waiver or other action provided 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 an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such

                                       8
<PAGE>

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

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit 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.

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

         (d) Any request, demand, authorization, direction, notice, consent,

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.

         (e) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Securities of any series entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to
vote on any action, authorized or permitted to be given or taken by Holders of
Securities of such series. If not set by the Company prior to the first
solicitation of a Holder of Securities of such series made by any Person in
respect of any such action, or in the case of any such vote, prior to such vote,
the record date for any such action or vote shall be the 30th day (or, if later,
the date of the most recent list of Holders required to be provided pursuant to
Section 7.01) prior to such first solicitation or vote, as the case may be. With
regard to any record date for action to be taken by the Holders of one or more
series of Securities, only the Holders of Securities of such series on such date
(or their duly designated proxies) shall be entitled to give or take, or vote
on, the relevant action.

         (f) Without limiting the foregoing, a Holder entitled hereunder to
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 part of such principal amount. Any notice given or
action taken by a Holder or its agents with regard to different parts of such
principal amount pursuant to this paragraph shall have the same effect as if
given or taken by separate Holders of each such different part.

         (g) Without limiting the generality of the foregoing, unless otherwise
specified pursuant to Section 3.01 or pursuant to one or more indentures
supplemental hereto, a Holder,

                                       9
<PAGE>

including a Depositary that is the Holder of a Global Security, may make, give
or take, by a proxy or proxies duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other action provided in
this Indenture to be made, given or taken by Holders, and a Depositary that is
the Holder of a Global Security may provide its proxy or proxies to the
beneficial owners of interests in any such Global Security through such
Depositary's standing instructions and customary practices.

          (h) The Trustee shall fix a record date for the purpose of determining
the Persons who are beneficial owners of interests in any Global Security held
by a Depositary entitled under the procedures of such Depositary to make, give
or take, by a proxy or proxies duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other action provided in
this Indenture to be made, given or taken by Holders. If such a record date is
fixed, the Holders on such record date or their duly appointed proxy or proxies,
and only such Persons, shall be entitled to make, give or take such request,
demand, authorization, direction, notice, consent, waiver or other action,
whether or not such Holders remain Holders after such record date. No such
request, demand, authorization, direction, notice, consent, waiver or other
action shall be valid or effective if made, given or taken more than 90 days
after such record date.

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 to or with the Trustee at its Corporate Trust Office,
          Attention: ___________________________, 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 Indenture,
          Attention: Secretary, 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, and not earlier than the earliest date, 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. Any notice to a Holder which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given, whether
or not such Holder receives such notice. 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

                                       10
<PAGE>

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 or irregularities in regular
mail service or by reason of any other cause, it shall be impracticable to give
notice of any event to Holders by mail when such notice is required to be given
pursuant to any provision of this Indenture, 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 the duties
imposed by any of Sections 3.10 through 3.17, inclusive, of the Trust Indenture
Act through the operation of Section 3.18(c) thereof, such imposed duties shall
control. If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or shall be
deemed to be so excluded, as the case may be.

shall give to any Person, other than the parties hereto and their successors
hereunder, any Paying Agent, the Holders and the holders of Senior Debt, any
benefit or any legal or equitable right, remedy or claim under this Indenture;
provided that this Section 1.11 shall not limit the rights of any Holder of a
Global Security to give any notice or take any action, or appoint any agents,
with regard to any part or different parts of the principal amount of such
Global Security pursuant to Section 1.04.

         Section 1.12 Governing Law.

principal (and premium, if any) need not be made on such date, but may be made
on the next succeeding Business Day with the same force and effect as if made on
the Interest Payment Date, Redemption Date, Repayment Date, sinking fund payment
date or at the Stated Maturity, provided that no interest shall accrue for the
period from and after such Interest Payment Date, Redemption Date, Repayment
Date, sinking fund payment date or Stated Maturity, as the case may be.

                                  ARTICLE II.

one or more indentures supplemental hereto, in each case with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture, and may have such letters, numbers or other marks
of identification and such legends or endorsements placed thereon as may be
required to comply with any law or with any rules made pursuant thereto or the
rules of any securities exchange or as may, consistently herewith, be determined

may be produced in any other manner permitted by the rules of any securities
exchange upon which the Securities may be listed and (with respect to Global
Securities of any Series) the rules of the Depositary, all as determined by the
officers executing such Securities, as evidenced by their execution of such
Securities.

       Section 2.03 Securities in Global Form.

       If any Security of a series is issuable in global form, such Security
may provide that it shall represent the aggregate amount of Outstanding
Securities from time to time endorsed thereon and also may provide that the
aggregate amount of Outstanding Securities represented thereby may from time to
time be reduced to reflect exchanges. Any endorsement of a Security in global
form to reflect the amount, or any increase or decrease in the amount, of
Outstanding Securities represented thereby shall be made by the Trustee and in
such manner as shall be specified in such Security. Any instructions by the
Company with respect to a Security in global form, after its initial issuance,
shall be in writing but need not comply with Section 1.02.

                                  ARTICLE III.

       The Securities may be issued in one or more series. All Securities of
each series issued under this Indenture shall in all respects be equally and
ratably entitled to the benefits hereof with respect to such series without

authentication and delivery or Maturity of the Securities of such series. There

     series pursuant to Section 3.04, 3.05, 3.06, 9.06, 11.06, 13.05 or 14.03);

                                       13

          (4) the date or dates on which the principal and premium, if any, of
     the Securities of the series is payable;

          (5) the rate or rates (which may be fixed or variable), or the method
     of determination thereof, at which the Securities of the series shall bear
     interest, if any, the date or dates from which such interest shall accrue,
     the Interest Payment Dates on which such interest shall be payable and the
     Regular Record Date for the interest payable on any Interest Payment Date
     or, if the principal amount payable at the Stated Maturity of any of the
     Securities will not be determinable as of any one or more dates prior to
     the Stated Maturity, the amount which will be deemed to be such principal
     amount as of any such date for any purpose, including the principal amount
     thereof which will be due and payable upon any Maturity other than the
     Stated Maturity or which will be deemed to be Outstanding as of any such
     date (or, in any such case, the manner in which such deemed principal
     amount is to be determined);

          (6) if other than the Corporate Trust Office, the place or places
     where the principal of (and premium, if any) and interest on Securities of
     the series shall be payable;

          (7) the period or periods within which, the price or prices at which
     and the terms and conditions upon which Securities of the series may be
     redeemed, in whole or in part, at the option of the Company;

          (8) the obligation, if any, of the Company to redeem or purchase
     Securities of the series pursuant to any mandatory sinking fund or
     analogous provisions or at the option of a Holder thereof and the period or
     periods within which, the price or prices at which and the terms and
     conditions upon which Securities of the series shall be redeemed or
     purchased, in whole or in part, pursuant to such obligation;

          (9) if other than denominations of $1,000 and any integral multiple
     thereof, the denominations in which Securities of the series shall be
     issuable;

          (10) if other than the principal amount thereof, the portion of the
     principal amount of Securities of the series which shall be payable upon

     part in the form of a Global Security or Securities, the terms and
     conditions upon which such Global Security may be exchanged in whole or in
     part for other individual securities and the Depositary for such Global
     Security or Securities;

          (12) any addition to or change in the Events of Default which apply to

           (17) the listing of the Securities on any securities exchange or the
     inclusion in any other market or quotation or trading system;

           (18) any Trustee, Authenticating Agent, Paying Agent, issuing or
     transfer agent or Securities Registrar or any other Person appointed to act
     in connection with such Securities for or on behalf of the Holders thereof
     or the Company; and

           (19) any other terms of the series (which terms shall not be
     inconsistent with the provisions of this Indenture).

         The Securities shall be subordinate and junior in right of payment to
Senior Debt of the Company as provided in Article XVI.

         All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to such Board Resolution and set forth in such Officers' Certificate, to the
extent applicable, or in any such indenture supplemental hereto. All Securities
of any one series need not be issued at the same time and, unless otherwise
provided, a series may be reopened, without the consent of the Holders, for
issuance of additional Securities of such series.

         If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Board Resolution or
the Officers' Certificate setting forth the terms of the series.

         Section 3.02 Denominations.

         The Securities of each series shall be issuable in registered form with
or without coupons in such denominations as shall be specified as contemplated
by Section 3.01. In the absence of any such provisions 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 or one of
its Vice Presidents. 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.

                                       15
<PAGE>

         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, and the Trustee shall authenticate
and deliver such Securities upon Company Order. If all the Securities of any one
series are not to be originally issued at one time and if a Board Resolution
relating to such Securities shall so permit, such Company Order may set forth
procedures (acceptable to the Trustee) for the issuance and authentication of
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:

               (a) 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;

               (b) 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

               (c) 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 Board Resolution or Officers'
Certificate otherwise required pursuant to Section 3.01 or the Company Order and
Opinion of Counsel otherwise required pursuant to this Section 3.03 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 and such documents reasonably
contemplate the issuance of all Securities of such series.

