             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
1. INTRODUCTION AND BASIS OF PRESENTATION
 
 The Merger
 
  On May 31, 1997, Morgan Stanley Group Inc. ("Morgan Stanley") was merged
with and into Dean Witter, Discover & Co. ("Dean Witter Discover") (the
"Merger"). At that time, Dean Witter Discover changed its corporate name to
Morgan Stanley, Dean Witter, Discover & Co. ("MSDWD"). In conjunction with the
Merger, MSDWD issued 260,861,078 shares of its common stock, as each share of
Morgan Stanley common stock then outstanding was converted into 1.65 shares of
MSDWD's common stock (the "Exchange Ratio"). In addition, each share of Morgan
Stanley preferred stock was converted into one share of a corresponding series
of preferred stock of MSDWD. The Merger was treated as a tax-free exchange.
 
  On March 24, 1998, MSDWD changed its corporate name to Morgan Stanley Dean
Witter & Co. (the "Company").
 
 The Company
 
  The condensed consolidated financial statements include the accounts of
Morgan Stanley Dean Witter & Co. and its U.S. and international subsidiaries,
including Morgan Stanley & Co. Incorporated ("MS&Co."), Morgan Stanley & Co.
International Limited ("MSIL"), Morgan Stanley Japan Limited ("MSJL"), Dean
Witter Reynolds Inc. ("DWR"), Dean Witter InterCapital Inc. and NOVUS Credit
Services Inc.
 
  The Company, through its subsidiaries, provides a wide range of financial
and securities services on a global basis and provides credit and transaction
services nationally. Its securities and asset management businesses include
securities underwriting, distribution and trading; merger, acquisition,
restructuring, real estate, project finance and other corporate finance
advisory activities; asset management; private equity and other principal
investment activities; brokerage and research services; the trading of foreign
exchange and commodities as well as derivatives on a broad range of asset
categories, rates and indices; and global custody, securities clearance
services and securities lending. The Company's credit and transaction services
businesses include the operation of the NOVUS Network, a proprietary network
of merchant and cash access locations, and the issuance of the Discover(R)
Card and other proprietary general purpose credit cards. The Company's
services are provided to a large and diversified group of clients and
customers, including corporations, governments, financial institutions and
individuals.
 
 Basis of Financial Information and Change in Fiscal Year End
 
  The condensed consolidated financial statements give retroactive effect to
the Merger, which was accounted for as a pooling of interests. The pooling of
interests method of accounting requires the restatement of all periods
presented as if Dean Witter Discover and Morgan Stanley had always been
combined.
 
  Prior to the Merger, Dean Witter Discover's year ended on December 31 and
Morgan Stanley's fiscal year ended on November 30. Subsequent to the Merger,
the Company adopted a fiscal year end of November 30. All information included
herein for the quarter ended February 28, 1997 reflects the change in fiscal
year end.
 
  The condensed consolidated financial statements are prepared in accordance
with generally accepted accounting principles, which require management to
make estimates and assumptions regarding certain trading inventory valuations,
consumer loan loss levels, the potential outcome of litigation and other
matters that affect the financial statements and related disclosures.
Management believes that the estimates utilized in the preparation of the
condensed consolidated financial statements are prudent and reasonable. Actual
results could differ materially from these estimates.
 
  Certain reclassifications have been made to prior year amounts to conform to
the current presentation. All material intercompany balances and transactions
have been eliminated.

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The condensed consolidated financial statements should be read in
conjunction with the Company's consolidated financial statements and notes
thereto included in the Company's Annual Report on Form 10-K (the "Form 10-K")
for the fiscal year ended November 30, 1997. The condensed consolidated
financial statements reflect all adjustments (consisting only of normal
recurring adjustments) which are, in the opinion of management, necessary for
the fair statement of the results for the interim period. The results of
operations for interim periods are not necessarily indicative of results for
the entire year.
 
  Financial instruments, including derivatives, used in the Company's trading
activities are recorded at fair value, and unrealized gains and losses are
reflected in trading revenues. Interest revenue and expense arising from
financial instruments used in trading activities are reflected in the
condensed consolidated statements of income as interest revenue or expense.
The fair values of trading positions generally are based on listed market
prices. If listed market prices are not available or if liquidating the
Company's positions would reasonably be expected to impact market prices, fair
value is determined based on other relevant factors, including dealer price
quotations and price quotations for similar instruments traded in different
markets, including markets located in different geographic areas. Fair values
for certain derivative contracts are derived from pricing models which
consider current market and contractual prices for the underlying financial
instruments or commodities, as well as time value and yield curve or
volatility factors underlying the positions. Purchases and sales of financial
instruments are recorded in the accounts on trade date. Unrealized gains and
losses arising from the Company's dealings in over-the-counter ("OTC")
financial instruments, including derivative contracts related to financial
instruments and commodities, are presented in the accompanying condensed
consolidated statements of financial condition on a net-by-counterparty basis,
when appropriate.
 
  Equity securities purchased in connection with private equity and other
principal investment activities are initially carried in the condensed
consolidated financial statements at their original costs. The carrying value
of such equity securities is adjusted when changes in the underlying fair
values are readily ascertainable, generally as evidenced by listed market
prices or transactions which directly affect the value of such equity
securities. Downward adjustments relating to such equity securities are made
in the event that the Company determines that the eventual realizable value is
less than the carrying value. The carrying value of investments made in
connection with principal real estate activities which do not involve equity
securities are adjusted periodically based on independent appraisals,
estimates prepared by the Company of discounted future cash flows of the
underlying real estate assets or other indicators of fair value.
 
  Loans made in connection with private equity and investment banking
activities are carried at cost plus accrued interest less reserves, if deemed
necessary, for estimated losses.
 
  The Company has entered into various contracts as hedges against specific
assets, liabilities or anticipated transactions. These contracts include
interest rate swaps, foreign exchange forwards, foreign currency swaps, and
cost of funds agreements. The Company uses interest rate and currency swaps to
manage the interest rate and currency exposure arising from certain borrowings
and to match the refinancing characteristics of consumer loans with the
borrowings that fund these loans. For contracts that are designated as hedges
of the Company's assets and liabilities, gains and losses are deferred and
recognized as adjustments to interest revenue or expense over the remaining
life of the underlying assets or liabilities. For contracts that are hedges of
asset securitizations, gains and losses are recognized as adjustments to
servicing fees. Gains and losses resulting from the termination of hedge
contracts prior to their stated maturity are recognized ratably over the
remaining life of the instrument being hedged. The Company also uses foreign
exchange forward contracts to manage the currency exposure relating to its net
monetary investment in non-U.S. dollar functional currency operations. The
gain or loss from revaluing these contracts is deferred and reported within
cumulative translation adjustments in shareholders' equity, net of tax
effects, with the related unrealized amounts due from or to counterparties
included in receivables from or payables to brokers, dealers and clearing
organizations.

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Earnings Per Share
 
  As of December 1, 1997, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 128, "Earnings per Share" ("SFAS No. 128").
SFAS No. 128 replaces the previous earnings per share ("EPS") categories of
primary and fully diluted with "basic EPS," which reflects no dilution from
common stock equivalents, and "diluted EPS," which reflects dilution from
common stock equivalents and other dilutive securities based on the average
price per share of the Company's common stock during the period. The EPS
amounts of prior periods have been restated in accordance with SFAS No. 128.
The adoption of SFAS No. 128 has not had a material effect on the Company's
EPS calculations.
 
  The calculations of earnings per common share are based on the weighted
average number of common shares and share equivalents outstanding and give
effect to preferred stock dividend requirements. All per share and share
amounts reflect stock splits effected by Dean Witter Discover and Morgan
Stanley prior to the Merger, as well as the additional shares issued to Morgan
Stanley shareholders pursuant to the Exchange Ratio.
 
 Accounting Pronouncements
 
  As of January 1, 1998, the Company adopted SFAS No. 127, "Deferral of the
Effective Date of Certain Provisions of FASB Statement No. 125," which was
effective for transfers and pledges of certain financial assets and collateral
made after December 31, 1997. The adoption of SFAS No. 127 created additional
assets and liabilities on the Company's consolidated statement of financial
condition related to the recognition of securities provided and received as
collateral. At February 28, 1998, the impact of SFAS No. 127 on the Company's
condensed consolidated statement of financial position (excluding
reclassifications) was an increase to total assets and total liabilities of
$13,503 million.
 
  In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting Comprehensive Income" and SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." These statements, which
are effective for fiscal years beginning after December 15, 1997, establish
standards for the reporting and presentation of comprehensive income and the
disclosure requirements related to segments.
 
  In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits," which revises and
standardizes pension and other postretirement benefit plan disclosures that
are to be included in the employers' financial statements. SFAS No. 132 does
not change the measurement or recognition rules for pensions and other
postretirement benefit plans, and is effective for fiscal years beginning
after December 15, 1997.
 
2. CONSUMER LOANS

and $74 million in the quarter ended February 28, 1997.
 
  The Company received proceeds from asset securitizations of $368 million in

5. COMMON STOCK AND SHAREHOLDERS' EQUITY
 
  MS&Co. and DWR are registered broker-dealers and registered futures
commission merchants and, accordingly, are subject to the minimum net capital
requirements of the Securities and Exchange Commission, the New York Stock
Exchange and the Commodity Futures Trading Commission. MS&Co. and DWR have
consistently operated in excess of these net capital requirements. MS&Co.'s
net capital totaled $2,491 million at February 28, 1998 which exceeded the
amount required by $2,026 million. DWR's net capital totaled $626 million at
February 28, 1998 which exceeded the amount required by $549 million. MSIL, a
London-based broker-dealer subsidiary, is subject to the capital requirements
of the Securities and Futures Authority, and MSJL, a Tokyo-based broker-
dealer, is subject to the capital requirements of the Japanese Ministry of
Finance. MSIL and MSJL have consistently operated in excess of their
respective regulatory capital requirements.
 
  Under regulatory net capital requirements adopted by the Federal Deposit
Insurance Corporation ("FDIC") and other regulatory capital guidelines, FDIC
insured financial institutions must maintain (a) 3% to 5% of Tier 1 capital,
as defined, to total assets ("leverage ratio") and (b) 8% combined Tier 1 and
Tier 2 capital, as defined, to risk weighted assets ("risk-weighted capital
ratio"). At February 28, 1998, the leverage ratio and risk-weighted capital
ratio of each of the Company's FDIC-insured financial institutions exceeded
these and all other regulatory minimums.
 
  Certain other U.S. and non-U.S. subsidiaries are subject to various
securities, commodities and banking regulations, and capital adequacy
requirements promulgated by the regulatory and exchange authorities of the
countries in which they operate. These subsidiaries have consistently operated
in excess of their local capital adequacy requirements.

7. COMMITMENTS AND CONTINGENCIES
 
  In the normal course of business, the Company has been named as a defendant
in various lawsuits and has been involved in certain investigations and
proceedings. Some of these matters involve claims for substantial amounts.
Although the ultimate outcome of these matters cannot be ascertained at this
time, it is the opinion of management, after consultation with outside
counsel, that the resolution of such matters will not have a material adverse
effect on the consolidated financial condition of the Company, but may be
material to the Company's operating results for any particular period,
depending upon the level of the Company's net income for such period.
 
  The Company had approximately $5.7 billion and $5.5 billion of letters of
credit outstanding at February 28, 1998 and at November 30, 1997 to satisfy
various collateral requirements.
 
8. DERIVATIVE CONTRACTS
 
  In the normal course of business, the Company enters into a variety of
derivative contracts related to financial instruments and commodities. The
Company uses swap agreements in managing its interest rate exposure. The
Company also uses forward and option contracts, futures and swaps in its
trading activities; these financial instruments also are used to hedge the
U.S. dollar cost of certain foreign currency exposures. In addition, financial
futures and forward contracts are actively traded by the Company and are used
to hedge proprietary inventory. The Company also enters into delayed delivery,
when-issued, and warrant and option contracts involving securities. These
instruments generally represent future commitments to swap interest payment
streams, exchange currencies or purchase or sell other financial instruments
on specific terms at specified future dates. Many of these products have
maturities that do not extend beyond one year; swaps and options and warrants
on equities typically have longer maturities. For further discussion of these
matters, refer to "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Derivative Financial Investments" and Note 8 to the
consolidated financial statements for the fiscal year ended November 30, 1997,
included in the Form 10-K.
 
  These derivative instruments involve varying degrees of off-balance sheet
market risk. Future changes in interest rates, foreign currency exchange rates
or the fair values of the financial instruments, commodities or indices
underlying these contracts ultimately may result in cash settlements exceeding
fair value amounts recognized in the condensed consolidated statements of
financial condition, which, as described in Note 1, are recorded at fair
value, representing the cost of replacing those instruments.
 
  The Company's exposure to credit risk with respect to these derivative
instruments at any point in time is represented by the fair value of the
contracts reported as assets. These amounts are presented on a net-by-
counterparty basis (when appropriate), but are not reported net of collateral,
which the Company obtains with respect to certain of these transactions to
reduce its exposure to credit losses.

  A substantial portion of the Company's securities and commodities
transactions are collateralized and are executed with and on behalf of
commercial banks and other institutional investors, including other brokers
and dealers. Positions taken and commitments made by the Company, including
positions taken and underwriting and financing commitments made in connection
with its private equity and other principal investment activities, often
involve substantial amounts and significant exposure to individual issuers and
businesses, including non-investment grade issuers. The Company seeks to limit
concentration risk created in its businesses through a variety of separate but
complementary financial, position and credit exposure reporting systems,
including the use of trading limits based in part upon the Company's review of
the financial condition and credit ratings of its counterparties.
 
  See also "Risk Management" in the Form 10-K for discussions of the Company's
risk management policies and procedures for its securities businesses.
 
9. SUBSEQUENT EVENTS
 
  On March 26, 1998, the Company announced that it is entering into agreements
to sell its Prime Option MasterCard credit card portfolio, which it operates
in conjunction with NationsBank. The sale is expected to close during the
quarter ending May 31, 1998, and is not expected to have a material effect on
the Company's consolidated financial condition or results of operations. The
Company also announced its decision to discontinue its BRAVO(R) credit card
brand. The Company plans to consolidate the BRAVO portfolio with its Private
Issue and Discover Card brands.
 
  On April 2, 1998, the Company announced that it is exploring the potential
sale of its Global Custody and Correspondent Clearing businesses as part of a
strategic decision to focus on growing its core businesses--Securities and
Asset Management and Credit and Transaction Services.

                        INDEPENDENT ACCOUNTANTS' REPORT
 
To the Directors and Shareholders of
 Morgan Stanley Dean Witter & Co.
 
We have reviewed the accompanying condensed consolidated statement of
financial condition of Morgan Stanley Dean Witter & Co. and subsidiaries
(formerly Morgan Stanley, Dean Witter, Discover & Co.) as of February 28,
1998, and the related condensed consolidated statements of income and cash
flows for the three month periods ended February 28, 1998 and 1997. These
condensed consolidated financial statements are the responsibility of the
management of Morgan Stanley Dean Witter & Co. We were furnished with the
report of other accountants on their review of the interim financial
information of Morgan Stanley Group Inc. and subsidiaries for the quarter
ended February 28, 1997, which statements reflect total revenues of $4,076
million for the three month period ended February 28, 1997.
 
We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures
to financial data and making inquiries of persons responsible for financial
and accounting matters. It is substantially less in scope than an audit
conducted in accordance with generally accepted auditing standards, the
objective of which is the expression of an opinion regarding the financial
statements taken as a whole. Accordingly, we do not express such an opinion.
 
Based on our review and the report of other accountants, we are not aware of
any material modifications that should be made to such condensed consolidated
financial statements for them to be in conformity with generally accepted
accounting principles.
 
We have previously audited, in accordance with generally accepted auditing
standards, the consolidated statement of financial condition of Morgan Stanley
Dean Witter & Co. and subsidiaries as of November 30, 1997, and the related
consolidated statements of income, cash flows and changes in shareholders'
equity for the year then ended (not presented herein), included in Morgan
Stanley Dean Witter & Co.'s Annual Report on Form 10-K for the fiscal year
ended November 30, 1997; and in our report dated January 23, 1998, we
expressed an unqualified opinion on those consolidated financial statements
based on our audit and the report of other auditors.

                      CONDITION AND RESULTS OF OPERATIONS
 
INTRODUCTION
 
 The Merger
 
  On May 31, 1997, Morgan Stanley Group Inc. ("Morgan Stanley") was merged
with and into Dean Witter, Discover & Co. ("Dean Witter Discover") (the
"Merger"). At that time, Dean Witter Discover changed its corporate name to
Morgan Stanley, Dean Witter, Discover & Co. ("MSDWD"). In conjunction with the
Merger, each share of Morgan Stanley common stock then outstanding was
converted into 1.65 shares of MSDWD's common stock and each share of Morgan
Stanley preferred stock was converted into one share of a corresponding series
of preferred stock of MSDWD. The Merger was treated as a tax-free exchange.
 
  On March 24, 1998, MSDWD changed its corporate name to Morgan Stanley Dean
Witter & Co. (the "Company").
 
 Basis of Financial Information and Change in Fiscal Year End
 
  The condensed consolidated financial statements give retroactive effect to
the Merger, which was accounted for as a pooling of interests. The pooling of
interests method of accounting requires the restatement of all periods
presented as if Dean Witter Discover and Morgan Stanley had always been
combined.
 
  Prior to the Merger, Dean Witter Discover's year ended on December 31 and
Morgan Stanley's fiscal year ended on November 30. Subsequent to the Merger,
the Company adopted a fiscal year end of November 30. All information included
herein for the quarter ended February 28, 1997 reflects the change in fiscal
year end.
 
RESULTS OF OPERATIONS*
 
 Certain Factors Affecting Results of Operations
 
  The Company's results of operations may be materially affected by market
fluctuations and economic factors. In addition, results of operations in the
past have been and in the future may continue to be materially affected by
many factors of a global nature, including economic and market conditions; the
availability of capital; the level and volatility of interest rates; currency
values and other market indices; the availability of credit; inflation; and
legislative and regulatory developments. Such factors may also have an impact
on the Company's ability to achieve its strategic objectives, including
(without limitation) profitable global expansion.
 
  The Company's Securities and Asset Management business, particularly its
involvement in primary and secondary markets for all types of financial
products, including derivatives, is subject to substantial positive and
negative fluctuations due to a variety of factors that cannot be predicted
with great certainty, including variations in the fair value of securities and
other financial products and the volatility and liquidity of trading markets.
 
  Fluctuations also occur due to the level of market activity, which, among
other things, affects the flow of investment dollars into mutual funds, and
the size, number and timing of transactions or assignments (including
realization of returns from the Company's private equity investments). In the
Company's Credit and Transaction Services business, changes in economic
variables may substantially affect consumer loan growth and credit quality.
Such variables include the number of personal bankruptcy filings, the rate of
unemployment and the level of consumer debt as a percentage of income.
- --------
* This Management's Discussion and Analysis of Financial Condition and Results
  of Operations contains forward-looking statements, as well as a discussion
  of some of the risks and uncertainties involved in the Company's business
  that could affect the matters referred to in such statements.
 
                                      13
<PAGE>
 
  The Company's results of operations also may be materially affected by
competitive factors. In addition to competition from firms traditionally
engaged in the securities business, there has been increased competition from
other sources, such as commercial banks, insurance companies, mutual fund
groups and other companies offering financial services both in the U.S. and
globally. As a result of recent and pending legislative and regulatory
initiatives in the U.S. to remove or relieve certain restrictions on
commercial banks, competition in some markets that have traditionally been
dominated by investment banks and retail securities firms has increased and
may continue to increase in the near future. In addition, recent and
continuing convergence and consolidation in the financial services industry
will lead to increased competition from larger diversified financial services
organizations.
 
  Such competition, among other things, affects the Company's ability to
attract and retain highly skilled individuals. Competitive factors also affect
the Company's success in attracting and retaining clients and assets by its
ability to meet investors' saving and investment needs through consistency of
investment performance and accessibility to a broad array of financial
products and advice. In the credit services industry, competition centers on
merchant acceptance of credit cards, credit card account acquisition and
customer utilization of credit cards. Merchant acceptance is based on both
competitive transaction pricing and the volume of credit cards in circulation.
Credit card account acquisition and customer utilization are driven by the
offering of credit cards with competitive and appealing features such as no
annual fees, low introductory and attractive interest rates, and other
customized features targeting specific consumer groups and by having broad
merchant acceptance.
 
  As a result of the above economic and competitive factors, net income and
revenues in any particular period may not be representative of full-year
results and may vary significantly from year to year and from quarter to
quarter. The Company intends to manage its business for the long term and help
mitigate the potential effects of market downturns by strengthening its
competitive position in the global financial services industry through
diversification of its revenue sources and enhancement of its global
franchise. The Company's ability and success in maintaining high levels of
profitable business activities, emphasizing fee-based assets that are designed
to generate a continuing stream of revenues, managing risks in both the
Securities and Asset Management and Credit and Transaction Services
businesses, evaluating credit product pricing and monitoring costs will
continue to affect its overall financial results. In addition, the
complementary trends in the financial services industry of consolidation and
globalization present, among other things, technological, risk management and
other infrastructure challenges that will require effective resource
allocation in order for the Company to remain competitive.
 
