omission, the action so taken shall not be invalidated or otherwise rendered
ineffective but shall be and remain in full force and effect, except to the
extent that such action was a result of willful misconduct or bad faith. Without
limiting the generality of the foregoing, any Securities or Guarantees issued
under the authority of such defective document or instrument shall nevertheless
be the valid obligations of the Company or the Guarantor, as the case may be,
entitled to the benefits of this Indenture equally and ratably with all other
Outstanding Securities, except as aforesaid.

SECTION 104. ACTS OF HOLDERS.

            (a) Any request, demand, authorization, direction, notice, consent,
election, waiver or other action provided by this Indenture to be made, given or
taken by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing. Except as herein otherwise expressly provided, such action
shall become effective when such instrument or instruments are delivered to the
Trustee and, where it is hereby expressly required, to the Company or the
Guarantor, as applicable. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"ACT" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent, or of the
holding by any Person of a Security, shall be sufficient for any purpose of this
Indenture and (subject to Section 801) conclusive in favor of the Trustee, the
Company and the Guarantor, if made in the manner provided in this Section.

                                       11
<PAGE>
            (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof or may be
proved in any other manner which the Trustee, the Company and the Guarantor deem
sufficient. Where such execution is by a signer acting in a capacity other than
his individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority.

            (c) The ownership, principal amount and register numbers of
Securities held by any Person, and the date of holding the same, shall be proved
by the Security Register.

            (d) Any request, demand, authorization, direction, notice, consent,
election, waiver or other Act of a Holder shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee, the Company or the
Guarantor in reliance thereon, whether or not notation of such action is made
upon such Security.

            (e) Until such time as written instruments shall have been delivered
to the Trustee with respect to the requisite percentage of principal amount of
Securities for the action contemplated by such instruments, any such instrument
executed and delivered by or on behalf of a Holder may be revoked with respect
to any or all of such Securities by written notice by such Holder or any
subsequent Holder, proven in the manner in which such instrument was proven.

            (f) Securities authenticated and delivered after any Act of Holders
may, and shall if required by the Trustee, bear a notation in form approved by
the Trustee as to any action taken by such Act of Holders. If the Company shall
so determine, new Securities, so modified as to conform, in the opinion of the
Trustee and the Company, to such action may be prepared and executed by the
Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities.

            (g) The Company may, at its option, by Company Order, fix in advance
a record date for the determination of Holders entitled to give any request,
demand, authorization, direction, notice, consent, waiver or other Act solicited
by the Company, but the Company shall have no obligation to do so; provided,
however, that the Company may not fix a record date for the giving or making of
any notice, declaration, request or direction referred to in the next sentence.
In addition, the Trustee may, at its option, fix in advance a record date for
the determination of Holders entitled to join in the giving or making of any
Notice of Default, any declaration of acceleration referred to in Section 702,
any request to institute proceedings referred to in Section 707 or any direction
referred to in Section 712. If any such record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other Act, or such
notice, declaration, request or direction, may be given before or after such
record date, but only the Holders of record at the close of business on the
record date shall be deemed to be Holders for the purposes of determining (i)
whether Holders of the requisite proportion of the Outstanding Securities have
authorized or agreed or consented to such Act (and for that purpose the
Outstanding Securities shall be computed as of the record date) and/or (ii)
which Holders

                                       12
<PAGE>
may revoke any such Act (notwithstanding subsection (e) of this Section ); and
any such Act, given as aforesaid, shall be effective whether or not the Holders
which authorized or agreed or consented to such Act remain Holders after such
record date and whether or not the Securities held by such Holders remain
Outstanding after such record date.

SECTION 105. NOTICES, ETC. TO TRUSTEE OR COMPANY.

            Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this

made, given, furnished and filed if personally delivered, on the date of
delivery, if transmitted by facsimile transmission, telex or other direct
written electronic means, on the date of transmission, and if transmitted by
registered mail, on the date of receipt.

SECTION 106. NOTICE TO HOLDERS OF SECURITIES; WAIVER.

            Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of any event, such notice shall be sufficiently
given, and shall be deemed given, to Holders if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at the
address of such Holder as it appears in the Security Register, not later than
the latest date, and not earlier than the earliest date, prescribed for the
giving of such Notice.

            In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice to
Holders by mail, then such notification as shall be made with the approval of
the Trustee shall constitute a sufficient notification for every purpose
hereunder. In any case where notice to Holders is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders.

            Any notice required by this Indenture may be waived in writing by
the Person entitled to receive such notice, either before or after the event
otherwise to be specified therein, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

            If any provision of this Indenture limits, qualifies or conflicts
with another provision hereof which is required or deemed to be included in this
Indenture by, or is otherwise governed by, any provision of the Trust Indenture
Act, such other provision shall control; and if any provision hereof otherwise
conflicts with the Trust Indenture Act, the Trust Indenture Act shall control.
For purposes of this Section, the Indenture shall be deemed to be at all times
qualified under the Trust Indenture Act.

SECTION 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

            The Article and Section headings in this Indenture and the Table of
Contents are for convenience only and shall not affect the construction hereof.

SECTION 109. SUCCESSORS AND ASSIGNS.

            All covenants and agreements in this Indenture by each of the
Company or the Guarantor shall bind its successors and assigns, whether so
expressed or not.

SECTION 110. SEPARABILITY CLAUSE.

                                       14
<PAGE>
            In case any provision in this Indenture or the Securities shall be
held to be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

SECTION 111. BENEFITS OF INDENTURE.

            Nothing in this Indenture or the Securities, express or implied,
shall give to any Person, other than the parties hereto, their successors
hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

SECTION 112. GOVERNING LAW.

            THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

SECTION 113. LEGAL HOLIDAYS.

            In any case where any Interest Payment Date, Redemption Date,
Purchase Date or Fundamental Change Purchase Date or Stated Maturity of any
Security shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture or of the Securities
other than a provision in Securities which specifically states that such
provision shall apply in lieu of this Section) payment of interest or principal
or Additional Amounts need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date,
Redemption Date, Purchase Date or Fundamental Change Purchase Date or Stated
Maturity, and, if such payment is made or duly provided for on such Business
Day, no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Redemption Date, Purchase Date or Fundamental
Change Purchase Date or Stated Maturity, as the case may be, to such Business
Day.

                                  ARTICLE TWO

                                 THE SECURITIES

SECTION 201. TITLE AND TERMS.

            (a) The Securities shall be known and designated as the "2 5/8%
CONVERTIBLE SENIOR NOTES DUE 2023" of the Company. The aggregate principal
amount of Securities which may be authenticated and delivered under this
Indenture is limited to $400,000,000, except for Securities authenticated and
delivered upon registration of transfer of, or in exchange for, or in lieu of
other Securities pursuant to Sections 205, 206, 207, 408, 503, 1102 or 1406. The
Securities shall be issuable in denominations of $1,000 or integral multiples
thereof.

            (b) The Securities shall mature on the date of Stated Maturity.

            (c) Interest on the Securities shall accrue at the rate of 2 5/8%
per annum from and including the Original Issue Date until the principal thereof
is paid or made available for payment. Interest shall be paid semi-annually in
arrears on each Interest Payment Date. In

                                       15
<PAGE>
addition, Additional Amounts may accrue on the Securities and be payable at the
times and in the circumstances described in the Registration Rights Agreement.

            (d) A Holder of any Security at the close of business on a Regular
Record Date shall be entitled to receive interest and Additional Amounts, if
any, on such Security on the corresponding Interest Payment Date. Holders of
Securities at the close of business on a Regular Record Date shall receive
payment of interest payable on the corresponding Interest Payment Date
notwithstanding the conversion of such Securities at any time after the close of
business on such Regular Record Date. Securities surrendered for conversion
during the period from the close of business on any Regular Record Date to the
opening of business on the corresponding Interest Payment Date (except with
respect to Securities in respect of which a Redemption Date or Fundamental
Change Purchase Date has been set that falls within this period or on such
Interest Payment Date or to the extent any overdue interest exists at the time
of such conversion) must be accompanied by payment in funds acceptable to the
Company of an amount equal to the interest that the Holder is to receive on the
Securities. Except where Securities surrendered for conversion must be
accompanied by payment as described above, no interest on converted Securities
will be payable by the Company on any Interest Payment Date subsequent to the
date of conversion.

            (e) Principal of, interest, and Additional Amounts, if any, on
Global Securities shall be payable to DTC in immediately available funds.

            (f) Principal on Definitive Securities shall be payable in
immediately available funds or, at the option of the Company, at the office or
agency of the Company maintained for such purpose, initially the Corporate Trust
Office of the Trustee. Interest and Additional Amounts, if any, on Definitive
Securities shall be payable at the Company's option (A) to Holders having an
aggregate principal amount of Securities of $2,000,000 or less, by check mailed
to the Holders of such Securities at the address therefore set forth in the
Security Register and (B) to Holders having an aggregate principal amount of
Securities of more than $2,000,000, either by check mailed to each such Holder
at the address therefore set forth in the Security Register or, upon application
by any such Holder to the Security Registrar not later than the relevant Regular
Record Date, by wire transfer in immediately available funds to that Holder's
account within the United States specified in such application, which
application shall remain in effect until the Holder notifies, in writing, the
Security Registrar to the contrary.

            (g) The Securities shall be redeemable at the option of the Company
as provided in Article Four.

            (h) The Securities shall be purchasable by the Company at the option
of Holders as provided in Article Five.

            (i) The Securities shall be convertible at the option of the Holders
as provided in Article Eleven.

            (j) The Securities shall be guaranteed as to payment and performance
of conversion rights by the Guarantor as provided in Article Nine; provided that
nothing herein shall require the Guarantee to be endorsed on any Security and
the failure to so endorse a

                                       16
<PAGE>
Guarantee thereon shall not impair the validity or enforceability of the
Guarantee with respect to any such Security.

            (k) The Securities shall initially be issued in the form of one or
more Global Securities.

            (l) The Securities shall be in substantially the form of Exhibit A
hereto with such appropriate insertions, omissions, legends, substitutions and
other variations as are required or permitted by this Indenture, and may have
such letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may be required to comply with the rules of any
securities exchange or as may, consistently herewith, be determined by the
officers executing such Securities, as evidenced by their execution of the
Securities.

SECTION 202. LEGENDS.

            (a) Restricted Securities Legends.

            Each Security issued hereunder shall, upon issuance, bear the legend
set forth in Section 202(a)(1), and each Common Stock certificate representing
shares of the Common Stock issued upon conversion of any Security issued
hereunder, shall, upon issuance, bear the legend set forth in Section 202(a)(2)
(each such legend, a "RESTRICTED SECURITIES LEGEND"), and such legend shall not
be removed except as provided in Section 202(a)(3). Each Security that bears or
is required to bear the Restricted Securities Legend set forth in Section
202(a)(1) (together with each Common Stock certificate representing shares of
the Common Stock issued upon conversion of such Security that bears or is
required to bear the Restricted Securities Legend set forth in Section
202(a)(2), collectively, the "RESTRICTED SECURITIES") shall be subject to the
restrictions on transfer set forth in this Section 202(a) (including the
applicable Restricted Securities Legend set forth below), and the Holder of each
such Restricted Security, by such Holder's acceptance thereof, shall be deemed
to have agreed to be bound by all such restrictions on transfer.

            As used in this Section 202(a), the term "TRANSFER" encompasses any
sale, pledge, transfer or other disposition whatsoever of any Restricted
Security.

      substitution thereof, other than stock certificates representing shares of
      the Common Stock, if any, issued upon conversion thereof which shall bear
      the legend set forth in Section 202(a)(2), if applicable) shall bear a
      Restricted Securities Legend in substantially the following form:

            declared effective under the Securities Act and which continues to
            be effective at the time of such sale) shall bear the applicable
            Restricted Securities Legend set forth in Section 202(a)(1) or
            202(a)(2), as the case may be, until the earlier of:

                        (i)   the date which is the later of two years after the
                  original issuance date of such Security and the last date that
                  the Company, the Guarantor or any of either of their
                  Affiliates was the owner of such Security;

                        (ii)  and the date such Security has, or such shares of
                  the Common Stock have been sold pursuant to a registration
                  statement that has been declared effective under the
                  Securities Act (and which continues to be effective at the
                  time of such sale).

            The Holder must give notice thereof to the Trustee and any transfer
            agent for the Common Stock, as applicable.

                  Notwithstanding the foregoing, the Restricted Securities
            Legend may only 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 and
            the Trustee such satisfactory evidence, which may include an opinion
            of 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, 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 a Common Stock certificate 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 Common

                                       20
<PAGE>
            Stock certificate representing shares of the Common Stock issued
            upon conversion of such Security 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 such restrictions on transfer shall have
            expired in accordance with their terms or as to which the conditions
            for removal of the Restricted Securities Legend set forth in Section
            202(a)(1) as set forth therein have been satisfied may, upon
            surrender of such Security for exchange to the Security Registrar in
            accordance with the provisions of Section 206, 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 202(a)(1).

                  Any Common Stock certificate representing shares of the Common
            Stock issued upon conversion of any Security as to which such
            restrictions on transfer shall have expired in accordance with their
            terms or as to which the conditions for removal of the Restricted
            Securities Legend set forth in Section 202(a)(2) as set forth
            therein 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
            required by Section 202(a)(2).

            (b) 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 DTC, NOMINEES OF DTC OR TO A SUCCESSOR
            THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF THIS GLOBAL
            SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
            RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO ON THE REVERSE
            HEREOF."

SECTION 203. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

            The Securities shall be executed on behalf of the Company by an
Authorized Officer of the Company, and may have the corporate seal of the
Company affixed thereto or reproduced thereon attested by its Secretary, one of
its Assistant Secretaries or any other Authorized Officer. The signature of any
or all of these officers on the Securities may be manual or facsimile.

            A Security bearing the manual or facsimile signature of an
individual who was at the time of execution an Authorized Officer of the Company
shall bind the Company, notwithstanding that any such individual has ceased to
be an Authorized Officer prior to the authentication and delivery of the
Security or did not hold such office at the date of such Security.

            A Security shall not be valid until an authorized officer 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.

            The Trustee shall authenticate and make available for delivery
Securities for issue on the Original Issue Date in an aggregate principal amount
of $400,000,000 upon a Company Order. Such Company Order shall specify the
amount of the Securities to be authenticated and the date on which the issue of
Securities is to be authenticated. The aggregate principal amount of Securities
which may be authenticated and delivered under this Indenture is limited to
$400,000,000 outstanding, except for Securities authenticated and delivered upon
registration or transfer of, or in exchange for, or in lieu of, other Securities
pursuant to Sections 205, 206, 207, 408, 503, 1102 or 1406 hereof.
Notwithstanding anything to the contrary contained in this Indenture, the
Securities will be treated as a single class of securities under this Indenture.
Without limiting the generality of the foregoing sentence, all Securities issued
under this Indenture shall consent together on all matters as one class and no
Securities will have the right to consent as a separate class on any matter.

SECTION 204. FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION.

            The Trustee's certificate of authentication shall be in
substantially the form set forth below:

            This is one of the Securities referred to in the within-mentioned
Indenture.

SECTION 205. TEMPORARY SECURITIES.

            Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued, with such
appropriate insertions, omissions, substitutions and other variations as any
officer executing such Securities may determine, as evidenced by such officer's
execution of such Securities; provided, however, that temporary Securities need
not recite specific redemption, sinking fund, conversion or exchange provisions.

            If temporary Securities are issued, the Company shall cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities, upon surrender of the temporary
Securities at the office or agency of the Company maintained pursuant to Section
302 in a Place of Payment, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor definitive
Securities, of authorized denominations and of like tenor and aggregate
principal amount.

            Until exchanged in full as hereinabove provided, temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of like tenor authenticated and delivered
hereunder.

SECTION 206. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

            The Company shall cause to be kept in one of the offices or agencies
designated pursuant to Section 302, with respect to the Securities, a register
(the "SECURITY REGISTER") in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Securities and
the registration of transfer thereof. The Company shall designate one Person to
maintain the Security Register for the Securities, and such Person is referred
to herein, as the "SECURITY REGISTRAR." The Company hereby designates the
Trustee at its Corporate Trust Office as the initial Security Registrar.
Anything herein to the contrary notwithstanding, the Company may designate one
of its offices or an office of any Affiliate as the office in which the Security
Register with respect to the Securities shall be maintained, and the Company may
designate itself or any Affiliate as the Security Registrar with respect to the
Securities. The Security Register shall be open for inspection by the Trustee
and the Company at all reasonable times.

            Upon surrender for registration of transfer of any Security at the
office or agency of the Company maintained pursuant to Section 302 in a Place of
Payment for such Securities, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the

                                       23
<PAGE>
designated transferee or transferees, one or more new Securities, of authorized
denominations and of like tenor and aggregate principal amount.

