    Sierra Pacific Resources engages primarily in the energy business through
several subsidiaries. Our two largest subsidiaries, Nevada Power Company and
Sierra Pacific Power Company, are regulated public utilities. Nevada Power
Company provides electricity to the City of Las Vegas and the surrounding area
in southern Nevada. Sierra Pacific Power Company provides electricity to
western, central and northeastern Nevada, including the cities of Reno, Sparks,
Carson City and Elko, and to the Lake Tahoe area of California. Sierra Pacific
Power Company also provides natural gas and water services to the cities of Reno
and Sparks and surrounding areas. Sierra Pacific Resources and Nevada Power
Company merged in June 1999 and Nevada Power Company became a subsidiary of
Sierra Pacific Resources. As part of the merger, Sierra Pacific Power Company
and Nevada Power Company agreed to sell their electric generating assets.

    Additional information regarding the merger is contained in our Registration
Statement on Form S-4 (file number 333-62895).

    The principal executive office of Sierra Pacific Resources is P.O. Box
301500 (6100 Neil Road), Reno, Nevada 89520-3150, and the telephone number is
(775) 834-4011.

    In this prospectus, "Sierra Pacific," "we," "us" and "our" refer
specifically to Sierra Pacific Resources, the holding company.

                                   THE TRUSTS

    Sierra Pacific Capital Trust I and Sierra Pacific Capital Trust II are
statutory business trusts created under Delaware law. They were created pursuant
to declarations of trust and by the filing of a Certificate of Trust with the
Secretary of State of the State of Delaware on June   , 1999. Each declaration
of trust will be amended and restated in its entirety substantially in the forms
filed as an exhibit to the registration statement of which this prospectus is a
part. Each declaration will be qualified as an indenture under the Trust
Indenture Act of 1939, as amended. When the preferred securities of each trust
are issued, the purchasers of those securities will own all of the preferred
securities of each trust. See "Description of the Preferred Securities." We will
directly or indirectly acquire all of the trusts' issued and outstanding common
securities, which will be in an aggregate liquidation amount equal to at least
3% of the total capital of each trust. The trusts will use all of the proceeds
from the issuance of their preferred securities and common securities
(collectively, the "Trust Securities") to purchase subordinated debt securities
issued by Sierra Pacific. The only assets of each trust are subordinated debt
securities issued by Sierra Pacific. Each trust exists for the exclusive
purposes of

    - issuing its Trust Securities representing undivided beneficial interests
      in the assets of the trust;

    - investing the gross proceeds of the sale of its Trust Securities in
      subordinated debt securities issued by Sierra Pacific; and

    - engaging in only those other activities necessary or incidental to the
      foregoing purposes.

    Each trust has a term of approximately 55 years, but may be dissolved
earlier as provided in its declaration.

    Sierra Pacific has appointed the following four trustees to conduct each
trust's business and affairs:

    - two officers of Sierra Pacific (the "administrative trustees");

    - The Bank of New York (the "property trustee"); and

    - The Bank of New York (Delaware) (the "Delaware trustee").

                                       1
<PAGE>
    The property trustee will hold title to the subordinated debt securities of
Sierra Pacific purchased by each trust for the benefit of each trust and the
holders of the Trust Securities. As long as the subordinated debt securities are
held by a trust, the property trustee will have the power to exercise all
rights, powers, and privileges of a holder of subordinated debt securities under
the indenture to be entered into by and between Sierra Pacific and The Bank of
New York, as indenture trustee. In addition, the property trustee will maintain
exclusive control of a segregated non-interest bearing bank account for each
trust (the "property trustee accounts") to hold all payments made in respect of
the subordinated debt securities for the benefit of the holders of the Trust
Securities of each trust.

    Sierra Pacific, as the holder of all the common securities of each trust,
will have the right to appoint, remove or replace any trustee (subject to the
limitations shown in the declarations) and to increase or decrease the number of
trustees of each trust, provided that the number of trustees of each trust shall
be at least three. Sierra Pacific will pay all fees, expenses, debts and
obligations (other than with respect to the Trust Securities) related to each
trust and the offering of the Trust Securities by each trust.

    The rights of the holders of the preferred securities of each trust,
including economic rights, rights to information and voting rights, are
contained in its declaration and in the Delaware Business Trust Act. See
"Description of the Preferred Securities of the Trusts." The declarations also
incorporate by reference the terms of the Trust Indenture Act.

    The principal executive office of each trust is P.O. Box 30150 (6100 Neil
Road), Reno, Nevada 89520-3150. The telephone number of each trust is (775)
834-4001.

                                USE OF PROCEEDS

    We intend to use the net proceeds from the sale of our debt securities for
general corporate purposes, unless otherwise specified in the prospectus
supplement or term sheet relating to a specific issue of debt securities.
General corporate purposes may include financing the activities of Sierra
Pacific's subsidiaries, financing our assets and those of our subsidiaries,
refinancing our existing borrowings, and financing acquisitions. Until we use
the net proceeds from the sale of any of our securities for general corporate
purposes, we will use the net proceeds to reduce our short-term indebtedness or
for temporary investments. We expect that we will, on a recurrent basis, engage
in additional financings as the need arises to finance our growth, through
acquisitions or otherwise, or to refinance our existing borrowings.

    We currently intend to use the net proceeds from the sale of our debt
securities to cover a portion of the cash consideration required in connection
with our merger with Nevada Power Company and to repay bank indebtedness
incurred in connection with the Merger. The specific allocations of the proceeds
we receive from the sale of our securities will be described in the prospectus
supplement relating thereto.

    Each trust will use all proceeds received from the sale of its Trust
Securities and common securities to purchase subordinated debt securities issued
by us.

              CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES AND
           EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED DIVIDENDS

    The following table sets forth our consolidated ratios of earnings to
combined fixed charges and preferred dividends. The ratios shown in the table
are both the historical ratios and the pro forma combined ratios showing the
effect of the merger between Sierra Pacific and Nevada Power Company. As a
result of the merger between Sierra Pacific and Nevada Power Company, which has
been treated for accounting purposes as a reverse acquisition with Nevada Power
being the acquiror, the historical ratios are those of Nevada Power Company. The
pro forma combined ratios assume that the merger occurred at the beginning of
the applicable period.

    For the purpose of calculating the ratio of earnings to fixed charges,
"earnings" represent the aggregate of net income, taxes on income and fixed
charges (less capitalized interest and preference security dividend requirements
of consolidated subsidiaries). Earnings used in the calculation of the ratios of
earnings to fixed charges include the allowance for funds used during
construction. "Fixed charges" represent interest on short-term and long-term
debt, the interest portion on capital leases representing that portion of rental
expense deemed to be attributable to interest, and the tax-effected preference
security dividend requirements of consolidated subsidiaries.

                       DESCRIPTION OF THE DEBT SECURITIES

GENERAL

    From time to time we may issue debt securities in one or more series as
either senior securities ("senior debt securities") or subordinated securities
("subordinated debt securities"). The term "debt securities" refers to both the
senior debt securities and the subordinated debt securities. Below is a
description of the general terms of the debt securities. The particular terms of
a series of debt securities will be described in a prospectus supplement.

    Senior debt securities will be issued under an indenture, as supplemented
from time to time (the "senior indenture"), between Sierra Pacific and The Bank
of New York, as trustee (the "senior indenture trustee"). Unless specified in a
prospectus supplement, subordinated debt securities will be issued under an
indenture, as supplemented from time to time (the "subordinated indenture"),
between Sierra Pacific and The Bank of New York, as trustee (the "subordinated
indenture trustee"). The term "indentures" refers to the senior indenture and
the subordinated indenture. Each of the indentures will be subject to and
governed by the Trust Indenture Act of 1939.

    The indentures do not limit the amount of debt securities that we may issue,
nor do they limit us or our subsidiaries from issuing any other unsecured debt.

    The senior debt securities will rank equally with all of our unsecured and
unsubordinated debt. The subordinated debt securities will be unsecured and will
be subordinate and junior in priority of payment to our other indebtedness to
the extent described in a prospectus supplement. As a holding company, our cash
flows and our ability to service our debt are dependent on the cash flows of our
subsidiaries. Our subsidiaries are separate and distinct legal entities and will
have no obligation to pay any amounts due under the debt securities. In
addition, our two largest subsidiaries, Nevada Power and Sierra Pacific Power,
are subject to regulation by state utility commissions which may impose
limitations

                                       3
<PAGE>
on the rate of return on equity or otherwise impact the amount of dividends
which may be paid by those companies. Moreover, the articles of incorporation of
both Nevada Power Company and Sierra Pacific Power Company contain restrictions
on the payment of dividends on that subsidiary's common stock if there is
currently a default in the payment of dividends on that company's preferred
stock. Similarly, the terms of the bank credit facilities of Nevada Power
Company and Sierra Pacific Power Company prohibit the payment of dividends on
each company's common stock if that company is in default under its credit
facility. As a result, the debt securities will be effectively subordinated to
all indebtedness and other liabilities of our subsidiaries.

TERMS OF THE DEBT SECURITIES

    Each prospectus supplement will describe the terms of a series of debt
securities, including:

    - the title and series designation;

    - the aggregate principal amount and authorized denominations of the debt
      securities;

    - the percentage of principal amount at which the debt securities will be
      issued;

    - the stated maturity date;

    - any fixed or variable interest rates or rates per annum;

    - the times at which any interest will be payable, the date or dates from
      which interest will accrue and the regular record dates for interest
      payments or the method for determining those dates;

    - the principal amount payable, whether at maturity or upon earlier
      acceleration, and whether the principal amount will be determined with
      reference to an index, formula or other method;

    - whether the debt securities are denominated or payable in United States
      dollars;

    - any sinking fund requirements;

    - any terms under which Sierra Pacific can redeem the debt securities;

    - any terms for repayment of principal amount at the option of the holder;

    - whether and under what circumstances Sierra Pacific will pay additional
      amounts ("Additional Amounts") under any debt securities to a person who
      is not a U.S. person for specified taxes, assessments or other
      governmental charges and whether Sierra Pacific has the option to redeem
      the affected debt securities rather than pay any Additional Amounts;

    - the form in which Sierra Pacific will issue the debt securities, whether
      registered, bearer or both, and any restrictions applicable to the
      exchange of one form for another and to the offer, sale and delivery of
      the debt securities in either form;

    - whether the debt securities will be issued in global form, and any terms
      and conditions under which interests the debt securities in global form
      may be exchanged for individual debt securities;

    - the minimum denominations;

    - the defeasance provisions, if any, that apply to the debt securities
      (other than those described herein);

    - the person to whom any interest on a registered security is payable, if
      that person is not the registered owner of the debt securities, or the
      manner in which any interest is payable on a bearer security if other than
      upon presentation of the coupons pertaining thereto, as the case may be;

                                       4
<PAGE>
    - any events of default or covenants not contained in the applicable
      indenture; and

    - any other specific terms of the debt securities which are not inconsistent
      with the provisions of the applicable indenture.

    Prospective purchasers of debt securities should be aware that special U.S.
Federal income tax, accounting and other considerations may be applicable to
instruments such as the debt securities. The prospectus supplement relating to
an issue of debt securities will describe these considerations, if applicable.

    The provisions of the indentures permit Sierra Pacific, without the consent
of holders of any debt securities, to issue additional debt securities with
terms different from those of debt securities previously issued and to reopen a
previous issue of a series of debt securities and issue additional debt
securities of that series.

    Sierra Pacific will pay or deliver principal and any premium, Additional
Amounts, and interest in the manner, at the places and subject to the
restrictions described in the applicable indenture, the debt securities and the
applicable prospectus supplement.

CONSOLIDATION, MERGER OR SALE

    The indentures permit Sierra Pacific to merge or consolidate, or sell,
convey, transfer or otherwise dispose of all or substantially all of its assets,
if the following conditions are satisfied:

    - no event of default would occur under the indentures as a result of such
      transaction;

    - any successor or acquiror assumes all of the obligations of Sierra Pacific
      under the indentures and the debt securities; and

    - the successor or acquiror is organized and existing under the laws of the
      United States of America or of any U.S. state.

    If a series of subordinated debt securities is held by a trust, any
transaction referred to above would also have to be permitted under and not
result in any breach of violation of the applicable trust agreement and
guarantee.

MODIFICATION OF INDENTURES; WAIVER

    Each indenture may be modified or amended by Sierra Pacific and the
applicable trustee without the consent of any holders with respect to matters
contained in the indenture, including:

    - curing any ambiguity or correcting any inconsistency in the indenture;

    - to provide for uncertificated debt securities;

    - to establish the form or terms of debt securities of any series; or

    - to make any change that does not materially adversely affect the rights of
      any holder of a debt security.

    In addition, under each indenture, Sierra Pacific and the applicable trustee
may change the rights of holders of a series of debt securities with the written
consent of the holders of at least a majority in aggregate principal amount of
the outstanding debt securities of each affected series. However, the following
changes may be made only with the consent of each holder of any outstanding debt
securities affected:

    - changing the stated maturity of those debt securities;

    - reducing the principal amount of a discount security payable upon
      declaration of acceleration;

                                       5
<PAGE>
    - reducing the principal amount, reducing the rate of or extending the time
      of payment of interest, or reducing any premium payable upon redemption;

    - changing the place or currency of any payment of principal or interest;

    - impairing the right to bring a suit for the enforcement of any payment on
      or with respect to those debt securities; and

    - modifying any of the foregoing requirements or reducing the percentage of
      holders of debt securities required to consent to any amendment or waiver
      of any covenant or past default.

    If a series of subordinated debt securities is held by a trust, no
modification of the subordinated indenture may occur without the prior consent
of the holders of at least a majority of the aggregate liquidation preference of
the trust's preferred securities.

    The holders of at least a majority in principal amount of the outstanding
debt securities of any series may, with respect to that series, waive past
defaults under the applicable indenture and waive compliance by Sierra Pacific
with the provisions of that indenture, except as described under "Events of
Default."

EVENTS OF DEFAULT

    Each of the following will be an Event of Default with respect to each
series of debt securities issued under each indenture:

    - default in the payment of any principal or premium, when due (except when
      the failure to make payment when due results from mistake, oversight or
      transfer difficulties and does not continue for more than three business
      days);

    - default in the payment of interest or Additional Amounts and the
      continuance of that default for a period of 30 days;

    - default with respect to any obligation to make payments to a sinking fund,
      when due (except when the failure to make payment when due results from
      mistake, oversight or transfer difficulties and does not continue for more
      than three business days);

    - default in the performance or breach of any other obligation contained in
      the applicable indenture or in the debt securities with respect to that
      series and continuance of the default for a period of 60 days after
      written notice as provided in the applicable indenture;

    - specified events of bankruptcy, insolvency or reorganization of Sierra
      Pacific which remain in effect for a period of sixty consecutive days; or

    - any other Event of Default provided in the applicable prospectus
      supplement.

    If a series of subordinated debt securities is held by a trust, it would
also be an event of default if the trust dissolves, winds up or terminates,
except in connection with:

    - the distribution of the subordinated debt securities to holders of
      preferred and common securities of the trust;

    - the redemption of all of the preferred and common securities of the trust;
      or

    - mergers, consolidations, conversions or amalgamations permitted by the
      declaration of trust.

    If an Event of Default with respect to debt securities of any series occurs
and is continuing, the applicable trustee or the holders of at least 25% in
principal amount of the outstanding debt securities of that series may declare
all amounts due and payable or deliverable immediately. Holders of a majority in
principal amount of the outstanding debt securities of an affected series may
rescind and

                                       6
<PAGE>
annul a declaration of acceleration if Sierra Pacific deposits with the trustee
enough money to cover all overdue amounts on the outstanding debt securities
other than the amounts that would be due as a result of the acceleration.

    Holders of a majority in principal amount of the outstanding debt securities
of an affected series (or if subordinated debt securities of an affected series
are held by a trust, the holders of at least a majority in liquidation amount of
the trust's preferred securities) may waive any past default or event of default
of that series, except defaults or events of default regarding covenants that
cannot be modified or amended without the consent of each holder of any
outstanding debt securities affected (see "--Modification of Indentures; Waiver"
below).

    Holders of debt securities may not enforce the applicable indentures or the
relevant debt securities except as set forth in the applicable indenture. The
trustee under an indenture may refuse to enforce the indenture on the applicable
debt securities unless it receives indemnification satisfactory to it. Subject
to limitations contained in the indentures, holders of a majority in principal
amount of debt securities issued under an indenture may direct the trustee in
its exercise of any power granted to it under the indenture.

    If the subordinated debt securities of any series are held by a trust, and a
"declaration event of default" (as defined under "Description of Preferred
Securities of the Trusts--Declaration Events of Default") has occurred and is
attributable to the failure of Sierra Pacific to pay principal, premium, if any,
or interest on, those subordinated debt securities, then each holder of the
preferred securities of that trust may sue Sierra Pacific, or seek other
remedies to force payment to that holder of an amount equal to the aggregate
liquidation amount of the preferred securities held by that holder.

SPECIAL TERMS RELATING TO THE SUBORDINATED DEBT SECURITIES

    SUBORDINATION.

    If Sierra Pacific's assets are distributed upon dissolution, winding up,
liquidation or reorganization, payments on subordinated debt securities will be
subordinated, to the extent provided in the subordinated indenture, to the prior
payment in full of all senior indebtedness, including senior debt securities. If
the maturity of any subordinated debt securities is accelerated, the holders of
all senior indebtedness outstanding at the time of acceleration will be entitled
to receive payment in full of all amounts due on the senior indebtedness before
the holders of subordinated debt securities will be entitled to receive or
retain any payment on the subordinated debt securities. However, the obligation
of Sierra Pacific to make payments on the subordinated debt securities will not
be affected in any other manner. Sierra Pacific may not make any payment on
subordinated debt securities at any time when there is a default in the payment
or delivery of any amounts due on any senior indebtedness, including payment of
any sinking fund. If, while there is a default on senior indebtedness, any
payment is received by the subordinated indenture trustee under the subordinated
indenture or the holders of any subordinated debt securities before all senior
indebtedness has been paid in full, that payment or distribution must be paid
over to the holders of the unpaid senior indebtedness or applied to the
repayment of the unpaid senior indebtedness. Holders of subordinated debt
securities will be subrogated to the rights of the holders of senior
indebtedness to the extent of payments made on senior indebtedness upon any
distribution of assets in any proceeding in respect of subordinated debt
securities.

    REDEMPTION.

    Unless otherwise indicated in the applicable prospectus supplement,
subordinated debt securities will not be subject to any sinking fund.

                                       7
<PAGE>
    Unless otherwise indicated in the applicable prospectus supplement, Sierra
Pacific may, at its option, redeem the subordinated debt securities of any
series in whole at any time or in part from time to time. Except as otherwise
specified in the applicable prospectus supplement, the redemption price will be
equal to the principal and any accrued and unpaid interest on the subordinated
debt securities to the redemption date.

    Except as otherwise specified in the applicable prospectus supplement, if a
subordinated debt security tax event (as defined below) shall occur and be
continuing, Sierra Pacific may, at its option, redeem the subordinated debt
securities in whole at any time within 90 days of the occurrence of the
Subordinated Debt Security Tax Event, at a redemption price equal to 100% of the
principal amount of the subordinated debt securities then outstanding plus
accrued and unpaid interest to the date fixed for redemption.

    "Subordinated Debt Security Tax Event" means the receipt by Sierra Pacific
of an opinion of counsel experienced in such matters to the effect that:

    - as a result of any amendment to, or change (including any announced
      prospective change) in, the laws (or any regulations thereunder) of the
      United States or any political subdivision or taxing authority thereof or
      therein, or

    - as a result of any official administrative pronouncement or judicial
      decision interpreting or applying the laws or regulations, which amendment
      or change is effective or which pronouncement or decision is announced on
      or after the date of issuance of the applicable series of subordinated
      debt securities, there is more than an insubstantial risk that interest
      payable by Sierra Pacific on the series of subordinated debt securities is
      not, or within 90 days of the date of the opinion will not be, deductible
      by Sierra Pacific, in whole or in part, for United States Federal income
      tax purposes.

    Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of subordinated debt
securities to be redeemed at its registered address. Unless Sierra Pacific
defaults in payment of the redemption price, on and after the redemption date
interest ceases to accrue on the subordinated debt securities or portions
thereof called for redemption.

    If this prospectus is being delivered with the offering of a series of
subordinated debt securities, the accompanying prospectus supplement will show
the approximate amount of senior indebtedness outstanding as of a recent date.

    OPTION TO EXTEND INTEREST PAYMENT DATE

    If provided in the applicable prospectus supplement, Sierra Pacific will
have the right at any time and from time to time during the term of any
subordinated debt securities to defer payment of interest for the number of
consecutive interest payment periods as may be specified in the applicable
prospective supplement. No extension period may extend beyond the stated
maturity date of subordinated debt securities. United States federal income tax
consequences and special considerations applicable to the extension of interest
payment dates will be described in the applicable prospectus supplement.

<PAGE>
    RESTRICTIONS ON CERTAIN PAYMENTS

    Unless otherwise specified in the applicable Prospectus Supplement, Sierra
Pacific will covenant, as to each series of subordinated debt securities, that
it will not, and will not permit any of its subsidiaries to:

    - declare or pay any dividends or distributions on, or redeem, purchase,
      acquire, or make a liquidation payment with respect to, any of Sierra
      Pacific's capital stock, or

    - make any payment of principal, interest or premium, if any, on or repay,
      repurchase or redeem any debt securities of Sierra Pacific (including
      other subordinated debt securities) that rank PARI PASSU with or junior in
      interest to the subordinated debt securities of any subsidiary or any
      guarantee payments with respect to any guarantee by Sierra Pacific of the
      debt securities of any subsidiary, if such guarantee ranks PARI PASSU or
      junior in interest to the subordinated debt securities;

    if at that time:

    - there shall have occurred any event which Sierra Pacific has actual
      knowledge that with the giving of notice or the lapse of time, or both
      would cause an Event of Default under the subordinated indenture;

    - there is a default by Sierra Pacific relating to its payment of any
      obligations under a preferred securities guarantee; or

    - Sierra Pacific shall have given notice of its selection of an extension
      period under the subordinated indenture and shall not have rescinded the
      notice, or the extention period shall be continuing.

    The above covenants do not restrict the payment of dividends by Sierra
Pacific Power Company or Nevada Power Company on their capital stock, nor do
they restrict Sierra Pacific from paying:

    - dividends or distributions in common stock,

    - redemptions or purchases of any rights pursuant to any rights plan adopted
      by Sierra Pacific, or any successor to the rights plan, and the
      declaration of a dividend of the rights or the issuance of stock under the
      plan in the future,

    - payments under any guarantee, and

    - purchases of common stock related to the issuance of common stock under
      any of Sierra Pacific's benefit plans for its directors, officers or
      employees or under Sierra Pacific's Common Stock Investment Plan or any
      successor plan.

    OPTION TO CHANGE STATED MATURITY DATE

    If provided in the applicable prospectus supplement, Sierra Pacific shall
have the right to:

    - change the maturity date of a series of subordinated debt securities and
      exchange those subordinated debt securities for preferred securities of
      the trust upon liquidation of the trust; or

    - extend the stated maturity of the subordinated debt securities;

provided that at the time of any change in the maturity date:

    - Sierra Pacific is not in bankruptcy, insolvent or in liquidation;

    - Sierra Pacific is not in default on the principal or interest on the
      subordinated debt securities;

    - the applicable trust is not in arrears on payments of distributions on its
      preferred securities;

    - the subordinated debt securities are rated not less than BBB--by Standard
      & Poor's Rating Services on Baa3 by Moody's Investors Service, Inc.; and

                                       9
<PAGE>
    - the extended maturity date is no later than the 49th anniversary of the
      initial issuance of the preferred securities of the applicable trust.

    In addition, if Sierra Pacific exercises its right to liquidate the trust
and exchange subordinated debt securities for preferred securities of the trust,
any changed stated maturity date cannot be earlier than five years after the
issuance of the preferred securities and no later than thirty years after the
issuance of the preferred securities.

SPECIAL TERMS RELATING TO THE SENIOR DEBT SECURITIES

    LIMITATIONS UPON LIENS ON STOCK OF RESTRICTED SUBSIDIARIES.

    Sierra Pacific will not, nor will it permit any "restricted subsidiary" to,
create, issue, assume, guarantee or permit to exist any indebtedness for
borrowed money secured by a mortgage, security interest, pledge, lien or other
encumbrance upon any shares of stock of any restricted subsidiary without
effectively providing that the senior debt securities shall be secured equally
and ratably with the indebtedness.

    The term "restricted subsidiary" is defined in the senior indenture as any
operating subsidiary of Sierra Pacific that accounts for [10%] or more of the
consolidated revenues and/or assets of Sierra Pacific.

    LIMITATIONS ON THE ISSUANCE OR DISPOSITION OF STOCK OF RESTRICTED
     SUBSIDIARIES.

    Sierra Pacific will not, nor will it permit any restricted subsidiary to,
issue, sell, assign, transfer or otherwise dispose of, directly or indirectly,
any "capital stock" of any restricted subsidiary, except for:

    - the purpose of qualifying directors;

    - sales or other dispositions to Sierra Pacific or one or more restricted
      subsidiaries;

    - the disposition of all or any part of the capital stock of any restricted
      subsidiary for consideration which is at least equal to the fair value of
      the capital stock as determined by Sierra Pacific's board of directors
      (acting in good faith); or

    - an issuance, sale, assignment, transfer or other disposition required to
      comply with an order of a court or regulatory authority of competent
      jurisdiction, other than an order issued at the request of Sierra Pacific
      or any restricted subsidiary.

    The term "capital stock" is defined in the senior indenture as any and all
shares, interests, rights to purchase, warrants, options, participations or
other equivalents of or interests in corporate stock.

DEFEASANCE

    The indentures provide Sierra Pacific with the option to discharge itself
from (a) all obligations of the debt securities of a series (except for
administrative obligations) or (b) compliance with the covenants of the
indentures. To exercise either option Sierra Pacific must irrevocably deposit in
trust with the indenture trustee money or obligations of, or guaranteed by, the
United States sufficient to pay all of the principal of (including any mandatory
redemption payments), premium, additional amounts and interest on the debt
securities on the dates the payments are due. To exercise either option, Sierra
Pacific is required to deliver to the indenture trustee an opinion of tax
counsel that the deposit and related defeasance would not cause the holders of
the debt securities to recognize income, gain or loss for Federal income tax
purposes. To exercise the option described in clause (a) above, the tax opinion
must be based either on a ruling of the Internal Revenue Service or a change in
the applicable Federal income tax law.

FORM, REGISTRATION, TRANSFER AND EXCHANGE

    Each series of debt securities will be issued in fully registered form
without coupons or in bearer form with or without coupon. Unless the applicable
prospectus supplement provides otherwise, registered senior debt securities will
be issued in denominations of $1,000 or integral multiples thereof and senior
debt securities issued in bearer form will be issued in the denomination of
$5,000. Unless the applicable prospectus supplement provides otherwise,
subordinated debt securities will be issuable only in registered form without
coupons in denominations of $25 and any integral multiple thereof. Each
indenture provides that debt securities may be issued in global form. If any
series of debt securities is issuable in global form, the applicable prospectus
supplement will describe the circumstances, if any, under which beneficial
owners of interests in any of those global debt securities may exchange their
interests for debt securities of that series and of like tenor and principal
amount in any authorized form and denomination.

    Holders may present debt securities for exchange, and registered debt
securities for transfer, in the manner, at the places and subject to the
restrictions set forth in the applicable indenture, the debt securities and the
applicable prospectus supplement. Holders may transfer senior debt securities in
bearer form and the coupons, if any, appertaining to the senior debt securities
will be transferrable by delivery. There will be no service charge for any
registration of transfer of registered debt securities or exchange of debt
securities, but Sierra Pacific may require payment of a sum sufficient to cover
any tax or other governmental charges that may be imposed in connection with any
registration of transfer or exchange. Bearer securities will not be issued in
exchange for registered securities.

    In the event of any redemption of debt securities of any series, Sierra
Pacific will not be required to

    - register the transfer of or exchange debt securities of that series during
      a period of 15 days next preceding the selection of securities of the
      series to be redeemed;

    - register the transfer of or exchange any registered debt security called
      for redemption, except the unredeemed portion of any registered debt
      security being redeemed in part; or

    - exchange any bearer security called for redemption except, to the extent
      provided with respect to any series of debt securities and referred to in
      the applicable prospectus supplement, to exchange the bearer security for
      a registered debt security of like tenor and principal amount that is
      immediately surrendered for redemption.

GLOBAL SECURITIES

    The debt securities of each series may be issued in whole or in part in
global form. A debt security in global form will be deposited with, or on behalf
of, a depositary, which will be named in an applicable prospectus supplement. A
global security may be issued in either registered or bearer form and in either
temporary or definitive form. A global debt security may not be transferred,
except as a whole, among the depositary for such debt security and/or its
nominees and/or successors. If any debt securities of a series are issuable as
global securities, the applicable prospectus supplement will describe any
circumstances when beneficial owners of interests in any global security may
exchange those interests for definitive debt securities of like tenor and
principal amount in any authorized form and denomination and the manner of
payment of principal and interest on any global debt security.

PAYMENT AND PAYING AGENTS

    Unless otherwise indicated in the applicable prospectus supplement, payment
of the interest on any debt securities (other than bearer securities) on any
interest payment date will be made to the person in whose name the debt
securities are registered.

                                       11
<PAGE>
    Unless otherwise indicated in the applicable prospectus supplement,
principal of and any premium, additional amounts and interest on the debt
securities (other than bearer securities) of a particular series will be payable
at the office of the paying agents designated by Sierra Pacific. Unless
otherwise indicated in the prospectus supplement, the principal corporate trust
office of the applicable trustee in The City of New York will be designated as
sole paying agent for payments with respect to debt securities of each series.

    All moneys paid by Sierra Pacific to a paying agent or the trustee for the
payment of the principal, premium additional amounts or interest on a debt
security which remains unclaimed at the end of one year will be repaid to Sierra
Pacific, and the holder of the debt security thereafter may look only to Sierra
Pacific for payment thereof.

GOVERNING LAW

    The indentures and debt securities will be governed by and construed under
the laws of [the State of             ].

             DESCRIPTION OF THE PREFERRED SECURITIES OF THE TRUSTS

GENERAL

    The preferred securities of each trust will be issued under the terms of its
declaration. Each declaration will be qualified as an indenture under the Trust
Indenture Act. The property trustee of each trust, The Bank of New York, will
act as trustee for the preferred securities under each declaration for purposes
of compliance with the provisions of the Trust Indenture Act. The following
summary of the material terms and provisions of the preferred securities of each
trust is not complete and is subject to, and qualified in its entirety by
reference to, the declarations, copies of which are filed as an exhibit to the
registration statement of which this prospectus is a part, the Delaware Business
Trust Act and the Trust Indenture Act.

    Each declaration authorizes the administrative trustees of each trust to
issue its Trust Securities, which represent undivided beneficial ownership
interests in the assets of the respective trusts. The proceeds from the sale of
Trust Securities will be used by a trust to purchase a series of subordinated
debt securities issued by Sierra Pacific. The subordinated debt securities
purchased by a trust will be held by the trust's property trustee for the
benefit of the holders of its Trust Securities.

    The declarations do not permit the trusts to:

    - acquire any assets other than subordinated debt securities issued by
      Sierra Pacific;

    - issue any securities other than Trust Securities; or

    - incur any indebtedness.

    The payment of distributions out of money held by the trusts, and payments
out of money held by the trusts upon redemption of preferred securities or
liquidation of the trusts, are guaranteed by Sierra Pacific to the extent
described under "Description of Preferred Securities Guarantee."

    Each preferred securities guarantee will be held by The Bank of New York,
the guarantee trustee, for the benefit of the holders of preferred securities of
each trust. A preferred securities guarantee does not cover payment of
distributions when a trust does not have sufficient available funds to pay such
distributions.

    The prospectus supplement relating to the preferred securities of a trust
will describe the specific terms of a trust's preferred securities, including:

    - the name of the preferred securities;

    - the dollar amount and number of securities issued;

                                       12
<PAGE>
    - any provision relating to deferral of distribution payments;

    - the annual distribution rate(s), the payment date(s) and the record dates
      used to determine the holders who are to receive distributions;

    - the optional redemption provisions, if any, including the prices, time
      periods and other terms and conditions for which the preferred securities
      shall be purchased or redeemed, in whole or in part;

    - the terms and conditions, if any, upon which the applicable series of
      subordinated debt securities may be distributed to holders of the
      preferred securities;

    - the voting rights, if any, of holders of the preferred securities;

    - any securities exchange on which the preferred securities will be listed;

    - whether the preferred securities are to be issued in book-entry form and
      represented by one or more global certificates; and

    - any other relevant rights, preferences, privileges, limitations or
      restrictions of such preferred securities.

    Each prospectus supplement will describe United States Federal income tax
considerations applicable to the purchase, holding and disposition of the
preferred securities covered by that prospectus supplement.

DISTRIBUTIONS

    Distributions on the preferred securities will be cumulative, will
accumulate from the date of original issuance unless otherwise specified in the
applicable prospectus supplement and will be payable on the dates specified in
the applicable prospectus supplement. In the event that any date on which
distributions are payable on the preferred securities is not a Business Day (as
defined below), payment of the distribution payable on that date will be made on
the next succeeding day that is a Business Day. If the next succeeding day that
is a Business Day is in the next succeeding calendar year, payment of a
distribution shall be made on the immediately preceding Business Day. A
"Business Day" means any day other than a Saturday or a Sunday, or a day on
which banking institutions in The City of New York are authorized or required by
law or executive order to remain closed or a day on which the corporate trust
office of the property trustee or the subordinated indenture trustee is closed
for business.

    Distributions on the preferred securities of a trust will be made to the
extent that the trust has funds available for the payment of the distributions
in the property account. Amounts available to a trust for distribution to the
holders of its preferred securities will be limited to payments received by the
trust from Sierra Pacific with respect to subordinated debt securities from
Sierra Pacific on Sierra Pacific's guarantee on the preferred securities as
described in this prospectus.

    If provided in the applicable prospectus supplement, Sierra Pacific has the
right under the subordinated indenture to defer the payment of interest at any
time or from time to time on any series of subordinated debt securities issued
to a trust for a period which will be specified in the prospectus supplement
(each an "extension period"). No extension period may extend beyond the stated
maturity of the subordinated debt securities. As a consequence of any extension,
distributions on the preferred securities would be deferred (but would continue
to accumulate additional distributions thereon at the rate per annum shown in
the prospectus supplement) during any extension period. During an extension
period Sierra Pacific may not, and may not permit any of its subsidiaries to:

    - declare or pay any dividends or distributions on, or redeem, purchase,
      acquire or make a liquidation payment with respect to, any of its capital
      stock other than cash dividends paid by Sierra Pacific Power Company and
      Nevada Power Company to Sierra Pacific,

                                       13
<PAGE>
    - make any payment of principal, interest or premium, if any, on or repay,
      repurchase or redeem any debt securities that rank PARI PASSU with or
      junior in interest to the subordinated debt securities, or

    - make any guarantee payments with respect to any guarantee by Sierra
      Pacific of debt securities of any subsidiary of Sierra Pacific if the
      guarantee ranks PARI PASSU or junior in interest to the subordinated debt
      securities.

MANDATORY REDEMPTION

    Upon the repayment or redemption, in whole or in part, of any subordinated
debt securities issued to a trust, whether at maturity or upon earlier
redemption as provided in the subordinated indenture, the proceeds from the
repayment or redemption shall be applied by the property trustee to redeem a
like amount of the Trust Securities, upon not less than 30 nor more than 60 days
notice, at a redemption price (the "redemption price") equal to the aggregate
liquidation amount of the Trust Securities plus accumulated but unpaid
distributions to the date of redemption and the related amount of the premium,
if any, paid by Sierra Pacific upon the concurrent redemption of the
subordinated debt securities. See "Description of Debt Securities--Redemption."

    If less than all of any series of subordinated debt securities are to be
repaid or redeemed on a redemption date, then the proceeds from that repayment
or redemption shall be allocated to the redemption PRO RATA among the related
preferred securities and the common securities. The amount of premium, if any,
paid by Sierra Pacific upon the redemption of all or any part of any series of
subordinated debt securities to be repaid or redeemed on a redemption date shall
be allocated to the redemption PRO RATA among the related preferred securities
and the common securities.

    Sierra Pacific will have the right to redeem any series of subordinated debt
securities:

    - in whole at any time or in part from time to time, subject to the
      conditions described under "Description of Debt Securities--Redemption,"

    - at any time, in whole (but not in part), upon the occurrence of a Trust
      Tax Event or an Trust Investment Company Event (each as defined below), or

    - as may be otherwise specified in the applicable prospectus supplement.

TRUST SPECIAL EVENT REDEMPTION OR DISTRIBUTION

    If, at any time, a "Trust Tax Event" or a "Trust Investment Company Event"
(each as defined below, and each, a "Trust Special Event") shall occur and be
continuing, the administrative trustees of each trust shall, within 90 days
following the occurrence of the Trust Special Event elect to either:

    - dissolve the trust upon not less than 30 nor more than 60 days notice with
      the result that, after satisfaction of creditors of the trust, if any,
      subordinated debt securities held by the trust would be distributed on a
      pro rata basis to the holders of the Trust Securities in liquidation of
      the holders' interests in the trust; PROVIDED, HOWEVER, that if at the
      time there is available to the trust the opportunity to eliminate, within
      the 90-day period, the Trust Special Event by taking some ministerial
      action, such as filing a form or making an election, or pursuing some
      other similar reasonable measure which in the sole judgment of Sierra
      Pacific has or will cause no adverse effect on the trust, Sierra Pacific
      or the holders of the Trust Securities and will involve no material cost,
      the trust will pursue that measure in lieu of dissolution; or

    - cause the preferred securities of the trust to remain outstanding,
      provided that, Sierra Pacific shall pay any and all expenses incurred by
      or payable by the trust attributable to the Trust Special Event.

    Furthermore, if in the case of the occurrence of a Trust Tax Event, the
administrative trustees have received an opinion of nationally recognized
independent tax counsel experienced in these matters that

                                       14
<PAGE>
there is more than an insubstantial risk that interest payable with respect to
the subordinated debt securities issued by Sierra Pacific is not, or will not
be, deductible by Sierra Pacific for United States Federal income tax purposes
even if the subordinated debt securities were distributed to the holders of
Trust Securities as described above, then Sierra Pacific shall have the right,
within 90 days following the occurrence of the Trust Tax Event, to redeem the
subordinated debt securities in whole, but not in part, for cash upon not less
than 30 nor more than 60 days notice and promptly following any redemption, the
Trust Securities will be redeemed by the trust at the redemption price.

    "Trust Tax Event" means that Sierra Pacific shall have requested and
received and shall have delivered to the administrative trustees an opinion of
nationally recognized independent tax counsel experienced in these matters to
the effect that there has been:

    - an amendment to, change in or announced proposed change in the laws, or
      any regulations under those laws of the United States or any political
      subdivision or taxing authority of that jurisdiction,

    - a judicial decision interpreting, applying, or clarifying these laws or
      regulations,

    - an administrative pronouncement or action that represents an official
      position, including a clarification of an official position, of the
      governmental authority or regulatory body making the administrative
      pronouncement or taking any action, or

    - a threatened challenge asserted in connection with an audit of Sierra
      Pacific or the trusts, or a threatened challenge asserted in writing
      against any other taxpayer that has raised capital through the issuance of
      securities that are substantially similar to the subordinated debt
      securities or the preferred securities, which amendment or change is
      adopted or which proposed change, decision or pronouncement is announced
      or which action, clarification or challenge occurs on or after the date of
      this prospectus (collectively a "Tax Action"), which tax action relates to
      any of the items described in (1) through (3) below, and that following
      the occurrence of any Tax Action there is more than an insubstantial risk
      that:

    (1) the trusts are, or will be, subject to United States Federal income tax
       with respect to income accrued or received on the subordinated debt
       securities,

    (2) the trusts are, or will be, subject to more than a minimal amount of
       other taxes, duties or other governmental charges or

    (3) interest payable by Sierra Pacific with respect to the subordinated debt
       securities issued to the trusts is not, or will not be, deductible by
       Sierra Pacific for United States Federal income tax purposes.

