                  (25)     if applicable, that the Securities of the Series, in
whole or any specified part, shall be convertible into equity securities of the
Company

         All Securities of any one Series need not be issued at the same time
and may be issued from time to time, consistent with the terms of this
Indenture, if so provided by or pursuant to the Board Resolution, supplemental
indenture or Officers' Certificate referred to above, and the authorized
principal amount of any Series may not be increased to provide for issuances of
additional Securities of such Series, unless otherwise provided in such Board
Resolution, supplemental indenture or Officers' Certificate.

         2.3      EXECUTION AND AUTHENTICATION.

         The Securities shall be executed on behalf of the Company by two
Officers of the Company or an Officer and an Assistant Secretary of the Company.
Each such signature may be either manual or facsimile. The Company's seal may be
impressed, affixed, imprinted or reproduced on the Securities and may be in
facsimile form.

         If an Officer whose signature is on a Security no longer holds that
office at the time the Security is authenticated, the Security shall
nevertheless be valid. A Security shall not be valid until authenticated by the
manual signature of the Trustee or an authenticating agent. The signature shall
be conclusive evidence that the Security has been authenticated under this
Indenture.

         The Trustee shall at any time, and from time to time, authenticate
Securities for original issue in the principal amount provided in the Board
Resolution, supplemental indenture hereto or Officers' Certificate, upon receipt
by the Trustee of a Company Order. Such Company Order may authorize
authentication and delivery pursuant to oral or electronic instructions from the
Company or its duly authorized agent or agents, which oral instructions shall be
promptly confirmed in writing. Each Security shall be dated the date of its
authentication unless otherwise provided by a Board Resolution, a supplemental
indenture hereto or an Officers' Certificate.

         The aggregate principal amount of Securities of any Series outstanding
at any time may not exceed any limit upon the maximum principal amount for such
Series set forth in the Board Resolution, supplemental indenture hereto or
Officers' Certificate delivered pursuant to Section 2.2, except as provided in
Section 2.8.

         Prior to the issuance of Securities of any Series, the Trustee shall
have received and (subject to Section 7.2) shall be fully protected in relying
on: (a) the Board Resolution, supplemental indenture hereto or Officers'
Certificate establishing the form of the Securities of that Series or of
Securities within that Series and the terms of the Securities of

                                     - 9 -

<PAGE>

that Series or of Securities within that Series, (b) an Officers' Certificate
complying with Section 10.4, and (c) an Opinion of Counsel complying with
Section 10.4.

         The Trustee shall have the right to decline to authenticate and deliver
any Securities of such Series: (a) if the Trustee, being advised in writing by
outside counsel, determines that such action may not lawfully be taken; or (b)
if the Trustee in good faith by its board of directors or trustees, executive
committee or a trust committee of directors and/or vice-presidents shall
reasonably determine that such action would expose the Trustee to personal
liability, or cause it to have a conflict of interest with respect to Holders of
any then outstanding Series of Securities.

         The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate Securities. An authenticating agent may
authenticate Securities whenever the Trustee may do so. Any appointment shall be
evidenced by instrument signed by an authorized officer of the Trustee, a copy
of which shall be furnished to the Company. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company.

         2.4      REGISTRAR AND PAYING AGENT.

         The Company shall maintain an office or agency where Securities of any
Series may be presented for registration of transfer or for exchange
("Registrar"), an office or agency located in the Borough of Manhattan, City of
New York, State of New York where Securities may be presented for payment
("Paying Agent"), and an office or agency where notices and demands to or upon
the Company in respect of the Securities and this Indenture may be served
("Service Agent"). The Registrar shall keep a register of the Securities and of
their transfer and exchange. The Company may have one or more co-registrars and
one or more additional paying agents. The Company shall give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such
required office or to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
address of the Trustee as set forth in Section 10.2. Neither the Company nor any
Affiliate of the Company may act as Paying Agent. The Company may change any
Paying Agent, Registrar or co-registrar without notice to any Securityholder.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations. The
Company shall give prompt written notice to the Trustee of such designation or
rescission and of any change in the location of any such other office or agency.

The Company shall enter into an appropriate agency agreement with any Registrar
or Paying Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall notify
the Trustee of the name and address of any such Agent. If the Company fails to
maintain a Registrar or Paying Agent, or agent for service of notices and
demands, or fails to give the foregoing notice, the Trustee shall

                                     - 10 -

<PAGE>

act as such. The Company hereby appoints the Trustee as the initial Registrar,
Paying Agent and Service Agent for each Series unless another Registrar, Paying
Agent or Service Agent, as the case may be, is appointed prior to the time
Securities of that Series are first issued. The Company hereby initially
designates the Corporate Trust Office of the Trustee as such office of the
Company. The Company further designates Wachovia Bank of Delaware, National
Association, as the Paying Agent, with offices at 9300 Shelbyville Road, Suite
507, Louisville, KY 40222.

         2.5      PAYING AGENT TO HOLD ASSETS IN TRUST.

         The Trustee as Paying Agent shall, and the Company shall require each
Paying Agent other than the Trustee to agree in writing that each Paying Agent
shall hold in trust for the benefit of the Holders of any Series of Securities
or the Trustee all assets held by the Paying Agent for the payment of principal
of, or interest or premium (if any) on, such Series of Securities (whether such
assets have been distributed to it by the Company or any other obligor on such
Series of Securities), and the Company and the Paying Agent shall notify the
Trustee in writing of any Default by the Company (or any other obligor on such
Series of Securities) in making any such payment. The Company at any time may
require a Paying Agent to distribute all assets held by it to the Trustee and
account for any assets disbursed and the Trustee may at any time during the
continuance of any payment default with respect to any Series of Securities,
upon written request to a Paying Agent, require such Paying Agent to distribute
all assets held by it to the Trustee and to account for any assets distributed.
Upon distribution to the Trustee of all assets that shall have been delivered by
the Company to the Paying Agent, the Paying Agent shall have no further
liability for such assets.

         2.6      SECURITYHOLDER LISTS.

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Securityholders of each Series of Securities. If the Trustee is not the
Registrar, the Company shall furnish to the Trustee as of each regular record
date for the payment of interest on the Securities of a Series and before each
related Interest Payment Date, and at such other times as the Trustee may
request in writing, a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of Securityholders of each Series
of Securities.

         2.7      TRANSFER AND EXCHANGE.

         When Securities of a Series are presented to the Registrar with a
request to register the transfer thereof, the Registrar shall register the
transfer as requested, and when such Securities of a Series are presented to the
Registrar with a request to exchange them for an equal principal amount of other
authorized denominations of Securities of the same Series, the Registrar shall
make the exchange as requested. To permit transfers and exchanges, upon
surrender of any Security for registration of transfer at the office or agency
maintained pursuant to Section 2.4 hereof, the Company shall execute and the
Trustee shall authenticate Securities at the Registrar's request.

