          (ii) Restricted Securities Legend for the Common Stock Issued Upon
     Conversion of the Securities.

     Each stock certificate representing Common Stock issued upon conversion of
Securities bearing a Restricted Securities Legend will, subject to the
availability of a Shelf Registration Statement and registration thereunder as
set forth in the Registration Rights Agreement, bear the following legend:

"THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF
1933, AS AMENDED (THE "SECURITIES ACT"), AND ACCORDINGLY, MAY NOT BE OFFERED OR
SOLD EXCEPT

                                       15

AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER
AGREES (1) THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED
HEREBY, EXCEPT (A) TO THE ISSUER; (B) UNDER A REGISTRATION STATEMENT THAT HAS
BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT; (C) TO A PERSON THE SELLER
REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A

CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED TO
CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

          (iii) Removal of the Restricted Securities Legends.

     The Restricted Securities Legend may be removed from any Security or any
Common Stock certificate representing shares of the Common Stock issued upon
conversion of any Security if there is delivered to the Company such
satisfactory evidence, which may include an opinion of independent counsel, as
may be reasonably required by the Company, that neither such legend nor the
restrictions on transfer set forth therein are required to ensure that transfers
of such Security or shares of the Common Stock issued upon conversion of
Securities, as the case may be, will not violate the registration requirements
of the Securities Act or the qualification requirements under any state
securities laws. Upon provision of such satisfactory evidence to the Company, at
the written direction of the Company, (i) in the case of a Security, the Trustee
shall authenticate and deliver in exchange for such Security another Security or
Securities having an equal aggregate principal amount that does not bear such
legend or (ii) in the case of a Common Stock certificate representing shares of
the Common Stock, the transfer agent for the Common Stock shall authenticate and
deliver in exchange for the Common Stock certificate or certificates
representing such shares of Common Stock bearing such legend, one or more new
Common Stock certificates representing a like aggregate number of shares of
Common Stock that do not bear such legend. If the Restricted Securities Legend
has been removed from a Security or Common Stock certificates representing
shares of the Common Stock issued upon conversion of any Security as provided
above, no other Security issued in exchange for all or any part of such
Security, or no other

                                       16

<PAGE>

Common Stock certificates issued in exchange for such Common Stock shall bear
such legend, unless the Company has reasonable cause to believe that such other
Security is a "restricted security" (or such shares of Common Stock are
"restricted securities") within the meaning of Rule 144 and instructs the
Trustee in writing to cause a Restricted Securities Legend to appear thereon.

     Any Security (or Security issued in exchange or substitution therefor) as
to which the conditions for removal of the Restricted Securities Legend set
forth in Section 2.03(a)(i) as set forth therein have been satisfied may, upon
surrender of such Security for exchange to the Registrar in accordance with the
provisions of Section 2.08, be exchanged for a new Security or Securities, of
like tenor and aggregate principal amount, which shall not bear the Restricted
Securities Legend required by Section 2.03(a)(i).

     Any Common Stock certificate representing shares of Common Stock issued
upon conversion of any Security as to which the conditions for removal of the
Restricted Securities Legend set forth in Section 2.03(a)(ii) have been
satisfied may, upon surrender of the Common Stock certificates representing such
shares of Common Stock for exchange in accordance with the procedures of the
transfer agent for the Common Stock, be exchanged for a new Common Stock
certificate or certificates representing a like aggregate number of shares of
Common Stock, which shall not bear the Restricted Securities Legend.

          (iv) Global Security Legend.

     Each Global Security shall also bear the following legend (the "GLOBAL
SECURITY LEGEND") on the face thereof:

"UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), NEW YORK, NEW YORK, TO
THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND
ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER
NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS
MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER
HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT
NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S
NOMINEE AND

                                       17

<PAGE>

TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE
IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO IN
THE TERMS OF SECURITIES ATTACHED HERETO."

          (v) Legend for Definitive Securities.

     Definitive Securities, in addition to the legend set forth in Section
2.03(a)(i), will also bear a legend substantially in the following form:

"THIS SECURITY WILL NOT BE ACCEPTED IN EXCHANGE FOR A BENEFICIAL INTEREST IN A
GLOBAL SECURITY UNLESS THE HOLDER OF THIS SECURITY, SUBSEQUENT TO SUCH EXCHANGE,
WILL HOLD NO SECURITIES."

     Section 2.04. Execution and Authentication. One Officer 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 the Trustee
authenticates the Security, the Security shall be valid nevertheless.

     A Security shall not be valid until an authorized signatory of the Trustee
manually authenticates the Security. The signature of the Trustee on a Security
shall be conclusive evidence that such Security has been duly and validly
authenticated and issued under this Indenture. A Security shall be dated the
date of its authentication.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities executed by the Company in an
unlimited aggregate principal amount to the Trustee for authentication, together
with a written order of the Company signed by two Officers or by an Officer and
either an Assistant Treasurer or an Assistant Secretary of the Company (the
"COMPANY ORDER") for the authentication and delivery of such Securities, and the
Trustee in accordance with such Company Order shall authenticate and deliver
such Securities as in this Indenture provided and not otherwise. All Securities
issued on the Issue Date shall be identical in all respects with any such
Securities authenticated and delivered thereafter, other than issue dates, the
date from which interest accrues, appropriate CUSIP numbers or other identifying
notations and any changes relating thereto. Notwithstanding anything to the
contrary contained in this Indenture, subject to Section 2.12, all Securities
issued under this Indenture shall vote and consent together on all matters as
one class and no series of Securities will have the right to vote or consent as
a separate class on any matter.

     The Trustee may appoint an agent (the "AUTHENTICATING AGENT") reasonably
acceptable to the Company to authenticate the Securities. Initially, the

                                       18

<PAGE>

Trustee will act as the Authenticating Agent. Any such instrument shall be
evidenced by an instrument signed by a Trust Officer of the Trustee, a copy of
which shall be furnished to the Company. Unless limited by the terms of such
appointment, any such Authenticating Agent may authenticate Securities whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by the Authenticating Agent. An Authenticating
Agent has the same rights as any Registrar, Paying Agent or agent for service of
notices and demands.

     In case the Company or any Subsidiary Guarantor, pursuant to Article 4 or
Section 10.02, shall be consolidated or merged with or into any other Person or
shall convey, transfer, lease or otherwise dispose of its properties and assets
substantially as an entirety to any Person, and the successor Person resulting
from such consolidation, or surviving such merger, or into which the Company or
any Subsidiary Guarantor shall have been merged, or the Person which shall have
received a conveyance, transfer, lease or other disposition as aforesaid, shall
have executed an indenture supplemental hereto with the Trustee pursuant to
Article 4, any of the Securities authenticated or delivered prior to such
consolidation, merger, conveyance, transfer, lease or other disposition may,
from time to time, at the request of the successor Person, be exchanged for
other Securities executed in the name of the successor Person with such changes
in phraseology and form as may be appropriate, but otherwise in substance of
like tenor as the Securities surrendered for such exchange and of like principal
amount; and the Trustee, upon Company Order of the successor Person, shall
authenticate and deliver Securities as specified in such order for the purpose
of such exchange. If Securities shall at any time be authenticated and delivered
in any new name of a successor Person pursuant to this Section 2.04 in exchange
or substitution for or upon registration of transfer of any Securities, such
successor Person, at the option of the Holders but without expense to them,
shall provide for the exchange of all Securities at the time outstanding for
Securities authenticated and delivered in such new name.

     Section 2.05. Registrar and Paying Agent. The Company shall maintain an
office or agency where Securities may be presented for registration of transfer
or for exchange (the "REGISTRAR") and an office or agency where Securities may
be presented for payment (the "PAYING AGENT"). The Company shall cause each of
the Registrar and the Paying Agent to maintain an office or agency in the
Borough of Manhattan, The City of New York. The Registrar shall keep a register
of the Securities and of their transfer and exchange (the "SECURITIES
REGISTER"). The Company may have one or more co-registrars and one or more
additional paying agents. The term "PAYING AGENT" includes any additional paying
agent and the term "REGISTRAR" includes any co-registrar.

     The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall

                                       19

<PAGE>

incorporate the terms of the TIA. The agreement shall implement the provisions
of this Indenture that relate to such agent. The Company shall notify the
Trustee of the name and address of each such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically organized, wholly owned Subsidiaries may act
as Paying Agent, Registrar, co-registrar or transfer agent.

     The Company initially appoints the Trustee as Registrar and Paying Agent
for the Securities. The Company may remove any Registrar or Paying Agent upon
written notice to such Registrar or Paying Agent and to the Trustee; provided,
however, that no such removal shall become effective until (i) acceptance of any
appointment by a successor as evidenced by an appropriate agreement entered into
by the Company and such successor Registrar or successor Paying Agent, as the
case may be, and delivered to the Trustee or (ii) notification to the Trustee
that the Trustee shall serve as Registrar or Paying Agent until the appointment
of a successor in accordance with clause (i) above. The Registrar or Paying
Agent may resign at any time upon written notice to the Company and the Trustee.

     Section 2.06. Paying Agent to Hold Money in Trust. By no later than 11:00
a.m., New York City time, on the date on which any principal of or interest and
Contingent Interest and Liquidated Damages, if any, on any Security is due and
payable, the Company shall deposit with the Paying Agent a sum sufficient in
immediately available funds to pay such principal or interest (including any
Contingent Interest and Liquidated Damages), when due. The Company shall require
each Paying Agent (other than the Trustee) to agree in writing that such Paying
Agent shall hold in trust for the benefit of Securityholders or the Trustee all
money held by such Paying Agent for the payment of principal of or interest
(including any Contingent Interest and Liquidated Damages), on the Securities
and shall notify the Trustee in writing of any default by the Company or any
Subsidiary Guarantor in making any such payment. If the Company or a Subsidiary
acts as Paying Agent, it shall segregate the money held by it as Paying Agent
and hold it as a separate trust fund. The Company at any time may require a
Paying Agent (other than the Trustee) to pay all money held by it to the Trustee
and to account for any funds disbursed by such Paying Agent. Upon complying with
this Section 2.06, the Paying Agent (if other than the Company or a Subsidiary)
shall have no further liability for the money delivered to the Trustee. Upon any
bankruptcy, reorganization or similar proceeding with respect to the Company,
the Trustee shall serve as Paying Agent for the Securities.

     Section 2.07. Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Securityholders and shall otherwise comply with
TIA Section 312(a). If the Trustee is not the Registrar, or to the extent
otherwise required

                                       20

<PAGE>

under the TIA, the Company, on its own behalf and on behalf of each of the
Subsidiary Guarantors, shall furnish or cause the Registrar to furnish to the
Trustee, in writing at least five 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 Securityholders and the Company shall otherwise comply with TIA
Section 312(a).

     Section 2.08. General Provisions Relating to Transfer and Exchange. The
Securities are issuable only in registered form. A Holder may transfer a
Security only by written application to the Registrar stating the name of the
proposed transferee and otherwise complying with the terms of this Indenture. No
such transfer shall be effected until, and such transferee shall succeed to the
rights of a Holder only upon, final acceptance and registration of the transfer
by the Registrar in the Securities Register. Furthermore, any Holder of a Global
Security shall, by acceptance of such Global Security, agree that transfers of
beneficial interests in such Global Security may be effected only through a
book-entry system maintained by the Holder of such Global Security (or its
agent) and that ownership of a beneficial interest in the Global Security shall
be required to be reflected in a book-entry.

     When Securities are presented to the Registrar with a request to register
the transfer or to exchange them for an equal aggregate principal amount of
Securities of other authorized denominations, the Registrar shall register the
transfer or make the exchange as requested if its requirements for such
transactions are met (including that such Securities are duly endorsed or
accompanied by a written instrument of transfer duly executed by the Holder
thereof or by an attorney who is authorized in writing to act on behalf of the
Holder). Subject to Section 2.04, to permit registrations of transfers and
exchanges, the Company shall execute and the Trustee shall authenticate
Securities at the Registrar's request. No service charge shall be made for any
registration of transfer or exchange or redemption of the Securities, but the
Company may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than any such
transfer taxes or other similar governmental charge payable upon exchanges in
connection with which a Security is issued to a Person other than the Holder
submitting the Security for exchange).

     Neither the Company nor the Registrar shall be required to exchange or
register a transfer of any Securities:

     (a) for a period of 15 days prior to the mailing of a notice of redemption
of Securities selected for redemption under Article 5;

                                       21
<PAGE>

     (b) so selected for redemption or, if a portion of any Security is selected
for redemption, the portion thereof selected for redemption; or

     (c) surrendered for conversion or, if a portion of any Security is
surrendered for conversion, the portion thereof surrendered for conversion.

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

     Section 2.09. Book-Entry Provisions for the Global Securities. (a) The
Global Securities initially shall:

          (i) be registered in the name of DTC (or a nominee thereof);

          (ii) be delivered to the Trustee as custodian for DTC;

          (iii) bear the Restricted Securities Legend set forth in Section
     2.03(a)(i); and

          (iv) bear the Global Security Legend set forth in Section 2.03(a)(iv).

     Members of, or participants in, DTC ("AGENT MEMBERS") shall have no rights
under this Indenture with respect to any Global Security held on their behalf by
DTC or the Trustee as its custodian, or under such Global Security, and DTC may
be treated by the Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner of such Global Security for all purposes
whatsoever. Notwithstanding the foregoing, nothing contained herein shall
prevent the Company, the Trustee or any agent of the Company or Trustee from
giving effect to any written certification, proxy or other authorization
furnished by DTC or impair, as between DTC and the Agent Members, the operation
of customary practices governing the exercise of the rights of a Holder of any
Security.

     (b) The Holder of a Global Security may grant proxies and otherwise
authorize any Person, including Agent Members and Persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Securities.

                                       22

<PAGE>

     (c) A Global Security may not be transferred, in whole or in part, to any
Person other than DTC (or a nominee thereof), and no such transfer to any such
other Person may be registered. Beneficial interests in a Global Security may be
transferred in accordance with the rules and procedures of DTC and the
provisions of Section 2.10.

     (d) If at any time:

          (i) DTC notifies the Company in writing that it is unwilling or unable
     to continue to act as depositary for the Global Securities and a successor
     depositary for the Global Securities is not appointed by the Company within
     90 days of such notice;

          (ii) DTC ceases to be registered as a "clearing agency" under the
     Exchange Act and a successor depositary for the Global Securities is not
     appointed by the Company within 90 days of such cessation;

          (iii) the Company, at its option, notifies the Trustee in writing that
     it elects to cause the issuance of the Definitive Securities under this
     Indenture in exchange for all or any part of the Securities represented by
     a Global Security or Global Securities, subject to the procedures of DTC;
     or

          (iv) an Event of Default has occurred and is continuing and the
     Registrar has received a request from DTC for the issuance of Definitive
     Securities in exchange for such Global Security or Global Securities;

DTC shall surrender such Global Security or Global Securities to the Trustee for
cancellation and the Company shall execute, and the Trustee, upon receipt of an
Officers' Certificate and Company Order for the authentication and delivery of
Securities, shall authenticate and deliver in exchange for such Global Security
or Global Securities, Definitive Securities in an aggregate principal amount
equal to the aggregate principal amount of such Global Security or Global
Securities. Such Definitive Securities shall be registered in such names as DTC
shall identify in writing as the beneficial owners of the Securities represented
by such Global Security or Global Securities (or any nominee thereof).

     (e) Notwithstanding the foregoing, in connection with any transfer of
beneficial interests in a Global Security to the beneficial owners thereof
pursuant to Section 2.09(d), the Registrar shall reflect on its books and
records the date and a decrease in the principal amount of such Global Security
in an amount equal to the principal amount of the beneficial interests in such
Global Security to be transferred.

                                       23

<PAGE>

     Section 2.10. Special Transfer Provisions. Unless a Security is no longer
a Restricted Security, the following provisions shall apply to any sale, pledge
or other transfer of such Securities:

     (a) Transfer of Securities to a QIB.

     The following provisions shall apply with respect to the registration of
any proposed transfer of Securities to a QIB:

          (i) If the Securities to be transferred consist of a beneficial
     interest in the Global Securities, the transfer of such interest may be
     effected only through the book-entry systems maintained by DTC.

          (ii) If the Securities to be transferred consist of Definitive
     Securities, the Registrar shall register the transfer if such transfer is
     being made by a proposed transferor who has checked the box provided for on
     the form of Security stating (or has otherwise advised the Company and the
     Registrar in writing) that the sale has been made in compliance with the
     provisions of Rule 144A to a transferee who has signed a certification
     stating or has otherwise advised the Company and the Registrar in writing
     that:

               (A) it is purchasing the Securities for its own account or an
          account with respect to which it exercises sole investment discretion;

               (B) it and any such account is a QIB within the meaning of Rule
          144A;

               (C) it is aware that the sale to it is being made in reliance on
          Rule 144A;

               (D) it acknowledges that it has received such information
          regarding the Company as it has requested pursuant to Rule 144A or has
          determined not to request such information; and

               (E) it is aware that the transferor is relying upon its foregoing
          representations in order to claim the exemption from registration
          provided by Rule 144A.

     (b) General.

     By its acceptance of any Security bearing the Restricted Securities Legend,
each Holder of such a Security acknowledges the restrictions on transfer of such
Security set forth in this Indenture and agrees that it will transfer such
Security only as provided in this Indenture. The Registrar shall not register a

                                       24

<PAGE>

transfer of any Security unless such transfer complies with the restrictions on
transfer of such Security set forth in this Indenture. The Registrar shall be
entitled to receive and rely on written instructions from the Company verifying
that such transfer complies with such restrictions on transfer. In connection
with any transfer of Securities, each Holder agrees by its acceptance of the
Securities to furnish the Registrar or the Company such certifications, legal
opinions or other information as either of them may reasonably require to
confirm that such transfer is being made pursuant to an exemption from, or a
transaction not subject to, the registration requirements of the Securities Act;
provided that the Registrar shall not be required to determine (but may rely on
a determination made by the Company with respect to) the sufficiency of any such
certifications, legal opinions or other information.

