Prepayment/Redemption:                  The Trust Property is subject to
                                        redemption at any time and is subject to
                                        call in accordance with Schedule III.

                                        If there is a partial redemption of the
                                        Securities or a related partial exercise
                                        of the Call Option Swap Agreement, the
                                        Trustee will randomly select Units to be
                                        redeemed in full from the proceeds of
                                        such partial exercise of the Call Option
                                        Swap Agreement or partial redemption of
                                        the Securities. The proceeds of any such
                                        call or redemption shall be distributed
                                        upon the Distribution Date corresponding
                                        to such call or redemption.

                                        If any exercise of less than all Call
                                        Option Swap Agreements occurs while
                                        multiple Call Option Swap Agreements are
                                        outstanding, the Trustee will randomly
                                        select Units to be redeemed from the
                                        proceeds of such exercise.

                                        If any partial redemption of the
                                        Securities held by the Trust occurs
                                        while multiple Interest Rate Swap
                                        Agreements are outstanding, the Trustee
                                        will randomly assign the portion of such
                                        partial redemption that shall be deemed
                                        to occur under each of such Interest
                                        Rate Swap Agreements.

Additional Distribution:                If any of the Securities are redeemed by
                                        the Security Issuer prior to July 10,
                                        2006, each of the Units which are
                                        redeemed in connection with such
                                        redemption of Securities will receive a
                                        pro rata distribution from the proceeds
                                        of the redemption of the Securities
                                        remaining after payment of principal and
                                        interest on such Units up to a maximum

                                        Agreement relating to the insolvency or
                                        bankruptcy of the Security Issuer.

Sale of Securities                      If the Trust must sell the Securities it
                                        holds, the Trust will sell the
                                        Securities through the Selling Agent in
                                        accordance with Section 9.03(b) and the
                                        following terms. The Selling Agent will
                                        solicit bids for all of the Securities
                                        held by the Trust from at least three
                                        registered broker-dealers of national
                                        reputation, one of which shall be the
                                        Selling Agent. The Selling Agent will,
                                        on behalf of the Trust, sell the
                                        Securities at the highest bid price
                                        received. If the Selling Agent did not
                                        put forward such highest bid, it may
                                        purchase the Securities at such highest
                                        bid rather than selling the Securities
                                        to the highest bidder.

Voting and other Actions:               In the event that the Security Issuer
                                        solicits any vote (other than a
                                        self-tender), consent, waiver,
                                        modification or other action under the
                                        Security Agreement or the terms of the
                                        Securities, the Trustee will act with
                                        respect to all of the Securities in
                                        conformity with the direction of a
                                        majority (by outstanding Unit Principal
                                        Balance) of the Units.

Additional Issuance of Units:           Upon no less than 5 days' notice to the
                                        Trustee, the Depositor may deposit
                                        additional Securities at any time in
                                        exchange for additional Units in a
                                        minimum aggregate amount of $250,000
                                        and, if in excess of such amount, in a
                                        $25 integral multiple in excess thereof.
                                        The principal amount of Securities
                                        deposited must be in the same ratio to
                                        the Unit Principal Balance of the Units
                                        received as the ratio of the aggregate
                                        Unit Principal Balance on the Closing
                                        Date to the aggregate principal balance
                                        of the Securities on the Closing Date.
                                        The Depositor must either arrange for
                                        the Swap Counterparty and the Trust to
                                        increase proportionally the notional
                                        amount under the Swap Agreement or
                                        arrange for an additional Swap Agreement
                                        to be entered into between the Trust and
                                        an additional Swap Counterparty. The
                                        Rating Agency Condition must be
                                        satisfied in connection with any such
                                        additional issuance.

establishes to the satisfaction of the Trustee the pledgee's right so to act
with respect to such Securities and that the pledgee is not the Company, the
Guarantor or any other obligor upon the Securities or any Affiliate of the

and opinions as may be required under the Trust Indenture Act. Each such

condition or covenant provided for in this Indenture shall include

SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

          Any certificate or opinion of an officer of the Company or the
Guarantor may be based, insofar as it relates to legal matters, upon a
certificate or opinion of, or representations by, counsel, unless such officer
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to the matters upon which his
certificate or opinion is based are erroneous. Any such certificate or opinion
of counsel may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Company or of the Guarantor, as the case may be, stating that the information
with respect to such factual matters is in the possession of the Company or of
the Guarantor, as the case may be, unless such counsel knows, or in the exercise
of reasonable care should know, that the certificate or opinion or
representations with respect to such matters are erroneous.

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 104. ACTS OF HOLDERS; RECORD DATES.

waiver or other action provided

                                      -14-
<PAGE>

by this Indenture to be given or taken by Holders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Holders in person or by agent duly appointed in writing; and, except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Company and the Guarantor. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 701) conclusive in favor of the Trustee and the Company
and the Guarantor, if made in the manner provided in this Section.

          (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

          (c) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Outstanding Securities entitled to give, make or take any request,
demand, authorization, direction, notice, consent, waiver or other action
provided or permitted by this Indenture to be given, made or taken by Holders of
Securities, PROVIDED that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next
paragraph. If not set by the Company prior to the first solicitation of a Holder
made by any Person in respect of any such matter referred to in the foregoing
sentence, the record date for any such matter shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 801) prior to such first solicitation. If any record date is
set pursuant to this paragraph, the Holders of Outstanding Securities on such
record date, and no other Holders, shall be entitled to take the relevant
action, whether or not such Holders remain Holders after such record date;
PROVIDED that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities on

                                      -15-
<PAGE>

such record date. Nothing in this paragraph shall be construed to prevent the
Company from setting a new record date for any action for which a record date
has previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person be canceled
and of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder of Securities in the manner set forth in Section 106.

          The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to join in the giving
or making of (i) any Notice of Default, (ii) any request to institute
proceedings referred to in Section 607(2) or (iii) any direction referred to in
Section 612. If any record date is set pursuant to this paragraph, the Holders
of Outstanding Securities on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; PROVIDED that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities on such record date. Nothing in this paragraph shall be construed to
prevent the Trustee from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Company's expense, shall cause notice of such record date, the proposed action
by Holders and the applicable Expiration Date to be given to the Company in
writing and to each Holder of Securities in the manner set forth in Section 106.

                                      -16-
<PAGE>

          With respect to any record date set pursuant to this Section, the
party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; PROVIDED that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Securities in the manner set forth in Section
106, on or prior to the existing Expiration Date. If an Expiration Date is not
designated with respect to any record date set pursuant to this Section, the
party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

          Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

          (d) The ownership of Securities shall be proved by the Security
Register.

          (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company or the Guarantor in reliance thereon, whether or not notation of such
action is made upon such Security.

SECTION 105. NOTICES, ETC., TO TRUSTEE, COMPANY, AND GUARANTOR.

          Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

                    (1) the Trustee by any Holder or by the Company or the
          Guarantor shall be sufficient for every purpose hereunder if made,
          given, furnished or filed in writing to

                                      -17-
<PAGE>

          or with the Trustee at its Corporate Trust Office, Attention:
          Corporate Trust Administration, or

                    (2) the Company or the Guarantor by the Trustee or by any
          Holder shall be sufficient for every purpose hereunder (unless
          otherwise herein expressly provided) if in writing and mailed,
          first-class postage prepaid, to the Company or the Guarantor, as the
          case may be, addressed to it at the address of its principal office
          specified in the first paragraph of this instrument or at any other
          address previously furnished in writing to the Trustee by the Company
          or the Guarantor.

SECTION 106. NOTICE TO HOLDERS; WAIVER.

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

          In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

          If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this

                                      -18-
<PAGE>

Indenture, the latter provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.

SECTION 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

          The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

SECTION 109. SUCCESSORS AND ASSIGNS.

          All covenants and agreements in this Indenture by the Company and the
Guarantor shall bind their respective successors and assigns, whether so
expressed or not.

SECTION 110. SEPARABILITY CLAUSE.

          In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

shall give to any Person, other than (a) the parties hereto and their successors
hereunder, (b) the holders of Senior Indebtedness, (c) the Holders of Securities
and (d) subject to Section 1007, the creditors in respect of General
Obligations, any benefit or any legal or equitable right, remedy or claim under

and construed in accordance with the laws of the State of New York.

SECTION 113. LEGAL HOLIDAYS.

          Except as otherwise specified in Section 202, in any case where any
Interest Payment Date, Redemption Date or Stated Maturity of any Security shall
not be a Business Day, then (notwithstanding any other provision of this

                                      -19-
<PAGE>

Indenture or of the Securities or Guarantees) payment of interest or principal
(and premium, if any) need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, PROVIDED
that no interest shall accrue for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be.

