ITEM  1.    BUSINESS.

                                    GENERAL

              The registrant, Union Electric Company (the "Company"),
incorporated in Missouri in 1922, is successor to a number of companies, the
oldest of which was organized in 1881.  The Company, which is the largest
electric utility in the State of Missouri, supplies electric service in
territories in Missouri and Illinois having an estimated population of
2,600,000 within an area of approximately 24,500 square miles, including the
greater St. Louis area.  Retail gas service is supplied in 90 Missouri
communities and in the City of Alton, Illinois and vicinity.

              On August 11, 1995, the Company and CIPSCO Incorporated
("CIPSCO") entered into an Agreement and Plan of Merger, which was subsequently
approved by the shareholders of both companies.  The merger ("Merger") is
further conditioned on, among other things, receipt of certain regulatory and
governmental approvals and is expected to be consummated by the end of 1997.
Upon completion of the Merger, two operating companies will continue as
subsidiaries of a newly formed holding company, Ameren Corporation.

              On February 21, 1997, the Missouri Public Service Commission
("MoPSC") entered a final order approving the Merger.  In the order the MoPSC
also approved a joint agreement dated July 12, 1996 between the Company, the
MoPSC staff, the Office of the Public Counsel and others.  This agreement is
described in Note 3 under "Notes to Financial Statements" on Pages 30 and 31 of
the 1996 Annual Report pages incorporated herein by reference.  In addition,
the order requires the Company to take steps to participate in or form an
Independent System Operator to control the operation, pricing and planning of
the Company's transmission system, as well as file a report with the MoPSC that
assesses the potential ability of the merged companies to exercise vertical and
horizontal market power in price deregulated retail generation.  That report is
due by January 1, 1998.  The MoPSC's order became effective on March 4, 1997.

              On March 3, 1997, the Illinois Commerce Commission ("ICC")
expanded the scope of issues it will consider in connection with the Merger
proceedings.  In addition to market power issues, the ICC ordered that issues
related to the treatment of affiliate transactions, as well as ICC
jurisdictional issues, be addressed as part of the Merger proceedings.

              Hearings at the Federal Energy Regulatory Commission on the
Merger have concluded and the administrative law judge's proposed order is
expected by April 30, 1997.

              For additional information on the Merger, see Notes 2 and 3 to
the "Notes to Financial Statements" on Pages 29 and 30 of the 1996 Annual
Report pages incorporated herein by reference.  Also, see Item 14 below for
unaudited pro forma financial information for Ameren Corporation.

              For the year 1996, 95.6% of total operating revenues was derived
from the sale of electric energy and 4.4% from the sale of natural gas.
Electric operating revenues as a percentage of total operating revenues for the
years 1992, 1993, 1994, and 1995 were 95.9%, 95.5%, 96.1%, and 96.1%,
respectively.

              The Company employed 6,035 persons at December 31, 1996.
Approximately 70% of the Company's employees are represented by local unions
affiliated with the AFL-CIO.  Labor agreements covering 4,132 employees expired
in 1996.  New agreements covering 1,061 employees





                                     - 1 -
<PAGE>   4

have been negotiated and expire in 1999.  Agreements covering 3,188 employes
continue to be negotiated.  Two agreements covering 117 employees will expire
in 1997.


                       CONSTRUCTION PROGRAM AND FINANCING

              The Company is engaged in a construction program under which
expenditures averaging approximately $267 million are anticipated during each
of the next five years.  Capital expenditures for compliance with the Clean Air
Act Amendments of 1990 are included in the construction program -- also see
"Regulation", below.  The Company does not anticipate a need for additional
base load electric generating capacity until after the year 2013.

              During the five-year period ended 1996, gross additions to the
property of the Company, including allowance for funds used during construction
and excluding nuclear fuel, were approximately $1.5 billion (including $325
million in 1996) and property retirements were $265 million.

              In addition to the funds required for construction during the
1997-2001 period, $174 million will be required to repay long-term debt as
follows:  $74 million in 1997 and $100 million in 1999.  Amounts for years
subsequent to 1997 do not include nuclear fuel lease payments since the amounts
of such payments are not currently determinable.

              For information on the Company's external cash sources, see
"Liquidity and Capital Resources" under "Management's Discussion and Analysis"
on Page 19 of the 1996 Annual Report pages incorporated herein by reference.

              FINANCING RESTRICTIONS.  Under the most restrictive earnings test
contained in the Company's principal Indenture of Mortgage and Deed of Trust
("Mortgage") relating to its First Mortgage Bonds ("Bonds"), no Bonds may be
issued (except in certain refunding operations) unless the Company's net
earnings available for interest after depreciation for 12 consecutive months
within the 15 months preceding such issuance are at least two times annual
interest charges on all Bonds and prior lien bonds then outstanding and to be
issued (all calculated as provided in the Mortgage).  Such ratio for the 12
months ended December 31, 1996 was 6.4, which would permit the Company to issue
an additional $2.7 billion of Bonds (8% annual interest rate assumed).
Additionally, the Mortgage permits issuance of new bonds up to (a) 60% of
defined property additions, or (b) the amount of previous bonds retired or to
be retired, or (c) the amount of cash put up for such purpose.  At December 31,
1996, the aggregate amount of Bonds issuable under (a) and (b) above was
approximately $2 billion.

              The Company's Restated Articles of Incorporation restrict the
Company from selling Preferred Stock unless its net earnings for a period of 12
consecutive months within 15 months preceding such sale are at least two and
one-half times the annual dividend requirements on its Preferred Stock then
outstanding and to be issued.  Such ratio for the 12 months ended December 31,
1996 was 22.7, which would permit the Company to issue an additional $1.3
billion stated value of Preferred Stock (8% annual dividend rate assumed).
Certain other financing arrangements require the Company to obtain prior
consents to various actions by the Company, including any future borrowings,
except for permitted financings such as borrowings under revolving credit
agreements, the nuclear fuel lease, unsecured short-term borrowings (subject to
certain conditions), and the issuance of additional Bonds.

                                     RATES

              For the year 1996, approximately 83%, 7%, and 10% of the
Company's electric operating revenues were based on rates regulated by the
MoPSC, the ICC, and the Federal Energy Regulatory Commission ("FERC") of the U.
S. Department of Energy, respectively.

              For additional information on "Rates", see Note 3 to the "Notes
to Financial Statements" on Page 30 of the 1996 Annual Report pages
incorporated herein by reference.

</TABLE>

           COAL.  Because of uncertainties of supply due to potential work
stoppages, equipment breakdowns and other factors, the Company has a policy of
maintaining a coal inventory of 75 days, based on normal annual burn practices.
See "Regulation" for additional reference to the Company's coal requirements.

           NUCLEAR.  The components of the nuclear fuel cycle required for
nuclear generating units are as follows:  (1) uranium; (2) conversion of
uranium into uranium hexafluoride; (3) enrichment of uranium hexafluoride; (4)
conversion of enriched uranium hexafluoride into uranium dioxide and the
fabrication into nuclear fuel assemblies; and (5) disposal and/or reprocessing
of spent nuclear fuel.

           The Company has agreements to fulfill its needs for uranium,
enrichment, and fabrication services through 2002.  The Company's agreements
for conversion services are sufficient to supply the Callaway Plant through
1999.  Additional contracts will have to be entered into in order to supply
nuclear fuel during the remainder of the life of the Plant, at prices which
cannot now be accurately predicted.  The Callaway Plant normally requires
re-fueling at 18-month intervals and re-fuelings are presently scheduled for
the spring of 1998 and the fall of 1999.

           Under the Nuclear Waste Policy Act of 1982, the U. S. Department of
Energy ("DOE") is responsible for the permanent storage and disposal of spent
nuclear fuel.  DOE currently charges one mill per nuclear generated
kilowatt-hour sold for future disposal of spent fuel.  Electric rates charged
to customers provide for recovery of such costs.  DOE is not expected to have
its permanent storage facility for spent fuel available until at least 2015.
The Company has sufficient storage capacity at the Callaway Plant site until
2005 and has viable storage alternatives under consideration.  Each alternative
will likely require Nuclear Regulatory Commission approval and may require
other regulatory approvals. The delayed availability of DOE's disposal facility
is not expected to adversely affect the continued operation of the Callaway
Plant.

           OIL AND GAS.  The actual and prospective use of such fuels is
minimal, and the Company has not experienced and does not expect to experience
difficulty in obtaining adequate supplies.

           For additional information on the Company's "Fuel Supply", see Note
11 to the "Notes to Financial Statements" on Page 34 of the 1996 Annual Report
pages incorporated herein by reference.

                                   REGULATION

           The Company is subject to regulation by the MoPSC and the ICC as to
rates, service, accounts, issuance of equity securities, issuance of debt
having a maturity of more than twelve months, mergers, and various other
matters.  The Company is also subject to regulation by the FERC as to rates and
charges in connection with the transmission of electric energy in interstate
commerce and the sale of such energy at wholesale in interstate commerce,
mergers, and certain other matters.  Authorization to issue debt having a
maturity of twelve months or less is obtained from the FERC.

           Operation of the Company's Callaway Plant is subject to regulation
by the Nuclear Regulatory Commission.  The Company's Facility Operating License
for the Callaway Plant expires on October 18, 2024.

           The Company's Osage hydroelectric plant and its Taum Sauk
pumped-storage hydro plant, as licensed projects under the Federal Power Act,
are subject to certain federal regulations affecting, among other things, the
general operation and maintenance of the projects.  The Company's license for
the Osage Plant expires on February 28, 2006, and its license for the Taum Sauk
Plant expires on June 30, 2010.  The Company's Keokuk Plant and dam located in
the Mississippi River between Hamilton, Illinois and Keokuk, Iowa, are operated
under authority, unlimited in time, granted by an Act of Congress in 1905.

           The Company is exempt from the provisions of the Public Utility
Holding Company Act of 1935 ("PUHCA"), except Section 9(a)(2) relating to the
acquisition of securities of other public utility companies and Section
11(b)(2) with respect to concluding matters relating to the 1974 acquisition of
the common stock of a former subsidiary.  When the Securities and Exchange
Commission approved such acquisition it reserved jurisdiction to pass upon the
right of the Company to retain its gas properties.  For information on PUHCA
and the Merger, see Note 2 to the "Notes to Financial Statements" on Page 30 of
the 1996 Annual Report pages incorporated herein by reference.

           The Company is regulated, in certain of its operations, by air and
water pollution and hazardous waste regulations at the city, county, state and
federal levels.  The Company is in substantial compliance with such existing
regulations.

           Under the Clean Air Act Amendments of 1990, the Company is required
to reduce total annual emissions of sulfur dioxide by the year 2000.
Significant reductions in nitrogen oxide will also be required.  By switching
to low-sulfur coal and early banking of emission credits, the Company
anticipates that it can comply with the requirements of the law with no
significant revenue increases because the related capital costs, estimated at
about $300 million, are largely offset by lower fuel costs.  As of the end of
1996 about 84% of the Clean Air Act related capital costs had been expended.

           As of December 31, 1996, the Company was designated a potentially
responsible party ("PRP") by federal and state environmental protection
agencies at four hazardous waste sites.  Other hazardous waste sites have been
identified for which the Company may be responsible but has not been designated
a PRP.  The Company continually reviews the remediation costs that will be

required for all of these sites.  However, such costs are not expected to have
a material adverse effect on the Company's financial position, results of
operations or liquidity.

           Other aspects of the Company's business are subject to the
jurisdiction of various regulatory authorities and, for additional information
on regulations, see Note 3 to the "Notes to Financial Statements" on Page 30 of
the 1996 Annual Report pages incorporated herein by reference.

                                INDUSTRY ISSUES

           The Company is facing issues common to the electric and gas utility
industries which have emerged during the past several years.  These issues
include:  the potential for more intense competition and for changing the
structure of regulation; changes in the structure of the industry as a result
of amendments to federal laws regulating ownership of generating facilities and
access to transmission systems; on-going consideration of additional changes of
the industry by federal and state authorities; continually developing
environmental laws, regulations and issues including proposed new air quality
standards; public concern about the siting of new facilities; proposals for
demand side management programs; and public concerns about nuclear
decommissioning and the disposal of nuclear wastes, and about global climate
issues.  The Company is monitoring these issues and is unable to predict at
this time what impact, if any, these issues will have on its operations,
financial condition, or liquidity.

</TABLE>

           In planning its construction program, the Company is presently
utilizing a forecast of kilowatthour sales growth of approximately 1.9% and
peak load growth of 1%, each compounded annually, and is providing for a
minimum reserve margin of approximately 17% to 21% above its anticipated peak
load requirements.

           See "Operating Statistics", incorporated by reference in Part I of
this Form 10-K, for information on loads and capability during the five-year
period ended 1996.

           The Company is a member of one of the ten regional electric
reliability councils organized for coordinating the planning and operation of
the nation's bulk power supply - MAIN (Mid-America Interconnected Network)
operating primarily in Wisconsin, Illinois and Missouri.  The Company has
interconnections for the exchange of power, directly and through the facilities
of others, with thirteen private utilities and with Associated Electric
Cooperative, Inc., the City of Columbia, Missouri, the Southwestern Power
Administration and the Tennessee Valley Authority.

           The Company owns 40% of the capital stock of Electric Energy, Inc.
("EEI"), the balance of which is held by three other sponsoring companies --
Kentucky Utilities Company ("KU"), Central Illinois Public Service Company
("CIPS" -- a subsidiary of CIPSCO), and Illinova Generating ("IG").  EEI owns
and operates a generating plant with a nominal capacity of 1,000





                                     - 7 -
<PAGE>   10

mW.  60% of the plant's output is committed to the Paducah Project of the DOE,
20% is committed to KU, 10% to the Company, and 5% each to IG and CIPS.

           As of December 31, 1996, the Company owned approximately 3,300
circuit miles of electric transmission lines and substations with a transformer
capacity of approximately 45,497,000 kVA.  The Company operates three
propane-air plants with an aggregate daily natural gas equivalent
deliverability of 23 million Btu and 2,688 miles of gas mains.  Other
properties of the Company include distribution lines, underground cable, steam
distribution facilities in Jefferson City, Missouri and office buildings,
warehouses, garages and repair shops.

           The Company has fee title to all principal plants and other
important units of property, or to the real property on which such facilities
are located (subject to mortgage liens securing outstanding indebtedness of the
Company and to permitted liens and judgment liens, as defined), except that (i)
a portion of the Osage Plant reservoir, certain facilities at the Sioux Plant,
certain of the Company's substations and most of its transmission and
distribution lines and gas mains are situated on lands occupied under leases,
easements, franchises, licenses or permits; (ii) the United States and/or the
State of Missouri own, or have or may have, paramount rights to certain lands
lying in the bed of the Osage River or located between the inner and outer
harbor lines of the Mississippi River, on which certain generating and other
properties of the Company are located; and (iii) the United States and/or State
of Illinois and/or State of Iowa and/or City of Keokuk, Iowa own, or have or
may have, paramount rights with respect to, certain lands lying in the bed of
the Mississippi River on which a portion of the Company's Keokuk Plant is
located.

           Substantially all of the Company's property and plant is subject to
the direct first lien of an Indenture of Mortgage and Deed of Trust dated June
15, 1937, as amended and supplemented.  As part of the 1983 merger of the
Company with its utility subsidiaries, the Company assumed the mortgage
indenture of each subsidiary.  Currently, the prior liens of two former
subsidiary indentures extend to the property and franchises acquired by the
Company from such subsidiaries.  Such indentures also contain provisions
subjecting to the prior lien thereof after-acquired property of the Company
constituting (with certain exceptions) additions, extensions, improvements,
repairs, and replacements appurtenant to property acquired in the merger.  In
addition, one such indenture contains a provision subjecting to the prior lien
thereof after-acquired property of the Company situated in the territory served
by the former subsidiary prior to the merger.  Further, no debt is outstanding
under the one such indenture, and the Company is in the process of
extinguishing the lien of such indenture.

ITEM    3.   LEGAL PROCEEDINGS.

         The Company is involved in legal and administrative proceedings before
various courts and agencies with respect to matters arising in the ordinary
course of business, some of which involve substantial amounts.  Management is
of the opinion that the final disposition of these proceedings will not have a
material adverse effect on the Company's financial position, results of
operations, or liquidity.

                        _______________________________

                        ON FINANCIAL STATEMENT SCHEDULE



To the Board of Directors
of Union Electric Company

Our audits of the financial statements referred to in our report dated February
4, 1997 appearing on page 16 of the 1996 Annual Report to Stockholders of Union
Electric Company (which report and financial statements are incorporated by
reference in this Annual Report on Form 10-K) also included an audit of the
Financial Statement Schedule listed in Item 14(a) of this Form 10-K.  In our
opinion, this Financial Statement Schedule presents fairly, in all material
respects, the information set forth therein when read in conjunction with the
related financial statements.

UNAUDITED PRO FORMA FINANCIAL INFORMATION

AMEREN CORPORATION

           The following unaudited pro forma financial information combines the
historical balance sheets and statements of income of the Company and CIPSCO
Incorporated, including their respective subsidiaries, after giving effect to
the Merger.  The unaudited pro forma combined condensed balance sheet at
December 31, 1996 gives effect to the Merger as if it had occurred at December
31, 1996.  The unaudited pro forma combined condensed statements of income for
each of the years ended December 31, 1996, 1995, and 1994, give effect to the
Merger as if it had occurred at the beginning of the periods presented.  These
statements are prepared on the basis of accounting for the Merger as a pooling
of interests and are based on the assumptions set forth in the notes thereto.
In addition, the pro forma financial information does not give effect to the
expected synergies of the transaction.

           The following pro forma financial information has been prepared
from, and should be read in conjunction with, the historical financial
statements and related notes thereto of the Company and CIPSCO.  The following
information is not necessarily indicative of the financial position or
operating results that would have occurred had the Merger been consummated on
the date, or at the beginning of the periods, for which the Merger is being
given effect nor is it necessarily indicative of future operating results or
financial position.

                               AMEREN CORPORATION


NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

1.  Reclassifications were made to certain "as reported" account balances
    reflected in the registrant's and CIPSCO's financial statements to conform
    to this reporting presentation (See Notes 6, 7 and 8).  All other financial
    statement presentation and accounting policy differences were immaterial
    and were not adjusted in the pro forma combined condensed financial
    statements.

2.  The pro forma combined condensed financial statements reflect the
    conversion of each share of the registrant's Common Stock ($5 par value)
    outstanding into one share of Ameren Common Stock ($.01 par value) and the
    conversion of each share of CIPSCO Common Stock (no par value) outstanding
    into 1.03 shares of Ameren Common Stock, as provided in the Merger
    Agreement.  The pro forma combined condensed financial statements are
    presented as if the companies were combined during all periods included
    therein.

3.  Net income for the twelve months ended December 31, 1995 included CIPSCO's
    pre-tax charge of $5.8 million for a voluntary separation program and $5.7
    million of system development expenses.

4.  The allocation between the registrant and CIPSCO and their customers of the
    estimated cost savings, resulting from the merger, net of the costs
    incurred to achieve such savings, will be subject to regulatory review and
    approval.  Merger-related costs (which include transaction costs and costs
    to achieve such savings) are currently estimated to be approximately $73
    million (including costs for financial advisors, attorneys, accountants,
    consultants, filings, printing, system integration, relocation, etc.).
    None of these estimated cost savings have been reflected in the pro forma
    combined condensed financial statements.  However, net income for the
    twelve months ended December 31, 1996 and 1995, included merger-related
    costs of $7.9 million and $9.0 million, net of income taxes, for the
    registrant, and $4.9 million and $4.7 million, net of income taxes, for
    CIPSCO, respectively.

5.  Intercompany transactions (including purchased and exchanged power
    transactions) between the registrant and CIPSCO during the periods
    presented were not material and, accordingly, no pro forma adjustments were
    made to eliminate such transactions.

6.  CIPSCO's regulatory asset related to deferred income taxes was reclassified
    from the regulatory liability account balance to conform to this reporting
    presentation.

7.  CIPSCO's income taxes are reflected as operating expenses to conform to
    this reporting presentation.

8.  Currently, the registrant's Preferred Stock is not issued by a subsidiary;
    subsequent to the merger, the registrant's Preferred Stock will be issued
    by a subsidiary of Ameren.  As a result, the registrant's preferred
    dividend requirements have been reclassified to conform to this reporting
    presentation.

