OF THE HOLDER. Subject to the
         terms and conditions of the Indenture, the Company shall become
         obligated to purchase, at the option of the holder, the Securities held
         by such holder on June 15, 2013 and June 15, 2018 at a Repurchase Price
         equal to 100% of the principal amount of such Securities on the
         applicable Repurchase Date plus accrued and unpaid interest and
         Additional Amounts, if any, to, but not including, the Repurchase Date,
         upon delivery of a Repurchase Notice by the holder to the Paying Agent
         containing the information set forth in the Indenture, at any time from
         the opening of business on the date that is twenty business days prior
         to such Repurchase Date until the close of business on the third
         business day prior to such Repurchase Date and upon delivery or
         book-entry transfer of the Securities to the Paying Agent by the holder
         as set forth in the Indenture.

         The Repurchase Price may be paid, at the option of the Company, in cash
         or by the issuance and delivery of shares of Common Stock of the
         Company in accordance with the Indenture.

         At the option of the holder and subject to the terms and conditions of
         the Indenture, upon the occurrence of a Fundamental Change prior to the
         Maturity Date, the Company shall become obligated to purchase all or a
         portion of the Securities in integral multiples of $1,000 principal
         amount held by such holder on the date that is thirty days after the
         date of the Fundamental Change Notice at a Fundamental Change
         Redemption Price, to be paid in cash, equal to 100% of the principal
         amount of such Securities plus accrued and unpaid cash interest and
         Additional Amounts, if any, to, but not including, the Fundamental
         Change Redemption Date.

         Holders have the right to withdraw any Repurchase Notice or Fundamental
         Change 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 or Securities sufficient to pay the Repurchase Price or cash
         sufficient to pay the Fundamental Change Redemption Price, as the case
         may be, of all Securities or portions thereof

                                      A-6
<PAGE>
         to be purchased as of the Repurchase Date or the Fundamental Change
         Redemption Date, as the case may be, is deposited with the Paying
         Agent, on the business day following the Repurchase Date or the
         Fundamental Change Redemption Date, as the case may be, cash interest
         and Additional Amounts, if any, shall cease to accrue on such
         Securities (or portions thereof) on such Repurchase Date or Fundamental
         Change Redemption Date, as the case may be, and the holder thereof
         shall have no other rights as such (other than the right to receive the
         Repurchase Price or Fundamental Change Redemption Price, as the case
         may be, if any, upon surrender of such Security).

7.       DENOMINATIONS, TRANSFER, EXCHANGE. The Securities are in registered
         form without coupons in denominations of $1,000 and integral multiples
         of $1,000. The transfer of Securities may be registered and Securities
         may be exchanged as provided in the Indenture.

8.       PERSONS DEEMED OWNERS. The registered holder of a Security will be
         treated as its owner for all purposes.

9.       AMENDMENTS AND WAIVERS. Subject to certain exceptions, the Indenture or
         the Securities may be amended or supplemented with the consent of the
         holders of at least a majority in aggregate principal amount of the
         then outstanding Securities (including consents obtained in connection
         with a tender offer or exchange offer for the Securities), and any
         existing default (except a default in the payout of principal of,
         premium, if any, interest and Additional Amounts, if any, (other than a
         default in the payout of principal of, premium, if any, interest and
         Additional Amounts, if any, that has become due solely by virtue of an
         acceleration that has not been duly rescinded)) may be waived with the
         consent of the holders of a majority in aggregate principal amount of
         the then outstanding Securities (including consents obtained in
         connection with a tender offer or exchange offer for the Securities).

         Without the consent of any holder, the Indenture or the Securities may
         be amended by the Company and the Trustee to: (i) cure any ambiguity,
         defect or inconsistency or make any other changes in the provisions of
         the Indenture which the Company and the Trustee may deem necessary or
         desirable, provided such amendment does not materially and adversely
         affect the rights of the holders of Securities under the Indenture or
         the Securities; (ii) provide for uncertificated Securities in addition
         to or in place of certificated Securities; (iii) evidence the
         succession of another person to the Company and providing for the
         assumption by such successor of the covenants and obligations of the
         Company under the Indenture and in the Securities as permitted by
         Section 5.01 of the Indenture; (iv) provide for conversion rights of
         holders of Securities in the event of consolidation, merger, share
         exchange or sale, assignment, transfer, lease, conveyance or other
         disposition of all or substantially all of the properties or assets of
         the Company as an entirety or substantially as an entirety as required
         to comply with Sections 5.01 and/or 11.14 of the Indenture; (v) reduce
         the Conversion Price; (vi) evidence and provide for the acceptance of
         the appointment under the Indenture of a successor Trustee; (vii) in
         exchange for holders of Securities agreeing to waive their right to
         require the Company to purchase all or a portion of their Securities on
         a specified Repurchase Date, adding additional Repurchase Dates on
         which holders of Securities may require the Company to purchase all or
         a portion of their Securities at the applicable Repurchase Price and
         paying such holders of Securities additional cash payments in
         connection therewith; (viii) make any change that would provide any
         additional rights or benefits to the holders of Securities or that does
         not adversely affect the legal rights under the Indenture of any such
         holder; or (ix) comply with the requirements of the Commission in order
         to effect or maintain the qualification of the Indenture under the TIA.

         consent to an amendment, supplement or waiver; (ii) reduce the
         principal of, or premium on, or change the fixed maturity of any
         Security or, except as permitted pursuant to clauses (i), (vii), (viii)

         interest or Additional Amounts, if any, on the Securities (except a
         rescission of acceleration of the Securities by the holders of at least
         a majority in aggregate principal amount of the Securities then
         outstanding and a waiver of the payment default that resulted from such
         acceleration); (vi) make the principal of, or premium, if any, or
         interest or Additional Amounts, if any, on any Security payable in
         money or securities other than as provided for in the Indenture and in
         the Securities; (vii) make any change in the provisions of the

         of the Securities in a manner adverse to the holders thereof; or (x)
         make any change to the abilities of holders of Securities to enforce
         their rights under the Indenture or the provisions of clauses (i)
         through (ix) above.

10.      DEFAULTS AND REMEDIES. An Event of Default means any one of the
         following events: (a) default in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity Date; or (b) default
         in the payment of any interest and any Additional Amount on any
         Security when it becomes due and payable, and continuance of such
         default for a period of 30 days; or (c) failure to comply with or
         observe in any material respect any covenant or warranty of the Company
         in the Indenture (other than a covenant or warranty a Default in whose
         performance or whose breach is elsewhere in this paragraph specifically
         dealt with), and continuance of such failure to comply with or observe
         for a period of 60 days after there has been given, by registered or
         certified mail, to the Company by the Trustee or to the Company and the
         Trustee by the holders of at least 25% in aggregate principal amount of
         the outstanding Securities a written notice specifying such failure to
         observe or comply with and requiring it to be remedied; or (d) default
         in the payment of the Redemption Price, Repurchase Price or Fundamental
         Change Redemption Price (including any accrued and unpaid interest or
         Additional Amount or Make Whole Payment) when the it becomes due and
         payable; or (e) failure to provide timely notice of any Fundamental
         Change in accordance with Section 3.14(b) of the Indenture; or (f) a
         default or defaults under any bond(s), debenture(s), note(s) or other
         evidence(s) of Indebtedness by the Company or any Restricted Subsidiary
         of the Company or under any mortgage(s), indenture(s) or instrument(s)
         under which there may be issued or by which there may be secured or
         evidenced any Indebtedness of such type by the Company or any such
         Restricted Subsidiary with a principal amount then outstanding,
         individually or in the aggregate, in excess of $5 million, whether such
         Indebtedness now exists or shall hereafter be created, which default or
         defaults shall constitute a failure to pay any portion of the principal
         of such Indebtedness at final maturity after the expiration of any
         applicable grace period with respect thereto or shall have resulted in
         such Indebtedness becoming or being declared due and payable prior to
         the date on which it would otherwise have become due and payable; or
         (g) certain events involving bankruptcy, insolvency

                                      A-8
<PAGE>
         or reorganization occurs with respect to the Company or a Restricted
         Subsidiary as set forth in the Indenture.