 Economic and Market Conditions in the First Fiscal Quarter of 1998
 
  The favorable economic and market conditions that characterized the global
financial markets in fiscal 1997 continued through much of the first fiscal
quarter of 1998. After three unprecedented years of share price gains, U.S.
financial markets continued to strengthen in an environment characterized by
solid economic expansion and continued heavy cash flows into mutual funds.
Expectations of continued merger and consolidation activity also contributed
to increasing equity share prices. Despite continued turmoil and uncertainty
relating to the economic situation in Asia, the U.S. economy continued to
exhibit signs of growth, and strong corporate earnings and high levels of
consumer confidence persisted. Nevertheless, the levels of inflation and
interest rates remained relatively low, and the Federal Reserve Board has not
altered the overnight lending rate since March 1997. While the overall
performance of U.S. financial markets continued to be favorable, such
performance was, at times, volatile, partly due to concerns of lower corporate
earnings resulting from the difficult economic situation in Asia.
 
  Conditions in most European markets were also favorable during the quarter,
primarily due to strong corporate earnings and stable economic conditions.
Most major stock exchanges reached record levels as interest and inflation
rates in many European nations declined due to increasing certainty that the
first phase of the approaching European Economic and Monetary Union ("EMU")
would be implemented on schedule.
 
  Market conditions in the Far East were dominated by the continuing economic
and financial difficulties existing in the region since the latter half of
fiscal 1997. Japan's rate of economic growth has continued to lag,
 
                                      14
<PAGE>
 
and the future effect of its government's measures to stimulate the economy
remained uncertain. Market conditions were also unstable elsewhere in Asia, as
uncertainty surrounding Indonesia's compliance with fiscal requirements
established by the International Monetary Fund led to a further weakening of
investor confidence. In addition, the currencies of many nations in the region
declined to record lows during the quarter.
 
 First Fiscal Quarter 1998 and 1997 Results of the Company
 
  The Company's net income of $691 million in the quarter ended February 28,
1998 represented an increase of 21% from the comparable period of fiscal 1997.
Diluted earnings per common share were $1.10 in the quarter ended February 28,
1998 as compared to $0.91 in the quarter ended February 28, 1997. The
Company's annualized return on common equity was 20.1% for the quarter ended
February 28, 1998, as compared with 20.7% for the quarter ended February 28,
1997.
 
  The increase in net income in the quarter ended February 28, 1998 from the
comparable prior year period was due to higher revenues from securities
activities, including investment banking, principal transactions and
commissions, as well as increased asset management, distribution and
administration fees. These increases were partially offset by higher non-
interest expenses coupled with lower earnings from the Company's Credit and
Transaction Services business, primarily due to higher credit card net charge-
offs.
 
  On March 26, 1998, the Company announced that it is entering into agreements
to sell its Prime Option MasterCard credit card portfolio, which it operates
in conjunction with NationsBank. The sale is expected to close during the
quarter ending May 31, 1998, and is not expected to have a material effect on
the Company's consolidated financial condition or results of operations. The
Company also announced its decision to discontinue its BRAVO(R) credit card
brand. The Company plans to consolidate the BRAVO portfolio with its Private
Issue and Discover Card brands.
 
  On April 2, 1998, the Company announced that it is exploring the potential
sale of its Global Custody and Correspondent Clearing businesses as part of a
strategic decision to focus on growing its core businesses--Securities and
Asset Management and Credit and Transaction Services.
 
  The remainder of Results of Operations is presented on a business segment
basis. Substantially all of the operating revenues and operating expenses of
the Company can be directly attributable to its two business segments:
Securities and Asset Management and Credit and Transaction Services. Certain
reclassifications have been made to prior-period amounts to conform to the
current year's presentation.

</TABLE>
 
  Securities and Asset Management net revenues of $3,341 million in the
quarter ended February 28, 1998 represented an increase of 22% from the
quarter ended February 28, 1997. Securities and Asset Management net income of
$592 million in the quarter ended February 28, 1998 represented an increase of
33% from the quarter ended February 28, 1997. The increases reflected higher
levels of investment banking, asset management, distribution and
administration fees, principal transaction trading and investment revenues and
commissions, partially offset by higher incentive-based compensation and other
non-interest expenses.
 
 Investment Banking
 
  Investment banking revenues are derived from the underwriting of securities
offerings and fees from advisory services. Investment banking revenues in the
quarter ended February 28, 1998 increased 53% from the quarter ended February
28, 1997, primarily reflecting significantly higher revenues from merger and
acquisition transactions as well as higher revenues from both debt and equity
underwritings. Revenues from merger, acquisition and restructuring activities
increased to record levels, as the global market for such transactions
continued to be robust during the quarter. The high levels of transaction
activity reflected the continuing trend of consolidation and globalization
across many industry sectors, coupled with continued financial deregulation in
the U.S. and market liberalization in Europe. In the quarter ended February
28, 1998, merger and acquisition activity was diversified across many
industries, with the financial services, pharmaceuticals and technology
sectors contributing the greatest level of revenues. Advisory fees from real
estate transactions also increased
 
                                      16
<PAGE>
 
during the quarter. A stable financing environment, favorable economic
conditions and a strong real estate market, including accelerated
consolidation activity among real estate investment trusts ("REITS") and high
investor demand for the securities of public real estate companies,
contributed to the increase. Fixed income underwriting revenues also
increased, primarily attributable to higher revenues from global high yield
debt issuances. The market for these securities benefited from strong investor
demand and from the favorable market and economic conditions that existed
during much of the quarter which enabled certain non-investment grade issuers
to obtain attractive financing rates. Equity financing revenues also
increased, primarily due to a higher volume of equity offerings as compared to
the prior year's quarter.
 
 Principal Transactions
 
  Principal transaction trading revenues, which include revenues from customer
purchases and sales of securities in which the Company acts as principal and
gains and losses on securities held for resale, including derivatives,
increased 4% in the quarter ended February 28, 1998 from the quarter ended
February 28, 1997. The increase was due to higher revenues from trading in
equities, foreign exchange and commodities, partially offset by lower fixed
income trading revenues.
 
  Fixed income trading revenues declined in the quarter ended February 28,
1998 from the quarter ended February 28, 1997, primarily due to lower revenues
from trading in investment grade and securitized fixed income securities. The
market for investment grade fixed income securities was adversely affected by
the economic and market turmoil in Asia, particularly during the first months
of the quarter. These uncertain conditions prompted "a flight to quality" as
investor demand for less risky Treasury securities increased, resulting in a
widening of interest rate spreads for investment grade securities. Revenues
from trading securitized fixed income securities also decreased, as the
declining yields of U.S. Treasury securities during the quarter increased
prepayment risk and resulted in a widening of interest rate spreads. These
decreases were partially offset by higher revenues from trading fixed income
derivatives and global high yield securities.
 
  Equity trading revenues in the quarter ended February 28, 1998 increased
over the comparable prior year period. Revenues from trading in equity cash
products increased, primarily due to increased customer volume and a higher
market share in European markets benefiting from the Company's increased sales
and research coverage beginning in mid-1997. The increased activity in Europe
was primarily attributable to the strong performance of many European equity
markets during the quarter, reflecting favorable market conditions, low
interest rates and strong corporate earnings. Equity cash trading revenues
also benefited from an increase in the Company's market share in Japan. Higher
revenues from equity derivative securities also contributed to the increase in
equity trading revenues.
 
  Trading revenues from commodity products increased in the quarter ended
February 28, 1998, primarily driven by higher revenues from trading in crude
oil, refined energy products and precious and base metals. Revenues from
trading in crude oil and refined energy products were impacted by falling
prices during most of the quarter due to diminished demand for energy products
in Asia amid the economic crisis, declining tensions between the U.S. and Iraq
and growing output from certain oil producing regions, including the North
Sea. Revenues from trading in precious and base metals benefited from rising
silver prices and increased volatility in the gold market. These increases
were partially offset by lower revenues from trading in natural gas as
unseasonably warm weather in the Midwest and Northeast regions of the U.S.
caused a reduction in the demand for home heating fuel, leading to a decline
in prices.
 
  Foreign exchange trading revenues also increased in the quarter ended
February 28, 1998, and represented the second highest level of quarterly
foreign exchange trading revenues achieved by the Company. The increase was
primarily attributable to high levels of customer trading volumes and
volatility in foreign exchange markets, particularly during the first two
months of the quarter. Such conditions were primarily the result of the
difficult economic and financial conditions existing in Asia, as diminished
investor confidence caused many currencies in this region to reach record
lows. Conditions in Asia were more stable during the latter part of the
quarter, as the success of South Korean banks to reschedule their
international debt payments reduced volatility in the region.

<PAGE>
 
In addition, the U.S. dollar continued to exhibit strength against other major
currencies during the quarter, primarily due to the overall strength of the
U.S. economy.
 
  Principal transaction investment gains aggregating $72 million were
recognized in the quarter ended February 28, 1998 as compared to $56 million
in the comparable prior year quarter. Fiscal 1998's revenues were primarily
related to gains realized from the sale of the Company's remaining position in
Fort James Corporation. Net increases in the carrying values of certain
private equity investments and gains from certain venture capital investments
also contributed to the increase in principal transaction investment revenues.
 
 Commissions
 
  Commission revenues primarily arise from agency transactions in listed and
over-the-counter equity securities, and sales of mutual funds, futures,
insurance products and options. Commission revenues increased 10% in the
quarter ended February 28, 1998 from the quarter ended February 28, 1997. In
U.S. markets, the Company benefited from a high volume of customer securities
transactions. Revenues from markets in the Far East also benefited from strong
transaction volumes, coupled with an increase in the Company's market share
due to a shift in customer trading volume away from certain large Japanese
brokerage companies. In Europe, trading volumes continued to be high due to
the strong performance of many equity markets within that region.
 
 Asset Management, Distribution and Administration Fees
 
  Asset management, distribution and administration revenues include fees for
asset management services, including fund management fees which are received
for investment management, fees received for promoting and distributing mutual
funds ("12b-1 fees"), and other administrative fees and non-interest revenues
earned from correspondent clearing and custody services. Fund management fees
arise from investment management services the Company provides to registered
investment companies (the "Funds") pursuant to various contractual
arrangements. The Company receives management fees based upon each Fund's
average daily net assets. The Company receives 12b-1 fees for services it
provides in promoting and distributing certain open-ended Funds. These fees
are based on either the average daily Fund net asset balances or average daily
aggregate net Fund sales and are affected by changes in the overall level and
mix of assets under management and administration. The Company also receives
fees from investment management services provided to segregated customer
accounts pursuant to various contractual arrangements.
 
  Asset management, distribution and administration revenues increased 15% in
the quarter ended February 28, 1998 from the quarter ended February 28, 1997,
reflecting strong fund performance and favorable market conditions which
continue to attract inflows of new business. Higher fund management and 12b-1
fees, as well as increased revenues from international equity and U.S. fixed
income products resulting from inflows of client assets and market
appreciation had a favorable impact on these revenues.
 
  Customer assets under management or supervision increased to $356 billion at
February 28, 1998 from $290 billion at February 28, 1997. The increase in
assets under management or supervision reflected continued inflows of customer
assets and appreciation in the value of existing customer portfolios. Customer
assets under management or supervision included products offered primarily to
individual investors of $201 billion at February 28, 1998 and $168 billion at
February 28, 1997. Products offered primarily to institutional investors was
$155 billion at February 28, 1998 and $122 billion at February 28, 1997.
 
  Customer assets under administration in the global custody business
increased to $402 billion at February 28, 1998 from $152 billion at February
28, 1997. Approximately $217 billion of this increase was attributable to the
Company's acquisition of the institutional global custody business of Barclays
Bank PLC ("Barclays") on April 3, 1997, and approximately $97 billion of these
assets remain subject to current clients of Barclays agreeing to become
clients of the Company. Appreciation in the value of customer portfolios and
additional assets placed
 
                                      18
<PAGE>
 
under custody with the Company, including new customer accounts and additional
assets from existing customers, also contributed to the growth in assets under
administration.
 
 Net Interest
 
  Interest and dividend revenues and expense are a function of the level and
mix of total assets and liabilities, including financial instruments owned,
reverse repurchase and repurchase agreements and customer margin loans, and
the prevailing level, term structure and volatility of interest rates.
Interest and dividend revenues and expense should be viewed in the broader
context of principal trading and investment banking results. Decisions
relating to principal transactions in securities are based on an overall
review of aggregate revenues and costs associated with each transaction or
series of transactions. This review includes an assessment of the potential
gain or loss associated with a trade, the interest income or expense
associated with financing or hedging the Company's positions, and potential
underwriting, commission or other revenues associated with related primary or
secondary market sales. Net interest revenues increased 69% in the quarter
ended February 28, 1998 from the quarter ended February 28, 1997. The increase
was primarily attributable to higher levels of revenues from net interest
earning assets, including financial instruments owned and customer margin
receivable balances. Higher levels of securities lending transactions also had
a positive affect on net interest and dividend revenues. These increases were
partially offset by higher interest expense associated with a higher level of
interest bearing liabilities, including long-term debt.
 
 Non-Interest Expenses
 
  Total non-interest expenses increased 18% in the quarter ended February 28,
1998 from the quarter ended February 28, 1997. Within that category,
compensation and benefits expense increased 21%, principally reflecting
increased incentive compensation based on higher revenues and earnings.
Excluding compensation and benefits expense, non-interest expenses increased
12%. Occupancy and equipment expenses increased 8%, primarily due to increased
office space in Hong Kong and higher occupancy costs in London and certain
other office locations. Brokerage, clearing and exchange fees increased 22%,
primarily related to the acquisition of the institutional global custody
business of Barclays, as well as a higher level of securities trading volume
during the quarter. Information processing and communications expenses
increased 4%, primarily due to the impact of increased rates for certain data
services as well as other information systems costs. Marketing and business
development expenses increased 16%, reflecting increased travel and
entertainment costs associated with the continued high levels of activity in
the global financial markets as the Company continues to develop new business.
Professional services expenses increased 40%, primarily reflecting higher
consulting costs associated with information technology initiatives and the
Company's increased global business activities. Higher temporary staff and
employment fees also contributed to the increase.

</TABLE>
 
  Credit and Transaction Services net income of $99 million in the quarter
ended February 28, 1998 represented a decrease of 21% from the quarter ended
February 28, 1997, as increased credit losses and a lower yield on general
purpose credit card loans were partially offset by a decrease in non-interest
expenses.
 
  As a result of enhancements made to certain of the Company's accounting
systems in the fourth quarter of fiscal 1997, the Company began recording
charged off cardmember fees directly against the income statement line items
to which they were originally recorded (merchant and cardmember fees and
interest revenue). Prior to the enhancements, these fees were charged off
against interest revenue. While this change has no impact on net revenues, the
Company believes that the revised presentation better reflects the manner in
which charge-offs affect the Credit and Transaction Services statements of
income. However, since prior periods have not been restated to reflect this
change, the comparability of merchant and cardmember fees and interest
revenues between the quarter ended February 28, 1998 and the quarter ended
February 28, 1997 has been affected. Accordingly, the following sections will
also discuss the changes in these income statement categories excluding the
impact of this reclassification.
 
 Non-Interest Revenues
 
  Total non-interest revenues decreased 5% in the quarter ended February 28,
1998 from the quarter ended February 28, 1997. Excluding the effect of the
reclassification of charged off cardmember fees discussed above, non-interest
revenue would have remained level.
 
                                      20
<PAGE>
 
  Merchant and cardmember fees include revenues from fees charged to merchants
on credit card sales, late payment fees, overlimit fees, insurance fees, cash
advance fees, the administration of credit card programs and transaction
processing services. Merchant and cardmember fees decreased 2% in the quarter
ended February 28, 1998 from the comparable prior year period. Excluding the
effect of the reclassification of charged off cardmember fees discussed above,
merchant and cardmember fees increased 4% in the quarter ended February 28,
1998. Merchant and cardmember fees increased due to a higher level of general
purpose credit card transaction volume. Higher occurrences of overlimit and
late payment fees also contributed to the increase.
 
  Servicing fees are revenues derived from consumer loans that have been sold
to investors through asset securitizations. Cash flows from the interest yield
and cardmember fees generated by securitized loans are used to pay investors
in these loans a predetermined fixed or floating rate of return on their
investment, to reimburse investors for losses of principal through charged off
loans and to pay the Company a fee for servicing the loans. Any excess cash
flows remaining are paid to the Company. The servicing fees and excess net
cash flows paid to the Company are reported as servicing fees in the condensed
consolidated statements of income. The sale of consumer loans through asset
securitizations therefore has the effect of converting portions of net credit
income and fee income to servicing fees.
 
  The table below presents the components of servicing fees (dollars in
millions):

  Servicing fees decreased 15% in the quarter ended February 28, 1998 from the
quarter ended February 28, 1997, as revenues associated with a higher level of
consumer loans were more than offset by an increase in the provision for
consumer loan losses resulting from a higher charge off rate.
 
  Commission revenues arise from customer securities transactions associated
with Discover Brokerage Direct, Inc. ("DBD"), the Company's provider of
electronic brokerage services acquired in January 1997. The increase in
commission revenues in the quarter ended February 28, 1998 reflects a full
quarter's results for DBD, as well as a significantly higher level of customer
transaction volume.
 
 Net Interest Income
 
  Net interest income is equal to the difference between interest revenue
derived from Credit and Transaction Services consumer loans and short-term
investment assets and interest expense incurred to finance those assets.
Credit and Transaction Services assets, consisting primarily of consumer
loans, earn interest revenue at both fixed rates and market-indexed variable
rates. The Company incurs interest expense at fixed and floating rates.
Interest expense also includes the effects of interest rate contracts entered
into by the Company as part of its interest rate risk management program. This
program is designed to reduce the volatility of earnings resulting from
changes in interest rates and is accomplished primarily through matched
financing, which entails matching the repricing schedules of consumer loans
and related financing. Net interest income increased 1% in the quarter ended
February 28, 1998 from the quarter ended February 28, 1997. Excluding the
effect of the reclassification of charged off cardmember fees discussed above,
net interest income would have decreased 4% from the comparable prior year
period. The decrease was predominately due to higher net charge-offs, a lower
yield on general purpose credit card loans and an increase in the Company's
cost of funds, partially offset by a higher level of general purpose credit
card loans. The lower yield on general purpose credit card loans was primarily
due to a larger number of cardmembers taking advantage of lower promotional
rates.

 Provision for Consumer Loan Losses
 
  The provision for consumer loan losses is the amount necessary to establish
the allowance for loan losses at a level the Company believes is adequate to
absorb estimated losses in its consumer loan portfolio at the balance sheet
date. The Company's allowance for loan losses is regularly evaluated by
management for adequacy on a portfolio-by-portfolio basis and was $905 million
and $828 million at February 28, 1998 and 1997. The provision for consumer
loan losses, which is affected by net charge-offs, loan volume and changes in
the amount of consumer loans estimated to be uncollectable, increased 7% in
the quarter ended February 28, 1998 from the quarter ended February 28, 1997
due to an increase in net charge-offs. The increase in net charge-offs was due
to increases in the rate of charge-offs and, to a lesser extent, higher
average levels of consumer loans. Net charge-offs as a percentage of average
consumer loans outstanding increased to 7.51% in the quarter ended February
28, 1998 from 6.89% in the comparable period of 1997. The Company expects to
experience a higher net charge-
 
                                      23
<PAGE>
 
off rate for full fiscal year 1998 as compared to fiscal 1997. In fiscal 1997,
the Company intensified steps to reduce the impact of increased net charge-
offs and continues to implement measures designed to improve the credit
quality of both new and existing credit card accounts. The Company's
expectations about future charge-off rates and credit quality are subject to
uncertainties that could cause actual results to differ materially from what
has been discussed above. Factors that influence the level and direction of
consumer loan delinquencies and charge-offs include changes in consumer
spending and payment behaviors, bankruptcy trends, the seasoning of the
Company's loan portfolio, interest rate movements and their impact on consumer
behavior, and the rate and magnitude of changes in the Company's consumer loan
portfolio, including the overall mix of accounts, products and loan balances
within the portfolio.
 
  Consumer loans are considered delinquent when interest or principal payments
become 30 days past due. Consumer loans are charged off when they become 180
days past due, except in the case of bankruptcies and fraudulent transactions,
where loans are charged off earlier. Loan delinquencies and charge-offs are
primarily affected by changes in economic conditions and may vary throughout
the year due to seasonal consumer spending and payment behaviors.
 
  From time to time, the Company has offered and may continue to offer
cardmembers with accounts in good standing the opportunity to skip the minimum
monthly payment, while continuing to accrue periodic finance charges, without
being considered to be past due ("skip-a-payment"). The comparison of
delinquency rates at any particular point in time may be affected depending on
the timing of the skip-a-payment program. The delinquency rates for consumer
loans 90-179 days past due at February 28, 1998 and 30-89 days past due at
November 30, 1997 were favorably impacted by a skip-a-payment offer made in
October 1997.
 
  The following table presents delinquency and net charge-off rates with
supplemental managed loan information:

 Non-Interest Expenses
 
  Non-interest expenses decreased 2% in the quarter ended February 28, 1998
from the quarter ended February 28, 1997.
 
