                                  COMMON STOCK    


                         ---------------------------


    USA Waste Services, Inc. ("USA Waste" or the "Company") may offer and sell
from time to time, in one or more series, its unsecured debt securities
consisting of notes, debentures or other evidences of indebtedness (the "Debt

its common stock, par value $.01 per share (the "Common Stock").  The aggregate
initial offering prices of the Debt Securities and the Common Stock offered by
the Company hereby (the "Securities") will not exceed $850,000,000 or, if
applicable, the equivalent thereof in any other currency or currency unit.  The
Securities will be offered in amounts, at prices and on terms to be determined
in light of market conditions at the time of sale and set forth in a supplement
to this Prospectus (a "Prospectus Supplement").

    If the offering and sale of Securities in respect of which this Prospectus
is being delivered includes a series of Debt Securities, then the terms of such
series of Debt Securities, including, where applicable, the specific
designation, aggregate principal amount, authorized denominations, ranking as
senior or subordinated Debt Securities, maturity, interest rate or rates (or
method of determining the same) and time or times of payment of any interest,
any terms for optional or mandatory redemption, which may include redemption at
the option of holders upon the occurrence of certain events, conversion into
Common Stock, or payment of additional amounts or any sinking fund provisions,
any initial public offering price, the proceeds to the Company and any other
specific terms in connection with the offering and sale of such series of Debt
Securities will be set forth in a Prospectus Supplement.  As used herein, Debt
Securities shall include securities denominated in United States dollars or, at
the option of the Company if so specified in an applicable Prospectus
Supplement, in any other currency or currency unit, or in amounts determined by
reference to an index.

    The Securities may be sold directly by the Company to investors, through
agents designated from time to time or to or through underwriters or dealers.
See "Plan of Distribution."  If any agents of the Company or any underwriters
are involved in the sale of any Securities in respect of which this Prospectus
is being delivered, the names of such agents or underwriters and any applicable
commissions or discounts will be set forth in a Prospectus Supplement.  The net
proceeds to the Company from such sale also will be set forth in a Prospectus
Supplement.  See "Use of Proceeds."

    Debt Securities may be issued in registered form or bearer form with or
without interest coupons attached, or both.  In addition, all or a portion of
the Debt Securities of a series may be issuable in temporary or permanent
global form.  Debt Securities in bearer form are offered only to non-United
States persons and to offices located outside the United States of certain
United States financial institutions.

                              ------------------

    The Common Stock is traded on the New York Stock Exchange under the symbol
"UW." Any Common Stock sold pursuant to a Prospectus Supplement will be listed
on such exchange, subject to official notice of issuance.

                              ------------------

   THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
      AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS
        THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
           COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
                PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY
                            IS A CRIMINAL OFFENSE.

                      RATIOS OF EARNINGS TO FIXED CHARGES

    The following table sets forth the Company's consolidated ratios of
earnings to fixed charges for the periods as shown.

</TABLE>

    The Company's consolidated ratios of earnings to fixed charges were 
computed by dividing earnings by fixed charges.  For this purpose, earnings are
the sum of income (loss) from continuing operations, taxes, and fixed charges,
excluding capitalized interest. Fixed charges are interest, whether expensed or
capitalized, amortization of debt expense and discount on premium relating to
indebtedness, whether expensed or capitalized, and such portion of rental
expense that can be demonstrated to be representative of the interest factor in
the particular case. For the nine months ended September 30, 1996 and the years
ended December 31, 1994, 1992, and 1991, earnings are insufficient to cover
fixed charges as evidenced by a less than one-to-one coverage ratio as shown
above. Additional earnings of $12,022,000, $17,855,000, $78,473,000, and
$27,827,000 were necessary for the nine months ended September 30, 1996 and the
years ended December 31, 1994, 1992, and 1991, respectively, to provide a
one-to-one coverage ratio.  Except for the year ended December 31, 1991,
nonrecurring costs, as discussed below, caused the less than one-to-one coverage
in each of these periods.

    The following table sets forth the Company's consolidated ratios of
earnings to fixed charges for the periods shown, on a pro forma basis excluding
nonrecurring items.

</TABLE>

    Nonrecurring items for the nine months ended September 30, 1996, represent
merger costs, primarily related to mergers with Sanifill, Inc. in August 1996
and Western Waste Industries ("Western") in May 1996, and unusual items,
primarily related to operating losses and estimated losses associated with the
disposition of certain non-core business assets.  Nonrecurring items in 1995
primarily represent merger costs related to the merger with Chambers
Development Company, Inc. ("Chambers") in June 1995 and nonrecurring interest
related to extension fees and other charges associated with the refinancing of
Chambers pre-merger debt.  Nonrecurring items in 1994 primarily represent
shareholder litigation costs incurred in connection with a settled class action
of consolidated suits on similar claims alleging federal securities violations
against Chambers, certain of its officers and directors, its former auditors,
and the underwriters of its securities.  Nonrecurring items in 1992 primarily
represent various restructuring charges and charges to asset reserves by Western
and Chambers.  Nonrecurring items in 1993 and 1991 were not material.

<PAGE>   6
                         DESCRIPTION OF DEBT SECURITIES

    The Debt Securities will constitute either senior debt of the Company
("Senior Debt Securities"), or subordinated debt of the Company ("Subordinated
Debt Securities").  Debt Securities may be issued from time to time under one
or more indentures, each dated as of a date on or prior to the issuance of the
Debt Securities to which it relates.  Senior Debt Securities and Subordinated
Debt Securities may be issued pursuant to separate indentures (respectively, a
"Senior Debt Indenture" and a "Subordinated Debt Indenture"), in each case
between the Company and a trustee (a "Trustee"), which may be the same Trustee,
and in the form that has been filed as an exhibit to the Registration Statement
of which this Prospectus is a part, subject to such amendments or supplements
as may be adopted form time to time.  The Senior Debt Indenture and the
Subordinated Debt Indenture, as amended or supplemented from time to time, are
sometimes hereinafter referred to individually as an "Indenture" and
collectively as the "Indentures."  The following summaries of anticipated
provisions of the Indentures and the Debt Securities do not purport to be
complete and such summaries are subject to the detailed provisions of the
applicable Indenture to which reference is hereby made for a full description
of such provisions, including the definition of certain terms used herein.
Section references in parentheses below are to sections in both Indentures
unless otherwise indicated.  Wherever particular sections or defined terms of
the applicable Indenture are referred to, such sections or defined terms are
incorporated herein by reference as part of the statement made, and the
statement is qualified in its entirety by such reference.  The Indentures are
substantially identical, except for certain covenants of the Company and
provisions relating to subordination and conversion.

    The Debt Securities may be issued from time to time in one or more series.
The following description of the Debt Securities sets forth certain general
terms and provisions of the Debt Securities of all series.  The particular
terms of each series of Debt Securities offered by any Prospectus Supplement
(the "Offered Debt Securities") will be described therein.

PROVISIONS APPLICABLE TO BOTH SENIOR AND SUBORDINATED DEBT SECURITIES

    General.  The Debt Securities will be unsecured senior or subordinated
obligations of the Company and may be issued from time to time in one or more
series.  The Indentures do not limit the amount of Debt Securities, debentures,
notes or other types of indebtedness that may be issued by the Company or any
of its subsidiaries nor do they restrict transactions between the Company and
its affiliates or the payment of dividends or other distributions by the
Company to its stockholders.  The rights of the Company's creditors, including
holders of Debt Securities, will be limited to the assets of the Company and
will not be an obligation of any of its Subsidiaries.  In addition, other than
as may be set forth in any Prospectus Supplement, the Indentures do not and the
Debt Securities will not contain any covenants or other provisions that are
intended to afford holders of the Debt Securities special protection in the
event of either a change of control of the Company or a highly leveraged
transaction by the Company.

    Reference is made to the Prospectus Supplement for the following terms of
and information relating to the Offered Debt Securities (to the extent such
terms are applicable to such Offered Debt Securities):  (i) the title of the
Offered Debt Securities; (ii) classification as either Senior Debt Securities
or Subordinated Debt Securities; (iii) whether the Offered Debt Securities that
constitute Subordinated Debt Securities are convertible into Common Stock and,
if so, the terms and conditions upon which such conversion will be effected
including the initial conversion price or conversion rate and any adjustments
thereto in addition to or different from those described herein, the conversion
period and other conversion provisions in addition to or in lieu of those
described herein; (iv) any limit on the aggregate principal amount of the
Offered Debt Securities; (v) whether the Offered Debt Securities are to be
issuable as Registered Securities or Bearer





                                       5
<PAGE>   7
Securities or both, whether any of the Offered Debt Securities are to be
issuable initially in temporary global form and whether any of the Offered Debt
Securities are to be in permanent global form; (vi) the price or prices
(expressed as a percentage of the aggregate principal amount thereof) at which
the Offered Debt Securities will be issued; (vii) the date or dates on which
the Offered Debt Securities will mature; (viii) the rate or rates per annum (or
the method by which such will be determined) at which the Offered Debt
Securities will bear interest, if any, and the date from which any such
interest will accrue; (ix) the Interest Payment Data on which any such interest
on the Offered Debt Securities will be payable, the Regular Record Date for any
interest payable on any Offered Debt Securities which are Registered Securities
on any Interest Payment Date and the extent to which, or the manner in which,
any interest payable on a temporary global Offered Debt Security on an Interest
Payment Date will be paid; (x) any mandatory or optional sinking fund or
analogous provisions; (xi) each office or agency where, subject to the terms of
the Indentures as described below under "Payment and Paying Agents," the
principal of and any premium and interest on the Offered Debt Securities will
be payable and each office or agency where, subject to the terms of the
Indentures as described below under "Form, Exchange, Registration and
Transfer," the Offered Debt Securities may be presented for registration of
transfer or exchange; (xii) the right of the Company to redeem the Offered Debt
Securities at its option and the period or periods, if any, within which and
the price or prices at which the Offered Debt Securities may, pursuant to any
optional or mandatory redemption provisions, be redeemed, in whole or in part,
and the other detailed terms and provisions of any such optional or mandatory
redemption; (xiii) the denominations in which any Offered Debt Securities which
are Registered Securities will be issuable, if other than denominations of
$1,000 and any integral multiple thereof, and the denomination or denominations
in which any Offered Debt Securities which are Bearer Securities will be
issuable, if other than the denomination of $5,000; (xiv) the currency or
currencies (including composite currencies) in which payment of principal of
and any premium and interest on the Offered Debt Securities is payable; (xv)
any index used to determine the amount of payments of principal of and any
premium and interest on the Offered Debt Securities; (xvi) information with
respect to book-entry procedures, if any; and (xvii) any other terms of the
Offered Debt Securities not inconsistent with the provisions of the Indentures.
(Section 301)  Any such Prospectus Supplement will also describe any special
provisions for the payment of additional amounts with respect to the Offered
Debt Securities.

    Debt Securities may be issued as Original Issue Discount Securities.  An
Original Issue Discount Security is a Debt Security, including any Zero-Coupon
Security, which is issued at a price lower than the amount payable upon the
Stated Maturity thereof and which provides that upon redemption or acceleration
of the maturity thereof an amount less than the amount payable upon the Stated
Maturity thereof and determined in accordance with the terms of such Debt
Security shall become due and payable.  Special United States federal income
tax considerations applicable to Debt Securities issued at an original issue
discount, including Original Issue Discount Securities, and special United
States tax considerations and other terms and restrictions applicable to any
Debt Securities which are issued in bearer form, offered exclusively to United
States Aliens or denominated in other than United States dollars, will be set
forth in a Prospectus Supplement relating thereto.

    Form, Exchange, Registration and Transfer.  Debt Securities of a series may
be issuable in definitive form solely as Registered Securities, solely as
Bearer Securities or as both Registered Securities and Bearer Securities.
Unless otherwise indicated in an applicable Prospectus Supplement, Bearer
Securities will have interest coupons attached.  (Section 201)  The Indentures
also provide that Debt Securities of a series may be issuable in temporary or
permanent global form.  (Section 201)

    Registered Securities of any series will be exchangeable for other
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor.  In addition, if Debt





                                       6
<PAGE>   8
Securities of any series are issuable as both Registered Securities and Bearer
Securities, at the option of the Holder, and subject to the terms of the
applicable Indenture, Bearer Securities (with all unmatured coupons, except as
provided below, and all matured coupons in default) of such series will be
exchangeable for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor.  Bearer
Securities surrendered in exchange for Registered Securities between a Regular
Record Date or a Special Record Date and the relevant date for payment of
interest shall be surrendered without the coupon relating to such date for
payment of interest, and interest accrued as of such date will not be payable
in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such coupon when due in
accordance with the terms of the applicable Indenture. Bearer Securities will
not be issued in exchange for Registered Securities.  (Section 305)

    Debt Securities may be presented for exchange as provided above, and
Registered Securities may be presented for registration of transfer (with the
form of transfer endorsed thereon duly executed), at the office of the Security
Registrar or at the office of any transfer agent designated by the Company for
such purpose with respect to any series of Debt Securities and referred to in
an applicable Prospectus Supplement, without service charge and upon payment of
any taxes and other governmental charges as described in the Indentures.  Such
transfer or exchange will be effected upon the Security Registrar or such
transfer agent, as the case may be, being satisfied with the documents of title
and identity of the person making the request.  The Company will serve
initially as Security Registrar.  (Section 305)  If a Prospectus Supplement
refers to any transfer agents (in addition to the Security Registrar) initially
designated by the Company with respect to any series of Debt Securities, the
Company may at any time rescind the designation of any such transfer agent or
approve a change in the location through which any such transfer agent acts,
except that, if Debt Securities of a series are issuable solely as Registered
Securities, the Company will be required to maintain a transfer agent in each
Place of Payment for such series and, if Debt Securities of a series are also
issuable as Bearer Securities, the Company will be required to maintain (in
addition to the Security Registrar) a transfer agent in a Place of Payment for
such series located outside the United States.  The Company may at any time
designate additional transfer agents with respect to any series of Debt
Securities.  (Section 1002)

    In the event of any redemption in part, the Company shall not be required
to (i) issue, register the transfer of or exchange Debt Securities of any
series during a period beginning at the opening of business 15 days prior to
the selection of Debt Securities of that series for redemption and ending on
the close of business on (A) if Debt Securities of the series are issuable only
as Registered Securities, the day of mailing of the relevant notice of
redemption and (B) if Debt Securities of the series are issuable as Bearer
Securities, the date of the first publication of the relevant notice of
redemption or, if Securities of the series are also issuable as Registered
Securities and there is no publication, the mailing of the relevant notice of
redemption; (ii) register the transfer of or exchange any Registered Security,
or portion thereof, called for redemption, except the unredeemed portion of any
Registered Security being redeemed in part, or (iii) exchange any Bearer
Security called for redemption, except to exchange such Bearer Security for a
Registered Security of that series and like tenor which is immediately
surrendered for redemption.  (Section 305)

    Payment and Paying Agents.  Unless otherwise indicated in an applicable
Prospectus Supplement, payment of principal of and any premium and interest on
Bearer Securities will be payable, subject to any applicable laws and
regulations, at the offices of such Paying Agents outside the United States as
the Company may designate from time to time, in the manner indicated in such
Prospectus Supplement.  (Section 1002)  Unless otherwise indicated in an
applicable Prospectus Supplement, payment of interest on Bearer Securities on
any Interest Payment Date will be made only against surrender to the Paying
Agent of the coupon relating to such Interest Payment Date.  (Section 1001)  No
payment with respect to any Bearer Security will be made at any office or
agency of the Company in the United States or by check mailed to any address in
the United





                                       7
<PAGE>   9
States or by transfer to any account maintained with a bank located in the
United States.  Notwithstanding the foregoing, payments of principal of and any
premium and interest on Bearer Securities denominated and payable in U.S.
dollars will be made at the office of the Company's Paying Agent in the Borough
of Manhattan.  The City of New York, if (but only if) payment of the full
amount thereof in U.S. dollars at all offices or agencies outside the United
States is illegal or effectively precluded by exchange controls or other
similar restrictions.  (Section 1002)

    Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of and any premium and interest on Registered Securities will be
made at the office of such Paying Agent or Paying Agents as the Company may
designate from time to time, except that at the option of the Company payment
of any interest may be made by check mailed on or before the due date to the
address of the Person entitled thereto as such address shall appear in the
Security Register.  (Sections 307, 1002)  Unless otherwise indicated in an
applicable Prospectus Supplement, payment of any installment of interest on
Registered Securities will be made to the Person in whose name such Registered
Security is registered at the close of business on the Regular Record Date for
such interest.  (Section 307)

    Unless otherwise indicated in an applicable Prospectus Supplement, the
Company, at its principal executive offices in Houston, Texas will act as its
own Paying Agent for payments with respect to Debt Securities which are
issuable solely as Registered Securities and the Company will maintain a Paying
Agent outside the United States for payments with respect to Debt Securities
(subject to limitations described above in the case of Bearer Securities) which
are issuable solely as Bearer Securities or as both Registered Securities and
Bearer Securities.  Any Paying Agents outside the United States and any other
Paying Agents in the United States initially designated by Company for the Debt
Securities will be named in an applicable Prospectus Supplement.  The Company
may at any time designate additional Paying Agents or rescind the designation
of any Paying Agent or approve a change in the office through which any Paying
Agent acts, except that, if Debt Securities of a series are issuable solely as
Registered Securities, the Company will be required to maintain a Paying Agent
in each Place of Payment for such series and, if Debt Securities of a series
are issuable as Bearer Securities, the Company will be required to maintain (i)
a Paying Agent in the Borough of Manhattan, The City of New York for principal
payments with respect to any Registered Securities of the series (and for
payments with respect to Bearer Securities of the series in the circumstances
described above, but not otherwise), and (ii) a Paying Agent in a Place of
Payment located outside the United States where Debt Securities of such series
and any coupons appertaining thereto may be presented and surrendered for
payment.  (Section 1002)

    All moneys paid by the Company to a Paying Agent for the payment of
principal of and any premium or interest on any Debt Security which remain
unclaimed at the end of two years after such principal, premium or interest
shall have become due and payable will (subject to applicable escheat laws) be
repaid to the Company, and the Holder of such Debt Security or any coupon will
thereafter look only to the Company for payment thereof.  (Section 1003)

    Global Debt Securities.  Debt Securities of a series may be issued in whole
or in part in the form of one or more global Debt Securities that will be
deposited with, or on behalf of, a depository identified in the Prospectus
Supplement relating to such series.  Global Debt Securities may be issued in
either registered or bearer form and in either temporary or permanent form.
(Section 203)  Unless and until it is exchanged in whole or in part for the
individual Debt Securities represented thereby, a global Debt Security may not
be transferred except as a whole by the depository for such global Debt
Security to a nominee of such depository or by a nominee of such depository to
such depository or another nominee of such depository or by the depository or
any nominee to a successor depository or any nominee of such successor.





                                       8
<PAGE>   10
    The specific terms of the depository arrangement with respect to a series
of Debt Securities and certain limitations and restrictions relating to a
series of Bearer Securities in the form of one or more global Debt Securities
will be described in the Prospectus Supplement relating to such series.

    Events of Default.  Any one of the following events constitutes an Event of
Default under each Indenture with respect to Debt Securities of any series:
(a) failure to pay any interest on any Debt Security of that series when due,
continued for 30 days; (b) failure to pay principal of or any premium on any
Debt Security of that series when due; (c) failure to deposit any sinking fund
payment, when due, in respect of any Debt Security of that series; (d) failure
to perform any other covenant of the Company in such Indenture (other than a
covenant included in such Indenture solely for the benefit of series of any
Debt Securities other than that series), continued for 90 days after written
notice as provided in such Indenture; (e) certain events in bankruptcy,
insolvency or reorganization involving the Company; and (f) any other Event of
Default provided with respect to Debt Securities of that series.  (Section 501)

    If an Event of Default with respect to Debt Securities of any series at the
time Outstanding occurs and is continuing, either the Trustee or the Holders of
at least 25% in aggregate principal amount of the Outstanding Securities of
that series by notice as provided in the applicable Indenture may declare the
principal amount (or, if the Debt Securities of that series are Original Issue
Discount Securities, such portion of the principal amount as may be specified
in the terms of that series) of all the Debt Securities of that series to be
due and payable immediately.  At any time after a declaration of acceleration
with respect to Debt Securities of any series has been made, but before a
judgment or decree for payment of money has been obtained by the Trustee, the
Holders of a majority in aggregate principal amount of the Outstanding
Securities of that series may, under certain circumstances, rescind and annul
such acceleration.  (Section 502)

    Each Indenture provides that, subject to the duty of the Trustee during
default to act with the required standard of care, the Trustee is under no
obligation to exercise any of its rights or powers under such Indenture at the
request or direction of any of the Holders, unless such Holders shall have
offered to the Trustee reasonable indemnity.  (Sections 601, 603)  Subject to
such provisions for the indemnification of the Trustee, the Holders of a
majority in aggregate principal amount of the Outstanding Securities of any
series 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 Debt Securities of that
series; provided, however, that the Trustee is not obligated to take any action
unduly prejudicial to Holders not joining in such direction or involving the
Trustee in personal liability. (Section 512)

    The Company is required to furnish to the Trustee annually a statement as
to the performance by the Company of its obligations under each Indenture and
as to any default in such performance.  (Section 1007)

    Defeasance.  If so specified with respect to any particular series of Debt
Securities issued under an Indenture, the Company may discharge its
indebtedness and its obligations or certain of its obligations under such
Indenture with respect to such series by depositing funds or obligations issued
or guaranteed by the United States of America with the Trustee.  (Sections
1301-1303)

    Defeasance and Discharge.  Each Indenture provides that, if so specified
with respect to the Debt Securities of any series issued under such Indenture
(other than convertible Subordinated Debt Securities), the Company will be
discharged from any and all obligations in respect of the Debt Securities of
such series (except for certain obligations relating to temporary Debt
Securities and exchange of Debt Securities, registration of transfer or
exchange of Debt Securities of such series, replacement of stolen, lost or
mutilated Debt Securities of such series, maintenance of paying agencies to
hold moneys for payment in trust and





                                       9
<PAGE>   11
payment of additional amounts, if any, required in consequence of United States
withholding taxes imposed on payments to non-United States persons) upon the
deposit with the Trustee, in trust, of money and/or U.S. Government Obligations
which through the payment of interest and principal in respect thereof in
accordance with their terms will provide money in an amount sufficient to pay
the principal of (and premium, if any), and each installment of interest on,
the Debt Securities of such series on the Stated Maturity of such payments in
accordance with the terms of such Indenture and the Debt Securities of such
series.  (Sections 1302, 1304)  Such a trust may only be established if, among
other things, the Company has delivered to the Trustee an Opinion of Counsel to
the effect that (i) the Company has received from, or there has been published
by, the Internal Revenue Service a ruling, or (ii) since the date of such
Indenture there has been a change in applicable federal income tax law, in
either case to the effect that, and based thereon such Opinion of Counsel shall
confirm that, the Holders of such series will not recognize income, gain or
loss for federal income tax purposes as a result of such deposit, defeasance
and discharge, and will be subject to federal income tax on the same amounts
and in the same manner and at the same times as would have been the case if
such deposit, defeasance and discharge had not occurred.  (Section 1304)  In
the event of any such defeasance and discharge of Debt Securities of such
series, Holders of such series would be entitled to look only to such trust
fund for payment of principal of and any premium and any interest on their Debt
Securities until Maturity.

    Covenant Defeasance.  Each Indenture also provides that, if so specified
with respect to the Debt Securities of any series issued thereunder, the
Company may omit to comply with certain restrictive covenants, including (in
the case of the Senior Debt Indenture) the covenant described under "Limitation
on Liens" below, but excluding (in the case of the Subordinated Debt Indenture)
any applicable obligation of the Company respecting the conversion of Debt
Securities of such series into Common Stock, and any such omission shall not be
an Event of Default with respect to the Debt Securities of such series, upon
the deposit with the Trustee, in trust, of money and/or U.S. Government
Obligations which through the payment of interest and principal in respect
thereof in accordance with their terms will provide money in an amount
sufficient to pay the principal of (and premium, if any), and each installment
of interest on, the Debt Securities of such series on the Stated Maturity of
such payments in accordance with the terms of such Indenture and the Debt
Securities of such series.  The obligations of the Company under such Indenture
and the Debt Securities of such series other than with respect to such
covenants shall remain in full force and effect.  (Section 1303)  Such a trust
may be established only if, among other things, the Company has delivered to
the Trustee an Opinion of Counsel to the effect that the Holders of such series
will not recognize income, gain or loss for federal income tax purposes as a
result of such deposit and defeasance of certain obligations and will be
subject to federal income tax on the same amounts and in the same manner and at
the same time as would have been the case if such deposit and defeasance had
not occurred. (Section 1304)

    Although the amount of money and U.S. Government Obligations on deposit
with the Trustee would be intended to be sufficient to pay amounts due on the
Debt Securities of such series at the time of their Stated Maturity, in the
event the Company exercise its option to omit compliance with the covenants
deceased with respect to the Debt Securities of any series as described above,
and the Debt Securities of such series are declared due and payable because of
the occurrence of any Event of Default, such amount may not be sufficient to
pay amounts due on the Debt Securities of such series at the time of the
acceleration resulting from such Event of Default.  The Company shall in any
event remain liable for such payments as provided in the applicable Indenture.

    Federal Income Tax Consequences.  Under current United States federal
income tax law, defeasance and discharge would likely be treated as a taxable
exchange of Debt Securities to be defeased for an interest in the defeasance
trust.  As a consequence, a holder would recognize gain or loss equal to the
difference between the holder's cost or other tax basis for such Debt
Securities and the value of the holder's interest in the defeasance





                                       10
<PAGE>   12
trust, and thereafter would be required to include in income the holder's share
of the income, gain or loss of the defeasance trust.  Under current United
States federal income tax law, covenant defeasance would ordinarily not be
treated as a taxable exchange of such Debt Securities.

