    Phillips Petroleum Company ("Phillips" or the "Company"), a Delaware
corporation, may from time to time offer (i) its unsecured senior debt
securities (the "Senior Debt Securities") or subordinated debt securities (the
"Subordinated Debt Securities") consisting of debentures, notes or other
evidences of indebtedness, (ii) shares of its preferred stock, with or without
par value (the "Preferred Stock"), which may be represented by depositary shares
as described herein, (iii) shares of its common stock, par value $1.25 per share
(the "Common Stock"), (iv) stock purchase contracts ("Stock Purchase Contracts")
to purchase Common Stock or Preferred Stock or (v) stock purchase units ("Stock
Purchase Units"), each representing ownership of a Stock Purchase Contract and
any of (x) Senior Debt Securities or Subordinated Debt Securities, (y) debt
obligations of third parties, including U.S. Treasury Securities, or (z)
Preferred Securities (as defined below) of a Phillips Capital Trust (as defined
below), securing the holder's obligation to purchase Common Stock under the
Stock Purchase Contract. Such securities may be offered in one or more separate
classes or series, in amounts, at prices and on terms to be determined by market
conditions at the time of sale and to be set forth in a supplement or
supplements to this Prospectus (a "Prospectus Supplement"). Such securities may
be sold for U.S. dollars, foreign denominated currency or currency units;
amounts payable with respect to any such securities may likewise be payable in
U.S. dollars, foreign denominated currency or currency units -- in each case as
the Company specifically designates.
 
    Phillips 66 Capital III, Phillips 66 Capital IV, Phillips 66 Capital V and
Phillips 66 Capital VI (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.

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 to provide certain indemnities in respect of and be responsible for

certain costs, expenses, debts and liabilities of each of Phillips 66 Capital
III, IV, V and VI under the Subordinated Debt Indenture and any supplemental
indenture thereto and pursuant to 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"

     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.

                                   THE TRUSTS
 
     Each of Phillips 66 Capital III, Phillips 66 Capital IV, Phillips 66
Capital V and Phillips 66 Capital VI 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, in the case of Phillips 66 Capital III and Phillips
66 Capital IV and on May   in the case of Phillips 66 Capital V and Phillips 66
Capital VI. 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, 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.

items, 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 and capital trusts. A statement setting forth the computation of the
unaudited ratios of earnings to fixed charges and of earnings to combined fixed
charges and preferred stock dividends is filed as an exhibit to the Registration
Statement of which this Prospectus is a part.
 
                                USE OF PROCEEDS
 
     Phillips intends to add the net proceeds from the sale of the Offered
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,
repayment of short-term commercial paper notes and/or other business
opportunities. Each Phillips Capital Trust will use all proceeds received from
the sale of the Offered Securities to purchase Subordinated Debt Securities from
Phillips.

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

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

Debt Securities; (11) any provisions for payment of additional amounts for taxes
and any provision for redemption, in the event the Company must comply with
reporting requirements in respect of a Debt Security or must pay such additional
amounts in respect of any Debt Security; (12) the terms and conditions, if any,
upon which the Debt Securities of such series may be repayable prior to maturity
at the option of the holder thereof (which option may be conditional) and the
price or prices in the currency or currency unit in which such Debt Securities
are payable; (13) the currency, currencies or currency units for which such Debt
Securities may be purchased and the currency, currencies or currency units in

Securities offered hereby will be transferable, at the corporate trust office of
the 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.
 
     If a Prospectus Supplement specifies that a series of 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
Debt Securities will be issued and the coin or currency in which the principal,
premium, if any, and interest, if any, on such Debt Securities will be payable,
which 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 Indentures contain no covenants or other provisions to afford
protection to holders of the 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
Debt Securities will be issued in fully registered form without coupons and in
denominations of $1,000 and integral multiples thereof. No service charge will
be made for any transfer or exchange of the 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 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 Debt Securities
and to payment on and transfer and exchange of such Debt Securities will be
described in the applicable Prospectus Supplement. Bearer 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 Debt
Securities may be surrendered for payment or transferred at the offices of the
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 Debt Securities in bearer form will be made at such paying
agencies outside of the United States as the Company may appoint.

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

     LIMITATION ON SALES AND LEASEBACKS. Neither the Company nor any Restricted

<PAGE>   10
 
sale and leaseback transaction, the Company or any Restricted Subsidiary has
expended or will expend for any Restricted Property an amount equal to (i) the
greater of (x) the net proceeds of such sale and leaseback transaction and (y)
the fair market value of the Restricted Property so leased at the time of
entering into such transaction, as determined by the Board of Directors of the
Company (the greater of the sums specified in clauses (x) and (y) being referred
to herein as the "Net Proceeds of such transaction"), and the Company elects to
designate such amount as satisfying any obligation it would otherwise have under
clause (c) hereof, or (ii) a part of the Net Proceeds of such transaction and
the Company elects to designate such amount as satisfying part of the obligation
it would otherwise have under clause (c) hereof and applies an amount equal to
the remainder of such Net Proceeds as provided in clause (c) hereof, or (c) the
Company, within 12 months of the consummation of any such sale and leaseback
transaction, applies an amount equal to the Net Proceeds of such transaction
(less any amount elected under clause (b) hereof) to the retirement of Funded
Debt of the Company ranking on a parity with the Securities of each series. This
restriction will not apply to certain sale and leaseback transactions (a)
between the Company and a Restricted Subsidiary or between Restricted
Subsidiaries, or (b) involving the taking back of a lease for a period of less
than three years.
 
     CERTAIN DEFINITIONS. "Attributable Debt" is defined to mean the total net
amount of rent (discounted at the rate per annum indicated in the Senior Debt
Indenture) required to be paid during the remaining term of any lease.
 
     "Consolidated Adjusted Net Assets" is defined to mean the total amount of
assets after deducting therefrom (a) all current liabilities (excluding any
thereof which are by their terms extendible or renewable at the option of the
obligor thereon to a time more than 12 months after the time as of which the
amount thereof is being computed), and (b) total prepaid expenses and deferred
charges.
 
     "Restricted Property" is defined to mean (a) any interest in property
located in the United States (including any interest in property located off the
coast of the United States operated pursuant to leases from any governmental
body) which is producing crude oil, natural gas or natural gas liquids in paying
quantities, or (b) any refining or manufacturing plant located in the United
States, except (i) related transportation or marketing facilities, or (ii) any

Board of Directors of the Company, is not a principal plant in relation to the
activities of the Company and its Restricted Subsidiaries as a whole.
 
     "Restricted Subsidiary" is defined to mean any Subsidiary which owns a
Restricted Property if substantially all of the tangible property in which such
Subsidiary has an interest is (a) located in the United States, or (b) is
located off the coast of the United States and is operated pursuant to leases
from any governmental body. The Company currently has no Restricted
Subsidiaries.
 
     "Subsidiary" is defined to mean a corporation, a majority of the
outstanding voting stock of which is owned, directly or indirectly, by the

other Subsidiaries.
 
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
laws of the United States or any State or the District of Columbia and shall
expressly assume the obligations of the Company under the Senior Debt Indenture.
If, upon any such consolidation, merger, conveyance or transfer of the Company
with or into any Person or of any Restricted Subsidiary with or to any other
Subsidiary, any Restricted Property of the Company or of any Restricted
Subsidiary or any shares of stock or indebtedness of any Restricted Subsidiary
would thereupon become subject to any Mortgage (other than a Mortgage permitted
under the limitation on liens described above, without the Company's having to
secure the Senior Debt Securities equally and ratably), the Company will secure
the Senior Debt Securities (together with, if the Company shall so determine,
other securities ranking on a parity with the Senior Debt Securities) prior to
all liens other than any theretofore existing.
 
                                        8
<PAGE>   11
 
Events of Default, Waiver, and Notice
 
     As to each series of Senior Debt Securities, an Event of Default is defined
in the Senior Debt Indenture as being: default for 30 days in payment of any
interest on the Senior Debt Securities of that series; default in payment of
principal and premium, if any, on the Senior Debt Securities of that series when
due either at maturity, upon redemption, by declaration or otherwise; default by
the Company in the performance of any other of the covenants or agreements in
the Senior Debt Indenture which shall not have been remedied for a period of 90
days after notice; and certain events of bankruptcy, insolvency, and
reorganization of the Company. The Senior Debt Indenture provides that the
Trustee may withhold notice to the Securityholders of any default (except in
payment of principal or of interest or premium on the Senior Debt Securities) if
the Trustee considers it in the interest of Securityholders to do so.
 
