</TABLE>

(1)  An indeterminate principal amount or number of debt securities, common
     stock and/or preferred stock, depositary shares or warrants of Beckman
     Coulter as may from time to time be issued at indeterminate prices, in
     United States dollars or the equivalent thereof in any other currency,
     composite currency or currency unit, as shall result in an aggregate
     initial offering price for all securities in an amount not to exceed
     $500,000,000.

(2)  This amount represents the principal amount of any debt securities issued
     at their principal amount, the issue price of any debt securities issued at
     an original issue discount, the issue price of any preferred stock and
     preferred securities and the amount computed pursuant to Rule 457(c) for
     any common stock.

(3)  Estimated solely for the purpose of calculating the registration fee, which
     is calculated in accordance with Rule 457(o) of the rules and regulations
     under the Securities Act of 1933. Rule 457(o) permits the registration fee
     to be calculated on the basis of the maximum offering price of all of the
     securities listed and, therefore, the table does not specify by each class
     information as to the amount to be registered, the proposed maximum
     offering price per unit or the proposed maximum aggregate offering price.

(4)  Pursuant to Rule 429 under the Securities Act, $100,000,000 aggregate
     principal amount of securities previously registered on Form S-3 (File No.
     333-02317) are being carried forward under this registration statement. A
     filing fee of $34,483 was paid on April 5, 1996 in connection with those
     securities.

(5)  This registration statement also covers such indeterminate number of
     securities that may be issued upon exchange for, or upon conversion of, as
     the case may be, the securities registered hereunder.

(6)  The Rights are initially carried and traded with the common stock. The
     value attributable to the Rights, if any, is reflected in the value of the
     common stock.


   THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL
FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a) OF
THE SECURITIES ACT OF 1933 OR UNTIL THIS REGISTRATION STATEMENT SHALL BECOME
EFFECTIVE ON SUCH DATE AS THE SEC, ACTING PURSUANT TO SAID SECTION 8(a), MAY
DETERMINE.

                              ABOUT THIS PROSPECTUS

        This prospectus is part of a "shelf" registration statement that we
filed with the United States Securities and Exchange Commission, or the "SEC."
By using a shelf registration statement, we may sell up to $500,000,000 offering
price of any combination of the securities described in this prospectus from
time to time and in one or more offerings. This prospectus only provides you
with a general description of the securities that we may offer. Each time we
sell securities, we will provide a supplement to this prospectus that contains
specific information about the terms of the securities. The supplement may also
add, update or change information contained in this prospectus. Before
purchasing any securities, you should carefully read both this prospectus and
any supplement, together with the additional information described under the
heading "Where You Can Find More Information."

        You should rely only on the information contained or incorporated by
reference in this prospectus and in any supplement. We have not authorized any
other person to provide you with different information. If anyone provides you
with different or inconsistent information, you should not rely on it. We will
not make an offer to sell these securities in any jurisdiction where the offer
or sale is not permitted. You should assume that the information appearing in
this prospectus and the supplement to this prospectus is accurate as of the
dates on their covers. Our business, financial condition, results of operations
and prospects may have changed since that date.

        When we refer to "we," "our" and "us" in this prospectus, we mean
Beckman Coulter, Inc., excluding, unless the context otherwise requires or as
otherwise expressly stated, our subsidiaries. When we refer to "you" or "yours,"
we mean the holders of the applicable series of securities.

                 INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

        The rules of the SEC allow us to "incorporate by reference" information

and later information that we file with the SEC will automatically update and
supersede that information. The prospectus incorporates by reference the
documents set forth below that we have previously filed with the SEC. These
documents contain important information about us.

        -  Our Annual Report on Form 10-K filed with the SEC on March 6, 2000;

                           FORWARD-LOOKING STATEMENTS

        This prospectus, including the documents that we incorporate by
reference, contains "forward-looking statements" within the meaning of Section
27A of the Securities Act and Section 21E of the Securities Exchange Act of
1934, as amended (the "Exchange Act"). Such statements are indicated by words or
phrases such as "anticipate," "estimate," "plans," "projects," "continuing,"
"ongoing," "expects," "management believes," "we believe," "we intend" and
similar words or phrases. We have based these forward-looking statements on our
current expectations and projections about future events. These forward-looking
statements are subject to risks, uncertainties, and assumptions about us and our
subsidiaries, including, among other things, factors discussed in our filings
with the SEC and the following:

        -  the effect of economic, credit and capital market conditions in
           general and on companies engaged in the clinical diagnostic and life
           science research markets in particular;

        -  the impact of competition;

        -  changes in laws or regulations, third party relations and approvals
           and decisions of courts, regulators and governmental bodies; and

        -  changes in customer demand.

those included in or contemplated or implied by such statements.

                                 BECKMAN COULTER

        Beckman Coulter simplifies and automates laboratory processes used in
all phases of the battle against disease. We design, manufacture and market
systems which consist of instruments, chemistries, software and supplies that
meet a variety of laboratory needs. Our products are used in a range of
applications, from instruments used for pioneering medical research and drug
discovery to diagnostic tools found in hospitals and physicians' offices. We
compete in market segments that total approximately $27 billion in annual sales
worldwide.

        Our product lines include virtually all blood tests routinely performed
in hospital laboratories and a range of systems for medical and pharmaceutical
research. We have approximately 125,000 systems operating in laboratories around
the world, with 68% of annual revenues coming from after-market customer
purchases of operating supplies, chemistry kits, and service. We market our
products in approximately 130 countries, generating nearly 45% of revenues
outside the United States.

        The two primary segments which we serve are the clinical diagnostics
market and the life science research market. Clinical diagnostics encompasses
the detection and monitoring of disease by means of laboratory evaluation and
analysis of bodily fluids, cells and other substances from patients. Our
clinical diagnostics customers include hospital clinical laboratories,
physicians' offices and group practices, and commercial reference laboratories
(large central laboratories to which hospitals and physicians refer tests). Life
science research is the study of the characteristics, behavior and structure of
living organisms and their component systems. Our life science research
customers include universities conducting academic research, medical research
laboratories, pharmaceutical companies and biotechnology firms.

        Our principal executive offices are located at 4300 N. Harbor Boulevard,
Fullerton, California 92835, and our telephone number is (714) 871-4848.


                                 USE OF PROCEEDS

        We intend to use the net proceeds from the sale of the securities for
general corporate purposes, including repaying, redeeming or repurchasing
existing debt, and for working capital, capital expenditures and other
acquisitions. We may invest funds not required immediately for such purposes in
short-term investment grade securities.

                       RATIO OF EARNINGS TO FIXED CHARGES

        Our ratios of earnings to fixed charges are as follows for the periods
indicated:

                                       3
<PAGE>   8

        We have computed the ratio of earnings to fixed charges by dividing
earnings (loss) before income taxes and fixed charges by fixed charges. Fixed
charges consist of interest expense and a portion of rent expense deemed
representative of the interest factor.

the "indentures" and individually referred to as an "indenture." The trustee
under each indenture is referred to as the "indenture trustee." The indentures
are subject to and governed by the Trust Indenture Act of 1939, and may be
supplemented or amended from time to time following their execution.


                         DESCRIPTION OF DEBT SECURITIES

        The following description discusses the general terms and provisions of
the debt securities that we may offer by this prospectus. The debt securities
may be issued as senior debt securities or subordinated debt securities. The
indebtedness represented by the senior debt securities will rank equally with
all of our other unsecured and unsubordinated debt. The indebtedness represented
by the subordinated debt securities will rank junior and be subordinate in right
of payment to the prior payment in full of our senior debt, to the extent and in
the manner set forth in the prospectus supplement for the securities. See
"--Subordination" below.

        Each indenture gives us broad authority to set the particular terms of
each series of debt securities, including the right to modify certain of the
terms contained in the indenture. The particular terms of a series of debt
securities and the extent, if any, to which the particular terms of the issue
modify the terms of the indenture will be described in the prospectus supplement
relating to the debt securities.

        Each indenture contains the full legal text of the matters described in
this section. Because this section is a summary, it does not describe every
aspect of the debt securities or the applicable indenture. This summary is
subject to and qualified in its entirety by reference to all the provisions of
the applicable indenture, including definitions of terms used in the indenture.
We also include references in parentheses to certain sections of the indentures.
Whenever we refer to particular sections or defined terms of the indentures in
this prospectus or in a prospectus supplement, these sections or defined terms
are incorporated by reference herein or in the prospectus supplement. This
summary also is subject to and qualified by reference to the description of the
particular terms of the debt securities in the applicable prospectus supplement.



                                       4

GENERAL

        We may issue an unlimited amount of debt securities under each indenture
in one or more series. We need not issue all debt securities of one series at
the same time and, unless otherwise provided, we may reopen a series, without
the consent of the holders of the debt securities of that series, for issuances
of additional debt securities of that series.

        The debt securities will be unsecured obligations.

        Prior to the issuance of each series of debt securities, the terms of
the particular securities will be specified in a supplemental indenture
(including any pricing supplement) and a board resolution of Beckman Coulter or
in one or more officer's certificates of Beckman Coulter pursuant to a
supplemental indenture or a board resolution. We refer you to the applicable
prospectus supplement for a description of the following terms of the series of
debt securities:

        (a) the title of the debt securities;

        (b) any limit upon the principal amount of the debt securities;

        (c) the date or dates on which principal will be payable or how to
determine the dates;

        (d) the rate or rates or method of determination of interest; the date
from which interest will accrue; the dates on which interest will be payable,
which we refer to as the "interest payment dates;" and any record dates for the
interest payable on the interest payment dates;

        (e) any obligation or option of Beckman Coulter to redeem, purchase or
repay debt securities, or any option of the registered holder to require Beckman
Coulter to redeem or repurchase debt securities, and the terms and conditions
upon which the debt securities will be redeemed, purchased or repaid;

        (f) the denominations in which the debt securities will be issuable (if
other than denominations of $1,000 and any integral multiple thereof);

        (g) any provision relating to deferral of interest payments;

        (h) whether the debt securities are to be issued in whole or in part in
the form of one or more global debt securities and, if so, the identity of the
depositary for the global debt securities; and

        (i) any other terms of the debt securities. (See Section 301.)

PAYMENT OF DEBT SECURITIES--INTEREST

        Unless indicated differently in a prospectus supplement, we will pay
interest on the debt security on each interest payment date to the person in
whose name the debt security is registered as of the close of business on the
regular record date relating to the interest payment date.

        However, if we default in paying interest on a debt security, we will
pay defaulted interest in either of the two following ways:

        (a) We will first propose to the indenture trustee a payment date for
the defaulted interest. Next, the indenture trustee will choose a special record
date for determining which registered holders are entitled to the payment. The
special record date will be between 10 and 15 days before the payment date we
propose. Finally, we will pay the defaulted interest on the payment date to the
registered holder of the debt security as of the close of business on the
special record date.



                                       5
<PAGE>   10

        (b) Alternatively, we can propose to the indenture trustee any other
lawful manner of payment that is consistent with the requirements of any
securities exchange on which the debt securities are listed for trading. If the
indenture trustee thinks the proposal is practicable, payment will be made as
proposed. (See Section 307.)

PAYMENT OF DEBT SECURITIES--PRINCIPAL

        Unless we indicate differently in a prospectus supplement, we will pay
principal of and any premium on the debt securities at stated maturity, upon
redemption or otherwise, upon presentation of the debt securities at the office
of the indenture trustee, as our paying agent. Any other paying agent initially
designated for the debt securities of a particular series will be named in the
applicable prospectus supplement.

        In our discretion, we may change the place of payment on the debt
securities, and may remove any paying agent and may appoint one or more
additional paying agents. (See Section 1002.)

FORM; TRANSFERS; EXCHANGES

        The debt securities will be issued

        (a) only in fully registered form;

        (b) without interest coupons; and

        (c) unless otherwise specified in a prospectus supplement, in
denominations that are integral multiples of $1,000.

        You may have your debt securities divided into debt securities of
smaller denominations (of at least $1,000) or combined into debt securities of
larger denominations, as long as the total principal amount is not changed. This
is called an "exchange."

        You may exchange or transfer debt securities at the office of the
indenture trustee. The indenture trustee acts as our agent for registering debt
securities in the names of holders and transferring debt securities. We may
appoint another agent or act as our own agent for this purpose. The entity
performing the role of maintaining the list of registered holders is called the
"security registrar." It will also perform transfers.

        In our discretion, we may change the place for registration of transfer
of the debt securities and may remove and/or appoint one or more additional
security registrars. (See Sections 305 and 1002.)

        Except as otherwise provided in a prospectus supplement, there will be
no service charge for any transfer or exchange of the debt securities, but you
may be required to pay a sum sufficient to cover any tax or other governmental
charge payable in connection with the transfer or exchange. We may block the
transfer or exchange of (a) debt securities during a period of 15 days prior to
giving any notice of redemption or (b) any debt security selected for redemption
in whole or in part, except the unredeemed portion of any debt security being
redeemed in part. (See Section 305.)

REDEMPTION

        We will set forth any terms for the redemption of debt securities in a
prospectus supplement. Unless we indicate differently in a prospectus
supplement, and except with respect to debt securities redeemable at the option
of the registered holder, debt securities will be redeemable upon notice by mail
between 30 and 60 days prior to the redemption date. If less than all of the
debt securities of any series or any tranche of a series are to be redeemed, the
indenture trustee will select the debt securities to be redeemed. In the absence
of any



                                       6
<PAGE>   11

provision for selection, the indenture trustee will choose a method of random
selection it deems fair and appropriate. (See Sections 1102, 1103 and 1104.)

        Debt securities will cease to bear interest on the redemption date. We
will pay the redemption price and any accrued interest once you surrender the
debt security for redemption. (See Section 1105.) If only part of a debt
security is redeemed, the indenture trustee will deliver to you a new debt
security of the same series for the remaining portion without charge. (Section
1106.)

        We may make any redemption conditional upon the receipt by the paying
agent, on or prior to the date fixed for redemption, of money sufficient to pay
the redemption price. If the paying agent has not received the money by the date
fixed for redemption, we will not be required to redeem the debt securities.
(See Section 1104.)

EVENTS OF DEFAULT

        An "event of default" occurs with respect to debt securities of any
series if:

        (a) we do not pay any interest on any debt securities of the applicable
series within 30 days of the due date (following any deferral allowed under the
terms of the debt securities and elected by us);

        (b) we do not pay principal or premium on any debt securities of the
applicable series on its due date;

        (c) we remain in breach of a covenant or warranty (excluding covenants
and warranties not applicable to the affected series) of the indenture for 90
days after we receive a written notice of default stating we are in breach and
requiring remedy of the breach; the notice must be sent by either the indenture
trustee or registered holders of at least 25% of the principal amount of debt
securities of the affected series;

        (d) we file for bankruptcy or other specified events in bankruptcy,
insolvency, receivership or reorganization occur; or

        (e) any other event of default specified in the prospectus supplement
occurs. (See Section 501.)

        No event of default with respect to a series of debt securities
necessarily constitutes an event of default with respect to the debt securities
of any other series issued under the indenture.

REMEDIES

    Acceleration

        If an event of default occurs and is continuing with respect to any
series of debt securities, then either the indenture trustee or the registered
holders of not less than 25% in principal amount of the outstanding debt
securities of that series may declare the principal amount of all of the debt
securities of that series to be due and payable immediately. (See Section 502.)

    Rescission of Acceleration

        After the declaration of acceleration has been made and before the
indenture trustee has obtained a judgment or decree for payment of the money due
on any series of debt securities, the registered holders of not less than a
majority in aggregate principal amount of the outstanding debt securities of
that series may rescind and annul the declaration and its consequences, if

        (a) we pay or deposit with the indenture trustee a sum sufficient to pay

               (1)  all overdue interest;



                                       7
<PAGE>   12

               (2)  the principal of and any premium which have become due other
                    than by the declaration of acceleration and overdue interest
                    on these amounts;

               (3)  interest on overdue interest to the extent lawful;

               (4)  all amounts due to the indenture trustee under the
                    indenture; and

        (b) all events of default with respect to the affected series, other
than the nonpayment of the principal which has become due solely by the
declaration of acceleration, have been cured or waived as provided in the
indenture. (See Section 502.)

        For more information as to waiver of defaults, see "Waiver of Default
and of Compliance" below.

    Control by Registered Holders; Limitations

        Subject to the indenture, if an event of default with respect to the
debt securities of any series occurs and is continuing, the registered holders
of a majority in principal amount of the outstanding debt securities of that
series will have the right to

        (a) direct the time, method and place of conducting any proceeding for
any remedy available to the indenture trustee, or

        (b) exercise any trust or power conferred on the indenture trustee with
respect to the debt securities of the series.

        If an event of default is continuing with respect to all the series of
debt securities, the registered holders of a majority in aggregate principal
amount of the outstanding debt securities of all the series, considered as one
class, will have the right to make such direction, and not the registered
holders of the debt securities of any one of the series. These rights of
registered holders to make direction are subject to the following limitations:

        (a) the registered holders' directions will not conflict with any law or
the indenture; and

        (b) the registered holders' directions may not involve the indenture
trustee in personal liability where the indenture trustee believes indemnity is
not adequate.

        The indenture trustee may also take any other action it deems proper
which is consistent with the registered holders' direction. (See Sections 512
and 603.)

        In addition, the indenture provides that no registered holder of any
debt security of any series will have any right to institute any proceeding,
judicial or otherwise, with respect to the indenture for the appointment of a
receiver or for any other remedy under the indenture unless:

        (a) that registered holder has previously given the indenture trustee
written notice of a continuing event of default;

        (b) the registered holders of not less than 25% in aggregate principal
amount of the outstanding debt securities of all the series, considered as one
class, or, in the case of an event of default of the character specified above
in clause (a) or (b) under "Events of Default," that series, have made written
request to the indenture trustee to institute proceedings in respect of that
event of default and have offered the indenture trustee indemnity satisfactory
to it against costs and liabilities incurred in complying with the request; and

        (c) for 60 days after receipt of the notice, the indenture trustee has
failed to institute a proceeding and no direction inconsistent with the request
has been given to the indenture trustee during the 60-day period by



                                       8
<PAGE>   13

the registered holders of a majority in aggregate principal amount of
outstanding debt securities of all the series, considered as one class, or, in
the case of an event of default of the character specified above in clause (a)
or (b) under "Events of Default," that series.

        Furthermore, no registered holder will be entitled to institute any
action if and to the extent that the action would disturb or prejudice the
rights of other registered holders. (See Sections 507 and 603.)

        However, each registered holder has an absolute and unconditional right
to receive payment when due and to bring a suit to enforce that right. (See
Sections 507 and 508.)

NOTICE OF DEFAULT

        The indenture trustee is required to give the registered holders of the
debt securities notice of any default under the indenture to the extent required
by the Trust Indenture Act, unless the default has been cured or waived; except
that in the case of an event of default of the character specified above in
clause (c) under "Events of Default," no notice shall be given to the registered
holders until at least 30 days after the occurrence thereof. (See Section 602.)
The Trust Indenture Act currently permits the indenture trustee to withhold
notices of default (except for certain payment defaults) if the indenture
trustee in good faith determines the withholding of the notice to be in the
interests of the registered holders.

        We will furnish the indenture trustee with an annual statement as to our
compliance with the conditions and covenants in the indenture. (See Section
1005.)

WAIVER OF DEFAULT AND OF COMPLIANCE

        The registered holders of a majority in aggregate principal amount of
the outstanding debt securities of all affected series (voting as one class) may
waive, on behalf of the registered holders of all debt securities of all such
series, any past default under the indenture, except a default in the payment of
principal, premium or interest, or with respect to compliance with certain
provisions of the indenture that cannot be amended without the consent of the
registered holder of each outstanding debt security. (See Section 513.)

        Compliance with some of the covenants in the indenture or otherwise
provided with respect to debt securities may be waived by the registered holders
of a majority in aggregate principal amount of the affected debt securities,
considered as one class. (See Section 1006.)

CONSOLIDATION, MERGER AND CONVEYANCE OF ASSETS AS AN ENTIRETY; NO FINANCIAL
COVENANTS

        Subject to the provisions described in the next paragraph, we will
preserve our corporate existence. (See Section 1004.)

        We have agreed not to consolidate with or merge into any other entity
and not to convey, transfer or lease our properties and assets substantially as
an entirety to any entity, unless:

        (a) the entity formed by the consolidation or into which we are merged,
or the entity which acquires us or which leases our property and assets
substantially as an entirety, is an entity organized and existing under the laws
of the United States of America or any State of the United States or the
District of Columbia, and expressly assumes, by supplemental indenture, the due
and punctual payment of the principal, premium and interest on all the
outstanding debt securities and the performance of all of our covenants under
the indenture, and

        (b) immediately after giving effect to the transactions, no event of
default, and no event which after notice or lapse of time or both would become
an event of default, will have occurred and be continuing. (See Section 801.)



                                       9
<PAGE>   14

        The indenture contains no financial or other similar restrictive
covenants. Any such covenants with respect to any particular series of debt
securities will be set forth in the applicable prospectus supplement.

MODIFICATION OF INDENTURE

        Without Registered Holder Consent. Without the consent of any registered
holders of debt securities, we and the applicable indenture trustee may enter
into one or more supplemental indentures for any of the following purposes:

        (a) to evidence the succession of another entity to us; or

        (b) to add one or more covenants or other provisions for the benefit of
the registered holders of all or any series or tranche of debt securities, or to
surrender any right or power conferred upon us; or

        (c) to add any additional events of default for all or any series of
debt securities; or

        (d) to change or eliminate any provision of the indenture or to add any
new provision to the indenture that does not adversely affect the interests of
the registered holders; or

        (e) to provide security for the debt securities of any series; or

        (f) to establish the form or terms of debt securities of any series or
tranche or any debt securities guarantees as permitted by the indenture; or

        (g) to provide for the issuance of bearer securities; or

        (h) to evidence and provide for the acceptance of appointment of a
separate or successor indenture trustee; or

        (i) to provide for the procedures required to permit the utilization of
a noncertificated system of registration for any series or tranche of debt
securities; or

        (j) to change any place or places where

               (1)  we may pay principal, premium and interest,

               (2)  debt securities may be surrendered for transfer or exchange,
                    or

               (3)  notices and demands to or upon us may be served; or

        (k) to cure any ambiguity, defect or inconsistency or to make any other
changes that do not adversely affect the interests of the registered holders in
any material respect.
(See Section 901.)

        If the Trust Indenture Act is amended after the date of the indenture so
as to require changes to the indenture or so as to permit changes to, or the
elimination of, provisions which, at the date of the indenture or at any time
thereafter, were required by the Trust Indenture Act to be contained in the
indenture, the indenture will be deemed to have been amended so as to conform to
the amendment or to effect the changes or elimination, and Beckman Coulter and
the applicable indenture trustee may, without the consent of any registered
holders, enter into one or more supplemental indentures to effect or evidence
the amendment.

        With Registered Holder Consent. We and the indenture trustee may, with
some exceptions, amend or modify any indenture with the consent of the
registered holders of at least a majority in aggregate principal amount of the
debt securities of all series affected by the amendment or modification (voting
as one class).



                                       10
<PAGE>   15

However, no amendment or modification may, without the consent of the registered
holder of each outstanding debt security affected thereby,

        (a) change the stated maturity of the principal or interest on any debt
security (other than pursuant to the terms of the debt security), or reduce the
principal amount, interest or premium payable or change the currency in which
any debt security is payable, or impair the right to bring suit to enforce any
payment;

        (b) reduce the percentages of registered holders whose consent is
required for any supplemental indenture or waiver or reduce the requirements for
quorum and voting under the indenture; or

        (c) modify certain of the provisions in the indenture relating to
supplemental indentures and waivers of certain covenants and past defaults.

        A supplemental indenture which changes or eliminates any provision of
the indenture expressly included solely for the benefit of registered holders of
debt securities of one or more particular series or tranches will be deemed not
to affect the rights under the indenture of the registered holders of debt
securities of any other series or tranche. (See Section 902.)

MISCELLANEOUS

        The indenture provides that some debt securities, including those for
which payment or redemption money has been deposited or set aside in trust, will
not be deemed to be "outstanding" in determining whether the registered holders
of the requisite principal amount of the outstanding debt securities have given
or taken any demand, direction, consent or other action under the indenture as
of any date, or are present at a meeting of registered holders for quorum
purposes. (See Section 101.)

        We will be entitled to set any day as a record date for the purpose of
determining the registered holders of outstanding debt securities of any series
entitled to give or take any demand, direction, consent or other action under
the indenture, in the manner and subject to the limitations provided in the
indenture. In some circumstances, the indenture trustee also will be entitled to
set a record date for action by registered holders. If a record date is set for
any action to be taken by registered holders of particular debt securities, the
action may be taken only by persons who are registered holders of the respective
debt securities on the record date. (See Section 104.)

DEFEASANCE AND COVENANT DEFEASANCE

        The indentures provide, unless the terms of the particular series of
debt securities provide otherwise, that we may, upon satisfying several
conditions, cause ourselves to be:

        (a) discharged from our obligations, with some exceptions, with respect
to any series of debt securities, which we refer to as "defeasance"; and

        (b) released from our obligations under specified covenants with respect
to any series of debt securities, which we refer to as "covenant defeasance."

        One condition we must satisfy is the irrevocable deposit with the
indenture trustee, in trust, of money and/or government obligations which,
through the scheduled payment of principal and interest on those obligations,
would provide sufficient moneys to pay the principal of and any premium and
interest on those debt securities on the maturity dates of the payments or upon
redemption.

        The indentures permit defeasance with respect to any series of debt
securities even if a prior covenant defeasance has occurred with respect to the
debt securities of that series. Following a defeasance, payment of the debt
securities defeased may not be accelerated because of an event of default.
Following a covenant



                                       11
<PAGE>   16

defeasance, payment of the debt securities may not be accelerated by reference
to the specified covenants affected by the covenant defeasance. However, if an
acceleration were to occur, the realizable value at the acceleration date of the
money and government obligations in the defeasance trust could be less than the
principal and interest then due on the respective debt securities, since the
required deposit in the defeasance trust would be based upon scheduled cash
flows rather than market value, which would vary depending upon interest rates
and other factors.

        Under current United States federal income tax law, the defeasance
contemplated in the preceding paragraphs would be treated as an exchange of the
relevant debt securities in which holders of the debt securities might recognize
gain or loss. In addition, the amount, timing and character of amounts that
holders would be required after the defeasance to include in income might be
different from that which would be includible in the absence of the defeasance.
Prospective investors are urged to consult their own tax advisors as to the
specific consequences of a defeasance, including the applicability and effect of
tax laws other than United States federal income tax laws.

        Under current United States federal income tax laws, unless accompanied
by other changes in the terms of the debt securities, covenant defeasance
generally should not be treated as a taxable exchange.

RESIGNATION AND REMOVAL OF THE INDENTURE TRUSTEE; DEEMED RESIGNATION

        The indenture trustee may resign at any time by giving written notice to
us.

        The indenture trustee may also be removed by act of the registered
holders of a majority in principal amount of the then outstanding debt
securities of any series.

        No resignation or removal of the indenture trustee and no appointment of
a successor indenture trustee will become effective until the acceptance of
appointment by a successor indenture trustee in accordance with the requirements
of the indenture.

        Under some circumstances, we may appoint a successor indenture trustee
and, if the successor accepts, the indenture trustee will be deemed to have
resigned. (Section 610).