    Meetings, Modification and Waiver.  Modifications and amendments of either
Indenture may be made by the Company and the Trustee with the consent of the
Holders of a majority in aggregate principal amount of the Outstanding
Securities of each series affected by such modification or amendment; provided,
however, that no such modification or amendment may, without consent of the
Holder of each Outstanding Security affected thereby, (a) change the Stated
Maturity of the principal of, or any installment of principal of or interest
on, any Debt Security, (b) change the Redemption Date with respect to any Debt
Security, (c) reduce the principal amount of, or premium or interest on, any
Debt Security, (d) change any obligation of the Company to pay additional
amounts, (e) reduce the amount of principal of an Original Issue Discount
Security payable upon acceleration of the Maturity thereof, (f) change the coin
or currency in which any Debt Security or any premium or interest thereon is
payable, (g) change the redemption right of any Holder, (h) impair the right to
institute suit for the enforcement of any payment on or with respect to any
Debt Security or any conversion Right with respect thereto, (i) reduce the
percentage in principal amount of Outstanding Securities of any series, the
consent of whose Holders is required for modification or amendment of such
Indenture or for waiver of compliance with certain provisions of such Indenture
or for waiver of certain defaults, (j) reduce the requirements contained in
such Indenture for quorum or voting, (k) change any obligation of the Company
to maintain an office or agency in the places and for the purposes required by
such Indenture, (l) adversely affect the Right to convert Subordinated Debt
Securities, if applicable, or (m) modify any of the above provisions.  (Section
902)

    The Subordinated Debt Indenture may not be amended to alter the
subordination of any outstanding Subordinated Debt Securities without the
consent of each holder of Senior Indebtedness (as defined below under
"--Provisions Applicable Solely to Subordinated Debt Securities") then
outstanding that would be adversely affected thereby.  (Section 907 of the
Subordinated Debt Indenture)

    The Holders of a majority in aggregate principal amount of the Outstanding
Securities of each series may, on behalf of all Holders of that series, waive,
insofar as that series is concerned, compliance by the Company with certain
restrictive provisions of the Indenture under which such series has been
issued.  (Section 1008)  The Holders of a majority in aggregate principal
amount of the Outstanding Securities of each series may, on behalf of all
Holders of that series, waive any past default under the applicable Indenture
with respect to any Debt Securities of that series, except a default (a) in the
payment of principal of, or premium, if any, or any interest on any Debt
Security of such series or (b) in respect of a covenant or provision of such
Indenture which cannot be modified or amended without the consent of the Holder
of each Outstanding Security of such series affected.  (Section 513)

    Each Indenture provides that in determining whether the Holders of the
requisite principal amount of the Outstanding Securities have given any
request, demand, authorization, direction, notice, consent or waiver thereunder
or are present at a meeting of the Holders for quorum purposes, (i) the
principal amount of an Original Issue Discount Security that is deemed to be
Outstanding will be the amount of the principal that would be due and payable
as of the date of such determination upon acceleration of the Maturity thereof,
and (ii) the principal amount of a Debt Security denominated in a foreign
currency or currency units will be the U.S. dollar equivalent, determined on
the date of original issuance of such Debt Security, of the principal amount of
such Debt Security or, in the case of an Original issue Discount Security, the
U.S. dollar equivalent, determined on the date of original issuance of such
Security, of the amount determined as provided in (i) above.  (Section 101)





                                       11
<PAGE>   13
    Each Indenture contains provisions for convening meetings of the Holders of
a series if Debt Securities of that series are issuable as Bearer Securities.
(Section 1401)  A meeting may be called at any time by the Trustee, and also,
upon request, by the Company or the Holders of at least 10% in aggregate
principal amount of the Outstanding Securities of such series, in any such case
upon notice given in accordance with "Notices" below.  (Section 1402)  Except
for any consent which must be given by the Holder of each Outstanding Security
affected thereby, as described above, any resolution presented at a meeting (or
adjourned meeting at which a quorum is present) may be adopted by the
affirmative vote of the Holders of a majority in aggregate principal amount of
the Outstanding Securities of that series; provided, however, that any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other action which may be made, given or taken by
the Holders of a specified percentage, which is less than a majority, in
aggregate principal amount of the Outstanding Securities of a series may be
adopted at a meeting (or adjourned meeting duly reconvened at which a quorum is
present) by the affirmative vote of the Holders of such specified percentage in
aggregate principal amount of the Outstanding Securities of that series.  Any
resolution passed or decision taken at any meeting of Holders of any series
duly held in accordance with the applicable Indenture will be binding on all
Holders of that series and related coupons.  The quorum at any meeting, and at
any reconvened meeting, will be Persons holding or representing a majority in
aggregate principal amount of the Outstanding Securities of a series. (Section
1404)

    Consolidation, Merger and Sale of Assets.  The Company, without the consent
of the Holders of any of the outstanding Securities under either Indenture, may
consolidate with or merge into, or convey, transfer or lease its assets
substantially as an entirety to, any Person which is a corporation partnership
or trust organized and validly existing under the laws of any domestic
jurisdiction, provided that any successor Person assumes the Company's
obligations on the Securities and under such Indenture, that after giving
effect to the transaction no Event of Default, and no event which, after notice
or lapse of time, would become an Event of Default, shall have occurred and be
continuing, and that certain other conditions are met.  (Section 801)

    Notices.  Except as otherwise provided in the Indentures, notices to
Holders of Bearer Securities will be given by publication at least twice in a
daily newspaper in The City of New York and in such other city or cities as may
be specified in such Bearer Securities.  Notices to Holders of Registered
Securities will be given by mail to the addresses of such Holders as they
appear in the Security Register.  (Section 106)

    Title.  Title to any Bearer Securities (including Bearer Securities in
permanent global form) and any coupons appertaining thereto will pass by
delivery.  The Company, the Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer Security and the bearer of any coupon and
the registered owner of any Registered Security as the owner thereof (whether
or not such Debt Security or coupon shall be overdue and notwithstanding any
notice to the contrary) for the purpose of making payment and for all other
purposes.  (Section 308)

    Replacement of Securities and Coupons.  Any mutilated Debt Security or a
Debt Security with a mutilated coupon appertaining thereto will be replaced by
the Company at the expense of the Holder upon surrender of such Debt Security
to the Trustee.  Debt Securities or coupons that became destroyed, stolen or
lost will be replaced by the Company at the expense of the Holder upon delivery
to the Trustee of the Debt Security and coupons or evidence of destruction,
loss or theft thereof satisfactory to the Company and the Trustee; in the case
of any coupon which becomes destroyed, stolen or lost, such coupon will be
replaced by issuance of a new Debt Security in exchange for the Debt Security
to which such coupon appertains.  In the case of a destroyed, lost or stolen
Debt Security or coupon, an indemnity satisfactory to the Trustee and the
Company may be required at the expense of the Holder of such Debt Security or
coupon before a replacement Debt Security will be issued.  (Section 306)





                                       12

    Governing Law.  The Indentures, the Debt Securities and coupons will be
governed by, and construed in accordance with, the laws of the State of New
York.  (Section 113)

    Regarding the Trustee.  The Trustee for each series of Debt Securities will
be identified in the applicable Prospectus Supplement.

    Each Indenture contains certain limitations on the right of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize for its own account on certain property received
in respect of any such claim as security or otherwise.  (Section 613)  The
Trustee is permitted to engage in certain other transactions; however, if it
acquires any conflicting interest (as described in the Indentures), it must
eliminate such conflict or resign.  (Section 608)

    The holders of a majority in principal amount of all outstanding Debt
Securities of a Series (or if more than one Series is affected thereby, all of
Series so affected, voting as a single class) will have the right to direct the
time, method and place of conducting any proceeding for exercising any remedy
or power available to the Trustee for such Series or all such Series so
affected.

    In case an Event of Default shall occur (and shall not be cured) under any
Indenture relating to a Series of Debt Securities and is known to the Trustee
for such Series, such Trustee shall exercise such of the rights and powers
vested in it by such Indenture and use the same degree of care and skill in its
exercise as a prudent person would exercise or use under the circumstances in
the conduct of his own affairs.  Subject to such provisions, no Trustee will be
under any obligation to exercise any of its rights or powers under the
applicable Indenture at the request of any of the holders of Debt Securities
unless they shall have offered to such Trustee security and indemnity
satisfactory to it.

PROVISIONS APPLICABLE SOLELY TO SENIOR DEBT SECURITIES

    General.  Senior Debt Securities will be issued under the Senior Debt
Indenture, and each series will rank pari passu as to the right of payment of
principal and any premium and interest with each other series issued thereunder
and will rank senior to all series of Subordinated Debt Securities that may be
issued.

    Certain Definitions.  For purposes of the following discussion, the
following definitions are applicable (Section 101 of the Senior Debt
Indenture).

    "Net Tangible Assets" means the total amount of assets appearing on a
consolidated balance sheet of the Company and its Subsidiaries less, without
duplication:  (a) total current liabilities (excluding current maturities of
long-term debt and preferred stock); (b) all reserves for depreciation and
other asset valuation reserves but excluding reserves for deferred federal and
state income taxes; (c) all intangible assets such as goodwill, trademarks,
trade names, patents and unamortized debt discount and expense carried as an
asset; and (d) all appropriate adjustments on account of minority interests of
other Persons holding common stock in any Subsidiary.

    "Person" means any individual, corporation, partnership, joint venture,
trust, unincorporated organization or government or any agency or political
subdivision thereof.

    "Subsidiary" means a corporation more than 50% of the outstanding stock of
which is owned, directly or indirectly, by the Company or by one or more
Subsidiaries, or by the Company and one or more other Subsidiaries.  For the
purposes of this definition, "voting stock" means stock which ordinarily has
voting





                                       13
<PAGE>   15
power for the election of directors, whether at all times or only so long as no
senior class of stock has such voting power by reason of any contingency.

PROVISIONS APPLICABLE SOLELY TO SUBORDINATED DEBT SECURITIES

    Subordination.  The Subordinated Debt Securities will be subordinate and
junior in right of payment, to the extent set forth in the Subordinated Debt
Indenture, to all Senior Indebtedness (as defined below) of the Company.  If
the Company should default in the payment of any principal of or premium or
interest on any Senior Indebtedness when the same become due and payable,
whether at maturity or a date fixed for prepayment or by declaration of
acceleration or otherwise, then, upon written notice of such default to the
Company by the holders of such Senior Indebtedness or any trustee therefor and
subject to certain rights of the Company to dispute such default and subject to
proper notification of the Trustee, unless and until such default has been
cured or waived or ceases to exist, no direct or indirect payment (in cash,
property, securities, by set-off or otherwise) will be made or agreed to be
made for principal or premium, if any, or interest, if any, on the Subordinated
Debt Securities, or in respect of any redemption retirement, purchase or other
acquisition of the Subordinated Debt Securities other than those made in
capital stock of the Company (or cash in lieu of fractional shares thereof)
pursuant to any conversion right of the Subordinated Debt Securities or
otherwise made in capital stock of the Company.  (Sections 1601, 1604 and 1605
of the Subordinated Debt Indenture)

    "Senior Indebtedness" is defined in Section 101 of the Subordinated Debt
Indenture as Indebtedness (as defined below) of the Company outstanding at any
time except (a) any Indebtedness as to which, by the terms of the instrument
creating or evidencing the same, it is provided that such Indebtedness is not
senior in right of payment to the Subordinated Debt Securities, (b) the
Subordinated Debt Securities, (c) any Indebtedness of the Company to a
wholly-owned Subsidiary of the Company, (d) interest accruing after the filing
of a petition initiating certain bankruptcy or insolvency proceedings unless
such interest is an allowed claim enforceable against the Company in a
proceeding under federal or state bankruptcy laws, (e) obligations under
performance guarantees, support agreements and other agreements in the nature
thereof relating to the obligations of any Subsidiary of the Company, and (f)
trade accounts payable.  "Indebtedness" is defined in Section 101 of the
Subordinated Debt Indenture as, with respect to any Person, (a) (i) the
principal of and premium and interest, if any, on indebtedness for money
borrowed of such Person evidenced by bonds, notes, debentures or similar
obligations, including any guaranty by such Person of any indebtedness for
money borrowed of any other Person, whether any such indebtedness or guaranty
is outstanding on the date of the Subordinated Debt Indenture or is thereafter
created, assumed or incurred, (ii) the principal of and premium and interest,
if any, on indebtedness for money borrowed, incurred, assumed or guaranteed by
such Person in connection with the acquisition by it or any of its subsidiaries
of any other business, properties or other assets and (iii) lease obligations
which such Person capitalizes in accordance with Statement of Financial
Accounting Standards No. 13 promulgated by the Financial Accounting Standards
Board or such other generally accepted accounting principles as may be from
time to time in effect, (b) any other indebtedness of such Person, including
any indebtedness representing the balance deferred and unpaid of the purchase
price of any property or interest therein, including any such balance that
constitutes a trade account payable, and any guaranty, endorsement or other
contingent obligation of such Person in respect of any indebtedness of another,
which is outstanding on the date of the Subordinated Debt Indenture or is
thereafter created, assumed or incurred by such Person and (c) any amendments,
modifications, refundings, renewals or extensions of any indebtedness or
obligation described as Indebtedness in clause (a) or (b) above.

    If (i) without the consent of the Company a court shall enter (A) an order
for relief with respect to the Company under the United States federal
bankruptcy laws, (B) a judgment, order or decree adjudging the Company a
bankrupt or insolvent, or (C) an order for relief for reorganization,
arrangement, adjustment or





                                       14
<PAGE>   16
composition of or in respect of the Company under the United States federal
bankruptcy laws or state insolvency laws or (ii) the Company shall institute
proceedings for the entry of an order for relief with respect to the Company
under the United States federal bankruptcy laws or for an adjudication of
insolvency, or shall consent to the institution of bankruptcy or insolvency
proceedings against it, or shall file a petition seeking, or seek or consent to
reorganization, arrangement, composition or similar relief under any applicable
law, or shall consent to the filing of such petition or to the appointment of a
receiver, custodian, liquidator, assignee, trustee, sequestrator or similar
official in respect of the Company or of substantially all of its property, or
the Company shall make a general assignment for the benefit of creditors, then
all Senior Indebtedness (including any interest thereon accruing after the
commencement of any such proceedings) will first be paid in full before any
payment or distribution, whether in cash, securities or other property, is made
on account of the principal of, premium, if any, or interest, if any, on the
Subordinated Debt Securities. In such event, any payment or distribution on
account of the principal of, premium, if any, or interest, if any, on the
Subordinated Debt Securities, whether in cash, securities or other property
(other than securities of the Company or any other corporation provided for by
a plan of reorganization or readjustment the payment of which is subordinate,
at least to the extent provided in the subordination provisions with respect to
the Subordinated Debt Securities, to the payment of all Senior Indebtedness
then outstanding and to any securities issued in respect thereof under any such
plan of reorganization or readjustment), which would otherwise (but for the
subordination provisions) be payable or deliverable in respect of the
Subordinated Debt Securities will be paid or delivered directly to the holders
of Senior Indebtedness in accordance with the priorities then existing among
such holders until all Senior Indebtedness (including any interest thereon
accruing after the commencement of any such proceedings) has been paid in full.
If any payment or distribution on account of the principal of, premium, if any,
or interest, if any, on the Subordinated Debt Securities of any character,
whether in cash, securities or other property (other than securities of the
Company or any other corporation provided for by a plan of reorganization or
readjustment the payment of which is subordinate, at least to the extent
provided in the subordination provisions with respect to the Subordinated Debt
Securities, to the payment of all Senior Indebtedness then outstanding and to
any securities issued in respect thereof under any such plan of reorganization
or readjustment), shall be received by the Trustee or any holder of any
Subordinated Debt Securities in contravention of any of the terms of the
Subordinated Debt Indenture, such payment or distribution will be received in
trust for the benefit of, and will be paid over or delivered and transferred
to, the holders of the Senior Indebtedness then outstanding in accordance with
the priorities then existing among such holders for application to the payment
of all Senior Indebtedness remaining unpaid, to the extent necessary to pay all
such Senior Indebtedness in full.  In the event of any such proceeding, after
payment in full of all sums owing with respect to Senior Indebtedness, the
holders of Subordinated Debt Securities, together with the holders of any
obligations of the Company ranking on a parity with the Subordinated Debt
Securities, will be entitled to be repaid from the remaining assets of the
Company the amounts at that time due and owing on account of unpaid principal
of or any premium or interest on the Subordinated Debt Securities and such
other obligations before any payment or other distribution, whether in cash,
property or otherwise, shall be made on account of any capital stock or
obligations of the Company ranking junior to the Subordinated Debt Securities
and such other obligations.  (Section 1601 of the Subordinated Debt Indenture)

    The Prospectus Supplement respecting any series of Subordinated Debt
Securities will set forth any subordination provisions applicable to such
series in addition to or different from those described above.

    By reason of such subordination, in the event of the insolvency of the
Company, holders of Senior Indebtedness and holders of other obligations of the
Company that are not subordinated to Senior Indebtedness may receive more,
ratably, than holders of the Subordinated Debt Securities.  Such subordination
will not prevent the occurrence of an Event of Default or limit the right of
acceleration in respect of the Subordinated Debt Securities.





                                       15
<PAGE>   17
    Conversion.  The Subordinated Debt Indenture may provide for a Right of
conversion of Subordinated Debt Securities into Common Stock (or cash in lieu
thereof).  (Sections 301 and 1501 of the Subordinated Debt Indenture) The
following provisions will apply to Debt Securities that are convertible
Subordinated Debt Securities unless otherwise provided in the Prospectus
Supplement for such Debt Securities.

    The holder of any convertible Subordinated Debt Securities will have the
right exercisable at any time prior to maturity, unless previously redeemed or
otherwise purchased by the Company, to convert such Subordinated Debt
Securities into shares of Common Stock at the conversion price or conversion
rate set forth in the Prospectus Supplement, subject to adjustment.  (Section
1502 of the Subordinated Debt Indenture)  The holder of convertible
Subordinated Debt Securities may convert any portion thereof which is $1,000 in
principal amount or any integral multiple thereof.  (Section 1502 of the
Subordinated Debt Indenture)

    In certain events, the conversion price or conversion rate will be subject
to adjustment as set forth in the Subordinated Debt Indenture.  Such events
include the issuance of shares of Common Stock of the Company as a dividend or
distribution on the Common Stock; subdivisions, combinations and
reclassifications of the Common Stock; the issuance to all holders of Common
Stock of Rights or warrants entitling the holders thereof (for a period not
exceeding 45 days) to subscribe for or purchase shares of Common Stock at a
price per share less than the then current market price per share of Common
Stock (as determined pursuant to the Subordinated Debt Indenture); and the
distribution to substantially all holders of Common Stock of evidences of
indebtedness, equity securities (including equity interests in the Company's
Subsidiaries) other than Common Stock, or other assets (excluding cash
dividends paid from surplus) or subscription Rights or warrants (other than
those referred to above).  No adjustment of the conversion price or conversion
rate will be required unless an adjustment would require a cumulative increase
or decrease of at least 1% in such price or rate.  (Section 1504 of the
Subordinated Debt Indenture)   The Company has been advised by its counsel,
Vinson & Elkins L.L.P., that certain adjustments in the conversion price or
conversion rate in accordance with the foregoing provisions may result in
constructive distributions to either holders of the Subordinated Debt
Securities or holders of Common Stock which would be taxable pursuant to
Treasury Regulations issued under Section 305 of the Internal Revenue Code of
1986, as amended.  The amount of any such taxable constructive distribution
would be the fair market value of the Common Stock which is treated as having
been constructively received, such value being determined as of the time the
adjustment resulting in the constructive distribution is made.

    Fractional shares of Common Stock will not be issued upon conversion, but,
in lieu thereof, the Company will pay a cash adjustment based on the then
current market price for the Common Stock.  (Section 1503 of the Subordinated
Debt Indenture)  Upon conversion, no adjustments will be made for accrued
interest or dividends, and therefore convertible Subordinated Debt Securities
surrendered for conversion between the record date for an interest payment and
the interest payment date (except convertible Subordinated Debt Securities
called for redemption on a redemption date during such period) must be
accompanied by payment of an amount equal to the interest thereon which the
registered holder is to receive.  (Sections 1504 and 1502 of the Subordinated
Debt Indenture)

    In the case of any consolidation or merger of the Company (with certain
exceptions) or any conveyance, transfer or lease of the properties and assets
of the Company substantially as an entirety to any Person, each holder of
convertible Subordinated Debt Securities, after the consolidation, merger,
conveyance, transfer or lease, will have the Right to convert such convertible
Subordinated Debt Securities only into the kind and amount of securities, cash
and other property which the holder would have been entitled to receive upon or
in connection with such consolidation, merger, conveyance, transfer or lease,
if the holder had held the Common Stock issuable upon conversion of such
convertible Subordinated Debt Securities immediately prior





                                       16
<PAGE>   18
to such consolidation, merger, conveyance, transfer or lease. (Section 1505 of
the Subordinated Debt Indenture)

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

    The Company is currently authorized to issue 300,000,000 shares of its
Common Stock, par value $.01 per share, of which 138,343,184 shares were
outstanding on September 30, 1996 and 10,000,000 shares of Preferred Stock, par
value $.01 per share, none were outstanding on such date.

COMMON STOCK

    Each holder of Common Stock is entitled to one vote per share held of
record on each matter submitted to stockholders.  Cumulative voting for the
election of directors is not permitted, and the holders of a majority of shares
voting for the election of directors can election all members of the Board of
Directors.

    Subject to the rights of any holders of Preferred Stock, holders of record
of shares of Common Stock are entitled to receive ratably dividends when and if
declared by the Board of Directors out of funds legally available therefor.  In
the event of a voluntary or involuntary winding up or dissolution, liquidation
or partial liquidation of the Company, holders of Common Stock are entitled to
participate ratably in any distribution of the assets of the Company, subject
to any prior rights of holders of any outstanding Preferred Stock.

    Holders of Common Stock have no conversion, redemption or preemptive
rights.  All outstanding shares of Common Stock are, and the Common Stock to be
issued hereunder will be, validly issued, fully paid and nonassessable.

PREFERRED STOCK

    The Board of Directors is authorized, without further approval of the
stockholders, to issue the Preferred Stock in series and with respect to each
series, to fix its designations, relative rights (including voting, dividend,
conversion, sinking fund and redemption rights), preferences (including with
respect to dividends and upon liquidation), privileges and limitations.  The
Board of Directors, without stockholder approval, may issue Preferred Stock
with voting and conversion rights, both of which could adversely affect the
voting power of the holders of Common Stock, and dividend or liquidation
preferences that would restrict Common Stock dividends or adversely affect the
assets available for distribution to holders of shares of Common Stock upon the
Company's dissolution.

AUTHORIZED BUT UNISSUED SHARES

    Authorized but unissued shares of Common Stock or Preferred Stock can be
reserved for issuance by the Board of Directors from time to time without
further stockholder action for proper corporate purposes, including stock
dividends or stock splits, raising equity capital and structuring future
corporate transactions, including acquisitions.

TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for the Common Stock is Boston EquiServe,
Boston, Massachusetts.





                                       17

DELAWARE ANTI-TAKEOVER LAW

    Section 203 of the DGCL ("Section 203") generally provides that a person
who, together with affiliates and associates owns, or within three years did
own, at least 15% but less than 85% of the outstanding voting stock of a
corporation subject to the statute (an "Interested Stockholder") may not engage
in certain business combinations with the corporation for a period of three
years after the date of which the person became an Interested Stockholder
unless (i) prior to such date, the corporation's board of directors approved
either the business combination or the transaction in which the stockholder
became an Interested Stockholder or (ii) subsequent to such date, the business
combination is approved by the corporation's board of directors and authorized
at a stockholders' meeting by a vote of at least two- thirds of the
corporation's outstanding voting stock not owned by the Interested Stockholder.
Section 203 defines the term "business combination" to encompass a wide variety
of transactions with or caused by an Interested Stockholder, including mergers,
asset sales, and other transactions in which the Interested Stockholder
receives or could receive a benefit on other than a pro rata basis with other
stockholders.

    The provisions of Section 203, combined with the Board's authority to issue
Preferred Stock without further stockholder action, could delay or frustrate a
change in control of the Company.  The provisions also could discourage, impede
or prevent a merger, tender offer or proxy content, even if such event would be
favorable to the interests of stockholders.  The Company's stockholders, by
adopting an amendment to the Restated Certificate of Incorporation, may elect
not to be governed by Section 203 which election would be effective 12 months
after such adoption.  Neither the Restated Certificate of Incorporation nor the
Bylaws exclude the Company from the restrictions imposed by Section 203.

                              PLAN OF DISTRIBUTION

GENERAL

    The Company may sell Securities to or through underwriters or dealers, and
also may sell Securities directly to other purchasers or through agents.

    The distribution of the Securities may be effected from time to time in one
or more transactions at a fixed price or prices, which may be changed, or at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.

    In connection with the sale of Securities, underwriters may receive
compensation from the Company, or purchasers of Securities for whom they may
act as agents in the form of discounts, concessions or commissions.
Underwriters, dealers and agents that participate in the distribution of
Securities may be deemed to be underwriters, and any discounts or commissions
received by them from the Company or the Selling Stockholders, as the case may
be, and any profit on the resale of Securities by them may be deemed to be
underwriting discounts and commissions under the Securities Act.  Any such
person who may be deemed to be an underwriter will be identified, and any such
compensation received from the Company will be described, in the Prospectus
Supplement.

    Debt Securities, when first issued, will have no established trading
market.  Any underwriters or agents to or through whom Debt Securities are sold
by the Company for public offering and sale may make a market in such Debt
Securities, but such underwriters or agents will not be obligated to do so and
may discontinue any market making at any time without notice.  No assurance can
be given as to the liquidity of the trading market for any Debt Securities.





                                       18
<PAGE>   20
    Under agreements which may be entered into by the Company, underwriters,
dealers and agents who participate in the distribution of Securities may be
entitled to indemnification by the Company against or contribution toward
certain liabilities, including liabilities under the Securities Act.

DELAYED DELIVERY ARRANGEMENT

    If so indicated in the Prospectus Supplement, the Company will authorize
underwriters or other persons acting as the Company's agents to solicit offers
by certain institutions to purchase Debt Securities from the Company pursuant
to contracts providing for payment and delivery on a future date.  Institutions
with which such contracts may be made include commercial and savings banks,
insurance companies, pension funds, investment companies, educational and
charitable institutions and others, but in all cases will be subject to the
approval of the Company.  The obligations of any purchaser under any such
contract will be subject to the condition that the purchase of the Debt
Securities shall not at the time of delivery be prohibited under the laws of
any jurisdiction to which such purchaser is subject.  The underwriters and such
agents will not have any responsibility in respect of the validity or
performance of such contracts.

                             VALIDITY OF SECURITIES

    The validity of the Offered Securities, as well as certain tax matters in
connection therewith, will be passed upon for the Company by Vinson & Elkins
L.L.P., Houston, Texas  and will be passed upon for any agents, dealers or
underwriters by counsel named in the applicable Prospectus Supplement.

ITEM 15.     INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Under Delaware law, a corporation may include provisions in its certificate
of incorporation that will relieve its directors of monetary liability for
breaches of their fiduciary duty to the corporation, except under certain
circumstances, including a breach of the directors's duty of loyalty, acts or
omissions of the director not in good faith or which involve intentional
misconduct or a knowing violation of law, the approval of an improper payment
of a dividend or an improper purchase by the corporation of stock or any
transaction from which the director derived an improper personal benefit.  The
Company's Restated Certificate of Incorporation provides that the Company's
directors are not liable to the Company or its stockholders for monetary
damages for breach of their fiduciary duty, subject to the described exceptions
specified by Delaware law.

    Section 145 of the Delaware General Corporation Law grants to the Company
the power to indemnify each officer and director of the Company against
liabilities and expenses incurred by reason of the fact that he is or was an
officer or director of the Company if he acted in good faith and  in a manner
he reasonably believed to be in or not opposed to the best interests of the
Company and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The By-laws of the
Company provide for indemnification of each officer and director of the Company
to the fullest extent permitted by Delaware law.





                                      II-1
<PAGE>   22
    Section 145 of the Delaware General Corporation Law also empowers the
Company to purchase and maintain insurance on behalf of any person who is or
was an officer or director of the Company against liability asserted against or
incurred by him in any such capacity, whether or not the Company would have the
power to indemnify such officer or director against such liability under the
provisions of Section 145.  The Company has purchased and maintains a
directors' and officers' liability policy for such purposes.

    The Company has entered into Indemnification Agreements with each of its
directors and executive officers.  Such Indemnification Agreements provide that
such persons (the "Indemnitees") will be indemnified and held harmless from all
expenses, including (without limitation) reasonable fees and expenses of
counsel, and all liabilities, including (without limitation) the amount of any
judgments, fines, penalties, excise taxes and amounts paid in settlement,
actually incurred by an Indemnitee with respect to any threatened, pending or
completed claim, action (including any action by or in the right of the
Company), suit or proceeding (whether formal or informal, or civil, criminal,
administrative, legislative, arbitrative or investigative) in respect of which
such Indemnitee is, was or at any time becomes, or is threatened to be made, a
party, witness, subject or target, by reason of the fact that such Indemnitee
is or was a director, officer, agent or fiduciary of the Company or serving at
the request of the Company as a director, officer, employee, fiduciary or
representative or another enterprise.  Such Indemnification Agreements also
provide that the Company, if requested to do so by an Indemnitee, will advance
to such Indemnitee, prior to final disposition of any proceeding, the expenses
actually incurred by the Indemnitee subject to the obligation of the Indemnitee
to refund if it is ultimately determined that such Indemnitee was not entitled
to indemnification.