No. __________                                                         $________

          ZIONS FINANCIAL CORP., a corporation duly organized and existing under
the laws of Delaware (herein called the "Company", which term includes any
successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to _________________, or registered assigns,
the principal sum of Two Hundred Million Dollars (such amount the "principal
amount" of this Security) [if the Security is a Global Security, then insert - -
or such other principal amount (which, when taken together with the principal
amounts of all other Outstanding Securities, shall not exceed $200,000,000 in
the aggregate at any one time) as may be set forth in the records of the trustee
hereinafter referred to in accordance with the Indenture,] on May 15, 2011, and
to pay interest thereon from May 24, 2001 or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, semi-annually
on May 15 and November 15 in each year, commencing November 15, 2001 until but
excluding May 15, 2006, at the rate of 6.95% per annum, and from May 15, 2006
until the principal hereof is paid or made available for payment (such date, the
"Principal Payment Date," and such period, the "Floating Rate Period"), at the
Floating Interest Rate.

          During the Floating Rate Period, the per annum interest rate on this
Security (the "Floating Interest Rate") in effect for each day of an Interest
Reset Period (as defined below) will be equal to LIBOR (as defined below) plus
286 basis points (2.86%), as determined by the Calculation Agent. The Floating
Interest Rate for each Interest Period will be set monthly on the first day of
each Interest Reset Period (as defined below) commencing May 15,

                                      -22-

<PAGE>

2006 (each such date, an "Interest Reset Date"). During the Floating Rate
Period, the amount of interest for each day this Security is outstanding (the
"Daily Interest Amount") shall be calculated by dividing the interest rate in
effect for that day by 360 and multiplying the result by the outstanding
principal amount of this Security. The amount of interest to be paid on this
Security for each Interest Reset Period shall be calculated by adding the Daily
Interest Amounts for each day in such Interest Reset Period.

          In the event that an Interest Payment Date is not a Business Day, the
Company shall pay interest on the next day that is a Business Day, with the same
force and effect as if made on the Interest Payment Date, and without any
interest or other payment with respect to the delay; PROVIDED, HOWEVER, if such
Interest Payment Date occurs during the Floating Rate Period and such next
Business Day is in a different month, then the Company shall pay interest on the
Business Day immediately preceding that Interest Payment Date for the entire
Interest Reset Period. If the Principal Payment Date or earlier Redemption Date
falls on a day that is not a Business Day, the payment of principal and
interest, if any, need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the
Principal Payment Date or earlier Redemption Date, PROVIDED that no interest
shall accrue for the period from and after such Principal Payment Date or
earlier Redemption Date.

          "LIBOR", with respect to an Interest Reset Period, shall be the rate
(expressed as a percentage per annum) for deposits in United States dollars for
a one-month period beginning on the second London Banking Day (as defined below)
after the Determination Date (as defined below) that appears on Telerate Page
3750 (as defined below) as of 11:00 a.m., London time, on the Determination
Date. If Telerate Page 3750 does not include this rate or is unavailable on the
Determination Date, the Calculation Agent will request the principal London
office of each of four major banks in the London interbank market, as selected
by the Calculation Agent, to provide that bank's offered quotation (expressed as
a percentage per annum) as of approximately 11:00 a.m., London time, on the
Determination Date to prime banks in the London interbank market for deposits in
a Representative Amount (as defined below) in United States dollars for a
one-month period beginning on the second London Banking Day after the
Determination Date. If at least two offered quotations are so provided, LIBOR
for the Interest Reset Period will be the arithmetic mean of those quotations.
If fewer than two quotations are so provided, the Calculation Agent will request
each of three major banks in New York

                                      -23-
<PAGE>

City, as selected by the Calculation Agent, to provide that bank's rate
(expressed as a percentage per annum), as of approximately 11:00 a.m., New York
City time, on the Determination Date for loans in a Representative Amount in
United States dollars to leading European banks for a one-month period beginning
on the second London Banking Day after the Determination Date. If at least two
rates are so provided, LIBOR for the Interest Reset Period shall be the
arithmetic mean of those rates. If fewer than two rates are so provided, then
LIBOR for the Interest Reset Period shall be LIBOR in effect with respect to the
immediately preceding Interest Reset Period or, in the case of the first
Interest Reset Period, the rate per annum on this Security when first issued
under the Indenture.

          "Determination Date" with respect to an Interest Reset Period shall be
the second London Banking Day preceding the first day of the Interest Reset
Period.

          "Interest Reset Period" shall mean each period, during the Floating
Rate Period, commencing on and including the fifteenth day of the month and
ending on and including the fourteenth day of the next succeeding month, and, in
the case of the last such period, commencing on and including the fifteenth day
of the month immediately preceding the Principal Payment Date, as the case may
be, to but not including the Principal Payment Date. The first Interest Reset
Period shall commence on and include May 15, 2006 and end on and include June
14, 2006.

          "London Banking Day" is any day in which dealings in the United States
dollars are transacted or, with respect to any future date, are expected to be
transacted in the London interbank market.

          "Representative Amount" means a principal amount that is
representative for a single transaction in the relevant market at the relevant
time.

          "Telerate Page 3750" means the display designated as "Page 3750" on
the Bridge Telerate Service (or such other page as may replace Page 3750 on that
service).

          All percentages resulting from any of the above calculations shall be
rounded, if necessary, to the nearest one hundred-thousandth of a percentage
point, with five one-millionths of a percentage point rounded upwards (e.g.,
9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar
amounts used in or resulting from such calculations shall be rounded to the
nearest cent (with one-half cent being rounded upwards).

                                      -24-
<PAGE>

          The Floating Interest Rate shall in no event be higher than the
maximum rate permitted by the law of the State of New York, or, if higher, the
law of the United States of America.

          Upon the request of the Holder of this Security, the Calculation Agent
shall provide the interest rate then in effect with respect to this Security.
All calculations of the Calculation Agent, in the absence of manifest error,
shall be conclusive for all purposes and binding on the Company, the Guarantor
and the Holder of this Security. So long as the Floating Interest Rate is
required to be determined with respect to this Security, there shall at all
times be a Calculation Agent. In the event that any then acting Calculation
Agent shall be unable or unwilling to act, or that such Calculation Agent shall
fail duly to establish the Floating Interest Rate for any Interest Reset Period,
or that the Company proposes to remove such Calculation Agent, the Company shall
appoint, with the written consent of the Trustee, which consent shall not be
unreasonably withheld, another Person which is a bank, trust company, investment
banking firm or other financial institution to act as the Calculation Agent.

          [If Original Securities, then insert: Pursuant to the Exchange and
Registration Rights Agreement (the "Registration Rights Agreement"), dated as of
May 24, 2001, by and among the Company, the Guarantor and the Purchasers (as
defined therein), the Company and the Guarantor have agreed for the benefit of
the Holders from time to time of the Securities that they will (i) file under
the Securities Act, no later than July 23, 2001, a registration statement (the
"Exchange Registration Statement") registering securities substantially
identical to the Securities (except that such securities will not contain terms
with respect to the Special Interest payments described below or transfer
restrictions) pursuant to an exchange offer (the "Exchange Offer"), (ii) use
their best efforts to cause the Exchange Registration Statement to become
effective under the Securities Act no later than November 20, 2001, and (iii)
use their best efforts to cause the Exchange Offer to remain open at least 30
business days and to commence and complete the Exchange Offer no later than 45
days after the Exchange Registration Statement has become effective; PROVIDED,
HOWEVER, that if (a) on or prior to the time the Exchange Offer is completed
existing Commission interpretations are changed such that this Security or the
Guarantee endorsed hereon is not or would not be, upon receipt under the
Exchange Offer, transferable by the Holder of this Security without restriction
under the Securities Act, (b) the Exchange Offer has not been completed by
January 4, 2002 or

                                      -25-
<PAGE>

(c) the Exchange Offer is not available to the Holder of this Security, the
Company and the Guarantor have agreed, in lieu of (or, in the case of clause
(c), in addition to) conducting the Exchange Offer, to file under the Securities
Act no later than the later of 30 days after the time such obligation to file
arises, a "shelf" registration statement providing for the registration of and
the sale on a continuous or delayed basis by the Holder of this Security (such
registration statement, the "Shelf Registration Statement") and to use their
respective best efforts to cause the Shelf Registration Statement to become
effective no later than 120 days after it is filed.