     The Senior Debt 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 Senior Debt Securities shall have occurred and be continuing, either
the Trustee or the holders of 25 percent in principal amount of the Senior Debt
Securities of all series affected thereby then outstanding may declare the
principal of all such Senior 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 Senior Debt Indenture or certain
events of bankruptcy, insolvency and reorganization of the Company, either the
Trustee or the holders of 25 percent in principal amount of all Senior Debt
Securities then outstanding (treated as one class) may declare the principal of
all Senior 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 Senior
Debt Securities) by the holders of a majority in principal amount of the Senior
Debt Securities of such series (or of all series, as the case may be) then
outstanding.
 
     The holders of a majority in principal amount of the Senior 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 Trustee under the Senior Debt Indenture, provided that the
Senior Debt Securityholders shall have offered to the Trustee reasonable
indemnity against expenses and liabilities. The Senior Debt Indenture requires
the annual filing by the Company with the Trustee of a certificate as to the
absence of certain defaults under the Senior Debt Indenture.
 
Modifications of the Indenture
 
     The Senior Debt Indenture contains provisions permitting the Company and
the Trustee, with the consent of the holders of not less than 66 2/3 percent in
principal amount of the Senior Debt Securities of all series affected by such
modification at the time outstanding, to modify the Senior Debt Indenture or any
supplemental indenture or the rights of the holders of the Senior Debt
Securities; provided that no such modification shall (i) extend the fixed
maturity of any Senior Debt 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
Senior Debt Securities payable in any coin or currency other than that provided
in the Senior Debt Securities, or impair or affect the right of any Senior Debt
Securityholder 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 Senior Debt Security so affected, or (ii) reduce the aforesaid
percentage of Senior Debt Securities the consent of the holders of which is
required for any such modification without the consent of the holders of each
Senior Debt Security affected.
 
Defeasance
 
     The Senior Debt Indenture provides that the Company, at the Company's
option: (a) will be Discharged from any and all obligations in respect of the
Senior Debt Securities of a series (except for certain obligations to register
the transfer or exchange of Senior Debt Securities, replace stolen, lost or
mutilated Senior Debt Securities, maintain paying agencies and hold moneys for
payment in trust) or (b) need not comply with
 
                                        9
<PAGE>   12
 
certain restrictive covenants of the Senior Debt Indenture (including those
described herein), in each case if the Company deposits, in trust with the
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 Senior Debt Securities of such series on the dates such payments
are due in accordance with the terms of such Senior Debt Securities. To exercise
any such option, the Company is required to deliver to the 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 Senior 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 Senior Debt Securities would not be delisted from such exchange
as a result of the exercise of such option.
 
Governing Law
 
     The Senior Debt Indenture and the Senior Debt Securities will be governed
by, and construed in accordance with, the internal laws of the State of New
York.
 
The Trustee
 
     The Company may have normal banking relationships with U.S. Bank Trust
National Association as successor to the Continental Bank National Association
in the ordinary course of business.
 
CERTAIN TERMS OF THE SUBORDINATED DEBT SECURITIES
 
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.
 
Issuance of Subordinated Debt Securities to a Phillips Capital Trust
 
     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.
 
Certain Covenants of the Company
 
     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 (i) there shall have occurred any event that
would constitute an Event of 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, purchase 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 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
 
                                       10
<PAGE>   13
 
(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.
 
     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
securities (including guarantees) issued by the Company which rank pari passu
with or junior to such Subordinated Debt Securities.
 
     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 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 percent 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
purposes and (iii) to use its reasonable efforts to cause each holder of Trust
Securities to be treated as owning an undivided beneficial interest in the
Subordinated Debt Securities.
 
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
laws of the United States or any State or the District of Columbia and shall
expressly assume the obligations of the Company under the Subordinated Debt
Indenture.
 
Events of Default, Waiver and Notice
 
     The Subordinated Debt Indenture provides that 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
 
                                       11
<PAGE>   14
 
          (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.
 
The Subordinated Debt Indenture provides that the 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.
 
     The Subordinated Debt 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 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
Subordinated Debt Indenture or certain events of bankruptcy, insolvency and
reorganization of the Company shall have occurred and be continuing, either the
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.
 
     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 Trustee under the Subordinated Debt Indenture, provided
that the holders of the Subordinated Debt Securities shall have offered to the
Debt Trustee reasonable indemnity against expenses and liabilities. The
Subordinated Debt Indenture requires the annual filing by the Company with the
Trustee of a certificate as to the absence of certain defaults under the
Subordinated Debt Indenture.
 
Modification of the Indenture
 
     The Subordinated Debt Indenture contains provisions permitting the Company
and the 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 Subordinated Debt
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 Subordinated Debt Security, or reduce the
principal amount thereof (including in the case of a discounted Subordinated
Debt 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 Subordinated
Debt 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 Subordinated
Debt Security affected.
 
Defeasance and Discharge
 
     The Subordinated Debt 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
 
                                       12
<PAGE>   15
 
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 Subordinated Debt Indenture (including those described herein), in each
case if the Company deposits, in trust with the 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 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.
 
Governing Law
 
     The Subordinated Debt Indenture and the Subordinated Debt Securities will
be governed by, and construed in accordance with, the internal laws of the State
of New York.
 
The Trustee
 
     The Company may have normal banking relationships with The Bank of New York
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 periodic
basis to holders of such Preferred Securities as of a record date in each period
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
 
                                       13
<PAGE>   16
 
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.

               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 of the Company." 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.
 
                                       15
<PAGE>   18
 
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 Trust, the Preferred Guarantee Trustee or any other person or entity.
Notwithstanding the foregoing, if the Company
 
                                       16
<PAGE>   19
 
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.
 
     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.
 
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 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.
 
                        EFFECT OF OBLIGATIONS UNDER THE
                 SUBORDINATED DEBT SECURITIES AND THE GUARANTEE
 
     As set forth in the Declaration, the sole purpose of each of the Phillips
Capital Trusts is to issue the Trust Securities evidencing undivided beneficial
interests in the assets of each of the Phillips Capital Trusts, 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 applicable Phillips Capital Trust shall not be
obligated to pay, directly or indirectly, all costs, expenses, debt, and
obligations of the applicable Phillips Capital 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 applicable Phillips
Capital Trust to, among other things, engage in any activity that is not
consistent with the purposes of the applicable Phillips Capital Trust.
 
                                       17
<PAGE>   20
 
     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." If Phillips does not make
interest payments on the Subordinated Debt Securities purchased by the
applicable Phillips Capital Trust, it is expected that the applicable Phillips
Capital 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 applicable Phillips Capital 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 applicable Phillips Capital Trust
as its sole asset. The Guarantee, when taken together with Phillips' 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 applicable Phillips Capital 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" in any accompanying Prospectus Supplement, 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
Subordinated 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 applicable
Phillips Capital Trust, the Guarantee Trustee, or any other person or entity.
 
     Phillips and each of the Phillips Capital Trusts 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."

                         DESCRIPTION OF PREFERRED STOCK
 
     The following description of the terms of the Preferred Stock sets forth
certain general terms and provisions of the Preferred Stock to which any
Prospectus Supplement may relate. Certain terms of any series of the Preferred
Stock offered by any Prospectus Supplement will be described in the Prospectus
Supplement relating to such series of the Preferred Stock. If so indicated in
the Prospectus Supplement, the terms of any such series may differ from the
terms set forth below. The description of certain provisions of the Preferred
Stock set forth below and in any Prospectus Supplement does not purport to be
complete and is subject to and qualified in its entirety by reference to the
Certificate of Designations relating to such series of the Preferred Stock,
which will be filed with the Commission promptly after the offering of such
series of Preferred Stock.
 
GENERAL
 
     Under the Company's Restated Certificate of Incorporation (the "Charter"),
the Board of Directors of the Company (the "Board of Directors") is authorized,
without further stockholder action, to provide for the issuance of up to
300,000,000 shares of preferred stock, with or without par value, in one or more
series, with such voting powers and with such designations, preferences and
relative, participating, optional or other special rights, and qualifications,
limitations or restrictions, as shall be set forth in resolutions providing for
the issue thereof adopted by the Board of Directors or a duly authorized
committee thereof. The Company may amend from time to time the Charter to
increase the number of authorized shares of preferred stock in the manner
provided in the Charter and the Delaware General Corporation Law ("DGCL").
 
