in respect of Notes and this Indenture may be served by the holders of the
Notes. The Registrar shall keep a Register ("Register") of the Notes 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 "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, Conversion Agent or co-registrar 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, Conversion Agent or
co-registrar 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 Paying Agent, Registrar, Conversion Agent or
co-registrar, except that for purposes of Articles III and VIII and Section
4.06, 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, or
Paying Agent or Conversion Agent, the Trustee shall act as such, and 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 Notes or the Trustee all money held by the Paying Agent for the
payment of principal or interest on the Notes, 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 Notes 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 Notes 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 (15) 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 Notes.

     SECTION 2.06. Transfer and Exchange. (a) When Notes are presented to the
Registrar or a co-registrar with a request to register a transfer or to exchange
them for an equal principal amount of

                                       11

<PAGE>

Notes 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 Notes 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 may require payment of a
sum sufficient to cover any transfer tax or other governmental charge payable
upon exchanges pursuant to Sections 2.10, 3.07, 9.05 or 12.02.

          The Company or the Registrar shall not be required to register the
transfer of any Notes surrendered for repurchase pursuant to Section 4.06.

          All Notes issued upon any transfer or exchange of Notes in accordance
with this Indenture shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture as the
Notes 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 Section 2.10
and this Section 2.06(a).

          Except for transfers or exchanges made in accordance with paragraphs
(i) through (iv) of this Section 2.06(b) and Section 2.10, transfers of a Global
Security shall be limited to transfers of such Global Security in whole, but not
in part, to nominees of the Depositary or to a successor of the Depositary or
such successor's nominee.

               (i) Global Security To Definitive Security. If an owner of a
     beneficial interest in a Global Security deposited with the Depositary or
     with the Trustee as custodian for the Depositary wishes at any time to
     transfer its interest in such Global Security to a Person who is required
     to take delivery thereof in the form of a Definitive Security, such owner
     may, subject to the rules and procedures of the Depositary, cause the
     exchange of such interest for one or more Definitive Securities of any
     authorized denomination or denominations and of the same aggregate
     principal amount. Upon receipt by the Registrar of instructions from the
     Depositary directing the Trustee to authenticate and deliver one or more
     Definitive Securities of the same aggregate principal amount as the
     beneficial interest in the Global Security to be exchanged, such
     instructions to contain the name or names of the designated transferee or
     transferees, the authorized denomination or denominations of the Definitive
     Securities to be so issued and appropriate delivery instructions, then the
     Registrar will instruct the Depositary to reduce or cause to be reduced
     such Global Security by the aggregate principal amount of the beneficial
     interest therein to be exchanged and to debit or cause to be debited from
     the account of the Person making such transfer the beneficial interest in
     the Global Security that is being transferred, and concurrently with such
     reduction and debit the Company shall execute, and the Trustee shall
     authenticate and deliver, one or more Definitive Securities of the same
     aggregate principal amount in accordance with the instructions referred to
     above.

               (ii) Definitive Security to Definitive Security. If a holder of a
     Definitive Security wishes at any time to transfer such Definitive Security
     (or portion thereof) to a Person who is required to take delivery thereof
     in the form of a Definitive Security, such holder may, subject to the
     restrictions on transfer set forth herein and in such Definitive Security,
     cause the transfer of such Definitive Security (or any portion thereof in a
     principal amount equal to an authorized denomination) to such transferee.
     Upon receipt by the Registrar of (1) such Definitive

                                       12

<PAGE>

     Security, duly endorsed as provided herein, and (2) instructions from such
     holder directing the Trustee to authenticate and deliver one or more
     Definitive Securities of the same aggregate principal amount as the
     Definitive Security (or portion thereof) to be transferred, such
     instructions to contain the name or names of the designated transferee or
     transferees, the authorized denomination or denominations of the Definitive
     Securities to be so issued and appropriate delivery instructions, then the
     Registrar, shall cancel or cause to be canceled such Definitive Security
     and concurrently therewith, the Company shall execute, and the Trustee
     shall authenticate and deliver, one or more Definitive Securities in the
     appropriate aggregate principal amount, in accordance with the instructions
     referred to above and, if only a portion of a Definitive Security is
     transferred as aforesaid, concurrently therewith Company shall execute and
     the Trustee shall authenticate and deliver to the transferor a Definitive
     Security in a principal amount equal to the principal amount which has not
     been transferred. A holder of a Definitive Security may at any time
     exchange such Definitive Security for one or more Definitive Securities of
     other authorized denominations and in the same aggregate principal amount
     and registered in the same name by delivering such Definitive Security,
     duly endorsed as provided herein, to the Trustee together with instructions
     directing the Trustee to authenticate and deliver one or more Definitive
     Securities in the same aggregate principal amount and registered in the
     same name as the Definitive Security to be exchanged, and the Registrar
     thereupon shall cancel or caused to be canceled such Definitive Security
     and concurrently therewith the Company shall execute and Trustee shall
     authenticate and deliver, one or more Definitive Securities in the same
     aggregate principal amount and registered in the same name as the
     Definitive Security being exchanged.

               (iii) Definitive Security to Global Security. If a holder of a
     Definitive Security wishes at any time to transfer such Definitive Security
     (or portion thereof) to a Person who is not required to take delivery
     thereof in the form of a Definitive Security, such holder shall, subject to
     the restrictions on transfer set forth herein and in such Definitive
     Security and the rules of the Depositary cause the exchange of such
     Definitive Security for a beneficial interest in the Global Security. Upon
     receipt by the Registrar of (1) such Definitive Security, duly endorsed as
     provided herein, (2) instructions from such holder directing the Trustee to
     increase the aggregate principal amount of the Global Security deposited
     with the Depositary or with the Trustee as custodian for the Depositary by
     the same aggregate principal amount as the Definitive Security to be
     exchanged, such instructions to contain the name or names of a member of,
     or participant in, the Depositary that is designated as the transferee, the
     account of such member or participant and other appropriate delivery
     instructions, and (3) the assignment form on the back of the Definitive
     Security completed in full, then the Trustee shall cancel or cause to be
     canceled such Definitive Security and concurrently therewith shall increase
     the aggregate principal amount of the Global Security by the same aggregate
     principal amount as the Definitive Security canceled.

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

          (b) 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 Notes (including any transfers between or among 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.

     SECTION 2.07. Replacement Notes. If the holder of a Note claims that the
Note has been lost, destroyed or wrongfully taken, the Company shall issue and
the Trustee shall authenticate a

                                       13

<PAGE>

replacement Note if the Trustee's requirements are met. If required by the
Trustee or the Company as a condition of receiving a replacement Note, the
holder of a Note 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 Note is replaced. The Company and the Trustee may charge the
relevant holder for their expenses in replacing any Note.

          The Trustee or any authenticating agent may authenticate any such
substituted Note, and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating
agent may require. Upon the issuance of any substituted Note, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses connected
therewith. In case any Note which has matured or is about to mature, or has been
submitted for repurchase pursuant to Section 4.06 or is about to be converted
into Common Stock pursuant to Article XII, shall become mutilated or be
destroyed, lost or stolen, the Company may, instead of issuing a substitute
Note, 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 Note), 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 authenticating agent
such security or indemnity as may be required by them 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, any paying agent or
conversion agent of the destruction, loss or theft of such Note and of the
ownership thereof.

          Every replacement Note 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 Notes duly issued, authenticated and delivered
hereunder.

     SECTION 2.08. Outstanding Notes. The Notes outstanding at any time are all
the Notes properly authenticated by the Trustee except for those canceled by the
Trustee, those delivered to it for cancellation, and those described in this
Section as not outstanding.

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

          If Notes are considered paid under Section 4.01 or converted under
Article XII, they cease to be outstanding and interest on them ceases to accrue.

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

     SECTION 2.09. When Treasury Notes Disregarded. In determining whether the
holders of the required principal amount of Notes have concurred in any
direction, waiver or consent, Notes 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 Notes which the Trustee knows are so
owned shall be so disregarded.

     SECTION 2.10. Temporary Notes.

          (a) Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Notes. Temporary Notes
shall be substantially in the form of definitive Notes but may have variations
that the Company considers appropriate for temporary Notes and

                                       14

<PAGE>

shall be reasonably acceptable to the Trustee. Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate definitive Notes in
exchange for temporary Notes.

          (b) Except for transfers made in accordance with Section 2.06(a), 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 Notes 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 (ii) an Event of
Default has occurred and is continuing.

          (c) Any Global Security or interest thereon that is transferable to
the beneficial owners thereof in the form of certificated Notes 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 Notes of authorized denominations in the form of
certificated Notes 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.

          (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 Notes.

          (e) The Company will make available to the Trustee a reasonable supply
of certificated Notes in definitive form without interest coupons.

     SECTION 2.11. Cancellation. The Company at any time may deliver Notes to
the Trustee for cancellation. The Registrar and Paying Agent shall forward to
the Trustee any Notes surrendered to them for registration of transfer, exchange
or payment. The Trustee and no one else may cancel Notes surrendered for
registration of transfer, exchange, payment, replacement, conversion, repurchase
or cancellation. Upon written instructions of the Company, the Trustee shall
destroy and dispose of canceled Notes as the Company directs and, after such
destruction, shall deliver a certificate of destruction to the Company. The
Company may not issue new Notes to replace Notes that it has paid or repurchased
or that have been delivered to the Trustee for cancellation or that any holder
has (i) converted pursuant to Article XII hereof, or (ii) submitted for
repurchase pursuant to Section 4.06 hereof (unless revoked).

     SECTION 2.12. Defaulted Interest. If the Company fails to make a payment of
interest on the Notes, 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 Notes on a subsequent special record date. The Company shall fix any
such special record date and payment date. At least 15 days before any such
special record date, the Company shall mail to holders of the Notes a notice
that states the special record date, payment date and amount of such interest to
be paid.

     SECTION 2.13. CUSIP Number. The Company in issuing the Notes may use a
"CUSIP" number, and if so, such CUSIP number shall be included in notices of
repurchase or exchange as a convenience to holders of Notes; 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
Notes and

                                       15

<PAGE>

that reliance may be placed only on the other identification numbers printed on
the Notes. The Company will promptly notify the Trustee of any change in the
CUSIP number.

                             [INTENTIONALLY OMITTED]

                                   ARTICLE IV
                                    COVENANTS

     SECTION 4.01. Payment of Notes. The Company shall pay the principal of and
interest on the Notes on the dates and in the manner provided in the Notes.
Principal, interest or the Designated Event Payment shall be considered paid on
the date due if the Trustee or Paying Agent (other than the Company or a
Subsidiary of the Company) holds as of 10:00 a.m. New York City time on that
date immediately available funds designated for and sufficient to pay all
principal, interest and the Designated Event Payment then due; provided,
however, that money held by the Agent for the benefit of holders of Senior Debt
pursuant to the provisions of Article XI hereof or the payment of which to the
holders of the Notes is prohibited by Article XI shall not be considered to be
designated for the payment of any principal of or interest on the Notes within
the meaning of this Section 4.01.

     To the extent lawful, the Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on (i)
overdue principal, at the rate borne by Notes, compounded semiannually; and (ii)
overdue installments of interest (without regard to any applicable grace period)
at the same rate, compounded semiannually.

     SECTION 4.02. Commission Reports. Whether or not required by the rules and
regulations of the Commission, so long as any Notes are outstanding, the Company
will file with the Commission and furnish to the Trustee and the holders of
Notes all quarterly and annual financial information (without exhibits) required
to be contained in a filing with the Commission on Forms 10-Q and 10-K,
including a "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and, with respect to the annual consolidated financial
statements only, a report thereon by the Company's independent auditors. The
Company shall not be required to file any report or other information with the
Commission if the Commission does not permit such filing, although such reports
or other information will be required to be furnished to the Trustee.

     SECTION 4.03. Compliance Certificate. (a) The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company, a
certificate of the principal executive officer, principal financial officer or
principal accounting officer such officer's knowledge of the Company's
compliance with all conditions and covenants under this Indenture (without
regard to any period of grace or requirement of notice provided hereunder).

          (b) The Company shall, so long as any of the Notes are outstanding,
deliver to the Trustee, forthwith upon becoming aware of any Default or Event of
Default, an Officers' Certificate specifying such Default or Event of Default.

     SECTION 4.04. Maintenance of Office or Agency. The Company shall maintain
or cause to be maintained the office or agency required under Section 2.03. The
Company shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency not maintained by the Trustee.
If at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof,
presentations, surrenders, notices and demands with respect to the Notes may be
made or served at the Corporate Trust Office of the Trustee.

                                       16

<PAGE>

          The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designation.

     SECTION 4.05. Continued Existence. Subject to Article V, the Company shall
do or cause to be done all things necessary to preserve and keep in full force
and effect its corporate existence.

     SECTION 4.06. Repurchase Upon Designated Event. Upon the occurrence of a
Designated Event (the date of each such occurrence being the "Designated Event
Date"), the Company shall be required to make an offer (the "Designated Event
Offer") to repurchase all Notes then outstanding at a repurchase price in cash
(the "Designated Event Payment") equal to 100% of the principal amount thereof,
plus accrued and unpaid interest, if any, to, but excluding, the Designated
Event Payment Date (as defined below).

          Notice of a Designated Event shall be mailed by or at the direction of
the Company to the holders of Notes as shown on the Register of such holders
maintained by the Registrar not more than 20 days after the applicable
Designated Event Date at the addresses as shown on the Register of holders
maintained by the Registrar, with a copy to the Trustee and the Paying Agent.
The Designated Event Offer shall remain open until a specified date (the
"Designated Event Offer Termination Date") which is at least 20 Business Days
from the date such notice is mailed. During the period specified in such notice,
holders of Notes may elect to tender their Notes in whole or in part in integral
multiples of $1,000 in exchange for cash. Payment shall be made by the Company
in respect of Notes properly tendered pursuant to this Section on a specified
Business Day (the "Designated Event Payment Date") which shall be no earlier
than five Business Days after the applicable Designated Event Offer Termination
Date and no later than 60 days after the applicable Designated Event. Unless and
until the Trustee shall receive a notice of the occurrence of a Designated
Event, the Trustee may assume without inquiry that none has occurred.

          The notice, which shall govern the terms of the Designated Event
Offer, shall include such disclosures as are required by law and shall state:

          (a) that a Designated Event Offer is being made pursuant to this
Section 4.06 and that all Notes will be accepted for payment;

          (b) the transaction or transactions that constitute the Designated
Event;

          (c) the Designated Event Payment for each Note, the Designated Event
Offer Termination Date and the Designated Event Payment Date;

          (d) that any Note not accepted for payment will continue to accrue
interest in accordance with the terms thereof;

          (e) that, unless the Company defaults on making the Designated Event
Payment, any Note accepted for payment pursuant to the Designated Event Offer
shall cease to accrue interest on the Designated Event Payment Date and no
further interest shall accrue on or after such date;

          (f) that holders electing to have Notes repurchased pursuant to a
Designated Event Offer will be required to surrender their Notes to the Paying
Agent at the address specified in the notice prior to 5:00 p.m., New York City
time, on the Designated Event Offer Termination Date and must complete any form
letter of transmittal proposed by the Company and acceptable to the Trustee and
the Paying Agent;

                                       17

<PAGE>

          (g) that holders of Notes will be entitled to withdraw their election
if the Paying Agent receives, not later than 5:00 p.m., New York City time, on
the Designated Event Offer Termination Date, a facsimile transmission or letter
setting forth the name of the holder, the principal amount of Notes the holder
delivered for purchase, the Note certificate number (if any) and a statement
that such holder is withdrawing his election to have such Notes purchased;

          (h) that holders whose Notes are repurchased only in part will be
issued Notes equal in principal amount to the unpurchased portion of the Notes
surrendered;

          (i) the instructions that holders must follow in order to tender their
Notes; and

          (j) that in the case of a Designated Event Offer Termination Date that
is also an Interest Payment Date, the interest payment, if any, due on such
Interest Payment Date shall be paid to the Person in whose name the Note is
registered at the close of business on the relevant Designated Event Offer
Termination Date.

          On the Designated Event Offer Termination Date the Company shall (i)
accept for payment all Notes or portions thereof properly tendered pursuant to
the Designated Event Offer, (ii) deposit with the Paying Agent money sufficient
to pay the Designated Event Payment with respect to all Notes or portions
thereof so tendered and accepted and (iii) deliver or cause to be delivered to
the Trustee the Notes so accepted together with an Officers' Certificate setting
forth the aggregate principal amount of Notes or portions thereof tendered to
and accepted for payment by the Company. On the Designated Event Payment Date,
the Paying Agent shall mail or deliver to the holders of Notes so accepted, the
Designated Event Payment, and the Trustee shall promptly authenticate and mail
or cause to be transferred by book entry to such holders a new Note equal in
principal amount to any unpurchased portion of the Note surrendered, if any;
provided that such new Notes will be in a principal amount of $1,000 or an
integral multiple thereof. Any Notes not so accepted shall be promptly mailed or
delivered by the Company to the holder thereof.

          In the case of any reclassification, change, consolidation, merger,
combination or sale or conveyance to which Section 12.06 applies, in which the
Common Stock of the Company is 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 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 other property and 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 (which shall comply 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 Notes to cause the Company
to repurchase Notes following a Designated Event, including the applicable
provisions of this Section 4.06 and the definitions of Designated Event, Change
of Control and Termination of Trading, as appropriate, as determined in good
faith by the Company (which determination shall be conclusive and binding), to
make such provision apply to such common stock and the issuer thereof if
different from the Company and Common Stock of the Company (in lieu of the
Company and the Common Stock of the Company).

          The Designated Event Offer shall be made by the Company in compliance
with all applicable provisions of the Exchange Act, and all applicable tender
offer rules promulgated thereunder,

                                       18

<PAGE>

to the extent such laws and regulations are then applicable and shall include
all instructions and materials that the Company shall reasonably deem necessary
to enable such holders of Notes to tender their Notes.

     SECTION 4.07. Appointments to Fill Vacancies in Trustee's Office. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 7.08, a Trustee, so that there
shall at all times be a Trustee hereunder.

     SECTION 4.08. Stay, Extension and Usury Laws. The Company covenants (to the
extent that it may lawfully do so) that it shall not at any time insist upon,
plead or in any manner whatsoever claim or take the benefit or advantage of, any
stay, extension or usury law wherever enacted, now or at any time hereafter
enforced, that may affect the Company's obligation to pay the Notes; and the
Company (to the extent that it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law insofar as such law applies to the Notes,
and covenants that it shall not, by resort to any such law, hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and permit the execution of every such power as though no such law has been
enacted.