          In the event that (i) the Company and the Guarantor have not filed the
Exchange Registration Statement or, if applicable, Shelf Registration Statement
on or before the date on which such registration statement is required to be
filed in the respective time frames provided above, or (ii) such Exchange
Registration Statement or, if applicable, Shelf Registration Statement has not
become effective on or before the date on which such registration statement is
required to become effective in the respective time frames provided above, or
(iii) the Exchange Offer has not been completed within 45 days after the initial
effective date of the Exchange Registration Statement (if the Exchange Offer is
then required to be made) or (iv) the Exchange Registration Statement or, if
applicable, Shelf Registration Statement is filed and declared effective but
shall thereafter either be withdrawn by the Company and the Guarantor or shall
become subject to an effective stop order issued pursuant to Section 8(d) of the
Securities Act suspending the effectiveness of such registration statement
(except as specifically permitted in the Indenture) without being succeeded
immediately by an additional registration statement filed and declared
effective, in each case (i) through (iv) upon the terms and conditions set forth
in the Registration Rights Agreement (each such event referred to in clauses (i)
through (iv), a "Registration Default" and each period during which a
Registration Default has occurred and is continuing, a "Registration Default
Period"), then interest will accrue (in addition to any stated interest on this
Security) at a per annum rate of 0.25% for the first 90 days of the Registration
Default Period (the "Step-Up"), at a per annum rate of 0.50% for the second 90
days of the Registration Default Period, at a per annum rate of 0.75% for the
third 90 days of the Registration Default Period and at a per annum rate of 1.0%
thereafter for the remaining portion of the Registration Default Period (each
such increase, a "Subsequent Step-Up"). Interest accruing as a result of the
Step-Up or any Subsequent Step-Up (which shall be computed on the basis of a
365-day year) is referred to

                                      -26-
<PAGE>

herein as "Special Interest," and will be payable at such increased rate until
such time as the Registration Default Period is no longer continuing, after
which such interest rate will be restored to its initial rate (such event, a
"Step-Down Date"). Accrued Special Interest, if any, shall be paid semi-annually
on May 15 and November 15 in each year; and the amount of accrued Special
Interest shall be determined on the basis of the number of days actually
elapsed. Any accrued and unpaid interest (including Special Interest) on this
Security upon the issuance of an Exchange Security (as defined in the Indenture)
in exchange for this Security shall cease to be payable to the Holder hereof but
such accrued and unpaid interest (including Special Interest) shall be payable
on the next Interest Payment Date for such Exchange Security to the Holder
thereof on the related Regular Record Date.]

          The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be the May 1 or November 1 (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date. Any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to the Holder of this Security not less than 10 days prior to such Special
Record Date, or be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Securities may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided in said Indenture.

          Payment of the principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in San Francisco, California, Salt Lake City, Utah and the Borough of
Manhattan, The City of New York and at any other office or agency maintained by
the Company for such purpose, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts; PROVIDED, HOWEVER, that at the option of the Company payment of
interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register.

set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

the Trustee referred to on the reverse hereof by manual signature, neither this

SECTION 203. FORM OF REVERSE OF SECURITY.

          This Security is one of a duly authorized issue of Securities of the
Company designated as its Fixed/Floating Rate Guaranteed Notes due May 15, 2011
(herein called the "Securities"), limited in aggregate principal amount to
$200,000,000, issued and to be issued under an Indenture, dated as of May 24,
2001 (herein called the "Indenture"), among the Company, the Guarantor and Chase
Manhattan Bank and Trust Company, National Association, as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Guarantor, the Trustee, the
holders of Senior Indebtedness

                                      -28-
<PAGE>

and the Holder of this Security and of the terms upon which this Security is,
and is to be, authenticated and delivered.

          This Security is subject to redemption upon not less than 30 days'
notice by mail, at any time on or after May 15, 2006 on any Interest Payment
Date, as a whole or in part, at the election of the Company, at a Redemption
Price equal to 100% of the principal amount, together in the case of any such
redemption with accrued but unpaid interest to the Redemption Date, but interest
installments whose Stated Maturity is on or prior to such Redemption Date will
be payable to the Holder of this Security, or one or more Predecessor
Securities, of record at the close of business on the relevant Record Dates
referred to on the face hereof, all as provided in the Indenture.

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

          If an Event of Default shall occur and be continuing, the principal of
this Security may be declared due and payable in the manner and with the effect
provided in the Indenture. The principal of this Security may not be declared
due and payable upon a Default, defined in the Indenture as (i) an Event of
Default; (ii) failure to pay interest due on this Security, continued for a
period of 30 days; (iii) failure to pay principal of this Security at Maturity;
and (iv) failure to perform any other covenant or warranty of the Company or the
Guarantor in the Indenture, continued for a period of 60 days after written
notice as provided in the Indenture, unless such a Default is an Event of
Default, although the Trustee may protect the rights of the Holder of this
Security by appropriate judicial proceeding as provided in the Indenture.

          This Security does not have the benefit of any sinking fund
obligations.

          This Global Security shall be exchangeable for Securities registered
in the names of Persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Company and the Guarantor that it is unwilling or unable
to continue as the Depositary or if at any time such Depositary ceases to be a
clearing agency registered under the Securities Exchange Act of 1934, at a time
when such Depositary is required to be so registered in order to act as
Depositary, and the Company or the Guarantor fails to appoint a successor
Depositary under the Indenture, (ii) the Company or the Guarantor executes and
delivers to the

                                      -29-
<PAGE>

Trustee a Company Order or Guarantor Order, as the case may be, that the Global
Security shall be so exchangeable or (iii) there shall have occurred and be
continuing an Event of Default with respect to the Securities. To the extent
that the Global Security is exchangeable pursuant to the preceding sentence, it
shall be exchangeable for Securities registered in such names as the Depositary
may direct. In the event of a deposit or withdrawal of an interest in this
Security (including upon an exchange, transfer, redemption or repurchase of this
Security in part only) effected in accordance with the Applicable Procedures,
the Security Registrar, upon receipt of notice of such event from the
Depository's custodian for this Security, shall make an adjustment on its
records to reflect an increase or decrease of the Outstanding principal amount
of this Security resulting from such deposit or withdrawal, as the case may be.

          Unless the context otherwise requires, the Original Securities (as
defined in the Indenture) and the Exchange Securities (as defined in the
Indenture) shall constitute one series for all purposes under the Indenture,
including without limitation, amendments, waivers and redemptions.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the Guarantor and the rights of the Holders of the Securities under
the Indenture at any time by the Company, the Guarantor and the Trustee with the
consent of the Holders of 66 2/3% in aggregate principal amount of the
Securities at the time Outstanding. The Indenture also contains provisions
permitting the Holders of specified percentages in aggregate principal amount of
the Securities at the time Outstanding, on behalf of the Holders of all the
Securities, to waive compliance by the Company or the Guarantor with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if

                                      -30-
<PAGE>

any) and interest on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

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

          The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of a different
authorized denomination, as requested by the Holder surrendering the same.

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

          Prior to due presentment of this Security for registration of
transfer, the Company, the Guarantor, the Trustee and any agent of the Company,
the Guarantor or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this Security be
overdue, and neither the Company, the Guarantor, the Trustee nor any such agent
shall be affected by notice to the contrary.

          This Security shall be governed by and construed in accordance with
the laws of the State of New York, but without regard to principles of conflict
of laws.

          All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

SECTION 205. FORM OF GUARANTEE.

          The form of Guarantee to be endorsed on all Securities shall be
substantially as follows:

                                    GUARANTEE

                                       OF

                              ZIONS BANCORPORATION

          For value received, Zions Bancorporation, a corporation duly organized
and existing under the laws of the State of Utah (herein called the
"Guarantor"), hereby unconditionally guarantees to the Holder of the Security
upon which this Guarantee is endorsed the due and punctual payment of the
principal of (and premium, if any) and interest on said Security when and as the
same shall become due and payable, whether at maturity, by acceleration or
redemption or otherwise, according to the terms thereof and of the Indenture
referred to therein. In case of the failure of Zions Financial Corp. or any
successor thereto (the "Company") punctually to pay any such principal, premium
or interest, the Guarantor hereby agrees to cause any such payment to be made
punctually when and as the same shall become due and payable, whether at
maturity, upon acceleration or otherwise, and as if such payment were made by
the Company.

                                      -32-
<PAGE>

          The Guarantor hereby agrees that its obligations hereunder shall be as
principal and not merely as surety, and shall be absolute and unconditional,
irrespective of, and shall be unaffected by, any invalidity, irregularity or
unenforceability of said Security or said Indenture, any failure to enforce the
provisions of said Security or said Indenture, or any waiver, modification,
consent or indulgence granted to the Company with respect thereto, by the Holder
of said Security or the Trustee under said Indenture, the recovery of any
judgment against the Company or any action to enforce the same, or any other
circumstances which may otherwise constitute a legal or equitable discharge of a
surety or guarantor. The Guarantor hereby waives diligence, presentment, demand
of payment, filing of claims with a court in the event of merger, insolvency or
bankruptcy of the Company, any right to require a proceeding first against the
Company, protest or notice with respect to said Security or the indebtedness
evidenced thereby and all demands whatsoever, and covenants that this Guarantee
will not be discharged except by payment in full of the principal of and
premium, if any, and interest on said Security and the complete performance of
all other obligations contained in said Security.