         If an Event of Default (other than an Event of Default with respect to
         the Company specified in Paragraph 10(g)) occurs and is continuing,
         then and in every such case the Trustee, by written notice to the
         Company, or the holders of at least 25% in aggregate principal amount
         of the then outstanding Securities, by written notice to the Company
         and the Trustee, may declare the unpaid principal of, premium, if any,
         and accrued and unpaid interest and Additional Amounts, if any, on all
         Securities then outstanding to be due and payable. Upon such
         declaration such principal amount, premium, if any, and accrued and
         unpaid interest and Additional Amounts, if any, shall become
         immediately due and payable, notwithstanding anything contained in the
         Indenture or the Securities to the contrary. If any Event of Default
         with respect to the Company specified in Paragraph 10(g) occurs, all
         unpaid principal of and premium, if any, and accrued and unpaid
         interest and Additional Amounts, if any, on the Securities then
         outstanding shall become automatically due and payable, without any
         declaration or other act on the part of the Trustee or any holder of
         Securities.

         Holders of Securities may not enforce the Indenture or the Securities
         except as provided in the Indenture. The Trustee shall be under no
         obligation to exercise any of the rights or powers vested in it by the
         Indenture at the request, order or direction of any of the holders of
         Securities pursuant to the provisions of the Indenture, unless such
         holders have offered to the Trustee security or indemnity satisfactory
         to it against the costs, expenses and liabilities which might be
         incurred thereby. Subject to certain limitations, holders of a majority
         in aggregate principal amount of the then outstanding Securities may
         direct the Trustee in its exercise of any trust or power. If a Default
         or Event of Default occurs and is continuing and is known to a Trust
         Officer of the Trustee, the Indenture requires the Trustee to mail a
         notice of such Default or Event of Default to each holder within 90
         days of the occurrence of such Default or Event of Default. The Trustee
         may withhold from holders notice of any continuing Default or Event of
         Default (except a Default or Event of Default in the payment of
         principal of, premium, if any, or interest or Additional Amounts, if
         any, on the Securities) if it determines in good faith that withholding
         notice is in their interest. The Company must furnish annual compliance
         certificates to the Trustee.

11.      TRUSTEE DEALINGS WITH THE COMPANY. Subject to Sections 7.10 and 7.11 of
         the Indenture, the Trustee in its individual or any other capacity may
         become the owner or pledgee of Securities with the same rights it would
         have if it were not the Trustee and may otherwise deal with the Company
         or an Affiliate of the Company and receive, collect, hold and retain
         collections from the Company with the same rights it would have if it
         were not Trustee. Any Agent may do the same with like rights.

12.      NO RECOURSE AGAINST OTHERS. No director, officer, employee, stockholder
         or Affiliate, as such, of the Company from time to time shall 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. Each holder by accepting a Security
         waives and releases all such liability. The waiver and release are part
         of the consideration for the Securities. Each of such directors,
         officers, employees, stockholders and Affiliates is a third party
         beneficiary of this paragraph 12.

                                      A-9

13.      AUTHENTICATION. This Security shall not be valid until authenticated by
         the manual signature of the Trustee or an authenticating agent.

14.      ABBREVIATIONS. Customary abbreviations may be used in the name of a
         holder or an assignee, such as: TEN CO = tenants in common, TEN ENT =
         tenants by the entireties, JT TEN = joint tenants with right of
         survivorship and not as tenants in common, CUST = Custodian and U/G/M/A
         = Uniform Gifts to Minors Act.

15.      CONVERSION. Subject to and upon compliance with the provisions of the
         Indenture, each holder of Securities shall have the right, at his or
         her option, at any time on or before the close of business on the last
         trading day prior to the Maturity Date (subject to the next paragraph),
         to convert the principal amount of any Security held by such holder, or
         any portion of such principal amount which is $1,000 or an integral
         multiple thereof, into that number of fully paid and non-assessable
         shares of Common Stock (as such shares shall then be constituted)
         obtained by multiplying (i) the principal amount of the Securities or
         portion thereof to be converted by (ii) a conversion rate of 64.6998
         shares per $1,000 principal amount of Securities (as adjusted from time
         to time as provided in the Indenture, the "Conversion Rate"). The
         initial Conversion Rate is equivalent to a conversion price of $15.456
         per share (the "Conversion Price").

         Notwithstanding the foregoing paragraph, the holders' right to
         conversion will terminate: (a) with respect to any Security or portion
         thereof which is called for redemption prior to the last trading day
         prior to the Maturity Date, on the close of business on the last
         trading day preceding the Redemption Date (unless the Company defaults
         in payment of the redemption price in which case the conversion right
         will terminate at the close of business on the date such default is
         cured) and (b) with respect to any Security or portion thereof subject
         to a duly completed election for repurchase, on the close of business
         on the 30th day after the date of the Fundamental Change Notice (unless
         the Company defaults in the payment due upon repurchase or such holder
         elects to withdraw the submission of such election to repurchase in
         accordance with Section 3.14 of the Indenture).

         To convert a Security, a holder must surrender this Security to the
         Conversion Agent, accompanied by a completed and manually signed
         conversion notice a form of which is on the back of this Security (and
         if the shares of Common Stock to be issued on conversion are to be
         issued in any name other than that of the registered holder of this
         Security, furnish appropriate endorsements and transfer documents, in
         form satisfactory to the Company, duly executed by the registered
         holder or its duly authorized attorney and pay all transfer and similar
         taxes) and, in case such surrender shall be made during the period from
         the close of business on the Regular Record Date immediately preceding
         any Interest Payment Date through the close of business on the last
         trading day immediately preceding such Interest Payment Date (unless
         this Security or the portion thereof being converted has been called
         for redemption on a date in such period), also accompanied by payment,
         in funds acceptable to the Company, of an amount equal to the interest
         and Additional Amounts, if any, otherwise payable on such Interest
         Payment Date on the principal amount of the Security then being
         converted. Subject to the aforesaid requirement for a payment in the
         event of conversion after the close of business on a Regular Record
         Date immediately preceding an Interest Payment Date, no adjustment
         shall be made on conversion for any interest or Additional Amounts
         accrued hereon or for any dividends on Common Stock delivered on
         conversion.

                                      A-10

         In lieu of delivery of Common Stock otherwise deliverable upon notice
         of conversion of any Securities, the Company may elect to pay holders
         surrendering Securities an amount in cash (for each share of Common
         Stock otherwise so deliverable) equal to the average of the Closing
         Sale Prices of Common Stock for the five consecutive trading days
         immediately following either (a) the date of notice of election to
         deliver cash as described below if the Company has not given notice of
         redemption, or (b) the Conversion Date, in the case of conversion
         following the notice of redemption specifying that the Company intends
         to deliver cash upon conversion. The Company will inform the holders
         through the Trustee no later than two business days following the
         conversion date of its election to deliver shares of Common Stock or to
         pay cash in lieu of delivery of Common Stock, unless the Company has
         already informed holders of its election in connection with its
         optional redemption of the Securities pursuant to Section 3.01 of the
         Indenture. If the Company elects to deliver such payment in Common
         Stock, the Common Stock will be delivered through the Conversion Agent
         no later than the fifth business day following the Conversion Date. If
         the Company elects to pay such payment in cash, the payment will be
         made to holders surrendering Securities no later than the tenth
         business day following the Conversion Date. If an Event of Default
         (other than a default in a cash payment upon conversion of the
         Securities) has occurred and is continuing, the Company may not pay
         cash upon conversion of any Security or portion of a Security (other
         than cash for fractional shares).