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

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

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

            No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 205, 207, 408, 503, 1102 or 1406 not involving any
transfer.

            The Company shall not be required to execute or to provide for the
registration of transfer of or the exchange of (a) Securities, during a period
of 15 days immediately preceding the date notice is to be given identifying the
register numbers of the Securities called for redemption or (b) any Security so
selected for redemption in whole or in part, except the unredeemed portion of
any Security being redeemed in part. In addition, the Security Registrar need
not register the transfer of or exchange any Securities in respect of which a
Purchase Notice or Fundamental Change Purchase Notice has been given and not
withdrawn (except, in the case of a Security to be purchased in part, the
portion of the Security not to be purchased).

SECTION 207. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

            If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

            If there shall be delivered to the Company and the Trustee (a)
evidence to their satisfaction of the ownership of and the destruction, loss or
theft of any Security and (b) such security or indemnity as may be reasonably
required by them to save each of them and the Guarantor and any agent of either
of them harmless, then, in the absence of notice to the Company or the Trustee
that such Security has been acquired by a bona fide purchaser, the Company shall
execute and the Trustee shall authenticate and deliver, in lieu of any such

                                       24
<PAGE>
destroyed, lost or stolen Security, a new Security of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

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

            Upon the issuance of any new Security under this Section 207, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
reasonable expenses (including the fees and expenses of the Trustee) in
connection therewith.

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

            The provisions of this Section 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 208. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

            Unless otherwise provided as contemplated by Section 201 with
respect to the Securities, interest 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 that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

            Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"DEFAULTED INTEREST") shall forthwith cease to be payable to the Holder on the
related Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may 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 date
      (a "SPECIAL RECORD DATE") 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 of the proposed payment, 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

                                       25
<PAGE>
      fix a 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 date
      of the proposed payment 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 promptly cause notice of the proposed
      payment of such Defaulted Interest and the Special Record Date therefor to
      be mailed, first-class postage prepaid, to each Holder of Securities at
      the address of such Holder as it appears in the Security Register, 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
      therefor having been so mailed, such Defaulted Interest shall be paid to
      the Persons in whose names the Securities (or their respective Predecessor
      Securities) are registered at the close of business on such Special Record
      Date.

            (b) The Company may make payment of any Defaulted Interest on the
      Securities in any other lawful manner not inconsistent with the
      requirements of any securities exchange on which such 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 208, 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
accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 209. PERSONS DEEMED OWNERS.

            Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the absolute owner of
such Security for the purpose of receiving payment of principal of and (subject
to Sections 206 and 208) interest, if any, on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and none of the
Company, the Trustee or any agent of the Company, or the Trustee shall be
affected by notice to the contrary.

SECTION 210. BOOK-ENTRY PROVISIONS FOR THE GLOBAL SECURITIES.

            (a) The Global Securities initially shall:

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

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

                  (C) bear the Restricted Securities Legend set forth in Section
            202(a)(1); and

                  (D) bear the Global Security Legend set forth in Section
            202(b).

                                       26
<PAGE>
            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.

            (c) A Global Security may not be transferred, in whole or in part,
to any Person other than the Depositary (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 the Depositary and the provisions of Section 211.

            (d) If at any time:

                  (1) DTC notifies the Company in writing that it is unwilling
            or unable to continue to act as Depositary for the Global Securities
            (including if 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
            notice; or

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

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
Officer's 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 the
Depositary 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 210(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.

            (f) No Obligation of the Trustee.

                                       27
<PAGE>
                  (1) The Trustee shall have no responsibility or obligation to
            any beneficial owner of a Global Security, a member of, or a
            participant in, DTC or other Person with respect to the accuracy of
            the records of DTC or its nominee or of any participant or member
            thereof, with respect to any ownership interest in the Securities or
            with respect to the delivery to any participant, member, beneficial
            owner or other Person (other than DTC) of any notice (including any
            notice of redemption) or the payment of any amount or delivery of
            any Securities (or other security or property) under or with respect
            to such Securities. All notices and communications to be given to
            the Holders and all payments to be made to Holders in respect of the
            Securities shall be given or made only to or upon the order of the
            registered Holders (which shall be DTC or its nominee in the case of
            a Global Security). The rights of beneficial owners in any Global
            Security shall be exercised only through DTC subject to the
            applicable rules and procedures of DTC. The Trustee may rely and
            shall be fully protected in relying upon information furnished by
            DTC with respect to its members, participants and any beneficial
            owners.

                  (2) 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 or among DTC participants, members or
            beneficial owners in 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 211. SPECIAL TRANSFER PROVISIONS.

            Unless a Security is (i) transferred after the time period referred
to in Rule 144(k) under the Securities Act or (ii) sold pursuant to a
registration statement that has been declared effective under the Securities Act
(and which continues to be effective at the time of such sale), the following
provisions shall apply to any sale, pledge or other transfer of 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 Security 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 Security Registrar in

                                       28
<PAGE>
            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
            Security Registrar in writing that:

                  (1) it is purchasing the Securities for its own account or an
            account with respect to which it exercises sole investment
            discretion, in each case for investment and not with a view to
            distribution;

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

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

                  (4) 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

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

            In addition, the Security Registrar shall reflect on its books and
records the date and, if applicable, an increase in the principal amount of the
Global Securities in an amount equal to the aggregate principal amount of the
Definitive Securities to be transferred, and the Trustee shall cancel the
Definitive Securities so transferred.

            (b) Transfer of Securities to an IAI. A form in substantially the
      form below shall be delivered to the Company in connection with any
      transfer of a Definitive Security to an IAI:

                                                                  [Date]

PPL Energy Supply, LLC
PPL Corporation
c/o JPMorgan Chase Bank, as Trustee

Attention: Institutional Trust Services

Dear Sirs:

            This certificate is delivered to request a transfer of $_________
principal amount of the 2 5/8% Convertible Senior Notes due 2023 (the
"Securities") of PPL Energy Supply, LLC (the "Company") fully and
unconditionally guaranteed by and convertible into common stock (the "Common
Stock") of PPL Corporation (the "Guarantor").

            Upon transfer, the Securities would be registered in the name of the
new beneficial owner as follows:

            Name: ___________________________________

                                       29

            Address: ________________________________

            Payment Instructions: _____________________

            Taxpayer ID Number: _____________________

            The undersigned represents and warrants to you that:

            1.    We are an institutional "accredited investor" (as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended
(the "Securities Act")) purchasing for our own account or for the account of
such an institutional "accredited investor" at least $250,000 principal amount
of the Securities, and we are acquiring the Securities not with a view to, or
for offer or sale in connection with, any distribution in violation of the
Securities Act. We have such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risk of our investment in
the Securities and we invest in or purchase securities similar to the Securities
in the normal course of our business. We and any accounts for which we are
acting are each able to bear the economic risk of our or its investment.

            2.    We understand that the Securities and the Common Stock
issuable upon conversion of the Securities have not been registered under the
Securities Act or the securities laws of any state or other jurisdiction and,
unless so registered, may not be sold except as permitted in the following
sentence. We agree on our own behalf and on behalf of any investor account for
which we are purchasing Securities to offer, sell or otherwise transfer such
Securities or Common Stock issuable upon conversion of the Securities prior to
the date that is two years after the later of the date of original issue and the
last date on which the Company or any affiliate of the Company was the owner of
such Securities (or any predecessor thereto) (the "Resale Restriction
Termination Date") only (a) to the Company or the Guarantor, (b) pursuant to a
registration statement which has been declared effective under the Securities
Act, (c) in a transaction complying with the requirements of Rule 144A under the
Securities Act, to a person we reasonably believe is a qualified institutional
buyer as defined Rule 144A (a "QIB") under the Securities Act that purchases for
its own account or for the account of a QIB and to whom notice is given that the
transfer is being made in reliance on Rule 144A, (d) to an institutional
"accredited investor" within the meaning of Rule 501(a)(1), (2), (3) or (7)
under the Securities Act that is purchasing for its own account or for the
account of such an institutional "accredited investor," in each case in a
transaction involving a minimum principal amount of the Securities of $250,000,
for investment purposes and not with a view to or for offer or sale in
connection with any distribution in violation of the Securities Act, or (e)
pursuant to another available exemption from the registration requirements of
the Securities Act, subject to (x) the Company's right prior to any such offer,
sale or transfer pursuant to clauses (d) or (e) to require the delivery of an
opinion of counsel, certification and/or other information satisfactory to it
and (y) in each of the foregoing cases to any requirement of law that the
disposition of our property or the property of such investor account or accounts
be at all times within our or their control and in compliance with any
applicable state securities laws. The foregoing restrictions on resale will not
apply subsequent to the Resale Restriction Termination Date. If any resale or
other transfer of the Securities is proposed to be made pursuant to clause (d)
above prior to the Resale Restriction Termination Date, the transferor shall
deliver a letter from the transferee substantially in the form of this letter to
the Company and the Trustee, which shall provide, among other

                                       30
<PAGE>
things, that the transferee is an institutional "accredited investor" (within
the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and
that it is acquiring such Securities for investment purposes and not for
distribution in violation of the Securities Act.

            TRANSFEREE:______________________

            BY:______________________________

            (c) Other Exchanges.

            In the event that Global Securities are exchanged for Securities in
definitive registered form pursuant to Section 210(d) prior to the effectiveness
of a Shelf Registration Statement with respect to such Securities, such
Securities may be exchanged only in accordance with the provisions of clause (a)
above (including the certification requirements intended to ensure that such
transfers comply with Rule 144A) and such other procedures as may from time to
time be adopted by the Company.

            (d) 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 Security Registrar shall
not register a transfer of any Security unless such transfer complies with the
restrictions on transfer of such Security set forth in this Indenture. The
Security 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 Security 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 Security 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 Security Registrar shall retain copies of all certifications,
letters, notices and other written communications received pursuant to Section
202 hereof or this Section 211. 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 Security
Registrar.

SECTION 212. CANCELLATION.

            All Securities surrendered for payment, redemption, registration of
transfer or exchange or conversion shall, if surrendered to any Person other
than the Trustee, be delivered to

                                       31
<PAGE>
the Trustee and, if not theretofore canceled, shall be promptly canceled by the
Trustee. The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever or which the Company shall not have
issued and sold, and all Securities so delivered shall be promptly canceled by
the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section 212, except as expressly
permitted by this Indenture. All canceled Securities held by the Trustee shall
be disposed of in accordance with the Trustee's customary procedures, and the
Trustee shall promptly deliver a certificate of disposition to the Company
unless, by a Company Order, the Company shall direct that canceled Securities be
returned to it.

SECTION 213. COMPUTATION OF INTEREST.

            Interest on the Securities of each series shall be computed on the
basis of a three hundred sixty (360) day year consisting of twelve (12) thirty
(30) day months, and with respect to any period less than a full calendar month,
on the basis of the actual number of days elapsed during such period.

                                 ARTICLE THREE

                                   COVENANTS

SECTION 301. PAYMENT OF PRINCIPAL AND INTEREST.

            The Company shall pay the principal of, and interest on, the
Securities in accordance with the terms of the Securities and this Indenture.
Whenever in this Indenture there is mentioned, in any context, the payment of
interest on any Security, such mention shall be deemed to include mention of the
payment of Additional Amounts to the extent that, in such context, Additional
Amounts are, were or would be payable in respect thereof pursuant to the
provisions of the Registration Rights Agreement and express mention of the
payment of Additional Amounts (if applicable) in any provisions hereof shall not
be construed as excluding Additional Amounts in those provisions hereof where
such express mention is not made.

SECTION 302. MAINTENANCE OF OFFICE OR AGENCY.

            The Company shall maintain in each Place of Payment for the
Securities, an office or agency where payment of such Securities shall be made
or surrendered for payment, where Securities may be surrendered for conversion,
where registration of transfer or exchange of Securities may be effected and
where notices and demands to or upon the Company in respect of Securities and
this Indenture may be served. The Company shall give prompt written notice to
the Trustee of the location, and any change in the location, of each such office
or agency and prompt notice to the Holders of any such change in the manner
specified in Section 106. If at any time the Company shall fail to maintain any
such required office or agency in respect of Securities or shall fail to furnish
the Trustee with the address thereof, payment of Securities may be made,
Securities may be surrendered for conversion, registration of transfer or
exchange thereof may be effected and notices and demands in respect thereby may
be served at the

                                       32
<PAGE>
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent for all such purposes in any such event.

            The Company may also from time to time designate one or more other
offices or agencies with respect to the Securities for any or all of the
foregoing purposes and may from time to time rescind such designations;
provided, however, that, no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency for such
purposes in each Place of Payment for such Securities in accordance with the
requirements set forth above. The Company shall give prompt written notice to
the Trustee, and prompt notice to the Holders in the manner specified in Section
106, of any such designation or rescission and of any change in the location of
any such other office or agency.

            The Guarantor shall maintain in each Place of Payment for the
Securities, an office or agency where payment of the Guarantees shall be made
and where notices and demands to or upon the Guarantor in respect of the
Guarantees and this Indenture may be served. The Guarantor shall give prompt
written notice to the Trustee of the location, and any change in the location,
of each such office or agency and prompt notice to the Holders of any such
change in the manner specified in Section 106. If at any time the Guarantor
shall fail to maintain any such required office or agency in respect of the
Guarantees or shall fail to furnish the Trustee with the address thereof,
payment of the Guarantees may be made and notices and demands in respect thereby
may be served at the Corporate Trust Office of the Trustee, and the Guarantor
hereby appoints the Trustee as its agent for all such purposes in any such
event.

            The Guarantor may also from time to time designate one or more other
offices or agencies with respect to the Guarantees for any or all of the
foregoing purposes and may from time to time rescind such designations;
provided, however, that, no such designation or rescission shall in any manner
relieve the Guarantor of its obligation to maintain an office or agency for such
purposes in each Place of Payment for the Guarantees in accordance with the
requirements set forth above. The Guarantor shall give prompt written notice to
the Trustee, and prompt notice to the Holders in the manner specified in Section
106, of any such designation or rescission and of any change in the location of
any such other office or agency.

            Anything herein to the contrary notwithstanding, any office or
agency required by this Section 302 may be maintained at an office of the
Company or any Affiliate of the Company, in which event the Company or such
Affiliate, as the case may be, shall perform all functions to be performed at
such office or agency.

            The Company and the Guarantor hereby appoint the Trustee at its
Corporate Trust Office as agent for all the foregoing purposes.

SECTION 303. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

            If the Company shall at any time act as its own Paying Agent with
respect to the Securities, it shall, on or before each due date of the principal
of or interest, if any, on any of such Securities, segregate and hold in trust
for the benefit of the Persons entitled thereto a sum sufficient to pay the
principal or interest so becoming due until such sums shall be paid to such

                                       33
<PAGE>
Persons or otherwise disposed of as herein provided and shall promptly notify
the Trustee of its action or failure so to act.

            Whenever the Company shall have one or more Paying Agents for the
Securities, it shall, prior to each due date of the principal of or interest, if
any, on such Securities, deposit with such Paying Agents sums sufficient
(without duplication) to pay the principal or interest so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such principal or
interest, and (unless such Paying Agent is the Trustee) the Company shall
promptly notify the Trustee of its action or failure so to act.

            The Company shall cause each Paying Agent for the Securities, other
than the Company or the Trustee, to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section 303, that such Paying Agent shall:

            (a) hold all sums held by it for the payment of the principal of, or
      interest, if any, on Securities in trust for the benefit of the Persons
      entitled thereto until such sums shall be paid to such Persons or
      otherwise disposed of as herein provided;

            (b) give the Trustee notice of any default by the Company (or any
      other obligor upon the Securities) in the making of any payment of
      principal of, or interest on, the Securities; and

            (c) at any time during the continuance of any such default, upon the
      written request of the Trustee, forthwith pay to the Trustee all sums so
      held in trust by such Paying Agent.

            The Company may at any time pay, or by Company Order direct any
Paying Agent to pay, to the Trustee all sums held in trust by the Company or
such Paying Agent, such sums to be held by the Trustee upon the same trusts as
those upon which such sums were held by the Company or such Paying Agent and, if
as stated in a Company Order delivered to the Trustee, in accordance with the
provisions of Article Six; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of, or interest,
if any, on any Security and remaining unclaimed for two years after such
principal, or interest has become due and payable shall be paid to the Company
on Company Request, or, if then held by the Company, shall be discharged from
such trust; and, upon such payment or discharge, the Holder of such Security
shall thereafter, as an unsecured general creditor and not as the Holder of an
Outstanding Security, look only to the Company for payment of the amount so due
and payable and remaining unpaid, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; provided, however, that the Trustee
or such Paying Agent, before being required to make any such payment to the
Company, may at the expense of the Company, either (a) cause to be mailed, on
one occasion only, notice to such Holder that such money remains unclaimed and
that, after a

                                       34
<PAGE>
date specified therein, which shall not be less than 30 days from the date of
such mailing, any unclaimed balance of such money then remaining will be paid to
the Company or (b) cause to be published once, in a newspaper published in the
English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, notice that such
money remains unclaimed and that after a date specified therein, which shall not
be less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining will be paid to the Company.