          The Guarantor shall be subrogated to all rights of the Holder of said
Security against the Company in respect of any amounts paid to such Holder by
the Guarantor pursuant to the provisions of this Guarantee; PROVIDED, HOWEVER,
that the Guarantor shall not be entitled to enforce, or to receive any payments
arising out of or based upon, such right of subrogation until the principal of
(and premium, if any) and interest on all Securities issued under said Indenture
shall have been paid in full.

          Subject to the next following paragraph, the Guarantor hereby
certifies and warrants that all acts, conditions and things required to be done
and performed and to have happened precedent to the creation and issuance of
this Guarantee and to constitute the same the valid obligation of the Guarantor
have been done and performed and have happened in due compliance with all
applicable laws.

          Claims under this Guarantee are, to the extent provided in this
Indenture, subordinate and subject in right of payment to the prior payment in
full of all Senior Indebtedness, and as provided in the Indenture to payments to
creditors in respect of General Obligations, and this Guarantee is issued
subject to the provisions of this Indenture with respect thereto. Each Holder of
a Security upon which this Guarantee is endorsed, by accepting the same, (a)
agrees to and shall be bound by such provisions,

                                      -33-
<PAGE>

(b) authorizes and directs the Trustee on his behalf to take such action as may
be necessary or appropriate to effectuate the subordination so provided and (c)
appoints the Trustee his attorney-in-fact for any and all such purposes.

          This Guarantee shall not be valid or become obligatory for any purpose
until the certificate of authentication on said Security shall have been signed
manually by or on behalf of the Trustee under said Indenture.

          The Guarantee shall be deemed to be a contract made under the laws of
the State of New York, and for all purposes shall be governed by and construed
in accordance with the laws of the State of New York, except as otherwise
required by mandatory provisions of law.

          IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be duly
executed by its duly authorized officer under its corporate seal.

                                 The Securities

SECTION 301. TITLE AND TERMS.

          The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to $200,000,000,
except for Securities authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Securities pursuant to Section 304,
305, 306 or 1006.

                                      -34-
<PAGE>

          The Securities shall be known and designated as the "Fixed/Floating
Rate Guaranteed Notes Due May 15, 2011" of the Company. Their Stated Maturity
shall be May 15, 2011, and they shall bear interest at the rate provided for in
the Form of Face of Security in Section 202, from May 24, 2001 or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, as the case may be, payable semi-annually on May 15 and November 15,
commencing November 15, 2001 until the principal thereof is paid or made
available for payment; PROVIDED, HOWEVER, with respect to Original Securities,
if there has been a Registration Default, a Step-Up will occur and the Original
Securities will from then bear Special Interest until the Registration Default
Period is no longer continuing and, if the Registration Default Period continues
for the applicable period, Subsequent Step-Ups will occur and the Original
Securities will from then bear Special Interest until the Registration Default
Period is no longer continuing. Accrued Special Interest, if any, shall be paid
in cash in arrears semi-annually on May 15 and November 15 in each year, and the
amount of accrued Special Interest shall be determined on the basis of the
number of days actually elapsed. In connection with the cash payment of any
Special Interest, the Company or the Guarantor shall notify the Trustee (the
"Special Interest Notice") on or before the later to occur of (i) the Regular
Record Date preceding such payment of any Special Interest, and (ii) the date on
which any such Special Interest begins to accrue, of the amount of Special
Interest to be paid by the Company on the next Interest Payment Date. In the
event of the occurrence of a Step-Down Date during the period between the date
on which the Special Interest Notice is given and the next Interest Payment
Date, the Company shall so notify the Trustee and shall provide the Trustee with
the revised amount of Special Interest to be paid by the Company on such
Interest Payment Date.

          If the Security is issued in the form of a Global Security, payments
of the principal of (and premium, if any) and interest on this Security shall be
made in immediately available funds to the Depositary. If the Securities are
issued in certificated form, the principal of (and premium, if any) and interest
on the Securities shall be payable at the office or agency of the Company in San
Francisco, California, Salt Lake City, Utah and the Borough of Manhattan, The
City of New York maintained for such purpose and at any other office or agency
maintained by the Company for such purpose; PROVIDED, HOWEVER, that at the
option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register.

                                      -35-
<PAGE>

          The Securities shall be redeemable as provided in Article Twelve.

          The Securities shall not have the benefit of any sinking fund
obligations.

          The Guarantees shall be subordinated in right of payment to Senior
Indebtedness as provided in Article Thirteen and the Original Securities and the
Exchange Securities shall rank pari passu.

          Unless the context otherwise requires, the Original Securities and the
Exchange Securities shall constitute one series for all purposes under the
Indenture, including without limitation, amendments, waivers and redemptions.

SECTION 302. DENOMINATIONS.

          The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 and any integral multiple thereof.

SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

          The Securities shall be executed on behalf of the Company and the
Guarantees endorsed thereon shall be executed on behalf of the Guarantor by
respectively its Chairman of the Board, its Vice Chairman of the Board, its
President or one of its Vice Presidents, under its corporate seal reproduced
thereon attested by its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities or Guarantees may be manual
or facsimile.

          Securities and Guarantees bearing the manual or facsimile signatures
of individuals who were at any time the proper officers of the Company or the
Guarantor, respectively, shall bind the Company and, the Guarantor,
respectively, notwithstanding that such individuals or any of them have ceased
to hold such offices prior to the authentication and delivery of such Securities
and Guarantees or did not hold such offices at the date of such Securities and
Guarantees.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company, and
with Guarantees endorsed thereon executed by the Guarantor, to the Trustee for
authentication, together with a Company

                                      -36-
<PAGE>

Order for the authentication and delivery of such Securities; and the Trustee in
accordance with such Company Order shall authenticate and deliver such
Securities as in this Indenture provided and not otherwise.

          Each Security shall be dated the date of its authentication. Each
Guarantee shall be dated the date of the initial issuance of the Securities.

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

SECTION 304. TEMPORARY SECURITIES.

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

          If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 1102, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of
authorized denominations. Until so exchanged the temporary Securities and the
Guarantees endorsed thereon shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities and the Guarantees
endorsed thereon.

                                      -37-
<PAGE>

SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 1102 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided. Such Security Register shall
distinguish between Original Securities and Exchange Securities.

          Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 1102 for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities (having Guarantees duly endorsed thereon) of any authorized
denominations and of a like aggregate principal amount (having Guarantees duly
endorsed thereon).

          At the option of the Holder, and subject to the other provisions of
this Section 305, Securities may be exchanged for other Securities and bearing
such restrictive legends as may be required by this Indenture of any authorized
denominations and of a like aggregate principal amount, upon surrender of the
Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive and the Guarantor shall execute the Guarantees endorsed
thereon.

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

          Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form

                                      -38-
<PAGE>

satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304 or 906 not involving any transfer.

          The Company shall not be required (i) to issue, register the transfer
of or exchange any Security during a period beginning at the opening of business
15 days before the day of the mailing of a notice of redemption of Securities
selected for redemption under Section 1104 and ending at the close of business
on the day of such mailing, or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

          Notwithstanding any other provision of this Indenture, a beneficial
interest in a Global Security may not be transferred to, or registered or
exchanged for a Security registered in the name of any Person other than the
Depositary for such Global Security or any nominee thereof, and no such transfer
may be registered, unless (i) the Depositary (x) notifies the Company and the
Guarantor it is unwilling or unable to continue as Depositary for the Global
Security or (y) has ceased to be a clearing agency registered under the Exchange
Act and in either case the Company or the Guarantor thereupon fails to appoint a
successor Depositary, (ii) the Company or the Guarantor, at its option, executes
and delivers a Company Order or Guarantor Order, as the case may be, that the
Global Security shall be exchangeable, or (iii) there shall have occurred and be
continuing an Event of Default with respect to the Securities evidenced by the
Global Security. Notwithstanding any other provision of this Indenture, a Global
Security to which the restriction set forth in the preceding sentence shall have
ceased to apply may be transferred only to, and may be registered only in the
name or names of, such Person or Persons as the Depositary for such Global
Security shall have directed and no transfer thereof other than such a transfer
may be registered.

          Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security to which the
restriction set forth in the first sentence of the preceding paragraph shall
apply,

                                      -39-
<PAGE>

whether pursuant to Section 304, 305, 306 or 1006 or otherwise, shall be
authenticated and delivered in the form of, and shall be, a Global Security.