     SECTION 4.09. Taxes. 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.

Indenture and the Notes.

                                       21

     SECTION 6.02. Acceleration. If an Event of Default (other than an Event of
Default with respect to the Company specified in clauses (h) and (i) of Section
6.01) 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 Notes, by written notice to the Company
and the Trustee, may declare the unpaid principal of, premium, if any, and
accrued and unpaid interest, if any, on all the Notes to be due and payable.
Upon such declaration such principal amount, premium, if any, and accrued and
unpaid interest, if any, shall become immediately due and payable,
notwithstanding anything contained in this Indenture or the Notes to the
contrary, but subject to the provisions of Article XI hereof. If any Event of
Default with respect to the Company specified in clauses (h) or (i) of Section
6.01 occurs, all unpaid principal of and premium, if any, and accrued and unpaid
interest, if any, on the Notes then outstanding shall become automatically due
and payable subject to the provisions of Article XI hereof, without any
declaration or other act on the part of the Trustee or any holder of Notes.

          The holders of a majority in aggregate principal amount of the then
outstanding Notes by notice to the Trustee may rescind an acceleration of the
Notes and its consequences if all existing Events of Default (other than
nonpayment of principal of or premium, if any, and interest, if any, on the
Notes which has become due solely by virtue of such acceleration) have been
cured or waived and if the rescission would not conflict with any judgment or
decree of any court of competent jurisdiction. No such rescission shall affect
any subsequent 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 or interest on the Notes or to
enforce the performance of any provision of the Notes or this Indenture. The
Trustee may maintain a proceeding even if it does not possess any of the Notes
or does not produce any of them in the proceeding. A delay or omission by the
Trustee or any holder of a Note 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 Notes then outstanding may, on behalf of the
holders of all the Notes, waive an existing Default or Event of Default and its
consequences, except a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on the Notes (other than the
non-payment of principal of and premium, if any, and interest, if any, on the
Notes which has become due solely by virtue of an acceleration which has been
duly rescinded as provided above), or in respect of a covenant or provision of
this Indenture which cannot be modified or amended without the consent of all
holders of Notes. When a Default or Event of Default is waived, it is cured and
stops continuing. No waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereon.

     SECTION 6.05. Control by Majority. The holders of a majority in aggregate
principal amount of the then outstanding Notes 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
Notes or that may involve the Trustee in personal liability; provided that the
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 a Note may not pursue any
remedy with respect to this Indenture or the Notes unless:

                                       22

<PAGE>

               (1) the holder gives to the Trustee notice of a continuing Event
     of Default;

               (2) the holders of at least 25% in principal amount of the then
     outstanding Notes make a request to the Trustee to pursue the remedy;

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

               (4) the Trustee does not comply with the request within 60 days
     after receipt of the request and the offer and, if requested, the provision
     of indemnity; and

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

          A holder of a Note 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. Subject to the
provisions of Article XI hereof, notwithstanding any other provision of this
Indenture, the right of any holder of a Note to receive payment of principal,
premium, if any, and interest, if any, on the Note, on or after the respective
due dates expressed in the Note, 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 Note shall not be impaired or affected
without the consent of the holder of a Note.

     SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified
in Section 6.01(a), (b) or (d) 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 and interest, if any, remaining unpaid on the
Notes and interest, if any, on overdue principal and interest, 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 Notes allowed in
any judicial proceedings relative to the Company, its creditors or its property.
Nothing contained herein shall be deemed to authorize the Trustee to authorize
or consent to or accept or adopt on behalf of any holder of a Note any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any holder thereof, or to authorize the Trustee to vote in respect
of the claim of any holder in any such proceeding.

     SECTION 6.10. Priorities. If the Trustee collects any money pursuant to
this Article VI, 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 Senior Debt to the extent required by Article
XI;

          Third: to holders of Notes for amounts due and unpaid on the Notes for
principal, premium, if any, and interest, if any, ratably, without preference or
priority of any kind, according to the

                                       23

<PAGE>

amounts due and payable on the Notes for principal, premium, if any, and
interest, if any, respectively; and

          Fourth: to the Company.

          The Trustee may fix a special record date and payment date for any
payment to holders of Notes made pursuant to this section. At least 15 days
before any such special record date, the Trustee shall mail to holders of the
Notes a notice that states the special record date, payment date and amount of
such interest to be paid.

     SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as 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, 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 principal amount of the then outstanding Notes.

                                   ARTICLE VII
                                   THE TRUSTEE

          The Trustee hereby accepts the trust imposed upon it by this Indenture
and covenants and agrees to perform the same, as herein expressed. Whether or
not herein expressly so provided, every provision of this Indenture relating to
the conduct or affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Article VII.

     SECTION 7.01. Duties of the Trustee.

          (a) If an Event of Default known to 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 the same degree of care and skill in their exercise
as a prudent Person would exercise or use under the circumstances in the conduct
of his or her own affairs.

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

               (1) The duties of the Trustee shall be determined solely by the
     express provisions of this Indenture and the Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others and no implied covenants or obligations shall be read into this
     Indenture against the Trustee; and

               (2) In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon any statements, certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Indenture. However, the Trustee shall examine the certificates and
     opinions to determine whether or not they conform to the form required by
     this Indenture.

          (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 that:

               (1) This paragraph does not limit the effect of paragraph (b) of
     this Section;

                                       24

<PAGE>

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

               (3) The Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05.

this Indenture that is in any way related to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section 7.01.

          (e) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or incur any financial liability in the performance of any
of its duties or the exercise of any of its rights and powers hereunder, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk of liability is not reasonably assured to
it.

          (f) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree with the Company. Money held in trust by
the Trustee need not be segregated from other funds except to the extent
required by law.

demand, request, direction or notice from the Company shall be sufficient if
signed by Officers of the Company.

respect of the performance of its powers and duties hereunder.

rights or powers vested in it by this Indenture at the request, order or

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.

     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 Notes 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 Notes. It shall not be accountable for the Company's use of the proceeds

and is continuing and if it is known to the Trustee, the Trustee shall mail to
each holder of a Note a notice of the Default or Event of Default within 60 days
after it occurs. A Default or an Event of Default shall not be considered known
to the Trustee unless it is a Default or Event of Default in the payment of
principal or interest when due under Section 6.01(a), (b) or (d) or the Trustee
shall have received notice thereof, in accordance with this Indenture, from the
Company or from the holders of a majority in principal amount of the outstanding
Notes. Except in the case of a Default or Event of Default in payment of
principal of, premium, if any, or interest, if any, on any Note, 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 Notes.

Notes a brief report dated as of such reporting date that complies with TIA

     SECTION 7.07. Compensation and Indemnity. The Company shall pay to the
Trustee from time to time and the Trustee shall be entitled to reasonable

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 the Trustee against any 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 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 Notes 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 and
interest, if any, on Notes. 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 Section 6.01(h) or (i) 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.

                                       27

<PAGE>

          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
principal amount of the then outstanding Notes may remove the Trustee by so
notifying the Trustee and the Company in writing and may appoint a successor
Trustee. The Company may remove the Trustee if:

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

               (2) 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;

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

               (4) the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the holders
of a majority in principal amount of the then outstanding Notes 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, the Company or the
holders of at least 10% in principal amount of the then outstanding Notes may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

          If the Trustee after written request by any holder of a Note 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 Notes. 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.

     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

                                       28

<PAGE>

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.

                                  ARTICLE VIII
                     SATISFACTION AND DISCHARGE OF INDENTURE

     SECTION 8.01. Discharge of Indenture. When (a) the Company delivers to the
Trustee for cancellation all Notes theretofore authenticated (other than any
other Notes which have been destroyed, lost or stolen and in lieu of or in
substitution for which other Notes have been authenticated and delivered) and
not theretofore canceled, or (b) all the Notes not theretofore canceled or
delivered to the Trustee for cancellation have become due and payable or by
their terms will become due and payable within one year, and the Company
deposits with the Trustee, in trust, amounts sufficient to pay at maturity of
all of the Notes (other than any Notes which have been mutilated, destroyed,
lost or stolen and in lieu of or in substitution for which other Notes have been
authenticated and delivered) not theretofore canceled or delivered to the
Trustee for cancellation, including principal and premium, if any, and interest,
if any, due or to become due to such date of maturity, and if 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 Notes, (ii) rights hereunder of holders of Notes to receive
payments of principal of and premium, if any, and interest, if any, on the
Notes, (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 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 compensate the Trustee for any services thereafter reasonably and
properly rendered by the Trustee in connection with this Indenture or the Notes.

     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, notwithstanding the
provisions of Article XI, either directly or through the Paying Agent, to the
holders of the particular Notes for the payment of which such monies have been
deposited with the Trustee, of all sums due and to become due thereon for
principal and interest, if any, and premium, 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 the Trustee) shall, upon the Company's 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, or interest, if any, on Notes and not applied
but remaining unclaimed by the holders thereof for two years after the date upon
which the principal of, premium, if any, or interest on such Notes, as the case
may be, have become due and payable, shall be repaid to the Company by the
Trustee on demand; provided, however, that the Company, or the Trustee at the
request of the Company, shall have first caused notice of such payment to the
Company to be mailed to each holder of a Note entitled thereto no less than 30
days

                                       29

<PAGE>

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 Notes 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 Notes 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 on or
principal of any Note 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.

                                   ARTICLE IX
                                   AMENDMENTS

     SECTION 9.01. Without the Consent of Holders. The Company and the Trustee
may amend this Indenture or the Notes without notice to or the consent of any
holder of a Note for the purposes of:

          (a) curing any ambiguity or correcting or supplementing any defective
or inconsistent provision contained in this Indenture or making any other
changes in the provisions of this Indenture which the Company and the Trustee
may deem necessary or desirable provided such amendment does not materially and
adversely affect the legal rights under the Indenture of the holders of Notes.

          (b) providing for uncertificated Notes in addition to or in place of
certificated Notes;

          (c) evidencing the succession of another Person to the Company and
providing for the assumption by such successor of the covenants and obligations
of the Company thereunder and in the Notes as permitted by Section 5.01;

          (d) providing for conversion rights and/or repurchase rights of
holders of Notes in the event of consolidation, merger or sale of all or
substantially all of the assets of the Company as required to comply with
Sections 5.01 and/or 12.06;

          (e) increasing the Conversion Rate;

          (f) making any changes that would provide the holders of the Notes
with any additional rights or benefits or that does not adversely affect the
legal rights under this Indenture of any such holder; or

          (g) complying with the requirements of the Commission in order to
effect or maintain the qualification of the Indenture under the TIA.

     SECTION 9.02. With the Consent of Holders. Subject to Section 6.07, the
Company and the Trustee may amend this Indenture or the Notes with the written
consent of the holders of at least a majority in principal amount of the then
outstanding Notes (including consents obtained in connection with a tender offer
or exchange offer for Notes).

                                       30

<PAGE>

          Subject to Sections 6.04 and 6.07, the holders of a majority in
principal amount of the Notes then outstanding may also waive compliance in a
particular instance by the Company with any provision of this Indenture or the
Notes.

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

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

          (b) reduce the principal of, or change the fixed maturity of any Note;

          (c) reduce the rate of, or change the time for payment of, interest,
including defaulted interest, if any, on any Note;

          (d) waive a Default or Event of Default in the payment of principal of
or premium, if any, or interest on the Notes (except a rescission of
acceleration of the Notes by the holders of at least a majority in aggregate
principal amount of the Notes then outstanding and a waiver of the payment
default that resulted from such acceleration);

          (e) make the principal of, or premium, if any, or interest on any Note
payable in money other than as provided for herein and in the Notes;

          (f) make any change in the provisions of this Indenture relating to
waivers of past Defaults or Events of Default or the rights of holders of Notes
to receive payments of principal of, premium, if any, or interest or the Notes;

          (g) except as permitted herein (including Section 9.01(a)), reduce the
Conversion Rate or modify the provisions contained herein relating to conversion
of the Notes in a manner adverse to the holders thereof; or

          (h) make any change to the abilities of holders of Notes to enforce
their rights hereunder or the provisions of clauses (a) through (g) of this
Section 9.02.

          In order to amend any provisions of Article XI, holders of at least
75% in aggregate principal amount of Notes then outstanding must consent to such
amendment if such amendment would adversely affect the rights of holders of
Notes.

          To secure a consent of the holders of Notes under this Section, it
shall not be necessary for such holders to approve the particular form of any
proposed amendment or waiver, but it shall be sufficient if such consent
approves the substance thereof.

          After an amendment or waiver under this Article IX becomes effective,
the Company shall mail to holders of Notes a notice briefly describing the
amendment or waiver.

     SECTION 9.03. Compliance with the Trust Indenture Act. Every amendment to
this Indenture or the Notes 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 a Note is a continuing
consent by the holder and every subsequent

                                       31

<PAGE>

holder of a Note or portion of a Note that evidences the same debt as the
consenting holder's Note, even if notation of the consent is not made on any
Note. However, any such holder or subsequent holder may revoke the consent as to
his or her Note or portion of a Note 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
Notes 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 Notes 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 Notes 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 from holders of the
principal amount of Notes required hereunder for such amendment or waiver to be
effective shall have also been given and not revoked within such 90-day period.

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

     SECTION 9.05. Notation on or Exchange of Notes. Notes authenticated and
delivered after the execution of any supplemental indenture pursuant to this
Article IX may, and shall if required by the Trustee, bear a notation in the
form approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Notes 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 Notes without charge to the
holders of the Notes, 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 IX if such amendment
or supplemental indenture does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may, but need
not, sign it. In signing such amendment or supplemental indenture, the Trustee
shall be entitled to 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 inconsistent herewith, and that it will be valid and
binding upon the Company in accordance with its terms.

                                    ARTICLE X
                               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 excludes any provision of the
TIA that may be so modified or excluded, the Indenture provision so modifying or
excluding such provision of the TIA shall be deemed to apply.

     SECTION 10.02. Notices. Any notice or communication by the Company or the
Trustee to the other is duly given if in writing and delivered in person or
mailed by first-class mail, with postage prepaid (registered or certified,
return receipt requested), or sent by facsimile or overnight air couriers
guaranteeing next day delivery, to the other's address as stated in Section
10.10. The Company or the

                                       32

<PAGE>

Trustee by notice to the other may designate additional or different addresses
for subsequent notices or communications.

          All notices and communications (other than those sent to holders of
Notes) shall be deemed to have been duly given at the time delivered by hand, if
personally delivered; five Business Days after being deposited in the mail,
postage prepaid, if mailed; when transmission is confirmed, if transmitted by
facsimile; and the next Business Day after timely delivery to the courier, if
sent by overnight air courier guaranteeing next day delivery. Notwithstanding
the foregoing, all notices to the Trustee shall be effective only upon receipt
by a Trust Officer.

          Any notice or communication to a holder of a Note shall be mailed by
first-class mail, with postage prepaid, to his or her address shown on the
Register kept by the Registrar. Failure to mail a notice or communication to a
holder or any defect in it shall not affect its sufficiency with respect to
other holders.

          If a notice or communication is sent in the manner provided above
within the time prescribed, it is duly given, whether or not the addressee
receives it.

          If the Company sends a notice or communication to holders of Notes, it
shall send a copy to the Trustee and each Agent at the same time.

          All notices or communications shall be in writing.

     SECTION 10.03. Communication by Holders With Other Holders. Holders may
communicate pursuant to TIA Section 312(b) with other holders with respect to

this Indenture, the Company shall furnish to the Trustee:

               (1) an Officers' Certificate in form and substance reasonably
     satisfactory to the Trustee (which shall include the statements set forth
     in Section 10.05) stating that, in the opinion of such person, all
     conditions precedent and covenants, if any, provided for in this Indenture
     relating to the proposed action have been complied with; and

               (2) an Opinion of Counsel in form and substance reasonably
     satisfactory to the Trustee (which shall include the statements set forth
     in Section 10.05) stating that, in the opinion of such counsel, all such
     conditions precedent and covenants have been complied with.

     SECTION 10.05. Statements Required in Certificate or Opinion. Each
certificate or opinion with respect to compliance with a condition or covenant
provided for in this Indenture (other than a certificate provided pursuant to
TIA Section 314(a) (4)) shall include:

               (1) a statement that the person making such certificate or
     opinion has read such covenant or condition;

               (2) a brief statement as to the nature and scope of the

<PAGE>

               (3) a statement that, in the opinion of such person, he or she
     has made such examination or investigation as is necessary to enable him or
     her to express an informed opinion as to whether or not such covenant or
     condition has been complied with; and

               (4) a statement as to whether or not, in the opinion of such
     person, such condition or covenant has been complied with.

          Any Officers' Certificate may be based, insofar as it relates to legal
matters, upon an Opinion of Counsel, unless such Officer knows that the opinion
with respect to the matters upon which his or her certificate may be based as
aforesaid is erroneous. Any Opinion of Counsel may be based, insofar as it
relates to factual matters, upon certificates, statements or opinions of, or
representations by, an officer or officers of the Company, or other Persons or
firms deemed appropriate by such counsel, unless such counsel knows that the
certificates, statements or opinions or representations with respect to the
matters upon which his or her opinion may be based as aforesaid are erroneous.

          Any Officers' Certificate, statement or Opinion of Counsel may be
based, insofar as it relates to accounting matters, upon a certificate or
opinion of or representation by an accountant (who may be an employee of the
Company), or firm of accountants, unless such Officer or counsel, as the case
may be, knows that the certificate or opinion or representation with respect to
the accounting matters upon which his or her certificate, statement or opinion
may be based as aforesaid is erroneous.

     SECTION 10.06. Rules by Trustee and Agents. The Trustee may make reasonable
rules for action by, or a meeting of, holders of Notes. The Registrar or Paying
Agent may make reasonable rules and set reasonable requirements for its

     SECTION 10.07. Legal Holidays. A "Legal Holiday" is a Saturday, a Sunday or
a day on which banking institutions in the City of New York, the city in which
the Corporate Trust Office of the Trustee is located or the City of New York,
New York are not required to be open, and a "Business Day" is any day that is
not a Legal Holiday. If a payment date is a Legal Holiday at a place of payment,
payment may be made at that place on the next succeeding day that is not a Legal
Holiday, and no interest shall accrue for the intervening period. If any date
specified in this Indenture, is a Legal Holiday, then such date shall be the
next succeeding Business Day.

