Section 1.04 Acts of Holders; Record Dates.

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 shall 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 shall be sufficient for any purpose of this
Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

            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 shall also constitute sufficient proof
of his authority. The fact and date of 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.

            The ownership of Securities shall be proved by the Security
Register.

<PAGE>

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

            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, shall
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 shall 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 shall 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 paragraph shall 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 shall not set a record date
for, and the provisions of this paragraph shall not apply with respect to, any
notice, declaration or direction referred to in the next paragraph.

            The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.02, 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, (iii) any request to institute
proceedings referred to in Section 5.07(2) or (iv) any direction referred to in
Section 5.12, in each case with respect to Securities of such series. Promptly
after any record date is set pursuant to this paragraph, the Trustee shall
notify the Company and the Holders of Outstanding Series of such series of any
such record date so fixed and the proposed action. The Holders of Outstanding
Securities of such series on such record date (or their duly appointed agents),
and only such Persons, shall 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 day after such record date, such
notice, declaration or direction shall automatically and without any action by
any Person be cancelled and of no further effect. Nothing in this paragraph
shall 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 shall
be set pursuant to this paragraph. Nothing in this paragraph shall be construed
to render ineffective any notice, declaration or direction of the type referred
to in this paragraph 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.

            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 1.05 Notices, Etc., to Trustee and Company.

            Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with,

            (1) the Trustee by any Holder or by the Company shall be sufficient
      for every purpose hereunder if made, given, furnished or filed in writing
      (which may be via facsimile) to or with the Trustee at its Corporate Trust
      Office, Attention: Corporate Trust Department, or

            (2) the Company by the Trustee or by any Holder shall 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 the address of its principal office specified in the
      first paragraph of this instrument or at any other address previously
      furnished in writing to the Trustee by the Company.

Section 1.06 Notice to Holders; Waiver.

            Where this Indenture provides for notice to Holders of any event,
such notice shall 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 shall affect the
sufficiency of such notice with respect to other Holders. Where 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 shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

            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 shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

Section 1.07 Conflict with Trust Indenture Act.

            If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a

Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be. Wherever this Indenture refers to a provision of the Trust Indenture

hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

Section 1.13 Legal Holidays.

Securities (other than a provision of the Securities of any series which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) need not be made at such

Outstanding Securities, except that such Add On Securities:

                        (i) may have a different issue date from such series of
                  Outstanding Securities;

                        (ii) may have a different amount of interest payable on
                  the first Interest Payment Date after issuance than is payable
                  on such series of Outstanding Securities; and

                        (iii) may have terms specified in such Board Resolution
                  for such Add On Securities making appropriate adjustments to
                  this Article III applicable to such Add On Securities in order
                  to conform to and ensure compliance with the Securities Act
                  (or applicable securities laws) which are not adverse in any
                  material respect to the Holder of any Outstanding Securities
                  (other than such Add On Securities) and which shall not affect
                  the rights or duties of the Trustee.

Section 3.02 Denominations.

            The Securities of each series shall be issuable only in registered
form without coupons in such denominations as shall be specified as contemplated
by Section 3.01. In the absence of any such specified denomination with respect
to the Securities of any series, the Securities of such series shall be issuable
in denominations of $1,000 and any integral multiple thereof.

Section 3.03 Execution, Authentication, Delivery and Dating.

            The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its President, one of its
Vice Presidents or its Treasurer under its corporate seal reproduced thereon
attested by its Secretary or one of its Assistant Secretaries or by its Chief
Financial Officer. The signature of any of these officers on the Securities may
be manual or facsimile.

            Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall 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.

            At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities of any Series executed by
the Company to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Sections 2.01 and 3.01, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be
fully protected in relying upon, an Opinion of Counsel stating,

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

<PAGE>

            (2) if the terms of such Securities have been established by or
      pursuant to Board Resolution as permitted by Section 3.01, that such terms
      have been established in conformity with the provisions of this Indenture;
      and

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

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

            Notwithstanding the provisions of Section 3.01 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.01 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph 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.

            Each Security shall be dated the date of its authentication.

            No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has 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 3.09, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

Section 3.04 Temporary Securities.

            Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

            If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
a like aggregate principal amount and tenor. Until so exchanged the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

Section 3.05 Registration, Registration of Transfer and Exchange.

            The Company shall cause to be kept at the Corporate Trust Office of
the Trustee 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

<PAGE>

as it may prescribe, the Company shall 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.

            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 shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of a like aggregate
principal amount and tenor.

            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 shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

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

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

            No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company or Security Registrar 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 3.04, 9.06 or 11.07 not
involving any transfer.

            The Company shall not be required (1) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under Section
11.03 and ending at the close of business on the day of such mailing, or (2) to
register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

            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
(1) such Depositary (A) notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security or (B) has ceased to be a
clearing agency registered under the Exchange Act, (2) 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, (3) there shall have occurred and be continuing an Event of Default
with respect to the Securities evidenced by such Global Security or (4) there
shall exist such other circumstances, if any, as have been specified for this
purpose as contemplated by Section 3.01. 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 the preceding paragraph shall
apply, whether pursuant to this Section, Section 3.04, 3.06, 9.06 or 11.07 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security.

Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

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

            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 shall execute and the Trustee shall 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.

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

            Upon the issuance of any new Security under this Section, 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.

            Every new Security of any series issued pursuant to this Section in
exchange for any mutilated Security or in lieu of any destroyed, lost or stolen
Security shall 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 shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
of that series duly issued hereunder.

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

Section 3.07 Payment of Interest; Interest Rights Preserved.

            Except as otherwise provided as contemplated by Section 3.01 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 shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

            Any interest on any Security of any series which is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

            (1) The Company may elect to make payment of any Defaulted Interest
      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
      shall be fixed in the following manner. The Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each Security of such series and the date of the proposed payment, and
      at the same time the Company shall deposit with the Trustee an amount of
      money equal to the aggregate amount proposed to be paid in respect of such
      Defaulted Interest or shall make arrangements satisfactory to the Trustee
      for such deposit prior to the date of the proposed payment, such money
      when deposited to be held in trust for the benefit of the Persons entitled
      to such Defaulted Interest as in this Clause provided. Thereupon the
      Trustee shall fix a Special Record Date for the payment of such Defaulted
      Interest which shall be not more than 15 days and not less than 10 days
      prior to the date of the proposed payment and not less than 10 days after
      the receipt by the Trustee of the notice of the proposed payment. The
      Trustee shall promptly notify the Company of such Special Record Date and,
      in the name and at the expense of the Company, shall cause notice of the
      proposed payment of such Defaulted Interest and the Special Record Date
      therefor to be mailed, first-class

<PAGE>

      postage prepaid, to each Holder of Securities of such series at his
      address as it appears in the Security Register, not less than 10 days
      prior to such Special Record Date. Notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor having been so
      mailed, such Defaulted Interest shall be paid to the Persons in whose
      names the Securities of such series (or their respective Predecessor
      Securities) are registered at the close of business on such Special Record
      Date and shall no longer be payable pursuant to the following Clause (2).

            (2) The Company may make payment of any Defaulted Interest 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, such manner of payment shall be deemed
      practicable by the Trustee.

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

Section 3.08 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 3.07) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

Section 3.09 Cancellation.

            All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall 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 shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture. All cancelled
Securities held by the Trustee shall be disposed of by the Trustee in its
customary manner.

Section 3.10 Computation of Interest.

            Except as otherwise specified as contemplated by Section 3.01 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

Section 3.11 CUSIP Numbers.

            The Company in issuing the Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; 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 shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any changes in the "CUSIP" numbers.

