interest at the rate of % per annum which will accrue from the date of such
demand for payment to the date payment of such interest has been made or duly
provided for, and such interest will also be payable on demand."]

applicable, insert: "any such"] interest on this Security will be made at the
office or agency of the Company maintained for the purpose in

            (c) All Securities of any one series will be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to below and (subject to Section 2.04) set
forth or determined in the manner provided in the Officer's Certificate referred
to above or in any such indenture supplemental hereto.

            (d) If any of the terms of the series are established by action
taken pursuant to a Board Resolution, a copy of an appropriate record of such

Company and delivered to the Trustee concurrently with or prior to the delivery

            (a) The Securities of each series will be in substantially the form
set forth in or otherwise contemplated by the recitals to this Indenture, with
appropriate variations to reflect the specific terms of such series. If the form
of Securities of any series is established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action will be certified by

Trustee concurrently with or prior to the delivery of the Company Order
contemplated by Section 2.04 for the authentication and delivery of such
Securities.

<PAGE>

SECTION 2.03. DATE AND DENOMINATIONS.

            Each Security will be dated the date of its authentication. The
Securities of each series will be issuable only in registered form without
coupons in such denominations as may be specified as contemplated by Section
2.01. In the absence of any such specified denomination with respect to the
Securities of any series, the Securities of such series will be issuable in
denominations of $1,000 and integral multiples thereof.

SECTION 2.04. EXECUTION, AUTHENTICATION AND DELIVERY OF SECURITIES.

            (a) The Securities will be executed on behalf of the Company by the
Chairman or any Vice Chairman of the Board of Directors, the Chief Executive
Officer, the President, or any Vice President of the Company and attested by the
Treasurer, the Secretary, any Assistant Treasurer, or any Assistant Secretary of
the Company under its corporate seal. The signature of any of these officers on
the Securities may be manual or facsimile. The seal of the Company may be in the
form of a facsimile thereof and may be impressed, affixed, imprinted, or
otherwise reproduced on the Securities.

            (b) Only such Securities bearing the Trustee's certificate of
authentication, signed manually by the Trustee, will be entitled to the benefits
of this Indenture or be valid or obligatory for any purpose. Such execution of
the certificate of authentication by the Trustee upon any Securities executed by
the Company will be conclusive evidence that the Securities so authenticated
have been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 2.08, for all
purposes of this Indenture such Security will be deemed never to have been
authenticated and delivered hereunder and will never be entitled to the benefits
of this Indenture.

            (c) Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company will bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

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

                                       20

<PAGE>

established by or pursuant to a Board Resolution as permitted by Section 2.02,
that such form has been established in conformity with the provisions of this
Indenture, and (iii) that such Securities, when authenticated and delivered by
the Trustee and issued by the Company in the manner and subject to any
conditions specified in such Opinion of Counsel, will constitute valid and
binding obligations of the Company enforceable in accordance with their terms,
except as the enforceability thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium, or other laws relating to or affecting creditors'
rights and by general principles of equity.

            (e) Notwithstanding the provisions of Sections 2.01 and 2.04(d), if
all Securities of a series are not to be originally issued at one time, it will
not be necessary to deliver the Officer's Certificate otherwise required
pursuant to Section 2.01 or the Company Order and Opinion of Counsel otherwise
required pursuant to Section 2.04(d) at or prior to the time of authentication
of each Security of such series if such documents are delivered at or prior to
the authentication upon original issuance of the first Security of such series
to be issued.

SECTION 2.05. REGISTRATION OF TRANSFER AND EXCHANGE.

            (a) The Company will cause to be kept at the Corporate Trust Office
a register (the register maintained in such office and in any other office or
agency of the Company in a Place of Payment being herein sometimes collectively
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company will provide for the registration
of Securities and of transfers of Securities. The Trustee is hereby appointed
"Security Registrar" for the purpose of registering Securities and transfers of
Securities as herein provided.

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

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

            (d) Every Security presented or surrendered for registration of
transfer or exchange will (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument or instruments of transfer,
in form reasonably satisfactory to the Company and the Security Registrar duly
executed, by the Holder thereof or his attorney duly authorized in writing. No
service charge will 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 2.06, 3.05, or 10.06 not

                                       21

<PAGE>

involving any transfer. The Company will not be required (i) to issue, register
the transfer of, or exchange Securities of any series during a period beginning
at the opening of business 15 calendar days before the mailing of a notice of
redemption of Securities of that series selected for redemption under Section
3.02(c) and ending at the close of business on the day of such mailing or (ii)
to register the transfer of or exchange any Security so selected for redemption
in whole or in part, except, in the case of any Securities to be redeemed in
part, the portion thereof not being redeemed.

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

            (f) Notwithstanding any other provision in this Indenture, no Global
Security may be transferred to, or registered or exchanged for Securities
registered in the name of, any Person other than the Depositary for such Global
Security or any nominee thereof, and no such transfer may be registered, unless
(i) such Depositary (A) notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security or (B) ceases to be a clearing
agency registered under the Exchange Act, (ii) the Company executes and delivers
to the Trustee a Company Order that such Global Security shall be so
transferable, registrable, and exchangeable, and such transfers shall be
registrable, (iii) there shall have occurred and be continuing an Event of
Default with respect to the Securities evidenced by such Global Security, or
(iv) there shall exist such other circumstances, if any, as have been specified
for this purpose as contemplated by Section 2.01. Notwithstanding any other
provision in this Indenture, a Global Security to which the restriction set
forth in the preceding sentence shall have ceased to apply may be transferred
only to, and may be registered and exchanged for Securities registered only in
the name or names of, such Person or Persons as the Depositary for such Global
Security shall have directed and no transfer thereof other than such a transfer
may be registered. Every Security authenticated and delivered upon registration
of transfer of, or in exchange for or in lieu of, a Global Security to which the
restriction set forth in the first sentence of this Section 2.05(f) shall apply,
whether pursuant to this Section 2.05, Section 2.06, 2.07, 3.05, or 10.06 or
otherwise, will be authenticated and delivered in the form of, and will be, a
Global Security.

SECTION 2.06. TEMPORARY SECURITIES.

            Pending the preparation of definitive Securities of any series, the
Company may execute and register, and upon Company Order the Trustee will
authenticate and deliver, temporary Securities (printed, lithographed, or
typewritten) of any authorized denomination, and substantially in the form of
the definitive Securities but with such omissions, insertions, and variations as
may be appropriate for temporary Securities, all as may be determined by the
officers of the Company executing such Securities as evidenced by their
execution of such Securities; PROVIDED, HOWEVER, that the Company will use
reasonable efforts to have definitive Securities of that series available at the
times of any issuance of Securities under this Indenture. Every temporary
Security will be executed and registered by the Company and be authenticated by
the Trustee upon the same conditions and in substantially the same manner, and
with like effect, as the definitive Securities. The Company will execute and
register and furnish definitive Securities

                                       22

<PAGE>

of such series as soon as practicable and thereupon any or all temporary
Securities of such series may be surrendered in exchange therefor at the office
or agency of the Company in the Place of Payment for that series, and the
Trustee will authenticate and deliver in exchange for such temporary Securities
of such series one or more definitive Securities of the same series, of any
authorized denominations, and of a like aggregate principal amount and tenor.
Such exchange will be made by the Company at its own expense and without any
charge to the Holder therefor. Until so exchanged, the temporary Securities of
any series authenticated and delivered hereunder will be entitled to the same
benefits under this Indenture as definitive Securities of the same series
authenticated and delivered hereunder.

SECTION 2.07. MUTILATED, DESTROYED, LOST, AND STOLEN SECURITIES.

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

            (b) If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss, or theft of any
Security and (ii) such security or indemnity as may be required by them to save
each of them 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 will execute and the Trustee will authenticate
and deliver, in lieu of any such destroyed, lost, or stolen Security, a new
Security of the same series and of like tenor and principal amount and bearing a
number not contemporaneously outstanding.

            (c) 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.

            (d) Upon the issuance of any new Security under this Section 2.07,
the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

            (e) Every new Security of any series issued pursuant to this Section
2.07 in exchange for any mutilated Security or in lieu of any destroyed, lost,
or stolen Security will constitute an original additional contractual obligation
of the Company, whether or not the mutilated, destroyed, lost, or stolen
Security shall be at any time enforceable by anyone, and will be entitled to all
the benefits of this Indenture equally and proportionately with any and all
other Securities of that series duly issued hereunder.

            (f) The provisions of this Section 2.07 are exclusive and will
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost, or stolen Securities.

                                       23

SECTION 2.08. CANCELLATION OF SURRENDERED SECURITIES.

            All Securities surrendered for payment, redemption, registration of
transfer or exchange, or for credit against any sinking fund payment will, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and will be promptly cancelled by it. 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, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered will be promptly
cancelled by the Trustee. No Securities will be authenticated in lieu of or in
exchange for any Securities cancelled as provided in this Section 2.08, except
as expressly permitted by this Indenture. The Trustee shall destroy all
cancelled Securities held by the Trustee and shall send a certificate of such
destruction to the Company.

SECTION 2.09. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

            (a) Except as otherwise provided as contemplated by Section 2.01
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 will 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.