9.  Pro forma adjustments have been made to consolidate the financial results
    of Electric Energy, Inc. (EEI), which will, in substance, be a 60% owned
    subsidiary of Ameren subsequent to the merger.  Prior to the merger, the
    registrant and CIPSCO held 40% and 20% ownership interests, respectively,
    in EEI and accounted for these investments under the equity method of
    accounting.  All intercompany transactions between the registrant, CIPSCO
    and EEI were eliminated.

10.  Net income for the twelve months ended December 31, 1996 and 1995 included
    credits for Missouri electric customers which reduced revenues and pre-tax
    income of the registrant by $47 million and $30 million, respectively.

                   for such purposes shall be the amount of Dollars which could

                   of a Discount Security, the Dollar equivalent on the date

                   from such three banks, on such other quotations or
                   alternative methods of determination which shall be as
                   consistent as practicable with the method set forth in (i)
                   above;

which the furnishing of such documents is specifically required by any

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

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

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


SECTION 104. ACTS OF HOLDERS.

                   (a) Any request, demand, authorization, direction, notice,
             consent, election, waiver or other action provided by this
             Indenture to be made, given or taken by Holders may be embodied in
             and evidenced by one or more instruments of substantially similar
             tenor signed





                                      -8-


<PAGE>   19


             by such Holders in person or by an agent duly appointed in writing
             or, alternatively, may be embodied in and evidenced by the record
             of Holders voting in favor thereof, either in person or by proxies
             duly appointed in writing, at any meeting of Holders duly called
             and held in accordance with the provisions of Article Thirteen, 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 of the holding by any
             Person of a Security, shall be sufficient for any purpose of this
             Indenture and (subject to Section 901) 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 shall be proved in
             the manner provided in Section 1306.

                   (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 or may be proved
             in any other manner which the Trustee and the Company deem
             sufficient.  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.

                   (c) The principal amount (except as otherwise contemplated
             in clause (y) of the proviso to the definition of Outstanding) and
             serial numbers of Securities held by any Person, and the date of
             holding the same, shall be proved by the Security Register.

                   (d) Any request, demand, authorization, direction, notice,
             consent, election, waiver or other Act of a Holder 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.

                   (e) Until such time as written instruments shall have been
             delivered to the Trustee with respect to the requisite percentage
             of principal amount of Securities for the action contemplated by
             such instruments, any such instrument executed and delivered by or
             on behalf of a Holder may be revoked with respect to any or all of
             such Securities by written notice by such Holder or any subsequent
             Holder, proven in the manner in which such instrument was proven.

                   (f) Securities of any series, or any Tranche thereof,
             authenticated and delivered after any Act of Holders may, and
             shall if required by the Trustee, bear a notation in form approved
             by the Trustee as to any action taken by such Act of Holders.  If
             the Company shall so determine, new Securities of any series, or
             any Tranche thereof, so modified as to conform, in the opinion of
             the Trustee and the Company, to such action may be prepared and
             executed by the Company and authenticated and delivered by the
             Trustee in exchange for Outstanding Securities of such series or
             Tranche.

<PAGE>   20


                   (g) If the Company shall solicit from Holders any request,
             demand, authorization, direction, notice, consent, waiver or other
             Act, the Company may, at its option, by Board Resolution, fix in
             advance a record date for the determination of Holders entitled to
             give such request, demand, authorization, direction, notice,
             consent, waiver or other Act, but the Company shall have no
             obligation to do so.  If such a record date is fixed, such
             request, demand, authorization, direction, notice, consent, waiver
             or other Act may be given before or after such record date, but
             only the Holders of record at the close of business on the record
             date shall be deemed to be Holders for the purposes of determining
             whether Holders of the requisite proportion of the Outstanding
             Securities have authorized or agreed or consented to such request,
             demand, authorization, direction, notice, consent, waiver or other
             Act, and for that purpose the Outstanding Securities shall be
             computed as of the record date.

SECTION 106. NOTICE TO HOLDERS OF SECURITIES; WAIVER.

             Except as otherwise expressly provided herein, where this
Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given, and shall be deemed given, to Holders if in writing and
mailed, first-class postage prepaid, to each Holder 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.

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

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

SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

             If any provision of this Indenture limits, qualifies or conflicts
with another provision hereof which is required or deemed to be included in
this Indenture by, or is otherwise governed by, any of the provisions of the
Trust Indenture Act, such other provision shall control; and if any provision
hereof otherwise conflicts with the Trust Indenture Act, the Trust Indenture
Act shall control.

SECTION 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

SECTION 109. SUCCESSORS AND ASSIGNS.

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

SECTION 110. SEPARABILITY CLAUSE.

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

SECTION 111. BENEFITS OF INDENTURE.

             Nothing in this Indenture or the Securities, express or implied,
shall give to any Person, other than the parties hereto, their successors
hereunder, the Holders, and so long as the notice described

             This Indenture and the Securities shall be governed by and
construed in accordance with the laws of the State of New York, except to the
extent that the law of any other jurisdiction shall be mandatorily applicable.

SECTION 113. 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 other than a provision in Securities of any series, or any Tranche
thereof, or in the Board Resolution or Officer's Certificate which establishes
the terms of the Securities of such series or Tranche, 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, except that if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day in each case with the same force and effect as if made
on the Interest Payment Date or Redemption Date, or at the Stated Maturity,
and, if such payment is made or duly provided for on such Business Day, 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, to such Business Day.

                         or affecting generally the enforcement of creditors'
                         rights, including, without limitation, bankruptcy and
                         insolvency laws and to general principles of equity
                         (regardless of whether such enforceability is
                         considered in a proceeding in equity or at law);

provided, however, that, with respect to Securities of a series subject to a
Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel only once at or prior to the time of the first authentication of such
Securities (provided that such Opinion of Counsel addresses the authentication
and delivery of all Securities of such series) and that in lieu of the opinions
described in clauses (ii) and (iii) above Counsel may opine that:

                         (x) when the terms of such Securities shall have been
                   established pursuant to a Company Order or Orders or
                   pursuant to such procedures (acceptable to the Trustee) as
                   may be specified from time to time by a Company Order or
                   Orders, all as contemplated by and in accordance with the
                   instrument or instruments delivered pursuant to clause (a)
                   above, such terms will have been duly authorized by the
                   Company and will have been established in conformity with
                   the provisions of this Indenture; and

                         (y) such Securities, when authenticated and delivered
                   by the Trustee in accordance with this Indenture and the
                   Company Order or Orders or specified procedures referred to
                   in paragraph (x) above and issued and delivered by the
                   Company in the manner and subject to any conditions
                   specified in such Opinion of Counsel, will have been duly
                   issued under this Indenture and will constitute valid and
                   legally binding obligations of the Company, entitled to the
                   benefits provided by the Indenture, and enforceable in
                   accordance with their terms, subject, as to enforcement, to
                   laws relating to or affecting generally the enforcement of
                   creditors' rights, including, without limitation, bankruptcy
                   and insolvency laws and to general principles of equity
                   (regardless of whether such enforceability is considered in
                   a proceeding in equity or at law).

             With respect to Securities of a series subject to a Periodic
Offering, the Trustee may conclusively rely, as to the authorization by the
Company of any of such Securities, the form and terms thereof and the legality,
validity, binding effect and enforceability thereof, upon the Opinion of
Counsel and other documents delivered pursuant to Sections 201 and 301 and this
Section, as applicable, at or prior to the time of the first authentication of
Securities of such series unless and until such opinion or other documents have
been superseded or revoked or expire by their terms.  In connection with the
authentication and delivery of Securities of a series subject to a Periodic
Offering, the Trustee shall be entitled to conclusively rely that the Company's
instructions to authenticate and deliver such Securities do not violate any
rules, regulations or orders of any Governmental Authority having jurisdiction
over the Company.

             If the form or terms of the Securities of any series have been
established by or pursuant to a Board Resolution or an Officer's Certificate as
permitted by Sections 201 or 301, the Trustee shall not be required to
authenticate such Securities if the issuance 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.

             Unless otherwise specified as contemplated by Section 301 with
respect to any series of Securities, or any Tranche thereof, each Security
shall be dated the date of its authentication.

             Unless otherwise specified as contemplated by Section 301 with
respect to any series of Securities, or any Tranche thereof, no Security shall
be entitled to any benefit under this Indenture or be valid or obligatory for
any purpose unless there appears on such Security a certificate of
authentication substantially in the form provided for herein executed by the
Trustee or its agent 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 and is entitled to
the benefits of this Indenture.  Notwithstanding the foregoing, if any Security
shall have been authenticated and delivered hereunder to the Company, or any
Person acting on its behalf, but shall never have been issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided 



                                      -18-
<PAGE>   29

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 hereof.

SECTION 304. TEMPORARY SECURITIES.

             Pending the preparation of definitive Securities of any series, or
any Tranche thereof, the Company may execute, and upon Company Order the
Trustee shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive
Securities in lieu of which they are issued, 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;
provided, however, that temporary Securities need not recite specific
redemption, sinking fund, conversion or exchange provisions.

             Unless otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, or any Tranche thereof, after the
preparation of definitive Securities of such series or Tranche, the temporary
Securities of such series or Tranche shall be exchangeable, without charge to
the Holder thereof, for definitive Securities of such series or Tranche upon
surrender of such temporary Securities at the office or agency of the Company
maintained pursuant to Section 602 in a Place of Payment for such Securities.
Upon such surrender of temporary Securities, the Company shall, except as
aforesaid, execute and the Trustee shall authenticate and deliver in exchange
therefor definitive Securities of the same series and Tranche, of authorized
denominations and of like tenor and aggregate principal amount.

             Until exchanged in full as hereinabove provided, temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and Tranche and of like
tenor authenticated and delivered hereunder.

SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

             The Company shall cause to be kept in each office designated
pursuant to Section 602, with respect to the Securities of each series or any
Tranche thereof, a register (all registers kept in accordance with this Section
being collectively referred to as the "Security Register") in which, subject to
such reasonable regulations as it may prescribe, the Company shall provide for
the registration of Securities of such series or Tranche and the registration
of transfer thereof.  The Company shall designate one Person to maintain the
Security Register for the Securities of each series on a consolidated basis,
and such Person is referred to herein, with respect to such series, as the
"Security Registrar." Anything herein to the contrary notwithstanding, the
Company may designate one or more of its offices as an office in which a
register with respect to the Securities of one or more series, or any Tranche
or Tranches thereof, shall be maintained, and the Company may designate itself
the Security Registrar with respect to one or more of such series.  The
Security Register shall be open for inspection by the Trustee and the Company
at all reasonable times.

             Except as otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, or any Tranche thereof, upon surrender
for registration of transfer of any Security of such series or Tranche at the
office or agency of the Company maintained pursuant to Section 602 in a Place
of Payment for such series or Tranche, the Company shall execute, and the
Trustee shall authenticate and





                                      -19-


<PAGE>   30


deliver, in the name of the designated transferee or transferees, one or more
new Securities of the same series and Tranche, of authorized denominations and
of like tenor and aggregate principal amount.

             Except as otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, or any Tranche thereof, any Security
of such series or Tranche may be exchanged at the option of the Holder, for one
or more new Securities of the same series and Tranche, of authorized
denominations and of like tenor and aggregate principal amount, 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.

             All Securities delivered upon any registration of transfer or
exchange of Securities shall be 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 Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company, the Trustee or
the Security Registrar) be duly endorsed or shall be accompanied by a written
instrument of transfer in form satisfactory to the Company, the Trustee or the
Security Registrar, as the case may be, duly executed by the Holder thereof or
his attorney duly authorized in writing.  Such registration of transfer or
exchange will be effected upon the Company, the Trustee or the Security
Registrar, as the case may be, being satisfied with the documents of title and
identity of the person making the request.

             Unless otherwise specified as contemplated by Section 301 with
respect to Securities of any series, or any Tranche thereof, 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, 406 or 1206 not involving any transfer.

             The Company shall not be required to execute or to provide for the
registration of transfer of or the exchange of (a) Securities of any series, or
any Tranche thereof, during a period beginning at the opening of business 15
days immediately preceding the day of a mailing of a notice of redemption
identifying the serial numbers of the Securities of such series or Tranche
called for redemption and ending at the close of business on the day of such
mailing or (b) any Security so selected for redemption, in whole or in part,
except the unredeemed portion of any Security being redeemed in part.

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

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

             If there shall be delivered to the Company and the Trustee (a)
evidence to their satisfaction of the ownership of and the destruction, loss or
theft of any Security and (b) such security or indemnity as may be reasonably
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
is held by a Person purporting to be the owner of such Security, the Company
shall execute and the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security, a new Security of the same series and


                                      -20-
<PAGE>   31

Tranche, and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

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

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

             Every new Security of any series issued pursuant to this Section
in lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone other than
the Holder of such new Security, and any such new Security shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Securities of such series duly issued hereunder.

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

SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

             Unless otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, or any Tranche thereof, interest on
any Security which is payable, and is punctually paid or duly provided for, on
any Interest Payment Date shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest.

             Subject to Section 312 any interest on any Security of any series
which is payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called "Defaulted Interest") shall forthwith
cease to be payable to the Holder on the related 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 (a) or (b) below:

                   (a) The Company may elect to make payment of any Defaulted
             Interest to the Persons in whose names the Securities of such
             series (or their respective Predecessor Securities) are registered
             at the close of business on a date (herein called 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 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 



                                      -21-
<PAGE>   32

             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 promptly 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 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 Securities of such series
             (or their respective Predecessor Securities) are registered at the
             close of business on such Special Record Date.  The Trustee shall
             be entitled to conclusively rely on the Company's instructions,
             including any list of Holders as it appears in the Security
             Register, with respect to any payment of Defaulted Interest under
             this Section 307.

                   (b) The Company may make payment of any Defaulted Interest
             on the Securities of any series in any other lawful manner not
             inconsistent with the requirements of any securities exchange on
             which such Securities may be listed, and upon such notice as may
             be required by such exchange, if, after notice given by the
             Company to the 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.

             The Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such Security is registered as the
absolute owner of such Security for the purpose of receiving payment of
principal of and premium, if any, and (subject to Sections 305 and 307)
interest, if any, 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.

SECTION 309. CANCELLATION BY SECURITY REGISTRAR.

             All Securities surrendered for payment, redemption, registration
of transfer or exchange shall, if surrendered to any Person other than the
Security Registrar, be delivered to the Security Registrar and, if not
theretofore canceled, shall be promptly canceled by the Security Registrar.
The Company may at any time deliver to the Security Registrar for cancellation
any Securities previously authenticated and delivered hereunder which the
Company may have acquired in any manner whatsoever or which the Company shall
not have issued and sold, and all Securities so delivered shall be promptly
canceled by the Security Registrar.  No Securities shall be authenticated in
lieu of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture.  All canceled Securities held
by the Security Registrar shall be disposed of in accordance with a Company
Order delivered to the Security Registrar and the Trustee, and the Security
Registrar shall promptly deliver a certificate of disposition to the Trustee
and the Company unless, by a Company Order, similarly 



                                      -22-
<PAGE>   33

delivered, the Company shall direct that canceled Securities be returned to it.
The Security Registrar shall promptly deliver evidence of any cancellation of a
Security in accordance with this Section 309 to the Trustee and the Company.

SECTION 310. COMPUTATION OF INTEREST.

             Except as otherwise specified as contemplated by Section 301 for
Securities of any series, or any Tranche thereof, interest on the Securities of
each series shall be computed on the basis of a 360-day year consisting of
twelve 30-day months and on the basis of the actual number of days elapsed
within any month in relation to the deemed 30 days of such month.

SECTION 311. PAYMENT TO BE IN PROPER CURRENCY.

             In the case of the Securities of any series, or any Tranche
thereof, denominated in any currency other than Dollars or in a composite
currency (the "Required Currency"), except as otherwise specified with respect
to such Securities as contemplated by Section 301, the obligation of the
Company to make any payment of the principal thereof, or the premium or
interest thereon, shall not be discharged or satisfied by any tender by the
Company, or recovery by the Trustee, in any currency other than the Required
Currency, except to the extent that such tender or recovery shall result in the
Trustee timely holding the full amount of the Required Currency then due and
payable.  If any such tender or recovery is in a currency other than the
Required Currency, the Trustee may take such actions as it considers
appropriate to exchange such currency for the Required Currency.  The costs and
risks of any such exchange, including without limitation the risks of delay and
exchange rate fluctuation, shall be borne by the Company, the Company shall
remain fully liable for any shortfall or delinquency in the full amount of
Required Currency then due and payable, and in no circumstances shall the
Trustee be liable therefor except in the case of its negligence or willful
misconduct.

SECTION 312. EXTENSION OF INTEREST PAYMENT PERIODS.

             The Company shall have the right at any time, so long as the
Company is not in default in the payment of interest on the Securities of any
series hereunder, to extend interest payment periods on all Securities of one
or more series, or Tranches thereof, if so specified as contemplated by Section
301 with respect to such Securities and upon such terms as may be specified as
contemplated by Section 301 with respect to such securities.

             Securities of any series, or any Tranche thereof, which are

SECTION 402. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

             The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution or an Officer's Certificate.  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 in writing of such Redemption Date and of the principal amount of such
Securities to be redeemed.  In the case of any redemption of Securities (a)
prior to the expiration of any restriction on such redemption provided in the
terms of such Securities or elsewhere in this Indenture or (b) pursuant to an
election of the Company which is subject to a condition specified in the terms
of such Securities, the Company shall furnish the Trustee with an Officer's
Certificate evidencing compliance with such restriction or condition.

SECTION 403. SELECTION OF SECURITIES TO BE REDEEMED.

             If less than all the Securities of any series, or any Tranche
thereof, are to be redeemed, the particular Securities to be redeemed shall be
selected by the Security Registrar from the Outstanding Securities of such
series or Tranche not previously called for redemption, by such method as shall
be provided for any particular series, or, in the absence of any such
provision, by such method of random selection as the Security Registrar shall
deem fair and appropriate and which may, in any case, provide for the selection
for redemption of portions (equal to the minimum authorized denomination for
Securities of such series or Tranche or any integral multiple thereof) of the
principal amount of Securities of such series or Tranche of a denomination
larger than the minimum authorized denomination for Securities of such series
or Tranche; provided, however, that if, as indicated in an Officer's
Certificate, the Company shall have offered to purchase all or any principal
amount of the Securities then Outstanding of any series, or any Tranche
thereof, and less than all of such Securities as to which such offer was made
shall have been tendered to the Company for such purchase, the Security
Registrar, if so directed by Company Order, shall select for redemption all or
any principal amount of such Securities which have not been so tendered.

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

SECTION 404. NOTICE OF REDEMPTION.

             Notice of redemption shall be given in the manner provided in
Section 106 to the Holders of the Securities to be redeemed not less than 30
nor more than 60 days prior to the Redemption Date.

             All notices of redemption shall state:

                   (a) the Redemption Date,

                   (b) the Redemption Price,

                   (c) if less than all the Securities of any series or Tranche
                       are to be redeemed, the 


                                      -24-
<PAGE>   35

             identification of the particular Securities to be redeemed and the
             portion of the principal amount of any Security to be redeemed in
             part,

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

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

                   (f) that the redemption is for a sinking or other fund, if
             such is the case, and

                   (g) such other matters as the Company shall deem desirable or
             appropriate.

             Unless otherwise specified with respect to any Securities in
accordance with Section 301, with respect to any notice of redemption of
Securities at the election of the Company, unless, upon the giving of such
notice, such Securities shall be deemed to have been paid in accordance with
Section 701, such notice may state that such redemption shall be conditional
upon the receipt by the Paying Agent or Agents for such Securities, on or prior
to the date fixed for such redemption, of money sufficient to pay the principal
of and premium, if any, and interest, if any, on such Securities and that if
such money shall not have been so received such notice shall be of no force or
effect and the Company shall not be required to redeem such Securities.  In the
event that such notice of redemption contains such a condition and such money
is not so received, the redemption shall not be made and within a reasonable
time thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Paying Agent or Agents for the Securities
otherwise to have been redeemed shall promptly return to the Holders thereof
any of such Securities which had been surrendered for payment upon such
redemption.

