Indebtedness of the Company.

determined;

         2.2.16 the manner in which the amounts of payment of principal of or

or financial index;

         2.2.17   the provisions, if any, relating to any security provided for

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

Section 2.3       Execution and Authentication.

         Two Officers shall sign the Securities for the Company by manual or
facsimile signature.

         If an Officer whose signature is on a Security no longer holds that
office at the time the Security is authenticated, the Security shall
nevertheless be valid.

         A Security shall not be valid until authenticated by the manual
signature of the Trustee or an authenticating agent. The signature shall be
conclusive evidence that the Security has been authenticated under this
Indenture.

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

                                       7
<PAGE>

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

         Prior to the issuance of Securities of any Series, the Trustee shall
have received and (subject to Section 7.2) shall be fully protected in relying
on: (a) the Board Resolution, supplemental indenture hereto or Officers'
Certificate establishing the form of the Securities of that Series or of
Securities within that Series and the terms of the Securities of that Series or
of Securities within that Series, (b) an Officers' Certificate complying with
Section 10.4, and (c) an Opinion of Counsel complying with Section 10.4.

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

         The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Securities. An authenticating agent may authenticate
Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate.

Section 2.4     Registrar and Paying Agent.

         The Company shall maintain, with respect to each Series of Securities,
at the place or places specified with respect to such Series pursuant to Section
2.2, an office or agency where Securities of such Series may be presented or
surrendered for payment ("Paying Agent"), where Securities of such Series may be
surrendered for registration of transfer or exchange ("Registrar") and where
notices and demands to or upon the Company in respect of the Securities of such
Series and this Indenture may be served ("Service Agent"). The Registrar shall
keep a register with respect to each Series of Securities and to their transfer
and exchange. The Company will give prompt written notice to the Trustee of the
name and address, and any change in the name or address, of each Registrar,
Paying Agent or Service Agent. If at any time the Company shall fail to maintain
any such required Registrar, Paying Agent or Service Agent or shall fail to
furnish the Trustee with the name and address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

         The Company may also from time to time designate one or more
co-registrars, additional paying agents or additional service agents and may
from time to time rescind such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligations to maintain a Registrar, Paying Agent and Service Agent in each
place so specified pursuant to Section 2.2 for Securities of any Series for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the name or address of any such
co-registrar, additional paying agent or additional service agent. The term
"Registrar" includes any co-registrar; the term "Paying Agent" includes any
additional paying agent; and the term "Service Agent" includes any additional
service agent.

         The Company hereby appoints the Trustee the initial Registrar, Paying
Agent and Service Agent for each Series unless another Registrar, Paying Agent
or Service Agent, as the case may be, is appointed prior to the time Securities
of that Series are first issued.

Section 2.5     Paying Agent to Hold Money in Trust.

         The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust, for the benefit of
Securityholders of any Series of Securities, or the Trustee, all money held by
the Paying Agent for the payment of principal of or interest on the Series of
Securities, and will notify the Trustee of any default by the Company in making
any such payment. While any such default continues, the Trustee may require a
Paying Agent to pay all money held by it to the Trustee. The Company at any time
may require a Paying Agent to pay all money held by it to the Trustee. Upon
payment over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) shall have no further liability for the money. If the Company or a
Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of Securityholders of any Series of Securities all money
held by it as Paying Agent.

                                       8

Section 2.6      Securityholder Lists.

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Securityholders of each Series of Securities and shall otherwise comply with TIA
Section 312(a). If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least ten days before each interest payment date and at such
other times as the Trustee may request in writing a list, in such form and as of
such date as the Trustee may reasonably require, of the names and addresses of
Securityholders of each Series of Securities.

Section 2.7      Transfer and Exchange.

         Where Securities of a Series are presented to the Registrar or a
co-registrar with a request to register a transfer or to exchange them for an
equal principal amount of Securities of the same Series, the Registrar shall
register the transfer or make the exchange if its requirements for such
transactions are met. To permit registrations of transfers and exchanges, the
Trustee shall authenticate Securities at the Registrar's request. No service
charge shall be made for any registration of transfer or exchange (except as
otherwise expressly permitted herein), but the Company may require payment of a
sum sufficient to cover any transfer tax or similar governmental charge payable
in connection therewith (other than any such transfer tax or similar
governmental charge payable upon exchanges pursuant to Sections 2.11, 3.6 or
9.6).

         Neither the Company nor the Registrar shall be required (a) to issue,
register the transfer of, or exchange Securities of any Series for the period
beginning at the opening of business fifteen days immediately preceding the
mailing of a notice of redemption of Securities of that Series selected for
redemption and ending at the close of business on the day of such mailing, or
(b) to register the transfer of or exchange Securities of any Series selected,
called or being called for redemption as a whole or the portion being redeemed
of any such Securities selected, called or being called for redemption in part.

Section 2.8      Mutilated, Destroyed, Lost and Stolen Securities.

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

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and make available for delivery, in lieu of any such destroyed,
lost or stolen Security, a new Security of the same Series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

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

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

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

                                       9
<PAGE>

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

Section 2.9    Outstanding Securities.

         The Securities outstanding at any time are all the Securities
authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest on a Global Security
effected by the Trustee in accordance with the provisions hereof and those
described in this Section as not outstanding.

         If a Security is replaced pursuant to Section 2.8, it ceases to be
outstanding until the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

         If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds on the Maturity of Securities of a Series money
sufficient to pay such Securities payable on that date, then on and after that
date such Securities of the Series cease to be outstanding and interest on them
ceases to accrue.

         A Security does not cease to be outstanding because the Company or an
Affiliate holds the Security.

         In determining whether the Holders of the requisite principal amount of
outstanding Securities have given any request, demand, authorization, direction,
notice, consent or waiver hereunder, the principal amount of a Discount Security
that shall be deemed to be outstanding for such purposes shall be the amount of
the principal thereof that would be due and payable as of the date of such
determination upon a declaration of acceleration of the Maturity thereof
pursuant to Section 6.2.

Section 2.10    Treasury Securities.

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

Section 2.11    Temporary Securities.

         Until definitive Securities are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Securities upon a Company
Order. Temporary Securities shall be substantially in the form of definitive
Securities but may have variations that the Company considers appropriate for
temporary Securities. Without unreasonable delay, the Company shall prepare and
the Trustee upon request shall authenticate definitive Securities of the same
Series and date of maturity in exchange for temporary Securities. Until so
exchanged, temporary securities shall have the same rights under this Indenture
as the definitive Securities.

Section 2.12    Cancellation.