  Compensation and benefits expense increased 5% in the quarter ended February
28, 1998 from the comparable period of 1997 due to an increase in the number
of employees, including those related to the Company's acquisition of DBD in
January 1997. Brokerage, clearing and exchange fees relate to the trading
activity associated with DBD. The increase in the quarter ended February 28,
1998 reflects a full quarter's results for DBD, coupled with significantly
higher customer transaction volume. Information processing and communications
expense decreased 6%, primarily due to lower transaction processing costs, an
adjustment resulting from the sale of the Company's indirect interest in one
of the Company's transaction processing vendors and favorable repricing of
certain data communication contracts. Marketing and business development
 
                                      24
<PAGE>
 
expense decreased 5% as the result of lower advertising and promotional
expenses, partially offset by an increase in Cardmember rewards expense. Lower
advertising and promotional expense during the quarter was primarily
associated with the Company's plan to discontinue its BRAVO credit card brand.
Cardmember rewards expense includes the Cashback Bonus(R) award, pursuant to
which the Company annually pays Discover(R) Cardmembers and Private Issue
Cardmembers electing this feature a percentage of their purchase amounts.
Commencing March 1, 1998, the terms of the Private Issue Cashback Bonus were
amended by limiting the maximum bonus amount to $500 and by increasing the
amount of purchases required to receive this bonus amount. The Company
believes that its Cardmember rewards expense in future periods will not be
materially impacted by these changes. Professional services expenses increased
28%, primarily due to higher consulting costs. Other expenses decreased 20%
due to a continuing decrease in fraud losses and reductions in other general
business expenses.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's total assets increased from $302.3 billion at November 30,
1997 to $345.5 billion at February 28, 1998, reflecting growth in financial
instruments owned, resale agreements and securities borrowed, as well as
additional assets recognized due to the adoption of SFAS No. 127. A
substantial portion of the Company's total assets consists of highly liquid
marketable securities and short-term receivables arising principally from
securities transactions. The highly liquid nature of these assets provides the
Company with flexibility in financing and managing its business.
 
  The Company's senior management establishes the overall funding and capital
policies of the Company, reviews the Company's performance relative to these
policies, monitors the availability of sources of financing, reviews the
foreign exchange risk of the Company and oversees the liquidity and interest
rate sensitivity of the Company's asset and liability position. The primary
goal of the Company's funding and liquidity activities is to ensure adequate
financing over a wide range of potential credit ratings and market
environments.
 
  The Company views return on equity to be an important measure of its
performance, both in the context of the particular business environment in
which the Company is operating and its peer group's results. In this regard,
the Company actively manages its consolidated capital position based upon,
among other things, business opportunities, capital availability and rates of
return together with internal capital policies, regulatory requirements and
rating agency guidelines and therefore may, in the future, expand or contract
its capital base to address the changing needs of its businesses. The Company
returns internally generated equity capital which is in excess of the needs of
its businesses to its shareholders through common stock repurchases and
dividends.
 
  The Company funds its balance sheet on a global basis. The Company's funding
for its Securities and Asset Management business is raised through diverse
sources. These include the Company's capital, including equity and long-term
debt; repurchase agreements; U.S., Canadian, Euro, French and Japanese
commercial paper; letters of credit; unsecured bond borrows; German
Schuldschein loans; securities lending; buy/sell agreements; municipal re-
investments; master notes; and committed and uncommitted lines of credit.
Repurchase transactions, securities lending and a portion of the Company's
bank borrowings are made on a collateralized basis and therefore provide a
more stable source of funding than short-term unsecured borrowings.
 
  The funding sources utilized for the Company's Credit and Transaction
Services business include the Company's capital, including equity and long-
term debt; asset securitizations; commercial paper; deposits; asset-backed
commercial paper; Fed Funds; and short-term bank notes. The Company sells
consumer loans through asset securitizations using several transaction
structures. Riverwoods Funding Corporation ("RFC"), an entity included in the
condensed consolidated financial statements of the Company, issues asset-
backed commercial paper.
 
 
                                      25
<PAGE>
 
  The Company's bank subsidiaries solicit deposits from consumers, purchase
federal funds and issue short-term bank notes. Interest bearing deposits are
classified by type as savings, brokered and other time deposits. Savings
deposits consist primarily of money market deposits and certificate of deposit
accounts sold directly to cardmembers and savings deposits from individual
securities clients. Brokered deposits consist primarily of certificates of
deposits issued by the Company's bank subsidiaries. Other time deposits
include institutional certificates of deposits. The Company, through Greenwood
Trust Company, an indirect subsidiary of the Company, sells notes under a
short-term bank note program.
 
  The Company maintains borrowing relationships with a broad range of banks,
financial institutions, counterparties and others from which it draws funds in
a variety of currencies. The volume of the Company's borrowings generally
fluctuates in response to changes in the amount of repurchase transactions
outstanding, the level of the Company's securities inventories and consumer
loans receivable, and overall market conditions. Availability and cost of
financing to the Company can vary depending upon market conditions, the volume
of certain trading activities, the Company's credit ratings and the overall
availability of credit.
 
  The Company's reliance on external sources to finance a significant portion
of its day-to-day operations makes access to global sources of financing
important. The cost and availability of unsecured financing generally are
dependent on the Company's short-term and long-term debt ratings. In addition,
the Company's debt ratings have a significant impact on certain trading
revenues, particularly in those businesses where longer term counterparty
performance is critical, such as over-the-counter derivative transactions.
 
  As of March 31, 1998, the Company's credit ratings were as follows:

  As the Company continues its global expansion and as revenues are
increasingly derived from various currencies, foreign currency management is a
key element of the Company's financial policies. The Company benefits from
operating in several different currencies because weakness in any particular
currency is often offset by strength in another currency. The Company closely
monitors its exposure to fluctuations in currencies and, where cost-justified,
adopts strategies to reduce the impact of these fluctuations on the Company's
financial performance. These strategies include engaging in various hedging
activities to manage income and cash flows denominated in foreign currencies
and using foreign currency borrowings, when appropriate, to finance
investments outside the U.S.
 
  During the quarter ended February 28, 1998, the Company issued senior notes
aggregating $2,922 million, including non-U.S. dollar currency notes
aggregating $589 million, primarily pursuant to its public debt shelf
registration statements. These notes have maturities from 1998 to 2024 and a
weighted average coupon interest rate of 5.4% at February 28, 1998; the
Company has entered into certain transactions to obtain floating interest
rates based primarily on short-term LIBOR trading levels. At February 28,
1998, the aggregate outstanding principal amount of the Company's Senior
Indebtedness (as defined in the Company's public debt shelf registration
statements) was approximately $44.8 billion.
 
  On February 12, 1998, the Company's Board of Directors authorized the
Company to purchase, subject to market conditions and certain other factors,
up to $3 billion of the Company's common stock. During the quarter ended
February 28, 1998 the Company purchased $27 million of its common stock.
Subsequent to February 28, 1998 and through March 31, 1998, the Company
purchased an additional $349 million of its common stock.
 
                                      26
<PAGE>
 
  On February 25, 1998, the Company's shelf registration statement for an
additional $8 billion of debt securities, warrants, preferred stock or
purchase contracts or any combination thereof in the form of units, became
effective.
 
  On March 5, 1998, MSDW Capital Trust I, a Delaware statutory business trust
(the "Capital Trust"), all of the common securities of which are owned by the
Company, issued $400 million of 7.10% Capital Securities (the "Capital
Securities") that are guaranteed by the Company. The Capital Trust issued the
Capital Securities and invested the proceeds in 7.10% Junior Subordinated
Deferrable Interest Debentures due February 28, 2038 issued by the Company.
 
  The Company maintains a senior revolving credit agreement with a group of
banks to support general liquidity needs, including the issuance of commercial
paper (the "MSDW Facility"). Under the terms of the MSDW Facility, the banks
are committed to provide up to $6.0 billion. The MSDW Facility contains
restrictive covenants which require, among other things, that the Company
maintain shareholders' equity of at least $8.3 billion at all times. The
Company believes that the covenant restrictions will not impair the Company's
ability to pay its current level of dividends. At February 28, 1998, no
borrowings were outstanding under the MSDW Facility.
 
  The Company maintains a master collateral facility that enables Morgan
Stanley & Co. Incorporated ("MS&Co."), one of the Company's U.S. broker-dealer
subsidiaries, to pledge certain collateral to secure loan arrangements,
letters of credit and other financial accommodations (the "MS&Co. Facility").
As part of the MS&Co. Facility, MS&Co. also maintains a secured committed
credit agreement with a group of banks that are parties to the master
collateral facility under which such banks are committed to provide up to
$1.875 billion. At February 28, 1998, no borrowings were outstanding under the
MS&Co. Facility.
 
  The Company also maintains a revolving committed financing facility that
enables Morgan Stanley & Co. International Limited ("MSIL"), the Company's
U.K. broker-dealer subsidiary, to secure committed funding from a syndicate of
banks by providing a broad range of collateral under repurchase agreements
(the "MSIL Facility"). Such banks are committed to provide up to an aggregate
of $1.85 billion available in 12 major currencies. At February 28, 1998, no
borrowings were outstanding under the MSIL Facility.
 
  RFC also maintains a $2.55 billion senior bank credit facility which
supports the issuance of asset-backed commercial paper. RFC has never borrowed
from its senior bank credit facility.
 
  The Company anticipates that it will utilize the MSDW Facility, the MS&Co.
Facility or the MSIL Facility for short-term funding from time to time.
 
  At February 28, 1998, certain assets of the Company, such as real property,
equipment and leasehold improvements of $1.7 billion, and goodwill and other
intangible assets of $1.3 billion, were illiquid. In addition, certain equity
investments made in connection with the Company's private equity and other
principal investment activities, high-yield debt securities, emerging market
debt, and certain collateralized mortgage obligations and mortgage-related
loan products are not highly liquid. In connection with its private equity and
other principal investment activities, the Company has equity investments
(directly or indirectly through funds managed by the Company) in privately and
publicly held companies. At February 28, 1998, the aggregate carrying value of
the Company's equity investments in privately held companies (including direct
investments and partnership interests) was $135 million, and its aggregate
investment in publicly held companies was $321 million.
 
  The Company acts as an underwriter of and as a market-maker in mortgage-
backed pass-through securities, collateralized mortgage obligations and
related instruments, and as a market-maker in commercial, residential
 
                                      27
<PAGE>
 
and real estate loan products. In this capacity, the Company takes positions
in market segments where liquidity can vary greatly from time to time. The
carrying value of the portion of the Company's mortgage-related portfolio at
February 28, 1998 traded in markets that the Company believed were
experiencing lower levels of liquidity than traditional mortgage-backed pass-
through securities approximated $2,790 million.
 
  In addition, at February 28, 1998, the aggregate value of high-yield debt
securities and emerging market loans and securitized instruments held in
inventory was $2,074 million (a substantial portion of which was subordinated
debt) with not more than 6%, 21% and 9% of all such securities, loans and
instruments attributable to any one issuer, industry or geographic region,
respectively. Non-investment grade securities generally involve greater risk
than investment grade securities due to the lower credit ratings of the
issuers, which typically have relatively high levels of indebtedness and are,
therefore, more sensitive to adverse economic conditions. In addition, the
market for non-investment grade securities and emerging market loans and
securitized instruments has been, and may in the future be, characterized by
periods of volatility and illiquidity. The Company has credit and other risk
policies and procedures to control total inventory positions and risk
concentrations for non-investment grade securities and emerging market loans
and securitized instruments.
 
  The Company may, from time to time, also provide financing or financing
commitments to companies in connection with its investment banking and private
equity activities. The Company may provide extensions of credit to leveraged
companies in the form of senior or subordinated debt, as well as bridge
financing on a selective basis (which may be in connection with the Company's
commitment to the Morgan Stanley Bridge Fund, LLC). At February 28, 1998, the
Company had three commitments to provide an aggregate of $678 million and had
one loan in the amount of $342 million outstanding primarily in connection
with its securitized debt and high-yield underwriting activities. Subsequent
to February 28, 1998, the Company's aggregate commitments increased to $1,336
million, and the $342 million outstanding loan was repaid.
 
  The Company also engages in senior lending activities, including
origination, syndication and trading of senior secured loans of non-investment
grade companies. Such companies are more sensitive to adverse economic
conditions than investment grade issuers, but the loans are generally made on
a secured basis and are senior to any non-investment grade securities of these
issuers that trade in the capital markets. At February 28, 1998, the aggregate
value of senior secured loans and positions held by the Company was $522
million, and aggregate senior secured loan commitments were $318 million.
Subsequent to February 28, 1998, the Company entered into three additional
senior secured loan positions having an aggregate value of $193 million.
 
  At February 28, 1998, financial instruments owned by the Company included
derivative products (generally in the form of futures, forwards, swaps, caps,
collars, floors, swap options and similar instruments which derive their value
from underlying interest rates, foreign exchange rates or commodity or equity
instruments and indices) related to financial instruments and commodities with
an aggregate net replacement cost of $18.0 billion. The net replacement cost
of all derivative products in a gain position represents the Company's maximum
exposure to derivatives related credit risk. Derivative products may have both
on- and off-balance sheet risk implications, depending on the nature of the
contract. It should be noted, however, that in many cases derivatives serve to
reduce, rather than increase, the Company's exposure to losses from market,
credit and other risks. The risks associated with the Company's derivative
activities, including market and credit risks, are managed on an integrated
basis with associated cash instruments in a manner consistent with the
Company's overall risk management policies and procedures. The Company manages
its credit exposure to derivative products through various means, which
include reviewing counterparty financial soundness periodically; entering into
master netting agreements and collateral arrangements with counterparties in
appropriate circumstances; and limiting the duration of exposure.
 
 Year 2000 and EMU
 
  Many of the world's computer systems currently record years in a two-digit
format. Such computer systems will be unable to properly interpret dates
beyond the year 1999, which could lead to business disruptions in the U.S. and
internationally (the "Year 2000" issue).
 
                                      28
<PAGE>
 
  The Company continues to review its computer systems and programs in order
to prepare for Year 2000 compliance. Based upon current information, the
Company believes that its Year 2000 expenditures for fiscal 1998 and through
the project's completion will be approximately $125 million. Costs incurred
relating to this project are being expensed by the Company during the period
in which they are incurred. The Company's expectations about future costs
associated with the Year 2000 issue are subject to uncertainties that could
cause actual results to differ materially from what has been discussed above
(see "Management's Discussion and Analysis of Financial Condition and Results
of Operations" included in the Company's Annual Report on Form 10-K for the
fiscal year ended November 30, 1997.)
 
  Modifications to the Company's computer systems and programs are also being
made in order to prepare for the upcoming EMU. The EMU, which will ultimately
result in the replacement of certain European currencies with the "Euro," will
primarily impact the Company's Securities and Asset Management business. Costs
associated with the modifications necessary to prepare for the EMU are also
being expensed by the Company during the period in which they are incurred.

PART II. OTHER INFORMATION
 
ITEM 1. LEGAL PROCEEDINGS.
 
  The following developments have occurred with respect to certain matters
previously reported in the Company's Annual Report on Form 10-K for the fiscal
year ended November 30, 1997 (the "Form 10-K").
 
  In re Sumitomo Copper Litigation. On March 13, 1998, plaintiffs filed a
motion for a class certification. Also on March 13, 1998, another purported
class action complaint, captioned Khazzam, et al. v. Sumitomo Corporation, et
al., was filed in the United States District Court for the Southern District
of New York. This action is substantially similar to the class action
described in the Form 10-K, asserting the same claims against the same
defendants (excluding the Winchester defendants) and seeking the same relief.
The complaint asserts a manipulation claim under the Commodity Exchange Act
against all of the defendants and a RICO claim against certain of the
defendants other than MS&Co. In addition, on April 3, 1998, a first amended
class action complaint, captioned Polansky, et al. v. Sumitomo Corporation of
America, et al., was filed in the United States District Court for the
Southern District of New York. This action is substantially similar to the
class action described in the Form 10-K, asserting the same claims against the
same defendants (excluding the Winchester defendants) and seeking the same
relief. The plaintiff class purportedly consists of all persons who purchased
put options or sold call options on copper futures contracts on the Comex
Division of the New York Mercantile Exchange between May 9, 1994 and June 15,
1996.
 
  County of Orange and Moorlach v. Morgan Stanley & Co., Inc. The hearing on
the motion to dismiss all of the ultra vires claims has been continued to June
1, 1998.
 
  Global Opportunity Fund Litigation. On March 11, 1998, The Growth Fund,
which was a sub fund of The Global Opportunity Fund (the "Fund"), and 14
investors in The Growth Fund (12 of whom are also plaintiffs in the Luxembourg
litigation against Morgan Stanley Bank Luxembourg, S.A. ("MSBL")) brought an
action against Morgan Stanley International & Co. Limited ("MSIL") in the
Supreme Court of the State of New York, County of New York. The complaint
asserts purported claims for fraud, aiding and abetting fraud, negligent
misrepresentation and violation of a duty of good faith and fair dealing and
seeks compensatory damages of approximately $7.25 million, punitive damages,
interest and costs, expenses and attorneys' fees. Plaintiffs assert that MSIL
induced them to enter into margin loans for the purpose of investing in
another sub fund of the Fund at a time when MSIL allegedly knew that MSBL was
not complying with its purported duty to monitor the Fund and the Fund's
manager was fraudulently inflating the value of certain of its assets, which
resulted in the investors' reliance on false net asset values in making and
continuing their investments in the Fund.
 
ITEM 5. OTHER INFORMATION.
 
Revised Earnings Per Share Amounts in Accordance with FASB Statement 128.
 
  In February 1997, the FASB issued Statement of Financial Accounting
Standards ("SFAS") No. 128, "Earnings per Share" ("EPS"), effective for
periods ending after December 15, 1997, with restatement required for all
prior periods. SFAS No. 128 replaces the previous EPS categories of primary
and fully diluted with "basic EPS," which reflects no dilution from common
stock equivalents, and "diluted EPS," which reflects dilution from common
stock equivalents and other dilutive securities based on the average price per
share of the Company's common stock during the period. Therefore, the Company
is filing herewith as Exhibit 99 restated selected financial data for the last
five fiscal years, restated consolidated statements of income data for the
last three years, restated quarterly results data (unaudited) for the last two
fiscal years, and the computation of basic and diluted earnings per share for
the last three fiscal years ("Statement 128 Data").

                  MORGAN STANLEY, DEAN WITTER, DISCOVER & CO.

                        Pursuant to Section 242 of the 
                          General Corporation Law of
                             the State of Delaware

        Morgan Stanley, Dean Witter, Discover & Co. (the "Corporation"), a 
corporation organized and existing under and by virtue of the General 
Corporation Law of the State of Delaware, does hereby certify that:

        FIRST:     The Board of Directors of the Corporation, by unanimous

such business shall be conducted at a special meeting of stockholders as shall
have been brought before the meeting pursuant to the Corporation's notice of
meeting. Any previously scheduled meeting of the stockholders may be postponed,

may be made at an annual meeting of stockholders (A) pursuant to the
Corporation's notice of meeting delivered pursuant to Section 2.04 of these
Amended and Restated Bylaws, (B) by or at the direction of the Board of
Directors or (C) by any stockholder of the Corporation who is entitled to vote

<PAGE>
 
     (ii) For nominations or other business to be properly brought before an
annual meeting by a stockholder pursuant to clause (C) of paragraph (a) (i) of
this Bylaw, the stockholder must have given timely notice thereof in writing to
the Secretary of the Corporation and, in the case of business other than
nominations, such other business must otherwise be a proper matter for
stockholder action.  To be timely, a stockholder's notice shall be delivered to
the Secretary at the principal executive offices of the Corporation not less
than ninety days nor more than one hundred and twenty days prior to the first
anniversary of the preceding year's annual meeting; provided however, that with
respect to the annual meeting to be held in 1998, the anniversary date shall be
deemed to be April 2, 1998; provided further, that in the event that the date of
the annual meeting is advanced by more than thirty days, or delayed by more than
ninety days, from such anniversary date, notice by the stockholder to be timely
must be so delivered not earlier than the one hundred and twentieth day prior to
such annual meeting and not later than the close of business on the later of the
ninetieth day prior to such annual meeting or the tenth day following the day on
which public announcement of the date of such meeting is first made.  In no
event shall the public announcement of an adjournment or postponement of an
annual meeting commence a new time period for the giving of a stockholder's
notice as described in this Section 2.07(a). Such stockholder's notice shall set
forth (A) as to each person whom the stockholder proposes to nominate for
election or reelection as a director all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
directors in an election contest, or is other-wise required, in each case
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended
(the "Exchange Act") and Rule 14a-11 thereunder, including such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director if elected; (B) as to any other business that the stockholder proposes
to bring before the meeting, a brief description of the business desired to be
brought before the meeting, the reasons for conducting such business at the
meeting and any material interest in such business of such stockholder and the
beneficial owner, if any, on whose behalf the proposal is made; and (C) as to
the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made (1) the name and address of such
stockholder, as they appear on the Corporation's books, and of such beneficial
owner and (2) the class and number of shares of the Corporation which are owned
beneficially and of record by such stockholder and such beneficial owner.

     (iii) Notwithstanding anything in the second sentence of clause (ii) of
this Section 2.07(a) to the contrary, in the event that the number of directors
to be elected to the Board of Directors of the Corporation is increased and
there is no public announcement naming all of the nominees for director or
specifying the size of the increased Board of Directors made by the Corporation
at least one hundred days prior to the first anniversary of the preceding year's
annual meeting, a stockholder's notice required by this Bylaw shall also be
considered timely, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary at the
principal executive offices of the Corporation not later than the close of
business on the tenth day following the day on which such public announcement is
first made by the Corporation.

     (b) Special Meetings of Stockholders.