    "Trust Investment Company Event" means that Sierra Pacific shall have
requested and received and shall have delivered to the administrative trustees
an opinion of nationally recognized independent legal counsel experienced in
these matters to the effect that as a result of the occurrence on or after the
date of this prospectus of a change in law or regulation or a change in
interpretation or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority (a "Change in Investment
Company Act Law"), the trusts are or will be considered investment companies
which are required to be registered under the Investment Company Act.

    If subordinated debt securities are distributed to the holders of preferred
securities, Sierra Pacific will use its best efforts to cause the subordinated
debt securities to be listed on the NYSE or on any other national securities
exchange or similar organization as the preferred securities are then listed or
quoted.

    On the date fixed for any distribution of subordinated debt securities, upon
dissolution of a trust,

    - the Trust Securities of the trust will no longer be deemed to be
      outstanding, and

                                       15
<PAGE>
    - certificates representing the Trust Securities will be deemed to represent
      the subordinated debt securities having a liquidation preference equal to
      the stated liquidation amount of the Trust Securities until the
      certificates are presented to Sierra Pacific or its agent for transfer or
      reissuance.

    If a dissolution and liquidation of the trusts were to occur, subordinated
debt securities which an investor may subsequently receive on dissolution and
liquidation of the trusts may trade at a discount to the price of the preferred
securities exchanged.

REDEMPTION PROCEDURES

    The trusts may not redeem fewer than all of their outstanding preferred
securities unless all accumulated and unpaid distributions have been paid on all
of their preferred securities for all quarterly distribution periods terminating
on or before the date of redemption.

    If a trust gives a notice of redemption of its preferred securities, which
notice will be irrevocable, and if Sierra Pacific has paid to the property
trustee a sufficient amount of cash in connection with the related redemption of
the subordinated debt securities held by the trust, then, by 12:00 noon, New
York City time, on the redemption date, the trust will irrevocably deposit with
DTC funds sufficient to pay the amount payable on redemption of all book entry
certificates and will give DTC irrevocable instructions and authority to pay the
redemption amount to holders of the preferred securities. See "Book-Entry Only
Issuance--The Depository Trust Company." If notice of redemption shall have been
given and funds are deposited as required, then upon the date of deposit, all
rights of holders of any preferred securities called for redemption in this
manner will cease, except the right of the holders of those preferred securities
to receive the redemption price, without interest. In the event that any date
fixed for redemption of the preferred securities is not a Business Day, then
payment of the amount payable on that date will be made on the next succeeding
day which is a Business Day, without any interest or other payment in respect of
the amount payable subject to delay, except that, if the next succeeding day
that is a Business Day falls in the next calendar year, the payment will be made
on the immediately preceding Business Day. In the event that payment of the
redemption price in respect of the preferred securities is improperly withheld
or refused and not paid either by the trust or by Sierra Pacific under the
applicable trust guarantee described under "Description of the Preferred
Securities Guarantee," distributions on the preferred securities will continue
to accumulate from the original redemption date to the date of payment.

    In the event that fewer than all of the outstanding preferred securities are
to be redeemed, the preferred securities will be redeemed in accordance with the
procedures of DTC. See "--Book-Entry Only Issuance--The Depository Trust
Company". In the event that the Preferred Securities do not remain in book-entry
only form and fewer than all of the outstanding preferred securities are to be
redeemed, the preferred securities shall be redeemed on a pro rata basis or
pursuant to the rules of any securities exchange on which the preferred
securities are listed.

    Subject to the foregoing and applicable law, including United States Federal
securities laws, Sierra Pacific or its subsidiaries may at any time and from
time to time purchase outstanding preferred securities by tender, in the open
market or by private agreement.

LIQUIDATION DISTRIBUTION UPON DISSOLUTION

    If there is a voluntary or involuntary liquidation, dissolution, winding-up
or termination of a trust, the holders of the preferred securities of that trust
will be entitled to receive out of the assets of the trust, after satisfaction
of liabilities to creditors, distributions in cash or other immediately
available funds in an amount equal to the aggregate of the stated liquidation
amount per preferred security plus accumulated and unpaid distributions to the
date of payment, unless, in connection with the trust's liquidation,
subordinated debt securities have been distributed on a pro rata basis to the
holders of its Trust Securities.

                                       16
<PAGE>
    If, upon any trust's liquidation, the liquidation distribution can be paid
only in part because the trust has insufficient assets available to pay in full
the aggregate liquidation distribution, then the amounts payable directly by the
trust on its preferred securities shall be paid on a pro rata basis. The holders
of the common securities of the trust will be entitled to receive distributions
upon liquidation pro rata with the holders of the preferred securities, except
in the limited circumstances described below under "--Subordination of the
Common Securities".

    Each trust shall dissolve:

    - upon the bankruptcy of Sierra Pacific,

    - upon the filing of a certificate of dissolution or the equivalent with
      respect to Sierra Pacific, dissolution of the trust after having obtained
      the consent of at least a majority in liquidation amount of the trust's
      securities, voting together as a single class, or the revocation of Sierra
      Pacific's certificate of incorporation, and the expiration of 90 days
      after the date of revocation without reinstatement,

    - upon the distribution of all of the subordinated debt securities upon the
      occurrence of a Trust Special Event,

    - upon the entry of a decree of a judicial dissolution of Sierra Pacific or
      the applicable trust, or

    - upon the redemption of all the applicable Trust Securities.

SUBORDINATION OF THE COMMON SECURITIES

    Payment of amounts upon liquidation of a trust's Trust Securities shall be
made pro rata based on the liquidation amount of the Trust Securities; provided,
however, that upon:

    - the occurrence of an event of default by Sierra Pacific in respect of
      subordinated debt securities, or

    - default by Sierra Pacific on any of its obligations under any guarantee
      described in this prospectus,

the holders of the affected trust's preferred securities will have a preference
over the holders of the trust's common securities with respect to payments upon
liquidation of the trust.

    In the case of any event of default by Sierra Pacific in respect of
subordinated debt securities, the holder of the common securities will be deemed
to have waived any right in connection with the event of default until the event
of default with respect to the preferred securities have been cured, waived or
otherwise eliminated. Until all events of default with respect to the preferred
securities have been cured in this manner, waived or otherwise eliminated, the
property trustee of the trust shall act solely on behalf of the holders of the
trust's preferred securities and not on behalf of the holder of the common
securities, and only the holders of the preferred securities will have the right
to direct the property trustee to act on their behalf.

AMENDMENT OF DECLARATIONS

    Each declaration may be modified and amended if approved and executed by the
administrative trustees of a trust, except that:

    - no amendment shall be made, and any purported amendment shall be void and
      ineffective, to the extent the result thereof would be to:

     (1) cause a trust to fail to be classified for the purposes of United
         States Federal income taxation as a grantor trust;

                                       17
<PAGE>
     (2) affect the powers or the rights of the property trustee or the Delaware
         trustee of a trust without their written consent; or

     (3) cause a trust to be deemed an "investment company" which is required to
         be registered under the Investment Company Act;

    - at the time after a trust has issued any securities which remain
      outstanding, any amendment which would materially adversely affect the
      rights, privileges or preferences of any holder of the securities may be
      effected only with the additional requirements as may be set forth in the
      terms of the securities of a trust;

    - provisions in the declarations regarding the transferability of the common
      securities of a trust and regarding the amendment of the declarations
      cannot be amended without the consent of all of the holders of the
      securities of a trust;

    - provisions in the declarations regarding Sierra Pacific cannot be amended
      without Sierra Pacific's consent; and

    - Sierra Pacific's rights to increase or decrease the number of, and appoint
      and remove, trustees of a trust shall not be amended without Sierra
      Pacific's consent.

    Notwithstanding the foregoing, each declaration may be amended from time to
time by the holders of a majority in liquidation amount of the common securities
of the trust and its property trustee, without the consent of the holders of the
preferred securities, to:

    - cure any ambiguity;

    - correct or supplement any provision in a declaration that may be defective
      or inconsistent with any other provision in that declaration or to make
      any other provisions with respect to matters or questions arising under a
      declaration, which shall not be inconsistent with the other provisions of
      the declaration;

    - add to the covenants, restrictions or obligations of Sierra Pacific;

    - ensure the applicable trust's classification as a grantor trust for United
      States Federal income tax purposes and conform to any change in the
      Investment Company Act, the Trust Indenture Act or the rules or
      regulations under either law; and

    - to modify, eliminate or add to any provisions of a declaration to the
      extent necessary to ensure that the applicable trust will not be required
      to register as an "investment company" under the Investment Company Act.

VOTING RIGHTS

    Except as provided below and under "Description of Preferred Securities
Guarantee-- Amendments and Assignment" and as otherwise required by law and the
declarations, the holders of the preferred securities of the trusts will have no
voting rights.

    The holders of a majority in aggregate liquidation amount of the preferred
securities of each trust have the right to:

    - direct the time, method and place of conducting any proceeding for any
      remedy available to the property trustee of the trust; or

    - direct the exercise of the power conferred upon the property trustee under
      the trust's declaration, including the right to direct the property
      trustee, as the holder of a series of subordinated debt securities, to

                                       18
<PAGE>
     (a) exercise the remedies available under the subordinated indenture with
         respect to the subordinated debt securities;

     (b) waive any event of default under the subordinated indenture that is
         waivable;

     (c) cancel an acceleration of the principal of the subordinated debt
securities; or

     (d) consent to any amendment, modification or termination of the
subordinated indenture or the subordinated debt securities where consent shall
be required.

However, if the subordinated indenture requires the consent of the holders of
more than a majority in aggregate principal amount of a series of subordinated
debt securities with respect to any waiver or consent, then the property trustee
for the series must get approval of the holders of the super-majority in
liquidation amount of the series of preferred securities.

    In addition, before taking any of the foregoing actions, the property
trustee must obtain an opinion of counsel stating that, as a result of the
action, the trust will continue to be classified as a grantor trust for United
States Federal income tax purposes.

    The property trustee of a trust will notify all preferred securities holders
of any notice received from the subordinated indenture trustee with respect to
the subordinated debt securities held by the trust.

    Any required approval or direction of holders of preferred securities of a
trust may be given at a separate meeting of holders of the preferred securities
of the trust convened for that purpose, at a meeting of all of the holders of
Trust Securities or through written consent.

    If a vote of preferred securities holders is taken or a consent is obtained,
any preferred securities that are owned by Sierra Pacific or any of its
affiliates will, for purposes of the vote or consent, be treated as if they were
not outstanding. This means:

    - Sierra Pacific and any of its affiliates will not be able to vote on or
      consent to matters requiring the vote or consent of holders of preferred
      securities; and

    - any preferred securities owned by Sierra Pacific or any of its affiliates
      will not be counted in determining whether the required percentage of
      votes or consents has been obtained.

DECLARATION EVENTS OF DEFAULT

    Any one of the following events constitutes an "event of default" under the
declarations with respect to the preferred securities issued thereunder:

    - the occurrence of an event of default under the subordinated indenture
      (see "Description of Debt Securities--Events of Default");

    - a default by the property trustee in the payment of any distribution when
      it becomes due and payable, and continuation of the default for a period
      of 30 days;

    - a default by the property trustee in the payment of the redemption price
      of any Trust Security when it becomes due and payable;

    - default in the performance or breach, in any material respect, of any
      covenant or warranty of the administrative trustees, and continuation of
      the default or breach for a period of 60 days after appropriate written
      notice under the declaration; or

    - the occurrence of events of bankruptcy or insolvency with respect to the
      property trustee and the failure by Sierra Pacific to appoint a successor
      property trustee within 60 days thereof.

                                       19
<PAGE>
    Sierra Pacific and the administrative trustees of each trust must file
annually with the property trustee of each trust a certificate stating whether
or not they are in compliance with all the applicable conditions and covenants
under the applicable declaration.

    Upon the occurrence of an event of default under a declaration, the property
trustee, as the sole holder of the subordinated debt securities held by the
applicable trust, will have the right under the subordinated indenture to
declare the principal of, premium, if any, and interest on the subordinated debt
securities to be immediately due and payable.

    If the property trustee fails to enforce its rights under the terms of the
applicable subordinated debt securities after a holder of preferred securities
has made a written request, the holder may, to the extent permitted by
applicable law, sue Sierra Pacific, or seek other remedies, to enforce the
property trustee's rights under the subordinated indenture without first
instituting a legal proceeding against the property trustee, the trust or any
other person or entity.

    If Sierra Pacific fails to pay principal, premium, if any, or interest on a
series of subordinated debt securities when payable, then a holder of the
related preferred securities issued by the affected trust may directly sue
Sierra Pacific or seek other remedies, to collect its pro rata share of payments
owed.

MERGER, CONSOLIDATION OR AMALGAMATION OF THE TRUSTS

    Neither trust may consolidate, amalgamate, convert into, merge with or into,
or be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, any corporation or other entity, except as
described below or as described in "Liquidation Distribution Upon Dissolution".
Each trust may, with the consent of a majority of the administrative trustees of
the trust and without the consent of the holders of the Trust Securities, the
property trustee or the Delaware trustee consolidate, amalgamate, convert into,
merge with or into, or be replaced by a new trust organized under the laws of
any State of the United States; provided, that:

    - if the trust is not the surviving entity, the successor entity either:

      - substitutes for the preferred securities other securities having
        substantially the same terms as the preferred securities (the "successor
        securities"), so long as the successor securities rank the same as the
        trust securities with respect to distributions, assets and payments; or

      - expressly assumes all of the obligations of the trust under the Trust
        Securities, and

    - Sierra Pacific expressly acknowledges a trustee of the successor entity
      possessing the same powers and duties as the property trustee;

    - the preferred securities or any successor securities are listed, or any
      successor securities will be listed upon notification of issuance, on any
      national securities exchange or with another organization on which the
      preferred securities are then listed or quoted;

    - any merger, consolidation, amalgamation, conversion or replacement does
      not cause the preferred securities, including any successor securities, to
      be downgraded by any nationally recognized statistical rating
      organization;

    - any merger, consolidation, amalgamation, conversion or replacement does
      not adversely affect the rights, preferences and privileges of the holders
      of the preferred securities, including any successor securities, in any
      material respect;

    - the successor entity has a purpose substantially identical to that of the
      trust;

    - Sierra Pacific guarantees the obligations of the successor entity under
      the successor securities to the same extent as provided by the trust
      guarantee; and

                                       20
<PAGE>
    - before any merger, consolidation, amalgamations, conversion or
      replacement, Sierra Pacific has received an opinion of a nationally
      recognized independent counsel to the trust experienced in these matters
      to the effect that:

      - any merger, consolidation, amalgamations, conversion or replacement will
        not adversely affect the rights, preferences and privileges of the
        holders of the preferred securities, including any successor securities,
        in any material respect, other than with respect to any dilution of the
        holders' interest in the new entity;

      - following any merger, consolidation, amalgamations, conversion or
        replacement, neither the trust nor the successor entity will be required
        to register as an investment company under the Investment Company Act;
        and

      - following any merger, consolidation, amalgamations, conversion or
        replacement, the trust, or any successor trust, will not be classified
        as an association or a publicly traded partnership taxable as a
        corporation for United States Federal income tax purposes.

Notwithstanding the foregoing, each trust shall not, except with the consent of
holders of 100% in liquidation amount of the preferred securities of the trust,
consolidate, amalgamate, merge with or into, or be replaced by any other entity
or permit any other entity to consolidate, amalgamate, conversion, merge with or
into, or replace it, if any consolidation, amalgamation, conversion, merger or
replacement would cause the trust or the successor entity to be classified as an
association or a publicly traded partnership taxable as a corporation for United
States Federal income tax purposes.

REMOVAL AND REPLACEMENT OF TRUSTEES

    Only the holder of a trust's common securities has the right to remove or
replace the trustees of the applicable trust. The resignation or removal of any
trustee and the appointment of a successor trustee shall be effective only on
the acceptance of appointment by the successor trustee under the provisions of
the applicable declaration.

REGISTRAR, TRANSFER AGENT, AND PAYING AGENT

    Unless otherwise specified in the applicable prospectus supplement, the
property trustee of a trust will act as registrar, transfer agent and paying
agent for the preferred securities of the trust.

    Registration of transfers of the preferred securities of a trust will be
effected without charge by or on behalf of the trust, but upon payment and with
the giving of any indemnity as the trust or Sierra Pacific may require, in
respect of any tax or other government charges which may be imposed in relation
to it.

    The trusts will not be required to register or cause to be registered the
transfer of their preferred securities after the preferred securities have been
called for redemption.

BOOK-ENTRY ONLY ISSUANCE--THE DEPOSITORY TRUST COMPANY

    DESCRIPTION OF THE GLOBAL CERTIFICATES.

    DTC will act as securities depository for the preferred securities and, to
the extent distributed to the holders of the preferred securities, the
subordinated debt securities held by a trust. The preferred securities will be
issued only as fully-registered securities registered in the name of Cede & Co.
(DTC's nominee). One or more fully-registered global certificates, representing
the total aggregate number of preferred securities, will be issued and will be
deposited with DTC.

                                       21
<PAGE>
    DTC PROCEDURES.

    DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934, as amended. DTC holds securities that its participants deposit with
DTC. DTC also facilitates the settlement among participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in participants' accounts, thereby
eliminating the need for physical movement of securities certificates.
Participants in DTC include securities brokers and dealers, banks, trust
companies, clearing corporations and other organizations. DTC is owned by a
number of its participants and by the New York Stock Exchange, the American
Stock Exchange and the National Association of Securities Dealers, Inc. Access
to the DTC system is also available to others, including securities brokers and
dealers, banks and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly. The rules
applicable to DTC and its participants are on file with the SEC.

    Purchases of preferred securities within the DTC system must be made by or
through participants, which will receive a credit for the preferred securities
on DTC's records. The ownership interest of each beneficial owner of preferred
securities is in turn to be recorded on the participants' and indirect
participants' records. Beneficial owners will not receive written confirmation
from DTC of their purchases, but beneficial owners are expected to receive
written confirmations providing details of the transactions, as well as periodic
statements of their holdings, from the participants or indirect participants
through which the beneficial owners purchased preferred securities. Transfers of
ownership interests in preferred securities are to be accomplished by entries
made on the books of participants and indirect participants acting on behalf of
beneficial owners. Beneficial owners will not receive certificates representing
their ownership interests in the preferred securities, except in the event that
use of the book-entry system for the preferred securities is discontinued.

    DTC has no knowledge of the actual beneficial owners of preferred
securities; DTC's records reflect only the identity of the participants to whose
accounts the preferred securities are credited, which may or may not be the
beneficial owners. The participants and indirect participants will remain
responsible for keeping account of their holdings on behalf of their customers.

    So long as DTC, or its nominee, is the registered owner or holder of a
global certificate, DTC or the nominee, as the case may be, will be considered
the sole owner or holder of the preferred securities being represented for all
purposes under the declarations. No beneficial owner of an interest in a global
certificate will be able to transfer that interest except in accordance with
DTC's applicable procedures, in addition to those provided for under the
declarations.

    DTC has advised Sierra Pacific that it will take any action permitted to be
taken by a holder of preferred securities, including the presentation of
preferred securities for exchange as described below, only at the direction of
one or more participants to whose account the DTC interests in the global
certificates are credited and only in respect of the portion of the aggregate
liquidation amount of the preferred securities as to which the participant or
participants has or have given the direction. Also, if there is an event of
default under the declarations, DTC will exchange the global certificates for
certificated securities, which it will distribute to its participants in
accordance with its customary procedures.

    Conveyance of notices and other communications by DTC to participants, by
participants to indirect participants, and by participants and indirect
participants to beneficial owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements as may be in effect from
time to time.

                                       22
<PAGE>
    Redemption notices in respect of preferred securities held in book-entry
form will be sent to Cede & Co. If less than all of the preferred securities are
being redeemed, DTC will determine the amount of the interest of each
participant to be redeemed in accordance with its procedures.

    Although voting with respect to preferred securities is limited, in those
cases where a vote is required, neither DTC nor Cede & Co. will itself consent
or vote with respect to the preferred securities. Under its usual procedures,
DTC would mail an omnibus proxy to the issuing trust as soon as possible after
the record date. The omnibus proxy assigns Cede & Co.'s consenting or voting
rights to those participants to whose accounts the preferred securities are
allocated on the record date identified in a listing attached to the omnibus
proxy.

    Distributions on the preferred securities held in book-entry form will be
made to DTC in immediately available funds. DTC's practice is to credit
participants' accounts on the relevant payment date in accordance with their
respective holdings shown on DTC's records unless DTC has reason to believe that
it will not receive payments on the payment date. Payments by participants and
indirect participants to beneficial owners will be governed by standing
instructions and customary practices and will be the responsibility of the
participants and indirect participants and not of DTC, the trusts or Sierra
Pacific, subject to any statutory or regulatory requirements as may be in effect
from time to time. Payment of any distributions to DTC is the responsibility of
the trusts, disbursement of those payments to participants is the responsibility
of DTC, and disbursement of those payments to the beneficial owners is the
responsibility of participants and indirect participants.

    Except as described in the applicable prospectus supplement, a beneficial
owner of an interest in a global certificate will not be entitled to receive
physical delivery of the preferred securities. Accordingly, each beneficial
owner must rely on the procedures of DTC to exercise any rights under the
preferred securities.

    Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the global certificates among participants of DTC, DTC
is under no obligation to perform or continue to perform the procedures, and the
procedures may be discontinued at any time. Neither Sierra Pacific nor the
trusts will have any responsibility for the performance by DTC or its
participants or indirect participants under the rules and procedures governing
DTC. DTC may discontinue providing its services as securities depository with
respect to the preferred securities at any time by giving notice to the issuing
trusts. If a successor securities depository is not obtained, preferred
securities certificates are required to be printed and delivered to the property
trustee. Additionally, each trust, with the consent of Sierra Pacific, may
decide to discontinue use of the system of book-entry transfers through DTC or
any successor depository. In that event, certificates for preferred securities
will be printed and delivered to the property trustee. In each of the above
circumstances, Sierra Pacific will appoint a paying agent with respect to the
preferred securities.

    The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of securities in definitive form. These laws may impair
the ability to transfer beneficial interests in the global preferred securities
as represented by a global certificate.

    The information in this section concerning DTC and DTC's system has been
obtained from sources that Sierra Pacific believes to be reliable, but Sierra
Pacific takes no responsibility for the accuracy of the information.

INFORMATION CONCERNING THE PROPERTY TRUSTEE

    The property trustee of each trust, before the occurrence of a default with
respect to a trust's securities, undertakes to perform only the duties as are
specifically set forth in the trust' declaration and, after default, shall
exercise the same degree of care as a prudent individual would exercise in the
conduct of his or her own affairs. Otherwise, the property trustee is under no
obligation to exercise any

                                       23
<PAGE>
of the powers vested in it by a trust's declaration at the request of any holder
of the trust's preferred securities, unless offered reasonable indemnity
satisfactory to the property trustee by the holder against the costs, expenses
and liabilities which might be incurred in connection with the exercise of any
powers.

GOVERNING LAW

    The declarations and the preferred securities issued by the trusts will be
governed by, and construed in accordance with, the internal laws of the State of
Delaware.

MISCELLANEOUS

    The administrative trustees of a trust are authorized and directed to
conduct the affairs of and to operate the trust in a way that the trust will not
be deemed to be an investment company required to be registered under the
Investment Company Act or characterized as other than a grantor trust for United
States Federal income tax purposes. In this connection, the administrative
trustees of a trust are authorized to take any action, not inconsistent with
applicable law, the trust's certificate of trust or its declaration that the
administrative trustees determine in their discretion to be necessary or
desirable for those purposes as long as the action does not adversely affect the
interests of the holders of the preferred securities.

    Holders of the preferred securities of the trust will have no preemptive or
similar rights.

                                       24
<PAGE>
               DESCRIPTION OF THE PREFERRED SECURITIES GUARANTEES

    Set forth below is a summary of information concerning the preferred
securities guarantees which will be executed and delivered by Sierra Pacific for
the benefit of the holders of the preferred securities of a trust. The summary
is not complete and is subject in all respects to the provisions of, and is
qualified in its entirety by reference to, the preferred securities guarantees,
which are filed as an exhibit to the registration statement of which this
prospectus is a part. Each preferred securities guarantee incorporates by
reference the terms of, and will be qualified as an indenture under, the Trust
Indenture Act. The Bank of New York will act as the trustee under each preferred
securities guarantee ("guarantee trustee") and will hold the preferred
securities guarantees for the respective benefit of the holders of the preferred
securities.

GENERAL

    Under each preferred securities guarantee, Sierra Pacific will irrevocably
agree, on a subordinated basis and to the extent set forth in each preferred
securities guarantee, to pay in full to the holders of the preferred securities
of the trust, except to the extent paid by the trusts, as and when due,
regardless of any defense, right of set off or counterclaim which a trust may
have or assert, the following payments (the "guarantee payments"), without
duplication:

    - any accumulated and unpaid distributions on the preferred securities of a
      trust to the extent the trust has funds available for distribution;

    - the redemption price with respect to any preferred securities called for
      redemption by the trust, to the extent the trust has funds available for
      payment; and

    - upon a voluntary or involuntary dissolution, winding-up or termination of
      the trust, other than in connection with the distribution of subordinated
      debt securities to the holders of the preferred securities or the
      redemption of all of the preferred securities, the lesser of:

      - the aggregate of the liquidation amount and all accumulated and unpaid
        distributions on the preferred securities, and

      - the amount of assets of the trust remaining available for distribution
        to holders of the preferred securities upon the liquidation of the
        trust.

Sierra Pacific's obligation to make a guarantee payment may be satisfied by
direct payment of the required amounts by Sierra Pacific to the holders of the
preferred securities or by causing the trust to pay these amounts to holders.

    Each preferred securities guarantee will be a guarantee on a subordinated
basis with respect to the preferred securities of a trust but will only apply to
any payment of distributions or the redemption price, or to payments upon the
dissolution, winding-up or termination of a trust, to the extent the trust shall
have funds available. If Sierra Pacific fails to make payments on the
subordinated debt securities held by a trust, the trust would lack available
funds for the payment of distributions or amounts payable on redemption of its
preferred securities, and in that event holders of the preferred securities
would not be able to rely upon the preferred securities guarantee for payment of
these amounts. Instead, holders of the preferred securities will have the
remedies described under "Description of the Preferred Securities--Declaration
Events of Default", including the right to direct the guarantee trustee to
enforce the restriction of payments by Sierra Pacific and its subsidiaries on
its capital stock. See "--Events of Default" below.

    The preferred securities guarantees, when taken together with Sierra
Pacific's obligations under the declarations of trust, the subordinated
indenture, subordinated debt securities, and the expense agreement (see below),
constitute a guarantee to the extent set forth in this prospectus by Sierra
Pacific of the distribution, redemption and liquidation payments payable to the
holders of the preferred

                                       25
<PAGE>
securities of the trusts. No single document executed by Sierra Pacific in
connection with the issuance of any series of preferred securities will provide
for its full, irrevocable and unconditional guarantee of the preferred
securities.

EVENTS OF DEFAULT

    It shall be an event of default under a preferred securities guarantees if
Sierra Pacific fails to perform any of its payment or other obligations set
forth in the preferred securities guarantee.

    The holders of a majority in liquidation amount of the preferred securities
of a trust have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the guarantee trustee or to direct the
exercise of any power conferred upon the guarantee trustee under the preferred
securities guarantee applicable to the trust. If the guarantee trustee fails to
enforce its rights under a preferred securities guarantee after a holder of the
preferred securities has made a written request, the holder may institute a
legal proceeding directly against Sierra Pacific to enforce the guarantee
trustee's rights under that preferred securities guarantee, without first
instituting a legal proceeding against the applicable trust, the guarantee
trustee or any other person or entity. If Sierra Pacific has failed to make a
guarantee payment under a preferred securities guarantee, a holder of the
preferred securities may directly institute a proceeding in the holder's own
name against Sierra Pacific for enforcement of the preferred securities
guarantee for payment.

STATUS OF THE PREFERRED SECURITIES GUARANTEES; SUBORDINATION

    The preferred securities guarantees will constitute an unsecured obligation
of Sierra Pacific and will rank subordinate and junior in right of payment to
all senior indebtedness of Sierra Pacific. Sierra Pacific is a non-operating
holding company and substantially all of its operating assets are owned by its
subsidiaries. Sierra Pacific relies primarily on dividends from its subsidiaries
to meet its obligations for payment of principal and interest on its outstanding
debt and corporate expenses. Accordingly, the guarantees will be effectively
subordinated to all existing and future liabilities of Sierra Pacific's
subsidiaries. Except as otherwise provided in the applicable prospectus
supplement, there is no limit on the incurrence or issuance of other secured or
unsecured debt by Sierra Pacific or its subsidiaries. Holders of guarantees
should look only to the assets of Sierra Pacific for payments of principal,
interest and premium, if any.

    The preferred securities guarantees will rank PARI PASSU with all other
guarantees issued by Sierra Pacific.

AMENDMENTS AND ASSIGNMENT

    Except with respect to any changes that do not materially adversely affect
the rights of holders of preferred securities, in which case no vote will be
required, a preferred securities guarantee may be amended only with the prior
approval of the holders of at least a majority in liquidation amount of all the
outstanding preferred securities of the affected trust. The manner of obtaining
any approval of holders of the preferred securities will be as set forth under
"Description of the Preferred Securities of the Trusts--Voting Rights." All
guarantees and agreements contained in a preferred securities guarantee shall
bind the successors, assigns, receivers, trustees and representatives of Sierra
Pacific and shall inure to the benefit of the holders of the preferred
securities of the applicable trust then outstanding. Except in connection with
the permitted merger or consolidation of Sierra Pacific with or into another
entity or permitted sale, transfer or lease of Sierra Pacific's assets to
another entity in which the surviving corporation, if other than Sierra Pacific,
assumes Sierra Pacific's obligations under the preferred securities guarantees,
Sierra Pacific may not assign its rights or delegate its obligations under the
preferred securities guarantees without the prior approval of the holders of at
least a majority of the aggregate stated liquidation amount of the preferred
securities then outstanding.

                                       26
<PAGE>
TERMINATION OF THE PREFERRED SECURITIES GUARANTEES

    A preferred securities guarantee will terminate as to each holder of the
preferred securities of the applicable trust upon:

    - full payment of the redemption price of all the preferred securities,

    - distribution of the subordinated debt securities held by the trust to the
      holders of the preferred securities, or

    - full payment of the amounts payable under the declaration upon liquidation
      of the trust.

INFORMATION CONCERNING THE GUARANTEE TRUSTEE

    The guarantee trustee of each trust, before the occurrence of a default with
respect to a preferred securities guarantee, undertakes to perform only those
duties as are specifically set forth in a preferred securities guarantee and,
after default with respect to the preferred securities guarantee, shall exercise
the same degree of care as a prudent man would exercise in the conduct of his
own affairs. The guarantee trustee is under no obligation to exercise any of the
powers vested in it by a preferred securities guarantee at the request of any
holder of preferred securities unless it is offered reasonable indemnity against
the costs, expenses and liabilities that might be incurred in connection with
the exercise of those powers.

GOVERNING LAW

    The preferred securities guarantees will be governed by, and construed
under, the internal laws of the State of             .

THE EXPENSE AGREEMENT

    Under an expense agreement entered into by Sierra Pacific under each trust
agreement, Sierra Pacific will irrevocably and unconditionally guarantee to each
person or entity to whom a trust becomes indebted or liable, the full payment of
any costs, expenses or liabilities of the trust, other than obligations of the
trust to pay to the holders of the trust's preferred securities the amounts due
pursuant to the terms of the preferred securities.

    RELATIONSHIP AMONG PREFERRED SECURITIES, PREFERRED SECURITIES GUARANTEES
              AND SUBORDINATED DEBT SECURITIES HELD BY THE TRUSTS

    Payments of distributions and redemption and liquidation payments due on
each series of preferred securities (to the extent the applicable trust has
funds available for the payments) will be guaranteed by Sierra Pacific to the
extent described under "Description of Preferred Securities Guarantees." No
single document executed by Sierra Pacific in connection with the issuance of
any series of preferred securities will provide for its full, irrevocable and
unconditional guarantee of the preferred securities. It is only the combined
operation of Sierra Pacific's obligations under a preferred securities
guarantees, the declaration, subordinated indenture and subordinated debt
securities that has the effect of providing a full, irrevocable and
unconditional guarantee of a trust's obligations with respect to its preferred
securities.

    As long as Sierra Pacific makes payments of interest and other payments when
due on the subordinated debt securities held by a trust, the payments will be
sufficient to cover the payment of distributions and redemption and liquidation
payments due on the preferred securities issued by the trust, primarily because:

    - the aggregate principal amount of the subordinated debt securities will be
      equal to the sum of the aggregate liquidation amount of the preferred and
      common securities of the trust;

                                       27
<PAGE>
    - the interest rate and interest and other payment dates on the subordinated
      debt securities will match the distribution rate and any distribution and
      other payment dates for the preferred securities;

    - Sierra Pacific will pay for any and all costs, expenses and liabilities of
      the trust except for the trust's obligations under its preferred
      securities (and Sierra Pacific has agreed to guarantee the payments); and

    - the declaration provides that the trust will not engage in any activity
      that is not consistent with the limited purposes of the trust.

    If and to the extent that Sierra Pacific does not make payments on
subordinated debt securities held by a trust, the trust will not have funds
available to make payments of distributions or other amounts due on its
preferred securities. In those circumstances, holders of the preferred
securities will not be able to rely upon the preferred securities guarantee for
payment of these amounts. Instead, holders of the preferred securities may
directly sue Sierra Pacific or seek other remedies to collect their pro rata
share of payments owed. If a holder of preferred securities sues Sierra Pacific
to collect payment, then Sierra Pacific will assume the holders rights as a
holder of preferred securities under the applicable trust's declaration to the
extent Sierra Pacific makes a payment to the holder of preferred securities in
any legal action.

    A holder of any preferred security may sue Sierra Pacific, or seek other
remedies, to enforce its rights under a preferred securities guarantee without
first suing the guarantee trustee, the applicable trust or any other person or
entity.

                              PLAN OF DISTRIBUTION

    Sierra Pacific may sell the senior debt securities or subordinated debt
securities and the trusts may sell their preferred securities being offered
hereby in one or more of the following ways from time to time:

    - to underwriters for resale to the public or to institutional investors;

    - directly to institutional investors;

    - directly to agents;

    - through agents to the public or to institutional investors; or

    - if indicated in the prospectus supplement, pursuant to delayed delivery
      contracts, by remarketing firms or by other means.

    The prospectus supplements will set forth the terms of the offering of each
series of securities, including the name or names of any underwriters or agents,
the purchase price of the securities and the proceeds to Sierra Pacific or the
trusts, as the case may be, from the sale, any underwriting discounts or agency
fees and other items constituting underwriters' or agents' compensation, any
discounts or concessions allowed or reallowed or paid to dealers and any
securities exchanges on which the securities may be listed.

    If underwriters are utilized in the sale, the securities will be acquired by
the underwriters for their own account and may be resold from time to time in
one or more transactions, including negotiated transactions, at a fixed public
offering price or prices, which may be changed, or at market or varying prices
determined at the time of sale.

    Unless otherwise set forth in a prospectus supplement, the obligations of
the underwriters to purchase any series of securities will be subject to
conditions precedent and the underwriters will be obligated to purchase all of
the series of securities, if any are purchased.

                                       28
<PAGE>
    If a dealer is utilized in the sale of securities, Sierra Pacific or the
trusts will sell the securities to the dealer, as principal. The dealer may then
resell the securities to the public at varying prices to be determined by the
dealer at the time of resale.

    Securities may also be offered and sold, if so indicated in the prospectus
supplement, in connection with a remarketing agreement upon their purchase, in
accordance with a redemption or repayment pursuant to their terms, or otherwise,
by one or more firms ("remarketing firms") acting as principals for their own
accounts or as agents for Sierra Pacific. Any remarketing firm will be
identified and the terms of its agreement, if any, with Sierra Pacific and its
compensation will be described in the prospectus supplement.

    Underwriters, agents, dealers and remarketing firms may be entitled under
agreements entered into with Sierra Pacific and/or the trusts to indemnification
by Sierra Pacific and/or the trusts against civil liabilities, including
liabilities under the Securities Act of 1933, or to contribution with respect to
payments which the underwriters or agents may be required to make in respect
thereof. Underwriters, agents, dealers and remarketing firms may be customers
of, engage in transactions with, or perform services for Sierra Pacific and its
subsidiaries and affiliates in the ordinary course of business.

    Each series of securities will be a new issue of securities and will have no
established trading market. Any underwriters to whom securities are sold by
Sierra Pacific or by the trusts for public offering and sale may make a market
in the securities, but the underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. The securities may or
may not be listed on a national securities exchange or a foreign securities
exchange.

                                    EXPERTS

    The consolidated financial statements and the related financial statement
schedule incorporated in this prospectus by reference from Sierra Pacific's
Annual Report on Form 10-K have been audited by Deloitte & Touche LLP,
independent auditors, as stated in their reports, which are incorporated herein
by reference, and have been so incorporated in reliance upon the reports of such
firm given upon their authority as experts in accounting and auditing.

    With respect to the unaudited interim financial information of Sierra
Pacific, which is incorporated herein by reference, Deloitte & Touche LLP have
applied limited procedures in accordance with professional standards for a
review of such information. However, as stated in their report included in
Sierra Pacific's Quarterly Report on Form 10-Q and incorporated by reference
herein, they did not audit and they do not express an opinion on that interim
financial information. Accordingly, the degree of reliance on their report on
such information should be restricted in light of the limited nature of the
review procedures applied. Deloitte & Touche LLP are not subject to the
liability provisions of Section 11 of the Securities Act of 1933 for their
report on the unaudited interim financial information because that report is not
a "report" or a "part" of the registration statement prepared or certified by an
accountant within the meaning of Sections 7 and 11 of the Act.

    The consolidated financial statements and the related financial statement
schedule incorporated in this prospectus by reference from Nevada Power's Annual
Report on Form 10-K have been audited by Deloitte & Touche LLP, independent
auditors, as stated in their reports, which are incorporated herein by
reference, and have been so incorporated in reliance upon the reports of such
firm given their authority as experts in accounting and auditing.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Nevada Revised Statutes provide that under certain circumstances, a
corporation may indemnify any person for amounts incurred in connection with a
pending or threatened action, suit or proceeding in which he is, or is
threatened to be made, a party by reason of his being a director, officer,
employee or agent of the corporation.

    Sierra Pacific's Articles of Incorporation provides in substance that Sierra
Pacific will indemnify each of its directors and officers and former directors
and officers against expenses necessarily incurred in connection with the
defense of any action, suit or proceeding in which he or she is made a party by
reason of being or having been a director or officer of Sierra Pacific, except
in relation to matters as to which he or she shall be adjudged liable for
negligence or misconduct.

    Sierra Pacific has purchased insurance coverage under a policy insuring its
directors and officers against certain liabilities which they may incur in their
capacity as such.

    See "Item 17. Undertakings" for a description of the Securities and Exchange
Commission's position regarding such indemnification provisions.

ITEM 16. EXHIBITS

    See Index to Exhibits immediately preceding the Exhibits included as part of
this Registration Statement.

ITEM 17. UNDERTAKINGS

    The undersigned registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this Registration Statement:

           (i) To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933;

           (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the Registration Statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the Registration Statement;

                                      II-1
<PAGE>
           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in the Registration Statement or
       any material change to such information in the Registration Statement;

    PROVIDED, HOWEVER, that paragraphs (1)(i) and (1)(ii) do not apply if the
    Registration Statement is on Form S-3, Form S-8 or Form F-3, and the
    information required to be included in a post-effective amendment by those
    paragraphs is contained in periodic reports filed with or furnished to the
    Commission by the registrant pursuant to Section 13 or Section 15(d) of the
    Securities Exchange Act of 1934 that are incorporated by reference in the
    Registration Statement.

        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each post-effective amendment shall be deemed to be
    a new registration statement relating to the securities offered therein, and
    the offering of such securities at that time shall be deemed to be the
    initial bona fide offering thereof.

