covered by an opinion of, any specified Person, it is not necessary that all

such Person may certify or give an opinion with respect to some matters and one

or give an opinion as to such matters in one or several documents.

          Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which such officer's certificate or opinion are
based are erroneous. Any such certificate or Opinion of Counsel may be based,
insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

          Whenever, subsequent to the receipt by the Trustee of any Board
Resolution, Officer's Certificate, Opinion of Counsel or other document or
instrument, a clerical, typographical or other inadvertent or unintentional
error or omission shall be discovered therein, a new document or instrument may
be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates of
the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is
substituted. Anything in this Indenture to the contrary notwithstanding, if any
such corrective document or instrument indicates that action has been taken by
or at the request of the Company which could not have been taken had the
original document or instrument not contained such error or omission, the action
so taken shall not be invalidated or otherwise rendered ineffective but shall be
and remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith. Without limiting the generality of

<PAGE>
                                      -9-

the foregoing, any Securities issued under the authority of such defective
document or instrument shall nevertheless be the valid obligations of the
Company entitled to the benefits of this Indenture equally and ratably with all
other Outstanding Securities, except as aforesaid.

SECTION 104.  Acts of Holders.

     instruments of substantially similar tenor signed by such Holders in person
     or by an agent duly appointed in writing or, alternatively, may be embodied
     in and evidenced by the record of Holders voting in favor thereof, either
     in person or by proxies duly appointed in writing, at any meeting of
     Holders duly called and held in accordance with the provisions of Article
     Thirteen, or a combination of such instruments and any such record. Except
     as herein otherwise expressly provided, such action shall become effective
     when such instrument or instruments or record or both are delivered to the
     Trustee and, where it is hereby expressly required, to the Company. Such
     instrument or instruments and any such record (and the action embodied
     therein and evidenced thereby) are herein sometimes referred to as the
     "Act" of the Holders signing such instrument or instruments and so voting
     at any such meeting. Proof of execution of any such instrument or of a
     writing appointing any such agent, or of the holding by any Person of a
     Security, shall be sufficient for any purpose of this Indenture and
     (subject to Section 901) conclusive in favor of the Trustee and the
     Company, if made in the manner provided in this Section. The record of any
     meeting of Holders shall be proved in the manner provided in Section 1306.

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

          (c) The principal amount (except as otherwise contemplated in clause
     (y) of the first proviso to the definition of Outstanding) and serial
     numbers of Securities held by any Person, and the date of holding the same,
     shall be proved by the Security Register.

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

<PAGE>
                                      -10-

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

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

          (g) If the Company shall solicit from Holders any request, demand,
     authorization, direction, notice, consent, waiver or other Act, the Company
     may, at its option, fix in advance a record date for the determination of
     Holders entitled to give such request, demand, authorization, direction,
     notice, consent, waiver or other Act, but the Company shall have no
     obligation to do so. If such a record date is fixed, such request, demand,
     authorization, direction, notice, consent, waiver or other Act may be given
     before or after such record date, but only the Holders of record at the
     close of business on the record date shall be deemed to be Holders for the
     purposes of determining whether Holders of the requisite proportion of the
     Outstanding Securities have authorized or agreed or consented to such
     request, demand, authorization, direction, notice, consent, waiver or other
     Act, and for that purpose the Outstanding Securities shall be computed as
     of the record date.

SECTION 105.  Notices, etc. to Trustee and Company.

          Any request, demand, authorization, direction, notice, consent,
election, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with, the
Trustee by any Holder or by the Company, or 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 delivered personally to an officer or
other responsible employee of the addressee at the applicable location set forth
below or at such other location as such party may from time to time designate by
written notice, or transmitted by facsimile transmission or other direct written
electronic means to such telephone number or other electronic communications
address as the parties hereto shall from time to time designate by written
notice, or transmitted by certified or registered mail, charges prepaid, to the
applicable address set forth below or to such other address as either party
hereto may from time to time designate by written notice:

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

SECTION 106.  Notice to Holders of Securities; Waiver.

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

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

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

SECTION 107.  Conflict with Trust Indenture Act.

          If any provision of this Indenture limits, qualifies or conflicts with
another provision hereof which is required or deemed to be included in this
Indenture by, or is otherwise governed by, any of the provisions of the Trust
Indenture Act, such other provision shall control; and if any provision hereof
otherwise conflicts with the Trust Indenture Act, the Trust Indenture Act shall

<PAGE>
                                      -12-

control unless otherwise provided as contemplated by Section 301 with respect to
any series of Securities.

SECTION 108.  Effect of Headings and Table of Contents.

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

SECTION 109.  Successors and Assigns.

          All covenants and agreements in this Indenture by the Company and
Trustee shall bind their respective successors and assigns, whether so expressed
or not.

SECTION 110.  Separability Clause.

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

SECTION 111.  Benefits of Indenture.

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

SECTION 112.  Governing Law.

          THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, EXCEPT TO THE EXTENT THAT
THE LAW OF ANY OTHER JURISDICTION SHALL BE MANDATORILY APPLICABLE.

SECTION 113.  Legal Holidays.

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

registered form without coupons. The definitive Securities shall be produced in
such manner as shall be determined by the officers executing such Securities, as
evidenced by their execution thereof.

Company Order or that such terms shall be determined by the Company or its
agents in accordance with procedures specified in a Company Order as
contemplated by the clause (b) of Section 303.

SECTION 302.  Denominations.

          Unless otherwise provided as contemplated by Section 301 with respect

SECTION 303.  Execution, Authentication, Delivery and Dating.

          Unless otherwise provided as contemplated by Section 301 with respect

corporate seal of the Company affixed thereto or reproduced thereon attested by
any other Authorized Officer or by the Secretary or an Assistant Secretary of

          Securities bearing the manual or facsimile signatures of individuals
who were at the time of execution Authorized Officers or the Secretary or an
Assistant Secretary of the Company shall bind the Company, notwithstanding that
such individuals or any of them have ceased to hold such offices prior to the

          The Trustee shall authenticate and deliver Securities of a series, for
original issue, at one time or from time to time in accordance with the Company
Order referred to below, upon receipt by the Trustee of:

     terms of such series, as provided in Sections 201 and 301;

          (b) a Company Order requesting the authentication and delivery of such

<PAGE>
                                      -18-

     indenture or Board Resolution, all as contemplated by Sections 201 and 301,
     either (i) establishing such terms or (ii) in the case of Securities of a
     series subject to a Periodic Offering, specifying procedures, acceptable to
     the Trustee, by which such terms are to be established (which procedures
     may provide, to the extent acceptable to the Trustee, for authentication
     and delivery pursuant to oral or electronic instructions from the Company
     or any agent or agents thereof, which oral instructions are to be promptly
     confirmed electronically or in writing), in either case in accordance with
     the instrument or instruments delivered pursuant to clause (a) above;

          (c) the Securities of such series, executed on behalf of the Company
     by an Authorized Officer;

          (d) an Opinion of Counsel to the effect that:

               (i)  the form or forms of such Securities have been duly
                    authorized by the Company and have been established in
                    conformity with the provisions of this Indenture;

               (ii) the terms of such Securities have been duly authorized by
                    the Company and have been established in conformity with the
                    provisions of this Indenture; and

              (iii) such Securities, when authenticated and delivered by the
                    Trustee and issued and delivered by the Company in the
                    manner and subject to any conditions specified in such
                    Opinion of Counsel, will have been duly issued under this
                    Indenture and will constitute valid and legally binding
                    obligations of the Company, entitled to the benefits
                    provided by this Indenture, and enforceable in accordance
                    with their terms, subject, as to enforcement, to laws
                    relating to or affecting generally the enforcement of
                    creditors' rights, including, without limitation, bankruptcy
                    and insolvency laws and to general principles of equity
                    (regardless of whether such enforceability is considered in
                    a proceeding in equity or at law);

provided, however, that, with respect to Securities of a series subject to a
Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel only once at or prior to the time of the first authentication of such
Securities (provided that such Opinion of Counsel addresses the authentication
and delivery of all Securities of such series) and that in lieu of the opinions
described in clauses (ii) and (iii) above Counsel may opine that:

               (x) when the terms of such Securities shall have been established
          pursuant to a Company Order or Orders or pursuant to such procedures
          (acceptable to the Trustee) as may be specified from time to time by a
          Company Order or Orders, all as contemplated by and in accordance with
          the instrument or instruments delivered pursuant to clause (a) above,
          such terms will have been duly authorized by the Company and will have

                                      -19-

          been established in conformity with the provisions of this Indenture;
          and

               (y) such Securities, when authenticated and delivered by the
          Trustee in accordance with this Indenture and the Company Order or
          Orders or specified procedures referred to in paragraph (x) above and
          issued and delivered by the Company in the manner and subject to any
          conditions specified in such Opinion of Counsel, will have been duly
          issued under this Indenture and will constitute valid and legally
          binding obligations of the Company, entitled to the benefits provided
          by the Indenture, and enforceable in accordance with their terms,
          subject, as to enforcement, to laws relating to or affecting generally
          the enforcement of creditors' rights, including, without limitation,
          bankruptcy and insolvency laws, and to general principles of equity
          (regardless of whether such enforceability is considered in a
          proceeding in equity or at law).

          With respect to Securities of a series subject to a Periodic Offering,
the Trustee may conclusively rely, as to the authorization by the Company of any
of such Securities, the form, terms thereof and the legality, validity, binding
effect and enforceability thereof, and compliance of the authentication and
delivery thereof with the terms and conditions of this Indenture, upon the
Opinion of Counsel and other documents delivered pursuant to Sections 201 and
301 and this Section, as applicable, at or prior to the time of the first
authentication of Securities of such series unless and until such opinion or
other documents have been superseded or revoked or expire by their terms. In
connection with the authentication and delivery of Securities of a series
subject to a Periodic Offering, the Trustee shall be entitled to assume that the
Company's instructions to authenticate and deliver such Securities do not
violate any applicable law or any applicable rule, regulation or order of any
Governmental Authority having jurisdiction over the Company.

          If the form or terms of the Securities of any series have been
established by or pursuant to a Board Resolution or an Officer's Certificate as
permitted by Sections 201 or 301, the Trustee shall not be required to
authenticate such Securities if the issuance of such Securities pursuant to this
Indenture will materially or adversely 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.