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;

             (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; notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if  the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the
         estimated maximum offering range may be reflected in the form of
         prospectus filed with the Commission pursuant to Rule 424(b) if, in
         the aggregate, the changes





                                      II-4
<PAGE>   25
         in volume and price represent no more than a 20% change in the maximum
         aggregate offering price set forth in the "Calculation of Registration
         Fee" table in the effective registration statement;

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

    provided however, that paragraphs (a)(l)(i) and (a)(l)(ii) do not apply if
    the information required to be included in a post-effective amendment by
    those paragraphs is contained in periodic reports filed with or furnished
    to the Commission by the registrant pursuant to Section 13 or Section 15(d)
    of the Exchange Act that are incorporated by reference in the registration
    statement.

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

         (1) For purposes of determining any liability under the Securities
    Act, the information omitted from the form of prospectus filed as part of
    this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
    (4) or 497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.

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

    (c)  The registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and,
where applicable, each filing of an employee benefits plan's annual report
pursuant to Section 15(d) of the Exchange Act) 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.

    (d)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to any charter provision, by-law, contract,
arrangement, statute, or otherwise, the Company has been advised that in the
opinion of the 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 labilities (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 against the registrant by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction





                                      II-5
<PAGE>   26
the question of 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.

         306 or in exchange for or in lieu of which other Securities have been
         authenticated and delivered pursuant to this Indenture, other than any
         such Securities in respect of which there shall have been presented to
         the Trustee proof satisfactory to it that such Securities are held by
         a bona fide purchaser in whose hands such Securities are valid
         obligations of the Company;

provided, however, that in determining whether the Holders of the requisite
principal amount of the Outstanding Securities have given any request, demand,
authorization, direction, notice, consent or waiver hereunder or whether a
quorum is present at a meeting of Holders of Securities (i) the principal
amount of an Original Issue Discount Security that shall be deemed to be
Outstanding shall be the amount of the principal thereof that would be due and
payable as of the date of such determination upon acceleration of the Maturity
thereof pursuant to Section 502, (ii) the principal amount of a Security
denominated in a foreign currency or currencies, including composite
currencies, shall be the Dollar equivalent, determined on the date of original
issuance of such Security in the manner provided as contemplated by Section
301, of the principal amount (or, in the case of an Original Issue Discount
Security, the Dollar equivalent on the date of original issuance of such
Security of the amount determined as provided in (i) above) of such Security,
and (iii) Securities owned by the Company or any other obligor upon the
Securities or any Affiliate of the





                                       5
<PAGE>   12
Company or of such other obligor shall be disregarded and deemed not to be
Outstanding, except that, in determining whether the Trustee shall be protected
in relying upon any such request, demand, authorization, direction, notice,
consent or waiver, or upon any such determination as to the presence of a
quorum, only Securities which the Trustee knows to be so owned shall be so
disregarded.  Securities so owned which have been pledged in good faith may be
regarded as Outstanding if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with respect to such Securities and that
the pledgee is not the Company or any other obligor upon the Securities or any
Affiliate of the Company or of such other obligor.

         Upon any application or request by the Company to the Trustee to take
any action under any provision of this Indenture, the Company shall furnish to
the Trustee such certificates and opinions as may be required under the Trust
Indenture Act.  Each such certificate or opinion shall be given in the form of
an Officers' Certificate, if to be given by an officer of the Company, or an
Opinion of Counsel, if to be given by counsel, and shall comply with the
requirements of the Trust Indenture Act and any other requirements set forth in
this Indenture.

SECTION 103.  Form of Documents Delivered to Trustee.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

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

SECTION 104.  Acts of Holders.

         (a)     Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing.  If Securities of a series are issuable as Bearer
Securities, any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of such series may, alternatively, be embodied in and evidenced by the
record of Holders of Securities of such series voting in favor thereof, either
in





                                       8
<PAGE>   15
person or by proxies duly appointed in writing, at any meeting of Holders of
Securities of such series duly called and held in accordance with the
provisions of Article Fourteen, or a combination of such instruments and any
such record.  Except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments or record or both are
delivered to the Trustee and, where it is hereby expressly required, to the
Company.  Such instrument or instruments and any such record (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments and so voting at
any such meeting.  Proof of execution of any such instrument or of a writing
appointing any such agent or proxy or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 601) conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.  The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1406.

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

         (c)     The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining
the Holders of Registered Securities of any series entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action, or to vote on any action, authorized or permitted to be given or taken
by Holders of Securities of such series.  If not set by the Company prior to
the first solicitation of a Holder of Securities of such series made by any
Person in respect of any such action, or, in the case of any such vote, prior
to such vote, the record date for any such action or vote shall be the 30th day
(or, if later, the date of the most recent list of Holders required to be
provided pursuant to Section 701) prior to such first solicitation or vote, as
the case may be.  With regard to any record date for action to be taken by the
Holders of one or more series of Securities, only the Holders of Securities of
such series on such date (or their duly designated proxies) shall be entitled
to give or take, or vote on, the relevant action.

         (d)     The principal amount and serial numbers of Registered
Securities held by any Person, and the date of holding the same, shall be
proved by the Security Register.

         (e)     The principal amount and serial numbers of Bearer Securities
held by any Person, and the date of holding the same, may be proved by the
production of such Bearer Securities or by a certificate executed, as
depositary, by any trust company, bank, banker or other depositary, wherever
situated, if such certificate shall be deemed by the Trustee to be
satisfactory, showing that at the date therein mentioned such Person had on
deposit with such depositary, or exhibited to it, the Bearer Securities therein
described; or such facts may be proved by the certificate or affidavit of the
Person holding such Bearer Securities, if such certificate or affidavit is
deemed by the Trustee to be





                                       9
<PAGE>   16
satisfactory.  The Trustee and the Company may assume that such ownership of
any Bearer Security continues until (1) another certificate or affidavit
bearing a later date issued in respect of the same Bearer Security is produced,
or (2) such Bearer Security is produced to the Trustee by some other Person, or
(3) such Bearer Security is surrendered in exchange for a Registered Security,
or (4) such Bearer Security is no longer Outstanding.  The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner which the Trustee deems
sufficient.

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

         (g)     Without limiting the foregoing, a Holder entitled hereunder to
give or 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 different part of such principal amount.

SECTION 105.  Notices, Etc., to Trustee and Company.

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

                 (1)      the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         Attention: Corporate Trust Department, or

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

SECTION 106.  Notice to Holders of Securities; Waiver.

         Except as other vise expressly provided herein, where this Indenture 
provides for notice to Holders of Securities of any event,

                 (1)      such notice shall be sufficiently given to Holders of
         Registered Securities if in writing and mailed, first-class postage
         prepaid, to each Holder of a Registered Security affected by such
         event, at the address of such Holder as it appears in the Security
         Register, not later than the latest date, and not earlier than the
         earliest date, prescribed for the giving of such notice; and





                                       10
<PAGE>   17
                 (2)      such notice shall be sufficiently given to Holders of
         Bearer Securities if published in an Authorized Newspaper in The City
         of New York and in such other city or cities as may be specified in
         such Securities on a Business Day at least twice, the first such
         publication to be not earlier than the earliest date, and not later
         than the latest date, prescribed for the giving of such notice.

         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 to
Holders of Registered Securities by mail, then such notification as shall be
made with the approval of the Trustee shall constitute sufficient notice to
such Holders for every purpose hereunder.  In any case where notice to Holders
of Registered Securities is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder of a
Registered Security shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein.

         In case by the reason of the suspension of publication of any
Authorized Newspaper or Authorized Newspapers or by reason of any other cause
it shall be impracticable to publish any notice to Holders of Bearer Securities
as provided above, then such notification to Holders of Bearer Securities as
shall be given with the approval of the Trustee shall constitute sufficient
notice to such Holders for every purpose hereunder.  Neither the failure to
give notice by publication to Holders of Bearer Securities as provided above,
nor any defect in any notice so published, shall affect the sufficiency of any
notice to Holders of Registered Securities given as provided herein.

         Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders of Securities shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

SECTION 107.  Language of Notices, Etc.

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

SECTION 108.  Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control.  If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall
be deemed to apply to this Indenture as so modified or to be excluded, as the
case may be.

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

SECTION 110.  Successors and Assigns.

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

SECTION 111.  Separability Clause.

         In case any provision in this Indenture or the Securities or coupons
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 112.  Benefits of Indenture.

         Nothing in this Indenture or the Securities or coupons, express or
implied, shall give to any Person, other than the parties hereto, their
successors hereunder and the Holders of Securities and coupons, any benefit or
any legal or equitable right, remedy or claim under this Indenture.

SECTION 113.  Governing Law.

         This Indenture and the Securities and coupons shall be governed by and
construed in accordance with the laws of the State of New York.

SECTION 114.  Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities or coupons other than a provision in the Securities of any series
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 at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be.

Securities, if any, of each series and related coupons shall be in
substantially the form (including temporary or permanent global form) as shall
be established by or pursuant to a Board Resolution or in one or more
indentures supplemental hereto, in each case with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by
this Indenture, and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as may be
required to comply with law, or with the rules of any securities exchange or to
conform to general, usage, all as may, consistently herewith, be determined by
the officers executing such Securities or coupons, as evidenced by their
execution of the Securities or coupons.  If temporary Securities of any series
are issued in global form as permitted by Section 304, the form thereof shall
be established as provided in the preceding sentence.  A copy of the Board
Resolution establishing the forms of Securities or coupons of any series (or
any such temporary global Security) shall be certified by the Secretary or an
Assistant Secretary of the Company and delivered to the Trustee at or prior to
the delivery of the Company Order contemplated by Section 303 for the
authentication and delivery of such Securities (or any such temporary global
Security) or coupons.

         Unless otherwise specified as contemplated by Section 301, Securities
in bearer form shall have interest coupons attached.

         The definitive Securities and coupons, if any, shall be printed,
lithographed or engraved on steel engraved borders or may be produced in any
other manner, all as determined by the officers executing such Securities, as
evidenced by their execution of such Securities or coupons.

SECTION 203.  Securities in Global Form.

         If Securities of a series are issuable in global form, as specified as
contemplated by Section 301, then, notwithstanding clause (10) of Section 301
and the provisions of Section 302, any such Security shall represent such of
the Outstanding Securities of such series as shall be specified therein and may
provide that it shall represent the aggregate amount of Outstanding Securities
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities represented thereby may be reduced to reflect exchanges.  Any
endorsement of a Security in global form to reflect the amount, or any increase
or decrease in the amount, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner and upon instructions given by such
Person or Persons as shall be specified therein or in the Company Order to be
delivered to the Trustee pursuant to Section 303 or Section 304.  Subject to
the provisions of Section 303 and, if applicable, Section 304, the Trustee
shall deliver and redeliver any Security in permanent global form in the manner
and upon instructions given by the Person or Persons specified therein or in
the applicable Company Order.  If a Company Order pursuant to Section 303 or
304 has been, or simultaneously is, delivered, any instructions by the Company
with respect to endorsement or delivery or redelivery of a Security in global
form shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

         Notwithstanding the provisions of Sections 201 and 307, unless
otherwise specified as contemplated by Section 301, payment of principal of and
any premium and interest on any Security in permanent global form shall be made
to the Person or Persons specified therein.

SECTION 204.  Form of Legend for Book-Entry Securities.

         Any Book-Entry Security authenticated and delivered hereunder shall
bear a legend in substantially the following form:

         "This Security is a Book-Entry Security within the meaning of the
Indenture hereinafter referred to and is registered in the name of a Depository
or a nominee of a Depository.  This Security is exchangeable for Securities
registered in the name of a Person other than the Depository or its nominee
only in the limited circumstances described in the Indenture, and no transfer
of this Security (other than a transfer of this Security as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository) may be registered except
in such limited circumstances."

SECTION 301.  Amount Unlimited; Issuable in Series.

         The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is unlimited.

         The Securities may be issued in one or more series, and each such
series shall rank equally and pari passu with each other series.  There shall
be established in or pursuant to a Board Resolution and, subject to Section
303, set forth, or determined in the manner provided, in an Officers'
Certificate, or established in one or more indentures supplemental hereto,
prior to the issuance of Securities of any series:

         306, 906 or 1107 and except for any Securities which, pursuant to
         Section 303, are deemed never to have been authenticated and delivered
         hereunder);

                 (3)      whether Securities of the series are to be issuable
         as Registered Securities, Bearer Securities or both, whether any
         Securities of the series are to be issuable initially in temporary
         global form and whether any Securities of the series are to be
         issuable in permanent global form with or without coupons and, if so,
         whether beneficial owners of interests in any such permanent global
         Security may exchange such interests for Securities of such series and
         of like tenor of any authorized form and denomination and the
         circumstances under which any such exchanges may occur, if other than
         in the manner provided in Section 305;

                 (4)      the Person to whom any interest on any Registered
         Security of the series shall be payable, if other than 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, the manner in which, or the Person to whom, any
         interest on any Bearer Security of the series shall be payable, if
         otherwise than upon presentation and surrender of the coupons
         appertaining thereto as they severally mature and the extent to which,
         or the manner in which, any interest payable on a temporary global
         Security on an Interest Payment Date will be paid if other than in the
         manner provided in Section 304;

                 (5)      the date or dates on which the principal of the
         Securities of the series is payable;

<PAGE>   22
                 (6)      the rate or rates at which the Securities of the
         series shall bear interest, if any, or the method by which such rate
         shall be determined, the date or dates from which any such interest
         shall accrue, the Interest Payment Dates on which any such interest
         shall be payable, and the Regular Record Date for any interest payable
         on any Registered Securities on any Interest Payment Date and whether,
         and under what circumstances, additional amounts with respect to such
         Securities shall be payable as set forth in Section 1001;

                 (7)      the place or places where, subject to the provisions
         of Section 1002, the principal of and any premium and interest on
         Securities of the series shall be payable, any Registered Securities

         Securities of the series, in whole or in part, at its option and the
         period or periods within which, the price or prices at which and the
         terms and conditions upon which Securities of the series may be so
         redeemed;

                 (9)      the obligation, if any, of the Company to redeem,
         purchase, or repay Securities of the series pursuant to any mandatory

         premium or interest on any Securities of the series may be determined
         with reference to an index, the manner in which such amounts shall be

<PAGE>   23
                 (14)     if the principal of and any premium or interest on
         the Securities of the series are to be payable, at the election of the
         Company or a Holder thereof, in a currency or currencies, including
         composite currencies, other than that or those in which the Securities
         are stated to be payable, the currency or currencies in which payment

                 (15)     whether the Securities of the series shall be issued

         of such Book-Entry Security may be registered to, a Person other than
         such Depository or its nominee, if other than as set forth in Section
         305;

                 (16)     if either or both of the provisions of Section 1302
         or 1303 are applicable to the Securities of such series and any

         additional conditions to the provisions of Section 1302 or 1303;

                 (17)     any other Events of Default or covenants with respect
         to the Securities of such series; and

                 (18)     any other terms of the series (which terms shall not
         be inconsistent with the provisions of this Indenture except as
         permitted by Section 901(5)).

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in
the case of Registered Securities, 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 Officers' 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 Company
and delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

SECTION 302.  Denominations.

         Unless otherwise provided as contemplated by Section 301 with respect

                                       17

SECTION 303.  Execution, Authentication, Delivery and Dating.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, a Vice Chairman of the Board, its President, its
Treasurer or its Chief Financial Officer, under its corporate seal reproduced
thereon attested by its Secretary or one of its Assistant Secretaries.  The
signature of any of these officers on the Securities may be manual or
facsimile.  Coupons shall bear the facsimile signature of the Treasurer or any
Assistant Treasurer of the Company.

         Securities and coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, 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 Company may deliver Securities of any series, together with
any coupons appertaining thereto, executed by the Company 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,
unless otherwise provided with respect to such series, in connection with its
original issuance, no Bearer Security shall be mailed or otherwise delivered to
any location in the United States; and provided, further, that, unless
otherwise provided with respect to such series, a Bearer Security may be
delivered in connection with its original issuance only if the Person entitled
to receive such Bearer Security shall have furnished a certificate in the form
set forth in Exhibit A to this Indenture, dated no earlier than the
Certification Date.  If any Security shall be represented by a permanent global
Bearer Security, then, for purposes of this Section and Section 304, the
notation of a beneficial owner's interest therein upon original issuance of
such Security or upon exchange of a portion of a temporary global Security
shall be deemed to be delivery in connection with its original issuance of such
beneficial owner's interest in such permanent global Security.  Except as
permitted by Section 306, the Trustee shall not authenticate and deliver any
Bearer Security unless all appurtenant coupons for interest then matured have
been detached and canceled.

         In authenticating 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:

                 (a)      that the forms of such Securities and coupons
         established by or pursuant to a Board Resolution as contemplated by
         Section 201 have been established in conformity with the provisions of
         this Indenture;

                 (b)      if the terms of such Securities and any coupons have
         been established by or pursuant to a Board Resolution as permitted by
         Section 301, that such terms have been established in conformity with
         the provisions of this Indenture; and





                                       18
<PAGE>   25
                 (c)      that such Securities, together with any coupons
         appertaining thereto, when authenticated and delivered by the Trustee
         and issued by the Company in the manner and subject to any conditions
         specified in such Opinion of Counsel, will constitute valid and
         legally binding obligations of the Company enforceable in accordance
         with their terms, subject to bankruptcy, insolvency, fraudulent
         transfer, reorganization and other laws of general applicability
         relating to or affecting creditors' rights and to general equity
         principles.

Such Opinion of Counsel shall also cover such other matters as the Trustee may
reasonably request.

         The Trustee shall not be required to authenticate such Securities the
forms or terms of which have been established by or pursuant to a Board
Resolution 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 two preceding
paragraphs, if all Securities of a series are not to be originally issued at
one time, it shall not be necessary to deliver the Officers' Certificate
otherwise required pursuant to Section 301 or the Company Order and Opinion of
Counsel otherwise required pursuant to such preceding paragraphs at or prior to
the time of authentication of each Security of such series if such documents
are delivered at or prior to the authentication upon issuance of the first
Security of such series to be issued.

         After the original issuance of the first Security of such series to be
issued, any separate request by the Company that the Trustee authenticate
Securities of such series for original issuance will be deemed to be a
certification by the Company (which, subject to Section 601, the Trustee shall
be fully protected in relying on) that it is in compliance with all conditions
precedent provided for in this Indenture relating to the authentication and
delivery of such Securities.

         Each Registered Security shall be dated the date of its
authentication; and each Bearer Security shall be dated as of the date of
original issuance of the first Security of such series to be issued.

         No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on
such Security, or the Security to which such coupon appertains, a certificate
of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder.  Notwithstanding the foregoing, if any
Security shall have been authenticated and delivered hereunder but never issued
and sold by the Company, and the Company shall deliver such Security to the
Trustee for cancellation as provided in Section 309 together with a written
statement (which need not comply with Section 102 and need not be accompanied
by an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, 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
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued, in registered
form or, if authorized, in bearer form with one or more coupons or without
coupons, 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.  In the case of any series
issuable as Bearer Securities, such temporary Securities may be in global form.
A temporary Bearer Security shall be delivered only in compliance with the
conditions set forth in Section 303.

         Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company 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 Company maintained pursuant to Section 1002 in a Place
of Payment for such series for the purpose of exchanges of Securities of such
series without charge to the Holder.  Upon surrender for cancellation of any
one or more temporary Securities of any series (accompanied by any unmatured
coupons appertaining thereto) the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like aggregate principal amount
of definitive Securities of the same series and of like tenor of authorized
denominations; provided, however, that no definitive Bearer Security shall be
issued in exchange for a temporary Registered Security.

         If temporary Securities of any series are issued in global form, any
such temporary global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the
"Common Depositary"), for the benefit of Euro-clear and CEDEL S.A., for credit
to the respective accounts of the beneficial owners of such Securities (or to
such other accounts as they may direct).

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security of a series (the "Exchange Date"), the Company shall deliver to the
Trustee definitive Securities of that series in aggregate principal amount
equal to the principal amount of such temporary global Security, executed by
the Company.  On or after the Exchange Date such temporary global Security
shall be surrendered by the Common Depositary to the Trustee, as the Company's
agent for such purpose, to be exchanged, in whole or from time to time in part,
for definitive Securities of that series without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary global
Security, a like aggregate principal amount of definitive Securities of the
same series of authorized denominations and of like tenor as the portion of
such temporary global Security to be exchanged; provided, however, that, unless
otherwise specified in such temporary global Security, upon such presentation
by the Common Depositary, such temporary





                                       20
<PAGE>   27
global Security is accompanied by a certificate dated the Exchange Date or a
subsequent date and signed by Euro-clear as to the portion of such temporary
global Security held for its account then to be exchanged and a certificate
dated the Exchange Date or a subsequent date and signed by CEDEL S.A. as to the
portion of such temporary global Security held for its account then to be
exchanged, each in the form set forth in Exhibit B to this Indenture.  The
definitive Securities to be delivered in exchange for any such temporary global
Security shall be in bearer form, registered form, permanent global bearer form
or permanent global registered form, or any combination thereof, as specified
as contemplated by Section 301, and if any combination thereof is so specified,
as requested by the beneficial owner thereof; provided, however, that no
definitive Bearer Security or permanent global Security shall be delivered in
exchange for a temporary Bearer Security except in compliance with the
conditions set forth in Section 303.

         Unless otherwise specified in the temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged on the Exchange Date for definitive Securities (and
where the form of the definitive Securities is not specified by the Holder for
an interest in a permanent global Security) of the same series and of like
tenor unless, on or prior to the Exchange Date, such beneficial owner has not
delivered to Euro-clear or CEDEL S.A., as the case may be, a certificate in the
form set forth in Exhibit A to this Indenture dated no earlier than the
Certification Date, copies of which certificate shall be available from the
offices of Euro-clear and CEDEL S.A., the Trustee, any Authenticating Agent
appointed for such series of Securities and each Paying Agent and after the
Exchange Date, the interest of a beneficial owner of Securities of a series in
a temporary global Security shall be exchanged for definitive Securities (and
where the form of the definitive Securities is not specified by the Holder for
an interest in a permanent global Security) of the same series and of like
tenor following such beneficial owner's delivery to Euro-clear or CEDEL S.A.,
as the case may be, of a certificate in the form set forth in Exhibit A to this
Indenture dated no earlier than the Certification Date.  Unless otherwise
specified in such temporary global Security; any exchange shall be made free of
charge to the beneficial owners of such temporary global Security, except that
a Person receiving definitive Securities must bear the cost of insurance,
postage, transportation and the like in the event that such Person does not
take delivery of such definitive Securities in person at the offices of
Euro-clear or CEDEL S.A. Definitive Securities in bearer form to be delivered
in exchange for any portion of a temporary global Security shall be delivered
only outside the United States.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary
global Security on an Interest Payment Date for Securities of such series shall
be payable to Euro-clear and CEDEL S.A. on such Interest Payment Date upon
delivery by Euro-clear and CEDEL S.A. to the Trustee of a certificate or
certificates in the form set forth in Exhibit B to this Indenture, for credit
without further interest on or after such Interest Payment Date to the
respective accounts of the Persons who are the beneficial owners of such
temporary global Security on such Interest Payment Date and who have each
delivered to Euro-clear or CEDEL S.A., as the case may be, a certificate in the
form set forth in Exhibit A to this Indenture.  Any interest so received by
Euro-clear and CEDEL S.A. and not paid as herein provided shall be returned to
the Trustee immediately prior to the expiration of two years after such
Interest Payment Date in order to be repaid to the Company in accordance with
Section 1003.

SECTION 305.  Registration, Registration of Transfer and Exchange.

         The Company shall cause to be kept at an office or agency to be
maintained by the Company in accordance with Section 1002 a register (being the
combined register of the Security Registrar and all transfer agents designated
pursuant to Section 1002 for the purpose of registration of transfer of
Securities and sometimes collectively referred to as the "Security Register")
in which, subject to such reasonable regulations as it may prescribe, the
Company shall provide for the registration of each series of Registered
Securities and the registration of transfers of such Registered Securities.
The Company shall serve initially as "Security Registrar" for the purpose of
registering Registered Securities and transfers of Registered Securities as
herein provided.

         Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency of the Company maintained pursuant to
Section 1002 for such purpose in a Place of Payment for such series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Registered
Securities of the same series of any authorized denominations and of a like
aggregate principal amount and tenor.

         At the option of the Holder, Registered Securities of any series may
be exchanged for other Registered Securities of the same series of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at any such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.  Unless otherwise
provided with respect to any series of Securities, Bearer Securities may not be
issued in exchange for Registered Securities.

         At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon
surrender of the Bearer Securities to be exchanged at any such office or
agency, with all unmatured coupons and all matured coupons in default thereto
appertaining.  If the Holder of a Bearer Security is unable to produce any such
unmatured coupon or coupons or matured coupon or coupons in default, such
exchange may be effected if the Bearer Securities are accompanied by payment in
funds acceptable to the Company in an amount equal to the face amount of such
missing coupon or coupons, or the surrender of such missing coupon or coupons
may be waived by the Company and the Trustee if there is furnished to them such
security or indemnity as they may require to save each of them and any Paying
Agent harmless.  If thereafter the Holder of such Security shall surrender to
any Paying Agent any such missing coupon in respect of which such a payment
shall have been made, such Holder shall be entitled to receive the amount of
such payment; provided, however, that, except as otherwise provided in Section
1002, interest represented by coupons shall be payable only upon presentation
and surrender of those coupons at an office or agency located outside the
United States.  Notwithstanding the foregoing, in case a Bearer Security of any
series is surrendered at any such office or agency in exchange for a Registered
Security of the same series and like tenor after the close of business at such
office or agency on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or
(ii) any Special Record Date and before the opening of business at such office
or





                                       22
<PAGE>   29
agency on the related proposed date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

         Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be
exchangeable only as provided in this paragraph.  If the beneficial owners of
interests in a permanent global Security are entitled to exchange such
interests for Securities of such series and of like tenor and principal amount
of another authorized form and denomination, as specified as contemplated by
Section 301, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities of that series in an aggregate
principal amount equal to the principal amount of such permanent global
Security, executed by the Company.  On or after the earliest date on which such
interests may be so exchanged, such permanent global Security shall be
surrendered from time to time in accordance with instructions given to the
Trustee and the Common Depositary (which instructions shall be in writing but
need not comply with Section 102 or be accompanied by an Opinion of Counsel) by
the Common Depositary or such other depositary or Common Depositary as shall be
specified in the Company Order with respect thereto to the Trustee, as the
Company's agent for such purpose, to be exchanged, in whole or in part, for
definitive Securities of the same series without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such permanent global
Security, a like aggregate principal amount definitive Securities of the same
series of authorized denominations and of like tenor as the portion of such
permanent global Security to be exchanged which, unless the Securities of the
series are not issuable both as Bearer Securities and as Registered Securities,
as specified as contemplated by Section 301, shall be in the form of Bearer
Securities or Registered Securities, or any combination thereof, as shall be
specified by the beneficial owner thereof; provided, however, that no such
exchanges may occur during a period beginning at the opening of business 15
days before any selection of Securities of that series is to be redeemed and
ending on the relevant Redemption Date; and provided, further, that no Bearer
Security delivered in exchange for a portion of a permanent global Security
shall be mailed or otherwise delivered to any location in the United States.
Promptly following any such exchange in part, such permanent global Security
shall be returned by the Trustee to the Common Depositary or such other
depositary or Common Depositary referred to above in accordance with the
instructions of the Company referred to above.  If a Registered Security is
issued in exchange for any portion of such permanent global Security after the
close of business at the office or agency where such exchange occurs on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such





                                       23
<PAGE>   30
Registered Security, but will be payable on such Interest Payment Date or
proposed date for payment, as the case may be, only to the Person to whom
interest in respect of such portion of such permanent global Security is
payable in accordance with provisions of this Indenture.