            (b) Any interest on any Security of any series which is payable, but
is not punctually paid or duly provided for, on any Interest Payment Date
(herein called "Defaulted Interest") will forthwith cease to be payable to the
Holder on the relevant regular Record Date by virtue of having been such Holder,
and such Defaulted Interest may be paid by the Company together with interest
thereon (to the extent permitted by law) at the rate of interest applicable to
such Security, at its election in each case, as provided in clause (i) or (ii)
below:

                  (i) The Company may elect to make payment of any Defaulted
      Interest (and interest thereon, if any) to the Persons in whose names the
      Securities of such series (or their respective Predecessor Securities) are
      registered at the close of business on a Special Record Date for the
      payment of such Defaulted Interest, which will be fixed in the following
      manner. The Company will notify the Trustee in writing of the amount of
      Defaulted Interest (and interest thereon, if any) proposed to be paid on
      each Security of such series and the date of the proposed payment, and at
      the same time the Company will deposit with the Trustee an amount of money
      equal to the aggregate amount proposed to be paid in respect of such
      Defaulted Interest (and interest thereon, if any) or will 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
      (and interest thereon, if any) as in this clause (i) provided. Thereupon
      the Trustee will fix a Special Record Date for the payment of such
      Defaulted Interest (and interest thereon, if any) which will be not more
      than 15 calendar days and not less than 10 calendar days prior to the date
      of the proposed payment and not less than 10 calendar days after the
      receipt by the Trustee of the notice of the proposed payment. The Trustee
      will promptly notify the Company of such Special Record Date

                                       24

<PAGE>

      and, in the name and at the expense of the Company, will 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 of such series at his address as it appears in the Security
      Register, not less than 10 calendar days prior to such Special Record
      Date. Notice of the proposed payment of such Defaulted Interest (and
      interest thereon, if any) and the Special Record Date therefor having been
      so mailed, such Defaulted Interest will be paid to the Persons in whose
      names the Securities of such series (or their respective Predecessor
      Securities) are registered at the close of business on such Special Record
      Date and will no longer be payable pursuant to the following clause (ii).

                  (ii) The Company may make payment of any Defaulted Interest
      (and interest thereon, if any) on the Securities of any series 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
      (ii), such manner of payment shall be deemed practicable by the Trustee.

            (c) Subject to the foregoing provisions of this Section 2.09, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security will carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 2.10. 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 owner of such
Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 2.09) any interest on such Security and for all other
purposes whatsoever, whether or not such Security shall be overdue, and neither
the Company, the Trustee nor any agent of the Company or the Trustee will be
affected by notice to the contrary.

SECTION 2.11. COMPUTATION OF INTEREST.

            Except as otherwise specified as contemplated by Section 2.01 for
Securities of any series, interest on the Securities of each series will be
computed on the basis of a 360-day year consisting of twelve 30-day months.

SECTION 2.12. CUSIP NUMBERS.

            The Company in issuing any series of the Securities may use CUSIP
numbers, if then generally in use, and thereafter with respect to such series,
the Trustee may use such numbers in any notice of redemption or exchange with
respect to such series PROVIDED that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption

                                       25

<PAGE>

shall not be affected by any defect in or omission of such numbers. The Company
will promptly notify the Trustee of any change in the CUSIP numbers.

                     ARTICLE III. REDEMPTION OF SECURITIES.

SECTION 3.01. APPLICABILITY OF ARTICLE.

            Securities of any series which are redeemable before their Stated
Maturity will be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 2.01 for Securities of any
series) in accordance with this Article III.

SECTION 3.02. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

            (a) The election of the Company to redeem any Securities will be
evidenced by a Board Resolution. In case of any redemption at the election of
the Company of less than all the Securities of any series, the Company will, at
least 60 calendar days prior to the Redemption Date fixed by the Company (unless
a shorter notice shall be satisfactory to the Trustee), notify the Trustee of
such Redemption Date and of the principal amount of Securities of such series to
be redeemed. In the case of any redemption of Securities prior to the expiration
of any restriction on such redemption provided in the terms of such Securities
or elsewhere in this Indenture, the Company will furnish the Trustee with an
Officer's Certificate evidencing compliance with such restriction.

            (b) Notice of redemption of Securities to be redeemed at the
election of the Company will be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company and will
be irrevocable. Notice of redemption will be given by mail, first-class postage
prepaid, not less than 30 nor more than 60 calendar days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register. All notices of redemption will state (i) the Redemption
Date, (ii) the Redemption Price, (iii) if less than all the Outstanding
Securities of any series are to be redeemed, the identification (and, in the
case of partial redemption of any Securities, the principal amounts) of the
particular Securities to be redeemed, (iv) that on the Redemption Date the
Redemption Price will become due and payable upon each such Security to be
redeemed and, if applicable, that interest thereon will cease to accrue on and
after said date, (v) the place or places where such Securities are to be
surrendered for payment of the Redemption Price, (vi) that the redemption is for
a sinking fund, if such is the case, and (vii) the specific provision of this
Indenture pursuant to which such Securities are to be redeemed.

            (c) If less than all the Securities of any series are to be
redeemed, the particular Securities to be redeemed will be selected not more
than 60 calendar days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series not previously called for redemption, by
such method as the Trustee may deem fair and appropriate and which may provide
for the selection for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of
the principal amount of Securities of such series of a denomination larger than
the minimum authorized denomination

                                       26

<PAGE>

for Securities of that series. The Trustee will 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.

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

SECTION 3.03. DEPOSIT OF REDEMPTION PRICE.

            Prior to 10:00 a.m. on any Redemption Date specified in the notice
of redemption given as provided in Section 3.02, the Company will 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 6.03) an amount
of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) any accrued interest on, all
of the Securities that are to be redeemed on that date.

SECTION 3.04. SECURITIES PAYABLE ON REDEMPTION DATE.

            (a) Notice of redemption having been given as aforesaid, the
Securities so to be redeemed will, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Company defaults in the payment of the Redemption Price and accrued
interest) such Securities will cease to accrue interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security will
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; PROVIDED, HOWEVER, that, unless otherwise specified as
contemplated by Section 2.01, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates in accordance with their terms
and the provisions of Section 2.09.

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

SECTION 3.05. SECURITIES REDEEMED IN PART.

            Any Security that is to be redeemed only in part will be surrendered
at a Place of Payment therefor (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 his attorney
duly authorized in writing), and the Company will execute, and the Trustee will
authenticate and deliver to the Holder of such Security without service charge,
a new Security or Securities of the same series and of like tenor, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                           Article IV. Sinking Funds.

SECTION 4.01. APPLICABILITY OF ARTICLE.

            The provisions of this Article IV will be applicable to any sinking
fund for the retirement of Securities of a series except as otherwise specified
as contemplated by Section 2.01 for Securities of such series. The minimum
amount of any sinking fund payment provided for by the terms of Securities of
any series is herein referred to as a "mandatory sinking fund payment," and any
payment in excess of such minimum amount provided for by the terms of Securities
of any series is herein referred to as an "optional sinking fund payment." If
provided for by the terms of Securities of any series, the amount of any sinking
fund payment may be subject to reduction as provided in Section 4.02. Each
sinking fund payment with respect to Securities of a particular series will be
applied to the redemption of Securities of such series as provided for by the
terms of Securities of such series.

SECTION 4.02. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

            The Company (a) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (b) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series, provided that such Securities have not been previously so credited. Such
Securities will be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such sinking fund payment will be reduced
accordingly.

SECTION 4.03. REDEMPTION OF SECURITIES FOR SINKING FUND.

            Not less than 60 calendar days prior to each sinking fund payment
date for any series of Securities, the Company will deliver to the Trustee an
Officer's Certificate specifying the amount of the next ensuing sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, that is to be satisfied by payment of cash and the portion
thereof, if any, that is to be satisfied by delivering and crediting Securities
of that series pursuant to Section 4.02 and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 calendar days before each such
sinking fund payment date, the Trustee will select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 3.02(c)
and cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 3.02(b). Such notice
having been duly given, the redemption of such Securities will be made upon the
terms and in the manner stated in Sections 3.04 and 3.05.

            The Company may elect, at its option by Board Resolution at any
time, to have either Section 5.02 or Section 5.03 applied to the Outstanding
Securities of any series designated pursuant to Section 2.01 as being defeasible
pursuant to this Article V (hereinafter called "Defeasible Series"), upon
compliance with the conditions set forth below in this Article V, PROVIDED that
Section 5.02 will not apply to any series of Securities that is convertible into
Common Stock pursuant to Section 2.01(b)(xvi) or convertible into or
exchangeable for any other securities pursuant to Section 2.01(b)(xvii).

SECTION 5.02. DEFEASANCE AND DISCHARGE.

            Upon the Company's exercise of the option provided in Section 5.01
to have this Section 5.02 applied to the Outstanding Securities of any
Defeasible Series and subject to the proviso to Section 5.01, the Company will
be deemed to have been discharged from its obligations with respect to the
Outstanding Securities of such series as provided in this Section 5.02 on and
after the date the conditions set forth in Section 5.04 are satisfied
(hereinafter called "Defeasance"). For this purpose, such Defeasance means that
the Company will be deemed to have paid and discharged the entire indebtedness
represented by the Outstanding Securities of such series and to have satisfied
all its other obligations under the Securities of such series and this Indenture
insofar as the Securities of such series are concerned (and the Trustee, at the
expense of the Company, will execute proper instruments acknowledging the same),
subject to the following which will survive until otherwise terminated or
discharged hereunder: (a) the rights of Holders of Securities of such series to
receive, solely from the trust fund described in Section 5.04 and as more fully
set forth in Section 5.04, payments in respect of the principal of and any
premium and interest on such Securities of such series when payments are due,
(b) the Company's obligations with respect to the Securities of such series
under Sections 2.05, 2.06, 2.07, 6.02, 6.03, and 10.06, (c) the rights, powers,

Subject to compliance with this Article V, the Company may exercise its option
provided in Section 5.01 to have this Section 5.02 applied to the Outstanding
Securities of any Defeasible Series notwithstanding the prior exercise of its
option provided in Section 5.01 to have Section 5.03 applied to the Outstanding
Securities of such series.

SECTION 5.03. COVENANT DEFEASANCE.