                                     - 11 -

<PAGE>

         Notwithstanding any other provision of this Section 2.7, unless and
until it is exchanged in whole or in part for definitive Securities, a Global
Security may not be transferred except as a whole by the Depositary to a nominee
of such Depositary or by a nominee of such Depositary to such Depositary or
another nominee of such Depositary or by such Depositary or any such nominee to
a successor Depositary or a nominee of such successor Depositary.

         If (i) the Depositary is at any time unwilling, unable or ineligible to
continue as Depositary and a successor Depositary is not appointed by the
Company within 90 days after the date the Company is so informed in writing or
becomes aware of the same, or (ii) a Default or an Event of Default has occurred
and is continuing, the Company promptly will execute and deliver to the Trustee
definitive Securities, and the Trustee, upon receipt of a Company Request for
the authentication and delivery of such definitive Securities (which the Company
will promptly execute and deliver to the Trustee), will authenticate and deliver
definitive Securities, without charge, in an aggregate principal amount equal to
the principal amount of the outstanding Global Securities, in exchange for and
upon surrender of all such Global Securities.

         In any exchange provided for in the preceding paragraph, the Company
will execute and the Trustee will authenticate and deliver definitive Securities
in the authorized denominations provided by Section 2.3.

         Upon the exchange of a Global Security for definitive Securities, such
Global Security shall be canceled by the Trustee. Definitive Securities issued
in exchange for Global Securities pursuant to this Section 2.7 shall be
registered in such names and in such authorized denominations as the Depositary,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee.

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

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

         Any exchange or transfer shall be without charge, except that the
Company may require payment by the Holder of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation to a transfer or
exchange, but this provision shall not apply to any exchange pursuant to Section
2.11, 3.6 or 8.5 hereof. The Trustee shall not be required to register transfers
of Securities of any Series or to exchange Securities of any Series for a period
of 15 days before selection for redemption of such Securities. The Trustee shall
not be required to exchange or register transfers of Securities of any Series
called or being called for redemption in whole or in part, except the unredeemed
portion of such Security being redeemed in part.

         2.8      REPLACEMENT SECURITIES.

         If a mutilated Security is surrendered to the Trustee or if the Holder
of a Security presents evidence to the satisfaction of the Company and the
Trustee that the Security has been lost, destroyed or wrongfully taken, the
Company shall issue and the Trustee shall authenticate a replacement Security of
the same Series and of like tenor and principal amount and bearing a number not
contemporaneously outstanding. An indemnity bond may be required by the Company
or the Trustee that is sufficient in the reasonable judgment of the Company or
the Trustee, as the case may be, to protect the Company, the Trustee or any
Agent from any loss which any of them may suffer if a Security is replaced. The
Company may charge such Holder for its reasonable, out-of-pocket expenses in
replacing a Security, including the fees and expenses of counsel. Every
replacement Security shall constitute an additional obligation of the Company,
whether or not the destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionally with any and all other Securities of that
Series duly issued hereunder.

         2.9      OUTSTANDING SECURITIES.

         Securities outstanding at any time are all Securities authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, and those described in this Section 2.9 as not outstanding.

         If a Security is replaced pursuant to Section 2.8 (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding
until the Company and the Trustee receive proof satisfactory to each of them
that the replaced Security is held by a bona fide purchaser. A mutilated
Security ceases to be outstanding upon surrender of such Security and
replacement thereof pursuant to Section 2.8.

         If a Paying Agent holds on a Redemption Date or Maturity Date of a
Series of Securities money sufficient to pay the principal of, premium, if any,
and accrued interest on Securities payable on that date and is not prohibited
from paying such money to the Holders thereof pursuant to the terms of this
Indenture, then on and after that date such Securities cease to be outstanding
and interest on them ceases to accrue.

         Subject to Section 2.10, a Security does not cease to be outstanding
solely because the Company or an Affiliate holds the Security.

         2.10     TREASURY SECURITIES.

         In determining whether the Holders of the required principal amount of
Securities of a Series have concurred in any request, demand, authorization,
direction, notice, consent or waiver, Securities of a Series owned by the
Company or an Affiliate shall be disregarded, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
request, demand, authorization, direction, notice, consent or waiver only
Securities of a Series that the Trustee knows are so owned shall be so
disregarded.

<PAGE>

         2.11     TEMPORARY SECURITIES.

         Until definitive Securities are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form, and shall carry all rights, of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities in
exchange for temporary Securities presented to it.

         2.12     CANCELLATION.

         The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for transfer, exchange or payment. At the
direction of the Trustee, the Registrar or the Paying Agent, and no one else,
shall cancel and at the written request of the Company, shall dispose of all
Securities surrendered for transfer, exchange, payment or cancellation. If the
Company shall acquire any of the Securities, such acquisition shall not operate
as a redemption or satisfaction of the Indebtedness represented by such
Securities unless and until the same are surrendered to the Trustee for
cancellation pursuant to this Section 2.12.

         2.13     PAYMENT OF INTEREST; DEFAULTED INTEREST; COMPUTATION OF
INTEREST.

         Except as otherwise provided as contemplated by Section 2.2 with
respect to any Series of 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 is registered at the close of
business on the regular record date for such interest, as provided in the Board
Resolution, supplemental indenture hereto or Officers' Certificate establishing
the terms of such Series.

         With respect to any Holder with an aggregate principal amount of
Securities of any Series in an amount in excess of $2,000,000, upon receipt by
the Trustee of a written request from such Holder, payments of interest with
respect to such Securities shall be made to such Holder by wire transfer of
immediately available funds. Each other Holder shall receive payments of
interest by check or by transfer to an account maintained by such Holder in the
United States.

         If the Company defaults in a payment of interest on the Securities, it
shall pay the defaulted amounts, plus any interest payable on defaulted amounts
pursuant to Section 4.1 hereof, to the persons who are Securityholders on a
subsequent special record date, which date shall be the fifteenth day next
preceding the date fixed by the Company for the payment of defaulted interest or
the next succeeding Business Day if such date is not a Business Day. At least 15
days before the special record date, the Company shall mail or cause to be
mailed to each Securityholder, with a copy to the Trustee, a notice that states
the special record date, the payment date, and the amount of defaulted interest,
and interest payable on such defaulted interest, if any, to be paid.