         The Conversion Rate (and, simultaneously, the Conversion Price) will be
         adjusted for dividends or distributions on Common Stock payable in
         Common Stock or other Capital Stock of the Company; subdivisions,
         combinations or certain reclassifications of Common Stock;
         distributions to all holders of Common Stock of certain rights to
         purchase Common Stock for a period expiring within 60 days of the
         record date for such distribution at less than the Closing Sale Price
         of the Common Stock at the Time of Determination; and distributions to
         such holders of Common Stock of assets or debt securities of the
         Company or certain rights to purchase securities of the Company
         (excluding certain cash dividends or distributions). However, no
         adjustment need be made if holders of Securities may participate in the
         transaction or in certain other cases. The Company from time to time
         may (to the extent permitted by applicable law) voluntarily increase
         the Conversion Rate (and, simultaneously, reduce the Conversion Price
         by any amount for any period of at least 20 days, in which case the
         Company shall give at least 15 days' notice of such decrease, if the
         Board of Directors has made a determination that such decrease would be
         in the Company's best interests, which determination shall be
         conclusive.

         The Company will not issue a fractional share of Common Stock upon
         conversion of a Security. A holder of a Security otherwise entitled to
         a fractional share will receive cash equal to the applicable portion of
         the Closing Sale Price of Common Stock on the trading day immediately
         preceding the Conversion Date.

         No adjustment in the Conversion Rate (or Conversion Price) need be made
         unless the adjustment would require an increase or decrease of at least
         1% in the Conversion Rate (or Conversion Price). Any adjustments that
         are not made shall be carried forward and taken into account in any
         subsequent adjustment and all adjustments that are made and carried
         forward shall be taken in the aggregate in order to determine if the 1%
         threshold is met.

16.      SUBORDINATION. The indebtedness evidenced by this Security is, to the
         extent provided in the Indenture, subordinate and subject in right of
         payment to the prior payment in full of all Senior Indebtedness, and
         this Security is issued subject to the provisions of the Indenture with
         respect thereto. Each holder of this Security, by accepting the same,
         (a) agrees to and shall be

                                      A-11
<PAGE>
         bound by such provisions, (b) authorizes and directs the Trustee on his
         behalf to take such action as may be necessary or appropriate to
         effectuate the subordination so provided and (c) appoints the Trustee
         his attorney-in-fact for any and all such purposes.

17.      REGISTRATION RIGHTS AGREEMENT. The holder of this Security is entitled
         to the benefits of the Registration Rights Agreement. All capitalized
         terms used in this paragraph 17 not herein defined have the meanings
         ascribed to them in the Registration Rights Agreement. Pursuant to the
         Registration Rights Agreement, the Company has agreed for the benefit
         of the holders of the Securities and the Common Stock issuable upon
         conversion of the Securities, that (i) it will, at its cost, within 90
         days after the Issue Date, file a Shelf Registration Statement with the
         Commission with respect to resales of the Securities and the Common
         Stock issuable upon conversion thereof, (ii) the Company will use
         commercially reasonable efforts to cause the Initial Shelf Registration
         Statement to be declared effective by the Commission under the
         Securities Act within 180 days after the Issue Date and (iii) the
         Company will use commercially reasonable efforts to keep the Initial
         Shelf Registration Statement (or any Subsequent Shelf Registration
         Statement) continuously effective under the Securities Act until the
         earliest of (a) the period of two years from the Issue Date or, if
         later, two years from the last date on which any Additional Notes are
         issued upon the exercise of the Initial Purchasers' option to purchase
         Additional Notes pursuant to the Purchase Agreement and (b) the period
         ending on the date that all Registrable Securities have ceased to be
         Registrable Securities. Each Holder of Registrable Securities wishing
         to sell Registrable Securities pursuant to a Shelf Registration
         Statement and related Prospectus agrees to deliver a Notice and
         Questionnaire to the Company at any time before or after the Initial
         Shelf Registration Statement is declared effective that is at least
         five (5) Business Days prior to any intended distribution of
         Registrable Securities under the Shelf Registration Statement.

         If (i) the Initial Shelf Registration Statement has not been filed on
         or prior to the Filing Deadline Date, (ii) the Initial Shelf
         Registration Statement has not been declared effective under the
         Securities Act on or prior to the Effectiveness Deadline Date, or (iii)
         the aggregate duration of Deferral Periods in any period exceeds the
         number of days permitted in respect of such period pursuant to Section
         3(i) of the Registration Rights Agreement (each of the events of a type
         described in any of the foregoing clauses (i) through (iii) is
         individually referred to herein as an "Event," and the Filing Deadline
         Date in the case of clause (i), the Effectiveness Deadline Date in the
         case of clause (ii), and the date on which the aggregate duration of
         Deferral Periods in any period exceeds the number of days permitted by
         Section 3(i) of the Registration Rights Agreement in the case of clause
         (iii), being referred to herein as an "Event Date"), then, commencing
         on (and including) any Event Date and ending on (but excluding) the
         next date after an Event Termination Date (an "Additional Amount
         Accrual Period"), the Company agrees to pay an Additional Amount,
         payable on the Additional Amount Payment Dates to Record Holders of
         then outstanding Notes that are Registrable Securities or of then
         outstanding shares of Underlying Common Stock issued upon conversion of
         Notes that are Registrable Securities, as the case may be, accruing,
         for each portion of such Additional Amount Accrual Period beginning on
         and including an Additional Amount Payment Date (or, in respect of the
         first time that the Additional Amount is to be paid to Holders on a

to be made on a delayed or continuous basis pursuant to Rule 415 of the

Registration Statement"). The Initial Shelf Registration Statement shall be on

held by it covered by such Shelf Registration Statement unless such Holder has
provided a Notice and Questionnaire in accordance with Section 2(d) and is in
compliance with Section 4. The Company shall not permit any of its security
holders (other than the Holders of Registrable Securities) to include any of the

Shelf Registration Statement).

            (b) If the Initial Shelf Registration Statement or any Subsequent
Shelf Registration Statement ceases to be effective for any reason at any time
during the Effectiveness Period, the Company shall use commercially reasonable
efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event shall within thirty (30) days of such
cessation of effectiveness amend the Shelf Registration Statement in a manner
reasonably expected by the Company to obtain the withdrawal of the order
suspending the effectiveness thereof, or file an additional Shelf Registration
Statement covering all of the securities that as of the date of such filing are
Registrable Securities (a "Subsequent Shelf Registration Statement"). If a
Subsequent Shelf Registration Statement is filed, the Company shall use
commercially reasonable efforts to cause the Subsequent Shelf Registration
Statement to become effective as promptly as is reasonably practicable after
such filing or, if filed during a Deferral Period, after the expiration of such
Deferral Period, and to keep such Registration Statement (or Subsequent Shelf
Registration Statement), subject to Section 3(i)(A), continuously effective
until the end of the Effectiveness Period.