          If at any time the Depositary for a Global Security notifies the
Company and the Guarantor that it is unwilling or unable to continue as
Depositary for such Global Security or if at any time the Depositary for a
Global Security has ceased to be a clearing agency registered as such under the
Exchange Act, at a time when the Depositary for a Global Security is required to
be so registered in order to act as a Depositary, the Company shall appoint a
successor Depositary with respect to such Global Security. If a successor
Depositary is not appointed by the Company within 90 days after the Company and
the Guarantor receive such notice or become aware of such condition, the Company
shall execute, and the Trustee, upon receipt of a Company Order for
authentication and delivery of definitive Securities, shall authenticate and
deliver Securities in a definitive registered form in an aggregate principal
amount of the Global Security in exchange for such Global Security.

          The Company may at any time and in its sole discretion determine that
the Securities issued in the form of one or more Global Securities shall no
longer be represented by a Global Security. In such event the Company shall
execute, and the Trustee, upon receipt of a Company Order for authentication and
delivery of definitive Securities, shall authenticate and deliver Securities in
a definitive registered form without coupons, in any authorized denominations,
in an aggregate principal amount equal to the principal amount of the Global
Security, in exchange for such Global Security.

          Upon the exchange of a Global Security for Securities in a definitive
registered form in authorized denominations, such Global Security shall be
canceled by the Trustee. Securities in a definitive registered form issued in
exchange for a Global Security pursuant to this Section 305 shall be registered
in such names and in such authorized denominations as the Depositary for such
Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall deliver
such Securities to or as directed by the Persons in whose names such Securities
are so registered.

          No holder of any beneficial interest in any Global Security held on
its behalf by a Depositary shall have any rights under this Indenture with
respect to such Global

                                      -40-
<PAGE>

Security, and such Depositary may be treated by the Company, the Guarantor, the
Trustee, and any agent of the Company, the Guarantor or the Trustee as the owner
of such Global Security for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall impair, as between a Depositary and such holders
of beneficial interests, the operation of customary practices governing the
exercise of the rights of the Depositary as Holder of any Security.

          Original Securities and their Successor Securities shall bear a
Restricted Securities Legend. Registered Securities shall not bear a Restricted
Securities Legend.

SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

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

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

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

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

          Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall

                                      -41-
<PAGE>

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

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

SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

          Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

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

                    (1) The Company or the Guarantor may elect to make payment
          of any Defaulted Interest to the Persons in whose names the Securities
          (or their respective Predecessor Securities) are registered at the
          close of business on a Special Record Date for the payment of such
          Defaulted Interest, which shall be fixed in the following manner. The
          Company or the Guarantor shall notify the Trustee in writing of the
          amount of Defaulted Interest proposed to be paid on each Security and
          the date of the proposed payment, and at the same time the Company or
          the Guarantor, as the case may be, shall deposit with the Trustee an
          amount of money equal to the aggregate amount proposed to be paid in
          respect of such Defaulted Interest or shall make arrangements
          satisfactory to the Trustee for such deposit prior to the date of the

                                      -42-
<PAGE>

          proposed payment, such money when deposited to be held in trust for
          the benefit of the Persons entitled to such Defaulted Interest as in
          this Clause provided. Thereupon the Trustee shall fix a Special Record
          Date for the payment of such Defaulted Interest which shall be not
          more than 15 days and not less than 10 days prior to the date of the
          proposed payment and not less than 10 days after the receipt by the
          Trustee of the notice of the proposed payment. The Trustee shall
          promptly notify the Company or the Guarantor, as the case may be, of
          such Special Record Date and, in the name and at the expense of the
          Company, shall cause notice of the proposed payment of such Defaulted
          Interest and the Special Record Date therefor to be mailed,
          first-class postage prepaid, to each Holder at his address as it
          appears in the Security Register, not less than 10 days prior to such
          Special Record Date. Notice of the proposed payment of such Defaulted
          Interest and the Special Record Date therefor having been so mailed,
          such Defaulted Interest shall be paid to the Persons in whose names
          the Securities (or their respective Predecessor Securities) are
          registered at the close of business on such Special Record Date and
          shall no longer be payable pursuant to the following Clause (2).

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

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

                                      -43-

SECTION 308. PERSONS DEEMED OWNERS.

          Prior to due presentment of a Security for registration of transfer,
the Company, the Guarantor, the Trustee and any agent of the Company, the
Guarantor or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 307) interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and neither the Company, the Guarantor, the Trustee nor any agent of
the Company, the Guarantor or the Trustee shall be affected by notice to the
contrary.

          None of the Company, the Guarantor, the Trustee or any agent of the
Company or the Trustee shall have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership
interests of a Security in global form, or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.
Notwithstanding the foregoing, with respect to any Security in global form,
nothing herein shall prevent the Company or Trustee, or any agent of the Company
or the Trustee, from giving effect to any written certification, proxy or other
authorization furnished by an Depositary (or its nominee), as a Holder, with

                            GUARANTEE OF SECURITIES

SECTION 401. UNCONDITIONAL GUARANTEE.

          The Guarantor hereby unconditionally guarantees to each Holder of a
Security authenticated and delivered by the Trustee the due and punctual payment
of the principal of (and premium, if any) and interest on such Security when and
as the same shall become due and payable, whether at maturity, by acceleration
or otherwise, according to the terms of such Security and of this Indenture. In
case of the failure of the Company punctually to pay any such principal, premium
or interest, the Guarantor hereby agrees to cause any such payment to be made
punctually when and as the same shall become due and payable, whether at
maturity, upon acceleration or otherwise, and as if such payment were made by
the Company.

          The Guarantor hereby agrees that its obligations hereunder shall be as
principal and not merely as surety, and shall be absolute and unconditional,
irrespective of, and shall be unaffected by, any invalidity, irregularity or
unenforceability of such Security or said Indenture, any failure to enforce the
provisions of such Security or this Indenture, or any waiver, modification,
consent or indulgence granted to the Company with respect thereto, by the Holder
of such Security or the Trustee under said

                                      -45-
<PAGE>

Indenture, the recovery of any judgment against the Company or any action to
enforce the same, or any other circumstances which may otherwise constitute a
legal or equitable discharge of a surety or guarantor. The Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court
in the event of merger, insolvency or bankruptcy of the Company, any right to
require a proceeding first against the Company, protest or notice with respect
to any such Security or the indebtedness evidenced thereby and all demands
whatsoever, and covenants that this Guarantee will not be discharged except by
payment in full of the principal of and of and premium, if any, and interest on
the Securities and the complete performance of all other obligations contained
in such Security.

          The Guarantor shall be subrogated to all rights of the Holder of any
Security against the Company in respect of any amounts paid to such Holder by
the Guarantor pursuant to the provisions of this Guarantee; provided, however,
that the Guarantor shall not be entitled to enforce, or to receive any payments
arising out of or based upon, such right of subrogation until the principal of
(and premium, if any) and interest on all Securities shall have been paid in
full.

          Claims under the Guarantee are, to the extent provided in this
Indenture, subordinate and subject in right of payment to the prior payment in
full of all Senior Indebtedness, and as provided in the Indenture to payments to
creditors in respect of General Obligations, and the Guarantee is issued subject
to the provisions of this Indenture with respect thereto. Each Holder of a
Security upon which the Guarantee is endorsed, by accepting the same, (a) agrees
to and shall be bound by such provisions, (b) authorizes and directs the Trustee
on his behalf to take such action as may be necessary or appropriate to
effectuate the subordination so provided and (c) appoints the Trustee his
attorney-in-fact for any and all such purposes.

SECTION 402. EXECUTION OF GUARANTEES.

          To evidence its Guarantee to the Holders specified in Section 401, the
Guarantor hereby agrees to execute the Guarantee in substantially the form above
recited to be endorsed on each Security authenticated and delivered by the
Trustee. Each such Guarantee shall be executed on behalf of the Guarantor and
dated as set forth in Section 303 prior to the authentication of the Security on
which it is endorsed, and the delivery of such Security by the Trustee, after
the authentication thereof hereunder, shall constitute due delivery of such
Guarantee on behalf of the Guarantor.

          The Guarantee set forth in this Article shall not be valid or become
obligatory for any purpose with respect to a Security until the certificate of
authentication on such Security shall have been signed by the Trustee.

determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the

     principal of Securities which have become due solely by such declaration
     of acceleration, have been cured or waived as provided in Section 613.