     SECTION 10.08. No Recourse Against Others. No director, officer, employee
or stockholder, as such, of the Company from time to time shall have any
liability for any obligations of the Company under the Notes or this Indenture
or for any claim based on, in respect of, or by reason of such obligations or
their creation. Each holder by accepting a Note waives and releases all such
liability. This waiver and release are part of the consideration for the Notes.
Each of such directors, officers, employees and stockholders is a third party
beneficiary of this Section 10.08.

     SECTION 10.09. Counterparts. This Indenture 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 an original and all of which taken

enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

     SECTION 10.15. Table of Contents, Headings, Etc. The Table of Contents,
Cross-Reference Table and headings of the Articles and Sections of this
Indenture have been inserted for convenience of reference only, are not to be
considered a part hereof and shall in no way modify or restrict any of the terms
or provisions hereof.

                                   ARTICLE XI
                                  SUBORDINATION

     SECTION 11.01. Agreement to Subordinate. The Company agrees, and each
holder of Notes by accepting a Note agrees, that the indebtedness evidenced by
the Note is subordinated in right of payment, to the extent and in the manner
provided in this Article XI, to the prior payment in full in cash of all Senior
Debt (whether outstanding on the Issue Date or thereafter created, incurred,
assumed or guaranteed), and that the subordination is for the benefit of the
holders of Senior Debt. The Company

                                       35

<PAGE>

agrees, and each holder of Notes by accepting a Note agrees, that the
indebtedness evidenced by the Note is equal in right of payment to the Existing
Pari Passu Indebtedness. The Notes shall be "Designated Senior Debt" for
purposes of the indentures governing the Company's Convertible Subordinated
Notes.

     SECTION 11.02. Liquidation; Dissolution; Bankruptcy. Upon any distribution
to creditors of the Company in a liquidation or dissolution of the Company or in
a bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property, in an assignment for the benefit of
creditors or any marshaling of the Company's assets and liabilities:

               (1) holders of Senior Debt shall be entitled to receive payment
     in full of all Obligations due in respect of such Senior Debt (including
     interest, expense reimbursements and indemnities after the commencement of
     any such proceeding at the rate specified in the applicable Senior Debt,
     whether or not such claims are allowed, allowable or enforceable in such
     proceeding and even if disallowed therein) before the holders of the Notes
     shall be entitled to receive any payment with respect to the Notes (except
     that holders of the Notes may receive and retain (A) Permitted Junior
     Securities and (B) payments and other distributions made from any trust
     created pursuant to Section 8.02 hereof); and

               (2) until all Obligations with respect to Senior Debt (as
     provided in clause (1) above) are paid in full, any distribution to which
     holders of Notes would be entitled but for this Article XI shall be made to
     holders of Senior Debt (except that holders of the Notes may receive and
     retain (A) Permitted Junior Securities and (B) payments and other
     distributions made from any trust created pursuant to Section 8.02 hereof),
     as their interests may appear.

     SECTION 11.03. Default on Designated Senior Debt. The Company may not make
any payment or distribution to the Trustee or any holder of Notes in respect of
Obligations with respect to the Notes and may not acquire from the Trustee or
any holder of Notes for cash or property (other than (A) Permitted Junior
Securities and (B) payments and other distributions made from any trust created
pursuant to Section 8.02 hereof) until all principal and other Obligations with
respect to the Senior Debt have been paid in full if:

               (i) a default in the payment of any principal or other
     Obligations in respect of Senior Debt occurs and is continuing beyond any
     applicable grace period in the agreement, indenture or other document
     governing such Senior Debt; or

               (ii) a default, other than a payment default, on Designated
     Senior Debt occurs and is continuing that then permits holders of such
     Designated Senior Debt to accelerate its maturity and the Trustee receives
     a notice of the default (a "Payment Blockage Notice") from a Person who may
     give it pursuant to Section 11.11 hereof.

          If the Trustee receives any Payment Blockage Notice pursuant to
Section 11.03 (ii) hereof, no subsequent Payment Blockage Notice shall be
effective for purposes of such Section unless and until (A) at least 360 days
shall have elapsed since the effectiveness of the immediately prior Payment
Blockage Notice and (B) all scheduled payments of principal, premium, if any,
and interest on the Notes that have come due have been paid in full in cash. No
nonpayment default that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage unless such default shall have been cured or waived
for a period of not less than 180 days.

          The Company may and shall resume payments on and distributions in
respect of the Notes and may acquire them upon the earlier of:

                                       36

<PAGE>

               (1) the date upon which the default is cured or waived, or

               (2) in the case of a nonpayment default referred to in Section
     11.03(ii) hereof, the earlier of the date on which such nonpayment default
     is cured or waived or 179 days after notice is received if the maturity of
     such Designated Senior Debt has not been accelerated,

if this Article XI otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

     SECTION 11.04. Acceleration of Notes. If payment of the Notes is
accelerated because of an Event of Default, the Company shall promptly notify
holders of Senior Debt (or their Representative) of the acceleration.

     SECTION 11.05. When Distribution Must Be Paid Over. In the event that the
Trustee or any holder of Notes receives any payment of any Obligations with
respect to the Notes at a time when the Trustee or such holder of Notes, as
applicable, has actual knowledge that such payment is prohibited by Section
11.03 hereof, then such payment shall be held by the Trustee or holder of Notes
in trust for the benefit of, and shall be paid forthwith over and delivered,
upon written request, to holders of Senior Debt as their interests may appear or
their Representative under the indenture or other agreement (if any) pursuant to
which Senior Debt may have been issued, as their respective interests may
appear, for application to the payment of all Obligations with respect to Senior
Debt remaining unpaid to the extent necessary to pay such Obligations in full in
accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Debt.

          With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article XI, and no implied covenants or obligations with respect
to the holders of Senior Debt shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of holders of Notes or the
Company or any other Person money or assets to which any holders of Senior Debt
shall be entitled by virtue of this Article XI, except if such payment is made
as a result of the willful misconduct or gross negligence of the Trustee.

     SECTION 11.06. Notice by Company. The Company shall promptly notify the
Trustee and the Paying Agent of any facts known to the Company that would cause
a payment of any Obligations with respect to the Notes or the purchase of any
Notes by the Company to violate this Article XI, but failure to give such notice
shall not affect the subordination of the Notes to the Senior Debt as provided
in this Article XI.

     SECTION 11.07. Subrogation. After all Senior Debt is paid in full and until
the Notes are paid in full, holders of Notes shall be subrogated (equally and
ratably with all other indebtedness pari passu with the Notes) to the rights of
holders of Senior Debt to receive distributions applicable to Senior Debt to the
extent that distributions otherwise payable to the holders of Notes have been
applied to the payment of Senior Debt. A distribution made under this Article XI
to holders of Senior Debt that otherwise would have been made to holders of
Notes is not, as between the Company and holders of Notes, a payment by the
Company on the Notes.

     SECTION 11.08. Relative Rights. This Article XI defines the relative rights
of holders of Notes and holders of Senior Debt. Nothing in this Indenture shall:

                                       37

<PAGE>

               (1) impair, as between the Company and holders of Notes, the
     obligation of the Company, which is absolute and unconditional, to pay
     principal of and interest on the Notes in accordance with their terms;

               (2) affect the relative rights of holders of Notes and creditors
     of the Company, other than their rights in relation to holders of Senior
     Debt; or

               (3) prevent the Trustee or any holder of Notes from exercising
     its available remedies upon a Default or Event of Default, subject to the
     rights of holders and owners of Senior Debt to receive distributions and
     payments otherwise payable to holders of Notes.

          If the Company fails because of this Article XI to pay principal of or
interest on a Note on the due date, the failure is still a Default or Event of
Default.

     SECTION 11.09. Subordination May Not Be Impaired by Company. No right of
any holder of Senior Debt to enforce the subordination of the indebtedness
evidenced by the Notes shall be impaired by any act or failure to act by the
Company or any holder of Notes or by the failure of the Company or any such
holder to comply with this Indenture.

     SECTION 11.10. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Debt, the
distribution may be made and the notice given to their Representative.

          Upon any payment or distribution of assets of the Company referred to
in this Article XI, the Trustee and the holders of Notes shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction or
upon any certificate of such Representative or of the liquidating trustee or
agent or other Person making any distribution to the Trustee or to the holders
of Notes for the purpose of ascertaining the Persons entitled to participate in
such distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article XI.

     SECTION 11.11. Rights of Trustee and Paying Agent. Notwithstanding the
provisions of this Article XI or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts that
would prohibit the making of any payment or distribution by the Trustee, and the
Trustee and the Paying Agent may continue to make payments on the Notes, unless
the Trustee shall have received at least two Business Days prior to the date of
such payment or distribution written notice of facts that would cause the
payment of any Obligations with respect to the Notes to violate this Article XI.
Only the Company or a Representative may give the notice.

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

          The Trustee in its individual or any other capacity may hold Senior
Debt with the same rights it would have if it were not Trustee. Any Agent may do
the same with like rights.

     SECTION 11.12. Authorization to Effect Subordination. Each holder of a Note
by the holder's acceptance thereof authorizes and directs the Trustee on the
holder's behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article XI, and appoints the
Trustee to act as the holder's attorney-in-fact for any and all such purposes.
If the Trustee does not file a proper proof of claim or proof of debt in the
form required in any proceeding referred to in Section 6.09 hereof at least 30
days before the expiration of the time to file such claim, the holders of any

                                       38

<PAGE>

Senior Debt or their Representatives are hereby authorized to file an
appropriate claim for and on behalf of the holders of the Notes.

     SECTION 11.13. Amendments. The provisions of this Article XI shall not be
amended or modified without the written consent of the holders of all Senior
Debt.

     SECTION 11.14. Senior Debt Entitled to Rely. The holders of Senior Debt
shall have the right to rely upon this Article XI, and no amendment or
modification of the provisions contained herein shall diminish the rights of
such holders unless such holders shall have agreed in writing thereto.

                                   ARTICLE XII
               CONVERSION OF CONVERTIBLE SENIOR SUBORDINATED NOTES

     SECTION 12.01. Right to Convert. Subject to and upon compliance with the
provisions of this Indenture, each holder of Notes shall have the right, at such
holder's option, at any time on or before the close of business on the last
trading day prior to the Maturity Date (except that, with respect to any Note or
portion thereof subject to a duly completed election for repurchase, such right
shall terminate on or before the close of business on the Designated Event Offer
Termination Date (unless the Company defaults in the payment due upon
repurchase)) to convert the principal amount of any Note 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) equal to the Conversion Rate in
effect at such time, by surrender of the Note so to be converted in whole or in
part in the manner provided in Section 12.02. A holder of Notes is not entitled
to any rights of a holder of Common Stock until such holder of Notes has
converted his or her Notes to Common Stock, and only to the extent such Notes
are deemed to have been converted to Common Stock under this Article XII.

     SECTION 12.02. Exercise of Conversion Privilege; Issuance of Common Stock
on Conversion; No Adjustment for Interest or Dividends. To exercise, in whole or
in part, the conversion privilege with respect to any Note, the holder of such
Note shall surrender such Note, duly endorsed, at an office or agency maintained
by the Company pursuant to Section 4.04, accompanied by the funds, if any,
required by the penultimate paragraph of this Section 12.02, and shall give
written notice of conversion in the form provided on the Notes (or such other
notice which is acceptable to the Company) to the office or agency that the
holder of Notes elects to convert such Note or such portion thereof specified in
said notice. Such notice shall also state the name or names (with address or
addresses) in which the certificate or certificates for shares of Common Stock
which are issuable on such conversion shall be issued, and shall be accompanied
by transfer taxes, if required pursuant to Section 12.07. Each such Note
surrendered for conversion shall, unless the shares issuable on conversion are
to be issued in the same name as the registration of such Note, be duly endorsed
by, or be accompanied by instruments of transfer in form satisfactory to the
Company duly executed by, the holder of Notes or his or her duly authorized
attorney.

          As promptly as practicable after satisfaction of the requirements for
conversion set forth above, the Company shall issue and shall deliver to such
holder at the office or agency maintained by the Company for such purpose
pursuant to Section 4.04, a certificate or certificates for the number of full
shares of Common Stock issuable upon the conversion of such Note or portion
thereof in accordance with the provisions of this Article XII and a check or
cash in respect of any fractional interest in respect of a share of Common Stock
arising upon such conversion, as provided in Section 12.03 (which payment, if
any, shall be paid no later than five Business Days after satisfaction of the
requirements for conversion set forth above). Certificates representing shares
of Common Stock will not be issued or delivered unless all taxes and duties, if
any, payable by the holder have been paid. In case any Note of a denomination of
an integral multiple greater than $1,000 is surrendered for partial conversion,
and subject to Section 2.02, the

                                       39

<PAGE>

Company shall execute, and the Trustee shall authenticate and deliver to the
holder of the Note so surrendered, without charge to him or her, a new Note or
Notes in authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Note.

          Each conversion shall be deemed to have been effected as to any such
Note (or portion thereof) on the date on which the requirements set forth above
in this Section 12.02 have been satisfied as to such Note (or portion thereof),
and the Person in whose name any certificate or certificates for shares of
Common Stock are issuable upon such conversion shall be deemed to have become on
said date the holder of record of the shares represented thereby; provided,
however, that any such surrender on any date when the Company's stock transfer
books are closed shall constitute the Person in whose name the certificates are
to be issued as the record holder thereof for all purposes on the next
succeeding day on which such stock transfer books are open, but such conversion
shall be at the Conversion Rate in effect on the date upon which such Note is
surrendered.

          Any Note or portion thereof surrendered for conversion during the
period from the close of business on the Regular Record Date for any interest
payment through the close of business on the last trading day immediately
preceding such Interest Payment Date shall be accompanied by payment, in funds
acceptable to the Company, of an amount equal to the interest, otherwise payable
on such Interest Payment Date on the principal amount being converted; provided
however, that no such payment need be made if there exists at the time of
conversion a default in the payment of interest on the Notes; and provided,
further, that no such payment need be made if the Notes are surrendered for
conversion on or after the final Regular Record Date. An amount equal to such
payment shall be paid by the Company on such Interest Payment Date to the holder
of such Note at the close of business on such Regular Record Date; provided
however, that if the Company defaults in the payment of interest, if applicable,
on such Interest Payment Date, such amount shall be paid to the Person who made
such required payment. Except as provided above in this Section 12.02, no
adjustment shall be made for interest accrued, if any, on any Note converted or
for dividends on any shares issued upon the conversion of such Note as provided
in this Article XII.

     SECTION 12.03. Cash Payments in Lieu of Fractional Shares. No fractional
shares of Common Stock or scrip representing fractional shares shall be issued
upon conversion of Notes. If more than one Note shall be surrendered for
conversion at one time by the same holder, the number of full shares which shall
be issuable upon conversion shall be computed on the basis of the aggregate
principal amount of the Notes (or specified portions thereof to the extent
permitted hereby) so surrendered for conversion. If any fractional share of
stock otherwise would be issuable upon the conversion of any Note or Notes, the
Company shall make an adjustment therefore in cash based upon the Current Market
Price (as defined in Section 12.05(g)) of the Common Stock on the last trading
day prior to the date of conversion.

     SECTION 12.04. Conversion Rate. The Conversion Rate shall be as specified
in the form of Note attached as Exhibit A hereto, subject to adjustment as
provided in this Article XII.

     SECTION 12.05. Adjustment of Conversion Rate. The Conversion Rate shall be
adjusted from time to time by the Company as follows:

          (a) If the Company shall hereafter pay a dividend or make a
distribution to all holders of the outstanding Common Stock in shares of Common
Stock, the Conversion Rate in effect at the opening of business on the date
following the Record Date fixed for the determination of stockholders entitled
to receive such dividend or other distribution shall be increased by multiplying
the Conversion Rate in effect at the close of business on such Record Date by a
fraction of which the numerator shall be the total number of shares that would
be outstanding immediately following such dividend or other

                                       40
<PAGE>

distribution and the denominator shall be the number of shares of Common Stock
outstanding at the close of business on the Record Date fixed for such
determination, such reduction to become effective immediately after the opening
of business on the day following the Record Date. If any dividend or
distribution of the type described in this Section 12.05(a) is declared but not
so paid or made, the Conversion Rate shall again be adjusted to the Conversion
Rate which would then be in effect if such dividend or distribution had not been
declared.

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

          (c) If the Company shall issue rights or warrants to all or
substantially all holders of its outstanding shares of Common Stock entitling
them to subscribe for or purchase shares of Common Stock (or securities
convertible into Common Stock) for a period expiring 45 days or less from the
date of issuance of such rights or warrants at a price per share (or a
conversion price per share) less than the Current Market Price on the Record
Date fixed for the determination of stockholders entitled to receive such rights
or warrants, the Conversion Rate shall be adjusted so that the same shall equal
the rate determined by multiplying the Conversion Rate in effect at the close of
business on such Record Date by a fraction of which the numerator shall be the
sum of the number of shares of Common Stock outstanding at the close of business
on the Record Date plus the total number of additional shares of Common Stock so
offered for subscription or purchase (or into which the convertible securities
so offered are convertible) and of which the denominator shall be the sum of the
number of shares of Common Stock outstanding at the close of business on the
Record Date plus the number of shares which the aggregate offering price of the
total number of shares so offered (or the aggregate conversion price of the
convertible securities so offered for subscription or purchase, which shall be
determined by multiplying the number of shares of Common Stock issuable upon
conversion of such convertible securities by the conversion price per share of
Common Stock pursuant to the terms of such convertible securities) would
purchase at the Current Market Price as of the business day immediately
preceding the announcement of the issuance of such rights. Such adjustment shall
become effective immediately after the opening of business on the day following
the Record Date fixed for determination of stockholders entitled to receive such
rights or warrants. To the extent that shares of Common Stock (or securities
convertible into Common Stock) are not delivered pursuant to such rights or
warrants, upon the expiration or termination of such rights or warrants the
Conversion Rate shall be readjusted to be the Conversion Rate which would then
be in effect had the adjustments made upon the issuance of such rights or
warrants been made on the basis of delivery of only the number of shares of
Common Stock actually delivered. If such rights or warrants are not so issued,
the Conversion Rate shall again be adjusted to be the Conversion Rate which
would then be in effect if such Record Date fixed for the determination of
stockholders entitled to receive such rights or warrants had not been fixed. In
determining whether any rights or warrants entitle the holders to subscribe for
or purchase shares of Common Stock at less than such Current Market Price, and
in determining the aggregate offering price of such shares of Common Stock,
there shall be taken into account any consideration received for such rights or
warrants, with the value of such consideration, if other than cash, to be
determined in good faith by the Board of Directors, whose determination shall be
conclusive and described in a resolution of the Board of Directors.