         The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for registration of transfer, exchange or
payment. The Trustee shall cancel all Securities surrendered for transfer,
exchange, payment, replacement or cancellation and shall destroy such canceled
Securities (subject to the record retention requirement of the Exchange Act) and
deliver a certificate of such destruction to the Company, unless the Company
otherwise directs. The Company may not issue new Securities to replace
Securities that it has paid or delivered to the Trustee for cancellation.

Section 2.13    Defaulted Interest.

         If the Company defaults in a payment of interest on a Series of
Securities, it shall pay the defaulted interest, plus, to the extent permitted
by law, any interest payable on the defaulted interest, to the persons who are
Securityholders of the Series on a subsequent special record date. The Company
shall fix the record date and payment date. At least 30 days before the record
date, the Company shall mail to the Trustee and to each Securityholder of the
Series a notice that states the record date, the payment date and the amount of
interest to be paid. The Company may pay defaulted interest in any other lawful
manner.

Section 2.14    Global Securities.

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

         2.14.2   Transfer and Exchange. Notwithstanding any provisions to the
contrary contained in Section 2.7 of the Indenture and in addition thereto, any
Global Security shall be exchangeable pursuant to Section 2.7 of the Indenture
for Securities registered in the names of Holders other than the Depository for
such Security or its nominee only if (i) such Depository notifies the Company
that it is unwilling or unable to continue as Depository for such Global
Security or if at any time such Depository ceases to be a clearing agency
registered under the Exchange Act, and, in either case, the Company fails to
appoint a successor Depository within 90 days of such event, (ii) the Company
executes and delivers to the Trustee an Officers' Certificate to the effect that
such Global Security shall be so exchangeable or (iii) an Event of Default with
respect to the Securities represented by such Global Security shall have
happened and be continuing. Any Global Security that is exchangeable pursuant to
the preceding sentence shall be exchangeable for Securities registered in such
names as the Depository shall direct in writing in an aggregate principal amount
equal to the principal amount of the Global Security with like tenor and terms.

         Except as provided in this Section 2.14.2, a Global Security may not be
transferred except as a whole by the Depository with respect to such Global
Security to a nominee of such Depository, by a nominee of such Depository to
such Depository or another nominee of such Depository or by the Depository or
any such nominee to a successor Depository or a nominee of such a successor
Depository.

         2.14.3   Legend. Unless otherwise provided pursuant to Section 2.2, any
Global Security issued hereunder shall bear a legend in substantially the
following form:

         "This Security is a Global Security within the meaning of the Indenture
hereinafter referred to and is registered in the name of the Depository or a
nominee of the Depository. This Security is exchangeable for Securities
registered in the name of a person other than the Depository or its nominee only
in the limited circumstances described in the Indenture, and may not be
transferred except as a whole by the Depository to a nominee of the Depository,
by a nominee of the Depository to the Depository or another nominee of the
Depository or by the Depository or any such nominee to a successor Depository or
a nominee of such a successor Depository."

         2.14.4   Acts of Holders. The Depository, as a Holder, may appoint
agents and otherwise authorize participants to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action which a Holder
is entitled to give or take under the Indenture.

         2.14.5   Payments. Notwithstanding the other provisions of this
Indenture, unless otherwise specified as contemplated by Section 2.2, payment of
the principal of, premium, if any, and interest, if any, on any Global Security
shall be made to the Holder thereof.

         2.14.6   Consents, Declaration and Directions. Except as provided in
Section 2.14.5, the Company, the Trustee and any Agent shall treat a person as
the Holder of such principal amount of outstanding Securities of such Series
represented by a Global Security as shall be specified in a written statement of
the Depositary with respect to such Global Security, for purposes of obtaining
any consents, declarations, waivers or directions required to be given by the
Holders pursuant to this Indenture.

Section 2.15     CUSIP Numbers.

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other elements of
identification printed on the Securities, and any such redemption shall not be
affected by any defect in or omission of such numbers.

                                   REDEMPTION

Section 3.1       Notice to Trustee.

         The Company may, with respect to any Series of Securities, reserve the
right to redeem and pay the Series of Securities or may covenant to redeem and
pay the Series of Securities or any part thereof prior to the Stated Maturity
thereof at such time and on such terms as provided for in such Securities. If a
Series of Securities is redeemable and the Company wants or is obligated to
redeem prior to the Stated Maturity thereof all or part of the Series of
Securities pursuant to the terms of such Securities, it shall notify the Trustee
of the redemption date and the principal amount of Series of Securities to be
redeemed. The Company shall give the notice at least 45 days before the
redemption date (or such shorter notice as may be acceptable to the Trustee).

Section 3.2      Selection of Securities to be Redeemed.

         Unless otherwise indicated for a particular Series by a Board
Resolution, a supplemental indenture or an Officers' Certificate, if less than
all the Securities of a Series are to be redeemed, the Trustee shall select the
Securities of the Series to be redeemed in any manner that the Trustee deems
fair and appropriate. The Trustee shall make the selection from Securities of
the Series outstanding not previously called for redemption. The Trustee may
select for redemption portions of the principal of Securities of the Series that
have denominations larger than $1,000. Securities of the Series and portions of
them it selects shall be in amounts of $1,000 or whole multiples of $1,000 or,
with respect to Securities of any Series issuable in other denominations
pursuant to Section 2.2.10, the minimum principal denomination for each Series
and integral multiples thereof. Provisions of this Indenture that apply to
Securities of a Series called for redemption also apply to portions of
Securities of that Series called for redemption.

Section 3.3     Notice of Redemption.

         Unless otherwise indicated for a particular Series by Board Resolution,
a supplemental indenture hereto or an Officers' Certificate, at least 30 days
but not more than 60 days before a redemption date, the Company shall mail a
notice of redemption by first-class mail to each Holder whose Securities are to
be redeemed and if any Bearer Securities are outstanding, publish on one
occasion a notice in an Authorized Newspaper.

         The notice shall identify the Securities of the Series to be redeemed
and shall state:

         (a)    the redemption date;

         (b)    the redemption price;

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

         (d)    that Securities of the Series called for redemption must be
surrendered to the Paying Agent to collect the redemption price;

         (e)    that interest on Securities of the Series called for
redemption ceases to accrue on and after the redemption date; and

         (f)    any other information as may be required by the terms of the
particular Series or the Securities of a Series being redeemed.

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

Section 3.4     Effect of Notice of Redemption.