          Unless otherwise specified as contemplated by Section 301 with respect
to any series of Securities, or any Tranche thereof, each Security shall be
dated the date of its authentication.

          Unless otherwise specified as contemplated by Section 301 with respect
to any series of Securities, 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 or an Authenticating Agent by manual
signature, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder to the Company, or any Person acting on its behalf, but

<PAGE>
                                      -20-

shall never have been issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 309
together with a written statement (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) stating that such Security has
never been issued and sold by the Company, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits hereof.

SECTION 304.  Temporary Securities.

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

          Unless otherwise specified as contemplated by Section 301 with respect
to the Securities of any series, or any Tranche thereof, after the preparation
of definitive Securities of such series or Tranche, the temporary Securities of
such series or Tranche shall be exchangeable, without charge to the Holder
thereof, for definitive Securities of such series or Tranche upon surrender of
such temporary Securities at the office or agency of the Company maintained
pursuant to Section 602 in a Place of Payment for such Securities. Upon such
surrender of temporary Securities for such exchange, the Company shall, except
as aforesaid, execute and the Trustee shall authenticate and deliver in exchange
therefor definitive Securities of the same series and Tranche of authorized
denominations and of like tenor and aggregate principal amount.

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

SECTION 305.  Registration, Registration of Transfer and Exchange.

          The Company shall cause to be kept in each office designated pursuant
to Section 602, with respect to the Securities of each series, a register (all
registers kept in accordance with this Section being collectively 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 Securities of
such series, or any Tranche thereof, and the registration of transfer thereof.
The Company shall designate one Person to maintain the Security Register for the
Securities of each series on a consolidated basis, and such Person is referred
to herein, with respect to such series, as the "Security Registrar." Anything
herein to the contrary notwithstanding, the Company may designate one or more of
its offices as an office in which a register with respect to the Securities of
one or more series shall be maintained, and the Company may designate itself the
Security Registrar with respect to one or more of such series. The Security

<PAGE>
                                      -21-

Register shall be open for inspection by the Trustee and the Company at all
reasonable times.

          Except as otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, or any Tranche thereof, upon surrender
for registration of transfer of any Security of such series or Tranche at the
office or agency of the Company maintained pursuant to Section 602 in a Place of
Payment for such series or Tranche, 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 and Tranche, of
authorized denominations and of like tenor and aggregate principal amount.

          Except as otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, or any Tranche thereof, any Security of
such series or Tranche may be exchanged at the option of the Holder, for one or
more new Securities of the same series and Tranche, of authorized denominations
and of like tenor and aggregate principal amount, upon surrender of the
Securities to be exchanged at any such office or agency. Whenever any Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Securities which the Holder making the
exchange is entitled to receive.

          All Securities delivered upon any registration of transfer or exchange
of Securities shall be valid obligations of the Company, evidencing the same
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, the Trustee or the
Security Registrar) be duly endorsed or shall be accompanied by a written
instrument of transfer in form satisfactory to the Company, the Trustee or the
Security Registrar, as the case may be, duly executed by the Holder thereof or
his attorney duly authorized in writing.

          Unless otherwise specified as contemplated by Section 301 with respect
to Securities of any series, or any Tranche thereof, 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 304, 406 or
1206 not involving any transfer.

          The Company shall not be required to execute or to provide for the
registration of transfer of or the exchange of (a) Securities of any series, or
any Tranche thereof, during a period of 15 days immediately preceding the date
notice is to be given identifying the serial numbers of the Securities of such
series or Tranche called for redemption or (b) any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

                                      -22-

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

          If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and Tranche, 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 (a)
evidence to their satisfaction of the ownership of and the destruction, loss or
theft of any Security and (b) such security or indemnity as may be reasonably
required by them to save each of them and any agent of either of them harmless,
then, in the absence of notice to the Company or the Trustee that such Security
is held by a Person purporting to be the owner of such Security, the Company
shall execute and the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security, a new Security of the same series and
Tranche, and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

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

          Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
reasonable expenses (including the fees and expenses of the Trustee) 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 other than
the Holder of such new Security, and any such new Security shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Securities of such series duly issued hereunder.

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

SECTION 307.  Payment of Interest; Interest Rights Preserved.

          Unless otherwise specified as contemplated by Section 301 with respect
to the Securities of any series, or any Tranche thereof, 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.

          Subject to Section 312, 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 related Regular Record Date by virtue of

<PAGE>
                                      -23-

having been such Holder, and such Defaulted Interest may be paid by the Company,
at its election in each case, as provided in clause (a) or (b) below:

          (a) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a date (herein called 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 on or 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 promptly cause notice of the proposed payment of such Defaulted
     Interest and the Special Record Date therefor to be mailed, first-class
     postage prepaid, to each Holder of Securities of such series at the address
     of such Holder as it appears in the Security Register, not less than 10
     days prior to such Special Record Date. Notice of the proposed payment of
     such Defaulted Interest and the Special Record Date therefor having been so
     mailed, such Defaulted Interest shall be paid to the Persons in whose names
     the Securities of such series (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date.

          (b) The Company may make payment of any Defaulted Interest on the
     Securities of any series in any other lawful manner not inconsistent with
     the requirements of any securities exchange on which such Securities may be
     listed, and upon such notice as may be required by such exchange, if, after
     notice given by the Company to the Trustee of the proposed payment pursuant
     to this clause, such manner of payment shall be deemed practicable by the
     Trustee.

          Subject to the foregoing provisions of this Section and Section 305,
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 308.  Persons Deemed Owners.

          Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the absolute owner of
such Security for the purpose of receiving payment of principal of and premium,
if any, and (subject to Sections 305 and 307) interest, if any, on such Security
and for all other purposes whatsoever, whether or not such Security be overdue,

<PAGE>
                                      -24-

and neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

SECTION 309.  Cancellation by Security Registrar.

          All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Security
Registrar, be delivered to the Security Registrar and, if not theretofore
canceled, shall be promptly canceled by the Security Registrar. The Company may
at any time deliver to the Security Registrar for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever or which the Company shall not have issued and
sold, and all Securities so delivered shall be promptly canceled by the Security
Registrar. 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 Security
Registrar shall be disposed of in accordance with the customary practices of the
Security Registrar at the time in effect, and the Security Registrar shall not
be required to destroy any such certificates. The Security Registrar shall
promptly deliver a certificate of disposition to the Trustee and the Company
unless, by a Company Order, similarly delivered, the Company shall direct that
canceled Securities be returned to it. The Security Registrar shall promptly
deliver evidence of any cancellation of a Security in accordance with this
Section 309 to the Trustee and the Company.

SECTION 310.  Computation of Interest.

          Except as otherwise specified as contemplated by Section 301 for
Securities of any series, or any Tranche thereof, interest on the Securities of
each series shall be computed on the basis of a 360-day year consisting of
twelve 30-day months and for any period shorter than a full month, on the basis
of the actual number of days elapsed in such period.

SECTION 311.  Payment to Be in Proper Currency.

          In the case of the Securities of any series, or any Tranche thereof,
denominated in any currency other than Dollars or in a composite currency (the
"Required Currency"), except as otherwise specified with respect to such
Securities as contemplated by Section 301, the obligation of the Company to make
any payment of the principal thereof, or the premium or interest thereon, shall
not be discharged or satisfied by any tender by the Company, or recovery by the
Trustee, in any currency other than the Required Currency, except to the extent
that such tender or recovery shall result in the Trustee timely holding the full
amount of the Required Currency then due and payable. If any such tender or
recovery is in a currency other than the Required Currency, the Trustee may take
such actions as it considers appropriate to exchange such currency for the
Required Currency. The costs and risks of any such exchange, including without
limitation the risks of delay and exchange rate fluctuation, shall be borne by
the Company, the Company shall remain fully liable for any shortfall or
delinquency in the full amount of Required Currency then due and payable, and in
no circumstances shall the Trustee be liable therefor except in the case of its
negligence or willful misconduct.

<PAGE>
                                      -25-

SECTION 312.  Extension of Interest Payment.

          The Company shall have the right at any time, so long as the Company
is not in default in the payment of interest on the Securities of any series
hereunder, to extend interest payment periods on all Securities of one or more
series, if so specified as contemplated by Section 301 with respect to such
Securities and upon such terms as may be specified as contemplated by Section
301 with respect to such Securities.

                                  ARTICLE FOUR

                            Redemption of Securities

SECTION 401.  Applicability of Article.

          Securities of any series, or any Tranche thereof, which are redeemable
before their Stated Maturity shall be redeemable in accordance with their terms
and (except as otherwise specified as contemplated by Section 301 for Securities
of such series or Tranche) in accordance with this Article.

SECTION 402.  Election to Redeem; Notice to Trustee.

          The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution or an Officer's Certificate. The Company shall,
at least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date and of the principal amount of such Securities
to be redeemed. In the case of any redemption of Securities (a) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture or (b) pursuant to an election of the
Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officer's Certificate
evidencing compliance with such restriction or condition.

SECTION 403.  Selection of Securities to Be Redeemed.

          If less than all the Securities of any series, or any Tranche thereof,
are to be redeemed, the particular Securities to be redeemed shall be selected
by the Trustee from the Outstanding Securities of such series or Tranche not
previously called for redemption, by such method as shall be provided for any
particular series, or, in the absence of any such provision, by such method as
the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to the minimum authorized
denomination for Securities of such series or Tranche or any integral multiple
thereof) of the principal amount of Securities of such series or Tranche of a
denomination larger than the minimum authorized denomination for Securities of
such series or Tranche; provided, however, that if, as indicated in an Officer's
Certificate, the Company shall have offered to purchase all or any principal
amount of the Securities then Outstanding of any series, or any Tranche thereof,
and less than all of such Securities as to which such offer was made shall have
been tendered to the Company for such purchase, the Trustee, if so directed by
Company Order, shall select for redemption all or any principal amount of such
Securities which have not been so tendered.

<PAGE>
                                      -26-

          The Trustee shall promptly notify the Company and the Security
Registrar in writing of the Securities selected for redemption and, in the case
of any Securities selected to be redeemed in part, 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 404.  Notice of Redemption.