          (d) If the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock shares of any class of capital stock of the Company
(other than any dividends or

                                       41

<PAGE>

distributions to which Section 12.05(a) applies) or evidences of its
indebtedness, cash or other assets (including securities, but excluding (i) any
rights or warrants of a type referred to in Section 12.05(c) and (ii) dividends
and distributions paid exclusively in cash pursuant to Section 12.05(e)) (the
foregoing hereinafter in this Section 12.05(d) called the "Distributed
Securities"), then (unless the Company distributes such Distributed Securities
for distribution to the holders of Notes on such dividend or distribution date
(as if each Holder had converted such Note into Common Stock immediately prior
to the record date with respect to such distribution)), in each such case, the
Conversion Rate shall be increased so that the same shall be equal to the rate
determined by multiplying the Conversion Rate in effect immediately prior to the
close of business on the Record Date with respect to such distribution by a
fraction of which the numerator shall be the Current Market Price on such date
and the denominator shall be such Current Market Price less the fair market
value (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and described in a resolution of the Board of
Directors) on such date of the portion of the Distributed Securities applicable
to one share of Common Stock (determined on the basis of the number of shares of
Common Stock outstanding at the close of business on such Record Date), such
reduction to become effective immediately prior to the opening of business on
the day following the Record Date; provided, however, that in the event the then
fair market value (as so determined) of the portion of the Securities so
distributed applicable to one share of Common Stock is equal to or greater than
the Current Market Price on the Record Date, in lieu of the foregoing
adjustment, adequate provision shall be made so that each holder of Notes shall
have the right to receive upon conversion of a Note (or any portion thereof) the
amount of Distributed Securities such holder would have received had such holder
converted such Note (or portion thereof) immediately prior to such Record Date.
If such dividend or distribution is not so paid or made, the Conversion Rate
shall again be adjusted to be the Conversion Rate which would then be in effect
if such dividend or distribution had not been declared. If the Board of
Directors determines the fair market value of any distribution for purposes of
this Section 12.05(c) by reference to the actual or when issued trading market
for any securities comprising all or part of such distribution, it must in doing
so consider the prices in such market over the same period used in computing the
Current Market Price pursuant to Section 12.05(g) to the extent possible.

          Notwithstanding any other provision of this Section 12.05(d) to the
contrary, rights, warrants, evidences of indebtedness, other securities, cash or
other assets (including, without limitation, any rights distributed pursuant to
any stockholder rights plan) shall be deemed not to have been distributed for
purposes of this Section 12.05(d) if the Company makes proper provision so that
each holder of Notes who converts a Note (or any portion thereof) after the
Record Date fixed for determination of stockholders entitled to receive such
distribution shall be entitled to receive upon such conversion, in addition to
the shares of Common Stock issuable upon such conversion, the amount and kind of
such distributions that such holder would have been entitled to receive if such
holder had, immediately prior to such determination date, converted such Note
into Common Stock.

          Notwithstanding the foregoing, if the securities distributed by the
Company to all holders of its Common Stock consist of Capital Stock of, or
similar equity interests in, a Subsidiary or other business unit of the Company
(the "Spinoff Securities"), the Conversion Rate shall be adjusted, unless the
Company makes an equivalent distribution to the holders of the Notes, so that
the same shall be equal to the rate determined by multiplying the Conversion
Rate in effect on the Record Date fixed for the determination of shareholders
entitled to receive such distribution by a fraction, the numerator of which
shall be the sum of (A) the average Closing Price of one share of Common Stock
over the 10 consecutive trading days (the "Spinoff Valuation Period") commencing
on and including the fifth trading day after the date on which ex-dividend
trading commences for such distribution on the Nasdaq National Market or such
other U.S. national or regional exchange or market on which the Common Stock is
then listed or quoted, and (B) the average Closing Price over the Spinoff
Valuation Period of the Spinoff Securities; provided, that if shares of such
Capital Stock or equity interests are not so listed or quoted, the fair market
value as determined in good faith by the Company's Board of Directors, and the
denominator of which

                                       42

<PAGE>

shall be the average Closing Price of one share of Common Stock over the Spinoff
Valuation Period, such adjustment to become effective immediately prior to the
opening of business on the fifteenth Trading Day after the date on which
ex-dividend trading commences; provided, however, that the Company may in lieu
of the foregoing adjustment elect to make adequate provision so that each Holder
of Securities shall have the right to receive upon conversion thereof the amount
of such Spinoff Securities that such Holder of Securities would have received if
such Securities had been converted on the record date with respect to such
distribution.

          For purposes of this Section 12.05(d) and Sections 12.05(a) and (c),
any dividend or distribution to which this Section 12.05(d) is applicable that
also includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock to which Section 12.05(b) applies (or both),
shall be deemed instead to be (1) a dividend or distribution of the evidences of
indebtedness, assets, shares of capital stock, rights or warrants other than
such shares of Common Stock or rights or warrants to which Section 12.05(c)
applies (and any Conversion Rate increases required by this Section 12.05(d)
with respect to such dividend or distribution shall then be made) immediately
followed by (2) a dividend or distribution of such shares of Common Stock or
such rights or warrants (and any further Conversion Rate reduction required by
Sections 12.05(a) and (c) with respect to such dividend or distribution shall
then be made, except that (A) the Record Date of such dividend or distribution
shall be substituted as "the Record Date fixed for the determination of
stockholders entitled to receive such dividend or other distribution", "Record
Date fixed for such determination" and "Record Date" within the meaning of
Section 12.05(a) and as "the Record Date fixed for the determination of
stockholders entitled to receive such rights or warrants", "the Record Date
fixed for the determination of the stockholders entitled to receive such rights
or warrants" and "such Record Date" within the meaning of Section 12.05(c) and
(B) any shares of Common Stock included in such dividend or distribution shall
not be deemed "outstanding at the close of business on the date fixed for such
determination" within the meaning of Section 12.05(a)).

          (e) If the Company shall, by dividend or otherwise, distribute (a
"Triggering Distribution") cash to all holders of its Common Stock (excluding
any cash that is distributed upon a merger or consolidation to which Section
12.06 applies or as part of a distribution referred to in Section 12.05(c)) the
Conversion Rate shall be increased so that the same shall equal the rate
determined by multiplying the Conversion Rate in effect immediately prior to the
close of business on the record date for such Triggering Distribution (a
"Distribution Determination Date") by a fraction (i) the numerator of which
shall be equal to the Current Market Price per share of Common Stock on such
Distribution Determination Date and (ii) the denominator of which shall be equal
to the Current Market Price per share of Common Stock on such Distribution
Determination Date less the amount of such cash dividend or distribution
applicable to one share of Common Stock (determined on the basis of the number
of shares of Common Stock outstanding at the close of business on the
Distribution Determination Date); provided, however, that if the portion of the
cash so distributed applicable to one share of Common Stock is equal to or
greater than the Current Market Price of the Common Stock on the Distribution
Determination Date, in lieu of the foregoing adjustment, adequate provision
shall be made so that each holder of Notes shall have the right to receive upon
conversion of a Note (or any portion thereof) the amount of cash such holder
would have received had such holder converted such Note (or portion thereof)
immediately prior to such Distribution Determination Date. If such dividend or
distribution is not so paid or made, the Conversion Rate shall again be adjusted
to be the Conversion Rate which would then be in effect if such dividend or
distribution had not been declared.

          (f) If a tender or exchange offer made by the Company or any of its
subsidiaries for all or any portion of the Common Stock expires and such tender
or exchange offer (as amended upon the expiration thereof) requires the payment
to stockholders (based on the acceptance (up to any maximum specified in the
terms of the tender or exchange offer) of Purchased Shares (as defined below))
of an

                                       43

<PAGE>

aggregate consideration having a fair market value (as determined in good faith
by the Board of Directors, whose determination shall be conclusive and described
in a resolution of the Board of Directors) that exceeds the Current Market Price
per share of Common Stock on the trading day next succeeding the last date (the
"Expiration Date") tenders or exchanges could have been made pursuant to such
tender or exchange offer (as it may be amended) (the last time at which such
tenders could have been made on the Expiration Date is hereinafter called the
"Expiration Time"), then the Conversion Rate shall be adjusted so that the same
shall equal the price determined by multiplying the Conversion Rate in effect
immediately prior to close of business on the date of the Expiration Time by a
fraction of which the numerator shall be the sum of (A) the fair market value of
the aggregate consideration (the fair market value as determined by the Board of
Directors, whose determination shall be conclusive evidence of such fair market
value and which shall be evidenced by an Officers' Certificate delivered to the
Trustee) payable to shareholders based on the acceptance (up to any maximum
specified in the terms of the tender or exchange offer) of all shares validly
tendered and not withdrawn as of the Expiration Time (the shares deemed so
accepted, up to any such maximum, being referred to as the "Purchased Shares")
and (B) the product of the number of shares of Common Stock outstanding (less
any Purchased Shares and excluding any shares held in the treasury of the
Company) at the Expiration Time and the Closing Price per share of Common Stock
on the trading day next succeeding the Expiration Date and the denominator of
which shall be the product of the number of shares of Common Stock outstanding
(including Purchased Shares but excluding any shares held in the treasury of the
Company) at the Expiration Time multiplied by the Closing Price per share of the
Common Stock on the Trading Day next succeeding the Expiration Date, such
reduction (if any) to become effective immediately prior to the opening of
business on the day following the Expiration Time. If the Company is obligated
to purchase shares pursuant to any such tender offer, but the Company is
permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the Conversion Rate shall again be adjusted to be
the Conversion Rate which would then be in effect if such tender offer had not
been made. If the application of this Section 12.05(f) to any tender offer would
result in an decrease in the Conversion Rate, no adjustment shall be made for
such tender offer under this Section 12.05(f).

          (g) For purposes of this Section 12.05, the following terms shall have
the meaning indicated:

               (1) "Closing Price" with respect to any securities on any day
     means the closing price on such day or, if no such sale takes place on such
     day, the average of the reported high and low prices on such day, in each
     case on the Nasdaq National Market or New York Stock Exchange, as
     applicable, or, if such security is not listed or admitted to trading on
     such national market or exchange, on the principal national securities
     exchange or quotation system on which such security is quoted or listed or
     admitted to trading, or, if not quoted or listed or admitted to trading on
     any national securities exchange or quotation system, the average of the
     high and low prices of such security on the over-the-counter market on the
     day in question as reported by the National Quotation Bureau Incorporated,
     or a similar generally accepted reporting service, or, if not so available,
     in such manner as furnished by any New York Stock Exchange member firm
     selected from time to time by the Board of Directors for that purpose, or a
     price determined in good faith by the Board of Directors, whose
     determination shall be conclusive and described in a resolution of the
     Board of Directors.

               (2) "Current Market Price" means the average of the daily Closing
     Price per share of Common Stock for the 10 consecutive trading days
     immediately prior to the date in question; provided, however, that (1) if
     the "ex" date (as hereinafter defined) for any event (other than the
     issuance or distribution requiring such computation) that requires an
     adjustment to the Conversion Rate pursuant to Sections 12.05(a), (b), (c),
     (d), (e) or (f) occurs during such 10 consecutive trading days, the Closing
     Price for each trading day prior to the "ex" date for such

                                       44

<PAGE>

     other event shall be adjusted by multiplying such Closing Price by the same
     fraction by which the Conversion Rate is so required to be adjusted as a
     result of such other event, (2) if the "ex" date for any event (other than
     the issuance or distribution requiring such computation) that requires an
     adjustment to the Conversion Rate pursuant to Section 12.05(a), (b), (c),
     (d), (e) or (f) occurs on or after the "ex" date for the issuance or
     distribution requiring such computation and prior to the day in question,
     the Closing Rate for each trading day on and after the "ex" date for such
     other event shall be adjusted by multiplying such Closing Rate by the
     reciprocal of the fraction by which the Conversion Rate is so required to
     be adjusted as a result of such other event, and (3) if the "ex" date for
     the issuance or distribution requiring such computation is prior to the day
     in question, after taking into account any adjustment required pursuant to
     clause (1) or (2) of this proviso, the Closing Price for each trading day
     on or after such "ex" date shall be adjusted by adding thereto the amount
     of any cash and the fair market value (as determined by the Board of
     Directors in a manner consistent with any determination of such value for
     purposes of Sections 12.05(d) or (f), whose determination shall be
     conclusive and described in a resolution of the Board of Directors) of the
     evidences of indebtedness, shares of capital stock or assets being
     distributed applicable to one share of Common Stock as of the close of
     business on the day before such "ex" date. For purposes of any computation
     under Section 12.05(f), the Current Market Price on any date shall be
     deemed to be the average of the daily Closing Prices per share of Common
     Stock for such day and the next two succeeding trading days; provided,
     however, that if the "ex" date for any event (other than the tender offer
     requiring such computation) that requires an adjustment to the Conversion
     Rate pursuant to Section 12.05(a), (b), (c), (d), (e) or (f) occurs on or
     after the Expiration Time for the tender or exchange offer requiring such
     computation and prior to the day in question, the Closing Price for each
     trading day on and after the "ex" date for such other event shall be
     adjusted by multiplying such Closing Price by the reciprocal of the
     fraction by which the Conversion Rate is so required to be adjusted as a
     result of such other event. For purposes of this paragraph, the term "ex"
     date, (1) when used with respect to any issuance or distribution, means the
     first date on which the Common Stock trades regular way on the relevant
     exchange or in the relevant market from which the Closing Price was
     obtained without the right to receive such issuance or distribution, (2)
     when used with respect to any subdivision or combination of shares of
     Common Stock, means the first date on which the Common Stock trades regular
     way on such exchange or in such market after the time at which such
     subdivision or combination becomes effective, and (3) when used with
     respect to any tender or exchange offer means the first date on which the
     Common Stock trades regular way on such exchange or in such market after
     the Expiration Time of such offer. Notwithstanding the foregoing, whenever
     successive adjustments to the Conversion Rate are called for pursuant to
     this Section 12.05, such adjustments shall be made to the Current Market
     Price as may be necessary or appropriate to effectuate the intent of this
     Section 12.05 and to avoid unjust or inequitable results as determined in
     good faith by the Board of Directors.

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

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

               (5) "trading day" shall mean (x) if the applicable security is
     listed or admitted for trading on the New York Stock Exchange or another
     national securities exchange, a

                                       45

<PAGE>

     day on which the New York Stock Exchange or another national securities
     exchange is open for business or (y) if the applicable security is quoted
     on the Nasdaq National Market, a day on which trades may be made thereon or
     (z) if the applicable security is not so listed, admitted for trading or
     quoted, any day other than a Saturday or Sunday or a day on which banking
     institutions in the State of New York are authorized or obligated by law or
     executive order to close.

          (h) The Company may make such increases in the Conversion Rate, in
addition to those required by Sections 12.05(a), (b), (c), (d), (e) and (f), as
the Board of Directors considers to be advisable to avoid or diminish any income
tax to holders of Common Stock or rights to purchase Common Stock resulting from
any dividend or distribution of stock (or rights to acquire stock) or from any
event treated as such for income tax purposes.

          The Company from time to time may, to the extent permitted by law and
subject to the applicable rules of the Nasdaq National Market, increase the
Conversion Rate of the Notes by any amount for any period of at least 20 days,
if the Board of Directors has made a determination that such increase would be
in the Company's best interests, which determination shall be conclusive and
described in a resolution of the Board of Directors. The increase in Conversion
Rate shall be irrevocable during this period. Whenever the Conversion Rate is
increased pursuant to the preceding sentence, the Company shall mail to the
holders of Notes at his or her last address appearing on the Register of holders
maintained for that purpose a notice of the increase at least 15 days prior to
the date the increased Conversion Rate takes effect, and such notice shall state
the increased Conversion Rate and the period during which it will be in effect.

          (i) With respect to any rights or warrants (the "Rights") that may be
issued or distributed pursuant to any rights plan that the Company implements
after the date of this Indenture (each a "Rights Plan"), in lieu of any
adjustment required by any other provision of this Section 12.05 upon conversion
of the Notes into Common Stock, to the extent that such Rights Plan is in effect
upon such conversion, the holders of Notes will receive, with respect to the
shares of Common Stock issued upon conversion, the Rights described therein
(whether or not the Rights have separated from the Common Stock at the time of
conversion), subject to the limitations set forth in and in accordance with any
such Rights Plan; provided that if, at the time of conversion, however, the
Rights have separated from the shares of Common Stock in accordance with the
provisions of the Rights Plan so that holders would not be entitled to receive
any rights in respect of the shares of Common Stock issuable upon conversion of
the Notes as a result of the timing of the Conversion Date, the Conversion Rate
will be adjusted as if the Company distributed to all holders of Common Stock
Distributed Securities as provided Section 12.05(d), subject to appropriate
readjustment in the event of the expiration, termination, repurchase or
redemption of the Rights. Any distribution of rights or warrants pursuant to a
Rights Plan complying with the requirements set forth in the immediately
preceding sentence of this paragraph shall not constitute a distribution of
rights or warrants pursuant to this Section 12.05. Other than as specified in
this clause (i), there will not be any adjustment to the Conversion Rate as the
result of the issuance of any Rights, the distribution of separate certificates
representing such Rights, the exercise or redemption of such Rights in
accordance with any Rights Plan or the termination or invalidation of any
Rights.

          (j) No adjustment in the Conversion Rate shall be required unless such
adjustment would require an increase or decrease of at least 1% in such price;
provided, however, that any adjustments which by reason of this Section 12.05(j)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Article XII shall be made
by the Company and shall be made to the nearest cent or to the nearest one
hundredth of a share, as the case may be.