                          SATISFACTION AND DISCHARGE

Section 4.01 Satisfaction and Discharge of Indenture.

            This Indenture shall upon 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 of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

            (1) either

                  (A) all Securities theretofore authenticated and delivered
            (other than (i) Securities which have been destroyed, lost or stolen
            and which have been replaced or paid as provided in Section 3.06 and
            (ii) Securities for whose payment 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)
            have been delivered to the Trustee for cancellation; or

                  (B) all such Securities not theretofore delivered to the
            Trustee for cancellation

                        (i) have become due and payable, or

                        (ii) will become due and payable at their Stated
                  Maturity within one year, or

                        (iii) 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 (i),
                  (ii) or (iii) above, has deposited or caused to be deposited
                  with the Trustee as trust funds in trust for the 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;

            (2) the Company has paid or caused to be paid all other sums payable
      hereunder by the Company; and

            (3) the Company has delivered to the Trustee an Officers'
      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 complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.07, and, if money
shall have been deposited with the Trustee pursuant to subclause (B) of Clause
(1) of this Section, the obligations of the Trustee under Section 4.02 shall
survive such satisfaction and discharge.

Section 4.02 Application of Trust Money.

            All money deposited with the Trustee pursuant to Section 4.01 shall
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 whose payment such money has been deposited with the
Trustee.

      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

      proceeding under any applicable Federal or State bankruptcy, insolvency,

      corporate action by the Company in furtherance of any such action; or

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

<PAGE>

Section 5.02 Acceleration of Maturity; Rescission and Annulment.

            If an Event of Default with respect to Securities of any series at
the time Outstanding occurs and is continuing, then in every such 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) shall become immediately due and payable.

            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 due has been obtained by the Trustee as hereinafter in this
Article 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

            (1) 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, its agents and counsel; and

            (2) 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 5.13.

            No such rescission shall affect any subsequent default or impair any
right consequent thereon.

Section 5.03 Collection of Indebtedness and Suits for Enforcement by Trustee.

            The Company covenants that if:

            (1) 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 days, or

            (2) default is made in the payment of the principal of (or premium,
      if any, on) any Security at the Maturity thereof,

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 shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

            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
necessary to protect and enforce any such rights,

<PAGE>

whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

Section 5.04 Trustee May File Proofs of Claim.

            In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall 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 shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07.

            No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

Section 5.05 Trustee May Enforce Claims Without Possession of Securities.

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

Section 5.06 Application of Money Collected.

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:

      and payable on such Securities for principal and any premium and interest,
      respectively; and

            THIRD: To the Company.

Section 5.07 Limitation on Suits.

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

            (1) such Holder has previously given written notice to the Trustee
      of a continuing Event of Default with respect to the Securities of that
      series;

<PAGE>

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

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

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

            (5) no direction inconsistent with such written request has been
      given to the Trustee during such 60-day period by the Holders of a
      majority in principal amount of the Outstanding Securities of that series;
      it being understood and intended that no one or more of such Holders shall
      have any right in any manner whatever by virtue of, or by availing of, any
      provision of this Indenture to affect, disturb or prejudice the rights of
      any other of such Holders, or to obtain or to seek to obtain priority or
      preference over any other of such Holders or to enforce any right under
      this Indenture, except in the manner herein provided and for the equal and
      ratable benefit of all of such Holders.

Section 5.08 Unconditional Right of Holders to Receive Principal, Premium and
Interest.

            Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Section
3.07) interest on such Security on the respective Stated Maturities expressed in
such Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

Section 5.09 Restoration of Rights and Remedies.

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

Section 5.10 Rights and Remedies Cumulative.

            Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 3.06, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

Section 5.11 Delay or Omission Not Waiver.

            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
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein. Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders,
as the case may be.

<PAGE>

Section 5.12 Control by Holders.

            The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that

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

            (2) the Trustee may take any other action deemed proper by the
      Trustee which is not inconsistent with such direction, and

            (3) subject to the provisions of Section 6.01, the Trustee shall
      have the right to decline to follow any such direction if the Trustee in
      good faith share, by a Responsible Officer or Officers of the Trustee,
      determine, and the Trustee shall have received a legal opinion stating,
      that the proceedings so directed would involve the Trustee in personal
      liability.

Section 5.13 Waiver of Past Defaults.

            The Holders of not less than 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

            (1) in the payment of the principal of or any premium or interest on
      any Security of such series, or

            (2) in respect of a covenant or provision hereof which under Article
      IX 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 shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

Section 5.14 Undertaking for Costs.

            In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act
shall apply to any suit instituted by the Trustee, to any suit instituted by any
Holders of the Securities, or group of Holders of the Securities, holding in the
aggregate more than 10% of principal amount of the Outstanding Securities of any
series, or to any suit instituted by any Holder of the Outstanding Securities
for the enforcement of the payment of principal of or interest on any
Outstanding Securities held by such Holder, on or after the respective due dates
expressed in such Outstanding Securities, and provided, further, that neither
this Section nor the Trust Indenture Act shall be deemed to authorize any court
to require such an undertaking or to make such an assessment in any suit
instituted by the Company.

Section 5.15 Waiver of Usury, Stay or Extension Laws.

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

                                   ARTICLE VI

                                   THE TRUSTEE

            The Trustee hereby accepts the trust imposed upon it by this
Indenture and covenants and agrees to perform the same, as herein expressed.

Section 6.01 Duties of Trustee.

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

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

            (1) The Trustee need perform only those duties as are specifically
      set forth in this Indenture and no others, and no covenants or obligations
      shall be implied in or read into this Indenture.

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

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

            (1) This paragraph does not limit the effect of paragraph (b) of
      this Section 6.01.

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

            (3) The Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 5.12.

            (d) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture.

            (e) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c), (d) and (f) of this Section
6.01.

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

Section 6.02 Rights of Trustee.

            Subject to Section 6.01:

            (a) The Trustee may conclusively rely on any document (whether in
its original or facsimile form) believed by it to be genuine and to have been
signed or presented by the proper person. The Trustee need not investigate any
fact or matter stated in any document.

<PAGE>

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

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

            (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers.

            (e) The Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, notice, request, direction, consent, order, bond,
debenture, or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may
see fit and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney at the sole cost of the
Company and shall incur no liability or additional liability of any kind by
reason of such investigation.

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

            (g) the Trustee may consult with counsel of its selection and the
advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection of any action taken, suffered or omitted by in
hereunder in good faith and in reliance thereon. (h) the Trustee shall not be
deemed to have notice of any Event of Default unless a Responsible Officer of
the Trustee has actual knowledge thereof or unless written notice of any event
which is in fact such a default is received by the Trustee at the Corporate
Trust Office of the Trustee, and such notice references the Securities and this
Indenture.

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

Section 6.03 Individual Rights of Trustee.

            The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company, its
Subsidiaries, or their respective Affiliates with the same rights it would have
if it were not Trustee. Any Paying Agent or Security Registrar may do the same
with like rights. However, the Trustee must comply with Sections 6.08, 6.09 and
6.10.

Section 6.04 Trustee's Disclaimer.

            The Trustee makes no representation as to the validity or adequacy
of this Indenture or the Securities and it shall not be accountable for the
Company's use of the proceeds from the Securities, and it shall not be
responsible for any statement in the Securities, other than the Trustee's
certificate of authentication, or the use or application of any funds received
by a Paying Agent other than the Trustee.

Section 6.05 Notice of Default.