            Upon the Company's exercise of the option provided in Section 5.01
to have this Section 5.03 applied to the Outstanding Securities of any
Defeasible Series, (a) the Company will be released from its obligations under
Sections 6.04 through 6.07, inclusive, Section 11.01, and the provisions of any
indenture supplemental hereto specified in such supplemental indenture, and (b)
the occurrence of any event specified in Sections 8.01(a)(iii), 8.01(a)(iv)
(with respect to any of Sections 6.04 through 6.07, inclusive, Section 11.01,
and the provisions of any indenture supplemental hereto specified in such
supplemental indenture), 8.01(a)(v), and 8.01(a)(viii) will be deemed not to be
or result in an Event of Default, in each case with respect to the Outstanding
Securities of such series as provided in this Section on and after the date the
conditions set forth

                                       29

in Section 5.04 are satisfied (hereinafter called "Covenant Defeasance"). For
this purpose, such Covenant Defeasance means that the Company may omit to comply
with and will have no liability in respect of any term, condition, or limitation
set forth in any such specified Section (to the extent specified above in the
case of Section 8.01(a)(iv) or in any such specified provision of such
supplemental indenture), whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or provision or by reason of any
reference in any such Section or provision to any other provision herein or in
any other document, but the remainder of this Indenture and the Securities of
such series will be unaffected thereby.

SECTION 5.04. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

            The following will be the conditions to application of either
Section 5.02 or Section 5.03 to the Outstanding Securities of any Defeasible
Series:

            (a) The Company shall irrevocably have deposited or caused to be
      deposited with the Trustee (or another trustee that satisfies the
      requirements contemplated by Section 9.08 and agrees to comply with the
      provisions of this Article V applicable to it) as trust funds in trust for
      the benefit of the Holders of Outstanding Securities of such series (i)
      money in an amount, or (ii) U.S. Government Obligations that through the
      scheduled payment of principal and interest in respect thereof in
      accordance with their terms will provide, without reinvestment, not later
      than one day before the due date of any payment, money in an amount, or
      (iii) a combination thereof, in each case sufficient to pay and discharge,
      and which will be applied by the Trustee (or any such other qualifying
      trustee) to pay and discharge, the principal of and any premium and
      interest on the Securities of such series on the respective Stated
      Maturities or on any earlier date or dates on which the Securities of such
      series shall be subject to redemption and the Company shall have given the
      Trustee irrevocable instructions satisfactory to the Trustee to give
      notice to the Holders of the redemption of the Securities of such series,
      all in accordance with the terms of this Indenture and the Securities of
      such series.

            (b) In the case of an election under Section 5.02, the Company shall
      have delivered to the Trustee an Opinion of Counsel (from a counsel who
      shall not be an employee of the Company) to the effect that (i) the
      Company has received from, or there has been published by, the Internal
      Revenue Service a ruling, or (ii) since the date of this Indenture there
      has been a change in the applicable federal income tax law, in either case
      to the effect that, and based thereon, such opinion shall confirm that,
      the Holders of the Outstanding Securities of such series will not
      recognize gain or loss for federal income tax purposes as a result of the
      deposit, Defeasance, and discharge to be effected with respect to the
      Securities of such series and will be subject to federal income tax on the
      same amount, in the same manner, and at the same times as would be the
      case if such deposit, Defeasance, and discharge were not to occur.

            (c) In the case of an election under Section 5.03, the Company shall
      have delivered to the Trustee an Opinion of Counsel (from a counsel who
      shall not be an employee of the Company) to the effect that the Holders of
      the Outstanding Securities of such series will not recognize gain or loss
      for federal income tax purposes as a result of

                                       30

<PAGE>

      the deposit and Covenant Defeasance to be effected with respect to the
      Securities of such series and will be subject to federal income tax on the
      same amount, in the same manner, and at the same times as would be the
      case if such deposit and Covenant Defeasance were not to occur.

            (d) The Company shall have delivered to the Trustee an Officer's
      Certificate to the effect that the Securities of such series, if then
      listed on any securities exchange, will not be delisted solely as a result
      of such deposit.

            (e) No Event of Default or event that (after notice or lapse of time
      or both) would become an Event of Default shall have occurred and be
      continuing at the time of such deposit or, with regard to any Event of
      Default or any such event specified in Sections 8.01(a)(vi) and (vii), at
      any time on or prior to the 90th calendar day after the date of such
      deposit (it being understood that this condition will not be deemed
      satisfied until after such 90th calendar day).

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

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

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

            (i) Such Defeasance or Covenant Defeasance will not result in the
      trust arising from such deposit constituting an investment company within
      the meaning of the Investment Company Act of 1940, as amended, unless such
      trust will be qualified under such Act or exempt from regulation
      thereunder.

SECTION 5.05. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
              TRUST; OTHER MISCELLANEOUS PROVISIONS.

            (a) Subject to the provisions of Section 6.03(e), all money and U.S.
Government Obligations (including the proceeds thereof) deposited with the
Trustee or other qualifying trustee (solely for purposes of this Section 5.05
and Section 5.06, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 5.04 in respect of the
Securities of any Defeasible Series will be held in trust and applied by the
Trustee, in accordance with the provisions of the Securities of such series and
this Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of Securities of such series, of all sums due and to
become due thereon in respect of principal and any premium and interest, but
money so held in trust need not be segregated from other funds except to the
extent required by law.

                                       31

<PAGE>

            (b) The Company will pay and indemnify the Trustee against any tax,
fee, or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 5.04 or the principal and interest
received in respect thereof other than any such tax, fee, or other charge that
by law is for the account of the Holders of Outstanding Securities.

            (c) Notwithstanding anything in this Article V to the contrary, the
Trustee will deliver or pay to the Company from time to time upon a Company
Request any money or U.S. Government Obligations held by it as provided in
Section 5.04 with respect to Securities of any Defeasible Series that are in
excess of the amount thereof that would then be required to be deposited to
effect an equivalent Defeasance or Covenant Defeasance with respect to the
Securities of such series.

SECTION 5.06. REINSTATEMENT.

            If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article V with respect to the Securities of any series by
reason of any order or judgment of any court or governmental authority
enjoining, restraining, or otherwise prohibiting such application, then the
Company's obligations under this Indenture and the Securities of such series
will be revived and reinstated as though no deposit had occurred pursuant to
this Article V with respect to Securities of such series until such time as the
Trustee or Paying Agent is permitted to apply all money held in trust pursuant
to Section 5.05 with respect to Securities of such series in accordance with
this Article V; PROVIDED, HOWEVER, that if the Company makes any payment of
principal of or any premium or interest on any Security of such series following
the reinstatement of its obligations, the Company will be subrogated to the
rights of the Holders of Securities of such series to receive such payment from
the money so held in trust.

                ARTICLE VI. PARTICULAR COVENANTS OF THE COMPANY.

SECTION 6.01. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST ON SECURITIES.

            The Company, for the benefit of each series of Securities, will duly
and punctually pay the principal of and any premium and interest on the
Securities of that series in accordance with the terms of such Securities and
this Indenture.

SECTION 6.02. MAINTENANCE OF OFFICE OR AGENCY.

            (a) The Company will maintain in each Place of Payment for any

presented or surrendered for payment, where Securities of that series may be
surrendered for registration of transfer or exchange, and where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices, and demands may be made or served at
the Corporate Trust Office, and the Company hereby appoints the Trustee as its
agent to receive all such presentations, surrenders, notices, and demands.

                                       32

<PAGE>

            (b) The Company may also from time to time designate one or more
other offices or agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time
rescind such designations; PROVIDED, HOWEVER, that no such designation or
rescission will in any manner relieve the Company of its obligation to maintain
an office or agency in each Place of Payment for Securities of any series for
such purposes. The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.

SECTION 6.03. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

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

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

            (c) The Company will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent will agree with the Trustee, subject to
the provisions of this Section 6.03, that such Paying Agent will (i) comply with
the provisions of the Trust Indenture Act applicable to it as a Paying Agent and
(ii) during the continuance of any default by the Company (or any other obligor
upon the Securities of that series) in the making of any payment in respect of
the Securities of that series, and upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

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

            (e) Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of or any
premium or interest on any Security of any series and remaining unclaimed for
two years after such principal, premium, or interest has become due and payable
will be paid to the Company upon a Company Request (or, if then held by the
Company, will be discharged from such trust); and the Holder of such Security
will thereafter, as an unsecured general creditor, look only to the Company for
payment thereof,

                                       33

<PAGE>

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, will thereupon
cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the Borough of
Manhattan, The City of New York, notice that such money remains unclaimed and
that, after a date specified therein, which will not be less than 30 calendar
days from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

SECTION 6.04. PAYMENT OF TAXES AND OTHER CLAIMS.

            The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (a) all taxes, assessments, and
governmental charges levied or imposed upon the Company or any Subsidiary of the
Company or upon the income, profits, or property of the Company or any
Subsidiary of the Company, and (b) all lawful claims for labor, materials, and
supplies, in each case which, if unpaid, might by law become a lien upon the
property of the Company or any Subsidiary of the Company and might have a
Material Adverse Effect; PROVIDED, HOWEVER, that the Company will not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge, or claim the amount, applicability, or validity of which is
being contested in good faith by appropriate proceedings.

SECTION 6.05. MAINTENANCE OF PROPERTIES.

            The Company will cause all properties used or useful in the conduct
of its business or the business of any Subsidiary of the Company to be
maintained and kept in good condition, repair, and working order and supplied
with all necessary equipment and will cause to be made all necessary repairs,
renewals, replacements, betterments, and improvements thereof, all as in the
judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
PROVIDED, HOWEVER, that nothing in this Section 6.05 will prevent the Company
from discontinuing the operation or maintenance of any of such properties if
such discontinuance is, in the judgment of the Company, desirable in the conduct
of its business or the business of any Subsidiary of the Company and will not
result in a Material Adverse Effect.