     Only such business shall be conducted at a special meeting of stockholders
as shall have been brought before the meeting pursuant to the Corporation's
notice of meeting pursuant to Section 2.04 of these Amended and Restated Bylaws.
Nominations of persons for election to the Board of Directors may be made at a
special meeting of stockholders at which directors are to be elected pursuant to
the Corporation's notice of meeting (i) by or at the direction of the Board of
Directors or (ii) by any stockholder of the Corporation who is entitled to vote
at the meeting, who complies with the notice procedures set forth in this Bylaw
and who is a stockholder of record at the time such notice is delivered to the
Secretary of the Corporation.  In the event the Corporation calls a special
meeting of stockholders for the purpose of electing one or more directors to the
Board of Directors, any such stockholder may nominate such number of persons for
election to such position(s) as are specified in the Corporation's Notice of
Meeting, if the stockholder's notice as required by clause (ii) of Section
2.07(a) of these Amended and Restated Bylaws shall be delivered to the Secretary
at the principal executive offices of the Corporation not earlier than the one
hundred and twentieth day prior to such special meeting and not later than the
close of business on the later of the ninetieth day prior to such special
meeting or the tenth day following the day on which public announcement is first
made of the date of the special meeting and of the nominees proposed by the
Board of Directors to be elected at such meeting.  In no event shall the public
announcement of an adjournment or postponement of a special meeting commence a
new time period for the giving of a stockholder's notice as described above.

     (c) General

     (i) Only persons who are nominated in accordance with the procedures set
forth in this Bylaw shall be eligible to be elected as directors at a meeting of
stockholders and only such business shall be conducted at a meeting of
stockholders as shall have been brought before the meeting in accordance with
the procedures set forth in this Bylaw.  Except as otherwise provided by law,
the Amended and Restated Certificate of Incorporation or these Amended and
Restated Bylaws, the Chairman of the Board shall have the power and duty to
determine whether a nomination or any business proposed to be brought before the
meeting was made in accordance with the procedures set forth in this Bylaw and,
if any proposed nomination or business is not in compliance with this Bylaw, to
declare that such defective proposal or nomination shall be disregarded.

     (ii) For purposes of this Bylaw, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable national news service or in a document publicly filed by the
Corporation with the Securities and Exchange Commission pursuant to Section 13,
14 or 15(d) of the Exchange Act.

     (iii) Notwithstanding the foregoing provisions of this Bylaw, a stockholder
shall also comply with all applicable requirements of the Exchange Act and the
rules and regulations thereunder with respect to the matters set forth in this
Bylaw.  Nothing in this Bylaw shall be deemed to affect any rights of
stockholders to request inclusion of proposals in the Corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act.

     SECTION 2.08.  Procedure For Election of Directors; Voting.  The election
of directors submitted to stockholders at any meeting shall be decided by a
plurality of the votes cast thereon, except as otherwise set forth in the
Amended and Restated Certificate of Incorporation with respect to the right of
the holders of any series of Preferred Stock or any other series or class of
stock to elect additional directors under specified circumstances.  Except as
otherwise provided by law, the Amended and Restated Certificate of Incorporation
or these Amended and Restated Bylaws, all matters other than the election of
directors submitted to the stockholders at any meeting shall be decided by the
affirmative vote of a majority of the voting power of the shares present in
person or represented by proxy at the meeting and entitled to vote thereon, and
where a separate vote by class is required, a majority of the voting power of
the shares of that class present in person or represented by proxy at the
meeting and entitled to vote thereon.

     The vote on any matter, including the election of directors, shall be by
written ballot.  Each ballot shall be signed by the stockholder voting, or by
such stockholder's proxy, and shall state the number of shares voted.

     SECTION 2.09.  Inspectors of Elections; Opening and Closing the Polls.

     (a)  The Board of Directors by resolution shall appoint one or more
inspectors, which inspector or inspectors may not be directors, officers or
employees of the Corporation, to act at the meeting and make a written report
thereof.  One or more persons may be designated as alternate inspectors to
replace any inspector who fails to act.  If no inspector or alternate has been
appointed to act, or if all inspectors or alternates who have been appointed are
unable to act, at a meeting of stockholders, the Chairman of the Board shall
appoint one or more inspectors to act at the meeting.  Each inspector, before
discharging his or her duties, shall take and sign an oath faithfully to execute
the duties of inspector with strict impartiality and according to the best of
his or her ability.  The inspectors shall have the duties prescribed by the
General Corporation Law of the State of Delaware.

     (b)  The Chairman of the Board shall fix and announce at the meeting the
date and time of the opening and the closing of the polls for each matter upon
which the stockholders will vote at the meeting.

     SECTION 3.01.  General Powers.  The business and affairs of the Corporation
shall be managed by or under the direction of its Board of Directors.  In
addition to the powers and authorities by these Amended and Restated Bylaws
expressly conferred upon them, the Board of Directors may exercise all such
powers of the Corporation and do all such lawful acts and things as are not by
law or by the Amended and Restated Certificate of Incorporation or by these
Amended and Restated Bylaws required to be exercised or done by the
stockholders.

     SECTION 3.02.  Number, Tenure and Qualifications. Subject to Section 3.12
of these Amended and Restated Bylaws and to the rights of the holders of any
series of Preferred Stock, or any other series or class of stock as set forth in
the Amended and Restated Certificate of Incorporation, to elect directors under
specified circumstances, the number of directors shall be fixed from time to
time exclusively pursuant to a resolution adopted by the Board of Directors, but
shall consist of not less than three nor more than fourteen directors.  However,
no decrease in the number of directors constituting the Board of Directors shall
shorten the term of any incumbent director.  The directors, other than those who
may be elected by the holders of any series of Preferred Stock, or any other
series or class of stock as set forth in the Amended and Restated Certificate of
Incorporation, shall be divided into such classes and hold office for such terms
as set forth in, and may be removed only in accordance with, the Amended and
Restated Certificate of Incorporation.

within 60 days after the date such director is first elected to the Board of
Directors.

     SECTION 3.03.  Regular Meetings.  A regular meeting of the Board of
Directors shall be held without other notice than this Bylaw immediately after,
and at the same place as, each annual meeting of stockholders.  The Board of
Directors may, by resolution, provide the time and place for the holding of
additional regular meetings without other notice than such resolution.  Unless
otherwise determined by the Board of Directors, the Secretary of the Corporation
shall act as secretary at all regular meetings of the Board of Directors and in
the Secretary's absence a temporary secretary shall be appointed by the chairman
of the meeting.

     SECTION 3.04.  Special Meetings.  Special meetings of the Board of
Directors shall be called at the request of the Chairman of the Board and the
President, acting together, or a majority of the Board of Directors.  The person
or persons authorized to call special meetings of the Board of Directors may fix

each director at his business or residence not later than three days before the
day on which such meeting is to be held or shall be sent to either of such
places by telegraph or facsimile or other electronic transmission, or be
communicated to each director personally or by telephone, not later than the day
before such day of meeting.  Neither the business to be transacted at, nor the
purpose of, any regular or special meeting of the Board of Directors need be
specified in the notice of such meeting, except for amendments to these Amended
and Restated Bylaws as provided pursuant to Section 8.01 hereof.  A meeting may
be held at any time without notice if all the directors are present (except as
otherwise provided by law) or if those present waive notice of the meeting in
accordance with Section 6.04 hereof, either before or after such meeting.

     SECTION 3.06.  Action Without Meeting.  Any action required or permitted to
be taken at any meeting of the Board of Directors or any committee thereof may
be taken without a meeting if a written consent thereto is signed by all members
of the Board or of such committee, as the case may be, and such written consent
is filed with the records of the proceedings of the Board or such committee.

     SECTION 3.07.  Conference Telephone Meetings.  Members of the Board of
Directors, or any committee thereof, may participate in a meeting of the Board
of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting shall
constitute presence in person at such meeting.

     SECTION 3.08.  Quorum.  At all meetings of the Board of Directors, a
majority of the entire Board of Directors (as defined in Section 3.09(a)) shall
constitute a quorum for the transaction of business.  At all meetings of the
committees of the Board of Directors, the presence of 50% or more of the total
number of members (assuming no vacancies) shall constitute a quorum.  The act of
the directors or committee members present at any meeting at which there is a
quorum shall be the act of the Board of Directors or such committee, as the case
may be, except as otherwise provided in the Delaware General Corporation Law,
the Amended and Restated Certificate of Incorporation or these Amended and
Restated Bylaws.  If a quorum shall not be present at any meeting of the Board
of Directors or any committee, a majority of the directors or members, as the
case may be, present thereat may adjourn the meeting from time to time without
further notice other than announcement at the meeting.  If permitted by
applicable law, the directors or members, as the case may be, present at a duly
authorized meeting may continue to transact business until adjournment,
notwithstanding the withdrawal of enough directors to leave less than a quorum.

     SECTION 3.09.  Committees.  (a)  The Corporation shall have four standing

affiliate of the Corporation.

     (c)  The audit committee shall have the following powers and authority:

internal controls, and to take such action with respect thereto as may seem
appropriate, (iii) to review the accounting principles employed in financial
reporting and (iv) to exercise such additional powers and authority as the Board
of Directors may from time to time determine.  None of the members of the audit

rate in excess of such amount per annum as may be fixed or determined from time
to time by the Board of Directors, (ii) performing the duties of the committees
of the Board of Directors provided for in any present or future stock option,

Corporation or any Subsidiary that the compensation committee shall from time to
time consider appropriate, and (iv) such additional powers and authority as the
Board of Directors may from time to time determine.  None of the members of the
compensation committee shall be a member of the executive committee or an
officer or full-time employee of the Corporation or of any subsidiary or
affiliate of the Corporation.

three-quarters vote of the entire Board of Directors, designate one or more
additional committees, with each such committee consisting of one or more
directors of the Corporation and having such powers and authority as the Board
of Directors shall designate by such resolutions.

     (f)  Any modification to the powers and authority of any committee shall
require the adoption of a resolution by a three-quarters vote of the entire
Board of Directors.

authority pursuant to these Amended and Restated Bylaws and the resolutions
adopted by the Board of Directors in accordance with the terms hereof shall be
deemed to be, and may be certified as being, done or conferred under authority
of the Board of Directors.  The Secretary or any Assistant Secretary is

Bylaws.

     SECTION 3.10.  Committee Members.  (a)  Each member of any committee of the

change the chairmanship of a committee only by resolution adopted by a three-
quarters vote of the entire Board of Directors.

     (c)  The Board of Directors may designate one or more directors as
alternate members of any committee to fill any vacancy on a committee and to

                       STOCK CERTIFICATES AND TRANSFERS
                                        

     SECTION 5.01.  Stock Certificates and Transfers.  (a)  The interest of each
stockholder of the Corporation shall be evidenced by certificates for shares of
stock in such form as the appropriate officers of the Corporation may from time
to time prescribe; provided that the Board of Directors may provide by
resolution or resolutions that all or some of all classes or series of the stock
of the Corporation shall be represented by uncertificated shares.
Notwithstanding the adoption of such a resolution by the Board of Directors,
every holder of stock represented by certificates and upon request every holder
of uncertificated shares shall be entitled to have a certificate signed by, or
in the name of the Corporation by the Chairman of the Board of Directors, or the
President or any other authorized officer and by the Treasurer or an Assistant
Treasurer, or the Secretary or an Assistant Secretary of the Corporation
representing the number of shares registered in certificate form.  Except as
otherwise expressly provided by law, the rights and obligations of the holders
of uncertificated stock and the rights and obligations of the holders of
certificates representing stock of the same class and series shall be identical.

     (b)  The certificates of stock shall be signed, countersigned and
registered in such manner as the Board of Directors may by resolution prescribe,
which resolution may 

                                       12
<PAGE>
 
permit all or any of the signatures on such certificates to be in facsimile. In
case any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate has ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the Corporation with the same effect as if he were such officer, transfer
agent or registrar at the date of issue.

     (c)  The shares of the stock of the Corporation represented by certificates
shall be transferred on the books of the Corporation by the holder thereof in
person or by his attorney, upon surrender for cancelation of certificates for
the same number of shares, with an assignment and power of transfer endorsed
thereon or attached thereto, duly executed, with such proof of the authenticity
of the signature as the Corporation or its agents may reasonably require.  Upon
receipt of proper transfer instructions from the registered owner of
uncertificated shares such uncertificated shares shall be canceled and issuance
of new equivalent uncertificated shares or certificated shares shall be made to
the person entitled thereto and the transaction shall be recorded upon the books
of the Corporation.  Within a reasonable time after the issuance or transfer of
uncertificated stock, the Corporation shall send to the registered owner thereof
a written notice containing the information required to be set forth or stated
on certificates pursuant to the Delaware General Corporation Law or, unless
otherwise provided by the Delaware General Corporation Law, a statement that the
Corporation will furnish without charge to each stockholder who so requests the
powers, designations, preferences and relative participating, optional or other
special rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

     SECTION 5.02.  Lost, Stolen or Destroyed Certificates.  No certificate for
shares or uncertificated shares of stock in the Corporation shall be issued in
place of any certificate alleged to have been lost, destroyed or stolen, except

delivery to the Corporation of a bond of indemnity in such amount, upon such
terms and secured by such surety, as the Board of Directors or its designee may
in its or his discretion require.

     SECTION 6.03.  Seal.  The corporate seal shall have thereon the name of the
Corporation and shall be in such form as may be approved from time to time by
the Board of Directors.

     SECTION 6.04.  Waiver of Notice.  Whenever any notice is required to be
given to any stockholder or director of the Corporation under the provisions of
the General Corporation Law of the State of Delaware, a waiver thereof in
writing, signed by the person or persons entitled to such notice, whether before
or after the time stated therein, shall be deemed equivalent to the giving of
such notice.  Neither the business to be transacted at, nor the purpose of, any
annual or special meeting of the stockholders or any meeting of the Board of
Directors or committee thereof need be specified in any waiver of notice of such
meeting.

     SECTION 6.05.  Audits.  The accounts, books and records of the Corporation
shall be audited upon the conclusion of each fiscal year by an independent
certified public accountant selected by the audit committee, and it shall be the
duty of the audit committee to cause such audit to be made annually.

     SECTION 6.06.  Resignations.  Any director or any officer, whether elected
or appointed, may resign at any time upon notice of such resignation to the
Corporation.

     SECTION 6.07.  Indemnification and Insurance.

     (a)  Each person who was or is made a party or is threatened to be made a
party to or is involved in any manner in any threatened, pending or completed
action, suit, or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), by reason of the fact that he or she
or a person of whom he or she is the legal representative is or was a director
or officer of the Corporation or a director or elected officer of a Subsidiary,
shall be indemnified and held harmless by the Corporation to the fullest extent
permitted from time to time by the General Corporation Law of the State of
Delaware as the same exists or may hereafter be amended (but, if permitted by
applicable law, in the case of any such amendment, only to the extent that such
amendment permits the Corporation to provide broader indemnification rights than
said law permitted the Corporation to provide prior to such amendment) or any
other applicable laws as presently or hereafter in effect, and such
indemnification shall continue as to a person who has ceased to be a director or
officer and shall inure to the benefit of his or her heirs, executors and
administrators; provided however, that the Corporation shall indemnify any such
person seeking indemnification in connection with a proceeding (or part thereof)
initiated by such person only if such proceeding (or part thereof) was
authorized by the Board of Directors or is a proceeding to enforce such person's
claim to indemnification pursuant to the rights granted by this Bylaw.  The
Corporation shall pay the expenses incurred by such person in defending any such
proceeding in advance of its final disposition upon receipt (unless the
Corporation upon authorization of the Board of Directors waives such requirement
to the extent permitted by applicable law) of an undertaking by or on behalf of
such person to repay such amount if it shall ultimately be 

                                       14
<PAGE>
 
determined that such person is not entitled to be indemnified by the Corporation
as authorized in this Bylaw or otherwise.

     (b)  The indemnification and the advancement of expenses incurred in
defending a proceeding prior to its final disposition provided by, or granted
pursuant to this Bylaw shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, provision of the Amended
and Restated Certificate of Incorporation, other provision of these Amended and
Restated Bylaws, agreement, vote of stockholders or Disinterested Directors or
otherwise.  No repeal, modification or amendment of, or adoption of any
provision inconsistent with, this Section 6.07, nor to the fullest extent
permitted by applicable law, any modification of law, shall adversely affect any
right or protection of any person granted pursuant hereto existing at, or with
respect to any events that occurred prior to, the time of such repeal,
amendment, adoption or modification.

     (c)  The Corporation may maintain insurance, at its expense, to protect
itself and any person who is or was a director, officer, partner, member,
employee or agent of the Corporation or a Subsidiary or of another corporation,
partnership, limited liability company, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the Corporation would
have the power to indemnify such person against such expense, liability or loss
under the General Corporation Law of the State of Delaware.

     (d)  The Corporation may, to the extent authorized from time to time by the
Board of Directors, grant rights to indemnification, and rights to be paid by
the Corporation the expenses incurred in defending any proceeding in advance of
its final disposition, to any person who is or was an employee or agent (other
than a director or officer) of the Corporation or a Subsidiary and to any person
who is or was serving at the request of the Corporation or a Subsidiary as a
director, officer, partner, member, employee or agent of another corporation,
partnership, limited liability company, joint venture, trust or other
enterprise, including service with respect to employee benefit plans maintained
or sponsored by the Corporation or a Subsidiary, to the fullest extent of the
provisions of this Bylaw with respect to the indemnification and advancement of
expenses of directors and officers of the Corporation.

     (e)  If any provision or provisions of this Bylaw shall be held to be
invalid, illegal or unenforceable for any reason whatsoever: (1) the validity,
the legality and enforceability of the remaining provisions of this Bylaw
(including, without limitation, each portion of any paragraph or clause of this
Bylaw containing any such provision held to be invalid, illegal or
unenforceable, that is not itself held to be invalid, illegal or unenforceable)
shall not in any way be affected or impaired thereby; and (2) to the fullest
extent possible, the provisions of this Bylaw (including, without limitation,
each such portion of any paragraph of this Bylaw containing any such provision
held to be invalid, illegal or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal or
unenforceable.

                                       15

     (f)  For purposes of these Amended and Restated Bylaws:

     (1)  "Disinterested Director" means a director of the Corporation who is
not and was not a party to the proceeding or matter in respect of which
indemnification is sought by the claimant.

     (2)  "Subsidiary" means a corporation, a majority of the capital stock of
which is owned directly or indirectly by the Corporation, other than directors'
qualifying shares.

     (g)  Any notice, request, or other communication required or permitted to
be given to the Corporation under this Bylaw shall be in writing and either
delivered in person or sent by telecopy, telex, telegram, overnight mail or
courier service, or certified or registered mail, postage prepaid, return
receipt requested, to the Secretary of the Corporation and shall be effective
only upon receipt by the Secretary.

                           CONTRACTS, PROXIES, ETC.
                                        

     SECTION 7.01.  Contracts.  Except as otherwise required by law, the Amended
and Restated Certificate of Incorporation or these Amended and Restated Bylaws,
any contracts or other instruments may be executed and delivered in the name and

as the Board of Directors may from time to time direct.  Such authority may be
general or confined to specific instances as the Board may determine.  Subject
to the control and direction of the Board of Directors, the Chairman of the
Board, the President, the Chief Financial Officer, the Chief Strategic and
Administrative Officer, the Chief Legal Officer and the Treasurer may enter
into, execute, deliver and amend bonds, promissory notes, contracts, agreements,
deeds, leases, guarantees, loans, commitments, obligations, liabilities and
other instruments to be made or executed for or on behalf of the Corporation.
Subject to any restrictions imposed by the Board of Directors, such officers of
the Corporation may delegate such powers to others under his or her
jurisdiction, it being understood, however, that any such delegation of power
shall not relieve such officer of responsibility with respect to the exercise of
such delegated power.

     SECTION 7.02.  Proxies.  Unless otherwise provided by resolution adopted by
the Board of Directors, the Chairman of the Board or the President may from time
to time appoint an attorney or attorneys or agent or agents of the Corporation,

Corporation may be entitled to cast as the holder of stock or other securities
in any other corporation or entity, any of whose stock or other securities may
be held by the Corporation, at meetings of the holders of the stock or other
securities of such other corporation or entity, or to consent in writing, in the
name of the Corporation as such holder, to any action by such other corporation
or entity, and may instruct the person or persons so appointed as to the manner
of casting such vote or giving such consent, and may execute or cause to be
executed in the name 

                                       16

and on behalf of the Corporation and under its corporate seal or otherwise, all
such written proxies or other instruments as he may deem necessary or proper in
the premises.

altered, amended or repealed, in whole or in part, or new Amended and Restated
Bylaws may be adopted by the stockholders or by the Board of Directors at any
meeting thereof; provided however, that notice of such alteration, amendment,
repeal or adoption of new Amended and Restated Bylaws is contained in the notice
of such meeting of stockholders or in the notice of such meeting of the Board of
Directors and, in the latter case, such notice is given not less than twenty-

<PAGE>
 
determination of Holders to whom interest is payable and/or the method by which
such rate or rates or date or dates shall be determined;

     (f) the place or places where the principal of and any interest on
Securities of the series shall be payable (if other than as provided in Section
3.02), the place or places where the Securities of the series may be presented
for registration of transfer or exchange and the place or places where notices
and demands to or upon the Issuer in respect of the Securities of the series may
be made;

     (g) any provisions relating to the deferral of interest payments on the

     (l) if other than the principal amount thereof, the portion of the
principal amount of Securities of the series which shall be payable upon
declaration of acceleration of the maturity thereof;

     (m) if other than the coin or currency in which the Securities of that
series are denominated, the coin or currency in which payment of the principal

<PAGE>
 
adjustment thereof and the period during which such Securities may be so

combination of the foregoing, any restrictions applicable to the offer, sale or
delivery of Unregistered Securities or the payment of interest thereon and, if

amounts ("ADDITIONAL SUMS") on the Securities of the series held by a person who
is not a U.S. person or held in an MSDW Capital Trust in respect of any tax,
assessment or governmental charge withheld or deducted and, if so, whether the
Issuer will have the option to redeem such Securities rather than pay such
Additional Sums;

     (s) if the Securities of such series are to be issuable in definitive form

series) only upon receipt of certain certificates or other documents or
satisfaction of other conditions, the form and terms of such certificates,

<PAGE>
 
     (v) any other terms of the series (which terms shall not be inconsistent
with the provisions of this Indenture).