         Once notice of redemption is mailed or published as provided in Section
3.3, Securities of a Series called for redemption become due and payable on the
redemption date and at the redemption price. A notice of redemption may not be
conditional. Upon surrender to the Paying Agent, such Securities shall be paid
at the redemption price plus accrued interest to the redemption date.

Section 3.5       Deposit of Redemption Price.

         On or before the redemption date, the Company shall deposit with the
Paying Agent money sufficient to pay the redemption price of and accrued
interest, if any, on all Securities to be redeemed on that date.

Section 3.6       Securities Redeemed in Part.

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

                                   ARTICLE IV
                                    COVENANTS

Section 4.1     Payment of Principal and Interest.

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

Section 4.2     SEC Reports.

         The Company shall deliver to the Trustee within 15 days after it files
them with the SEC copies of the annual reports and of the information,
documents, and other reports (or copies of such portions of any of the foregoing
as the SEC may by rules and regulations prescribe) which the Company is required
to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The
Company also shall comply with the other provisions of TIA Section 314(a).

Section 4.3     Compliance Certificate.

         The Company shall deliver to the Trustee, within 90 days after the end
of each fiscal year of the Company, an Officers' Certificate stating that a
review of the activities of the Company and its Subsidiaries during the
preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to the best of
his knowledge the Company has kept, observed, performed and fulfilled each and
every covenant contained in this Indenture and is not in default in the
performance or observance of any of the terms, provisions and conditions hereof
(or, if a Default or Event of Default shall have occurred, describing all such
Defaults or Events of Default of which he may have knowledge).

         The Company will, so long as any of the Securities are outstanding,
deliver to the Trustee, forthwith upon becoming aware of any Default or Event of
Default, an Officers' Certificate specifying such Default or Event of Default
and what action the Company is taking or proposes to take with respect thereto.

Section 4.4     Stay, Extension and Usury Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture or the Securities; and the Company (to the
extent it may lawfully do so) hereby expressly waives all benefit or advantage
of any such law and covenants that it will not, by resort to any such law,
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 has been enacted.

Section 4.5     Corporate Existence.

         Subject to Article V, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and the corporate, partnership or other existence of each Significant
Subsidiary in accordance with the respective organizational documents of each
Significant Subsidiary and the rights (charter and statutory), licenses and
franchises of the Company and its Significant Subsidiaries; provided, however,
that the Company shall not be required to preserve any such right, license or
franchise, or the corporate, partnership or other existence of any Significant
Subsidiary, if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Subsidiaries taken as a whole and that the loss thereof is not adverse in
any material respect to the Holders.

transfer or lease all or substantially all of its properties and assets to, any

convey, transfer or lease its properties and assets substantially as an entirety
to, the Company, unless:

         (a)    the successor person (if any) is a corporation, partnership,

consolidation or into or with which the Company is merged or to which such sale,
lease, conveyance or other disposition is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor person has been named

period of 30 days); or

there has been given, by registered or certified mail, to the Company by the
Trustee or to the Company and the Trustee by the Holders of at least 25% in
principal amount of the outstanding Securities of that Series a written notice
specifying such default or breach and requiring it to be remedied and stating
that such notice is a "Notice of Default" hereunder; or

         (e) the Company or any of its Significant Subsidiaries pursuant to or
within the meaning of any Bankruptcy Law:

                  (i) commences a voluntary case,

                  (ii) consents to the entry of an order for relief against it
in an involuntary case,

Section 6.2       Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default with respect to Securities of any Series at the
time outstanding occurs and is continuing (other than an Event of Default
referred to in Section 6.1(e) or (f)) then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the outstanding Securities
of that Series may declare the principal amount (or, if any Securities of that
Series are Discount Securities, such portion of the principal amount as may be
specified in the terms of such Securities) of and accrued and unpaid interest,
if any, on all of the Securities of that Series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) and accrued and unpaid interest, if any, shall become immediately due
and payable. If an Event of Default specified in Section 6.1(e) or (f) shall
occur, the principal amount (or specified amount) of and accrued and unpaid
interest, if any, on all outstanding Securities shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder.

                                       15
<PAGE>

         At any time after such a declaration of acceleration with respect to
any Series has been made and before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in principal amount of the outstanding
Securities of that Series, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if:

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

                  (i) all overdue interest, if any, on all Securities of that
         Series,

                  (ii) the principal of any Securities of that 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,

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

                  (iv) all sums paid or advanced by the Trustee hereunder and
         the reasonable compensation, expenses, disbursements and advances of
         the Trustee, its agents and counsel;

and

         (b) all Events of Default with respect to Securities of that Series,
other than the non-payment of the principal of Securities of that Series which
have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 6.13.

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

Section 6.3     Collection of Indebtedness and Suits for Enforcement by Trustee.

         The Company covenants that if

         (a) default is made in the payment of any interest on any Security when
such interest becomes due and payable and such default continues for a period of
30 days, or

         (b) default is made in the payment of principal of any Security at the
Maturity thereof, or

         (c) default is made in the deposit of any sinking fund payment when and
as due by the terms of a Security, then, the Company will, upon demand of the
Trustee, pay to it, for the benefit of the Holders of such Securities, the whole
amount then due and payable on such Securities for principal and interest and,
to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal or any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may 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 deemed 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 any Securities of any Series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
Series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

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

         (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same, and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.7.

         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 6.5       Trustee May Enforce Claims Without Possession of Securities.

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

Section 6.6       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 interest,
upon presentation of the Securities and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

         First:               To the payment of all amounts due the Trustee
under Section 7.7; and

         Second: To the payment of the amounts then due and unpaid for principal
of and interest on the Securities in respect of which or for the benefit of
which such money has been collected, ratably, without preference or priority of

principal and interest, respectively; and

         Third:               To the Company.

Section 6.7       Limitation on Suits.

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

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

                                       17
<PAGE>

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

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

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

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

it being understood and intended that no one or more of such Holders 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 such
Holders.

Section 6.8       Unconditional Right of Holders to Receive Principal 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 interest, if any, on such Security on
the Stated Maturity or Stated Maturities expressed in such Security (or, in the
case of redemption, on the redemption date) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

Section 6.9       Restoration of Rights and Remedies.

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

Section 6.10      Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in Section 2.8, 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 6.11      Delay or Omission Not Waiver.

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

Section 6.12      Control by Holders.

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

                                       18
<PAGE>

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

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

         (c) subject to the provisions of Section 6.1, the Trustee shall have
the right to decline to follow any such direction if the Trustee in good faith
shall, by a Responsible Officer of the Trustee, determine that the proceeding so
directed would involve the Trustee in personal liability.

Section 6.13      Waiver of Past Defaults.