SECTION 6.06. EXISTENCE.

            Subject to Article XI, the Company will, and will cause each of its
Subsidiaries to, do or cause to be done all things necessary to preserve and
keep in full force and effect its existence, rights (charter and statutory), and
franchises; PROVIDED, HOWEVER, that no Subsidiary of the Company will be
required to preserve its existence, and neither the Company nor any Subsidiary
of the Company will be required to preserve any such right or franchise, if the
Board of Directors determines that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss
thereof will not result in a Material Adverse Effect.

                                       34

<PAGE>

SECTION 6.07. COMPLIANCE WITH LAWS.

            The Company will, and will cause each of its Subsidiaries to, comply
with all applicable federal, state, local, or foreign laws, rules, regulations,
or ordinances, including without limitation such laws, rules, regulations, or
ordinances relating to pension, environmental, employee, and tax matters, in
each case to the extent that the failure so to comply would have a Material
Adverse Effect.

SECTION 6.08. STATEMENT BY OFFICERS AS TO DEFAULT.

            The Company will deliver to the Trustee, within 120 calendar days
after the end of each fiscal year of the Company ending after the date hereof,
an Officer's Certificate signed by the principal executive officer, principal
financial officer, or principal accounting officer of the Company stating
whether or not to the knowledge of such person after due inquiry the Company is
in default in the performance and observance of any of the terms, provisions,
and conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Company is in default,
specifying all such defaults and the nature and status thereof of which such
person may have such knowledge.

SECTION 6.09. WAIVER OF CERTAIN COVENANTS.

            The Company may omit in any particular instance to comply with any
term, provision, or condition set forth in Sections 6.04 through 6.07,
inclusive, and the provisions of any supplemental indenture specified in such
supplemental indenture, with respect to the Securities of any series if the
Holders of a majority in principal amount of the Outstanding Securities of such
series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision, or condition,
but no such waiver will extend to or affect such term, provision, or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision, or condition will remain in full force and
effect.

            (b) The rights of the Holders to communicate with other Holders with
respect to their rights under this Indenture or under the Securities, and the
corresponding rights and privileges of the Trustee, will be as provided by the
Trust Indenture Act.

notify the Trustee when any Securities are listed on any stock exchange or of
any delisting thereof.

SECTION 7.04. REPORTS BY COMPANY.

            The Company will file with the Trustee and the Commission, and
transmit to Holders, such information, documents, and other reports, and such

Securities of any series, means any one of the following events (whatever the
reason for such Event of Default and whether it may be voluntary or involuntary
or be effected by operation of law or pursuant to any judgment, decree, or order
of any court or any order, rule, or regulation of any administrative or
governmental body):

                  (i) default in the payment of any interest on any Security of
      that series when it becomes due and payable, and continuance of such
      default for a period of 30 calendar days;

                  (ii) default in the payment of the principal of (or premium,
      if any, on) any Security of that series when it becomes due and payable;

      and as due by the terms of a Security of that series;

                  (iv) default in the performance, or breach, of any covenant or
      warranty of the Company in this Indenture (other than a covenant or
      warranty, a default in the performance or breach of which is elsewhere in
      this Section 8.01 specifically dealt with or which has expressly been
      included in this Indenture solely for the benefit of one or more series of
      Securities other than that series), and continuance of such default or
      breach for a period of 60 calendar days after there has been given, by
      registered or certified mail, to the Company by the Trustee or to the
      Company and the Trustee by the Holders of at least 25% in principal amount
      of the Outstanding Securities of that series 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;

                  (v) any nonpayment at maturity or other default is made under
      any agreement or instrument relating to any other Indebtedness of the
      Company (the unpaid principal amount of which is not less than $25.0
      million), and, in any such case, such default (A) continues beyond any
      period of grace provided with respect thereto and (B) results in such
      Indebtedness becoming due prior to its stated maturity or occurs at the
      final maturity of such Indebtedness; PROVIDED, HOWEVER, that, subject to
      the provisions of Section 9.01 and 8.08, the Trustee will not be deemed to
      have knowledge of such nonpayment or other default unless either (1) a
      Responsible Officer of the Trustee has actual knowledge of nonpayment or
      other default or (2) the Trustee has received written notice thereof from
      the Company, from any Holder, from the holder of any such Indebtedness or
      from the trustee under the agreement or instrument relating to such
      Indebtedness;

                                       37

<PAGE>

                  (vi) the entry by a court having jurisdiction in the premises
      of (A) a decree or order for relief in respect of the Company in an
      involuntary case or proceeding under any applicable federal or state
      bankruptcy, insolvency, reorganization, or other similar law or (B) a
      decree or order adjudging the Company a bankrupt or insolvent, or
      approving as properly filed a petition seeking reorganization,
      arrangement, adjustment, or composition of or in respect of the Company
      under any applicable federal or state law, or appointing a custodian,
      receiver, liquidator, assignee, trustee, sequestrator, or other similar
      official of the Company or of any substantial part of its property, or
      ordering the winding up or liquidation of its affairs, and the continuance
      of any such decree or order for relief or any such other decree or order
      unstayed and in effect for a period of 60 consecutive calendar days;

                  (vii) the commencement by the Company 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 it to the entry
      of a decree or order for relief in respect of the Company in an
      involuntary 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
      it, or the filing by it of a petition or answer or consent seeking
      reorganization or relief with respect to the Company under any applicable
      federal or state bankruptcy, insolvency, reorganization, or other similar
      law, or the consent by it to the filing of such petition or to the
      appointment of or taking possession by a custodian, receiver, liquidator,
      assignee, trustee, sequestrator, or other similar official of the Company
      or of any substantial part of its property pursuant to any such law, or
      the making by it of an assignment for the benefit of creditors, or the
      admission by it in writing of its inability to pay its debts generally as
      they become due, or the taking of corporate action by the Company in
      furtherance of any such action; or

                  (viii) any other Event of Default provided with respect to
      Securities of that series.

            (b) If an Event of Default (other than an Event of Default arising
under Section 8.01(a)(vi) or (vii)) with respect to Securities of any series at
the time Outstanding occurs and is continuing, then in every case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified in the terms
thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) will become immediately due and payable. If an Event of Default under
Section 8.01(a)(vi) or (vii) occurs, then the principal of, premium, if any, and
accrued interest on the Securities shall become immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder.

            (c) At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment or
decree for payment of the money

                                       38

<PAGE>

due has been obtained by the Trustee as hereinafter in this Article VIII
provided, the Holders of a majority in principal amount of the outstanding
Securities of that series, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if (i) the Company has
paid or deposited with the Trustee a sum sufficient to pay (A) all overdue
interest on all Securities of that series, (B) the principal of (and premium, if
any, on) any Securities of that series which have become due otherwise than by
such declaration of acceleration and any interest thereon at the rate or rates
prescribed therefor in such Securities, (C) to the extent that payment of such
interest is lawful, interest upon overdue interest at the rate or rates
prescribed therefor in such Securities, and (D) all sums paid or advanced by the
Trustee hereunder and the reasonable compensation, expenses, disbursements, and
advances of the Trustee and its agents and counsel and (ii) all Events of
Default with respect to Securities of that series, other than the non-payment of
the principal of Securities of that series which have become due solely by such
declaration of acceleration, have been cured or waived as provided in Section
8.01(d). No such rescission will affect any subsequent default or impair any
right consequent thereon.

            (d) The Holders of a majority in principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all the Securities of
such series waive any past default hereunder with respect to such series and its
consequences, except a default (i) in the payment of the principal of or any
premium or interest on any Security of such series or (ii) in respect of a
covenant or provision hereof which under Article X cannot be modified or amended
without the consent of the Holder of each Outstanding Security of such series
affected. Upon any such waiver, such default will cease to exist, and any Event
of Default arising therefrom will be deemed to have been cured, for every
purpose of this Indenture, but no such waiver will extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 8.02. COVENANT OF COMPANY TO PAY TO TRUSTEE WHOLE AMOUNT DUE ON
              SECURITIES ON DEFAULT IN PAYMENT OF INTEREST OR PRINCIPAL; SUITS
              FOR ENFORCEMENT BY TRUSTEE.

            (a) The Company covenants that if (i) default is made in the payment
of any interest on any Security when such interest becomes due and payable and
such default continues for a period of 30 calendar days or (ii) default is made
in the payment of the principal of (or premium, if any, on) any Security when it
becomes due and payable, the Company will, upon demand of the Trustee, pay to
it, for the benefit of the Holders of such Securities, the whole amount then due
and payable on such Securities for principal and any premium and interest and,
to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal and premium and on any overdue interest, at
the rate or rates prescribed therefor in such Securities, and, in addition
thereto, such further amount as will be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements, and advances of the Trustee and its agents and counsel. If the
Company shall fail forthwith to pay such amounts upon such demand, the Trustee,
in its own name and as trustee of an express trust, shall be entitled and
empowered to institute any actions or proceedings at law or in equity for the
collection of the sums so due and unpaid, and may prosecute any such action or
proceeding to judgment or final decree, and may enforce any such judgment or
final decree against the Company and collect in the manner provided by law out
of the property of the Company, wherever situated, the moneys adjudged or
decreed to be payable.

                                       39

<PAGE>

            (b) If an Event of Default with respect to Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series 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.

            (c) In case of any judicial proceeding relative to the Company (or
any other obligor upon the Securities), its property or its creditors, the
Trustee will be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee will be authorized to collect and receive
any money 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 consents to the making of such payments directly to
the Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements, and advances of the Trustee and its
agents and counsel, and any other amounts due the Trustee under Section 9.06.

