                                                Authorized Signatory

         If the forms and terms of the Securities of the series and any
related coupons have been established in or pursuant to one or more Officers'
Certificates as permitted by Section 2.01 and 2.02, in authenticating such
Securities and accepting the additional responsibilities under this Indenture
in relating to such Securities the Trustee shall be entitled to receive, and
(subject to Section 7.01) shall be fully protected in relying upon an Opinion
of Counsel to the effect that:

         (a)      the form and terms of such Securities and coupons, if any,
have been duly authorized and established pursuant to Sections 2.01 and 2.02
and comply with this Indenture, and

         (b)      such Securities, when authenticated and delivered by the
Trustee and issued by the Company, and such coupons, if any, when issued by
the Company, in the manner and subject to any conditions specified in such
Opinion of Counsel, will constitute valid and legally binding obligations of
the Company, enforceable in accordance with their terms, subject to customary
exceptions, provided, however, that, with respect to Securities of a series
subject to a Periodic Offering, the Trustee shall be entitled to receive such
Opinion of Counsel only once at or prior to the time of the first
authentication of Securities of such series and that the Opinion of Counsel
above may state:

                           (x)      that the forms of such Securities have
been, and the terms of such Securities (when established in accordance with
such procedures as may be specified from time to time in a Company Order, all
as contemplated by and in accordance with a Board Resolution or any Officers'
Certificate pursuant to Section 2.01, as the case may be) will have been,
duly authorized by the Company and established in conformity with the
provisions of this Indenture;

                           (y)      that such Securities, together with the
coupons, if any, appertaining thereto, when (1) executed by the Company, (2)
completed, authenticated and

                                       12

<PAGE>

delivered by the Trustee in accordance with this Indenture, and (3) issued by
the Company in the manner and subject to any conditions specified in such
Opinion of Counsel, will constitute valid and legally binding obligations of
the Company, enforceable in accordance with their terms, subject to customary
exceptions; and

                           (z)      that all laws and requirements in respect
of the execution and delivery by the Company of such Securities have been

         (c)      With respect to Securities of a series subject to a
Periodic Offering, the Trustee may conclusively rely, as to the authorization
by the Company of any of such Securities, the form and terms thereof and the
legality, validity, binding effect and enforceability thereof, upon the
Opinion of Counsel and other documents delivered pursuant to Section 2.01 and
this Section, as applicable, at or prior to the time of the first
authentication of Securities of such series unless and until it has received
written notification that such opinion or other documents have been
superseded or revoked. In connection with the authentication and delivery of
Securities of a series subject to a Periodic Offering, the Trustee shall be
entitled to assume that the Company's instructions to authenticate and
deliver such Securities do not violate any rules, regulations or orders of
any governmental agency or commission having jurisdiction over the Company.

                  The Trustee shall have the right to decline to authenticate
and deliver any Securities under this Section if the Trustee, being advised
by counsel, determines that such action may not lawfully be taken or if the
Trustee in good faith shall determine that such action would expose the
Trustee to personal liability to existing Holders.

provisions of this Indenture that relate to such Agent. The Company shall
notify the Trustee of the name and address of any such Agent. If the Company
fails to maintain a Registrar or Paying Agent, or the Company fails to
maintain

                                       13

<PAGE>

an agent for service of notices, process and demands, or the Company fails to
give the foregoing notice, the Trustee shall act as such.

         The Company initially appoints the Trustee to be the Registrar,
Paying Agent and agent for services of notices and demands.

         Section 2.04.  PAYING AGENT TO HOLD MONEY IN TRUST.

         Each Paying Agent shall hold in trust for the benefit of
Securityholders or the Trustee all money held by the Paying Agent for the
payment of principal of or any interest or Additional Amounts on the
Securities, and shall notify the Trustee of any default by the Company (or
any other obligor on the Securities) in making any such payment. If the
Company or a Subsidiary acts as Paying Agent, it shall on or before each due
date of the principal of or any interest or Additional Amounts on any
Securities segregate the money and hold it as a separate trust fund. The
Company at any time may require a Paying Agent to pay all money held by it to
the Trustee and the Trustee may at any time during the continuance of any
payment default, upon written request to a Paying Agent, require such Paying
Agent to pay to the Trustee all sums so held in trust by such Paying Agent.
Upon doing so the Paying Agent shall have no further liability for the money.

         Section 2.05.  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 Holders of Registered Securities. If the Trustee is not the Registrar, the
Company shall furnish to the Trustee from information in the possession or
control of the Company (a) on or before each interest payment date, as of the
relevant record date, for any series of Securities, (b) pursuant to the form
of Security for each series of non-interest bearing Securities and (c) 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, provided that if the provisions of (a) or (b)
do not provide for the furnishing of such information at stated intervals of
not more than six months, at least as frequently as semiannually, not later
than May 15 and November 15 of each year.

         Section 2.06.  TRANSFER, REGISTRATION AND EXCHANGE.

         When a Registered Security is presented at an office or agency
maintained for that series pursuant to Section 4.02 in proper form for
registration of transfer with a request to register a transfer, the Registrar
or co-Registrar at that office shall register the transfer as requested.

         At the option of the Securityholder, Registered Securities of any
series may be exchanged upon surrender to the Registrar or a co-Registrar for
Registered Securities of the same series of like aggregate principal amount,
stated maturity and tenor and of other authorized denominations upon
surrender at any office or agency maintained for that series pursuant to
Section 4.02.

                                       14

<PAGE>

         If so provided with respect to Securities of a series, at the option
of the Holder, Bearer Securities of any such series may be exchanged for
Registered Securities of the same series containing identical terms and
provisions, of any authorized denominations and aggregate principal amount,
upon surrender of the Bearer Securities to be exchanged at any office or
agency maintained for that series pursuant to Section 4.02, with all
unmatured coupons and all matured coupons appertaining thereto in default.
If the Holder of a Bearer Security is unable to produce any such unmatured
coupon or coupons or matured coupon or coupons in default, such exchange may
be effected if the Bearer Securities are accompanied by payment in funds
acceptable to the Company and the Trustee in an amount equal to the face
amount of such missing coupon or coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there is
furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent for that series harmless. If thereafter the
Holder of such Security shall surrender to any Paying Agent for that series
any such missing coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that except as otherwise provided in Section 4.02,
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any
series is surrendered at any such office or agency maintained for that series
pursuant to Section 4.02 in exchange for a Registered Security of the same
series and like tenor after the close of business at such office or agency on
any record date for the payment of interest and any Additional Amounts
thereon and before the opening of business at such office or agency on the
relevant payment date therefor, such Bearer Security shall be surrendered
without the coupon relating to such payment date or proposed date of payment,
as the case may be (or if such coupon is so surrendered with such Bearer
Security, such coupon shall be returned to the person so surrendering the
Bearer Security), and interest will not be payable on such payment date or
proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable
only to the Holder of such coupon when due in accordance with the provisions
of this Indenture.

         Every Security presented or surrendered for registration of transfer
or exchange shall (if so required by the Company or the Registrar or
co-Registrar) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Registrar duly executed
by the Holder thereof or his attorney duly authorized in writing. To permit
transfers and exchanges, the Company shall execute and the Trustee shall
authenticate Securities at the Registrar's or co-Registrar's request.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 2.01, any global Security shall be exchangeable only
if (i) the Securities Depository is at any time unwilling, unable or
ineligible to continue as Securities Depository and a successor Depository is
not appointed by the Company within 90 days of the date the Company and the
Trustee is so informed in writing, (ii) the Company executes and delivers to
the Trustee a Company Order to the effect that such global Security shall be
so exchangeable, or (iii) an Event

                                       15

<PAGE>

of Default has occurred and is continuing with respect to the Securities. If
the beneficial owners of interests in a global Security are entitled to
exchange such interests for Securities of such series and of like tenor and
principal amount of any authorized form and denomination, as specified as
contemplated by Section 2.01, then without unnecessary delay but in any event
not later than the earliest date on which such interests may be so exchanged,
Company shall deliver to the Trustee definitive Securities of that series in
aggregate principal amount equal to the principal amount of such global
Security, executed by the Company. On or after the earliest date on which
such interests may be so exchanged, such global Securities shall be
surrendered from time to time by the U.S. Depository or such other Depository
as shall be specified in the Company Order with respect thereto, and in
accordance with instructions given to the Trustee and the U.S. Depository or
such Depository, as the case may be, which instructions shall be in writing
but need not be accompanied by an Officers' Certificate of the Company or an
Opinion of Counsel, as shall be specified in the Company Order with respect
thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities of the same series
without charge. The Trustee shall authenticate and make available for
delivery, in exchange for each portion of such surrendered global Security, a
like aggregate principal amount of definitive Securities of the same series
of authorized denominations and of like tenor as the portion of such global
Security to be exchanged which shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by
the beneficial owner thereof (unless the Securities of the series are not
issuable both as Bearer Securities and as Registered Securities, in which
case the definitive Securities exchanged for the global Security shall be
issuable only in the form in which the Securities are issuable, as specified
as contemplated by Section 2.01); provided, however, that no such exchanges
may occur during a period beginning at the opening of business 15 days before
any selection of Securities of that series to be redeemed and ending on the
relevant Redemption Date; and provided, further, that (unless otherwise
specified as contemplated by Section 2.01) no Bearer Security delivered in
exchange for a portion of a global Security shall be mailed or otherwise
delivered to any location in the United States. Promptly following any such
exchange in part, such global Security shall be returned by the Trustee to
such depository or the U.S. Depository referred to above in accordance with
the instructions of the Company referred to above. If a Registered Security
is issued in exchange for any portion of a global Security after the close of
business at the office or agency where such exchange occurs on any record
date for the payment of interest or any Additional Amounts thereon, and
before the opening of business at such office or agency on the relevant
payment date therefor, interest and any Additional Amounts in respect of such
Registered Security will not be payable on such payment date, but will be
payable on such payment date only to the Person to whom interest or any
Additional Amounts in respect of such portion of such global Security is
payable in accordance with the provisions of this Indenture.

         No service charge shall be made for any registration of transfer or
exchange, or redemption of Securities, but the Company may require payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of

                                       16

<PAGE>

transfer or exchange of Securities, other than exchanges pursuant to Section
2.09, 3.07 or 9.05 not involving any transfer.

         The Company and the Trustee shall not be required (a) to issue,
register the transfer of, or exchange any Securities of any series for a
period of 15 days next preceding the day of any selection of Securities of
such series to be redeemed pursuant to Section 3.03, or (b) to register the
transfer of or exchange any Securities of any series selected, called or
being called for redemption in whole or in part except, in the case of any
Registered Security to be redeemed in part, the portion thereof not so to be
redeemed or (c) to exchange any Bearer Security so selected for redemption
except, to the extent provided with respect to Securities of a series, that
such a Bearer Security may be exchanged for a Registered Security of that
series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent
with the provisions of this Indenture.

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

         Section 2.07.  REPLACEMENT SECURITIES2.08

         If the Holder of a mutilated or defaced Security or a Security with
a mutilated or defaced coupon appertaining to it surrenders such Security to
the Trustee or if the Holder of a Security presents evidence to the
satisfaction of the Company and the Trustee that the Security has been lost,
destroyed or wrongfully taken or that a coupon has been lost, stolen or
wrongfully taken and surrenders the Security to which such coupon appertains
with all appurtenant coupons not so lost, stolen or wrongfully taken, the
Company shall issue and the Trustee shall authenticate a replacement Security
of the same series and of like tenor, with coupons corresponding to the
coupons, if any, appertaining to the surrendered Security. In case any such
mutilated, defaced, lost, destroyed or wrongfully taken Security or coupon
has or is about to become due and payable, the Company may pay the Security
or coupon instead of issuing a new Security or coupon; provided, however,
that payment of principal of and any interest on and Additional Amounts with
respect to Bearer Securities shall, except as otherwise provided in Section
4.02, be payable only at an office or agency located outside the United
States and, unless otherwise specified as contemplated by Section 2.01, any
interest on Bearer Securities shall be payable only upon presentation and
surrender of the coupons appertaining thereto. If required by the Trustee or
the Company, an indemnity bond must be provided which is sufficient in the
judgment of the Company and the Trustee to protect the Company and the
Trustee or any Agent from any loss which any of them may suffer if a Security
is replaced. The Company and the Trustee may charge the Holder for their fees
and expenses in replacing a Security and for payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto.

                                       17

<PAGE>

         Every replacement Security of any series, with its coupons, if any,
is an additional obligation of the Company and shall be entitled to all of
the benefits of this Indenture equally and proportionately with any and all
other Securities of that series and their coupons, if any, duly issued under
this Indenture.

         Section 2.08.  OUTSTANDING SECURITIES.

         Securities Outstanding at any time are all Securities authenticated
by the Trustee except for those canceled by it and those described in this
Section. A Security does not cease to be Outstanding because the Company or
one of its Affiliates holds the Security except as provided in Section 13.06.

         If a Security is replaced pursuant to Section 2.07, it ceases to be
Outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

         If the Paying Agent holds on a Redemption Date or maturity date
money sufficient to pay Securities payable on that date, then on and after
that date such Securities cease to be Outstanding and interest on them ceases
to accrue, provided that, if such Securities are to be redeemed, notice of
such redemption has been duly given pursuant to this Indenture or provision
therefor satisfactory to the Trustee has been made.

         If the Company is deemed to be discharged from its obligations with
respect to the Securities of any series pursuant to Section 8.01 or 8.02, the
Securities of such series shall cease to be Outstanding.

         In determining whether the Holders of the requisite principal amount
of Outstanding Securities of any or all series have given any request,
demand, authorization, direction, notice, consent or waiver hereunder, the
principal amount of an Original Issue 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 6.01, as adjusted pursuant to Section 13.12 if applicable.