SUBORDINATION

        Unless we indicate differently in a prospectus supplement, any
subordinated debt securities will be subordinated in the following manner. If
our assets are distributed upon our dissolution, winding up, liquidation or
reorganization, the payment of the principal of, premium, if any, and interest
on any subordinated debt securities will be subordinated, to the extent provided
in the subordinated indenture and the applicable supplemental indenture, to the
prior payment in full of all senior indebtedness, including senior debt
securities. However, our obligation to pay principal, and premium, if any, or
interest on the subordinated debt securities will not otherwise be affected. No
payment on account of principal, or premium, if any, sinking fund or interest
may be made on the subordinated debt securities at any time when there is a
default in the payment of principal, premium, if any, sinking fund or interest
on senior indebtedness. If, while we are in default on senior indebtedness, any
payment is received by the indenture trustee under the subordinated debt
security indenture or the holders of any of the subordinated debt securities
before we have paid all senior indebtedness in full, the payment or distribution
must be paid over to the holders of the unpaid senior indebtedness or applied to
the repayment of the unpaid senior indebtedness. Subject to paying the senior
indebtedness in full, the holders of the subordinated debt securities will be
subrogated to the rights of the holders of the senior indebtedness to the extent
that payments are made to the holders of senior indebtedness out of the
distributive share of the subordinated debt securities.

        Due to the subordination, if our assets are distributed upon insolvency,
some or all of our general creditors may recover more, ratably, than holders of
subordinated debt securities. The subordinated indenture



                                       12
<PAGE>   17

or applicable supplemental indenture may state that its subordination provisions
will not apply to money and securities held in trust under the satisfaction and
discharge, and the legal defeasance provisions of the subordinated indenture.

        If this prospectus is being delivered in connection with the offering of
a series of subordinated debt securities, the accompanying prospectus supplement
or the information incorporated by reference in it will set forth the
approximate amount of senior indebtedness outstanding as of a recent date.

CONVERSION RIGHTS

        The terms and conditions of any debt securities being offered that are
convertible into our common stock will be set forth in a prospectus supplement.
These terms will include the conversion price, the conversion period, provisions
as to whether conversion will be mandatory, or at the option of the holder or
us, the events requiring an adjustment of the conversion price and provisions
affecting conversion in the event that the debt securities are redeemed.

                                 DESCRIPTION OF
                        COMMON STOCK AND PREFERRED STOCK

        The following description of our common stock and preferred stock is
only a summary and is qualified in its entirety by reference to our certificate
of incorporation and bylaws. Therefore, you should read carefully the more
detailed provisions of our Fifth Restated Certificate of Incorporation, our
Amended and Restated Bylaws, and our Stockholder Protection Rights Agreement,
dated February 4, 1999, between us and First Chicago Trust Company of New York,
as rights agent, copies of which are incorporated by reference as exhibits to
the registration statement of which this prospectus is a part.

GENERAL

        This prospectus describes certain general terms of our capital stock.
For a more detailed description of these securities, we refer you to the
applicable provisions of Delaware law and our Fifth Restated Certificate of
Incorporation (the "Restated Certificate"). When we offer to sell a particular
series of these securities, we will describe the specific terms of the series in
a supplement to this prospectus. Accordingly, for a description of the terms of
any series of securities, you must refer to both the prospectus supplement
relating to that series and the description of the securities set forth in this
prospectus. A prospectus supplement may change any of the terms of the
securities described in this prospectus.

        Pursuant to our Restated Certificate, our authorized capital stock
consists of 150,000,000 shares of common stock, par value $0.10 per share, and
10,000,000 shares of preferred stock, par value $0.10 per share. At May 1,
2000, we had 29,358,170 shares of common stock outstanding and no shares of
preferred stock outstanding.

COMMON STOCK

        Subject to any preferential rights that our board of directors may grant
in connection with the future issuance of preferred stock, each holder of common
stock is entitled to one vote per share on all matters voted upon by the
stockholders. Each holder of common stock is entitled to receive ratably any
dividends declared on the common stock by the board of directors from funds
legally available for distribution. In the event of



                                       13
<PAGE>   18

our liquidation, dissolution or winding up, after we pay all debts and other
liabilities and any liquidation preference on the preferred stock, each holder
of common stock would be entitled to share ratably in all of our remaining
assets. The common stock has no subscription, redemption, conversion or
preemptive rights. All shares of common stock are fully paid and nonassessable.

        DELAWARE GENERAL CORPORATION LAW SECTION 203

        As a corporation organized under the laws of the State of Delaware, we
are subject to Section 203 of the General Corporation Law of the State of
Delaware (the "DGCL"), which restricts certain business combinations between us
and an "interested stockholder" (in general, a stockholder owning 15% or more of
our outstanding voting stock) or that stockholder's affiliates or associates for
a period of three years following the date on which the stockholder becomes an
"interested stockholder." The restrictions do not apply if:

        -  prior to an interested stockholder becoming such, our board of
           directors approves either the business combination or the transaction
           in which the stockholder becomes an interested stockholder;

        -  upon consummation of the transaction in which the stockholder becomes
           an interested stockholder, the interested stockholder owns at least
           85% of our voting stock outstanding at the time the transaction
           commenced, subject to certain exceptions; or

        -  on or after the date an interested stockholder becomes such, the
           business combination is both approved by our board of directors and
           authorized at an annual or special meeting of our stockholders (and
           not by written consent) by the affirmative vote of at least 662/3% of
           the outstanding voting stock not owned by the interested stockholder.

PREFERRED STOCK

        Under the Restated Certificate, our board of directors is authorized
generally without stockholder approval to issue shares of preferred stock from
time to time, in one or more classes or series. Prior to the issuance of shares
of each series, the board of directors is required by the DGCL and the Restated
Certificate to adopt resolutions and file a certificate of designation with the
Secretary of State of the State of Delaware. The certificate of designation
fixes for each class or series the designations, powers, preferences, rights,
qualifications, limitations and restrictions, including, but not limited to, the
following:

        -  the number of shares constituting each class or series;

        -  voting rights;

        -  rights and terms of redemption (including sinking fund provisions);

        -  dividend rights and rates;

        -  dissolution;

        -  terms concerning the distribution of assets;

        -  conversion or exchange terms;

        -  redemption prices; and

        -  liquidation preferences.



                                       14
<PAGE>   19

        All shares of preferred stock offered hereby will, when issued, be fully
paid and nonassessable and will not have any preemptive or similar rights. Our
board of directors could authorize the issuance of shares of preferred stock
with terms and conditions which could have the effect of discouraging a takeover
or other transaction that might involve a premium price for holders of the
shares or which holders might believe to be in their best interests.

        We will set forth in a prospectus supplement relating to the class or
series of preferred stock being offered the following terms:

        -  The title and stated value of the preferred stock;

        -  The number of shares of the preferred stock offered, the liquidation
           preference per share and the offering price of the preferred stock;

        -  The dividend rate(s), period(s) and/or payment date(s) or method(s)
           of calculation applicable to the preferred stock;

        -  Whether dividends are cumulative or non-cumulative and, if
           cumulative, the date from which dividends on the preferred stock will
           accumulate;

        -  The procedures for any auction and remarketing, if any, for the
           preferred stock;

        -  The provisions for a sinking fund, if any, for the preferred stock;

        -  The provision for redemption, if applicable, of the preferred stock;

        -  Any listing of the preferred stock on any securities exchange;

        -  The terms and conditions, if applicable, upon which the preferred
           stock will be convertible into common stock, including the conversion
           price (or manner of calculation) and conversion period;

        -  Voting rights, if any, of the preferred stock;

        -  Whether interests in the preferred stock will be represented by
           depositary shares;

        -  A discussion of any material and/or special United States Federal
           income tax considerations applicable to the preferred stock;

        -  The relative ranking and preferences of the preferred stock as to
           dividend rights and rights upon the liquidation, dissolution or
           winding up of our affairs;

        -  Any limitations on issuance of any class or series of preferred stock
           ranking senior to or on a parity with the class or series of
           preferred stock as to dividend rights and rights upon liquidation,
           dissolution or winding up of our affairs; and

        -  Any other specific terms, preferences, rights, limitations or
           restrictions of the preferred stock.

RANK

        Unless we specify otherwise in the applicable prospectus supplement, the
preferred stock will rank, with respect to dividends and upon our liquidation,
dissolution or winding up:

        -  senior to all classes or series of our common stock and to all of our
           equity securities ranking junior to the preferred stock;



                                       15
<PAGE>   20

        -  on a parity with all of our equity securities the terms of which
           specifically provide that the equity securities rank on a parity with
           the preferred stock; and

        -  junior to all of our equity securities the terms of which
           specifically provide that the equity securities rank senior to the
           preferred stock.

The term "equity securities" does not include convertible debt securities.

PARTICIPATING PREFERRED STOCK PURCHASE RIGHTS

        On February 4, 1999, our Board of Directors adopted a Stockholder
Protection Rights Agreement ("Rights Plan") and declared a dividend distribution
of one Right on each outstanding share of our common stock. Stockholders may
transfer the Rights with the common stock only until they become exercisable.

        Generally, the Rights become exercisable only if a person or group
(subject to certain exceptions stated in the Rights Plan) acquires 15% or more
of the then outstanding shares of common stock or announces a tender offer which
would result in ownership by a person or group of 15% or more of the then
outstanding shares of common stock. Each Right entitles stockholders to buy one
one-hundredth of a share of a new series of participating preferred stock at an
exercise price of $200.

        If we are acquired in a merger or other business combination
transaction, each Right entitles its holder to purchase, at the Right's then
current price, a number of common shares having a then current market value of
twice the Right's exercise price.

        Following the acquisition by a person or group of beneficial ownership
of 15% or more of our common stock (subject to certain exceptions stated in the
Rights Plan) and prior to an acquisition of 50% or more of our common stock, our
board of directors may exchange the Rights (other than Rights owned by the
person or group), in whole or in part, at an exchange ratio described in the
Rights Plan.

        Prior to the acquisition by a person or group of beneficial ownership of
15% or more of our common stock, the Rights are redeemable for $.01 per Right at
the option of the board of directors.

REGISTRAR AND TRANSFER AGENT

        EquiServe, First Chicago Trust Division, is the registrar and transfer
agent for the common stock.


                        DESCRIPTION OF DEPOSITARY SHARES

GENERAL

        We may issue depositary shares, each of which will represent a
fractional interest of a share of a particular series of preferred stock, as
specified in the applicable prospectus supplement. We will deposit with a
depositary (the "preferred stock depositary") shares of preferred stock of each
series represented by depositary shares. We will enter into a deposit agreement
(each a "deposit agreement") with the preferred stock depositary and holders
from time to time of the depositary receipts issued by the preferred stock
depositary which evidence the depositary shares ("depositary receipts"). Subject
to the terms of the deposit agreement, each owner of a depositary receipt will
be entitled, in proportion to the holder's fractional interest in the preferred
stock, to all the rights and preferences of the series of the preferred stock
represented by the depositary shares (including dividend, voting, conversion,
redemption and liquidation rights).

        Immediately after we issue and deliver the preferred stock to a
preferred stock depositary, we will cause the preferred stock depositary to
issue the depositary receipts on our behalf. You may obtain copies of the
applicable form of deposit agreement and depositary receipt from us upon
request. The statements made in



                                       16
<PAGE>   21

this section relating to the deposit agreement and the depositary receipts are
summaries of certain anticipated provisions. These summaries are not complete
and we may modify them in a prospectus supplement. For more detail we refer you
to the deposit agreement itself, which we will file as an exhibit to the
registration statement.

DIVIDENDS AND OTHER DISTRIBUTIONS

        The preferred stock depositary will distribute all cash dividends or
other cash distributions received in respect of the preferred stock to the
record holders of depositary receipts in proportion to the number of the
depositary receipts owned by the holders, subject to the obligations of holders
to file proofs, certificates and other information and to pay certain charges
and expenses to the preferred stock depositary.

        In the event of a distribution other than in cash, the preferred stock
depositary will distribute property received by it to the record holders of
depositary receipts in proportion to the number of the depositary receipts owned
by the holders, unless the preferred stock depositary determines that it is not
feasible to make the distribution, in which case the preferred stock depositary
may, with our approval, sell the property and distribute the net proceeds from
the sale to the holders.

        No distribution will be made in respect of any depositary share that
represents any preferred stock converted into other securities.

WITHDRAWAL OF STOCK

        Upon surrender of the depositary receipts at the corporate trust office
of the preferred stock depositary (unless we have previously called for
redemption or converted into other securities the related depositary shares),
the holders will be entitled to delivery at that office of the number of whole
or fractional shares of the preferred stock and any money or other property
represented by the depositary shares. Holders of depositary receipts will be
entitled to receive shares of the related preferred stock as specified in the
applicable prospectus supplement, but holders of the shares of preferred stock
will not thereafter be entitled to receive depositary shares.

REDEMPTION OF DEPOSITARY SHARES

        Whenever we redeem shares of preferred stock held by the preferred stock
depositary, the preferred stock depositary will concurrently redeem the number
of depositary shares representing shares of the preferred stock so redeemed,
provided we have paid the applicable redemption price for the preferred stock to
be redeemed plus an amount equal to any accrued and unpaid dividends to the date
fixed for redemption. The redemption price per depositary share will be equal to
the corresponding proportion of the redemption price and any other amounts per
share payable with respect to the preferred stock. If fewer than all the
depositary shares are to be redeemed, the depositary shares to be redeemed will
be selected pro rata (as nearly as may be practicable without creating
fractional depositary shares) or by any other equitable method determined by us.

        From and after the date fixed for redemption:

        -  all dividends in respect of the shares of preferred stock called for
           redemption will cease to accrue;

        -  the depositary shares called for redemption will no longer be deemed
           to be outstanding; and

        -  all rights of the holders of the depositary receipts evidencing the
           depositary shares called for redemption will cease, except the right
           to receive any moneys payable upon the redemption and any money or
           other property to which the holders of the depositary receipts were
           entitled upon redemption and surrender to the preferred stock
           depositary.



                                       17
<PAGE>   22

VOTING OF THE PREFERRED STOCK

        Upon receipt of notice of any meeting at which the holders of the
preferred stock are entitled to vote, the preferred stock depositary will mail
the information contained in the notice of meeting to the record holders of the
depositary receipts. Each record holder of these depositary receipts on the
record date (which will be the same date as the record date for the preferred
stock) will be entitled to instruct the preferred stock depositary as to the
exercise of the voting rights pertaining to the amount of preferred stock
represented by the holder's depositary shares. The preferred stock depositary
will vote the amount of preferred stock represented by the depositary shares in
accordance with the instructions, and we will agree to take all reasonable
action necessary to enable the preferred stock depositary to do so. The
preferred stock depositary will abstain from voting the amount of preferred
stock represented by the depositary shares for which it does not receive
specific instructions from the holders of depositary receipts evidencing the
depositary shares. The preferred stock depositary will not be responsible for
any failure to carry out any instruction to vote, or for the manner or effect of
any vote made, as long as the action or non-action is in good faith and does not
result from the preferred stock depositary's negligence or willful misconduct.

LIQUIDATION PREFERENCE

        If we voluntarily or involuntarily liquidate, dissolve or wind up, the
holders of each depositary receipt will be entitled to the fraction of the
liquidation preference accorded each share of preferred stock represented by the
depositary shares, as set forth in the applicable prospectus supplement.

CONVERSION OF PREFERRED STOCK

        The depositary shares, as such, are not convertible into common stock or
any of our other securities or property. Nevertheless, if we so specify in the
applicable prospectus supplement relating to an offering of depositary shares,
holders may surrender depositary receipts to the preferred stock depositary with
written instructions to the preferred stock depositary to instruct us to convert
the preferred stock represented by the depositary shares into whole shares of
common stock, other shares of our preferred stock or other shares of stock. We
have agreed that upon receipt of the instructions and any amounts payable, we
will convert the depositary shares using the same procedures as those provided
for converting preferred stock. If the depositary shares evidenced by a
depositary receipt are to be converted in part only, the preferred stock
depositary will issue a new depositary receipt(s) for any depositary shares not
converted. No fractional shares of common stock will be issued upon conversion,
and if the conversion would result in a fractional share being issued, we will
pay an amount in cash equal to the value of the fractional interest based upon
the closing price of the common stock on the last business day prior to the
conversion.

AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

        We may amend the form of depositary receipt and any provision of the
deposit agreement at any time by agreement between us and the preferred stock
depositary. However, any amendment that materially and adversely alters the
rights of the holders of depositary receipts or that would be materially and
adversely inconsistent with the rights granted to the holders of the related
preferred stock will not be effective unless the holders of at least 662/3% of
the depositary shares evidenced by the depositary receipts then outstanding
approve the amendment. No amendment will impair the right, subject to the
exceptions set forth in the depositary agreement, of any holder of depositary
receipts to surrender any depositary receipt with instructions to deliver to the
holder the related preferred stock and all money and other property, if any,
represented by the depositary receipt, except in order to comply with law. Every
holder of an outstanding depositary receipt at the time any such amendment
becomes effective will be deemed, by continuing to hold the receipt, to consent
and agree to the amendment and to be bound by the deposit agreement as amended.



                                       18
<PAGE>   23

        We may terminate the deposit agreement upon not less than 30 days' prior
written notice to the preferred stock depositary if a majority of each series of
preferred stock affected by the termination consents to the termination. Upon
termination, the preferred stock depositary will deliver or make available to
each holder of depositary receipts, upon surrender of the depositary receipts
held by the holder, the number of whole or fractional shares of preferred stock
represented by the depositary shares evidenced by the depositary receipts
together with any other property held by the preferred stock depositary with
respect to the depositary receipt.

        In addition, the deposit agreement will automatically terminate if:

        -  all outstanding depositary shares have been redeemed;

        -  there has been a final distribution of the related preferred stock in
           connection with our liquidation, dissolution or winding up and the
           distribution has been distributed to the holders of depositary
           receipts evidencing the depositary shares representing the preferred
           stock; or

        -  each share of the related preferred stock has been converted into our
           securities which are not represented by depositary shares.

CHARGES OF PREFERRED STOCK DEPOSITARY

        We will pay all transfer and other taxes and governmental charges
arising solely from the existence of the deposit agreement. In addition, we will
pay the fees and expenses of the preferred stock depositary in connection with
the performance of its duties under the deposit agreement. However, holders of
depositary receipts will pay the fees and expenses of the preferred stock
depositary for any duties requested by the holders to be performed which are
outside of those expressly provided for in the deposit agreement.

RESIGNATION AND REMOVAL OF DEPOSITARY

        The preferred stock depositary may resign at any time by delivering to
us notice of its election to do so, and we may at any time remove the preferred
stock depositary. Any such resignation or removal will take effect upon our
appointment of a successor preferred stock depositary. We must appoint a
successor preferred stock depositary within 60 days after delivery of the notice
of resignation or removal, and any preferred stock depositary must be a bank or
trust company having its principal office in the United States and having a
combined capital and surplus of at least $50,000,000.

MISCELLANEOUS

        The preferred stock depositary will forward to holders of depositary
receipts any reports and communications the preferred stock depositary receives
from us relating to the preferred stock.

        We will not be liable, nor will the preferred stock depositary be
liable, if we are prevented from or delayed in, by law or any circumstances
beyond our control, performing our obligations under the deposit agreement. Our
obligations and the obligations of the preferred stock depositary under the
deposit agreement will be limited to performing our duties in good faith and
without negligence (in the case of any action or inaction in the voting of
preferred stock represented by the depositary shares), gross negligence or
willful misconduct. We will not be obligated, nor will the preferred stock
depositary be obligated, to prosecute or defend any legal proceeding in respect
of any depositary receipts, depositary shares or shares of preferred stock
represented thereby unless satisfactory indemnity is furnished to us. We may
rely, and the preferred stock depositary may rely, on written advice of counsel
or accountants, or information provided by persons presenting shares of
preferred stock represented thereby for deposit, holders of depositary receipts
or other persons we believe in good faith to be competent to give such
information, and on documents we believe in good faith to be genuine and signed
by a proper party.



                                       19
<PAGE>   24

        In the event the preferred stock depositary receives conflicting claims,
requests or instructions from holders of depositary receipts, on the one hand,
and us, on the other hand, the preferred stock depositary will be entitled to
act on such claims, requests or instructions received from us.


                             DESCRIPTION OF WARRANTS

        We may issue warrants to purchase debt securities ("debt warrants"),
preferred stock ("preferred stock warrants"), depositary shares ("depositary

warrants ("warrants")). We may issue warrants independently or together with any
other securities we offer pursuant to a prospectus supplement and the warrants
may be attached to or separate from the securities. We will issue each series of

                                       20

office indicated in the applicable prospectus supplement. Prior to the exercise
of their debt warrants, holders of debt warrants will not have any of the rights

entitled to payments principal, premium or interest on the securities
purchasable upon the exercise.

        -  the securities for which the warrants are exercisable;

        -  the price or prices at which the warrants will be issued;

        -  the number of the warrants issued with each share of preferred stock,
           common stock or depositary share;

        -  any provisions for adjustment of the number or amount of shares of

           and the date on which the right will expire; and

        -  the maximum or minimum number of the warrants which may be exercised
           at any time.

EXERCISE OF WARRANTS

        Each warrant will entitle the holder of the warrant to purchase for cash
at the exercise price set forth in the applicable prospectus supplement the
principal amount of debt securities or shares of preferred stock, common stock
or depositary shares being offered. Holders may exercise warrants at any time up
to the close of business on the expiration date set forth in the applicable
prospectus supplement. After the close of business on the expiration date,
unexercised warrants are void.

        Holders may exercise warrants as set forth in the prospectus supplement
relating to the warrants being offered. Upon receipt of payment and the warrant
certificate properly completed and duly executed at the corporate trust office
of the warrant agent or any other office indicated in the prospectus supplement,
we will, as soon as practicable, forward the debt securities, depositary shares
or shares of preferred stock or common stock purchasable upon the exercise. If
less than all of the warrants represented by the warrant certificate are
exercised, we will issue a new warrant certificate for the remaining warrants.

                              PLAN OF DISTRIBUTION

        We may sell the securities described in this prospectus from time to
time in one or more transactions

        -  to purchasers directly;

        -  to underwriters for public offering and sale by them;

        -  through agents;

        -  through dealers; or

        -  through a combination of any of the foregoing methods of sale.

        We may distribute the securities from time to time in one or more
transactions at:

        -  a fixed price or prices, which may be changed;

        -  market prices prevailing at the time of sale;

        -  prices related to such prevailing market prices; or

        -  negotiated prices.

DIRECT SALES

        We may sell the securities directly to institutional investors or others
who may be deemed to be underwriters within the meaning of the Securities Act of
1933, as amended, with respect to any resale of the securities. A prospectus
supplement will describe the terms of any sale of securities we are offering
hereunder.

TO UNDERWRITERS

        The applicable prospectus supplement will name any underwriter involved
in a sale of securities. Underwriters may offer and sell securities at a fixed
price or prices, which may be changed, or from time to time at market prices or
at negotiated prices. Underwriters may be deemed to have received compensation
from us from sales of securities in the form of underwriting discounts or
commissions and may also receive commissions from purchasers of securities for
whom they may act as agent. Underwriters may be involved in any at the market
offering of equity securities by or on our behalf.

        Underwriters may sell securities to or through dealers, and such dealers
may receive compensation in the form of discounts, concessions or commissions
from the underwriters and/or commissions (which may be changed from time to
time) from the purchasers for whom they may act as agent.

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

THROUGH AGENTS AND DEALERS

        We will name any agent involved in a sale of securities, as well as any
commissions payable by us to such agent, in a prospectus supplement. Unless we
indicate differently in the prospectus supplement, any such agent will be acting
on a reasonable efforts basis for the period of its appointment.



                                       22
<PAGE>   27

        If we utilize a dealer in the sale of the securities being offered
pursuant to their prospectus, we will sell the securities to the dealer, as
principal. The dealer may then resell the securities to the public at varying
prices to be determined by the dealer at the time of resale.

DELAYED DELIVERY CONTRACTS

        If we so specify in the applicable prospectus supplement, we will
authorize underwriters, dealers and agents to solicit offers by certain
institutions to purchase the securities pursuant to contracts providing for
payment and delivery on future dates. Such contracts will be subject to only
those conditions set forth in the applicable prospectus supplement.

        The underwriters, dealers and agents will not be responsible for the
validity or performance of the contracts. We will set forth in the prospectus
supplement relating to the contracts the price to be paid for the securities,
the commissions payable for solicitation of the contracts and the date in the
future for delivery of the securities.

GENERAL INFORMATION

        Underwriters, dealers and agents participating in a sale of the
securities may be deemed to be underwriters as defined in the Securities Act,
and any discounts and commissions received by them and any profit realized by
them on resale of the securities may be deemed to be underwriting discounts and
commissions, under the Securities Act. We may have agreements with underwriters,
dealers and agents to indemnify them against certain civil liabilities,
including liabilities under the Securities Act, and to reimburse them for
certain expenses.

        Underwriters or agents and their associates may be customers of, engage
in transactions with or perform services for us or our affiliates in the
ordinary course of business.

        Unless we indicate differently in a prospectus supplement, we will not
list the securities on any securities exchange. The securities will be a new
issue of securities with no established trading market. Any underwriters that
purchase securities for public offering and sale may make a market in such
securities, but such underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. We make no assurance
as to the liquidity of or the trading markets for any securities.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Section 145 of the General Corporation Law of Delaware (the "DGCL")
empowers Beckman Coulter to indemnify, subject to the standards set forth
therein, any person who is a party to any action in connection with any action,
suit or proceeding brought or threatened by reason of the fact that the person
was a director, officer, employee or agent of Beckman Coulter, or is or was
serving as such with respect to another entity at the request of Beckman
Coulter. The DGCL also provides that Beckman Coulter may purchase insurance on
behalf of any such director, officer, employee or agent. Section 14 of Beckman
Coulter's Fifth Restated Certificate of Incorporation provides that Beckman
Coulter will indemnify any person to whom, and to the fullest extent,
indemnification may be required or permitted under Section 145 of the DGCL.

        Section 102(b)(7) of the DGCL enables a Delaware corporation to provide
in its certificate of incorporation for the elimination or limitation of the
personal liability of a director to the corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director. Any such provision
cannot eliminate or limit a director's liability (1) for any breach of the
director's duty of loyalty to the corporation or its stockholders; (2) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (3) under Section 174 of the DGCL (which imposes
liability on directors for unlawful payment of dividends or unlawful stock
purchase or redemption); or (4) for any transaction from which the director
derived an improper personal benefit. Section 13 of Beckman Coulter's Fifth
Restated Certificate of Incorporation eliminates the liability of a director of
Beckman Coulter to Beckman Coulter or its stockholders for monetary damages for
breach of fiduciary duty as a director to the fullest extent permitted by the
DGCL.

        Beckman Coulter carries policies of insurance which cover the individual
directors and officers of the registrant for legal liability and which would pay
on behalf of the registrant for expenses of indemnification of directors and
officers.

ITEM 17. UNDERTAKINGS

   (a) The undersigned registrant hereby undertakes:

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

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

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

               (iii) To include any material information with respect to the
        plan of distribution not previously disclosed in the registration
        statement or any material change to such information in the registration
        statement;

provided, however, that paragraphs (a)(l)(1) and (a)(l)(2) above do not apply if
the registration statement is on Form S-3 or Form S-8 and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the SEC by the
registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the registration statement.

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

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

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

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



                                      II-2

   (d) The undersigned registrant hereby undertakes to file an application for
the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act (the "Act") in
accordance with the rules and regulations prescribed by the SEC under section
305(b)(2) of the Act.

the name of BII DELAWARE INC. Pursuant to an Agreement and Plan of Merger filed

prohibits a director from serving beyond the age of 70 years.

        3. A Fourth Restated Certificate of Incorporation as of April 2, 1998

                                       1

        4. This Fifth Restated Certificate of Incorporation amends the Fourth
Restated Certificate of Incorporation to increase the aggregate number and the
number of shares of Common Stock that the Corporation shall have authority to
issue.