         Unless otherwise provided in the form of Security for any series, 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 of an authorized

                                       16
<PAGE>

officer, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.

         If the Company shall establish pursuant to Section 3.01 that the
Securities of a series are to be issued in the form of one or more Global
Securities, then the Company shall execute and the Trustee shall, in accordance
with this Section and the Company Order with respect to such series,
authenticate and deliver one or more Global Securities that (i) shall represent
and shall be denominated in an amount equal to the aggregate principal amount of
all of the Securities of such series having the same terms issued and not yet
canceled, (ii) shall be registered in the name of the Depositary for such Global
Security or Securities or the nominee of such Depositary, (iii) shall be
delivered by the Trustee to such Depositary or pursuant to such Depositary's
instructions and (iv) shall bear a legend substantially to the following effect:
"Unless and until it is exchanged in whole or in part for Securities in
definitive registered form, this Security may not be transferred except as a
whole by the Depositary to the nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary."

         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. Every such temporary Security
shall be executed by the Company and shall be authenticated and delivered by the
Trustee upon the same conditions and in substantially the same manner, and with
the same effect, as the definitive Security in lieu of which it is issued.

         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 a like principal
amount of definitive Securities of the same series of authorized denominations.
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.

         Section 3.05 Registration, Registration of Transfer and Exchange
and Book-Entry Securities.

         The Company shall cause to be kept at one of its offices or agencies
maintained pursuant to Section 10.02 a register (the register maintained in such
office being herein sometimes

                                       17
<PAGE>

referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of exchanges and transfers of Securities. The Person responsible for the
maintenance of the Security Register is referred to herein as the "Security
Registrar." The Trustee is hereby initially appointed Security Registrar for the
purpose of registering Securities and transfers of Securities as herein
provided. The exchange of and the transfer of Securities also may be registered
at the office of the Trustee.

         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.

         At the option of the Holder, Securities of any series (except Global
Securities) may be exchanged for other Securities of the same series (except
Global Securities) of any authorized denominations and of a like aggregate
principal amount, 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 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 Security Registrar) 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 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, 11.06, 13.05 or 14.03 not involving
any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 11.02 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer or exchange of 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 of this Section 3.05, unless and
until it is exchanged in whole or in part for Securities in definitive
registered form, a Global Security representing all or a portion of the
Securities of a series may not be transferred except as a whole by the
Depositary for such series to a nominee of such Depositary or by a nominee of
such Depositary to such Depositary

                                       18
<PAGE>

or another nominee of such Depositary or by such Depositary or any such nominee
to a successor Depositary for such series or a nominee of such successor
Depositary.

         If at any time the Depositary for the Securities of a series notifies
the Company that it is unwilling or unable to continue as Depositary for the
Securities of such series or if at any time the Depositary for the Securities of
a series shall no longer be registered or in good standing under the Securities
Exchange Act of 1934, as amended, or other applicable statute or regulation, the
Company shall appoint a successor Depositary with respect to the Securities of
such series. If a successor Depositary for the Securities of such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, the Company shall execute, and the Trustee,
upon receipt of a Company Order for the authentication and delivery of
definitive Securities of such series, shall authenticate and deliver Securities
of such series in definitive form in an aggregate principal amount equal to the
principal amount of the Global Security or Securities representing such series
in exchange for such Global Security or Securities.

         The Company may at any time and in its sole discretion determine that
the Securities of any series issued in the form of one or more Global Securities
shall no longer be represented by a Global Security or Securities. In such event
the Company shall execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of definitive Securities of such series, shall
authenticate and deliver, Securities of such series in definitive registered
form without coupons, in any authorized denominations, in an aggregate principal
amount equal to the principal amount of the Global Security or Securities
representing such series, in exchange for such Global Security or Securities.

         If (1) an Event of Default shall occur and be continuing and (2)
beneficial owners of interests representing a majority in aggregate principal
amount of the Securities of a series represented by a Global Security or
Securities shall advise the Trustee through the Depositary for such Global
Security or Securities in writing that the maintenance of a Depositary for such
series is no longer in such beneficial owners' best interests, the Company shall
execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of definitive Securities of such series, shall authenticate and
deliver, Securities of such series in definitive registered form without
coupons, in any authorized denominations, in an aggregate principal amount equal
to the principal amount of the such Global Security or Securities, in exchange
for such Global Security or Securities.

         If specified by the Company pursuant to Section 3.01 with respect to a
series of Securities, the Depositary for such series of Securities may surrender
a Global Security for such series of Securities in exchange in whole or in part
for Securities of such series in definitive registered form on such terms as are
acceptable to the Company and such Depositary. Thereupon, the Company shall
execute, and the Trustee shall authenticate and deliver, without service charge,

               (i) to the Person specified by such Depositary a new Security or
          Securities of the same series, of any authorized denomination as
          requested by such Person, in an aggregate principal amount equal to
          and in exchange for such Person's beneficial interest in the Global
          Security; and

                                       19
<PAGE>

               (ii) to such Depositary a new Global Security in a denomination
          equal to the difference, if any, between the principal amount of the
          surrendered Global Security and the aggregate principal amount of
          Securities authenticated and delivered pursuant to Clause (i) above.

         Upon the exchange of a Global Security for Securities in definitive
registered form, in authorized denominations, such Global Security shall be
canceled by the Trustee. Securities in definitive registered form issued in
exchange for a Global Security pursuant to this Section 3.05 shall be registered
in such names and in such authorized denominations as the Depositary for such
Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall not be
liable for any delay in delivery of such instructions and may conclusively rely
on, and shall be protected in relying on, such instructions. The Trustee shall,
at Company expense, deliver such Securities to or as directed by the Persons in
whose names such Securities are so registered.

         Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee, together with
such other security or indemnity as may be reasonably required by the Trustee to
save it harmless, 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 upon its request 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, subject to satisfaction of
the foregoing conditions. 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
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, 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.

                                       20
<PAGE>

         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. The Company and the Trustee understand that interest on any
Global Security will be disbursed or credited by the Depositary to the Persons
having ownership thereof pursuant to a book entry or other system maintained by
the Depositary.

         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 Clause (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 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

                                       21

          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.

         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 premium,
if any) and (subject to Section 3.07) 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.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

         Section 3.09 Cancellation.

         Unless otherwise specified pursuant to Section 3.01(6) for Securities
of any series all Securities surrendered for payment, redemption, registration
of transfer or exchange or for credit against any mandatory sinking fund payment
shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee and shall be promptly canceled 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 all Securities so delivered shall be promptly canceled by the
Trustee, except that if a Global Security is so surrendered, the Company shall
execute and the Trustee shall authenticate and deliver to the Depositary for
such Global Security, without service charge, a new Global Security or
Securities in a denomination equal to and in exchange for the portion of the
Global Security so surrendered not to be paid, redeemed, repaid or registered
for transfer or exchange or for credit. No Securities shall be authenticated in
lieu of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture. All canceled Securities held by
the Trustee shall be disposed of in accordance with its customary procedures and
a certificate of disposition shall be delivered to the Company, unless, by a
Company Order, the Company shall direct the canceled Securities be returned to
it.

         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 4.01 Satisfaction and Discharge of Indenture.

         Upon Company Request, this Indenture shall cease to be of further
effect with respect to the Securities of a particular series, and the Trustee,
at the expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture as to such Securities, when:

               (1)  either:

                    (A) all Securities of such series 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

               been delivered to the Trustee for cancellation; or

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

                         (i) have become due and payable, or

                         (ii) will become due and payable at their Stated

                    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
               irrevocably deposited or caused to be irrevocably deposited
               with the Trustee as trust funds in trust for such purpose sums
               sufficient to pay and discharge the entire indebtedness on
               such Securities not theretofore delivered to the Trustee for
               cancellation, for principal (and premium, if any) 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; and

               (2) the Company has paid or caused to be paid all other sums
          payable hereunder by the Company with respect to such Securities; 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

                                       23

          to the satisfaction and discharge of this Indenture with respect to
          the Securities of such series have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture with
respect to the Securities of a particular series, the obligations of the Company
to the Trustee under Section 6.07, the obligations, if any, of the Trustee to
any Authenticating Agent under Section 6.14 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 and the last
paragraph of Section 10.03, in each case with respect to such Securities, shall
survive.

         Notwithstanding the cessation, termination and discharge of all
obligations, covenants and agreements of the Company under this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 6.07 and the obligations of the Trustee under Section 4.02
and the last paragraph of Section 10.03 shall survive with respect to such
series of Securities.

         Section 4.02 Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 10.03, all
money deposited with the Trustee pursuant to Section 4.01 shall be held in trust

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 premium, if
any) and interest for whose payment such money has been deposited with the
Trustee.