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

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

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the
opening of business 15 days before any selection of Securities of that series
to be redeemed and ending at the close of business on (A) if Securities of the
series are issuable only as Registered Securities, the day of the mailing of
the relevant notice of redemption and (B) if Securities of the series are
issuable as Bearer Securities, the day of the first publication of the relevant
notice of redemption, or if Securities of the series are also issuable as
Registered Securities and there is no publication, the mailing of the relevant
notice of redemption, or (ii) to register the transfer of or exchange any
Registered Security so selected for redemption, in whole or in part, except the
unredeemed portion of any Registered Security being redeemed in part, or (iii)
to exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption.

         Notwithstanding the foregoing and except as otherwise specified or
contemplated by Section 301, any Book-Entry Security shall be exchangeable
pursuant to this Section 305 or Sections 304, 906 and 1107 for Securities
registered in the name of, and a transfer of a Book Entry Security of any
series may be registered to, any Person other than the Depository for such
Security or its nominee only if (i) such Depository notifies the Company that
it is unwilling or unable to continue as Depository for such Book-Entry
Security or if at any time such Depository ceases to be a clearing agency
registered under the Securities Exchange Act of 1934, (ii) the Company executes
and delivers to the Trustee a Company Order that such Book-Entry Security shall
be so exchangeable and the transfer thereof so registrable or (iii) there shall
have occurred and be continuing an Event of Default, with respect to the
Securities of such series.  Upon the occurrence in respect of any Book-Entry
Security of any series of any one or more of the conditions specified in clause
(i), (ii) or (iii) of the preceding sentence or such other conditions as may be
specified, such Book-Entry Security may be exchanged for Securities registered
in the names of, and the transfer of such





                                       24
<PAGE>   31
Book-Entry Security may be registered to, such Persons (including Persons other
than the Depository with respect to such series and its nominees) as such
Depository shall direct.  Notwithstanding any other provision of this
Indenture,-any Security authenticated and delivered upon registration of
transfer of, or in exchange for, or in lieu of, any Book-Entry Security shall
also be a Book-Entry Security and shall bear the legend specified in Section
204 except for any Security authenticated and delivered in exchange for, or
upon registration of transfer of, a Book-Entry Security pursuant to the
preceding sentence.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities and Coupons.

         If any mutilated Security or a Security with a mutilated coupon
appertaining thereto is surrendered to the Trustee, the Company 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, with coupons corresponding to the
coupons, if any, appertaining to the surrendered Security.

         If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security or coupon and (ii) such security or indemnity as may be required by
them to save each of them and any agent of either of them harmless, then, in
the absence of notice to the Company or the Trustee that such Security or
coupon has been acquired by a bona fide purchaser, the Company shall execute
and the Trustee shall authenticate and deliver, in lieu of any such destroyed,
lost or stolen Security or in exchange for the Security to which a destroyed,
lost or stolen coupon appertains (with all appurtenant coupons not destroyed,
lost or stolen), a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding, with
coupons corresponding to the coupons, if any, appertaining to such destroyed,
lost or stolen Security or to the Security to which such destroyed, lost or
stolen coupon appertains.

         In case any such mutilated, destroyed, lost or stolen Security or
coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security, pay such Security or coupon;
provided, however, that the principal of and any premium and interest on Bearer
Securities shall, except as other vise provided in Section 1002, be payable
only at an office or agency located outside the United States.

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

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security or
in exchange for a Security to which a destroyed, lost or stolen coupon
appertains, shall constitute an original additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Security and its
coupons, if any, or the destroyed, lost or stolen coupon shall be at any time
enforceable by anyone, and any such new Security and coupons, if any, shall be
entitled to all the benefits of this Indenture equally and





                                       25
<PAGE>   32
proportionately with any and all other Securities of that series and their
coupons, if any, 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 or
coupons.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

         Unless otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest on any Registered 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.  Unless otherwise so provided, at the option of
the Company, payment of interest on any Registered Security may be made by
check mailed on or before the due date to the address of the Person entitled
thereto as such address shall appear in the Security Register.

         Any interest on any Registered 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 Company, at
its election in each case, as provided in clause (1) or (2) below:

                 (1)      The Company may elect to make payment of any
         Defaulted Interest to the Persons in whose names the Registered
         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 Company shall notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each
         Registered Security of such series and the date of the proposed
         payment, and at the same time the Company shall deposit with the
         Trustee an amount of money equal to the aggregate amount proposed to
         be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit prior to the
         date of the proposed payment, such money when deposited to be held in
         trust for the benefit of the Persons entitled to such Defaulted
         Interest as in this Clause provided.  Thereupon the Trustee shall fix
         a Special Record Date for the payment of such Defaulted Interest which
         shall be not more than 15 days and not less than 10 days prior to the
         date of the proposed payment and not less than 10 days after the
         receipt by the Trustee of the notice of the proposed payment.  The
         Trustee shall promptly notify the Company of such Special Record Date
         and, in the name and at the expense of the Company, shall cause notice
         of the proposed payment of such Defaulted Interest and the Special
         Record Date therefor to be mailed, first-class postage prepaid, to
         each Holder of Registered Securities of such series at the address of
         such Holder as it appears in the Security Register, not less than 10
         days prior to such Special Record Date.  Notice of the proposed
         payment of such Defaulted Interest and the Special Record Date
         therefor having been so mailed, such Defaulted Interest shall be paid
         to the Persons in whose names the Registered Securities of such series
         (or their respective Predecessor Securities) are registered





                                       26
<PAGE>   33
         at the close of business on such Special Record Date and shall no
         longer be payable pursuant to the following clause (2).

                 (2)      The Company may make payment of any Defaulted
         Interest on the Registered Securities of any series in any other
         lawful manner not inconsistent with the requirements of any securities
         exchange on which such Securities may be then listed, and upon such
         notice as may be required by such exchange, if, after notice given by
         the Company 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 and Section 305,
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 Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as
the owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 305 and 307) any
interest on such Security and for all other purposes whatsoever, whether or not
such Security be overdue, and neither the Company, the Trustee nor any agent of
the Company or the Trustee shall be affected by notice to the contrary.

         Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery.  The Company, the Trustee and any agent of the Company
or the Trustee may treat the bearer of any Bearer Security and the bearer of
any coupon as the owner of such Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

         Notwithstanding the foregoing, with respect to any Book-Entry
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 a Depository or impair, as between a
Depository and holders of beneficial interests in any Book-Entry Security, the
operation of customary practices governing the exercise of the rights of the
Depository (or its nominee) as Holder of such Book-Entry Security.

SECTION 309.  Cancellation.

         All Securities and coupons 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.  All Registered Securities and matured coupons so
delivered shall be promptly canceled by the Trustee.  All Bearer Securities and
unmatured coupons





                                       27
<PAGE>   34
so delivered shall be held by the Trustee and, upon instruction by a Company
Order, shall be canceled or held for reissuance.  Bearer Securities and
unmatured coupons held for reissuance may be reissued only in replacement of
mutilated, lost, stolen or destroyed Bearer Securities of the same series and
like tenor or the related coupons pursuant to Section 306.  All Bearer
Securities and unmatured coupons held by the Trustee pending such cancellation
or reissuance shall be deemed to be delivered for all purposes of this
Indenture and the Securities.  The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the
Company 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 and
coupons held by the Trustee shall be disposed of in accordance with its
customary practice.

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.

                           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 any right to receive
additional amounts, as provided in Section 1004), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

         (1)     either

                 (A)      all Securities theretofore authenticated and
         delivered and all coupons, if any, appertaining thereto (other than
         (i) coupons appertaining to Bearer Securities surrendered for exchange
         for Registered Securities and maturing after such exchange, whose
         surrender is not required or has been waived as provided in Section
         305, (ii) Securities and coupons which have been destroyed, lost or
         stolen and which have been replaced or paid as provided in Section
         306, (iii) coupons appertaining to Securities called for redemption
         and maturing after the relevant Redemption Date, whose surrender has
         been waived as provided in Section 1106, and (iv) Securities and
         coupons for whose payment money has theretofore been deposited in
         trust or segregated and held in trust by the Company and thereafter
         repaid to the Company or discharged from such trust, as provided in
         Section 1003) have been delivered to the Trustee for cancellation; or

<PAGE>   35
                 (B)      all such Securities and, in the case of (i) or (ii)
         below, any coupons appertaining thereto 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 Company;

         and the Company, 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 an amount sufficient to pay and discharge the
         entire indebtedness on such Securities and coupons not theretofore
         delivered to the Trustee for cancellation, for principal (and premium,
         if any) and any 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 Company has paid or caused to be paid all other sums
payable hereunder by the Company; and

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

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

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, the
coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal and
any premium and interest for whose payment such money has been deposited.

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, rule
or regulation of any administrative or governmental body), unless it is either
inapplicable to a particular series of Securities or it is specifically deleted
or modified in or pursuant to the terms of such series or in the form of
Security of such series:

         Security of that series when it becomes due and payable, and
         continuance of such default for a period of 30 days; or

         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 Company by the Trustee or to

         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; or

                 (5)      the entry by a court having jurisdiction in the
         premises of (A) a decree or order for relief in respect of the Company
         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 Company a bankrupt or insolvent,
         or approving as properly filed a petition seeking reorganization,
         arrangement, adjustment or composition of or in respect of the Company
         under any applicable Federal or State law, or appointing a custodian,

         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

         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 Company in an involuntary case or proceeding under any
         applicable Federal or State bankruptcy, insolvency, reorganization or
         other similar law or 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
         similar official of the Company 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 taking of corporate
         action by the Company in furtherance of any such action; 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 (or, if any of the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified in the terms
thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), 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 that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

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

                          (A)     all overdue 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





                                       31
<PAGE>   38
                          (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 Company 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 Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities and coupons, the whole amount then due and payable
on such Securities and coupons 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 Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company 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 Company 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
and any related coupons by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or ill
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.





                                       32
<PAGE>   39
SECTION 504.  Trustee May File Proofs of Claim.

         In case of any judicial proceeding relative to the Company (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 Holders, vote for the election of a
trustee of 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 or
              Coupons.

         All rights of action and claims under this Indenture or the Securities
or coupons may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or coupons 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 reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities and coupons 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 or coupons, or both as
the case may be, 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; and

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





                                       33
<PAGE>   40
         according to the amounts due and payable on such Securities and
         coupons for principal and any premium and interest, respectively.

         In any case in which Securities are Outstanding that are denominated
in more than one currency and the Trustee is directed to make ratable payments
under this Section to Holders of such Securities, unless otherwise provided
with respect to any series of Securities, the Trustee shall calculate the
amount of such payments as follows:  (i) as of the day the Trustee collects an
amount under this Article, the Trustee shall, as to each Holder of a Security
to whom an amount is due and payable under this Section that is denominated in
a foreign currency, determine that amount in Dollars that would be obtained for
the amount owing such Holder, using the rate of exchange at which in accordance
with normal banking procedures the Trustee could purchase in The City of New
York Dollars with such amount owing; (ii) calculate the sum of all Dollar
amounts determined under (i) and add thereto any amounts due and payable in
Dollars; and (iii) using the individual amounts determined in (i) or any
individual amounts due and payable in Dollars, as the case may be, as a
numerator, and the sum calculated in (ii) as a denominator, calculate as to
each Holder of a Security to whom an amount is owed under this Section the
fraction of the amount collected under this Article payable to such Holder.
Any expenses incurred by the Trustee in actually converting amounts owing
Holders of Securities denominated in a currency other than that in which any
amount is collected under this Article shall be likewise (in accordance with
this paragraph) borne ratably by all Holders of Securities to whom amounts are
payable under this Section.

         To the fullest extent allowed under applicable law, if for the purpose
of obtaining judgment against the Company in any court it is necessary to
convert the sum due in respect of the principal of, or premium, if any, or
interest on, the Securities of any series (the "Required Currency") into a
currency in which a judgment will be rendered (the "Judgment Currency"), the
rate of exchange used shall be the rate at which in accordance with normal
banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the Business Day in the City of
New York next preceding that on which final judgment is given.  Neither the
Company nor the Trustee shall be liable for any shortfall nor shall it benefit
from any windfall in payments to Holders of Securities under this Section
caused by a change in exchange rates between the time the amount of a judgment
against the Company is calculated as above and the time the Trustee converts
the Judgment Currency into the Required Currency to make payments under this
Section to Holders of Securities, but payment of such judgment shall discharge
all amounts owed by the Company on the claim or claims underlying such
judgment.

SECTION 507.  Limitation on Suits.

         No Holder of any Security of any series or any related coupons 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;





                                       34
<PAGE>   41
                 (2)      the Holders of not less than 25% in principal amount
         of the Outstanding Securities of that series shall have made written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing 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 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 or coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of and any premium and
(subject to Sections 305 and 307) any interest on such Security or payment of
such coupon on the Stated Maturity or Maturities expressed in such Security or
coupon (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 of a Security or coupon has instituted
any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities and coupons 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 or coupons in the
last paragraph of Section 306, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders of Securities or coupons is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the





                                       35
<PAGE>   42
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 Security
or coupon 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 of Securities or coupons may
be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders of Securities or coupons, as the case may be.

SECTION 512.  Control by Holders of Securities.

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

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

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

                 (3)      the Trustee shall not be obligated to take any action
         unduly prejudicial to Holders not joining in such direction or
         involving the Trustee in personal liability.

SECTION 513.  Waiver of Past Defaults.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all the Securities of
such series waive any past default hereunder with respect to the Securities of
such series 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 such series affected.





                                       36
<PAGE>   43
         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 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 of such suit, and may assess costs
against any such party litigant, in the manner and to the extent provided in
the Trust Indenture Act; provided that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the
Company.

SECTION 515.  Waiver of Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever
claim to take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (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 SIX
                                  THE TRUSTEE

SECTION 601.  Certain Duties and Responsibilities.

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





                                       37
<PAGE>   44
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 rely and shall be protected in acting
         or refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties;

                 (2)      any request or direction of the Company mentioned
         herein shall be sufficiently evidenced by a Company Request or Company
         Order 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 Officers'
         Certificate;

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

                 (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 to examine the books, records and premises of the Company,
         personally or by agent or attorney; 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) and in any coupons shall be taken as
the statements of the Company, and the Trustee or any Authenticating Agent
assumes no responsibility for their correctness.  The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons.  The Trustee or any Authenticating Agent shall not be
accountable for the use or application by the Company 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 Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and coupons and,
subject to Sections 608 and 613, may otherwise deal with the Company 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 with the Company.

SECTION 607.  Compensation and Reimbursement.

         The Company agrees

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

                 (3)      to indemnify the Trustee and each predecessor Trustee
         for, and to hold it harmless against, any loss, liability or expense
         incurred without negligence or bad faith on its part, arising out of
         or in connection with the acceptance or administration of the trust or
         trusts hereunder, including the costs and expenses of defending itself
         against any claim or liability in connection with the exercise or
         performance of any of its powers or duties hereunder.





                                       39
<PAGE>   46
         As security for the performance of the obligations of the Company
under this Section the Trustee shall have a lien prior to the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the benefit of the Holders of particular Securities.

SECTION 608.  Disqualification; 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.

SECTION 609.  Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall 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 exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000, subject to supervision or examination by Federal or
State authority.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.  If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article.  No obligor upon any
Security issued under this Indenture or a person directly or indirectly
controlling, controlled by or under common control with such obligor shall
serve as Trustee under this Indenture.

SECTION 610.  Resignation and Removal; Appointment of Successor.

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

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

         (d)     If at any time:

                 (1)      the Trustee shall fail to comply with Section 608
         after written request therefor by the Company or by any Holder of a
         Security 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
         Company or by any such Holder, or

                 (3)      the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent or a receiver of the Trustee or of
         its property shall be appointed or a 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
         case, (i) the Company by a Board Resolution may remove the Trustee
         with respect to all Securities, or (ii) subject to Section 514, any
         Holder of a Security 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.

         (e)     If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of the Trustee for any cause,
with respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee 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 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 Company 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
Company.  If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders of Securities of
such series and accepted appointment in the manner required by Section 611, any
Holder of a Security 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.  Such court may thereupon, after such notice, if any, as it may deem
proper, appoint a successor Trustee.

         (f)     The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
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.

         (a)     In case of the appointment hereunder of a successor Trustee
with respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee, with like effect as
if originally named Trustee hereunder; but on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all
the rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.  Any Trustee ceasing to act shall,
nevertheless, retain a prior lien upon all property or funds held or collected
by such Trustee to secure any amounts then due it pursuant to the provisions of
Section 607.

         (b)     In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each 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 as 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 rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates; but, on request of the
Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

         (c)     Upon request of any successor Trustee, the Company 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 paragraph (a) or (b) of this Section, as the case may be.





                                       42
<PAGE>   49
         (d)     No successor Trustee shall accept its appointment unless at
the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article.

SECTION 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 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 Company.

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

SECTION 614.  Appointment of Authenticating Agent.

         The Trustee may, by an instrument in writing, appoint an
Authenticating Agent or Agents with respect to one or more series of Securities
which may be authorized to act on behalf of the Trustee to authenticate
Securities of such series issued upon original issue or 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.  Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia (or, if Bearer Securities, organized and doing business
under the laws of the country in which the Bearer Securities are eligible),
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 (or, if Bearer Securities, an
authority of the country in which the Bearer Securities are eligible).  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





                                       43
<PAGE>   50
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 the corporate agency or
corporate trust business of such Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or such Authenticating Agent.

         An Authenticating Agent may, and if it shall cease to be eligible
shall, resign at any time by giving written notice thereof to the Trustee and
to the Company.  The Trustee may at any time terminate the agency of an
Authenticating Agent by giving written notice thereof to such Authenticating
Agent and to the Company.  Upon receiving such notice of resignation or upon
such termination, or in case at any time such Authenticating Agent shall cease
to be eligible in accordance with the provisions of this Section, the Trustee
may appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall mail written notice of such appointment by first-class mail,
postage prepaid, to all Holders of Registered Securities, if any, of the series
with respect to which such Authenticating Agent will serve, as their names and
addresses appear in the Security Register.  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 Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payment, subject to the
provisions of Section 607.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have been 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.

                                             By:
                                                --------------------------------
                                                     As Authenticating Agent
                                             
                                             By:
                                                --------------------------------
                                                     Authorized Officer"

         If all the Securities of a series may not be originally issued at one
time, and if the Company has an Affiliate eligible to be appointed as an
Authenticating Agent hereunder or the Trustee does not have an office capable
of authenticating Securities upon original issuance located in a Place of
Payment where the Company wishes to have Securities of such series
authenticated upon original issuance, the Trustee, if so requested by the
Company in writing (which writing need not comply with Section 102 and need not
be accompanied by an Opinion of Counsel), shall appoint in accordance with this
Section an Authenticating Agent (which, if so requested by the Company, shall
be such Affiliate of the Company) having an office in a Place of Payment
designated by the Company with respect to such series of Securities.

an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities of such series and any related coupons 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, or
         reduce the principal amount thereof or the rate of interest thereon or
         any premium payable upon the redemption thereof, or change the
         Redemption Date thereof, or change any obligation of the Company to
         pay additional amounts pursuant to Section 1004 (except as
         contemplated by Section 801 (1) and permitted by Section 901(1)), or
         reduce the amount of the principal of an Original Issue Discount
         Security that 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 change any right of redemption, purchase or
         repayment by the Company at the option of the Holder, 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 reduce the
         requirements of Section 1404 for quorum or voting, or

                 (3)      change any obligation of the Company to maintain an
         office or agency in the places and for the purposes specified in
         Section 1002, or

                 (4)      modify any of the provisions of this Section, Section
         513 or Section 1008 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 of a
         Security or coupon with respect to changes in the references to "the
         Trustee" and concomitant changes in this Section and Section 1008 or
         the deletion of this provision, in accordance with the requirements of
         Sections 611(b) 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





                                       49
<PAGE>   56
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 of Securities 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 Indenture for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered
hereunder and of any coupons appertaining thereto 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 as then in effect.

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 Company
shall so determine, new Securities of any series so modified as to conform, in
the opinion of the Trustee and the Company, to any such supplemental indenture
may be prepared and executed by the Company and authenticated and delivered by
the Trustee in exchange for Outstanding Securities of such series and of like
tenor.

                                   COVENANTS

SECTION 1001.  Payment of Principal, Premium and Interest.

         The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any
premium and interest on the Securities of that series in accordance with the
terms of the Securities, any coupons appertaining thereto and this Indenture.
Unless otherwise specified as contemplated by Section 301 with respect to any
series of Securities, any interest due on Bearer Securities on or before
Maturity shall be payable only upon presentation and surrender of the several
coupons for such interest installments as are evidenced thereby as they
severally mature.

SECTION 1002.  Maintenance of Office or Agency.

         If Securities of a series are issuable only as Registered Securities,
the Company will maintain in each Place of Payment for such series 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 Company in
respect of the Securities of that series and this Indenture may be served.  If
Securities of a series are issuable as Bearer Securities, the Company will
maintain (A) in the Borough of Manhattan, The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment, where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may
be surrendered for exchange, where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served
and where Bearer Securities of that series and related coupons may be presented
or surrendered for payment in the circumstances described in the following
paragraph (and not otherwise), (B) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series which is located
outside the United States, an office or agency where Securities of that series
and related coupons may be presented and surrendered for payment (including
payment of any additional amounts payable on Securities of that series pursuant
to Section 1004); provided, however, that if the Securities of that series are
listed on The International Stock Exchange of the United Kingdom and the
Republic of Ireland Limited, the Luxembourg Stock Exchange or any other stock
exchange located outside the United States and such stock exchange shall so
require, the Company will maintain a Paying Agent for the Securities of that
series in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Securities of that series are
listed on such exchange, and (C) subject to any laws or regulations applicable
thereto, in a Place of Payment for that series located outside the United
States an office or agency where any Registered Securities of that series may
be surrendered for registration of transfer, where Securities of that series
may be surrendered for exchange and where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be
served.  The Company will give prompt written notice to the Trustee and prompt
notices to the Holders as provided in Section 106 of the location, and any
change in the location, of any such office or agency.  If at any time the
Company shall fail to maintain any such required office or agency in respect of
any series of Securities or shall fail to furnish the Trustee with the address
thereof, such presentations and





                                       51
<PAGE>   58
surrenders of Securities of that series may be made and notices and demands may
be made or served at the Corporate Trust Office of the Trustee, except that
Bearer Securities of that series and the related coupons may be presented and
surrendered for payment (including payment of any additional amounts payable on
Bearer Securities of that series pursuant to Section 1004) at any Paying Agent
for such series located outside the United States, and the Company hereby
appoints the same as its agents to receive such respective presentations,
surrenders, notices and demands.

         No payment of principal, premium or interest on Bearer Securities
shall be made at any office or agency of the Company in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States provided, however, that, if
the Securities of a series are denominated and payable in Dollars payment of
principal of and any premium and interest on any Bearer Security (including any
additional amounts payable on Securities of such series pursuant to Section
1004) shall be made at the office of the Company's Paying Agent in the Borough
of Manhattan, The City of New York, if (but only if) payment in Dollars of the
full amount of such principal, premium, interest or additional amounts, as the
case may be, at all offices or agencies outside the United States maintained
for the purpose by the Company in accordance with this Indenture is illegal or
effectively precluded by exchange controls or other similar restrictions.

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

SECTION 1003.  Money for Securities Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of and 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 or interest so
becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure to so act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
and any premium or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay the principal and any premium or interest
so becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure to so act.





                                       52
<PAGE>   59
         The Company will cause each Paying Agent for any series of Securities
(other than the Company or the Trustee) to execute and deliver to the Trustee
an instrument in which such Paying Agent shall agree with the Trustee, subject
to the provisions of this Section, that such Paying Agent will (i) comply with
the provisions of the Trust Indenture Act applicable to it as a Paying Agent
and (ii) during the continuance of any default by the Company (or any other
obligor upon the Securities of that series) in the making of any payment in
respect of the Securities of that series, and 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 Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Company or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the
Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of and any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal and any premium or interest has become due and payable
shall be paid to the Company on Company Request (unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
law), or (if then held by the Company) shall be discharged from such trust; and
the Holder of such Security or any coupon appertaining thereto shall (unless
otherwise required by mandatory provisions of applicable escheat or abandoned
or unclaimed property law) thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in an Authorized
Newspaper in each Place of Payment, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

SECTION 1004.  Additional Amounts.

         If the Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Security of such series or
any coupon appertaining thereto additional amounts as provided therein.
Whenever in this Indenture there is mentioned, in any context, the payment of
the principal of or any premium or interest on, or in respect of, any Security
of any series or payment of any related coupon or the net proceeds received on
the sale or exchange of any Security of any series, such mention shall be
deemed to include mention of the payment of additional amounts provided for in
this Section to the extent that, in such context, additional amounts are, were
or would be payable in respect thereof pursuant to the provisions of this
Section and express mention of the payment of additional amounts (if
applicable) in any provisions hereof shall not be construed as excluding
additional amounts in those provisions hereof where such express mention is not
made.





                                       53
<PAGE>   60
         If the Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal and
any premium is made), and at least 10 days prior to each date of payment of
principal and any premium or interest if there has been any change with respect
to the matters set forth in the below-mentioned Officers' Certificate, the
Company will furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series or any related
coupons who are United States Aliens without withholding for or on account of
any tax, assessment or other governmental charge described in the Securities of
that series.  If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be
withheld on such payments to such Holders of Securities or coupons and the
Company will pay to the Trustee or such Paying Agent the additional amounts
required by this Section.  The Company covenants to indemnify the Trustee and
any Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officers' Certificate furnished pursuant to this Section.

SECTION 1005.  Purchase of Securities by Company or Subsidiary.

         If and so long as the Securities of a series are listed on The
International Stock Exchange of the United Kingdom and the Republic of Ireland
Limited and such stock exchange shall so require, the Company will not, and
will not permit any of its Subsidiaries to, purchase any Securities of that
series by private treaty at a price (exclusive of expenses and accrued
interest) which exceeds 120% of the mean of the nominal quotations of the
Securities of that series as shown in The Stock Exchange Daily Official List
for the last trading day preceding the date of purchase.

SECTION 1006.  Statement by Officer as to Default.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, a brief
certificate from the principal executive officer, principal financial officer
or principal accounting officer as to his or her knowledge of the Company's
compliance with all conditions and covenants under this Indenture.  For
purposes of this Section 1007, such compliance shall be determined without
regard to any period of grace or requirement of notice under this Indenture.

SECTION 1007.  Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 1005 with respect to the
Securities of any series if before the time for such compliance the Holders of
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





                                       54
<PAGE>   61
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.

                                 ARTICLE ELEVEN
                            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 Securities of any
series) in accordance with this Article.

SECTION 1102.  Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution.  In the case of any redemption at the election
of the Company of less than all the Securities of any series, the Company
shall, at least 45 days prior to the Redemption Date fixed by the Company
(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 of
such series to be redeemed.  In the case of any redemption of Securities (i)
prior to the expiration of any restriction on such redemption provided in the
terms of such Securities or elsewhere in this Indenture, or (ii) pursuant to an
election of the Company which is subject to a condition specified in the terms
of such Securities, the Company shall furnish the Trustee with an Officers'
Certificate evidencing compliance with such restriction or condition.