         Except as otherwise specified as contemplated by Section 2.2 for
Securities of any Series, interest on the Securities of each Series shall be
computed on the basis of a 360-day year of twelve 30-day months.

         2.14     CUSIP NUMBER.

         The Company in issuing the Securities may use one or more "CUSIP"
numbers, and if so, the Trustee shall use the CUSIP number(s) in notices of
redemption or exchange as a convenience to Holders, provided that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number(s) printed in the notice or on the Securities, and
that reliance may be placed only on the other identification numbers printed on
the Securities.

         2.15     PROVISIONS FOR GLOBAL SECURITIES.

                                    (a)      A Board Resolution, a supplemental
indenture hereto or an Officers' Certificate shall establish whether the
Securities of a Series shall be issued in whole or in part in the form of one or
more Global Securities and the Depositary for such Global Securities or
Securities.

                                    (b)      Notwithstanding any provisions to
the contrary contained in Section 2.7 of the Indenture and in addition thereto,
any Global Security shall be exchangeable pursuant to Section 2.7 of the

                                   REDEMPTION

         3.1      NOTICES OF TRUSTEE.

         The Company may, with respect to any Series of Securities, reserve the
right to redeem and pay the Series of Securities or may covenant to redeem and
pay the Series of Securities or any part thereof prior to the Stated Maturity
thereof at such time and on such terms as provided for in such Securities or the
related Board Resolution, supplemental indenture or Officers' Certificate. If a
Series of Securities is redeemable and the Company elects to redeem such
Securities of a Series, it shall notify the Trustee of the Redemption Date and
the principal amount of Securities to be redeemed at least 35 days (unless a
shorter notice shall be satisfactory to the Trustee) but not more than 60 days
before the Redemption Date. Any such notice may be canceled at any time prior to
notice of such redemption being mailed to any Holder and shall thereby be void
and of no effect.

         3.2      SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         Unless otherwise indicated for a particular Series of Securities by a
Board Resolution, a supplemental indenture or an Officers' Certificate, if fewer
than all of the Securities of a Series are to be redeemed, the Trustee shall
select the Securities of a Series to be redeemed pro rata, by

                                     - 16 -

<PAGE>

lot or by any other method that the Trustee considers fair and appropriate and,
if such Securities are listed on any securities exchange, by a method that
complies with the requirements of such exchange.

         The Trustee shall make the selection from Securities of a Series
outstanding and not previously called for redemption and shall promptly notify
the Company in writing of the Securities selected for redemption and, in the
case of any Security selected for partial redemption, the principal amount
thereof to be redeemed. Securities of a Series in denominations of $1,000 may be
redeemed only in whole. The Trustee may select for redemption portions of the
principal of Securities of a Series that have denominations larger than $1,000.
Securities of a Series and portions of them it selects shall be in amounts of
$1,000 or, with respect to Securities of any Series issuable in other
denominations pursuant to Section 2.2(10), the minimum principal denomination
for each Series and integral multiples thereof. Provisions of this Indenture
that apply to Securities called for redemption also apply to portions of
Securities called for redemption.

         3.3      NOTICE OF REDEMPTION.

         Unless otherwise indicated for a particular Series by Board Resolution,
a supplemental indenture hereto or an Officers' Certificate, at least 30 days,
and no more than 60 days, before a Redemption Date, the Company shall mail, or
cause to be mailed, a notice of redemption by first-class mail to each Holder of
Securities to be redeemed at his or her last address as the same appears on the
registry books maintained by the Registrar.

         The notice shall identify the Securities to be redeemed (including the
CUSIP number(s) thereof, if any) and shall state:

                  (1)      the Redemption Date;

                  (2)      the redemption price;

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

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

                  (5)      that Securities of a Series called for redemption
must be surrendered to the Paying Agent to collect the redemption price, and the
place or places where each such Security is to be surrendered for such payment;

                  (6)      that, unless the Company defaults in making the
redemption payment, interest on the Securities of a Series called for redemption
ceases to accrue on or after the Redemption Date, and the only remaining right
of the Holders of such Securities is to receive payment of the redemption price
upon surrender to the Paying Agent of the Securities redeemed; and

                                     - 17 -

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

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

         3.4      EFFECT OF NOTICE OF REDEMPTION.

         Once the notice of redemption described in Section 3.3 is mailed,
Securities of a Series called for redemption become due and payable on the
Redemption Date and at the redemption price, plus interest, if any, accrued to
(but not including) the Redemption Date. Upon surrender to the Trustee or Paying
Agent, such Securities of a Series shall be paid at the redemption price, plus
accrued interest, if any, to (but not including) the Redemption Date, provided
that if the Redemption Date is after a regular interest payment record date and
on or prior to the next Interest Payment Date, the accrued interest shall be
payable to the Holder of the redeemed Securities registered on the relevant
record date, as specified by the Company in the notice to the Trustee pursuant
to Section 3.1 hereof.

         3.5      DEPOSIT OF REDEMPTION PRICE.

         On or prior to the Redemption Date, the Company shall deposit with the
Paying Agent money sufficient to pay the redemption price of and accrued
interest, if any, on all Securities to be redeemed on that date other than
Securities or portions thereof called for redemption on that date which have
been delivered by the Company to the Trustee for cancellation.

         On and after any Redemption Date, if money sufficient to pay the
redemption price of and accrued interest on Securities called for redemption
shall have been made available in accordance with the preceding paragraph and
the Company and the Paying Agent are not prohibited from paying such moneys to
Holders, the Securities called for redemption will cease to accrue interest and
the only right of the Holders of such Securities will be to receive payment of
the redemption price of and, subject to the proviso in Section 3.4, accrued and
unpaid interest on such Securities to the Redemption Date. If any Security
called for redemption shall not be so paid, interest will be paid, from the
Redemption Date until such redemption payment is made, on the unpaid principal
of the Security and any interest or premium (if any) not paid on such unpaid
principal, in each case, at the rate and in the manner provided in the
Securities.

         3.6      SECURITIES REDEEMED IN PART.

         Upon surrender of a Security of a Series that is redeemed in part, the
Trustee shall authenticate for a Holder a new Security of the same Series equal
in principal amount to the unredeemed portion of the Security surrendered.