        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

    The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

for the equal and ratable benefit of the Holders of the Company's Securities
issued hereunder:

                                    RECITALS

         The Company has authorized the execution and delivery of this Indenture
to provide for the issuance from time to time of its unsecured debentures, notes
or other evidences of indebtedness ("Securities") to be issued in one or more

         For and in consideration of the premises and the purchase of the
Securities by the Holders thereof, it is mutually covenanted and agreed as
follows for the equal and ratable benefit of the Holders of the Securities:

                                   ARTICLE ONE
                   DEFINITIONS AND INCORPORATION BY REFERENCE

         Section 1.01.  DEFINITIONS.

         "Additional Amounts" means any additional amounts which are required by
a Security or by or pursuant to a Board Resolution, under circumstances
specified therein, to be paid by the Company in respect of certain taxes imposed
on Holders who are not United States Persons, or as otherwise specified in the
terms of a Security established pursuant to Section 2.01, and which are owing to
such Holders.

         "Agent" means any Registrar, Paying Agent or co-Registrar or agent for
service of notice and demands. See Section 2.03.

         "Affiliate" of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For the purposes of this definition,
"control" when used with respect to any specified Person means the power to
direct the management and policies of such Person, directly or indirectly,
whether through the ownership of voting securities, by contract or otherwise;
and the terms "controlling" and "controlled" have the meanings correlative to
the foregoing.

         "Authorized Newspaper" means a newspaper printed in the official

Securities is issued. Whenever, under the provisions of this Indenture or such
Board Resolutions, two or more publications of a notice or other

communication are required or permitted, such publications may be in the same or
different newspapers. If, because of temporary or permanent suspension of
publication or general circulation of any newspaper or for any other reason, it
is impossible or impracticable to publish any notices required by this Indenture
or a Board Resolution in the manner provided, then such publication in lieu
thereof or such other notice as shall be made with the approval of the Trustee
shall constitute a sufficient publication of such notice.

         "Bankruptcy Law" shall have the meaning set forth in Section 7.07.

         "Bearer Security" means any Security in the form established pursuant
to Section 2.01 which is payable to bearer.

                  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

                                       12

                  such Securities do not violate any rules, regulations or
                  orders of any governmental agency or commission having
                  jurisdiction over the Company.

         Section 2.03.  REGISTRAR AND PAYING AGENT.

         The Company shall designate a Registrar who shall maintain an office or
agency where Securities may be presented for registration of transfer and where
each series of Registered Securities may be presented for exchange ("Registrar")
and a Paying Agent who shall maintain an office or agency where Securities and
coupons may be presented for payment ("Paying Agent") and an office or agency
where notices and demands to or upon the Company in respect of the Securities
and this Indenture may be served. The Registrar shall keep a register ("Security
Register") of each series of Registered Securities and of their transfer and
exchange. The Company may have one or more co-Registrars and one or more
additional Paying Agents and shall maintain the Registrar or a co-Registrar and
a Paying Agent in each place required by Section 4.02. The term "Paying Agent"
includes any additional paying agent. In the event that the Trustee shall not be
the Registrar, it shall have the right to examine the Security Register at all
reasonable times.

         The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture. The agreement shall implement the
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 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.

                                       13

<PAGE>


         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.

         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

                                       14

<PAGE>


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 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 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

                                       15

<PAGE>


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

         The Company 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 SECURITIES.

         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

                                       16

<PAGE>


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.

         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 cancelled 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.

                                       17

<PAGE>


         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 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

                                       18

<PAGE>


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 cancelled Securities to the Company upon
Company Order, provided, however, that the Trustee may but shall not be required
to destroy cancelled Securities 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.

         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 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 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
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 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

                                       20

<PAGE>


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 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.

                                       21

<PAGE>


         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 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 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; and

                  (9) the CUSIP number, if any, of the Securities.

         At the Company's request, 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. Upon surrender to the Paying
Agent for such Securities of such Securities together with all unmatured
coupons, if any, 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.

         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.

                                       23

<PAGE>


         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 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.

                                    COVENANTS

         Section 4.01.  PAYMENT OF SECURITIES.

         The Company shall pay the principal of and any interest or Additional
Amounts, 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,
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, 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.

                                       24

<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

                                       25

<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, 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

                                       26

<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).

         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 ______ ___, 2000 (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.

         (b) The Company shall deliver to the Trustee, within thirty days after
the Company obtains knowledge of the occurrence thereof, written notice of any
Default.

         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. 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, 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

                                       28

<PAGE>


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.

                      SUCCESSOR CORPORATION AND ASSUMPTION

         Section 5.01.  WHEN COMPANY MAY MERGE, ETC.

         The Company shall not consolidate with or merge into, or sell, lease or
convey all or substantially all of its assets to, another Corporation unless the
successor or transferee Corporation 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

                                       29

<PAGE>


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.

                                   ARTICLE SIX
                              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

                                       30

<PAGE>


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, 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 Original Issue 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
Original Issue 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.

                                       31

<PAGE>


         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 Original Issue
Discount Securities) specified in the Securities of such series (or at the
respective rates of 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 Original Issue 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 Original Issue 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 or such Original Issue
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

                                       32

<PAGE>


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 Original Issue 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.

         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 Original Issue
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,

                                       33

<PAGE>


         (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 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

under Section 7.07.

         SECOND: to the Holders of Securities of such series or coupons
appertaining thereto for amounts due and unpaid on the Securities and coupons

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

                                       35

<PAGE>


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 default and of the continuance thereof, 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 no direction inconsistent with such written
request shall have been given to the Trustee, it being understood and intended,
and 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.

                                       36

<PAGE>


         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 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 forebearances 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 forebearances 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

                                       37

<PAGE>


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.

         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,

                                       38

<PAGE>


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.

         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.

                                     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 need perform only those duties that are
specifically set forth in this Indenture and no others.

                                       39

<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.

         (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.

         (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

         (h) 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.

         Section 7.02.  RIGHTS OF TRUSTEE.

         Except as provided in Section 7.01:

                                       40

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.

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

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.

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.

         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

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

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 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

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.

         Section 7.07.  COMPENSATION AND INDEMNITY.

         The Company shall pay to the Trustee from time to time such reasonable
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 against any loss damage claim,
expense or liability (including legal fees and

                                       42

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.

         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

                                       43

<PAGE>


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, 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.

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

         Section 7.10.  ELIGIBILITY; DISQUALIFICATION.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1). The Trustee shall have a combined capital
and surplus of at least $5,000,000 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.

                                  ARTICLE EIGHT
                             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

                                       44

<PAGE>


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;

                  (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

                                       45

<PAGE>


(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 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

                                       46

<PAGE>


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.

         Section 8.03.  APPLICATION OF TRUST MONEY.

         All moneys and Government Obligations deposited with the Trustee
pursuant to Sections 8.01 and 8.02 and, with respect to Government 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 Additional Amounts, if any, but such money
need not be segregated from other funds except to the extent required by law.

         Section 8.04.  REPAYMENT TO COMPANY.

         The Trustee and the Paying Agent shall promptly pay to the Company upon
request any excess money or securities held by them at any time under this
Article Eight. Any money deposited with the Trustee or 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
Obligations or the principal and interest received on such Government
Obligations.

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

         Section 9.01.  WITHOUT CONSENT OF HOLDERS.

         The Company, when authorized by a Board Resolution, and the Trustee may
amend or supplement this Indenture or the Securities without notice to or
consent of any Securityholder:

         (a)      to convey, transfer, assign, mortgage or pledge to the trustee
as security for the Securities of one or more series any property or assets;

         (b) to evidence the succession of another corporation to the Company,
or successive successions, and the assumption by the successor corporation of
the covenants, agreements and obligations of the Company pursuant to Article
Five;

         (c) to add to the covenants of the Company such further covenants,
restrictions, conditions or provisions as its Board of Directors and the Trustee
shall consider to be for the protection of the Holders of Securities or coupons
appertaining thereto, and to make the occurrence, or the occurrence and
continuance, of a default in any such additional covenants, restrictions,
conditions or provisions an Event of Default permitting the enforcement of all
or any of the several remedies provided in this Indenture as herein set forth;
provided, that in respect of any such 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 principal amount of the Securities of such series to waive
such an Event of Default.

         (d) to cure any ambiguity or to correct or supplement any provision
contained herein or in any supplemental indenture which may be defective or
inconsistent with any other provision contained herein or in any supplemental
indenture, or to make any other provisions as the Board of Directors may deem
necessary or desirable, provided that no such action shall adversely affect the
interests of the Holders of the Securities or coupons appertaining thereto;

the coupons appertaining to such Securities as permitted by Section 2.01;

United States) on the payment of principal of any premium or interest on Bearer
Securities, to permit Bearer Securities to be issued in exchange for

                                       48

<PAGE>


Registered Securities, to permit Bearer Securities to be issued in exchange for
Bearer Securities of other authorized denominations or to permit the issuance of
Securities in uncertificated form, provided that any such actions shall not
adversely affect the interest of the Holders of the Securities of any series or
any related coupons in any material respect; or

         (h) to add to, change or eliminate any of the provisions of this
Indenture (which addition, change or elimination may apply to one or more series
of Securities), provided that any such addition, change or elimination shall
neither (A) apply to any Security or any series created 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 consent
to an amendment, supplement or waiver or reduce the requirements of Section
11.09 establishing a quorum or voting or amend this Section 9.02;

of any Security;

                                                        49

                  (4) modify or effect in any manner adverse to the Holders of
Securities the terms and conditions of the obligations of the Company in respect
of its obligations hereunder;

                  (5) waive a default in the payment of the principal of or
interest or Additional Amounts, if any, on any Security;

                  (6) impair the right to institute suit for the enforcement of
any payment on or with respect to any series of Securities;

                  (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 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.

         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.

         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.

                                   ARTICLE TEN
                       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 cancelled. 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

                                       51

<PAGE>


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.

                         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 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 acknowledgements 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

                                       52

<PAGE>


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 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

                                                        53

<PAGE>


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.

         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 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

                                       54

<PAGE>


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

                                       55

<PAGE>


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 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.

                                       56

<PAGE>


         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 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

                                       57

<PAGE>


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.

                                  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.

         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

                                       58

<PAGE>


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 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.

         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

         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.

         Any request, demand, authorization, direction, notice, consent,
election or waiver required or permitted under this Indenture shall be in the
English language, except that, if the Company so elects, any published notice
may be in an official language of the country of publication.

         Section 13.03.  COMMUNICATION BY HOLDERS WITH OTHER HOLDERS.

         Securityholders may communicate pursuant to TIA Section 312(b) with
other Securityholders with respect to their rights under this Indenture or the

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:

         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 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.

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.

                            SIERRA PACIFIC RESOURCES

                                [-]% Note due [-]


         This Note is one of a duly authorized issue of Securities of the
Company of a series hereinafter specified, all issued and to be issued under an
Indenture dated as of [-] (herein called the "Indenture"), between the Company
and [-], as Trustee (herein called the "Trustee", which term includes any

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 Holder of the Securities and the terms upon which the
Securities are, and are to be, authenticated and delivered. The Securities may
be issued in one or more series, the terms of which different series may vary as
provided in the Indenture. This Note is one of a series of the Securities of the
Company designated as its [-]% Notes due [-] (herein called the "Notes"),
limited in aggregate principal amount to $[-], except as otherwise provided in
the Indenture.

         The Notes are not redeemable prior to maturity and are not entitled to
any sinking fund. If an Event of Default shall occur with respect to the Notes,
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 for defeasance at any time of the
Notes, upon which the Company, at its option, shall be deemed to have been
Discharged from its obligations with respect to the Notes or shall cease to be
under any obligation to comply with certain restrictive covenants of the
Indenture.

         Subject to certain exceptions, the Indenture or the Notes may be
amended or supplemented with the consent of the Holders of at least a majority
in principal amount of the Outstanding Securities affected by such amendment or
supplement voting as one class. Without the consent of any Holder, the Company
and the Trustee may amend or supplement the Indenture or the Notes to, among
other things, cure any ambiguity, defect or inconsistency. Subject to certain
exceptions, any past default or Event of Default may be waived by the Holders of
at least a majority in principal amount of the Outstanding Securities of any
series affected on behalf of the Holders of the Securities or that series or the
Holders of at least a majority in principal amount of all the Outstanding
Securities voting as one class. 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 Note issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Note or upon any Note issued upon the transfer hereof
or in exchange herefor or in lieu hereof.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the


                                        4

principal of, and interest on, this Note at the times, place, and rate, and in
the coin or currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, this Note is transferable on the Security Register of the Company,
upon surrender of this Note for transfer at the office or agency of the Company
in The City of New York, New York, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Registrar,
duly executed by the Holder hereof or his attorney duly authorized in writing,
and thereupon one or more new Notes, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

         The Notes are issuable in registered form without coupons in
denominations of [-] and integral multiples thereof. As provided in the
Indenture and subject to certain limitations therein set forth, this Note is
exchangeable for a like aggregate principal amount of Notes of different
authorized denominations as requested by the Holder surrendering the same.

         No service charge will be made for any such transfer or exchange, but
the Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the person in whose name this Note is registered as the owner hereof
for the purpose of receiving payment as herein provided and for all other
purposes whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         No recourse shall be had for the payment of the principal of, or the
interest on, this Note or for any claim based hereon or otherwise in any manner
in respect hereof, or in respect of the Indenture, against any incorporator,
shareholder, officer or director, as such, past, present or future, of the
Company or of any predecessor or successor corporation, whether by virtue of any
constitutional provision or statue or rule of law, or by the enforcement of any
assessment or penalty or in any other manner, all such liability being expressly
waived and released by the acceptance hereof and as part of the consideration
for the issue hereof.

Indenture shall have the meanings assigned to them in the Indenture.

evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such

certificate or affidavit shall also constitute sufficient proof of his
authority.

                  (c) The fact and date of the execution by any Person of any
such instrument or writing, or the authority of the Person executing the same,
may also be proved in any other manner which the Trustee deems sufficient and in

Securities Register.

                  (e) Any request, demand, authorization, direction, notice,

future Holder of the same Security and the Holder of every Security issued upon
the transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done 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.

                  (f) The Company may, but shall not be obligated to, fix a
record date for the purpose of determining the Holders entitled to take any
action under this Indenture by vote or consent. Except as otherwise provided
herein, 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
Securityholders furnished to the Trustee pursuant to Section 7.1 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 Holders
after such record date, provided, however, that unless such vote or consent is
obtained from the Holders (or their duly designated proxies) of the requisite
principal amount of Outstanding Securities prior to the date which is the 120th
day after such record date, any such vote or consent previously given shall
automatically and without further action by any Holder be cancelled and of no
further effect.

sufficient for every purpose (except as otherwise provided in Section 5.1
hereof) hereunder if in writing and mailed, first class, postage prepaid, to the
Company addressed to it at the address of its principal office specified in the
first paragraph of this instrument or at any other address previously furnished

         Section 1.6       NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first class postage prepaid, to each Holder affected
by such event, at the address of such Holder as it appears in the Securities
Register, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

shall control.

invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on the date the payment was originally payable. A "Business Day" shall mean any
day other than (i) a Saturday or Sunday, (ii) a day on which banking
institutions in the City of New York are authorized or required by law or
executive order to remain closed or (iii) a day on which the Corporate Trust
Office of the Trustee is closed for business. The interest installment so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in the Indenture, be paid to the Person in whose name this
Security (or one or more Predecessor Securities, as defined in the Indenture) is
registered at the close of business on the Regular Record Date for such interest
installment, which shall be the [[insert definition of Regular Record Dates].
Any such interest installment not so punctually paid or duly provided for shall
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

         [If applicable, insert The Company shall have the right at any time
during the term of this Security, from time to time, to defer payment of
interest on such Security for up to consecutive [monthly] [quarterly]
[semi-annual] interest payment periods with respect to each deferral period
(each an "Extension Period"), during which Extension Periods the Company shall
have the right to make partial payments of interest on any Interest Payment
Date, and at the end of which the Company shall pay all interest then accrued
and unpaid (together with Additional Interest thereon to the extent permitted by
applicable law); [provided that during any such Extension Period, the Company
will not, and will not permit any Subsidiary of the Company to, (i) declare or
pay any dividends or distributions or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Company's outstanding capital
stock or (ii) make any payment of principal of, interest or premium, if any, on
or repay, repurchase or redeem any debt security of the Company that ranks pari
passu with or junior in interest to this Security or make any

                                       15

guarantee payments with respect to any guarantee by the Company of the debt
securities of any subsidiaries of the Company if such guarantee ranks pari passu
or junior in interest to this Security (other than (a) dividends or
distributions in Common Stock of the Company, (b) redemptions or purchases of
any rights pursuant to the Company's Rights Plan, or any successor to such
Rights Plan, and the declaration of a dividend of such rights or the issuance of
Stock under such plans in the future, (c) payments under any Sierra Pacific
Guarantee (as defined in the Indenture), and (d) purchases of Common Stock
related to the issuance of Common Stock under any of the Company's benefit plans
for its directors, officers or employees.] Prior to the termination of any such
Extension Period, the Company may further extend the interest payment period,
provided that no Extension Period shall exceed consecutive [months] [quarters]
[semi-annual periods] or extend beyond the Maturity of this Security. Upon the
termination of any such Extension Period and upon the payment of all accrued and
unpaid interest and any Additional Interest then due, the Company may elect to
begin a new Extension Period, subject to the above requirements. No interest
shall be due and payable during an Extension Period except at the end thereof.
The Company shall give the Holder of this Security and the Trustee notice of its
election to begin any Extension Period at least one Business Day prior to the
Interest Payment Date [if applicable, insert or, with respect to the Securities
issued to a Sierra Pacific Trust, prior to the earlier of (i) the date the
Distributions on the Preferred Securities are payable or (ii) the date the
Administrative Trustees are required to give notice to any securities exchange
or other applicable self-regulatory organization or to holders of such Preferred
Securities of the record date or the date such Distributions are payable, but in
any event not less than one Business Day prior to such record date].

         Payment of the principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in the United States, 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 [if applicable, insert ; provided, however, that at the option of
the Company payment of interest may be made (i) by check mailed to the address
of the Person entitled thereto as such address shall appear in the Securities
Register or (ii) by wire transfer in immediately available funds at such place
and to such account as may be designated by the Person entitled thereto as
specified in the Securities Register].

         The indebtedness evidenced by this Security is, to the extent provided
in the Indenture, subordinate and subject in right of payments to the prior
payment in full of all Senior Debt, and this Security is issued subject to the
provisions of the Indenture with respect thereto. Each Holder of this Security,
by accepting the same, (a) agrees to and shall be bound by such provisions, (b)
authorizes and directs the Trustee on his behalf to take such actions as may be
necessary or appropriate to effectuate the subordination so provided and (c)
appoints the Trustee his attorney-in-fact for any and all such purposes. Each
Holder hereof, by his acceptance hereof, waives all notice of the acceptance of
the subordination provisions contained herein and in the Indenture by each
holder of Senior Debt, whether now outstanding or hereafter incurred, and waives
reliance by each such holder upon said provisions.

Company (herein called the "Securities"), issued and to be issued in one or more
series under a Junior Subordinated Indenture, dated as of [ ] (herein called the
"Indenture"), between the Company and [ ], 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 Trustee, the Company and the Holders of the
Securities, and of the terms upon which the Securities are, and are to be,

applicable, insert including Additional Interest, if any] to the date fixed for
redemption.]

         [If applicable, insert If a Special Event in respect of a Sierra
Pacific Trust shall occur and be continuing, the Company may, at its option,
redeem this Security within 90 days of the occurrence of such Special Event, in

provisions of Article Eleven of the Indenture, at a redemption price equal to
100% of the principal amount thereof plus accrued and unpaid interest, including
Additional Interest, if any, to the date fixed for redemption.]

         In the event of redemption of this Security in part only, a new
Security or Securities of this series for the unredeemed portion hereof will be
issued in the name of the Holder hereof upon the cancellation hereof.

         [If the Security is not a Discount Security: If an Event of Default
with respect to Securities of this series shall occur and be continuing, the
principal of this Security may be declared due and payable in the manner, with
the effect and subject to the conditions provided in the Indenture.]

         [If the Security is a Discount Security: If an Event of Default with
respect to Securities of this series shall occur and be continuing, an amount of

defeasance at any time of the entire indebtedness of this Security upon
compliance by the Company with certain conditions set forth in the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
Company and the Trustee at any time to enter into a supplemental indenture or
indentures for the purpose of modifying in any manner the rights and obligations
of the Company and of the Holders of the Securities, with the consent of the
Holders of not less than a majority in principal amount of the Outstanding
Securities of each series to be affected by such supplemental indenture. The
Indenture also contains provisions permitting Holders of specified percentages
in principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, 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 Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the

by Holders), provided that, in the case of the Securities of this series issued
to a Sierra Pacific Trust, if upon an Event of Default, the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of this series fails to declare the principal of all the Securities of this
series to be immediately due and payable, the holders of at least 25% in
aggregate liquidation amount of the corresponding series of Preferred Securities
then outstanding shall have such right by a notice in writing to the Company and
the Trustee; and upon any such declaration such specified amount of and the
accrued interest (including any Additional Interest) on all the Securities of
this series shall become immediately due and payable, provided that the payment
of principal and interest (including any Additional Interest) on such Securities
shall remain subordinated to the extend provided that the payment of principal
and interest (including any Additional Interest) on such Securities shall remain
subordinated to the extent provided in Article 13 of the Indenture.]

the provisions of the Indenture, if an Event of Default with respect to the
Securities of this series at the time Outstanding occurs and is continuing, then
and in every such case the Trustee or the Holders of not less than such portion
of the principal amount as may be specified in the terms of this series of all
the Securities of this series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders), provided that,
in the case of the Securities of this series issued to a Sierra Pacific Trust,
if upon an Event of Default, the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of this series fails to declare
the principal of all the Securities of this series to be immediately due and
payable, the holders of at least 25% in aggregate liquidation amount of the
corresponding series of Preferred Securities then outstanding shall have such
right by a notice in writing to the Company and the Trustee; and upon any such
declaration such specified amount of and the accrued interest (including any
Additional Interest) on all the Securities of this series shall become
immediately due and payable, provided that the payment of principal and interest
(including any Additional Interest) on such Securities shall remain subordinated
to the extent provided in Article Thirteen of the Indenture.]

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security at the times, place and rate, and in the coin or

such Securities;

provided, however, that the Trustee shall be entitled to receive the documents
referred to in Clauses (b), (c) and (d) above only at or prior to the first
request of the Company to the Trustee to authenticate Securities of such series.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
officers, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder.

         Section 3.4       TEMPORARY SECURITIES.

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

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

         Section 3.5       REGISTRATION, TRANSFER AND EXCHANGE.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Securities and of
transfers of Securities. Such register is herein

                                       25

<PAGE>


sometimes referred to as the "Securities Register." The Trustee is hereby
appointed "Securities Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

         Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated for that purpose the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series of any authorized denominations, of a like aggregate principal amount, of
the same Original Issue Date and Stated Maturity and having the same terms.

         At the option of the Holder, Securities may be exchanged for other
Securities of the same series of any authorized denominations, of a like
aggregate principal amount, of the same Original Issue Date and Stated Maturity
and having the same terms, upon surrender of the Securities to be exchanged at
such office or agency. Whenever any securities are so surrendered for exchange,
the Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

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

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

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

         Notwithstanding any of the foregoing, any Global Security of a series
shall be exchangeable pursuant to this Section 3.5 for Securities registered in
the names of Persons other than the Depositary for such Security or its nominee
only if (i) such Depositary notifies the Company that it is unwilling or unable
to continue as Depositary for such Global Security or if at any time such
Depositary ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, (ii) the Company executes and delivers to the
Trustee a Company Order that such Global Security shall be so exchangeable or
(iii) there shall have occurred and be continuing an Event of Default with
respect to the Securities of such series. Any Global Security that is
exchangeable pursuant to the preceding sentence shall be exchangeable for
Securities registered in such names as such Depositary shall direct.

         Notwithstanding any other provision in this Indenture, a Global
Security may not be transferred except as a whole by the Depositary with respect
to such Global Security to a

                                       26

<PAGE>


nominee of such Depositary or by a nominee of such Depositary to such Depositary
or another nominee of such Depositary.

         Neither the Company nor the Trustee shall be required, pursuant to the
provisions of this Section, (a) to issue, transfer or exchange any Security of
any series during a period beginning at the opening of business 15 days before
the day of selection for redemption of Securities pursuant to Article Eleven and
ending at the close of business on the day of mailing of notice of redemption or
(b) to transfer or exchange any Security so selected for redemption in whole or
in part, except, in the case of any Security to be redeemed in part, any portion
thereof not to be redeemed.

         Section 3.6       MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

         If any mutilated Security is surrendered to the Trustee together with
such security or indemnity as may be required by the Company or the Trustee to
save each of them harmless, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same issue
and series of like tenor and principal amount, having the same Original Issue
Date and Stated Maturity and bearing the same Interest Rate as such mutilated
Security, and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security, and (ii) such security or indemnity as may be required by them to save
each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
issuing Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same issue and series of like tenor and
principal amount, having the same Original Issue Date and Stated Maturity and
bearing the same Interest Rate as such destroyed, lost or stolen Security, and
bearing a number not contemporaneously outstanding.

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

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

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

                                       27

<PAGE>


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

         Section 3.7       PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Interest on any Security of any series which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date, shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest in respect of Securities of such series, except that, unless
otherwise provided in the Securities of such series, interest payable on the
Stated Maturity of a Security shall be paid to the Person to whom principal is
paid. The initial payment of interest on any Security of any series which is
issued between a Regular Record Date and the related Interest Payment Date shall
be payable as provided in such Security or in the Board Resolution pursuant to
Section 3.1 with respect to the related series of Securities.

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

                  (1) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Securities of such series in respect
of which interest is in default (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Security and the date of the proposed payment, and
at the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit
prior to the date of the proposed payment, such money when deposited to be held
in trust for the benefit of the Persons entitled to such Defaulted Interest as
in this Clause provided. Thereupon the Trustee shall fix a Special Record Date
for the payment of such Defaulted Interest which shall be not more than 15 days
and not less than 10 days prior to the date of the proposed payment and not less
than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first class, postage prepaid, to each Holder of a
Security of such series at the address of such Holder as it appears in the
Securities Register not less than 10 days prior to such Special Record Date. The
Trustee may, in its discretion, in the name and at the expense of the Company,
cause a similar notice to be published at least once in a newspaper, customarily
published in the English language on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, but such
publication shall not be a condition precedent to the establishment of

                                       28

<PAGE>


such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been mailed as aforesaid,
such Defaulted Interest shall be paid to the Persons in whose names the
Securities of such series (or their respective Predecessor Securities) are
registered on such Special Record Date and shall no longer be payable pursuant
to the following Clause (2).

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

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

         Section 3.8       PERSONS DEEMED OWNERS.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name any Security is registered as the owner of
such Security for the purpose of receiving payment of principal of and (subject
to Section 3.7) interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.

         Section 3.9       CANCELLATION.

         All Securities surrendered for payment, redemption, transfer or
exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee, and any such Securities and Securities surrendered
directly to the Trustee for any such purpose shall be promptly canceled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly canceled by the Trustee. No Securities shall be authenticated
in lieu of or in exchange for any Securities canceled as provided in this
Section, except as expressly permitted by this Indenture. All canceled
Securities shall be destroyed by the Trustee and the Trustee shall deliver to
the Company a certificate of such destruction.

         Section 3.10      COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 3.1 for
Securities of any series, interest on the Securities of each series for any
period shall be computed on the basis of a 360- day year of twelve 30-day months
and interest on the Securities of each series for any partial

                                       29

<PAGE>


period shall be computed on the basis of the number of days elapsed in a 360-day
year of twelve 30-day months.

         Section 3.11      DEFERRALS OF INTEREST PAYMENT DATES.

         If specified as contemplated by Section 3.1 with respect to the
Securities of a particular series, the Company shall have the right, at any time
during the term of such series, from time to time to defer the payment of
interest on such Securities for such period or periods as may be specified as
contemplated by Section 3.1 (each, an "Extension Period") during which Extension
Periods the Company shall have the right to make partial payments of interest on
any Interest Payment Date. No Extension Period shall end on a date other than an
Interest Payment Date. At the end of any such Extension Period the Company shall
pay all interest then accrued and unpaid on the Securities (together with
Additional Interest thereon, if any, at the rate specified for the Securities of
such series to the extent permitted by applicable law), provided, however, that
during any such Extension Period, [the Company shall not, and shall cause any
Subsidiary not to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
the Company's capital stock, or (ii) make any payment of principal, interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank pari passu with or junior in interest to the Securities of
such series or make any guarantee payments with respect to any Guarantee by the
Company of the debt securities of any Subsidiary of the Company that by their
terms rank pari passu or junior in interest to the securities of such series
(other than (a) dividends or distributions in common stock of the Company (b)
redemptions or purchases of any rights pursuant to the Company's Rights Plan, or
any successor to such Rights Plan, and the declaration of a dividend of such
rights or the issuance of stock under such plans in the future, (c) payments
under any Sierra Pacific Guarantee), and (d) purchases of Common Stock related
to the issuance of Common Stock under any of the Company's benefit plans for its
directors, officers or employees.] Prior to the termination of any such
Extension Period, the Company may further extend the interest payment period,
provided that no Extension Period shall exceed the period or periods specified
in such Securities or extend beyond the Maturity of such Securities. Upon
termination of any Extension Period and upon the payment of all accrued and
unpaid interest and any Additional Interest then due on any Interest Payment
Date, the Company may elect to begin a new Extension Period, subject to the
above requirements. No interest shall be due and payable during an Extension
Period, except at the end thereof. The Company shall give the Holders of the
Securities of such series and the Trustee notice of its election to begin any
such Extension Period at least one Business Day prior to the Interest Payment
Date or, with respect to the Securities of a series issued to a Sierra Pacific
Trust, prior to the earlier of (i) the date the Distributions on the Preferred
Securities of such Sierra Pacific Trust are payable or (ii) the date the
Administrative Trustees of such Sierra Pacific Trust are required to give notice
to any securities exchange or other applicable self-regulatory organization or
to holders of such Preferred Securities of the record date or the date such
Distributions are payable, but in any event not less than one Business Day prior
to such record date.

                                       30

<PAGE>


         The Trustee shall promptly give notice of the Company's election to
begin any such Extension Period to the Holders of the outstanding Securities of
such series.

         Section 3.12      RIGHT OF SET-OFF.

         With respect to the Securities of a series issued to a Sierra Pacific
Trust, notwithstanding anything to the contrary in the Indenture, the Company
shall have the right to set-off any payment it is otherwise required to make
thereunder in respect of any such Security to the extent the Company has
theretofore made, or is concurrently on the date of such payment making, a
payment under the Sierra Pacific Guarantee relating to such Security or under
Section 5.8 of the Indenture.

         Section 3.13      AGREED TAX TREATMENT.

         Each Security issued hereunder shall provide that the Company and, by
its acceptance of a Security or a beneficial interest therein, the Holder of,
and any Person that acquires a beneficial interest in, such Security agree that
for United States Federal, state and local tax purposes it is intended that such
Security constitute indebtedness.

         Section 3.14      EXTENSION OF STATED MATURITY; ADJUSTMENT OF STATED
                           MATURITY UPON AN EXCHANGE.

         If specified as contemplated by Section 3.1 with respect to the
Securities of a particular series, the Company shall have the right to (a)
change the Maturity Date of the Securities of such series upon the liquidation
of a Sierra Pacific Trust and the exchange of such Securities for the Preferred
Securities of such Sierra Pacific Trust and (b) extend the Stated Maturity for
the Securities of such series; provided, that at time any election to extend the
Maturity Date is made and at the time of such extension, (i) the Company is not
in bankruptcy, otherwise insolvent or in liquidation, (ii) the Company is not in
default in the payment of any interest or principal on the Securities of such
series and no deferred interest payments thereon have accrued, (iii) the
applicable Sierra Pacific Trust is not in arrears on payments of Distributions
on its Preferred Securities and no deferred Distributions thereon are
accumulated, (iv) the Securities are rated not less than BBB- by Standard &
Poor's Ratings Services or Baa3 by Moody's Investors Service, Inc. or the
equivalent by any other naturally recognized statistical rating organization and
(v) the extended Stated Maturity is no later than the 49th anniversary of the
initial issuance of the Preferred Securities of the applicable Sierra Pacific
Trust; provided, further, that, if the Company exercises its right to liquidate
the Sierra Pacific Trust and exchange the Securities of such series for the
Preferred Securities of such Sierra Pacific Trust as specified in clause (a)
above, any changed Stated Maturity of the Securities of such series shall be no
earlier than the date that is five years after the issuance of the Preferred
Securities and no later than the date 30 years (plus an extended term of up to
an additional 19 years if the above-referenced conditions are satisfied) after
the date of the initial issuance of the Preferred Securities of the applicable
Sierra Pacific Trust.

         Section 3.15      CUSIP NUMBERS.

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


                                   ARTICLE IV.

                           SATISFACTION AND DISCHARGE

         Section 4.1       SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall cease to be of further effect (except as to (i)
any surviving rights of transfer, substitution and exchange of Securities, (ii)
rights hereunder of Holders to receive payments of principal of (and premium, if
any) and interest on the Securities and other rights, duties and obligations of
the Holders as beneficiaries hereof with respect to the amounts, if any,
deposited with the Trustee pursuant to this Article IV and (iii) the rights and
obligations of the Trustee hereunder), and the Trustee, on demand of and at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

                  (1)      either

                           (A) all Securities theretofore authenticated and
         delivered (other than (i) Securities which have been destroyed, lost or
         stolen and which have been replaced or paid as provided in Section 3.6
         and (ii) Securities for whose payment money has theretofore been
         deposited in trust or segregated and held in trust by the Company and
         thereafter repaid to the Company or discharged from such trust, as
         provided in Section 10.3) have been delivered to the Trustee for
         cancellation; or

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

                                    (i) have become due and payable, or

                                    (ii) will become due and payable at their
                  Stated Maturity within one year of the date of deposit,

and the Company, in the case of Clause (B) (i) or (B) (ii) above, has deposited
or caused to be deposited with the Trustee as trust funds in trust for such
purpose an amount in the currency or

                                       32

<PAGE>


currencies in which the Securities of such series are payable sufficient to pay
and discharge the entire indebtedness on such Securities not theretofore
delivered to the Trustee for cancellation, for principal (and premium, if any)
and interest (including any Additional Interest) to the date of such deposit (in
the case of Securities which have become due and payable) or to the Stated
Maturity;

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

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

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.3 shall survive.

         Section 4.2       APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 10.3, all
money deposited with the Trustee pursuant to Section 4.1 or money or Government
Obligations deposited with the Trustee pursuant to Section 4.3, or received by
the Trustee in respect of Government Obligations deposited with the Trustee
pursuant to Section 4.3, shall be held in trust and applied by the Trustee, in
accordance with the provisions of the Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium, if any) and interest for the
payment of which such money or obligations have been deposited with or received
by the Trustee; provided, however, such moneys need not be segregated from other
funds except to the extent required by law.

         Section 4.3       SATISFACTION, DISCHARGE AND DEFEASANCE OF SECURITIES
OF ANY SERIES.

         Unless otherwise provided in the Board Resolution adopted pursuant to
Section 3.1 establishing the terms of the Securities of any series, the Company
shall be deemed to have paid and discharged the entire indebtedness on all the
Outstanding Securities of any such series and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of such indebtedness, when

                  (1)      with respect to all Outstanding Securities of such
series,

                           (A) the Company has irrevocably deposited or caused
         to be irrevocably deposited with the Trustee as trust funds in trust
         for such purpose an amount sufficient to pay and discharge the entire
         indebtedness on all Outstanding Securities of such series for

                                       33

<PAGE>


         principal (and premium, if any) and interest (including any Additional
         Interest) to the Stated Maturity or any Redemption Date as contemplated
         by the penultimate paragraph of this Section 4.3, as the case may be;
         or

                           (B) the Company has irrevocably deposited or caused
         to be irrevocably deposited with the Trustee as obligations in trust
         for such purpose an amount of Government Obligations as will, in the
         written opinion of independent public accountants delivered to the
         Trustee, together with predetermined and certain income to accrue
         thereon, without consideration of any reinvestment thereof, be
         sufficient to pay and discharge when due the entire indebtedness on all
         Outstanding Securities of such series for principal (and premium, if
         any) and interest (including any Additional Interest) to the Stated
         Maturity or any Redemption Date as contemplated by the penultimate
         paragraph of this Section 4.3, as the case may be; and

                  (2) the Company has paid or caused to be paid all other sums
payable with respect to the Outstanding Securities of such series; and

                  (3) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of the
entire indebtedness on all Outstanding Securities of any such series have been
complied with.

         Any deposits with the Trustee referred to in Section 4.3(i) above shall
be irrevocable and shall be made under the terms of an escrow trust agreement in
form and substance reasonably satisfactory to the Trustee. If any Outstanding
Securities of such series are to be redeemed prior to their Stated Maturity,
whether pursuant to any optional redemption provisions or in accordance with any
mandatory sinking fund requirement, the applicable escrow trust agreement shall
provide therefor and the Company shall make such arrangements as are
satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Company. If the Securities of
such series are not to become due and payable at their Stated Maturity or upon
call for redemption within one year of the date of deposit, then the Company
shall give, not later than the date of such deposit, notice of such deposit to
the Holders of Securities of such series.

         Upon the satisfaction of the conditions set forth in this Section 4.3
with respect to all the Outstanding Securities of any series, the terms and
conditions of such series, including the terms and conditions with respect
thereto set forth in this Indenture, shall no longer be binding upon, or
applicable to, the Company; provided, that the Company shall not be discharged
from any payment obligations in respect of Securities of such series which are
deemed not to be Outstanding under clause (iii) of the definition thereof if
such obligations continue to be valid obligations of the Company under
applicable law.

                                    REMEDIES

         Section 5.1       EVENTS OF DEFAULT.

         "Event of Default", wherever used herein with respect to the Securities
of any series, means any one of the following events (whatever the reason for
such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body):

                  (1) default in the payment of any interest upon any Security
of that series, including any Additional Interest in respect thereof, when it
becomes due and payable, and continuance of such default for a period of 30 days
(subject to the deferral of any due date in the case of an Extension Period); or

                  (2) default in the payment of the principal of (or premium, if
any, on) any Security of that series at its Maturity; or

                  (3) default in the performance, or breach, in any material
respect, of any covenant or warranty of the Company in this Indenture (other
than a covenant or warranty a default in the performance of which or the breach
of which is elsewhere in this Section specifically dealt with), and continuance
of such default or breach for a period of 90 days after there has been given, by
registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of that series a written notice specifying such default
or breach and requiring it to be remedied; or

                  (4) the entry of a decree or order by a court having
jurisdiction in the premises adjudging the Company a bankrupt or insolvent, or
approving as properly filed a petition seeking reorganization, arrangement,
adjustment or composition of or in respect of the Company under any applicable
Federal or State bankruptcy, insolvency, reorganization or other similar law, or
appointing a receiver, liquidator, assignee, trustee, sequestrator (or other
similar official) of the Company or of any substantial part of its property or
ordering the winding up or liquidation of its affairs, and the continuance of
any such decree or order unstayed and in effect for a period of 60 consecutive
days; or

                  (5) the institution by the Company of proceedings to be
adjudicated a bankrupt or insolvent, or the consent by it to the institution of
bankruptcy or insolvency proceedings against it, or the filing by it of a
petition or answer or consent seeking reorganization or relief under any
applicable Federal or State bankruptcy, insolvency, reorganization or other
similar law, or the consent by it to the filing of any such petition or to the
appointment of a receiver, liquidator, assignee, trustee, sequestrator (or other
similar official) of

                                       35

<PAGE>


the Company or of any substantial part of its property, or the making by it of
an assignment for the benefit for creditors, or the admission by it in writing
of its inability to pay its debts generally as they become due and its
willingness to be adjudicated a bankrupt, or the taking of corporate action by
the Company in furtherance of any such action; or

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

         Section 5.2       ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
the Securities of that series are Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) of all the
Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders), provided that,
in the case of the Securities of a series issued to a Sierra Pacific Trust, if,
upon an Event of Default, the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of that series fail to declare
the principal of all the Securities of that series to be immediately due and
payable, the holders of at least 25% in aggregate liquidation amount of the
corresponding series of Preferred Securities then outstanding shall have such
right by a notice in writing to the Company and the Trustee; and upon any such
declaration such principal amount (or specified amount) of and the accrued
interest (including any Additional Interest) on all the Securities of such
series shall become immediately due and payable, provided that the payment of
principal and interest (including any Additional Interest) on such Securities
shall remain subordinated to the extent provided in Article Thirteen.