            (d) No provision of this Indenture will 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, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

            (e) 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 will be brought in
its own name as trustee of an express trust, and any recovery of judgment will,
after provision for the payment of the reasonable compensation, expenses,
disbursements, and advances of the Trustee and its agents and counsel, be for
the ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 8.03. APPLICATION OF MONEY COLLECTED BY TRUSTEE.

            Any money collected by the Trustee pursuant to this Article VIII
will be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
or any premium or interest, upon presentation of the Securities 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 9.06;

                                       40

<PAGE>

            SECOND:     To the payment of the amounts then due and unpaid for
                        principal of and any premium 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, except to the extent
                        that the Securities of a series are by their express
                        terms subordinated and subject in right of payment to
                        the prior payment of other indebtedness, according to
                        the amounts due and payable on such Securities for
                        principal and any premium and interest, respectively;
                        and

            THIRD:      To the Company, its successors or assigns, or to such
                        other Person that may be lawfully entitled to receive
                        the same.

SECTION 8.04. LIMITATION ON SUITS BY HOLDERS OF SECURITIES.

            No Holder of any Security of any series will 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 has previously given written notice to the
Trustee of a continuing Event of Default with respect to the Securities of that
series, (b) the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series 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 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 calendar days after its
receipt of such notice, request, and offer of indemnity has failed to institute
any such proceeding, and (e) 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 principal amount of the Outstanding Securities of that series, it
being understood and intended that no one or more of such Holders will 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 8.05. RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION IN
              EXERCISE OF RIGHTS NOT A WAIVER OF EVENT OF DEFAULT.

            (a) Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost, or stolen Securities in the last
paragraph of Section 2.07, 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 will, 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, will not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

                                       41

<PAGE>

            (b) No delay or omission of the Trustee or of any Holder of any
Securities to exercise any right or remedy accruing upon any Event of Default
will 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

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.

SECTION 9.08. CORPORATE TRUSTEE REQUIRED ELIGIBILITY.

and has a combined capital and surplus of at least $100,000,000. If such
Person publishes reports of condition at least annually, pursuant to law or
to the requirements of a supervising or examining state or federal authority,
then for the purposes of this Section 9.08, the combined capital and surplus
of such Person 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 9.08, it will resign immediately in the manner and with the effect
hereinafter specified in this Article IX.

SECTION 9.09. 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 IX will become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 9.10.

            (b) The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 9.10 shall not have been delivered to the Trustee within 30 calendar
days after the giving of such notice of resignation, the resigning Trustee may
at the expense of the Company petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

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

            (d) If, at any time, (i) the Trustee fails to comply with Section
9.07 after written request therefor by the Company or by any Holder who has been
a bona fide Holder of a Security for at least six months, (ii) the Trustee
ceases to be eligible under Section 9.08 and fails to resign after written
request therefor by the Company or by any such Holder, or (iii) the Trustee
becomes incapable of acting or is adjudged a bankrupt or insolvent or a receiver
of the Trustee or of its property is appointed or any public officer takes
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, (A) the
Company by a Board Resolution may remove the Trustee with respect to all
Securities or (B) subject to Section 8.07, any Holder who has been a bona fide
Holder of a Security 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 with respect to all Securities and the appointment of a
successor Trustee or Trustees.

<PAGE>

            (e) If the Trustee resigns, is removed, or becomes incapable of
acting, or if a vacancy occurs in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company by a Board
Resolution will promptly appoint a successor Trustee or Trustees with respect to
the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there will be only one Trustee with
respect to the Securities of any particular series) and will comply with the
applicable requirements of Section 9.10. If, within one year after such
resignation, removal, or incapability or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series is appointed by
Act of the Holders of a majority in principal amount of the Outstanding
Securities of such series delivered to the Company and the retiring Trustee, the
successor Trustee so appointed will, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 9.10,
become the successor Trustee with respect to the Securities of such series and
to that extent supersede the successor Trustee appointed by the Company. If no
successor Trustee with respect to the Securities of any series shall have been
so appointed by the Company or the Holders and accepted appointment in the
manner required by Section 9.10, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, at the expense of the Company, petition any court
of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

            (f) The Company will give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to all holders of Securities of such series in the manner provided in Section
13.03. Each notice will include the name of the successor Trustee with respect
to the Securities of such series and the address of its Corporate Trust Office.

SECTION 9.10. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

            (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed will
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 will become effective and such successor Trustee,
without any further act, deed, or conveyance, will become vested with all the
rights, powers, trusts, and duties of the retiring Trustee, but, on the request
of the Company or the successor Trustee, such retiring Trustee will, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers, and duties of the retiring Trustee and
will duly assign, transfer, and deliver to such Trustee all property and money
held by such retiring Trustee hereunder.

            (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee, and each successor Trustee with respect to the Securities of
one or more series will execute and deliver an indenture supplemental hereto
wherein such successor Trustee will accept such appointment and which (i) will
contain such provisions as may be necessary or desirable to transfer and confirm
to, and to vest in, each successor Trustee all the rights, powers, trusts, and
duties of the retiring

                                       47

<PAGE>

Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (ii) will contain such provisions
as may be deemed necessary or desirable to confirm that all the rights, powers,
trusts, and duties of the retiring Trustee with respect to the Securities of
that or those series as to which the retiring Trustee is not retiring will
continue to be vested in the retiring Trustee, and (iii) will add to or change
any of the provisions of this Indenture as may be necessary to provide for or
facilitate the administration of the trusts hereunder by more than one Trustee,
it being understood that nothing herein or in such supplemental indenture will
constitute such Trustees co-trustees of the same trust and that each such
Trustee will be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustees and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee will become effective to the extent provided
therein and each such successor Trustee, without any further act, deed, or
conveyance, will become vested with all the rights, powers, trusts, and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but on request of
the Company or any successor Trustee, such retiring Trustee will duly assign,
transfer, and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Company will
execute any and all instruments reasonably required to more fully and certainly
vest in and confirm to such successor Trustee all applicable rights, powers, and
trusts referred to in the preceding paragraphs of this Section 9.10.

            (d) No successor Trustee will accept its appointment unless at the
time of such acceptance such successor Trustee is qualified and eligible under
this Article IX.

SECTION 9.11. 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 may be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, will be the successor of the Trustee hereunder, provided such
corporation is otherwise qualified and eligible under this Article IX, 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 9.12. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

            If and when the Trustee is or becomes a creditor of the Company (or
any other obligor upon the Securities), the Trustee will be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

SECTION 9.13. APPOINTMENT OF AUTHENTICATING AGENT.

            (a) The Trustee may appoint an Authenticating Agent or Agents with
respect to one or more series of Securities which will be authorized to act on
behalf of the Trustee to authenticate Securities of such series issued upon
original issue and upon exchange, registration of transfer, or partial
redemption thereof or pursuant to Section 2.07, and Securities so authenticated
will be entitled to the benefits of this Indenture and will 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 will 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 thereof, or the District of Columbia, 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 9.13,
the combined capital and surplus of such Authenticating Agent will 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 the provisions of this Section 9.13, such
Authenticating Agent will resign immediately in the manner and with the effect
specified in this Section 9.13.

            (b) 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
may be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, will continue to be an
Authenticating Agent, provided such corporation is otherwise eligible under this
Section 9.13, without the execution or filing of any paper or any further act on
the part of the Trustee or the Authenticating Agent.

            (c) An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to 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 to 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 this Section 9.13, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and will mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder will
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 will be appointed unless eligible under the
provisions of this Section 9.13.

            (d) The Company agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section 9.13.

            (e) If an appointment with respect to one or more series of
Securities is made pursuant to this Section 9.13, the Securities of such series
may have endorsed thereon, in addition to the Trustee's certificate of
authentication, an alternative form of certificate of authentication in the
following form:

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

Company may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the
date on and/or after which such action is proposed to be taken or such
omission is proposed to be effective. In the case of any proposed action or
omission expressly authorized by this Indenture, the Trustee shall not be
liable for any action taken by, or omission of, the Trustee in accordance
with a proposal included in such application on or after the date specified
in such application (which date shall not be less than three Business Days
after the date any officer of the Company actually receives such application
by telecopy, e-mail, or otherwise (provided that such receipt shall have been

      such covenants are expressly being included solely for the benefit of such
      series) or to surrender any right or power herein conferred upon the
      Company;

            (c) to add any additional Events of Default;

            (d) to add to or change any of the provisions of this Indenture to

      and with or without interest coupons, or to permit or facilitate the
      issuance of Securities in uncertificated form;

            (e) to add to, change, or eliminate any of the provisions of this
      Indenture in respect of one or more series of Securities, PROVIDED that
      any such addition, change, or elimination (i) will neither (A) apply to
      any Security of any series created prior to the execution of such
      supplemental indenture and entitled to the benefit of such provision nor
      (B) modify the rights of the Holder of any such Security with respect to
      such provision or (ii) will become effective only when there is no such

      more series and to add to or change any of the provisions of this
      Indenture as may be necessary to provide for or facilitate the
      administration of the trusts hereunder by more than one Trustee, pursuant
      to the requirements of Section 9.10; or

                                       51

            (h) to cure any ambiguity, to correct or supplement any provision
      herein which may be defective or inconsistent with any other provision
      herein, or to make any other provisions with respect to matters or
      questions arising under this Indenture, PROVIDED that such action pursuant
      to this clause (h) will not adversely affect the interests of the Holders
      of Securities of any series in any material respect.

SECTION 10.02. MODIFICATION OF INDENTURE WITH CONSENT OF HOLDERS OF AT
               LEAST A MAJORITY IN PRINCIPAL AMOUNT OF OUTSTANDING SECURITIES.