     The Registrar shall retain copies of all certifications, letters, notices
and other written communications received pursuant to Section 2.09 hereof or
this Section 2.10. The Company shall have the right to inspect and make copies
of all such letters, notices or other written communications at any reasonable
time upon the giving of reasonable written notice to the Registrar.

     Section 2.11. Mutilated, Destroyed, Lost or Stolen Securities. If a
mutilated Security is surrendered to the Registrar or if the Holder of a
Security claims that the Security has been lost, destroyed or wrongfully taken,
the Company shall issue and the Trustee shall authenticate a replacement
Security if the requirements of Section 8-405 of the UCC are met, such that the
Securityholder (a) satisfies the Company or the Trustee within a reasonable time
after such Securityholder has notice of such loss, destruction or wrongful
taking and the Registrar has not registered a transfer prior to receiving such
notification, (b) makes such request to the Company or Trustee prior to the
Security being acquired by a protected purchaser as defined in Section 8-303 of
the UCC and (c) satisfies any other reasonable requirements of the Trustee. Such
Holder shall furnish an indemnity bond sufficient in the judgment of the Company
and the Trustee to protect the Company, the Trustee, the Paying Agent and the
Registrar from any loss which any of them may suffer if a Security is replaced,
and, in the absence of notice to the Company, any Subsidiary Guarantor or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
make available for delivery, in exchange for any such mutilated Security or in
lieu of any such destroyed, lost or stolen Security, a new Security of like
tenor and principal amount, bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
due and payable, the Company in its discretion may, instead of issuing a new
Security, pay such Security.

                                       25

<PAGE>

     Upon the issuance of any new Security under this Section 2.11, the Company
may require the payment by the Holder of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
therewith.

     Every new Security issued pursuant to this Section 2.11 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, any Subsidiary Guarantor (if
applicable) and any other obligor upon the Securities, whether or not the
mutilated, destroyed, lost or stolen Security shall be at any time enforceable
by anyone, and shall be entitled to all benefits of this Indenture equally and
ratably with any and all other Securities duly issued hereunder.

     The provisions of this Section 2.11 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

     Section 2.12. Outstanding Securities. Securities outstanding at any time
are all Securities authenticated by the Trustee except for those cancelled by
it, those delivered to it for cancellation and those described in this Section
2.12 as not outstanding. A Security does not cease to be outstanding in the
event the Company or a Subsidiary of the Company holds the Security; provided,
however, that (i) for purposes of determining which Securities are outstanding
for consent or voting purposes hereunder, the provisions of Section 14.06 shall
apply and (ii) in determining whether the Trustee shall be protected in making a
determination whether the Holders of the requisite principal amount of
outstanding Securities are present at a meeting of Holders of Securities for
quorum purposes or have consented to or voted in favor of any request, demand,
authorization, direction, notice, consent, waiver, amendment or modification
hereunder, or relying upon any such quorum, consent or vote, only Securities
which a Trust Officer of the Trustee actually knows to be held by the Company or
an Affiliate of the Company shall not be considered outstanding.

     If a Security is replaced or paid pursuant to Section 2.11, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

     If the Paying Agent segregates and holds in trust, in accordance with this
Indenture, on a Redemption Date or at Stated Maturity, money sufficient to pay
all principal and interest payable on that date with respect to the Securities
(or portions thereof) to be redeemed or maturing, as the case may be, and the
Paying Agent is not prohibited from paying such money to the Securityholders on
that date pursuant to the terms of this Indenture, then on and after that date,
such

                                       26

<PAGE>

Securities (or portions thereof) cease to be outstanding and interest on them
ceases to accrue.

     Section 2.13. Temporary Securities. In the event that Definitive Securities
are to be issued under the terms of this Indenture, until such Definitive
Securities are ready for delivery, the Company may prepare and upon receipt of a
Company Order the Trustee shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form of Definitive Securities but may
have variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and upon receipt of a
Company Order the Trustee shall authenticate Definitive Securities. After the
preparation of Definitive Securities, the temporary Securities shall be
exchangeable for Definitive Securities upon surrender of the temporary
Securities at any office or agency maintained by the Company for that purpose
and such exchange shall be without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities, the Company shall execute,
and the Trustee shall authenticate and make available for delivery in exchange
therefor, one or more Definitive Securities representing an equal principal
amount of Securities. Until so exchanged, the Holder of temporary Securities
shall in all respects be entitled to the same benefits under this Indenture as a
Holder of Definitive Securities.

     Section 2.14. Cancellation. The Company at any time may deliver Securities
to the Trustee for cancellation. The Registrar and the Paying Agent shall
forward to the Trustee any Securities surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment or
cancellation and dispose of such Securities in accordance with its internal
policies and customary procedures including, if requested by the Company,
delivery of a certificate (a "CERTIFICATE OF DESTRUCTION") describing such
Securities disposed (subject to the record retention requirements of the
Exchange Act) or deliver canceled Securities to the Company pursuant to written
direction by an Officer. The Company may not issue new Securities to replace
Securities it has paid for or delivered to the Trustee for cancellation for any
reason other than in connection with a transfer or exchange.

     At such time as all beneficial interests in a Global Security have either
been exchanged for Definitive Securities, transferred, redeemed, repurchased or
canceled, such Global Security shall be returned by DTC to the Trustee for
cancellation or retained and canceled by the Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Security is exchanged for
Definitive Securities, transferred in exchange for an interest in another Global
Security, redeemed, repurchased or canceled, the principal amount of Securities
represented by such Global Security shall be reduced and an adjustment shall be
made on the books and records of the Trustee (if it is then the Securities

                                       27

<PAGE>

Custodian for such Global Security) with respect to such Global Security, by the
Trustee or the Securities Custodian, to reflect such reduction.

     Section 2.15. Payment of Interest; Defaulted Interest. Interest (including
any Contingent Interest and Liquidated Damages) on any Security which is
payable, and is punctually paid or duly provided for, on any interest payment
date shall be paid to the Person in whose name such Security (or one or more
predecessor Securities) is registered at the close of business on the Regular
Record Date for such payment at the office or agency of the Company maintained
for such purpose pursuant to Section 2.05.

     Any interest on any Security which is payable, but is not paid when the
same becomes due and payable and such nonpayment continues for a period of 30
days, shall forthwith cease to be payable to the Holder on the Regular Record
Date, and such defaulted interest and (to the extent lawful) interest on such
defaulted interest at the rate borne by the Securities (such defaulted interest
and interest thereon herein collectively called "DEFAULTED INTEREST") shall be
paid by the Company, at its election in each case, as provided in clause (a) or
(b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities (or their respective predecessor
Securities) are registered at the close of business on a Special Record Date (as
defined below) for the payment of such Defaulted Interest, which shall be fixed
in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security and the date
(not less than 45 days after such notice) of the proposed payment (the "SPECIAL
INTEREST PAYMENT DATE"), and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for such deposit prior to the date of the proposed payment, such
money when deposited to be held in trust for the benefit of the Persons entitled
to such Defaulted Interest as in this clause provided. Thereupon the Trustee
shall fix a record date (the "SPECIAL RECORD DATE") for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10
days prior to the Special Interest Payment Date and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment. The Trustee
shall promptly notify the Company of such Special Record Date, and in the name
and at the expense of the Company, shall cause notice of the proposed payment of
such Defaulted Interest and the Special Record Date and Special Interest Payment
Date therefor to be given in the manner provided for in Section 14.02, not less
than 10 days prior to such Special Record Date. Notice of the proposed payment
of such Defaulted Interest and the Special Record Date and Special Interest
Payment Date therefor having been so given, such Defaulted Interest shall be
paid on the Special Interest Payment Date to the Persons in whose names the
Securities (or their respective predecessor Securities) are registered at the
close of business on such

                                       28

<PAGE>

Special Record Date and shall no longer be payable pursuant to the following
clause (b).

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

     Subject to the foregoing provisions of this Section 2.15, each Security
delivered under this Indenture upon registration of, transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest
(including any Contingent Interest and Liquidated Damages) accrued and unpaid,
and to accrue, which were carried by such other Security.

     Section 2.16. Computation of Interest. Interest (including any Contingent
Interest and Liquidated Damages) on the Securities shall be computed on the
basis of a 360-day year of twelve 30-day months.

     Section 2.17. Cusip and ISIN Numbers. The Company in issuing the Securities
may use "CUSIP" and "ISIN" numbers (if then generally in use) and, if so, the
Trustee shall use "CUSIP" and "ISIN" numbers in notices of redemption as a
convenience to Holders; provided, however, that any such notice may state that
no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such CUSIP or ISIN numbers. The Company shall promptly notify the
Trustee in writing of any change in the CUSIP and ISIN numbers.

     Section 2.18. Contingent Debt Tax Treatment. (a) The Company and each
Holder, by acquiring a beneficial interest in a Security, agree (i) to treat the
Security as indebtedness for U.S. federal income tax purposes that is subject to
the Treasury regulations governing contingent payment debt instruments (the
"CONTINGENT DEBT REGULATIONS"), (ii) that each Holder shall be bound by the
Company's application of the contingent debt regulations to the Security,
including the Company's determination of the "comparable yield" and "projected
payment schedule" within the meaning of the contingent debt regulations, (iii)
to treat the cash and the fair market value of any Common Stock received upon
the conversion of the Security as a contingent payment for purposes of the
contingent debt regulations, (iv) to accrue interest with respect to the
outstanding Security as Tax Original Issue Discount according to the
"noncontingent bond method" set forth in the contingent debt regulations, using
the comparable yield of 7.13% compounded semi-annually and (v) that the Company
and each Holder will not

                                       29

<PAGE>

take any position on any U.S. federal income tax return that is inconsistent
with (i), (ii), (iii) or (iv) unless required by applicable law. A Holder may
obtain the issue price, amount of Tax Original Issue Discount, issue date, yield
to maturity, comparable yield and projected payment schedule for the Security,
as determined by the Company pursuant to the contingent debt regulations, by
submitting a written request to the Company at the following address: King
Pharmaceuticals, Inc., 501 Fifth Street, Bristol, Tennessee 37620, Attention:
Treasury Department.

     (b) Each Security shall bear a legend relating to U.S. federal income tax
matters in the form set forth in Exhibit A.

     Section 2.19. Calculation Of Tax Original Issue Discount. The Company shall
file with the Trustee promptly at the end of each calendar year (i) a written
notice specifying the amount of Tax Original Issue Discount (including daily
rates and accrual periods) accrued on outstanding Securities as of the end of
such year and (ii) such other specific information relating to such Tax Original
Issue Discount as may then be required under the Code or the Treasury
regulations promulgated thereunder.

                                    ARTICLE 3
                                    COVENANTS

     Section 3.01. Payment of Securities. The Company shall promptly pay the
principal of and interest (including any Contingent Interest and Liquidated
Damages) on the Securities on the dates and in the manner provided in the
Securities and in this Indenture. Principal and interest (including any
Contingent Interest and Liquidated Damages) shall be considered paid on the date
due if on such date the Trustee or the Paying Agent holds, in accordance with
this Indenture, immediately available funds sufficient to pay all principal and
interest (including any Contingent Interest and Liquidated Damages) then due and
the Trustee or the Paying Agent, as the case may be, is not prohibited from
paying such money to the Securityholders on that date pursuant to the terms of
this Indenture.

     The Company shall pay interest on overdue principal at the rate specified
therefor in the Securities, and it shall pay interest on overdue installments of
interest at the same rate to the extent lawful.

     Notwithstanding anything to the contrary contained in this Indenture, the
Company may, to the extent it is required to do so by law, deduct or withhold
income or other similar taxes imposed by the United States of America from
principal or interest (including any Contingent Interest and Liquidated Damages)
payments hereunder.

                                       30

<PAGE>

     Section 3.02. Financial Statements. Within a period of two years after the
Issue Date, in the event and for so long as the Company is not subject to
Section 13 or 15(d) of the Exchange Act, the Company shall file with the Trustee
and cause to be mailed to each Holder at such Holder's registered address, upon
the request of any Holder or Beneficial Owner of the Securities or the Common
Stock issued upon conversion thereof, and make available to such Holder or
beneficial holder of such Securities or Common Stock in connection with any sale
thereof and any prospective purchaser of Securities or Common Stock designated
by such Holder or beneficial holder, the information required pursuant to Rule
144A(d)(4) under the Securities Act and the Company will take such further
action as any Holder or beneficial holder of such Securities or Common Stock may
reasonably request, all to the extent required from time to time to enable such
Holder or beneficial holder to sell its Securities or Common Stock without
registration under the Securities Act within the limitation of the exemption
provided by Rule 144A, as such Rule may be amended from time to time.

     Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     Section 3.03. Maintenance of Office or Agency. The Company will maintain in
the Borough of Manhattan, The City of New York, an office or agency where the
Securities may be presented or surrendered for payment, where, if applicable,
the Securities may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Company in respect of the Securities
and this Indenture may be served. The office of the Trustee (the "AGENT")
currently located in The City of New York shall be such office or agency of the
Company, unless the Company shall designate and maintain some other office or
agency for one or more of such purposes. The Company will give prompt written
notice to the Trustee of any change in the location of any 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
Agent of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other offices
or agencies (in or outside of The City of New York) where the Securities may be
presented or surrendered for any or all such purposes and may from time to time
rescind any such designation; 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 City of New York for such purposes. The

                                       31

<PAGE>

Company will give prompt written notice to the Trustee of any such designation
or rescission and any change in the location of any such other office or agency.

     Section 3.04. Corporate Existence. Except as otherwise provided in Article
4 and Section 10.02(b), the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence
and the corporate, partnership, limited liability company or other existence of
each Subsidiary Guarantor and the rights (charter and statutory), licenses and
franchises of the Company and each Subsidiary Guarantor; provided, however, that
the Company shall not be required to preserve any such right, license or
franchise or the corporate, partnership, limited liability company or other
existence of any Subsidiary Guarantor if the Board of Directors of the Company
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and each of its Subsidiaries, taken as a
whole, and that the loss thereof is not, and will not be, disadvantageous in any
material respect to the Holders.

     Section 3.05. Compliance Certificate. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate, one of the signers of which shall be the principal
executive officer, principal financial officer or principal accounting officer
of the Company, stating that in the course of the performance by the signers of
their duties as Officers of the Company they would normally have knowledge of
any Default or Event of Default and whether or not the signers know of any
Default or Event of Default that occurred during such period. If they do, the
certificate shall describe the Default or Event of Default, its status and the
action the Company is taking or proposes to take with respect thereto. The
Company also shall comply with TIA Section 314(a)(4).

     Section 3.06. Further Instruments and Acts. Upon request of the Trustee,
the Company will execute and deliver such further instruments and do such
further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

     Section 3.07. Statement by Officers as to Default. The Company shall
deliver to the Trustee, as soon as possible and in any event within 30 days
after the Company becomes aware of the occurrence of any Event of Default or an
event which, with notice or the lapse of time or both, would constitute an Event
of Default, an Officers' Certificate setting forth the details of such Event of
Default or Default, its status and the action which the Company proposes to take
with respect thereto.

     Section 3.08. Contingent Interest and Liquidated Damages. If Liquidated
Damages or Contingent Interest is payable by the Company pursuant to the
Registration Rights Agreement, the Company shall deliver to the Trustee an

                                       32

<PAGE>

Officers' Certificate to that effect stating (i) the amount of such Liquidated
Damages or Contingent Interest that is payable and (ii) the date on which such
Liquidated Damages or Contingent Interest is payable. Unless and until a Trust
Officer of the Trustee receives such a certificate, the Trustee may assume
without inquiry that no Liquidated Damages or Contingent Interest is payable. If
the Company has paid Liquidated Damages or Contingent Interest directly to the
persons entitled to it, the Company shall deliver to the Trustee an Officers'
Certificate setting forth the particulars of such payment.

     Section 3.09. Resale of the Securities. During the period of two years
after the last date of original issuance of the Securities, the Company shall
not, and shall not permit any of its Affiliates to, resell any of the Securities
or the shares of Common Stock, if any, issued upon conversion of the Securities,
that constitute "restricted securities" under Rule 144 under the Securities Act
that have been reacquired by any of them.

                                SUCCESSOR COMPANY

     Section 4.01. Consolidation, Merger and Sale of Assets. The Company shall
not, without the consent of the Holders, consolidate with, merge into or sell,
lease or otherwise transfer, in one transaction or a series of related
transactions, the consolidated assets of the Company and its Subsidiaries
substantially as an entirety to any corporation, limited liability company,
partnership or trust organized under the laws of the United States of America or
any of its political subdivisions, unless:

          (a) the resulting, surviving or transferee Person (the "SUCCESSOR
     COMPANY") if not the Company, shall be a corporation, partnership, trust or
     limited liability company organized and existing under the laws of the
     United States of America, any State thereof or the District of Columbia and
     the Successor Company (if not the Company) shall expressly assume by
     supplemental indenture, executed and delivered to the Trustee, in form
     satisfactory to the Trustee, all obligations of the Company under the
     Securities, the Indenture and, to the extent that it is otherwise still
     operative, the Registration Rights Agreement;

          (b) if as a result of such transaction the Securities become
     convertible into common stock or other securities issued by a third party,
     such third party fully and unconditionally guarantees all obligations of
     the Company or such successor under the Securities and the Indenture;

          (c) at the time of such transaction, no Event Of Default and no
     Default, shall have happened and be continuing; and

                                       33

<PAGE>

          (d) each Subsidiary Guarantor (unless it is the other party to the
     transactions described above, in which case clause (a) and Section 10.02
     shall apply) shall have by supplemental indenture confirmed that its
     Subsidiary Guarantee shall apply for such Person's obligations in respect
     of this Indenture and the Securities and its obligations under the
     Registration Rights Agreement shall continue to be in effect; and

          (e) an Officers' Certificate and an Opinion of Counsel, each stating
     that the consolidation, merger or transfer complies with the provisions of
     the Indenture, have been delivered to the Trustee.