         Section 2.09.  TEMPORARY SECURITIES.

         Until definitive Securities are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Securities. Temporary
Securities and, if Bearer Securities, temporary coupons shall be
substantially in the form of definitive Securities and, if Bearer Securities,
definitive coupons but may have variations in form that the Company considers
appropriate for temporary Securities. In the case of Bearer Securities of any
series, such temporary Securities may be in global form representing all of
the Outstanding Bearer Securities of such series. Except in the case of
temporary Securities in global form (which shall be

                                       18

<PAGE>

exchanged in accordance with the provisions thereof), without unreasonable
delay, the Company shall prepare definitive Securities (accompanied by any
unmatured coupons pertaining thereto) of like tenor as the temporary
Securities.

         After the preparation of definitive Securities of a series, the
temporary Securities of such series shall be exchangeable upon request for
definitive Securities of such series containing identical terms and
provisions upon surrender of the temporary Securities of such series at an
office or agency of the Company maintained for such purpose pursuant to
Section 4.02, without charge to the Holder. Upon surrender for cancellation
of any one or more temporary Securities of any series (accompanied by any
unmatured coupons appertaining thereto), the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same
series containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided pursuant to Section 2.01,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the
conditions set forth therein. Unless otherwise specified as contemplated by
Section 2.01 with respect to a temporary global Security, until so exchanged
the temporary Securities of any series shall in all respects be entitled to
the same benefits under this Indenture as definitive Securities of such
series.

         Section 2.10.  SECURITIES IN GLOBAL FORM.

         If Securities of a series are issuable in global form, any such
Security may provide that it shall represent the aggregate amount of
Outstanding Securities from time to time endorsed thereon and may also
provide that the aggregate amount of Outstanding Securities represented
thereby may from time to time be reduced to reflect exchanges. Any
endorsement of a Security in global form to reflect the amount, or any
increase or decrease in the amount, or changes in the rights of Holders, of
Outstanding Securities represented thereby shall be made in such manner and
by such Person or Persons as shall be specified therein.

         Section 2.11.  CANCELLATION.

         The Company at any time may deliver Securities or coupons to the
Trustee for cancellation. The Registrar and Paying Agent shall forward to the
Trustee any Securities surrendered to them for transfer, exchange or payment
and all coupons surrendered for payment. The Trustee shall cancel all
Securities surrendered for transfer, exchange, payment or cancellation and
all coupons surrendered for payment and return such canceled Securities to
the Company upon Company Order, provided, however, that the Trustee shall
dispose of canceled Securities in accordance with its procedures for the
disposition of canceled securities in effect as of the date of such
disposition unless the Company directs their return to the Company. The
Company may not issue new Securities to replace Securities that it has paid
or delivered to the Trustee for cancellation.

<PAGE>

         Section 2.12.  DEFAULTED INTEREST.

         If the Company defaults in a payment of interest or any Additional
Amounts on any series of Registered Securities, the Company shall pay the
defaulted interest and any Additional Amounts to Persons who are Holders of
Registered Securities of such series in any lawful manner.  The Company may
also pay the defaulted interest to the persons who are Security holders on a
subsequent special record date in the following manner. The Company shall fix
the special record date (which shall be between 10 and 30 days before the
payment date) for the payment of such defaulted interest and any Additional
Amounts on such Securities and the payment date for such defaulted interest.
At least 15 days before the special record date, the Company shall mail each
Holder of Registered Securities, with a copy to the Trustee, a notice that
states the special record date, the payment date and the amount of defaulted
interest and any Additional Amounts to be paid, provided the Company has made
arrangements satisfactory to the Trustee for payment of the aggregate amount
to be paid on such payment date. On such payment date the Trustee shall pay
out of funds provided by the Company such defaulted interest and any
Additional Amounts. In case a Bearer Security of any series is surrendered at
the office or agency of the Company maintained pursuant to Section 4.02 in a
Place of Payment for such series in exchange for a Registered Security of
such series after the close of business at such office or agency on any
special record date and before the opening of business at such office or
agency on the related proposed date for payment of defaulted interest and any
Additional Amounts, such Bearer Security shall be surrendered without the
coupon relating to such proposed date of payment and defaulted interest and
any Additional Amounts will not be payable on such proposed date of payment
in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such coupon on or after
such payment date in accordance with the provisions of this Indenture. The
Company may pay defaulted interest and any Additional Amounts in any other
lawful manner.

         Section 2.13.  PERSONS DEEMED OWNERS.

         Prior to due presentment of a Registered Security for registration
of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such Registered Security is
registered as the absolute owner of such Registered Security for the purpose
of receiving payments of principal of and (subject to Sections 2.06 and 4.01)
interest on and Additional Amounts with respect to such Registered Security
and for all other purposes whatsoever, whether or not such Registered
Security shall be overdue, and neither the Company, the Trustee nor any agent
of the Company or the Trustee shall be affected by notice to the contrary.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer Security and the bearer of any coupon as
the absolute owner of such Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon shall be overdue, and neither

                                       20

<PAGE>

the Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         Section 2.14.  CUSIP NUMBERS.

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

                                  ARTICLE THREE
                                    REDEMPTION

         Section 3.01.  APPLICABILITY OF ARTICLE.

         This Article shall apply to the Securities of each series, if any,
that by their terms are subject to redemption at the option of the Company or
pursuant to the operation of a sinking fund or otherwise are required to be
redeemed pursuant to the terms of the Securities. If the terms of any
Security shall conflict with any provision of this Article, the terms of such
Security shall govern.

         Section 3.02.  NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution. If the Company wants to redeem Securities of
any series in whole or in part pursuant to the terms of the Securities of
that series, the Company shall notify the Trustee of the Redemption Date
therefor and the principal amount and other terms and provisions of the
Securities to be redeemed. Each such notice shall be accompanied by an
Officers' Certificate of the Company stating that any conditions to such
redemption as provided in such Security and in this Article have been
complied with. If the Company elects to redeem less than all of the
Securities of a series with the same terms and provisions, the Company shall
notify the Trustee of such Redemption Date and of the principal amount of
such Securities to be redeemed and shall deliver to the Trustee such
documentation and records as shall enable the Trustee to select the
Securities to be redeemed pursuant to Section 3.03.

         If Securities of any series by their terms are redeemable pursuant
to the operation of a sinking fund or pursuant to another mandatory
redemption provision of the Securities, the Company shall notify the Trustee
by an Officers' Certificate of the amount of the next sinking fund payment or
amount required to satisfy such mandatory redemption payment and the portion

                                       21

<PAGE>

of such payment which is to be satisfied by delivering and crediting
Securities of the same series pursuant to Section 3.06.

         If the Company wants to reduce, pursuant to the terms of such
Securities, the principal amount of Securities to be redeemed, it shall
notify the Trustee by Officers' Certificate of the amount of the reduction
and the basis for it. If the Company wants to credit against any such
redemption Securities of the same series it has not previously delivered to
the Trustee for cancellation, it shall deliver the Securities with such
Officers' Certificate.

         The Company shall give each notice and an Officers' Certificate
provided for in this Section at least 45 days before the applicable
Redemption Date (unless shorter notice is satisfactory to the Trustee or a
shorter or longer notice is required by the applicable Security).

         Section 3.03.  SELECTION OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of a series with the same terms and
provisions are to be redeemed, the Trustee shall select the Securities to be
redeemed by a method the Trustee considers fair and appropriate. The Trustee
shall make the selection from such Securities Outstanding not previously
called for redemption. The Trustee may select for redemption portions of the
principal of Registered Securities of such series that have denominations
larger than the minimum authorized denominations for Registered Securities of
that series. Securities and portions thereof the Trustee selects shall be in
amounts equal to the smallest authorized denominations or an integral
multiple thereof. Provisions of this Indenture that apply to Securities
called for redemption also apply to portions of Registered Securities called
for redemption.

         The Trustee shall promptly notify the Company and the Registrar (if
other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

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

         Section 3.04.  NOTICE OF REDEMPTION.

         At least 30 days but not more than 60 days before a Redemption Date
(unless a shorter or longer period is specified in the Securities to be
redeemed), the Company shall give notice of such redemption to the Holders of
the Securities to be redeemed as a whole or in part, with a copy to the
Trustee, with respect to Registered Securities, by mailing a notice of such
redemption by first-class mail to each Holder of Registered Securities to be
redeemed and, with respect to

                                       22

<PAGE>

Bearer Securities, by publishing in an Authorized Newspaper notice of such
redemption on two separate days.

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

                  (1)      the Redemption Date;

                  (2)      the Redemption Price, including premium, if any,
accrued interest and Additional Amounts, if any;

                  (3)      if less than all Securities of a series
Outstanding are to be redeemed, the identification (and, if any Security is
to be redeemed in part, the principal amount) of the particular Securities to
be redeemed;

                  (4)      the name or names and address or addresses of the
Paying Agent;

                  (5)      that Securities called for redemption must be
surrendered to the Paying Agent to collect the Redemption Price, including
premium, if any, accrued interest and Additional Amounts, if any;

                  (6)      that interest on Securities called for redemption
ceases to accrue on and after the Redemption Date;

                  (7)      that the redemption is pursuant to a sinking fund,
if such is the case;

                  (8)      the Place or Places of Payment where such
Securities are to be surrendered for payment for the Redemption Price;

                  (9)      the CUSIP number, if any, of the Securities; and

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

         At the Company's request delivered to the Trustee at least 15 days
prior to the date proposed for the giving of such notice, the Trustee shall
give the notice of redemption in the Company's name and at the Company's
expense.

         Section 3.05.  EFFECT OF NOTICE OF REDEMPTION.

         Once notice of redemption is given pursuant to Section 3.04,
Securities called for redemption shall become due and payable on the
Redemption Date therefor and at the applicable Redemption Price.  Any failure
to mail notice of redemption or any defect therein shall not affect the
redemption of any other Securities called for redemption.  Upon surrender to
the Paying Agent for such Securities of such Securities together with all
unmatured coupons, if any,

                                       23

<PAGE>

appertaining thereto, such Securities shall be paid at the applicable
Redemption Price, plus accrued interest to the Redemption Date and any
Additional Amounts payable with respect thereto; provided, however, that any
regular payment of interest and any Additional Amounts payable with respect
thereto becoming due on the Redemption Date shall be payable, in the case of
Bearer Securities, to bearers of the coupons for such interest and Additional
Amounts upon surrender thereof and in the case of Registered Securities to
the Holders of such Securities in accordance with their terms.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date,
such Security may be paid after deducting from the Redemption Price an amount
equal to the face amount of all such missing coupons, or the surrender of
each missing coupon or coupons may be waived by the Company and the Trustee
if there shall be furnished to them such security or indemnity as they may
require to save each of them and any Paying Agent for such Security harmless.
If thereafter the Holder of such Security shall surrender to the Trustee or
any Paying Agent for such Security any such missing coupon in respect of
which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; provided, however, that
interest (and any Additional Amounts) represented by coupons shall be payable
only upon presentation and surrender of these coupons at an office or agency
located outside of the United States except as otherwise provided in Section
4.02.

         Section 3.06.  DEPOSIT OF REDEMPTION PRICE OR SECURITIES.

         By 10:00 a.m. New York City time, on or before the Redemption Date,
the Company shall deposit with the applicable Paying Agent (or if the Company
is its own Paying Agent, shall segregate and hold in trust) money sufficient
to pay the Redemption Price of and accrued interest and Additional Amounts,
if any, on all Securities to be redeemed on that date.

         If any Security by its terms permits any sinking fund payment
obligation to be satisfied by delivering and crediting Securities, the
Company shall deliver such Securities to the Trustee for crediting against
such payment obligation in accordance with the terms of such Securities and
this Indenture.

         Section 3.07.  SECURITIES REDEEMED IN PART.

         Upon surrender of a Security that is redeemed in part at any office
or agency maintained by the Company pursuant to Section 4.02, the Company
shall execute and Trustee shall authenticate for the Holder a new Security of
the same series equal in principal amount to the unredeemed portion of the
Security surrendered.

         If a Security in global form is surrendered upon redemption in part,
the Company shall execute, and the Trustee shall authenticate and deliver to
the U.S. Depository or other Depository for such Security in global form as
shall be specified in the Company Order to the Trustee with

                                       24

<PAGE>

respect thereto, without service charge, a new Security in global form in a
denomination equal to and in exchange for the unredeemed portion of the
principal of the Security in global form so surrendered.

                                  ARTICLE FOUR
                                   COVENANTS

         Section 4.01.  PAYMENT OF SECURITIES.

         The Company shall pay the principal of and any interest or
Additional Amounts, if any, and premium, if any, on the Securities of each
series on the dates and in the manner provided in the Securities, any coupons
appertaining thereto and this Indenture. At the Company's option, it can pay
any interest or Additional Amounts, if any, or premium, if any, on Registered
Securities of any series by mailing checks or drafts to the Holders of such
Securities at their addresses as shown in the Security Register. Any interest
due on and any Additional Amounts payable in respect of Bearer Securities on
or before their maturity, in respect of the principal of such a Security
shall be payable only upon presentation and surrender of the several coupons
for such interest installments as are evidenced thereby as they severally
mature.

         The Company shall pay interest on overdue principal of any Security
at the rate borne by such Security; it shall pay interest on overdue
installments of interest or Additional Amounts, if any, or premium, if any,
at the same rate to the extent lawful.