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

SECTION 603. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

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

          (2) default is made in the payment of the principal of (or premium,
     if any, on) any Security at the Maturity thereof, the Company will, upon
     demand of the Trustee to the Company and the Guarantor, pay to it, for
     the benefit of the Holders of such Securities, the whole amount then due
     and payable on such Securities for principal (and premium, if any) and
     interest, and, to the extent that payment of such interest shall be
     legally enforceable, interest on any overdue principal (and premium, if
     any) and on any overdue interest, at the rate borne by the Securities,
     and, in addition thereto, such further amount as shall be sufficient to
     cover the costs and expenses of collection, including the reasonable
     compensation, expenses, disbursements and advances of the Trustee, its
     agents and counsel, and, upon such demand of the Trustee, if the Company
     shall fail to pay such amounts forthwith upon such demand, the Guarantor
     shall pay to it, for the benefit of the Holders of such Securities, the
     whole amount then due and payable under the Guarantees, and, to the
     extent that payment of such interest shall be legally enforceable,
     interest on any overdue principal (and premium, if any) and on any
     overdue interest, at the rate borne by the Securities and due in respect
     of the Guarantees, and, in addition thereto, such further amount as
     shall be sufficient to cover the costs and expenses of collection,
     including the reasonable compensation, expenses, disbursements and
     advances of the Trustee, its agents and counsel.

          If the Company or the Guarantor fails to pay such amounts forthwith
upon such demand, the Trustee, in its own name and as trustee of an express
trust, may institute a judicial proceeding for the collection of the sums so due
and unpaid, may prosecute such proceeding to judgment or final decree and may
enforce

                                      -53-

the same against the Company or the Guarantor or any other obligor upon such
Security and collect the monies adjudged or decreed to be payable in the manner
provided by law out of the property of the Company or the Guarantor or any other
obligor upon such Security, wherever situated.

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

SECTION 604. TRUSTEE MAY FILE PROOFS OF CLAIM.

Guarantor (or any other obligor upon the Securities), their respective property
or their respective creditors, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the Holders
and the Trustee allowed in any such proceeding. In particular, the Trustee shall
be authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 707.

          No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a

trustee in bankruptcy or similar official and be a member of the creditors' or
other similar committee.

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

SECTION 606. APPLICATION OF MONEY COLLECTED.

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

          FIRST: To the payment of all amounts due the Trustee under Section
707; and

          SECOND: To the payment of the amounts then due and unpaid for
principal of (and premium, if any) and interest on the Securities in respect of

payable on such Securities for principal (and premium, if any) and interest,
respectively.

SECTION 607. LIMITATION ON SUITS.

proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a

                                      -55-
<PAGE>

receiver or trustee, or for any other remedy hereunder, unless

          (1) such Holder has previously given written notice to the Trustee
     of a continuing Default;

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

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

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

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

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

             INTEREST.

any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date) and to institute suit for the enforcement of any such payment, and such

                                      -56-

rights shall not be impaired without the consent of such Holder.

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Guarantor, the Trustee and

positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders shall continue as though no such proceeding had been instituted.

SECTION 610. RIGHTS AND REMEDIES CUMULATIVE.

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 611. DELAY OR OMISSION NOT WAIVER.

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

SECTION 612. CONTROL BY HOLDERS.

          The Holders of a majority in principal amount of the Outstanding

                                      -57-
<PAGE>

          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture or expose the Trustee to personal liability, and

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

SECTION 613. WAIVER OF PAST DEFAULTS.

          The Holders of not less than a majority in principal amount of the

any past default hereunder and its consequences, except a default

          (1) in the payment of the principal of (or premium, if any) or
     interest on any Security, or

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

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

SECTION 614.UNDERTAKING FOR COSTS.

          In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; PROVIDED, that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company or the Guarantor.

SECTION 615. WAIVER OF STAY OR EXTENSION LAWS.

          The Company and the Guarantor covenant (to the extent that they may
lawfully do so) that they will not at any time insist upon, or plead, or in any
manner whatsoever

                                      -58-

<PAGE>

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

SECTION 701. CERTAIN DUTIES AND RESPONSIBILITIES.

          Except as otherwise provided, the duties and responsibilities of the
Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the
foregoing, no provision of this Indenture shall require the Trustee to expend or

of any of its duties hereunder, or in the exercise of any of its rights or
powers.

          The Trustee shall, prior to the occurrence of a Default or Event of
Default of which the Trustee is deemed to have knowledge, and after the curing
of all Defaults or Events of Default which may have occurred, perform such
duties and only such duties as are specifically set forth in this Indenture, and
no implied covenants or obligations shall be read into this Indenture or any
other related document against the Trustee. The right of the Trustee to perform
any discretionary act enumerated or contemplated in this Indenture or other
related documents shall not be construed as a duty.

          The Trustee shall, during the existence of any Default or Event of
Default which it is deemed to have knowledge of and which has not been cured,
exercise such of the rights and powers vested in it by this Indenture, and use
the same degree of care and skill in their exercise, as a prudent person would
exercise or use under the circumstances in the conduct of the prudent person's
own affairs.

          The Trustee shall not be liable for any error of judgment made in good
faith by any Responsible Officer of

                                      -59-

the Trustee unless the Trustee was negligent in ascertaining the pertinent
facts. The Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of the
Holders of a majority in aggregate principal amount of the Securities
Outstanding relating to the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or the exercise of any trust or power
conferred upon the Trustee, under this Indenture. Notwithstanding the foregoing,
no provision of this Indenture shall be construed to relieve the Trustee from
liability for its own negligent action, its own negligent failure to act, or its
own wilful misconduct.

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

SECTION 702. NOTICE OF DEFAULTS.

such notice to Holders shall be given until at least 30 days after the
occurrence thereof. For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, a
Default.

          The Trustee shall not be charged with knowledge of any Default or
Event of Default under this Indenture or related documents unless (i) a
Responsible Officer of the Trustee shall have actual knowledge of such Default
or Event of Default or (ii) the Trustee shall have received notice in writing of
such Default or Event of Default by the Company, the Guarantor or by the Holders
of at least twenty-five percent (25%) in aggregate principal amount of the

appointed by the Company and the Guarantor. If no successor Trustee shall have
been so appointed by the Company and the Guarantor or the Holders and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for

instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,

rights, powers, trusts and duties of the retiring Trustee; but, on request of
the Company, the Guarantor or the successor Trustee, such retiring Trustee
shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder. Upon

SECTION 1103. MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST.

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

          Whenever the Company shall have one or more Paying Agents, it will,
prior to each due date of the principal of (and premium, if any) or interest on
any Securities, deposit with a Paying Agent a sum sufficient to pay such amount,
such sum to be held as provided by the Trust Indenture Act, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of its
action or failure so to act.

          The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will (i) comply with the provisions of the Trust Indenture Act
applicable to it as a Paying Agent and (ii) during the continuance of any
default by the Company or the Guarantor (or any other obligor upon the
Securities) in the making of any payment in respect of the Securities, upon the
written request of the Trustee, forthwith pay to the Trustee all sums held in
trust by such Paying Agent as such.

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

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due

                                      -77-

<PAGE>

and payable shall be paid to the Company (or if deposited by the Guarantor, paid
to the Guarantor on Guarantor Request), or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company and the Guarantor for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company or the
Guarantor, as the case may be.

SECTION 1104. STATEMENT BY OFFICERS AS TO DEFAULT.

       Each of the Company and the Guarantor will deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company or the
Guarantor, as the case may be, ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company or the Guarantor, as the case may be, is in default in the
performance and observance of any of the terms, provisions and conditions of
this Indenture (without regard to any period of grace or requirement of notice
provided hereunder) and, if the Company or the Guarantor, as the case may be,
shall be in default, specifying all such defaults and the nature and status
thereof of which they may have knowledge.

SECTION 1105. EXISTENCE.

          Subject to Article Nine, the Company and the Guarantor will do or
cause to be done all things necessary to preserve and keep in full force and
effect their respective existence, rights (charter and statutory), as
applicable, and franchises, and the existence, rights (charter and statutory)
and franchises of any Major Constituent Bank; PROVIDED, HOWEVER, that neither
the Company nor the Guarantor shall be required to preserve any such right or
franchise if the Board of Directors of the Company (with respect to the Company
only) or the Guarantor (with respect to the Guarantor or any Major Constituent
Bank), as the case may be, shall determine that the

                                      -78-

<PAGE>

preservation thereof is no longer desirable in the conduct of the business of
the Company or the Guarantor or such Major Constituent Bank, as the case may be,
and that the loss thereof is not disadvantageous in any material respect to the
Holders.

SECTION 1106. PAYMENT OF TAXES AND OTHER CLAIMS.