        5. The text of the Certificate of Incorporation as amended is set forth
in full and reads as follows:

                1. The name of the corporation is Beckman Coulter, Inc.

                2. The address of its registered office in the State of Delaware
        is National Registered Agents, Inc., 9 East Loockerman Street, in the
        City of Dover, County of Kent, Delaware 19901. The name of its
        registered agent at such address is National Registered Agents, Inc.

                3. The nature of the business or purposes to be conducted or
        promoted is:

                To engage in any lawful act or activity for which corporations
        may be organized under the General Corporation Law of Delaware.

                4. The aggregate number of shares which the corporation shall
        have authority to issue is 160,000,000, to be divided into (a)
        150,000,000 shares of Common Stock, par value $.10 per share, and (b)
        10,000,000 shares of Preferred Stock, par value $.10 per share.

                The Board of Directors is hereby empowered to cause the
        Preferred Stock to be issued from time to time for such consideration as
        it may from time to time fix, and to cause such Preferred Stock to be
        issued in series with such voting powers and such designations,
        preferences and relative, participating, optional or other special
        rights as designated by the Board of Directors in the resolution
        providing for the issue of such series. Shares of Preferred Stock of any
        one series shall be identical in all respects.

                5. The corporation is to have perpetual existence.

                6. In furtherance and not in limitation of the powers conferred
        by statute, the board of directors is expressly authorized to make,
        alter or repeal the bylaws of the corporation.

                7. The directors of the corporation shall be divided into three
        classes, as nearly equal in number as reasonably possible, with the
        directors in each class



                                       2
<PAGE>   3
        to hold office until their successors are elected and qualified. At each
        annual meeting of stockholders of the corporation, the successors to the
        class of directors whose term shall then expire shall be elected to hold
        office for a three-year term. If the number of directors is changed, any
        increase or decrease shall be apportioned among the classes so as to
        maintain the number of directors in each class as nearly equal as
        possible, and any additional directors of any class elected to fill a
        vacancy resulting from an increase in such class shall hold office for a
        term that shall coincide with the remaining term of that class, but in
        no case will a decrease in the number of directors shorten the term of
        any incumbent director. A director shall hold office until the annual
        meeting for the year in which his or her term expires and until his or
        her successor shall be elected and shall qualify, subject, however, to
        prior death, resignation, retirement, disqualification or removal from
        office.

                Notwithstanding the foregoing, no person shall be elected or
        serve as a director if such person is in a management position with or a
        director of a direct competitor of the Company.

                Notwithstanding the foregoing, whenever the holders of any one
        or more classes or series of Preferred Stock issued by the corporation
        shall have the right, voting separately by class or series, to elect
        directors at an annual or special meeting of stockholders, the election,
        term of office, filling of vacancies and other features of such
        directorships shall be governed by the terms of this Certificate of
        Incorporation or the resolution or resolutions adopted by the Board of
        Directors pursuant to Paragraph 4 hereof, and such directors so elected
        shall not be divided into classes pursuant to this Paragraph 7 unless
        expressly provided by such terms.

                Meetings of stockholders may be held within or without the State
        of Delaware, as the bylaws may provide. The books of the corporation may
        be kept (subject to any provision contained in the statutes) outside the
        State of Delaware at such place or places as may be designated from time
        to time by the board of directors or in the bylaws of the corporation.

                Elections of directors need not be by written ballot unless the
        bylaws of the corporation shall so provide.

                8. Subject to the rights, if any, of the holders of shares of
        Preferred Stock then outstanding, any or all of the directors of the
        corporation may be removed from office by the stockholders at any annual
        or special meeting of stockholders of the corporation, the notice of
        which shall state that the removal of a director or directors is among
        the purposes of the meeting, but only for cause, by the affirmative vote
        of at least 66-2/3% of the outstanding shares of Common Stock of the
        corporation.



                                       3
<PAGE>   4
                9. Newly created directorships resulting from any increase in
        the number of directors or any vacancy on the Board of Directors
        resulting from death, resignation, disqualification, removal or other
        cause shall be filled solely by the affirmative vote of a majority of
        the remaining directors then in office, even though less than a quorum,
        or by a sole remaining director. Any director elected in accordance with
        the preceding sentence shall hold office for the remainder of the full
        term of the class of directors in which the new directorship was created
        or the vacancy occurred and until such director's successor shall have
        been elected and qualified. No decrease in the number of directors
        constituting the Board of Directors shall shorten the term of any
        incumbent director.

                10. The corporation reserves the right to amend, alter, change
        or repeal any provision contained in this certificate of incorporation,
        in the manner now or hereafter prescribed by statute, and all rights
        conferred upon stockholders herein are granted subject to this
        reservation.

                11. Any action required or permitted to be taken at any annual
        or special meeting of stockholders may be taken only upon the vote of
        the stockholders at an annual or special meeting duly called and may not
        be taken by written consent of the stockholders.

                12. Special meetings of the stockholders of the corporation for
        any purpose or purposes may be called at any time by the Board of
        Directors, the Chairman of the Board of Directors or the President of
        the corporation. Special meetings of the stockholders of the corporation
        may not be called by any other person or persons.

                13. A director of the corporation shall not be personally liable
        to the corporation or its stockholders for monetary damages for breach
        of fiduciary duty as a director, except for liability (i) for any breach
        of the director's duty of loyalty to the corporation or its
        stockholders, (ii) for acts or omissions not in good faith or which
        involve intentional misconduct or a knowing violation of law, (iii)
        under Section 174 of the Delaware General Corporation Law, or (iv) for
        any transaction from which the director derived an improper personal
        benefit.

                14. (a) Each person who was or is made a party or is threatened
        to be made a party to or is involved in any action, suit or proceeding,
        whether civil, criminal, administrative or investigative (hereinafter a
        "proceeding"), by reason of the fact that he or she, or a person of whom
        he or she is the legal representative, is or was a director or officer
        of the corporation or is or was serving at the request of the
        corporation as a director, officer, employee or agent of another
        corporation or of a partnership, joint venture, trust or other
        enterprise, including service with respect to employee benefit plans,
        whether the basis of such proceeding is alleged action in an official
        capacity as a director, officer, employee or agent or in any other
        capacity



                                       4
<PAGE>   5

        while serving as a director, officer, employee or agent, shall be
        indemnified and held harmless by the corporation to the fullest extent
        authorized by the Delaware General Corporation Law, as the same exists
        or may hereafter be amended (but, in the case of any such amendment,
        only to the extent that such amendment permits the corporation to
        provide broader indemnification rights than said law permitted the
        corporation to provide prior to such amendment), against all expense,
        liability and loss (including attorneys' fees, judgments, fines, ERISA
        excise taxes or penalties and amounts paid or to be paid in settlement)
        reasonably incurred or suffered by such person in connection therewith
        and such indemnification shall continue as to a person who has ceased to
        be a director, officer, employee or agent and shall inure to the benefit
        of his or her heirs, executors and administrators; provided, however,
        that, except as provided in subparagraph (b) hereof, the corporation
        shall indemnify any such person seeking indemnification in connection
        with a proceeding (or part thereof) initiated by such person only if
        such proceeding (or part thereof) was authorized by the board of
        directors of the corporation. The right to indemnification conferred in
        this Paragraph 14 shall be a contract right and shall include the right
        to be paid by the corporation the expenses incurred in defending any
        such proceeding in advance of its final disposition; provided, however,
        that, if the Delaware General Corporation Law requires, the payment of
        such expenses incurred by a director or officer in his or her capacity
        as a director or officer (and not in any other capacity in which service
        was or is rendered by such person while a director or officer,
        including, without limitation, service to an employee benefit plan) in
        advance of the final disposition of a proceeding, shall be made upon
        delivery to the corporation of an undertaking, by or on behalf of such
        director or officer, to repay all amounts so advanced if it shall
        ultimately be determined that such director or officer is not entitled
        to be indemnified under this Paragraph 14 or otherwise. The corporation
        may, by action of its board of directors, provide indemnification to
        employees and agents of the corporation with the same scope and effect
        as the foregoing indemnification of directors and officers.

                    (b) If a claim under subparagraph (a) of this Paragraph 14
        is not paid in full by the corporation within thirty days after a
        written claim has been received by the corporation, the claimant may at
        any time thereafter bring suit against the corporation to recover the
        unpaid amount of the claim and, if successful in whole or in part, the
        claimant shall be entitled to be paid also the expense of prosecuting
        such claim. It shall be a defense to any such action (other than an
        action brought to enforce a claim for expenses incurred in defending any
        proceeding in advance of its final disposition where the required
        undertaking, if any is required, has been tendered to the corporation)
        that the claimant has not met the standards of conduct which make it
        permissible under the Delaware General Corporation Law for the
        corporation to indemnify the claimant for the amount claimed, but the
        burden of proving such defense shall be on the corporation. Neither the
        failure of the corporation (including its board of directors,
        independent



                                       5
<PAGE>   6

        legal counsel, or its stockholders) to have made a determination prior
        to the commencement of such action that indemnification of the claimant
        is proper in the circumstances because he or she has met the applicable
        standard of conduct set forth in the Delaware General Corporation Law,
        nor an actual determination by the corporation (including its board of
        directors, independent legal counsel, or its stockholders) that the
        claimant has not met such applicable standard of conduct, shall be a
        defense to the action or create a presumption that the claimant has not
        met the applicable standard of conduct.

                    (c) The right to indemnification and the payment of expenses
        incurred in defending a proceeding in advance of its final disposition
        conferred in this Paragraph 14 shall not be exclusive of any other right
        which any person may have or hereafter acquire under any statute,
        provision of the certificate of incorporation, bylaw, agreement, vote of
        stockholders or disinterested directors or otherwise.

                    (d) The corporation may maintain insurance, at its expense,
        to protect itself and any director, officer, employee or agent of the
        corporation or another corporation, partnership, joint venture, trust or
        other enterprise against any such expense, liability or loss, whether or
        not the corporation would have the power to indemnify such person
        against such expense, liability or loss under the Delaware General
        Corporation Law.

                15. At an annual meeting of stockholders, only such business
        shall be conducted, and only such proposals shall be acted upon, as
        shall have been brought before the annual meeting (a) by, or at the
        direction of, a majority of the directors, or (b) by any stockholder of
        the corporation who complies with the notice procedures set forth in
        this Paragraph 15. For a proposal to be properly brought before an
        annual meeting by a stockholder, the stockholder must have given timely
        notice thereof in writing to the Secretary of the corporation. To be
        timely, a stockholder's notice must be delivered to, or mailed and
        received at, the principal executive offices of the corporation not less
        than 60 days prior to the scheduled annual meeting, regardless of any
        postponements, deferrals or adjournments of that meeting to a later
        date; provided, however, that if less than 70 days' notice or prior
        public disclosure of the date of the scheduled annual meeting is given
        or made, notice by the stockholder, to be timely, must be so delivered
        or received not later than the close of business on the tenth day
        following the earlier of the day on which such notice of the date of the
        scheduled annual meeting was mailed or the day on which such public
        disclosure was made. A stockholder's notice to the Secretary shall set
        forth as to each matter the stockholder proposes to bring before the
        annual meeting (a) a brief description of the proposal desired to be
        brought before the annual meeting and the reasons for conducting such
        business at the annual meeting, (b) the name and address, as they appear
        on the corporation's books, of the stockholder proposing such business
        and any other stockholders



                                       6
<PAGE>   7

        known by such stockholder to be supporting such proposal, (c) the class
        and number of shares of the corporation's stock which are beneficially
        owned by the stockholder on the date of such stockholder notice and by
        any other stockholders known by such stockholder to be supporting such
        proposal on the date of such stockholder notice, and (d) any financial
        interest of the stockholder in such proposal.

                The presiding officer of the annual meeting shall determine and
        declare at the annual meeting whether the stockholder proposal was made
        in accordance with the terms of this Paragraph 15. If the presiding
        officer determines that a stockholder proposal was not made in
        accordance with the terms of this Paragraph 15, he or she shall so
        declare at the annual meeting and any such proposal shall not be acted
        upon at the annual meeting.

                This provision shall not prevent the consideration and approval
        or disapproval at the annual meeting of reports of officers, directors
        and committees of the Board of Directors, but, in connection with such
        reports, no new business shall be acted upon at such annual meeting
        unless stated, filed and received as herein provided.

                16. Subject to the rights, if any, of the holders of shares of
        Preferred Stock then outstanding only persons who are nominated in
        accordance with the following procedures shall be eligible for election
        as directors. Nominations of persons for election to the Board of
        Directors of the corporation may be made at a meeting of stockholders by
        or at the direction of the Board of Directors by any nominating
        committee or person appointed by the Board or by any stockholder of the
        corporation entitled to vote for the election of directors at the
        meeting who complies with the notice procedures set forth in this
        Paragraph 16. Such nominations, other than those made by or at the
        direction of the Board, shall be made pursuant to timely notice in
        writing to the Secretary of the corporation. To be timely, a
        stockholder's notice must be delivered to, or mailed and received at,
        the principal executive offices of the corporation not less than 60 days
        prior to the scheduled annual meeting, regardless of any postponements,
        deferrals or adjournments of that meeting to a later date; provided,
        however, that if less than 70 days' notice or prior public disclosure of
        the date of the scheduled annual meeting is given or made, notice by the
        stockholder, to be timely, must be so delivered or received not later
        than the close of business on the tenth day following the earlier of the
        day on which such notice of the date of the scheduled annual meeting was
        mailed or the day on which such public disclosure was made. A
        stockholder's notice to the Secretary shall set forth (a) as to each
        person whom the stockholder proposes to nominate for election or
        reelection as a director, (i) the name, age, business address and
        residence address of the person, (ii) the principal occupation or
        employment of the person, (iii) the class and number of shares of
        capital stock of the corporation which are beneficially owned by the



                                       7
<PAGE>   8

        person and (iv) any other information relating to the person that is
        required to be disclosed in solicitations for proxies for election of
        directors pursuant to Rule 14a under the Securities Exchange Act of
        1934, as amended; and (b) as to the stockholder giving the notice (i)
        the name and address, as they appear on the corporation's books, of the
        stockholder and (ii) the class and number of shares of the corporation's
        stock which are beneficially owned by the stockholder on the date of
        such stockholder notice. The corporation may require any proposed
        nominee to furnish such other information as may reasonably be required
        by the corporation to determine the eligibility of such proposed nominee
        to serve as director of the corporation.

                The presiding officer of the annual meeting shall determine and
        declare at the annual meeting whether the nomination was made in
        accordance with the terms of this Paragraph 16. If the presiding officer
        determines that a nomination was not made in accordance with the terms
        of this Paragraph 16, he or she shall so declare at the annual meeting
        and any such defective nomination shall be disregarded.

                17. Notwithstanding anything contained in this Certificate of
        Incorporation to the contrary, the affirmative vote of at least 66-2/3%
        of the outstanding shares of Common Stock of the corporation shall be
        required to amend or repeal Paragraphs 7, 8, 9, 11, 12 or 17 of this
        Certificate of Incorporation or to adopt any provision inconsistent
        therewith.

        6. This Fifth Restated Certificate of Incorporation was duly adopted by
a vote of stockholders at the annual meeting of stockholders held April 7, 2000
in accordance with the provisions of Sections 242 and 245 of the Delaware
General Corporation Law.

        IN WITNESS WHEREOF, BECKMAN COULTER, INC. has caused this Fifth Restated
Certificate of Incorporation to be signed by John P. Wareham, its Chief
Executive Officer, and attested by William H. May, its Secretary, dated April

SECTION 102.   COMPLIANCE CERTIFICATES AND OPINIONS.

        Upon any application or request by the Corporation to the Trustee to
take any action under any provision of this Indenture, the Corporation shall
furnish to the Trustee such certificates and opinions as may be required under

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

               (1) a statement that each individual signing such certificate or
        opinion has read such covenant or condition and the definitions herein
        relating thereto;

SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Corporation stating that the

Corporation, unless such counsel knows, or in the exercise of reasonable care

<PAGE>   13

        Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

        Whenever, subsequent to the receipt by the Trustee of any Board
Resolution, Officer's Certificate, Opinion of Counsel or other document or
instrument, a clerical, typographical or other inadvertent or unintentional
error or omission shall be discovered therein, a new document or instrument may
be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates of
the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is
substituted. Anything in this Indenture to the contrary notwithstanding, if any
such corrective document or instrument indicates that action has been taken by
or at the request of the Corporation which could not have been taken had the
original document or instrument not contained such error or omission, the action
so taken shall not be invalidated or otherwise rendered ineffective but shall be
and remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith. Without limiting the generality of
the foregoing, any Securities issued under the authority of such defective
document or instrument shall nevertheless be the valid obligations of the
Corporation entitled to the benefits of this Indenture equally and ratably with
all other Outstanding Securities, except as aforesaid.

SECTION 104.   ACTS OF HOLDERS; RECORD DATES.

        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 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 Corporation.
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 601) conclusive in favor of the Trustee and
the Corporation, if made in the manner provided in this Section.

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

                                       8
<PAGE>   14


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

        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 Corporation
in reliance thereon, whether or not notation of such action is made upon such
Security.

        The Corporation may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series 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 of such series; provided that the
Corporation 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 any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take or revoke 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 of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Corporation 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 of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Corporation, 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 of the relevant series 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 of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction or to revoke
the same, 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 of such series 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


                                       9
<PAGE>   15

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 of the relevant series on the date
such action is taken. Promptly after any record date is set pursuant to this
paragraph, the Trustee, at the Corporation's expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date
to be sent to the Corporation in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106.

        With respect to any record date set pursuant to this Section, the party
hereto which sets such record date 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 of the relevant series 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.

SECTION 105. NOTICES, ETC., TO TRUSTEE AND CORPORATION.

        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 Corporation shall be
        sufficient for every purpose hereunder if made, given, furnished or
        filed in writing (which may be made via facsimile) to or with a
        Responsible Officer of the Trustee at its Corporate Trust Office, or

               (2) the Corporation 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 Corporation addressed to it at the address of its
        principal office specified in the first paragraph of this instrument,
        Attention: Treasurer, or at any other address previously furnished in
        writing to the Trustee by the Corporation.

SECTION 106. NOTICE TO HOLDERS; WAIVER.

                                       10
<PAGE>   16

        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 which is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to
apply to this 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 Corporation shall
bind its 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.

SECTION 111. BENEFITS OF INDENTURE.

        Unless otherwise specified pursuant to Section 301 with respect to the
Securities of any series, nothing in this Indenture or in the Securities,
express or implied, shall give to any Person, other than the parties hereto,
their successors hereunder and the Holders, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

SECTION 112. GOVERNING LAW.

        This Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York, without regard to conflicts
of laws principles thereof.

SECTION 113. LEGAL HOLIDAYS.

        Unless otherwise specified pursuant to Section 301 with respect to the
Securities of any series, 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 Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) 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, unless that Business Day is in a different calendar
year, in which case the payment will be made on the preceding Business Day, in
each case, with the same force and effect as if made on the Interest Payment
Date or Redemption Date, or at the Stated Maturity.

SECTION 114. NO SECURITY INTEREST CREATED.

        Nothing in this Indenture or in the Securities expressed or implied,
shall be construed to constitute a security interest under the Uniform
Commercial Code or similar legislation, as now or hereafter enacted and in
effect in any jurisdiction where property of the Corporation or its subsidiaries
is located.

all Securities of such series, to waive compliance by the Corporation with
certain provisions of the Indenture. 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 therefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

Holder of this Security shall not have the right to institute any proceeding

Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

exchange, but the Corporation may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

shall be certified by the Secretary or an Assistant Secretary of the Corporation
and delivered to the Trustee at or prior to the delivery of the Officer's

        With respect to Securities of a series offered in a Periodic Offering,
the Board Resolution (or action taken pursuant thereto), Officer's Certificate
or supplemental indenture referred to above may provide general terms or
parameters for Securities of such series and provide either that the specific
terms of particular Securities of such series shall be specified in a Company
Order or that such terms shall be determined by the Corporation in accordance
with other procedures specified in a Company Order as contemplated by the third
paragraph of Section 303.

        Notwithstanding Section 301(2) herein and unless otherwise expressly
provided with respect to a series of Securities, the aggregate principal amount
of a series of Securities may be increased and additional Securities of such
series may be issued up to the maximum aggregate principal amount authorized

SECTION 302.   DENOMINATIONS.

        The Securities of each series shall be issuable only in fully registered
form without coupons and only in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination
with respect to the Securities of any series, the Securities of such series
shall be issuable 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 Corporation by its
Chairman of the Board, its Chief Executive Officer, its President, a Vice
President or the Treasurer, and attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile.

        Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Corporation shall bind the
Corporation, notwithstanding that such

                                       22
<PAGE>   28

individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Securities or did not hold such offices at
the date of such Securities.

        At any time and from time to time after the execution and delivery of
this Indenture, the Corporation may deliver Securities of any series executed by
the Corporation to the Trustee for authentication, together with a Company Order
for the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities, provided, however, that in the case of Securities offered in a
Periodic Offering, the Trustee shall authenticate and deliver such Securities
from time to time in accordance with such other procedures (including, without
limitation, the receipt by the Trustee of oral or electronic instructions from
the Corporation or its duly authorized agents, promptly confirmed in writing)
acceptable to the Trustee as may be specified by or pursuant to a Company Order
delivered to the Trustee prior to the time of the first authentication of
Securities of such series. If the form or terms of the Securities of the series
have been established by or pursuant to one or more Board Resolutions as
permitted by Sections 201 and 301, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee shall be provided with, and (subject to Section
601) shall be fully protected in relying upon, an Opinion of Counsel stating,

               (1) if the form of such Securities has been established by or
        pursuant to Board Resolution as permitted by Section 201, that such form
        has been established in conformity with the provisions of this
        Indenture;

               (2) if the terms of such Securities have been, or in the case of
        Securities of a series offered in a Periodic Offering, will be,
        established by or pursuant to Board Resolution as permitted by Section
        301, that such terms have been, or in the case of Securities of a series
        offered in a Periodic Offering, will be, established in conformity with
        the provisions of this Indenture, subject, in the case of Securities of
        a series offered in a Periodic Offering, to any conditions specified in
        such Opinion of Counsel; and

               (3) that such Securities, when issued and executed by the
        Corporation and when authenticated and delivered by the Trustee in the
        manner and subject to any conditions specified in such Opinion of
        Counsel, will constitute valid and legally binding obligations of the
        Corporation enforceable in accordance with their terms, subject to
        bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
        and similar laws of general applicability relating to or affecting
        creditors' rights and to general equity principles.

        If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

        Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to

                                       23
<PAGE>   29

deliver the Officer's Certificate otherwise required pursuant to Section 301 or
the Company Order and Opinion of Counsel otherwise required pursuant to such
preceding paragraph at or prior to the authentication of each Security of such
series if such documents are delivered at or prior to the authentication upon
original issuance of the first Security of such series to be issued.

        With respect to Securities of a series offered in a Periodic Offering,
the Trustee may rely, as to the authorization by the Corporation of any of such
Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

        Each Security shall be dated the date of its authentication.

        No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature of an authorized officer, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the
Corporation, and the Corporation shall deliver such Security to the Trustee for
cancellation as provided in Section 309, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 304. TEMPORARY SECURITIES.

        Pending the preparation of definitive Securities of any series, the
Corporation may execute, and upon Company Order the Trustee shall authenticate
and deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any 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 of any series are issued, the Corporation will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Corporation in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series, the Corporation shall execute and
the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

SECTION 305.   REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

        The Corporation shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office or in any other
office or agency of the Corporation in a Place of Payment being herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Corporation 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.

        Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Corporation in a Place of Payment for that
series, the Corporation shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount.

        At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and 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 Corporation shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

        All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Corporation, evidencing the
same debt, and entitled to the same benefits under this Indenture, as the
Securities 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 Corporation or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Corporation 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 Corporation 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, 906 or 1106 not involving any transfer.

        If the Securities of any series (or of any series and specified tenor)
are to be redeemed, the Corporation shall not be required (A) to issue, register
the transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption and ending at the close of business on
the day of such

                                       25
<PAGE>   31

mailing, or (B) 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.

        The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

               (1) Each Global Security authenticated under this Indenture shall
        be registered in the name of the Depositary designated for such Global
        Security or a nominee thereof and delivered to such Depositary or a
        nominee thereof or custodian therefor, and each such Global Security
        shall constitute a single Security for all purposes of this Indenture.

               (2) Notwithstanding any other provision in this Indenture, no
        Global Security may be exchanged in whole or in part for Securities
        registered, and no transfer of a Global Security in whole or in part may
        be registered, in the name of any Person other than the Depositary for
        such Global Security or a nominee thereof unless (A) such Depositary has
        notified the Corporation that it is unwilling or unable to continue as
        Depositary for such Global Security and a successor Depositary has not
        been appointed by the Corporation within 90 days of receipt by the
        Corporation of such notification, (B) if at any time the Depositary
        ceases to be a clearing agency registered under the Exchange Act at a
        time when the Depositary is required to be so registered to act as such
        Depositary and no successor Depositary shall have been appointed by the
        Corporation within 90 days after it became aware of such cessation, or
        (C) there shall exist such circumstances, if any, in addition to or in
        lieu of the foregoing as have been specified for this purpose as
        contemplated by Section 301. Notwithstanding the foregoing, the
        Corporation may at any time in its sole discretion determine that
        Securities issued in the form of a Global Security shall no longer be
        represented in whole or in part by such Global Security, and the
        Trustee, upon receipt of a Company Order therefor, shall authenticate
        and deliver definitive Securities in exchange in whole or in part for
        such Global Security.

               (3) Subject to Clause (2) above, any exchange or transfer of a
        Global Security for other Securities may be made in whole or in part,
        and all Securities issued in exchange for or upon transfer of a Global
        Security or any portion thereof shall be registered in such names as the
        Depositary for such Global Security shall direct.

               (4) Every Security authenticated and delivered upon registration
        of transfer of, or in exchange for or in lieu of, a Global Security or
        any portion thereof, whether pursuant to this Section, Section 304, 306,
        906 or 1106 or otherwise, shall be authenticated and delivered in the
        form of, and shall be, a Global Security, unless such Security is
        registered in the name of a Person other than the Depositary for such
        Global Security or a nominee thereof.

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

                                       26
<PAGE>   32

        If any mutilated Security is surrendered to the Trustee, the Corporation
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

        If there shall be delivered to the Corporation 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 Corporation or the Trustee that such Security has been acquired by a bona
fide purchaser, the Corporation shall execute and the Trustee shall authenticate
and deliver, in lieu of any such destroyed, lost or stolen Security, a new
Security of the same series and of like tenor and principal amount 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 Corporation in its discretion
may, instead of issuing a new Security, pay such Security.

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

        Every new Security of any series issued pursuant to this Section in lieu
of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Corporation, 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 of that series 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.

        Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, 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.

        Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, any interest on any Security of any series 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 Corporation, at
its election in each case, as provided in Clause (1) or (2) below:

                                       27
<PAGE>   33

               (1) The Corporation may elect to make payment of any Defaulted
        Interest to the Persons in whose names the Securities of such series (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 Corporation
        shall notify the Trustee in writing of the amount of Defaulted Interest
        proposed to be paid on each Security of such series and the date of the
        proposed payment, and at the same time the Corporation shall deposit
        with the Trustee an amount of money equal to the aggregate amount
        proposed to be paid in respect of such Defaulted Interest or shall make
        arrangements satisfactory to the Trustee for such deposit prior to the
        date of the proposed payment, such money when deposited to be held in
        trust for the benefit of the Persons entitled to such Defaulted Interest
        as in this Clause provided. Thereupon the Trustee shall fix a Special
        Record Date for the payment of such Defaulted Interest which shall be
        not more than 15 days and not less than 10 days prior to the date of the
        proposed payment and not less than 10 days after the receipt by the
        Trustee of the notice of the proposed payment. The Trustee shall
        promptly notify the Corporation of such Special Record Date and, in the
        name and at the expense of the Corporation, shall cause notice of the
        proposed payment of such Defaulted Interest and the Special Record Date
        therefor to be given to each Holder of Securities of such series in the
        manner set forth in Section 106, 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 of such series (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 Corporation may make payment of any Defaulted Interest on
        the Securities of any series in any other lawful manner not inconsistent
        with the requirements of any securities exchange, if any, on which such
        Securities may be listed, and upon such notice as may be required by
        such exchange, if, after notice given by the Corporation 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.