         In case a Bearer Security of any series is surrendered in exchange
for a Registered Security of such series after the close of business (at an
office or agency in a Place of Payment for such series) on any record date
established to determine the Person to whom interest or Additional Amounts
are payable on the next following interest payment date therefor and before
the opening of business (at such office or agency) on such interest payment
date, such Bearer Security shall be surrendered without the coupon relating
to such interest payment date and interest will not be payable on such
interest payment date in respect of the Registered Security issued in
exchange of such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

         Section 4.02.  MAINTENANCE OF OFFICE OR AGENCY.

         The Company shall maintain in each Place of Payment for any series
of Securities an office or agency where Securities of that series (but not
Bearer Securities, except as otherwise provided below, unless such Place of
Payment is located outside the United States) may be presented or surrendered
for payment, where Securities of that series may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture
may be served.

                                       25

<PAGE>

        If Securities of a series are issuable as Bearer Securities, the
Company shall maintain, subject to any laws or regulations applicable
thereto, an office or agency in a Place of Payment for such series which is
located outside the United States where Securities of such series and the
related coupons may be presented and surrendered for payment (including
payment of any Additional Amounts payable on Securities of such series);
provided, however, that if the Securities of such series are listed on The
International Stock Exchange of the United Kingdom and the Republic of
Ireland Limited or the Luxembourg Stock Exchange or any other stock exchange
located outside the United States and such stock exchange shall so require,
the Company will maintain a Paying Agent in London, Luxembourg or any other
city so required located outside the United States, as the case may be, so
long as the Securities of such series are listed on such exchange. The
Company will give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the
Company shall fail to maintain any such required office or agency or shall
fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, except that Bearer Securities of that series and the
related coupons may be presented and surrendered for payment (including
payment of any Additional Amounts payable on Bearer Securities of that
series) at the place specified for that purpose pursuant to Section 2.01.

         Except as otherwise provided in the form of Bearer Security of any
particular series pursuant to the provisions of this Indenture, no payment of
principal or interest or Additional Amounts on Bearer Securities shall be
made at any office or agency of the Company in the United States or by check
mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however,
payment of principal of and interest in U.S. dollars (including Additional
Amounts payable in respect thereof) on any Bearer Security may be made at the
office of the Paying Agent in the Borough of Manhattan, The City of New York,
New York, if (but only if) payment of the full amount of such principal,
interest or Additional Amounts at all offices outside the United States
maintained for that purpose by the Company in accordance with this Indenture
is illegal or effectively precluded by exchange controls or other similar
restrictions.

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

         Section 4.03.  MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it shall, on or before each due date of
the principal of, or interest or Additional

                                       26

<PAGE>

Amounts on, any of the Securities of that series, segregate and hold in trust
for the benefit of the Person entitled thereto a sum sufficient to pay the
principal or interest or Additional Amounts so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided,
and shall promptly notify the Trustee of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, by 10:00 a.m. New York City time, on or prior
to each due date of the principal of, or interest or Additional Amounts on,
any Securities of that series, deposit with any Paying Agent a sum sufficient
to pay the principal or interest and Additional Amounts so becoming due, such
sum to be held in trust for the benefit of the Persons entitled to such
principal, interest or Additional Amounts, and (unless such Paying Agent is
the Trustee) the Company shall promptly notify the Trustee of its action or
failure so to act.

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

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

                  (2)      give the Trustee notice of any Default by the
Company in the making of any payment of principal or interest or any
Additional Amounts on the Securities of that series; and

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

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

         Except as otherwise provided in the form of Securities of any
particular series pursuant to the provisions of this Indenture, any money
deposited with the Trustee or any Paying Agent, or then held by the Company,
in trust for the payment of the principal of or interest or any Additional
Amounts on any Security of any series and remaining unclaimed for one year
after such principal or interest has or Additional Amounts have become due
and payable shall be paid to the Company upon receipt of a Company Order to
that effect, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security or any coupon

                                       27

<PAGE>

appertaining thereto shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that
the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in
an Authorized Newspaper in each Place of Payment or to be mailed to Holders
of Registered Securities, or both, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30
days from the date of such publication or mailing nor shall it be later than
one year after such principal or interest or Additional Amount has become due
and payable, any unclaimed balance of such money then remaining shall be
repaid to the Company.

         Section 4.04.  SEC REPORTS.

         The Company shall file with 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 Securities Exchange Act of 1934, as amended. The Company also shall
comply with the other provisions of TIA Section 314(a).

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

         Section 4.05.  STATEMENT AS TO COMPLIANCE.

         (a)      The Company shall deliver to the Trustee, within 120 days
after the end of each fiscal year, commencing April 30, 2001 (no more than
one year after closing), a written statement, which need not comply with
Section 13.05 hereof, signed by a principal executive officer, principal
financial officer or principal accounting officer, stating, as to the signer
thereof, that

                  (1)      a review of the activities of the Company during
such year and of performance under this Indenture has been made under his
supervision, and

                  (2)      to the best of his knowledge, based on such
review, (a) the Company has fulfilled its obligations under this Indenture
throughout such year, or, if there has been a default in the fulfillment of
any such obligation, specifying each such default known to him and the nature
and status thereof, and (b) no event has occurred and is continuing which is,
or after notice or lapse of time or both would become, an Event of Default,
or, if such an event has occurred and is continuing, specifying each such
event known to him and the nature and status thereof.

                                       28

<PAGE>

         (b)      The Company shall deliver to the Trustee, as soon as
possible and in any event within ten days after the Company obtains knowledge
of the occurrence thereof, written notice of any Default and the action which
the Company proposes to take with respect thereto.

         Section 4.06.  LIMITATIONS ON LIENS ON STOCK OF RESTRICTED
SUBSIDIARIES.

         The Company will not, and will not permit any Restricted Subsidiary
to, issue, assume or guarantee any debt for money borrowed (hereafter in this
Section referred to as "Debt") secured by a mortgage, security interest,
pledge, lien or other encumbrance upon any shares of stock of any Restricted
Subsidiary (whether such shares of stock are now owned or hereafter acquired)
without in any such case effectively providing concurrently with the
issuance, assumption or guarantee of any such Debt that the Securities
(together with, if the Company shall so determine, any other indebtedness of
or guarantee by the Company ranking equally with the Securities and then
existing or thereafter created) shall be secured equally and ratably with
such Debt.

         Section 4.07.  LIMITATIONS ON ISSUE OR DISPOSITION OF STOCK OF
RESTRICTED SUBSIDIARIES.

         The Company will not, and will not permit any Restricted Subsidiary
to, issue, sell, assign, transfer or otherwise dispose of, directly or
indirectly, any of the Capital Stock (other than nonvoting preferred stock)
of any Restricted Subsidiary (except to the Company or to one or more
Restricted Subsidiaries or for the purpose of qualifying directors);
provided, however, that this covenant shall not apply if:

                  (1)      all or any part of such Capital Stock is sold,
assigned, transferred or otherwise disposed of in a transaction for
consideration which is at least equal to the fair value of such Capital
Stock, as determined by the Board of Directors (acting in good faith); or

                  (2)      the issuance, sale, assignment, transfer or other
disposition is required to comply with the order of a court or regulatory
authority of competent jurisdiction, other than an order issued at the
request of the Company or of one of its Restricted Subsidiaries.

         Section 4.08.  ADDITIONAL AMOUNTS.

         If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities, and to notify the Trustee in writing of
any such payment and the record date thereof.  Whenever in this Indenture
there is mentioned, in any context, the payment of the principal of or any
premium or interest on, or in respect of, any Security of any series or any
Coupon or the net proceeds received on the sale or exchange of any Security
of any series, such mention shall be deemed to include mention of the payment
of Additional Amounts provided by the terms of such series established hereby
or pursuant hereto to the extent that, in such context, Additional Amounts
are,

                                       29

<PAGE>

were or would be payable in respect thereof pursuant to such terms, and
express mention of the payment of Additional Amounts (if applicable) in any
provision hereof shall not be construed as excluding the payment of
Additional Amounts in those provisions hereof where such express mention is
not made.

         Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, if the Securities of a series provide
for the payment of Additional Amounts, at least 10 days prior to the first
interest payment date with respect to such series of Securities (or if the
Securities of such series shall not bear interest prior to maturity, the
first day on which a payment of principal is made), and at least 10 days
prior to each date of payment of principal or interest if there has been any
change with respect to the matters set forth in the below-mentioned Officers'
Certificate, the Company shall furnish to the Trustee and the principal
Paying Agent or Paying Agents, if other than the Trustee, an Officers'
Certificate instructing the Trustee and such Paying Agent or Paying Agents
whether such payment of principal of and premium, if any, or interest on the
Securities of such series shall be made to Holders of Securities of such
series or the Coupons appertaining thereto who are United States Aliens
without withholding for or on account of any tax, assessment or other
governmental charge described in the Securities of such series. If any such
withholding shall be required, then such Officers' Certificate shall specify
by country the amount, if any, required to be withheld on such payments to
such Holders of Securities or Coupons, and the Company agrees to pay to the
Trustee or such Paying Agent the Additional Amounts required by the terms of
such Securities. The Company covenants to indemnify the Trustee and any
Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them
in reliance on any Officers' Certificate furnished pursuant to this Section.

         Section 4.09.  WAIVER OF CERTAIN COVENANTS.

         The Company may omit in any particular instance, to comply with any
covenant or condition set forth in Sections 4.06 or 4.07, if before or after
the time for such compliance the Holders of at least a majority in principal
amount of all Outstanding Securities, and the Holders of at least a majority
in principal amount of the Outstanding Securities of each series to be
affected, shall either waive such compliance in such instance or generally
waive compliance with such covenant or condition, but no such waiver shall
extend to or affect such covenant or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any
such covenant or condition shall remain in full force and effect.

         Section 4.10.  INFORMATION REGARDING ORIGINAL ISSUE DISCOUNT.

         The Company shall provide to the Trustee on a timely basis such
information as the Trustee requires to enable the Trustee to prepare and file
any form required to be submitted by

                                       30

<PAGE>

the Company with the Internal Revenue Service and the Holders of Discount
Securities relating to original issue discount, including, without
limitation, Form 1099-OID or any successor form.

                     SUCCESSOR CORPORATION AND ASSUMPTION

         Section 5.01.  WHEN COMPANY MAY MERGE, ETC.

         The Company shall not consolidate with or merge into, or sell, lease
(for a term extending beyond the last stated maturity of the Securities then
Outstanding) or convey all or substantially all of its assets to, another
Person unless the successor or transferee Person expressly assumes by
supplemental indenture, in form satisfactory to the Trustee, all the
obligations of the Company with respect to the Securities and this Indenture,
and the Company or successor Corporation, as the case may be, (i) shall be a
Corporation organized under the laws of one of the states in the United
States and (ii) shall not, immediately after such consolidation or merger or
sale, lease or conveyance, be in default in the performance of any covenant
or condition with respect to the Securities or the Indenture. The Company
shall deliver to the Trustee an Officers' Certificate and an Opinion of
Counsel, each stating that such consolidation, merger or transfer and such
supplemental indenture comply with this Indenture. Thereafter all such
obligations of the predecessor corporation shall terminate.

         Section 5.02.  SUCCESSOR CORPORATION SUBSTITUTED.

         Upon any consolidation or merger, or any sale, lease or conveyance
of all or substantially all of the assets of the Company in accordance with
Section 5.01, the successor Corporation formed by such consolidation or into
which the Company is merged or to which such transfer is made shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under this Indenture with the same effect as if such successor
Corporation had been named as the Company herein.

         Section 5.03.  LIMITATION.

         Nothing in this Indenture shall be deemed to prevent or restrict:
(a) any consolidation or merger after the consummation of which the Company
would be the surviving or resulting entity or any conveyance or other
transfer or lease of any part of the properties of the Company which does not
constitute the entirety, or substantially the entirety, thereof; or (b) the
approval by the Company of, or the consent by the Company to, any
consolidation or merger to which any Restricted Subsidiary (or any other
subsidiary or affiliate of the Company) may be a party or any conveyance,
transfer or lease by any Subsidiary (or any such other subsidiary or
affiliate) of any of its assets.

                              DEFAULTS AND REMEDIES

         Section 6.01.  EVENTS OF DEFAULT.

         An "Event of Default" occurs with respect to the Securities of any
series upon:

         (a)      default in the payment of any installment of interest upon
or any Additional Amounts payable in respect of any of the Securities of such
series as and when the same shall become due and payable, and continuance of
such default for a period of 30 days; or

         (b)      default in the payment of all or any part of the principal
on any of the Securities of such series as and when the same shall become due
and payable either at maturity, upon redemption, by declaration or otherwise
(except the failure to make payment when due and payable if such failure
results solely from nonpayment by reason of mistake, oversight or transfer
difficulties and does not continue beyond 3 Business Days after the day on
which such payment is due and payable); or

         (c)      default in the payment of any sinking fund installment as
and when the same shall become due and payable by the terms of the Securities
of such series (except the failure to make payment when due and payable if
such failure results solely from nonpayment by reason of mistake, oversight
or transfer difficulties and does not continue beyond 3 Business Days after
the day on which such payment is due and payable); or

         (d)      default in the performance, or breach, of any covenant or
warranty of the Company in respect of the Securities of such series (other
than a covenant or warranty in respect of the Securities of such series a
default in whose performance or whose breach is elsewhere in this Section
specifically dealt with), and continuance of such default or breach for a
period of 60 days after there has been given, by registered or certified
mail, to the Company by the Trustee or to the Company and Trustee by the
Holders of at least 25% in principal amount of the Outstanding Securities
(determined pursuant to Section 2.08) of all series affected thereby, 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)      a court having jurisdiction in the premises entering a
decree or order for relief in respect of the Company in an involuntary case
under the Bankruptcy Law now or hereafter in effect, or appointing a
receiver, liquidator, assignee, custodian, trustee or sequestrator (or
similar official) of the Company or for any substantial part of its property
or ordering the winding up or liquidation of its affairs, and such decree or
order shall remain unstayed and in effect for a period of 60 consecutive
days; or

         (f)      the Company commencing a voluntary case under any
applicable Bankruptcy Law now or hereafter in effect, or consent to the entry
of an order for relief in an involuntary case under any such law, or consent
to the appointment of or taking possession by a receiver,

                                       32

<PAGE>

liquidator, assignee, custodian, trustee or sequestrator (or similar
official) of the Company or for any substantial part of its property, or
making any general assignment for the benefit of creditors; or

         (g)      any other Event of Default provided in the supplemental
indenture or Board Resolutions under which such series of Securities is
issued or in the form of Security for such series.