             Notice of redemption of Securities to be redeemed at the election
of the Company, and any notice of non-satisfaction of a condition for
redemption as aforesaid, shall be given by the Company or, at the Company's
request, by the Security Registrar in the name and at the expense of the
Company.  Notice of mandatory redemption of Securities shall be given by the
Security Registrar in the name and at the expense of the Company.

SECTION 405. SECURITIES PAYABLE ON REDEMPTION DATE.

             Notice of redemption having been given as aforesaid, and the
conditions, if any, set forth in such notice having been satisfied, the
Securities or portions thereof so to be redeemed shall, on the Redemption Date,
become due and payable at the Redemption Price therein specified, and from and
after such date (unless, in the case of an unconditional notice of redemption,
the Company shall default in the payment of the Redemption Price and accrued
interest, if any) such Securities or portions thereof, if interest-bearing,
shall cease to bear interest.  Upon surrender of any such Security for
redemption in accordance with such notice, such Security or portion thereof
shall be paid by the Company at the Redemption Price, together with accrued
interest, if any, to the Redemption Date; provided, however, that no such
surrender shall be a condition to such payment if so specified as contemplated
by Section 301 with respect to such Security; and provided, further, that
except as otherwise specified as contemplated by Section 301 with respect to
such Security, any installment of interest on any Security 



                                      -25-
<PAGE>   36

the Stated Maturity of which installment is on or prior to the Redemption Date
shall be payable to the Holder of such Security, or one or more Predecessor
Securities, registered as such at the close of business on the related Regular
Record Date according to the terms of such Security and subject to the
provisions of Section 307.

SECTION 406. SECURITIES REDEEMED IN PART.

             Upon the surrender of any Security which is to be redeemed only in
part at a Place of Payment therefor (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), the Company shall execute,
and the Trustee shall authenticate and deliver to the Holder of such Security,
without service charge, a new Security or Securities of the same series and
Tranche, of any authorized denomination requested by such Holder and of like
tenor and in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

                                 SINKING FUNDS

SECTION 501. APPLICABILITY OF ARTICLE.

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

             The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series, or any Tranche thereof, 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, or any
Tranche thereof, is herein referred to as an "optional sinking fund payment".
If provided for by the terms of Securities of any series, or any Tranche
thereof, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 502.  Each sinking fund payment shall be
applied to the redemption of Securities of the series or Tranche in respect of
which it was made as provided for by the terms of such Securities.

SECTION 502. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

             The Company (a) may deliver to the Paying Agent or Agents
Outstanding Securities (other than any previously called for redemption) of a
series or Tranche in respect of which a mandatory sinking fund payment is to be
made and (b) may apply as a credit Securities of such series or Tranche 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 such mandatory sinking fund payment;
provided, however, that no Securities shall be applied in satisfaction of a
mandatory sinking fund payment if such Securities shall have been previously so
applied.  Securities so applied shall be received and credited for such purpose
by the Paying Agent or Agents at the Redemption Price specified in such
Securities for redemption through operation of the sinking fund and the amount
of such mandatory sinking fund payment shall be reduced accordingly.

SECTION 503. REDEMPTION OF SECURITIES FOR SINKING FUND.

             Not less than 45 days prior to each sinking fund payment date for
the Securities of any series, or any Tranche thereof, the Company shall deliver
to the Paying Agent or Agents an Officer's Certificate specifying:

                   (a) the amount of the next succeeding mandatory sinking fund
             payment for such series or Tranche;

                   (b) the amount, if any, of the optional sinking fund payment
             to be made together with such mandatory sinking fund payment;

                   (c) the aggregate sinking fund payment;

                   (d) the portion, if any, of such aggregate sinking fund
             payment which is to be satisfied by the payment of cash;

                   (e) the portion, if any, of such aggregate sinking fund
             payment which is to be satisfied by delivering and crediting
             Securities of such series or Tranche pursuant to Section 502 and
             stating the basis for such credit and that such Securities have
             not previously been so credited, and the Company shall also
             deliver to the Trustee any Securities to be so delivered.  If the
             Company shall not deliver such Officer's Certificate, the next
             succeeding sinking fund payment for such series or Tranche shall
             be made entirely in cash in the amount of the mandatory sinking
             fund payment.  Not less than 30 days before each such sinking fund
             payment date the Paying Agent or Agents shall select the
             Securities to be redeemed upon such sinking fund payment date in
             the manner specified in Section 403 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 404.  Such notice
             having been duly given, the redemption of such Securities shall be
             made upon the terms and in the manner stated in Sections 405 and
             406.



                                  ARTICLE SIX

                                   COVENANTS


SECTION 601. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

             The Company shall pay the principal of and premium, if any, and
interest, if any, on the Securities of each series in accordance with the terms
of such Securities and this Indenture.

SECTION 602. MAINTENANCE OF OFFICE OR AGENCY.

             The Company shall maintain in each Place of Payment for the
Securities of each series, or any Tranche thereof, an office or agency where
payment of such Securities shall be made, where the registration of transfer or
exchange of such Securities may be effected and where notices and demands to or
upon the Company in respect of such Securities and this Indenture may be
served.  The 
Company 


                                      -27-
<PAGE>   38

shall give prompt written notice to the Trustee of the location, and any change
in the location, of each such office or agency and prompt notice to the Holders
of any such change in the manner specified in Section 106.  If at any time the
Company shall fail to maintain any such required office or agency in respect of
Securities of any series, or any Tranche thereof, or shall fail to furnish the
Trustee with the address thereof, payment of such Securities shall be made,
registration of transfer or exchange thereof may be effected and notices and
demands in respect thereof may be served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent for all such
purposes in any such event.

             The Company may also from time to time designate one or more other
offices or agencies with respect to the Securities of one or more series, or
any Tranche thereof, for any or all of the foregoing purposes and may from time
to time rescind such designations; provided, however, that, unless otherwise
specified as contemplated by Section 301 with respect to the Securities of such
series or Tranche, no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency for such
purposes in each Place of Payment for such Securities in accordance with the
requirements set forth above.  The Company shall give prompt written notice to
the Trustee, and prompt notice to the Holders in the manner specified in
Section 106, of any such designation or rescission and of any change in the
location of any such other office or agency.

             Anything herein to the contrary notwithstanding, any office or
agency required by this Section may be maintained at an office of the Company,
in which event the Company shall perform all functions to be performed at such
office or agency.

SECTION 603. 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 the Securities of any series, or any Tranche thereof, it shall, on
or before each due date of the principal of and premium, if any, and interest,
if any, on any of such Securities, segregate and hold in trust for the benefit
of the Persons entitled thereto a sum sufficient to pay the principal and
premium or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided.  The Company shall
promptly notify the Trustee of any failure by the Company (or any other obligor
on such Securities) to make any payment of principal of or premium, if any, or
interest, if any, on such Securities.

             Whenever the Company shall have one or more Paying Agents for the
Securities of any series, or any Tranche thereof, it shall, on or before each
due date of the principal of and premium, if any, and interest, if any, on such
Securities, deposit with such Paying Agents sums sufficient (without
duplication) to pay the principal and 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 shall promptly notify the Trustee of any failure by it so to act.

             The Company shall cause each Paying Agent for the Securities of
any series, or any Tranche thereof, 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 shall:

                   (a) hold all sums held by it for the payment of the
             principal of and premium, if any, or interest, if any, on such
             Securities in trust for the benefit of the Persons entitled
             thereto until such sums shall be paid to such Persons or otherwise
             disposed of as herein provided;



                                      -28-
<PAGE>   39


                   (b) give the Trustee notice of any failure by the Company
             (or any other obligor upon such Securities) to make any payment of
             principal of or premium, if any, or interest, if any, on such
             Securities; and

                   (c) at any time during the continuance of any such default,
             upon the written request of the Trustee, forthwith pay to the
             Trustee all sums so held in trust by such Paying Agent and furnish
             to the Trustee such information as it possesses regarding the
             names and addresses of the Persons entitled to such sums.

             The Company may at any time 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,
if so stated in a Company Order delivered to the Trustee, in accordance with
the provisions of Article Seven; and, upon such payment by any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability
with respect to such money.

             Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of and premium,
if any, or interest, if any, on any Security and remaining unclaimed for two
years after such principal and premium, if any, or interest has become due and
payable shall be paid to the Company on Company Request, or, if then held by
the Company, shall be discharged from such trust; and, upon such payment or
discharge, the Holder of such Security shall, as an unsecured general creditor
and not as a Holder of an Outstanding Security, look only to the Company for
payment of the amount so due and payable and remaining unpaid, 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 payment to the Company, may at the expense of the Company
cause to be mailed, on one occasion only, notice to such Holder 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 mailing, any unclaimed balance of such
money then remaining will be paid to the Company.

SECTION 604. CORPORATE EXISTENCE.

             Subject to the rights of the Company under Article Eleven, the
Company shall do or cause to be done all things necessary to preserve and keep
in full force and effect its corporate existence.

SECTION 605. MAINTENANCE OF PROPERTIES.

             The Company shall cause (or, with respect to property owned in
common with others, make reasonable effort to cause) all its properties used or
useful in the conduct of its business to be maintained and kept in good
condition, repair and working order and shall cause (or, with respect to
property owned in common with others, make reasonable effort to cause) to be
made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as, in the judgment of the Company, may be necessary
so that the business carried on in connection therewith may be properly
conducted; provided, however, that nothing in this Section shall prevent the
Company from discontinuing, or causing the discontinuance of, the operation and
maintenance of any of its properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business.

SECTION 606. ANNUAL OFFICER'S CERTIFICATE AS TO COMPLIANCE.

             Not later than June 1 in each year, commencing June 1, 1997 the
Company shall deliver to the Trustee an Officer's Certificate which need not
comply with Section 102, executed by the principal executive officer or the
principal financial officer or the principal accounting officer of the Company,
as to such officer's knowledge of the Company's compliance with all conditions
and covenants under this Indenture, such compliance to be determined without
regard to any period of grace or requirement of notice under this Indenture.

SECTION 607. WAIVER OF CERTAIN COVENANTS.

             The Company may omit in any particular instance to comply with any
term, provision or condition set forth in (a) Section 602 or any additional
covenant or restriction specified with respect to the Securities of any series,
or any Tranche thereof, as contemplated by Section 301 if before the time for
such compliance the Holders of at least a majority in aggregate principal
amount of the Outstanding Securities of all series and Tranches with respect to
which compliance with Section 602 or such additional covenant or restriction is
to be omitted, considered as one class, shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition and (b) Section 604, 605, 606 or Article Eleven if
before the time for such compliance the Holders of at least a majority in
principal amount of Securities Outstanding under this Indenture shall, by Act
of such Holders, either waive such compliance in such instance or generally
waive compliance with such term, provision or condition; but, in the case of
(a) or (b), 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.

             to notice of redemption), 602, 603, 907 and 915 and this Article

             satisfaction and discharge of this Indenture, when

                         (i) either

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

                         (iii) the Company has delivered to the Trustee an
                         Officers' Certificate stating that all conditions
                         precedent herein provided for relating to the
                         satisfaction and discharge of this Indenture have been

             series Outstanding hereunder, the Trustee shall be required to
             execute an instrument acknowledging satisfaction and discharge of
             this Indenture only if requested to do so with respect to
             Securities of all series as to which it is Trustee and if the
             other conditions thereto as required herein are met.  In the event
             there shall be two or more Trustees hereunder, then the
             effectiveness of each such instrument from each Trustee hereunder
             shall be conditioned upon receipt of such instruments from each
             other Trustee hereunder.

             provided in this Section 701, the Trustee shall assign, transfer

SECTION 702.  LEGAL AND COVENANT DEFEASANCE.

                   (a) On and after the date the Company shall have fulfilled
             the conditions of Section 702(c), it shall be deemed to have paid
             and discharged the entire indebtedness represented by any Security
             or Securities of any series or Tranche, or any portion of the
             principal amount thereof, and satisfied its obligations under this
             Indenture with respect thereto (hereinafter, "Legal Defeasance").
             Such Securities shall thereafter be deemed to be "Outstanding"
             solely for the purposes of Section 703 hereof and the following
             provisions of this Indenture shall survive with respect thereto:
             (i) the rights of Holders of such Securities to receive, solely
             from the trust fund described in Section 702(c), payments in
             respect of the principal of, premium, if any, and interest on such
             Securities when such payments are due, or on the redemption date,
             as the case may be, and (ii) the obligations of the Company and
             the Trustee with respect to such Securities under Sections 304,
             305, 306, 404, 503 (as to notice of redemption), 602, 603, 907 and
             915 and this Article Seven.  The Company may elect to effect a
             Legal Defeasance under this Section 702(a) notwithstanding the
             prior election to effect a Covenant Defeasance under Section
             702(b) with respect to Securities or portions thereof of the same
             series or Tranche.

                   (b) The Company shall be released from its obligations under
             the covenants contained in Sections 604 (except with respect to
             maintaining its corporate existence), 605 and 606 and Article
             Eleven with respect to any Security or Securities of any series or
             Tranche or any portion of the principal amount thereof (and under
             any covenants inserted pursuant to Section 301(v), in any
             supplemental indenture, Board Resolution or Officers' Certificate
             establishing such Security), on and after the date the conditions
             in Section 702(c) are satisfied (hereinafter, "Covenant
             Defeasance").  Such Securities or portions thereof shall
             thereafter be deemed not "Outstanding" for the purposes of any
             direction, waiver, consent or declaration or Act of Holders (and
             the consequences of any thereof) in connection with such
             covenants, but shall continue to be deemed "Outstanding" for all
             other purposes hereunder.

             In the event of a Covenant Defeasance, 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 covenant, whether
             directly or indirectly, by reason of any reference elsewhere herein
             to any such covenant or by reason of any reference in any such
             covenant to any other provision herein or in any other document and
             such omission to comply shall not constitute a Default or an Event
             of Default under Section 801(c) with respect to such Securities or
             portions thereof, but, except as specified above, the remainder of
             this Indenture and such Securities or portions thereof shall
             continue to be in full force and effect.

                   (c) The following shall be the conditions to any defeasance
             under this Section 702:

                         (i) there shall have been irrevocably deposited with
                   the Trustee, in trust:  (1) money in an amount which shall
                   be sufficient, or (2) Eligible Obligations, which shall not
                   contain provisions permitting the redemption or other
                   prepayment thereof at the option of the issuer thereof, the
                   principal of and the interest on which when due, without any
                   regard to reinvestment thereof will provide moneys which,
                   together with the money, if any, deposited with or held by
                   the Trustee, shall be sufficient, or (3) a combination of
                   (1) or (2) which shall be sufficient, to pay when due the
                   principal of and premium, if any, and interest, if any, due
                   and to become due on such Securities or portions thereof;
                   provided, however, that (x) in the case of the provision for
                   payment or redemption of less than all the Securities of any
                   series or Tranche, such Securities or portions thereof shall
                   have been selected by the Security Registrar as provided
                   herein and, in the case of a redemption, the notice
                   requisite to the validity of such redemption shall have been
                   given or irrevocable authority shall have been given by the
                   Company to the Trustee to give such notice, under
                   arrangements satisfactory to the Trustee and (y) such money
                   or the proceeds of such Eligible Obligations shall either
                   (i) have been on deposit with the Trustee for a period of at
                   least 90 days, or (ii) the Trustee shall have received an
                   Opinion of Counsel reasonably satisfactory in form to the
                   Trustee to the effect that payments to Holders with such
                   moneys as proceeds are not recoverable as a preference under
                   any applicable United States federal or state law relating
                   to bankruptcy, insolvency, receivership, winding-up,
                   liquidation, reorganization or relief of debtors;

                                (ii) if such deposit shall have been made prior
                   to the Maturity of such Securities, the Company shall have
                   delivered to the Trustee a Company Order stating that the
                   money and Eligible Obligations deposited with the Trustee in
                   accordance with this Section shall be held by the Trustee,
                   in trust, as provided in Section 703;

                                (iii) if Eligible Obligations shall have been
                   deposited with the Trustee, the Company shall have delivered
                   to the Trustee an opinion of an independent public
                   accountant of nationally recognized standing, selected by
                   the Company, to the effect that the requirements set forth
                   in clause (i) above have been satisfied;

                                (iv) the Company shall have delivered to the
                   Trustee an Opinion of Counsel in the form described in
                   Section 702(d);

                                (v) the Company shall have delivered to the
                   Trustee an Officers' Certificate stating that all conditions
                   precedent herein relating to either the Legal Defeasance
                   under

                   Section 702(a) or the Covenant Defeasance under Section
                   702(b), as the case may be, have been complied with; and

                                (vi) the deposit shall not result in the
                   Company, the Trustee or the trust being deemed an
                   "investment company" under the Investment Company Act of
                   1940, as amended.

                   (d) (i) In the case of Legal Defeasance under Section
             702(a), there shall also be delivered to the Trustee either (x) an
             Opinion of Counsel in a form reasonably satisfactory to the
             Trustee to the effect that, based upon (A) an accompanying ruling
             of the Internal Revenue Service issued to the Company, or (B) a
             change in law or regulation occurring after the date hereof, the
             Holders will not realize income, gain or loss for federal income
             tax purposes as a result of such Legal Defeasance but will realize
             income, gain or loss on the Securities, including payments of
             interest thereon, in the same amounts, in the same manner and at
             the same times as would have been the case if such Legal
             Defeasance had not occurred, or (y) an instrument, in form
             reasonably satisfactory to the Trustee, wherein the Company,
             notwithstanding the payment and discharge, pursuant to Section
             702(a) and (e), of its indebtedness in respect of Securities of
             any series, or any portion of the principal amount thereof, shall
             assume the obligation (which shall be absolute and unconditional)
             to irrevocably deposit with the Trustee such additional sums of
             money, if any, or additional Eligible Obligations (meeting the
             requirements of subsection (c)(i) hereof), if any, or any
             combination thereof, at such time or times, as shall be necessary,
             together with the money and/or Eligible Obligations theretofore so
             deposited, to pay when due the principal of and premium, if any,
             and interest due and to become due on such Securities or portions
             thereof; provided, however, that such instrument may state that
             the obligation of the Company to make additional deposits as
             aforesaid shall be subject to the delivery to the Company by the
             Trustee of a notice asserting the deficiency accompanied by an
             opinion of an independent public accountant of nationally
             recognized standing, selected by the Trustee, showing the
             calculation thereof ; and

                                (ii)  In the case of Covenant Defeasance under
                   Section 702(b), there shall also be delivered to the Trustee
                   an Opinion of Counsel in a form reasonably satisfactory to
                   the Trustee to the effect that the Holders will not realize
                   income, gain or loss for Federal income tax purposes as a
                   result of such Covenant Defeasance but will realize income,
                   gain or loss on the Securities, including payments of
                   interest thereon, in the same amounts, in the same manner
                   and at the same times as would have been the case if such
                   Covenant Defeasance had not occurred.

                   (e) In the event that the Company effects a Legal
             Defeasance, upon receipt by the Trustee of money or Eligible
             Obligations, or both, in accordance with Section 702(c), together
             with the documents required by such paragraph, the Trustee shall,
             upon receipt of a Company Request, acknowledge in writing that the
             Security or Securities or portions thereof with respect to which
             such deposit was made are deemed to have been paid for all
             purposes of this Indenture and that the entire indebtedness of the
             Company in respect thereof is deemed to have been satisfied and
             discharged.

                   (f) If payment of less than all of the Securities of any
             series, or any Tranche thereof, is to be provided for in the
             manner and with the effect provided in this Section, the Security
             Registrar shall select such Securities, or portions of principal
             amount thereof in the manner





                                      -33-
<PAGE>   44
             specified by Section 403 for selection for redemption of less than
             all the Securities of a series or Tranche.

                   (g) In the event that Securities which shall be deemed to
             have been paid as a result of a Legal Defeasance (or with respect
             to which a Covenant Defeasance has been effected) do not mature
             and are not to be redeemed within the 60-day period commencing
             with the date of the deposit with the Trustee of moneys or
             Eligible Obligations, the Company shall, as promptly as
             practicable, give a notice, in the same manner as a notice of
             redemption with respect to such Securities, to the Holders of such
             Securities to the effect that such deposit has been made and the
             effect thereof.

                   (h) The Company shall pay, and shall indemnify the Trustee
             and each Holder of Securities which are deemed to have been paid
             as provided in this Section against any tax, fee or other charge
             imposed on or assessed against the Eligible Obligations deposited
             with the Trustee or the principal or interest received by the
             Trustee in respect of such Eligible Obligations.