          Except as otherwise specified as contemplated by Section 301 for
Securities of any series, notice of redemption shall be given in the manner
provided in Section 106 to the Holders of the Securities to be redeemed not less
than 30 nor more than 60 days prior to the Redemption Date.

          Except as otherwise specified as contemplated by Section 301 for
Securities of any series, all notices of redemption shall state:

          (a) the Redemption Date,

          (b) the Redemption Price (if known),

          (c) if less than all the Securities of any series or Tranche are to be
     redeemed, the identification of the particular Securities to be redeemed
     and the portion of the principal amount of any Security to be redeemed in
     part,

          (d) that on the Redemption Date the Redemption Price, together with
     accrued interest, if any, to the Redemption Date, will become due and
     payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,

          (e) the place or places where such Securities are to be surrendered
     for payment of the Redemption Price and accrued interest, if any, unless it
     shall have been specified as contemplated by Section 301 with respect to
     such Securities that such surrender shall not be required,

          (f) that the redemption is for a sinking or other fund, if such is the
     case,

          (g) the CUSIP or ISIN numbers, if any, assigned to such Securities;
     provided, however, that such notice may state that no representation is
     made as to the correctness of CUSIP or ISIN numbers, in which case none of
     the Company, the Trustee or any agent of the Company or the Trustee shall
     have any liability in respect of the use of any CUSIP or ISIN number or
     numbers on such notices, and the redemption of such Securities shall not be
     affected by any defect in or omission of such numbers, and

          (h) such other matters as the Company shall deem desirable or
     appropriate.

<PAGE>
                                      -27-

          Unless otherwise specified with respect to any Securities in
accordance with Section 301, with respect to any notice of redemption of
Securities at the election of the Company, unless, upon the giving of such
notice, such Securities shall be deemed to have been paid in accordance with
Section 701, such notice may state that such redemption shall be conditional
upon the receipt by the Paying Agent or Agents for such Securities, on or prior
to the date fixed for such redemption, of money sufficient to pay the principal
of and premium, if any, and interest, if any, on such Securities and that if
such money shall not have been so received such notice shall be of no force or
effect and the Company shall not be required to redeem such Securities. In the
event that such notice of redemption contains such a condition and such money is
not so received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Paying Agent or Agents for the Securities
otherwise to have been redeemed shall promptly return to the Holders thereof any
of such Securities which had been surrendered for payment upon such redemption.

          Notice of redemption of Securities to be redeemed at the election of
the Company, and any notice of non-satisfaction of a condition for redemption as
aforesaid, shall be given by the Company or, at the Company's request, by the
Security Registrar in the name and at the expense of the Company. Notice of
mandatory redemption of Securities shall be given by the Security Registrar in
the name and at the expense of the Company.

SECTION 405.  Securities Payable on Redemption Date.

          Notice of redemption having been given as aforesaid, and the
conditions, if any, set forth in such notice having been satisfied, the
Securities or portions thereof 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, in the case of an unconditional notice of redemption,
the Company shall default in the payment of the Redemption Price and accrued
interest, if any) such Securities or portions thereof, if interest-bearing,
shall cease to bear interest. Upon surrender of any such Security for redemption
in accordance with such notice, such Security or portion thereof shall be paid
by the Company at the Redemption Price, together with accrued interest, if any,
to the Redemption Date; provided, however, that no such surrender shall be a
condition to such payment if so specified as contemplated by Section 301 with
respect to such Security; and provided, further, that except as otherwise
specified as contemplated by Section 301 with respect to such Security, any
installment of interest on any Security the Stated Maturity of which installment
is on or prior to the Redemption Date shall be payable to the Holder of such
Security, or one or more Predecessor Securities, registered as such at the close
of business on the related Regular Record Date according to the terms of such
Security and subject to the provisions of Section 307.

SECTION 406.  Securities Redeemed in Part.

          Upon the surrender of any Security which is to be redeemed only in
part 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), the Company shall execute, and the

<PAGE>
                                      -28-

Trustee shall authenticate and deliver to the Holder of such Security, without
service charge, a new Security or Securities of the same series and Tranche, of
any authorized denomination requested by such Holder and of like tenor and in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so surrendered.

                                  ARTICLE FIVE

                                  Sinking Funds

SECTION 501.  Applicability of Article.

          The provisions of this Article shall be applicable to any sinking fund
for the retirement of the Securities of any series, or any Tranche thereof,
except as otherwise specified as contemplated by Section 301 for Securities of
such series or Tranche.

          The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series, or any Tranche thereof, 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, or any Tranche
thereof, is herein referred to as an "optional sinking fund payment". If
provided for by the terms of Securities of any series, or any Tranche thereof,
the cash amount of any sinking fund payment may be subject to reduction as
provided in Section 502. Each sinking fund payment shall be applied to the
redemption of Securities of the series or Tranche in respect of which it was
made as provided for by the terms of such Securities.

SECTION 502.  Satisfaction of Sinking Fund Payments with Securities.

          The Company (a) may deliver to the Trustee Outstanding Securities
(other than any previously called for redemption) of a series or Tranche in
respect of which a mandatory sinking fund payment is to be made and (b) may
apply as a credit Securities of such series or Tranche which have been redeemed
either at the election of the Company pursuant to the terms of such Securities
or through the application of permitted optional sinking fund payments pursuant
to the terms of such Securities, in each case in satisfaction of all or any part
of such mandatory sinking fund payment with respect to the Securities of such
series; provided, however, that no Securities shall be applied in satisfaction
of a mandatory sinking fund payment if such Securities shall have been
previously so applied. Securities so applied shall be received and credited for
such purpose by the Trustee at the Redemption Price specified in such Securities
for redemption through operation of the sinking fund and the amount of such
mandatory sinking fund payment shall be reduced accordingly.

SECTION 503.  Redemption of Securities for Sinking Fund.

          Not less than 45 days prior to each sinking fund payment date for the
Securities of any series, or any Tranche thereof, the Company shall deliver to
the Trustee an Officer's Certificate specifying:

          (a) the amount of the next succeeding mandatory sinking fund payment
     for such series or Tranche;

<PAGE>
                                      -29-

          (b) the amount, if any, of the optional sinking fund payment to be
     made together with such mandatory sinking fund payment;

          (c) the aggregate sinking fund payment;

          (d) the portion, if any, of such aggregate sinking fund payment which
     is to be satisfied by the payment of cash; and

          (e) the portion, if any, of such aggregate sinking fund payment which
     is to be satisfied by delivering and crediting Securities of such series or
     Tranche pursuant to Section 502 and stating the basis for such credit and
     that such Securities have not previously been so credited, and the Company
     shall also deliver to the Trustee any Securities to be so delivered.

          If the Company shall have not delivered such Officer's Certificate
and, to the extent applicable, all such Securities, the next succeeding sinking
fund payment for such series or Tranche shall be made entirely in cash in the
amount of the mandatory sinking fund payment. Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
403 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 404. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 405 and 406.

                                  ARTICLE SIX

                                   Covenants

SECTION 601.  Payment of Principal, Premium and Interest.

          The Company shall pay the principal of and premium, if any, and
interest, if any, on the Securities of each series in accordance with the terms
of such Securities and this Indenture.

SECTION 602.  Maintenance of Office or Agency.

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

<PAGE>
                                      -30-

          The Company may also from time to time designate one or more other
offices or agencies with respect to the Securities of one or more series, or any
Tranche thereof, for any or all of the foregoing purposes and may from time to
time rescind such designations; provided, however, that, unless otherwise
specified as contemplated by Section 301 with respect to the Securities of such
series or Tranche, no such designation or rescission shall in any manner relieve
the Company of its obligation to maintain an office or agency for such purposes
in each Place of Payment for such Securities in accordance with the requirements
set forth above. The Company shall give prompt written notice to the Trustee,
and prompt notice to the Holders in the manner specified in Section 106, of any
such designation or rescission and of any change in the location of any such
other office or agency.

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

SECTION 603.  Money for Securities Payments to Be Held in Trust.

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

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

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

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

          (b) give the Trustee notice of any failure by the Company (or any
     other obligor upon such Securities) to make any payment of principal of or
     premium, if any, or interest, if any, on such Securities; and

<PAGE>
                                      -31-

          (c) at any time during the continuance of any such failure, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent and furnish to the Trustee such
     information as it possesses regarding the names and addresses of the
     Persons entitled to such sums.

          The Company may at any time pay, or by Company Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the Company or such
Paying Agent, such sums to be held by the Trustee upon the same trusts as those
upon which such sums were held by the Company or such Paying Agent and, if so
stated in a Company Order delivered to the Trustee, in accordance with the
provisions of Article Seven; 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, if any, on any Security 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, upon such payment or
discharge, the Holder of such Security shall, as an unsecured general creditor
and not as a Holder of an Outstanding Security, look only to the Company for
payment of the amount so due and payable and remaining unpaid, and all liability
of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make
any such payment to the Company, may at the expense of the Company cause to be
mailed, on one occasion only, notice to such Holder that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such mailing, any unclaimed balance of such money then
remaining will be paid to the Company.

SECTION 604.  Corporate Existence.

          Subject to the rights of the Company under Article Eleven, the Company
shall do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence.

SECTION 605.  Maintenance of Properties.

          The Company shall cause (or, with respect to property owned in common
with others, make reasonable effort to cause) all its properties used or useful
in the conduct of its business to be maintained and kept in good condition,
repair and working order and shall cause (or, with respect to property owned in
common with others, make reasonable effort to cause) to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as,
in the judgment of the Company, may be necessary so that the business carried on
in connection therewith may be properly conducted; provided, however, that
nothing in this Section shall prevent the Company from discontinuing, or causing
the discontinuance of, the operation and maintenance of any of its properties if
such discontinuance is, in the judgment of the Company, desirable in the conduct
of its business.

                                      -32-

SECTION 606.  Annual Officer's Certificate as to Compliance.

          Not later than June 1 in each year, commencing June 1, 2002, the
Company shall deliver to the Trustee an Officer's Certificate which need not
comply with Section 102, executed by the principal executive officer, the
principal financial officer or the principal accounting officer of the Company,
as to such officer's knowledge of the Company's compliance with all conditions
and covenants under this Indenture, such compliance to be determined without
regard to any period of grace or requirement of notice under this Indenture, and
making any other statements as may be required by the provisions of Section
314(a)(4) of the Trust Indenture Act.