SECTION 308. PERSONS DEEMED OWNERS.

        Prior to due presentment of a Security for registration of transfer, the
Corporation, the Trustee and any agent of the Corporation 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 any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the


                                       28
<PAGE>   34

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

        None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership interest
of a Global Security or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.

        Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any Agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depositary, as a Holder, with respect to
such Global Security or impair, as between such depositary and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depositary as Holder of
such Global Security.

SECTION 309. CANCELLATION.

        All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Corporation may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Corporation may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Corporation has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of in its customary manner or
as directed by a Company Order; provided, however, that the Trustee shall not be
required to destroy such canceled Securities.

SECTION 310. COMPUTATION OF INTEREST.

        Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 311. CUSIP NUMBERS.

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

                                       29
<PAGE>   35

numbers. The Corporation shall promptly notify the Trustee of any change in the
CUSIP numbers with respect to the Securities.

                                   ARTICLE IV.
                           SATISFACTION AND DISCHARGE

SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE.

        This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Corporation, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

               (1)    either

                      (A) all Securities theretofore authenticated and delivered
               (other than (i) Securities which have been destroyed, lost or
               stolen and which have been replaced or paid as provided in
               Section 306 and (ii) Securities for whose payment money has
               theretofore been deposited in trust or segregated and held in
               trust by the Corporation and thereafter repaid to the Corporation
               or discharged from such trust, as provided in Section 1003) have
               been delivered to the Trustee for cancellation; or

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

                                (i) have become due and payable, or

                                (ii) will become due and payable at their Stated
                        Maturity within one year, or

                                (iii) are to be called for redemption within one
                        year under arrangements satisfactory to the Trustee for
                        the giving of notice of redemption by the Trustee in the
                        name, and at the expense, of the Corporation,

               and the Corporation, in the case of (i), (ii) or (iii) above, has
               deposited or caused to be deposited with the Trustee as trust
               funds in trust for the purpose (i) money in an amount, (ii)
               Government Obligations (as defined in Section 1304) which through
               the scheduled payment of principal and interest in respect
               thereof in accordance with their terms will provide, not later
               than the due date of any payment, money in an amount, or (iii) a
               combination thereof, sufficient, in the case of (ii) or (iii), in
               the opinion of a nationally recognized firm of independent public
               accountants expressed in a written certification thereof
               delivered to the Trustee, to pay and discharge, and which shall
               be applied by the Trustee to pay


                                       30
<PAGE>   36

                and discharge, the entire indebtedness on such Securities not
                theretofore delivered to the Trustee for cancellation, for
                principal and any premium and interest to the date of such
                deposit (in the case of Securities which have become due and
                payable) or to the Stated Maturity or Redemption Date, as the
                case may be;

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

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

        Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Corporation to the Trustee under Section 607, the obligations
of the Corporation to any Authenticating Agent under Section 614 and, if money
shall have been deposited with the Trustee pursuant to subclause (B) of Clause
(1) of this Section, the obligations of the Trustee under Section 402 and the
last paragraph of Section 1003 shall survive such satisfaction and discharge.

SECTION 402. APPLICATION OF TRUST MONEY.

        Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Corporation acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                   ARTICLE V.
                                    REMEDIES

SECTION 501. EVENTS OF DEFAULT.

        "Event of Default," wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless it is inapplicable to a particular series or is specifically deleted or
modified in the Board Resolution (or action taken pursuant thereto), Officer's
Certificate or supplemental indenture under which such series of Securities is
issued or has been deleted or modified in an indenture supplemental hereto:

              (1) default in the payment of any interest upon any Security of
       that series when it becomes due and payable, and continuance of such
       default for a period of 30 days; provided, however, that if the
       Corporation is permitted by the terms of the


                                       31
<PAGE>   37

       Securities of such series to defer the payment in question, the date on
       which such payment is due and payable shall be the date on which the
       Corporation is required to make payment following such deferral, if such
       deferral has been elected pursuant to the terms of the Securities; or

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

              (3) default in the making of any sinking fund payment, when and as
       due by the terms of a Security of that series, and continuance of such
       default for a period of 60 days; or

              (4) default in the performance, or breach, of any covenant of the
       Corporation in this Indenture (other than a covenant a default in whose
       performance or whose breach is elsewhere in this Section specifically
       dealt with or which has expressly been included in this Indenture solely
       for the benefit of series of Securities other than that series), and
       continuance of such default or breach for a period of 90 days after there
       has been given, by registered or certified mail, to the Corporation by
       the Trustee or to the Corporation and the Trustee by the Holders of at
       least 25% in principal amount of the Outstanding Securities of that
       series a written notice specifying such default or breach and requiring
       it to be remedied and stating that such notice is a "Notice of Default"
       hereunder, unless the Trustee, or the Trustee and the Holders of a
       principal amount of Securities of such series not less than the principal
       amount of Securities the Holders of which gave such notice, as the case
       may be, shall agree in writing to an extension of such period prior to
       its expiration; provided, however, that the Trustee, or the Trustee and
       the Holders of such principal amount of Securities of such series, as the
       case may be, shall be deemed to have agreed to an extension of such
       period if corrective action is initiated by the Corporation within such
       period and is being diligently pursued; or

              (5) the entry by a court having jurisdiction in the premises of
       (A) a decree or order for relief in respect of the Corporation in an
       involuntary case or proceeding under any applicable federal or state
       bankruptcy, insolvency, reorganization or other similar law or (B) a
       decree or order adjudging the Corporation a bankrupt or insolvent, or
       approving as properly filed a petition seeking reorganization,
       arrangement, adjustment or composition of or in respect of the
       Corporation under any applicable federal or state law, or appointing a
       custodian, receiver, liquidator, assignee, trustee, sequestrator or other
       similar official of the Corporation or of any substantial part of its
       property, or ordering the winding-up or liquidation of its affairs, and
       the continuance of any such decree or order for relief or any such other
       decree or order unstayed and in effect for a period of 90 consecutive
       days; or

              (6) the commencement by the Corporation of a voluntary case or
       proceeding under any applicable federal or state bankruptcy, insolvency,
       reorganization or other similar law or of any other case or proceeding to
       be adjudicated a bankrupt or insolvent,


                                       32

       or the consent by it to the entry of a decree or order for relief in
       respect of the Corporation in an involuntary case or proceeding under any
       applicable federal or state bankruptcy, insolvency, reorganization or
       other similar law or to the commencement of any bankruptcy or insolvency
       case or proceeding against it, or the filing by it of a petition or
       answer or consent seeking reorganization or relief under any applicable
       federal or state law, or the consent by it to the filing of such petition
       or to the appointment of or taking possession by a custodian, receiver,
       liquidator, assignee, trustee, sequestrator or other similar official of
       the Corporation or of any substantial part of its property, or the making
       by it of an assignment for the benefit of creditors, or the admission by
       it in writing of its inability to pay its debts generally as they become
       due, or the authorization of any such action by the Board of Directors;
       or

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

SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

       If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount of all the Securities
of that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Corporation (and to the Trustee if given by Holders), and upon
any such declaration such principal amount (or specified amount) shall become
immediately due and payable.

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

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

                     (A) all overdue interest on all Securities of that series,

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

                     (C) to the extent that payment of such interest is lawful,
              interest upon overdue interest at the rate or rates prescribed
              therefor in such Securities, and

                                       33
<PAGE>   39
                      (D) all sums paid or advanced by the Trustee hereunder and
               the reasonable compensation, expenses, disbursements and advances
               of the Trustee, its agents and counsel;

        and

               (2) all Events of Default with respect to Securities of that
        series, other than the non-payment of the principal of Securities of
        that series which have become due solely by such declaration of
        acceleration, have been cured or waived as provided in Section 513.

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

SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

        The Corporation covenants that if

               (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 Corporation will, upon demand of the Trustee, 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 any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

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

        If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement

                                       34
<PAGE>   40

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 504. TRUSTEE MAY FILE PROOFS OF CLAIM.

        In case of any judicial proceeding relative to the Corporation (or any
other obligor upon the Securities), its property or its 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 607.

        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 a creditors'
or other similar committee.

SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

        All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of 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 506. APPLICATION OF MONEY COLLECTED.

        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 any premium
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 607;

                                       35
<PAGE>   41

               Second: To the payment of the amounts then due and unpaid for
        principal of and any premium and interest on the Securities in respect
        of which or for the benefit of which such money has been collected,
        ratably, without preference or priority of any kind, according to the
        amounts due and payable on such Securities for principal and any premium
        and interest, respectively; and

               Third: To the payment of the balance, if any, to the Corporation.

SECTION 507. LIMITATION ON SUITS.

        No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless

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

               (2) the Holders of not less than 25% in principal amount of the
        Outstanding Securities of all affected series, considered as one class,
        or, in the case of an Event of Default of the character specified above
        in Section 501(1), (2) or (3), that series, shall have made written
        request to the Trustee to institute proceedings in respect of such Event
        of Default in its own name as Trustee hereunder;

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

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

               (5) no direction inconsistent with such written request has been
        given to the Trustee during such 60-day period by the Holders of a
        majority in principal amount of the Outstanding Securities of all
        affected series, considered as one class, or, in the case of an Event of
        Default of the character specified above in Section 501(1), (2) or (3),
        that series,

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

SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
             INTEREST.

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


                                       36
<PAGE>   42

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

SECTION 509. RESTORATION OF RIGHTS AND REMEDIES.

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

section 510. 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 511. DELAY OR OMISSION NOT WAIVER.

        No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.

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

SECTION 512. CONTROL BY HOLDERS.

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

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

                                       37
<PAGE>   43

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

               (3) subject to the provisions of Section 601, the Trustee shall
        have the right to decline to follow any such direction if the Trustee in
        good faith shall, by a Responsible Officer or Officers of the Trustee,
        determine that the proceeding so directed would involve the Trustee in
        personal liability.

        If an Event of Default is continuing with respect to all Outstanding
Securities, the Holders of a majority in principal amount of all the Outstanding
Securities, considered as one class, shall have the right to make such
direction, and not the Holders of Securities of any one series.

SECTION 513. WAIVER OF PAST DEFAULTS.

        The Holders of not less than a majority in principal amount of the
Outstanding Securities of all series with respect to which any default under the
Indenture shall have occurred and be continuing (voting as one class) may, on
behalf of the Holders of all Securities of all such series, waive such past
default under the Indenture and its consequences, except a default

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

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

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

SECTION 514. 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, including legal fees and expenses 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 (i) any suit
instituted by the Trustee, (ii) any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or (iii) any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest on any Security on or after the


                                       38
<PAGE>   44

respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

SECTION 515. WAIVER OF STAY OR EXTENSION LAWS.

        The Corporation covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any 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 Corporation (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any such
law and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE VI.

SECTION 601. CERTAIN DUTIES AND RESPONSIBILITIES.

        The duties and responsibilities of the Trustee shall be as provided in
this Indenture and no duties shall be inferred or implied against the Trustee.
Notwithstanding the foregoing, no provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder or in the exercise
of any of its rights or powers. 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 602. NOTICE OF DEFAULTS.

        If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(4) with respect to Securities of such series, no 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, an Event of Default with respect
to Securities of such series.

SECTION 603. CERTAIN RIGHTS OF TRUSTEE.

        Subject to the provisions of Section 601:

                (1) the Trustee may conclusively rely and shall be fully
        protected in acting or refraining from acting upon any resolution,

               (3) whenever in the administration of this Indenture the Trustee
        shall deem it desirable that a matter be proved or established prior to
        taking, suffering or omitting any action hereunder, the Trustee (unless
        other evidence be herein specifically prescribed) may, in the absence of
        bad faith on its part, rely upon an Officer's Certificate;

               (4) the Trustee may consult with counsel of its selection and the
        advice of such counsel or any Opinion of Counsel with respect to legal
        matters shall be full and complete authorization and protection in

        Holders shall have offered to the Trustee reasonable security or
        indemnity satisfactory to it against the costs, expenses and liabilities
        which might be incurred by it in compliance with such request or
        direction;

               (6) the Trustee shall not be bound to make any investigation into

        document, but the Trustee, in its discretion, may make such further
        inquiry or investigation into such facts or matters as it may see fit,
        and, if the Trustee shall determine to make such further inquiry or
        investigation, it shall be entitled, at reasonable times previously
        notified to the Corporation, to examine the relevant books, records and
        premises of the Corporation, personally or by agent or attorney at the
        sole cost of the Corporation and shall incur no liability or additional
        liability of any kind by reason of such inquiry or investigation;

        or negligence on the part of any agent or attorney appointed with due
        care by it hereunder;

<PAGE>   46


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

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

SECTION 604. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

        The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Corporation, and neither the Trustee nor any Authenticating Agent assumes
any responsibility for their correctness. The Trustee makes no representations
as to the validity or sufficiency of this Indenture or of the Securities.
Neither the Trustee nor any Authenticating Agent shall be accountable for the
use or application by the Corporation of Securities or the proceeds thereof.

SECTION 605. MAY HOLD SECURITIES.

        The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Corporation, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Corporation with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 606. MONEY HELD IN TRUST.

        Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise

SECTION 607. COMPENSATION AND REIMBURSEMENT.

        The Corporation agrees:

               (1) to pay to the Trustee from time to time such compensation as
        shall be agreed to in writing between the Corporation and the Trustee
        for all services rendered by it hereunder (which compensation shall not
        be limited by any provision of law in regard to the compensation of a
        trustee of an express trust);

               (2) except as otherwise expressly provided herein, to reimburse
        the Trustee upon its request for all expenses, disbursements and

<PAGE>   47

        Trustee in accordance with any provision of this Indenture (including
        the reasonable compensation and the expenses and disbursements of its
        agents and counsel), except any such expense, disbursement or advance as
        may be attributable to its negligence, willful misconduct or bad faith;

        or bad faith on its part, arising out of or in connection with the
        acceptance or administration of the trust or trusts hereunder, including
        the costs and expenses of defending itself against any claim whether
        asserted by the Corporation, a Holder or any other Person or liability
        in connection with the exercise or performance of any of its powers or
        duties hereunder.

        The Trustee shall have a lien prior to the Securities upon all property
and funds held by it hereunder for any amount owing it or any predecessor
Trustee pursuant to this Section 607, except with respect to funds held in trust
for the benefit of the Holders of particular Securities.

        Without limiting any rights available to the Trustee under applicable
law, when the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

        The provisions of this Section shall survive the termination of this
Indenture.

SECTION 608. CONFLICTING INTERESTS.

        If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.

SECTION 609. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

        There shall at all times be a Trustee hereunder with respect to the
Securities of each series, which may be Trustee hereunder for Securities of one
or more other series. Each Trustee shall be a Person that is eligible pursuant
to the Trust Indenture Act to act as such and has a combined capital and surplus
of at least $50,000,000. If any such Person publishes reports of condition at
least annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section and to the extent
permitted by the Trust Indenture Act, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the


                                       42
<PAGE>   48

Trustee with respect to the Securities of any series shall cease to be eligible
in accordance with the provisions of this Section, it shall resign immediately
in the manner and with the effect hereinafter specified in this Article.

SECTION 610. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

        No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

        The Trustee may resign at any time with respect to the Securities of one
or more series by giving written notice thereof to the Corporation. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition, at the expense of the
Corporation, any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Securities of such series.

        The Trustee may be removed at any time with respect to the Securities of
any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Corporation. Upon such removal, the Corporation may petition, at its expense,
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

        If at any time:

               (1) the Trustee shall fail to comply with Section 608 after
        written request therefor by the Corporation or by any Holder who has
        been a bona fide Holder of a Security for at least six months, or

               (2) the Trustee shall cease to be eligible under Section 609 and
        shall fail to resign after written request therefor by the Corporation
        or by any such Holder, or

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

then, in any such case, (A) the Corporation by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

        If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more

                                       43
<PAGE>   49

series, the Corporation, by a Board Resolution, shall promptly appoint a
successor Trustee or Trustees with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed
with respect to the Securities of one or more or all of such series and that at
any time there shall be only one Trustee with respect to the Securities of any
particular series) and shall comply with the applicable requirements of Section
611. If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee with respect to the Securities
of any series shall be appointed by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series delivered to the
Corporation and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the
applicable requirements of Section 611, become the successor Trustee with
respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Corporation. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the
Corporation or the Holders and accepted appointment in the manner required by
Section 611, any Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

        The Corporation shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series to all
Holders of Securities of such series in the manner provided in Section 106. Each
notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

SECTION 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

        In case of the appointment hereunder of a successor Trustee with respect
to all Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Corporation and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Corporation 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.

        In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Corporation, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor


                                       44
<PAGE>   50


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

        Upon request of any such successor Trustee, the Corporation shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in the first or second preceding paragraph, as the case may be.

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

SECTION 612. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

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

SECTION 613. PREFERENTIAL COLLECTION OF CLAIMS AGAINST CORPORATION.

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

                                       45
<PAGE>   51

SECTION 614. APPOINTMENT OF AUTHENTICATING AGENT.

        The Trustee may appoint an Authenticating Agent or Agents acceptable to
the Corporation with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Corporation and shall at all times be a corporation organized
and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by federal or state
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

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

        An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Corporation. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Corporation. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Corporation and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No

                                       46
<PAGE>   52

successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

        The Corporation agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

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

        This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

SECTION 615. TRUSTEE'S APPLICATION FOR INSTRUCTIONS FROM THE CORPORATION.

        Any application by the Trustee for written instructions from the
Corporation may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date
on and/or after which such action shall be taken or such omission shall be
effective. The Trustee shall not be liable to the Corporation for any action
taken by, or omission of, the Trustee in accordance with a proposal included in
such application on or after the date specified in such application (which date
shall not be less than five Business Days after the date any officer of the
Corporation actually receives such application, unless any such officer shall
have consented in writing to any earlier date) unless prior to taking any such
action (or the effective date in the case of an omission), the Trustee shall
have received written instructions in response to such application specifying
the action to be taken or omitted.

        as the Trustee may reasonably require, of the names and addresses of the
        Holders of Securities of each series as of such Regular Record Date, and

        within 30 days after the receipt by the Corporation of any such request,
        a list of similar form and content as of a date not more than 15 days
        prior to the time such list is furnished;

excluding from any such list names and addresses received by the Trustee in its
capacity as Security Registrar.

SECTION 702. PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

        The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

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

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

SECTION 703. REPORTS BY TRUSTEE.

        The Trustee shall transmit to Holders such reports concerning the
Trustee and its actions under this Indenture as may be required pursuant to the
Trust Indenture Act at the times and in the manner provided pursuant thereto. If
required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within
60 days after each May 15 following the date of this Indenture, deliver to
Holders a brief report, dated as of such May 15, which complies with the
provisions of such Section 313(a).

        A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee, with each stock exchange upon which any
Securities are listed, with the Commission and with the Corporation. The
Corporation will promptly notify the Trustee when any Securities are listed on
any stock exchange or any delisting thereof.

SECTION 704. REPORTS BY CORPORATION.

transmit to Holders, such information, documents and other reports, and such
summaries thereof, as may be required pursuant to the Trust Indenture Act at the
times and in the manner provided pursuant to such Act; provided that any such
information, documents or reports required to be filed with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the
Trustee within 15 days after the same is so required to be filed with the
Commission. Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Corporation's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officer's Certificates).

                                  ARTICLE VIII.
                  CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER

SECTION 801. CORPORATION MAY CONSOLIDATE, ETC., ONLY ON CERTAIN TERMS.

        The Corporation shall not consolidate with or merge into any other
Person or convey, transfer or lease its properties and assets substantially as
an entirety to any Person, and no Person shall consolidate with or merge into
the Corporation or convey, transfer or lease its properties and assets
substantially as an entirety to the Corporation, unless:

               (1) in case the Corporation shall consolidate with or merge into
        another Person or convey, transfer or lease its properties and assets
        substantially as an entirety to any Person, the Person formed by such
        consolidation or into which the Corporation is merged or the Person
        which acquires by conveyance or transfer, or which leases, the
        properties and assets of the Corporation substantially as an entirety
        shall be a corporation, partnership, limited liability company or trust
        organized and existing under the laws of the United States of America or
        any State thereof or the District of Columbia and shall expressly
        assume, by an indenture supplemental hereto, executed and delivered to
        the Trustee, in form satisfactory to the Trustee, the due and punctual
        payment of the principal of (and premium, if any) and interest on all
        the Securities and the performance of every covenant of this Indenture
        on the part of the Corporation to be performed or observed;

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

               (3) such other conditions as may be specified pursuant to Section

        satisfied; and

               (4) the Corporation shall deliver to the Trustee an Officer's
        Certificate and an Opinion of Counsel, each stating that such
        consolidation, merger, conveyance or transfer and, if a supplemental
        indenture is required in connection with such transaction, such
        supplemental indenture comply with this Article and that all conditions
        precedent herein


                                       49
<PAGE>   55

        provided for relating to such transaction have been complied with; and
        the Trustee, subject to Section 601, may rely upon such Officer's
        Certificate and Opinion of Counsel as conclusive evidence that such
        transaction complies with this Section 801.

SECTION 802. SUCCESSOR SUBSTITUTED.

        Upon any consolidation of the Corporation with, or merger of the
Corporation into, any other Person or any conveyance or transfer of the
properties and assets of the Corporation as an entirety or substantially as an
entirety in accordance with Section 801, the successor Person formed by such
consolidation or into which the Corporation is merged or to which such
conveyance or transfer is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Corporation under this Indenture with the
same effect as if such successor Person had been named as the Corporation
herein, and thereafter the predecessor Person shall be relieved of all
obligations and covenants under this Indenture and the Securities.

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

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

                                   ARTICLE IX.
                             SUPPLEMENTAL INDENTURES

SECTION 901. SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.

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

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

<PAGE>   56

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

               (3) to add any additional Events of Default for the benefit of
        the Holders of all or any series of Securities (and if such additional
        Events of Default are to be for the benefit of less than all series of
        Securities, stating that such additional Events of Default are expressly
        being included solely for the benefit of such series); or

               (4) to add to or change any of the provisions of this Indenture
        to such extent as shall be necessary to permit or facilitate the
        issuance of Securities in bearer form, registrable or not registrable as
        to principal, and with or without interest coupons, or to facilitate the
        issuance of Securities in uncertificated form; or

               (5) to add to, change or eliminate any of the provisions of this
        Indenture in respect of one or more series of Securities; provided that
        any such addition, change or elimination (A) shall neither (i) apply to
        any Security of any series created prior to the execution of such
        supplemental indenture and entitled to the benefit of such provision nor
        (ii) modify the rights of the Holder of any such Security with respect
        to such provision or (B) shall become effective only when there is no
        such Security Outstanding; or

               (6) to secure the Securities; or

               (7) to establish the form or terms of Securities of any series
        as permitted by Sections 201 and 301; or

               (8) to evidence and provide for the acceptance of appointment
        hereunder by a successor Trustee with respect to the Securities of one
        or more series and to add to or change any of the provisions of this
        Indenture as shall be necessary to provide for or facilitate the
        administration of the trusts hereunder by more than one Trustee,
        pursuant to the requirements of Section 611; or

               (9) to cure any ambiguity, to correct or supplement any provision
        herein which may be defective or inconsistent with any other provision
        herein, or to make any other provisions with respect to matters or
        questions arising under this Indenture; provided that such action
        pursuant to this Clause (9) shall not adversely affect the interests of
        the Holders of Securities of any series in any material respect.

SECTION 902. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

        With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of all series affected by such supplemental
indenture (voting as one class), by Act of said Holders delivered to the
Corporation and the Trustee, the Corporation, when


                                       51
<PAGE>   57

authorized by a Board Resolution, and the Trustee may enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture, or modifying in any manner the rights of the
Holders of Securities under this Indenture; provided, however, that no such
supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby,

               (1) change the Stated Maturity of the principal of, or any
        installment of principal of or interest on, any Security (other than
        pursuant to the terms of such Security), or reduce the principal amount
        thereof or the rate of interest thereon or any premium payable upon the
        redemption thereof, or reduce the amount of the principal of an Original
        Issue Discount Security or any other Security which would be due and
        payable upon a declaration of acceleration of the Maturity thereof
        pursuant to Section 502 or change the coin or currency in which any
        Security or any premium or interest thereon is payable, or impair the
        right to institute suit for the enforcement of any such payment on or
        after the Stated Maturity thereof (or, in the case of redemption, on or
        after the Redemption Date), or

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

               (3) modify any of the provisions of this Section, Section 513 or
        Section 1006, except to increase any such percentage or to provide that
        certain other provisions of this Indenture cannot be modified or waived
        without the consent of the Holder of each Outstanding Security affected
        thereby; provided, however, that this clause shall not be deemed to
        require the consent of any Holder with respect to changes in the
        references to "the Trustee" and concomitant changes in this Section and
        Section 1006, or the deletion of this proviso, in accordance with the
        requirements of Sections 611 and 901(8).

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

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

SECTION 903. EXECUTION OF SUPPLEMENTAL INDENTURES.

                                       52
<PAGE>   58

        In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

SECTION 904. EFFECT OF SUPPLEMENTAL INDENTURES.

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

SECTION 905. CONFORMITY WITH TRUST INDENTURE ACT.

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

SECTION 906. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

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

                                   ARTICLE X.
                                   COVENANTS

SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

        The Corporation covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY.

        The Corporation will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Corporation in respect of the Securities of that series


                                       53
<PAGE>   59

and this Indenture may be served. The Corporation will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Corporation shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Corporation hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

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

SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

        If the Corporation shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and 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 Corporation shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium or interest on any Securities of that series, 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 Corporation will promptly notify the Trustee of its action or
failure so to act.

        The Corporation will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (1) hold all sums
held by it for the payment of the principal of (and premium, if any) or interest
on Securities in trust for the benefit of the Persons entitled thereto until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, (2) give the Trustee notice of any default by the Corporation (or any
other obligor upon the Securities) in the making of any payment of principal
(and premium, if any) or interest, (3) comply with the provisions of the Trust
Indenture Act applicable to it as a Paying Agent and (4) during the continuance
of any default by the Corporation (or any other obligor upon the Securities of
that series) in the making of any payment in respect of the Securities of that
series, upon the written request of the Trustee, forthwith pay to the Trustee
all sums held in trust by such Paying Agent for payment in respect of the
Securities of that series.

                                       54
<PAGE>   60

        The Corporation may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust hereunder by the Corporation 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
Corporation 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 Corporation, in trust for the payment of the principal of or any premium
or interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Corporation on Company Request, or (if then held by the Corporation)
shall be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look only to the Corporation for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Corporation 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 Corporation 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, 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
Corporation.

SECTION 1004. CORPORATE EXISTENCE.

        Subject to Article Eight, the Corporation will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises.

SECTION 1005. STATEMENT BY OFFICERS AS TO DEFAULT.

        The Corporation will deliver to the Trustee, on or before October 15 of
each calendar year or on or before such other day in each calendar year as the
Corporation and the Trustee may from time to time agree upon, an Officer's
Certificate, stating whether or not to the best knowledge of the signers thereof
the Corporation 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 Corporation
shall be in default, specifying all such defaults and the nature and status
thereof of which they may have knowledge.

        The Corporation shall deliver to the Trustee, as soon as possible and in
any event within five days after the Corporation becomes aware of the occurrence
of any Event of Default or an event which, with notice or the lapse of time or
both, would constitute an Event of Default, an Officers' Certificate setting
forth the details of such Event of Default or default and the action which the
Corporation proposes to take with respect thereto.