         Subject to Section 6.2, 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 in
the payment of the principal of or interest on any Security of such Series
(provided, however, that the Holders of a majority in principal amount of the
outstanding Securities of any Series may rescind an acceleration and its
consequences, including any related payment default that resulted from such
acceleration). Upon any such waiver, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon.

Section 6.14      Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security 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 principal
amount of the outstanding Securities of any Series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of or interest on
any Security on or after the Stated Maturity or Stated Maturities expressed in
such Security (or, in the case of redemption, on the redemption date).

                                   ARTICLE VII
                                     TRUSTEE

Section 7.1       Duties of Trustee.

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

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

                  (i) The Trustee need perform only those duties that are
         specifically set forth in this Indenture and no others.

                  (ii) In the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon Officers'
         Certificates or Opinions of Counsel furnished to the Trustee and
         conforming to the requirements of this Indenture; however, in the case
         of any such Officers' Certificates or Opinions of Counsel which by any
         provisions hereof are specifically required to be furnished to the
         Trustee, the Trustee shall examine such Officers' Certificates and
         Opinions of Counsel to determine whether or not they conform to the
         requirements of this Indenture.

                                       19
<PAGE>

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

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

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

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

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

         (e) The Trustee may refuse to perform any duty or exercise any right or
power unless it receives indemnity satisfactory to it against any loss,
liability or expense.

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

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

         (h) The Paying Agent, the Registrar and any authenticating agent shall
be entitled to the protections and immunities as are set forth in paragraphs
(a), (b) and (c) of this Section with respect to the Trustee.

Section 7.2       Rights of Trustee.

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

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

         (c) The Trustee may act through agents and shall not be responsible for
the misconduct or negligence of any agent appointed with due care. No Depository
shall be deemed an agent of the Trustee and the Trustee shall not be responsible
for any act or omission by any Depository.

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

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

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

Section 7.3       Individual Rights of Trustee.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or an
Affiliate with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. The Trustee is also subject to Sections 7.10
and 7.11.

Section 7.4       Trustee's Disclaimer.

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

Section 7.5       Notice of Defaults.

         If a Default or Event of Default occurs and is continuing with respect
to the Securities of any Series and if it is known to a Responsible Officer of
the Trustee, the Trustee shall mail to each Securityholder of the Securities of
that Series and, if any Bearer Securities are outstanding, publish on one
occasion in an Authorized Newspaper, notice of a Default or Event of Default
within 90 days after it occurs or, if later, after a Responsible Officer of the
Trustee has knowledge of such Default or Event of Default. Except in the case of
a Default or Event of Default in payment of principal of or interest on any
Security of any Series, the Trustee may withhold the notice if and so long as
its corporate trust committee or a committee of its Responsible Officers in good
faith determines that withholding the notice is in the interests of
Securityholders of that Series.

Section 7.6       Reports by Trustee to Holders.

         Within 60 days after May 15 in each year, the Trustee shall transmit by
mail to all Securityholders, as their names and addresses appear on the register
kept by the Registrar and, if any Bearer Securities are outstanding, publish in
an Authorized Newspaper, a brief report dated as of such May 15, in accordance
with, and to the extent required under, TIA Section 313.

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

Section 7.7       Compensation and Indemnity.

         The Company shall pay to the Trustee from time to time reasonable
compensation for its services. The Trustee's compensation shall not be limited
by any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred by it. Such expenses shall include the reasonable compensation and
expenses of the Trustee's agents and counsel.

         The Company shall indemnify the Trustee (including the cost of
defending itself) against any loss, liability or expense incurred by it except
as set forth in the next paragraph in the performance of its duties under this
Indenture as Trustee or Agent. The Trustee shall notify the Company promptly of
any claim for which it may seek indemnity. The Company shall defend the claim
and the Trustee shall cooperate in the defense. The Trustee may have separate
counsel and the Company shall pay the reasonable fees and expenses of such
counsel. The Company need not pay for any settlement made without its consent,
which consent shall not be unreasonably withheld. This indemnification shall
apply to officers, directors, employees, shareholders and agents of the Trustee.

         The Company need not reimburse any expense or indemnify against any
loss or liability incurred by the Trustee or by any officer, director, employee,
shareholder or agent of the Trustee through negligence or bad faith.

         To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities of any Series on all money or
property held or collected by the Trustee, except that held in trust to pay
principal and interest on particular Securities of that Series.

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

Section 7.8       Replacement of Trustee.

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

         The Trustee may resign with respect to the Securities of one or more
Series by so notifying the Company. The Holders of a majority in principal
amount of the Securities of any Series may remove the Trustee with respect to
that Series by so notifying the Trustee and the Company. The Company may remove
the Trustee with respect to Securities of one or more Series if:

         (a) the Trustee fails to comply with Section 7.10;

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

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

         (d) the Trustee becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Securities may appoint
a successor Trustee to replace the successor Trustee appointed by the Company.

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

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

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer all property held by it as Trustee to the
successor Trustee subject to the lien provided for in Section 7.7, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
with respect to each Series of Securities for which it is acting as Trustee
under this Indenture. A successor Trustee shall mail a notice of its succession
to each Securityholder of each such Series and, if any Bearer Securities are
outstanding, publish such notice on one occasion in an Authorized Newspaper.
Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the
Company's obligations under Section 7.7 hereof shall continue for the benefit of
the retiring trustee with respect to expenses and liabilities incurred by it
prior to such replacement.

Section 7.9       Successor Trustee by Merger, etc.

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

Section 7.10      Eligibility; Disqualification.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1), (2) and (5). The Trustee shall always
have a combined capital and surplus of at least $25,000,000 as set forth in its
most recent published annual report of condition. The Trustee shall comply with
TIA Section 310(b).

Section 7.11      Preferential Collection of Claims Against Company.

         The Trustee is subject to TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated.

                                  ARTICLE VIII
                     SATISFACTION AND DISCHARGE; DEFEASANCE

Section 8.1       Satisfaction and Discharge of Indenture.