         The Company covenants (to the extent that it may lawfully do so) that
they will not at any time insist upon, or plead (as a defense or otherwise) or
in any manner whatsoever claim or take the benefit or advantage of, any stay,
extension law, usury law or other law which would prohibit or forgive the
Company from paying all or any portion of the principal of, premium, if any,
and/or interest on the Securities as contemplated herein, wherever enacted, now
or at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture; and (to the extent that they may lawfully do so)
the Company 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

if any, or interest that has become due solely because of the acceleration, have
been cured or waived, (ii) to the extent the payment of such interest is lawful,
interest on overdue installments of interest and overdue principal, which has
become due otherwise than by such declaration of acceleration, has been paid and
(iii) if the rescission would not conflict with any judgment or decree. No such
rescission shall affect any subsequent Default or impair any right consequent
thereto. In case an Event of Default specified in Section 6.1(6) or (7) with
respect to the Company occurs, such principal, premium, if any, and interest
amount with respect to all of the Securities of that Series shall be due and
payable immediately without any declaration or other act on the part of the
Trustee or the Holders of the Securities of that Series.

         6.3      OTHER REMEDIES.

         If an Event of Default with respect to Securities of any Series at the
time outstanding occurs and is continuing, the Trustee may pursue any available
remedy by proceeding at law or in equity to collect the payment of principal of,
or premium, if any, and interest on the Securities of that Series or to enforce
the performance of any provision of the Securities of that Series or this
Indenture.

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

         6.4      WAIVER OF PAST DEFAULTS AND EVENTS OF DEFAULT.

         Subject to Sections 6.2, 6.7 and 8.2 hereof, the Holders of a majority
in principal amount of the Securities of any Series then outstanding have the
right to waive any existing Default or Event of Default with respect to such
Series or compliance with any provision of this Indenture (with respect to such
Series) or the Securities of such Series. Upon any such waiver, such Default
with respect to such Series shall cease to exist, and any Event of Default with
respect to such Series 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 Event of Default or impair any right consequent
thereto.

         6.5      CONTROL BY MAJORITY.

         The Holders of a majority in principal amount of the Securities of any
Series then outstanding may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee by this Indenture with respect to such Series.
The Trustee, however, may refuse to follow any direction that conflicts with law
or this Indenture or that the Trustee determines may be unduly prejudicial to
the rights of another Securityholder or that may involve the Trustee in personal
liability; provided that the Trustee may take any other action deemed proper by
the Trustee which is not inconsistent with such direction.

         6.6      LIMITATION ON SUITS.

         Subject to Section 6.7 below, a Securityholder may not institute any
proceeding or pursue any remedy with respect to this Indenture or the Securities
of a Series unless:

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

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

                  (3)      such Holder or Holders offer to the Trustee indemnity
reasonably satisfactory to the Trustee against any loss, liability or expense to
be incurred in compliance with such request;

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

                  (5)      no direction inconsistent with such written request
has been given to the Trustee during such 60-day period by the Holders of a
majority in aggregate principal amount of the Securities of such Series then
outstanding.

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

         6.7      RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Security of a Series to receive payment of principal of, or premium,
if any, and interest of the Security of such Series on or after the respective
due dates expressed in the Security of such Series, or to bring suit for the
enforcement of any such payment on or after such respective dates, is absolute
and unconditional and shall not be impaired or affected without the consent of
the Holder.

         6.8      COLLECTION SUIT BY TRUSTEE.

         If an Event of Default in payment of principal, premium or interest
specified in Section 6.1(1) or (2) hereof with respect to Securities of any
Series at the time outstanding occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
(or any other obligor on the Securities of that Series) for the whole amount of
unpaid principal and accrued interest remaining unpaid, together with interest
on overdue principal and, to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate then
borne by the Securities of that Series, and such further amounts as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

         6.9      TRUSTEE MAY FILE PROOFS OF CLAIM.

         The Trustee may file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel) and the Securityholders
allowed in any judicial proceedings relative to the Company (or any other
obligor upon the Securities), any of their respective creditors or any of their
respective property and shall be entitled and empowered to collect and receive
any monies or other property payable or deliverable on any such claims and to
distribute the same after deduction of its charges and expenses to the extent
that any such charges and expenses are not paid out of the estate in any such
proceedings and any custodian in any such judicial proceeding is hereby
authorized by each Securityholder 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 Securityholders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section 7.7
hereof.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Securityholder any
plan or reorganization, arrangement, adjustment or composition affecting the
Securities of a Series or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Securityholder in any such
proceedings.

         6.10     PRIORITIES.

         If the Trustee collects any money pursuant to this Article 6, it shall
pay out the money in the following order:

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

         SECOND: to Securityholders for amounts then due and unpaid for
principal, premium, if any, and interest on the Securities 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
such Securities for principal and any premium and interest, respectively; and

                                     - 26 -

<PAGE>

         THIRD: to the Company.

         The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10.

         6.11     UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.7 hereof or a suit by Holders of more than 10% in
principal amount of the Securities of a Series then outstanding.

         7.1      DUTIES OF TRUSTEE.

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

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

                                             (1)      The Trustee need perform
only those duties that are specifically set forth in this Indenture and no
covenants or obligations shall be implied in this Indenture against the Trustee.

                                             (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.

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

                                             (1)      This paragraph does not
limit the effect of paragraph (b) of this Section 7.1.

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

                                             (3)      The Trustee shall not be

accordance with a direction received by it pursuant to Sections 6.2 and 6.5
hereof.

                                    (d)      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 rights or powers if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity satisfactory to it against such risk or liability is not
reasonably assured to it.

                                    (e)      Whether or not therein expressly so
provided, paragraphs (a), (b), (c) and (d) of this Section 7.1 shall govern
every provision of this Indenture that in any way relates to the Trustee.

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

         7.2      RIGHTS OF TRUSTEE.

                                    (a)      Subject to Section 7.1 hereof:

                                             (1)      The Trustee may rely on
and shall be protected in acting or refraining from acting upon any document
reasonably believed by it to be genuine and to have been signed or presented by
the proper person. The Trustee need not investigate any fact or matter stated in
the document.

                                             (2)      Before the Trustee acts or
refrains from acting, it may require an Officers' Certificate or an Opinion of
Counsel, or both, which shall conform to the provisions of Section 10.5 hereof.
The Trustee shall be protected and shall not be liable for any action it takes
or omits to take in good faith in reliance on such certificate or opinion.

                                             (3)      The Trustee may act
through agents and shall not be responsible for the misconduct or negligence of

<PAGE>

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

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

                                             (7)      The Trustee shall not be
deemed to have knowledge of any fact or matter unless such fact or matter is
known to a Responsible Officer of the Trustee.

         7.3      INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may make loans to, accept deposits from,
perform services for or otherwise deal with the Company, or any Affiliate
thereof, with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. The Trustee, however, shall be subject to
Sections 7.10 and 7.11 hereof.