<PAGE>   61

SECTION 1006. WAIVER OF CERTAIN COVENANTS.

        Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Corporation may, with respect to the Securities
of any series, omit in any particular instance to comply with any term,
provision or condition set forth in any covenant provided pursuant to Section
301(19), 901(2) or 901(7) for the benefit of the Holders of such series if
before the time for such compliance the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series shall, by Act of
such Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Corporation and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.

                                   ARTICLE XI.
                            REDEMPTION OF SECURITIES

SECTION 1101. APPLICABILITY OF ARTICLE.

        Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

        The election of the Corporation to redeem any Securities shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities. In case of any redemption at the election of
the Corporation, the Corporation shall, at least 45 days prior to the Redemption
Date fixed by the Corporation (unless a shorter notice shall be satisfactory to
the Trustee), notify the Trustee of such Redemption Date, of the principal
amount of Securities of such series to be redeemed and, if applicable, of the
tenor of the Securities to be redeemed. In the case of any redemption of
Securities (A) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, or (B)
pursuant to an election of the Corporation which is subject to a condition
specified in the terms of such Securities or elsewhere in this Indenture, the
Corporation shall furnish the Trustee with an Officer's Certificate evidencing
compliance with such restriction or condition.

SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

        If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate


                                       56
<PAGE>   62

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

        The Trustee shall promptly notify the Corporation in writing of the
Securities selected for redemption as aforesaid and, in the case of any
Securities selected for partial redemption as aforesaid, the principal amount
thereof to be redeemed.

        The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

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

SECTION 1104. NOTICE OF REDEMPTION.

        Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

        All notices of redemption shall identify the Securities to be redeemed
(including CUSIP number(s)) and shall state:

                      (1) the Redemption Date;

                      (2) the Redemption Price;

                      (3) if less than all the Outstanding Securities of any
               series and of a specified tenor consisting of more than a single
               Security are to be redeemed, the identification (and, in the case
               of partial redemption of any such Securities, the principal
               amounts) of the particular Securities to be redeemed and, if less
               than all the Outstanding Securities of any series and of a
               specified tenor consisting of a single Security are to be
               redeemed, the principal amount of the particular Security to be
               redeemed;

                                       57
<PAGE>   63

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

                      (5) the place or places where each such Security is to be
               surrendered for payment of the Redemption Price and accrued
               interest, if any, unless it shall have been specified as
               contemplated by Section 301 with respect to such Securities that
               such surrender shall not be required;

                      (6) that the redemption is for a sinking fund, if such
               is the case; and

                      (7) such other matters as the Corporation shall deem
               desirable or appropriate.

        Unless otherwise specified with respect to any Securities in accordance
with Section 301, with respect to any redemption of Securities at the election
of the Corporation, unless, upon the giving of notice of such redemption,
Defeasance shall have been effected with respect to such Securities pursuant to
Section 1302, such notice may state that such redemption shall be conditional
upon the receipt by the Trustee or the Paying Agent(s) for such Securities, on
or prior to the date fixed for such redemption, of money sufficient to pay the
principal of and any premium and interest on such Securities and that if such
money shall not have been so received such notice shall be of no force or effect
and the Corporation shall not be required to redeem such Securities. In the
event that such notice of redemption contains such a condition and such money is
not so received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Trustee or Paying Agent(s) for the
Securities otherwise to have been redeemed shall promptly return to the Holders
thereof any of such Securities which had been surrendered for payment upon such
redemption.

        Notice of redemption of Securities to be redeemed at the election of the
Corporation, and any notice of non-satisfaction of redemption as aforesaid,
shall be given by the Corporation or, at the Corporation's request, by the
Trustee in the name and at the expense of the Corporation. Subject to the
preceding paragraph, any such notice of redemption shall be irrevocable.

SECTION 1105. DEPOSIT OF REDEMPTION PRICE.

        On or prior to the Redemption Date specified in the notice of redemption
given as provided in Section 1104, the Corporation will deposit with the Trustee
or with one or more Paying Agents (or if the Corporation is acting as its own
Paying Agent, the Corporation will segregate and hold in trust as provided in
Section 1003) an amount of money sufficient to pay the Redemption Price of; and
any accrued interest on, all the Securities which are to be redeemed on that
date.

                                       58
<PAGE>   64

SECTION 1106. SECURITIES PAYABLE ON REDEMPTION DATE.

        Notice of redemption having been given as aforesaid, and the conditions,
if any, set forth in such notice having been satisfied, the Securities or
portions thereof 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, in the case of an unconditional notice of redemption, the Corporation
shall default in the payment of the Redemption Price and accrued interest, if
any) such Securities or portions thereof, if interest-bearing, shall cease to
bear interest. Upon surrender of any such Security for redemption in accordance
with said notice, such Security or portion thereof shall be paid by the
Corporation at the Redemption Price, together with accrued interest, if any, to
the Redemption Date; provided, however, that no such surrender shall be a
condition to such payment if so specified as contemplated by Section 301 with
respect to such Security, and provided further that, unless otherwise specified
as contemplated by Section 301, installments of interest whose Stated Maturity
is on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

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

SECTION 1107. SECURITIES REDEEMED IN PART.

        Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Corporation or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Corporation and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Corporation shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities of the same series
and of like tenor, 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 XII.
                                 SINKING FUNDS

SECTION 1201. APPLICABILITY OF ARTICLE.

        The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

        The minimum amount of any sinking fund payment provided for by the terms
of any Securities is herein referred to as a "mandatory sinking fund payment,"
and any payment in excess of such minimum amount provided for by the terms of
such Securities is herein referred to


                                       59
<PAGE>   65

as an "optional sinking fund payment." If provided for by the terms of any
Securities, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities as provided for by the terms of such
Securities.

SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

        The Corporation (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Corporation pursuant to the terms of such Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

        Not less than 45 days prior to each sinking fund payment date for any
Securities, the Corporation will deliver to the Trustee an Officer's Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and stating the basis for such credit and that such Securities have
not been previously so credited and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 days prior to each such sinking
fund payment date, the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Corporation in the manner provided in Section 1104. Such notice having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1105 and 1106.

                                  ARTICLE XIII.
                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301. APPLICABILITY OF ARTICLE.

        Unless, pursuant to Section 301, provision is made that either or both
of (A) defeasance of any Securities or any series of Securities under Section
1302 and (B) covenant defeasance of any Securities or any series of Securities
under Section 1303 shall not apply to such Securities of a series, then the
provisions of either or both of Sections 1302 and Section 1303, as the case may
be, together with Sections 1304 and 1305, shall be applicable to the Outstanding
Securities of such series upon compliance with the conditions set forth below in
this Article.

SECTION 1302. DEFEASANCE AND DISCHARGE.

        The Corporation may cause itself to be discharged from its obligations
with respect to any Securities or any series of Securities on and after the date
the conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Corporation
shall be deemed to have paid and discharged the entire indebtedness represented
by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Corporation, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder: (1) the rights of Holders of such
Securities to receive, solely from the trust fund described in Section 1304 and
as more fully set forth in such Section, payments in respect of the principal of
and any premium and interest on such Securities when payments are due, (2) the
Corporation's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003 and with respect to the Trustee under Section 607, (3)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(4) this Article. Subject to compliance with this Article, Defeasance with
respect to any Securities or any series of Securities by the Corporation is
permitted under this Section 1302 notwithstanding the prior exercise by the
Corporation of its rights under Section 1303 with respect to such Securities.
Following a Defeasance, payment of such Securities may not be accelerated
because of an Event of Default.

SECTION 1303. COVENANT DEFEASANCE.

        The Corporation may cause itself to be released from its obligations
under any covenants provided pursuant to Section 301(19), 901(2), 901(6) or
901(7) with respect to any Securities or any series of Securities for the
benefit of the Holders of such Securities and the occurrence of any event
specified in Sections 501(4) (with respect to any such covenants provided
pursuant to Section 301(19), 901(2), 901(6) or 901(7)) or 501(7) shall be deemed
not to be or result in an Event of Default with respect to such Securities as
provided in this Section, in each case on and after the date the conditions set
forth in Section 1304 are satisfied (hereinafter called "Covenant Defeasance").
For this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Corporation may omit to comply with and shall have no liability
in respect of any term, condition or limitation set forth in any such specified
Section (to the extent so specified in the case of Section 501(4)), whether
directly or indirectly by reason of any reference elsewhere herein to any such
Section or by reason of any reference in any such Section to any other provision
herein or in any other document, but the remainder of this Indenture and such
Securities shall be unaffected thereby.

SECTION 1304. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

        The following shall be the conditions to the application of Section 1302
or Section 1303 to any Securities or any series of Securities, as the case may
be:

                (1) The Corporation shall irrevocably have deposited or caused
        to be deposited with the Trustee as trust funds in trust for the purpose
        of making the following


                                       61
<PAGE>   67

        payments, specifically pledged as security for, and dedicated solely to,
        the benefit of the Holders of such Securities, (A) money in an amount,
        or (B) Government Obligations which through the scheduled payment of
        principal and interest in respect thereof in accordance with their terms
        will provide, not later than the due date of any payment, money in an
        amount, or (C) a combination thereof, sufficient, in the case of (B) or
        (C), in the opinion of a nationally recognized firm of independent
        public accountants expressed in a written certification thereof
        delivered to the Trustee, to pay and discharge, and which shall be
        applied by the Trustee to pay and discharge, the principal of and any
        premium and interest on such Securities on the respective Stated
        Maturities or on any Redemption Date established pursuant to Clause (3)
        below, in accordance with the terms of this Indenture and such
        Securities. As used herein, "Government Obligation" means (x) any
        security which is (i) a direct obligation of the United States of
        America or the government which issued the foreign currency in which
        such Securities are payable, for the payment of which its full faith and
        credit is pledged or (ii) an obligation of a Person controlled or
        supervised by and acting as an agency or instrumentality of the United
        States of America or such government which issued the foreign currency
        in which such Securities are payable, the payment of which is
        unconditionally guaranteed as a full faith and credit obligation by the
        United States of America or such other government, which, in either case
        (i) or (ii), is not callable or redeemable at the option of the issuer
        thereof, and (y) any depositary receipt issued by a bank (as defined in
        Section 3(a)(2) of the Securities Act) as custodian with respect to any
        Government Obligation which is specified in clause (x) above and held by
        such bank for the account of the holder of such depositary receipt, or
        with respect to any specific payment of principal of or interest on any
        Government Obligation which is so specified and held, provided that
        (except as required by law) such custodian is not authorized to make any
        deduction from the amount payable to the holder of such depositary
        receipt from any amount received by the custodian in respect of the
        Government Obligation or the specific payment of principal or interest
        evidenced by such depositary receipt.

                (2) No event which is, or after notice or lapse of time or both
        would become, an Event of Default with respect to such Securities or any
        other Securities shall have occurred and be continuing at the time of
        such deposit or, with regard to any such event specified in Sections
        501(5) and (6), at any time on or prior to the 90th day after the date
        of such deposit (it being understood that this condition shall not be
        deemed satisfied until after such 90th day).

                (3) If the Securities are to be redeemed prior to Stated
        Maturity (other than from mandatory sinking fund payments or analogous
        payments), notice of such redemption shall have been duly given pursuant
        to this Indenture or provision therefor satisfactory to the Trustee
        shall have been made.

                (4) The Corporation shall have delivered to the Trustee an
        Officer's Certificate and an Opinion of Counsel, each stating that all
        conditions precedent with respect to such Defeasance or Covenant
        Defeasance have been complied with.

SECTION 1305. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST;
              MISCELLANEOUS PROVISIONS.

        Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (including the proceeds thereof) deposited with
the Trustee pursuant to Section 1304 in respect of any Securities shall be held
in trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Corporation acting as its own Paying Agent) as
the Trustee may determine, to the Holders of such Securities, of all sums due
and to become due thereon in respect of principal and any premium and interest,
but money so held in trust need not be segregated from other funds except to the
extent required by law.

        The Corporation shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

        Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Corporation from time to time upon Company Request
any money or Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

                                  ARTICLE XIV.
                           IMMUNITY OF INCORPORATORS,
                      STOCKHOLDERS, OFFICERS AND DIRECTORS

SECTION 1401. INDENTURE AND SECURITIES SOLELY CORPORATE OBLIGATIONS.

        No recourse for the payment of the principal of or any premium or
interest on any Security, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Corporation in this Indenture or in any supplemental indenture, or in any
Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer or director, as
such, past, present or future, of the Corporation or of any successor
corporation, either directly or through the Corporation or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issue of the Securities.

        This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

or give an opinion as to such matters in one or several documents.

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 such Officer's 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 Corporation stating that the
information with respect to such factual matters is in the possession of the
Corporation, 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.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         Whenever, subsequent to the receipt by the Trustee of any Board
Resolution, Officer's Certificate, Opinion of Counsel or other document or
instrument, a clerical, typographical or other inadvertent or unintentional
error or omission shall be discovered therein, a new document or instrument may
be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates of
the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is
substituted. Anything in this Indenture to the contrary notwithstanding, if any
such corrective document or instrument indicates that action has been taken by
or at the request of the Corporation which could not have been taken had the
original document or instrument not contained such error or omission, the action
so taken shall not be invalidated or otherwise rendered ineffective but shall be
and remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith. Without limiting the generality of
the foregoing, any Securities issued under the authority of such defective
document or instrument shall nevertheless be the valid obligations of the
Corporation entitled to the benefits of this Indenture equally and ratably with
all other Outstanding Securities, except as aforesaid.

SECTION 104. ACTS OF HOLDERS; RECORD DATES.



                                       8
<PAGE>   15


         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 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 Corporation.
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 601) conclusive in favor of the Trustee and
the Corporation, if made in the manner provided in this Section.

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

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

         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 Corporation
in reliance thereon, whether or not notation of such action is made upon such
Security.

         The Corporation may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series 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 of such series; provided that the
Corporation 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 any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take or revoke 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 of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Corporation 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



                                       9
<PAGE>   16


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 of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the
Corporation, 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 of the relevant series 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 of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction or to revoke
the same, 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 of such series 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 of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Corporation's expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be sent to the
Corporation in writing and to each Holder of Securities of the relevant series
in the manner set forth in Section 106.

         With respect to any record date set pursuant to this Section, the party
hereto which sets such record date 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 of the relevant series 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



                                       10
<PAGE>   17


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.

SECTION 105. NOTICES, ETC., TO TRUSTEE AND CORPORATION.

         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 Corporation shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing (which may be made via facsimile) to or with the
         Trustee at its Corporate Trust Office, Attention: Corporate Trust
         Administration, or

                  (2) the Corporation 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 Corporation addressed to it at the address of its
         principal office specified in the first paragraph of this instrument,
         Attention: Treasurer, or at any other address previously furnished in
         writing to the Trustee by the Corporation.

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 which is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any



                                       11
<PAGE>   18


provision of the Trust Indenture Act which 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 Corporation shall
bind its 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.

SECTION 111. BENEFITS OF INDENTURE.

         Unless otherwise specified pursuant to Section 301 with respect to the
Securities of any series, nothing in this Indenture or in the Securities,
express or implied, shall give to any Person, other than the parties hereto,
their successors hereunder and the Holders, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

SECTION 112. GOVERNING LAW.

         This Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York, without regard to conflicts
of laws principles thereof.

SECTION 113. LEGAL HOLIDAYS.

         Unless otherwise specified pursuant to Section 301 with respect to the
Securities of any series, 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 Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) 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, unless that Business Day is in a different calendar
year, in which case the payment will be made on the preceding Business Day, in
each case, with the same force and effect as if made on the Interest Payment
Date or Redemption Date, or at the Stated Maturity.

SECTION 114. NO SECURITY INTEREST CREATED.

         Nothing in this Indenture or in the Securities expressed or implied,

is located.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Corporation and the rights of the Holders of the Securities of all series
affected under the Indenture at any time by the Corporation and the Trustee with
the consent of the Holders of a majority in principal amount of the Securities
of all series at the time Outstanding affected thereby (voting as one class).
The Indenture contains provisions permitting the Holders of not less than a
majority in principal amount of the Securities of all series at the time
Outstanding with respect to which a default under the Indenture shall have
occurred and be continuing (voting as one class), on behalf of the Holders of
the Securities of all such series, to waive, with certain exceptions, such past
default with respect to all such series and its consequences. The Indenture also
permits the Holders of not less than a majority in principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Corporation with
certain provisions of the Indenture. 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 therefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Corporation,
which is absolute and unconditional, to pay the principal of and any premium 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 Corporation in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Corporation 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 this series and of like tenor, of authorized



                                       18

denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

         The Securities of this series 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 of this series are exchangeable for a like aggregate principal
amount of Securities of this series and of like tenor 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 Corporation 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 Corporation, the Trustee and any agent of the Corporation 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
Corporation, the Trustee nor any such agent shall be affected by notice to the
contrary.

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

         The Indenture and the Securities issued thereby shall be governed by
and construed in accordance with the laws of the State of New York.

         thereof;

                  (18) any addition, modification or deletion of any Events of
         Default or covenants provided with respect to any Securities of the
         series and any change in the right of the Trustee or the requisite

                                       22
<PAGE>   29


         All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and (subject to Section 303) set
forth, or determined in the manner provided, in the Officer's Certificate
referred to above or in any such indenture supplemental hereto.

         If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Corporation
and delivered to the Trustee at or prior to the delivery of the Officer's
Certificate setting forth the terms or the manner of determining the terms of
the series.

         With respect to Securities of a series offered in a Periodic Offering,
the Board Resolution (or action taken pursuant thereto), Officer's Certificate
or supplemental indenture referred to above may provide general terms or
parameters for Securities of such series and provide either that the specific
terms of particular Securities of such series shall be specified in a Company
Order or that such terms shall be determined by the Corporation in accordance
with other procedures specified in a Company Order as contemplated by the third
paragraph of Section 303.

         Notwithstanding Section 301(2) herein and unless otherwise expressly
provided with respect to a series of Securities, the aggregate principal amount
of a series of Securities may be increased and additional Securities of such
series may be issued up to the maximum aggregate principal amount authorized
with respect to such series as increased.

SECTION 302. DENOMINATIONS.

         The Securities of each series shall be issuable only in fully
registered form without coupons and only in such denominations as shall be
specified as contemplated by Section 301. In the absence of any such specified
denomination with respect to the Securities of any series, the Securities of
such series shall be issuable 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 Corporation by its
Chairman of the Board, its Chief Executive Officer, its President, a Vice
President or the Treasurer and attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be
manual or facsimile.

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

         At any time and from time to time after the execution and delivery of
this Indenture, the Corporation may deliver Securities of any series executed by
the Corporation to the Trustee for



                                       23
<PAGE>   30


authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities, provided, however, that in
the case of Securities offered in a Periodic Offering, the Trustee shall
authenticate and deliver such Securities from time to time in accordance with
such other procedures (including, without limitation, the receipt by the Trustee
of oral or electronic instructions from the Corporation or its duly authorized
agents, promptly confirmed in writing) acceptable to the Trustee as may be
specified by or pursuant to a Company Order delivered to the Trustee prior to
the time of the first authentication of Securities of such series. If the form
or terms of the Securities of the series have been established by or pursuant to
one or more Board Resolutions as permitted by Sections 201 and 301, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, an Opinion of Counsel stating,

                  (1) if the form of such Securities has been established by or
         pursuant to Board Resolution as permitted by Section 201, that such
         form has been established in conformity with the provisions of this
         Indenture;

                  (2) if the terms of such Securities have been, or in the case
         of Securities of a series offered in a Periodic Offering, will be,
         established by or pursuant to Board Resolution as permitted by Section
         301, that such terms have been, or in the case of Securities of a
         series offered in a Periodic Offering, will be, established in
         conformity with the provisions of this Indenture, subject, in the case
         of Securities of a series offered in a Periodic Offering, to any
         conditions specified in such Opinion of Counsel; and

                  (3) that such Securities, when issued and executed by the
         Corporation and when authenticated and delivered by the Trustee in the
         manner and subject to any conditions specified in such Opinion of
         Counsel, will constitute valid and legally binding obligations of the
         Corporation enforceable in accordance with their terms, subject to
         bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
         and similar laws of general applicability relating to or affecting
         creditors' rights and to general equity principles.

         If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officer's Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.



                                       24
<PAGE>   31


         With respect to Securities of a series offered in a Periodic Offering,
the Trustee may rely, as to the authorization by the Corporation of any of such
Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature of an authorized officer, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the
Corporation, and the Corporation shall deliver such Security to the Trustee for
cancellation as provided in Section 309, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 304. TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Corporation may execute, and upon Company Order the Trustee shall authenticate
and deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any 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 of any series are issued, the Corporation will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Corporation in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series, the Corporation shall execute and
the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Corporation shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office or in any other
office or agency of the Corporation



                                       25
<PAGE>   32


in a Place of Payment being herein sometimes referred to as the "Security
Register") in which, subject to such reasonable regulations as it may prescribe,
the Corporation 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.

         Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Corporation in a Place of Payment for that
series, the Corporation shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and 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 Corporation shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Corporation, evidencing the
same debt, and entitled to the same benefits under this Indenture, as the
Securities 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 Corporation or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Corporation 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 Corporation 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, 906 or 1106 not involving any transfer.

         If the Securities of any series (or of any series and specified tenor)
are to be redeemed, the Corporation shall not be required (A) to issue, register
the transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption and ending at the close of business on
the day of such mailing, or (B) 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.

         The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:




                                       26
<PAGE>   33

                  (1) Each Global Security authenticated under this Indenture
         shall be registered in the name of the Depositary designated for such
         Global Security or a nominee thereof and delivered to such Depositary
         or a nominee thereof or custodian therefor, and each such Global
         Security shall constitute a single Security for all purposes of this
         Indenture.

                  (2) Notwithstanding any other provision in this Indenture, no
         Global Security may be exchanged in whole or in part for Securities
         registered, and no transfer of a Global Security in whole or in part
         may be registered, in the name of any Person other than the Depositary
         for such Global Security or a nominee thereof unless (A) such
         Depositary has notified the Corporation that it is unwilling or unable
         to continue as Depositary for such Global Security and a successor
         Depositary has not been appointed by the Corporation within 90 days of
         receipt by the Corporation of such notification, (B) if at any time the
         Depositary ceases to be a clearing agency registered under the Exchange
         Act at a time when the Depositary is required to be so registered to
         act as such Depositary and no successor Depositary shall have been
         appointed by the Corporation within 90 days after it became aware of
         such cessation, or (C) there shall exist such circumstances, if any, in
         addition to or in lieu of the foregoing as have been specified for this
         purpose as contemplated by Section 301. Notwithstanding the foregoing,
         the Corporation may at any time in its sole discretion determine that
         Securities issued in the form of a Global Security shall no longer be
         represented in whole or in part by such Global Security, and the
         Trustee, upon receipt of a Company Order therefor, shall authenticate
         and deliver definitive Securities in exchange in whole or in part for
         such Global Security.

                  (3) Subject to Clause (2) above, any exchange or transfer of a
         Global Security for other Securities may be made in whole or in part,
         and all Securities issued in exchange for or upon transfer of a Global
         Security or any portion thereof shall be registered in such names as
         the Depositary for such Global Security shall direct.

                  (4) Every Security authenticated and delivered upon
         registration of transfer of, or in exchange for or in lieu of, a Global
         Security or any portion thereof, whether pursuant to this Section,
         Section 304, 306, 906 or 1106 or otherwise, shall be authenticated and
         delivered in the form of, and shall be, a Global Security, unless such
         Security is registered in the name of a Person other than the
         Depositary for such Global Security or a nominee thereof.

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

         If any mutilated Security is surrendered to the Trustee, the
Corporation shall execute and the Trustee shall authenticate and deliver in
exchange therefor a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Corporation 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


                                       27
<PAGE>   34

the absence of notice to the Corporation or the Trustee that such Security has
been acquired by a bona fide purchaser, the Corporation shall execute and the
Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or
stolen Security, a new Security of the same series and of like tenor and
principal amount 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 Corporation in its discretion
may, instead of issuing a new Security, pay such Security.

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

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Corporation, 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 of that series 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.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, 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.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, any interest on any Security of any series
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
Corporation, at its election in each case, as provided in Clause (1) or (2)
below:

                  (1) The Corporation may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series
         (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
         Corporation shall notify the Trustee in writing of the amount of
         Defaulted Interest proposed to be paid on each Security of such series
         and the date of the proposed payment,


                                       28
<PAGE>   35
         and at the same time the Corporation shall deposit with the Trustee an
         amount of money equal to the aggregate amount proposed to be paid in
         respect of such Defaulted Interest or shall make arrangements
         satisfactory to the Trustee for such deposit prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons entitled to such Defaulted Interest as in this
         Clause provided. Thereupon the Trustee shall fix a Special Record Date
         for the payment of such Defaulted Interest which shall be not more than
         15 days and not less than 10 days prior to the date of the proposed
         payment and not less than 10 days after the receipt by the Trustee of
         the notice of the proposed payment. The Trustee shall promptly notify
         the Corporation of such Special Record Date and, in the name and at the
         expense of the Corporation, shall cause notice of the proposed payment
         of such Defaulted Interest and the Special Record Date therefor to be
         given to each Holder of Securities of such series in the manner set
         forth in Section 106, 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 of such series (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 Corporation may make payment of any Defaulted Interest
         on the Securities of any series in any other lawful manner not
         inconsistent with the requirements of any securities exchange, if any,
         on which such Securities may be listed, and upon such notice as may be
         required by such exchange, if, after notice given by the Corporation 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.

SECTION 308.      PERSONS DEEMED OWNERS.

         Prior to due presentment of a Security for registration of transfer,
the Corporation, the Trustee and any agent of the Corporation 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 any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Corporation, the Trustee nor any agent of the Corporation or the Trustee shall
be affected by notice to the contrary.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on


                                       29
<PAGE>   36

account of beneficial ownership interest of a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

         Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any Agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depositary, as a Holder, with respect to
such Global Security or impair, as between such depositary and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depositary as Holder of
such Global Security.

SECTION 309.      CANCELLATION.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Corporation may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Corporation may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Corporation has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of in its customary manner or
as directed by a Company Order; provided, however, that the Trustee shall not be
required to destroy such canceled Securities.

SECTION 310.      COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 311.      CUSIP NUMBERS.

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

                           SATISFACTION AND DISCHARGE

SECTION 401.      SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Corporation, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

                  (1) either

                           (A) all Securities theretofore authenticated and
                  delivered (other than (i) Securities which have been
                  destroyed, lost or stolen and which have been replaced or paid
                  as provided in Section 306 and (ii) Securities for whose
                  payment money has theretofore been deposited in trust or
                  segregated and held in trust by the Corporation and thereafter
                  repaid to the Corporation or discharged from such trust, as
                  provided in Section 1003) have been delivered to the Trustee
                  for cancellation; or

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

                                    (i) have become due and payable, or

                                    (ii) will become due and payable at their
                           Stated Maturity within one year, or

                                    (iii) are to be called for redemption within
                           one year under arrangements satisfactory to the
                           Trustee for the giving of notice of redemption by the
                           Trustee in the name, and at the expense, of the
                           Corporation,

                  and the Corporation, in the case of (i), (ii) or (iii) above,
                  has deposited or caused to be deposited with the Trustee as
                  trust funds in trust for the purpose (i) money in an amount,
                  (ii) Government Obligations (as defined in Section 1304) which
                  through the scheduled payment of principal and interest in
                  respect thereof in accordance with their terms will provide,
                  not later than the due date of any payment, money in an
                  amount, or (iii) a combination thereof, sufficient, in the
                  case of (ii) or (iii), in the opinion of a nationally
                  recognized firm of independent public accountants expressed in
                  a written certification thereof delivered to the Trustee, to
                  pay and discharge, and which shall be applied by the Trustee
                  to pay and discharge, the entire indebtedness on such
                  Securities not theretofore delivered to the Trustee for
                  cancellation, for principal and any premium and interest to
                  the


                                       31
<PAGE>   38

                  date of such deposit (in the case of Securities which have
                  become due and payable) or to the Stated Maturity or
                  Redemption Date, as the case may be;

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

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

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Corporation to the Trustee under Section 607, the obligations
of the Corporation to any Authenticating Agent under Section 614 and, if money
shall have been deposited with the Trustee pursuant to subclause (B) of Clause
(1) of this Section, the obligations of the Trustee under Section 402 and the
last paragraph of Section 1003 shall survive such satisfaction and discharge.