               (4) default in the performance of any covenant or warranty of the

          in whose performance or whose breach is elsewhere in this Section 5.01
          specifically dealt with or which has expressly been included in this
          Indenture solely for the benefit of a series of Securities other than
          that series), and continuance of such default for a period of 60 days

          aggregate principal amount of the Outstanding Securities of that

          giving effect to any applicable grace period or (ii) in the

          due and payable prior to the date on which it would otherwise become
          due and payable, and such acceleration shall not have been rescinded
          or annulled, or such Debt shall not have been discharged, within a
          period of 90 days after there has been given, by registered or

          decrees or orders by a court having jurisdiction in the premises from
          which no appeal may be or is taken for the payment of money, either
          individually or in the aggregate, in excess of $75,000,000, and the
          continuance of such judgment, decree or order unsatisfied and in
          effect for any period of 90 consecutive days after the amount thereof
          is due without a stay of execution and there has been given, by
          registered or certified mail, to the Company by the Trustee or to the
          Company and the Trustee by the Holders of at least a majority in
          aggregate principal amount of the Outstanding Securities of that
          series, a written notice specifying such entry and continuance of such

          Default" hereunder; or

               (7) the entry of a decree or order for relief in respect of the
          Company by a court having jurisdiction in the premises in an
          involuntary case under the federal bankruptcy laws, as now or
          hereafter constituted, or any other applicable federal or state
          bankruptcy, insolvency or other similar law, or a decree or order
          adjudging the Company a bankrupt or insolvent, or approving as
          properly filed a petition seeking reorganization, arrangement,

          any such decree or order unstayed and in effect for a period of 90
          consecutive days; or

                                       25
<PAGE>

               (8) the commencement by the Company of a voluntary case under the
          federal bankruptcy laws, as now or hereafter constituted, or any other
          applicable federal or state bankruptcy, insolvency or other similar
          law, or the consent by it to the entry of an order for relief in an
          involuntary case under any such law or to the appointment of a
          receiver, liquidator, assignee, custodian, trustee, sequestrator (or
          other similar official) of the Company or of any substantial part of
          its property, or the making by it of an assignment for the benefit of
          its creditors, or the admission by it in writing of its inability to
          pay its debts generally as they become due, or the taking of corporate
          action by the Company in furtherance of any such action.

         Upon receipt by the Trustee of any proposed Notice of Default from any
Holder with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such proposed Notice of Default, which record date shall be at the close of
business on the day the Trustee receives such proposed Notice of Default. The
Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such proposed Notice of Default, whether
or not such Holders remain Holders after such record date; provided, that unless
Holders of at least a majority in principal amount of the Outstanding Securities
of such series, or their proxies, shall have joined in such proposed Notice of
Default prior to the day which is 90 days after such record date, such proposed
Notice of Default shall automatically and without further action by any Holder
be canceled and of no further effect. Nothing in this paragraph shall prevent a
Holder, or a proxy of a Holder, from giving (i) after expiration of such 90-day
period, a new proposed Notice of Default identical to a proposed Notice of
Default which has been canceled pursuant to the proviso to the preceding
sentence, or (ii) during any such 90-day period, an additional proposed Notice
of Default with respect to any new or different fact or circumstance permitting
the giving of a proposed Notice of Default with respect to Securities of such
series, in either of which events a new record date shall be established
pursuant to the provisions of this Section 5.01. Any such proposed Notice of
Default shall be considered a Notice of Default hereunder at such time, if any,
that Holders of at least a majority in principal amount of the Outstanding
Securities shall have joined in such proposed Notice of Default by giving timely
notice to the Trustee hereunder.

         Section 5.02 Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default with respect to Securities of any series (other
than an Event of Default specified in Section 5.01(6) or (7)) at the time
Outstanding occurs and is continuing, then in every such case, the Trustee or
the Holders of not less than a majority 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. Upon payment of said amounts,
all obligations of the Company in respect of payment of principal of the
Securities of such series shall terminate. Notwithstanding the foregoing, if an
Event of Default specified in Section 5.01(6) or (7) hereof occurs with respect
to the Company, all Outstanding Securities shall become immediately due and
payable without further action or notice.

                                       26
<PAGE>

         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.

         Upon receipt by the Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, with respect to Securities of
a series all or part of which is represented by a Global Security, a record date
shall be established for determining Holders of Outstanding Securities of such
series entitled to join in such notice, which record date shall be at the close
of business on the day the Trustee receives such notice. The Holders on such
record date, or their duly designated proxies, and only such Persons, shall be
entitled to join in such notice, whether or not such Holders remain Holders
after such record date; provided, that unless such declaration of acceleration,
or rescission and annulment, as the case may be, shall have become effective by
virtue of the requisite percentage having joined in such notice prior to the day
which is 90 days after such record date, such notice of declaration of
acceleration, or rescission and annulment, as the case may be, shall
automatically and without further action by any Holder be canceled and of no
further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of
a Holder, from giving (i) after expiration of such 90-day period, a new written
notice of declaration of acceleration, or rescission and annulment, as the case
may be, that is identical to a written notice which has been canceled pursuant
to the proviso to the preceding sentence, or (ii) during any such 90-day period,
an additional written notice of declaration of acceleration with respect to

                                       27
<PAGE>

Securities of such series, or an additional written notice of rescission and
annulment of any declaration of acceleration with respect to any other Event of
Default with respect to Securities of such series, in either of which events a
new record date shall be established pursuant to the provisions of this Section
5.02.

         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 upon any
         Security when it 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 its Maturity, or

               (3) default is made in the making or satisfaction of any
         mandatory sinking fund payment when it becomes due pursuant to the
         terms of the Securities of any series,

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 premium, if any) and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) 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 the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may, but shall
not be obligated to, institute a judicial proceeding for the collection of the
sums so due and unpaid, may prosecute such proceeding to judgment or final
decree, and may enforce the same against the Company or any other obligor upon
such Securities and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor
upon such Securities, wherever situated.

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

         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



                                       28
<PAGE>

proceeding. In particular, the Trustee shall be authorized to file and prove a
claim for the whole amount of principal, premium and interest owing and unpaid
in respect of the Securities and to file such other papers or documents as may
be necessary or advisable in order to have claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and 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.

         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.

         Any money collected by the Trustee pursuant to this Article with
respect to the Securities of any series shall be applied in the following order,
at the date or dates fixed by the Trustee and, in case of the distribution of
such money on account of principal (or premium, if any) or interest, upon
presentation of the Securities of any series and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

               FIRST: To the payment of all amounts due the Trustee under
          Section 6.07;

               SECOND: To the payment of the amounts then due and unpaid for
          principal of (and premium, if any) and interest on the Securities of
          such series in respect of which or for the benefit of which such money
          has been collected, ratably, without preference or priority of any
          kind, according to the amounts due and payable on such Securities for
          principal (and premium, if any) and interest, respectively; and

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

         Section 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;

               (2) the Holders of not less than a majority 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
          security or indemnity 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 of the Holders of Outstanding Securities of any other series,
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 premium, if any) and (subject to
Section 3.07) interest on such Security on the Stated Maturity or Maturities
expressed in such Security (or, in the case of redemption or repayment at the
option of the Holder, on the Redemption Date or the Repayment Date, as the case
may be) 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,

                                       30
<PAGE>

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.

         Section 5.12 Control by Holders.

         The Holders of at least 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, expose the Trustee to personal liability or be
         unduly prejudicial to Holders not joining therein, and

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

         Upon receipt by the Trustee of any such direction with respect to
Securities of a series all or part of which is represented by a Global Security,
a record date shall be established for determining Holders of Outstanding
Securities of such series entitled to join in such direction, which record date
shall be determined in accordance with Section 1.04(e). The Holders on such
record date, or their duly designated proxies, and only such Persons, shall be
entitled to join in such direction, whether or not such Holders remain Holders
after such record date; provided, that unless Holders of at least a majority in
principal amount of the outstanding Securities of such series, or their proxies,
shall have been joined in such direction prior to the day which is 90 days after
such record date, such direction shall automatically and without further action
by any

                                       31
<PAGE>

Holder be canceled and of no further effect. Nothing in this paragraph shall
prevent a Holder, or a proxy of a Holder, from giving (i) after expiration of
such 90-day period, a new direction identical to a direction which has been
canceled pursuant to the provisions of the preceding sentence or (ii) during any
such 90-day period, a new direction contrary to or different from such
direction, in either of which events a new record date shall be established
pursuant to the provisions of this Section 5.12.

         Section 5.13 Waiver of Defaults.

         By Act delivered to the Company and the Trustee, the Holders of not
less than a majority in principal amount of the Outstanding Securities of any
affected series may on behalf of the Holders of all the Securities of such
series waive any existing Event of Default hereunder with respect to such series
and its consequences (including an acceleration and its consequences, including
any related payment default that resulted from such acceleration), except an
Event of Default

               (1) in the payment of the principal of (or premium, if any) or
          interest on any Security of such series or in the payment of any
          mandatory sinking fund installment with respect to the Securities 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 thereby.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Persons entitled to waive any past default
hereunder. If a record date is fixed, the Holders on such record date, or their
duly designated proxies, and only such Persons, shall be entitled to waive any
default hereunder, whether or not such Holders remain Holders after such record
date; provided, that unless such majority in principal amount shall have been
obtained prior to the date which is 90 days after such record date, any such
waiver previously given shall automatically and without further action by any
Holder be canceled and of no further effect.