            (c) The Company shall supplement and amend the Shelf Registration
Statement if required by the rules, regulations or instructions applicable to
the registration form used by the Company for such Shelf Registration Statement,
if required by the Securities Act or, to the extent to which the Company does
not reasonably object, as

                                       5
<PAGE>
reasonably requested by the Initial Purchasers or by the Trustee on behalf of
the registered Holders.

            (d) Each Holder of Registrable Securities agrees that if such Holder
wishes to sell Registrable Securities pursuant to a Shelf Registration Statement
and related Prospectus, it will do so only in accordance with this Section 2(d)
and Section 3(i) and Section 4. Each Holder of Registrable Securities wishing to
sell Registrable Securities pursuant to a Shelf Registration Statement and
related Prospectus agrees to deliver a Notice and Questionnaire to the Company
at any time before or after the Initial Shelf Registration Statement is declared
effective that is at least five (5) Business Days prior to any intended
distribution of Registrable Securities under the Shelf Registration Statement.
From and after the date the Initial Shelf Registration Statement is declared
effective, the Company shall, as promptly as is reasonably practicable after the
date a fully completed and legible Notice and Questionnaire is received by the
Company, but in any event within ten (10) Business Days of such receipt, (i) if
required by applicable law, file with the SEC a post-effective amendment to the
Shelf Registration Statement or prepare and, if required by applicable law, file
a supplement to the related Prospectus or a supplement or amendment to any
document incorporated therein by reference or file any other document required
by the SEC so that the Holder delivering such Notice and Questionnaire is named
as a selling security holder in the Shelf Registration Statement and the related
Prospectus in such a manner as to permit such Holder to deliver such Prospectus
to purchasers of the Registrable Securities in accordance with applicable
federal securities law (other than laws not generally applicable to all Holders
of Registrable Securities wishing to sell Registrable Securities pursuant to the
Shelf Registration Statement and related Prospectus) and, if the Company shall
file a post-effective amendment to the Shelf Registration Statement, use
reasonable efforts to cause such post-effective amendment to be declared
effective under the Securities Act as promptly as is reasonably practicable;
(ii) provide such Holder copies of any documents filed pursuant to Section
2(d)(i); and (iii) notify such Holder as promptly as is reasonably practicable
after the effectiveness under the Securities Act of any post-effective amendment
filed pursuant to Section 2(d)(i); provided that if such Notice and
Questionnaire is delivered during a Deferral Period, the Company shall so inform
the Holder delivering such Notice and Questionnaire and shall take the actions
set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral
Period in accordance with Section 3(i), provided further that if under
applicable law the Company has more than one option as to the type or manner of
making any such filing, it will make the required filing or filings in the
manner or of a type that is reasonably expected to result in the earliest
availability of the Prospectus for effecting resales of Registrable Securities.
Notwithstanding anything contained herein to the contrary, the Company shall be
under no obligation to name any Holder that is not a Notice Holder as a selling
security holder in any Registration Statement or related Prospectus; provided,
however, that any Holder that becomes a Notice Holder pursuant to the provisions
of Section 2(d) of this Agreement (whether or not such Holder was a Notice
Holder at the time the Registration Statement was initially declared effective)
shall be named as a selling security holder in

                                       6
<PAGE>
the Registration Statement or related Prospectus subject to and in accordance
with the requirements of this Section 2(d).

            (e) The parties agree that the Holders of Registrable Securities
will suffer damages, and that it would not be feasible to ascertain the extent
of such damages with precision, if (i) the Initial Shelf Registration Statement
has not been filed on or prior to the Filing Deadline Date, (ii) the Initial
Shelf Registration Statement has not been declared effective under the
Securities Act on or prior to the Effectiveness Deadline Date, or (iii) the
aggregate duration of Deferral Periods in any period exceeds the number of days
permitted in respect of such period pursuant to Section 3(i) (each of the events
of a type described in any of the foregoing clauses (i) through (iii) is
individually referred to herein as an "Event," and the Filing Deadline Date in
the case of clause (i), the Effectiveness Deadline Date in the case of clause
(ii), and the date on which the aggregate duration of Deferral Periods in any
period exceeds the number of days permitted by Section 3(i) in the case of
clause (iii), being referred to herein as an "Event Date"). Events shall be
deemed to continue until the "Event Termination Date," which shall be the
following dates with respect to the respective types of Events: the date the
Initial Shelf Registration Statement is filed in the case of an Event of the
type described in clause (i), the date the Initial Shelf Registration Statement
is declared effective under the Securities Act in the case of an Event of the
type described in clause (ii), and termination of the Deferral Period that
caused the limit on the aggregate duration of Deferral Periods in a period set
forth in Section 3(i) to be exceeded in the case of the commencement of an Event
of the type described in clause (iii).

            Accordingly, commencing on (and including) any Event Date and ending
on (but excluding) the next date after an Event Termination Date (an "Additional
Amount Accrual Period"), the Company agrees to pay an additional amount (the
"Additional Amount"), payable on the Additional Amount Payment Dates to Record
Holders of then outstanding Notes that are Registrable Securities or of then
outstanding shares of Underlying Common Stock issued upon conversion of Notes
that are Registrable Securities, as the case may be, accruing, for each portion
of such Additional Amount Accrual Period beginning on and including an
Additional Amount Payment Date (or, in respect of the first time that the
Additional Amount is to be paid to Holders on a Additional Amount Payment Date
as a result of the occurrence of any particular Event, from the Event Date) and
ending on but excluding the first to occur of (A) the date of the end of the
Additional Amount Accrual Period or (B) the next Additional Amount Payment Date,
at a rate per annum equal to one-quarter of one percent (0.25%), for the first
ninety (90)-day period from the Event Date, and at a rate per annum equal to
one-half of one percent (0.50%), thereafter, of each $1,000 principal amount of
Notes or the Conversion Price of each share of Underlying Common Stock, as the
case may be, in each case determined as of the Business Day immediately
preceding the next Additional Amount Payment Date; provided that any Additional
Amount accrued with respect to any Note or portion thereof called for redemption
on a redemption date or converted into Underlying Common Stock on a conversion
date shall, in any such event, be paid instead to the Holder who submitted such
Note or portion thereof for redemption or conversion

                                       7
<PAGE>
on the applicable redemption date or conversion date, as the case may be, on
such date (or promptly following the conversion date, in the case of
conversion). Notwithstanding the foregoing, no Additional Amounts shall accrue
as to any Registrable Security from and after the earlier of (x) the date such
security is no longer a Registrable Security and (y) expiration of the
Effectiveness Period. The rate of accrual of the Additional Amount with respect
to any period shall not exceed the rate provided for in this paragraph
notwithstanding the occurrence of multiple concurrent Events. Following the cure
of all Events requiring the payment by the Company of Additional Amounts to the
Holders of Registrable Securities pursuant to this Section, the accrual of
Additional Amounts will cease (without in any way limiting the effect of any
subsequent Event requiring the payment of the Additional Amount by the Company).

            The Trustee, subject to the applicable provisions of the Indenture,
shall be entitled on behalf of Holders of Notes to seek any available remedy for
the enforcement of this Agreement, including for the payment of any Additional
Amount. Notwithstanding the foregoing, the parties agree that the sole monetary
damages payable for a violation of the terms of this Agreement with respect to
which additional amounts are expressly provided shall be such Additional Amount.
Nothing shall preclude a Notice Holder or Holder of Registrable Securities from
pursuing or obtaining specific performance or other equitable relief with
respect to this Agreement.