         7.4      TRUSTEE'S DISCLAIMER.

         The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Securities (except that the Trustee represents that it is
duly authorized to execute and deliver this Indenture and authenticate the
Securities and perform its obligations hereunder), it shall not be accountable
for the Company's use of the proceeds from the sale of Securities or any money
paid to the Company pursuant to the terms of this Indenture and it shall not be
responsible for any statement in the Securities other than its certificates of
authentication.

         7.5      NOTICE OF DEFAULT.

         If a Default or an Event of Default occurs and is continuing with
respect to the Securities of any Series and if it is known to the Trustee, the
Trustee shall mail to each Securityholder of the Securities of that Series
notice of the Default or the Event of Default, as the case may be, within 30
days after it occurs. Except in the case of a Default or an Event of Default in
payment of the principal of, or premium, if any, or interest on any Security of
any Series, the Trustee may withhold the notice if and so long as the Board of
Directors of the Trustee, the executive committee or any trust committee of such
board and/or its Responsible Officers in good faith determine(s) that
withholding the notice is in the interests of the Securityholders of that
Series.

         7.6      REPORTS BY TRUSTEE TO HOLDERS.

         If and to the extent required by the TIA, within 60 days after May 15
of each year, commencing the May 15 following the date of this Indenture, the
Trustee shall mail to each

                                     - 29 -

<PAGE>

Securityholder a brief report dated as of such May 15 that complies with TIA
Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and
313(c).

         A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and any stock exchange on which the Securities of
that Series are listed. The Company shall promptly notify the Trustee when the
Securities of any Series are listed on any stock exchange, and the Trustee shall
comply with TIA Section 313(d).

         7.7      COMPENSATION AND INDEMNITY.

         The Company shall pay to the Trustee from time to time reasonable
compensation for its services. The Trustee's compensation shall not be limited
by any provision of law on compensation of a trustee of an express trust. The
Company shall reimburse the Trustee upon request for all reasonable
disbursements, expenses and advances incurred or made by it in connection with
its duties under this Indenture, including the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel.

         The Company shall indemnify the Trustee for, and hold it harmless
against, any and all loss or liability incurred by it in connection with the
acceptance or performance of its duties under this Indenture including the
reasonable 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. The Trustee shall notify the Company promptly of any claim asserted
against the Trustee for which it may seek indemnity. However, the failure by the
Trustee to so notify the Company shall not relieve the Company of its
obligations. Notwithstanding the foregoing, the Company need not reimburse the
Trustee for any expense or indemnify it against any loss or liability incurred
by the Trustee through its negligence or bad faith.

         To secure the payment obligations of the Company in this Section 7.7,
the Trustee shall have a Lien prior to the Securities of any Series on all money
or property held or collected by the Trustee, except such money or property held
in trust to pay principal of and interest and premium (if any) on particular
Securities of that Series.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(6) or (7) hereof occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

         For purposes of this Section 7.7, the term "Trustee" shall include any
trustee appointed pursuant to Article 9.

         7.8      REPLACEMENT OF TRUSTEE.

         The Trustee may resign with respect to the Securities of one or more
Series by so notifying the Company in writing at least 90 days in advance of
such resignation.

         The Holders of a majority in principal amount of the outstanding
Securities of any Series may remove the Trustee with respect to that Series by
notifying the removed Trustee in writing and may appoint a successor Trustee
with respect to that Series with the written consent of the

                                     - 30 -

<PAGE>

Company, which consent shall not be unreasonably withheld. The Company may
remove the Trustee with respect to that Series at its election if:

                  (1)      the Trustee fails to comply with, or ceases to be
eligible under, Section 7.10 hereof;

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

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

                  (4)      the Trustee otherwise becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee with respect to any Series of Securities for any reason, the
Company shall promptly notify each Holder of such event and shall promptly
appoint a successor Trustee.

         If a successor Trustee with respect to the Securities of one or more
Series does not take office within 60 days after the retiring Trustee resigns or
is removed, the retiring Trustee, the Company or the Holders of at least 10% in
principal amount of the outstanding Securities of the applicable Series may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

         If the Trustee with respect to the Securities of one or more Series
fails to comply with Section 7.10 hereof, any Securityholder of the applicable
Series may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately following
such delivery (i) the retiring Trustee with respect to one or more Series shall,
subject to its rights under Section 7.7 hereof, transfer all property held by it
as Trustee with respect to such Series to the successor Trustee, (ii) the
resignation or removal of the retiring Trustee shall become effective, and (iii)
the successor Trustee with respect to such Series shall have all the rights,
powers and duties of the Trustee under this Indenture. A successor Trustee with
respect to the Securities of one or more Series shall mail notice of its
succession to each Securityholder of such Series.

         7.9      SUCCESSOR TRUSTEE BY CONSOLIDATION, MERGER OR CONVERSION.

         If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all of its corporate trust assets to, another corporation,
subject to Section 7.10 hereof, the successor corporation without any further
act shall be the successor Trustee.

         7.10     ELIGIBILITY; DISQUALIFICATION.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Sections 310(a)(1), (2) and (5) in every respect. The
Trustee shall have a combined capital and surplus of at least $100,000,000 as
set forth in its most recent published annual report of

                                     - 31 -

<PAGE>

condition. The Trustee shall comply with TIA Section 310(b), including the
provision in Section 310(b)(1). If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 7.10, it shall resign
immediately in the manner and with the effect specified in this Article 7.

         7.11     PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         The Trustee shall comply with TIA Section 311(a), excluding any

therein.

         7.12     PAYING AGENTS.

         The Company shall cause each Paying Agent other than the Trustee to
execute and deliver to it and the Trustee an instrument in which such agent
shall agree with the Trustee, subject to the provisions of this Section 7.12:

                  (1)      that it will hold all sums held by it as agent for
the payment of principal of, or premium, if any, or interest on, the Securities
(whether such sums have been paid to it by the Company or by any obligor on the
Securities) in trust for the benefit of Holders of the Securities or the
Trustee;

                  (2)      that it will at any time during the continuance of
any Event of Default, upon written request from the Trustee, deliver to the
Trustee all sums so held in trust by it together with a full accounting thereof;
and

                  (3)      that it will give the Trustee written notice within
three (3) Business Days of any failure of the Company (or by any obligor on the
Securities) in the payment of any installment of the principal of, premium, if
any, or interest on, the Securities when the same shall be due and payable.

appointment hereunder by a successor Trustee with respect to the Securities of
one or more Series and to add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee.

                  The Trustee is hereby authorized to join with the Company in
the execution of any supplemental indenture authorized or permitted by the terms
of this Indenture and to make any further appropriate agreements and
stipulations which may be therein contained, but the Trustee shall not be
obligated to enter into any such supplemental indenture which adversely affects
its own rights, duties or immunities under this Indenture.