     For purposes of this Section 4.01, the sale, lease, conveyance, assignment,
transfer, or other disposition of all or substantially all the properties and
assets of one or more Subsidiaries of the Company, which properties and assets,
if held by the Company instead of such Subsidiaries, would constitute all or
substantially all of the properties and assets of the Company on a consolidated
basis, shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company. The Successor Company will succeed to, and
be substituted for, and may exercise every right and power of, the Company under
this Indenture, but, in the case of a lease of all or substantially all its
assets, the Company will not be released from the obligation to pay the
principal of and interest (including any Contingent Interest and Liquidated
Damages) on the Securities.

                                    ARTICLE 5
                            REDEMPTION OF SECURITIES

     Section 5.01. Optional Redemption. (a) Prior to April 5, 2013, the
Securities shall not be redeemable. On and after April 5, 2013, the Securities
may be redeemed, as a whole or from time to time in part, subject to the
conditions set forth herein, at a price (the "REDEMPTION PRICE") equal to 100%
of the principal amount of Securities to be redeemed, plus accrued and unpaid
interest (including any Contingent Interest and Liquidated Damages) to, but
excluding, the Redemption Date; provided that if the Redemption Date occurs
after a Regular Record Date for the payment of interest and on or prior to the
related interest payment date, the Redemption Price for any such Securities to
be redeemed shall be 100% of the principal amount of such Securities plus the
full amount of accrued and unpaid interest (including any Contingent Interest
and Liquidated Damages) payable on such interest payment date, and shall be paid
to the Holder on such Regular Record Date.

     (b) Clean-Up Redemption. In addition, if at any time there is less than
$40,000,000 (or if the Initial Purchasers exercise their over-allotment option,
less than 10% of the aggregate principal amount of Securities originally issued,
up to $46,000,000) aggregate principal amount of the Securities outstanding at
such

                                       34

<PAGE>

time, the Company may, subject to the conditions set forth herein, redeem for
cash all the outstanding Securities at the Redemption Price.

     Section 5.02. Election to Redeem; Notice to Trustee. The election of the
Company to redeem any Securities pursuant to Section 5.01 shall be evidenced by
a Board Resolution. In case of any redemption at the election of the Company,
the Company shall, on or prior to the date that is 30 days prior to the date on
which notice is given to the Holders (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities to be redeemed and shall deliver to the
Trustee such documentation and records as shall enable the Trustee to select the
Securities to be redeemed pursuant to Section 5.03. Any such notice may be
cancelled at any time prior to notice of such redemption being mailed to any
Holder and shall thereby be void and of no effect.

     Section 5.03. Selection by Trustee of Securities to be Redeemed. If less
than all the Securities are to be redeemed at any time pursuant to an optional
redemption, the particular Securities to be redeemed shall be selected, not more
than 60 days prior to the Redemption Date by the Trustee, from the outstanding
Securities not previously called for redemption, by lot, or on a pro rata basis
among the classes of Securities or by such other method as the Trustee shall
deem fair and appropriate (and in such manner as is not prohibited by applicable
legal requirements) and which may provide for the selection for redemption of
portions of the principal of the Securities; provided, however, that no such
partial redemption shall reduce the portion of the principal amount of a
Security not redeemed to less than $1,000.

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

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

     If any Securities selected for partial redemption are thereafter
surrendered for conversion in part before termination of the conversion right
with respect to the portion of the Securities so selected, the converted portion
of such Securities shall be deemed (so far as may be), solely for purposes of
determining the aggregate principal amount of Securities to be redeemed by the
Company, to be the portion selected for redemption. Securities which have been
converted during a selection of Securities to be redeemed may be treated by the
Trustee as outstanding for the purpose of such selection. Nothing in this
Section 5.03 shall

                                       35

<PAGE>

affect the right of any Holder to convert any Securities pursuant to Article 12
before the termination of the conversion right with respect thereto.

     Section 5.04. Notice of Redemption. Notice of redemption shall be given in
the manner provided for in Section 14.02 not less than 30 nor more than 60 days
prior to the Redemption Date, to each Holder of Securities to be redeemed. The
Trustee shall give notice of redemption in the Company's name and at the
Company's expense; provided, however, that the Company shall deliver to the
Trustee, at least 60 days prior to the Redemption Date, an Officers' Certificate
requesting that the Trustee give such notice at the Company's expense and
setting forth the information to be stated in such notice as provided in (a)
through (k) in the following paragraph.

     All notices of redemption shall state:

     (a) the Redemption Date,

     (b) the Redemption Price payable as provided in Section 5.06, if any,

     (c) the then-current Conversion Rate, and provide a statement that the
Securities called for redemption may be converted at any time before the close
of business on the Business Day immediately preceding the Redemption Date, and
that Holders who wish to convert Securities must comply with the procedures in
paragraph 7 of the Securities,

     (d) if less than all outstanding Securities are to be redeemed, the
identification of the particular Securities (or portion thereof) to be redeemed,
as well as the aggregate principal amount of Securities to be redeemed and the
aggregate principal amount of Securities to be outstanding after such partial
redemption,

     (e) in case any Security is to be redeemed in part only, the notice which
relates to such Security shall state that on and after the Redemption Date, upon
surrender of such Security, the Holder will receive, without charge, a new
Security or Securities of authorized denominations for the principal amount
thereof remaining unredeemed,

     (f) that on the Redemption Date, the Redemption Price will become due and
payable upon each such Security, or the portion thereof, to be redeemed, and,
unless the Company defaults in making the redemption payment, that interest
(including any Contingent Interest and Liquidated Damages) on Securities called
for redemption (or the portion thereof) will cease to accrue on and after said
date,

     (g) the place or places where such Securities are to be surrendered for
payment of the Redemption Price,

                                       36

<PAGE>

     (h) the name and address of the Paying Agent and the Conversion Agent,

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

     (j) the CUSIP or ISIN number, and that no representation is made as to the
accuracy or correctness of the CUSIP or ISIN number, if any, listed in such
notice or printed on the Securities, and

     (k) the paragraph of the Securities pursuant to which the Securities are to
be redeemed.

     Section 5.05. Deposit of Redemption Price. Prior to any Redemption Date,
the Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 2.06) an amount of money sufficient to pay the Redemption
Price of all the Securities which are to be redeemed on that date other than
Securities or portions of Securities called for redemption that are beneficially
owned by the Company and have been delivered by the Company to the Trustee for
cancellation.

     Section 5.06. 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, and from and
after such date (unless the Company shall default in the payment of the
Redemption Price or accrued and unpaid interest (including any Contingent
Interest and Liquidated Damages)) such Securities shall cease to bear interest,
Contingent Interest or Liquidated Damages. 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.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal shall, until paid, bear interest
(including any Contingent Interest and Liquidated Damages) from the Redemption
Date at the rate borne by the Securities.

     Section 5.07. Securities Redeemed in Part. Any Security which is to be
redeemed only in part (pursuant to the provisions of this Article 5) shall be
surrendered at the office or agency of the Company maintained for such purpose
pursuant to Section 3.03 (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder's

Security at the expense of the Company, a new Security or Securities, of any
authorized denomination as requested by such Holder, in an aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered, provided that each such new Security will be in a
principal amount of $1,000 or integral multiple thereof.

                                    ARTICLE 6
                              DEFAULTS AND REMEDIES

Securities then outstanding;

     (e) failure by the Company to make any payment by the end of the applicable

a default with respect to such indebtedness without such indebtedness having
been discharged or such acceleration having been cured, waived, rescinded or

<PAGE>

     (g) failure by the Company to give timely notice of specified corporate
transactions and other specified events, as required under Section
12.01(a)(iii)(A);

     (h) the Company or any Significant Subsidiary pursuant to or within the
meaning of any Bankruptcy Law:

          (i) commences a voluntary case or proceeding;

          (ii) consents to the entry of judgment, decree or order for relief
     against it in an involuntary case or proceeding;

          (iii) consents to the appointment of a Custodian of it or for any
     substantial part of its property;

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

          (v) consents to or acquiesces in the institution of a bankruptcy or an
     insolvency proceeding against it;

          (vi) takes any corporate action to authorize or effect any of the
     foregoing; or

          (vii) takes any comparable action under any foreign laws relating to
     insolvency; or

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

          (i) is for relief against the Company or any Significant Subsidiary in
     an involuntary case;

          (ii) appoints a Custodian of the Company for all or substantially all
     of the Company's or any Significant Subsidiary's property; or

          (iii) orders the winding up or liquidation of the Company or
     Significant Subsidiary;

and, in each case, the order or decree or relief remains unstayed and in effect

     (j) except as permitted by this Indenture, any Subsidiary Guarantee shall
be held in any judicial proceeding to be unenforceable or invalid or shall cease
for any reason to be in full force and effect, or any Subsidiary Guarantor, or
any Person acting on its behalf, shall deny or disaffirm its obligation under
the Subsidiary Guarantee, unless, in each case, a replacement Subsidiary
Guarantee

                                       39

<PAGE>

by such Subsidiary Guarantor shall have been executed and delivered to the
Trustee in lieu thereof together with an Opinion of Counsel stating that such
Subsidiary Guarantee is enforceable, valid and in full force and effect.

     The foregoing will constitute Events of Default whatever the reason for any
such Event of Default and whether it is voluntary or involuntary or is effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.

     Section 6.02. Acceleration. If an Event of Default specified in Section
6.01(h) or (i) above occurs and is continuing, the principal of and accrued and
unpaid interest, if any, and Contingent Interest and Liquidated Damages, if any,
on all the Securities outstanding shall be immediately due and payable with no
further action by the Trustee or the Holders. If an Event of Default (other than
an Event of Default specified in Section 6.01(h) or (i) above) occurs and is
continuing, the Trustee by notice to the Company, or the Holders of at least 25%
in aggregate principal amount of the outstanding Securities by notice to the
Company and the Trustee, may, and the Trustee at the request of such Holders
shall, declare the principal of and accrued and unpaid interest, if any, and
Contingent Interest and Liquidated Damages, if any, on all the Securities to be
due and payable. Upon such a declaration, such principal, premium, if any, and
accrued and unpaid interest and Contingent Interest and Liquidated Damages, if
any, shall be due and payable immediately.

     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 of or interest (including any Contingent Interest and Liquidated
Damages) on the Securities or to enforce the performance of any provision of the
Securities or this Indenture.

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

     Section 6.04. Waiver of Past Defaults. The Holders of a majority in
aggregate principal amount of the outstanding Securities through their written
consent, or the Holders of a majority in aggregate principal amount of
outstanding Securities represented at a meeting at which a Quorum is present by
a written resolution, may (a) waive, by their consent (including, without
limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Securities), an existing Default or Event of Default and
its consequences except (i) a Default or Event of Default in the payment of the
principal of or

                                       40

<PAGE>

interest (including any Contingent Interest and Liquidated Damages) on a
Security, (ii) a Default or Event of Default in respect of the failure to
convert the Securities, or (iii) a Default or Event of Default in respect of a
provision that under Section 9.02 cannot be amended without the consent of each
Securityholder affected and (b) rescind and annul any such acceleration with
respect to the Securities and its consequences if (i) rescission would not
conflict with any judgment or decree of a court of competent jurisdiction and
(ii) all existing Events of Default, other than the nonpayment of the principal
of and interest (including any Contingent Interest and Liquidated Damages) on
the Securities that have become due solely by such declaration of acceleration,
have been cured or waived. When a Default or Event of Default is waived, it is
deemed cured, but no such waiver shall extend to any subsequent or other Default
or Event of Default or impair any consequent right. To the extent required for
the effectiveness of this Section 6.04, the provisions of Section 316(a)(1) of
the TIA are hereby excluded.

     Section 6.05. Control by Majority. The Holders of a majority in aggregate
principal amount of the outstanding Securities through their written consent, or
the Holders of a majority in aggregate principal amount of outstanding
Securities represented at a meeting at which a Quorum is present by a written
resolution, may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or of exercising any trust or power
conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture or, subject to Sections 7.01
and 7.02, that the Trustee determines is unduly prejudicial to the rights of
other Securityholders or would involve the Trustee in personal liability;
provided, however, that the Trustee may take any other action deemed proper by
the Trustee that is not inconsistent with such direction. To the extent required
for the effectiveness of this Section 6.05, the provisions of Section 316(a)(1)
of the TIA are hereby excluded.

     Section 6.06. Limitation on Suits. Subject to Section 6.07, a
Securityholder may not pursue any remedy with respect to this Indenture or the
Securities unless:

     (a) such Holder has previously given to the Trustee written notice stating
that an Event of Default is continuing;

     (b) Holders of at least 25% in principal amount of the outstanding
Securities have requested that the Trustee pursue the remedy;

     (c) such Holders have offered to the Trustee security or indemnity
reasonably satisfactory to it against any loss, liability or expense to be
incurred in compliance with such request;

                                       41

<PAGE>

     (d) the Trustee has not complied with such request within 60 days after
receipt of the request and the offer of security or indemnity; and

     (e) the Holders of a majority in principal amount of the outstanding
Securities have not given the Trustee a direction that, in the opinion of the
Trustee, is inconsistent with such request within such 60-day period.

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

     Section 6.07. Rights of Holders to Receive Payment. Notwithstanding any
other provision of this Indenture (including, without limitation, Section 6.06),
the right of any Holder to receive payment of principal of or interest
(including any Contingent Interest and Liquidated Damages) on the Securities
held by such Holder, on or after the respective due dates expressed in the
Securities, or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of
such Holder.

     Section 6.08. Collection Suit by Trustee. If an Event of Default specified
in clauses (a) or (b) of Section 6.01 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 then due and owing (together with interest on any
unpaid interest (including any Contingent Interest and Liquidated Damages) to
the extent lawful) and the amounts provided for in Section 7.07.

     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 (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel) and the Securityholders allowed in any judicial
proceedings relative to the Company, its Subsidiaries or its or their respective
creditors or properties and, unless prohibited by law or applicable regulations,
may be entitled and empowered to participate as a member of any official
committee of creditors appointed in such matter, and may vote on behalf of the
Holders in any election of a trustee in bankruptcy or other Person performing
similar functions, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and its counsel,
and any other amounts due to the Trustee under Section 7.07.

                                       42

<PAGE>

     Section 6.10. Priorities. If the Trustee collects any money or property
pursuant to this Article 6, it shall pay out the money or property in the
following order:

          FIRST: to the Trustee for amounts due under Section 7.07;

          SECOND: to Securityholders for amounts due and unpaid on the
     Securities for principal and interest (including any Contingent Interest
     and Liquidated Damages), ratably, without preference or priority of any
     kind, according to the amounts due and payable on the Securities for
     principal and interest, respectively; and

          THIRD: to the Company.

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

     Section 6.11. Restoration of Rights and Remedies. If the Trustee or any
Holder has instituted a proceeding to enforce any right or remedy under this
Indenture and the proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee or to the Holder, then, subject
to any determination in the proceeding, the Company, the Subsidiary Guarantors,
the Trustee, any Subsidiaries and the Holders will be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Company, any Subsidiary Guarantors, the Trustee, any
Subsidiaries and the Holders will continue as though no such proceeding had been
instituted.

     Section 6.12. Undertaking of Costs. In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as Trustee, a court in its discretion may require
the filing by any party litigant in the suit of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in
the suit, having due regard to the merits and good faith of the claims or
defenses made by the party litigant. This Section 6.12 does not apply to a suit
by the Trustee, a suit by the Company, a suit by a Holder pursuant to Section
6.07 or a suit by Holders of more than 10% in outstanding principal amount of
the Securities.

                                    TRUSTEE

     Section 7.01. Duties of Trustee. If to the knowledge of a Trust Officer,
an Event of Default has occurred and is continuing, the Trustee shall exercise
the rights and powers vested in it by this Indenture and use the same degree of
care and skill in its exercise as a prudent person would exercise or use under
the circumstances in the conduct of such person's own affairs; provided that if
an Event of Default occurs and is continuing, the Trustee will be under no
obligation to exercise any of the rights or powers under this Indenture at the
request or direction of any of the Holders unless such Holders have offered to
the Trustee reasonable indemnity or security satisfactory to it against loss,
liability or expense that might be incurred in compliance with such request or
direction.

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

          (i) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

          (ii) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates, opinions or orders
     furnished to the Trustee and conforming to the requirements of this
     Indenture. However, in the case of any such certificates, opinions or
     orders which by any provisions hereof are specifically required to be
     furnished to the Trustee, the Trustee shall examine such certificates and
     opinions to determine whether or not they conform to the requirements of
     this Indenture (but need not confirm or investigate the accuracy of
     mathematical calculations or other facts stated therein).

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

          (i) this paragraph does not limit the effect of paragraph (b) of this
     Section 7.01;

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

          (iii) 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.

                                       44

<PAGE>

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

     (e) The Trustee shall not be liable for interest on any money received by
it except as the Trustee may agree in writing with the Company.

     (f) Money held in trust by the Trustee need not be segregated from other
funds except to the extent required by law.

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

     (h) Every provision of this Indenture relating to the conduct or affecting
the liability of or affording protection to the Trustee shall be subject to the
provisions of this Section 7.01 and to the provisions of the TIA.