SECTION 607.  Waiver of Certain Covenants.

          The Company may omit in any particular instance to comply with any
term, provision or condition set forth in (a) Section 602 or any additional
covenant or restriction specified with respect to the Securities of any series,
or any Tranche thereof, as contemplated by Section 301, if before the time for
such compliance the Holders of a majority in aggregate principal amount of the
Outstanding Securities of all series and Tranches with respect to which
compliance with Section 602 or such additional covenant or restriction is to be
omitted, considered as one class, shall, by Act of such Holders, either waive
such compliance in such instance or generally waive compliance with such term,
provision or condition and (b) Section 604, 605 or Article Eleven if before the
time for such compliance the Holders of a majority in principal amount of
Securities Outstanding under this Indenture shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such term, provision or condition; but, in the case of (a) or (b), 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.

SECTION 608.  Limitation on Liens.

          (a) Except as otherwise specified as contemplated by Section 301 for
     Securities of any series, so long as any Securities of any series are
     Outstanding, the Company will not pledge, mortgage, hypothecate or grant a
     security interest in, or permit any mortgage, pledge, security interest or
     other lien upon, any capital stock of any Subsidiary now or hereafter owned
     by the Company, to secure any Indebtedness (hereinafter defined) without
     concurrently making effective provision whereby the Outstanding Securities
     shall (so long as such other Indebtedness shall be so secured) be equally
     and ratably secured with any and all such other Indebtedness and any other
     indebtedness similarly entitled to be equally and ratably secured;
     provided, however, that this restriction shall not apply to nor prevent the
     creation or existence of:

               (1) any mortgage, pledge, security interest, lien or encumbrance
          upon any such capital stock created at the time of the acquisition of
          such capital stock by the Company or within 270 days after such time
          to secure all or a portion of the purchase price for such capital
          stock;

<PAGE>
                                      -33-

               (2) any mortgage, pledge, security interest, lien or encumbrance
          upon any such capital stock existing thereon at the time of the
          acquisition thereof by the Company (whether or not the obligations
          secured thereby are assumed by the Company);

               (3) any extension, renewal or refunding of any mortgage, pledge,
          security interest, lien or encumbrance permitted by Subsection (1) or
          (2) above on capital stock of any Subsidiary theretofore subject
          thereto (or substantially the same capital stock) or any portion
          thereof; or

               (4) any judgment, levy, execution, attachment or other similar
          lien arising in connection with court proceedings, provided that
          either

               (ii) the execution or enforcement of each such lien is
                    effectively stayed within 30 days after entry of the
                    corresponding judgment (or the corresponding judgment has
                    been discharged within such 30 day period) and the claims
                    secured thereby are being contested in good faith by
                    appropriate proceedings timely commenced and diligently
                    prosecuted;

              (iii) the payment of each such lien is covered in full by
                    insurance and the insurance company has not denied or
                    contested coverage thereof; or

               (iv) so long as each such lien is adequately bonded, any
                    appropriate legal proceedings that may have been duly
                    initiated for the review of the corresponding judgment,
                    decree or order shall not have been fully terminated or the
                    period within which such proceedings may be initiated shall
                    not have expired.

          For purposes of this Section 608, "Indebtedness" means all
indebtedness, whether or not represented by bonds, debentures, notes or other
securities, created or assumed by the Company for the repayment of money
borrowed. All indebtedness for money borrowed secured by a lien upon property
owned by the Company and upon which indebtedness for money borrowed the Company
customarily pays interest, although the Company has not assumed or become liable
for the payment of such indebtedness for money borrowed, shall for purposes of
this Section 608 be deemed to be Indebtedness of the Company. All indebtedness
of others for money borrowed which is guaranteed as to payment of principal by
the Company or in effect guaranteed by the Company through a contingent
agreement to purchase such indebtedness for money borrowed shall for purposes of
this Section 608 be deemed to be Indebtedness of the Company, but no other
contingent obligation of the Company in respect of indebtedness for money
borrowed or other obligations incurred by others shall for purposes of this
Section 608 be deemed to be Indebtedness of the Company.

          In case the Company shall propose to pledge, mortgage, hypothecate or
grant a security interest in any capital stock of any Subsidiary owned by the
Company to secure any Indebtedness, other than as permitted by Subsections
(a)(1) to (a)(3), inclusive, of this Section, the Company will prior thereto

<PAGE>
                                      -34-

give written notice thereof to the Trustee, and the Company will prior to or
simultaneously with such pledge, mortgage, hypothecation or grant of security
interest, by supplemental indenture executed to the Trustee (or to the extent
legally necessary to another trustee or an additional or separate trustee), in
form satisfactory to the Trustee, effectively secure (for so long as such other
Indebtedness shall be so secured) all the Securities equally and ratably with
such Indebtedness and with any other indebtedness for money borrowed similarly
entitled to be equally and ratably secured.

          (b) Except as otherwise specified as contemplated by Section 301 for
     Securities of any series, the provisions of Subsection (a) of this Section
     608 shall not apply in the event that the Company shall pledge, mortgage,
     hypothecate or grant a security interest in or other lien upon any capital
     stock of any Subsidiary now or hereafter owned by the Company to secure any
     Indebtedness which would otherwise be subject to the foregoing restriction
     up to an aggregate amount which, together with all other Indebtedness
     (other than mortgages, pledges, security interests, liens or encumbrances
     permitted by Subsection (a) of this Section 608) which would otherwise be
     subject to the foregoing restriction, does not at the time exceed 5% of
     Consolidated Capitalization.

          For purposes of this Section 608:

               (1) The term "Consolidated Capitalization" means the sum obtained
          by adding (i) Consolidated Shareholders' Equity, (ii) Consolidated
          Indebtedness for money borrowed (exclusive of any thereof which is due
          and payable within one year of the date such sum is determined) and,
          without duplication, (iii) any preference or preferred stock of the
          Company or any Consolidated Subsidiary which is subject to mandatory
          redemption or sinking fund provisions.

               (2) The term "Consolidated Shareholders' Equity" means the total
          Assets of the Company and its Consolidated Subsidiaries less all
          liabilities of the Company and its Consolidated Subsidiaries. As used
          in this definition, "liabilities" means all obligations which would,
          in accordance with generally accepted accounting principles, be
          classified on a balance sheet as liabilities, including without
          limitation, (i) indebtedness secured by property of the Company or any
          of its Consolidated Subsidiaries whether or not the Company or such
          Consolidated Subsidiary is liable for the payment thereof unless, in
          the case that the Company or such Consolidated Subsidiary is not so
          liable, such property has not been included among the Assets of the
          Company or such Consolidated Subsidiary on such balance sheet, (ii)
          deferred liabilities, (iii) indebtedness of the Company or any of its
          Consolidated Subsidiaries that is expressly subordinated in right and
          priority of payment to other liabilities of the Company or such
          Consolidated Subsidiary. As used in this definition, "liabilities"
          includes preference or preferred stock of the Company or any
          Consolidated Subsidiary only to the extent of any such preference or
          preferred stock that is subject to mandatory redemption or sinking
          fund provisions.

               (3) The term "Consolidated Subsidiary" means at any date any
          Subsidiary the financial statements of which under generally accepted

<PAGE>
                                      -35-

          accounting principles would be consolidated with those of the Company
          in its consolidated financial statements as of such date.

               (4) The "Assets" of any Person means the whole or any part of its
          business, property, assets, cash and receivables.

               (5) The term "Consolidated Indebtedness" means total indebtedness
          as shown on the consolidated balance sheet of the Company and its
          Consolidated Subsidiaries.

                           Satisfaction and Discharge

SECTION 701.  Satisfaction and Discharge of Securities.

          Any Security or Securities, or any portion of the principal amount
thereof, shall be deemed to have been paid for all purposes of this Indenture,
and the entire indebtedness of the Company in respect thereof shall be deemed to
have been satisfied and discharged, if there shall have been irrevocably
deposited with the Trustee or any Paying Agent (other than the Company), in
trust:

          (a) money in an amount which shall be sufficient, or

          (b) in the case of a deposit made prior to the Maturity of such
     Securities or portions thereof, Eligible Obligations, which shall not
     contain provisions permitting the redemption or other prepayment thereof at
     the option of the issuer thereof, the principal of and the interest on
     which when due, without any regard to reinvestment thereof, will provide
     moneys which, together with the money, if any, deposited with or held by
     the Trustee or such Paying Agent, shall be sufficient, or

          (c) a combination of (a) or (b) which shall be sufficient,
to pay when due the principal of and premium, if any, and interest, if any, due
and to become due on such Securities or portions thereof on or prior to
Maturity; provided, however, that in the case of the provision for payment or
redemption of less than all the Securities of any series or Tranche, such
Securities or portions thereof shall have been selected by the Trustee as
provided herein and, in the case of a redemption, the notice requisite to the
validity of such redemption shall have been given or irrevocable authority shall
have been given by the Company to the Trustee to give such notice, under
arrangements satisfactory to the Trustee; and provided, further, that the
Company shall have delivered to the Trustee and such Paying Agent:

               (x) if such deposit shall have been made prior to the Maturity of
          such Securities, a Company Order stating that the money and Eligible
          Obligations deposited in accordance with this Section shall be held in
          trust, as provided in Section 703; and

<PAGE>
                                      -36-

               (y) if Eligible Obligations shall have been deposited, an Opinion
          of Counsel that the obligations so deposited constitute Eligible
          Obligations and do not contain provisions permitting the redemption or
          other prepayment at the option of the issuer thereof, and an opinion
          of an independent public accountant of nationally recognized standing,
          selected by the Company, to the effect that the requirements set forth
          in clause (b) above have been satisfied; and

               (z) if such deposit shall have been made prior to the Maturity of
          such Securities, an Officer's Certificate stating the Company's
          intention that, upon delivery of such Officer's Certificate, its
          indebtedness in respect of such Securities or portions thereof will
          have been satisfied and discharged as contemplated in this Section.

