                             PHILLIPS 66 CAPITAL I
            ___% Trust Originated Preferred Securities(SM) ("TOPrS(SM)")
                (Liquidation Amount $25 per Preferred Security)
                  guaranteed to the extent set forth herein by

                           PHILLIPS PETROLEUM COMPANY
                              --------------------
         The ____%  Trust Originated Preferred Securities(SM) (the "Preferred
Securities") offered hereby represent preferred undivided beneficial interests
in the assets of Phillips 66 Capital I, a statutory business trust formed under
the laws of the State of Delaware ("Phillips Capital Trust" or the "Trust").
Phillips Petroleum Company, a Delaware corporation ("Phillips" or the
"Company"), will own all the common securities (the "Common Securities" and,
together with the Preferred Securities, the "Trust Securities") representing
undivided beneficial interests in the assets of Phillips Capital Trust.
Phillips Capital Trust exists for the sole purpose of issuing the Trust
Securities and investing the proceeds thereof in an equivalent amount of ____%
Junior Subordinated Deferrable Interest Debentures due 2036 (the "Subordinated
Debt Securities") of Phillips.  The Subordinated Debt Securities and the
Preferred Securities in respect of which this Prospectus Supplement is being
delivered shall be referred to herein as the "Offered Securities." The
Subordinated Debt Securities when issued will be unsecured obligations of
Phillips and will be subordinate and junior in right of payment to certain
other indebtedness of the Company, as described herein.  Upon an event of a
default under the Declaration (as defined herein), the holders of Preferred
Securities will have a preference over the holders of the Common Securities
with respect to payments in respect of distributions and payments upon
redemption, liquidation and otherwise.
                                                        (continued on next page)

         SEE "RISK FACTORS" BEGINNING  ON PAGE 5-6 OF THIS PROSPECTUS
SUPPLEMENT FOR CERTAIN INFORMATION RELEVANT TO AN INVESTMENT IN THE PREFERRED 
SECURITIES, INCLUDING THE PERIOD AND CIRCUMSTANCES DURING AND UNDER WHICH

RELATED UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF SUCH DEFERRAL.

         Application has been made to list the Preferred Securities on the New

trading of the Preferred Securities on the New York Stock Exchange is expected
to commence within a 30-day period after the initial delivery of the Preferred
Securities.  See "Underwriting."

(2)      Phillips Capital Trust and Phillips have agreed to indemnify the

         liabilities under the Securities Act of 1933, as amended.  See
         "Underwriting."
<PAGE>   4
(3)      In view of the fact that the proceeds of the sale of the Preferred
         Securities will be invested in the Subordinated Debt Securities,
         Phillips has agreed to pay to the Underwriters as compensation (the
         "Underwriters' Compensation") for their arranging the investment
         therein of such proceeds $_____ per Preferred Security (or $_______ in
         the aggregate); provided, that such compensation for sales of 10,000
         or more Preferred Securities to a single purchaser will be $__ per
         Preferred Security.  Therefore, to the extent of such sales, the
         actual amount of Underwriters' Compensation will be less than the
         aggregate amount specified in the preceding sentence.  See
         "Underwriting."
(4)      Expenses of the offering which are payable by Phillips are estimated
         to be $_______________.

         exercisable within 30 days of the date hereof, to purchase up to an 
         aggregate of _____ additional Preferred Securities at a price to 
         public less underwriting commission for the purpose of covering 
         over-allotments, if any.  If the Underwriters exercise such option in
         full, the total price to public, underwriting discounts and 
         commissions and proceeds to Phillips Capital Trust will be  
         $______________, $_______________ and $_______________, respectively. 
         See "Underwriting."

         The Preferred Securities offered hereby are offered severally by the
Underwriters, as specified herein, subject to receipt and acceptance by them
and subject to their right to reject any order in whole or in part.  It is
expected that delivery of the Preferred Securities will be made only in
book-entry form through the facilities of The Depository Trust Company, on or
about _________ __, 1996.

(continued from previous page)

         Holders of the Preferred Securities are entitled to receive cumulative
cash distributions at an annual rate of ___ percent of the liquidation amount
of $25 per Preferred Security, accruing from the date of original issuance and
payable quarterly in arrears on [March 31, June 30, September 30 and December
31] of each year, commencing [June 30,] 1996 ("distributions").  The payment of
distributions out of moneys held by Phillips Capital Trust and payments on
liquidation of Phillips Capital Trust or the redemption of Preferred
Securities, as set forth below, are guaranteed by Phillips (the "Guarantee") to
the extent described herein and under "Description of Preferred Securities
Guarantees" in the accompanying Prospectus.  The Guarantee covers payments of
distributions and other payments on the Preferred Securities only if and to the
extent that Phillips Capital Trust has funds available therefor which will not
be the case unless Phillips has made a payment of interest or principal or
other payments on the Subordinated Debt Securities held by Phillips Capital
Trust as its sole asset.  The Guarantee, when taken together with Phillips's
obligations under the Subordinated Debt Securities and the Indenture (as
defined below) and its obligations under the Declaration (as defined below),
including its liabilities to pay costs, expenses, debts and obligations of
Phillips Capital Trust (other than with respect to the Trust Securities),
provide a full and unconditional guarantee of amounts due on the Preferred
Securities.  See "Risk Factors -- Rights Under the Guarantee" herein.   The
obligations of Phillips under the Guarantee are subordinate and junior in right
of payment to all other liabilities of Phillips and pari passu with the most
senior preferred stock issued, from time to time, if any, by Phillips.  The
obligations of Phillips under the Subordinated Debt Securities are subordinate
and junior in right of payment to all present and future Senior Indebtedness
(as defined herein) of Phillips, which aggregated approximately $3.2 billion
at April 1, 1996, and rank pari passu with Phillips's other general unsecured
creditors.  The Subordinated Debt Securities purchased by the Trust may be
subsequently distributed pro rata to holders of the Preferred Securities and
Common Securities in connection with the dissolution of the Trust, upon the
occurrence of certain events.

         The distribution rate and the distribution payment date and other
payment dates for the Preferred Securities will correspond to the interest rate
and interest payment date and other payment dates on the Subordinated Debt
Securities, which will be the sole assets of the Trust.  As a result, if
principal or interest is not paid on the Subordinated Debt Securities, no
amounts will be paid on the Preferred Securities.  If Phillips does not make
principal or interest payments on the Subordinated Debt Securities, the Trust
will not have sufficient funds to make distributions on the Preferred
Securities, in which event, the Guarantee will not apply to such distributions
until the Trust has sufficient funds available therefor.

         So long as Phillips shall not be in default in the payment of interest
on the Subordinated Debt Securities, Phillips has the right to defer payments
of interest on the Subordinated Debt Securities by extending the interest
payment period on the Subordinated Debt Securities at any time for up to 20
consecutive quarters (each, an "Extension Period").  If interest payments are
so deferred, distributions will also be deferred.  During such Extension
Period, distributions will continue to accrue with interest thereon (to the
extent permitted by applicable law) at an annual rate of ___ percent per annum
compounded quarterly, and during any Extension Period, holders of Preferred
Securities will be required to include deferred interest income in their gross
income for United States federal income tax purposes in advance of receipt of
the cash distributions with respect to such deferred interest payments.  There
could be multiple Extension Periods of varying lengths throughout the term of
the Subordinated Debt Securities.  See "Description of the Subordinated Debt
Securities -- Option to Extend Interest Payment Period;" "Risk Factors --
Option to Extend Interest Payment Period" and "United States Federal Income
Taxation -- Original Issue Discount."

         The Subordinated Debt Securities are redeemable by Phillips, in whole
or in part, from time to time, on or after _____ __, ____, or at any time in
certain circumstances upon the occurrence of a Tax Event (as defined herein).
If Phillips redeems Subordinated Debt Securities, the Trust must redeem Trust
Securities on a pro rata basis having an aggregate liquidation amount equal to
the aggregate principal amount of the Subordinated Debt Securities so redeemed
at $25 per Preferred Security plus accrued and unpaid distributions thereon
(the "Redemption Price") to the date fixed for redemption.  See "Description of
the Preferred Securities -- Mandatory Redemption." The Preferred Securities
will be redeemed upon maturity of the Subordinated Debt Securities.  In
addition, upon the occurrence of a Tax Event arising from a change in law or a
change in legal interpretation regarding tax matters, unless the Subordinated
Debt Securities are redeemed in the limited circumstances described herein, the
Trust shall be dissolved, with the result that the Subordinated Debt Securities
will be





                                      S-3
<PAGE>   6
distributed to the holders of the Preferred Securities, on a pro rata basis, in
lieu of any cash distribution.  See "Description of the Preferred Securities --
Tax Event Redemption or Distribution." In certain circumstances, Phillips will
have the right to redeem the Subordinated Debt Securities, which would result
in the redemption by the Trust of Trust Securities in the same amount on a pro
rata basis.  If the Subordinated Debt Securities are distributed to the holders
of the Preferred Securities, Phillips will use its best efforts to have the
Subordinated Debt Securities listed on the New York Stock Exchange or on such
other exchange as the Preferred Securities are then listed.  See "Description
of the Preferred Securities -- Tax Event Redemption or Distribution" and
"Description of the Subordinated Debt Securities."

         In the event of the involuntary or voluntary dissolution, winding up
or termination of the Trust, the holders of the Preferred Securities will be
entitled to receive for each Preferred Security a liquidation amount of $25
plus accrued and unpaid distributions thereon (including interest thereon) to
the date of payment, unless, in connection with such dissolution, the
Subordinated Debt Securities are distributed to the holders of the Preferred
Securities.  See "Description of the Preferred Securities -- Liquidation
Distribution Upon Dissolution."

                             RECENT DEVELOPEMENTS

           In November 1995, the U.S. Court of Appeals for the Tenth Circuit 
affirmed the U.S. Tax Court's previous decisions related to Phillips' sales of
liquefied natural gas (LNG) from the Kenai, Alaska, facility to Japan. The Tax
Court's decisions supported the Company's position that more than 50 percent of
the income for the years 1975-1978 was from a foreign source. The Appellate
Court's decision became final on February 26, 1996, when the Internal Revenue
Service (IRS) elected not to petition the U.S. Supreme Court to review the
November 1995 decision. The favorable resolution of this issue will have a
positive effect on Phillips' first quarter 1996 net income of approximately
$570 million. In March 1996, Phillips received $209 million in cash refunds
from the IRS and expects to receive an estimated $165 million over the next few
years. The Company's net operating earnings in 1996 are also expected to benefit
by an estimated 20 to 25 cents a share, due to the lower effective tax rate on
Kenai LNG earnings and lower net interest charges on tax liabilities from prior
years.

                                  RISK FACTORS

         Prospective purchasers of Preferred Securities should carefully review
the information contained elsewhere in this Prospectus Supplement and in the
accompanying Prospectus and should particularly consider the following matters.

ABSENCE OF PRIOR PUBLIC MARKET

         Prior to this offering, there has been no public market for the
Preferred Securities.  Although application has been made to list the Preferred
Securities on the New York Stock Exchange, there can be no assurance that an
active public market will develop for the Preferred Securities or that, if such
market develops,the market price will equal or exceed the public offering price
set forth on the cover page of this Prospectus.  The public offering price for
the Preferred Securities has been determined through negotiations between the
Company and the Underwriters.  Prices for the Preferred Securities will be
determined in the marketplace and may be influenced by many factors, including
the liquidity of the market for the Preferred Securities, investor perceptions
of the Company and general industry and economic conditions.

RANKING OF SUBORDINATE OBLIGATIONS UNDER THE GUARANTEE AND SUBORDINATED DEBT
SECURITIES

         Phillips's obligations under the Guarantee are subordinate and junior
in right of payment to all liabilities of Phillips and pari passu with the most
senior preferred stock issued, from time to time, if any, by Phillips.  The
obligations of Phillips under the Subordinated Debt Securities are subordinate
and junior in right of payment to all present and future Senior Indebtedness of
Phillips and pari passu with obligations to or rights of Phillips's other
general unsecured creditors.  No payment of principal of (including redemption
payments, if any), premium, if any, or interest on the Subordinated Debt
Securities may be made if (i) any Senior Indebtedness of Phillips is not paid
when due and any applicable grace period with respect to such default has ended
with such default not having been cured or waived or ceasing to exist, or (ii)
the maturity of any Senior Indebtedness has been accelerated because of a
default.  As of April 1, 1996, Senior Indebtedness aggregated approximately
$3.2 billion.  There are no terms in the Preferred Securities, the Subordinated
Debt Securities or the Guarantee that limit Phillips's ability to incur
additional indebtedness, including indebtedness that ranks senior to the
Subordinated Debt Securities and the Guarantee.  See "Description of the
Preferred Securities Guarantees -- Status of the Preferred Securities
Guarantees" and "Description of the Subordinated Debt Securities" in the
accompanying Prospectus, and "Description of the Subordinated Debt Securities
- -- Subordination" herein.

RIGHTS UNDER THE GUARANTEE

         The Guarantee will be qualified as an indenture under the Trust
Indenture Act.  The Bank of New York will act as indenture trustee under the
Guarantee for the purposes of compliance with the provisions of the Trust
Indenture Act (the "Guarantee Trustee").  The Guarantee Trustee will hold the
Guarantee for the benefit of the holders of the Preferred Securities.

         The Guarantee guarantees to the holders of the Preferred Securities
the payment of (i) any accrued and unpaid distributions that are required to be
paid on the Preferred Securities, to the extent the Trust has funds available
therefor, (ii) the Redemption Price, including all accrued and unpaid
distributions with respect to Preferred Securities called for redemption by the
Trust, to the extent the Trust has funds available therefor, and (iii) 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 Preferred Securities or a redemption of all the Preferred
Securities), the lesser of (a) the aggregate of the liquidation amount and all
accrued and unpaid distributions on the Preferred Securities to the date of the
payment to the extent the Trust has funds available therefor or (b) the amount
of assets of the Trust remaining available for distribution to holders of the
Preferred Securities in liquidation of the Trust.  The holders of a majority in
liquidation amount of the Preferred Securities 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 trust or power conferred
upon the Guarantee Trustee under the Guarantee.  Notwithstanding the foregoing,
any holder of Preferred Securities may institute a legal proceeding directly
against





                                      S-6
<PAGE>   9
Phillips to enforce such holders' rights to receive payment under the Guarantee
without first instituting a legal proceeding against the Trust, the Guarantee
Trustee or any other person or entity.  If Phillips were to default on its
obligation to pay amounts payable on the Subordinated Debt Securities or
otherwise, the Trust would lack available funds for the payment of
distributions or amounts payable on redemption of the Preferred Securities or
otherwise, and, in such event, holders of the Preferred Securities would not be
able to rely upon the Guarantee for payment of such amounts.  Instead, holders
of the Preferred Securities would rely on the enforcement (1) by the
Institutional Trustee of its rights as registered holder of the Subordinated
Debt Securities against Phillips pursuant to the terms of the Subordinated Debt
Securities or (2) by such holder of its right against Phillips to enforce
payments on the Subordinated Debt Securities. See "Description of the Preferred
Securities Guarantees" and "Description of the Subordinated Debt Securities" in
the accompanying Prospectus.  The Declaration provides that each holder of
Preferred Securities, by acceptance thereof, agrees to the provisions of the
Guarantee, including the subordination provisions thereof, and the Indenture.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES

         If a Declaration Event of Default (as defined herein) occurs and is
continuing, then the holders of Preferred Securities would rely on the
enforcement by the Institutional Trustee of its rights as a holder of the
Subordinated Debt Securities against Phillips.  In addition, the holders of a
majority in liquidation amount of the Preferred Securities will have the right
to direct the time, method, and place of conducting any proceeding for any
remedy available to the Institutional Trustee or to direct the exercise of any
trust or power conferred upon the Institutional Trustee under the Declaration,
including the right to direct the Institutional Trustee to exercise the
remedies available to it as a holder of the Subordinated Debt Securities.  If
the Institutional Trustee fails to enforce its rights under the Subordinated
Debt Securities, a holder of Preferred Securities may institute a legal
proceeding directly against Phillips to enforce the Institutional Trustee's
rights under the Subordinated Debt Securities without first instituting any
legal proceeding against the Institutional Trustee or any other person or
entity.  Notwithstanding the foregoing, if a Declaration Event of Default has
occurred and is continuing and such event is attributable to the failure of
Phillips to pay interest or principal on the Subordinated Debt Securities on
the date such interest or principal is otherwise payable (or in the case of
redemption, on the redemption date), then a holder of Preferred Securities may
directly institute a proceeding for enforcement of payment to such holder of
the principal of or interest on the Subordinated Debt Securities having a
principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder (a "Direct Action") on or after the respective due
date specified in the Subordinated Debt Securities.  In connection with such
Direct Action, Phillips will be subrogated to the rights of such holder of
Preferred Securities under the Declaration to the extent of any payment made by
Phillips to such holder of Preferred Securities in such Direct Action.  The
holders of Preferred Securities will not be able to exercise directly any other
remedy available to the holders of the Subordinated Debt Securities.  See
"Description of the Preferred Securities  --  Declaration Events of Default."

OPTION TO EXTEND INTEREST PAYMENT PERIOD

         Phillips has the right under the Indenture (as such term is defined in
"Description of the Subordinated Debt Securities" herein) to defer payments of
interest on the Subordinated Debt Securities by extending the interest payment
period at any time, and from time to time, on the Subordinated Debt Securities.
As a consequence of such an extension, quarterly distributions on the Preferred
Securities would be deferred (but despite such deferral would continue to
accrue with interest thereon compounded quarterly) by the Trust during any such
extended interest payment period.  Such right to extend the interest payment
period for the Subordinated Debt Securities is limited to a period not
exceeding 20 consecutive quarters.  In the event that Phillips exercises this
right to defer interest payments, then (a) Phillips shall not declare or pay
dividends on, or make a distribution with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of its capital
stock (other than (i) purchases or acquisitions of shares of Phillips Common
Stock in connection with the satisfaction by Phillips of its obligations under
any employee benefit plans, (ii) as a result of a reclassification of Phillips
capital stock or the exchange or conversion of one class or series of
Phillips's capital stock for another class or series of Phillips capital stock
or (iii) the purchase of fractional interests in shares of Phillips's capital
stock pursuant to the conversion or exchange provisions of such Phillips
capital stock or the security being converted or exchanged, (b) Phillips shall
not make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities issued by Phillips that rank pari
passu with or junior to the Subordinated Debt Securities and (c) Phillips shall
not make any guarantee payments with respect to the foregoing (other than
pursuant to the Guarantee).





                                      S-7
<PAGE>   10
Prior to the termination of any such extension period, Phillips may further
extend the interest payment period; provided, that such Extension Period,
together with all such previous and further extensions thereof, may not exceed
20 consecutive quarters or extend beyond the maturity of the Subordinated Debt
Securities.  Upon the termination of any Extension Period and the payment of
all amounts then due, Phillips may commence a new Extension Period, subject to
the above requirements.  See "Description of the Preferred Securities --
Distributions" and "Description of the Subordinated Debt Securities -- Option
to Extend Interest Payment Period."

         Should Phillips exercise its right to defer payments of interest by
extending the interest payment period, each holder of Preferred Securities will
continue to accrue income (as original issue discount ("OID")) in respect of
the deferred interest allocable to its Preferred Securities for United States
federal income tax purposes, which will be allocated but not distributed, to
holders of record of Preferred Securities.  As a result, each such holder of
Preferred Securities will recognize income for United States federal income tax
purposes in advance of the receipt of cash and will not receive the cash from
Phillips Capital Trust related to such income if such holder disposes of its
Preferred Securities prior to the record date for the date on which
distributions of such amounts are made.  Phillips has no current intention of
exercising its right to defer payments of interest by extending the interest
payment period on the Subordinated Debt Securities.  However, should Phillips
determine to exercise such right in the future, the market price of the
Preferred Securities is likely to be affected.  A holder that disposes of its
Preferred Securities during an Extension Period, therefore, might not receive
the same return on its investment as a holder that continues to hold its
Preferred Securities.  In addition, as a result of the existence of Phillips's
right to defer interest payments, the market price of the Preferred Securities
(which represent an undivided beneficial interest in the Subordinated Debt
Securities) may be more volatile than other securities on which OID accrues
that do not have such rights.  See "United States Federal Income Taxation --
Original Issue Discount."

PROPOSED TAX LEGISLATION

                 On March 19, 1996, President Clinton proposed certain tax law
changes that would, among other things, generally deny corporate issuers a
deduction for interest in respect of certain debt obligations issued on or
after December 7, 1995 (the "Proposed Legislation") if such debt obligations
have a maximum term in excess of twenty years and are not shown as indebtedness
on the issuer's applicable consolidated balance sheet.  On March 29, 1996,
Senate Finance Committee Chairman William V. Roth, Jr. and House Ways and Means
Committee Chairman Bill Archer issued a joint statement (the "Joint Statement")
indicating their intent that certain legislative proposals initiated by the
Clinton administration, including the Proposed Legislation, that may be adopted
by either of the tax-writing committees of Congress would have an effective
date that is no earlier than the date of "appropriate Congressional action."
Based upon the Joint Statement, it is expected that if the Proposed Legislation
were to be enacted, such legislation would not apply to the Subordinated Debt
Securities.  There can be no assurances, however, that the effective date
guidance contained in the Joint Statement will be incorporated into the
Proposed Legislation, if enacted, or that other legislation enacted after the
date hereof will not otherwise adversely affect the ability of the Company to
deduct the interest payable on the Subordinated Debt Securities.  Accordingly,
there can be no assurance that a Tax Event will not occur.  See "Description of
the Preferred Securities -- Tax Event Redemption or Distribution."

TAX EVENT REDEMPTION OR DISTRIBUTION

         Upon the occurrence of a Tax Event, Phillips Capital Trust shall be
dissolved, except in the limited circumstance described below, with the result
that the Subordinated Debt Securities would be distributed to the holders of
the Trust Securities in connection with the liquidation of the Trust.  In
certain circumstances, Phillips shall have the right to redeem the Subordinated
Debt Securities, in whole or in part, in lieu of a distribution of the
Subordinated Debt Securities by the Trust; in which event the Trust will redeem
the Trust Securities on a pro rata basis to the same extent as the Subordinated
Debt Securities are redeemed by Phillips.  See "Description of the Preferred
Securities -- Tax Event Redemption or Distribution."

         Under current United States federal income tax law, a distribution of
Subordinated Debt Securities upon the dissolution of Phillips Capital Trust
would not be a taxable event to holders of the Preferred Securities.  Upon
occurrence of a Tax Event, however, a dissolution of Phillips Capital Trust in
which holders of the Preferred Securities receive cash would be a taxable event
to such holders.  See "United States Federal Income Taxation -- Receipt of
Subordinated Debt Securities or Cash Upon Liquidation of Phillips Capital
Trust."





                                      S-8
<PAGE>   11
         There can be no assurance as to the market prices for the Preferred
Securities or the Subordinated Debt Securities that may be distributed in
exchange for Preferred Securities if a dissolution or liquidation of the Trust
were to occur.  Accordingly, the Preferred Securities that an investor may
purchase, whether pursuant to the offer made hereby or in the secondary market,
or the Subordinated Debt Securities that a holder of Preferred Securities may
receive on dissolution and liquidation of the Trust, may trade at a discount to
the price that the investor paid to purchase the Preferred Securities offered
hereby.  Because holders of Preferred Securities may receive Subordinated Debt
Securities upon the occurrence of a Tax Event, prospective purchasers of
Preferred Securities are also making an investment decision with regard to the
Subordinated Debt Securities and should carefully review all the information
regarding the Subordinated Debt Securities contained herein and in the
accompanying Prospectus.  See "Description of the Preferred Securities -- Tax
Event Redemption or Distribution" and "Description of the Subordinated Debt
Securities -- General."

LIMITED VOTING RIGHTS

         Holders of Preferred Securities will have limited voting rights and
will not be entitled to vote to appoint, remove or replace, or to increase or
decrease the number of, Phillips Trustees, which voting rights are vested
exclusively in the holder of the Common Securities.  See "Description of
Preferred Securities -- Voting Rights."

TRADING PRICE

         The Preferred Securities may trade at a price that does not fully
reflect the value of accrued but unpaid interest with respect to the underlying
Subordinated Debt Securities.  A holder who disposes of his Preferred
Securities between record dates for payments of distributions thereon will be
required to include accrued but unpaid interest on the Subordinated Debt
Securities through the date of disposition in income as ordinary income (i.e.,
OID), and to add such amount to his adjusted tax basis in his pro rata share of
the underlying Subordinated Debt Securities deemed disposed of.  To the extent
the selling price is less than the holder's adjusted tax basis (which will
include, in the form of OID, all accrued but unpaid interest), a holder will
recognize a capital loss.  Subject to certain limited exceptions, capital
losses cannot be applied to offset ordinary income for United States federal
income tax purposes.  See "United States Federal Income Taxation -- Original
Issue Discount" and "Sales of Preferred Securities."

                                  THE COMPANY

                 The Company, incorporated in Delaware in 1917, is a fully
integrated oil company engaged in petroleum exploration and production on a
worldwide basis, petroleum refining and marketing, and natural gas gathering
and processing, principally in the United States.  Phillips also produces and
distributes chemicals worldwide.  Its principal executive offices are located
in the Phillips Building, Bartlesville, Oklahoma 74004 (telephone (918) 661-
6600)).


                             PHILLIPS CAPITAL TRUST

         Phillips Capital Trust is a statutory business trust formed under
Delaware law pursuant to (i) a declaration of trust, dated as of February 23,
1996, executed by Phillips, as sponsor (the "Sponsor"), and the trustees of
Phillips Capital Trust (the "Phillips Trustees") and (ii) the filing of a
certificate of trust with the Secretary of State of the State of Delaware on
February 23, 1996.  Such declaration will be amended and restated in its
entirety (as so amended and restated, the "Declaration") substantially in the
form filed as an exhibit to the Registration Statement of which this Prospectus
Supplement and the accompanying Prospectus form a part.  The Declaration will
be qualified as an indenture under the Trust Indenture Act of 1939, as amended
(the "Trust Indenture Act").  Upon issuance of the Preferred Securities, the
purchasers thereof will own all of the Preferred Securities.  See "Description
of the Preferred Securities -- Book-Entry Only Issuance -- The Depository Trust
Company." Phillips will directly or indirectly acquire Common Securities in an
aggregate liquidation amount equal to 3 percent of the total capital of Phillips
Capital Trust.  Phillips Capital Trust exists for the exclusive purposes of (i)
issuing the Trust Securities representing undivided beneficial interests in the
assets of the Trust, (ii) investing the gross proceeds of the Trust Securities
in the Subordinated Debt Securities and (iii) engaging in only those other
activities necessary or incidental thereto.

         Pursuant to the Declaration, the number of Phillips Trustees will
initially be five.  Three of the Phillips Trustees (the "Regular Trustees")
will be persons who are employees or officers of or who are affiliated with
Phillips.  The fourth trustee will be a financial institution that is
unaffiliated with Phillips, which trustee will serve as institutional trustee
under the Declaration and as indenture trustee for the purposes of compliance
with the provisions of the Trust Indenture Act (the "Institutional Trustee").
Initially, The Bank of New York, a New York banking corporation, will be the
Institutional Trustee until removed or replaced by the holder of the Common
Securities.  For the purpose of compliance with the provisions of the Trust
Indenture Act,  The Bank of New York will act as  trustee (the "Guarantee
Trustee") under the Guarantee and as Debt Trustee (as defined herein) under the
Indenture.  The fifth trustee will be an entity that maintains its principal
place of business in the state of Delaware (the "Delaware Trustee").
Initially, The Bank of New York (Delaware), an affiliate of the Institutional
Trustee, will act as Delaware Trustee.  See "Description of the Preferred
Securities Guarantees" in the accompanying Prospectus and "Description of the
Preferred Securities -- Voting Rights" herein.

         The Institutional Trustee will hold title to the Subordinated Debt
Securities for the benefit of the holders of the Trust Securities and the
Institutional Trustee will have the power to exercise all rights, powers and
privileges under the Indenture (as defined herein) as the holder of the
Subordinated Debt Securities.  In addition, the Institutional Trustee will
maintain exclusive control of a segregated non-interest bearing bank account
(the "Property Account") to hold all payments made in respect of the
Subordinated Debt Securities for the benefit of the holders of the Trust
Securities.  The Institutional Trustee will make payments of distributions and
payments on liquidation, redemption and otherwise to the holders of the Trust
Securities out of funds from the Property Account.  The Guarantee Trustee will
hold the Guarantee for the benefit of the holders of the Preferred Securities.
Phillips, as the direct or indirect holder of all the Common Securities, will
have the right to appoint, remove or replace any Phillips Trustee and to
increase or decrease the number of Phillips Trustees.  Phillips will pay all
fees and expenses related to Phillips Capital Trust and the offering of the
Trust Securities.  See "Description of the Subordinated Debt Securities --
Miscellaneous."

         The rights of the holders of the Preferred Securities, including
economic rights, rights to information and voting rights, are set forth in the
Declaration, the Delaware Business Trust Act (the "Trust Act") and the Trust
Indenture Act.  See "Description of the Preferred Securities."

                      RATIO OF EARNINGS TO FIXED CHARGES

         The following table sets forth the ratio of earnings to fixed charges
for the periods indicated:

</TABLE>


         For the purpose of computing the ratio of earnings to fixed charges,
earnings consist of income before income taxes, extraordinary items and
cumulative effect of changes in accounting principle, plus fixed charges
(excluding capitalized interest and the portion of the preferred dividend
requirements of a subsidiary not previously deducted from pretax income, but
including amortization of amounts previously capitalized), less equity in
undistributed earnings of companies owned less than 50 percent.  Fixed charges
consist of interest (including capitalized interest) on all indebtedness,
amortization of debt discount and expense, that portion of rental expense which
the Company believes to be representative of interest and the amounts accrued
to cover the preferred stock dividend requirements of a subsidiary.  A
statement setting forth the computation of the unaudited ratios of earnings to
fixed charges is filed as an exhibit to the Registration Statement of which
this Prospectus Supplement is a part.

                              ACCOUNTING TREATMENT

         The financial statements of Phillips Capital Trust will be reflected
in Phillips's consolidated financial statements with the Preferred Securities
shown as Company-Obligated Mandatorily Redeemable Preferred Securities of
Phillips Capital Trust, holding solely $ __________ principal amount of __%
Junior Subordinated Deferrable Interest Debentures due [          ] of
Phillips.  See "Capitalization."

                                USE OF PROCEEDS

         The Trust will use all proceeds received from the sale of the
Preferred Securities to purchase Subordinated Debt Securities from Phillips.
Phillips intends to add the net proceeds from the sale of the Subordinated Debt
Securities to its general funds, to be used for general corporate purposes,
including capital expenditures, repurchases of outstanding long-term debt
securities, investments in subsidiaries, working capital, repayment of
short-term commercial paper notes and other business opportunities.

                    DESCRIPTION OF THE PREFERRED SECURITIES

         The Preferred Securities will be issued pursuant to the terms of the
Declaration.  The Declaration will be qualified as an indenture under the Trust
Indenture Act.  The Institutional Trustee, The Bank of New York, will act as
indenture trustee for the Preferred Securities under the Declaration for
purposes of compliance with the provisions of the Trust Indenture Act.  The
terms of the Preferred Securities will include those stated in the Declaration
and those made part of the Declaration by the Trust Indenture Act.  The
following summary of the material terms and provisions of the Preferred
Securities does not purport to be complete and is subject to, and qualified in
its entirety by reference to, the Declaration, a copy of which is filed as an
exhibit to the Registration Statement of which this Prospectus Supplement is a
part, the Trust Act and the Trust Indenture Act.

GENERAL

         The Declaration authorizes the Regular Trustees to issue on behalf of
the Trust the Trust Securities, which represent undivided beneficial interests
in the assets of the Trust.  All of the Common Securities will be owned,
directly or indirectly, by Phillips.  The Common Securities rank pari passu,
and payments will be made thereon on a pro rata basis, with the Preferred
Securities, except that upon the occurrence and during the continuance of a
Declaration Event of Default, the rights of the holders of the Common
Securities to receive payment of periodic distributions and payments upon
liquidation, redemption and otherwise will be subordinated to the rights of the
holders of the Preferred Securities.  The Declaration does not permit the
issuance by the Trust of any securities





                                      S-12
<PAGE>   15
other than the Trust Securities or the incurrence of any indebtedness by the
Trust.  Pursuant to the Declaration, the Institutional Trustee will own the
Subordinated Debt Securities purchased by the Trust for the benefit of the
holders of the Trust Securities.  The payment of distributions out of money
held by the Trust, and payments upon redemption of the Preferred Securities or
liquidation of the Trust, are guaranteed by Phillips to the extent described
under "Description of the Preferred Securities Guarantees" in the accompanying
Prospectus.  The Guarantee will be held by [The Bank of New York], the
Guarantee Trustee, for the benefit of the holders of the Preferred Securities.
The Guarantee does not cover payment of distributions when the Trust does not
have sufficient available funds to pay such distributions.  In such event, the
remedy of a holder of Preferred Securities is to vote to direct the
Institutional Trustee to enforce the Institutional Trustee's rights under the
Subordinated Debt Securities except in the limited circumstances in which the
holder may take Direct Action.  See "Description of the Preferred Securities --
Voting Rights"  and "-- Declaration Events of Default."

DISTRIBUTIONS

         Distributions on the Preferred Securities will be fixed at a rate per
annum of ___ percent of the stated liquidation amount of $25 per Preferred 
Security. Distributions in arrears for more than one quarter will bear interest
thereon at the rate per annum of ____ percent thereof compounded quarterly. 
The term "distribution" as used herein includes any such interest payable
unless otherwise stated.  The amount of distributions payable for any period
will be computed on the basis of a 360-day year of twelve 30-day months.

          Distributions on the Preferred Securities will be cumulative, will
accrue from _______ __, 1996 and will be payable quarterly in arrears on [March
31, June 30, September 30 and December 31] of each year, commencing [June 30,]
1996, when, as and if available for payment, distributions will be made by the
Institutional Trustee, except as otherwise described below.

         Phillips has the right under the Indenture to defer payments of
interest on the Subordinated Debt Securities by extending the interest payment
period from time to time on the Subordinated Debt Securities, which, if
exercised, would defer quarterly distributions on the Preferred Securities
(though such distributions would continue to accrue with interest since
interest would continue to accrue on the Subordinated Debt Securities) during
any such extended interest payment period.  Such right to extend the interest
payment period for the Subordinated Debt Securities is limited to a period not
exceeding 20 consecutive quarters and such period may not extend beyond the
maturity of the Subordinated Debt Securities.  In the event that Phillips
exercises this right, then (a) Phillips shall not declare or pay dividends on,
make distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of shares of Phillips Common Stock in connection with
the satisfaction by Phillips of its obligations under any employee benefit
plans, (ii) as a result of a reclassification of Phillips capital stock or the
exchange or conversion of one class or series of Phillips's capital stock for
another class or series of Phillips capital stock or (iii) the purchase of
fractional interests in shares of Phillips's capital stock pursuant to the
conversion or exchange provisions of such Phillips capital stock or the
security being converted or exchanged) or make any guarantee payments with
respect to the foregoing) and (b) Phillips shall not make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities issued by Phillips that rank pari passu with or junior to such
Subordinated Debt Securities.  Prior to the termination of any such Extension
Period, Phillips may further extend the interest payment period; provided, that
such Extension Period, together with all such previous and further extensions
thereof, may not exceed 20 consecutive quarters or extend beyond the maturity
of the Subordinated Debt Securities.  Upon the termination of any Extension
Period and the payment of all amounts then due, Phillips may select a new
Extension Period, subject to the above requirements.  See "Description of the
Subordinated Debt Securities -- Interest" and "-- Option to Extend Interest
Payment Period." If distributions are deferred, the deferred distributions and
accrued interest thereon shall be paid to holders of record of the Preferred
Securities as they appear on the books and records of the Trust on the record
date next following the termination of such deferral period.

         Distributions on the Preferred Securities must be paid on the dates
payable to the extent that the Trust has funds available for the payment of
such distributions in the Property Account.  The Trust's funds available for
distribution to the holders of the Preferred Securities will be limited to
payments received from Phillips on the Subordinated Debt Securities.  See
"Description of the Subordinated Debt Securities." The payment of distributions





                                      S-13
<PAGE>   16
out of moneys held by the Trust is guaranteed by Phillips to the extent set
forth under "Description of the Preferred Securities Guarantees" in the
accompanying Prospectus.

         Distributions on the Preferred Securities will be payable to the
holders thereof as they appear on the books and records of the Trust on the
relevant record dates, which, as long as the Preferred Securities remain in
book-entry only form, will be one Business Day (as defined below) prior to the
relevant payment dates.  Such distributions will be paid through the
Institutional Trustee who will hold amounts received in respect of the
Subordinated Debt Securities in the Property Account for the benefit of the
holders of the Trust Securities.  Subject to any applicable laws and
regulations and the provisions of the Declaration, each such payment will be
made as described under "Book-Entry Only Issuance -- The Depository Trust
Company" below.  In the event that the Preferred Securities do not continue to
remain in book-entry only form, the Regular Trustee shall have the right to
select relevant record dates, which shall be more than one Business Day prior
to the relevant payment dates.  In the event that any date on which
distributions are to be made on the Preferred Securities is not a Business Day,
then payment of the distributions payable on such date will be made on the 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 such record date.  A "Business Day" shall mean any day other than
Saturday, Sunday or any other day on which banking institutions in New York
City (in the State of New York) are permitted or required by any applicable law
to close.

MANDATORY REDEMPTION

         The Subordinated Debt Securities will mature on _______ __, 2036 and
may be redeemed, in whole or in part, at any time on or after _______ __, 2001,
or at any time in certain circumstances upon the occurrence of a Tax Event.
See "Description of the Subordinated Debt Securities."  Upon the repayment of
the Subordinated Debt Securities, whether at maturity or upon redemption, the
proceeds from such repayment or payment shall simultaneously be applied to
redeem Trust Securities having an aggregate liquidation amount equal to the
aggregate principal amount of the Subordinated Debt Securities so repaid or
redeemed at the Redemption Price; provided, that holders of Trust Securities
shall be given not less than 30 nor more than 60 days notice of such
redemption.  See "Description of the Subordinated Debt Securities -- Optional
Redemption." In the event that fewer than all of the outstanding Preferred
Securities are to be redeemed, the Preferred Securities will be redeemed pro
rata as described under "Book-Entry Only Issuance-the Depository Trust Company"
below.

TAX EVENT REDEMPTION OR DISTRIBUTION

         "Tax Event" means that the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "Dissolution Tax Opinion") to the effect that, as a result of (a)
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 (b) any amendment to or
change in an interpretation or application of such laws or regulations by any
legislative body, court, governmental agency or regulatory authority (including
the enactment of any legislation and the publication of any judicial decision
or regulatory determination on or after such date), there is more than an
insubstantial risk that (i) the Trust would be subject to United States federal
income tax with respect to income accrued or received on the Subordinated Debt
Securities, (ii) interest payable to the Trust on the Subordinated Debt
Securities would not be deductible by Phillips for United States federal income
tax purposes or (iii) the Trust would be subject to more than a de minimis
amount of other taxes, duties or other governmental charges, which change or
amendment becomes effective on or after the date of this Prospectus Supplement.

         If, at any time, a Tax Event shall occur and be continuing, the Trust
shall, except in the limited circumstances described below, be dissolved with
the result that the Subordinated Debt Securities with an aggregate principal
amount equal to the aggregate stated liquidation amount of, with an interest
rate identical to the distribution rate of, and accrued and unpaid interest
equal to accrued and unpaid distributions on, the Trust Securities, would be
distributed to the holders of the Trust Securities in liquidation of such
holders' interests in the Trust on a pro rata basis within 90 days following
the occurrence of such Tax Event; provided, that such dissolution and
distribution shall be conditioned on (i) the Regular Trustees' receipt of an
opinion of nationally recognized independent tax counsel experienced in such
matters (a "No Recognition Opinion"), which opinion may rely on pub-





                                      S-14
<PAGE>   17
lished revenue rulings of the Internal Revenue Service, to the effect that the
holders of the Trust Securities will not recognize any gain or loss for United
States federal income tax purposes as a result of such dissolution and
distribution of Subordinated Debt Securities and (ii) Phillips being unable to
avoid such Tax Event within such 90 day period by taking some ministerial
action or pursuing some other reasonable measure that will have no adverse
effect on the Trust, Phillips or the holders of the Trust Securities.
Furthermore, if after receipt of a Dissolution Tax Opinion by the Regular
Trustees (i) Phillips has received an opinion (a "Redemption Tax Opinion") of
nationally recognized independent tax counsel experienced in such matters that,
as a result of a Tax Event, there is more than an insubstantial risk that
Phillips would be precluded from deducting the interest on the Subordinated
Debt Securities for United States federal income tax purposes, even after the
Subordinated Debt Securities were distributed to the holders of Trust
Securities in liquidation of such holders' interests in the Trust as described
above, or (ii) the Regular Trustees shall have been informed by such tax
counsel that it cannot deliver a No Recognition Opinion to the Trust, Phillips
shall have the right, upon not less than 30 nor more than 60 days notice, to
redeem the Subordinated Debt Securities, in whole or in part, for cash within
90 days following the occurrence of such Tax Event, and, following such
redemption, Trust Securities with an aggregate liquidation amount equal to the
aggregate principal amount of the Subordinated Debt Securities so redeemed
shall be redeemed by the Trust at the Redemption Price on a pro rata basis;
provided, however, that if at the time there is available to Phillips or the
Trust the opportunity to eliminate, within such 90 day period, the Tax Event by
taking some ministerial action, such as filing a form or making an election or
pursuing some other similar reasonable measure that has no adverse effect on
the Trust, Phillips or the holders of the Trust Securities, Phillips or the
Trust will pursue such measure in lieu of redemption.

         If the Subordinated Debt Securities are distributed to the holders of
the Preferred Securities, Phillips will use its best efforts to cause the
Subordinated Debt Securities to be listed on the New York Stock Exchange or on
such other exchange as the Preferred Securities are then listed.

         After the date for any distribution of Subordinated Debt Securities
upon dissolution of the Trust, (i) the Preferred Securities will no longer be
deemed to be outstanding, (ii) the Depositary (as defined herein) or its
nominee, as the record holder of the Preferred Securities, will receive a
registered global certificate or certificates representing the Subordinated
Debt Securities to be delivered upon such distribution, and (iii) any
certificates representing Preferred Securities not held by the Depositary or
its nominee will be deemed to represent Subordinated Debt Securities having an
aggregate principal amount equal to the aggregate stated liquidation amount of,
with an interest rate identical to the distribution rate of, and accrued and
unpaid interest equal to accrued and unpaid distributions on such Preferred
Securities until such certificates are presented to Phillips or its agent for
transfer or reissuance.

         There can be no assurance as to the market prices for either the
Preferred Securities or the Subordinated Debt Securities that may be
distributed in exchange for the Preferred Securities if a dissolution and
liquidation of the Trust were to occur.  Accordingly, the Preferred Securities
that an investor may purchase, whether pursuant to the offer made hereby or in
the secondary market, or the Subordinated Debt Securities that an investor may
receive if a dissolution and liquidation of the Trust were to occur, may trade
at a discount to the price that the investor paid to purchase the Preferred
Securities offered hereby.





                                      S-15
<PAGE>   18
REDEMPTION PROCEDURES

         The Trust may not redeem fewer than all of the outstanding Preferred
Securities unless all accrued and unpaid distributions have been paid on all
Preferred Securities for all quarterly distribution periods terminating on or
prior to the date of redemption.

         If the Trust gives a notice of redemption in respect of Preferred
Securities (which notice will be irrevocable), then, by 12:00 noon, New York
City time, on the redemption date, provided that Phillips has paid to the
Institutional Trustee a sufficient amount of cash in connection with the
related redemption or maturity of the Subordinated Debt Securities, the Trust
will irrevocably deposit with the Depositary funds sufficient to pay the
applicable Redemption Price and will give the Depositary irrevocable
instructions and authority to pay the Redemption Price to the holders of the
Preferred Securities.  See "Book-Entry Only Issuance -- The Depository Trust
Company." If notice of redemption shall have been given and funds deposited as
required, then, immediately prior to the close of business on the date of such
deposit, distributions will cease to accrue and all rights of holders of such
Preferred Securities so called for redemption will cease, except the right of
the holders of such Preferred Securities to receive the Redemption Price but
without interest on such Redemption Price.  In the event that any date fixed
for redemption of Preferred Securities 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 (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
the event that payment of the Redemption Price in respect of Preferred
Securities is improperly withheld or refused and not paid either by the Trust,
or by Phillips pursuant to the Guarantee, distributions on such Preferred
Securities will continue to accrue at the then applicable rate from the
original redemption date to the date of payment, in which case the actual
payment date will be considered the date fixed for redemption for purposes of
calculating the Redemption Price.

         In the event that fewer than all of the outstanding Preferred
Securities are to be redeemed, the Preferred Securities will be redeemed pro
rata as described below under "Book-Entry Only Issuance -- The Depository Trust
Company."

         Subject to the foregoing and applicable law (including, without
limitation, United States federal securities laws), Phillips 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

         In the event of any voluntary or involuntary liquidation, dissolution,
winding-up or termination of the Trust (each a "Liquidation"), the then holders
of the Preferred Securities will be entitled to receive out of the assets of
the Trust, after satisfaction of liabilities to creditors, distributions in an
amount equal to the aggregate of the stated liquidation amount of $25 per
Preferred Security plus accrued and unpaid distributions thereon to the date of
payment (the "Liquidation Distribution"), unless, in connection with such
Liquidation, Subordinated Debt Securities in an aggregate stated principal
amount equal to the aggregate stated liquidation amount of, with an interest
rate identical to the distribution rate of, and accrued and unpaid interest
equal to accrued and unpaid distributions on, the Preferred Securities have
been distributed on a pro rata basis to the holders of the Preferred
Securities.

         If, upon any such 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 the Preferred Securities shall be paid on a pro rata basis.
The holders of the Common Securities will be entitled to receive distributions
upon any such dissolution pro rata with the holders of the Preferred
Securities, except that if a Declaration Event of Default has occurred and is
continuing, the Preferred Securities shall have a preference over the Common
Securities with regard to such distributions.

         Pursuant to the Declaration, the Trust shall terminate (i) on February
23, 2051, the expiration of the term of the Trust, (ii) upon the bankruptcy of
Phillips, (iii) upon the filing of a certificate of dissolution or its
equivalent





                                      S-16
<PAGE>   19
with respect to Phillips, the filing of a certificate of cancellation with
respect to the Trust after obtaining the consent of the holders of at least a
majority in liquidation amount of the Trust Securities affected thereby voting
together as a single class to file such certificate of cancellation or the
revocation of the charter of Phillips and the expiration of 90 days after the
date of revocation without a reinstatement thereof, (iv) upon the distribution
of Subordinated Debt Securities upon the occurrence of a Tax Event, (v) upon
the entry of a decree of a judicial dissolution of Phillips or the Trust, or
(vi) upon the redemption of all the Trust Securities.

DECLARATION EVENTS OF DEFAULT

         An event of default under the Indenture (an "Indenture Event of
Default") constitutes an event of default under the Declaration with respect to
the Trust Securities (a "Declaration Event of Default"); provided, that
pursuant to the Declaration, the holder of the Common Securities will be deemed
to have waived any Declaration Event of Default with respect to the Common
Securities until all Declaration Events of Default with respect to the
Preferred Securities have been cured, waived or otherwise eliminated.  Until
such Declaration Events of Default with respect to the Preferred Securities
have been so cured, waived, or otherwise eliminated, the Institutional Trustee
will be deemed to be acting solely on behalf of the holders of the Preferred
Securities and only the holders of the Preferred Securities will have the right
to direct the Institutional Trustee with respect to certain matters under the
Declaration, and therefore the Indenture.  If the Institutional Trustee fails
to enforce its rights under the Subordinated Debt Securities after a holder of
Preferred Securities has made a written request, such holder of record of
Preferred Securities may institute a legal proceeding against Phillips to
enforce the Institutional Trustee's rights under the Subordinated Debt
Securities without first instituting any legal proceeding against the
Institutional Trustee or any other person or entity.  Notwithstanding the
foregoing, if a Declaration Event of Default has occurred and is continuing and
such event is attributable to the failure of Phillips to pay interest or
principal on the Subordinated Debt Securities on the date such interest or
principal is otherwise payable (or in the case of redemption, the redemption
date), then a holder of Preferred Securities may directly institute a
proceeding for enforcement of payment to such holder directly of the principal
of or interest on the Subordinated Debt Securities having a principal amount
equal to the aggregate liquidation amount of the Preferred Securities of such
holder on or after the respective due date specified in the Subordinated Debt
Securities.  In connection with such Direct Action, Phillips will be subrogated
to the rights of such holder of Preferred Securities under the Declaration to
the extent of any payment made by Phillips to such holder of Preferred
Securities in such Direct Action.  The holders of Preferred Securities will not
be able to exercise directly any other remedy available to the holders of the
Subordinated Debt Securities.

         Upon the occurrence of a Declaration Event of Default, the
Institutional Trustee as the sole holder of the Subordinated Debt Securities
will have the right under the Indenture to declare the principal of and
interest on the Subordinated Debt Securities to be immediately due and payable.
Phillips and the Trust are each required to file annually with the
Institutional Trustee an officer's certificate as to its compliance with all
conditions and covenants under the Declaration.

VOTING RIGHTS

         Except as described herein, under the Trust Act, the Trust Indenture
Act and under "Description of the Preferred Securities Guarantees --
Modification of the Preferred Securities Guarantees; Assignment" in the
accompanying Prospectus, and as otherwise required by law and the Declaration,
the holders of the Preferred Securities will have no voting rights.

         Subject to the requirement of the Institutional Trustee obtaining a
tax opinion in certain circumstances set forth in the last sentence of this
paragraph, the holders of a majority in aggregate liquidation amount of the
Preferred Securities, have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Institutional
Trustee, or direct the exercise of any trust or power conferred upon the
Institutional Trustee under the Declaration including the right to direct the
Institutional Trustee, as holder of the Subordinated Debt Securities, to (i)
exercise the remedies available to it under the Indenture as a holder of the
Subordinated Debt Securities, (ii) waive any past Indenture Event of Default
that is waivable under the Base Indenture (as defined herein), (iii) exercise
any right to rescind or annul a declaration that the principal of all the
Subordinated Debt Securities shall be due and payable or (iv) consent to any
amendment, modification or termination of the Indenture or the Subordinated
Debt Securities where such consent shall be required; provided,





                                      S-17
<PAGE>   20
however, that, where a consent or action under the Indenture would require the
consent or act of holders of more than a majority in principal amount of the
Subordinated Debt Securities (a "Super-Majority") affected thereby, only the
holders of at least such Super-Majority in aggregate liquidation amount of the
Preferred Securities may direct the Institutional Trustee to give such consent
or take such action.  If the Institutional Trustee fails to enforce its rights
under the Subordinated Debt Securities after a holder of record of Preferred
Securities has made a written request, such holder of record of Preferred
Securities may institute a legal proceeding directly against Phillips to
enforce the Institutional Trustee's rights under the Subordinated Debt
Securities without first instituting any legal proceeding against the
Institutional Trustee or any other person or entity.  Notwithstanding the
foregoing, if a Declaration Event of Default has occurred and is continuing and
such event is attributable to the failure of Phillips to pay interest or
principal on the Subordinated Debt Securities on the date such interest or
principal is otherwise payable (or in the case of redemption on the redemption
date), then a holder of Preferred Securities may directly institute a
proceeding for enforcement of payment to such holder of the principal of or
interest on the Subordinated Debt Securities having a principal amount equal to
the aggregate liquidation amount of the Preferred Securities of such holder on
or after the respective due date specified in the Subordinated Debt Securities.
The Institutional Trustee shall notify all holders of the Preferred Securities
of any notice of default received from the Debt Trustee with respect to the
Subordinated Debt Securities.  Such notice shall state that such Indenture
Event of Default also constitutes a Declaration Event of Default.  Except with
respect to directing the time, method and place of conducting a proceeding for
a remedy, the Institutional Trustee shall not take any of the actions described
in clauses (i), (ii) or (iii) above unless the Institutional Trustee has
obtained an opinion of tax counsel to the effect that, as a result of such
action, the Trust will not fail to be classified as a grantor trust for United
States federal income tax purposes.

         In the event the consent of the Institutional Trustee, as the holder
of the Subordinated Debt Securities, is required under the Indenture with
respect to any amendment, modification or termination of the Indenture, the
Institutional Trustee shall request the direction of the holders of the Trust
Securities with respect to such amendment, modification or termination and
shall vote with respect to such amendment, modification or termination as
directed by a majority in liquidation amount of the Trust Securities voting
together as a single class; provided, however, that where a consent under the
Indenture would require the consent of a Super-Majority, the Institutional
Trustee may only give such consent at the direction of the holders of at least
the proportion in liquidation amount of the Trust Securities which the relevant
Super-Majority represents of the aggregate principal amount of the Subordinated
Debt Securities outstanding.  The Institutional Trustee shall not take any such
action in accordance with the directions of the holders of the Trust Securities
unless the Institutional Trustee has obtained an opinion of tax counsel to the
effect that for the purposes of United States federal income tax the Trust will
not be classified as other than a grantor trust.

         A waiver of an Indenture Event of Default will constitute a waiver of
the corresponding Declaration Event of Default.

         Any required approval or direction of holders of Preferred Securities
may be given at a separate meeting of holders of Preferred Securities convened
for such purpose, at a meeting of all of the holders of Trust Securities or
pursuant to written consent.  The Regular Trustees will cause a notice of any
meeting at which holders of Preferred Securities are entitled to vote, or of
any matter upon which action by written consent of such holders is to be taken,
to be mailed to each holder of record of Preferred Securities.  Each such
notice will include a statement setting forth the following information: (i)
the date of such meeting or the date by which such action is to be taken; (ii)
a description of any resolution proposed for adoption at such meeting on which
such holders are entitled to vote or of such matter upon which written consent
is sought; and (iii) instructions for the delivery of proxies or consents.  No
vote or consent of the holders of Preferred Securities will be required for the
Trust to redeem and cancel Preferred Securities or distribute Subordinated Debt
Securities in accordance with the Declaration.

         Notwithstanding that holders of Preferred Securities are entitled to
vote or consent under any of the circumstances described above, any of the
Preferred Securities that are owned at such time by Phillips or any entity
directly or indirectly controlling or controlled by, or under direct or
indirect common control with, Phillips, shall not be entitled to vote or
consent and shall, for purposes of such vote or consent, be treated as if such
Preferred Securities were not outstanding.





                                      S-18
<PAGE>   21
         The procedures by which holders of Preferred Securities may exercise
their voting rights are described below.  See "-- Book-Entry Only Issuance --
The Depository Trust Company" below.

         Holders of the Preferred Securities will have no rights to appoint or
remove the Phillips Trustees, who may be appointed, removed or replaced solely
by Phillips as the indirect or direct holder of all of the Common Securities.

MODIFICATION OF THE DECLARATION

         The Declaration may be modified and amended if approved by the Regular
Trustees (and in certain circumstances the Institutional Trustee), provided
that, if any proposed amendment provides for, or the Regular Trustees otherwise
propose to effect, (i) any action that would adversely affect the powers,
preferences or special rights of the Trust Securities, whether by way of
amendment to the Declaration or otherwise or (ii) the dissolution, winding-up
or termination of the Trust other than pursuant to the terms of the
Declaration, then the holders of the Trust Securities voting together as a
single 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 at
least a majority in liquidation amount of the Trust Securities affected
thereby; provided, that, if any amendment or proposal referred to in clause (i)
above would adversely affect only the Preferred Securities or the Common
Securities, then only the affected 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 a majority in liquidation amount of such class of
Securities.

         Notwithstanding the foregoing, no amendment or modification may be
made to the Declaration if such amendment or modification would (i) cause the
Trust to be classified for purposes of United States federal income taxation as
other than a grantor trust, (ii) reduce or otherwise adversely affect the
powers of the Institutional Trustee or (iii) cause the Trust to be deemed an
"investment company" which is required to be registered under the Investment
Company Act of 1940, as amended (the "1940 Act").

MERGERS, CONSOLIDATIONS OR AMALGAMATIONS

         The Trust may not consolidate, amalgamate, 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 body, except as
described below.  The Trust may, with the consent of the Regular Trustees and
without the consent of the holders of the Trust Securities, the Institutional
Trustee or the Delaware Trustee consolidate, amalgamate, merge with or into, or
be replaced by a trust organized as such under the laws of any State of the
United States; provided, that (i) if the Trust is not the survivor such
successor entity either (x) expressly assumes all of the obligations of the
Trust under the Trust Securities or (y) substitutes for the Preferred
Securities other securities having substantially the same terms as the Trust
Securities (the "Successor Securities"), so long as the Successor Securities
rank the same as the Trust Securities rank with respect to distributions and
payments upon liquidation, redemption and otherwise, (ii) Phillips expressly
acknowledges a trustee of such successor entity possessing the same powers and
duties as the Institutional Trustee as the holder of the Subordinated Debt
Securities, (iii) 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, (iv) such merger,
consolidation, amalgamation or replacement does not cause the Preferred
Securities (including any Successor Securities) to be downgraded by any
nationally recognized statistical rating organization, (v) such merger,
consolidation, amalgamation or replacement does not adversely affect the
rights, preferences and privileges of the holders of the Trust Securities
(including any Successor Securities) in any material respect (other than with
respect to any dilution of the holders' interest in the new entity), (vi) such
successor entity has a purpose identical to that of the Trust, (vii) prior to
such merger, consolidation, amalgamation or replacement, Phillips has received
an opinion of a nationally recognized independent counsel to the Trust
experienced in such matters to the effect that, (A) such merger, consolidation,
amalgamation or replacement does not adversely affect the rights, preferences
and privileges of the holders of the Trust Securities (including any Successor
Securities) in any material respect (other than with respect to any dilution of
the holders' interest in the new entity), and (B) following such merger,
consolidation, amalgamation or replacement, neither the Trust nor such
successor entity will be required to register as an investment company under
the 1940 Act and (viii) Phillips guarantees the obligations of such successor
entity under the Successor Securities at least to the extent provided by the
Guarantee and the Common Securities Guarantee (as described in the accompanying
Prospectus).  Notwithstanding the foregoing, the Trust shall not, except with
the consent of holders of 100 percent in liquidation amount of the Trust





                                      S-19
<PAGE>   22
Securities, consolidate, amalgamate, merge with or into, or be replaced by any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it, if such consolidation, amalgamation, merger or
replacement would cause the Trust or the Successor Entity to be classified as
other than a grantor trust for United States federal income tax purposes.

BOOK-ENTRY ONLY ISSUANCE-THE DEPOSITORY TRUST COMPANY

         The Depository Trust Company ("DTC") will act as securities depositary
(the "Depositary") for the Preferred Securities.  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 Preferred Securities
certificates, representing the total aggregate number of Preferred Securities,
will be issued and will be deposited with DTC.

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

         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 (the "Exchange Act").  DTC holds securities
that its participants ("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 certain
other organizations.  DTC is owned by a number of its Participants and by the
New York Stock Exchange, the American Stock Exchange, Inc., and the National
Association of Securities Dealers, Inc.  Access to the DTC system is also
available to others, such as securities brokers and dealers, banks and trust
companies that clear transactions through or maintain a direct or indirect
custodial relationship with a Direct Participant either directly or indirectly
("Indirect Participants").  The rules applicable to DTC and its Participants
are on file with the Securities and Exchange Commission.

         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 actual purchaser
of each Preferred Security ("Beneficial Owner") 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 Direct
or Indirect Participants through which the Beneficial Owners purchased
Preferred Securities.  Transfers of ownership interests in the Preferred
Securities are to be accomplished by entries made on the books of 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 the Preferred
Securities.  DTC's records reflect only the identity of the Direct Participants
to whose accounts such 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 such nominee, as the case may be, will be considered
the sole owner or holder of the Preferred Securities represented thereby for
all purposes under the Declaration and the Preferred Securities.  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 Declaration.

         DTC has advised the Company 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





                                      S-20
<PAGE>   23
in respect of such portion of the aggregate liquidation amount of Preferred
Securities as to which such Participant or Participants has or have given such
direction.  However, if there is an Event of Default under the Preferred
Securities, DTC will exchange the Global Certificates for Certificated
Securities, which it will distribute to its Participants and which will be
legended as set forth under the heading "Notices to Investors."

         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.

         Redemption notices in respect of the 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 the 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 Preferred Securities.  Under its usual
procedures, DTC would mail an Omnibus Proxy to the 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 credited 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 such 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
such Participants and Indirect Participants and not of DTC, the Trust or the
Company, subject to any statutory or regulatory requirements as may be in
effect from time to time.  Payment of distributions to DTC is the
responsibility of the Trust, disbursement of such payments to Participants is
the responsibility of DTC, and disbursement of such payments to the Beneficial
Owners is the responsibility of Participants and Indirect Participants.

         Except as provided herein, a Beneficial Owner of an interest in a
Global Certificate will not be entitled to receive physical delivery of
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 such
procedures, and such procedures may be discontinued at any time.  Neither the
Company, the Issuer nor the Trustee 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 Trust.  Under such circumstances, in the event that a
successor securities depository is not obtained, Preferred Security
certificates are required to be printed and delivered.  Additionally, the Trust
(with the consent of the Company) may decide to discontinue use of the system
of book-entry transfers through DTC (or a successor depository).  In that
event, certificates for the Preferred Securities will be printed and delivered.
In each of the above circumstances, the Company 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.  Such laws
may impair the ability to transfer beneficial interests in the global Preferred
Securities as represented by a Global Certificate.

PAYMENT AND PAYING AGENCY

         Payments in respect of the Preferred Securities represented by the
Global Certificates shall be made to DTC, which shall credit the relevant
accounts at DTC on the applicable distribution dates or, in the case of
Certificated Securities, such payments shall be made by check mailed to the
address of the holder entitled thereto as such address shall appear on the
Register.   The Paying Agent shall initially be The Bank of New York.  The
Paying Agent shall be permitted to resign as Paying Agent upon 30 days' written
notice to the Issuer Trustees.





                                      S-21
<PAGE>   24
In the event that [          ] shall no longer be the Paying Agent, the Trustee
shall appoint a successor to act as Paying Agent (which shall be a bank or
trust company).

REGISTRAR, TRANSFER AGENT AND PAYING AGENT

         The Institutional Trustee will act as registrar, transfer agent and
paying agent for the Preferred Securities.

         Registration of transfers of Preferred Securities will be effected
without charge by or on behalf of the Trust, but upon payment (with the giving
of such indemnity as the Trust or the Company may require) in respect of any
tax or other government charges which may be imposed in relation to it.

         The Trust will not be required to register or cause to be registered
the transfer of Preferred Securities after such Preferred Securities have been
called for redemption.

INFORMATION CONCERNING THE INSTITUTIONAL TRUSTEE

         The Institutional Trustee, prior to the occurrence of a default with
respect to the Trust Securities and after the curing of any defaults that may
have occurred, undertakes to perform only such duties as are specifically set
forth in the 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.  Subject to such provisions, the Institutional Trustee is under no
obligation to exercise any of the powers vested in it by the Declaration at the
request of any holder of Preferred Securities, unless offered reasonable
indemnity by such holder against the costs, expenses and liabilities which
might be incurred thereby.  The holders of Preferred Securities will not be
required to offer such indemnity in the event such holders, by exercising their
voting rights, direct the Institutional Trustee to take any action it is
empowered to take under the Declaration following a Declaration Event of
Default.  The Institutional Trustee also serves as trustee under the Guarantee
and the Indenture.  [The Company and certain of its subsidiaries maintain
deposit accounts and conduct other banking transactions with the Institutional
Trustee in the ordinary course of their business.]

GOVERNING LAW

         The Declaration and the Preferred Securities will be governed by, and
construed in accordance with, the internal laws of the State of Delaware.

MISCELLANEOUS

         The Regular Trustees are authorized and directed to operate the Trust
in such a way so that the Trust will not be required to register as an
"investment company" under the 1940 Act or characterized as other than a
grantor trust for United States federal income tax purposes.  Phillips is
authorized and directed to conduct its affairs so that the Subordinated Debt
Securities will be treated as indebtedness of Phillips for United States
federal income tax purposes.  In this connection, Phillips and the Regular
Trustees are authorized to take any action, not inconsistent with applicable
law, the certificate of trust of the Trust or the certificate of incorporation
of Phillips, that each of Phillips and the Regular Trustees determine in their
discretion to be necessary or desirable to achieve such end, as long as such
action does not adversely affect the interests of the holders of the Preferred
Securities or vary the terms thereof.

         Holders of the Preferred Securities have no preemptive rights.


                          DESCRIPTION OF THE GUARANTEE

         Pursuant to the Guarantee, Phillips will irrevocably and
unconditionally agree, to the extent set forth therein, to pay in full to the
holders of the Preferred Securities issued by  the Trust, the Guarantee
Payments (as defined in the accompanying Prospectus) (except to the extent paid
by the Trust), as and when due, regardless of any defense, right of set-off or
counterclaim which  the Trust may have or assert.  The Company's obligation to
make a Guarantee Payment may be satisfied by direct payment of the required
amounts by the Company to





                                      S-22
<PAGE>   25
the holders of Preferred Securities or by causing  the Trust to pay such
amounts to such holders.  The Guarantee will be qualified as an indenture under
the Trust Indenture Act.  The Bank of New York will act as indenture trustee
under the Guarantee (the "Guarantee Trustee").  The terms of the Guarantee will
be those set forth in such Guarantee and those made part of such Guarantee by
the Trust Indenture Act. The Guarantee will be held by the Guarantee Trustee
for the benefit of the holders of the Preferred Securities.  A summary
description of the Guarantee appears in the accompanying Prospectus under the
caption "Description of the Preferred Securities Guarantees."


                DESCRIPTION OF THE SUBORDINATED DEBT SECURITIES

         Set forth below is a description of the specific terms of the
Subordinated Debt Securities in which the Trust will invest the proceeds from
the issuance and sale of the Trust Securities.  This description supplements the
description of the general terms and provisions of the Subordinated Debt
Securities set forth in the accompanying Prospectus under the caption
"Description of the Subordinated Debt Securities."  The following description
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, the description in the accompanying Prospectus and the
Indenture, dated as of ____________ __, 1996 (the "Base Indenture"), between
Phillips and The Bank of New York, as Trustee (the "Debt Trustee"), as
supplemented by a First Supplemental Indenture, dated as of __________ __, 1996
(the Base Indenture, as so supplemented, is hereinafter referred to as the
"Indenture"), the forms of which are filed as Exhibits to the Registration
Statement of which this Prospectus Supplement and the accompanying Prospectus
form a part. Certain capitalized terms used herein are defined in the Indenture.

         Under certain circumstances involving the dissolution of the Trust
following the occurrence of a Tax Event, Subordinated Debt Securities may be
distributed to the holders of the Trust Securities in liquidation of the Trust.
See "Description of the Preferred Securities -- Tax Event Redemption or
Distribution."

         If the Subordinated Debt Securities are distributed to the holders of
the Preferred Securities, Phillips will use its best efforts to have the
Subordinated Debt Securities listed on the New York Stock Exchange or on such
other national securities exchange or similar organization on which the
Preferred Securities are then listed or quoted.

GENERAL

         The Subordinated Debt Securities will be issued as unsecured debt
under the Indenture. The Subordinated Debt Securities will be limited in
aggregate principal amount to approximately $____________________, ($
million if the Underwriters' over-allotment option is exercised in full), such
amount being the sum of the aggregate stated liquidation of the Preferred
Securities and the Common Securities.

         The Subordinated Debt Securities are not subject to a sinking fund
provision. The entire principal amount of the Subordinated Debt Securities will
mature and become due and payable, together with any accrued and unpaid
interest thereon including Compound Interest (as defined herein) and Additional
Interest (as defined herein), if any, on ______________ ___, 2036.

         If Subordinated Debt Securities are distributed to holders of
Preferred Securities in liquidation of such holders' interests in the Trust,
such Subordinated Debt Securities will initially be issued as a Global Security
(as defined herein). As described herein, under certain limited circumstances,
Subordinated Debt Securities may be issued in certificated form in exchange for
a Global Security.  See "Book-Entry and Settlement" below.  In the event that
Subordinated Debt Securities are issued in certificated form, such Subordinated
Debt Securities will be in denominations of $25 and integral multiples thereof
and may be transferred or exchanged at the offices described below. Payments on
Subordinated Debt Securities issued as a Global Security will be made to DTC, a
successor depositary or, in the event that no depositary is used, to a Paying
Agent for the Subordinated Debt Securities.  In the event Subordinated Debt
Securities are issued in certificated form, principal and interest will be
payable, the transfer of the Subordinated Debt Securities will be registrable
and Subordinated Debt Securities will be exchangeable for Subordinated Debt
Securities of other denominations of a like aggregate principal amount at the
corporate trust office of the Institutional Trustee in New York, New York;
provided, that at the option of





                                      S-23
<PAGE>   26
Phillips payment of interest may be made at the option of Phillips by check
mailed to the address of the holder entitled thereto or by wire transfer to an
account appropriately designated by the holder entitled thereto.
Notwithstanding the foregoing, so long as the holder of any Subordinated Debt
Securities is the Institutional Trustee, the payment of principal and interest
on the Subordinated Debt Securities held by the Institutional Trustee will be
made at such place and to such account as may be designated by the
Institutional Trustee.

         The Indenture does not contain provisions that afford holders of the
Subordinated Debt Securities protection in the event of a highly leveraged
transaction or other similar transaction involving Phillips that may adversely
affect such holders.

SUBORDINATION

         The Indenture provides that the Subordinated Debt Securities are
subordinated and junior in right of payment to all Senior Indebtedness of
Phillips.  No payment of principal (including redemption and sinking fund
payments), premium, if any, or interest on the Subordinated Debt Securities may
be made (i) if any Senior Indebtedness of Phillips is not paid when due, (ii)
any applicable grace period with respect to such default has ended and such
default has not been cured or waived or ceased to exist, or (iii) if the
maturity of any Senior Indebtedness of Phillips has been accelerated because of
a default.  Upon any distribution of assets of Phillips to creditors upon any
dissolution, winding-up, liquidation or reorganization, whether voluntary or
involuntary, or in bankruptcy, insolvency, receivership or other proceedings,
all principal, premium, if any, and interest due or to become due on all Senior
Indebtedness of Phillips must be paid in full before the holders of
Subordinated Debt Securities are entitled to receive or retain any payment.
Upon satisfaction of all claims of all Senior Indebtedness then outstanding,
the rights of the holders of the Subordinated Debt Securities will be
subrogated to the rights of the holders of Indebtedness of Phillips to receive
payments or distributions applicable to Senior Indebtedness until all amounts
owing on the Subordinated Debt Securities are paid in full.

         The term "Senior Indebtedness" means, with respect to Phillips, (i)
the principal, premium, if any, and interest in respect of (A) indebtedness of
such obligor, for money borrowed and (B) indebtedness evidenced by securities,
debentures, bonds or other similar instruments issued by such obligor,
including, without limitation, in the case of Phillips, all obligations under
[list of outstanding Senior Instruments, if any], (ii) all capital lease
obligations of such obligor, (iii) all obligations of such obligor issued or
assumed as the deferred purchase price of property, all conditional sale
obligations of such obligor and all obligations of such obligor under any title
retention agreement (but excluding trade accounts payable arising in the
ordinary course of business), (iv) all obligations of such obligor for the
reimbursement on any letter of credit, banker's acceptance, security purchase
facility or similar credit transaction, (v) all obligations of the type
referred to in clauses (i) through (iv) above of other persons for the payment
of which such obligor is responsible or liable as obligor, guarantor or
otherwise and (vi) all obligations of the type referred to in clauses (i)
through (v) above of other persons secured by any lien on any property or asset
of such obligor (whether or not such obligation is assumed by such obligor),
except for (1) any such indebtedness that is by its terms subordinated to or
pari passu with the Subordinated Debt Securities and (2) any indebtedness
between or among such obligor or its affiliates, including all other debt
securities and guarantees in respect of those debt securities, issued to (a)
any other Phillips Trust or a trustee of such trust and (b) any other trust, or
a trustee of such trust, partnership or other entity affiliated with Phillips
that is a financing vehicle of Phillips (a "financing entity") in connection
with the issuance by such financial entity of Preferred Securities or other
securities that rank pari passu with, or junior to, the Preferred Securities.
Such Senior Indebtedness shall continue to be Senior Indebtedness and be
entitled to the benefits of the subordination provisions irrespective of any
amendment, modification or waiver of any term of such Senior Indebtedness.

         The Indenture does not limit the aggregate amount of Senior
Indebtedness that may be issued by Phillips.  As of April 1, 1996,
Senior Indebtedness of Phillips aggregated approximately $3.2 billion.

OPTIONAL REDEMPTION

         Phillips shall have the right to redeem the Subordinated Debt
Securities, in whole or in part, from time to time, on or after ____________
____, ____, or at any time in certain circumstances upon the occurrence of a
Tax Event as described under "Description of the Preferred Securities-Tax Event
Redemption or Distribution," upon not less than 30 nor more than 60 days
notice, at a redemption price equal to 100 percent of the principal amount to be





                                      S-24
<PAGE>   27
redeemed plus any accrued and unpaid interest, including Additional Interest,
if any, to the redemption date.  If a partial redemption of the Preferred
Securities resulting from a partial redemption of the Subordinated Debt
Securities would result in the delisting of the Preferred Securities, Phillips
may only redeem the Subordinated Debt Securities in whole.

INTEREST

         Each Subordinated Debt  Securities shall bear interest at the rate of
___ percent per annum from the original date of issuance, payable quarterly in 
arrears on [March 31, June 30, September 30 and December 31] of each year (each
an "Interest Payment Date"), commencing [June 30,] 1996, to the person in whose
name such Subordinated Debt Securities is registered, subject to certain
exceptions, at the close of business on the Business Day next preceding such
Interest Payment Date.  In the event the Subordinated Debt Securities shall not
continue to remain in book-entry only form, Phillips shall have the right to
select record dates, which shall be more than one Business Day prior to the
Interest Payment Date.

         The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months.  The amount of interest
payable for any period shorter than a full quarterly period for which interest
is computed, will be computed on the basis of the actual number of days elapsed
per 30-day month.  In the event that any date on which interest is payable on
the Subordinated Debt Securities is not a Business Day, then payment of the
interest 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 is in the next succeeding calendar
year, then such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on such date.

OPTION TO EXTEND INTEREST PAYMENT PERIOD

         Phillips shall have the right at any time, and from time to time,
during the term of the Subordinated Debt Securities to defer payments of
interest by extending the interest payment period for a period not exceeding 20
consecutive quarters, at the end of which Extension Period, Phillips shall pay
all interest then accrued and unpaid (including any Additional Interest, as
herein defined) together with interest thereon compounded quarterly at the rate
specified for the Subordinated Debt Securities to the extent permitted by
applicable law ("Compound Interest"); provided, that during any such Extension
Period, (a) Phillips shall not declare or pay dividends on, make any
distribution with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to any of its capital stock (other than (i)
purchases or acquisitions of shares of Phillips Common Stock in connection with
the satisfaction by Phillips of its obligations under any employee benefit
plans, (ii) as a result of a reclassification of Phillips capital stock or the
exchange or conversion of one class or series of Phillips's capital stock for
another class or series of Phillips capital stock or (iii) the purchase of
fractional interests in shares of Phillips's capital stock pursuant to the
conversion or exchange provisions of such Phillips capital stock or the
security being converted or exchanged) or make any guarantee payments with
respect to the foregoing) and (b) Phillips shall not make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities issued by Phillips that rank pari passu with or junior to the
Subordinated Debt Securities.  Prior to the termination of any such Extension
Period, Phillips may further defer payments of interest by extending the
interest payment period; provided, however, that, such Extension Period,
including all such previous and further extensions, may not exceed 20
consecutive quarters or beyond the maturity of the Subordinated Debt
Securities.  Upon the termination of any Extension Period and the payment of
all amounts then due, Phillips may commence a new Extension Period, subject to
the terms set forth in this section.  No interest during an Extension Period,
except at the end thereof, shall be due and payable.  Phillips has no present
intention of exercising its right to defer payments of interest by extending
the interest payment period on the Subordinated Debt Securities.  If the
Institutional Trustee shall be the sole holder of the Subordinated Debt
Securities, Phillips shall give the Regular Trustees and the Institutional
Trustee notice of its selection of such Extension Period one Business Day prior
to the earlier of (i) the date distributions on the Preferred Securities are
payable or (ii) the date the Regular Trustees are required to give notice to
the New York Stock Exchange (or other applicable self-regulatory organization)
or to holders of the Preferred Securities of the record date or the date such
distribution is payable.  The Regular Trustees shall give notice of Phillips's
selection of such Extension Period to the holders of the Preferred Securities.
If the Institutional Trustee shall not be the sole holder of the Subordinated
Debt Securities, Phillips shall give the holders of the Subordinated Debt
Securities notice of its selection of such Extension Period ten Business Days
prior to the earlier of (i) the





                                      S-25
<PAGE>   28
Interest Payment Date or (ii) the date upon which Phillips is required to give
notice to the New York Stock Exchange (or other applicable self-regulatory
organization) or to holders of the Subordinated Debt Securities of the record
or payment date of such related interest payment.

ADDITIONAL INTEREST

         If at any time the Trust shall be required to pay any taxes, duties,
assessments or governmental charges of whatever nature (other than withholding
taxes) imposed by the United States, or any other taxing authority, then, in
any such case, Phillips will pay as additional interest ("Additional Interest")
such additional amounts as shall be required so that the net amounts received
and retained by the Trust after paying any such taxes, duties, assessments or
other governmental charges will be not less than the amounts the Trust would
have received had no such taxes, duties, assessments or other governmental
charges been imposed.

PROPOSED TAX LEGISLATION

                 On March 19, 1996, President Clinton proposed the Proposed
Legislation which, among other things, would generally deny corporate issuers a
deduction for interest in respect of certain debt obligations issued on or
after December 7, 1995 if such debt obligations have a maximum term in excess
of twenty years and are not shown as indebtedness on the issuer's applicable
consolidated balance sheet.  On March 29, 1996, Senate Finance Committee
Chairman William V. Roth, Jr. and House Ways and Means Committee Chairman Bill
Archer issued the Joint Statement indicating their intent that certain
legislative proposals initiated by the Clinton administration, including the
Proposed Legislation, that may be adopted by either of the tax-writing
committees of Congress would have an effective date that is no earlier than the
date of "appropriate Congressional action."  Based upon the Joint Statement, it
is expected that if the Proposed Legislation were to be enacted, such
legislation would not apply to the Subordinated Debt Securities.  There can be
no assurances, however, that the effective date guidance contained in the Joint
Statement will be incorporated into the Proposed Legislation, if enacted, or
that other legislation enacted after the date hereof will not otherwise
adversely affect the ability of the Company to deduct the interest payable on
the Subordinated Debt Securities.  Accordingly, there can be no assurance that
a Tax Event will not occur.  See "-- Tax Event Redemption or Distribution."

INDENTURE EVENTS OF DEFAULT

         If any Indenture Event of Default shall occur and be continuing, the
Institutional Trustee, as the holder of the Subordinated Debt Securities, will
have the right to declare the principal of and the interest on the Subordinated
Debt Securities (including any Compound Interest and Additional Interest, if
any) and any other amounts payable under the Indenture to be forthwith due and
payable and to enforce its other rights as a creditor with respect to the
Subordinated Debt Securities.  See "Description of Subordinated Debt Securities
- -- Events of Default" in the accompanying Prospectus for a description of the
Events of Default.  An Indenture Event of Default also constitutes a
Declaration Event of Default.  The holders of Preferred Securities in certain
circumstances have the right to direct the Institutional Trustee to exercise
its rights as the holder of the Subordinated Debt Securities.  See "Description
of the Preferred Securities -- Declaration Events of Default" and "Voting
Rights."  Notwithstanding the foregoing, if an Event of Default has occurred
and is continuing and such event is attributable to the failure of Phillips to
pay interest or principal on the Subordinated Debt Securities on the date such
interest or principal is otherwise payable, Phillips acknowledges that then a
holder of Preferred Securities may institute a Direct Action for payment on or
after the respective due date specified in the Subordinated Debt Securities.
Notwithstanding any payments made to such holder of Preferred Securities by
Phillips in connection with a Direct Action, Phillips shall remain obligated to
pay the principal of or interest on the Subordinated Debt Securities held by
the Trust or the Institutional Trustee of the Trust, and Phillips shall be
subrogated to the rights of the holder of such Preferred Securities with
respect to payments on the Preferred Securities to the extent of any payments
made by the Company to such holder in any Direct Action.  The holders of
Preferred Securities will not be able to exercise directly any other remedy
available to the holders of the Subordinated Debt Securities.