     (i) Unless otherwise specifically provided in this Indenture, any demand,
request, direction or notice from the Company shall be sufficient if signed by
an Officer of the Company.

     Section 7.02. Rights of Trustee. Subject to Section 7.01:

     (a) The Trustee may conclusively rely on any document (whether in its
original or facsimile form) reasonably believed by it to be genuine and to have
been signed or presented by the proper person. The Trustee need not investigate
any fact or matter stated in the document. The Trustee shall receive and retain
financial reports and statements of the Company as provided herein, but shall
have no duty to review or analyze such reports or statements to determine
compliance under covenants or other obligations of the Company.

     (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate and/or an Opinion of Counsel. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on an
Officers' Certificate or Opinion of Counsel.

     (c) The Trustee may act through its attorneys and agents and shall not be
responsible for the misconduct or negligence of any agent appointed with due
care.

     (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith which it believes to be authorized or within its rights or
powers, unless the Trustee's conduct constitutes negligence.

                                       45

<PAGE>

     (e) The Trustee may consult with counsel of its selection, and the advice
or opinion of counsel with respect to legal matters relating to this Indenture
and the Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

     (f) The Trustee shall not be responsible or liable for special, indirect,
or consequential loss or damage of any kind whatsoever (including, but not
limited to, loss of profit) resulting from actions taken in good faith and which
the Trustee believes to be authorized or within its rights or powers, unless the
Trustee's conduct constitutes willful misconduct or negligence.

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

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

     (i) The Trustee shall not be deemed to have notice of any Default or Event
of Default unless a Trust Officer has actual knowledge thereof or unless written
notice of any event which is in fact such a default is received by the Trustee
at the corporate trust office of the Trustee identified in Section 14.02, and
such notice references the Securities and this Indenture.

     (j) Unless the Trustee has knowledge of a Default or Event of Default, the
Trustee shall not be bound to ascertain or inquire as to the performance or
observance of any covenants, conditions or agreements on the part of the Company
under this Indenture; the Trustee may require full information and advice as to
the performance of the covenants, conditions and agreements aforesaid.

     (k) The Trustee shall not be required to give any bond or surety in respect
of the execution of the trusts and powers in respect of this Indenture.

     Section 7.03. Individual Rights of Trustee. The Trustee in its individual
or any other capacity may become the owner or pledgee of Securities and may
otherwise deal with the Company or its Affiliates with the same rights it would
have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or
co-

                                       46

<PAGE>

paying agent may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11. In addition, the Trustee shall be permitted to
engage in transactions with the Company; provided, however, that if the Trustee
acquires any "conflicting interest" (within the meaning of TIA Section 310(b)),
the Trustee must (i) eliminate such conflict within 90 days of acquiring such
conflicting interest, (ii) apply to the SEC for permission to continue acting as
Trustee or (iii) resign.

     Section 7.04. Trustee's Disclaimer. The Trustee shall not be responsible
for and makes no representation as to the validity or adequacy of this Indenture
or the Securities, shall not be accountable for the Company's use of the
proceeds from the Securities, shall not be responsible for the use or
application of any money received by any Paying Agent other than the Trustee and
shall not be responsible for any statement of the Company in this Indenture or
in any document issued in connection with the sale of the Securities or in the
Securities other than the Trustee's certificate of authentication.

     Section 7.05. Notice of Defaults. If a Default or Event of Default occurs
and is continuing and if a Trust Officer of the Trustee has actual knowledge
thereof, the Trustee shall mail by first class mail to each Securityholder at
the address set forth in the Securities Register notice of the Default or Event
of Default within 90 days after it occurs. Except in the case of a Default or
Event of Default in payment of principal of or interest (including any
Contingent Interest and Liquidated Damages) on any Security (including payments
pursuant to the optional redemption or required repurchase provisions of such
Security, if any), the Trustee may withhold such notice if and so long as its
board of directors, a committee of its board of directors or a committee of its
trust officers in good faith determines that withholding such notice is in the
best interest of Securityholders.

     Section 7.06. Reports by Trustee to Holders. As promptly as practicable
after each May 15 beginning with the May 15 following the date of this
Indenture, and in any event prior to July 1 in each year, the Trustee shall mail
to each Securityholder a brief report dated as of such May 15 that complies with
TIA Section 313(a), if required by such TIA Section 313(a). The Trustee also
shall comply with TIA Section 313(b). The Trustee shall also transmit by mail
all reports required by TIA Section 313(c).

     Section 7.07. Compensation and Indemnity. The Company shall pay to the
Trustee from time to time such compensation for its acceptance of this Indenture
and services hereunder as the Company and the Trustee shall from time to time
agree in writing. The Trustee's compensation shall not be limited by any law on
compensation of a trustee of an express trust. In addition to the compensation,
the Company shall reimburse the Trustee upon request for all reasonable
out-of-pocket expenses incurred or made by it. Such expenses shall

                                       47

<PAGE>
include the reasonable compensation and out-of-pocket expenses, disbursements
and advances of the Trustee's agents, counsel, accountants and experts within 30
days after receiving request therefor. The Company and the Subsidiary Guarantors
shall jointly and severally indemnify the Trustee against any and all loss,
liability, damages, claims or expense (including reasonable attorneys' fees and
expenses) incurred by it in connection with the administration of this trust and
the performance of its duties hereunder, except to the extent any such loss,
liability or expense shall be determined to have been caused by its own
negligence or bad faith, including the costs and expenses of enforcing this
Indenture (including this Section 7.07) and of defending itself against any
claims (whether asserted by any Securityholder, the Company or otherwise). 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 and the
Trustee shall provide reasonable cooperation at the Company's expense in the
defense. The Trustee may have separate counsel and the Company shall pay the
fees and expenses of such counsel, provided that the Company shall not be
required to pay such fees and expenses if it assumes the Trustee's defense,
unless, in the reasonable judgment of outside counsel to the Trustee, there is a
conflict of interest between the Company and the Trustee in connection with such
defense. The Company need not reimburse any expense or indemnify against any
loss, liability or expense incurred by the Trustee through the Trustee's own
willful misconduct, negligence or bad faith.

     To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest (including any Contingent Interest and Liquidated
Damages) on particular Securities. Such lien shall survive the satisfaction and
discharge of this Indenture. The Trustee's right to receive payment of any
amounts due under this Section 7.07 shall not be subordinate to any other
unsecured liability or debt of the Company.

     The Company's payment obligations pursuant to this Section 7.07 shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in clauses (h) or (i) of Section 6.01 with
respect to the Company, the expenses are intended to constitute expenses of
administration under any Bankruptcy Law.

     Section 7.08. Replacement of Trustee. The Trustee may resign at any time by
so notifying the Company. The Holders of a majority in aggregate principal
amount of the Securities may remove the Trustee by so notifying the Trustee and
may appoint a successor Trustee. The Company shall remove the Trustee if:

                                       48

<PAGE>

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

     (b) the Trustee is adjudged bankrupt or insolvent;

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

     (d) the Trustee otherwise becomes incapable of acting.

     If the Trustee resigns or is removed by the Company or by the Holders of a
majority in aggregate principal amount of the Securities and such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the
office of the Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Company shall promptly appoint 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
Securityholders. The retiring Trustee shall promptly transfer all property held
by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.07.

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

     If the Trustee fails to comply with Section 7.10, unless the Trustee's duty
to resign is stayed as provided in TIA Section 310(b), any Securityholder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

     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.

     Section 7.09. Successor Trustee by Merger. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

     In case at the time such successor or successors by merger, conversion or
consolidation to the Trustee shall succeed to the trusts created by this
Indenture,

                                       49

any of the Securities shall have been authenticated but not delivered, any such
successor to the Trustee may adopt the certificate of authentication of any
predecessor trustee, and deliver such Securities so authenticated; and in case
at that time any of the Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor to the Trustee;
provided that the right to adopt the certificate of authentication of any
predecessor Trustee or authenticate Securities in the name of any predecessor
Trustee shall only apply to its successor or successors by merger, consolidation
or conversion.

     Section 7.10. Eligibility; Disqualification. The Trustee shall at all times
satisfy the requirements of TIA Section 310(a). The Trustee, together with its
affiliates, shall have a combined capital and surplus of at least $50 million as
set forth in its most recent published annual report of condition. The Trustee
shall comply with TIA Section 310(b); provided, however, that there shall be
excluded from the operation of TIA Section 310(b)(1) any indenture or indentures
under which other securities or certificates of interest or participation in
other securities of the Company are outstanding if the requirements for such
exclusion set forth in TIA Section 310(b)(1) are met.

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

application by the Trustee for written instructions from the Company may, at the
option of the Trustee, set forth in writing any action proposed to be taken or
omitted by the Trustee under this Indenture and the date on and/or after which
such action shall be taken or such omission shall be effective. The Trustee
shall not be liable for any action taken by, or omission of, the Trustee in
accordance with a proposal included in such application on or after the date
specified in such application (which date shall not be less than three Business
Days after the date any officer of the Company actually receives such
application, unless any such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.

                             DISCHARGE OF INDENTURE

     Section 8.01. Discharge of Liability on Securities. When (1) the Company
shall deliver to the Registrar for cancellation all Securities theretofore

stolen and in lieu of or in substitution for which other Securities shall have
been authenticated and delivered) and not theretofore canceled, or (2) all the
Securities not theretofore canceled or delivered to the Registrar for
cancellation shall have (a) been deposited for conversion (after all related
Conversion Periods have elapsed) and the Company shall deliver to the Holders
cash and shares of Common Stock, as applicable, sufficient to pay all amounts
owing in respect of all Securities (other than any Securities which shall have
been mutilated, destroyed, lost or stolen and in lieu of or in substitution for
which other Securities shall have been authenticated and delivered) not
theretofore canceled or delivered to the Registrar for cancellation or (b)
become due and payable on the Stated Maturity, Purchase Date, Fundamental Change
Purchase Date or Redemption Date, as applicable, and the Company shall deposit
with the Trustee cash or shares of Common Stock, as applicable, sufficient to
pay all amounts owing in respect of all Securities (other than any Securities
which shall have been mutilated, destroyed, lost or stolen and in lieu of or in
substitution for which other Securities shall have been authenticated and
delivered) not theretofore canceled or delivered to the Registrar for
cancellation, including the principal amount and any interest (including any
Contingent Interest and Liquidated Damages) accrued and unpaid to such Stated
Maturity, Purchase Date, Fundamental Change Purchase Date or Redemption Date, as
the case may be, and if in either case (1) or (2) the Company shall also pay or
cause to be paid all other sums payable hereunder by the Company, then this
Indenture with respect to the Securities shall cease to be of further effect
(except as to (i) remaining rights of registration of transfer, substitution and
exchange and conversion of Securities; (ii) rights hereunder of Holders to
receive payments of the amounts then due, including any interest (including any
Contingent Interest and Liquidated Damages) with respect to the Securities and
the other rights, duties and obligations of Holders, as beneficiaries hereof
with respect to the amounts, if any, so deposited with the Trustee; and (iii)
the rights, obligations and immunities of the Trustee, Authenticating Agent,
Paying Agent, Conversion Agent and Registrar under this Indenture with respect
to the Securities), and the Trustee, on demand of the Company accompanied by an
Officers' Certificate and an Opinion of Counsel as required by Section 8.03 and
at the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture with respect to the
Securities; the Company, however, hereby agrees to reimburse the Trustee,
Authenticating Agent, Paying Agent, Conversion Agent and Registrar for any costs
or expenses thereafter reasonably and properly incurred by the Trustee,
Authenticating Agent, Paying Agent, Conversion Agent and Registrar and to
compensate the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and
Registrar for any services thereafter reasonably and properly rendered by the
Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar in
connection with this Indenture with respect to the Securities.

                                       51

     Section 8.02. Reinstatement. If the Trustee or the Paying Agent is unable
to apply any money to the Holders entitled thereto 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 with respect to the Securities and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.01 until such
time as the Trustee or the Paying Agent is permitted to apply all such money in
accordance with this Indenture and the Securities to the Holders entitled
thereto; provided, however, that if the Company makes any payment of principal
amount of or interest (including any Contingent Interest and Liquidated Damages)
on any Securities following the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Holders of such Securities to receive
such payment from the money held by the Trustee or Paying Agent.

     Section 8.03. Officers' Certificate; Opinion of Counsel. Upon any
application or demand by the Company to the Trustee to take any action under
Section 8.01, the Company shall furnish to the Trustee an Officers' Certificate
stating that all conditions precedent, if any, provided for in this Indenture
relating to the proposed action have been complied with, and an Opinion of
Counsel stating that, in the opinion of such counsel, all such conditions
precedent have been complied with.

                                   ARTICLE 9
                                   AMENDMENTS

     Section 9.01. Without Consent of Holders. The Company, the Subsidiary
Guarantors and the Trustee may modify or amend this Indenture or the Securities
without notice to or consent of any Securityholder to:

     (a) add to the Company's covenants for the benefit of the Holders;

     (b) add a guarantor or other security for the benefit of the Holders;

     (c) release a Subsidiary Guarantor from all its obligations under its
Subsidiary Guarantee in the event of its sale, consolidation, dissolution or

change of the Common Stock or any consolidation, merger or sale of the

                                       52

<PAGE>

consolidated assets of the Company and its Subsidiaries substantially as an
entirety occurs, as provided in Section 12.04;

     (g) provide for the assumption of the Company's obligations to the Holders
in the case of a merger, consolidation, conveyance, sale, transfer or lease;

     (h) increase the Conversion Rate in the manner described herein;

the qualification of the Indenture under the TIA;

     (j) make any changes or modifications to the Indenture necessary in
connection with the registration of the Securities under the Securities Act, as
contemplated by the Registration Rights Agreement, provided that this action
does not adversely affect the interests of the Holders in any material respect;
or

     (k) cure any ambiguity or correct or supplement any defective provision
contained in the Indenture; provided that such modification or amendment does
not, in the good faith opinion of the Company's Board of Directors and the
Trustee, adversely affect the interests of the Holders in any material respect;
provided further that any amendment made solely to conform the provisions of the
indenture to the "DESCRIPTION OF THE NOTES" section of the Offering Memorandum
will not be deemed to adversely affect the interests of the Holders; or

     (l) add or modify any other provisions which the Company and the Trustee
may deem necessary or desirable and which will not adversely affect the
interests of the Holders.

     After an amendment under this Section 9.01 becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section 9.01.

     Section 9.02. With Consent of Holders. Modifications and amendments to this
Indenture or the Securities may be made by the Company, the Subsidiary
Guarantors and the Trustee, and noncompliance by the Company with any provision
of this Indenture or the Securities may be waived, either:

          (i) with the written consent of the Holders of at least a majority in
     aggregate principal amount of the Securities then outstanding (including,
     without limitation, consents obtained in connection with a purchase of, or
     tender offer or exchange offer for, Securities); or

                                       53

<PAGE>

          (ii) by the adoption of a resolution at a meeting of holders at which
     a Quorum is present by at least a majority in aggregate principal amount of
     the Securities then outstanding represented at such meeting (including,
     without limitation, consents obtained in connection with a purchase of, or
     tender offer or exchange offer for, Securities). To the extent required for
     the effectives of this Section 9.02, the provisions of Section 316(a)(1) of
     the TIA are hereby excluded. However, without the written consent or the
     affirmative vote of each Securityholder affected, an amendment or waiver
     may not:

               (A) change the maturity of the principal of or any installment of
          interest on any Security (including any payment of Contingent Interest
          and Liquidated Damages);

               (B) reduce the principal amount of, or any premium, if any, on
          any Security;

               (C) reduce the interest rate or amount of interest (including any
          Contingent Interest and Liquidated Damages) on any Security;

               (D) change the currency of payment of principal of, premium, if
          any, or interest on any Security;

               (E) impair the right to institute suit for the enforcement of any
          payment on or with respect to, or the conversion of, any Security;

               (F) except as otherwise permitted or contemplated by provisions
          of the Indenture concerning specified reclassifications or corporate
          reorganizations, impair or adversely affect the conversion rights of
          holders of the Securities, including any change to the payment of the
          principal return, the amount of net shares or net cash;

               (G) adversely affect any repurchase option of holders;

               (H) modify the redemption provisions in Article 5 of this
          Indenture in a manner adverse to the holders of Securities;

               (I) reduce the percentage in aggregate principal amount of
          Securities outstanding necessary to modify or amend this Indenture or
          to waive any past Default or Event of Default; or

                                       54

<PAGE>

               (J) reduce the percentage in aggregate principal amount of
          Securities outstanding required for any other waiver under this
          Indenture.

     It shall not be necessary for the consent of the Holders under this Section
9.02 to approve the particular form of any proposed amendment or waiver, but it
shall be sufficient if such consent approves the substance thereof. A consent to
any amendment or waiver under this Indenture by any Holder of the Securities
given in connection with a tender or exchange of such Holder's Securities will
not be rendered invalid by such tender or exchange.

     After an amendment under this Section 9.02 becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section 9.02.

     Section 9.03. Compliance with Trust Indenture Act. Every amendment to this
Indenture or the Securities shall comply with the TIA as then in effect.

     Section 9.04. Revocation and Effect of Consents and Waivers. A consent to
an amendment or a waiver by a Holder of a Security shall bind the Holder and
every subsequent Holder of that Security or portion of the Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent or waiver as to such Holder's Security
or portion of the Security if the Trustee receives the notice of revocation
before the date the amendment or waiver becomes effective or otherwise in
accordance with any related solicitation documents. After an amendment or waiver
becomes effective, it shall bind every Securityholder. An amendment or waiver
shall become effective upon receipt by the Trustee of the requisite number of
written consents under Section 9.01 or 9.02, as applicable.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Securityholders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Securityholders at such
record date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date. No such consent shall become valid or effective more than 120
days after such record date.