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

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

                           (A)      all overdue installments of interest
         (including any Additional Interest) on all Securities of that series,

                           (B) the principal of (and premium, if any, on) any
         Securities of that series which have become due otherwise than by such
         declaration of acceleration and interest thereon at the rate borne by
         the Securities, and

                                       36

<PAGE>


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

                  (2) all Events of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series
which has become due solely by such acceleration, have been cured or waived as
provided in Section 5.13.

         The holders of a majority in aggregate outstanding principal amount of
the Securities of a series affected thereby may, on behalf of the holders of all
the Securities of such series, waive any past default, except a default in the
payment of principal or interest (unless such default has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Trustee) or a default
in respect of a covenant or provision which under this Indenture cannot be
modified or amended without the consent of the holder of each outstanding
Security of such series and, in the case of Securities of a series issued to a
Sierra Pacific Trust, should the holders of such Securities fail to annul such
declaration and waive such default, the holders of a majority in aggregate
liquidation preference of the related series of Preferred Securities shall have
such right.

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

         Upon receipt by the Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, with respect to Securities of
a series all or part of which is represented by a Global Security, a record date
shall be established for determining Holders of Outstanding Securities of such
series entitled to join in such notice, which record date shall be at the close
of business on the day the Trustee receives such notice. The Holders on such
record date, or their duly designated proxies, and only such Persons, shall be
entitled to join in such notice, whether or not such Holders remain Holders
after such record date; provided, that, unless such declaration of acceleration,
or rescission and annulment, as the case may be, shall have become effective by
virtue of the requisite percentage having joined in such notice prior to the day
which is 90 days after such record date, such notice of declaration of
acceleration, or rescission and annulment, as the case may be, shall
automatically and without further action by any Holder be canceled and of no
further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of
a Holder, from giving, after expiration of such 90-day period, a new written
notice of declaration of acceleration, or rescission and annulment thereof, as
the case may be, that is identical to a written notice which has been canceled
pursuant to the proviso to the preceding sentence, in which event a new record
date shall be established pursuant to the provisions of this Section 5.2.

         Section 5.3       COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT
BY TRUSTEE.

         The Company covenants that if:

                                       37

<PAGE>


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

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

the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal, including any sinking fund payment or
analogous obligations (and premium, if any) and interest (including any
Additional Interest); and, in addition thereto, all amounts owing the Trustee
under Section 6.7.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

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

         Section 5.4       TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors,

                  (a) the Trustee (irrespective of whether the principal of the
Securities of any series shall then be due and payable as therein expressed or
by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal (and
premium, if any) or interest (including any Additional Interest)) shall be
entitled and empowered, by intervention in such proceeding or otherwise,

                                    (i) to file and prove a claim for the whole
                  amount of principal (and premium, if any) and interest
                  (including any Additional Interest) owing and unpaid in
                  respect to the Securities and to file such other papers or
                  documents as may be necessary or advisable and to take any and
                  all actions as are authorized

                                       38

<PAGE>


                  under the Trust Indenture Act in order to have the claims of
                  the Holders and any predecessor to the Trustee under Section
                  6.7 and of the Holders allowed in any such judicial
                  proceedings; and

                                    (ii) and in particular, the Trustee shall be
                  authorized to collect and receive any moneys or other property
                  payable or deliverable on any such claims and to distribute
                  the same in accordance with Section 5.6; and

                  (b) any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee for
distribution in accordance with Section 5.6, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it and any predecessor Trustee under Section 6.7.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

         Section 5.5       TRUSTEE MAY ENFORCE CLAIM WITHOUT POSSESSION OF
SECURITIES.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of all the amounts owing the Trustee and any
predecessor Trustee under Section 6.7, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

         Section 5.6       APPLICATION OF MONEY COLLECTED.

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

                  FIRST:  To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 6.7;

                                       39

<PAGE>


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

                  THIRD:  The balance, if any, to the Person or Persons entitled
thereto.

         Section 5.7       LIMITATION ON SUITS.

         No Holder of any Securities of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture
or for the appointment of a receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) or for any other remedy hereunder,
unless:

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

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

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

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

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

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

         Section 5.8       UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL,
                           PREMIUM AND INTEREST.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right which is absolute and unconditional to receive
payment of the principal of (and

                                       40

<PAGE>


premium, if any) and (subject to Section 3.7) interest (including any Additional
Interest) on such Security on the respective Stated Maturities expressed in such
Security and to institute suit for the enforcement of any such payment, and such
right shall not be impaired without the consent of such Holder. In the case of
Securities of a series issued to a Sierra Pacific Trust, any holder of the
corresponding series of Preferred Securities shall have the right, upon the
occurrence of an Event of Default described in Section 5.1(1) or 5.2(1) hereof,
to institute a suit directly against the Company for enforcement of payment to
such Holder of principal of (premium, if any) and (subject to Section 3.7)
interest (including any Additional Interest) on the Securities having a
principal amount equal to the aggregate liquidation preference of the Preferred
Securities of the corresponding series held by such Holder.

         Section 5.9       RESTORATION OF RIGHTS AND REMEDIES.

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

         Section 5.10      RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

         Section 5.11      DELAY OR OMISSION NOT WAIVER.

         Except as otherwise provided in the last paragraph of Section 3.6, no
delay or omission of the Trustee or of any Holder of any Security to exercise
any right or remedy accruing upon any Event of Default shall impair any such
right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein.

         Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

                                       41

<PAGE>


         Section 5.12      CONTROL BY HOLDERS.

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

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

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

                  (3) subject to the provisions of Section 6.1, the Trustee
shall have the right to decline to follow such direction if the Trustee in good
faith shall, by a Responsible Officer or Officers of the Trustee, determine that
the proceeding so directed would be unjustly prejudicial to the Holders not
joining in any such direction or would involve the Trustee in personal
liability.

         Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or exercising any such trust
or power, with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such notice, which record date shall be at the close of business on the day the
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that, unless the Holders of a majority in principal amount of the
Outstanding Securities of such series shall have joined in such notice prior to
the day which is 90 days after such record date, such notice shall automatically
and without further action by any Holder be canceled and of no further effect.
Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from
giving, after expiration of such 90-day period, a new notice identical to a
notice which has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 5.12.

         Section 5.13      WAIVER OF PAST DEFAULTS.

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

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

                                       42

<PAGE>


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

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

         Section 5.14      UNDERTAKING FOR COSTS.

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

         Section 5.15      WAIVER OF USURY, STAY OR EXTENSION LAWS.

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

                                   ARTICLE VI.

                                   THE TRUSTEE

         Section 6.1       CERTAIN DUTIES AND RESPONSIBILITIES.

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

                                       43

<PAGE>


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

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

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

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

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

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

                  (3) the Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with the
direction of Holders pursuant to Section 5.12 relating to the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee, under this Indenture
with respect to the Securities of such series.

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

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

         Within 90 days after actual knowledge by a Responsible Officer of the
Trustee of the occurrence of any default hereunder with respect to the
Securities of any series, the Trustee shall transmit by mail to all Holders of
Securities of such series, as their names and addresses appear in the Securities
Register, notice of such default hereunder known to the Trustee, unless such

such series; and provided, further, that, in the case of any default of the
character specified in Section 5.1(3), no such notice to Holders of Securities
of such series shall be given until at least 30 days after the occurrence
thereof. For the purpose of this Section, the term "default" means any event
which is, or after notice or lapse of time or both would become, an Event of

         Subject to the provisions of Section 6.1:

indenture, Security or other paper or document, but the Trustee in its
discretion may make such inquiry or investigation into such facts or matters as
it may see fit, and, if the Trustee shall determine to make such inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney; and

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

         Section 6.4       NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
SECURITIES.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. The Trustee shall not be accountable for the use
or application by the Company of the Securities or the proceeds thereof.

         Section 6.5       MAY HOLD SECURITIES.

         The Trustee, any Paying Agent, Securities Registrar or any other agent
of the Company, in its individual or any other capacity, may become the owner or
pledgee of Securities and, subject to Sections 6.8 and 6.13, may otherwise deal
with the Company with the same rights it would have if it were not Trustee,
Paying Agent, Securities Registrar or such other agent.

         Section 6.6       MONEY HELD IN TRUST.

                  (1) to pay to the Trustee from time to time reasonable

trustee of an express trust);

                                       46

<PAGE>


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

                  (3) to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense (including the reasonable compensation
and the expenses and disbursements of its agents and counsel) incurred without
negligence or bad faith, arising out of or in connection with the acceptance or
administration of this trust or the performance of its duties hereunder,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder. This indemnification shall survive the termination of this
Agreement.

         To secure the Company's payment obligations in this Section, the
Company and the Holders agree that the Trustee shall have a lien prior to the
Securities on all money or property held or collected by the Trustee. Such lien
shall survive the satisfaction and discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Reform Act of 1978 or a successor statute.

         The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act. Nothing
herein shall prevent the Trustee from filing with the Commission the application
referred to in the second to last paragraph of Section 301(b) of the Trust
Indenture Act.

         Section 6.9       CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

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

                  (a) a corporation organized and doing business under the laws
of the United States of America or of any State, Territory or the District of
Columbia, authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by Federal, State, Territorial or District
of Columbia authority, or

                  (b) a corporation or other Person organized and doing business
under the laws of a foreign government that is permitted to act as Trustee
pursuant to a rule, regulation or order of the Commission, authorized under such
laws to exercise corporate trust powers, and subject to supervision or
examination by authority of such foreign government or a political subdivision

                                       47

<PAGE>


thereof substantially equivalent to supervision or examination applicable to
United States institutional trustees,

in either case having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by Federal or State authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then,
for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article. Neither the Company nor any Person directly or indirectly
controlling, controlled by or under common control with the Company shall serve
as Trustee for the Securities of any series issued hereunder.

         Section 6.10      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

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

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

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

                  (d) If at any time:

                  (1) the Trustee shall fail to comply with Section 6.8 after
written request therefor by the Company or by any Holder who has been a bona
fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 6.9
and shall fail to resign after written request therefor by the Company or by any
such Holder, or

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

                                       48

<PAGE>


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

                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause with respect to the Securities of one or more series, the Company, by
a Board Resolution, shall promptly appoint a successor Trustee with respect to
the Securities of that or those series. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment, become the successor Trustee with respect to the Securities
of such series and supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Company or the Holders and accepted appointment in the
manner hereinafter provided, any Holder who has been a bona fide Holder of a
Security for at least six months may, subject to Section 5.14, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
by mailing written notice of such event by first-class mail, postage prepaid, to
the Holders of Securities of such series as their names and addresses appear in
the Securities Register. Each notice shall include the name of the successor
Trustee with respect to the Securities of such series and the address of its
Corporate Trust Office.

         Section 6.11      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

                  (b) In case of the appointment hereunder of a successor
Trustee with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each

                                       49

<PAGE>


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

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

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

         Section 6.12      MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS.

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

                                       50

<PAGE>


in the name of any predecessor Trustee or in the name of such successor Trustee,
and in all cases the certificate of authentication shall have the full force
which it is provided anywhere in the Securities or in this Indenture that the
certificate of the Trustee shall have.

         Section 6.13      PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

         Section 6.14      APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof,
and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States of America, or of any State, Territory or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or
examination by Federal or State authority. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

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

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the

                                       51

<PAGE>


Company. Upon receiving such a notice of resignation or upon such a termination,
or in case at any time such Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the Company and
shall give notice of such appointment in the manner provided in Section 1.6 to
all Holders of Securities of the series with respect to which such
Authenticating Agent will serve. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provision of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 6.7.

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

         This is one of the Securities referred to in the within mentioned
Indenture.

with respect to their rights under this Indenture or under the Securities, and
the corresponding rights and privileges of the Trustee, shall be as provided in
the Trust Indenture Act.

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

         Section 7.3       REPORTS BY TRUSTEE.

                  (a) The Trustee shall transmit to Holders such reports
concerning the Trustee and its actions under this Indenture as may be required
pursuant to the Trust Indenture Act, at the times and in the manner provided
pursuant thereto.

                  (b) Reports so required to be transmitted at stated intervals
of not more than 12 months shall be transmitted no later than July 15 in each

                  (c) A copy of each such report shall, at the time of such

notify the Trustee whenever the Securities are listed on any stock exchange.

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

times and in the manner provided in the Trust Indenture Act; provided that any
such information, documents or reports required to be filed with the Commission
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
shall be filed with the Trustee within 15 days after the same is required to be
filed with the Commission. Notwithstanding that the Company may not be required
to remain subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, the Company shall continue to file with the
Commission and provide the Trustee with the annual reports and the information,
documents and other reports which are specified in Sections 13 and

trust organized and existing under the laws of the United States of America or
any State or the District of Columbia, and shall expressly assume, by an
indenture supplemental hereto, executed and delivered to the Trustee, in form
satisfactory to the Trustee, the due and punctual payment of the principal of
(and premium, if any) and interest (including any Additional Interest) on all
the Securities and the performance of every covenant of this Indenture on the
part of the Company to be performed or observed;

                  (2) immediately after giving effect to such transaction, no
Event of Default, and no event which, after notice or lapse of time, or both,
would become an Event of Default, shall have happened and be continuing;

                  (3) in the case of the Securities of a series issued to a
Sierra Pacific Trust, such consolidation, merger, conveyance, transfer or lease
is permitted under the related Trust Agreement and Sierra Pacific Guarantee and
does not give rise to any breach or violation of the related Trust Agreement or
Sierra Pacific Guarantee; and

                  (4) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel each stating that such consolidation,
merger, conveyance, transfer or lease and any such supplemental indenture
complies with this Article and that all conditions precedent herein provided for
relating to such transaction have been complied with; and the Trustee, subject
to Section 6.1, may rely upon such Officers' Certificate and Opinion of Counsel
as conclusive evidence that such transaction complies with this Section 8.1.

         Section 8.2       SUCCESSOR CORPORATION SUBSTITUTED.

         Upon any consolidation or merger by the Company with or into any other
Person, or any conveyance, transfer or lease by the Company of its properties
and assets substantially as an entirety to any Person in accordance with Section
8.1, the successor corporation formed by such consolidation or into which the
Company is merged or to which such conveyance, transfer or lease is made shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under this Indenture with the same effect as if such successor
Person had been named as the Company herein; and in the event of any such
conveyance, transfer or lease the Company shall be discharged from all
obligations and covenants under the Indenture and the Securities and may be
dissolved and liquidated.

         Such successor Person may cause to be signed, and may issue either in
its own name or in the name of the Company, any or all of the Securities
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee; and, upon the order of such successor Person
instead of the Company and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver
any Securities which previously shall have been signed and delivered by the
officers of the Company to the Trustee for authentication pursuant to such
provisions and any Securities which such successor Person thereafter shall cause
to be signed and delivered to the Trustee on its behalf for the purpose pursuant
to such provisions. All the Securities so issued shall in all respects have the
same legal rank and benefit under this Indenture as the Securities theretofore
or thereafter issued in accordance with the terms of this Indenture as though
all of such Securities had been issued at the date of the execution hereof.

         In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form may be made in the Securities thereafter to
be issued as may be appropriate.

                                   ARTICLE IX.

                             SUPPLEMENTAL INDENTURES

         Section 9.1       SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.

         Without the consent of any Holders, the Company, when authorized by a
Board Resolution, and the Trustee, at any time and from time to time, may enter
into one or more indentures supplemental hereto, in form satisfactory to the
Trustee, for any of the following purposes:

                  (1) to evidence the succession of another Person to the
Company, and the assumption by any such successor of the covenants of the
Company herein and in the Securities contained; or

                                       55

<PAGE>


                  (2) to convey, transfer, assign, mortgage or pledge any
property to or with the Trustee or to surrender any right or power herein
conferred upon the Company; or

                  (3)      to establish the form or terms of Securities of any
series as permitted by Sections 2.1 or 3.1; or

                  (4) to add to the covenants of the Company for the benefit of
the Holders of all or any series of Securities (and if such covenants are to be
for the benefit of less than all series of Securities, stating that such
covenants are expressly being included solely for the benefit of such series) or
to surrender any right or power herein conferred upon the Company; or

                  (5)      to add any additional Events of Default; or

                  (6) to change or eliminate any of the provisions of this
Indenture, provided that any such change or elimination shall become effective
only when there is no Security Outstanding of any series created prior to the
execution of such supplemental indenture which is entitled to the benefit of
such provision; or

                  (7) to cure any ambiguity, to correct or supplement any
provision herein which may be inconsistent with any other provision herein, or
to make any other provisions with respect to matters or questions arising under
this Indenture, provided that such action pursuant to this clause (7) shall not
materially adversely affect the interest of the Holders of Securities of any
series or, in the case of the Securities of a series issued to a Sierra Pacific
Trust and for so long as any of the corresponding series of Preferred Securities
shall remain outstanding, the holders of such Preferred Securities; or

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

                  (9) to comply with the requirements of the Commission in order
to effect or maintain the qualification of this Indenture under the Trust
Indenture Act.

         Section 9.2       SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities

                                       56

<PAGE>


of such series under this Indenture; provided, however, that no such
supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby,

                  (1) except to the extent permitted by Section 3.11 or as
otherwise specified as contemplated by Section 3.1 with respect to the extension
of the interest payment period of the Securities of any series, change the
Stated Maturity of the principal of, or any installment of interest (including
any Additional Interest) on, any Security, or reduce the principal amount
thereof or the rate of interest thereon or reduce any premium payable upon the
redemption thereof, or reduce the amount of principal of a Discount Security
that would be due and payable upon a declaration of acceleration of the Maturity
thereof pursuant to Section 5.2, or change the place of payment where, or the
coin or currency in which, any Security or interest thereon is payable, or
impair the right to institute suit for the enforcement of any such payment on or
after the Stated Maturity thereof (or, in the case of redemption, on or after
the date fixed for redemption thereof), or

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

                  (3) modify any of the provisions of this Section, Section 5.13
or Section 10.5, except to increase any such percentage or to provide that
certain other provisions of this Indenture cannot be modified or waived without
the consent of the Holder of each Security affected thereby; or

                  (4) modify the provisions in Article Thirteen of this
Indenture with respect to the subordination of Outstanding Securities of any
series in a manner adverse to the Holders thereof;

provided that, in the case of the Securities of a series issued to a Sierra
Pacific Trust, so long as any of the corresponding series of Preferred
Securities remains outstanding, no such amendment shall be made that adversely
affects the holders of such Preferred Securities, and no termination of this
Indenture shall occur, and no waiver of any Event of Default or compliance with
any covenant under this Indenture shall be effective, without the prior consent
of the holders of at least a majority of the aggregate liquidation preference of
such Preferred Securities then outstanding unless and until the principal (and
premium, if any) of the Securities of such series and all accrued and, subject
to Section 3.7, unpaid interest (including any Additional Interest) thereon have
been paid in full; and provided further that in the case of the Securities of a
series issued to a Sierra Pacific Trust, so long as any of the corresponding
series of Preferred Securities remain outstanding, no amendment shall be made to
Section 5.8 of this Indenture without the prior consent of the holders of each
Preferred Security then outstanding unless and until the principal (and premium,
if any) of the Securities of such series and all accrued and (subject to Section
3.7) unpaid interest (including any Additional Interest) thereon have been paid
in full.

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

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

         Section 9.3       EXECUTION OF SUPPLEMENTAL INDENTURES.

         In executing or accepting the additional trusts created by any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 6.1) shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture, and
that all conditions precedent have been complied with. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

         Section 9.4       EFFECT OF SUPPLEMENTAL INDENTURES.

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

         Section 9.5       CONFORMITY WITH TRUST INDENTURE ACT.

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

         Section 9.6       REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

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

                                   ARTICLE X.

                                    COVENANTS

         Section 10.1      PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

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

         Section 10.2      MAINTENANCE OF OFFICE OR AGENCY.

         The Company will maintain in each Place of Payment for any series, an
office or agency where Securities of that series may be presented or surrendered
for payment and an office or agency where Securities may be surrendered for
transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities and this Indenture may be served. The Company
initially appoints the Trustee, acting through its Corporate Trust Office, as
its agent for said purposes. The Company will give prompt written notice to the
Trustee of any change in the location of any such office or agency. If at any
time the Company shall fail to maintain such 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, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all of 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 and any
change in the location of any such office or agency.

         Section 10.3      MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST.

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

         Whenever the Company shall have one or more Paying Agents, it will,
prior to 10:00 a.m. New York City time on each due date of the principal of or
interest on any Securities, deposit with a Paying Agent a sum sufficient to pay
the principal (and premium, if any) or

                                       59

<PAGE>


interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal and premium (if any) or interest, and (unless
such Paying Agent is the Trustee) the Company will promptly notify the Trustee
of its failure so to act.

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

                  (1) hold all sums held by it for the payment of the principal
of (and premium, if any) or interest on Securities 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 (or
any other obligor upon the Securities) in the making of any payment of principal
(and premium, if any) or interest;

                  (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; and

                  (4)      comply with the provisions of the Trust Indenture Act
applicable to it as a Paying Agent.

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

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall (unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be paid on Company Request to the Company,
or (if then held by the Company) shall (unless otherwise required by mandatory
provision of applicable escheat or abandoned or unclaimed property law) be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business

                                       60

<PAGE>


Day and of general circulation in the Borough of Manhattan, the City of New
York, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Company.

         Section 10.4      STATEMENT AS TO COMPLIANCE.

         The Company shall deliver to the Trustee, within 120 days after the end
of each calendar year of the Company ending after the date hereof, an Officers'
Certificate covering the preceding calendar year, stating whether or not to the
best knowledge of the signers thereof the Company is in default in the
performance, observance or fulfillment of or compliance with any of the terms,
provisions, covenants and conditions of this Indenture, and if the Company shall
be in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge. For the purpose of this Section 10.4, compliance
shall be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

         Section 10.5      WAIVER OF CERTAIN COVENANTS.

         The Company may omit in any particular instance to comply with any
covenant or condition as specified as contemplated by Section 3.1 with respect
to the Securities of any series, if before or after the time for such compliance
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive 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 in respect of any such covenant
or condition shall remain in full force and effect.

         Section 10.6      ADDITIONAL SUMS.

         In the case of the Securities of a series issued to a Sierra Pacific
Trust, except as otherwise specified as contemplated by Section 3.1, in the
event that (i) a Sierra Pacific Trust is the Holder of all of the Outstanding
Securities of such series, (ii) a Trust Tax Event in respect of such Sierra
Pacific Trust shall have occurred and be continuing and (iii) the Company shall
not have (i) redeemed the Securities of such series pursuant to Section 11.7(b)
or (ii) terminated such Sierra Pacific Trust pursuant to Section 9.2(b) of the
related Trust Agreement, the Company shall pay to such Sierra Pacific Trust (and
its permitted successors or assigns under the related Trust Agreement) for so
long as such Sierra Pacific Trust (or its permitted successor or assignee) is
the registered holder of any Securities of such series, such additional amounts
as may be necessary in order that the amount of distributions (including any
Additional Amounts (as defined in the Trust Agreement)) then due and payable by
such Sierra Pacific Trust on the related Preferred Securities and Common
Securities that at any time remain outstanding in accordance with the terms
thereof shall not be reduced as a result of any Additional Taxes (the
"Additional Sums"). Whenever in this Indenture or the Securities there is a
reference in any context to the payment of principal of or interest on the
Securities, such mention shall be deemed

                                       61

<PAGE>


to include mention of the payments of the Additional Sums provided for in this
paragraph to the extent that, in such context, Additional Sums are, were or
would be payable in respect thereof pursuant to the provisions of this paragraph
and express mention of the payment of Additional Sums (if applicable) in any
provisions hereof shall not be construed as excluding Additional Sums in those
provisions hereof where such express mention is not made, provided, however,
that the extension of an interest payment period pursuant to Section 3.11 or the
Securities shall not extend the payment of any Additional Sums that may be due
and payable during such interest payment period.

         [Section 10.7     ADDITIONAL COVENANTS.

         The Company covenants and agrees with each Holder of Securities of a
series issued to a Sierra Pacific Trust that it will not, and it will not permit
any Subsidiary of the Company to, (a) declare or pay any dividends or
distributions on, or redeem purchase, acquire or make a liquidation payment with
respect to, any shares of the Company's capital stock, or (b) make any payment
of principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities of the Company that rank pari passu with or junior to the
Securities of such series or make any guarantee payments with respect to any
guarantee by the Company of debt securities of any subsidiary of the Company if
such guarantee ranks pari passu with or junior in interest to the Securities
(other than (a) dividends or distributions in Common Stock of the Company, (b)
redemptions or purchases of any rights pursuant to the Company's Rights Plan, or
any successor to such Rights Plan, and the declaration of a dividend of such
rights or the issuance of stock under such plans in the future, (c) payments
under any Sierra Pacific Guarantee, and (d) purchases of Common Stock related to
the issuance of Common Stock under any of the Company's benefit plans for its
directors, officers or employees) if at such time (i) there shall have occurred
any event of which the Company has actual knowledge that (a) with the giving of
notice or the lapse of time or both, would constitute an Event of Default
hereunder and (b) in respect of which the Company shall not have taken
reasonable steps to cure, (ii) the Company shall be in default with respect to
its payment of any obligations under the related Sierra Pacific Guarantee or
(iii) the Company shall have given notice of its election to begin an Extension
Period as provided herein and shall not have rescinded such notice, or such
period, or any extension thereof, shall be continuing.

         The Company also covenants with each Holder of Securities of a series
issued to a Sierra Pacific Trust (i) to maintain directly or indirectly 100%
ownership of the Common Securities of such Sierra Pacific Trust; provided,
however, that any permitted successor of the Company hereunder may succeed to
the Company's ownership of such Common Securities, (ii) not to voluntarily
terminate, wind-up or liquidate such Sierra Pacific Trust, except (a) in
connection with a distribution of the Securities of such series to the holders
of Preferred Securities in liquidation of such Sierra Pacific Trust or (b) in
connection with certain mergers, consolidations or amalgamations permitted by
the related Trust Agreement and (iii) to use its reasonable efforts, consistent
with the terms and provisions of such Trust Agreement, to cause such Sierra
Pacific Trust to remain classified as a grantor trust and not an association
taxable as a corporation for United States federal income tax purposes.]

                            REDEMPTION OF SECURITIES

         Section 11.1      APPLICABILITY OF THIS ARTICLE.

         Redemption of Securities (whether by operation of a sinking fund or
otherwise) as permitted or required by any form of Security issued pursuant to
this Indenture shall be made in accordance with such form of Security and this
Article; provided, however, that if any provision of any such form of Security
shall conflict with any provision of this Article, the provision of such form of
Security shall govern. Except as otherwise set forth in the form of Security for
such series, each Security shall be subject to partial redemption only in the
amount of $25 or, in the case of the Securities of a series issued to a Sierra
Pacific Trust, $25, or integral multiples thereof.

         Section 11.2      ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Company of less than all of the Securities of any particular series and
having the same terms, the Company shall, not less than 30 nor more than 60 days
prior to the date fixed for redemption (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such date and of the
principal amount of Securities of that series to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities, the Company shall furnish
the Trustee with an Officers' Certificate and an Opinion of Counsel evidencing
compliance with such restriction.

         Section 11.3      SELECTION OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of a portion of the principal amount of any Security of such series,
provided that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.

                                       63

<PAGE>


         The Trustee shall promptly notify the Company in writing of the
Securities selected for partial redemption and 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 Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed. If the Company shall so direct, Securities registered in the name of
the Company, any Affiliate or any Subsidiary thereof shall not be included in
the Securities selected for redemption.

         Section 11.4      NOTICE OF REDEMPTION.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not later than the thirtieth day, and not earlier than the
sixtieth day, prior to the date fixed for redemption, to each Holder of
Securities to be redeemed, at the address of such Holder as it appears in the
Securities Register.

         With respect to Securities of each series to be redeemed, each notice
of redemption shall state:

                  (a) the date fixed for redemption for Securities of such
series;

                  (b) the redemption price at which Securities of such series
are to be redeemed;

                  (c) if less than all Outstanding Securities of such particular
series and having the same terms are to be redeemed, the identification (and, in
the case of partial redemption, the respective principal amounts) of the
particular Securities to be redeemed;

                  (d) that on the date fixed for redemption, the redemption
price at which such Securities are to be redeemed will become due and payable
upon each such Security or portion thereof, and that interest thereon, if any,
shall cease to accrue on and after said date;

                  (e) the place or places where such Securities are to be
surrendered for payment of the redemption price at which such Securities are to
be redeemed; and

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

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall not be
irrevocable. The notice if mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice. In any case, a failure to give such notice by mail or any
defect in the notice to the Holder of any Security designated for redemption as
a whole or in part shall not affect the validity of the proceedings for the
redemption of any other Security.

         Section 11.5      DEPOSIT OF REDEMPTION PRICE.

         Prior to 10:00 a.m. New York City time on the redemption date specified
in the notice of redemption given as provided in Section 11.4, the Company will
deposit with the Trustee or with one or more paying agents an amount of money
sufficient to redeem on the redemption date all the Securities so called for
redemption at the applicable redemption price.

         Section 11.6      PAYMENT OF SECURITIES CALLED FOR REDEMPTION.

         If any notice of redemption has been given as provided in Section 11.4,
the Securities or portion of Securities with respect to which such notice has
been given shall become due and payable on the date and at the place or places
stated in such notice at the applicable redemption price. On presentation and
surrender of such Securities at a place of payment in said notice specified, the
said securities or the specified portions thereof shall be paid and redeemed by
the Company at the applicable redemption price.

         Upon presentation of any Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and deliver to the Holder
thereof, at the expense of the Company, a new Security or Securities of the same
series, of authorized denominations, in aggregate principal amount equal to the
unredeemed portion of the Security so presented and having the same Original
Issue Date, Stated Maturity and terms. If a Global Security is so surrendered,
such new Security will also be a new Global Security.

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

         Section 11.7      COMPANY'S RIGHT OF REDEMPTION.

                  (a) Unless otherwise specified as contemplated by Section 3.1
with respect to the Securities of a particular series and notwithstanding any
additional redemption rights that may be so specified, the Company may, at its
option, redeem the Securities of any series after their date of issuance in
whole at any time or in part from time to time, subject to the provisions of
this clause (a) and the other provisions of this Article XI. Unless otherwise
specified as contemplated by Section 3.1 with respect to the Securities of a
particular series, the redemption price for any Security so redeemed pursuant to
this clause (a) shall be equal to 100% of the principal amount of such
Securities plus any accrued and unpaid interest, including any Additional
Interest, to the date fixed for redemption. The Company shall not redeem the
Securities in part unless all accrued and unpaid interest (including any
Additional Interest) has been paid in full on all Securities Outstanding for all
interest periods terminating on or prior to the date fixed for redemption.

                  (b) In the case of the Securities of a series issued to a
Sierra Pacific Trust, except as otherwise specified as contemplated by Section
3.1, if a Special Event in respect of such

                                       65

<PAGE>


Sierra Pacific Trust shall occur and be continuing, the Company may, at its
option, redeem the Securities of such series within 90 days of the occurrence of
such Special Event, in whole but not in part, subject to the provisions of this
clause (b) and the other provisions of this Article Eleven. The redemption price
for any Security so redeemed pursuant to this clause (b) shall be equal to 100%
of the principal amount of such Securities then Outstanding plus accrued and
unpaid interest, including any Additional Interest, to the date fixed for
redemption.

                                  ARTICLE XII.

                                  SINKING FUNDS

         Section 12.1      APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities.

         The minimum amount of any sinking fund payment provided for by the
terms of any Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any sinking fund payment in excess of such minimum
amount which is permitted to be made by the terms of such Securities of any
series is herein referred to as an "optional sinking fund payment". If provided
for by the terms of any Securities of any series, the cash amount of any sinking
fund payment may be subject to reduction as provided in Section 12.2. Each
sinking fund payment shall be applied to the redemption of Securities of any
series as provided for by the terms of such Securities.

         Section 12.2      SATISFACTION OF SINKING FUND PAYMENTS WITH
SECURITIES.

         In lieu of making all or any part of a mandatory sinking fund payment
with respect to any Securities of a series in cash, the Company may at its
option, at any time no more than 16 months and no less than 30 days prior to the
date on which such sinking fund payment is due, deliver to the Trustee
Securities of such series (together with the unmatured Coupons, if any,
appertaining thereto) theretofore purchased or otherwise acquired by the
Company, except Securities of such series that have been redeemed through the
application of mandatory or optional sinking fund payments pursuant to the terms
of the Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value; provided that the Securities to be so credited have not
been previously so credited. The Securities to be so credited shall be received
and credited for such purpose by the Trustee at the redemption price for such
Securities, as specified in the Securities so to be redeemed, for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

         Section 12.3      REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
such Securities pursuant to the terms of such Securities, the portion thereof,
if any, which is to be satisfied by payment of cash in the currency in which the
Securities of such series are payable (except as provided pursuant to Section
3.1) and the portion thereof, if any, which is to be satisfied by delivering and
crediting Securities pursuant to Section 12.2 and will also deliver to the
Trustee any Securities to be so delivered. Such Certificate shall be irrevocable
and upon its delivery the Company shall be obligated to make the cash payment or
payments therein referred to, if any, on or before the succeeding sinking fund
payment date. In the case of the failure of the Company to deliver such
Certificate (or, as required by this Indenture, the Securities and coupons, if
any, specified in such Certificate), the sinking fund payment due on the
succeeding sinking fund payment date for such series shall be paid entirely in
cash and shall be sufficient to redeem the principal amount of the Securities of
such series subject to a mandatory sinking fund payment without the right to
deliver or credit securities as provided in Section 12.2 and without the right
to make the optional sinking fund payment with respect to such series at such
time.

         Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Securities
of such series at the redemption price specified in such Securities with respect
to the sinking fund. Any sinking fund moneys not so applied or allocated by the
Trustee (or by the Company if the Company is acting as its own Paying Agent,
segregated and held in trust as provided in Section 10.3) for such series and
together with such payment (or such amount so segregated) shall be applied in
accordance with the provisions of this Section 12.3. Any and all sinking fund
moneys with respect to the Securities of any particular series held by the
Trustee (or if the Company is acting as its own Paying Agent, segregated and
held in trust as provided in Section 10.3) on the last sinking fund payment date
with respect to Securities of such series and not held for the payment or
redemption of particular Securities of such series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent),
together with other moneys, if necessary, to be deposited (or segregated)
sufficient for the purpose, to the payment of the principal of the Securities of
such series at Maturity. The Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 11.3 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 11.4. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Section 11.6. On or before each sinking fund
payment date, the Company shall pay to the Trustee (or, if the Company is acting
as its own Paying Agent, the Company shall segregate and hold in trust as
provided in Section 10.3) in cash a sum in the currency in which Securities of
such series are

                                       67

<PAGE>


payable (except as provided pursuant to Section 3.1) equal to the principal and
any interest accrued to the redemption date for Securities or portions thereof
to be redeemed on such sinking fund payment date pursuant to this Section 12.3.

         Neither the Trustee nor the Company shall redeem any Securities of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund for such series during the
continuance of a default in payment of interest, if any, on any Securities of
such series or of any Event of Default (other than an Event of Default occurring
as a consequence of this paragraph) with respect to the Securities of such
series, except that if the notice of redemption shall have been provided in
accordance with the provisions hereof, the Trustee (or the Company if the
Company is then acting as its own Paying Agent) shall redeem such Securities if
cash sufficient for that purpose shall be deposited with the Trustee (or
segregated by the Company) for that purpose in accordance with the terms of this
Article Twelve. Except as aforesaid, any moneys in the sinking fund for such
series at the time when any such default or Event of Default shall occur and any
moneys thereafter paid into such sinking fund shall, during the continuance of
such default or Event of Default, be held as security for the payment of the
Securities and coupons, if any, of such series; provided, however, that in case
such default or Event of Default shall have been cured or waived herein, such
moneys shall thereafter be applied on the next sinking fund payment date for the
Securities of such series on which such moneys may be applied pursuant to the
provisions of this Section 12.3.

                                  ARTICLE XIII.

                           SUBORDINATION OF SECURITIES

         Section 13.1      SECURITIES SUBORDINATE TO SENIOR DEBT.

         The Company covenants and agrees, and each Holder of a Security, by its
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article, the payment of the principal
of (and premium, if any) and interest (including any Additional Interest) on
each and all of the Securities are hereby expressly made subordinate and subject
in right of payment to the prior payment in full of all amounts then due and
payable in respect of all Senior Debt.

         Section 13.2      PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company (each such event, if any, herein
sometimes referred to as a "Proceeding"), then the holders of Senior Debt shall
be entitled to receive payment in full of principal of (and premium, if any) and
interest, if any, on such Senior Debt, or provision shall be made for such
payment in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of Senior Debt, before the Holders of the Securities are entitled to
receive or retain any payment or distribution of any kind or character, whether
in cash, property or securities (including any payment or

                                       68

<PAGE>


distribution which may be payable or deliverable by reason of the payment of any
other Debt of the Company (including any series of the Securities) subordinated
to the payment of the Securities, such payment or distribution being hereinafter
referred to as a "Junior Subordinated Payment"), on account of principal of (or
premium, if any) or interest (including any Additional Interest) on the
Securities or on account of the purchase or other acquisition of Securities by
the Company or any Subsidiary and to that end the holders of Senior Debt shall
be entitled to receive, for application to the payment thereof, any payment or
distribution of any kind or character, whether in cash, property or securities,
including any Junior Subordinated Payment, which may be payable or deliverable
in respect of the Securities in any such Proceeding.

         In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, including any Junior Subordinated
Payment, before all Senior Debt is paid in full or payment thereof is provided
for in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of Senior Debt, and if such fact shall, at or prior to the time of such
payment or distribution, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment or distribution shall be
paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making payment
or distribution of assets of the Company for application to the payment of all
Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in
full, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Debt.

         For purposes of this Article only, the words "any payment or
distribution of any kind or character, whether in cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment which securities are subordinated in
right of payment to all then outstanding Senior Debt to substantially the same
extent as the Securities are so subordinated as provided in this Article. The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the sale of
all or substantially all of its properties and assets as an entirety to another
Person or the liquidation or dissolution of the Company following the sale of
all or substantially all of its properties and assets as an entirety to another
Person upon the terms and conditions set forth in Article Eight shall not be
deemed a Proceeding for the purposes of this Section if the Person formed by
such consolidation or into which the Company is merged or the Person which
acquires by sale such properties and assets as an entirety, as the case may be,
shall, as a part of such consolidation, merger, or sale comply with the
conditions set forth in Article Eight.

         Section 13.3      PRIOR PAYMENT TO SENIOR DEBT UPON ACCELERATION OF
SECURITIES.

         In the event that any Securities are declared due and payable before
their Stated Maturity, then and in such event the holders of the Senior Debt
outstanding at the time such Securities so become due and payable shall be
entitled to receive payment in full of all amounts due on or in

                                       69

<PAGE>


respect of such Senior Debt (including any amounts due upon acceleration), or
provision shall be made for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Debt, before the
Holders of the Securities are entitled to receive any payment or distribution of
any kind or character, whether in cash, properties or securities (including any
Junior Subordinated Payment) by the Company on account of the principal of (or
premium, if any) or interest (including any Additional Interest) on the
Securities or on account of the purchase or other acquisition of Securities by
the Company or any Subsidiary; provided, however, that nothing in this Section
shall prevent the satisfaction of any sinking fund payment in accordance with
this Indenture or as otherwise specified as contemplated by Section 3.1 for the
Securities of any series by delivering and crediting pursuant to Section 12.2 or
as otherwise specified as contemplated by Section 3.1 for the Securities of any
series Securities which have been acquired (upon redemption or otherwise) prior
to such declaration of acceleration.