                   (i) Anything herein to the contrary notwithstanding, if, at
             any time after a Legal Defeasance or a Covenant Defeasance is
             effected pursuant to this Section (without regard to the
             provisions of this paragraph (i)), the Trustee shall be required
             to return the money or Eligible Obligations, or combination
             thereof, deposited with it to the Company or its representative
             under any applicable federal or state bankruptcy, insolvency or
             other similar law, the indebtedness of the Company in respect of
             such Security shall thereupon be deemed retroactively not to have
             been satisfied and discharged, as aforesaid, and to remain
             Outstanding, or, as the case may be,  the obligations under the
             above-mentioned covenants in respect of such Security shall
             thereupon be deemed retroactively not to have been released.

SECTION 703.  APPLICATION OF TRUST MONEY.

             Neither the Eligible Obligations nor the money deposited with the
Trustee pursuant to Section 702(c)(i), nor the principal or interest payments
on any such Eligible Obligations, shall be withdrawn or used for any purpose
other than, and shall be held in trust for, the payment of the principal of and
premium, if any, and interest, if any, on the Securities or portions of
principal amount thereof in respect of which such deposit was made, all
subject, however, to the provisions of Section 603; provided, however, that, so
long as there shall not have occurred and be continuing an Event of Default,
any cash received from such principal or interest payments on such Eligible
Obligations deposited with the Trustee, if not then needed for such purpose,
shall, to the extent practicable, be invested in Eligible Obligations of the
type described in Section 702(c)(i)(2) maturing at such times and in such
amounts as shall be sufficient to pay when due the principal of and premium, if
any, and interest, if any, due and to become due on such Securities or portions
thereof on and prior to the Maturity thereof, and interest earned from such
reinvestment shall be paid over to the Company as received by the Trustee, free
and clear of any trust, lien or pledge under this Indenture except the lien
provided by Section 907; and provided, further, that, so long as there shall
not have occurred and be continuing an Event of Default, any moneys held by the
Trustee in accordance with this Section on the Maturity of all such Securities
in excess of the amount required to pay the principal of and premium, if any,
and interest, if any, then due on such Securities shall be paid over to the
Company free and clear of any trust, lien or pledge under this Indenture except
the lien provided by Section 907.

                          EVENTS OF DEFAULT; REMEDIES


SECTION 801. EVENTS OF DEFAULT.

             "Event of Default", wherever used herein with respect to
Securities of any series, means any one of the following events:

                   (a) failure to pay interest, if any, on any Security of such
             series within sixty (60) days after the same becomes due and
             payable (whether or not payment is prohibited by the provisions of
             Article Fifteen hereof); provided, however, that a valid extension
             of the interest payment period by the Company as contemplated in
             Section 312 of this Indenture shall not constitute a failure to
             pay interest for this purpose; or

                   (b) failure to pay the principal of or premium, if any, on
             any Security of such series within three (3) Business Days after
             its Maturity (whether or not payment is prohibited by the
             provisions of Article Fifteen hereof); or

                   (c) failure to perform or breach of any covenant or warranty
             of the Company in this Indenture (other than a covenant or
             warranty a default in the performance of which or breach of which
             is elsewhere in this Section specifically dealt with or which has
             expressly been included in this Indenture solely for the benefit
             of one or more series of Securities other than such series) for a
             period of 60 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 33% in principal amount
             of the Outstanding Securities of such series, a written notice
             specifying such default or breach and requiring it to be remedied
             and stating that such notice is a "Notice of Default" hereunder,
             unless the Trustee, or the Trustee and the Holders of a principal
             amount of Securities of such series not less than the principal
             amount of Securities the Holders of which gave such notice, as the
             case may be, shall agree in writing to an extension of such period
             prior to its expiration; provided, however, that the Trustee, or
             the Trustee and the Holders of such principal amount of Securities
             of such series, as the case may be, shall be deemed to have agreed
             to an extension of such period if corrective action is initiated
             by the Company within such period and is being diligently pursued;
             or

                   (d) the entry by a court having jurisdiction in the premises
             of (1) 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 (2) a decree or order adjudging the Company a bankrupt or
             insolvent, or approving as properly filed a petition by one or
             more Persons other than the Company 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 for the Company or for any substantial
             part of its property, or ordering the winding up or liquidation of
             its affairs, and any such decree or order for relief or any such
             other decree or order shall have remained unstayed and in effect
             for a period of 90 consecutive days; or

<PAGE>   46
                   (e) 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 a case or proceeding under any
             applicable Federal or State bankruptcy, insolvency, reorganization
             or other similar law or to the commencement of any bankruptcy or
             insolvency case or proceeding against it, or the filing by it of a
             petition or answer or consent seeking reorganization or relief
             under any applicable Federal or State law, or the consent by it to
             the filing of such petition or to the appointment of or taking
             possession by a custodian, receiver, liquidator, assignee,
             trustee, sequestrator or 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 authorization of such action by the Board of
             Directors; or

                   (f) any other Event of Default specified with respect to
             Securities of such series.


SECTION 802. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

             If an Event of Default shall have occurred and be continuing with
respect to Securities of any series at the time Outstanding, then in every such
case the Trustee or the Holders of not less than 33% in principal amount of the
Outstanding Securities of such series may declare the principal amount (or, if
any of the Securities of such series are Discount Securities, such portion of
the principal amount of such Securities as may be specified in the terms
thereof as contemplated by Section 301) of all of the Securities of such 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 receipt by the Company of notice
of such declaration such principal amount (or specified amount) shall become
immediately due and payable (provided that the payment of principal of such
securities shall remain subordinated to the extent provided in Article Fifteen
hereof); provided, however, that if an Event of Default shall have occurred and
be continuing with respect to more than one series of Securities, the Trustee
or the Holders of not less than 33% in aggregate principal amount of the
Outstanding Securities of all such series, considered as one class, may make
such declaration of acceleration, and not the Holders of the Securities of any
one of such series.

             At any time after such a declaration of acceleration with respect
to Securities of any series shall have been made and before a judgment or
decree for payment of the money due shall have been obtained by the Trustee as
hereinafter in this Article provided, the Event or Events of Default giving
rise to such declaration of acceleration shall, without further act, be deemed
to have been waived, and such declaration and its consequences shall, without
further act, be deemed to have been rescinded and annulled, if

                   (a) the Company shall have paid or deposited with the Trustee
             a sum sufficient to pay

                         (1) all overdue interest on all Securities of such
                             series;

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





                                      -36-

<PAGE>   47
                         (3) to the extent that payment of such interest is
                   lawful, interest upon overdue interest at the rate or rates
                   prescribed therefor in such Securities;

                         (4) all amounts due to the Trustee under Section 907;
                   and

                   (b) any other Event or Events of Default with respect to
             Securities of such series, other than the non-payment of the
             principal of Securities of such series which shall have become due
             solely by such declaration of acceleration, shall have been cured
             or waived as provided in Section 813.

No such rescission shall affect any subsequent Event of Default or impair any
right consequent thereon.

SECTION 803. COLLECTION OF INDEBTEDNESS AND SUITS FOR
                         ENFORCEMENT BY TRUSTEE.

             If an Event of Default described in clause (a) or (b) of Section
801 shall have occurred and be continuing, the Company shall, upon demand of
the Trustee, pay to it, for the benefit of the Holders of the Securities of the
series with respect to which such Event of Default shall have occurred, the
whole amount then due and payable on such Securities for principal and premium,
if any, and interest, if any, and, to the extent permitted by law, interest on
premium, if any, and on any overdue principal and interest, at the rate or
rates prescribed therefor in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover any amounts due to the Trustee
under Section 907.

             If the Company shall fail 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
shall have occurred and be continuing, the Trustee may in its discretion
proceed to protect and enforce its rights and the rights of the Holders of
Securities of such series by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement 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 804. TRUSTEE MAY FILE PROOFS OF CLAIM.

             In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition
or other judicial proceeding relative to the Company or any other obligor upon
the Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

                   (a) to file and prove a claim for the whole amount of
             principal, premium, if any, and interest, if any, owing and unpaid
             in respect of the Securities and to file such other papers





                                      -37-
<PAGE>   48
             or documents as may be necessary or advisable in order to have the
             claims of the Trustee (including any claim for amounts due to the
             Trustee under Section 907) and of the Holders allowed in such
             judicial proceeding, and

                   (b) 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 amounts due it under Section 907.

             Nothing herein contained 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.

SECTION 805. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

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

SECTION 806. APPLICATION OF MONEY COLLECTED.

             Subject to the provisions of Article Fifteen, any money collected
by the Trustee pursuant to this Article shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal or premium, if any, or
interest, if any, upon presentation of the Securities in respect of which or
for the benefit of which such money shall have been collected 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 907;

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

                   Third: To the Company.

SECTION 807. LIMITATION ON SUITS.

             No Holder 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:

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

                   (b) the Holders of not less than a majority in aggregate
             principal amount of the Outstanding Securities of all series in
             respect of which an Event of Default shall have occurred and be
             continuing, considered as one class, 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;

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

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

                   (e) no direction inconsistent with such written request
             shall have been given to the Trustee during such 60-day period by
             the Holders of a majority in aggregate principal amount of the
             Outstanding Securities of all series in respect of which an Event
             of Default shall have occurred and be continuing, considered as
             one class;

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

SECTION 808. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
             INTEREST.

             Notwithstanding any other provision in this Indenture, the Holder
of any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and premium, if any, and (subject to
Section 307 and 312) interest, if any, on such Security on the Stated Maturity
or Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

SECTION 809. RESTORATION OF RIGHTS AND REMEDIES.

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

SECTION 810. RIGHTS AND REMEDIES CUMULATIVE.

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

SECTION 811. DELAY OR OMISSION NOT WAIVER.

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

SECTION 812. CONTROL BY HOLDERS OF SECURITIES.

             If an Event of Default shall have occurred and be continuing in
respect of a series of Securities, the Holders of a majority in principal
amount of the Outstanding Securities of such 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, however, that
if an Event of Default shall have occurred and be continuing with respect to
more than one series of Securities, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of all such series, considered
as one class, shall have the right to make such direction, and not the Holders
of the Securities of any one of such series; and provided, further, that

                   (a) such direction shall not be in conflict with any rule of
             law or with this Indenture, and could not involve the Trustee in
             personal liability in circumstances where indemnity would not, in
             the Trustee's sole discretion, be adequate, and

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

SECTION 813. WAIVER OF PAST DEFAULTS.

             The Holders of not less than 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 such
series and its consequences, except a default

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

                   (b) in respect of a covenant or provision hereof which under
             Section 1202 cannot be modified or amended without the consent of
             the Holder of each Outstanding Security of such series affected.





                                      -40-
<PAGE>   51
             Upon any such waiver, such default shall cease to exist, and any
and all Events 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 814. UNDERTAKING FOR COSTS.

             The Company and the Trustee agree, and each Holder by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may
in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in
aggregate principal amount of the Outstanding Securities of all series in
respect of which such suit may be brought, considered as one class, or to any
suit instituted by any Holder for the enforcement of the payment of the
principal of or premium, if any, or interest, if any, on any Security on or
after the Stated Maturity or Maturities expressed in such Security (or, in the
case of redemption, on or after the Redemption Date).

SECTION 815. 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 or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (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 NINE

                                  THE TRUSTEE


SECTION 901. CERTAIN DUTIES AND RESPONSIBILITIES.

                   (a) Except during the continuance of an Event of Default
              with respect to Securities of any series,

                         (1) the Trustee undertakes to perform, with respect to
                   Securities of such series, such duties and only such duties
                   as are specifically set forth in this Indenture, and no
                   implied covenants or obligations shall be read into this
                   Indenture against the Trustee; and

                         (2) in the absence of bad faith on its part, the
                   Trustee may, with respect to Securities of such series,
                   conclusively rely, as to the truth of the statements and the
                   correctness of the opinions expressed therein, upon
                   certificates or opinions furnished 





                                      -41-
<PAGE>   52


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

                   (b) In case an Event of Default with respect to Securities
             of any series shall have occurred and be continuing, the Trustee
             shall exercise, with respect to Securities of such series, such of
             the rights and powers vested in it by this Indenture, and use the
             same degree of care and skill in their exercise, as a prudent man
             would exercise or use under the circumstances in the conduct of
             his own affairs.

                   (c) No provision of this Indenture shall be construed to
             relieve the Trustee from liability for its own negligent action,
             its own negligent failure to act, or its own wilful misconduct,
             except that

                         (1) this subsection shall not be construed to limit
                   the effect of subsection (a) of this Section;

                         (2) the Trustee shall not be liable for any error of
                   judgment made in good faith by a Responsible Officer, unless
                   it shall be proved that the Trustee was negligent in
                   ascertaining the pertinent facts;

                         (3) the Trustee shall not be liable with respect to
                   any action taken or omitted to be taken by it in good faith
                   in accordance with the direction of the Holders of a
                   majority in principal amount of the Outstanding Securities
                   of any one or more series, as provided herein, relating to
                   the time, method and place of conducting any proceeding for
                   any remedy available to the Trustee, or exercising any trust
                   or power conferred upon the Trustee, under this Indenture
                   with respect to the Securities of such series; and

                         (4) 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.

                   (d) 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 902. NOTICE OF DEFAULTS.

             The Trustee shall give the Holders notice of any default hereunder
with respect to the Securities of any series to the Holders of Securities of
such series in the manner and to the extent required to do so by the Trust
Indenture Act, unless such default shall have been cured or waived; provided,
however, that in the case of any default of the character specified in Section
801(c), no such notice to Holders shall be given until at least 75 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.

             direction, consent, order, bond, debenture, note, other evidence
             of indebtedness or other paper or document believed by it to be

             or parties;

                   (b) any request or direction of the Company mentioned herein

             by a Board Resolution;

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

                   (d) the Trustee may consult with counsel and the written

             unless such Holder 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;

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

             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 (subject to applicable legal requirements) be entitled to
             examine, during normal business hours, the books, records and
             premises of the Company, personally or by agent or attorney;

                   (g) the Trustee may execute any of the trusts or powers

                   (h) except as otherwise provided in Section 801, the Trustee
             shall not be charged with knowledge of any Event of Default with
             respect to the Securities of any series for which it is acting as
             Trustee unless either (1) a Responsible Officer of the Trustee
             shall have actual knowledge of the Event of Default or (2) written
             notice of such Event of Default shall have

SECTION 904. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
                         SECURITIES.

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

SECTION 905. MAY HOLD SECURITIES.

             Each of 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, subject
to Sections 908 and 913, may otherwise deal with the Company with the same
rights it would have if it were not the Trustee, Authenticating Agent, Paying
Agent, Security Registrar or such other agent.

SECTION 906. 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 investment of any money received by
it hereunder except as expressly provided herein or otherwise agreed with, and
for the sole benefit of, the Company.

SECTION 907. COMPENSATION AND REIMBURSEMENT.

             The Company shall

                   (a) 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);

                   (b) except as otherwise expressly provided herein, reimburse
             the Trustee upon its request for all reasonable expenses,
             disbursements and advances reasonably 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 to the extent
             that any such expense, disbursement or advance may be attributable
             to its negligence, wilful misconduct or bad faith; and

                   (c) indemnify the Trustee and hold it harmless from and
             against, any loss, liability or expense reasonably incurred by it
             arising out of or in connection with the acceptance or
             administration of the trust or trusts hereunder or the performance
             of its duties 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, except

<PAGE>   55
             to the extent any such loss, liability or expense may be
             attributable to its negligence, wilful misconduct or bad faith.

             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 other than
property and funds held in trust under Section 703 (except as otherwise
provided in Section 703).  "Trustee" for purposes of this Section shall include
any predecessor Trustee; provided, however, that the negligence, wilful
misconduct or bad faith of any Trustee hereunder shall not affect the rights of
any other Trustee hereunder.

SECTION 908. DISQUALIFICATION; CONFLICTING INTERESTS.

             If the Trustee shall have or acquire any conflicting interest
within the meaning of the Trust Indenture Act, it shall either eliminate such
conflicting interest or resign to the extent, in the manner and with the
effect, and subject to the conditions, provided in the Trust Indenture Act and
this Indenture.  For purposes of Section 310(b)(1) of the Trust Indenture Act
and to the extent permitted thereby, the Trustee, in its capacity as trustee in
respect of the Securities of any series, shall not be deemed to have a
conflicting interest arising from its capacity as trustee in respect of the
Securities of any other series.

SECTION 909. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

             There shall at all times be a Trustee hereunder which shall be

                   (a) a corporation organized and doing business under the
             laws of the United States, any State or Territory 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 and subject to supervision or examination by
             Federal or State authority, or

                   (b) if and to the extent permitted by the Commission by
             rule, regulation or order upon application, a corporation or other
             Person organized and doing business under the laws of a foreign
             government, authorized under such laws to exercise corporate trust
             powers, having a combined capital and surplus of at least
             $50,000,000 or the Dollar equivalent of the applicable foreign
             currency and subject to supervision or examination by authority of
             such foreign government or a political subdivision thereof
             substantially equivalent to supervision or examination applicable
             to United States institutional trustees,

and, in either case, qualified and eligible under this Article and the Trust
Indenture Act.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of such 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.

SECTION 910. 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 911.





                                      -45-
<PAGE>   56
                   (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 911 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 908
                   after written request therefor by the Company or by any
                   Holder who has been a bona fide Holder for at least six
                   months, or

                         (2) the Trustee shall cease to be eligible under
                   Section 909 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 any
                   public officer shall take charge or control of the Trustee
                   or of its property or affairs for the purpose of
                   rehabilitation, conservation or liquidation,

then, in any such case, (x) the Company by a Board Resolution may remove the
Trustee with respect to all Securities or (y) subject to Section 814, any
Holder who has been a bona fide Holder 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
             Trustee for any cause (other than as contemplated in clause (y) in
             subsection (d) of this Section), 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 of such series and that at any
             time there shall be only one Trustee with respect to the
             Securities of any particular series) and shall comply with the
             applicable requirements of Section 911.  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 911, 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 and
             accepted appointment in the manner required by Section 911, any
             Holder who has been a bona fide Holder of a Security 


                                      -46-
<PAGE>   57

             of such series for at least six months may, on behalf of itself 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.

                   (f) So long as no event which is, or after notice or lapse
             of time, or both, would become, an Event of Default shall have
             occurred and be continuing, and except with respect to a Trustee
             appointed by Act of the Holders of a majority in principal amount
             of the Outstanding Securities pursuant to subsection (e) of this
             Section, if the Company shall have delivered to the Trustee (i) a
             Board Resolution appointing a successor Trustee, effective as of a
             date specified therein, and (ii) an instrument of acceptance of
             such appointment, effective as of such date, by such successor
             Trustee in accordance with Section 911, the Trustee shall be
             deemed to have resigned as contemplated in subsection (b)of this
             Section, the successor Trustee shall be deemed to have been
             appointed by the Company pursuant to subsection (e) of this
             Section and such appointment shall be deemed to have been accepted
             as contemplated in Section 911, all as of such date, and all other
             provisions of this Section and Section 911 shall be applicable to
             such resignation, appointment and acceptance except to the extent
             inconsistent with this subsection (f).

                   (g) 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 by mailing written notice of such
             event by first-class mail, postage prepaid, to all Holders of
             Securities of such series as their names and addresses appear in
             the Security Register.  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 911. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

                   (a) In case of the appointment hereunder of a successor
             Trustee with respect to the Securities of all series, 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 any further act, deed or conveyance,
             shall become vested with all the rights, powers, trusts and duties
             of the retiring Trustee; but, on the request of the Company or the
             successor Trustee, such retiring Trustee shall, upon payment of
             all sums owed to it, 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.