SECTION 304. EXISTENCE AS A LIMITED LIABILITY COMPANY.

            Subject to the rights of the Company under Article Thirteen, the
Company shall do or cause to be done all things necessary to preserve and keep
in full force and effect its corporate existence as a limited liability company;
provided that the Company may convert into a corporation pursuant to the laws of
the jurisdiction of its organization.

SECTION 305. ANNUAL OFFICER'S CERTIFICATE.

            Not later than May 15 in each year, commencing May 15, 2004, the
Company and the Guarantor shall deliver to the Trustee an Officer's Certificate
which need not comply with Section 102, and which need only be executed by its
principal executive officer, principal financial officer or principal accounting
officer, as to such officer's knowledge of such obligor's compliance with all
conditions and covenants under this Indenture, such compliance to be determined
without regard to any period of grace or requirement of notice under this
Indenture.

                                  ARTICLE FOUR

             REDEMPTION OF SECURITIES AT THE OPTION OF THE COMPANY

SECTION 401. REDEMPTION OF SECURITIES AT THE OPTION OF THE COMPANY.

            On or after May 20, 2008, the Securities may be redeemed for cash at
any time as a whole or from time to time in part the option of the Company on
any date (a "REDEMPTION DATE"), at a redemption price equal to 100% of the
principal amount of the Securities to be redeemed plus accrued and unpaid
interest, if any, to, but excluding the Redemption Date (the "REDEMPTION
PRICE"). If the Redemption Date is an Interest Payment Date, interest shall be
paid to the record holder on the relevant Regular Record Date.

SECTION 402. APPLICABILITY OF ARTICLE.

            Redemption of Securities at the election of the Company, as
permitted or required by any provision of this Indenture, shall be made in
accordance with such provision and this Article Four.

SECTION 403. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

            The election of the Company to redeem any Securities pursuant to
Section 401 hereof shall be evidenced by a Board Resolution of the Company. In
case of any redemption at the election of the Company, the Company shall, at
least 45 days prior to the Redemption Date

                                       35
<PAGE>
fixed by the Company (unless a shorter period shall be acceptable 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 404 hereof.

SECTION 404. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

            If less than all the Securities are to be redeemed at any time, 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, on a pro rata basis, by lot or by such other
method as the Trustee shall deem fair and appropriate and which may provide for
the selection for redemption of portions of the principal of the Securities
equal to $1,000 or integral multiples thereof.

            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.

            If any Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed, to
the fullest extent practicable, 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.

            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.

SECTION 405. NOTICE OF REDEMPTION.

            Notice of redemption shall be given in the manner provided for in
Section 106 hereof not less than 30 days 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 15
days prior to the date the notice of redemption is to be given (unless a shorter
period shall be acceptable to the Trustee), an Officer's Certificate requesting
that the Trustee give such notice and setting forth the information to be stated
in such notice as provided in the following items.

            All notices of redemption shall state:

            (a) the Redemption Date,

interest to the Redemption Date), the Conversion Rate and the Conversion Price,

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

            (d) that Holders that want to convert their Securities must satisfy
the requirements set forth in paragraphs 9 and 10 of the reverse of the form of
Securities set forth as Exhibit A hereto,

            (e) 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,

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,

            (g) that on the Redemption Date the Redemption Price (plus accrued
and unpaid interest, if any, to, but excluding the Redemption Date) will become
due and payable upon each such Security, or the portion thereof, to be redeemed,
and, unless the Company defaults in paying the Redemption Price, that interest
on Securities called for redemption (or the portion thereof) will cease to
accrue on and after said date,

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

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

number listed in such notice or printed on the Securities.

SECTION 406. 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 303 hereof) an amount
of money sufficient to pay the Redemption Price of all the Securities which are

therein specified (together with accrued and unpaid interest to the Redemption
Date), and from and after such date (unless the Company shall default in the
payment of the Redemption Price or accrued and unpaid interest to the Redemption
Date) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be
paid by the Company at the Redemption Price (together with accrued and unpaid
interest, if any, to, but excluding the Redemption Date) (subject to the rights
of Holders of record on the relevant Regular Record Date to receive interest due

            If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal, shall, until paid, bear
interest from the Redemption Date at the rate borne by the Securities.

SECTION 408. SECURITIES REDEEMED IN PART

            Any Security which is to be redeemed only in part (pursuant to the
provisions of this Article Four) shall be surrendered at the office or agency of

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 shall authenticate and
make available for delivery to the Holder of such Security at the expense of the

                                  ARTICLE FIVE

                PURCHASE OF SECURITIES AT THE OPTION OF HOLDERS

SECTION 501. PURCHASE OF SECURITIES AT OPTION OF HOLDERS UPON PURCHASE DATES.

            (a) Each Holder of Securities shall have the right to require the
Company to purchase all or any part (equal to $1,000 in principal amount or an
integral multiple thereof) of such Holder's Securities on May 15, 2008, May 15,
2013 and May 15, 2018 (each, a "PURCHASE DATE"), at 100% of the principal amount
thereof (the "PURCHASE PRICE"), plus accrued and unpaid interest, if any, to,
but excluding, such Purchase Date.

            (b) The Company will have the option to pay the Purchase Price for
Securities delivered by Holders for purchase pursuant to this Section 501 by
delivering shares of Common Stock in lieu of cash, subject to the conditions set
forth in Section 501(c) hereof. Upon election to pay the Purchase Price of the
Securities in shares of Common Stock, and the delivery of a Company Purchase
Notice of such election, the Company may not change the form of the Purchase
Price, unless the conditions to deliver shares of Common Stock set forth in
Section 501(c) are not satisfied. In all cases, the Company will pay any accrued
and unpaid interest on the Securities purchased on any Purchase Date in cash.

                                       38
<PAGE>
            In the event that the Company elects to pay the Purchase Price by
delivery of shares of Common Stock pursuant to this Section 501(b), the Company
shall deliver to the Paying Agent on behalf of the Holders a number of shares of
Common Stock equal to the Purchase Price divided by the Market Price of the
shares of Common Stock (as adjusted to take into account any occurrence which
results in an adjustment to the Conversion Price pursuant to Section 1106).
Fractional shares of Common Stock will not be issued upon the purchase by the
Company of a Security; the Company will pay cash based on the then-current
Market Price for all fractional shares.

            (c) The Company shall only have the right to pay the Purchase Price
in connection with any purchase of Securities pursuant to this Section 501 by
delivery of shares of Common Stock if, on the applicable Purchase Date, the
shares of Common Stock to be delivered as payment of the Purchase Price:

                  (1) are registered under the Securities Act and the Exchange
            Act, if required by applicable law; and

                  (2) are qualified or registered as necessary under any
            applicable state or other securities law or are eligible for an
            available exemption therefrom.

            If the foregoing conditions are not satisfied with respect to a
Holder prior to the close of Business on the applicable Purchase Date, the
Company shall pay the Purchase Price of the Securities of such Holder entirely
in cash.

            (d) In connection with any purchase of Securities pursuant to this
Section 501, the Company shall give notice (the "COMPANY PURCHASE NOTICE") to
each Holder of Securities in the manner provided for in Section 106 hereof and
to each beneficial owner of Securities as required by applicable law no fewer
than 20 Business Days prior to any Purchase Date to each Holder of Securities.
The Trustee shall give such notice in the Company's name and at the Company's
expense; provided, however, that the Company shall deliver to the Trustee, not
less than 30 Business Days prior to the applicable Purchase Date, an Officer's
Certificate requesting that the Trustee give the Company Purchase Notice,
setting forth the address of each beneficial owner to whom the notice is to be
sent (which address may be the address of the Depositary) and having attached
thereto the form thereof, which shall set forth, among other things:

                  (1) the Purchase Date, the Purchase Price (and the amount of
            accrued and unpaid interest, if any, to, but excluding, the Purchase
            Date), the Conversion Rate and the Conversion Price;

                  (2) whether the Company elects to pay the Purchase Price of
            the Securities in cash or shares of Common Stock;

                  (3) if the Company elects to pay the Purchase Price in shares
            of Common Stock, the method by which the Market Price is calculated
            and a brief description of the calculation of the number of shares
            of Common Stock to be delivered in payment of the Purchase Price;

<PAGE>
                  (4) that any Securities (or portion thereof) accepted for
            payment (and duly paid on the Purchase Date) shall cease to accrue
            interest on the Purchase Date;

                  (5) that any Securities (or portion thereof) not properly
            submitted will continue to accrue interest;

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

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

            accordance with Article Eleven hereof and paragraph 5 of the reverse
            of the Security only if the applicable Purchase Notice has been
            withdrawn in accordance with the terms of this Indenture;

                  (9) that the Purchase Price for (plus accrued and unpaid
            interest, if any, to, but excluding, the Purchase Date) any Security
            as to which a Purchase Notice has been given and not withdrawn will
            be paid promptly following the later of the Purchase Date and the
            time of surrender of such Security as described in (7);

                  (10) the procedures that Holders must follow in order to
            tender their Securities (or portions thereof) for payment and the
            procedures that Holders must follow in order to withdraw an election
            to tender Securities (or portions thereof) for payment;

                  (11) a brief description of the conversion rights of the
            Securities;

            Securities; and

                  (13) all other instructions and materials necessary to enable
            Holders to submit Securities on the Purchase Date.

            (e) Purchases of Securities under this Section 501 shall be made, at
the option of the Holder thereof, upon:

                  (1) delivery to the Paying Agent by the Holder of a written
            notice of purchase (a "PURCHASE NOTICE") during the period beginning
            at any time from the opening of business on the date that is 20
            Business Days prior to the relevant Purchase Date until the close of
            business on the Purchase Date stating:

                        a. if Definitive Securities have been issued, the
                  certificate number of the Security which the Holder will
                  deliver to be purchased;

                                       40
<PAGE>
                        b. the principal amount of the Security (or portion
                  thereof) which the Holder will deliver to be purchased (which
                  must be in principal amounts of $1,000 or an integral multiple
                  thereof, if less than all of the Securities are being
                  delivered);

                        c. that such Security shall be purchased by the Company
                  as of the Purchase Date pursuant to the terms and conditions
                  specified herein; and

                        d. whether, in the event that the Company elects,
                  pursuant to the Company Purchase Notice, to pay the Purchase
                  Price in shares of Common Stock, but the Purchase Price is
                  ultimately paid to the Holder entirely in cash because any of
                  the conditions to payment of the Purchase Price in shares of
                  Common Stock is not satisfied prior to the close of business
                  on the Purchase Date pursuant to Section 501(c), the Holder
                  elects: (i) to withdraw the Purchase Notice as to some or all
                  of the Securities as to which such Purchase Notice relates
                  (stating the principal amount and certificate numbers, if any,
                  of the Securities as to which such withdrawal shall relate),
                  or (ii) to receive cash in respect of the entire Purchase
                  Price for all Securities or portions of Securities subject to
                  such Purchase Notice; provided that if the Purchase Notice
                  states no such election, the Holder will be deemed to have
                  made the election set forth in clause (ii) above; and

                  (2) delivery of such Security to the Paying Agent prior to, on
            or after the Purchase Date (together with all necessary
            endorsements) at the offices of the Paying Agent, such delivery
            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 501 only if the Security so delivered
            to the Paying Agent shall conform in all material respects to the
            description thereof in the related Purchase Notice, as determined by
            the Company.

            Any purchase by the Company contemplated pursuant to the provisions
of this Section 501 shall be consummated by the delivery of the cash or shares
of Common Stock to be received by the Holder promptly following the later of the
Purchase Date and the time of delivery of the Security.

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

SECTION 502. PURCHASE OF SECURITIES AT THE OPTION OF HOLDERS UPON A FUNDAMENTAL
             CHANGE.

            (a) Upon the occurrence of a Fundamental Change on or prior to the

PURCHASE PRICE") equal to 100% of the principal amount of the Securities to be

                  (3) the Conversion Rate and the Conversion Price;

                  (4) that the Securities which have been tendered for payment
            may be converted if they are otherwise convertible pursuant to

            properly withdrawn in accordance with the terms of this Indenture;

                  (5) that any Security (or portion thereof) accepted for
            payment (and duly paid on the Fundamental Change Purchase Date)
            shall cease to accrue interest on the Fundamental Change Purchase
            Date;

                  (6) that any Securities (or portions thereof) not properly
            tendered will continue to accrue interest;

            order to tender their Securities (or portions thereof) for payment
            and the procedures that Holders of Securities must follow in order
            to withdraw an election to tender Securities (or portions thereof)

            the Fundamental Change Notice stating:

                        a.    if Definitive Securities have been issued, the
                              certificate number of the Security which the
                              Holder will deliver to be purchased;

                        b.    the principal amount of the Security (or portion
                              thereof) which the Holder will deliver to be
                              purchased, which must be in principal amounts of
                              $1,000 or an integral multiple thereof, if less
                              than all of the Securities are being delivered;
                              and

                              specified herein; and

                  (2) delivery of such Security to the Paying Agent prior to, on
            or after the Fundamental Change Purchase Date (together with all

            delivery being a condition to receipt by the Holder of the
            Fundamental Change Payment therefor; provided, however, that such
            Fundamental Change Payment shall be so paid pursuant to this Section
            502 only if the Security so delivered to the Paying Agent shall
            conform in all respects to the description thereof in the related
            Fundamental Change Purchase Notice, as determined by the Company.

            Any purchase by the Company contemplated pursuant to the provisions

SECTION 503. TERMS OF PURCHASE.

            (a) Holders shall be entitled to withdraw their election under

subject to such election or any portion thereof in integral multiples of $1,000,
if the Paying Agent receives not later than one Business Day prior to the
Purchase Date or Fundamental Change Purchase Date, as applicable, a telegram,
telex, facsimile transmission or letter setting forth the name of the Holder,
the principal amount of the Security which was delivered for purchase by the
Holder and a statement that such Holder is withdrawing his election to have all
or portion of such Security purchased.

            (b) On or prior to each Purchase Date or the Fundamental Change
Purchase Date, as applicable, the Company shall irrevocably deposit with the
Trustee or with the Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 303 hereof) an amount
of money, or arrange for the delivery of shares of Common Stock (in the case of
a Purchase Date), to the Trustee or the Paying Agent to be held on behalf of the
Holders, as applicable, sufficient to pay the aggregate Purchase Price or the
Fundamental Change Purchase Price, as applicable, plus an amount of money
sufficient to pay accrued and unpaid interest, if any, payable to the Holders
entitled thereto, to be held for payment in accordance with this Section 503. In

applicable, mail or deliver payment to each tendering Holder of the Purchase
Price or the Fundamental Change Purchase Price, as applicable, of the Securities
of such Holder delivered for purchase. In the event that the aggregate Purchase
Price (plus accrued and unpaid interest, if any, to the Purchase Date or
Fundamental Change Purchase Date, as applicable) delivered by the Company to the
Trustee is less than the amount deposited with the Trustee or the Paying Agent,
the Trustee or the Paying Agent shall deliver the excess to the Company upon
Company Request promptly after the Purchase Date or Fundamental Change Purchase
Date, as applicable.

            (d) Any Security that is tendered only in part (pursuant to the
provisions of this Article Five) shall be surrendered at the office or agency of
the Company maintained for such purpose pursuant to Section 302 hereof (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

                                       44

writing), and the Company shall execute, and the Trustee shall authenticate and
make available for delivery to the Holder of such 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 unpurchased 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.

            (e) The Guarantor and the Company will (i) comply with Rules 13e-4
and 14e-1 (and any successor provisions thereto) under the Exchange Act, if
applicable, (ii) file the related Schedule TO (or any successor schedule, form
or report) under the Exchange Act, if applicable and (iii) otherwise comply with
all applicable federal and state securities laws so as to permit the rights and
obligations under Sections 501, 502 or this Section 503 to be exercised in the
manner specified in Sections 501, 502 or this Section 503. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions relating to the Purchase Date or Fundamental Change Notice, the
Guarantor and the Company shall comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations described
above by virtue thereof.

            This Indenture shall upon Company Request cease to be of further
effect (except as hereinafter expressly provided), and the Trustee, at the
expense of the Company, shall execute such instruments as the Company shall
reasonably request to evidence and acknowledge the satisfaction and discharge of
this Indenture, when:

            (a) no Securities remain Outstanding hereunder; and

            (b) the Company has paid or caused to be paid all other sums payable
      hereunder by the Company.

            Notwithstanding the satisfaction and discharge of this Indenture as
aforesaid, the obligations of the Company and the Trustee under Sections 205,
206, 207, 302, 303, 807 and 814 and this Article shall survive.