         This Indenture shall upon Company Order cease to be of further effect
(except as hereinafter provided in this Section 8.1), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

         (a) either

                  (i) all Securities theretofore authenticated and delivered
         (other than Securities that have been destroyed, lost or stolen and
         that have been replaced or paid) have been delivered to the Trustee for
         cancellation; or

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

                  Maturity within one year, or

                           (3) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Company, or

                           (4) are deemed paid and discharged pursuant to
                  Section 8.3, as applicable;

and the Company, in the case of (1), (2) or (3) above, has deposited or caused
to be deposited with the Trustee as trust funds in trust an amount sufficient
for the purpose of paying and discharging the entire indebtedness on such
Securities not theretofore delivered to the Trustee for cancellation, for
principal and interest to the date of such deposit (in the case of Securities
which have become due and payable on or prior to the date of such deposit) or to
the Stated Maturity or redemption date, as the case may be;

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

         (c) the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 7.7, and, if money shall
have been deposited with the Trustee pursuant to clause (a) of this Section, the
provisions of Sections 2.4, 2.7, 2.8, 8.1 8.2 and 8.5 shall survive.

Section 8.2       Application of Trust Funds; Indemnification.

         (a) Subject to the provisions of Section 8.5, all money deposited with
the Trustee pursuant to Section 8.1, all money and U.S. Government Obligations
or Foreign Government Obligations deposited with the Trustee pursuant to Section
8.3 or 8.4 and all money received by the Trustee in respect of U.S. Government
Obligations or Foreign Government Obligations deposited with the Trustee
pursuant to Section 8.3 or 8.4, shall be held in trust and applied by it, in
accordance with the provisions of the Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the persons
entitled thereto, of the principal and interest for whose payment such money has
been deposited with or received by the Trustee or to make mandatory sinking fund
payments or analogous payments as contemplated by Sections 8.3 or 8.4.

                                       23
<PAGE>

         (b) The Company shall pay and shall indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against U.S. Government
Obligations or Foreign Government Obligations deposited pursuant to Sections 8.3
or 8.4 or the interest and principal received in respect of such obligations
other than any payable by or on behalf of Holders.

         (c) The Trustee shall deliver or pay to the Company from time to time
upon Company Request any U.S. Government Obligations or Foreign Government
Obligations or money held by it as provided in Sections 8.3 or 8.4 which, in the
opinion of a nationally recognized firm of independent certified public
accountants expressed in a written certification thereof delivered to the
Trustee, are then in excess of the amount thereof which then would have been
required to be deposited for the purpose for which such U.S. Government
Obligations or Foreign Government Obligations or money were deposited or
received. This provision shall not authorize the sale by the Trustee of any U.S.
Government Obligations or Foreign Government Obligations held under this
Indenture.

Section 8.3       Legal Defeasance of Securities of any Series.

         Unless this Section 8.3 is otherwise specified, pursuant to Section
2.2.21, to be inapplicable to Securities of any Series, the Company shall be
deemed to have paid and discharged the entire indebtedness on all the
outstanding Securities of such Series on the 91st day after the date of the
deposit referred to in subparagraph (d) hereof, and the provisions of this
Indenture, as it relates to such outstanding Securities of such Series, shall no
longer be in effect (and the Trustee, at the expense of the Company, shall, at
Company Request, execute proper instruments acknowledging the same), except as
to:

         (a) the rights of Holders of Securities of such Series to receive, from
the trust funds described in subparagraph (d) hereof, (i) payment of the
principal of and each installment of principal of and interest on the
outstanding Securities of such Series on the Stated Maturity of such principal

of preferring the Holders of the Securities of such Series over any other

contained in a supplemental indenture hereto for a particular Series of

to Section 2.2.21 (and the failure to comply with any such covenants shall not

Default or Event of Default hereunder, with respect to the Securities of such
Series, provided that the following conditions shall have been satisfied:

caused to be irrevocably deposited (except as provided in Section 8.2(c)) with

Section 8.5       Repayment to Company.

         The Trustee and the Paying Agent shall pay to the Company upon request
any money held by them for the payment of principal and interest that remains
unclaimed for two years. After that, Securityholders entitled to the money must
look to the Company for payment as general creditors unless an applicable
abandoned property law designates another person.

Section 8.6       Reinstatement.

         If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Sections 8.1, 8.3 or 8.4, as the case
may be, by reason of any legal proceeding or by reason of any order or judgment
of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, the Company's obligations under this Indenture and
the Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.1, 8.3 or 8.4, as the case may be, until such time as the
Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with Section 8.1, 8.3 or 8.4, as the case may be;
provided, however, that if the Company makes any payment of principal of,
premium, if any, or interest on any Securities because of reinstatement of its
obligations, the Company shall be subrogated to the rights of the holders of
such Securities to receive such payment from the money or U.S. Government
Obligations held by the Trustee or Paying Agent.

                             AMENDMENTS AND WAIVERS

Section 9.1       Without Consent of Holders.

         The Company and the Trustee may amend or supplement this Indenture or
the Securities of one or more Series without the consent of any Securityholder:

         (a) to cure any ambiguity, defect or inconsistency;

         (b) to comply with Article V;

         (c) to provide for uncertificated Securities in addition to or in place
of certificated Securities;

         (d) to make any change that does not adversely affect the rights of any
Securityholder;

         (e) to provide for the issuance of and establish the form and terms and
conditions of Securities of any Series as permitted by this Indenture;

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

         (g)      to comply with requirements of the SEC in order to effect or
maintain the qualification of this Indenture under the TIA.

Section 9.2       With Consent of Holders.

         The Company and the Trustee may enter into a supplemental indenture
with the written consent of the Holders of at least a majority in principal
amount of the outstanding Securities of each Series affected by such
supplemental indenture (including consents obtained in connection with a tender
offer or exchange offer for the Securities of such Series), for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture or of modifying in
any manner the rights of the Securityholders of each such Series. Except as
provided in Section 6.13, the Holders of at least a majority in principal amount
of the outstanding Securities of each Series affected by such waiver by notice
to the Trustee (including consents obtained in connection with a tender offer or
exchange offer for the Securities of such Series) may waive compliance by the
Company with any provision of this Indenture or the Securities with respect to
such Series.

                                       26
<PAGE>

         It shall not be necessary for the consent of the Holders of Securities
under this Section 9.2 to approve the particular form of any proposed
supplemental indenture or waiver, but it shall be sufficient if such consent
approves the substance thereof. After a supplemental indenture or waiver under
this Section becomes effective, the Company shall mail to the Holders of
Securities affected thereby and, if any Bearer Securities affected thereby are
outstanding, publish on one occasion in an Authorized Newspaper, a notice
briefly describing the supplemental indenture or waiver. Any failure by the
Company to mail or publish such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture or waiver.

Section 9.3       Limitations.