                   (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 


                                      -47-
<PAGE>   58

             necessary or desirable to confirm that all the rights, powers,
             trusts and duties of the retiring Trustee with respect to the
             Securities of that or those series as to which the retiring Trustee
             is not retiring shall continue to be vested in the retiring Trustee
             and (3) shall add to or change any of the provisions of this
             Indenture as shall be necessary to provide for or facilitate the
             administration of the trusts hereunder by more than one Trustee, it
             being understood that nothing herein or in such supplemental
             indenture shall constitute such Trustees co-trustees of the same
             trust and that each such Trustee shall be trustee of a trust or
             trusts hereunder separate and apart from any trust or trusts
             hereunder administered by any other such Trustee; and upon the
             execution and delivery of such supplemental indenture the
             resignation or removal of the retiring Trustee shall become
             effective to the extent provided therein and each such successor
             Trustee, without any further act, deed or conveyance, shall become
             vested with all the rights, powers, trusts and duties of the
             retiring Trustee with respect to the Securities of that or those
             series to which the appointment of such successor Trustee relates;
             but, on request of the Company or any successor Trustee, such
             retiring Trustee, upon payment of all sums owed to it, 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 such successor Trustee, the Company
             shall execute any instruments which fully vest in and confirm to
             such successor Trustee all such rights, powers and trusts referred
             to in subsection (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 912. 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 913. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

             If the Trustee shall be or become a creditor of the Company or any
other obligor upon the Securities (other than by reason of a relationship
described in Section 311(b) of the Trust Indenture Act), the Trustee shall be
subject to any and all applicable provisions of the Trust Indenture Act
regarding the collection of claims against the Company or such other obligor.
For purposes of Section 311(b) of the Trust Indenture Act:

                   (a) the term "cash transaction" means any transaction in
             which full payment for goods or securities sold is made within
             seven days after delivery of the goods or securities in





                                      -48-
<PAGE>   59


             currency or in checks or other orders drawn upon banks or bankers
             and payable upon demand;

                   (b) the term "self-liquidating paper" means any draft, bill
             of exchange, acceptance or obligation which is made, drawn,

             the purchase, processing, manufacturing, shipment, storage or sale
             of goods, wares or merchandise and which is secured by documents
             evidencing title to, possession of, or a lien upon, the goods,
             wares or merchandise or the receivables or proceeds arising from
             the sale of the goods, wares or merchandise previously
             constituting the security, provided the security is received by
             the Trustee simultaneously with the creation of the creditor
             relationship with the Company arising from the making, drawing,
             negotiating or incurring of the draft, bill of exchange,
             acceptance or obligation.

SECTION 914. CO-TRUSTEES AND SEPARATE TRUSTEES.

             At any time or times, for the purpose of meeting the legal
requirements of any applicable jurisdiction, the Company and the Trustee shall
have power to appoint, and, upon the written request of the Trustee or of the
Holders of at least thirty-three per centum (33%) in principal amount of the
Securities then outstanding, the Company shall for such purpose join with the
Trustee in the execution and delivery of all instruments and agreements
necessary or proper to appoint, one or more Persons approved by the Trustee
either to act as co-trustee, jointly with the Trustee, or to act as separate
trustee, in either case with such powers as may be provided in the instrument
of appointment, and to vest in such Person or Persons, in the capacity
aforesaid, any property, title, right or power deemed necessary or desirable,
subject to the other provisions of this Section.  If the Company does not join
in such appointment within 15 days after the receipt by it of a request so to
do, or if an Event of Default shall have occurred and be continuing, the
Trustee alone shall have power to make such appointment.

             Should any written instrument or instruments from the Company be
required by any co-trustee or separate trustee so appointed to more fully
confirm to such co-trustee or separate trustee such property, title, right or
power, any and all such instruments shall, on request, be executed,
acknowledged and delivered by the Company.

             Every co-trustee or separate trustee shall, to the extent
permitted by law, but to such extent only, be appointed subject to the
following conditions:

                   (a) the Securities shall be authenticated and delivered, and
             all rights, powers, duties and obligations hereunder in respect of
             the custody of securities, cash and other personal property held
             by, or required to be deposited or pledged with, the Trustee
             hereunder, shall be exercised solely, by the Trustee;

                   (b) the rights, powers, duties and obligations hereby
             conferred or imposed upon the Trustee in respect of any property
             covered by such appointment shall be conferred or imposed upon and
             exercised or performed either by the Trustee or by the Trustee and
             such co-trustee or separate trustee jointly, as shall be provided
             in the instrument appointing such co-trustee or separate trustee,
             except to the extent that under any law of any jurisdiction in
             which any particular act is to be performed, the Trustee shall be
             incompetent or unqualified to perform such act, in which event
             such rights, powers, duties and obligations shall be exercised and
             performed by such co-trustee or separate trustee;





                                      -49-
<PAGE>   60
                   (c) the Trustee at any time, by an instrument in writing
             executed by it, with the concurrence of the Company, may accept
             the resignation of or remove any co-trustee or separate trustee
             appointed under this Section, and, if an Event of Default shall
             have occurred and be continuing, the Trustee shall have power to
             accept the resignation of, or remove, any such co-trustee or
             separate trustee without the concurrence of the Company.  Upon the
             written request of the Trustee, the Company shall join with the
             Trustee in the execution and delivery of all instruments and
             agreements necessary or proper to effectuate such resignation or
             removal.  A successor to any co-trustee or separate trustee so
             resigned or removed may be appointed in the manner provided in
             this Section;

                   (d) no co-trustee or separate trustee hereunder shall be
             personally liable by reason of any act or omission of the Trustee,
             or any other such trustee hereunder; and

                   (e) any Act of Holders delivered to the Trustee shall be
             deemed to have been delivered to each such co-trustee and separate
             trustee.

SECTION 915. APPOINTMENT OF AUTHENTICATING AGENT.

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

             Any corporation into which an Authenticating Agent may be merged
or converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an 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 the Authenticating Agent.

             An Authenticating Agent may 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 



                                      -50-
<PAGE>   61

receiving such a notice of resignation or upon such a termination, or in case at
any time such Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company.  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 payments, in accordance
with, and subject to the provisions of Section 907.

             The provisions of Sections 308, 904 and 905 shall be applicable to
each Authenticating Agent.

             If an appointment with respect to the Securities of one or more
series, or any Tranche thereof, shall be made pursuant to this Section, the
Securities of such series or Tranche may have endorsed thereon, in addition to
the Trustee's certificate of authentication, an alternate certificate of
authentication substantially in the following form:

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

                                              Authorized Signatory


             If all of the Securities of a series may not be originally issued
at one time, and if 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 and in
accordance with such procedures as shall be acceptable to the Trustee, an
Authenticating Agent having an office in a Place of Payment designated by the
Company with respect to such series of Securities.

             With the consent of the Holders of not less than a majority in
aggregate principal amount of the Securities of all series then Outstanding
under this Indenture, considered as one class, by Act of said Holders delivered
to the Company and the Trustee, the Company, when authorized by a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to, or changing in
any manner or eliminating any of the provisions of, this Indenture; provided,
however, that if there shall be Securities of more than one series Outstanding
hereunder and if a proposed supplemental indenture shall directly affect the
rights of the Holders of Securities of one or more, but less than all, of such
series, then the consent only of the Holders of a majority in aggregate
principal amount of the Outstanding Securities of all series so directly
affected, considered as one class, shall be required; and provided, further,
that if the Securities of any series shall have been issued in more than one
Tranche and if the proposed supplemental indenture shall directly affect the

             thereof or the rate of interest thereon (or the amount of any
             installment of interest thereon) or change the method of
             calculating such rate or reduce any premium payable upon the
             redemption thereof, or reduce the amount of the principal of a
             Discount Security that would be due and payable upon a declaration
             of acceleration of the Maturity thereof pursuant to Section 802,

             Security or any premium or the interest thereon is payable, or
             impair the right to institute suit for the enforcement of any such
             payment on or after the Stated Maturity of any Security (or, in

                   (b) reduce the percentage in principal amount of the
             Outstanding Securities of any series or any Tranche thereof, the
             consent of the Holders of which is required for any such
             supplemental indenture, or the consent of the Holders of which is
             required for any waiver of compliance with any provision of this
             Indenture or of any default hereunder and its consequences, or
             reduce the requirements of Section 1304 for quorum or voting,

             Outstanding Security of such series or Tranche, or

                   (c) modify any of the provisions of this Section, Section
             607 or Section 813 with respect to the Securities of any series,
             or any Tranche thereof, or except to increase the percentages in
             principal amount referred to in this Section or such other
             Sections or to provide that other provisions of this Indenture
             cannot be modified or waived without the consent of the Holder of
             each Outstanding Security affected thereby; provided, however,
             that this clause shall not be deemed to require the consent of any
             Holder with respect to changes in the references to "the Trustee"
             and concomitant changes in this Section, or the deletion of this
             proviso, in accordance with the requirements of Sections 911(b)
             and 1201(h).

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 of one or more
Tranches thereof, or which modifies the rights of the Holders of Securities of
such series or Tranches 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 or Tranche.

             It shall not be necessary for any Act of Holders under this
Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof.  A
waiver by a Holder of such Holder's right to consent under this Section shall
be deemed to be a consent of such Holder.

SECTION 1203.      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 901) 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, immunities or liabilities under this Indenture or
otherwise.

SECTION 1204.      EFFECT OF SUPPLEMENTAL INDENTURES.

             Upon the execution of any supplemental indenture under this
Article this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes;
and every Holder of Securities theretofore or thereafter authenticated and
delivered hereunder shall be bound thereby.  Any supplemental indenture
permitted by this Article may restate this Indenture in its entirety, and, upon
the execution and delivery thereof, any such restatement shall supersede this
Indenture as theretofore in effect for all purposes.

             Securities of any series, or any Tranche thereof, 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, or
any Tranche thereof, 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 or Tranche.

SECTION 1207.      MODIFICATION WITHOUT SUPPLEMENTAL INDENTURE.

             If the terms of any particular series of Securities shall have
been established in a Board Resolution or an Officer's Certificate pursuant to
a Board Resolution as contemplated by Section 301, and not in an indenture
supplemental hereto, additions to, changes in or the elimination of any of such
terms may be effected by means of a supplemental Board Resolution or Officer's
Certificate, as the case may be, delivered to, and accepted by, the Trustee;
provided, however, that such supplemental Board Resolution or Officer's
Certificate shall not be accepted by the Trustee or otherwise be effective
unless all conditions set forth in this Indenture which would be required to be
satisfied if such additions, changes or elimination were contained in a
supplemental indenture shall have been appropriately satisfied.  Upon the
acceptance thereof by the Trustee, any such supplemental Board Resolution or
Officer's Certificate shall be deemed to be a "supplemental indenture" for
purposes of Section 1204 and 1206.

             series, or any Tranche or Tranches thereof, by the Company or by

             specified in Section 1301, by written request setting forth in
             reasonable detail the action proposed to be taken at the meeting,

             thereafter proceed to cause the meeting to be held as provided

amount of the Outstanding Securities of the series and Tranches with respect to
which a meeting shall have been called as hereinbefore provided, considered as
one class, shall constitute a quorum for a meeting of Holders of Securities of

at such meeting which this Indenture expressly provides may be taken by the
Holders of a specified percentage, which is less than a majority, in principal
amount of the Outstanding Securities of such series and Tranches, considered as
one class, the Persons entitled to vote such specified percentage in principal

                                      -58-
<PAGE>   69

as provided by Section 1305(e), notice of the reconvening of any meeting
adjourned for more than 30 days shall be given as provided in Section 1302(a)
not less than ten days prior to the date on which the meeting is scheduled to be

expressly the percentage, as provided above, of the principal amount of the
Outstanding Securities of such series and Tranches which shall constitute a

             Except as limited by Section 1202, any resolution presented to a
meeting or adjourned meeting duly reconvened at which a quorum is present as
aforesaid may be adopted only by the affirmative vote of the Holders of a
majority in aggregate principal amount of the Outstanding Securities of the
series and Tranches with respect to which such meeting shall have been called,
considered as one class; provided, however, that, except as so limited, any
resolution with respect to any action which this Indenture expressly provides
may be taken by the Holders of a specified percentage, which is less than a
majority, in principal amount of the Outstanding Securities of such series and
Tranches, considered as one class, may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of such specified percentage in principal
amount of the Outstanding Securities of such series and Tranches, considered as
one class.

             Any resolution passed or decision taken at any meeting of Holders
of Securities duly held in accordance with this Section shall be binding on all
the Holders of Securities of the series and Tranches with respect to which such
meeting shall have been held, whether or not present or represented at the
meeting.

SECTION 1305.      ATTENDANCE AT MEETINGS; DETERMINATION OF VOTING RIGHTS;
                   CONDUCT AND ADJOURNMENT OF MEETINGS.

                   (a) Attendance at meetings of Holders of Securities may be
             in person or by proxy; and, to the extent permitted by law, any
             such proxy shall remain in effect and be binding upon any future
             Holder of the Securities with respect to which it was given unless
             and until specifically revoked by the Holder or future Holder of
             such Securities before being voted.

                   (b) 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 in regard to
             proof of the holding of such Securities and of the appointment of
             proxies and in regard to the appointment and duties of inspectors
             of votes, the submission and examination of proxies, certificates
             and other evidence of the right to vote, and such other matters
             concerning the conduct of the meeting as it shall 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.  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.

                   (c) 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 as provided in Section
             1302(b), in which case the Company or the Holders of Securities of
             the series and Tranches 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 aggregate
             principal amount





                                      -59-

             of the Outstanding Securities of all series and Tranches
             represented at the meeting, considered as one class.

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

                   (e) Any meeting duly called pursuant to Section 1302 at
             which a quorum is present may be adjourned from time to time by
             Persons entitled to vote a majority in aggregate principal amount
             of the Outstanding Securities of all series and Tranches
             represented at the meeting, considered as one class; and the
             meeting may be held as so adjourned without further notice.

SECTION 1306.      COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

             The vote upon any resolution submitted to any meeting of Holders
shall be by written ballots on which shall be subscribed the signatures of the
Holders or of their representatives by proxy and the principal amounts and
serial numbers of the Outstanding Securities, of the series and Tranches with
respect to which the meeting shall have been called, 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 of all votes cast at the meeting.  A record of the
proceedings of each meeting of Holders 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 1302 and, if applicable, Section 1304.  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.

SECTION 1307.      ACTION WITHOUT MEETING.

             In lieu of a vote of Holders at a meeting as hereinbefore
contemplated in this Article, any request, demand, authorization, direction,
notice, consent, waiver or other action may be made, given or taken by Holders
by written instruments as provided in Section 104.

past, present or future, of the Company or of any predecessor or successor
corporation, either directly or indirectly through the Company or any
predecessor or successor corporation, because of the indebtedness hereby
authorized or under or by reason of any of the obligations, covenants or
agreements contained in this Indenture or in any of the Securities or to be
implied herefrom or therefrom, and that any such personal liability is hereby
expressly waived and released as a condition of, and as part of the
consideration for, the execution of this Indenture and the issuance of the
Securities.


                                ARTICLE FIFTEEN

                          SUBORDINATION OF SECURITIES


SECTION 1501.      SECURITIES SUBORDINATE TO SENIOR INDEBTEDNESS.

             The Company, for itself, its successors and assigns, covenants and
agrees, and each Holder of the Securities of each series, by its acceptance
thereof, likewise covenants and agrees, that the payment of the principal of
and premium, if any, and interest, if any, on each and all of the Securities is
hereby expressly subordinated, to the extent and in the manner set forth in
this Article, in right of payment to the prior payment in full of all Senior
Indebtedness.

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

SECTION 1502.      PAYMENT OVER OF PROCEEDS OF SECURITIES.

             In the event (a) of any insolvency or bankruptcy proceedings or
any receivership, liquidation, reorganization or other similar proceedings in
respect of the Company or a substantial part of its property, or of any
proceedings for liquidation, dissolution or other winding up of the Company,
whether or not involving insolvency or bankruptcy, or (b) subject to the
provisions of Section 1503, that a default shall have occurred with respect to
the payment of principal of or interest on or other monetary amounts due and
payable on any Senior Indebtedness, and such default shall have continued
beyond the period of grace, if any, in respect thereof and shall not have been
cured or waived or shall not have ceased to exist, or (c) that the principal of
and accrued interest on the Securities of any series shall have been declared
due and payable pursuant to Section 801 and such declaration shall not have
been rescinded and annulled as provided in Section 802, then:

                   (1) the holders of all Senior Indebtedness shall first be
             entitled to receive payment of the full amount due thereon, or
             provision shall be made for such payment in money or money's
             worth, before the Holders of any of the Securities are entitled to
             receive a payment 



                                      -61-
<PAGE>   72

             on account of the principal of or interest on the indebtedness
             evidenced by the Securities, including, without limitation, any
             payments made pursuant to Articles Four and Five;

                   (2) any payment by, or distribution of assets of, the
             Company of any kind or character, whether in cash, property or
             securities, to which any Holder or the Trustee would be entitled
             except for the provisions of this Article, shall be paid or
             delivered by the Person making such payment or distribution,
             whether a trustee in bankruptcy, a receiver or liquidating trustee
             or otherwise, directly to the holders of such Senior Indebtedness
             or their representative or representatives or to the trustee or
             trustees under any indenture under which any instruments
             evidencing any of such Senior Indebtedness may have been issued,
             ratably according to the aggregate amounts remaining unpaid on
             account of such Senior Indebtedness held or represented by each,
             to the extent necessary to make payment in full of all Senior
             Indebtedness remaining unpaid after giving effect to any
             concurrent payment or distribution (or provision therefor) to the
             holders of such Senior Indebtedness, before any payment or
             distribution is made to the Holders of the indebtedness evidenced
             by the Securities or to the Trustee under this Indenture; and

                   (3) in the event that, notwithstanding the foregoing, any
             payment by, or distribution of assets of, the Company of any kind
             or character, whether in cash, property or securities, in respect
             of principal of or interest on the Securities or in connection
             with any repurchase by the Company of the Securities, shall be
             received by the Trustee or any Holder before all Senior
             Indebtedness is paid in full, or provision is made for such
             payment in money or money's worth, such payment or distribution in
             respect of principal of or interest on the Securities or in
             connection with any repurchase by the Company of the Securities
             shall be paid over to the holders of such Senior Indebtedness or
             their representative or representatives or to the trustee or
             trustees under any indenture under which any instruments
             evidencing any such Senior Indebtedness may have been issued,
             ratably as aforesaid, for application to the payment of all Senior
             Indebtedness remaining unpaid until all such Senior Indebtedness
             shall have been paid in full, after giving effect to any
             concurrent payment or distribution (or provision therefor) to the
             holders of such Senior Indebtedness.

             Notwithstanding the foregoing, at any time after the 123rd day
following the date of deposit of cash or Eligible Obligations pursuant to
Section 701 (provided all conditions set out in such Section shall have been
satisfied), the funds so deposited and any interest thereon will not be subject
to any rights of holders of Senior Indebtedness including, without limitation,
those arising under this Article Fifteen; provided that no event described in
clauses (d) and (e) of Section 801 with respect to the Company has occurred
during such 123-day period.

             For purposes of this Article only, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan or reorganization or readjustment which are
subordinate in right of payment to all Senior Indebtedness which may at the
time be outstanding to the same extent as, or to a greater extent than, the
Securities are so subordinated as provided in this Article.  The consolidation
of the Company with, or the merger of the Company into, another corporation or
the liquidation or dissolution of the Company following the conveyance or
transfer of its property as an entirety, or substantially as an entirety, to
another corporation upon the terms and conditions provided for in Article
Eleven hereof shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section 1502 if such other corporation
shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions stated in Article Eleven hereof.  Nothing in 



                                      -62-

Section 1501 or in this Section 1502 shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 907.

SECTION 1503.      DISPUTES WITH HOLDERS OF CERTAIN SENIOR INDEBTEDNESS.

             Any failure by the Company to make any payment on or perform any
other obligation in respect of Senior Indebtedness, other than any indebtedness
incurred by the Company or assumed or guaranteed, directly or indirectly, by
the Company for money borrowed (or any deferral, renewal, extension or
refunding thereof) or any other obligation as to which the provisions of this
Section shall have been waived by the Company in the instrument or instruments
by which the Company incurred, assumed, guaranteed or otherwise created such
indebtedness or obligation, shall not be deemed a default under clause (b) of
Section 1502 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 that 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 or execution shall have been obtained pending such appeal or
review.

SECTION 1504.      SUBROGATION.