            (a) With the consent of the Holders of a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; PROVIDED, HOWEVER,
that no such supplemental indenture will, without the consent of the Holder of
each Outstanding Security affected thereby:

            (i) change the Stated Maturity of the principal of, or any
      installment of principal of or interest on, any Security, or reduce the
      principal amount thereof or the rate of interest thereon or any premium
      payable upon the redemption thereof, or reduce the amount of the principal
      of an Original Issue Discount Security that would be due and payable upon
      a declaration of acceleration of the Maturity thereof pursuant to Section
      8.01(b), or change any Place of Payment where, or the coin or currency in
      which, any Security or any premium or interest thereon is payable, or
      impair the right to institute suit for the enforcement of any such payment
      on or after the Stated Maturity thereof (or, in the case of redemption, on
      or after the Redemption Date);

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

            (iii) modify any of the provisions of this Section 10.02, Section
      8.01(d) or Section 6.09, except to increase the percentage in principal
      amount of Holders required under any such Section or to provide that
      certain other provisions of this Indenture cannot be modified or waived
      without the consent of the Holder of each Outstanding Security affected
      thereby, PROVIDED, HOWEVER, that this clause (iii) will not be deemed to
      require the consent of any Holder with respect to changes in the
      references to "the Trustee" and concomitant changes in this Section 10.02
      and Section 6.09, or the deletion of this proviso, in accordance with the
      requirements of Sections 9.10 and 10.01(g).

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

                                       52

<PAGE>

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

            (c) It will not be necessary for any Act of Holders under this
Section 10.02 to approve the particular form of any proposed supplemental
indenture, but it will be sufficient if such Act approves the substance thereof.

SECTION 10.03. EXECUTION OF SUPPLEMENTAL INDENTURES.

            In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article X or the modifications thereby
of the trusts created by this Indenture, the Trustee will be entitled to
receive, and (subject to Section 9.01) will be fully protected in relying upon,
an Officers' Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but will not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties, or immunities under
this Indenture or otherwise.

SECTION 10.04. EFFECT OF SUPPLEMENTAL INDENTURES.

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

SECTION 10.05. CONFORMITY WITH TRUST INDENTURE ACT.

            Every supplemental indenture executed pursuant to this Article X
will conform to the requirements of the Trust Indenture Act.

SECTION 10.06. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

            Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article X may, and will
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the 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 of such series.

             ARTICLE XI. CONSOLIDATION, MERGER, SALE, OR TRANSFER.

SECTION 11.01. CONSOLIDATIONS AND MERGERS OF COMPANY AND SALES PERMITTED ONLY
               ON CERTAIN TERMS.

            (a) The Company shall not consolidate with or merge with or into any
other Person, or transfer (by lease, assignment, sale, or otherwise) all or
substantially all of its

                                       53

<PAGE>

properties and assets to another Person unless (i) either (A) the Company shall
be the continuing or surviving Person in such a consolidation or merger or (B)
the Person (if other than the Company) formed by such consolidation or into
which the Company is merged or to which all or substantially all of the
properties and assets of the Company are transferred (the Company or such other
Person being referred to as the "Surviving Person") shall be a corporation
organized and validly 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, all of the obligations of the Company under the
Securities and the Indenture, (ii) immediately after the transaction and the
incurrence or anticipated incurrence of any Indebtedness to be incurred in
connection therewith, no Default will exist, and (iii) an Officer's Certificate
has been delivered to the Trustee to the effect that the conditions set forth in
the preceding clauses (i) and (ii) have been satisfied and an Opinion of Counsel
(from a counsel who shall not be an employee of the Company) has been delivered
to the Trustee to the effect that the conditions set forth in the preceding
clause (i) have been satisfied.

            (b) The Surviving Person will succeed to and be substituted for the
Company with the same effect as if it had been named herein as a party hereto,
and thereafter the predecessor corporation will be relieved of all obligations
and covenants under this Indenture and the Securities.

             ARTICLE XII. SATISFACTION AND DISCHARGE OF INDENTURE.

SECTION 12.01. SATISFACTION AND DISCHARGE OF INDENTURE.

            This Indenture will upon a Company Request cease to be of further
effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for), and the Trustee, at the
expense the Company, will execute proper instruments acknowledging satisfaction
and discharge of this Indenture, when: (a) either (i) all Securities theretofore
authenticated and delivered (other than (A) Securities which have been
destroyed, lost, or stolen and which have been replaced or paid as provided in
Section 2.07 and (B) Securities for the payment of which money has theretofore
been deposited in trust or segregated and held in trust by the Company and
thereafter repaid to the Company or discharged from such trust, as provided in
Section 6.03) have been delivered to the Trustee for cancellation or (ii) all
such Securities not theretofore delivered to the Trustee for cancellation (A)
have become due and payable, (B) will become due and payable at their Stated
Maturity within one year, or (C) are to be called for redemption within one year
under arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company, and
the Company, in the case of clause (A), (B), or (C) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for such purpose
an amount sufficient to pay and discharge the entire indebtedness on such
Securities not theretofore delivered to the Trustee for cancellation, for
principal and any premium and interest to the date of such deposit (in the case
of Securities which have become due and payable) or to the Stated Maturity or
Redemption Date, as the case may be; (b) the Company has paid or caused to be
paid all other sums payable hereunder by the Company; and (c) the Company has
delivered to the Trustee an Officer's Certificate and an Opinion of Counsel,
each stating that all conditions precedent herein provided for relating to the
satisfaction and discharge of this Indenture have been satisfied.

                                       54

<PAGE>

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 9.06, the obligations of
the Trustee to any Authenticating Agent under Section 9.13, and, if money shall
have been deposited with the Trustee pursuant to subclause (ii) of clause (a) of
this Section 12.01, the obligations of the Trustee under Sections 6.03(e) and
12.02, will survive.

SECTION 12.02. APPLICATION OF TRUST MONEY.

            Subject to provisions of Section 6.03(e), all money deposited with
the Trustee pursuant to Section 12.01 will be held in trust and applied by it,
in accordance with the provisions of the Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal and any premium and interest for the payment
of which such money has been deposited with the Trustee; and such money shall be
segregated from other funds to the extent required by law.

                     ARTICLE XIII. MISCELLANEOUS PROVISIONS.

SECTION 13.01. SUCCESSORS AND ASSIGNS OF COMPANY BOUND BY INDENTURE.

            All the covenants, stipulations, promises, and agreements in this
Indenture contained by or on behalf of the Company will bind its successors and
assigns, whether so expressed or not.

SECTION 13.02. SERVICE OF REQUIRED NOTICE TO TRUSTEE AND COMPANY.

            Any request, demand, authorization, direction, notice, consent,
waiver, Act of Holders, or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with (a) the
Trustee by any Holder or by the Company will be sufficient for every purpose
hereunder if made, given, furnished, or filed in writing to or with the
Trustee at its Corporate Trust Office, or (b) the Company by the Trustee or
by any Holder will be sufficient for every purpose hereunder (unless
otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to the Company addressed to it at 111 S.W. Fifth Avenue,
Portland,Oregon 97204 (marked for the attention of both the Chief Financial
Officer and the General Counsel) or at any other address previously furnished
in writing to the Trustee by the Company.

SECTION 13.03. SERVICE OF REQUIRED NOTICE TO HOLDERS; WAIVER.

            Where this Indenture provides for notice to Holders of any event,
such notice will be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at his address as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice. 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 will affect the
sufficiency of such notice with respect to other Holders. Where

                                       55

<PAGE>

this Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver will be the equivalent of such notice. Waivers of
notice by Holders will be filed with the Trustee, but such filing will not be a
condition precedent to the validity of any action taken in reliance upon such
waiver. 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 by mail, then
such notification as may be made with the approval of the Trustee will
constitute a sufficient notification for every purpose hereunder.

SECTION 13.04. INDENTURE AND SECURITIES TO BE CONSTRUED IN ACCORDANCE
               WITH THE LAWS OF THE STATE OF NEW YORK.

            This Indenture and the Securities will be deemed to be a contract
made under the laws of the State of New York, and for all purposes will be
construed in accordance with the laws of said State without giving effect to
principles of conflict of laws of such State.

SECTION 13.05. COMPLIANCE CERTIFICATES AND OPINIONS.

            Upon any application or request by the Company to the Trustee to
take any action under any of the provisions of this Indenture, the Company will
furnish to the Trustee such certificates and opinions as may be required under
the Trust Indenture Act. Each such certificate or opinion will be given in the
form of an Officer's Certificate, if to be given by an officer of the Company,
or an Opinion of Counsel, if to be given by counsel, and will comply with the
requirements of the Trust Indenture Act and any other requirements set forth in
this Indenture.

SECTION 13.06. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

            In any case where several matters are required to be certified by,
or covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents. Where any
Person is required to make, give, or execute two or more applications, requests,
consents, certificates, statements, opinions, or other instruments under this
Indenture, they may, but need not, be consolidated and form one instrument.

SECTION 13.07. PAYMENTS DUE ON NON-BUSINESS DAYS.

            In any case where any Interest Payment Date, Redemption 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 of the Securities of any series which
specifically states that such provision will apply in lieu of this Section
13.07)) payment of interest or principal (and premium, if any) 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, without additional interest, with the
same force and effect as if made on the

                                       56

<PAGE>

applicable Interest Payment Date or Redemption Date or at the applicable Stated
Maturity, as the case may be.

SECTION 13.08. PROVISIONS REQUIRED BY TRUST INDENTURE ACT TO CONTROL.

            If any provision of this Indenture limits, qualifies, or conflicts
with the duties imposed on any Person by Sections 310 through 317, inclusive, of
the Trust Indenture Act (including provisions automatically deemed included in
this Indenture pursuant to the Trust Indenture Act unless this Indenture
provides that such provisions are excluded), which are deemed to be a part of
and govern this Indenture, whether or not contained herein, then such imposed
duties will control.

SECTION 13.09. INVALIDITY OF PARTICULAR PROVISIONS.