         Without the consent of each Securityholder affected, an amendment or
waiver may not:

         (a) change the amount of Securities whose Holders must consent to an
amendment, supplement or waiver;

         (b) reduce the rate of or extend the time for payment of interest
(including default interest) on any Security;

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

         (d) reduce the principal amount of Discount Securities payable upon
acceleration of the maturity thereof;

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

         (f) make the principal of or interest, if any, on any Security payable
in any currency other than that stated in the Security;

         (g)      make any change in Sections 6.8, 6.13, 9.3 (this sentence),
10.15 or 10.16; or

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

Section 9.4       Compliance with Trust Indenture Act.

         Every amendment to this Indenture or the Securities of one or more
Series shall be set forth in a supplemental indenture hereto that complies with
the TIA as then in effect.

Section 9.5       Revocation and Effect of Consents.

         Until an amendment or waiver becomes effective, a consent to it by a
Holder of a Security is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if notation of the consent is not made on
any Security. However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of a Security if the Trustee receives the
notice of revocation before the date the amendment or waiver becomes effective.

                                       27
<PAGE>

         Any amendment or waiver once effective shall bind every Securityholder
of each Series affected by such amendment or waiver unless it is of the type
described in any of clauses (a) through (g) of Section 9.3. In that case, the
amendment or waiver shall bind each Holder of a Security who has consented to it
and every subsequent Holder of a Security or portion of a Security that
evidences the same debt as the consenting Holder's Security.

Section 9.6       Notation on or Exchange of Securities.

         The Trustee may place an appropriate notation about an amendment or
waiver on any Security of any Series thereafter authenticated. The Company in
exchange for Securities of that Series may issue and the Trustee shall
authenticate upon request new Securities of that Series that reflect the
amendment or waiver.

Section 9.7       Trustee Protected.

         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 7.1) 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 shall sign all
supplemental indentures, except that the Trustee need not sign any supplemental
indenture that adversely affects its rights.

Section 10.15     Securities in a Foreign Currency or in ECU.

         Unless otherwise specified in a Board Resolution, a supplemental
indenture hereto or an Officers' Certificate delivered pursuant to Section 2.2
of this Indenture with respect to a particular Series of Securities, whenever
for purposes of this Indenture any action may be taken by the Holders of a
specified percentage in aggregate principal amount of Securities of all Series
or all Series affected by a particular action at the time outstanding and, at
such time, there are outstanding Securities of any Series which are denominated
in a coin or currency other than Dollars (including ECUs), then the principal
amount of Securities of such Series which shall be deemed to be outstanding for
the purpose of taking such action shall be that amount of Dollars that could be
obtained for such amount at the Market Exchange Rate at such time. For purposes
of this Section 10.15, "Market Exchange Rate" shall mean the noon Dollar buying
rate in New York City for cable transfers of that currency as published by the
Federal Reserve Bank of New York; provided, however, in the case of ECUs, Market
Exchange Rate shall mean the rate of exchange determined by the Commission of
the European Union (or any successor thereto) as published in the Official
Journal of the European Union (such publication or any successor publication,
the "Journal"). If such Market Exchange Rate is not available for any reason
with respect to such currency, the Trustee shall use, in its sole discretion and
without liability on its part, such quotation of the Federal Reserve Bank of New
York or, in the case of ECUs, the rate of exchange as published in the Journal,
as of the most recent available date, or quotations or, in the case of ECUs,
rates of exchange from one or more major banks in The City of New York or in the
country of issue of the currency in question or, in the case of ECUs, in
Luxembourg or such other quotations or, in the case of ECUs, rates of exchange
as the Trustee, upon consultation with the Company, shall deem appropriate. The
provisions of this paragraph shall apply in determining the equivalent principal
amount in respect of Securities of a Series denominated in currency other than
Dollars in connection with any action taken by Holders of Securities pursuant to
the terms of this Indenture.

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

Section 10.16     Judgment Currency.

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

Section 11.1      Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of the Securities of a Series, except as otherwise permitted
or required by any form of Security of such Series issued pursuant to this
Indenture.

         The minimum amount of any sinking fund payment provided for by the
terms of the Securities of any Series is herein referred to as a "mandatory
sinking fund payment" and any other amount provided for by the terms of
Securities of such Series is herein referred to as an "optional sinking fund
payment." If provided for by the terms of Securities of any Series, the cash
amount of any sinking fund payment may be subject to reduction as provided in
Section 11.2. Each sinking fund payment shall be applied to the redemption of
Securities of any Series as provided for by the terms of the Securities of such
Series.

Section 11.2      Satisfaction of Sinking Fund Payments with Securities.

         The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any Series to be made pursuant to the
terms of such Securities (1) deliver outstanding Securities of such Series to
which such sinking fund payment is applicable (other than any of such Securities
previously called for mandatory sinking fund redemption) and (2) apply as credit
Securities of such Series to which such sinking fund payment is applicable and
which have been redeemed either at the election of the Company pursuant to the
terms of such Series of Securities (except pursuant to any mandatory sinking
fund) or through the application of permitted optional sinking fund payments or
other optional redemptions pursuant to the terms of such Securities, provided
that such Securities have not been previously so credited. Such Securities shall
be received by the Trustee, together with an Officers' Certificate with respect
thereto, not later than 15 days prior to the date on which the Trustee begins
the process of selecting Securities for redemption, and shall be credited for
such purpose by the Trustee at the price specified in such Securities for
redemption through operation of the sinking fund and the amount of such sinking
fund payment shall be reduced accordingly. If as a result of the delivery or

the aforesaid cash payment shall be less than $100,000, the Trustee need not
call Securities of such Series for redemption, except upon receipt of a Company
Order that such action be taken, and such cash payment shall be held by the
Trustee or a Paying Agent and applied to the next succeeding sinking fund
payment, provided, however, that the Trustee or such Paying Agent shall from
time to time upon receipt of a Company Order pay over and deliver to the Company
any cash payment so being held by the Trustee or such Paying Agent upon delivery

Company having an unpaid principal amount equal to the cash payment required to

a particular Series of Securities) prior to each sinking fund payment date for
any Series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that Series pursuant to the terms of that Series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that Series pursuant to Section 11.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 30 days (unless otherwise indicated in the Board Resolution,

Series of Securities) 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 3.2 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the

stated in Sections 3.4, 3.5 and 3.6.

                                   ARTICLE XII
                           SUBORDINATION OF SECURITIES

Section 12.1      Agreement of Subordination.

         The Company covenants and agrees, and each Holder of Securities issued
hereunder by his acceptance thereof likewise covenants and agrees, that all
Securities shall be issued subject to the provisions of this Article XII; and
each Person holding any Security, whether upon original issue or upon transfer,
assignment or exchange thereof, accepts and agrees to be bound by such
provisions.