            All of the Company's obligations set forth in this Section 2(e) that
are outstanding with respect to any Registrable Security at the time such
security ceases to be a Registrable Security shall survive until such time as
all such obligations with respect to such security have been satisfied in full
(notwithstanding termination of this Agreement pursuant to Section 8(k)).

            The parties agree that the Additional Amounts provided for in this
Section 2(e) constitute a reasonable estimate of the damages that may be
incurred by Holders of Registrable Securities by reason of the failure of the
Shelf Registration Statement to be filed or declared effective or available for
effecting resales of Registrable Securities in accordance with the provisions
hereof.

            SECTION 3. Registration Procedures. In connection with the
registration obligations of the Company under Section 2 hereof, the Company
shall:

            (a) Before filing any Registration Statement or Prospectus or any
amendments or supplements (other than amendments or supplements that do nothing
more substantive than name one or more Notice Holders as selling security
holders) thereto with the SEC, furnish to the Initial Purchasers copies of all
such documents proposed to be filed and use reasonable efforts to reflect in
each such document when so filed with the SEC such comments as the Initial
Purchasers reasonably shall propose within three (3) Business Days of the
delivery of such copies to the Initial Purchasers.

            (b) Prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such

                                       8
<PAGE>
Registration Statement continuously effective for the applicable period
specified in Section 2(a); cause the related Prospectus to be supplemented by
any required Prospectus supplement, and as so supplemented to be filed pursuant
to Rule 424 (or any similar provisions then in force) under the Securities Act;
and use reasonable efforts to comply with the provisions of the Securities Act
applicable to it with respect to the disposition of all securities covered by
such Registration Statement during the Effectiveness Period in accordance with
the intended methods of disposition by the sellers thereof set forth in such
Registration Statement as so amended or such Prospectus as so supplemented.

            (c) As promptly as reasonably practicable give notice to the Notice
Holders and the Initial Purchasers (i) when any Prospectus, Prospectus
supplement, Registration Statement or post-effective amendment to a Registration
Statement has been filed with the SEC and, with respect to a Registration
Statement or any post-effective amendment, when the same has been declared
effective, (ii) of any request, following the effectiveness of the Initial Shelf
Registration Statement under the Securities Act, by the SEC or any other federal
or state governmental authority for amendments or supplements to any
Registration Statement or related Prospectus or for additional information
related thereto, (iii) of the issuance by the SEC or any other federal or state
governmental authority of any stop order or injunction suspending or enjoining
the use of any Prospectus or the effectiveness of any Registration Statement or
the initiation of any proceedings for that purpose, (iv) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction or the initiation of any proceeding for such purpose, (v) of
the occurrence of (but not the nature of or details concerning) a Material Event
(provided, however, that no notice by the Company shall be required pursuant to
this clause (v) in the event that the Company promptly files a Prospectus
supplement to update the Prospectus or the Company files a Current Report on
Form 8-K or other appropriate Exchange Act report that is incorporated by
reference into the Registration Statement, which, in either case, contains the
requisite information with respect to such Material Event that results in such
Registration Statement no longer containing any untrue statement of material
fact or omitting to state a material fact necessary to make the statements
contained therein not misleading) and (vi) of the determination by the Company
that a post-effective amendment to a Registration Statement will be filed with
the SEC, which notice may, at the discretion of the Company (or as required
pursuant to Section 3(i)), state that it constitutes a Deferral Notice, in which
event the provisions of Section 3(i) shall apply.

            (d) Use reasonable efforts to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement or the lifting of any
suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction in which they have been
qualified for sale, in either case at the earliest possible moment or, if any
such order or suspension is made effective during any Deferral Period, at the
earliest possible moment after the expiration of such Deferral Period.

                                       9
<PAGE>
            (e) If reasonably requested by the Initial Purchasers or any Notice
Holder, as promptly as reasonably practicable incorporate in a Prospectus
supplement or post-effective amendment to a Registration Statement such
information as the Initial Purchasers or such Notice Holder shall, on the basis
of an opinion of nationally recognized counsel experienced in such matters,
determine to be required to be included therein by applicable law and make any
required filings of such Prospectus supplement or such post-effective amendment
as required by applicable law; provided that the Company shall not be required
to take any actions under this Section 3(e) that are not, in the reasonable
opinion of counsel for the Company, in compliance with applicable law.

            (f) As promptly as reasonably practicable after the filing of such
documents with the SEC, furnish to each Notice Holder and the Initial
Purchasers, upon their request and without charge, at least one (1) conformed
copy of the Registration Statement and any amendment thereto, including
financial statements, but excluding schedules, all documents incorporated or
deemed to be incorporated therein by reference and all exhibits (unless
requested in writing to the Company by such Notice Holder or the Initial
Purchasers, as the case may be).

            (g) During the Effectiveness Period (except during such periods that
a Deferral Notice is outstanding and has not been revoked), deliver to each
Notice Holder in connection with any sale of Registrable Securities pursuant to
a Registration Statement, without charge, as many copies of the Prospectus or
Prospectuses relating to such Registrable Securities and any amendment or
supplement thereto as such Notice Holder may reasonably request; and the Company
hereby consents (except during such periods that a Deferral Notice is
outstanding and has not been revoked) to the use of such Prospectus or each
amendment or supplement thereto by each Notice Holder in connection with any
offering and sale of the Registrable Securities covered by such Prospectus or
any amendment or supplement thereto in the manner set forth therein.

            (h) Subject to Section 3(i), prior to any public offering of the
Registrable Securities pursuant to the Shelf Registration Statement, use
reasonable efforts to register or qualify or cooperate with the Notice Holders
in connection with the registration or qualification (or exemption from such
registration or qualification) of such Registrable Securities for offer and sale
under the securities or Blue Sky laws of such jurisdictions within the United
States as any Notice Holder reasonably requests in writing (which request may be
included in the Notice and Questionnaire), it being agreed that no such
registration or qualification will be made unless so requested; prior to any
public offering of the Registrable Securities pursuant to the Shelf Registration
Statement, use reasonable efforts to keep each such registration or
qualification (or exemption therefrom) effective during the Effectiveness Period
in connection with such Notice Holder's offer and sale of Registrable Securities
pursuant to such registration or qualification (or exemption therefrom) and do
any and all other acts or things necessary to enable the disposition in such
jurisdictions of such Registrable Securities in the manner set forth in the
relevant Registration Statement and the related Prospectus; provided that the
Company will not be required to (i) qualify as a foreign corporation or as a
dealer in

                                       10
<PAGE>
securities in any jurisdiction where it is not otherwise qualified or (ii) take
any action that would subject it to general service of process in suits or to
taxation in any such jurisdiction where it is not then so subject.