SECTION 1103.  Selection of Securities to Be Redeemed.

         If less than all the Securities of any series are to be redeemed
(unless all of the Securities of such series of a specified tenor are to be
redeemed) the particular Securities to be redeemed shall be selected not more
than 45 days prior to the Redemption Date by the Company or the Trustee, from
the Outstanding Securities of such series not previously called for redemption,
by such method as the Company or the Trustee shall deem fair and appropriate
and which may provide for the selection for redemption of portions (equal to
the minimum authorized denomination for Securities of that series or any
integral multiple thereof) of the principal amount of Registered Securities of
such series of a denomination larger than the minimum authorized denomination
for Securities of that series or of the principal amount of global Securities
of such series.  If less than all of the Securities of such series and of a
specified tenor are to be redeemed, the particular Securities to be redeemed
shall be selected not more than 45 days prior to the Redemption Date by the
Company or the Trustee, from the Outstanding Securities of such series and
specified tenor not previously called for redemption in accordance with the
preceding sentence.

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





                                       55
<PAGE>   62
         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 in the manner provided in Section
106 to the Holders of Securities to be redeemed not less than 30 for more than
45 days prior to the Redemption Date.

         All notices of redemption shall state:

                 (1)      the Redemption Date,

                 (2)      the Redemption Price,

                 (3)      if less than all the Outstanding Securities of any
         series are to be redeemed, the identification (and, in the case of
         partial redemption of any Securities, the principal amounts) of the
         particular Securities to be redeemed, and that on and after the
         Redemption Date, upon surrender of the Securities, new Securities of
         such series in principal amount equal to the unredeemed part thereof
         will be issued,

                 (4)      that on the Redemption Date the Redemption Price 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 such Securities, together
         in the case of Bearer Securities with all coupons appertaining
         thereto, if any, maturing after the Redemption Date, are to be
         surrendered for payment of the Redemption Price, and

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

A notice of redemption published as contemplated by Section 106 need not
identify particular Registered Securities to be redeemed.

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

SECTION 1105.  Deposit of Redemption Price.

         On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and





                                       56
<PAGE>   63
(except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that date.

SECTION 1106.  Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest and the coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void.  Upon surrender of any such Security for
redemption in accordance with said notice, together with all coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest to
the Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States (except
as otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of coupons
for such interest, and provided, further, that, unless otherwise specified as
contemplated by Section 301, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save
each of them and any Paying Agent harmless.  If thereafter the Holder of such
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by coupons shall be payable only
at an office or agency located outside the United States (except as otherwise
provided in Section 1002) and, unless otherwise specified as contemplated by
Section 301, only upon presentation and surrender of those coupons.

         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 Registered Security which is to be redeemed only in part shall be
surrendered at a Place of Payment thereof (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by,





                                       57
<PAGE>   64
the Holder thereof or his attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Registered 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 TWELVE
                                 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 a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment".  If provided for by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 1202.  Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

SECTION 1202.  Satisfaction of Sinking Fund Payments with Securities.

         The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption), together in the case of any Bearer
Securities of such series with all unmatured coupons appertaining thereto, and
(2) may apply as a credit Securities of a series which have been redeemed
either at the election of the Company 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 the Securities of such series
required to be made pursuant to the terms of such Securities as provided for by
the terms of such series; provided that such Securities have not been
previously so credited.  Such Securities shall be received and credited for
such purpose by the Trustee at the Redemption Price specified in such
Securities for redemption through operation of the sinking fund and the amount
of such sinking fund payment shall be reduced accordingly.

SECTION 1203.  Redemption of Securities for Sinking Fund.

         Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee a Company Order
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
credited.  Not less than 30 days before each such sinking fund

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 Company in the manner provided in Section 1104.  Such
notice having been duly given, the redemption of such Securities shall be made

Securities of any series upon compliance with the conditions set forth below in
this Article Thirteen.

SECTION 1302.  Defeasance and Discharge.

         Upon the Company's exercise of the option provided in Section 1301
applicable to this Section, the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities of any series

"defeasance").  For this purpose, such defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by
the Outstanding Securities of such series and to have satisfied all its other
obligations under the Securities of such series and this Indenture insofar as
the Securities of such series are concerned (and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging the same), except
for the following which shall survive until otherwise terminated or discharged
hereunder:  (A) the rights of Holders of the Securities of such series 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 the Securities of such series when such payments are

Subject to compliance with this Article Thirteen, the Company may exercise its
option under this Section 1302 notwithstanding the prior exercise of its option
under Section 1303.

SECTION 1303.  Covenant Defeasance.

         Upon the Company's exercise of the option provided in Section 1301
applicable to this Section, (i) the Company shall be released from its
obligations with respect to the Securities of such series under Sections 801
and 1005, and (ii) the occurrence of an event specified in Sections 501(3) or
(4) shall not be deemed to be an Event of Default on and after the date the
conditions set forth below are satisfied (hereinafter, "covenant defeasance"),
but the remainder of this Indenture and such Securities shall be unaffected
thereby.  For this purpose, such covenant defeasance means that the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section or clause whether
directly or indirectly by reason of any reference elsewhere herein to any such
Section or clause or by reason of any reference in any such Section or clause
to any other provision herein or in any such





                                       59
<PAGE>   66
Section or clause 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 application of either Section
1302 or Section 1303 to the then Outstanding Securities of any series:

                 (1)      The Company shall irrevocably have deposited or
         caused to be deposited with the Trustee (or another trustee satisfying
         the requirements of Section 609 who shall agree to comply with the
         provisions of this Article Thirteen applicable to it) as trust funds
         in trust for the purpose of making the following payments specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of the Securities of such series, (A) money in an amount, or
         (B) U.S. Government Obligations which through the scheduled payment of
         principal and interest in respect thereof in accordance with their
         terms will provide, not later than one day before the due date of any
         payment, money in an amount, or (C) a combination thereof, sufficient,
         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 (or other qualifying trustee) to pay and discharge, the
         principal of (and premium, if any) and each installment of interest on
         the Securities and any coupons pertaining thereto on the Stated
         Maturity of such principal (and premium, if any) or installment of
         interest in accordance with the terms of this Indenture and of the
         Securities of such series.  For this purpose, "U.S. Government
         Obligations" means securities that are (x) direct obligations of the
         United States of America for the payment of which its full faith and
         credit is pledged or (y) obligations of a Person controlled or
         supervised by and acting as an agency or instrumentality of the United
         States of America the payment of which is unconditionally guaranteed
         as a full faith and credit obligation by the United States of America,
         which, in either case, are not callable or redeemable at the option of
         the issuer thereof, and shall also include a depository receipt issued
         by a bank (as defined in Section 3(a)(2) of the Securities Act of
         1933, as custodian with respect to any such U.S. Government Obligation
         or a specific payment of principal of or interest on any such U.S.
         Government Obligation held by such custodian for the account of the
         holder of such depository receipt, 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 depository receipt from any
         amount received by the custodian in respect of the U.S. Government
         Obligation or the specific payment of principal of or interest on the
         U.S. Government Obligation evidenced by such depository receipt.

                 (2)      In the case of an election under Section 1302, the
         Company shall have delivered to the Trustee an Opinion of Counsel
         stating that (x) the Company has received from, or there has been
         published by, the Internal Revenue Service a ruling, or (y) since the
         date of this Indenture there has been a change in the applicable
         Federal income tax law, in either case to the effect that, and based
         thereon such opinion shall confirm that, the Holders of the
         Outstanding Securities of such series will not recognize income, gain
         or loss for





                                       60
<PAGE>   67
         Federal income tax purposes as a result of such deposit, defeasance
         and discharge and will be subject to Federal income tax on the same
         amounts, in the same manner and at the same times as would have been
         the case if such deposit, defeasance and discharge had not occurred.

                 (3)      In the case of an election under Section 1303, the
         Company shall have delivered to the Trustee an Opinion of Counsel to
         the effect that the Holders of the Outstanding Securities of such
         series will not recognize gain or loss for Federal income tax purposes
         as a result of such deposit and covenant defeasance and will be
         subject to Federal income tax on the same amount, in the same manner
         and at the same times as would have been the case if such deposit and
         covenant defeasance had not occurred.

                 (4)      No Event of Default or event which with notice or
         lapse of time or both would become an Event of Default with respect to
         the Securities of such series shall have occurred and be continuing on
         the date of such deposit or, insofar as subsections 501(5) and (6) are
         concerned, at any time during the period ending on the 121st day after
         the date of such deposit (it being understood that this condition
         shall not be deemed satisfied until the expiration of such period).

                 (5)      Such defeasance or covenant defeasance shall not
         cause the Trustee to       have a conflicting interest within the
         meaning of the Trust Indenture Act with respect to any securities of
         the Company.

                 (6)      Such defeasance or covenant defeasance shall not
         result in a breach or violation of, or constitute a default under, any
         other agreement or instrument to which the Company is a party or by
         which it is bound.

                 (7)      The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for relating to either the defeasance
         under Section 1302 or the covenant defeasance under Section 1303 (as
         the case may be) have been complied with.

                 (8)      Such defeasance or covenant defeasance shall not
         result in the trust arising from such deposit constituting an
         investment company as defined in the Investment Company Act of 1940,
         or such trust shall be qualified under such Act or exempt from
         regulation thereunder.

SECTION 1305.  Deposited Money and U.S. Government Obligations to Be Held in
               Trust; Other Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee -- collectively, for
purposes of this Section 1305, the "Trustee") pursuant to Section 1304 in
respect of the Securities of such series shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities of such
series and this Indenture, to the





                                       61
<PAGE>   68
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
the Securities of such series, of all sums due and to become due thereon in
respect of principal (and premium, if any) and interest, but such money need
not be segregated from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. 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 the Outstanding Securities.

         Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1304 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 an equivalent defeasance or covenant
defeasance.

SECTION 1306.  Reinstatement.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 1302 or 1303 by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under this Indenture and the
Securities of such series shall be revived and reinstated as though no deposit
had occurred pursuant to this Article Thirteen until such time as the Trustee
or Paying Agent is permitted to apply all such money in accordance with Section
1302 or 1303; provided, however, that if the Company makes any payment of
principal of or any premium or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of the Securities of such series to receive such payment from
the money held by the Trustee or the Paying Agent.

of Holders of Securities of such series may be called at any time and from time

Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified
in Section 1401, by written request setting forth in reasonable detail the
action proposed to be taken at the meeting, and the Trustee shall not have made
the first publication of the notice of such meeting within 21 days after
receipt of such request or shall not thereafter proceed to cause the meeting to

such series in the amount above specified, as the case may be, may determine

London for such meeting and may call such meeting for such purposes by giving

Holders of Securities of such series.  In the absence of a quorum within 30
minutes of the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10

         Except as limited by Section 512 or the proviso to the first paragraph
of Section 902, any resolution presented to a meeting (or adjourned meeting
duly reconvened at which a quorum is present as aforesaid) may be adopted by
the affirmative vote of the Holders of a majority in principal amount of the

                                       63
<PAGE>   70
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action which this Indenture expressly provides may be made,
given or taken by the Holders of a specified percentage, which is less than a

specified percentage in principal amount of the Outstanding Securities of that
series.

         To the extent consistent with the terms of this Indenture, any
resolution passed or decision taken at any meeting of Holders of Securities of
any series duly held in accordance with this Section shall be binding on all
the Holders of Securities of such series and the related coupons, whether or
not present or represented at the meeting.

SECTION 1405.  Determination of Voting Rights; Conduct and Adjournment of
               Meetings.

         (a)     Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities of a series in regard to proof of the holding
of Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate.  Except as otherwise permitted or required by any such
regulations, the holding of Securities shall be proved in the manner specified
in Section 104 and the appointment of any proxy shall be proved in the manner
specified in Section 104 or by having the signature of the Person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized
by Section 104 to certify to the holding of Bearer Securities.  Such
regulations may provide that written instruments appointing proxies, regular on
their face, may be presumed valid and genuine without the proof specified in
Section 104 or other proof.

         (b)     The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1402(b), in
which case the Company or the Holders of Securities of the series calling the
meeting, as the case may be, shall in like manner appoint a temporary chairman.
A permanent chairman and a permanent secretary of the meeting shall be elected
by vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

         (c)     At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding.  The chairman of the meeting shall have no right to
vote, except as a Holder of a Security of such series or proxy.

<PAGE>   71
         (d)     Any meeting of Holders of Securities of any series duly called
pursuant to Section 1402 at which a quorum is present may be adjourned from

Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting.  A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1402 and, if
applicable, Section 1404.  Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting.  Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

         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

         This is to certify that as of the date hereof, and except as set forth

capacity, such certificate or affidavit shall also constitute sufficient proof

action, or to vote on any action, authorized or permitted to be given or taken
by Holders of Securities of such series.  If not set by the Company prior to
the first solicitation of a Holder of Securities of such series made by any
Person in respect of any such action, or, in the case of any such vote, prior
to such vote, the record date for any such action or vote shall be the 30th day
(or, if later, the date of the most recent list of Holders required to be
provided pursuant to Section 701) prior to such first solicitation or vote, as

such series on such date (or their duly designated proxies) shall be entitled
to give or take, or vote on, the relevant action.

     (d)     The principal amount and serial numbers of Registered Securities
held by any Person, and the date of holding the same, shall be proved by the

by any Person, and the date of holding the same, may be proved by the
production of such Bearer Securities or by a certificate executed, as
depositary, by any trust company, bank, banker or other depositary, wherever
situated, if such certificate shall be deemed by the Trustee to be
satisfactory, showing that at the date therein mentioned such Person had on
deposit with such depositary, or exhibited to it, the Bearer Securities therein
described; or such facts may be proved by the certificate or affidavit of the
Person holding such Bearer Securities, if such certificate or affidavit is
deemed by the Trustee to be satisfactory.  The Trustee and the Company may
assume that such ownership of any Bearer Security continues until (1) another
certificate or affidavit bearing a later date issued in respect of the same
Bearer Security is produced, or (2) such Bearer Security is produced to the
Trustee by some other Person, or (3) such Bearer Security is surrendered in
exchange for a Registered Security, or (4) such Bearer Security is no longer
Outstanding.  The principal amount and serial numbers of Bearer Securities held
by any Person, and the date of holding the same, may also be proved in any
other manner which the Trustee deems sufficient.

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

     (g)     Without limiting the foregoing, a Holder entitled hereunder to
give or 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 different part of such principal amount.

     In case by reason of the suspension of regular mail service or by reason

every purpose hereunder.  In any case where notice to Holders of Registered
Securities is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder of a Registered
Security shall affect the sufficiency of such notice with respect to other
Holders of Registered Securities or the sufficiency of any notice to Holders of
Bearer Securities given as provided herein.

     In case by the reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such





                                       11

Holders for every purpose hereunder.  Neither the failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect
in any notice so published, shall affect the sufficiency of any notice to
Holders of Registered Securities given as provided herein.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

SECTION 107.  Language of Notices, Etc.

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

SECTION 108.  Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act that is required under such Act to be a part of and
govern this Indenture, the latter provision shall control.  If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

SECTION 109.  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 110.  Successors and Assigns.

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

SECTION 111.  Separability Clause.

     In case any provision in this Indenture or the Securities or coupons 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 112.  Benefits of Indenture.

     Nothing in this Indenture or the Securities or coupons, express or
implied, shall give to any Person, other than the parties hereto, their
successors hereunder, the holders of Senior Indebtedness  and the Holders of
Securities and coupons, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

SECTION 113.  Governing Law.

     This Indenture and the Securities and coupons shall be governed by and
construed in accordance with the laws of the State of New York.

SECTION 114.  Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security or the last date for conversion of any Security shall
not be a Business Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture or of the Securities or coupons other than a
provision in the Securities of any series 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 at such Place of Payment on such date
and such conversion need not be made at such Place of Payment on such date, but
may be made on the next succeeding Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date or Redemption
Date, or at the Stated Maturity, or on the last date for conversion, as the
case may be, provided that no interest shall accrue on the amount so payable
for the period from and after such date.

                                  ARTICLE TWO
                                 SECURITY FORMS

SECTION 201.  Forms Generally.

     The Registered Securities, if any, of each series and the Bearer
Securities, if any, of each series and related coupons shall be in
substantially the form (including temporary or permanent global form) as shall
be established by or pursuant to a Board Resolution or in one or more
indentures supplemental hereto, in each case with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by
this Indenture, and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as may be
required to comply with law, or with the rules of any securities exchange or to
conform to general, usage, all as may, consistently herewith, be determined by
the officers executing such Securities or coupons, as evidenced by their
execution of the Securities or coupons.  If temporary Securities of any series
are issued in global form as permitted by Section 304, the form thereof shall
be established as provided in the preceding sentence.  A copy of the Board
Resolution establishing the forms of Securities or coupons of any series (or
any such temporary global Security) shall be certified by the Secretary or an
Assistant Secretary of the Company and delivered to the Trustee at or prior to
the delivery of the Company Order contemplated by Section 303 for the
authentication and delivery of such Securities (or any such temporary global
Security) or coupons.

     Unless otherwise specified as contemplated by Section 301, Securities in
bearer form shall have interest coupons attached.

     The definitive Securities and coupons, if any, shall be printed,
lithographed or engraved on steel engraved borders or may be produced in any
other manner, all as determined by the officers executing such Securities, as
evidenced by their execution of such Securities or coupons.

<PAGE>   21
SECTION 202.  Form of Trustee's Certificate of Authentication.

     The Trustee's certificate of authentication shall be in substantially the
following form:

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


                                        ----------------------------------------
                                                     as Trustee


                                        By:   
                                           -------------------------------------
                                                     Authorized Officer."


SECTION 203.  Securities in Global Form.

     If Securities of a series are issuable in global form, as specified as
contemplated by Section 301, then, notwithstanding clause (10) of Section 301
and the provisions of Section 302, any such Security shall represent such of
the Outstanding Securities of such series as shall be specified therein and may
provide that it shall represent the aggregate amount of Outstanding Securities
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities represented thereby may be reduced to reflect exchanges.  Any
endorsement of a Security in global form to reflect the amount, or any increase
or decrease in the amount, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner and upon instructions given by such
Person or Persons as shall be specified therein or in the Company Order to be
delivered to the Trustee pursuant to Section 303 or Section 304.  Subject to
the provisions of Section 303 and, if applicable, Section 304, the Trustee
shall deliver and redeliver any Security in permanent global form in the manner
and upon instructions given by the Person or Persons specified therein or in
the applicable Company Order.  If a Company Order pursuant to Section 303 or
304 has been, or simultaneously is, delivered, any instructions by the Company
with respect to endorsement or delivery or redelivery of a Security in global
form shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

     The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

     Notwithstanding the provisions of Sections 201 and 307, unless otherwise
specified as contemplated by Section 301, payment of principal of and any
premium and interest on any Security in permanent global form shall be made to
the Person or Persons specified therein.

SECTION 204.  Form of Legend for Book-Entry Securities.

     Any Book-Entry Security authenticated and delivered hereunder shall bear a
legend in substantially the following form:

     "This Security is a Book-Entry Security within the meaning of the
Indenture hereinafter referred to and is registered in the name of a Depository
or a nominee of a Depository.  This Security is exchangeable for Securities
registered in the name of a Person other than the Depository or its nominee
only in the limited circumstances described in the Indenture, and no transfer
of this Security (other than a transfer of this Security as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository) may be registered except
in such limited circumstances."

                                 ARTICLE THREE

shall rank equally and pari passu with each other series, but all Securities
issued hereunder shall be subordinate and junior in right of payment, to the
extent and in the manner set forth in Article Sixteen, to all Senior
Indebtedness.  There shall be established in or pursuant to a Board Resolution
and, subject to Section 303, set forth, or determined in the manner provided,
in an Officers' Certificate, or established in one or more indentures
supplemental hereto, prior to the issuance of Securities of any series:

             (1)      the title of the Securities of the series (which shall
     distinguish the Securities of the series from all other Securities);

             (2)      any limit upon the aggregate principal amount of the
     Securities of the series which may be authenticated and delivered under
     this Indenture (except for Securities authenticated and delivered upon
     registration of transfer of, or in exchange for, or in lieu of, other
     Securities of the series pursuant to Section 304, 305, 306, 906 or 1107
     and except for any Securities which, pursuant to Section 303, are deemed
     never to have been authenticated and delivered hereunder);

             (3)      whether Securities of the series are to be issuable as
     Registered Securities, Bearer Securities or both, whether any Securities
     of the series are to be issuable initially in temporary global form and
     whether any Securities of the series are to be issuable in permanent
     global form with or without coupons and, if so, whether beneficial owners
     of interests in any such permanent global Security may exchange such
     interests for Securities of such series and of like tenor of any
     authorized form and denomination and the circumstances under which any
     such exchanges may occur, if other than in the manner provided in Section
     305;

             (4)      the Person to whom any interest on any Registered
     Security of the series shall be payable, if other than 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, the
     manner in which, or the Person to whom, any interest on any Bearer
     Security of the series shall be payable, if otherwise than upon
     presentation and surrender of the coupons appertaining thereto as they
     severally mature and the extent to which, or the manner in which, any
     interest payable on a temporary global Security on an Interest Payment
     Date will be paid if other than in the manner provided in Section 304;

     the Interest Payment Dates on which any such interest shall be payable,
     and the Regular Record Date for any interest payable on any Registered
     Securities on any Interest Payment Date and whether, and under what
     circumstances, additional amounts with respect to such Securities shall be
     payable as set forth in Section 1001;

             (7)      the place or places where, subject to the provisions of
     Section 1002, the principal of and any premium and interest on Securities

     may be surrendered for registration of transfer, Securities of the series
     may be surrendered for exchange or conversion and notices and demands to

     redemption, sinking fund or analogous provisions or at the option of a
     Holder thereof and the period or periods within which, the price or prices
     at which and the terms and conditions upon which Securities of the series

     such obligation;

             (10)     the denominations in which any Registered Securities of

             (12)     if the amount of payments of principal of and any premium

     to Section 502;

             (14)     if the principal of and any premium or interest on the

             (15)     whether the Securities of the series shall be issued upon
     original issuance in whole or in part in the form of one or more
     Book-Entry Securities and, in such case, (a) the Depository with respect
     to such Book-Entry Security or Securities; and (b) the circumstances under
     which any such Book-Entry Security may be exchanged for Securities
     registered in the name of, and any transfer of such Book-Entry Security

     if other than as set forth in Section 305;

             (16)     if either or both of the provisions of Section 1302 or
     1303 are applicable to the Securities of such series and any additional
     means of discharge pursuant to Section 1302 or 1303 and any additional
     conditions to the provisions of Section 1302 or 1303;

             (17)     any other Events of Default or covenants with respect to

             (18)     whether the Securities of the series will be convertible
     into Common Stock (or cash in lieu thereof) and, if so, the terms and

     different from those set forth in Section 1504, the conversion period and
     other provisions in addition to or in lieu of those set forth herein;

             (19)     any subordination provisions with respect to the
     Securities of such series in addition to or in lieu of those set forth in
     Article Sixteen hereof; and

             (20)     any other terms of the series (which terms shall not be
     inconsistent with the provisions of this Indenture except as permitted by
     Section 901(5)).

     All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in
the case of Registered Securities, 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 Officers' Certificate referred to above or in any such indenture
supplemental hereto.





                                       17
<PAGE>   25
     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 Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

SECTION 302.  Denominations.

     Unless otherwise provided as contemplated by Section 301 with respect to
any series of Securities, any Registered Securities of a series shall be
issuable in denominations of $1,000 and any integral multiple thereof and any
Bearer Securities of a series shall be issuable in the denomination of $5,000.

SECTION 303.  Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, a Vice Chairman of the Board, its President, its Treasurer or its
Chief Financial Officer, under its corporate seal reproduced thereon attested
by its Secretary or one of its Assistant Secretaries.  The signature of any of
these officers on the Securities may be manual or facsimile.  Coupons shall
bear the facsimile signature of the Treasurer or any Assistant Treasurer of the
Company.

     Securities and coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, 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 Company may deliver Securities of any series, together with any
coupons appertaining thereto, executed by the Company 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,
unless otherwise provided with respect to such series, in connection with its
original issuance, no Bearer Security shall be mailed or otherwise delivered to
any location in the United States; and provided, further, that, unless
otherwise provided with respect to such series, a Bearer Security may be
delivered in connection with its original issuance only if the Person entitled
to receive such Bearer Security shall have furnished a certificate in the form
set forth in Exhibit A to this Indenture, dated no earlier than the
Certification Date.  If any Security shall be represented by a permanent global
Bearer Security, then, for purposes of this Section and Section 304, the
notation of a beneficial owner's interest therein upon original issuance of
such Security or upon exchange of a portion of a temporary global Security
shall be deemed to be delivery in connection with its original issuance of such
beneficial owner's interest in such permanent global Security.  Except as
permitted by Section 306, the Trustee shall not authenticate and deliver any
Bearer Security unless all appurtenant coupons for interest then matured have
been detached and canceled.

     In authenticating 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:





                                       18
<PAGE>   26
             (a)      that the forms of such Securities and coupons established
     by or pursuant to a Board Resolution as contemplated by Section 201 have
     been established in conformity with the provisions of this Indenture;

             (b)      if the terms of such Securities and any coupons have been
     established by or pursuant to a Board Resolution as permitted by Section
     301, that such terms have been established in conformity with the
     provisions of this Indenture; and

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

Such Opinion of Counsel shall also cover such other matters as the Trustee may
reasonably request.

     The Trustee shall not be required to authenticate such Securities the
forms or terms of which have been established by or pursuant to a Board
Resolution 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 two preceding
paragraphs, if all Securities of a series are not to be originally issued at
one time, it shall not be necessary to deliver the Officers' Certificate
otherwise required pursuant to Section 301 or the Company Order and Opinion of
Counsel otherwise required pursuant to such preceding paragraphs at or prior to
the time of authentication of each Security of such series if such documents
are delivered at or prior to the authentication upon issuance of the first
Security of such series to be issued.

     After the original issuance of the first Security of such series to be
issued, any separate request by the Company that the Trustee authenticate
Securities of such series for original issuance will be deemed to be a
certification by the Company (which, subject to Section 601, the Trustee shall
be fully protected in relying on) that it is in compliance with all conditions
precedent provided for in this Indenture relating to the authentication and
delivery of such Securities.

     Each Registered Security shall be dated the date of its authentication;
and each Bearer Security shall be dated as of the date of original issuance of
the first Security of such series to be issued.

     No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on
such Security, or the Security to which such coupon appertains, a certificate
of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder.  Notwithstanding the foregoing, if any
Security shall have been authenticated and delivered hereunder but never issued
and sold by the Company, and the Company shall deliver





                                       19
<PAGE>   27
such Security to the Trustee for cancellation as provided in Section 309
together with a written statement (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) stating that such Security
has never been issued and sold by the Company, 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
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued, in registered
form or, if authorized, in bearer form with one or more coupons or without
coupons, 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.  In the case of any series
issuable as Bearer Securities, such temporary Securities may be in global form.
A temporary Bearer Security shall be delivered only in compliance with the
conditions set forth in Section 303.

     Except in the case of temporary Securities in global form (which shall be
exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company 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 Company maintained pursuant to Section 1002 in a Place
of Payment for such series for the purpose of exchanges of Securities of such
series without charge to the Holder.  Upon surrender for cancellation of any
one or more temporary Securities of any series (accompanied by any unmatured
coupons appertaining thereto) the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like aggregate principal amount
of definitive Securities of the same series and of like tenor of authorized
denominations; provided, however, that no definitive Bearer Security shall be
issued in exchange for a temporary Registered Security.