         If an Event of Default described in clause (a), (b), (c) or (d)
above (if the Event of Default under clause (d) is with respect to less than
all series of Securities then Outstanding) occurs and is continuing, then,
and in each and every such case, unless the principal of all of the
Securities of such series shall have already become due and payable, either
the Trustee or the Holders of not less than 25% in aggregate principal amount
of the Securities of such series then Outstanding hereunder (each such series
voting as a separate class) by notice in writing to the Company (and to the
Trustee if given by Securityholders), may declare the entire principal (or,
if the Securities of such series are Discount Securities, such portion of the
principal amount as may be specified in the terms of such series) of all
Securities of such series and the interest accrued thereon and Additional
Amounts payable in respect thereof, if any, to be due and payable
immediately, and upon any such declaration the same shall become immediately
due and payable. If an Event of Default described in Clause (d) (if the Event
of Default under clause (d) is with respect to all series of Securities then
Outstanding), (e) or (f) occurs and is continuing, then and in each and every
such case, unless the principal of all the Securities shall have already
become due and payable, either the Trustee or the Holders of not less than
25% in aggregate principal amount of all the Securities then Outstanding
hereunder (treated as one class), by notice in writing to the Company (and to
the Trustee if given by Securityholders), may declare the entire principal
(or, if any Securities are Discount Securities, such portion of the principal
as may be specified in the terms thereof) of all the Securities then
Outstanding and interest accrued thereon and Additional Amounts payable in
respect thereof, if any, to be due and payable immediately, and upon any such
declaration the same shall become immediately due and payable.

         The foregoing provisions, however are subject to the condition that
if, at any time after the principal (or, if the Securities are Discount
Securities, such portion of the principal as may be specified in the terms
thereof) of the Securities of any series (or of all the Securities, as the
case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the moneys due shall have been obtained
or entered as hereinafter provided, the Company shall pay or shall deposit
with the Trustee a sum sufficient to pay all matured installments of interest
upon and any Additional Amounts payable in respect of all the Securities of
such series (or of all the Securities, as the case may be) and the principal
of any and all Securities of such series (or of all the Securities, as the
case may be) which shall have become due otherwise than by acceleration (with
interest upon such principal and, to the extent that payment of such interest
is enforceable under applicable law, on overdue installments of interest or
any Additional Amounts, at the same rate as the rate of interest or Yield to
Maturity (in the case of Discount Securities) specified in the Securities of
such series (or at the respective rates of

                                       33

<PAGE>

interest or Yields to Maturity of all the securities, as the case may be, to
the date of such payment or deposit) and such amount as shall be sufficient
to cover reasonable compensation to the Trustee, its agents, attorneys and
counsel, and all other expenses and liabilities incurred, and all advances
made, by the Trustee except as a result of negligence or bad faith, and if
any and all Events of Default under the Indenture, other than the non-payment
of the principal of Securities which shall have become due by acceleration,
shall have been cured, waived or otherwise remedied as provided herein --
then the Holders of a majority in aggregate principal amount of all the
Securities of such series, each series voting as a separate class (or of all
the Securities, as the case may be, voting as a single class) then
Outstanding, by written notice to the Company and to the Trustee, may waive
all defaults with respect to such series (or with respect to all the
Securities, as the case may be) and rescind and annul such declaration and
its consequences, but no such waiver or rescission and annulment shall extend
to or shall affect any subsequent default or shall impair any right
consequent thereon.

         For all purposes under this Indenture, if a portion of the principal
of any Discount Securities shall have been accelerated and declared due and
payable pursuant to the provisions hereof, then, from and after such
declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Discount Securities shall be deemed, for all
purposes hereunder, to be such portion of the principal thereof as shall be
due and payable as a result of such acceleration, and payment of such portion
of the principal thereof as shall be due and payable as a result of such
acceleration, together with interest, if any, thereon and all other amounts
owing thereunder, shall constitute payment in full of such Discount
Securities.

         Section 6.02.  COLLECTION OF INDEBTEDNESS BY TRUSTEE; TRUSTEE MAY
PROVE DEBT.

         The Company covenants that (a) in the case default shall be made in
the payment of any installment of interest on or any Additional Amounts
payable in respect of any of the Securities of any series when such interest
or Additional Amounts shall have continued for a period of 30 days or (b) in
case principal shall have become due and payable, and such default shall be
made in the payment of all or any part of the principal of any of the
Securities of any series when the same shall have become due and payable,
whether upon maturity of the Securities of such series, or upon any
redemption or by declaration or otherwise -- then, upon demand of the
Trustee, the Company will pay to the Trustee for the benefit of the Holders
of the Securities of such series the whole amount that then shall have become
due and payable on all Securities of such series, and such coupons, for
principal, interest or Additional Amounts, if any, as the case may be (with
interest to the date of such payment upon the overdue installments of
interest or any Additional Amounts at the same rate as the rate of interest
or Yield to Maturity (in the case of Discount Securities) specified in the
Securities of such series); and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection including
reasonable compensation to the Trustee and each predecessor Trustee, their
respective agents, attorneys and counsel, and any expenses and liabilities
incurred, and all advances made, by the Trustee and predecessor Trustee
except as a result of its negligence or bad faith.

                                       34

<PAGE>

         In case the Company shall fail forthwith to pay such amounts upon
such demand, the Trustee, in its own name and as trustee of an express trust,
shall be entitled and empowered to institute any action or proceeding at law
or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceedings to judgment or final decree, and may
enforce any such judgment or final decree against the Company or other
obligor upon such Securities and collect in the manner provided by law out of
the property of the Company or other obligor upon such Securities, wherever
situated, the moneys adjudged or decreed to be payable.

         In case there shall be pending proceedings relative to the Company
or any other obligor upon the Securities under Bankruptcy Law, or in case a
receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken
possession of the Company or its property or such other obligor, or in case
of any other comparable judicial proceedings relative to the Company or other
obligor upon the Securities or any series, or to the creditors or property of
the Company or such other obligor, the Trustee, irrespective of whether the
principal of any 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 pursuant to the provisions of this
Section, shall be entitled and empowered, by intervention in such proceedings
or otherwise:

          (a)      to file and prove a claim or claims for the whole amount
of principal, interest (or, if the Securities of any series are Discount
Securities, such portion of the principal amount as may be specified in the
terms of such series) and any Additional Amounts owing and unpaid in respect
of the Securities of any series, 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 reasonable compensation to the Trustee and each
predecessor Trustee, and their respective agents, attorneys and counsel, and
for reimbursement of all expenses and liabilities incurred, and all advances
made, by the Trustee and each predecessor Trustee, except as a result of
negligence or bad faith) and of the Securityholders allowed in any judicial
proceedings relative to the Company or other obligor upon the Securities of
any series, or to the creditors or property of the Company or such other
obligor,

         (b)      unless prohibited by applicable law and regulations, to
vote on behalf of the Holders of the Securities of any series in any election
of a trustee or a standby trustee in arrangement, reorganization, liquidation
or other bankruptcy or insolvency proceedings or person performing similar
functions in comparable proceedings, and

         (c)      to collect and receive any moneys or other property payable
or deliverable on any such claims, and to distribute all amounts received
with respect to the claims of the Securityholders and of the Trustee on their
behalf; and any trustee, receiver, or liquidator, custodian or other similar
official is hereby authorized by each of the Securityholders to make payments
to the Trustee, and in the event that the Trustee shall consent to the making
of payments directly to the Securityholders, to pay to the Trustee such
amounts as shall be sufficient to cover reasonable compensation to the
Trustee, each predecessor trustee and their

                                       35

<PAGE>

respective agents, attorneys and counsel, and all other expenses and
liabilities incurred, and all advances made, by the trustee and each
predecessor Trustee except as a result of negligence or bad faith and all
other amounts due to the Trustee or any predecessor Trustee under this
Indenture.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities of any series or the rights of any
Holder thereof, or to authorize the Trustee to vote in respect of the claim
of any Securityholder in any such proceeding except, as aforesaid, to vote
for the election of a trustee in bankruptcy or similar person.

         All rights of action and of asserting claims under this Indenture,
or under any of the Securities of any series or coupons appertaining to such
Securities, may be enforced by the Trustee without the possession of any of
the Securities of such series or coupons appertaining to such Securities or
the production thereof at any trial or other proceedings relative thereto,
and any such action or proceedings instituted by the Trustee shall be brought
in its own name as trustee of an express trust, and any recovery or judgment,
subject to the payment of the expenses, disbursements and compensation of the
Trustee, each predecessor Trustee and their respective agents and attorneys,
shall be for the ratable benefit of the Holders of the Securities or of
coupons appertaining to such Securities in respect of which action was taken.

         In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the
Holders of the Securities or coupons appertaining to such Securities in
respect to which such action was taken, and it shall not be necessary to make
any Holders of such Securities or coupons appertaining to such Securities
parties to any such proceedings.

         Section 6.03.  APPLICATION OF PROCEEDS.

         Any moneys collected by the Trustee pursuant to this Article with
respect to the Securities of any series shall be applied in the following
order at the date or dates fixed by the Trustee and, in case of the
distribution of such moneys on account of principal, interest or any
Additional Amounts, upon presentation of the several Securities and coupons
appertaining to such Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereof the payment, or issuing
Securities of such series in reduced principal amounts in exchange for the
presented Securities of like series if only partially paid, or upon surrender
thereof if fully paid.

         FIRST:  to the Trustee and any predecessor Trustee for amounts due
under Section 7.07.

                                       36

<PAGE>

         SECOND:  to the Holders of Securities of such series or coupons
appertaining thereto for amounts due and unpaid on the Securities and coupons
for principal, interest and Additional Amounts, ratably, without preference
or priority of any kind, according to the amounts due and payable on the
Securities and coupons for principal, interest and Additional Amounts,
respectively; and

         THIRD:  to the Person or Persons lawfully entitled thereto.

         Section 6.04.  SUITS FOR ENFORCEMENT.

         In case an Event of Default has occurred, has not been waived and is
continuing, the Trustee may in its discretion proceed to protect and enforce
the rights vested in it by this Indenture by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce
any of such rights, either at law or in equity or in bankruptcy or otherwise,
whether for the specific enforcement of any covenant or agreement contained
in this Indenture or in aid of the exercise of any power granted in this
Indenture or to enforce any other legal or equitable right vested in the
Trustee by this Indenture or by law.

         Section 6.05.  RESTORATION OF RIGHTS ON ABANDONMENTS OF PROCEEDINGS.

         In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discounted or abandoned
for any reason, or shall have been determined adversely to the Trustee, then
and in every such case the Company and the Trustee shall be restored
respectively to their former positions and rights hereunder, and all rights,
remedies and powers of the Company, the Trustee and the Securityholders shall
continue as though no such proceedings had been taken.

         Section 6.06.  LIMITATIONS ON SUITS BY SECURITYHOLDERS.

         No Holder of any Security of any series or of any coupon
appertaining thereto shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or
in equity or in bankruptcy or otherwise upon or under or with respect to this
Indenture, or for the appointment of a trustee, receiver, liquidator,
custodian or other similar official or for any other remedy hereunder, unless
such Holder previously shall have given to the Trustee written notice of a
Continuing Event of Default, as hereinbefore provided, and unless also the
Holders of not less than 25% in aggregate principal amount of the Securities
of such series then Outstanding shall have made written request upon the
Trustee to institute such action or proceedings in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as
it may require against the costs, expenses and liabilities to be incurred
therein or thereby and the Trustee for 60 days after its receipt of such
notice, request and offer of indemnity shall have failed to institute any
such action or proceeding and the Holders of a majority in principal amount
of the outstanding Securities [of such series] shall have not given the
Trustee a direction inconsistent with such request, it being understood and
intended, and

                                       37

<PAGE>

being expressly covenanted by the taker and Holder of every Security or
coupon with every other taker and Holder and the Trustee, that no one or more
Holders of Securities of any series or coupons appertaining to such
Securities shall have any right in any manner whatever by virtue or by
availing of any provision of this Indenture to affect, disturb or prejudice
the rights of any other such Holder of Securities or coupons appertaining to
such Securities, or to obtain or seek to obtain priority over or preference
to any other such Holder or to enforce any right under this Indenture, except
in the manner herein provided and for the equal, ratable and common benefit
of all Holders of Securities of the applicable series and coupons
appertaining to such Securities. For the protection and enforcement of the
provisions of this Section, each and every Securityholder and the Trustee
shall be entitled to such relief as can be given either at law or in equity.

         Section 6.07.  UNCONDITIONAL RIGHT OF SECURITYHOLDER TO INSTITUTE
CERTAIN SUITS.

         Notwithstanding any other provision in this Indenture and any
provision of any Security, the right of any Holder of any Security or coupon
to receive payment of the principal of, interest on and any Additional
Amounts in respect of such Security or coupon on or after the respective due
dates expressed in such Security or coupon, or to institute suit for the
enforcement of any such payment on or after such respective dates, shall not
be impaired or affected without the consent of such Holder.

         Section 6.08.  POWERS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT
WAIVER OF DEFAULT.