          Upon the deposit of money or Eligible Obligations, or both, in
accordance with this Section, together with the documents required by clauses
(x), (y) and (z) above, the Trustee shall, upon receipt of a Company Request,
acknowledge in writing that the Security or Securities or portions thereof with
respect to which such deposit was made are deemed to have been paid for all
purposes of this Indenture and that the entire indebtedness of the Company in
respect thereof has been satisfied and discharged as contemplated in this
Section. In the event that all of the conditions set forth in the preceding
paragraph shall have been satisfied in respect of any Securities or portions
thereof except that, for any reason, the Officer's Certificate specified in
clause (z) shall not have been delivered, such Securities or portions thereof
shall nevertheless be deemed to have been paid for all purposes of this
Indenture, and the Holders of such Securities or portions thereof shall
nevertheless be no longer entitled to the benefits of this Indenture or of any
of the covenants of the Company under Article Six (except the covenants
contained in Sections 602 and 603) or any other covenants made in respect of
such Securities or portions thereof as contemplated by Section 301, but the
indebtedness of the Company in respect of such Securities or portions thereof
shall not be deemed to have been satisfied and discharged prior to Maturity for
any other purpose, and the Holders of such Securities or portions thereof shall
continue to be entitled to look to the Company for payment of the indebtedness
represented thereby; and, upon Company Request, the Trustee shall acknowledge in
writing that such Securities or portions thereof are deemed to have been paid
for all purposes of this Indenture.

          If payment at Stated Maturity of less than all of the Securities of
any series, or any Tranche thereof, is to be provided for in the manner and with
the effect provided in this Section, the Security Registrar shall select such
Securities, or portions of principal amount thereof, in the manner specified by
Section 403 for selection for redemption of less than all the Securities of a
series or Tranche.

          In the event that Securities which shall be deemed to have been paid
for purposes of this Indenture, and, if such is the case, in respect of which
the Company's indebtedness shall have been satisfied and discharged, all as
provided in this Section do not mature and are not to be redeemed within the 60
day period commencing with the date of the deposit of moneys or Eligible
Obligations, as aforesaid, the Company shall, as promptly as practicable, give a
notice, in the same manner as a notice of redemption with respect to such
Securities, to the Holders of such Securities to the effect that such deposit
has been made and the effect thereof.

<PAGE>
                                      -37-

          Notwithstanding that any Securities shall be deemed to have been paid
for purposes of this Indenture, as aforesaid, the obligations of the Company and
the Trustee in respect of such Securities under Sections 304, 305, 306, 404, 503
(as to notice of redemption), 602, 603, 907 and 915 and this Article Seven shall
survive.

          The Company shall pay, and shall indemnify the Trustee or any Paying
Agent with which Eligible Obligations shall have been deposited as provided in
this Section against, any tax, fee or other charge imposed on or assessed
against such Eligible Obligations or the principal or interest received in
respect of such Eligible Obligations, including, but not limited to, any such
tax payable by any entity deemed, for tax purposes, to have been created as a
result of such deposit.

          Anything herein to the contrary notwithstanding, (a) if, at any time
after a Security would be deemed to have been paid for purposes of this
Indenture, and, if such is the case, the Company's indebtedness in respect
thereof would be deemed to have been satisfied or discharged, pursuant to this
Section (without regard to the provisions of this paragraph), the Trustee or any
Paying Agent, as the case may be, shall be required to return the money or
Eligible Obligations, or combination thereof, deposited with it as aforesaid to
the Company or its representative under any applicable Federal or State
bankruptcy, insolvency or other similar law, such Security shall thereupon be
deemed retroactively not to have been paid and any satisfaction and discharge of
the Company's indebtedness in respect thereof shall retroactively be deemed not
to have been effected, and such Security shall be deemed to remain Outstanding
and (b) any satisfaction and discharge of the Company's indebtedness in respect
of any Security shall be subject to the provisions of the last paragraph of
Section 603.

SECTION 702.  Satisfaction and Discharge of Indenture.

          This Indenture shall upon Company Request cease to be of further
effect (except as hereinafter expressly provided), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

          (a)  no Securities remain Outstanding hereunder; and

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

provided, however, that if, in accordance with the last paragraph of Section
701, any Security, previously deemed to have been paid for purposes of this
Indenture, shall be deemed retroactively not to have been so paid, this
Indenture shall thereupon be deemed retroactively not to have been satisfied and
discharged, as aforesaid, and to remain in full force and effect, and the
Company shall execute and deliver such instruments as the Trustee shall
reasonably request to evidence and acknowledge the same.

          Notwithstanding the satisfaction and discharge of this Indenture as
aforesaid, the obligations of the Company and the Trustee under Sections 304,
305, 306, 404, 503 (as to notice of redemption), 602, 603, 907 and 915 and this
Article Seven shall survive.

<PAGE>
                                      -38-

          Upon satisfaction and discharge of this Indenture as provided in this
Section, the Trustee shall assign, transfer and turn over to the Company,
subject to the lien provided by Section 907, any and all money, securities and
other property then held by the Trustee for the benefit of the Holders of the
Securities other than money and Eligible Obligations held by the Trustee
pursuant to Section 703.

SECTION 703.  Application of Trust Money.

          Neither the Eligible Obligations nor the money deposited pursuant to
Section 701, nor the principal or interest payments on any such Eligible
Obligations, shall be withdrawn or used for any purpose other than, and shall be
held in trust for, the payment of the principal of and premium, if any, and
interest, if any, on the Securities or portions of principal amount thereof in
respect of which such deposit was made, all subject, however, to the provisions
of Section 603; provided, however, that, so long as there shall not have
occurred and be continuing an Event of Default, any cash received from such
principal or interest payments on such Eligible Obligations, if not then needed
for such purpose, shall, to the extent practicable and upon Company Request, be
invested in Eligible Obligations of the type described in clause (b) in the
first paragraph of Section 701 maturing at such times and in such amounts as
shall be sufficient, together with any other moneys and the principal of and
interest on any other Eligible Obligations then held by the Trustee, to pay when
due the principal of and premium, if any, and interest, if any, due and to
become due on such Securities or portions thereof on and prior to the Maturity
thereof, and interest earned from such reinvestment shall be paid over to the
Company as received, free and clear of any trust, lien or pledge under this
Indenture except the lien provided by Section 907; and provided, further, that,
so long as there shall not have occurred and be continuing an Event of Default,
any moneys held in accordance with this Section on the Maturity of all such
Securities in excess of the amount required to pay the principal of and premium,
if any, and interest, if any, then due on such Securities shall be paid over to
the Company free and clear of any trust, lien or pledge under this Indenture
except the lien provided by Section 907; and provided, further, that if an Event
of Default shall have occurred and be continuing, moneys to be paid over to the
Company pursuant to this Section shall be held until such Event of Default shall
have been waived or cured.

                           Events of Default; Remedies

SECTION 801.  Events of Default.

          "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events:

          (a)  failure to pay interest, if any, on any Security of such series
     within 30 days after the same becomes due and payable; provided, however,
     that a valid extension of the interest payment period by the Company as
     contemplated in Section 312 of this Indenture shall not constitute a
     failure to pay interest for this purpose; or

<PAGE>
                                      -39-

          (b)  failure to pay the principal of or premium, if any, on any
     Security of such series at its Maturity; or

          (c)  failure to perform or breach of any covenant or warranty of the
     Company in this Indenture (other than a covenant or warranty a default in
     the performance of which or breach of which is elsewhere in this Section
     specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of one or more series of Securities other
     than such series) for a period of 90 days after there has been given, by
     registered or certified mail, to the Company by the Trustee, or to the
     Company and the Trustee by the Holders of at least 33% in principal amount
     of the Outstanding Securities of such series, a written notice specifying
     such default or breach and requiring it to be remedied and stating that
     such notice is a "Notice of Default" hereunder, unless the Trustee, or the
     Trustee and the Holders of a principal amount of Securities of such series
     not less than the principal amount of Securities the Holders of which gave
     such notice, as the case may be, shall agree in writing to an extension of
     such period prior to its expiration; provided, however, that the Trustee,
     or the Trustee and the Holders of such principal amount of Securities of
     such series, as the case may be, shall be deemed to have agreed to an
     extension of such period if corrective action is initiated by the Company
     within such period and is being diligently pursued; or

          (d)  the entry by a court having jurisdiction in the premises of (1) a
     decree or order for relief in respect of the Company in an involuntary case
     or proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or (2) a decree or order adjudging the
     Company a bankrupt or insolvent, or approving as properly filed a petition
     by one or more Persons other than the Company seeking reorganization,
     arrangement, adjustment or composition of or in respect of the Company
     under any applicable Federal or State law, or appointing a custodian,
     receiver, liquidator, assignee, trustee, sequestrator or other similar
     official for the Company or for any substantial part of its property, or
     ordering the winding up or liquidation of its affairs, and any such decree
     or order for relief or any such other decree or order shall have remained
     unstayed and in effect for a period of 90 consecutive days; or

          (e)  the commencement by the Company of a voluntary case or proceeding
     under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Company in a case or
     proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or to the commencement of any
     bankruptcy or insolvency case or proceeding against it, or the filing by it
     of a petition or answer or consent seeking reorganization or relief under
     any applicable Federal or State law, or the consent by it to the filing of
     such petition or to the appointment of or taking possession by a custodian,
     receiver, liquidator, assignee, trustee, sequestrator or 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 creditors, or the admission by it in
     writing of its inability to pay its debts generally as they become due, or
     the authorization of such action by the Board of Directors; or

          (f)  any other Event of Default specified with respect to Securities
     of such series.

                                      -40-

SECTION 802.  Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default due to the default in payment of principal of,
or interest on, any series of Securities or due to the default in the
performance or breach of any other covenant or warranty of the Company
applicable to the Securities of such series but not applicable to all
Outstanding Securities shall have occurred and be continuing, either the Trustee
or the Holders of not less than 33% in principal amount of the Securities of
such series may then declare the principal amount (or, if any of the Securities
of such series are Discount Securities, such portion of the principal amount as
may be specified in the terms thereof as contemplated by Section 301) of all
Securities of such series and interest accrued thereon to be due and payable
immediately. If an Event of Default due to default in the performance of any
other of the covenants or agreements herein applicable to all Outstanding
Securities or an Event of Default specified in Section 801(d) or (e) shall have
occurred and be continuing, either the Trustee or the Holders of not less than
33% in principal amount of all Securities then Outstanding (considered as one
class), and not the Holders of the Securities of any one of such series, may
declare the principal of all Securities and interest accrued thereon to be due
and payable immediately. As a consequence of each such declaration (herein
referred to as a declaration of acceleration) with respect to Securities of any
series, the principal amount (or portion thereof in the case of Discount
Securities) of such Securities and interest accrued thereon shall become due and
payable immediately.