             Senior Indebtedness shall not be deemed to have been paid in full
unless the holders thereof shall have received cash (or securities or other
property satisfactory to such holders) in full payment of such Senior
Indebtedness then outstanding.  Upon the payment in full of all Senior
Indebtedness, the Holders of the Securities shall be subrogated to the rights
of the holders of Senior Indebtedness to receive any further payments or
distributions of cash, property or securities of the Company applicable to the
holders of the Senior Indebtedness until all amounts owing on the Securities
shall be paid in full; and such payments or distributions of cash, property or
securities received by the Holders of the Securities, by reason of such
subrogation, which otherwise would be paid or distributed to the holders of
such Senior Indebtedness shall, as between the Company, its creditors other
than the holders of Senior Indebtedness, and the Holders, be deemed to be a
payment by the Company to or on account of Senior Indebtedness, it being
understood that the provisions of this Article are and are intended solely for
the purpose of defining the relative rights of the Holders, on the one hand,
and the holders of the Senior Indebtedness, on the other hand.

SECTION 1505.      OBLIGATION OF THE COMPANY UNCONDITIONAL.

             Nothing contained in this Article or elsewhere in this Indenture
or in the Securities is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Indebtedness and the Holders, the
obligation of the Company, which is absolute and unconditional, to pay to the
Holders the principal of and interest on the Securities as and when the same
shall become due and payable in accordance with their terms, or is intended to
or shall affect the relative rights of the Holders and creditors of the Company
other than the holders of Senior Indebtedness, nor shall anything herein or
therein prevent the Trustee or any Holder from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture,
subject to the rights, if any, under this Article of the holders of Senior
Indebtedness in respect of cash, property or securities of the Company received
upon the exercise of any such remedy.

             Upon any payment or distribution of assets or securities of the
Company referred to in this Article, the Trustee and the Holders shall be
entitled to rely upon any order or decree of a court of competent jurisdiction
in which such dissolution, winding up, liquidation or reorganization
proceedings are pending 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.

SECTION 1506.      PRIORITY OF SENIOR INDEBTEDNESS UPON MATURITY.

             Upon the maturity of the principal of any Senior Indebtedness by
lapse of time, acceleration or otherwise, all matured principal of Senior
Indebtedness and interest and premium, if any, thereon shall first be paid in
full before any payment of principal or premium or interest, if any, is made
upon the Securities or before any Securities can be acquired by the Company or
any sinking fund payment is made with respect to the Securities (except that
required sinking fund payments may be reduced by Securities acquired before
such maturity of such Senior Indebtedness).

SECTION 1507.      TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS.

             The Trustee shall be entitled to all rights set forth in this
Article with respect to any Senior Indebtedness at any time held by it, to the
same extent as any other holder of Senior Indebtedness.  Nothing in this
Article shall deprive the Trustee of any of its rights as such holder.

SECTION 1508.      NOTICE TO TRUSTEE TO EFFECTUATE SUBORDINATION.

             Notwithstanding the provisions of this Article or any other
provision of the Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts which would prohibit the making of any payment of
moneys to or by the Trustee unless and until the Trustee shall have received
written notice thereof from the Company, from a Holder or from a holder of any
Senior Indebtedness or from any representative or representatives of such
holder and, prior to the receipt of any such written notice, the Trustee shall
be entitled, subject to Section 901, in all respects to assume that no such
facts exist; provided, however, that, if prior to the fifth Business Day
preceding the date upon which by the terms hereof any such moneys may become
payable for any purpose, or in the event of the execution of an instrument
pursuant to Section 702 acknowledging satisfaction and discharge of this
Indenture, then if prior to the second Business Day preceding the date of such
execution, the Trustee shall not have received with respect to such moneys the
notice provided for in this Section, then, anything herein contained to the
contrary notwithstanding, the Trustee may, in its discretion, receive such
moneys and/or 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 on or after such date; provided, however, that no such application shall
affect the obligations under this Article of the persons receiving such moneys
from the Trustee.

SECTION 1509.      MODIFICATION, EXTENSION, ETC., OF SENIOR INDEBTEDNESS.

             The holders of Senior Indebtedness may, without affecting in any
manner the subordination of the payment of the principal of and premium, if
any, and interest, if any, on the Securities, at any time or from time to time
and in their absolute discretion, agree with the Company to change the manner,
place or terms of payment, change or extend the time of payment of, or renew or
alter, any Senior Indebtedness, or amend or supplement any instrument pursuant
to which any Senior Indebtedness is 



                                      -64-
<PAGE>   75

issued, 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 or the Trustee.

SECTION 1510.      TRUSTEE HAS NO FIDUCIARY DUTY TO HOLDERS OF SENIOR
                   INDEBTEDNESS.

             With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and objectives
as are specifically set forth in this Indenture, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee.  The Trustee shall not be deemed to
owe any fiduciary duty to the holders of Senior Indebtedness, and shall not be
liable to any such holders if it shall mistakenly pay over or deliver to the
Holders or the Company or any other Person, money or assets to which any
holders of Senior Indebtedness shall be entitled by virtue of this Article or
otherwise.

SECTION 1511.      PAYING AGENTS OTHER THAN THE TRUSTEE.

             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 shall in such case (unless the context shall
otherwise require) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying
Agent were named in this Article in addition to or in place of the Trustee;
provided, however, that Sections 1507, 1508 and 1510 shall not apply to the
Company if it acts as Paying Agent.

SECTION 1512.      RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS NOT IMPAIRED.

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

SECTION 1513.      EFFECT OF SUBORDINATION PROVISIONS; TERMINATION.

             Notwithstanding anything contained herein to the contrary, other
than as provided in the immediately succeeding sentence, all the provisions of
this Indenture shall be subject to the provisions of this Article, so far as
the same may be applicable thereto.

             Notwithstanding anything contained herein to the contrary, the
provisions of this Article Fifteen shall be of no further effect, and the
Securities shall no longer be subordinated in right of payment to the prior
payment of Senior Indebtedness, if the Company shall have delivered to the
Trustee a notice to such effect.  Any such notice delivered by the Company
shall not be deemed to be a supplemental indenture for purposes of Article
Twelve hereof.

                          ___________________________

             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.

                     RESOLVED, that the transaction negotiated with Lehman
              Brothers Inc. for the purchase from Union Electric Company (the
              "Company") of $65,500,000 aggregate principal amount of the
              Company's SKIS (as defined herein), to be issued pursuant to an
              Indenture (For Unsecured Subordinated Debt Securities) dated as
              of December 1, 1996 (the "Subordinated Indenture") from the
              Company to Boatmen's Trust Company, as trustee (the "Subordinated
              Indenture Trustee"), which transaction provides for an interest
              rate to be borne by the securities of 7.69%, is hereby approved
              and accepted and the execution and delivery of the Subordinated
              Indenture be and hereby is approved, ratified and confirmed; that
              the execution and delivery of the Underwriting Agreement dated
              December 10, 1996 by the officers of the Company, providing for a
              consideration of $64,845,000 to be paid to the Company for the
              SKIS, be and hereby is approved, ratified and confirmed; and such
              officers be and hereby are authorized to take all such further
              actions as they may deem necessary or desirable in order to carry
              into effect the terms and provisions of such Subordinated
              Indenture and Underwriting Agreement.

                     RESOLVED, that:

                     (i) the securities to be issued under the Subordinated
                     Indenture shall be designated "7.69% Subordinated Capital
                     Income Securities (Series A Subordinated Deferrable
                     Interest Debentures)" (the "SKIS"); all capitalized terms
                     used in these resolutions and not defined herein shall
                     have the meaning set forth in the Subordinated Indenture;

                     (ii) the SKIS shall be limited in aggregate principal
                     amount to $65,500,000 at any time Outstanding;

                     (iii) the SKIS shall mature and the principal thereof
                     shall be due and payable on December 15, 2036, together
                     with all accrued and unpaid interest thereon to, but not
                     including, such date;

                     (iv) the SKIS shall bear interest from the date of
                     original issuance (which is anticipated to be December 16,
                     1996) at the rate of 7.69% per annum payable semi-annually
                     in arrears on June 15 and December 15 of each year (each,
                     an "Interest Payment Date") commencing June 15, 1997. The
                     amount of interest payable for any such period will be
                     computed on the basis of a 360-day year of twelve 30-day
                     months.  Interest on the SKIS will accrue from the date of
                     original issuance but if interest has been paid on such
                     SKIS, then from the most recent Interest Payment Date
                     through which interest has been paid.  In the event that
                     any Interest Payment Date is not a Business Day, then
                     payment of interest payable on such date will be made on
                     the next succeeding date which is a Business Day (and
                     without any interest or other payment in respect of such
                     delay), with the same force and effect as if made on such
                     Interest Payment Date;

                     (v) each installment of interest on the SKIS shall be
                     payable to the Person in whose name such SKIS are
                     registered at the close of business on the Business Day
                     next preceding the corresponding Interest Payment Date
                     (the "Regular Record Date") for the SKIS. Any installment
                     of interest on the SKIS not punctually paid or duly
                     provided for shall forthwith cease to be payable to the
                     Holders on such Regular Record Date, and may be paid to
                     the
<PAGE>   2
                                      -2-

                     person in whose name the SKIS is registered at the close of
                     business on a Special Record Date to be fixed by the
                     Subordinated Indenture Trustee for the payment of such
                     defaulted interest, notice whereof shall be given to the
                     Holders of the SKIS not less than 10 days prior to such
                     Special Record Date, or may be paid at any time in any
                     other lawful manner not inconsistent with the requirements
                     of any securities exchange on which the SKIS may be listed,
                     and upon such notice as may be required by such exchange,
                     all as more fully provided in the Subordinated Indenture;

                     (vi) the principal and each installment of interest on the
                     SKIS shall be payable at the office or agency of the
                     Company in St. Louis, Missouri.  For so long as the SKIS
                     are registered in the name of The Depository Trust Company
                     ("DTC") or its nominee, the principal and the interest due
                     on the SKIS will be payable by the Company or its agent to
                     DTC for payment to its participants for subsequent
                     disbursement to beneficial owners. The Company will
                     initially be the Paying Agent and the Registrar for the
                     SKIS;

                     (vii) the SKIS will not be redeemable prior to December
                     15, 2006; thereafter, the SKIS will be redeemable at the
                     option of the Company, in whole or in part, at any time on
                     or after December 15, 2006 at the following redemption
                     prices (in each case expressed in percentages of principal
                     amount):

                     in each case, upon not less than 30 nor more than 60 days'
                     notice, together with accrued interest to, but not
                     including, the date fixed for redemption;

                     (viii) so long as any SKIS are Outstanding, the failure of
                     the Company to pay interest on any SKIS within 60 days
                     after the same becomes due and payable (whether or not
                     payment is prohibited by the provisions of Article Fifteen
                     of the Subordinated Indenture) shall constitute an Event
                     of Default; provided, however, that a valid extension of
                     the interest payment period by the Company as contemplated
                     in Section 312 of the Subordinated Indenture and paragraph
                     (ix) of these Board Resolutions shall not constitute a
                     failure to pay interest for this purpose;

                                      -3-

                     (ix) pursuant to Section 312 of the Subordinated
                     Indenture, the Company shall have the right, at any time
                     and from time to time during the term of the SKIS, to
                     extend the interest payment period to a period not
                     exceeding 10 consecutive semi- annual periods (an
                     "Extended Interest Payment Period"), and at the end of
                     such Extended Interest Payment Period, the Company shall
                     pay all interest accrued and unpaid (together with
                     interest thereon at the same rate as specified for the
                     SKIS to the extent permitted by applicable law) through
                     the last day of such Extended Interest Payment Period
                     provided that if any principal amount of the SKIS is paid
                     on such day, then not including interest for such day with
                     respect to such amount; provided, however, that during
                     such Extended Interest Payment Period, the Company shall
                     not declare or pay any dividend on, or redeem, purchase,
                     acquire or make a liquidation payment with respect to, any
                     of its capital stock or make any guarantee payments with
                     respect to the foregoing.  Prior to the termination of any
                     such Extended Interest Payment Period, the Company may
                     further extend the interest payment period, provided that
                     such Extended Interest Payment Period together with all
                     such previous and further extensions thereof may not
                     exceed 10 consecutive semi-annual periods or extend beyond
                     the Stated Maturity of the SKIS. Upon the termination of
                     any Extended Interest Payment Period and the payment of
                     all amounts then due, the Company may select a new
                     Extended Interest Payment Period, subject to the above
                     requirements.  No interest during an Extended Interest
                     Payment Period, except at the end thereof, shall be due
                     and payable;

                     (x) the Company shall give the Holders of the SKIS and the
                     Subordinated Indenture Trustee written notice of its
                     selection of such Extended Interest Payment Period ten
                     (10) Business Days prior to the earlier of (i) the next
                     succeeding Interest Payment Date and (ii) the date the
                     Company is required to give notice to Holders of the SKIS
                     (or, if applicable, to the New York Stock Exchange or
                     other applicable self-regulatory organization) of the
                     record or payment date of such interest payment, but in
                     any event not less than two Business Days prior to such
                     record date. The semi-annual period in which any notice is
                     given pursuant to this paragraph shall constitute one of
                     the 10 semi-annual periods which comprise the maximum
                     Extended Interest Payment Period;

                     (xi) the SKIS will be originally issued in global form
                     payable to Cede & Co., and will, unless and until the SKIS
                     are exchanged in whole or in part for certificated SKIS
                     registered in the names of the various beneficial holders
                     thereof, contain restrictions on transfer, substantially
                     as described in the form of SKIS; and

                     (xii) the SKIS shall have such other terms and provisions
                     as are provided in the form of subordinated debt security
                     attached hereto and made a part hereof, and shall be
                     issued in such form.

(herein called the Trustee, which term includes any successor trustee under the
Indenture), and reference is hereby made to the Indenture, including the Board
Resolutions filed with the Trustee on December 11, 1996 creating the series
designated on the face hereof, for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the

together in the case of any such redemption with accrued interest to, but not

is on or prior to such Redemption Date will be payable to the Holder of such
Security, or one or more Predecessor Securities, of record at the close of
business on the related Regular Record Date referred to on the face hereof, all
as provided in the Indenture.

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

     The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinated and subject in right of payment to the prior
payment in full of all Senior Indebtedness, and this Security is issued subject
to the provisions of the Indenture with respect thereto. Each Holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his or her behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the
subordination so provided and (c) appoints the Trustee his or her
attorney-in-fact for any and all such purposes. Each Holder hereof, by his or
her acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder
of Senior Indebtedness, whether now outstanding or hereafter incurred, and
waives reliance by each such Holder upon said provisions.

     The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Security upon compliance with certain conditions set forth
in the Indenture.

     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

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

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

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Security at the times, place and rate, and in the coin or currency, herein
prescribed.

     The Company shall have the right at any time and from time to time during
the term of the Securities of this series to extend the interest payment period
to a period not exceeding 10 consecutive semi-annual periods (an "Extended
Interest Payment Period"), and at the end of such Extended Interest Payment
Period, the Company shall pay all interest then accrued and unpaid (together
with interest thereon at the same rate as specified for the Securities of this
series to the extent permitted by applicable law) through the last day of such
Extended Interest Payment Period provided that if any principal amount of this
Security is paid on such day, then not including interest for such day with
respect to such principal amount; provided, however, that during such Extended
Interest Payment Period the Company shall not declare or pay any dividend on,
or redeem, purchase, acquire or make a liquidation payment with respect to, any
of its capital stock or make any guarantee payments with respect to the
foregoing. Prior to the termination of any such Extended Interest Payment
Period, the Company may further extend the interest payment period, provided
that such Extended Interest Payment Period, together with all such previous and
further extensions thereof, may not exceed 10 consecutive semi-annual periods
or extend beyond the Stated Maturity of the Securities of this series. Upon the
termination of any such Extended Interest Payment Period and the payment of all
amounts then due, the Company may select a new Extended Interest Payment
Period, subject to the above requirements. No interest during an Extended
Interest Payment Period, except at the end thereof, shall be due and payable.
The Company shall give the Holder of this Security notice of its selection of
such Extended Interest Payment Period as provided in the Indenture.

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

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

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

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

                                     LEGEND

     Unless and until this Security is exchanged in whole or in part for
certificated Securities registered in the names of the various beneficial
holders hereof as then certified to the Trustee by The Depository Trust Company
or its successor (the "Depositary"), this Security may not be transferred
except as a whole by the Depositary to a nominee of the Depositary or by a
nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary.

     Unless this certificate is presented by an authorized representative of
the Depositary to the Company or its agent for registration of transfer,
exchange or payment, and any certificates to be issued is registered in the
name of Cede & Co., or such other name as requested by an authorized
representative of the Depositary and any amount payable thereunder is made
payable to Cede & Co., or such other name, ANY TRANSFER, PLEDGE OR OTHER USE
HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL since the
registered owner hereof, Cede & Co., has an interest herein.

     This Security may be exchanged for certificated Securities registered in
the names of the various beneficial owners hereof if (a) the Depositary is at
any time unwilling or unable to continue as depositary and a successor
depositary is not appointed by the Company within 90 days, or (b) the Company
elects to issue certificated Securities to beneficial owners (as certified to
the Company by the Depositary).

and 1995, and the results of its operations and its cash flows for each of the
three years in the period ended December 31, 1996, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

MANAGEMENT'S DISCUSSION AND ANALYSIS


Union Electric is an investor-owned regulated public utility that supplies
electric and gas services to 1.3 million customers in a 24,500 square-mile area
in Missouri (including metropolitan St. Louis) and Illinois.

MERGER

Union Electric and CIPSCO Incorporated (CIPSCO) entered into a Merger Agreement
(Agreement) dated August 11, 1995. The Agreement was approved by the
shareholders of both companies in December 1995. The merged entity is expected
to realize $644 million in net savings over 10 years from combining certain
operations of the two companies and is expected to adopt Union Electric's
dividend payment level. However, the merger is conditioned upon, among other
things, receipt of certain regulatory and governmental approvals. At this time,
the merger is expected to be consummated by the end of 1997. See Note 2 -
Merger Agreement under Notes to Financial Statements for further information.

RESULTS OF OPERATIONS

Common stock earnings for 1996, 1995 and 1994 were $292 million ($2.86 per
share), $301 million ($2.95 per share) and $308 million ($3.01 per share),
respectively. Earnings and earnings per share fluctuated due to many
conditions, primarily: weather variations, electric rate reductions, credits to
electric customers, sales growth, fluctuating operating costs, including
Callaway nuclear refueling outages, merger-related expenses, changes in
interest expense and changes in income and property taxes.
     The impacts of the more significant items affecting revenues, costs and
earnings during the past several years are analyzed and discussed below:

===================================================================
</TABLE>

     The increase in 1996 electric revenues was due to a 3.5% increase in
kilowatthour sales over the year-ago period, partly offset by the 1.8% rate
decrease for Missouri electric customers and the net increase in customer
credits recorded during 1996 versus 1995. See Note 3 - Regulatory Matters under
Notes to Financial Statements for further information. The kilowatthour sales
increase reflected strong economic growth in Union Electric's service area and
increased interchange sales opportunities, partially offset by milder weather
during the period. Residential and commercial sales each rose 3% over 1995,
while industrial sales grew 2% and interchange sales increased 7%.
     The increase in 1995 electric revenues was due to increased retail
kilowatthour sales compared to 1994, mainly due to unusually hot weather in the
third quarter and sales growth reflecting our healthy service area economy.
Weather-sensitive residential and commercial sales increased 6% and 3%,
respectively, over 1994, and industrial sales grew 3%. This increase was
partially offset by the one-time $30 million credit, the rate decrease and a 17%
decline in interchange sales due to decreased interchange sales opportunities.
See Note 3 - Regulatory Matters under Notes to Financial Statements for further
information.
     The increase in 1994 electric revenues reflected growth in sales to
commercial and industrial customers of 4% and 2%, respectively, and increased
interchange sales of 9%, partially offset by reduced sales to residential
customers of 2%, primarily due to milder weather in the first and third quarters
of 1994, compared to 1993.