SECTION 402.      APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Corporation acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                    REMEDIES

SECTION 501.      EVENTS OF DEFAULT.

         "Event of Default," wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless it is inapplicable to a particular series or is specifically deleted or
modified in the Board Resolution (or action taken pursuant thereto), Officer's
Certificate or supplemental indenture under which such series of Securities is
issued or has been deleted or modified in an indenture supplemental hereto:

                  (1) default in the payment of any interest upon any Security
         of that series when it becomes due and payable, and continuance of such
         default for a period of 30 days; provided, however, that if the
         Corporation is permitted by the terms of the Securities of such series
         to defer the payment in question, the date on which such payment is due
         and payable shall be the date on which the Corporation is required to


                                       32
<PAGE>   39

         make payment following such deferral, if such deferral has been elected
         pursuant to the terms of the Securities; or

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

                  (3) default in the making of any sinking fund payment, when
         and as due by the terms of a Security of that series, and continuance
         of such default for a period of 60 days; or

                  (4) default in the performance, or breach, of any covenant of
         the Corporation in this Indenture (other than a covenant a default in
         whose performance or whose breach is elsewhere in this Section
         specifically dealt with or which has expressly been included in this
         Indenture solely for the benefit of series of Securities other than
         that series), and continuance of such default or breach for a period of
         90 days after there has been given, by registered or certified mail, to
         the Corporation by the Trustee or to the Corporation and the Trustee by
         the Holders of at least 25% in principal amount of the Outstanding
         Securities of that series a written notice specifying such default or
         breach and requiring it to be remedied and stating that such notice is
         a "Notice of Default" hereunder, unless the Trustee, or the Trustee and
         the Holders of a principal amount of Securities of such series not less
         than the principal amount of Securities the Holders of which gave such
         notice, as the case may be, shall agree in writing to an extension of
         such period prior to its expiration; provided, however, that the
         Trustee, or the Trustee and the Holders of such principal amount of
         Securities of such series, as the case may be, shall be deemed to have
         agreed to an extension of such period if corrective action is initiated
         by the Corporation within such period and is being diligently pursued;
         or

                  (5) the entry by a court having jurisdiction in the premises
         of (A) a decree or order for relief in respect of the Corporation in an
         involuntary case or proceeding under any applicable federal or state
         bankruptcy, insolvency, reorganization or other similar law or (B) a
         decree or order adjudging the Corporation a bankrupt or insolvent, or
         approving as properly filed a petition seeking reorganization,
         arrangement, adjustment or composition of or in respect of the
         Corporation under any applicable federal or state law, or appointing a
         custodian, receiver, liquidator, assignee, trustee, sequestrator or
         other similar official of the Corporation or of any substantial part of
         its property, or ordering the winding-up or liquidation of its affairs,
         and the continuance of any such decree or order for relief or any such
         other decree or order unstayed and in effect for a period of 90
         consecutive days; or

                  (6) the commencement by the Corporation of a voluntary case or
         proceeding under any applicable federal or state bankruptcy,
         insolvency, reorganization or other similar law or of any other case or
         proceeding to be adjudicated a bankrupt or insolvent, or the consent by
         it to the entry of a decree or order for relief in respect of the
         Corporation in an involuntary case or proceeding under any applicable
         federal or state bankruptcy,


                                       33
<PAGE>   40

         of any bankruptcy or insolvency case or proceeding against it, or the
         filing by it of a petition or answer or consent seeking reorganization
         or relief under any applicable federal or state law, or the consent by
         it to the filing of such petition or to the appointment of or taking
         possession by a custodian, receiver, liquidator, assignee, trustee,
         sequestrator or other similar official of the Corporation or of any
         substantial part of its property, or the making by it of an assignment
         for the benefit of creditors, or the admission by it in writing of its
         inability to pay its debts generally as they become due, or the
         authorization of any such action by the Board of Directors; or

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

SECTION 502.      ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount of all the Securities
of that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Corporation (and to the Trustee if given by Holders), and upon
any such declaration such principal amount (or specified amount) shall become
immediately due and payable.

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

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

                          (A) all overdue interest on all Securities of that
                  series,

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

                          (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the rate or rates
                  prescribed therefor in such Securities, and


                                       34
<PAGE>   41
                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel;

         and

                  (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 513.

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

SECTION 503.      COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT
                  BY TRUSTEE.

         The Corporation covenants that if

                  (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 Corporation will, upon demand of the Trustee, 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 any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

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

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement


                                       35
<PAGE>   42

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 504.      TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of any judicial proceeding relative to the Corporation (or any
other obligor upon the Securities), its property or its 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 607.

         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 a creditors'
or other similar committee.

SECTION 505.      TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of 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 506.      APPLICATION OF MONEY COLLECTED.

         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 any premium
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 607;


                                       36
<PAGE>   43

                  Second: To the payment of the amounts then due and unpaid for
         principal of and any premium and interest on the Securities in respect
         of which or for the benefit of which such money has been collected,
         ratably, without preference or priority of any kind, according to the
         amounts due and payable on such Securities for principal and any
         premium and interest, respectively; and

                  Third: To the payment of the balance, if any, to the
         Corporation.

SECTION 507.      LIMITATION ON SUITS.

         No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless

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

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities of all affected series, considered as one
         class, or, in the case of an Event of Default of the character
         specified above in Section 501(1), (2) or (3), that series, shall have
         made written request to the Trustee to institute proceedings in respect
         of such Event of Default in its own name as Trustee hereunder;

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

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

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of all
         affected series, considered as one class, or, in the case of an Event
         of Default of the character specified above in Section 501(1), (2) or
         (3), that series,

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

SECTION 508.      UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
                  AND INTEREST.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated


                                       37
<PAGE>   44

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

SECTION 509.      RESTORATION OF RIGHTS AND REMEDIES.

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

SECTION 510.      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 511.      DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.

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

SECTION 512.      CONTROL BY HOLDERS.

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

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


                                       38
<PAGE>   45

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

                  (3) subject to the provisions of Section 601, the Trustee
         shall have the right to decline to follow any such direction if the
         Trustee in good faith shall, by a Responsible Officer or Officers of
         the Trustee, determine that the proceeding so directed would involve
         the Trustee in personal liability.

         If an Event of Default is continuing with respect to all Outstanding
Securities, the Holders of a majority in principal amount of all the Outstanding
Securities, considered as one class, shall have the right to make such
direction, and not the Holders of Securities of any one series.

SECTION 513.      WAIVER OF PAST DEFAULTS.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of all series with respect to which any default under the
Indenture shall have occurred and be continuing (voting as one class) may, on
behalf of the Holders of all Securities of all such series, waive such past
default under the Indenture and its consequences, except a default

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

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

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

SECTION 514.      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, including legal fees and expenses 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 (i) any suit
instituted by the Trustee, (ii) any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or (iii) any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest on any Security on or after the


                                       39
<PAGE>   46

respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

SECTION 515.      WAIVER OF STAY OR EXTENSION LAWS.

         The Corporation covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any 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 Corporation (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any such
law and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE VI.
                                   THE TRUSTEE

SECTION 601.      CERTAIN DUTIES AND RESPONSIBILITIES.

         The duties and responsibilities of the Trustee shall be as provided in
this Indenture and no duties shall be inferred or implied against the Trustee.
Notwithstanding the foregoing, no provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. 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 602.      NOTICE OF DEFAULTS.

         If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(4) with respect to Securities of such series, no 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, an Event of Default with respect
to Securities of such series.

SECTION 603.      CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 601:

                  (1) the Trustee may conclusively rely and shall be fully
         protected in acting or refraining from acting upon any resolution,
         certificate, statement, instrument, opinion,


                                       40
<PAGE>   47

         report, notice, request, direction, consent, order, bond, debenture,
         note or other paper or document believed by it to be genuine and to
         have been signed or presented by the proper party or parties;

                  (2) any request or direction of the Corporation mentioned
         herein shall be sufficiently evidenced by a Company Request or Company
         Order or as otherwise expressly provided herein, and any resolution of
         the Board of Directors shall be sufficiently evidenced by a Board
         Resolution;

                  (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officer's
         Certificate;

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

                  (5) the Trustee shall be under no obligation to exercise any
         of the rights or powers vested in it by this Indenture at the request
         or direction of any of the Holders pursuant to this Indenture, unless
         such Holders shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction;

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

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

SECTION 604.      NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Corporation, and neither the Trustee nor


                                       41
<PAGE>   48

any Authenticating Agent assumes any responsibility for their correctness. The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent
shall be accountable for the use or application by the Corporation of Securities
or the proceeds thereof.

SECTION 605.      MAY HOLD SECURITIES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Corporation, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Corporation with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 606.      MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Corporation.

SECTION 607.      COMPENSATION AND REIMBURSEMENT.

         The Corporation agrees:

                  (1) to pay to the Trustee from time to time such compensation
         as shall be agreed to in writing between the Corporation and the
         Trustee for all services rendered by it hereunder (which compensation
         shall not be limited by any provision of law in regard to the
         compensation of a trustee of an express trust);

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

                  (3) to indemnify the Trustee for, and to hold it harmless
         against, any and all loss, liability, damage, claim or expense,
         including taxes (other than taxes based on the income of the Trustee)
         incurred without negligence, willful misconduct or bad faith on its
         part, arising out of or in connection with the acceptance or
         administration of the trust or trusts hereunder, including the costs
         and expenses of defending itself against any claim whether asserted by
         the Corporation, a Holder or any other Person or liability in
         connection with the exercise or performance of any of its powers or
         duties hereunder.


                                       42
<PAGE>   49

         The Trustee shall have a lien prior to the Securities upon all property
and funds held by it hereunder for any amount owing it or any predecessor
Trustee pursuant to this Section 607, except with respect to funds held in trust
for the benefit of the Holders of particular Securities.

         Without limiting any rights available to the Trustee under applicable
law, when the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

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

SECTION 608.      CONFLICTING INTERESTS.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.

SECTION 609.      CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be a Trustee hereunder with respect to the
Securities of each series, which may be Trustee hereunder for Securities of one
or more other series. Each Trustee shall be a Person that is eligible pursuant
to the Trust Indenture Act to act as such and has a combined capital and surplus
of at least $50,000,000. If any such Person publishes reports of condition at
least annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section and to the extent
permitted by the Trust Indenture Act, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee
with respect to the Securities of any series shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

SECTION 610.      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

         The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Corporation. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after


                                       43
<PAGE>   50

the giving of such notice of resignation, the resigning Trustee may petition, at
the expense of the Corporation, any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Corporation. Upon such removal, the Corporation may petition, at its expense,
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

         If at any time:

                  (1) the Trustee shall fail to comply with Section 608 after
         written request therefor by the Corporation or by any Holder who has
         been a bona fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 609
         and shall fail to resign after written request therefor by the
         Corporation or by any such Holder, or

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

then, in any such case, (A) the Corporation by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

         If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Corporation, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Corporation and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Corporation. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the


                                       44
<PAGE>   51

Corporation or the Holders and accepted appointment in the manner required by
Section 611, any Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         The Corporation shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series to all
Holders of Securities of such series in the manner provided in Section 106. Each
notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

SECTION 611.      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Corporation and to the retiring Trustee
an instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee; but, on the
request of the Corporation 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.

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


                                       45
<PAGE>   52

the Securities of that or those series to which the appointment of such
successor Trustee relates; but, on request of the Corporation or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

         Upon request of any such successor Trustee, the Corporation shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in the first or second preceding paragraph, as the case may be.

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

SECTION 612.      MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

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

SECTION 613.      PREFERENTIAL COLLECTION OF CLAIMS AGAINST CORPORATION.

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

SECTION 614.      APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee may appoint an Authenticating Agent or Agents acceptable to
the Corporation with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall


                                       46
<PAGE>   53

be acceptable to the Corporation and shall at all times be a corporation
organized and doing business under the laws of the United States of America, any
State thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by federal or state
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

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

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Corporation. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Corporation. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Corporation and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         The Corporation agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

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


                                       47

         This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

Corporation may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date
on and/or after which such action shall be taken or such omission shall be
effective. The Trustee shall not be liable to the Corporation for any action
taken by, or omission of, the Trustee in accordance with a proposal included in
such application on or after the date specified in such application (which date
shall not be less than five Business Days after the date any officer of the
Corporation actually receives such application, unless any such officer shall
have consented in writing to any earlier date) unless prior to taking any such
action (or the effective date in the case of an omission), the Trustee shall
have received written instructions in response to such application specifying
the action to be taken or omitted.

SECTION 702.      PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

         The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

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

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

SECTION 703.      REPORTS BY TRUSTEE.

         The Trustee shall transmit to Holders such reports concerning the
Trustee and its actions under this Indenture as may be required pursuant to the
Trust Indenture Act at the times and in the manner provided pursuant thereto. If
required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within
60 days after each May 15 following the date of this Indenture, deliver to
Holders a brief report, dated as of such May 15, which complies with the

Trustee within 15 days after the same is so required to be filed with the
Commission. Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not

SECTION 801.      CORPORATION MAY CONSOLIDATE, ETC., ONLY ON CERTAIN TERMS.

         The Corporation shall not consolidate with or merge into any other
Person or convey, transfer or lease its properties and assets substantially as
an entirety to any Person, and no Person shall consolidate with or merge into
the Corporation or convey, transfer or lease its properties and assets
substantially as an entirety to the Corporation, unless:

                  (1) in case the Corporation shall consolidate with or merge
         into another Person or convey, transfer or lease its properties and
         assets substantially as an entirety to any Person, the Person formed by
         such consolidation or into which the Corporation is merged or the
         Person which acquires by conveyance or transfer, or which leases, the
         properties and assets of the Corporation substantially as an entirety
         shall be a corporation, partnership, limited liability company or trust
         organized and existing under the laws of the United States of America
         or any State thereof or the District of Columbia and shall expressly
         assume, by an indenture supplemental hereto, executed and delivered to
         the Trustee, in form satisfactory to the Trustee, the due and punctual
         payment of the principal of (and premium, if any) and interest on all
         the Securities and the performance of every covenant of this Indenture
         on the part of the Corporation to be performed or observed;

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

                  (3) such other conditions as may be specified pursuant to

         Certificate and an Opinion of Counsel, each stating that such
         consolidation, merger, conveyance or transfer and, if a supplemental
         indenture is required in connection with such transaction, such
         supplemental indenture comply with this Article and that all conditions
         precedent herein provided for relating to such transaction have been
         complied with; and the Trustee, subject to Section 601, may rely upon
         such Officer's Certificate and Opinion of Counsel as conclusive
         evidence that such transaction complies with this Section 801.

SECTION 802.      SUCCESSOR SUBSTITUTED.

         Upon any consolidation of the Corporation with, or merger of the
Corporation into, any other Person or any conveyance or transfer of the
properties and assets of the Corporation as an entirety or substantially as an
entirety in accordance with Section 801, the successor Person formed by such
consolidation or into which the Corporation is merged or to which such
conveyance or transfer is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Corporation under this Indenture with the
same effect as if such successor


                                       50
<PAGE>   57

Person had been named as the Corporation herein, and thereafter the predecessor
Person shall be relieved of all obligations and covenants under this Indenture
and the Securities.

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

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

         of the Corporation herein and in the Securities; or

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

                  (3) to add any additional Events of Default for the benefit of
         the Holders of all or any series of Securities (and if such additional
         Events of Default are to be for the benefit of less than all series of
         Securities, stating that such additional Events of Default are
         expressly being included solely for the benefit of such series); or

<PAGE>   58

                  (4) to add to or change any of the provisions of this
         Indenture to such extent as shall be necessary to permit or facilitate
         the issuance of Securities in bearer form, registrable or not

         this Indenture in respect of one or more series of Securities; provided
         that any such addition, change or elimination (A) shall neither (i)
         apply to any Security of any series created prior to the execution of
         such supplemental indenture and entitled to the benefit of such
         provision nor (ii) modify the rights of the Holder of any such Security
         with respect to such provision or (B) shall become effective only when
         there is no such Security Outstanding; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
         as permitted by Sections 201 and 301; or

                  (8) to evidence and provide for the acceptance of appointment
         hereunder by a successor Trustee with respect to the Securities of one
         or more series and to add to or change any of the provisions of this

         administration of the trusts hereunder by more than one Trustee,
         pursuant to the requirements of Section 611; or

                  (9) to cure any ambiguity, to correct or supplement any
         provision herein which may be defective or inconsistent with any other
         provision herein, or to make any other provisions with respect to
         matters or questions arising under this Indenture; provided that such
         action pursuant to this Clause (9) shall not adversely affect the
         interests of the Holders of Securities of any series in any material
         respect.

SECTION 902.      SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of all series affected by such
supplemental indenture (voting as one class), by Act of said Holders delivered
to the Corporation and the Trustee, the Corporation, when authorized by a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture, or modifying in any manner the rights of the Holders of
Securities under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby,

                  (1) change the Stated Maturity of the principal of, or any
         installment of principal of or interest on, any Security (other than
         pursuant to the terms of such Security), or reduce the principal amount
         thereof or the rate of interest thereon or any premium payable upon the
         redemption thereof, or reduce the amount of the principal of


                                       52
<PAGE>   59

         an Original Issue Discount Security or any other Security which would
         be due and payable upon a declaration of acceleration of the Maturity
         thereof pursuant to Section 502 or change the coin or currency in which
         any Security or any premium or interest thereon is payable, or impair
         the right to institute suit for the enforcement of any such payment on
         or after the Stated Maturity thereof (or, in the case of redemption, on
         or after the Redemption Date), or

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

                  (3) modify any of the provisions of this Section, Section 513
         or Section 1006, except to increase any such percentage or to provide
         that certain other provisions of this Indenture cannot be modified or
         waived without the consent of the Holder of each Outstanding Security
         affected thereby; provided, however, that this clause shall not be
         deemed to require the consent of any Holder with respect to changes in
         the references to "the Trustee" and concomitant changes in this Section
         and Section 1006, or the deletion of this proviso, in accordance with
         the requirements of Sections 611 and 901(8).

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

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

SECTION 903.      EXECUTION OF SUPPLEMENTAL INDENTURES.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

SECTION 904.      EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this


                                       53
<PAGE>   60

Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby.

SECTION 905.      CONFORMITY WITH TRUST INDENTURE ACT.

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

SECTION 906.      REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

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

SECTION 907.  SUBORDINATION UNIMPAIRED.

         This Indenture may not be amended to alter the subordination of any of
the Outstanding Securities without the written consent of each holder of Senior
Indebtedness then outstanding that would be adversely affected thereby.

                                   ARTICLE X.
                                   COVENANTS

SECTION 1001.     PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

         The Corporation covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

SECTION 1002.     MAINTENANCE OF OFFICE OR AGENCY.

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


                                       54
<PAGE>   61

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

SECTION 1003.     MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

         If the Corporation shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and 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 Corporation shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium or interest on any Securities of that series, 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 Corporation will promptly notify the Trustee of its action or
failure so to act.

         The Corporation will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (1) hold all sums
held by it for the payment of the principal of (and premium, if any) or interest
on Securities in trust for the benefit of the Persons entitled thereto until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, (2) give the Trustee notice of any default by the Corporation (or any
other obligor upon the Securities) in the making of any payment of principal
(and premium, if any) or interest, (3) comply with the provisions of the Trust
Indenture Act applicable to it as a Paying Agent and (4) during the continuance
of any default by the Corporation (or any other obligor upon the Securities of
that series) in the making of any payment in respect of the Securities of that
series, upon the written request of the Trustee, forthwith pay to the Trustee
all sums held in trust by such- Paying Agent for payment in respect of the
Securities of that series.

         The Corporation may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust hereunder by the Corporation 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
Corporation 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.


                                       55
<PAGE>   62

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Corporation, in trust for the payment of the principal of or any premium
or interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Corporation on Company Request, or (if then held by the Corporation)
shall be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look only to the Corporation for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Corporation 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 Corporation 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, 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
Corporation.

SECTION 1004.     CORPORATE EXISTENCE.

         Subject to Article Eight, the Corporation will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises.

SECTION 1005.     STATEMENT BY OFFICERS AS TO DEFAULT.

         The Corporation will deliver to the Trustee, on or before October 15 of
each calendar year or on or before such other day in each calendar year as the
Corporation and the Trustee may from time to time agree upon, an Officer's
Certificate, stating whether or not to the best knowledge of the signers thereof
the Corporation 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 Corporation
shall be in default, specifying all such defaults and the nature and status
thereof of which they may have knowledge.

<PAGE>   63

SECTION 1006.     WAIVER OF CERTAIN COVENANTS.

         Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Corporation may, with respect to the Securities
of any series, omit in any particular instance to comply with any term,
provision or condition set forth in any covenant provided pursuant to Section
301(19), 901(2) or 901(7) for the benefit of the Holders of such series if
before the time for such compliance the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series shall, by Act of
such Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Corporation and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.

                                  ARTICLE XI.
                            REDEMPTION OF SECURITIES

SECTION 1101.     APPLICABILITY OF ARTICLE.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1102.     ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Corporation to redeem any Securities shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities. In case of any redemption at the election of
the Corporation, the Corporation shall, at least 45 days prior to the Redemption
Date fixed by the Corporation (unless a shorter notice shall be satisfactory to
the Trustee), notify the Trustee of such Redemption Date, of the principal
amount of Securities of such series to be redeemed and, if applicable, of the
tenor of the Securities to be redeemed. In the case of any redemption of
Securities (A) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, or (B)
pursuant to an election of the Corporation which is subject to a condition
specified in the terms of such Securities or elsewhere in this Indenture, the
Corporation shall furnish the Trustee with an Officer's Certificate evidencing
compliance with such restriction or condition.

SECTION 1103.     SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate


                                       57
<PAGE>   64

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

         The Trustee shall promptly notify the Corporation in writing of the
Securities selected for redemption as aforesaid and, in the case of any
Securities selected for partial redemption as aforesaid, the principal amount
thereof to be redeemed.

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

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

SECTION 1104.     NOTICE OF REDEMPTION.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

         All notices of redemption shall identify the Securities to be redeemed
(including CUSIP number(s)) and shall state:

                           (1) the Redemption Date;

                           (2) the Redemption Price;

                           (3) if less than all the Outstanding Securities of
                  any series and of a specified tenor consisting of more than a
                  single Security are to be redeemed, the identification (and,
                  in the case of partial redemption of any such Securities, the
                  principal amounts) of the particular Securities to be redeemed
                  and, if less than all the Outstanding Securities of any series
                  and of a specified tenor consisting of a single Security are
                  to be redeemed, the principal amount of the particular
                  Security to be redeemed;


                                       58
<PAGE>   65

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

                           (5) the place or places where each such Security is
                  to be surrendered for payment of the Redemption Price and
                  accrued interest, if any, unless it shall have been specified
                  as contemplated by Section 301 with respect to such Securities
                  that such surrender shall not be required;

                           (6) that the redemption is for a sinking fund, if
                  such is the case; and

                           (7) such other matters as the Corporation shall deem
                  desirable or appropriate.

         Unless otherwise specified with respect to any Securities in accordance
with Section 301, with respect to any redemption of Securities at the election
of the Corporation, unless, upon the giving of notice of such redemption,
Defeasance shall have been effected with respect to such Securities pursuant to
Section 1302, such notice may state that such redemption shall be conditional
upon the receipt by the Trustee or the Paying Agent(s) for such Securities, on
or prior to the date fixed for such redemption, of money sufficient to pay the
principal of and any premium and interest on such Securities and that if such
money shall not have been so received such notice shall be of no force or effect
and the Corporation shall not be required to redeem such Securities. In the
event that such notice of redemption contains such a condition and such money is
not so received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Trustee or Paying Agent(s) for the
Securities otherwise to have been redeemed shall promptly return to the Holders
thereof any of such Securities which had been surrendered for payment upon such
redemption.

         Notice of redemption of Securities to be redeemed at the election of
the Corporation, and any notice of non-satisfaction of redemption as aforesaid,
shall be given by the Corporation or, at the Corporation's request, by the
Trustee in the name and at the expense of the Corporation. Subject to the
preceding paragraph, any such notice of redemption shall be irrevocable.

SECTION 1105.     DEPOSIT OF REDEMPTION PRICE.

         On or prior to the Redemption Date specified in the notice of
redemption given as provided in Section 1104, the Corporation will deposit with
the Trustee or with one or more Paying Agents (or if the Corporation is acting
as its own Paying Agent, the Corporation will segregate and hold in trust as
provided in Section 1003) an amount of money sufficient to pay the Redemption
Price of; and any accrued interest on, all the Securities which are to be
redeemed on that date.


                                       59
<PAGE>   66
SECTION 1106.     SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, and the
conditions, if any, set forth in such notice having been satisfied, the
Securities or portions thereof 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, in the case of an unconditional notice of redemption,
the Corporation shall default in the payment of the Redemption Price and accrued
interest, if any) such Securities or portions thereof, if interest-bearing,
shall cease to bear interest. Upon surrender of any such Security for redemption
in accordance with said notice, such Security or portion thereof shall be paid
by the Corporation at the Redemption Price, together with accrued interest, if
any, to the Redemption Date; provided, however, that no such surrender shall be
a condition to such payment if so specified as contemplated by Section 301 with
respect to such Security, and provided further that, unless otherwise specified
as contemplated by Section 301, installments of interest whose Stated Maturity
is on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

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

SECTION 1107.     SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Corporation or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Corporation and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Corporation shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities of the same series
and of like tenor, 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 XII.
                                  SINKING FUNDS

SECTION 1201.     APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

         The minimum amount of any sinking fund payment provided for by the
terms of any Securities is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of such Securities is herein referred to



                                       60
<PAGE>   67

as an "optional sinking fund payment." If provided for by the terms of any
Securities, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities as provided for by the terms of such
Securities.

SECTION 1202.     SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         The Corporation (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Corporation pursuant to the terms of such Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 1203.     REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 45 days prior to each sinking fund payment date for any
Securities, the Corporation will deliver to the Trustee an Officer's Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and stating the basis for such credit and that such Securities have
not been previously so credited and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 days prior to each such sinking
fund payment date, the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Corporation in the manner provided in Section 1104. Such notice having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1105 and 1106.

                                 ARTICLE XIII.
                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301.     APPLICABILITY OF ARTICLE.

         Unless, pursuant to Section 301, provision is made that either or both
of (A) defeasance of any Securities or any series of Securities under Section
1302 and (B) covenant defeasance of any Securities or any series of Securities
under Section 1303 shall not apply to such Securities of a series, then the
provisions of either or both of Sections 1302 and Section 1303, as the case may
be, together with Sections 1304 and 1305, shall be applicable to the Outstanding
Securities of such series upon compliance with the conditions set forth below in
this Article.

<PAGE>   68

SECTION 1302.     DEFEASANCE AND DISCHARGE.