            If an Event of Default with respect to Securities of any series
occurs and is continuing and if it is known to the Trustee, the Trustee shall
mail to each Holder of Securities of such series notice of the uncured Event of
Default within 90 days after such Event of Default occurs. Except in the case of
an Event of Default in payment of principal (or premium, if any) of, or interest
on, any Security, the Trustee may withhold the notice if and so long as a

<PAGE>

Responsible Officer in good faith determines that withholding the notice is in
the interest of the Holders of Securities of such series.

Section 6.06 Reports by Trustee to Holders.

            Within 60 days after each February 15 beginning with the February 15
following the date of this Indenture, the Trustee shall mail to each Holder a
brief report dated as of such February 15 that complies with Trust Indenture Act
Section 313(a) if such report is required by such Trust Indenture Act Section
313(a). The Trustee also shall comply with Trust Indenture Act Sections 313(b)
and 313(c).

            The Company shall promptly notify the Trustee in writing if the
Securities of any series become listed on any stock exchange or automatic
quotation system.

            A copy of each report at the time of its mailing to Holders shall be
mailed to the Company and filed with the Commission and each stock exchange, if
any, on which the Securities are listed.

Section 6.07 Compensation and Indemnity.

            The Company shall pay to the Trustee from time to time such
compensation for its services as the Company and the Trustee shall from time to
time agree in writing. The Trustee's compensation shall not be limited by any
law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable disbursements, expenses
and advances incurred or made by it. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents, accountants,
experts and counsel.

            The Company shall indemnify each of the Trustee (in its capacity as
Trustee) and any predecessor Trustee and each of their respective officers,
directors, attorneys-in-fact and agents for, and hold it harmless against, any
claim, demand, expense (including but not limited to reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel), loss, charges
(including taxes (other than taxes based upon the income of the Trustee)) or
liability incurred by them without negligence or bad faith on its part, arising
out of or in connection with the acceptance or administration of this trust and
their rights or duties hereunder including the reasonable costs and expenses of
defending themselves against any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder. The Trustee
shall notify the Company promptly of any claim asserted against the Trustee for
which it may seek indemnity. The Company shall defend the claim and the Trustee
shall provide reasonable cooperation at the Company's expense in the defense.
The Trustee may have separate counsel and the Company shall pay the reasonable
fees and expenses of such counsel. The Company need not pay for any settlement
made without its written consent which consent shall not be unreasonably
withheld. The Company need not reimburse any expense or indemnify against any
loss or liability to the extent incurred by the Trustee as determined by a court
of competent jurisdiction to have been caused by its own negligence, bad faith
or willful misconduct.

            To secure the Company's payment obligations in this Section 6.07,
the Trustee shall have a lien prior to the Securities on all assets held or
collected by the Trustee, in its capacity as Trustee, except assets held in
trust to pay principal and premium, if any, of or interest on particular
Securities.

            When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 5.01(6) or (7) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

            The Company's obligations under this Section 6.07 and any lien
arising hereunder shall survive the resignation or removal of the Trustee, the
discharge of the Company's obligations pursuant to Article IV of this Indenture
and any rejection or termination of this Indenture under any Bankruptcy Law.

Section 6.08 Replacement of Trustee.

            The Trustee may resign at any time with respect to the Securities of
one or more series by so notifying the Company in writing. The Holder or Holders
of a majority in principal amount of the outstanding

<PAGE>

Securities of a series may remove the Trustee with respect to Securities of such
series by so notifying the Company and the Trustee in writing and may appoint a
successor trustee with respect to Securities of such series with the Company's
consent. The Company may remove the Trustee if:

            (1) the Trustee fails to comply with Section 6.10;

            (2) the Trustee is adjudged bankrupt or insolvent;

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

            (4) the Trustee becomes incapable of acting.

            If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee, with respect to the Securities of one or more series, for any
reason, the Company shall promptly appoint a successor Trustee, with respect to
Securities of that or those series. Within one year after the successor Trustee
with respect to a series of Securities takes office, the Holder or Holders of a
majority in principal amount of the Securities of such series may appoint a
successor Trustee with respect to such series to replace the successor Trustee
appointed by the Company.

            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that
and provided that all sums owing to the Trustee provided for in Section 6.07
have been paid, the retiring Trustee shall transfer all property held by it as
Trustee with respect to such series of Securities to the successor Trustee,
subject to the lien provided in Section 6.07, the resignation or removal of the
retiring Trustee shall become effective, and the successor Trustee shall have
all the rights, powers and duties of the Trustee under this Indenture. A
successor Trustee with respect to one or more series of Securities shall mail
notice of its succession to each Holder of Securities of that or those series.

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

            If the Trustee fails to comply with Section 6.10, any Holder of
Securities of a series may petition any court of competent jurisdiction for the
removal of the Trustee with respect to such series and the appointment of a
successor Trustee with respect to such series.

            Notwithstanding replacement of the Trustee pursuant to this Section
6.08, the Company's obligations under Section 6.07 shall continue for the
benefit of the retiring Trustee.

Section 6.09 Successor Trustee by Merger, Etc.

            If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee.

Section 6.10 Eligibility; Disqualification.

            The Trustee shall at all times satisfy the requirements of Trust
Indenture Act Section 310(a)(1) and Trust Indenture Act Section 310(a)(5). The
Trustee shall have a combined capital and surplus of at least $50,000,000 as set
forth in its most recent published annual report of condition. The Trustee shall
comply with Trust Indenture Act Section 310(b).

            (2) at such other times as the Trustee may request in writing,
      within 30 days after the receipt by the Company of any such request, a
      list of similar form and content as of a date not more than 15 days prior
      to the time such list is furnished; excluding from any such list names and
      addresses received by the Trustee in its capacity as Security Registrar.

            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, shall be as provided by the
Trust Indenture Act.

            Every Holder of Securities, by receiving and holding the same,

            A copy of each such report shall, at the time of such transmission

Securities are listed, with the Commission and with the Company. The Company
will notify the Trustee when any Securities are listed on any stock exchange or
delisted therefrom.

Section 7.04 Reports by Company.

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

pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 shall be
filed with the Trustee within 15 days after the same is so required to be filed
with the

<PAGE>

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

            The Company may not, in a single transaction or through a series of
related transactions, consolidate with or merge with or into any other person,
or, directly or indirectly, sell, lease, assign, transfer or convey its
properties and assets as an entirety or substantially as an entirety (computed
on a consolidated basis) to another person or group of affiliated persons, and
another person or group of affiliated persons may not directly or indirectly
sell, lease, assign, transfer or convey its properties and assets as an entity
or substantially as an entity (computed on a consolidated basis) to the Company,
unless:

            (1) the Company shall be the continuing person, or 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 as an entirety or substantially
      as an entirety (the Company or such other person being hereinafter
      referred to as the "Surviving Person"), and shall expressly assume, by an
      indenture supplemental hereto, executed and delivered to the Trustee, in
      form and substance satisfactory to the Trustee, all the obligations of the
      Company under the Securities and this Indenture and the Indenture, so
      supplemented, shall remain in full force and effect;

            (2) immediately after giving effect to such transaction and the
      assumption of the obligations as set forth in clause (1), above, no Event
      of Default shall have occurred and be continuing; and

            (3) if a supplemental indenture is required in connection with such
      transaction, the Company has delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that such
      consolidation, merger, assignment, or transfer and such supplemental
      indenture comply with this Article VIII and that all conditions precedent
      herein provided relating to such transaction have been satisfied.

Section 8.02 Successor Corporation Substituted.