            In case any one or more of the provisions contained in this
Indenture or in the Securities is for any reason held to be invalid, illegal, or
unenforceable in any respect, such validity, illegality, or enforceability will
not affect any other provision of this Indenture or of the Securities, but this
Indenture and such Securities will be construed as if such invalid, illegal, or
unenforceable provision had never been contained herein or therein.

SECTION 13.10. INDENTURE MAY BE EXECUTED IN COUNTERPARTS.

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

SECTION 13.11. ACTS OF HOLDERS; RECORD DATES.

            (a) Any request, demand, authorization, direction, notice, consent,
waiver, or other action provided or permitted by this Indenture to be 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 agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action will become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. 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 will be sufficient for any purpose of this
Indenture and (subject to Section 9.01) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section 13.11.

            (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. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit will also constitute sufficient proof of
his authority. The fact and date of

                                       57

<PAGE>

the execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner which the Trustee
deems sufficient.

            (c) The ownership of Securities will be proved by the Security
Register.

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

            (e) The Company may, in the circumstances permitted by the Trust
Indenture Act, set any day as the record date for the purpose of determining the
Holders of Outstanding Securities of any series entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver, or other
action provided or permitted by this Indenture to be given or taken by Holders
of Securities of such series. With regard to any record date set pursuant to
this paragraph, the Holders of Outstanding Securities of the relevant series on
such record date (or their duly appointed agents), and only such Persons, will
be entitled to give or take the relevant action, whether or not such Holders
remain Holders after such record date. With regard to any action that may be
given or taken hereunder only by Holders of a requisite principal amount of
Outstanding Securities of any series (or their duly appointed agents) and for
which a record date is set pursuant to this paragraph, the Company may, at its
option, set an expiration date after which no such action purported to be given
or taken by any Holder will be effective hereunder unless given or taken on or
prior to such expiration date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date (or their duly
appointed agents). On or prior to any expiration date set pursuant to this
paragraph, the Company may, on one or more occasions at its option, extend such
date to any later date. Nothing in this paragraph will prevent any Holder (or
any duly appointed agent thereof) from giving or taking, after any such
expiration date, any action identical to, or, at any time, contrary to or
different from, the action or purported action to which such expiration date
relates, in which event the Company may set a record date in respect thereof
pursuant to this paragraph. Nothing in this Section 13.11(e) will be construed
to render ineffective any action taken at any time by the Holders (or their duly
appointed agents) of the requisite principal amount of Outstanding Securities of
the relevant series on the date such action is so taken. Notwithstanding the
foregoing or the Trust Indenture Act, the Company will not set a record date
for, and the provisions of this Section 13.11(e) will not apply with respect to,
any notice, declaration, or direction referred to in the next paragraph.

            (f) Upon receipt by the Trustee from any Holder of Securities of a
particular series of (a) any notice of default or breach referred to in Section
8.01(a)(iv) or 8.01(a)(v) with respect to Securities of such series, if such
default or breach has occurred and is continuing and the Trustee shall not have
given such notice to the Company, (b) any declaration of acceleration referred
to in Section 8.01(b), if an Event of Default with respect to Securities of such
series has occurred and is continuing and the Trustee shall not have given such
a declaration to the Company, or (c) any direction referred to in Section 8.06
with respect to Securities of such series,

                                       58

<PAGE>

if the Trustee shall not have taken the action specified in such direction, then
a record date will automatically and without any action by the Company or the
Trustee be set for determining the Holders of Outstanding Securities of such
series entitled to join in such notice, declaration, or direction, which record
date will be the close of business on the tenth calendar day following the day
on which the Trustee receives such notice, declaration, or direction. Promptly
after such receipt by the Trustee, and in any case not later than the fifth
calendar day thereafter, the Trustee will notify the Company and the Holders of
Outstanding Securities of such series of any such record date so fixed. The
Holders of Outstanding Securities of such series on such record date (or their
duly appointed agents), and only such Persons, will be entitled to join in such
notice, declaration, or direction, whether or not such Holders remain Holders
after such record date; PROVIDED that, unless such notice, declaration, or
direction shall have become effective by virtue of Holders of the requisite
principal amount of Outstanding Securities of such series on such record date
(or their duly appointed agents) having joined therein on or prior to the 90th
calendar day after such record date, such notice, declaration, or direction will
automatically and without any action by any Person be cancelled and of no
further effect. Nothing in this Section 13.11(f) will be construed to prevent a
Holder (or a duly appointed agent thereof) from giving, before or after the
expiration of such 90-day period, a notice, declaration, or direction contrary
to or different from, or, after the expiration of such period, identical to, the
notice, declaration, or direction to which such record date relates, in which
event a new record date in respect thereof will be set pursuant to this Section
13.11(f). Nothing in this Section 13.11(f) will be construed to render
ineffective any notice, declaration, or direction of the type referred to in
this Section 13.11(f) given at any time to the Trustee and the Company by
Holders (or their duly appointed agents) of the requisite principal amount of
Outstanding Securities of the relevant series on the date such notice,
declaration, or direction is so given.

            (g) Without limiting the foregoing, a Holder entitled hereunder to
give or take any action hereunder with regard to any particular Security may do
so with regard to all or any part of the principal amount of such Security or by
one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any different part of such principal amount.

SECTION 13.12. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

            The Article and Section headings herein and the Table of Contents
are for convenience only and will not affect the construction hereof.

SECTION 13.13. BENEFITS OF INDENTURE.

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

    3.1  General.  The Plan will be administered by the Committee. The Committee will have full power and

ARTICLE 4. DURATION OF THE PLAN AND SHARES SUBJECT TO THE PLAN    
  

    4.1  Duration of the Plan.  The Plan is effective March 1, 1997, subject to approval by
Corporation's stockholders as provided in Article 15. The Plan will remain in effect until Awards have been granted covering all the available Shares and all outstanding Awards have been
exercised, settled, or terminated in accordance with the terms of the applicable Award Agreement, or the Plan is otherwise terminated by the Board. Termination of the Plan will not affect outstanding
Awards. 

    4.2  Other Stock Plans.  The Plan is separate from the following existing plans (the "Prior Plans"): 

Louisiana-Pacific
Corporation 1991 Employee Stock Option Plan;

Louisiana-Pacific Corporation 1984 Employee Stock Option Plan; and

Louisiana-Pacific Corporation Key Employee Restricted Stock Plan. 

2

 

The
Plan will neither affect the operation of the Prior Plans nor be affected by the Prior Plans, except that no further stock options or restricted stock awards will be granted under any of the Prior
Plans after the date the Plan is approved by Corporation's stockholders as described in Article 15. 

    4.3  General Limitation on Awards.  Subject to adjustment pursuant to Article 12 of the Plan, the
maximum number of Shares for which Awards may be granted under the Plan may not exceed 10,000,000 Shares. 

    4.4  Cancellation or Expiration of Awards.  If an Award under the Plan is canceled or expires for any
reason prior to having been fully vested or exercised by a Participant or is settled in cash in lieu of Shares or is exchanged for other Awards, all Shares covered by such Awards will again become
available for additional Awards under the Plan. 

 
 

ARTICLE 5. ELIGIBILITY    
  

    Officers and other key employees of Corporation and its Subsidiaries (including employees who may also be directors of Corporation or a Subsidiary) who, in the
Committee's judgment, are or will be contributors to the long-term success of Corporation will be eligible to receive Awards under the Plan. 

 
 

ARTICLE 6. AWARDS    
  

    6.1  Types of Awards.  Awards under the Plan may consist of: stock options (either incentive stock
options, within the meaning of Section 422 of the Code, or nonstatutory stock options), stock appreciation rights, performance shares, restricted stock grants, and other stock-based awards (as
described in Article 11 of the Plan). Awards of performance shares and restricted stock may provide the Participant with dividends or dividend equivalents and voting rights prior to vesting. 

    6.2  Award Agreements.  Each Award will be evidenced by a written Award Agreement between Corporation and
the Participant. Award Agreements may, subject to the provisions of the Plan, contain any provision approved by the Committee. Any Award Agreement may make provision for any matter that is within the
discretion of the Committee or may retain the Committee's discretion to approve or authorize any action with respect to the Award during the term of the Award Agreement. 

    6.3  Nonuniform Determinations.  The Committee's determinations under the Plan or under one or more Award
Agreements, including without limitation, (a) the selection of Participants to receive Awards, (b) the type, form, amount, and timing of Awards, (c) the terms of specific Award
Agreements, and
(d) elections and determinations made by the Committee with respect to exercise or payments of Awards, need not be uniform and may be made by the Committee selectively among Participants and
Awards, whether or not Participants are similarly situated. 

    6.4  Provisions Governing All Awards.  All Awards will be subject to the following provisions: 

    (a) Transferability. Except as otherwise provided in this Section 6.4(a), each Award (but not Shares issued
following Vesting or exercise of an Award) will not be transferable other than by will or the laws of descent and distribution and Awards requiring exercise will be exercisable during the lifetime of
the Participant only by the Participant or, in the event the Participant becomes legally incompetent, by the Participant's guardian or legal representative. Notwithstanding the foregoing, the
Committee, in its discretion, may include in any Award Agreement a provision that the Award is transferable, without payment of consideration, to immediate family members of the Participant or to a
trust for the benefit of or a partnership composed solely of such family members. 

    (b) Employment Rights. Neither the adoption of the Plan nor the granting of any Award will confer on any person the
right to continued employment with Corporation or any Subsidiary, nor will it interfere in any way with the right of Corporation or a Subsidiary to terminate such person's employment at any time for
any reason, with or without cause. 