     If temporary Securities of any series are issued in global form, any such
temporary global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the
"Common Depositary"), for the benefit of Euro-clear and CEDEL S.A., for credit
to the respective accounts of the beneficial owners of such Securities (or to
such other accounts as they may direct).

     Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security of a series (the "Exchange Date"), the Company shall deliver to the
Trustee definitive Securities of that series in aggregate principal amount
equal to the principal amount of such temporary global Security, executed by
the Company.  On or after the Exchange Date such temporary global Security
shall be surrendered by the Common Depositary to the Trustee, as the Company's
agent for such purpose, to be exchanged, in whole or from time to time in part,
for definitive Securities of that series without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary global
Security, a like





                                       20
<PAGE>   28
aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such temporary
global Security to be exchanged; provided, however, that, unless otherwise
specified in such temporary global Security, upon such presentation by the
Common Depositary, such temporary global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by
Euro-clear as to the portion of such temporary global Security held for its
account then to be exchanged and a certificate dated the Exchange Date or a
subsequent date and signed by CEDEL S.A. as to the portion of such temporary
global Security held for its account then to be exchanged, each in the form set
forth in Exhibit B to this Indenture.  The definitive Securities to be
delivered in exchange for any such temporary global Security shall be in bearer
form, registered form, permanent global bearer form or permanent global
registered form, or any combination thereof, as specified as contemplated by
Section 301, and if any combination thereof is so specified, as requested by
the beneficial owner thereof; provided, however, that no definitive Bearer
Security or permanent global Security shall be delivered in exchange for a
temporary Bearer Security except in compliance with the conditions set forth in
Section 303.

     Unless otherwise specified in the temporary global Security, the interest
of a beneficial owner of Securities of a series in a temporary global Security
shall be exchanged on the Exchange Date for definitive Securities (and where
the form of the definitive Securities is not specified by the Holder for an
interest in a permanent global Security) of the same series and of like tenor
unless, on or prior to the Exchange Date, such beneficial owner has not
delivered to Euro-clear or CEDEL S.A., as the case may be, a certificate in the
form set forth in Exhibit A to this Indenture dated no earlier than the
Certification Date, copies of which certificate shall be available from the
offices of Euro-clear and CEDEL S.A., the Trustee, any Authenticating Agent
appointed for such series of Securities and each Paying Agent and after the
Exchange Date, the interest of a beneficial owner of Securities of a series in
a temporary global Security shall be exchanged for definitive Securities (and
where the form of the definitive Securities is not specified by the Holder for
an interest in a permanent global Security) of the same series and of like
tenor following such beneficial owner's delivery to Euro-clear or CEDEL S.A.,
as the case may be, of a certificate in the form set forth in Exhibit A to this
Indenture dated no earlier than the Certification Date.  Unless otherwise
specified in such temporary global Security, any exchange shall be made free of
charge to the beneficial owners of such temporary global Security, except that
a Person receiving definitive Securities must bear the cost of insurance,
postage, transportation and the like in the event that such Person does not
take delivery of such definitive Securities in person at the offices of
Euro-clear or CEDEL S.A. Definitive Securities in bearer form to be delivered
in exchange for any portion of a temporary global Security shall be delivered
only outside the United States.

     Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 301, interest payable on a temporary global Security
on an Interest Payment Date for Securities of such series shall be payable to
Euro-clear and CEDEL S.A. on such Interest Payment Date upon delivery by
Euro-clear and CEDEL S.A. to the Trustee of a certificate or certificates in
the form set forth in Exhibit B to this Indenture, for credit without further
interest on or after such Interest Payment Date to the respective accounts of
the Persons who are the beneficial owners of such temporary global Security on
such Interest Payment Date and who have each delivered to Euro-clear or CEDEL
S.A., as the case may be, a certificate in the form set forth





                                       21
<PAGE>   29
in Exhibit A to this Indenture.  Any interest so received by Euro-clear and
CEDEL S.A. and not paid as herein provided shall be returned to the Trustee
immediately prior to the expiration of two years after such Interest Payment
Date in order to be repaid to the Company in accordance with Section 1003.

SECTION 305.  Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at an office or agency to be maintained
by the Company in accordance with Section 1002 a register (being the combined
register of the Security Registrar and all transfer agents designated pursuant
to Section 1002 for the purpose of registration of transfer of Securities and
sometimes collectively referred to as the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of each series of Registered Securities and the
registration of transfers of such Registered Securities.  The Trustee shall
serve initially as "Security Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein
provided.

     Upon surrender for registration of transfer of any Registered Security of
any series at the office or agency of the Company maintained pursuant to
Section 1002 for such purpose in a Place of Payment for such series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Registered
Securities of the same series of any authorized denominations and of a like
aggregate principal amount and tenor.

     At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon
surrender of the Securities to be exchanged at any such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.  Unless otherwise
provided with respect to any series of Securities, Bearer Securities may not be
issued in exchange for Registered Securities.

     At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon
surrender of the Bearer Securities to be exchanged at any such office or
agency, with all unmatured coupons and all matured coupons in default thereto
appertaining.  If the Holder of a Bearer Security is unable to produce any such
unmatured coupon or coupons or matured coupon or coupons in default, such
exchange may be effected if the Bearer Securities are accompanied by payment in
funds acceptable to the Company in an amount equal to the face amount of such
missing coupon or coupons, or the surrender of such missing coupon or coupons
may be waived by the Company and the Trustee if there is furnished to them such
security or indemnity as they may require to save each of them and any Paying
Agent harmless.  If thereafter the Holder of such Security shall surrender to
any Paying Agent any such missing coupon in respect of which such a payment
shall have been made, such Holder shall be entitled to receive the amount of
such payment; provided, however, that, except as otherwise provided in Section
1002, interest represented by coupons shall be payable only upon presentation
and surrender of those coupons at an office or agency located outside the
United States.  Notwithstanding the foregoing, in case a Bearer Security





                                       22
<PAGE>   30
of any series is surrendered at any such office or agency in exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at
such office or agency on the related proposed date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the coupon relating
to such Interest Payment Date or proposed date for payment, as the case may be,
and interest or Defaulted Interest, as the case may be, will not be payable on
such Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

     Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be
exchangeable only as provided in this paragraph.  If the beneficial owners of
interests in a permanent global Security are entitled to exchange such
interests for Securities of such series and of like tenor and principal amount
of another authorized form and denomination, as specified as contemplated by
Section 301, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities of that series in an aggregate
principal amount equal to the principal amount of such permanent global
Security, executed by the Company.  On or after the earliest date on which such
interests may be so exchanged, such permanent global Security shall be
surrendered from time to time in accordance with instructions given to the
Trustee and the Common Depositary (which instructions shall be in writing but
need not comply with Section 102 or be accompanied by an Opinion of Counsel) by
the Common Depositary or such other depositary or Common Depositary as shall be
specified in the Company Order with respect thereto to the Trustee, as the
Company's agent for such purpose, to be exchanged, in whole or in part, for
definitive Securities of the same series without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such permanent global
Security, a like aggregate principal amount definitive Securities of the same
series of authorized denominations and of like tenor as the portion of such
permanent global Security to be exchanged which, unless the Securities of the
series are not issuable both as Bearer Securities and as Registered Securities,
as specified as contemplated by Section 301, shall be in the form of Bearer
Securities or Registered Securities, or any combination thereof, as shall be
specified by the beneficial owner thereof; provided, however, that no such
exchanges may occur during a period beginning at the opening of business 15
days before any selection of Securities of that series is to be redeemed and
ending on the relevant Redemption Date; and provided, further, that no Bearer
Security delivered in exchange for a portion of a permanent global Security
shall be mailed or otherwise delivered to any location in the United States.
Promptly following any such exchange in part, such permanent global Security
shall be returned by the Trustee to the Common Depositary or such other
depositary or Common Depositary referred to above in accordance with the
instructions of the Company referred to above.  If a Registered Security is
issued in exchange for any portion of such permanent global Security after the
close of business at the office or agency where such exchange occurs on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record





                                       23
<PAGE>   31
Date and before the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed date
for payment, as the case may be, only to the Person to whom interest in respect
of such portion of such permanent global Security is payable in accordance with
provisions of this Indenture.

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

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

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of
or exchange Securities of any series during a period beginning at the opening
of business 15 days before any selection of Securities of that series to be
redeemed and ending at the close of business on (A) if Securities of the series
are issuable only as Registered Securities, the day of the mailing of the
relevant notice of redemption and (B) if Securities of the series are issuable
as Bearer Securities, the day of the first publication of the relevant notice
of redemption, or if Securities of the series are also issuable as Registered
Securities and there is no publication, the mailing of the relevant notice of
redemption, or (ii) to register the transfer of or exchange any Registered
Security so selected for redemption, in whole or in part, except the unredeemed
portion of any Registered Security being redeemed in part, or (iii) to exchange
any Bearer Security so selected for redemption except that such a Bearer
Security may be exchanged for a Registered Security of that series and like
tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption.

     Notwithstanding the foregoing and except as otherwise specified or
contemplated by Section 301, any Book-Entry Security shall be exchangeable
pursuant to this Section 305 or Sections 304, 906 and 1107 for Securities
registered in the name of, and a transfer of a Book-Entry Security of any
series may be registered to, any Person other than the Depository for such
Security or its nominee only if (i) such Depository notifies the Company that
it is unwilling or unable to continue as Depository for such Book-Entry
Security or if at any time such Depository ceases to be a clearing agency
registered under the Securities Exchange Act of 1934, (ii) the Company executes
and delivers to the Trustee a Company Order that such Book-Entry Security shall
be so exchangeable and the transfer thereof so registrable or (iii) there shall
have occurred and be continuing an Event of Default, with respect to the
Securities of such series.  Upon the occurrence in respect of any





                                       24
<PAGE>   32
Book-Entry Security of any series of any one or more of the conditions
specified in clause (i), (ii) or (iii) of the preceding sentence or such other
conditions as may be specified, such Book-Entry Security may be exchanged for
Securities registered in the names of, and the transfer of such Book-Entry
Security may be registered to, such Persons (including Persons other than the
Depository with respect to such series and its nominees) as such Depository
shall direct.  Notwithstanding any other provision of this Indenture, any
Security authenticated and delivered upon registration of transfer of, or in
exchange for, or in lieu of, any Book-Entry Security shall also be a Book-Entry
Security and shall bear the legend specified in Section 204 except for any
Security authenticated and delivered in exchange for, or upon registration of
transfer of, a Book-Entry Security pursuant to the preceding sentence.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities and Coupons.

     If any mutilated Security or a Security with a mutilated coupon
appertaining thereto is surrendered to the Trustee, the Company 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, with coupons corresponding to the
coupons, if any, appertaining to the surrendered Security.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or coupon
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice
to the Company or the Trustee that such Security or coupon has been acquired by
a bona fide purchaser, the Company shall execute and the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
coupon appertains (with all appurtenant coupons not destroyed, lost or stolen),
a new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with coupons corresponding
to the coupons, if any, appertaining to such destroyed, lost or stolen Security
or to the Security to which such destroyed, lost or stolen coupon appertains.

     In case any such mutilated, destroyed, lost or stolen Security or coupon
has become or is about to become due and payable or is being surrendered for
conversion in full, the Company in its discretion may, instead of issuing a new
Security, pay such Security or coupon or authorize the conversion thereof
(without surrender thereof except in the case of a mutilated Security or
coupon); provided, however, that the principal of and any premium and interest
on Bearer Securities shall, except as otherwise provided in Section 1002, be
payable only at an office or agency located outside the United States.

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





                                       25
<PAGE>   33

     Every new Security of any series with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains,
shall constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security and its coupons, if any,
or the destroyed, lost or stolen coupon shall be at any time enforceable by
anyone, and any such new Security and coupons, if any, shall be entitled to all
the benefits of this Indenture equally and proportionately with any and all
other Securities of that series and their coupons, if any, 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,
payment or conversion of mutilated, destroyed, lost or stolen Securities or
coupons.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

     Unless otherwise provided as contemplated by Section 301 with respect to
any series of Securities, interest on any Registered 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.  Unless otherwise so provided, at the option of the Company,
payment of interest on any Registered Security may be made by check mailed on
or before the due date to the address of the Person entitled thereto as such
address shall appear in the Security Register.

     Any interest on any Registered 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 Company, at its election
in each case, as provided in clause (1) or (2) below:

             (1)      The Company may elect to make payment of any Defaulted
     Interest to the Persons in whose names the Registered 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
     Company shall notify the Trustee in writing of the amount of Defaulted
     Interest proposed to be paid on each Registered Security of such series
     and the date of the proposed payment, and at the same time the Company
     shall deposit with the Trustee an amount of money equal to the aggregate
     amount proposed to be paid in respect of such Defaulted Interest or shall
     make arrangements satisfactory to the Trustee for such deposit prior to
     the date of the proposed payment, such money when deposited to be held in
     trust for the benefit of the Persons entitled to such Defaulted Interest
     as in this Clause provided.  Thereupon the Trustee shall fix a Special
     Record Date for the payment of such Defaulted Interest which shall be not
     more than 15 days and not less than 10 days prior to the date of the
     proposed payment and not less than 10 days after the receipt by the
     Trustee of the notice of the proposed payment.  The Trustee shall promptly
     notify the Company of such Special Record Date and, in the name and





                                       26
<PAGE>   34
     at the expense of the Company, shall cause notice of the proposed payment
     of such Defaulted Interest and the Special Record Date therefor to be
     mailed, first-class postage prepaid, to each Holder of Registered
     Securities of such series at the address of such Holder as it appears in
     the Security Register, not less than 10 days prior to such Special Record
     Date.  Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been so mailed, such Defaulted
     Interest shall be paid to the Persons in whose names the Registered
     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 Company may make payment of any Defaulted Interest on
     the Registered Securities of any series in any other lawful manner not
     inconsistent with the requirements of any securities exchange on which
     such Securities may be then listed, and upon such notice as may be
     required by such exchange, if, after notice given by the Company 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 and Section 305, 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 Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as
the owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 305 and 307) any
interest on such Security and for all other purposes whatsoever, whether or not
such Security be overdue, and neither the Company, the Trustee nor any agent of
the Company or the Trustee shall be affected by notice to the contrary.

     Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery.  The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and the bearer of any
coupon as the owner of such Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

     Notwithstanding the foregoing, with respect to any Book-Entry 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 a Depository or impair, as between a
Depository and holders of beneficial interests in any Book-Entry Security, the
operation





                                       27
<PAGE>   35
of customary practices governing the exercise of the rights of the Depository
(or its nominee) as Holder of such Book-Entry Security.

SECTION 309.  Cancellation.

     All Securities and coupons surrendered for payment, redemption,
registration of transfer, conversion 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.  All Registered Securities and matured
coupons so delivered shall be promptly canceled by the Trustee.  All Bearer
Securities and unmatured coupons so delivered shall be held by the Trustee and,
upon instruction by a Company Order, shall be canceled or held for reissuance.
Bearer Securities and unmatured coupons held for reissuance may be reissued
only in replacement of mutilated, lost, stolen or destroyed Bearer Securities
of the same series and like tenor or the related coupons pursuant to Section
306.  All Bearer Securities and unmatured coupons held by the Trustee pending
such cancellation or reissuance shall be deemed to be delivered for all
purposes of this Indenture and the Securities.  The Company may at any time
deliver to the Trustee for cancellation any Securities previously authenticated
and delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Company 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 and coupons held by the Trustee shall be disposed of in accordance
with its customary practice.

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.

                           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 any right to receive additional
amounts, as provided in Section 1004), and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when





                                       28
<PAGE>   36
     (1)     either

             (A)      all Securities theretofore authenticated and delivered
     and all coupons, if any, appertaining thereto (other than (i) coupons
     appertaining to Bearer Securities surrendered for exchange for Registered
     Securities and maturing after such exchange, whose surrender is not
     required or has been waived as provided in Section 305, (ii) Securities
     and coupons which have been destroyed, lost or stolen and which have been
     replaced, converted or paid as provided in Section 306, (iii) coupons
     appertaining to Securities called for redemption and maturing after the
     relevant Redemption Date, whose surrender has been waived as provided in
     Section 1106, and (iv) Securities and coupons for whose payment money has
     theretofore been deposited in trust or segregated and held in trust by the
     Company and thereafter repaid to the Company or discharged from such
     trust, as provided in Section 1003) have been delivered to the Trustee for
     cancellation; or

             (B)      all such Securities and, in the case of (i) or (ii)
     below, any coupons appertaining thereto 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 Company;

     and the Company, 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 an amount sufficient to pay and discharge the entire indebtedness
     on such Securities and coupons not theretofore delivered to the Trustee
     for cancellation, for principal (and premium, if any) and any 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 Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

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

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to clause





                                       29
<PAGE>   37
(1)(B) of this Section, the obligations of the Trustee under Section 402 and
the last paragraph of Section 1003 shall survive.

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, the coupons
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium
and interest for whose payment such money has been deposited.

                                    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 the provisions of Article Sixteen hereof or by operation of law or
pursuant to any judgment, decree or order, rule or regulation of any
administrative or governmental body), unless it is either inapplicable to a
particular series of Securities or it is specifically deleted or modified in or
pursuant to the terms of such series or in the form of Security of such series:

             (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; or

     and as due by the terms of a Security of that series; or

             (4)      default in the performance, or breach, of any covenant or
     warranty of the Company in this Indenture (other than a covenant or
     warranty a default in whose performance or whose breach is elsewhere in
     this Section specifically dealt with 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 Company by the Trustee or to the Company and the Trustee by the
     Holders of at least 25% in principal amount of the Outstanding Securities
     of that series a written notice specifying such default or breach and
     requiring it to be remedied and stating that such notice is a "Notice of
     Default" hereunder; or

             (5)      the entry by a court having jurisdiction in the premises
     of (A) a decree or order for relief in respect of the Company 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 Company a bankrupt or insolvent, or
     approving as properly filed a petition seeking reorganization,
     arrangement, adjustment or composition of or in respect of the Company
     under any applicable Federal or State law, or appointing a custodian,
     receiver, liquidator, assignee, trustee, sequestrator or other similar
     official of the Company or of any substantial part of its property, or
     ordering the winding up or liquidation of its affairs, and the continuance
     of any such decree or order 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 Company 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 Company in an
     involuntary case or proceeding under any applicable Federal or State
     bankruptcy, insolvency, reorganization or other similar law or 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 similar official of the Company 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 taking of corporate action by
     the Company in furtherance of any such action; 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 (or, if any of the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified in the terms
thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), 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 that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if





                                       31
<PAGE>   39

             (1)      the Company 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

                      (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 Company 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 Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities and coupons, the whole amount then due and payable
on such Securities and coupons 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 Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may





                                       32
<PAGE>   40
enforce the same against the Company 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 Company 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 and any
related coupons by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid
of the exercise of any power granted herein, or to enforce any other proper
remedy.

SECTION 504.  Trustee May File Proofs of Claim.

     In case of any judicial proceeding relative to the Company (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, subject to Article Sixteen hereof,  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 Holders, vote for the election of a trustee
of 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 or
              Coupons.

     All rights of action and claims under this Indenture or the Securities or
coupons may be prosecuted and enforced by the Trustee without the possession of
any of the Securities or coupons 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 reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities and coupons in respect
of which such judgment has been recovered.





                                       33
<PAGE>   41
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 or coupons, or both as
the case may be, 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; and

             SECOND:  Subject to Article Sixteen hereof, to the payment of the
     amounts then due and unpaid for principal of and any premium and interest
     on the Securities and coupons 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 and coupons for principal and any premium and interest,
     respectively.

     In any case in which Securities are Outstanding that are denominated in
more than one currency and the Trustee is directed to make ratable payments
under this Section to Holders of such Securities, unless otherwise provided
with respect to any series of Securities, the Trustee shall calculate the
amount of such payments as follows:  (i) as of the day the Trustee collects an
amount under this Article, the Trustee shall, as to each Holder of a Security
to whom an amount is due and payable under this Section that is denominated in
a foreign currency, determine that amount in Dollars that would be obtained for
the amount owing such Holder, using the rate of exchange at which in accordance
with normal banking procedures the Trustee could purchase in The City of New
York Dollars with such amount owing; (ii) calculate the sum of all Dollar
amounts determined under (i) and add thereto any amounts due and payable in
Dollars; and (iii) using the individual amounts determined in (i) or any
individual amounts due and payable in Dollars, as the case may be, as a
numerator, and the sum calculated in (ii) as a denominator, calculate as to
each Holder of a Security to whom an amount is owed under this Section the
fraction of the amount collected under this Article payable to such Holder.
Any expenses incurred by the Trustee in actually converting amounts owing
Holders of Securities denominated in a currency other than that in which any
amount is collected under this Article shall be likewise (in accordance with
this paragraph) borne ratably by all Holders of Securities to whom amounts are
payable under this Section.

     To the fullest extent allowed under applicable law, if for the purpose of
obtaining judgment against the Company in any court it is necessary to convert
the sum due in respect of the principal of, or premium, if any, or interest on,
the Securities of any series (the "Required Currency") into a currency in which
a judgment will be rendered (the "Judgment Currency"), the rate of exchange
used shall be the rate at which in accordance with normal banking procedures
the Trustee could purchase in The City of New York the Required Currency with
the Judgment Currency on the Business Day in the City of New York next
preceding that on which final judgment is given.  Neither the Company nor the
Trustee shall be liable for any shortfall nor shall it benefit from any
windfall in payments to Holders of Securities under this Section caused by a
change in exchange rates between the time the amount of a judgment against the
Company is calculated as above and the time the Trustee converts





                                       34
<PAGE>   42
the Judgment Currency into the Required Currency to make payments under this
Section to Holders of Securities, but payment of such judgment shall discharge
all amounts owed by the Company on the claim or claims underlying such
judgment.

SECTION 507.  Limitation on Suits.

     No Holder of any Security of any series or any related coupons 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 that series shall have made written request
     to the Trustee to institute proceedings in respect of such Event of
     Default in its own name as Trustee hereunder;

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing 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 such
Holders.

SECTION 508.  Unconditional Right of Holders to Receive Principal, Premium and
              Interest.

     Notwithstanding any other provision in this Indenture (but subject to
Article Sixteen hereof), the Holder of any Security or coupon shall have the
right, which is absolute and unconditional, to receive payment of the principal
of and any premium and (subject to Sections 305 and 307) any interest on such
Security or payment of such coupon on the Stated Maturity or Maturities
expressed in such Security or coupon (or, in the case of redemption, on the
Redemption Date) and, if applicable, to convert such Security as provided in
Article Fifteen and to institute suit for the enforcement of any such payment
or conversion right, and such rights shall not be impaired without the consent
of such Holder.





                                       35
<PAGE>   43
SECTION 509.  Restoration of Rights and Remedies.

     If the Trustee or any Holder of a Security or coupon has instituted any
proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities and coupons 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 or coupons in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders of Securities or coupons is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to
the extent permitted by law, be cumulative and in addition to every other right
and remedy given hereunder or now or hereafter existing at law or in equity or
otherwise.  The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any
other appropriate right or remedy.

SECTION 511.  Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security or
coupon 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 of Securities or coupons may
be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders of Securities or coupons, as the case may be.

SECTION 512.  Control by Holders of Securities.

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

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

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





                                       36
<PAGE>   44
             (3)      the Trustee shall not be obligated to take any action
     unduly prejudicial to Holders not joining in such direction or involving
     the Trustee in personal liability.

SECTION 513.  Waiver of Past Defaults.

     The Holders of a majority in principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all the Securities of
such series waive any past default hereunder with respect to the Securities of
such series 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 such series affected.

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

SECTION 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 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, however,  that neither this Section nor the
Trust Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the
Company.

SECTION 515.  Waiver of Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim
to take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (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.

                                  THE TRUSTEE

SECTION 601.  Certain Duties and Responsibilities.

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act.  Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or 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 rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document believed by it to be genuine and to have been signed or presented
     by the proper party or parties;

             (2)      any request or direction of the Company mentioned herein
     shall be sufficiently evidenced by a Company Request or Company Order 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 Officers' Certificate;





                                       38
<PAGE>   46
             (4)      the Trustee may consult with counsel and the written
     advice of such counsel or any Opinion of Counsel shall be full and
     complete authorization and protection in respect of any action taken,
     suffered or omitted by it hereunder in good faith and in reliance thereon;

             (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 to examine the books, records and
     premises of the Company, personally or by agent or attorney; 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) and in any coupons shall be taken as the
statements of the Company, and the Trustee or any Authenticating Agent assumes
no responsibility for their correctness.  The Trustee makes no representations

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and coupons and,

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 with the Company.

SECTION 607.  Compensation and Reimbursement.

     The Company agrees:

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

             (3)      to indemnify the Trustee and each predecessor Trustee
     for, and to hold it harmless against, any loss, liability or expense
     incurred without negligence or bad faith on its part, arising out of or in
     connection with the acceptance or administration of the trust or trusts
     hereunder, including the costs and expenses of defending itself against
     any claim or liability in connection with the exercise or performance of
     any of its powers or duties hereunder.

     The obligations of the Company under this Section shall not be
subordinated to the payment of Senior Indebtedness pursuant to Article Sixteen
hereof, and as security for the performance of such obligations, the Trustee
shall have a lien prior to the Securities upon all property and funds held or
collected by the Trustee as such, except funds held in trust for the benefit of
the Holders of particular Securities.

SECTION 608.  Disqualification; 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.

SECTION 609.  Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall 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 exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000, subject to supervision or examination by Federal or
State authority.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.  If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article.  No obligor upon any
Security issued under this Indenture or a person directly or indirectly
controlling, controlled by or under common control with such obligor shall
serve as Trustee under this Indenture.

SECTION 610.  Resignation and Removal; Appointment of Successor.

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

     (b)     The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company.  If 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 any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

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

     (d)     If at any time:

             (1)      the Trustee shall fail to comply with Section 608 after
     written request therefor by the Company or by any Holder of a Security 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 Company or
     by any such Holder, or





                                       41
<PAGE>   49
             (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 a 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 case, (i) the
     Company by a Board Resolution may remove the Trustee with respect to all
     Securities, or (ii) subject to Section 514, any Holder of a Security 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.

     (e)     If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of the Trustee for any cause,
with respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee 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 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 Company 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
Company.  If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders of Securities of
such series and accepted appointment in the manner required by Section 611, any
Holder of a Security 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.  Such court may thereupon, after such notice, if any, as it may deem
proper, appoint a successor Trustee.

     (f)     The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
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.

     (a)     In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and





                                       42
<PAGE>   50
duties of the retiring Trustee, with like effect as if originally named Trustee
hereunder; but on the request of the Company or the successor Trustee, such
retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder.  Any Trustee ceasing to act shall, nevertheless, retain a prior lien
upon all property or funds held or collected by such Trustee to secure any
amounts then due it pursuant to the provisions of Section 607.

     (b)     In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each 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
as 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 rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates; but, on request of the Company
or any successor Trustee, such retiring Trustee shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

     (c)     Upon request of any successor Trustee, the Company 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
paragraph (a) or (b) of this Section, as the case may be.

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

SECTION 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 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 Company.

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

SECTION 614.  Appointment of Authenticating Agent.

     The Trustee may, by an instrument in writing, appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which may be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon original issue or 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.  Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia (or, if Bearer
Securities, organized and doing business under the laws of the country in which
the Bearer Securities are eligible), 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 (or, if Bearer Securities, an authority of the country in which the
Bearer Securities are eligible).  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.





                                       44
<PAGE>   52
     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 the corporate agency or
corporate trust business of such Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or such Authenticating Agent.