            Upon satisfaction and discharge of this Indenture as provided in
this Section 601, the Trustee shall turn over to the Company any and all money,
securities and other property then held by the Trustee for the benefit of the
Holders of the Securities (except for money held pursuant to the last paragraph
of Section 303) and shall execute and deliver to the Company such instruments
as, in the judgment of the Company, shall be necessary, desirable or appropriate
to effect or evidence the satisfaction and discharge of this Indenture.

                          EVENTS OF DEFAULT; REMEDIES

SECTION 701. EVENTS OF DEFAULT.

            "EVENT OF DEFAULT," means any one of the following events:

            (a) the Company defaults in the payment of any interest on any
      Security when it becomes due and payable and continuance of such default
      for a period of 30 days; or

            (b) the Company defaults in the payment of the principal of any
      Security when it becomes due and payable at its Stated Maturity, upon
      redemption or acceleration, or upon the exercise by a Holder of its option
      to require the Company to purchase such Holder's Securities pursuant to
      Section 501 or pursuant to the Company's obligation to purchase Securities
      upon the occurrence of a Fundamental Change pursuant to Section 502; or

            (c) default in the performance of, or breach of, any covenant or
      warranty of the Company or the Guarantor in this Indenture (other than a
      covenant or warranty a default in the performance of which or breach of
      which is elsewhere in this Section 701 specifically dealt with) and
      continuance of such default or breach for a period of 60 days after there
      has been given, by registered or certified mail, to the Company or the
      Guarantor, as applicable, by the Trustee, or to the Company or the
      Guarantor, as applicable, and the Trustee by the Holders of at least 25%
      in principal amount of the Outstanding Securities, a written notice
      specifying such default or breach and requiring it to be remedied and
      stating that such notice is a "NOTICE OF DEFAULT" hereunder, unless the
      Trustee, or the Holders of a principal amount of Securities not less than
      the principal amount of Securities the Holders of which gave such notice,
      as the case may be, shall agree in writing to an extension of such period
      prior to its expiration; provided, however, that the Trustee, or the
      Holders of such principal amount of Securities, as the case may be, shall
      be deemed to have agreed to an extension of such period if corrective
      action is initiated by the Company or the Guarantor within such period and
      is being diligently pursued; or

            (d) a matured event of default, as defined in any of the Company's
      or the Guarantor's instruments under which there may be issued or
      evidenced any debt of the Company that has resulted in the acceleration of
      such debt, in excess of $40,000,000 or any default in payment of debt in
      excess of $40,000,000 at the final maturity (and after the expiration of
      any applicable grace or cure periods); provided that the waiver or cure of
      any default under any such instrument and the rescission and annulment of
      the consequences thereof shall constitute a waiver or cure of the
      corresponding default under this Indenture and a rescission and annulment
      of the corresponding consequences under this Indenture;

            (e) the Company fails to deliver Common Stock upon exercise of the
      conversion right in the Securities;

                                       46

      a decree or order for relief in respect of the Company or the Guarantor in
      an involuntary case or proceeding under any applicable federal or state
      bankruptcy, insolvency, reorganization or other similar law or (2) a
      decree or order adjudging the Company or the Guarantor a bankrupt or
      insolvent, or approving as properly filed a petition by one or more
      Persons other than the Company or the Guarantor seeking reorganization,
      arrangement, adjustment or composition of or in respect of the Company or
      the Guarantor under any applicable federal or state law, or appointing a
      custodian, receiver, liquidator, assignee, trustee, sequestrator or other
      similar official for the Company or the Guarantor or for any substantial
      part of its property, or ordering the winding up or liquidation of its
      affairs, and any such decree or order for relief or any such other decree
      or order shall have remained unstayed and in effect for a period of 60
      consecutive days; or

            (g) the commencement by the Company or the Guarantor of a voluntary
      case or proceeding under any applicable federal or state bankruptcy,
      insolvency, reorganization or other similar law or of any other case or
      proceeding to be adjudicated a bankrupt or insolvent, or the consent by
      the Company or the Guarantor to the entry of a decree or order for relief
      in respect of the Company or the Guarantor in a case or proceeding under
      any applicable federal or state bankruptcy, insolvency, reorganization or
      other similar law or to the commencement of any bankruptcy or insolvency
      case or proceeding against the Company or the Guarantor, or the filing by
      the Company or the Guarantor of a petition or answer or consent seeking
      reorganization or relief under any applicable federal or state law, or the
      consent by the Company or the Guarantor to the filing of such petition or
      to the appointment of or taking possession by a custodian, receiver,
      liquidator, assignee, trustee, sequestrator or similar official of the
      Company or the Guarantor or of any substantial part of its property, or
      the making by the Company or the Guarantor of an assignment for the
      benefit of creditors, or the admission by the Company or the Guarantor in
      writing of its inability to pay its debts generally as they become due, or
      the authorization of such action by the Board of Managers of the Company
      or Board of Directors of the Guarantor.

SECTION 702. ACCELERATION OF STATED MATURITY; RESCISSION AND ANNULMENT.

            If an Event of Default shall have occurred and be continuing, then
in every such case the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Securities may declare the principal amount of all of
the Securities to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders), and upon receipt by the
Company of notice of such declaration such principal amount shall become
immediately due and payable.

            At any time after such a declaration of acceleration with respect to
the Securities shall have been made and before a judgment or decree for payment
of the money due shall have been obtained by the Trustee as hereinafter in this
Article provided, such declaration and its consequences shall, without further
act, be deemed to have been rescinded and annulled, if

            (a) the Company shall have paid or deposited with the Trustee a sum
      sufficient to pay:

                                       47
<PAGE>
                  (1) all overdue interest, if any, on all Outstanding
            Securities;

                  (2) the principal on any Outstanding Securities which have
            become due otherwise than by such declaration of acceleration and
            overdue interest thereon;

                  (3) to the extent that payment of such interest is lawful,
            interest upon overdue interest at the rate borne by the Securities;

                  (4) all amounts due to the Trustee under Section 807;

            and

            (b) all Events of Default with respect to the Securities, other than
      the nonpayment of the principal of Securities which shall have become due
      solely by such declaration of acceleration, shall have been cured or
      waived as provided in Section 713.

No such rescission shall affect any subsequent Event of Default or impair any
right consequent thereon.

SECTION 703. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

            If an Event of Default described in clause (a) or (b) of Section 701
shall have occurred, the Company shall, upon demand of the Trustee, pay to it,
for the benefit of the Holders of the Securities, the whole amount then due and
payable on the Securities for principal and interest, with interest on any
overdue principal and interest, at the rate borne by the Securities, and, in
addition thereto, such further amount as shall be sufficient to cover any
amounts due to the Trustee under Section 807.

            If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon the Securities
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon the
Securities, wherever situated.

            If an Event of Default with respect to the Securities shall have
occurred and be continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.

SECTION 704. TRUSTEE MAY FILE PROOFS OF CLAIM.

            In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such

                                       48
<PAGE>
other obligor or their creditors, the Trustee (irrespective of whether the
principal of the Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Trustee shall
have made any demand on the Company for the payment of overdue principal or
interest) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

            (a) to file and prove a claim for the whole amount of principal and
      interest owing and unpaid in respect of the Securities and to file such
      other papers or documents as may be necessary or advisable in order to
      have the claims of the Trustee (including any claim for amounts due to the
      Trustee under Section 807) and of the Holders allowed in such judicial
      proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amounts due it under Section 807.

            Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, be a member of a creditors' or
similar other committee.

SECTION 705. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

            All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders in respect of which such judgment has been
recovered.

SECTION 706. APPLICATION OF MONEY COLLECTED.

            Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, to the extent permitted by law, at the date or
dates fixed by the Trustee and, in case of the distribution of such money on
account of principal or interest upon presentation of the Securities in respect
of which or for the benefit of which such money shall have been collected and
the notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

            FIRST: To the payment of all amounts due the Trustee under Section
      807;

                                       49
<PAGE>
            SECOND: To the payment of the amounts then due and unpaid upon the
      Securities for principal and interest in respect of which or for the
      benefit of which such money has been collected, ratably, without
      preference or priority of any kind, according to the amounts due and
      payable on the Securities for principal and interest, respectively;

            THIRD: To the payment of the remainder, if any, to the Company or to
      whomsoever may be lawfully entitled to receive the same or as a court of
      competent jurisdiction may direct.

SECTION 707. LIMITATION ON SUITS.

            No Holder shall have any right to institute any proceeding, judicial
or otherwise, with respect to this Indenture, or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless:

            (a) such Holder shall have previously given written notice to the
      Trustee of a continuing Event of Default;

            (b) the Holders of not less than 25% in aggregate principal amount
      of the Outstanding Securities shall have made written request to the
      Trustee to institute proceedings in respect of such Event of Default in
      its own name as Trustee hereunder;

            (c) such Holder or Holders shall have offered to the Trustee
      reasonable indemnity against the costs, expenses and liabilities to be
      incurred in compliance with such request;

            (d) the Trustee for 60 days after its receipt of such notice,
      request and offer of indemnity shall have failed to institute any such
      proceeding; and

            (e) no direction inconsistent with such written request shall have
      been given to the Trustee during such 60-day period by the Holders of a
      majority in aggregate principal amount of the Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

SECTION 708. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND INTEREST.

            Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of, and (subject to Section 208) interest on,
such Security on the Stated Maturity (or, in the case of redemption, on the
Redemption Date or, in the case of purchase, on the Purchase Date or Fundamental
Change Purchase Date, as applicable) and to institute suit for the enforcement
of any such payment, and such rights shall not be impaired without the consent
of such Holder.

SECTION 709. RESTORATION OF RIGHTS AND REMEDIES.

                                       50
<PAGE>
            If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding shall have
been discontinued or abandoned for any reason, or shall have been determined
adversely to the Trustee or to such Holder, then and in every such case, subject
to any determination in such proceeding, the Company, the Guarantor, the Trustee
and such Holder shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
such Holder shall continue as though no such proceeding had been instituted.

SECTION 710. RIGHTS AND REMEDIES CUMULATIVE.

            Except as otherwise provided in the last paragraph of Section 207,
no right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 711. DELAY OR OMISSION NOT WAIVER.

            No delay or omission of the Trustee or of any Holder to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 712. CONTROL BY HOLDERS OF SECURITIES.

            If an Event of Default shall have occurred and be continuing, the
Holders of a majority in principal amount of the Outstanding Securities shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee; provided, however, that

            (a) such direction shall not be in conflict with any rule of law or
      with this Indenture, and

            (b) may not involve the Trustee in personal liability in
      circumstances where indemnity would not, in the Trustee's sole discretion,
      be adequate.

SECTION 713. WAIVER OF PAST DEFAULTS.

            The Holders of not less than a majority in principal amount of the
Outstanding Securities may on behalf of the Holders of all of the Securities
waive any past default hereunder and its consequences, except a default

            (a) in the payment of the principal or interest, or

                                       51
<PAGE>
            (b) in respect of a covenant or provision hereof which under Section
      1402 cannot be modified or amended without the consent of the Holder of
      each Outstanding Security.

            Upon any such waiver, such default shall cease to exist, and any and
all Events of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

SECTION 714. UNDERTAKING FOR COSTS.

            The Company and the Trustee agree, and each Holder by his acceptance
thereof shall be deemed to have agreed, that any court may in its discretion
require, 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, suffered or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant, in each case
in the manner, to the extent, and subject to the exceptions provided in the
Trust Indenture Act; provided, that the provisions of this Section 714 shall not
be deemed to authorize any court to require such an undertaking in and shall not
apply to, any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in aggregate
principal amount of the Outstanding Securities, or to any suit instituted by any
Holder for the enforcement of the payment of the principal of, or interest, if
any, on any Security on or after the Stated Maturity expressed in such Security
(or in the case of redemption, on or after the Redemption Date or, in the case
of purchase, on or after the Purchase Date or Fundamental Change Purchase Date,
as applicable).

SECTION 715. WAIVER OF USURY, STAY OR EXTENSION LAWS.

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

                                  THE TRUSTEE

SECTION 801. CERTAIN DUTIES AND RESPONSIBILITIES.

            (a) Except during the continuance of an Event of Default,

                                       52
<PAGE>
                  (1) 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

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

            (b) In case an Event of Default shall have occurred and be
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

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

                  (1) this subsection shall not be construed to limit the effect
            of subsection (a) of this Section 801;

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

                  (3) the Trustee shall not be liable with respect to any action
            taken or omitted to be taken by it in good faith in accordance with
            the direction of the Holders of a majority in principal amount of
            the Outstanding Securities, as provided herein, relating to the
            time, method and place of conducting any proceeding for any remedy
            available to the Trustee, or exercising any trust or power conferred
            upon the Trustee, under this Indenture; and

                  (4) no provision of this Indenture shall require the Trustee
            to expend or risk its own funds or otherwise incur any 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 for believing that repayment of such funds or
            adequate indemnity against such risk or liability is not reasonably
            assured to it.

            (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

SECTION 802. NOTICE OF DEFAULTS.

                                       53
<PAGE>
            The Trustee shall give notice of any default hereunder to the
Holders of the Securities in the manner and to the extent required to do so by
the Trust Indenture Act, unless such default shall have been cured or waived;
provided, however, that in the case of any default of the character specified in
Section 701(c), no such notice to Holders shall be given until at least 45 days
after the occurrence thereof. For the purpose of this Section 802, the term
"default" means any event which is, or after notice or lapse of time, or both,
would become, an Event of Default with respect to the Securities.

SECTION 803. CERTAIN RIGHTS OF TRUSTEE.

            Subject to the provisions of Section 801 and to the applicable
provisions of the Trust Indenture Act:

            (a) the Trustee may rely and shall be protected in acting or
      refraining from acting upon any resolution, certificate, statement,
      instrument, opinion, report, notice, request, direction, consent, order,
      bond, debenture, note, other evidence of indebtedness or other paper or
      document believed by it to be genuine and to have been signed or presented

      shall deem it desirable that a matter be proved or established prior to
      taking, suffering or omitting any action hereunder, the Trustee (unless
      other evidence be herein specifically prescribed) may, in the absence of
      bad faith on its part, rely upon an Officer's Certificate of the Company
      or the Guarantor;

            (d) the Trustee may consult with counsel and the written advice of
      such counsel or any Opinion of Counsel shall be full and complete
      authorization and protection in respect of any action taken, suffered or
      omitted by it hereunder in good faith and in reliance thereon;

      direction of any Holder pursuant to this Indenture, unless such Holder
      shall have offered to the Trustee security or indemnity reasonably
      satisfactory to the Trustee against the costs, expenses and liabilities
      which might be incurred by it in compliance with such request or
      direction;

            (f) the Trustee shall not be bound to make any investigation into
      the facts or matters stated in any resolution, certificate, statement,
      instrument, opinion, report, notice, request, direction, consent, order,
      bond, debenture, note, other evidence of indebtedness or other paper or

      and, if the Trustee

                                       54
<PAGE>
      shall determine to make such further inquiry or investigation, it shall

for the use or application by the Company or the Guarantor of Securities or the
proceeds thereof.

SECTION 805. MAY HOLD SECURITIES.

            Each of the Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company or the Guarantor, in its
individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 808 and 813, may otherwise deal with the Company or the
Guarantor with the same rights it would have if it were not the Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

SECTION 806. MONEY HELD IN TRUST.

            Money held by the Trustee in trust hereunder need not be segregated

<PAGE>
or investment of any money received by it hereunder except as expressly provided
herein or otherwise agreed with, and for the sole benefit of, the Company.

SECTION 807. COMPENSATION AND REIMBURSEMENT.

            The Company agrees:

            (a) to pay to the Trustee from time to time reasonable compensation
      for all services rendered by it hereunder (which compensation shall not be
      limited by any provision of law in regard to the compensation of a trustee
      of an express trust);

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

            (c) to indemnify the Trustee and hold it harmless from and against,
      any loss, liability or expense reasonably incurred without negligence,
      willful misconduct or bad faith on its part, arising out of or in
      connection with the acceptance or administration of the trust or trusts
      hereunder, including the costs and expenses of defending itself against
      any claim or liability in connection with the exercise or performance of
      any of its powers or duties hereunder.

            As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a lien prior to the Securities upon
all property and funds held or collected by the Trustee as such.

SECTION 808. DISQUALIFICATION; CONFLICTING INTERESTS.