         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 be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Trustee, by any Holder, or
group of Holders, holding in the aggregate more than 10% in principal amount of
the Outstanding Securities of any series, or by any Holder for the enforcement
of the payment of the principal of (or premium, if any) or interest on any
Security on or after the Stated Maturity expressed in such Security (or, in the
case of redemption or

                                       32
<PAGE>

repayment at the option of the Holder, on or after the Redemption Date or
Repayment Date, as the case may be).

         Section 5.15 Waiver of 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 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

     Section 6.01 Certain Duties and Responsibilities.

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

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

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

     (b) In case an Event of Default 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 man would
exercise or use under the circumstances in the conduct of his own affairs.

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

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

                                       33
<PAGE>

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

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

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

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

     Section 6.02 Notice of Defaults.

     Within 90 days after the occurrence of any default hereunder with respect
to Securities of any series, the Trustee shall transmit by mail to all Holders
of Securities of such series, as their names and addresses appear in the
Security Register, notice of such default hereunder known to the Trustee, unless
such default shall have been cured or waived; provided, however, that, except in
the case of a default in the payment of the principal, premium or interest on
any Security of such series or in the payment of any mandatory sinking fund
installment with respect to the Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee of the board of directors and/or Responsible Officers of
the Trustee in good faith determine that the withholding of such notice is in
the interests of the Holders of the Securities of such series; and provided,
further, that in the case of any default of the character specified in Section
5.01(4) with respect to the Securities of such series no such notice to Holders
shall be given until at least 60 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, an Event of Default.

     Section 6.03 Certain Rights of Trustee.

     Subject to the provisions of Section 6.01:

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

                                       34
<PAGE>

     (b) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

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

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

     (e) the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Holders pursuant to this Indenture, unless such Holders shall have offered
to the Trustee reasonable security or indemnity against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or
direction;

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

     (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder; and

     (h) the Trustee shall not be required to take notice or be deemed to have
notice of any default hereunder (except failure by the Company to pay principal
of (or premium, if any) or interest on any series of Securities so long as the
Trustee is also acting as Paying Agent for such series of Securities) unless the
Trustee shall be specifically notified in writing of such default by the Company
or by the Holders of at least a 10% in aggregate principal amount of all
Outstanding Securities, and all such notices or other instruments required by
this Indenture to be delivered to the Trustee must, in order to be effective, be
delivered at the principal Corporate Trust Office of the Trustee, and in the
absence of such notice the Trustee may conclusively assume there is no default
except as aforesaid.

     Section 6.04 Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee or any Authenticating Agent assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities. The Trustee

                                       35
<PAGE>

or any Authenticating Agent shall not be accountable for the use or application
by the Company of Securities or the proceeds thereof. The Trustee shall not be
deemed to have knowledge of the identity of any Subsidiary unless either (A) a
Responsible Officer of the Trustee shall have actual knowledge thereof or (B)
the Trustee shall have received written notice thereof from the Company or any
Holder.

     Section 6.05 May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
6.08 and 6.13, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

     Section 6.06 Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

     Section 6.07 Compensation and Reimbursement.

     The Company agrees:

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

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

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

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

                                       36

     Section 6.08 Disqualification; Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the
meaning of Section 3.10 of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Indenture. To
the extent permitted by the Trust Indenture Act, the Trustee shall not be deemed
to have a conflicting interest with respect to the Securities of any series by
virtue of being Trustee with respect to the Securities of any particular series
of Securities except as may be otherwise provided by the terms of the Securities
of that series.

     Section 6.09 Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be a Person
that is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus of at least $50,000,000. If such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of Federal, State, Territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

     Section 6.10 Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 6.11 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

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

     (d) If at any time:

          (1) the Trustee shall fail to comply with Section 6.08 after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.09 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder, or

                                       37
<PAGE>

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company may remove the Trustee with respect to
any or all Securities, or (ii) subject to Section 5.14, any Holder who has been
a bona fide Holder of a Security for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to any or all
Securities and the appointment of a successor Trustee or Trustees with respect
to such series.

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company shall promptly appoint a
successor Trustee or Trustees with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed
with respect to the Securities of one or more or all of such series and that at
any time there shall be only one Trustee with respect to the Securities of any
particular series) and shall comply with the applicable requirements of Section
6.11. If, within one year after such resignation, removal or incapability, or
the occurrence of such vacancy, a successor Trustee with respect to the
Securities of that or those series shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 6.11, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 6.11, any
Holder who has been a bona fide Holder of a Security of such series for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 1.06. Each notice
of appointment shall include the name of the successor Trustee with respect to
the Securities of such series and the address of its Corporate Trust Office.

     Section 6.11 Acceptance of Appointment by Successor.

     (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver

                                       38
<PAGE>

an instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder, subject nevertheless to its lien, if any, provided for in Section
6.07.

     (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall 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, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

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

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

     Section 6.12 Merger, Conversion, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case

                                       39
<PAGE>

any Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities. In case any Securities shall not have been
authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities, in either its own name or that of its
predecessor Trustee, with the full force and effect which this Indenture
provides for the certificate of authentication of the Trustee.

     Section 6.13 Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of Section 3.11 of the Trust Indenture Act regarding the collection
of such claims against the Company (or any such other obligor). A Trustee that
has resigned or been removed shall be subject to and comply with said Section
3.11 to the extent required thereby.

     Section 6.14 Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities (which may be an Affiliate of the Company)
which shall be authorized to act on behalf of the Trustee to authenticate
Securities issued upon registration of transfer or partial redemption or
repayment thereof or pursuant to Section 3.06, and Securities so authenticated
shall be entitled to the benefits of this Indenture and shall be valid and
obligatory for all purposes as if authenticated by the Trustee hereunder.
Wherever reference is made in this Indenture to the authentication and delivery
of Securities by the Trustee or the Trustee's certificate of authentication,
such reference shall be deemed to include authentication and delivery on behalf
of the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business and in good standing under the
laws of the United States, any State or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of no less than $50,000,000 and subject to supervision or examination by
Federal or State authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

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

                                       40
<PAGE>

any time by giving written notice thereof to the Trustee for such series and to
the Company. The Trustee for any series of Securities may at any time terminate
the agency of an Authenticating Agent for such series by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee of such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders of Securities of the series with respect to which such Authenticating
Agent will serve, as their names and addresses appear in the Security Register.
Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         Except with respect to an Authenticating Agent appointed at the request
of the Company, the Trustee agrees to pay to each Authenticating Agent from time
to time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, pursuant to the
provisions of Section 6.07.

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

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

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; provided, however, that if and so long as the Trustee is Security
Registrar with respect to Securities of a particular series no such list shall
be required with respect to the Securities of such series.

     Section 7.02 Preservation of Information; Communications to Holders.

     (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 7.01 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 7.01 upon receipt of a new list so furnished.

     (b) The rights of 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.

     (c) Every Holder of Securities, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of the
disclosure of information as to the names and addresses of the Holders made
pursuant to the Trust Indenture Act.

     Section 7.03 Reports by Trustee.

     (a) Within 60 days after May 15 of each year commencing with the year

Indenture Act if and to the extent and in the manner provided pursuant thereto.

     (b) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange upon which any
Securities are listed, with the Commission and with the Company. The Company
will notify the Trustee when any Securities are listed on any stock exchange.

     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 summaries
thereof, as may be required pursuant to the Trust Indenture Act at the times and
in the manner provided pursuant to such Act; provided that any such information,
documents or reports required to be filed with the Commission pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, shall be
filed with the Trustee within 15 days after the same is so required to be filed
with the Commission. Delivery of such reports to the Trustee is for
informational purposes only and the Trustee's receipt of such reports shall not
constitute constructive notice of any

                                       42
<PAGE>

information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

     Section 7.05 Holders' Meetings.

     (a) A meeting of Holders of any or all series may be called at any time and
from time to time pursuant to the provisions of this Section 7.05 for any of the
following purposes:

          (1) to give any notice to the Company or to the Trustee for such
     series, or to give any directions to the Trustee for such series, or to
     consent to the waiving of any default hereunder and its consequences, or to
     take any other action authorized to be taken by Holders pursuant to any of
     the provisions of Article V;

          (2) to remove the Trustee for such series and appoint a successor
     Trustee pursuant to the provisions of Article VI;

          (3) to consent to the execution of an indenture or supplemental
     indentures hereto pursuant to the provisions of Section 9.02; and

          (4) to take any other action authorized to be taken by or on behalf of
     the Holders of any specified aggregate principal amount of the Outstanding
     Securities of any one or more or all series, as the case may be, under any
     other provision of this Indenture or under applicable law.