     All Securities of any one series and Coupons, if any, appertaining thereto,
shall be substantially identical, except in the case of Registered Securities as
to denomination and except as may otherwise be provided by or pursuant to the
Board Resolution or Officer's Certificate referred to above or as set forth in
any such indenture supplemental hereto. All Securities of any one series need
not be issued at the same time and may be issued from time to time, consistent
with the terms of this Indenture, if so provided by or pursuant to such Board
Resolution, such Officer's Certificate or in any such indenture supplemental
hereto.

     Section 2.04.  Authentication and Delivery of Securities.  The Issuer may
deliver Securities of any series having attached thereto appropriate Coupons, if
any, executed by the Issuer to the Trustee for authentication together with the
applicable documents referred to below in this Section, and the Trustee shall
thereupon manually authenticate and deliver such Securities to or upon the order
of the Issuer (contained in the Issuer Order referred to below in this Section)
or pursuant to such procedures acceptable to the Trustee and to such recipients
as may be specified from time to time by an Issuer Order. The maturity date,
original issue date, interest rate and any other terms of the Securities of such
series and Coupons, if any, appertaining thereto shall be determined by or
pursuant to such Issuer Order and procedures. If provided for in such
procedures, such Issuer Order may authorize authentication and delivery pursuant
to oral instructions from the Issuer or its duly authorized agent, which
instructions shall be promptly confirmed in writing. In authenticating such
Securities and accepting the additional responsibilities under this Indenture in
relation to such Securities, the Trustee shall be entitled to receive (in the
case of subparagraphs (b), (c) and (d) below only at or before the time of the
first request of the Issuer to the Trustee to authenticate Securities of such
series) and (subject to Section 6.01) shall be fully protected in relying upon,
unless and until such documents have been superceded or revoked:

     (a) an Issuer Order requesting such authentication and setting forth
delivery instructions if the Securities and Coupons, if any, are not to be
delivered to the Issuer, provided that, with respect to Securities of a series
subject to a Periodic Offering, (i) such Issuer Order may be delivered by the
Issuer to the Trustee prior to the delivery to the Trustee of such Securities
for authentication and delivery, (ii) the Trustee shall authenticate and deliver
Securities of such series for original issue from time to time, in an aggregate
principal amount not exceeding the aggregate principal amount established for
such series, pursuant to an Issuer Order or pursuant to procedures acceptable to
the Trustee as may be

                                       14
<PAGE>
 
specified from time to time by an Issuer Order, (iii) the maturity date or
dates, original issue date or dates, interest rate or rates and any other terms
of Securities of such series shall be determined by an Issuer Order or pursuant
to such procedures and (iv) if provided for in such procedures, such Issuer
Order may authorize authentication and delivery pursuant to oral or electronic
instructions from the Issuer or its duly authorized agent or agents, which oral
instructions shall be promptly confirmed in writing;

     (b) any Board Resolution, Officer's Certificate and/or executed
supplemental indenture referred to in Sections 2.01 and 2.03 by or pursuant to 
which the forms and terms of the Securities and Coupons, if any, were
established;

     (c) an Officer's Certificate setting forth the form or forms and terms of
the Securities and Coupons, if any, stating that the form or forms and terms of
the Securities and Coupons, if any, have been established pursuant to Sections
2.01 and 2.03 and comply with this Indenture, and covering such other matters 
as the Trustee may reasonably request; and

     (d) at the option of the Issuer, either an Opinion of Counsel, or a letter
addressed to the Trustee permitting it to rely on an Opinion of Counsel,
substantially to the effect that:

               (i) the forms of the Securities and Coupons, if any, have been
     duly authorized and established in conformity with the provisions of this
     Indenture;

               (ii) in the case of an underwritten offering, the terms of the
     Securities have been duly authorized and established in conformity with the
     provisions of this Indenture, and, in the case of an offering that is not
     underwritten, certain terms of the Securities have been established
     pursuant to a Board Resolution, an Officer's Certificate or a supplemental
     indenture in accordance with this Indenture, and when such other terms as
     are to be established pursuant to procedures set forth in an Issuer Order
     shall have been established, all such terms will have been duly authorized
     by the Issuer and will have been established in conformity with the
     provisions of this Indenture;

               (iii)     when the Securities and Coupons, if any, have been
     executed by the Issuer and authenticated by the Trustee in accordance with
     the provisions of this Indenture and delivered to and duly paid for by the
     purchasers thereof, they will have been duly issued under this Indenture
     and will be valid and legally binding obligations of the Issuer,
     enforceable

                                       15
<PAGE>
 
     in accordance with their respective terms, and will be entitled to the
     benefits of this Indenture; and

               (iv) the execution and delivery by the Issuer of, and the
     performance by the Issuer of its obligations under, the Securities and
     Coupons, if any, will not contravene any provision of applicable law or the
     certificate of incorporation or by-laws of the Issuer or any agreement or
     other instrument binding upon the Issuer or any of its subsidiaries that is
     material to the Issuer and its subsidiaries, considered as one enterprise,
     or, to the best of such counsel's knowledge, any judgment, order or decree
     of any governmental body, agency or court having jurisdiction over the
     Issuer or any subsidiary, and no consent, approval or authorization of any
     governmental body or agency is required for the performance by the Issuer
     of its obligations under the Securities and Coupons, if any, except such as
     are specified and have been obtained and such as may be required by the
     securities or blue sky laws of the various states in connection with the
     offer and sale of the Securities and Coupons, if any.

          In rendering such opinions, such counsel may qualify any opinions as
to enforceability by stating that such enforceability may be limited by
bankruptcy, insolvency, reorganization, liquidation, moratorium and other
similar laws affecting the rights and remedies of creditors and is subject to
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law). Such counsel may rely, as to
all matters governed by the laws of jurisdictions other than the State of New
York and the federal law of the United States, upon opinions of other counsel
(copies of which shall be delivered to the Trustee), who shall be counsel
reasonably satisfactory to the Trustee, in which case the opinion shall state
that such counsel believes he and the Trustee are entitled so to rely. Such
counsel may also state that, insofar as such opinion involves factual matters,
he has relied, to the extent he deems proper, upon certificates of officers of
the Issuer and its subsidiaries and certificates of public officials.

          The Trustee shall have the right to decline to authenticate and
deliver any Securities under this Section if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken by the Issuer or
if the Trustee in good faith by its board of directors or board of trustees,
executive committee, or a trust committee of directors or trustees or
Responsible Officers shall determine that such action would expose the Trustee
to personal liability to existing Holders or would affect the Trustee's own
rights, duties or immunities under the Securities, this Indenture or otherwise.

          If the Issuer shall establish pursuant to Section 2.03 that the
Securities of a series are to be issued in the form of one or more Registered
Global Securities, then the Issuer shall execute and the Trustee shall, in
accordance with this Section and the Issuer Order with respect to such series,
authenticate and deliver one or more Registered Global Securities that (i) shall
represent and shall be denominated in an amount equal to the aggregate principal
amount of all of the Securities of such series issued and not yet cancelled,
(ii) shall be registered in the name of the Depositary for such Registered
Global Security or Securities or the nominee of such Depositary, (iii) shall be
delivered by the Trustee to such Depositary or pursuant to such Depositary's
instructions and (iv) shall bear a legend substantially to the following effect:
"Unless and until it is exchanged in whole or in part for Securities in
definitive registered form, this Security may not be transferred except as a
whole by the Depositary to the 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."

          Each Depositary designated pursuant to Section 2.03 must, at the time
of its designation and at all times while it serves as Depositary, be a clearing
agency registered under the Securities Exchange Act of 1934 and any other
applicable statute or regulation.

          Section 2.05.  Execution of Securities.  The Securities and, if
applicable, each Coupon appertaining thereto shall be signed on behalf of the
Issuer by one of the following: the Chairman of the Board, the President, the
Chief Financial Officer, the Chief Strategic and Administrative Officer, the
Chief Legal Officer, the Treasurer, any Assistant Treasurer or any other person
authorized by the Board of Directors to execute Securities or, if applicable,
Coupons, which Securities or Coupons may, but need not, be attested. Such
signatures may be the manual or facsimile signatures of the present or any
future such officers.  Minor errors or defects in any such reproduction of any
such signature shall not affect the validity or enforceability of any Security
that has been duly authenticated and delivered by the Trustee.

          In case any officer of the Issuer who shall have signed any of the
Securities or Coupons, if any, shall cease to be such officer before the
Security or Coupon so signed (or the Security to which the Coupon so signed
appertains) shall be authenticated and delivered by the Trustee or disposed of
by the Issuer, such Security or Coupon nevertheless may be authenticated and
delivered or disposed of as though the person who signed such Security or Coupon
had not ceased to be such officer of the Issuer; and any Security or Coupon may
be signed on behalf of the Issuer by such persons as, at the actual date of the
execution of such Security or Coupon, shall be the proper officers of the
Issuer, although at the

                                       17
<PAGE>
 
date of the execution and delivery of this Indenture any such person was not
such an officer.

          SECTION 2.06. Certificate of Authentication. Only such Securities as
shall bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by the Trustee by the manual signature of one of
its authorized officers, shall be entitled to the benefits of this Indenture or
be valid or obligatory for any purpose. No Coupon shall be entitled to the
benefits of this Indenture or shall be valid and obligatory for any purpose
until the certificate of authentication on the Security to which such Coupon
appertains shall have been duly executed by the Trustee. The execution of such
certificate by the Trustee upon any Security executed by the Issuer shall be
conclusive evidence that the Security so authenticated has been duly
authenticated and delivered hereunder and that the Holder is entitled to the
benefits of this Indenture.

          SECTION 2.07. Denomination and Date of Securities; Payments of
Interest. The Securities of each series shall be issuable as Registered
Securities or Unregistered Securities in denominations established as
contemplated by Section 2.03 or, with respect to the Registered Securities of
any series, if not so established, in denominations of $1,000 and any integral
multiple thereof. If denominations of Unregistered Securities of any series are
not so established, such Securities shall be issuable in denominations of $1,000
and $5,000. The Securities of each series shall be numbered, lettered or
otherwise distinguished in such manner or in accordance with such plan as the
officers of the Issuer executing the same may determine with the approval of the
Trustee, as evidenced by the execution and authentication thereof.

          Each Registered Security shall be dated the date of its
authentication. Each Unregistered Security shall be dated as provided in the
resolution or resolutions of the Board of Directors of the Issuer referred to in
Section 2.03. The Securities of each series shall bear interest, if any, from
the date, and such interest shall be payable on the dates, established as
contemplated by Section 2.03.

          The person in whose name any Registered Security of any series is
registered at the close of business on any record date applicable to a
particular series with respect to any interest payment date for such series
shall be entitled to receive the interest, if any, payable on such interest
payment date notwithstanding any transfer or exchange of such Registered
Security subsequent to the record date and prior to such interest payment date,
except if and to the extent the Issuer shall default in the payment of the
interest due on such interest payment date for such series, in which case such
defaulted interest shall be paid to the persons in whose names Outstanding
Registered Securities for such series are registered at the close of business on
a subsequent record date (which shall be not less than five

                                                                        

                                       18
<PAGE>
 
Business Days prior to the date of payment of such defaulted interest)
established by notice given by mail by or on behalf of the Issuer to the Holders
of Registered Securities not less than 15 days preceding such subsequent record
date. The term "RECORD DATE" as used with respect to any interest payment date
(except a date for payment of defaulted interest) for the Securities of any
series shall mean the date specified as such in the terms of the Registered
Securities of such series established as contemplated by Section 2.03, or, if no
such date is so established, if such interest payment date is the first day of a
calendar month, the fifteenth day of the next preceding calendar month or, if
such interest payment date is the fifteenth day of a calendar month, the first
day of such calendar month, whether or not such record date is a Business Day.

          SECTION 2.08. Registration, Transfer and Exchange. The Issuer will
keep at each office or agency to be maintained for the purpose as provided in
Section 3.02 for each series of Securities a register or registers in which,
subject to such reasonable regulations as it may prescribe, it will provide for
the registration of Registered Securities of such series and the registration of
transfer of Registered Securities of such series. Such register shall be in
written form in the English language or in any other form capable of being
converted into such form within a reasonable time. At all reasonable times such
register or registers shall be open for inspection by the Trustee.

          Upon due presentation for registration of transfer of any Registered
Security of any series at any such office or agency to be maintained for the
purpose as provided in Section 3.02, the Issuer shall execute and the Trustee
shall authenticate and deliver in the name of the transferee or transferees a
new Registered Security or Registered Securities of the same series, maturity
date, interest rate and original issue date in authorized denominations for a
like aggregate principal amount.

          Unregistered Securities (except for any temporary global
Unregistered Securities) and Coupons (except for Coupons attached to any
temporary global Unregistered Securities) shall be transferable by delivery.

          At the option of the Holder thereof, Registered Securities of any
series (other than a Registered Global Security, except as set forth below) may
be exchanged for a Registered Security or Registered Securities of such series
having authorized denominations and an equal aggregate principal amount, upon
surrender of such Registered Securities to be exchanged at the agency of the
Issuer that shall be maintained for such purpose in accordance with Section 3.02
and upon payment, if the Issuer shall so require, of the charges hereinafter
provided. If the Securities of any series are issued in both registered and
unregistered form, except as otherwise specified pursuant to Section 2.03, at
the

                                       19
<PAGE>
 
option of the Holder thereof, Unregistered Securities of any series may be
exchanged for Registered Securities of such series having authorized
denominations and an equal aggregate principal amount, upon surrender of such
Unregistered Securities to be exchanged at the agency of the Issuer that shall
be maintained for such purpose in accordance with Section 3.02, with, in the
case of Unregistered Securities that have Coupons attached, all unmatured
Coupons and all matured Coupons in default thereto appertaining, and upon
payment, if the Issuer shall so require, of the charges hereinafter provided. At
the option of the Holder thereof, if Unregistered Securities of any series,
maturity date, interest rate and original issue date are issued in more than one
authorized denomination, except as otherwise specified pursuant to Section 2.03,
such Unregistered Securities may be exchanged for Unregistered Securities of
such series having authorized denominations and an equal aggregate principal
amount, upon surrender of such Unregistered Securities to be exchanged at the
agency of the Issuer that shall be maintained for such purpose in accordance
with Section 3.02 or as specified pursuant to Section 2.03, with, in the case of
Unregistered Securities that have Coupons attached, all unmatured Coupons and
all matured Coupons in default thereto appertaining, and upon payment, if the
Issuer shall so require, of the charges hereinafter provided. Unless otherwise
specified pursuant to Section 2.03, Registered Securities of any series may not
be exchanged for Unregistered Securities of such series. Whenever any Securities
are so surrendered for exchange, the Issuer shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive. All Securities and Coupons surrendered upon any exchange or
transfer provided for in this Indenture shall be promptly cancelled and disposed
of by the Trustee and the Trustee will deliver a certificate of disposition
thereof to the Issuer.

          All Registered Securities presented for registration of transfer,
exchange, redemption or payment shall (if so required by the Issuer or the
Trustee) be duly endorsed by, or be accompanied by a written instrument or
instruments of transfer in form satisfactory to the Issuer and the Trustee duly
executed by the Holder or his attorney duly authorized in writing.

          The Issuer may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection with any exchange
or registration of transfer of Securities. No service charge shall be made for
any such transaction.

          The Issuer shall not be required to exchange or register a transfer
of (a) any Securities of any series for a period of 15 days next preceding the
first mailing of notice of redemption of Securities of such series to be
redeemed or (b) any Securities selected, called or being called for redemption,
in whole or in part,

                                       20
<PAGE>
 
except, in the case of any Security to be redeemed in part, the portion thereof
not so to be redeemed.

          Notwithstanding any other provision of this Section 2.08, unless and
until it is exchanged in whole or in part for Securities in definitive
registered form, a Registered Global Security representing all or a portion of
the Securities of a series may not be transferred except as a whole by the
Depositary for such series to a nominee of such Depositary or by a nominee of
such Depositary to such Depositary or another nominee of such Depositary or by
such Depositary or any such nominee to a successor Depositary for such series or
a nominee of such successor Depositary.

          If at any time the Depositary for any Registered Securities of a
series represented by one or more Registered Global Securities notifies the
Issuer that it is unwilling or unable to continue as Depositary for such
Registered Securities or if at any time the Depositary for such Registered
Securities shall no longer be eligible under Section 2.04, the Issuer shall
appoint a successor Depositary eligible under Section 2.04 with respect to such
Registered Securities. If a successor Depositary eligible under Section 2.04 for
such Registered Securities is not appointed by the Issuer within 90 days after
the Issuer receives such notice or becomes aware of such ineligibility, the
Issuer's election pursuant to Section 2.03 that such Registered Securities be
represented by one or more Registered Global Securities shall no longer be
effective and the Issuer will execute, and the Trustee, upon receipt of an
Officer's Certificate for the authentication and delivery of definitive
Securities of such series, will authenticate and deliver, Securities of such
series in definitive registered form without coupons, in any authorized
denominations, in an aggregate principal amount equal to the principal amount of
the Registered Global Security or Securities representing such Registered
Securities in exchange for such Registered Global Security or Securities.

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

          If specified by the Issuer pursuant to Section 2.03 with respect to
Securities represented by a Registered Global Security, the Depositary for such

                                       21
<PAGE>
 
Registered Global Security may surrender such Registered Global Security in
exchange in whole or in part for Securities of the same series in definitive
registered form on such terms as are acceptable to the Issuer and such
Depositary. Thereupon, the Issuer shall execute, and the Trustee shall
authenticate and deliver, without service charge,

          (a) to the Person specified by such Depositary a new Registered
Security or Securities of the same series, of any authorized denominations as
requested by such Person, in an aggregate principal amount equal to and in
exchange for such Person's beneficial interest in the Registered Global
Security; and

          (b) to such Depositary a new Registered Global Security in a
denomination equal to the difference, if any, between the principal amount of
the surrendered Registered Global Security and the aggregate principal amount of
Registered Securities authenticated and delivered pursuant to clause (a) above.

          Upon the exchange of a Registered Global Security for Securities in
definitive registered form without coupons, in authorized denominations, such
Registered Global Security shall be cancelled by the Trustee or an agent of the
Issuer or the Trustee. Securities in definitive registered form without coupons
issued in exchange for a Registered Global Security pursuant to this Section
2.08 shall be registered in such names and in such authorized denominations as
the Depositary for such Registered Global Security, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee or an agent of the Issuer or the Trustee. The Trustee or such agent
shall deliver such Securities to or as directed by the Persons in whose names
such Securities are so registered.

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

          Notwithstanding anything herein or in the terms of any series of
Securities to the contrary, none of the Issuer, the Trustee or any agent of the
Issuer or the Trustee (any of which, other than the Issuer, shall rely on an
Officer's Certificate and an Opinion of Counsel) shall be required to exchange
any Unregistered Security for a Registered Security if such exchange would
result in adverse Federal income tax consequences to the Issuer (such as, for
example, the inability of the Issuer to deduct from its income, as computed for
Federal income tax purposes, the interest payable on the Unregistered
Securities) under then applicable United States Federal income tax laws.

          SECTION 2.09. Mutilated, Defaced, Destroyed, Lost and Stolen
Securities. In case any temporary or definitive Security or any Coupon
appertaining to any Security shall become mutilated, defaced or be destroyed,
lost or stolen, the Issuer in its discretion may execute, and upon the written
request of any officer of the Issuer, the Trustee shall authenticate and deliver
a new Security of the same series, maturity date, interest rate and original
issue date, bearing a number or other distinguishing symbol not
contemporaneously outstanding, in exchange and substitution for the mutilated or
defaced Security, or in lieu of and in substitution for the Security so
destroyed, lost or stolen with Coupons corresponding to the Coupons appertaining
to the Securities so mutilated, defaced, destroyed, lost or stolen, or in
exchange or substitution for the Security to which such mutilated, defaced,
destroyed, lost or stolen Coupon appertained, with Coupons appertaining thereto
corresponding to the Coupons so mutilated, defaced, destroyed, lost or stolen.
In every case the applicant for a substitute Security or Coupon shall furnish to
the Issuer and to the Trustee and any agent of the Issuer or the Trustee such
security or indemnity as may be required by them to indemnify and defend and to
save each of them harmless and, in every case of destruction, loss or theft,
evidence to their satisfaction of the destruction, loss or theft of such
Security or Coupon and of the ownership thereof and in the case of mutilation or
defacement shall surrender the Security and related Coupons to the Trustee or
such agent.

          Upon the issuance of any substitute Security or Coupon, the Issuer
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee or its agent) connected
therewith. In case any Security or Coupon which has matured or is about to
mature or has been called for redemption in full shall become mutilated or
defaced or be destroyed, lost or stolen, the Issuer may instead of issuing a
substitute Security, pay or authorize the payment of the same or the relevant
Coupon (without surrender thereof except in the case of a mutilated or defaced
Security or Coupon), if the applicant for such payment shall furnish to the
Issuer and to the Trustee and any agent of the Issuer or the Trustee such
security or indemnity as any of them may require to save each of them harmless,
and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Issuer and the Trustee and any agent of the Issuer or the Trustee
evidence to their satisfaction of the destruction, loss or theft of such
Security or Coupon and of the ownership thereof.