                                      S-26
<PAGE>   29
BOOK-ENTRY AND SETTLEMENT

         If distributed to holders of Preferred Securities in connection with
the involuntary or voluntary dissolution, winding-up or liquidation of the
Trust as a result of the occurrence of a Tax Event, the Subordinated Debt
Securities will be issued in the form of one or more global certificates (each
a "Global Security") registered in the name of the depositary or its nominee.
Except under the limited circumstances described below, Subordinated Debt
Securities represented by the Global Security will not be exchangeable for, and
will not otherwise be issuable as, Subordinated Debt Securities in definitive
form.  The Global Securities described above may not be transferred except by
the depositary to a nominee of the depositary or by a nominee of the depositary
to the depositary or another nominee of the depositary or to a successor
depositary or its nominee.

         The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in definitive form.  Such
laws may impair the ability to transfer beneficial interests in such a Global
Security.

          Except as provided below, owners of beneficial interests in such a
Global Security will not be entitled to receive physical delivery of
Subordinated Debt Securities in definitive form and will not be considered the
holders (as defined in the Indenture) thereof for any purpose under the
Indenture, and no Global Security representing Subordinated Debt Securities
shall be exchangeable, except for another Global Security of like denomination
and tenor to be registered in the name of the Depositary or its nominee or to a
successor Depositary or its nominee.  Accordingly, each Beneficial Owner must
rely on the procedures of the Depositary or if such person is not a
Participant, on the procedures of the Participant through which such person
owns its interest to exercise any rights of a holder under the Indenture.

THE DEPOSITARY

         If Subordinated Debt Securities are distributed to holders of
Preferred Securities in liquidation of such holders' interests in the Trust,
DTC will act as securities depositary for the Subordinated Debt Securities.
For a description of DTC and the specific terms of the depositary arrangements,
see "Description of the Preferred Securities-Book-Entry Only Issuance-The
Depository Trust Company."  As of the date of this Prospectus Supplement, the
description therein of DTC's book-entry system and DTC's practices as they
relate to purchases, transfers, notices and payments with respect to the
Preferred Securities apply in all material respects to any debt obligations
represented by one or more Global Securities held by Phillips.  Phillips may
appoint a successor to DTC or any successor depositary in the event DTC or such
successor depositary is unable or unwilling to continue as a depositary for the
Global Securities.

         None of Phillips, the Trust, the Institutional Trustee, any paying
agent and any other agent of Phillips or the Debt Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Security
for such Subordinated Debt Securities or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

DISCONTINUANCE OF THE DEPOSITARY'S SERVICES

         A Global Security shall be exchangeable for Subordinated Debt
Securities registered in the names of persons other than the Depositary or its
nominee only if (i) the Depositary notifies Phillips that it is unwilling or
unable to continue as a depositary for such Global Security and no successor
depositary shall have been appointed, (ii) the Depositary, at any time, ceases
to be a clearing agency registered under the Exchange Act at which time the
Depositary is required to be so registered to act as such depositary and no
successor depositary shall have been appointed, (iii) Phillips, in its sole
discretion, determines that such Global Security shall be so exchangeable or
(iv) there shall have occurred an Event of Default with respect to such
Subordinated Debt Securities.  Any Global Security that is exchangeable
pursuant to the preceding sentence shall be exchangeable for Subordinated Debt
Securities registered in such names as the Depositary shall direct.  It is
expected that such instructions will be based upon directions received by the
Depositary from its Participants with respect to ownership of beneficial
interests in such Global Security.

GOVERNING LAW

         The Indenture and the Subordinated Debt Securities will be governed
by, and construed in accordance with, the internal laws of the State of New
York.

MISCELLANEOUS

         The Indenture will provide that Phillips will pay all fees and
expenses related to (i) the offering of the Trust Securities and the
Subordinated Debt Securities, (ii) the organization, maintenance and
dissolution of the Trust, (iii) the retention of the Phillips Trustees and (iv)
the enforcement by the Institutional Trustee of the rights of the holders of
the Preferred Securities.  The payment of such fees and expenses will be fully
and unconditionally guaranteed by Phillips.

         Phillips will have the right at all times to assign any of its
respective rights or obligations under the Indenture to a direct or indirect
wholly-owned subsidiary of Phillips; provided that, in the event of any such
assignment, Phillips will remain liable for all of their respective
obligations.  Subject to the foregoing, the Indenture will be binding upon and
inure to the benefit of the parties thereto and their respective successors and
assigns.  The Indenture provides that it may not otherwise be assigned by the
parties thereto.


                        EFFECT OF OBLIGATIONS UNDER THE
                 SUBORDINATED DEBT SECURITIES AND THE GUARANTEE

         As set forth in the Declaration, the sole purpose of the Trust is to
issue the Trust Securities evidencing undivided beneficial interests in the
assets of the Trust, and to invest the proceeds from such issuance and sale in
the Subordinated Debt Securities.

         As long as payments of interest and other payments are made when due
on the Subordinated Debt Securities, such payments will be sufficient to cover
distributions and payments due on the Trust Securities because of the following
factors: (i) the aggregate principal amount of Subordinated Debt Securities
will be equal to the sum of the aggregate stated liquidation amount of the
Trust Securities; (ii) the interest rate and the interest and other payment
dates on the Subordinated Debt Securities will match the distribution rate and
distribution and other payment dates for the Preferred Securities; (iii)
Phillips shall pay all, and the Trust shall not be obligated to pay, directly
or indirectly, all costs, expenses, debt, and obligations of the Trust (other
than with respect to the Trust Securities); and (iv) the Declaration further
provides that the Phillips Trustees shall not take or cause or permit the Trust
to, among other things, engage in any activity that is not consistent with the
purposes of the Trust.

         Payments of distributions (to the extent funds therefor are available)
and other payments due on the Preferred Securities (to the extent funds
therefor are available) are guaranteed by Phillips as and to the extent set
forth under "Description of the Preferred Securities Guarantees" in the
accompanying Prospectus.  If Phillips does not make interest payments on the
Subordinated Debt Securities purchased by the Trust, it is expected that the
Trust will not have sufficient funds to pay distributions on the Preferred
Securities.  The Guarantee does not apply to any payment of distributions
unless and until the Trust has sufficient funds for the payment of such
distributions.  The Guarantee covers the payment of distributions and other
payments on the Preferred Securities only if and to the extent that Phillips
has made a payment of interest or principal on the Subordinated Debt Securities
held by the Trust as its sole asset.  The Guarantee, when taken together with
Phillips's obligations under the Subordinated Debt Securities and the Indenture
and its obligations under the Declaration, including its obligations to pay
costs, expenses, debts and liabilities of the Trust (other than  with respect
to the Trust Securities), provide a full and unconditional guarantee of amounts
on the Preferred Securities.

         If Phillips fails to make interest or other payments on the
Subordinated Debt Securities when due (taking account of any Extension Period),
the Declaration provides a mechanism whereby the holders of the Preferred
Securities, using the procedures described in "Description of the Preferred
Securities -- Book Entry Only Issuance -- The Depository Trust Company" and "--
Voting Rights," may direct the Institutional Trustee to enforce its rights
under the Subordinated Debt Securities.  If the Institutional Trustee fails to
enforce its rights under the Sub-





                                      S-28
<PAGE>   31
ordinated Debt Securities, a holder of Preferred Securities may institute a
legal proceeding against Phillips to enforce the Institutional Trustee's rights
under the Subordinated Debt Securities without first instituting any legal
proceeding against the Institutional Trustee or any other person or entity.
Notwithstanding the foregoing, if a Declaration Event of Default has occurred
and is continuing and such event is attributable to the failure of Phillips to
pay interest or principal on the Subordinated Debt Securities on the date such
interest or principal is otherwise payable (or in the case of redemption on the
redemption date), then a holder of Preferred Securities may institute a Direct
Action for payment on or after the respective due date specified in the
Subordinated Debt Securities.  In connection with such Direct Action, Phillips
will be subrogated to the rights of such holder of Preferred Securities under
the Declaration to the extent of any payment made by Phillips to such holder of
Preferred Securities in such Direct Action.  Phillips, under the Guarantee,
acknowledges that the Guarantee Trustee shall enforce the Guarantee on behalf
of the holders of the Preferred Securities.  If Phillips fails to make payments
under the Guarantee, the Guarantee provides a mechanism whereby the holders of
the Preferred Securities may direct the Guarantee Trustee to enforce its rights
thereunder.  Any holder of Preferred Securities may institute a legal
proceeding directly against Phillips to enforce the Guarantee Trustee's rights
under the Guarantee without first instituting a legal proceeding against the
Trust, the Guarantee Trustee, or any other person or entity.

         Phillips and the Trust believe that the above mechanisms and
obligations, taken together, provide a full and unconditional guarantee by
Phillips of payments due on the Preferred Securities.  See "Description of the
Preferred Securities Guarantees -- General" in the accompanying Prospectus.


                     UNITED STATES FEDERAL INCOME TAXATION

GENERAL

         In the opinion of Skadden, Arps, Slate, Meagher & Flom, special tax
counsel to Phillips and the Trust, the following is a summary of certain of the
material United States federal income tax consequences of the purchase,
ownership and disposition of Preferred Securities.  Unless otherwise stated,
this summary deals only with Preferred Securities held as capital assets by
holders who purchase the Preferred Securities upon original issuance ("Initial
Holders").  It does not deal with special classes of holders such as banks,
thrifts, real estate investment trusts, regulated investment companies,
insurance companies, dealers in securities or currencies, tax-exempt investors,
or persons that will hold the Preferred Securities as a position in a
"straddle," as part of a "synthetic security" or "hedge," as part of a
"conversion transaction" or other integrated investment, or as other than a
capital asset.  This summary also does not address the tax consequences to
persons that have a functional currency other than the U.S. Dollar or the tax
consequences to shareholders, partners or beneficiaries of a holder of
Preferred Securities.  Further, it does not include any description of any
alternative minimum tax consequences or the tax laws of any state or local
government or of any foreign government that may be applicable to the Preferred
Securities.  This summary is based on the Internal Revenue Code of 1986, as
amended (the "Code"), Treasury regulations thereunder and administrative and
judicial interpretations thereof, as of the date hereof, all of which are
subject to change, possibly on a retroactive basis.

CLASSIFICATION OF THE SUBORDINATED DEBT SECURITIES

         In connection with the issuance of the Subordinated Debt Securities,
Skadden, Arps, Slate, Meagher & Flom, special tax counsel to Phillips and the
Trust,  will render its opinion generally to the effect that under then current
law and assuming full compliance with the terms of the Indenture (and certain
other documents), and based on certain facts and assumptions contained in such
opinion, the Subordinated Debt Securities will be classified for United States
federal income tax purposes as indebtedness of Phillips.

CLASSIFICATION OF THE TRUST

         In connection with the issuance of the Preferred Securities, Skadden,
Arps, Slate, Meagher & Flom, special tax counsel to Phillips and the Trust,
will render its opinion generally to the effect that, under then current law
and assuming full compliance with the terms of the Declaration and the
Indenture (and certain other documents), and based on certain facts and
assumptions contained in such opinion, the Trust will be classified for United
States federal income tax purposes as a grantor trust and not as an association
taxable as a corporation.





                                      S-29
<PAGE>   32
Accordingly, for United States federal income tax purposes, each holder of
Preferred Securities generally will be considered the owner of an undivided
interest in the Subordinated Debt Securities, and each holder will be required
to include in its gross income any OID accrued with respect to its allocable
share of those Subordinated Debt Securities.

ORIGINAL ISSUE DISCOUNT

         Because Phillips has the option, under the terms of the Subordinated
Debt Securities, to defer payments of interest by extending interest payment
periods for up to 20 quarters, all of the stated interest payments on the
Subordinated Debt Securities will be treated as "original issue discount."
Holders of debt instruments issued with OID must include that discount in
income on an economic accrual basis before the receipt of cash attributable to
the interest, regardless of their method of tax accounting.  Generally, all of
a holder's taxable interest income with respect to the Subordinated Debt
Securities will be accounted for as OID, and actual distributions of stated
interest will not be separately reported as taxable income.  The amount of OID
that accrues in any month will approximately equal the amount of the interest
that accrues on the Subordinated Debt Securities in that month at the stated
interest rate.  In the event that the interest payment period is extended,
holders will continue to accrue OID approximately equal to the amount of the
interest payment due at the end of the extended interest payment period on an
economic accrual basis over the length of the extended interest period.

         Because income on the Preferred Securities will constitute OID,
corporate holders of Preferred Securities will not be entitled to a
dividends-received deduction with respect to any income recognized with respect
to the Preferred Securities.

MARKET DISCOUNT AND BOND PREMIUM

         Holders of Preferred Securities other than Initial Holders may be
considered to have acquired their undivided interests in the Subordinated Debt
Securities with market discount or acquisition premium as such phrases are
defined for United States federal income tax purposes.  Such holders are
advised to consult their tax advisors as to the income tax consequences of the
acquisition, ownership and disposition of the Preferred Securities.

RECEIPT OF SUBORDINATED DEBT SECURITIES OR CASH UPON LIQUIDATION OF PHILLIPS
CAPITAL TRUST

         Under certain circumstances, as described under the caption
"Description of the Preferred Securities -- Tax Event Redemption or
Distribution," Subordinated Debt Securities may be distributed to holders in
exchange for the Preferred Securities and in liquidation of the Trust.  Under
current law, such a distribution, for United States federal income tax
purposes, would be treated as a non-taxable event to each holder, and each
holder would receive an aggregate tax basis in the Subordinated Debt Securities
equal to such holder's aggregate tax basis in its Preferred Securities.  A
holder's holding period in the Subordinated Debt Securities so received in
liquidation of the Trust would include the period during which the Preferred
Securities were held by such holder.  If, however, the related special event is
a Tax Event which results in the Trust being treated as an association taxable
as a corporation, the distribution would likely constitute a taxable event to
holders of the Preferred Securities.

         Under certain circumstances described herein (see "Description of the
Preferred Securities"), the Subordinated Debt Securities may be redeemed for
cash and the proceeds of such redemption distributed to holders in redemption
of their Preferred Securities.  Under current law, such a redemption would, for
United States federal income tax purposes, constitute a taxable disposition of
the redeemed Preferred Securities, and a holder could recognize gain or loss as
if it sold such redeemed Preferred Securities for cash.  See "United States
Federal Income Taxation -- Sales of Preferred Securities."

SALES OF PREFERRED SECURITIES

         A holder that sells Preferred Securities will recognize gain or loss
equal to the difference between its adjusted tax basis in the Preferred
Securities and the amount realized on the sale of such Preferred Securities.  A
holder's adjusted tax basis in the Preferred Securities generally will be its
initial purchase price increased by OID previously includable in such holder's
gross income to the date of disposition and decreased by payments received





                                      S-30
<PAGE>   33
on the Preferred Securities.  Such gain or loss generally will be a capital
gain or loss and generally will be a long-term capital gain or loss if the
Preferred Securities have been held for more than one year.

         The Preferred Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest with respect to the underlying
Subordinated Debt Securities.  A holder who disposes of his Preferred
Securities between record dates for payments of distributions thereon will be
required to include accrued but unpaid interest on the Subordinated Debt
Securities through the date of disposition in income as ordinary income, and to
add such amount to his adjusted tax basis in his pro rata share of the
underlying Subordinated Debt Securities deemed disposed of.  To the extent the
selling price is less than the holder's adjusted tax basis (which will include,
in the form of OID, all accrued but unpaid interest) a holder will recognize a
capital loss.  Subject to certain limited exceptions, capital losses cannot be
applied to offset ordinary income for United States federal income tax
purposes.

UNITED STATES ALIEN HOLDERS

         For purposes of this discussion, a "United States Alien Holder" is any
corporation, individual, partnership, estate or trust that is, as to the United
States, a foreign corporation, a non-resident alien individual, a foreign
partnership, or a non-resident fiduciary of a foreign estate or trust.

         Under present United States federal income tax law: (i) payments by
the Trust or any of its paying agents to any holder of a Preferred Security who
or which is a United States Alien Holder will not be subject to United States
federal withholding tax; provided that, (a) the beneficial owner of the
Preferred Security does not actually or constructively own 10% or more of the
total combined voting power of all classes of stock of Phillips entitled to
vote, (b) the beneficial owner of the Preferred Security is not a controlled
foreign corporation that is related to Phillips through stock ownership, and
(c) either (A) the beneficial owner of the Preferred Security certifies to the
Trust or its agent, under penalties of perjury, that it is not a United States
holder and provides its name and address or (B) a securities clearing
organization, bank or other financial institution that holds customers'
securities in the ordinary course of its trade or business (a "Financial
Institution"), and holds the Preferred Security in such capacity, that
certifies to the Trust or its agent, under penalties of perjury, that such
statement has been received from the beneficial owner by it or by a Financial
Institution between it and the beneficial owner and furnishes the Trust or its
agent with a copy thereof; and (ii) a United States Alien Holder of a Preferred
Security will not be subject to United States federal withholding tax on any
gain realized upon the sale or other disposition of a Preferred Security.

PROPOSED TAX LEGISLATION

         On March 19, 1996, President Clinton proposed the Proposed Legislation
which, among other things, would generally deny corporate issuers a deduction
for interest in respect of certain debt obligations issued on or after December
7, 1995, if such debt obligations have a maximum term in excess of twenty years
and are not shown as indebtedness on the issuer's applicable consolidated
balance sheet.  On March 29, 1996, Senate Finance Committee Chairman William V.
Roth, Jr. and House Ways and Means Committee Chairman Bill Archer issued the
Joint Statement indicating their intent that certain legislative proposals
initiated by the Clinton administration, including the Proposed Legislation,
that may be adopted by either of the tax-writing committees of Congress would
have an effective date that is no earlier than the date of "appropriate
Congressional action."  Based upon the Joint Statement, it is expected that if
the Proposed Legislation were to be enacted, such legislation would not apply
to the Subordinated Debt Securities.  There can be no assurances, however, that
the effective date guidance contained in the Joint Statement will be
incorporated into the Proposed Legislation, if enacted, or that other
legislation enacted after the date hereof will not otherwise adversely affect
the ability of the Company to deduct the interest payable on the Subordinated
Debt Securities.  Accordingly, there can be no assurance that a Tax Event will
not occur.  See "Description of the Preferred Securities -- Tax Event
Redemption or Distribution."

INFORMATION REPORTING TO HOLDERS

         Generally, income on the Preferred Securities will be reported to
holders on Forms 1099, which forms should be mailed to holders of Preferred
Securities by January 31 following each calendar year.

tax, provided the required information is provided to the Service.

THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR
GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S
PARTICULAR SITUATION.  HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT

                                  UNDERWRITING


         Subject to the terms and conditions set forth in an underwriting
agreement (the "Underwriting Agreement"), Phillips Capital Trust has agreed to
sell to each of the Underwriters named below, and each of the Underwriters, for
whom [                                                ] is acting as
representative (the "Representative"), has severally agreed to purchase the
number of Preferred Securities set forth opposite its name below.  In the
Underwriting Agreement, the several Underwriters have agreed, subject to the
terms and conditions set forth therein, to purchase all the Preferred
Securities offered hereby if any of the Preferred Securities are purchased.  In
the event of default by an Underwriter, the Underwriting Agreement provides
that, in certain circumstances, the purchase commitments of the nondefaulting
Underwriters may be increased or the Underwriting Agreement may be terminated.

</TABLE>


         The Underwriters propose to offer the Preferred Securities, in part,
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus Supplement, and, in part, to certain securities
dealers at such price less a concession of $.   per Preferred Security.  The
Underwriters may allow, and such dealers may reallow, a concession not in
excess of $.   per Preferred Security to certain brokers and dealers.  After
the Preferred Securities are released for sale to the public, the offering
price and other selling terms may from time to time be varied by the
Representative.

         In view of the fact that the proceeds of the sale of the Preferred
Securities will ultimately be used to purchase the Subordinated Debt Securities
of Phillips, the Underwriting Agreement provides that Phillips will pay as
compensation ("Underwriters' Compensation") to the Underwriters' arranging the
investment therein of such proceeds, an amount in New York Clearing House (same
day) funds of $.     per Preferred Security (or $          in the aggregate)
for the accounts of the several Underwriters; provided that, such compensation
for sales of 10,000 or more Preferred Securities to any single purchaser will
be $.    per Preferred Security.  Therefore, to the extent of such sales, the
actual amount of Underwriters Compensation will be less than the aggregate
amount specified in the preceding sentence.

         During a period of 30 days from the date of the Prospectus Supplement,
neither Phillips Capital Trust nor Phillips will, without the prior written
consent of the Underwriters, directly or indirectly, sell, offer to sell, grant
any option for sale of, or otherwise dispose of, any Preferred Securities, any
security convertible into or exchangeable into or exercisable for Preferred
Securities or Subordinated Debt Securities or any debt securities substantially
similar to the Subordinated Debt Securities or equity securities substantially
similar to the Preferred Securities (except for the Subordinated Debt
Securities and the Preferred Securities offered hereby).

         The Preferred Securities have been approved for listing on the New
York Stock Exchange.  Trading of the Preferred Securities on the New York Stock
Exchange is expected to commence within a 30-day period after the initial
delivery of the Preferred Securities.  The Representative has advised Phillips
Capital Trust that it intends to make a market in the Preferred Securities
prior to the commencement of trading on the New York Stock Exchange.  The
Underwriters will have no obligation to make a market in the Preferred
Securities, however, and may cease market making activities, if commenced, at
any time.

<PAGE>   36
         Prior to this offering there has been no public market for the
Preferred Securities.  In order to meet one of the requirements for listing the
Preferred Securities on the New York Stock Exchange, the Underwriters will
undertake to sell lots of 100 or more Preferred Securities to a minimum of 400
beneficial holders.

         Phillips Capital Trust and Phillips have agreed to indemnify the
Underwriters against, or contribute to payments that the Underwriters may be
required to make in respect of, certain liabilities, including liabilities
under the Securities Act of 1933, as amended.

         Certain of the Underwriters engage in transactions with, and, from
time to time, have performed services for, Phillips and its subsidiaries in the
ordinary course of business.


                                 LEGAL MATTERS

         Certain matters of Delaware law relating to the validity of the
Preferred Securities will be passed upon on behalf of the Trust by Skadden,
Arps, Slate, Meagher & Flom, special Delaware counsel to the Trust.  The
validity of the Subordinated Debt Securities and the Guarantee and certain
matters relating thereto and certain United States federal income taxation
matters and will be passed upon for Phillips and the Trust by Skadden, Arps,
Slate, Meagher & Flom.  Certain United States federal income taxation matters
will be passed upon for Phillips by Dale J. Billam, Esq. and the Trust by

     Phillips Petroleum Company ("Phillips" or the "Company"), a Delaware
corporation, may from time to time offer its subordinated debentures, notes or
other evidence of indebtedness (the "Subordinated Debt Securities") in one or
more series and in amounts, at prices and on terms to be determined at the time
of the offering.  The Subordinated Debt Securities when issued will be unsecured
obligations of the Company.  The Company's obligations under the Subordinated
Debt Securities will be subordinate and junior in right of payment to certain
other indebtedness, as may be described in an accompanying Prospectus
Supplement (the "Prospectus Supplement") and in an aggregate amount to be set
forth as of the most recent practicable date in such Prospectus Supplement.
    

     Phillips 66 Capital I, Phillips 66 Capital II, Phillips 66 Capital III and
Phillips 66 Capital IV (each, a "Phillips Capital Trust"), each a statutory
business trust formed under the laws of the State of Delaware, may offer, from
time to time, preferred securities, representing undivided beneficial interests
in the assets of the respective Phillips Capital Trust ("Preferred Securities").
The payment of periodic cash distributions ("distributions") with respect to
Preferred Securities of each of the Phillips Capital Trusts out of moneys held
by each of the Phillips Capital Trusts, and payment on liquidation, redemption
or otherwise with respect to such Preferred Securities, will be guaranteed by
Phillips to the extent described herein (each a "Preferred Securities
Guarantee").  See "Description of the Preferred Securities Guarantees" below.
Phillips' obligations under the Preferred Securities Guarantees are subordinate
and junior in right of payment to all other liabilities of Phillips and rank
pari passu with the most senior preferred stock, if any, issued from time to
time by Phillips. Subordinated Debt Securities may be issued and sold from time
to time in one or more series to a Phillips Capital Trust, or a trustee of such
Phillips Capital Trust, in connection with the investment of the proceeds from
the offering of Preferred Securities and Common Securities (as defined herein,
together the "Trust Securities") of such Phillips Capital Trust.  The
Subordinated Debt Securities purchased by a Phillips Capital Trust may be
subsequently distributed pro rata to holders of Preferred Securities and Common
Securities in connection with the dissolution of such Phillips Capital Trust
upon the occurrence of certain events as may be described in an accompanying
Prospectus Supplement.  The Subordinated Debt Securities and the Preferred
Securities and the related Preferred Securities Guarantees are sometimes
collectively referred to hereafter as the "Offered Securities."

     Specific terms of the Subordinated Debt Securities of any series or the
Preferred Securities of any Phillips Capital Trust in respect of which this
prospectus (the "Prospectus") is being delivered will be set forth in a
Prospectus Supplement with respect to such securities, which will describe,
without limitation and where applicable, the following:  (i) in the case of
Subordinated Debt Securities, the specific designation, aggregate principal
amount, denomination, maturity, premium, if any, any exchange, conversion,
redemption or sinking fund provisions, if any, interest rate (which may be fixed
or variable), if any, the time and method of calculating interest payments, if
any, dates on which premium, if any, and interest, if any, will be payable, the
right of Phillips, if any, to defer payment of interest on the Subordinated Debt
Securities and the maximum length of such deferral period, the initial public
offering price, subordination terms, and any listing on a securities exchange
and other specific terms of the offering; and (ii) in the case of Preferred
Securities, the designation, number of securities, liquidation preference per
security, initial public offering price, any listing on a securities exchange,
distribution rate (or method of calculation thereof),
<PAGE>   38
dates on which distributions shall be payable and dates from which distributions
shall accrue, any voting rights, terms for any conversion or exchange into other
securities, any redemption, exchange or sinking fund provisions, any other
rights, preferences, privileges, limitations or restrictions relating to the
Preferred Securities and the terms upon which the proceeds of the sale of the
Preferred Securities shall be used to purchase a specific series of Subordinated
Debt Securities of Phillips.

     The Offered Securities may be offered in amounts, at prices and on terms to
be determined at the time of offering; provided, however, that the aggregate
initial public offering price of all Offered Securities shall not exceed
$750,000,000.  The Prospectus Supplement relating to any series of Offered
Securities will contain information concerning certain United States federal
income tax considerations, if applicable to the Offered Securities.

     Phillips and/or each of the Phillips Capital Trusts may sell the Offered
Securities directly, through agents designated from time to time, or through
underwriters or dealers.  See "Plan of Distribution" below.  If any agents of
Phillips and/or any Phillips Capital Trust or any underwriters or dealers are
involved in the sale of the Offered Securities, the names of such agents,
underwriters or dealers and any applicable commissions and discounts will be set
forth in any related Prospectus Supplement.

     This Prospectus may not be used to consummate sales of securities unless
accompanied by a Prospectus Supplement.

           THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY
              THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE
                SECURITIES COMMISSION NOR HAS THE SECURITIES AND

                             AVAILABLE INFORMATION

     This Prospectus constitutes a part of a combined Registration Statement on
Form S-3 (together with all amendments and exhibits thereto, the "Registration
Statement") filed by Phillips and the Phillips Capital Trusts with the
Securities and Exchange Commission (the "SEC") under the Securities Act of 1933,
as amended (the "Securities Act"), with respect to the Offered Securities.  This
Prospectus does not contain all of the information set forth in such
Registration Statement, certain parts of which are omitted in accordance with
the rules and regulations of the SEC.  Reference is made to such Registration
Statement and to the exhibits relating thereto for further information with
respect to the Company, the Phillips Capital Trusts and the Offered Securities.
Any statements contained herein concerning the provisions of any document filed
as an exhibit to the Registration Statement or otherwise filed with the SEC or
incorporated by reference herein are not necessarily complete, and, in each
instance, reference is made to the copy of such document so filed for a more
complete description of the matter involved.  Each such statement is qualified
in its entirety by such reference.

     Phillips is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
therewith files reports, proxy statements and other information with the SEC.
Reports, proxy statements and other information concerning Phillips can be
inspected and copied at prescribed rates at the SEC's Public Reference Room,
Judiciary Plaza, 450 Fifth Street, Northwest, Washington, D.C. 20549, as well as
the following Regional Offices of the SEC:  7 World Trade Center, New York, New
York 10048; and Northwestern Atrium Center, 500 West Madison Street, Chicago,
Illinois 60661.  Such reports, proxy statements and other information may also
be inspected at the offices of the following stock exchanges on which certain of
the Company's securities are listed:  the New York Stock Exchange, 20 Broad
Street, New York, New York 10005; the Pacific Stock Exchange, 301 Pine Street,
San Francisco, California 94104; and The Toronto Stock Exchange, The Exchange
Tower, 2 First Canadian Place, Toronto, Ontario, Canada M5X 1J2.

     No separate financial statements of any of the Phillips Capital Trusts have
been included herein.  Phillips does not consider that such financial statements
would be material to holders of the Preferred Securities because (i) all of the
voting securities of each of the Phillips Capital Trusts will be owned, directly
or indirectly, by Phillips, a reporting company under the Exchange Act, (ii)
each of the Phillips Capital Trusts has no independent operations but exists for
the sole purpose of issuing securities representing undivided beneficial
interests in the assets of such Phillips Capital Trust and investing the
proceeds thereof in Subordinated Debt Securities issued by Phillips, and (iii)
Phillips' obligations described herein and in any accompanying Prospectus
Supplement under the Declarations of each Trust, the guarantee issued with
respect to Preferred Securities issued by that Trust, the Subordinated Debt
Securities purchased by that Trust and the related Indenture, taken together,
constitute a full and unconditional guarantee of payments due on the Preferred
Securities.  See "Description of the Subordinated Debt Securities" and
"Description of the Preferred Securities Guarantees."

     The Phillips Capital Trusts are not currently subject to the information
reporting requirements of the Exchange Act.  The Phillips Capital Trusts will
become subject to such requirements upon the effectiveness of the Registration
Statement, although they intend to seek and expect to receive exemptions
therefrom.

                           PHILLIPS PETROLEUM COMPANY

     Phillips Petroleum Company, incorporated in Delaware in 1917, is a fully
integrated oil company engaged in petroleum exploration and production on a
worldwide basis, petroleum refining and marketing, and natural gas gathering and
processing, principally in the United States.  Phillips also produces and
distributes chemicals worldwide.  Its principal executive offices are located in
the Phillips Building, Bartlesville, Oklahoma 74004 (telephone (918) 661-6600).

                                   THE TRUSTS

     Each of Phillips 66 Capital I, Phillips 66 Capital II, Phillips 66 Capital
III and Phillips 66 Capital IV is a statutory business trust formed under
Delaware law pursuant to (i) a separate declaration of trust (each a
"Declaration") executed by the Company, as sponsor for such trust (the
"Sponsor") and the Phillips Capital Trustees (as defined herein) for such trust
and (ii) the filing of a certificate of trust with the Delaware Secretary of
State on February 23, 1996.  Each Phillips Capital Trust exists for the
exclusive purposes of (i) issuing the Preferred Securities and common securities
representing undivided beneficial interests in the assets of such Trust (the
"Common Securities" and, together with the Preferred Securities, the "Trust
Securities"), (ii) investing the gross proceeds of the Trust Securities in the
Subordinated Debt Securities and (iii) engaging in only those other activities
necessary or incidental thereto.  All of the Common Securities will be directly
or indirectly owned by the Company.  The Common Securities will rank pari passu,
and payments will be made thereon pro rata, with the Preferred Securities except
that upon an event of default under the Declaration, the rights of the holders
of the Common Securities to payment in respect of distributions and payments
upon liquidation, redemption and otherwise will be subordinated to the rights of
the holders of the Preferred Securities.  The Company will, directly or
indirectly, acquire Common Securities in an aggregate liquidation amount equal
to 3 percent of the total capital of each Phillips Capital Trust.  Each Phillips
Capital Trust has a term of approximately 55 years, but may earlier terminate as
provided in the Declaration.  Each Phillips Capital Trust's business and affairs
will be conducted by the trustees (the "Phillips Capital Trustees") appointed by
the Company, as the direct or indirect holder of all the Common Securities.  The
holder of the Common Securities will be entitled to appoint,


                                      -4-
<PAGE>   41
remove or replace any of, or increase or reduce the number of, the Phillips
Capital Trustees of a Phillips Capital Trust.  The duties and obligations of the
Phillips Capital Trustees shall be governed by the Declaration of such Phillips
Capital Trust.  A majority of the Phillips Capital Trustees (the "Regular
Trustees") of each Phillips Capital Trust will be persons who are employees or
officers of or affiliated with the Company.  One Phillips Capital Trustee of
each Phillips Capital Trust will be a financial institution which will be
unaffiliated with the Company and which shall act as property trustee and as
indenture trustee for purposes of the Trust Indenture Act of 1939, as amended
(the "Trust Indenture Act"), pursuant to the terms set forth in a Prospectus
Supplement (the "Property Trustee").  In addition, unless the Property Trustee
maintains a principal place of business in the State of Delaware, and otherwise
meets the requirements of applicable law, one Phillips Capital Trustee of each
Phillips Capital Trust will have its principal place of business or reside in
the State of Delaware (the "Delaware Trustee").  The Company will pay all fees
and expenses related to the Phillips Capital Trusts and the offering of Trust
Securities, the payment of which will be guaranteed by the Company.  The office
of the Delaware Trustee for each Phillips Capital Trust in the State of
Delaware is The Bank of New York (Delaware), White Clay Center, Route 273,
Newark, Delaware 19711.  The principal place of business of each Phillips
Capital Trust shall be c/o Phillips Petroleum Company, 3 Phillips Building,
Bartlesville, Oklahoma 74004.  


                       RATIO OF EARNINGS TO FIXED CHARGES

     The following table sets forth the ratio of earnings to fixed charges for
the periods indicated:

Ratio of earnings to fixed charges.   3.4    3.2    2.3    2.1    2.0
</TABLE>

     For the purpose of computing the ratio of earnings to fixed charges,
earnings consist of income before income taxes, extraordinary items and
cumulative effect of changes in accounting principle, plus fixed charges
(excluding capitalized interest and the portion of the preferred dividend
requirements of a subsidiary not previously deducted from pretax income, but
including amortization of amounts previously capitalized), less equity in
undistributed earnings of companies owned less than 50 percent.  Fixed charges
consist of interest (including capitalized interest) on all indebtedness,
amortization of debt discount and expense, that portion of rental expense which
the Company believes to be representative of interest and the amounts accrued to
cover the preferred stock dividend requirements of a subsidiary.  A statement
setting forth the computation of the unaudited ratios of earnings to fixed
charges is filed as an exhibit to the Registration Statement of which this
Prospectus is a part.


                                USE OF PROCEEDS

     The Trust will use all proceeds received from the sale of the Preferred
Securities to purchase Subordinated Debt Securities from Phillips.  Phillips
intends to add the net proceeds from the sale of the Subordinated Debt
Securities to its general funds, to be used for general corporate purposes,
including capital expenditures, repayment or repurchases of outstanding
long-term debt securities, investments in subsidiaries, working capital,

                DESCRIPTION OF THE SUBORDINATED DEBT SECURITIES

   
     Subordinated Debt Securities may be issued from time to time in one or more
series under an Indenture (the "Indenture"), between the Company and The Bank of
New York, as Trustee (the "Debt Trustee").  The terms of the Subordinated Debt
Securities will include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act. The following summary of the
material terms does not purport to be complete and is subject in all respects
to the provisions of, and is qualified in its entirety by reference to, the
Indenture, which is filed as an exhibit to the Registration Statement of which
this Prospectus forms a part, and the Trust Indenture Act.  Whenever particular
provisions or defined terms in the Indenture are referred to herein, such
provisions or defined terms are incorporated by reference herein.  Section and
Article references used herein are references to provisions of the Indenture
unless otherwise noted.
    

GENERAL

     The Subordinated Debt Securities will be unsecured, subordinated
obligations of the Company.  The Indenture does not limit the aggregate
principal amount of Subordinated Debt Securities which may be issued thereunder
and provides that the Subordinated Debt Securities may be issued from time to
time in one or more series.  The Subordinated Debt Securities are issuable in
one or more series pursuant to an indenture supplemental to the Indenture or a
resolution of the Company's Board of Directors or a special committee appointed
thereby (each, a "Supplemental Indenture"). (Section 2.03)

     In the event Subordinated Debt Securities are issued to a Phillips Capital
Trust or a trustee of such trust in connection with the issuance of Trust
Securities by such Phillips Capital Trust, such Subordinated Debt Securities
subsequently may be distributed pro rata to the holders of such Trust Securities
in connection with the dissolution of such Phillips Capital Trust upon the
occurrence of certain events described in the Prospectus Supplement relating to
such Trust Securities.  Only one series of Subordinated Debt Securities will be
issued to a Phillips Capital Trust or a trustee of such trust in connection with
the issuance of Trust Securities by such Phillips Capital Trust.

     Reference is made to the Prospectus Supplement relating to the particular
Subordinated Debt Securities being offered thereby for the following terms: (1)
the designation of such Subordinated Debt Securities; (2) the aggregate
principal amount of such Subordinated Debt Securities; (3) the percentage of
their principal amount at which such Subordinated Debt Securities will be
issued, (4) the date or dates on which such Subordinated Debt Securities will
mature and the right, if any, to extend such date or dates; (5) the rate or
rates, if any, per annum, at which such Subordinated Debt Securities will bear
interest, or the method of determination of such rate or rates; (6) the date or
dates from which such interest shall accrue, the interest payment dates on which
such interest will be payable or the manner of determination of such interest
payment dates and the record dates for the determination of holders to whom
interest is payable on any such interest payment dates; (7) the right, if any,
to extend the interest payment periods and the duration of such extension; (8)
provisions for a sinking purchase or other analogous fund, if any; (9) the
period or periods, if any, within which, the price or prices of which, and the
terms and conditions upon which  such Subordinated Debt Securities may be
redeemed, in whole or in part, at the option of the Company or the holder; (10)
the form of such Subordinated Debt Securities; and (11) any other specific terms
of the Subordinated Debt Securities.  Principal, premium, if any, and interest,
if any, will be payable, and the Subordinated Debt Securities offered hereby
will be transferable, at the corporate trust office of the Debt Trustee in New
York, New York, provided that payment of interest, if any, may be made at the
option of the Company by check mailed to the address of the person entitled
thereto as it appears in the Security Register.  (Sections 3.01 and 3.02)

     If a Prospectus Supplement specifies that a series of Subordinated Debt
Securities is denominated in a currency or currency unit other than United
States dollars, such Prospectus Supplement shall also specify the denomination
in which such Subordinated Debt Securities will be issued and the coin or
currency in which the principal, premium, if any, and interest, if any, on such
Subordinated Debt Securities will be payable, which

                                      -6-
<PAGE>   43
may be United States dollars based upon the exchange rate for such other
currency or currency unit existing on or about the time a payment is due.


     The Indenture contains no covenants or other provisions to afford
protection to holders of the Subordinated Debt Securities in the event of a
highly leveraged transaction or a change in control of the Company, except to
the limited extent described under "Limitation on Mergers and Sales of Assets"
below.

FORM, EXCHANGE, REGISTRATION, TRANSFER AND PAYMENT

     Unless otherwise specified in the applicable Prospectus Supplement, the
Subordinated Debt Securities will be issued in fully registered form without
coupons and in denominations of $1,000 and multiples of $1,000.  No service
charge will be made for any transfer or exchange of the Subordinated Debt
Securities, but the Company or the Debt Trustee may require payment of a sum
sufficient to cover any tax or other government charge payable in connection
therewith.  Where Subordinated Debt Securities of any series are issued in
bearer form, the special restrictions and considerations, including special
offering restrictions and special United States federal income tax
considerations, applicable to any such Subordinated Debt Securities and to
payment on and transfer and exchange of such Subordinated Debt Securities will
be described in the applicable Prospectus Supplement.  Bearer Subordinated Debt
Securities will be transferrable by delivery.

     Unless otherwise provided in the applicable Prospectus Supplement,
principal and premium, if any, or interest, if any, will be payable and the
Subordinated Debt Securities may be surrendered for payment or transferred at
the offices of the Debt Trustee as paying and authenticating agent, provided
that payment of interest on registered securities may be made at the option of
the Company by check mailed to the address of the person entitled thereto as it
appears in the Security Register.  Payment of Subordinated Debt Securities in
bearer form will be made at such paying agencies outside of the United States
as the Company may appoint.

BOOK-ENTRY SUBORDINATED DEBT SECURITIES

     The Subordinated Debt Securities of a series may be issued in whole or in
part in the form of one or more Global Securities that will be deposited with,
or on behalf of, a depositary (the "Global Depositary"), or its nominee,
identified in the Prospectus Supplement relating to such series.  In such a
case, one or more Global Securities will be issued in a denomination or
aggregate denomination equal to the portion of the aggregate principal amount of
Outstanding Subordinated Debt Securities of the series to be represented by such
Global Security or Securities.  Unless and until it is exchanged in whole or in
part for Subordinated Debt Securities in definitive registered form, a Global
Security may not be registered for transfer or exchange except as a whole by the
Global Depositary for such Global Security to a nominee for such Global
Depositary and except in the circumstances described in the applicable
Prospectus Supplement.

     The specific terms of the depositary arrangement with respect to any
portion of a series of Subordinated Debt Securities to be represented by a
Global Security and a description of the Global Depositary will be provided in
the applicable Prospectus Supplement.


SUBORDINATION

     The Subordinated Debt Securities will be subordinated and junior in right
of payment to certain other indebtedness of the Company to the extent set forth
in the applicable Prospectus Supplement.

Default (as defined herein) or (ii) the Company shall be in default with respect
to its payment of any obligations under the related Preferred Securities
Guarantee or Common Securities Guarantee, then (a) the Company shall not declare
or pay any dividend on, make any distributions with respect to, or redeem,

interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities (including guarantees) issued by the Company which rank pari

     If Subordinated Debt Securities are issued to a Phillips Capital Trust or a
trustee of such trust in connection with the issuance of Trust Securities by
such Phillips Capital Trust and the Company shall have given notice of its
election to defer payments of interest on such Subordinated Debt Securities by
extending the interest payment period as provided in the Indenture and such
period, or any extension thereof, shall be continuing, then (a) the Company
shall not declare or pay any dividend on, make any distributions with respect
to, or redeem, purchase or make a liquidation payment with respect to, any of
its capital stock, and (b) the Company shall not make any payment of interest,
principal or premium, if any, on or repay, repurchase or redeem any debt

Trust or a trustee of such trust in connection with the issuance of Trust
Securities of such Phillips Capital Trust, for so long as such Trust Securities
remain outstanding, the Company will covenant (i) to directly or indirectly
maintain 100%  ownership of the Common Securities of such Phillips Capital
Trust; provided, however, that any permitted successor of the Company under the
Indenture may succeed to the Company's ownership of such Common Securities, (ii)
to use its reasonable efforts to cause such Phillips Capital Trust (a) to remain
a statutory business trust, except in connection with the distribution of
Subordinated Debt Securities to the holders of Trust Securities in liquidation
of such Phillips Capital Trust, the redemption of all of the Trust Securities of
such Phillips Capital Trust, or certain mergers, consolidations or
amalgamations, each as permitted by the Declaration of such Phillips Capital
Trust, and (b) to otherwise continue not to be classified as an association
taxable as a corporation or partnership for United States federal income tax

Securities to be treated as owning an undivided beneficial interest in the
Subordinated Debt Securities.  (Section 3.09)

LIMITATION ON MERGERS AND SALES OF ASSETS

     The Company shall not consolidate with, or merge into, any corporation or
convey or transfer its properties and assets substantially as an entirety to any
Person unless the successor entity shall be a corporation organized under the

expressly assume the obligations of the Company under the Indenture. (Section
10.01)

<PAGE>   45
EVENTS OF DEFAULT, WAIVER AND NOTICE

     The Indenture provides than any one or more of the following described
events which has occurred and is continuing constitutes an "Event of Default"
with respect to each series of Subordinated Debt Securities:

      (a)     default for 30 days in payment of any interest on the Subordinated
      Debt Securities of that series, including any Additional Interest in
      respect thereof, when due; provided, however, that a valid extension of
      the interest payment period by the Company shall not constitute a default
      in the payment of interest for this purpose; or

      (b)     default in payment of principal and premium, if any, on the
      Subordinated Debt Securities of that series when due either at maturity,
      upon redemption, by declaration or otherwise; provided, however, that a
      valid extension of the maturity of such Subordinated Debt Securities shall
      not constitute a default for this purpose; or

      (c)     default by the Company in the performance of any other of the
      covenants or agreements in the Indenture which shall not have been
      remedied for a period of 90 days after notice; or

      (d)     certain events of bankruptcy, insolvency or reorganization of the
      Company; or

      (e)     in the event Subordinated Debt Securities are issued to a Phillips
      Capital Trust or a trustee of such trust in connection with the issuance
      of Trust Securities by such Phillips Capital Trust, the voluntary or
      involuntary dissolution, winding-up or termination of such Phillips
      Capital Trust, except in connection with the distribution of Subordinated
      Debt Securities to the holders of Trust Securities in liquidation of such
      Phillips Capital Trust, the redemption of all of the Trust Securities of
      such Phillips Capital Trust, or certain mergers, consolidations or
      amalgamations, each as permitted by the Declaration of such Phillips
      Capital Trust.

(Section 5.01)  The Indenture provides that the Debt Trustee may withhold notice
to the holders of a series of Subordinated Debt Securities (except in payment of
principal or of interest or premium on the Subordinated Debt Securities) if the
Trustee considers it in the interest of such holders to do so.  (Section 5.08).

     The Indenture provides that, (a) if an Event of Default due to the default
in the payment of principal, interest or premium, if any, on any series of
Subordinated Debt Securities shall have occurred and be continuing, either the
Debt Trustee or the holders of 25 percent in principal amount of the
Subordinated Debt Securities of all series affected thereby then outstanding may
declare the principal of all such Subordinated Debt Securities to be due and
payable immediately, and (b) if an Event of Default resulting from default in
the performance of any other of the covenants or agreements in the Indenture or
certain events of bankruptcy, insolvency and reorganization of the Company shall
have occurred and be continuing, either the Debt Trustee or the holders of 25
percent in principal amount of all Subordinated Debt Securities then outstanding
(treated as one class) may declare the principal of all Subordinated Debt
Securities to be due and payable immediately, but upon certain conditions such
declarations may be annulled and past defaults may be waived (except defaults in
payment of principal of or interest or premium on the Subordinated Debt
Securities) by the holders of a majority in principal amount of the Subordinated
Debt Securities of such series (or of all series, as the case may be) then
outstanding.  (Section 5.01)

     The holders of a majority in principal amount of the Subordinated Debt
Securities of any and all series affected and then outstanding shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Debt Trustee under the Indenture, provided that the
holders of the Subordinated Debt Securities shall have offered to the Debt
Trustee reasonable indemnity against expenses and liabilities.  (Sections 5.07
and 5.04)  The Indenture requires the annual filing by the Company with the Debt
Trustee of a certificate as to the absence of certain defaults under the
Indenture.  (Section 3.07)

<PAGE>   46
MODIFICATION OF THE INDENTURE

     The Indenture contains provisions permitting the Company and the Debt
Trustee, with the consent of the holders of not less than a majority in
principal amount of the Subordinated Debt Securities of all series affected by
such modification at the time outstanding, to modify the Indenture or any
supplemental indenture or the rights of the holders of the Subordinated Debt
Securities; provided that no such modification shall (i) extend the fixed
maturity of any Security, or reduce the principal amount thereof (including in
the case of a discounted Security the amount payable thereon in the event of
acceleration or the amount provable in bankruptcy) or any redemption premium
thereon, or reduce the rate or extend the time of payment of interest thereon,
or make the principal of, or interest or premium on, the Subordinated Debt
Securities payable in any coin or currency other than that provided in the
Subordinated Debt Securities, or impair or affect the right of any holder of
Subordinated Debt Securities to institute suit for the payment thereof or the
right of prepayment, if any, at the option of the holder, without the consent of
the holder of each Security so affected, or (ii) reduce the aforesaid percentage
of Subordinated Debt Securities the consent of the holders of which is required
for any such modification without the consent of the holders of each Security
affected.  (Section 9.02)

DEFEASANCE AND DISCHARGE

     The Indenture provides that the Company, at the Company's option:  (a) will
be Discharged from any and all obligations in respect of the Subordinated Debt
Securities of a series (except for certain obligations to register the transfer
or exchange of Subordinated Debt Securities, replace stolen, lost or mutilated
Subordinated Debt Securities, maintain paying agencies and hold moneys for
payment in trust) or (b) need not comply with certain restrictive covenants of
the Indenture (including those described under "Certain Covenants of the
Company"), in each case if the Company deposits, in trust with the Debt Trustee
or the Defeasance Agent, money or U.S. Government Obligations which through the
payment of interest thereon and principal thereof in accordance with their terms
will provide money, in an amount sufficient to pay all the principal (including
any mandatory sinking fund payments) of, and interest and premium, if any, on,
the Subordinated Debt Securities of such series on the dates such payments are
due in accordance with the terms of such Subordinated Debt Securities.  To
exercise any such option, the Company is required to deliver to the Debt Trustee
and the Defeasance Agent, if any, an opinion of counsel to the effect that (i)
the deposit and related defeasance would not cause the holders of the
Subordinated Debt Securities of such series to recognize income, gain or loss
for federal income tax purposes and, in the case of a Discharge pursuant to
clause (a), such opinion shall be accompanied by a private letter ruling to the
effect received from the United States Internal Revenue Service or a revenue
ruling pertaining to a comparable form of transaction to the effect published by
the United States Internal Revenue Service, and (ii) if listed on any national
securities exchange, such Subordinated Debt Securities would not be delisted
from such exchange as a result of the exercise of such option.  (Section 11.05)

GOVERNING LAW

     The Indenture and the Subordinated Debt Securities will be governed by, and
construed in accordance with, the internal laws of the State of New York.
(Section 13.04).

THE DEBT TRUSTEE

     The Company may have normal banking relationships with the Debt Trustee in
the ordinary course of business.

                    DESCRIPTION OF THE PREFERRED SECURITIES

   
     Each Phillips Capital Trust may issue, from time to time, only one series
of Preferred Securities having terms described in the Prospectus Supplement
relating thereto.  The Declaration of each Phillips Capital Trust authorizes the
Regular Trustees of such Phillips Capital Trust to issue on behalf of such
Phillips Capital Trust one series of Preferred Securities.  The Declaration will
be qualified as an indenture under the Trust Indenture Act.  The Preferred
Securities will have such terms, including distributions, redemption, voting,
liquidation rights and such other preferred, deferred or other special rights or
such restrictions as shall be set forth in the Declaration or made part of the
Declaration by the Trust Indenture Act and which will mirror the terms of the
Subordinated Debt Securities held by the Phillips Capital Trust and described
in the Prospectus Supplement relating thereto.  Reference is made to the
Prospectus Supplement relating to the Preferred Securities of the Phillips
Capital Trust for specific terms, including (i) the distinctive designation of
such Preferred Securities; (ii) the number of Preferred Securities issued by
such Phillips Capital Trust; (iii) the annual distribution rate (or method of
determining such rate) for Preferred Securities issued by such Phillips Capital
Trust and the date or dates upon which such distributions shall be payable;
provided, however, that distributions on such Preferred Securities shall be
payable on a quarterly basis to holders of such Preferred Securities as of a
record date in each quarter during which such Preferred Securities are
outstanding; (iv) whether distributions on Preferred Securities issued by such
Phillips Capital Trust shall be cumulative, and, in the case of Preferred
Securities having such cumulative distribution rights, the date or dates or
method of determining the date or dates from which distributions on Preferred
Securities issued by such Phillips Capital Trust shall be cumulative; (v) the
amount or amounts which shall be paid out of the assets of such Phillips
Capital Trust to the holders of Preferred Securities of such Phillips Capital
Trust upon voluntary or involuntary dissolution, winding-up or termination of
such Phillips Capital Trust; (vi) the obligation, if any, of such Phillips
Capital Trust to purchase or redeem Preferred Securities issued by such
Phillips Capital Trust and the price or prices at which, the period or periods
within which, and the terms and conditions upon which, Preferred Securities
issued by such Phillips Capital Trust shall be purchased or redeemed, in whole
or in part, pursuant to such obligation; (vii) the voting rights, if any, of
Preferred Securities issued by such Phillips Capital Trust in addition to those
required by law, including the number of votes per Preferred Security and any
requirement for the approval by the holders of Preferred Securities, or of
Preferred Securities issued by one or more Phillips Capital Trusts, or of both,
as a condition to specified action or amendments to the Declaration of such
Phillips Capital Trust; (viii) the terms and conditions, if any, upon which the
Subordinated Debt Securities may be distributed to holders of Preferred
Securities; (ix) if applicable, any securities exchange upon which the
Preferred Securities shall be listed; and (x) any other relevant rights,
preferences, privileges, limitations or restrictions of Preferred Securities
issued by such Phillips Capital Trust not inconsistent with the Declaration of
such Phillips Capital Trust or with applicable law.  All Preferred Securities
offered hereby will be guaranteed by the Company to the extent set forth below
under "Description of the Preferred Securities Guarantees."  Certain United
States federal income tax considerations applicable to any offering of
Preferred Securities will be described in the Prospectus Supplement relating
thereto.
    

     In connection with the issuance of Preferred Securities, each Phillips
Capital Trust will issue one series of Common Securities.  The Declaration of
each Phillips Capital Trust authorizes the Regular Trustees of such trust to
issue on behalf of such Phillips Capital Trust one series of Common Securities
having such terms including distributions, redemption, voting, liquidation
rights or such restrictions as shall be set forth therein.  The terms of the
Common Securities issued by a Phillips Capital Trust will be substantially
identical to the terms of the Preferred Securities issued by such trust and the
Common Securities will rank pari passu, and payments will be made thereon pro
rata, with the Preferred Securities except that, upon an event of default under
the Declaration, the rights of the holders of the Common Securities to payment
in respect of distributions and payments upon liquidation, redemption and
otherwise will be subordinated to the rights of the holders of the Preferred
Securities.  Except in certain limited circumstances, the Common Securities will
also carry the right to vote to appoint, remove or replace any of the Phillips
Capital Trustees of a Phillips Capital Trust.  All of the Common Securities of
each Phillips Capital Trust will be directly or indirectly owned by the Company.

   
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF TRUST PREFERRED SECURITIES
    

   
     If an Event of Default under the Declaration of a Phillips Capital Trust
occurs and is continuing, then the holders of Preferred Securities of such
Phillips Capital Trust would rely on the enforcement by the Institutional
Trustee of its rights as a holder of the applicable series of Subordinated Debt
Securities against the Company. In addition, the holders of a majority in
liquidation amount of the Preferred Securities of such Phillips Capital Trust
will have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Institutional Trustee or to direct
the exercise of any trust or power conferred upon the Institutional Trustee
under the applicable Declaration, including the right to direct the
Institutional Trustee to exercise the remedies available to it as a holder of
the Subordinated Debt Securities. If the Institutional Trustee fails to enforce
its rights under the applicable series of Subordinated Debt Securities, a
holder of Preferred Securities of such Phillips Capital Trust may institute a
legal proceeding directly against the Company to enforce the Institutional
Trustee's rights under the applicable series of Subordinated Debt Securities
without first instituting any legal proceeding against the Institutional
Trustee or any other person or entity. Notwithstanding the foregoing, if an
Event of Default under the applicable Declaration has occurred and is continuing
and such event is attributable to the failure of the Company to pay interest or
principal on the applicable series of Subordinated Debt Securities on the date
such interest or principal is otherwise payable (or in the case of redemption,
on the redemption date), then a holder of Preferred Securities of such Phillips
Capital Trust may directly institute a proceeding for enforcement of payment to
such holder of the principal of or interest on the applicable series of
Subordinated Debt Securities having a principal amount equal to the aggregate
liquidation amount of the Preferred Securities of such holder (a "Direct
Action") on or after the respective due date specified in the applicable series
of Subordinated Debt Securities. In connection with such Direct Action, the
Company will be subrogated to the rights of such holder of Preferred Securities
under the applicable Declaration to the extent of any payment made by the
Company to such holder of Preferred Securities in such Direct Action.
    

   
PROPOSED TAX LEGISLATION
    

   
     On March 19, 1996, President Clinton proposed certain tax law changes as
part of his fiscal 1997 budget that would, among other things, generally deny
corporate issuers a deduction for interest in respect of certain debt
obligations issued on or after December 7, 1995 (the "Proposed Legislation") if
such debt obligations have a maximum term in excess of twenty years and are not
shown as indebtedness on the issuer's applicable consolidated balance sheet. In
addition, the Proposed Legislation would deny issuers an interest deduction on
any debt instruments with a weighted average maturity of greater than 40 years.
On March 29, 1996, Senate Finance Committee Chairman William V. Roth, Jr. and
House Ways and Means Committee Chairman Bill Archer issued a joint statement
(the "Joint Statement") indicating their intent that certain legislative
proposals initiated by the Clinton administration, including the Proposed
Legislation, that may be adopted by either of the tax-writing committees of
Congress would have an effective date that is no earlier than the date of
"appropriate Congressional action." Based upon the Joint Statement, it is
expected that if the Proposed Legislation were to be enacted, such Legislation
would not apply to a series of Subordinated Debt Securities if the series (i)
was issued prior to the date of "appropriate Congressional action" or (ii) had
a maximum term that did not exceed 20 years. The Company intends that any
series of Subordinated Debt Securities will either be issued prior to the date
of "appropriate Congressional action" or will have a maximum term that does not
exceed 20 years. Accordingly, the Company does not expect the Proposed
Legislation to apply to any series of Subordinated Debt Securities. There can
be no assurances, however, that the effective date guidance contained in the
Joint Statement will be incorporated into the Proposed Legislation, if enacted,
or that other legislation enacted after the date hereof will not otherwise
adversely affect the ability of the Company to deduct the interest payable on
any series of Subordinated Debt Securities. Accordingly, there can be no
assurance that a Tax Event will not occur.

               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 Phillips for the
benefit of the holders from time to time of Preferred Securities.  Each
Preferred Securities Guarantee will be qualified as an indenture under the Trust
Indenture Act.  The Bank of New York will act as indenture trustee under each
Preferred Securities Guarantee for purposes of the Trust Indenture Act (the
"Preferred Guarantee Trustee").  The terms of each Preferred Securities
Guarantee will be those set forth in such Preferred Securities Guarantee and
those made part of such Preferred Securities Guarantee by the Trust Indenture
Act.  The summary of the material terms of the Preferred Securities Guarantees
does not purport to be complete and is subject in all respects to the
provisions of, and is qualified in its entirety by reference to, the form of
Preferred Securities Guarantee, which is filed as an exhibit to the
Registration Statement of which this Prospectus forms a part, and the Trust
Indenture Act.  Each Preferred Securities Guarantee will be held by the
Preferred Guarantee Trustee for the benefit of the holders of the Preferred
Securities of the applicable Phillips Capital Trust.
    

GENERAL

   
     Pursuant to each Preferred Securities Guarantee, the Company will
irrevocably and unconditionally agree, to the extent set forth therein, to pay
in full, to the holders of the Preferred Securities issued by a Phillips Capital
Trust, the Guarantee Payments (as defined herein) (except to the extent paid by
such Phillips Capital Trust), as and when due, regardless of any defense, right
of set-off or counterclaim which such Phillips Capital Trust may have or assert.
The following payments with respect to Preferred Securities issued by a Phillips
Capital Trust to the extent not paid by such Phillips Capital Trust (the
"Guarantee Payments"), will be subject to the Preferred Securities Guarantee
thereon (without duplication):  (i) any accrued and unpaid distributions which
are required to be paid on such Preferred Securities, to the extent such
Phillips Capital Trust shall have funds available therefor; (ii) the redemption
price, including all accrued and unpaid distributions (the "Redemption Price"),
to the extent such Phillips Capital Trust has funds available therefor with
respect to any Preferred Securities called for redemption by such Phillips
Capital Trust and (iii) upon a voluntary or involuntary dissolution, winding-up
or termination of such Phillips Capital Trust (other than in connection with the
distribution of Subordinated Debt Securities to the holders of Preferred
Securities or the redemption of all of the Preferred Securities), the lesser of
(a) the aggregate of the liquidation amount and all accrued and unpaid
distributions on such Preferred Securities to the date of payment, to the extent
such Phillips Capital Trust has funds available therefor and (b) the amount of
assets of such Phillips Capital Trust remaining available for distribution to
holders of such Preferred Securities in liquidation of such Phillips Capital
Trust. The redemption price and liquidation amount will be fixed at the time
the Preferred Securities are issued. The Company's obligation to make a 
Guarantee Payment may be satisfied by direct payment of the required amounts 
by the Company to the holders of Preferred Securities or by causing the 
applicable Phillips Capital Trust to pay such amounts to such holders.
    

   
     Each Preferred Securities Guarantee will not apply to any payment of
distributions except to the extent such Phillips Capital Trust shall have funds
available therefor.  If the Company does not make interest payments on the
Subordinated Debt Securities purchased by a Phillips Capital Trust, such
Phillips Capital Trust will not pay distributions on the Preferred Securities
issued by such Phillips Capital Trust and will not have funds available
therefor.  See "Description of the Subordinated Debt Securities -- Certain
Covenants." The Preferred Securities Guarantee, when taken together with the
Company's obligations under the Subordinated Debt Securities, the Indenture and
the Declaration, including its obligations to pay costs, expenses, debts and
liabilities of such Phillips Capital Trust (other than with respect to the
Trust Securities), will provide a full and unconditional guarantee on a
subordinated basis by the Company of payments due on the Preferred Securities.
    

     The Company has also agreed separately to irrevocably and unconditionally
guarantee the obligations of the Phillips Capital Trusts with respect to the
Common Securities (the "Common Securities Guarantees") to the same extent as the
Preferred Securities Guarantees, except that upon an event of default under the
Indenture, holders of Preferred Securities shall have priority over holders of
Common Securities with respect to distributions and payments on liquidation,
redemption or otherwise.

CERTAIN COVENANTS OF THE COMPANY

     In each Preferred Securities Guarantee, the Company will covenant that, so
long as any Preferred Securities issued by the applicable Phillips Capital Trust
remain outstanding, if there shall have occurred any event that would constitute
an event of default under such Preferred Securities Guarantee or the Declaration
of such Phillips Capital Trust, then (a) the Company shall not declare or pay
any dividend on, make any distributions with respect to, or redeem, purchase or
make liquidation payment with respect to, any of its capital stock (other than
(i) purchases or acquisitions of shares of Phillips Common Stock in connection
with the satisfaction by Phillips of its obligations under any employee benefit
plans or the satisfaction by Phillips of its obligations pursuant to any
contract or security requiring Phillips to purchase shares of Phillips Common
Stock, (ii) as a result of a reclassification of Phillips capital stock or the
exchange or conversion of one class or series of Phillips capital stock for
another class or series of Phillips capital stock or, (iii) the purchase of
fractional interests in shares of Phillips capital stock pursuant to the
conversion or exchange provisions of such Phillips capital stock or the security
being converted or exchanged) or make any guarantee payments with respect to the
foregoing and (b) the Company shall not make any payment of interest, principal
or premium, if any, on or repay, repurchase or redeem any debt securities
(including guarantees) issued by the Company which rank pari passu with or
junior to such Subordinated Debt Securities.

MODIFICATION OF THE PREFERRED SECURITIES GUARANTEES; ASSIGNMENT

     Except with respect to any changes which do not adversely affect the rights
of holders of Preferred Securities (in which case no vote will be required),
each Preferred Securities Guarantee may be amended only with the prior approval
of the holders of not less than a majority in liquidation amount of the
outstanding Preferred Securities issued by the applicable Phillips Capital
Trust.  The manner of obtaining any such approval of holders of such Preferred
Securities will be as set forth in an accompanying Prospectus Supplement.  All
guarantees and agreements contained in a Preferred Securities Guarantee shall
bind the successors, assigns, receivers, trustees and representatives of the
Company and shall inure to the benefit of the holders of the Preferred
Securities of the applicable Phillips Capital Trust then outstanding.

TERMINATION

     Each Preferred Securities Guarantee will terminate as to the Preferred
Securities issued by the applicable Phillips Capital Trust (a) upon full payment
of the Redemption Price of all Preferred Securities of such Phillips Capital
Trust, (b) upon distribution of the Subordinated Debt Securities held by such
Phillips Capital Trust to the holders of the Preferred Securities of such
Phillips Capital Trust or (c) upon full payment of the amounts payable in
accordance with the Declaration of such Phillips Capital Trust upon liquidation
of such Phillips Capital Trust.  Each Preferred Securities Guarantee will
continue to be effective or will be reinstated, as the case may be, if at any
time any holder of Preferred Securities issued by the applicable Phillips
Capital Trust must restore payment of any sums paid under such Preferred
Securities or such Preferred Securities Guarantee.

EVENTS OF DEFAULT

     An event of default under a Preferred Securities Guarantee will occur upon
the failure of the Company to perform any of its payment or other obligations
thereunder.

     The holders of a majority in liquidation amount of the Preferred Securities
relating to such Preferred Securities Guarantee have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Preferred Guarantee Trustee in respect of the Preferred Securities Guarantee
or to direct the exercise of any trust or power conferred upon the Preferred
Guarantee Trustee under such Preferred Securities.  If the Preferred Guarantee
Trustee fails to enforce such Preferred Securities Guarantee, any holder of
Preferred Securities relating to such Preferred Securities Guarantee may
institute a legal proceeding directly against the Company to enforce the
Preferred Guarantee Trustee's rights under such Preferred Securities Guarantee,
without first instituting a legal proceeding against the relevant Phillips
Capital


                                      -13-
<PAGE>   50
Trust, the Preferred Guarantee Trustee or any other person or entity.
Notwithstanding the foregoing, if the Company has failed to make a guarantee
payment, a holder of Preferred Securities may directly institute a proceeding
against the Company for enforcement of the Preferred Securities Guarantee for
such payment.  The Company waives any right or remedy to require that any action
be brought first against such Phillips Capital Trust or any other person or
entity before proceeding directly against the Company.

STATUS OF THE PREFERRED SECURITIES GUARANTEES

     The Preferred Securities Guarantees will constitute unsecured obligations
of the Company and will rank (i) subordinate and junior in right of payment to
all other liabilities of the Company, (ii) pari passu with the most senior
preferred or preference stock now or hereafter issued by the Company and with
any guarantee now or hereafter entered into by Phillips in respect of any
preferred or preference stock of any affiliate of the Company; and (iii) senior
to the Company's common stock.  The terms of the Preferred Securities provide
that each holder of Preferred Securities issued by the applicable Phillips
Capital Trust by acceptance thereof agrees to the subordination provisions and
other terms of the Preferred Securities Guarantee relating thereto.

     The Preferred Securities Guarantees will constitute a guarantee of payment
and not of collection (that is, the guaranteed party may institute a legal
proceeding directly against the guarantor to enforce its rights under the
Preferred Securities Guarantee without instituting a legal proceeding against
any other person or entity).

INFORMATION CONCERNING THE PREFERRED GUARANTEE TRUSTEE

     The Preferred Guarantee Trustee, prior to the occurrence of a default with
respect to a Preferred Securities Guarantee, undertakes to perform only such
duties as are specifically set forth in such Preferred Securities Guarantee 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. Subject to such
provisions, the Preferred 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 offered reasonable
indemnity against the costs, expenses and liabilities which might be incurred
thereby.

     The Company and certain of its affiliates maintain a banking relationship
with the Preferred Guarantee Trustee.

GOVERNING LAW

     The Preferred Securities Guarantees will be governed by and construed in
accordance with the internal laws of the State of New York.

Prospectus Supplement.

     Agents, underwriters, and dealers may be entitled under the relevant
agreements to indemnification by Phillips and/or any Phillips Capital Trust, as

            ------------------------
            *    To be completed by amendment

ITEM 15.   INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article III, section 14 of the Bylaws of the Company, as amended, provides
for indemnification of officers, directors and employees of the Company to the
extent authorized by the General Corporation Law of the State of Delaware.
Pursuant to Section 145 of the Delaware General Corporation Law, the Company
generally has the power to indemnify its present and former directors, officers,
employees and agents against expenses incurred by them in connection with any
suit to which they are, or are threatened to be made, a party by reason of their
serving in such positions so long as they acted in good faith and in a manner
they reasonably believed to be in, or not opposed to, the best interests of the
corporation, and with respect to any criminal action, they had no reasonable
cause to believe their conduct was unlawful.  With respect to suits by or in the
right of a corporation, however, indemnification is not available if such person
is adjudged to be liable for negligence or misconduct in the performance of his
duty to the corporation unless the court determines that indemnification is
appropriate.  In addition, the Company has the power to purchase and maintain
insurance for such persons.  The statute also expressly provides that the power
to indemnify authorized thereby is not exclusive of any rights granted under any
bylaw, agreement, vote of stockholders or disinterested directors, or otherwise.

     Pursuant to authority conferred by stockholders at the annual meeting of
the Company on April 30, 1987, the Company has entered into Indemnity Agreements
with each of its directors.  The Indemnity Agreements establish contract rights
in favor of the Company's directors and thus give them assurances that the
indemnity provided would continue despite possible future changes or amendments
to the Company's Bylaws or the Restated Certificate of Incorporation.  The
Indemnity Agreements generally provide that the directors are entitled to
indemnification to the fullest extent permitted by law against liabilities
arising from any claims made against them arising from acts or omissions alleged
to have been committed while acting as directors and solely because of their
being directors.

     Also at the annual meeting of the Company on April 30, 1987, stockholders
approved an amendment to the Company's Restated Certificate of Incorporation to
eliminate the personal liability of each director of the Company to the Company
or its shareholders for monetary damages for breach of fiduciary duty


                                      II-1
<PAGE>   54
under certain circumstances.  The amendment is consistent with amendments to the
Delaware General Corporation Law effective July 1, 1986.

     In addition to the indemnification provision of the Company's Bylaws and
the Indemnity Agreements, the Company's directors and officers are covered by
Directors' and Officers' liability insurance with a limit of $100 million, which
insurance is subject to exclusions, deductibles and conditions.

     The above discussion of the Company's Bylaws, Section 145 of the Delaware
General Corporation Law and the Company's Indemnity Agreements with its
directors is not intended to be exhaustive and is respectively qualified in its
entirety by such Bylaws, statute and Agreements.

ITEM 17  UNDERTAKINGS

         (a)  The undersigned Registrants hereby undertake:

               (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, as amended (the "Securities Act"); (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; (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 (a)(1)(i) and (a)(1)(ii) above
      do not apply if the information required to be included in a
      post-effective amendment by those paragraphs is contained in periodic
      reports filed by the Company pursuant to Section 13 or Section 15(d) of
      the Securities Exchange Act of 1934, as amended (the "Exchange Act") that
      are incorporated by reference in the Registration Statement.

               (2)  That, for the purpose of determining any liability under the
      Securities Act, each such 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.

         (b)  The undersigned Registrants hereby undertake that, for purposes of
determining any liability under the Securities Act, each filing of the Company's
annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
(and, where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference
in this 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.

         (c)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrants pursuant to the foregoing provisions, or otherwise, the
Registrants have been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrants of expenses incurred or paid by a director, officer or controlling
person of the Registrants 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 Registrants will, unless in
the opinion of their counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by them is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

         (d)  The undersigned Registrants hereby undertake that:

   
                 (1)  For purposes of determining any liability under the
      Securities act of 1933, the information contained in a form of prospectus
      filed by the Registrants pursuant to Rule 424(b)(1) or (4) or 497(h)
      under the Securities Act shall be deemed to be part of this Registration
      Statement as of the time it was declared effective.
    

                 (2)  For the purpose of determining any liability under the
      Securities Act of 1933, each post-effective amendment that contains a form
      of prospectus 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.

hereinafter be referred to as the "Representative"), with respect to the sale

the Supplemental Indenture (as defined herein) to pay all expenses relating to
administration of the Trust (the "Undertakings").  The Preferred Securities and
the related Preferred Securities Guarantees are referred to herein as the
"Securities."

                 Prior to the purchase and public offering of the Preferred
Securities by the several Underwriters, the Offerors and the Representative,
acting on behalf of the several Underwriters, shall enter into an agreement
substantially in the form of Exhibit A hereto (the "Pricing Agreement").  The
Pricing Agreement may take the form of an exchange of any standard form of
written telecommunication between the Offerors and the Representative and shall
specify such applicable information as is indicated in Exhibit A hereto.  The
offering of the Preferred Securities will be governed by this Agreement, as
supplemented by the Pricing Agreement.  From and after the date of the
execution and delivery of the Pricing Agreement, this Agreement shall be deemed
to incorporate the Pricing Agreement.

                 The Offerors have filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-3 (No.

hereof, and will file such additional amendments thereto and such amended
prospectuses as may hereafter be required.  Such registration statement (as
amended, if applicable) and the prospectus constituting a part thereof
(including, in each case, all documents incorporated or deemed to be
incorporated by reference therein pursuant to Item 12 of Form S-3 under the
1933 Act and the information, if any, deemed to be part thereof pursuant to
Rule 430A(b) or Rule 434 of the rules and regulations of the Commission under
the 1933 Act (the "1933 Act Regulations")), as from time to time amended or
supplemented pursuant to the 1933 Act, the Securities Exchange Act of 1934, as
amended (the "1934 Act"), or otherwise, are hereinafter referred to as the
"Registration Statement" and the "Prospectus," respectively, except that, if
any revised prospectus shall be provided to the Underwriters by the Offerors
for use in connection with the offering of the Preferred Securities which
differs from the Prospectus on file at the Commission at the time the
Registration Statement becomes effective (whether or not such revised
prospectus is required to be filed by the Offerors pursuant to Rule 424(b) of
the 1933 Act Regulations), the term "Prospectus" shall refer to such revised
prospectus from and after the time it is first provided to the Underwriters for
such use.  All references in this Agreement to financial statements and
schedules and other information that is "contained," "included" or "stated" in
the Registration Statement or the Prospectus (and all other references of like
import) shall be deemed to mean and include all such financial statements and
schedules and other information that are or are deemed to be incorporated by
reference in the Registration Statement or the Prospectus, as the case may be;
and all references in this Agreement to amendments or supplements to the
Registration Statement or the Prospectus shall be deemed to mean and include
the filing of any document under the 1934 Act that is or is deemed to be
incorporated by reference in the Registration Statement or the Prospectus, as
the case may be.

                 The Offerors understand that the Underwriters propose to make
a public offering of the Securities as soon as the Representative deems
advisable after the Pricing Agreement has been executed and delivered, and the
Declaration (as defined herein), the Indenture (as defined herein), and the
Preferred Securities Guarantee Agreement have been qualified under the Trust
Indenture Act of 1939, as amended (the "1939 Act").  The entire proceeds from
the sale of the Securities will be combined with the entire proceeds from the
sale by the Trust to the Company of its common securities (the "Common Securi-

Base Indenture and any other amendments or supplements thereto, the
"Indenture"), between the Company and the Debt Trustee.

         subsidiaries, considered as one enterprise.

         and is validly existing as a corporation in good standing under the

         Agreement, the Declaration, the Indenture and each of the Guarantees

         Trust; and the Company is duly qualified as a foreign corporation to
         transact business and is in good standing in each jurisdiction in
         which such qualification is required, whether by reason of the
         ownership or leasing of property or the conduct of business, except
         where the failure so to qualify would not have a material adverse
         effect on the condition, financial or otherwise, or the earnings,

         foreign corporation and is in good standing in each other jurisdiction
         in which it owns or leases property of a nature, or transacts business
         of a type, that would make such qualification necessary, except to the
         extent that the failure to so qualify or be in good standing would not
         have a material adverse effect on the Company and its subsidiaries,

         capital stock of each Subsidiary have been duly authorized and validly
         issued and are fully paid and non- assessable and are owned by the
         Company free and clear of any pledge, lien, security interest, charge,

         thereof may be limited by bankruptcy, insolvency, reorganization,
         moratorium or other similar laws affecting creditors rights generally

                 Section 2.       Sale and Delivery to Underwriters; Closing.

                          (a)  On the basis of the representations and
warranties herein contained and subject to the terms and conditions herein set
forth, the Trust agrees to sell to each Underwriter, severally and not jointly,
and each Underwriter, severally and not jointly, agrees to purchase from the
Trust, at the price per security set forth in the Pricing Agreement, the number
of Preferred Securities set forth in Schedule A opposite the name of such
Underwriter (except as otherwise provided in the Pricing Agreement), plus any
additional number of Preferred Securities that such Underwriter may become
obligated to purchase pursuant to the provisions of Section 10 hereof.

                 The purchase price per security to be paid by the several
Underwriters for the Preferred Securities shall be an amount equal to the
initial public offering price.  The initial public offering price per Preferred
Security shall be a fixed price to be determined by agreement between the
Representative and the Offerors.  The initial public offering price and the
purchase price, when so determined, shall be set forth in the Pricing
Agreement.  In the event that such prices have not been agreed upon and the
Pricing Agreement has not been executed and delivered by all parties thereto by
the close of business on the fourth business day following the date of this
Agreement, this Agreement shall terminate forthwith, without liability of any
party to any other party,





                                       16

unless otherwise agreed to by the Offerors and the Representative.  As
compensation to the Underwriters for their commitments hereunder and in view of
the fact that the proceeds of the sale of the Preferred Securities will be used
to purchase the Subordinated Debt Securities of the Company, the Company hereby
agrees to pay at Closing Time (as defined below) to the Representative, for the
accounts of the several Underwriters, a commission per Preferred Security
determined by agreement between the Representative and the Company for the
Preferred Securities to be delivered by the Trust hereunder at Closing Time.
The commission, when so determined, shall be set forth in the Pricing
Agreement.

                          (b)  Payment of the purchase price for, and delivery
of certificates for, the Preferred Securities shall be made at the office of
Skadden, Arps, Slate, Meagher & Flom, or at such other place as shall be agreed
upon by the Representative and the Trust, at 10:00 A.M. New York time on the
third or fourth business day (as permitted under Rule 15c6-1 of the 1934 Act)
(unless postponed in accordance with the provisions of Section 10) after
execution of the Pricing Agreement, or such other time not later than ten
business days after such date as shall be agreed upon by the Representative,
the Trust, the Company (such time and date of payment and delivery being herein
called "Closing Time").  Payment shall be made to the Trust by certified or

of the Underwriters of certificates for the Preferred Securities to be
purchased by them.  Certificates for the Preferred Securities shall be in such
denominations and registered in such names as the Representative may request in
writing at least two business days before the Closing Time.  It is understood

accept delivery of, receipt for, and make payment of the purchase price for,
the Preferred Securities which it has agreed to purchase.  Merrill Lynch,
individually and not as Representative of the Underwriters, may (but shall not
be obligated to) make payment of the purchase price for the Preferred
Securities to be purchased by any Underwriter whose check has not been received
by the Closing Time, but such payment shall not relieve such Underwriter from
its obligations hereunder.

                 The certificate(s) for the Preferred Securities will be made
available for examination and packaging by





                                       17

the Closing Time.

                 At the Closing Time, the Company will pay, or cause to be
paid, the commission payable at such time to the Underwriters under Section 2
hereof by certified or official bank check or checks payable to Merrill Lynch,
Pierce, Fenner & Smith Incorporated in New York Clearing House funds or other
similar next day funds.

jointly and severally covenant with each Underwriter as follows:

Offerors propose for use by the Underwriters in connection with the offering of
the Preferred Securities which differs from the prospectus on file at the
Commission at the time the Registration Statement becomes effective, whether or
not such revised prospectus is required to be filed pursuant to Rule 424(b) of
the 1933 Act Regulations), or (iii) any document that would as a result thereof
be incorporated by reference in the Prospectus whether pursuant to the 1933
Act, the 1934 Act or otherwise, will furnish the Representative with copies of
any such amendment, supplement or other document a reasonable amount of time
prior to such proposed filing or use, as the case may be, and will not file any
such amendment, supplement or other document or use any such prospectus to
which the Representative or counsel for the Underwriters shall reasonably
object.  Subject to the foregoing, the Offerors will promptly





                                       18
<PAGE>   19
prepare a supplement to the Prospectus to reflect the terms of the Preferred
Securities and the terms of the offering.  The Offerors will file the
Prospectus as so supplemented pursuant to Rule 424(b) under the Act not later
than the Commission's close of business on the second business day following
the execution and delivery of this Agreement, or, if applicable, such earlier
time as may be required by Rule 430A(a)(3) under the Act.

                          (c)  The Offerors will deliver to the Representative
as many signed copies of the Registration Statement as originally filed and of
each amendment thereto (including exhibits filed therewith or incorporated by
reference therein and documents incorporated or deemed to be incorporated by
reference therein) as the Representative may reasonably request and will also
deliver to the Representative a conformed copy of the Registration Statement as
originally filed and of each amendment thereto (without exhibits) for each of
the Underwriters.

                          (d)  The Offerors will furnish to each Underwriter,
from time to time during the period when the Prospectus is required to be
delivered under the 1933 Act, such number of copies of the Prospectus (as
amended or supplemented) as such Underwriter may reasonably request for the
purposes contemplated by the 1933 Act or the respective applicable rules and
regulations of the Commission thereunder.