                                       46

<PAGE>

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

          (k) Whenever the Conversion Rate is adjusted as herein provided, the
Company shall promptly file with the Trustee and any Conversion Agent other than
the Trustee an Officers' Certificate setting forth the Conversion Rate after
such adjustment and setting forth a brief statement of the facts requiring such
adjustment. Promptly after delivery of such certificate, the Company shall
prepare a notice of such adjustment of the Conversion Rate setting forth the
adjusted Conversion Rate and the date on which each adjustment becomes effective
and shall mail such notice of such adjustment of the Conversion Rate to each
holder of Notes at his or her last address appearing on the Register of holders
maintained for that purpose within 20 days of the effective date of such
adjustment. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

          (l) In any case in which this Section 12.05 provides that an
adjustment shall become effective immediately after a Record Date for an event,
the Company may defer until the occurrence of such event issuing to the holder
of any Note converted after such Record Date and before the occurrence of such
event the additional shares of Common Stock issuable upon such conversion by
reason of the adjustment required by such event over and above the Common Stock
issuable upon such conversion before giving effect to such adjustment.

          (m) For purposes of this Section 12.05, the number of shares of Common
Stock at any time outstanding shall not include shares held in the treasury of
the Company but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock. The Company shall not pay
any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

     SECTION 12.06. Effect of Recapitalization, Reclassification, Consolidation,
Merger, Sale, Lease or Transfer.

          If any of the following events occur: (i) any reclassification or
change of the outstanding shares of Common Stock (other than a change in par
value, or from par value to no par value, or from no par value to par value, or
as a result of a subdivision or combination), (ii) any consolidation, merger or
combination of the Company with another corporation as a result of which holders
of Common Stock shall be entitled to receive stock, securities or other property
or assets (including cash) with respect to or in exchange for such Common Stock,
or (iii) any sale or conveyance of the properties and assets of the Company as
an entirety or substantially as an entirety to any other corporation as a result
of which holders of Common Stock shall be entitled to receive stock, securities
or other property or assets (including cash) with respect to or in exchange for
such Common Stock, then the Company or the successor or purchasing corporation,
as the case may be, shall execute with the Trustee a supplemental indenture
(which shall comply with the TIA as in force at the date of execution of such
supplemental indenture if such supplemental indenture is then required to so
comply) providing that the Notes shall be convertible into the kind and amount
of shares of stock and other securities or property or assets (including cash)
receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance by a holder of a number of shares of Common
Stock issuable upon conversion of the Notes (assuming, for such purposes, a
sufficient number of authorized shares of Common Stock available to convert all
such Notes) immediately prior to such reclassification, change, consolidation,
merger, combination, sale or conveyance (subject to the right of such holder to
receive the Make Whole Premium (as defined in Section 12.11) upon compliance
with the provisions of such Section) ) assuming such holder of Common Stock did
not exercise his or her rights of election, if any, as to the kind or amount of
securities, cash or other property receivable upon such

                                       47

<PAGE>
consolidation, merger, statutory exchange, sale or conveyance. In the event
holders of Common Stock have the opportunity to elect the form of consideration
to be received in a reclassification, change, consolidation, merger combination,
sale or conveyance, the Company will make adequate provision whereby holders of
the Notes shall have the opportunity, on a timely basis, to determine the form
of consideration into which all of the Notes, treated as a single class, shall
be convertible. Such determination shall be based on the blended, weighted
average of elections made by holders of the Notes who participate in such
determination and shall be subject to any limitations to which all of the
holders of Common Stock are subject to, such as pro rata reductions applicable
to any portion of the consideration payable. Such supplemental indenture shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article XII.

          If, in the case of any such reclassification, change, consolidation,
merger, combination, sale, transfer or statutory exchange of the stock or other
securities and assets receivable thereupon by a holder of shares of Common Stock
includes shares of stock or other securities and assets of a corporation other
than the successor or purchasing corporation, as the case may be, in such
recapitalization, reclassification, change, consolidation, merger, combination,
sale, transfer or statutory exchange, then such supplemental indenture shall
also be executed by such other corporation and shall contain such additional
provisions to protect the interests of the holders of the Notes as the Board of
Directors shall reasonably consider necessary by reason of the foregoing.

          The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Notes at his or her address appearing
on the Register of holders for that purpose within 20 days after execution
thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture.

          The above provisions of this Section 12.06 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

          If this Section 12.06 applies to any event or occurrence, Section
12.05 shall not apply.

     SECTION 12.07. Taxes on Shares Issued. The issue of stock certificates on
conversions of Notes shall be made without charge to the converting holder for
any tax in respect of the issue thereof. The Company shall not, however, be
required to pay any tax which may be payable in respect of any transfer involved
in the issue and delivery of stock in any name other than that of the holder of
any Note converted, and the Company shall not be required to issue or deliver
any such stock certificate unless and until the Person or Persons requesting the
issue thereof shall have paid to the Company the amount of such tax or shall
have established to the reasonable satisfaction of the Company that such tax has
been paid.

     SECTION 12.08. Reservation of Shares; Shares to Be Fully Paid; Listing of
Common Stock. The Company shall provide, free from preemptive rights, out of its
authorized but unissued shares or shares held in treasury, sufficient shares to
provide for the conversion of the Notes from time to time as such Notes are
presented for conversion.

          Before taking any action which would cause an adjustment increasing
the Conversion Rate to a level such that the Conversion Price would be below the
then par value, if any, of the shares of Common Stock issuable upon conversion
of the Notes, the Company shall take all corporate action which may, in the
opinion of its counsel, be necessary in order that the Company may validly and
legally issue shares of such Common Stock at such adjusted Conversion Rate;
provided, however, that no shares of Common Stock shall be required to be issued
at a Conversion Price less than the par value of such Common Stock.

                                       48

<PAGE>

          The Company covenants that all shares of Common Stock issued upon
conversion of Notes will be fully paid and non-assessable by the Company and
free from all taxes, liens and charges with respect to the issue thereof.

          The Company further covenants that as long as the Common Stock is
quoted on the Nasdaq National Market, or its successor, the Company shall cause
all Common Stock issuable upon conversion of the Notes to be eligible for such
quotation in accordance with, and at the times required under, the requirements
of such market, and if at any time the Common Stock becomes listed on the New
York Stock Exchange or any other national securities exchange, the Company shall
cause all Common Stock issuable upon conversion of the Notes to be so listed and
kept listed.

     SECTION 12.09. Responsibility of Trustee. The Trustee shall not at any time
be under any duty of responsibility to any holders of Notes to determine whether
any facts exist which may require any adjustment of the Conversion Price, or
with respect to the nature or extent or calculation of any such adjustment when
made, or with respect to the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same. The Trustee shall not be
accountable with respect to the validity or value (or the kind or amount) of any
shares of Common Stock, or of any securities or property, which may at any time
be issued or delivered upon the conversion of any Note; and the Trustee makes no
representations with respect thereto. Subject to the provisions of Section 7.01,
the Trustee shall not be responsible for any failure of the Company to issue,
transfer or deliver any shares of Common Stock or stock certificates or other
securities or property or cash upon the surrender of any Note for the purpose of
conversion or to comply with any of the duties, responsibilities or covenants of
the Company contained in this Article XII. Without limiting the generality of
the foregoing, the Trustee shall not have any responsibility to determine the
correctness of any provisions contained in any supplemental indenture entered
into pursuant to Section 12.06 relating either to the kind or amount of shares
of stock or securities or property (including cash) receivable by holders of
Notes upon the conversion of their Notes after any event referred to in such
Section 12.06 or to any adjustment to be made with respect thereto, but, subject
to the provisions of Section 7.01, may accept as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, the
Officers' Certificate and Opinion of Counsel (which the Company shall be
obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto.

     SECTION 12.10. Notice to Holders Prior to Certain Actions. If

          (a) the Company declares a dividend (or any other distribution) on its
Common Stock (other than in cash out of retained earnings); or

          (b) the Company authorizes the granting to the holders of its Common
Stock of rights or warrants to subscribe for or purchase any share of any class
of Common Stock or any other rights or warrants; or

          (c) there is any reclassification of the Common Stock (other than a
subdivision or combination of outstanding Common Stock, or a change in par
value, or from par value to no par value, or from no par value to par value), or
of any consolidation or merger to which the Company is a party and for which
approval of any stockholders of the Company is required, or of the sale or
transfer of all or substantially all of the assets of the Company; or

          (d) there is any voluntary or involuntary dissolution, liquidation or
winding-up of the Company;

                                       49

<PAGE>

then the Company shall cause to be filed with the Trustee and to be mailed to
each holder of Notes at his or her address appearing on the Register maintained
for that purpose as promptly as possible but in any event at least 15 days prior
to the applicable date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution or
rights or warrants, or, if a record is not to be taken, the date as of which the
holders of Common Stock of record to be entitled to such dividend, distribution
or rights are to be determined, or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is
expected to become effective or occur, and the date as of which it is expected
that holders of Common Stock of record shall be entitled to exchange their
Common Stock for securities or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such dividend, distribution,
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up.

     SECTION 12.11. Make Whole Premium Upon a Change of Control.

          If there shall have occurred (a) a transaction described in clause (a)
or (b) of the definition of a Change of Control, or (b) a transaction that, but
for the 105% trading price exception contained in clause (x) of the proviso to
such definition would be a Change of Control, the Company shall pay a "Make
Whole Premium" to the Holders of the Notes who surrender their Notes for
conversion during the period beginning 10 trading days before the anticipated
effective date of the Change of Control transaction (the "Effective Date") and
ending at the close of business on the business day immediately preceding the
Designated Event Payment Date by increasing the applicable Conversion Rate for
such Notes by a number of additional shares of Common Stock per $1,000 principal
amount of Notes, as determined by reference to the table below, based on the
Effective Date and the Stock Price on such Effective Date; provided that if the
Stock Price or Effective Date are not set forth on the table: (i) if the actual
Stock Price on the Effective Date is between two Stock Prices on the table or
the actual Effective Date is between two Effective Dates on the table, the Make
Whole Premium will be determined by a straight-line interpolation between the
Make Whole Premiums set forth for the two Stock Prices and the two Effective
Dates on the table based on a 365-day year, as applicable, (ii) if the Stock
Price on the Effective Date equals or exceeds $[ ] per share, subject to
adjustment as set forth herein, no Make Whole Premium will be paid, and (iii) if
the Stock Price on the Effective Date is less than $[ ] per share, subject to
adjustment as set forth herein, no Make Whole Premium will be paid. If Holders
of the Common Stock receive only cash in the Change of Control transaction, the
Stock Price shall be the cash amount paid per share of the Common Stock in
connection with the Change of Control transaction. Otherwise, the Stock Price
shall be equal to the average Closing Prices of the Common Stock for each of the
10 trading days immediately preceding, but not including, the applicable

          The Stock Prices set forth in the first row of the table above (i.e.,
the column headers) will be adjusted as of any date on which the Conversion Rate
of the Securities is adjusted. The adjusted Stock Prices will equal the Stock
Prices applicable immediately prior to such adjustment multiplied by a fraction,
the numerator of which is the Conversion Rate immediately prior to the
adjustment giving rise to the Stock Price adjustment and the denominator of
which is the Conversion Rate as so adjusted. The

                                       50

<PAGE>

number of additional shares set forth in the table above will be adjusted in the
same manner as the Conversion Rate as set forth in Section 12.05 hereof, other
than as a result of an adjustment of the Conversion Rate by adding the Make
Whole Premium as described above.

          For purposes of giving effect to the Make Whole Premium, the
Conversion Price of the Notes following payment of the Make Whole Premium shall
be equal to the product of (a) the Conversion Price immediately prior to payment
of the Make Whole Premium and (b) the fraction obtained by dividing (i) the
Conversion Rate immediately prior to payment of the Make Whole Premium by (ii)
the Conversion Rate immediately after payment of the Make Whole Premium.

          Notwithstanding the foregoing paragraphs, in no event will the total
number of shares of Common Stock issuable upon conversion of a Note exceed
[_____] per $1,000 principal amount of Notes, subject to proportional adjustment
in the same manner as the Conversion Price as set forth in clauses (a) through
(d) of Section 12.05 hereof.

          By delivering the amount of cash and/or the number of shares of Common
Stock issuable on conversion to the Trustee, the Company will be deemed to have
satisfied its obligation to pay the principal amount of the Notes so converted
and its obligation to pay accrued and unpaid interest attributable to the period
from the most recent Interest Payment Date through the date of conversion (which
amount will be deemed paid in full rather than cancelled, extinguished or
forfeited).

                             AMKOR TECHNOLOGY, INC.

            [_______]% CONVERTIBLE SENIOR SUBORDINATED NOTE DUE 2011

          1. INTEREST. Amkor Technology, Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at the
rate per annum shown above. The Company will pay interest semi-annually in
arrears on [______] and [_______] of each year, beginning [_______], 2006.
Interest on the Notes will accrue from the most recent Interest Payment Date to
which interest has been paid or, if no interest has been paid, from [_______],

of twelve 30-day months.

          2. METHOD OF PAYMENT. The Company will pay interest on the Notes
(except defaulted interest) to the Person in whose name each Note is registered
at the close of business on the [_______] or [_______] immediately preceding the
relevant Interest Payment Date (each a "Regular Record Date") (other than with
respect to a Note or portion thereof repurchased in connection with a Designated
Event on a repurchase 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 shall be payable (unless such Note or
portion thereof is converted) to the holder of the Note or portion thereof
repurchased in accordance with the applicable repurchase provisions of the
Indenture). Holder must surrender Notes to a Paying Agent to collect principal
payments. The Company will pay the principal of, premium, if any, and interest
on the Notes at the office or agency of the Company maintained for such purpose,
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Until otherwise designated by the Company,
the Company's office or agency maintained for such purpose will be the principal
Corporate Trust Office of the Trustee (as defined below). However, the Company
may pay principal, premium, if any, and interest by check payable in such money,
and may mail such check to the holders of the Notes at their respective
addresses as set forth in the Register of holders of Notes.

          3. PAYING AGENT AND REGISTRAR. U.S. Bank National Association
(together with any successor Trustee under the Indenture referred to below, the
"Trustee"), will act as Paying Agent and Registrar. The Company may change the

any such capacity.

          4. INDENTURE. The Company issued the Notes under an Indenture dated as
of May [_______], 2006 (the "Indenture") between the Company and the Trustee.
The terms of the Notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code
Sections 77aaa-77bbbb) (the "TIA") as in effect on the Issue Date. The Notes are
subject to, and qualified by, all such terms, certain of which are summarized
hereon, and holders are referred to the Indenture and the TIA for a statement of
such terms. However, to the extent any provision of any Note conflicts with the
express provisions of this Indenture, the provisions of this Indenture shall
govern and be controlling. The Notes are unsecured general obligations of the
Company limited to (except as otherwise provided in the Indenture) up to
$________ in aggregate principal amount. Capitalized terms not defined below
have the same meaning as is given to them in the Indenture. The Company will

<PAGE>

          5. DESIGNATED EVENT. Upon a Designated Event, the Company shall make a
Designated Event Offer to repurchase all outstanding Notes at a price equal to
100% of the aggregate principal amount of the Notes, plus accrued and unpaid
interest to, but excluding, the date of repurchase, such offer to be made as
provided in the Indenture. To accept the Designated Event Offer, the holder
hereof must comply with the terms thereof, including surrendering this Note,
with the "Option of Holder to Elect Repurchase" portion hereof completed, to the
Company, a depositary, if appointed by the Company, or a Paying Agent, at the
address specified in the notice of the Designated Event Offer mailed to holders
as provided in the Indenture, prior to termination of the Designated Event
Offer.

          If there shall occur a Designated Event that constitutes a Change of
Control, the Company shall pay a "Make Whole Premium" in certain circumstances
as described in the Indenture.

          6. SUBORDINATION. The Company's payment of the principal of, premium,
if any, and interest on the Notes is subordinated to the prior payment in full
of the Company's Senior Debt as set forth in the Indenture. Each holder of Notes
by his or her acceptance hereof covenants and agrees that all payments of the
principal of, premium, if any, and interest on the Notes by the Company shall be
subordinated in accordance with the provisions of Article XI of the Indenture,
and each holder of Notes accepts and agrees to be bound by such provisions. The
Company agrees, and each holder of Notes by accepting a Note agrees, that the
indebtedness evidenced by the Note is equal in right of payment to the Existing
Pari Passu Indebtedness.

          7. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. As a condition of transfer, the Registrar and the Trustee may
require a holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company or the Registrar
need not exchange or register the transfer of any Note or portion of a Notes
submitted for repurchase.

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

          9. AMENDMENTS AND WAIVERS. Subject to certain exceptions, the Company
and the Trustee may amend the Indenture or the Notes with the written consent of
the holders of at least a majority in principal amount of the then outstanding
Notes (including consents obtained in connection with tender offer or exchange
offer for Notes) and any existing default may be waived with the consent of the
holders of a majority in principal amount of the then outstanding Notes.

          Without the consent of any holder of a Note, the Indenture or the
Notes may be amended by the Company and the Trustee to: (a) cure any ambiguity
or correct or supplement any defective or inconsistent provision contained in
the Indenture, 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 legal rights under the
Indenture of the holders of Notes; (b) provide for uncertificated Notes in
addition to or in place of certificated Notes; (c) 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 thereunder and in the Notes as
permitted by Section 5.01 of the Indenture; (d) provide for conversion rights
and/or repurchase rights of holders of Notes in the event of consolidation,
merger or sale of all or substantially all of the assets of the Company as
required to comply with Sections 5.01 and/or 12.06 of the Indenture; (e) reduce
the applicable Conversion Price; (f)

                                      A-4

<PAGE>

make any change that would provide any additional rights or benefits to the
holders of Notes or that does not adversely affect the legal rights under the
Indenture of any such holder; or (g) comply with the requirements of the
Commission in order to effect or maintain the qualification of the Indenture
under the TIA.

          Without the consent of each holder affected, an amendment or waiver
may not (with respect to any Notes held by a non-consenting holder): (a) reduce
the principal amount of Notes whose holders must consent to an amendment,
supplement or waiver; (b) reduce the principal of, or premium on, or change the
fixed maturity of any Notes; (c) reduce the rate of or change the time for
payment of interest, including defaulted interest, if any, on any Notes; (d)
waive a Default or Event of Default in the payment of principal of or premium,
if any, or interest, if any, on the Notes (except a rescission of acceleration
of the Notes by the holders of at least a majority in aggregate principal amount
of the Notes and a waiver of the payment default that resulted from such
acceleration); (e) make the principal of, or premium, if any, or interest on any
Note payable in money other than as provided for in the Indenture and in the
Notes; (f) make any change in the provisions of the Indenture relating to
waivers of past Defaults or the rights of holders of Notes to receive payments
of principal of, premium, if any, or interest, if any, on the Notes; (g), except
as permitted by the Indenture (including Section 9.01(a)), increase the
Conversion Price or modify the provisions of the Indenture relating to
conversion of the Notes in a manner adverse to the holders thereof; or (h) make
any change in the foregoing amendment and waiver provisions. In addition, any
amendment to the provisions of Article XI of the Indenture (that relate to
subordination) will require the consent of the holders of at least 75% in
aggregate principal amount of the Notes then outstanding if such amendment would
adversely affect the rights of holders of Notes.