         8.2      WITH CONSENT OF HOLDERS.

                                    (a)      The Company, when authorized by a
Board Resolution, and the Trustee may amend or supplement this Indenture or the
Securities of one or more Series with the written consent of the Holders of not
less than a majority in aggregate principal amount of the outstanding Securities
of such Series affected by such amendment or supplement without notice to any
Securityholder. The Holders of not less than a majority in aggregate principal
amount of the outstanding Securities of each such Series affected by such
amendment or supplement may waive compliance in a particular instance by the
Company with any provision of this Indenture or the Securities of such Series
without notice to any Securityholder. Subject to Section 8.4, without the
consent of each Securityholder affected, however, an amendment, supplement or
waiver, including a waiver pursuant to Section 6.4, may not:

                                             (1)      reduce the amount of
Securities whose Holders must consent to an amendment, supplement or waiver to
this Indenture or the Securities;

                                             (2)      reduce the rate of or
change the time for payment of interest on any Security;

                                             (3)      reduce the principal or
change the Stated Maturity of any Security or reduce the amount of, or postpone
the date fixed for, the payment of any sinking fund or analogous obligation;

                                             (4)      make any Security payable
in money other than that stated in the Security;

                                             (5)      change the amount or time
of any payment required by the Securities or reduce the premium payable upon any
redemption of the Securities, or change the time before which no such redemption
may be made;

                                     - 33 -

<PAGE>

                                             (6)      waive a Default or Event
of Default in the payment of the principal of or interest or premium, if any, on
any Security (except a rescission of acceleration of the Securities of any
Series by the Holders of at least a majority in principal amount of the
outstanding Securities of such Series and a waiver of the payment default that
resulted from such acceleration);

                                             (7)      waive a redemption payment
with respect to any Security or change any of the provisions with respect to the
redemption of any Securities;

                                             (8)      make any changes in
Sections 6.4 or 6.7 hereof or this Section 8.2, except to increase any
percentage of Securities the Holders of which must consent to any matter; or; or

                                             (9)      take any other action
otherwise prohibited by this Indenture to be taken without the consent of each
holder affected thereby.

                                    (b)      Upon the request of the Company,
accompanied by a Board Resolution authorizing the execution of any such
supplemental indenture, and upon the receipt by the Trustee of evidence
reasonably satisfactory to the Trustee of the consent of the Securityholders as
aforesaid and upon receipt by the Trustee of the documents described in Section
8.6 hereof, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture, in which case the Trustee
may in its discretion, but shall not be obligated to, enter into such
supplemental indenture.

                                    (c)      It shall not be necessary for the
consent of the Holders under this section to approve the particular form of any
proposed amendment, supplement or waiver, but it shall be sufficient if such
consent approves the substance thereof.

         8.3      COMPLIANCE WITH TRUST INDENTURE ACT.

         Every amendment to or supplement of this Indenture or the Securities
shall comply with the TIA as then in effect.

         8.4      REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment, supplement, waiver or other action becomes
effective, a consent to it by a Holder of a Security is a continuing consent
conclusive and binding upon such Holder and every subsequent Holder of the same
Security or portion thereof, and of any Security issued upon the transfer
thereof or in exchange therefor or in place thereof, even if notation of the
consent is not made on any such Security. Any such Holder or subsequent Holder,
however, may revoke the consent as to his Security or portion of a Security, if
the Trustee receives the notice of revocation before the date the amendment,
supplement, waiver or other action becomes effective.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement, or waiver which record date shall be at least 30 days prior to the
first solicitation of such consent. If a record date is fixed, then,
notwithstanding the preceding paragraph, those Persons who were Holders at such

                                     - 34 -

<PAGE>

record date (or their duly designated proxies), and only such Persons, shall be
entitled to consent to such amendment, supplement, or waiver or to revoke any
consent previously given, whether or not such Persons continue to be Holders
after such record date. No such consent shall be valid or effective for more
than 90 days after such record date without the applicable amendment, supplement
or waiver becoming effective.

         After an amendment, supplement, waiver or other action becomes
effective, it shall bind every Securityholder, unless it makes a change
described in any of clauses (1) through (9) of Section 8.2 hereof. In that case
the amendment, supplement, waiver or other action shall bind each Holder of a
Security who has consented to it and every subsequent Holder of a Security or
portion of a Security that evidences the same debt as the consenting Holder's
Security; provided that any such waiver shall not impair or affect the right of
any Holder to receive payment of principal of and interest and premium (if any)
on a Security, on or after the respective due dates expressed in such Security,
or to bring suit for the enforcement of any such payment on or after such
respective dates without the consent of such Holder.

         8.5      NOTATION ON OR EXCHANGE OF SECURITIES.

         If an amendment, supplement, or waiver changes the terms of a Security
of any Series, the Trustee may request the Holder of such Security to deliver it
to the Trustee. In such case, the Trustee shall place an appropriate notation on
such Security about the changed terms and return it to the Holder.
Alternatively, if the Company or the Trustee so determines, the Company in
exchange for such Security shall issue and the Trustee shall authenticate a new
security that reflects the changed terms. Failure to make the appropriate
notation or issue a new Security shall not affect the validity and effect of
such amendment, supplement or waiver.

         8.6      TRUSTEE TO SIGN AMENDMENTS, ETC.

         The Trustee shall sign any amendment, supplement or waiver authorized
pursuant to this Article 8 if the amendment, supplement or waiver does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may, but need not, sign it. In signing or refusing to
sign such amendment, supplement or waiver the Trustee shall be entitled to
receive and, subject to Section 7.1 hereof, shall be fully protected in relying
upon an Officers' Certificate and an Opinion of Counsel stating that such
amendment, supplement or waiver is authorized or permitted by this Indenture.
The Company may not sign an amendment or supplement until the Board of Directors
of the Company approves it.

                                    ARTICLE 9
                       DISCHARGE OF INDENTURE; DEFEASANCE

         9.1      DISCHARGE OF INDENTURE.

         The Company may terminate its obligations under the Securities of any
Series and this Indenture with respect to such Series, except the obligations
referred to in the last paragraph of this Section 9.1, if there shall have been
canceled by the Trustee or delivered to the Trustee for cancellation all
Securities of such Series theretofore authenticated and delivered (other than
any Securities of such Series that are asserted to have been destroyed, lost or
stolen and that shall

                                     - 35 -

<PAGE>

have been replaced as provided in Section 2.8 hereof) and the Company has paid
all sums payable by it hereunder or deposited all required sums with the
Trustee.