            Upon any consolidation or merger, or any transfer of assets in
accordance with Section 8.01, the Surviving Person formed by such consolidation
or into which the Company is merged or to which such transfer is made shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under this Indenture with the same effect as if such Surviving
Person had been named as the Company herein. When a Surviving Person duly
assumes all of the obligations of the Company pursuant hereto and pursuant to
the Securities, the predecessor shall be relieved of the performance and
observance of all obligations and covenants of this Indenture and the
Securities, including but not limited to the obligation to make payment of the
principal of and interest, if any, on all the Securities then outstanding, and
the Company may thereupon or any time thereafter be liquidated and dissolved.

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

      any such addition, change or elimination (A) shall neither (i) 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
      (ii) modify the rights of the Holder of any such Security with respect to
      such provision or (B) shall become effective only when there is no such
      Security Outstanding; or

            (6) to secure the Securities pursuant to the requirements of Article

      hereunder by a successor Trustee with respect to the Securities of one or
      more series and to add to or change any of the provisions of this
      Indenture as shall be necessary to provide for or facilitate the
      administration of the trusts hereunder by more than one Trustee, pursuant
      to the requirements of Section 6.11; or

            (9) 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 (9) shall not adversely affect the interests of the Holders
      of Securities of any series in any material respect.

Section 9.02 Supplemental Indentures with Consent of Holders.

            With the consent of the Holders of not less than 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 shall, without the consent of the Holder of
each Outstanding Security affected thereby,

            (1) change the Stated Maturity of the principal of, or any
      installment of principal of or interest on, any Security, or reduce the

      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 5.02, or change any Place of Payment
      where, or the coin or currency in which, any Security or any premium or
      interest thereon is payable, or impair the right to institute suit for the
      enforcement of any such payment on or after the Stated Maturity thereof
      (or, in the case of redemption, on or after the Redemption Date), or

<PAGE>

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

            (3) modify any of the provisions of this Section or Section 5.13,
      except to increase any such percentage or to provide that certain other

      provided, however, that this clause shall not be deemed to require the
      consent of any Holder with respect to changes in the references to "the
      Trustee" and concomitant changes in this Section, or the deletion of this
      proviso, in accordance with the requirements of Sections 6.11 and 9.01(8),

            (4) change any obligation of ours to maintain an office or agency,
      or

            (5) change any obligation of ours to pay additional amounts, or

      option of the Holder, or

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

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

Section 9.03 Execution of Supplemental Indentures.

            In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 6.01) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is

obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

Section 9.04 Effect of Supplemental Indentures.

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

conform to the requirements of the Trust Indenture Act.

Section 9.06 Reference in Securities to Supplemental Indentures.

execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as

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

<PAGE>

may be prepared and executed by the Company and authenticated and delivered by
the Trustee in exchange for Outstanding Securities of such series.

                                   ARTICLE X

                                   COVENANTS

Section 10.01 Covenants.

            Any covenants applicable to any series of Securities shall be

                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

Section 11.01 Applicability of Article.

            Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 3.01 for Securities of any
series) in accordance with this Article.

Section 11.02 Election to Redeem; Notice to Trustee.

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

Section 11.03 Selection by Trustee of Securities to Be Redeemed.

            If less than all the Securities of any series are to be redeemed
(unless all of the Securities of such series and of a specified tenor are to be
redeemed), the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall 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 for Securities of that series. If less than
all of the Securities of such series and of a specified tenor are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series and specified tenor not previously called for
redemption in accordance with the preceding sentence.

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

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

<PAGE>

Section 11.04 Notice of Redemption.

            Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 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 shall state:

            (1) the Redemption Date,

            (2) the Redemption Price,

            (3) 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,

            (4) 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,

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

            (6) that the redemption is for a sinking fund, if such is the case,
      and

            (7) applicable CUSIP Numbers.

            Notice of redemption of Securities to be redeemed at the election of
the Company shall 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 shall be irrevocable.

Section 11.05 Deposit of Redemption Price.

            Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent an amount of money sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on, all the Securities which are to be redeemed
on that date.

Section 11.06 Securities Payable on Redemption Date.

            Notice of redemption having been given as aforesaid, the Securities
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 3.01, installments of interest whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 3.07.

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

<PAGE>

Section 11.07 Securities Redeemed in Part.

Any Security which is to be redeemed only in part shall 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 shall execute, and the Trustee
shall 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 XII

                                 SINKING FUNDS

Section 12.01 Applicability of Article.

            The provisions of this Article shall be applicable to any sinking
fund for the retirement of Securities of a series except as otherwise specified
as contemplated by Section 3.01 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 cash amount of any sinking fund payment may be subject to reduction as
provided in Section 12.02. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

Section 12.02 Satisfaction of Sinking Fund Payments with Securities.

            The Company (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (2) 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 shall 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 shall be reduced
accordingly.

Section 12.03 Redemption of Securities for Sinking Fund.

            Not less than 60 days prior to each sinking fund payment date for
any series of Securities, the Company will deliver to the Trustee an Officers'
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,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 12.02 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 11.03 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 11.04. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 11.06 and 11.07.

                                  ARTICLE XIII

             REDEMPTION UPON A DESIGNATED EVENT AND A RATING DECLINE

Section 13.01 Redemption by Holders.

            Subject to Section 3.01(14), in the event that there occurs (a) a
Designated Event (as hereinafter defined) at any time on or prior to Maturity,
and (b) a Rating Decline (as hereinafter defined), each Holder of a Security
that is of a series to which this Article XIII is applicable (for purposes of
this Article XIII, a "Subject Security") shall have the right, at the Holder's
option, to require the Company to redeem all or any portion (which shall be
$1,000 or an integral multiple thereof) of such Subject Security on the date
that is 90 days after the last to occur of public notice of the occurrence of
the Designated Event and the Rating Decline, at a redemption price equal to 100%
of the principal amount thereof, plus accrued interest to the Redemption Date.

            On or before the twenty-eighth day after the last to occur of public
notice of the occurrence of the Designated Event and the Rating Decline, the
Company is obligated to notify the Trustee of such events, and promptly
thereafter to mail, or cause to be mailed first-class, postage prepaid, to each
Holder of any Subject Securities, at the address of such Holder appearing in the
Security Register, a notice regarding the Designated Event, the Rating Decline,
and the redemption right. The notice shall include the Redemption Date, the date
by which the redemption right must be exercised, the Redemption Price, and the
procedure which the Holder must follow to exercise this right.

            To exercise this right, the Holder of such Subject Securities must
deliver on or before a date selected by the Company, which date shall be not
more than 10 days prior to the Redemption Date, written notice to the Company
(or an agent designated by the Company for such purpose) of the Holder's
exercise of such right, together with the Subject Securities with respect to
which the right is being exercised, duly endorsed or assigned to the Company or
in blank. Such written notice by a Holder shall, unless otherwise required by
law, be irrevocable.

            As used herein, a "Designated Event" shall be deemed to have
occurred at such a time as any "person" or "group" (as such terms are used for
purposes of Sections 13(d) and 14(d) of the Exchange Act, whether or not
applicable) becomes the "beneficial owner" (as the term is used in Rules 13d-3
and 13d-5 under the Exchange Act, whether or not applicable, except that a
person shall be deemed to have "beneficial ownership" of all shares that any
such person has the right to acquire, whether such right is exercisable
immediately or only after the passage of time), directly or indirectly, of more
than 50% of the total voting power entitled to vote in the election of directors
of the Company; provided, however, that a Designated Event shall not be deemed
to have occurred (i) as a result of the formation of such a "group" or the
acquisition of shares of Capital Stock of the Company by such group if such
group includes existing Affiliates and/or persons who beneficially own in the
aggregate, as of the date of this Indenture, 20% or more of the outstanding
shares of Capital Stock of the Company on the date of this Indenture, or (ii) by
virtue of the Company, any Subsidiary, any employee stock ownership plan or any
other employee benefit plan of the Company or any Subsidiary, or any other
person holding Capital Stock of the Company for or pursuant to the terms of any
such employee benefit plan, becoming a beneficial owner, directly or indirectly,
of more than 50% of the total voting power entitled to vote in the election of
directors of the Company.