         Except as provided in Section 6.06, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders of Securities or
coupons 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.

         No delay or omission of the Trustee or of any Holder of Securities
or coupons to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power or
shall be construed to be a waiver of any such Event of Default or an
acquiescence therein; and, subject to Section 6.06, every power and remedy
given by this Indenture or by law to the Trustee or to the Holders of
Securities or coupons may be exercised from time to time, and as often as
shall be deemed expedient, by the Trustee or by the Holders of Securities or
coupons.

         Section 6.09.  CONTROL BY HOLDERS OF SECURITIES.

         The Holders of a majority in aggregate principal amount of the
Securities of each series affected (with each series voting as a separate
class) at the time Outstanding shall have the right

                                       38

<PAGE>

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 by this
Indenture; provided that such direction shall not be otherwise than in
accordance with law and the provisions of this Indenture and provided further
that (subject to the provisions of Section 6.01) the Trustee shall have the
right to decline to follow any such direction if the Trustee, being advised
by counsel, shall determine that the action or proceeding so directed may not
lawfully be taken or if the Trustee in good faith by its board of directors,
the executive committee, or a trust committee of two or more directors or
responsible officers of the Trustee, which may include Trust Officers, shall
determine that the action or proceedings so directed would involve the
Trustee in personal liability or if the Trustee in good faith shall so
determine that the actions or forbearances specified in or pursuant to such
direction would be unduly prejudicial to the interests of Holders of the
Securities of all series so affected not joining in the giving of said
direction, it being understood that the Trustee shall have no duty to
ascertain whether or not such actions or forbearances are unduly prejudicial
to such Holders.

         Nothing in this Indenture shall impair the right of the Trustee in
its discretion to take any action deemed proper by the Trustee and which is
not inconsistent with such direction or directions by Securityholders.

         Section 6.10.  WAIVER OF PAST DEFAULTS.

         Prior to the declaration of the acceleration of the maturity of the
Securities of any series as provided in Section 6.01, the Holders of a
majority in aggregate principal amount of the Securities of such series at
the time Outstanding may on behalf of the Holders of all the securities of
such series waive any past default or Event of Default described in clause
(c) of Section 6.01 (or, in the case of an event specified in clause (d) of
Section 6.01 which relates to less than all series of Securities then
Outstanding, the Holders of a majority in aggregate principal amount of the
Securities then Outstanding affected thereby (each series voting as a
separate class) may waive any such default or Event of Default, or, in the
case of an event specified in clause (d) (if the Event of Default under
clause (d) relates to all series of Securities then Outstanding), (e) or (f)
of Section 6.01 the Holders of Securities of a majority in principal amount
of all the Securities then Outstanding (voting as one class) may waive any
such default or Event of Default), and its consequences except a default in
respect of a covenant or provision hereof which cannot be modified or amended
without the consent of the Holder of each Security affected. In the case of
any such waiver, the Company, the Trustee and the Holders of the Securities
of such series shall be restored to their former positions and rights
hereunder, respectively; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

         Upon any such waiver, such default shall cease to exist and be
deemed to have been cured and not to have occurred, and any Event of Default
arising therefrom shall be deemed to have been cured, and not to have
occurred for every purpose of this Indenture; but no such waiver shall extend
to any subsequent or other default or Event of Default or impair any right
consequent thereon.

<PAGE>

         Section 6.11.  TRUSTEE TO GIVE NOTICE OF DEFAULT, BUT MAY WITHHOLD
IN CERTAIN CIRCUMSTANCES.

         The Trustee shall, within ninety days after the occurrence of a
default with respect to the Securities of any series, give notice of all
defaults with respect to that series known to the Trustee (i) if any Bearer
Securities of that series are then Outstanding, to the Holders thereof, by
publication at least once in an Authorized Newspaper in the Place of Payment,
(ii) if any Bearer Securities of that series are then Outstanding, to all
Holders thereof who have filed their names and addresses with the Trustee, by
mailing such notice to such Holders at such addresses and (iii) to all
Holders of then Outstanding Registered Securities of that series, by mailing
such notice to such Holders at their addresses as they shall appear in the
registry books, unless in each case such defaults shall have been cured
before the mailing or publication of such notice (the term "defaults") for
the purpose of this Section being hereby defined to mean any event or
condition which is, or with notice or lapse of time or both would become, an
Event of Default); provided that, except in the case of default in the
payment of the principal of or interest or Additional Amounts, if any, on any
of the Securities of such series or in the payment of any sinking or purchase
fund installment, the Trustee shall be protected in withholding such notice
if and so long as the board of directors, the executive committee, or a trust
committee comprised of two or more directors or trustees and/or responsible
officers of the Trustee, which may include Trust Officers, in good faith
determines that the withholding of such notice is in the interests of the
Securityholders of such series.

         Section 6.12.  RIGHT OF COURT TO REQUIRE FILING OF UNDERTAKING TO
PAY COSTS.

         All parties to this Indenture agree, and each Holder of any Security
or coupon 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 (other than the Trustee) 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 Trustee, to any suit
instituted by any Securityholder or group of Securityholders of any series
holding in the aggregate more than 10% in aggregate principal amount of the
Outstanding Securities of such series, or, in the case of any suit relating
to or arising under clause (d) of Section 6.01 (if the suit relates to
Securities of more than one but less than all series), 10% in aggregate
principal amount of Securities Outstanding affected thereby, or in the case
of any suit relating to or arising under clause (d) (if the suit under clause
(d) relates to all the Securities then Outstanding), (e) or (f) of Section
6.01, 10% in aggregate principal amount of all Securities Outstanding, or to
any suit instituted by any Securityholder for the enforcement of the payment
of the principal of or interest on any Security on or after the due date
expressed in such Security or any date fixed for redemption.

                                      40

<PAGE>

         The Holders of a majority in principal amount of the Outstanding
Securities of such series by notice to the Company and the Trustee may
rescind an acceleration and its consequences if (i) all existing Events of
Default with respect to the Securities of such series, other than the
non-payment of the principal of the Securities which have become due solely
by such declaration of acceleration, have been cured or waived, (ii) the
Company has paid or deposited with the Trustee a sum sufficient to pay the
whole amount then due and payable on such Securities and any coupons
appertaining thereto for principal and interest and Additional Amounts, if
any, with interest upon the overdue principal and, to the extent that payment
of such interest shall be legally enforceable, upon overdue installments of
interest or any Additional Amounts, at the rate or rates borne by or provided
for 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, and (iii) the rescission would not conflict
with any judgment or decree. No such rescission shall have any effect on any
subsequent default or impair any right consequent thereon.

         Section 6.13      WAIVER OF STAY OR EXTENSION LAWS.

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

                                  ARTICLE SEVEN
                                     TRUSTEE

         Section 7.01.  DUTIES OF TRUSTEE.

         (a)      If an Event of Default has occurred and is continuing, the
Trustee shall exercise its rights and powers hereunder and use the same
degree of care and skill in its 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:

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

                                       41

<PAGE>

                  (2)      In the absence of bad faith on its part, the
Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions
furnished to the Trustee and conforming to the requirements of this
Indenture. The Trustee, however, shall examine the certificates and opinions
to determine whether or not they conform to the requirements of this
Indenture (but need not confirm or investigate the accuracy of mathematical
calculations or other facts stated therein).

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

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

                  (2)      The Trustee shall not be liable for any error of
judgment made in good faith by a responsible officer or officers of the
Trustee, which may include Trust Officers, unless it is proved that the
Trustee was negligent in ascertaining the pertinent facts.

                  (3)      The Trustee shall not be liable with respect to
any action it takes or omits to take in good faith in accordance with a
direction received by it pursuant to Section 6.09.

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

         (d)      Every provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (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)      Money held by the Trustee in trust hereunder need not be
segregated except to the extent required by law. The Trustee shall not be
liable for interest on any money received by it except as the Trustee may
agree with the Company.

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

         Every provision in this Indenture relating to the conduct of or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the Trust
Indenture Act.

         Except as provided in Section 7.01:

         (a)      The Trustee may conclusively rely on any document believed
by it to be genuine and to have been signed or presented by the proper Person
or Persons. 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 of the Company or an Opinion of Counsel. The
Trustee shall not be liable for any action it takes or omits to take in good
faith and in reliance on such Officers' Certificate or Certificates 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.

omits to take in good faith which it believes to be authorized or within its
rights or powers.

         (e)      Any demand, request, direction or notice from the Company
mentioned herein shall, unless otherwise specifically provided, be
sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution.

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

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

         (h)      the Trustee shall not be deemed to have notice of any
Default or Event of Default unless a Trust Officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such
a default is received by the Trustee at the Corporate Trust Office of the
Trustee, and such notice references the Securities and this Indenture;

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

         (j)      the Trustee may request that the Company deliver an
Officers' Certificate setting forth the names of individuals and/or titles or
officers authorized at such time to take specified actions pursuant to this
Indenture, which Officers' Certificate may be signed by any person authorized
to sign an Officers' Certificate, including any person specified as so
authorized in any such certificate previously delivered and not superseded.

         Section 7.03.  INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities or coupons and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not
Trustee. Any Agent may do the same with like rights. The Trustee, however,
must comply with Sections 7.10 and 7.11.

         Section 7.04.  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 Securities or the proceeds from the Securities; and it
shall not be responsible for any statement in the Securities other than its
certificate of authentication.

         Section 7.05.  NOTICE OF DEFAULTS.

         If a Default occurs and is continuing with respect to Securities and
if it is actually known to the Trustee, the Trustee shall give to each Holder
of Securities of any series to which such Default relates, in the manner and
to the extent provided in TIA Section 313(c), and otherwise as provided in
Section 13.02 of this Indenture, notice of the Default within 90 days after
it occurs. Except in the case of a Default in payment of principal of or
interest or Additional Amounts, if any, on a Security of any series, or in
the payment of any sinking or purchase fund installment, the Trustee may
withhold the notice if and so long as the board of directors of the Trustee,
the executive committee or a trust committee of directors and/or of
responsible officers, which may include Trust Officers, of the Trustee in
good faith determines that withholding the notice is in the interests of
Holders of Securities of such series or the coupon appertaining thereto.

         Section 7.06.  REPORTS BY TRUSTEE TO HOLDERS.

         Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, the Trustee shall mail to each Securityholder a
brief report dated as of such May 15 that complies with TIA Section 313(a).
The Trustee also shall comply with TIA Section 313(b)(2). Reports to Holders
pursuant to this Section 7.06 shall be transmitted in the manner and to the
extent provided in TIA Section 313(c).

         A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and each stock exchange on which any Securities
are listed.

         The Company agrees to notify the Trustee whenever the Securities of
any series become listed on any stock exchange or any delisting thereof.

         Section 7.07.  COMPENSATION AND INDEMNITY.

         The Company shall pay to the Trustee from time to time such
compensation as the Company and the Trustee shall from time to time agree in
writing for all services rendered by it hereunder (which compensation shall
not be limited by any provision of law in regard to the compensation of a
Trustee of an express trust). The Company shall reimburse the Trustee and any
predecessor Trustee upon request for all reasonable out-of-pocket expenses
and advances incurred or made by it. Such expenses shall include the
reasonable compensation and expenses of the Trustee's agents and counsel. The
Company shall indemnify each of the Trustee and any predecessor Trustee and
their agents against any loss damage claim, expense or liability (including
legal fees and expenses) incurred by it in connection with the acceptance and
administration of the trust and the performance of its duties hereunder,
including the costs and expenses and disbursements of defending itself
against any claim or liability in connection with the exercise or performance
of any of its powers or duties hereunder. The Trustee shall notify the
Company promptly of any claim asserted against it for which it may seek
indemnity; provided, however, that the failure to give the Company any notice
of any claim shall not in any way affect the rights of the Trustee hereunder
to indemnification for such claim. The Company need not reimburse any expense
or indemnify against any loss or liability incurred by the Trustee or any
predecessor Trustee to the extent due to its own negligence, willful
misconduct or bad faith.

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

         When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01 (e) and (f) occurs, the expenses and the
compensation for services are intended to constitute expenses of
administration under any Bankruptcy Law. The term "Bankruptcy Law" means
Title 11, U.S. Code.

         The provisions of this Section 7.07 shall survive termination of
this Indenture or the resignation and removal of the Trustee.

         For purposes of this Section, the term "Trustee" shall include any
predecessor Trustee, provided that any Trustee hereunder shall not be liable
for the willful misconduct, negligence or bad faith of any other Trustee
hereunder.

         Section 7.08.  REPLACEMENT OF TRUSTEE.

         The Trustee may resign by so notifying the Company. The Holders of a
majority in principal amount of the Outstanding Securities may remove the
Trustee by so notifying the Trustee and may appoint a successor Trustee with
respect to the Securities. The Company may by or pursuant to a Board
Resolution remove the Trustee with respect to all Securities if:

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

                  (2)      the Trustee is adjudged bankrupt or insolvent;

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

                  (4)      the Trustee becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. As soon as possible
after that, the retiring Trustee shall, upon payment of its charges, transfer
all property held by it as Trustee to the successor Trustee, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under
this Indenture. A successor Trustee shall give notice of its succession to
each Holder of Securities.

         If a successor Trustee does not take office within 45 days after the
retiring Trustee resigns or is removed, the retiring Trustee, at the
Company's expense, the Company or the Holders of a majority in principal
amount of the Outstanding Securities may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

         If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

         Section 7.09.  SUCCESSOR TRUSTEE BY MERGER, ETC.

                                       46

<PAGE>

         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, provided such corporation shall be otherwise
qualified and eligible under this article.

         Section 7.10.  ELIGIBILITY; DISQUALIFICATION.