          Every substitute Security or Coupon of any series issued pursuant to
the provisions of this Section by virtue of the fact that any such Security or
Coupon is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Issuer, whether or not the destroyed, lost or stolen Security
or Coupon shall be at any time enforceable by anyone and shall be entitled to
all the benefits of (but shall be subject to all the limitations of rights set
forth in) this Indenture equally

                                       23
<PAGE>
 
and proportionately with any and all other Securities or Coupons of such series
duly authenticated and delivered hereunder. All Securities and Coupons shall be
held and owned upon the express condition that, to the extent permitted by law,
the foregoing provisions are exclusive with respect to the replacement or
payment of mutilated, defaced or destroyed, lost or stolen Securities and
Coupons and shall preclude any and all other rights or remedies notwithstanding
any law or statute existing or hereafter enacted to the contrary with respect to
the replacement or payment of negotiable instruments or other securities without
their surrender.

          SECTION 2.10. Cancellation of Securities; Destruction Thereof. All
Securities and Coupons surrendered for payment, redemption, registration of
transfer or exchange, or for credit against any payment in respect of a sinking
or analogous fund, if surrendered to the Issuer or any agent of the Issuer or
the Trustee or any agent of the Trustee, shall be delivered to the Trustee or
its agent for cancellation or, if surrendered to the Trustee, shall be cancelled
by it; and no Securities or Coupons shall be issued in lieu thereof except as
expressly permitted by any of the provisions of this Indenture. The Trustee or
its agent shall return such cancelled Securities and Coupons held by it to the
Issuer. If the Issuer or its agent shall acquire any of the Securities or
Coupons, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Securities or Coupons unless and until the
same are delivered to the Trustee or its agent for cancellation.

          SECTION 2.11. Temporary Securities. Pending the preparation of
definitive Securities for any series, the Issuer may execute and the Trustee
shall authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be
issuable as Registered Securities without coupons, or as Unregistered Securities
with or without coupons attached thereto, of any authorized denomination, and
substantially in the form of the definitive Securities of such series but with
such omissions, insertions and variations as may be appropriate for temporary
Securities, all as may be determined by the Issuer with the concurrence of the
Trustee as evidenced by the execution and authentication thereof. Temporary
Securities may contain such references to any provisions of this Indenture as
may be appropriate. Every temporary Security shall be executed by the Issuer and
be authenticated by the Trustee upon the same conditions and in substantially
the same manner, and with like effect, as the definitive Securities. Without
unreasonable delay the Issuer shall execute and shall furnish definitive
Securities of such series and thereupon temporary Registered Securities of such
series may be surrendered in exchange therefor without charge at each office or
agency to be maintained by the Issuer for that purpose pursuant to Section 3.02
and, in the case of Unregistered Securities, at any agency maintained by the
Issuer for such

                                       24
<PAGE>
 
purpose as specified pursuant to Section 2.03, and the Trustee shall
authenticate and deliver in exchange for such temporary Securities of such
series an equal aggregate principal amount of definitive Securities of the same
series having authorized denominations and, in the case of Unregistered
Securities, having attached thereto any appropriate Coupons. Until so exchanged,
the temporary Securities of any series shall be entitled to the same benefits
under this Indenture as definitive Securities of such series, unless otherwise
established pursuant to Section 2.03. The provisions of this Section are subject
to any restrictions or limitations on the issue and delivery of temporary
Unregistered Securities of any series that may be established pursuant to
Section 2.03 (including any provision that Unregistered Securities of such
series initially be issued in the form of a single global Unregistered Security
to be delivered to a depositary or agency located outside the United States and
the procedures pursuant to which definitive or global Unregistered Securities of
such series would be issued in exchange for such temporary global Unregistered
Security).



                                   ARTICLE 3

                            COVENANTS OF THE ISSUER

          SECTION 3.01. Payment of Principal and Interest. The Issuer
covenants and agrees for the benefit of each series of Securities that it will
duly and punctually pay or cause to be paid the principal of, and interest on,
each of the Securities of such series (together with any additional amounts
payable pursuant to the terms of such Securities) at the place or places, at the
respective times and in the manner provided in such Securities and in the
Coupons, if any, appertaining thereto and in this Indenture. The interest on
Securities with Coupons attached (together with any additional amounts payable
pursuant to the terms of such Securities) shall be payable only upon
presentation and surrender of the several Coupons for such interest installments
as are evidenced thereby as they severally mature. If any temporary Unregistered
Security provides that interest thereon may be paid while such Security is in
temporary form, the interest on any such temporary Unregistered Security
(together with any additional amounts payable pursuant to the terms of such
Security) shall be paid, as to the installments of interest evidenced by Coupons
attached thereto, if any, only upon presentation and surrender thereof, and, as
to the other installments of interest, if any, only upon presentation of such
Securities for notation thereon of the payment of such interest, in each case
subject to any restrictions that may be established pursuant to Section 2.03.
The interest on Registered Securities (together with any additional amounts
payable pursuant to the terms of such Securities) shall be payable only to or
upon the written order of the Holders thereof and, at the option

                                       25
<PAGE>
 
of the Issuer, may be paid by wire transfer or by mailing checks for such
interest payable to or upon the written order of such Holders at their last
addresses as they appear on the registry books of the Issuer; provided, however,
that, if the Securities of such series are held by an MSDW Capital Trust or a
trustee of such trust and a holder of a Capital Security of such trust brings a
successful Direct Action with respect to any interest payable on such
Securities, such interest will be payable directly to such holder. In such
event, the Issuer will have the right to set-off such payment to such holder
against its obligation to pay interest on such Securities to such MSDW Capital
Trust.

          SECTION 3.02. Offices for Payments, etc. So long as any Registered
Securities are authorized for issuance pursuant to this Indenture or are
outstanding hereunder, the Issuer will maintain in the Borough of Manhattan, The
City of New York, an office or agency where the Registered Securities of each
series may be presented for payment, where the Securities of each series may be
presented for exchange as is provided in this Indenture and, if applicable,
pursuant to Section 2.03 and where the Registered Securities of each series may
be presented for registration of transfer as in this Indenture provided.

          The Issuer will maintain one or more offices or agencies in a city
or cities located outside the United States (including any city in which such an
agency is required to be maintained under the rules of any stock exchange on
which the Securities of such series are listed) where the Unregistered
Securities, if any, of each series and Coupons, if any, appertaining thereto may
be presented for payment. No payment on any Unregistered Security or Coupon will
be made upon presentation of such Unregistered Security or Coupon at an agency
of the Issuer within the United States nor will any payment be made by transfer
to an account in, or by mail to an address in, the United States unless pursuant
to applicable United States laws and regulations then in effect such payment can
be made without adverse tax consequences to the Issuer. Notwithstanding the
foregoing, payments in Dollars of Unregistered Securities of any series and
Coupons appertaining thereto which are payable in Dollars may be made at an
agency of the Issuer maintained in the Borough of Manhattan, The City of New
York if such payment in Dollars at each agency maintained by the Issuer outside
the United States for payment on such Unregistered Securities is illegal or
effectively precluded by exchange controls or other similar restrictions.

          The Issuer will maintain in the Borough of Manhattan, The City of
New York, an office or agency where notices and demands to or upon the Issuer in
respect of the Securities of any series, the Coupons appertaining thereto or
this Indenture may be served.

                                       26
<PAGE>
 
          The Issuer will give to the Trustee written notice of the location
of each such office or agency and of any change of location thereof. In case the
Issuer shall fail to maintain any agency required by this Section to be located
in the Borough of Manhattan, The City of New York, or shall fail to give such
notice of the location or of any change in the location of any of the above
agencies, presentations and demands may be made and notices may be served at the
Corporate Trust Office of the Trustee.

          The Issuer may from time to time designate one or more additional
offices or agencies where the Securities of a series and any Coupons
appertaining thereto may be presented for payment, where the Securities of that
series may be presented for exchange as provided in this Indenture and pursuant
to Section 2.03 and where the Registered Securities of that series may be
presented for registration of transfer as in this Indenture provided, and the
Issuer may from time to time rescind any such designation, as the Issuer may
deem desirable or expedient; provided, however, that no such designation or
rescission shall in any manner relieve the Issuer of its obligation to maintain
the agencies provided for in this Section. The Issuer will give to the Trustee
prompt written notice of any such designation or rescission thereof.

          SECTION 3.03. Appointment to Fill a Vacancy in Office of Trustee.
The Issuer, whenever necessary to avoid or fill a vacancy in the office of
Trustee, will appoint, in the manner provided in Section 6.10, a Trustee, so
that there shall at all times be a Trustee with respect to each series of
Securities hereunder.

          SECTION 3.04. Paying Agents. Whenever the Issuer shall appoint a
paying agent other than the Trustee with respect to the Securities of any
series, it will cause such paying agent to execute and deliver to the Trustee an
instrument in which such agent shall agree with the Trustee, subject to the
provisions of this Section,

          (a) that it will hold all sums received by it as such agent for
the payment of the principal of or interest on the Securities of such series
(whether such sums have been paid to it by the Issuer or by any other obligor on
the Securities of such series) in trust for the benefit of the Holders of the
Securities of such series, or Coupons appertaining thereto, if any, or of the
Trustee,

          (b) that it will give the Trustee notice of any failure by the
Issuer (or by any other obligor on the Securities of such series) to make any
payment of the principal of or interest on the Securities of such series when
the same shall be due and payable, and

                                       27
<PAGE>
 
          (c) that it will pay any such sums so held in trust by it to the
Trustee upon the Trustee's written request at any time during the continuance of
the failure referred to in clause (b) above.

          The Issuer will, on or prior to each due date of the principal of or
interest on the Securities of such series, deposit with the paying agent a sum
sufficient to pay such principal or interest so becoming due, and (unless such
paying agent is the Trustee) the Issuer will promptly notify the Trustee of any
failure to take such action.

          If the Issuer shall act as its own paying agent with respect to the
Securities of any series, it will, on or before each due date of the principal
of or interest on the Securities of such series, set aside, segregate and hold
in trust for the benefit of the Holders of the Securities of such series or the
Coupons appertaining thereto a sum sufficient to pay such principal or interest
so becoming due. The Issuer will promptly notify the Trustee of any failure to
take such action.

          Anything in this Section to the contrary notwithstanding, but
subject to Section 10.01 and to the terms of any series of Securities, the
Issuer may at any time, for the purpose of obtaining a satisfaction and
discharge with respect to one or more or all series of Securities hereunder, or
for any other reason, pay or cause to be paid to the Trustee all sums held in
trust for any such series by the Issuer or any paying agent hereunder, as
required by this Section, such sums to be held by the Trustee upon the trusts
herein contained.

          Anything in this Section to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section is subject to the
provisions of Sections 10.03 and 11.04.

          SECTION 3.05. Written Statement to Trustee. The Issuer will furnish
to the Trustee on or before March 31 in each year (beginning with March 31,
1999) a brief certificate (which need not comply with Section 11.05) from the
principal executive, financial or accounting officer of the Issuer stating that
in the course of the performance by the signer of his duties as an officer of
the Issuer he would normally have knowledge of any default or non-compliance by
the Issuer in the performance of any covenants or conditions contained in this
Indenture, stating whether or not he has knowledge of any such default or
non-compliance and, if so, specifying each such default or non-compliance of
which the signer has knowledge and the nature thereof.

          SECTION 3.06. Luxembourg Publications. In the event of the publication
of any notice pursuant to Sections 5.11, 6.08, 6.10(a), 6.11, 8.02, 10.04, 12.02
or 12.05, the party making such publication in the Borough of Manhattan, The
City

                                       28
<PAGE>
 
of New York and London shall also, to the extent that notice is required to be
given to Holders of Securities of any series by applicable Luxembourg law or
stock exchange regulation, as evidenced by an Officer's Certificate delivered to
such party, make a similar publication in Luxembourg.



                                   ARTICLE 4
        SECURITYHOLDERS LISTS AND REPORTS BY THE ISSUER AND THE TRUSTEE

          SECTION 4.01. Issuer to Furnish Trustee Information as to Names and
Addresses of Securityholders. If and so long as the Trustee shall not be the
Security registrar for the Securities of any series, the Issuer and any other
obligor on the Securities will furnish or cause to be furnished to the Trustee a
list in such form as the Trustee may reasonably require of the names and
addresses of the Holders of the Registered Securities of such series pursuant to
Section 312 of the Trust Indenture Act of 1939 (a) semi-annually not more than
15 days after each record date for the payment of interest on such Registered
Securities, as hereinabove specified, as of such record date and on dates to be
determined pursuant to Section 2.03 for non-interest bearing Registered
Securities in each year, and (b) at such other times as the Trustee may request
in writing, within thirty days after receipt by the Issuer of any such request
as of a date not more than 15 days prior to the time such information is
furnished.

          SECTION 4.02.  Preservation and Disclosure of Securityholders Lists.
[This Section intentionally left blank.]

          SECTION 4.03. Reports by the Issuer. The Issuer covenants to file
with the Trustee, within 15 days after the Issuer is required to file the same
with the Commission, copies of the annual reports and of the information,
documents, and other reports that the Issuer may be required to file with the
Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934 or pursuant to Section 314 of the Trust Indenture Act of 1939.

          SECTION 4.04. Reports by the Trustee. Any Trustee's report required
under Section 313(a) of the Trust Indenture Act of 1939 shall be transmitted on
or before May 15 in each year beginning May 15, 1998, as provided in Section
313(c) of the Trust Indenture Act of 1939, so long as any Securities are
Outstanding hereunder, and shall be dated as of a date convenient to the Trustee
no more than 60 days prior thereto.

      REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS IN THE EVENT OF DEFAULT

          SECTION 5.01. Event of Default Defined; Acceleration of Maturity;
Waiver of Default. "EVENT OF DEFAULT" with respect to Securities of any series
wherever used herein, means each one of the following events which shall have
occurred and be continuing (whatever the reason for such Event of Default and
whether it shall be voluntary or involuntary or be effected by operation of law
or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):

          (a) default in the payment of any instalment of interest upon any
of the Securities of such series as and when the same shall become due and
payable, and continuance of such default for a period of 30 days; provided,
however, that a valid extension of an interest payment period by the Issuer in
accordance with the terms of Securities of a series issued hereunder shall not
constitute a default in the payment of interest for this purpose; or

          (b) default in the payment of all or any part of the principal on
any of the Securities of such series as and when the same shall become due and
payable either at maturity, upon any redemption, by declaration or otherwise; or

          (c) failure on the part of the Issuer duly to observe or perform
any other of the covenants or agreements on the part of the Issuer in the
Securities of such series (other than a covenant or warranty in respect of the
Securities of such series a default in the performance or breach of which is
elsewhere in this Section specifically dealt with) or in this Indenture and
continued for a period of 60 days after the date on which written notice
specifying such failure, stating that such notice is a "NOTICE OF DEFAULT"
hereunder and demanding that the Issuer remedy the same, shall have been given
by registered or certified mail, return receipt requested, to the Issuer by the
Trustee, or to the Issuer and the Trustee by the Holders of at least 25% in
aggregate principal amount of the Outstanding Securities of all series affected
thereby and, if the Securities of such series are held by an MSDW Capital Trust
or a trustee of such trust and should the Trustee or such Holders of the
Outstanding Securities fail to give such notice, the holders of at least 25% in
aggregate liquidation amount of the outstanding Capital Securities of such trust
shall have the right to give such notice; or

          (d) a court having jurisdiction in the premises shall enter a
decree or order for relief in respect of the Issuer in an involuntary case under
any applicable

                                       30
<PAGE>
 
bankruptcy, insolvency or other similar law now or hereafter in effect, or
appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator
(or similar official) of the Issuer or for any substantial part of its property
or ordering the winding up or liquidation of its affairs, and such decree or
order shall remain unstayed and in effect for a period of 60 consecutive days;
or

          (e) the Issuer shall commence a voluntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or consent to the entry of an order for relief in an involuntary case
under any such law, or consent to the appointment or taking possession by a
receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar
official) of the Issuer or for any substantial part of its property, or make any
general assignment for the benefit of creditors; or

          (f) failure by the Issuer to make any payment at maturity,
including any applicable grace period, in respect of indebtedness, which term as
used herein means obligations (other than the Securities of such series or
non-recourse obligations) of, or guaranteed or assumed by, the Issuer for
borrowed money or evidenced by bonds, debentures, notes or other similar
instruments ("INDEBTEDNESS") in an amount in excess of $10,000,000 or the
equivalent thereof in any other currency or composite currency and such failure
shall have continued for a period of thirty days after written notice thereof
shall have been given by registered or certified mail, return receipt requested,
to the Issuer by the Trustee, or to the Issuer and the Trustee by the Holders of
not less than 25% in aggregate principal amount of the Outstanding Securities
(treated as one class) and, if the Securities of such series are held by an MSDW
Capital Trust or a trustee of such trust and should the Trustee or such Holders
of the Outstanding Securities fail to give such notice, the holders of at least
25% in aggregate liquidation amount of the outstanding Capital Securities of
such trust shall have the right to give such notice; or

          (g) a default with respect to any Indebtedness, which default
results in the acceleration of Indebtedness in an amount in excess of
$10,000,000 or the equivalent thereof in any other currency or composite
currency without such Indebtedness having been discharged or such acceleration
having been cured, waived, rescinded or annulled for a period of thirty days
after written notice thereof shall have been given by registered or certified
mail, return receipt requested, to the Issuer by the Trustee, or to the Issuer
and the Trustee by the Holders of not less than 25% in aggregate principal
amount of the Outstanding Securities (treated as one class) and, if the
Securities of such series are held by an MSDW Capital Trust or a trustee of such
trust and should the Trustee or such Holders of the Outstanding Securities fail
to give such notice, the holders of at

                                       31
<PAGE>
 
least 25% in aggregate liquidation amount of the outstanding Capital Securities
of such trust shall have such right; or

          (h) any other Event of Default provided in the supplemental
indenture under which such series of Securities is issued or in the form of
Security for such series;

provided that if any such failure, default or acceleration referred to in
clauses (f) or (g) above shall cease or be cured, waived, rescinded or annulled,
then the Event of Default hereunder by reason thereof shall be deemed likewise
to have been thereupon cured.

          If an Event of Default described in clauses (a), (b), (c) or (h) (if
the Event of Default under clause (c) or (h), as the case may be, is with
respect to less than all series of Securities then Outstanding) occurs and is
continuing, then, and in each and every such case, except for any series of
Securities the principal of which shall have already become due and payable,
either the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Securities of each such affected series then Outstanding hereunder
(voting as a single class) or, if the Securities of such series are held by an
MSDW Capital Trust or a trustee of such trust and should the Trustee or such
Holders of the Outstanding Securities fail to make the declaration referred to
below, the holders of at least 25% in aggregate liquidation amount of the
outstanding Capital Securities of such trust (voting as a separate class), by
notice in writing to the Issuer (and to the Trustee if given by Securityholders
or the holders of Capital Securities), may declare the entire principal (or, if
the Securities of any such affected series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of such series) of all Securities of all such affected series or of such
series held by an MSDW Capital Trust, as the case may be, and the interest
accrued thereon, if any, to be due and payable immediately, and upon any such
declaration, the same shall become immediately due and payable. If an Event of
Default described in clause (c) or (h) (if the Event of Default under clause (c)
or (h), as the case may be, is with respect to all series of Securities then
Outstanding), (d), (e), (f) or (g) occurs and is continuing, then and in each
and every such case, unless the principal of all the Securities shall have
already become due and payable, either the Trustee or the Holders of not less
than 25% in aggregate principal amount of all the Securities then Outstanding
hereunder (treated as one class), or, if the Securities of any such series are
held by an MSDW Capital Trust or a trustee of such trust and should the Trustee
or such Holders of the Outstanding Securities fail to make the declaration
referred to below, the Holders of at least 25% in aggregate liquidation amount
of the outstanding Capital Securities of such trust (treated as a separate
class), by notice in writing to the Issuer (and to the Trustee if given by
Securityholders or the

                                       32
<PAGE>
 
holders of Capital Securities), may declare the entire principal (or, if any
Securities are Original Issue Discount Securities, such portion of the principal
as may be specified in the terms thereof) of all the Securities then Outstanding
or of such series held by an MSDW Capital Trust, as the case may be, and
interest accrued thereon, if any, to be due and payable immediately, and upon
any such declaration the same shall become immediately due and payable.

          The foregoing provisions, however, are subject to the condition that
if, at any time after the principal (or, if the Securities are Original Issue
Discount Securities, such portion of the principal as may be specified in the
terms thereof) of the Securities of any series (or of all the Securities, as the
case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the moneys due shall have been obtained or
entered as hereinafter provided, the Issuer shall pay or shall deposit with the
Trustee a sum sufficient to pay all matured instalments of interest upon all the
Securities of each such series (or of all the Securities, as the case may be)
and the principal of any and all Securities of each such series (or of all the
Securities, as the case may be) which shall have become due otherwise than by
acceleration (with interest upon such principal and, to the extent that payment
of such interest is enforceable under applicable law, on overdue instalments of
interest, at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series (or at the respective rates of interest or Yields to Maturity of all the
Securities, as the case may be) to the date of such payment or deposit) and such
amount as shall be sufficient to cover reasonable compensation to the Trustee
and each predecessor Trustee, its agents, attorneys and counsel, and all other
expenses and liabilities incurred, and all advances made, by the Trustee and
each predecessor Trustee except as a result of negligence or bad faith, and if
any and all Events of Default under the Indenture, other than the non-payment of
the principal of Securities which shall have become due by acceleration, shall
have been cured, waived or otherwise remedied as provided herein -- then and in
every such case the Holders of a majority in aggregate principal amount of all
the Securities of each such series or of all the Securities then Outstanding, in
each case voting as a single class (except that each such series of Securities
held by an MSDW Capital Trust shall vote as a separate class), by written notice
to the Issuer and to the Trustee, may waive all defaults with respect to each
such series (or with respect to all the Securities, as the case may be) and
rescind and annul such declaration and its consequences, but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent default
or shall impair any right consequent thereon; provided however, that if the
Securities of such series are held by an MSDW Capital Trust or a trustee of such
trust, (i) such waiver or rescission and annulment shall not be effective until
the holders of a majority in aggregate liquidation amount of the Capital
Securities of such trust shall have consented to such waiver or rescission and
annulment and

                                       33
<PAGE>
 
(ii) should the Holders of the Securities of such series fail to waive such
defaults and rescind and annul such declaration and its consequences, the
holders of a majority in aggregate liquidation amount of the Capital Securities
of such trust shall have such right.