     The Preferred Stock shall have the dividend, liquidation, redemption,
voting and conversion rights set forth in the Prospectus Supplement relating to
a particular series of the Preferred Stock. Reference is made to the Prospectus
Supplement relating to the particular series of the Preferred Stock offered
thereby for specific terms, including: (i) the title and liquidation preference
per share of such Preferred Stock and the number of shares offered; (ii) the
price at which such Preferred Stock will be issued; (iii) the dividend rate (or
method of calculation), the dates on which dividends shall be payable, whether
such dividends shall be cumulative or noncumulative and, if cumulative, the
dates from which dividends shall commence to accumulate; (iv) any redemption or
sinking fund provisions of such Preferred Stock; (v) any conversion provisions
of such Preferred Stock; (vi) whether the Company has elected to offer
Depositary Shares with respect to such Preferred Stock as described below under
"Description of Depositary Shares" (vii) the voting rights, if any, of such
Preferred Stock; and (viii) any additional dividend, liquidation, redemption,
sinking fund and other rights, preferences, privileges, limitations and
restrictions of such Preferred Stock.
 
     The Preferred Stock will, when issued, be fully paid and nonassessable.
Unless otherwise specified in the Prospectus Supplement relating to a particular
series of the Preferred Stock, each series of the Preferred Stock will rank on a
parity as to dividends and distributions in the event of a liquidation with any
outstanding preferred stock of the Company and each other series of the
Preferred Stock.
 
                        DESCRIPTION OF DEPOSITARY SHARES
 
     The description set forth below and in any Prospectus Supplement of certain
provisions of the Deposit Agreement (as defined below) and of the Depositary
Shares and Depositary Receipts summarizes the material terms of the Deposit
Agreement and of the Depositary Shares and Depositary Receipts, and is qualified
in its entirety by reference to, the form of Deposit Agreement and form of
Depositary Receipts relating to each series of the Preferred Stock.
 
GENERAL
 
     The Company may, at its option, elect to have shares of Preferred Stock be
represented by Depositary Shares. The shares of any series of the Preferred
Stock underlying the Depositary Shares will be deposited under a separate
deposit agreement (the "Deposit Agreement") between the Company and a bank or
trust company selected by the Company (the "Preferred Stock Depositary"). The
Prospectus Supplement relating to a series of Depositary Shares will set forth
the name and address of the Preferred Stock Depositary. Subject
 
                                       19
<PAGE>   22
 
to the terms of the Deposit Agreement, each owner of a Depositary Share will be
entitled, proportionately, to all the rights, preferences and privileges of the
Preferred Stock represented thereby (including dividend, voting, redemption,
conversion, exchange and liquidation rights).
 
     The Depositary Shares will be evidenced by Depositary Receipts issued
pursuant to the Deposit Agreement, each of which will represent the applicable
interest in a number of shares of a particular series of the Preferred Stock
described in the applicable Prospectus Supplement.
 
     A holder of Depositary Shares will be entitled to receive the shares of
Preferred Stock (but only in whole shares of Preferred Stock) underlying such
Depositary Shares. If the Depositary Receipts delivered by the holder evidence a
number of Depositary Shares in excess of the whole number of shares of Preferred
Stock to be withdrawn, the Depositary will deliver to such holder at the same
time a new Depositary Receipt evidencing such excess number of Depositary
Shares.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
     The Preferred Stock Depositary will distribute all cash dividends or other
cash distributions in respect to the Preferred Stock to the record holders of
Depositary Receipts in proportion, insofar as possible, to the number of
Depositary Shares owned by such holders.
 
     In the event of a distribution other than in cash in respect to the
Preferred Stock, the Preferred Stock Depositary will distribute property
received by it to the record holders of Depositary Receipts in proportion,
insofar as possible, to the number of Depositary Shares owned by such holders,
unless the Preferred Stock Depositary determines that it is not feasible to make
such distribution, in which case the Preferred Stock Depositary may, with the
approval of the Company, adopt such method as it deems equitable and practicable
for the purpose of effecting such distribution, including sale (at public or
private sale) of such property and distribution of the net proceeds from such
sale to such holders.
 
     The amount so distributed in any of the foregoing cases will be reduced by
any amount required to be withheld by the Company or the Preferred Stock
Depositary on account of taxes.
 
CONVERSION AND EXCHANGE
 
     If any Preferred Stock underlying the Depositary Shares is subject to
provisions relating to its conversion or exchange as set forth in the Prospectus
Supplement relating thereto, each record holder of Depositary Shares will have
the right or obligation to convert or exchange such Depositary Shares pursuant
to the terms thereof.
 
REDEMPTION OF DEPOSITARY SHARES
 
     If Preferred Stock underlying the Depositary Shares is subject to
redemption, the Depositary Shares will be redeemed from the proceeds received by
the Preferred Stock Depositary resulting from the redemption, in whole or in
part, of the Preferred Stock held by the Preferred Stock Depositary. The
redemption price per Depositary Share will be equal to the aggregate redemption
price payable with respect to the number of shares of Preferred Stock underlying
the Depositary Shares. Whenever the Company redeems Preferred Stock from the
Preferred Stock Depositary, the Preferred Stock Depositary will redeem as of the
same redemption date a proportionate number of Depositary Shares representing
the shares of Preferred Stock that were redeemed. If less than all the
Depositary Shares are to be redeemed, the Depositary Shares to be redeemed will
be selected by lot or pro rata as may be determined by the Company.
 
     After the date fixed for redemption, the Depositary Shares so called for
redemption will no longer be deemed to be outstanding and all rights of the
holders of the Depositary Shares will cease, except the right to receive the
redemption price upon such redemption. Any funds deposited by the Company with
the Preferred Stock Depositary for any Depositary Shares which the holders
thereof fail to redeem shall be returned to the Company after a period of two
years from the date such funds are so deposited.
 
                                       20
<PAGE>   23
 
VOTING
 
     Upon receipt of notice of any meeting at which the holders of any shares of
Preferred Stock underlying the Depositary Shares are entitled to vote, the
Preferred Stock Depositary will mail the information contained in such notice to
the record holders of the Depositary Receipts. Each record holder of such
Depositary Receipts on the record date (which will be the same date as the
record date for the Preferred Stock) will be entitled to instruct the Preferred
Stock Depositary as to the exercise of the voting rights pertaining to the
number of shares of Preferred Stock underlying such holder's Depositary Shares.
The Preferred Stock Depositary will endeavor, insofar as practicable, to vote
the number of shares of Preferred Stock underlying such Depositary Shares in
accordance with such instructions, and the Company will agree to take all
reasonable action which nay he deemed necessary by the Preferred Stock
Depositary in order to enable the Preferred Stock Depositary to do so. The
Preferred Stock Depositary will abstain from voting the Preferred Stock to the
extent it does not receive specific written instructions from holders of
Depositary Receipts representing such Preferred Stock.
 
RECORD DATE
 
     Whenever (i) any cash dividend or other cash distribution shall become
payable, any distribution other than cash shall be made, or any rights,
preferences or privileges shall be offered with respect to the Preferred Stock,
or (ii) the Preferred Stock Depositary shall receive notice of any meeting at
which holders of Preferred Stock are entitled to vote or of which holders of
Preferred Stock are entitled to notice, or of the mandatory conversion of or any
election on the part of the Company to call for the redemption of any Preferred
Stock, the Preferred Stock Depositary shall in each such instance fix a record
date (which shall be the same as the record date for the Preferred Stock) for
the determination of the holders of Depositary Receipts (x) who shall be
entitled to receive such dividend, distribution, rights, preferences or
privileges or the net proceeds of the sale thereof or (y) who shall be entitled
to give instructions for the exercise of voting rights at any such meeting or to
receive notice of such meeting or of such redemption or conversion, subject to
the provisions of the Deposit Agreement.
 
AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT
 
     The form of Depositary Receipt and any provision of the Deposit Agreement
may at any time be amended by agreement between the Company and the Preferred
Stock Depositary. However, any amendment which imposes or increases any fees,
taxes or other charges payable by the holders of Depositary Receipts (other than
taxes and other governmental charges, fees and other expenses payable by such
holders as slated under "Charges of Preferred Stock Depositary"), or which
otherwise prejudices any substantial existing right of holders of Depositary
Receipts, will not take effect as to outstanding Depositary Receipts until the
expiration of 90 days after notice of such amendment has been mailed to the
record holders of outstanding Depositary Receipts.
 