         The Trustee shall at all times satisfy the requirements of TIA
Section 310(a)(1). The Trustee shall have a combined capital and surplus of
at least $50,000,000 as set forth in its most recent published annual report
of condition. If any series of Securities is admitted to trading on the New
York Stock Exchange, Inc., or any successor thereto, the Trustee shall
maintain an office or agency in The Borough of Manhattan, The City of New
York, New York as long as such series of Securities shall be so admitted. The
Trustee shall comply with TIA Section 310(b).

         Section 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         The Trustee shall comply with 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.  For the purposes of Section 311(b) of the Trust Indenture Act:
(a) the term "cash transaction" shall have the meaning provided in Rule
11(b)-4 under the Trust Indenture Act, and (b) the term"self-liquidating
paper" shall have the meaning provided in Rule 11(b)-6 under the Trust
Indenture Act.

                             DISCHARGE OF INDENTURE

         Section 8.01.  TERMINATION OF THE COMPANY'S OBLIGATIONS.

         The Company may terminate all of its obligations under the
Securities of any series and this Indenture with respect to such series if
all Securities of such series previously authenticated and delivered (other
than destroyed, lost or stolen Securities of such series which have been
replaced or paid) and all coupons appertaining thereto (other than (i)
coupons appertaining to Bearer Securities surrendered for exchange for
Registered Securities and maturing after such exchange, whose surrender is
not required or has been waived as provided in Section 2.06, (ii) Securities
and coupons which have been destroyed, lost or stolen and which have been
replaced or paid as provided in Section 2.07, and (iii) Securities and
coupons for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust, as provided in Section 4.03 or 8.04)
have been delivered to the Trustee for cancellation or if:

                  (1)      the Securities of such series mature within one
year or all of them are to be called for redemption within one year under
arrangements satisfactory to the Trustee for giving the notice of redemption;

                                       47

<PAGE>

                  (2)      the Company irrevocably deposits in trust with the
Trustee money or Government Obligations sufficient to pay principal of and
any interest and Additional Amounts on the Securities of such series to
maturity or redemption, as the case may be (other than moneys paid to the
Company or discharged from trust in accordance with Section 4.03 or 8.04); and

                  (3)      the Company shall have 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.

         The Company's obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07,
7.07, 7.08, and 8.03 with respect to the Securities of such series, however,
shall survive so long as any principal of, interest, if any, or any
Additional Amounts on the Securities of such series, and coupons appertaining
thereto, remains unpaid. Thereafter the Company's obligations in Section 7.07
shall survive.

         After a deposit of such moneys, and delivery of the Officers'
Certificate and Opinion of Counsel required by clause (3) above, the Trustee
upon request shall acknowledge in writing the discharge of the Company's
obligations under the Securities of such series and this Indenture with
respect to the Securities of such series except for those surviving
obligations specified above.

         Section 8.02.  TERMINATION OF THE COMPANY'S OBLIGATIONS UNDER
CERTAIN CIRCUMSTANCES.

         Unless otherwise provided in a Board Resolution of the Company
delivered to the Trustee pursuant to Section 2.01 or an indenture
supplemental hereto with respect to the Securities of any series, the
Company, at its option, either (a) shall be deemed to have been Discharged
(as defined below) from its obligations with respect to the Securities of any
series, and coupons appertaining thereto, on the ninety-first day after the
applicable conditions set forth below have been satisfied or (b) shall cease
to be under any obligation to comply with any term, provision or condition
set forth in Sections 4.04, 4.05, 4.06 and 4.07 and Sections 6.01 and 6.02 as
they relate to Section 6.01(d), with respect to the Securities of any series
and any coupons appertaining thereto and any other covenants provided in the
Board Resolution of the Company (except Section 7.07) delivered to the
Trustee pursuant to Section 2.01 or an indenture supplemental hereto with
respect to the Securities of such series and any coupons appertaining thereto
at any time after the applicable conditions set forth below have been
satisfied:

                  (1)      the Company shall have deposited or caused to be
deposited irrevocably with the Trustee as trust funds in trust, specifically
pledged as security for, and dedicated solely to, the benefit of the Holders
of the Securities of such series and any coupons appertaining thereto (A)
money in an amount, or (B) Government Obligations which through the payment
of interest and principal in respect thereof in accordance with their terms
will provide, not later than one day (or, if such day is a Legal Holiday, the
first day preceding such day which is not a Legal

                                       48

<PAGE>

Holiday) before the due date of any payment, money in an amount, or (C) a
combination of (A) and (B), sufficient, in the opinion of a recognized firm
of Independent Public Accountants selected by the Company expressed in a
written certification thereof delivered to the Trustee, to pay and discharge
each installment of principal (including mandatory sinking fund payments) of,
and interest, if any, and Additional Amounts, if any, on the Outstanding
Securities of such series on the dates such installments of principal,
interest, if any, and Additional Amounts, if any, are due (taking into
account any redemption pursuant to optional sinking fund payments notice of
which redemption is provided to the Trustee at the time of the deposit
referred to in this paragraph (1));

                  (2)      if the Securities of such series are then listed
on the New York Stock Exchange, the Company shall have delivered to the
Trustee an Opinion of Counsel to the effect that the Company's exercise of
its option under this paragraph would not cause such Securities to be
delisted;

                  (3)      no Event of Default, or event which with the
giving of notice or lapse of time, or both, would become an Event of Default,
with respect to the Securities of such series shall have occurred and be
continuing on the date of such deposit and the Company shall have furnished
to the Trustee an Officers' Certificate to such effect; and

                  (4)      the Company shall have delivered to the Trustee an
Opinion of Counsel to the effect that Holders of the Securities of such
series will not recognize income, gain or loss for United States Federal
income tax purposes as a result of the exercise of the option under this
Section 8.02 and will be subject to United States Federal income tax on the
same amount and in the same manner and at the same times as would have been
the case if such option had not been exercised, and, in the case of
Securities being Discharged, such opinion shall be accompanied by a private
letter ruling to that effect received from the United States Internal Revenue
Service or a revenue ruling pertaining to a comparable form of transaction to
that effect published by the United States Internal Revenue Service.

         "Discharged" means, for purposes of this Section 8.02, that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by, and obligations under, the Securities of any series and to
have satisfied all the obligations under this Indenture relating to the
Securities of such series (and the Trustee, at the expense of the Company,
shall execute such instruments as may be requested by the Company
acknowledging the same), except (A) the rights of Holders of Securities of
such series or the coupons, if any, appertaining thereto, as the case may be,
to receive, solely from the trust fund described above, payment of the
principal of and interest, if any, and Additional Amounts, if any, on such
Securities when such payments are due; (B) the Company's obligations with
respect to such Securities under Sections 2.03, 2.04, 2.05, 2.06, 2.07, 7.07,
7.08 and 8.03; and (C) the rights, powers, duties and immunities of the
Trustee hereunder. Notwithstanding the satisfaction and discharge of this
Indenture with respect to any series of Securities, the obligations of the
Company to the Trustee and any predecessor Trustee under Section 7.07 shall
survive.

Obligations, the principal and interest in respect thereof, with respect to
Securities of any series shall be held irrevocably in trust and applied by it
to the payment in accordance with the provisions of the Securities of such
series and this Indenture, either directly or through any Paying Agent for
the Securities of that series (including the Company if acting as its own
Paying Agent), to the Holders of the Securities of such series or the
coupons, if any, appertaining thereto, as the case may be, for the payment or
redemption of which such money has been deposited with the Trustee, of all
sums due and to become due thereon for principal, interest, if any, and

         The Trustee and the Paying Agent shall promptly pay to the Company

any Paying Agent, or then held by the Company, under this Article Eight in
trust for the payment of the principal of, interest or Additional Amounts, if
any, on any Security and remaining unclaimed for two years after such
principal, interest or Additional Amounts have become due and payable shall
be paid to the Company on request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent with respect
to such trust money, and all liability of the Company as trustee thereof,
shall thereupon cease.

         Section 8.05.  INDEMNITY FOR GOVERNMENT OBLIGATIONS.

         The Company shall pay and shall indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against deposited Government

additional covenant, restriction, condition or provision such supplemental
indenture may provide for a particular period of grace after default (which
period may be shorter or longer than that allowed in the case of other
defaults) or may provide for immediate enforcement upon such an Event of
Default or may limit the remedies available to the Trustee upon such an Event
of Default or may limit the right of the Holders of a majority in aggregate

prior to the execution of such supplemental indenture and entitled to the
benefit of such provision nor (B) modify the rights of the Holder of any such
Security with respect to such provision.

         The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, to make any further appropriate
agreements and stipulations which may be therein contained and to accept the
conveyance, transfer, assignment, mortgage or pledge of any property
thereunder, but the Trustee shall not be obligated to enter into any such
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

         Any supplemental indenture authorized by the provisions of this
Section may be executed without the consent of the Holders of any of the
Securities at the time Outstanding, notwithstanding any of the provisions of
Section 9.02.

         Section 9.02.  WITH CONSENT OF HOLDERS.

         With the consent of the Holders of not less than a majority of the
principal amount of the Securities at the time Outstanding in each series
affected by such supplemental indenture (voting as one class), the Company,
when authorized by a resolution of its Board of Directors, and the Trustee
may, from time to time and at any time, enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of this Indenture or any
supplemental indenture or of modifying in any manner the rights of the
Holders of the Securities of each such series or of the coupons appertaining
to such Securities; provided, that no such supplemental indenture shall,
without the consent of each Securityholder affected:

                  (1)      reduce the amount of Securities whose Holders must

<PAGE>

                  (7)      change a Place of Payment; or

                  (8)      make any Security payable in currency other than
that stated in the Security.

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

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

         Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the
Trustee shall give a notice thereof (i) to the Holders of then Outstanding
Registered Securities of each series affected thereby, by mailing a notice
thereof by first-class mail to such Holders at their addresses as they shall
appear on the Security Register, (ii) if any Bearer Securities of a series
affected thereby are then Outstanding, to the Holders thereof who have filed
their names and addresses with the Trustee, by mailing a notice thereof by
first-class mail to such Holders at such addresses as were so furnished to
the Trustee and (iii) if any Bearer Securities of a series affected thereby
are then Outstanding, to all Holders thereof, by publication of a notice
thereof at least once in an Authorized Newspaper in the Place of Payment, and
in each case such notice shall set forth in general terms the substance of
such supplemental indenture. Any failure the Trustee to give such notice, or
any defect therein, shall not, however, in any way impair or affect the
validity of any such supplemental indenture.

         Section 9.03.  COMPLIANCE WITH TRUST INDENTURE ACT.

         Every amendment to or supplement of this Indenture or the Securities
shall comply with the TIA as then in effect.

         Section 9.04.  REVOCATION AND EFFECT OF CONSENTS.

         A consent to an amendment, supplement or waiver to any other action
hereunder by a Holder of a Security of any series shall bind the Holder and
every subsequent Holder of a Security or portion of a Security of that series
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent is not made on any Security. Any such Holder or
subsequent Holder, however, may revoke the consent as to his Security or
portion of a

                                       53

<PAGE>

Security. Such revocation shall be effective only if the Trustee receives the
notice of revocation before the date the amendment, supplement or waiver or
other action becomes effective.

         After an amendment, supplement or waiver with respect to a series of
Securities becomes effective, it shall bind every Holder of Securities of
that series.

          The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Securityholders entitled to take any
action under this Indenture by vote or consent.  If such record date is
fixed, the Company shall notify the Trustee of such date.  Such record date
shall be the later of 30 days prior to the first solicitation of such consent
or vote or the date of the most recent list of Holders of the affected
Securities furnished to the Trustee pursuant to Section 2.05 prior to such
solicitation.  If a record date is fixed, those persons who were
Securityholders at such record date (or their duly designated proxies), and
only those persons, shall be entitled to take such action by vote or consent
or to revoke any vote or consent previously given, whether or not such
persons continue to be Securityholders after such record date.

         Section 9.05.  NOTATION ON OR EXCHANGE OF SECURITIES.

         If an amendment, supplement or waiver changes the terms of a
Security, the Trustee may request the Holder of the Security to deliver it to
the Trustee. The Trustee may then place an appropriate notation on the
Security about the changed terms and return it to the Holder. Alternatively,
if the Company so determines, the Company in exchange for the Security shall
issue and the Trustee shall authenticate a new Security that reflects the
changed terms.  Failure to make the appropriate notation or to issue a new
Security shall not affect the validity of such amendment.

         Section 9.06.  TRUSTEE TO SIGN AMENDMENTS, ETC.

         The Trustee shall sign any amendment or supplement authorized
pursuant to this Article if the amendment or supplement does not adversely
affect the rights, duties, liabilities (present or potential), or immunities
of the Trustee. If it does, the Trustee may but need not sign it. In signing
such amendment or supplement, the Trustee shall be entitled to receive and
(subject to Sections 7.01 and 7.02) shall be fully protected in relying upon
an Opinion of Counsel stating that such amendment or supplement is authorized
or permitted by this Indenture.

                      REPAYMENT AT THE OPTION OF HOLDERS

         Section 10.01.  APPLICABILITY OF ARTICLE.

         Securities of any series which are repayable at the option of the
Holders thereof before their maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount
of Securities pursuant to such option of the Holder to require repayment of
Securities before their maturity shall not operate as a payment, redemption
or satisfaction of the indebtedness represented by such Securities unless and
until the Company, at its option, shall deliver or surrender the same to the
Trustee with a directive that such Securities be canceled. Notwithstanding
anything to the contrary contained in this Article Ten, in connection with
any repayment of Securities, the Company may arrange for the purchase of any
Securities by an agreement with one or more investment bankers or other
purchasers to purchase such Securities by paying to the Holders of such
Securities on or before the close of business on the repayment date an amount
not less than the repayment price payable by the Company on repayment of such
Securities, and the obligation of the Company to pay the repayment price of
such Securities shall be satisfied and discharged to the extent such payment
is so paid by such purchasers.