            If the Trustee shall have or acquire any conflicting interest within
the meaning of the Trust Indenture Act, it shall either eliminate such
conflicting interest or resign to the extent, in the manner and with the effect,
and subject to the conditions, provided in the Trust Indenture Act and this
Indenture. To the extent permitted by the Trust Indenture Act, the Trustee shall
not be deemed to have a conflicting interest under Section 310(b)(1) thereof by
virtue of being a trustee under this Indenture and under the following
indentures: the Indenture dated as of November 1, 1997 with PPL Capital Funding,

            There shall at all times be a Trustee hereunder which shall be:

            (a) a corporation organized and doing business under the laws of the
      United States of America, any state thereof or the District of Columbia,
      authorized under such laws to exercise corporate trust powers, having a
      combined capital and surplus of at least

                                       56
<PAGE>
      $50,000,000 and subject to supervision or examination by federal, state or
      District of Columbia authority, or

            (b) if and to the extent permitted by the Commission by rule,
      regulation or order upon application, a corporation or other Person
      organized and doing business under the laws of a foreign government,
      authorized under such laws to exercise corporate trust powers, having a
      combined capital and surplus of at least $50,000,000 or the Dollar
      equivalent of the applicable foreign currency and subject to supervision
      or examination by authority of such foreign government or a political
      subdivision thereof substantially equivalent to supervision or examination
      applicable to United States institutional trustees,

and, in either case, qualified and eligible under this Article Eight and the
Trust Indenture Act. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of such supervising or
examining authority, then for the purposes of this Section 809, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 809 and the Trust Indenture Act, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article Eight.

SECTION 810. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

            (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article Eight shall become effective until
the acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 811.

            (b) The Trustee may resign at any time by giving written notice
thereof to the Company. If the instrument of acceptance by a successor Trustee
required by Section 811 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

            (c) The Trustee may be removed at any time by Act of the Holders of
a majority in principal amount of the Outstanding Securities delivered to the
Trustee and the Company.

            (d) If at any time:

                  (1) the Trustee shall fail to comply with Section 808 after
            written request therefor by the Company or by any Holder who has
            been a bona fide Holder for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 809
            or Section 310(a) of the Trust Indenture Act and shall fail to
            resign after written request therefor by the Company or by any such
            Holder, or

                  (3) the Trustee shall become incapable of acting or shall be
            adjudged a bankrupt or insolvent or a receiver of the Trustee or of
            its property shall be

                                       57
<PAGE>
            appointed or any public officer shall take charge or control of the
            Trustee or of its property or affairs for the purpose of
            rehabilitation, conservation or liquidation,

then, in any such case, (x) the Company by Board Resolution may remove the
Trustee or (y) subject to Section 714, any Holder who has been a bona fide
Holder for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

            (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause
(other than as contemplated by clause (y) in subsection (d) or this Section),
the Company, by Board Resolution, shall promptly appoint a successor Trustee (it
being understood that at any time there shall be only one Trustee) and shall
comply with the applicable requirements of Section 811. If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities shall be appointed
by Act of the Holders of a majority in principal amount of the Outstanding
Securities delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 811, become the successor
Trustee and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 811, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of itself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee.

            (f) The Company shall give notice of each resignation and each
removal of the Trustee or Authenticating Agent and each appointment of a
successor Trustee or Authenticating Agent to all Holders of Securities in the
manner provided in Section 106. Each notice shall include the name of the
successor Trustee or Authenticating Agent and the address of its Corporate Trust
Office.

SECTION 811. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

            (a) In case of the appointment hereunder of a successor Trustee,
every such successor Trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; provided on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of all sums owed to
it, execute and deliver an instrument transferring to such successor Trustee all
the rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

            (b) Upon request of any such successor Trustee, the Company shall
execute any instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in
subsection (a) of this Section.

                                       58
<PAGE>
            (c) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

SECTION 812. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

            Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

SECTION 813. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

            If the Trustee shall be or become a creditor of the Company or any
other obligor upon the Securities (other than by reason of a relationship
described in Section 311(b) of the Trust Indenture Act), the Trustee shall be
subject to any and all applicable provisions of the Trust Indenture Act
regarding the collection of claims against the Company, or such other obligor.
For purposes of Section 311(b) of the Trust Indenture Act (a) the term "cash
transaction" shall have the meaning provided in Rule 11b-4 under the Trust
Indenture Act, and (b) the term "self-liquidating paper" shall have the meaning
provided in Rule 11b-6 under the Trust Indenture Act.

SECTION 814. APPOINTMENT OF AUTHENTICATING AGENT.

            The Trustee may appoint an Authenticating Agent or Agents with
respect to the Securities, which shall be authorized to act on behalf of the
Trustee to authenticate Securities issued upon original issuance, exchange,
registration of transfer or partial redemption thereof or pursuant to Section
207, and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any state or territory thereof
or the District of Columbia or the Commonwealth of Puerto Rico, authorized under
such laws to act as Authenticating Agent, having a combined capital and surplus
of not less than $50,000,000 and subject to supervision or examination by
federal or state authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with

                                       59
<PAGE>
the provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section.

            Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

            An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company. Any successor Authenticating
Agent upon acceptance of its appointment hereunder shall become vested with all
the rights, powers and duties of its predecessor hereunder, with like effect as
if originally named as an Authenticating Agent. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.

            The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

            The provisions of Sections 209, 804 and 805 shall be applicable to
each Authenticating Agent.

            If an Authenticating Agent is appointed pursuant to this Section,
the Securities may have endorsed thereon, in addition to the Trustee's
certificate of authentication, an alternate certificate of authentication in the
following form:

                  This is one of the Securities referred to in the
within-mentioned Indenture:

                                                    JPMorgan Chase Bank,
                                                    as Trustee

                                                    By: _______________________,
                                                    as Authenticating Agent

                                                    By: ________________________
                                                        Authorized Signatory

                                  ARTICLE NINE

                                   GUARANTEE

SECTION 901. GUARANTEE.

            The Guarantor hereby fully, unconditionally and irrevocably
guarantees, as primary obligor and not merely as surety, to each Holder of the
Securities and the Trustee (i) as set forth in Section 1105, the obligations of
the Company to deliver shares of Common Stock pursuant to Sections 501 and 1101
hereof (the "STOCK OBLIGATIONS") and (ii) the full and punctual payment when
due, whether at maturity, by acceleration, by redemption, by purchase or
otherwise, of the principal of, and interest on, the Securities and all other
monetary obligations of the Company under this Indenture (all the foregoing
under this clause (ii) being hereinafter collectively called the "MONETARY
OBLIGATIONS" and, together with the Stock Obligations, the "OBLIGATIONS"). The
Guarantee will be unsecured debt of the Guarantor, not subordinated by its terms
to any other obligations of the Guarantor. The 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 further assent from it, and that it will
remain bound under this Article Nine notwithstanding any extension or renewal of
any Obligation.

            The Guarantor waives presentation to, demand of payment from and
protest to the Company of any of the Monetary Obligations and also waives notice
of protest for nonpayment. The Guarantor waives notice of any default under the
Securities or the Obligations. The obligations of the Guarantor hereunder shall
not be affected by (a) the failure of any Holder or the Trustee 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 Monetary Obligations or any
of them; or (e) any change in the ownership of the Company.

            The Guarantor further agrees that the 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 or the Trustee to any
security held for payment of the Monetary Obligations.

            The obligations of the Guarantor hereunder shall not be subject to
any reduction, limitation, impairment or termination for any reason (other than
payment or performance 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 the Guarantor herein shall not be 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

                                       61
<PAGE>
vary the risk of the Guarantor or would otherwise operate as a discharge of the
Guarantor as a matter of law or equity.

            The Guarantor further agrees that the Guarantee herein shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of principal of, or interest on any of the
Monetary 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 the Guarantor by virtue
hereof, upon the failure of the Company to pay any of the Monetary Obligations
when and as the same shall become due, whether at maturity, by acceleration, by
redemption or otherwise, the 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 Trustee an amount equal to the sum of (i) the unpaid amount of such
Monetary Obligations then due and owing and (ii) accrued and unpaid interest on
such Monetary Obligations then due and owing (but only to the extent not
prohibited by law).

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

            The Guarantor also agrees to pay any and all reasonable costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or the
Holders in enforcing any rights under this Section 901.

SECTION 902. SUBROGATION.

            Notwithstanding any payment or payments made by the Guarantor
hereunder, the Guarantor shall not be entitled to be subrogated to any of the
rights of the Trustee or any Holder against the Company or any collateral
security or guarantee or right of offset held by the Trustee or any Holder for
the payment of the Monetary Obligations, nor shall the Guarantor seek or be
entitled to seek any contribution or reimbursement from the Company in respect
of payments made by the Guarantor hereunder, until all amounts owing to the
Trustee and the Holders, by the Company on account of the Monetary Obligations
are paid in full. If any amount shall be paid to the Guarantor on account of
such subrogation rights at any time when all of the Monetary Obligations shall
not have been paid in full, such amount shall be held by the Guarantor in trust
for the Trustee and the Holders, segregated from other funds of the Guarantor,
and shall, forthwith upon receipt by the Guarantor, be turned over to the
Trustee in the exact form received by the Guarantor (duly indorsed by the
Guarantor to the Trustee, if required), to be applied against the Monetary
Obligations.

SECTION 903. CONSIDERATION.

                                       62

            The Guarantor has received, or will receive, direct or indirect
benefits from the making of the Guarantee.

        CONSOLIDATION, MERGER, CONVEYANCE OR OTHER TRANSFER OF GUARANTOR

SECTION 1001. GUARANTOR MAY CONSOLIDATE, ETC., ONLY ON CERTAIN TERMS.

            The Guarantor shall not consolidate with or merge into any other
Person or convey, transfer or lease its properties and assets substantially as
an entirety to any Person, unless

            (a) the Person formed by such consolidation or into which the
      Guarantor is merged or the Person which acquires by conveyance or
      transfer, or which leases, the properties and assets of the Guarantor,
      substantially as an entirety shall be a corporation organized and existing
      under the laws of the United States, any state thereof or the District of
      Columbia, and shall expressly assume, by an indenture supplemental hereto,
      executed and delivered to the Trustee, in form satisfactory to the
      Trustee, the Guarantee under Sections 901 and 1105 and the performance of
      every obligation of the Guarantor under this Indenture on the part of the
      Guarantor to be performed or observed;

            (b) immediately after giving effect to such transaction, no Event of
      Default with respect to the Guarantor, and no event which, after notice or
      lapse of time or both, would become an Event of Default with respect to
      the Guarantor, shall have occurred and be continuing; and

            (c) the Guarantor shall have delivered to the Trustee an Officer's
      Certificate and an Opinion of Counsel, each stating that such
      consolidation, merger, conveyance or other transfer or lease and such
      indenture supplemental hereto complies with this Article and that all
      conditions precedent herein provided for relating to such transactions
      have been complied with.

SECTION 1002. SUCCESSOR PERSON SUBSTITUTED.

            Upon any consolidation by the Guarantor with or merger by the
Guarantor into any other Person or any conveyance or other transfer or lease of
the properties and assets of the Guarantor substantially as an entirety in
accordance with Section 1001, the successor Person formed by such consolidation
or into which the Guarantor is merged or the Person to which such conveyance, or
other transfer or lease is made shall succeed to, and be substituted for, and
may exercise every right and power of, the Guarantor under this Indenture with
the same effect as if such successor Person had been named as the Guarantor
herein, and thereafter, except in the case of a lease, the predecessor Person
shall be relieved of and released from all obligations under the Guarantee
pursuant to this Indenture, this Indenture and the Securities Outstanding
hereunder (unless the predecessor Person shall have delivered to the Trustee an
instrument waiving such

                                       63
<PAGE>
relief and release), and the Trustee shall acknowledge in writing that the
predecessor Person has been so relieved and released.

SECTION 1003. LIMITATIONS.

            For purposes of clarification and not in limitation of the
provisions of Section 1001, nothing in this Indenture shall be deemed to prevent
or restrict:

            (a) any consolidation or merger after the consummation of which the
      Guarantor would be the surviving or resulting corporation, or

            (b) any conveyance or other transfer, or lease of any part of the
      properties of the Guarantor which does not constitute the entirety, or
      substantially the entirety, thereof, or

            (c) the approval by the Guarantor of, or the consent by the
      Guarantor to, any consolidation or merger of any direct or indirect
      subsidiary or affiliate of the Guarantor, or any conveyance, transfer or
      lease by any such subsidiary or affiliate of any of its assets.

                                 ARTICLE ELEVEN

                            CONVERSION OF SECURITIES

SECTION 1101. CONVERSION PRIVILEGE.

            Subject to and upon compliance with the provisions of this
Indenture, a Holder of a Security may convert such Security into shares of
Common Stock, at any time prior to close of business on the date of Stated
Maturity, in accordance with the terms of this Article Eleven and only in the
circumstances set forth in the fifth paragraph on the reverse of the Securities.
The Company shall notify the Trustee (which shall in turn notify the Holders
promptly upon receipt of such notification from the Company) of any date on
which the Securities become convertible (and, if the Securities cease to be
convertible at any time or from time to time, of the first date thereafter on
which the Securities again become convertible), which notification shall set
forth the calculations on which such determination was made.

            The rate at which shares of Common Stock shall be delivered upon
conversion (the "CONVERSION RATE") shall be initially 20.1106 shares of Common
Stock for each $1,000 principal amount of Securities. The Conversion Rate shall
be adjusted in certain circumstances as provided in this Article Eleven. The
price at which shares of Common Stock shall be issued and delivered upon
conversion (the "CONVERSION PRICE") shall at any time be equal to $1,000 divided
by the then applicable Conversion Rate (and rounded to the nearest cent).

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

SECTION 1102. CONVERSION PROCEDURE.

                                       64
<PAGE>
            To convert a Security, a Holder must satisfy the requirements in the
ninth paragraph on the reverse of the Securities. The first Business Day on
which the Holder satisfies all those requirements and submits such Holder's
Securities for conversion is hereinafter referred to as the "CONVERSION DATE."

            As soon as practicable after the Conversion Date, the Company shall
deliver to the Holder, through the transfer agent for the shares of Common
Stock, a certificate for, or a beneficial interest in a global certificate
representing, the number of shares of Common Stock issuable upon the conversion
or exchange and cash in lieu of any fractional share determined pursuant to
Section 1103. The Company shall take all necessary actions to ensure that the
Person in whose name the certificate is registered is entered into the
Guarantor's share register as a shareholder of record as of the close of
business on the Conversion Date, or as soon thereafter as is possible. Upon
conversion by a Holder of a Security in its entirety, such person shall no
longer be a Holder of such Security.

            No payment or adjustment will be made for dividends on, or other
distributions with respect to, any shares of Common Stock except as provided in
this Article Eleven. Upon conversion of a Security, except as provided in
Section 201(d) with respect to interest payable on Securities or portions
thereof converted after a Regular Record Date, that portion of accrued and
unpaid interest on the converted Securities attributable to the period from the
most recent Interest Payment Date through the Conversion Date shall not be
cancelled, extinguished or forfeited, but rather shall be deemed to be paid in
full to the Holder thereof through delivery of the shares of Common Stock
(together with the cash payment, if any, in lieu of fractional shares) for the
Security being converted pursuant to the provisions hereof. The Company will not
adjust the Conversion Rate to account for accrued interest, if any. If the
Holder converts more than one Security at the same time, the number of shares of
Common Stock issuable upon the conversion shall be based on the total principal
amount of the Securities converted.

            In the event that a Holder elects to convert all or any portion of a
Security into shares of Common Stock as set forth in Section 1101, the Company
may elect to pay an amount in cash per Security equal to the product of the (x)
the Applicable Stock Price and (y) the Conversion Rate in effect on the
Conversion Date to satisfy all of its conversion obligation if the Company
notifies such Holder through the Trustee its election to satisfy its conversion
obligation by payment of cash at any time on or before the date that is two
Business Days following the Conversion Date (such period, the "CASH SETTLEMENT
NOTICE PERIOD"). If the Company timely elects to pay cash for the shares of
Common Stock otherwise issuable to the Holder, the Holder may retract the
Conversion Notice at any time during the two Business Day period beginning on
the day after the final day of the Cash Settlement Notice Period. No such
retraction may be made (and a conversion notice shall be irrevocable) if the
Company does not elect to deliver cash in lieu of shares (other than cash in
lieu of fractional shares). If the conversion notice has not been retracted,
then settlement (in cash) will occur within 10 Business Days following the
applicable Conversion Date. The Company shall notify the Trustee and the
Conversion Agent of the amount of cash payable for each $1,000 principal amount
of the Securities in accordance with this paragraph promptly after the
determination thereof. If an Event of Default (except a default in payment of
cash upon conversion of the Securities) shall have occurred and be continuing,
the Company may not pay cash to Holders of Securities under this Section 1102
(except as provided under Section 1103).

                                       65
<PAGE>
            If the last day on which a Security may be converted is not a
Business Day, the Security may be surrendered on the next succeeding day that is
a Business Day.

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

SECTION 1103. FRACTIONAL SHARES.