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

         The provisions of this Section shall not apply to any payment with
respect to which Section 13.2 would be applicable.

         Section 13.4      NO PAYMENT WHEN SENIOR DEBT IN DEFAULT.

                  (a) In the event and during the continuation of any default in
the payment of principal of (or premium, if any) or interest on any Senior Debt,
or in the event that any event of default with respect to any Senior Debt shall
have occurred and be continuing and shall have resulted in such Senior Debt
becoming or being declared due and payable prior to the date on which it would
otherwise have become due and payable, unless and until such event of default
shall have been cured or waived or shall have ceased to exist and such
acceleration shall have been rescinded or annulled, or (b) in the event any
judicial proceeding shall be pending with respect to any such default in payment
or such event or default, then no payment or distribution of any kind or
character, whether in cash, properties or securities (including any Junior
Subordinated Payment) shall be made by the Company on account of principal of
(or premium, if any) or interest (including any Additional Interest), if any, on
the Securities or on account of the purchase or other acquisition of Securities
by the Company or any Subsidiary; provided, however, that nothing in this
Section shall prevent the satisfaction of any sinking fund payment in accordance
with this Indenture or as otherwise specified as contemplated by Section 3.1 for
the Securities of any series by delivering and crediting pursuant to Section
12.2 or as otherwise specified as contemplated by Section 3.1 for the Securities
of any series Securities which have been acquired (upon redemption or otherwise)
prior to such default in payment or event of default.

<PAGE>


         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

         The provisions of this Section shall not apply to any payment with
respect to which Section 13.2 would be applicable.

         Section 13.5      PAYMENT PERMITTED IF NO DEFAULT.

         Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time except during
the pendency of any Proceeding referred to in Section 13.2 or under the
conditions described in Sections 13.3 and 13.4, from making payments at any time
of principal of (and premium, if any) or interest on the Securities, or (b) the
application by the Trustee of any money or Government Obligations deposited with
it hereunder to the payment of or on account of the principal of (and premium,
if any) or interest (including any Additional Interest) on the Securities or the
retention of such payment by the Holders, if, at the time of such application by
the Trustee, it did not have knowledge that such payment would have been
prohibited by the provisions of this Article.

         Section 13.6      SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR DEBT.

         Subject to the payment in full of all Senior Debt, or the provision for
such payment in cash or cash equivalents or otherwise in a manner satisfactory
to the holders of Senior Debt, the Holders of the Securities shall be subrogated
to the extent of the payments or distributions made to the holders of such
Senior Debt pursuant to the provisions of this Article (equally and ratably with
the holders of all indebtedness of the Company which by its express terms is
subordinated to Senior Debt of the Company to substantially the same extent as
the Securities are subordinated to the Senior Debt and is entitled to like
rights of subrogation by reason of any payments or distributions made to holders
of such Senior Debt) to the rights of the holders of such Senior Debt to receive
payments and distributions of cash, property and securities applicable to the
Senior Debt until the principal of (and premium, if any) and interest on the
Securities shall be paid in full. For purposes of such subrogation or
assignment, no payments or distributions to the holders of the Senior Debt of
any cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article, and no
payments over pursuant to the provisions of this Article to the holders of
Senior Debt by Holders of the Securities or the Trustee, shall, as among the
Company, its creditors other than holders of Senior Debt, and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Debt.

         Section 13.7      PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Debt on the other hand. Nothing contained in
this Article or elsewhere in this Indenture or in the Securities is intended to
or shall (a) impair, as between the Company and the Holders of the Securities,
the obligations of the Company, which are absolute and unconditional, to pay to
the Holders of the Securities the principal of (and premium, if any) and
interest (including any Additional Interest) on the Securities as and when the
same shall become due and payable in accordance with their terms; or (b) affect
the relative rights against the Company of the Holders of the Securities and
creditors of the Company other than their rights in relation to the holders of
Senior Debt; or (c) prevent the Trustee or the Holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture including, without limitation, filing and voting claims in any
Proceeding, subject to the rights, if any, under this Article of the holders of
Senior Debt to receive cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder.

         Section 13.8      TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each Holder of a Security by his or her acceptance thereof authorizes
and directs the Trustee on his or her behalf to take such action as may be
necessary or appropriate to acknowledge or effectuate the subordination provided
in this Article and appoints the Trustee his or her attorney-in-fact for any and
all such purposes.

         Section 13.9      NO WAIVER OF SUBORDINATION PROVISIONS.

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

         Section 13.10  NOTICE TO TRUSTEE.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Debt or from any trustee, agent or representative
therefor (whether or not the facts contained in such notice are true); provided,
however, that if the Trustee shall not have received the notice provided for in
this Section at least two Business Days prior to the date upon

                                       72

<PAGE>


which by the terms hereof any monies may become payable for any purpose
(including, without limitation, the payment of the principal of (and premium, if
any) or interest (including any Additional Interest) on any Security), then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such monies and to apply the same to
the purpose for which they were received and shall not be affected by any notice
to the contrary which may be received by it within two Business Days prior to
such date.

         Section 13.11  RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
AGENT.

         Upon any payment or distribution of assets of the Company referred to
in this Article, the Trustee, subject to the provisions of Article Six, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior Debt and
other indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.

         Section 13.12  TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR DEBT.

         The Trustee, in its capacity as trustee under this Indenture, shall not
be deemed to owe any fiduciary duty to the holders of Senior Debt and shall not
be liable to any such holders if it shall in good faith mistakenly pay over or
distribute to Holders of Securities or to the Company or to any other Person
cash, property or securities to which any holders of Senior Debt shall be
entitled by virtue of this Article or otherwise.

         Section 13.13  RIGHTS OF TRUSTEE AS HOLDER OF SENIOR DEBT; PRESERVATION
OF TRUSTEE'S RIGHTS.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Debt which may at
any time be held by it, to the same extent as any other holder of Senior Debt,
and nothing in this Indenture shall deprive the Trustee of any of its rights as
such holder.

         Section 13.14  ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within

Guarantee Agreement to any Person except a Holder exercising his or her rights
pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on acceptance by

         (b) If an Event of Default has occurred and is continuing, the
Guarantee Trustee shall enforce this Guarantee Agreement for the benefit of the
Holders.

         (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

                  (i) prior to the occurrence of any Event of Default and after
         the curing or waiving of all such Events of Default that may have
         occurred:

                           (A) the duties and obligations of the Guarantee
                  Trustee shall be determined solely by the express provisions
                  of this Guarantee Agreement, and the Guarantee Trustee shall
                  not be liable except for the performance of such duties and
                  obligations as are specifically set forth in this Guarantee

                  Guarantee Trustee, the Guarantee Trustee may conclusively
                  rely, as to the truth of the statements and the correctness of
                  the opinions expressed therein, upon any certificates or
                  opinions furnished to the Guarantee Trustee and conforming to
                  the requirements of this Guarantee Agreement; but in the case
                  of any such certificates or opinions that by any provision
                  hereof or of the Trust Indenture Act are specifically required
                  to be furnished to the Guarantee Trustee, the Guarantee
                  Trustee shall be under a duty to examine the same to determine

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

                  (iii) the Guarantee Trustee shall not be liable with respect
         to any action taken or omitted to be taken by it in good faith in
         accordance with the direction of the Holders

         the Guarantee Trustee to expend or risk its own funds or otherwise
         incur personal financial liability in the performance of any of its

         Guarantee Trustee shall have reasonable grounds for believing that the
         repayment of such funds or liability is not reasonably assured to it
         under the terms of this Guarantee Agreement or adequate indemnity
         against such risk or liability is not reasonably assured to it.

         Section 3.2.      Certain Rights of Guarantee Trustee.

         (a)      Subject to the provisions of Section 3.1:

                  (i) The Guarantee Trustee may rely and shall be fully
         protected in acting or refraining from acting upon any resolution,

         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document reasonably believed by it to be
         genuine and to have been signed, sent or presented by the proper party
         or parties.

                  (ii) Any direction or act of the Guarantor contemplated by

         Agreement, the Guarantee Trustee shall deem it desirable that a matter
         be proved or established before taking, suffering or omitting to take
         any action hereunder, the Guarantee Trustee (unless other evidence is
         herein specifically prescribed) may, in the absence of bad faith on its
         part, request and rely upon an Officers' Certificate which, upon
         receipt of such request from the Guarantee Trustee, shall be promptly
         delivered by the Guarantor.

                  (iv) The Guarantee Trustee may consult with legal counsel, and
         the written advice or opinion of such legal counsel with respect to

                  (v) The Guarantee Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such Holder
         shall have provided to the Guarantee Trustee such adequate security and
         indemnity as would satisfy a reasonable person in the position of the
         Guarantee Trustee, against the costs, expenses (including attorneys'
         fees and expenses) and liabilities that might be incurred by it in
         complying with such request or direction, including such reasonable
         advances as may be requested by the Guarantee Trustee; provided that,
         nothing contained in this Section 3.2(a)(v) shall be taken to relieve
         the Guarantee Trustee, upon the occurrence of an Event of Default, of
         its obligation to exercise the rights and powers vested in it by this
         Guarantee Agreement.

                  (vi) The Guarantee Trustee shall not be bound to make any

         powers hereunder or perform any duties hereunder either directly or by
         or through its agents or attorneys, and the Guarantee Trustee shall not
         be responsible for any misconduct or negligence on the part of any such
         agent or attorney appointed with due care by it hereunder.

                  (viii) Whenever in the administration of this Guarantee
         Agreement the Guarantee Trustee shall deem it desirable to receive

         any other action hereunder, the Guarantee Trustee (A) may request
         instructions from the Holders, (B) may refrain from enforcing such
         remedy or right or taking such other action until such instructions are
         received, and (C) shall be protected in acting in accordance with such
         instructions.

         (b) No provision of this Guarantee Agreement shall be deemed to impose
any duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee

hold it harmless against, any loss, liability or expense incurred without

         corporation publishes reports of condition at least annually, pursuant
         to law or to the requirements of the supervising or examining
         authority, then, for the purposes of this Section and to the extent
         permitted by the Trust Indenture Act, the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

         (b) If at any time the Guarantee Trustee shall cease to be eligible to

         (b) The Guarantee Trustee shall not be removed until a Successor
Guarantee Trustee has been appointed and has accepted such appointment by
written instrument executed by such Successor Guarantee Trustee and delivered to
the Guarantor.

         (c) The Guarantee Trustee appointed hereunder shall hold office until a
Successor Guarantee Trustee shall have been appointed or until its removal or
resignation. The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the
Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has

                                       10

accepted such appointment by instrument in writing executed by such Successor

Guarantee Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for appointment of a Successor Guarantee Trustee. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Guarantee Trustee.

Securities;

         (f)      the settlement or compromise of any obligation guaranteed

first instituting a legal proceeding against the Guarantee Trustee, the Issuer
or any other Person.

against the Issuer in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement and shall have the right to waive

hereunder to make Guarantee Payments pursuant to the terms of this Guarantee
Agreement notwithstanding the occurrence of any event referred to in subsections

Securities, (ii) the distribution of Debentures to the Holders in exchange for
all of the Preferred Securities or (iii) full payment of the amounts payable in

Guarantee Agreement to any Person except a Holder exercising his or her rights
pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on acceptance by

effective whether or not conveyancing documents have been executed and delivered

         (b) If an Event of Default has occurred and is continuing, the
Guarantee Trustee shall enforce this Guarantee Agreement for the benefit of the
Holders.

         (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

                  (i) prior to the occurrence of any Event of Default and after
         the curing or waiving of all such Events of Default that may have
         occurred:

                           (A) the duties and obligations of the Guarantee
                  Trustee shall be determined solely by the express provisions
                  of this Guarantee Agreement, and the Guarantee Trustee shall
                  not be liable except for the performance of such duties and
                  obligations as are specifically set forth in this Guarantee
                  Agreement; and

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

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

         Guarantee Trustee shall have reasonable grounds for believing that the
         repayment of such funds or liability is not reasonably assured to it
         under the terms of this Guarantee Agreement or adequate indemnity
         against such risk or liability is not reasonably assured to it.

         Section 3.2.      Certain Rights of Guarantee Trustee.

         (a)      Subject to the provisions of Section 3.1:

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

                  (ii) Any direction or act of the Guarantor contemplated by
         this Guarantee Agreement shall be sufficiently evidenced by an
         Officer's Certificate unless otherwise prescribed herein.

                  (iii) Whenever, in the administration of this Guarantee
         Agreement, the Guarantee Trustee shall deem it desirable that a matter
         be proved or established before taking, suffering or omitting to take
         any action hereunder, the Guarantee Trustee (unless other evidence is
         herein specifically prescribed) may, in the absence of bad faith on its
         part, request and rely upon an Officers' Certificate which, upon
         receipt of such request from the Guarantee Trustee, shall be promptly
         delivered by the Guarantor.

                  (iv) The Guarantee Trustee may consult with legal counsel, and

         hereunder in good faith and in accordance with such advice or opinion.
         Such legal counsel may be legal counsel to the Guarantor or any of its
         Affiliates and may be one of its employees. The Guarantee Trustee shall

                  (v) The Guarantee Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such Holder
         shall have provided to the Guarantee Trustee such adequate security and
         indemnity as would satisfy a reasonable person in the position of the
         Guarantee Trustee, against the costs, expenses (including attorneys'
         fees and expenses) and liabilities that might be incurred by it in
         complying with such request or direction, including such reasonable
         advances as may be requested by the Guarantee Trustee; provided that,
         nothing contained in this Section 3.2(a)(v) shall be taken to relieve
         the Guarantee Trustee, upon the occurrence of an Event of Default, of
         its obligation to exercise the rights and powers vested in it by this
         Guarantee Agreement.

                  (vi) The Guarantee Trustee shall not be bound to make any

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

                  (viii) Whenever in the administration of this Guarantee
         Agreement the Guarantee Trustee shall deem it desirable to receive
         instructions with respect to enforcing any remedy or right or taking
         any other action hereunder, the Guarantee Trustee (A) may request
         instructions from the Holders, (B) may refrain from enforcing such
         remedy or right or taking such other action until such instructions are
         received, and (C) shall be protected in acting in accordance with such
         instructions.

         (b) No provision of this Guarantee Agreement shall be deemed to impose
any duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

         The Guarantor agrees to indemnify the Guarantee Trustee for, and to
hold it harmless against, any loss, liability or expense incurred without

         Section 4.1.      Guarantee Trustee: Eligibility.

         (a)      There shall at all times be a Guarantee Trustee which shall:

         at least $50,000,000, and shall be a corporation meeting the
         requirements of Section 310(c) of the Trust Indenture Act. If such
         corporation publishes reports of condition at least annually, pursuant
         to law or to the requirements of the supervising or examining
         authority, then, for the purposes of this Section and to the extent
         permitted by the Trust Indenture Act, the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

         (b) If at any time the Guarantee Trustee shall cease to be eligible to
so act under Section 4.1(a), the Guarantee Trustee shall immediately resign in
the manner and with the effect set out in Section 4.2(c).

         (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 310(b) of the Trust Indenture Act, the
Guarantee Trustee and Guarantor shall in all respects comply with the provisions
of Section 310(b) of the Trust Indenture Act.

         Section 4.2.      Appointment, Removal and Resignation of the Guarantee
Trustee.

         (a) Subject to Section 4.2(b), the Guarantee Trustee may be appointed
or removed without cause at any time by the Guarantor.

         (b) The Guarantee Trustee shall not be removed until a Successor
Guarantee Trustee has been appointed and has accepted such appointment by
written instrument executed by such Successor Guarantee Trustee and delivered to
the Guarantor.

         (c) The Guarantee Trustee appointed hereunder shall hold office until a
Successor Guarantee Trustee shall have been appointed or until its removal or
resignation. The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the
Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has

                                       10

<PAGE>


accepted such appointment by instrument in writing executed by such Successor
Guarantee trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

         (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of resignation, the resigning
Guarantee Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for appointment of a Successor Guarantee Trustee. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Guarantee Trustee.

the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by or on behalf of the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim which the Issuer may have or assert. The

the Issuer to pay such amounts to the Holders.

         Section 5.2.      Waiver of Notice and Demand.

         The Guarantor hereby waives notice of acceptance of the Guarantee

Securities;

         (f)      the settlement or compromise of any obligation guaranteed

Agreement; and (iv) any Holder may institute a legal proceeding directly against

first instituting a legal proceeding against the Guarantee Trustee, the Issuer
or any other Person.

         Section 5.5.      Guarantee of Payment.

         This Guarantee Agreement creates a guarantee of payment and not of

         The Guarantor shall be subrogated to all (if any) rights of the Holders
against the Issuer in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement and shall have the right to waive
payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of

over such amount to the Holders.

         Section 5.7.      Independent Obligations.

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Preferred
Securities and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Guarantee
Agreement notwithstanding the occurrence of any event referred to in subsections
(a) through (g), inclusive, of Section 5.3 hereof.

effect upon (i) full payment of the Redemption Price of all Preferred
Securities, (ii) the distribution of Debentures to the Holders in exchange for
all of the Preferred Securities or (iii) full payment of the amounts payable in

                                 TRUST AGREEMENT
                                       OF
                    SIERRA PACIFIC RESOURCES CAPITAL TRUST I

         THIS TRUST AGREEMENT is made as of June 7, 1999 (this "Trust
Agreement"), by and among Sierra Pacific Resources, a Nevada corporation, as
Depositor (the "Depositor"), and The Bank of New York (Delaware), a Delaware
banking corporation, as trustee, and Richard K. Atkinson, as trustee (jointly,
the "Trustees"). The Depositor and the Trustees hereby agree as follows:

         1. The trust created hereby shall be known as "Sierra Pacific Resources
Capital Trust I" (the "Trust"), in which name the Trustees or the Depositor, to
the extent provided herein, may conduct the business of the Trust, make and
execute contracts, and sue and be sued.

         2. The Depositor hereby assigns, transfers, conveys and sets over to
the Trust the sum of $10. Such amount shall constitute the initial trust estate.
It is the intention of the parties hereto that the Trust created hereby
constitute a business trust under Chapter 38 of Title 12 of the Delaware Code,
12 DEL. C. ss. 3801, eT Seq. (the "Business Trust Act"), and that this document
constitute the governing instrument of the Trust. The Trustees are hereby
authorized and directed to execute and file a certificate of trust with the
Delaware Secretary of State in such form as the Trustees may approve.

         3. The Depositor and the Trustees will enter into an amended and
restated Trust Agreement satisfactory to each such party to provide for the
contemplated operation of the Trust created hereby and the issuance of the
Preferred Securities and Common Securities referred to therein. Prior to the
execution and delivery of such amended and restated Trust Agreement, the
Trustees shall not have any duty or obligation hereunder or with respect of the
trust estate, except as otherwise required by applicable law or as may be
necessary to obtain prior to such execution and delivery any licenses, consents
or approvals required by applicable law or otherwise. Notwithstanding the
foregoing, the Trustees may take all actions deemed proper as are necessary to
effect the transactions contemplated herein.

         4. The Depositor, as sponsor of the Trust, is hereby authorized, in its
discretion, (i) to prepare and file with the Securities and Exchange Commission
(the "Commission") and to execute, in the case of the 1933 Act Registration
Statement and 1934 Act Registration Statement (as herein defined), on behalf of
the Trust, (a) a Registration Statement (the "1933 Act Registration Statement"),
including all pre-effective and post-effective amendments thereto, relating to
the registration under the Securities Act of 1933, as amended (the "1933 Act"),
of the Preferred Securities of the Trust, (b) any preliminary prospectus or
prospectus or supplement thereto relating to the Preferred Securities of the
Trust required to be filed pursuant to the 1933 Act, and (c) a Registration
Statement on Form 8-A or other appropriate form (the "1934 Act Registration
Statement"), including all pre-effective and post-effective amendments thereto,
relating to the registration of the Preferred Securities of the Trust under the
Securities Exchange Act of 1934, as amended; (ii) if and at such time as
determined by the Depositor, to file with the New York Stock Exchange or other
exchange, or the National Association of Securities Dealers ("NASD"), and
execute on behalf of the Trust a listing application and all other applications,

<PAGE>


statements, certificates, agreements and other instruments as shall be necessary
or desirable to cause the Preferred Securities of the Trust to be listed on the
New York Stock Exchange or such other exchange, or the NASD's Nasdaq National
Market; (iii) to file and execute on behalf of the Trust, such applications,
reports, surety bonds, irrevocable consents, appointments of attorney for
service of process and other papers and documents that shall be necessary or
desirable to register the Preferred Securities of the Trust under the securities
or "Blue Sky" laws of such jurisdictions as the Depositor, on behalf of the
Trust, may deem necessary or desirable; (iv) to execute and deliver letters or
documents to, or instruments for filing with, a depository relating to the
Preferred Securities of the Trust; and (v) to execute, deliver and perform on
behalf of the Trust an underwriting agreement with one or more underwriters
relating to the offering of the Preferred Securities of the Trust.

         In the event that any filing referred to in this Section 4 is required
by the rules and regulations of the Commission, the New York Stock Exchange or
other exchange, NASD, or state securities or "Blue Sky" laws to be executed on
behalf of the Trust by the Trustees, the Trustees, in their capacity as trustees
of the Trust, are hereby authorized to join in any such filing and to execute on
behalf of the Trust any and all of the foregoing, it being understood that the
Trustees, in their capacity as trustees of the Trust, shall not be required to
join in any such filing or execute on behalf of the Trust any such document
unless required by the rules and regulations of the Commission, the New York
Stock Exchange or other exchange, NASD, or state securities or "Blue Sky" laws.

         5. This Trust Agreement may be executed in one or more counterparts.

         6. The number of trustees of the Trust initially shall be two and
thereafter the number of trustees of the Trust shall be such number as shall be
fixed from time to time by a written instrument signed by the Depositor which
may increase or decrease the number of trustees of the Trust; provided, however,
that to the extent required by the Business Trust Act, one trustee of the Trust
shall either be a natural person who is a resident of the State of Delaware or,
if not a natural person, an entity which has its principal place of business in
the State of Delaware. Subject to the foregoing, the Depositor is entitled to
appoint or remove without cause any trustee of the Trust at any time. Any
trustee of the Trust may resign upon thirty days' prior notice to the Depositor.

         7. The Depositor hereby agrees to (i) reimburse the Trustees for all
reasonable expenses (including reasonable fees and expenses of counsel and other
experts) and (ii) indemnify, defend and hold harmless the Trustees and any of
the officers, directors, employees and agents of the Trustees (the "Indemnified
Persons") from and against and all losses, damages, liabilities, claims,
actions, suits, costs, expenses, disbursements (including the reasonable fees
and expenses of counsel), taxes and penalties of any kind and nature whatsoever
(collectively, "Expenses"), to the extent that such Expenses arise out of or are
imposed upon or asserted at any time against such Indemnified Persons with
respect to the performance of this Trust Agreement, the creation, operation or
termination of the Trust or the transactions contemplated hereby; provided,
however, that the Depositor shall not be required to indemnify any Indemnified
Person

                                       -2-

<PAGE>


for any Expenses which are a result of the willful misconduct, bad faith or
gross negligence of such Indemnified Person.

         8. This Trust Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware (without regard to conflict
of laws principles).

         IN WITNESS WHEREOF, the parties hereto have caused this Trust Agreement
to be duly executed as of the day and year first above written.

Property Account for the payment of such Redemption Price.

                  (d) If the Property Trustee gives a notice of redemption in
respect of any Preferred Securities, then, by 12:00 noon, New York City time, on
the Redemption Date, [subject to Section 4.2(c),] the Property Trustee will, so
long as the Preferred Securities are in book-entry-only form, irrevocably
deposit with the Clearing Agency for the Preferred Securities funds sufficient
to pay the applicable Redemption Price and will give such Clearing Agency
irrevocable instructions and authority to pay the Redemption Price to the
Holders thereof. If the Preferred Securities are no longer in book-entry-only
form, the Property Trustee, [subject to Section

                                       17

<PAGE>


4.2(c),] will irrevocably deposit with the Paying Agent funds sufficient to pay
the applicable Redemption Price and will give the Paying Agent irrevocable
instructions and authority to pay the Redemption Price to the Holders thereof
upon surrender of their Preferred Securities Certificates. Notwithstanding the
foregoing, Distributions payable on or prior to the Redemption Date for any
Trust Securities called for redemption shall be payable to the Holders of such
Trust Securities as they appear on the Register for the Trust Securities on the
relevant record dates for the related Distribution Dates. If notice of
redemption shall have been given and funds deposited as required, then upon the
date of such deposit, all rights of Securityholders holding Trust Securities so
called for redemption will cease, except the right of such Securityholders to
receive the Redemption Price and any Distribution payable on or prior to the
Redemption Date, but without interest, and such Securities will cease to be
outstanding. In the event that any date on which any Redemption Price is payable
is not a Business Day, then payment of the Redemption Price payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay), except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day, in each case, with the same force and effect
as if made on such date. In the event that payment of the Redemption Price in
respect of any Trust Securities called for redemption is improperly withheld or
refused and not paid either by the Trust or by the Depositor pursuant to the
Guarantee, Distributions on such Trust Securities will continue to accrue, at
the then applicable rate, from the Redemption Date originally established by the
Trust for such Trust Securities to the date such Redemption Price is actually
paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.

                  (e) Payment of the Redemption Price on the Trust Securities
shall be made to the record holders thereof as they appear on the Securities
Register for the Trust Securities on the relevant record date, which shall be
one Business Day prior to the relevant Redemption Date; provided, however, that
in the event that the Preferred Securities do not remain in book-entry-only
form, the relevant record date shall be the date fifteen days prior to the
relevant Redemption Date.

                  (f) If, at any time, a Trust Special Event shall occur and be
continuing, the Administrative Trustees shall, unless the Debentures are
redeemed in the limited circumstances described below, within 90 days following
the occurrence of such Trust Special Event elect to either (i) dissolve the
Trust upon not less than 30 nor more than 60 days notice with the result that,
after satisfaction of creditors, if any, of the Trust, Debentures would be
distributed on a Pro Rata basis to the Holders of the Trust Preferred Securities
and the Trust Common Securities in liquidation of such Holders' interests in the
Trust; provided, however, that if at the time there is available to the Trust
the opportunity to eliminate, within such 90-day period, the Trust Special Event
by taking some ministerial action, such as filing a form or making an election,
or pursuing some other similar reasonable measure which in the sole judgment of
the Depositor has or will cause no adverse effect on the Trust, the Sponsor or
the Holders of the Trust Securities and will involve no material cost, the Trust
will pursue such measure in lieu of dissolution or (ii) cause the Preferred
Securities to remain outstanding; provided, that in the case of this clause
(ii), the Sponsor shall pay any and all expenses incurred by or payable by the
Trust attributable to the Trust Special Event. Furthermore, if in the case of
the occurrence of a Tax Event, the Administrative Trustees have received a Trust

                                       18

<PAGE>


Redemption Tax Opinion, then the Debenture Trustee shall have the right, within
90 days following the occurrence of such Tax Event, to elect to redeem the
Debentures in whole (but not in part) for cash upon not less than 30 nor more
than 60 days notice and promptly following such redemption, the Trust Securities
will be redeemed by the Trust at the Redemption Price as described in this
Section 4.2 below.

                  (g) If the Debentures are distributed to the Holders of the
Preferred Securities, the Depositor will use its best efforts to cause the
Debentures to be listed on the New York Stock Exchange or on such other national
securities exchange or similar organization as the Preferred Securities are then
listed or quoted.

                  (h) On the date fixed for any distribution of Debentures, upon
dissolution of the Trust, (i) the Preferred Securities and the Common Securities
will no longer be deemed to be outstanding and (ii) certificates representing
Trust Securities will be deemed to represent the Debentures having a liquidation
preference equal to the stated liquidation amount of such Trust Securities until
such certificates are presented to the Depositor or its agent for transfer or
reissuance.

                  (i) Subject to Section 4.3(a), if less than all the
Outstanding Trust Securities are to be redeemed on a Redemption Date, then the
aggregate Liquidation Amount of Trust Securities to be redeemed shall be
allocated on a pro rata basis (based on Liquidation Amounts) among the Common
Securities and the Preferred Securities. The particular Preferred Securities to
be redeemed shall be selected on a pro rata basis (based upon Liquidation
Amounts) not more than 60 days prior to the Redemption Date by the Property
Trustee from the Outstanding Preferred Securities not previously called for
redemption, by such method (including, without limitation, by lot) as the
Property Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to $25 or an integral multiple of
$25 in excess thereof) of the Liquidation Amount of Preferred Securities of a
denomination larger than $25. The Property Trustee shall promptly notify the
Security Registrar in writing of the Preferred Securities selected for
redemption and in the case of any Preferred Securities selected for partial
redemption, the Liquidation Amount thereof to be redeemed. For all purposes of
this Trust Agreement, unless the context otherwise requires, all provisions
relating to the redemption of Preferred Securities shall relate, in the case of
any Preferred Securities redeemed or to be redeemed only in part, to the portion
of the Liquidation Amount of Preferred Securities that has been or is to be
redeemed. [In any case, a failure to give such notice by mail or any defect in
the notice to the Holder of any Trust Security designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the
redemption of any other Trust Security.

         Section 4.3       SUBORDINATION OF COMMON SECURITIES.

                  (a) Payment of Distributions (including Additional Amounts, if
applicable) on, and the Redemption Price of, the Trust Securities, as
applicable, shall be made, subject to Section 4.2(i), pro rata among the Common
Securities and the Preferred Securities based on the Liquidation Amount of the
Trust Securities; provided, however, that if on any Distribution Date or
Redemption Date any Event of Default resulting from a Debenture Event of Default
shall have occurred and be

                                       19

<PAGE>


continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all
Outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all Outstanding Preferred Securities, shall have
been made or provided for and all funds immediately available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

                  (b) In the case of the occurrence of any Event of Default
resulting from any Debenture Event of Default, the Holder of Common Securities
will be deemed to have waived any right to act with respect to any such Event of
Default under this Trust Agreement until the effect of all such Events of
Default with respect to the Preferred Securities have been cured, waived or
otherwise eliminated. Until any such Event of Default under this Trust Agreement
with respect to the Preferred Securities has been so cured, waived or otherwise
eliminated, the Property Trustee shall act solely on behalf of the Holders of
the Preferred Securities and not the Holder of the Common Securities, and only
the Holders of the Preferred Securities will have the right to direct the
Property Trustee to act on their behalf.

         Section 4.4       PAYMENT PROCEDURES.

         Payments of Distributions (including Additional Amounts, if applicable)
in respect of the Preferred Securities shall be made by check mailed to the
address of the Person entitled thereto as such address shall appear on the
Securities Register or, if the Preferred Securities are held by a Clearing
Agency, such Distributions shall be made to the Clearing Agency in immediately
available funds, which shall credit the relevant Persons' accounts at such
Clearing Agency on the applicable distribution dates. Payments in respect of the
Common Securities shall be made in such manner as shall be mutually agreed
between the Property Trustee and the Common Securityholder.

         Section 4.5       TAX RETURNS AND REPORTS.

         The Administrative Trustees shall prepare (or cause to be prepared), at
the Depositor's expense, and file all United States Federal, state and local tax
and information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrative Trustees shall (a) prepare and file
(or cause to be prepared and filed) the appropriate Internal Revenue Service
Form required to be filed in respect of the Trust in each taxable year of the
Trust and (b) prepare and furnish (or cause to be prepared and furnished) to
each Securityholder the appropriate Internal Revenue Service form required to be
provided on such form. The Administrative Trustees shall provide the Depositor
and the Property Trustee with a copy of all such returns and reports promptly
after such filing or furnishing. The Trustees shall comply with United States
Federal withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Securityholders under the Trust
Securities.

         Section 4.6 PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST. Upon receipt
under the Debentures of Additional Sums, the Property Trustee shall promptly pay
any taxes, duties or governmental charges of whatsoever nature (other than
withholding taxes) imposed on the Trust by the United States or any other taxing
authority.

         Section 4.7       PAYMENTS UNDER INDENTURE.

         Any amount payable hereunder to any Holder of Preferred Securities
shall be reduced by the amount of any corresponding payment such Holder (and
Owner) has directly received pursuant to Section 5.8 of the Indenture.

                                   Article V.

                          TRUST SECURITIES CERTIFICATES

         Section 5.1       INITIAL OWNERSHIP.

         Upon the creation of the Trust and the contribution by the Depositor
pursuant to Section 2.3 and until the issuance of the Trust Securities, and at
any time during which no Trust Securities are outstanding, the Depositor shall
be the sole beneficial owner of the Trust.

         Section 5.2       THE TRUST SECURITIES CERTIFICATES.

         The Preferred Securities Certificates shall be issued in minimum
denominations of $25 Liquidation Amount and integral multiples of $25 in excess
thereof, and the Common Securities Certificates shall be issued in denominations
of $25 Liquidation Amount and integral multiples thereof. The Trust Securities
Certificates shall be executed on behalf of the Trust by manual signature of at
least one Administrative Trustee. Trust Securities Certificates bearing the
manual signatures of individuals who were, at the time when such signatures
shall have been affixed, authorized to sign on behalf of the Trust, shall be
validly issued and entitled to the benefits of this Trust Agreement,
notwithstanding that such individuals or any of them shall have ceased to be so
authorized prior to the delivery of such Trust Securities Certificates or did
not hold such offices at the date of delivery of such Trust Securities
Certificates. A transferee of a Trust Securities Certificate shall become a
Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 5.4, 5.11
and 5.13.

         Section 5.3       EXECUTION AND DELIVERY OF TRUST SECURITIES
CERTIFICATES.

         At each Time of Delivery, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in

upon the written order of the Depositor, signed by its chairman of the board,
its president, any executive vice president or any vice president, treasurer or

                                       21

assistant treasurer or controller without further corporate action by the
Depositor, in authorized denominations.

         Section 5.4       REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED
SECURITIES CERTIFICATES.

         The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of
Preferred Securities Certificates (the "Securities Register") in which, the
registrar designated by the Depositor (the "Securities Registrar"), subject to
such reasonable regulations as it may prescribe, shall provide for the
registration of Preferred Securities Certificates and Common Securities
Certificates (subject to Section 5.10 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Preferred
Securities Certificates as herein provided. The Bank shall be the initial
Securities Registrar. Upon surrender for registration of transfer of any
Preferred Securities Certificate at the office or agency maintained pursuant to
Section 5.8, the Administrative Trustees or any one of them shall execute and
deliver, in the name of the designated transferee or transferees, one or more
new Preferred Securities Certificates in authorized denominations of a like
aggregate Liquidation Amount dated the date of execution by such Administrative
Trustee or Trustees. The Securities Registrar shall not be required to register
the transfer of any Preferred Securities that have been called for redemption.
At the option of a Holder, Preferred Securities Certificates may be exchanged
for other Preferred Securities Certificates in authorized denominations of the
same class and of a like aggregate Liquidation Amount upon surrender of the
Preferred Securities Certificates to be exchanged at the office or agency
maintained pursuant to Section 5.8. Every Preferred Securities Certificate
presented or surrendered for registration of transfer or exchange shall be
accompanied by a written instrument of transfer in form satisfactory to an
Administrative Trustee and the Securities Registrar duly executed by the Holder
or his attorney duly authorized in writing. Each Preferred Securities
Certificate surrendered for registration of transfer or exchange shall be
cancelled and subsequently disposed of by an Administrative Trustee in
accordance with such Person's customary practice. No service charge shall be
made for any registration of transfer or exchange of Preferred Securities
Certificates, but the Securities Registrar may require payment of a sum
sufficient to cover any tax or governmental charge that maybe imposed in
connection with any transfer or exchange of Preferred Securities Certificates.

         Section 5.5       MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
CERTIFICATES.

         If (a) any mutilated Trust Securities Certificate shall be surrendered
to the Securities Registrar, or if the Securities Registrar shall receive
evidence to its satisfaction of the destruction, loss or theft of any Trust
Securities Certificate and (b) there shall be delivered to the Securities
Registrar and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees, or any one of them, on behalf of the
Trust shall execute and make available for delivery, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a
new Trust Securities Certificate of like class, tenor and denomination. In
connection with the issuance of any new Trust

                                       22

<PAGE>


Securities Certificate under this Section, the Administrative Trustees or the
Securities Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection therewith.
Any duplicate Trust Securities Certificate issued pursuant to this Section shall
constitute conclusive evidence of an undivided beneficial interest in the assets
of the Trust, as if originally issued, whether or not the lost, stolen or
destroyed Trust Securities Certificate shall be found at any time.

         Section 5.6       PERSONS DEEMED SECURITYHOLDERS.

         The Administrative Trustees or the Securities Registrar shall treat the
Person in whose name any Trust Securities Certificate shall be registered in the
Securities Register as the owner of such Trust Securities Certificate for the
purpose of receiving distributions and for all other purposes whatsoever, and
neither the Trustees nor the Securities Registrar shall be bound by any notice
to the contrary.

         Section 5.7       ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND
ADDRESSES.

         Each Holder of a Trust Securities Certificate, and each Owner shall be
deemed to have agreed not to hold the Depositor, the Property Trustee or the
Administrative Trustees accountable by reason of the disclosure of its name and
address, regardless of the source from which such information was derived.

         Section 5.8       MAINTENANCE OF OFFICE OR AGENCY.

         The Administrative Trustees shall maintain an office or offices or
agency or agencies where Preferred Securities Certificates may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Trustees in respect of the Trust Securities Certificates may be served.
The Administrative Trustees initially designate Sierra Pacific Resources, P.O.
Box 30150 (6100 Neil Road), Reno, Nevada 89520-3150, Attn: __________, as its
principal corporate trust office for such purposes. The Administrative Trustees
shall give prompt written notice to the Depositor and to the Securityholders of
any change in the location of the Securities Register or any such office or
agency.

         Section 5.9       APPOINTMENT OF PAYING AGENT.

         The Paying Agent shall make distributions to Securityholders from the
Property Account and shall report the amounts of such distributions to the
Property Trustee and the Administrative Trustees. Any Paying Agent shall have
the revocable power to withdraw funds from the Property Account for the purpose
of making the distributions referred to above. The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust Agreement in any material respect. The Paying Agent
shall initially be the Bank, and any co-paying agent chosen by the Bank, and
acceptable to the Administrative Trustees and the Depositor. Any Person acting
as Paying Agent shall be permitted to resign as Paying Agent upon 30 days'
written

                                       23

<PAGE>


notice to the Administrative Trustees, the Property Trustee and the Depositor.
In the event that the Bank shall no longer be the Paying Agent or a successor
Paying Agent shall resign or its authority to act be revoked, the Administrative
Trustees shall appoint a successor that is acceptable to the Property Trustee
and the Depositor to act as Paying Agent (which shall be a bank or trust
company). The Administrative Trustees shall cause such successor Paying Agent or
any additional Paying Agent appointed by the Administrative Trustees to execute
and deliver to the Trustees an instrument in which such successor Paying Agent
or additional Paying Agent shall agree with the Trustees that as Paying Agent,
such successor Paying Agent or additional Paying Agent will hold all sums, if
any, held by it for payment to the Securityholders in trust for the benefit of
the Securityholders entitled thereto until such sums shall be paid to such
Securityholders. The Paying Agent shall return all unclaimed funds to the
Property Trustee and upon removal of a Paying Agent such Paying Agent shall also
return all funds in its possession to the Property Trustee. The provisions of
Sections 8.1, 8.3 and 8.6 herein shall apply to the Bank also in its role as
Paying Agent, for so long as the Bank shall act as Paying Agent and, to the
extent applicable, to any other paying agent appointed hereunder. Any reference
in this Agreement to the Paying Agent shall include any co-paying agent unless
the context requires otherwise.

         Section 5.10      OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

         At each Time of Delivery, the Depositor shall acquire and retain
beneficial and record ownership of the Common Securities. To the fullest extent
permitted by law, other than a transfer in connection with a transaction
permitted by Section 8.1 of the Indenture, any attempted transfer of the Common
Securities shall be void. The Administrative Trustees shall cause each Common
Securities Certificate issued to the Depositor to contain a legend stating "THIS
CERTIFICATE IS NOT TRANSFERABLE OTHER THAN IN ACCORDANCE WITH THE TRUST
AGREEMENT (DEFINED BELOW)".