     An Authenticating Agent may, and if it shall cease to be eligible shall,
resign at any time by giving written notice thereof to the Trustee and to the
Company.  The Trustee may at any time terminate the agency of an Authenticating
Agent by giving written notice thereof to such Authenticating Agent and to the
Company.  Upon receiving such notice of resignation or upon such termination,
or in case at any time such Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the Company and
shall mail written notice of such appointment by first-class mail, postage
prepaid, to all Holders of Registered Securities, if any, of the series with
respect to which such Authenticating Agent will serve, as their names and
addresses appear in the Security Register.  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 Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payment, subject to the provisions
of Section 607.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have been 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.


                                        ----------------------------------------

                                                    As Authenticating Agent


                                        By:
                                           -------------------------------------
                                                    Authorized Officer."

     If all the Securities of a series may not be originally issued at one
time, and if the Company has an Affiliate eligible to be appointed as an
Authenticating Agent hereunder or the Trustee does not have an office capable
of authenticating Securities upon original issuance located in a Place of
Payment where the Company wishes to have Securities of such series
authenticated upon original issuance, the Trustee, if so requested by the
Company in writing (which writing need not comply with Section 102 and need not
be accompanied by an Opinion of Counsel), shall appoint in accordance with this
Section an Authenticating Agent (which, if so requested by the Company, shall
be such Affiliate of the Company) having an office in a Place of Payment
designated by the Company with respect to such series of Securities.

     series and any related coupons 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(b); or

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

indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities of such series and any related coupons 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, or reduce the
     principal amount thereof or the rate of interest thereon or any premium
     payable upon the redemption thereof, or change the Redemption Date
     thereof, or change any obligation of the Company to pay additional amounts
     pursuant to Section 1004 (except as contemplated by Section 801(1) and
     permitted by Section 901(1)), or reduce the amount of the principal of an
     Original Issue Discount Security that 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 change any right of redemption, purchase
     or repayment by the Company at the option of the Holder, or adversely
     affect the right to convert Securities, if applicable, or impair the right
     to institute suit for the enforcement of (x) any such payment on or after
     the Stated Maturity thereof (or, in the case of redemption, on or after
     the Redemption Date) or (y) any conversion right with respect to any
     Security, 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 reduce the requirements of Section 1404
     for quorum or voting, or

             (3)      change any obligation of the Company to maintain an
     office or agency in the places and for the purposes specified in Section
     1002, or

             (4)      modify any of the provisions of this Section, Section 513
     or Section 1008 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 of a Security or coupon with respect to
     changes in the references to "the Trustee" and concomitant changes in this
     Section and Section 1008 or the deletion of this provision, in accordance
     with the requirements of Sections 611(b) 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 of Securities 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 Indenture for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered
hereunder and of any coupons appertaining thereto 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 as then in effect.

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 Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series and of like
tenor.

SECTION 907. Subordination Unimpaired.

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

                                  ARTICLE TEN
                                   COVENANTS

SECTION 1001.  Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any
premium and interest on the Securities of that series in accordance with the
terms of the Securities, any coupons appertaining thereto and this Indenture.
Unless otherwise specified as contemplated by Section 301 with respect to any
series of Securities, any interest due on Bearer Securities on or before
Maturity shall be payable only upon presentation and surrender of the several
coupons for such interest installments as are evidenced thereby as they
severally mature.

SECTION 1002.  Maintenance of Office or Agency.

     If Securities of a series are issuable only as Registered Securities, the
Company will maintain in each Place of Payment for such series an office or
agency where Securities of that series may be presented or surrendered for
payment or, if applicable, for conversion, where Securities of that series may
be surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served.  If Securities of a series are issuable as Bearer
Securities, the Company will maintain (A) in the Borough of Manhattan, The City
of New York, an office or agency where any Registered Securities of that series
may be presented or surrendered for payment or, if applicable, for conversion,
where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered
for exchange, where notices and demands to or upon the Company in respect of
the Securities of that series and this Indenture may be served and where Bearer
Securities of that series and related coupons may be presented or surrendered
for payment in the circumstances described in the following paragraph (and not
otherwise), (B) subject to any laws or regulations applicable thereto, in a
Place of Payment for that series which is located outside the United States, an
office or agency where Securities of that series and related coupons may be
presented and surrendered for payment (including payment of any additional
amounts payable on Securities of that series pursuant to Section 1004) or, if
applicable, for conversion; provided, however, that if the Securities of that
series are listed on The International Stock Exchange of the United Kingdom and
the Republic of Ireland Limited, the Luxembourg Stock Exchange or any other
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Securities of that
series in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Securities of that series are
listed on such exchange, and (C) subject to any laws or regulations applicable





                                       52
<PAGE>   60
thereto, in a Place of Payment for that series located outside the United
States an office or agency where any Registered Securities of that series may
be surrendered for registration of transfer, where Securities of that series
may be surrendered for exchange and where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be
served.  The Company will give prompt written notice to the Trustee and prompt
notices to the Holders as provided in Section 106 of the location, and any
change in the location, of any such office or agency.  If at any time the
Company shall fail to maintain any such required office or agency in respect of
any series of Securities or shall fail to furnish the Trustee with the address
thereof, such presentations and surrenders of Securities of that series may be
made and notices and demands may be made or served at the Corporate Trust
Office of the Trustee, except that Bearer Securities of that series and the
related coupons may be presented and surrendered for payment (including payment
of any additional amounts payable on Bearer Securities of that series pursuant
to Section 1004) or, if applicable, for conversion at any Paying Agent for such
series located outside the United States, and the Company hereby appoints the
same as its agents to receive such respective presentations, surrenders,
notices and demands.

     No payment of principal, premium or interest on Bearer Securities shall be
made at any office or agency of the Company in the United States or by check
mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States, provided, however, that,
if the Securities of a series are denominated and payable in Dollars payment of
principal of and any premium and interest on any Bearer Security (including any
additional amounts payable on Securities of such series pursuant to Section
1004) shall be made at the office of the Company's Paying Agent in the Borough
of Manhattan, The City of New York, if (but only if) payment in Dollars of the
full amount of such principal, premium, interest or additional amounts, as the
case may be, at all offices or agencies outside the United States maintained
for the purpose by the Company in accordance with this Indenture is illegal or
effectively precluded by exchange controls or other similar restrictions.

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

SECTION 1003.  Money for Securities Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of and 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 or interest so
becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure to so act.





                                       53
<PAGE>   61

     Whenever the Company shall have one or more Paying Agents for any series
of Securities, it will, on or prior to each due date of the principal of and
any premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay the principal and any premium or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure to so act.

     The Company will cause each Paying Agent for any series of Securities
(other than the Company or the Trustee) to execute and deliver to the Trustee
an instrument in which such Paying Agent shall agree with the Trustee, subject
to the provisions of this Section, that such Paying Agent will (i) comply with
the provisions of the Trust Indenture Act applicable to it as a Paying Agent
and (ii) during the continuance of any default by the Company (or any other
obligor upon the Securities of that series) in the making of any payment in
respect of the Securities of that series, and 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 Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of and any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal and any premium or interest has become due and payable
shall be paid to the Company on Company Request (unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
law), or (if then held by the Company) shall be discharged from such trust; and
the Holder of such Security or any coupon appertaining thereto shall (unless
otherwise required by mandatory provisions of applicable escheat or abandoned
or unclaimed property law) thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in an Authorized
Newspaper in each Place of Payment, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

SECTION 1004.  Additional Amounts.

     If the Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Security of such series or
any coupon appertaining thereto additional amounts as provided therein.
Whenever in this Indenture there is mentioned, in any context, the





                                       54
<PAGE>   62
payment of the principal of or any premium or interest on, or in respect of,
any Security of any series or payment of any related coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of additional amounts
provided for in this Section to the extent that, in such context, additional
amounts are, were or would be payable in respect thereof pursuant to the
provisions of this Section and express mention of the payment of additional
amounts (if applicable) in any provisions hereof shall not be construed as
excluding additional amounts in those provisions hereof where such express
mention is not made.

     If the Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal and
any premium is made), and at least 10 days prior to each date of payment of
principal and any premium or interest if there has been any change with respect
to the matters set forth in the below-mentioned Officers' Certificate, the
Company will furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series or any related
coupons who are United States Aliens without withholding for or on account of
any tax, assessment or other governmental charge described in the Securities of
that series.  If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be
withheld on such payments to such Holders of Securities or coupons and the
Company will pay to the Trustee or such Paying Agent the additional amounts
required by this Section.  The Company covenants to indemnify the Trustee and
any Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officers' Certificate furnished pursuant to this Section.

SECTION 1005.  Purchase of Securities by Company or Subsidiary.

     If and so long as the Securities of a series are listed on The
International Stock Exchange of the United Kingdom and the Republic of Ireland
Limited and such stock exchange shall so require, the Company will not, and
will not permit any of its Subsidiaries to, purchase any Securities of that
series by private treaty at a price (exclusive of expenses and accrued
interest) which exceeds 120% of the mean of the nominal quotations of the
Securities of that series as shown in The Stock Exchange Daily Official List
for the last trading day preceding the date of purchase.

SECTION 1006. Appointments to Fill Vacancies in Trustee's Office.

     The Company, whenever necessary to avoid or fill a vacancy in the office
of the Trustee, will appoint, in the manner provided in Section 610, a Trustee,
so that there shall at all times be a Trustee hereunder.





                                       55
<PAGE>   63
SECTION 1007.  Statement by Officer as to Default.

     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, a brief
certificate from the principal executive officer, principal financial officer
or principal accounting officer as to his or her knowledge of the Company's
compliance with all conditions and covenants under this Indenture.  For
purposes of this Section 1007, such compliance shall be determined without
regard to any period of grace or requirement of notice under this Indenture.

SECTION 1008.  Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 1005 or any covenant added hereto
pursuant to Section 901(2) (unless otherwise provided in the supplemental
indenture adding such covenant hereto) with respect to the Securities of any
series if before the time for such compliance the Holders of 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 Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

                                 ARTICLE ELEVEN
                            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 Securities of any series) in
accordance with this Article.

SECTION 1102.  Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution.  In the case of any redemption at the election of the
Company of less than all the Securities of any series, the Company shall, at
least 45 days prior to the Redemption Date fixed by the Company (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 of such series
to be redeemed.  In the case of any redemption of Securities (i) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, or (ii) pursuant to an election of
the Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

<PAGE>   64

SECTION 1103.  Selection of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed (unless
all of the Securities of such series of a specified tenor are to be redeemed)
the particular Securities to be redeemed shall be selected not more than 45
days prior to the Redemption Date by the Company or the Trustee, from the
Outstanding Securities of such series not previously called for redemption, by
such method as the Company or the Trustee shall deem fair and appropriate and
which may provide for the selection for redemption of portions (equal to the
minimum authorized denomination for Securities of that series or any integral
multiple thereof) of the principal amount of Registered Securities of such
series of a denomination larger than the minimum authorized denomination for
Securities of that series or of the principal amount of global Securities of
such series.  If less than all of the Securities of such series and of a
specified tenor are to be redeemed, the particular Securities to be redeemed
shall be selected not more than 45 days prior to the Redemption Date by the
Company or the Trustee, from the Outstanding Securities of such series and
specified tenor not previously called for redemption in accordance with the
preceding sentence.

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

     For all purposes of this Indenture, unless the context otherwise 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.
If any Security selected for partial redemption is surrendered for conversion
after such selection, the converted portion of such Security shall be deemed
(so far as may be) to be the portion selected for redemption. Upon any
redemption of less than all the Securities of a series, for purposes of
selection for redemption the Company and the Trustee may treat as Outstanding
Securities surrendered for conversion during the period of 15 days next
preceding the mailing of a notice of redemption, and need not treat as
Outstanding any Security authenticated and delivered during such period in
exchange for the unconverted portion of any Security converted in part during
such period.

SECTION 1104.  Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 106
to the Holders of Securities to be redeemed not less than 30 for more than 45
days prior to the Redemption Date.

     All notices of redemption shall state:

             (1)      the Redemption Date,

             (2)      the Redemption Price,





                                       57
<PAGE>   65
             (3)      if less than all the Outstanding Securities of any series
     are to be redeemed, the identification (and, in the case of partial
     redemption of any Securities, the principal amounts) of the particular
     Securities to be redeemed, and that on and after the Redemption Date, upon
     surrender of the Securities, new Securities of such series in principal
     amount equal to the unredeemed part thereof will be issued,

             (4)      that on the Redemption Date the Redemption Price 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 such Securities, together in
     the case of Bearer Securities with all coupons appertaining thereto, if
     any, maturing after the Redemption Date, are to be surrendered for payment
     of the Redemption Price,

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

             (7)      if applicable, the Conversion Price then in effect and
     the date on which the right to convert the Securities or portions thereof
     to be redeemed will expire.

A notice of redemption published as contemplated by Section 106 need not
identify particular Registered Securities to be redeemed.

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

SECTION 1105.  Deposit of Redemption Price.

     On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date. If any Security called for redemption is
converted pursuant hereto, any money deposited with the Trustee or any Paying
Agent or so segregated and held in trust for the redemption of such Security
shall be paid to the Company upon delivery of a Company Request to the Trustee
or such Paying Agent, or, if then held by the Company, shall be discharged from
such trust.

SECTION 1106.  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest and the coupons for such
interest





                                       58
<PAGE>   66
appertaining to any Bearer Securities so to be redeemed, except to the extent
provided below, shall be void.  Upon surrender of any such Security for
redemption in accordance with said notice, together with all coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest to
the Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States (except
as otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of coupons
for such interest, and provided, further, that, unless otherwise specified as
contemplated by Section 301, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

     If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security
may be paid after deducting from the Redemption Price an amount equal to the
face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless.  If thereafter the Holder of such
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by coupons shall be payable only
at an office or agency located outside the United States (except as otherwise
provided in Section 1002) and, unless otherwise specified as contemplated by
Section 301, only upon presentation and surrender of those coupons.

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

                                 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 a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment".  If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 1202.  Each sinking fund payment shall be applied to the redemption
of Securities of any series as provided for by the terms of Securities of such
series.

SECTION 1202.  Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption), together in the case of any Bearer
Securities of such series with all unmatured coupons appertaining thereto, and
(2) may apply as a credit Securities of a series which have been (x) converted
into Common Stock or (y)  redeemed either at the election of the Company
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 the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series, provided that such Securities have not been previously so credited.
Such Securities shall be received and credited for such purpose by the Trustee
at the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 1203.  Redemption of Securities for Sinking Fund.

     Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee a Company Order
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
credited.  Not less than 30 days before each such sinking fund payment date the
Company or 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 Company 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 1106 and 1107.

SECTION 1301.  Company's Option to Effect Defeasance or Covenant Defeasance.

have either Section 1302 or Section 1303 applied to the Outstanding Securities
of any series upon compliance with the conditions set forth below in this
Article Thirteen.

SECTION 1302.  Defeasance and Discharge.

     Upon the Company's exercise of the option provided in Section 1301
applicable to this Section, the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities of any series
(other than any convertible series) on the date the conditions set forth below
are satisfied (hereinafter, "defeasance").  For this purpose, such defeasance
means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by the Outstanding Securities of such series and to
have satisfied all its other obligations under the Securities of such series
and this Indenture insofar as the Securities of such series are concerned (and
the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder:  (A) the rights of Holders of the
Securities of such series 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 the Securities of such
series when such payments are due, (B) the Company's obligations with respect

this Article Thirteen.  Subject to compliance with this Article Thirteen, the
Company may exercise its option under this Section 1302 notwithstanding the
prior exercise of its option under Section 1303.

SECTION 1303.  Covenant Defeasance.

applicable to this Section, (i) the Company shall be released from its
obligations with respect to the Securities of such series under Sections 801
and 1005 and any covenant added to this Indenture pursuant to Section 901(2)
hereof, and (ii) the occurrence of an event specified in Section 501(4) (with
respect to Sections 801 and 1005 and any covenant added to this Indenture
pursuant to Section 901(2) hereof) shall not be deemed to be an Event of
Default on and after the date the conditions set forth below are satisfied
(hereinafter, "covenant defeasance"), but the remainder of this Indenture and
such Securities shall be unaffected thereby.  For this purpose, such covenant
defeasance means that the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
Section or covenant (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 covenant or by reason of any reference in any such Section
or clause to any other





                                       61
<PAGE>   69
provision herein or in any such Section or clause 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 application of either Section
1302 or Section 1303 to the then Outstanding Securities of any series:

             (1)      The Company shall irrevocably have deposited or caused to
     be deposited with the Trustee (or another trustee satisfying the
     requirements of Section 609 who shall agree to comply with the provisions
     of this Article Thirteen applicable to it) as trust funds in trust for the
     purpose of making the following payments specifically pledged as security
     for, and dedicated solely to, the benefit of the Holders of the Securities
     of such series, (A) money in an amount, or (B) U.S. Government Obligations
     which through the scheduled payment of principal and interest in respect
     thereof in accordance with their terms will provide, not later than one
     day before the due date of any payment, money in an amount, or (C) a
     combination thereof, sufficient, 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 (or other qualifying trustee) to pay
     and discharge, the principal of (and premium, if any) and each installment
     of interest on the Securities and any coupons pertaining thereto on the
     Stated Maturity of such principal (and premium, if any) or installment of
     interest in accordance with the terms of this Indenture and of the
     Securities of such series.  For this purpose, "U.S. Government
     Obligations" means securities that are (x) direct obligations of the
     United States of America for the payment of which its full faith and
     credit is pledged or (y) obligations of a Person controlled or supervised
     by and acting as an agency or instrumentality of the United States of
     America the payment of which is unconditionally guaranteed as a full faith
     and credit obligation by the United States of America, which, in either
     case, are not callable or redeemable at the option of the issuer thereof,
     and shall also include a depository receipt issued by a bank (as defined
     in Section 3(a)(2) of the Securities Act of 1933) as custodian with
     respect to any such U.S. Government Obligation or a specific payment of
     principal of or interest on any such U.S. Government Obligation held by
     such custodian for the account of the holder of such depository receipt,
     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
     depository receipt from any amount received by the custodian in respect of
     the U.S. Government Obligation or the specific payment of principal of or
     interest on the U.S. Government Obligation evidenced by such depository
     receipt.

             (2)      In the case of an election under Section 1302, the
     Company shall have delivered to the Trustee an Opinion of Counsel stating
     that (x) the Company has received from, or there has been published by,
     the Internal Revenue Service a ruling, or (y) since the date of this
     Indenture there has been a change in the applicable Federal income tax
     law, in either case to the effect that, and based thereon such opinion
     shall confirm that, the Holders of the Outstanding Securities of such
     series will not recognize income, gain or loss for





                                       62
<PAGE>   70
     Federal income tax purposes as a result of such deposit, defeasance and
     discharge and will be subject to Federal income tax on the same amounts,
     in the same manner and at the same times as would have been the case if
     such deposit, defeasance and discharge had not occurred.

             (3)      In the case of an election under Section 1303, the
     Company shall have delivered to the Trustee an Opinion of Counsel to the
     effect that the Holders of the Outstanding Securities of such series will
     not recognize gain or loss for Federal income tax purposes as a result of
     such deposit and covenant defeasance and will be subject to Federal income
     tax on the same amount, in the same manner and at the same times as would
     have been the case if such deposit and covenant defeasance had not
     occurred.

             (4)      No Event of Default or event which with notice or lapse
     of time or both would become an Event of Default with respect to the
     Securities of such series shall have occurred and be continuing on the
     date of such deposit or, insofar as subsections 501(5) and (6) are
     concerned, at any time during the period ending on the 121st day after the
     date of such deposit (it being understood that this condition shall not be
     deemed satisfied until the expiration of such period).

             (5)      Such defeasance or covenant defeasance shall not cause
     the Trustee to       have a conflicting interest within the meaning of the
     Trust Indenture Act with respect to any securities of the Company.

             (6)      Such defeasance or covenant defeasance shall not result
     in a breach or violation of, or constitute a default under, any other
     agreement or instrument to which the Company is a party or by which it is
     bound.

             (7)      The Company shall have delivered to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each stating that all
     conditions precedent provided for relating to either the defeasance under
     Section 1302 or the covenant defeasance under Section 1303 (as the case
     may be) have been complied with.

             (8)      Such defeasance or covenant defeasance shall not result
     in the trust arising from such deposit constituting an investment company
     as defined in the Investment Company Act of 1940, or such trust shall be
     qualified under such Act or exempt from regulation thereunder.

SECTION 1305.  Deposited Money and U.S. Government Obligations to Be Held in
               Trust; Other Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee (or other qualifying trustee -- collectively, for purposes of this
Section 1305, the "Trustee") pursuant to Section 1304 in respect of the
Securities of such series shall be held in trust and applied by the





                                       63
<PAGE>   71
Trustee, in accordance with the provisions of such Securities of such series
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of the Securities of such series, of all sums due and
to become due thereon in respect of principal (and premium, if any) and
interest, but such money need not be segregated from other funds except to the
extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. 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 the Outstanding Securities.

     Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1304 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 an equivalent defeasance or covenant
defeasance.

SECTION 1306.  Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 1302 or 1303 by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under this Indenture and the
Securities of such series shall be revived and reinstated as though no deposit
had occurred pursuant to this Article Thirteen until such time as the Trustee
or Paying Agent is permitted to apply all such money in accordance with Section
1302 or 1303; provided, however, that if the Company makes any payment of
principal of or any premium or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of the Securities of such series to receive such payment from
the money held by the Trustee or the Paying Agent.

appropriate.  Except as otherwise permitted or required by any such
regulations, the holding of Securities shall be proved in the manner specified

specified in Section 104 or by having the signature of the Person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized

regulations may provide that written instruments appointing proxies, regular on
their face, may be presumed valid and genuine without the proof specified in
Section 104 or other proof.

temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1402(b), in

Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding.  The chairman of the meeting shall have no right to
vote, except as a Holder of a Security of such series or proxy.

reports in duplicate of all votes cast at the meeting.  A record, at least in

vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and

affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting.  Any record so signed and verified shall be conclusive evidence

<PAGE>   75
SECTION 1502.  Exercise of Conversion Privilege.

     In order to exercise the conversion privilege, the Holder of any Security
to be converted shall surrender such Security to the Conversion Agent at any
time during usual business hours at its office or agency maintained for the
purpose as provided in this Indenture, accompanied by a fully executed written
notice, in substantially the form set forth on the reverse of the Security,
that the Holder elects to convert such Security or a stated portion thereof
constituting a multiple of $1,000 in principal amount, and, if such Security is
surrendered for conversion during the period between the close of business on
any record date for such Security and the opening of business on the related
Interest Payment Date and has not been called for redemption on a Redemption
Date within such period (or on such Interest Payment Date), accompanied also by
payment of an amount equal to the interest payable on such Interest Payment
Date on the portion of the principal amount of the Security being surrendered
for conversion.  Such notice shall also state the name or names (and address)
in which the certificate or certificates for shares of Common Stock shall be
issued (or to whom payment in cash in lieu of Common Stock shall be made).
Securities surrendered for conversion shall (if so required by the Company or
the Conversion Agent) be duly endorsed by, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the Conversion Agent duly executed by, the Holder or his attorney duly
authorized in writing.  As promptly as practicable after the receipt of such
notice and the surrender of such Security as aforesaid, the Company shall,
subject to the provisions of Section 1507, issue and deliver at such office or
agency to such Holder, or on his written order, a certificate or certificates
for the number of full shares of Common Stock issuable on conversion of such
Security in accordance with the provisions of such Security and cash, as
provided in Section 1503, in respect of any fraction of a share of Common Stock
otherwise issuable upon such conversion or, if so provided in a Board
Resolution, Officers' Certificate or executed supplemental indenture referred
to in Sections 201 and 301 by or pursuant to which the form and terms of the
Securities of such series were established, cash in lieu of shares of Common
Stock.  Such conversion shall be at the Conversion Price in effect, and shall
be deemed to have been effected, immediately prior to the close of business on
the date (herein called the "Date of Conversion") on which such notice in
proper form shall have been received by the Conversion Agent and such Security
shall have been surrendered as aforesaid, and the Person or Persons in whose
name or names any certificate or certificates for shares of Common Stock shall
be issuable, if any, upon such conversion shall be deemed to have become on the
Date of Conversion the holder or holders of record of the shares represented
thereby; provided, however, that any such surrender on any date when the stock
transfer books of the Company shall be closed shall constitute the Person or
Persons in whose name or names the certificate or certificates for such shares
are to be issued, if any, as the record holder or holders thereof for all
purposes at the opening of business on the next succeeding day on which such
stock transfer books are open but such conversion shall nevertheless be at the
Conversion Price in effect at the close of business on the date when such
Security shall have been so surrendered with the conversion notice in proper
form.  In the case of conversion of a portion, but less than all, of a
Security, the Company shall execute, and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a Security or
Securities in the aggregate principal amount of the unconverted portion of the
Security surrendered.  Except as otherwise expressly provided in this
Indenture, no payment or adjustment shall be made for interest accrued on any
Security (or portion thereof) converted or for dividends or distributions on
any





                                       68
<PAGE>   76
Common Stock issued upon conversion of any Security.  The right, if any, of a
Holder of any Security to cause the Company to redeem, purchase or repay such
Security shall terminate upon receipt by the Company of any notice of
conversion of such Security.

SECTION 1503.  Fractional Interests.

     No fractions of shares or scrip representing fractions of shares shall be
issued upon conversion of Securities.  If more than one Security shall be
surrendered for conversion at one time by the same Holder, the number of full
shares which shall be issuable upon conversion thereof shall be computed on the
basis of the aggregate principal amount of the Securities so surrendered.  If
any fraction of a share of Common Stock would, except for the provisions of
this Section 1503, be issuable on the conversion of any Security or Securities,
the Company shall make payment in lieu thereof in cash equal to the value of
such fraction computed on the basis of the Last Sale Price of one share of
Common Stock on the most recent Trading Day prior to the Date of Conversion.
"Last Sale Price" on any Trading Day shall mean (i) the closing price regular
way (or, if no closing price is reported the average of the bid and asked
prices) as reported on the New York Stock Exchange Composite Tape, or (ii) if
on such Trading Day the Common Stock is not listed or admitted to trading on
such exchange, the closing price regular way (or, if no closing price is
reported the average of the bid and asked prices) on the principal national
securities exchange on which the Common Stock is listed or admitted to trading,
or (iii) if not listed or admitted to trading on any national securities
exchange on such Trading Day, then the average of the closing bid and asked
prices as reported through the National Association of Securities Dealers, Inc.
on its NASDAQ National Market or other NASDAQ market or through a similar
organization if NASDAQ is no longer reporting information, or (iv) if the
Common Stock is not listed or admitted to trading on any national securities
exchange or quoted on such National Market or other NASDAQ market on such
Trading Day, then the average of the closing bid and asked prices in the
over-the-counter market as furnished by any New York Stock Exchange member firm
selected from time to time by the Company for that purpose or (v) if not quoted
by any such organization on such Trading Day, the fair value of such Common
Stock on such Trading Day, as determined by the Board of Directors.  The term
"Trading Day" shall mean each Monday, Tuesday, Wednesday, Thursday and Friday,
other than any day on which securities are not traded on any of the above
mentioned exchanges or in such markets.

SECTION 1504.  Adjustment of Conversion Price.