     (b) The Trustee for any series may at any time call a meeting of Holders of
such series to take any action specified in paragraph (a) of this Section 7.05,
to be held at such time or times and at such place or places as the Trustee for
such series shall determine. Notice of every meeting of the Holders of any
series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given to Holders
of such series in the manner and to the extent provided in Section 1.05. Such
notice shall be given not less than 20 days nor more than 90 days prior to the
date fixed for the meeting.

     (c) In case at any time the Company, or the Holders of at least 10% in
aggregate principal amount of the Outstanding Securities of a series or of all
series, as the case may be, shall have requested the Trustee for such series to
call a meeting of Holders of any or all such series by written request setting
forth in reasonable detail the action proposed to be taken at the meeting, and
the Trustee shall not have given the notice of such meeting within 20 days after
the receipt of such request, then the Company or such Holders may determine the
time or times and the place or places for such meetings and may call such
meetings to take any action authorized by giving notice thereof as provided in
the preceding paragraph.

     (d) To be entitled to vote at any meeting of Holders a Person shall be (a)
a Holder of a Security of the series with respect to which such meeting is being
held or (b) a Person appointed by an instrument in writing as agent or proxy by
such Holder. The only Persons who shall be entitled to be present or to speak at
any meeting of Holders shall be the Persons entitled to vote at such meeting and
their counsel and any representatives of the Trustee for the series

                                       43
<PAGE>

with respect to which such meeting is being held and its counsel and any
representatives of the Company and its counsel.

         (e) Notwithstanding any other provisions of this Indenture, the Trustee
for any series may make such reasonable regulations as it may deem advisable for
any meeting of Holders of such series, in regard to proof of the holding of
Securities of such series and of the appointment of proxies, and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate.

         The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of such series as provided in paragraph (c) of this
Section 7.05, in which case the Company or the Holders calling the meeting, as
the case may be, shall in like manner appoint a temporary chairman. A permanent
chairman and a permanent secretary of the meeting shall be elected by a majority
vote of the meeting.

         Subject to the provisos in the definition of "Outstanding," at any
meeting each Holder of a Debt Security of the series with respect to which such
meeting is being held or proxy therefor shall be entitled to one vote for each
$1,000 principal amount (or such other amount as shall be specified as
contemplated by Section 3.01) of Securities of such series held or represented
by him; provided, however, that no vote shall be cast or counted at any meeting
in respect of any Security challenged as not Outstanding and ruled by the
chairman of the meeting to be not Outstanding. The chairman of the meeting shall
have no right to vote other than by virtue of Outstanding Securities of such
series held by him or instruments in writing duly designating him as the person
to vote on behalf of Holders of Securities of such series. Any meeting of
Holders with respect to which a meeting was duly called pursuant to the
provisions of paragraph (b) or (c) of this Section 7.05 may be adjourned from
time to time by a majority of such Holders present and the meeting may be held
as so adjourned without further notice.

         (f) The vote upon any resolution submitted to any meeting of Holders
with respect to which such meeting is being held shall be by written ballots on
which shall be subscribed the signatures of such Holders or of their
representatives by proxy and the serial number or numbers of the Securities held
or represented by them. The permanent chairman of the meeting shall appoint two
inspectors of votes who shall count all votes cast at the meeting for or against
any resolution and who shall make and file with the secretary of the meeting
their verified written reports in duplicate of all votes cast at the meeting. A
record in duplicate of the proceedings of each meeting of Holders shall be
prepared by the secretary of the meeting and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said
notice was transmitted as provided in paragraph (b) of this Section 7.05. The
record shall show the serial numbers of the Securities voting in favor of or
against any resolution. The record shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one of the
duplicates shall be delivered to the Company and the other to the Trustee to be
preserved by the Trustee.

                                       44
<PAGE>

         Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

        (g) Nothing contained in this Section 7.05 shall be deemed or construed
to authorize or permit, by reason of any call of a meeting of Holders or any
rights expressly or impliedly conferred hereunder to make such call, any
hindrance or delay in the exercise of any right or rights conferred upon or
reserved to the Trustee or to any Holder under any of the provisions of this
Indenture or of the Securities of any series.

               (1) in case the Company shall consolidate with or merge into
         another Person or convey, transfer or lease all or substantially all
         of its property or assets to any Person, the Person formed by such
         consolidation or into which the Company is merged or the Person which
         acquires by conveyance or transfer, or which leases, the properties
         and assets of the Company shall be either the Company or a corporation
         or limited liability company, shall be organized and validly existing
         under the laws of the United States, any State thereof or the District
         of Columbia and shall expressly assume, by an indenture supplemental
         hereto executed and delivered to the Trustee, all obligations
         hereunder, including the due and punctual payment of the principal of
         and any premium and interest on all the Securities and the performance
         or observance of every covenant of this Indenture on the part of the
         Company to be performed or observed; and

consolidate with, merge into or transfer all or part of its properties and
assets to the Company.

         Upon any consolidation of the Company with, or merger of the Company
into, any other Person or conveyance, transfer or lease of all or substantially
all of the property or assets of the Company in accordance with Section 8.01,
the successor Person formed by such consolidation or into which the Company is
merged or to which conveyance, transfer or lease of all or substantially all of
its property or assets 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 successor Person had been named as the Company herein,
and thereafter, except in the case of a lease, the predecessor Person shall be
relieved of all obligations and covenants under this Indenture and the
Securities. In the case of a lease, the predecessor Person shall not be released

                                       45
<PAGE>

from its obligations to pay the principal of, premium, if any, and interest on
the Securities. All Securities issued by the successor Person shall in all
respects have the same legal priority as the Securities theretofore or
thereafter authenticated, issued and delivered in accordance with the terms of
this Indenture.

          indenture in any material respect; or

               (2) to change or eliminate any of the provisions of this
          Indenture, provided that any such change or elimination shall become
          effective only when there is no Outstanding Security of any series

          entitled to the benefit of such provision; or

               (3) to secure the Securities; or

          to be for the benefit of less than all series of Securities, stating
          that such covenants are expressly being included solely for


                                       46

         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 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

          Security that would be due and payable upon a declaration of
          acceleration of the Maturity thereof; or adversely affect the right of
          repayment or renewal, if any, at the option of the Holders; or change
          the coin or currency in which the principal of any Security or any
          premium or interest thereon is payable; or change the date on which
          any Security may be redeemed; or adversely affect the rights of any
          Holding to institute suit for the enforcement of any payment of
          principal of or any premium or interest on any Security, in each case
          without the consent of the Holder of each Outstanding Security that
          would be affected thereby (for purposes of this Section 9.02(1) only,
          the term "Security" shall include Securities for which an offer to
          purchase has been accepted by the Company); or

               (2) reduce the aforesaid percentage of Securities, the Holders of
          which are required to consent to any such supplemental indenture, or
          the percentage in aggregate principal amount of the Outstanding
          Securities the consent of the Holders of which is required for any
          waiver of certain past defaults or Events of Default hereunder or the
          consequences thereof, in each case without the consent of the Holders
          of all of the Outstanding Securities.

         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
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

         Section 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.

         Section 9.05 Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         Section 9.06 Reference in Securities to Supplemental Indentures.

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

         Section 9.07 Notice of Supplemental Indenture.

         Promptly after the execution by the Company and the appropriate Trustee
of any supplemental indenture, the Company shall transmit, as provided herein,
to all Holders of any series of the Securities affected thereby, a notice
setting forth in general terms the substance of such supplemental indenture.

         Section 9.08 Subordination Unimpaired.

         No supplemental indenture executed pursuant to this Article shall
directly or indirectly modify the provisions of Article XVI in any manner which
might alter the subordination of the Securities.

                                    COVENANTS

         Section 10.01 Payment of Principal, Premium and Interest.

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

         Section 10.02 Maintenance of Office or Agency.

         The Company will maintain in each Place of Payment an office or agency
where Securities may be presented or surrendered for payment, where Securities
may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company terminates the appointment of a Paying Agent
or Security Registrar or otherwise shall fail to maintain any such required
office or agency, the Company shall use its reasonable best efforts to appoint a
successor Paying Agent or Security Registrar reasonably acceptable to the
Trustee. If the Company fails to maintain a Paying Agent or Security Registrar,
the Trustee will act as such, and the Company hereby appoints the Trustee as its
agent to receive all such presentations, surrenders, notices and demands.

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

         Section 10.03 Money for Securities Payments to Be Held in Trust.

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

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of (and
premium, if any) or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of

                                       49
<PAGE>

the Persons entitled to such principal, premium or interest, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee in
writing of its action or failure so to act.

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

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

               (2) give the Trustee written notice of any default by the Company
          (or any other obligor upon the Securities of that series) in the
          making of any payment of principal (and premium, if any) or interest
          on the Securities of that series; and

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

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

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security of any series and remaining unclaimed for two
years after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in an Authorized Newspaper in
the Borough of Manhattan, The City of New York, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such publication, any unclaimed balance of such money
then remaining will be repaid to the Company.