     Whenever so directed by the Company, the Preferred Stock Depositary will
terminate the Deposit Agreement by mailing notice of such termination to the
record holders of all Depositary Receipts then outstanding at least 30 days
prior to the date fixed in such notice for such termination. The Preferred Stock
Depositary may likewise terminate the Deposit Agreement if at any time 45 days
shall have expired after the Preferred Stock Depositary shall have delivered to
the Company a written notice of its election to resign and a successor
depositary shall not have been appointed and accepted its appointment. If any
Depositary Receipts remain outstanding after the date of termination, the
Preferred Stock Depositary thereafter will discontinue the transfer of
Depositary Receipts, will suspend the distribution of dividends to the holders
thereof, and will not give any further notices (other than notice such
termination) or perform any further acts under the Deposit Agreement except as
provided below and except that the Preferred Stock Depositary will continue (i)
to collect dividends on the Preferred Stock and any other distributions with
respect thereto and (ii) to deliver the Preferred Stock together with such
dividends and distributions and the net proceeds of any sales of rights,
preferences, privileges or other property, without liability for interest
thereon, in exchange for Depositary Receipts surrendered. At any time after the
expiration of two years from the date of termination, the Preferred Stock
Depositary may sell the Preferred Stock then held by it at public or private
sales, at such
 
                                       21
<PAGE>   24
 
place or places and upon such terms as it deems proper and may thereafter hold
the net proceeds of any such sale, together with any money and other property
then held by it without liability for interest thereon, for the pro rata benefit
of the holders of Depositary Receipts which have not been surrendered.
 
CHARGES OF PREFERRED STOCK DEPOSITARY
 
     The Company will pay all charges of the Preferred Stock Depositary
including charges in connection with the initial deposit of the Preferred Stock,
the initial issuance of the Depositary Receipts, the distribution of information
to the holders of Depositary Receipts with respect to matters on which Preferred
Stock is entitled to vote, withdrawals of the Preferred Stock by the holders of
Depositary Receipts or redemption or conversion of the Preferred Stock, except
for taxes (including transfer taxes, if any) and other governmental charges and
such other charges as are expressly provided in the Deposit Agreement to be at
the expense of holders of Depositary Receipts or persons depositing Preferred
Stock.
 
MISCELLANEOUS
 
     Neither the Preferred Stock Depositary nor the Company will be liable if it
is prevented or delayed by law or any circumstance beyond its control in
performing its obligations under the Deposit Agreement. The obligations of the
Preferred Stock Depositary under the Deposit Agreement are limited to performing
its duties thereunder without negligence or bad faith. The obligations of the
Company under the Deposit Agreement are limited to performing its duties
thereunder in good faith. Neither the Company nor the Preferred Stock Depositary
is obligated to prosecute or defend any legal proceeding in respect of any
Depositary Shares or Preferred Stock unless satisfactory indemnity is furnished.
The Company and the Preferred Stock Depositary are entitled to rely upon advice
of or information from counsel, accountants or other persons believed to be
competent and on documents believed to be genuine.
 
     The Preferred Stock Depositary may resign at any time or be removed by the
Company, effective upon the acceptance by its successor of its appointment;
provided, that if a successor Preferred Stock Depositary has not been appointed
or accepted such appointment within 45 days after the Preferred Stock Depositary
has delivered a notice of election to resign to the Company, the Preferred Stock
Depositary may terminate the Deposit Agreement. See "Amendment and Termination
of Deposit Agreement" above.
 
                    DESCRIPTION OF STOCK PURCHASE CONTRACTS
                            AND STOCK PURCHASE UNITS
 
     The Company may issue Stock Purchase Contracts representing contracts
obligating holders to purchase from the Company and the Company to sell to the
holders a specified number of shares of Common Stock or Preferred Stock at a
future date or dates. The price per share of Common Stock or Preferred Stock may
be fixed at the time the Stock Purchase Contracts are issued or may be
determined by reference to a specific formula set forth in the Stock Purchase
Contracts. The Stock Purchase Contracts may be issued separately or as a part of
units ("Stock Purchase Units") consisting of a Stock Purchase Contract and
either (x) Senior Debt Securities, Subordinated Debt Securities (y) debt
obligations of third parties including U.S. Treasury securities, or (z)
Preferred Securities of a Phillips Capital Trust, securing the holder's
obligations to purchase the Common Stock or Preferred Stock under the Stock
Purchase Contracts. The Stock Purchase Contracts may require the Company to make
periodic payments to the holders of the Stock Purchase Units or vice versa, and
such payments may be unsecured or prefunded on some basis. The Stock Purchase
Contracts may require holders to secure their obligations thereunder in a
specified manner and in certain circumstances the Company may deliver newly
issued prepaid stock purchase contracts ("Prepaid Securities") upon release to a
holder of any collateral securing each holder's obligations under the original
Stock Purchase Contract.
 
     The applicable Prospectus Supplement will describe the terms of any Stock
Purchase Contracts or Stock Purchase Units and, if applicable, Prepaid
Securities. The description in the Prospectus Supplement will not purport to be
complete and will be qualified in its entirety by reference to the Stock
Purchase Contracts, the collateral arrangements and depositary arrangements, if
applicable, relating to such Stock Purchase Contracts
 
                                       22

or Stock Purchase Units and, if applicable, the Prepaid Securities and the
document pursuant to which such Prepaid Securities will be issued.
 
                          DESCRIPTION OF COMMON STOCK
 
     The following summary does not purport to be complete and is subject in all
respects to the applicable provisions of the DGCL and the Charter.
 
     General.  The Company is authorized to issue up to 500,000,000 shares of
Common Stock. At December 31, 1997, the Company had outstanding 306,380,511
shares of Common Stock (including 14,000,882 shares held in its treasury) and
had reserved approximately 29,125,863 shares of Common Stock for issuance under
various employee or non-employee director incentive, compensation and option
plans and under the Company's Dividend Reinvestment Plan.
 
     Dividends.  Holders of Common Stock are entitled to receive dividends when,
as and if declared by the Board of Directors out of funds legally available
therefor, provided that, so long as any shares of preferred stock are
outstanding, no dividends (other than dividends payable in Common Stock) or
other distributions (including redemptions and purchases) may be made with
respect to the Common Stock unless full dividends on the shares of preferred
stock, including accumulations in the case of cumulative preferred stock, have
been paid.
 
     Voting Rights.  Subject to the rights, if any, of the holders of any series
of preferred stock, all voting rights are vested in the holders of shares of
Common Stock, each share being entitled to one vote on all matters presented for
a vote, including the election of directors. Holders of shares of Common Stock
have noncumulative voting rights, which means that the holders of more than 50
percent of the shares voting for the election of directors can elect 100 percent
of the directors, and, in such event, the holders of the remaining shares voting
for the election of directors will not be able to elect any directors.
 
     Rights Upon Liquidation.  In the event of the liquidation, dissolution or
winding up of the Company, whether voluntary or involuntary, after there have
been paid to or set aside for the holders of all series of preferred stock the
full preferential amounts to which such holders are entitled, the holders of
Common Stock will be entitled to share equally and ratably in any assets
remaining after the payment of all debts and liabilities of the Company.
 
     Preferred Share Purchase Rights.  The Company has outstanding one Preferred
Share Purchase Right ("Right") for each outstanding share of the Company's
Common Stock. Each Right entitles the registered holder to purchase from the
Company one one-hundredth of a share of Series B Junior Participating Preferred
Stock, par value $1.00 per share (the "Series B Preferred Stock"), of the
Company at a price of $75 per one one-hundredth of a share of Series B Preferred
Stock, subject to adjustment or to purchase shares of Common Stock or the stock
of an acquiring company at a discount in the event that any person or group of
affiliated persons acquires beneficial ownership of 20% or more of the Company's
outstanding Common Stock (an "Acquiring Person").
 