===========================================================================
</TABLE>

     The increase in 1996 fuel and purchased power costs was driven mainly by
higher kilowatthour sales, partially offset by lower fuel prices due to the use
of lower-cost coal. The


                                       17


<PAGE>   3

MANAGEMENT'S DISCUSSION AND ANALYSIS


increase in 1995 fuel and purchased power costs reflected increased purchased
power costs due to greater kilowatthour sales during the hot 1995 summer and the
need for replacement power during Callaway's spring refueling outage. The
decrease in 1994 fuel and purchased power costs reflected lower fuel prices,
resulting from the increased use of low-sulfur coal at our fossil plants and
greater generation at our nuclear plant due to the absence of a refueling outage
in 1994. Higher generation, resulting in greater fuel costs, was offset in part
by reduced purchased power costs.
     Other operating expense variations in 1994 through 1996 reflected
recurring factors such as growth, inflation, and wage and benefit increases. In
1996, operations expenses, other than fuel and purchased power costs, increased
$25 million primarily due to a 26% rise in natural gas purchased for resale
(due to higher sales and gas prices), and increased employee benefits, injuries
and damages, and consulting expenses. In 1995, operations expenses, other than
fuel and purchased power costs, decreased $17 million, mainly due to a 15%
reduction in natural gas purchased for resale (due primarily to lower gas
prices) and decreases in employee benefits, injuries and damages, and insurance
expenses. These decreases were partially offset by increased labor and material
and supplies expenses. In 1994, operations expenses, other than fuel and
purchased power costs, decreased $10 million, primarily due to a 10% reduction
in natural gas purchased for resale (due to lower sales and gas prices), and
decreases in labor and employee benefits expenses. These decreases were
partially offset by increased injuries and damages, consulting and
communications expenses.
     In 1996, maintenance expenses increased $2 million primarily due to
increased labor expenses at Callaway and the fossil plants. In 1995,
maintenance expenses increased $24 million, mainly due to increased power plant
maintenance expenses partially offset by reduced distribution system
maintenance expenses. Callaway Plant's maintenance expenses increased $17
million primarily due to the spring 1995 nuclear refueling outage. Maintenance
expenses at other power plants increased $11 million primarily due to scheduled
maintenance outages. In 1994, maintenance expenses increased $8 million, mainly
caused by additional maintenance expenses at the fossil plants and greater
tree-trimming expenses, partly offset by lower Callaway Plant maintenance
expenses (no refueling outage in 1994) and reduced labor expenses.
     Depreciation expense increased $8 million in 1996, $7 million in 1995, and
$6 million in 1994, due to increased depreciable property.

TAXES
Income tax expense from operations decreased $12 million in 1996 principally
due to lower pre-tax income and a lower effective income tax rate. Income tax
expense from operations increased $3 million in 1995 primarily due to a higher
effective income tax rate partially offset by lower pre-tax income. The $27
million increase in 1994 income tax expense resulted from higher pre-tax income
and a higher effective Missouri income tax rate.
     In 1996, other taxes charged to operating expenses increased $1 million due
to increased real estate and payroll taxes. In 1995, other taxes charged to
operating expenses increased $2 million due to increased gross receipts taxes
from greater electric revenues and increased real estate taxes. In 1994, other
taxes charged to operating expenses rose $4 million due to increased real estate
taxes and greater corporate franchise taxes.


OTHER INCOME AND DEDUCTIONS
Miscellaneous, net increased $1 million for 1996, primarily due to reduced
merger-related expenses. Miscellaneous, net decreased $6 million for 1995,
primarily due to merger-related expenses. Merger-related expenses totaled $8
million and $9 million in 1996 and 1995, respectively. See Note 2 - Merger
Agreement, under Notes to Financial Statements for further information.
Miscellaneous, net decreased $4 million for 1994, primarily due to increased
charitable contributions.


INTEREST
Interest expense for 1996 decreased $2 million primarily due to lower debt
outstanding during the year and lower rates on variable-rate long-term debt. In
1995, interest expense declined $6 million as decreases in other interest
expense were partly offset by higher interest rates on variable-rate long-term
debt. In 1994, interest expense

                                                      UE 1996 ANNUAL REPORT


increased $12 million generally due to a greater amount of total debt
outstanding and overall higher interest rates on variable-rate debt.


BALANCE SHEET
The $55 million increase in other current and accrued liabilities at December
31, 1996, compared to December 31, 1995, was primarily due to the timing of the
payments of the $47 million customer credit. See Note 3 - Regulatory Matters,
under Notes to Financial Statements for further information.


LIQUIDITY AND CAPITAL RESOURCES
Cash provided by operating activities totaled $605 million for 1996, compared
to $640 million and $544 million for 1995 and 1994, respectively.
     Cash flows used in investing activities totaled $363 million, $341 million
and $333 million for the years ended December 31, 1996, 1995 and 1994,
respectively. Expenditures in 1996 for constructing new or improving existing
facilities, purchasing rail cars and complying with the Clean Air Act were $325
million. In addition, the Company spent $51 million to acquire nuclear fuel.
     The Company completed Callaway Plant construction in late 1984. The need
for additional base load electric generating capacity is not anticipated until
after the year 2013. Under the Clean Air Act Amendments of 1990, the Company is
required to reduce total annual sulfur dioxide emissions significantly by the
year 2000. Significant reductions in nitrogen oxide are also required. By
switching to low-sulfur coal and early banking of emission credits, the Company
anticipates that it can comply with the requirements of the law without
significant revenue increases because the related capital costs, estimated at
about $300 million, are largely offset by lower fuel costs. As of year-end
1996, about 84% of the Clean Air Act-related capital costs have been expended.

     In December 1996, the Environmental Protection Agency proposed new air
quality standards for ozone and particulate matter. The proposed standards, if
ultimately adopted, would result in increased clean air related capital costs
and operating expenses. However, the Company is unable to predict whether any
new air quality standards will be adopted, or what impact any new standards
would have on the Company's future financial condition, results of operations
or liquidity.
     See Note 13 - Callaway Nuclear Plant under Notes to Financial Statements
for a discussion of Callaway Plant decommissioning costs.
     Cash flows used in financing activities were $238 million for 1996,
compared to $299 million and $211 million for 1995 and 1994, respectively. The
Company's principal financing activities during 1996 included the redemption of
$35 million of First Mortgage Bonds and $8 million of short-term debt bank
loans, and the payment of dividends. In addition, on December 16, 1996, Union
Electric issued $65.5 million of Subordinated Deferrable Interest Debentures,
7.69% Series, due 2036. The Company used the proceeds to redeem certain series
of preferred stock in January 1997.

short-term unsecured debt instruments outstanding at any one time. Short-term
borrowings consist of bank loans (maturities generally on an overnight basis)
and commercial paper (maturities generally within 10 to 45 days). At December
31, 1996, the Company had committed bank lines of credit aggregating $179
million (of which $168 million were unused at such date) which make available
interim financing at various rates of interest based on LIBOR, the bank
certificate of deposit rate, or other options. The lines of credit are
renewable annually at

various dates throughout the year. The Company also has bank credit agreements
due 1999 which permit the borrowing of up to $300 million and $200 million on a
long-term basis. At December 31, 1996, no such borrowings were outstanding.
     Additionally, the Company has a lease agreement which provides for the
financing of nuclear fuel. At December 31, 1996, the maximum amount which could
be financed under the agreement was $120 million. Cash provided from financing
for 1996 included issuances under the lease for nuclear fuel of $44 million
offset in part by $35 million of redemptions. At December 31, 1996 $106 million
was financed under the lease. See Note 6 - Nuclear Fuel Lease under Notes to
Financial Statements for further information.


CONTINGENCIES
See Note 12 - Contingencies under Notes to Financial Statements for material
issues existing at December 31, 1996.


DIVIDENDS
On October 11, 1996, the Board of Directors increased the quarterly common
stock dividend to 63.5 cents per share from 62.5 cents, raising the indicated
annualized common stock dividend to $2.54 per share. Common stock dividends
paid in 1996 resulted in a pay out rate of 88% of the Company's earnings to
common stockholders. Dividends paid to common stockholders in relation to net
cash provided by operating activities for the same period were 42%.
     The Board of Directors does not set specific targets or payout parameters
for dividend payments. In its annual review of dividend payments, however, the
Board considers various issues including the Company's historic earnings and
cash flow; projected earnings, cash flow and potential cash flow requirements;
dividend increases at other utilities; return on investments with similar risk
characteristics; and overall business considerations.


RATE MATTERS
See Note 3 - Regulatory Matters under Notes to Financial Statements for further
information.


INDUSTRY RESTRUCTURING
Changes enacted and being considered at the federal and state levels continue
to change the structure of the industry and utility regulation, as well as
encourage increased competition. At the federal level, the Energy Policy Act of
1992 reduced various restrictions on the operation and ownership of independent
power producers and gave the FERC the authority to order electric utilities to
provide transmission access to third parties.
     On April 24, 1996, the FERC issued Order 888 and Order 889 which are
intended to promote competition in the wholesale electric market. The FERC
requires transmission-owning public utilities, such as the Company, to provide
transmission access and service to others in a manner similar and comparable to
that which the utility has by virtue of ownership. Order 888 requires that a
single tariff be used by the utility in providing transmission service. Order
888 also provides for the recovery of stranded costs.
     Order 889 established the standards of conduct and information
requirements that transmission owners must adhere to in doing business under
the open access rule. Under Order 889, utilities must obtain transmission
service for their own use in the same manner their customers will obtain
service, thus mitigating market power through control of transmission
facilities. In addition, under Order 889, utilities must separate their
merchant function (buying and selling wholesale power) from their transmission
and reliability functions.
     The Company believes that Order 888 and Order 889, which relate to its
wholesale business, will not have a material adverse effect on its financial
condition, results of operations or liquidity.
     In addition, certain states are considering proposals that would
restructure the industry at the retail level. In Missouri, where 92% of the
Company's retail electric revenues are derived, there has been no significant
legislative action regarding industry restructuring to date, nor has retail
wheeling been allowed in the state. However, the joint stipulation agreement
submitted to the Missouri Public Service Commission in July 1996 as part of the
Company's proposed merger with CIPSCO includes a provision that would require
the Company to file a proposal for a 100-megawatt experimental retail wheeling
pilot program in Missouri. (See Note 3 - Regulatory Matters under Notes to
Financial Statements.)
     In Illinois, the state General Assembly formed the Joint Committee on
Electric Utility Reform (Joint Committee) in May 1995 to study utility
deregulation and issue a recom-

                                                           UE 1996 ANNUAL REPORT


mendation. The Joint Committee did not issue a final recommendation
during 1996. However, in November 1996, the Illinois Coalition for Responsible
Electricity Choice (Coalition ) proposed legislation to restructure the
Illinois electric industry. The Coalition is comprised of most of the state's
investor-owned utilities, including the Company, and various business and
consumer groups. The proposed legislation provides for an electric rate freeze
through 1999; an annual 1.5% residential electric rate reduction from 2000 to
2004; retail choice for customers (large utility users would have this option
in 2000, with all other customers being phased in through 2005); recovery of
transition costs; and retail wheeling pilot programs. Other forms of
legislation have been proposed as well.
     The Company is unable to predict the timing or ultimate outcome of the
various industry restructuring initiatives being considered. The potential
negative financial consequences of industry restructuring include the
impairment and writedown of certain assets, including regulatory assets, lower
revenues, reduced profit margins and increased costs of capital. At this time,
the Company is unable to predict the impact of potential industry restructuring
matters on the Company's future financial condition, results of operations or
liquidity.


OUR STRATEGY
The Company's management and Board of Directors recognize the increasing
probability of more competition in the future, and although the Company cannot
accurately predict the timing or nature of this competition, the Company
operates its business assuming this competition will occur. Union Electric's
basic business strategy is 1) to improve the Company's competitive position by
continually enhancing customer service; 2) to maintain competitive electric
rates; 3) to reduce costs to the lowest levels possible without compromising
customer service, employee safety, environmental stewardship, fair
returns to stockholders or fair rewards to employees; and 4) to continue to
expand our core business.
           

ACCOUNTING MATTERS
In October 1996 the American Institute of Certified Public Accountants issued
Statement of Position 96-1, "Environmental Remediation Liabilities" (SOP 96-1).
This statement establishes standards for the recognition, measurement, display
and disclosure of environmental remediation liabilities. SOP 96-1 is effective
January 1, 1997, and is not expected to have a material effect on the Company's
financial position or results of operations upon adoption.


EFFECTS OF INFLATION AND CHANGING PRICES
The current replacement cost of the Company's utility plant substantially
exceeds its recorded historical cost. Under existing regulatory practice, only
the historical cost of plant is recoverable from customers. As a result, cash
flows designed to provide recovery of historical plant costs through
depreciation may not be adequate to replace plant in future years. However,
past practice indicates Union Electric will be allowed to earn on and to
recover the increased cost of replacing facilities when this occurs. The impact
on common stockholders is mitigated to the extent depreciable property is
financed with debt that is repaid with dollars of less purchasing power.


SAFE HARBOR STATEMENT

Statements made in this annual report to stockholders which are not based on
historical facts are forward-looking and, accordingly, involve risks and
uncertainties that could cause actual results to differ materially from those
discussed. Although such forward-looking statements have been made in good
faith and are based on reasonable assumptions, there is no assurance that the
expected results will be achieved. These statements include (without
limitation) statements as to future expectations, beliefs, plans, strategies,
objectives, events, conditions and financial performance. In connection with
the "Safe Harbor" provisions of the Private Securities Litigation Reform Act of
1995, the Company is providing the following cautionary statement to identify
important factors that could cause actual results to differ materially from
those anticipated. Factors include, but are not limited to, the effects of:
regulatory actions; changes in laws and other governmental actions;
competition; business and economic conditions; weather conditions; fuel prices
and availability; generation plant performance; monetary and fiscal policies;
and legal and administrative proceedings.

The first and second quarters of 1996 included credits to Missouri electric
customers which reduced net income and earnings on common stock approximately
$13.5 million and $32 million, or 8c. per share and 18c. per share,
respectively. In addition, a 1.8% 1995 rate decrease for Missouri electric
customers reduced net income and earnings on common stock for the first, second
and third quarters of 1996 by $4.2 million, $5.2 million and $2.5 million, or
4c. per share, 5c. per share and 3c. per share, respectively. Fourth quarter
1996 included Callaway plant refueling expenses which decreased net income and
earnings on common stock approximately $18 million, or 18c. per share. Second
quarter 1995 included Callaway plant refueling expenses which decreased net
income and earnings on common stock approximately $20 million, or 20c. per
share. Third quarter 1995 reflected a one-time credit to Missouri electric
customers which reduced net income and earnings on common stock approximately
$18 million, or 18c. per share. In addition, the 1995 rate decrease reduced net
income and earnings on common stock $4 million, or 4c. per share, in both the
third and fourth quarters of 1995. Also, merger-related expenses of $9 million,
which were classified in other income and deductions, reduced net income and
earnings on common stock approximately 9c. per share in the third quarter of
1995. Other changes in quarterly earnings are due to the effect of weather on
sales and other factors that are characteristic of public utility operations.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 - SUMMARY OF ACCOUNTING POLICIES
The Company is regulated by the Missouri Public Service Commission (MoPSC),
Illinois Commerce Commission (ICC), and the Federal Energy Regulatory
Commission (FERC).  The accounting policies of the Company are in accordance
with the ratemaking practices of the regulatory authorities having jurisdiction
and, as such, conform to generally accepted accounting principles, as applied
to regulated public utilities.  Following is a description of the Company's
significant accounting policies:

PROPERTY AND PLANT
The cost of additions to and betterments of units of property and plant is
capitalized.  Cost includes labor, material, applicable taxes, and overheads,
plus an allowance for funds used during construction. Maintenance expenditures
and the renewal of items not considered units of property are charged to income
as incurred.  When units of depreciable property are retired, the original cost
and removal cost, less salvage, are charged to accumulated depreciation.

DEPRECIATION
Depreciation is provided over the estimated lives of the various classes of
depreciable property by applying composite rates on a straight-line basis.  The
provision for depreciation in 1996, 1995 and 1994 was approximately 3% of the
average depreciable cost.

NUCLEAR FUEL
The cost of nuclear fuel is amortized to fuel expense on a unit-of-production
basis.  Spent fuel disposal cost is charged to expense based on kilowatthours
sold.

INCOME TAXES
Deferred tax assets and liabilities are recognized for the tax consequences of
transactions that have been treated differently for financial reporting and tax
return purposes, measured using statutory tax rates.
     Investment tax credits utilized in prior years were deferred and are being
amortized over the useful lives of the properties to which they relate.

ALLOWANCE FOR FUNDS USED DURING CONSTRUCTION
Allowance for funds used during construction (AFC) is a utility industry
accounting practice whereby the cost of borrowed funds and the cost of equity
funds (preferred and common stockholders' equity) applicable to the Company's
construction program are capitalized as a cost of construction.  This
accounting practice offsets the effect on earnings of the cost of financing
current construction, and treats such financing costs in the same manner as
construction charges for labor and materials.
     Under accepted rate-making practice, cash recovery of AFC, as well as
other construction costs, occurs when completed projects are placed in service
and reflected in customer rates.
     AFC rates are determined by the Company consistent with  the methodology
prescribed by the FERC. Average annual AFC rates were 9.0% in 1996, 9.3% in
1995 and 8.9% in 1994.

UNAMORTIZED DEBT DISCOUNT, PREMIUM AND EXPENSE
Discount, premium and expense associated with long-term debt are amortized over
the lives of the related issues.

REVENUE
The Company accrues on its books estimated, but unbilled, revenue.
     Operating Revenues include excise taxes of $99.3 million, $99.2 million
and $97.9 million for the years 1996, 1995 and 1994, respectively.

STOCK COMPENSATION PLANS
The Company applies Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" (ABP 25) in accounting for its plans.

USE OF ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make certain estimates and
assumptions.  Such estimates and assumptions may affect reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reported period.  Actual results could differ from those
estimates.

RECLASSIFICATIONS
Certain reclassifications have been made to prior-year financial statements to
conform with 1996 reporting (see Note 3 - Regulatory Matters).

NOTE 2 - MERGER AGREEMENT
On August 11, 1995, the Company entered into an Agreement and Plan of Merger
(the Merger Agreement) with CIPSCO Incorporated (CIPSCO) and Ameren Corporation
(Ameren), a newly formed entity, 50% owned by the Company and 50% owned by
CIPSCO, pursuant to which, among other things, the Company and CIPSCO will be
merged with Ameren (the Merger).  Subsequent to the Merger, the Company and
Central Illinois Public Service Company (CIPS) and CIPSCO Investment Company
(wholly owned subsidiaries of CIPSCO), will continue as wholly owned operating
subsidiaries of


                                       29

NOTES TO FINANCIAL STATEMENTS

Ameren.  As a result of the Merger, each outstanding share of the Company's 
common stock will be converted into the right to receive one share of
Ameren Common Stock; each outstanding share of the Company's preferred stock
will remain outstanding and unchanged; and each outstanding share of CIPSCO's
common stock will be converted into the right to receive 1.03 shares of Ameren
Common Stock (or cash in lieu of fractional shares).  The Merger is expected to
be tax-free for income tax purposes and will be accounted for under the
"pooling of interests" method of accounting.
     With their execution and delivery of the Merger Agreement, the Company and
CIPSCO entered into stock option agreements, pursuant to one of which the
Company granted CIPSCO the right, upon the terms and subject to the conditions
set forth therein, to purchase up to 6,983,233 shares of the Company's common
stock at a price of $35.94 per share.  Pursuant to the other agreements, CIPSCO
granted the Company the right, upon the terms and subject to the conditions set
forth therein, to purchase up to 6,779,838 shares of CIPSCO common stock at a
price of $37.02 per share.  These options will expire upon consummation of the
Merger.
     After the Merger, Ameren will become a registered public utility holding
company under the Public Utility Holding Company Act of 1935, as
amended.  In December 1995, the Merger was approved by the shareholders of
Union Electric and CIPSCO.  However, the Merger is still conditioned upon,
among other things, receipt of certain regulatory and governmental approvals
(See Note 3 - Regulatory Matters).
     The following unaudited pro forma financial information reflects the
effects of combining Union Electric and CIPSCO into Ameren under the pooling of
interests method of accounting.

and CIPS.