                                       55

<PAGE>

     Section 9.05. Notation on or Exchange of Securities. If an amendment
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company,
in exchange for the Security, shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

     Section 9.06. Trustee to Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article 9 (other than clause (k) and (l)
of Section 9.01) if the amendment does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may but need
not sign it. The Trustee shall not be obligated to sign any amendment pursuant
clause (k) and (l) of Section 9.01 unless it has the requisite good faith
opinion pursuant to clause (k) or determination pursuant to clause (l). In
signing such amendment the Trustee shall be provided with indemnity reasonably
satisfactory to it and to receive, and (subject to Sections 7.01 and 7.02) shall
be fully protected in relying upon, an Officers' Certificate and an Opinion of
Counsel stating that such amendment is authorized or permitted by this Indenture
and that such amendment is the legal, valid and binding obligation of the
Company and any Subsidiary Guarantors, enforceable against them in accordance
with its terms, subject to customary exceptions, and complies with the
provisions hereof (including, without limitation, Section 9.03).

                                   ARTICLE 10
                              SUBSIDIARY GUARANTEE

     Section 10.01. Subsidiary Guarantee. Each Subsidiary Guarantor hereby
fully, unconditionally and irrevocably guarantees, as primary obligor and not
merely as surety, jointly and severally with each other Subsidiary Guarantor, to
each Holder of the Securities and the Trustee, the full and punctual payment
when due, whether at maturity, by acceleration, by redemption or otherwise, of
the principal of and interest, including any Contingent Interest or Liquidated
Damages, on the Securities and all other obligations and liabilities of the
Company under this Indenture (including without limitation interest (including
any Contingent Interest or Liquidated Damages) accruing after the filing of any
petition in bankruptcy, or the commencement of any insolvency, reorganization or
like proceeding, relating to the Company or any Subsidiary Guarantor whether or
not a claim for post-filing or post-petition interest is allowed in such
proceeding) (all the foregoing being hereinafter collectively called the
"OBLIGATIONS"). Each Subsidiary Guarantor further agrees (to the extent
permitted by law) that the Obligations may be extended or renewed, in whole or
in part, without notice or

                                       56

<PAGE>

further assent from it, and that it will remain bound under this Article 10
notwithstanding any extension or renewal of any Obligation.

     Each Subsidiary Guarantor waives presentation to, demand of payment from
and protest to the Company of any of the Obligations and also waives notice of
protest for nonpayment. Each Subsidiary Guarantor waives notice of any default
under the Securities or the Obligations. The obligations of each Subsidiary
Guarantor hereunder shall not be affected by (a) the failure of any Holder to
assert any claim or demand or to enforce any right or remedy against the Company
or any other person under this Indenture, the Securities or any other agreement
or otherwise; (b) any extension or renewal of any thereof; (c) any rescission,
waiver, amendment or modification of any of the terms or provisions of this
Indenture, the Securities or any other agreement; (d) the release of any
security held by any Holder or the Trustee for the Obligations or any of them;
(e) the failure of any Holder to exercise any right or remedy against any other
Subsidiary Guarantor; or (f) any change in the ownership of the Company.

     Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee
herein constitutes a Guarantee of payment when due (and not a Guarantee of
collection) and waives any right to require that any resort be had by any Holder
to any security held for payment of the Obligations.

     The obligations of each Subsidiary Guarantor hereunder shall not be subject
to any reduction, limitation, impairment or termination for any reason (other
than payment of the Obligations in full), including any claim of waiver,
release, surrender, alteration or compromise, and shall not be subject to any
defense of setoff, counterclaim, recoupment or termination whatsoever or by
reason of the invalidity, illegality or unenforceability of the Obligations or
otherwise. Without limiting the generality of the foregoing, the obligations of
each Subsidiary Guarantor herein shall not be (to the extent permitted by law)
discharged or impaired or otherwise affected by the failure of any Holder to
assert any claim or demand or to enforce any remedy under this Indenture, the
Securities or any other agreement, by any waiver or modification of any thereof,
by any default, failure or delay, willful or otherwise, in the performance of
the Obligations, or by any other act or thing or omission or delay to do any
other act or thing which may or might in any manner or to any extent vary the
risk of any Subsidiary Guarantor or would otherwise operate as a discharge of
such Subsidiary Guarantor as a matter of law or equity.

     Each Subsidiary Guarantor agrees that its Subsidiary Guarantee herein shall
remain in full force and effect until payment in full of all the Obligations or
until such Subsidiary Guarantor is released from its Subsidiary Guarantee upon
the merger or the sale of all the Capital Stock or assets of the Subsidiary
Guarantor in compliance with Section 10.02. Each Subsidiary Guarantor further
agrees that its Subsidiary Guarantee herein shall continue to be effective or be

                                       57

<PAGE>

reinstated, as the case may be, if at any time payment, or any part thereof, of
principal of or interest (including any Contingent Interest and Liquidated
Damages), on any of the Obligations is rescinded or must otherwise be restored
by any Holder upon the bankruptcy or reorganization of the Company or otherwise.

     In furtherance of the foregoing and not in limitation of any other right
which any Holder has at law or in equity against any Subsidiary Guarantor by
virtue hereof, upon the failure of the Company to pay any of the Obligations
when and as the same shall become due, whether at maturity, by acceleration, by
redemption or otherwise, each Subsidiary Guarantor hereby promises to and will,
upon receipt of written demand by the Trustee, forthwith pay, or cause to be
paid, in cash, to the Holders an amount equal to the sum of (i) the unpaid
amount of such Obligations then due and owing and (ii) accrued and unpaid
interest (including any Contingent Interest and Liquidated Damages) on such
Obligations then due and owing (but only to the extent not prohibited by law).

     Each Subsidiary Guarantor further agrees that, as between such Subsidiary
Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity
of the Obligations guaranteed hereby may be accelerated as provided in this
Indenture for the purposes of its Subsidiary Guarantee herein, notwithstanding
any stay, injunction or other prohibition preventing such acceleration in
respect of the Obligations guaranteed hereby and (y) in the event of any such
declaration of acceleration of such Obligations, such Obligations (whether or
not due and payable) shall forthwith become due and payable by the Subsidiary
Guarantor for the purposes of this Subsidiary Guarantee.

     Each Subsidiary Guarantor also agrees to pay any and all reasonable costs
and expenses (including reasonable attorneys' fees and expenses) incurred by the
Trustee in enforcing any rights under this Section 10.01.

     Section 10.02. Limitation on Liability; Termination, Release and Discharge
Upon Merger or Consolidation; Termination on Conversion. (a) The obligations of
each Subsidiary Guarantor hereunder will be limited to the maximum amount as
will, after giving effect to all other contingent and fixed liabilities of such
Subsidiary Guarantor (including, without limitation, any guarantees under the
Senior Credit Facility) and after giving effect to any collections from or
payments made by or on behalf of any other Subsidiary Guarantor in respect of
the obligations of such other Subsidiary Guarantor under its Subsidiary
Guarantee or pursuant to its contribution obligations under this Indenture,
result in the obligations of such Subsidiary Guarantor under its Subsidiary
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under
federal or state law and not otherwise being void or voidable under any similar
laws affecting the rights of creditors generally.

                                       58

<PAGE>

     (b) Each Subsidiary Guarantor may consolidate with or merge into or sell
its assets to the Company or another Subsidiary Guarantor without limitation.
Subject to Section 3.04 and Article 4, each Subsidiary Guarantor may (i) sell or
otherwise dispose (including by way of merger or consolidation), in one or more
series of related transactions, of a majority or more of the total voting power
of the Capital Stock or other interests of such Subsidiary Guarantor, or (ii)
sell or otherwise dispose all or substantially all of such Subsidiary
Guarantor's assets; provided that if the surviving Person of any such merger or
consolidation is the Company or an Affiliate of the Company, or any such sale is
to the Company or an Affiliate of the Company, such merger, consolidation or
sale shall not be permitted unless:

               (A) the Person formed by or surviving any such consolidation or
          merger or to whom such sale is made is a corporation, partnership,
          trust or limited liability company organized existing under the laws
          of the United States of America, any State thereof or the District of
          Columbia and assumes all the obligations of such Subsidiary under the
          Subsidiary Guarantee pursuant to a supplemental indenture in form and
          substance reasonably satisfactory to the Trustee in respect of the
          Securities, this Indenture and the Subsidiary Guarantee,

               (B) immediately after giving effect to such transaction, no
          Default or Event of Default exists; and

               (C) the Company delivers to the Trustee an Officers' Certificate
          and an Opinion of Counsel addressed to the Trustee with respect to the
          foregoing matters.

Upon the sale or disposition of a Subsidiary Guarantor (by merger,
consolidation, the sale of its Capital Stock or the sale of all or substantially
all of its assets (other than by lease)), which sale or disposition is otherwise
in compliance with this Indenture, such Subsidiary Guarantor will be released
from all its obligations under this Indenture and its Subsidiary Guarantee will
terminate. Each Subsidiary Guarantee with respect to a Security will
automatically terminate immediately prior to such Security's conversion.

     (c) Each Subsidiary Guarantor will be deemed released from all its
obligations under this Indenture, its Subsidiary Guarantee and the Registration
Rights Agreement and such Subsidiary Guarantee will terminate upon the discharge
of the Securities pursuant to the provisions of Article 8 hereof.

     Section 10.03. Right of Contribution. Each Subsidiary Guarantor hereby
agrees that to the extent that any Subsidiary Guarantor shall have paid more
than its proportionate share of any payment made on the obligations under the

                                       59

<PAGE>

Subsidiary Guarantees, such Subsidiary Guarantor shall be entitled to seek and
receive contribution from and against any other Subsidiary Guarantor's pro rata
portion of such payment based on the respective net assets of all the Subsidiary
Guarantors at the time of such payment determined in accordance with GAAP. The
provisions of this Section 10.03 shall in no respect limit the obligations and
liabilities of each Subsidiary Guarantor to the Trustee and the Holders and each
Subsidiary Guarantor shall remain liable to the Trustee and the Holders for the
full amount guaranteed by such Subsidiary Guarantor hereunder.

     Section 10.04. No Subrogation. Notwithstanding any payment or payments made
by each Subsidiary Guarantor hereunder, no Subsidiary Guarantor shall be
entitled to be subrogated to any of the rights of the Trustee or any Holder
against the Company or any other Subsidiary Guarantor or any collateral security
or guarantee or right of offset held by the Trustee or any Holder for the
payment of the Obligations, nor shall any Subsidiary Guarantor seek or be
entitled to seek any contribution or reimbursement from the Company or any other
Subsidiary Guarantor in respect of payments made by such Subsidiary Guarantor
hereunder, until all amounts owing to the Trustee and the Holders by the Company
on account of the Obligations are paid in full. If any amount shall be paid to
any Subsidiary Guarantor on account of such subrogation rights at any time when
all of the Obligations shall not have been paid in full, such amount shall be
held by such Subsidiary Guarantor in trust for the Trustee and the Holders,

                    CHANGE; PURCHASE AT THE OPTION OF HOLDERS

     Section 11.01. Purchase at the Option of the Holder Upon a Fundamental
Change. If a Fundamental Change shall occur at any time, each Holder shall have
the right, at such Holder's option, to require the Company to purchase any or
all of such Holder's Securities on a date specified by the Company that is not
less than 20 nor more than 35 business days after the date of the Company Notice
of the occurrence of such Fundamental Change (subject to extension to comply
with applicable law, as provided in Section 11.03(d)) (the "FUNDAMENTAL CHANGE

PURCHASE DATE"). The Securities shall be repurchased in integral multiples of
$1,000 of the principal amount. The Company shall purchase such Securities at a
price (the "FUNDAMENTAL CHANGE PURCHASE PRICE"), which shall be paid in cash,
equal to 100% of the principal amount of the Securities to be purchased plus any
accrued and unpaid interest, including any Contingent Interest and Liquidated
Damages, to but excluding the Fundamental Change Purchase Date, unless the
Fundamental Change Purchase Date is between a Regular Record Date and the
interest payment date to which it relates, in which case the Fundamental Change
Purchase Price shall equal 100% of the principal amount of Securities to be
purchased plus accrued and unpaid interest, including any Contingent Interest
and Liquidated Damages, payable on such interest payment date, and such accrued
and unpaid interest, including any Contingent Interest and Liquidated Damages,
shall be paid to the Holder of record on the Regular Record Date.

     (a) Notice of Fundamental Change. The Company, or at its request (which
must be received by the Paying Agent at least three Business Days (or such
lesser period as agreed to by the Paying Agent) prior to the date the Paying
Agent is requested to give such notice as described below) the Paying Agent, in
the name of and at the expense of the Company, shall mail to all Holders and the
Trustee a Company Notice of the occurrence of a Fundamental Change and of the
purchase right arising as a result thereof, including the information required
by Section 11.03(a) hereof, on or before the 25th calendar day after the
occurrence of such Fundamental Change. The Company shall promptly furnish to the
Paying Agent a copy of such Company Notice.

     (b) Exercise of Option. For a Security to be so purchased at the option of
the Holder, the Paying Agent must receive such Security duly endorsed for
transfer, together with a written notice of purchase (a "FUNDAMENTAL CHANGE
PURCHASE NOTICE") in the form entitled "Form of Fundamental Change Purchase
Notice" attached to the Security duly completed, on or before the third Business
Day immediately preceding the Fundamental Change Purchase Date, subject to
extension to comply with applicable law. The Fundamental Change Purchase Notice
shall state:

          (i) if certificated, the certificate numbers of the Securities which
     the Holder shall deliver to be purchased;

          (ii) the portion of the principal amount of the Securities which the
     Holder shall deliver to be purchased, which portion must be $1,000 in
     principal amount or an integral multiple thereof; and

          (iii) that such Securities shall be purchased as of the Fundamental
     Change Purchase Date pursuant to the terms and conditions specified in
     paragraph 6 of the Securities and in this Indenture.

                                       61

<PAGE>

     (c) Procedures. The Company shall purchase from a Holder, pursuant to this
Section 11.01, Securities if the principal amount of such Securities requested
to be purchased by such Holder is $1,000 or an integral multiple of $1,000.

     Any purchase by the Company contemplated pursuant to the provisions of this
Section 11.01 shall be consummated by the delivery of the Fundamental Change
Purchase Price to be received by the Holder promptly following the later of the
Fundamental Change Purchase Date or the time of book-entry transfer or delivery
of the Securities.

     Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent the Fundamental Change Purchase Notice contemplated by this
Section 11.01 shall have the right at any time prior to the close of business on
the third Business Day prior to the Fundamental Change Purchase Date to withdraw
such Fundamental Change Purchase Notice (in whole or in part) by delivery of a
written notice of withdrawal to the Paying Agent in accordance with Section
11.03(b).

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

     On or before 11:00 a.m. (New York City time) on the Fundamental Change
Purchase Date, the Company shall deposit with the Paying Agent (or if the
Company or an Affiliate of the Company is acting as the Paying Agent, shall
segregate and hold in trust) cash sufficient to pay the aggregate Fundamental
Change Purchase Price of the Securities to be purchased pursuant to this Section
11.01. Payment by the Paying Agent of the Fundamental Change Purchase Price for
such Securities shall be made promptly following the later of the Fundamental
Change Purchase Date or the time of book-entry transfer or delivery of such
Securities. Subject to Section 12.02 herein, no payment or adjustment shall be
made for dividends on the Common Stock the record date for which occurred on or
prior to the Fundamental Change Purchase Date. If the Paying Agent holds, in
accordance with the terms of this Indenture, cash sufficient to pay the
Fundamental Change Purchase Price of such Securities on the Fundamental Change
Purchase Date, then, on and after the Business Day following such Fundamental
Change Purchase Date, such Securities shall cease to be outstanding and interest
(including any Contingent Interest and Liquidated Damages), on such Securities
shall cease to accrue, whether or not book-entry transfer of such Securities is
made or such Securities are delivered to the Paying Agent, and all other rights
of the Holder shall terminate (other than the right to receive the Fundamental
Change Purchase Price and previously accrued and unpaid interest (including any
Contingent Interest and Liquidated Damages), upon delivery or

                                       62

transfer of the Securities). Nothing herein shall preclude any withholding tax
required by law.

     The Company shall require each Paying Agent (other than the Trustee) to
agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all cash held by the Paying Agent for the payment of the
Fundamental Change Purchase Price and shall notify the Trustee of any default by
the Company in making any such payment. If the Company or an Affiliate of the
Company acts as Paying Agent, it shall segregate the cash held by it as Paying
Agent and hold it as a separate trust fund. The Company at any time may require
a Paying Agent to deliver all cash held by it to the Trustee and to account for
any funds disbursed by the Paying Agent. Upon doing so, the Paying Agent shall
have no further liability for the cash delivered to the Trustee.

     Section 11.02. Purchase of Securities at the Option of the Holder.