         Section 10.04 Corporate Existence.

         Subject to Article VIII, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any such

                                       50
<PAGE>

right or franchise if the Company shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Company.

         Section 10.05 Notice of Defaults.

         The Company will give to the Trustee written notice of the occurrence
of an Event of Default within five days after the Company becomes aware of such
occurrence.

         Section 10.06 Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 8.01 or Section 10.04 with
respect to the Securities of any series if, before the time for such compliance,
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive compliance
in such instance or generally waive compliance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

                                  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 in 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, in a manner



                                       51
<PAGE>

which the Trustee deems fair and appropriate, 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 the
Company shall so specify and identify the appropriate Securities, Securities
owned of record and beneficially by the Company or any Subsidiary shall not be
included in the Securities selected for redemption.

         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.

         Section 11.04 Notice of Redemption.

         Notice of redemption shall, unless otherwise specified by the terms of
the Securities to be redeemed, be given not less than 30 nor more than 60 days
prior to the Redemption Date, to each Holder of Securities to be redeemed, in
accordance with Section 1.06.

         All notices of redemption shall state:

          (1) the Redemption Date;

          (2) the Redemption Price;

          (3) the place or places where such Securities are to be surrendered
     for payment of the Redemption Price, which shall be the office or agency of
     the Company in each Place of Payment;

          (4) that payment of the Redemption Price will be made on the surrender
     of such Securities at such place or places of redemption;

          (5) that accrued interest to the Redemption Date will be paid as
     specified in such notice and that from and after the Redemption Date
     interest on such Securities will cease to accrue;

          (6) if less than all the Outstanding Securities of any series are to
     be redeemed (unless all the Securities of such series of a specified tenor
     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;

          (7) in the case of partial redemption of any Securities, that upon
     surrender of such Securities, a new Security or new Securities having the
     same terms will be issued in aggregate principal amount equal to the
     unredeemed portion;

                                       52
<PAGE>

          (8) that redemption is subject to the receipt by the Trustee or a
     Paying Agent prior to the Redemption Date of sufficient funds to make the
     redemption, if such is the case; and

          (9) that the redemption is for a sinking fund, if such is the case.

         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.

         Section 11.05 Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 10.03) 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 will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates 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.

         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. If a Global Security is so surrendered, such new
Security so issued shall be a new Global Security.

                                  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 Mandatory Sinking Fund Payments with
Securities.

         The Company (1) may deliver Outstanding Securities of a series to the
Trustee for cancellation (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 or the Holders, if applicable, 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 mandatory 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 or may
apply Securities of such series which have been previously cancelled; 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 such mandatory
sinking fund and the amount of such mandatory sinking fund payment shall be
reduced accordingly.

         Section 12.03 Redemption of Securities for Mandatory Sinking Fund.

         Not less than 60 days prior to each mandatory 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 mandatory
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 or applying previously cancelled Securities of that series pursuant
to Section 12.02 and the basis for such credit and will also deliver to the
Trustee any Securities to be so delivered which have not theretofore been
delivered to the Trustee. Not less than 30 days before each such mandatory
sinking fund payment date, the Trustee shall select the Securities to be
redeemed upon such mandatory sinking fund payment date in the manner specified
in Section 11.02 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
11.03. Such notice having been duly given, the redemption of such

                                       54
<PAGE>

Securities shall be made upon the terms and in the manner stated in Sections
11.04, 11.05 and 11.06.

         Section 13.01 Applicability of Article.

         Securities of any series that are repayable before their Stated

Securities of any series) in accordance with this Article.

         Section 13.02 Notice of Repayment Date.

         Notice of any Repayment Date with respect to Securities of any series

in accordance with Sections 1.05 and 1.06, respectively.

         The notice as to Repayment Date shall state:

               (1)  the Repayment Date;

               (2)  the Repayment Price;

               (3)  the place or places where such Securities are to be
         surrendered for payment of the Repayment Price, which shall be the
         office or agency of the Company in each Place of Payment, and the date
         by which Securities must be so surrendered in order to be repaid;

               (4) a description of the procedure which a Holder must follow to
         exercise a repayment right; and

               (5) that exercise of the option to elect repayment is
         irrevocable.

         No failure of the Company to give the foregoing notice shall limit any
Holder's right to exercise a repayment right.

         Section 13.03 Deposit of Repayment Price.

         On or prior to any Repayment Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying

money sufficient to pay the Repayment Price of and (except if the Repayment Date
shall be an Interest Payment Date) accrued interest on, all the Securities of
such series which are to be repaid on that date.

         The form of option to elect repayment having been delivered as
specified in the form of Security for such series as provided in Section 2.01,
the Securities so to be repaid shall, on the Repayment Date, become due and
payable at the Repayment Price applicable thereto, and from and after such date
(unless the Company shall default in the payment of the Repayment Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender
of any such Security for repayment in accordance with said notice, such Security
shall be paid by the Company at the Repayment Price, together with accrued
interest to the Repayment Date; provided, however, that, unless otherwise
specified as contemplated by Section 3.01, installments of interest whose Stated
Maturity is on or prior to such Repayment Date will be payable to the Holders of
such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Date according to their terms and
the provisions of Section 3.07.

         If any Security to be repaid shall not be so paid upon surrender
thereof for repayment, the principal shall, until paid, bear interest from the

Section 10.02 (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 unrepaid portion of the principal of the Security so

defeasance of the Securities of a series under Section 14.02 or (b) covenant
defeasance of the Securities of a series under Section 14.03, then the

other provisions of this Article XIV, shall be applicable to the Securities of
such series, and the Company may at its option at any time with respect to the
Securities of such series, elect to have either Section 14.02 (if applicable) or
Section 14.03 (if applicable) be applied to the

                                       56

Outstanding Securities of such 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 above option applicable to this
Section with respect to the Outstanding Securities of a particular series, the
Company shall be deemed to have been discharged from its obligations with
respect to the Outstanding Securities of such series (except for certain
obligations to register the transfer or exchange of Securities of such series,
to replace stolen, lost or mutilated Securities of such series, and to maintain
paying agencies) on and after the date the conditions precedent set forth below
are satisfied (hereinafter, "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 such Securities and this
Indenture insofar as such Securities are concerned (and the Trustee, at the
expense of the Company and upon Company Request, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of Outstanding Securities of such series to receive, solely from the
trust fund described in Section 14.04 as more fully set forth in such Section,
payments of the principal of and any premium and interest on such Securities
when such payments are due, (B) the Company's obligations with respect to such
Securities under Section 3.04, 3.05, 3.06, 6.07, 10.02 and 10.03 and such
obligations as shall be ancillary thereto, (C) the rights, powers, trusts,
duties, immunities and other provisions in respect of the Trustee hereunder and
(D) this Article XIV. Subject to compliance with this Article XIV, the Company
may exercise its option under this Section 14.02 notwithstanding the prior
exercise of its option under Section 14.03 with respect to the Securities of
such series.

         Section 14.03 Covenant Defeasance.

         Upon the Company's exercise of the above option applicable to this
Section with respect to the Outstanding Securities of a particular series, the
Company shall be released from its obligations under Sections 8.01 and 10.04
(and any other covenant applicable to such Securities that is determined
pursuant to Section 3.01 to be subject to covenant defeasance under this
Section) and the occurrence of an event specified in Clause (4) of Section 5.01
with respect to any of Sections 8.01 or 10.04 (and any other Event of Default
applicable to such Securities that is determined pursuant to Section 3.01 to be
subject to covenant defeasance under this Section) shall not be deemed to be an
Event of Default with respect to the Outstanding Securities of such series on
and after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"). For this purpose, such covenant defeasance means that,
with respect to the Outstanding Securities of such series, the Company may omit
to comply with and shall have no liability in respect of any term, condition,
limitation or restrictive covenant set forth in any such Section or Clause
whether directly or indirectly by reason of any reference elsewhere herein to
any such Section or Clause or by reason of any reference in any such Section or
Clause to any other provision herein or in any other document, including any
supplement hereto, any Board Resolution or Officers' Certificate delivered
hereto but the remainder of this Indenture and such Securities shall be
unaffected thereby.

         Section 14.04 Conditions to Defeasance or Covenant Defeasance.