     Shares of Series B Preferred Stock purchasable upon exercise of the Rights
will not be redeemable. Each share of Series B Preferred Stock will be entitled,
when, as and if declared, to a minimum preferential quarterly dividend payment
of $1 per share but will be entitled to an aggregate dividend of 100 times the
dividend declared per share of Common Stock. In the event of liquidation, the
holders of the Series B Preferred Stock will be entitled to a minimum
preferential liquidation payment of $100 per share (plus any accrued but unpaid
dividends) but will be entitled to an aggregate payment of 100 times the payment
made per share of Common Stock. Each share of Series B Preferred Stock will have
100 votes, voting together with the Common Stock. Finally, in the event of any
merger, consolidation or other transaction in which shares of Common Stock are
converted or exchanged, each share of Series B Preferred Stock will be entitled
to receive 100 times the amount received per share of Common Stock. These rights
are protected by customary antidilution provisions.
 
                                       23
<PAGE>   26
 
     At any time prior to the time an Acquiring Person becomes such, the Board
of Directors of the Company may redeem the Rights in whole, but not in part, at
a price of $.01 per Right (the "Redemption Price"). The redemption of the Rights
may be made effective at such time, on such basis and with such conditions as
the Board of Directors in its sole discretion may establish. Immediately upon
any redemption of the Rights, the right to exercise the Rights will terminate
and the only right of the holders of Rights will be to receive the Redemption
Price.
 
     For so long as the Rights are then redeemable, the Company may, except with
respect to the Redemption Price, amend the Rights in any manner. After the
Rights are no longer redeemable, the Company may, except with respect to the
Redemption Price, amend the Rights in any manner that does not adversely affect
the interests of holders of the Rights.
 
     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.
 
     Miscellaneous.  The issued and outstanding shares of Common Stock are fully
paid and nonassessable. Holders of shares of Common Stock are not entitled to
preemptive rights. Shares of Common Stock are not convertible into shares of any
other class of capital stock. ChaseMellon Shareholder Services LLC is the
transfer agent, registrar and dividend disbursement agent for the Common Stock.
 
                              PLAN OF DISTRIBUTION
 
     Phillips and/or a Phillips Capital Trust may sell the Offered Securities in
any of, or any combination of, the following ways: (i) directly to purchasers,
(ii) through agents, (iii) through underwriters, and (iv) through dealers.
 
     Offers to purchase Offered Securities may be solicited directly by Phillips
and/or any Phillips Capital Trust, as the case may be, or by agents designated
by Phillips and/or any Phillips Capital Trust, as the case may be, from time to
time. Any such agent, who may be deemed to be an underwriter as that term is
defined in the Securities Act of 1933, involved in the offer or sale of the
Offered Securities in respect of which this Prospectus is delivered will be
named, and any commissions payable by Phillips to such agent will be set forth,
in the Prospectus Supplement. Unless otherwise indicated in the Prospectus
Supplement, any such agency will be acting in a best efforts basis for the
period of its appointment (ordinarily five business days or less). Agents,
dealers and underwriters may be customers of, engage in transactions with, or
perform services for the Company in the ordinary course of business.
 
     If an underwriter or underwriters are utilized in the sale, Phillips will
execute an underwriting agreement with such underwriters at the time of sale to
them and the names of the underwriters and the terms of the transaction will be
set forth in the Prospectus Supplement, which will be used by the underwriters
to make releases of the Offered Securities in respect of which this Prospectus
is delivered to the public.
 
     If a dealer is utilized in the sale of the Offered Securities in respect of
which this Prospectus is delivered, Phillips and/or any Phillips Capital Trust,
as the case may be, will sell such Offered Securities to the dealer, as
principal. The dealer may then resell such Offered Securities to the public at
varying prices to be determined by such dealer at the time of resale. The name
of the dealer and the terms of the transaction will be set forth in the
Prospectus Supplement.
 
     Agents, underwriters, and dealers may be entitled under the relevant
agreements to indemnification by Phillips and/or any Phillips Capital Trust, as
the case may be, against certain liabilities, including liabilities under the
Securities Act of 1933.
 
     The place and time of delivery for the Offered Securities in respect of
which this Prospectus is delivered are set forth in the accompanying Prospectus
Supplement.

Securities) and certain matters relating thereto will be passed upon for
Phillips by Dale J. Billam, Senior Counsel of Phillips, and for the underwriters

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
if 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 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 $200 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.

          (1) To file, during any period in which offers or sales are being

     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

     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 Companies
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.

                  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 4.3 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

                         (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 4.3(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 4.3(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 4.3(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 4.3(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


                                     - 10 -

<PAGE>   13


                  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 4.3(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 4.3(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 4.3(a) is in effect.
                  Any repeal or modification of this Section 4.3(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 4.3(a).

                         (viii) For purposes of this Section 4.3(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 4.3(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 4.3(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 (i) the
Delaware Trustee, (ii) any Affiliate of the Delaware Trustee, and (iii) any
officers, directors, shareholders, members, partners, employees,
representatives, nominees, custodians or agents of the Delaware





                                     - 11 -

Trustee (each of the Persons in (i) through (iii) 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 of 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 4.3(b) shall survive the termination
of this Declaration.

                  Section 4.4 Outside Businesses

                  Any Covered Person, the Sponsor and the Delaware 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 or the Delaware Trustee shall be
obligated to present any particular investment or other opportunity to the Trust
even if such opportunity is of a character that, if presented to the Trust,
could be taken by the Trust, and any Covered Person, the Sponsor and the
Delaware 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 and the Delaware 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 may act on any committee or body of holders of, securities or other
obligations of the Sponsor or its Affiliates.

            Sponsor's charter or of the Trust's certificate of trust;

                  (iii) upon the entry of a decree of judicial dissolution of

successors and assigns, whether so expressed.

                  Section 5.6 Partial Enforceability

such provision to any Person or circumstance, shall be held invalid, the

                                 OTHERS


                 Section 4.1      Exculpation.

                          (d)     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 bylaw, except that an Indemnified Person shall be liable for any
such loss, damage or claim incurred by reason of such Indemnified Person's
negligence or willful misconduct with respect to such acts or omissions; and

                          (e)     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 4.2     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, 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 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 the relative interest of
each party (including its own interest) to





                                     - 8  -
<PAGE>   11
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;
and



                          (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 4.3      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

                          (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





                                     - 9  -
<PAGE>   12
                 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 4.3(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 4.3(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 4.3(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 4.3(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





                                    - 10  -
<PAGE>   13
                 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 4.3(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 4.3(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 4.3(a) is in effect.  Any repeal or modification of
                 this Section 4.3(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 4.3(a).

                          (viii)    For purposes of this Section 4.3(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 4.3(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
                 4.3(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 (i)
the Delaware Trustee, (ii) any Affiliate of the Delaware Trustee, and (iii) any
officers, directors, shareholders, members, partners, employees,
representatives, nominees, custodians or agents of the Delaware





                                    - 11  -

Trustee (each of the Persons in (i) through (iii) 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 of 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 4.3(b) shall survive the
termination of this Declaration.

                 Section 4.4      Outside Businesses.

                 Any Covered Person, the Sponsor and the Delaware 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 or the Delaware Trustee
shall be obligated to present any particular investment or other opportunity to
the Trust even if such opportunity is of a character that, if presented to the
Trust, could be taken by the Trust, and any Covered Person, the Sponsor and the
Delaware 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 and the Delaware 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 may act on any committee or body of holders of, securities or
other obligations of the Sponsor or its Affiliates.

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

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:

provided that such action does not adversely affect the interests of Holders;

applicable tax returns and tax information reports that are required to be

                 provided herein;
 
                      (iii)       possess Trust property for other than a Trust
                 purpose;

                 other than loans represented by the Debentures;

                      (v)         possess any power or otherwise act in such a
                 way as to vary the Trust assets or the terms of the Securities
                 in any way whatsoever;

                      (vi)        issue any securities or other evidences of
                 beneficial ownership of, or beneficial interest in, the Trust
                 other than the Securities; or

                      (vii)       other than as provided in this Amended and

                 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

                      (i)         establish and maintain a segregated

                 Account") in the





                                     - 15 -
<PAGE>   19



                 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 Action") on or after the respective due date specified in the
Debentures. In connection with such Direct





                                     - 16 -
<PAGE>   20



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





                                     - 17 -
<PAGE>   21



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
                 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

                 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

                 Trustees or the Sponsor with their respective duties under
                 this Declaration, nor shall the Institutional Trustee be
                 liable for default or misconduct of the Regular Trustees or
                 the Sponsor.