                          (e)  If at any time when the Prospectus is required
by the 1933 Act to be delivered in connection with sales of the Preferred
Securities, any event shall occur as a result of which it is necessary, in the
opinion of counsel for the Underwriters or counsel to the Company and the
Trust, to amend or supplement the Prospectus in order to make the Prospectus
not misleading in the light of the circumstances existing at the time it is to
be delivered to a purchaser, or if it shall be necessary at any such time, to
amend the Registration Statement or amend or supplement the Prospectus in order
to comply with the requirements of the 1933 Act or the 1933 Act Regulation, the
Offerors will promptly prepare and file with the Commission subject to
paragraph (b) above such amendment or supplement as may be necessary to correct
such untrue statement or omission or to make the Registration Statement or the
Prospectus comply with such requirements; and the Offerors will furnish to the
Underwriters a reasonable number of copies of such amendment or supplement.

                          (f)  The Offerors will endeavor, in cooperation with
the Underwriters, to qualify the Preferred Securities (and the Preferred
Securities Guarantee) and the Subordinated Debt Securities for offering and
sale under the applicable securities laws of such states and the other
jurisdictions of the United States as the Representative may designate;
provided, however, that none of the Offerors shall be obligated to qualify as a
foreign corporation in any jurisdiction in which it is not so qualified.

                          (g)  The Trust will make generally available to its
security holders as soon as practicable but not later than 45 days after the
close of the period covered thereby, an earnings statement of the Company (in
form complying with the provisions of Rule 158 of the 1933 Act Regulations)
covering a twelve-month period beginning not later than the first day of the
Trust's fiscal quarter next following the "effective date" (as defined in said
Rule 158) of the Registration Statement.

                          (h)  For a period of five years after the Closing
Time, the Company will furnish to you and, upon request, to each Underwriter,
copies of all annual reports, quarterly reports and current reports filed with
the Commission on Forms 10-K, 10-Q and 8-K, or such other similar forms as may
be designated by the Commission, and such other documents, reports and
information as shall be furnished by the Company to its stockholders or
security holders generally.

                          (i)  The Offerors will use best efforts to effect the
listing of the Preferred Securities (including the Preferred Securities
Guarantee with respect thereto) on the New York Stock Exchange; if the
Preferred Securities are exchanged for Subordinated Debt Securities, the
Company will use its best efforts to effect the listing of the Subordinated
Debt Securities on the exchange on which the Preferred Securities were then
listed.

                          (j)  During a period of 30 days from the date of the
Pricing Agreement, neither the Trust nor the Company will, without the
Representative's prior written consent, directly or indirectly, sell, offer to
sell, grant any option for the sale of, or otherwise dispose of, any Preferred
Securities, any security convertible into or exchangeable into or exercisable
for Preferred Securities or the Subordinated Debt Securities or any debt
securities substantially similar to the Subordinated Debt Securities or equity
securities substantially similar to the Preferred Securities (except for the

         qualify or be in good standing would not have a material adverse
         effect on the Company and the Subsidiaries, considered as one

<PAGE>   28
         against the Company and each of the Regular Trustees in accordance
         with its terms, except to the extent that the enforcement thereof may
         be limited by the Bankruptcy Exceptions.

                                  (xxix)  To the best of his knowledge and
         information:  there are no legal or governmental proceedings pending
         or threatened that are required to be disclosed in the Registration
         Statement or Prospectus other than those disclosed therein, and all
         pending legal or governmental proceedings to which the Company, any of
         the Subsidiaries or the Trust is a party, or to which any of their
         property is subject, that are not described in the Registration
         Statement or Prospectus, including ordinary routine litigation
         incidental to the business, are, considered in the aggregate, not
         material.

                                  (xxx)  No authorization, approval, consent or
         order of any court or governmental authority or agency is required in
         connection with the issuance and sale of the Common Securities or the
         offering of the Preferred Securities, the Subordinated Debt Securities
         or the Guarantees, except (a) such as may be required under the 1933
         Act or the 1933 Act Regulations or state securities law, and (b) the
         qualification of the Declaration, the Preferred Securities Guarantee
         Agreement and the Indenture under the 1939 Act and 1939 Act
         Regulations.

                                  (xxxi) The execution, delivery and
         performance of this Agreement, the Pricing Agreement, the Declaration,
         the Preferred Securities, the Common Securities, the Indenture, the
         Subordinated Debt Securities, the Guarantee Agreements, and the
         Guarantees; the consummation of the transactions contemplated herein
         and therein; and the compliance by each of the Offerors with their
         respective obligations hereunder and thereunder do not and will not
         result in any violation of the charter or bylaws of the Company or any
         [Significant] Subsidiary or the Declaration or the Certificate of
         Trust, and do not and will not conflict with, or result in, a breach
         of any of the terms or provisions of, or constitute a default under,
         or result in the creation or imposition of any lien, charge or
         encumbrance upon any property or assets of the Trust or the Company or
         any [Significant] Subsidiary under (A) any contract, indenture,
         mortgage, loan agreement, note, lease or any other agreement or
         instrument known to such counsel to which the Trust or the Company or
         any [Significant] Subsidiary is a party or by which it





                                       28
<PAGE>   29
         may be bound or to which any of its properties may be subject (except
         for such conflicts, breaches or defaults or liens, charges or
         encumbrances that would not have a material adverse effect on the
         condition (financial or otherwise), earnings, business affairs or
         business prospects of the Trust or the Company and the [Significant]
         Subsidiaries, considered as one enterprise), (B) any existing
         applicable law, rule or regulation (other than the securities or blue
         sky laws of the various states, as to which such counsel need express
         no opinion) or (C) any judgment, order or decree of any government,
         governmental instrumentality or court, domestic or foreign, or any
         regulatory body or administrative agency or other governmental body
         having jurisdiction over the Trust, the Company or any [Significant]
         Subsidiary or any of their respective properties.

                                  (xxxii)  In addition, such counsel shall
         state that it has participated in conferences with officers and other
         representatives of the Offerors, representatives of the independent
         auditors for the Offerors and you and your counsel, at which
         conferences the contents of the Registration Statement, the Prospectus
         and related matters were discussed; such counsel has not independently
         verified the accuracy, completeness or fairness of the statements
         contained in the Registration Statement or the Prospectus, and the
         limitations inherent in the examination made by such counsel and the
         nature and extent of such counsel's participation in such conferences
         are such that such counsel is not passing upon, and is unable to
         assume and does not assume, any responsibility for, the accuracy,
         completeness or fairness of such statements, except as set forth in
         paragraph (xi) above with respect to statements made under the
         captions "Risk Factors," "The Trusts," "Phillips Capital Trust,"
         "Description of the Preferred Securities," "Description of the
         Preferred Securities Guarantees," "Description of the Guarantee,"
         "Description of the Subordinated Debt Securities" and "Effect of
         Obligations under the Subordinated Debt Securities and the Guarantee";
         however, based upon such counsel's participation in the aforesaid
         conferences, no facts have come to its attention that lead it to
         believe that the Registration Statement, and each amendment thereto,
         at the time it became effective, or if an annual report on Form 10-K
         has been filed by the Company with the Commission subsequent to the
         time of effectiveness of the Registration Statement and the Prospectus
         and





                                       29
<PAGE>   30
         any further amendments and supplements thereto made by the Offerors
         prior to the Closing Time (other than the financial statements and the
         notes thereto, the financial schedules, and the other financial and
         statistical data therein and the Statements of Eligibility on Forms
         T-1 of the Institutional Trustee, the Debt Trustee, and the Guarantee
         Trustee, as to which such counsel need express no belief) contained
         any untrue statements of a material fact or omitted to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading or that, as of its date, the
         Prospectus or any further amendments or sup- plements thereto made by
         the Company prior to the Closing Time (except as aforesaid) includes
         any untrue statement of a material fact or omits to state a material
         fact necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading or that, as
         of such Closing Time, either the Prospectus or any further supplements
         thereto made by the Company prior to such Closing Time (except as
         aforesaid) includes any untrue statement of a material fact or omits
         to state a material fact necessary to make the statements therein, in
         light of the circumstances under which they were made, not misleading.

                 Such opinion shall be to such further effect with respect to
         other legal matters relating to this Agreement and the sale of the
         Securities hereunder as counsel for the Underwriters may reasonably
         request.  In giving such opinion, such counsel may rely, as to all
         matters governed by the laws of jurisdictions other than the law of
         the District of Columbia, the federal law of the United States and the
         General Corporation Law and the Business Trust Act of the State of
         Delaware, upon opinions of other counsel, who shall be counsel
         satisfactory to counsel for the Underwriters, in which case the
         opinion shall state that they believe you and they are entitled to so
         rely.  In rendering the opinions required by paragraphs (xxi),
         (xxiii), (xxiv), (xxv), (xxvi), (xxvii), such counsel may assume that
         the laws of the State of New York are in effect substantially
         identical to the laws of the District of Columbia with respect to the
         matters covered by such opinions.  Such counsel may also state that,
         insofar as such opinion involves factual matters, they have relied, to
         the extent they deem proper, upon representations of officers of the
         Company and certificates of public officials; provided that such





                                       30
<PAGE>   31
         certificates have been delivered to the Underwriters.

                                  (2)      The favorable opinion, dated as of
Closing Time, of Emmet, Marvin & Martin, LLP, counsel of The Bank of New York,
as Institutional Trustee under the Declaration, and Guarantee Trustee under the
Preferred Securities Guarantee Agreements, and The Bank of New York (Delaware),
as Delaware Trustee under the Declaration, in form and substance satisfactory
to counsel for the Underwriters, to the effect that,

                                  (i)      The Bank of New York is a New York
         banking corporation with trust powers, duly organized, validly
         existing and in good standing under the laws of the State of New York
         with all necessary power and authority to execute and deliver, and to
         carry out and perform its obligations under the terms of the
         Declaration and the Preferred Securities Guarantee Agreement.

                                  (ii)     The Bank of New York (Delaware) is a
         Delaware banking corporation with trust powers, duly organized,
         validly existing and in good standing under the laws of the State of
         Delaware with all necessary power and authority to execute and
         deliver, and to carry out and perform its obligations under the terms
         of the Declaration.

                                  (iii)    The execution, delivery and
         performance by the Institutional Trustee and the Delaware Trustee of
         the Declaration and the execution, delivery and performance by the
         Guarantee Trustee of the Preferred Securities Guarantee Agreement have
         been duly authorized by all necessary corporate action on the part of
         the Institutional Trustee and the Delaware Trustee, in the case of the
         Declaration, and the Guarantee Trustee, in the case of the Preferred
         Securities Guarantee Agreement.  The Declaration and the Preferred
         Securities Guarantee Agreement have been duly executed and delivered
         by the Institutional Trustee and the Delaware Trustee, in the case of
         the Declaration, and the Guarantee Trustee, in the case of the
         Preerred Securities Guarantee Agreement, and constitute the legal,
         valid and binding obligations of the Institutional Trustee and the
         Delaware Trustee, in the case of the Declaration, and the Guarantee
         Trustee, in the case of the Preferred Securities Guarantee Agreement,
         enforceable against the Institutional Trustee and the Delaware
         Trustee, in the case of the Declaration, and the Guarantee Trustee, in
         the case of the Pre-





                                       31
<PAGE>   32
         ferred Securities Guarantee Agreement, in accordance with their terms,
         except as enforcement thereof may be limited by the Bankruptcy
         Exceptions.

                                  (iv)  The execution, delivery and performance
         of the Declaration and the Preferred Securities Guarantee Agreement by
         the Institutional Trustee and the Delaware Trustee, in the case of the
         Declaration, and the Guarantee Trustee, in the case of the Preferred
         Securities Guarantee Agreement, does not conflict with or constitute a
         breach of the Articles of Organization or Bylaws of the Institutional
         Trustee or the Delaware Trustee, in the case of the Declaration, or
         the Guarantee Trustee, in the case of the Preferred Securities
         Guarantee Agreement.

                                  (v)  No consent, approval or authorization
         of, or registration with or notice to, any New York, Delaware or
         federal banking authority is required for the execution, delivery or
         performance by the Institutional Trustee or the Delaware Trustee of
         the Declaration or by the Guarantee Trustee of the Preferred
         Securities Guarantee Agreement.

                                  (3)  The opinion of Skadden, Arps, Slate,
Meagher & Flom, special tax counsel to the Company and the Trust, generally to
the effect that:

                                  (i)  Under current law, the Trust will be
         classified for United States federal income tax purposes as a grantor
         trust and not as an association taxable as a corporation; accordingly,
         for United States federal income tax purposes, each holder of
         Preferred Securities generally will be considered the owner of an
         undivided interest in the Subordinated Debt Securities, and each
         holder will be required to include in its gross income any original
         issue discount accrued with respect to its allocable share of the
         Subordinated Debt Securities.

                                  (ii)  Although not entirely free from doubt,
         under current law the Subordinated Debt Securities will be classified
         for United States federal income tax purposes as indebtedness of the
         Company.

                                  (iii)  The discussion set forth in the
         Prospectus under the heading "United States Federal Income Taxation"
         is a fair and accurate summary of the matters addressed therein, based
         upon





                                       32
<PAGE>   33
         current law and the assumptions stated or referred to therein.

                 Such opinion may be conditioned on, among other things, the
initial and continuing accuracy of the facts, financial and other information,
covenants and representations set forth in certificates of officers of the
Company and the Trust and other documents deemed necessary for such opinion.

                                  (4)  The favorable opinion, dated as of
Closing Time, of Skadden, Arps, Slate, Meagher & Flom ("SASM&F"), counsel for
the Underwriters, in form and substance satisfactory to the Underwriters with
respect to the incorporation and legal existence of the Company; the legal
existence of the Trust, the Preferred Securities, the Indenture, the Preferred
Securities Guarantee Agreement, this Agreement, the Pricing Agreement, the
Registration Statement, the Prospectus and other related matters as the
Representative may require.

                 In giving its opinion, SASM&F may rely as to certain matters
of Delaware law upon the opinion of Dale J. Billam, Senior Counsel of the
Company, which shall be delivered in accordance with Section 5(b)(1) hereto,

                          (c)  At Closing Time, there shall not have been,
since the date hereof or since the respective dates as of which information is
given in the Registration Statement and the Prospectus, any material adverse
change in the condition, financial or otherwise, or in the earnings, business
affairs or business prospects of the Trust or the Company and its subsidiaries
considered as one enterprise, whether or not arising in the ordinary course of
business, and the Representative shall have received a certificate of a Vice
President of the Company and of the chief financial or chief accounting officer
of the Company and a certificate of a Regular Trustee of the Trust, and dated
as of Closing Time, to the effect that (i) there has been no such material
adverse change, (ii) the representations and warranties in Section 1 hereof are
true and correct with the same force and effect as though expressly made at and
as of Closing Time, (iii) the Trust and the Company have complied with all
agreements and satisfied all conditions on its part to be performed or
satisfied at or prior to Closing Time, and (iv) no stop order suspending the
effectiveness of the Registration Statement has been issued and no proceedings
for that purpose have been initiated or threatened by the Commission.

<PAGE>   34
                          (d)  At the time of the execution of this Agreement,
the Representative shall have received from Ernst & Young LLP a letter dated
such date, in form and substance satisfactory to the Representative, to the
effect that:

                                  (i) they are independent public accountants
         with respect to the Company and its consolidated subsidiaries, within
         the meaning of the 1933 Act and the 1933 Act Regulations;

                                  (ii) in their opinion, the consolidated
         financial statements and schedules audited (and, if applicable,
         prospective financial statements and/or pro forma financial
         information examined) by them and included or incorporated by
         reference in the Registration Statement or the Prospectus comply as to
         form in all material respects with the accounting requirements of the
         1933 Act or the Exchange Act, as applicable, and the related published
         rules and regulations thereunder, as applicable; they have made a
         review in accordance with standards established by the American
         Institute of Certified Public Accountants of the Company's
         consolidated interim financial statements as described in Statement on
         Auditing Standards ("SAS") No. 71, Interim Financial Information, for
         the periods specified in such letter performed at the request of the
         Company;

                                  (iii) based upon limited procedures set forth
         in detail in such letter, nothing has come to their attention which
         causes them to believe that

                                        (A) the unaudited consolidated
         financial statements of the Company included in the Registration
         Statement do not comply as to form in all material respects with the
         applicable accounting requirements of the 1934 Act and the 1934 Act
         Regulations, as they apply to Form 10-Q, or are not presented in
         conformity with generally accepted accounting principles applied on a
         basis substantially consistent with that of the audited financial
         statements included in the Registration Statement,

                                        (B) the unaudited amounts of revenues,
         net income and net income per share set forth under "Phillips
         Petroleum Company Summary Historical Financial Information" in the
         Prospectus were not determined on a basis substantially consistent
         with that used in determining the corresponding





                                       34
<PAGE>   35
         amounts in the audited financial statements included in the 
         Registration Statement, or

                                        (C) at a specified date not more than
         five days prior to the date of this Agreement, there has been any
         change in the capital stock of the Company and its subsidiaries or any
         increase in the consolidated long-term debt of the Company and its
         subsidiaries or any decrease total assets or net assets as compared
         with the amounts shown on the date of the most recent consolidated
         balance sheet included in or incorporated by reference in the
         Registration Statement and the Prospectus (________ ___, 1996 balance
         sheet included in the Registration Statement) or, during the period
         from the date of the most recent consolidated balance sheet included
         in or incorporated by reference in the Registration Statement and the
         Prospectus to a specified date not more than five days prior to the
         date of this Agreement, there were any decreases, as compared with the
         corresponding period in the preceding year, in operating revenues, net
         earnings available for common stock or net earnings per common share
         of the Company and its subsidiaries, except in all instances for
         changes, increases or decreases which the Registration Statement and
         the Prospectus disclose have occurred or may occur; and

                                  (iv)     in addition to the audit referred to
         in their opinions and the limited procedures referred to in clause
         (iii) above, they have carried out certain specified procedures, not
         constituting an audit, with respect to certain amounts, percentages
         and financial information which are included in the Registration
         Statement and Prospectus, or incorporated therein by reference, and
         which are specified by the Representative, and have found such
         amounts, percentages and financial information to be in agreement with
         the relevant accounting, financial and other records of the Company
         and its subsidiaries identified in such letter.

                          (e)  At Closing Time, the Representative shall have
received from Ernst & Young LLP a letter, dated as of Closing Time, to the
effect that they reaffirm the statements made in the letter furnished pursuant
to subsection (d) of this Section, except that the specified date referred to
shall be a date not more than five days prior to Closing Time.

                          (f)  At Closing Time and each Date of Delivery, if 
any, counsel for the Underwriters shall have





                                       35
<PAGE>   36
been furnished with such documents and opinions as they may require for the
purpose of enabling them to pass upon the issuance and sale of the Preferred
Securities as herein contemplated and related proceedings, or in order to
evidence the accuracy of any of the representations or warranties, or the
fulfillment of any of the conditions, herein contained; and all proceedings
taken by the Offerors, in connection with the issuance and sale of the
Preferred Securities as herein contemplated shall be satisfactory in form and
substance to the Representative and Skadden, Arps, Slate, Meagher & Flom,
counsel for the Underwriters.

                          (g)  At Closing Time, the Preferred Securities and
the Subordinated Debt Securities shall be rated in one of the four highest
rating categories for long term debt ("Investment Grade") by any nationally
recognized statistical rating agency, and the Trust shall have delivered to the
Representative a letter, dated the Closing Time, from such nationally
recognized statistical rating agency, or other evidence satisfactory to the
Representative, confirming that the Preferred Securities and the Subordinated
Debt Securities have Investment Grade ratings; and there shall not have
occurred any decrease in the ratings of any of the debt securities of the
Company or of the Preferred Securities by any "nationally recognized
statistical rating organization" (as defined for purposes of Rule 436(g) under
the Act) and such organization shall not have publicly announced that it has
under surveillance or review, with possible negative implications, its rating
of any of the debt securities of the Company or of the Preferred Securities.

                          (h)  At the Closing Time, the Preferred Securities
shall have been approved for listing on the New York Stock Exchange upon notice
of issuance.

                 If any condition specified in this Section shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be
terminated by the Representative by notice to the Offerors at any time at or
prior to Closing Time, and such termination shall be without liability of any
party to any other party except as provided in Section 4 hereof.

                 Section 6.  Indemnification

                          (a)  The Offerors agree to jointly and severally
indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of Section 15 of the 1933 Act as
follows:





                                       36
<PAGE>   37
                                  (i)      against any and all loss, liability,
         claim, damage and expense whatsoever, as incurred, arising out of any
         untrue statement or alleged untrue statement of a material fact
         contained in the Registration Statement (or any amendment thereto),
         including the information deemed to be part of the Registration
         Statement pursuant to Rule 430A(b) or Rule 434 of the 1933 Act
         Regulations, if applicable, or the omission or alleged omission
         therefrom of a material fact required to be stated therein or
         necessary to make the statements therein not misleading or arising out
         of any untrue statement or alleged untrue statement of a material fact
         contained in any preliminary prospectus or the Prospectus (or any
         amendment or supplement thereto) or the omission or alleged omission
         therefrom of a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading;

                                  (ii)  against any and all loss, liability,
         claim, damage and expense whatsoever, as incurred, to the extent of
         the aggregate amount paid in settlement of any litigation, or any
         investigation or proceeding by any govern-mental agency or body,
         commenced or threatened, or of any claim whatsoever based upon any
         such untrue statement or omission, or any such alleged untrue
         statement or omission, if such settlement is effected with the written
         consent of the Company; and

                                  (iii)  against any and all expense whatsoever
         as incurred (including, subject to Section 6(c) hereof, the fees and
         disbursements of counsel chosen by Merrill Lynch) reasonably incurred,
         in investigating, preparing or defending against any litigation, or
         any investigation or proceeding by any governmental agency or body,
         commenced or threatened, or any claim whatsoever based upon any such
         untrue statement or omission, to the extent that any such expense is
         not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written informa-





                                       37
<PAGE>   38
tion furnished to the Trust or the Company by any Underwriter through Merrill
Lynch expressly for use in the Registration Statement (or any amendment
thereto) or any preliminary prospectus or the Prospectus (or any amendment or
supplement thereto); and provided, further, that this indemnity agreement with
respect to any preliminary prospectus shall not inure to the benefit of any
underwriter from whom the person asserting any such losses, liabilities,
claims, damages or expenses purchased Securities, or any person controlling
such Underwriter, if the Offerors sustain the burden that a copy of the
Prospectus (as then amended or supplemented if the Company or the Trust shall
have furnished any such amendments or supplements thereto), but excluding
documents incorporated or deemed to be incorporated by reference, was not sent
or given by or on behalf of such Underwriter to such person, if such is
required by law, at or prior to the written confirmation of the sale of such
Securities to such person and if the Prospectus (as so amended or supplemented,
but excluding documents incorporated or deemed to be incorporated by reference
therein) would have corrected the defect giving rise to such loss, liability,
claim, damage or expense, it being understood that this proviso shall have no
application if such defect shall have been corrected in a document which is
incorporated or deemed to be incorporated by reference in the Prospectus.

                          (b)  The Company agrees to indemnify the Trust
against all loss, liability, claim, damage and expense whatsoever, as due from
the Trust under Section 6(a) hereunder.

                          (c)  Each Underwriter severally agrees to indemnify
and hold harmless the Offerors, their directors, trustees, each of its officers
who signed the Registration Statement, and each person, if any, who controls
the Offerors within the meaning of Section 15 of the 1933 Act against any and
all loss, liability, claim, damage and expense described in the indemnity
contained in subsection (a) of this Section, as incurred, but only with respect
to untrue statements or omissions, or alleged untrue statements or omissions,
made in the Registration Statement (or any amendment thereto) or any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Offerors by such Underwriter through Merrill Lynch expressly for use in
the Registration Statement (or any amendment thereto) or such preliminary
prospectus or the Prospectus (or any amendment or supplement thereto).

<PAGE>   39
                          (d)  Each indemnified party shall give notice as
promptly as reasonably practicable to each indemnifying party of any action
commenced against it in respect of which indemnity may be sought hereunder, but
failure to so notify an indemnifying party shall not relieve such indemnifying
party from any liability which it may have otherwise than on account of this
indemnity agreement.  An indemnifying party may participate at its  own expense
in the defense of any such action.  In no event shall the indemnifying parties
be liable for fees and expenses of more than one counsel (in addition to any
local counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in
the same jurisdiction arising out of the same general allegations or
circumstances.

                 Section 7.  Contribution.  In order to provide for just and
equitable contribution in circumstances in which the indemnity agreement
provided for in Section 6 hereof is for any reason held to be unenforceable by
the indemnified parties although applicable in accordance with its terms, the
Offerors and the Underwriters shall contribute to the aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by said
indemnity agreement incurred by the Offerors and one or more of the
Underwriters, as incurred, in such proportions that the Underwriters are
responsible for that portion represented by the percentage that the
underwriting compensation paid by the Company appearing on the cover page of
the Prospectus bears to the initial public offering price appearing thereon and
the Offerors are responsible for the balance; provided, however, that no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  For purposes of this Section,
each person, if any, who controls an Underwriter within the meaning of Section
15 of the 1933 Act shall have the same rights to contribution as such
Underwriter, and each director of the Company and each officer of the Company
who signed the Registration Statement, each trustee of the Trust and each
person, if any, who controls an Offeror within the meaning of Section 15 of the
1933 Act shall have the same rights to contribution as the Offerors.

                 Section 8.  Representations, Warranties and Agreements to
Survive Delivery.  All representations, warranties and agreements contained in
this Agreement and the Pricing Agreement, or contained in certificates of
officers or Trustees of the Offerors submitted pursuant





                                       39
<PAGE>   40
hereto, shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or controlling person, or
by or on behalf of the Offerors and shall survive delivery of the Preferred
Securities to the Underwriters.

                 Section 9.  Termination of Agreement.

                          (a)  The Representative may terminate this Agreement,
by notice to the Offerors, at any time at or prior to Closing Time (i) if there
has been, since the date of this Agreement or since the respective dates as of
which information is given in the Registration Statement, any material adverse
change in the condition financial or otherwise, or in the earnings, business
affairs or business prospects or the Trust or the Company and its subsidiaries
considered as one enterprise, whether or not arising in the ordinary course of
business, (ii) if there has occurred any material adverse change in the
financial markets in the United States or elsewhere or any outbreak of
hostilities or escalation thereof or other calamity or crisis the effect of
which is such as to make it, in the judgment of the Representative,
impracticable to market the Preferred Securities or to enforce contracts for
the sale of the Preferred Securities, (iii) if trading in the Preferred
Securities has been suspended by the Commission, or if trading generally on the
New York Stock Exchange has been suspended, limited or restricted or minimum or
maximum prices for trading have been fixed, or maximum ranges for prices for
securities have been required, by said exchange or by order of the Commission
or any other governmental authority, or if a banking moratorium has been
declared by either Federal, New York, [Oklahoma] or Delaware authorities or
(iv) if there has been any decrease in the ratings of any of the debt
securities of the Company or of the Preferred Securities by any "nationally
recognized statistical rating organization" (as defined for purposes of Rule
436(g) under the Act) or such organization shall have publicly announced that
it has under surveillance or review, with possible negative implications, its
rating of any of the debt securities of the Company or of the Preferred
Securities.

                          (b)  If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof.

                 Section 10.  Default by One or More of the Underwriters.  If
one or more of the Underwriters shall fail at Closing Time to purchase the
Preferred Securities that it or they are obligated to purchase under this
Agreement and the Pricing Agreement (the "Defaulted Securities"), the
Representative shall have the right, within 24 hours thereafter, to make
arrangements for one or more of the non-defaulting Underwriters, or any other
underwriters, to purchase all, but notthesDefaultedlSecurities in such amounts
as may be agreed upon and upon the terms herein set forth; if, however, the
Representatives shall not have completed such arrangements within such 24-hour
period, then:

                          (a)     if the number of Defaulted Securities does
         not exceed 10% of the Preferred Securities, each of the non-defaulting
         Underwriters shall be obligated, severally and not jointly, to
         purchase the full amount thereof in the proportions that their
         respective underwriting obligations hereunder bear to the underwriting
         obligations of all non-defaulting Underwriters, or

                          (b)     if the number of Defaulted Securities
         exceeds 10% of the Preferred Securities, this Agreement shall
         terminate without liability on the part of any non-defaulting
         Underwriter.

                 No action taken pursuant to this Section shall relieve any
defaulting Underwriter from liability in respect of its default.

                 In the event of any such default which does not result in a
termination of this Agreement, either the Representative or the Offerors shall
have the right to postpone Closing Time for a period not exceeding seven days
in order to effect any required changes in the Registration Statement or
Prospectus or in any other documents or arrangements.

                 Section 11.  Notices.  All notices and other communications
hereunder shall be in writing and shall be deemed to have been duly given if
mailed or transmitted by any standard form of telecommunication.  Notices to
the Underwriters shall be directed to the Representative at Merrill Lynch World
Headquarters, North Tower, World Financial Center, New York, New York
10281-1201, attention of [NAME], [TITLE]; notices to the Trust and the Company
shall be directed to them at Phillips Building, Bartlesville, Oklahoma 74004,

                 Section 12.  Parties.  This Agreement and the Pricing
Agreement shall each inure to the benefit of and be binding upon the
Underwriters and the Trust, the Company and their respective successors.
Nothing expressed or mentioned in this Agreement or the Pricing Agreement is
intended or shall be construed to give any person, firm or corporation, other
than the Underwriters and the Trust and the Company and their respective
successors and the controlling persons and officers, directors and trustees
referred to in Sections 6 and 7 and their heirs and legal representatives, any
legal or equitable right, remedy or claim under or in respect of this Agreement
or the Pricing Agreement or any provision herein or therein contained. This
Agreement and the Pricing Agreement and all conditions and provisions hereof
and thereof are intended to be for the sole and exclusive benefit of the
Underwriters and the Trust and the Company and their respective successors, and
said controlling persons and officers, directors and trustees and their heirs
and legal representatives, and for the benefit of no other person, firm or
corporation.  No purchaser of Securities from any Underwriter shall be deemed
to be a successor by reason merely of such purchase.

                 Section 13.  Governing Law and Time.  This Agreement and the
Pricing Agreement shall be governed by and construed in accordance with the
laws of the State of New York applicable to agreements made and to be performed
in said State.  Except as otherwise set forth herein, specified times of day
refer to New York City time.

                 Section 14.  Counterparts.  This Agreement may be executed by
any one or more of the parties hereto in any number of counterparts, each of
which shall be deemed to be an original, but all such respective counterparts
shall together constitute one and the same instrument.

Preferred Securities may, by vote, on behalf of the Holders of all of the

Event of Default under the Indenture:

                 (i)        is not waivable under the Indenture, the Event of
         Default under the Declaration shall also not be waivable; or

                 (ii)       requires the consent or vote of greater than a
         majority in principal amount of the holders of the Debentures (a
         "Super Majority") to be waived under the Indenture, the Event of
         Default under the Declaration may only be waived by the vote of the

Preferred Securities arising therefrom shall be deemed to have been cured, for
every purpose of this Declaration, but no such waiver shall extend to any
subsequent or other default or an Event of Default with respect to the
Preferred Securities or impair any right consequent thereon.  Any waiver by the
Holders of the Preferred Securities of an Event of Default with respect to the
Preferred Securities shall also be deemed to constitute a waiver by the Holders
of the Common Securities of any such Event of Default with respect to the
Common Securities for all purposes of this Declaration without any further act,
vote, or consent of the Holders of the Common Securities.

                 (b)        The Holders of a Majority in liquidation amount of
the Common Securities may, by vote, on behalf of the Holders of all of the

Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

                 (i)        is not waivable under the Indenture, except where
         the Holders of the Common Securities are deemed to have waived such
         Event of Default under the Declaration as provided below in this
         Section 2.6(b), the Event of Default under the Declaration shall also
         not be waivable; or

<PAGE>   16
                 (ii)       requires the consent or vote of a Super Majority to
         be waived, except where the Holders of the Common Securities are
         deemed to have waived such Event of Default under the Declaration as
         provided below in this Section 2.6(b), the Event of Default under the
         Declaration may only be waived by the vote of the Holders of at least
         the proportion in liquidation amount of the Common Securities that the
         relevant Super Majority represents of the aggregate principal amount
         of the Debentures outstanding;

provided further, each Holder of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default with respect to the
Common Securities and its consequences until all Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated,
and until such Events of Default have been so cured, waived or otherwise
eliminated, the Institutional Trustee will be deemed to be acting solely on
behalf of the Holders of the Preferred Securities and only the Holders of the
Preferred Securities will have the right to direct the Institutional Trustee in
accordance with the terms of the Securities.  The foregoing provisions of this
Section 2.6(b) shall be in lieu of Sections  316(a)(1)(A) and 316(a)(1)(B) of
the Trust Indenture Act and such Sections  316(a)(1)(A) and 316(a)(1)(B) of the
Trust Indenture Act are hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act.  Subject to the foregoing
provisions of this Section 2.6(b), upon such waiver, any such default shall
cease to exist and any Event of Default with respect to the Common Securities
arising therefrom shall be deemed to have been cured for every purpose of this
Declaration, but no such waiver shall extend to any subsequent or other default
or Event of Default with respect to the Common Securities or impair any right
consequent thereon.

                 (c)        A waiver of an Event of Default under the Indenture
by the Institutional Trustee at the direction of the Holders of the Preferred
Securities, constitutes a waiver of the corresponding Event of Default under
this Declaration.  The foregoing provisions of this Section 2.6(c) shall be in
lieu of Section  316(a)(1)(B) of the Trust Indenture Act and such Section
316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this
Declaration and the Securities, as permitted by the Trust Indenture Act.

SECTION 2.7      Event of Default; Notice.

                 (a)        The Institutional Trustee shall, within 90 days
after the occurrence of an Event of Default, transmit by mail, first class
postage prepaid, to the Holders of the Securities, notices of all defaults with
respect to the Securities actually known to a Responsible Officer of the
Institutional Trustee, unless such defaults have been cured before the giving
of such





                                       11
<PAGE>   17
notice (the term "defaults" for the purposes of this Section 2.7(a) being
hereby defined to be an Event of Default as defined in the Indenture, not
including any periods of grace provided for therein and irrespective of the
giving of any notice provided therein); provided that, except for a default in
the payment of principal of (or premium, if any) or interest on any of the
Debentures or in the payment of any sinking fund installment established for
the Debentures, the Institutional Trustee shall be protected in withholding
such notice if and so long as a Responsible Officer of the Institutional
Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders of the Securities.

                 (b)        The Institutional Trustee shall not be deemed to
have knowledge of any default except:

                 (i)        a default under Sections ____ and ____ of the
         Indenture; or

                 (ii)       any default as to which the Institutional Trustee
         shall have received written notice or of which a Responsible Officer
         of the Institutional Trustee charged with the administration of the
         Declaration shall have actual knowledge.

         Holders of Securities pursuant to the terms of this Declaration and of
         the Securities;





                                       16

SECTION 3.8      Powers and Duties of the Institutional Trustee.

                 (a)        The legal title to the Debentures shall be owned by

                 (i)        establish and maintain a segregated non-interest
         bearing trust account (the "Institutional Trustee Account")





                                       17
<PAGE>   23
         in the name of and under the exclusive control of the Institutional
         Trustee on behalf of the Holders of the Securities and, upon the
         receipt of payments of funds made in respect of the Debentures held by
         the Institutional Trustee, deposit such funds into the Institutional
         Trustee Account and make payments to the Holders of the Preferred
         Securities and Holders of the Common Securities from the Institutional
         Trustee Account in accordance with Section 6.1.  Funds in the
         Institutional Trustee Account shall be held uninvested until disbursed
         in accordance with this Declaration.  The Institutional Trustee
         Account shall be an account that is maintained with a banking
         institution the rating on whose long-term unsecured indebtedness is at
         least equal to the rating assigned to the Preferred Securities by a
         "nationally recognized statistical rating organization", as that term
         is defined for purposes of Rule 436(g)(2) under the Securities Act;

                 (ii)       engage in such ministerial activities as shall be
         necessary or appropriate to effect the redemption of the Preferred
         Securities and the Common Securities to the extent the Debentures are
         redeemed or mature; and

                 (iii)      upon written notice of distribution issued by the
         Regular Trustees in accordance with the terms of the Securities,
         engage in such ministerial activities as shall be necessary or
         appropriate to effect the distribution of the Debentures to Holders of
         Securities upon the occurrence of certain special events (as may be
         defined in the terms of the Securities) arising from a change in law
         or a change in legal interpretation or other specified circumstances
         pursuant to the terms of the Securities.

                 (d)        The Institutional Trustee shall take all actions
and perform such duties as may be specifically required of the Institutional
Trustee pursuant to the terms of the Securities.

                 (e)        The Institutional Trustee shall take any Legal
Action which arises out of or in connection with an Event of Default of which a
Responsible Officer of the Institutional Trustee has actual knowledge or the
Institutional Trustee's duties and obligations under this Declaration or the
Trust Indenture Act; provided however, that if a Declaration Event of Default
has occurred and is continuing and such event is attributable to the failure of
the Debenture Issuer to pay interest or principal on the Debentures on the date
such interest or principal is otherwise payable (or in the case of redemption,
on the redemption date), then a Holder of Preferred Securities may directly
institute a proceeding for enforcement of payment to such Holder of the
principal of or interest on the Debentures having a principal amount equal to
the aggregate liquidation amount of the Preferred Securities of such Holder (a
"Direct





                                       18
<PAGE>   24
Action") on or after the respective due date specified in the Debentures.  In
connection with such Direct Action, the rights of the Holders of the Common
Securities Holder will be subrogated to the rights of such Holder of Preferred
Securities to the extent of any payment made by the Issuer to such Holder of
Preferred Securities in such Direct Action.  Except as provided in the
preceding sentences, the Holders of Preferred Securities will not be able to
exercise directly any other remedy available to the holders of the Debentures.

                 (f)        The Institutional Trustee shall not resign as a
Trustee unless either:

                 (i)        the Trust has been completely liquidated and the
         proceeds of the liquidation distributed to the Holders of Securities
         pursuant to the terms of the Securities; or

                 (ii)       a Successor Institutional Trustee has been
         appointed and has accepted that appointment in accordance with Section
         5.7.

                 (g)        The Institutional Trustee shall have the legal
power to exercise all of the rights, powers and privileges of a holder of
Debentures under the Indenture and, if an Event of Default actually known to a
Responsible Officer of the Institutional Trustee occurs and is continuing, the
Institutional Trustee shall, for the benefit of Holders of the Securities,
enforce its rights as holder of the Debentures subject to the rights of the
Holders pursuant to the terms of such Securities.

                 (h)        The Institutional Trustee may authorize one or more
Persons (each, a "Paying Agent") to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all securities and
any such Paying Agent shall comply with Section  317(b) of the Trust Indenture
Act.  Any Paying Agent may be removed by the Institutional Trustee at any time
and a successor Paying Agent or additional Paying Agents may be appointed at
any time by the Institutional Trustee.

                 (i)        Subject to this Section 3.8, the Institutional
Trustee shall have none of the duties, liabilities, powers or the authority of
the Regular Trustees set forth in Section 3.6.

SECTION 3.9      Certain Duties and Responsibilities of the Institutional
                 Trustee.

                 (a)        The Institutional 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 Declaration and no implied covenants shall be read into this
Declaration against the Institutional Trustee.  In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6) of which a
Responsible Officer of the Institutional Trustee has actual knowledge, the
Institutional Trustee shall exercise such of the rights and powers vested in it
by this Declaration, 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 or her own affairs.

                 (b)        No provision of this Declaration shall be construed
to relieve the Institutional 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 an 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
                 Institutional Trustee shall be determined solely by the
                 express provisions of this Declaration and the Institutional
                 Trustee shall not be liable except for the performance of such
                 duties and obligations as are specifically set forth in this
                 Declaration, and no implied covenants or obligations shall be
                 read into this Declaration against the Institutional Trustee;
                 and

                            (B)     in the absence of bad faith on the part of
                 the Institutional Trustee, the Institutional 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 Institutional
                 Trustee and conforming to the requirements of this
                 Declaration; but in the case of any such certificates or
                 opinions that by any provision hereof are specifically
                 required to be furnished to the Institutional Trustee, the
                 Institutional Trustee shall be under a duty to examine the
                 same to determine whether or not they conform to the
                 requirements of this Declaration;

                 (ii)       the Institutional Trustee shall not be liable for
         any error of judgment made in good faith by a Responsible Officer of
         the Institutional Trustee, unless it shall be





                                       20
<PAGE>   26
         proved that the Institutional Trustee was negligent in ascertaining
         the pertinent facts;

                 (iii)      the Institutional 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 Securities relating to the time,
         method and place of conducting any proceeding for any remedy available
         to the Institutional Trustee, or exercising any trust or power
         conferred upon the Institutional Trustee under this Declaration;

                 (iv)       no provision of this Declaration shall require the
         Institutional Trustee to expend or risk its own funds or otherwise
         incur personal financial liability in the performance of any of its
         duties or in the exercise of any of its rights or powers, if it shall
         have reasonable grounds for believing that the repayment of such funds
         or liability is not reasonably assured to it under the terms of this
         Declaration or indemnity reasonably satisfactory to the Institutional
         Trustee against such risk or liability is not reasonably assured to
         it;

                 (v)        the Institutional Trustee's sole duty with respect
         to the custody, safe keeping and physical preservation of the
         Debentures and the Institutional Trustee Account shall be to deal with
         such property in a similar manner as the Institutional Trustee deals
         with similar property for its own account, subject to the protections
         and limitations on liability afforded to the Institutional Trustee
         under this Declaration and the Trust Indenture Act;

                 (vi)       the Institutional Trustee shall have no duty or
         liability for or with respect to the value, genuineness, existence or
         sufficiency of the Debentures or the payment of any taxes or
         assessments levied thereon or in connection therewith;

                 (vii)      the Institutional Trustee shall not be liable for
         any interest on any money received by it except as it may otherwise
         agree with the Sponsor.  Money held by the Institutional Trustee need
         not be segregated from other funds held by it except in relation to
         the Institutional Trustee Account maintained by the Institutional
         Trustee pursuant to Section 3.8(c)(i) and except to the extent
         otherwise required by law; and

                 (viii) the Institutional Trustee shall not be responsible for
         monitoring the compliance by the Regular Trustees or the Sponsor with
         their respective duties under this Declaration, nor shall the
         Institutional Trustee be liable for any

         Trustee, against the costs, expenses (including attorneys' fees and
         expenses and the expenses of the Institutional Trustee's agents,

         advances as may be requested by the Institutional Trustee provided,

         other evidence of indebtedness or other paper or document, but the

         compliance with any of the terms and provisions of this Declaration,
         both of which shall be conclusively evidenced by the Institutional
         Trustee's or its agent's taking such action;

                 (x)        whenever in the administration of this Declaration

                 (b)        The Trust may, with the consent of the Regular
Trustees or, if there are more than two, a majority of the Regular Trustees and
without the consent of the Holders of the Securities, the Delaware Trustee or
the Institutional Trustee, consolidate, amalgamate, merge with or into, or be
replaced by a trust organized as such under the laws of any State; provided
that:

                 (i)        such successor entity (the "Successor Entity")
         either:

                            (A)     expressly assumes all of the obligations of
                 the Trust under the Securities; or

                            (B)     substitutes for the 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 with respect to Distributions and payments
                 upon liquidation, redemption and otherwise;

         duties as the Institutional Trustee as the Holder of the Debentures;

                 (iii)      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

         or quoted;





                                       25
<PAGE>   31
                 (iv)       such merger, consolidation, amalgamation or
         replacement does not cause the Preferred Securities (including any
         Successor Securities) to be downgraded by any nationally recognized
         statistical rating organization;

                 (v)        such merger, consolidation, amalgamation or
         replacement does not adversely affect the rights, preferences and
         privileges of the Holders of the  Securities (including any Successor
         Securities) in any material respect (other than with respect to any
         dilution of such Holders' interests in the Preferred Securities as a
         result of such merger, consolidation, amalgamation or replacement);

                 (vi)       such Successor Entity has a purpose identical to
         that of the Trust;

                 (vii)      prior to such merger, consolidation, amalgamation
         or replacement, the Sponsor has received an opinion of a nationally
         recognized independent counsel to the Trust experienced in such
         matters to the effect that:

                            (A)     such merger, consolidation, amalgamation or
                 replacement does not adversely affect the rights, preferences
                 and privileges of the Holders of the Securities (including any
                 Successor Securities) in any material respect (other than with
                 respect to any dilution of the Holders' interest in the new
                 entity); and

                            (B)     following such merger, consolidation,
                 amalgamation or replacement, neither the Trust nor the
                 Successor Entity will be required to register as an Investment
                 Company;

                            (C)     following such merger, consolidation,
                 amalgamation or replacement, the Trust (or the Successor
                 Entity) will continue to be classified as a grantor trust for
                 United States federal income tax purposes; and

                 (viii) the Sponsor guarantees the obligations of such
         Successor Entity under the Successor Securities at least to the extent
         provided by the Preferred Securities Guarantees.

                 (c)        Notwithstanding Section 3.15(b), the Trust shall
not, except with the consent of Holders of 100% in liquidation amount of the
Securities, consolidate, amalgamate, merge with or into, or be replaced by any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger or
replacement would cause the Trust or Successor Entity to be classified as other
than a grantor trust for United States federal income tax purposes.

         Institutional Trustee shall be effective:

                            (A)     until a Successor Institutional Trustee has
                 been appointed and has accepted such appointment by instrument
                 executed by such Successor Institutional Trustee and delivered
                 to the Trust, the Sponsor and the resigning Institutional
                 Trustee; or

                            (B)     until the assets of the Trust have been
                 completely liquidated and the proceeds thereof distributed to

of an instrument of resignation, the resigning Institutional Trustee or
Delaware Trustee, as applicable, may petition any court of competent
jurisdiction for appointment of a Successor Institutional Trustee or Successor
Delaware Trustee.  Such court may thereupon, after prescribing such notice, if
any, as it may deem proper and prescribe, appoint a Successor Institutional
Trustee or Successor Delaware Trustee, as the case may be.

                 (f)        No Institutional Trustee or Delaware Trustee shall
be liable for the acts or omissions to act of any Successor Institutional

SECTION 5.8      Vacancies among Trustees.

                 If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 5.1, or if the number of
Trustees is increased pursuant to Section 5.1, a vacancy shall occur.  A
resolution certifying the existence of such vacancy by the Regular Trustees or,
if there are more than two, a majority of the Regular Trustees shall be
conclusive evidence of the existence of such vacancy.  The vacancy shall be
filled with a Trustee appointed in accordance with Section 5.7.

Trustee shall not operate to annul the Trust.  Whenever a vacancy in the number
of Regular Trustees shall occur, until such vacancy is filled by the
appointment of a Regular Trustee in accordance with Section 5.7, the Regular
Trustees in office, regardless of their number, shall have all the powers
granted to the Regular Trustees and shall discharge all the duties imposed upon
the Regular Trustees by this Declaration.

SECTION 5.10     Meetings.

                 If there is more than one Regular Trustee, meetings of the
Regular Trustees shall be held from time to time upon the call of any Regular
Trustee.  Regular meetings of the Regular Trustees may be held at a time and
place fixed by resolution of the Regular Trustees.  Notice of any in-person
meetings of the Regular Trustees shall be hand delivered or otherwise delivered
in writing (including by facsimile, with a hard copy by overnight courier) not
less than 48 hours before such meeting.  Notice of any telephonic meetings of
the Regular Trustees or any committee





                                       32
<PAGE>   38
thereof shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours before
a meeting.  Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting.  The presence (whether in person or by
telephone) of a Regular Trustee at a meeting shall constitute a waiver of
notice of such meeting except where a Regular Trustee attends a meeting for the
express purpose of objecting to the transaction of any activity on the ground
that the meeting has not been lawfully called or convened.  Unless provided
otherwise in this Declaration, any action of the Regular Trustees may be taken
at a meeting by vote of a majority of the Regular Trustees present (whether in
person or by telephone) and eligible to vote with respect to such matter,
provided that a Quorum is present, or without a meeting by the unanimous
written consent of the Regular Trustees.  In the event there is only one
Regular Trustee, any and all action of such Regular Trustee shall be evidenced
by a written consent of such Regular Trustee.

SECTION 5.11     Delegation of Power.

                 (a)        Any Regular 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 3.6, including any registration statement or amendment
thereto filed with the Commission, or making any other governmental filing; and

                 (b)        the Regular Trustees shall have power to delegate
from time to time to such of their number or to officers of the Trust the doing
of such things and the execution of such instruments either in the name of the
Trust or the names of the Regular Trustees or otherwise as the Regular Trustees
may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

Section 5.12     Merger, Conversion, Consolidation or Succession to Business.

         Any corporation into which the Institutional Trustee or the Delaware
Trustee, as the case may be, may be merged or converted or with which either
may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Institutional Trustee or the Delaware Trustee, as
the case may be, shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Institutional Trustee or
the Delaware Trustee, as the case may be, shall be the successor of the
Institutional Trustee or the Delaware Trustee, as the case may be, hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article,





                                       33

without the execution or filing of any paper or any further act on the part of
any of the parties hereto.

                                 DISTRIBUTIONS

SECTION 6.1      Distributions.

                 Holders shall receive Distributions (as defined herein) in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Preferred Securities and the Common
Securities in accordance with the preferences set forth in their respective
terms.  If and to the extent that the Debenture Issuer makes a payment of
interest (including Compounded Interest (as defined in the Indenture) and
Additional Interest (as defined in the Indenture)), premium and/or principal on
the Debentures held by the Institutional Trustee (the amount of any such
payment being a "Payment Amount"), the Institutional Trustee shall and is
directed, to the extent funds are available for that purpose, to make a
distribution (a "Distribution") of the Payment Amount to Holders.


                                  ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1      General Provisions Regarding Securities.

                 (a)        The Regular Trustees shall on behalf of the Trust
issue one class of preferred securities representing undivided beneficial
interests in the assets of the Trust having such terms as are set forth in
Annex I (the "Preferred Securities") and one class of common securities
representing undivided beneficial interests in the assets of the Trust having
such terms as are set forth in Annex I (the "Common Securities.")  The Trust
shall issue no securities or other interests in the assets of the Trust other
than the Preferred Securities and the Common Securities.

                 (b)        The Certificates shall be signed on behalf of the
Trust by a Regular Trustee.  Such signature shall be the manual signature of
any present or any future Regular Trustee.  In case any Regular Trustee of the
Trust who shall have signed any of the Securities shall cease to be such
Regular Trustee before the Certificates so signed shall be delivered by the
Trust, such Certificates nevertheless may be delivered as though the person who
signed such Certificates had not ceased to be such Regular Trustee; and any
Certificate may be signed on behalf of the Trust by such persons who, at the
actual date of execution of such Security, shall be the Regular Trustees of the
Trust, although at the date of the execution and delivery of the Decla-





                                       34
<PAGE>   40
ration any such person was not such a Regular Trustee.  Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Regular Trustees, as evidenced by their execution
thereof, and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements as the Regular Trustees may deem
appropriate, or as may be required to comply with any law or with any rule or
regulation of any stock exchange on which Securities may be listed, or to
conform to usage.

                 (c)        The consideration received by the Trust for the
issuance of the Securities shall constitute a contribution to the capital of
the Trust and shall not constitute a loan to the Trust.

                 (d)        Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable.

                 (e)        Every Person, by virtue of having become a Holder
or a Preferred Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration.

SECTION 7.2      Paying Agent.

                 In the event that the Preferred Securities are not in
book-entry only form, the Trust shall maintain in the Borough of Manhattan,
City of New York, State of New York, an office or agency where the Preferred
Securities may be presented for payment ("Paying Agent).  The Trust may appoint
the Paying Agent and may appoint one or more additional paying agents in such
other locations as it shall determine.  The term "Paying Agent" includes any
additional paying agent.  The Trust may change any Paying Agent without prior
notice to any Holder.  The Trust shall notify the Institutional Trustee of the
name and address of any Agent not a party to this Declaration.  If the Trust
fails to appoint or maintain another entity as Paying Agent, the Institutional
Trustee shall act as such.  The Trust or any of its Affiliates may act as
Paying Agent.  The Trust shall initially act as Paying Agent for the Preferred
Securities and the Common Securities.

         Securities;

                 (v)        upon the occurrence and continuation of a Special

         Securities in exchange for all of the Securities; or

         consent of all of the Regular Trustees and the Sponsor.

                 (b)        As soon as is practicable after the occurrence of
an event referred to in Section 8.1(a), the Trustees shall file a certificate
of cancellation with the Secretary of State of the State of Delaware.

                 (c)        The provisions of Section 3.9 and Article X shall
survive the termination of the Trust.

Certificates and of transfers of Certificates, which will be effected without
charge but only upon payment (with such indemnity as the Regular Trustees may
require) in respect of any tax or other government charges that may be imposed
in relation to it.  Upon surrender for registration of transfer of any
Certificate, the Regular Trustees shall cause one or more new Certificates to
be issued in the name of the designated transferee or transferees.  Every
Certificate surrendered for registration of transfer shall be accompanied by a
written instrument of transfer in form satisfactory to the Regular Trustees
duly executed by the Holder or such Holder's attorney duly authorized in
writing.  Each Certificate surrendered for registration of transfer shall be
canceled by the Regular Trustees.  A transferee of a Certificate shall be
entitled to the rights and subject to the obligations of a Holder hereunder
upon the receipt by such transferee of a Certificate.  By acceptance of a
Certificate, each transferee shall be deemed to have agreed to be bound by this
Declaration.

SECTION 9.3      Deemed Security Holders.

Certificate shall be registered on the books and records of the Trust as the

Certificate for purposes of receiving Distributions and for all other purposes
whatsoever and, accordingly, shall not be bound to recognize any equitable or
other claim to or interest in such Certificate or in the Securities represented
by such Certificate on the part of any Person, whether or not the Trust shall
have actual or other notice thereof.

SECTION 9.4      Book Entry Interests.

Securities, the Preferred Securities Certificates, on original issuance, will
be issued in the form of one or more, fully registered, global Preferred
Security Certificates (each a "Global Certificate"), to be delivered to DTC,
the initial Clearing Agency, by, or on behalf of, the Trust.  Such Global
Certificates shall initially be registered on the books and records of the
Trust in the name of Cede & Co., the nominee of DTC, and no Preferred Security
Beneficial Owner will receive a definitive





                                       37
<PAGE>   43
Preferred Security Certificate representing such Preferred Security Beneficial
Owner's interests in such Global Certifi- cates, except as provided in Section
9.7.  Unless and until definitive, fully registered Preferred Security
Certificates (the "Definitive Preferred Security Certificates") have been
issued to the Preferred Security Beneficial Owners pursuant to Section 9.7:

                 (a)        the provisions of this Section 9.4 shall be in full
         force and effect;

                 (b)        the Trust and the Trustees shall be entitled to
         deal with the Clearing Agency for all purposes of this Declaration
         (including the payment of Distributions on the Global Certificates and
         receiving approvals, votes or consents hereunder) as the Holder of the
         Preferred Securities and the sole holder of the Global Certificates
         and shall have no obligation to the Preferred Security Beneficial
         Owners;

                 (c)        to the extent that the provisions of this Section
         9.4 conflict with any other provisions of this Declaration, the
         provisions of this Section 9.4 shall control; and

                 (d)        the rights of the Preferred Security Beneficial
         Owners shall be exercised only through the Clearing Agency and shall
         be limited to those established by law and agreements between such
         Preferred Security Beneficial Owners and the Clearing Agency and/or
         the Clearing Agency Participants and receive and transmit payments of
         Distributions on the Global Certificates to such Clearing Agency
         Participants.  DTC will make book entry transfers among the Clearing
         Agency Participants.

SECTION 9.5      Notices to Clearing Agency.

                 Whenever a notice or other communication to the Preferred
Security Holders is required under this Declaration, unless and until
Definitive Preferred Security Certificates shall have been issued to the
Preferred Security Beneficial Owners pursuant to Section 9.7, the Regular
Trustees shall give all such notices and communications specified herein to be
given to the Preferred Security Holders to the Clearing Agency, and shall have
no notice obligations to the Preferred Security Beneficial Owners.

SECTION 9.6      Appointment of Successor Clearing Agency.

                 If any Clearing Agency elects to discontinue its services as
securities depositary with respect to the Preferred Securities, the Regular
Trustees may, in their sole discretion, appoint a successor Clearing Agency
with respect to such Preferred Securities.

SECTION 9.7      Definitive Preferred Security Certificates.

                 If:

                 (a)        a Clearing Agency elects to discontinue its
         services as securities depositary with respect to the Preferred
         Securities and a successor Clearing Agency is not appointed within 90
         days after such discontinuance pursuant to Section 9.6; or

                 (b)        the Regular Trustees elect after consultation with
         the Sponsor to terminate the book entry system through the Clearing
         Agency with respect to the Preferred Securities,

then:

                 (c)        Definitive Preferred Security Certificates shall be
         prepared by the Regular Trustees on behalf of the Trust with respect
         to such Preferred Securities; and

                 (d)        upon surrender of the Global Certificates by the
         Clearing Agency, accompanied by registration instructions, the Regular
         Trustees shall cause Definitive Certificates to be delivered to
         Preferred Security Beneficial Owners in accordance with the
         instructions of the Clearing Agency.  Neither the Trustees nor the
         Trust shall be liable for any delay in delivery of such instructions
         and each of them may conclusively rely on and shall be protected in
         relying on, said instructions of the Clearing Agency.  The Definitive
         Preferred Security Certificates shall be printed, lithographed or
         engraved or may be produced in any other manner as is reasonably
         acceptable to the Regular Trustees, as evidenced by their execution
         thereof, and may have such letters, numbers or other marks of
         identification or designation and such legends or endorsements as the
         Regular Trustees may deem appropriate, or as may be required to comply
         with any law or with any rule or regulation made pursuant thereto or
         with any rule or regulation of any stock exchange on which Preferred
         Securities may be listed, or to conform to usage.

SECTION 9.8      Mutilated, Destroyed, Lost or Stolen Certificates.

                 If:

                 (a)        any mutilated Certificates should be surrendered to
         the Regular Trustees, or if the Regular Trustees shall receive
         evidence to their satisfaction of the destruction, loss or theft of
         any Certificate; and





                                       39
<PAGE>   45
                 (b)        there shall be delivered to the Regular Trustees
         such security or indemnity as may be required by them to keep each of
         them harmless.

then, in the absence of notice that such Certificate shall have been acquired
by a bona fide purchaser, any Regular Trustee on behalf of the Trust shall
execute and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate of like denomination.
In connection with the issuance of any new Certificate under this Section 9.8,
the Regular Trustees 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 Certificate issued pursuant to this Section shall constitute
conclusive evidence of an ownership interest in the relevant Securities, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

                   HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1     Liability.

                 (a)        Except as expressly set forth in this Declaration,
the Securities Guarantees and the terms of the Securities, the Sponsor shall
not be:

                 (i)        personally liable for the return of any portion of
         the capital contributions (or any return thereon) of the Holders of
         the Securities which shall be made solely from assets of the Trust;
         and

                 (ii)       be required to pay to the Trust or to any Holder of
         Securities any deficit upon dissolution of the Trust or otherwise.

                 (b)        The Holder of the Common Securities shall be liable
for all of the debts and obligations of the Trust (other than with respect to
the Securities) to the extent not satisfied out of the Trust's assets.

                 (c)        Pursuant to Section  3803(a) of the Business Trust
Act, the Holders of the Preferred Securities 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.

SECTION 10.2     Exculpation.





                                       40
<PAGE>   46
                 (a)        No Indemnified Person shall be liable, responsible
or accountable in damages or otherwise to the Trust or any Covered Person for
any loss, damage or claim incurred by reason of 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 the authority conferred on such Indemnified Person by this Declaration or by
law, except that an Indemnified Person shall be liable for any such loss,
damage or claim incurred by reason of such Indemnified Person's gross
negligence or willful misconduct with respect to such acts or omissions.

                 (b)        An Indemnified Person shall be fully protected in
relying in good faith upon the records of the Trust and upon such information,
opinions, reports or statements presented to the Trust by any Person as to
matters the Indemnified Person reasonably believes are within such other
Person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any other facts pertinent to the existence and amount of
assets from which Distributions to Holders of Securities might properly be
paid.

SECTION 10.3     Fiduciary Duty.

                 (a)        To the extent that, at law or in equity, an
Indemnified Person has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to any other Covered Person, an Indemnified
Person acting under this Declaration shall not be liable to the Trust or to any
other Covered Person for its good faith reliance on the provisions of this
Declaration.  The provisions of this Declaration, to the extent that they
restrict the duties and liabilities of an Indemnified Person otherwise existing
at law or in equity (other than the duties imposed on the Institutional Trustee
under the Trust Indenture Act), are agreed by the parties hereto to replace
such other duties and liabilities of such Indemnified Person.

                 (b)        Unless otherwise expressly provided herein:

                 (i)        whenever a conflict of interest exists or arises
         between any Covered Persons; or

                 (ii)       whenever this Declaration or any other agreement
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such
action or provide such terms, considering in each case





                                       41
<PAGE>   47
the relative interest of each party (including its own interest) to such
conflict, agreement, transaction or situation and the benefits and burdens
relating to such interests, any customary or accepted industry practices, and
any applicable generally accepted accounting practices or principles.  In the
absence of bad faith by the Indemnified Person, the resolution, action or term
so made, taken or provided by the Indemnified Person shall not constitute a
breach of this Declaration or any other agreement contemplated herein or of any
duty or obligation of the Indemnified Person at law or in equity or otherwise.

                 (c)        Whenever in this Declaration an Indemnified Person
is permitted or required to make a decision:

                 (i)        in its "discretion" or under a grant of similar
         authority, the Indemnified Person shall be entitled to consider such
         interests and factors as it desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

                 (ii)       in its "good faith" or under another express
         standard, the Indemnified Person shall act under such express standard
         and shall not be subject to any other or different standard imposed by
         this Declaration or by applicable law.

SECTION 10.4     Indemnification.

                 (a) (i)   The Debenture Issuer shall indemnify, to the full
extent permitted by law, any Company Indemnified Person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Trust) by reason
of the fact that he is or was a Company Indemnified Person against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Trust, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful.  The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the Company
Indemnified Person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the Trust,
and, with respect to any criminal action or proceeding, had reasonable cause to
believe that his conduct was unlawful.





                                       42
<PAGE>   48
                 (ii)       The Debenture Issuer shall indemnify, to the full
         extent permitted by law, any Company Indemnified Person who was or is
         a party or is threatened to be made a party to any threatened, pending
         or completed action or suit by or in the right of the Trust to procure
         a judgment in its favor by reason of the fact that he is or was a
         Company Indemnified Person against expenses (including attorneys'
         fees) actually and reasonably incurred by him in connection with the
         defense or settlement of such action or suit if he acted in good faith
         and in a manner he reasonably believed to be in or not opposed to the
         best interests of the Trust and except that no such indemnification
         shall be made in respect of any claim, issue or matter as to which
         such Company Indemnified Person shall have been adjudged to be liable
         to the Trust unless and only to the extent that the Court of Chancery
         of Delaware or the court in which such action or suit was brought
         shall determine upon application that, despite the adjudication of
         liability but in view of all the circumstances of the case, such
         person is fairly and reasonably entitled to indemnity for such
         expenses which such Court of Chancery or such other court shall deem
         proper.

                 (iii)      To the extent that a Company Indemnified Person
         shall be successful on the merits or otherwise (including dismissal of
         an action without prejudice or the settlement of an action without
         admission of liability) in defense of any action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 10.4(a), or in
         defense of any claim, issue or matter therein, he shall be
         indemnified, to the full extent permitted by law, against expenses
         (including attorneys' fees) actually and reasonably incurred by him in
         connection therewith.

                 (iv)       Any indemnification under paragraphs (i) and (ii)
         of this Section 10.4(a) (unless ordered by a court) shall be made by
         the Debenture Issuer only as authorized in the specific case upon a
         determination that indemnification of the Company Indemnified Person
         is proper in the circumstances because he has met the applicable
         standard of conduct set forth in paragraphs (i) and (ii).  Such
         determination shall be made (1) by the Regular Trustees by a majority
         vote of a quorum consisting of such Regular Trustees who were not
         parties to such action, suit or proceeding, (2) if such a quorum is
         not obtainable, or, even if obtainable, if a quorum of disinterested
         Regular Trustees so directs, by independent legal counsel in a written
         opinion, or (3) by the Common Security Holder of the Trust.

                 (v)        Expenses (including attorneys' fees) incurred by a
         Company Indemnified Person in defending a civil, criminal,
         administrative or investigative action, suit or proceeding referred to
         in paragraphs (i) and (ii) of this Section





                                       43
<PAGE>   49
         10.4(a) shall be paid by the Debenture Issuer in advance of the final
         disposition of such action, suit or proceeding upon receipt of an
         undertaking by or on behalf of such Company Indemnified Person to
         repay such amount if it shall ultimately be determined that he is not
         entitled to be indemnified by the Debenture Issuer as authorized in
         this Section 10.4(a).  Notwithstanding the foregoing, no advance shall
         be made by the Debenture Issuer if a determination is reasonably and
         promptly made (i) by the Regular Trustees by a majority vote of a
         quorum of disinterested Regular Trustees, (ii) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Regular Trustees so directs, by independent legal counsel in a written
         opinion or (iii) the Common Security Holder of the Trust, that, based
         upon the facts known to the Regular Trustees, counsel or the Common
         Security Holder at the time such determination is made, such Company
         Indemnified Person acted in bad faith or in a manner that such person
         did not believe to be in or not opposed to the best interests of the
         Trust, or, with respect to any criminal proceeding, that such Company
         Indemnified Person believed or had reasonable cause to believe his
         conduct was unlawful.  In no event shall any advance be made in
         instances where the Regular Trustees, independent legal counsel or
         Common Security Holder reasonably determine that such person
         deliberately breached his duty to the Trust or its Common or Preferred
         Security Holders.

                 (vi)       The indemnification and advancement of expenses
         provided by, or granted pursuant to, the other paragraphs of this
         Section 10.4(a) shall not be deemed exclusive of any other rights to
         which those seeking indemnification and advancement of expenses may be
         entitled under any agreement, vote of stockholders or disinterested
         directors of the Debenture Issuer or Preferred Security Holders of the
         Trust or otherwise, both as to action in his official capacity and as
         to action in another capacity while holding such office.  All rights
         to indemnification under this Section 10.4(a) shall be deemed to be
         provided by a contract between the Debenture Issuer and each Company
         Indemnified Person who serves in such capacity at any time while this
         Section 10.4(a) is in effect.  Any repeal or modification of this
         Section 10.4(a) shall not affect any rights or obligations then
         existing.

                 (vii)      The Debenture Issuer or the Trust may purchase and
         maintain insurance on behalf of any person who is or was a Company
         Indemnified Person against any liability asserted against him and
         incurred by him in any such capacity, or arising out of his status as
         such, whether or not the Debenture Issuer would have the power to
         indemnify him against such liability under the provisions of this
         Section 10.4(a).

<PAGE>   50
                 (viii)     For purposes of this Section 10.4(a), references to
         "the Trust" shall include, in addition to the resulting or surviving
         entity, any constituent entity (including any constituent of a
         constituent) absorbed in a consolidation or merger, so that any person
         who is or was a director, trustee, officer or employee of such
         constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee or agent
         of another entity, shall stand in the same position under the
         provisions of this Section 10.4(a) with respect to the resulting or
         surviving entity as he would have with respect to such constituent
         entity if its separate existence had continued.

                 (ix)       The indemnification and advancement of expenses
         provided by, or granted pursuant to, this Section 10.4(a) shall,
         unless otherwise provided when authorized or ratified, continue as to
         a person who has ceased to be a Company Indemnified Person and shall
         inure to the benefit of the heirs, executors and administrators of
         such a person.

                 (b)        The Debenture Issuer agrees to indemnify the (i)
Institutional Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the
Institutional Trustee and the Delaware Trustee, and (iv) any officers,
directors, shareholders, members, partners, employees, representatives,
custodians, nominees or agents of the Institutional Trustee and the Delaware
Trustee (each of the Persons in (i) through (iv) being referred to as a
"Fiduciary Indemnified Person") for, and to hold each Fiduciary Indemnified
Person harmless against, any loss, liability or expense incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration or the trust or trusts hereunder, including the
costs and expenses (including reasonable legal fees and expenses) of defending
itself against or investigating any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder.  The
obligation to indemnify as set forth in this Section 10.4(b) shall survive the
satisfaction and discharge of this Declaration.

SECTION 10.5     Outside Businesses.

                 Any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional Trustee may 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
Securities shall have no rights by virtue of this Declaration 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.  No Covered Person, the
Sponsor, the Delaware Trustee, or the Institutional Trustee shall be obligated
to pres-





                                       45
<PAGE>   51
ent 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 any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional 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 Covered Person, the Delaware
Trustee and the Institutional Trustee may engage or be interested in any
financial or other transaction with the Sponsor or any Affiliate of the
Sponsor, or may act as depositary for, trustee or agent for, or act on any
committee or body of holders of, securities or other obligations of the Sponsor
or its Affiliates.

                                   ACCOUNTING

SECTION 11.1     Fiscal Year.

                 The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

SECTION 11.2     Certain Accounting Matters.

                 (a)        At all times during the existence of the Trust, the
Regular Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail,
each transaction of the Trust.  The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied.  The Trust shall use the accrual method of
accounting for United States federal income tax purposes.  The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year of the Trust by a firm of independent certified public
accountants selected by the Regular Trustees.

                 (b)        The Regular Trustees shall cause to be prepared and
delivered to each of the Holders of Securities, within 90 days after the end of
each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss;

                 (c)        The Regular Trustees shall cause to be duly
prepared and delivered to each of the Holders of Securities, any annual United
States federal income tax information statement, required by the Code,
containing such information with regard to the Securities held by each Holder
as is required by the Code and the Treasury Regulations.  Notwithstanding any
right under the Code to deliver any such statement at a later date, the Regular





                                       46
<PAGE>   52
Trustees shall endeavor to deliver all such statements within 30 days after the
end of each Fiscal Year of the Trust.

                 (d)        The Regular Trustees shall cause to be duly
prepared and filed with the appropriate taxing authority, an annual United
States federal income tax return, on a Form 1041 or such other form required by
United States federal income tax law, and any other annual income tax returns
required to be filed by the Regular Trustees on behalf of the Trust with any
state or local taxing authority.

SECTION 11.3     Banking.

                 The Trust shall maintain one or more bank accounts in the name
and for the sole benefit of the Trust; provided, however, that all payments of
funds in respect of the Debentures held by the Institutional Trustee shall be
made directly to the Institutional Trustee Account and no other funds of the
Trust shall be deposited in the Institutional Trustee Account.  The sole
signatories for such accounts shall be designated by the Regular Trustees;
provided, however, that the Institutional Trustee shall designate the
signatories for the Institutional Trustee Account.

SECTION 11.4     Withholding.

                 The Trust and the Regular Trustees shall comply with all
withholding requirements under United States federal, state and local law.  The
Trust shall request, and the Holders shall provide to the Trust, such forms or
certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably
be requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations.  The Regular Trustees shall file
required forms with applicable jurisdictions and, unless an exemption from
withholding is properly established by a Holder, shall remit amounts withheld
with respect to the Holder to applicable jurisdictions.  To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to distributions or allocations to any Holder, the amount withheld

withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

SECTION 12.2     Meetings of the Holders of Securities; Action by Written
                 Consent.

                 (a)        Meetings of the Holders of any class of Securities
may be called at any time by the Regular Trustees (or as provided in the terms
of the Securities) to consider and act on any matter on which Holders of such
class of Securities are entitled to act under the terms of this Declaration,
the terms of the Securities or the rules of any stock exchange on which the
Preferred Securities are listed or admitted for trading.  The Regular Trustees
shall call a meeting of the Holders of such class if directed to do so by the
Holders of at least 10% in liquidation amount of such class of Securities.
Such direction shall be given by delivering to the Regular Trustees one or more
calls in a writing stating that the signing Holders of Securities wish to call
a meeting and indicating the general or specific purpose for which the meeting
is to be called.  Any Holders of Securities calling a meeting shall specify in
writing the Security Certificates held by the Holders of Securities exercising
the right to call a meeting and only those Securities specified shall be
counted for purposes of determining whether the required percentage set forth
in the second sentence of this paragraph has been met.

                 (b)        Except to the extent otherwise provided in the
terms of the Securities, the following provisions shall apply to meetings of
Holders of Securities:

                 (i)        notice of any such meeting shall be given to all
         the Holders of Securities having a right to vote thereat at least 7
         days and not more than 60 days before the date of such meeting.
         Whenever a vote, consent or approval of the Holders of Securities is
         permitted or required under this Declaration or the rules of any stock
         exchange on which the Preferred Securities are listed or admitted for
         trading, such vote, consent or approval may be given at a meeting of
         the Holders of Securities.  Any action that may be taken at a meeting
         of the Holders of Securities may be taken without a meeting if a
         consent in writing setting forth the action so taken is signed by the
         Holders of Securities owning not less than the minimum amount of
         Securities in liquidation amount that would be necessary to authorize
         or take such action at a meeting at which all Holders of Securities
         having a right to vote thereon were present and voting.  Prompt notice
         of the taking of action without a meeting shall be given to the
         Holders of Securities entitled to vote who have not consented in
         writing.  The Regular Trustees may specify that any written ballot
         submitted to the Security Holder for the purpose of taking any action
         without a meeting shall be returned to the Trust within the time
         specified by the Regular Trustees;

                 (ii)       each Holder of a Security may authorize any Person
         to act for it by proxy on all matters in which a Holder of Securities
         is entitled to participate, including waiving notice of any meeting,
         or voting or participating at a meeting.  No proxy shall be valid
         after the expiration of 11 months from the date thereof unless
         otherwise provided in the proxy.  Every proxy shall be revocable at
         the pleasure of the Holder of Securities executing it.  Except as
         otherwise provided herein, all matters relating to the giving, voting
         or validity of proxies shall be governed by the General Corporation
         Law of the State of Delaware relating to proxies, and judicial
         interpretations thereunder, as if the Trust were a Delaware
         corporation and the Holders of the Securities were stockholders of a
         Delaware corporation;

                 (iii)      each meeting of the Holders of the Securities shall
         be conducted by the Regular Trustees or by such other Person that the
         Regular Trustees may designate; and

                 (iv)       unless the Business Trust Act, this Declaration,
         the terms of the Securities, the Trust Indenture Act or the listing
         rules of any stock exchange on which the Preferred Securities are then
         listed or trading, otherwise provides, the Regular Trustees, in their
         sole discretion, shall establish all other provisions relating to
         meetings of Holders of Securities, including notice of the time, place
         or purpose of any meeting at which any matter is to be voted on by any
         Holders of Securities, waiver of any such notice, action by consent
         without a meeting, the establishment of a record date, quorum
         requirements, voting in person or by proxy or any other matter with
         respect to the exercise of any such right to vote.

                                    ANNEX I


                                    TERMS OF
                   ___% TRUST ORIGINATED PREFERRED SECURITIES
                    ___% TRUST ORIGINATED COMMON SECURITIES


                 Pursuant to Section 7.1 of the Amended and Restated
Declaration of Trust, dated as of _______, 1996 (as amended from time to time,
the "Declaration"), the designation, rights, privileges, restrictions,
preferences and other terms and provisions of the Preferred Securities and the
Common Securities are set out below (each capitalized term used but not defined
herein has the meaning set forth in the Declaration or, if not defined in such
Declaration, as defined in the Prospectus referred to below):

                 1.       Designation and Number.

                 (a)      Preferred Securities.  [                ] Preferred
Securities of the Trust with an aggregate liquidation amount with respect to
the assets of the Trust of [             ] dollars ($[            ]) and a
liquidation amount with respect to the assets of the Trust of $25 per preferred
security, are hereby designated for the purposes of identification only as
"_____% Trust Originated Preferred SecuritiesSM ('TOPrS'SM)" (the "Preferred
Securities").  The Preferred Security Certificates evidencing the Preferred
Securities shall be substantially in the form of Exhibit A-1 to the
Declaration, with such changes and additions thereto or deletions therefrom as
may be required by ordinary usage, custom or practice or to conform to the
rules of any stock exchange on which the Preferred Securities are listed.

                 (b)      Common Securities.  [               ] Common
Securities of the Trust with an aggregate liquidation amount with respect to
the assets of the Trust of [               ] dollars ($[           ]) and a
liquidation amount with respect to the assets of the Trust of $25 per common
security, are hereby designated for the purposes of identification only as
"______% Trust Originated Common Securities" (the "Common Securities").  The
Common Security Certificates evidencing the Common Securities shall be
substantially in the form of Exhibit A-2 to the Declara- tion, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice.

                 2.       Distributions.

                 (a)      Distributions payable on each Security will be fixed
at a rate per annum of ______% (the "Coupon Rate") of the stated liquidation
amount of $25 per Security, such rate being





                                      I-1
<PAGE>   63
the rate of interest payable on the Debentures to be held by the Institutional
Trustee.  Distributions in arrears for more than one quarter will bear interest
thereon compounded quarterly at the Coupon Rate (to the extent permitted by
applicable law).  The term "Distributions" as used herein includes such cash
distributions and any such interest payable unless otherwise stated.  A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Institutional Trustee and to the extent the
Institutional Trustee has funds available therefor.  The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 90-day quarter.

                 (b)      Distributions on the Securities will be cumulative,
will accrue from ________, 1996, and will be payable quarterly in arrears, on
[March 31, June 30, September 30, and December 31] of each year, commencing on
[June 30,] 1996, except as otherwise described below.  The Debenture Issuer has
the right under the Indenture to defer payments of interest by extending the
interest payment period from time to time on the Debentures for a period not
exceeding 20 consecutive quarters or extend beyond the maturity date of the
Debentures (each an "Extension Period"), during which Extension Period no
interest shall be due and payable on the Debentures, provided that no Extension
Period shall last beyond the date of maturity of the Debentures.  As a
consequence of such deferral, Distributions will also be deferred.  Despite
such deferral, quarterly Distributions will continue to accrue with interest
thereon (to the extent permitted by applicable law) at the Coupon Rate
compounded quarterly during any such Extension Period.  Prior to the
termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters or extend beyond the maturity of the Debentures.  Payments of accrued
Distributions will be payable to Holders as they appear on the books and
records of the Trust on the first record date after the end of the Extension
Period.  Upon the termination of any Extension Period and the payment of all
amounts then due, the Debenture Issuer may commence a new Extension Period,
subject to the above requirements.

                 (c)      Distributions on the Securities will be payable to
the Holders thereof as they appear on the books and records of the Trust on the
relevant record dates.  While the Preferred Securities remain in book-entry
only form, the relevant record dates shall be one Business Day prior to the
relevant payment dates which payment dates correspond to the interest payment
dates on the Debentures.  Subject to any applicable laws and





                                      I-2
<PAGE>   64
regulations and the provisions of the Declaration, each such payment in respect
of the Preferred Securities will be made as described under the heading
"Description of the Preferred Securities -- Book-Entry Only Issuance -- The
Depository Trust Company" in the Prospectus Supplement dated______, 1996, to
the Prospectus dated ______, 1996 (together, the "Prospectus"), of the Trust
included in the Registration Statement on Form S-3 of the Sponsor, the Trust
and certain other business trusts.  The relevant record dates for the Common
Securities shall be the same record date as for the Preferred Securities.  If
the Preferred Securities shall not continue to remain in book-entry only form,
the relevant record dates for the Preferred Securities, shall conform to the
rules of any securities exchange on which the securities are listed and, if
none, shall be selected by the Regular Trustees, which dates shall be at least
one Business Day but less than 60 Business Days before the relevant payment
dates, which payment dates correspond to the interest payment dates on the
Debentures.  Distributions payable on any Securities that are not punctually
paid on any Distribution payment date, as a result of the Debenture Issuer
having failed to make a payment under the Debentures, will cease to be payable
to the Person in whose name such Securities are registered on the relevant
record date, and such defaulted Distribution will instead be payable to the
Person in whose name such Securities are registered on the special record date
or other specified date determined in accordance with the Indenture.  If any
date on which Distributions are payable on the Securities is not a Business
Day, then payment of the Distribution 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 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 such date.

                 (d)      In the event that there is any money or other
property held by or for the Trust that is not accounted for hereunder, such
property shall be distributed Pro Rata (as defined herein) among the Holders of
the Securities.

                 3.       Liquidation Distribution Upon Dissolution.

                 In the event of any voluntary or involuntary dissolution,
winding-up or termination of the Trust, the Holders of the Securities on the
date of the dissolution, winding-up or termination, as the case may be, will be
entitled to receive out of the assets of the Trust available for distribution
to Holders of Securities after satisfaction of liabilities of creditors an
amount equal to the aggregate of the stated liquidation amount of $25 per
Security plus accrued and unpaid Distributions thereon to the date of payment
(such amount being the "Liquidation Distribution"), unless, in connection with
such dissolution, winding-up or termination, Debentures in an aggregate stated
principal





                                      I-3
<PAGE>   65
amount equal to the aggregate stated liquidation amount of such Securities,
with an interest rate equal to the Coupon Rate of, and bearing accrued and
unpaid interest in an amount equal to the accrued and unpaid Distributions on,
such Securities, shall be distributed on a Pro Rata basis to the Holders of the
Securities in exchange for such Securities.