         The following shall be the conditions precedent to application of
either Section 14.02 or Section 14.03 to the Outstanding Securities of a
particular series:

               (1) The Company shall irrevocably have deposited or caused to be
          deposited with the Trustee (or another trustee satisfying the
          requirements of Section 6.09 who shall agree 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 such Securities, (A) money in an amount, or (B) U.S.
          Government Obligations which 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, sufficient,
          without reinvestment, in the opinion of a nationally recognized firm
          of independent public accountants expressed in a written certification
          thereto delivered to the Trustee, to pay and discharge, and which
          shall be applied by the Trustee (or other qualifying trustee) to pay
          and discharge, (i) the principal of and any premium, if any, and
          interest on the Outstanding Securities of such series on the maturity
          of such principal, premium or interest and (ii) any mandatory sinking
          fund payments or analogous payments applicable to the Outstanding
          Securities of such series on the day on which such payments are due in
          accordance with the terms of this Indenture and of such Securities.
          Before such a deposit, the Company may make arrangements satisfactory
          to the Trustee for the redemption of Securities at a future date or
          dates in accordance with Article XI, which shall be given effect in
          applying the foregoing. For this purpose, "U.S. Government
          Obligations" means securities that are (x) direct obligations of the
          United States for the payment of which its full faith and credit is
          pledged or (y) obligations of a Person controlled or supervised by and
          acting as an agency or instrumentality of the United States the timely
          payment of which is unconditionally guaranteed as a full faith and
          credit obligation by the United States, which, in either case, are not
          callable or redeemable at the option of the issuer thereof, and shall
          also include a 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 such U.S. Government Obligation or a
          specific payment of principal of or interest on any such U.S.
          Government Obligation held by such custodian for the account of the
          holder of such depositary receipt, 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 of or interest on the
          U.S. Government Obligation evidenced by such depositary receipt.

               (2) No Event of Default or event which with notice or lapse of
          time or both would become an Event of Default with respect to the
          Securities of such series shall have occurred and be continuing (A) on
          the date of such deposit or (B) insofar as subsections 5.01(7) and (8)
          are concerned, at any time during the period ending on the 91st day
          after the date of such deposit or, if longer, ending on the day
          following the expiration of the longest preference period applicable
          to the Company in respect of such deposit (it being



                                       58
<PAGE>

          understood that the condition in this condition shall not be deemed
          satisfied until the expiration of such period).

               (3) Such defeasance or covenant defeasance shall not (A) cause
          the Trustee for the Securities of such series to have a conflicting
          interest as defined in Section 6.08 or for purposes of the Trust
          Indenture Act with respect to any securities of the Company or (B)
          result in the trust arising from such deposit to constitute, unless it
          is qualified as, a regulated investment company under the Investment
          Company Act of 1940, as amended.

               (4) Such defeasance or covenant defeasance shall not result in a
          breach or violation of, or constitute a default under, this Indenture
          or any other material agreement or instrument to which the Company is
          a party or by which it is bound.

               (5) In the case of an election under Section 14.02, the Company
          shall have delivered to the Trustee an Opinion of Counsel stating that
          (x) the Company has received from, or there has been published by, the
          Internal Revenue Service a ruling, or (y) since the date of this
          Indenture there has been a change in the applicable Federal income tax
          law, in either case to the effect that, and based thereon such opinion
          shall confirm that, the Holders of the Outstanding Securities of such
          series will not recognize income, gain or loss for United States
          federal income tax purposes as a result of such deposit, defeasance
          and discharge and will be subject to United States federal income tax
          on the same amounts, in the same manner and at the same times as would
          have been the case if such deposit, defeasance and discharge had not
          occurred.

               (6) 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 income, gain or loss for United States federal
          income tax purposes as a result of such covenant defeasance and will
          be subject to United States federal income tax on the same amounts, in
          the same manner and at the same times as would have been the case if
          such deposit and covenant defeasance had not occurred.

               (7) Such defeasance or covenant defeasance shall be effected in
          compliance with any additional terms, conditions or limitations which
          may be imposed on the Company in connection therewith pursuant to
          Section 3.01.

               (8) The Company shall have delivered to the Trustee an Officers'
          Certificate and an Opinion of Counsel, each stating that all
          conditions precedent provided for relating to either the defeasance
          under Section 14.02 or the covenant defeasance under Section 14.03 (as
          the case may be) have been complied with.

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

         Subject to the provisions of the last paragraph of Section 10.03, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee - collectively, for purposes for
this Section 14.05, the "Trustee") pursuant to Section 14.04 in respect of the
Outstanding Securities of such series shall be held in trust and

                                       59
<PAGE>

applied by the Trustee, in accordance with the provisions of such Securities and
this Indenture, to the payment, either directly or through any Paying Agent (but
not including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal, premium and interest, but such money need not
be segregated from other funds except to the extent required by law.

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

         Anything herein 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 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent defeasance or covenant defeasance.

         Section 14.06 Reinstatement.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 14.02 or 14.03 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 until such time as the Trustee or Paying Agent is permitted to
apply all such money in accordance with Section 14.02 or 10.03; provided,
however, that if the Company makes any payment of the principal of or any
premium or interest on any such Security following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money held by the Trustee or
the Paying Agent.

                                  ARTICLE XV.

                           IMMUNITY OF INCORPORATORS,
                      STOCKHOLDERS, OFFICERS AND DIRECTORS

          Section 15.01 Immunity of Incorporators, Stockholders, Officers and
Directors.

         No recourse under or upon any obligation, covenant or agreement of this
Indenture, or of any Security, or for any claim based thereon or otherwise in
respect thereof, shall be had against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly understood that this Indenture and the
obligations issued hereunder are solely corporate obligations, and that no
personal liability whatever shall attach to, or is or shall be incurred by, the
incorporators, stockholders, officers or directors, as such, of the Company or
any successor corporation, or any of them, because of the creation of the



                                       60
<PAGE>

indebtedness hereby authorized, or under or by this Indenture or in any of the
Securities or implied therefrom; and that any and all such personal liability of
every name and nature, either at common law or in equity or by constitution or
statute, of, and any and all such rights and claims against, every such
incorporator, stockholder, officer or director, as such, because of the creation
of the indebtedness hereby authorized, or under or by reason of the obligations,
covenants or agreements contained in this Indenture or in any of the Securities
or implied therefrom are hereby expressly waived and released as a condition of,
and as a consideration for, the execution of this Indenture and the issue of
such Securities.

                                  ARTICLE XVI.
                           SUBORDINATION OF SECURITIES

         Section 16.01 Securities Subordinate to Senior Debt.

         The Company covenants and agrees that anything in this Indenture or the
Securities of any series to the contrary notwithstanding, the indebtedness
evidenced by the Securities of each series is subordinate and junior in right of
payment to all Senior Debt to the extent provided herein, and each Holder of
Securities of each series, by his acceptance thereof, likewise covenants and
agrees to the subordination herein provided and shall be bound by the provisions
hereof. Senior Debt shall continue to be Senior Debt and entitled to the
benefits of these subordination provisions irrespective of any amendment,
modification or waiver of any term of the Senior Debt or extension or renewal of
the Senior Debt.

         In the event that the Company shall default in the payment of any
principal of (or premium, if any) or interest on any Senior Debt when the same
becomes due and payable, whether at maturity or at a date fixed for repayment or
by declaration of acceleration or otherwise, then, upon written notice of such
default to the Company by the holders of Senior Debt or any trustee therefor or
representative thereof, unless and until such default shall have been cured or
waived or shall have ceased to exist, no direct or indirect payment (in cash,
property, securities, by set-off or otherwise) shall be made or agreed to be
made on account of the principal of (or premium, if any) or interest on any of
the Securities, or in respect of any redemption, retirement, purchase or other
acquisition of any of the Securities.

         In the event of

         (a) any insolvency, bankruptcy, receivership, liquidation,
reorganization, readjustment, composition or other similar proceeding relating
to the Company, its creditors or its property,

         (b) any proceeding for the liquidation, dissolution or other winding
up of the Company, voluntary or involuntary, whether or not involving insolvency
or bankruptcy proceedings,

         (c) any assignment by the Company for the benefit of creditors, or

         (d) any other marshalling of the assets of the Company,

                                       61
<PAGE>

all Senior Debt (including any interest thereon accruing after the commencement
of any such proceedings) shall first be paid in full before any payment or
distribution, whether in cash, securities or other property, shall be made to
any Holder of any of the Securities on account thereof. Any payment or
distribution, whether in cash, securities or other property (other than
securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in these subordination provisions with respect to the
indebtedness evidenced by the Securities, to the payment of all Senior Debt at
the time outstanding and to any securities issued in respect thereof under any
such plan of reorganization or readjustment), which would otherwise (but for
these subordination provisions) be payable or deliverable in respect of the
Securities of any series shall be paid or delivered directly to the holders of
Senior Debt in accordance with the priorities then existing among such holders
until all Senior Debt (including any interest thereof accruing after the
commencement of any such proceedings) shall have been paid in full. In the event
of any such proceeding, after payment in full of all sums owing with respect to
Senior Debt, the Holders of the Securities, together with the holders of any
obligations of the Company ranking on a parity with the Securities, shall be
entitled to be paid from the remaining assets of the Company the amounts at the
time due and owing on account of unpaid principal of (and premium, if any) and
interest on the Securities and such other obligations before any payment or
other distribution, whether in cash, property or otherwise, shall be made on
account of any capital stock or any obligations of the Company ranking junior to
the Securities and such other obligations.