         Section 5.11      BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON
SECURITIES CERTIFICATE.

                  (a) The Preferred Securities Certificates, upon original
issuance, will be issued in the form of a typewritten Preferred Securities
Certificate or Certificates representing Book-Entry Preferred Securities
Certificates, to be delivered to The Depository Trust Company or its agent, the
initial Clearing Agency, by, or on behalf of, the Trust. Such Preferred
Securities Certificate or Certificates shall initially be registered on the
Securities Register in the name of Cede & Co., the nominee of the initial
Clearing Agency, and no Owner will receive a Definitive Preferred Securities
Certificate representing such Owner's interest in such Preferred Securities,
except as provided in Section 5.13. Unless and until Definitive Preferred
Securities Certificates have been issued to Owners pursuant to Section 5.13:

                         (i) the provisions of this Section 5.11(a) shall be in
full force and effect;

                         (ii) the Securities Registrar and the Trustees shall be
entitled to deal with the Clearing Agency for all purposes of this Trust
Agreement relating to the Book-Entry Preferred Securities Certificates
(including the payment of the Liquidation Amount of and Distributions on

                                       24

<PAGE>


the Book-Entry Preferred Securities and the giving of instructions or directions
to Owners of Book-Entry Preferred Securities) as the sole Holder of Book-Entry
Preferred Securities and shall have no obligations to the Owners thereof;

                         (iii) to the extent that the provisions of this Section
5.11 conflict with any other provisions of this Trust Agreement, the provisions
of this Section 5.11 shall control; and

                         (iv) the rights of the Owners of the Book-Entry
Preferred Securities Certificates shall be exercised only through the Clearing
Agency and shall be limited to those established by law and agreements between
such Owners and the Clearing Agency and/or the Clearing Agency Participants.
Pursuant to the Certificate Depository Agreement, unless and until Definitive
Preferred Securities Certificates are issued pursuant to Section 5.13, the
initial Clearing Agency will make book-entry transfers among the Clearing Agency
Participants and receive and transmit payments on the Preferred Securities to
such Clearing Agency Participants.

                  (b) A single Common Securities Certificate representing the
Common Securities shall be issued to the Depositor in the form of a definitive
Common Securities Certificate.

         Section 5.12      NOTICES TO CLEARING AGENCY.

         To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Trustees shall give all such notices and communications specified
herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.

         Section 5.13      DEFINITIVE PREFERRED SECURITIES CERTIFICATES.

         If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
with respect to the Preferred Securities Certificates, and the Depositor is
unable to locate a qualified successor, (b) the Depositor at its option advises
the Trustees in writing that it elects to terminate the book-entry system
through the Clearing Agency or (c) after the occurrence of a Debenture Event of
Default, Owners of Preferred Securities Certificates representing beneficial
interests aggregating at least a majority of the Liquidation Amount advise the
Administrative Trustees in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interest of the Owners of
Preferred Securities Certificates, then the Administrative Trustee shall notify
the Clearing Agency and the Clearing Agency shall notify all Owners of Preferred
Securities Certificates and the other Trustees of the occurrence of any such
event and of the availability of the Definitive Preferred Securities
Certificates to Owners of such class or classes, as applicable, requesting the
same. Upon surrender to the Administrative Trustees of the typewritten Preferred
Securities Certificate or Certificates representing the Book Entry Preferred
Securities Certificates by the Clearing Agency, accompanied by registration
instructions, the Administrative Trustees, or any one of them, shall execute the
Definitive Preferred Securities Certificates in accordance with the instructions
of the

                                       25

<PAGE>


Clearing Agency. Neither the Securities Registrar nor the Trustees shall be
liable for any delay in delivery of such instructions and may conclusively rely
on, and shall be protected in relying on, such instructions. Upon the issuance
of Definitive Preferred Securities Certificates, the Trustees shall recognize
the Holders of the Definitive Preferred Securities Certificates as
Securityholders. The Definitive Preferred Securities Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Administrative Trustees, as evidenced by the
execution thereof by the Administrative Trustees or any one of them.

         Section 5.14      RIGHTS OF SECURITYHOLDERS.

         (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement. The Trust Securities
shall have no preemptive or similar rights and when issued and delivered to
Securityholders against payment of the purchase price therefor will be fully
paid and nonassessable by the Trust. The Holders of the Trust Securities, in
their capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

         (b) For so long as any Preferred Securities remain Outstanding, if,
upon a Debenture Event of Default, the Debenture Trustee fails or the holders of
not less than 25% in principal amount of the outstanding Debentures fail to
declare the principal of all of the Debentures to be immediately due and
payable, the Holders of at least 25% in Liquidation Amount of the Preferred
Securities then Outstanding shall have such right by a notice in writing to the
Depositor and the Debenture Trustee; and upon any such declaration such
principal amount of and the accrued interest on all of the Debentures shall
become immediately due and payable, provided that the payment of principal and
interest on such Debentures shall remain subordinated to the extent provided in
the Indenture.

         At any time after such a declaration of acceleration with respect to
the Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Debenture Trustee as in the Indenture
provided, the Holders of a majority in Liquidation Amount of the Preferred
Securities, by written notice to the Property Trustee, the Depositor and the
Debenture Trustee, may rescind and annul such declaration and its consequences
if:

                         (i) the Depositor has paid or deposited with the
Debenture Trustee a sum sufficient to pay

                           (A) all overdue installments of interest (including
any Additional Interest (as defined in the Indenture)) on all of the Debentures,

                                       26

<PAGE>


                           (B) the principal of (and premium, if any, on) any
                  Debentures which have become due otherwise than by such
                  declaration of acceleration and interest thereon at the rate
                  borne by the Debentures, and

                           (C) all sums paid or advanced by the Debenture
                  Trustee under the Indenture and the reasonable compensation,
                  expenses, disbursements and advances of the Debenture Trustee
                  and the Property Trustee, their agents and counsel; and

                         (ii) all Events of Default with respect to the
Debentures, other than the non-payment of the principal of the Debentures which
has become due solely by such acceleration, have been cured or waived as
provided in Section 5.13 of the Indenture.

         The Holders of a majority in aggregate Liquidation Amount of the
Preferred Securities may, on behalf of the Holders of all the Preferred
Securities, waive any past default under the Indenture, except a default in the
payment of principal or interest (unless such default has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Debenture Trustee) or
a default in respect of a covenant or provision which under the Indenture cannot
be modified or amended without the consent of the holder of each outstanding
Debenture. No such rescission shall affect any subsequent default or impair any
right consequent thereon.

         Upon receipt by the Property Trustee of written notice declaring such
an acceleration, or rescission and annulment thereof, by Holders of the
Preferred Securities all or part of which is represented by Book-Entry Preferred
Securities Certificates, a record date shall be established for determining
Holders of Outstanding Preferred Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Property
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that, unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, that is
identical to a written notice which has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.14(b).

                  (c) For so long as any Preferred Securities remain
Outstanding, to the fullest extent permitted by law and subject to the terms of
this Trust Agreement and the Indenture, upon a Debenture Event of Default
specified in Section 5.1(1) or 5.1(2) of the Indenture, any Holder of Preferred
Securities shall have the right to institute a proceeding directly against the
Depositor, pursuant to Section 5.8 of the Indenture, for enforcement of payment
to such Holder of the principal amount of or interest on Debentures having a
principal amount equal to the Liquidation Amount of

                                       27

<PAGE>


the Preferred Securities of such Holder (a "Direct Action"). In connection
with any such Direct Action, the Holders of the Common Securities will be
subrogated to the rights of any Holder of the Preferred Securities to the
extent of any payment made by the Depositor to such Holder of Preferred
Securities as a result of such Direct Action. Except as set forth in Section
5.14(b) and (c), the Holders of Preferred Securities shall have no right to
exercise directly any right or remedy available to the holders of, or in
respect of, the Debentures.

                                   Article VI.

                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

         Section 6.1       LIMITATIONS ON VOTING RIGHTS.

                  (a) Except as provided in this Section, in Sections 5.14, 8.10
and 10.2 and in the Indenture and as otherwise required by law, no Holder of
Preferred Securities shall have any right to vote or in any manner otherwise
control the administration, operation and management of the Trust or the
obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Trust Securities Certificates, be construed so as
to constitute the Securityholders from time to time as partners or members of an
association.

                  (b) So long as any Debentures are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
executing any trust or power conferred on the Debenture Trustee with respect to
such Debentures, (ii) waive any past default which is waivable under Section
5.13 of the Indenture, (iii) exercise any right to rescind or annul a
declaration that the principal of all the Debentures shall be due and payable or
(iv) consent to any amendment, modification or termination of the Indenture or
the Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of at least a majority in
Liquidation Amount of all Outstanding Preferred Securities, provided, however,
that where a consent under the Indenture would require the consent of each
Holder of Debentures affected thereby, no such consent shall be given by the
Property Trustee without the prior written consent of each Holder of Preferred
Securities. The Trustees shall not revoke any action previously authorized or
approved by a vote of the Holders of Preferred Securities, except by a
subsequent vote of the Holders of Preferred Securities. The Property Trustee
shall notify all Holders of the Preferred Securities of any notice of default
received from the Debenture Trustee with respect to the Debentures. In addition
to obtaining the foregoing approvals of the Holders of the Preferred Securities,
prior to taking any of the foregoing actions, the Trustees shall, at the expense
of the Depositor, obtain an Opinion of Counsel experienced in such matters to
the effect that the Trust will not be classified as an association taxable as a
corporation for United States Federal income tax purposes on account of such
action.

                  (c) If any proposed amendment to the Trust Agreement provides
for, or the Trustees otherwise propose to effect, (i) any action that would
adversely affect in any material

                                       28

<PAGE>


respect the powers, preferences or special rights of the Preferred Securities,
whether by way of amendment to the Trust Agreement or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than pursuant to the
terms of this Trust Agreement, then the Holders of Outstanding Preferred
Securities as a class will be entitled to vote on such amendment or proposal and
such amendment or proposal shall not be effective except with the approval of
the Holders of at least a majority in Liquidation Amount of the Outstanding
Preferred Securities. Notwithstanding any other provision of this Trust
Agreement, no amendment to this Trust Agreement may be made if, as a result of
such amendment, the Trust would cause the Trust to fail or cause to be
classified as a grantor trust for United States Federal income tax purposes.

         Section 6.2       NOTICE OF MEETINGS.

         Notice of all meetings of the Preferred Securityholders, stating the
time, place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.8 to each Preferred Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting. At any such meeting, any business properly before the meeting may be so
considered whether or not stated in the notice of the meeting. Any adjourned
meeting may be held as adjourned without further notice.

         Section 6.3       MEETINGS OF PREFERRED SECURITYHOLDERS.

         No annual meeting of Securityholders is required to be held. The
Administrative Trustees, however, shall call a meeting of Securityholders to
vote on any matter upon the written request of the Preferred Securityholders of
record of 25% in Liquidation Amount of the Preferred Securities and the
Administrative Trustees or the Property Trustee may, at anytime in their
discretion, call a meeting of Preferred Securityholders to vote on any matters
as to which Preferred Securityholders are entitled to vote.

         Preferred Securityholders of record of 50% in Liquidation Amount of the
Outstanding Preferred Securities, present in person or by proxy, shall
constitute a quorum at any meeting of Securityholders.

         If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding more
than a majority of the Preferred Securities (based upon their Liquidation
Amount)held by the Preferred Securityholders of record present, either in person
or by proxy, at such meeting shall constitute the action of the Securityholders,
unless this Trust Agreement requires a greater number of affirmative votes.

         Section 6.4       VOTING RIGHTS.

         Securityholders shall be entitled to one vote for each $25 of
Liquidation Amount represented by their Trust Securities in respect of any
matter as to which such Securityholders are entitled to vote.

                                       29

<PAGE>


         Section 6.5       PROXIES, ETC.

         At any meeting of Securityholders, any Securityholder entitled to vote
thereat may vote by proxy, provided that no proxy shall be voted at any meeting
unless it shall have been placed on file with the Administrative Trustees, or
with such other officer or agent of the Trust as the Administrative Trustees may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of the Property Trustee, proxies may be solicited in
the name of the Property Trustee or one or more officers of the Property
Trustee. Only Securityholders of record shall be entitled to vote. When Trust
Securities are held jointly by several persons, any one of them may vote at any
meeting in person or by proxy in respect of such Trust Securities, but if more
than one of them shall be present at such meeting in person or by proxy, and
such joint owners or their proxies so present disagree as to any vote to be
cast, such vote shall not be received in respect of such Trust Securities. A
proxy purporting to be executed by or on behalf of a Securityholder shall be
deemed valid unless challenged at or prior to its exercise, and the burden of
proving invalidity shall rest on the challenger. No proxy shall be valid more
than three years after its date of execution.

         Section 6.6       SECURITYHOLDER ACTION BY WRITTEN CONSENT.

         Any action which may be taken by Securityholders at a meeting may be
taken without a meeting and without prior notice if Securityholders than a
majority of all Outstanding Trust Securities (based upon their Liquidation
Amount) entitled to vote in respect of such action (or such larger proportion
thereof as shall be required by any express provision of this Trust
Agreement) shall consent to the action in writing.

         Section 6.7       RECORD DATE FOR VOTING AND OTHER PURPOSES.

         For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate in
any distribution on the Trust Securities in respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, the Administrative Trustees may from time to time fix a date, not
more than 90 days prior to the date of any meeting of Securityholders or the
payment of a distribution or other action, as the case may be, as a record date
for the determination of the identity of the Securityholders of record for such
purposes

         Section 6.8       ACTS OF SECURITYHOLDERS.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Trust Agreement to be given, made
or taken by Securityholders or Owners may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Securityholders
or Owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred

                                       30

<PAGE>


to as the "Act" of the Securityholders or Owners signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Trust
Agreement and (subject to Section 8.1) conclusive in favor of the Trustees, if
made in the manner provided in this Section.

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

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

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

         Without limiting the foregoing, a Securityholder entitled hereunder to
take any action hereunder with regard to any particular Trust Security may do so
with regard to all or any part of the Liquidation Amount of such Trust Security
or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such liquidation amount.

         If any dispute shall arise between the Securityholders and the
Administrative Trustees or among such Securityholders or Trustees with respect
to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder or
Trustee under this Article VI, then the determination of such matter by the
Property Trustee shall be conclusive with respect to such matter.

         Section 6.9       INSPECTION OF RECORDS.

         Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Trust shall be open to inspection by Securityholders
during normal business hours for any purpose reasonably related to such
Securityholder's interest as a Securityholder.

                         REPRESENTATIONS AND WARRANTIES

         Section 7.1       REPRESENTATIONS AND WARRANTIES OF THE BANK, THE
                           PROPERTY TRUSTEE AND THE DELAWARE TRUSTEE.

Agreement and has taken all necessary action to authorize the execution,

the valid and legally binding agreement of each of the Property Trustee and the
Delaware Trustee enforceable against each of them in accordance with its terms,
subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting
creditors' rights and to general equity principles;

                  (f) the execution, delivery and performance of this Trust
Agreement has been duly authorized by all necessary corporate or other action on

<PAGE>


appropriate in context) or any order, judgment or decree applicable to the
Property Trustee or the Delaware Trustee;

                  (g) neither the authorization, execution or delivery by the
Property Trustee or the Delaware Trustee of this Trust Agreement nor the
consummation of any of the transactions by the Property Trustee or the Delaware
Trustee (as appropriate in context) contemplated herein or therein requires the
consent or approval of, the giving of notice to, the registration with or the

the Trust or would question the right, power and authority of the Property
Trustee or the Delaware Trustee, as the case may be, to enter into or perform
its obligations as one of the Trustees under this Trust Agreement.

         Section 7.2       REPRESENTATIONS AND WARRANTIES OF DEPOSITOR.

         The Depositor hereby represents and warrants for the benefit of the
Securityholders that (a) the Trust Securities Certificates issued at each Time

                                  Article VIII.

                                  THE TRUSTEES

         Section 8.1       CERTAIN DUTIES AND RESPONSIBILITIES.

                  (a) The duties and responsibilities of the Trustees shall be
as provided by this Trust Agreement and, in the case of the Property Trustee, by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any

                                       33

<PAGE>


of their duties hereunder, or in the exercise of any of their rights or powers,
if they 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. Whether or not therein expressly so provided, every provision of this
Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustees shall be subject to the provisions of this
Section. Nothing in this Trust Agreement shall be construed to release the
Property Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct. To the extent that, at law or in
equity, a Trustee has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to the Securityholders, such Trustee shall not
be liable to the Trustor to any Securityholder for such Trustee's good faith
reliance on the provisions of this Trust Agreement. The provisions of this Trust
Agreement, to the extent that they restrict the duties and liabilities of the
Trustees otherwise existing at law or in equity, are agreed by the Depositor and
the Securityholders to replace such other duties and liabilities of the
Trustees.

                  (b) All payments made by the Property Trustee or a Paying
Agent in respect of the Trust Securities shall be made only from the revenue and
proceeds from the Trust Property and only to the extent that there shall be
sufficient revenue or proceeds from the Trust Property to enable the Property
Trustee or a Paying Agent to make payments in accordance with the terms hereof.
Each Securityholder, by its acceptance of a Trust Security, agrees that it will
look solely to the revenue and proceeds from the Trust Property to the extent
legally available for distribution to it as herein provided and that the
Trustees are not personally liable to it for any amount distributable in respect
of any Trust Security or for any other liability in respect of any Trust
Security. This Section 8.1(b) does not limit the liability of the Trustees
expressly set forth elsewhere in this Trust Agreement or, in the case of the
Property Trustee, in the Trust Indenture Act.

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

                         (i) the Property Trustee shall not be liable for any
error of judgment made in good faith by an authorized officer of the Property
Trustee, unless it shall be proved that the Property Trustee was negligent in
ascertaining the pertinent facts;

                         (ii) the Property Trustee shall not be liable with
respect to any action taken or omitted to be taken by it in good faith in
accordance with the direction of the Holders of not less than a majority in
Liquidation Amount of the Trust Securities relating to the time, method and
place of conducting any proceeding for any remedy available to the Property
Trustee, or exercising any trust or power conferred upon the Property Trustee
under this Trust Agreement;

                         (iii) the Property Trustee's sole duty with respect to
the custody, safe keeping and physical preservation of the Debentures and the
Property Account shall be to deal with such Property in a similar manner as the
Property Trustee deals with similar property for its own account, subject to the
protections and limitations on liability afforded to the Property Trustee under
this Trust Agreement and the Trust Indenture Act;

                                       34

<PAGE>


                         (iv) the Property Trustee shall not be liable for any
interest on any money received by it except as it may otherwise agree with the
Depositor; and money held by the Property Trustee need not be segregated from
other funds held by it except in relation to the Property Account maintained by
the Property Trustee pursuant to Section 3.1 and except to the extent otherwise
required by law; and

                         (v) the Property Trustee shall not be responsible for
monitoring the compliance by the Administrative Trustees or the Depositor with
their respective duties under this Trust Agreement, nor shall the Property
Trustee be liable for the default or misconduct of the Administrative Trustees
or the Depositor.

         Section 8.2       CERTAIN NOTICES.

         Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.8, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived. Within five
Business Days after the receipt of notice of the Depositor's exercise of its
right to defer the payment of interest on the Debentures pursuant to the
Indenture, the Administrative Trustee shall transmit, in the manner and to the
extent provided in Section 10.8, notice of such exercise to the Securityholders
and the Property Trustee, unless such exercise shall have been revoked.

         Section 8.3       CERTAIN RIGHTS OF PROPERTY TRUSTEE.

         Subject to the provisions of Section 8.1:

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

                  (b) if (i) in performing its duties under this Trust Agreement
the Property Trustee is required to decide between alternative courses of action
or (ii) in construing any of the provisions of this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to which
the Preferred Securityholders are entitled to vote under the terms of this Trust
Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting written instructions of the Depositor as to the course of action to
be taken and the Property Trustee shall take such action, or refrain from taking
such action, as the Property Trustee shall be instructed in writing to take, or
to refrain from taking, by the Depositor; provided, however, that if the
Property Trustee does not receive such instructions of the Depositor within ten
Business Days after it has delivered such notice, or such reasonably

                                       35

<PAGE>


shorter period of time set forth in such notice (which to the extent practicable
shall not be less than two Business Days), it may, but shall be under no duty
to, take or refrain from taking such action not inconsistent with this Trust
Agreement as it shall deem advisable and in the best interests of the
Securityholders, in which event the Property Trustee shall have no liability
except for its own bad faith, negligence or willful misconduct;

                  (c) any direction or act of the Depositor or the
Administrative Trustees contemplated by this Trust Agreement shall be
sufficiently evidenced by an Officers' Certificate;

                  (d) whenever in the administration of this Trust Agreement,
the Property Trustee shall deem it desirable that a matter be established before
undertaking, suffering or omitting any action hereunder, the Property Trustee
(unless other evidence is herein specifically prescribed) may, in the absence of
bad faith on its part, request and rely upon an Officers' Certificate which,
upon receipt of such request, shall be promptly delivered by the Depositor or
the Administrative Trustees;

                  (e) the Property Trustee shall have no duty to see to any
recording, filing or registration of any instrument (including any financing or
continuation statement or any filing under tax or securities laws) or any
rerecording, refiling or reregistration thereof;

                  (f) the Property Trustee may consult with counsel (which
counsel may be counsel to the Depositor or any of its Affiliates, and may
include any of its employees) and the advice of such 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 and in
accordance with such advice, such counsel may be counsel to the Depositor or any
of its Affiliates, and may include any of its employees; the Property Trustee
shall have the right at any time to seek instructions concerning the
administration of this Trust Agreement from any court of competent jurisdiction;

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

                  (h) the Property 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, consent, order,
approval, bond, debenture, note or other evidence of indebtedness or other paper
or document, unless requested in writing to do so by one or more
Securityholders, but the Property Trustee may make such further inquiry or
investigation into such facts or matters as it may see fit;

                  (i) the Property Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or
through its agents or attorneys, provided that the Property Trustee shall be
responsible for its own negligence or recklessness with respect to selection of
any agent or attorney appointed by it hereunder;

                  (j) whenever in the administration of this Trust Agreement the
Property Trustee shall deem it desirable to receive instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request instructions from the Holders of the Trust Securities
which instructions may only be given by the Holders of the same proportion in
Liquidation Amount of the Trust Securities as would be entitled to direct the
Property Trustee under the terms of the Trust Securities in respect of such
remedy, right or action, (ii) may refrain from enforcing such remedy or right or
taking such other action until such instructions are received, and (iii) shall
be protected in acting in accordance with such instructions; and

                  (k) except as otherwise expressly provided by this Trust
Agreement, the Property Trustee shall not be under any obligation to take any
action that is discretionary under the provisions of this Trust Agreement.

         No provision of this Trust Agreement shall be deemed to impose any duty
or obligation on the Property Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any
such act or acts, or to exercise any such right, power, duty or obligation. No
permissive power or authority available to the Property Trustee shall be
construed to be a duty.

         Section 8.4       NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
SECURITIES.

         The recitals contained herein and in the Trust Securities Certificates
shall be taken as the statements of the Trust, and the Trustees do not assume
any responsibility for their correctness. The Trustees shall not be accountable
for the use or application by the Depositor of the proceeds of the Debentures.

         Section 8.5       MAY HOLD SECURITIES.

         Any Trustee or any other agent of any Trustee or the Trust, in its
individual or any other capacity, may become the owner or pledgee of Trust
Securities and, except as provided in the definition of the term
"Outstanding" in Article I and, subject to Sections 8.8 and 8.13, may
otherwise deal with the Trust with the same rights it would have if it were
not a Trustee or such other agent.

         Section 8.6       COMPENSATION; INDEMNITY; FEES.

         The Depositor agrees:

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

                  (b) except as otherwise expressly provided herein, to
reimburse the Trustees upon request for all reasonable expenses, disbursements
and advances incurred or made by the

                                       37

<PAGE>


Trustees in accordance with any provision of this Trust Agreement (including the
reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be
attributable to its negligence or bad faith; and

                  (c) to the fullest extent permitted by applicable law, to
indemnify and hold harmless (i) each Trustee, (ii) any Affiliate of any Trustee,
(iii) any officer, director, shareholder, employee, representative or agent of
any Trustee, and (iv) any employee or agent of the Trust or its Affiliates,
(referred to herein as an "Indemnified Person") from and against any loss,
damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by this Trust Agreement, except
that no Indemnified Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Indemnified Person by reason of
negligence or willful misconduct with respect to such acts or omissions.

                  (d) to the fullest extent permitted by applicable law, to
advance expenses (including legal fees) incurred by an Indemnified Person in
defending any claim, demand, action, suit or proceeding shall, from time to
time, prior to the final disposition of such claim, demand, action, suit or
proceeding upon receipt by the Depositor of (i) a written affirmation by or on
behalf of the Indemnified Person of its or his good faith belief that it or he
has met the standard of conduct set forth in this Section 8.6 and (ii) an
undertaking by or on behalf of the Indemnified Person to repay such amount if it
shall be determined that the Indemnified Person is not entitled to be
indemnified as authorized in the preceding subsection.

         The provisions of this Section 8.6 shall survive the termination of
this Trust Agreement.

         No Trustee may claim any lien or charge on any Trust Property as a
result of any amount due pursuant to this Section 8.6.

         The Depositor and any Trustee may, subject to Section 8.8, engage in or
possess an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the business of the
Trust, and the Trust and the Holders of Trust Securities shall have no rights by
virtue of this Trust Agreement in and to such independent ventures or the income
or profits derived therefrom, and the pursuit of any such venture, even if
competitive with the business of the Trust, shall not be deemed wrongful or
improper. Neither the Depositor, nor any Trustee, shall be obligated to present
any particular investment or other opportunity to the Trust even if such
opportunity is of a character that, if presented to the Trust, could be taken by
the Trust, and the Depositor or any Trustee shall have the right to take for its
own account(individually or as a partner or fiduciary) or to recommend to others
any such particular investment or other opportunity. Any Trustee may engage or
be interested in any financial or other transaction with the Depositor or any
Affiliate of the Depositor, or may act as depository for, trustee or agent for,
or act on any committee or body of holders of, securities or other obligations
of the Depositor or its Affiliates.

         Section 8.7       CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF
TRUSTEES.

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

                  (b) There shall at all times be one or more Administrative
Trustees hereunder with respect to the Trust Securities. Each Administrative
Trustee shall be either a natural person who is at least 21 years of age or a
legal entity that shall act through one or more persons authorized to bind that
entity.

                  (c) There shall at all times be a Delaware Trustee with
respect to the Trust Securities. The Delaware Trustee shall either be (i) a
natural person who is at least 21 years of age and a resident of the State of
Delaware or (ii) a legal entity with its principal place of business in the
State of Delaware and that otherwise meets the requirements of applicable
Delaware law that shall act through one or more persons authorized to bind such
entity.

         Section 8.8       CONFLICTING INTERESTS.

         If the Property Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement.

         Section 8.9       CO-TRUSTEES AND SEPARATE TRUSTEE.

         Unless an Event of Default shall have occurred and be continuing, at
anytime or times, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the Trust Property may
at the time be located, the Depositor and the Administrative Trustees, by agreed
action of the majority of such Trustees, shall have power to appoint, and upon
the written request of the Administrative Trustees, the Depositor shall for such
purpose join with the Administrative Trustees in the execution, delivery, and
performance of all instruments and agreements necessary or proper to appoint,
one or more Persons approved by the Property Trustee either to act as co-trustee
jointly with the Property Trustee, of all or any part of such Trust Property, or
to the extent required by law to act as separate trustee of any such property,
in either case with such powers as may be provided in the instrument of
appointment, and to vest in such Person or Persons in the capacity aforesaid,
any property, title, right or power deemed

                                       39

<PAGE>


necessary or desirable, subject to the other provisions of this Section. If the
Depositor does not join in such appointment within 15 days after the receipt by
it of a request so to do, or in case a Debenture Event of Default has occurred
and is continuing, the Property Trustee alone shall have power to make such
appointment. Any co-trustee or separate trustee appointed pursuant to this
Section shall either be (i) a natural person who is at least 21 years of age and
a resident of the United States or (ii) a legal entity with its principal place
of business in the United States that shall act through one or more persons
authorized to bind such entity.

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

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

                  (a) The Trust Securities shall be executed and delivered and
all rights, powers, duties, and obligations hereunder in respect of the custody
of securities, cash and other personal property held by, or required to be
deposited or pledged with, the Trustees specified hereunder, shall be exercised,
solely by such Trustees and not by such co-trustee or separate trustee.

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

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

                  (d) No co-trustee or separate trustee hereunder shall be
personally liable by reason of any act or omission of the Property Trustee or
any other trustee hereunder.

                                       40

<PAGE>


                  (e) The Property Trustee shall not be liable by reason of any
act of a co-trustee or separate trustee.

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

         Section 8.10      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         No resignation or removal of any Trustee (the "Relevant Trustee") and
no appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11.

         Subject to the immediately preceding paragraph, the Relevant Trustee
may resign at any time by giving written notice thereof to the Securityholders.
If the instrument of acceptance by the successor Trustee required by Section
8.11 shall not have been delivered to the Relevant Trustee within 30 days after
the giving of such notice of resignation, the Relevant Trustee may petition, at
the expense of the Trust, any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

         Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). An Administrative Trustee may
be removed by the Common Securityholder at any time.

         If any Trustee shall resign, be removed or become incapable of acting
as Trustee, or if a vacancy shall occur in the office of any Trustee for any
cause, at a time when no Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees, and the retiring Trustee shall comply with the applicable requirements
of Section 8.11. If the Property Trustee or the Delaware Trustee shall resign,
be removed or become incapable of continuing to act as the Property Trustee or
the Delaware Trustee, as the case may be, at a time when a Debenture Event of
Default shall have occurred and be continuing, the Preferred Securityholders, by
Act of the Securityholders of a majority in Liquidation Amount of the Preferred
Securities then Outstanding delivered to the retiring Relevant Trustee, shall
promptly appoint a successor Relevant Trustee or Trustees, and such successor
Trustee shall comply with the applicable requirements of Section 8.11. If an
Administrative Trustee shall resign, be removed or become incapable of acting as
Administrative Trustee, at a time when a Debenture Event of Default shall have
occurred and be continuing, the Common Securityholder by Act of the Common
Securityholder delivered to the Administrative Trustee shall promptly appoint a
successor Administrative Trustee or Administrative Trustees and such successor
Administrative Trustee or Trustees shall comply with the applicable

                                       41

<PAGE>


requirements of Section 8.11. If no successor Relevant Trustee shall have been
so appointed by the Common Securityholder or the Preferred Securityholders and
accepted appointment in the manner required by Section 8.11, any Securityholder
who has been a Securityholder of Trust Securities for at least six months may,
on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.

         The Property Trustee shall give notice of each resignation and each
removal of a Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 10.8 and shall give notice to
the Depositor. Each notice shall include the name of the successor Relevant
Trustee and the address of its Corporate Trust Office if it is the Property
Trustee.

         Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of remaining Administrative Trustees if
there are at least two of them or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Trustees or Delaware Trustee, as the case may be, set forth
in Section 8.7).

         Section 8.11      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         In case of the appointment hereunder of a successor Trustee such
successor Trustee so appointed shall execute, acknowledge and deliver to the
Trust and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Depositor or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and if the Property Trustee is the
resigning Trustee shall duly assign, transfer and deliver to the successor
Trustee all property and money held by such retiring Property Trustee hereunder.

         In case of the appointment hereunder of a successor Relevant Trustee,
the retiring Relevant Trustee and each successor Relevant Trustee with respect
to the Trust Securities shall execute and deliver an amendment hereto wherein
each successor Relevant Trustee shall accept such appointment and which (a)
shall contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Relevant Trustee all the rights,
powers, trusts and duties of the retiring Relevant Trustee with respect to the
Trust Securities and the Trust and (b) shall add to or change any of the
provisions of this Trust Agreement as shall be necessary to provide for or
facilitate the administration of the Trust by more than one Relevant Trustee, it
being understood that nothing herein or in such amendment shall constitute such
Relevant Trustees co-trustees and upon the execution and delivery of such
amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the

                                       42

<PAGE>


rights, powers, trusts and duties of the retiring Relevant Trustee; but, on
request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Relevant
Trustee all Trust Property, all proceeds thereof and money held by such retiring
Relevant Trustee hereunder with respect to the Trust Securities and the Trust.

         Upon request of any such successor Relevant Trustee, the Trust shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the first or second preceding paragraph, as the case may be. No
successor Relevant Trustee shall accept its appointment unless at the time of
such acceptance such successor Relevant Trustee shall be qualified and eligible
under this Article.

         Section 8.12      MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS.

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

         Section 8.13      PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR
OR TRUST.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Trust or any other obligor upon the
Trust Securities or the property of the Trust or of such other obligor or their
creditors, the Property Trustee (irrespective of whether any Distributions on
the Trust Securities shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Property Trustee shall
have made any demand on the Trust for the payment of any past due Distributions)
shall be entitled and empowered, to the fullest extent permitted by law, by
intervention in such proceeding or otherwise:

                  (a) to file and prove a claim for the whole amount of any
Distributions owing and unpaid in respect of the Trust Securities (or, if the
Trust Securities are Discount Securities, such portion of the liquidation amount
as may be specified in the terms of such Trust Securities) and to file such
other papers or documents as may be necessary or advisable in order to have the
claims of the Property Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel) and of the Holders allowed in such judicial proceeding, and

                  (b) to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Property Trustee and, in the event the
Property Trustee

                                       43

<PAGE>


shall consent to the making of such payments directly to the Holders, to pay to
the Property Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Property Trustee, its agents and
counsel, and any other amounts due the Property Trustee.

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

         Section 8.14      REPORTS BY PROPERTY TRUSTEE.

                  (a) Not later than July 15 of each year commencing with July
15, 1999, the Property Trustee shall transmit to all Securityholders in
accordance with Section 10.8, and to the Depositor, a brief report dated as of
such December 31 with respect to:

                         (i) its eligibility under Section 8.7 or, in lieu
thereof, if to the best of its knowledge it has continued to be eligible under
said Section, a written statement to such effect;

                         (ii) a statement that the Property Trustee has complied
with all of its obligations under this Trust Agreement during the twelve-month
period (or, in the case of the initial report, the period since the Closing
Date) ending with such December 31 or, if the Property Trustee has not complied
in any material respect with such obligations, a description of such
noncompliance; and

                         (iii) any change in the property and funds in its
possession as Property Trustee since the date of its last report and any action
taken by the Property Trustee in the performance of its duties hereunder which
it has not previously reported and which in its opinion materially affects the
Trust Securities.

                  (b) In addition the Property Trustee shall transmit to
Securityholders such reports concerning the Property Trustee and its actions
under this Trust Agreement as may be required pursuant to the Trust Indenture
Act at the times and in the manner provided pursuant thereto.

                  (c) A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Property Trustee with each national
stock exchange, the Nasdaq National Market or such other interdealer quotation
system or self-regulatory organization upon which the Trust Securities are
listed or traded, with the Commission and with the Depositor.

         Section 8.15      REPORTS TO THE PROPERTY TRUSTEE.

         The Depositor and the Administrative Trustees on behalf of the Trust

certificate required by Section 314(a) of the Trust

                                       44

         Section 8.16      EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.

         Each of the Depositor and the Administrative Trustees on behalf of the
Trust shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement that relate
to any of the matters set forth in Section 314 (c) of the Trust Indenture Act.
Any certificate or opinion required to be given by an officer pursuant to
Section 314(c)(1) of the Trust Indenture Act shall be given in the form of an
Officers' Certificate.

         Section 8.17      NUMBER OF TRUSTEES.

                  (a) The number of Trustees shall be four, provided that the
Holder of all of the Common Securities by written instrument may increase or
decrease the number of Administrative Trustees. The Property Trustee and the
Delaware Trustee may be the same Person.

                  (b) If a Trustee ceases to hold office for any reason and the
number of Administrative Trustees is not reduced pursuant to Section 8.17(a), or
if the number of Trustees is increased pursuant to Section 8.17(a), a vacancy
shall occur. The vacancy shall be filled with a Trustee appointed in accordance
with Section 8.10.

                  (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to annul, dissolve or terminate the Trust. Whenever a vacancy in the number of
Administrative Trustees shall occur, until such vacancy is filled by the
appointment of an Administrative Trustee in accordance with Section 8.10, the
Administrative Trustees in office, regardless of their number (and
notwithstanding any other provision of this Agreement), shall have all the
powers granted to the Administrative Trustees and shall discharge all the duties
imposed upon the Administrative Trustees by this Trust Agreement.

         Section 8.18      DELEGATION OF POWER.

                  (a) Any Administrative Trustee may, by power of attorney
consistent with applicable law, delegate to any other natural person over the
age of 21 his or her power for the purpose of executing any documents
contemplated in Section 2.7(a), including any registration statement or
amendment thereto filed with the Commission, or making any other governmental
filing; and

                  (b) The Administrative Trustees shall have power to delegate
from time to time to such of their number or to the Depositor the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Administrative Trustees or otherwise as the Administrative
Trustees may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of this Trust Agreement, as set
forth herein.

         Section 9.1       DISSOLUTION UPON EXPIRATION DATE.

         Unless earlier dissolved, the Trust shall automatically dissolve on
December 31, 2053 (the "Expiration Date"). Thereafter, the Trust Property shall
be distributed in accordance with Section 9.4.
         Section 9.2       EARLY TERMINATION.

         The first to occur of any of the following events is an "Early
Dissolution Event", the occurrence of which will cause a dissolution of the
Trust:

                  (a) the occurrence of a Bankruptcy Event in respect of, or the
dissolution or liquidation of, the Depositor;

                  (b) the written direction to the Property Trustee from the
Depositor at any time (which direction is optional and wholly within the
discretion of the Depositor) to dissolve the Trust and distribute Debentures to
Securityholders in exchange for the Preferred Securities;

                  (c) the redemption of all of the Preferred Securities in
connection with the redemption or maturity of all the Debentures; and

                  (d) the entry of an order for dissolution of the Trust by a
court of competent jurisdiction.

         Section 9.3       TERMINATION.

         The respective obligations and responsibilities of the Trustees and the
Trust created and continued hereby shall terminate upon the latest to occur of
the following: (a) the distribution by the Property Trustee to Securityholders
upon the liquidation of the Trust pursuant to Section 9.4, or upon the
redemption of all of the Trust Securities pursuant to Section 4.2, of all
amounts required to be distributed hereunder upon the final payment of the Trust
Securities; (b) the payment of any expenses owed by the Trust; and (c)the
discharge of all administrative duties of the Administrative Trustees, including
the performance of any tax reporting obligations with respect to the Trust or
the Securityholders.

         Section 9.4       LIQUIDATION.

                  (a) If an Early Dissolution Event specified in clause (a), (b)
or (d) of Section 9.2 occurs or upon the Expiration Date, the Trust shall be
liquidated by the Property Trustee as expeditiously as the Property Trustee
determines to be possible by distributing, after satisfaction of

                                       46

<PAGE>


liabilities to creditors of the Trust as provided by applicable law, to each
Securityholder a Like Amount of Debentures, subject to Section 9.4(d). Notice of
liquidation shall be given by the Property Trustee by first-class mail, postage
prepaid mailed not later than 30 nor more than 60 days prior to the Liquidation
Date to each Holder of Trust Securities at such Holder's address appearing in
the Securities Register. All notices of liquidation shall:

                         (i)        state the Liquidation Date;

                        (ii) state that from and after the Liquidation Date, the
Trust Securities will
no longer be deemed to be Outstanding and any Trust Securities Certificates not
surrendered for exchange will be deemed to represent a Like Amount of
Debentures; and

                       (iii)        provide such information with respect to the
mechanics by which Holders may exchange Trust Securities Certificates for
Debentures, or if Section 9.4(d) applies receive a Liquidation Distribution, as
the Administrative Trustees or the Property Trustee shall deem appropriate.