         After such delivery the Trustee upon request shall acknowledge in
writing the discharge of the Company's obligations under the Securities of such
Series and this Indenture except for those surviving obligations specified
below.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company in Sections 7.7, 9.5 and 9.6 hereof shall survive.

         9.2      LEGAL DEFEASANCE.

         The Company may at its option, by Board Resolution, be discharged from
its obligations with respect to the Securities of any Series on the date the
conditions set forth in Section 9.4 below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, such Legal Defeasance means that the Company
shall be deemed to have paid and discharged the entire indebtedness represented
by the Securities of such Series and to have satisfied all its other obligations
under such Securities and this Indenture insofar as such Securities are
concerned (and the Trustee, at the expense of the Company, shall, subject to
Section 9.6 hereof, execute proper instruments acknowledging the same), except
for the following which shall survive until otherwise terminated or discharged
hereunder: (A) the rights of Holders of outstanding Securities of such Series to
receive solely from the trust funds described in Section 9.4 hereof and as more
fully set forth in such section, payments in respect of the principal of,
premium, if any, and interest on the Securities of such Series when such
payments are due, (B) the Company's obligations with respect to the Securities
of such Series under Sections 2.4, 2.5, 2.6, 2.7, 2.8 and 2.9 hereof, (C) the
rights, powers, trusts, duties, and immunities of the Trustee hereunder
(including claims of, or payments to, the Trustee under or pursuant to Section
7.7 hereof) and (D) this Article 9. Subject to compliance with this Article 9,
the Company may exercise its option under this Section 9.2 with respect to the
Securities of any Series notwithstanding the prior exercise of its option under
Section 9.3 below with respect to the Securities of such Series.

         9.3      COVENANT DEFEASANCE.

         At the option of the Company, pursuant to a Board Resolution, the
Company shall be released from its obligations under Sections 4.2 through 4.7
hereof, inclusive, and Section 5.1 hereof, with respect to the outstanding
Securities of any Series, on and after the date the conditions set forth in
Section 9.4 hereof are satisfied (hereinafter, "Covenant Defeasance"). For this
purpose, such Covenant Defeasance means that the Company may omit to comply with
and shall have no liability in respect of any term, condition or limitation set
forth in any such specified section or portion thereof, whether directly or
indirectly by reason of any reference elsewhere herein to any such specified
Section or portion thereof or by reason of any reference in any such specified
section or portion thereof to any other provision herein or in any other
document, but the remainder of this Indenture and the Securities of any Series
shall be unaffected thereby.

of making the following payments, specifically pledged as security for, and
dedicated solely to, the benefit of the Holders of the Securities, (A) money in
an amount, or (B) U.S. Government Obligations or Foreign Government Obligations

opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge, and which shall be applied by the Trustee (or other qualifying

period ending on the 91st day after the date of such deposit or, if longer,
ending on the day following the expiration of the longest preference period
under any Bankruptcy Law applicable to the Company in respect of such deposit
(it being understood that this condition shall not be deemed satisfied until the
expiration of such period);

                  (3)      such Legal Defeasance or Covenant Defeasance shall
not cause the Trustee to have a conflicting interest for purposes of the TIA
with respect to any securities of the Company;

                  (4)      such Legal Defeasance or Covenant Defeasance shall
not result in a breach or violation of, or constitute default under any other

amended;

                  (6)      in the case of an election under Section 9.2 above,

<PAGE>

solely as a result of such Legal Defeasance and will be subject to Federal
income tax on the same amounts, in the same manner, including as a result of
prepayment, and at the same times as would have been the case if such Legal
Defeasance had not occurred;

                  (7)      in the case of an election under Section 9.3 hereof,
the Company shall have delivered to the Trustee an Opinion of Counsel to the
effect that the Holders of the outstanding Securities of such Series will not

such Covenant Defeasance and will be subject to Federal income tax on the same

payment under terms mutually satisfactory to the Company and the Trustee all
amounts then due to the Trustee pursuant to Section 7.7 hereof.

         9.5      DEPOSITED MONEY AND U.S. AND FOREIGN GOVERNMENT OBLIGATIONS TO
BE HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

         All money, U.S. Government Obligations and Foreign Government
Obligations (including the proceeds thereof) deposited with the Trustee pursuant
to Section 9.4 hereof in respect of the outstanding Securities shall be held in
trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any
Paying Agent as the Trustee may determine, to the Holders of such Securities, of
all sums due and to become due thereon in respect of principal, premium, if any,
and accrued interest, but such money need not be segregated from other funds
except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations and
Foreign Government Obligations deposited pursuant to Section 9.4 hereof or the
principal, premium, if any, and interest received in respect thereof other than
any such tax, fee or other charge which by law is for the account of the Holders
of the outstanding Securities.

         Anything in this Article 9 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money, U.S. Government Obligations or Foreign Government Obligations held by it
as provided in Section 9.4 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount

                                     - 38 -

<PAGE>

thereof which would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance.

         9.6      REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any money, U.S.
Government Obligations or Foreign Government Obligations in accordance with
Section 9.1, 9.2, 9.3 or 9.4 hereof by reason of any legal proceeding or by
reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to this Article 9 until
such time as the Trustee or Paying Agent is permitted to apply all such money,
U.S. Government Obligations or Foreign Government Obligations, as the case may
be, in accordance with Section 9.1, 9.2, 9.3 or 9.4 hereof; provided, however,
that if the Company has made any payment of principal of, premium, if any, or
accrued interest on any Securities because of the reinstatement of their
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money, U.S. Government
Obligations or Foreign Government Obligations held by the Trustee or Paying
Agent.

         9.7      MONEYS HELD BY PAYING AGENT.

         In connection with the satisfaction and discharge of this Indenture,
all moneys then held by any Paying Agent under the provisions of this Indenture
shall, upon demand of the Company, be paid to the Trustee, or if sufficient
moneys have been deposited pursuant to Section 9.1 hereof, to the Company, and
thereupon such Paying Agent shall be released from all further liability with
respect to such moneys.

         9.8      MONEYS HELD BY TRUSTEE.

         Any moneys deposited with the Trustee or any Paying Agent or then held
by the Company in trust for the payment of the principal of, or premium, if any,
or interest on any Security that are not applied but remain unclaimed by the
Holder of such Security for two years after the date upon which the principal
of, or premium, if any, or interest on such Security shall have respectively
become due and payable shall be repaid to the Company upon Company Request, or
if such moneys are then held by the Company in trust, such moneys shall be
released from such trust; and the Holder of such Security entitled to receive
such payment shall thereafter, as an unsecured general creditor, look only to
the Company for the payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money shall thereupon cease; provided,
however, that the Trustee or any such Paying Agent, before being required to
make any such repayment, may, at the expense of the Company, either mail to each
Securityholder affected, at the address shown in the register of the Securities
maintained by the Registrar or cause to be published once a week for two
successive weeks, in a newspaper published in the English language, customarily
published each Business Day and of general circulation in the City of New York,
New York, a 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
mailing or publication, any unclaimed balance of such moneys then remaining will
be repaid to the Company. After payment to the Company or the release of any
money held in trust by the

                                     - 39 -

Company, Securityholders entitled to the money must look only to the Company for
payment as general creditors unless applicable abandoned property law designates
another person.