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

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

               (1) all overdue interest on all Securities of such series;

               (2) the principal of and premium, if any, on any Securities of
          such series which have become due otherwise than by such declaration
          of acceleration and interest thereon at the rate or rates prescribed
          therefor in such Securities;

               (3) to the extent that payment of such interest is lawful,
          interest upon overdue interest, if any, at the rate or rates
          prescribed therefor in such Securities;

               (4) all amounts due to the Trustee under Section 907;

and

          (b)  any other Event or Events of Default with respect to Securities
     of such series, other than the nonpayment of the principal of Securities of
     such series which shall have become due solely by such declaration of
     acceleration, shall have been cured or waived as provided in Section 813.

<PAGE>
                                      -41-

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

SECTION 803.  Collection of Indebtedness and Suits for Enforcement by Trustee.

          If an Event of Default described in clause (a) or (b) of Section 801
shall have occurred and be continuing, the Company shall, upon demand of the
Trustee, pay to it, for the benefit of the Holders of the Securities of the
series with respect to which such Event of Default shall have occurred, the
whole amount then due and payable on such Securities for principal and premium,
if any, and interest, if any, and, to the extent permitted by law, interest on
any overdue principal and interest, at the rate or rates prescribed therefor in
such Securities, and, in addition thereto, such further amount as shall be
sufficient to cover any amounts due to the Trustee under Section 907.

          If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon 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 shall
have occurred and be continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities 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 804.  Trustee May File Proofs of Claim.

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

          (a)  to file and prove a claim for the whole amount of principal,
     premium, if any, and interest, if any, owing and unpaid in respect of the
     Securities and to file such other papers or documents as may be necessary
     or advisable in order to have the claims of the Trustee (including any
     claim for amounts due to the Trustee under Section 907) and of the Holders
     allowed in such judicial proceeding, and

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

<PAGE>
                                      -42-

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amounts due it under Section 907.

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

SECTION 805.  Trustee May Enforce Claims Without Possession of Securities.

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

SECTION 806.  Application of Money Collected.

          Any money collected by the Trustee pursuant to this Article 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, if any, upon presentation of the Securities in respect of
which or for the benefit of which such money shall have been collected and the
notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

          FIRST: To the payment of all amounts due the Trustee under Section
907;

          SECOND: To the payment of the amounts then due and unpaid upon the
Securities for principal of and premium, if any, and interest, if any, 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, premium, if any, and interest,
if any, respectively; and

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

SECTION 807.  Limitation on Suits.

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

<PAGE>
                                      -43-

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

          (b)  the Holders of a majority in aggregate principal amount of the
     Outstanding Securities of all series in respect of which an Event of
     Default shall have occurred and be continuing, considered as one class,
     shall have made written request to the Trustee to institute proceedings in
     respect of such Event of Default in its own name as Trustee hereunder;

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

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

          (e)  no direction inconsistent with such written request shall have
     been given to the Trustee during such 60-day period by the Holders of a
     majority in aggregate principal amount of the Outstanding Securities of all
     series in respect of which an Event of Default shall have occurred and be
     continuing, considered as one class;

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

SECTION 808.  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
Sections 307 and 312) interest, if any, on such Security on the Stated Maturity
or Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

SECTION 809.  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 shall have been
discontinued or abandoned for any reason, or shall have been determined
adversely to the Trustee or to such Holder, then and in every such case, subject
to any determination in such proceeding, the Company, and Trustee and such
Holder shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and such Holder
shall continue as though no such proceeding had been instituted.

<PAGE>
                                      -44-

SECTION 810.  Rights and Remedies Cumulative.

          Except as otherwise provided in the last paragraph of Section 306, 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 811.  Delay or Omission Not Waiver.

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

SECTION 812.  Control by Holders of Securities.

          If an Event of Default shall have occurred and be continuing in
respect of a series of Securities, the Holders of a majority in principal amount
of the Outstanding Securities of such 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, however, that if an Event of
Default shall have occurred and be continuing with respect to more than one
series of Securities, the Holders of a majority in aggregate principal amount of
the Outstanding Securities of all such series, considered as one class, shall
have the right to make such direction, and not the Holders of the Securities of
any one of such series; and provided, further, that such direction shall not be
in conflict with any rule of law or with this Indenture. The Trustee may take
any other action, deemed proper by the Trustee, which is not inconsistent with
any such direction. Before proceeding to exercise any right or power hereunder
at the direction of such Holders, the Trustee shall be entitled to receive from
such Holders reasonable security or indemnity against the costs, expenses and
liabilities which might be incurred by it in compliance with any such direction.

SECTION 813.  Waiver of Past Defaults.

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

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

          (b)  in respect of a covenant or provision hereof which under Section
     1202 cannot be modified or amended without the consent of the Holder of
     each Outstanding Security of such series affected.

<PAGE>
                                      -45-

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

SECTION 814.  Undertaking for Costs.

          The Company and the Trustee agree, and each Holder by his acceptance
thereof shall be deemed to have agreed, that any court may in its discretion
require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in aggregate
principal amount of the Outstanding Securities of all series in respect of which
such suit may be brought, considered as one class, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of or premium, if
any, or interest, if any, on any Security on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

SECTION 815.  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 NINE

                                   The Trustee

SECTION 901.  Certain Duties and Responsibilities.

          (a)  The Trustee shall have and be subject to all the duties and
     responsibilities specified with respect to an indenture trustee in the
     Trust Indenture Act and no implied covenants or obligations shall be read
     into this Indenture against the Trustee. For purposes of Sections 315(a)
     and 315(c) of the Trust Indenture Act, the term "default" is hereby defined
     as an Event of Default which has occurred and is continuing.

          (b)  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

<PAGE>
                                      -46-

     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

          (c)  Notwithstanding anything contained in this Indenture to the
     contrary, the duties and responsibilities of the Trustee under this
     Indenture shall be subject to the protections, exculpations and limitations
     on liability afforded to an indenture trustee under the provisions of the

     Company, personally or by agent or attorney;

     Event of Default, as the case may be, exists and constitutes a default or
     Event of Default under this Indenture or (2) written notice of such default

SECTION 904.  Not Responsible for Recitals or Issuance of Securities.

          The recitals contained herein and in the Securities (except the

the Company, and neither the Trustee nor any Authenticating Agent assumes

<PAGE>
                                      -48-

responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.

SECTION 905.  May Hold Securities.

          Each of 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 908 and 913, may otherwise deal with the Company with the same rights
it would have if it were not the Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.

SECTION 906.  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
expressly provided herein or otherwise agreed with, and for the sole benefit of,
the Company.

SECTION 907.  Compensation and Reimbursement.

          The Company shall

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

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

          (c)  indemnify the Trustee for, and hold it harmless from and against,
     any loss, liability or expense reasonably incurred by it arising out of or
     in connection with the acceptance or administration of the trust or trusts
     hereunder or the performance of its duties hereunder, including the
     reasonable costs and expenses of defending itself against any claim or
     liability in connection with the exercise or performance of any of its
     powers or duties hereunder, except to the extent any such loss, liability
     or expense may be attributable to its negligence, willful misconduct or bad
     faith.

          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 other than
property and funds held in trust under Section 703 (except as otherwise provided
in Section 703). "Trustee" for purposes of this Section shall include any
predecessor Trustee; provided, however, that the negligence, willful misconduct
or bad faith of any Trustee hereunder shall not affect the rights of any other
Trustee hereunder.

<PAGE>

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 801(d) or Section 801(e), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

          The provisions of this Section 907 shall survive the termination of
this Indenture.

SECTION 908.  Disqualification; Conflicting Interests.

the meaning of the Trust Indenture Act, it shall either eliminate such
conflicting interest or resign to the extent, in the manner and with the effect,
and subject to the conditions, provided in the Trust Indenture Act and this
Indenture. For purposes of Section 310(b)(1) of the Trust Indenture Act and to
the extent permitted thereby, the Trustee, in its capacity as trustee in respect
of the Securities of any series, shall not be deemed to have a conflicting
interest arising from its capacity as trustee in respect of the Securities of

Unsecured Debt Securities Series A), dated as of October 1, 1997, of the Company

SECTION 909.  Corporate Trustee Required; Eligibility.

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

          (a)  a corporation organized and doing business under the laws of the
     United States, any State or Territory thereof or the District of Columbia,
     authorized under such laws to exercise corporate trust powers, having a
     combined capital and surplus of at least $50,000,000 and subject to
     supervision or examination by Federal or State authority, or

          (b)  if and to the extent permitted by the Commission by rule,
     regulation or order upon application, a corporation or other Person
     organized and doing business under the laws of a foreign government,
     authorized under such laws to exercise corporate trust powers, having a

<PAGE>
                                      -50-

     combined capital and surplus of at least $50,000,000 or the Dollar
     equivalent of the applicable foreign currency and subject to supervision or
     examination by authority of such foreign government or a political
     subdivision thereof substantially equivalent to supervision or examination
     applicable to United States institutional trustees,

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

SECTION 910.  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 911.

          (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 911
     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 908 after
          written request therefor by the Company or by any Holder who has been
          a bona fide Holder for at least six months, or

               (2) the Trustee shall cease to be eligible under Section 909 and
          shall fail to resign after written request therefor by the Company or
          by any such Holder, or

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

then, in any such case, (x) the Company by a Board Resolution may remove the
Trustee with respect to all Securities or (y) subject to Section 814, any Holder
who has been a bona fide Holder for at least six months may, on behalf of

<PAGE>
                                      -51-

himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

          (e)  If the Trustee shall resign, be removed or become incapable of
     acting, or if a vacancy shall occur in the office of Trustee for any cause
     (other than as contemplated in clause (y) in Subsection (d) of this
     Section), with respect to the Securities of one or more series, the
     Company, by a Board Resolution, 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 911. If, within one year after such resignation, removal or
     incapability, or the occurrence of such vacancy, a successor Trustee with
     respect to the Securities of any series 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 911,
     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 911, any Holder who
     has been a bona fide Holder of a Security of such series for at least six
     months may, on behalf of itself and all others similarly situated, petition
     any court of competent jurisdiction for the appointment of a successor
     Trustee with respect to the Securities of such series.