            As used herein, a "Rating Decline" shall be deemed to have occurred
if on any date within the 90-day period following public notice of the
occurrence of a Designated Event (which 90-day period shall be extended with
respect to either Rating Agency (as hereinafter defined) for so long as the
rating of the Securities is under publicly announced consideration for possible
downgrade relating to such Designated Event by such Rating Agency) (i) in the
event the Securities are rated by one Rating Agency or by both Rating Agencies
on the Rating Date (as hereinafter defined) as Investment Grade (as hereinafter
defined), the rating of the Securities by such Rating Agency or by either of
such Rating Agencies (as the case may be) shall be below Investment Grade; or
(ii) in the event the Securities are rated by both Rating Agencies on the Rating
Date below Investment Grade, the rating of the Securities by either Rating
Agency shall be at least one Full Rating Category (as hereinafter defined) below
the rating of the Securities by such Rating Agency on the Rating Date.

<PAGE>

            As used herein, "Rating Agency" shall mean Standard & Poor's
Corporation and its successors ("S&P"), and Moody's Investors Service and its
successors ("Moody's"), or if S&P or Moody's or both shall not make a rating on
the Securities publicly available, a nationally recognized statistical rating
organization or organizations, as the case may be, selected by the Company which
shall be substituted for S&P or Moody's or both, as the case may be; "Investment
Grade" shall mean BBB- or higher by S&P or Baa3 or higher by Moody's or the
equivalent of such ratings by S&P or Moody's or by any other Rating Agency
selected as provided above, and "Rating Date" shall mean the date which is 121
days prior to public notice of the occurrence of a Designated Event.

            As used herein, the term, "Full Rating Category" shall mean (i) with
respect to S&P, any of the following categories BB, B, CCC, CC, and C; (ii) with
respect to Moody's, any of the following categories: Ba, B, Caa, Ca, and C; and
(iii) with respect to any other Rating Agency, the equivalent of any such
category of S&P or Moody's used by such other Rating Agency. In determining
whether the rating of the Securities has decreased by the equivalent of one Full
Rating Category, gradation within Full Rating Categories (+ and - for S&P, 1, 2,
and 3 for Moody's; or the equivalent gradation for another Rating Agency) shall
be taken into account (e.g., with respect to S&P, a decline in a rating from BB+
to BB-, or from BB to B+, will constitute a decrease of less than one Full
Rating Category).

Section 13.02 Redemption by Company.

            In the event the aggregate principal amount of the Subject
Securities that are surrendered for redemption on any such Redemption Date is a
least 90% of the aggregate principal amount of the Subject Securities
Outstanding at the close of business on the day next preceding such Redemption
Date, the remaining Subject Securities not so redeemed will be subject to
redemption as a whole, at the Company's option, upon not less than 30 days'
notice mailed to each Holder at the address of such Holder appearing in the
Security Register, on a date of redemption selected by the Company that is
within 60 days after such Redemption Date, at a Redemption Price equal to 100%
of the principal amount, plus accrued interest to such date of redemption
selected by the Company.

Section 13.03 Other Provisions.

            With respect to any redemption at the option of the Holders of
Securities, as hereinabove provided, (x) the first clause of Section 11.06 shall
read as follows: "Notice by the Holder of such Holder's exercise of the
redemption right having been duly given," and (y) if any Security delivered by
the Holder upon exercise of the redemption right is, at the option of the
Holder, to be redeemed in part only, the written notice delivered by the Holder
to the Company as aforesaid shall state the principal amount of the Security
which is to be redeemed.

            Notwithstanding the foregoing, the Holders shall not have the
redemption right described above if, prior to the occurrence of the Designated
Event, the Company has effected a defeasance or covenant defeasance of the
Securities as provided in Article XIV.

                                  ARTICLE XIV

                       DEFEASANCE AND COVENANT DEFEASANCE

Section 14.01 Company's Option to Effect Defeasance or Covenant Defeasance.

            The Company may elect, at its option by Board Resolution at any
time, to have either Section 14.02 or Section 14.03 applied to the Outstanding
Securities of any series designated pursuant to Section 3.01 as being defeasible
pursuant to this Article XIV (hereinafter called a "Defeasible Series"), upon
compliance with the conditions set forth below in this Article XIV.

Section 14.02 Defeasance and Discharge.

            Upon the Company's exercise of the option provided in Section 14.01
to have this Section 14.02 applied to the Outstanding Securities of any
Defeasible Series and subject to the proviso to Section 14.01, the Company shall
be deemed to have been discharged from its obligations with respect to the
Outstanding Securities of

<PAGE>

such series as provided in this Section on and after the date the conditions set
forth in Section 14.04 are satisfied (hereinafter called "Defeasance"). For this
purpose, such Defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by 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, shall execute proper
instruments acknowledging the same), subject to the following which shall
survive until otherwise terminated or discharged hereunder: (1) the rights of
Holders of Securities of such series to receive, solely from the trust fund
described in Section 14.04 and as more fully set forth in such Section, payments
in respect of the principal of and any premium and interest on such Securities
of such series when payments are due, (2) the Company's obligations with respect
to the Securities of such series under Sections 3.04, 3.05, 3.06, [the covenant
requiring the Company to maintain an office or agency for the payment of
Securities] and [the covenant requiring the Company to hold in trust funds for
the payment of Securities], (3) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (4) this Article XIV. Subject to
compliance with this Article XIV, the Company may exercise its option provided
in Section 14.01 to have this Section 14.02 applied to the Outstanding
Securities of any Defeasible Series notwithstanding the prior exercise of its
option provided in Section 14.01 to have Section 14.03 applied to the
Outstanding Securities of such series.

Section 14.03 Covenant Defeasance.

            Upon the Company's exercise of the option provided in Section 14.01
to have this Section 14.03 applied to the Outstanding Securities of any
Defeasible Series, (1) the Company shall be released from its obligations under
Section 8.01, and [the covenants requiring the Company to maintain its corporate
existence and to satisfy its tax obligations and certain other claims, and any
negative covenants applicable to the Securities], and Article XIII, and (2) the
occurrence of any event specified in Sections 5.01(3), 5.01(4) (with respect to
Section 8.01, [the covenants requiring the Company to maintain its corporate
existence and to satisfy its tax obligations and certain other claims, and any
negative covenants applicable to the Securities] and Article XIII), 5.01(5) and
5.01(8) shall 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 in Section 14.04 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such specified Section (to the extent so specified in the case of Section
5.01(4)), whether directly or indirectly by reason of any reference elsewhere
herein to any such Section or by reason of any reference in any such Section to
any other provision herein or in any other document, but the remainder of this
Indenture and the Securities of such series shall be unaffected thereby.

Section 14.04 Conditions to Defeasance or Covenant Defeasance.