         In the event that, notwithstanding the foregoing, any payment or
distribution of any character, whether in cash, securities or other property
(other than securities of the Company or any other corporation provided for by a
plan of reorganization or readjustment the payment of which is subordinate, at
least to the extent provided in these subordination provisions with respect to
the indebtedness evidenced by the Securities, to the payment of all Senior Debt
at the time outstanding and to any securities issued in respect thereof under
any such plan of reorganization or readjustment), or any security shall be
received by the Trustee or any Holder in contravention of any of the terms
hereof, such payment or distribution or security shall be received in trust for
the benefit of, and shall be paid over or delivered and transferred to, the
holders of the Senior Debt at the time outstanding in accordance with the
priorities then existing among such holders for application to the payment of
all Senior Debt remaining unpaid, to the extent necessary to pay all such Senior
Debt in full. In the event of the failure of the Trustee or any Holder to
endorse or assign any such payment, distribution or security, each holder of
Senior Debt is hereby irrevocably authorized to endorse or assign the same.

         No present or future holder of any Senior Debt shall be prejudiced in
the right to enforce subordination of the indebtedness evidenced by the
Securities by any act or failure to act on the part of the Company. Nothing
contained herein shall impair, as between the Company and the Holders of
Securities of each series, the obligation of the Company to pay to such Holders
the principal of (and premium, if any) and interest on such Securities or
prevent the Trustee or the Holder from exercising all rights, powers and
remedies otherwise permitted by applicable law or hereunder upon a Default or
Event hereunder, all subject to the rights of the holders of the Senior Debt to
receive cash, securities or other property otherwise payable or deliverable to
the Holders.

         Senior Debt shall not be deemed to have been paid in full unless the
holders thereof shall have received cash, securities or other property equal to
the amount of such Senior Debt then

                                       62
<PAGE>

outstanding. Upon the payment in full of all Senior Debt, the Holders of
Securities of each series shall be subrogated to all rights of any holders of
Senior Debt to receive any further payments or distributions applicable to the
Senior Debt until the indebtedness evidenced by the Securities of such series
shall have been paid in full, and such payments or distributions received by
such Holders, by reason of such subrogation, of cash, securities or other
property which otherwise would be paid or distributed to the holders of Senior
Debt, shall, as between the Company and its creditors other than the holders of
Senior Debt, on the one hand, and such Holders, on the other hand, be deemed to
be a payment by the Company on account of Senior Debt, and not on account of the
Securities of such series.

         The provisions of this Section 16.01 shall not impair any right,
interests, remedies or powers of any secured creditor of the Company in respect
of any security interest the creation of which is not prohibited by the
provisions of this Indenture.

         The securing of any obligations of the Company, otherwise ranking on a
parity with the Securities or ranking junior to the Securities, shall not be
deemed to prevent such obligations from constituting, respectively, obligations
ranking on a parity with the Securities or ranking junior to the Securities.

         Section 16.02 Trustee and Holders of Securities May Rely on Certificate
of Liquidating Agent; Trustee May Require Further Evidence as to Ownership of
Senior Debt; Trustee Not Fiduciary to Holders of Senior Debt.

         Upon any payment or distribution of assets of the Company referred to
in this Article XVI, the Trustee and the Holders shall be entitled to rely upon
an order or decree made by any court of competent jurisdiction in which such
dissolution or winding up or liquidation or reorganization or arrangement
proceedings are pending or upon a certificate of the trustee in bankruptcy,
receiver, assignee for the benefit of creditors or other Person making such
payment or distribution, delivered to the Trustee or to the Holders, for the
purpose of ascertaining the Persons entitled to participate in such
distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article
XVI. In the absence of any such bankruptcy trustee, receiver, assignee or other
Person, the Trustee shall be entitled to rely upon a written notice by a Person
representing himself to be a holder of Senior Debt (or a trustee or
representative on behalf of such holder) as evidence that such Person is a
holder of such Senior Debt (or is such a trustee or representative). In the
event that the Trustee determines, in good faith, that further evidence is
required with respect to the right of any Person as a holder of Senior Debt to
participate in any payments or distributions pursuant to this Article XVI, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Debt held by such Person,
as to the extent to which such Person is entitled to participate in such payment
or distribution, and as to other facts pertinent to the rights of such Person
under this Article XVI, and if such evidence is not furnished, the Trustee may
defer any payment to such Person pending judicial determination as to the right
of such Person to receive such payment. With respect to the holders of Senior
Debt, the Trustee undertakes to perform or to observe only such of its covenants
and obligations as are specifically set forth in this Article, and no implied
covenants or obligations with respect to the holders of Senior Debt shall be
read into this Indenture against the Trustee. The Trustee shall not be

                                       63
<PAGE>

deemed to owe any fiduciary duty to the holders of Senior Debt and, subject to
the provisions of Section 6.01, the Trustee shall not be liable to any holder of
Senior Debt if it shall in good faith pay over or deliver to Holders of
Securities, the Company or any other Person moneys or assets to which any holder
of Senior Debt shall be entitled by virtue of this Article or otherwise.

         Section 16.03 Payment Permitted If No Default.

         Nothing contained in this Article XVI or elsewhere in this Indenture,
or in any of the Securities, shall prevent (a) the Company at any time, except
during the pendency of any dissolution, winding up, liquidation or
reorganization proceedings referred to in, or under the conditions described in,
Section 16.01, from making payments of the principal of (or premium, if any) or
interest on the Securities, or (b) the application by the Trustee or any Paying
Agent of any moneys deposited with it hereunder to payments of the principal of
(or premium, if any) or interest on the Securities if the Trustee or such Paying
Agent, as the case may be, did not have the written notice provided for in
Section 16.04 by the times referred to therein of any event prohibiting the
making of such deposit or exchange, and the Trustee or any Paying Agent shall
not be affected by any notice to the contrary received by it on or after such
times.

         Section 16.04 Trustee Not Charged with Knowledge of Prohibition.

         Anything in this Article XVI or elsewhere in this Indenture contained
to the contrary notwithstanding, the Trustee shall not at any time be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment of money to or by the Trustee and shall be entitled conclusively to
assume that no such facts exist and that no event specified in Section 16.01 has
happened, until the Trustee shall have received an Officers' Certificate to that
effect or notice in writing to that effect signed by or on behalf of the holder
or holders, or their representatives, of Senior Debt who shall have been
certified by the Company or otherwise established to the reasonable satisfaction
of the Trustee to be such holder or holders or representatives or from any
trustee under any indenture pursuant to which such Senior Debt shall be
outstanding; provided, however, that, if prior to the third Business Day
preceding the date upon which by the terms hereof any money becomes payable
(including, without limitation, the payment of either the principal of or
interest on any Security), or in the event of the execution of an instrument
pursuant to Section 4.01 acknowledging satisfaction and discharge of this
Indenture, then if prior to the second Business Day preceding the date of such
execution, the Trustee or any Paying Agent shall not have received with respect
to such money the Officers' Certificate or notice provided for in this Section
16.04, then, anything herein contained to the contrary notwithstanding, the
Trustee or such Paying Agent shall have full power and authority to receive such
money and apply the same to the purpose for which they were received and shall
not be affected by the notice to the contrary which may be received by it on or
after such date. The Company shall give prompt written notice to the Trustee and
to the Paying Agent of any facts which would prohibit the payment of money to or
by the Trustee or any Paying Agent.

         Section 16.05 Trustee to Effectuate Subordination.

         Each Holder of Securities by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination

as between such Holder and holders of Senior Debt as provided in this Article
and appoints the Trustee its attorney-in-fact for any and all such purposes.

         Section 16.06 Rights of Trustee as Holder of Senior Debt.

         The Trustee shall be entitled to all the rights set forth in this
Article with respect to any Senior Debt which may at the time be held by it, to
the same extent as any other holder of Senior Debt, and nothing in this
Indenture shall deprive the Trustee of any of its rights as such holder;
provided, however, that nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 6.07.

         Section 16.07 Article Applicable to Paying Agents.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context shall otherwise
require) be construed as extending to and including such Paying Agent within its
meaning as fully for all intents and purposes as if the Paying Agent were named
in this Article in addition to or in place of the Trustee; provided, however,
that Sections 16.04 and 16.06 shall not apply to the Company or any Affiliate of
the Company if the Company or such Affiliate acts as Paying Agent.

         Section 16.08 Subordination Rights Not Impaired by Acts or Omissions
of the Company or Holders of Senior Debt.

         No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof which any such holder may have or be
otherwise charged with. The holders of Senior Debt may, at any time or from time
to time and in their absolute discretion, change the manner, place or terms of
payment, change or extend the time of payment of, or renew or alter, any such
Senior Debt, or amend or supplement any instrument pursuant to which any such
Senior Debt is issued or by which it may be secured, or release any security
therefor, or exercise or refrain from exercising any other of their rights under
the Senior Debt, including, without limitation, the waiver of default
thereunder, all without notice to or assent from the Holders of the Securities
or the Trustee and without affecting the obligations of the Company, the Trustee
or the Holders of the Securities under this Article.