          (f)  So long as no event which is, or after notice or lapse of time,
     or both, would become, an Event of Default shall have occurred and be
     continuing, and except with respect to a Trustee appointed by Act of the
     Holders of a majority in principal amount of the Outstanding Securities
     pursuant to Subsection (e) of this Section, if the Company shall have
     delivered to the Trustee (i) a Board Resolution appointing a successor
     Trustee, effective as of a date specified therein, and (ii) an instrument
     of acceptance of such appointment, effective as of such date, by such
     successor Trustee in accordance with Section 911, the Trustee shall be
     deemed to have resigned as contemplated in Subsection (b) of this Section,
     the successor Trustee shall be deemed to have been appointed by the Company
     pursuant to Subsection (e) of this Section and such appointment shall be
     deemed to have been accepted as contemplated in Section 911, all as of such
     date, and all other provisions of this Section and Section 911 shall be
     applicable to such resignation, appointment and acceptance except to the
     extent inconsistent with this Subsection (f).

          (g)  The Company (or, should the Company fail so to act promptly, the
     successor trustee at the expense of 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 by mailing written notice of such event by
     first-class mail, postage prepaid, to all Holders of Securities of such
     series as their names and addresses appear in the Security Register. Each
     notice 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 911.  Acceptance of Appointment by Successor.

          (a)  In case of the appointment hereunder of a successor Trustee with
     respect to the Securities of all series, 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 all sums owed to it,
     execute and deliver an instrument transferring to such successor Trustee
     all the rights, powers and trusts of the retiring Trustee and shall duly
     assign, transfer and deliver to such successor Trustee all property and
     money held by such retiring Trustee hereunder.

          (b)  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, upon payment of all sums owed to it, 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 instruments which fully vest in and confirm to such successor
     Trustee all such rights, powers and trusts referred to in Subsection (a) or
     (b) of this Section, as the case may be.

<PAGE>
                                      -53-

          (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 912.  Merger, Conversion, Consolidation or Succession to Business.

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

SECTION 913.  Preferential Collection of Claims Against Company.

          If the Trustee shall be or become a creditor of the Company or any
other obligor upon the Securities (other than by reason of a relationship
described in Section 311(b) of the Trust Indenture Act), the Trustee shall be
subject to any and all applicable provisions of the Trust Indenture Act
regarding the collection of claims against the Company or such other obligor.
For purposes of Section 311(b) of the Trust Indenture Act:

          (a)  the term "cash transaction" means any transaction in which full
     payment for goods or securities sold is made within seven days after
     delivery of the goods or securities in currency or in checks or other
     orders drawn upon banks or bankers and payable upon demand;

          (b)  the term "self-liquidating paper" means any draft, bill of
     exchange, acceptance or obligation which is made, drawn, negotiated or
     incurred by the Company for the purpose of financing the purchase,
     processing, manufacturing, shipment, storage or sale of goods, wares or
     merchandise and which is secured by documents evidencing title to,
     possession of, or a lien upon, the goods, wares or merchandise or the
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor
     relationship with the Company arising from the making, drawing, negotiating
     or incurring of the draft, bill of exchange, acceptance or obligation.

SECTION 914.  Co-trustees and Separate Trustees.

          At any time or times, for the purpose of meeting the legal
requirements of any applicable jurisdiction, the Company and the Trustee shall
have power to appoint, and, upon the written request of the Trustee or of the
Holders of at least 33% in principal amount of the Securities then Outstanding,
the Company shall for such purpose join with the Trustee in the execution and
delivery of all instruments and agreements necessary or proper to appoint, one
or more Persons approved by the Trustee either to act as co-trustee, jointly
with the Trustee, or to act as separate trustee, in either case with such powers
as may be provided in the instrument of appointment, and to vest in such Person

<PAGE>
                                      -54-

or Persons, in the capacity aforesaid, any property, title, right or power
deemed necessary or desirable, subject to the other provisions of this Section.
If the Company does not join in such appointment within 15 days after the
receipt by it of a request so to do, or if an Event of Default shall have
occurred and be continuing, the Trustee alone shall have power to make such
appointment.

          Should any written instrument or instruments from the Company be
required by any co-trustee or separate trustee so appointed to more fully
confirm to such co-trustee or separate trustee such property, title, right or
power, any and all such instruments shall, on request, be executed, acknowledged
and delivered by the Company.

          Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following conditions:

          (a)  the Securities shall be authenticated and delivered, and all
     rights, powers, duties and obligations hereunder in respect of the custody
     of securities, cash and other personal property held by, or required to be
     deposited or pledged with, the Trustee hereunder, shall be exercised
     solely, by the Trustee;

          (b)  the rights, powers, duties and obligations hereby conferred or
     imposed upon the Trustee in respect of any property covered by such
     appointment shall be conferred or imposed upon and exercised or performed
     either by the Trustee or by the Trustee and such co-trustee or separate
     trustee jointly, as shall be provided in the instrument appointing such
     co-trustee or separate trustee, except to the extent that under any law of
     any jurisdiction in which any particular act is to be performed, the
     Trustee shall be incompetent or unqualified to perform such act, in which
     event such rights, powers, duties and obligations shall be exercised and
     performed by such co-trustee or separate trustee;

          (c)  the Trustee at any time, by an instrument in writing executed by
     it, with the concurrence of the Company, may accept the resignation of or
     remove any co-trustee or separate trustee appointed under this Section,
     and, if an Event of Default shall have occurred and be continuing, the
     Trustee shall have power to accept the resignation of, or remove, any such
     co-trustee or separate trustee without the concurrence of the Company. Upon
     the written request of the Trustee, the Company shall join with the Trustee
     in the execution and delivery of all instruments and agreements necessary
     or proper to effectuate such resignation or removal. A successor to any
     co-trustee or separate trustee so resigned or removed may be appointed in
     the manner provided in this Section;

          (d)  no co-trustee or separate trustee hereunder shall be personally
     liable by reason of any act or omission of the Trustee, or any other such
     trustee hereunder; and

          (e)  any Act of Holders delivered to the Trustee shall be deemed to
     have been delivered to each such co-trustee and separate trustee.

SECTION 915.  Appointment of Authenticating Agent.

          The Trustee may appoint an Authenticating Agent or Agents with respect
to the Securities of one or more series, or Tranche thereof, which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such

<PAGE>
                                      -55-

series or Tranche issued upon original issuance and upon exchange, registration
of transfer or partial redemption thereof or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States, any State or territory thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, 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 may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company. Any successor Authenticating
Agent upon acceptance of its appointment hereunder shall become vested with all
the rights, powers and duties of its predecessor hereunder, with like effect as
if originally named as an Authenticating Agent. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.

          The 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, in accordance
with, and subject to the provisions of, Section 907.

          The provisions of Sections 308, 904 and 905 shall be applicable to
each Authenticating Agent.

<PAGE>
                                      -56-

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

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

                                               As Authenticating Agent

          If all of the Securities of a series may not be originally issued at
one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested by the Company in writing (which writing
need not comply with Section 102 and need not be accompanied by an Opinion of
Counsel), shall appoint, in accordance with this Section and in accordance with
such procedures as shall be acceptable to the Trustee, an Authenticating Agent
having an office in a Place of Payment designated by the Company with respect to
such series of Securities.

exercise every right and power of, the Company under this Indenture with the

Indenture Act as in effect at the date of the execution and delivery of this
Indenture or at any time thereafter shall be amended and

               (x)  if any such amendment shall require one or more changes to
          any provisions hereof or the inclusion herein of any additional
          provisions, or shall by operation of law be deemed to effect such
          changes or incorporate such provisions by reference or otherwise, this

considered as one class, by Act of said Holders delivered to the Company and the

<PAGE>
                                      -60-

Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to, or changing in any manner or eliminating any of the
provisions of, this Indenture or modifying in any manner the rights of the
Holders of Securities of such series under the Indenture; provided, however,
that if there shall be Securities of more than one series Outstanding hereunder
and if a proposed supplemental indenture shall directly affect the rights of the
Holders of Securities of one or more, but less than all, of such series, then
the consent only of the Holders of a majority in aggregate principal amount of
the Outstanding Securities of all series so directly affected, considered as one
class, shall be required; and provided, further, that if the Securities of any
series shall have been issued in more than one Tranche and if the proposed
supplemental indenture shall directly affect the rights of the Holders of
Securities of one or more, but less than all, of such Tranches, then the consent
only of the Holders of a majority in aggregate principal amount of the
Outstanding Securities of all Tranches so directly affected, considered as one
class, shall be required; and provided, further, that no such supplemental
indenture shall:

          (a) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon (or the amount of any
     installment of interest thereon) or change the method of calculating such
     rate or reduce any premium payable upon the redemption thereof, or reduce
     the amount of the principal of a Discount Security that would be due and
     payable upon a declaration of acceleration of the Maturity thereof pursuant
     to Section 802, or change the coin or currency (or other property), in
     which any Security or any premium or the interest thereon is payable, or
     impair the right to institute suit for the enforcement of any such payment
     on or after the Stated Maturity of any Security (or, in the case of
     redemption, on or after the Redemption Date), without, in any such case,
     the consent of the Holder of such Security, or

          (b) reduce the percentage in principal amount of the Outstanding
     Securities of any series, or any Tranche thereof, the consent of the
     Holders of which is required for any such supplemental indenture, or the
     consent of the Holders of which is required for any waiver of compliance
     with any provision of this Indenture or of any default hereunder and its
     consequences, or reduce the requirements of Section 1304 for quorum or
     voting, without, in any such case, the consent of the Holders of each
     Outstanding Security of such series or Tranche, or

          (c) modify any of the provisions of this Section, Section 607 or
     Section 813 with respect to the Securities of any series, or any Tranche
     thereof, except to increase the percentages in principal amount referred to
     in this Section or such other Sections or to provide that other provisions
     of this Indenture cannot be modified or waived without the consent of the
     Holder of each Outstanding Security affected thereby; provided, however,
     that this clause shall not be deemed to require the consent of any Holder
     with respect to changes in the references to "the Trustee" and concomitant
     changes in this Section, or the deletion of this proviso, in accordance
     with the requirements of Sections 911(b), 914 and 1201(h).