3

 

    (c) Effect of Change in Control. The Committee may, in its discretion, include in any Award Agreement a provision that
upon the effective date of a change in control of Corporation (as that term may be defined in the Award Agreement), all or a specified portion of the Award (i) will become fully Vested,
(ii) will terminate, or (iii) may be converted into shares of an acquiror. In any such change in control provision, the Committee may provide whether or to what extent such acceleration
in the Vesting of an Award will be conditioned to avoid resulting in an "excess parachute payment" within the meaning of Section 280G(b) of the Code. 

 
 

ARTICLE 7. STOCK OPTIONS    
  

    The option price for each stock option may not be less than 100 percent of the Fair Market Value of the Common Stock on the date of grant. Stock options
will be exercisable for such period as specified by the Committee in the applicable Award Agreement, but in no event may options be exercisable for a period of more than ten years after their date of
grant. The option price of each Share as to which a stock option is exercised must be paid in full at the time of exercise. The Committee may, in its discretion, provide in any Award Agreement for a
stock option that payment of the option price may be made in cash, by tender of Shares owned by the Participant valued at Fair Market Value as of the
date of exercise, subject to such guidelines for the tender of Shares as the Committee may establish, in such other consideration as the Committee deems appropriate, or a combination of cash, shares
of Common Stock, and such other consideration. The number of Shares subject to options and stock appreciation rights granted under the Plan to any individual Participant during any
one-year period may not exceed 300,000 Shares. Except for adjustments in price pursuant to Article 12 hereof, at no time shall the option price of a stock option granted hereunder
be subsequently repriced during the period of its exercisability. 

    In
the case of an Option designated as an incentive stock option, the terms of the option and the Award Agreement must conform with the statutory and regulatory requirements specified
pursuant to Section 422 of the Code, as in effect on the date such incentive stock option is granted. 

    The
Committee may, in its discretion, include in an Award Agreement for any option a provision that in the event previously acquired Shares are surrendered by a Participant in payment
of all or a portion of either (a) the option exercise price or (b) the Participant's federal, state, or local tax withholding obligation with respect to such exercise, the Participant
will automatically be granted a replacement or reload option (with an option price equal to the Fair Market Value of a Share on the date of such exercise) for a number of Shares equal to all or a
portion of the number of Shares surrendered. Such replacement option will be subject to such terms and conditions as the Committee determines. 

 
 

ARTICLE 8. STOCK APPRECIATION RIGHTS    
  

    Stock appreciation rights may be granted in tandem with a stock option, in addition to a stock option, or may be freestanding and unrelated to a stock option.
Stock appreciation rights granted in tandem or in addition to a stock option may be granted either at the same time as the stock option or at a later time. No stock appreciation right may be
exercisable earlier than six months after grant, except in the event of the Participant's death or disability. A stock appreciation right will entitle the Participant to receive from Corporation an
amount equal to the increase in the Fair Market Value of a Share on the exercise of the stock appreciation right over the grant price. The Committee may determine in its discretion whether the stock
appreciation right may be settled in cash, shares, or a combination of cash and shares. 

4

 
 
 

ARTICLE 9. PERFORMANCE SHARES    
  

    9.1  General.  Performance shares may be granted in the form of actual Shares or Share units having a
value equal to Shares. An Award of performance shares will be granted to a Participant subject to such terms and conditions set forth in the Award Agreement as the Committee deems appropriate,
including, without limitation, the condition that the performance shares or a portion thereof will Vest only in the event specified performance goals are met within a specified performance period, as
set forth in the Award Agreement. An Award Agreement for a performance share Award may also, in addition to specifying performance goals, condition Vesting of such Award on continued employment for a
period specified in the Award Agreement. In the event that a stock certificate is issued in respect of performance shares, the certificate will be registered in the name of the Participant but will be
held by Corporation until the time the performance shares become Vested. The performance conditions and the length of the performance period will be determined by the Committee. The Committee may, in
its discretion, reduce or eliminate the Vesting of performance shares if, in the Committee's judgment, it determines that the Vesting of the performance share Award is not appropriate given actual
performance over the applicable performance period. The maximum number of Shares issuable to any individual Participant with respect to performance share Awards in any one-year period may
not exceed 100,000 Shares. The Committee, in its sole discretion, may provide in an Award Agreement whether performance shares granted in the form of share units will be paid in cash, shares, or a
combination of cash and shares. 

    9.2  Performance Goals for Executive Officers.  The performance goals for performance share awards
granted to executive officers of Corporation may relate to corporate performance, business unit performance, or a combination of both. 

    Corporate
performance goals will be based on financial performance goals related to the performance of Corporation as a whole and may include one or more measures related to earnings,
profitability, efficiency, or return to stockholders such as earnings per share, operating profit, stock price, costs of production, or other measures. 

    Business
unit performance goals will be based on a combination of financial goals and strategic goals related to the performance of an identified business unit for which a Participant
has responsibility. Strategic goals for a business unit may include one or a combination of objective factors relating to success in implementing strategic plans or initiatives, introductory products,
constructing facilities, or other identifiable objectives. Financial goals for a business unit may include the degree to which the business unit achieves one or more objective measures related to its
revenues, earnings, profitability, efficiency, operating profit, costs of production, or other measures. 

    Any
corporate or business unit goals may be expressed as absolute amounts or as ratios or percentages. Success may be measured against various standards, including budget targets,
improvement over prior periods, and performance relative to other companies, business units, or industry groups. 

 
 

ARTICLE 10. RESTRICTED STOCK    
  

    Restricted stock may be granted in the form of actual Shares or Share units having a value equal to Shares. A restricted stock Award will be subject to such
terms and conditions set forth in the Award Agreement as the Committee deems appropriate, including, without limitation, restrictions on the sale, assignment, transfer, or other disposition of such
restricted stock and provisions that such restricted stock or stock units be forfeited upon termination of the Participant's employment for specified reasons within a specified period of time or upon
other conditions, as set forth in the Award Agreement. The Award Agreement for a restricted stock Award may also, in addition to conditioning Vesting of the Award on continued employment, further
condition Vesting on attainment of performance goals. In the event that a stock certificate is issued in respect of restricted stock, such certificate will be registered in the name of the Participant
but will be held by the Corporation until the end of the restricted period. 

5

 

The employment conditions and the length of the period for vesting of restricted stock will be established by the Committee at the time of grant and set forth in the Award Agreement. The Committee, in
its sole discretion, may provide in an Award Agreement whether restricted stock granted in the form of Share units will be paid in cash, Shares, or a combination of cash and Shares. The aggregate
number of shares or share units that may be subject to restricted stock Awards may not exceed 1,000,000 Shares. 

 
 

ARTICLE 11. OTHER STOCK-BASED AND COMBINATION AWARDS    
  

    The Committee may grant other Awards under the Plan pursuant to which Shares are or may in the future be acquired, or Awards denominated in or measured by
Share equivalent units, including Awards valued using measures other than the market value of Shares. For such other stock-based awards that are granted to executive officers of Corporation and that
condition Vesting of such Awards, in whole or in part, on attaining performance goals, such Awards will be subject to the same limitations on types of performance goals and the same limitation on the
maximum number of Shares issuable to any individual Participant as provided in Article 9 of the Plan. The Committee may also grant Awards under the Plan in tandem or combination with other
Awards or in exchange for Awards, or in tandem or combination with, or as alternatives to, grants or rights under any other employee plan of Corporation. 

 
 

ARTICLE 12. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION    
  

    In the event of any change in capitalization affecting the Common Stock of Corporation, such as a stock dividend, stock split, recapitalization, merger,
consolidation, split-up, spinoff, combination or exchange of shares, or other form of reorganization, or corporate change, or any distribution with respect to Common Stock other than
regular cash dividends, the Committee may make such substitution or adjustment, if any, that it deems to be equitable as to the number and kind of Shares or other securities issued or reserved for
issuance pursuant to the Plan, to the limits on Awards to Participants, and to outstanding Awards. 

 
 

ARTICLE 13. AMENDMENT AND TERMINATION    
  

    The Board may amend, suspend, or terminate the Plan or any portion of the Plan at any time, provided no amendment may be made without stockholder approval if
such approval is required by applicable law or the requirements of an applicable stock exchange. 

 
 

ARTICLE 14. MISCELLANEOUS    
  

    14.1  Tax Withholding.  Corporation will have the right to deduct from any settlement of any Award under
the Plan, including the delivery or vesting of Shares, any federal, state, or local taxes of any kind required by law to be withheld with respect to such payments or to take such other action as may
be necessary in the opinion of Corporation to satisfy all obligations for the payment of such taxes. The recipient of any payment or distribution under the Plan must make arrangements satisfactory to
Corporation for the satisfaction of any such withholding tax obligations. Corporation will not be required to make any such payment or distribution under the Plan until such obligations are satisfied.
The Committee, in its discretion, may permit a Participant to satisfy the Participant's federal, state, or local tax, or tax withholding obligations with respect to an Award by having Corporation
retain the number of Shares having a Fair Market Value equal to the amount of taxes or withholding taxes. 

    14.2  Securities Law Restrictions.  No Shares will be issued under the Plan unless counsel for
Corporation is satisfied that such issuance will be in compliance with applicable federal and state securities laws. Certificates for Shares delivered under the Plan may be subject to such
stop-transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and 

6

 

other requirements of the Securities and Exchange Commission, any stock exchange upon which the Common Stock is then listed, and any applicable federal or state securities law. The Committee may cause
a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 

    14.3  Governing Law.  Except with respect to references to the Code or federal securities laws, the Plan
and all actions taken thereunder will be governed by and construed in accordance with the laws of the state of Oregon. 

 
 

ARTICLE 15. STOCKHOLDER APPROVAL    
  

    The adoption of the Plan and the grant of Awards under the Plan are expressly subject to the approval of the Plan by the affirmative vote of at least a
majority of the stockholders of Corporation present, or represented by proxy, and entitled to vote at Corporation's 1997 annual meeting of stockholders.