            The Company will not deliver fractional shares of Common Stock upon
conversion of a Security. Instead, the Company will pay cash based on the
then-current market value for all fractional shares on the New York Stock
Exchange or other principal United States securities exchange upon which the
shares of Common Stock are then listed or, if not so listed, on the Nasdaq
National Market. The current market value of a fractional share of Common Stock
shall be determined, to the nearest 1/1,000th of a share, by multiplying the
Sale Price on the last trading day immediately prior to the Conversion Date, of
a full share by the fractional amount and rounding the product to the nearest
whole cent. In the event that a Holder elects to have more than one Security
converted, the number of shares of Common Stock shall be based on the aggregate
principal amount of Securities to be converted.

SECTION 1104. TAXES ON CONVERSION.

            If a Holder submits a Security for conversion, the Company shall pay
all documentary, transfer or stamp taxes or duties and all other taxes or
duties, if any, which may be imposed by the United States or any political
subdivision thereof or taxing authority thereof or therein with respect to the
issuance of shares of Common Stock upon the conversion. However, the Holder
shall pay any such tax which is due because the Holder requests the shares to be
issued in a name other than the Holder's name. The Conversion Agent may refuse
to deliver the certificates representing the shares of Common Stock being issued
in a name other than the Holder's name until the Conversion Agent receives a sum
sufficient to pay any tax which will be due because the shares of Common Stock
are to be issued in a name other than the Holder's name. Nothing herein shall
preclude any tax withholding required by law or regulations.

SECTION 1105. GUARANTOR TO PROVIDE SHARES OF COMMON STOCK.

            The Guarantor shall, prior to delivery by the Company of shares of
Common Stock under this Article Eleven or Section 501, and from time to time as
may be necessary, reserve out of its authorized but unissued shares of Common
Stock a sufficient number of shares of Common Stock to permit the conversion or
purchase of the Securities in accordance with their terms.

            The Guarantor hereby fully, unconditionally and irrevocably
guarantees the obligations of the Company to deliver the shares of Common Stock
pursuant to Sections 501 and 1101 to each Holder of the Securities and the
Trustee. Any Holder of the Securities and the Trustee shall have the right to
proceed directly against the Guarantor without first proceeding against the
Company to enforce the Company's rights under Sections 501 and 1101 to receive
shares of Common Stock or to obtain delivery of any shares of Common Stock owed
to the Holders of the Securities upon purchase or conversion of the Securities.

                                       66
<PAGE>
            All shares of Common Stock issued and delivered upon conversion by
the Company of the Securities shall be newly issued 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. The Company and the
Guarantor will endeavor promptly to comply with all U.S. federal and state
securities laws regulating the offer and the issuance and delivery of shares of
Common Stock upon conversion of Securities, if any, and will list or cause to
have quoted such shares of Common Stock on each national securities exchange or
in the over-the-counter market or such other market on which the shares of
Common Stock are then listed or quoted.

SECTION 1106. ADJUSTMENT OF CONVERSION RATE.

            (a) Adjustments for Dividends, Distributions, Stock Splits, Etc.

                  (1) In case the Guarantor shall pay or make a dividend or
            other distribution on the Common Stock in Common Stock, the
            Conversion Rate, as in effect at the opening of business on the day
            following the date fixed for the determination of stockholders
            entitled to receive such dividend or other distribution, shall be
            increased by dividing such Conversion Rate by a fraction of which
            the numerator shall be the number of shares of Common Stock
            outstanding at the close of business on the date fixed for such
            determination and the denominator shall be the sum of such number of
            shares and the total number of shares constituting such dividend or
            other distribution, such increase to become effective immediately
            after the opening of business on the day following the date fixed
            for such determination. For the purposes of this Section 1106(a)(1),
            the number of shares of Common Stock at any time outstanding shall
            not include shares held in treasury by the Guarantor but shall
            include any shares issuable in respect of any scrip certificates
            issued in lieu of fractions of shares of Common Stock. The Guarantor
            will not pay any dividend or make any distribution on shares of
            Common Stock held in treasury by the Guarantor.

                  (2) In case the Guarantor shall issue rights, warrants or
            options (other than pursuant to a dividend reinvestment plan or
            share purchase plan) to all holders of its Common Stock entitling
            them, for a period expiring within 45 days after the date of
            issuance of such rights, warrants or options, to subscribe for or
            purchase shares of Common Stock at a price per share less than the
            Current Market Price per share of the Common Stock on such date of
            issuance, the Conversion Rate in effect at the opening of business
            on such date of issuance shall be increased by dividing such
            Conversion Rate by a fraction of which the numerator shall be the
            number of shares of Common Stock outstanding at the close of
            business on such date of issuance plus the number of shares of
            Common Stock which the aggregate offering price of the total number
            of shares of Common Stock so offered for subscription or purchase
            would purchase at such Current Market Price and the denominator
            shall be the number of shares of Common Stock outstanding at the
            close of business on such date of issuance plus the number of shares
            of Common Stock so offered for subscription or purchase, such
            increase to become effective immediately after the opening of
            business on the day following such date of issuance. For the
            purposes of this Section 1106(a)(2), the number of shares of

                                       67
<PAGE>
            Common Stock at any time outstanding shall not include shares held
            in treasury by the Guarantor but shall include any shares issuable
            in respect of any scrip certificates issued in lieu of fractions of
            shares of Common Stock. The Guarantor shall not issue any such
            rights, options or warrants in respect of shares of Common Stock
            held in treasury by the Guarantor.

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

                  (4) In case the Guarantor shall, by dividend or otherwise,
            distribute to all holders of its Common Stock evidences of
            indebtedness of the Guarantor or any of its subsidiaries, shares of
            capital stock, securities, cash, property or other assets (but
            excluding any rights, options or warrants referred to in Section
            1106(a)(2), any dividend or distribution paid exclusively in cash
            and any dividend or distribution referred to in Section 1106(a)(1)),
            the Conversion Rate shall be adjusted by dividing the Conversion
            Rate in effect immediately prior to the close of business on the
            date fixed for the determination of stockholders entitled to receive
            such distribution by a fraction of which the numerator shall be the
            Current Market Price per share of the Common Stock on the date fixed
            for such determination less the then fair market value (as
            determined by the Board of Directors, whose determination shall be
            conclusive and described in a Board Resolution) on such date of the
            portion of the evidences of indebtedness, shares of capital stock,
            securities, cash or other property so distributed applicable to one
            share of Common Stock and the denominator shall be such Current
            Market Price per share of the Common Stock, such adjustment to
            become effective immediately prior to the opening of business on the
            day following the date fixed for the determination of stockholders
            entitled to receive such distribution; provided, however, that in
            the event that the distribution referred to in this Section
            1006(a)(4) consists of capital stock of, or similar equity interests
            in, a Subsidiary or other business unit of the Guarantor, the
            Conversion Rate shall be adjusted by dividing the Conversion Rate in
            effect immediately prior to the close of business on the date fixed
            for the determination of stockholders entitled to receive such
            distribution by a fraction of which the numerator shall be the
            Spin-off Market Price per share of the Common Stock on the date
            fixed for such determination less the Spin-off Market Price per
            share or similar equity interest of the Subsidiary or other business
            unit of the Guarantor on such date and the denominator shall be the
            Spin-off Market Price per share of the Common Stock, such adjustment
            to become effective 10 trading days after the effective date of such
            distribution of

                                       68
<PAGE>
            capital stock of, or similar equity interest in, a Subsidiary or
            other business unit of the Guarantor. In any case in which this
            Section 1106(a)(4) is applicable, Sections 1106(a)(1) and 1106(a)(2)
            shall not be applicable.

                  (5) In case the Guarantor shall, by dividend or otherwise,
            distribute to all holders of its Common Stock cash (excluding (x)
            any quarterly cash dividend on the Common Stock to the extent the
            aggregate cash dividend per share of Common Stock in any fiscal
            quarter does not exceed the greater of (A) the amount per share of
            Common Stock of the next preceding quarterly cash dividend on the
            Common Stock to the extent that such preceding quarterly dividend
            did not require any adjustment of the Conversion Rate pursuant to
            this Section 1106(a)(5) (as adjusted to reflect subdivisions, splits
            or combinations of the Common Stock), and (B) 1.25% of the
            arithmetic average of the Closing Sale Price during the ten Trading
            Days immediately prior to the date of declaration of such dividend,
            and (y) any dividend or distribution in connection with the
            liquidation, dissolution or winding up of the Guarantor, whether
            voluntary or involuntary), then, in such case, the Conversion Rate
            shall be increased so that the same shall equal the rate determined
            by multiplying the Conversion Rate in effect immediately prior to
            the close of business on such record date by a fraction, (i) the
            numerator of which shall be the Current Market Price on such record
            date; and (ii) the denominator of which shall be the Current Market
            Price on such record date less the amount of cash so distributed
            (less any portion of a quarterly cash dividend permitted to be
            excluded pursuant to clause (x) above) applicable to one share of
            Common Stock, such adjustment to be effective immediately prior to
            the opening of business on the day following the record date;
            provided that if the portion of the cash so distributed applicable
            to one share of Common Stock is equal to or greater than the Current
            Market Price on the record date, in lieu of the foregoing
            adjustment, adequate provision shall be made so that each Holder
            shall have the right to receive upon conversion the amount of cash
            such Holder would have received had such Holder converted each
            Security on the record date. If such dividend or distribution is not
            so paid or made, the Conversion Rate shall again be adjusted to be
            the Conversion Rate that would then be in effect if such dividend or
            distribution had not been declared.

                  (6) In case a tender or exchange offer made by the Guarantor
            or any Subsidiary of the Guarantor for all or any portion of the
            Common Stock shall expire and such tender or exchange offer (as
            amended upon the expiration thereof) shall require the payment to
            stockholders (based on the acceptance (up to any maximum specified
            in the terms of the tender or exchange offer) of Purchased Shares
            (as defined below)) of an aggregate consideration having a fair
            market value (as determined by the Board of Directors, whose
            determination shall be conclusive and described in a Board
            Resolution) that as of the last time (the "EXPIRATION TIME") tenders
            or exchanges may be made pursuant to such tender or exchange offer
            (as it may be amended) exceeds the Closing Sale Price of a share of
            Common Stock on the Trading Day next succeeding the Expiration Time,
            the Conversion Rate shall be adjusted so that the same shall equal
            the rate determined by dividing the Conversion Rate in effect
            immediately prior to the

                                       69
<PAGE>
            Expiration Time by a fraction (i) the numerator of which shall be
            equal to (A) the product of (I) the Current Market Price per share
            of the Common Stock as of the Expiration Time and (II) the number of
            shares of Common Stock outstanding (including any tendered shares)
            as of the Expiration Time less (B) the amount of cash plus the fair
            market value (determined as aforesaid) of the aggregate
            consideration payable to stockholders in the tender or exchange
            offer (assuming the acceptance, up to any maximum specified in the
            terms of the tender or exchange offer, of Purchased Shares), and
            (ii) the denominator of which shall be equal to the product of (A)
            the Current Market Price per share of the Common Stock as of the
            Expiration Time and (B) the number of shares of Common Stock
            outstanding (including any tendered shares) as of the Expiration
            Time less the number of all shares validly tendered and not
            withdrawn as of the Expiration Time (the shares deemed so accepted,
            up to any such maximum, being referred to as the "PURCHASED
            SHARES").

            All adjustments to the Conversion Rate, shall be calculated to the
      nearest 1/10,000th of a share of Common Stock (or if there is not a
      nearest 1/10,000th of a share to the next lower 1/10,000th of a share).

            (b) Effect of Reclassification, Consolidation, Merger, Combination
      or Sale.

            In the event of (i) any reclassification or change of outstanding
shares of Common Stock, (ii) any consolidation, merger or combination of the
Guarantor with another Person as a result of which holders of Common Stock shall
be entitled to receive stock, securities or other property or assets (including
cash) with respect to or in exchange for such Common Stock or (iii) any sale or
conveyance of all or substantially all of the property and assets of the
Guarantor to any other Person as a result of which holders of Common Stock shall
be entitled to receive stock, securities or other property or assets (including
cash) with respect to or in exchange for such Common Stock, then the Conversion
Rate will not be adjusted. If any of the events described in the preceding
sentence occur, the Guarantor or the successor or purchasing Person, as the case
may be, shall execute with the Trustee a supplemental indenture or otherwise
amend the terms of the Securities, to provide that each Security shall be
convertible into the kind and amount of shares of stock, other securities or
property or assets (including cash) that the Holder of the Security would have
received upon such reclassification, change, consolidation, merger, combination,
sale or conveyance if such Holder had converted such Security into the number of
shares of Common Stock issuable upon conversion of such Security immediately
prior to such reclassification, change, consolidation, merger, combination, sale
or conveyance. Such supplemental indenture or other amendment to the Securities
shall provide for adjustments that shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 1106. The above
provisions of this Section 1106(b) shall similarly apply to successive
reclassifications, changes, consolidations, mergers, combinations, sales and
conveyances. If this Section 1106(b) applies to any event or occurrence, Section
1106(a) shall not apply.

SECTION 1107. WHEN ADJUSTMENT MAY BE DEFERRED.

                                       70
<PAGE>
            No adjustment in the Conversion Rate need be made unless the
adjustment would require an increase or decrease of at least 1% in the
Conversion Rate. Any adjustments that are not made shall be carried forward and
taken into account in any subsequent adjustment.

SECTION 1108. WHEN NO ADJUSTMENT REQUIRED.

            Notwithstanding any provision of this Indenture to the contrary
herein, no adjustment to the Conversion Rate need be made as a result of:

            (a) (i) the issuance of the rights; (ii) the distribution of
separate certificates representing the rights; (iii) the exercise or redemption
of the rights in accordance with any rights agreement; or (iv) the termination,
expiration or invalidation of the rights, in each case, pursuant to any
Guarantor newly adopted stockholders rights plans;

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

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

            (d) the issuance of any shares of Common Stock pursuant to any
option, warrant, right, or exercisable, exchangeable or convertible security
outstanding as of the Original Issue Date.

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

            To the extent the Securities become convertible pursuant to this
Article Eleven in whole or in part into cash, assets or property (other than
capital stock or securities to which Section 1106(b) applies), no adjustment
need be made thereafter as to the cash, assets or property. Interest will not
accrue on such cash, assets or property.

SECTION 1109. NOTICE OF ADJUSTMENT.

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

SECTION 1110. VOLUNTARY INCREASE.

                                       71
<PAGE>
            (a) The Guarantor from time to time may increase the Conversion Rate
if the Board of Directors has made a determination that such increase would be
in the Guarantor's best interests (whose determination shall be conclusive) by
any amount at any time for at least 20 days, so long as the increase is
irrevocable during such period. Whenever the Conversion Rate is increased, the
Company shall mail to the Holders and file with the Trustee and the Conversion
Agent a notice of the increase. The Company shall mail the notice at least 15
days before the date the increased Conversion Rate takes effect. The notice
shall state the increased Conversion Rate and the period it will be in effect. A
voluntary increase of the Conversion Rate does not change or adjust the
Conversion Rate otherwise in effect for purposes of Section 1106(a).

            (b) The Guarantor may make such increases in the Conversion Rate, in
addition to those required by Section 1106(a), as it considers to be advisable
in order to avoid or diminish any income tax to any holders of shares of Common
Stock resulting from any dividend or distribution of stock or issuance of rights
or warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes or for any other reasons.

SECTION 1111. NOTICE OF CERTAIN TRANSACTIONS.

            If:

            (a) the Guarantor takes any action that would require an adjustment
in the Conversion Rate pursuant to Section 1106(a) (unless no adjustment is to
occur pursuant to Sections 1107 or 1108); or

            (b) the Guarantor takes any action that would require a supplemental
indenture pursuant to Section 1106(b); or

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

then the Company shall, subject to all applicable laws, mail to the Holders and
file with the Trustee and the Conversion Agent a notice stating the proposed
record date for a dividend or distribution or the proposed effective date of a
combination, subdivision, reclassification, consolidation, merger, amalgamation,
binding share exchange, transfer, liquidation or dissolution. The Company shall
file and mail the notice at least 15 days before such date. Failure to file or
mail the notice or any defect in it shall not affect the validity of the
transaction.

SECTION 1112. TRUSTEE'S ADJUSTMENT DISCLAIMER.