                 If, upon any such dissolution, 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 the Securities shall be paid on a Pro Rata basis.

                 4.       Redemption and Distribution.

                 (a)      Upon the repayment of the Debentures in whole or in
part, whether at maturity or upon redemption (either at the option of the
Debenture Issuer or pursuant to a Tax Event as described below), the proceeds
from such repayment or payment shall be simultaneously applied to redeem
Securities having an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so repaid or redeemed at a redemption price
of $25 per Security plus an amount equal to accrued and unpaid Distributions
thereon at the date of the redemption, payable in cash (the "Redemption
Price").  Holders will be given not less than 30 nor more than 60 days notice
of such redemption.

                 (b)      If fewer than all the outstanding Securities are to
be so redeemed, the Common Securities and the Preferred Securities will be
redeemed Pro Rata and the Preferred Securities to be redeemed will be as
described in Section 4(f)(ii) below.

                 (c)      If, at any time, a Tax Event (as defined below) shall
occur and be continuing the Regular Trustees shall, except in certain limited
circumstances described in this Section 4(c), dissolve the Trust and, after
satisfaction of creditors, cause Debentures held by the Institutional Trustee,
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the Coupon Rate of, and accrued
and unpaid interest equal to accrued and unpaid Distributions on, and having
the same record date for payment as the Securities, to be distributed to the
Holders of the Securities in liquidation of such Holders' interests in the
Trust on a Pro Rata basis, within 90 days following the occurrence of such Tax
Event (the "90 Day Period"); provided, however, that, as a condition of such
dissolution and distribution, the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "No Recognition Opinion"), which opinion may rely on published
revenue rulings of the Internal Revenue Service, to the effect that the Holders
of the Securities will not recognize any gain or loss for United States federal
income tax purposes as a result of the dissolution of the





                                      I-4
<PAGE>   66
Trust and the distribution of Debentures, and provided, further, that, if at
the time there is available to the Trust the opportunity to eliminate, within
the 90 Day Period, the Tax Event by taking some ministerial action, such as
filing a form or making an election, or pursuing some other similar reasonable
measure that has no adverse effect on the Trust, the Debenture Issuer, the
Sponsor or the Holders of the Securities ("Ministerial Action"), the Trust will
pursue such Ministerial Action in lieu of dissolution.

                 If in the event of a Tax Event, (i) after receipt of a Tax
Event Opinion (as defined hereinafter) by the Regular Trustees, the Debenture
Issuer has received an opinion (a "Redemption Tax Opinion") of a nationally
recognized independent tax counsel experienced in such matters that, as a
result of a Tax Event, there is more than an insubstantial risk that the
Debenture Issuer would be precluded from deducting the interest on the
Debentures for United States federal income tax purposes even after the
Debentures were distributed to the Holders of Securities in liquidation of such
Holders' interests in the Trust as described in this Section 4(c), or (ii) the
Regular Trustees shall have been informed by such tax counsel that a No
Recognition Opinion cannot be delivered to the Trust, the Debenture Issuer
shall have the right at any time, upon not less than 30 nor more than 60 days
notice, to redeem the Debentures in whole or in part for cash within 90 days
following the occurrence of such Tax Event, and, following such redemption,
Securities with an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so redeemed shall be redeemed by the Trust
at the Redemption Price on a Pro Rata basis; provided, however, that, if at the
time there is available to the Debenture Issuer or the Trust the opportunity to
eliminate, within such 90 day period, the Special Event by taking some
Ministerial Action, the Trust or the Debenture Issuer will pursue such
Ministerial Action in lieu of redemption.

                 "Tax Event" means that the Regular Trustees shall have
received an opinion of a nationally recognized independent tax counsel
experienced in such matters (a "Dissolution Tax Opinion") to the effect that on
or after the date of the Prospectus Supplement, as a result of (a) any
amendment to, clarification of 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 affecting
taxation, (b) any judicial decision, official adminis- trative pronouncement,
ruling, regulatory procedure, notice or announcement, including any notice or
announcement of intent to adopt such procedures or regulations (an
"Administrative Action") or (c) any amendment to, clarification of, or change
in the official position or the interpretation of such Administrative Action or
judicial decision that differs from the theretofore generally accepted
position, in each case, by any legislative





                                      I-5
<PAGE>   67
body, court, governmental authority or regulatory body, irrespective of the
manner in which such amendment, clarification or change is made known, which
amendment, clarification, or change is effective or such pronouncement or
decision is announced, in each case, on or after, the first date of issuance of
the Securities, there is more than an insubstantial risk that (i) the Trust is
or will be within 90 days of the date thereof, subject to United States federal
income tax with respect to interest accrued or received on the Debentures, (ii)
the Trust is, or will be within 90 days of the date thereof, subject to more
than a de minimis amount of taxes, duties or other governmental charges, or
(iii) interest payable by the Debenture Issuer to the Trust on the Debentures
is not, or within 90 days of the date thereof will not be, deductible, in whole
or in part, by the Debenture Issuer for United States federal income tax
purposes.

                 On and from the date fixed by the Regular Trustees for any
distribution of Debentures and dissolution of the Trust:  (i) the Securities
will no longer be deemed to be outstanding, (ii) The Depository Trust Company
(the "Depository") or its nominee (or any successor Clearing Agency or its
nominee), as the record Holder of the Preferred Securities, will receive a
registered global certificate or certificates representing the Debentures to be
delivered upon such distribution and any certificates representing Securities,
except for certificates representing Preferred Securities held by the
Depository or its nominee (or any successor Clearing Agency or its nominee),
will be deemed to represent beneficial interests in the Debentures having an
aggregate principal amount equal to the aggregate stated liquidation amount of,
with an interest rate identical to the Coupon Rate of, and accrued and unpaid
interest equal to accrued and unpaid Distributions on such Securities until
such certificates are presented to the Debenture Issuer or its agent for
transfer or reissue.

                 (d)      The Trust may not redeem fewer than all the
outstanding Securities unless all accrued and unpaid Distributions have been
paid on all Securities for all quarterly Distribution periods terminating on or
before the date of redemption.

                 (e)      If the Debentures are distributed to holders of the
Securities, pursuant to the terms of the Indenture, the Debenture Issuer will
use its best efforts to have the Debentures listed on the New York Stock
Exchange or on such other exchange as the Preferred Securities were listed
immediately prior to the distribution of the Debentures.

                 (f)      "Redemption or Distribution Procedures."

                 (i)      Notice of any redemption of, or notice of
         distribution of Debentures in exchange for the Securities (a
         "Redemption/Distribution Notice") will be given by the Trust by





                                      I-6
<PAGE>   68
         mail to each Holder of Securities to be redeemed or exchanged not
         fewer than 30 nor more than 60 days before the date fixed for
         redemption or exchange thereof which, in the case of a redemption,
         will be the date fixed for redemption of the Debentures.  For purposes
         of the calculation of the date of redemption or exchange and the dates
         on which notices are given pursuant to this Section 4(f)(i), a
         Redemption/ Distribution Notice shall be deemed to be given on the day
         such notice is first mailed by first-class mail, postage prepaid, to
         Holders of Securities.  Each Redemption/Distribution Notice shall be
         addressed to the Holders of Securities at the address of each such
         Holder appearing in the books and records of the Trust.  No defect in
         the Redemption/Distribution Notice or in the mailing of either thereof
         with respect to any Holder shall affect the validity of the redemption
         or exchange proceedings with respect to any other Holder.

                 (ii)     In the event that fewer than all the outstanding
         Securities are to be redeemed, the Securities to be redeemed shall be
         redeemed Pro Rata from each Holder of Preferred Securities, it being
         understood that, in respect of Preferred Securities registered in the
         name of and held of record by the Depository or its nominee (or any
         successor Clearing Agency or its nominee) or any nominee, the
         distribution of the proceeds of such redemption will be made to each
         Clearing Agency Participant (or Person on whose behalf such nominee
         holds such securities) in accordance with the procedures applied by
         such agency or nominee.

                 (iii)    If Securities are to be redeemed and the Trust gives
         a Redemption/Distribution Notice, which notice may only be issued if
         the Debentures are redeemed as set out in this Section 4 (which notice
         will be irrevocable), then (A) while the Preferred Securities are in
         book-entry only form, with respect to the Preferred Securities, by
         12:00 noon, New York City time, on the redemption date, provided that
         the Debenture Issuer has paid the Institutional Trustee a sufficient
         amount of cash in connection with the related redemption or maturity
         of the Debentures, the Institutional Trustee will deposit irrevocably
         with the Depository or its nominee (or successor Clearing Agency or
         its nominee) funds sufficient to pay the applicable Redemption Price
         with respect to the Preferred Securities and will give the Depository
         irrevocable instructions and authority to pay the Redemption Price to
         the Holders of the Preferred Securities, and (B) with respect to
         Preferred Securities issued in definitive form and Common Securities,
         provided that the Debenture Issuer has paid the Institutional Trustee
         a sufficient amount of cash in connection with the related redemption
         or maturity of the Debentures, the Institutional Trustee will pay the
         relevant Redemption Price to the Holders of





                                      I-7
<PAGE>   69
         such Securities by check mailed to the address of the relevant Holder
         appearing on the books and records of the Trust on the redemption
         date.  If a Redemption/Distribution Notice shall have been given and
         funds deposited as required, if applicable, then immediately prior to
         the close of business on the date of such deposit, or on the
         redemption date, as applicable, distributions will cease to accrue on
         the Securities so called for redemption and all rights of Holders of
         such Securities so called for redemption will cease, except the right
         of the Holders of such Securities to receive the Redemption Price, but
         without interest on such Redemption Price.  Neither the Regular
         Trustees nor the Trust shall be required to register or cause to be
         registered the transfer of any Securities that have been so called for
         redemption.  If any date fixed for redemption of Securities 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 fixed for redemption.  If payment of the Redemption Price in
         respect of any Securities is improperly withheld or refused and not
         paid either by the Institutional Trustee or by the Sponsor as
         guarantor pursuant to the relevant Securities Guarantee, Distributions
         on such Securities will continue to accrue from the original
         redemption date to the actual date of payment, in which case the
         actual payment date will be considered the date fixed for redemption
         for purposes of calculating the Redemption Price.

                 (iv)     Redemption/Distribution Notices shall be sent by the
         Regular Trustees on behalf of the Trust to (A) in respect of the
         Preferred Securities, the Depository or its nominee (or any successor
         Clearing Agency or its nominee) if the Global Certificates have been
         issued or, if Definitive Preferred Security Certificates have been
         issued, to the Holder thereof, and (B) in respect of the Common
         Securities to the Holder thereof.

                 (v)      Subject to the foregoing and applicable law
         (including, without limitation, United States federal securities
         laws), provided the acquiror is not the Holder of the Common
         Securities or the obligor under the Indenture, the Sponsor or any of
         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.

                 5.       Voting Rights - Preferred Securities.

                 (a)      Except as provided under Sections 5(b) and 7 and as
otherwise required by law and the Declaration, the Holders of the Preferred
Securities will have no voting rights.

                 (b)      Subject to the requirements set forth in this
paragraph, the Holders of a majority in aggregate liquidation amount of the
Preferred Securities, voting separately as a class may direct the time, method,
and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including the right to direct the
Institutional Trustee, as holder of the Debentures, to (i) exercise the
remedies available under the Indenture conducting any proceeding for any remedy
available to the Debenture Trustee, or exercising any trust or power conferred
on the Debenture Trustee with respect to the Debentures, (ii) waive any past
default and its consequences that is waivable under Section ___ of the
Indenture, or (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable, provided,
however, that, where a consent under the Indenture would require the consent or
act of the Holders of greater than a majority of the Holders in principal
amount of Debentures affected thereby, (a "Super Majority"), the Institutional
Trustee may only give such consent or take such action at the written direction
of the Holders of at least the proportion in liquidation amount of the
Preferred Securities which the relevant Super Majority represents of the
aggregate principal amount of the Debentures outstanding.  The Institutional
Trustee shall not revoke any action previously authorized or approved by a vote
of the Holders of the Preferred Securities.  Other than with respect to
directing the time, method and place of conducting any remedy available to the
Institutional Trustee or the Debenture Trustee as set forth above, the
Institutional Trustee shall not take any action in accordance with the
directions of the Holders of the Preferred Securities under this paragraph
unless the Institutional Trustee has obtained an opinion of tax counsel to the
effect that for the purposes of United States federal income tax the Trust will
not be classified as other than a grantor trust on account of such action.  If
a Declaration Event of Default has occurred and is continuing and such event is
attributable to the failure of the Debenture Issuer to pay interest or
principal on the Debentures on the date such interest or principal is otherwise
payable (or in the case of redemption, on the redemption date), then a holder
of Preferred Securities may directly institute a proceeding for enforcement of
payment to such Holder of the principal of or interest on the Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder (a "Direct Action") on or after the respective due
date specified in the Debentures.  In connection with such Direct Action, the
rights of





                                      I-9
<PAGE>   71
the holders of the Common Securities Holder will be subrogated to the rights of
such holder of Preferred Securities to the extent of any payment made by the
Issuer to such holder of Preferred Securities in such Direct Action.  Except as
provided in the preceding sentences, the Holders of Preferred Securities will
not be able to exercise directly any other remedy available to the holders of
the Debentures.

                 Any approval or direction of Holders of Preferred Securities
may be given at a separate meeting of Holders of Preferred Securities convened
for such purpose, at a meeting of all of the Holders of Securities in the Trust
or pursuant to written consent.  The Regular Trustees will cause a notice of
any meeting at which Holders of Preferred Securities are entitled to vote, or
of any matter upon which action by written consent of such Holders is to be
taken, to be mailed to each Holder of record of Preferred Securities.  Each
such notice will include a statement setting forth (i) the date of such meeting
or the date by which such action is to be taken, (ii) a description of any
resolution proposed for adoption at such meeting on which such Holders are
entitled to vote or of such matter upon which written consent is sought and
(iii) instructions for the delivery of proxies or consents.

                 No vote or consent of the Holders of the Preferred Securities
will be required for the Trust to redeem and cancel Preferred Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                 Notwithstanding that Holders of Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Preferred Securities that are owned by the Sponsor or any Affiliate of
the Sponsor shall not be entitled to vote or consent and shall, for purposes of
such vote or consent, be treated as if they were not outstanding.

                 6.       Voting Rights - Common Securities.

                 (a)      Except as provided under Sections 7(b), (c) and 8 as
otherwise required by law and the Declaration, the Holders of the Common
Securities will have no voting rights.

                 (b)      The Holders of the Common Securities are entitled, in
accordance with Article V of the Declaration, to vote to appoint, remove or
replace any Trustee or to increase or decrease the number of Trustees.

                 (c)      Subject to Section 2.6 of the Declaration and only
after the Event of Default with respect to the Preferred Securities has been
cured, waived, or otherwise eliminated and subject to the requirements of the
second to last sentence of this paragraph, the Holders of a Majority in
liquidation amount of the





                                      I-10
<PAGE>   72
Common Securities, voting separately as a class, may direct the time, method,
and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including (i) directing the time,
method, place of conducting any proceeding for any remedy available to the
Debenture Trustee, or exercising any trust or power conferred on the Debenture
Trustee with respect to the Debentures, (ii) waive any past default and its
consequences that is waivable under Section ____ of the Indenture, or (iii)
exercise any right to rescind or annul a declaration that the principal of all
the Debentures shall be due and payable, provided that, where a consent or
action under the Indenture would require the consent or act of the Holders of
greater than a majority in principal amount of Debentures affected thereby (a
"Super Majority"), the Institu- tional Trustee may only give such consent or
take such action at the written direction of the Holders of at least the
proportion in liquidation amount of the Common Securities which the relevant
Super Majority represents of the aggregate principal amount of the Debentures
outstanding.  Pursuant to this Section 6(c), the Institutional Trustee shall
not revoke any action previously authorized or approved by a vote of the
Holders of the Preferred Securities.  Other than with respect to directing the
time, method and place of conducting any remedy available to the Institutional
Trustee or the Debenture Trustee as set forth above, the Institutional Trustee
shall not take any action in accordance with the directions of the Holders of
the Common Securities under this paragraph unless the Institutional Trustee has
obtained an opinion of tax counsel to the effect that for the purposes of
United States federal income tax the Trust will not be classified as other than
a grantor trust on account of such action.  If the Institutional Trustee fails
to enforce its rights under the Declaration, any Holder of Common Securities
may institute a legal proceeding directly against any Person to enforce the
Institutional Trustee's rights under the Declaration, without first instituting
a legal proceeding against the Institutional Trustee or any other Person.

                 Any approval or direction of Holders of Common Securities may
be given at a separate meeting of Holders of Common Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent.  The Regular Trustees will cause a notice of any
meeting at which Holders of Common Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Common Securities.  Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such Holders are entitled to vote or of
such matter upon which written consent is





                                      I-11
<PAGE>   73
sought and (iii) instructions for the delivery of proxies or consents.

                 No vote or consent of the Holders of the Common Securities
will be required for the Trust to redeem and cancel Common Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                 7.       Amendments to Declaration and Indenture.

                 (a)      In addition to any requirements under Section 12.1 of
the Declaration, if any proposed amendment to the Declaration provides for, or
the Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 of the Declaration, then the Holders of outstanding Securities
voting together as a single class, will be entitled to vote on such amendment
or proposal (but not on any other 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 Securities, affected thereby,
provided, however, if any amendment or proposal referred to in clause (i) above
would adversely affect only the Preferred Securities or only the Common
Securities, then only the affected 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 a Majority in liquidation amount of such class of
Securities.

                 (b)      In the event the consent of the Institutional Trustee
as the holder of the Debentures is required under the Indenture with respect to
any amendment, modification or termination on the Indenture or the Debentures,
the Institutional Trustee shall request the written direction of the Holders of
the Securities with respect to such amendment, modification or termination and
shall vote with respect to such amendment, modification or termination as
directed by a Majority in liquidation amount of the Securities voting together
as a single class; provided, however, that where a consent under the Indenture
would require the consent of the holders of greater than a majority in
aggregate principal amount of the Debentures (a "Super Majority"), the
Institutional Trustee may only give such consent at the direction of the
Holders of at least the proportion in liquidation amount of the Securities
which the relevant Super Majority represents of the aggregate principal amount
of the Debentures outstanding; provided, further, that the Institutional
Trustee shall not take any action in accordance with the directions of the
Holders of the Securities under this Section 7(b) unless the Institutional
Trustee has obtained an opinion of tax counsel to the effect that for the
purposes of United States federal income





                                      I-12
<PAGE>   74
tax the Trust will not be classified as other than a grantor trust on account
of such action.

                 8.       Pro Rata.

                 A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each
Holder of Securities according to the aggregate liquidation amount of the
Securities held by the relevant Holder in relation to the aggregate liquidation
amount of all Securities outstanding unless, in relation to a payment, an Event
of Default under the Declaration has occurred and is continuing, in which case
any funds available to make such payment shall be paid first to each Holder of
the Preferred Securities pro rata according to the aggregate liquidation amount
of Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Preferred Securities, to
each Holder of Common Securities pro rata according to the aggregate
liquidation amount of Common Securities held by the relevant Holder relative to
the aggregate liquidation amount of all Common Securities outstanding.

                 9.       Ranking.

                 The Preferred Securities rank pari passu and payment thereon
shall be made Pro Rata with the Common Securities except that, where a
Declaration Event of Default occurs and is continuing the rights of Holders of
the Common Securities to payment in respect of Distributions and payments upon
liquidation, redemption and otherwise are subordinated to the rights to payment
of the Holders of the Preferred Securities.

                 10.      Listing.

                 The Regular Trustees shall use their best efforts to cause the
Preferred Securities to be listed for quotation on the New York Stock Exchange,
Inc.

                 11.      Acceptance of Securities Guarantee and Indenture.

                 Each Holder of Preferred Securities and Common Securities, by
the acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.

                 12.      No Preemptive Rights.

to subscribe for any additional securities.

                         [FORM OF REVERSE OF SECURITY]

                 Distributions payable on each  Preferred Security will be
fixed at a rate per annum of ______% (the "Coupon Rate") of the stated
liquidation amount of $__ per Preferred Security, such rate being the rate of
interest payable on the Debentures to be held by the Institutional Trustee.
Distributions in arrears for more than one quarter will bear interest thereon
compounded quarterly at the Coupon Rate (to the extent permitted by applicable
law).  The term "Distributions" as used herein includes such cash distributions
and any such interest payable unless otherwise stated.  A Distribution is
payable only to the extent that payments are made in respect of the Debentures
held by the Institutional Trustee and to the extent the Institutional Trustee
has funds available therefor.  The amount of Distributions payable for any
period will be computed for any full quarterly Distribution period on the basis
of a 360- day year of twelve 30-day months, and for any period shorter than a
full quarterly Distribution period for which Distributions are computed,
Distributions will be computed on the basis of the actual number of days
elapsed per 90-day quarter.

                 Except as otherwise described below, distributions on the
Preferred Securities will be cumulative, will accrue from the date of original
issuance and will be payable quarterly in arrears, on [March 31, June 30,
September 30 and December 31] of each year, commencing on [June 30,] 1996, to
[Holders of record fifteen (15) days prior to such payment dates, which payment
dates shall correspond to the interest payment dates on the Debentures.]  The
Debenture Issuer has the right under the Indenture to defer payments of
interest by extending the interest payment period from time to time on the
Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period"), provided that no Extension Period shall last beyond the
date of the maturity of the Debentures and as a consequence of such deferral,
Distributions will also be deferred.  Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period. Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity of
the Debentures.  Payments of accrued Distributions will be payable to Holders
as they appear on the books and records of the Trust on the first record date
after the end of the Extension Period.  Upon the termination of any Extension
Period and the payment of all amounts then due, the Debenture Issuer may
commence a new Extension Period, subject to the above requirements.

                         [FORM OF REVERSE OF SECURITY]

                 Distributions payable on each Common Security will be fixed at
a rate per annum of ______% (the "Coupon Rate") of the stated liquidation
amount of $__ per Common Security, such rate being the rate of interest payable
on the Debentures to be held by the Institutional Trustee.  Distributions in
arrears for more than one quarter will bear interest thereon compounded
quarterly at the Coupon Rate (to the extent permitted by applicable law).  The
term "Distributions" as used herein includes such cash distributions and any
such interest payable unless otherwise stated.  A Distribution is payable only
to the extent that payments are made in respect of the Debentures held by the
Institutional Trustee and to the extent the Institutional Trustee has funds
available therefor.  The amount of Distributions payable for any period will be
computed for any full quarterly Distribution period on the basis of a 360- day
year of twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 90-day quarter.

                 Except as otherwise described below, distributions on the
Common Securities will be cumulative, will accrue from the date of original
issuance and will be payable quarterly in arrears, on [March 31, June 30,
September 30 and December 31] of each year, commencing on [June 30,] 1996, to
Holders of record fifteen (15) days prior to such payment dates, which payment
dates shall correspond to the interest payment dates on the Debentures.  The
Debenture Issuer has the right under the Indenture to defer payments of
interest by extending the interest payment period from time to time on the
Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period"), provided that no Extension Period shall last beyond the
date of the maturity of the Debentures and as a consequence of such deferral,
Distributions will also be deferred.  Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period. Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity
date of the Debentures.  Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the first
record date after the end of the Extension Period.  Upon the termination of any
Extension Period and the payment of all amounts then due, the Debenture Issuer
may commence a new Extension Period, subject to the above requirements.

Event of Default under the Indenture:

                  (i)        is not waivable under the Indenture, the Event
         of Default under the Declaration shall also not be waivable;
         or

                  (ii)       requires the consent or vote of greater than a

subsequent or other default or an Event of Default with respect to the Preferred
Securities or impair any right consequent thereon. Any waiver by the Holders of
the Preferred Securities of an Event of Default with respect to the Preferred
Securities shall also be deemed to constitute a waiver by the Holders of the

Securities for all purposes of this Declaration without any further act, vote,
or consent of the Holders of the Common Securities.

                  (b)        The Holders of a Majority in liquidation amount

                  (ii)        requires the consent or vote of a Super Majority
         to be waived, except where the Holders of the Common Securities are 
         deemed to have waived such Event of Default under the Declaration as 
         provided below in this Section 2.6(b), the Event of Default under the
         Declaration may only be waived by the vote of the Holders of at least
         the proportion in liquidation amount of the Common Securities that the
         relevant Super Majority represents of the aggregate principal amount of
         the Debentures outstanding;

provided further, each Holder of Common Securities will be deemed to have waived
any such Event of Default and all Events of Default with respect to the Common
Securities and its consequences until all Events of Default with respect to the
Preferred Securities have been cured, waived or otherwise eliminated, and until
such Events of Default have been so cured, waived or otherwise eliminated, the
Institutional Trustee will be deemed to be acting solely on behalf of the
Holders of the Preferred Securities and only the Holders of the Preferred
Securities will have the right to direct the Institutional Trustee in accordance
with the terms of the Securities. The foregoing provisions of this Section
2.6(b) shall be in lieu of ss.ss. 316(a)(1)(A) and 316(a)(1)(B) of the Trust
Indenture Act and such ss.ss. 316(a)(1)(A) and 316(a)(1)(B) of the Trust
Indenture Act are hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act. Subject to the foregoing
provisions of this Section 2.6(b), upon such waiver, any such default shall
cease to exist and any Event of Default with respect to the Common Securities
arising therefrom shall be deemed to have been cured for every purpose of this
Declaration, but no such waiver shall extend to any subsequent or other default
or Event of Default with respect to the Common Securities or impair any right
consequent thereon.

                  (c)         A waiver of an Event of Default under the 
Indenture by the Institutional Trustee at the direction of the Holders of the 
Preferred Securities, constitutes a waiver of the corresponding Event of 
Default under this Declaration. The foregoing provisions of this Section 
2.6(c) shall be in lieu of ss. 316(a)(1)(B) of the Trust Indenture Act and 
such ss. 316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded 
from this Declaration and the Securities, as permitted by the Trust Indenture 
Act.

determines that the withholding of such notice is in the interests of the
Holders of the Securities.

                  (b)        The Institutional Trustee shall not be deemed to
have knowledge of any default except:

                  (i)        a default under Sections ____ and ____ of the

                  purposes,

         holding the Debentures, but shall distribute all such proceeds to 
         Holders of Securities pursuant to the terms of this Declaration and 
         of the Securities;

                  (i)        establish and maintain a segregated non-interest

                                       17

<PAGE>   23

         in the name of and under the exclusive control of the Institutional
         Trustee on behalf of the Holders of the Securities and, upon the
         receipt of payments of funds made in respect of the Debentures held by
         the Institutional Trustee, deposit such funds into the Institutional
         Trustee Account and make payments to the Holders of the Preferred
         Securities and Holders of the Common Securities from the Institutional
         Trustee Account in accordance with Section 6.1. Funds in the
         Institutional Trustee Account shall be held uninvested until disbursed
         in accordance with this Declaration. The Institutional Trustee Account
         shall be an account that is maintained with a banking institution the
         rating on whose long-term unsecured indebtedness is at least equal to
         the rating assigned to the Preferred Securities by a "nationally
         recognized statistical rating organization", as that term is defined
         for purposes of Rule 436(g)(2) under the Securities Act;

                  (ii)       engage in such ministerial activities as shall be
         necessary or appropriate to effect the redemption of the Preferred
         Securities and the Common Securities to the extent the Debentures are

                  (iii)      upon written notice of distribution issued by the
         Regular Trustees in accordance with the terms of the Securities, engage
         in such ministerial activities as shall be necessary or appropriate to
         effect the distribution of the Debentures to Holders of Securities upon
         the occurrence of certain special events (as may be defined in the
         terms of the Securities) arising from a change in law or a change in
         legal interpretation or other specified circumstances pursuant to the
         terms of the Securities.

                  (d)        The Institutional Trustee shall take all actions 
and perform such duties as may be specifically required of the Institutional
Trustee pursuant to the terms of the Securities.

                  (e)        The Institutional Trustee shall take any Legal 
Action which arises out of or in connection with an Event of Default of which a
Responsible Officer of the Institutional Trustee has actual knowledge or the
Institutional Trustee's duties and obligations under this Declaration or the
Trust Indenture Act; provided however, that if a Declaration Event of Default
has occurred and is continuing and such event is attributable to the failure of
the Debenture Issuer to pay interest or principal on the Debentures on the date
such interest or principal is otherwise payable (or in the case of redemption,
on the redemption date), then a Holder of Preferred Securities may directly
institute a proceeding for enforcement of payment to such Holder of the
principal of or interest on the Debentures having a principal amount equal to
the aggregate liquidation amount of the Preferred Securities of such Holder (a
"Direct






                                       18

Action") on or after the respective due date specified in the Debentures. In
connection with such Direct Action, the rights of the Holders of the Common
Securities Holder will be subrogated to the rights of such Holder of Preferred
Securities to the extent of any payment made by the Issuer to such Holder of
Preferred Securities in such Direct Action. Except as provided in the preceding
sentences, the Holders of Preferred Securities will not be able to exercise
directly any other remedy available to the holders of the Debentures.

                  (f)        The Institutional Trustee shall not resign as a
Trustee unless either:

                  (i)        the Trust has been completely liquidated and the
         proceeds of the liquidation distributed to the Holders of
         Securities pursuant to the terms of the Securities; or

                  (ii)       a Successor Institutional Trustee has been
         appointed and has accepted that appointment in accordance
         with Section 5.7.

                  (g)        The Institutional Trustee shall have the legal 
power to exercise all of the rights, powers and privileges of a holder of
Debentures under the Indenture and, if an Event of Default actually known to a
Responsible Officer of the Institutional Trustee occurs and is continuing, the
Institutional Trustee shall, for the benefit of Holders of the Securities,
enforce its rights as holder of the Debentures subject to the rights of the
Holders pursuant to the terms of such Securities.

                  (h)        The Institutional Trustee may authorize one or more
Persons (each, a "Paying Agent") to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all securities and
any such Paying Agent shall comply with ss. 317(b) of the Trust Indenture Act.
Any Paying Agent may be removed by the Institutional Trustee at any time and a
successor Paying Agent or additional Paying Agents may be appointed at any time
by the Institutional Trustee.

                  (i)        Subject to this Section 3.8, the Institutional 
Trustee shall have none of the duties, liabilities, powers or the authority of
the Regular Trustees set forth in Section 3.6.

                  The Institutional Trustee must exercise the powers set forth
in this Section 3.8 in a manner that is consistent with the purposes and
functions of the Trust set out in Section 3.3, and the Institutional Trustee
shall not take any action that is inconsistent with the purposes and functions
of the Trust set out in Section 3.3.

                  (a)       The Institutional 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 Declaration and no implied covenants shall be read into this
Declaration against the Institutional Trustee. In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6) of which a
Responsible Officer of the Institutional Trustee has actual knowledge, the
Institutional Trustee shall exercise such of the rights and powers vested in it
by this Declaration, 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 or her own affairs.

                  (b)       No provision of this Declaration shall be construed
to relieve the Institutional 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 an Event of Default
         and after the curing or waiving of all such Events of De-
         fault that may have occurred:

                        (A) the duties and obligations of the Institutional
                  Trustee shall be determined solely by the express provisions
                  of this Declaration and the Institutional Trustee shall not be
                  liable except for the performance of such duties and
                  obligations as are specifically set forth in this Declaration,
                  and no implied covenants or obligations shall be read into
                  this Declaration against the Institutional Trustee; and

                        (B) in the absence of bad faith on the part of the
                  Institutional Trustee, the Institutional 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 Institutional
                  Trustee and conforming to the requirements of this
                  Declaration; but in the case of any such certificates or
                  opinions that by any provision hereof are specifically
                  required to be furnished to the Institutional Trustee, the
                  Institutional Trustee shall be under a duty to examine the
                  same to determine whether or not they conform to the
                  requirements of this Declaration;

                  (ii)      the Institutional Trustee shall not be liable
         for any error of judgment made in good faith by a Responsi-
         ble Officer of the Institutional Trustee, unless it shall be





                                       20

         proved that the Institutional Trustee was negligent in
         ascertaining the pertinent facts;

                  (iii)        the Institutional 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 Securities relating to 
         the time, method and place of conducting any proceeding for any remedy
         available to the Institutional Trustee, or exercising any trust or 
         power conferred upon the Institutional Trustee under this Declaration;

                  (iv)         no provision of this Declaration shall require
         the Institutional Trustee to expend or risk its own funds or otherwise
         incur personal financial liability in the performance of any of its
         duties or in the exercise of any of its rights or powers, if it shall
         have reasonable grounds for believing that the repayment of such funds
         or liability is not reasonably assured to it under the terms of this
         Declaration or indemnity reasonably satisfactory to the Institutional
         Trustee against such risk or liability is not reasonably assured to
         it;

                  (v)          the Institutional Trustee's sole duty with 
         respect to the custody, safe keeping and physical preservation of the
         Debentures and the Institutional Trustee Account shall be to deal with
         such property in a similar manner as the Institutional Trustee deals
         with similar property for its own account, subject to the protections
         and limitations on liability afforded to the Institutional Trustee
         under this Declaration and the Trust Indenture Act;

                  (vi)         the Institutional Trustee shall have no duty or
         liability for or with respect to the value, genuineness, existence or
         sufficiency of the Debentures or the payment of any taxes or
         assessments levied thereon or in connection therewith;

                  (vii)        the Institutional Trustee shall not be liable 
         for any interest on any money received by it except as it may
         otherwise agree with the Sponsor. Money held by the Institutional
         Trustee need not be segregated from other funds held by it except in
         relation to the Institutional Trustee Account maintained by the
         Institutional Trustee pursuant to Section 3.8(c)(i) and except to the
         extent otherwise required by law; and

                  (viii)       the Institutional Trustee shall not be 
         responsible for monitoring the compliance by the Regular Trustees or
         the Sponsor with their respective duties under this Declaration, nor

         matter be  proved or established before taking, suffering or omitting
         any action hereunder, the Institutional Trustee (unless other evidence
         is herein specifically prescribed) may, in the absence of bad faith on

         unless such Holder shall have provided to the Institutional Trustee
         security and indemnity, reasonably satisfactory to the Institutional
         Trustee, against the costs, expenses (including attorneys' fees and
         expenses and the expenses of the Institutional Trustee's agents,
         nominees or custodians) 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 Institutional Trustee provided,
         that, nothing contained in this Section 3.10(a)(vi) shall be taken to
         relieve the Institutional Trustee, upon the occurrence of an Event of

         it by this Declaration;

                  (vii)         the Institutional Trustee shall not be bound

                  (viii)        the Institutional Trustee may execute any of

                  (ix)          any action taken by the Institutional Trustee 
         or its agents hereunder shall bind the Trust and the Holders of the
         Securities, and the signature of the Institutional Trustee or its

         action and no third party shall be required to inquire as to the
         authority of the Institutional Trustee to so act or as to its
         compliance with any of the terms and provisions of this Declaration,
         both of which shall be conclusively evidenced by the Institutional
         Trustee's or its agent's taking such action;

                  (x)           whenever in the administration of this

         instructions may only be given by the Holders of the same proportion

         the Institutional Trustee under the terms of the Securities in respect
         of such





                                       23

         remedy, right or action, (ii) may refrain from enforcing such remedy or
         right or taking such other action until such instructions are received,

         provisions of this Declaration.

                  (b)         No provision of this Declaration shall be deemed
to impose any duty or obligation on the Institutional 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 Institutional 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 Institutional Trustee shall be construed to be a duty.

SECTION 3.11      Delaware Trustee.

                  Notwithstanding any other provision of this Declaration other

Trustees.

SECTION 3.13      Not Responsible for Recitals or Issuance of Securities.

                  The recitals contained in this Declaration and the Securities
shall be taken as the statements of the Sponsor, and the Trustees do not assume
any responsibility for their correctness. The Trustees make no representations
as to the value or






                                       24

condition of the property of the Trust or any part thereof. The Trustees make no
representations as to the validity or sufficiency of this Declaration or the
Securities.

SECTION 3.14      Duration of Trust.

                  The Trust, unless terminated pursuant to the provisions of

and assets substantially as an entirety to any corporation or other body,
except as described in Section 3.15(b) and (c).

                  (b)         The Trust may, with the consent of the Regular 
Trustees or, if there are more than two, a majority of the Regular Trustees and
without the consent of the Holders of the Securities, the Delaware Trustee or
the Institutional Trustee, consolidate, amalgamate, merge with or into, or be
replaced by a trust organized as such under the laws of any State; provided
that:

                  (i)        such successor entity (the "Successor Entity")
         either:

                             (A)      expressly assumes all of the obligations 
                  of the Trust under the Securities; or

                             (B)      substitutes for the 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 with respect to Distributions and payments 
                  upon liquidation, redemption and otherwise;

                  (ii)       the Debenture Issuer expressly acknowledges a 
         trustee of the Successor Entity that possesses the same powers and 
         duties as the Institutional Trustee as the Holder of the Debentures;

                  (iii)      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;





                                       25

<PAGE>   31



                  (iv)       such merger, consolidation, amalgamation or 
         replacement does not cause the Preferred Securities (including any
         Successor Securities) to be downgraded by any nationally recognized
         statistical rating organization;

                  (v)        such merger, consolidation, amalgamation or 
         replacement does not adversely affect the rights, preferences and
         privileges of the Holders of the Securities (including any Successor
         Securities) in any material respect (other than with respect to any
         dilution of such Holders' interests in the Preferred Securities as a
         result of such merger, consolidation, amalgamation or replacement);

                  (vi)       such Successor Entity has a purpose identical to
         that of the Trust;

                  (vii)      prior to such merger, consolidation, amalgamation
         or replacement, the Sponsor has received an opinion of a nationally
         recognized independent counsel to the Trust experienced in such
         matters to the effect that:

                             (A)     such merger, consolidation, amalgamation or
                  replacement does not adversely affect the rights, preferences
                  and privileges of the Holders of the Securities (including any
                  Successor Securities) in any material respect (other than with
                  respect to any dilution of the Holders' interest in the new
                  entity); and

                             (B)     following such merger, consolidation,
                  amalgamation or replacement, neither the Trust nor the
                  Successor Entity will be required to register as an Investment
                  Company;

                             (C)     following such merger, consolidation,
                  amalgamation or replacement, the Trust (or the Successor
                  Entity) will continue to be classified as a grantor trust for
                  United States federal income tax purposes; and

                  (viii)     the Sponsor guarantees the obligations of such
         Successor Entity under the Successor Securities at least to the extent
         provided by the Preferred Securities Guarantees.

                  (c)        Notwithstanding Section 3.15(b), the Trust shall 
not, except with the consent of Holders of 100% in liquidation amount of the
Securities, consolidate, amalgamate, merge with or into, or be replaced by any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger or
replacement would cause the Trust or Successor Entity to be classified as other
than a grantor trust for United States federal income tax purposes.

shall act as Institutional Trustee which shall:

                  (i)        not be an Affiliate of the Sponsor; and

         of Columbia authority. If such corporation publishes reports of
         condition at least annually, pursuant to law or to the requirements of
         the supervising or examining authority referred to above, then for the
         purposes of this Section 5.3(a)(ii), the combined capital and surplus

Securities (as if it were the obligor referred to in ss. 310(b) of the Trust
Indenture Act) shall in all respects comply with the provisions of ss. 310(b)
of the Trust Indenture Act.

                  (d)        The Preferred Securities Guarantee shall be deemed

Such court may thereupon, after prescribing such notice, if any, as it may deem
proper and prescribe, appoint a Successor Institutional Trustee or Successor
Delaware Trustee, as the case may be.

                  (f) No Institutional Trustee or Delaware Trustee shall be

SECTION 5.8       Vacancies among Trustees.

                  If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 5.1, or if the number of
Trustees is increased pursuant to Section 5.1, a vacancy shall occur. A
resolution certifying the existence of such vacancy by the Regular Trustees or,
if there are more than two, a majority of the Regular Trustees shall be
conclusive evidence of the existence of such vacancy. The vacancy shall be
filled with a Trustee appointed in accordance with Section 5.7.

                  The death, resignation, retirement, removal, bankruptcy,
dissolution, liquidation, incompetence or incapacity to perform the duties of a
Trustee shall not operate to annul the Trust. Whenever a vacancy in the number
of Regular Trustees shall occur, until such vacancy is filled by the appointment
of a Regular Trustee in accordance with Section 5.7, the Regular Trustees in
office, regardless of their number, shall have all the powers granted to the
Regular Trustees and shall discharge all the duties imposed upon the Regular
Trustees by this Declaration.

thereof shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours before
a meeting. Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting. The presence (whether in person or by
telephone) of a Regular Trustee at a meeting shall constitute a waiver of notice
of such meeting except where a Regular Trustee attends a meeting for the express
purpose of objecting to the transaction of any activity on the ground that the
meeting has not been lawfully called or convened. Unless provided otherwise in
this Declaration, any action of the Regular Trustees may be taken at a meeting
by vote of a majority of the Regular Trustees present (whether in person or by
telephone) and eligible to vote with respect to such matter, provided that a
Quorum is present, or without a meeting by the unanimous written consent of the
Regular Trustees. In the event there is only one Regular Trustee, any and all
action of such Regular Trustee shall be evidenced by a written consent of such
Regular Trustee.

SECTION 5.11      Delegation of Power.

                  (a) Any Regular 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
3.6, including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing; and

                  (b) the Regular Trustees shall have power to delegate from
time to time to such of their number or to officers of the Trust the doing of
such things and the execution of such instruments either in the name of the
Trust or the names of the Regular Trustees or otherwise as the Regular Trustees
may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

Section 5.12      Merger, Conversion, Consolidation or Succession to Business.

         Any corporation into which the Institutional Trustee or the Delaware
Trustee, as the case may be, may be merged or converted or with which either may
be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Institutional Trustee or the Delaware Trustee, as the
case may be, shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Institutional Trustee or
the Delaware Trustee, as the case may be, shall be the successor of the
Institutional Trustee or the Delaware Trustee, as the case may be, hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article,




                                       33

                                  DISTRIBUTIONS

SECTION 6.1       Distributions.

                  Holders shall receive Distributions (as defined herein) in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Preferred Securities and the Common
Securities in accordance with the preferences set forth in their respective
terms. If and to the extent that the Debenture Issuer makes a payment of
interest (including Compounded Interest (as defined in the Indenture) and
Additional Interest (as defined in the Indenture)), premium and/or principal on
the Debentures held by the Institutional Trustee (the amount of any such payment
being a "Payment Amount"), the Institutional Trustee shall and is directed, to
the extent funds are available for that purpose, to make a distribution (a
"Distribution") of the Payment Amount to Holders.


                                   ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1       General Provisions Regarding Securities.

                  (a) The Regular Trustees shall on behalf of the Trust issue
one class of preferred securities representing undivided beneficial interests in
the assets of the Trust having such terms as are set forth in Annex I (the
"Preferred Securities") and one class of common securities representing
undivided beneficial interests in the assets of the Trust having such terms as
are set forth in Annex I (the "Common Securities.") The Trust shall issue no
securities or other interests in the assets of the Trust other than the
Preferred Securities and the Common Securities.

                  (b) The Certificates shall be signed on behalf of the Trust by
a Regular Trustee. Such signature shall be the manual signature of any present
or any future Regular Trustee. In case any Regular Trustee of the Trust who
shall have signed any of the Securities shall cease to be such Regular Trustee
before the Certificates so signed shall be delivered by the Trust, such
Certificates nevertheless may be delivered as though the person who signed such
Certificates had not ceased to be such Regular Trustee; and any Certificate may
be signed on behalf of the Trust by such persons who, at the actual date of
execution of such Security, shall be the Regular Trustees of the Trust, although
at the date of the execution and delivery of the Declara-





                                       34

tion any such person was not such a Regular Trustee. Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Regular Trustees, as evidenced by their execution
thereof, and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements as the Regular Trustees may deem
appropriate, or as may be required to comply with any law or with any rule or
regulation of any stock exchange on which Securities may be listed, or to
conform to usage.

                  (c)   The consideration received by the Trust for the issuance
of the Securities shall constitute a contribution to the capital of the Trust
and shall not constitute a loan to the Trust.

                  (d)   Upon issuance of the Securities as provided in
this Declaration, the Securities so issued shall be deemed to be
validly issued, fully paid and non-assessable.

                  (e)   Every Person, by virtue of having become a Holder or a
Preferred Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration.

SECTION 7.2       Paying Agent.

                  In the event that the Preferred Securities are not in
book-entry only form, the Trust shall maintain in the Borough of Manhattan, City
of New York, State of New York, an office or agency where the Preferred
Securities may be presented for payment ("Paying Agent). The Trust may appoint
the Paying Agent and may appoint one or more additional paying agents in such
other locations as it shall determine. The term "Paying Agent" includes any
additional paying agent. The Trust may change any Paying Agent without prior
notice to any Holder. The Trust shall notify the Institutional Trustee of the
name and address of any Agent not a party to this Declaration. If the Trust
fails to appoint or maintain another entity as Paying Agent, the Institutional
Trustee shall act as such. The Trust or any of its Affiliates may act as Paying
Agent. The Trust shall initially act as Paying Agent for the Preferred
Securities and the Common Securities.

require) in respect of any tax or other government charges that may be imposed
in relation to it. Upon surrender for registration of transfer of any
Certificate, the Regular Trustees shall cause one or more new Certificates to be
issued in the name of the designated transferee or transferees. Every
Certificate surrendered for registration of transfer shall be accompanied by a
written instrument of transfer in form satisfactory to the Regular Trustees duly

        force and effect;

                  (b)   the Trust and the Trustees shall be entitled to deal

        (including the payment of Distributions on the Global Certificates and
        receiving approvals, votes or consents hereunder) as the Holder of the
        Preferred Securities and the sole holder of the Global Certificates and
        shall have no obligation to the Preferred Security Beneficial Owners;

                  (c)   to the extent that the provisions of this Section 9.4
         conflict with any other provisions of this Declaration, the provisions
         of this Section 9.4 shall control; and

                  (d)   the rights of the Preferred Security Beneficial Owners
         shall be exercised only through the Clearing Agency and shall be
         limited to those established by law and agreements between such
         Preferred Security Beneficial Owners and the Clearing Agency and/or the
         Clearing Agency Participants and receive and transmit payments of
         Distributions on the Global Certificates to such Clearing Agency
         Participants. DTC will make book entry transfers among the Clearing

                  (b)        there shall be delivered to the Regular Trustees
         such security or indemnity as may be required by them to
         keep each of them harmless.

then, in the absence of notice that such Certificate shall have been acquired by
a bona fide purchaser, any Regular Trustee on behalf of the Trust shall execute
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Certificate, a new Certificate of like denomination. In connection
with the issuance of any new Certificate under this Section 9.8, the Regular
Trustees 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
Certificate issued pursuant to this Section shall constitute conclusive evidence
of an ownership interest in the relevant Securities, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

                  (i)   personally liable for the return of any portion of the
         capital contributions (or any return thereon) of the Holders of the
         Securities which shall be made solely from assets of the Trust; and

                  (ii)  be required to pay to the Trust or to any Holder
         of Securities any deficit upon dissolution of the Trust or
         otherwise.

                  (b)   The Holder of the Common Securities shall be liable for

                  (c)   Pursuant to ss. 3803(a) of the Business Trust Act, the

organized under the General Corporation Law of the State of Delaware.

                  (a)   No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust or any Covered Person for any
loss, damage or claim incurred by reason of 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 the
authority conferred on such Indemnified Person by this Declaration or by law,
except that an Indemnified Person shall be liable for any such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence or
willful misconduct with respect to such acts or omissions.

                  (b)  An Indemnified Person shall be fully protected in relying
in good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which Distributions to Holders of Securities might properly be paid.

SECTION 10.3      Fiduciary Duty.

                  (a)   To the extent that, at law or in equity, an Indemnified
Person has duties (including fiduciary duties) and liabilities relating thereto
to the Trust or to any other Covered Person, an Indemnified Person acting under
this Declaration shall not be liable to the Trust or to any other Covered Person
for its good faith reliance on the provisions of this Declaration. The
provisions of this Declaration, to the extent that they restrict the duties and
liabilities of an Indemnified Person otherwise existing at law or in equity
(other than the duties imposed on the Institutional Trustee under the Trust
Indenture Act), are agreed by the parties hereto to replace such other duties
and liabilities of such Indemnified Person.

                  (b)   Unless otherwise expressly provided herein:

                  (i)   whenever a conflict of interest exists or arises
         between any Covered Persons; or

                  (ii)  whenever this Declaration or any other agreement
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case





                                       41

<PAGE>   47



the relative interest of each party (including its own interest) to such
conflict, agreement, transaction or situation and the benefits and burdens
relating to such interests, any customary or accepted industry practices, and
any applicable generally accepted accounting practices or principles. In the
absence of bad faith by the Indemnified Person, the resolution, action or term
so made, taken or provided by the Indemnified Person shall not constitute a
breach of this Declaration or any other agreement contemplated herein or of any
duty or obligation of the Indemnified Person at law or in equity or otherwise.

                  (c)   Whenever in this Declaration an Indemnified
Person is permitted or required to make a decision:

                  (i)   in its "discretion" or under a grant of similar 
         authority, the Indemnified Person shall be entitled to consider such
         interests and factors as it desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

                  (ii)  in its "good faith" or under another express standard,
         the Indemnified Person shall act under such express standard and shall
         not be subject to any other or different standard imposed by this
         Declaration or by applicable law.

SECTION 10.4      Indemnification.

                  (a) (i) The Debenture Issuer shall indemnify, to the full
extent permitted by law, any Company Indemnified Person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the Trust) by reason of the fact
that he is or was a Company Indemnified Person against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Trust, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe his conduct was
unlawful. The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the Company Indemnified Person
did not act in good faith and in a manner which he reasonably believed to be in
or not opposed to the best interests of the Trust, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.






                                       42

<PAGE>   48



                  (ii) The Debenture Issuer shall indemnify, to the full extent
         permitted by law, any Company Indemnified Person who was or is a party
         or is threatened to be made a party to any threatened, pending or
         completed action or suit by or in the right of the Trust to procure a
         judgment in its favor by reason of the fact that he is or was a Company
         Indemnified Person against expenses (including attorneys' fees)
         actually and reasonably incurred by him in connection with the defense
         or settlement of such action or suit if he acted in good faith and in a
         manner he reasonably believed to be in or not opposed to the best
         interests of the Trust and except that no such indemnification shall be
         made in respect of any claim, issue or matter as to which such Company
         Indemnified Person shall have been adjudged to be liable to the Trust
         unless and only to the extent that the Court of Chancery of Delaware or
         the court in which such action or suit was brought shall determine upon
         application that, despite the adjudication of liability but in view of
         all the circumstances of the case, such person is fairly and reasonably
         entitled to indemnity for such expenses which such Court of Chancery or
         such other court shall deem proper.

                  (iii) To the extent that a Company Indemnified Person shall be
         successful on the merits or otherwise (including dismissal of an action
         without prejudice or the settlement of an action without admission of
         liability) in defense of any action, suit or proceeding referred to in
         paragraphs (i) and (ii) of this Section 10.4(a), or in defense of any
         claim, issue or matter therein, he shall be indemnified, to the full
         extent permitted by law, against expenses (including attorneys' fees)
         actually and reasonably incurred by him in connection therewith.

                  (iv) Any indemnification under paragraphs (i) and (ii) of this
         Section 10.4(a) (unless ordered by a court) shall be made by the
         Debenture Issuer only as authorized in the specific case upon a
         determination that indemnification of the Company Indemnified Person is
         proper in the circumstances because he has met the applicable standard
         of conduct set forth in paragraphs (i) and (ii). Such determination
         shall be made (1) by the Regular Trustees by a majority vote of a
         quorum consisting of such Regular Trustees who were not parties to such
         action, suit or proceeding, (2) if such a quorum is not obtainable, or,
         even if obtainable, if a quorum of disinterested Regular Trustees so
         directs, by independent legal counsel in a written opinion, or (3) by
         the Common Security Holder of the Trust.

                  (v) Expenses (including attorneys' fees) incurred by a Company
         Indemnified Person in defending a civil, criminal, administrative or
         investigative action, suit or proceeding referred to in paragraphs (i)
         and (ii) of this Section






                                       43

<PAGE>   49



         10.4(a) shall be paid by the Debenture Issuer in advance of the final
         disposition of such action, suit or proceeding upon receipt of an
         undertaking by or on behalf of such Company Indemnified Person to repay
         such amount if it shall ultimately be determined that he is not
         entitled to be indemnified by the Debenture Issuer as authorized in
         this Section 10.4(a). Notwithstanding the foregoing, no advance shall
         be made by the Debenture Issuer if a determination is reasonably and
         promptly made (i) by the Regular Trustees by a majority vote of a
         quorum of disinterested Regular Trustees, (ii) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Regular Trustees so directs, by independent legal counsel in a written
         opinion or (iii) the Common Security Holder of the Trust, that, based
         upon the facts known to the Regular Trustees, counsel or the Common
         Security Holder at the time such determination is made, such Company
         Indemnified Person acted in bad faith or in a manner that such person
         did not believe to be in or not opposed to the best interests of the
         Trust, or, with respect to any criminal proceeding, that such Company
         Indemnified Person believed or had reasonable cause to believe his
         conduct was unlawful. In no event shall any advance be made in
         instances where the Regular Trustees, independent legal counsel or
         Common Security Holder reasonably determine that such person
         deliberately breached his duty to the Trust or its Common or Preferred
         Security Holders.

                  (vi) The indemnification and advancement of expenses provided
         by, or granted pursuant to, the other paragraphs of this Section
         10.4(a) shall not be deemed exclusive of any other rights to which
         those seeking indemnification and advancement of expenses may be
         entitled under any agreement, vote of stockholders or disinterested
         directors of the Debenture Issuer or Preferred Security Holders of the
         Trust or otherwise, both as to action in his official capacity and as
         to action in another capacity while holding such office. All rights to
         indemnification under this Section 10.4(a) shall be deemed to be
         provided by a contract between the Debenture Issuer and each Company
         Indemnified Person who serves in such capacity at any time while this
         Section 10.4(a) is in effect. Any repeal or modification of this
         Section 10.4(a) shall not affect any rights or obligations then
         existing.

                  (vii) The Debenture Issuer or the Trust may purchase and
         maintain insurance on behalf of any person who is or was a Company
         Indemnified Person against any liability asserted against him and
         incurred by him in any such capacity, or arising out of his status as
         such, whether or not the Debenture Issuer would have the power to
         indemnify him against such liability under the provisions of this
         Section 10.4(a).

                  (viii) For purposes of this Section 10.4(a), references to
         "the Trust" shall include, in addition to the resulting or surviving
         entity, any constituent entity (including any constituent of a
         constituent) absorbed in a consolidation or merger, so that any person
         who is or was a director, trustee, officer or employee of such
         constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee or agent
         of another entity, shall stand in the same position under the
         provisions of this Section 10.4(a) with respect to the resulting or
         surviving entity as he would have with respect to such constituent
         entity if its separate existence had continued.

                  (ix) The indemnification and advancement of expenses provided
         by, or granted pursuant to, this Section 10.4(a) shall, unless
         otherwise provided when authorized or ratified, continue as to a person
         who has ceased to be a Company Indemnified Person and shall inure to
         the benefit of the heirs, executors and administrators of such a
         person.

                  (b) The Debenture Issuer agrees to indemnify the (i)
Institutional Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the
Institutional Trustee and the Delaware Trustee, and (iv) any officers,
directors, shareholders, members, partners, employees, representatives,
custodians, nominees or agents of the Institutional Trustee and the Delaware
Trustee (each of the Persons in (i) through (iv) being referred to as a
"Fiduciary Indemnified Person") for, and to hold each Fiduciary Indemnified
Person harmless against, any loss, liability or expense incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration or the trust or trusts hereunder, including the
costs and expenses (including reasonable legal fees and expenses) of defending
itself against or investigating any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder. The obligation
to indemnify as set forth in this Section 10.4(b) shall survive the satisfaction
and discharge of this Declaration.

SECTION 10.5      Outside Businesses.

                  Any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional Trustee may 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
Securities shall have no rights by virtue of this Declaration 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. No Covered Person, the Sponsor, the Delaware
Trustee, or the Institutional Trustee shall be obligated to pres-





                                       45

<PAGE>   51



ent 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 any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional 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 Covered Person, the Delaware
Trustee and the Institutional Trustee may engage or be interested in any
financial or other transaction with the Sponsor or any Affiliate of the Sponsor,
or may act as depositary for, trustee or agent for, or act on any committee or
body of holders of, securities or other obligations of the Sponsor or its
Affiliates.

                                   ACCOUNTING

SECTION 11.1      Fiscal Year.

                  The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

SECTION 11.2      Certain Accounting Matters.

                  (a) At all times during the existence of the Trust, the
Regular Trustees shall keep, or cause to be kept, full books of account, records
and supporting documents, which shall reflect in reasonable detail, each
transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year of the Trust by a firm of independent certified public
accountants selected by the Regular Trustees.

                  (b) The Regular Trustees shall cause to be prepared and
delivered to each of the Holders of Securities, within 90 days after the end of
each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss;

                  (c) The Regular Trustees shall cause to be duly prepared and
delivered to each of the Holders of Securities, any annual United States federal
income tax information statement, required by the Code, containing such
information with regard to the Securities held by each Holder as is required by
the Code and the Treasury Regulations. Notwithstanding any right under the Code
to deliver any such statement at a later date, the Regular






                                       46

<PAGE>   52



Trustees shall endeavor to deliver all such statements within 30 days after the
end of each Fiscal Year of the Trust.

                  (d) The Regular Trustees shall cause to be duly prepared and
filed with the appropriate taxing authority, an annual United States federal
income tax return, on a Form 1041 or such other form required by United States
federal income tax law, and any other annual income tax returns required to be
filed by the Regular Trustees on behalf of the Trust with any state or local
taxing authority.

SECTION 11.3      Banking.

                  The Trust shall maintain one or more bank accounts in the name
and for the sole benefit of the Trust; provided, however, that all payments of
funds in respect of the Debentures held by the Institutional Trustee shall be
made directly to the Institutional Trustee Account and no other funds of the
Trust shall be deposited in the Institutional Trustee Account. The sole
signatories for such accounts shall be designated by the Regular Trustees;
provided, however, that the Institutional Trustee shall designate the
signatories for the Institutional Trustee Account.

SECTION 11.4      Withholding.

                  The Trust and the Regular Trustees shall comply with all
withholding requirements under United States federal, state and local law. The
Trust shall request, and the Holders shall provide to the Trust, such forms or
certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably be
requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations. The Regular Trustees shall file
required forms with applicable jurisdictions and, unless an exemption from
withholding is properly established by a Holder, shall remit amounts withheld
with respect to the Holder to applicable jurisdictions. To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to distributions or allocations to any Holder, the amount withheld shall
be deemed to be a distribution in the amount of the withholding to the Holder.
In the event of any claimed over withholding, Holders shall be limited to an
action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

                             AMENDMENTS AND MEETINGS

SECTION 12.1      Amendments.

                  (b)        no amendment shall be made, and any such purported
amendment shall be void and ineffective:

                  (i) unless, in the case of any proposed amendment, the
         Institutional Trustee shall have first received an Officers'
         Certificate from each of the Trust and the Sponsor that such amendment
         is permitted by, and conforms to, the terms of this Declaration
         (including the terms of the Securities);

                  (ii) unless, in the case of any proposed amendment which

                  the Sponsor or the Trust) that such amendment is permitted by,
                  and conforms to, the terms of this Declaration (including the
                  terms of the Securities); and

                  (iii)      to the extent the result of such amendment would
         be to:

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

                        (B)    reduce or otherwise adversely affect the
                  powers of the Institutional Trustee in contravention of
                  the Trust Indenture Act; or

                        (C)    cause the Trust to be deemed to be an Investment
                  Company required to be registered under the Investment Company
                  Act;

                  (c)   at such time after the Trust has issued any Securities
that remain outstanding, any amendment that would adversely affect the rights,
privileges or preferences of any Holder of Securities may be effected only with
such additional requirements as may be set forth in the terms of such

SECTION 12.2      Meetings of the Holders of Securities; Action by
                  Written Consent.

                  (a) Meetings of the Holders of any class of Securities may be
called at any time by the Regular Trustees (or as provided in the terms of the
Securities) to consider and act on any matter on which Holders of such class of
Securities are entitled to act under the terms of this Declaration, the terms of
the Securities or the rules of any stock exchange on which the Preferred
Securities are listed or admitted for trading. The Regular Trustees shall call a
meeting of the Holders of such class if directed to do so by the Holders of at
least 10% in liquidation amount of such class of Securities. Such direction
shall be given by delivering to the Regular Trustees one or more calls in a
writing stating that the signing Holders of Securities wish to call a meeting
and indicating the general or specific purpose for which the meeting is to be
called. Any Holders of Securities calling a meeting shall specify in writing the
Security Certificates held by the Holders of Securities exercising the right to
call a meeting and only those Securities specified shall be counted for purposes
of determining whether the required percentage set forth in the second sentence
of this paragraph has been met.

                  (b)   Except to the extent otherwise provided in the
terms of the Securities, the following provisions shall apply to
meetings of Holders of Securities:

                  (i) notice of any such meeting shall be given to all the
         Holders of Securities having a right to vote thereat at least 7 days
         and not more than 60 days before the date of such meeting. Whenever a
         vote, consent or approval of the Holders of Securities is permitted or
         required under this Declaration or the rules of any stock exchange on
         which the Preferred Securities are listed or admitted for trading, such
         vote, consent or approval may be given at a meeting of the Holders of
         Securities. Any action that may be taken at a meeting of the Holders of
         Securities may be taken without a meeting if a consent in writing
         setting forth the action so taken is signed by the Holders of
         Securities owning not less than the minimum amount of Securities in
         liquidation amount that would be necessary to authorize or take such
         action at a meeting at which all Holders of Securities having a right
         to vote thereon were present and voting. Prompt notice of the taking of
         action without a meeting shall be given to the Holders of Securities
         entitled to vote who have not consented in writing. The Regular
         Trustees may specify that any written ballot submitted to the Security
         Holder for the purpose of taking any action without a meeting shall be
         returned to the Trust within the time specified by the Regular
         Trustees;

         for it by proxy on all matters in which a Holder of Securities is
         entitled to participate, including waiving notice of any meeting, or
         voting or participating at a meeting. No proxy shall be valid after the
         expiration of 11 months from the date thereof unless otherwise provided
         in the proxy. Every proxy shall be revocable at the pleasure of the
         Holder of Securities executing it. Except as otherwise provided herein,
         all matters relating to the giving, voting or validity of proxies shall
         be governed by the General Corporation Law of the State of Delaware
         relating to proxies, and judicial interpretations thereunder, as if the
         Trust were a Delaware corporation and the Holders of the Securities
         were stockholders of a Delaware corporation;

                  (iii)  each meeting of the Holders of the Securities
         shall be conducted by the Regular Trustees or by such other
         Person that the Regular Trustees may designate; and

                  (iv)  unless the Business Trust Act, this Declaration, the
         terms of the Securities, the Trust Indenture Act or the listing rules
         of any stock exchange on which the Preferred Securities are then listed
         or trading, otherwise provides, the Regular Trustees, in their sole
         discretion, shall establish all other provisions relating to meetings
         of Holders of Securities, including notice of the time, place or
         purpose of any meeting at which any matter is to be voted on by any
         Holders of Securities, waiver of any such notice, action by consent
         without a meeting, the establishment of a record date, quorum
         requirements, voting in person or by proxy or any other matter with

                                    TERMS OF
                   ___% TRUST ORIGINATED PREFERRED SECURITIES
                     ___% TRUST ORIGINATED COMMON SECURITIES


                  Pursuant to Section 7.1 of the Amended and Restated
Declaration of Trust, dated as of _______, 1996 (as amended from time to time,
the "Declaration"), the designation, rights, privileges, restrictions,
preferences and other terms and provisions of the Preferred Securities and the
Common Securities are set out below (each capitalized term used but not defined
herein has the meaning set forth in the Declaration or, if not defined in such
Declaration, as defined in the Prospectus referred to below):

                  1.       Designation and Number.

                  (a) Preferred Securities. [                  ] Pre- 
ferred Securities of the Trust with an aggregate liquidation amount with 
respect to the assets of the Trust of [              ] dollars ($[            ])
and a liquidation amount with respect to the assets of the Trust of $25 per 
preferred security, are hereby designated for the purposes of identification 
only as "_____% Trust Originated Preferred Securities(SM) ('TOPrS'(SM))" (
the "Preferred Securities"). The Preferred Security Certificates evidencing the 
Preferred Securities shall be substantially in the form of Exhibit A-1 to the 
Declaration, with such changes and additions thereto or deletions therefrom as
may be required by ordinary usage, custom or practice or to conform to the 
rules of any stock exchange on which the Preferred Securities are listed.

                  (b) Common Securities. [             ] Common Securities of 
the Trust with an aggregate liquidation amount with respect to the assets of 
the Trust of [           ] dollars ($[          ]) and a liquidation amount 
with respect to the assets of the Trust of $25 per common security, are hereby
designated for the purposes of identification only as "______% Trust Originated
Common Securities" (the "Common Securities"). The Common Security Certificates
evidencing the Common Securities shall be substantially in the form of Exhibit
A-2 to the Declaration, with such changes and additions thereto or deletions
therefrom as may be required by ordinary usage, custom or practice.

                  2.       Distributions.

                  (a) Distributions payable on each Security will be fixed at a
rate per annum of ______% (the "Coupon Rate") of the stated liquidation amount
of $25 per Security, such rate being





                                       I-1

<PAGE>   63



the rate of interest payable on the Debentures to be held by the Institutional
Trustee. Distributions in arrears for more than one quarter will bear interest
thereon compounded quarterly at the Coupon Rate (to the extent permitted by
applicable law). The term "Distributions" as used herein includes such cash
distributions and any such interest payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Institutional Trustee and to the extent the
Institutional Trustee has funds available therefor. The amount of Distributions
payable for any period will be computed for any full quarterly Distribution
period on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly Distribution period for which Distributions
are computed, Distributions will be computed on the basis of the actual number
of days elapsed per 90-day quarter.

                  (b) Distributions on the Securities will be cumulative, will
accrue from ________, 1996, and will be payable quarterly in arrears, on [March
31, June 30, September 30, and December 31] of each year, commencing on _______,
1996, except as otherwise described below. The Debenture Issuer has the right
under the Indenture to defer payments of interest by extending the interest
payment period from time to time on the Debentures for a period not exceeding 20
consecutive quarters or extend beyond the maturity date of the Debentures (each
an "Extension Period"), during which Extension Period no interest shall be due
and payable on the Debentures, provided that no Extension Period shall last
beyond the date of maturity of the Debentures. As a consequence of such
deferral, Distributions will also be deferred. Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period. Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity of
the Debentures. Payments of accrued Distributions will be payable to Holders as
they appear on the books and records of the Trust on the first record date after
the end of the Extension Period. Upon the termination of any Extension Period
and the payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

                  (c) Distributions on the Securities will be payable to the
Holders thereof as they appear on the books and records of the Trust on the
relevant record dates. While the Preferred Securities remain in book-entry only
form, the relevant record dates shall be one Business Day prior to the relevant
payment dates which payment dates correspond to the interest payment dates on
the Debentures. Subject to any applicable laws and





                                       I-2

<PAGE>   64



regulations and the provisions of the Declaration, each such payment in respect
of the Preferred Securities will be made as described under the heading
"Description of the Preferred Securities -- Book-Entry Only Issuance -- The
Depository Trust Company" in the Prospectus Supplement dated______, 1996, to the
Prospectus dated ______, 1996 (together, the "Prospectus"), of the Trust
included in the Registration Statement on Form S-3 of the Sponsor, the Trust and
certain other business trusts. The relevant record dates for the Common
Securities shall be the same record date as for the Preferred Securities. If the
Preferred Securities shall not continue to remain in book-entry only form, the
relevant record dates for the Preferred Securities, shall conform to the rules
of any securities exchange on which the securities are listed and, if none,
shall be selected by the Regular Trustees, which dates shall be at least one
Business Day but less than 60 Business Days before the relevant payment dates,
which payment dates correspond to the interest payment dates on the Debentures.
Distributions payable on any Securities that are not punctually paid on any
Distribution payment date, as a result of the Debenture Issuer having failed to
make a payment under the Debentures, will cease to be payable to the Person in
whose name such Securities are registered on the relevant record date, and such
defaulted Distribution will instead be payable to the Person in whose name such
Securities are registered on the special record date or other specified date
determined in accordance with the Indenture. If any date on which Distributions
are payable on the Securities is not a Business Day, then payment of the
Distribution 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 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 such date.

                  (d) In the event that there is any money or other property
held by or for the Trust that is not accounted for hereunder, such property
shall be distributed Pro Rata (as defined herein) among the Holders of the
Securities.

                  3.       Liquidation Distribution Upon Dissolution.

                  In the event of any voluntary or involuntary dissolution,
winding-up or termination of the Trust, the Holders of the Securities on the
date of the dissolution, winding-up or termination, as the case may be, will be
entitled to receive out of the assets of the Trust available for distribution to
Holders of Securities after satisfaction of liabilities of creditors an amount
equal to the aggregate of the stated liquidation amount of $25 per Security plus
accrued and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"), unless, in connection with such
dissolution, winding-up or termination, Debentures in an aggregate stated
principal






                                       I-3

<PAGE>   65



amount equal to the aggregate stated liquidation amount of such Securities, with
an interest rate equal to the Coupon Rate of, and bearing accrued and unpaid
interest in an amount equal to the accrued and unpaid Distributions on, such
Securities, shall be distributed on a Pro Rata basis to the Holders of the
Securities in exchange for such Securities.

                  If, upon any such dissolution, 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 the Securities shall be paid on a Pro Rata basis.

                  4.       Redemption and Distribution.

                  (a) Upon the repayment of the Debentures in whole or in part,
whether at maturity or upon redemption (either at the option of the Debenture
Issuer or pursuant to a Tax Event as described below), the proceeds from such
repayment or payment shall be simultaneously applied to redeem Securities having
an aggregate liquidation amount equal to the aggregate principal amount of the
Debentures so repaid or redeemed at a redemption price of $25 per Security plus
an amount equal to accrued and unpaid Distributions thereon at the date of the
redemption, payable in cash (the "Redemption Price"). Holders will be given not
less than 30 nor more than 60 days notice of such redemption.

                  (b) If fewer than all the outstanding Securities are to be so
redeemed, the Common Securities and the Preferred Securities will be redeemed
Pro Rata and the Preferred Securities to be redeemed will be as described in
Section 4(f)(ii) below.

                  (c) If, at any time, a Tax Event (as defined below) shall
occur and be continuing the Regular Trustees shall, except in certain limited
circumstances described in this Section 4(c), dissolve the Trust and, after
satisfaction of creditors, cause Debentures held by the Institutional Trustee,
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the Coupon Rate of, and accrued
and unpaid interest equal to accrued and unpaid Distributions on, and having the
same record date for payment as the Securities, to be distributed to the Holders
of the Securities in liquidation of such Holders' interests in the Trust on a
Pro Rata basis, within 90 days following the occurrence of such Tax Event (the
"90 Day Period"); provided, however, that, as a condition of such dissolution
and distribution, the Regular Trustees shall have received an opinion of a
nationally recognized independent tax counsel experienced in such matters (a "No
Recognition Opinion"), which opinion may rely on published revenue rulings of
the Internal Revenue Service, to the effect that the Holders of the Securities
will not recognize any gain or loss for United States federal income tax
purposes as a result of the dissolution of the






                                       I-4

<PAGE>   66



Trust and the distribution of Debentures, and provided, further, that, if at the
time there is available to the Trust the opportunity to eliminate, within the 90
Day Period, the Tax Event by taking some ministerial action, such as filing a
form or making an election, or pursuing some other similar reasonable measure
that has no adverse effect on the Trust, the Debenture Issuer, the Sponsor or
the Holders of the Securities ("Ministerial Action"), the Trust will pursue such
Ministerial Action in lieu of dissolution.

                  If in the event of a Tax Event, (i) after receipt of a Tax
Event Opinion (as defined hereinafter) by the Regular Trustees, the Debenture
Issuer has received an opinion (a "Redemption Tax Opinion") of a nationally
recognized independent tax counsel experienced in such matters that, as a result
of a Tax Event, there is more than an insubstantial risk that the Debenture
Issuer would be precluded from deducting the interest on the Debentures for
United States federal income tax purposes even after the Debentures were
distributed to the Holders of Securities in liquidation of such Holders'
interests in the Trust as described in this Section 4(c), or (ii) the Regular
Trustees shall have been informed by such tax counsel that a No Recognition
Opinion cannot be delivered to the Trust, the Debenture Issuer shall have the
right at any time, upon not less than 30 nor more than 60 days notice, to redeem
the Debentures in whole or in part for cash within 90 days following the
occurrence of such Tax Event, and, following such redemption, Securities with an
aggregate liquidation amount equal to the aggregate principal amount of the
Debentures so redeemed shall be redeemed by the Trust at the Redemption Price on
a Pro Rata basis; provided, however, that, if at the time there is available to
the Debenture Issuer or the Trust the opportunity to eliminate, within such 90
day period, the Special Event by taking some Ministerial Action, the Trust or
the Debenture Issuer will pursue such Ministerial Action in lieu of redemption.

                  "Tax Event" means that the Regular Trustees shall have
received an opinion of a nationally recognized independent tax counsel
experienced in such matters (a "Dissolution Tax Opinion") to the effect that on
or after the date of the Prospectus Supplement, as a result of (a) any amendment
to, clarification of 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 affecting taxation, (b) any
judicial decision, official administrative pronouncement, ruling, regulatory
procedure, notice or announcement, including any notice or announcement of
intent to adopt such procedures or regulations (an "Administrative Action") or
(c) any amendment to, clarification of, or change in the official position or
the interpretation of such Administrative Action or judicial decision that
differs from the theretofore generally accepted position, in each case, by any
legislative






                                       I-5

<PAGE>   67



body, court, governmental authority or regulatory body, irrespective of the
manner in which such amendment, clarification or change is made known, which
amendment, clarification, or change is effective or such pronouncement or
decision is announced, in each case, on or after, the first date of issuance of
the Securities, there is more than an insubstantial risk that (i) the Trust is
or will be within 90 days of the date thereof, subject to United States federal
income tax with respect to interest accrued or received on the Debentures, (ii)
the Trust is, or will be within 90 days of the date thereof, subject to more
than a de minimis amount of taxes, duties or other governmental charges, or
(iii) interest payable by the Debenture Issuer to the Trust on the Debentures is
not, or within 90 days of the date thereof will not be, deductible, in whole or
in part, by the Debenture Issuer for United States federal income tax purposes.

                  On and from the date fixed by the Regular Trustees for any
distribution of Debentures and dissolution of the Trust: (i) the Securities will
no longer be deemed to be outstanding, (ii) The Depository Trust Company (the
"Depository") or its nominee (or any successor Clearing Agency or its nominee),
as the record Holder of the Preferred Securities, will receive a registered
global certificate or certificates representing the Debentures to be delivered
upon such distribution and any certificates representing Securities, except for
certificates representing Preferred Securities held by the Depository or its
nominee (or any successor Clearing Agency or its nominee), will be deemed to
represent beneficial interests in the Debentures having an aggregate principal
amount equal to the aggregate stated liquidation amount of, with an interest
rate identical to the Coupon Rate of, and accrued and unpaid interest equal to
accrued and unpaid Distributions on such Securities until such certificates are
presented to the Debenture Issuer or its agent for transfer or reissue.

                  (d)      The Trust may not redeem fewer than all the 
outstanding Securities unless all accrued and unpaid Distributions have been
paid on all Securities for all quarterly Distribution periods terminating on or
before the date of redemption.

                  (e)      If the Debentures are distributed to holders of the
Securities, pursuant to the terms of the Indenture, the Debenture Issuer will
use its best efforts to have the Debentures listed on the New York Stock
Exchange or on such other exchange as the Preferred Securities were listed
immediately prior to the distribution of the Debentures.

                  (f)      "Redemption or Distribution Procedures."

                  (i)      Notice of any redemption of, or notice of distri-
         bution of Debentures in exchange for the Securities (a "Re-
         demption/Distribution Notice") will be given by the Trust by






                                       I-6

<PAGE>   68



         mail to each Holder of Securities to be redeemed or exchanged not fewer
         than 30 nor more than 60 days before the date fixed for redemption or
         exchange thereof which, in the case of a redemption, will be the date
         fixed for redemption of the Debentures. For purposes of the calculation
         of the date of redemption or exchange and the dates on which notices
         are given pursuant to this Section 4(f)(i), a Redemption/ Distribution
         Notice shall be deemed to be given on the day such notice is first
         mailed by first-class mail, postage prepaid, to Holders of Securities.
         Each Redemption/Distribution Notice shall be addressed to the Holders
         of Securities at the address of each such Holder appearing in the books
         and records of the Trust. No defect in the Redemption/Distribution
         Notice or in the mailing of either thereof with respect to any Holder
         shall affect the validity of the redemption or exchange proceedings
         with respect to any other Holder.

                  (ii) In the event that fewer than all the outstanding
         Securities are to be redeemed, the Securities to be redeemed shall be
         redeemed Pro Rata from each Holder of Preferred Securities, it being
         understood that, in respect of Preferred Securities registered in the
         name of and held of record by the Depository or its nominee (or any
         successor Clearing Agency or its nominee) or any nominee, the
         distribution of the proceeds of such redemption will be made to each
         Clearing Agency Participant (or Person on whose behalf such nominee
         holds such securities) in accordance with the procedures applied by
         such agency or nominee.

                  (iii) If Securities are to be redeemed and the Trust gives a
         Redemption/Distribution Notice, which notice may only be issued if the
         Debentures are redeemed as set out in this Section 4 (which notice will
         be irrevocable), then (A) while the Preferred Securities are in
         book-entry only form, with respect to the Preferred Securities, by
         12:00 noon, New York City time, on the redemption date, provided that
         the Debenture Issuer has paid the Institutional Trustee a sufficient
         amount of cash in connection with the related redemption or maturity of
         the Debentures, the Institutional Trustee will deposit irrevocably with
         the Depository or its nominee (or successor Clearing Agency or its
         nominee) funds sufficient to pay the applicable Redemption Price with
         respect to the Preferred Securities and will give the Depository
         irrevocable instructions and authority to pay the Redemption Price to
         the Holders of the Preferred Securities, and (B) with respect to
         Preferred Securities issued in definitive form and Common Securities,
         provided that the Debenture Issuer has paid the Institutional Trustee a
         sufficient amount of cash in connection with the related redemption or
         maturity of the Debentures, the Institutional Trustee will pay the
         relevant Redemption Price to the Holders of






                                       I-7

<PAGE>   69



         such Securities by check mailed to the address of the relevant Holder
         appearing on the books and records of the Trust on the redemption date.
         If a Redemption/Distribution Notice shall have been given and funds
         deposited as required, if applicable, then immediately prior to the
         close of business on the date of such deposit, or on the redemption
         date, as applicable, distributions will cease to accrue on the
         Securities so called for redemption and all rights of Holders of such
         Securities so called for redemption will cease, except the right of the
         Holders of such Securities to receive the Redemption Price, but without
         interest on such Redemption Price. Neither the Regular Trustees nor the
         Trust shall be required to register or cause to be registered the
         transfer of any Securities that have been so called for redemption. If
         any date fixed for redemption of Securities 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 fixed for redemption. If
         payment of the Redemption Price in respect of any Securities is
         improperly withheld or refused and not paid either by the Institutional
         Trustee or by the Sponsor as guarantor pursuant to the relevant
         Securities Guarantee, Distributions on such Securities will continue to
         accrue from the original redemption date to the actual date of payment,
         in which case the actual payment date will be considered the date fixed
         for redemption for purposes of calculating the Redemption Price.

                  (iv) Redemption/Distribution Notices shall be sent by the
         Regular Trustees on behalf of the Trust to (A) in respect of the
         Preferred Securities, the Depository or its nominee (or any successor
         Clearing Agency or its nominee) if the Global Certificates have been
         issued or, if Definitive Preferred Security Certificates have been
         issued, to the Holder thereof, and (B) in respect of the Common
         Securities to the Holder thereof.

                  (v) Subject to the foregoing and applicable law (including,
         without limitation, United States federal securities laws), provided
         the acquiror is not the Holder of the Common Securities or the obligor
         under the Indenture, the Sponsor or any of 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.

                  5.       Voting Rights - Preferred Securities.

                  (a)      Except as provided under Sections 5(b) and 7 and
as otherwise required by law and the Declaration, the Holders of
the Preferred Securities will have no voting rights.