          The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary of the
Company or upon the income, profits or property of the Company or any Subsidiary
of the Company, and (2) all lawful claims for labor, materials and supplies
which, if unpaid, might by law become a lien upon the property of the Company or
any Subsidiary of the Company; PROVIDED, HOWEVER, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

          The Guarantor will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Guarantor or any Subsidiary of
the Guarantor or upon the income, profits or property of the Guarantor or any
Subsidiary of the Guarantor, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Guarantor or any Subsidiary of the Guarantor; PROVIDED, HOWEVER, that the
Guarantor shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.

SECTION1 107. GUARANTOR STATEMENT AS TO COMPLIANCE.

          The Guarantor will deliver to the Trustee, within 120 days after the
end of each fiscal year, a written statement, which need not comply with Section
102, signed by the Chairman of the Board, a Vice Chairman, the President or a
Vice President and by the Treasurer or an Assistant Treasurer of the Guarantor,
stating, as to each signer thereof, that:

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

                                      -79-

<PAGE>

          (2) to the best of his knowledge, based on such review, (a) the
     Guarantor has fulfilled all its obligations under this Indenture
     throughout such year, or, if there has been a default in the fulfillment
     of any such obligation, specifying each such default known to him and
     the nature and status thereof, and (b) no event has occurred and is
     continuing which is, or after notice or lapse of time or both would
     become, an Event of Default under Section 601, or a Default under
     Section 601 or, if such event has occurred and is continuing, specifying
     such event known to him and the nature and status thereof.

SECTION 1108. WAIVER OF CERTAIN COVENANTS.

          The Company or the Guarantor, as the case may be, may omit in any
particular instance to comply with any covenant or condition set forth in
Sections 1105 to 1107, inclusive, if before the time for such compliance the
Holders of at least 66 2/3% in principal amount of the Outstanding Securities
shall, by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such covenant or condition, but no such waiver
shall extend to or affect such covenant or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Company and the Guarantor and the duties of the Trustee in respect of any
such covenant or condition shall remain in full force and effect.

Trustee of such Redemption Date and of the principal amount of Securities to be
redeemed.

SECTION 1204. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

          If less than all the Securities are to be redeemed, the particular

called for redemption, by such method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to $1,000 or any integral multiple thereof) of the principal amount of
Securities of a denomination larger than $1,000.

          The Trustee shall promptly notify the Company and each Security
Registrar in writing of the Securities selected for redemption and, in the case
of any Securities selected for partial redemption, the principal amount thereof
to be redeemed.

          For all purposes of this Indenture, unless the context otherwise

     Securities, the principal amounts) of the particular Securities to be
     redeemed,

          (4) that on the Redemption Date the Redemption Price will become
     due and payable upon each such Security to be redeemed and that interest
     thereon will cease to accrue on and after said date, and

     for payment of the Redemption Price.

          Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 1206. DEPOSIT OF REDEMPTION PRICE.

          Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1103) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

SECTION 1207. SECURITIES PAYABLE ON REDEMPTION DATE.

          Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; PROVIDED, HOWEVER, that instalments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of

                                      -82-

provisions of Section 307.

          If any Security called for redemption shall not be so paid upon

          Any Security which is to be redeemed only in part shall be surrendered
at an office or agency of the Company designated for that purpose pursuant to
Section 1102 (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly authorized
in writing), and the Company shall execute, and the Trustee shall authenticate
and deliver to the Holder of such Security without service charge, a new
Security or Securities, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

                                ARTICLE THIRTEEN

                          Subordination of Guarantees

SECTION 1301. GUARANTEES SUBORDINATE TO SENIOR INDEBTEDNESS.

          The Guarantor covenants and agrees, and each Holder of a Security, by
his acceptance thereof, likewise covenants and agrees, that, to the extent and
in the manner hereinafter set forth in this Article, the obligations of the
Guarantor under the Guarantees relating to the payment of the principal of (and
premium, if any) and interest on each and all of the Securities are hereby
expressly made subordinate and subject in right of payment to the prior payment
in full of all Senior Indebtedness.

SECTION 1302. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

          In the event of (a) any insolvency or bankruptcy case or proceeding,
or any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Guarantor or to its
creditors, as such, or to its assets, or (b) any

                                      -83-
<PAGE>

liquidation, dissolution or other winding up of the Guarantor, whether voluntary
or involuntary and whether or not involving insolvency or bankruptcy, or (c) any
assignment for the benefit of creditors or any other marshaling of assets and
liabilities of the Guarantor, then and in any such event the holders of Senior
Indebtedness shall be entitled to receive payment in full of all amounts due or
to become due on or in respect of all Senior Indebtedness, or provision shall be
made for such payment, before the Holders of the Securities are entitled to
receive any payment under the Guarantees. Any payment or distribution under the
Guarantees, whether in cash, property or securities, which would otherwise (but
for these provisions) be payable or deliverable in respect of the Guarantees
shall be paid and delivered directly to the holders of Senior Indebtedness in
accordance with the priorities then existing among such holders until all Senior
Indebtedness shall have been paid in full.

          Upon the occurrence of any of the events described in clauses (a), (b)
or (c) of the immediately preceding paragraph, in the event that notwithstanding
the foregoing provisions of this Section the Trustee or the Holder of any
Security shall have received any payment or distribution of assets of the
Guarantor of any kind or character, whether in cash, property or securities,
before all Senior Indebtedness is paid in full or payment thereof provided for,
and if such fact shall, at or prior to the time of such payment or distribution,
have been made known to the Trustee or, as the case may be, such Holder, then
and in such event such payment or distribution shall be paid over or delivered
forthwith to the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee, agent or other Person making payment or distribution of
assets of the Guarantor for application to the payment of all Senior
Indebtedness remaining unpaid, to the extent necessary to pay all Senior
Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

          The consolidation of the Guarantor with, or the merger of the
Guarantor into, another Person or the liquidation or dissolution of the
Guarantor following the conveyance or transfer of its properties and assets
substantially as an entirety to another Person upon the terms and conditions set
forth in Article Nine shall not be deemed a dissolution, winding up,
liquidation, reorganization, assignment for the benefit of creditors or
marshaling of assets and liabilities of the Guarantor for the purposes of this
Section if the Person formed by such consolidation or into which the Guarantor
is merged or which

                                      -84-
<PAGE>

acquires by conveyance or transfer such properties and assets substantially as
an entirety, as the case may be, shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the respective conditions set forth in
Article Nine.

SECTION 1303. PRIOR PAYMENT TO SENIOR INDEBTEDNESS UPON ACCELERATION OF
              SECURITIES.

          In the event that any Securities are declared due and payable before
their Stated Maturity, then and in such event the holders of the Senior
Indebtedness outstanding at the time such Securities so become due and payable
shall be entitled to receive payment in full of all amounts due or to become due
on or in respect of all such Senior Indebtedness, or provision shall be made for
such payment in cash in money or money's worth, before the Holders of the
Securities are entitled to receive any payment by the Guarantor under the
Guarantees.

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

          The provisions of this Section shall not apply to any payment with
respect to which Section 1302 would be applicable.

SECTION 1304. NO PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT.

          (a) In the event and during the continuation of any default in the
payment of principal of (or premium, if any) or interest on any Senior
Indebtedness beyond any applicable grace period with respect thereto, or, or (b)
in the event any judicial proceeding shall be pending with respect to any such
default, then no payment shall be made by the Guarantor under the Guarantees.

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

                                      -85-
<PAGE>

such event such payment shall be paid over and delivered forthwith to the
Guarantor.

          The provisions of this Section shall not apply to any payment with
respect to which Section 1302 would be applicable.

SECTION 1305. PAYMENT PERMITTED IF NO DEFAULT.

          Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Guarantor, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other winding
up, assignment for the benefit of creditors or other marshaling of assets and
liabilities of the Guarantor referred to in Section 1302 or under the conditions
described in Section 1303 or 1304, from making payments at any time under the
Guarantees, or (b) the application by the Trustee of any money deposited with it
hereunder to the payment of or on account of the principal of (and premium, if
any) or interest on the Securities or the retention of such payment by the
Holders, if, at the time of such application by the Trustee, it did not have
knowledge that such payment would have been prohibited by the provisions of this
Article.

SECTION 1306. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.

          Subject to the payment in full of all Senior Indebtedness, the Holders
of the Securities shall be subrogated (equally and ratably with the holders of
all indebtedness of the Guarantor which by its express terms is subordinated to
indebtedness of the Guarantor to substantially the same extent as the
Guarantees, as the case may be, are subordinated and is entitled to like rights
of subrogation) to the rights of the holders of such Senior Indebtedness to
receive payments and distributions of cash, property and securities applicable
to the Senior Indebtedness until all amounts due with respect to the Guarantees
shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Senior Indebtedness of any cash, property or
securities to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article, and no payments over
pursuant to the provisions of this Article to the holders of Senior Indebtedness
by Holders of the Securities or the Trustee, shall, as among the Guarantor, its
creditors other than holders of Senior Indebtedness and the Holders of the
Securities, be deemed to be a payment or

                                      -86-
<PAGE>

distribution by the Guarantor to or on account of the Senior Indebtedness.