            The Trustee and any other Conversion Agent shall not at any time be
under any duty or responsibility to any Holder to either calculate the
Conversion Rate or determine 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 herein, or in any supplemental indenture provided to be employed, in
making the same and shall be protected in relying upon an Officer's Certificate
with respect to the same. The Trustee and any other Conversion Agent shall not
be accountable with respect to the validity or value (or the kind or amount) of
any shares of Common Stock, or of any securities or property (including cash),
which may at any time be issued or delivered upon the conversion of any
Securities and the Trustee and any other Conversion Agent make no
representations with respect

                                       72
<PAGE>
thereto. Neither the Trustee nor any Conversion Agent shall be responsible for
any failure of the Guarantor or the Company to issue, transfer or deliver any
shares of Common Stock or stock certificates or other securities or property or
cash upon the surrender of any Securities for the purpose of conversion or to
comply with any of the duties, responsibilities or covenants of the Company or
the Guarantor contained in this Article Eleven. 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 1106(b) relating
either to the kind or amount of shares of stock or securities or other property
or assets (including cash) receivable by Holders upon the conversion of their
Securities after any event referred to in such Section 1106(b) or to any
adjustment to be made with respect thereto, but, subject to the provisions of
Article Eight of the Indenture, may accept as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, the
Officer's Certificate (which the Company shall be obligated to file with the
Trustee prior to the execution of any such supplemental indenture) with respect
thereto. Neither the Trustee nor the Conversion Agent shall be responsible for
determining whether any event contemplated by the fifth paragraph of the reverse
of the form of Securities has occurred which makes the Securities eligible for
conversion or no longer eligible therefor until the Company has delivered to the
Trustee and the Conversion Agent an Officer's Certificate stating that such
event has occurred, on which certificate the Trustee and the Conversion Agent
may conclusively rely, and the Company agrees to deliver such Officer's
Certificate to the Trustee and the Conversion Agent immediately after the
occurrence of any such event. Such Officer's Certificate may be combined with
the notice to the Trustee provided for in Section 1101.

SECTION 1113. SUCCESSIVE ADJUSTMENTS.

            After an adjustment to the Conversion Rate under this Article
Eleven, any subsequent event requiring an adjustment under this Article Eleven
shall cause an adjustment to the Conversion Rate as so adjusted.

SECTION 1114. CALCULATIONS IN RESPECT OF THE SECURITIES.

            The Guarantor will be responsible for making all calculations called
for under the Securities. These calculations include, but are not limited to,
determination of the Applicable Stock Price, Current Market Price, Closing Sale
Price, Spin-off Market Price, Market Price, Sale Price, accrued interest payable
(including Additional Amounts) on the Securities and the Conversion Rate of the
Securities. The Guarantor will make these calculations in good faith and, absent
manifest error, these calculations will be final and biding on the Holders.
Promptly after the calculation thereof, the Guarantor will provide to each of
the Trustee, the Paying Agent and the Conversion Agent an Officer's Certificate
setting forth a schedule of its calculations and each of the Trustee, the Paying
Agent and the Conversion Agent is entitled to conclusively rely upon the
accuracy of such calculations without independent verification. The Trustee, the
Paying Agent and the Conversion Agent shall not be responsible for making any
calculation or determination referred to in this Section 1114. The Trustee will
forward the Guarantor's calculations to any Holder upon the request of such
Holder.

                                       73
<PAGE>
SECTION 1115. FUTURE STOCKHOLDER RIGHTS PLANS.

            If the Guarantor hereafter adopts any stockholder rights plan, upon
conversion of the Securities into shares of Common Stock pursuant to this
Article Eleven, a Holder shall be entitled to receive upon conversion of its
Securities, in addition to the shares of Common Stock issuable upon conversion,
the related rights for the Common Stock unless the rights have separated from
the Common Stock at the time of conversion, in which case the Conversion Rate
will be adjusted as if the Guarantor distributed to all holders of Common Stock,
shares of capital stock, evidences of indebtedness or assets, as described in
Section 1106(a)(4), subject to readjustment in the event of the expiration,
termination or redemption of such rights.

                                 ARTICLE TWELVE

upon which any Securities are listed, with the Commission and with the Company.
The Company will notify the Trustee when any Securities are listed on any stock
exchange.

            The Company and the Guarantor shall file with the Trustee (within
thirty (30) days after filing with the Commission in the case of reports that

      shall become effective with respect to the Securities only pursuant to the
      provisions of Section 1402 hereof; or

the Guarantor, when authorized by an Officer's Certificate, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of

directly affected,

            (a) change the Stated Maturity of the principal of, or any
      installment of principal of, or interest on, any Security (other than
      pursuant to the terms thereof), or reduce the principal amount thereof or
      the rate of interest thereon (or the amount of any installment of interest
      thereon) or change the coin or currency (or other property), in which any

      waived without the consent of the Holder of each Outstanding Security
      affected thereby.

            It shall not be necessary for any Act of Holders under this Section
1402 to approve the particular form of any proposed supplemental indenture, but
it shall be sufficient if such Act shall approve the substance thereof.

SECTION 1403. EXECUTION OF SUPPLEMENTAL INDENTURES.

            In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article Fourteen or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be entitled
to receive, and (subject to Section 801) shall be fully protected in relying
upon, an Opinion of Counsel and an Officer's Certificate stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture. The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture which

Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company, and authenticated and delivered by the Trustee in
exchange for Outstanding Securities.

any constitutional provision, statute or rule of law, or by the enforcement of
any assessment or penalty or otherwise. It being expressly agreed and understood
that this Indenture and all the Securities are solely obligations of the
Company, and the Guarantee is solely the obligation of the Guarantor and that no
personal liability whatsoever shall attach to, or be incurred by, officer,

      PPL ENERGY SUPPLY, LLC, a limited liability company duly organized and
existing under the laws of the State of Delaware (herein called the "Company,"
which term includes any successor under the Indenture referred to below), for
value received, hereby promises to pay to         , or registered assigns, the
principal sum of         DOLLARS ($      ), on the Stated Maturity shown above
and to pay interest thereon from the Original Issue Date shown above, or from
the most recent Interest Payment Date to which interest has been paid or duly
provided for, semi-annually in arrears on each Interest Payment Date as
specified above, commencing on November 15, 2003 and on the Stated Maturity at
the rate per annum shown above (the "Interest Rate") until the principal hereof
is paid or made available for payment and on any overdue principal and on any
overdue installment of interest. In addition, Additional Amounts may accrue on
this Security in the circumstances described in the Registration Rights
Agreement. The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in the Indenture, be paid to the
Person in whose name this 2 5/8% Convertible Senior Note due 2023 (this
"Security") is registered at the close of business on the Regular Record Date as
specified above next preceding such Interest Payment Date. Except as otherwise
provided in the Indenture, any such interest not so

                                      A-1
<PAGE>
punctually paid or duly provided for will forthwith cease to be payable to the
Holder on such Regular Record Date and may either be paid to the Person in whose
name this Security is registered at the close of business on a Special Record
Date for the payment of such Defaulted Interest to be fixed by the Trustee,
notice whereof shall be given to Holders of the Securities not less than 10 days
prior to such Special Record Date, or be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange, if
any, on which the Securities shall be listed, and upon such notice as may be
required by any such exchange, all as more fully provided in the Indenture.

      Payments of interest on this Security will include interest accrued to but
excluding the respective Interest Payment Dates. Payments of interest for this
Security shall be computed and paid on the basis of a 360-day year consisting of
twelve 30-day months and will accrue from May 21, 2003 or from the most recent
Interest Payment Date to which interest has been paid or duly provided for. In
the event that any date on which interest is payable on this Security is not a
Business Day, then payment of the interest payable on such date will be made on
the next succeeding day that is a Business Day (and without any interest or
payment in respect of any such delay) with the same force and effect as if made
on the date the payment was originally payable. "Business Day" means any day,
other than a Saturday or Sunday, that is not a day on which banking institutions
or trust companies are generally authorized or required by law, regulation or
executive order to close in The City of New York or other city in which any
Paying Agent is located.

      Payment of principal of and interest on the Securities shall be made in
such coin or currency of the United States of America as at the time of payment
is legal tender for payment of public and private debts.

      The Securities shall be redeemable, in whole or from time to time in part,
at the option of the Company on any date on or after May 20, 2008 (a "Redemption
Date"), at a Redemption Price equal to 100% of the principal amount of the
Securities to be redeemed plus any accrued and unpaid interest on the principal
amount to be redeemed to but excluding the Redemption Date. Notice of any
redemption by the Company will be mailed at least 30 days but not more than 60
days before any Redemption Date to each Holder of Securities to be redeemed. If
Notice of a redemption is provided and funds are deposited as required, interest
will cease to accrue on and after the Redemption Date on the Securities or
portions of Securities called for redemption. In the event that any Redemption
Date is not a Business Day, the Company will pay the Redemption Price on the
next Business Day without any additional interest or other payment due. If less
than all the Securities are to be redeemed at the option of the Company, the
Trustee shall select, in such manner as it shall deem fair and appropriate, the
Securities to be redeemed in whole or in part. The Trustee may select for
redemption Securities and portions of the Securities of this series in amounts
of whole multiples of $1,000.

      A Holder shall have the option to require the Company to purchase any or
all of the Securities held by such Holder on May 15, 2008, May 15, 2013 and May
15, 2018 (each, a "Purchase Date") at a purchase price (the "Purchase Price")
equal to the principal amount of the Securities to be purchased plus any accrued
and unpaid interest to, but excluding, the Purchase Date, upon delivery of a
Purchase Notice containing the information set forth in the Indenture, from the
opening of business on the date that is 20 Business Days prior to such Purchase
Date

                                      A-2
<PAGE>
until the close of business on the Purchase Date and upon delivery of the
Securities to the Paying Agent by the Holder as set forth in the Indenture. The
Company may, at its option, elect to pay the entire Purchase Price in cash or
shares of Common Stock.

      If a Fundamental Change shall occur at any time prior to Stated Maturity,
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 any or
all of such Holder's Securities or any portion of the principal amount thereof
that is equal to $1,000 or an integral multiple of $1,000 on the day that is 30
days after the date of the Fundamental Change Notice of the occurrence of the
Fundamental Change (subject to extension to comply with applicable law) for a
Fundamental Change Purchase Price equal to 100% of the principal amount of
Securities purchased plus accrued and unpaid interest to the Fundamental Change
Purchase Date upon delivery of a Fundamental Change Purchase Notice containing
the information set forth in the Indenture.

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

      If cash, or if applicable, shares of Common Stock, sufficient to pay a
Fundamental Change Purchase Price or Purchase Price, as the case may be, of all
Securities or portions thereof to be purchased as of the Fundamental Change
Purchase Date or the Purchase Date, as the case may be, is deposited with the
Paying Agent on the Business Day following the Fundamental Change Purchase Date
or the Purchase Date, as the case may be, interest shall cease to accrue on such
Securities (or portions thereof) on and after such date, and the Holder thereof
shall have no other rights as such (other than the right to receive the
Fundamental Change Purchase Price or Purchase Price, as the case may be, upon
surrender of such Security).

      The Securities shall not have a sinking fund.

      The Securities shall constitute the direct unsecured and unsubordinated
debt obligations of the Company and shall rank equally in priority with the
Company's existing and future unsecured and unsubordinated indebtedness.

      REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

TRUSTEE'S CERTIFICATE OF
  AUTHENTICATION

This is one of the Securities referred to
in the within-mentioned Indenture.

JPMORGAN CHASE BANK,
   as Trustee,

By: ____________________________
    Authorized Officer

Date:

                                      A-4
<PAGE>
                             (Reverse of Security)

                    2 5/8% Convertible Senior Note due 2023

      1. This 2 5/8% Convertible Senior Note due 2023 is one of a duly
authorized issue of Securities of the Company (the "Securities"), issued and
issuable under an Indenture, dated as of May 21, 2003 (the "Indenture"), between
the Company, PPL Corporation, as guarantor (the "Guarantor"), and JPMorgan Chase
Bank, as Trustee (the "Trustee," which term includes any successor trustee under
the Indenture), to which Indenture reference is hereby made for a statement of
the respective rights, limitation of rights, duties and immunities thereunder of
the Company, the Guarantor, the Trustee and the Holders of the Securities issued
thereunder and of the terms upon which said Securities are, and are to be,
authenticated and delivered. The 2 5/8% Convertible Senior Notes due 2023 are
issuable in the aggregate principal amount of $400,000,000. Capitalized terms
used herein for which no definition is provided herein shall have the meanings
set forth in the Indenture.

      2. To guarantee the full and punctual payment of the principal of, and
interest on, the Securities and all other amounts payable by the Company under
the Indenture and the Securities when and as the same shall be due and payable,
whether at maturity, by acceleration or otherwise, according to the terms of the
Securities and the Indenture, the Guarantor has unconditionally guaranteed such
obligations pursuant to the terms of the Indenture. The Guarantee is an
unsecured and unsubordinated obligation of the Guarantor and ranks equally with
all other unsecured and unsubordinated indebtedness and obligations of the
Guarantor. In addition, the Guarantor has unconditionally guaranteed the
conversion obligations of the Company to deliver shares of Common Stock pursuant
to the Indenture and this Security.

      3. Principal on Definitive Securities shall be payable in immediately
available funds or, at the option of the Company, at the office or agency of the
Company maintained for such purpose, initially the Corporate Trust Office of the
Trustee. Interest and Additional Amounts, if any, on Definitive Securities will
be payable at the Company's option (A) to Holders having an aggregate principal
amount of Securities of $2,000,000 or less, by check mailed to the Holders of
such Securities at the address therefore in the Security Register and (B) to
Holders having an aggregate principal amount of Securities of more than
$2,000,000, either by check mailed to each such Holder at the address therefore
in the Security Register or, upon application by any such Holder to the Security
Registrar not later than the relevant Regular Record Date, by wire transfer in
immediately available funds to that Holder's account within the United States
specified in such application, which application shall remain in effect until
the Holder notifies, in writing, the Security Registrar to the contrary.

      4. Initially, JPMorgan Chase Bank will act as Trustee, Paying Agent,
Conversion Agent and Security Registrar. The Company may appoint and change any
Paying Agent, Conversion Agent, Security Registrar or co-registrar without
notice to any Holder. The Guarantor, the Company or any other Subsidiary of the
Guarantor or the Company may act as Paying Agent, Security Registrar or
co-registrar.

                                      A-5
<PAGE>
      5. Holders may surrender any of their Securities for conversion into
shares of Common Stock, on the terms and subject to the conditions of the
Indenture and this Security, in only the following circumstances:

            (a) A Holder may surrender for conversion a Security prior to close
      of business on the date of Stated Maturity during any fiscal quarter
      commencing after June 30, 2003, if the Closing Sales Price of the shares
      of Common Stock for at least 20 Trading Days in the 30 consecutive Trading
      Day period ending on the last Trading Day of the immediately preceding
      fiscal quarter exceeds 120% of the applicable Conversion Price per share
      of Common Stock on the last Trading Day of the immediately preceding
      fiscal quarter.

            (b) After the earlier of (x) the date the Securities are rated by
      both Moody's Investors Service, Inc. and Standard & Poor's Ratings
      Services and (y) May 31, 2003, a Holder may surrender for conversion a
      Security prior to the close of business on the date of Stated Maturity
      during any period in which (i) the long-term credit rating assigned to the
      Securities by both Moody's Investors Service, Inc. and Standard & Poor's
      Ratings Services is lower than "Ba2" or "BB", respectively; (ii) both
      Moody's Investors Service, Inc. and Standard & Poor's Ratings Services no
      longer rate the Securities or have withdrawn their ratings with respect to
      the Securities; or (iii) either Moody's Investors Service, Inc. or
      Standard & Poor's Ratings Services no longer rates the Securities or have
      withdrawn or suspended such rating and the remaining rating is lower than
      "Ba2" or "BB", as applicable.

            (c) In the event that the Company calls any Securities for
      redemption, a Holder may surrender for conversion a Security prior to the
      close of business on the Business Day immediately preceding the Redemption
      Date, after which time the right of the Holder to convert will expire
      unless the Company defaults in the payment of the Redemption Price, in
      which case the conversion right shall terminate at the time such payment
      is made.

            (d) In the event the Guarantor is a party to a consolidation,
      merger, binding share exchange or sale of all or substantially all of its
      assets, pursuant to which the shares of Common Stock would be converted
      into cash, securities or other property, the Securities may be surrendered
      for conversion at any time from and after the date which is 15 days prior
      to the date the Guarantor announces as the anticipated effective date for
      such transaction until and including the date which is 15 days after the
      actual date of such transaction. If the Guarantor is a party to a
      consolidation, merger, binding share exchange or sale of all or
      substantially all of its assets, in each case pursuant to which Common
      Stock is converted into cash, securities, or other property, then at the
      effective time of the transaction, the Holder's right to convert a
      Security into Common Stock will be changed into a right to convert it into
      the kind and amount of cash, securities or other property which the Holder
      would have received if such Holder had converted its Securities
      immediately prior to the transaction.