         The Corporation may cause itself to be discharged from its obligations
with respect to any Securities or any series of Securities on and after the date
the conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Corporation
shall be deemed to have paid and discharged the entire indebtedness represented
by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Corporation, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder: (1) the rights of Holders of such
Securities to receive, solely from the trust fund described in Section 1304 and
as more fully set forth in such Section, payments in respect of the principal of
and any premium and interest on such Securities when payments are due, (2) the
Corporation's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003 and with respect to the Trustee under Section 607, (3)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(4) this Article. Subject to compliance with this Article, Defeasance with
respect to any Securities or any series of Securities by the Corporation is
permitted under this Section 1302 notwithstanding the prior exercise by the
Corporation of its rights under Section 1303 with respect to such Securities.
Following a Defeasance, payment of such Securities may not be accelerated
because of an Event of Default.

SECTION 1303.     COVENANT DEFEASANCE.

         The Corporation may cause itself to be released from its obligations
under any covenants provided pursuant to Section 301(19), 901(2), 901(6) or
901(7) with respect to any Securities or any series of Securities for the
benefit of the Holders of such Securities and the occurrence of any event
specified in Sections 501(4) (with respect to any such covenants provided
pursuant to Section 301(19), 901(2), 901(6) or 901(7)) or 501(7) shall be deemed
not to be or result in an Event of Default with respect to such Securities as
provided in this Section, in each case on and after the date the conditions set
forth in Section 1304 are satisfied (hereinafter called "Covenant Defeasance").
For this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Corporation may omit to comply with and shall have no liability
in respect of any term, condition or limitation set forth in any such specified
Section (to the extent so specified in the case of Section 501(4)), whether
directly or indirectly by reason of any reference elsewhere herein to any such
Section or by reason of any reference in any such Section to any other provision
herein or in any other document, but the remainder of this Indenture and such
Securities shall be unaffected thereby.

SECTION 1304.     CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions to the application of Section
1302 or Section 1303 to any Securities or any series of Securities, as the case
may be:

                  (1) The Corporation shall irrevocably have deposited or caused
         to be deposited with the Trustee as trust funds in trust for the
         purpose of making the following



                                       62
<PAGE>   69

         payments, specifically pledged as security for, and dedicated solely
         to, the benefit of the Holders of such Securities, (A) money in an
         amount, or (B) Government Obligations which through the scheduled
         payment of principal and interest in respect thereof in accordance with
         their terms will provide, not later than the due date of any payment,
         money in an amount, or (C) a combination thereof, sufficient, in the
         case of (B) or (C), in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge, and which shall
         be applied by the Trustee to pay and discharge, the principal of and
         any premium and interest on such Securities on the respective Stated
         Maturities or on any Redemption Date established pursuant to Clause (3)
         below, in accordance with the terms of this Indenture and such
         Securities. As used herein, "Government Obligation" means (x) any
         security which is (i) a direct obligation of the United States of
         America or the government which issued the foreign currency in which
         such Securities are payable, for the payment of which its full faith
         and credit is pledged or (ii) an obligation of a Person controlled or
         supervised by and acting as an agency or instrumentality of the United
         States of America or such government which issued the foreign currency
         in which such Securities are payable, the payment of which is
         unconditionally guaranteed as a full faith and credit obligation by the
         United States of America or such other government, which, in either
         case (i) or (ii), is not callable or redeemable at the option of the
         issuer thereof, and (y) any depositary receipt issued by a bank (as
         defined in Section 3(a)(2) of the Securities Act) as custodian with
         respect to any Government Obligation which is specified in clause (x)
         above and held by such bank for the account of the holder of such
         depositary receipt, or with respect to any specific payment of
         principal of or interest on any Government Obligation which is so
         specified and held, provided that (except as required by law) such
         custodian is not authorized to make any deduction from the amount
         payable to the holder of such depositary receipt from any amount
         received by the custodian in respect of the Government Obligation or
         the specific payment of principal or interest evidenced by such
         depositary receipt.

                  (2) No event which is, or after notice or lapse of time or
         both would become, an Event of Default with respect to such Securities
         or any other Securities shall have occurred and be continuing at the
         time of such deposit or, with regard to any such event specified in
         Sections 501(5) and (6), at any time on or prior to the 90th day after
         the date of such deposit (it being understood that this condition shall
         not be deemed satisfied until after such 90th day).

                  (3) If the Securities are to be redeemed prior to Stated
         Maturity (other than from mandatory sinking fund payments or analogous
         payments), notice of such redemption shall have been duly given
         pursuant to this Indenture or provision therefor satisfactory to the
         Trustee shall have been made.

                  (4) The Corporation shall have delivered to the Trustee an
         Officer's Certificate and an Opinion of Counsel, each stating that all
         conditions precedent with respect to such Defeasance or Covenant
         Defeasance have been complied with.

SECTION 1305.     DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN
                  TRUST; MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (including the proceeds thereof) deposited with
the Trustee pursuant to Section 1304 in respect of any Securities shall be held
in trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Corporation acting as its own Paying Agent) as
the Trustee may determine, to the Holders of such Securities, of all sums due
and to become due thereon in respect of principal and any premium and interest,
but money so held in trust need not be segregated from other funds except to the
extent required by law.

         The Corporation shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Corporation from time to time upon Company Request
any money or Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

                                  ARTICLE XIV.
                                  SUBORDINATION

SECTION 1401.     SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS.

         Except as otherwise specified as contemplated by Section 301 for any
series of Securities, the Corporation covenants and agrees, and each Holder of a
Security, by his acceptance thereof, likewise covenants and agrees, that the
indebtedness represented by the Securities of any series and the payment of the
principal of and any premium or interest on each and all of the Securities of
each series is subordinate, to the extent and in the manner hereinafter set
forth, in right of payment to the prior payment in full of all Senior
Indebtedness. Senior Indebtedness shall continue to be Senior Indebtedness and
entitled to the benefits of these subordination provisions irrespective of any
amendment, modification or waiver of any term of the Senior Indebtedness or
extension or renewal of the Senior Indebtedness.

         In the event (a) of any payment by, or distribution of assets of, the
Corporation of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution, winding-up, liquidation or reorganization of
the Corporation, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, or (b) subject to the provisions of Section
1402 that (i) a default shall have occurred and be continuing with respect to
the payment



                                       64
<PAGE>   71

of principal, interest or any other monetary amounts due and payable on any
Senior Indebtedness and such default shall have continued beyond the period of
grace, if any, specified in the instrument evidencing such Senior Indebtedness
(and the Trustee shall have received written notice thereof from the Corporation
or one or more holders of Senior Indebtedness or their representative or
representatives or the trustee or trustees under any indenture pursuant to which
any such Senior Indebtedness may have been issued), or (ii) the maturity of any
Senior Indebtedness shall have been accelerated because of a default in respect
of such Senior Indebtedness (and the Trustee shall have received written notice
thereof from the Corporation or one or more holders of Senior Indebtedness or
their representative or representatives or the trustee or trustees under any
indenture pursuant to which any such Senior Indebtedness may have been issued),
then:

         (a) the holders of all Senior Indebtedness shall first be entitled to
receive, in the case of (a) above, payment of all amounts due or to become due
upon all Senior Indebtedness (including interest after the commencement of any
bankruptcy proceeding at the rate specified in the applicable Senior
Indebtedness) and, in the case of subclauses (i) and of clause (b) above,
payment of all amounts due thereon, or provision shall be made for such payment
in money or money's worth, before the Holders of any of the Securities are
entitled to receive any payment on account of the principal of or any premium or
interest on the indebtedness evidenced by the Securities, including, without
limitation, any payments made pursuant to Article Eleven or Article Twelve;

         (b) any payment by, or distribution of assets of, the Corporation of
any kind or character, whether in cash, property or securities, to which the
Holders of any of the Securities would be entitled except for the provisions of
this Article, including any such payment or distribution which may be payable or
deliverable by reason of the payment of any other indebtedness of the
Corporation being subordinated to the payment of such Securities, shall be paid
or delivered by the Person making such payment or distribution, whether a
trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly
to the holders of such Senior Indebtedness or their representative or
representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Senior Indebtedness may have been issued,
ratably according to the aggregate amounts remaining unpaid on account of such
Senior Indebtedness held or represented by each, to the extent necessary to make
payment in full of all Senior Indebtedness remaining unpaid after giving effect
to any concurrent payment or distribution (or provision therefor) to the holders
of such Senior Indebtedness, before any payment or distribution is made to the
Holders of the indebtedness evidenced by such Securities;

         (c) in the event that, notwithstanding the foregoing, any payment by,
or distribution of assets of, the Corporation of any kind or character, whether
in cash, property or securities, including any such payment or distribution
which may be payable or deliverable by reason of the payment of any other
indebtedness of the Corporation being subordinated to the payment of such
Securities, in respect of principal of or any premium or interest on any of the
Securities or in connection with the repurchase by the Corporation of any of the
Securities, shall be received by the Trustee or the Holders of any of the
Securities when such payment or distribution is



                                       65
<PAGE>   72

prohibited pursuant to this Section, such payment or distribution shall be paid
over to the holders of such Senior Indebtedness or their representative or
representatives or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any such Senior Indebtedness may have been
issued, ratably as aforesaid, for application to the payment of all Senior
Indebtedness remaining unpaid until all such Senior Indebtedness shall have been
paid in full, after giving effect to any concurrent payment or distribution (or
provision therefor) to the holders of such Senior Indebtedness; and

         (d) the Corporation also may not make any payment upon or in respect of
the Securities if (i) a default in the payment of the principal of, premium, if
any, or interest on Senior Indebtedness occurs and is continuing beyond any
applicable period of grace or (ii) any other default occurs and is continuing
with respect to Designated Senior Indebtedness that currently, or with the
passage of time or giving of notice, permits holders of the Designated Senior
Indebtedness as to which such default relates to accelerate its maturity and, in
the case of any such default described in this clause (ii), the Trustee receives
a notice of such default of the type referred to in this clause (ii) (a "Payment
Blockage Notice") from the Corporation or the holders of any Designated Senior
Indebtedness. Payments on the Securities may and shall be resumed (a) in the
case of a payment default, upon the date on which such default is cured or
waived in writing by the holders of the applicable Senior Indebtedness and (b)
in case of a nonpayment default, the earlier of the date on which such
nonpayment default is cured or waived in writing by the holders of Designated
Senior Indebtedness or 179 days after the date on which the applicable Payment
Blockage Notice is received by the Trustee, unless the maturity of any
Designated Senior Indebtedness has been accelerated. No new period of payment
blockage may be commenced under clause (ii) above unless and until (i) 360 days
have elapsed since the effectiveness of the immediately prior Payment Blockage
Notice and (ii) all scheduled payments of principal of, premium, if any, and
interest on the Securities that have come due have been paid in full in cash. No
nonpayment default that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice unless such default shall have been waived in
writing or cured for a period of not less than 180 days. If the Corporation
makes any payment to the Trustee or any Holder of any Securities prohibited by
the foregoing, such payment will be required to be held in trust for and paid
over to the holders of Senior Indebtedness (or the representatives thereof).

         Notwithstanding the foregoing, at any time after the 90th day following
the date of deposit of money or Government Obligations pursuant to Section 1304
(provided all other conditions set out in such Section shall have been
satisfied) the funds so deposited and any interest thereon will not be subject
to any rights of holders of Senior Indebtedness including, without limitation,
those arising under this Article.

         For purposes of this Article Fourteen, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Corporation as
reorganized or readjusted, or securities of the Corporation or any other Person
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article with respect to
the Securities to the payment of all Senior Indebtedness which may at the time
be outstanding;



                                       66
<PAGE>   73

provided that (i) the indebtedness or guarantee of indebtedness, as the case may
be, that constitutes Senior Indebtedness is assumed by the Person, if any,
resulting from any such reorganization or readjustment, and (ii) the rights of
the holders of the Senior Indebtedness are not, without the consent of each such
holder adversely affected thereby, altered by such reorganization or
readjustment. The consolidation of the Corporation with, or the merger of the
Corporation into, another Person or the liquidation or dissolution of the
Corporation following the conveyance or transfer of its property as an entirety,
or substantially as an entirety, to another Person upon the terms and conditions
provided for in Article Eight hereof shall not be deemed a dissolution,
winding-up, liquidation or reorganization for the purposes of this Section if
such other Person shall, as part of such consolidation, merger, conveyance or
transfer, comply with the conditions stated in Article Eight hereof.

SECTION 1402.     DISPUTES WITH HOLDERS OF CERTAIN SENIOR INDEBTEDNESS.

         Any failure by the Corporation to make any payment on or perform any
other obligation under Senior Indebtedness, other than any indebtedness incurred
by the Corporation or assumed or guaranteed, directly or indirectly, by the
Corporation for money borrowed (or any deferral, renewal, extension or refunding
thereof) or any indebtedness or obligation as to which the provisions of this
Section shall have been waived by the Corporation in the instrument or
instruments by which the Corporation incurred, assumed, guaranteed or otherwise
created such indebtedness or obligation, shall not be deemed a default or event
of default under Section 1401(b) if (i) the Corporation shall be disputing its
obligation to make such payment or perform such obligation and (ii) either (A)
no final judgment relating to such dispute shall have been issued against the
Corporation which is in full force and effect and is not subject to further
review, including a judgment that has become final by reason of the expiration
of the time within which a party may seek further appeal or review, and (B) in
the event of a judgment that is subject to further review or appeal has been
issued, the Corporation shall in good faith be prosecuting an appeal or other
proceeding for review and a stay of execution shall have been obtained pending
such appeal or review.

SECTION 1403.     SUBROGATION.

         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 obligations of the Corporation which by their express terms are subordinated
to Senior Indebtedness of the Corporation to the same extent as the Securities
are subordinated and which are entitled to like rights of subrogation) to the
rights of the holders of Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Corporation applicable to
the Senior Indebtedness until all amounts owing on the Securities shall be paid
in full, and as between the Corporation, its creditors other than holders of
such Senior Indebtedness and the Holders, no such payment or distribution made
to the holders of Senior Indebtedness by virtue of this Article that otherwise
would have been made to the Holders shall be deemed to be a payment by the
Corporation on account of such Senior Indebtedness, it being understood that the
provisions of



                                       67
<PAGE>   74

this Article are and are intended solely for the purpose of defining the
relative rights of the Holders, on the one hand, and the holders of Senior
Indebtedness, on the other hand.

SECTION 1404.     OBLIGATION OF CORPORATION UNCONDITIONAL.

         Nothing contained in this Article or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as among the Corporation, its
creditors other than the holders of Senior Indebtedness and the Holders, the
obligation of the Corporation, which is absolute and unconditional, to pay to
the Holders the principal of and any premium or interest on the Securities as
and when the same shall become due and payable in accordance with their terms,
or is intended to or shall affect the relative rights of the Holders and
creditors of the Corporation other than the holders of Senior Indebtedness, nor
shall anything herein or therein prevent the Trustee or any Holder from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article of the holders
of Senior Indebtedness in respect of cash, property or securities of the
Corporation received upon the exercise of any such remedy.

         Upon payment or distribution of assets of the Corporation referred to
in this Article, the Trustee and the Holders shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which any such
dissolution, winding-up, liquidation or reorganization proceeding affecting the
affairs of the Corporation is pending or upon a certificate of the trustee in
bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee
or agent or other person making any payment or distribution, delivered to the
Trustee or to the Holders, 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 Corporation, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

         The Trustee shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee or representative on behalf of such holder) to
establish that such notice has been given by a holder of Senior Indebtedness or
a trustee or representative on behalf of any such holder or holders. In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness 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
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 payment to such Person pending judicial determination as to
the right of such Person to receive such payment.

SECTION 1405.     PAYMENTS ON SECURITIES PERMITTED.

         Nothing contained in this Article or elsewhere in this Indenture or in
the Securities shall affect the obligations of the Corporation to make, or
prevent the Corporation from making,



                                       68
<PAGE>   75

payment of the principal of or any premium or interest on the Securities in
accordance with the provisions hereof and thereof, except as otherwise provided
in this Article.

SECTION 1406.     EFFECTUATION OF SUBORDINATION BY TRUSTEE.

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

SECTION 1407.     KNOWLEDGE OF TRUSTEE.

         The Corporation shall give prompt written notice to the Trustee of any
fact known to the Corporation which would prohibit the making of any payment of
moneys to or by the Trustee in respect of the Securities pursuant to the
provisions of this Article. Notwithstanding the provisions of this Article or
any other provisions of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts that would prohibit the making of any
payment of moneys to or by the Trustee, or the taking of any other action by the
Trustee, unless and until the Trustee shall have received written notice thereof
mailed or delivered to the Trustee at its Corporate Trust Office from the
Corporation, any Holder, any paying agent or the holder or representative of any
Senior Indebtedness; provided that if at least two Business Days prior to the
date upon which by the terms hereof any such moneys may become payable for any
purpose (including, without limitation, the payment of the principal or any
premium or interest on any Security) the Trustee shall not have received with
respect to such moneys the notice provided for in this Section, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such moneys and to apply the same to the purpose
for which they were received and shall not be affected by any notice to the
contrary that may be received by it within two Business Days prior to or on or
after such date.

SECTION 1408.     TRUSTEE MAY HOLD SENIOR INDEBTEDNESS.

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

SECTION 1409.     RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS NOT IMPAIRED.

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



                                       69
<PAGE>   76

         With respect to the holders of Senior Indebtedness, (i) the duties and
obligations of the Trustee shall be determined solely by the express provisions
of this Indenture; (ii) the Trustee shall not be liable except for the
performance of such duties and obligations as are specifically set forth in this
Indenture; (iii) no implied covenants or obligations shall be read into this
Indenture against the Trustee; and (iv) the Trustee shall not be deemed to be a
fiduciary as to such holders.

SECTION 1410.     TRUST MONEYS NOT SUBORDINATED.

         Notwithstanding anything contained herein to the contrary, payments
from money or Government Obligations held in trust under Article Four or Article
Thirteen by the Trustee for the payment of principal of and any premium or
interest on the Securities of any series shall not be subordinated to the prior
payment of any Senior Indebtedness of the Corporation or subject to the
restrictions set forth in this Article and none of the Holders shall be
obligated to pay over any such amount to the Corporation or any holder of Senior
Indebtedness or any other creditor of the Corporation.

SECTION 1411.     ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any paying agent other than the Trustee shall have
been appointed by the Corporation and be then acting hereunder, the term
"Trustee" as used in this Article shall in such case (unless the context shall
otherwise require) 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 Sections 1407 and 1408 shall not apply to the Corporation if it
acts as its own paying agent.

SECTION 1412.     TRUSTEE; COMPENSATION NOT PREJUDICED.

         Nothing in this Article shall apply to claims of, or payments to, the
Trustee pursuant to Section 607.

                                  ARTICLE XV.
                           IMMUNITY OF INCORPORATORS,
                      STOCKHOLDERS, OFFICERS AND DIRECTORS

SECTION 1501.     INDENTURE AND SECURITIES SOLELY CORPORATE OBLIGATIONS.

         No recourse for the payment of the principal of or any premium or
interest on any Security, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Corporation in this Indenture or in any supplemental indenture, or in any
Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer or director, as
such, past, present or future, of the Corporation or of any successor
corporation, either directly or through the Corporation or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being

         Re:      $500,000,000 Aggregate Offering Price of Securities
                  of Beckman Coulter, Inc.
                  ---------------------------------------------------


Ladies and Gentlemen:

         At your request, we have examined the registration statement on Form
S-3 (the "Registration Statement") being filed by Beckman Coulter, Inc. (the
"Company") with the Securities and Exchange Commission (the "Commission") under
the Securities Act of 1933, as amended (the "Securities Act"), relating to the
offering from time to time, as set forth in the prospectus contained in the
Registration Statement (the "Prospectus") and as shall be set forth in one or
more supplements to the Prospectus (each, a "Prospectus Supplement"), by the
Company of up to $500,000,000 aggregate offering price (as such amount may be
increased pursuant to a registration statement filed with the Commission under
Rule 462(b) in connection with the Registration Statement) of (i) debt
securities (the "Debt Securities"), (ii) shares of preferred stock, par value
$.01 per share (the "Preferred Stock"), (iii) shares of Preferred Stock
represented by depositary shares (the "Depositary Shares"), (iv) shares of
common stock, par value $.01 per share (the "Common Stock") or (v) warrants to
purchase Debt Securities, Preferred Stock, Depositary Shares or Common Stock
(collectively, the "Warrants"). The Debt Securities, Preferred Stock, Depositary
Shares, Common Stock and Warrants are collectively referred to as the
"Securities." The Registration Statement provides that Debt Securities may be
convertible into shares of Common Stock or Preferred Stock and Preferred Stock
may be convertible into shares of Common Stock.

         The Debt Securities will be issued pursuant to one or more indentures,
the forms of which are attached as exhibits to the Registration Statement, by
and among the Company and a trustee

identified therein (the "Trustee"), as the same may be amended or supplemented
from time to time (each, an "Indenture"). The Depositary Shares will be issued
under one or more deposit agreements (each, a "Deposit Agreement"), by and among
the Company and a financial institution identified therein as the depositary
(each, a "Depositary"). The Company may issue receipts ("Depositary Receipts")
for Depositary Shares, each of which will represent a fractional share of
Preferred Stock represented by Depositary Shares. The Warrants will be issued
under one or more warrant agreements (each, a "Warrant Agreement"), by and among
the Company and a financial institution identified therein as warrant agent
(each, a "Warrant Agent").

         In our capacity as your counsel in connection with such registration,
we are familiar with the proceedings taken and proposed to be taken by the
Company in connection with the authorization and issuance of the Securities and,
for the purposes of this opinion, have assumed such proceedings will be timely
completed in the manner presently proposed and that the terms of each issuance
will otherwise be in compliance with law.

         As such counsel, we have examined such matters of fact and questions of
law considered appropriate for purposes of rendering the opinions expressed
below. In our examination, we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals, and the
conformity to authentic original documents of all documents submitted to us as
copies. We have been furnished with, and with your consent have relied upon,
certificates of officers of the Company with respect to certain factual matters.
In addition, we have obtained and relied upon such certificates and assurances
from public officials as we have deemed necessary

         We are opining herein as to the effect on the subject transaction only
of the federal laws of the United States, the General Corporation Law of the
State of Delaware and the internal laws of the State of New York, and we express
no opinion with respect to the applicability thereto, or the effect thereon, of
the laws of any other jurisdiction or, in the case of Delaware, any other laws
or as to any matters of municipal law or the laws of any local agencies within
any state.

         Subject to the foregoing and the other matters set forth herein, it is
our opinion that, as of the date hereof:

         (1)      When the specific terms of a particular Debt Security have
                  been duly established in accordance with an Indenture and
                  applicable law, any such Debt Security has been duly
                  authenticated by the Trustee and duly executed and delivered
                  on behalf of the Company against payment therefor in
                  accordance with the terms of the Indenture and as contemplated
                  by the Registration Statement and/or the applicable Prospectus
                  Supplement, such Debt Security will constitute a valid and
                  binding obligation of the Company.

         (2)      The Company has the authority pursuant to its Amended and
                  Restated Certificate of Incorporation (the "Certificate") to
                  issue up to 10,000,000 shares of Preferred Stock. When a
                  series of Preferred Stock has been duly established in
                  accordance

                  with the terms of the Company's Certificate and applicable
                  law, and upon adoption by the Board of Directors of the
                  Company of a resolution in form and content as required by
                  applicable law and upon issuance and delivery of and payment
                  of legal consideration in excess of the par value thereof for
                  shares of such series in the manner contemplated by the
                  Registration Statement and/or the applicable Prospectus
                  Supplement and by such resolution, such shares of such series
                  of Preferred Stock will be validly issued, fully paid and
                  nonassessable.

         (3)      When the specific terms of a particular issuance of Depositary
                  Shares have been duly established in accordance with a Deposit
                  Agreement and applicable law, and when the Depositary Receipts
                  in the form contemplated and authorized by the Deposit
                  Agreement have been duly executed and delivered by the
                  Depositary and delivered to and paid for by the purchasers
                  thereof in the manner contemplated by the Registration
                  Statement and/or the applicable Prospectus Supplement, and
                  when all corporate action necessary for the issuance of such
                  Depositary Shares and the underlying Preferred Stock has been
                  taken and the Company has received legal consideration in
                  excess of the par value of the underlying Preferred Stock for
                  the issuance thereof, such Depositary Shares will be validly
                  issued and will entitle the holders thereof to the rights
                  specified in the Depositary Receipts and such Deposit
                  Agreement for such Depositary Receipts.

         (4)      The Company has authority pursuant to its Certificate to issue
                  up to 150,000,000 shares of Common Stock. Upon adoption by the
                  Board of Directors of the Company of a resolution in form and
                  content as required by applicable law and upon issuance and
                  delivery of and payment of legal consideration in excess of
                  the par value thereof for such shares in the manner
                  contemplated by the Registration Statement and/or the
                  applicable Prospectus Supplement and by such resolution, such
                  shares of Common Stock will be validly issued, fully paid and
                  nonassessable.

         (5)      When the specific terms of a particular issuance of Warrants
                  have been duly established by a Warrant Agreement in
                  accordance with applicable law, duly authenticated by the
                  Warrant Agent and duly executed and delivered by the Company
                  against payment therefor in accordance with the terms of the
                  Warrant Agreement and as contemplated by the Registration
                  Statement and/or the applicable Prospectus Supplement, the
                  Warrants will constitute valid and binding obligations of the
                  Company.

         The opinions set forth in clauses 1 and 5 above are subject to the
following exceptions, limitations and qualifications: (i) the effect of
bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or
other similar laws now or hereafter in effect relating to or affecting the
rights or remedies of creditors; (ii) the effect of general principles of
equity, whether enforcement is considered in a proceeding in equity or at law,
and the discretion of the court

before which any proceeding therefor may be brought and (iii) the
unenforceability under certain circumstances under law or court decisions of
provisions providing for the indemnification of or contribution to a party with
respect to a liability where such indemnification or contribution is contrary to
public policy. We express no opinion (i) concerning the enforceability of the
waiver of rights or defenses contained in Section 515 of the Indenture or (ii)
with respect to whether acceleration of Debt Securities may affect the
collectibility of any portion of the stated principal amount thereof which might
be determined to constitute unearned interest thereon.

         To the extent that the obligations of the Company under each Indenture
may be dependent upon such matters, we assume for purposes of this opinion that
each Trustee is duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization; that each Trustee is duly qualified to
engage in the activities contemplated by the Indenture; that each Indenture has
been duly authorized, executed and delivered by the applicable Trustee and
constitutes the legal, valid and binding obligation of such Trustee, enforceable
against such Trustee in accordance with its terms; that each Trustee is in
compliance, generally and with respect to acting as a trustee under the
applicable Indenture, with all applicable laws and regulations; and that each
Trustee has the requisite organizational and legal power and authority to
perform its obligations under the applicable Indenture.

         To the extent that the obligations of the Company under each Deposit
Agreement may be dependent upon such matters, we assume for purposes of this
opinion that the Depositary is duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization; that the Depositary
is duly qualified to engage in the activities contemplated by the Deposit
Agreement; that the Deposit Agreement has been duly authorized, executed and
delivered by the Depositary and constitutes the legal, valid and binding
obligation of the Depositary, enforceable against the Depositary in accordance
with its terms; that the Depositary is in compliance, generally and with respect
to acting as a Depositary under the Deposit Agreement, with all applicable laws
and regulations; and that the Depositary has the requisite organizational and
legal power and authority to perform its obligations under the Deposit
Agreement.

         To the extent that the obligations of the Company under each Warrant
Agreement may be dependent upon such matters, we assume for purposes of this
opinion that the Warrant Agent is duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization; that the Warrant
Agent is duly qualified to engage in the activities contemplated by the Warrant
Agreement; that the Warrant Agreement has been duly authorized, executed and
delivered by the Warrant Agent and constitutes the legal, valid and binding
obligation of the Warrant Agent, enforceable against the Warrant Agent in
accordance with its terms; that the Warrant Agent is in compliance, generally
and with respect to acting as a Warrant Agent under the Warrant Agreement, with
all applicable laws and regulations; and that the Warrant Agent has the
requisite organizational and legal power and authority to perform its
obligations under the Warrant Agreement.