          If the Securities of a series are held by an MSDW Capital Trust or a
trustee of such trust and an Event of Default has occurred and is continuing and
such Event of Default is attributable to the failure of the Issuer to pay any
amounts payable in respect of such Securities on the date such amounts are
otherwise payable, a holder of Capital Securities of such trust may institute a
Direct Action. If the Issuer makes any payment to a holder of such Capital
Securities as a result of a Direct Action, the Issuer will have the right to
set-off any such payment against its obligation to make any corresponding
payment to such MSDW Capital Trust on such Securities.

          For all purposes under this Indenture, if a portion of the principal
of any Original Issue Discount Securities shall have been accelerated and
declared due and payable pursuant to the provisions hereof, then, from and after
such declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall be deemed, for
all purposes hereunder, to be such portion of the principal thereof as shall be
due and payable as a result of such acceleration, and payment of such portion of
the principal thereof as shall be due and payable as a result of such
acceleration, together with interest, if any, thereon and all other amounts
owing thereunder, shall constitute payment in full of such Original Issue
Discount Securities.

          SECTION 5.02. Collection of Indebtedness by Trustee; Trustee May
Prove Debt. The Issuer covenants that (a) in case default shall be made in the
payment of any instalment of interest on any of the Securities of any series
when such interest shall have become due and payable, and such default shall
have continued for a period of 30 days or (b) in case default shall be made in
the payment of all or any part of the principal of any of the Securities of any
series when the same shall have become due and payable, whether upon maturity of
the Securities of such series or upon any redemption or by declaration or
otherwise -- then upon demand of the Trustee, the Issuer will pay to the Trustee
for the benefit of the Holders of the Securities of such series the whole amount
that then shall have become due and payable on all Securities of such series,
and such Coupons, for principal or interest, as the case may be (with interest
to the date of such payment upon the overdue principal and, to the extent that
payment of such interest is enforceable under applicable law, on overdue
instalments of interest at the same rate as the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) specified in the
Securities of such series); and in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses

                                       34
<PAGE>
 
of collection, including reasonable compensation to the Trustee and each
predecessor Trustee, their respective agents, attorneys and counsel, and any
expenses and liabilities incurred, and all advances made, by the Trustee and
each predecessor Trustee except as a result of its negligence or bad faith.

          Until such demand is made by the Trustee, the Issuer may pay the
principal of and interest on the Securities of any series to the Holders,
whether or not the Securities of such series be overdue.

          In case the Issuer shall fail forthwith to pay such amounts upon
such demand, the Trustee, in its own name and as trustee of an express trust,
shall be entitled and empowered to institute any action or proceedings at law or
in equity for the collection of the sums so due and unpaid, and may prosecute
any such action or proceedings to judgment or final decree, and may enforce any
such judgment or final decree against the Issuer or other obligor upon the
Securities and collect in the manner provided by law out of the property of the
Issuer or other obligor upon the Securities, wherever situated the moneys
adjudged or decreed to be payable.

          In case there shall be pending proceedings relative to the Issuer or
any other obligor upon the Securities under Title 11 of the United States Code
or any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor, or in case
of any other comparable judicial proceedings relative to the Issuer or other
obligor upon the Securities, or to the creditors or property of the Issuer or
such other obligor, 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
pursuant to the provisions of this Section, shall be entitled and empowered, by
intervention in such proceedings or otherwise:

          (a) to file and prove a claim or claims for the whole amount of
principal and interest (or, if the Securities of any series are Original Issue
Discount Securities, such portion of the principal amount as may be specified in
the terms of such series) owing and unpaid in respect of the Securities of any
series, and to file such other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
reasonable compensation to the Trustee and each predecessor Trustee, and their
respective agents, attorneys and counsel, and for reimbursement of all expenses
and liabilities incurred, and all advances made, by the Trustee and each
predecessor Trustee, except as a result of negligence or bad faith) and of the
Securityholders allowed in any judicial

                                       35
<PAGE>
 
proceedings relative to the Issuer or other obligor upon the Securities, or to
the creditors or property of the Issuer or such other obligor,

          (b) unless prohibited by applicable law and regulations, to vote
on behalf of the holders of the Securities of any series in any election of a
trustee or a standby trustee in arrangement, reorganization, liquidation or
other bankruptcy or insolvency proceedings or person performing similar
functions in comparable proceedings, and

          (c) to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute all amounts received with
respect to the claims of the Securityholders and of the Trustee on their behalf;
and any trustee, receiver, or liquidator, custodian or other similar official is
hereby authorized by each of the Securityholders to make payments to the
Trustee, and, in the event that the Trustee shall consent to the making of
payments directly to the Securityholders, to pay to the Trustee such amounts as
shall be sufficient to cover reasonable compensation to the Trustee, each
predecessor Trustee and their respective agents, attorneys and counsel, and all
other expenses and liabilities incurred, and all advances made, by the Trustee
and each predecessor Trustee except as a result of negligence or bad faith.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities of any series or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Securityholder in any such proceeding except, as aforesaid, to vote for the
election of a trustee in bankruptcy or similar person.

          All rights of action and of asserting claims under this Indenture,
or under any of the Securities of any series or Coupons appertaining to such
Securities, may be enforced by the Trustee without the possession of any of the
Securities of such series or Coupons appertaining to such Securities or the
production thereof on any trial or other proceedings relative thereto, and any
such action or proceedings instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment, subject to
the payment of the expenses, disbursements and compensation of the Trustee, each
predecessor Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Holders of the Securities or Coupons appertaining to such
Securities in respect of which such action was taken.

          In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the

                                       36
<PAGE>
 
Trustee shall be a party), the Trustee shall be held to represent all the
Holders of the Securities or Coupons appertaining to such Securities in respect
to which such action was taken and it shall not be necessary to make any Holders
of such Securities or Coupons appertaining to such Securities parties to any
such proceedings.

          SECTION 5.03. Applications of Proceeds. Any moneys collected by the
Trustee pursuant to this Article in respect of any series shall, subject to the
subordination provisions hereof, be applied in the following order at the date
or dates fixed by the Trustee and, in case of the distribution of such moneys on
account of principal or interest, upon presentation of the several Securities
and Coupons appertaining to such Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities of such series in reduced principal amounts in exchange for the
presented Securities of like series if only partially paid, or upon surrender
thereof if fully paid:

              FIRST: To the payment of costs and expenses applicable
          to such series in respect of which monies have been collected,
          including reasonable compensation to the Trustee and each
          predecessor Trustee and their respective agents and attorneys and of
          all expenses and liabilities incurred, and all advances made, by the
          Trustee and each predecessor Trustee except as a result of
          negligence or bad faith;

              SECOND: In case the principal of the Securities of such
          series in respect of which moneys have been collected shall not have
          become and be then due and payable, to the payment of interest on
          the Securities of such series in default in the order of the
          maturity of the instalments of such interest, with interest (to the
          extent that such interest has been collected by the Trustee) upon
          the overdue instalments of interest at the same rate as the rate of
          interest or Yield to Maturity (in the case of Original Issue
          Discount Securities) specified in such Securities, such payments to
          be made ratably to the persons entitled thereto, without
          discrimination or preference;

              THIRD: In case the principal of the Securities of such
          series in respect of which moneys have been collected shall have
          become and shall be then due and payable, to the payment of the
          whole amount then owing and unpaid upon all the Securities of such
          series for principal and interest, with interest upon the overdue
          principal, and (to the extent that such interest has been collected
          by the Trustee) upon overdue instalments of interest at the same
          rate as the rate of interest or Yield to Maturity (in the case of
          Original Issue Discount Securities) specified in the Securities of

                                       37
<PAGE>
 
          such series; and in case such moneys shall be insufficient to pay in
          full the whole amount so due and unpaid upon the Securities of such
          series, then to the payment of such principal and interest or Yield
          to Maturity, without preference or priority of principal over
          interest or Yield to Maturity, or of interest or Yield to Maturity
          over principal, or of any instalment of interest over any other
          instalment of interest, or of any Security of such series over any
          other Security of such series, ratably to the aggregate of such
          principal and accrued and unpaid interest or Yield to Maturity; and

              FOURTH: To the payment of the remainder, if any, to the Issuer or
          any other person lawfully entitled thereto.

          SECTION 5.04. Suits for Enforcement. In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

          SECTION 5.05. Restoration of Rights on Abandonment of Proceedings.
In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned for any
reason, or shall have been determined adversely to the Trustee, then and in
every such case the Issuer and the Trustee shall be restored respectively to
their former positions and rights hereunder, and all rights, remedies and powers
of the Issuer, the Trustee and the Securityholders and any rights of holders of
Capital Securities to institute a Direct Action shall continue as though no such
proceedings had been taken.

          SECTION 5.06. Limitations on Suits by Securityholder. No Holder of
any Security of any series or of any Coupon appertaining thereto shall have any
right by virtue or by availing of any provision of this Indenture to institute
any action or proceeding at law or in equity or in bankruptcy or otherwise upon
or under or with respect to this Indenture, or for the appointment of a trustee,
receiver, liquidator, custodian or other similar official or for any other
remedy hereunder, unless such Holder previously shall have given to the Trustee
written notice of default and of the continuance thereof, as hereinbefore
provided, and unless also the Holders of not less than 25% in aggregate
principal amount of the Securities of each affected series then Outstanding
(treated as a single class) shall have made written request upon the Trustee to
institute such action or proceedings in its own name as trustee

                                       38
<PAGE>
 
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses and liabilities to be incurred therein
or thereby and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity shall have failed to institute any such action or
proceeding and no direction inconsistent with such written request shall have
been given to the Trustee pursuant to Section 5.09; it being understood and
intended, and being expressly covenanted by the taker and Holder of every
Security or Coupon with every other taker and Holder and the Trustee, that no
one or more Holders of Securities of any series or Coupons appertaining to such
Securities shall have any right in any manner whatever by virtue or by availing
of any provision of this Indenture to affect, disturb or prejudice the rights of
any other such Holder of Securities or Coupons appertaining to such Securities,
or to obtain or seek to obtain priority over or preference to any other such
Holder or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Holders of
Securities of the applicable series and Coupons appertaining to such Securities.
For the protection and enforcement of the provisions of this Section, each and
every Securityholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

          SECTION 5.07. Unconditional Right of Securityholders to Institute
Certain Suits. Notwithstanding any other provision in this Indenture and any
provision of any Security, the right of any Holder of any Security or Coupon to
receive payment of the principal of and interest on such Security or Coupon on
or after the respective due dates expressed in such Security or Coupon, or to
institute suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such
Holder; provided however, that if a series of Securities is held by an MSDW
Capital Trust, the Holder of such Securities shall not give such consent without
the consent of each holder of the Capital Securities of such trust.
Notwithstanding the foregoing, nothing in this Section shall be deemed to impair
the right of any holder of Capital Securities to institute a Direct Action.

          SECTION 5.08. Powers and Remedies Cumulative; Delay or Omission Not
Waiver of Default; Restoration of Rights and Remedies. Except as provided in
Section 5.06, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders of Securities or Coupons or to holders of the Capital
Securities 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.

                                       39
<PAGE>
 
          No delay or omission of the Trustee or of any Holder of Securities
or Coupons or of any holder of Capital Securities to exercise any right or power
accruing upon any Event of Default occurring and continuing as aforesaid shall
impair any such right or power or shall be construed to be a waiver of any such
Event of Default or an acquiescence therein; and, subject to Section 5.06, every
power and remedy given by this Indenture or by law to the Trustee or to the
Holders of Securities or Coupons or to holders of Capital Securities may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Holders of Securities or Coupons or by the holders of Capital
Securities.

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

          SECTION 5.09. Control by Holders of Securities. The Holders of a
majority in aggregate principal amount of the Securities of each series affected
(with all such series voting as a single class) at the time Outstanding 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 by
this Indenture; provided that such direction shall not be otherwise than in
accordance with law and the provisions of this Indenture and provided further
that (subject to the provisions of Section 6.01) the Trustee shall have the
right to decline to follow any such direction if the Trustee, being advised by
counsel, shall determine that the action or proceeding so directed may not
lawfully be taken or if the Trustee in good faith by its board of directors, the
executive committee, or a trust committee of directors or Responsible Officers
of the Trustee shall determine that the action or proceedings so directed would
involve the Trustee in personal liability or if the Trustee in good faith shall
so determine that the actions or forebearances specified in or pursuant to such
direction would be unduly prejudicial to the interests of Holders of the
Securities of all series so affected not joining in the giving of said
direction, it being understood that (subject to Section 6.01) the Trustee shall
have no duty to ascertain whether or not such actions or forebearances are
unduly prejudicial to such Holders.

                                       40
<PAGE>
 
          Nothing in this Indenture shall impair the right of the Trustee in
its discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction or directions by Securityholders.

          SECTION 5.10. Waiver of Past Defaults. Prior to the acceleration of
the maturity of any Securities as provided in Section 5.01, the Holders of a
majority in aggregate principal amount of the Securities of all series at the
time Outstanding with respect to which an Event of Default shall have occurred
and be continuing (voting as a single class) may on behalf of the Holders of all
such Securities waive any past default or Event of Default described in Section
5.01 and its consequences, except a default in respect of a covenant or
provision hereof which cannot be modified or amended without the consent of the
Holder of each Security affected; provided, that if the Securities of such
series are held by an MSDW Capital Trust or a trustee of such trust, such waiver
shall not be effective as to such Securities unless the holders of at least a
majority in aggregate liquidation amount of the Capital Securities of such trust
shall have consented to such waiver; provided further, that if the consent of
the Holder of each Outstanding Security of such series is required, such waiver
shall not be effective unless each holder of the Capital Securities of such
trust shall have consented to such waiver. In the case of any such waiver, the
Issuer, the Trustee, the Holders of all such Securities and the holders of any
Capital Securities shall be restored to their former positions and rights
hereunder, respectively; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

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

          SECTION 5.11. Trustee to Give Notice of Default, But May Withhold in
Certain Circumstances. The Trustee shall, within ninety days after the
occurrence of a default with respect to the Securities of any series, give
notice of all defaults with respect to that series known to the Trustee (a) if
any Unregistered Securities of that series are then Outstanding, to the Holders
thereof, by publication at least once in an Authorized Newspaper in the Borough
of Manhattan, The City of New York and at least once in an Authorized Newspaper
in London (and, if required by Section 3.06, at least once in an Authorized
Newspaper in Luxembourg) and (b) by mail to all Holders of Registered Securities
of such series and to such other Holders of Securities as have, within two years
preceding such transmission, filed their names and addresses with the Trustee
for that purpose, unless in each case such defaults shall have been cured before
the mailing or publication of such notice (the term "DEFAULTS" for the purpose
of this Section being hereby defined to

                                       41
<PAGE>
 
mean any event or condition which is, or with notice or lapse of time or both
would become, an Event of Default); provided that, except in the case of default
in the payment of the principal of or interest on any of the Securities of such
series, or in the payment of any sinking fund instalment on such series, the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee, or a trust committee of directors
or trustees and/or Responsible Officers of the Trustee in good faith determines
that the withholding of such notice is in the interests of the Securityholders
of such series.

          SECTION 5.12. Right of Court to Require Filing of Undertaking to Pay
Costs. All parties to this Indenture agree, and each Holder of any Security or
Coupon 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
Trustee, to any suit instituted by any Securityholder or group of
Securityholders of any series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such series, or, in the case of
any suit relating to or arising under clause (c) or (h) of Section 5.01 (if the
suit relates to Securities of more than one but less than all series), 10% in
aggregate principal amount of Securities then Outstanding and affected thereby,
or in the case of any suit relating to or arising under clause (c) or (h) (if
the suit under clause (c) or (h) relates to all the Securities then
Outstanding), (d), (e), (f) or (g) of Section 5.01, 10% in aggregate principal
amount of all Securities then Outstanding, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of or
interest (including any Additional Interest) on any Security on or after the due
date expressed in such Security or any date fixed for redemption.

                            CONCERNING THE TRUSTEE

          SECTION 6.01. Duties and Responsibilities of the Trustee; During
Default; Prior to Default. With respect to the Holders of any series of
Securities issued hereunder, the Trustee, prior to the occurrence of an Event of

curing or waiving of all Events

of Default which may have occurred with respect to such series, undertakes to
perform such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default with respect to the Securities of a
series has occurred (which has not been cured or waived) the Trustee shall
exercise with respect to such series of Securities 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.

          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

          (a) prior to the occurrence of an Event of Default with respect to
the Securities of any series and after the curing or waiving of all such Events
of Default with respect to such series which may have occurred:

              (i) the duties and obligations of the Trustee with respect to the
          Securities of any series shall be determined solely by the express
          provisions of this Indenture, and the Trustee shall not be liable
          except for the performance of such duties and obligations as are
          specifically set forth in this Indenture, and no implied covenants
          or obligations shall be read into this Indenture against the
          Trustee; and

              (ii) in the absence of bad faith on the part of the Trustee, the
          Trustee may conclusively rely, as to the truth of the statements and
          the correctness of the opinions expressed therein, upon any
          statements, certificates or opinions furnished to the Trustee and
          conforming to the requirements of this Indenture; but in the case of
          any such statements, 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) the Trustee shall not be liable for any error of judgment made
in good faith by a Responsible Officer or Responsible Officers of the Trustee,
unless it shall be proved that the Trustee was negligent in ascertaining the
pertinent facts; and

          (c) 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 pursuant to Section 5.09 relating to the time, method
and place of

                                       43
<PAGE>
 
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture.

          None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

          The provisions of this Section 6.01 are in furtherance of and
subject to Section 315 of the Trust Indenture Act of 1939.

          SECTION 6.02.  Certain Rights of the Trustee.  In furtherance of and
subject to the Trust Indenture Act of 1939, and subject to Section 6.01:

          (a) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, Officer's Certificate or any other
certificate, statement, instrument, opinion, report, notice, request, consent,
order, bond, debenture, note, coupon, security or other paper or document
believed by it to be genuine and to have been signed or presented by the proper
party or parties;

          (b) any request, direction, order or demand of the Issuer
mentioned herein shall be sufficiently evidenced by an Officer's Certificate
(unless other evidence in respect thereof be herein specifically prescribed);
and any resolution of the Board of Directors may be evidenced to the Trustee by
a copy thereof certified by the secretary or an assistant secretary of the
Issuer;

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

          (d) the Trustee shall be under no obligation to exercise any of
the trusts or powers vested in it by this Indenture at the request, order or
direction of any of the Securityholders pursuant to the provisions of this
Indenture, unless such Securityholders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred therein or thereby;

                                       44
<PAGE>
 
          (e) the Trustee shall not be liable for any action taken or
omitted by it in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it by this Indenture;

          (f) prior to the occurrence of an Event of Default hereunder and
after the curing or waiving of all Events of Default, the Trustee shall not be
bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, appraisal, bond, debenture, note, coupon,
security, or other paper or document unless requested in writing so to do by the
Holders of not less than a majority in aggregate principal amount of the
Securities of all series affected then Outstanding; provided that, if the
payment within a reasonable time to the Trustee of the costs, expenses or
liabilities likely to be incurred by it in the making of such investigation is,
in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such expenses or liabilities as a condition to
proceeding; the reasonable expenses of every such investigation shall be paid by
the Issuer or, if paid by the Trustee or any predecessor Trustee, shall be
repaid by the Issuer upon demand; and

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

          SECTION 6.03. Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof. The recitals contained herein and
in the Securities, except the Trustee's certificates of authentication, shall be
taken as the statements of the Issuer, and the Trustee assumes no responsibility
for the correctness of the same. The Trustee makes no representation as to the
validity or sufficiency of this Indenture or of the Securities or Coupons. The
Trustee shall not be accountable for the use or application by the Issuer of any
of the Securities or of the proceeds thereof.

          SECTION 6.04. Trustee and Agents May Hold Securities or Coupons;
Collections, etc. The Trustee or any agent of the Issuer or the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Securities
or Coupons with the same rights it would have if it were not the Trustee or such
agent and may otherwise deal with the Issuer and receive, collect, hold and
retain collections from the Issuer with the same rights it would have if it were
not the Trustee or such agent.

                                       45

          SECTION 6.05. Moneys Held by Trustee. Subject to the provisions of
Section 11.04 hereof, all moneys received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they
were received, but need not be segregated from other funds except to the extent
required by mandatory provisions of law. Neither the Trustee nor any agent of
the Issuer or the Trustee shall be under any liability for interest on any
moneys received by it hereunder.