            The following shall be the conditions to application of either
Section 14.02 or Section 14.03 to the Outstanding Securities of any Defeasible
Series:

            (1) The Company shall irrevocably have deposited or caused to be
      deposited with the Trustee (or another trustee that satisfies the
      requirements contemplated by Section 6.09 and agrees to comply with the
      provisions of this Article XIV applicable to it) as trust funds in trust
      for the purpose of making the following payments, specifically pledged as
      security for, and dedicated solely to, the benefit of the Holders of
      Outstanding Securities of such series, (A) money in an amount, or (B) U.S.
      Government Obligations that through the scheduled payment of principal and
      interest in respect thereof in accordance with their terms will provide,
      not later than one day before the due date of any payment, money in an
      amount, or (C) a combination thereof, in each case sufficient, in the
      opinion of a nationally recognized firm of independent public accountants
      expressed in a written certification thereof delivered to the Trustee, to
      pay and discharge, and which shall be applied by the Trustee (or any such
      other qualifying trustee) to pay and discharge, the principal of and any
      premium and interest on the Securities of such series on the respective
      Stated Maturities, in accordance with the terms of this Indenture and the
      Securities of such series. As used herein, "U.S. Government Obligation"
      means (x) any security that is (i) a direct obligation of the United
      States of America for the payment of which full faith and credit of the
      United States of America is pledged or (ii) an obligation of a Person
      controlled or supervised by and acting as an agency or instrumentality of
      the United States of

<PAGE>

      America the payment of which is unconditionally guaranteed as a full faith
      and credit obligation by the United States of America, which, in either
      case (i) or (ii), is not callable or redeemable at the option of the
      issuer thereof, and (y) any depositary receipt issued by a bank (as
      defined in Section 3(a)(2) of the Securities Act of 1933, as amended) as
      custodian with respect to any U.S. Government Obligation specified in
      Clause (x) and held by such custodian for the account of the holder of
      such depositary receipt, or with respect to any specific payment of
      principal of or interest on any such U.S. Government Obligation, provided
      that (except as required by law) such custodian is not authorized to make
      any deduction from the amount payable to the holder of such depositary
      receipt from any amount received by the custodian in respect of the U.S.
      Government Obligation or the specific payment of principal or interest
      evidenced by such depositary receipt.

            (2) In the case of an election under Section 14.02, the Company
      shall have delivered to the Trustee an Opinion of Counsel stating that (A)
      the Company has received from, or there has been published by, the
      Internal Revenue Service a ruling or (B) since the date first set forth
      hereinabove, there has been a change in the applicable Federal income tax
      law, in either case (A) or (B) to the effect that, and based thereon such
      opinion shall confirm that, the Holders of 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.

            (3) In the case of an election under Section 14.03, the Company
      shall have delivered to the Trustee an Opinion of Counsel to the effect
      that the Holders of the Outstanding Securities of such series will not
      recognize gain or loss for Federal income tax purposes as a result of 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.

            (4) 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 as a result of
      such deposit.

            (5) 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 5.01(6) and (7), at any
      time on or prior to the 90th day after the date of such deposit (it being
      understood that this condition shall not be deemed satisfied until after
      such 90th day).

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

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

            (8) 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.

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

<PAGE>

Section 14.05 Deposited Money and U.S. Government Obligations to be Held in
Trust; Other Miscellaneous Provisions.

            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 and Section 14.06, the Trustee and any such other
trustee are referred to collectively as the "Trustee") pursuant to Section 14.04
in respect of the Securities of any Defeasible Series shall 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.

            The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 14.04 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.

            Anything in this Article XIV to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 14.04 with respect to Securities of any Defeasible Series that, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof 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 14.06 Reinstatement.

            If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article XIV 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
shall be revived and reinstated as though no deposit had occurred pursuant to
this Article XIV 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 14.05 with respect to Securities of such series in
accordance with this Article XIV; 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 shall 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 XV

                            CONVERSION OF SECURITIES

Section 15.01 Applicability; Conversion Privilege and Conversion Price.

            Securities of any series which are convertible into Common Stock of
the Company shall be convertible in accordance with their terms and (except as
otherwise specified as contemplated by Section 3.01 for Securities of any
series) in accordance with this Article.

            Subject to and upon compliance with the provisions of this Article,
at the option of the Holder thereof, any Security or any portion of the
outstanding principal amount thereof which is $1,000 or an integral multiple of
$1,000 may be converted at the principal amount thereof, or of such portion
thereof, into fully paid and nonassessable shares (calculated as to each
conversion to the nearest 1/100 of a share) of Common Stock of the Company at
the conversion price, determined as hereinafter provided, in effect at the time
of conversion. Such conversion right shall expire at the close of business on
the date specified for Securities of such series. In case a Security or portion
thereof is called for redemption at the election of the Company, such conversion
right in respect of the Security or portion so called shall expire at the close
of business on the 10th calendar day before the Redemption Date, unless the
Company defaults in making the payment due upon redemption.

<PAGE>

            The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "conversion price") shall be the price specified
in relation to Securities of such series pursuant to Section 3.01, as it shall
be adjusted in certain instances as provided in this Article.

Section 15.02 Exercise of Conversion Privilege.

            In order to exercise the conversion privilege, the Holder of any
Security to be converted shall surrender such Security, duly endorsed or
assigned to the Company or in blank, at any office or agency of the Company
maintained for that purpose, accompanied by written notice to the Company (which
shall be substantially in the form set forth in Section 2.03) at such office or
agency that the Holder elects to convert such Security or, if less than the
entire principal amount thereof is to be converted, the portion thereof to be
converted. Securities surrendered for conversion during the period from the
close of business on any Regular Record Date next preceding any Interest Payment
Date to the opening of business on such Interest Payment Date shall (except in
the case of Securities or portions thereof which have been called for redemption
on a Redemption Date within such period) be accompanied by payment in funds
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the principal amount of Securities being surrendered
for conversion. Subject to the provisions of Section 3.07 relating to the
payment of Defaulted Interest by the Company, the interest payment with respect
to a Security called for redemption on a Redemption Date during the period from
the close of business on any Regular Record Date next preceding any Interest
Payment Date to the opening of business on such Interest Payment Date shall be
payable on such Interest Payment Date to the Holder of such Security at the
close of business on such Regular Record Date notwithstanding the conversion of
such Security after such Regular Record Date and prior to such Interest Payment
Date, and the Holder converting such Security need not include a payment of such
interest payment amount upon surrender of such Security for conversion. Except
as provided in the preceding sentence and subject to the final paragraph of
Section 3.07, no payment or adjustment shall be made upon any conversion on
account of any interest accrued on the Securities surrendered for conversion or
on account of any dividends on the Common Stock issued upon conversion.

            Securities shall be deemed to have been converted immediately prior
to the close of business on the day of surrender of such Securities for
conversion in accordance with the foregoing provisions, and at such time the
rights of the Holders of such Securities as Holders shall cease, and the Person
or Persons entitled to receive the Common Stock issuable upon conversion shall
be treated for all purposes as the record holder or holders of such Common Stock
at such time. As promptly as practicable on or after the conversion date, the
Company shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 15.03.

            In the case of any Security which is converted in part only, upon
such conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in aggregate principal amount equal to
the unconverted portion of the principal amount of such Security.

Section 15.03 Fractions of Shares.

            No fractional shares of Common Stock shall be issued upon conversion
of Securities. If more than one Security shall be surrendered for conversion at
one time by the same Holder, the number of full shares which shall be issuable
upon conversion thereof shall be computed on the basis of the aggregate
principal amount of the Securities (or specified portions thereof) so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be issuable upon conversion of any Security or Securities (or
specified portions thereof), the Company shall pay a cash adjustment in respect
of such fraction in an amount equal to the same fraction of the daily closing
price per share of Common Stock (consistent with Section 15.04(6) below) at the
close of business on the day of conversion.

Section 15.04 Adjustment of Conversion Price.