          10. DEFAULTS AND REMEDIES. An Event of Default is: (a) default in
payment of the principal of, or premium, if any, on the Notes, when due at
maturity, upon repurchase, upon acceleration or otherwise, whether or not such
payment is prohibited by the subordination provisions of the Indenture; (b)
default for 30 days or more in payment of any installment of interest on the
Notes, whether or not such payment is prohibited by the subordination provisions
of the Indenture; (c) default by the Company for 60 days or more after notice in
the observance or performance of any other covenants in the Indenture; (d)
default in the payment of the Designated Event Payment in respect of the Notes
on the date therefore, whether or not such payment is prohibited by the
subordination provisions of the Indenture; (e) failure to provide timely notice
of a Designated Event; (f) failure of the Company or any Material Subsidiary to
make any payment at maturity, including any applicable grace period, in respect
of indebtedness for borrowed money of, or guaranteed or assumed by, the Company
or any Material Subsidiary which payment is in an amount in excess of
$20,000,000 and continuance of such failure for 30 days after notice; (g)
default by the Company or any Material Subsidiary with respect to any such
indebtedness, which default results in the acceleration of such indebtedness of
an amount in excess of $20,000,000 without such indebtedness having been paid or
discharged or such acceleration having been cured, waived, rescinded, or
annulled for 30 days after notice; or (h) certain events involving bankruptcy,
insolvency or reorganization of the Company or any Material Subsidiary. If an
Event of Default occurs and is continuing, the Trustee or the holders of at
least 25% in principal amount of the then outstanding Notes may declare the
unpaid principal of, premium, if any, and accrued and unpaid interest, on all
Notes then outstanding to be due and payable immediately, except that in the
case of an Event of Default arising from certain events of bankruptcy,
insolvency, or reorganization with respect to the Company all outstanding Notes
become due and payable without further action or notice. Holders of Notes may
not enforce the Indenture or the Notes except as provided in the Indenture. The
Trustee may require an indemnity satisfactory to it before it enforces the
Indenture or the Notes. Subject to certain limitations, holders of a majority in
principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from holders notice of
any continuing default (except a default in payment of principal, premium, if
any, or interest, if applicable) if it determines that

                                      A-5

<PAGE>

withholding notice is in their interests. The Company must furnish annual
compliance certificates to the Trustee.

          11. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee or any of its
Affiliates, in their individual or any other capacities, may make or continue
loans to or guaranteed by, accept deposits from and perform services for the
Company or its Affiliates and may otherwise deal with the Company or its
Affiliates as if it were not Trustee.

          12. NO RECOURSE AGAINST OTHERS. No director, officer, employee or
stockholder, as such, of the Company shall have any liability for any
obligations of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. Each
holder by accepting a Note waives and releases all such liability. The waiver
and release are part of the consideration for the Notes.

          13. AUTHENTICATION. This Note 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, the registered holder of this Note has the right at any time on
or before the close of business on the last trading day prior to the Maturity
Date (or in case this Note or any portion hereof is subject to a duly completed
election for repurchase, on or before the close of business on the Designated
Event Offer Termination Date (unless the Company defaults in payment due upon
repurchase)) to convert the principal amount hereof, 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 of the Company
("Common Stock") obtained by dividing the principal amount of the Note or
portion thereof to be converted by the conversion price of $[_______] per share,
as adjusted from time to time as provided in the Indenture, including with
respect to the Make Whole Premium (the "Conversion Price"), upon surrender of
this Note to the Company at the office or agency maintained for such purpose
(and at such other offices or agencies designated for such purpose by the
Company), accompanied by written notice of conversion duly executed (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 Note by instruments of
transfer, in form satisfactory to the Company, duly executed by the registered
holder or its duly authorized attorney) 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, also
accompanied by payment, in funds acceptable to the Company, of an amount equal
to the interest, otherwise payable on such Interest Payment Date on the
principal amount of this Note 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 interest accrued hereon or for
dividends on Common Stock delivered on conversion. The right to convert this
Note is subject to the provisions of the Indenture relating to conversion rights
in the case of certain consolidations, mergers, or sales or transfers of
substantially all the Company's assets.

          The Company shall not issue fractional shares or scrip representing
fractions of shares of Common Stock upon any such conversion, but shall make an
adjustment therefore in cash based upon the current market price of the Common
Stock on the last trading day prior to the date of conversion.

Section 2.03 Execution and Authentication.

      Two Officers shall sign the Securities for the Company by manual or
facsimile signature.

      If an Officer whose signature is on a Security no longer holds that office
at the time such Security is authenticated, the Security shall nevertheless be
valid.

      No Security shall be valid until authenticated by the manual signature of
the Trustee. The signature shall be conclusive evidence that such Security has
been authenticated under this Indenture.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Resolutions as permitted by Sections 2.01 and
2.02, in authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 7.01) shall be
fully protected in relying upon, a copy of such Board Resolution, the Officers'
Certificate setting forth the terms of the series and an Opinion of Counsel,
with such Opinion of Counsel stating,

                                      -12-
<PAGE>

            (1) if the form of such Securities has been established by or
      pursuant to Board Resolution as permitted by Section 2.01, that such form
      has been established in conformity with the provisions of this Indenture;

            (2) if the terms of such Securities have been established by or
      pursuant to Board Resolution as permitted by Section 2.02, that such terms
      have been established in conformity with the provisions of this Indenture;
      and

            (3) that such Securities, when authenticated and delivered by the
      Trustee and issued by the Company in the manner and subject to any
      conditions specified in such Opinion of Counsel, will constitute valid and
      legally binding obligations of the Company enforceable in accordance with
      their terms, subject to bankruptcy, insolvency, fraudulent transfer,
      reorganization, moratorium and similar laws of general applicability
      relating to or affecting creditors' rights and to general equity
      principles.

      If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

      Each Security shall be dated the date of its authentication.

      Notwithstanding the provisions of Section 2.02 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 2.02 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

      The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate any Security. An authenticating agent may authenticate any
Security whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

Section 2.04 Registrar, Paying Agent and Conversion Agent.

      The Company shall maintain an office or agency where Securities of any
series may be presented for registration of transfer or for exchange
("Registrar"), an office or agency where Securities of any series may be
presented for payment ("Paying Agent"), and an office or agency where Securities
may be presented for conversion, if applicable (the "Conversion Agent"). The
Registrar shall keep a register of the Securities of any series 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

                                      -13-
<PAGE>

additional conversion agent. The Company may change any Paying Agent, Registrar
or Conversion Agent without notice to any Holder. The Company shall notify the
Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Company fails to appoint or maintain another entity as
Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such. The
Company or any of its Subsidiaries may act as Paying Agent, Registrar or
Conversion Agent.

      The Company initially appoints The Depository Trust Company ("DTC") to act
as Depositary with respect to the Global Securities.

      The Company initially appoints the Trustee to act as the Registrar, Paying
Agent and Conversion Agent and to act as Custodian with respect to the Global
Securities.

Section 2.05 Paying Agent to Hold Money in Trust.

      The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or interest on Securities of any series, and will notify the
Trustee of any default by the Company in 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) shall have no further
liability for the money. If the Company or a Subsidiary acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee shall serve as Paying Agent for
the Securities.

      Section 2.06.Holder Lists.

      The Trustee of any series of Securities shall preserve in as current a
form as is reasonably practicable the most recent list available to it of the
names and addresses of all Holders of such series and shall otherwise comply
with TIA Section 312(a). If the Trustee is not the Registrar of such series, the
Company shall furnish to the Trustee at least seven Business Days before each
interest payment date and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of the Holders of Securities of any series
and the Company shall otherwise comply with TIA Section 312(a).

Section 2.07 Transfer and Exchange

      Upon surrender for registration of transfer of any Security of a series at
the office or agency of the Company in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of like tenor and aggregate
principal amount.

                                      -14-
<PAGE>

      At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

      All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

      Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or its attorney duly authorized in writing.

      No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Sections 2.11, 3.08 or 8.05 not involving any transfer.

      If the Securities of any series (or of any series and specified tenor) are
to be redeemed in part, the Company shall not be required (A) to issue, register
the transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption under Section 3.03 and ending at the
close of business on the day of such mailing, or (B) to register the transfer of
or exchange any Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part.

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

            (1) Each Global Security authenticated under this Indenture shall be
      registered in the name of the Depositary designated for such Global
      Security or a nominee thereof and delivered to such Depositary or a
      nominee thereof or custodian therefor, and each such Global Security shall
      constitute a single Security for all purposes of this Indenture.

            (2) Notwithstanding any other provision in this Indenture, no Global
      Security may be exchanged in whole or in part for Securities registered,
      and no transfer of a Global Security in whole or in part may be
      registered, in the name of any Person other than the Depositary for such
      Global Security or a nominee thereof unless (A) such Depositary (i) has
      notified the Company that it is unwilling or unable to continue as
      Depositary for such Global Security or (ii) has ceased to be a clearing
      agency registered under the Exchange Act, (B) there shall have occurred
      and be continuing an Event of Default with respect to such Global Security
      or (C) there shall exist such circumstances, if any, in addition to or in
      lieu of the foregoing as have been specified for this purpose as
      contemplated by Section 2.02.

                                      -15-
<PAGE>

            (3) Subject to Clause (2) above, any exchange of a Global Security
      for other Securities may be made in whole or in part, and all Securities
      issued in exchange for a Global Security or any portion thereof shall be
      registered in such names as the Depositary for such Global Security shall
      direct.

            (4) Every Security authenticated and delivered upon registration of
      transfer of, or in exchange for or in lieu of, a Global Security or any
      portion thereof, whether pursuant to this Section, Sections 2.08, 2.11 or
      8.06 or otherwise, shall be authenticated and delivered in the form of,
      and shall be, a Global Security, unless such Security is registered in the
      name of a Person other than the Depositary for such Global Security or a
      nominee thereof.

Section 2.08 Replacement Securities.

      If the holder of a Security of any series claims that such Security has
been lost, destroyed or wrongfully taken, the Company shall issue and the
Trustee shall authenticate a replacement Security of that series if the
Trustee's requirements are met. If required by the Trustee or the Company 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, the Company and, if applicable, such authenticating
agent may require. Upon the issuance of any substituted Security, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. In case any Security of a series which has matured
or is about to mature, or has been called for redemption pursuant to Article
III, shall become mutilated or be destroyed, lost or stolen, the Company may,
instead of issuing a substitute Security of that series, 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 authenticating agent such security or
indemnity as may be required by them 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, any paying agent or conversion agent of the
destruction, loss or theft of such Security and of the ownership thereof.

      Every replacement Security of any series 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 of that series
duly issued, authenticated and delivered hereunder.

                                      -16-

Section 2.09 Outstanding Securities.

      The Securities of any series outstanding at any time are all the
Securities of such series authenticated by the Trustee except for those canceled
by it, those delivered to it for cancellation, those reductions in the interest
in a Global Security effected by the Trustee in accordance with the provisions
hereof, and those described in this Section as not outstanding. Except as set
forth in Section 2.09 hereof, a Security of any series does not cease to be
outstanding because the Company or an Affiliate of the Company holds the
Security.

      If a Security of any series is replaced pursuant to Section 2.08 hereof,
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 the principal amount of any Security of any series is considered paid
under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases
to accrue.

      If the Paying Agent (other than the Company, a Subsidiary or an Affiliate
of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Securities of any series payable on that date, then on and after that
date such Securities shall be deemed to be no longer outstanding and shall cease
to accrue interest.

Section 2.10 Treasury Securities.

      In determining whether the Holders of the required principal amount of
Securities of any series have concurred in any direction, waiver or consent,
Securities of that series owned by the Company, or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company, shall be considered as though 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 of that series
that the Trustee knows are so owned shall be so disregarded.

Section 2.11 Temporary Securities.

      (a) Until certificates representing Securities of any series are ready for
delivery, the Company may prepare and the Trustee, upon receipt of an
Authentication Order, shall authenticate temporary Securities of that series.
Temporary Securities shall be substantially in the form of certificated
Securities of that series but may have variations that the Company considers
appropriate for temporary Securities of that series and as shall be reasonably
acceptable to the Trustee. Without unreasonable delay, the Company shall prepare
and the Trustee shall authenticate definitive Securities of any series in
exchange for temporary Securities of that series.

      Holders of temporary Securities of any series shall be entitled to all of
the benefits of this Indenture.

                                      -17-
<PAGE>

      (b) Except for transfers made in accordance with Section 2.07, a Global
Security deposited with the Depositary or with the Trustee as custodian for the
Depositary shall be transferred to the beneficial owners thereof in the form of
certificated Securities of that series in definitive form only if such transfer
complies with Section 2.07 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 (ii) an Event of Default has occurred and is
continuing.

      (c) Any Global Security of any series or interest thereon that is
transferable to the beneficial owners thereof in the form of certificated
Securities of that series in definitive form shall, if held by the Depository,
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 of that series, an equal aggregate principal amount of
Securities of that series of authorized denominations in the form of
certificated Securities of that series 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.

      (d) Prior to any transfer pursuant to Section 2.11(b), the registered
holder of a Global Security of any series 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 of that series.

      (e) The Company will make available to the Trustee a reasonable supply of
certificated Securities of any series in definitive form without interest
coupons.

Section 2.12 Cancellation.

      The Company at any time may deliver Securities of any series to the
Trustee for cancellation. The Registrar and Paying Agent shall forward to the
Trustee any Securities of any series surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else shall cancel
Securities of any series surrendered for registration of transfer, exchange,
payment, replacement or cancellation and shall destroy canceled Securities of
any series (subject to the record retention requirement of the Exchange Act).
Certification of the destruction of all canceled Securities shall be delivered
to the Company. The Company may not issue new Securities of any series to
replace Securities of such series that it has paid or that have been delivered
to the Trustee for cancellation.

Section 2.13 Defaulted Interest.

      If the Company defaults in a payment of interest on Securities of any
series, it shall pay the defaulted interest in any lawful manner plus, to the
extent lawful, interest payable on the defaulted interest, to the Persons who
are Holders of such security on a subsequent special record date. The Company
shall notify the Trustee in writing of the amount of defaulted interest proposed
to be paid on each Security and the date of the proposed payment. The Company
shall fix or cause to be fixed

                                      -18-
<PAGE>

each such special record date and payment date, provided that no such special
record date shall be less than 10 days prior to the related payment date for
such defaulted interest. At least 15 days before the special record date, the
Company (or, upon the written request of the Company, the Trustee in the name
and at the expense of the Company) shall mail or cause to be mailed to Holders a
notice that states the special record date, the related payment date and the
amount of such interest to be paid.

                                   ARTICLE 3
                            REDEMPTION AND PREPAYMENT

Section 3.01 Applicability of Article.

      Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 2.02 for such Securities) in accordance
with this Article.

Section 3.02 Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution or in another manner specified as contemplated by Section
2.02 for such Securities. In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 45
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

Section 3.03 Selection by Trustee of Securities to Be Redeemed.

      If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 45 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by lot, or in the Trustee's discretion, on
a pro-rata basis, provided that the unredeemed portion of the principal amount
of any Security shall be in an authorized denomination (which shall not be less
than the minimum authorized denomination) for such Security. If less than all
the Securities of such series and of a specified tenor are to be redeemed
(unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 30 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
and specified tenor not previously called for redemption in accordance with the
preceding sentence.

                                      -19-
<PAGE>

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

      The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption as aforesaid and, in case of any Securities selected for
partial redemption as aforesaid, the principal amount thereof to be redeemed.

      The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

      For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.

Section 3.04 Notice of Redemption.

      At least 15 days but not more than 60 days before a Redemption Date, the
Company shall mail by first class mail a notice of redemption to each holder
whose Securities are to be redeemed.

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

                        (1) the Redemption Date;

                        (2) the Redemption Price;

                        (3) if any Security of any series is being redeemed in
part, the portion of the principal amount of such Security to be redeemed and
that, after the Redemption Date, upon surrender of such Security, a new Security
or Securities of the same series in principal amount equal to the unredeemed
portion will be issued in the name of the holder thereof;

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

                        (5) that interest on Securities called for redemption
and for which funds have been set apart for payment, ceases to accrue on and
after the Redemption Date (unless the Company defaults in the payment of the
Redemption Price or the Paying Agent is prohibited from making such payment
pursuant to the terms of this Indenture);

                                      -20-
<PAGE>

                        (6) the paragraph of the Securities pursuant to which
the Securities called for redemption are being redeemed;

                        (7) the aggregate principal amount of Securities of that
series (if less than all) that are being redeemed;

                        (8) the CUSIP number of the Securities (provided that
the disclaimer permitted by Section 2.14 may be made);

                        (9) the name and address of the Paying Agent; and

                        (10) that in the case of Securities or portions thereof
called for redemption on a date that is also an Interest Payment Date, the
interest payment, due on such date shall be paid to the Person in whose name the
Security is registered at the close of business on the relevant Regular Record
Date.

      The notice if mailed in the manner herein provided shall be conclusively
presumed to have been given, whether or not the holder receives such notice. In
any case, failure to give such notice by mail or any defect in the notice to the
holder of any Security designated for redemption as a whole or in part shall not
affect the validity of the proceedings for the redemption of any Security of
that series.

      At the Company's request, the Trustee shall give notice of redemption in
the Company's name and at its expense.

Section 3.05 Deposit of Redemption Price.

      On or before the Redemption Date, the Company shall deposit with the
Trustee or with the Paying Agent money in immediately available funds sufficient
to pay the Redemption Price of and accrued interest on all Securities to be
redeemed on that date. The Trustee or the Paying Agent shall promptly return to
the Company any money not required for that purpose.