         The payment of the principal of, premium, if any, and interest on all
Securities (including, but not limited to, the redemption price with respect to
the Securities called for redemption in accordance with Article 3 as provided in
the Indenture) issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and subject in right of payment to the
prior payment in full of all Senior Indebtedness, whether outstanding at the
date of this Indenture or thereafter incurred.

         No provision of this Article XII shall prevent the occurrence of any
default or Event of Default hereunder.

Section 12.2      Payments to Holders.

         No payment shall be made with respect to the principal of, or premium,
if any, or interest on the Securities (including, but not limited to, the
redemption price with respect to the Securities to be called for redemption in
accordance with Article III as provided in the Indenture), except payments and
distributions made by the Trustee as permitted by the first or second paragraph
of Section 12.5, if:

                  (i) a default in the payment of principal, premium, interest,
         rent or other obligations due on any Senior Indebtedness occurs and is
         continuing (or, in the case of Senior Indebtedness for which there is a
         period of grace, in the event of such a default that continues beyond
         the period of grace, if any, specified in the instrument or lease
         evidencing such Senior Indebtedness), unless and until such default
         shall have been cured or waived or shall have ceased to exist; or

                  (ii) a default, other than a payment default, on a Designated
         Senior Indebtedness occurs and is continuing that then permits holders
         of such Designated Senior Indebtedness to accelerate its maturity and
         the Trustee receives a notice of the default (a "Payment Blockage
         Notice") from a Representative or the Company.

         If the Trustee receives any Payment Blockage Notice pursuant to clause
(ii) above, no subsequent Payment Blockage Notice shall be effective for
purposes of this Section unless and until (A) at least 365 days shall have
elapsed since the initial effectiveness of the immediately prior Payment
Blockage Notice, and (B) all scheduled payments of principal, premium, if any,
and interest on the Securities that have come due have been paid in full in
cash. No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice.

                                       32

         The Company may and shall resume payments on and distributions in
respect of the Securities upon the earlier of:

         (1)      the date upon which the default is cured or waived or ceases
to exist, or

         (2) in the case of a default referred to in clause (ii) above, 179 days
pass after notice is received if the maturity of such Designated Senior
Indebtedness has not been accelerated, unless this Article XII otherwise
prohibits the payment or distribution at the time of such payment or
distribution.

         Upon any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or liquidation or reorganization of
the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become due upon all
Senior Indebtedness shall first be paid in full in cash or other payment
satisfactory to the holders of such Senior Indebtedness, or payment thereof in
accordance with its terms provided for in cash or other payment satisfactory to
the holders of such Senior Indebtedness, before any payment is made on account
of the principal of, premium, if any, or interest on the Securities (except
payments made pursuant to Article VI from monies deposited with the Trustee
pursuant thereto prior to commencement of proceedings for such dissolution,
winding-up, liquidation or reorganization); and upon any such dissolution or
winding-up or liquidation or reorganization of the Company or bankruptcy,
insolvency, receivership or other proceeding, any payment by the Company, or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the Holders of the Securities or the Trustee
would be entitled, except for the provision of this Article XII, shall (except
as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or distribution,
or by the Holders of the Securities or by the Trustee under this Indenture if
received by them or it, directly to the holders of Senior Indebtedness (pro rata
to such holders on the basis of the respective amounts of Senior Indebtedness
held by such holders, or as otherwise required by law or a court order) or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any Senior Indebtedness
may have been issued, as their respective interests may appear, to the extent
necessary to pay all Senior Indebtedness in full, in cash or other payment
satisfactory to the holders of such Senior Indebtedness, after giving effect to
any concurrent payment or distribution to or for the holders of Senior
Indebtedness, before any payment or distribution or provision therefor is made
to the Holders of the Securities or to the Trustee.

         For purposes of this Article XII, the words, "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article XII with respect
to the Securities to the payment of all Senior Indebtedness which may at the
time be outstanding; provided that (i) the Senior Indebtedness is assumed by the
new corporation, if any, resulting from any reorganization or readjustment, and
(ii) the rights of the holders of Senior Indebtedness (other than leases which
are not assumed by the Company or the new corporation, as the case may be) are
not, without the consent of such holders, altered by such reorganization or
readjustment. The consolidation of the Company with, or the merger of the
Company into, another corporation or the liquidation or dissolution of the
Company following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another corporation upon the terms and
conditions provided for in Article V shall not be deemed a dissolution,
winding-up, liquidation or reorganization for the purposes of this Section 12.2
if such other corporation shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions stated in Article V.

         In the event of the acceleration of the Securities because of an Event
of Default, no payment or distribution shall be made to the Trustee or any
Holder of Securities in respect of the principal of, premium, if any, or
interest on the Securities (including, but not limited to, the redemption price
with respect to the Securities called for redemption in accordance with Article
3 as provided in the Indenture), except payments and distributions made by the
Trustee as permitted by the first or second paragraph of Section 12.5, until all
Senior Indebtedness has been paid in full in cash or other payment satisfactory
to the holders of Senior Indebtedness or such acceleration is rescinded in
accordance with the terms of this Indenture. If payment of the Securities is
accelerated because of an Event of Default, the Company shall promptly notify
holders of Senior Indebtedness of the acceleration at the address set forth in
the notice from the Agent (or successor agent) to the Trustee as being the
address to which the Trustee should send its notice pursuant to this Section
12.2, unless there are no payment obligations of the Company thereunder and all
obligations thereunder to extend credit have been terminated or expired.

         In the event that, notwithstanding the foregoing provisions, any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (including, without limitation, by way
of setoff or otherwise), prohibited by the foregoing, shall be received by the
Trustee or the Holders of the Securities before all Senior Indebtedness is paid
in full in cash or other payment satisfactory to the holders of such Senior
Indebtedness, or provision is made for such payment thereof in accordance with
its terms in cash or other payment satisfactory to the holders of such Senior
Indebtedness, such payment or distribution shall be held in trust for the
benefit of and shall be paid over or delivered to the holders of Senior
Indebtedness or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing any
Senior Indebtedness may have been issued, as their respective interests may
appear, as calculated by the Company, for application to the payment of all
Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior
Indebtedness in full in cash or other payment satisfactory to the holders of
such Senior Indebtedness, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Indebtedness.

         Nothing in this Section 12.2 shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 7.7. This Section 12.2 shall be subject
to the further provisions of Section 12.5.

Section 12.3      Subrogation of Securities.