            (1) In case the Company shall pay or make a dividend or other
      distribution on any class of capital stock of the Company in Common Stock,
      the conversion price in effect at the opening of business on the day

<PAGE>

      following the date fixed for determination of stockholders entitled to
      receive such dividend or other distribution shall be reduced by
      multiplying such conversion price by a fraction of which the numerator
      shall be the number of shares of Common Stock outstanding at the close of
      business on the date fixed for such determination and the denominator
      shall be the sum of such number of shares and the total number of shares
      constituting such dividend or other distribution, such reduction to become
      effective immediately after the opening of business on the day following
      the date fixed for such determination. For the purposes of this paragraph
      (1), the number of shares of Common Stock at any time outstanding shall
      not include shares held in the treasury of the Company but shall include
      shares issuable in respect of scrip certificates issued in lieu of
      fractions of shares of Common Stock. The Company will not pay any dividend
      or make any distribution on shares of Common Stock held in the treasury of
      the Company.

            (2) In case the Company shall issue rights or warrants to all
      holders of its Common Stock entitling them to subscribe for or purchase
      shares of Common Stock at a price per share less than the current market
      price per share (determined as provided in paragraph (6) of this Section)
      of the Common Stock on the date fixed for the determination of
      stockholders entitled to receive such rights or warrants (other than
      pursuant to a dividend reinvestment plan), the conversion price in effect
      at the opening of business on the day following the date fixed for such
      determination shall be reduced by multiplying such conversion price by a
      fraction of which the numerator shall be the number of shares of Common
      Stock outstanding at the close of business on the date fixed for such
      determination plus the number of shares of Common Stock which the
      aggregate of the offering price of the total number of shares of Common
      Stock so offered for subscription or purchase would purchase at such
      current market price and the denominator shall be the number of shares of
      Common Stock outstanding at the close of business on the date fixed for
      such determination plus the number of shares of Common Stock so offered
      for subscription or purchase, such reduction to become effective
      immediately after the opening of business on the day following the date
      fixed for such determination. For the purposes of this paragraph (2), the
      number of shares of Common Stock at any time outstanding shall not include
      shares held in the treasury of the Company but shall include shares
      issuable in respect of scrip certificates issued in lieu of fractions of
      shares of Common Stock. The Company will not issue any rights or warrants
      in respect of shares of Common Stock held in the treasury of the Company.

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

            (4) In case the Company shall, by dividend or otherwise, distribute
      to all holders of its Common Stock evidences of its indebtedness or assets
      (including securities, but excluding any rights or warrants referred to in
      paragraph (2) of this Section, any dividend or distribution paid in cash
      out of the earned surplus of the Company and any dividend or distribution
      referred to in paragraph (1) of this Section), the conversion price shall
      be adjusted so that the same shall equal the price determined by
      multiplying the conversion price in effect immediately prior to the close
      of business on the date fixed for the determination of stockholders
      entitled to receive such distribution by a fraction of which the numerator
      shall be the current market price per share (determined as provided in
      paragraph (6) of this Section) of the Common Stock on the date fixed for
      such determination less the then fair market value (as determined by the
      Board of Directors, whose determination shall be conclusive and described
      in a Board Resolution filed with the Trustee) of the portion of the assets
      or evidences of indebtedness so distributed applicable to one share of
      Common Stock and the denominator shall all be such current market price
      per share of the Common Stock, such adjustment to become effective
      immediately prior to the opening of business on the day following the date
      fixed for the determination of stockholders entitled to receive such
      distribution.

            (5) The reclassification of Common Stock into securities other than
      Common Stock (other than any reclassification upon a consolidation or
      merger to which Section 15.11 applies) shall be deemed to

<PAGE>

      involve (a) a distribution of such securities other than Common Stock to
      all holders of Common Stock (and the effective date of such
      reclassification shall be deemed to be "the date fixed for the
      determination of stockholders entitled to receive such distribution" and
      the "date fixed for such determination" within the meaning of paragraph
      (4) of this Section), and (b) a subdivision or combination, as the case
      may be, of the number of shares of Common Stock outstanding immediately
      prior to such reclassification into the number of shares of Common Stock
      outstanding immediately thereafter (and the effective date of such
      reclassification shall be deemed to be "the day upon which such
      subdivision becomes effective" or "the day upon which such combination
      becomes effective", as the case may be, such "the day upon which such
      subdivision or combination becomes effective" within the meaning of
      paragraph (3) of this Section).

            (6) For the purpose of any computation under paragraphs (2) and (4)
      of this Section, the current market price per share of Common Stock on any
      day shall be deemed to be the average of the daily closing prices for the
      five consecutive trading days (ie., Business Days on which the Common
      Stock is traded) selected by the Board of Directors commencing not more
      than 20 trading days before, and ending not later than, the earlier of the
      day in question and the day before the "ex" date with respect to the
      issuance or distribution requiring such computation. For this purpose, the
      term "'ex' date", when used with respect to any issuance or distribution,
      shall mean the first date on which the Common Stock trades regular way on
      the applicable exchange or in the applicable market without the right to
      receive such issuance or distribution. The closing price for each day
      shall be the reported last sale price regular way or, in case no such
      reported sale takes place on such day, the average of the reported closing
      bid and asked prices regular way, in either case on the New York Stock
      Exchange or, if the Common Stock is not listed or admitted to trading on
      such Exchange, on the principal national securities exchange on which the
      Common Stock is listed or admitted to trading or, if not listed or
      admitted to trading on any national securities exchange, on the Nasdaq
      Stock Market or, if the Common Stock is not listed or admitted to trading
      on any national securities exchange or quoted on the Nasdaq Stock Market,
      the average of the closing bid and asked prices in the over-the-counter
      market as furnished by any New York Stock Exchange member firm selected
      from time to time by the Board of Directors for that purpose.

            (7) The Company may make such reductions in the conversion price, in
      addition to those required by paragraphs (1), (2), (3) and (4) of this
      Section, as it considers to be advisable in order to avoid or diminish any
      income tax to any holders of shares of Common Stock resulting from any
      dividend or distribution of stock or issuance of rights or warrants to
      purchase or subscribe for stock or from any event treated as such for
      income tax purposes or for any other reasons. The Company shall have the
      power to resolve any ambiguity or correct any error in this paragraph (7)
      and its actions in so doing shall be final and conclusive.

            (8) No adjustment in the conversion price shall be required unless
      such adjustment would require an increase or decrease of at least one
      percent in such conversion price; provided, however, that any adjustments
      which by reason of this paragraph (8) is not required to be made shall be
      carried forward and taken into account in any subsequent adjustment. All
      calculations under this Article shall be made to the nearest cent or to
      the nearest 1/100 of a share, as the case may be.

 Section 15.05 Notice of Adjustments of Conversion Price.

            Whenever the conversion price is adjusted as herein provided:

            (a) the Company shall compute the adjusted conversion price in
accordance with Section 15.04 and shall prepare a certificate signed by the
Treasurer of the Company setting forth the adjusted conversion price and showing
in reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be filed at each office or agency maintained for the
purpose of conversion of Securities; and

            (b) a notice stating that the conversion price has been adjusted and
setting forth the adjusted conversion price shall forthwith be required, and as
soon as practicable after it is required, such notice shall be mailed by the
Company to all Holders at their last addresses as they shall appear in the
Security Register.

Section 15.06 Notice of Certain Corporate Action.