     (a) Securityholders have the right to require the Company to purchase for
cash on each of April 1, 2013, April 1, 2016 and April 1, 2021 (each, a
"PURCHASE DATE"), at a price (the "PURCHASE PRICE"), which shall be paid in
cash, equal to 100% of the principal amount of the Securities to be repurchased
plus any accrued and unpaid interest, including any Contingent Interest and
Liquidated Damages, to but excluding the Purchase Date (provided that the
Company will pay the full amount of accrued and unpaid interest (including any
Contingent Interest and Liquidated Damages) payable on an interest payment date
to the Holder of record at the close of business on the corresponding record
date) a Holder shall have the option to require the Company to purchase any
outstanding Securities, upon:

          (i) delivery to the Paying Agent by the Holder of a written notice of
     purchase (a "PURCHASE NOTICE") at any time from the opening of business on
     the date that is 23 Business Days prior to the relevant Purchase Date until
     the close of business on the third Business Day prior to such Purchase
     Date, stating:

               (A) if certificated, the certificate numbers of the Securities
          which the Holder will deliver to be purchased, or, if not
          certificated, the Purchase Notice must comply with appropriate DTC
          procedures;

               (B) the portion of the principal amount of the Securities which
          the Holder will deliver to be purchased, which portion must be $1,000
          in principal amount or an integral multiple thereof; and

                                       63
<PAGE>

               (C) that such Securities shall be purchased as of the Purchase
          Date pursuant to the terms and conditions specified in paragraph 6 of
          the Securities and in this Indenture;

          (ii) delivery or book-entry transfer of such Securities to the Paying
     Agent (together with all necessary endorsements) at the offices of the
     Paying Agent, such delivery or transfer being a condition to receipt by the
     Holder of the Purchase Price therefor; provided, however, that such
     Purchase Price shall be so paid pursuant to this Section 11.02 only if the
     Securities so delivered or transferred to the Paying Agent shall conform in
     all respects to the description thereof in the related Purchase Notice.

     (b) The Company shall purchase from a Holder, pursuant to this Section
11.02, Securities if the principal amount of such Securities requested to be
purchased by such Holder is $1,000 or an integral multiple of $1,000.

     (c) Any purchase by the Company contemplated pursuant to the provisions of
this Section 11.02 shall be consummated by the delivery of the Purchase Price to
be received by the Holder promptly following the later of the Purchase Date or
the time of book-entry transfer or delivery of the Securities.

     (d) Notwithstanding anything herein to the contrary, any Holder delivering
to the Paying Agent the Purchase Notice contemplated by this Section 11.02 shall
have the right at any time prior to the close of business on the Business Day
prior to the Purchase Date to withdraw such Purchase Notice (in whole or in
part) by delivery of a written notice of withdrawal to the Paying Agent in
accordance with Section 11.03(b).

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

     (f) On or before 11:00 a.m. (New York City time) on the Purchase Date, the
Company shall deposit with the Paying Agent (or if the Company or an Affiliate
of the Company is acting as the Paying Agent, shall segregate and hold in trust)
cash sufficient to pay the aggregate Purchase Price of the Securities to be
purchased pursuant to this Section 11.02. Payment by the Paying Agent of the
Purchase Price for such Securities shall be made promptly following the later of
the Purchase Date or the time of book-entry transfer or delivery of such
Securities. Subject to Section 12.02 herein and paragraph 6 of the Securities,
no payment or adjustment shall be made for dividends on the Common Stock the
record date for which occurred on or prior to the Purchase Date. If the Paying
Agent holds, in accordance with the terms of this Indenture, cash sufficient to
pay the Purchase Price of such Securities on the Purchase Date, then, on and
after such date, such Securities shall cease to be outstanding and interest
(including any Contingent Interest and Liquidated Damages) on such Securities
shall cease to

                                       64

<PAGE>

accrue, whether or not book-entry transfer of such Securities is made or such
Securities are delivered to the Paying Agent, and all other rights of the Holder
shall terminate (other than the right to receive the Purchase Price and
previously accrued interest (including any Contingent Interest and Liquidated
Damages) upon delivery or transfer of the Securities). Nothing herein shall
preclude any withholding tax required by law.

     (g) The Company shall require each Paying Agent (other than the Trustee) to
agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all cash held by the Paying Agent for the payment of the
Purchase Price and shall notify the Trustee of any default by the Company in
making any such payment. If the Company or an Affiliate of the Company acts as
Paying Agent, it shall segregate the cash held by it as Paying Agent and hold it
as a separate trust fund. The Company at any time may require a Paying Agent to
deliver all cash held by it to the Trustee and to account for any funds
disbursed by the Paying Agent. Upon doing so, the Paying Agent shall have no
further liability for the cash delivered to the Trustee.

     Damages) will cease to accrue on and after the Purchase Date or Fundamental
     Change Purchase Date, as applicable;

          (xi) the CUSIP or ISIN number of the Securities;

     Simultaneously with providing such Company Notice, the Company will publish
a notice containing the information in such Company Notice in a newspaper of

                                       66

<PAGE>

however, that, in all cases, the text of the Company Notice shall be prepared by
the Company.

     (b) Effect of Purchase Notice or Fundamental Change Purchase Notice;
Withdrawal; Effect of Event of Default. Upon receipt by the Company of the

     notice of withdrawal is being submitted;

          (ii) if certificated, the certificate number of the Securities in

     certificated, the written notice of withdrawal must comply with appropriate
     DTC procedures; and

     subject to the original Purchase Notice or Fundamental Change Purchase
     Notice, as the case may be, and which has been or shall be delivered for
     purchase by the Company.

                                       67

<PAGE>

     There shall be no purchase of any Securities pursuant to Section 11.01 or
Section 11.02 or, if an Event of Default has occurred and is continuing (other
than an Event of Default that is cured by the payment of the Purchase Price or
Fundamental Change Purchase Price, as the case may be). The Paying Agent shall
promptly return to the respective Holders thereof any Securities (x) with
respect to which a Purchase Notice or Fundamental Change Purchase Notice, as the
case may be, has been withdrawn in compliance with this Indenture, or (y) held
by it during the continuance of an Event of Default (other than a default that
is cured by the payment of the Purchase Price or Fundamental Change Purchase
Price, as the case may be) in which case, upon such return, the Purchase Notice
or Fundamental Change Purchase Notice with respect thereto shall be deemed to
have been withdrawn.

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

     (d) Covenant to Comply with Securities Laws Upon Purchase of Securities. In
connection with any offer to purchase Securities under Section 11.02 or Section
11.01, the Company shall, to the extent applicable, (a) comply with Rules 13e-4
and 14e-1 (and any successor provisions thereto) under the Exchange Act, if
applicable; (b) file the related Schedule TO (or any successor schedule, form or
report) under the Exchange Act, if applicable; and (c) otherwise comply with all
applicable federal and state securities laws so as to permit the rights and
obligations under Section 11.02 or Section 11.01 to be exercised in the time and
in the manner specified in Section 11.02 or Section 11.01.

     (e) Repayment to the Company. The Trustee and the Paying Agent shall return
to the Company any cash or property that remains unclaimed, as provided in
paragraph 8 of the Securities, together with interest that the Trustee or Paying
Agent, as the case may be, has expressly agreed in writing to pay, if any, that
is held by them for the payment of a Purchase Price or Fundamental Change
Purchase Price, as the case may be; provided, however, that to the extent that
the aggregate amount of cash or property deposited by the Company pursuant to
Section 11.01(c) or Section 11.02(f), as applicable, exceeds the aggregate
Purchase Price or Fundamental Change Purchase Price, as the case may be, of the
Securities or portions thereof which the Company is obligated to purchase as of

                                       68

<PAGE>

the Purchase Date or Fundamental Change Purchase Date, as the case may be, then
promptly on and after the Business Day following the Purchase Date or
Fundamental Change Purchase Date, as the case may be, the Trustee and the Paying
Agent shall return any such excess to the Company together with interest that
the Trustee or Paying Agent, as the case may be, has expressly agreed in writing
to pay, if any.

     (f) Officers' Certificate. At least five Business Days before the Company
Notice Date, the Company shall deliver an Officers' Certificate to the Trustee
specifying whether the Company desires the Trustee to give the Company Notice
required by Section 11.03(a) herein.

                                   ARTICLE 12
                                   CONVERSION

     Section 12.01. Conversion of Securities.

     (a) Right to Convert. Subject to the procedures for conversion set forth in
this Article 12, a Holder may convert its Securities (i) at any time on or after
April 1, 2012 and on or prior to the close of business on the Business Day
immediately preceding Stated Maturity and (ii) prior to April 1, 2012 subject to
the condition and during the periods specified below, in each case at the
Conversion Rate. Whenever the Securities shall become convertible upon one or
more of the conditions stated below, the Company or, at the Company's request,
the Trustee in the name and at the expense of the Company, shall notify the
Holders of the event triggering such convertibility in the manner provided in
Section 14.02, and the Company shall also publicly announce such information by
publication on the Company's website or through such other public medium as it
may use at such time. Any notice so given shall be conclusively presumed to have
been duly given, whether or not the Holder receives such notice.

          (i) Conversion Upon Satisfaction of Sale Price Condition. Prior to
     April 1, 2012, a Holder may surrender all or a portion of its Securities
     for conversion into cash or shares, if any, of Common Stock, during any
     fiscal quarter (and only during such fiscal quarter) commencing after June
     30, 2006, if the Sale Price for the Common Stock for at least 20 Trading
     Days during the period of 30 consecutive Trading Days ending on the last
     Trading Day of the immediately preceding fiscal quarter, is greater than or
     equal to 110% of the applicable Conversion Price in effect on such last
     Trading Day.

          (ii) Conversion Upon Notice of Redemption. If the Company calls any of
     the Securities for redemption, Holders may surrender for conversion into
     cash and shares, if applicable, of Common Stock, such

                                       69

<PAGE>

     Securities called for redemption at any time prior to the close of business
     on the Business Day immediately preceding the related Redemption Date, even
     if the Securities are not otherwise convertible at such time; provided,
     however, if the Holder already has delivered a Purchase Notice with respect
     to a Security, the Holder may not surrender that Security for conversion
     until the Holder has withdrawn the Purchase Notice pursuant to Section
     11.03(b).

          (iii) Conversion Upon Specified Corporate Transactions.

               (A) If the Company (1) distributes to all or substantially all
          holders of Common Stock rights entitling them to purchase shares of
          Common Stock at less than the Sale Price of a share of Common Stock on
          the Trading Day immediately preceding the declaration date of the
          distribution, or (2) distributes to all or substantially all holders
          of Common Stock assets, debt securities or rights to purchase the
          Company's securities of the Company, which distribution has a per
          share Fair Market Value, as determined by the Company's Board of
          Directors, exceeding 5% of the Sale Price of the Common Stock on the
          Trading Day immediately preceding the declaration date for such
          distribution, then, in each case, the Company must notify the Holders,
          in the manner provided in Section 14.02, at least 30 days prior to the
          Ex-Dividend Date for such distribution. Once the Company has given
          such notice, Holders may surrender their Securities for conversion at
          any time until the earlier of the close of business on the Business
          Day immediately prior to such Ex-Dividend Date or the Company's
          announcement that such distribution will not take place. No Holder may
          exercise this right to convert if the Holder otherwise may participate
          in the distribution without conversion.

               (B) If the Company is party to any transaction or event
          (including consolidation, merger or binding share exchange) pursuant
          to which shares of Common Stock would be converted into or exchanged
          for cash, securities or other property, the Company must notify
          Holders, in the manner provided in Section 14.02, at least 30 days
          prior to the anticipated effective date for such transaction. Once the
          Company has given such notice, Holders may surrender Securities for
          conversion at any time from and after the date that is 30 days prior
          to the anticipated effective date of the transaction until 30 calendar
          days after the actual date of such transaction (or, if such
          transaction also constitutes a Change of Control, until the related
          Fundamental Change Purchase Date). The Company will settle any such
          conversions as described under Section 12.01(c). However, if such
          transaction

          also constitutes a Change of Control under which the Conversion Rate
          will be adjusted pursuant to Section 12.03(a), the Company will settle
          any such conversions as described thereunder.

               (C) If a Termination of Trading occurs, Holders may surrender
          Securities for conversion at any time while such Termination of
          Trading is continuing.

A Holder may convert a portion of the principal amount of Securities if the
portion is $1,000 or a multiple of $1,000. The cash payable, and the number of
shares of Common Stock issuable, if any, upon conversion of a Security shall be
determined as set forth in Section 12.01(c).

     (b) Conversion Procedures. The following procedures shall apply to convert
Securities:

          (i) In respect of a Definitive Security, a Holder must (A) complete
     and manually sign the conversion notice attached to the Security, or
     facsimile of such conversion notice; (B) deliver such conversion notice,
     which is irrevocable, and the Security to the Conversion Agent at the
     office maintained by the Conversion Agent for such purpose; (C) to the
     extent any shares of Common Stock issuable upon conversion are to be issued
     in a name other than the Holder's, furnish endorsements and transfer
     documents as may be required by the Conversion Agent and, if required
     pursuant to Section 12.01(e) below, pay all transfer or similar taxes; and
     (D) if required pursuant to Section 2.01(d) above, pay funds equal to
     interest payable on the next interest payment date to which such Holder is
     not entitled.

          (ii) In respect of a beneficial interest in a Global Security, a
     beneficial owner must comply with DTC's procedures for converting a
     beneficial interest in a Global Security and, if required pursuant to
     Section 2.01(d) above, pay funds equal to interest payable on the next
     interest payment date to which such beneficial owner is not entitled.

The date a Holder satisfies the foregoing requirements is the "CONVERSION DATE"
hereunder.

     If a Holder converts more than one Security at the same time, the cash and
number of shares of Common Stock issuable upon the conversion, if any, shall be
based on the total principal amount of the Securities converted.

     Upon surrender of a Security that is converted in part, the Company shall
execute, and the Trustee or the Authenticating Agent shall authenticate and

                                       71

<PAGE>

deliver to the Holder, a new Security in an authorized denomination equal in
principal amount to the unconverted portion of the Security surrendered.

     (c) Payment Upon Conversion. Upon any conversion of any Security, the
Company will deliver to converting Holders, in respect of each $1,000 principal
amount of Securities being converted, a "SETTLEMENT AMOUNT," as follows:

          (i) an amount in cash (the "PRINCIPAL RETURN") equal to the lesser of
     (a) the principal amount of Securities surrendered for conversion and (b)
     the product (the "CONVERSION VALUE") of the Conversion Rate multiplied by
     the Average Price; and

          (ii) if the Conversion Value is greater than the principal amount of
     Securities converted, either (a) a number of shares, for each $1,000
     principal amount of Securities converted, of Common Stock (the "NET
     SHARES"), equal to the sum of the Daily Share Amounts for the related
     Conversion Period or (b) an amount of cash (the "NET CASH") equal to the
     difference between the Conversion Value and the principal amount, at the
     election of the Company by notice to the Trustee and the Holder no later
     than the Business Day prior to the first day of the related Conversion
     Period; provided, however, the Company may at any time irrevocably elect to
     deliver, in lieu of paying Net Cash, Net Shares upon all conversions of the
     Securities following such time. The Company will make any such irrevocable
     election by written notice to the Trustee and the Holders.

     The Conversion Value, Principal Return, Net Cash and the number of Net
Shares, as applicable, will be determined by the Company promptly after the end
of the Conversion Period. The Company shall deliver an Officers' Certificate to
the Trustee setting forth such determination. The Settlement Amount in respect
of any Security converted will be delivered to converting Holders no later than
the third Business Day immediately following the determination of the Average
Price for such Security.

     (d) Cash Payments in Lieu of Fractional Shares. The Company shall not issue
a fractional share of Common Stock upon conversion of Securities. Instead the
Company shall deliver cash for the current market value of the fractional share.
The current market value of a fractional share shall be determined to the
nearest 1/10,000th of a share by multiplying the Average Price of a full share
of Common Stock by the fractional amount and rounding the product to the nearest
whole cent.

     (e) Taxes on Conversion. If a Holder converts Securities, the Company shall
pay any documentary, stamp or similar issue or transfer tax due on the issue

                                       72

<PAGE>

of shares of Common Stock upon the conversion. However, the Holder shall pay any
such tax which is due because the Holder requests the shares to be issued in a
name other than the Holder's name. The Conversion Agent may refuse to deliver
the certificates representing the Common Stock being issued in a name other than
the Holder's name until the Conversion Agent receives a sum sufficient to pay
any tax which shall be due because the shares are to be issued in a name other
than the Holder's name, but the Conversion Agent shall have no duty to determine
if any such tax is due. Nothing herein shall preclude any withholding of tax
required by law.

     (f) Certain Covenants of the Company.

          (i) The Company shall, prior to issuance of any Securities hereunder,
     and from time to time as may be necessary, reserve out of its authorized
     but unissued Common Stock or shares of Common Stock held in treasury,
     sufficient number of shares of Common Stock, free of preemptive rights, to
     permit the conversion of the Securities.

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

          (iii) The Company shall endeavor promptly to comply with all federal
     and state securities laws regulating the issuance and delivery of shares of
     Common Stock upon the conversion of Securities, if any, and shall cause to
     have listed or quoted all such shares of Common Stock on each U.S. national
     securities exchange or over-the-counter or other domestic market on which
     the Common Stock is then listed or quoted.

          (iv) Before taking any action which would cause an adjustment
     increasing the Conversion Rate to an amount that would cause the Conversion
     Price to be reduced below the then par value per share, if any, of the
     shares of Common Stock issuable upon conversion of the Securities, the
     Company will 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.

     Section 12.02. Adjustments to Conversion Rate. The Conversion Rate shall be
adjusted from time to time by the Company as follows:

     (a) If the Company issues shares of Common Stock as a dividend or
distribution on shares of Common Stock, or effects a subdivision or share

                                       73

<PAGE>

combination of the Common Stock, the Conversion Rate will be adjusted based on
the following formula:

                                             OS(1)
                             CR(1) = CR(0) X -----
                                             OS(0)

     where,

      CR(0) = the Conversion Rate in effect at the close of business on the
              Ex-Dividend Date, or the effective date of such share subdivision
              or share combination, as the case may be

      CR(1) = the Conversion Rate in effect immediately after the
              Ex-Dividend Date, or the effective date of such share subdivision
              or share combination, as the case may be

      OS(0) = the number of shares of Common Stock outstanding immediately
              prior to the Ex-Dividend Date, or the effective date of such
              share subdivision or share combination, as the case may be

      OS(1) = the number of shares of Common Stock that would be outstanding
              immediately after such event.