                                 ARTICLE ELEVEN
                        CONCERNING THE SECURITYHOLDERS

         Section 11.01.  EVIDENCE OF ACTION TAKEN BY SECURITYHOLDERS.

         Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by a
specified percentage in principal amount of the Securityholders of any or all
series may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such specified percentage of
Securityholders in person or by agent duly appointed in writing. If
Securities of a series are issuable as Bearer Securities, any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders of such series
may, alternatively, be embodied in and evidenced by the record of Holders of
Securities of such series voting in favor thereof, either in person or by
proxies duly appointed in writing, at any meeting of Holders of Securities of
such series duly called and held in accordance with the provisions of
Sections 11.06 through 11.11, or a combination of such instruments such
record. Except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments or record or both are
delivered to the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments and any such record (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as
the "Act" of the Holders signing such instrument or instruments and so voting
at any such meeting. Proof of execution of any such instrument or of a
writing appointing any such agent, or of the holding by any Person of a
Security, be sufficient for any purpose of this Indenture and (subject to
Section 7.02) conclusive

                                       55

<PAGE>

in favor of the Trustee and the Company, if made in the manner provided in
Section 11.02. The record of any meeting of Holders of Securities shall be
proved in the manner provided in Section 11.11.

         Section 11.02.  PROOF OF EXECUTION OF INSTRUMENTS AND OF HOLDING OF
SECURITIES.

         The execution of any instrument by a Securityholder or his agent or
proxy may be proved in the following manner:

         (a)      The fact and date of the execution by any Holder of any
instrument may be proved by the certificate of any notary public or other
officer of any jurisdiction authorized to take acknowledgments of deeds or
administer oaths that the person executing such instruments acknowledged to
him the execution thereof, or by an affidavit of a witness to such execution
sworn to before any such notary or other such officer. Where such execution
is by or on behalf of any legal entity other than an individual, such
certificate or affidavit shall also constitute sufficient proof of the
authority of the person executing the same. The fact of the holding by any
Holder of a Bearer Security of any series, and the identifying number of such
Security and the date of his holding the same, may be proved by the
production of such Security or by a certificate executed by any trust
company, bank, banker or recognized securities dealer wherever situated
satisfactory to the Trustee, if such certificate shall be deemed by the
Trustee to be satisfactory. Each such certificate shall be dated and shall
state that on the date thereof a Security of such series bearing a specified
identifying number was deposited with or exhibited to such trust company,
bank, banker or recognized securities dealer by the person named in such
certificate. Any such certificate may be issued in respect of one or more
Bearer Securities of one or more series specified therein. The holding by the
person named in any such certificate of any Bearer Security or Securities of
any series specified therein shall be presumed to continue for a period of
one year from the date of such certificate unless at the time of any
determination of such holding (1) another certificate bearing a later date
issued in respect of the same Security or Securities shall be produced, or
(2) the Security or Securities of such series specified in such certificate
shall be produced by some other person, or (3) the Security or Securities of
such series specified in such certificate shall have ceased to be
Outstanding. Subject to Section 7.02, the fact and date of the execution of
any such instrument and the amount and numbers of Securities of any series
held by the person so executing such instrument and the amount and numbers of
any Security or Securities for such series may also be proven in accordance
with such reasonable rules and regulations as may be prescribed by the
Trustee for such series or in any other manner which the Trustee for such
series may deem sufficient.

         (b)      In the case of Registered Securities, the ownership of such
Securities shall be proved by the Security Register or by a certificate of
the Security Registrar.

         (c)      Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued
upon the registration of transfer thereof or in exchange therefor

                                       56

<PAGE>

or in lieu thereof in respect of anything done, omitted or suffered to be
done by the Trustee or the Company in reliance thereon, whether or not
notation of such action is made upon such Security.

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

         Section 11.03.  HOLDERS TO BE TREATED AS OWNERS.

         The Company, the Trustee and any agent of the Company or the Trustee
may deem and treat the person in whose name any Security shall be registered
upon the Security Register for such series as the absolute owner of such
Security (whether or not such Security shall be overdue and notwithstanding
any notation of ownership or other writing thereon) for the purpose of
receiving payment of or on account of the principal of and, subject to the
provisions of this Indenture, interest on and any Additional Amounts payable
in respect of such Security and for all other purposes; and neither the
Company nor the Trustee nor any agent of the Company or the Trustee shall be
affected by any notice to the contrary. The Company, the Trustee and any
agent of the Company or the Trustee may treat the Holder of any Bearer
Security and the Holder of any coupon as the absolute owner of such Bearer
Security or coupon (whether or not such Bearer Security or coupon shall be
overdue) for the purpose of receiving payment thereof or on account thereof
and for all other purposes and neither the Company, the Trustee, nor any
agent of the Company or the Trustee shall be affected by any notice to the
contrary. All such payments so made to any such person, or upon his order,
shall be valid, and, to the extent of the sum or sums so paid, effectual to
satisfy and discharge the liability for moneys payable upon any such Security
or coupon.

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

         Section 11.04.  SECURITIES OWNED BY COMPANY DEEMED NOT OUTSTANDING.

                                       57

<PAGE>

         In determining whether the Holders of the requisite aggregate
principal amount of Outstanding Securities of any or all series have
concurred in any direction, consent or waiver under this Indenture,
Securities which are owned by the Company or any other obligor on the
Securities with respect to which such determination is being made or by any
Affiliate of the Company or any such obligor shall be disregarded and deemed
not to be Outstanding for the purpose of any such determination, except that
for the purpose of determining whether the Trustee shall be protected in
relying on any such direction, consent or waiver only Securities which the
Trustee actually knows are so owned shall be so disregarded. Securities so
owned which have been pledged in good faith may be regarded as Outstanding if
the pledgee establishes to the satisfaction of the Trustee the pledgee's
right so to act with respect to such Securities and that the pledgee is not
the Company or any other obligor upon the Securities or any Affiliate of the
Company or any other obligor on the Securities. In case of a dispute as to
such right, the advice of counsel shall be full protection in respect of any
decision made by the Trustee in accordance with such advice. Upon request of
the Trustee, the Company shall furnish to the Trustee promptly an Officers'
Certificate listing and identifying all Securities, if any, known by the
Company to be owned or held by or for the account of any of the
above-described persons; and, subject to Section 7.02, the Trustee shall be
entitled to accept such Officers' Certificate as conclusive evidence of the
facts therein set forth and of the fact that all Securities not listed
therein are Outstanding for the purpose of such determination.

         Section 11.05.  RIGHT OF REVOCATION OF ACTION TAKEN.

         At any time prior to (but not after) the evidencing to the Trustee,
as provided in Section 11.01, of the taking of any action by the Holders of
the percentage in aggregate principal amount of the Securities of any or all
series, as the case may be, specified in this Indenture in connection with
such action, any Holder of a Security the serial number of which is shown by
the evidence to be included among the serial numbers of the Securities the
Holders of which have consented to such action may, by filing written notice
at the Corporate Trust Office and upon proof of holding as provided in this
Article, revoke such action so far as concerns such Security. Except as
aforesaid any such action taken by the Holder of any Security shall be
conclusive and binding upon such Holder and upon all future Holders and
owners of such Security and of any Securities issued in exchange or
substitution therefor or on registration of transfer thereof, irrespective of
whether or not any notation in regard thereto is made upon any such Security.
Any action taken by the Holders of the percentage in aggregate principal
amount of the Securities of any or all series, as the case may be, specified
in this Indenture in connection with such action shall be conclusively
binding upon the Company, the Trustee and the Holders of all the Securities
affected by such action.

         Section 11.06.  MEETINGS OF HOLDERS.

         A meeting of Holders of Securities of any series may be called at
any time and from time to time pursuant to this Section 11.06 to make, give
or take any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be made, given or taken
by Holders of Securities of such series.

         Section 11.07.  CALL, NOTICE AND PLACE OF MEETINGS.

         (a)      The Trustee may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 11.06, to be
held at such time and at such place in the Borough of Manhattan, The City of
New York, or in [Boston, Massachusetts] as the Trustee shall determine or,
with the approval of the Company, at any other place. Notice of every meeting
of Holders of Securities of any series, setting forth the time and the place
of such meeting and in general terms the action proposed to be taken at such
meeting, shall be given, in the manner provided in Section 13.02 not less
than 21 nor more than 180 days prior to the date fixed for the meeting.

         (b)      In case at any time the Company or the Holders of at least
10% in principal amount of the Outstanding Securities of any series shall
have requested the Trustee to call a meeting of the Holders of Securities of
such series for any purpose specified in Section 11.06, by written request
setting forth in reasonable detail the action proposed to be taken at the
meeting, and the Trustee shall not have made the first publication of the
notice of such meeting within 21 days after receipt of such request or shall
not thereafter proceed to cause the meeting to be held as provided herein,
the Company or the Holders of Securities of such series in the amount above
specified, as the case may be, may determine the time and the place in the
Borough of Manhattan, The City of New York, the City of Boston,
Massachusetts, or in such other place as shall be determined and approved by
the Company, for such meeting and may call such meeting for such purposes by
giving notice thereof as provided in Subsection (a) of this Section.

         Section 11.08.  PERSONS ENTITLED TO VOTE AT MEETINGS.

         To be entitled to vote at any meeting of Holders of any series, a
Person shall be (1) a Holder of one or more Outstanding Securities of such
series, or (2) a Person appointed by an instrument in writing as proxy for a
Holder or Holders of one or more Outstanding Securities of such series by
such Holder or Holders. The only Persons who shall be entitled to be present
or to speak at any meeting of Holders of Securities or any series shall be
the Persons entitled to vote at such meeting and their counsel, any
representatives of the Trustee and its counsel and any representatives of the
Company and its counsel.

         Section 11.09.  QUORUM; ACTION.

         The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series. In the absence of a quorum within 30
minutes of the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be
dissolved. In any other case, the meeting may be adjourned for a period
determined by the chairman of the meeting prior to the adjournment of such
meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period determined by the
chairman of the

                                       59

<PAGE>

meeting prior to the adjournment of such adjourned meeting. Notice of the
reconvening of any adjourned meeting shall be given as provided in Section
11.07(a), except that any such notice by publication need be given only once
not less than five days prior to the date on which the meeting is scheduled
to be reconvened. Notice of the reconvening of an adjourned meeting shall
state expressly the percentage, as provided above, of the principal amount of
the Outstanding Securities of such series which shall constitute a quorum.

         Any resolution presented to a meeting or adjourned meeting duly
reconvened at which a quorum is present as aforesaid may be adopted by the
affirmative vote of the Holders of a majority in principal amount of the
Outstanding Securities of that series; provided, however, that any resolution
with respect to any request, demand, authorization, direction, notice,
consent, waiver or other action which this Indenture expressly provides may
be made, given or taken by the Holders of a specified percentage, which is
less than a majority, in principal amount of the Outstanding Securities of a
series may be adopted at a meeting or an adjourned meeting duly reconvened
and at which a quorum is present as aforesaid by the affirmative vote of the
Holders of such specified percentage in principal amount of the Outstanding
Securities of that series.

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

         Section 11.10.  DETERMINATION OF VOTING RIGHTS; CONDUCT AND
ADJOURNMENT OF MEETINGS.

         (a)      Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities of a series in regard to proof of the
holding of Securities of such series and of the appointment of proxies and in
regard to the appointment and duties of inspectors of votes, the submission
and examination of proxies, certificates and other evidence of the right to
vote, and such other matters concerning the conduct of the meeting as it
shall deem appropriate. Except as otherwise permitted or required by any such
regulations, the holdings of Securities shall be proved in the manner
specified in Section 11.02 and the appointment of any proxy shall be provided
in the manner specified in Section 11.02 or by having the signature of the
person executing the proxy witnessed or guaranteed by any trust company, bank
or banker authorized by Section 11.02 to certify to the holding of Bearer
Securities. Such regulations may provide that written instruments appointing
proxies, regular on their face, may be presumed valid and genuine without the
proof specified in Section 11.02 or other proof.

         (b)      The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called
by the Company or by Holders of Securities as provided in Section 11.07(b),
in which case the Company or the Holders of Securities of the series calling
the meeting, as the case may be, shall in like manner appoint a temporary
chairman. A permanent chairman and a permanent secretary of the meeting shall
be

                                       60

<PAGE>

elected by vote of the Persons entitled to vote a majority in principal
amount of the Outstanding Securities of such series represented at the
meeting.

         (c)      At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect to
any Security challenged as not Outstanding and ruled by the chairman of the
meeting to be not Outstanding. The chairman of the meeting shall have no
right to vote, except as a Holder of Securities of such series or proxy.

         (d)      Any meeting of Holders of Securities of any series duly
called pursuant to Section 11.07 at which a quorum is present may be
adjourned from time to time by Persons entitled to vote a majority in
principal amount of the Outstanding Securities of such series represented at
the meeting; and the meeting may be held as so adjourned without further
notice.

         Section 11.11.  COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

         The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed signatures of the Holders of Securities of such series or their
representatives by proxy and the principal amounts and serial numbers of the
Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and
who shall make and file with the secretary of the meeting their verified
written reports in duplicate of all votes cast at the meeting. A record, at
least in duplicate, of the proceedings of each meeting of Holders of
Securities of any series shall be prepared by the secretary of the meeting
and there shall be attached to said record the original reports of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one
or more persons having knowledge of the facts setting forth a copy of the
notice of the meeting and showing that said notice was given as provided in
Section 11.07 and, if applicable, Section 11.09. Each copy shall be signed
and verified by the affidavits of the permanent chairman and secretary of the
meeting and one such copy shall be delivered to the Company, and another to
the Trustee to be preserved by the Trustee, the latter to have attached
thereto the ballots voted at the meeting. Any record so signed and verified
shall be conclusive evidence of the matters therein stated.