                  (b)      Subject to the requirements set forth in this 
paragraph, the Holders of a majority in aggregate liquidation amount of the
Preferred Securities, voting separately as a class may direct the time, method,
and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including the right to direct the
Institutional Trustee, as holder of the Debentures, to (i) exercise the
remedies available under the Indenture conducting any proceeding for any remedy
available to the Debenture Trustee, or exercising any trust or power conferred
on the Debenture Trustee with respect to the Debentures, (ii) waive any past
default and its consequences that is waivable under Section ___ of the
Indenture, or (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable, provided,
however, that, where a consent under the Indenture would require the consent or
act of the Holders of greater than a majority of the Holders in principal
amount of Debentures affected thereby, (a "Super Majority"), the Institutional
Trustee may only give such consent or take such action at the written direction
of the Holders of at least the proportion in liquidation amount of the
Preferred Securities which the relevant Super Majority represents of the
aggregate principal amount of the Debentures outstanding. The Institutional
Trustee shall not revoke any action previously authorized or approved by a vote
of the Holders of the Preferred Securities. Other than with respect to
directing the time, method and place of conducting any remedy available to the
Institutional Trustee or the Debenture Trustee as set forth above, the
Institutional Trustee shall not take any action in accordance with the
directions of the Holders of the Preferred Securities under this paragraph
unless the Institutional Trustee has obtained an opinion of tax counsel to the
effect that for the purposes of United States federal income tax the Trust will
not be classified as other than a grantor trust on account of such action. If a
Declaration Event of Default has occurred and is continuing and such event is
attributable to the failure of the Debenture Issuer to pay interest or
principal on the Debentures on the date such interest or principal is otherwise
payable (or in the case of redemption, on the redemption date), then a holder
of Preferred Securities may directly institute a proceeding for enforcement of
payment to such Holder of the principal of or interest on the Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder (a "Direct Action") on or after the respective due
date specified in the Debentures. In connection with such Direct Action, the
rights of






                                       I-9

<PAGE>   71



the holders of the Common Securities Holder will be subrogated to the rights of
such holder of Preferred Securities to the extent of any payment made by the
Issuer to such holder of Preferred Securities in such Direct Action. Except as
provided in the preceding sentences, the Holders of Preferred Securities will
not be able to exercise directly any other remedy available to the holders of
the Debentures.

                  Any approval or direction of Holders of Preferred Securities
may be given at a separate meeting of Holders of Preferred Securities convened
for such purpose, at a meeting of all of the Holders of Securities in the Trust
or pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Preferred Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Preferred Securities. Each such notice
will include a statement setting forth (i) the date of such meeting or the date
by which such action is to be taken, (ii) a description of any resolution
proposed for adoption at such meeting on which such Holders are entitled to vote
or of such matter upon which written consent is sought and (iii) instructions
for the delivery of proxies or consents.

                  No vote or consent of the Holders of the Preferred Securities
will be required for the Trust to redeem and cancel Preferred Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                  Notwithstanding that Holders of Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Preferred Securities that are owned by the Sponsor or any Affiliate of
the Sponsor shall not be entitled to vote or consent and shall, for purposes of
such vote or consent, be treated as if they were not outstanding.

                  6.       Voting Rights - Common Securities.

                  (a)      Except as provided under Sections 7(b), (c) and 8
as otherwise required by law and the Declaration, the Holders of
the Common Securities will have no voting rights.

                  (b)      The Holders of the Common Securities are entitled, in
accordance with Article V of the Declaration, to vote to appoint, remove or
replace any Trustee or to increase or decrease the number of Trustees.

                  (c)      Subject to Section 2.6 of the Declaration and only
after the Event of Default with respect to the Preferred Securities has been
cured, waived, or otherwise eliminated and subject to the requirements of the
second to last sentence of this paragraph, the Holders of a Majority in
liquidation amount of the






                                      I-10

<PAGE>   72



Common Securities, voting separately as a class, may direct the time, method,
and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including (i) directing the time,
method, place of conducting any proceeding for any remedy available to the
Debenture Trustee, or exercising any trust or power conferred on the Debenture
Trustee with respect to the Debentures, (ii) waive any past default and its
consequences that is waivable under Section ____ of the Indenture, or (iii)
exercise any right to rescind or annul a declaration that the principal of all
the Debentures shall be due and payable, provided that, where a consent or
action under the Indenture would require the consent or act of the Holders of
greater than a majority in principal amount of Debentures affected thereby (a
"Super Majority"), the Institutional Trustee may only give such consent or take
such action at the written direction of the Holders of at least the proportion
in liquidation amount of the Common Securities which the relevant Super Majority
represents of the aggregate principal amount of the Debentures outstanding.
Pursuant to this Section 6(c), the Institutional Trustee shall not revoke any
action previously authorized or approved by a vote of the Holders of the
Preferred Securities. Other than with respect to directing the time, method and
place of conducting any remedy available to the Institutional Trustee or the
Debenture Trustee as set forth above, the Institutional Trustee shall not take
any action in accordance with the directions of the Holders of the Common
Securities under this paragraph unless the Institutional Trustee has obtained an
opinion of tax counsel to the effect that for the purposes of United States
federal income tax the Trust will not be classified as other than a grantor
trust on account of such action. If the Institutional Trustee fails to enforce
its rights under the Declaration, any Holder of Common Securities may institute
a legal proceeding directly against any Person to enforce the Institutional
Trustee's rights under the Declaration, without first instituting a legal
proceeding against the Institutional Trustee or any other Person.

                  Any approval or direction of Holders of Common Securities may
be given at a separate meeting of Holders of Common Securities convened for such
purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Common Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Common Securities. Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such Holders are entitled to vote or of
such matter upon which written consent is






                                      I-11

<PAGE>   73



sought and (iii) instructions for the delivery of proxies or consents.

                  No vote or consent of the Holders of the Common Securities
will be required for the Trust to redeem and cancel Common Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                  7.       Amendments to Declaration and Indenture.

                  (a) In addition to any requirements under Section 12.1 of the
Declaration, if any proposed amendment to the Declaration provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 of the Declaration, then the Holders of outstanding Securities
voting together as a single class, will be entitled to vote on such amendment or
proposal (but not on any other 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 Securities, affected thereby,
provided, however, if any amendment or proposal referred to in clause (i) above
would adversely affect only the Preferred Securities or only the Common
Securities, then only the affected 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 a Majority in liquidation amount of such class of
Securities.

                  (b) In the event the consent of the Institutional Trustee as
the holder of the Debentures is required under the Indenture with respect to any
amendment, modification or termination on the Indenture or the Debentures, the
Institutional Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination and shall
vote with respect to such amendment, modification or termination as directed by
a Majority in liquidation amount of the Securities voting together as a single
class; provided, however, that where a consent under the Indenture would require
the consent of the holders of greater than a majority in aggregate principal
amount of the Debentures (a "Super Majority"), the Institutional Trustee may
only give such consent at the direction of the Holders of at least the
proportion in liquidation amount of the Securities which the relevant Super
Majority represents of the aggregate principal amount of the Debentures
outstanding; provided, further, that the Institutional Trustee shall not take
any action in accordance with the directions of the Holders of the Securities
under this Section 7(b) unless the Institutional Trustee has obtained an opinion
of tax counsel to the effect that for the purposes of United States federal
income

tax the Trust will not be classified as other than a grantor trust on account of
such action.

                  8.       Pro Rata.

                  A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder
of Securities according to the aggregate liquidation amount of the Securities
held by the relevant Holder in relation to the aggregate liquidation amount of
all Securities outstanding unless, in relation to a payment, an Event of Default
under the Declaration has occurred and is continuing, in which case any funds
available to make such payment shall be paid first to each Holder of the
Preferred Securities pro rata according to the aggregate liquidation amount of
Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Preferred Securities, to
each Holder of Common Securities pro rata according to the aggregate liquidation
amount of Common Securities held by the relevant Holder relative to the
aggregate liquidation amount of all Common Securities outstanding.

                  9.       Ranking.

                  The Preferred Securities rank pari passu and payment thereon
shall be made Pro Rata with the Common Securities except that, where a
Declaration Event of Default occurs and is continuing the rights of Holders of
the Common Securities to payment in respect of Distributions and payments upon
liquidation, redemption and otherwise are subordinated to the rights to payment
of the Holders of the Preferred Securities.

                  10.      Listing.

                  The Regular Trustees shall use their best efforts to cause the
Preferred Securities to be listed for quotation on the New York Stock Exchange,
Inc.

                  11.      Acceptance of Securities Guarantee and Indenture.

                  Each Holder of Preferred Securities and Common Securities, by
the acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.

                  12.      No Preemptive Rights.

                  The Holders of the Securities shall have no preemptive rights
to subscribe for any additional securities.

                          [FORM OF REVERSE OF SECURITY]

                  Distributions payable on each Preferred Security will be fixed
at a rate per annum of ______% (the "Coupon Rate") of the stated liquidation
amount of $__ per Preferred Security, such rate being the rate of interest
payable on the Debentures to be held by the Institutional Trustee. Distributions
in arrears for more than one quarter will bear interest thereon compounded
quarterly at the Coupon Rate (to the extent permitted by applicable law). The
term "Distributions" as used herein includes such cash distributions and any
such interest payable unless otherwise stated. A Distribution is payable only to
the extent that payments are made in respect of the Debentures held by the
Institutional Trustee and to the extent the Institutional Trustee has funds
available therefor. The amount of Distributions payable for any period will be
computed for any full quarterly Distribution period on the basis of a 360-day
year of twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 90-day quarter.

                  Except as otherwise described below, distributions on the
Preferred Securities will be cumulative, will accrue from the date of original
issuance and will be payable quarterly in arrears, on [March 31, June 30,
September 30 and December 31] of each year, commencing on ________, 1996, to
[Holders of record fifteen (15) days prior to such payment dates, which payment
dates shall correspond to the interest payment dates on the Debentures.] The
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period from time to time on the Debentures for
a period not exceeding 20 consecutive quarters (each an "Extension Period"),
provided that no Extension Period shall last beyond the date of the maturity of
the Debentures and as a consequence of such deferral, Distributions will also be
deferred. Despite such deferral, quarterly Distributions will continue to accrue
with interest thereon (to the extent permitted by applicable law) at the Coupon
Rate compounded quarterly during any such Extension Period. Prior to the
termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters or extend beyond the maturity of the Debentures. Payments of accrued
Distributions will be payable to Holders as they appear on the books and records
of the Trust on the first record date after the end of the Extension Period.
Upon the termination of any Extension Period and the payment of all amounts then
due, the Debenture Issuer may commence a new Extension Period, subject to the
above requirements.

<PAGE>   83



                          [FORM OF REVERSE OF SECURITY]

                  Distributions payable on each Common Security will be fixed at
a rate per annum of ______% (the "Coupon Rate") of the stated liquidation amount
of $__ per Common Security, such rate being the rate of interest payable on the
Debentures to be held by the Institutional Trustee. Distributions in arrears for
more than one quarter will bear interest thereon compounded quarterly at the
Coupon Rate (to the extent permitted by applicable law). The term
"Distributions" as used herein includes such cash distributions and any such
interest payable unless otherwise stated. A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the
Institutional Trustee and to the extent the Institutional Trustee has funds
available therefor. The amount of Distributions payable for any period will be
computed for any full quarterly Distribution period on the basis of a 360-day
year of twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 90-day quarter.

                  Except as otherwise described below, distributions on the
Common Securities will be cumulative, will accrue from the date of original
issuance and will be payable quarterly in arrears, on [March 31, June 30,
September 30 and December 31] of each year, commencing on ________, 1996, to
Holders of record fifteen (15) days prior to such payment dates, which payment
dates shall correspond to the interest payment dates on the Debentures. The
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period from time to time on the Debentures for
a period not exceeding 20 consecutive quarters (each an "Extension Period"),
provided that no Extension Period shall last beyond the date of the maturity of
the Debentures and as a consequence of such deferral, Distributions will also be
deferred. Despite such deferral, quarterly Distributions will continue to accrue
with interest thereon (to the extent permitted by applicable law) at the Coupon
Rate compounded quarterly during any such Extension Period. Prior to the
termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters or extend beyond the maturity date of the Debentures. Payments of
accrued Distributions will be payable to Holders as they appear on the books and
records of the Trust on the first record date after the end of the Extension
Period. Upon the termination of any Extension Period and the payment of all
amounts then due, the Debenture Issuer may commence a new Extension Period,
subject to the above requirements.

Preferred Securities may, by vote, on behalf of the Holders of all of the

Preferred Securities and its consequences, provided that, if the underlying
Event of Default under the Indenture:

                 (i)        is not waivable under the Indenture, the Event of
         Default under the Declaration shall also not be waivable; or

                 (ii)       requires the consent or vote of greater than a
         majority in principal amount of the holders of the Debentures (a

Securities, as permitted by the Trust Indenture Act.  Upon such waiver, any
such default shall cease to exist, and any Event of Default with respect to the
Preferred Securities arising therefrom shall be deemed to have been cured, for
every purpose of this Declaration, but no such waiver shall extend to any
subsequent or other default or an Event of Default with respect to the
Preferred Securities or impair any right consequent thereon.  Any waiver by the
Holders of the Preferred Securities of an Event of Default with respect to the
Preferred Securities shall also be deemed to constitute a waiver by the Holders
of the Common Securities of any such Event of Default with respect to the
Common Securities for all purposes of this Declaration without any further act,
vote, or consent of the Holders of the Common Securities.

                 (b)        The Holders of a Majority in liquidation amount of

         the Holders of the Common Securities are deemed to have waived such
         Event of Default under the Declaration as provided below in this
         Section 2.6(b), the Event of Default under the Declaration shall also
         not be waivable; or





                                       10
<PAGE>   16
                 (ii)       requires the consent or vote of a Super Majority to
         be waived, except where the Holders of the Common Securities are
         deemed to have waived such Event of Default under the Declaration as
         provided below in this Section 2.6(b), the Event of Default under the
         Declaration may only be waived by the vote of the Holders of at least
         the proportion in liquidation amount of the Common Securities that the
         relevant Super Majority represents of the aggregate principal amount
         of the Debentures outstanding;

provided further, each Holder of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default with respect to the
Common Securities and its consequences until all Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated,
and until such Events of Default have been so cured, waived or otherwise
eliminated, the Institutional Trustee will be deemed to be acting solely on
behalf of the Holders of the Preferred Securities and only the Holders of the
Preferred Securities will have the right to direct the Institutional Trustee in
accordance with the terms of the Securities.  The foregoing provisions of this
Section 2.6(b) shall be in lieu of Sections  316(a)(1)(A) and 316(a)(1)(B) of
the Trust Indenture Act and such Sections  316(a)(1)(A) and 316(a)(1)(B) of the
Trust Indenture Act are hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act.  Subject to the foregoing
provisions of this Section 2.6(b), upon such waiver, any such default shall
cease to exist and any Event of Default with respect to the Common Securities
arising therefrom shall be deemed to have been cured for every purpose of this
Declaration, but no such waiver shall extend to any subsequent or other default
or Event of Default with respect to the Common Securities or impair any right
consequent thereon.

                 (c)        A waiver of an Event of Default under the Indenture

this Section 3.6 in a manner that is consistent with the purposes and functions
of the Trust set out in Section 3.3, and the Regular Trustees shall not take
any action that is inconsistent with the purposes and functions of the Trust
set forth in Section 3.3.

                 Subject to this Section 3.6, the Regular Trustees shall have

         holding the Debentures, but shall distribute all such proceeds to
         Holders of Securities pursuant to the terms of this Declaration and of
         the Securities;





                                       16

                 (a)        The legal title to the Debentures shall be owned by

                                       17
<PAGE>   23
         in the name of and under the exclusive control of the Institutional
         Trustee on behalf of the Holders of the Securities and, upon the
         receipt of payments of funds made in respect of the Debentures held by
         the Institutional Trustee, deposit such funds into the Institutional
         Trustee Account and make payments to the Holders of the Preferred
         Securities and Holders of the Common Securities from the Institutional
         Trustee Account in accordance with Section 6.1.  Funds in the
         Institutional Trustee Account shall be held uninvested until disbursed
         in accordance with this Declaration.  The Institutional Trustee
         Account shall be an account that is maintained with a banking
         institution the rating on whose long-term unsecured indebtedness is at
         least equal to the rating assigned to the Preferred Securities by a
         "nationally recognized statistical rating organization", as that term
         is defined for purposes of Rule 436(g)(2) under the Securities Act;

                 (ii)       engage in such ministerial activities as shall be
         necessary or appropriate to effect the redemption of the Preferred
         Securities and the Common Securities to the extent the Debentures are

                 (iii)      upon written notice of distribution issued by the
         Regular Trustees in accordance with the terms of the Securities,
         engage in such ministerial activities as shall be necessary or
         appropriate to effect the distribution of the Debentures to Holders of
         Securities upon the occurrence of certain special events (as may be
         defined in the terms of the Securities) arising from a change in law
         or a change in legal interpretation or other specified circumstances
         pursuant to the terms of the Securities.

                 (d)        The Institutional Trustee shall take all actions
and perform such duties as may be specifically required of the Institutional
Trustee pursuant to the terms of the Securities.

                 (e)        The Institutional Trustee shall take any Legal
Action which arises out of or in connection with an Event of Default of which a
Responsible Officer of the Institutional Trustee has actual knowledge or the
Institutional Trustee's duties and obligations under this Declaration or the
Trust Indenture Act; provided however, that if a Declaration Event of Default
has occurred and is continuing and such event is attributable to the failure of
the Debenture Issuer to pay interest or principal on the Debentures on the date
such interest or principal is otherwise payable (or in the case of redemption,
on the redemption date), then a Holder of Preferred Securities may directly
institute a proceeding for enforcement of payment to such Holder of the
principal of or interest on the Debentures having a principal amount equal to
the aggregate liquidation amount of the Preferred Securities of such Holder (a
"Direct





                                       18
<PAGE>   24
Action") on or after the respective due date specified in the Debentures.  In
connection with such Direct Action, the rights of the Holders of the Common
Securities Holder will be subrogated to the rights of such Holder of Preferred
Securities to the extent of any payment made by the Issuer to such Holder of
Preferred Securities in such Direct Action.  Except as provided in the
preceding sentences, the Holders of Preferred Securities will not be able to
exercise directly any other remedy available to the holders of the Debentures.

                 (f)        The Institutional Trustee shall not resign as a
Trustee unless either:

                 (i)        the Trust has been completely liquidated and the
         proceeds of the liquidation distributed to the Holders of Securities
         pursuant to the terms of the Securities; or

                 (ii)       a Successor Institutional Trustee has been
         appointed and has accepted that appointment in accordance with Section
         5.7.

                 (g)        The Institutional Trustee shall have the legal
power to exercise all of the rights, powers and privileges of a holder of
Debentures under the Indenture and, if an Event of Default actually known to a
Responsible Officer of the Institutional Trustee occurs and is continuing, the
Institutional Trustee shall, for the benefit of Holders of the Securities,
enforce its rights as holder of the Debentures subject to the rights of the
Holders pursuant to the terms of such Securities.

                 (h)        The Institutional Trustee may authorize one or more
Persons (each, a "Paying Agent") to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all securities and
any such Paying Agent shall comply with Section  317(b) of the Trust Indenture
Act.  Any Paying Agent may be removed by the Institutional Trustee at any time
and a successor Paying Agent or additional Paying Agents may be appointed at
any time by the Institutional Trustee.

                 (i)        Subject to this Section 3.8, the Institutional
Trustee shall have none of the duties, liabilities, powers or the authority of
the Regular Trustees set forth in Section 3.6.

                 The Institutional Trustee must exercise the powers set forth
in this Section 3.8 in a manner that is consistent with the purposes and
functions of the Trust set out in Section 3.3, and the Institutional Trustee
shall not take any action that is inconsistent with the purposes and functions
of the Trust set out in Section 3.3.

SECTION 3.9      Certain Duties and Responsibilities of the Institutional
                 Trustee.

                 (a)        The Institutional Trustee, before the occurrence of

have occurred, shall undertake to perform only such duties as are specifically
set forth in this Declaration and no implied covenants shall be read into this
Declaration against the Institutional Trustee.  In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6) of which a
Responsible Officer of the Institutional Trustee has actual knowledge, the
Institutional Trustee shall exercise such of the rights and powers vested in it
by this Declaration, 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 or her own affairs.

                 (b)        No provision of this Declaration shall be construed
to relieve the Institutional 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 an 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
                 Institutional Trustee shall be determined solely by the
                 express provisions of this Declaration and the Institutional
                 Trustee shall not be liable except for the performance of such
                 duties and obligations as are specifically set forth in this
                 Declaration, and no implied covenants or obligations shall be
                 read into this Declaration against the Institutional Trustee;
                 and

                            (B)     in the absence of bad faith on the part of
                 the Institutional Trustee, the Institutional Trustee may
                 conclusively rely, as to the truth of the statements and the
                 correctness of the opinions expressed therein, upon any

                 Trustee and conforming to the requirements of this
                 Declaration; but in the case of any such certificates or
                 opinions that by any provision hereof are specifically
                 required to be furnished to the Institutional Trustee, the
                 Institutional Trustee shall be under a duty to examine the
                 same to determine whether or not they conform to the
                 requirements of this Declaration;

                 (ii)       the Institutional Trustee shall not be liable for
         any error of judgment made in good faith by a Responsible Officer of
         the Institutional Trustee, unless it shall be

         proved that the Institutional Trustee was negligent in ascertaining
         the pertinent facts;

                 (iii)      the Institutional 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 Securities relating to the time,
         method and place of conducting any proceeding for any remedy available
         to the Institutional Trustee, or exercising any trust or power
         conferred upon the Institutional Trustee under this Declaration;

                 (iv)       no provision of this Declaration shall require the
         Institutional Trustee to expend or risk its own funds or otherwise
         incur personal financial liability in the performance of any of its
         duties or in the exercise of any of its rights or powers, if it shall
         have reasonable grounds for believing that the repayment of such funds
         or liability is not reasonably assured to it under the terms of this
         Declaration or indemnity reasonably satisfactory to the Institutional
         Trustee against such risk or liability is not reasonably assured to
         it;

                 (v)        the Institutional Trustee's sole duty with respect
         to the custody, safe keeping and physical preservation of the
         Debentures and the Institutional Trustee Account shall be to deal with
         such property in a similar manner as the Institutional Trustee deals
         with similar property for its own account, subject to the protections
         and limitations on liability afforded to the Institutional Trustee
         under this Declaration and the Trust Indenture Act;

                 (vi)       the Institutional Trustee shall have no duty or
         liability for or with respect to the value, genuineness, existence or
         sufficiency of the Debentures or the payment of any taxes or
         assessments levied thereon or in connection therewith;

                 (vii)      the Institutional Trustee shall not be liable for
         any interest on any money received by it except as it may otherwise
         agree with the Sponsor.  Money held by the Institutional Trustee need
         not be segregated from other funds held by it except in relation to
         the Institutional Trustee Account maintained by the Institutional
         Trustee pursuant to Section 3.8(c)(i) and except to the extent
         otherwise required by law; and

                 (viii) the Institutional Trustee shall not be responsible for
         monitoring the compliance by the Regular Trustees or the Sponsor with
         their respective duties under this Declaration, nor shall the

                 (b)        The Trust may, with the consent of the Regular
Trustees or, if there are more than two, a majority of the Regular Trustees and
without the consent of the Holders of the Securities, the Delaware Trustee or
the Institutional Trustee, consolidate, amalgamate, merge with or into, or be
replaced by a trust organized as such under the laws of any State; provided
that:

                 (i)        such successor entity (the "Successor Entity")
         either:

                            (A)     expressly assumes all of the obligations of
                 the Trust under the Securities; or

                            (B)     substitutes for the 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 with respect to Distributions and payments
                 upon liquidation, redemption and otherwise;

         Securities are listed, or any Successor Securities will be listed upon
         notification of issuance, on any national securities exchange or with

         or quoted;

<PAGE>   31
                 (iv)       such merger, consolidation, amalgamation or
         replacement does not cause the Preferred Securities (including any
         Successor Securities) to be downgraded by any nationally recognized
         statistical rating organization;

                 (v)        such merger, consolidation, amalgamation or
         replacement does not adversely affect the rights, preferences and
         privileges of the Holders of the  Securities (including any Successor
         Securities) in any material respect (other than with respect to any
         dilution of such Holders' interests in the Preferred Securities as a
         result of such merger, consolidation, amalgamation or replacement);

                 (vi)       such Successor Entity has a purpose identical to
         that of the Trust;

                 (vii)      prior to such merger, consolidation, amalgamation
         or replacement, the Sponsor has received an opinion of a nationally
         recognized independent counsel to the Trust experienced in such
         matters to the effect that:

                            (A)     such merger, consolidation, amalgamation or
                 replacement does not adversely affect the rights, preferences
                 and privileges of the Holders of the Securities (including any
                 Successor Securities) in any material respect (other than with
                 respect to any dilution of the Holders' interest in the new
                 entity); and

                            (B)     following such merger, consolidation,
                 amalgamation or replacement, neither the Trust nor the
                 Successor Entity will be required to register as an Investment
                 Company;

                            (C)     following such merger, consolidation,
                 amalgamation or replacement, the Trust (or the Successor
                 Entity) will continue to be classified as a grantor trust for
                 United States federal income tax purposes; and

                 (viii) the Sponsor guarantees the obligations of such
         Successor Entity under the Successor Securities at least to the extent
         provided by the Preferred Securities Guarantees.

                 (c)        Notwithstanding Section 3.15(b), the Trust shall
not, except with the consent of Holders of 100% in liquidation amount of the
Securities, consolidate, amalgamate, merge with or into, or be replaced by any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger or
replacement would cause the Trust or Successor Entity to be classified as other
than a grantor trust for United States federal income tax purposes.

                 to the Trust, the Sponsor and the resigning Institutional
                 Trustee; or

                            (B)     until the assets of the Trust have been

Delaware Trustee, as applicable, may petition any court of competent
jurisdiction for appointment of a Successor Institutional Trustee or Successor
Delaware Trustee.  Such court may thereupon, after prescribing such notice, if
any, as it may deem proper and prescribe, appoint a Successor Institutional
Trustee or Successor Delaware Trustee, as the case may be.

SECTION 5.8      Vacancies among Trustees.

                 If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 5.1, or if the number of
Trustees is increased pursuant to Section 5.1, a vacancy shall occur.  A
resolution certifying the existence of such vacancy by the Regular Trustees or,
if there are more than two, a majority of the Regular Trustees shall be
conclusive evidence of the existence of such vacancy.  The vacancy shall be
filled with a Trustee appointed in accordance with Section 5.7.

of Regular Trustees shall occur, until such vacancy is filled by the
appointment of a Regular Trustee in accordance with Section 5.7, the Regular
Trustees in office, regardless of their number, shall have all the powers
granted to the Regular Trustees and shall discharge all the duties imposed upon
the Regular Trustees by this Declaration.

place fixed by resolution of the Regular Trustees.  Notice of any in-person

the Regular Trustees or any committee





                                       32
<PAGE>   38
thereof shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours before
a meeting.  Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting.  The presence (whether in person or by
telephone) of a Regular Trustee at a meeting shall constitute a waiver of
notice of such meeting except where a Regular Trustee attends a meeting for the
express purpose of objecting to the transaction of any activity on the ground
that the meeting has not been lawfully called or convened.  Unless provided
otherwise in this Declaration, any action of the Regular Trustees may be taken
at a meeting by vote of a majority of the Regular Trustees present (whether in
person or by telephone) and eligible to vote with respect to such matter,
provided that a Quorum is present, or without a meeting by the unanimous
written consent of the Regular Trustees.  In the event there is only one
Regular Trustee, any and all action of such Regular Trustee shall be evidenced
by a written consent of such Regular Trustee.

SECTION 5.11     Delegation of Power.

                 (a)        Any Regular Trustee may, by power of attorney
consistent with applicable law, delegate to any other natural person over the

contemplated in Section 3.6, including any registration statement or amendment
thereto filed with the Commission, or making any other governmental filing; and

                 (b)        the Regular Trustees shall have power to delegate
from time to time to such of their number or to officers of the Trust the doing
of such things and the execution of such instruments either in the name of the
Trust or the names of the Regular Trustees or otherwise as the Regular Trustees
may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

Section 5.12     Merger, Conversion, Consolidation or Succession to Business.

         Any corporation into which the Institutional Trustee or the Delaware
Trustee, as the case may be, may be merged or converted or with which either
may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Institutional Trustee or the Delaware Trustee, as
the case may be, shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Institutional Trustee or
the Delaware Trustee, as the case may be, shall be the successor of the
Institutional Trustee or the Delaware Trustee, as the case may be, hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article,





                                       33

                                 DISTRIBUTIONS

SECTION 6.1      Distributions.

                 Holders shall receive Distributions (as defined herein) in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Preferred Securities and the Common
Securities in accordance with the preferences set forth in their respective
terms.  If and to the extent that the Debenture Issuer makes a payment of
interest (including Compounded Interest (as defined in the Indenture) and
Additional Interest (as defined in the Indenture)), premium and/or principal on
the Debentures held by the Institutional Trustee (the amount of any such
payment being a "Payment Amount"), the Institutional Trustee shall and is
directed, to the extent funds are available for that purpose, to make a
distribution (a "Distribution") of the Payment Amount to Holders.


                                  ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1      General Provisions Regarding Securities.

                 (a)        The Regular Trustees shall on behalf of the Trust
issue one class of preferred securities representing undivided beneficial
interests in the assets of the Trust having such terms as are set forth in
Annex I (the "Preferred Securities") and one class of common securities
representing undivided beneficial interests in the assets of the Trust having
such terms as are set forth in Annex I (the "Common Securities.")  The Trust
shall issue no securities or other interests in the assets of the Trust other
than the Preferred Securities and the Common Securities.

                 (b)        The Certificates shall be signed on behalf of the
Trust by a Regular Trustee.  Such signature shall be the manual signature of
any present or any future Regular Trustee.  In case any Regular Trustee of the
Trust who shall have signed any of the Securities shall cease to be such
Regular Trustee before the Certificates so signed shall be delivered by the
Trust, such Certificates nevertheless may be delivered as though the person who
signed such Certificates had not ceased to be such Regular Trustee; and any
Certificate may be signed on behalf of the Trust by such persons who, at the
actual date of execution of such Security, shall be the Regular Trustees of the
Trust, although at the date of the execution and delivery of the Declara-





                                       34
<PAGE>   40
tion any such person was not such a Regular Trustee.  Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Regular Trustees, as evidenced by their execution
thereof, and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements as the Regular Trustees may deem
appropriate, or as may be required to comply with any law or with any rule or
regulation of any stock exchange on which Securities may be listed, or to
conform to usage.

                 (c)        The consideration received by the Trust for the
issuance of the Securities shall constitute a contribution to the capital of
the Trust and shall not constitute a loan to the Trust.

                 (d)        Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable.

                 (e)        Every Person, by virtue of having become a Holder
or a Preferred Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration.

SECTION 7.2      Paying Agent.

                 In the event that the Preferred Securities are not in
book-entry only form, the Trust shall maintain in the Borough of Manhattan,
City of New York, State of New York, an office or agency where the Preferred
Securities may be presented for payment ("Paying Agent).  The Trust may appoint
the Paying Agent and may appoint one or more additional paying agents in such
other locations as it shall determine.  The term "Paying Agent" includes any
additional paying agent.  The Trust may change any Paying Agent without prior
notice to any Holder.  The Trust shall notify the Institutional Trustee of the
name and address of any Agent not a party to this Declaration.  If the Trust
fails to appoint or maintain another entity as Paying Agent, the Institutional
Trustee shall act as such.  The Trust or any of its Affiliates may act as
Paying Agent.  The Trust shall initially act as Paying Agent for the Preferred
Securities and the Common Securities.

         Securities in exchange for all of the Securities; or

         consent of all of the Regular Trustees and the Sponsor.

                 (b)        As soon as is practicable after the occurrence of
an event referred to in Section 8.1(a), the Trustees shall file a certificate
of cancellation with the Secretary of State of the State of Delaware.

                 (c)        The provisions of Section 3.9 and Article X shall
survive the termination of the Trust.

charge but only upon payment (with such indemnity as the Regular Trustees may
require) in respect of any tax or other government charges that may be imposed
in relation to it.  Upon surrender for registration of transfer of any
Certificate, the Regular Trustees shall cause one or more new Certificates to
be issued in the name of the designated transferee or transferees.  Every
Certificate surrendered for registration of transfer shall be accompanied by a
written instrument of transfer in form satisfactory to the Regular Trustees
duly executed by the Holder or such Holder's attorney duly authorized in
writing.  Each Certificate surrendered for registration of transfer shall be
canceled by the Regular Trustees.  A transferee of a Certificate shall be
entitled to the rights and subject to the obligations of a Holder hereunder

Certificate, each transferee shall be deemed to have agreed to be bound by this
Declaration.

have actual or other notice thereof.

Trust in the name of Cede & Co., the nominee of DTC, and no Preferred Security
Beneficial Owner will receive a definitive

<PAGE>   43
Preferred Security Certificate representing such Preferred Security Beneficial
Owner's interests in such Global Certifi- cates, except as provided in Section
9.7.  Unless and until definitive, fully registered Preferred Security

                 (a)        the provisions of this Section 9.4 shall be in full
         force and effect;

                 (b)        the Trust and the Trustees shall be entitled to
         deal with the Clearing Agency for all purposes of this Declaration
         (including the payment of Distributions on the Global Certificates and
         receiving approvals, votes or consents hereunder) as the Holder of the
         Preferred Securities and the sole holder of the Global Certificates
         and shall have no obligation to the Preferred Security Beneficial
         Owners;

                 (c)        to the extent that the provisions of this Section
         9.4 conflict with any other provisions of this Declaration, the
         provisions of this Section 9.4 shall control; and

                 (d)        the rights of the Preferred Security Beneficial
         Owners shall be exercised only through the Clearing Agency and shall
         be limited to those established by law and agreements between such
         Preferred Security Beneficial Owners and the Clearing Agency and/or
         the Clearing Agency Participants and receive and transmit payments of
         Distributions on the Global Certificates to such Clearing Agency
         Participants.  DTC will make book entry transfers among the Clearing
         Agency Participants.

SECTION 9.5      Notices to Clearing Agency.

                 Whenever a notice or other communication to the Preferred
Security Holders is required under this Declaration, unless and until
Definitive Preferred Security Certificates shall have been issued to the
Preferred Security Beneficial Owners pursuant to Section 9.7, the Regular

         services as securities depositary with respect to the Preferred
         Securities and a successor Clearing Agency is not appointed within 90
         days after such discontinuance pursuant to Section 9.6; or

                 (b)        the Regular Trustees elect after consultation with
         the Sponsor to terminate the book entry system through the Clearing
         Agency with respect to the Preferred Securities,

         prepared by the Regular Trustees on behalf of the Trust with respect
         to such Preferred Securities; and

                 (d)        upon surrender of the Global Certificates by the
         Clearing Agency, accompanied by registration instructions, the Regular
         Trustees shall cause Definitive Certificates to be delivered to
         Preferred Security Beneficial Owners in accordance with the
         instructions of the Clearing Agency.  Neither the Trustees nor the
         Trust shall be liable for any delay in delivery of such instructions
         and each of them may conclusively rely on and shall be protected in
         relying on, said instructions of the Clearing Agency.  The Definitive
         Preferred Security Certificates shall be printed, lithographed or
         engraved or may be produced in any other manner as is reasonably
         acceptable to the Regular Trustees, as evidenced by their execution
         thereof, and may have such letters, numbers or other marks of
         identification or designation and such legends or endorsements as the
         Regular Trustees may deem appropriate, or as may be required to comply
         with any law or with any rule or regulation made pursuant thereto or
         with any rule or regulation of any stock exchange on which Preferred
         Securities may be listed, or to conform to usage.

SECTION 9.8      Mutilated, Destroyed, Lost or Stolen Certificates.

                 If:

                 (a)        any mutilated Certificates should be surrendered to
         the Regular Trustees, or if the Regular Trustees shall receive
         evidence to their satisfaction of the destruction, loss or theft of
         any Certificate; and





                                       39
<PAGE>   45
                 (b)        there shall be delivered to the Regular Trustees
         such security or indemnity as may be required by them to keep each of
         them harmless.

then, in the absence of notice that such Certificate shall have been acquired
by a bona fide purchaser, any Regular Trustee on behalf of the Trust shall
execute and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate of like denomination.
In connection with the issuance of any new Certificate under this Section 9.8,
the Regular Trustees 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 Certificate issued pursuant to this Section shall constitute
conclusive evidence of an ownership interest in the relevant Securities, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

                   HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1     Liability.

                 (a)        Except as expressly set forth in this Declaration,
the Securities Guarantees and the terms of the Securities, the Sponsor shall
not be:

                 (i)        personally liable for the return of any portion of
         the capital contributions (or any return thereon) of the Holders of
         the Securities which shall be made solely from assets of the Trust;
         and

                 (ii)       be required to pay to the Trust or to any Holder of
         Securities any deficit upon dissolution of the Trust or otherwise.

                 (b)        The Holder of the Common Securities shall be liable
for all of the debts and obligations of the Trust (other than with respect to
the Securities) to the extent not satisfied out of the Trust's assets.

                 (c)        Pursuant to Section  3803(a) of the Business Trust
Act, the Holders of the Preferred Securities 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.

SECTION 10.2     Exculpation.





                                       40
<PAGE>   46
                 (a)        No Indemnified Person shall be liable, responsible
or accountable in damages or otherwise to the Trust or any Covered Person for
any loss, damage or claim incurred by reason of 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 the authority conferred on such Indemnified Person by this Declaration or by
law, except that an Indemnified Person shall be liable for any such loss,
damage or claim incurred by reason of such Indemnified Person's gross
negligence or willful misconduct with respect to such acts or omissions.

                 (b)        An Indemnified Person shall be fully protected in
relying in good faith upon the records of the Trust and upon such information,
opinions, reports or statements presented to the Trust by any Person as to
matters the Indemnified Person reasonably believes are within such other
Person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any other facts pertinent to the existence and amount of
assets from which Distributions to Holders of Securities might properly be
paid.

SECTION 10.3     Fiduciary Duty.

                 (a)        To the extent that, at law or in equity, an
Indemnified Person has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to any other Covered Person, an Indemnified
Person acting under this Declaration shall not be liable to the Trust or to any
other Covered Person for its good faith reliance on the provisions of this
Declaration.  The provisions of this Declaration, to the extent that they
restrict the duties and liabilities of an Indemnified Person otherwise existing
at law or in equity (other than the duties imposed on the Institutional Trustee
under the Trust Indenture Act), are agreed by the parties hereto to replace
such other duties and liabilities of such Indemnified Person.

                 (b)        Unless otherwise expressly provided herein:

                 (i)        whenever a conflict of interest exists or arises
         between any Covered Persons; or

                 (ii)       whenever this Declaration or any other agreement
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such
action or provide such terms, considering in each case





                                       41
<PAGE>   47
the relative interest of each party (including its own interest) to such
conflict, agreement, transaction or situation and the benefits and burdens
relating to such interests, any customary or accepted industry practices, and
any applicable generally accepted accounting practices or principles.  In the
absence of bad faith by the Indemnified Person, the resolution, action or term
so made, taken or provided by the Indemnified Person shall not constitute a
breach of this Declaration or any other agreement contemplated herein or of any
duty or obligation of the Indemnified Person at law or in equity or otherwise.

                 (c)        Whenever in this Declaration an Indemnified Person
is permitted or required to make a decision:

                 (i)        in its "discretion" or under a grant of similar
         authority, the Indemnified Person shall be entitled to consider such
         interests and factors as it desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

                 (ii)       in its "good faith" or under another express
         standard, the Indemnified Person shall act under such express standard
         and shall not be subject to any other or different standard imposed by
         this Declaration or by applicable law.

SECTION 10.4     Indemnification.

                 (a) (i)   The Debenture Issuer shall indemnify, to the full
extent permitted by law, any Company Indemnified Person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Trust) by reason
of the fact that he is or was a Company Indemnified Person against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Trust, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful.  The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the Company
Indemnified Person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the Trust,
and, with respect to any criminal action or proceeding, had reasonable cause to
believe that his conduct was unlawful.





                                       42
<PAGE>   48
                 (ii)       The Debenture Issuer shall indemnify, to the full
         extent permitted by law, any Company Indemnified Person who was or is
         a party or is threatened to be made a party to any threatened, pending
         or completed action or suit by or in the right of the Trust to procure
         a judgment in its favor by reason of the fact that he is or was a
         Company Indemnified Person against expenses (including attorneys'
         fees) actually and reasonably incurred by him in connection with the
         defense or settlement of such action or suit if he acted in good faith
         and in a manner he reasonably believed to be in or not opposed to the
         best interests of the Trust and except that no such indemnification
         shall be made in respect of any claim, issue or matter as to which
         such Company Indemnified Person shall have been adjudged to be liable
         to the Trust unless and only to the extent that the Court of Chancery
         of Delaware or the court in which such action or suit was brought
         shall determine upon application that, despite the adjudication of
         liability but in view of all the circumstances of the case, such
         person is fairly and reasonably entitled to indemnity for such
         expenses which such Court of Chancery or such other court shall deem
         proper.

                 (iii)      To the extent that a Company Indemnified Person
         shall be successful on the merits or otherwise (including dismissal of
         an action without prejudice or the settlement of an action without
         admission of liability) in defense of any action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 10.4(a), or in
         defense of any claim, issue or matter therein, he shall be
         indemnified, to the full extent permitted by law, against expenses
         (including attorneys' fees) actually and reasonably incurred by him in
         connection therewith.

                 (iv)       Any indemnification under paragraphs (i) and (ii)
         of this Section 10.4(a) (unless ordered by a court) shall be made by
         the Debenture Issuer only as authorized in the specific case upon a
         determination that indemnification of the Company Indemnified Person
         is proper in the circumstances because he has met the applicable
         standard of conduct set forth in paragraphs (i) and (ii).  Such
         determination shall be made (1) by the Regular Trustees by a majority
         vote of a quorum consisting of such Regular Trustees who were not
         parties to such action, suit or proceeding, (2) if such a quorum is
         not obtainable, or, even if obtainable, if a quorum of disinterested
         Regular Trustees so directs, by independent legal counsel in a written
         opinion, or (3) by the Common Security Holder of the Trust.

                 (v)        Expenses (including attorneys' fees) incurred by a
         Company Indemnified Person in defending a civil, criminal,
         administrative or investigative action, suit or proceeding referred to
         in paragraphs (i) and (ii) of this Section





                                       43
<PAGE>   49
         10.4(a) shall be paid by the Debenture Issuer in advance of the final
         disposition of such action, suit or proceeding upon receipt of an
         undertaking by or on behalf of such Company Indemnified Person to
         repay such amount if it shall ultimately be determined that he is not
         entitled to be indemnified by the Debenture Issuer as authorized in
         this Section 10.4(a).  Notwithstanding the foregoing, no advance shall
         be made by the Debenture Issuer if a determination is reasonably and
         promptly made (i) by the Regular Trustees by a majority vote of a
         quorum of disinterested Regular Trustees, (ii) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Regular Trustees so directs, by independent legal counsel in a written
         opinion or (iii) the Common Security Holder of the Trust, that, based
         upon the facts known to the Regular Trustees, counsel or the Common
         Security Holder at the time such determination is made, such Company
         Indemnified Person acted in bad faith or in a manner that such person
         did not believe to be in or not opposed to the best interests of the
         Trust, or, with respect to any criminal proceeding, that such Company
         Indemnified Person believed or had reasonable cause to believe his
         conduct was unlawful.  In no event shall any advance be made in
         instances where the Regular Trustees, independent legal counsel or
         Common Security Holder reasonably determine that such person
         deliberately breached his duty to the Trust or its Common or Preferred
         Security Holders.

                 (vi)       The indemnification and advancement of expenses
         provided by, or granted pursuant to, the other paragraphs of this
         Section 10.4(a) shall not be deemed exclusive of any other rights to
         which those seeking indemnification and advancement of expenses may be
         entitled under any agreement, vote of stockholders or disinterested
         directors of the Debenture Issuer or Preferred Security Holders of the
         Trust or otherwise, both as to action in his official capacity and as
         to action in another capacity while holding such office.  All rights
         to indemnification under this Section 10.4(a) shall be deemed to be
         provided by a contract between the Debenture Issuer and each Company
         Indemnified Person who serves in such capacity at any time while this
         Section 10.4(a) is in effect.  Any repeal or modification of this
         Section 10.4(a) shall not affect any rights or obligations then
         existing.

                 (vii)      The Debenture Issuer or the Trust may purchase and
         maintain insurance on behalf of any person who is or was a Company
         Indemnified Person against any liability asserted against him and
         incurred by him in any such capacity, or arising out of his status as
         such, whether or not the Debenture Issuer would have the power to
         indemnify him against such liability under the provisions of this
         Section 10.4(a).

<PAGE>   50
                 (viii)     For purposes of this Section 10.4(a), references to
         "the Trust" shall include, in addition to the resulting or surviving
         entity, any constituent entity (including any constituent of a
         constituent) absorbed in a consolidation or merger, so that any person
         who is or was a director, trustee, officer or employee of such
         constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee or agent
         of another entity, shall stand in the same position under the
         provisions of this Section 10.4(a) with respect to the resulting or
         surviving entity as he would have with respect to such constituent
         entity if its separate existence had continued.

                 (ix)       The indemnification and advancement of expenses
         provided by, or granted pursuant to, this Section 10.4(a) shall,
         unless otherwise provided when authorized or ratified, continue as to
         a person who has ceased to be a Company Indemnified Person and shall
         inure to the benefit of the heirs, executors and administrators of
         such a person.

                 (b)        The Debenture Issuer agrees to indemnify the (i)
Institutional Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the
Institutional Trustee and the Delaware Trustee, and (iv) any officers,
directors, shareholders, members, partners, employees, representatives,
custodians, nominees or agents of the Institutional Trustee and the Delaware
Trustee (each of the Persons in (i) through (iv) being referred to as a
"Fiduciary Indemnified Person") for, and to hold each Fiduciary Indemnified
Person harmless against, any loss, liability or expense incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration or the trust or trusts hereunder, including the
costs and expenses (including reasonable legal fees and expenses) of defending
itself against or investigating any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder.  The
obligation to indemnify as set forth in this Section 10.4(b) shall survive the
satisfaction and discharge of this Declaration.

SECTION 10.5     Outside Businesses.

                 Any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional Trustee may 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
Securities shall have no rights by virtue of this Declaration 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.  No Covered Person, the
Sponsor, the Delaware Trustee, or the Institutional Trustee shall be obligated
to pres-





                                       45
<PAGE>   51
ent any particular investment or other opportunity to the Trust even if such
opportunity is of a character that, if pre- sented to the Trust, could be taken
by the Trust, and any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional 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 Covered Person, the Delaware
Trustee and the Institutional Trustee may engage or be interested in any
financial or other transaction with the Sponsor or any Affiliate of the
Sponsor, or may act as depositary for, trustee or agent for, or act on any
committee or body of holders of, securities or other obligations of the Sponsor
or its Affiliates.

                                   ACCOUNTING

SECTION 11.1     Fiscal Year.

                 The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

SECTION 11.2     Certain Accounting Matters.

                 (a)        At all times during the existence of the Trust, the
Regular Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail,
each transaction of the Trust.  The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied.  The Trust shall use the accrual method of
accounting for United States federal income tax purposes.  The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year of the Trust by a firm of independent certified public
accountants selected by the Regular Trustees.

                 (b)        The Regular Trustees shall cause to be prepared and
delivered to each of the Holders of Securities, within 90 days after the end of
each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss;

                 (c)        The Regular Trustees shall cause to be duly
prepared and delivered to each of the Holders of Securities, any annual United
States federal income tax information statement, required by the Code,
containing such information with regard to the Securities held by each Holder
as is required by the Code and the Treasury Regulations.  Notwithstanding any
right under the Code to deliver any such statement at a later date, the Regular





                                       46
<PAGE>   52
Trustees shall endeavor to deliver all such statements within 30 days after the
end of each Fiscal Year of the Trust.

                 (d)        The Regular Trustees shall cause to be duly
prepared and filed with the appropriate taxing authority, an annual United
States federal income tax return, on a Form 1041 or such other form required by
United States federal income tax law, and any other annual income tax returns
required to be filed by the Regular Trustees on behalf of the Trust with any
state or local taxing authority.

SECTION 11.3     Banking.

                 The Trust shall maintain one or more bank accounts in the name
and for the sole benefit of the Trust; provided, however, that all payments of
funds in respect of the Debentures held by the Institutional Trustee shall be
made directly to the Institutional Trustee Account and no other funds of the
Trust shall be deposited in the Institutional Trustee Account.  The sole
signatories for such accounts shall be designated by the Regular Trustees;
provided, however, that the Institutional Trustee shall designate the
signatories for the Institutional Trustee Account.

SECTION 11.4     Withholding.

                 The Trust and the Regular Trustees shall comply with all
withholding requirements under United States federal, state and local law.  The
Trust shall request, and the Holders shall provide to the Trust, such forms or
certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably
be requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations.  The Regular Trustees shall file
required forms with applicable jurisdictions and, unless an exemption from
withholding is properly established by a Holder, shall remit amounts withheld
with respect to the Holder to applicable jurisdictions.  To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to distributions or allocations to any Holder, the amount withheld
shall be deemed to be a distribution in the amount of the withholding to the
Holder.  In the event of any claimed over withholding, Holders shall be limited
to an action against the applicable jurisdiction.  If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

                            AMENDMENTS AND MEETINGS

SECTION 12.1     Amendments.

                 (a)        Except as otherwise provided in this Declaration or
by any applicable terms of the Securities, this Declaration may only be amended
by a written instrument approved and executed by:

                 (i)        the Regular Trustees (or, if there are more than
         two Regular Trustees a majority of the Regular Trustees);

                 (ii)       if the amendment affects the rights, powers,
         duties, obligations or immunities of the Institutional Trustee, the
         Institutional Trustee; and

                 (iii)      if the amendment affects the rights, powers,
         duties, obligations or immunities of the Delaware Trustee, the
         Delaware Trustee;

                 (b)        no amendment shall be made, and any such purported
amendment shall be void and ineffective:

                 (i)        unless, in the case of any proposed amendment, the
         Institutional Trustee shall have first received an Officers'
         Certificate from each of the Trust and the Sponsor that such amendment
         is permitted by, and conforms to, the terms of this Declaration
         (including the terms of the Securities);

                 (ii)       unless, in the case of any proposed amendment which
         affects the rights, powers, duties, obligations or immunities of the

SECTION 12.2     Meetings of the Holders of Securities; Action by Written
                 Consent.

                 (a)        Meetings of the Holders of any class of Securities
may be called at any time by the Regular Trustees (or as provided in the terms
of the Securities) to consider and act on any matter on which Holders of such
class of Securities are entitled to act under the terms of this Declaration,
the terms of the Securities or the rules of any stock exchange on which the
Preferred Securities are listed or admitted for trading.  The Regular Trustees
shall call a meeting of the Holders of such class if directed to do so by the
Holders of at least 10% in liquidation amount of such class of Securities.
Such direction shall be given by delivering to the Regular Trustees one or more
calls in a writing stating that the signing Holders of Securities wish to call
a meeting and indicating the general or specific purpose for which the meeting
is to be called.  Any Holders of Securities calling a meeting shall specify in
writing the Security Certificates held by the Holders of Securities exercising
the right to call a meeting and only those Securities specified shall be
counted for purposes of determining whether the required percentage set forth
in the second sentence of this paragraph has been met.

                 (b)        Except to the extent otherwise provided in the
terms of the Securities, the following provisions shall apply to meetings of
Holders of Securities:

                 (i)        notice of any such meeting shall be given to all
         the Holders of Securities having a right to vote thereat at least 7
         days and not more than 60 days before the date of such meeting.
         Whenever a vote, consent or approval of the Holders of Securities is
         permitted or required under this Declaration or the rules of any stock
         exchange on which the Preferred Securities are listed or admitted for
         trading, such vote, consent or approval may be given at a meeting of
         the Holders of Securities.  Any action that may be taken at a meeting
         of the Holders of Securities may be taken without a meeting if a
         consent in writing setting forth the action so taken is signed by the
         Holders of Securities owning not less than the minimum amount of
         Securities in liquidation amount that would be necessary to authorize
         or take such action at a meeting at which all Holders of Securities
         having a right to vote thereon were present and voting.  Prompt notice
         of the taking of action without a meeting shall be given to the
         Holders of Securities entitled to vote who have not consented in
         writing.  The Regular Trustees may specify that any written ballot
         submitted to the Security Holder for the purpose of taking any action
         without a meeting shall be returned to the Trust within the time
         specified by the Regular Trustees;

                 (ii)       each Holder of a Security may authorize any Person
         to act for it by proxy on all matters in which a Holder of Securities
         is entitled to participate, including waiving notice of any meeting,
         or voting or participating at a meeting.  No proxy shall be valid
         after the expiration of 11 months from the date thereof unless
         otherwise provided in the proxy.  Every proxy shall be revocable at
         the pleasure of the Holder of Securities executing it.  Except as
         otherwise provided herein, all matters relating to the giving, voting
         or validity of proxies shall be governed by the General Corporation
         Law of the State of Delaware relating to proxies, and judicial
         interpretations thereunder, as if the Trust were a Delaware
         corporation and the Holders of the Securities were stockholders of a
         Delaware corporation;

                 (iii)      each meeting of the Holders of the Securities shall
         be conducted by the Regular Trustees or by such other Person that the
         Regular Trustees may designate; and

                 (iv)       unless the Business Trust Act, this Declaration,
         the terms of the Securities, the Trust Indenture Act or the listing
         rules of any stock exchange on which the Preferred Securities are then
         listed or trading, otherwise provides, the Regular Trustees, in their
         sole discretion, shall establish all other provisions relating to
         meetings of Holders of Securities, including notice of the time, place
         or purpose of any meeting at which any matter is to be voted on by any
         Holders of Securities, waiver of any such notice, action by consent
         without a meeting, the establishment of a record date, quorum
         requirements, voting in person or by proxy or any other matter with
         respect to the exercise of any such right to vote.

                                    TERMS OF
                   ___% TRUST ORIGINATED PREFERRED SECURITIES
                    ___% TRUST ORIGINATED COMMON SECURITIES


                 Pursuant to Section 7.1 of the Amended and Restated
Declaration of Trust, dated as of _______, 1996 (as amended from time to time,
the "Declaration"), the designation, rights, privileges, restrictions,
preferences and other terms and provisions of the Preferred Securities and the
Common Securities are set out below (each capitalized term used but not defined
herein has the meaning set forth in the Declaration or, if not defined in such
Declaration, as defined in the Prospectus referred to below):

                 1.       Designation and Number.

                 (a)      Preferred Securities.  [                ] Preferred
Securities of the Trust with an aggregate liquidation amount with respect to
the assets of the Trust of [             ] dollars ($[            ]) and a
liquidation amount with respect to the assets of the Trust of $25 per preferred
security, are hereby designated for the purposes of identification only as
"_____% Trust Originated Preferred SecuritiesSM ('TOPrS'SM)" (the "Preferred
Securities").  The Preferred Security Certificates evidencing the Preferred
Securities shall be substantially in the form of Exhibit A-1 to the
Declaration, with such changes and additions thereto or deletions therefrom as
may be required by ordinary usage, custom or practice or to conform to the
rules of any stock exchange on which the Preferred Securities are listed.

                 (b)      Common Securities.  [               ] Common
Securities of the Trust with an aggregate liquidation amount with respect to
the assets of the Trust of [               ] dollars ($[           ]) and a
liquidation amount with respect to the assets of the Trust of $25 per common
security, are hereby designated for the purposes of identification only as
"______% Trust Originated Common Securities" (the "Common Securities").  The
Common Security Certificates evidencing the Common Securities shall be
substantially in the form of Exhibit A-2 to the Declara- tion, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice.

                 2.       Distributions.

                 (a)      Distributions payable on each Security will be fixed
at a rate per annum of ______% (the "Coupon Rate") of the stated liquidation
amount of $25 per Security, such rate being





                                      I-1
<PAGE>   63
the rate of interest payable on the Debentures to be held by the Institutional
Trustee.  Distributions in arrears for more than one quarter will bear interest
thereon compounded quarterly at the Coupon Rate (to the extent permitted by
applicable law).  The term "Distributions" as used herein includes such cash
distributions and any such interest payable unless otherwise stated.  A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Institutional Trustee and to the extent the
Institutional Trustee has funds available therefor.  The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 90-day quarter.

                 (b)      Distributions on the Securities will be cumulative,
will accrue from ________, 1996, and will be payable quarterly in arrears, on
[March 31, June 30, September 30, and December 31] of each year, commencing on
_______, 1996, except as otherwise described below.  The Debenture Issuer has
the right under the Indenture to defer payments of interest by extending the
interest payment period from time to time on the Debentures for a period not
exceeding 20 consecutive quarters or extend beyond the maturity date of the
Debentures (each an "Extension Period"), during which Extension Period no
interest shall be due and payable on the Debentures, provided that no Extension
Period shall last beyond the date of maturity of the Debentures.  As a
consequence of such deferral, Distributions will also be deferred.  Despite
such deferral, quarterly Distributions will continue to accrue with interest
thereon (to the extent permitted by applicable law) at the Coupon Rate
compounded quarterly during any such Extension Period.  Prior to the
termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters or extend beyond the maturity of the Debentures.  Payments of accrued
Distributions will be payable to Holders as they appear on the books and
records of the Trust on the first record date after the end of the Extension
Period.  Upon the termination of any Extension Period and the payment of all
amounts then due, the Debenture Issuer may commence a new Extension Period,
subject to the above requirements.

                 (c)      Distributions on the Securities will be payable to
the Holders thereof as they appear on the books and records of the Trust on the
relevant record dates.  While the Preferred Securities remain in book-entry
only form, the relevant record dates shall be one Business Day prior to the
relevant payment dates which payment dates correspond to the interest payment
dates on the Debentures.  Subject to any applicable laws and





                                      I-2
<PAGE>   64
regulations and the provisions of the Declaration, each such payment in respect
of the Preferred Securities will be made as described under the heading
"Description of the Preferred Securities -- Book-Entry Only Issuance -- The
Depository Trust Company" in the Prospectus Supplement dated______, 1996, to
the Prospectus dated ______, 1996 (together, the "Prospectus"), of the Trust
included in the Registration Statement on Form S-3 of the Sponsor, the Trust
and certain other business trusts.  The relevant record dates for the Common
Securities shall be the same record date as for the Preferred Securities.  If
the Preferred Securities shall not continue to remain in book-entry only form,
the relevant record dates for the Preferred Securities, shall conform to the
rules of any securities exchange on which the securities are listed and, if
none, shall be selected by the Regular Trustees, which dates shall be at least
one Business Day but less than 60 Business Days before the relevant payment
dates, which payment dates correspond to the interest payment dates on the
Debentures.  Distributions payable on any Securities that are not punctually
paid on any Distribution payment date, as a result of the Debenture Issuer
having failed to make a payment under the Debentures, will cease to be payable
to the Person in whose name such Securities are registered on the relevant
record date, and such defaulted Distribution will instead be payable to the
Person in whose name such Securities are registered on the special record date
or other specified date determined in accordance with the Indenture.  If any
date on which Distributions are payable on the Securities is not a Business
Day, then payment of the Distribution 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 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 such date.

                 (d)      In the event that there is any money or other
property held by or for the Trust that is not accounted for hereunder, such
property shall be distributed Pro Rata (as defined herein) among the Holders of
the Securities.

                 3.       Liquidation Distribution Upon Dissolution.

                 In the event of any voluntary or involuntary dissolution,
winding-up or termination of the Trust, the Holders of the Securities on the
date of the dissolution, winding-up or termination, as the case may be, will be
entitled to receive out of the assets of the Trust available for distribution
to Holders of Securities after satisfaction of liabilities of creditors an
amount equal to the aggregate of the stated liquidation amount of $25 per
Security plus accrued and unpaid Distributions thereon to the date of payment
(such amount being the "Liquidation Distribution"), unless, in connection with
such dissolution, winding-up or termination, Debentures in an aggregate stated
principal





                                      I-3
<PAGE>   65
amount equal to the aggregate stated liquidation amount of such Securities,
with an interest rate equal to the Coupon Rate of, and bearing accrued and
unpaid interest in an amount equal to the accrued and unpaid Distributions on,
such Securities, shall be distributed on a Pro Rata basis to the Holders of the
Securities in exchange for such Securities.

                 If, upon any such dissolution, 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 the Securities shall be paid on a Pro Rata basis.

                 4.       Redemption and Distribution.

                 (a)      Upon the repayment of the Debentures in whole or in
part, whether at maturity or upon redemption (either at the option of the
Debenture Issuer or pursuant to a Tax Event as described below), the proceeds
from such repayment or payment shall be simultaneously applied to redeem
Securities having an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so repaid or redeemed at a redemption price
of $25 per Security plus an amount equal to accrued and unpaid Distributions
thereon at the date of the redemption, payable in cash (the "Redemption
Price").  Holders will be given not less than 30 nor more than 60 days notice
of such redemption.

                 (b)      If fewer than all the outstanding Securities are to
be so redeemed, the Common Securities and the Preferred Securities will be
redeemed Pro Rata and the Preferred Securities to be redeemed will be as
described in Section 4(f)(ii) below.

                 (c)      If, at any time, a Tax Event (as defined below) shall
occur and be continuing the Regular Trustees shall, except in certain limited
circumstances described in this Section 4(c), dissolve the Trust and, after
satisfaction of creditors, cause Debentures held by the Institutional Trustee,
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the Coupon Rate of, and accrued
and unpaid interest equal to accrued and unpaid Distributions on, and having
the same record date for payment as the Securities, to be distributed to the
Holders of the Securities in liquidation of such Holders' interests in the
Trust on a Pro Rata basis, within 90 days following the occurrence of such Tax
Event (the "90 Day Period"); provided, however, that, as a condition of such
dissolution and distribution, the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "No Recognition Opinion"), which opinion may rely on published
revenue rulings of the Internal Revenue Service, to the effect that the Holders
of the Securities will not recognize any gain or loss for United States federal
income tax purposes as a result of the dissolution of the





                                      I-4
<PAGE>   66
Trust and the distribution of Debentures, and provided, further, that, if at
the time there is available to the Trust the opportunity to eliminate, within
the 90 Day Period, the Tax Event by taking some ministerial action, such as
filing a form or making an election, or pursuing some other similar reasonable
measure that has no adverse effect on the Trust, the Debenture Issuer, the
Sponsor or the Holders of the Securities ("Ministerial Action"), the Trust will
pursue such Ministerial Action in lieu of dissolution.

                 If in the event of a Tax Event, (i) after receipt of a Tax
Event Opinion (as defined hereinafter) by the Regular Trustees, the Debenture
Issuer has received an opinion (a "Redemption Tax Opinion") of a nationally
recognized independent tax counsel experienced in such matters that, as a
result of a Tax Event, there is more than an insubstantial risk that the
Debenture Issuer would be precluded from deducting the interest on the
Debentures for United States federal income tax purposes even after the
Debentures were distributed to the Holders of Securities in liquidation of such
Holders' interests in the Trust as described in this Section 4(c), or (ii) the
Regular Trustees shall have been informed by such tax counsel that a No
Recognition Opinion cannot be delivered to the Trust, the Debenture Issuer
shall have the right at any time, upon not less than 30 nor more than 60 days
notice, to redeem the Debentures in whole or in part for cash within 90 days
following the occurrence of such Tax Event, and, following such redemption,
Securities with an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so redeemed shall be redeemed by the Trust
at the Redemption Price on a Pro Rata basis; provided, however, that, if at the
time there is available to the Debenture Issuer or the Trust the opportunity to
eliminate, within such 90 day period, the Special Event by taking some
Ministerial Action, the Trust or the Debenture Issuer will pursue such
Ministerial Action in lieu of redemption.

                 "Tax Event" means that the Regular Trustees shall have
received an opinion of a nationally recognized independent tax counsel
experienced in such matters (a "Dissolution Tax Opinion") to the effect that on
or after the date of the Prospectus Supplement, as a result of (a) any
amendment to, clarification of 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 affecting
taxation, (b) any judicial decision, official adminis- trative pronouncement,
ruling, regulatory procedure, notice or announcement, including any notice or
announcement of intent to adopt such procedures or regulations (an
"Administrative Action") or (c) any amendment to, clarification of, or change
in the official position or the interpretation of such Administrative Action or
judicial decision that differs from the theretofore generally accepted
position, in each case, by any legislative





                                      I-5
<PAGE>   67
body, court, governmental authority or regulatory body, irrespective of the
manner in which such amendment, clarification or change is made known, which
amendment, clarification, or change is effective or such pronouncement or
decision is announced, in each case, on or after, the first date of issuance of
the Securities, there is more than an insubstantial risk that (i) the Trust is
or will be within 90 days of the date thereof, subject to United States federal
income tax with respect to interest accrued or received on the Debentures, (ii)
the Trust is, or will be within 90 days of the date thereof, subject to more
than a de minimis amount of taxes, duties or other governmental charges, or
(iii) interest payable by the Debenture Issuer to the Trust on the Debentures
is not, or within 90 days of the date thereof will not be, deductible, in whole
or in part, by the Debenture Issuer for United States federal income tax
purposes.

                 On and from the date fixed by the Regular Trustees for any
distribution of Debentures and dissolution of the Trust:  (i) the Securities
will no longer be deemed to be outstanding, (ii) The Depository Trust Company
(the "Depository") or its nominee (or any successor Clearing Agency or its
nominee), as the record Holder of the Preferred Securities, will receive a
registered global certificate or certificates representing the Debentures to be
delivered upon such distribution and any certificates representing Securities,
except for certificates representing Preferred Securities held by the
Depository or its nominee (or any successor Clearing Agency or its nominee),
will be deemed to represent beneficial interests in the Debentures having an
aggregate principal amount equal to the aggregate stated liquidation amount of,
with an interest rate identical to the Coupon Rate of, and accrued and unpaid
interest equal to accrued and unpaid Distributions on such Securities until
such certificates are presented to the Debenture Issuer or its agent for
transfer or reissue.

                 (d)      The Trust may not redeem fewer than all the
outstanding Securities unless all accrued and unpaid Distributions have been
paid on all Securities for all quarterly Distribution periods terminating on or
before the date of redemption.

                 (e)      If the Debentures are distributed to holders of the
Securities, pursuant to the terms of the Indenture, the Debenture Issuer will
use its best efforts to have the Debentures listed on the New York Stock
Exchange or on such other exchange as the Preferred Securities were listed
immediately prior to the distribution of the Debentures.

                 (f)      "Redemption or Distribution Procedures."

                 (i)      Notice of any redemption of, or notice of
         distribution of Debentures in exchange for the Securities (a
         "Redemption/Distribution Notice") will be given by the Trust by





                                      I-6
<PAGE>   68
         mail to each Holder of Securities to be redeemed or exchanged not
         fewer than 30 nor more than 60 days before the date fixed for
         redemption or exchange thereof which, in the case of a redemption,
         will be the date fixed for redemption of the Debentures.  For purposes
         of the calculation of the date of redemption or exchange and the dates
         on which notices are given pursuant to this Section 4(f)(i), a
         Redemption/ Distribution Notice shall be deemed to be given on the day
         such notice is first mailed by first-class mail, postage prepaid, to
         Holders of Securities.  Each Redemption/Distribution Notice shall be
         addressed to the Holders of Securities at the address of each such
         Holder appearing in the books and records of the Trust.  No defect in
         the Redemption/Distribution Notice or in the mailing of either thereof
         with respect to any Holder shall affect the validity of the redemption
         or exchange proceedings with respect to any other Holder.

                 (ii)     In the event that fewer than all the outstanding
         Securities are to be redeemed, the Securities to be redeemed shall be
         redeemed Pro Rata from each Holder of Preferred Securities, it being
         understood that, in respect of Preferred Securities registered in the
         name of and held of record by the Depository or its nominee (or any
         successor Clearing Agency or its nominee) or any nominee, the
         distribution of the proceeds of such redemption will be made to each
         Clearing Agency Participant (or Person on whose behalf such nominee
         holds such securities) in accordance with the procedures applied by
         such agency or nominee.

                 (iii)    If Securities are to be redeemed and the Trust gives
         a Redemption/Distribution Notice, which notice may only be issued if
         the Debentures are redeemed as set out in this Section 4 (which notice
         will be irrevocable), then (A) while the Preferred Securities are in
         book-entry only form, with respect to the Preferred Securities, by
         12:00 noon, New York City time, on the redemption date, provided that
         the Debenture Issuer has paid the Institutional Trustee a sufficient
         amount of cash in connection with the related redemption or maturity
         of the Debentures, the Institutional Trustee will deposit irrevocably
         with the Depository or its nominee (or successor Clearing Agency or
         its nominee) funds sufficient to pay the applicable Redemption Price
         with respect to the Preferred Securities and will give the Depository
         irrevocable instructions and authority to pay the Redemption Price to
         the Holders of the Preferred Securities, and (B) with respect to
         Preferred Securities issued in definitive form and Common Securities,
         provided that the Debenture Issuer has paid the Institutional Trustee
         a sufficient amount of cash in connection with the related redemption
         or maturity of the Debentures, the Institutional Trustee will pay the
         relevant Redemption Price to the Holders of





                                      I-7
<PAGE>   69
         such Securities by check mailed to the address of the relevant Holder
         appearing on the books and records of the Trust on the redemption
         date.  If a Redemption/Distribution Notice shall have been given and
         funds deposited as required, if applicable, then immediately prior to
         the close of business on the date of such deposit, or on the
         redemption date, as applicable, distributions will cease to accrue on
         the Securities so called for redemption and all rights of Holders of
         such Securities so called for redemption will cease, except the right
         of the Holders of such Securities to receive the Redemption Price, but
         without interest on such Redemption Price.  Neither the Regular
         Trustees nor the Trust shall be required to register or cause to be
         registered the transfer of any Securities that have been so called for
         redemption.  If any date fixed for redemption of Securities 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 fixed for redemption.  If payment of the Redemption Price in
         respect of any Securities is improperly withheld or refused and not
         paid either by the Institutional Trustee or by the Sponsor as
         guarantor pursuant to the relevant Securities Guarantee, Distributions
         on such Securities will continue to accrue from the original
         redemption date to the actual date of payment, in which case the
         actual payment date will be considered the date fixed for redemption
         for purposes of calculating the Redemption Price.

                 (iv)     Redemption/Distribution Notices shall be sent by the
         Regular Trustees on behalf of the Trust to (A) in respect of the
         Preferred Securities, the Depository or its nominee (or any successor
         Clearing Agency or its nominee) if the Global Certificates have been
         issued or, if Definitive Preferred Security Certificates have been
         issued, to the Holder thereof, and (B) in respect of the Common
         Securities to the Holder thereof.

                 (v)      Subject to the foregoing and applicable law
         (including, without limitation, United States federal securities
         laws), provided the acquiror is not the Holder of the Common
         Securities or the obligor under the Indenture, the Sponsor or any of
         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.

                 5.       Voting Rights - Preferred Securities.

                 (a)      Except as provided under Sections 5(b) and 7 and as
otherwise required by law and the Declaration, the Holders of the Preferred
Securities will have no voting rights.

                 (b)      Subject to the requirements set forth in this
paragraph, the Holders of a majority in aggregate liquidation amount of the
Preferred Securities, voting separately as a class may direct the time, method,
and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including the right to direct the
Institutional Trustee, as holder of the Debentures, to (i) exercise the
remedies available under the Indenture conducting any proceeding for any remedy
available to the Debenture Trustee, or exercising any trust or power conferred
on the Debenture Trustee with respect to the Debentures, (ii) waive any past
default and its consequences that is waivable under Section ___ of the
Indenture, or (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable, provided,
however, that, where a consent under the Indenture would require the consent or
act of the Holders of greater than a majority of the Holders in principal
amount of Debentures affected thereby, (a "Super Majority"), the Institutional
Trustee may only give such consent or take such action at the written direction
of the Holders of at least the proportion in liquidation amount of the
Preferred Securities which the relevant Super Majority represents of the
aggregate principal amount of the Debentures outstanding.  The Institutional
Trustee shall not revoke any action previously authorized or approved by a vote
of the Holders of the Preferred Securities.  Other than with respect to
directing the time, method and place of conducting any remedy available to the
Institutional Trustee or the Debenture Trustee as set forth above, the
Institutional Trustee shall not take any action in accordance with the
directions of the Holders of the Preferred Securities under this paragraph
unless the Institutional Trustee has obtained an opinion of tax counsel to the
effect that for the purposes of United States federal income tax the Trust will
not be classified as other than a grantor trust on account of such action.  If
a Declaration Event of Default has occurred and is continuing and such event is
attributable to the failure of the Debenture Issuer to pay interest or
principal on the Debentures on the date such interest or principal is otherwise
payable (or in the case of redemption, on the redemption date), then a holder
of Preferred Securities may directly institute a proceeding for enforcement of
payment to such Holder of the principal of or interest on the Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder (a "Direct Action") on or after the respective due
date specified in the Debentures.  In connection with such Direct Action, the
rights of





                                      I-9
<PAGE>   71
the holders of the Common Securities Holder will be subrogated to the rights of
such holder of Preferred Securities to the extent of any payment made by the
Issuer to such holder of Preferred Securities in such Direct Action.  Except as
provided in the preceding sentences, the Holders of Preferred Securities will
not be able to exercise directly any other remedy available to the holders of
the Debentures.

                 Any approval or direction of Holders of Preferred Securities
may be given at a separate meeting of Holders of Preferred Securities convened
for such purpose, at a meeting of all of the Holders of Securities in the Trust
or pursuant to written consent.  The Regular Trustees will cause a notice of
any meeting at which Holders of Preferred Securities are entitled to vote, or
of any matter upon which action by written consent of such Holders is to be
taken, to be mailed to each Holder of record of Preferred Securities.  Each
such notice will include a statement setting forth (i) the date of such meeting
or the date by which such action is to be taken, (ii) a description of any
resolution proposed for adoption at such meeting on which such Holders are
entitled to vote or of such matter upon which written consent is sought and
(iii) instructions for the delivery of proxies or consents.

                 No vote or consent of the Holders of the Preferred Securities
will be required for the Trust to redeem and cancel Preferred Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                 Notwithstanding that Holders of Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Preferred Securities that are owned by the Sponsor or any Affiliate of
the Sponsor shall not be entitled to vote or consent and shall, for purposes of
such vote or consent, be treated as if they were not outstanding.

                 6.       Voting Rights - Common Securities.

                 (a)      Except as provided under Sections 7(b), (c) and 8 as
otherwise required by law and the Declaration, the Holders of the Common
Securities will have no voting rights.

                 (b)      The Holders of the Common Securities are entitled, in
accordance with Article V of the Declaration, to vote to appoint, remove or
replace any Trustee or to increase or decrease the number of Trustees.

                 (c)      Subject to Section 2.6 of the Declaration and only
after the Event of Default with respect to the Preferred Securities has been
cured, waived, or otherwise eliminated and subject to the requirements of the
second to last sentence of this paragraph, the Holders of a Majority in
liquidation amount of the





                                      I-10
<PAGE>   72
Common Securities, voting separately as a class, may direct the time, method,
and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including (i) directing the time,
method, place of conducting any proceeding for any remedy available to the
Debenture Trustee, or exercising any trust or power conferred on the Debenture
Trustee with respect to the Debentures, (ii) waive any past default and its
consequences that is waivable under Section ____ of the Indenture, or (iii)
exercise any right to rescind or annul a declaration that the principal of all
the Debentures shall be due and payable, provided that, where a consent or
action under the Indenture would require the consent or act of the Holders of
greater than a majority in principal amount of Debentures affected thereby (a
"Super Majority"), the Institu- tional Trustee may only give such consent or
take such action at the written direction of the Holders of at least the
proportion in liquidation amount of the Common Securities which the relevant
Super Majority represents of the aggregate principal amount of the Debentures
outstanding.  Pursuant to this Section 6(c), the Institutional Trustee shall
not revoke any action previously authorized or approved by a vote of the
Holders of the Preferred Securities.  Other than with respect to directing the
time, method and place of conducting any remedy available to the Institutional
Trustee or the Debenture Trustee as set forth above, the Institutional Trustee
shall not take any action in accordance with the directions of the Holders of
the Common Securities under this paragraph unless the Institutional Trustee has
obtained an opinion of tax counsel to the effect that for the purposes of
United States federal income tax the Trust will not be classified as other than
a grantor trust on account of such action.  If the Institutional Trustee fails
to enforce its rights under the Declaration, any Holder of Common Securities
may institute a legal proceeding directly against any Person to enforce the
Institutional Trustee's rights under the Declaration, without first instituting
a legal proceeding against the Institutional Trustee or any other Person.

                 Any approval or direction of Holders of Common Securities may
be given at a separate meeting of Holders of Common Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent.  The Regular Trustees will cause a notice of any
meeting at which Holders of Common Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Common Securities.  Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such Holders are entitled to vote or of
such matter upon which written consent is





                                      I-11
<PAGE>   73
sought and (iii) instructions for the delivery of proxies or consents.

                 No vote or consent of the Holders of the Common Securities
will be required for the Trust to redeem and cancel Common Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                 7.       Amendments to Declaration and Indenture.

                 (a)      In addition to any requirements under Section 12.1 of
the Declaration, if any proposed amendment to the Declaration provides for, or
the Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 of the Declaration, then the Holders of outstanding Securities
voting together as a single class, will be entitled to vote on such amendment
or proposal (but not on any other 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 Securities, affected thereby,
provided, however, if any amendment or proposal referred to in clause (i) above
would adversely affect only the Preferred Securities or only the Common
Securities, then only the affected 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 a Majority in liquidation amount of such class of
Securities.

                 (b)      In the event the consent of the Institutional Trustee
as the holder of the Debentures is required under the Indenture with respect to
any amendment, modification or termination on the Indenture or the Debentures,
the Institutional Trustee shall request the written direction of the Holders of
the Securities with respect to such amendment, modification or termination and
shall vote with respect to such amendment, modification or termination as
directed by a Majority in liquidation amount of the Securities voting together
as a single class; provided, however, that where a consent under the Indenture
would require the consent of the holders of greater than a majority in
aggregate principal amount of the Debentures (a "Super Majority"), the
Institutional Trustee may only give such consent at the direction of the
Holders of at least the proportion in liquidation amount of the Securities
which the relevant Super Majority represents of the aggregate principal amount
of the Debentures outstanding; provided, further, that the Institutional
Trustee shall not take any action in accordance with the directions of the
Holders of the Securities under this Section 7(b) unless the Institutional
Trustee has obtained an opinion of tax counsel to the effect that for the
purposes of United States federal income





                                      I-12
<PAGE>   74
tax the Trust will not be classified as other than a grantor trust on account
of such action.

                 8.       Pro Rata.

                 A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each
Holder of Securities according to the aggregate liquidation amount of the
Securities held by the relevant Holder in relation to the aggregate liquidation
amount of all Securities outstanding unless, in relation to a payment, an Event
of Default under the Declaration has occurred and is continuing, in which case
any funds available to make such payment shall be paid first to each Holder of
the Preferred Securities pro rata according to the aggregate liquidation amount
of Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Preferred Securities, to
each Holder of Common Securities pro rata according to the aggregate
liquidation amount of Common Securities held by the relevant Holder relative to
the aggregate liquidation amount of all Common Securities outstanding.

                 9.       Ranking.

                 The Preferred Securities rank pari passu and payment thereon
shall be made Pro Rata with the Common Securities except that, where a
Declaration Event of Default occurs and is continuing the rights of Holders of
the Common Securities to payment in respect of Distributions and payments upon
liquidation, redemption and otherwise are subordinated to the rights to payment
of the Holders of the Preferred Securities.

                 10.      Listing.

                 The Regular Trustees shall use their best efforts to cause the
Preferred Securities to be listed for quotation on the New York Stock Exchange,
Inc.

                 11.      Acceptance of Securities Guarantee and Indenture.

                 Each Holder of Preferred Securities and Common Securities, by
the acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.

                 12.      No Preemptive Rights.

                 The Holders of the Securities shall have no preemptive rights
to subscribe for any additional securities.

                 The Sponsor will provide a copy of the Declaration, the
Preferred Securities Guarantee or the Common Securities Guarantee (as may be

<PAGE>   78
                         [FORM OF REVERSE OF SECURITY]

                 Distributions payable on each  Preferred Security will be
fixed at a rate per annum of ______% (the "Coupon Rate") of the stated
liquidation amount of $__ per Preferred Security, such rate being the rate of
interest payable on the Debentures to be held by the Institutional Trustee.
Distributions in arrears for more than one quarter will bear interest thereon
compounded quarterly at the Coupon Rate (to the extent permitted by applicable
law).  The term "Distributions" as used herein includes such cash distributions
and any such interest payable unless otherwise stated.  A Distribution is
payable only to the extent that payments are made in respect of the Debentures
held by the Institutional Trustee and to the extent the Institutional Trustee
has funds available therefor.  The amount of Distributions payable for any
period will be computed for any full quarterly Distribution period on the basis
of a 360- day year of twelve 30-day months, and for any period shorter than a
full quarterly Distribution period for which Distributions are computed,
Distributions will be computed on the basis of the actual number of days
elapsed per 90-day quarter.