Such adjustment shall become effective immediately after 9:00 a.m., New York
City time, on the Business Day following the Ex-Dividend Date, or effective
date, as the case may be, for such share subdivision or share combination. The
Company will not pay any dividend or make any distribution on shares of Common
Stock held in treasury by the Company. If any dividend or distribution of the
type described in this Section 12.02(a) is declared but not so paid or made, the
Conversion Rate shall again be adjusted to the Conversion Rate that would then
be in effect if such dividend or distribution had not been declared.

     (b) If the Company issues to all or substantially all holders of its Common
Stock any rights or warrants entitling them for a period expiring 45 calendar
days or less from the date of issuance of such rights or warrants to purchase
shares of Common Stock at a price per share less than the Current Market Price
of the Common Stock, the Conversion Rate will be adjusted based on the following
formula (provided that the Conversion Rate will be readjusted to the extent that
such rights or warrants are not exercised prior to their expiration):

                                             OS(0) + X
                             CR(1) = CR(0) X ---------
                                             OS(0) + Y

     where,

                                       74

<PAGE>

      CR(0) = the Conversion Rate in effect immediately prior to the Ex-Dividend
              Date

      CR(1) = the Conversion Rate in effect immediately after the Ex-Dividend
              Date

      OS(0) = the number of shares of Common Stock outstanding immediately prior
              to the Ex-Dividend Date

          X = the total number of shares of Common Stock issuable pursuant to
              such rights

          Y = the number of shares of Common Stock equal to the aggregate price
              payable to exercise such rights divided by the average of the Sale
              Prices of the Common Stock over the 10 consecutive Trading-Day
              period prior to the Business Day immediately preceding the
              announcement of the issuance of such rights.

Such adjustment shall be successively made whenever any such rights or warrants
are issued and shall become effective immediately after 9:00 a.m., New York City
time, on the Business Day following the Ex-Dividend Date. The Company shall not
issue any such rights or warrants in respect of shares of Common Stock held in
treasury by the Company. To the extent that shares of Common Stock are not
delivered after the expiration of such rights or warrants, the Conversion Rate
shall be readjusted to the Conversion Rate that 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 that would then be in effect
if such 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 Sale Price, and in
determining the aggregate offering price of such shares of Common Stock, there
shall be taken into account any consideration received by the Company for such
rights or warrants and any amount payable on exercise or conversion thereof, the
value of such consideration, if other than cash, to be determined by the
Company's Board of Directors.

     (c) If the Company distributes shares of Capital Stock (other than a
distribution consisting solely of Common Stock), evidences of its indebtedness
or other assets of the Company to all or substantially all holders of the Common
Stock, excluding:

                                       75

<PAGE>

          (i) dividends or distributions referred to in clause (a) or (b) above;
     and

          (ii) dividends or distributions paid exclusively in cash;

then the Conversion Rate will be adjusted based on the following formula:

                                              SP(0)
                           CR(1) = CR(0) X -----------
                                           SP(0) - FMV

     where,

      CR(0) = the Conversion Rate in effect immediately prior to the Ex-Dividend
              Date

      CR(1) = the Conversion Rate in effect immediately after the Ex-Dividend
              Date

      SP(0) = the Current Market Price of the Common Stock

        FMV = the fair market value (as determined by the Company's Board of
              Directors) of the shares of Capital Stock, evidences of
              indebtedness, assets or property distributed with respect to each
              outstanding share of Common Stock on the Record Date for such
              distribution.

Such adjustment shall become effective immediately prior to 9:00 a.m., New York
City time, on the Business Day following the Ex-Dividend Date.

With respect to an adjustment pursuant to this clause (c) where there has been a
payment of a dividend or other distribution on the Common Stock of shares of
Capital Stock of any class or series, or similar equity interests in, a
Subsidiary or other business unit (a "SPIN-OFF"), the Conversion Rate in effect
immediately before 5:00 p.m., New York City time, on the effective date for such
Spin-Off will be increased based on the following formula:

                                         FMV(0) + MP(0)
                         CR(1) = CR(0) X --------------
                                              MP(0)

     where,

      CR(0) = the Conversion Rate in effect at the close of business on the
              Ex-Dividend Date

      CR(1) = the Conversion Rate in effect immediately after the Ex-Dividend
              Date

     FMV(0) = the average of the Sale Prices of the Capital Stock or similar
              equity interest distributed to holders of Common Stock applicable
              to one share of Common Stock over the 10 consecutive Trading-Day
              period

                                       76

<PAGE>

              commencing on and including the fifth Trading Day after the
              Ex-Dividend Date

      MP(0) = the average of the Sale Prices of Common Stock over the 10
              consecutive Trading-Day period commencing on and including the
              fifth Trading Day after the Ex-Dividend Date.

Such adjustment shall occur immediately after the final Trading Day of such 10
Trading Day period.

     (d) If any dividend or distribution consisting exclusively of cash is made
to all or substantially all holders of Common Stock, the Conversion Rate will be
adjusted based on the following formula:

                                              SP(0)
                            CR(1) = CR(0) X ---------
                                            SP(0) - C

where,

      CR(0) = the Conversion Rate in effect at the close of business on the
              Ex-Dividend Date

      CR(1) = the Conversion Rate in effect immediately after the Ex-Dividend
              Date

      SP(0) = the Current Market Price of the Common Stock

          C = the amount of cash per share the Company distributes to holders of
              Common Stock

Such adjustment shall become effective immediately after 5:00 p.m., New York
City time, on the Record Date for such dividend or distribution; provided that
if such dividend or distribution is not so paid or made, the Conversion Rate
shall again be adjusted to be the Conversion Rate that would then be in effect
if such dividend or distribution had not been declared.

     (e) If the Company or any of its Subsidiaries makes purchases of Common
Stock pursuant to a tender or exchange offer for Common Stock by the Company or
any of its Subsidiaries, to the extent that the cash and value of any other
consideration included in the payment per share of Common Stock exceeds the Sale
Price of the Common Stock on the Trading Day next succeeding the last date on
which tenders or exchanges may be made pursuant to such tender or exchange offer
(such last date, the "EXPIRATION DATE"), the Conversion Rate will be increased
based on the following formula:

                                       77

<PAGE>

                                          FMV + (SP(1) X OS(1))
                          CR(1) = CR(0) X ---------------------
                                              OS(0) X SP(1)

     where,

      CR(0) = the Conversion Rate in effect on the Expiration Date

      CR(1) = the Conversion Rate in effect immediately after the Expiration
              Date

        FMV = the Fair Market Value (as determined by the Company's Board of
              Directors) of the aggregate value of all cash and any other
              consideration paid or payable for shares validly tendered or
              exchanged and not withdrawn as of the Expiration Date (the
              "PURCHASED SHARES")

      OS(0) = the number of shares of Common Stock outstanding immediately after
              the Expiration Date less any Purchased Shares

      OS(1) = the number of shares of Common Stock outstanding immediately after
              the Expiration Date, including any Purchased Shares

      SP(1) = the Sale Price of Common Stock on the Trading Day next succeeding
              the Expiration Date.

If the Company is obligated to purchase shares pursuant to any such tender or
exchange offer, but the Company is permanently prevented by applicable law from
effecting any such purchases or all such purchases are rescinded, the Conversion
Rate shall again be adjusted to be the Conversion Rate that would then be in
effect if such tender or exchange offer had not been made.

     (f) If a Person other than the Company or any of its Subsidiaries makes a
payment in respect of a tender or exchange offer in which, as of the Expiration
Date, the Company's Board of Directors is not recommending rejection of the
offer, the Conversion Rate will be increased based on the following formula:

                                             FMV + (SP(1) X OS(1))
                             CR(1) = CR(0) X ---------------------
                                                 OS(0) X SP(1)

     where,

      CR(0) = the Conversion Rate in effect on the Expiration Date

      CR(1) = the Conversion Rate in effect immediately after the Expiration
              Date

        FMV = the Fair Market Value (as determined by the Company's Board of
              Directors) of the aggregate consideration payable to the Company's
              shareholders based on the acceptance (up to any maximum specified
              in the terms of the tender or exchange offer) of all shares
              validly

                                       78

<PAGE>

              tendered or exchanged and not withdrawn as of the Expiration Date

      OS(0) = the number of shares of Common Stock outstanding immediately after
              the Expiration Date, including any Purchased Shares

      OS(1) = the number of shares of Common Stock outstanding immediately after
              the Expiration Date less any Purchased Shares

      SP(1) = the Sale Prices of Common Stock on the Trading Day next succeeding
              the Expiration Date

The adjustment referred to in this clause (f) will only be made if:

     (a) the tender offer or exchange offer is for an amount that increases the
     offeror's ownership of Common Stock to more than 25% of the total shares of
     Common Stock outstanding; and

     (b) the cash and value of any other consideration included in the payment
     per share of Common Stock exceeds the Sale Price of the Common Stock on the
     Trading Day next succeeding the last date on which tenders or exchanges may
     be made pursuant to the tender or exchange offer.

     However, the adjustment referred to in this clause (f) will not be made if
as of the closing of the offer, the offering documents disclose a plan or an
intention to cause the Company to engage in a consolidation or merger or a sale
of the consolidated assets of the Company and the Company's Subsidiaries
substantially as an entirety.

     (g) If the application of the foregoing formulas would result in a decrease
to the Conversion Rate, no adjustment to the Conversion Rate will be made.

     (h) Notwithstanding the foregoing provisions of this Section 12.02, no
adjustment shall be made thereunder, nor shall an adjustment be made to the
ability of a Holder of a Security to convert, for any distribution described
therein if the Holder will otherwise participate in the distribution without
conversion of such Holder's Securities.

     (i) The Company may (but is not required to) make such increases in the
Conversion Rate, in addition to those required by clauses (a) through (f) of
this Section 12.02 as the Company's Board of Directors considers to be advisable
to avoid or diminish any income tax to holders of Common Stock resulting from
any dividend or distribution of shares (or rights to acquire shares) or any
similar event treated as such for income tax purposes.

                                       79

<PAGE>

     (j) To the extent permitted by applicable law and subject to applicable
rules of The New York Stock Exchange (if the Common Stock is then listed on The
New York Stock Exchange), the Company from time to time may increase the
Conversion Rate by any amount for any period of at least 20 days if the Board of
Directors shall have made a determination that such increase would be in the
best interests of the Company, which determination shall be conclusive. The
Company shall give at least 15 days' notice of such Conversion Rate increase.

     (k) No adjustment to the Conversion Rate need be made:

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

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

          (iii) upon the issuance of any shares of Common Stock pursuant to any
     option, warrant, right, or exercisable, exchangeable or convertible
     security not described in clause (ii) above and outstanding as of the Issue
     Date;

          (iv) upon the issuance of any shares of Common Stock or any securities
     convertible into or exchangeable for Common Stock or carrying the right to
     purchase any of the foregoing;

          (v) for a change in the par value of the Common Stock; or

          (vi) for accrued and unpaid interest (including any Contingent
     Interest or Liquidated Damages).

To the extent the Securities become convertible into cash, assets or property
(other than capital stock of the Company or securities to which Section 12.03
applies), no adjustment shall be made thereafter as to the cash, assets or
property. Interest shall not accrue on such cash, assets or property.

     (l) If at any time a Conversion Date occurs at a time during which a
Registration Default with respect to the Common Stock (as defined in the
Registration Rights Agreement) has occurred and is continuing, the applicable
Conversion Rate at such time will be increased by 3%.

                                       80

<PAGE>

     (m) All calculations under this Section 12.02 shall be made by the Company
and shall be made to the nearest cent or to the nearest one-ten thousandth
(1/10,000) of a share, as the case may be.

     (n) 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. Unless and until a Trust Officer of the Trustee shall have received
such Officers' Certificate, the Trustee shall not be deemed to have knowledge of
any adjustment of the Conversion Rate and may assume that the last Conversion
Rate of which it has knowledge is still in effect. 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 the Holder of each Security at such Holder's last
address appearing on the Securities Register provided for in Section 2.05 of
this Indenture within 20 days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of any such adjustment.

     (o) Any case in which this Section 12.02 provides that an adjustment shall
become effective immediately after (i) an Ex-dividend Date for an event, (ii)
the date fixed for the determination of a share subdivision or combination
pursuant to Section 12.02(a), or (iii) the Expiration Date for any tender or
exchange offer pursuant to Section 12.02(e), (each a "DETERMINATION DATE"), the
Company may elect to defer until the occurrence of the applicable Adjustment
Event (as hereinafter defined) (x) issuing to the holder of any Security
converted after such Determination Date and before the occurrence of such
Adjustment Event, the additional shares of Common Stock or other securities
issuable upon such conversion by reason of the adjustment required by such
Adjustment Event over and above the Common Stock issuable upon such conversion
before giving effect to such adjustment and (y) paying to such holder any amount
in cash in lieu of any fraction pursuant to Section 12.01. For purposes of this
Section 12.02(n), the term "ADJUSTMENT EVENT" shall mean:

          (iv) in any case referred to in clause (i) hereof, the occurrence of
     such event,

          (v) in any case referred to in clause (ii) hereof, the date any such
     dividend or distribution is paid or made,

          (vi) in any case referred to in clause (iii) hereof, the date a sale
     or exchange of Common Stock pursuant to such tender or exchange offer is
     consummated and becomes irrevocable.

                                       81

<PAGE>

     (p) For purposes of this Section 12.02, 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 will not pay
any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

     (q) Whenever any provision of this Article 12 requires a calculation of an
average of Sale Prices over a span of multiple days, the Company will make
appropriate adjustments (determined in good faith by the Company's Board of
Directors) to account for any adjustment to the Conversion Rate that becomes
effective, or any event requiring an adjustment to the Conversion Rate where the
Ex-Dividend Date of the event occurs, at any time during the period from which
the average is to be calculated.

     (r) Notwithstanding the foregoing, in no event will the total number of
shares of Common Stock issuable upon conversion exceed 57.6037 per $1,000
principal amount of Securities, subject to adjustment in the same manner as the
Conversion Rate pursuant to Section 12.02.

     Section 12.03. Adjustment Upon Certain Fundamental Changes.

     (a) If:

          (i) the Effective Date or anticipated effective date of a transaction
     or event described in clause (2) of the definition of a Change of Control
     occurs on or prior to April 1, 2013, and a Holder elects to convert its
     Securities during the period commencing 30 days prior to such anticipated
     effective date and ending 30 days following the Effective Date, or

          (ii) the Effective Date of a Termination of Trading occurs on or prior
     to April 1, 2013, and a Holder elects to convert its Securities during the
     period commencing on such Effective Date and ending 30 days following such
     Effective Date,

then, in each case, the Conversion Rate for such Securities shall be increased
by an additional number of shares of Common Stock (the "ADDITIONAL SHARES") as
described below. The Company will deliver an Officers' Certificate to the
Trustee setting forth the calculation of Additional Shares to be added to the
Conversion Rate.

     (b) The number of Additional Shares will be determined by reference to the
table attached as Schedule A hereto, based on the actual effective date of such
transaction or event described above (the "EFFECTIVE DATE") and the Stock Price;

                                       82

<PAGE>

provided that if the Stock Price is between two Stock Price amounts set forth in
such table or the Effective Date is between two Effective Dates in the table,
the number of Additional Shares will be determined by a straight-line
interpolation between the number of Additional Shares set forth for the higher
and lower Stock Price amounts and the two dates, as applicable, based on a
365-day year; provided further that if the Stock Price is equal to or in excess
of $60.00 per share (subject to adjustment as set forth in clause (c) below) or
less than $17.36 per share (subject to adjustment as set forth in clause (c)
below), then no Additional Shares will be added to the Conversion Rate.
Notwithstanding the foregoing, in no event will the total number of shares of
Common Stock issuable upon conversion exceed 57.6037 shares per $1,000 principal
amount of Securities, subject to adjustments in the same manner as the
Conversion Rate pursuant to Section 12.02.

     (c) The Stock Prices set forth in the first row of the table in Schedule A
hereto will be adjusted as of any date on which the Conversion Rate of the
Securities is adjusted pursuant to Section 12.02. 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 such adjustment and the denominator of which is the
Conversion Rate as so adjusted. The number of Additional Shares to be added to
the Conversion Rate will be adjusted in the same manner as the Conversion Rate
as set forth in Section 12.02.

     (d) Settlement of Securities tendered for conversion as to which the
Conversion Rate will be increased by Additional Shares pursuant to this Section
12.03 shall occur as follows:

          (i) if the last day of the Conversion Period related to such
     Securities is on or prior to the fourth Trading Day immediately preceding
     the Effective Date, the Company shall deliver the Settlement Amount
     (together with cash in lieu of fractional shares), determined in accordance
     with Section 12.01(c) and Section 12.01(d) above, on the third Business Day
     immediately following the determination of the Average Price; provided that
     such Settlement Amount shall be based on the Conversion Rate without giving
     effect to the Additional Shares to be added thereto as set forth in this
     subsection. As soon as practicable following the Effective Date, the
     Company shall deliver the increase in the Conversion Value for such
     Securities as if the Conversion Rate had been increased by such number of
     Additional Shares during the related Conversion Period (and based upon the
     related Average Price). If such increased Conversion Value results in an
     increase to the Principal Return, the Company shall pay such increase in
     cash. In addition, if such increased Conversion Value results in an
     increase to the number of Net Shares or Net Cash (based on the same
     Conversion Period), the Company will deliver such increase in

                                       83

<PAGE>

     cash or in shares of Common Stock or in the case of Change of Control, in
     Reference Property, as applicable. In no event shall the Company pay any
     such increase to the Settlement Amount if the transaction causing the
     increase to the Conversion Rate pursuant to this subsection never becomes
     effective.