                                 ARTICLE TWELVE
                                 SINKING FUNDS

         Section 12.01.  APPLICABILITY OF ARTICLE.

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

                                       61

<PAGE>

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is referred to in this Article Twelve as a
"mandatory sinking fund payment," and any payment in excess of such minimum
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 12.02. Each
sinking fund payment shall be applied to the redemption of Securities of any
series as provided for by the terms of Securities of such series.

         Section 12.02.  SATISFACTION OF SINKING FUND PAYMENTS WITH
SECURITIES.

         The Company may, in satisfaction of all or any part of any sinking
fund payment with respect to the Securities of such series to be made
pursuant to the terms of such Securities as provided for by the terms of such
series (1) deliver Outstanding Securities of such series (other than any of
such Securities previously called for redemption or any of such Securities in
respect of which cash shall have been released to the Company), together in
the case of any Bearer Securities of such series with all unmatured coupons
appertaining thereto, and (2) apply as a credit Securities of such series
which have been redeemed either at the election of the Company pursuant to
the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of Securities have not been previously
so credited. Such Securities shall be received and credited for such purpose
by the Trustee at the Redemption Price specified in such Securities for
redemption through operation of the sinking fund and the amount of such
sinking fund payment shall be reduced accordingly. If as a result of the
delivery or credit of Securities of any series in lieu of cash payments
pursuant to this Section 12.02, the principal amount of Securities of such
series to be redeemed in order to exhaust the aforesaid cash payment shall be
less than $100,000, the Trustee need not call Securities of such series for
redemption, except upon Company request, and such cash payment shall be held
by the Trustee or a Paying Agent for Securities of that series and applied to
the next succeeding sinking fund payment, provided, however, that the Trustee
or such Paying Agent shall at the request of the Company from time to time
pay over and deliver to the Company any cash payment so being held by the
Trustee or such Paying Agent upon delivery by the Company to the Trustee of
Securities purchased by the Company having an unpaid principal amount equal
to the cash payment requested to be released to the Company.

         Section 12.03.  REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for
any series of Securities, the Company will deliver to the Trustee an
Officers' Certificate specifying the amount of the next ensuing 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 12.02, and the
optional amount, if any, to be added in cash to the next ensuing mandatory
sinking

                                       62

<PAGE>

fund payment, and will also deliver to the Trustee any Securities to be so
credited and not theretofore delivered. If such Officers' Certificate shall
specify an optional amount to be added in cash to the next ensuing mandatory
sinking fund payment, the Company shall thereupon be obligated to pay the
amount therein specified.

         Not less than 30 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 3.03 and cause notice of the
redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 3.04. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in
the manner stated in Sections 3.05 and 3.06.

                                ARTICLE THIRTEEN

         Re: Sierra Pacific Resources

         The Company or the Trustee by notice to the others may designate
additional or different addresses for subsequent notices or communications.

         Any notice or communication mailed to a Holder of a Registered
Security shall be mailed to him by first class mail at his address as it
appears on the Security Register and shall be sufficiently given to him if so
mailed within the time prescribed. Failure to mail a notice or communication
to a Holder of any Registered Security or any defect in it shall not affect
its sufficiency with respect to other Securityholders. If a notice or
communication is mailed in the manner provided above, it is duly given,
whether or not the addressee receives it.

         In case, by reason of the suspension of regular mail service or by
reason of any other cause, it shall be impossible to mail any notice as
required by this Indenture, then such method of notification as shall be made
with the approval of the Trustee shall constitute a sufficient mailing of
such notice.

         Any notice required or permitted to be given to a Holder of Bearer
Securities of any series shall be deemed to be properly given if such notice
is published in an Authorized Newspaper on two separate days within the time
prescribed.

         In case, by reason of the suspension of publication of any
Authorized Newspaper or Authorized Newspapers or by reason of any other
cause, it shall be impracticable to publish any notice to Holders of Bearer
Securities as provided above, then such notification to Holders of Bearer
Securities as shall be given with the approval of the Trustee shall
constitute sufficient notice to such Holders for every purpose hereunder.
Neither failure to give notice by publication to Holders of Bearer Securities
as provided above, nor any defect in any notice so published, shall affect
the sufficiency of any notice mailed to Holders of Registered Securities as
provided above.

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

                                       64

         Any request, demand, authorization, direction, notice, consent,

have the protection of TIA Section 312(c).

         Section 13.04.  CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.

         Upon any request or application by the Company to the Trustee to
take any action under this Indenture (except that, in the case of any request
or application as to which the furnishing of such documents is specifically
required by any provision of this Indenture relating to such particular
request or application, no additional certificate or opinion need be
furnished), the Company shall furnish to the Trustee:

                  (1)      an Officers' Certificate stating that, in the
opinion of the signers, all conditions precedent, if any, provided for in
this Indenture relating to the proposed action have been complied with; and

                  (2)      an Opinion of Counsel stating that, in the opinion
of such counsel, all such conditions precedent have been complied with.

         Section 13.05.  STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.

         Each certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

                  (1)      a statement that the Person making such
certificate or opinion has read such covenant or condition and the
definitions relating thereto;

                  (2)      a brief statement as to the nature and scope of
the examination or investigation upon which the statements or opinions
contained in such certificate or opinion are based;

                  (3)      a statement that, in the opinion of such Person,
he has made such examination or investigation as is necessary to enable him
to express an informed opinion as to whether or not such covenant or
condition has been complied with; and

                                       65

                  (4)      a statement as to whether or not, in the opinion
of such Person, such condition or covenant has been complied with.

         Section 13.06.  WHEN TREASURY SECURITIES DISREGARDED.

         In determining whether the Holders of the required principal amount
of Securities or a series thereof have concurred in any direction, waiver or
consent, Securities owned by the Company or any other obligor upon the
Securities or by any Affiliate of the Company or such obligor shall be
disregarded, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Securities which the Trustee actually knows are so owned shall be so
disregarded. Securities so owned which have been pledged in good faith shall
not be disregarded if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with respect to the Securities and that
the pledgee is not the Company or any other obligor upon the Securities or
any Affiliate of the Company or such obligor.

         Section 13.07.  LEGAL HOLIDAYS.

         A "Legal Holiday", except as otherwise provided in the form of
Security of any particular series pursuant to the provisions of this
Indenture, with respect to any Place of Payment means a Saturday, a Sunday or
a day on which banking institutions or trust companies in that Place of
Payment are not required to be open. Except as provided otherwise in the
applicable Security, if a payment date with respect to such payment is a
Legal Holiday at any Place of Payment, payment due on such Security with
respect to such Security may be made at such place on the next succeeding day
that is not a Legal Holiday, and no interest shall accrue with respect to
such payment for the intervening period.

         Section 13.08.  GOVERNING LAW.

         The laws of the State of New York applicable to contracts made and
performed in said state shall govern this Indenture and the Securities and
coupons, without regard to choice of law principles. Unless the form of
Security provides otherwise, all money or dollar amounts expressed herein or
in the Securities refer to United States dollars.

         Section 13.09.  NO ADVERSE INTERPRETATION OF OTHER AGREEMENTS.

         This Indenture may not be used to interpret another indenture, loan
or debt agreement of the Company or a Subsidiary. Any such indenture, loan or
debt agreement may not be used to interpret this Indenture.

         All agreements of the Company in this Indenture and the Securities
shall bind its successor and assigns, whether so expressed or not. All
agreements of the Trustee in this Indenture shall bind its successor.

         Section 13.11.  DUPLICATE ORIGINALS.

         The parties may sign any number of copies of this Indenture. Each
signed copy shall be an original, but all of them together represent the same
agreement.

         Section 13.12.  SECURITIES IN FOREIGN CURRENCIES.

         Wherever this Indenture provides for any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same currency, or any
distribution to Holders of Securities, in the absence of any provision to the
contrary in the form of Security of any particular series, any amount in
respect of any Security denominated in a currency other than United States
dollars shall be treated for any such action, determination or distribution
as that amount of United States dollars that could be obtained for such
amount on such reasonable basis of exchange and as of such date as the
Company may specify in a written notice to the Trustee, or in the absence of
such notice, as the Trustee may determine.

                              8 3/4% NOTES DUE 2005

         Sierra Pacific Resources, a corporation duly organized and existing
under the laws of the State of Nevada (hereinafter called the "Company",
which term includes any successor corporation under the Indenture referred to
below), for value received, hereby promises to pay to Cede & Co., as the
nominee of The Depository Trust Company, or registered assigns, the principal
sum of Three Hundred Million Dollars ($300,000,000) on May 15, 2005 and to
pay interest thereon from the most recent interest payment date to which
interest has been paid or duly provided for, payable semiannually on May 15
and November 15 in each year (each, an "Interest Payment Date"), commencing
November 15, 2000, at the rate of 8 3/4% per annum, until the principal
hereof is paid or duly made available for payment. Interest on this Note
shall be calculated on the basis of a 360-day year of twelve 30-day months.
If any Interest Payment Date or maturity date falls on a day that is not a
Business Day, the required payment shall be made on the next Business Day as
if it were made on the date such payment was due and no interest shall

<PAGE>

accrue on the amount so payable for the period from and after such Interest
Payment Date or maturity date, as the case may be, to such next Business Day.
The interest so payable and punctually paid or duly provided for on any
Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Note (or one or more predecessor securities) is
registered, at the close of business on the regular record date for such
interest, which shall be May 1 or November 1 (whether or not a Business Day),
as the case may be, next preceding such Interest Payment Date. Any such
interest which is payable, but is not punctually paid or duly provided for,
on any Interest Payment Date shall forthwith cease to be payable to the
registered Holder hereof on the relevant regular record date by virtue of
having been such Holder, and may be paid to the Person in whose name this
Note (or one or more predecessor securities) is registered at the close of
business on a subsequent special record date (which shall be at least ten
days before the payment date) for the payment of such defaulted interest to
be fixed by the Company, notice whereof shall be given to the Holders of
Notes of this series not less than 15 days prior to such Special Record Date,
or may be paid at any time in any other lawful manner not inconsistent with
the requirements of any securities exchange on which the Notes may be listed,
and upon such notice as may be required by such exchange.

         Payment of the principal of and the interest on this Note will be
made at the office or agency of the Company maintained for that purpose in
the Borough of Manhattan, The City of New York, in such coin or currency of
the United States of America as at the time of payment is legal tender for
payment of public and private debts; provided, however, that, at the option
of the Company, interest may be paid by check mailed to the address of the
Person entitled thereto as such address shall appear in the Security
Register; provided, further, that payment to DTC or any successor depository
may be made by wire transfer to the account designated by DTC or such
successor depository in writing.

         This Note is one of a duly authorized issue of securities of the
Company (herein called the "Notes") and to be issued in one or more series
under an Indenture, dated as of May 1, 2000 (herein called, together with all
indentures supplemental thereto, the "Indenture"), between the Company and
The Bank of New York, as Trustee (herein called the "Trustee", which term
includes any successor trustee under the Indenture), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement
of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders of the Notes, and the
term upon which the Notes are, and are to be, authenticated and delivered.
This Note is one of the series designated on the face hereof, initially
limited (subject to exceptions provided in the Indenture) to the aggregate
principal amount specified in the Officers' Certificate dated May 9, 2000
(the "Officers' Certificate"), establishing the terms of the Notes pursuant
to the Indenture.

         If an Event of Default with respect to the Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

         The Indenture contains provisions permitting, with certain
exceptions as therein provided, the amendment thereof and the modification of
the rights and obligations of the Company and the rights of the Holders of
the Securities of each series issued under the Indenture at any time by the
Company and the Trustee with the written consent of the Holders of not less
than a majority

                                       2

<PAGE>

in aggregate principal amount of the Securities at the time Outstanding of
each series affected thereby. The Indenture further provides that without the
consent of any Holder the Company and the Trustee may amend or supplement the
Indenture or Notes to, among other things, cure any ambiguity, defect or
inconsistency, provided that no such action shall adversely affect the
interest of the Holders. The Indenture also contains provisions permitting
the Holders of specified percentages in aggregate principal amount of the
Securities of any series at the time outstanding, on behalf of the Holders of
all Securities of such series, or the Holders of at least a majority in
principal amount of all the Outstanding Securities voting as one class, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Note and of any Notes
issued upon the registration or transfer hereof or in exchange herefor or in
lieu hereof, whether or not notation of such consent or waiver is made upon
this Note.

         This Note is not subject to any sinking fund and, except as provided
below, is not redeemable or prepayable prior to its maturity date. At the
Company's option, the Notes may be redeemed, in whole or in part, at any time
or from time to time, at a redemption price calculated as set forth below
together with accrued interest thereon at the applicable rate payable to the
date of redemption, upon written notice given not more than 60 days nor less
than 30 days prior to such redemption date. The redemption price shall be the
greater of:

     (1)          100% of the principal amount of the Notes to be redeemed, and

     (2)          the sum of the present values of the remaining scheduled
                  payments of principal and interest on the Notes to be redeemed
                  discounted to the date of redemption on a semi-annual basis
                  (assuming a 360-day year consisting of twelve 30-day months)
                  at the applicable Treasury Rate, plus 25 basis points.

         For purposes of calculating the above redemption price, the

                           the remaining term of the notes to be redeemed that
                           would be utilized, at the time of selection and in
                           accordance with customary financial practice, in
                           pricing new issues of corporate debt securities of