         10.6     RULES BY TRUSTEE AND AGENTS.

         10.7     BUSINESS DAYS; LEGAL HOLIDAYS.

         A "Business Day" is a day that is not a Legal Holiday. A "Legal
Holiday" is a Saturday, a Sunday, a federally recognized holiday or a day on
which banking institutions are not required to be open in the State of New York
or the Commonwealth of Kentucky.

         If a payment date is a Legal Holiday at a place of payment, payment may
be made at that place on the next succeeding day that is not a Legal Holiday,
and no interest shall accrue for the intervening period.

         10.8     GOVERNING LAW.

         THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE
AND PERFORMED WITHIN THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF
CONFLICTS OF LAW. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE
JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR PROCEEDING
ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE SECURITIES.

         10.9     NO ADVERSE INTERPRETATION OF OTHER AGREEMENTS.

         This Indenture may not be used to interpret another indenture, loan,
security or debt agreement of the Company or any Subsidiary thereof. No such
indenture, loan, security or debt agreement may be used to interpret this
Indenture.

         10.10    NO RECOURSE AGAINST OTHERS.

         A director, officer, employee, stockholder or incorporator, as such, of
the Company shall not have any liability for any obligations of the Company
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creations. Each Securityholder by
accepting a Security waives and releases all such liability. Such waiver and
release are part of the consideration for the issuance of the Securities.

         10.11    SUCCESSORS AND ASSIGNS.

         All agreements of the Company in this Indenture and the Securities
shall bind its successors and assigns, whether so expressed or not. All
agreements of the Trustee, any additional trustee and any Paying Agents in this
Indenture shall bind their respective successors and assigns.

         10.12    MULTIPLE COUNTERPARTS.

         The parties may sign multiple counterparts of this Indenture. Each
signed counterpart shall be deemed an original, but all of them together
represent one and the same agreement.

         10.13    TABLE OF CONTENTS, HEADINGS, ETC.

         The table of contents, cross-reference sheet and headings of the
Articles and Sections of this Indenture have been inserted for convenience of
reference only, are not to be considered a part hereof, and shall in no way
modify or restrict any of the terms or provisions hereof.

         10.14    SEPARABILTY.

         Each provision of this Indenture shall be considered separable and if
for any reason any provision which is not essential to the effectuation of the
basic purpose of this Indenture or the Securities shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

         10.15    SECURITIES IN A FOREIGN CURRENCY OR IN ECU.

         Unless otherwise specified in a Board Resolution, a supplemental
indenture hereto or an Officers' Certificate delivered pursuant to Section 2.2
of this Indenture with respect to a particular Series of Securities, whenever
for purposes of this Indenture any action may be taken by the Holders of a
specified percentage in aggregate principal amount of Securities of all Series
or all Series affected by a particular action at the time outstanding and, at
such time, there are outstanding Securities of any Series which are denominated
in a coin or currency other than Dollars (including ECU), then the principal
amount of Securities of such Series which shall be deemed to be outstanding for
the purpose of taking such action shall be that amount of Dollars that could be
obtained for such amount at the Market Exchange Rate at such time. For purposes
of this Section 10.16, "Market Exchange Rate" shall mean the noon Dollar buying
rate in New York City for cable transfers of that currency as published by the
Federal Reserve Bank of New York; provided, however, in the case of ECUs, Market
Exchange Rate shall mean the rate of exchange determined by the Commission of
the European Union (or any successor thereto) as

                                     - 43 -

<PAGE>

published in the Official Journal of the European Union (such publication or any
successor publication, the "Journal"). If such Market Exchange Rate is not
available for any reason with respect to such currency, the Trustee shall use,
in its sole discretion and without liability on its part, such quotation of the
Federal Reserve Bank of New York or, in the case of ECUs, the rate of exchange
as published in the Journal, as of the most recent available date, or quotations
or, in the case of ECUs, rates of exchange from one or more major banks in The
City of New York or in the country of issue of the currency in question or, in
the case of ECUs, in Luxembourg or such other quotations or, in the case of
ECUs, rates of exchange as the Trustee, upon consultation with the Company,
shall deem appropriate. The provisions of this paragraph shall apply in
determining the equivalent principal amount in respect of Securities of a Series
denominated in currency other than Dollars in connection with any action taken
by Holders of Securities pursuant to the terms of this Indenture.

         All decisions and determinations of the Trustee regarding the Market
Exchange Rate or any alternative determination provided for in the preceding
paragraph shall be in its sole discretion and shall, in the absence of manifest
error, be conclusive to the extent permitted by law for all purposes and
irrevocably binding upon the Company and all Holders.

         10.16    JUDGMENT CURRENCY.

         The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of or
interest or premium (if any) or other amount on the Securities of any Series
(the "Required Currency") into a currency in which a judgment will be rendered
(the "Judgment Currency"), the rate of exchange used shall be the rate at which
in accordance with normal banking procedures the Trustee could purchase in The
City of New York the Required Currency with the Judgment Currency on the day on
which final unappealable judgment is entered, unless such day is not a New York
Banking Day, then, the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City
of New York the Required Currency with the Judgment Currency on the New York
Banking Day preceding the day on which final unappealable judgment is entered
and (b) its obligations under this Indenture to make payments in the Required
Currency (i) shall not be discharged or satisfied by any tender, any recovery
pursuant to any judgment (whether or not entered in accordance with subsection
(a)), in any currency other than the Required Currency, except to the extent
that such tender or recovery shall result in the actual receipt, by the payee,
of the full amount of the Required Currency expressed to be payable in respect
of such payments, (ii) shall be enforceable as an alternative or additional
cause of action for the purpose of recovering in the Required Currency the
amount, if any, by which such actual receipt shall fall short of the full amount
of the Required Currency so expressed to be payable, and (iii) shall not be
affected by judgment being obtained for any other sum due under this Indenture.
For purposes of the foregoing, "New York Banking Day" means any day except a
Saturday, Sunday or a legal holiday in The City of New York on which banking
institutions are authorized or required by law, regulation or executive order to
close.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.