SECTION 1307. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

          The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness (and, in the case of Section
1315, the creditors of General Obligations) on the other hand. Nothing contained
in this Article or elsewhere in this Indenture or in the Guarantees is intended
to or shall (a) impair, as among the Guarantor, its creditors other than holders
of Senior Indebtedness and the Holders of the Securities, the obligation of the
Guarantor under the Guarantees, which is absolute and unconditional, and which
is intended to rank equally with all other general obligations of the Guarantor,
to guarantee the payment to the Holders of the Securities as provided in
Guarantees in accordance with their terms; or (b) affect the relative rights
against the Guarantor of the Holders of the Securities and creditors of the
Guarantor other than the holders of Senior Indebtedness; or (c) prevent the
Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, (and under Section 1315 of creditors in respect of General
Obligations) under this Article of the holders of Senior Indebtedness to receive
cash, property and securities otherwise payable or deliverable to the Trustee or
such Holder.

SECTION 1308. TRUSTEE TO EFFECTUATE SUBORDINATION.

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

SECTION 1309. NO WAIVER OF SUBORDINATION PROVISIONS.

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

                                      -87-
<PAGE>

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Indebtedness, or otherwise amend or supplement in any manner Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection
of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights
against the Guarantor and any other Person.

SECTION 1310. NOTICE TO TRUSTEE.

          The Guarantor shall give prompt written notice to the Trustee of any
fact known to the Guarantor which would prohibit the making of any payment to or
by the Trustee in respect of the Guarantees. Notwithstanding the provisions of
this Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Guarantees, unless
and until the Trustee shall have received written notice thereof from the
Guarantor or a holder of Senior Indebtedness or from any trustee therefor; and,
prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 701, shall be entitled in all respects to assume that no
such facts exist; PROVIDED, HOWEVER, that if the Trustee shall not have received
the notice provided for in this Section at least five Business Days prior to the
date upon which by the terms hereof any money may become payable for any
purpose, then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such money and to apply
the same to the purpose for which such money was received and shall not be
affected by any notice to the contrary which may be received by it within five
Business Days prior to such date.

          Subject to the provisions of Section 701, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a

                                      -88-
<PAGE>

holder of Senior Indebtedness or a trustee therefor (or a creditor in respect of
General Obligations) to establish that such notice has been given by a holder of
Senior Indebtedness or a trustee therefor (or a creditor in respect of General
Obligations). In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder
of Senior Indebtedness (or a creditor in respect of General Obligations) to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such Person to furnish evidence to the reasonable satisfaction of
the Trustee as to the amount of Senior Indebtedness (or General Obligations)
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article, and if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

SECTION 1311. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT.

          Upon any payment or distribution of assets of the Guarantor referred
to in this Article, the Trustee, subject to the provisions of Section 701, and
the Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness and other indebtedness of
the Guarantor (and the creditors in respect of General Obligations), the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article.

SECTION 1312. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS (OR
              CREDITORS IN RESPECT OF GENERAL OBLIGATIONS).

          The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness (or creditors in respect of General Obligations)
and shall not be liable to any such holders (or creditors in respect of

                                      -89-
<PAGE>

General Obligations) if it shall in good faith mistakenly pay over or distribute
to Holders of Securities or to the Guarantor, the Guarantor or to any other
Person cash, property or securities to which any holders of Senior Indebtedness
(or creditors in respect of General Obligations) shall be entitled by virtue of
this Article or otherwise.

SECTION 1313. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS; PRESERVATION
              OF TRUSTEE'S RIGHTS.

          The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it (or with respect to any General Obligations owed
to the Trustee as a creditor), to the same extent as any other holder of Senior
Indebtedness (or creditors in respect of General Obligations as the case may
be), and nothing in this Indenture shall deprive the Trustee of any of its
rights as such holder.

          Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 707.

SECTION 1314. ARTICLE APPLICABLE TO PAYING AGENTS.

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company or the Guarantor and be then acting hereunder, the
term "Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article in addition to or in place of the Trustee; PROVIDED,
HOWEVER, that Section 1313 shall not apply to the Company or the Guarantor or
any Affiliate of the Company or the Guarantor if it or such Affiliate acts as
Paying Agent.

SECTION 1315. PAYMENT OF PROCEEDS IN CERTAIN CASES.

          (a) Upon the occurrence of any of the events specified in clauses (a),
(b) and (c) of the first paragraph of Section 1302, the provisions of that
Section shall be given effect to determine the amount of cash, property or
securities which may be payable or deliverable as between the holders of Senior
Indebtedness, on the other hand, and the Holders of Securities, on the other
hand, with respect to the Guarantees.

                                      -90-
<PAGE>

          (b) If, after giving effect to the provisions of Section 1302 and
Section 1306, any amount of cash, property or securities of the Guarantor shall
be available for payment or distribution in respect of the Guarantees ("Excess
Proceeds"), and any creditors in respect of General Obligations shall not have
received payment in full of all amounts due or to become due on or in respect of
such General Obligations, then such Excess Proceeds shall first be applied
(ratably with any amount of cash, property or securities available for payment
or distribution in respect of any other indebtedness of the Guarantor that by
its express terms provides for the payment over of amounts corresponding to
Excess Proceeds to creditors in respect of General Obligations) to pay or
provide for the payment of the General Obligations remaining unpaid, to the
extent necessary to pay all General Obligations in full, after giving effect to
any concurrent payment or distribution to or for creditors in respect of General
Obligations. Any Excess Proceeds remaining after the payment (or provision for
payment) in full of all General Obligations shall be available for payment or
distribution under the Guarantees.

          (c) In the event that, notwithstanding the foregoing provisions of
subsection (b) of this Section, the Trustee or Holder of any Security shall have
received any payment or distribution of assets of the company of any kind or
character, whether in cash, property or securities, before all General
Obligations are paid in full or payment thereof duly provided for, and if such
fact shall, at or prior to the time of such payment or distribution have been
made known to the Trustee or, as the case may be, such Holder, then and in such
event, subject to any obligation that the Trustee or such Holder may have
pursuant to Section 1302, such payment or distribution shall be paid over or
delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee, agent or other Person making payment or distribution of
asset of the Guarantor for payment in accordance with subsection (b).

          (d) Subject to the payment in full of all General Obligations, the
Holders of the Securities shall be subrogated (equally and ratably with the
holders of all indebtedness of the Guarantor that by its express terms provides
for the payment over of amounts corresponding to Excess Proceeds to creditors in
respect of General Obligations and is entitled to like rights of subrogation) to
the rights of the creditors in respect of General Obligations to receive
payments and distributions of cash, property and securities applicable to the
General Obligations until all amounts due with respect to the Guarantees shall
be paid in full. For purposes of such

                                      -91-
<PAGE>

subrogation, no payments or distributions to creditors in respect of General
Obligations of any cash, property or securities to which Holders of the
Securities or the Trustee would be entitled except for the provisions of this
Section, and no payments over pursuant to the provisions of this Section to
creditors in respect of General Obligations by Holders of Securities or the
Trustee, shall, as among the Guarantor, its creditors other than creditors in
respect of General Obligations and the Holders of Securities be deemed to be a
payment or distribution by the Guarantor to or on account of the General
Obligations.

          (e) The provisions of subsections (b), (c) and (d) of this Section are
and are intended solely for the purpose of defining the relative rights of the
Holders of the Securities with respect to the Guarantees, on the one hand, and
the creditors in respect of General Obligations, on the other hand, after giving
effect to the rights of the holders of Senior Indebtedness, as provided in this
Article. Nothing contained in subsections (b), (c) and (d) of this Section is
intended to or shall affect the relative rights against the Guarantor or the
Holders of the Securities and (1) the holders of Senior Indebtedness or (2)
other creditors of the Guarantor other than creditors in respect of General
Obligations.

SECTION 1316. AUTOMATIC TERMINATION.

          Upon the occurrence of a Termination Event, the Guarantor will
promptly notify the Trustee and the following provisions of this Indenture shall
immediately and automatically terminate, be null and void ab initio and have no
further effect: the definitions of "claim", "Excess Proceeds" and "General
Obligations"; subsection (d) of Section 111; the third paragraph of Section 203;
the last paragraph of Section 1001; subsection (b) of Section 1007; all language
in each parenthetical containing the words "General Obligations" in Sections
1307, 1310, 1311, 1313 and 1313; and Section 1315. The Trustee shall have the
right at any time to request that the Guarantor supply it with an Opinion of
Counsel as to whether a Termination Event shall have occurred.