                 Except as otherwise described below, distributions on the
Preferred Securities will be cumulative, will accrue from the date of original
issuance and will be payable quarterly in arrears, on [March 31, June 30,
September 30 and December 31] of each year, commencing on ________, 1996, to
[Holders of record fifteen (15) days prior to such payment dates, which payment
dates shall correspond to the interest payment dates on the Debentures.]  The
Debenture Issuer has the right under the Indenture to defer payments of
interest by extending the interest payment period from time to time on the
Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period"), provided that no Extension Period shall last beyond the
date of the maturity of the Debentures and as a consequence of such deferral,
Distributions will also be deferred.  Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period. Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity of
the Debentures.  Payments of accrued Distributions will be payable to Holders
as they appear on the books and records of the Trust on the first record date
after the end of the Extension Period.  Upon the termination of any Extension
Period and the payment of all amounts then due, the Debenture Issuer may
commence a new Extension Period, subject to the above requirements.

dated as of _______, 1996, as the same may be amended from time to time (the

as set forth in Annex I to the Declaration.  Capitalized terms used herein but

is entitled to the benefits of the Common Securities Guarantee to the extent
provided therein.  The Sponsor will provide a copy of the Declaration, the

                         [FORM OF REVERSE OF SECURITY]

                 Distributions payable on each Common Security will be fixed at
a rate per annum of ______% (the "Coupon Rate") of the stated liquidation
amount of $__ per Common Security, such rate being the rate of interest payable
on the Debentures to be held by the Institutional Trustee.  Distributions in
arrears for more than one quarter will bear interest thereon compounded
quarterly at the Coupon Rate (to the extent permitted by applicable law).  The
term "Distributions" as used herein includes such cash distributions and any
such interest payable unless otherwise stated.  A Distribution is payable only
to the extent that payments are made in respect of the Debentures held by the
Institutional Trustee and to the extent the Institutional Trustee has funds
available therefor.  The amount of Distributions payable for any period will be
computed for any full quarterly Distribution period on the basis of a 360- day
year of twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 90-day quarter.

                 Except as otherwise described below, distributions on the
Common Securities will be cumulative, will accrue from the date of original
issuance and will be payable quarterly in arrears, on [March 31, June 30,
September 30 and December 31] of each year, commencing on ________, 1996, to
Holders of record fifteen (15) days prior to such payment dates, which payment
dates shall correspond to the interest payment dates on the Debentures.  The
Debenture Issuer has the right under the Indenture to defer payments of
interest by extending the interest payment period from time to time on the
Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period"), provided that no Extension Period shall last beyond the
date of the maturity of the Debentures and as a consequence of such deferral,
Distributions will also be deferred.  Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period. Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity
date of the Debentures.  Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the first
record date after the end of the Extension Period.  Upon the termination of any
Extension Period and the payment of all amounts then due, the Debenture Issuer
may commence a new Extension Period, subject to the above requirements.

SECTION 2.6      Events of Default; Waiver.

                 (a)        The Holders of a Majority in liquidation amount of
Preferred Securities may, by vote, on behalf of the Holders of all of the
Preferred Securities, waive any past Event of Default in respect of the
Preferred Securities and its consequences, provided that, if the underlying
Event of Default under the Indenture:

                 (i)        is not waivable under the Indenture, the Event of
         Default under the Declaration shall also not be waivable; or

                 (ii)       requires the consent or vote of greater than a
         majority in principal amount of the holders of the Debentures (a
         "Super Majority") to be waived under the Indenture, the Event of
         Default under the Declaration may only be waived by the vote of the
         Holders of at least the proportion in liquidation amount of the
         Preferred Securities that the relevant Super Majority represents of
         the aggregate principal amount of the Debentures outstanding.

The foregoing provisions of this Section 2.6(a) shall be in lieu of Section
316(a)(1)(B) of the Trust Indenture Act and such Section  316(a)(1)(B) of the
Trust Indenture Act is hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act.  Upon such waiver, any
such default shall cease to exist, and any Event of Default with respect to the
Preferred Securities arising therefrom shall be deemed to have been cured, for
every purpose of this Declaration, but no such waiver shall extend to any
subsequent or other default or an Event of Default with respect to the
Preferred Securities or impair any right consequent thereon.  Any waiver by the
Holders of the Preferred Securities of an Event of Default with respect to the
Preferred Securities shall also be deemed to constitute a waiver by the Holders
of the Common Securities of any such Event of Default with respect to the
Common Securities for all purposes of this Declaration without any further act,
vote, or consent of the Holders of the Common Securities.

                 (b)        The Holders of a Majority in liquidation amount of
the Common Securities may, by vote, on behalf of the Holders of all of the
Common Securities, waive any past Event of Default with respect to the Common
Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

                 (i)        is not waivable under the Indenture, except where
         the Holders of the Common Securities are deemed to have waived such
         Event of Default under the Declaration as provided below in this
         Section 2.6(b), the Event of Default under the Declaration shall also
         not be waivable; or





                                       10
<PAGE>   16
                 (ii)       requires the consent or vote of a Super Majority to
         be waived, except where the Holders of the Common Securities are
         deemed to have waived such Event of Default under the Declaration as
         provided below in this Section 2.6(b), the Event of Default under the
         Declaration may only be waived by the vote of the Holders of at least
         the proportion in liquidation amount of the Common Securities that the
         relevant Super Majority represents of the aggregate principal amount
         of the Debentures outstanding;

provided further, each Holder of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default with respect to the
Common Securities and its consequences until all Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated,
and until such Events of Default have been so cured, waived or otherwise
eliminated, the Institutional Trustee will be deemed to be acting solely on
behalf of the Holders of the Preferred Securities and only the Holders of the
Preferred Securities will have the right to direct the Institutional Trustee in
accordance with the terms of the Securities.  The foregoing provisions of this
Section 2.6(b) shall be in lieu of Sections  316(a)(1)(A) and 316(a)(1)(B) of
the Trust Indenture Act and such Sections  316(a)(1)(A) and 316(a)(1)(B) of the
Trust Indenture Act are hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act.  Subject to the foregoing
provisions of this Section 2.6(b), upon such waiver, any such default shall
cease to exist and any Event of Default with respect to the Common Securities
arising therefrom shall be deemed to have been cured for every purpose of this
Declaration, but no such waiver shall extend to any subsequent or other default
or Event of Default with respect to the Common Securities or impair any right
consequent thereon.

                 (c)        A waiver of an Event of Default under the Indenture
by the Institutional Trustee at the direction of the Holders of the Preferred
Securities, constitutes a waiver of the corresponding Event of Default under
this Declaration.  The foregoing provisions of this Section 2.6(c) shall be in
lieu of Section  316(a)(1)(B) of the Trust Indenture Act and such Section
316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this
Declaration and the Securities, as permitted by the Trust Indenture Act.

SECTION 2.7      Event of Default; Notice.

                 (a)        The Institutional Trustee shall, within 90 days
after the occurrence of an Event of Default, transmit by mail, first class
postage prepaid, to the Holders of the Securities, notices of all defaults with
respect to the Securities actually known to a Responsible Officer of the
Institutional Trustee, unless such defaults have been cured before the giving
of such





                                       11
<PAGE>   17
notice (the term "defaults" for the purposes of this Section 2.7(a) being
hereby defined to be an Event of Default as defined in the Indenture, not
including any periods of grace provided for therein and irrespective of the
giving of any notice provided therein); provided that, except for a default in
the payment of principal of (or premium, if any) or interest on any of the
Debentures or in the payment of any sinking fund installment established for
the Debentures, the Institutional Trustee shall be protected in withholding
such notice if and so long as a Responsible Officer of the Institutional
Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders of the Securities.

                 (b)        The Institutional Trustee shall not be deemed to
have knowledge of any default except:

                 (i)        a default under Sections ____ and ____ of the
         Indenture; or

                 (ii)       any default as to which the Institutional Trustee
         shall have received written notice or of which a Responsible Officer
         of the Institutional Trustee charged with the administration of the
         Declaration shall have actual knowledge.

                 (vii)      other than as provided in this Amended and Restated
Declaration or Annex I, (A) direct the time, method and place of exercising any
trust or power conferred upon the Debenture Trustee with respect to the
Debentures, (B) waive any past default that is waivable under the Indenture,
(C) exercise any right to rescind or annul any declaration that the principal
of all the Debentures shall be due and payable, or (D) consent to any
amendment, modification or termination of the Indenture or the Debentures where
such consent shall be required unless the Trust shall have received an opinion
of counsel to the effect that such modification will not cause more than an
insubstantial risk that for United States federal income tax purposes the Trust
will not be classified as a grantor trust.

SECTION 3.8      Powers and Duties of the Institutional Trustee.

                 (a)        The legal title to the Debentures shall be owned by
and held of record in the name of the Institutional Trustee in trust for the
benefit of the Holders of the Securities.  The right, title and interest of the
Institutional Trustee to the Debentures shall vest automatically in each Person
who may hereafter be appointed as Institutional Trustee in accordance with
Section 5.7.  Such vesting and cessation of title shall be effective whether or
not conveyancing documents with regard to the Debentures have been executed and
delivered.

                 (b)        The Institutional Trustee shall not transfer its
right, title and interest in the Debentures to the Regular Trustees or to the
Delaware Trustee (if the Institutional Trustee does not also act as Delaware
Trustee).

                 (c)        The Institutional Trustee shall:

                 (i)        establish and maintain a segregated non-interest
         bearing trust account (the "Institutional Trustee Account")





                                       17
<PAGE>   23
         in the name of and under the exclusive control of the Institutional
         Trustee on behalf of the Holders of the Securities and, upon the
         receipt of payments of funds made in respect of the Debentures held by
         the Institutional Trustee, deposit such funds into the Institutional
         Trustee Account and make payments to the Holders of the Preferred
         Securities and Holders of the Common Securities from the Institutional
         Trustee Account in accordance with Section 6.1.  Funds in the
         Institutional Trustee Account shall be held uninvested until disbursed
         in accordance with this Declaration.  The Institutional Trustee
         Account shall be an account that is maintained with a banking
         institution the rating on whose long-term unsecured indebtedness is at
         least equal to the rating assigned to the Preferred Securities by a
         "nationally recognized statistical rating organization", as that term
         is defined for purposes of Rule 436(g)(2) under the Securities Act;

                 (ii)       engage in such ministerial activities as shall be
         necessary or appropriate to effect the redemption of the Preferred
         Securities and the Common Securities to the extent the Debentures are
         redeemed or mature; and

                 (iii)      upon written notice of distribution issued by the
         Regular Trustees in accordance with the terms of the Securities,
         engage in such ministerial activities as shall be necessary or
         appropriate to effect the distribution of the Debentures to Holders of
         Securities upon the occurrence of certain special events (as may be
         defined in the terms of the Securities) arising from a change in law
         or a change in legal interpretation or other specified circumstances
         pursuant to the terms of the Securities.

                 (d)        The Institutional Trustee shall take all actions
and perform such duties as may be specifically required of the Institutional
Trustee pursuant to the terms of the Securities.

                 (e)        The Institutional Trustee shall take any Legal
Action which arises out of or in connection with an Event of Default of which a
Responsible Officer of the Institutional Trustee has actual knowledge or the
Institutional Trustee's duties and obligations under this Declaration or the
Trust Indenture Act; provided however, that if a Declaration Event of Default
has occurred and is continuing and such event is attributable to the failure of
the Debenture Issuer to pay interest or principal on the Debentures on the date
such interest or principal is otherwise payable (or in the case of redemption,
on the redemption date), then a Holder of Preferred Securities may directly
institute a proceeding for enforcement of payment to such Holder of the
principal of or interest on the Debentures having a principal amount equal to
the aggregate liquidation amount of the Preferred Securities of such Holder (a
"Direct





                                       18
<PAGE>   24
Action") on or after the respective due date specified in the Debentures.  In
connection with such Direct Action, the rights of the Holders of the Common
Securities Holder will be subrogated to the rights of such Holder of Preferred
Securities to the extent of any payment made by the Issuer to such Holder of
Preferred Securities in such Direct Action.  Except as provided in the
preceding sentences, the Holders of Preferred Securities will not be able to
exercise directly any other remedy available to the holders of the Debentures.

                 (f)        The Institutional Trustee shall not resign as a
Trustee unless either:

                 (i)        the Trust has been completely liquidated and the
         proceeds of the liquidation distributed to the Holders of Securities
         pursuant to the terms of the Securities; or

                 (ii)       a Successor Institutional Trustee has been
         appointed and has accepted that appointment in accordance with Section
         5.7.

                 (g)        The Institutional Trustee shall have the legal
power to exercise all of the rights, powers and privileges of a holder of
Debentures under the Indenture and, if an Event of Default actually known to a
Responsible Officer of the Institutional Trustee occurs and is continuing, the
Institutional Trustee shall, for the benefit of Holders of the Securities,
enforce its rights as holder of the Debentures subject to the rights of the
Holders pursuant to the terms of such Securities.

                 (h)        The Institutional Trustee may authorize one or more
Persons (each, a "Paying Agent") to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all securities and
any such Paying Agent shall comply with Section  317(b) of the Trust Indenture
Act.  Any Paying Agent may be removed by the Institutional Trustee at any time
and a successor Paying Agent or additional Paying Agents may be appointed at
any time by the Institutional Trustee.

                 (i)        Subject to this Section 3.8, the Institutional
Trustee shall have none of the duties, liabilities, powers or the authority of
the Regular Trustees set forth in Section 3.6.

                 The Institutional Trustee must exercise the powers set forth
in this Section 3.8 in a manner that is consistent with the purposes and
functions of the Trust set out in Section 3.3, and the Institutional Trustee
shall not take any action that is inconsistent with the purposes and functions
of the Trust set out in Section 3.3.

SECTION 3.9      Certain Duties and Responsibilities of the Institutional
                 Trustee.

                 (a)        The Institutional 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 Declaration and no implied covenants shall be read into this
Declaration against the Institutional Trustee.  In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6) of which a
Responsible Officer of the Institutional Trustee has actual knowledge, the
Institutional Trustee shall exercise such of the rights and powers vested in it
by this Declaration, 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 or her own affairs.

                 (b)        No provision of this Declaration shall be construed
to relieve the Institutional 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 an 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
                 Institutional Trustee shall be determined solely by the
                 express provisions of this Declaration and the Institutional
                 Trustee shall not be liable except for the performance of such
                 duties and obligations as are specifically set forth in this
                 Declaration, and no implied covenants or obligations shall be
                 read into this Declaration against the Institutional Trustee;
                 and

                            (B)     in the absence of bad faith on the part of
                 the Institutional Trustee, the Institutional 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 Institutional
                 Trustee and conforming to the requirements of this
                 Declaration; but in the case of any such certificates or
                 opinions that by any provision hereof are specifically
                 required to be furnished to the Institutional Trustee, the
                 Institutional Trustee shall be under a duty to examine the
                 same to determine whether or not they conform to the
                 requirements of this Declaration;

                 (ii)       the Institutional Trustee shall not be liable for
         any error of judgment made in good faith by a Responsible Officer of
         the Institutional Trustee, unless it shall be





                                       20
<PAGE>   26
         proved that the Institutional Trustee was negligent in ascertaining
         the pertinent facts;

                 (iii)      the Institutional 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 Securities relating to the time,
         method and place of conducting any proceeding for any remedy available
         to the Institutional Trustee, or exercising any trust or power
         conferred upon the Institutional Trustee under this Declaration;

                 (iv)       no provision of this Declaration shall require the
         Institutional Trustee to expend or risk its own funds or otherwise
         incur personal financial liability in the performance of any of its
         duties or in the exercise of any of its rights or powers, if it shall
         have reasonable grounds for believing that the repayment of such funds
         or liability is not reasonably assured to it under the terms of this
         Declaration or indemnity reasonably satisfactory to the Institutional
         Trustee against such risk or liability is not reasonably assured to
         it;

                 (v)        the Institutional Trustee's sole duty with respect
         to the custody, safe keeping and physical preservation of the
         Debentures and the Institutional Trustee Account shall be to deal with
         such property in a similar manner as the Institutional Trustee deals
         with similar property for its own account, subject to the protections
         and limitations on liability afforded to the Institutional Trustee
         under this Declaration and the Trust Indenture Act;

                 (vi)       the Institutional Trustee shall have no duty or
         liability for or with respect to the value, genuineness, existence or
         sufficiency of the Debentures or the payment of any taxes or
         assessments levied thereon or in connection therewith;

                 (vii)      the Institutional Trustee shall not be liable for
         any interest on any money received by it except as it may otherwise
         agree with the Sponsor.  Money held by the Institutional Trustee need
         not be segregated from other funds held by it except in relation to
         the Institutional Trustee Account maintained by the Institutional
         Trustee pursuant to Section 3.8(c)(i) and except to the extent
         otherwise required by law; and

                 (viii) the Institutional Trustee shall not be responsible for
         monitoring the compliance by the Regular Trustees or the Sponsor with
         their respective duties under this Declaration, nor shall the
         Institutional Trustee be liable for any





                                       21

         default or misconduct of the Regular Trustees or the Sponsor.

                 (i)        the Institutional Trustee may conclusively rely and

         other evidence of indebtedness or other paper or document believed by

         hereunder, the Institutional Trustee (unless other evidence is herein
         specifically prescribed) may, in the absence of bad faith on its part,

         Sponsor or the Regular Trustees;

         competent jurisdiction;

                 (vi)       the Institutional Trustee shall be under no

         unless such Holder shall have provided to the Institutional Trustee

         Trustee, against the costs, expenses (including attorneys' fees and
         expenses and the expenses of the Institutional Trustee's agents,
         nominees or custodians) 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 Institutional Trustee provided,
         that, nothing contained in this Section 3.10(a)(vi) shall be taken to

         it by this Declaration;

                 (vii)      the Institutional Trustee shall not be bound to
         make any investigation into the facts or matters stated in any

         notice, request, direction, consent, order, bond, debenture, note,
         other evidence of indebtedness or other paper or document, but the
         Institutional Trustee, in its discretion, may make such further
         inquiry or investigation into such facts or matters as it may see fit;

                 (viii) the Institutional Trustee may execute any of the trusts

                 (ix)       any action taken by the Institutional Trustee or
         its agents hereunder shall bind the Trust and the Holders of the
         Securities, and the signature of the Institutional Trustee or its
         agents alone shall be sufficient and effective to perform any such
         action and no third party shall be required to inquire as to the
         authority of the Institutional Trustee to so act or as to its
         compliance with any of the terms and provisions of this Declaration,
         both of which shall be conclusively evidenced by the Institutional
         Trustee's or its agent's taking such action;

                 (x)        whenever in the administration of this Declaration
         the Institutional Trustee shall deem it desirable to receive
         instructions with respect to enforcing any remedy or right or taking
         any other action hereunder, the Institutional Trustee (i) may request
         instructions from the Holders of the Securities which instructions may
         only be given by the Holders of the same proportion in liquidation
         amount of the Securities as would be entitled to direct the
         Institutional Trustee under the terms of the Securities in respect of
         such





                                       23
<PAGE>   29
         remedy, right or action, (ii) may refrain from enforcing such remedy

                 (b)        No provision of this Declaration shall be deemed to
impose any duty or obligation on the Institutional 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
Institutional 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
Institutional Trustee shall be construed to be a duty.

Trustee is authorized to execute on behalf of the Trust any documents that the

Regular Trustees.

SECTION 3.13     Not Responsible for Recitals or Issuance of Securities.

                 The recitals contained in this Declaration and the Securities
shall be taken as the statements of the Sponsor, and the Trustees do not assume

as to the value or





                                       24
<PAGE>   30
condition of the property of the Trust or any part thereof.  The Trustees make
no representations as to the validity or sufficiency of this Declaration or the
Securities.

SECTION 3.14     Duration of Trust.

                 The Trust, unless terminated pursuant to the provisions of

                 (a)        The Trust may not consolidate, amalgamate, 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 body,
except as described in Section 3.15(b) and (c).

                 (b)        The Trust may, with the consent of the Regular
Trustees or, if there are more than two, a majority of the Regular Trustees and
without the consent of the Holders of the Securities, the Delaware Trustee or
the Institutional Trustee, consolidate, amalgamate, merge with or into, or be
replaced by a trust organized as such under the laws of any State; provided
that:

                 (i)        such successor entity (the "Successor Entity")
         either:

                            (A)     expressly assumes all of the obligations 
                 of the Trust under the Securities; or

                            (B)     substitutes for the 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 with respect to Distributions and payments
                 upon liquidation, redemption and otherwise;

                 (ii)       the Debenture Issuer expressly acknowledges a
         trustee of the Successor Entity that possesses the same powers and
         duties as the Institutional Trustee as the Holder of the Debentures;

                 (iii)      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;





                                       25
<PAGE>   31
                 (iv)       such merger, consolidation, amalgamation or
         replacement does not cause the Preferred Securities (including any
         Successor Securities) to be downgraded by any nationally recognized
         statistical rating organization;

                 (v)        such merger, consolidation, amalgamation or
         replacement does not adversely affect the rights, preferences and
         privileges of the Holders of the  Securities (including any Successor
         Securities) in any material respect (other than with respect to any
         dilution of such Holders' interests in the Preferred Securities as a
         result of such merger, consolidation, amalgamation or replacement);

                 (vi)       such Successor Entity has a purpose identical to
         that of the Trust;

                 (vii)      prior to such merger, consolidation, amalgamation
         or replacement, the Sponsor has received an opinion of a nationally
         recognized independent counsel to the Trust experienced in such
         matters to the effect that:

                            (A)     such merger, consolidation, amalgamation or
                 replacement does not adversely affect the rights, preferences
                 and privileges of the Holders of the Securities (including any
                 Successor Securities) in any material respect (other than with
                 respect to any dilution of the Holders' interest in the new
                 entity); and

                            (B)     following such merger, consolidation,
                 amalgamation or replacement, neither the Trust nor the
                 Successor Entity will be required to register as an Investment
                 Company;

                            (C)     following such merger, consolidation,
                 amalgamation or replacement, the Trust (or the Successor
                 Entity) will continue to be classified as a grantor trust for
                 United States federal income tax purposes; and

                 (viii) the Sponsor guarantees the obligations of such
         Successor Entity under the Successor Securities at least to the extent
         provided by the Preferred Securities Guarantees.

                 (c)        Notwithstanding Section 3.15(b), the Trust shall
not, except with the consent of Holders of 100% in liquidation amount of the
Securities, consolidate, amalgamate, merge with or into, or be replaced by any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger or
replacement would cause the Trust or Successor Entity to be classified as other
than a grantor trust for United States federal income tax purposes.

         surplus as set forth in its most recent report of condition so

however, that:

         Institutional Trustee shall be effective:

                            (A)     until a Successor Institutional Trustee has
                 been appointed and has accepted such appointment by instrument
                 executed by such Successor Institutional Trustee and delivered
                 to the Trust, the Sponsor and the resigning Institutional
                 Trustee; or

                            (B)     until the assets of the Trust have been
                 completely liquidated and the proceeds thereof distributed to
                 the holders of the Securities; and

                 (ii)       no such resignation of the Trustee that acts as the

Delaware Trustee shall have been appointed and accepted appointment as provided

of an instrument of resignation, the resigning Institutional Trustee or
Delaware Trustee, as applicable, may petition any court of competent
jurisdiction for appointment of a Successor Institutional Trustee or Successor
Delaware Trustee.  Such court may thereupon, after prescribing such notice, if
any, as it may deem proper and prescribe, appoint a Successor Institutional
Trustee or Successor Delaware Trustee, as the case may be.

                 (f)        No Institutional Trustee or Delaware Trustee shall
be liable for the acts or omissions to act of any Successor Institutional
Trustee or successor Delaware Trustee, as the case may be.

SECTION 5.8      Vacancies among Trustees.

                 If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 5.1, or if the number of
Trustees is increased pursuant to Section 5.1, a vacancy shall occur.  A
resolution certifying the existence of such vacancy by the Regular Trustees or,
if there are more than two, a majority of the Regular Trustees shall be
conclusive evidence of the existence of such vacancy.  The vacancy shall be
filled with a Trustee appointed in accordance with Section 5.7.

SECTION 5.9      Effect of Vacancies.

                 The death, resignation, retirement, removal, bankruptcy,

Trustee shall not operate to annul the Trust.  Whenever a vacancy in the number
of Regular Trustees shall occur, until such vacancy is filled by the
appointment of a Regular Trustee in accordance with Section 5.7, the Regular
Trustees in office, regardless of their number, shall have all the powers
granted to the Regular Trustees and shall discharge all the duties imposed upon
the Regular Trustees by this Declaration.

SECTION 5.10     Meetings.

                 If there is more than one Regular Trustee, meetings of the
Regular Trustees shall be held from time to time upon the call of any Regular
Trustee.  Regular meetings of the Regular Trustees may be held at a time and
place fixed by resolution of the Regular Trustees.  Notice of any in-person
meetings of the Regular Trustees shall be hand delivered or otherwise delivered
in writing (including by facsimile, with a hard copy by overnight courier) not
less than 48 hours before such meeting.  Notice of any telephonic meetings of
the Regular Trustees or any committee





                                       32
<PAGE>   38
thereof shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours before
a meeting.  Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting.  The presence (whether in person or by
telephone) of a Regular Trustee at a meeting shall constitute a waiver of
notice of such meeting except where a Regular Trustee attends a meeting for the
express purpose of objecting to the transaction of any activity on the ground
that the meeting has not been lawfully called or convened.  Unless provided
otherwise in this Declaration, any action of the Regular Trustees may be taken
at a meeting by vote of a majority of the Regular Trustees present (whether in
person or by telephone) and eligible to vote with respect to such matter,
provided that a Quorum is present, or without a meeting by the unanimous
written consent of the Regular Trustees.  In the event there is only one
Regular Trustee, any and all action of such Regular Trustee shall be evidenced
by a written consent of such Regular Trustee.

SECTION 5.11     Delegation of Power.

                 (a)        Any Regular 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 3.6, including any registration statement or amendment
thereto filed with the Commission, or making any other governmental filing; and

                 (b)        the Regular Trustees shall have power to delegate
from time to time to such of their number or to officers of the Trust the doing
of such things and the execution of such instruments either in the name of the
Trust or the names of the Regular Trustees or otherwise as the Regular Trustees
may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

Section 5.12     Merger, Conversion, Consolidation or Succession to Business.

         Any corporation into which the Institutional Trustee or the Delaware
Trustee, as the case may be, may be merged or converted or with which either
may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Institutional Trustee or the Delaware Trustee, as
the case may be, shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Institutional Trustee or
the Delaware Trustee, as the case may be, shall be the successor of the
Institutional Trustee or the Delaware Trustee, as the case may be, hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article,





                                       33

accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Preferred Securities and the Common
Securities in accordance with the preferences set forth in their respective

interest (including Compounded Interest (as defined in the Indenture) and
Additional Interest (as defined in the Indenture)), premium and/or principal on
the Debentures held by the Institutional Trustee (the amount of any such
payment being a "Payment Amount"), the Institutional Trustee shall and is
directed, to the extent funds are available for that purpose, to make a
distribution (a "Distribution") of the Payment Amount to Holders.


                                  ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1      General Provisions Regarding Securities.

                 (a)        The Regular Trustees shall on behalf of the Trust
issue one class of preferred securities representing undivided beneficial
interests in the assets of the Trust having such terms as are set forth in
Annex I (the "Preferred Securities") and one class of common securities
representing undivided beneficial interests in the assets of the Trust having
such terms as are set forth in Annex I (the "Common Securities.")  The Trust
shall issue no securities or other interests in the assets of the Trust other
than the Preferred Securities and the Common Securities.

                 (b)        The Certificates shall be signed on behalf of the
Trust by a Regular Trustee.  Such signature shall be the manual signature of
any present or any future Regular Trustee.  In case any Regular Trustee of the
Trust who shall have signed any of the Securities shall cease to be such
Regular Trustee before the Certificates so signed shall be delivered by the
Trust, such Certificates nevertheless may be delivered as though the person who
signed such Certificates had not ceased to be such Regular Trustee; and any
Certificate may be signed on behalf of the Trust by such persons who, at the
actual date of execution of such Security, shall be the Regular Trustees of the
Trust, although at the date of the execution and delivery of the Declara-





                                       34
<PAGE>   40
tion any such person was not such a Regular Trustee.  Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Regular Trustees, as evidenced by their execution
thereof, and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements as the Regular Trustees may deem
appropriate, or as may be required to comply with any law or with any rule or
regulation of any stock exchange on which Securities may be listed, or to
conform to usage.

                 (c)        The consideration received by the Trust for the
issuance of the Securities shall constitute a contribution to the capital of
the Trust and shall not constitute a loan to the Trust.

                 (d)        Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable.

                 (e)        Every Person, by virtue of having become a Holder
or a Preferred Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration.

SECTION 7.2      Paying Agent.

                 In the event that the Preferred Securities are not in
book-entry only form, the Trust shall maintain in the Borough of Manhattan,
City of New York, State of New York, an office or agency where the Preferred
Securities may be presented for payment ("Paying Agent).  The Trust may appoint
the Paying Agent and may appoint one or more additional paying agents in such
other locations as it shall determine.  The term "Paying Agent" includes any
additional paying agent.  The Trust may change any Paying Agent without prior
notice to any Holder.  The Trust shall notify the Institutional Trustee of the
name and address of any Agent not a party to this Declaration.  If the Trust
fails to appoint or maintain another entity as Paying Agent, the Institutional
Trustee shall act as such.  The Trust or any of its Affiliates may act as
Paying Agent.  The Trust shall initially act as Paying Agent for the Preferred

         its equivalent with respect to the Sponsor; the filing of a
         certificate of cancellation with respect to the Trust after having
         obtained the consent of a majority in liquidation amount of the
         Securities voting together as a single class to file such certificate
         of cancellation or the revocation of the Sponsor's charter and the
         expiration of 90 days after the date of revocation without a
         reinstatement thereof;

                 (iii)      upon the entry of a decree of judicial dissolution

                 (iv)       when all of the Securities shall have been called
         for redemption and the amounts necessary for redemption thereof shall
         have been paid to the Holders in accordance with the terms of the
         Securities;

                 (v)        upon the occurrence and continuation of a Special
         Event pursuant to which the Trust shall have been dissolved in
         accordance with the terms of the Securities and all of the Debentures
         endorsed thereon shall have been distributed to the Holders of
         Securities in exchange for all of the Securities; or

                 (vi)       before the issuance of any Securities, with the
         consent of all of the Regular Trustees and the Sponsor.

                 (b)        As soon as is practicable after the occurrence of

survive the termination of the Trust.

                             TRANSFER OF INTERESTS

SECTION 9.1      Transfer of Securities.

                 (a)        Securities may only be transferred, in whole or in
part, in accordance with the terms and conditions set forth in this Declaration
and in the terms of the Securities.  Any transfer or purported transfer of any
Security not made in accordance with this Declaration shall be null and void.





                                       36

                 (b)        Subject to this Article IX, Preferred Securities
shall be freely transferable.

                 (c)        The Sponsor may not transfer the Common Securities.

SECTION 9.2      Transfer of Certificates.

                 The Regular Trustees shall provide for the registration of
Certificates and of transfers of Certificates, which will be effected without
charge but only upon payment (with such indemnity as the Regular Trustees may
require) in respect of any tax or other government charges that may be imposed
in relation to it.  Upon surrender for registration of transfer of any
Certificate, the Regular Trustees shall cause one or more new Certificates to
be issued in the name of the designated transferee or transferees.  Every
Certificate surrendered for registration of transfer shall be accompanied by a
written instrument of transfer in form satisfactory to the Regular Trustees
duly executed by the Holder or such Holder's attorney duly authorized in
writing.  Each Certificate surrendered for registration of transfer shall be
canceled by the Regular Trustees.  A transferee of a Certificate shall be
entitled to the rights and subject to the obligations of a Holder hereunder
upon the receipt by such transferee of a Certificate.  By acceptance of a
Certificate, each transferee shall be deemed to have agreed to be bound by this
Declaration.

SECTION 9.3      Deemed Security Holders.

                 The Trustees may treat the Person in whose name any
Certificate shall be registered on the books and records of the Trust as the
sole holder of such Certificate and of the Securities represented by such
Certificate for purposes of receiving Distributions and for all other purposes
whatsoever and, accordingly, shall not be bound to recognize any equitable or
other claim to or interest in such Certificate or in the Securities represented
by such Certificate on the part of any Person, whether or not the Trust shall
have actual or other notice thereof.

SECTION 9.4      Book Entry Interests.

                 Unless otherwise specified in the terms of the Preferred
Securities, the Preferred Securities Certificates, on original issuance, will
be issued in the form of one or more, fully registered, global Preferred
Security Certificates (each a "Global Certificate"), to be delivered to DTC,
the initial Clearing Agency, by, or on behalf of, the Trust.  Such Global
Certificates shall initially be registered on the books and records of the
Trust in the name of Cede & Co., the nominee of DTC, and no Preferred Security
Beneficial Owner will receive a definitive





                                       37
<PAGE>   43
Preferred Security Certificate representing such Preferred Security Beneficial
Owner's interests in such Global Certifi- cates, except as provided in Section
9.7.  Unless and until definitive, fully registered Preferred Security
Certificates (the "Definitive Preferred Security Certificates") have been
issued to the Preferred Security Beneficial Owners pursuant to Section 9.7:

                 (a)        the provisions of this Section 9.4 shall be in full
         force and effect;

                 (b)        the Trust and the Trustees shall be entitled to
         deal with the Clearing Agency for all purposes of this Declaration
         (including the payment of Distributions on the Global Certificates and
         receiving approvals, votes or consents hereunder) as the Holder of the
         Preferred Securities and the sole holder of the Global Certificates
         and shall have no obligation to the Preferred Security Beneficial
         Owners;

                 (c)        to the extent that the provisions of this Section
         9.4 conflict with any other provisions of this Declaration, the
         provisions of this Section 9.4 shall control; and

                 (d)        the rights of the Preferred Security Beneficial
         Owners shall be exercised only through the Clearing Agency and shall
         be limited to those established by law and agreements between such
         Preferred Security Beneficial Owners and the Clearing Agency and/or
         the Clearing Agency Participants and receive and transmit payments of
         Distributions on the Global Certificates to such Clearing Agency
         Participants.  DTC will make book entry transfers among the Clearing
         Agency Participants.

SECTION 9.5      Notices to Clearing Agency.

                 Whenever a notice or other communication to the Preferred
Security Holders is required under this Declaration, unless and until
Definitive Preferred Security Certificates shall have been issued to the
Preferred Security Beneficial Owners pursuant to Section 9.7, the Regular
Trustees shall give all such notices and communications specified herein to be
given to the Preferred Security Holders to the Clearing Agency, and shall have
no notice obligations to the Preferred Security Beneficial Owners.

SECTION 9.6      Appointment of Successor Clearing Agency.

                 If any Clearing Agency elects to discontinue its services as
securities depositary with respect to the Preferred Securities, the Regular
Trustees may, in their sole discretion, appoint a successor Clearing Agency
with respect to such Preferred Securities.





                                       38
<PAGE>   44
SECTION 9.7      Definitive Preferred Security Certificates.

                 If:

                 (a)        a Clearing Agency elects to discontinue its
         services as securities depositary with respect to the Preferred
         Securities and a successor Clearing Agency is not appointed within 90
         days after such discontinuance pursuant to Section 9.6; or

                 (b)        the Regular Trustees elect after consultation with
         the Sponsor to terminate the book entry system through the Clearing
         Agency with respect to the Preferred Securities,

then:

                 (c)        Definitive Preferred Security Certificates shall be
         prepared by the Regular Trustees on behalf of the Trust with respect
         to such Preferred Securities; and

                 (d)        upon surrender of the Global Certificates by the
         Clearing Agency, accompanied by registration instructions, the Regular
         Trustees shall cause Definitive Certificates to be delivered to
         Preferred Security Beneficial Owners in accordance with the
         instructions of the Clearing Agency.  Neither the Trustees nor the
         Trust shall be liable for any delay in delivery of such instructions
         and each of them may conclusively rely on and shall be protected in
         relying on, said instructions of the Clearing Agency.  The Definitive
         Preferred Security Certificates shall be printed, lithographed or
         engraved or may be produced in any other manner as is reasonably
         acceptable to the Regular Trustees, as evidenced by their execution
         thereof, and may have such letters, numbers or other marks of
         identification or designation and such legends or endorsements as the
         Regular Trustees may deem appropriate, or as may be required to comply
         with any law or with any rule or regulation made pursuant thereto or
         with any rule or regulation of any stock exchange on which Preferred
         Securities may be listed, or to conform to usage.

SECTION 9.8      Mutilated, Destroyed, Lost or Stolen Certificates.

                 If:

                 (a)        any mutilated Certificates should be surrendered to
         the Regular Trustees, or if the Regular Trustees shall receive
         evidence to their satisfaction of the destruction, loss or theft of
         any Certificate; and





                                       39
<PAGE>   45
                 (b)        there shall be delivered to the Regular Trustees
         such security or indemnity as may be required by them to keep each of
         them harmless.

then, in the absence of notice that such Certificate shall have been acquired
by a bona fide purchaser, any Regular Trustee on behalf of the Trust shall
execute and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate of like denomination.
In connection with the issuance of any new Certificate under this Section 9.8,
the Regular Trustees 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 Certificate issued pursuant to this Section shall constitute
conclusive evidence of an ownership interest in the relevant Securities, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

                           LIMITATION OF LIABILITY OF
                   HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1     Liability.

                 (a)        Except as expressly set forth in this Declaration,
the Securities Guarantees and the terms of the Securities, the Sponsor shall
not be:

                 (i)        personally liable for the return of any portion of
         the capital contributions (or any return thereon) of the Holders of
         the Securities which shall be made solely from assets of the Trust;
         and

                 (ii)       be required to pay to the Trust or to any Holder of
         Securities any deficit upon dissolution of the Trust or otherwise.

                 (b)        The Holder of the Common Securities shall be liable
for all of the debts and obligations of the Trust (other than with respect to
the Securities) to the extent not satisfied out of the Trust's assets.

                 (c)        Pursuant to Section  3803(a) of the Business Trust
Act, the Holders of the Preferred Securities 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.

SECTION 10.2     Exculpation.





                                       40
<PAGE>   46
                 (a)        No Indemnified Person shall be liable, responsible
or accountable in damages or otherwise to the Trust or any Covered Person for
any loss, damage or claim incurred by reason of 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 the authority conferred on such Indemnified Person by this Declaration or by
law, except that an Indemnified Person shall be liable for any such loss,
damage or claim incurred by reason of such Indemnified Person's gross
negligence or willful misconduct with respect to such acts or omissions.

                 (b)        An Indemnified Person shall be fully protected in
relying in good faith upon the records of the Trust and upon such information,
opinions, reports or statements presented to the Trust by any Person as to
matters the Indemnified Person reasonably believes are within such other
Person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any other facts pertinent to the existence and amount of
assets from which Distributions to Holders of Securities might properly be
paid.

SECTION 10.3     Fiduciary Duty.

                 (a)        To the extent that, at law or in equity, an
Indemnified Person has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to any other Covered Person, an Indemnified
Person acting under this Declaration shall not be liable to the Trust or to any
other Covered Person for its good faith reliance on the provisions of this
Declaration.  The provisions of this Declaration, to the extent that they
restrict the duties and liabilities of an Indemnified Person otherwise existing
at law or in equity (other than the duties imposed on the Institutional Trustee
under the Trust Indenture Act), are agreed by the parties hereto to replace
such other duties and liabilities of such Indemnified Person.

                 (b)        Unless otherwise expressly provided herein:

                 (i)        whenever a conflict of interest exists or arises
         between any Covered Persons; or

                 (ii)       whenever this Declaration or any other agreement
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such
action or provide such terms, considering in each case





                                       41
<PAGE>   47
the relative interest of each party (including its own interest) to such
conflict, agreement, transaction or situation and the benefits and burdens
relating to such interests, any customary or accepted industry practices, and
any applicable generally accepted accounting practices or principles.  In the
absence of bad faith by the Indemnified Person, the resolution, action or term
so made, taken or provided by the Indemnified Person shall not constitute a
breach of this Declaration or any other agreement contemplated herein or of any
duty or obligation of the Indemnified Person at law or in equity or otherwise.

                 (c)        Whenever in this Declaration an Indemnified Person
is permitted or required to make a decision:

                 (i)        in its "discretion" or under a grant of similar
         authority, the Indemnified Person shall be entitled to consider such
         interests and factors as it desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

                 (ii)       in its "good faith" or under another express
         standard, the Indemnified Person shall act under such express standard
         and shall not be subject to any other or different standard imposed by
         this Declaration or by applicable law.

SECTION 10.4     Indemnification.

                 (a) (i)   The Debenture Issuer shall indemnify, to the full
extent permitted by law, any Company Indemnified Person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Trust) by reason
of the fact that he is or was a Company Indemnified Person against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Trust, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful.  The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the Company
Indemnified Person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the Trust,
and, with respect to any criminal action or proceeding, had reasonable cause to
believe that his conduct was unlawful.





                                       42
<PAGE>   48
                 (ii)       The Debenture Issuer shall indemnify, to the full
         extent permitted by law, any Company Indemnified Person who was or is
         a party or is threatened to be made a party to any threatened, pending
         or completed action or suit by or in the right of the Trust to procure
         a judgment in its favor by reason of the fact that he is or was a
         Company Indemnified Person against expenses (including attorneys'
         fees) actually and reasonably incurred by him in connection with the
         defense or settlement of such action or suit if he acted in good faith
         and in a manner he reasonably believed to be in or not opposed to the
         best interests of the Trust and except that no such indemnification
         shall be made in respect of any claim, issue or matter as to which
         such Company Indemnified Person shall have been adjudged to be liable
         to the Trust unless and only to the extent that the Court of Chancery
         of Delaware or the court in which such action or suit was brought
         shall determine upon application that, despite the adjudication of
         liability but in view of all the circumstances of the case, such
         person is fairly and reasonably entitled to indemnity for such
         expenses which such Court of Chancery or such other court shall deem
         proper.

                 (iii)      To the extent that a Company Indemnified Person
         shall be successful on the merits or otherwise (including dismissal of
         an action without prejudice or the settlement of an action without
         admission of liability) in defense of any action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 10.4(a), or in
         defense of any claim, issue or matter therein, he shall be
         indemnified, to the full extent permitted by law, against expenses
         (including attorneys' fees) actually and reasonably incurred by him in
         connection therewith.

                 (iv)       Any indemnification under paragraphs (i) and (ii)
         of this Section 10.4(a) (unless ordered by a court) shall be made by
         the Debenture Issuer only as authorized in the specific case upon a
         determination that indemnification of the Company Indemnified Person
         is proper in the circumstances because he has met the applicable
         standard of conduct set forth in paragraphs (i) and (ii).  Such
         determination shall be made (1) by the Regular Trustees by a majority
         vote of a quorum consisting of such Regular Trustees who were not
         parties to such action, suit or proceeding, (2) if such a quorum is
         not obtainable, or, even if obtainable, if a quorum of disinterested
         Regular Trustees so directs, by independent legal counsel in a written
         opinion, or (3) by the Common Security Holder of the Trust.

                 (v)        Expenses (including attorneys' fees) incurred by a
         Company Indemnified Person in defending a civil, criminal,
         administrative or investigative action, suit or proceeding referred to
         in paragraphs (i) and (ii) of this Section





                                       43
<PAGE>   49
         10.4(a) shall be paid by the Debenture Issuer in advance of the final
         disposition of such action, suit or proceeding upon receipt of an
         undertaking by or on behalf of such Company Indemnified Person to
         repay such amount if it shall ultimately be determined that he is not
         entitled to be indemnified by the Debenture Issuer as authorized in
         this Section 10.4(a).  Notwithstanding the foregoing, no advance shall
         be made by the Debenture Issuer if a determination is reasonably and
         promptly made (i) by the Regular Trustees by a majority vote of a
         quorum of disinterested Regular Trustees, (ii) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Regular Trustees so directs, by independent legal counsel in a written
         opinion or (iii) the Common Security Holder of the Trust, that, based
         upon the facts known to the Regular Trustees, counsel or the Common
         Security Holder at the time such determination is made, such Company
         Indemnified Person acted in bad faith or in a manner that such person
         did not believe to be in or not opposed to the best interests of the
         Trust, or, with respect to any criminal proceeding, that such Company
         Indemnified Person believed or had reasonable cause to believe his
         conduct was unlawful.  In no event shall any advance be made in
         instances where the Regular Trustees, independent legal counsel or
         Common Security Holder reasonably determine that such person
         deliberately breached his duty to the Trust or its Common or Preferred
         Security Holders.

                 (vi)       The indemnification and advancement of expenses
         provided by, or granted pursuant to, the other paragraphs of this
         Section 10.4(a) shall not be deemed exclusive of any other rights to
         which those seeking indemnification and advancement of expenses may be
         entitled under any agreement, vote of stockholders or disinterested
         directors of the Debenture Issuer or Preferred Security Holders of the
         Trust or otherwise, both as to action in his official capacity and as
         to action in another capacity while holding such office.  All rights
         to indemnification under this Section 10.4(a) shall be deemed to be
         provided by a contract between the Debenture Issuer and each Company
         Indemnified Person who serves in such capacity at any time while this
         Section 10.4(a) is in effect.  Any repeal or modification of this
         Section 10.4(a) shall not affect any rights or obligations then
         existing.

                 (vii)      The Debenture Issuer or the Trust may purchase and
         maintain insurance on behalf of any person who is or was a Company
         Indemnified Person against any liability asserted against him and
         incurred by him in any such capacity, or arising out of his status as
         such, whether or not the Debenture Issuer would have the power to
         indemnify him against such liability under the provisions of this
         Section 10.4(a).

                 (viii)     For purposes of this Section 10.4(a), references to
         "the Trust" shall include, in addition to the resulting or surviving
         entity, any constituent entity (including any constituent of a
         constituent) absorbed in a consolidation or merger, so that any person
         who is or was a director, trustee, officer or employee of such
         constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee or agent
         of another entity, shall stand in the same position under the
         provisions of this Section 10.4(a) with respect to the resulting or
         surviving entity as he would have with respect to such constituent
         entity if its separate existence had continued.

                 (ix)       The indemnification and advancement of expenses
         provided by, or granted pursuant to, this Section 10.4(a) shall,
         unless otherwise provided when authorized or ratified, continue as to
         a person who has ceased to be a Company Indemnified Person and shall
         inure to the benefit of the heirs, executors and administrators of
         such a person.

                 (b)        The Debenture Issuer agrees to indemnify the (i)
Institutional Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the
Institutional Trustee and the Delaware Trustee, and (iv) any officers,
directors, shareholders, members, partners, employees, representatives,
custodians, nominees or agents of the Institutional Trustee and the Delaware
Trustee (each of the Persons in (i) through (iv) being referred to as a
"Fiduciary Indemnified Person") for, and to hold each Fiduciary Indemnified
Person harmless against, any loss, liability or expense incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration or the trust or trusts hereunder, including the
costs and expenses (including reasonable legal fees and expenses) of defending
itself against or investigating any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder.  The
obligation to indemnify as set forth in this Section 10.4(b) shall survive the
satisfaction and discharge of this Declaration.

SECTION 10.5     Outside Businesses.

                 Any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional Trustee may 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
Securities shall have no rights by virtue of this Declaration 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.  No Covered Person, the
Sponsor, the Delaware Trustee, or the Institutional Trustee shall be obligated
to pres-

ent 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 any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional 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 Covered Person, the Delaware
Trustee and the Institutional Trustee may engage or be interested in any
financial or other transaction with the Sponsor or any Affiliate of the
Sponsor, or may act as depositary for, trustee or agent for, or act on any
committee or body of holders of, securities or other obligations of the Sponsor
or its Affiliates.

SECTION 11.1     Fiscal Year.

                 The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

SECTION 11.2     Certain Accounting Matters.

                 (a)        At all times during the existence of the Trust, the
Regular Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail,
each transaction of the Trust.  The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied.  The Trust shall use the accrual method of
accounting for United States federal income tax purposes.  The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year of the Trust by a firm of independent certified public
accountants selected by the Regular Trustees.

                 (b)        The Regular Trustees shall cause to be prepared and
delivered to each of the Holders of Securities, within 90 days after the end of
each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss;

                 (c)        The Regular Trustees shall cause to be duly
prepared and delivered to each of the Holders of Securities, any annual United
States federal income tax information statement, required by the Code,
containing such information with regard to the Securities held by each Holder
as is required by the Code and the Treasury Regulations.  Notwithstanding any
right under the Code to deliver any such statement at a later date, the Regular





                                       46
<PAGE>   52
Trustees shall endeavor to deliver all such statements within 30 days after the
end of each Fiscal Year of the Trust.

                 (d)        The Regular Trustees shall cause to be duly
prepared and filed with the appropriate taxing authority, an annual United
States federal income tax return, on a Form 1041 or such other form required by
United States federal income tax law, and any other annual income tax returns
required to be filed by the Regular Trustees on behalf of the Trust with any
state or local taxing authority.

SECTION 11.3     Banking.

                 The Trust shall maintain one or more bank accounts in the name
and for the sole benefit of the Trust; provided, however, that all payments of
funds in respect of the Debentures held by the Institutional Trustee shall be
made directly to the Institutional Trustee Account and no other funds of the
Trust shall be deposited in the Institutional Trustee Account.  The sole
signatories for such accounts shall be designated by the Regular Trustees;
provided, however, that the Institutional Trustee shall designate the
signatories for the Institutional Trustee Account.

SECTION 11.4     Withholding.

                 The Trust and the Regular Trustees shall comply with all
withholding requirements under United States federal, state and local law.  The
Trust shall request, and the Holders shall provide to the Trust, such forms or
certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably
be requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations.  The Regular Trustees shall file
required forms with applicable jurisdictions and, unless an exemption from
withholding is properly established by a Holder, shall remit amounts withheld
with respect to the Holder to applicable jurisdictions.  To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to distributions or allocations to any Holder, the amount withheld
shall be deemed to be a distribution in the amount of the withholding to the
Holder.  In the event of any claimed over withholding, Holders shall be limited
to an action against the applicable jurisdiction.  If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

SECTION 12.2     Meetings of the Holders of Securities; Action by Written
                 Consent.

                 (a)        Meetings of the Holders of any class of Securities
may be called at any time by the Regular Trustees (or as provided in the terms
of the Securities) to consider and act on any matter on which Holders of such
class of Securities are entitled to act under the terms of this Declaration,
the terms of the Securities or the rules of any stock exchange on which the
Preferred Securities are listed or admitted for trading.  The Regular Trustees
shall call a meeting of the Holders of such class if directed to do so by the
Holders of at least 10% in liquidation amount of such class of Securities.
Such direction shall be given by delivering to the Regular Trustees one or more
calls in a writing stating that the signing Holders of Securities wish to call
a meeting and indicating the general or specific purpose for which the meeting
is to be called.  Any Holders of Securities calling a meeting shall specify in
writing the Security Certificates held by the Holders of Securities exercising
the right to call a meeting and only those Securities specified shall be
counted for purposes of determining whether the required percentage set forth
in the second sentence of this paragraph has been met.

                 (b)        Except to the extent otherwise provided in the
terms of the Securities, the following provisions shall apply to meetings of
Holders of Securities:

                 (i)        notice of any such meeting shall be given to all
         the Holders of Securities having a right to vote thereat at least 7
         days and not more than 60 days before the date of such meeting.
         Whenever a vote, consent or approval of the Holders of Securities is
         permitted or required under this Declaration or the rules of any stock
         exchange on which the Preferred Securities are listed or admitted for
         trading, such vote, consent or approval may be given at a meeting of
         the Holders of Securities.  Any action that may be taken at a meeting
         of the Holders of Securities may be taken without a meeting if a
         consent in writing setting forth the action so taken is signed by the
         Holders of Securities owning not less than the minimum amount of
         Securities in liquidation amount that would be necessary to authorize
         or take such action at a meeting at which all Holders of Securities
         having a right to vote thereon were present and voting.  Prompt notice
         of the taking of action without a meeting shall be given to the
         Holders of Securities entitled to vote who have not consented in
         writing.  The Regular Trustees may specify that any written ballot
         submitted to the Security Holder for the purpose of taking any action
         without a meeting shall be returned to the Trust within the time
         specified by the Regular Trustees;

<PAGE>   56
                 (ii)       each Holder of a Security may authorize any Person
         to act for it by proxy on all matters in which a Holder of Securities
         is entitled to participate, including waiving notice of any meeting,
         or voting or participating at a meeting.  No proxy shall be valid
         after the expiration of 11 months from the date thereof unless
         otherwise provided in the proxy.  Every proxy shall be revocable at
         the pleasure of the Holder of Securities executing it.  Except as
         otherwise provided herein, all matters relating to the giving, voting
         or validity of proxies shall be governed by the General Corporation
         Law of the State of Delaware relating to proxies, and judicial
         interpretations thereunder, as if the Trust were a Delaware
         corporation and the Holders of the Securities were stockholders of a
         Delaware corporation;

                 (iii)      each meeting of the Holders of the Securities shall
         be conducted by the Regular Trustees or by such other Person that the
         Regular Trustees may designate; and

                 (iv)       unless the Business Trust Act, this Declaration,
         the terms of the Securities, the Trust Indenture Act or the listing
         rules of any stock exchange on which the Preferred Securities are then
         listed or trading, otherwise provides, the Regular Trustees, in their
         sole discretion, shall establish all other provisions relating to
         meetings of Holders of Securities, including notice of the time, place
         or purpose of any meeting at which any matter is to be voted on by any
         Holders of Securities, waiver of any such notice, action by consent
         without a meeting, the establishment of a record date, quorum
         requirements, voting in person or by proxy or any other matter with
         respect to the exercise of any such right to vote.

                                    ANNEX I


                                    TERMS OF
                   ___% TRUST ORIGINATED PREFERRED SECURITIES
                    ___% TRUST ORIGINATED COMMON SECURITIES


                 Pursuant to Section 7.1 of the Amended and Restated
Declaration of Trust, dated as of _______, 1996 (as amended from time to time,
the "Declaration"), the designation, rights, privileges, restrictions,
preferences and other terms and provisions of the Preferred Securities and the
Common Securities are set out below (each capitalized term used but not defined
herein has the meaning set forth in the Declaration or, if not defined in such
Declaration, as defined in the Prospectus referred to below):

                 1.       Designation and Number.

                 (a)      Preferred Securities.  [                ] Preferred
Securities of the Trust with an aggregate liquidation amount with respect to
the assets of the Trust of [             ] dollars ($[            ]) and a
liquidation amount with respect to the assets of the Trust of $25 per preferred
security, are hereby designated for the purposes of identification only as
"_____% Trust Originated Preferred SecuritiesSM ('TOPrS'SM)" (the "Preferred
Securities").  The Preferred Security Certificates evidencing the Preferred
Securities shall be substantially in the form of Exhibit A-1 to the
Declaration, with such changes and additions thereto or deletions therefrom as
may be required by ordinary usage, custom or practice or to conform to the
rules of any stock exchange on which the Preferred Securities are listed.

                 (b)      Common Securities.  [               ] Common
Securities of the Trust with an aggregate liquidation amount with respect to
the assets of the Trust of [               ] dollars ($[           ]) and a
liquidation amount with respect to the assets of the Trust of $25 per common
security, are hereby designated for the purposes of identification only as
"______% Trust Originated Common Securities" (the "Common Securities").  The
Common Security Certificates evidencing the Common Securities shall be
substantially in the form of Exhibit A-2 to the Declara- tion, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice.

                 2.       Distributions.

                 (a)      Distributions payable on each Security will be fixed
at a rate per annum of ______% (the "Coupon Rate") of the stated liquidation
amount of $25 per Security, such rate being





                                      I-1
<PAGE>   63
the rate of interest payable on the Debentures to be held by the Institutional
Trustee.  Distributions in arrears for more than one quarter will bear interest
thereon compounded quarterly at the Coupon Rate (to the extent permitted by
applicable law).  The term "Distributions" as used herein includes such cash
distributions and any such interest payable unless otherwise stated.  A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Institutional Trustee and to the extent the
Institutional Trustee has funds available therefor.  The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 90-day quarter.

                 (b)      Distributions on the Securities will be cumulative,
will accrue from ________, 1996, and will be payable quarterly in arrears, on
[March 31, June 30, September 30, and December 31] of each year, commencing on
_______, 1996, except as otherwise described below.  The Debenture Issuer has
the right under the Indenture to defer payments of interest by extending the
interest payment period from time to time on the Debentures for a period not
exceeding 20 consecutive quarters or extend beyond the maturity date of the
Debentures (each an "Extension Period"), during which Extension Period no
interest shall be due and payable on the Debentures, provided that no Extension
Period shall last beyond the date of maturity of the Debentures.  As a
consequence of such deferral, Distributions will also be deferred.  Despite
such deferral, quarterly Distributions will continue to accrue with interest
thereon (to the extent permitted by applicable law) at the Coupon Rate
compounded quarterly during any such Extension Period.  Prior to the
termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters or extend beyond the maturity of the Debentures.  Payments of accrued
Distributions will be payable to Holders as they appear on the books and
records of the Trust on the first record date after the end of the Extension
Period.  Upon the termination of any Extension Period and the payment of all
amounts then due, the Debenture Issuer may commence a new Extension Period,
subject to the above requirements.

                 (c)      Distributions on the Securities will be payable to
the Holders thereof as they appear on the books and records of the Trust on the
relevant record dates.  While the Preferred Securities remain in book-entry
only form, the relevant record dates shall be one Business Day prior to the
relevant payment dates which payment dates correspond to the interest payment
dates on the Debentures.  Subject to any applicable laws and





                                      I-2
<PAGE>   64
regulations and the provisions of the Declaration, each such payment in respect
of the Preferred Securities will be made as described under the heading
"Description of the Preferred Securities -- Book-Entry Only Issuance -- The
Depository Trust Company" in the Prospectus Supplement dated______, 1996, to
the Prospectus dated ______, 1996 (together, the "Prospectus"), of the Trust
included in the Registration Statement on Form S-3 of the Sponsor, the Trust
and certain other business trusts.  The relevant record dates for the Common
Securities shall be the same record date as for the Preferred Securities.  If
the Preferred Securities shall not continue to remain in book-entry only form,
the relevant record dates for the Preferred Securities, shall conform to the
rules of any securities exchange on which the securities are listed and, if
none, shall be selected by the Regular Trustees, which dates shall be at least
one Business Day but less than 60 Business Days before the relevant payment
dates, which payment dates correspond to the interest payment dates on the
Debentures.  Distributions payable on any Securities that are not punctually
paid on any Distribution payment date, as a result of the Debenture Issuer
having failed to make a payment under the Debentures, will cease to be payable
to the Person in whose name such Securities are registered on the relevant
record date, and such defaulted Distribution will instead be payable to the
Person in whose name such Securities are registered on the special record date
or other specified date determined in accordance with the Indenture.  If any
date on which Distributions are payable on the Securities is not a Business
Day, then payment of the Distribution 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 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 such date.

                 (d)      In the event that there is any money or other
property held by or for the Trust that is not accounted for hereunder, such
property shall be distributed Pro Rata (as defined herein) among the Holders of
the Securities.

                 3.       Liquidation Distribution Upon Dissolution.

                 In the event of any voluntary or involuntary dissolution,
winding-up or termination of the Trust, the Holders of the Securities on the
date of the dissolution, winding-up or termination, as the case may be, will be
entitled to receive out of the assets of the Trust available for distribution
to Holders of Securities after satisfaction of liabilities of creditors an
amount equal to the aggregate of the stated liquidation amount of $25 per
Security plus accrued and unpaid Distributions thereon to the date of payment
(such amount being the "Liquidation Distribution"), unless, in connection with
such dissolution, winding-up or termination, Debentures in an aggregate stated
principal





                                      I-3
<PAGE>   65
amount equal to the aggregate stated liquidation amount of such Securities,
with an interest rate equal to the Coupon Rate of, and bearing accrued and
unpaid interest in an amount equal to the accrued and unpaid Distributions on,
such Securities, shall be distributed on a Pro Rata basis to the Holders of the
Securities in exchange for such Securities.

                 If, upon any such dissolution, 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 the Securities shall be paid on a Pro Rata basis.

                 4.       Redemption and Distribution.

                 (a)      Upon the repayment of the Debentures in whole or in
part, whether at maturity or upon redemption (either at the option of the
Debenture Issuer or pursuant to a Tax Event as described below), the proceeds
from such repayment or payment shall be simultaneously applied to redeem
Securities having an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so repaid or redeemed at a redemption price
of $25 per Security plus an amount equal to accrued and unpaid Distributions
thereon at the date of the redemption, payable in cash (the "Redemption
Price").  Holders will be given not less than 30 nor more than 60 days notice
of such redemption.

                 (b)      If fewer than all the outstanding Securities are to
be so redeemed, the Common Securities and the Preferred Securities will be
redeemed Pro Rata and the Preferred Securities to be redeemed will be as
described in Section 4(f)(ii) below.

                 (c)      If, at any time, a Tax Event (as defined below) shall
occur and be continuing the Regular Trustees shall, except in certain limited
circumstances described in this Section 4(c), dissolve the Trust and, after
satisfaction of creditors, cause Debentures held by the Institutional Trustee,
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the Coupon Rate of, and accrued
and unpaid interest equal to accrued and unpaid Distributions on, and having
the same record date for payment as the Securities, to be distributed to the
Holders of the Securities in liquidation of such Holders' interests in the
Trust on a Pro Rata basis, within 90 days following the occurrence of such Tax
Event (the "90 Day Period"); provided, however, that, as a condition of such
dissolution and distribution, the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "No Recognition Opinion"), which opinion may rely on published
revenue rulings of the Internal Revenue Service, to the effect that the Holders
of the Securities will not recognize any gain or loss for United States federal
income tax purposes as a result of the dissolution of the





                                      I-4
<PAGE>   66
Trust and the distribution of Debentures, and provided, further, that, if at
the time there is available to the Trust the opportunity to eliminate, within
the 90 Day Period, the Tax Event by taking some ministerial action, such as
filing a form or making an election, or pursuing some other similar reasonable
measure that has no adverse effect on the Trust, the Debenture Issuer, the
Sponsor or the Holders of the Securities ("Ministerial Action"), the Trust will
pursue such Ministerial Action in lieu of dissolution.

                 If in the event of a Tax Event, (i) after receipt of a Tax
Event Opinion (as defined hereinafter) by the Regular Trustees, the Debenture
Issuer has received an opinion (a "Redemption Tax Opinion") of a nationally
recognized independent tax counsel experienced in such matters that, as a
result of a Tax Event, there is more than an insubstantial risk that the
Debenture Issuer would be precluded from deducting the interest on the
Debentures for United States federal income tax purposes even after the
Debentures were distributed to the Holders of Securities in liquidation of such
Holders' interests in the Trust as described in this Section 4(c), or (ii) the
Regular Trustees shall have been informed by such tax counsel that a No
Recognition Opinion cannot be delivered to the Trust, the Debenture Issuer
shall have the right at any time, upon not less than 30 nor more than 60 days
notice, to redeem the Debentures in whole or in part for cash within 90 days
following the occurrence of such Tax Event, and, following such redemption,
Securities with an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so redeemed shall be redeemed by the Trust
at the Redemption Price on a Pro Rata basis; provided, however, that, if at the
time there is available to the Debenture Issuer or the Trust the opportunity to
eliminate, within such 90 day period, the Special Event by taking some
Ministerial Action, the Trust or the Debenture Issuer will pursue such
Ministerial Action in lieu of redemption.

                 "Tax Event" means that the Regular Trustees shall have
received an opinion of a nationally recognized independent tax counsel
experienced in such matters (a "Dissolution Tax Opinion") to the effect that on
or after the date of the Prospectus Supplement, as a result of (a) any
amendment to, clarification of 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 affecting
taxation, (b) any judicial decision, official adminis- trative pronouncement,
ruling, regulatory procedure, notice or announcement, including any notice or
announcement of intent to adopt such procedures or regulations (an
"Administrative Action") or (c) any amendment to, clarification of, or change
in the official position or the interpretation of such Administrative Action or
judicial decision that differs from the theretofore generally accepted
position, in each case, by any legislative





                                      I-5
<PAGE>   67
body, court, governmental authority or regulatory body, irrespective of the
manner in which such amendment, clarification or change is made known, which
amendment, clarification, or change is effective or such pronouncement or
decision is announced, in each case, on or after, the first date of issuance of
the Securities, there is more than an insubstantial risk that (i) the Trust is
or will be within 90 days of the date thereof, subject to United States federal
income tax with respect to interest accrued or received on the Debentures, (ii)
the Trust is, or will be within 90 days of the date thereof, subject to more
than a de minimis amount of taxes, duties or other governmental charges, or
(iii) interest payable by the Debenture Issuer to the Trust on the Debentures
is not, or within 90 days of the date thereof will not be, deductible, in whole
or in part, by the Debenture Issuer for United States federal income tax
purposes.

                 On and from the date fixed by the Regular Trustees for any
distribution of Debentures and dissolution of the Trust:  (i) the Securities
will no longer be deemed to be outstanding, (ii) The Depository Trust Company
(the "Depository") or its nominee (or any successor Clearing Agency or its
nominee), as the record Holder of the Preferred Securities, will receive a
registered global certificate or certificates representing the Debentures to be
delivered upon such distribution and any certificates representing Securities,
except for certificates representing Preferred Securities held by the
Depository or its nominee (or any successor Clearing Agency or its nominee),
will be deemed to represent beneficial interests in the Debentures having an
aggregate principal amount equal to the aggregate stated liquidation amount of,
with an interest rate identical to the Coupon Rate of, and accrued and unpaid
interest equal to accrued and unpaid Distributions on such Securities until
such certificates are presented to the Debenture Issuer or its agent for
transfer or reissue.

                 (d)      The Trust may not redeem fewer than all the
outstanding Securities unless all accrued and unpaid Distributions have been
paid on all Securities for all quarterly Distribution periods terminating on or
before the date of redemption.

                 (e)      If the Debentures are distributed to holders of the
Securities, pursuant to the terms of the Indenture, the Debenture Issuer will
use its best efforts to have the Debentures listed on the New York Stock
Exchange or on such other exchange as the Preferred Securities were listed
immediately prior to the distribution of the Debentures.

                 (f)      "Redemption or Distribution Procedures."

                 (i)      Notice of any redemption of, or notice of
         distribution of Debentures in exchange for the Securities (a
         "Redemption/Distribution Notice") will be given by the Trust by





                                      I-6
<PAGE>   68
         mail to each Holder of Securities to be redeemed or exchanged not
         fewer than 30 nor more than 60 days before the date fixed for
         redemption or exchange thereof which, in the case of a redemption,
         will be the date fixed for redemption of the Debentures.  For purposes
         of the calculation of the date of redemption or exchange and the dates
         on which notices are given pursuant to this Section 4(f)(i), a
         Redemption/ Distribution Notice shall be deemed to be given on the day
         such notice is first mailed by first-class mail, postage prepaid, to
         Holders of Securities.  Each Redemption/Distribution Notice shall be
         addressed to the Holders of Securities at the address of each such
         Holder appearing in the books and records of the Trust.  No defect in
         the Redemption/Distribution Notice or in the mailing of either thereof
         with respect to any Holder shall affect the validity of the redemption
         or exchange proceedings with respect to any other Holder.

                 (ii)     In the event that fewer than all the outstanding
         Securities are to be redeemed, the Securities to be redeemed shall be
         redeemed Pro Rata from each Holder of Preferred Securities, it being
         understood that, in respect of Preferred Securities registered in the
         name of and held of record by the Depository or its nominee (or any
         successor Clearing Agency or its nominee) or any nominee, the
         distribution of the proceeds of such redemption will be made to each
         Clearing Agency Participant (or Person on whose behalf such nominee
         holds such securities) in accordance with the procedures applied by
         such agency or nominee.

                 (iii)    If Securities are to be redeemed and the Trust gives
         a Redemption/Distribution Notice, which notice may only be issued if
         the Debentures are redeemed as set out in this Section 4 (which notice
         will be irrevocable), then (A) while the Preferred Securities are in
         book-entry only form, with respect to the Preferred Securities, by
         12:00 noon, New York City time, on the redemption date, provided that
         the Debenture Issuer has paid the Institutional Trustee a sufficient
         amount of cash in connection with the related redemption or maturity
         of the Debentures, the Institutional Trustee will deposit irrevocably
         with the Depository or its nominee (or successor Clearing Agency or
         its nominee) funds sufficient to pay the applicable Redemption Price
         with respect to the Preferred Securities and will give the Depository
         irrevocable instructions and authority to pay the Redemption Price to
         the Holders of the Preferred Securities, and (B) with respect to
         Preferred Securities issued in definitive form and Common Securities,
         provided that the Debenture Issuer has paid the Institutional Trustee
         a sufficient amount of cash in connection with the related redemption
         or maturity of the Debentures, the Institutional Trustee will pay the
         relevant Redemption Price to the Holders of





                                      I-7
<PAGE>   69
         such Securities by check mailed to the address of the relevant Holder
         appearing on the books and records of the Trust on the redemption
         date.  If a Redemption/Distribution Notice shall have been given and
         funds deposited as required, if applicable, then immediately prior to
         the close of business on the date of such deposit, or on the
         redemption date, as applicable, distributions will cease to accrue on
         the Securities so called for redemption and all rights of Holders of
         such Securities so called for redemption will cease, except the right
         of the Holders of such Securities to receive the Redemption Price, but
         without interest on such Redemption Price.  Neither the Regular
         Trustees nor the Trust shall be required to register or cause to be
         registered the transfer of any Securities that have been so called for
         redemption.  If any date fixed for redemption of Securities 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 fixed for redemption.  If payment of the Redemption Price in
         respect of any Securities is improperly withheld or refused and not
         paid either by the Institutional Trustee or by the Sponsor as
         guarantor pursuant to the relevant Securities Guarantee, Distributions
         on such Securities will continue to accrue from the original
         redemption date to the actual date of payment, in which case the
         actual payment date will be considered the date fixed for redemption
         for purposes of calculating the Redemption Price.

                 (iv)     Redemption/Distribution Notices shall be sent by the
         Regular Trustees on behalf of the Trust to (A) in respect of the
         Preferred Securities, the Depository or its nominee (or any successor
         Clearing Agency or its nominee) if the Global Certificates have been
         issued or, if Definitive Preferred Security Certificates have been
         issued, to the Holder thereof, and (B) in respect of the Common
         Securities to the Holder thereof.

                 (v)      Subject to the foregoing and applicable law
         (including, without limitation, United States federal securities
         laws), provided the acquiror is not the Holder of the Common
         Securities or the obligor under the Indenture, the Sponsor or any of
         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.

                 5.       Voting Rights - Preferred Securities.

                 (a)      Except as provided under Sections 5(b) and 7 and as
otherwise required by law and the Declaration, the Holders of the Preferred
Securities will have no voting rights.

                 (b)      Subject to the requirements set forth in this
paragraph, the Holders of a majority in aggregate liquidation amount of the
Preferred Securities, voting separately as a class may direct the time, method,
and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including the right to direct the
Institutional Trustee, as holder of the Debentures, to (i) exercise the
remedies available under the Indenture conducting any proceeding for any remedy
available to the Debenture Trustee, or exercising any trust or power conferred
on the Debenture Trustee with respect to the Debentures, (ii) waive any past
default and its consequences that is waivable under Section ___ of the
Indenture, or (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable, provided,
however, that, where a consent under the Indenture would require the consent or
act of the Holders of greater than a majority of the Holders in principal
amount of Debentures affected thereby, (a "Super Majority"), the Institutional
Trustee may only give such consent or take such action at the written direction
of the Holders of at least the proportion in liquidation amount of the
Preferred Securities which the relevant Super Majority represents of the
aggregate principal amount of the Debentures outstanding.  The Institutional
Trustee shall not revoke any action previously authorized or approved by a vote
of the Holders of the Preferred Securities.  Other than with respect to
directing the time, method and place of conducting any remedy available to the
Institutional Trustee or the Debenture Trustee as set forth above, the
Institutional Trustee shall not take any action in accordance with the
directions of the Holders of the Preferred Securities under this paragraph
unless the Institutional Trustee has obtained an opinion of tax counsel to the
effect that for the purposes of United States federal income tax the Trust will
not be classified as other than a grantor trust on account of such action.  If
a Declaration Event of Default has occurred and is continuing and such event is
attributable to the failure of the Debenture Issuer to pay interest or
principal on the Debentures on the date such interest or principal is otherwise
payable (or in the case of redemption, on the redemption date), then a holder
of Preferred Securities may directly institute a proceeding for enforcement of
payment to such Holder of the principal of or interest on the Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder (a "Direct Action") on or after the respective due
date specified in the Debentures.  In connection with such Direct Action, the
rights of





                                      I-9
<PAGE>   71
the holders of the Common Securities Holder will be subrogated to the rights of
such holder of Preferred Securities to the extent of any payment made by the
Issuer to such holder of Preferred Securities in such Direct Action.  Except as
provided in the preceding sentences, the Holders of Preferred Securities will
not be able to exercise directly any other remedy available to the holders of
the Debentures.

                 Any approval or direction of Holders of Preferred Securities
may be given at a separate meeting of Holders of Preferred Securities convened
for such purpose, at a meeting of all of the Holders of Securities in the Trust
or pursuant to written consent.  The Regular Trustees will cause a notice of
any meeting at which Holders of Preferred Securities are entitled to vote, or
of any matter upon which action by written consent of such Holders is to be
taken, to be mailed to each Holder of record of Preferred Securities.  Each
such notice will include a statement setting forth (i) the date of such meeting
or the date by which such action is to be taken, (ii) a description of any
resolution proposed for adoption at such meeting on which such Holders are
entitled to vote or of such matter upon which written consent is sought and
(iii) instructions for the delivery of proxies or consents.

                 No vote or consent of the Holders of the Preferred Securities
will be required for the Trust to redeem and cancel Preferred Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                 Notwithstanding that Holders of Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Preferred Securities that are owned by the Sponsor or any Affiliate of
the Sponsor shall not be entitled to vote or consent and shall, for purposes of
such vote or consent, be treated as if they were not outstanding.

                 6.       Voting Rights - Common Securities.

                 (a)      Except as provided under Sections 7(b), (c) and 8 as
otherwise required by law and the Declaration, the Holders of the Common
Securities will have no voting rights.

                 (b)      The Holders of the Common Securities are entitled, in
accordance with Article V of the Declaration, to vote to appoint, remove or
replace any Trustee or to increase or decrease the number of Trustees.

                 (c)      Subject to Section 2.6 of the Declaration and only
after the Event of Default with respect to the Preferred Securities has been
cured, waived, or otherwise eliminated and subject to the requirements of the
second to last sentence of this paragraph, the Holders of a Majority in
liquidation amount of the





                                      I-10
<PAGE>   72
Common Securities, voting separately as a class, may direct the time, method,
and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including (i) directing the time,
method, place of conducting any proceeding for any remedy available to the
Debenture Trustee, or exercising any trust or power conferred on the Debenture
Trustee with respect to the Debentures, (ii) waive any past default and its
consequences that is waivable under Section ____ of the Indenture, or (iii)
exercise any right to rescind or annul a declaration that the principal of all
the Debentures shall be due and payable, provided that, where a consent or
action under the Indenture would require the consent or act of the Holders of
greater than a majority in principal amount of Debentures affected thereby (a
"Super Majority"), the Institu- tional Trustee may only give such consent or
take such action at the written direction of the Holders of at least the
proportion in liquidation amount of the Common Securities which the relevant
Super Majority represents of the aggregate principal amount of the Debentures
outstanding.  Pursuant to this Section 6(c), the Institutional Trustee shall
not revoke any action previously authorized or approved by a vote of the
Holders of the Preferred Securities.  Other than with respect to directing the
time, method and place of conducting any remedy available to the Institutional
Trustee or the Debenture Trustee as set forth above, the Institutional Trustee
shall not take any action in accordance with the directions of the Holders of
the Common Securities under this paragraph unless the Institutional Trustee has
obtained an opinion of tax counsel to the effect that for the purposes of
United States federal income tax the Trust will not be classified as other than
a grantor trust on account of such action.  If the Institutional Trustee fails
to enforce its rights under the Declaration, any Holder of Common Securities
may institute a legal proceeding directly against any Person to enforce the
Institutional Trustee's rights under the Declaration, without first instituting
a legal proceeding against the Institutional Trustee or any other Person.

                 Any approval or direction of Holders of Common Securities may
be given at a separate meeting of Holders of Common Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent.  The Regular Trustees will cause a notice of any
meeting at which Holders of Common Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Common Securities.  Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such Holders are entitled to vote or of
such matter upon which written consent is





                                      I-11
<PAGE>   73
sought and (iii) instructions for the delivery of proxies or consents.

                 No vote or consent of the Holders of the Common Securities
will be required for the Trust to redeem and cancel Common Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                 7.       Amendments to Declaration and Indenture.

                 (a)      In addition to any requirements under Section 12.1 of
the Declaration, if any proposed amendment to the Declaration provides for, or
the Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 of the Declaration, then the Holders of outstanding Securities
voting together as a single class, will be entitled to vote on such amendment
or proposal (but not on any other 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 Securities, affected thereby,
provided, however, if any amendment or proposal referred to in clause (i) above
would adversely affect only the Preferred Securities or only the Common
Securities, then only the affected 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 a Majority in liquidation amount of such class of
Securities.

                 (b)      In the event the consent of the Institutional Trustee
as the holder of the Debentures is required under the Indenture with respect to
any amendment, modification or termination on the Indenture or the Debentures,
the Institutional Trustee shall request the written direction of the Holders of
the Securities with respect to such amendment, modification or termination and
shall vote with respect to such amendment, modification or termination as
directed by a Majority in liquidation amount of the Securities voting together
as a single class; provided, however, that where a consent under the Indenture
would require the consent of the holders of greater than a majority in
aggregate principal amount of the Debentures (a "Super Majority"), the
Institutional Trustee may only give such consent at the direction of the
Holders of at least the proportion in liquidation amount of the Securities
which the relevant Super Majority represents of the aggregate principal amount
of the Debentures outstanding; provided, further, that the Institutional
Trustee shall not take any action in accordance with the directions of the
Holders of the Securities under this Section 7(b) unless the Institutional
Trustee has obtained an opinion of tax counsel to the effect that for the
purposes of United States federal income





                                      I-12
<PAGE>   74
tax the Trust will not be classified as other than a grantor trust on account
of such action.

                 8.       Pro Rata.

                 A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each
Holder of Securities according to the aggregate liquidation amount of the
Securities held by the relevant Holder in relation to the aggregate liquidation
amount of all Securities outstanding unless, in relation to a payment, an Event
of Default under the Declaration has occurred and is continuing, in which case
any funds available to make such payment shall be paid first to each Holder of
the Preferred Securities pro rata according to the aggregate liquidation amount
of Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Preferred Securities, to
each Holder of Common Securities pro rata according to the aggregate
liquidation amount of Common Securities held by the relevant Holder relative to
the aggregate liquidation amount of all Common Securities outstanding.

                 9.       Ranking.

                 The Preferred Securities rank pari passu and payment thereon
shall be made Pro Rata with the Common Securities except that, where a
Declaration Event of Default occurs and is continuing the rights of Holders of
the Common Securities to payment in respect of Distributions and payments upon
liquidation, redemption and otherwise are subordinated to the rights to payment
of the Holders of the Preferred Securities.

                 10.      Listing.

                 The Regular Trustees shall use their best efforts to cause the
Preferred Securities to be listed for quotation on the New York Stock Exchange,
Inc.

                 11.      Acceptance of Securities Guarantee and Indenture.

                 Each Holder of Preferred Securities and Common Securities, by
the acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.

                 12.      No Preemptive Rights.

                 The Holders of the Securities shall have no preemptive rights
to subscribe for any additional securities.

                 These terms constitute a part of the Declaration.

                 The Sponsor will provide a copy of the Declaration, the
Preferred Securities Guarantee or the Common Securities Guarantee (as may be

<PAGE>   78
                         [FORM OF REVERSE OF SECURITY]

                 Distributions payable on each  Preferred Security will be
fixed at a rate per annum of ______% (the "Coupon Rate") of the stated
liquidation amount of $__ per Preferred Security, such rate being the rate of
interest payable on the Debentures to be held by the Institutional Trustee.
Distributions in arrears for more than one quarter will bear interest thereon
compounded quarterly at the Coupon Rate (to the extent permitted by applicable
law).  The term "Distributions" as used herein includes such cash distributions
and any such interest payable unless otherwise stated.  A Distribution is
payable only to the extent that payments are made in respect of the Debentures
held by the Institutional Trustee and to the extent the Institutional Trustee
has funds available therefor.  The amount of Distributions payable for any
period will be computed for any full quarterly Distribution period on the basis
of a 360- day year of twelve 30-day months, and for any period shorter than a
full quarterly Distribution period for which Distributions are computed,
Distributions will be computed on the basis of the actual number of days
elapsed per 90-day quarter.