                                      -61-

          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 one or more
Tranches thereof, 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 or Tranche.

          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. A waiver by a
Holder of such Holder's right to consent under this Section shall be deemed to
be a consent of such Holder.

SECTION 1203.  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 901) 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, immunities or liabilities under this Indenture or
otherwise.

SECTION 1204.  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. Any supplemental indenture permitted by this Article may
restate this Indenture in its entirety, and, upon the execution and delivery
thereof, any such restatement shall supersede this Indenture as theretofore in
effect for all purposes.

SECTION 1205.  Conformity With Trust Indenture Act.

          Unless otherwise provided as contemplated by Section 301 with respect
to any series of Securities, every supplemental indenture executed pursuant to
this Article shall conform to the requirements of the Trust Indenture Act as
then in effect.

SECTION 1206.  Reference in Securities to Supplemental Indentures.

          Securities of any series, or any Tranche thereof, 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, or
any Tranche thereof, 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 or Tranche.

<PAGE>
                                      -62-

SECTION 1207.  Modification Without Supplemental Indenture.

          If the terms of any particular series of Securities shall have been
established in a Board Resolution or an Officer's Certificate as contemplated by
Section 301, and not in an indenture supplemental hereto, additions to, changes
in or the elimination of any of such terms may be effected by means of a
supplemental Board Resolution or Officer's Certificate, as the case may be,
delivered to, and accepted by, the Trustee; provided, however, that such
supplemental Board Resolution or Officer's Certificate shall not be accepted by
the Trustee or otherwise be effective unless all conditions set forth in this
Indenture which would be required to be satisfied if such additions, changes or
elimination were contained in a supplemental indenture shall have been
appropriately satisfied. Upon the acceptance thereof by the Trustee, any such
supplemental Board Resolution or Officer's Certificate shall be deemed to be a
"supplemental indenture" for purposes of Section 1204 and 1206.

                   Meetings of Holders; Action Without Meeting

SECTION 1301.  Purposes for Which Meetings May Be Called.

          A meeting of Holders of Securities of one or more, or all, series, or
any Tranche or Tranches thereof, may be called at any time and from time to time
pursuant to this Article to make, give or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be made, given or taken by Holders of Securities of such

     thereof, for any purpose specified in Section 1301, to be held at such time
     and at such place in the Borough of Manhattan, The City of New York, as the
     Trustee shall determine, or, with the approval of the Company, at any other
     place. Notice of every such meeting, 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, in the manner provided in Section 106, not
     less than 21 nor more than 180 days prior to the date fixed for the
     meeting.

          (b)  If the Trustee shall have been requested to call a meeting of the
     Holders of Securities of one or more, or all, series, or any Tranche or
     Tranches thereof, by the Company or by the Holders of 33% in aggregate
     principal amount of all of such series and Tranches, considered as one
     class, for any purpose specified in Section 1301, 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 21 days after receipt of such request or shall not thereafter
     proceed to cause the meeting to be held as provided herein, then the
     Company or the Holders of Securities of such series and Tranches in the
     amount above specified, as the case may be, may determine the time and the
     place in the Borough of Manhattan, The City of New York, or in such other

     place as shall be determined or approved by the Company, for such meeting
     and may call such meeting for such purposes by giving notice thereof as
     provided in Subsection (a) of this Section.

          (c)  Any meeting of Holders of Securities of one or more, or all,
     series, or any Tranche or Tranches thereof, shall be valid without notice
     if the Holders of all Outstanding Securities of such series or Tranches are
     present in person or by proxy and if representatives of the Company and the
     Trustee are present, or if notice is waived in writing before or after the
     meeting by the Holders of all Outstanding Securities of such series, or any
     Tranche or Tranches thereof, or by such of them as are not present at the
     meeting in person or by proxy, and by the Company and the Trustee.

SECTION 1303.  Persons Entitled to Vote at Meetings.

          To be entitled to vote at any meeting of Holders of Securities of one
or more, or all, series, or any Tranche or Tranches thereof, a Person shall be
(a) a Holder of one or more Outstanding Securities of such series or Tranches,
or (b) a Person appointed by an instrument in writing as proxy for a Holder or
Holders of one or more Outstanding Securities of such series or Tranches by such
Holder or Holders. The only Persons who shall be entitled to attend any meeting
of Holders of Securities of any series or Tranche shall be the Persons entitled
to vote at such meeting and their counsel, any representatives of the Trustee
and its counsel and any representatives of the Company and its counsel.

SECTION 1304.  Quorum; Action.

          The Persons entitled to vote a majority in aggregate principal amount
of the Outstanding Securities of the series and Tranches with respect to which a
meeting shall have been called as hereinbefore provided, considered as one
class, shall constitute a quorum for a meeting of Holders of Securities of such
series and Tranches; provided, however, that if any action is to be taken at
such meeting which this Indenture expressly provides may be taken by the Holders
of a specified percentage, which is less than a majority, in principal amount of
the Outstanding Securities of such series and Tranches, considered as one class,
the Persons entitled to vote such specified percentage in principal amount of
the Outstanding Securities of such series and Tranches, considered as one class,
shall constitute a quorum. In the absence of a quorum within one hour of the
time appointed for any such meeting, the meeting shall, if convened at the
request of Holders of Securities of such series and Tranches, be dissolved. In
any other case the meeting may be adjourned for such period as may be determined
by the chairman of the meeting prior to the adjournment of such meeting. In the
absence of a quorum at any such adjourned meeting, such adjourned meeting may be
further adjourned for such period as may be determined by the chairman of the
meeting prior to the adjournment of such adjourned meeting. Except as provided
by Section 1305(e), notice of the reconvening of any meeting adjourned for more
than 30 days shall be given as provided in Section 1302(a) not less than 10 days
prior to the date on which the meeting is scheduled to be reconvened. Notice of
the reconvening of an adjourned meeting shall state expressly the percentage, as
provided above, of the principal amount of the Outstanding Securities of such
series and Tranches which shall constitute a quorum.

          Except as limited by Section 1202, any resolution presented to a
meeting or adjourned meeting duly reconvened at which a quorum is present as
aforesaid may be adopted only by the affirmative vote of the Holders of a

<PAGE>
                                      -64-

majority in aggregate principal amount of the Outstanding Securities of the
series and Tranches with respect to which such meeting shall have been called,
considered as one class; provided, however, that, except as so limited, any
resolution with respect to any action which this Indenture expressly provides
may be taken by the Holders of a specified percentage, which is less than a
majority, in principal amount of the Outstanding Securities of such series and
Tranches, considered as one class, may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of such specified percentage in principal amount
of the Outstanding Securities of such series and Tranches, considered as one
class.

          Any resolution passed or decision taken at any meeting of Holders of
Securities duly held in accordance with this Section shall be binding on all the
Holders of Securities of the series and Tranches with respect to which such
meeting shall have been held, whether or not present or represented at the
meeting.

SECTION 1305.  Attendance at Meetings; Determination of Voting Rights;
               Conduct and Adjournment of Meetings.

          (a)  Attendance at meetings of Holders of Securities may be in person
     or by proxy; and, to the extent permitted by law, any such proxy shall
     remain in effect and be binding upon any future Holder of the Securities
     with respect to which it was given unless and until specifically revoked by
     the Holder or future Holder of such Securities before being voted.

          (b)  Notwithstanding any other provisions of this Indenture, the
     Trustee may make such reasonable regulations as it may deem advisable for
     any meeting of Holders of Securities in regard to proof of the holding of
     such Securities 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. Except as otherwise permitted or required by any
     such regulations, the holding of Securities shall be proved in the manner
     specified in Section 104 and the appointment of any proxy shall be proved
     in the manner specified in Section 104. Such regulations may provide that
     written instruments appointing proxies, regular on their face, may be
     presumed valid and genuine without the proof specified in Section 104 or
     other proof.

          (c)  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 as provided in Section 1302(b), in
     which case the Company or the Holders of Securities of the series and
     Tranches 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 vote of the Persons entitled
     to vote a majority in aggregate principal amount of the Outstanding
     Securities of all series and Tranches represented at the meeting,
     considered as one class.

          (d)  At any meeting each Holder or proxy shall be entitled to one vote
     for each $1 principal amount of Securities held or represented by him;
     provided, however, that no vote shall be cast or counted at any meeting in

<PAGE>
                                      -65-

     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, except as a Holder of a Security or proxy.

          (e)  Any meeting duly called pursuant to Section 1302 at which a
     quorum is present may be adjourned from time to time by Persons entitled to
     vote a majority in aggregate principal amount of the Outstanding Securities
     of all series and Tranches represented at the meeting, considered as one
     class; and the meeting may be held as so adjourned without further notice.

SECTION 1306.  Counting Votes and Recording Action of Meetings.

          The vote upon any resolution submitted to any meeting of Holders shall
be by written ballots on which shall be subscribed the signatures of the Holders
or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities, of the series and Tranches with respect
to which the meeting shall have been called, 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 of all votes cast at the meeting. A record 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 given as provided in Section 1302 and, if
applicable, Section 1304. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

SECTION 1307.  Action Without Meeting.

          In lieu of a vote of Holders at a meeting as hereinbefore contemplated
in this Article, any request, demand, authorization, direction, notice, consent,
waiver or other action may be made, given or taken by Holders by written
instruments as provided in Section 104.

indirectly through the Company or any predecessor or successor corporation,
because of the indebtedness hereby authorized or under or by reason of any of
the obligations, covenants or agreements contained in this Indenture or in any
of the Securities or to be implied herefrom or therefrom, and that any such
personal liability is hereby expressly waived and released as a condition of,
and as part of the consideration for, the execution of this Indenture and the
issuance of the Securities.