          (ii) If the last day of the Conversion Period for such Securities is
     after the fourth Trading Day immediately preceding the Effective Date, the
     Company shall deliver the Settlement Amount (together with cash in lieu of
     fractional shares) in accordance with Section 12.01(c) and Section 12.01(d)
     above (such determination, for the avoidance of doubt, to include the
     number of Additional Shares to be added to the Conversion Rate as set forth
     in this subsection) on the later to occur of (a) the Effective Date and (b)
     the third Business Day immediately following the last day of the applicable
     Conversion Period.

     Section 12.04. Effect of Reclassification, Consolidation, Merger or Sale.

     (a) If any of the following events occur: (i) any recapitalization,
reclassification or change of the outstanding shares of Common Stock (other than
a subdivision or combination to which Section 12.02(c) applies), (ii) any
consolidation, merger or combination of the Company with another Person as a
result of which holders of Common Stock shall be entitled to receive cash,
securities or other property (or any combination thereof) with respect to or in
exchange for such Common Stock, or (iii) any sale, lease or other transfer of
all or substantially all of the consolidated assets of the Company and its
Subsidiaries, or any statutory share exchange, to any other Person as a result
of which holders of Common Stock shall be entitled to receive cash, securities
or other property or assets (or any combination thereof) with respect to or in
exchange for such Common Stock (any such event or transaction, a "REORGANIZATION
EVENT"), then the Company or the successor or purchasing Person, as the case may
be, shall execute with the Trustee a supplemental indenture (which shall comply
with the Trust Indenture Act as in force at the date of execution of such
supplemental indenture and with the provisions of Article 9 herein) providing
that each Security shall be convertible into the kind and amount of shares or
stock, other securities or other property or assets (including cash or any
combination thereof) that a holder of a number of shares of Common Stock equal
to the applicable Conversion Rate prior to such Reorganization Event would have
owned or been entitled to receive (the "REFERENCE PROPERTY") in such
Reorganization Event. For purposes of the foregoing, the form and amount of
consideration that a holder of Common Stock would have been entitled to receive
in the case of any such Reorganization Event that causes the Common Stock to be
converted into the right to receive more than a single type of consideration
(determined based in part upon any form of stockholder election) will be deemed
to be the weighted average of the forms and amounts of consideration received by
the holders of Common

                                       84

<PAGE>

Stock that affirmatively make such an election. Such supplemental indenture
shall provide for provisions and adjustments which shall be as nearly equivalent
as may be practicable to the provisions and adjustments provided for in this
Article 12, Article 11 and Article 9 and the definition of Fundamental Change,
as appropriate, as determined in good faith by the Company (which determination
shall be conclusive and binding), to make such provisions apply to such other
Person if different from the original issuer of the Securities.

     (b) At and after the effective time of any such Reorganization Event, the
Principal Return of Securities converted shall be payable in cash, and the
Conversion Value, and Net Shares, if any, will be calculated based on the fair
value of the Reference Property.

     (c) Any issuer of securities included in the Reference Property shall
execute an amendment to the Registration Rights Agreement (to the extent any
Registrable Securities (as defined therein) remain outstanding) to make the
provisions thereof applicable to such securities included in the Applicable
Consideration.

     (d) The Company shall cause notice of the execution of any supplemental
indenture required by this Section 12.05 to be mailed to each holder of
Securities, at its address appearing on the Securities Register provided for in
Section 2.05 of this Indenture, within 20 calendar days after execution thereof.
Failure to deliver such notice shall not affect the legality or validity of such
supplemental indenture.

     (e) The above provisions of this Section 12.04 shall similarly apply to
successive Reorganization Events.

     (f) If this Section 12.04 applies to any event or occurrence, Section 12.02
shall not apply in respect of such event or occurrence.

     (g) The Company shall not become a party to any Reorganization Event unless
its terms are consistent with the foregoing. None of the foregoing provisions
shall affect the right of a Holder of Securities to convert the Securities into
cash and shares of Common Stock, if applicable, as set forth in Section 12.01
prior to the effective time of such Reorganization Event.

     Section 12.05. Responsibility of Trustee. The Trustee and any other
Conversion Agent shall not at any time be under any duty or responsibility to
the Company or any Holder of Securities to determine the Conversion Rate, or
whether any facts exist which may require any adjustment of the Conversion Rate,
or with respect to the nature or extent or calculation of any such adjustment
when made, or with respect to the method employed in making the same. The
Trustee and any other Conversion Agent shall not be accountable with respect to

                                       85

<PAGE>

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 Security; and the Trustee and any other Conversion Agent
make no representations with respect thereto. Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Company to issue,
transfer or deliver any cash or shares of Common Stock or stock certificates or
other securities or property upon the surrender of any Security for the purpose
of conversion or to comply with any of the duties, responsibilities or covenants
of the Company contained in this Article 12. Without limiting the generality of
the foregoing, neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any
supplemental indenture entered into pursuant to Section 12.04 relating either to
the kind or amount of shares of stock or securities or property (including cash)
receivable by Holders upon the conversion of their Securities after any
Reorganization Event 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 (which the Company shall be obligated to file with the
Trustee prior to the execution of any such supplemental indenture) with respect
thereto.

     Section 12.06. Notice to Holders Prior to Certain Actions. In case:

     (a) the Company shall declare a dividend (or any other distribution) on its
Common Stock that would require an adjustment in the Conversion Rate pursuant to
Section 12.02; or

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

     (c) of any reclassification or reorganization of the Common Stock of the
Company (other than a subdivision or combination of its 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) of the voluntary or involuntary dissolution, liquidation or winding up
of the Company;

the Company shall cause to be filed with the Trustee and to be mailed to each
Holder of Securities at his address appearing on the Securities Register
provided for in Section 2.05 of this Indenture, as promptly as possible but in
any event at least three (3) calendar days prior to the applicable date
hereinafter specified, a

                                       86

<PAGE>

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 12.07. Stockholder Rights Plan. To the extent that the Company has
a rights plan in effect upon conversion of the Securities into Common Stock, the
Holder will receive, in addition to the Common Stock, the rights under the
rights plan, unless prior to any conversion, the rights have separated from the
Common Stock, in which case the Conversion Rate will be adjusted at the time of
separation as if the Company distributed to all holders of Common Stock shares
of the Company's capital stock, evidences of indebtedness or assets as described
in Section 12.02(c) above, subject to readjustment in the event of the
expiration, termination or redemption of such rights. In lieu of any such
adjustment, the Company may amend such applicable stockholder rights agreement
to provide that upon conversion of the Securities the Holders will receive, in
addition to the Common Stock issuable upon such conversion, the rights which
would have attached to such Common Stock if the rights had not become separated
from the Common Stock under such applicable stockholder rights agreement.

     Section 12.08. Exchange in Lieu of Conversion. (a) When a Holder
surrenders Securities for conversion, the Company may direct the Conversion
Agent to surrender, on or prior to the date of determination of the Average
Price for such Securities, such Securities to a financial institution designated
by the Company (a "FINANCIAL INSTITUTION") for exchange in lieu of conversion.

     (b) In order to accept any such Securities surrendered for conversion, the
Financial Institution must agree to deliver, in exchange for such Securities, a
number of shares of Common Stock equal to the applicable Conversion Rate in
effect at such time, plus cash for any fractional shares, or cash or a
combination of cash and shares of Common Stock in lieu thereof, at the option of
the Financial Institution. Any cash amounts will be based on the Average Price.

     (c) If the Financial Institution accepts any such Securities, it will
deliver the appropriate number of shares of Common Stock or cash, or any
combination thereof, to the Conversion Agent and the Conversion Agent will
deliver those

                                       87

<PAGE>

shares or cash, or combination thereof, as the case may be, to the Holder. Any
Securities exchanged by such Financial Institution will remain outstanding.

     (d) If such Financial Institution agrees to accept any Securities for
exchange but does not timely deliver the related consideration, or if such
Financial Institution does not accept the Security for exchange, the Company
will, as promptly as practical thereafter, but not later than the third Business
Day following the determination of the Average Price, convert the Securities
into cash and shares, if any, of Common Stock, pursuant to Section 12.01(c).

     (e) In no event will the Company's designation of a Financial Institution
pursuant to this Section 12.08 require such Financial Institution to accept any
Securities for exchange. If the Financial Institution declines to accept any
Securities surrendered for exchange, the Company will convert those Securities
into cash and shares, if any, of Common Stock, pursuant to Section 12.01(c). The
Company shall not be obligated to pay any consideration to, or otherwise enter
into any agreement or arrangement with, a Financial Institution for or with
respect to such designation pursuant to this Section 12.08.

                               CONTINGENT INTEREST

     Section 13.01. Contingent Interest. (a) Beginning with the six-month
interest period commencing on April 1, 2013, the Company shall pay interest, in
addition to interest otherwise accruing on the Securities (including any
Liquidated Damages) ("CONTINGENT INTEREST") to the Securityholders for any six
month interest period if the average Trading Price of the Securities for the
five consecutive Trading Day period (the "MEASUREMENT PERIOD") preceding the
first day of the applicable six-month interest period equals 120% or more of the
principal amount of the Securities.

     (b) For any six-month interest period when Contingent Interest is payable,
the Contingent Interest payable on each $1,000 principal amount of Securities
shall equal 0.25% of the average Trading Price for $1,000 principal amount of
the Securities over the Measurement Period triggering the Contingent Interest
payment.

     Section 13.02. Payment of Contingent Interest. Contingent Interest for any
six-month interest period shall accrue from the first day of any interest period
and be paid on the applicable interest payment date to the Person in whose name
any Security is registered on the Securities Register at the corresponding
record date. Contingent Interest due under this Article 13 shall be treated for
all purposes of this Indenture like any other interest accruing on the
Securities.

                                       88

<PAGE>

     Section 13.03. Contingent Interest Notification. By the first Business Day
of any six-month interest period for which Contingent Interest will be paid, the
Company will disseminate a press release through Dow Jones & Company, Inc. or
Bloomberg Business News stating that Contingent Interest will be paid on the
Securities and identifying such six month interest period as the six month
interest period for which such Contingent Interest will be paid. The Company
will deliver a copy of any such press release to the Trustee.

obligations under its Subsidiary Guarantee shall perform such other obligations
as may be imposed upon it with respect to this Indenture under the TIA.

<PAGE>

amount equal to the interest (including any Contingent Interest and Liquidated
Damages) that the Holder is to receive on the Securities. Notwithstanding the
foregoing, no such payment of interest (including any Contingent Interest and
Liquidated Damages) need be made by any converting Holder (i) if the Company has
specified a Redemption Date that is after a Regular Record Date and on or prior
to the corresponding interest payment date, (ii) if the Company has specified a
Fundamental Change Purchase Date during such period, or (iii) to the extent of
any overdue interest (including any Contingent Interest and Liquidated Damages)
existing at the time of conversion of such Security. Except where this Security
is surrendered for conversion and must be accompanied by payment as described
above, no interest, Contingent Interest, if any or Liquidated Damages, if any,
thereon will be payable by the Company on any interest payment date subsequent
to the date of conversion, and delivery of the cash and shares of Common Stock,
if applicable, pursuant to Article 12 of the Indenture, together with any cash
payment for any fractional share, upon conversion will be deemed to satisfy the
Company's obligation to pay the principal amount of the Securities and accrued
and unpaid interest and Contingent Interest, if any or Liquidated Damages, if
any, to, but not including, the related Conversion Date.

2)   Method of Payment

     By no later than 11:00 a.m. (New York City time) on the date on which any
principal of or interest (including any Contingent Interest and Liquidated
Damages), on any Security is due and payable, the Company shall deposit with the
Paying Agent money sufficient to pay such amount. The Company will pay principal
and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of
Securities represented by a Global Security (including principal and interest
(including any Contingent Interest and Liquidated Damages)) will be made by wire
transfer of immediately available funds to the accounts specified by The
Depository Trust Company. The Company will pay principal of Definitive
Securities at the office or agency designated by the Company in the Borough of
Manhattan, The City of New York. Interest (including any Contingent Interest and
Liquidated Damages), on Definitive Securities will be payable (i) to Holders
having an aggregate principal amount of $5,000,000 or less, by check mailed to
the Holders of these Securities and (ii) to Holders having an aggregate
principal amount of more than $5,000,000, either by check mailed to each Holder
or, upon application by a Holder to the Registrar not later than the relevant
record date, by wire transfer in immediately available funds to that Holder's
account within the United States, which application shall remain in effect until
the Holder notifies, in writing, the Registrar to the contrary.

3)   Redemption

                                      A-6

<PAGE>

     No sinking fund is provided for the Securities. Subject to certain
conditions specified in the Indenture, the Securities will be redeemable, at the
option of the Company, in whole at any time or in part from time to time, at any
time on or after April 5, 2013 at a Redemption Price specified in the Indenture.

     In addition, if at any time there is less than $40,000,000 (or if the
Initial Purchasers exercise their over-allotment option, less than 10% of the
aggregate principal amount of Securities originally issued, up to $46,000,000)
aggregate principal amount of Securities outstanding at such time, the Company
may, subject to certain conditions specified in the Indenture, redeem for cash
all the outstanding Securities at the Redemption Price.

4)   Purchase By the Company at the Option of the Holder; Purchase at the Option
     of the Holder Upon a Fundamental Change

     a)   Subject to the terms and conditions of the Indenture, a Holder shall
          have the option to require the Company to purchase all or a portion of
          its Securities held by such Holder on April 1, 2013, April 1, 2016 and
          April 1, 2021 at a Purchase Price specified in the Indenture.

     b)   If a Fundamental Change shall occur at any time, each Holder shall
          have the right, at such Holder's option and subject to the terms and
          conditions of the Indenture, to require the Company to purchase all or
          a portion of its Securities at a Fundamental Change Purchase Price
          specified in the Indenture.

5)   Conversion

     Subject to the conditions and procedures set forth in the Indenture, and
during the periods specified in the Indenture, a Holder may convert Securities,
on or prior to the close of business on the Business Day immediately preceding
Stated Maturity, into cash and shares of Common Stock, if any, at the Conversion
Rate.

     The initial Conversion Rate is 48.0031 shares of Common Stock per $1,000
principal amount of Securities, subject to adjustment in certain events
described in the Indenture. Upon conversion, the Company will pay cash and
shares of Common Stock, if any, based on a Conversion Value and Net Shares or
Net Cash, as applicable, as set forth in the Indenture. The Company shall
deliver cash in lieu of any fractional share of Common Stock.

     A Holder may convert a portion of the Securities only if the principal
amount of such portion is $1,000 or a multiple of $1,000. No payment or
adjustment shall be made for dividends on the Common Stock except as provided in
the Indenture.

                                      A-7

<PAGE>

6)   Denominations; Transfer; Exchange

     The Securities are in registered form without coupons in denominations of
principal amount of $1,000 and whole multiples of $1,000. A Holder may transfer
or exchange Securities in accordance with the Indenture. The Registrar may
require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not register the transfer of or exchange of
Securities (i) for a period of 15 days prior to the mailing of a notice of
redemption of Securities selected for redemption under Article 5 of the
Indenture; (ii) so selected for redemption or, if a portion of any Security is
selected for redemption, the portion thereof selected for redemption; or (iii)
surrendered for conversion or, if a portion of any Security is surrendered for
conversion, the portion thereof surrendered for conversion.

7)   Persons Deemed Owners

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

8)   Unclaimed Money

     If money for the payment of principal or interest (including any Contingent
Interest and Liquidated Damages) remains unclaimed for two years, the Trustee or
Paying Agent shall pay the money back to the Company. After any such payment,
Holders entitled to the money must look only to the Company and not to the
Trustee for payment.

9)   Amendment, Waiver

     The Indenture contains provisions permitting an amendment of the Indenture
or the Securities with the written consent of the Holders of at least a majority
in principal amount of the then outstanding Securities or of at least a majority
in principal amount of Securities then outstanding represented at a
Securityholder meeting at which a quorum is present and the waiver of any Event
of Default (other than with respect to nonpayment or in respect of a provision
that cannot be amended without the written consent of each Securityholder
affected) or noncompliance with any provision with the written consent of the
Holders of a majority in principal amount of the then outstanding Securities or
of at least a majority in principal amount of Securities then outstanding
represented at a Securityholder meeting at which a quorum is present.

     In addition, the Indenture permits an amendment of the Indenture or the
Security without the consent of any Securityholder under circumstances specified
in the Indenture.

                                      A-8

<PAGE>

10)  Defaults and Remedies

     If an Event of Default specified in the Indenture occurs and is continuing,
the Trustee or the Holders of at least 25% in aggregate principal amount of the
Securities may declare all the Securities by notice to the Company to be due and
payable immediately. In addition, certain specified Events of Default will cause
the Securities to become immediately due and payable without further action by
the Holders.

     Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Securityholders notice of any continuing Default or Event of
Default (except a Default or Event of Default in payment of principal or
interest (including any Contingent Interest and Liquidated Damages)) if it
determines that withholding notice is in their interest.

11)  Trustee Dealings with the Company

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

12)  No Recourse Against Others

     An incorporator, director, officer, employee, Affiliate or stockholder, of
each of the Company, or any Subsidiary Guarantor, solely by reason of this
status, shall not have any liability for any obligations of the Company or any
Subsidiary Guarantor under the Securities, the Indenture or any Subsidiary
Guarantee or for any claim based on, in respect of or by reason of such
obligations or their creation. By accepting a Security, each Securityholder
waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

13)  Authentication

     This Security shall not be valid until an authorized signatory of the
Trustee manually authenticates this Security.

15)  CUSIP Numbers

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.