NOTE 3 - REGULATORY MATTERS

On July 21, 1995, the MoPSC approved an agreement involving the
Company's Missouri electric rates.  The agreement decreased rates 1.8% for all
classes of Missouri retail electric customers, effective August 1, 1995,
reducing annual revenues by about $30 million and reducing annual earnings by
approximately 18 cents per share.  In addition, a one-time $30 million credit
to retail Missouri electric customers reduced 1995 earnings approximately 18
cents per share. Also included is a three-year experimental alternative
regulation plan that provides that earnings in any future years in excess of a
12.61% regulatory return on equity (ROE) will be shared equally between
customers and stockholders, and earnings above a 14% ROE will be credited to
customers.  The formula for computing the credit uses twelve-month results
ending June 30, rather than calendar year earnings.  The agreement also
provides that no party shall file for a general increase or decrease in the
Company's Missouri retail electric rates prior to July 1, 1998, except that the
Company may file for an increase if certain adverse events occur.  During 1996,
the Company recorded a $47 million credit for the first year of the plan, which
reduced earnings by $28 million, or 27 cents per share.  This credit was
reflected as a reduction in electric revenues.  At this time, the Company is
unable to determine whether it will be required to make any future credits to
its customers under the agreement.
     In 1995, the Company filed an application with the MoPSC for approval of
the Merger.  On July 12, 1996, a joint agreement was filed with the MoPSC that
recommends approval of the merger between the Company and CIPSCO.  The Company,
the Missouri Public Service Commission staff, the Office of the Public Counsel,
several customer groups and others signed the agreement.  Agreement provisions
include a new three-year experimental alternative regulation plan that would
run from July 1, 1998, through June 30, 2001.  Like the current plan, the new
plan provides that earnings over a 12.61% ROE up to a 14% ROE would be shared
equally between customers and shareholders.  The new three-year plan would also
return to customers 90% of all earnings above a 14% ROE up to a 16% ROE.
Earnings above a 16% ROE would be credited entirely to customers.  Other
agreement provisions include:  recovery over a 10-year period of the Missouri
portion of an estimated $71.5 million of merger-related expenses; a Missouri
electric rate decrease, effective September 1, 1998, based on the
weather-adjusted average annual credits to customers under the current
experimental alternative regulation plan; and an experimental retail wheeling
pilot program for 100 megawatts of electric power.  Also, as part of the
agreement, the Company would not seek to recover in Missouri the merger
premium.  The exclusion of the merger premium from rates would not result in a
charge to earnings.  On September 25, 1996, the MoPSC ordered that additional
information be filed in November 1996 in connection with the merger proceeding.

     In 1995, the Company and CIPSCO filed joint applications for approval of 
the merger with the ICC and the FERC.  In those applications, the
Company and CIPSCO are requesting a sharing of merger savings, net of merger
premium and merger expenses, between ratepayers and shareholders for the first
10 years subsequent to the Merger.

     On November 7, 1996, a Hearing Examiner for the ICC issued a proposed
order in connection with the Company and CIPSCO's merger proceedings.  In the
proposed order, the Hearing Examiner recommended that the merger between the
Company and CIPSCO be approved.  In addition, the Hearing Examiner recommended
that a decision on the Company and CIPSCO's proposals for sharing net merger
savings be made after the merger.  The Company and CIPSCO would be required to
file a rate case or alternative regulation plan within one year after closing
of the merger whereby an appropriate sharing of net merger savings between
stockholders and customers would be determined at that time. On January 27,
1997, the ICC ordered that additional information be filed in connection with
the merger proceedings.
     On October 16, 1996, the FERC set the proposed merger for hearing.  The
FERC directed the presiding administrative law judge (ALJ) in the case to issue
an initial decision no later than April 30, 1997.
     On December 18, 1996, the FERC issued Order 592 relating to the
Commission's merger policy. The Company believes its proposed merger with
CIPSCO meets the criteria set forth in Order 592, but the effect of this order
on the timing of the ALJ's initial decision is uncertain.
     In October 1996 the Company and CIPSCO filed an application with the
Securities and Exchange Commission for approval of the Merger pursuant to the
Public Utility Holding Company Act of 1935.
     At this time, the Company expects to receive all required regulatory
approvals and to complete the merger by the end of 1997.
     On April 24, 1996, the FERC issued Order 888 and Order 889 related to the
industry's wholesale electric business.  On July 9, 1996, the Company filed an
open access tariff under Order 888.  On September 25, 1996, the FERC set the
open access tariff filing for hearing.  The hearings are scheduled to begin May
1997.
     In October 1996 the Company resolved various financial reporting matters
with the FERC.  The resolution of these matters resulted in the
reclassification of certain costs from electric plant and nuclear fuel in
process to other regulatory assets, as well as the reclassification of
interchange sales from purchased power expenses to electric revenues.  These
reclassifications were made to all prior-year financial statements to conform
with 1996 reporting.  These reclassifications did not have a material effect on
the Company's financial position, results of operations or liquidity.
     In accordance with SFAS No. 71, "Accounting for the Effects of Certain
Types of Regulation," the Company has deferred certain costs pursuant to
actions of its regulators, and is recovering such costs in electric rates
charged to customers.
     At December 31, the Company had recorded the following regulatory assets
and regulatory liability (in thousands):

INCOME TAXES: SEE NOTE 8 - INCOME TAXES.
CALLAWAY COSTS: Represents Callaway nuclear plant operations and maintenance
expenses, property taxes and carrying costs incurred between the plant
in-service date and the date the plant was reflected in rates.  These costs are
being amortized over the remaining life of the plant (through 2024).
CONTRACT TERMINATION COSTS: Represents costs incurred for terminating a nuclear
fuel purchase contract.  These costs are being amortized over the remaining
life of the terminated contract (through 2001).
DEPARTMENT OF ENERGY (DOE) DECOMMISSIONING ASSESSMENT:  Represents fees
assessed by the DOE to decommission its uranium enrichment facility.  These
costs are being amortized through 2007 as payments are made to the DOE.
UNAMORTIZED LOSS ON REACQUIRED DEBT: Represents losses related to refunded
debt. These amounts are being amortized over the lives of the related new debt
issues or the remaining lives of the old debt issues if no new debt was issued.
     The Company continually assesses the recoverability of its regulatory
assets.  Under current accounting standards, regulatory assets are written off
to earnings when it is no longer probable that such amounts will be recovered
through future revenues.


NOTE 4 - DEBT RETIREMENT PROVISIONS
During the five years from December 31, 1996, the amounts of debt maturities
totaling $174 million are: $74 million in 1997; and $100 million in 1999.
Amounts for years subsequent to 1997 do not include nuclear fuel lease payments
since the amounts of such payments are not currently determinable.


NOTE 5 - SHORT-TERM BORROWINGS
Short-term borrowings of the Company consist of bank loans (maturities
generally on an overnight basis) and commercial paper (maturities generally
within 10-45 days). At December 31, 1996, $11.3 million of bank loans were
outstanding. The weighted average interest rates on borrowings outstanding at
December 31, 1996 and 1995, were 7.1% and 6.1%, respectively.

NOTES TO FINANCIAL STATEMENTS

     At December 31, 1996, the Company had committed bank lines of credit
aggregating $179 million (of which $168 million were unused) which make
available interim financing at various rates of interest based on LIBOR, the
bank certificate of deposit rate, or other options. These lines of credit are
renewable annually at various dates throughout the year.

NOTE 6 - NUCLEAR FUEL LEASE
The Company has a lease agreement which provides for the financing of nuclear
fuel.  At December 31, 1996, the maximum amount that could be financed under
the agreement was $120 million. Pursuant to the terms of the lease, the Company
has assigned to the lessor certain contracts for purchase of nuclear fuel. The
lessor obtains, through the issuance of commercial paper or from direct loans
under a committed revolving credit agreement from commercial banks, the
necessary funds to purchase the fuel and make interest payments when due.
     The Company is obligated to reimburse the lessor for all expenditures for
nuclear fuel, interest and related costs. Obligations under this lease become
due as the nuclear fuel is consumed at the Company's Callaway nuclear plant.
The Company reimbursed the lessor $37.5 million during 1996, $34.1 million
during 1995 and $34.5 million during 1994.
     The Company has capitalized the cost, including certain interest costs, of
the leased nuclear fuel and has recorded the related lease obligation.  During
the years 1996, 1995 and 1994, the total interest charges under the lease were
$5.8 million, $5.8 million and $5.2 million, respectively (based on average
interest rates of 5.7%, 6.1% and 4.7%, respectively) of which $3.4 million,
$2.5 million and $2.7 million, respectively, were capitalized.

NOTE 7 -  PREFERRED STOCK
The Company retired 260 shares, $6.30 Series preferred stock in each of the
years 1996, 1995 and 1994.
     On January 21, 1997, the Company redeemed $63.9 million of preferred stock
(see Statement of Preferred Stock for preferred stock series redeemed).

NOTE 8 - INCOME TAXES
Total income tax expense for 1996 resulted in an effective tax rate of 39% on
earnings before income taxes (40% in 1995 and 39% in 1994).

     Principal reasons such rates differ from the statutory federal rate:

     The Company recognizes the income tax effects of temporary differences.
Prior to 1993, in accordance with accepted ratemaking practice, deferred income
taxes were not provided for certain temporary differences flowed through to 
customers and the equity component of AFC.  In accordance with SFAS No. 109,
"Accounting for Income  Taxes," a regulatory asset, representing the probable
recovery from customers of future income taxes which is expected to occur when
temporary differences reverse, was recorded along with a corresponding deferred
tax liability. Also, a regulatory liability, recognizing the lower expected
revenue resulting from reduced income taxes associated with amortizing
accumulated deferred investment tax credits, was recorded.

     The Company adjusts its deferred tax liabilities for changes enacted in
tax laws or rates.  Recognizing that regulators will probably reduce future
revenues for deferred tax liabilities initially recorded at rates in excess of
the current statutory rate, reductions in the deferred tax liability were
credited to the regulatory liability.
     Temporary differences gave rise to the following deferred tax assets and
deferred tax liabilities at December 31 (in millions):

NOTE 9 - RETIREMENT BENEFITS

The Company has non-contributory, defined-benefit retirement plans covering
substantially all of its employees. Benefits are based on the employees' years
of service and compensation. The Company's funding policy is to contribute
annually at least the minimum amount required by government funding standards,
but not more than can be deducted for federal income taxes. Plan assets consist
principally of common stocks and fixed income securities.
     Pension costs for the years 1996, 1995 and 1994, were $28 million, $26
million and $31 million, respectively, of which 19% was charged to construction
accounts in 1996 , 20% in 1995 and 18% in 1994.

     In addition to providing pension benefits, the Company provides certain
health care and life insurance benefits for retired employees. Substantially
all of the Company's employees may become eligible for those benefits if they
reach retirement age while working for the Company. The Company's funding
policy is to contribute annually the net periodic cost. Plan assets consist
principally of common stocks and fixed income securities.
     The Company accrues the expected postretirement benefit costs during
employees' years of service. Postretirement benefit costs were $44 million for
each of the years 1996 and 1995 and $46 million for 1994, of which
approximately 19% was charged to construction accounts in each of the three
years. The Company's transition obligation at December 31, 1996, is being
amortized over the next 16 years.
     In August 1994, the MoPSC authorized the recovery of postre-tirement
benefit costs in rates to the extent that such costs are funded. In December
1995, the Company established two external trust funds for retiree healthcare
and life insurance benefits. For both 1995 and 1994, actual claims paid were
approximately $15 million. In 1996, claims were paid out of the plan trust
funds.

NOTE 10 - STOCK OPTION PLANS

In April, 1995, the Company's shareholders approved a Long-Term
Incentive Plan (the Plan) for eligible employees, as determined by the Human
Resources Committee of the Board.  The Plan provides for the grant of options,
performance awards, restricted stock, dividend equivalents and stock
appreciation rights.   Under the terms of the Plan, options may be granted at a
price not less than the fair market value of the shares at the date of grant.
Granted options vest over a period of five years, beginning at the date of
grant, and provide for acceleration of exercisability of the options upon the
occurrence of certain events, including retirement.  Outstanding options expire
on various dates through 2006.  Under the Plan, subject to adjustment as
provided in the Plan, 2.5 million shares have been authorized to be issued or
delivered.  The Company expects to make open market purchases of its common
stock to meet the requirements of the Plan.

     In accordance with APB 25, no compensation cost has been recognized for
the Company's stock compensation plans.  In 1996, Union Electric adopted the
disclosure-only method under SFAS 123, "Accounting for Stock-Based
Compensation."  If the fair value based accounting method under this statement
had been used to account for stock-based compensation cost, the effects on 1996
and 1995 net income and earnings per share would have been immaterial.


NOTE 11 - COMMITMENTS

The Company is engaged in a construction program under which expenditures
averaging approximately $267 million, including AFC, are anticipated during
each of the next five years.
     The Company has commitments for the purchase of coal under long-term
contracts.  Coal contract commitments, including transportation costs, for 1997
through 2001 are estimated to total $789 million (excluding contract escalation
provisions).  Total coal purchases, including transportation costs, for 1996,
1995 and 1994 were $270 million, $293 million and $268 million, respectively.
The Company also has existing contracts with pipeline and natural gas suppliers
to provide natural gas for distribution and electric generation. Gas-related
contracted cost commitments for 1997 through 2001 are estimated to total $99
million. Total delivered natural gas costs for 1996, 1995 and 1994 were $64
million, $60 million and $63 million, respectively.  The Company's nuclear fuel
commitments for 1997 through 2001, including uranium concentrates, conversion,
enrichment and fabrication, are expected to total $126 million, and are
expected to be financed under the nuclear fuel lease.  Nuclear fuel
expenditures for 1996, 1995 and 1994 were $51 million, $42 million and $30
million, respectively. In addition, the Company has long-term contracts with
other utilities to purchase electric capacity. These commitments for 1997
through 2001 are estimated to total $201 million. During 1996, 1995 and 1994,
electric capacity purchases were $44 million, $42 million and $38 million,
respectively.

(a)  Retrospective premium under the Price-Anderson liability provisions of
     the Atomic Energy Act of 1954, as amended, (Price-Anderson). Subject to
     retrospective assessment with respect to loss from an incident at any U.S.
     reactor, payable at $10 million per year.
(b)  Limit of liability for each incident under Price-Anderson.
(c)  Total industry potential liability from workers claiming exposure to the
     hazard of nuclear radiation. The policy includes an automatic
     reinstatement thereby providing total coverage of $400 million.
(d)  Includes premature decommissioning costs.
(e)  Weekly indemnity of $3.1 million, for 52 weeks which commences after the
     first 21 weeks of an outage, plus $2.5 million per week for 104 weeks
     thereafter.


     Price-Anderson limits the liability for claims from an incident involving
any licensed U.S. nuclear facility. The limit is based on the number of
licensed reactors and is adjusted at least every five years based on the
Consumer Price Index. Utilities owning a nuclear reactor cover this exposure
through a combination of private insurance and mandatory participation in a
financial protection pool as established by Price-Anderson.
     If losses from a nuclear incident at Callaway Plant exceed the limits of,
or are not subject to, insurance, or if coverage is not available, the Company
will self-insure the risk. Although the Company has no reason to anticipate a
serious nuclear incident, if one did occur it could have a material but
undeterminable adverse effect on the Company's financial position, results of
operations or liquidity.
     Under the Clean Air Act Amendments of 1990, the Company is required to
reduce total annual sulfur dioxide emissions significantly by the year 2000.
Significant reductions in nitrogen oxide are also required. By switching to
low-sulfur coal and early banking of emission credits, the Company anticipates
that it can comply with the requirements of the law without significant revenue
increases because the related capital costs, estimated at about $300 million,
are largely offset by lower fuel costs. As of year-end 1996, about 84% of the
Clean Air Act-related capital costs had been expended.
     As of December 31, 1996, the Company was designated a potentially
responsible party (PRP) by federal and state environmental protection agencies
at four hazardous waste sites. Other hazardous waste sites have been identified
for which the Company may be responsible but has not been designated a PRP. The
Company continually reviews the remediation costs that may be required for all
of these sites. However, such costs are not expected to have a material adverse
effect on the Company's financial position, results of operations or liquidity.
     Regulatory changes enacted and being considered at the federal and state
levels continue to change the structure of the industry and utility regulation,
as well as encourage increased competition. At this time, the Company is unable
to predict the impact of these changes on the Company's future financial
condition, results of operations or liquidity.
     The Company is involved in legal and administrative proceedings before
various courts and agencies with respect to matters arising in the ordinary
course of business, some of which involve substantial amounts. The Company
believes that the final disposition of these proceedings will not have a
material adverse effect on its financial position, results of operations or
liquidity.


NOTE 13 - CALLAWAY NUCLEAR PLANT

Under the Nuclear Waste Policy Act of 1982, the DOE is responsible for the
permanent storage and disposal of spent nuclear fuel. DOE currently charges one
mill per nuclear generated kilowatthour sold for future disposal of spent fuel.
Electric rates charged to customers provide for recovery of such costs. DOE is
not expected to have its permanent storage facility for spent fuel available
until at least 2015. The Company has sufficient storage capacity at the
Callaway Plant site until 2005 and has viable storage alternatives under
consideration. Each alternative will likely require Nuclear Regulatory
Commission approval and may require other regulatory approvals. The delayed
availability of DOE's disposal facility is not expected to adversely affect the
continued operation of Callaway Plant.
     Electric rates charged to customers provide for recovery of Callaway Plant
decommissioning costs over the life of the plant, based on an assumed 40-year
life, ending with expiration of the plant's operating license in 2024. The
Callaway site is assumed to be decommissioned using the DECON (immediate        
dismantlement) method. Decommissioning costs, including decontamination,
dismantling and site restoration, are estimated to be $420 million in current
year dollars and are expected to escalate approximately 4% per year through the
end of decommissioning activity in 2033. Decommissioning cost is charged to
depreciation expense over Callaway's service life and


                                      35

NOTES TO FINANCIAL STATEMENTS

amounted to $6.7 million in each of the years 1996, 1995 and 1994. Every three
years, the MoPSC requires the Company to file updated cost studies for
decommissioning Callaway, and electric rates may be adjusted at such times to
reflect changed estimates. The latest study was performed in 1996. Costs
collected from customers are deposited in an external trust fund to provide for
Callaway's decommissioning. Fund earnings are expected to average 9.25%
annually through the date of decommissioning. If the assumed return on trust
assets is not earned, the Company believes it is probable that such earnings
deficiency will be recovered in rates. Trust fund earnings, net of expenses,
appear on the balance sheet as increases in nuclear decommissioning trust fund
and in the accumulated provision for nuclear decommissioning.
     The staff of the Securities and Exchange Commission has questioned certain
of the current accounting practices of the electric utility industry, regarding
the recognition, measurement and classification of decommissioning costs for
nuclear generating stations in the financial statements of electric utilities.
In response to these questions, the Financial Accounting Standards Board has
agreed to review the accounting for removal costs, including decommissioning.
If current electric utility industry accounting practices for such
decommissioning are changed, (1) the annual provisions for decommissioning
could increase, and (2) trust fund income from the external decommissioning
trusts could be reported as investment income rather than as a reduction to
decommissioning expense. The Company does not expect that changes in the
accounting for nuclear decommissioning costs will have a material effect on its
financial position, results of operations or liquidity.


NOTE 14 - FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate
that value.

CASH AND TEMPORARY INVESTMENTS/SHORT-TERM BORROWINGS

The carrying amounts approximate fair value because of the short-term maturity
of these instruments.

NUCLEAR DECOMMISSIONING TRUST FUND

The fair value of the Company's nuclear decommissioning trust fund is estimated
based on quoted market prices for securities.

PREFERRED STOCK

The fair value of the Company's preferred stock outstanding is estimated based
on the quoted market prices for the same or similar issues.

LONG-TERM DEBT

The fair value of the Company's long-term debt is estimated based on the quoted
market prices for the same or similar issues or on the current rates offered to
the Company for debt of comparable maturities.

     The Company has investments in debt and equity securities that are held in
trust funds for the purpose of funding the nuclear decommissioning of the
Callaway nuclear plant (see Note 13 - Callaway Nuclear Plant).  The Company has
classified these investments in debt and equity securities as available for
sale and has recorded all such investments at their fair market value at
December 31, 1996 and 1995.  In 1996, 1995 and 1994, the proceeds from the sale
of investments were $19.6 million, $9.4 million and $22.2 million,
respectively.  Using the specific identification method to determine cost, the
gross realized gains on those sales were approximately $1 million for 1996,
1995 and 1994.  Net realized and unrealized gains and losses are reflected in
accumulated provision for nuclear decommissioning on the Balance Sheet, which
is consistent with the method used by the Company to account for the
decommissioning costs recovered in rates.