                  A COPY OF THE ARTICLES OF ASSOCIATION OF THE
                              TRUSTEE NOW IN EFFECT

                              AMENDED AND RESTATED
                             ARTICLES OF ASSOCIATION
                                       OF
                  BANK ONE TRUST COMPANY, NATIONAL ASSOCIATION


FIRST. The title of this Association shall be BANK ONE TRUST COMPANY, NATIONAL
ASSOCIATION.

SECOND. The main office of the Association shall be in the City of Columbus,
County of Franklin, State of Ohio.

The business of the Association will be limited to the fiduciary powers and the
support of activities incidental to the exercise of those powers. The
Association will not expand or alter its business beyond that stated in this
article without the prior approval of the Comptroller of the Currency.

THIRD. The Board of Directors of this Association shall consist of not less than
five nor more than twenty-five persons, the exact number to be fixed and
determined from time to time by resolution of a majority of the full Board of
Directors or by resolution of a majority of the shareholders at any annual or
special meeting thereof. Each director shall own common or preferred stock of
the Association, or of a holding company owning the Association, with an
aggregate par, fair market or equity value of not less than $1,000, as of either
(i) the date of purchase, (ii) the date the person became a director, or (iii)
the date of that person's most recent election to the Board of Directors,
whichever is more recent. Any combination of common or preferred stock of the
Association or holding company may be used.

Any vacancy in the Board of Directors may be filled by action of a majority of
the remaining directors between meetings of shareholders. The Board of Directors
may not increase the number of directors between meetings of shareholders to a
number which: (1) exceeds by more than two the number of directors last elected
by shareholders where the number was 15 or less; or (2) exceeds by more than
four the number of directors last elected by shareholders where the number was
16 or more, but in no event shall the number of directors exceed 25.

Terms of directors, including directors selected to fill vacancies, shall expire
at the next regular meeting of shareholders at which directors are elected,
unless the directors resign or are removed from office.

Despite the expiration of a director's term, the director shall continue to
serve until his or her successor is elected and qualifies or until there is a
decrease in the number of directors and his or her position is eliminated.

Honorary or advisory members of the Board of Directors, without voting power or
power of final decision in matters concerning the business of the Association,
may be appointed by resolution of a majority of the full Board of Directors, or
by resolution of shareholders at any annual or special meeting. Honorary or
advisory directors shall not be counted to


<PAGE>   5

determine the number of directors of the Association or the presence of a quorum
in connection with any board action, and shall not be required to own qualifying
shares.

FOURTH. There shall be an annual meeting of the shareholders to elect directors
and transact whatever other business may be brought before the meeting. It shall
be held at the main office or any other convenient place the Board of Directors
may designate, on the day of each year specified therefor in the Bylaws or, if
that day falls on a legal holiday in the state in which the Association is
located, on the next following banking day. If no election is held on the day
fixed or in the event of a legal holiday on the following banking day, an
election may be held on any subsequent day within 60 days of the day fixed, to
be designated by the Board of Directors or, if the directors fail to fix the
day, by shareholders representing two-thirds of the shares issued and
outstanding. In all cases at least 10 days advance notice of the meeting shall
be given to the shareholders by first class mail.

In all elections of directors, the number of votes each common shareholder may
cast will be determined by multiplying the number of shares such shareholder
owns by the number of directors to be elected. Those votes may be cumulated and
cast for a single candidate or may be distributed among two or more candidates
in the manner selected by the shareholder. On all other questions, each common
shareholder shall be entitled to one vote for each share of stock held by such
shareholder. If the issuance of preferred stock with voting rights has been
authorized by a vote of shareholders owning a majority of the common stock of
the association, preferred shareholders will have cumulative voting rights and
will be included within the same class as common shareholders, for purposes of
elections of directors.

A director may resign at any time by delivering written notice to the Board of
Directors, its chairperson, or to the Association, which resignation shall be
effective when the notice is delivered unless the notice specifies a later
effective date.

A director may be removed by shareholders at a meeting called to remove him or
her, when notice of the meeting stating that the purpose or one of the purposes
is to remove him or her is provided, if there is a failure to fulfill one of the
affirmative requirements for qualification, or for cause, provided, however,
that a director may not be removed if the number of votes sufficient to elect
him or her under cumulative voting is voted against his or her removal.

FIFTH. The authorized amount of capital stock of this Association shall be
eighty thousand shares of common stock of the par value of ten dollars ($10.00)
each; but said capital stock may be increased or decreased from time to time,
according to the provisions of the laws of the United States.

No holder of shares of the capital stock of any class of the Association shall
have any preemptive or preferential right of subscription to any shares of any
class of stock of the Association, whether now or hereafter authorized, or to
any obligations convertible into stock of the Association, issued or sold, nor
any right of subscription to any thereof other than such, if any, as the Board
of Directors, in its discretion, may from time to time determine and at such
price as the Board of Directors may from time to time fix. Unless otherwise
specified in the Articles of Association or required by law, (1) all matters
requiring shareholder action, including amendments to the Articles of
Association, must be approved by shareholders owning a majority voting interest
in the outstanding voting stock, and (2) each shareholder shall be entitled to
one vote per share.


<PAGE>   6

Unless otherwise specified in the Articles of Association or required by law,
all shares of voting stock shall be voted together as a class on any matters
requiring shareholder approval. If a proposed amendment would affect two or more
classes or series in the same or a substantially similar way, all the classes or
series so affected must vote together as a single voting group on the proposed
amendment.

Shares of the same class or series may be issued as a dividend on a pro rata
basis and without consideration. Shares of another class or series may be issued
as share dividends in respect of a class or series of stock if approved by a
majority of the votes entitled to be cast by the class or series to be issued
unless there are no outstanding shares of the class or series to be issued.
Unless otherwise provided by the Board of Directors, the record date for
determining shareholders entitled to a share dividend shall be the date the
Board of Directors authorizes the share dividend.

Unless otherwise provided in the Bylaws, the record date for determining
shareholders entitled to notice of and to vote at any meeting is the close of
business on the day before the first notice is mailed or otherwise sent to the
shareholders, provided that in no event may a record date be more than 70 days
before the meeting.

If a shareholder is entitled to fractional shares pursuant to preemptive rights,
a stock dividend, consolidation or merger, reverse stock split or otherwise, the
Association may: (a) issue fractional shares or; (b) in lieu of the issuance of
fractional shares, issue script or warrants entitling the holder to receive a
full share upon surrendering enough script or warrants to equal a full share;
(c) if there is an established and active market in the Association's stock,
make reasonable arrangements to provide the shareholder with an opportunity to
realize a fair price through sale of the fraction, or purchase of the additional
fraction required for a full share; (d) remit the cash equivalent of the
fraction to the shareholder; or (e) sell full shares representing all the
fractions at public auction or to the highest bidder after having solicited and
received sealed bids from at least three licensed stock brokers, and distribute
the proceeds pro rata to shareholders who otherwise would be entitled to the
fractional shares. The holder of a fractional share is entitled to exercise the
rights for shareholder, including the right to vote, to receive dividends, and
to participate in the assets of the Association upon liquidation, in proportion
to the fractional interest. The holder of script or warrants is not entitled to
any of these rights unless the script or warrants explicitly provide for such
rights. The script or warrants may be subject to such additional conditions as:
(1) that the script or warrants will become void if not exchanged for full
shares before a specified date; and (2) that the shares for which the script or
warrants are exchangeable may be sold at the option of the Association and the
proceeds paid to scriptholders.

The Association, at any time and from time to time, may authorize and issue debt
obligations, whether or not subordinated, without the approval of the
shareholders. Obligations classified as debt, whether or not subordinated, which
may be issued by the Association without the approval of shareholders, do not
carry voting rights on any issue, including an increase or decrease in the
aggregate number of the securities, or the exchange or reclassification of all
or part of securities into securities of another class or series.

SIXTH. The Board of Directors shall appoint one of its members president of this
Association, and one of its members chairperson of the board and shall have the
power to appoint one or more vice presidents, a secretary who shall keep minutes
of the directors' and shareholders' meetings and be responsible for
authenticating the records of the Association, and such other officers and
employees as may be required to transact the



<PAGE>   7

business of this Association. A duly appointed officer may appoint one or more
officers or assistant officers if authorized by the Board of Directors in
accordance with the Bylaws. The Board of Directors shall have the power to:

(1)      Define the duties of the officers, employees, and agents of the
         Association.

(2)      Delegate the performance of its duties, but not the responsibility for
         its duties, to the officers, employees, and agents of the Association.

(3)      Fix the compensation and enter into employment contracts with its
         officers and employees upon reasonable terms and conditions consistent
         with applicable law.

(5)      Require bonds from officers and employees and to fix the penalty
         thereof.

         committees of the board.

(7)      Regulate the manner in which any increase or decrease of the capital of
         the Association shall be made, provided that nothing herein shall
         restrict the power of shareholders to increase or decrease the capital
         of the association in accordance with law, and nothing shall raise or
         lower from two-thirds the percentage for shareholder approval to
         increase or reduce the capital.

(8)      Manage and administer the business and affairs of the Association.

(9)      Adopt initial Bylaws, not inconsistent with law or the Articles of
         Association, for managing the business and regulating the affairs of

(10)     Amend or repeal Bylaws, except to the extent that the Articles of
         Association reserve this power in whole or in part to shareholders.

(11)     Make contracts.

(12)     Generally perform all acts that are legal for a Board of Directors to
         perform.

SEVENTH. The Board of Directors shall have the power to change the location of
the main office of this Association to any other place within the limits of the
City of Columbus, State of Ohio, without the approval of the shareholders; and
shall have the power to change the location of the main office of this
Association to any other place outside the limits of the City of Columbus, State
of Ohio, but not more than thirty miles beyond such limits, with the affirmative
vote of shareholders owning two-thirds of the stock of the Association, subject
to receipt of a certificate of approval from the Comptroller of the Currency.
The Board of Directors shall have the power to establish or change the location
of any branch or branches of the Association to any other location permitted
under applicable law without the approval of the shareholders, subject to
approval by the Office of the Comptroller of the Currency. The Board of
Directors shall have the power to establish or change the location of any
nonbranch office or facility of the Association without the approval of the
shareholders.

<PAGE>   8

NINTH. The Board of Directors of this Association, or any shareholders owning,
in the aggregate, not less than 20 percent of the stock of this Association, may
call a special meeting of shareholders at any time. Unless otherwise provided by
the Bylaws or the laws of the United States, or waived by shareholders, a notice
of the time, place, and purpose of every annual and special meeting of the
shareholders shall be given by first-class mail, postage prepaid, mailed at
least 10, and no more than 60, days prior to the date of the meeting to each
shareholder of record at his/her address as shown upon the books of this
Association. Unless otherwise provided by the Bylaws, any action requiring
approval of shareholders must be effected at a duly called annual or special
meeting.

TENTH.  The Association shall provide indemnification as set forth below:

Every person who is or was a Director, officer or employee of the Association or
of any other corporation which he served as a Director, officer or employee at
the request of the Association as part of his regularly assigned duties may be
indemnified by the Association in accordance with the provisions of this Article
against all liability (including, without limitation, judgments, fines,
penalties, and settlements) and all reasonable expenses (including, without
limitation, attorneys' fees and investigative expenses) that may be incurred or
paid by him in connection with any claim, action, suit or proceeding, whether
civil, criminal or administrative (all referred to hereafter in this Article as
"Claims") or in connection with any appeal relating thereto in which he may
become involved as a party or otherwise or with which he may be threatened by
reason of his being or having been a Director, officer or employee of the
Association or such other corporation, or by reason of any action taken or
omitted by him in his capacity as such Director, officer or employee, whether or
not he continues to be such at the time such liability or expenses are incurred;
provided that nothing contained in this Article shall be construed to permit
indemnification of any such person who is adjudged guilty of, or liable for,
willful misconduct, gross neglect of duty or criminal acts, unless, at the time
such indemnification is sought, such indemnification in such instance is
permissible under applicable law and regulations, including published rulings of
the Comptroller of the Currency or other appropriate supervisory or regulatory
authority; and provided further that there shall be no indemnification of
Directors, officers, or employees against expenses, penalties, or other payments
incurred in an administrative proceeding or action instituted by an appropriate
regulatory agency which proceeding or action results in a final order assessing
civil money penalties or requiring affirmative action by an individual or
individuals in the form of payments to the Association.

Every person who may be indemnified under the provisions of this Article and who
has been wholly successful on the merits with respect to any Claim shall be
entitled to indemnification as of right. Except as provided in the preceding
sentence, any indemnification under this Article shall be at the sole discretion
of the Board of Directors and shall be made only if the Board of Directors or
the Executive Committee acting by a quorum consisting of Directors who are not
parties to such Claim shall find or if independent legal counsel (who may be the
regular counsel of the Association) selected by the Board of Directors or
Executive Committee whether or not a disinterested quorum exists shall render
their opinion that in view of all of the circumstances then surrounding the
Claim, such indemnification is equitable and in the best interests of the
Association. Among the circumstances to be taken into consideration in arriving
at such a finding or opinion is the existence or non-existence of a contract of
insurance or indemnity under which the Association would be wholly or partially
reimbursed for such indemnification, but the existence or non-existence of such
insurance is not the sole circumstance to be considered nor shall it be wholly
determinative of whether such indemnification shall be


<PAGE>   9

made. In addition to such finding or opinion, no indemnification under this
Article shall be made unless the Board of Directors or the Executive Committee
acting by a quorum consisting of Directors who are not parties to such Claim
shall find or if independent legal counsel (who may be the regular counsel of
the Association) selected by the Board of Directors or Executive Committee
whether or not a disinterested quorum exists shall render their opinion that the
Directors, officer or employee acted in good faith in what he reasonably
believed to be the best interests of the Association or such other corporation
and further in the case of any criminal action or proceeding, that the Director,
officer or employee reasonably believed his conduct to be lawful. Determination
of any Claim by judgment adverse to a Director, officer or employee by
settlement with or without Court approval or conviction upon a plea of guilty or
of nolo contendere or its equivalent shall not create a presumption that a
Director, officer or employee failed to meet the standards of conduct set forth
in this Article. Expenses incurred with respect to any Claim may be advanced by
the Association prior to the final disposition thereof upon receipt of an
undertaking satisfactory to the Association by or on behalf of the recipient to
repay such amount unless it is ultimately determined that he is entitled to
indemnification under this Article.

The rights of indemnification provided in this Article shall be in addition to
any rights to which any Director, officer or employee may otherwise be entitled
by contract or as a matter of law. Every person who shall act as a Director,
officer or employee of this Association shall be conclusively presumed to be
doing so in reliance upon the right of indemnification provided for in this
Article.

ELEVENTH. These Articles of Association may be amended at any regular or special
meeting of the shareholders by the affirmative vote of the holders of a majority
of the stock of this Association, unless the vote of the holders of a greater
amount of stock is required by law, and in that case by the vote of the holders
of such greater amount. The Association's Board of Directors may propose one or
more amendments to the Articles of Association for submission to the
shareholders.

<PAGE>   12

SECTION 1.01. ANNUAL MEETING. The regular annual meeting of the shareholders of
the Bank for the election of Directors and for the transaction of such business
as may properly come before the meeting shall be held at its main office, or
other convenient place duly authorized by the Board of Directors, on the same
day upon which any regular or special Board meeting is held from and including
the first Monday of January to, and including, the fourth Monday of February of
each year, or on the next succeeding banking day, if the day fixed falls on a
legal holiday. If from any cause, an election of Directors is not made on the
day fixed for the regular meeting of the shareholders or, in the event of a
legal holiday, on the next succeeding banking day, the Board of Directors shall
order the election to be held on some subsequent day, as soon thereafter as
practicable, according to the provisions of law; and notice thereof shall be
given in the manner herein provided for the annual meeting. Notice of such
annual meeting shall be given by or under the direction of the Secretary, or
such other officer as may be designated by the Chief Executive Officer, by

their respective addresses as shown upon the books of the Bank mailed not less
than ten days prior to the date fixed for such meeting.

SECTION 1.02. SPECIAL MEETINGS. A special meeting of the shareholders of the

of Directors, stating the time, place and purpose of the meeting, shall be given

to all shareholders of record of the Bank at their respective addresses as shown
upon the books of the Bank mailed not less than ten days prior to the date fixed

proceedings recorded in the manner prescribed in these By-Laws for annual
meetings of shareholders.

SECTION 1.03. SECRETARY OF MEETING OF SHAREHOLDERS. The Board of Directors may
designate a person to be the secretary of the meeting of shareholders. In the
absence of a presiding officer, as designated by these By-Laws, the Board of
Directors may designate a person to act as the presiding officer. In the event
the Board of Directors fails to designate a person to preside at a meeting of
shareholders and a secretary of such meeting, the shareholders present or
represented shall elect a person to preside and a person to serve as secretary
of the meeting. The secretary of the meeting of shareholders shall cause the
returns made by the judges of election and other proceedings to be recorded in
the minute books of the Bank. The presiding officer shall notify the
Directors-elect of their election and to meet forthwith for the organization of
the new Board of Directors. The minutes of the meeting shall be signed by the

same, and who shall, after the election has been held, notify, in writing over
their signatures, the secretary of the meeting of shareholders of the result
thereof and the names of the Directors elected; provided, however, that upon
failure for any reason of any judge or judges of election, so appointed by the
Directors, to serve, the presiding officer of the meeting shall appoint other
shareholders or their proxies to fill the vacancies. The judges of election, at
the request of the chairman of the meeting, shall act as tellers of any other


<PAGE>   13

vote by ballot taken at such meeting, and shall notify, in writing over their
signature, the secretary of the Board of Directors of the result thereof.

SECTION 1.05. PROXIES. In all elections of Directors, each shareholder of
record, who is qualified to vote under the provisions of Federal Law, shall have
the right to vote the number of shares of record in such shareholder's name for
as many persons as there are Directors to be elected, or to cumulate such shares
as provided by Federal Law. In deciding all other questions at meetings of
shareholders, each shareholder shall be entitled to one vote on each share of
stock of record in such shareholder's name. Shareholders may vote by proxy duly
authorized in writing. All proxies used at the annual meeting shall be secured
for that meeting only, or any adjournment thereof, and shall be dated, if not
dated by the shareholder, as of the date of the receipt thereof. No officer or
employee of this Bank may act as proxy.

SECTION 1.06. QUORUM. Holders of record of a majority of the shares of the
capital stock of the Bank, eligible to be voted, present either in person or by
proxy, shall constitute a quorum for the transaction of business at any meeting
of shareholders, but shareholders present at any meeting and constituting less
than a quorum may, without further notice, adjourn the meeting from time to time
until a quorum is obtained. A majority of the votes cast shall decide every
question or matter submitted to the shareholders at any meeting, unless
otherwise provided by law or by the Articles of Association.

powers of office until such Director has taken the oath of such office.

SECTION 2.02. VACANCIES. Directors of the Bank shall hold office for one year or
until their successors are elected and qualified. Any vacancy in the Board shall
be filled by appointment of the remaining Directors, and any Director so
appointed shall hold office until the next election.

SECTION 2.03. ORGANIZATION MEETING. The Directors elected by the shareholders
shall meet for organization of the new Board of Directors at the time and place
fixed by the presiding officer of the annual meeting. If at the time fixed for
such meeting there is no quorum present, the Directors in attendance may adjourn
from time to time until a quorum is obtained. A majority of the number of
Directors elected by the shareholders shall constitute a quorum for the
transaction of business.

SECTION 2.04. REGULAR MEETINGS. The regular meetings of the Board of Directors
shall be held at such date, time and place as the Board may previously
designate, or should the Board fail to so designate, at such date, time and
place as the Chairman of the Board, Chief Executive Officer, or President may
fix. Whenever a quorum is not present, the Directors in attendance shall adjourn
the meeting to a time not later than the date fixed by the By-Laws for the next
succeeding regular meeting of the Board. Members of the Board of Directors may
participate in such meetings through use of conference telephone or


<PAGE>   14

similar communications equipment, so long as all members participating in such
meetings can hear one another.

SECTION 2.05. SPECIAL MEETINGS. Special meetings of the Board of Directors shall
be held at the call of the Chairman of the Board, Chief Executive Officer, or
President, or at the request of two or more Directors. Any special meeting may
be held at such place and at such time as may be fixed in the call. Written or
oral notice shall be given to each Director not later than the day next
preceding the day on which the special meeting is to be held, which notice may
be waived in writing. The presence of a Director at any meeting of the Board of
Directors shall be deemed a waiver of notice thereof by such Director. Whenever
a quorum is not present, the Directors in attendance shall adjourn the special
meeting from day to day until a quorum is obtained. Members of the Board of
Directors may participate in such meetings through use of conference telephone
or similar communications equipment, so long as all members participating in
such meetings can hear one another.

SECTION 2.06. QUORUM. A majority of the Directors shall constitute a quorum at
any meeting, except when otherwise provided by law; but a lesser number may
adjourn any meeting, from time-to-time, and the meeting may be held, as
adjourned, without further notice. When, however, less than a quorum as herein
defined, but at least one-third and not less than two of the authorized number
of Directors are present at a meeting of the Directors, business of the Bank may
be transacted and matters before the Board approved or disapproved by the
unanimous vote of the Directors present.

SECTION 2.07. COMPENSATION. Each member of the Board of Directors shall receive
such fees for attendance at Board and Board committee meetings and such fees for
service as a Director, irrespective of meeting attendance, as from time to time
are fixed by resolution of the Board; provided, however, that payment hereunder
shall not be made to a Director for meetings attended and/or Board service which
are not for the Bank's sole benefit and which are concurrent and duplicative
with meetings attended or Board service for an affiliate of the Bank for which
the Director receives payment; and provided further that fees hereunder shall
not be paid in the case of any Director in the regular employment of the Bank or
of one of its affiliates. Each member of the Board of Directors, whether or not
such Director is in the regular employment of the Bank or of one of its
affiliates, shall be reimbursed for travel expenses incident to attendance at
Board and Board committee meetings.

SECTION 2.08. EXECUTIVE COMMITTEE. There may be a standing committee of the
Board of Directors known as the Executive Committee which shall possess and
exercise, when the Board is not in session, all the powers of the Board that may
lawfully be delegated. The Executive Committee shall consist of at least three
Board members, one of whom shall be the Chairman of the Board, Chief Executive
Officer or the President. The other members of the Executive Committee shall be
appointed by the Chairman of the Board, the Chief Executive Officer, or the
President, with the approval of the Board, and who shall continue as members of
the Executive Committee until their successors are appointed, provided, however,
that any member of the Executive Committee may be removed by the Board upon a
majority vote thereof at any regular or special meeting of the Board. The
Chairman, Chief Executive Officer, or President shall fill any vacancy in the
Executive Committee by the appointment of another Director, subject to the
approval of


<PAGE>   15

the Board of Directors. The Executive Committee shall meet at the call of the
Chairman, Chief Executive Officer, or President or any two members thereof at
such time or times and place as may be designated. In the event of the absence
of any member or members of the Executive Committee, the presiding member may
appoint a member or members of the Board to fill the place or places of such
absent member or members to serve during such absence. Two members of the
Executive Committee shall constitute a quorum. When neither the Chairman of the
Board, the Chief Executive Officer, nor President are present, the Executive
Committee shall appoint a presiding officer. The Executive Committee shall
report its proceedings and the action taken by it to the Board of Directors.

SECTION 2.09. OTHER COMMITTEES. The Board of Directors may appoint such special
committees from time to time as are in its judgment necessary in the interest of
the Bank.

own number shall hold office from the date of their election as officers until

of their duties at any time by action of the Board of Directors, in which event
all the powers incident to their office shall immediately terminate. The
Chairman of the Board, Chief Executive Officer, or the President shall preside
at all meetings of shareholders and meetings of the Board of Directors.

(b) The management staff of the Bank shall include officers elected by the
Board, officers appointed by the Chairman of the Board, the Chief Executive

Chief Financial Officer, and such other persons in the employment of the Bank

office of Chairman of the Board, Chief Executive Officer and/or President and at
the same time also hold the office of Secretary.

the Board, all officers and employees, whether elected or appointed, shall hold

Financial Officer may appoint persons other than officers who are in employment
of the Bank to serve in management positions and in connection therewith, the
appointing officer may assign such title, salary, responsibilities and functions

Director, any Managing Director, or the Chief Financial Officer as provided in
this and other sections of these By-Laws.

(e) The Senior Managing Directors and the Managing Directors of the Bank shall

applicable law and regulations. Each Senior Managing Director and Managing
Director shall perform all duties incident to his or her office and such other
and further duties, as may from time to time be required by the Chief Executive
Officer, the President, the Board of Directors, or the shareholders. The
specification of authority in these By-Laws wherever and to whomever granted
shall not be construed to limit in any manner the general powers of delegation
granted to a Senior Managing Director or a Managing Director in conducting the
business of the Bank. In the absence of a Senior Managing Director or a Managing
Director, such officer as is designated by the Senior Managing Director or the
Managing Director shall be vested with all the powers and perform all the duties
of the Senior Managing Director or the Managing Director as defined by these

                          STOCKS AND STOCK CERTIFICATES


SECTION 4.01. STOCK CERTIFICATES. The shares of stock of the Bank shall be
evidenced by certificates which shall bear the signature of the Chairman of the
Board, the Chief Executive Officer, or the President (which signature may be
engraved, printed or impressed), and shall be signed manually by the Secretary,
or any other officer appointed by the Chief Executive Officer for that purpose.
In case any such officer who has signed or whose facsimile signature has been
placed upon such certificate shall have ceased to be such officer before such
certificate is issued, it may be issued by the Bank with the same effect as if
such officer had not ceased to be such at the time of its issue. Each such
certificate shall bear the corporate seal of the Bank, shall recite on its face
that stock represented thereby is transferable only upon the books of the Bank
when properly endorsed and shall recite such other information as is required by
law and deemed appropriate by the Board. The corporate seal may be facsimile
engraved or printed.

SECTION 4.02. STOCK ISSUE AND TRANSFER. The shares of stock of the Bank shall be
transferable only upon the stock transfer books of the Bank and, except as
hereinafter provided, no transfer shall be made or new certificates issued
except upon the surrender for cancellation of the certificate or certificates
previously issued therefor. In the case of the loss, theft, or destruction of
any certificate, a new certificate may be issued in place of such certificate
upon the furnishing of an affidavit setting forth the circumstances of such
loss, theft, or destruction and indemnity satisfactory to the Chairman of the
Board, the Chief Executive Officer, or the President. The Board of Directors or
the Chairman of the Board, Chief Executive Officer, or the President may
authorize the issuance of a new certificate therefor without the furnishing of
indemnity. Stock transfer books, in which all transfers of stock shall be
recorded, shall be provided. The stock transfer books may be closed for a
reasonable period and under such conditions as the Board of Directors may at any
time determine, for any meeting of shareholders, the payment of dividends or any
other lawful purpose. In lieu of closing the transfer books, the Board of
Directors may, in its discretion, fix a record date and hour constituting a
reasonable period prior to the day designated for the holding of any meeting of
the shareholders or the day appointed for the payment of any dividend, or for
any other purpose at the time as of which shareholders entitled to notice of and
to vote at any such meeting or to receive such dividend or to be treated as
shareholders for such other purpose shall be determined, and only shareholders
of record at such time shall be entitled to notice of or to vote at such meeting
or to receive such dividends or to be treated as shareholders for such other
purpose.

expanding the powers of the Bank, without the prior approval of the Comptroller
of the Currency.

of a majority of the Directors.