      On and after the Redemption Date, unless the Company shall default in the
payment of the Redemption Price, interest will cease to accrue on the principal
amount of the Securities or portions thereof called for redemption and for which
funds have been set apart for payment and such Securities, or portions thereof,
shall cease after the close of business on the Business Day immediately
preceding the Redemption Date to be convertible into Common Stock and, except as
provided in this Section 3.05 and 8.04, such Securities, or portions thereof,
shall not be entitled to any benefit or security under this Indenture, and
the holders thereof shall have no right in respect of such Securities, or
portions thereof, except the right to receive the Redemption price thereof
and unpaid interest, to (but excluding) the Redemption Date. In the case of
Securities or portions thereof redeemed on a Redemption Date

                                      -21-
<PAGE>

which is also an Interest Payment Date, the interest payment due on such
Interest Payment Date shall be paid to the Person in whose name the Security is
registered at the close of business on the relevant Regular Record Date.

Section 3.06 Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 2.02, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 3.07.

      If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

Section 3.07 Securities Redeemed in Part.

      Upon surrender of a Security that is redeemed in part only, the Company
shall issue and the Trustee shall authenticate and deliver to the holder of a
Security a new Security of the same series equal in principal amount to the
unredeemed portion of the Security surrendered, at the expense of the Company,
except as specified in Section 2.07.

Section 4.01 Payment of Securities.

      The Company covenants and agrees for the benefit of each series of
Securities that it will pay or cause to be paid the principal of, premium, if
any, and interest on the Securities of that series in accordance with the terms
of the Securities of such series.

Section 4.02 Maintenance of Office or Agency.

      The Company shall maintain or cause to be maintained for any series of
Securities in The Borough of Manhattan, The City of New York, an office or
agency (which may be an office of the Trustee or an Affiliate of the Trustee,
Registrar or co-registrar) where Securities of any series may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Securities and this Indenture may be served.
The Company shall give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

      The Company may also from time to time designate one or more other offices
or agencies where Securities of any series may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in The
Borough of Manhattan, The City of New York for such purposes. The Company shall
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

      The Company hereby designates the Corporate Trust Office of the Trustee as
one such office or agency of the Company in accordance with Section 2.03.

      (a) The Company shall deliver to the Trustee, within 90 days after the end
of each fiscal year, an Officers' Certificate stating that a review of the
activities of the Company and its Subsidiaries during the preceding fiscal year
has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to the best of his or her knowledge the Company

this Indenture and is not in default in the performance or observance of any of
the terms, provisions and conditions of this Indenture (or, if a Default or
Event of Default shall have occurred, describing all such Defaults or Events of
Default of which he or she may have knowledge and what action the Company is
taking or proposes to take with respect thereto) and that to the best of his or
her knowledge no event has occurred and remains in existence by reason of which
payments on account of the principal of or interest, if any, on the Securities
is prohibited or if such event has occurred, a description of the event and what
action the Company is taking or proposes to take with respect thereto.

      (b) The Company shall, so long as any of the Securities are outstanding,
deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officers' Certificate specifying such Default or Event
of Default and what action the Company is taking or proposes to take with
respect thereto.

      Any failure of the Company to take any action within a period of time
explicitly or implicitly required by this Section 4.04 or Section 4.03 should be
deemed cured upon the Company's taking such action.

Section 4.04 Taxes.

      The Company shall pay, and shall cause each of its Subsidiaries to pay,
prior to delinquency, all material taxes, assessments, and governmental levies
except such as are contested in good faith and by appropriate proceedings or

to the Holders of the Securities.

Section 4.05 Stay, Extension and Usury Laws.

      The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company hereby expressly waives all
benefit or advantage of any such law, and covenants that it shall not, by resort
to any such law, hinder, delay or impede the execution of any power herein
granted to the Trustee, but shall suffer and permit the execution of every such
power as though no such law has been enacted.

Section 4.06 Corporate Existence.

      Subject to Article 5 hereof, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i) its corporate
existence, and the corporate, partnership or other existence of each of its
Subsidiaries, in accordance with the respective organizational documents (as the
same may be amended from time to time) of the Company or any such Subsidiary and
(ii) the rights (charter and statutory), licenses and franchises of the Company
and its Subsidiaries; provided, however, that the Company shall not be required
to preserve any such right, license or franchise, or the corporate, partnership
or other existence of any of its Subsidiaries, if the Board of Directors shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and its Subsidiaries, taken as a whole, and that the
loss thereof is not adverse in any material respect to the Holders of the
Securities.

Section 4.07 Money for Securities Payments To Be Held in Trust.

      If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it will, on or prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

      The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

      The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

                                      -25-

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for a period
ending on the earlier of the date that is ten Business Days prior to the date
such money would escheat to the State or two years after such principal, premium
or interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in each Place of Payment, notice that
such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

Section 4.08 Taxes.

      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 Reports by Company.

      The Company shall file with the Trustee and the Commission, and transmit
to Holders, such information, documents and other reports, and such summaries
thereof, as may be required pursuant to the Trust Indenture Act at the times and
in the manner provided pursuant to the Trust Indenture Act; provided that any
such information, documents or reports required to be filed with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the
Trustee within 15 days after the same is so required to be filed with the
Commission.

Section 4.10 Waiver of Certain Covenants.

      Except as otherwise specified as contemplated by Section 2.02 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Sections 2.02(19),
4.08 or 8.01(g) for the benefit of the Holders of such series if before the time
for such compliance the Holders of at least a majority in principal amount of
the Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until

                                      -26-
<PAGE>

such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

Section 5.01 Merger, Consolidation, or Sale of Assets.

      The Company shall not, directly or indirectly, consolidate or merge with
or into another Person (whether or not the Company is the surviving corporation)
or sell, assign, transfer, convey or otherwise dispose of all or substantially
all of its properties or assets, in one or more related transactions, to another
Person, unless (i) the Company is the surviving corporation or the Person formed
by or surviving any such consolidation or merger (if other than the Company) or
to which such sale, assignment, transfer, conveyance or other disposition shall
have been made is a corporation organized or existing under the laws of the
United States, any state thereof or the District of Columbia, (ii) the Person
formed by or surviving any such consolidation or merger (if other than the
Company) or the Person to which such sale, assignment, transfer, conveyance or
other disposition shall have been made assumes all the obligations of the
Company under the Securities and this Indenture pursuant to a supplemental
indenture in a form reasonably satisfactory to the Trustee, (iii) immediately
after such transaction no Default or Event of Default exists, and (iv) the
Company shall have delivered to the Trustee an Officer's Certificate stating
that such consolidation, merger, sale, assignment, transfer, conveyance or other
disposition complies with this Indenture. In addition, the Company shall not,
directly or indirectly, lease all or substantially all of its properties or
assets, in one or more related transactions, to any other Person. The provisions
of this Section 5.01 shall not be applicable to a sale, assignment, transfer,
conveyance or other disposition of assets by the Company to any of its
Subsidiaries.

      Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of the Company in accordance with Section 5.01 hereof, the successor corporation
formed by such consolidation or into or with which the Company is merged or to
which such sale, assignment, transfer, lease, conveyance or other disposition is
made shall succeed to, and be substituted for (so that from and after the date
of such consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to the "Company" shall refer instead to
the successor corporation and not to the Company), and may exercise every right
and power of the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein; provided, however, that
the predecessor Company shall not be relieved from the obligation to pay the
principal of and interest on the Securities except in the case of a sale of all
of the Company's assets that meets the requirements of Section 5.01 hereof.

                              DEFAULTS AND REMEDIES

Section 6.01 Events of Default.

      An "Event of Default" occurs if:

      (a) the Company defaults in the payment when due of interest on Securities
of any series and such default continues for a period of 30 days;

      (b) the Company defaults in the payment when due of principal of or
premium, if any, on the Securities when the same becomes due and payable at
maturity, upon redemption (including in connection with an offer to purchase) or
otherwise;

      (c) the Company defaults in the deposit of any sinking fund payment, when
and as due by the terms of a Security of that series.

      (d) the Company fails to observe or perform any other covenant,
representation, warranty or other agreement in this Indenture (other than a
covenant or warranty which has expressly been included in the indenture solely
for the benefit of series of Securities other than that series) for 60 days
after notice to the Company by the Trustee or the Holders of at least 25% in
aggregate principal amount of the Securities of that series then outstanding
voting as a single class;

      (e) within the meaning of Bankruptcy Law, the Company [or any of its
Significant Subsidiaries or any group of Subsidiaries that, taken as a whole,
would constitute a Significant Subsidiary]:

            (i) commences a voluntary case,

            (ii) consents to the entry of an order for relief against it in an
      involuntary case,

            (iii) consents to the appointment of a custodian of it or for all or
      substantially all of its property,

            (iv) makes a general assignment for the benefit of its creditors, or

            (v) generally is not paying its debts as they become due;

      (f) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that:

            (i) is for relief against the Company [or any of its Significant
      Subsidiaries or any group of Subsidiaries that, taken as a whole, would
      constitute a Significant Subsidiary] in an involuntary case;

                                      -28-
<PAGE>

            (ii) appoints a custodian of the Company [or any of its Significant
      Subsidiaries or any group of Subsidiaries that, taken as a whole, would
      constitute a Significant Subsidiary] or for all or substantially all of
      the property of the Company [or any of its Significant Subsidiaries or any
      group of Subsidiaries that, taken as a whole, would constitute a
      Significant Subsidiary]; or

            (iii) orders the liquidation of the Company [or any of its
      Significant Subsidiaries or any group of Subsidiaries that, taken as a
      whole, would constitute a Significant Subsidiary];

and the order or decree remains unstayed and in effect for 60 consecutive days,
or

      (g) any other Event of Default provided with respect to Securities of that
series in the Board Resolution, supplemental indenture or Officers' Certificate
establishing that series.

Section 6.02 Acceleration.

      Unless the Board Resolution, supplemental indenture or Officers'
Certificate establishing such series provides otherwise, if any Event of Default
(other than an Event of Default specified in clause (e) or (f) of Section 6.01
hereof with respect to the Company, [any Significant Subsidiary or any group of
Significant Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary]) with respect to any series of securities at the time outstanding
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Securities of that series may declare
the principal amount of all the Securities of that series (or, if any Securities
of that series are Original Issue Discount Securities, such portion of the
principal amount of such Securities as may be specified by the terms thereof) to
be due and payable immediately. Upon any such declaration, the principal amount
of the Securities of that series shall become due and payable immediately.
Notwithstanding the foregoing, if an Event of Default specified in clause (e) or
(f) of Section 6.01 hereof with respect to any series of securities at the time
outstanding occurs with respect to the Company, [any of its Significant
Subsidiaries or any group of Subsidiaries that, taken as a whole, would
constitute a Significant Subsidiary,] all outstanding principal amount of the
Securities of that series (or, if any Securities of that series are Original
Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms hereof) shall be due and payable
immediately without further action or notice. The Holders of a majority in
aggregate principal amount of the then outstanding Securities of that series by
written notice to the Trustee may on behalf of all of the Holders rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default (except nonpayment of
principal, interest or premium that has become due solely because of the
acceleration) have been cured or waived.

Section 6.03 Other Remedies.

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

                                      -29-
<PAGE>

      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 accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

      Holders of not less than a majority in aggregate principal amount of the
then outstanding Securities of any series by notice to the Trustee may on behalf
of the Holders of all of the Securities of such series waive an existing Default
or Event of Default and its consequences hereunder, except a continuing Default
or Event of Default in the payment of the principal of, premium or interest on,
the Securities (including in connection with an offer to purchase) (provided,
however, that the Holders of a majority in aggregate principal amount of the
then outstanding Securities of such series may rescind an acceleration and its
consequences, including any related payment default that resulted from such
acceleration). Upon any such waiver, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

      Holders of a majority in principal amount of the then outstanding
Securities of any series may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it relating to the Securities of that series.
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 of that series or that may involve the
Trustee in personal liability.

Section 6.06 Limitation on Suits.

      No Holder of any Security of any series may pursue a remedy with respect
to this Indenture or the Securities of that series unless:

      (a) the Holder of a Security gives to the Trustee written notice of a
continuing Event of Default with respect to the Securities of that series;

      (b) the Holders of at least 25% in principal amount of the then
outstanding Securities of that series make a written request to the Trustee to
pursue the remedy;

      (c) such Holder of a Security or Holders of Securities offer and, if
requested, provide to the Trustee indemnity satisfactory to the Trustee against
any loss, liability or expense;

      (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

                                      -30-
<PAGE>

      (e) during such 60-day period the Holders of a majority in principal
amount of the then outstanding Securities of that series do not give the Trustee
a direction inconsistent with the request.

      A Holder of a Security of any series may not use this Indenture to
prejudice the rights of another Holder of a Security or to obtain a preference
or priority over another Holder of a Security of that series.

Section 6.07 Rights of Holders of Securities to Receive Payment.

      Notwithstanding any other provision of this Indenture, the right of any
Holder of a Security to receive payment of principal, premium and interest on
the Security, on or after the respective due dates expressed in the Security

impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

      If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing with respect to a series of Securities, the Trustee is authorized to
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount of principal of, premium and interest remaining
unpaid on the Securities of that series and interest on overdue principal and,

Holders of the Securities allowed in any judicial proceedings relative to the

paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder

                                      -31-

Securities of any series, the Trustee shall exercise such of the rights and

      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.

      determine whether or not they conform to the requirements of this
      Indenture.

Default specified in Section 6.01(e) or (f) hereof 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.

the extent applicable.

trust hereby created by so notifying the Company. The Holders of a majority in

Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Securities may appoint
a successor Trustee to replace the successor Trustee appointed by the Company.

retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of at least 10% in principal amount of the then outstanding
Securities of such series may petition any court of competent jurisdiction for
the appointment of a successor Trustee.

      If the Trustee, after written request by any Holder 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.

                                      -36-

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. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, provided all sums owing to the Trustee
hereunder have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee.

in uncertificated form;

      (e) to add to, change or eliminate any of the provisions of this Indenture

Section 8.02 With Consent of Holders of Securities.

      Subject to Section 6.07, the Company and the Trustee may amend this
Indenture or the Securities or enter into one or more indentures supplement
hereto with the written consent of the holders of at least a majority in
principal amount of the then outstanding Securities of such series (including
consents obtained in connection with a tender offer or exchange offer for
Securities of that series).

      Subject to Sections 6.04 and 6.07, the holders of a majority in principal
amount of the Securities then outstanding may also waive compliance in a
particular instance by the Company with any provision of this Indenture or the
Securities of any series.

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

      (a) change the Stated Maturity of the principal of, or any installment of
principal of or interest on, any Security, or reduce the principal amount
thereof or the rate of interest thereon or any premium payable upon the
redemption thereof, or reduce the amount of the principal of an Original Issue
Discount Security or any other Security which would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 6.02, or
change any Place of Payment where, or the coin or currency in which, any
Security or any premium or interest thereon is payable, or impair the right to
institute suit for the enforcement of any such payment on or after the Stated
Maturity thereof (or, in the case of redemption, on or after the Redemption
Date), or modify the provisions of this Indenture with respect to the
subordination of such series of Securities in a manner adverse to the holders of
Securities of such series, or, in the case of Securities of any series that are
convertible into Securities or other securities of the Company, adversely affect
the right of holders to convert any of the Securities of such series other than
as provided in or pursuant to this Indenture;

      (b) reduce the percentage in principal amount of the outstanding
Securities of any series, the consent of whose holders is required for any such
supplemental indenture, or the consent of whose holders is required for any
waiver (of compliance with certain provisions of this Indenture or certain
defaults hereunder and their consequences) provided for in this Indenture; or

      (c) modify any of the provisions of this Section, Section 4.09 or Section
6.04, except to increase any such percentage or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent of
the holder of each Outstanding Security affected thereby; provided, however,
that this clause shall not be deemed to require the consent of any holder with
respect to changes in the references to "the Trustee" and concomitant changes in
this Section and Section 4.09, or the deletion of this proviso, in accordance
with the requirements of Sections 7.08 and 9.01(h).

      A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with

                                      -39-
<PAGE>

respect to such covenant or other provision, shall be deemed not to affect the
rights under this Indenture of the Holders of Securities of any other series.

      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
proposed amendment or waiver, but it shall be sufficient if such consent
approves the substance thereof.

      After an amendment or waiver under this Section becomes effective, the
Company shall mail to holders of Securities of such series affected by the
amendment or waiver a notice briefly describing the amendment or waiver.

      In order to amend any provisions of Article XI, holders of at least 75% in
aggregate principal amount of Securities of any series then outstanding must
consent to such amendment if such amendment would adversely affect the rights of
holders of Securities of such series.

Section 8.03 Compliance with Trust Indenture Act.

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

Section 8.04 Revocation and Effect of Consents.

      Until an amendment, supplement or waiver becomes effective, a consent to
it by a Holder of a Security of any series is a continuing consent by the Holder
and every subsequent Holder of a Security or portion of a Security 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 a Security
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 of any series 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 of such series 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 from Holders of the principal amount of Securities of such
series required hereunder for such amendment or waiver to be effective shall
have also been given and not revoked within such 90-day period.

      After an amendment, supplement or waiver becomes effective it shall bind
every Holder of a Security of that series, unless it is of the type described in
clauses (a) through (d) of Section 9.02. In such case, the amendment or waiver
shall bind each Holder of a Security who has consented to it and

                                      -40-
<PAGE>

every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder's Security.

Section 8.05 Notation on or Exchange of Securities.

      Securities of any series authenticated and delivered after the execution
of any supplemental indenture pursuant to this Article VIII 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 of any series 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 of such series without charge to
the Holders of the Securities of such series, except as specified in Section
2.07.

Section 8.06 Effect of Supplemental Indentures.

      Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

Section 8.07 Trustee Protected.

      The Trustee shall sign any amendment or supplemental indenture authorized
pursuant to this Article VIII if such amendment or supplemental indenture does
not adversely affect the rights, duties, liabilities or immunities of the
Trustee. If it does, the Trustee may, but need not, sign it. In signing such
amendment or supplemental indenture, the Trustee shall be entitled to receive,
and shall be fully protected in relying upon, an Officers' Certificate and an

Section 11.02 Defeasance and Discharge.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 11.04 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by such
Securities and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated
or discharged hereunder:

            (1) the rights of Holders of such Securities to receive, solely from
      the trust fund described in Section 11.04 and as more fully set forth in
      such Section, payments in respect of the principal of and any premium and
      interest on such Securities when payments are due,

Securities.