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

                      (ii)        any direction or act of the Sponsor or the
                 Regular Trustees contemplated by this Declaration shall be
                 sufficiently evidenced by a Direction or an Officers'
                 Certificate;

                      (iii)       whenever in the administration of this
                 Declaration,  the Institutional Trustee shall deem it
                 desirable that a 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
                 its part, request and conclusively rely upon an Officers'
                 Certificate which, upon receipt of such request, shall be
                 promptly delivered by the Sponsor or the Regular Trustees;

                      (iv)        the Institutional Trustee shall have no duty
                 to see to any recording, filing or registration of any
                 instrument (including any financing or continuation statement
                 or any filing under tax or securities laws) or any
                 rerecording, refiling or registration thereof;

                      (v)         the Institutional Trustee may consult with
                 counsel or other experts and the advice or opinion of such
                 counsel and experts with respect to legal matters or advice
                 within the scope of such experts' area of expertise 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 Sponsor or any of its
                 Affiliates, and may include any of its employees. The
                 Institutional Trustee shall have the right at any time to seek
                 instructions concerning the administration of this Declaration
                 from any court of competent jurisdiction;

                      (vi)        the Institutional Trustee shall be under no
                 obligation to exercise any of the rights or powers vested init
                 by this Declaration at the request or direction of any Holder,
                 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 Default, of its obligation to
                 exercise the rights and powers vested in it by this
                 Declaration;

                      (vii)       the Institutional Trustee shall not be bound
                 to make any investigation into the facts or matters stated in
                 any resolution, certificate, statement, instrument, opinion,
                 report, notice, request, direction, consent, order, bond,
                 debenture, note, other evidence of indebtedness or other paper
                 or document, but the 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 or powers hereunder or perform any duties hereunder
                 either directly or by or through agents, custodians, nominees
                 or attorneys and the Institutional 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 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 remedy, right or action, (ii) may refrain from
                 enforcing such remedy or right or taking such other action
                 until such instructions are received, and (iii) shall be
                 protected in conclusively relying on or acting in or
                 accordance with such instructions; and

                      (xi)        except as otherwise expressly provided by
                 this Declaration, the Institutional Trustee shall not be under
                 any obligation to take any action that is discretionary under
                 the 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,





                                     - 21 -

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

Trustee is authorized to execute on behalf of the Trust any documents that the
Regular Trustees have the power and authority to execute pursuant to Section
3.6; provided that, the registration statement referred to in Section
3.6(b)(i), including any amendments thereto, shall be signed by all of 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
any responsibility for their correctness. The Trustees make no representations
as to the value or 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

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





                                     - 22 -
<PAGE>   26



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;

                      (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





                                     - 23 -
<PAGE>   27



   (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.

Preferred Securities;

                          (d)     to prepare for filing by the Trust with the

Securities, the Sponsor may, by written instrument, increase or decrease the
number of Trustees; and

                          (b)     after the issuance of any Securities, the

provided that, if the Institutional Trustee has its principal place of business
in the State of Delaware and otherwise meets the requirements of applicable

Section 3.11 shall have no application.

                 Section 5.3      Institutional Trustee; Eligibility.

                      (a)         There shall at all times be one Trustee which

                 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 of such
                 corporation shall be deemed to be its combined capital and

                 published.

                          (b)     If at any time the Institutional Trustee

acquire any "conflicting interest" within the meaning of Section  310(b) of the
Trust Indenture Act, the Institutional Trustee and the Holder of the Common
Securities (as if it were the obligor referred to in Section  310(b) of the
Trust Indenture Act) shall in all respects comply with the provisions of
Section  310(b) of the Trust Indenture Act.

                          (d)     The Preferred Securities Guarantee shall be

                 Trustee shall not be removed in accordance with Section 5.7(a)

                 by such Successor Institutional Trustee and delivered to the

                      (ii)        the Trustee that acts as Delaware Trustee
                 shall not be removed in accordance with this Section 5.7(a)

                 appointment by instrument executed by such Successor Delaware

                          (d)     The Holders of the Common Securities shall

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,
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.

                 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

the Regular Trustees or any

committee 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.

                          (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, 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

                 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 Declaration
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.

                 days after the date of revocation without a reinstatement
                 thereof;

                 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

                             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.

                          (b)     Subject to this Article IX, Preferred

                          (c)     The Sponsor may not transfer the Common

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 Preferred Security Certificate
representing such Preferred Security Beneficial Owner's interests in such
Global Certificates, 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

                          (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.

                 Section 10.1     Liability.

                          (a)     Except as expressly set forth in this
Declara- tion, 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; an

                      (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.

                      (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 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,





                                     - 37 -
<PAGE>   41



                 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.

                      (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





                                     - 38 -
<PAGE>   42



                 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 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).





                                     - 39 -
<PAGE>   43



                 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

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

                 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
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.

                          (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

                      (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

                 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 _______, 1998 (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 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 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





                                     - 1 -
<PAGE>   56



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 ________, 1998, and will be payable quarterly in
arrears, on [March 31, June 30, September 30, and December 31] of each year,
commencing on _______, 1998, 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 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 ______, 1998, to the Prospectus
dated ______, 1998 (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





                                     - 2 -
<PAGE>   57



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 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.





                                     - 3 -
<PAGE>   58




                          (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 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





                                     - 4 -

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 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 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 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 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





                                     - 8 -

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 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)

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

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 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.

                 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

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.

to subscribe for any additional securities.

                          13.     Miscellaneous.

                 These terms constitute a part of the Declaration.

                 The Sponsor will provide a copy of the Declaration, the

                     FORM OF PREFERRED SECURITY CERTIFICATE

                 This Preferred Security is a Global Certificate within the
meaning of the Declaration hereinafter referred to and is registered in the
name of The Depository Trust Company (the "Depositary") or a nominee of the
Depositary. This Preferred Security is exchangeable for Preferred Securities
registered in the name of a person other than the Depositary or its nominee

of this Preferred Security (other than a transfer of this Preferred Security as
a whole 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) may be

representative of The Depository Trust Company (55 Water Street, New York, New
York) to the Trust or its agent for registration of transfer, exchange or
payment, and any Preferred Security issued is registered in the name of Cede &
Co. or such other name as requested by an authorized representative of The
Depository Trust Company and any payment hereon is made to Cede & Co., ANY

                         [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 ________, 1998, 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.

                 The Preferred Securities shall be redeemable as provided in 
the Declaration.

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.

                          (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

                 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

                          (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 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.

                 income tax purposes the Trust will not be classified as a
                 grantor trust.

                          (c)     The Institutional Trustee shall:

                          (i)     establish and maintain a segregated
                 non-interest bearing trust account (the "Institutional Trustee
                 Account") 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 Action") on or after the respective due date specified in the
Debentures. In connection with such Direct





                                     - 16 -
<PAGE>   20



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





                                     - 17 -
<PAGE>   21



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
                 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





                                     - 18 -

                 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 default or misconduct of the Regular Trustees or
                 the Sponsor.

                 Section 3.10     Certain Rights of Institutional Trustee.

                          (a)     Subject to the provisions of Section 3.9:

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

                          (ii)    any direction or act of the Sponsor or the
                 Regular Trustees contemplated by this Declaration shall be
                 sufficiently evidenced by a Direction or an Officers'
                 Certificate;

                          (iii)   whenever in the administration of this
                 Declaration,  the Institutional Trustee shall deem it
                 desirable that a 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
                 its part, request and conclusively rely upon an Officers'
                 Certificate which, upon receipt of such request, shall be
                 promptly delivered by the Sponsor or the Regular Trustees;

                          (iv)    the Institutional Trustee shall have no duty
                 to see to any recording, filing or registration of any
                 instrument (including any financing or continuation statement
                 or any filing under tax or securities laws) or any
                 rerecording, refiling or registration thereof;

                          (v)     the Institutional Trustee may consult with
                 counsel or other experts and the advice or opinion of such
                 counsel and experts with respect to legal matters or advice
                 within the scope of such experts' area of expertise 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 Sponsor or any of its
                 Affiliates, and may include any of its employees. The
                 Institutional Trustee shall have the right at any time to seek
                 instructions concerning the administration of this Declaration
                 from any court of competent jurisdiction;

                          (vi)    the Institutional Trustee shall be under no
                 obligation to exercise any of the rights or powers vested init
                 by this Declaration at the request or direction of any Holder,
                 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 Default, of its obligation to
                 exercise the rights and powers vested in it by this
                 Declaration;





                                     - 20 -

                          (vii)   the Institutional Trustee shall not be bound
                 to make any investigation into the facts or matters stated in
                 any resolution, certificate, statement, instrument, opinion,
                 report, notice, request, direction, consent, order, bond,
                 debenture, note, other evidence of indebtedness or other paper
                 or document, but the 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 or powers hereunder or perform any duties hereunder
                 either directly or by or through agents, custodians, nominees
                 or attorneys and the Institutional 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 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 remedy, right or action, (ii) may refrain from
                 enforcing such remedy or right or taking such other action
                 until such instructions are received, and (iii) shall be
                 protected in conclusively relying on or acting in or
                 accordance with such instructions; and

                          (xi)    except as otherwise expressly provided by
                 this Declaration, the Institutional Trustee shall not be under
                 any obligation to take any action that is discretionary under
                 the 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,





                                     - 21 -

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.