                  (b) Except where Section 9.2(c) or 9.4(d) applies, in order to
effect the liquidation of the Trust and distribution of the Debentures to
Securityholders, the Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

                  (c) Except where Section 9.2(c) or 9.4(d) applies, after the
Liquidation Date, (i) the Trust Securities will no longer be deemed to be
Outstanding, (ii) certificates representing a Like Amount of Debentures will be
issued to Holders of Trust Securities Certificates, upon surrender of such
certificates to the Administrative Trustees or their agent for exchange, (iii)
the Depositor shall use its reasonable efforts to have the Debentures listed on
the New York Stock Exchange or on such other exchange, interdealer quotation
system or self-regulatory organization as the Preferred Securities are then
listed, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on which
a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal will be made to Holders of Trust Securities
Certificates with respect to such Debentures) and (v) all rights of
Securityholders holding Trust Securities will cease, except the right of such
Securityholders to receive Debentures upon surrender of Trust Securities
Certificates.

                  (d) In the event that, notwithstanding the other provisions of
this Section 9.4, whether because of an order for dissolution entered by a court
of competent jurisdiction or otherwise, distribution of the Debentures in the
manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
wound-up by the Property Trustee in such manner as the Property Trustee
determines. In such

                                       47

<PAGE>

event, Securityholders will be entitled to receive out of the assets of the
Trust available for distribution to Securityholders, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, an amount
equal to the Liquidation Amount per Trust Security plus accumulated and unpaid
Distributions thereon to the date of payment (such amount being the "Liquidation
Distribution"). If, upon any such winding up the Liquidation Distribution can be
paid only in part because the Trust has insufficient assets available to pay in
full the aggregate Liquidation Distribution, then, subject to the next
succeeding sentence, the amounts payable by the Trust on the Trust Securities
shall be paid on a pro rata basis (based upon Liquidation Amounts). The holder
of the Common Securities will be entitled to receive Liquidation Distributions
upon any such winding-up pro rata (determined as aforesaid) with Holders of
Preferred Securities, except that, if a Debenture Event of Default has occurred
and is continuing, the Preferred Securities shall have a priority over the
Common Securities.

         Section 9.5       MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR
REPLACEMENTS OF THE TRUST.

         The Trust may not merge with or into, consolidate, convert into,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, except pursuant to this
Section 9.5 or Section 9.4. At the request of the Depositor, with the consent of
the Administrative Trustees and without the consent of the Holders of the
Preferred Securities, the Property Trustee or the Delaware Trustee, the Trust
may merge with or into, consolidate, convert into, amalgamate, or be replaced by
or convey, transfer or lease its properties and assets substantially as an
entirety to a trust organized as such under the laws of any State; provided,
that (i) such successor entity either (a) expressly assumes all of the
obligations of the Trust with respect to the Preferred Securities or (b)
substitutes for the Preferred Securities other securities having substantially
the same terms as the Preferred Securities (the "Successor Securities") so long
as the Successor Securities rank the same as the Preferred Securities rank in
priority with respect to distributions and payments upon liquidation, redemption
and otherwise, (ii) the Depositor expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of the Debentures, (iii) the Successor Securities are listed or traded,
or any Successor Securities will be listed upon notification of issuance, on any
national securities exchange or other organization on which the Preferred
Securities are then listed or traded, if any, (iv) such merger, consolidation,
conversion, amalgamation, replacement, conveyance, transfer or lease does not
cause the Preferred Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization, (v)
such merger, consolidation, conversion, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the Holders of the Preferred Securities (including any Successor
Securities) in any material respect, (vi) such successor entity has a purpose
substantially identical to that of the Trust, (vii) prior to such merger,
consolidation, conversion, amalgamation, replacement, conveyance, transfer or
lease, the Depositor has received an Opinion of Counsel to the effect that (a)
such merger, consolidation, conversion, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the Holders of the Preferred Securities (including any Successor
Securities) in any material respect, and (b)following such merger,
consolidation, conversion, amalgamation, replacement, conveyance, transfer or
lease, neither the Trust nor such successor entity will be required to register
as an investment company

                                       48

<PAGE>


under the 1940 Act and (viii) the Depositor owns all of the common securities
of such successor entity and guarantees the obligations of such successor
entity under the Successor Securities at least to the extent provided by the
Guarantee. Notwithstanding the foregoing, the Trust shall not, except with
the consent of Holders of 100% in Liquidation Amount of the Preferred
Securities, consolidate, amalgamate, convert into, merge with or into, or be
replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to any other entity or permit any other entity
to consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger, conversion, replacement, conveyance,
transfer or lease would cause the Trust or the successor entity to be
classified as other than a grantor trust for United States Federal income tax
purposes.

         Section 10.1      LIMITATION OF RIGHTS OF SECURITYHOLDERS.

         The death, dissolution, termination, bankruptcy or incapacity of any
Person having an interest, beneficial or otherwise, in Trust Securities shall
not operate to terminate this Trust Agreement, nor entitle the legal
successors, representatives or heirs of such Person or any Securityholder for
such Person, to claim an accounting, take any action or bring any proceeding
in any court for a partition or winding up of the arrangements contemplated
hereby, nor otherwise affect the rights, obligations and liabilities of the

consent of any Securityholders, (i) to cure any ambiguity, correct or supplement
any provision herein which may be inconsistent with any other provision herein,
or to make any other provisions with respect to matters or questions arising
under this Trust Agreement, which shall not be inconsistent with the other
provisions of this Trust Agreement, or (ii) to modify, eliminate or add to any
provisions of this Trust Agreement to such extent as shall be necessary to
ensure that the Trust will be classified for United States Federal income tax
purposes as a grantor trust at all times that any Trust Securities are
outstanding or to ensure that the Trust will not be required to register as an
investment company under the 1940 Act; provided, however, that in the case of
clause (i), such action shall not adversely affect in any material respect the
interests of any Securityholder, and any such amendments of this Trust Agreement
shall become effective when notice thereof is given to the Securityholders.

                  (b) Except as provided in Section 10.2(c) hereof, any
provision of this Trust Agreement may be amended by the Trustees and the
Depositor with (i) the consent of Trust Securityholders representing not less
than a majority (based upon Liquidation Amounts) of the Trust Securities then
Outstanding and (ii)receipt by the Trustees of an Opinion of Counsel to the
effect that such amendment or the exercise of any power granted to the Trustees
in accordance with such

                                     49

<PAGE>


amendment will not affect the Trust's status as a grantor trust for United
States Federal income tax purposes or the Trust's exemption from status of an
investment company under the 1940 Act.

Distribution on the Trust Securities or otherwise adversely affect the amount of

specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
paragraph (c) of this Section 10.2 may not be amended.

                  (d) Notwithstanding any other provisions of this Trust
Agreement, no Trustee shall enter into or consent to any amendment to this Trust
Agreement which would cause the Trust to fail or cease to qualify for the
exemption from status of an investment company under the 1940 Act or fail or
cease to be classified as a grantor trust for United States Federal income tax
purposes.

                  (e) Notwithstanding anything in this Trust Agreement to the
contrary, without the consent of the Depositor, this Trust Agreement may not be
amended in a manner which imposes any additional obligation on the Depositor.

                  (f) In the event that any amendment to this Trust Agreement is
made, the Administrative Trustees shall promptly provide to the Depositor a copy
of such amendment.

                  (g) Neither the Property Trustee nor the Delaware Trustee
shall be required to enter into any amendment to this Trust Agreement which
affects its own rights, duties or immunities under this Trust Agreement. The
Property Trustee shall be entitled to receive an Opinion of Counsel and an
Officers' Certificate stating that any amendment to this Trust Agreement is in
compliance with this Trust Agreement.

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

         Section 10.4      GOVERNING LAW.

         This Trust Agreement and the rights and obligations of each of the

         Section 10.9      AGREEMENT NOT TO PETITION.

         Each of the Trustees and the Depositor agree for the benefit of the
Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Depositor takes action in violation of this Section 10.9, the
Property Trustee agrees, for the benefit of Securityholders, that at the expense
of the Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Trust

for the purposes of the Trust Indenture Act.

         (c) If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Trust Agreement by any
of the provisions of the Trust Indenture Act, such required provision shall
control. If any provision of this Trust Agreement modifies or excludes any
provision of the Trust Indenture Act which may be so modified or excluded, the
latter provision shall be deemed to apply to this Trust Agreement as so modified
or excluded, as the case may be.

         (d) The application of the Trust Indenture Act to this Trust Agreement
shall not affect the nature of the Securities as equity securities representing
undivided beneficial interests in the assets of the Trust.

Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and

availability of certificates. In such event, the Issuer or the Transfer Agent
and Registrar shall issue, transfer and exchange certificates in appropriate
amounts, as required by DTC and others, and DTC agrees to cooperate fully with
the Issuer and the Transfer Agent and Registrar and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the

reasonably requested by the Issuer or the Transfer Agent and Registrar.

the extent provided herein, may conduct the business of the Trust, make and
execute contracts, and sue and be sued.

         2. The Depositor hereby assigns, transfers, conveys and sets over to

It is the intention of the parties hereto that the Trust created hereby
constitute a business trust under Chapter 38 of Title 12 of the Delaware Code,
12 DEL. C. ss. 3801, eT Seq. (the "Business Trust Act"), and that this document
constitute the governing instrument of the Trust. The Trustees are hereby
authorized and directed to execute and file a certificate of trust with the
Delaware Secretary of State in such form as the Trustees may approve.

         3. The Depositor and the Trustees will enter into an amended and
restated Trust Agreement satisfactory to each such party to provide for the
contemplated operation of the Trust created hereby and the issuance of the
Preferred Securities and Common Securities referred to therein. Prior to the
execution and delivery of such amended and restated Trust Agreement, the
Trustees shall not have any duty or obligation hereunder or with respect of the
trust estate, except as otherwise required by applicable law or as may be
necessary to obtain prior to such execution and delivery any licenses, consents
or approvals required by applicable law or otherwise. Notwithstanding the
foregoing, the Trustees may take all actions deemed proper as are necessary to
effect the transactions contemplated herein.

         4. The Depositor, as sponsor of the Trust, is hereby authorized, in its
discretion, (i) to prepare and file with the Securities and Exchange Commission
(the "Commission") and to execute, in the case of the 1933 Act Registration
Statement and 1934 Act Registration Statement (as herein defined), on behalf of
the Trust, (a) a Registration Statement (the "1933 Act Registration Statement"),
including all pre-effective and post-effective amendments thereto, relating to
the registration under the Securities Act of 1933, as amended (the "1933 Act"),

prospectus or supplement thereto relating to the Preferred Securities of the
Trust required to be filed pursuant to the 1933 Act, and (c) a Registration
Statement on Form 8-A or other appropriate form (the "1934 Act Registration
Statement"), including all pre-effective and post-effective amendments thereto,
relating to the registration of the Preferred Securities of the Trust under the
Securities Exchange Act of 1934, as amended; (ii) if and at such time as
determined by the Depositor, to file with the New York Stock Exchange or other
exchange, or the National Association of Securities Dealers ("NASD"), and
execute on behalf of the Trust a listing application and all other applications,

statements, certificates, agreements and other instruments as shall be necessary
or desirable to cause the Preferred Securities of the Trust to be listed on the
New York Stock Exchange or such other exchange, or the NASD's Nasdaq National
Market; (iii) to file and execute on behalf of the Trust, such applications,
reports, surety bonds, irrevocable consents, appointments of attorney for
service of process and other papers and documents that shall be necessary or
desirable to register the Preferred Securities of the Trust under the securities
or "Blue Sky" laws of such jurisdictions as the Depositor, on behalf of the
Trust, may deem necessary or desirable; (iv) to execute and deliver letters or
documents to, or instruments for filing with, a depository relating to the
Preferred Securities of the Trust; and (v) to execute, deliver and perform on
behalf of the Trust an underwriting agreement with one or more underwriters
relating to the offering of the Preferred Securities of the Trust.

         In the event that any filing referred to in this Section 4 is required
by the rules and regulations of the Commission, the New York Stock Exchange or
other exchange, NASD, or state securities or "Blue Sky" laws to be executed on
behalf of the Trust by the Trustees, the Trustees, in their capacity as trustees
of the Trust, are hereby authorized to join in any such filing and to execute on
behalf of the Trust any and all of the foregoing, it being understood that the
Trustees, in their capacity as trustees of the Trust, shall not be required to
join in any such filing or execute on behalf of the Trust any such document
unless required by the rules and regulations of the Commission, the New York
Stock Exchange or other exchange, NASD, or state securities or "Blue Sky" laws.

         5. This Trust Agreement may be executed in one or more counterparts.

         6. The number of trustees of the Trust initially shall be two and
thereafter the number of trustees of the Trust shall be such number as shall be
fixed from time to time by a written instrument signed by the Depositor which
may increase or decrease the number of trustees of the Trust; provided, however,
that to the extent required by the Business Trust Act, one trustee of the Trust
shall either be a natural person who is a resident of the State of Delaware or,
if not a natural person, an entity which has its principal place of business in
the State of Delaware. Subject to the foregoing, the Depositor is entitled to
appoint or remove without cause any trustee of the Trust at any time. Any
trustee of the Trust may resign upon thirty days' prior notice to the Depositor.

         7. The Depositor hereby agrees to (i) reimburse the Trustees for all
reasonable expenses (including reasonable fees and expenses of counsel and other
experts) and (ii) indemnify, defend and hold harmless the Trustees and any of
the officers, directors, employees and agents of the Trustees (the "Indemnified
Persons") from and against and all losses, damages, liabilities, claims,
actions, suits, costs, expenses, disbursements (including the reasonable fees
and expenses of counsel), taxes and penalties of any kind and nature whatsoever
(collectively, "Expenses"), to the extent that such Expenses arise out of or are
imposed upon or asserted at any time against such Indemnified Persons with
respect to the performance of this Trust Agreement, the creation, operation or
termination of the Trust or the transactions contemplated hereby; provided,
however, that the Depositor shall not be required to indemnify any Indemnified
Person

                                       -2-

gross negligence of such Indemnified Person.

accordance with, the laws of the State of Delaware (without regard to conflict
of laws principles).

         IN WITNESS WHEREOF, the parties hereto have caused this Trust Agreement
to be duly executed as of the day and year first above written.

Exchange or any other national stock exchange or the Nasdaq National Market for
listing upon notice of issuance of any Preferred Securities;

                         (iv) the preparation for filing by the Trust with the
Commission and the execution on behalf of the Trust of a registration statement
on Form 8-A relating to the registration of the Preferred Securities under
Section 12(b) or 12(g) of the Exchange Act, including any amendments thereto;

                         (v) the negotiation of the terms of, and the execution
and delivery of, the Underwriting Agreement providing for the sale of the
Preferred Securities; and

                         (vi) the taking of any other actions necessary or
desirable to carry out any of the foregoing activities.

                  (d) Notwithstanding anything herein to the contrary, the
Administrative Trustees are authorized and directed to conduct the affairs of
the Trust and to operate the Trust so that the Trust will not be deemed to be an
"investment company" required to be registered under the Investment Company Act
of 1940, as amended, or taxed as a corporation for United States Federal income
tax purposes and so that the Debentures will be treated as indebtedness of the
Depositor for United States Federal income tax purposes. In this connection, the
Depositor and the Administrative Trustees are authorized to take any action, not
inconsistent with applicable law, the Certificate of Trust or this Trust
Agreement, that each of the Depositor and the Administrative Trustees determines
in their discretion to be necessary or desirable for such purposes, as long as
such action does not adversely affect in any material respect the interests of
the Holders of the Preferred Securities.

         Section 2.8       ASSETS OF TRUST.

         The assets of the Trust shall consist of the Trust Property.

         Section 2.9       TITLE TO TRUST PROPERTY.

         Legal title to all Trust Property shall be vested at all times in the
Property Trustee (in its capacity as such) and shall be held and administered by
the Property Trustee for the benefit of the Trust and the Securityholders in
accordance with this Trust Agreement. The Holders shall not have legal title to
any part of the assets of the Trust, but shall have an undivided beneficial
ownership interest in the assets of the Trust.


                                  Article III.

                                PROPERTY ACCOUNT

         Section 3.1       PROPERTY ACCOUNT.

                  (a) On or prior to the Closing Date, the Property Trustee
shall establish the Property Account. The Property Trustee and any agent of the
Property Trustee shall have exclusive control and sole right of withdrawal with
respect to the Property Account for the purpose of making

                                       15

<PAGE>


deposits in and withdrawals from the Property Account in accordance with this
Trust Agreement. All monies and other property deposited or held from time to
time in the Property Account shall be held by the Property Trustee in the
Property Account for the exclusive benefit of the Securityholders and for
distribution as herein provided, including (and subject to) any priority of
payments provided for herein.

                  (b) The Property Trustee shall deposit in the Property
Account, promptly upon receipt, all payments of principal of or interest on, and
any other payments or proceeds with respect to, the Debentures. Amounts held in
the Property Account shall not be invested by the Property Trustee pending
distribution thereof.


                                   Article IV.

                            DISTRIBUTIONS; REDEMPTION

         Section 4.1       DISTRIBUTIONS.

                  (a) Distributions on the Trust Securities shall be cumulative,
and will accumulate whether or not there are funds of the Trust available for
the payment of Distributions. Distributions shall accrue from _________________,
________________, and, except in the event that the Depositor exercises its
right to defer the payment of interest on the Debentures pursuant to the
Indenture, shall be payable quarterly in arrears on March 31, June 30, September
30 and December 31 of each year, commencing on _____________________, 1999. If
any date on which a Distribution is otherwise payable on the Trust Securities is
not a Business Day, then the payment of such Distribution shall be made on the
next succeeding day that is a Business Day (and without any interest or other
payment in respect of any such delay) except that, if such Business Day is in
the next succeeding calendar year, payment of such Distribution shall be made on
the immediately preceding Business Day, in each case with the same force and
effect as if made on such date (each date on which distributions are payable in
accordance with this Section 4.1(a), a "Distribution Date").

                  (b) The Trust Securities represent undivided beneficial
interests in the Trust Property, and, as a practical matter, the Distributions
on the Trust Securities shall be payable at a rate of _____% per annum of the
Liquidation Amount of the Trust Securities. The amount of Distributions payable
for any full period shall be computed on the basis of a 360-day year of twelve
30-day months. The amount of Distributions for any partial period shall be
computed on the basis of the number of days elapsed in a 360-day year of twelve
30-day months. The amount of Distributions payable for any period shall include
the Additional Amounts, if any.

                  (c) Distributions on the Trust Securities shall be made by the
Property Trustee from the Property Account and shall be payable on each
Distribution Date only to the extent that the Trust has funds then on hand and
available in the Property Account for the payment of such Distributions.

                                       16

<PAGE>


                  (d) Distributions on the Trust Securities with respect to a
Distribution Date shall be payable to the Holders thereof as they appear on the
Securities Register for the Trust Securities on the relevant record date, which
shall be one Business Day prior to such Distribution Date; provided, however,
that in the event that the Preferred Securities do not remain in book-entry-only
form, the relevant record date shall be the date 15 days prior to the relevant
Distribution Date.

         Section 4.2       REDEMPTION.

                  (a) On each Debenture Redemption Date and on the stated
maturity of the Debentures, the Trust will be required to redeem a Like Amount
of Trust Securities at the Redemption Price.

                  (b) Notice of redemption shall be given by the Property
Trustee by first-class mail, postage prepaid, mailed not less than 30 nor more
than 60 days prior to the Redemption Date to each Holder of Trust Securities to
be redeemed, at such Holder's address appearing in the Security Register. All
notices of redemption shall state:

                         (i)        the Redemption Date;

                        (ii)        the Redemption Price;

                       (iii)        the CUSIP number;

                        (iv) if less than all the Outstanding Trust Securities
are to be redeemed, the identification and the total Liquidation Amount of the
particular Trust Securities to be redeemed; and

                         (v) that on the Redemption Date, the Redemption Price
will become due and payable upon each such Trust Security to be redeemed and
that distributions thereon will cease to accrue on and after said date.

                  (c) The Trust Securities redeemed on each Redemption Date
shall be redeemed at the Redemption Price with the proceeds from the
contemporaneous redemption of Debentures. Redemptions of the Trust Securities
shall be made and the Redemption Price shall be payable on each Redemption Date
only to the extent that the Trust has funds then on hand and available in the
Property Account for the payment of such Redemption Price.

                  (d) If the Property Trustee gives a notice of redemption in
respect of any Preferred Securities, then, by 12:00 noon, New York City time, on
the Redemption Date, [subject to Section 4.2(c),] the Property Trustee will, so
long as the Preferred Securities are in book-entry-only form, irrevocably
deposit with the Clearing Agency for the Preferred Securities funds sufficient
to pay the applicable Redemption Price and will give such Clearing Agency
irrevocable instructions and authority to pay the Redemption Price to the
Holders thereof. If the Preferred Securities are no longer in book-entry-only
form, the Property Trustee, [subject to Section

                                       17

<PAGE>


4.2(c),] will irrevocably deposit with the Paying Agent funds sufficient to pay
the applicable Redemption Price and will give the Paying Agent irrevocable
instructions and authority to pay the Redemption Price to the Holders thereof
upon surrender of their Preferred Securities Certificates. Notwithstanding the
foregoing, Distributions payable on or prior to the Redemption Date for any
Trust Securities called for redemption shall be payable to the Holders of such
Trust Securities as they appear on the Register for the Trust Securities on the
relevant record dates for the related Distribution Dates. If notice of
redemption shall have been given and funds deposited as required, then upon the
date of such deposit, all rights of Securityholders holding Trust Securities so
called for redemption will cease, except the right of such Securityholders to
receive the Redemption Price and any Distribution payable on or prior to the
Redemption Date, but without interest, and such Securities will cease to be
outstanding. In the event that any date on which any Redemption Price is payable
is not a Business Day, then payment of the Redemption Price payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay), except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day, in each case, with the same force and effect
as if made on such date. In the event that payment of the Redemption Price in
respect of any Trust Securities called for redemption is improperly withheld or
refused and not paid either by the Trust or by the Depositor pursuant to the
Guarantee, Distributions on such Trust Securities will continue to accrue, at
the then applicable rate, from the Redemption Date originally established by the
Trust for such Trust Securities to the date such Redemption Price is actually
paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.

                  (e) Payment of the Redemption Price on the Trust Securities
shall be made to the record holders thereof as they appear on the Securities
Register for the Trust Securities on the relevant record date, which shall be
one Business Day prior to the relevant Redemption Date; provided, however, that
in the event that the Preferred Securities do not remain in book-entry-only
form, the relevant record date shall be the date fifteen days prior to the
relevant Redemption Date.

                  (f) If, at any time, a Trust Special Event shall occur and be
continuing, the Administrative Trustees shall, unless the Debentures are
redeemed in the limited circumstances described below, within 90 days following
the occurrence of such Trust Special Event elect to either (i) dissolve the
Trust upon not less than 30 nor more than 60 days notice with the result that,
after satisfaction of creditors, if any, of the Trust, Debentures would be
distributed on a Pro Rata basis to the Holders of the Trust Preferred Securities
and the Trust Common Securities in liquidation of such Holders' interests in the
Trust; provided, however, that if at the time there is available to the Trust
the opportunity to eliminate, within such 90-day period, the Trust Special Event
by taking some ministerial action, such as filing a form or making an election,
or pursuing some other similar reasonable measure which in the sole judgment of
the Depositor has or will cause no adverse effect on the Trust, the Sponsor or
the Holders of the Trust Securities and will involve no material cost, the Trust
will pursue such measure in lieu of dissolution or (ii) cause the Preferred
Securities to remain outstanding; provided, that in the case of this clause
(ii), the Sponsor shall pay any and all expenses incurred by or payable by the
Trust attributable to the Trust Special Event. Furthermore, if in the case of
the occurrence of a Tax Event, the Administrative Trustees have received a Trust

                                       18

<PAGE>


Redemption Tax Opinion, then the Debenture Trustee shall have the right, within
90 days following the occurrence of such Tax Event, to elect to redeem the
Debentures in whole (but not in part) for cash upon not less than 30 nor more
than 60 days notice and promptly following such redemption, the Trust Securities
will be redeemed by the Trust at the Redemption Price as described in this
Section 4.2 below.

                  (g) If the Debentures are distributed to the Holders of the
Preferred Securities, the Depositor will use its best efforts to cause the
Debentures to be listed on the New York Stock Exchange or on such other national
securities exchange or similar organization as the Preferred Securities are then
listed or quoted.

                  (h) On the date fixed for any distribution of Debentures, upon
dissolution of the Trust, (i) the Preferred Securities and the Common Securities
will no longer be deemed to be outstanding and (ii) certificates representing
Trust Securities will be deemed to represent the Debentures having a liquidation
preference equal to the stated liquidation amount of such Trust Securities until
such certificates are presented to the Depositor or its agent for transfer or
reissuance.

                  (i) Subject to Section 4.3(a), if less than all the
Outstanding Trust Securities are to be redeemed on a Redemption Date, then the
aggregate Liquidation Amount of Trust Securities to be redeemed shall be
allocated on a pro rata basis (based on Liquidation Amounts) among the Common
Securities and the Preferred Securities. The particular Preferred Securities to
be redeemed shall be selected on a pro rata basis (based upon Liquidation
Amounts) not more than 60 days prior to the Redemption Date by the Property
Trustee from the Outstanding Preferred Securities not previously called for
redemption, by such method (including, without limitation, by lot) as the
Property Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to $25 or an integral multiple of
$25 in excess thereof) of the Liquidation Amount of Preferred Securities of a
denomination larger than $25. The Property Trustee shall promptly notify the
Security Registrar in writing of the Preferred Securities selected for
redemption and in the case of any Preferred Securities selected for partial
redemption, the Liquidation Amount thereof to be redeemed. For all purposes of
this Trust Agreement, unless the context otherwise requires, all provisions
relating to the redemption of Preferred Securities shall relate, in the case of
any Preferred Securities redeemed or to be redeemed only in part, to the portion
of the Liquidation Amount of Preferred Securities that has been or is to be
redeemed. [In any case, a failure to give such notice by mail or any defect in
the notice to the Holder of any Trust Security designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the
redemption of any other Trust Security.

         Section 4.3       SUBORDINATION OF COMMON SECURITIES.

                  (a) Payment of Distributions (including Additional Amounts, if
applicable) on, and the Redemption Price of, the Trust Securities, as
applicable, shall be made, subject to Section 4.2(i), pro rata among the Common
Securities and the Preferred Securities based on the Liquidation Amount of the
Trust Securities; provided, however, that if on any Distribution Date or
Redemption Date any Event of Default resulting from a Debenture Event of Default
shall have occurred and be

                                       19

<PAGE>


continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all
Outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all Outstanding Preferred Securities, shall have
been made or provided for and all funds immediately available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

                  (b) In the case of the occurrence of any Event of Default
resulting from any Debenture Event of Default, the Holder of Common Securities
will be deemed to have waived any right to act with respect to any such Event of
Default under this Trust Agreement until the effect of all such Events of
Default with respect to the Preferred Securities have been cured, waived or
otherwise eliminated. Until any such Event of Default under this Trust Agreement
with respect to the Preferred Securities has been so cured, waived or otherwise
eliminated, the Property Trustee shall act solely on behalf of the Holders of
the Preferred Securities and not the Holder of the Common Securities, and only
the Holders of the Preferred Securities will have the right to direct the
Property Trustee to act on their behalf.

         Section 4.4       PAYMENT PROCEDURES.

         Payments of Distributions (including Additional Amounts, if applicable)
in respect of the Preferred Securities shall be made by check mailed to the
address of the Person entitled thereto as such address shall appear on the
Securities Register or, if the Preferred Securities are held by a Clearing
Agency, such Distributions shall be made to the Clearing Agency in immediately
available funds, which shall credit the relevant Persons' accounts at such
Clearing Agency on the applicable distribution dates. Payments in respect of the
Common Securities shall be made in such manner as shall be mutually agreed
between the Property Trustee and the Common Securityholder.

         Section 4.5       TAX RETURNS AND REPORTS.

         The Administrative Trustees shall prepare (or cause to be prepared), at
the Depositor's expense, and file all United States Federal, state and local tax
and information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrative Trustees shall (a) prepare and file
(or cause to be prepared and filed) the appropriate Internal Revenue Service
Form required to be filed in respect of the Trust in each taxable year of the
Trust and (b) prepare and furnish (or cause to be prepared and furnished) to
each Securityholder the appropriate Internal Revenue Service form required to be
provided on such form. The Administrative Trustees shall provide the Depositor
and the Property Trustee with a copy of all such returns and reports promptly
after such filing or furnishing. The Trustees shall comply with United States
Federal withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Securityholders under the Trust
Securities.

under the Debentures of Additional Sums, the Property Trustee shall promptly pay

authority.

         Section 4.7       PAYMENTS UNDER INDENTURE.

         Any amount payable hereunder to any Holder of Preferred Securities
shall be reduced by the amount of any corresponding payment such Holder (and
Owner) has directly received pursuant to Section 5.8 of the Indenture.

manual signatures of individuals who were, at the time when such signatures
shall have been affixed, authorized to sign on behalf of the Trust, shall be
validly issued and entitled to the benefits of this Trust Agreement,
notwithstanding that such individuals or any of them shall have ceased to be so
authorized prior to the delivery of such Trust Securities Certificates or did
not hold such offices at the date of delivery of such Trust Securities
Certificates. A transferee of a Trust Securities Certificate shall become a
Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 5.4, 5.11

Administrative Trustee and the Securities Registrar duly executed by the Holder
or his attorney duly authorized in writing. Each Preferred Securities
Certificate surrendered for registration of transfer or exchange shall be
cancelled and subsequently disposed of by an Administrative Trustee in
accordance with such Person's customary practice. No service charge shall be
made for any registration of transfer or exchange of Preferred Securities
Certificates, but the Securities Registrar may require payment of a sum
sufficient to cover any tax or governmental charge that maybe imposed in
connection with any transfer or exchange of Preferred Securities Certificates.

to the Securities Registrar, or if the Securities Registrar shall receive
evidence to its satisfaction of the destruction, loss or theft of any Trust
Securities Certificate and (b) there shall be delivered to the Securities
Registrar and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees, or any one of them, on behalf of the
Trust shall execute and make available for delivery, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a
new Trust Securities Certificate of like class, tenor and denomination. In
connection with the issuance of any new Trust

to the contrary.

         Section 5.7       ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND
ADDRESSES.

address, regardless of the source from which such information was derived.

         Section 5.8       MAINTENANCE OF OFFICE OR AGENCY.

         The Administrative Trustees shall maintain an office or offices or

The Administrative Trustees initially designate Sierra Pacific Resources, P.O.
Box 30150 (6100 Neil Road), Reno, Nevada 89520-3150, Attn: __________, as its

shall give prompt written notice to the Depositor and to the Securityholders of
any change in the location of the Securities Register or any such office or
agency.

         Section 5.9       APPOINTMENT OF PAYING AGENT.

         The Paying Agent shall make distributions to Securityholders from the
Property Account and shall report the amounts of such distributions to the
Property Trustee and the Administrative Trustees. Any Paying Agent shall have
the revocable power to withdraw funds from the Property Account for the purpose
of making the distributions referred to above. The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust Agreement in any material respect. The Paying Agent
shall initially be the Bank, and any co-paying agent chosen by the Bank, and
acceptable to the Administrative Trustees and the Depositor. Any Person acting

notice to the Administrative Trustees, the Property Trustee and the Depositor.
In the event that the Bank shall no longer be the Paying Agent or a successor
Paying Agent shall resign or its authority to act be revoked, the Administrative
Trustees shall appoint a successor that is acceptable to the Property Trustee
and the Depositor to act as Paying Agent (which shall be a bank or trust
company). The Administrative Trustees shall cause such successor Paying Agent or
any additional Paying Agent appointed by the Administrative Trustees to execute
and deliver to the Trustees an instrument in which such successor Paying Agent
or additional Paying Agent shall agree with the Trustees that as Paying Agent,
such successor Paying Agent or additional Paying Agent will hold all sums, if
any, held by it for payment to the Securityholders in trust for the benefit of
the Securityholders entitled thereto until such sums shall be paid to such
Securityholders. The Paying Agent shall return all unclaimed funds to the
Property Trustee and upon removal of a Paying Agent such Paying Agent shall also
return all funds in its possession to the Property Trustee. The provisions of
Sections 8.1, 8.3 and 8.6 herein shall apply to the Bank also in its role as
Paying Agent, for so long as the Bank shall act as Paying Agent and, to the
extent applicable, to any other paying agent appointed hereunder. Any reference
in this Agreement to the Paying Agent shall include any co-paying agent unless
the context requires otherwise.

         At each Time of Delivery, the Depositor shall acquire and retain
beneficial and record ownership of the Common Securities. To the fullest extent
permitted by law, other than a transfer in connection with a transaction
permitted by Section 8.1 of the Indenture, any attempted transfer of the Common
Securities shall be void. The Administrative Trustees shall cause each Common
Securities Certificate issued to the Depositor to contain a legend stating "THIS
CERTIFICATE IS NOT TRANSFERABLE OTHER THAN IN ACCORDANCE WITH THE TRUST
AGREEMENT (DEFINED BELOW)".

         Section 5.11      BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON
SECURITIES CERTIFICATE.

                  (a) The Preferred Securities Certificates, upon original
issuance, will be issued in the form of a typewritten Preferred Securities
Certificate or Certificates representing Book-Entry Preferred Securities
Certificates, to be delivered to The Depository Trust Company or its agent, the
initial Clearing Agency, by, or on behalf of, the Trust. Such Preferred
Securities Certificate or Certificates shall initially be registered on the
Securities Register in the name of Cede & Co., the nominee of the initial
Clearing Agency, and no Owner will receive a Definitive Preferred Securities
Certificate representing such Owner's interest in such Preferred Securities,
except as provided in Section 5.13. Unless and until Definitive Preferred
Securities Certificates have been issued to Owners pursuant to Section 5.13:

                         (i) the provisions of this Section 5.11(a) shall be in
full force and effect;

                         (ii) the Securities Registrar and the Trustees shall be
entitled to deal with the Clearing Agency for all purposes of this Trust
Agreement relating to the Book-Entry Preferred Securities Certificates
(including the payment of the Liquidation Amount of and Distributions on

                                       24

<PAGE>


the Book-Entry Preferred Securities and the giving of instructions or directions
to Owners of Book-Entry Preferred Securities) as the sole Holder of Book-Entry
Preferred Securities and shall have no obligations to the Owners thereof;

                         (iii) to the extent that the provisions of this Section
5.11 conflict with any other provisions of this Trust Agreement, the provisions
of this Section 5.11 shall control; and

                         (iv) the rights of the Owners of the Book-Entry
Preferred Securities Certificates shall be exercised only through the Clearing
Agency and shall be limited to those established by law and agreements between
such Owners and the Clearing Agency and/or the Clearing Agency Participants.
Pursuant to the Certificate Depository Agreement, unless and until Definitive
Preferred Securities Certificates are issued pursuant to Section 5.13, the
initial Clearing Agency will make book-entry transfers among the Clearing Agency
Participants and receive and transmit payments on the Preferred Securities to
such Clearing Agency Participants.

                  (b) A single Common Securities Certificate representing the
Common Securities shall be issued to the Depositor in the form of a definitive
Common Securities Certificate.

         Section 5.12      NOTICES TO CLEARING AGENCY.

         To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Trustees shall give all such notices and communications specified
herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.

         Section 5.13      DEFINITIVE PREFERRED SECURITIES CERTIFICATES.

         If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
with respect to the Preferred Securities Certificates, and the Depositor is
unable to locate a qualified successor, (b) the Depositor at its option advises
the Trustees in writing that it elects to terminate the book-entry system
through the Clearing Agency or (c) after the occurrence of a Debenture Event of
Default, Owners of Preferred Securities Certificates representing beneficial
interests aggregating at least a majority of the Liquidation Amount advise the
Administrative Trustees in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interest of the Owners of
Preferred Securities Certificates, then the Administrative Trustee shall notify
the Clearing Agency and the Clearing Agency shall notify all Owners of Preferred
Securities Certificates and the other Trustees of the occurrence of any such
event and of the availability of the Definitive Preferred Securities
Certificates to Owners of such class or classes, as applicable, requesting the
same. Upon surrender to the Administrative Trustees of the typewritten Preferred
Securities Certificate or Certificates representing the Book Entry Preferred
Securities Certificates by the Clearing Agency, accompanied by registration
instructions, the Administrative Trustees, or any one of them, shall execute the
Definitive Preferred Securities Certificates in accordance with the instructions
of the

                                       25

<PAGE>


Clearing Agency. Neither the Securities Registrar nor the Trustees shall be
liable for any delay in delivery of such instructions and may conclusively rely
on, and shall be protected in relying on, such instructions. Upon the issuance
of Definitive Preferred Securities Certificates, the Trustees shall recognize
the Holders of the Definitive Preferred Securities Certificates as
Securityholders. The Definitive Preferred Securities Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Administrative Trustees, as evidenced by the
execution thereof by the Administrative Trustees or any one of them.

         Section 5.14      RIGHTS OF SECURITYHOLDERS.

         (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement. The Trust Securities
shall have no preemptive or similar rights and when issued and delivered to
Securityholders against payment of the purchase price therefor will be fully
paid and nonassessable by the Trust. The Holders of the Trust Securities, in
their capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

         (b) For so long as any Preferred Securities remain Outstanding, if,
upon a Debenture Event of Default, the Debenture Trustee fails or the holders of
not less than 25% in principal amount of the outstanding Debentures fail to
declare the principal of all of the Debentures to be immediately due and
payable, the Holders of at least 25% in Liquidation Amount of the Preferred
Securities then Outstanding shall have such right by a notice in writing to the
Depositor and the Debenture Trustee; and upon any such declaration such
principal amount of and the accrued interest on all of the Debentures shall
become immediately due and payable, provided that the payment of principal and
interest on such Debentures shall remain subordinated to the extent provided in
the Indenture.

         At any time after such a declaration of acceleration with respect to
the Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Debenture Trustee as in the Indenture
provided, the Holders of a majority in Liquidation Amount of the Preferred
Securities, by written notice to the Property Trustee, the Depositor and the
Debenture Trustee, may rescind and annul such declaration and its consequences
if:

                         (i) the Depositor has paid or deposited with the
Debenture Trustee a sum sufficient to pay

                           (A) all overdue installments of interest (including
any Additional Interest (as defined in the Indenture)) on all of the Debentures,

                                       26

<PAGE>


                           (B) the principal of (and premium, if any, on) any
                  Debentures which have become due otherwise than by such
                  declaration of acceleration and interest thereon at the rate
                  borne by the Debentures, and

                           (C) all sums paid or advanced by the Debenture
                  Trustee under the Indenture and the reasonable compensation,
                  expenses, disbursements and advances of the Debenture Trustee
                  and the Property Trustee, their agents and counsel; and

                         (ii) all Events of Default with respect to the
Debentures, other than the non-payment of the principal of the Debentures which
has become due solely by such acceleration, have been cured or waived as
provided in Section 5.13 of the Indenture.

         The Holders of a majority in aggregate Liquidation Amount of the
Preferred Securities may, on behalf of the Holders of all the Preferred
Securities, waive any past default under the Indenture, except a default in the
payment of principal or interest (unless such default has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Debenture Trustee) or
a default in respect of a covenant or provision which under the Indenture cannot
be modified or amended without the consent of the holder of each outstanding
Debenture. No such rescission shall affect any subsequent default or impair any
right consequent thereon.

         Upon receipt by the Property Trustee of written notice declaring such
an acceleration, or rescission and annulment thereof, by Holders of the
Preferred Securities all or part of which is represented by Book-Entry Preferred
Securities Certificates, a record date shall be established for determining
Holders of Outstanding Preferred Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Property
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that, unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, that is
identical to a written notice which has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.14(b).