Section 11.03 Covenant Defeasance.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be,

            (1) the Company shall be released from its obligations under Section
      4.08 and any covenants provided pursuant to Sections 2.02(19), 6.01(d) or
      6.01(g) or for the benefit of the Holders of such Securities and

            (2) the occurrence of any event specified in Section 6.01(d) (with
      respect to any of Section 4.08 and any such covenants provided pursuant to
      Section 2.02(19), 6.01(d) or 6.01(g) shall be deemed not to be or result
      in an Event of Default,

in each case with respect to such Securities or any series of Securities as
provided in this Section on and after the date the conditions set forth in
Section 11.04 are satisfied (hereinafter called "Covenant Defeasance"). For this
purpose, such Covenant Defeasance means that, with respect to such Securities,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such specified Section (to
the extent so specified in the case

                                      -47-

elsewhere herein to any such Section or by reason of any reference in any such
Section to any other provision herein or in any other document, but the
remainder of this Indenture and such Securities shall be unaffected thereby.

Section 11.04 Conditions to Defeasance or Covenant Defeasance.

      The following shall be the conditions to the application of Section 11.02
or Section 11.03 to any Securities or any series of Securities, as the case may

            (1) The Company shall irrevocably have deposited or caused to be
      deposited with the Trustee (or another trustee which satisfies the
      requirements contemplated by Section 7.10 and agrees to comply with the
      provisions of this Article applicable to it) as trust funds in trust for
      the purpose of making the following payments, specifically pledged as
      security for, and dedicated solely to, the benefits of the Holders of such
      Securities,

                  (A) in the case of Securities of a series denominated in
            currency of the United States of America,

                        (i) cash in currency of the United States of America in
                  an amount, or

                        (ii) U.S. Government Obligations which through the
                  scheduled payment of principal and interest in respect thereof
                  in accordance with their terms will provide, not later than
                  one day before the due date of any payment, an amount in cash,
                  or

                        (iii) a combination thereof, or

                  (B) in the case of Securities of a series denominated in
            currency other than that of the United States of America,

                        (i) cash in the currency in which such series of
                  Securities is denominated in an amount, or

                        (ii) Foreign Government Obligations which through the
                  scheduled payment of principal and interest in respect thereof
                  in accordance with their terms will provide, not later than
                  one day before the due date of any payment, an amount in cash,
                  or

                        (iii) a combination thereof,

      in each case sufficient, in the opinion of a nationally recognized firm of
      independent public accountants expressed in a written certification
      thereof delivered to the Trustee, to pay and discharge, and which shall be
      applied by the Trustee (or any such other qualifying trustee) to pay and
      discharge, the principal of and any premium and interest on such
      Securities on the

                                      -48-
<PAGE>

      respective Stated Maturities, in accordance with the terms of this
      Indenture and such Securities.

            (2) In the event of an election to have Section 11.02 apply to any
      Securities or any series of Securities, as the case may be, the Company
      shall have delivered to the Trustee an Opinion of Counsel stating that (A)
      the Company has received from, or there has been published by, the
      Internal Revenue Service a ruling or (B) since the date of this
      instrument, there has been a change in the applicable Federal income tax
      law, in either case (A) or (B) to the effect that, and based thereon such
      opinion shall confirm that, the Holders of such Securities will not
      recognize gain or loss for Federal income tax purposes as a result of the
      deposit, Defeasance and discharge to be effected with respect to such
      Securities and will be subject to Federal income tax on the same amount,
      in the same manner and at the same times as would be the case if such
      deposit, Defeasance and discharge were not to occur.

            (3) In the event of an election to have Section 11.03 apply to any
      Securities or any series of Securities, as the case may be, the Company
      shall have delivered to the Trustee an Opinion of Counsel to the effect
      that the Holders of such Securities will not recognize gain or loss for
      Federal income tax purposes as a result of the deposit and Covenant
      Defeasance to be effected with respect to such Securities and will be
      subject to Federal income tax on the same amount, in the same manner and
      at the same times as would be the case if such deposit and Covenant
      Defeasance were not to occur.

            (4) The Company shall have delivered to the Trustee an Officers'
      Certificate to the effect that neither such Securities nor any other
      Securities of the same series, if then listed on any securities exchange,
      will be delisted as a result of such deposit.

            (5) No event which is, or after notice or lapse of time or both
      would become, an Event of Default with respect to such Securities or any
      other Securities shall have occurred and be continuing at the time of such
      deposit or, with regard to any such event specified in Sections 6.01(e)
      and (f), at any time on or prior to the 90th day after the date of such
      deposit (it being understood that this condition shall not be deemed
      satisfied until after such 90th day).

            (6) Such Defeasance or Covenant Defeasance shall not cause the
      Trustee to have a conflicting interest within the meaning of the Trust
      Indenture Act (assuming all Securities are in default within the meaning
      of such Act).

            (7) Such Defeasance or Covenant Defeasance shall not result in a
      breach or violation of, or constitute a default under, any other agreement
      or instrument to which the Company is a party or by which it is bound.

            (8) Such Defeasance or Covenant Defeasance shall not result in the
      trust arising from such deposit constituting an investment company within
      the meaning of the Investment Company Act unless such trust shall be
      registered under such Act or exempt from registration thereunder.

                                      -49-
<PAGE>

            (9) The Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent with respect to such Defeasance or Covenant Defeasance have been
      complied with.

Section 11.05 Deposited Money, U.S. Government Obligations and Foreign
Government Obligations to be Held in Trust; Miscellaneous Provisions.

      Subject to the provisions of the last paragraph of Section 4.07, all
money, U.S. Government Obligations and Foreign Government Obligations (including
the proceeds thereof) deposited with the Trustee or other qualifying trustee
(solely for purposes of this Section and Section 13.6, the Trustee and any such
other trustee are referred to collectively as the "Trustee") pursuant to Section
11.04 in respect of any Securities shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal and any premium and interest, but money so held
in trust need not be segregated from other funds except to the extent required
by law. The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations or
Foreign Government Obligations deposited pursuant to Section 11.04 or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of Outstanding
Securities. Anything in this Article to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money, U.S. Government Obligations or Foreign Government Obligations
held by it as provided in Section 11.04 with respect to any Securities which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect the Defeasance or Covenant Defeasance, as the case may be, with respect
to such Securities.

Section 11.06 Reinstatement.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 11.02 or 11.03 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 11.05 with respect to such
Securities in accordance with this Article; provided, however, that if the
Company makes any payment of principal of or any premium or interest on any such
Security following such reinstatement of its obligations, the Company shall be
subrogated to the rights (if any) of the Holders of such Securities to receive
such payment from the money so held in trust.

      Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, in
an assignment for the benefit of creditors or any marshaling of the Company's
assets and liabilities:

      (a) holders of Senior Debt shall be entitled to receive payment in full of
all Obligations due in respect of such Senior Debt (including interest, after
the commencement of any such proceeding at the rate specified in the applicable
Senior Debt) in cash or other payment satisfactory to the holders of the Senior
Debt before holders of any Securities would be entitled to receive any payment
with respect to the Securities of any series; and

      (b) until all Senior Debt is paid in full in cash or other payment
satisfactory to the holders of the Senior Debt, any distribution to which
holders of Securities of any series would be entitled but for this Article XIII
shall be made to holders of Senior Debt, as their interests may appear.

Section 13.03 Default on Senior Debt and/or Designated Senior Debt.

      No payment or distribution may be made by the Company to the Trustee or
any holder of Securities of any series in respect of Obligations with respect to
Securities of any series and the Company may not acquire from the Trustee or any
holder of Securities any Securities until all Senior Debt has been paid in full
in cash or other payment satisfactory to the holders of the Senior Debt if:

                                      -51-
<PAGE>

      (a) a default in the payment of any principal of, premium, if any,
interest, rent or other Obligations in respect of Senior Debt occurs and is
continuing beyond any applicable grace period in the agreement, indenture or
other document governing such Senior Debt; or

      (b) a default, other than a payment default, on Designated Senior Debt
occurs and is continuing that then permits holders of such Designated Senior
Debt to accelerate its maturity and the Trustee receives a notice of the default
(a "Payment Blockage Notice") from a Person who may give it pursuant to Section
13.11 hereof.

      If the Trustee receives any Payment Blockage Notice pursuant to Section
13.03 (ii) hereof, no subsequent Payment Blockage Notice shall be effective for
purposes of such Section unless and until at least 365 days shall have elapsed
since the effectiveness of the immediately prior Payment Blockage Notice. No
nonpayment default that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

      The Company may and shall resume payments on and distributions in respect
of the Securities and may acquire them upon the earlier of:

      (a) in the case of a payment default, upon the date upon which the default
is cured or waived or ceases to exist, or

      (b) in the case of a nonpayment default referred to in Section 13.03(ii)
hereof, the earlier of the date upon which the default is cured or waived ceases
to exist or 179 days after notice is received if the maturity of such Designated
Senior Debt has not been accelerated,

if this Article XIII otherwise permits the payment, distribution or acquisition
at the time of such payment or acquisition.

Section 13.04 Acceleration of Securities.

      In the event of the acceleration of the Securities because of an Event of
Default, the Company may not make any payment or distribution to the Trustee or
any holder of Securities in respect of Obligations with respect to Securities
and may not acquire or purchase from the Trustee or any holder of Securities any
Securities until all Senior Debt has been paid in full in cash or other payment
satisfactory to the holders of Senior Debt or such acceleration is rescinded in
accordance with the terms of this Indenture.

      If payment of the Securities is accelerated because of an Event of
Default, the Company or the Trustee shall promptly notify holders of Senior Debt
or trustee(s) of such Senior Debt of the acceleration.

Section 13.05 When Distribution Must Be Paid Over.

      In the event that the Trustee, any holder of Securities or any other
Person receives any payment or distributions of assets of the Company of any
kind with respect to the Securities in contravention of any terms contained in
this Indenture, whether in cash, property or securities, including, without
limitation by way of set-off or otherwise, then such payment shall be held by
the recipient in trust for the benefit of holders of Senior Debt, and shall be
immediately paid over and delivered to the holders of Senior Debt or the
representative(s), to the extent necessary to make payment in full of all Senior
Debt remaining unpaid, after giving effect to any concurrent payment or
distribution or provision therefore, to or for the holders of Senior Debt;
provided that the foregoing shall apply to the Trustee only if the Trustee has
actual knowledge (as determined in accordance with Section 13.11) that such
payment or distribution is prohibited by this Indenture.

      With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article XIII, and no implied covenants or obligations with respect
to the holders of Senior Debt shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of holders of Securities or
the Company or any other Person money or assets to which any holders of Senior
Debt shall be entitled by virtue of this Article XIII, except if such payment is
made as a result of the willful misconduct or gross negligence of the Trustee.

Section 13.06 Notice by Company.

      The Company shall promptly notify the Trustee of any facts known to the
Company that would cause a payment of any Obligations with respect to the
Securities or the purchase of any Securities by the Company to violate this
Article XIII, but failure to give such notice shall not affect the subordination
of the Securities to the Senior Debt as provided in this Article XIII.

Section 13.07 Subrogation.

      After all Senior Debt is paid in full and until the Securities are paid in
full, holders of Securities shall be subrogated (equally and ratably with all
other indebtedness pari passu with the Securities) to the rights of holders of
Senior Debt to receive distributions applicable to Senior Debt to the extent
that distributions otherwise payable to the holders of Securities have been
applied to the payment of Senior Debt. A distribution made under this Article
XIII to holders of Senior Debt that otherwise would have been made to holders of
Securities is not, as between the Company and holders of Securities, a payment
by the Company on the Securities.

Section 13.08 Relative Rights.

      This Article XIII defines the relative rights of holders of Securities and
holders of Senior Debt. Nothing in this Indenture shall:

                                      -53-
<PAGE>

      (a) impair, as between the Company and holders of Securities, the
obligation of the Company, which is absolute and unconditional, to pay principal
of, premium, if any, and interest on the Securities in accordance with their
terms;

      (b) affect the relative rights of holders of Securities and creditors
(other than with respect to Senior Debt) of the Company, other than their rights
in relation to holders of Senior Debt; or

      (c) prevent the Trustee or any holder of Securities from exercising its
available remedies upon a Default or Event of Default, subject to the rights of
holders and owners of Senior Debt to receive distributions and payments
otherwise payable to holders of Securities.

      If the Company fails because of this Article XIII to pay principal of or
interest on a Security on the due date, the failure is still a Default or Event
of Default.

Section 13.09 Subordination May Not Be Impaired by Company.

      No right of any holder of Senior Debt to enforce the subordination of the
indebtedness evidenced by the Securities shall be impaired by any act or failure
to act by the Company or any holder of Securities or by the failure of the
Company or any such holder to comply with this Indenture.

Section 13.10 Distribution or Notice to Representative.

      Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to their
Representative.

      Upon any payment or distribution of assets of the Company referred to in
this Article XIII, the Trustee and the holders of Securities shall be entitled
to rely upon any order or decree made by any court of competent jurisdiction or
upon any certificate of such Representative or of the liquidating trustee or
agent or other Person making any distribution to the Trustee or to the holders
of Securities for the purpose of ascertaining the Persons entitled to
participate in such distribution, the holders of the Senior Debt and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article XIII.

Section 13.11 Rights of Trustee and Paying Agent.

      Notwithstanding the provisions of this Article XIII or any other provision
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment or
distribution by the Trustee (other than pursuant to Section 13.04), and the
Trustee may continue to make payments on the Securities, unless a Trust Officer
shall have received at least two Business Days prior to the date of such payment
or distribution written notice of facts that would cause such payment or
distribution with respect to the Securities to violate this Article XIII. Only
the Company or a Representative may give the notice.

                                      -54-
<PAGE>

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

      The Trustee in its individual or any other capacity may hold Senior Debt
with the same rights it would have if it were not Trustee. Any Agent may do the
same with like rights.

Section 13.12 Authorization to Effect Subordination.

      Each holder of a Security by the holder's acceptance thereof authorizes
and directs the Trustee on the holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article XIII, and appoints the Trustee to act as the holder's attorney-in-fact
for any and all such purposes. If the Trustee does not file a proper proof of
claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file
such claim, the holders of any Senior Debt or their Representatives are hereby
authorized to file an appropriate claim for and on behalf of the holders of the
Securities.

Section 13.13 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 XIII 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 XIII in addition to or in place of the Trustee; provided,
however, that the second and third paragraphs of Section 13.11 shall not apply
to the Company or any Subsidiary of the Company if it or such Subsidiary acts as
Paying Agent.

Section 13.14 Senior Debt Entitled to Rely.

      The holders of Senior Debt shall have the right to rely upon this Article
XIII, and no amendment or modification of the provisions contained herein shall
diminish the rights of such holders unless such holders shall have agreed in
writing thereto.

Section 13.15 Permitted Payments.

      Notwithstanding anything to the contrary in this Article XIII, the holders
of Securities may receive and retain at any time on or prior to the Maturity
Date (i) securities that are subordinated to at least the same extent as the
Securities to (a) Senior Debt and (b) any securities issued in exchange for
Senior Debt and (ii) payments and other distributions made from any trust
created pursuant to Section 14.01 hereof.

Section 13.16 Certain Conversions Deemed Payment.

      For the purposes of this Article XIII only, (1) the issuance and delivery
of junior securities upon conversion of Securities in accordance with Article
XII shall not be deemed to constitute a

                                      -55-
<PAGE>

payment or distribution on account of the principal of (or premium, if any) or
interest on Securities or on account of the purchase or other acquisition of
Securities, and (2) the payment, issuance or delivery of cash, property or
securities (other than junior securities) upon conversion of a Security shall be
deemed to constitute payment on account of the principal of such Security. For
the purposes of this Section 13.16, the term "junior securities" means (a)
shares of any stock of any class of the Company, or (b) securities of the
Company which are subordinated in right of payment to all Senior Debt which may
be outstanding at the time of issuance or delivery of such securities to
substantially the same extent as, or to a greater extent than, the Securities
are so subordinated as provided in this Article.

                                   ARTICLE 14
                     SATISFACTION AND DISCHARGE OF INDENTURE

Section 14.01 Discharge of Indenture.

      When (a) the Company delivers to the Trustee for cancellation all
Securities theretofore authenticated (other than any other Securities which have
been destroyed, lost or stolen and in lieu of or in substitution for which other
Securities have been authenticated and delivered) and not theretofore canceled,
or (b) all the Securities not theretofore canceled or delivered to the Trustee
for cancellation have become due and payable, or are by their terms will become
due and payable at their Stated Maturity 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, amounts sufficient to pay at Stated Maturity or upon the Redemption
Date of all of the Securities (other than any Securities which have been
mutilated, destroyed, lost or stolen and in lieu of or in substitution for which
other Securities have been authenticated and delivered) not theretofore canceled
or delivered to the Trustee for cancellation, including principal and premium,
if any, and interest due or to become due to such date of Stated Maturity or
Redemption Date, 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 and premium, if any, and interest on, the
Securities, (iii) the obligations under Sections 2.04 and 14.05 hereof and (iv)
the rights, obligations and immunities of the Trustee hereunder), and the
Trustee, on demand of the Company accompanied by an Officers' Certificate and an
Opinion of Counsel as required by Section 9.04 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 compensate the Trustee for any services thereafter reasonably
and properly rendered by the Trustee in connection with this Indenture or the
Securities.

Section 14.02 Deposited Monies to be Held in Trust by Trustee.

      Subject to Section 14.04, all monies deposited with the Trustee pursuant
to Section 14.01 shall be held in trust and applied by it to the payment,
notwithstanding the provisions of Article XI, 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 and interest, and premium, if
any.

Section 14.03 Paying Agent to Repay Monies Held.

      Upon the satisfaction and discharge of this Indenture, all monies then
held by any Paying Agent (other than the Trustee) shall, upon the Company's
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 14.04 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, or
interest on 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, or interest on such Securities, as the case may be, have become due and
payable, shall be repaid to the Company by the Trustee on demand; provided,
however, that the Company, or the Trustee at the request of the Company, shall
have first caused notice of such payment to the Company to be mailed to each
holder of a Security 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 14.05 Reinstatement.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 14.02 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 14.01 until such time as the Trustee or the Paying Agent is permitted to
apply all such money in accordance with Section 14.02; provided, however, that
if the Company makes any payment of interest 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.