     The conversion price or rate (herein called the "Conversion Price") for a
series of Securities shall be as set forth in a Board Resolution, Officers'
Certificate or executed supplemental indenture referred to in Sections 201 and
301 by or pursuant to which the form and terms of the Securities of such series
were established, and, except as otherwise provided therein, shall be subject
to adjustment from time to time as follows:

     (a)     In case the Company shall (1) pay a dividend or make a
distribution in shares of Common Stock on the Common Stock, (2) subdivide its
outstanding shares of Common Stock into a greater number of shares, (3) combine
its outstanding shares of Common Stock into a smaller





                                       69
<PAGE>   77
number of shares or (4) issue by reclassification of its Common Stock any
shares of capital stock of the Company, the Conversion Price in effect
immediately prior to such action shall be adjusted so that the Holder of any
Security thereafter surrendered for conversion shall be entitled to receive the
number of shares of Common Stock or other capital stock of the Company which he
would have owned immediately following such action had such Security been
converted immediately prior thereto.  An adjustment made pursuant to this
subsection (a) shall become effective immediately, except as provided in
subsection (e) below, after the record date in the case of a dividend or
distribution and shall become effective immediately after the effective date in
the case of a subdivision, combination or reclassification.  If as a result of
an adjustment made pursuant to this subsection (a), the Holder of any Security
thereafter surrendered for conversion shall become entitled to receive shares
of two or more classes of capital stock (including shares of Common Stock and
other capital stock) of the Company, the Board of Directors (whose
determination shall be conclusive and shall be described in a statement filed
with the Trustee) shall determine the allocation of the adjusted Conversion
Price between or among shares of such classes of capital stock or shares of
Common Stock and other capital stock.

     (b)     In case the Company shall issue rights or warrants to all holders
of Common Stock entitling them (for a period not exceeding 45 days from the
date of such issuance) to subscribe for or purchase shares of Common Stock at a
price per share less than the current market price per share (as determined
pursuant to subsection (d) below) of the Common Stock on the record date
mentioned below, the Conversion Price shall be adjusted to a price, computed to
the nearest cent, so that the same shall equal the price determined by
multiplying;

             (1)      the Conversion Price in effect immediately prior to the
     date of issuance of such rights or warrants by a fraction, of which

             (2)      the numerator shall be (A) the number of shares of Common
     Stock outstanding on the date of issuance of such rights or warrants,
     immediately prior to such issuance, plus (B) the number of shares which
     the aggregate offering price of the total number of shares so offered for
     subscription or purchase would purchase at such current market price
     (determined by multiplying such total number of shares by the exercise
     price of such rights or warrants and dividing the product so obtained by
     such current market price), and of which

             (3)      the denominator shall be (A) the number of shares of
     Common Stock outstanding on the date of issuance of such rights or
     warrants, immediately prior to such issuance, plus (B) the number of
     additional shares of Common Stock which are so offered for subscription or
     purchase.

Such adjustment shall become effective immediately, except as provided in
subsection (e) below, after the record date for the determination of holders
entitled to receive such rights or warrants.





                                       70
<PAGE>   78
     (c)     In case the Company shall distribute to substantially all holders
of Common Stock evidences of indebtedness, equity securities (including equity
interests in the Company's Subsidiaries) other than Common Stock, or other
assets (other than cash dividends paid out of surplus of the Company), or shall
distribute to substantially all holders of Common Stock rights or warrants to
subscribe for securities (other than those referred to in subsection (b) above)
then in each such case the Conversion Price shall be adjusted so that the same
shall equal the price determined by multiplying the Conversion Price in effect
immediately prior to the date of such distribution by a fraction of which the
numerator shall be the current market price per share (determined as provided
in subsection (d) below) of the Common Stock on the record date mentioned below
less the then fair market value (as determined by the Board of Directors, whose
determination shall, if made in good faith, be conclusive evidence of such fair
market value) of the portion of the assets so distributed or of such
subscription rights or warrants applicable to one share of Common Stock, and of
which the denominator shall be such current market price per share of the
Common Stock.  Such adjustment shall become effective immediately, except as
provided in subsection (e) below, after the record date for the determination
of stockholders entitled to receive such distribution.

     (d)     For the purposes of any computation under subsections (b) and (c)
above, the current market price per share of Common Stock on any date shall be
deemed to be the average of the Last Sale Prices for the 30 consecutive Trading
Days commencing 45 Trading Days before the date in question.

     (e)     In any case in which this Section 1504 shall require that an
adjustment be made immediately following a record date, the Company may elect
to defer the effectiveness of such adjustment (but in no event until a date
later than the effective time of the event giving rise to such adjustment), in
which case the Company shall, with respect to any Security converted after such
record date and before such adjustment shall have become effective, (i) defer
paying any cash payment pursuant to Section 1503 or issuing to the Holder of
such Security the number of shares of Common Stock and other capital stock of
the Company issuable upon such conversion in excess of the number of shares of
Common Stock and other capital stock of the Company issuable thereupon only on
the basis of the Conversion Price prior to adjustment and (ii), not later than
five Business Days after such adjustment shall have become effective, pay to
such Holder the appropriate cash payment pursuant to Section 1503 and issue to
such Holder the additional shares of Common Stock and other capital stock of
the Company issuable on such conversion.

     (f)     No adjustment in the Conversion Price shall be required unless
such adjustment would require an increase or decrease of at least 1% of the
Conversion Price; provided, however, that any adjustments which by reason of
this subsection (f) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment and, provided, further, that
adjustment shall be required and made in accordance with the provisions of this
Article Fifteen (other than this subsection (f)) not later than such time as
may be required in order to preserve the tax-free nature of a distribution to
the holders of Securities or Common Stock.  All calculations under this Article
Fifteen shall be made to the nearest cent or to the nearest one-hundredth of a
share, as the case may be.





                                       71
<PAGE>   79
     (g)     Whenever the Conversion Price is adjusted as herein provided, the
Company shall promptly (i) file with the Trustee and each Conversion Agent an
Officers' Certificate setting forth the Conversion Price after such adjustment
and setting forth a brief statement of the facts requiring such adjustment,
which certificate shall be conclusive evidence of the correctness of such
adjustment, and (ii) give or cause to be given a notice of such adjustment to
each Holder of Securities in the manner provided in Section 106.

Anything in this Section 1504 to the contrary notwithstanding, the Company
shall be entitled to make such reductions in the Conversion Price, in addition
to those required by this Section 1504, as it in  its discretion shall
determine to be advisable in order that any stock dividend, subdivision of
shares, distribution of rights or warrants to purchase stock or securities, or
distribution of other assets (other than cash dividends) hereafter made by the
Company to its stockholders shall not be taxable.

SECTION 1505.  Continuation of Conversion Privilege in Case of Merger,
               Consolidation or Sale of Assets.

     If any of the following shall occur, namely:  (a) any consolidation or
merger of the Company as a result of which the holders of Common Stock shall be
entitled to receive stock, other securities or other assets (including cash)
with respect to or in exchange for Common Stock; or (b) any conveyance,
transfer or lease of the properties and assets of the Company substantially as
an entirety to any Person, then the Company, or such successor or purchasing
Person, as the case may be, shall, as a condition precedent to such
consolidation, merger, conveyance, transfer or lease, execute and deliver to
the Trustee a supplemental indenture (which shall conform to the Trust
Indenture Act) providing that the Holder of each convertible Security then
Outstanding shall have the right to convert such Security into the kind and
amount of shares of stock and other securities and property (including cash)
receivable upon or in connection with such consolidation, merger, conveyance,
transfer or lease by a holder of the number of shares of Common Stock issuable
upon conversion of such Security immediately prior to such consolidation,
merger, conveyance, transfer or lease. Such supplemental indenture shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article Fifteen.  If, in
the case of any such consolidation, merger, conveyance, transfer or lease, the
stock or other securities and property (including cash) receivable thereupon or
in connection therewith by a holder of shares of Common Stock includes shares
of stock or other securities and property (including cash) of a Person other
than the successor or purchasing Person, as the case may be, in such
consolidation, merger, conveyance, transfer or lease, then such supplemental
indenture shall also be executed by such other Person and shall contain such
additional provisions to protect the interests of the Holders of the Securities
as the Board of Directors shall reasonably consider necessary by reason of the
foregoing.  The provisions of this Section 1505 shall similarly apply to
successive consolidations, mergers, conveyances, transfer or leases.

     Notice of the execution of each such supplemental indenture shall be given
to each Holder of Securities in the manner provided in Section 106.





                                       72
<PAGE>   80
     Neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any
such supplemental indenture relating either to the kind or amount of shares of
stock or other securities or property (including cash) receivable by Holders of
Securities upon the conversion of their Securities after any such
consolidation, merger, conveyance, transfer or lease or to any adjustment to be
made with respect thereto, but, subject to the provisions of Sections 601 and
603, may accept as conclusive evidence of the correctness of any such
provision, and shall be protected in relying upon, the Officers' Certificate
(which the Company shall be obligated to file with the Trustee prior the
execution of any such supplemental indenture) with respect thereto.

SECTION 1506.  Notice of Certain Events.

     If:

             (a)      the Company shall declare a dividend (or any other
     distribution) payable to the holders of Common Stock otherwise than in
     cash; or

             (b)      the Company shall authorize the granting to all holders
     of Common Stock of rights to subscribe for or purchase any shares of stock
     of any class or of any other rights; or

             (c)      the Company shall authorize any reclassification or
     change of the Common Stock (other than a subdivision or combination of its
     outstanding shares of Common Stock), or any consolidation or merger to
     which the Company is a party and for which approval of any stockholders of
     the Company is required, or the conveyance, transfer or lease of the
     properties and assets of the Company substantially as an entirety; or

             (d)      there shall be authorized or ordered any voluntary or
     involuntary dissolution, liquidation or winding-up of the Company;

then, the Company shall cause to be filed at the office or agency maintained
for the purpose of conversion of the Securities as provided in Section 1002,
and shall cause to be given to each Holder of Securities, in the manner
provided in Section 106, at least 20 days before the date hereinafter specified
(or the earlier of the dates hereinafter specified, in the event that more than
one date is specified), a notice stating the date on which (1) a record is
expected to be taken for the purpose of such dividend, distribution or rights,
or if a record is not to be taken, the date as of which the holders of Common
Stock of record to be entitled to such dividend, distribution or rights are to
be determined, or (2) such reclassification, change, consolidation, merger,
conveyance, transfer or lease, dissolution, liquidation or winding-up is
expected to become effective and the date, if any is to be fixed, as of which
it is expected that holders of Common Stock of record shall be entitled to
exchange their shares of Common Stock for securities or other property
deliverable upon such reclassification, change, consolidation, merger,
conveyance, transfer or lease, dissolution, liquidation or winding-up.





                                       73
<PAGE>   81
SECTION 1507.  Taxes on Conversion.

     The Company will pay any and all documentary, stamp or similar taxes
payable to the United States of America or any political subdivision or taxing
authority thereof or therein in respect of the issue or delivery of shares of
Common Stock on conversion of Securities pursuant thereto; provided, however,
that the Company shall not be required to pay any tax which may be payable in
respect of any transfer involved in the issue or delivery of shares of Common
Stock in a name other than that of the Holder of the Securities to be converted
(or payment of cash in lieu thereof to a Person other than such Holder) and no
such issue or delivery (or payment) shall be made unless and until the Person
requesting such issue or delivery (or payment) has paid to the Company the
amount of any such tax or has established, to the satisfaction of the Company,
that such tax has been paid. The Company extends no protection with respect to
any other taxes imposed in connection with conversion of Securities.

SECTION 1508.  Company to Provide Stock.

     The Company shall reserve, free from preemptive rights, out of its
authorized but unissued shares, sufficient shares to provide for the conversion
of convertible Securities from time to time as such Securities are presented
for conversion, provided, however, that nothing contained herein shall be
construed to preclude the Company from satisfying its obligations in respect of
the conversion of Securities by delivery of repurchased shares of Common Stock
which are held in the treasury of the Company.

     If any shares of Common Stock to be reserved for the purpose of conversion
of Securities hereunder require registration with or approval of any
governmental authority under any Federal or State law before such shares may be
validly issued or delivered upon conversion, then the Company covenants that it
will in good faith and as expeditiously as possible endeavor to secure such
registration or approval, as the case may be; provided, however, that nothing
in this Section 1508 shall be deemed to affect in any way the obligations of
the Company to convert Securities into Common Stock as provided in this Article
Fifteen.

     Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the Common Stock, the
Company will take all corporate action which may, in the opinion of counsel, be
necessary in order that the Company may validly and legally issue fully paid
and non-assessable shares of Common Stock at such adjusted Conversion Price.

     The Company covenants that all shares of Common Stock which may be issued
upon conversion of Securities will upon issue be fully paid and non-assessable
by the Company and free of preemptive rights.





                                       74
<PAGE>   82
SECTION 1509.  Disclaimer of Responsibility for Certain Matters.

     Neither the Trustee, any Conversion Agent nor any agent of either shall at
any time be under any duty or responsibility to any Holder of Securities to
determine whether any facts exist which may require any adjustment of the
Conversion Price, or with respect to the Officers' Certificate referred to in
Section 1504(g), or with respect to the nature or extent of any such adjustment
when made, or with respect to the method employed, or herein or in any
supplemental indenture provided to be employed, in making the same. Neither the
Trustee, any Conversion Agent nor any agent of either shall be accountable with
respect to the validity or value (or the kind or amount) of any shares of
Common Stock, or of any securities or property (including cash), which may at
any time be issued or delivered upon the conversion of any Security, and
neither the Trustee, any Conversion Agent nor any agent of either makes any
representation with respect thereto. Neither the Trustee, any Conversion Agent
nor any agent of either shall be responsible for any failure of the Company to
issue, register the transfer of or deliver any shares of Common Stock or stock
certificates or other securities or property (including cash) upon the
surrender of any Security for the purpose of conversion or, subject to Sections
601 and 603, to comply with any of the covenants of the Company contained in
this Article Fifteen.

SECTION 1510.  Return of Funds Deposited for Redemption of Converted Securities.

     Any funds which at any time shall have been deposited by the Company or on
its behalf with the Trustee or any Paying Agent for the purpose of paying the
principal of and interest, if any, on any of the Securities and which shall not
be required for such purposes because of the conversion of such Securities, as
provided in this Indenture, shall forthwith after such conversion be repaid to
the Company by the Trustee or such Paying Agent.

                                ARTICLE SIXTEEN
                                 SUBORDINATION

SECTION 1601.  Securities Subordinated to Senior Indebtedness.

     The Company covenants and agrees that anything in this Indenture to the
contrary notwithstanding, the indebtedness evidenced by the Securities of each
series is subordinate and junior in right of payment to all Senior Indebtedness
to the extent provided herein or, if so provided in a Board Resolution,
Officers' Certificate or executed supplemental indenture referred to in
Sections 201 and 301 by or pursuant to which the form and terms of the
Securities of such series were established, as and to the extent provided by
the terms of the Securities of such series, and each Holder of Securities of
each series, by his acceptance thereof, likewise covenants and agrees to the
subordination herein or therein provided and shall be bound by the provisions
hereof or thereof.

     Subject to Section 1604, if the Company shall default in the payment of
any principal of or premium or interest on any Senior Indebtedness when the
same becomes due and payable, whether at Stated Maturity or at a date fixed for
redemption or by declaration of acceleration or otherwise, then, upon written
notice of such default to the Company by the holders of such Senior
Indebtedness





                                       75
<PAGE>   83
or any trustee therefor, unless and until such default shall have been cured or
waived or shall have ceased to exist, no direct or indirect payment (in cash,
property, securities, by set-off or otherwise) shall be made or agreed to be
made on account of the principal of or any premium or interest on any of the
Securities, or in respect of any redemption, retirement, purchase or other
acquisition of any of the Securities other than those made in capital stock of
the Company (or cash in lieu of fractional shares thereof) pursuant to Article
Fifteen or otherwise made in capital stock of the Company (or cash in lieu of
fractional shares thereof).

     If (a) without the consent of the Company a court having jurisdiction
shall enter an order for relief with respect to the Company under the
Bankruptcy Code or without the consent of the Company a court having
jurisdiction shall enter a judgment, order or decree adjudging the Company a
bankrupt or insolvent, or enter an order for relief for reorganization,
arrangement, adjustment or composition of or in respect of the Company under
the Bankruptcy Code or applicable state insolvency law, or (b) the Company
shall institute proceedings for entry of an order for relief with respect to
the Company under the Bankruptcy Code or for an adjudication of insolvency, or
shall consent to the institution of bankruptcy or insolvency proceedings
against it, or shall file a petition seeking, or seek or consent to
reorganization, arrangement, composition or relief under the Bankruptcy Code or
any applicable State law, or shall consent to the filing of such petition or to
the appointment of a receiver, custodian, liquidator, assignee, trustee,
sequestrator or similar official of the Company or of substantially all of its
property, or the Company shall make a general assignment for the benefit of
creditors as recognized under the Bankruptcy Code, then all Senior Indebtedness
(including any interest thereon accruing after the commencement of any such
proceedings) shall first be paid in full before any payment or distribution,
whether in cash, securities or other property, shall be made to any Holder of
any Securities on account thereof. Any payment or distribution, whether in
cash, securities or other property (other than securities of the Company or any
other corporation provided for by a plan of reorganization or readjustment the
payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the indebtedness evidenced by the
Securities, to the payment of all Senior Indebtedness then outstanding and to
any securities issued in respect thereof under any such plan of reorganization
or readjustment), which would otherwise (but for these subordination
provisions) be payable or deliverable in respect of the Securities of any
series shall be paid or delivered directly to the holders of Senior
Indebtedness in accordance with the priorities then existing among such holders
until all Senior Indebtedness (including any interest thereon accruing after
the commencement of any such proceedings) shall have been paid in full. In the
event of any such proceeding, after payment in full of all sums owing with
respect to Senior Indebtedness, the Holders of the Securities, together with
the holders of any other obligations of the Company ranking on a parity with
the Securities, shall be entitled to be paid from the remaining assets of the
Company the amounts at the time due and owing on account of unpaid principal of
and any premium and interest on the Securities and such other obligations
before any payment or other distribution, whether in cash, property or
otherwise, shall be made on account of any capital stock or any obligations of
the Company ranking junior to the Securities and such other obligations.





                                       76
<PAGE>   84
     If, notwithstanding the foregoing, any payment or distribution of any
character, whether in cash, securities or other property (other than securities
of the Company or any other corporation provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in these subordination provisions with respect to the
indebtedness evidenced by the Securities, to the payment of all Senior
Indebtedness then outstanding and to any securities issued in respect thereof
under any such plan of reorganization or readjustment), shall be received by
the Trustee or any Holder in contravention of any of the terms hereof, such
payment or distribution shall be received in trust for the benefit of, and
shall be paid over or delivered and transferred to, the holders of the Senior
Indebtedness then outstanding in accordance with the priorities then existing
among such holders for application to the payment of all Senior Indebtedness
remaining unpaid, to the extent necessary to pay all such Senior Indebtedness
in full. In the event of the failure of the Trustee or any Holder to endorse or
assign any such payment, distribution or security, each holder of Senior
Indebtedness is hereby irrevocably authorized to endorse or assign the same.

     No present or future holder of any Senior Indebtedness shall be prejudiced
in the right to enforce subordination of the indebtedness evidenced by the
Securities by any act or failure to act on the part of the Company. Nothing
contained herein shall impair, as between the Company and the Holders of
Securities of each series, the obligation of the Company to pay to such Holders
the principal of and any premium and interest on such Securities or prevent the
Trustee or the Holder from exercising all rights, powers and remedies otherwise
permitted by applicable law or hereunder upon a default or Event of Default
hereunder, all subject to the rights of the holders of the Senior Indebtedness
to receive cash, securities or other property otherwise payable or deliverable
to the Holders.

     Senior Indebtedness shall not be deemed to have been paid in full unless
the holders thereof shall have received cash, securities or other property
equal to the amount of such Senior Indebtedness then outstanding. Upon the
payment in full of all Senior Indebtedness, the Holders of Securities of each
series shall be subrogated to all rights of any holders of Senior Indebtedness
to receive any further payments or distributions applicable to the Senior
Indebtedness until the indebtedness evidenced by the Securities of such series
shall have been paid in full, and such payments or distributions received by
such Holders, by reason of such subrogation, of cash, securities or other
property which otherwise would be paid or distributed to the holders of Senior
Indebtedness, shall, as between the Company and its creditors other than the
holders of Senior Indebtedness, on the one hand, and such Holders, on the other
hand, be deemed to be a payment by the Company on account of Senior
Indebtedness, and not on account of the Securities of such series.

     The provisions of this Section 1601 shall not impair any rights,
interests, remedies or powers of any secured creditor of the Company in respect
of any security interest the creation of which is not prohibited by the
provisions of this Indenture.

     The securing of any obligations of the Company, otherwise ranking on a
parity with the Securities of ranking junior to the Securities, shall not be
deemed to prevent such obligations from





                                       77
<PAGE>   85
constituting, respectively, obligations ranking on a parity with the Securities
or ranking junior to the Securities.

SECTION 1602.  Reliance on Certificate of Liquidating Agent; Further
               Evidence as to Ownership of Senior Indebtedness.

     Upon any payment or distribution of assets of the Company, the Trustee and
the Holders shall be entitled to rely upon an order or decree issued by any
court of competent jurisdiction in which such dissolution or winding-up or
liquidation or reorganization or arrangement proceedings are pending or upon a
certificate of the trustee in bankruptcy, receiver, assignee for the benefit of
creditors or other Person making such payment or distribution, delivered to the
Trustee or to the Holders, for the purpose of ascertaining the Persons entitled
to participate in such distribution, the holders of the Senior Indebtedness and
other indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Sixteen. In the absence of any such bankruptcy
trustee, receiver, assignee or other Person, the Trustee shall be entitled to
rely upon 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)
as evidence that such Person is a holder of Senior Indebtedness (or is such a
trustee or representative). If 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 Sixteen, 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, as to the extent to which such
Person is entitled to participate in such payment or distribution, and as to
other facts pertinent to the rights of such Person under this Article Sixteen,
and if such evidence is not furnished, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment.

SECTION 1603.  Payment Permitted If No Default.

     Nothing contained in this Article Sixteen shall prevent (a) the Company at
any time, except during the pendency of any default in the payment of any
principal of or premium or interest on any Senior Indebtedness as described in
Section 1601  or of any of the events described in clauses (a) and (b) of
Section 1601, from making payments of the principal of or any premium or
interest on the Securities, or (b) the application by the Trustee or any Paying
Agent of any moneys deposited with it hereunder to payments of the principal of
or any premium or interest, on the Securities, unless and until the Trustee or
such Paying Agent, as the case may be, shall have timely received the Officers'
Certificate or written notice provided for in Section 1605.

SECTION 1604.  Disputes with Holders of Certain Senior Indebtedness.

     Any failure by the Company to make any payment on or under any Senior
Indebtedness, other than any Senior Indebtedness as to which the provisions of
this Section 1604 shall have been waived by the Company in the instrument or
instruments by which the Company incurred, assumed, guaranteed or otherwise
created such Senior Indebtedness, shall not be deemed a default under





                                       78
<PAGE>   86
Section 1601 if (i) the Company 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 Company 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, or (B) in the event of a
judgment that is subject to further review or appeal has been issued, the
Company 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 1605.  Trustee Not Charged with Knowledge of Prohibition.

     Anything in this Article Sixteen or elsewhere in this Indenture contained
to the contrary notwithstanding, the Trustee shall not at any time be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment of moneys to or by Trustee and shall be entitled to assume
conclusively that no such facts exist and that no event specified in clauses
(a) and (b) of Section 1601 has happened, unless and until the Trustee shall
have received an Officers' Certificate to that effect or notice in writing to
that effect signed by or on behalf of the holder or holders, or their
representatives, of Senior Indebtedness who shall have been certified by the
Company or otherwise established to the reasonable satisfaction of the Trustee
to be such holder or holders or representatives or from any trustee under any
indenture pursuant to which such Senior Indebtedness shall be outstanding;
provided, however, that, if the Trustee shall not have received the Officers'
Certificate or notice provided for in this Section 1605 at least three Business
Days preceding 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 of or any premium or interest on any Security), then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such moneys and apply the same to the purpose
for which they were received and shall not be affected by any notice to the
contrary which may be received by it within three Business Days preceding such
date. The Company shall give prompt written notice to the Trustee and to each
Paying Agent of any facts which would prohibit any payment of moneys to or by
the Trustee or any Paying Agent, and the Trustee shall not be charged with
knowledge of the curing of any default or the elimination of any other fact or
condition preventing such payment or distribution unless and until the Trustee
shall have received an Officers' Certificate to such effect.

SECTION 1606.  Trustee to Effectuate Subordination.

     Each Holder of Securities by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination as between such Holder and holders
of Senior Indebtedness as provided in this Article Sixteen and appoints the
Trustee its attorney-in-fact for any and all such purposes.

SECTION 1607.  Rights of Trustee as Holder of Senior Indebtedness.

     The Trustee shall be entitled to all the rights set forth in this Article
Sixteen with respect to any Senior Indebtedness which may at the time be 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. Nothing in this Article Sixteen shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 607.

SECTION 1608.  Article Applicable to Paying Agents.

     In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article Sixteen 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 the Paying Agent
were named in this Article Sixteen in addition to or in place of the Trustee;
provided, however, that Sections 1605 and 1607 shall not apply to the Company
if its acts as Paying Agent.

SECTION 1609.  Subordination Rights Not Impaired by Acts or Omissions of
               the Company or Holders of Senior Indebtedness.

     No right of any present or future holders of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof which any such holder may have
or be otherwise charged with.  The holders of Senior Indebtedness may, at any
time or from time to time and in their absolute discretion, change the manner,
place or terms of payment, change or extend the time of payment of, or renew or
alter, any such Senior Indebtedness, or amend or supplement any instrument
pursuant to which any such Senior Indebtedness is issued or by which it may be
secured, or release any security therefor, or exercise or refrain from
exercising any other of their rights under the Senior Indebtedness, including,
without limitation, the waiver of default thereunder, all without notice to or
assent from the Holders of the Securities or the Trustee and without affecting
the obligations of the Company, the Trustee or the Holders of Securities under
this Article Sixteen.

SECTION 1610.  Trustee Not Fiduciary for Holders of Senior Indebtedness.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders
of the Senior Indebtedness, and shall not be liable to any such holders if it
shall mistakenly pay over or distribute money or assets to Securityholders or
the Company.   

                          ----------------------------

     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.

                               (the "Securities")

     This is to certify that as of the date hereof, and except as set forth
below, the above-captioned Securities held by you for our account (i) are owned
by person(s) that are not citizens or residents of the United States, domestic
partnerships, domestic corporations or any estate or trust the income of which
is subject to United States Federal income taxation regardless of its source
("United States persons"), (ii) are owned by United States person(s) that are

who acquired Securities through the foreign branches of the United States
financial institutions and who hold the Securities through such United States

through its agent, to comply with the requirements of Section 165(j)(3)(A), (B)
or (C) of the Internal Revenue Code of 1986 as amended, and the regulations
thereunder), or (iii) are owned by United States or foreign financial

clause (i) or (ii)), this is to further certify that such financial institution
has not acquired the Securities for purposes of resale directly or indirectly
to a United States person or to a person within the United States or its
possessions.

     If the Securities are of the category contemplated in Section
230.903(c)(3) of Regulation S under the Securities Act of 1933, as amended (the
"Act"), then this is also to certify that, except as set forth below (i) in the
case of debt securities, the Securities are beneficially owned by (a) non-U.S.
person(s) or (b) U.S. person(s) who purchased the Securities in transactions
which did not require registration under the Act; or (ii) in the case of equity
securities, the Securities are owned by (x) non-U.S. person(s) (and such
person(s) are not acquiring the Securities for the account or benefit of U.S.
person(s)), or (y) U.S. person(s) who purchased the Securities in a transaction
which did not require registration under the Act.  If this certification is
being delivered in connection with the exercise of warrants pursuant to Section
230.902(m) of Regulation S under the Act, then this is further to certify that,
except as set forth below, the Securities are being exercised by and on behalf
of non-U.S. person(s).  As used in this paragraph, the term "U.S. person" has
the meaning given to it by Regulation S under the Act.