            In case:

            (a) the Company shall declare a dividend (or any other distribution)
on its Common Stock payable otherwise than in cash out of its earned surplus; or

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

            (c) of any reclassification of the Common Stock of the Company
(other than a subdivision or combination of its outstanding shares of Common
Stock), or of any consolidation, merger or share exchange to which the Company
is a party and for which approval of any stockholders of the Company is
required, or of the sale or transfer of all or substantially all of the assets
of the Company; or

            (d) of the voluntary or involuntary dissolution, liquidation or
winding up of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities, and shall cause to be mailed to all
Holders at their last addresses as they shall appear in the Security Register,
at least 20 days (or 10 days in any case specified in clause (a) or (b) above)
prior to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to
such dividend, distribution, rights or warrants are to be determined, or (y) the
date on which such reclassification, consolidation, merger, share exchange,
sale, transfer, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, share exchange, sale, transfer, dissolution, liquidation
or winding up. Neither the failure to give such notice nor any defect therein
shall affect the legality or validity of the proceedings described in clauses
(a) through (d) of this Section 15.06. If at the time the Trustee shall not be
the conversion agent, a copy of such notice shall also forthwith be filed by the
Company with the Trustee.

            Not less than seven days prior to any date fixed for the
determination of stockholders entitled to receive such distribution, the Company
shall cause to be filed at each office or agency maintained for the purpose of
conversion of Securities, and shall cause to be mailed to all Holders at their
last addresses as they shall appear in the Security Register, a notice stating
the date on which the such determination is to be made, and briefly describing
the import thereof. If at the time the Trustee shall not be the conversion
agent, a copy of such notice shall also forthwith be filed by the Company with
the Trustee.

Section 15.07 Company to Reserve Common Stock.

            The Company shall at all times reserve and keep available out of its
authorized but unissued Common Stock, for the purpose of effecting the
conversion of Securities, the full number of shares of Common Stock then
issuable upon the conversion of all Outstanding Securities.

Section 15.08 Taxes on Conversions.

            The Company will pay any and all taxes that may be payable in
respect of the issue or delivery of shares of Common Stock on conversion of
Securities pursuant hereto. The Company shall not, however, be required to pay
any tax which may be payable in respect of any transfer involved in the issue
and delivery of shares of Common Stock in a name other than that of the Holder
of the Security or Securities to be converted, and no such issue or delivery
shall be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.

<PAGE>

Section 15.09 Covenant as to Common Stock.

            The Company covenants that all shares of Common Stock which may be
issued upon conversion of Securities will upon issue be fully paid and
nonassessable and, except as provided in Section 15.08, the Company will pay all
taxes, liens and charges with respect to the issue thereof.

Section 15.10 Cancellation of Converted Securities.

            All Securities delivered for conversion shall be delivered to the
Trustee to be cancelled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 3.09.

Section 15.11 Provisions in Case of Consolidation, Merger or Sale of Assets.

            In case of any consolidation of the Company with, or merger of the
Company into, any other Person, any merger of another Person into the Company
(other than a merger which does not result in any reclassification, conversion,
exchange or cancellation of outstanding shares of Common Stock of the Company)
or any sale or transfer of all or substantially all of the assets of the
Company, the Person formed by such consolidation or resulting from such merger
or which acquires such assets, as the case may be, shall execute and deliver to
the Trustee a supplemental indenture providing that the Holder of each
convertible Security then outstanding shall have the right thereafter, during
the period such Security shall be convertible as specified in Section 15.01, to
convert such Security only into the kind and amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer by a
holder of the number of shares of Common Stock of the Company into which such
Security might have been converted immediately prior to such consolidation,
merger, sale or transfer, assuming such holder of Common Stock of the Company
failed to exercise his rights of election, if any, as to the kind or amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or transfer (provided that if the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer is
not the same for each share of Common Stock of the Company in respect of which
such rights of election shall not have been exercised ("non-electing share"),
then for the purpose of this Section the kind and amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer by
each non-electing share shall be deemed to be the kind and amount so receivable
per share by a plurality of the non-electing shares). Such supplemental
indenture shall provide for adjustments which, for events subsequent to the
effective date of such supplemental indenture, shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Article. The above
provisions of this Section shall similarly apply to successive consolidations,
mergers, sales or transfers.

Section 15.12 Responsibility of Trustee.

            Neither the Trustee nor any conversion agent shall at any time be
under any duty or responsibility to any Holder of Securities to determine
whether any fact exists which may require any adjustment of the conversion
price, or with respect to the nature or extent of any such adjustment when made,
or with respect to the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same. Neither the Trustee nor
any conversion agent shall be accountable with respect to the registration,
validity or value (or the kind or amount) of any shares of Common Stock, or of
any securities or property, which may at any time be issued or delivered upon
the conversion of any Security; and neither the Trustee nor any conversion agent
makes any representation with respect thereto. Neither the Trustee nor any
conversion agent shall be responsible for any failure of the Company to issue or
transfer or deliver any Common Stock or stock certificates or other securities
or property or to make any cash payment upon the surrender of any Security for
the purpose of conversion or to comply with any of the covenants of the Company
contained in this Article XV.

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

      FOURTH AMENDMENT
TO THE IRON MOUNTAIN INCORPORATED

      2002 STOCK
INCENTIVE PLAN

       

       

      1.  The Iron
Mountain Incorporated 2002 Stock Incentive Plan, as previously amended (the
“2002 Plan”), shall be further amended by adding the following new Section
11A:

       

      Section
11A.  Acceleration of Vesting on a
Vesting Change in Control.

       

      (a)  Notwithstanding
the provisions of Section 11 and except as otherwise explicitly provided in a
Stock Option Agreement, Restricted Stock Agreement, SAR Agreement or similar
agreement, if as a result of and within fourteen (14) days before or twelve (12)
months after a Vesting Change in Control (1) Optionee’s employment is terminated
by Iron Mountain or any successor or assign (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business and/or assets of Iron Mountain or (2) Optionee terminates his or her
employment due to a Good Reason, then on the date of such termination, all
outstanding Options and Other Rights held by Optionee that are unvested as of
the Vesting Change in Control shall immediately vest; provided, however, that
Optionee shall execute and deliver a reaffirmation of any Employee
Confidentiality and Non-Competition Agreement with Iron Mountain.

       

      (b)  For
purposes of this Section 11A, the following definitions shall
apply:

       

      (1)  “Good
Reason” shall mean that any of the following occurs without Optionee’s prior
written consent:

       

      
        	
                 
      

              	
                (i)

              	
                a
      diminution by Iron Mountain in the total annual compensation that Optionee
      is entitled to receive or a material diminution in the benefits Optionee
      is eligible to receive; or

      fifty (50) miles from where Optionee’s office is located immediately prior
      to the Vesting Change in Control except for required travel on Iron
      Mountain’s business to an extent substantially consistent with the
      business travel obligations that Optionee undertook on behalf of Iron
      Mountain prior to the Vesting Change in
Control.

      effective date:  (A) of a merger or consolidation of the Company
      with any other third party, other than a merger or consolidation that

      outstanding or by being converted into voting securities of the surviving
      entity or the entity that controls such surviving entity) at least fifty
      percent (50%) of the total voting power represented by the voting
      securities of the Company, such surviving entity or the entity that
      controls such surviving entity outstanding immediately after such merger
      or consolidation; or (B) of the sale or disposition of the Company of all
      or substantially all of the Company’s assets;

                individuals
      who on December 4, 2008 constituted the Company’s Board of Directors

      or whose nomination for election by the stockholders, was approved by a
      vote of two-thirds of the directors then in office who were either
      directors at the beginning of such period or whose election or nomination
      was previously so approved) cease to constitute a majority of the Board of
      Directors of the Company then in