                  (c) For so long as any Preferred Securities remain
Outstanding, to the fullest extent permitted by law and subject to the terms of
this Trust Agreement and the Indenture, upon a Debenture Event of Default
specified in Section 5.1(1) or 5.1(2) of the Indenture, any Holder of Preferred
Securities shall have the right to institute a proceeding directly against the
Depositor, pursuant to Section 5.8 of the Indenture, for enforcement of payment
to such Holder of the principal amount of or interest on Debentures having a
principal amount equal to the Liquidation Amount of

                                       27

<PAGE>


the Preferred Securities of such Holder (a "Direct Action"). In connection
with any such Direct Action, the Holders of the Common Securities will be
subrogated to the rights of any Holder of the Preferred Securities to the
extent of any payment made by the Depositor to such Holder of Preferred
Securities as a result of such Direct Action. Except as set forth in Section
5.14(b) and (c), the Holders of Preferred Securities shall have no right to
exercise directly any right or remedy available to the holders of, or in
respect of, the Debentures.

                                   Article VI.

                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

         Section 6.1       LIMITATIONS ON VOTING RIGHTS.

                  (a) Except as provided in this Section, in Sections 5.14, 8.10
and 10.2 and in the Indenture and as otherwise required by law, no Holder of
Preferred Securities shall have any right to vote or in any manner otherwise
control the administration, operation and management of the Trust or the
obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Trust Securities Certificates, be construed so as
to constitute the Securityholders from time to time as partners or members of an
association.

                  (b) So long as any Debentures are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
executing any trust or power conferred on the Debenture Trustee with respect to
such Debentures, (ii) waive any past default which is waivable under Section
5.13 of the Indenture, (iii) exercise any right to rescind or annul a
declaration that the principal of all the Debentures shall be due and payable or
(iv) consent to any amendment, modification or termination of the Indenture or
the Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of at least a majority in
Liquidation Amount of all Outstanding Preferred Securities, provided, however,
that where a consent under the Indenture would require the consent of each
Holder of Debentures affected thereby, no such consent shall be given by the
Property Trustee without the prior written consent of each Holder of Preferred
Securities. The Trustees shall not revoke any action previously authorized or
approved by a vote of the Holders of Preferred Securities, except by a
subsequent vote of the Holders of Preferred Securities. The Property Trustee
shall notify all Holders of the Preferred Securities of any notice of default
received from the Debenture Trustee with respect to the Debentures. In addition
to obtaining the foregoing approvals of the Holders of the Preferred Securities,
prior to taking any of the foregoing actions, the Trustees shall, at the expense
of the Depositor, obtain an Opinion of Counsel experienced in such matters to
the effect that the Trust will not be classified as an association taxable as a
corporation for United States Federal income tax purposes on account of such
action.

                  (c) If any proposed amendment to the Trust Agreement provides
for, or the Trustees otherwise propose to effect, (i) any action that would
adversely affect in any material

                                       28

<PAGE>


respect the powers, preferences or special rights of the Preferred Securities,
whether by way of amendment to the Trust Agreement or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than pursuant to the
terms of this Trust Agreement, then the Holders of Outstanding Preferred
Securities as a class will be entitled to vote on such amendment or proposal and
such amendment or proposal shall not be effective except with the approval of
the Holders of at least a majority in Liquidation Amount of the Outstanding
Preferred Securities. Notwithstanding any other provision of this Trust
Agreement, no amendment to this Trust Agreement may be made if, as a result of
such amendment, the Trust would cause the Trust to fail or cause to be
classified as a grantor trust for United States Federal income tax purposes.

         Section 6.2       NOTICE OF MEETINGS.

         Notice of all meetings of the Preferred Securityholders, stating the
time, place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.8 to each Preferred Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting. At any such meeting, any business properly before the meeting may be so
considered whether or not stated in the notice of the meeting. Any adjourned
meeting may be held as adjourned without further notice.

         Section 6.3       MEETINGS OF PREFERRED SECURITYHOLDERS.

         No annual meeting of Securityholders is required to be held. The
Administrative Trustees, however, shall call a meeting of Securityholders to
vote on any matter upon the written request of the Preferred Securityholders of
record of 25% in Liquidation Amount of the Preferred Securities and the
Administrative Trustees or the Property Trustee may, at anytime in their
discretion, call a meeting of Preferred Securityholders to vote on any matters
as to which Preferred Securityholders are entitled to vote.

         Preferred Securityholders of record of 50% in Liquidation Amount of the
Outstanding Preferred Securities, present in person or by proxy, shall
constitute a quorum at any meeting of Securityholders.

         If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding more
than a majority of the Preferred Securities (based upon their Liquidation
Amount)held by the Preferred Securityholders of record present, either in person
or by proxy, at such meeting shall constitute the action of the Securityholders,
unless this Trust Agreement requires a greater number of affirmative votes.

         Section 6.4       VOTING RIGHTS.

         Securityholders shall be entitled to one vote for each $25 of
Liquidation Amount represented by their Trust Securities in respect of any
matter as to which such Securityholders are entitled to vote.

                                       29

<PAGE>


         Section 6.5       PROXIES, ETC.

         At any meeting of Securityholders, any Securityholder entitled to vote
thereat may vote by proxy, provided that no proxy shall be voted at any meeting
unless it shall have been placed on file with the Administrative Trustees, or
with such other officer or agent of the Trust as the Administrative Trustees may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of the Property Trustee, proxies may be solicited in
the name of the Property Trustee or one or more officers of the Property
Trustee. Only Securityholders of record shall be entitled to vote. When Trust
Securities are held jointly by several persons, any one of them may vote at any
meeting in person or by proxy in respect of such Trust Securities, but if more
than one of them shall be present at such meeting in person or by proxy, and
such joint owners or their proxies so present disagree as to any vote to be
cast, such vote shall not be received in respect of such Trust Securities. A
proxy purporting to be executed by or on behalf of a Securityholder shall be
deemed valid unless challenged at or prior to its exercise, and the burden of
proving invalidity shall rest on the challenger. No proxy shall be valid more
than three years after its date of execution.

         Section 6.6       SECURITYHOLDER ACTION BY WRITTEN CONSENT.

         Any action which may be taken by Securityholders at a meeting may be
taken without a meeting and without prior notice if Securityholders than a
majority of all Outstanding Trust Securities (based upon their Liquidation
Amount) entitled to vote in respect of such action (or such larger proportion
thereof as shall be required by any express provision of this Trust
Agreement) shall consent to the action in writing.

         Section 6.7       RECORD DATE FOR VOTING AND OTHER PURPOSES.

         For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate in
any distribution on the Trust Securities in respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, the Administrative Trustees may from time to time fix a date, not
more than 90 days prior to the date of any meeting of Securityholders or the
payment of a distribution or other action, as the case may be, as a record date
for the determination of the identity of the Securityholders of record for such
purposes

         Section 6.8       ACTS OF SECURITYHOLDERS.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Trust Agreement to be given, made
or taken by Securityholders or Owners may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Securityholders
or Owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred

                                       30

<PAGE>


to as the "Act" of the Securityholders or Owners signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Trust
Agreement and (subject to Section 8.1) conclusive in favor of the Trustees, if
made in the manner provided in this Section.

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

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

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

         Without limiting the foregoing, a Securityholder entitled hereunder to
take any action hereunder with regard to any particular Trust Security may do so
with regard to all or any part of the Liquidation Amount of such Trust Security
or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such liquidation amount.

         If any dispute shall arise between the Securityholders and the
Administrative Trustees or among such Securityholders or Trustees with respect
to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder or
Trustee under this Article VI, then the determination of such matter by the
Property Trustee shall be conclusive with respect to such matter.

         Section 6.9       INSPECTION OF RECORDS.

         Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Trust shall be open to inspection by Securityholders
during normal business hours for any purpose reasonably related to such
Securityholder's interest as a Securityholder.

         Section 8.1       CERTAIN DUTIES AND RESPONSIBILITIES.

                  (a) The duties and responsibilities of the Trustees shall be

Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any

                                       33

<PAGE>


of their duties hereunder, or in the exercise of any of their rights or powers,
if they 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. Whether or not therein expressly so provided, every provision of this
Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustees shall be subject to the provisions of this
Section. Nothing in this Trust Agreement shall be construed to release the
Property Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct. To the extent that, at law or in
equity, a Trustee has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to the Securityholders, such Trustee shall not
be liable to the Trustor to any Securityholder for such Trustee's good faith
reliance on the provisions of this Trust Agreement. The provisions of this Trust
Agreement, to the extent that they restrict the duties and liabilities of the
Trustees otherwise existing at law or in equity, are agreed by the Depositor and
the Securityholders to replace such other duties and liabilities of the
Trustees.

                  (b) All payments made by the Property Trustee or a Paying
Agent in respect of the Trust Securities shall be made only from the revenue and
proceeds from the Trust Property and only to the extent that there shall be
sufficient revenue or proceeds from the Trust Property to enable the Property
Trustee or a Paying Agent to make payments in accordance with the terms hereof.
Each Securityholder, by its acceptance of a Trust Security, agrees that it will
look solely to the revenue and proceeds from the Trust Property to the extent
legally available for distribution to it as herein provided and that the
Trustees are not personally liable to it for any amount distributable in respect
of any Trust Security or for any other liability in respect of any Trust
Security. This Section 8.1(b) does not limit the liability of the Trustees
expressly set forth elsewhere in this Trust Agreement or, in the case of the
Property Trustee, in the Trust Indenture Act.

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

                         (i) the Property Trustee shall not be liable for any
error of judgment made in good faith by an authorized officer of the Property
Trustee, unless it shall be proved that the Property Trustee was negligent in
ascertaining the pertinent facts;

                         (ii) the Property Trustee shall not be liable with
respect to any action taken or omitted to be taken by it in good faith in
accordance with the direction of the Holders of not less than a majority in
Liquidation Amount of the Trust Securities relating to the time, method and
place of conducting any proceeding for any remedy available to the Property
Trustee, or exercising any trust or power conferred upon the Property Trustee
under this Trust Agreement;

                         (iii) the Property Trustee's sole duty with respect to
the custody, safe keeping and physical preservation of the Debentures and the
Property Account shall be to deal with such Property in a similar manner as the
Property Trustee deals with similar property for its own account, subject to the
protections and limitations on liability afforded to the Property Trustee under
this Trust Agreement and the Trust Indenture Act;

                                       34

<PAGE>


                         (iv) the Property Trustee shall not be liable for any
interest on any money received by it except as it may otherwise agree with the
Depositor; and money held by the Property Trustee need not be segregated from
other funds held by it except in relation to the Property Account maintained by
the Property Trustee pursuant to Section 3.1 and except to the extent otherwise
required by law; and

                         (v) the Property Trustee shall not be responsible for
monitoring the compliance by the Administrative Trustees or the Depositor with
their respective duties under this Trust Agreement, nor shall the Property
Trustee be liable for the default or misconduct of the Administrative Trustees
or the Depositor.

         Section 8.2       CERTAIN NOTICES.

         Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.8, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived. Within five
Business Days after the receipt of notice of the Depositor's exercise of its
right to defer the payment of interest on the Debentures pursuant to the
Indenture, the Administrative Trustee shall transmit, in the manner and to the
extent provided in Section 10.8, notice of such exercise to the Securityholders
and the Property Trustee, unless such exercise shall have been revoked.

         Section 8.3       CERTAIN RIGHTS OF PROPERTY TRUSTEE.

         Subject to the provisions of Section 8.1:

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

                  (b) if (i) in performing its duties under this Trust Agreement
the Property Trustee is required to decide between alternative courses of action
or (ii) in construing any of the provisions of this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to which
the Preferred Securityholders are entitled to vote under the terms of this Trust
Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting written instructions of the Depositor as to the course of action to
be taken and the Property Trustee shall take such action, or refrain from taking
such action, as the Property Trustee shall be instructed in writing to take, or
to refrain from taking, by the Depositor; provided, however, that if the
Property Trustee does not receive such instructions of the Depositor within ten
Business Days after it has delivered such notice, or such reasonably

                                       35

<PAGE>


shorter period of time set forth in such notice (which to the extent practicable
shall not be less than two Business Days), it may, but shall be under no duty
to, take or refrain from taking such action not inconsistent with this Trust
Agreement as it shall deem advisable and in the best interests of the
Securityholders, in which event the Property Trustee shall have no liability
except for its own bad faith, negligence or willful misconduct;

                  (c) any direction or act of the Depositor or the
Administrative Trustees contemplated by this Trust Agreement shall be
sufficiently evidenced by an Officers' Certificate;

                  (d) whenever in the administration of this Trust Agreement,
the Property Trustee shall deem it desirable that a matter be established before
undertaking, suffering or omitting any action hereunder, the Property Trustee
(unless other evidence is herein specifically prescribed) may, in the absence of
bad faith on its part, request and rely upon an Officers' Certificate which,
upon receipt of such request, shall be promptly delivered by the Depositor or
the Administrative Trustees;

                  (e) the Property Trustee shall have no duty to see to any
recording, filing or registration of any instrument (including any financing or
continuation statement or any filing under tax or securities laws) or any
rerecording, refiling or reregistration thereof;

                  (f) the Property Trustee may consult with counsel (which
counsel may be counsel to the Depositor or any of its Affiliates, and may
include any of its employees) and the advice of such 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 and in
accordance with such advice, such counsel may be counsel to the Depositor or any
of its Affiliates, and may include any of its employees; the Property Trustee
shall have the right at any time to seek instructions concerning the
administration of this Trust Agreement from any court of competent jurisdiction;

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

                  (h) the Property 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, consent, order,
approval, bond, debenture, note or other evidence of indebtedness or other paper
or document, unless requested in writing to do so by one or more
Securityholders, but the Property Trustee may make such further inquiry or
investigation into such facts or matters as it may see fit;

                  (i) the Property Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or
through its agents or attorneys, provided that the Property Trustee shall be
responsible for its own negligence or recklessness with respect to selection of
any agent or attorney appointed by it hereunder;

                                       36

<PAGE>


                  (j) whenever in the administration of this Trust Agreement the
Property Trustee shall deem it desirable to receive instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request instructions from the Holders of the Trust Securities
which instructions may only be given by the Holders of the same proportion in
Liquidation Amount of the Trust Securities as would be entitled to direct the
Property Trustee under the terms of the Trust Securities in respect of such
remedy, right or action, (ii) may refrain from enforcing such remedy or right or
taking such other action until such instructions are received, and (iii) shall
be protected in acting in accordance with such instructions; and

                  (k) except as otherwise expressly provided by this Trust
Agreement, the Property Trustee shall not be under any obligation to take any
action that is discretionary under the provisions of this Trust Agreement.

         No provision of this Trust Agreement shall be deemed to impose any duty
or obligation on the Property Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any
such act or acts, or to exercise any such right, power, duty or obligation. No
permissive power or authority available to the Property Trustee shall be
construed to be a duty.

         Section 8.4       NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
SECURITIES.

         The recitals contained herein and in the Trust Securities Certificates
shall be taken as the statements of the Trust, and the Trustees do not assume
any responsibility for their correctness. The Trustees shall not be accountable
for the use or application by the Depositor of the proceeds of the Debentures.

         Section 8.5       MAY HOLD SECURITIES.

         Any Trustee or any other agent of any Trustee or the Trust, in its
individual or any other capacity, may become the owner or pledgee of Trust
Securities and, except as provided in the definition of the term
"Outstanding" in Article I and, subject to Sections 8.8 and 8.13, may
otherwise deal with the Trust with the same rights it would have if it were
not a Trustee or such other agent.

         Section 8.6       COMPENSATION; INDEMNITY; FEES.

         The Depositor agrees:

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

                  (b) except as otherwise expressly provided herein, to
reimburse the Trustees upon request for all reasonable expenses, disbursements
and advances incurred or made by the

                                       37

<PAGE>


Trustees in accordance with any provision of this Trust Agreement (including the
reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be
attributable to its negligence or bad faith; and

                  (c) to the fullest extent permitted by applicable law, to
indemnify and hold harmless (i) each Trustee, (ii) any Affiliate of any Trustee,
(iii) any officer, director, shareholder, employee, representative or agent of
any Trustee, and (iv) any employee or agent of the Trust or its Affiliates,
(referred to herein as an "Indemnified Person") from and against any loss,
damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by this Trust Agreement, except
that no Indemnified Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Indemnified Person by reason of
negligence or willful misconduct with respect to such acts or omissions.

                  (d) to the fullest extent permitted by applicable law, to
advance expenses (including legal fees) incurred by an Indemnified Person in
defending any claim, demand, action, suit or proceeding shall, from time to
time, prior to the final disposition of such claim, demand, action, suit or
proceeding upon receipt by the Depositor of (i) a written affirmation by or on
behalf of the Indemnified Person of its or his good faith belief that it or he
has met the standard of conduct set forth in this Section 8.6 and (ii) an
undertaking by or on behalf of the Indemnified Person to repay such amount if it
shall be determined that the Indemnified Person is not entitled to be
indemnified as authorized in the preceding subsection.

         The provisions of this Section 8.6 shall survive the termination of
this Trust Agreement.

         No Trustee may claim any lien or charge on any Trust Property as a
result of any amount due pursuant to this Section 8.6.

         The Depositor and any Trustee may, subject to Section 8.8, engage in or
possess an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the business of the
Trust, and the Trust and the Holders of Trust Securities shall have no rights by
virtue of this Trust Agreement in and to such independent ventures or the income
or profits derived therefrom, and the pursuit of any such venture, even if
competitive with the business of the Trust, shall not be deemed wrongful or
improper. Neither the Depositor, nor any Trustee, shall be obligated to present
any particular investment or other opportunity to the Trust even if such
opportunity is of a character that, if presented to the Trust, could be taken by
the Trust, and the Depositor or any Trustee shall have the right to take for its
own account(individually or as a partner or fiduciary) or to recommend to others
any such particular investment or other opportunity. Any Trustee may engage or
be interested in any financial or other transaction with the Depositor or any
Affiliate of the Depositor, or may act as depository for, trustee or agent for,
or act on any committee or body of holders of, securities or other obligations
of the Depositor or its Affiliates.

         Section 8.7       CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF
TRUSTEES.

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

                  (b) There shall at all times be one or more Administrative
Trustees hereunder with respect to the Trust Securities. Each Administrative
Trustee shall be either a natural person who is at least 21 years of age or a
legal entity that shall act through one or more persons authorized to bind that
entity.

                  (c) There shall at all times be a Delaware Trustee with
respect to the Trust Securities. The Delaware Trustee shall either be (i) a
natural person who is at least 21 years of age and a resident of the State of
Delaware or (ii) a legal entity with its principal place of business in the
State of Delaware and that otherwise meets the requirements of applicable
Delaware law that shall act through one or more persons authorized to bind such
entity.

         Section 8.8       CONFLICTING INTERESTS.

         If the Property Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement.

         Section 8.9       CO-TRUSTEES AND SEPARATE TRUSTEE.

         Unless an Event of Default shall have occurred and be continuing, at
anytime or times, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the Trust Property may
at the time be located, the Depositor and the Administrative Trustees, by agreed
action of the majority of such Trustees, shall have power to appoint, and upon
the written request of the Administrative Trustees, the Depositor shall for such
purpose join with the Administrative Trustees in the execution, delivery, and
performance of all instruments and agreements necessary or proper to appoint,
one or more Persons approved by the Property Trustee either to act as co-trustee
jointly with the Property Trustee, of all or any part of such Trust Property, or
to the extent required by law to act as separate trustee of any such property,
in either case with such powers as may be provided in the instrument of
appointment, and to vest in such Person or Persons in the capacity aforesaid,
any property, title, right or power deemed

                                       39

<PAGE>


necessary or desirable, subject to the other provisions of this Section. If the
Depositor does not join in such appointment within 15 days after the receipt by
it of a request so to do, or in case a Debenture Event of Default has occurred
and is continuing, the Property Trustee alone shall have power to make such
appointment. Any co-trustee or separate trustee appointed pursuant to this
Section shall either be (i) a natural person who is at least 21 years of age and
a resident of the United States or (ii) a legal entity with its principal place
of business in the United States that shall act through one or more persons
authorized to bind such entity.

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

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

                  (a) The Trust Securities shall be executed and delivered and
all rights, powers, duties, and obligations hereunder in respect of the custody
of securities, cash and other personal property held by, or required to be
deposited or pledged with, the Trustees specified hereunder, shall be exercised,
solely by such Trustees and not by such co-trustee or separate trustee.

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

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

                  (d) No co-trustee or separate trustee hereunder shall be
personally liable by reason of any act or omission of the Property Trustee or
any other trustee hereunder.

                                       40

<PAGE>


                  (e) The Property Trustee shall not be liable by reason of any
act of a co-trustee or separate trustee.

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

         Section 8.10      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         No resignation or removal of any Trustee (the "Relevant Trustee") and
no appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11.

         Subject to the immediately preceding paragraph, the Relevant Trustee
may resign at any time by giving written notice thereof to the Securityholders.
If the instrument of acceptance by the successor Trustee required by Section
8.11 shall not have been delivered to the Relevant Trustee within 30 days after
the giving of such notice of resignation, the Relevant Trustee may petition, at
the expense of the Trust, any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

         Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). An Administrative Trustee may
be removed by the Common Securityholder at any time.

         If any Trustee shall resign, be removed or become incapable of acting
as Trustee, or if a vacancy shall occur in the office of any Trustee for any
cause, at a time when no Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees, and the retiring Trustee shall comply with the applicable requirements
of Section 8.11. If the Property Trustee or the Delaware Trustee shall resign,
be removed or become incapable of continuing to act as the Property Trustee or
the Delaware Trustee, as the case may be, at a time when a Debenture Event of
Default shall have occurred and be continuing, the Preferred Securityholders, by
Act of the Securityholders of a majority in Liquidation Amount of the Preferred
Securities then Outstanding delivered to the retiring Relevant Trustee, shall
promptly appoint a successor Relevant Trustee or Trustees, and such successor
Trustee shall comply with the applicable requirements of Section 8.11. If an
Administrative Trustee shall resign, be removed or become incapable of acting as
Administrative Trustee, at a time when a Debenture Event of Default shall have
occurred and be continuing, the Common Securityholder by Act of the Common
Securityholder delivered to the Administrative Trustee shall promptly appoint a
successor Administrative Trustee or Administrative Trustees and such successor
Administrative Trustee or Trustees shall comply with the applicable

                                       41

<PAGE>


requirements of Section 8.11. If no successor Relevant Trustee shall have been
so appointed by the Common Securityholder or the Preferred Securityholders and
accepted appointment in the manner required by Section 8.11, any Securityholder
who has been a Securityholder of Trust Securities for at least six months may,
on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.

         The Property Trustee shall give notice of each resignation and each
removal of a Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 10.8 and shall give notice to
the Depositor. Each notice shall include the name of the successor Relevant
Trustee and the address of its Corporate Trust Office if it is the Property
Trustee.

         Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of remaining Administrative Trustees if
there are at least two of them or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Trustees or Delaware Trustee, as the case may be, set forth
in Section 8.7).

         Section 8.11      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         In case of the appointment hereunder of a successor Trustee such
successor Trustee so appointed shall execute, acknowledge and deliver to the
Trust and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Depositor or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and if the Property Trustee is the
resigning Trustee shall duly assign, transfer and deliver to the successor
Trustee all property and money held by such retiring Property Trustee hereunder.

         In case of the appointment hereunder of a successor Relevant Trustee,
the retiring Relevant Trustee and each successor Relevant Trustee with respect
to the Trust Securities shall execute and deliver an amendment hereto wherein
each successor Relevant Trustee shall accept such appointment and which (a)
shall contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Relevant Trustee all the rights,
powers, trusts and duties of the retiring Relevant Trustee with respect to the
Trust Securities and the Trust and (b) shall add to or change any of the
provisions of this Trust Agreement as shall be necessary to provide for or
facilitate the administration of the Trust by more than one Relevant Trustee, it
being understood that nothing herein or in such amendment shall constitute such
Relevant Trustees co-trustees and upon the execution and delivery of such
amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the

                                       42

<PAGE>


rights, powers, trusts and duties of the retiring Relevant Trustee; but, on
request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Relevant
Trustee all Trust Property, all proceeds thereof and money held by such retiring
Relevant Trustee hereunder with respect to the Trust Securities and the Trust.

         Upon request of any such successor Relevant Trustee, the Trust shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the first or second preceding paragraph, as the case may be. No
successor Relevant Trustee shall accept its appointment unless at the time of
such acceptance such successor Relevant Trustee shall be qualified and eligible
under this Article.

         Section 8.12      MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS.

         Any corporation into which the Property Trustee or the Delaware Trustee
maybe merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which such
Relevant Trustee shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of such Relevant Trustee, shall
be the successor of such Relevant Trustee hereunder, provided such corporation

         Section 8.13      PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR
OR TRUST.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Trust or any other obligor upon the
Trust Securities or the property of the Trust or of such other obligor or their
creditors, the Property Trustee (irrespective of whether any Distributions on
the Trust Securities shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Property Trustee shall
have made any demand on the Trust for the payment of any past due Distributions)
shall be entitled and empowered, to the fullest extent permitted by law, by
intervention in such proceeding or otherwise:

                  (a) to file and prove a claim for the whole amount of any
Distributions owing and unpaid in respect of the Trust Securities (or, if the
Trust Securities are Discount Securities, such portion of the liquidation amount
as may be specified in the terms of such Trust Securities) and to file such
other papers or documents as may be necessary or advisable in order to have the
claims of the Property Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel) and of the Holders allowed in such judicial proceeding, and

                  (b) to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Property Trustee and, in the event the
Property Trustee

                                       43

<PAGE>


shall consent to the making of such payments directly to the Holders, to pay to
the Property Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Property Trustee, its agents and
counsel, and any other amounts due the Property Trustee.

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

                  (a) Not later than July 15 of each year commencing with July

such December 31 with respect to:

                         (i) its eligibility under Section 8.7 or, in lieu

said Section, a written statement to such effect;

                         (ii) a statement that the Property Trustee has complied
with all of its obligations under this Trust Agreement during the twelve-month
period (or, in the case of the initial report, the period since the Closing
Date) ending with such December 31 or, if the Property Trustee has not complied
in any material respect with such obligations, a description of such
noncompliance; and

                         (iii) any change in the property and funds in its
possession as Property Trustee since the date of its last report and any action
taken by the Property Trustee in the performance of its duties hereunder which
it has not previously reported and which in its opinion materially affects the
Trust Securities.

                  (b) In addition the Property Trustee shall transmit to
Securityholders such reports concerning the Property Trustee and its actions
under this Trust Agreement as may be required pursuant to the Trust Indenture
Act at the times and in the manner provided pursuant thereto.

                  (c) A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Property Trustee with each national
stock exchange, the Nasdaq National Market or such other interdealer quotation
system or self-regulatory organization upon which the Trust Securities are
listed or traded, with the Commission and with the Depositor.

         Section 8.15      REPORTS TO THE PROPERTY TRUSTEE.

         Section 8.16      EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.

         Each of the Depositor and the Administrative Trustees on behalf of the
Trust shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement that relate
to any of the matters set forth in Section 314 (c) of the Trust Indenture Act.
Any certificate or opinion required to be given by an officer pursuant to

Officers' Certificate.

         Section 8.17      NUMBER OF TRUSTEES.

                  (a) The number of Trustees shall be four, provided that the
Holder of all of the Common Securities by written instrument may increase or
decrease the number of Administrative Trustees. The Property Trustee and the
Delaware Trustee may be the same Person.

                  (b) If a Trustee ceases to hold office for any reason and the
number of Administrative Trustees is not reduced pursuant to Section 8.17(a), or
if the number of Trustees is increased pursuant to Section 8.17(a), a vacancy
shall occur. The vacancy shall be filled with a Trustee appointed in accordance
with Section 8.10.

                  (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to annul, dissolve or terminate the Trust. Whenever a vacancy in the number of
Administrative Trustees shall occur, until such vacancy is filled by the
appointment of an Administrative Trustee in accordance with Section 8.10, the
Administrative Trustees in office, regardless of their number (and
notwithstanding any other provision of this Agreement), shall have all the
powers granted to the Administrative Trustees and shall discharge all the duties
imposed upon the Administrative Trustees by this Trust Agreement.

         Section 8.18      DELEGATION OF POWER.

                  (a) Any Administrative Trustee may, by power of attorney

                  (b) The Administrative Trustees shall have power to delegate
from time to time to such of their number or to the Depositor the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Administrative Trustees or otherwise as the Administrative
Trustees may deem expedient, to the extent such delegation is not prohibited by

                                   Article IX.

                       DISSOLUTION, LIQUIDATION AND MERGER

         Section 9.1       DISSOLUTION UPON EXPIRATION DATE.

         Unless earlier dissolved, the Trust shall automatically dissolve on
December 31, 2053 (the "Expiration Date"). Thereafter, the Trust Property shall
be distributed in accordance with Section 9.4.
         Section 9.2       EARLY TERMINATION.

         The first to occur of any of the following events is an "Early
Dissolution Event", the occurrence of which will cause a dissolution of the
Trust:

                  (a) the occurrence of a Bankruptcy Event in respect of, or the
dissolution or liquidation of, the Depositor;

                  (b) the written direction to the Property Trustee from the
Depositor at any time (which direction is optional and wholly within the
discretion of the Depositor) to dissolve the Trust and distribute Debentures to
Securityholders in exchange for the Preferred Securities;

                  (c) the redemption of all of the Preferred Securities in
connection with the redemption or maturity of all the Debentures; and

                  (d) the entry of an order for dissolution of the Trust by a
court of competent jurisdiction.

         Section 9.3       TERMINATION.

         The respective obligations and responsibilities of the Trustees and the
Trust created and continued hereby shall terminate upon the latest to occur of
the following: (a) the distribution by the Property Trustee to Securityholders
upon the liquidation of the Trust pursuant to Section 9.4, or upon the
redemption of all of the Trust Securities pursuant to Section 4.2, of all
amounts required to be distributed hereunder upon the final payment of the Trust
Securities; (b) the payment of any expenses owed by the Trust; and (c)the
discharge of all administrative duties of the Administrative Trustees, including
the performance of any tax reporting obligations with respect to the Trust or
the Securityholders.

         Section 9.4       LIQUIDATION.

                  (a) If an Early Dissolution Event specified in clause (a), (b)
or (d) of Section 9.2 occurs or upon the Expiration Date, the Trust shall be
liquidated by the Property Trustee as expeditiously as the Property Trustee
determines to be possible by distributing, after satisfaction of

                                       46

<PAGE>


liabilities to creditors of the Trust as provided by applicable law, to each
Securityholder a Like Amount of Debentures, subject to Section 9.4(d). Notice of
liquidation shall be given by the Property Trustee by first-class mail, postage
prepaid mailed not later than 30 nor more than 60 days prior to the Liquidation
Date to each Holder of Trust Securities at such Holder's address appearing in
the Securities Register. All notices of liquidation shall:

                         (i)        state the Liquidation Date;

                        (ii) state that from and after the Liquidation Date, the
Trust Securities will
no longer be deemed to be Outstanding and any Trust Securities Certificates not
surrendered for exchange will be deemed to represent a Like Amount of
Debentures; and

                       (iii)        provide such information with respect to the
mechanics by which Holders may exchange Trust Securities Certificates for
Debentures, or if Section 9.4(d) applies receive a Liquidation Distribution, as
the Administrative Trustees or the Property Trustee shall deem appropriate.

                  (b) Except where Section 9.2(c) or 9.4(d) applies, in order to
effect the liquidation of the Trust and distribution of the Debentures to
Securityholders, the Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

                  (c) Except where Section 9.2(c) or 9.4(d) applies, after the
Liquidation Date, (i) the Trust Securities will no longer be deemed to be
Outstanding, (ii) certificates representing a Like Amount of Debentures will be
issued to Holders of Trust Securities Certificates, upon surrender of such
certificates to the Administrative Trustees or their agent for exchange, (iii)
the Depositor shall use its reasonable efforts to have the Debentures listed on
the New York Stock Exchange or on such other exchange, interdealer quotation
system or self-regulatory organization as the Preferred Securities are then
listed, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on which
a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal will be made to Holders of Trust Securities
Certificates with respect to such Debentures) and (v) all rights of
Securityholders holding Trust Securities will cease, except the right of such
Securityholders to receive Debentures upon surrender of Trust Securities
Certificates.

                  (d) In the event that, notwithstanding the other provisions of
this Section 9.4, whether because of an order for dissolution entered by a court
of competent jurisdiction or otherwise, distribution of the Debentures in the
manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
wound-up by the Property Trustee in such manner as the Property Trustee
determines. In such

                                       47

<PAGE>

event, Securityholders will be entitled to receive out of the assets of the
Trust available for distribution to Securityholders, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, an amount
equal to the Liquidation Amount per Trust Security plus accumulated and unpaid
Distributions thereon to the date of payment (such amount being the "Liquidation
Distribution"). If, upon any such winding up the Liquidation Distribution can be
paid only in part because the Trust has insufficient assets available to pay in
full the aggregate Liquidation Distribution, then, subject to the next
succeeding sentence, the amounts payable by the Trust on the Trust Securities
shall be paid on a pro rata basis (based upon Liquidation Amounts). The holder
of the Common Securities will be entitled to receive Liquidation Distributions
upon any such winding-up pro rata (determined as aforesaid) with Holders of
Preferred Securities, except that, if a Debenture Event of Default has occurred
and is continuing, the Preferred Securities shall have a priority over the
Common Securities.

         Section 9.5       MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR
REPLACEMENTS OF THE TRUST.

         The Trust may not merge with or into, consolidate, convert into,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, except pursuant to this
Section 9.5 or Section 9.4. At the request of the Depositor, with the consent of
the Administrative Trustees and without the consent of the Holders of the
Preferred Securities, the Property Trustee or the Delaware Trustee, the Trust
may merge with or into, consolidate, convert into, amalgamate, or be replaced by
or convey, transfer or lease its properties and assets substantially as an
entirety to a trust organized as such under the laws of any State; provided,
that (i) such successor entity either (a) expressly assumes all of the
obligations of the Trust with respect to the Preferred Securities or (b)
substitutes for the Preferred Securities other securities having substantially
the same terms as the Preferred Securities (the "Successor Securities") so long
as the Successor Securities rank the same as the Preferred Securities rank in
priority with respect to distributions and payments upon liquidation, redemption
and otherwise, (ii) the Depositor expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of the Debentures, (iii) the Successor Securities are listed or traded,
or any Successor Securities will be listed upon notification of issuance, on any
national securities exchange or other organization on which the Preferred
Securities are then listed or traded, if any, (iv) such merger, consolidation,
conversion, amalgamation, replacement, conveyance, transfer or lease does not
cause the Preferred Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization, (v)
such merger, consolidation, conversion, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the Holders of the Preferred Securities (including any Successor
Securities) in any material respect, (vi) such successor entity has a purpose
substantially identical to that of the Trust, (vii) prior to such merger,
consolidation, conversion, amalgamation, replacement, conveyance, transfer or
lease, the Depositor has received an Opinion of Counsel to the effect that (a)
such merger, consolidation, conversion, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the Holders of the Preferred Securities (including any Successor
Securities) in any material respect, and (b)following such merger,
consolidation, conversion, amalgamation, replacement, conveyance, transfer or
lease, neither the Trust nor such successor entity will be required to register
as an investment company

                                       48

<PAGE>


under the 1940 Act and (viii) the Depositor owns all of the common securities
of such successor entity and guarantees the obligations of such successor
entity under the Successor Securities at least to the extent provided by the
Guarantee. Notwithstanding the foregoing, the Trust shall not, except with
the consent of Holders of 100% in Liquidation Amount of the Preferred
Securities, consolidate, amalgamate, convert into, merge with or into, or be
replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to any other entity or permit any other entity
to consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger, conversion, replacement, conveyance,
transfer or lease would cause the Trust or the successor entity to be
classified as other than a grantor trust for United States Federal income tax
purposes.

                                   Article X.

                            MISCELLANEOUS PROVISIONS

         Section 10.1      LIMITATION OF RIGHTS OF SECURITYHOLDERS.

         The death, dissolution, termination, bankruptcy or incapacity of any
Person having an interest, beneficial or otherwise, in Trust Securities shall
not operate to terminate this Trust Agreement, nor entitle the legal
successors, representatives or heirs of such Person or any Securityholder for
such Person, to claim an accounting, take any action or bring any proceeding
in any court for a partition or winding up of the arrangements contemplated
hereby, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

         Section 10.2      AMENDMENT.

                  (a) This Trust Agreement may be amended from time to time by
the Property Trustee, the Administrative Trustees and the Depositor, without the
consent of any Securityholders, (i) to cure any ambiguity, correct or supplement
any provision herein which may be inconsistent with any other provision herein,
or to make any other provisions with respect to matters or questions arising
under this Trust Agreement, which shall not be inconsistent with the other
provisions of this Trust Agreement, or (ii) to modify, eliminate or add to any
provisions of this Trust Agreement to such extent as shall be necessary to
ensure that the Trust will be classified for United States Federal income tax
purposes as a grantor trust at all times that any Trust Securities are
outstanding or to ensure that the Trust will not be required to register as an
investment company under the 1940 Act; provided, however, that in the case of
clause (i), such action shall not adversely affect in any material respect the
interests of any Securityholder, and any such amendments of this Trust Agreement
shall become effective when notice thereof is given to the Securityholders.

                  (b) Except as provided in Section 10.2(c) hereof, any
provision of this Trust Agreement may be amended by the Trustees and the
Depositor with (i) the consent of Trust Securityholders representing not less
than a majority (based upon Liquidation Amounts) of the Trust Securities then
Outstanding and (ii)receipt by the Trustees of an Opinion of Counsel to the
effect that such amendment or the exercise of any power granted to the Trustees
in accordance with such

                                     49

<PAGE>


amendment will not affect the Trust's status as a grantor trust for United
States Federal income tax purposes or the Trust's exemption from status of an
investment company under the 1940 Act.

                  (c) In addition to and notwithstanding any other provision in
this Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.3 or 6.6 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
paragraph (c) of this Section 10.2 may not be amended.

                  (d) Notwithstanding any other provisions of this Trust
Agreement, no Trustee shall enter into or consent to any amendment to this Trust
Agreement which would cause the Trust to fail or cease to qualify for the
exemption from status of an investment company under the 1940 Act or fail or
cease to be classified as a grantor trust for United States Federal income tax
purposes.

                  (e) Notwithstanding anything in this Trust Agreement to the
contrary, without the consent of the Depositor, this Trust Agreement may not be
amended in a manner which imposes any additional obligation on the Depositor.

                  (f) In the event that any amendment to this Trust Agreement is
made, the Administrative Trustees shall promptly provide to the Depositor a copy
of such amendment.

                  (g) Neither the Property Trustee nor the Delaware Trustee
shall be required to enter into any amendment to this Trust Agreement which
affects its own rights, duties or immunities under this Trust Agreement. The
Property Trustee shall be entitled to receive an Opinion of Counsel and an
Officers' Certificate stating that any amendment to this Trust Agreement is in
compliance with this Trust Agreement.

         Section 10.3      SEPARABILITY.

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

         Section 10.4      GOVERNING LAW.

         This Trust Agreement and the rights and obligations of each of the
Securityholders, the Trust and the Trustees with respect to this Trust Agreement
and the Trust Securities shall be construed in accordance with and governed by
the laws of the State of Delaware (without regard to conflict of laws
principles).

         Section 10.9      AGREEMENT NOT TO PETITION.

         Each of the Trustees and the Depositor agree for the benefit of the
Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Depositor takes action in violation of this Section 10.9, the
Property Trustee agrees, for the benefit of Securityholders, that at the expense
of the Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Trust
or the commencement of such action and raise the defense that the Depositor has
agreed in writing not to take such action and should be stopped and precluded
therefrom and such other defenses, if any, as counsel for the Trustee or the
Trust may assert. The provisions of this Section 10.9 shall survive the
termination of this Trust Agreement.

ACT.

         (a) This Trust Agreement is subject to the provisions of the Trust

the extent applicable, be governed by such provisions.

         (b) The Property Trustee shall be the only Trustee which is a trustee
for the purposes of the Trust Indenture Act.

         (c) If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Trust Agreement by any
of the provisions of the Trust Indenture Act, such required provision shall
control. If any provision of this Trust Agreement modifies or excludes any
provision of the Trust Indenture Act which may be so modified or excluded, the
latter provision shall be deemed to apply to this Trust Agreement as so modified

Certificate, duly endorsed for transfer as directed by the Issuer or the