            (i) Upon (A) the issuance by the SEC of a stop order suspending the
effectiveness of the Shelf Registration Statement or the initiation of
proceedings with respect to the Shelf Registration Statement under Section 8(d)
or 8(e) of the Securities Act, (B) the occurrence of any event or the existence
of any fact (a "Material Event") as a result of which any Registration Statement
shall contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, or any Prospectus shall contain any untrue statement of
a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading (including, in any such case, as a result of the
non-availability of financial statements), or (C) the occurrence or existence of
any development, event, fact, situation or circumstance relating to the Company
that, in the sole discretion of the Company, makes it appropriate to suspend the
availability of the Shelf Registration Statement and the related Prospectus, (i)
in the case of clause (B) above, subject to the next sentence, as promptly as
practicable prepare and file a post-effective amendment to such Registration
Statement or a supplement to the related Prospectus or any document incorporated
therein by reference or file any other required document that would be
incorporated by reference into such Registration Statement and Prospectus so
that such Registration Statement does not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading, and such Prospectus
does not contain any untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, as thereafter
delivered to the purchasers of the Registrable Securities being sold thereunder,
and, in the case of a post-effective amendment to a Registration Statement,
subject to the next sentence, use reasonable efforts to cause it to be declared
effective as promptly as is reasonably practicable, and (ii) in the case of
clauses (A), (B) and (C) above, give notice to the Notice Holders that the
availability of the Shelf Registration Statement is suspended (a "Deferral
Notice") and, upon receipt of any Deferral Notice, each Notice Holder agrees not
to sell any Registrable Securities pursuant to the Registration Statement until
such Notice Holder's receipt of copies of the supplemented or amended Prospectus
provided for in clause (i) above, or until it is advised in writing by the
Company that the Prospectus may be used, and has received copies of any
additional or supplemental filings that are incorporated or deemed incorporated
by reference in such Prospectus. The Company will use reasonable efforts to
ensure that the use of the Prospectus may be resumed (x) in the case of clause
(A) above, as promptly as is practicable, (y) in the case of clause (B) above,
as soon as, in the sole judgment of the Company, public disclosure of such
Material Event would not be prejudicial to or contrary to the interests of the
Company or, if necessary to avoid unreasonable burden or expense, as soon as
reasonably practicable thereafter and (z) in the case of clause (C) above, as
soon as, in the sole discretion of the Company, such suspension is no longer
appropriate. So long as the

                                       11
<PAGE>
period during which the availability of the Registration Statement and any
Prospectus is suspended (the "Deferral Period") does not exceed thirty (30) days
during any three (3) month period or ninety (90) days during any twelve (12)
month period, the Company shall not incur any obligation to pay Additional
Amounts pursuant to Section 2(e).

            (j) If reasonably requested in writing in connection with a
disposition of Registrable Securities pursuant to a Registration Statement, make
reasonably available for inspection during reasonable business hours by a
representative for the Notice Holders of such Registrable Securities and any
broker-dealers, attorneys and accountants retained by such Notice Holders, all
relevant financial and other records, pertinent corporate documents and
properties of the Company and its subsidiaries, and cause the appropriate
executive officers, directors and designated employees of the Company and its
subsidiaries to make reasonably available for inspection during normal business
hours all relevant information reasonably requested by such representative for
the Notice Holders or any such broker-dealers, attorneys or accountants in
connection with such disposition, in each case as is customary for similar "due
diligence" examinations; provided, however, that such persons shall first agree
in writing with the Company that any information that is reasonably designated
by the Company in writing as confidential at the time of delivery of such
information shall be kept confidential by such persons and shall be used solely
for the purposes of exercising rights under this Agreement, unless (i)
disclosure of such information is required by court or administrative order or
is necessary to respond to inquiries of regulatory authorities; (ii) disclosure
of such information is required by law (including any disclosure requirements
pursuant to federal securities laws in connection with the filing of any
Registration Statement or the use of any Prospectus referred to in this
Agreement), (iii) such information becomes generally available to the public
other than as a result of a disclosure or failure to safeguard by any such
person or (iv) such information becomes available to any such person from a
source other than the Company and such source is not bound by a confidentiality
agreement or otherwise obligated to keep such information confidential; and
provided further that the foregoing inspection and information gathering shall,
to the greatest extent possible, be coordinated on behalf of all the Notice
Holders and the other parties entitled thereto by the counsel referred to in
Section 5.

            (k) Comply with all applicable rules and regulations of the SEC and
make generally available to its security holders earning statements (which need
not be audited) satisfying the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder (or any similar Rule promulgated under the Securities
Act) no later than forty-five (45) days after the end of any twelve (12)-month
period (or ninety (90) days after the end of any twelve (12)-month period if
such period is a fiscal year) commencing on the first day of the first fiscal
quarter of the Company commencing after the effective date of a Registration
Statement, which statements shall cover said twelve (12)-month periods.

            (l) Cooperate with each Notice Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities
sold pursuant to a Registration Statement, and cause such Registrable Securities
to be in such

                                       12
<PAGE>
denominations as are permitted by the Indenture and registered in such names as
such Notice Holder may request in writing at least two (2) Business Days prior
to any sale of such Registrable Securities.

            (m) Provide a CUSIP number for all Registrable Securities covered by
each Registration Statement not later than the effective date of such
Registration Statement and provide the Trustee for the Notes and the transfer
agent for the Common Stock with certificates for the Registrable Securities that
are in a form eligible for deposit with The Depository Trust Company.

            (n) Make a reasonable effort to provide such information as is
required for any filings required to be made with the National Association of
Securities Dealers, Inc.

            (o) Upon the effectiveness of the Initial Shelf Registration
Statement, announce the same, in each case by release to Businesswire, Reuters
Economic Services, Bloomberg Business News or any other means of dissemination
reasonably expected to make such information known publicly.

            (p) Take all actions reasonably necessary, or reasonably requested
by the holders of a majority of the Registrable Securities being sold, in order
to expedite or facilitate disposition of such Registrable Securities; provided
that the Company shall not be required to take any action in connection with an
underwritten offering without its consent.

            (q) Cause the Indenture to be qualified under the TIA not later than
the effective date of any Registration Statement; and in connection therewith,
cooperate with the Trustee to effect such changes to the Indenture as may be
required for the Indenture to be so qualified in accordance with the terms of
the TIA and execute, and use reasonable efforts to cause the Trustee to execute,
all documents as may be required to effect such changes, and all other forms and
documents required to be filed with the SEC to enable the Indenture to be so
qualified in a timely manner.

            (r) Cause all Underlying Common Stock to be listed on each
securities exchange or quotation system on which the Common Stock is then listed
no later than the date the Initial Shelf Registration Statement is declared
effective and, in connection therewith, to make such filings as may be required
under the Exchange Act and to have such filings declared effective as and when
required thereunder.

            SECTION 4. Holder's Obligations. Each Holder agrees, by acquisition
of the Registrable Securities, that no Holder of Registrable Securities shall be
entitled to sell any of such Registrable Securities pursuant to a Registration
Statement or to receive a Prospectus relating thereto, unless such Holder has
furnished the Company with a Notice and Questionnaire as required pursuant to
Section 2(d) hereof (including the information required to be included in such
Notice and Questionnaire) and the information set forth in the next sentence.
Each Notice Holder agrees to furnish promptly to the Company in

                                       13
<PAGE>
writing all information required to be disclosed in order to make the
information previously furnished to the Company by such Notice Holder not
misleading, any other information regarding such Notice Holder and the
distribution of such Registrable Securities as may be required to be disclosed
in the Registration Statement under applicable law or pursuant to SEC comments
and any information otherwise required by the Company to comply with applicable
law or regulations. Each Holder further agrees, following termination of the
Effectiveness Period, to notify the Company, within ten (10) Business Days of a
request, of the amount of Registrable Securities sold pursuant to the
Registration Statement and, in the absence of a response, the Company may assume
that all of the Holder's Registrable Securities were so sold.