                 Notwithstanding any other provision of this Declaration other
than Section 5.2, the Delaware Trustee shall not be entitled to exercise any
powers, nor shall the Delaware Trustee have any of the duties and

in this Declaration. Except as set forth in Section 5.2, the Delaware Trustee
shall be a Trustee for the sole and limited purpose of fulfilling the
requirements of Section  3807 of the Business Trust Act.

except as otherwise required by the Business Trust Act, a majority of or, if
there are only two, any Regular Trustee or, if there is only one, such Regular
Trustee is authorized to execute on behalf of the Trust any documents that the
Regular Trustees have the power and authority to execute pursuant to Section
3.6; provided that, the registration statement referred to in Section
3.6(b)(i), including any amendments thereto, shall be signed by all of the
Regular Trustees.

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 condition of the property of the Trust or any part thereof.

                 The Trust, unless terminated pursuant to the provisions of

                 Section 3.15     Mergers.

                          (a)     The Trust may not consolidate, amalgamate,

properties and assets substantially as an entirety to any corporation or other

                          (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;

                          (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





                                     - 23 -
<PAGE>   27



   (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.

or the Nasdaq National Market for listing upon notice of issuance of any
Preferred Securities;

                          (d)     to prepare for filing by the Trust with the

                          (b)     after the issuance of any Securities, the
number of Trustees may be increased or decreased by vote of the Holders of a
majority in liquidation amount of the Common Securities voting as a class at a
meeting of the Holders of the Common Securities; provided, however, that, the
number of Trustees shall in no event be less than two (2); provided further

                 institutional trustee under the Trust Indenture Act,
                 authorized under such laws to exercise corporate trust powers,
                 having a combined capital and surplus of at least 50 million

                 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 supervising or examining authority
                 referred to above, then for the purposes of this Section
                 5.3(a)(ii), the combined capital and surplus of such
                 corporation shall be deemed to be its combined capital and

                 published.

                          (b)     If at any time the Institutional Trustee

acquire any "conflicting interest" within the meaning of Section  310(b) of the
Trust Indenture Act, the Institutional Trustee and the Holder of the Common
Securities (as if it were the obligor referred to in Section  310(b) of the

                 Trustee shall not be removed in accordance with Section 5.7(a)
                 until a Successor Institutional Trustee has been appointed and
                 has accepted such appointment by written instrument executed
                 by such Successor Institutional Trustee and delivered to the

                          (ii)    the Trustee that acts as Delaware Trustee
                 shall not be removed in accordance with this Section 5.7(a)
                 until a successor Trustee possessing the qualifications to act
                 as Delaware Trustee under Sections 5.2 and 5.4 (a "Successor
                 Delaware Trustee") has been appointed and has accepted such

                 Delaware Trustee and delivered to the Regular Trustees and the
                 Sponsor.

                          (c)     A Trustee appointed to office shall hold
office until his successor shall have been appointed or until his death,
removal or resignation. Any Trustee may resign from office (without need for

provided, however, that:

                 appointment by instrument executed by such Successor Delaware

                          (d)     The Holders of the Common Securities shall
use their best efforts to promptly appoint a Successor Delaware Trustee or
Successor Institutional Trustee as the case may be if the Institutional Trustee
or the Delaware Trustee delivers an instrument of resignation in accordance
with this Section 5.7.

                          (e)     If no Successor Institutional Trustee or
Successor Delaware Trustee shall have been appointed and accepted appointment
as provided in this Section 5.7 within 60 days after delivery to the Sponsor
and the Trust 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,
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.

                 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





                                     - 29 -
<PAGE>   33

committee 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,

                                   ARTICLE VI
                                 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 Declaration
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.

                 days after the date of revocation without a reinstatement
                 thereof;

                          (iii)   upon the entry of a decree of judicial

                          (iv)    when all of the Securities shall have been

                 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

                          (b)     As soon as is practicable after the

                             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.

                          (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

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

duly executed by the Holder or such Holder's attorney duly authorized in





                                     - 33 -

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.

                 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 Preferred Security Certificate
representing such Preferred Security Beneficial Owner's interests in such
Global Certificates, 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

                          (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.

Declara- tion, the Securities Guarantees and the terms of the Securities, the

                          (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; an

                          (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

                 Section 10.2     Exculpation.

                          (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

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,

                          (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 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,

<PAGE>   41



                 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.

                          (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 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





                                     - 40 -

                 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 present any particular investment or other opportunity to the Trust even if
such opportunity is of a character that, if presented to the Trust, could be
taken by the Trust, and 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
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.

                          (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

                 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

                                    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 _______, 1998 (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 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 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





                                     - 1 -
<PAGE>   56



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 ________, 1998, and will be payable quarterly in
arrears, on [March 31, June 30, September 30, and December 31] of each year,
commencing on _______, 1998, 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 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 ______, 1998, to the Prospectus
dated ______, 1998 (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





                                     - 2 -

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 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.





                                     - 3 -
<PAGE>   58



                          (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 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





                                     - 4 -

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 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."

<PAGE>   60



                          (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 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





                                     - 6 -
<PAGE>   61

                 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 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





                                     - 7 -

                 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 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





                                     - 8 -
<PAGE>   63

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 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





                                     - 9 -
<PAGE>   64



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 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.

to subscribe for any additional securities.

                          13.     Miscellaneous.

                 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
appropriate), and the Indenture to a Holder without charge on written request
to the Sponsor at its principal place of business.

                         [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 ________, 1998, 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.

                 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

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,

Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any

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

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

Preferred Securities Guarantee, but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon.

SECTION 2.7               Event of Default; Notice

                          (a)     The Preferred Guarantee 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 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

                          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

                          (c)      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)     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.

SECTION 3.2               Certain Rights of Preferred Guarantee Trustee

                          (a)     Subject to the provisions of Section 3.1:

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

                                  (ii)     Any direction or act of the
Guarantor contemplated by this Preferred Securities Guarantee shall be
sufficiently evidenced by an Officers' Certificate.

                                  (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 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 rerecording, refiling or registration thereof).

                                  (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





                                     - 8 -
<PAGE>   12
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 make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of
indebtedness or other paper or document, but the Preferred Guarantee Trustee,
in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit.

                                  (viii) The Preferred Guarantee Trustee may
execute any of 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

                                  (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 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.

                          (b)     If at any time the Preferred Guarantee
Trustee shall cease to be eligible to so act under Section 4.1(a), the

                          (b)      The Preferred Guarantee Trustee shall not be
removed in accordance with Section 4.2(a) until a Successor Preferred Guarantee

to the Guarantor.

                          (c)     The Preferred Guarantee Trustee appointed to

Preferred Guarantee Trustee and delivered to the Guarantor and the resigning
Preferred Guarantee Trustee.

                          (d)     If no Successor Preferred Guarantee Trustee
shall have been appointed and accepted appointment as provided in this Section
4.2 within 60 days after delivery to the Guarantor of an instrument of removal
or resignation, the resigning Preferred Guarantee Trustee may petition any

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

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)     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)     failure, omission, delay or lack of diligence

extension of any kind;

                          (d)     voluntary or involuntary liquidation,

guaranteed hereby or hereby incurred; or

                          (g)     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.

                          (a)     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)     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,

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.

distribution of the Debentures to the Holders of all of the Preferred
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.

in it by this Preferred Securities Guarantee, and use the same degree of care

under the circumstances in the conduct of his or her own affairs.