         Subject to the payment in full of all Senior Indebtedness, the rights
of the Holders of the Securities shall be subrogated to the extent of the
payments or distributions made to the holders of such Senior Indebtedness
pursuant to the provisions of this Article XII (equally and ratably with the
holders of all indebtedness of the Company which by its express terms is
subordinated to other indebtedness of the Company to substantially the same
extent as the Securities are subordinated and is entitled to like rights of
subrogation) to the rights of the holders of Senior Indebtedness to receive
payments or distributions of cash, property or securities of the Company
applicable to the Senior Indebtedness until the principal, premium, if any, and
interest on the Securities shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of the Senior
Indebtedness of any cash, property or securities to which the Holders of the
Securities or the Trustee would be entitled except for the provisions of this
Article XII, and no payment over pursuant to the provisions of this Article XII,
to or for the benefit of the holders of Senior Indebtedness by Holders of the
Securities or the Trustee, shall, as between the Company, its creditors other
than holders of Senior Indebtedness, and the Holders of the Securities, be
deemed to be a payment by the Company to or on account of the Senior
Indebtedness; and no payments or distributions of cash, property or securities
to or for the benefit of the Holders of the Securities pursuant to the
subrogation provisions of this Article XII, which would otherwise have been paid
to the holders of Senior Indebtedness shall be deemed to be a payment by the
Company to or for the account of the Securities. It is understood that the
provisions of this Article XII are and are intended solely for the purposes of
defining the relative rights of the Holders of the Securities, on the one hand,
and the holders of the Senior Indebtedness, on the other hand.

         Nothing contained in this Article XII or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Indebtedness, and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders of the Securities the principal of (and premium, if any)
and interest on the Securities as and when the same shall become due and payable
in accordance with their terms, or is intended to or shall affect the relative
rights of the Holders of the Securities and creditors of the Company other than
the holders of the Senior Indebtedness, nor shall anything herein or therein
prevent the Trustee or the Holder of any Security from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture, subject
to the rights, if any, under this Article XII of the holders of Senior
Indebtedness in respect of cash, property or securities of the Company received
upon the exercise of any such remedy.

         Upon any payment or distribution of assets of the Company referred to
in this Article XII, the Trustee, subject to the provisions of Section 7.1, and
the Holders of the Securities shall be entitled to rely upon any order or decree
made by any court of competent jurisdiction in which such bankruptcy,
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidating trustee,
agent or other person making such payment or distribution, delivered to the
Trustee or to the Holders of the Securities, for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon and all other facts pertinent thereto or to this Article XII.

Section 12.4      Authorization to Effect Subordination.

         Each Holder of a Security by the holder's acceptance thereof authorizes
and directs the Trustee on the holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article XII and appoints the Trustee to act as the holder's attorney-in-fact for
any and all such purposes. If the Trustee does not file a proper proof of claim
or proof of debt in the form required in any proceeding referred to in Section
6.3 hereof at least 30 days before the expiration of the time to file such
claim, the holders of any Senior Indebtedness or their representatives are
hereby authorized to file an appropriate claim for and on behalf of the Holders
of the Securities.

Section 12.5      Notice to Trustee.

         The Company shall give prompt written notice in the form of an
Officers' Certificate to a Responsible Officer of the Trustee and to any paying
agent of any fact known to the Company which would prohibit the making of any
payment of monies to or by the Trustee or any paying agent in respect of the
Securities pursuant to the provisions of this Article XII. Notwithstanding the
provisions of this Article XII or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts which
would prohibit the making of any payment of monies to or by the Trustee in
respect of the Securities pursuant to the provisions of this Article XII, unless
and until a Responsible Officer of the Trustee shall have received written
notice thereof at the Corporate Trust Office from the Company (in the form of an
Officers' Certificate) or a Representative or a holder or holders of Senior
Indebtedness or from any trustee thereof; and before the receipt of any such
written notice, the Trustee, subject to the provisions of Section 7.1, shall be
entitled in all respects to assume that no such facts exist; provided that if on
a date not fewer than two Business Days prior to the date upon which by the
terms hereof any such monies may become payable for any purpose (including,
without limitation, the payment of the principal of, or premium, if any, or
interest on any Security) the Trustee shall not have received, with respect to
such monies, the notice provided for in this Section 12.5, then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such monies and to apply the same to the purpose for which
they were received, and shall not be affected by any notice to the contrary
which may be received by it on or after such prior date.

         Notwithstanding anything in this Article XII to the contrary, nothing
shall prevent any payment by the Trustee to the Holders of monies deposited with
it pursuant to Section 8.1, and any such payment shall not be subject to the
provisions of Section 12.1 or 12.2.

         The Trustee, subject to the provisions of Section 7.1, shall be
entitled to rely on the delivery to it of a written notice by a Representative
or a person representing himself to be a holder of Senior Indebtedness (or a
trustee on behalf of such holder) to establish that such notice has been given
by a Representative or a holder of Senior Indebtedness or a trustee on behalf of
any such holder or holders. In the event that the Trustee determines in good
faith that further evidence is required with respect to the right of any person
as a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article XII, the Trustee may request such person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such person, the extent to which such person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such person under this Article XII, and if such
evidence is not furnished the Trustee may defer any payment to such person
pending judicial determination as to the right of such person to receive such
payment.

Section 12.6      Trustee's Relation to Senior Indebtedness.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XII in respect of any Senior Indebtedness at
any time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in Section 7.11 or elsewhere in this Indenture shall
deprive the Trustee of any of its rights as such holder.

         With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article XII, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and, subject to the
provisions of Section 7.1, the Trustee shall not be liable to any holder of
Senior Indebtedness if it shall pay over or deliver to Holders of Securities,
the Company or any other person money or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article XII or otherwise.

Section 12.7      No Impairment of Subordination.

         No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof which any such holder may have or
otherwise be charged with.

Section 12.8      Article Applicable to Paying Agents.

         If at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article shall (unless the context otherwise requires) be construed
as extending to and including such Paying Agent within its meaning as fully for
all intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; provided, however, that the first
paragraph of Section 12.5 shall not apply to the Company or any Affiliate of the
Company if it or such Affiliate acts as Paying Agent.

Section 12.9      Senior Indebtedness Entitled to Rely.

         The holders of Senior Indebtedness (including, without limitation,
Designated Senior Indebtedness) shall have the right to rely upon this Article
XII, and no amendment or modification of the provisions contained herein shall
diminish the rights of such holders unless such holders shall have agreed in
writing thereto.

     provisions.

     relating to the subject matter hereof and replaces all other understandings

     amended or modified in any way except by an agreement in writing signed by
     duly authorized representatives of the parties.