                 Except as otherwise described below, distributions on the
Preferred Securities will be cumulative, will accrue from the date of original
issuance and will be payable quarterly in arrears, on [March 31, June 30,
September 30 and December 31] of each year, commencing on ________, 1996, to
[Holders of record fifteen (15) days prior to such payment dates, which payment
dates shall correspond to the interest payment dates on the Debentures.]  The
Debenture Issuer has the right under the Indenture to defer payments of
interest by extending the interest payment period from time to time on the
Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period"), provided that no Extension Period shall last beyond the
date of the maturity of the Debentures and as a consequence of such deferral,
Distributions will also be deferred.  Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period. Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity of
the Debentures.  Payments of accrued Distributions will be payable to Holders
as they appear on the books and records of the Trust on the first record date
after the end of the Extension Period.  Upon the termination of any Extension
Period and the payment of all amounts then due, the Debenture Issuer may
commence a new Extension Period, subject to the above requirements.

                         [FORM OF REVERSE OF SECURITY]

                 Distributions payable on each Common Security will be fixed at
a rate per annum of ______% (the "Coupon Rate") of the stated liquidation
amount of $__ per Common Security, such rate being the rate of interest payable
on the Debentures to be held by the Institutional Trustee.  Distributions in
arrears for more than one quarter will bear interest thereon compounded
quarterly at the Coupon Rate (to the extent permitted by applicable law).  The
term "Distributions" as used herein includes such cash distributions and any
such interest payable unless otherwise stated.  A Distribution is payable only
to the extent that payments are made in respect of the Debentures held by the
Institutional Trustee and to the extent the Institutional Trustee has funds
available therefor.  The amount of Distributions payable for any period will be
computed for any full quarterly Distribution period on the basis of a 360- day
year of twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 90-day quarter.

                 Except as otherwise described below, distributions on the
Common Securities will be cumulative, will accrue from the date of original
issuance and will be payable quarterly in arrears, on [March 31, June 30,
September 30 and December 31] of each year, commencing on ________, 1996, to
Holders of record fifteen (15) days prior to such payment dates, which payment
dates shall correspond to the interest payment dates on the Debentures.  The
Debenture Issuer has the right under the Indenture to defer payments of
interest by extending the interest payment period from time to time on the
Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period"), provided that no Extension Period shall last beyond the
date of the maturity of the Debentures and as a consequence of such deferral,
Distributions will also be deferred.  Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period. Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity
date of the Debentures.  Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the first
record date after the end of the Extension Period.  Upon the termination of any
Extension Period and the payment of all amounts then due, the Debenture Issuer
may commence a new Extension Period, subject to the above requirements.

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

                 All Securities of any one series shall be substantially
identical except as to denomination and except as may otherwise be provided in
or pursuant to such resolution of the Board of Directors or in any such
indenture supplemental hereto.

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

                 SECTION 2.04.  Authentication and Dating.

                 At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities of any series
executed by the Company to the Trustee for authentication, and the Trustee
shall thereupon authenticate and deliver said Securities to or upon the written
order of the Company, signed by its Chairman of the Board of Directors,
President or one of its Vice Presidents and by its Treasurer or any Assistant
Treasurer, without any further action by the Company hereunder.  In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 6.01) shall be fully protected in
relying upon:

                 (1)      a copy of any Board Resolution or Resolutions
                          relating thereto and, if applicable, an appropri- ate
                          record of any action taken pursuant to such
                          resolution, in each case certified by the Secretary
                          or an Assistant Secretary of the Company;

                 (2)      an executed supplemental indenture, if any;

                 (3)      an Officers' Certificate setting forth the form and
                          terms of the Securities as required pursuant to
                          Sections 2.01 and 2.03, respectively; and

                 (4)      an Opinion of Counsel prepared in accordance with
                          Section 13.05 which shall also state:

                          (a)     that the form of such Securities has been
                                  established by or pursuant to a resolution of
                                  the Board of Directors or by a supplemental
                                  indenture as permitted by Section 2.01 in





                                       12
<PAGE>   21
                                  conformity with the provisions of this 
                                  Indenture;

                          (b)     that the terms of such Securities have been
                                  established by or pursuant to a resolution of
                                  the Board of Directors or by a supplemental
                                  indenture as permitted by Section 2.03 in
                                  conformity with the provisions of this
                                  Indenture;

                          (c)     that such Securities, when authenticated and
                                  delivered by the Trustee and issued by the
                                  Company in the manner and subject to any
                                  conditions specified in such Opinion of
                                  Counsel, will constitute valid and legally
                                  binding obligations of the Company;

                          (d)     that all laws and requirements in respect of
                                  the execution and delivery by the Company of
                                  the Securities have been complied with and
                                  that authentication and delivery of the
                                  Securities by the Trustee will not violate
                                  the terms of the Indenture; and

                          (e)     such other matters as the Trustee may 
                                  reasonably request.
    
                 The Trustee shall have the right to decline to authenticate
and deliver any Securities under this Section if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken or if the
Trustee in good faith by its board of directors or trustees, executive
committee, or a trust committee of directors or trustees and/or vice presidents
shall determine that such action would expose the Trustee to personal liability
to existing holders.

                 SECTION 2.05.  Date and Denomination of Securities.

                 The Securities shall be issuable as registered Securities
without coupons and in such denominations as shall be specified as contemplated
by Section 2.03.  In the absence of any such specification with respect to the
Securities of any series, the Securities of such Series shall be issuable in
the denominations of $1,000 and any multiple thereof.  The Securities shall be
numbered, lettered, or otherwise distinguished in such manner or in accordance
with such plans as the officers of the Company executing the same may determine
with the approval of the Trustee as evidenced by the execution and
authentication thereof.

                 Every Security shall be dated the date of its authentication,
shall bear interest, if any, from such date and shall be payable on such dates,
in each case, as contemplated by Section





                                       13
<PAGE>   22
2.03.  The interest installment on any Security that is payable, and is
punctually paid or duly provided for, on any Interest Payment Date for
Securities of that series shall be paid to the Person in whose name said
Security (or one or more Predecessor Securities) is registered at the close of
business on the regular record date for such interest installment.  In the
event that any Security of a particular series or portion thereof is called for
redemption and the redemption date is subsequent to a regular record date with
respect to any Interest Payment Date and prior to such Interest Payment Date,
interest on such Security will be paid upon presentation and surrender of such
Security as provided in Section 3.3.

                 Any interest on any Security that is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date for Security
of the same 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 shall be paid by
the Company, at its election, as provided in clause (1) or clause (2) below:

                 (1)  The Company may make payment of any Defaulted Interest on
         Securities to the Persons in whose names such Securities (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 such 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 not be more than 15 nor 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
         Securityholder at his or her address as it appears in the Security
         Register (as hereinafter defined), not less than 10 days prior to such
         special record date.  Notice of the proposed payment of such Defaulted
         Interest and the special record date therefor having





                                       14
<PAGE>   23
         been mailed as aforesaid, such Defaulted Interest shall be paid to the
         Persons in whose names such Securities (or their respective
         Predecessor Securities) are registered on such special record date and
         shall be no longer payable pursuant to the following clause (2).

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

                 Unless otherwise set forth in a Board Resolution of the
Company or one or more indentures supplemental hereto establishing the terms of
any series of Securities pursuant to Section 2.1 hereof, the term "regular
record date" as used in this Section with respect to a series of Securities
with respect to any Interest Payment Date for such series shall mean either the
fifteenth day of the month immediately preceding the month in which an Interest
Payment Date established for such series pursuant to Section 2.1 hereof shall
occur, if such Interest Payment Date is the first day of a month, or the last
day of the month immediately preceding the month in which an Interest Payment
Date established for such series pursuant to Section 2.1 hereof shall occur, if
such Interest Payment Date is the fifteenth day of a month, whether or not such
date is a Business Day.

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

                 SECTION 2.06.  Execution of Securities.

                 The Securities shall be signed in the name and on behalf of
the Company by the facsimile signature of its Chairman of the Board of
Directors, President or one of its Vice-Presidents and by the facsimile
signature of its Treasurer or one of its Assistant Treasurers, under its
corporate seal which may be affixed thereto or printed, engraved or otherwise
reproduced thereon, by facsimile or otherwise, and which need not be attested.
Only such Securities as shall bear thereon a certificate of authentication
substantially in the form hereinbefore recited, executed by the Trustee or the
Authenticating Agent, shall be entitled to the benefits of this Indenture or be
valid or obligatory for any purpose.  Such certificate by the Trustee or the
Authenticating Agent upon any Security executed by the Company shall be
conclusive evidence that the Security so authenticated





                                       15
<PAGE>   24
has been duly authenticated and delivered hereunder and that the holder is
entitled to the benefits of this Indenture.

                 In case any officer of the Company who shall have signed any
of the Securities shall cease to be such officer before the Securities so
signed shall have been authenticated and delivered by the Trustee or the
Authenticating Agent, or disposed of by the Company, such Securities
nevertheless may be authenticated and delivered or disposed of as though the
person who signed such Securities had not ceased to be such officer of the
Company; and any Security may be signed on behalf of the Company by such
persons as, at the actual date of the execution of such Security, shall be the
proper officers of the Company, although at the date of the execution of this
Indenture any such person was not such an officer.

                 SECTION 2.07.    Exchange and Registration of Transfer of 
                                  Securities.

                 Subject to Section 2.03(12), Securities of any series may be
exchanged for a like aggregate principal amount of Securities of the same
series of other authorized denominations.  Securities to be exchanged may be
surrendered at the principal office of the Trustee or at any office or agency
to be maintained by the Company for such purpose as provided in Section 3.02,
and the Company or the Trustee shall execute and register and the Trustee or
the Authenticating Agent shall authenticate and deliver in exchange therefor
the Security or Securities which the Securityholder making the exchange shall
be entitled to receive.  Upon due presentment for registration of transfer of
any Security of any series at the principal office of the Trustee or at any
office or agency of the Company maintained for such purpose as provided in
Section 3.02, the Company or the Trustee shall execute and register and the
Trustee or the Authenticating Agent shall authenticate and deliver in the name
of the transferee or transferees a new Security or Securities of the same
series for a like aggregate principal amount.  Registration or registration of
transfer of any Security by the Trustee or by any agent of the Company
appointed pursuant to Section 3.02, and delivery of such Security, shall be
deemed to complete the registration or registration of transfer of such
Security.

                 The Company or the Trustee shall keep, at the principal office
of the Trustee, a register for each series of Securities issued hereunder in
which, subject to such reasonable regulations as it may prescribe, the Company
or the Trustee shall register all Securities and shall register the transfer of
all Securities as in this Article Two provided.  Such register shall be in
written form or in any other form capable of being converted into written form
within a reasonable time.





                                       16
<PAGE>   25
                 All Securities presented for registration of transfer or for
exchange or payment shall (if so required by the Company or the Trustee or the
Authenticating Agent) be duly endorsed by, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the Trustee or the Authenticating Agent duly executed by, the holder or his
attorney duly authorized in writing.

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

                 The Company or the Trustee shall not be required to exchange
or register a transfer of (a) any Security for a period of 15 days next
preceding the date of selection of Securities of such series for redemption, or
(b) any Securities of any series selected, called or being called for
redemption in whole or in part, except in the case of any Securities of any
series to be redeemed in part, the portion thereof not so to be redeemed.

                 SECTION 2.08.    Mutilated, Destroyed, Lost or Stolen
                                  Securities.

                 In case any temporary or definitive Security shall become
mutilated or be destroyed, lost or stolen, the Company shall execute, and upon
its request the Trustee shall authenticate and deliver, a new Security of the
same series bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Security, or in lieu of and in substitution for
the Security so destroyed, lost or stolen.  In every case the applicant for a
substituted Security shall furnish to the Company and the Trustee such security
or indemnity as may be required by them to save each of them harmless, and, in
every case of destruction, loss or theft, the applicant shall also furnish to
the Company and the Trustee evidence to their satisfaction of the destruction,
loss or theft of such Security and of the ownership thereof.

                 The Trustee may authenticate any such substituted Security and
deliver the same upon the written request or authorization of any officer of
the Company.  Upon the issuance of any substituted Security, 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 connected
therewith.  In case any Security which has matured or is about to mature or has
been called for redemption in full shall become mutilated or be destroyed, lost
or stolen, the Company may, instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated Security) if the applicant for such payment





                                       17
<PAGE>   26
shall furnish to the Company and the Trustee such security or indemnity as may
be required by them to save each of them harmless and, in case of destruction,
loss or theft, evidence satisfactory to the Company and to the Trustee of the
destruction, loss or theft of such Security and of the ownership thereof.

                 Every substituted Security of any series issued pursuant to
the provisions of this Section 2.08 by virtue of the fact that any such
Security is destroyed, lost or stolen shall constitute an additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be found at any time, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Securities of the same series duly issued hereunder.  All Securities shall be
held and owned upon the express condition that, to the extent permitted by
applicable law, the foregoing provisions are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities and
shall preclude any and all other rights or remedies notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

                 SECTION 2.09.  Temporary Securities.

                 Pending the preparation of definitive Securities of any series
the Company may execute and the Trustee shall authenticate and deliver
temporary Securities (printed or lithographed).  Temporary Securities shall be
issuable in any authorized denomination, and substantially in the form of the
definitive Securities but with such omissions, insertions and variations as may
be appropriate for temporary Securities, all as may be determined by the
Company.  Every such temporary Security shall be executed by the Company and be
authenticated by the Trustee upon the same conditions and in substantially the
same manner, and with the same effect, as the definitive Securities.  Without
unreasonable delay the Company will execute and deliver to the Trustee or the
Authenticating Agent definitive Securities and thereupon any or all temporary
Securities of such series may be surrendered in exchange therefor, at the
principal office of the Trustee or at any office or agency maintained by the
Company for such purpose as provided in Section 3.02, and the Trustee or the
Authenticating Agent shall authenticate and deliver in exchange for such
temporary Securities a like aggregate principal amount of such definitive
Securities.  Such exchange shall be made by the Company at its own expense and
without any charge therefor except that in case of any such exchange involving
a registration of transfer the Company may require payment of a sum sufficient
to cover any tax, fee or other governmental charge that may be imposed in
relation thereto.  Until so exchanged, the temporary Securities of any series
shall in all respects be entitled to the





                                       18
<PAGE>   27
same benefits under this Indenture as definitive Securities of the same series
authenticated and delivered hereunder.

                 SECTION 2.10.  Cancellation of Securities Paid, etc.

                 All Securities surrendered for the purpose of payment,
redemption, exchange or registration of transfer, shall, if surrendered to the
Company or any paying agent, be surrendered to the Trustee and promptly
cancelled by it, or, if surrendered to the Trustee or any Authenticating Agent,
shall be promptly cancelled by it, and no Securities shall be issued in lieu
thereof except as expressly permitted by any of the provisions of this
Indenture.  All Securities cancelled by any Authenticating Agent shall be
delivered to the Trustee.  The Trustee shall destroy cancelled Securities and
shall deliver a certificate of such destruction to the Company.  If the Company
shall acquire any of the Securities, however, such acquisition shall not
operate as a redemption or satisfaction of the indebtedness represented by such
Securities unless and until the same are surrendered to the Trustee for
cancellation.

                 SECTION 2.11.  Global Securities.

                 (a)  If the Company shall establish pursuant to Section 2.03
that the Securities of a particular series are to be issued as a Global
Security, then the Company shall execute and the Trustee shall, in accordance
with Section 2.04, authenticate and deliver, a Global Security that (i) shall
represent, and shall be denominated in an amount equal to the aggregate
principal amount of, all of the outstanding Securities of such series, (ii)
shall be registered in the name of the Depositary or its nominee, (iii) shall
be delivered by the Trustee to the Depositary or pursuant to the Depositary's
instruction and (iv) shall bear a legend substantially to the following effect:
"Except as otherwise provided in Section 2.11 of the Indenture, this Security
may be transferred, in whole but not in part, only to another nominee of the
Depositary or to a successor Depositary or to a nominee of such successor
Depositary."

                 (b)  Notwithstanding the provisions of Section 2.07, the
Global Security of a series may be transferred, in whole but not in part and in
the manner provided in Section 2.07, only to another nominee of the Depositary
for such series, or to a successor Depositary for such series selected or
approved by the Company or to a nominee of such successor Depositary.

                 (c)  If at any time the Depositary for a series of the
Securities notifies the Company that it is unwilling or unable to continue as
Depositary for such series or if at any time the Depositary for such series
shall no longer be registered or in good standing under the Exchange Act, or
other applicable statute or regulation, and a successor Depositary for such
series is not





                                       19
<PAGE>   28
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, as the case may be, this Section 2.11 shall
no longer be applicable to the Securities of such series and the Company will
execute, and subject to Section 2.07, the Trustee will authenticate and deliver
the Securities of such series in definitive registered form without coupons, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security of such series in exchange for such
Global Security.  In addition, the Company may at any time determine that the
Securities of any series shall no longer be represented by a Global Security
and that the provisions of this Section 2.11 shall no longer apply to the
Securities of such series.  In such event the Company will execute and subject
to Section 2.07, the Trustee, upon receipt of an Officers, Certificate
evidencing such determination by the Company, will authenticate and deliver the
Securities of such series in definitive registered form without coupons, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security of such series in exchange for such
Global Security.  Upon the exchange of the Global Security for such Securities
in definitive registered form without coupons, in authorized denominations, the
Global Security shall be cancelled by the Trustee.  Such Securities in
definitive registered form issued in exchange for the Global Security pursuant
to this Section 2.11(c) shall be registered in such names and in such
authorized denominations as the Depositary, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee.  The
Trustee shall deliver such Securities to the Depositary for delivery to the
Persons in whose names such Securities are so registered.

                                  ARTICLE III

                      PARTICULAR COVENANTS OF THE COMPANY.

                 SECTION 3.01.    Payment of Principal, Premium and Interest.

                 The Company covenants and agrees for the benefit of each
series of Securities that it will duly and punctually pay or cause to be paid
the principal of and premium, if any, and interest on each of the Securities of
that series at the place, at the respective times and in the manner provided in
such Securities.  Each installment of interest on the Securities of any series
may be paid by mailing checks for such interest payable to the order of the
holders of Securities entitled thereto as they appear on the registry books of
the Company.

                 SECTION 3.02.  Offices for Notices and Payments, etc.

                 So long as any of the Securities remains outstanding, the
Company will maintain in the Borough of Manhattan, The City of New York, an
office or agency where the Securities of each series may be presented for
payment, an office or agency where the Securities of that Series may be
presented for registration of transfer and for exchange as in this Indenture
provided and an office or agency where notices and demands to or upon the
Company in respect of the Securities of that Series or of this Indenture may be
served.  The Company will give to the Trustee written notice of the location of
any such office or agency and of any change of location thereof.  Until
otherwise designated from time to time by the Company in a notice to the
Trustee, or specified as contemplated by Section 2.03, any such office or
agency for all of the above purposes shall be the office or agency of the
Trustee.  In case the Company shall fail to maintain any such office or agency
in the Borough of Manhattan, The City of New York, or shall fail to give such
notice of the location or of any change in the location thereof, presentations
and demands may be made and notices may be served at the principal office of
the Trustee.

                 In addition to any such office or agency, the Company may from
time to time designate one or more offices or agencies outside the Borough of
Manhattan, The City of New York, where the Securities may be presented for
registration of transfer and for exchange in the manner provided in this
Indenture, and the Company may from time to time rescind such designation, as
the Company may deem desirable or expedient; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain any such office or agency in the Borough of Manhattan,
The City of New York, for the purposes above mentioned.  The Company will give
to the Trustee prompt written notice of any such designation or rescission
thereof.

                 SECTION 3.03.  Appointments to Fill Vacancies in Trustee's 
                                Office.

                 The Company, whenever necessary to avoid or fill a vacancy in
the office of Trustee, will appoint, in the manner provided in Section 6.10, a
Trustee, so that there shall at all times be a Trustee hereunder.

                 SECTION 3.04.  Provision as to Paying Agent.

                 (a)      If the Company shall appoint a paying agent other
                          than the Trustee with respect to the Securities of
                          any series, it will cause such paying agent to
                          execute and deliver to the Trustee an instrument

<PAGE>   30
                          in which such agent shall agree with the Trustee,
                          subject to the provision of this Section 3.04,

                          (1)     that it will hold all sums held by it as such
                                  agent for the payment of the principal of and
                                  premium, if any, or interest, if any, on the
                                  Securities of such series (whether such sums
                                  have been paid to it by the Company or by any
                                  other obligor on the Securities of such
                                  series) in trust for the benefit of the
                                  holders of the Securities of such series; and

                          (2)     that it will give the Trustee notice of any
                                  failure by the Company (or by any other
                                  obligor on the Securities of such series) to
                                  make any payment of the principal of and
                                  premium, if any, or interest, if any, on the
                                  Securities of such series when the same shall
                                  be due and payable.

                 (b)      If the Company shall act as its own paying agent, it
                          will, on or before each due date of the principal of
                          and premium, if any, or interest, if any, on the
                          Securities of any series, set aside, segregate and
                          hold in trust for the benefit of the holders of the
                          Securities of such series a sum sufficient to pay
                          such principal, premium or interest so becoming due
                          and will notify the Trustee of any failure to take
                          such action and of any failure by the Company (or by
                          any other obligor under the Securities of such
                          series) to make any payment of the principal of and
                          premium, if any, or interest, if any, on the
                          Securities of such series when the same shall become
                          due and payable.

                 (c)      Anything in this Section 3.04 to the contrary
                          notwithstanding, the Company may, at any time, for
                          the purpose of obtaining a satisfaction and discharge
                          with respect to one or more or all series of

                          cause to be paid to the Trustee all sums held in
                          trust for any such series by the Trustee or any
                          paying agent hereunder, as required by this Section
                          3.04, such sums to be held by the Trustee upon the
                          trusts herein contained.

                 (d)      Anything in this Section 3.04 to the contrary
                          notwithstanding, the agreement to hold sums in trust
                          as provided in this Section 3.04 is subject to
                          Sections 11.03 and 11.04.

                               Affiliates.

                 If Securities are issued to a Phillips 66 Trust or a trustee
of such trust in connection with the issuance of Trust Securities by such
Phillips 66 Trust and (i) there shall have occurred any event that would
constitute an Event of Default, (ii) the Company shall be in default with

connection with a distribution of Securities, the redemption of all of the
Trust Securities of such Phillips 66 Trust or certain mergers, consolidations
or amalgamations, each as permitted by the Declaration of such Phillips 66
Trust, and (b) to otherwise continue not to be treated as an association

                   SECURITYHOLDERS' LISTS AND REPORTS BY THE
                            COMPANY AND THE TRUSTEE.

                 SECTION 4.01.  Securityholders' Lists.

                 The Company covenants and agrees that it will furnish or cause
to be furnished to the Trustee:

                 (a)      on a monthly basis on each regular record date for
                          each series of Securities, a list, in such form as
                          the Trustee may reasonably require, of the names and
                          addresses of the Securityholders of such series of
                          Securities as of such record date (and on dates to be

                          days prior to the time such list is furnished, except
                          that no such lists need be furnished so long as the
                          Trustee is in possession thereof by reason of its
                          acting as Security registrar for such series.

                 SECTION 4.02.  Preservation and Disclosure of Lists.

                 (a)      The Trustee shall preserve, in as current a form as
                          is reasonably practicable, all information as to the

                          registrar (if so acting) hereunder.  The Trustee may
                          destroy any list furnished to it as provided in
                          Section 4.01 upon receipt of a new list so furnished.

                 (b)      In case 3 or more holders of Securities of any series
                          (hereinafter referred to as "applicants") apply in
                          writing to the Trustee and furnish to the Trustee
                          reasonable proof that each such applicant has owned a
                          Security of such series for a period of at least 6
                          months preceding the date of such application, and

                                  If the Trustee shall elect not to afford such
                          applicants access to such information, the Trustee
                          shall, upon the written request of such applicants,
                          mail to each Securityholder of such series or all
                          Securities, as the case may be, whose name and
                          address appear in the information preserved at the

                          specified in such request with reasonable promptness
                          after a tender to the Trustee of the material to be
                          mailed and of payment, or provision for the payment,
                          of the reasonable expenses of mailing, unless within
                          5 days after such tender, the Trustee shall mail to
                          such applicants and file with the Securities and
                          Exchange Commission, together with a copy of the
                          material to be mailed, a written statement to the
                          effect that, in the opinion of the Trustee, such
                          mailing would be contrary to the best interests of
                          the holders of Securities of such series or all
                          Securities, as the case may be, or would be in
                          violation of applicable law.  Such written statement
                          shall specify the basis of such opinion.  If said
                          Commission, after opportunity for a hearing upon the
                          objections specified in the written statement so
                          filed, shall enter an order refusing to sustain any
                          of such objections or if, after the entry of an order
                          sustaining 1 or more of such objections, said
                          Commission shall find, after notice and opportunity
                          for hearing, that all the objections so sustained
                          have been met and shall enter an order so declaring,
                          the Trustee shall mail copies of such material to all
                          such Securityholders with reasonable promptness after
                          the entry of such order and the renewal of such
                          tender; otherwise the Trustee shall be relieved of
                          any obligation or duty to such applicants respecting
                          their application.

                 (c)      Each and every holder of Securities, by receiving and
                          holding the same, agrees with Company and the Trustee
                          that neither the Company nor the Trustee nor any
                          paying agent shall be held accountable by reason of
                          the disclosure of any such information as to the
                          names and addresses of the holders of Securities in
                          accordance with the provisions of subsection (b) of
                          this Section 4.02, regardless of the source from
                          which such information was derived, and that the
                          Trustee shall not be held accountable by reason of
                          mailing any material pursuant to a request made under
                          said subsection (b).

                          accordance with the terms of any indenture
                          supplemental hereto shall not constitute a default in
                          the payment of principal or premium, if any; or

                 (c)      default in the performance, or breach, of any
                          covenant or warranty of the Company in this Indenture
                          (other than a covenant or warranty a default in whose
                          performance or whose breach is elsewhere in this
                          Section specifically dealt with and other than those
                          set forth exclusively in terms of any particular
                          series of Securities established as contemplated in
                          this Indenture), 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

                          specifying such default or breach and requiring it to
                          be remedied and stating that such notice is a "Notice
                          of Default" hereunder; or

                 (d)      a court having jurisdiction in the premises shall
                          enter a decree or order for relief in respect of the
                          Company in an involuntary case under any applicable
                          bankruptcy, insolvency or other similar law now or
                          hereafter in effect, or appointing a receiver,

                          its affairs and such decree or order shall remain
                          unstayed and in effect for a period of 90 consecutive
                          days; or

                 (e)      the Company shall commence a voluntary case under any
                          applicable bankruptcy, insolvency or other similar
                          law now or hereafter in effect, shall consent to the
                          entry of an order for relief in an involuntary case
                          under any such law, or shall consent to the
                          appointment of or taking possession by a receiver,
                          liquidator, assignee, trustee, custodian,
                          sequestrator (or other similar official) of the
                          Company or of any substantial part of its property,
                          or shall make any general assignment for the benefit
                          of creditors, or shall fail generally to pay its
                          debts as they become due; or

                 (f)              In the event Securities are issued to a
                          Phillips 66 Trust or a trustee of such trust in
                          connection with the issuance of Trust Securities by
                          such Phillips 66 Trust, such Phillips 66 Trust shall
                          have voluntarily or involuntarily dissolved, wound-up
                          its business or otherwise terminated its existence
                          except in connection with (i) the distribution of
                          Securities to holders of Trust Securities in
                          liquidation of their interests in such Phillips 66
                          Trust, (ii) the redemption of all of the outstanding
                          Trust Securities of such Phillips 66 Trust or (iii)
                          certain mergers, consolidations or amalgamations,
                          each as permitted by the Declaration of such Phillips
                          66 Trust.

                 If an Event of Default 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
that series then outstanding hereunder, 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 that series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of that series) of all Securities of that series and the interest accrued
thereon, if any, to be due and payable immediately, and upon any such
declaration the same shall become immediately due and payable.

                 The foregoing provisions, however, are subject to the
condition that if, at any time after the principal (or, if the Securities are
Original Issue 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





                                       31
<PAGE>   40
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 all the Securities of such series (or of all the Securities, as
the case may be) and the principal of and premium, if any, on 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 premium, if any, and, to the extent that payment of such interest
is enforceable under applicable law, on overdue installments of interest, 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 and each predecessor Trustee, 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 if any and all Events of Default under the
Indenture, other than the non-payment of the principal of or premium, if any,
on Securities which shall have become due by acceleration, shall have been
cured, waived or otherwise remedied as provided herein -- then and in every
such case the holders of a majority in aggregate principal amount of the
Securities of such series (or of all the Securities, as the case may be) then
outstanding, by written notice to the Company and to the Trustee, may waive all
defaults with respect to that series (or with respect to all Securities, as the
case may be, in such case, treated as a single class) 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.

                 In case the Trustee shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or
abandoned because of such rescission or annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such
case the Company, the Trustee and the holders of the Securities shall be
restored respectively to their several positions and rights hereunder, and all
rights, remedies and powers of the Company, the Trustee and the holders of the
Securities shall continue as though no such proceeding had been taken.

                 SECTION 5.02.    Payment of Securities on Default; Suit
                                  Therefor.

                 The Company covenants that (a) in case default shall be made
in the payment of any installment of interest upon any of the Securities of any
series as and when the same shall become





                                       32
<PAGE>   41
due and payable, and such default shall have continued for a period of 30 days,
or (b) in case default shall be made in the payment of the principal of or
premium, if any, on any of the Securities of any series as and when the same
shall have become due and payable, whether at maturity of the Securities of
that series or upon 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 that series, the whole amount that then shall
have become due and payable on all such Securities of that series for principal
and premium, if any, or interest, or both, as the case may be, with interest
upon the overdue principal and premium, if any, and (to the extent that payment
of such interest is enforceable under applicable law and, if the Securities are
held by a Phillips 66 Trust or a trustee of such trust, without duplication of
any other amounts paid by Phillips 66 Trust or trustee in respect thereof) upon
the overdue installments of interest at the rate or Yield to Maturity (in the
case of Original Issue Discount Securities) borne by the Securities of that
series; and, in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, including a reasonable compensation
to the Trustee, its agents, attorneys and counsel, and any expenses or
liabilities incurred by the Trustee hereunder other than through 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 actions or proceedings
at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may
enforce any such judgment or final decree against the Company or any other
obligor on such Securities and collect in the manner provided by law out of the
property of the Company or any other obligor on such Securities wherever
situated the moneys adjudged or decreed to be payable.

                 In case there shall be pending proceedings for the bankruptcy
or for the reorganization of the Company or any other obligor on the Securities
of any series under Title 11, United States Code, or any other applicable law,
or in case a receiver or trustee shall have been appointed for the property of
the Company or such other obligor, or in the case of any other similar 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,
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
pursuant to the provisions of this Section 5.02, shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove
a claim or





                                       33
<PAGE>   42
claims for the whole amount of principal and interest (or, if the Securities of
that series are Original Issue Discount Securities such portion of the
principal amount as may be specified in the terms of that series) owing and
unpaid in respect of the Securities of such series and, in case of any judicial
proceedings, to file such proofs of claim and 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 such judicial proceedings
relative to the Company or any other obligor on the Securities of any series,
or to the creditors or property of the Company or such other obligor, unless
prohibited by applicable law and regulations, to vote on behalf of the holders
of the Securities or 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 to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute the same after the deduction
of its charges and expenses; and any receiver, assignee or trustee in
bankruptcy or reorganization is hereby authorized by each of the
Securityholders to make such payments to the Trustee, and, in the event that
the Trustee shall consent to the making of such payments directly to the
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.

                 Nothing herein contained shall be construed to authorize the
Trustee to authorize or consent to 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.

                 All rights of action and of asserting claims under this
Indenture, or under any of the Securities, may be enforced by the Trustee
without the possession of any of the Securities, or the production thereof on
any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment shall be for the ratable benefit of
the holders of the Securities.

                 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, and it shall not be necessary to make any
holders of the Securities parties to any such proceedings.

                 SECTION 5.03. Application of Moneys Collected by Trustee.

                 Any moneys collected by the Trustee shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such moneys, upon presentation of the several Securities in respect of which
moneys have been collected, and stamping thereon the payment, if only partially
paid, and upon surrender thereof if fully paid:

                 First:   To the payment of costs and expenses of collection
applicable to such series and reasonable compensation to the Trustee, its
agents, attorneys and counsel, and of all other expenses and liabilities
incurred, and all advances made, by the Trustee except as a result of its
negligence or bad faith;

                 Second:  To the payment of all Senior Indebtedness of the
Company if and to the extent required by Article Fifteen;

                 Third:   In case the principal of the outstanding Securities
in respect of which moneys have been collected shall not have become due and be
unpaid, to the payment of the amounts then due and unpaid upon Securities of
such series for principal (and premium, if any), and interest on the Securities
of such series, in respect of which or for the benefit of which money has been
collected, ratably, without preference of priority of any kind, according to
the amounts due on such Securities for principal (and premium, if any) and
interest, respectively.

                 SECTION 5.04. Proceedings by Securityholders.

                 No holder of any Security of any series shall have any right
by virtue of or by availing of any provision of this Indenture to institute any
suit, action or proceeding in equity or at law upon or under or with respect to
this Indenture or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless such holder previously shall have given to the
Trustee written notice of an Event of Default and of the continuance thereof
with respect to the Securities of such series specifying such Event of Default,
as hereinbefore provided, and unless also the holders of not less than 25% in
aggregate principal amount of the Securities of that series then outstanding
shall have made written request upon the Trustee to institute such action, suit
or proceeding in its own name as Trustee hereunder and shall have offered to
the Trustee such reasonable





                                       35
<PAGE>   44
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, suit or proceeding, it being understood and intended, and being
expressly covenanted by the taker and holder of every Security with every other
taker and holder and the Trustee, that no one or more holders of Securities of
any series shall have any right in any manner whatever by virtue of or by
availing of any provision of this Indenture to affect, disturb or prejudice the
rights of any other holder of 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.

                 Notwithstanding any other provisions in this Indenture,
however, the right of any holder of any Security to receive payment of the
principal of (premium, if any) and interest, if any, on such Security, on or
after the same shall have become due and payable, or to institute suit for the
enforcement of any such payment, shall not be impaired or affected without the
consent of such holder and by accepting a Security hereunder it is expressly
understood, intended and covenanted by the taker and holder of every Security
of such series with every other such taker and holder and the Trustee, that no
one or more holders of Securities of such series shall have any right in any
manner whatsoever by virtue or by availing of any provision of this Indenture
to affect, disturb or prejudice the rights of the holders of any other 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 series.  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 5.05.  Proceedings by Trustee.

                 In case of an Event of Default hereunder 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 by suit in
equity or by action at law or by proceeding 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.





                                       36

                 SECTION 5.06. Remedies Cumulative and Continuing.

                 Except as otherwise provided in Section 2.08, all powers and
remedies given by this Article Five to the Trustee or to the Securityholders
shall, to the extent permitted by law, be deemed cumulative and not exclusive
of any other powers and remedies available to the Trustee or the holders of the
Securities, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to such series, and no delay or omission of
the Trustee or of any holder of any of the Securities 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 default or an acquiescence therein; and, subject to the provisions of
Section 5.04, every power and remedy given by this Article Five or by law to
the Trustee or to the Securityholders may be exercised from time to time, and
as often as shall be deemed expedient, by the Trustee or by the
Securityholders.

                 SECTION 5.07. Direction of Proceedings and Waiver of
                               Defaults by Majority of Securityholders.

                 The holders of a majority in aggregate principal amount of the
Securities of any or all series affected (voting as one 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; provided, however, 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 shall determine that the
action so directed would be unjustly prejudicial to the holders not taking part
in such direction or if the Trustee being advised by counsel determines that
the action or proceeding so directed may not lawfully be taken or if the
Trustee in good faith by its board of directors or trustees, executive
committee, or a trust committee of directors or trustees and/or Responsible
Officers shall determine that the action or proceedings so directed would
involve the Trustee in personal liability.  Prior to any declaration
accelerating the maturity of any series of the Securities, or of all the
Securities, as the case may be, the holders of a majority in aggregate
principal amount of the Securities of that series at the time outstanding may
on behalf of the holders of all of the Securities of such series waive any past
default or Event of Default including any default estab- lished pursuant to
Section 2.03 and its consequences except a default (a) in the payment of
principal of, premium, if any, or interest on any of the Securities, (b) in
respect of covenants or provisions hereof which cannot be modified or amended
without the consent of the holder of each Security affected, or (c) a default
of the covenants contained in Section 3.06; provided, however,





                                       37
<PAGE>   46
that if the Securities of such series are held by a Phillips 66 Trust or a
trustee of such trust, such waiver or modification to such waiver shall not be
effective until the holders of a majority in liquidation preference of Trust
Securities of the applicable Phillips 66 Trust shall have consented to such
waiver or modification to such waiver; provided further, that if the consent of
the Holder of each outstanding Security is required, such waiver shall not be
effective until each holder of the Trust Securities of the applicable Phillips
66 Trust shall have consented to such waiver.  Upon any such waiver, the
default covered thereby shall be deemed to be cured for all purposes of this
Indenture and 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 the
Company, the Trustee and the holders of the Securities of that series (or of
all Securities, as the case may be) shall be restored to their former positions
and rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon.  Whenever any default or Event of Default hereunder shall have been
waived as permitted by this Section 5.07, said default or Event of Default
shall for all purposes of the Securities of that series (or of all Securities,
as the case may be) and this Indenture be deemed to have been cured and to be
not continuing.

                 SECTION 5.08.  Notice of Defaults.

                 The Trustee shall, within 90 days after the occurrence of a
default with respect to the Securities of any series, mail to all
Securityholders of that series, as the names and addresses of such holders
appear upon the Security register, notice of all defaults with respect to that
series known to the Trustee, unless such defaults shall have been cured before
the giving of such notice (the term "defaults" for the purpose of this Section
5.08 being hereby defined to be the events specified in clauses (a), (b), (c),
(d), (e) and (f) of Section 5.01, not including periods of grace, if any,
provided for therein, and irrespective of the giving of written notice
specified in clause (c) of Section 5.01); and provided that, except in the case
of default in the payment of the principal of, premium, if any, or interest on
any of the Securities of such series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee, or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the
interests of the Securityholders of such series; and provided further , that in
the case of any default of the character specified in Section 5.01(c) no such
notice to Securityholders of such series shall be given until at least 60 days
after the occurrence thereof but shall be given within 90 days after such
occurrence.

                 SECTION 5.09.  Undertaking to Pay 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 5.09 shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Securit- yholder, or
group of Securityholders of any series, holding in the aggregate more than 10%
in principal amount of the Securities of that series outstanding, or to any
suit instituted by any Securityholder for the enforcement of the payment of the
principal of (or premium, if any) or interest on any Security against the
Company on or after the same shall have become due and payable.

                                   ARTICLE VI

                             CONCERNING THE TRUSTEE

                 SECTION 6.01.  Duties and Responsibilities of Trustee.

                 With respect to the holders of any series of Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to securities of that series and after the curing or waiving of all
Events of Default which may have occurred, with respect to securities of that
series, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture.  In case an Event of Default with
respect to the Securities of a series has occurred (which has not been cured or
waived) the Trustee shall exercise such of the rights and powers vested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct
of his own affairs.

                 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

                 (a)      prior to the occurrence of an Event of Default with
                          respect to Securities of a series and after the
                          curing or waiving of all Events of Default

                          with respect to that series which may have occurred

                          (1)     the duties and obligations of the Trustee
                                  with respect to Securities of a series shall
                                  be determined solely by the express
                                  provisions of this Indenture, and the Trustee
                                  shall not be liable except for the
                                  performance of such duties and obligations
                                  with respect to such series 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 the part of
                                  the Trustee, the 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 Trustee and conforming to
                                  the requirements of this Indenture; but, in
                                  the case of any such certificates or opinions
                                  which by any provision 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)      the Trustee shall not be liable for any error of
                          judgment made in good faith by a Responsible Officer
                          or Officers of the Trustee, unless it shall be proved
                          that the Trustee was negligent in ascertaining the
                          pertinent facts; and

                 (c)      the Trustee shall not be liable with respect to any
                          action taken or omitted to be taken by it in good
                          faith, in accordance with the direction of the
                          Securityholders pursuant to Section 5.07, 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.

                 None of the provisions contained in this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if there is reasonable ground for believing
that the repayment of such funds or liability is not reasonably assured to it
under the terms of this Indenture or adequate indemnity against such risk is
not reasonably assured to it.

                 SECTION 6.02.  Reliance on Documents, Opinions, etc.

                 Except as otherwise provided in Section 6.01:

                 (a)      the Trustee may rely and shall be protected in acting
                          or refraining from acting upon any resolution,
                          certificate, statement, instrument, opinion, report,
                          notice, request, consent, order, bond, note,
                          debenture 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)      any request, direction, order or demand of the
                          Company mentioned herein shall be sufficiently
                          evidenced by an Officers' Certificate (unless other
                          evidence in respect thereof be herein spe- cifically
                          prescribed); and any Board Resolution may be
                          evidenced to the Trustee by a copy thereof certified
                          by the Secretary or an Assistant Secretary of the
                          Company;

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

                 (d)      the Trustee shall be under no obligation to exercise
                          any of the rights or powers vested in it by this
                          Indenture at the request, order or direction of any
                          of the Securityholders, pursuant to the provisions of
                          this Indenture, unless such Securityholders shall
                          have offered to the Trustee reasonable security or
                          indemnity against the costs, expenses and liabilities
                          which may be incurred therein or thereby;

                 (e)      the Trustee shall not be liable for any action taken
                          or omitted by it in good faith and believed by it to
                          be authorized or within the discretion or rights or
                          powers conferred upon it by this Indenture; nothing
                          contained herein shall, however, relieve the Trustee
                          of the obligation, upon the occurrence of an Event of
                          Default with respect to a series of the Securities
                          (that has not been cured or waived) to exercise with
                          respect to Securities of that series such of the
                          rights and powers vested in it by this Indenture, and
                          to use the same degree of care and skill in their
                          exercise, as a prudent man would exercise or use
                          under the circumstances in the conduct of his own
                          affairs;

                 (f)      the Trustee shall not be bound to make any
                          investigation into the facts or matters stated in any
                          resolution, certificate, statement, instrument,
                          opinion, report, notice, request, consent, order,
                          approval, bond, debenture, coupon or other paper or
                          document, unless requested in writing to do so by the
                          holders of not less than a majority in principal
                          amount of the outstanding Securities of the series
                          affected thereby; provided, however, that if the
                          payment within a reasonable time to the Trustee of
                          the costs, expenses or liabilities likely to be
                          incurred by it in the making of such investigation
                          is, in the opinion of the Trustee, not reasonably
                          assured to the Trustee by the security afforded to it
                          by the terms of this Inden- ture, the Trustee may
                          require reasonable indemnity against such expense or
                          liability as a condition to so proceeding; 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 (including any
                          Authenticating Agent) or attorneys, and the Trustee
                          shall not be responsible for any misconduct or
                          negligence on the part of any such agent or attorney
                          appointed by it with due care.

                 SECTION 6.03. No Responsibility for Recitals, etc.

                 The recitals contained herein and in the Securities (except in
the certificate of authentication of the Trustee or the Authenticating Agent)
shall be taken as the statements of the Company and the Trustee and the
Authenticating Agent assume no responsibility for the correctness of the same.
The Trustee and the Authenticating Agent make no representations as to the
validity or sufficiency of this Indenture or of the Securities.  The Trustee
and the Authenticating Agent shall not be accountable for the use or
application by the Company of any Securities or the proceeds of any Securities
authenticated and delivered by the Trustee or the Authenticating Agent in
conformity with the provisions of this Indenture.

                 SECTION 6.04. Trustee, Authenticating Agent, Paying Agents,
                               Transfer Agents or Registrar May Own Securities.

                 The Trustee or any Authenticating Agent or any paying agent or
any transfer agent or any Security registrar, in its individual or any other
capacity, may become the owner or pledgee of Securities with the same rights it
would have if it were not Trustee, Authenticating Agent, paying agent, transfer
agent or Security registrar.

                 SECTION 6.05.  Moneys to be Held in Trust.

                 Subject to the provisions of Section 11.04, all moneys
received by the Trustee or any paying agent shall, until used or applied as
herein provided, be held in trust for the purpose for which they were received,
but need not be segregated from other funds except to the extent required by
law.  The Trustee and any paying agent shall be under no liability for interest
on any money received by it hereunder except as otherwise agreed with the
Company.  So long as no Event of Default shall have occurred and be continuing,
all interest allowed on any such moneys shall be paid from time to time upon
the written order of the Company, signed by the Chairman of the Board of
Directors, the President or a Vice President or the Treasurer or an Assistant
Treasurer of the Company.

                 SECTION 6.06.  Compensation and Expenses of Trustee.

                 The Company covenants and agrees to pay to the Trustee from
time to time, and the Trustee shall be entitled to, reasonable compensation
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust), and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ and any amounts paid by the Trustee to any
Authenticating Agent pursuant to Section 6.14) except any such expense,
disbursement or advance as may arise from its negligence or bad faith.  The
Company also covenants to indemnify the Trustee (and its officers, agents,
directors and employees) for, and to hold it harmless against, any loss,
liability or expense incurred without negligence or bad faith on the part of
the Trustee and arising out of or in connection with the acceptance or
administration of this trust, including the costs and expenses of defending
itself against any claim of liability in the premises.  The obligations of the
Company under this Section 6.06 to compensate and indemnify the Trustee and to
pay or reimburse the Trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder.  Such additional indebtedness
shall be secured by a lien prior to that of the Securities upon all property
and funds held or collected by the Trustee as such, except funds held in trust
for the benefit of the holders of particular Securities.

                 SECTION 6.07.  Officers' Certificate as Evidence.

                 Except as otherwise provided in Sections 6.01 and 6.02,
whenever in the administration of the provisions of this Indenture the Trustee
shall deem it necessary or desirable that a matter be proved or established
prior to taking or omitting any





                                       43
<PAGE>   52
action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may, in the absence of negligence or bad faith
on the part of the Trustee, be deemed to be conclusively proved and established
by an Officers' Certificate delivered to the Trustee, and such certificate, in
the absence of negligence or bad faith on the part of the Trustee, shall be
full warrant to the Trustee for any action taken or omitted by it under the
provisions of this Indenture upon the faith thereof.

                 SECTION 6.08.  Conflicting Interest of Trustee.

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

                 SECTION 6.09.  Eligibility of Trustee.

                 The Trustee hereunder shall at all times be a corporation
organized and doing business under the laws of the United States of America or
any State or Territory thereof or of the District of Columbia or a corporation
or other Person permitted to act as trustee by the Commission authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least 50 million U.S. dollars ($50,000,000) and subject to
supervision or examination by Federal, State, Territorial, or District of
Columbia 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 6.09
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.

                 The Company may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Company, serve as
Trustee.

                 In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 6.09, the Trustee shall resign
immediately in the manner and with the effect specified in Section 6.10.

                 SECTION 6.10.  Resignation or Removal of Trustee.

                 (a)      The Trustee, or any trustee or trustees hereafter
                          appointed, may at any time resign with respect to one
                          or more or all series of Securities by giving written
                          notice of such resignation to the Company and by
                          mailing notice thereof to the holders of





                                       44
<PAGE>   53
                          the applicable series of Securities at their
                          addresses as they shall appear on the Security
                          register.  Upon receiving such notice of resignation,
                          the Company shall promptly appoint a successor
                          trustee or trustees with respect to the applicable
                          series by written instrument, in duplicate, executed
                          by order of its Board of Directors, one copy of which
                          instrument shall be delivered to the resigning
                          Trustee and one copy to the successor trustee.  If no
                          successor trustee shall have been so appointed with
                          respect to any series of Securities and have accepted
                          appointment within 30 days after the mailing of such
                          notice of resignation to the affected
                          Securityholders, the resigning Trustee may petition
                          any court of competent jurisdiction for the
                          appointment of a successor trustee, or any
                          Securityholder who has been a bona fide holder of a
                          Security or Securities of the applicable series for
                          at least 6 months may, subject to the provisions of
                          Section 5.09, on behalf of himself and all others
                          similarly situated, petition any such court for the
                          appointment of a successor trustee.  Such court may
                          thereupon, after such notice, if any, as it may deem
                          proper and prescribe, appoint a successor trustee.

                (b)      In case at any time any of the following shall occur --

                          (1)     the Trustee shall fail to comply with the
                                  provisions of subsection (a) of Section 6.08
                                  after written request therefor by the Company
                                  or by any Securityholder who has been a bona
                                  fide holder of a Security or Securities for
                                  at least 6 months, or

                          (2)     the Trustee shall cease to be eligible in
                                  accordance with the provisions of Section
                                  6.09 and shall fail to resign after written
                                  request therefor by the Company or by any
                                  such Securityholder, or

                          (3)     the Trustee shall become incapable of acting,
                                  or shall be adjudged a bankrupt or insolvent,
                                  or a receiver of the Trustee or of its
                                  property shall be appointed, or any public
                                  officer shall take charge or control of the
                                  Trustee or of its property or affairs for the
                                  purpose of rehabilitation, conservation or
                                  liquidation, then, in any such case, the
                                  Company may remove the Trustee and appoint a
                                  successor trustee by written instrument, in

                                  duplicate, executed by order of the Board of
                                  Directors, 1 copy of which instrument shall
                                  be delivered to the Trustee so removed and 1
                                  copy to the successor trustee, or, subject to
                                  the provisions of Section 5.09, any
                                  Securityholder who has been a bona fide
                                  holder of a Security or Securities of the
                                  applicable series for at least 6 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.
                                  Such court may thereupon, after such notice,
                                  if any, as it may deem proper and prescribe,
                                  remove the Trustee and appoint a successor
                                  trustee.

                 (c)      The holders of a majority in aggregate principal
                          amount of the Securities of any series at the time
                          outstanding may at any time remove the Trustee with
                          respect to such series and nominate a successor
                          trustee with respect to the applicable series of
                          Securities or all series, as the case may be, which
                          shall be deemed appointed as successor trustee with
                          respect to the applicable series unless within 10
                          days after such nomination the Company objects
                          thereto, in which case the Trustee so removed or any
                          Securityholder of the applicable series, upon the
                          terms and conditions and otherwise as in subsection
                          (a) of this Section 6.10 provided, may petition any
                          court of competent jurisdiction for an appointment of
                          a successor trustee with respect to such series.

                 (d)      Any resignation or removal of the Trustee and
                          appointment of a successor trustee pursuant to any of
                          the provisions of this Section 6.10 shall become
                          effective upon acceptance of appointment by the
                          successor trustee as provided in Section 6.11.

                 SECTION 6.11.  Acceptance by Successor Trustee.

                 Any successor trustee appointed as provided in Section 6.10
shall execute, acknowledge and deliver to the Company and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the retiring trustee with respect to all or any
applicable series shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations with respect to such series of its predecessor
hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the





                                       46
<PAGE>   55
written request of the Company or of the successor trustee, the trustee ceasing
to act shall, upon payment of any amounts then due it pursuant to the
provisions of Section 6.06, execute and deliver an instrument transferring to
such successor trustee all the rights and powers of the trustee so ceasing to
act and shall duly assign, transfer and deliver to such successor trustee all
property and money held by such retiring trustee thereunder.  Upon request of
any such successor trustee, the Company shall execute any and all instruments
in writing for more fully and certainly vesting in and confirming to such
successor trustee all such rights and powers.  Any trustee ceasing to act
shall, nevertheless, retain a lien upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the provisions of
Section 6.06.

                 If a successor trustee is appointed with respect to the
Securities of one or more (but not all) series, the Company, the retiring
trustee and each successor trustee with respect to the Securities of any
applicable series shall execute and deliver an indenture supplemental hereto
which 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 any series as to which the
predecessor trustee is not retiring shall continue to be vested in the
predecessor trustee, and 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 trustee 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.

                 No successor trustee shall accept appointment as provided in
this Section 6.11 unless at the time of such acceptance such successor trustee
shall be qualified under the provisions of Section 6.08 and eligible under the
provisions of Section 6.09.

                 Upon acceptance of appointment by a successor trustee as
provided in this Section 6.11, the Company shall mail notice of the succession
of such trustee hereunder to the holders of Securities of any applicable series
at their addresses as they shall appear on the Security register.  If the
Company fails to mail such notice within 10 days after the acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

                 SECTION 6.12. Succession by Merger, etc.

                 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 without the execution or filing of any paper or any further act on
the part of any of the parties hereto.

                 In case at the time such successor to the Trustee shall
succeed to the trusts created by this Indenture any of the Securities of any
series shall have been authenticated but not delivered, any such successor to
the Trustee may adopt the certificate of authentication of any predecessor
trustee, and deliver such Securities so authenticated; and in case at that time
any of the Securities of any series shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor trustee; and in all
such cases such certificates shall have the full force which it is anywhere in
the Securities of such series or in this Indenture provided that the
certificate of the Trustee shall have; provided, however, that the right to
adopt the certificate of authentication of any predecessor Trustee or
authenticate Securities of any series in the name of any predecessor Trustee
shall apply only to its successor or successors by merger, conversion or
consolidation.

                 SECTION 6.13. Limitation on Rights of Trustee as a Creditor.

                 The Trustee shall comply with Section 3.11(a) of the Trust
Indenture Act, excluding any creditor relationship described in Section 3.11(b)
of the Trust Indenture Act.  A Trustee who has resigned or been removed shall
be subject to Section 3.11(a) of the Trust Indenture Act to the extent included
therein.

                 SECTION 6.14.  Authenticating Agents.

                 There may be 1 or more Authenticating Agents appointed by the
Trustee upon the request of the Company with power to act on its behalf and
subject to its direction in the authentication and delivery of Securities of
any series issued upon exchange or transfer thereof as fully to all intents and
purposes as though any such Authenticating Agent had been expressly authorized
to authenticate and deliver Securities of such series; provided, that the
Trustee shall have no liability to the Company for any acts or omissions of the
Authenticating Agent with respect to the authentication and delivery of
Securities of any series.  Any such Authenticating Agent shall at all times be
a corporation





                                       48
<PAGE>   57
organized and doing business under the laws of the United States or of any
State or Territory thereof or of the District of Columbia authorized under such
laws to act as Authenticating Agent, having a combined capital and surplus of
at least $5,000,000 and being subject to supervision or examination by Federal,
State, Territorial or District of Columbia authority.  If such corporation
publishes reports of condition at least annually pursuant to law or the
requirements of such authority, then for the purposes of this Section 6.14 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 an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect herein specified in this Section.

                 Any corporation into which any Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate trust business of any Authenticating Agent, shall be the successor of
such Authenticating Agent hereunder, if such successor corporation is otherwise
eligible under this Section 6.14 without the execution or filing of any paper
or any further act on the part of the parties hereto or such Authenticating
Agent.

                 Any Authenticating Agent may at any time resign with respect
to one or more or all series of Securities by giving written notice of
resignation to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of any Authenticating Agent with respect to one or more or
all series of Securities by giving written notice of termination to such
Authenticating Agent and to the Company.  Upon receiving such a notice of
resignation or upon such a termination, or in case at any time any
Authenticating Agent shall cease to be eligible under this Section 6.14, the
Trustee may, and upon the request of the Company shall, promptly appoint a
successor Authenticating Agent with respect to the applicable series eligible
under this Section 6.14, shall give written notice of such appointment to the
Company and shall mail notice of such appointment to all holders of the
applicable series of Securities as the names and addresses of such holders
appear on the Security register.  Any successor Authenticating Agent with
respect to all or any series upon acceptance of its appointment hereunder shall
become vested with all rights, powers, duties and responsibilities with respect
to such series of its predecessor hereunder, with like effect as if originally
named as Authenticating Agent herein.

                 The Trustee agrees to pay to any Authenticating Agent from
time to time reasonable compensation for its services, and the Trustee shall be
entitled to be reimbursed for such payments,





                                       49
<PAGE>   58
subject to Section 6.06.  Any Authenticating Agent shall have no responsibility
or liability for any action taken by it as such in accordance with the
directions of the Trustee.

                                  ARTICLE VII

                         CONCERNING THE SECURITYHOLDERS

                 SECTION 7.01.  Action by Securityholders.

                 Whenever in this Indenture it is provided that the holders of
a specified percentage in aggregate principal amount of the Securities of any
or all series may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action) the fact that at the time of taking any such action the holders of such
specified percentage have joined therein may be evidenced (a) by any instrument
or any number of instruments of similar tenor executed by such Securityholders
in person or by agent or proxy appointed in writing, or (b) by the record of
such holders of Securities voting in favor thereof at any meeting of such
Securityholders duly called and held in accordance with the provisions of
Article Eight, or (c) by a combination of such instrument or instruments and
any such record of such a meeting of such Securityholders.

                 If the Company shall solicit from the Securityholders of any
series any request, demand, authorization, direction, notice, consent, waiver
or other action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Securityholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, 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 action may be given
before or after the record date, but only the Securityholders of record at the
close of business on the record date shall be deemed to be Securityholders for
the purposes of determining whether Securityholders of the requisite proportion
of Outstanding Securities of that series have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other action, and for that purpose the Outstanding Securities of that series
shall be computed as of the record date; provided, however, that no such
authorization, agreement or consent by such Securityholders on the record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Indenture not later than six months after the record date.

                 SECTION 7.02.  Proof of Execution by Securityholders.

                 Subject to the provisions of Section 6.01, 6.02 and 8.05,
proof of the execution of any instrument by a Securityholder or his agent or
proxy shall be sufficient if made in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee.  The ownership of Securities shall be proved by
the Security register or by a certificate of the Security registrar.  The
Trustee may require such additional proof of any matter referred to in this
Section as it shall deem necessary.

                 The record of any Securityholders' meeting shall be proved in
the manner provided in Section 8.06.

                 SECTION 7.03.  Who Are Deemed Absolute Owners.

                 Prior to due presentment for registration of transfer of any
Security, the Company, the Trustee, any Authenticating Agent, any paying agent,
any transfer agent and any Security registrar may deem the person in whose name
such Security shall be registered upon the Security register to be, and may
treat him as, the absolute owner of such Security (whether or not such Security
shall be overdue) for the purpose of receiving payment of or on account of the
principal of, premium, if any, and interest on such Security and for all other
purposes; and neither the Company nor the Trustee nor any Authenticating Agent
nor any paying agent nor any transfer agent nor any Security registrar shall be
affected by any notice to the contrary.  All such payments so made to any
holder for the time being 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.

                 SECTION 7.04.  Securities Owned by Company Deemed Not 
                                Outstanding.

                 In determining whether the holders of the requisite aggregate
principal amount of Securities 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 or by any person directly or indirectly
controlling or controlled by or under direct or indirect common control with
the Company or any other obligor on the Securities shall be disregarded and
deemed not to be outstanding for the purpose of any such determination;
provided that for the purposes 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 out- standing
for the purposes of this Section 7.04 if the pledgee





                                       51
<PAGE>   60
shall establish to the satisfaction of the Trustee the pledgee's right to vote
such Securities and that the pledgee is not the Company or any such other
obligor or person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any such other obligor.
In the case of a dispute as to such right, any decision by the Trustee taken
upon the advice of counsel shall be full protection to the Trustee.

                 SECTION 7.05.    Revocation of Consents; Future Holders Bound.

                 At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 7.01, of the taking of any action by the
holders of the percentage in aggregate principal amount of the Security
specified in this Indenture in connection with such action, any holder of a
Security (or any Security issued in whole or in part in exchange or
substitution therefor) the serial number of which is shown by the evidence to
be included in the Securities the holders of which have consented to such
action may, by filing written notice with the Trustee at its principal office
and upon proof of holding as provided in Section 7.02, revoke such action so
far as concerns such Security (or so far as concerns the principal amount
represented by any exchanged or substituted 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 Security issued in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon such Security or any
Security issued in exchange or substitution therefor.

                                  ARTICLE VIII

                           SECURITYHOLDERS' MEETINGS

                 (a)      to give any notice to the Company or to the Trustee,
                          or to give any directions to the Trustee, or to
                          consent to the waiving of any default hereunder and
                          its consequences, or to take any other action
                          authorized to be taken by Securityholders pursuant to
                          any of the provisions of Article Five;

                 (b)      to remove the Trustee and nominate a successor
                          trustee pursuant to the provisions of Article Six;

<PAGE>   61
                 (c)      to consent to the execution of an indenture or
                          indentures supplemental hereto pursuant to the
                          provisions of Section 9.02; or

                 (d)      to take any other action authorized to be taken by or

                          principal amount of such Securities under any other
                          provision of this Indenture or under applicable law.

of any or all series to take any action specified in Section 8.01, to be held
at such time and at such place in the Borough of Manhattan, The City of New
York, as the Trustee shall determine.  Notice of every meeting of the
Securityholders of any or all 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 mailed to holders of Securities of each series affected at
their addresses as they shall appear on the Securities of each series affected
register.  Such notice shall be mailed not less than 20 nor more than 180 days
prior to the date fixed for the meeting.

                 SECTION 8.03. Call of Meetings by Company or

the Board of Directors, or the holders of at least 10% in aggregate principal
amount of the Securities of any or all series, as the case may be, then
outstanding, shall have requested the Trustee to call a meeting of
Securityholders of any or all series, as the case may be, by written request
setting forth in reasonable detail the action proposed to be taken at the
meeting, and the Trustee shall not have mailed the notice of such meeting
within 20 days after receipt of such request, then the Company or such
Securityholders may determine the time and the place in said Borough of
Manhattan for such meeting and may call such meeting to take any action

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

                 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 Securityholders as provided in Section 8.03, in which case
the Company or the Securityholders 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 majority vote of the
meeting.

                 Subject to the provisions of Section 7.04, at any meeting each
holder of Securities with respect to which such meeting is being held or proxy
therefor shall be entitled to 1 vote for each $1,000 principal amount (in the
case of Original Issue Discount Securities, such principal amount to be
determined as provided in the definition "outstanding") of Securities held or
represented by him; provided, however, that no vote shall be cast or counted at
any meeting in respect of any Security challenged as not outstanding and ruled
by the chairman of the meeting to be not outstanding.  The chairman of the
meeting shall have no right to vote other than by virtue of Securities held by
him or instruments in writing as aforesaid duly designating him as the person
to vote on behalf of other Securityholders.  Any meeting of Securityholders
duly called pursuant to the provisions of Section 8.02 or 8.03 may be adjourned
from time to time by a majority of those present, whether or not constituting a
quorum, and the meeting may be held as so adjourned without further notice.

                 SECTION 8.06.  Voting.

                 The vote upon any resolution submitted to any meeting of
holders of Securities with respect to which such meeting is being held shall be
by written ballots on which shall be subscribed the signatures of such holders
or of their representatives by proxy and the serial number or numbers of the
Securities held or represented by them.  The permanent chairman of the meeting
shall appoint 2 inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who





                                       54
<PAGE>   63
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting.  A record in duplicate
of the proceedings of each meeting of Securityholders 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 1 or more persons having knowledge of the facts setting forth
a copy of the notice of the meeting and showing that said notice was mailed as
provided in Section 8.02.  The record shall show the serial numbers of the
Securities voting in favor of or against any resolution.  The record shall be
signed and verified by the affidavits of the permanent chairman and secretary
of the meeting and 1 of the duplicates shall be delivered to the Company and
the other 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.

                          that such covenants are expressly being included for
                          the benefit of such series) as the Board of Directors

                          provided in this Indenture as herein set forth;
                          provided, however, that in respect of any such

                          supplemental indenture may provide for a particular

                          shorter or longer than that allowed in the case of
                          other defaults) or may provide for an immediate
                          enforcement upon such default or may limit the
                          remedies available to the Trustee upon such default;

                          Securities in coupon form (including Securities
                          registrable as to principal only) and to provide for
                          exchangeability of such Securities with the
                          Securities issued hereunder in fully registered form
                          and to make all appropriate changes for such purpose;

                          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 such other
                          provisions in regard to matters or questions arising
                          under this Indenture; provided that any such action
                          shall not adversely affect the interests of the

                 (h)      to provide for the issuance of and establish the form
                          and terms and conditions of the Securities of any
                          series, to establish the form of any certifications
                          required to be furnished pursuant to the terms of
                          this Indenture or any series of Securities, or to add
                          to the rights of the holders of any series of
                          Securities.

                 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 and assignment of any property thereunder, but
the Trustee shall not be obligated to, but may in its discretion, 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 9.01 may be executed by the Company and the Trustee 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.    Supplemental Indentures with Consent of
                                  Securityholders.

                 With the consent (evidenced as provided in Section 7.01) of
the holders of not less than a majority in aggregate principal amount of the
Securities at the time outstanding of all series affected by such supplemental
indenture (voting as a class), the Company, when authorized by a Board
Resolution, and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act then in effect) for the purpose of adding
any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture or of modifying
in any manner the rights of the holders of the Securities of each series so
affected; provided, however, that no such supplemental indenture shall without
the consent of the holders of each security then outstanding and affected
thereby (i) extend the fixed maturity of any Security of any series, or reduce
the rate or extend the time of payment of interest thereon, or reduce the
principal amount thereof or any premium thereon, or reduce any amount payable
on redemption thereof or make the principal thereof or any interest or premium
thereon payable in any coin or currency other than that provided in the
Securities, or reduce the amount of the principal of an Original Issue Discount
Security that would be due and payable upon an acceleration of the maturity
thereof pursuant to Section 5.01 or the amount thereof provable in bankruptcy
pursuant to Section 5.02, or impair or affect the right of any Securityholder
to institute suit for payment thereof





                                       57
<PAGE>   66
or the right of repayment, if any, at the option of the holder, without the
consent of the holder of each Security so affected, or (ii) reduce the
aforesaid percentage of Securities the holders of which are required to consent
to any such supplemental indenture, without the consent of the holders of each
Security then affected provided, further, that if the Securities of such series
are held by a Phillips 66 Trust or a trustee of such trust, such supplemental
indenture shall not be effective until the holders of a majority in liquidation
preference of Trust Securities of the applicable Trust shall have consented to
such supplemental indenture; provided further, that if the consent of the
Holder of each outstanding Security is required, such supplemental indenture
shall not be effective until each holder of the Trust Securities of the
applicable Phillips 66 Trust shall have consented to such supplemental
indenture.

                 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 Securityholders of such series with respect to such
covenant or provision, shall be deemed not to affect the rights under this
Indenture or the Securityholders of any other series.

                 Upon the request of the Company accompanied by a copy of a
resolution of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Securityholders
as aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.  The Trustee may receive an Opinion of
Counsel as conclusive evidence that any supplemental indenture executed
pursuant to this Article is authorized or permitted by, and conforms to, the
terms of this Article and that it is proper for the Trustee under the
provisions of this Article to join in the execution 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 transmit by mail, first class postage prepaid, a notice, setting
forth in general terms the substance of such supplemental indenture, to the
Securityholders of all series affected thereby as their names and addresses
appear upon the Security register.  Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

<PAGE>   67
                 It shall not be necessary for the consent of the
Securityholders under this Section 9.02 to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such consent
shall approve the substance thereof.

                 SECTION 9.03. Compliance with Trust Indenture Act; Effect of
                               Supplemental Indentures.

                 Any supplemental indenture executed pursuant to the provisions
of this Article Nine shall comply with the Trust Indenture Act, as then in
effect.  Upon the execution of any supplemental indenture pursuant to the
provisions of this Article Nine, this Indenture shall be and be deemed to be
modified and amended in accordance therewith and the respective rights,
limitations of rights, obligations, duties and immunities under this Indenture
of the Trustee, the Company and the holders of Securities of each series
affected thereby shall thereafter be determined, exercised and enforced
hereunder subject in all respects to such modifications and amendments and all
the terms and conditions of any such supplemental indenture shall be and be
deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

                 SECTION 9.04. Notation on Securities.

                 Securities of any series authenticated and delivered after the
execution of any supplemental indenture affecting such series pursuant to the
provisions of this Article Nine may bear a notation in form approved by the
Trustee as to any matter provided for in such supplemental indenture.  If the
Company or the Trustee shall so determine, new Securities of any series so
modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any modification of this Indenture contained in any such
supplemental indenture may be prepared and executed by the Company,
authenticated by the Trustee or the Authenticating Agent and delivered in
exchange for the Securities of any series then outstanding.

                 SECTION 9.05. Evidence of Compliance of Supplemental
                               Indenture to be Furnished Trustee.

                 The Trustee, subject to the provisions of Sections 6.01 and
6.02, may receive an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant hereto
complies with the requirements of this Article Nine.

                 Nothing contained in this Indenture or in any of the
Securities shall prevent any consolidation or merger of the Company with or

the Company, as the case may be, or its successor or successors shall be a
party or parties, or shall prevent any sale, conveyance, transfer or other
disposition of the property of the Company, as the case may be, or its
successor or successors as an entirety, or substantially as an entirety, to any

the terms of each series, according to their tenor and the due and punctual
performance and observance of all the covenants and conditions of this
Indenture with respect to each series or established with respect to such
series to be kept or performed by the Company as the case may be, shall be
expressly assumed, by supplemental indenture (which shall conform to the
provisions of the Trust Indenture Act, as then in effect) satisfactory in form
to the Trustee executed and delivered to the Trustee by the entity formed by
such consolidation, or into which the Company, as the case may be, shall have
been merged, or by the entity which shall have acquired such property.

the Trustee, of the due and punctual payment of the principal of and premium,
if any, and interest on all of the Securities and the due and punctual

Indenture to be performed or observed by the Company, such successor
corporation shall succeed to and be substituted for the Company, with the same
effect as if it had been named herein as the party of the first part, and the
Company thereupon shall be relieved of any further liability or obligation
hereunder or upon the Securities.  Such successor corporation thereupon may
cause to be

signed, and may issue either in its own name or in the name of Phillips
Petroleum Company, any or all of the Securities issuable hereunder which

                          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

                          the case of the Securities of such series being

                          and responsibilities;

                 2.       The Defeasance Agent shall provide verification to
                          the Trustee acknowledging receipt of sufficient money
                          and/or U. S. Government Obligations to meet the
                          applicable conditions set forth in this Section
                          11.05;

                 3.       The Trustee shall determine whether the Company shall
                          be deemed to have been Discharged from its

                 SECTION 13.12. Assignment.

                 The Company will have the right at all times to assign any of
its respective rights or obligations under this Indenture to a direct or
indirect whollyowned Subsidiary of the Company, provided that, in the event of
any such assignment, the Company, as the case may be, will remain liable for
all such obligations.  Subject to the foregoing, the Indenture is binding upon
and inures to the benefit of the parties thereto and their respective
successors and assigns.  This Indenture may not otherwise be assigned by the

                 SECTION 13.13. Acknowledgement of Rights.

                 The Company acknowledges that, with respect to any Securities
held by Phillips 66 Trust or a trustee of such trust, if the Institutional
Trustee of such Trust fails to enforce its rights under this Indenture as the
holder of the series of Securities held as the assets of such Phillips 66 Trust
any holder of Preferred Securities may institute legal proceedings directly
against the Company to enforce such Institutional Trustee's rights under this
Indenture without first instituting any legal proceedings against such
Institutional Trustee or any other person or entity.  Notwithstanding the
foregoing, if an Event of Default has occurred and is continuing and such event
is attributable to the failure of the Company to pay interest or principal on
the applicable series of Securities on the date such interest or principal is
otherwise payable (or in the case of redemption, on the redemption date), the
Company acknowledges that a holder of Preferred Securities may directly
institute a proceeding for enforcement of payment to such holder of the
principal of or interest on the applicable series of Securities having a
principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder on or after the respective due date specified in the
applicable series of Securities.

                             OPTIONAL SINKING FUND

                 SECTION 14.01. Applicability of Article.

                 The provisions of this Article shall be applicable to the
Securities of any series which are redeemable before their maturity or to any
sinking fund for the retirement of Securities of a series except as otherwise
specified as contemplated by Section 2.03 for Securities of such series.

                 SECTION 14.02.   Notice of Redemption; Selection of
                                  Securities.

                 In case the Company shall desire to exercise the right to
redeem all, or, as the case may be, any part of the Securities of any series in
accordance with their terms, it shall fix a date for redemption and shall mail
a notice of such redemption at least 30 and not more than 60 days prior to the
date fixed for redemption to the holders of Securities of such series so to be
redeemed as a whole or in part at their last addresses as the same appear on
the Security register.  Such mailing shall be by first class mail.  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,
failure to give such notice by mail or any defect in the notice to the holder
of any Security of a series designated for redemp- tion as a whole or in part
shall not affect the validity of the proceedings for the redemption of any
other Security of such series.

                 Each such notice of redemption shall specify the date fixed
for redemption, the redemption price at which Securities of such series are to
be redeemed, the place or places of payment, that payment will be made upon
presentation and surrender of such Securities, that interest accrued to the
date fixed for redemption will be paid as specified in said notice, and that on
and after said date interest thereon or on the portions thereof to be redeemed
will cease to accrue.  If less than all the Securities of such series are to be
redeemed the notice of redemption shall specify the numbers of the Securities
of that series to be redeemed.  In case any Security of a series is to be
redeemed in part only, the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the
date fixed for redemption, upon surrender of such Security, a new Security or
Securities of that series in principal amount equal to the unredeemed portion
thereof will be issued.

                 Prior to the redemption date specified in the notice of
redemption given as provided in this Section, the Company will deposit with the
Trustee or with 1 or more paying agents an amount of money sufficient to redeem
on the redemption date all the Securities so called for redemption at the
appropriate redemption price, together with accrued interest to the date fixed
for redemption.

                 If less than all the Securities of a series are to be
redeemed, the Company will give the Trustee notice not less than 60 days prior
to the redemption date as to the aggregate principal amount of Securities of
that series to be redeemed and the Trustee shall select, in such manner as in
its sole discretion it shall deem appropriate and fair, the Securities of that
series or





                                       69
<PAGE>   78
portions thereof (in integral multiples of $1,000, except as otherwise set
forth in the applicable form of Security) to be redeemed.

                 SECTION 14.03. Payment of Securities Called for Redemption.

                 If notice of redemption has been given as provided in Section
14.02 or Section 14.04, the Securities or portions of Securities of the series
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, together with interest accrued to the date fixed for
redemption, and on and after said date (unless the Company shall default in the
payment of such Securities at the redemption price, together with interest
accrued to said date) interest on the Securities or portions of Securities of
any series so called for redemption shall cease to accrue.  On presentation and
surrender of such Securities at a place of payment specified in said notice,
the said Securities or the specified portions thereof shall be paid and
redeemed by the Company at the applicable redemption price, together with
interest accrued thereon to the date fixed for redemption.

                 Upon presentation of any Security of any series 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 such series of authorized denominations, in principal amount
equal to the unredeemed portion of the Security so presented.

                 SECTION 14.04. Mandatory and Optional Sinking Fund.

                 The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any payment in excess of such minimum amount
provided for by the terms of Securities of any series is herein referred to as
an "optional sinking fund payment".  The last date on which any such payment
may be made is herein referred to as a "sinking fund payment date".

                 In lieu of making all or any part of any mandatory sinking
fund payment with respect to any Securities of a series in cash, the Company
may at its option (a) deliver to the Trustee Securities of that series
theretofore purchased by the Company and (b) may apply as a credit Securities
of that series which have been redeemed either at the election of the Company
pursuant to the terms of such Securities or through the application of optional
sinking fund payments pursuant to the next succeeding paragraph, in each case
in satisfaction of all or any part of any mandatory sinking fund payment,
provided that such Securities





                                       70
<PAGE>   79
have not been previously so credited.  Each such Security so delivered or
applied as a credit shall be credited at the sinking fund redemption price for
such Securities and the amount of any mandatory sinking fund shall be reduced
accordingly.  If the Company intends so to deliver or credit such Securities
with respect to any mandatory sinking fund payment it shall deliver to the
Trustee at least 60 days prior to the next succeeding sinking fund payment date
for such series (a) a certificate signed by the Treasurer or an Assistant
Treasurer of the Company specifying the portion of such sinking fund payment,
if any, to be satisfied by payment of cash and the portion of such sinking fund
payment, if any, which is to be satisfied by delivering and crediting such
Securities and (b) any Securities to be so delivered.  All Securities so
delivered to the Trustee shall be cancelled by the Trustee and no Securities
shall be authenticated in lieu thereof.  If the Company fails to deliver such
certificate and Securities at or before the time provided above, the Company
shall not be permitted to satisfy any portion of such mandatory sinking fund
payment by delivery or credit of Securities.

                 At its option the Company may pay into the sinking fund for
the retirement of Securities of any particular series, on or before each
sinking fund payment date for such series, any additional sum in cash as
specified by the terms of such series of Securities.  If the Company intends to
exercise its right to make any such optional sinking fund payment, it shall
deliver to the Trustee at least 60 days prior to the next succeeding sinking
fund payment date for such Series a certificate signed by the Treasurer or an
Assistant Treasurer of the Company stating that the Company intends to exercise
such optional right and specifying the amount which the Company intends to pay
on such sinking fund payment date.  If the Company fails to deliver such
certificate at or before the time provided above, the Company shall not be
permitted to make any optional sinking fund payment with respect to such
sinking fund payment date.  To the extent that such right is not exercised in
any year it shall not be cumulative or carried forward to any subsequent year.

                 If the sinking fund payment or payments (mandatory or
optional) made in cash plus any unused balance of any preceding sinking fund
payments made in cash shall exceed $50,000 (or a lesser sum if the Company
shall so request) with respect to the Securities of any particular series, it
shall be applied by the Trustee or 1 or more paying agents on the next
succeeding sinking fund payment date to the redemption of Securities of such
series at the sinking fund redemption price together with accrued interest to
the date fixed for redemption.  The Trustee shall select, in the manner
provided in Section 14.02, for redemption on such sinking fund payment date a
sufficient principal amount of Securities of such series to absorb said cash,
as nearly as may be, and the Trustee shall, at the expense and in the name of
the Company, thereupon cause notice of redemption of Securities





                                       71
<PAGE>   80
of such series to be given in substantially the manner and with the effect
provided in Sections 14.02 and 14.03 for the redemption of Securities of that
series in part at the option of the Company, except that the notice of
redemption shall also state that the Securities of such series are being
redeemed for the sinking fund.  Any sinking fund moneys not so applied or
allocated by the Trustee or any paying agent to the redemption of Securities of
that series shall be added to the next cash sinking fund payment received by
the Trustee or such paying agent and, together with such payment, shall be
applied in accordance with the provisions of this Section 14.04.  Any and all
sinking fund moneys held by the Trustee or any paying agent on the maturity
date of the Securities of any particular series, and not held for the payment
or redemption of particular Securities of such series, shall be applied by the
Trustee or such paying agent, together with other moneys, if necessary, to be
deposited sufficient for the purpose, to the payment of the principal of the
Securities of that series at maturity.

                 On or before each sinking fund payment date, the Company shall
pay to the Trustee or to 1 or more paying agents in cash a sum equal to all
interest accrued to the date fixed for redemption on Securities to be redeemed
on the next following sinking fund payment date pursuant to this Section.

                 Neither the Trustee nor any paying agent shall redeem any
Securities of a series with sinking fund moneys, and the Trustee shall not mail
any notice of redemption of Securities for such series by operation of the
sinking fund, during the continuance of a default in payment of interest on
such Securities or of any Event of Default (other than an Event of Default
occurring as a consequence of this paragraph), except that if the notice of
redemption of any Securities shall theretofore have been mailed in accordance
with the provisions hereof, the Trustee or any paying agent shall redeem such
Securities if cash sufficient for that purpose shall be deposited with the
Trustee or such paying agent for that purpose in accordance with the terms of
this Article Fourteen.  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 the sinking fund shall, during the
continuance of such default or Event of Default, be held as security for the
payment of all such Securities; provided, however, that in case such Event of
Default or default, shall have been cured or waived as provided herein, such
moneys shall thereafter be applied on the next succeeding sinking fund payment
date on which such moneys may be applied pursuant to the provisions of this
Section 14.04.

                                   ARTICLE XV

                          SUBORDINATION OF SECURITIES

                 SECTION 15.01. Agreement to Subordinate.

                 The Company covenants and agrees, and each holder of
Securities issued hereunder and under any supplemental indenture or by any
resolutions by the Board of Directors ("Additional Provisions") by such
Securityholder's acceptance thereof likewise covenants and agrees, that all
Securities shall be issued subject to the provisions of this Article Fifteen;
and each holder of a Security, whether upon original issue or upon transfer or
assignment thereof, accepts and agrees to be bound by such provisions.

                 The payment by the Company of the principal of, premium, if
any, and interest on all Securities issued hereunder and under any Additional
Provisions shall, to the extent and in the manner hereinafter set forth, be
subordinated and junior in right of payment to the prior payment in full of all
Senior Indebtedness of the Company, whether outstanding at the date of this
Indenture or thereafter incurred.

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

                 SECTION 15.02. Default on Senior Indebtedness.

                 In the event and during the continuation of any default by the
Company in the payment of principal, premium, interest or any other payment due
on any Senior Indebtedness of the Company, as the case may be, or in the event
that the maturity of any Senior Indebtedness of the Company, as the case may
be, has been accelerated because of a default, then, in either case, no payment
shall be made by the Company with respect to the principal (including
redemption and sinking fund payments) of, or premium, if any, or interest on
the Securities.