            (e) If the Guarantor elects to (1) distribute any rights or warrants
      to all holders of shares of Common Stock entitling them to purchase, for a
      period expiring within 45

                                      A-6
<PAGE>
      days, shares of Common Stock at less than the average of the Sale Prices
      of a share of Common Stock for the 10 consecutive Trading Days ending on
      the Trading Day immediately preceding the date of declaration for such
      distribution; or (2) distributes to all holders of shares of Common Stock
      any of its debt, securities or assets or any rights, warrants or options
      to purchase securities of the Guarantor, which distribution has a per
      share value exceeding 10% of the Sale Price of a share of Common Stock on
      the Trading Day immediately preceding the declaration date for such
      distribution. In the case of the foregoing clauses (1) and (2), the
      Company must notify the Holders at least 20 Business 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
      thereafter until the earlier of close of business on the Business Day
      prior to the ex-dividend date or any announcement by the Guarantor that
      such distribution will not take place. No adjustment to a Holder's ability
      to convert will be made if such Holder will otherwise participate in the
      distribution without conversion.

      6. No payment or adjustment will be made for dividends on, or other
distributions with respect to, any shares of Common Stock except as provided in
Article Eleven of the Indenture. Upon conversion of a Security, except as
provided in the Indenture with respect to interest payable on Securities or
portions thereof converted after a Regular Record Date, that portion of accrued
and unpaid interest on the converted Securities attributable to the period from
the most recent Interest Payment Date through the Conversion Date shall not be
cancelled, extinguished or forfeited, but rather shall be deemed to be paid in
full to the Holder thereof through delivery of the shares of Common Stock
(together with the cash payment, if any, in lieu of fractional shares) for the
Security being converted pursuant to the provisions hereof. The Company will not
adjust the Conversion Rate to account for accrued interest, if any.

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

      8. The initial Conversion Rate is 20.1106 shares of Common Stock per
$1,000 principal amount of Securities, subject to adjustment in certain events
described in the Indenture. A Holder that surrenders Securities for conversion
will receive cash in lieu of any fractional shares of Common Stock.

      9. To surrender a Security for conversion, a Holder must (1) complete and
manually sign the irrevocable (except as provided in Section 1102 of the
Indenture) conversion notice substantially in the form attached hereto (or
complete and manually sign a facsimile of such notice) and deliver such notice
to the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3)
if required, furnish appropriate endorsements and transfer documents, (4) if
required, pay any transfer or similar tax, and (5) if required, pay funds equal
to interest payable on the next Interest Payment Date.

      10. A Holder may convert a portion of a Security if the principal amount
of such portion is $1,000 or an integral multiple of $1,000. No payment or
adjustment will be made for dividends on the shares of Common Stock except as
provided in the Indenture. On conversion of

                                      A-7
<PAGE>
a Security, the Holder will not receive any cash payment representing accrued
interest with respect to the converted Securities. Instead, upon conversion the
Company will deliver to the Holder a fixed number of shares of Common Stock and
any cash payment to account for fractional shares. Accrued interest will be
deemed paid in full rather than canceled, extinguished or forfeited. Neither the
Company nor the Guarantor will adjust the Conversion Rate to account for accrued
interest.

      11. The Conversion Rate will be adjusted as provided in Article Eleven of
the Indenture.

      12. The Securities are in registered form without coupons in denominations
of $1,000 and multiples of $1,000. A Holder may transfer or exchange Securities
in accordance with the Indenture. The Security 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. In
the event of any redemption of fewer than all of the outstanding Securities, the
Security Registrar need not register the transfer of or exchange any Securities
selected for redemption (except, in the case of a Security to be redeemed in
part, the portion of the Security not to be redeemed) or issue, register the
transfer of or exchange any Securities for a period of 15 days before the
mailing of the redemption notice. In addition, the Security Registrar need not
register the transfer of or exchange any Securities in respect of which a
Purchase Notice or Fundamental Change Purchase Notice has been given and not
withdrawn (except, in the case of a Security to be purchased in part, the
portion of the Security not to be purchased).

      13. The registered Holder of this Security may be treated as the owner of
it for all purposes (subject to Section 208 of the Indenture).

      14. The Trustee and the Paying Agent shall return to the Company upon
Company Request any money or property held by them for the payment of any amount
with respect to the Securities that remains unclaimed for two years, provided,
however, that the Trustee or such Paying Agent, before being required to make
any such payment to the Company, may at the expense of the Company, either (a)
cause to be mailed, on one occasion only, notice to such Holder that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such mailing, any unclaimed balance of such
money then remaining will be paid to the Company or (b) cause to be published
once, in a newspaper published in the English language, customarily published on
each Business Day and of general circulation in the Borough of Manhattan, The
City of New York, notice that such money remains unclaimed and that after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be paid to
the Company.

      15. The Indenture or the Securities may be amended with the written
consent of the Holders of at least a majority in principal amount of the then
outstanding Securities; provided, however, that the consent of each Holder
affected is required to (i) change the stated maturity of the principal or
interest on the Security, or reduce the principal amount or interest payable or
change the currency in which the Securities are payable, or impair the right to
bring suit to enforce any payment, (ii) reduce the percentage of holders whose
consent is required for any supplemental indenture or waiver, (iii) modify
certain terms of the conversion rights under the

                                      A-8
<PAGE>
Indenture as set forth in the Indenture, or (iv) modify the provisions of the
Indenture relating to supplemental indentures and waivers of past defaults.

      16. Subject to certain exceptions set forth in the Indenture, without the
consent of any Holder, the Company, the Guarantor and the Trustee may amend the
Indenture or the Securities to cure any ambiguity, omission, defect or
inconsistency, or to comply with Articles Ten and Thirteen of the Indenture, or
to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional provisions for the benefit of the
Holders, or to add additional covenants of the Company or the Guarantor, or
surrender rights and powers conferred on the Company or the Guarantor, or to
comply with any request of the SEC in connection with qualifying the Indenture
under the Trust Indenture Act, to make provisions with respect to the conversion
right in the event of an occurrence pursuant to Articles Ten or Thirteen of the
Indenture, or to make any change that does not adversely affect the rights of
any Holder.

      17. Subject to certain exceptions set forth in the Indenture, any default
(other than with respect to nonpayment or in respect of a provision that cannot
be amended without the written consent of each Holder affected) may be waived
with the written consent of the Holders of a majority in principal amount of the
then outstanding Securities.

      18. Under the Indenture, Events of Default include (1) default for 30 days
in payment of interest when due on the Securities; (2) default in payment of
principal on the Securities at Stated Maturity, upon required repurchase or upon
optional redemption, upon declaration or otherwise; (3) the failure to deliver
shares of Common Stock upon the due exercise of the conversion right in the
Securities; (4) default in the performance of, or breach of, any covenant or
warranty of the Company or the Guarantor in the Indenture and continuance of
such default or breach for a period of 60 days after there has been given, a
written notice specifying such default or breach and requiring it to be remedied
and stating that such notice is a "Notice of Default"; (5) a matured event of
default, as defined in any of the Company's or Guarantor's instruments under
which there may be issued or evidenced any debt of the Company or the Guarantor,
as applicable, that has resulted in the acceleration of such debt, in excess of
$40,000,000 or any default in payment of debt in excess of $40,000,000 at the
final maturity (and after the expiration of any applicable grace or cure
periods); provided that the waiver or cure of any default under any such
instrument and the rescission and annulment of the consequences thereof shall
constitute a waiver or cure of the corresponding default under the Indenture and
a rescission and annulment of the corresponding consequences under the
Indenture; (6) certain events of bankruptcy, insolvency or reorganization of the
Company or the Guarantor (the "bankruptcy events"). However, a default under
clause (4) will not constitute an Event of Default until the Trustee or the
Holders of at least 25% in principal amount of the outstanding Securities notify
the Company or the Guarantor, as the case may be, of the default and the Company
or the Guarantor, as the case may be, does not cure such default within the time
specified in clause (4) hereof after receipt of such notice.

      19. If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities by written notice to the Company to be due and payable
immediately.

                                      A-9
<PAGE>
      20. Holders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives indemnity or security reasonably satisfactory
to the Trustee. 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 Holders notice of any continuing
default or Event of Default (except a default or Event of Default in payment of
principal or interest) if it determines that withholding notice is in their
interest.

      21. 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.

      22. The Guarantor will be responsible for making all calculations called
for under the Securities. These calculations include, but are not limited to,
determination of the Applicable Stock Price, Current Market Price, Closing Sale
Price, Spin-off Market Price, Market Price, Sale Price, accrued interest payable
(including Additional Amounts) on the Securities and the Conversion Rate of the
Securities. The Guarantor will make these calculations in good faith and, absent
manifest error, these calculations will be final and biding on the Holders. The
Guarantor will be required to deliver to each of the Trustee, the Paying Agent
and the Conversion Agent a schedule of its calculations and each of the Trustee,
the Paying Agent and the Conversation Agent will be entitled to rely upon the
accuracy of such calculations without independent verification. The Trustee will
forward the Guarantor's calculations to any Holder upon the request of such
Holder.

      23. No recourse shall be had for the payment of the principal of, or
interest on, any Securities or any part thereof, or for any claim based thereon
or otherwise in respect thereof, or of the indebtedness represented thereby, or
upon any obligation, covenant or agreement under this Indenture, against any
officer, member, manager or director, as such, past, present or future of the
Company, the Guarantor or of any predecessor or successor of the Company or the
Guarantor (either directly or through the Company, the Guarantor or a
predecessor or successor of the Company or the Guarantor), whether by virtue of
any constitutional provision, statute or rule of law, or by the enforcement of
any assessment or penalty or otherwise. It being expressly agreed and understood
that this Indenture and all the Securities are solely obligations of the
Company, and the Guarantees are solely obligations of the Guarantor and that no
personal liability whatsoever shall attach to, or be incurred by, officer,
member, manager or director, past, present or future, of the Company, the
Guarantor or of any predecessor or successor of the Company or the Guarantor,
either directly or indirectly through the Company, the Guarantor or any
predecessor or successor of the Company or the Guarantor, because of the
indebtedness hereby authorized or under or by reason of any of the obligations,
covenants or agreements contained in this Indenture or in any of the Securities
or to be implied herefrom or therefrom, and that any such personal liability is
hereby expressly waived and released as a condition of, and as part of the
consideration for, the execution of this Indenture and the issuance of the
Securities.

                          FIRST SUPPLEMENTAL INDENTURE

         FIRST SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as
of May 7, 2003, by and among the entities listed on Schedule 1 attached hereto
(the "Guaranteeing Subsidiaries"), each being a subsidiary of Peabody Energy
Corporation (or its permitted successor), a Delaware corporation (the
"Company"), the Company, the other Subsidiary Guarantors (as defined in the
Indenture referred to herein) and US Bank National Association, as Trustee under
the Indenture referred to below (the "Trustee").

                                   WITNESSETH

         WHEREAS, the Company has heretofore executed and delivered to the
Trustee an Indenture (the "Indenture"), dated as of March 21, 2003 providing for
the issuance of an unlimited amount of 6-7/8% Notes due 2013 (the "Notes");

         WHEREAS, the Indenture provides that under certain circumstances the
Guaranteeing Subsidiaries shall execute and deliver to the Trustee a
supplemental indenture pursuant to which the Guaranteeing Subsidiaries shall
unconditionally guarantee all of the Company's Obligations under the Notes on
the terms and conditions set forth herein (the "Subsidiary Guarantee"); and

         WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

         NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the
Guaranteeing Subsidiaries and the Trustee mutually covenant and agree for the
equal and ratable benefit of the Holders of the Notes as follows:

                           (i)      the principal of and interest on the Notes
                                    will be promptly paid in full when due,

                                    hereunder or thereunder will be promptly
                                    paid in full or performed, all in accordance
                                    with the terms hereof and thereof; and

                           (ii)     in case of any extension of time of payment
                                    or renewal of any Notes or any of such other
                                    obligations, that same will be promptly paid
                                    in full when due or performed in accordance

                           Subsidiary Giarantor agrees that this is a guarantee
                           of payment and not a guarantee of collection.

                  (b)      The obligations hereunder shall be joint and several

                           Company under the Indenture, the absence of any
                           action to enforce the same, any waiver or consent by
                           any Holder of the Notes with respect to any
                           provisions hereof or thereof, the recovery of any
                           judgment against the Company, any action to enforce
                           the same or any other circumstance which might
                           otherwise constitute a legal or equitable discharge
                           or defense of a Subsidiary Guarantor.

                  (c)      The following is hereby waived: diligence,
                           presentment, demand of payment, filing of claims with

                           the Company, any right to require a proceeding first
                           against the Company, protest, notice and all demands
                           whatsoever.

                           except by complete performance of the obligations
                           contained in the Notes and the Indenture.

                  (e)      If any Holder or the Trustee is required by any court
                           or otherwise to return to the Company, the Subsidiary
                           Guarantors, or any custodian, Trustee, liquidator or
                           other similar official acting in relation to either
                           the Company or the Subsidiary Guarantors, any amount
                           paid by either to the Trustee or such Holder, this
                           Subsidiary Guarantee, to the extent theretofore
                           discharged, shall be reinstated in full force and
                           effect.

                           Subsidiary Guarantee.

                  (h)      The Subsidiary Guarantors shall have the right to

                           Guarantor so long as the exercise of such right does
                           not impair the rights of the Holders under the

         3.       EXECUTION AND DELIVERY. Each of the Guaranteeing Subsidiaries
agrees that the Subsidiary Guarantees shall remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such
Subsidiary Guarantee.

         4.       GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN

                                    unconditionally assumes all the obligations
                                    of such Subsidiary Guarantor, pursuant to a
                                    supplemental Indenture in form and substance
                                    reasonably satisfactory to the Trustee,

                                    herein or therein; and

                           (ii)     immediately after giving effect to such
                                    transaction, no Default or Event of Default
                                    exists.

                           conveyance and upon the assumption by the successor
                           corporation, by supplemental Indenture, executed and

                           upon the Notes and the due and punctual performance

                           thereupon may cause to be signed any or all of the

                           Notes issuable hereunder which theretofore shall not
                           have been signed by the Company and delivered to the
                           Trustee. All the Subsidiary Guarantees so issued
                           shall in all respects have the same legal rank and
                           benefit under the Indenture as the Subsidiary
                           Guarantees theretofore and thereafter issued in
                           accordance with the terms of the Indenture as though
                           all of such Subsidiary Guarantees had been issued at
                           the date of the execution hereof.

                           Indenture, and notwithstanding clauses (a) and (b)
                           above, nothing contained in the Indenture or in any
                           of the Notes shall prevent any consolidation or
                           merger of a Subsidiary Guarantor with or into the

                           prevent any sale or conveyance of the property of a
                           Subsidiary Guarantor as an entirety or substantially
                           as an entirety to the Company or another Subsidiary
                           Guarantor.

                  (a)      In the event of a sale or other disposition of all of
                           the assets of any Subsidiary Guarantor, by way of
                           merger, consolidation or otherwise, or a sale or

                           disposition of all or substantially all of the assets
                           of such Subsidiary Guarantor) will be released and
                           relieved of any obligations under its Subsidiary
                           Guarantee; provided that the Net Proceeds of such
                           sale or other disposition are applied in accordance
                           with the applicable provisions of the Indenture,
                           including without limitation Section 4.10 of the
                           Indenture. Upon delivery by the Company to the
                           Trustee of an Officer's Certificate and an Opinion of
                           Counsel to the effect that such sale or other
                           disposition was made by the Company in accordance
                           with the provisions of the Indenture, including
                           without limitation Section 4.10 of the Indenture, the
                           Trustee shall execute any documents reasonably
                           required in order to evidence the release of any
                           Subsidiary Guarantor from its obligations under its
                           Subsidiary Guarantee.

                  (b)      Any Subsidiary Guarantor not released from its
                           obligations under its Subsidiary Guarantee shall
                           remain liable for the full amount of principal of and
                           interest on the Notes and for the other obligations
                           of any Subsidiary Guarantor under the Indenture as
                           provided in Article 10 of the Indenture.

         6.       NO RECOURSE AGAINST OTHERS. No past, present or future
director, officer, employee, incorporator, stockholder or agent of the
Guaranteeing Subsidiaries, as such, shall have any liability for any obligations
of the Company or any of the Guaranteeing Subsidiaries under the Notes, any
Subsidiary Guarantees, the Indenture or this Supplemental Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of the Notes by accepting a Note waives and releases all
such liability. The waiver and release are part of the consideration for
issuance of the Notes. Such waiver may not be effective to waive liabilities
under the federal securities laws and it is the view of the Commission that such
a waiver is against public policy.

         7.       NEW YORK LAW TO GOVERN. THE LAW OF THE STATE OF NEW YORK SHALL
GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE.

         8.       COUNTERPARTS. The parties may sign any number of copies of
this Supplemental Indenture. Each signed copy shall be an original, but all of
them together represent the same agreement.

         9.       EFFECT OF HEADINGS. The Section headings herein are for
convenience only and shall not affect the construction hereof.