                          (d)     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

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

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

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

Securities Guarantee shall require the Preferred Guarantee Trustee to expend or
risk its own funds or otherwise incur personal financial liability in the

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 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

consult with counsel, and the written advice or opinion of such counsel with
respect to legal matters shall be full and complete authorization and

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

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 the Preferred Guarantee Trustee's or its
agent's taking such action.

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

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

                          (b)      The Preferred Guarantee Trustee shall not be

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

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;

extension of the maturity date of the Debentures permitted by the Indenture);

                          (c)     failure, omission, delay or lack of diligence

extension of any kind;

                          (d)     voluntary or involuntary liquidation,

guaranteed hereby or hereby incurred; or

                          (g)     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.

under this Preferred Securities Guarantee.

                          (b)     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,

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.

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.

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.

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.

Company, and Phillips 66 Capital III, Phillips 66 Capital IV, Phillips 66
Capital V and Phillips 66 Capital VI, each a statutory business trust created

the Securities and Exchange Commission (the "Commission") under the Securities
Act of 1933, as amended (the "Act"), of a Registration Statement on Form S-3
(the "Registration Statement"), relating to registration under the Act of (i)

National Association (the "Senior Debt Trustee"), as trustee (as amended or
supplemented, the "Senior Debt Indenture"), a Subordinated Debt Indenture dated
as of May 23, 1996 between Phillips and The Bank of New York (the "Subordinated
Debt Trustee" and, together with the Senior Debt Trustee, the "Trustee"), as
trustee (as amended or supplemented, the "Subordinated Debt Indenture" and,
together with the Senior Indenture, the "Indenture"), (ii) shares of preferred
stock, with or without par value (the "Preferred Stock") of Phillips, which may
be represented by depositary shares (the "Depositary Shares") evidenced by
depositary receipts (the "Receipts"); (iii) shares of Common Stock, $1.25 par
value per share, of Phillips (the "Common Stock"); (iv) stock purchase or

to be issued by the Trusts, as described below.

                 I will also act as counsel to Phillips and the Trusts in
connection with offerings from time to time of Preferred Securities of the

Registration Statement.  The Preferred Securities are to be issued by each
Trust pursuant to an Amended and Restated Declaration of Trust (the "Amended

incorporated by reference as exhibits to the Registration Statement.

                 I have examined originals or copies, certified or otherwise
identified to my satisfaction, or such documents, corporate records,

exchange or conversion of any shares of Preferred Stock that are exchangeable
or convertible into Debt Securities or (y) as part of Stock Purchase Units)
will constitute valid and binding obligations of Phillips, enforceable against
Phillips in accordance with their terms, except

                 Re:      The Phillips Capital Trusts (as defined below)

Ladies and Gentlemen:

                 We have acted as special Delaware counsel to Phillips 66
Capital III, Phillips 66 Capital IV, Phillips 66 Capital V and Phillips 66
Capital VI, each a Delaware statutory business trust (collectively referred to
herein as the "Phillips Capital Trusts" and each individually as a "Phillips

                 In rendering this opinion, we have examined copies of the
following documents in the forms provided to us:  the Certificates of Trust of
Phillips 66 Capital III and Phillips 66 Capital IV, each as filed in the Office
of the Secretary of the State of Delaware (the "State Office") on February 23,

Bank of New York, as Trustee, and the First Supplemental Indenture dated as of

entered into in connection therewith; the form of Preferred Securities
Guarantee to be made by the Company with respect to each Phillips Capital Trust
(the form of Preferred Securities Guarantee of each Phillips Capital Trust is
referred to herein as a "Guarantee Agreement"); the form of Underwriting
Agreement relating to the Preferred Securities to be entered into between the
Company, on its own behalf and on behalf of each Phillips Capital Trust, and
Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated as
representative of the several underwriters named in Schedule A thereto (the
"Underwriting Agreement"); the Registration Statement; and a certification of
good standing of each Phillips Capital Trust obtained as of a recent date from
the State Office.  In such examinations, we have assumed the genuineness of all
signatures, the conformity to original documents of all documents submitted to
us as drafts or copies or forms of documents to be executed and the legal
capacity of natural persons to complete the execution of documents.  We have
further assumed for purposes of this opinion:  (i) the due formation,
organization or creation, valid existence and good standing of the Phillips
Capital Trusts and each entity that is a party to any of the documents reviewed
by us under the laws of the jurisdiction of its respective formation,
organization or creation; (ii) the due authorization, execution and delivery
by, or on behalf of, each of the parties thereto of the above referenced
documents with respect to each Phillips Capital Trust; (iii) that the Company,
The Bank of New York, The Bank of New York (Delaware) and the appropriate
Regular Trustees will duly authorize, execute and deliver the applicable
Governing Instrument, the Underwriting Agreement and all other documents
contemplated thereby or by the Registration Statement to be executed in
connection with the issuance by each Phillips Capital Trust of Preferred
Securities, in each case prior to the first issuance of Preferred Securities of
such Phillips Capital Trust; (iv) that the Preferred Securities of each
Phillips Capital Trust will be offered and sold pursuant to a prospectus and a
prospectus supplement thereto (collectively, the "Prospectus") forming a part
of the Registration Statement that will be consistent with, and accurately
describe, the terms of the applicable Governing Instrument and the applicable
Guarantee Agreement relating to each such Phillips Capital Trust and all other
relevant documents; (v) that no event has occurred or will occur subsequent to
the filing of any Certificate that would cause a dissolution or liquidation of
any Phillips Capital Trust under the applicable Original Governing Instrument
or the applicable Governing Instrument; (vi) that the activities of each
Phillips Capital Trust have been and will be

conducted in accordance with its Original Governing Instrument or Governing
Instrument, as applicable, and the Delaware Business Trust Act, 12 Del. C.
Sections  3801 et seq. (the "Delaware Act"); (vii) that each Holder of
Preferred Securities of each Phillips Capital Trust will make payment of the
required consideration therefor and receive a Preferred Securities Certificate
in consideration thereof in accordance with the terms and conditions of the
applicable Governing Instrument, the Registration Statement, the applicable
prospectus supplement and the Underwriting Agreement, and that the Preferred
Securities of each Phillips Capital Trust are otherwise issued and sold to the
Preferred Securities Holders of such Phillips Capital Trust in accordance with
the terms, conditions, requirements and procedures set forth in the applicable
Governing Instrument, the Registration Statement, the applicable prospectus
supplement and the Underwriting Agreement; and (viii) that the documents
examined by us, or contemplated hereby, express the entire understanding of the
parties thereto with respect to the subject matter thereof and have not been,
and, prior to the issuance of Preferred Securities by each Phillips Capital
Trust, will not be, amended, supplemented or otherwise modified, except as
herein referenced.  No opinion is expressed with respect to the requirements
of, or compliance with, federal or state securities or blue sky laws.  Further,
we express no opinion with respect to the Registration Statement or any other
offering materials relating to the Preferred Securities offered by any Phillips
Capital Trust and we assume no responsibility for their contents.  As to any
fact material to our opinion, other than those assumed, we have relied without
independent investigation on the above referenced documents and on the
accuracy, as of the date hereof, of the matters therein contained.

                 Based on and subject to the foregoing, and limited in all
respects to matters of Delaware law, it is our opinion that, upon issuance, the
Preferred Securities of each Phillips Capital Trust will constitute validly
issued and, subject to the terms of the applicable Governing Instrument, fully
paid and non-assessable beneficial interests in the assets of such Phillips
Capital Trust.  We note that pursuant to each Governing Instrument, each
Phillips Capital Trust may withhold amounts otherwise distributable to a Holder
of Securities in such Phillips Capital Trust and pay over such amounts to the
applicable jurisdictions in accordance with federal, state and local law and
any amounts withheld will be deemed to have been distributed to such Holder and
that, pursuant to the Governing Instrument, the Preferred Security Holders of
each Phillips Capital Trust may be obligated to make payments or provide
indemnity or security under the circumstances set forth therein.

                 We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the use of our name under the heading
"LEGAL MATTERS" in the Prospectus forming a part thereof.  In giving this
consent, we do not thereby admit that we come 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 thereunder.  This
opinion speaks only as of the date hereof and is based on our understandings
and assumptions as to present facts, and our review of the above referenced
documents and the application of Delaware law as the same exist on the date
hereof, and we undertake no obligation to update or supplement this opinion
after the date

circumstances that may hereafter come to our attention or any changes in facts