                 In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee when such payment is prohibited by the
preceding paragraph of this Section 15.02, such payment shall be held in trust
for the benefit of, and shall be paid over or delivered to, the holders of
Senior Indebtedness or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Senior Indebtedness
may have been issued, as their respective interests may appear, but only to the
extent that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

                 SECTION 15.03. Liquidation; Dissolution; Bankruptcy.

                 Upon any payment by the Company or distribution of assets of
the Company of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution or winding-up or liquidation or
reorganization of the Company, whether voluntary or involuntary or in
bankruptcy, insolvency, receivership or other proceedings, all amounts due upon
all Senior Indebtedness of the Company shall first be paid in full, or payment
thereof provided for in money in accordance with its terms, before any payment
is made by the Company on account of the principal (and premium, if any) or
interest on the Securities; and upon any such dissolution or winding-up or
liquidation or reorganization, any payment by the Company, or distribution of
assets of the Company of any kind or character, whether in cash, property or
securities, to which the Securityholders or the Trustee would be entitled to
receive from the Company, except for the provisions of this Article Fifteen,
shall be paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or distribution,
or by the Securityholders or by the Trustee under the Indenture if received by
them or it, directly to the holders of Senior Indebtedness of the Company (pro
rata to such holders on the basis of the respective amounts of Senior
Indebtedness held by such holders, as calculated by the Company) or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, as their respective interests may appear, to the extent
necessary to pay such Senior Indebtedness in full, in money or money's worth,
after giving effect to any concurrent payment or distribution to or for the
holders of such Senior Indebtedness, before any payment or distribution is made
to the Securityholders or to the Trustee.

                 In the event that, notwithstanding the foregoing, any payment
or distribution of assets of the Company of any kind or character, whether in
cash, property or securities, prohibited by the foregoing, shall be received by
the Trustee before all Senior Indebtedness of the Company is paid in full, or
provision is made for such payment in money in accordance with its terms, such
payment or distribution shall be held in trust for the benefit of and shall be
paid over or delivered to the holders of such Senior Indebtedness or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, and their respective interests may appear, as calculated
by the Company, for application to the payment of all Senior Indebtedness of
the Company, as the case may be, remaining unpaid to the extent necessary to
pay such Senior Indebtedness in full in money in accordance with its terms,
after giving effect to any concurrent payment or distribution to or for the
benefit of the holders of such Senior Indebtedness.

                 For purposes of this Article Fifteen, the words "cash,
property or securities" shall not be deemed to include shares of stock of the
Company as reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated at least to the extent provided in this
Article Fifteen with respect to the Securities to the payment of all Senior
Indebtedness of the Company, as the case may be, that may at the time be
outstanding, provided that (i) such Senior Indebtedness is assumed by the new
corporation, if any, resulting from any such reorganization or readjustment,
and (ii) the rights of the holders of such Senior Indebtedness are not, without
the consent of such holders, altered by such reorganization or readjustment.
The consolidation of the Company with, or the merger of the Company into,
another corporation or the liquidation or dissolution of the Company following
the conveyance or transfer of its property as an entirety, or substantially as
an entirety, to another corporation upon the terms and conditions provided for
in Article Ten of this Indenture shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 15.03 if such
other corporation shall, as a part of such consolidation, merger, conveyance or
transfer, comply with the conditions stated in Article Ten of this Indenture.
Nothing in Section 15.02 or in this Section 15.03 shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 6.05 of this Indenture.

                 SECTION 15.04. Subrogation.

                 Subject to the payment in full of all Senior Indebtedness of
the Company, the rights of the Securityholders shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company, as the case may
be, applicable to such Senior Indebtedness until the principal of (and premium,
if any) and interest on the Securities shall be paid in full; and, for the
purposes of such subrogation, no payments or distributions to the holders of
such Senior Indebtedness of any cash, property or securities to which the
Securityholders or the Trustee would be entitled except for the provisions of
this Article Fifteen, and no payment over pursuant to the provisions of this
Article Fifteen to or for the benefit of the holders of such Senior
Indebtedness by Securityholders or the Trustee, shall, as between the Company,
its creditors other than holders of Senior Indebtedness of the Company, and the
holders of the Securities, be deemed to be a payment by the Company to or on
account of such Senior Indebtedness.  It is understood that the provisions of
this Article Fifteen are and are intended solely for the purposes of defining
the relative rights of the holders of the Securities, on the one hand, and the
holders of such Senior Indebtedness on the other hand.





                                       75
<PAGE>   84
                 Nothing contained in this Article Fifteen or elsewhere in this
Indenture, any Additional Provisions or in the Securities is intended to or
shall impair, as between the Company, its creditors other than the holders of
Senior Indebtedness of the Company, and the holders of the Securities, the
obligation of the Company, which is absolute and unconditional, to pay to the
holders of the Securities the principal of (and premium, if any) and interest
on the Securities as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative
rights of the holders of the Securities and creditors of the Company, as the
case may be, other than the holders of Senior Indebtedness of the Company, as
the case may be, nor shall anything herein or therein prevent the Trustee or
the holder of any Security from exercising all remedies otherwise permitted by
applicable law upon default under the Indenture, subject to the rights, if any,
under this Article Fifteen of the holders of such Senior Indebtedness in
respect of cash, property or securities of the Company, as the case may be,
received upon the exercise of any such remedy.

                 Upon any payment or distribution of assets of the Company
referred to in this Article Fifteen, the Trustee, subject to the provisions of
Article Six of this Indenture, and the Securityholders shall be entitled to
conclusively rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of the receiver,
trustee in bankruptcy, liquidation trustee, agent or other Person making such
payment or distribution, delivered to the Trustee or to the Securityholders,
for the purposes of ascertaining the Persons entitled to participate in such
distribution, the holders of Senior Indebtedness and other indebtedness of the
Company, as the case may be, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article Fifteen.

                 SECTION 15.05. Trustee to Effectuate Subordination.

                 Each Securityholder by such Securityholder's acceptance
thereof authorizes and directs the Trustee on such Securityholder's behalf to
take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article Fifteen and appoints the Trustee such
Securityholder's attorney-in-fact for any and all such purposes.

                 SECTION 15.06. Notice by the Company.

                 The Company shall give prompt written notice to a Responsible
Officer of the Trustee of any fact known to the Company that would prohibit the
making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article Fifteen.  Notwithstanding
the provi-





                                       76
<PAGE>   85
sions of this Article Fifteen or any other provision of this Indenture or any
Additional Provisions, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies
to or by the Trustee in respect of the Securities pursuant to the provisions of
this Article Fifteen, unless and until a Responsible Officer of the Trustee
shall have received written notice thereof from the Company or a holder or
holders of Senior Indebtedness or from any trustee therefor; and before the
receipt of any such written notice, the Trustee, subject to the provisions of
Article Six of this Indenture, shall be entitled in all respects to assume that
no such facts exist; provided, however, that if the Trustee shall not have
received the notice provided for in this Section 15.06 at least two Business
Days prior to the date upon which by the terms hereof any money may become
payable for any purpose (including, without limitation, the payment of the
principal of (or premium, if any) or interest on any Debenture), then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such money and to apply the same to the purposes
for which they were received, and shall not be affected by any notice to the
contrary that may be received by it within two Business Days prior to such
date.

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

                 SECTION 15.07.   Rights of the Trustee; Holders of Senior 
                                  Indebtedness.

                 The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article Fifteen in respect of any Senior
Indebtedness at any time held by it, to the same extent as any other holder of
Senior Indebtedness, and





                                       77
<PAGE>   86
nothing in this Indenture or any Additional Provisions shall deprive the
Trustee of any of its rights as such holder.

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

                 SECTION 15.08.   Subordination May Not Be Impaired.

                 No right of any present or future holder of any Senior
Indebtedness of the Company 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, as the case may be, or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Company,
as the case may be, with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof that any such holder may have or otherwise
be charged with.

                 Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness of the Company may, at any time
and from time to time, without the consent of or notice to the Trustee or the
Securityholders, without incurring responsibility to the Securityholders and
without impairing or releasing the subordination provided in this Article
Fifteen or the obligations hereunder of the holders of the Securities to the
holders of such Senior Indebtedness, do any one or more of the following:  (i)
change the manner, place or terms of payment or extend the time of payment of,
or renew or alter, such Senior Indebtedness, or otherwise amend or supplement
in any manner such Senior Indebtedness or any instrument evidencing the same or
any agreement under which such Senior Indebtedness is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Senior Indebtedness; (iii) release any Person liable in
any manner for the collection of such Senior Indebtedness; and (iv) exercise or
refrain from exercising any rights against the Company, as the case may be, and
any other Person.

SECTION 2.4.     Global Debenture.

                 (a)  In connection with a Dissolution Event,

                          (i)     the Debentures in certificated form may be
         presented to the Trustee by the Institutional Trustee in exchange for
         a global Debenture in an aggregate principal amount equal to the
         aggregate principal amount of all outstanding Debentures (a "Global
         Debenture"), to be registered in the name of the Depositary, or its
         nominee, and delivered by the Trustee to the Depositary for crediting
         to the accounts of its participants pursuant to the instructions of
         the Regular Trustees.  The Company upon any such presenta- tion shall
         execute a Global Debenture in such aggregate principal amount and
         deliver the same to the Trustee for authentication and delivery in
         accordance with the Indenture and this First Supplemental Indenture.
         Payments on the Debentures issued as a Global Debenture will be made
         to the Depositary; and

                          (ii)    if any Preferred Securities are held in non
         book-entry certificated form, the Debentures in certificated form may
         be presented to the Trustee by the Institutional Trustee and any
         Preferred Security Certificate which represents Preferred Securities
         other than Preferred Securities held by the Clearing Agency or its
         nominee ("Non Book-Entry Preferred Securities") will be deemed to
         represent beneficial interests in Debentures presented to the Trustee
         by the Institutional Trustee having an aggregate principal amount
         equal to the aggregate liquidation amount of the Non Book-Entry
         Preferred Securities until such Preferred Security Certificates are
         presented to the Security Registrar for transfer or reissuance at
         which time such Preferred Security Certificates will be cancelled and
         a Debenture, registered in the name of the holder of the Preferred
         Security Certificate or the transferee of the holder of such Preferred
         Security Certificate, as the case may be, with an aggregate principal
         amount equal to the aggregate liquidation amount of the Preferred
         Security Certificate cancelled, will be executed by the Company and
         delivered to the Trustee for authentication and delivery in accordance
         with the Indenture and this First Supplemental Indenture.  On issue of
         such Debentures, Debentures with an equivalent aggregate principal
         amount that were presented by the Institutional Trustee to the Trustee
         will be deemed to have been cancelled.

                 (b)      A Global Debenture may be transferred, in whole but
not in part, only to another nominee of the Depositary, or to a successor
Depositary selected or approved by the Company or to a nominee of such
successor Depositary.

<PAGE>   8
                 (c)      If at any time the Depositary notifies the Company
that it is unwilling or unable to continue as Depositary or if at any time the
Depositary for such series shall no longer be registered or in good standing
under the Securities Exchange Act of 1934, as amended, or other applicable
statute or regulation, and a successor Depositary for such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, as the case may be, the Company will
execute, and, subject to Article II of the Indenture, the Trustee, upon written
notice from the Company, will authenticate and deliver the Debentures in
definitive registered form without coupons, in authorized denominations, and in
an aggregate principal amount equal to the principal amount of the Global
Debenture in exchange for such Global Debenture.  In addition, the Company may
at any time determine that the Debentures shall no longer be represented by a
Global Debenture.  In such event the Company will execute, and subject to
Section 2.07 of the Indenture, the Trustee, upon receipt of an Officers
Certificate evidencing such determination by the Company, will authenticate and
deliver the Debentures in definitive registered form without coupons, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Debenture in exchange for such Global Debenture.
Upon the exchange of the Global Debenture for such Debentures in definitive
registered form without coupons, in authorized denominations, the Global
Debenture shall be cancelled by the Trustee.  Such Debentures in definitive
registered form issued in exchange for the Global Debenture shall be registered
in such names and in such authorized denominations as the Depositary, pursuant
to instructions from its direct or indirect participants or other- wise, shall
instruct the Trustee.  The Trustee shall deliver such Securities to the
Depositary for delivery to the Persons in whose names such Securities are so
registered.

SECTION 2.5.     Interest.

                 (a)      Each Debenture will bear interest at the rate of ___%
per annum (the "Coupon Rate") from the original date of issuance until the
principal thereof becomes due and payable, and on any overdue principal and (to
the extent that payment of such interest is enforceable under applicable law)
on any overdue installment of interest at the Coupon Rate, compounded
quarterly, payable (subject to the provisions of Article Four) quarterly in
arrears on [March 31, June 30, September 30 and December 31] of each year
(each, an "Interest Payment Date," commencing on _________ __, 1996), to the
Person in whose name such Debenture or any predecessor Debenture is registered,
at the close of business on the regular record date for such interest
installment, which, in respect of any Debentures of which the Institutional
Trustee is the Holder of a Global Debenture, shall be the close of business on
the Business Day next preceding that Interest Payment Date.  Notwithstanding
the foregoing sentence, if the





                                       5
<PAGE>   9
Preferred Securities are no longer in book-entry only form, except if the
Debentures are held by the Institutional Trustee, the Debentures are not
represented by a Global Debenture, the Company may select a regular record date
for such interest installment which shall be any date at least one Business Day
before an Interest Payment Date.

                 (b)      The amount of interest payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months.  Except as
provided in the following sentence, the amount of interest payable for any
period shorter than a full quarterly period for which interest is computed,
will be computed on the basis of the actual number of days elapsed in such a
30-day period. In the event that any date on which interest is payable on the
Debentures is not a Business Day, then payment of interest payable on such date
will be made on the 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 such date.

                 (c)      If, at any time while the Institutional Trustee is
the Holder of any Debentures, the Trust or the Institutional Trustee is
required to pay any taxes, duties, assessments or governmental charges of
whatever nature (other than withholding taxes) imposed by the United States, or
any other taxing authority, then, in any case, the Company will pay as
additional interest ("Additional Interest") on the Debentures held by the
Institutional Trustee, such additional amounts as shall be required so that the
net amounts received and retained by the Trust and the Institutional Trustee
after paying such taxes, duties, assessments or other governmental charges will
be equal to the amounts the Trust and the Institutional Trustee would have
received had no such taxes, duties, assessments or other government charges
been imposed.

                          REDEMPTION OF THE DEBENTURES

SECTION 3.1.     Special Event Redemption.

                 If a Tax Event has occurred and is continuing and:

                 (a)      the Company has received a Redemption Tax Opinion; or

                 (b)      after receiving a Dissolution Tax Opinion, the
         Regular Trustees shall have been informed by tax counsel





                                       6
<PAGE>   10
         rendering the Dissolution Tax Opinion that a No Recognition Opinion
         cannot be delivered to the Trust,

then, notwithstanding Section 3.2(a) but subject to Section 3.2(b), the Company
shall have the right upon not less than 30 days nor more than 60 days notice to
the Holders of the Debentures to redeem the Debentures, in whole or in part,
for cash within 90 days following the occurrence of such Tax Event (the "90 Day
Period") at a redemption price equal to 100% of the principal amount to be
redeemed plus any accrued and unpaid interest thereon to the date of such
redemption (the "Redemption Price"), provided that if at the time there is
available to the Company the opportunity to eliminate, within the 90 Day
Period, the Tax Event by taking some ministerial action ("Ministerial Action"),
such as filing a form or making an election, or pursuing some other similar
reasonable measure which has no adverse effect on the Company, the Trust or the
Holders of the Trust Securities issued by the Trust, the Company shall pursue
such Ministerial Action in lieu of redemption, and, provided, further, that the
Company shall have no right to redeem the Debentures while the Trust is
pursuing any Ministerial Action pursuant to its obligations under the
Declaration.  The Redemption Price shall be paid prior to 12:00 noon, New York
time, on the date of such redemption or such earlier time as the Company
determines, provided that the Company shall deposit with the Trustee an amount
sufficient to pay the Redemption Price by 10:00 a.m., New York time, on the
date such Redemption Price is to be paid.

SECTION 3.2.     Optional Redemption by Company.

                 (a)      Subject to the provisions of Section 3.2(b) and to
the provisions of Article XIV of the Indenture, except as otherwise may be
specified in this First Supplemental Indenture, the Company shall have the
right to redeem the Debentures, in whole or in part, from time to time, on or
after _________, 2001, at a redemption price equal to 100% of the principal
amount to be redeemed plus any accrued and unpaid interest thereon to the date
of such redemption (the "Optional Redemption Price").  Any redemption pursuant
to this paragraph will be made upon not less than 30 days nor more than 60 days
notice to the Holder of the Debentures, at the Optional Redemption Price.  If
the Debentures are only partially redeemed pursuant to this Section 3.2, the
Debentures will be redeemed pro rata or by lot or by any other method utilized
by the Trustee; provided, that if at the time of redemption the Debentures are
registered as a Global Debenture, the Depositary shall determine, in accordance
with its procedures, the principal amount of such Debentures held by each
Holder of Debenture to be redeemed.  The Optional Redemption Price shall be
paid prior to 12:00 noon, New York time, on the date of such redemption or at
such earlier time as the Company determines provided that the Company shall
deposit with the Trustee an amount sufficient to pay the Optional Redemption
Price

by 10:00 a.m., New York time, on the date such Optional Redemption Price is to
be paid.

                 (b)      If a partial redemption of the Debentures would
result in the delisting of the Preferred Securities issued by the Trust from
any national securities exchange or other organization on which the Preferred
Securities are then listed, the Company shall not be permitted to effect such
partial redemption and may only redeem the Debentures in whole.

SECTION 3.3.     No Sinking Fund.

                 The Debentures are not entitled to the benefit of any sinking
fund.


                                   ARTICLE IV
                      EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 4.1.     Extension of Interest Payment Period.

                 The Company shall have the right, at any time and from time to
time during the term of the Debentures, to defer payments of interest by
extending the interest payment period of such Debentures for a period not
exceeding 20 consecutive quarters (the "Extended Interest Payment Period"),
during which Extended Interest Payment Period no interest shall be due and
payable; provided that no Extended Interest Payment Period may extend beyond
the Maturity Date.  To the extent permitted by applicable law, interest, the
payment of which has been deferred because of the extension of the interest
payment period pursuant to this Section 4.1, will bear interest thereon at the
Coupon Rate compounded quarterly for each quarter of the Extended Interest
Payment Period ("Compounded Interest").  At the end of the Extended Interest
Payment Period, the Company shall pay all interest accrued and unpaid on the
Debentures, including any Additional Interest and Compounded Interest
(together, "Deferred Interest") that shall be payable to the Holders of the
Debentures in whose names the Debentures are registered in the Security
Register on the first record date after the end of the Extended Interest
Payment Period.  Before the termination of any Extended Interest Payment
Period, the Company may further extend such period, provided that such period
together with all such further extensions thereof shall not exceed 20
consecutive quarters, or extend beyond the maturity date of the Debentures.
Upon the termination of any Extended Interest Payment Period and upon the
payment of all Deferred Interest then due, the Company may commence a new
Extended Interest Payment Period, subject to the foregoing requirements.  No
interest shall be due and payable during an Extended Interest Payment Period,
except at the end thereof, but the Company may prepay at any time all or any





                                       8
<PAGE>   12
portion of the interest accrued during an Extended Interest Payment Period.

SECTION 4.2.     Notice of Extension.

                 (a)      If the Institutional Trustee is the only registered
Holder of the Debentures at the time the Company selects an Extended Interest
Payment Period, the Company shall give written notice to the Regular Trustees,
the Institutional Trustee and the Trustee of its selection of such Extended
Interest Payment Period one Business Day before the earlier of (i) the next
succeeding date on which Distributions on the Trust Securities issued by the
Trust are payable, or (ii) the date the Trust is required to give notice of the
record date, or the date such Distributions are payable, to the New York Stock
Exchange or other applicable self-regulatory organization or to holders of the
Preferred Securities issued by the Trust, but in any event at least one
Business Day before such record date.

                 (b)      If the Institutional Trustee is not the only Holder
of the Debentures at the time the Company selects an Extended Interest Payment
Period, the Company shall give the Holders of the Debentures and the Trustee
written notice of its selection of such Extended Interest Payment Period at
least 10 Business Days before the earlier of (i) the next succeeding Interest
Payment Date, or (ii) the date the Company is required to give notice of the
record or payment date of such interest payment to the New York Stock Exchange
or other applicable self-regulatory organization or to Holders of the
Debentures.

                 (c)      The quarter in which any notice is given pursuant to
paragraphs (a) or (b) of this Section 4.2 shall be counted as one of the 20
quarters permitted in the maximum Extended Interest Payment Period permitted
under Section 4.1.

Section 4.3.     Limitation of Transactions.

                 If (i) the Company shall exercise its right to defer payment
of interest as provided in Section 4.1, or (ii) there shall have occurred any
Event of Default, as defined in the Indenture, then (a) the Company shall not
declare or pay any dividend on, make any distributions with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock or make any guarantee payment with respect thereto (other
than (i) purchases or acquisitions of shares of its common stock in connection
with the satisfaction by the Company of its obligations under any employee
benefit plans, (ii) as a result of a reclassification of its capital stock for
another class or series of its capital stock or (iii) the purchase of
fractional interests in shares of its capital stock pursuant to the conversion
or exchange provisions of such capital stock or security being converted or
exchanged) or make any

guarantee payment with respect thereto and (b) the Company shall not make any
payment of interest, principal or premium, if any, on or repay, repurchase or
redeem any debt securities issued by the Company which rank pari passu with or
junior to the Debentures.

                          COVENANT TO LIST ON EXCHANGE

SECTION 6.1.     Listing on an Exchange.

                 If the Debentures are to be issued as a Global Debenture in
connection with the distribution of the Debentures to the holders of the

                                    DUE 2036

                 PHILLIPS PETROLEUM COMPANY, a Delaware corporation (the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
______________ or registered assigns, the principal sum of _____________
Dollars ($___________) on _________, 2036, and to pay interest on said
principal sum from ____________, 1996, or from the most recent interest payment
date (each such date, an "Interest Payment Date") to which interest has been
paid or duly provided for, quarterly (subject to deferral as set forth herein)
in arrears on [March 31, June 30, September 30 and December 31] of each year
commencing _________, 1996, at the rate of ___% per annum until the principal
hereof shall have become due and payable, and on any overdue principal and
premium, if any, and (without duplication and to the extent that payment of
such interest is enforceable under applicable law) on any overdue installment
of interest at the same rate per annum compounded quarterly.  The amount of
interest payable on any Interest Payment Date shall be computed on the basis of
a 360-day year of twelve 30-day months.  In the event that any date on which
interest is payable on this Debenture is not a Business Day, then payment of
interest 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 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 such date.  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 Debenture (or one or more Predecessor Securities, as defined
in said Indenture) is registered at the close of business on the regular record
date for such interest installment, which shall be the close of business on the
business day next preceding such Interest Payment Date.   [IF PURSUANT TO THE
PROVISIONS OF THE INDENTURE THE DEBENTURES ARE NO LONGER REPRESENTED BY A

day next preceding such Interest Payment Date.] Any such interest installment

                                       12
<PAGE>   16
punctually paid or duly provided for shall forthwith cease to be payable to the
registered Holders on such regular record date and may be paid to the Person in
whose name this Debenture (or one or more Predecessor Securities) is registered
at the close of business on a special record date to be fixed by the Trustee
for the payment of such defaulted interest, notice whereof shall be given to
the registered Holders of this series of Debentures not less than 10 days prior
to such special record date, or may be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which the Debentures may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in the Indenture.  The principal of
(and premium, if any) and the interest on this Debenture shall be payable at
the office or agency of the Trustee maintained for that purpose in any coin or
currency of the United States of America that at the time of payment is legal
tender for payment of public and private debts; provided, however, that payment
of interest may be made at the option of the Company by check mailed to the
registered Holder at such address as shall appear in the Security Register.
Notwithstanding the foregoing, so long as the Holder of this Debenture is the
Institutional Trustee, the payment of the principal of (and premium, if any)
and interest on this Debenture will be made at such place and to such account
as may be designated by the Institutional Trustee.

                 The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all Senior Indebtedness, and this Debenture is issued
subject to the provisions of the Indenture with respect thereto.  Each Holder
of this Debenture, by accepting the same, (a) agrees to and shall be bound by
such provisions, (b) 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 so provided and (c) appoints the Trustee his or
her attorney-in-fact for any and all such purposes.  Each Holder hereof, by his
or her acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder
of Senior Indebtedness, whether now outstanding or hereafter incurred, and
waives reliance by each such holder upon said provisions.

                 This Debenture shall not be entitled to any benefit under the
Indenture hereinafter referred to, be valid or become obligatory for any
purpose until the Certificate of Authentication hereon shall have been signed
by or on behalf of the Trustee.

                 The provisions of this Debenture are continued on the reverse
side hereof and such continued provisions shall for all purposes have the same
effect as though fully set forth at this place.

                 This is one of the Securities of the series designated herein
refered to in the within-mentioned Indenture.

The Bank of New York
as Trustee


By                                
  --------------------------------
  Authorized Officer


                         (FORM OF REVERSE OF DEBENTURE)

                 This Debenture is one of a duly authorized series of
Debentures of the Company (herein sometimes referred to as the "Debentures"),
specified in the Indenture, all issued or to be issued in one or more series
under and pursuant to an Indenture dated as of _______, 1996, duly executed and
delivered between the Company and The Bank of New York as Trustee (the
"Trustee"), as supplemented by the First Supplemented Indenture dated as of
_______, 1996, between the Company and the Trustee (the Indenture as so
supplemented, the "Indenture"), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Company and the Holders of the Debentures.  By the terms of the
Indenture, the Debentures are issuable in series that may vary as to amount,
date of maturity, rate of interest and in other respects as





                                       14
<PAGE>   18
provided in the Indenture.  This series of Debentures is limited in aggregate
principal amount as specified in said First Supplemental Indenture.

                 Because of the occurrence and continuation of a Tax Event, in
certain circumstances, this Debenture may become due and payable at the
principal amount together with any interest accrued thereon (the "Redemption
Price").  The Redemption Price shall be paid prior to 12:00 noon, New York
time, on the date of such redemption or at such earlier time as the Company
determines.  The Company shall have the right to redeem this Debenture at the
option of the Company, without premium or penalty, in whole or in part at any
time on or after ________, 2001 (an "Optional Redemption"), or at any time in
certain circumstances upon the occurrence of a Tax Event, at a redemption price
equal to 100% of the principal amount plus any accrued but unpaid interest, to
the date of such redemption (the "Optional Redemption Price").  Any redemption
pursuant to this paragraph will be made upon not less than 30 days nor more
than 60 days notice, at the Optional Redemption Price.  If the Debentures are
only partially redeemed by the Company pursuant to an Optional Redemp- tion,
the Debentures will be redeemed pro rata or by lot or by any other method
utilized by the Trustee; provided that if, at the time of redemption, the
Debentures are registered as a Global Debenture, the Depositary shall determine
the principal amount of such Debentures held by each Debentureholder to be
redeemed in accordance with its procedures.

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

                 In case an Event of Default, as defined in the Indenture,
shall have occurred and be continuing, the principal of all of the Debentures
may be declared, and upon such declaration shall become, due and payable, in
the manner, with the effect and subject to the conditions provided in the
Indenture.

                 The Indenture contains provisions permitting the Company and
the Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Debentures of each series affected at the
time outstanding, as defined in the Indenture, to execute supplemental
indentures for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or of any
supplemental indenture or of modifying in any manner the rights of the Holders
of the Debentures; provided, however, that no such supplemental indenture shall
(i) extend the fixed maturity of any Debentures of any series, or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any premium payable upon the redemption





                                       15
<PAGE>   19
thereof, without the consent of the Holder of each Debenture so affected, or
(ii) reduce the aforesaid percentage of Debentures, the Holders of which are
required to consent to any such supplemental indenture, without the consent of
the Holders of each Debenture then outstanding and affected thereby.  The
Indenture also contains provisions permitting the Holders of a majority in
aggregate principal amount of the Debentures of any series at the time
outstanding affected thereby, on behalf of all of the Holders of the Debentures
of such series, to waive any past default in the performance of any of the
covenants contained in the Indenture, or established pursuant to the Indenture
with respect to such series, and its consequences, except a default in the
payment of the principal of or premium, if any, or interest on any of the
Debentures of such series.  Any such consent or waiver by the registered Holder
of this Debenture (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such Holder and upon all future Holders and owners
of this Debenture and of any Debenture issued in exchange herefor or in place
hereof (whether by registration of transfer or otherwise), irrespective of
whether or not any notation of such consent or waiver is made upon this
Debenture.

                 No reference herein to the Indenture and no provision of this
Debenture 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 Debenture at the time and place and at
the rate and in the money herein prescribed.

                 The Company shall have the right at any time during the term
of the Debentures and from time to time to extend the interest payment period
of such Debentures for up to 20 consecutive quarters (an "Extended Interest
Payment Period"), at the end of which period the Company shall pay all interest
then accrued and unpaid (together with interest thereon at the rate specified
for the Debentures to the extent that payment of such interest is enforceable
under applicable law); provided that no Extended Interest Payment Period may
last beyond the maturity date of the Debentures.  Before the termination of any
such Extended Interest Payment Period, the Company may further extend such
Extended Interest Payment Period, provided that such Extended Interest Payment
Period together with all such further extensions thereof shall not exceed 20
consecutive quarters or extend the maturity date of the Debentures.  At the
termination of any such Extended Interest Payment Period and upon the payment
of all accrued and unpaid interest and any additional amounts then due, the
Company may commence a new Extended Interest Payment Period.

                 As provided in the Indenture and subject to certain
limitations therein set forth, this Debenture is transferable by the registered
Holder hereof on the Security Register of the Company, upon surrender of this
Debenture for registration of

transfer at the office or agency of the Trustee in the City and State of New
York accompanied by a written instrument or instruments of transfer in form
satisfactory to the Company or the Trustee duly executed by the registered
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Debentures of authorized denominations and for the same aggregate
principal amount and series will be issued to the designated transferee or
transferees. No service charge will be made for any such transfer, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

                 Prior to due presentment for registration of transfer of this
Debenture, the Company, the Trustee, any paying agent and the Security
Registrar may deem and treat the registered holder hereof as the absolute owner
hereof (whether or not this Debenture shall be overdue and notwithstanding any
notice of ownership or writing hereon made by anyone other than the Security
Registrar) for the purpose of receiving payment of or on account of the
principal hereof and premium, if any, and interest due hereon and for all other
purposes, and neither the Company nor the Trustee nor any paying agent nor any
Security Registrar shall be affected by any notice to the contrary.

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

                 [The Debentures of this series are issuable only in registered
form without coupons in denominations of $25 and any integral multiple
thereof.]  [This Global Debenture is exchangeable for Debentures in definitive
form only under certain limited circumstances set forth in the Indenture.
Debentures of this series so issued are issuable only in registered form
without coupons in denominations of $25 and any integral multiple thereof.]  As
provided in the Indenture and subject to certain limitations [herein and]
therein set forth, Debentures of this series [so issued] are exchangeable for a
like aggregate principal amount of Debentures of this series of a different
authorized denomination, as requested by the Holder surrendering the same.

                 All terms used in this Debenture that are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

time to time of the Preferred Securities (as defined herein) of Phillips 66
Capital I, a Delaware statutory business trust (the "Issuer").

                 WHEREAS, pursuant to an Amended and Restated Declaration of
Trust (the "Declaration"), dated as of ________, 1996, among the trustees of
the Issuer named therein, the Guarantor, as sponsor, and the holders from time

                 (a)      This Preferred Securities Guarantee shall be held by
the Preferred Guarantee Trustee for the benefit of the Holders of the Preferred
Securities, and the Preferred Guarantee Trustee shall not transfer this
Preferred Securities Guarantee to any Person except a Holder of Preferred

actually known to a Responsible Officer of the Preferred Guarantee Trustee, the
Preferred Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Preferred Securities Guarantee, and use the same degree of care

                 provisions of this Preferred Securities Guarantee, and the
                 Preferred Guarantee Trustee shall not be liable except for the
                 performance of such duties and obligations as are specifically
                 set forth in this Preferred Securities Guarantee, and no
                 implied covenants or obligations shall be read into this
                 Preferred Securities Guarantee against the Preferred Guarantee
                 Trustee; and

                          (B)     in the absence of bad faith on the part of
                 the Preferred Guarantee Trustee, the Preferred 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
                 Preferred Guarantee Trustee and conforming to the requirements
                 of this Preferred Securities Guarantee; but in the case of any
                 such certificates or opinions that by any provision hereof are
                 specifically required to be furnished to the Preferred
                 Guarantee Trustee, the Preferred Guarantee Trustee shall be
                 under a duty to examine the same to determine

                 Preferred Securities Guarantee;

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

                 (iii) the Preferred Guarantee Trustee shall not be liable with

         the time, method and place of conducting any proceeding for any remedy
         available to the Preferred Guarantee Trustee, or exercising any trust

         own funds or otherwise incur personal financial liability in the
         performance of any of its duties or in the exercise of any of its
         rights or powers, if the Preferred 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
         Preferred Securities Guarantee or indemnity, reasonably satisfactory
         to the Preferred Guarantee Trustee, against such risk or liability is

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

                 (d)      If no Successor Preferred Guarantee Trustee shall

within 60 days after delivery to the Guarantor of an instrument of removal or
resignation, the resigning Preferred Guarantee Trustee may petition any court
of competent jurisdiction for appointment of a Successor Preferred Guarantee
Trustee.  Such court may thereupon, after prescribing such notice, if any, as

the acts or omissions to act of any Successor Preferred Guarantee Trustee.

SECTION 5.1      Guarantee

                 The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert.  The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
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 this
Preferred Securities Guarantee and of any liability to which





                                       13
<PAGE>   17
it applies or may apply, presentment, demand for payment, any right to require
a proceeding first against the Issuer or any other Person before proceeding
against the Guarantor, protest, notice of nonpayment, notice of dishonor,
notice of redemption and all other notices and demands.

SECTION 5.3      Obligations Not Affected

                 The obligations, covenants, agreements and duties of the
Guarantor under this Preferred Securities Guarantee shall in no way be affected
or impaired by reason of the happening from time to time of any of the
following:

                 (a)      the release or waiver, by operation of law or
otherwise, of the performance or observance by the Issuer of any express or
implied agreement, covenant, term or condition relating to the Preferred
Securities to be performed or observed by the Issuer;

                 (b)      the extension of time for the payment by the Issuer
of all or any portion of the Distributions, Redemption Price, Liquidation
Distribution or any other sums payable under the terms of the Preferred
Securities or the extension of time for the performance of any other obligation
under, arising out of, or in connection with, the Preferred Securities (other
than an extension of time for payment of Distributions, Redemption Price,
Liquidation Distribution or other sum payable that results from the extension
of any interest payment period on the Debentures or any extension of the
maturity date of the Debentures permitted by the Indenture);

                 (c)      any failure, omission, delay or lack of diligence on
the part of the Holders to enforce, assert or exercise any right, privilege,
power or remedy conferred on the Holders pursuant to the terms of the Preferred
Securities, or any action on the part of the Issuer granting indulgence or
extension of any kind;

                 (d)      the voluntary or involuntary liquidation,
dissolution, sale of any collateral, receivership, insolvency, bankruptcy,
assignment for the benefit of creditors, reorganization, arrangement,
composition or readjustment of debt of, or other similar proceedings affecting,
the Issuer or any of the assets of the Issuer;

                 (e)      any invalidity of, or defect or deficiency in, the
Preferred Securities;

                 (f)      the settlement or compromise of any obligation
guaranteed hereby or hereby incurred; or





                                       14
<PAGE>   18
                 (g)      any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a guarantor,
it being the intent of this Section 5.3 that the obligations of the Guarantor
hereunder shall be absolute and unconditional under any and all circumstances.

                 There shall be no obligation of the Holders to give notice to,
or obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4      Rights of Holders

                 (a)      The Holders of a Majority in liquidation amount of
the Preferred Securities have the right to direct the time, method and place of
conducting of any proceeding for any remedy available to the Preferred
Guarantee Trustee in respect of this Preferred Securities Guarantee or
exercising any trust or power conferred upon the Preferred Guarantee Trustee
under this Preferred Securities Guarantee.

                 (b)      If the Preferred Guarantee Trustee fails to enforce
such Preferred Securities Guarantee, any Holder of Preferred Securities may
institute a legal proceeding directly against the Guarantor to enforce the
Preferred Guarantee Trustee's rights under this Preferred Securities Guarantee,
without first instituting a legal proceeding against the Issuer, the Preferred
Guarantee Trustee or any other person or entity.  The Guarantor waives any
right or remedy to require that any action be brought first against the Issuer
or any other person or entity before proceeding directly against the Guarantor.

SECTION 5.5      Guarantee of Payment

                 This Preferred Securities Guarantee creates a guarantee of
payment and not of collection.

SECTION 5.6      Subrogation

                 The Guarantor shall be subrogated to all (if any) rights of
the Holders of Preferred Securities against the Issuer in respect of any
amounts paid to such Holders by the Guarantor under this Preferred Securities
Guarantee; provided, however, that the Guarantor shall not (except to the
extent required by mandatory provisions of law) be entitled to enforce or
exercise any right that it may acquire by way of subrogation or any indemnity,
reimbursement or other agreement, in all cases as a result of payment under
this Preferred Securities Guarantee, if, at the time of any such payment, any
amounts are due and unpaid under this Preferred Securities Guarantee.  If any
amount shall be paid to the Guarantor in violation of the preceding sentence,
the Guarantor agrees to hold such amount in trust for the Holders and to pay
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 Preferred
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

Declaration, then (a) the Guarantor shall not declare or pay any dividend on,
make any distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of shares of Common Stock in connection with the
satisfaction by the Guarantor of its obligations under any employee benefit
plans, (ii) as a result of a reclassifica- tion of the Guarantor's capital
stock or the exchange or conversion of one class or series of the Guarantor's
capital stock for another class or series of the Guarantor's capital stock or,
(iii) the purchase of fractional interests in shares of the Guarantor's capital
stock pursuant to the conversion or exchange provisions of such capital stock
of the Guarantor or the security being converted or exchanged) or make any
guarantee payments with respect to the foregoing or (b) the Guarantor shall not
make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities (including guarantees) issued by the
Guarantor which rank pari passu with or junior to the Debentures.

SECTION 6.2      Ranking

                 This Preferred Securities Guarantee will constitute an
unsecured obligation of the Guarantor and will rank (i) subordinate and junior
in right of payment to all other liabilities of the Guarantor, (ii) pari passu
with the most senior preferred or preference stock now or hereafter issued by
the Guarantor and with any guarantee now or hereafter entered into by the
Guarantor in respect of any Preferred or preference stock of any Affiliate of
the Guarantor, and (iii) senior to the Guarantor's common stock.

Securities or (iii) upon full payment of the amounts payable in accordance with
the Declaration upon liquidation of the Issuer.  Notwithstanding the foregoing,

reinstated, as the case may be, if at any time any Holder of Preferred
Securities must restore payment of any sums paid under the Preferred Securities
or under this Preferred Securities Guarantee.

after the occurrence of an Event of Default, transmit by mail, first class
postage prepaid, to the Holders of the Preferred Securities, notices of all
Events of Default actually known to a Responsible Officer of the Preferred
Guarantee Trustee, unless such defaults have been cured before the giving of
such notice, provided, that, the Preferred Guarantee Trustee shall be protected
in withholding such notice if and so long as a Responsible Officer of the
Preferred Guarantee Trustee in good faith determines that the withholding of
such notice is in the interests of the Holders of the Preferred Securities.

                 (b)      The Preferred Guarantee Trustee shall not be deemed
to have knowledge of any Event of Default unless the Preferred Guarantee
Trustee shall have received written notice, or of which a Responsible Officer
of the Preferred Guarantee Trustee charged with the administration of the
Declaration shall have obtained actual knowledge.

SECTION 2.8      Conflicting Interests

                 The Declaration shall be deemed to be specifically described
in this Preferred Securities Guarantee for the purposes of clause (i) of the
first proviso contained in Section 310(b) of the Trust Indenture Act.

                                  ARTICLE III
                          POWERS, DUTIES AND RIGHTS OF
                          PREFERRED GUARANTEE TRUSTEE

SECTION 3.1      Powers and Duties of the Preferred Guarantee Trustee

                 (a)      This Preferred Securities Guarantee shall be held by
the Preferred Guarantee Trustee for the benefit of the Holders of the Preferred
Securities, and the Preferred Guarantee Trustee shall not transfer this
Preferred Securities Guarantee to any Person except a Holder of Preferred
Securities exercising his or her rights pursuant to Section 5.4(b) or to a
Successor Preferred Guarantee Trustee on acceptance by such Successor Preferred
Guarantee Trustee of its appointment to act as Successor Preferred Guarantee
Trustee.  The right, title and interest of the Preferred Guarantee Trustee
shall automatically vest in any Successor Preferred Guarantee Trustee, and such
vesting and cessation of title shall be effective whether or not conveyancing
documents have been executed and delivered pursuant to the appointment of such
Successor Preferred Guarantee Trustee.

                 (b)      If an Event of Default actually known to a
Responsible Officer of the Preferred Guarantee Trustee has occurred and





                                       7

is continuing, the Preferred Guarantee Trustee shall enforce this Preferred
Securities Guarantee for the benefit of the Holders of the Preferred
Securities.

                 (c)      The Preferred 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 Preferred Securities Guarantee, and no
implied covenants shall be read into this Preferred Securities Guarantee
against the Preferred Guarantee Trustee.  In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6) and is
actually known to a Responsible Officer of the Preferred Guarantee Trustee, the
Preferred Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Preferred Securities Guarantee, 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 Preferred Securities Guarantee
shall be construed to relieve the Preferred 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 Preferred
                 Guarantee Trustee shall be determined solely by the express
                 provisions of this Preferred Securities Guarantee, and the
                 Preferred Guarantee Trustee shall not be liable except for the
                 performance of such duties and obligations as are specifically
                 set forth in this Preferred Securities Guarantee, and no
                 implied covenants or obligations shall be read into this
                 Preferred Securities Guarantee against the Preferred Guarantee
                 Trustee; and

                          (B)     in the absence of bad faith on the part of
                 the Preferred Guarantee Trustee, the Preferred 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
                 Preferred Guarantee Trustee and conforming to the requirements
                 of this Preferred Securities Guarantee; but in the case of any
                 such certificates or opinions that by any provision hereof are
                 specifically required to be furnished to the Preferred
                 Guarantee Trustee, the Preferred Guarantee Trustee shall be
                 under a duty to examine the same to determine





                                       8
<PAGE>   12
                 whether or not they conform to the requirements of this
                 Preferred Securities Guarantee;

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

                 (iii) the Preferred 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 of not less than a
         Majority in liquidation amount of the Preferred Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Preferred Guarantee Trustee, or exercising any trust
         or power conferred upon the Preferred Guarantee Trustee under this
         Preferred Securities Guarantee; and

                 (iv)     no provision of this Preferred Securities Guarantee
         shall require the Preferred Guarantee Trustee to expend or risk its
         own funds or otherwise incur personal financial liability in the
         performance of any of its duties or in the exercise of any of its
         rights or powers, if the Preferred 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
         Preferred Securities Guarantee or indemnity, reasonably satisfactory
         to the Preferred Guarantee Trustee, against such risk or liability is
         not reasonably assured to it.

                 (iii) Whenever, in the administration of this Preferred
         Securities Guarantee, the Preferred Guarantee Trustee shall deem it

                                       9
<PAGE>   13
         before taking, suffering or omitting any action hereunder, the
         Preferred Guarantee Trustee (unless other evidence is herein
         specifically prescribed) may, in the absence of bad faith on its part,
         request and conclusively rely upon an Officers' Certificate which,
         upon receipt of such request, shall be promptly delivered by the
         Guarantor.

                 (iv)     The Preferred Guarantee Trustee shall have no duty to
         see to any recording, filing or registration of any instrument (or any

         counsel, and the written advice or opinion of such counsel with
         respect to legal matters 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 accordance with such advice or opinion.
         Such counsel may be counsel to the Guarantor or any of its Affiliates
         and may include any of its employees.  The Preferred Guarantee Trustee
         shall have the right at any time to seek instructions concerning the
         administration of this Preferred Securities Guarantee from any court

                 (vi)     The Preferred Guarantee Trustee shall be under no
         obligation to exercise any of the rights or powers vested in it by
         this Preferred Securities Guarantee at the request or direction of any

         Guarantee Trustee such security and indemnity, reasonably satisfactory
         to the Preferred Guarantee Trustee, against the costs, expenses
         (including attorneys' fees and expenses and the expenses of the
         Preferred Guarantee Trustee's agents, nominees or custodians) 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 Preferred Guarantee Trustee; provided that, nothing
         contained in this Section 3.2(a)(vi) shall be taken to relieve the
         Preferred Guarantee Trustee, upon the occurrence of an Event of
         Default, of its obligation to exercise the rights and powers vested in
         it by this Preferred Securities Guarantee.

                 (vii)    The Preferred Guarantee Trustee shall not be bound to

         other evidence of indebtedness or other paper or document, but the

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

                 (ix)     Any action taken by the Preferred Guarantee Trustee
         or its agents hereunder shall bind the Holders of the Preferred
         Securities, and the signature of the Preferred Guarantee Trustee or
         its agents alone shall be sufficient and effective to perform any such
         action.  No third party shall be required to inquire as to the
         authority of the Preferred Guarantee Trustee to so act or as to its
         compliance with any of the terms and provisions of this Preferred
         Securities Guarantee, both of which shall be conclusively evidenced by

         liquidation amount of the Preferred Securities, (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
         conclusively relying on or acting in accordance with such
         instructions.

                 (b)      No provision of this Preferred Securities Guarantee
shall be deemed to impose any duty or obligation on the Preferred 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

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 Preferred Guarantee Trustee shall be construed to
be a duty.

Trustee may be appointed or removed without cause at any time by the Guarantor.

SECTION 5.1      Guarantee

                 The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert.  The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
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 this
Preferred Securities Guarantee and of any liability to which

SECTION 5.3      Obligations Not Affected

                 The obligations, covenants, agreements and duties of the
Guarantor under this Preferred Securities Guarantee shall in no way be affected
or impaired by reason of the happening from time to time of any of the
following:

                 (a)      the release or waiver, by operation of law or
otherwise, of the performance or observance by the Issuer of any express or
implied agreement, covenant, term or condition relating to the Preferred
Securities to be performed or observed by the Issuer;

                 (b)      the extension of time for the payment by the Issuer
of all or any portion of the Distributions, Redemption Price, Liquidation
Distribution or any other sums payable under the terms of the Preferred
Securities or the extension of time for the performance of any other obligation
under, arising out of, or in connection with, the Preferred Securities (other
than an extension of time for payment of Distributions, Redemption Price,
Liquidation Distribution or other sum payable that results from the extension
of any interest payment period on the Debentures or any extension of the
maturity date of the Debentures permitted by the Indenture);

                 (c)      any failure, omission, delay or lack of diligence on
the part of the Holders to enforce, assert or exercise any right, privilege,
power or remedy conferred on the Holders pursuant to the terms of the Preferred
Securities, or any action on the part of the Issuer granting indulgence or
extension of any kind;

                 (d)      the voluntary or involuntary liquidation,
dissolution, sale of any collateral, receivership, insolvency, bankruptcy,
assignment for the benefit of creditors, reorganization, arrangement,
composition or readjustment of debt of, or other similar proceedings affecting,
the Issuer or any of the assets of the Issuer;

                 (e)      any invalidity of, or defect or deficiency in, the
Preferred Securities;

                 (f)      the settlement or compromise of any obligation
guaranteed hereby or hereby incurred; or





                                       14
<PAGE>   18
                 (g)      any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a guarantor,
it being the intent of this Section 5.3 that the obligations of the Guarantor
hereunder shall be absolute and unconditional under any and all circumstances.

                 There shall be no obligation of the Holders to give notice to,
or obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4      Rights of Holders

                 (a)      The Holders of a Majority in liquidation amount of
the Preferred Securities have the right to direct the time, method and place of

Guarantee Trustee in respect of this Preferred Securities Guarantee or
exercising any trust or power conferred upon the Preferred Guarantee Trustee
under this Preferred Securities Guarantee.

                 (b)      If the Preferred Guarantee Trustee fails to enforce
such Preferred Securities Guarantee, any Holder of Preferred Securities may
institute a legal proceeding directly against the Guarantor to enforce the
Preferred Guarantee Trustee's rights under this Preferred Securities Guarantee,
without first instituting a legal proceeding against the Issuer, the Preferred
Guarantee Trustee or any other person or entity.  The Guarantor waives any
right or remedy to require that any action be brought first against the Issuer
or any other person or entity before proceeding directly against the Guarantor.

SECTION 5.5      Guarantee of Payment

                 This Preferred Securities Guarantee creates a guarantee of
payment and not of collection.

SECTION 5.6      Subrogation

                 The Guarantor shall be subrogated to all (if any) rights of
the Holders of Preferred Securities against the Issuer in respect of any
amounts paid to such Holders by the Guarantor under this Preferred Securities
Guarantee; provided, however, that the Guarantor shall not (except to the
extent required by mandatory provisions of law) be entitled to enforce or
exercise any right that it may acquire by way of subrogation or any indemnity,
reimbursement or other agreement, in all cases as a result of payment under
this Preferred Securities Guarantee, if, at the time of any such payment, any
amounts are due and unpaid under this Preferred Securities Guarantee.  If any
amount shall be paid to the Guarantor in violation of the preceding sentence,
the Guarantor agrees to hold such amount in trust for the Holders and to pay
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 Preferred
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

plans, (ii) as a result of a reclassifica- tion of the Guarantor's capital
stock or the exchange or conversion of one class or series of the Guarantor's
capital stock for another class or series of the Guarantor's capital stock or,
(iii) the purchase of fractional interests in shares of the Guarantor's capital

SECTION 3.1      Powers and Duties of the Preferred Guarantee Trustee

                 (a)      This Preferred Securities Guarantee shall be held by
the Preferred Guarantee Trustee for the benefit of the Holders of the Preferred
Securities, and the Preferred Guarantee Trustee shall not transfer this
Preferred Securities Guarantee to any Person except a Holder of Preferred
Securities exercising his or her rights pursuant to Section 5.4(b) or to a

actually known to a Responsible Officer of the Preferred Guarantee Trustee, the
Preferred Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Preferred Securities Guarantee, 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 Preferred Securities Guarantee
shall be construed to relieve the Preferred 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

                          (A)     the duties and obligations of the Preferred

                 provisions of this Preferred Securities Guarantee, and the
                 Preferred Guarantee Trustee shall not be liable except for the
                 performance of such duties and obligations as are specifically
                 set forth in this Preferred Securities Guarantee, and no
                 implied covenants or obligations shall be read into this
                 Preferred Securities Guarantee against the Preferred Guarantee
                 Trustee; and

                          (B)     in the absence of bad faith on the part of
                 the Preferred Guarantee Trustee, the Preferred 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
                 Preferred Guarantee Trustee and conforming to the requirements
                 of this Preferred Securities Guarantee; but in the case of any
                 such certificates or opinions that by any provision hereof are
                 specifically required to be furnished to the Preferred
                 Guarantee Trustee, the Preferred Guarantee Trustee shall be
                 under a duty to examine the same to determine

                 whether or not they conform to the requirements of this
                 Preferred Securities Guarantee;

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

                 (iii) the Preferred Guarantee Trustee shall not be liable with

         the time, method and place of conducting any proceeding for any remedy
         available to the Preferred Guarantee Trustee, or exercising any trust
         or power conferred upon the Preferred Guarantee Trustee under this
         Preferred Securities Guarantee; and

         own funds or otherwise incur personal financial liability in the
         performance of any of its duties or in the exercise of any of its
         rights or powers, if the Preferred 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
         Preferred Securities Guarantee or indemnity, reasonably satisfactory
         to the Preferred Guarantee Trustee, against such risk or liability is

         the Preferred Guarantee Trustee's or its agent's taking such action.

                 (x)      Whenever in the administration of this Preferred
         Securities Guarantee the Preferred Guarantee Trustee shall deem it
         desirable to receive instructions with respect to enforcing any remedy
         or right or taking any other action hereunder, the Preferred Guarantee
         Trustee (i) may request instructions from the Holders of a Majority in
         liquidation amount of the Preferred Securities, (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
         conclusively relying on or acting in accordance with such
         instructions.

                 (b)      No provision of this Preferred Securities Guarantee
shall be deemed to impose any duty or obligation on the Preferred 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 Preferred 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 Preferred Guarantee Trustee shall be construed to
be a duty.

                 Securities Guarantee

Guarantee Trustee and delivered to the Guarantor and the resigning Preferred
Guarantee Trustee.

within 60 days after delivery to the Guarantor of an instrument of removal or

of competent jurisdiction for appointment of a Successor Preferred Guarantee

the acts or omissions to act of any Successor Preferred Guarantee Trustee.

SECTION 5.1      Guarantee

                 The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert.  The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
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 this
Preferred Securities Guarantee and of any liability to which





                                       13
<PAGE>   17
it applies or may apply, presentment, demand for payment, any right to require
a proceeding first against the Issuer or any other Person before proceeding
against the Guarantor, protest, notice of nonpayment, notice of dishonor,
notice of redemption and all other notices and demands.

SECTION 5.3      Obligations Not Affected

                 The obligations, covenants, agreements and duties of the
Guarantor under this Preferred Securities Guarantee shall in no way be affected
or impaired by reason of the happening from time to time of any of the
following:

                 (a)      the release or waiver, by operation of law or
otherwise, of the performance or observance by the Issuer of any express or
implied agreement, covenant, term or condition relating to the Preferred
Securities to be performed or observed by the Issuer;

                 (b)      the extension of time for the payment by the Issuer
of all or any portion of the Distributions, Redemption Price, Liquidation
Distribution or any other sums payable under the terms of the Preferred
Securities or the extension of time for the performance of any other obligation
under, arising out of, or in connection with, the Preferred Securities (other
than an extension of time for payment of Distributions, Redemption Price,
Liquidation Distribution or other sum payable that results from the extension
of any interest payment period on the Debentures or any extension of the
maturity date of the Debentures permitted by the Indenture);

                 (c)      any failure, omission, delay or lack of diligence on
the part of the Holders to enforce, assert or exercise any right, privilege,
power or remedy conferred on the Holders pursuant to the terms of the Preferred
Securities, or any action on the part of the Issuer granting indulgence or
extension of any kind;

                 (d)      the voluntary or involuntary liquidation,
dissolution, sale of any collateral, receivership, insolvency, bankruptcy,
assignment for the benefit of creditors, reorganization, arrangement,
composition or readjustment of debt of, or other similar proceedings affecting,
the Issuer or any of the assets of the Issuer;

                 (e)      any invalidity of, or defect or deficiency in, the
Preferred Securities;

                 (f)      the settlement or compromise of any obligation
guaranteed hereby or hereby incurred; or





                                       14
<PAGE>   18
                 (g)      any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a guarantor,
it being the intent of this Section 5.3 that the obligations of the Guarantor
hereunder shall be absolute and unconditional under any and all circumstances.

                 There shall be no obligation of the Holders to give notice to,
or obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4      Rights of Holders

                 (a)      The Holders of a Majority in liquidation amount of
the Preferred Securities have the right to direct the time, method and place of
conducting of any proceeding for any remedy available to the Preferred
Guarantee Trustee in respect of this Preferred Securities Guarantee or
exercising any trust or power conferred upon the Preferred Guarantee Trustee
under this Preferred Securities Guarantee.

                 (b)      If the Preferred Guarantee Trustee fails to enforce
such Preferred Securities Guarantee, any Holder of Preferred Securities may
institute a legal proceeding directly against the Guarantor to enforce the
Preferred Guarantee Trustee's rights under this Preferred Securities Guarantee,
without first instituting a legal proceeding against the Issuer, the Preferred
Guarantee Trustee or any other person or entity.  The Guarantor waives any
right or remedy to require that any action be brought first against the Issuer
or any other person or entity before proceeding directly against the Guarantor.

SECTION 5.5      Guarantee of Payment

                 This Preferred Securities Guarantee creates a guarantee of
payment and not of collection.

SECTION 5.6      Subrogation

                 The Guarantor shall be subrogated to all (if any) rights of
the Holders of Preferred Securities against the Issuer in respect of any
amounts paid to such Holders by the Guarantor under this Preferred Securities
Guarantee; provided, however, that the Guarantor shall not (except to the
extent required by mandatory provisions of law) be entitled to enforce or
exercise any right that it may acquire by way of subrogation or any indemnity,
reimbursement or other agreement, in all cases as a result of payment under
this Preferred Securities Guarantee, if, at the time of any such payment, any
amounts are due and unpaid under this Preferred Securities Guarantee.  If any
amount shall be paid to the Guarantor in violation of the preceding sentence,
the Guarantor agrees to hold such amount in trust for the Holders and to pay
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 Preferred
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

Declaration, then (a) the Guarantor shall not declare or pay any dividend on,
make any distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of shares of Common Stock in connection with the
satisfaction by the Guarantor of its obligations under any employee benefit
plans, (ii) as a result of a reclassifica- tion of the Guarantor's capital
stock or the exchange or conversion of one class or series of the Guarantor's
capital stock for another class or series of the Guarantor's capital stock or,
(iii) the purchase of fractional interests in shares of the Guarantor's capital
stock pursuant to the conversion or exchange provisions of such capital stock
of the Guarantor or the security being converted or exchanged) or make any
guarantee payments with respect to the foregoing or (b) the Guarantor shall not
make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities (including guarantees) issued by the
Guarantor which rank pari passu with or junior to the Debentures.

SECTION 6.2      Ranking

                 This Preferred Securities Guarantee will constitute an
unsecured obligation of the Guarantor and will rank (i) subordinate and junior
in right of payment to all other liabilities of the Guarantor, (ii) pari passu
with the most senior preferred or preference stock now or hereafter issued by
the Guarantor and with any guarantee now or hereafter entered into by the
Guarantor in respect of any Preferred or preference stock of any Affiliate of
the Guarantor, and (iii) senior to the Guarantor's common stock.

Securities or (iii) upon full payment of the amounts payable in accordance with
the Declaration upon liquidation of the Issuer.  Notwithstanding the foregoing,
this Preferred Securities Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any Holder of Preferred
Securities must restore payment of any sums paid under the Preferred Securities
or under this Preferred Securities Guarantee.

incurred by reason of such Indemnified Person's negligence or willful
misconduct with respect to such acts or omissions.

         (b)     An Indemnified Person shall be fully protected in relying in
good faith upon the records of the Guarantor and upon such information,

after the occurrence of an Event of Default, transmit by mail, first class
postage prepaid, to the Holders of the Preferred Securities, notices of all
Events of Default actually known to a Responsible Officer of the Preferred

such notice, provided, that, the Preferred Guarantee Trustee shall be protected
in withholding such notice if and so long as a Responsible Officer of the
Preferred Guarantee Trustee in good faith determines that the withholding of
such notice is in the interests of the Holders of the Preferred Securities.

                 (b)      The Preferred Guarantee Trustee shall not be deemed
to have knowledge of any Event of Default unless the Preferred Guarantee
Trustee shall have received written notice, or of which a Responsible Officer
of the Preferred Guarantee Trustee charged with the administration of the
Declaration shall have obtained actual knowledge.

SECTION 2.8      Conflicting Interests

                 The Declaration shall be deemed to be specifically described

                          PREFERRED GUARANTEE TRUSTEE

SECTION 3.1      Powers and Duties of the Preferred Guarantee Trustee

                 (a)      This Preferred Securities Guarantee shall be held by
the Preferred Guarantee Trustee for the benefit of the Holders of the Preferred
Securities, and the Preferred Guarantee Trustee shall not transfer this
Preferred Securities Guarantee to any Person except a Holder of Preferred
Securities exercising his or her rights pursuant to Section 5.4(b) or to a
Successor Preferred Guarantee Trustee on acceptance by such Successor Preferred
Guarantee Trustee of its appointment to act as Successor Preferred Guarantee
Trustee.  The right, title and interest of the Preferred Guarantee Trustee
shall automatically vest in any Successor Preferred Guarantee Trustee, and such
vesting and cessation of title shall be effective whether or not conveyancing
documents have been executed and delivered pursuant to the appointment of such
Successor Preferred Guarantee Trustee.

                 (b)      If an Event of Default actually known to a
Responsible Officer of the Preferred Guarantee Trustee has occurred and

<PAGE>   11
is continuing, the Preferred Guarantee Trustee shall enforce this Preferred
Securities Guarantee for the benefit of the Holders of the Preferred
Securities.

                 (c)      The Preferred 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 Preferred Securities Guarantee, and no
implied covenants shall be read into this Preferred Securities Guarantee
against the Preferred Guarantee Trustee.  In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6) and is
actually known to a Responsible Officer of the Preferred Guarantee Trustee, the
Preferred Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Preferred Securities Guarantee, 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 Preferred Securities Guarantee
shall be construed to relieve the Preferred 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 Preferred
                 Guarantee Trustee shall be determined solely by the express
                 provisions of this Preferred Securities Guarantee, and the
                 Preferred Guarantee Trustee shall not be liable except for the
                 performance of such duties and obligations as are specifically
                 set forth in this Preferred Securities Guarantee, and no
                 implied covenants or obligations shall be read into this
                 Preferred Securities Guarantee against the Preferred Guarantee
                 Trustee; and

                          (B)     in the absence of bad faith on the part of
                 the Preferred Guarantee Trustee, the Preferred 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
                 Preferred Guarantee Trustee and conforming to the requirements
                 of this Preferred Securities Guarantee; but in the case of any
                 such certificates or opinions that by any provision hereof are
                 specifically required to be furnished to the Preferred
                 Guarantee Trustee, the Preferred Guarantee Trustee shall be
                 under a duty to examine the same to determine

                 whether or not they conform to the requirements of this
                 Preferred Securities Guarantee;

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

                 (iii) the Preferred 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 of not less than a
         Majority in liquidation amount of the Preferred Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Preferred Guarantee Trustee, or exercising any trust
         or power conferred upon the Preferred Guarantee Trustee under this
         Preferred Securities Guarantee; and

                 (iv)     no provision of this Preferred Securities Guarantee
         shall require the Preferred Guarantee Trustee to expend or risk its
         own funds or otherwise incur personal financial liability in the
         performance of any of its duties or in the exercise of any of its
         rights or powers, if the Preferred 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
         Preferred Securities Guarantee or indemnity, reasonably satisfactory
         to the Preferred Guarantee Trustee, against such risk or liability is
         not reasonably assured to it.

                 (iii) Whenever, in the administration of this Preferred
         Securities Guarantee, the Preferred Guarantee Trustee shall deem it
         desirable that a matter be proved or established





                                       9
<PAGE>   13
         before taking, suffering or omitting any action hereunder, the
         Preferred Guarantee Trustee (unless other evidence is herein
         specifically prescribed) may, in the absence of bad faith on its part,
         request and conclusively rely upon an Officers' Certificate which,
         upon receipt of such request, shall be promptly delivered by the
         Guarantor.

                 (iv)     The Preferred Guarantee Trustee shall have no duty to
         see to any recording, filing or registration of any instrument (or any

                 (v)      The Preferred Guarantee Trustee may consult with
         counsel, and the written advice or opinion of such counsel with
         respect to legal matters 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 accordance with such advice or opinion.
         Such counsel may be counsel to the Guarantor or any of its Affiliates
         and may include any of its employees.  The Preferred Guarantee Trustee
         shall have the right at any time to seek instructions concerning the
         administration of this Preferred Securities Guarantee from any court
         of competent jurisdiction.

                 (vi)     The Preferred Guarantee Trustee shall be under no
         obligation to exercise any of the rights or powers vested in it by
         this Preferred Securities Guarantee at the request or direction of any
         Holder, unless such Holder shall have provided to the Preferred
         Guarantee Trustee such security and indemnity, reasonably satisfactory
         to the Preferred Guarantee Trustee, against the costs, expenses
         (including attorneys' fees and expenses and the expenses of the
         Preferred Guarantee Trustee's agents, nominees or custodians) 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 Preferred Guarantee Trustee; provided that, nothing
         contained in this Section 3.2(a)(vi) shall be taken to relieve the
         Preferred Guarantee Trustee, upon the occurrence of an Event of
         Default, of its obligation to exercise the rights and powers vested in
         it by this Preferred Securities Guarantee.

                 (vii)    The Preferred Guarantee Trustee shall not be bound to

         other evidence of indebtedness or other paper or document, but the

         the trusts or powers hereunder or perform any duties hereunder either
         directly or by or through agents, nominees, custodians or attorneys,

         misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder.

                 (ix)     Any action taken by the Preferred Guarantee Trustee
         or its agents hereunder shall bind the Holders of the Preferred
         Securities, and the signature of the Preferred Guarantee Trustee or
         its agents alone shall be sufficient and effective to perform any such
         action.  No third party shall be required to inquire as to the
         authority of the Preferred Guarantee Trustee to so act or as to its
         compliance with any of the terms and provisions of this Preferred
         Securities Guarantee, both of which shall be conclusively evidenced by

         liquidation amount of the Preferred Securities, (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
         conclusively relying on or acting in accordance with such
         instructions.

                 (b)      No provision of this Preferred Securities Guarantee
shall be deemed to impose any duty or obligation on the Preferred 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 Preferred 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 Preferred Guarantee Trustee shall be construed to
be a duty.

SECTION 5.1      Guarantee

                 The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert.  The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
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 this
Preferred Securities Guarantee and of any liability to which

SECTION 5.3      Obligations Not Affected

                 The obligations, covenants, agreements and duties of the
Guarantor under this Preferred Securities Guarantee shall in no way be affected
or impaired by reason of the happening from time to time of any of the
following:

                 (a)      the release or waiver, by operation of law or
otherwise, of the performance or observance by the Issuer of any express or
implied agreement, covenant, term or condition relating to the Preferred
Securities to be performed or observed by the Issuer;

                 (b)      the extension of time for the payment by the Issuer
of all or any portion of the Distributions, Redemption Price, Liquidation
Distribution or any other sums payable under the terms of the Preferred
Securities or the extension of time for the performance of any other obligation
under, arising out of, or in connection with, the Preferred Securities (other
than an extension of time for payment of Distributions, Redemption Price,
Liquidation Distribution or other sum payable that results from the extension
of any interest payment period on the Debentures or any extension of the
maturity date of the Debentures permitted by the Indenture);

                 (c)      any failure, omission, delay or lack of diligence on
the part of the Holders to enforce, assert or exercise any right, privilege,
power or remedy conferred on the Holders pursuant to the terms of the Preferred
Securities, or any action on the part of the Issuer granting indulgence or
extension of any kind;

                 (d)      the voluntary or involuntary liquidation,
dissolution, sale of any collateral, receivership, insolvency, bankruptcy,
assignment for the benefit of creditors, reorganization, arrangement,
composition or readjustment of debt of, or other similar proceedings affecting,
the Issuer or any of the assets of the Issuer;

                 (e)      any invalidity of, or defect or deficiency in, the
Preferred Securities;

                 (f)      the settlement or compromise of any obligation
guaranteed hereby or hereby incurred; or





                                       14
<PAGE>   18
                 (g)      any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a guarantor,
it being the intent of this Section 5.3 that the obligations of the Guarantor
hereunder shall be absolute and unconditional under any and all circumstances.

                 There shall be no obligation of the Holders to give notice to,
or obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4      Rights of Holders

                 (a)      The Holders of a Majority in liquidation amount of
the Preferred Securities have the right to direct the time, method and place of
conducting of any proceeding for any remedy available to the Preferred
Guarantee Trustee in respect of this Preferred Securities Guarantee or
exercising any trust or power conferred upon the Preferred Guarantee Trustee
under this Preferred Securities Guarantee.

                 (b)      If the Preferred Guarantee Trustee fails to enforce
such Preferred Securities Guarantee, any Holder of Preferred Securities may
institute a legal proceeding directly against the Guarantor to enforce the
Preferred Guarantee Trustee's rights under this Preferred Securities Guarantee,
without first instituting a legal proceeding against the Issuer, the Preferred
Guarantee Trustee or any other person or entity.  The Guarantor waives any
right or remedy to require that any action be brought first against the Issuer
or any other person or entity before proceeding directly against the Guarantor.

SECTION 5.5      Guarantee of Payment

                 This Preferred Securities Guarantee creates a guarantee of
payment and not of collection.

SECTION 5.6      Subrogation

                 The Guarantor shall be subrogated to all (if any) rights of
the Holders of Preferred Securities against the Issuer in respect of any
amounts paid to such Holders by the Guarantor under this Preferred Securities
Guarantee; provided, however, that the Guarantor shall not (except to the
extent required by mandatory provisions of law) be entitled to enforce or
exercise any right that it may acquire by way of subrogation or any indemnity,
reimbursement or other agreement, in all cases as a result of payment under
this Preferred Securities Guarantee, if, at the time of any such payment, any
amounts are due and unpaid under this Preferred Securities Guarantee.  If any
amount shall be paid to the Guarantor in violation of the preceding sentence,
the Guarantor agrees to hold such amount in trust for the Holders and to pay
over such amount to the Holders.

Dear Sirs:

     I have acted as counsel for Phillips Petroleum Company, a Delaware
corporation (the "Company"), in connection with the preparation of the Company's
Registration Statement on Form S-3 (Registration No. 333-01209), filed by the
Company and Phillips 66 Capital I, Phillips 66 Capital II, Phillips 66 Capital
III and Phillips 66 Capital IV (each, a "Phillips Capital Trust" and, together,
the "Phillips Capital Trusts") with the Securities and Exchange Commission on
February 26, 1996 under the Securities Act of 1933, as amended (the "Securities
Act"), and Amendment No. 1 thereto, filed with the Commission on April 19, 1996
(such Registration Statement, as so amended, being hereinafter referred to as
the "Registration Statement"), in connection with the proposed offering from
time to time of an aggregate of up to $750,000,000 principal amount of
Subordinated Debt Securities ("Debt Securities") by the Company and Trust
Preferred Securities ("Preferred Securities") by the Phillips Capital Trusts.
The Debt Securities may be issued under one or more Indentures (the "Indenture")
proposed to be entered into between the Company and The Bank of New York as
Trustee. The Securities are proposed to be sold by the Company and the Phillips
Capital Trusts, to one or more underwriters (the "Underwriters"), pursuant to
one or more Underwriting Agreements between the Company and the Phillips Capital
Trusts and the Underwriters (the "Underwriting Agreement"). The Preferred
Securities of each Phillips Capital Trust are to be issued pursuant to the
Amended and Restated Declaration of Trust of such Phillips Capital Trust (each,
a "Declaration" and, collectively, the "Declarations"), each such Declaration
being among the Company, as sponsor and as the issuer of certain Securities to
be held by the Institutional Trustee (as defined below) of such Phillips Capital
Trust, The Bank of New York (Delaware), as Delaware trustee (the "Delaware
Trustee"), the Bank of New York, as institutional trustee (the "Institutional
Trustee") and T.C. Morris, John A. Carrig and L.L. McCall, as trustees
(together, the "Regular Trustees"). The Preferred Securities will be guaranteed

Ladies and Gentlemen:

                 We have acted as special counsel to Phillips 66 Capital I,
Phillips 66 Capital II, Phillips 66 Capital III and Phillips 66 Capital IV
(each, a "Phillips Capital Trust" and, together, the "Phillips Capital Trusts"),
each a statutory business trust formed under the laws of the State of Delaware,
in connection with the preparation of a Registration Statement on Form S-3
(Registration No. 333-1209), filed by Phillips Petroleum Company (the
"Company"), a corporation organized under the laws of the State of Delaware, and
the Phillips Capital Trusts with the Securities and Exchange Commission (the
"Commission") on February 26, 1996 under the Securities Act of 1933, as amended
(the "Act"), and Amendment No. 1 thereto, filed with the Commission on
the date hereof (such Registration Statement, as so amended, being 
hereinafter referred

to as the "Registration Statement"), relating to the public offering of
preferred securities (the "Trust Preferred Securities") of each of the Phillips
Capital Trusts, and certain other securities.


                 The Trust Preferred Securities of each Phillips Capital Trust
are to be issued pursuant to the Amended and Restated Declaration of Trust of
such Phillips Capital Trust (each, a "Declaration" and, collectively, the
"Declarations"), each such Declaration being among the Company, as sponsor and
as the issuer of certain debentures (the "Debentures") to be held by the
Institutional Trustee (as defined below) of such Phillips Capital Trust, The
Bank of New York (Delaware), as Delaware trustee (the "Delaware Trustee"), The
Bank of New York, as institutional trustee (the "Institutional Trustee"), and
T.C. Morris, John A. Carrig and L.L. McCall, as trustees (together, the "Regular
Trustees").

                 This opinion is being delivered in accordance with the
requirements of Item 601(b)(5) of Regulation S-K under the Act.  Capitalized
terms used but not otherwise defined herein have the meanings ascribed to them
in the Registration Statement.

                 In connection with this opinion, we have examined originals or
copies, certified or otherwise identified to our satisfaction, of (i) the
Certificate of Trust

Phillips 66 Capital IV

of each of the Phillips Capital Trusts (the "Certificates of Trust") filed with
the Secretary of State of the State of Delaware on February 23, 1996; (ii) the
form of the Declaration of each of the Phillips Capital Trusts (including the
designations of the terms of the Trust Preferred Securities of such Phillips
Capital Trust annexed thereto); (iii) the form of the Trust Preferred Securities
of each of the Phillips Capital Trusts; (iv) the form of the preferred
securities guarantee agreement (the "Preferred Securities Guarantee"), between
the Company and The Bank of New York, as guarantee trustee (the "Preferred
Securities Guarantee Trustee"); (v) the form of the Debentures; (vi) the form of
the junior subordinated indenture (the "Base Indenture"), between the Company
and The Bank of New York, as debt trustee (the "Debt Trustee"); and (vii) the
form of the supplemental indenture (the "Supplemental Indenture") (the Base
Indenture, together with any Supplemental Indenture, the "Indenture"), between
the Company and the Debt Trustee, in each case in the form filed as an exhibit
to the Registration Statement.  We have also examined originals or copies,
certified or otherwise identified to our satisfaction, of such other documents,
certificates and records as we have deemed necessary or appropriate as a basis
for the opinions set forth herein.

                 In our examination, we have assumed the legal capacity of all
natural persons, the genuineness of all signatures, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such copies.  In making our examination of
documents executed by parties other than the Phillips Capital Trusts, we have
assumed that such parties had the power, corporate or other, to enter into and
perform all obligations





<PAGE>   4

Phillips 66 Capital I
Phillips 66 Capital II
Phillips 66 Capital III
Phillips 66 Capital IV

thereunder and have also assumed the due authorization by all requisite action,
corporate or other, and execution and delivery by such parties of such
documents and that, except as set forth in paragraphs (2) and (3) below, such
documents constitute valid and binding obligations of such parties.  In
addition, we have assumed that the Declaration of each Phillips Capital Trust,
the Preferred Securities of each Phillips Capital Trust, the Preferred
Securities Guarantee, the Debentures and the Indenture when executed, will be
executed in substantially the form reviewed by us and that the terms of the
Debentures when established in conformity with the Indenture will not violate
any applicable law.  As to any facts material to the opinions expressed herein
which were not independently established or verified, we have relied upon oral
or written statements and representations of officers, trustees and other
representatives of the Company, the Phillips Capital Trusts and others.

                 Members of our firm are admitted to the bar in the States of
Delaware and New York, and we express no opinion as to the laws of any other
jurisdiction other than the laws of the United States of America to the extent
referred to specifically herein.

                 Based on and subject to the foregoing and to the other
qualifications and limitations set forth herein, we are of the opinion that:

                 1.       The Trust Preferred Securities of each Phillips
Capital Trust, when the Declaration of such Phillips Capital Trust is duly
executed and delivered by





<PAGE>   5

Phillips 66 Capital III
Phillips 66 Capital IV

the parties thereto and the terms of the Trust Preferred Securities of each
Phillips Capital Trust are established in accordance with the terms of the
Declaration of such Phillips Capital Trust, will be duly authorized for issuance
and, when issued and executed in accordance with such Declaration and delivered
and paid for as contemplated in the Registration Statement, will be validly
issued, fully paid and nonassessable, representing undivided beneficial
interests in the assets of such Phillips Capital Trust; and the holders of such
Preferred Securities will 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.  We bring to your
attention, however, that the holders of Preferred Securities of each Phillips
Capital Trust may be obligated, pursuant to the Declaration of such Phillips
Capital Trust, to (i) provide indemnity and/or security in connection with and
pay taxes or governmental charges arising from transfers of such Preferred
Securities and (ii) provide security and indemnity in connection with the
requests of or directions to the Institutional Trustee of such Phillips Capital
Trust to exercise its rights and powers under the Declaration of such Phillips
Capital Trust.

                 2.       The Preferred Securities Guarantee, when duly
executed and delivered by the parties thereto, will be a valid and binding
agreement of the Company, enforceable against the Company in accordance with
its terms, except to the extent that (a) enforcement thereof may be limited by
(i) bankruptcy, insolvency, reorganization, moratorium, or other similar laws
now or hereafter in effect relating to creditors' rights generally and (ii)
general principles of equity (regardless of whether enforceability is
considered in a proceeding at law or in equity).

                 3.       When the Indenture has been duly authorized, executed
and delivered, when the terms of the Debentures have been established in
conformity with the Indenture, and when the Debentures have been duly executed,
delivered, authenticated and issued in accordance with the Indenture and
delivered and paid for as contemplated in the Registration Statement, the
Debentures will be valid and binding obligations of the Company, entitled to
the benefits of the Indenture and enforceable against the Company in accordance
with their terms, except to the extent that enforcement thereof may be limited
by (i) bankruptcy, insolvency, reorganization, moratorium or other similar laws
now or hereafter in effect relating to creditors' rights generally and (ii)
general principles of equity (regardless of whether enforceability is
considered in a proceeding at law or in equity).

                 This opinion is furnished to you solely for your benefit in
connection with the filing of the Registration Statement and, except as set
forth below, is not to be used, circulated, quoted or otherwise referred to for
any other purpose or relied upon by any other person for any purpose without

                          ----------------------------------

Ladies and gentlemen:

                 We have acted as special tax counsel for Phillips Petroleum
Company, a Delaware corporation (the "Company"), Phillips 66 Capital I ("Trust
I"), Phillips 66 Capital II ("Trust II"), Phillips 66 Capital III ("Trust III")
and Phillips 66 Capital IV ("Trust IV"), each a statutory business trust formed
under the laws of Delaware, in connection with the above-captioned registration
statement on Form S-3 (the "Registration Statement") filed with the Securities
and Exchange Commission (the "Commission") for the purpose of registering (i)
Trust I's Preferred Securities representing undivided beneficial interests in
the assets of Trust I, Trust II's Preferred Securities representing undivided
beneficial interests in the assets of Trust II, Trust III's Preferred
Securities representing undivided beneficial interests in the assets of Trust
III and Trust IV's Preferred Securities representing undivided beneficial
interests in the assets of Trust IV (together the "Pre-

ferred Securities") and (ii) Junior Subordinated Deferrable Interest Debentures
issued by the Company to Trust I, Trust II, Trust III and Trust IV in
connection with the sale of the Preferred Securities.

                 We hereby confirm that, although the discussion set forth
under the heading "UNITED STATES FEDERAL INCOME TAXATION" in the form of
Prospectus Supplement for an offering Preferred Securities of Trust I, Trust
II, Trust III and Trust IV, filed as exhibits to the Registration Statement
(together the "Forms of Prospectus Supplement"), does not purport to discuss
all possible United States federal income tax consequences of the purchase,
ownership and disposition of Preferred Securities, in our opinion, such
discussion constitutes, in all material respects, a fair and accurate summary
of the United States federal income tax consequences of the purchase, ownership
and disposition of Preferred Securities, based upon current law.  It is
possible that contrary positions may be taken by the Internal Revenue Service
and that a court may agree with such contrary positions.

                 This opinion is furnished to you solely for your benefit in
connection with the filing of the Registration Statement and, except as set
forth below, is not to be used, circulated, quoted or otherwise referred to for
any other purpose or relied upon by any other person for any purpose without
our prior written consent.  We hereby consent to the use of our name under the
heading "LEGAL MATTERS" in the Forms of Prospectus Supplement and the filing of
this opinion with the Commission as Exhibit 8-A to the Registration Statement.
In giving this consent, we do not thereby admit that we are within the category
of persons whose consent is required under Section 7 of the Securities Act of
1933, as amended, or the rules and regulations of the Commission promulgated
thereunder.  This opinion is expressed as of the date hereof unless otherwise
expressly stated and applies only to the disclosure set forth in the Forms of
Prospectus Supplement filed as of the date hereof.  We disclaim any undertaking
to advise you of any subsequent changes of the facts stated or assumed herein
or any subsequent changes in applicable law.

                               Very truly yours,

                       CONSENT OF INDEPENDENT AUDITORS