            SECTION 5. Registration Expenses. The Company shall bear all fees
and expenses incurred in connection with the performance by the Company of its
obligations under Sections 2 and 3 of this Agreement whether or not any of the
Registration Statements are declared effective. Such fees and expenses shall
include, without limitation, (i) all registration and filing fees (including,
without limitation, fees and expenses (x) with respect to filings required to be
made with the National Association of Securities Dealers, Inc. and (y) of
compliance with federal and state securities or Blue Sky laws to the extent such
filings or compliance are required pursuant to this Agreement (including,
without limitation, reasonable fees and disbursements of the counsel specified
in the next sentence in connection with Blue Sky qualifications of the
Registrable Securities)), (ii) printing expenses (including, without limitation,
expenses of printing certificates for Registrable Securities in a form eligible
for deposit with The Depository Trust Company), (iii) duplication expenses
relating to copies of any Registration Statement or Prospectus delivered to any
Holders hereunder, (iv) fees and disbursements of counsel for the Company in
connection with the Shelf Registration Statement, and (v) reasonable fees and
disbursements of the Trustee and its counsel and of the registrar and transfer
agent for the Common Stock. In addition, the Company shall bear or reimburse the
Notice Holders for the reasonable fees and disbursements of one firm of legal
counsel for the Holders, which shall, upon the written consent of the Initial
Purchasers (which shall not be unreasonably withheld), be a nationally
recognized law firm experienced in securities law matters designated by the
Company. In addition, the Company shall pay its internal expenses (including,
without limitation, all salaries and expenses of officers and employees
performing legal or accounting duties), and its expenses for any annual audit,
the fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange on which the same securities of the
Company are then listed and the fees and expenses of any person, including
special experts, retained by the Company.

            SECTION 6. Indemnification; Contribution.

            (a) The Company agrees to indemnify and hold harmless each Initial
Purchaser and each Holder of Registrable Securities and each person, if any, who
controls any Initial Purchaser or any holder of Registrable Securities within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act, as follows:

                                       14
<PAGE>
                  (i) against any and all loss, liability, claim, damage and
            expense whatsoever, as incurred, arising out of any untrue statement
            or alleged untrue statement of a material fact contained in the
            Registration Statement (or any amendment thereto), or the omission
            or alleged omission therefrom of a material fact required to be
            stated therein or necessary in order to make the statements therein,
            in light of the circumstances under which they were made, not
            misleading or arising out of any untrue statement or alleged untrue
            statement of a material fact included in any preliminary prospectus
            or the Prospectus (or any amendment or supplement thereto), or the
            omission or alleged omission therefrom of a material fact necessary
            in order to make the statements therein, in the light of the
            circumstances under which they were made, not misleading;

                  (ii) against any and all loss, liability, claim, damage and
            expense whatsoever, as incurred, to the extent of the aggregate
            amount paid in settlement of any litigation, or any investigation or
            proceeding by any governmental agency or body, commenced or
            threatened, or of any claim whatsoever based upon any such untrue
            statement or omission, or any such alleged untrue statement or
            omission, provided that (subject to Section 6(d) below) any such
            settlement is effected with the prior written consent of the
            Company; and

                  (iii) subject to Section 6(c) below, against any and all
            expense whatsoever, as incurred (including the reasonable fees and
            disbursements of counsel), reasonably incurred in investigating,
            preparing or defending against any litigation, or any investigation
            or proceeding by any governmental agency or body, commenced or
            threatened, or any claim whatsoever based upon any such untrue
            statement or omission, or any such alleged untrue statement or
            omission, to the extent that any such expense is not paid under (i)
            or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by or
on behalf of the Initial Purchasers, such Holder of Registrable Securities
(which also acknowledges the indemnity provisions herein) or any person, if any,
who controls any Initial Purchaser or any such Holder of Registrable Securities
expressly for use in the Registration Statement (or any amendment thereto), or
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto); provided further that this indemnity agreement shall not apply to any
loss, liability, claim, damage or expense (1) arising from an offer or sale of
Registrable Securities occurring during a Deferral Period, if a Deferral Notice
was given to such Notice Holder or (2) if the Holder fails to deliver at or
prior to the written confirmation of sale, the most recent Prospectus, as
amended or supplemented, and such Prospectus, as amended or supplemented, would
have corrected such untrue statement or omission or alleged untrue statement or
omission of a material fact and the delivery thereof was required by law.

                                       15
<PAGE>
            (b) In connection with any Shelf Registration Statement in which a
Holder, including, without limitation, the Initial Purchasers of Registrable
Securities is participating, in furnishing information relating to such Holder
of Registrable Securities to the Company in writing expressly for use in such
Registration Statement, any preliminary prospectus, the Prospectus or any
amendments or supplements thereto, the Holders of such Registrable Securities
agree, severally and not jointly, to indemnify and hold harmless the Initial
Purchasers and each person, if any, who controls any Initial Purchaser within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act and the Company and each person, if any, who controls the Company
within the meaning of either such Section, against any and all loss, liability,
claim, damage and expense described in the indemnity contained in subsection (a)
of this Section, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto) or any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto) in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
such Holder of Registrable Securities (which also acknowledges the indemnity
provisions herein) or any person, if any, who controls any such Holder of
Registrable Securities expressly for use in the Registration Statement (or any
amendment thereto) or such preliminary prospectus or the Prospectus (or any
amendment or supplement thereto).

            The Initial Purchasers agree severally to indemnify and hold
harmless the Company, the Holders of Registrable Securities, and each person, if
any, who controls the Company or any Holder of Registrable Securities within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act against any and all loss, liability, claim, damage and expense described in
the indemnity contained in subsection (a) of this Section 6, as incurred, but
only with respect to untrue statements or omissions, or alleged untrue
statements or omissions, made in the Registration Statement (or any amendment
thereto) or any preliminary prospectus or the Prospectus (or any amendment or
supplement thereto) in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Initial Purchasers expressly for
use in the Registration Statement (or any amendment thereto) or such preliminary
prospectus or the Prospectus (or any amendment or supplement thereto).

            (c) Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action or proceeding
commenced against it in respect of which indemnity may be sought hereunder, but
failure to so notify an indemnifying party shall not relieve such indemnifying
party from any liability hereunder to the extent it is not materially prejudiced
as a result thereof and in any event shall not relieve it from any liability
which it may have otherwise than on account of these indemnity provisions. The
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the reasonable fees and disbursements of such counsel related to such
proceeding. In any such proceeding, any indemnified party shall have the right
to

                                       16
<PAGE>
retain a separate firm as its own counsel, but the fees and expenses of such
counsel shall be at the expense of such indemnified party unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is understood that the indemnifying party shall not, in respect of the legal
expenses of any indemnified party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for (A) the reasonable fees and
expenses of more than one firm (in addition to any local counsel) for the
Initial Purchasers, Holders of Registrable Securities, and all persons, if any,
who control any Initial Purchaser or Holder of Registrable Securities within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act or (B) the reasonable fees and expenses of more than one firm (in addition
to any local counsel) for the Company, its directors, and each person, if any,
who controls the Company within the meaning of either such Section, and that all
such reasonable fees and expenses shall be reimbursed as they are incurred. In
the event a separate firm is retained for the Initial Purchasers, Holders of
Registrable Securities, and control persons of the Initial Purchasers and
Holders of Registrable Securities, such firm shall be designated in writing by
the Initial Purchasers. In the event a separate firm is retained for the Company
and its directors, officers and control persons, such firm shall be designated
in writing by the Company. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 6 (whether or not the indemnified parties are
actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

            (d) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 6(a)(ii) effected without its
written consent if (i) such settlement is entered into more than sixty (60) days
after receipt by such indemnifying party of aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least forty-five (45) days prior to such settlement being entered into and (iii)
such indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement; provided that
an indemnifying party shall not be liable for any such settlement effected
without its consent if such indemnifying party (1) reimburses such indemnified
party in accordance with such request to the extent it considers such request to
be reasonable and (2) provides written notice to the indemnified party
describing any unpaid balance it believes is unreasonable and the reasons
therefor, in each case prior to the date of such settlement.

                                       17
<PAGE>
            (e) If the indemnification to which an indemnified party is entitled
under this Section 6 is for any reason unavailable to or insufficient although
applicable in accordance with its terms to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
therein, then each indemnifying party shall contribute to the aggregate amount
of such losses, liabilities, claims, damages and expenses incurred by such
indemnified party, as incurred, in such proportion as is appropriate to reflect
the relative fault of the indemnifying party or parties on the one hand and of
the indemnified party on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

            The relative fault of the Company on the one hand and the holders of
the Registrable Securities or the Initial Purchasers on the other hand shall be
determined by reference to, among other things, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company or by the
holder of the Registrable Securities or the Initial Purchasers and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(e) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section 6(e). The
aggregate amount of losses, liabilities, claims, damages, and expenses incurred
by an indemnified party and referred to above in this Section 6(e) shall be
deemed to include any out-of-pocket legal or other expenses reasonably incurred
by such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

            Notwithstanding the provisions of this Section 6, neither the Holder
of any Registrable Securities nor any Initial Purchaser shall be required to
indemnify or contribute any amount in excess of the amount by which the total
price at which the Registrable Securities sold by such Holder of Registrable
Securities or by such Initial Purchaser, as the case may be, and distributed to
the public exceeds the amount of any damages that such Holder of Registrable
Securities or such Initial Purchaser has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission.

            No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

            For purposes of this Section 6(e), each person, if any, who controls
any Initial Purchaser or any holder of Registrable Securities within the meaning
of Section 15

                                       18
<PAGE>
of the Securities Act or Section 20 of the Exchange Act shall have the same
rights to contribution as such Initial Purchaser or such holder, and each
person, if any, who controls the Company within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act shall have the same rights to
contribution as the Company.

            SECTION 7. Information Requirements. The Company covenants that, if
at any time before the end of the Effectiveness Period the Company is not
subject to the reporting requirements of the Exchange Act, it will cooperate
with any Holder of Registrable Securities and take such further reasonable
action as any Holder of Registrable Securities may reasonably request in writing
(including, without limitation, making such reasonable representations as any
such Holder may reasonably request), all to the extent required from time to
time to enable such Holder to sell Registrable Securities without registration
under the Securities Act within the limitations of Rule 144 and Rule 144A under
the Securities Act and customarily taken in connection with sales pursuant to
such exemptions. Upon the written request of any Holder of Registrable
Securities, the Company shall deliver to such Holder a written statement as to
whether it has complied with such filing requirements, unless such a statement
has been included in the Company's most recent annual or quarterly report
required to be filed and filed pursuant to Section 13 or Section 15(d) of the
Exchange Act. Notwithstanding the foregoing, nothing in this Section 7 shall be
deemed to require the Company to register any of its securities under any
section of the Exchange Act.

            SECTION 8. Miscellaneous.

            (a) No Conflicting Agreements. The Company is not, as of the date
hereof, a party to, nor shall it, on or after the date of this Agreement, enter
into, any agreement with respect to the Company's securities that conflicts with
the rights granted to the Holders of Registrable Securities in this Agreement.
The Company represents and warrants that the rights granted to the Holders of
Registrable Securities hereunder do not in any way conflict with the rights
granted to the holders of the Company's securities under any other agreements.

            (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the Company has obtained the written consent of Holders
of a majority of the then outstanding Underlying Common Stock constituting
Registrable Securities (with Holders of Notes deemed to be the Holders, for
purposes of this Section, of the number of outstanding shares of Underlying
Common Stock into which such Notes are or would be convertible or exchangeable
as of the date on which such consent is requested). Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates exclusively to the rights of Holders of Registrable
Securities whose securities are being sold pursuant to a Registration Statement
and that does not directly or indirectly affect the rights of other Holders of
Registrable Securities

                                       19
<PAGE>
may be given by Holders of at least a majority of the Registrable Securities
being sold by such Holders pursuant to such Registration Statement; provided
that the provisions of this sentence may not be amended, modified, or
supplemented except in accordance with the provisions of the immediately
preceding sentence. Each Holder of Registrable Securities outstanding at the
time of any such amendment, modification, supplement, waiver or consent or
thereafter shall be bound by any such amendment, modification, supplement,
waiver or consent effected pursuant to this Section 8(b), whether or not any
notice, writing or marking indicating such amendment, modification, supplement,
waiver or consent appears on the Registrable Securities or is delivered to such
Holder.

            (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, by telecopier, by
courier guaranteeing overnight delivery or by first-class mail, return receipt
requested, and shall be deemed given (i) when made, if made by hand delivery,
(ii) upon confirmation, if made by telecopier, (iii) one (1) Business Day after
being deposited with such courier, if made by overnight courier, or (iv) on the
date indicated on the notice of receipt, if made by first-class mail, to the

such Holder to the Company in a Notice and Questionnaire or any amendment
thereto;

            (d) Approval of Holders. Whenever the consent or approval of Holders
of a specified percentage of Registrable Securities is required hereunder,
Registrable Securities held by the Company or its Affiliates (other than the
Initial Purchasers or subsequent Holders of Registrable Securities if such
subsequent Holders are deemed to be such affiliates solely by reason of their
holdings of such Registrable Securities) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage.

            (e) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the parties
hereto and, without requiring any express assignment, shall inure to the benefit
of and be binding upon each Holder of any Registrable Securities; provided that
nothing herein shall be deemed to permit any assignment, transfer of other
disposition of Registrable Securities in violation of the terms of the Purchase
Agreement. If any transferee of any Holder shall acquire Registrable Securities
in any manner, whether by operation of law or otherwise, such Registrable
Securities shall be subject to all of the terms of this Agreement and by taking
and holding such Registrable Securities, such person shall be conclusively
deemed to have agreed to be bound by and to perform all of the terms and
provisions of this Agreement.

            (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be original and all of which taken together
shall constitute one and the same agreement.

            (g) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

            (h) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

            (i) Severability. If any term, provision, covenant or restriction of
this Agreement is held to be invalid, illegal, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions set forth herein
shall remain in full force and

                                       21
<PAGE>
effect and shall in no way be affected, impaired or invalidated thereby, and the
parties hereto shall use their best efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction, it being intended that all of
the rights and privileges of the parties hereto shall be enforceable to the
fullest extent permitted by law.

            (j) Entire Agreement. This Agreement is intended by the parties
hereto as a final expression of their agreement and is intended to be a complete
and exclusive statement of the agreement and understanding of the parties hereto
in respect of the subject matter contained herein and the registration rights
granted by the Company with respect to the Registrable Securities. Except as
provided in the Purchase Agreement, there are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein,
with respect to the registration rights granted by the Company with respect to
the Registrable Securities. This Agreement supersedes all prior agreements and
undertakings among the parties hereto with respect to such registration rights.

            (k) Termination. This Agreement and the obligations of the parties
hereunder shall terminate upon the expiration of the Effectiveness Period,
except for (i) any liabilities or obligations under Section 4, 5 or 6 hereof and
the obligations to make payments of and provide for Additional Amounts under
Section 2(e) hereof to the extent such liabilities or obligations accrue prior
to the end of the Effectiveness Period, each of which shall remain in effect in
accordance with its terms.