          SECTION 6.06. Compensation and Indemnification of Trustee and Its
Prior Claim. The Issuer covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, such compensation as the parties
shall agree in writing from time to time (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
and the Issuer covenants and agrees to pay or reimburse the Trustee and each
predecessor Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by or on behalf of it in accordance with any of
the provisions of this Indenture (including the reasonable compensation and the
expenses and disbursements of its counsel and of all agents and other persons
not regularly in its employ) except any such expense, disbursement or advance as
may arise from its negligence or bad faith. The Issuer also covenants to
indemnify the Trustee and each predecessor Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad faith
on its part, arising out of or in connection with the acceptance or
administration of this Indenture or the trusts hereunder and its duties
hereunder, including the costs and expenses of defending itself against or
investigating any claim of liability in the premises. The obligations of the
Issuer under this Section to compensate and indemnify the Trustee and each
predecessor Trustee and to pay or reimburse the Trustee and each predecessor
Trustee for expenses, disbursements and advances shall constitute additional
indebtedness hereunder and shall survive the satisfaction and discharge of this
Indenture. Such additional indebtedness shall be a senior claim to that of the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the Holders of particular
Securities or Coupons, and the Securities are hereby subordinated to such senior
claim.

          SECTION 6.07. Right of Trustee to Rely on Officer's Certificate,
etc. Subject to Sections 6.01 and 6.02, whenever in the administration of the
trusts of this Indenture the Trustee shall deem it necessary or desirable that a
matter be proved or established prior to taking or suffering or omitting any
action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may, in the absence of negligence or bad faith
on the part of the Trustee, be deemed to be conclusively proved and established
by an Officer's Certificate delivered to the Trustee, and such certificate, in
the absence

                                       46
<PAGE>
 
of negligence or bad faith on the part of the Trustee, shall be full warrant to
the Trustee for any action taken, suffered or omitted by it under the provisions
of this Indenture upon the faith thereof.

          SECTION 6.08. Indentures Not Creating Potential Conflicting Interests
for the Trustee. The following indenture is hereby specifically described for
the purposes of Section 310(b)(1) of the Trust Indenture Act of 1939: this
Indenture with respect to the Securities of any other series.

          SECTION 6.09. Persons Eligible for Appointment as Trustee. The
Trustee for each series of Securities hereunder shall at all times be a
corporation organized and doing business under the laws of the United States of
America or of any State or the District of Columbia having a combined capital
and surplus of at least $5,000,000, and which is authorized under such laws to
exercise corporate trust powers and is subject to supervision or examination by
Federal, State or District of Columbia authority. Such corporation shall have
its principal place of business in the Borough of Manhattan, The City of New
York if there be such a corporation in such location willing to act upon
reasonable and customary terms and conditions. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid 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. In case at any time the Trustee shall cease to
be eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 6.10.

          The provisions of this Section 6.09 are in furtherance of and
subject to Section 310(a) of the Trust Indenture Act of 1939.

          SECTION 6.10. Resignation and Removal; Appointment of Successor
Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed, may at
any time resign with respect to one or more or all series of Securities by
giving written notice of resignation to the Issuer and (i) if any Unregistered
Securities of a series affected are then Outstanding, by giving notice of such
resignation to the Holders thereof, by publication at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York, and at
least once in an Authorized Newspaper in London (and, if required by Section
3.06, at least once in an Authorized Newspaper in Luxembourg), (ii) if any
Unregistered Securities of a series affected are then Outstanding, by mailing
notice of such resignation to the Holders thereof who have filed their names and
addresses with the Trustee within the two years preceding the notice at such
addresses as were so furnished to the Trustee and (iii) by mailing notice of
such resignation to the Holders of then

                                       47
<PAGE>
 
Outstanding Registered Securities of each series affected at their addresses as
they shall appear on the registry books. Upon receiving such notice of
resignation, the Issuer shall promptly appoint a successor trustee or trustees
with respect to the applicable series by written instrument in duplicate,
executed by authority of the Board of Directors, one copy of which instrument
shall be delivered to the resigning Trustee and one copy to the successor
trustee or trustees. If no successor trustee shall have been so appointed with
respect to any series and have accepted appointment within 30 days after the
mailing of such notice of resignation, the resigning trustee may petition any
court of competent jurisdiction for the appointment of a successor trustee, or
any Securityholder who has been a bona fide Holder of a Security or Securities
of the applicable series for at least six months may, subject to the provisions
of Section 5.12, on behalf of himself and all others similarly situated,
petition any such court for the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

          (b) In case at any time any of the following shall occur:

              (i) the Trustee shall fail to comply with the provisions of
          Section 310(b) of the Trust Indenture Act of 1939 with respect to
          any series of Securities after written request therefor by the
          Issuer or by any Securityholder who has been a bona fide Holder of a
          Security or Securities of such series for at least six months; or

             (ii) the Trustee shall cease to be eligible in accordance with the
          provisions of Section 6.09 and Section 310(a) of the Trust Indenture
          Act of 1939 and shall fail to resign after written request therefor by
          the Issuer or by any Securityholder; or

            (iii) the Trustee shall become incapable of acting with respect to
          any series of Securities, or shall be adjudged a bankrupt or
          insolvent, or a receiver or liquidator 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, the Issuer may remove the Trustee with respect to the
applicable series of Securities and appoint a successor trustee for such series
by written instrument, in duplicate, executed by order of the Board of Directors
of the Issuer, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor trustee, or, subject to the provisions of
Section 315(e) of the Trust Indenture Act of 1939, any Securityholder who has
been a bona fide Holder of a Security or Securities of such series for at least
six

                                       48
<PAGE>
 
months may on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor trustee with respect to such series. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Trustee and appoint a successor trustee. If no successor trustee
shall have been so appointed with respect to any series and have accepted
appointment within 30 days after the mailing of such notice of removal, the
retiring trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee, or any Securityholder who has been a bona
fide Holder of a Security or Securities of the applicable series for at least
six months may, subject to the provisions of Section 5.12, on behalf of himself
and all others similarly situated, petition any such court for the appointment
of a successor trustee. Such court may thereupon, after such notice, if any, as
it may deem proper and prescribe, appoint a successor trustee.

          (c) The Holders of a majority in aggregate principal amount of the
Securities of each series at the time outstanding may at any time remove the
Trustee with respect to Securities of such series and appoint a successor
trustee with respect to the Securities of such series by delivering to the
Trustee so removed, to the successor trustee so appointed and to the Issuer the
evidence provided for in Section 7.01 of the action in that regard taken by the
Securityholders.

          (d) Any resignation or removal of the Trustee with respect to any
series and any appointment of a successor trustee with respect to such series
pursuant to any of the provisions of this Section 6.10 shall become effective
upon acceptance of appointment by the successor trustee as provided in Section
6.11.

          SECTION 6.11. Acceptance of Appointment by Successor Trustee. Any
successor trustee appointed as provided in Section 6.10 shall execute and
deliver to the Issuer and to its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee with respect to all or any applicable series shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all rights, powers, duties and obligations
with respect to such series of its predecessor hereunder, with like effect as if
originally named as trustee for such series hereunder; but, nevertheless, on the
written request of the Issuer or of the successor trustee, upon payment of its
charges then unpaid, the trustee ceasing to act shall, subject to Section 10.04,
pay over to the successor trustee all moneys at the time held by it hereunder
and shall execute and deliver an instrument transferring to such successor
trustee all such rights, powers, duties and obligations. Upon request of any
such successor trustee, the Issuer shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor
trustee all such rights and powers. Any trustee

                                       49
<PAGE>
 
ceasing to act shall, nevertheless, retain a prior claim upon all property or
funds held or collected by such trustee to secure any amounts then due it
pursuant to the provisions of Section 6.06.

          If a successor trustee is appointed with respect to the Securities
of one or more (but not all) series, the Issuer, the predecessor Trustee and
each successor trustee with respect to the Securities of any applicable series
shall execute and deliver an indenture supplemental hereto which shall contain
such provisions as shall be deemed necessary or desirable to confirm that all
the rights, powers, trusts and duties of the predecessor Trustee with respect to
the Securities of any series as to which the predecessor Trustee is not retiring
shall continue to be vested in the predecessor Trustee, and 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 under separate
indentures.

          No successor trustee with respect to any series of Securities shall
accept appointment as provided in this Section 6.11 unless at the time of such
acceptance such successor trustee shall be qualified under Section 310(b) of the
Trust Indenture Act of 1939 and eligible under the provisions of Section 6.09.

          Upon acceptance of appointment by any successor trustee as provided
in this Section 6.11, the Issuer shall give notice thereof (a) if any
Unregistered Securities of a series affected are then Outstanding, to the
Holders thereof, by publication of such notice at least once in an Authorized
Newspaper in the Borough of Manhattan, The City of New York and at least once in
an Authorized Newspaper in London (and, if required by Section 3.06, at least
once in an Authorized Newspaper in Luxembourg), (b) if any Unregistered
Securities of a series affected are then Outstanding, to the Holders thereof who
have filed their names and addresses with the Trustee within the two years
preceding the notice, by mailing such notice to such Holders at such addresses
as were so furnished to the Trustee (and the Trustee shall make such information
available to the Issuer for such purpose) and (c) to the Holders of Registered
Securities of each series affected, by mailing such notice to such Holders at
their addresses as they shall appear on the registry books. If the acceptance of
appointment is substantially contemporaneous with the resignation, then the
notice called for by the preceding sentence may be combined with the notice
called for by Section 6.10. If the Issuer fails to give such notice within ten
days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be given at the expense of the Issuer.

                                       50
<PAGE>
 
          SECTION 6.12. Merger, Conversion, Consolidation or Succession to
Business of Trustee. 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 the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided that such
corporation shall be qualified under Section 310(b) of the Trust Indenture Act
of 1939 and eligible under the provisions of Section 6.09, without the execution
or filing of any paper or any further act on the part of any of the parties
hereto, anything herein to the contrary notwithstanding.

          In case at the time such successor to the Trustee shall succeed to
the trusts created by this Indenture any of the Securities of any series shall
have been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities so authenticated; and, in case at that time any of the
Securities of any series shall not have been authenticated, any successor to the
Trustee may authenticate such Securities either in the name of any predecessor
hereunder or in the name of the successor Trustee; and in all such cases such
certificate shall have the full force which it is anywhere in the Securities of
such series or in this Indenture provided that the certificate of the Trustee
shall have; provided, that the right to adopt the certificate of authentication
of any predecessor Trustee or to authenticate Securities of any series in the
name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

          SECTION 6.13. Preferential Collection of Claims Against the Issuer.
[This Section intentionally left blank.]

          SECTION 6.14. Appointment of Authenticating Agent. As long as any
Securities of a series remain Outstanding, the Trustee may, by an instrument in
writing, appoint with the approval of the Issuer an authenticating agent (the
"Authenticating Agent") which shall be authorized to act on behalf of the
Trustee to authenticate Securities, including Securities issued upon exchange,
registration of transfer, partial redemption or pursuant to Section 2.09.
Securities of each such series authenticated by such Authenticating Agent shall
be entitled to the benefits of this Indenture and shall be valid and obligatory
for all purposes as if authenticated by the Trustee. Whenever reference is made
in this Indenture to the authentication and delivery of Securities of any series
by the Trustee or to 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 for such series and a Certificate of Authentication
executed on behalf of the Trustee by such Authenticating Agent. Such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United

                                       51
<PAGE>
 
States of America or of any State, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$5,000,000 (determined as provided in Section 6.09 with respect to the Trustee)
and subject to supervision or examination by Federal or State authority.

          Any corporation into which any 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 any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect to all series of Securities for which it served as Authenticating Agent
without the execution or filing of any paper or any further act on the part of
the Trustee or such Authenticating Agent. Any Authenticating Agent may at any
time, and if it shall cease to be eligible shall, resign by giving written
notice of resignation to the Trustee and to the Issuer.

          Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 6.14 with respect to
one or more series of Securities, the Trustee shall upon receipt of an Issuer
Order appoint a successor Authenticating Agent and the Issuer shall provide
notice of such appointment to all Holders of Securities of such series in the
manner and to the extent provided in Section 11.04. Any successor Authenticating
Agent upon acceptance of its appointment hereunder shall become vested with all
rights, powers, duties and responsibilities of its predecessor hereunder, with
like effect as if originally named as Authenticating Agent. The Issuer agrees to
pay to the Authenticating Agent for such series from time to time reasonable
compensation. The Authenticating Agent for the Securities of any series shall
have no responsibility or liability for any action taken by it as such at the
direction of the Trustee.

          Sections 6.02, 6.03, 6.04, 6.06, 6.09 and 7.03 shall be applicable
to any Authenticating Agent.



                                   ARTICLE 7

                        CONCERNING THE SECURITYHOLDERS

          SECTION 7.01. Evidence of Action Taken by Securityholders. Any
request, demand, authorization, direction, notice, consent, waiver or other
action provided by this Indenture to be given or taken by a specified percentage
in principal

                                       52
<PAGE>
 
amount of the Securityholders of any or all series or holders of Capital
Securities interested therein may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such specified percentage
of Securityholders or holders of Capital Securities in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee. Proof of execution of any instrument or of a writing appointing
any such agent shall be sufficient for any purpose of this Indenture and
(subject to Sections 6.01 and 6.02) conclusive in favor of the Trustee and the
Issuer, if made in the manner provided in this Article.

          SECTION 7.02. Proof of Execution of Instruments and of Holding of
Securities. Subject to Sections 6.01 and 6.02, the execution of any instrument
by a Securityholder or, if a series of Securities is held by an MSDW Capital
Trust, a holder of Capital Securities or, in each case, his agent or proxy may
be proved in the following manner:

          (a) The fact and date of the execution by any Holder or, if a
series of Securities is held by an MSDW Capital Trust, by any holder of Capital
Securities of any instrument may be proved by the certificate of any notary
public or other officer of any jurisdiction authorized to take acknowledgments
of deeds or administer oaths that the person executing such instruments
acknowledged to him the execution thereof, or by an affidavit of a witness to
such execution sworn to before any such notary or other such officer. Where such
execution is by or on behalf of any legal entity other than an individual, such
certificate or affidavit shall also constitute sufficient proof of the authority
of the person executing the same. The fact of the holding by any Holder or, if a
series of Securities is held by an MSDW Capital Trust, by any holder of Capital
Securities of an Unregistered Security of any series, and the identifying number
of such Security and the date of his holding the same, may be proved by the
production of such Security or by a certificate executed by any trust company,
bank, banker or recognized securities dealer wherever situated satisfactory to
the Trustee, if such certificate shall be deemed by the Trustee to be
satisfactory. Each such certificate shall be dated and shall state that on the
date thereof a Security of such series bearing a specified identifying number
was deposited with or exhibited to such trust company, bank, banker or
recognized securities dealer by the person named in such certificate. Any such
certificate may be issued in respect of one or more Unregistered Securities of
one or more series specified therein. The holding by the person named in any
such certificate of any Unregistered Securities of any series specified therein
shall be presumed to continue for a period of one year from the date of such
certificate unless at the time of any determination of such holding (i) another
certificate bearing a later date issued in respect of the same Securities shall
be produced, or (ii) the Security of such series specified in such certificate

                                       53
<PAGE>
 
shall be produced by some other person, or (iii) the Security of such series
specified in such certificate shall have ceased to be Outstanding. Subject to
Sections 6.01 and 6.02, the fact and date of the execution of any such
instrument and the amount and numbers of Securities of any series held by the
person so executing such instrument and the amount and numbers of any Security
or Securities for such series may also be proven in accordance with such
reasonable rules and regulations as may be prescribed by the Trustee for such
series or in any other manner which the Trustee for such series may deem
sufficient.

          (b) In the case of Registered Securities, the ownership of such
Securities shall be proved by the Security register or by a certificate of the
Security registrar.

          The Issuer may set a record date for purposes of determining the
identity of Holders of Registered Securities or, if a series of Securities is
held by an MSDW Capital Trust, of holders of registered Capital Securities of
any series entitled to vote or consent to any action referred to in Section
7.01, which record date may be set at any time or from time to time by notice to
the Trustee, for any date or dates (in the case of any adjournment or
reconsideration) not more than 60 days nor less than five days prior to the
proposed date of such vote or consent, and thereafter, notwithstanding any other
provisions hereof, with respect to Registered Securities of any series, only
Holders of Registered Securities or, if a series of Securities is held by an
MSDW Capital Trust, holders of registered Capital Securities of such series of
record on such record date shall be entitled to so vote or give such consent or
revoke such vote or consent.

          SECTION 7.03. Holders to Be Treated as Owners. The Issuer, the
Trustee and any agent of the Issuer or the Trustee may deem and treat the person
in whose name any Security shall be registered upon the Security register for
such series as the absolute owner of such Security (whether or not such Security
shall be overdue and notwithstanding any notation of ownership or other writing
thereon) for the purpose of receiving payment of or on account of the principal
of and, subject to the provisions of this Indenture, interest on such Security
and for all other purposes; and neither the Issuer nor the Trustee nor any agent
of the Issuer or the Trustee shall be affected by any notice to the contrary.
The Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the
Holder of any Unregistered Security and the Holder of any Coupon or, if a series
of Securities is held by an MSDW Capital Trust, the holder of any unregistered
Capital Security as the absolute owner of such Unregistered Security or Coupon
(whether or not such Unregistered Security or Coupon shall be overdue) for the
purpose of receiving payment thereof or on account thereof and for all other
purposes and neither the Issuer, the Trustee, nor any agent of the Issuer or the
Trustee shall be affected by any notice to the contrary. All such payments so
made to any such person, or upon his order, shall be valid, and, to the extent
of the sum or sums so

                                       54
<PAGE>
 
paid, effectual to satisfy and discharge the liability for moneys payable upon
any such Unregistered Security or Coupon.

          Notwithstanding the foregoing, if the Securities of such series are
held by an MSDW Capital Trust, nothing in this Section 7.03 shall be deemed to
impair the right of any holder of Capital Securities to institute a Direct
Action or to declare an Event of Default and accelerate the maturity of such
series.

          SECTION 7.04. Securities Owned by Issuer Deemed Not Outstanding. In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all series have concurred in any direction,
consent or waiver under this Indenture, Securities which are owned by the Issuer
or any other obligor on the Securities with respect to which such determination
is being made or by any person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Issuer or any other
obligor on the Securities with respect to which such determination is being made
shall be disregarded and deemed not to be Outstanding for the purpose of any
such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver
only Securities which the Trustee knows are so owned shall be so disregarded;
provided, that, if the Securities of such series are held by an MSDW Capital
Trust or a trustee of such trust, the provisions of this Section 7.04 shall not
apply. Securities so owned which have been pledged in good faith may be regarded
as Outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to such Securities and that the pledgee
is not the Issuer or any other obligor upon the Securities or any person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer or any other obligor on the Securities. In case
of a dispute as to such right, the advice of counsel shall be full protection in
respect of any decision made by the Trustee in accordance with such advice. Upon
request of the Trustee, the Issuer shall furnish to the Trustee promptly an
Officer's Certificate listing and identifying all Securities, if any, known by
the Issuer to be owned or held by or for the account of any of the
above-described persons; and, subject to Sections 6.01 and 6.02, the Trustee
shall be entitled to accept such Officer's Certificate as conclusive evidence of
the facts therein set forth and of the fact that all Securities not listed
therein are Outstanding for the purpose of any such determination.

          SECTION 7.05. Right of Revocation of Action Taken. At any time prior
to (but not after) the evidencing to the Trustee, as provided in Section 7.01,
of the taking of any action by the Holders of the percentage in aggregate
principal amount of the Securities of any or all series, as the case may be,
specified in this Indenture in connection with such action, any Holder of a
Security or, if any such series is held by an MSDW Capital Trust, any holder of
a Capital Security the

                                       55
<PAGE>
 
serial number of which is shown by the evidence to be included among the serial
numbers of the Securities the Holders of which have consented to such action
may, by filing written notice at the Corporate Trust Office and upon proof of
holding as provided in this Article, revoke such action so far as concerns such
Security. Except as aforesaid any such action taken by the Holder of any
Security shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Security and of any Securities issued in exchange or
substitution therefor or on registration of transfer thereof, irrespective of
whether or not any notation in regard thereto is made upon any such Security.
Any action taken by the Holders of the percentage in aggregate principal amount
of the Securities of any or all series, as the case may be, specified in this
Indenture in connection with such action shall be conclusively binding upon the
Issuer, the Trustee and the Holders of all the Securities affected by such
action.



                                   ARTICLE 8

                            SUPPLEMENTAL INDENTURES

          SECTION 8.01. Supplemental Indentures Without Consent of
Securityholders. The Issuer, when authorized by a resolution of its Board of
Directors (which resolution may provide general terms or parameters for such
action and may provide that the specific terms of such action may be determined
in accordance with or pursuant to an Issuer Order), and the Trustee may from
time to time and at any time enter into an indenture or indentures supplemental
hereto for one or more of the following purposes:

          (a) to convey, transfer, assign, mortgage or pledge to the Trustee
as security for the Securities of one or more series any property or assets;

          (b) to evidence the succession of another corporation to the
Issuer, or successive successions, and the assumption by the successor
corporation of the covenants, agreements and obligations of the Issuer pursuant
to Article 9;

          (c) to add to the covenants of the Issuer such further covenants,
restrictions, conditions or provisions as the Issuer and the Trustee shall
consider to be for the protection of the Holders of Securities or Coupons, and
to make the occurrence, or the occurrence and continuance, of a default in any
such additional covenants, restrictions, conditions or provisions an Event of
Default permitting the enforcement of all or any of the several remedies
provided in this Indenture as herein set forth; provided, that in respect of any
such additional covenant, restriction, condition or provision such supplemental
indenture may provide for a

                                       56
<PAGE>
 
particular period of grace after default (which period may be shorter or longer
than that allowed in the case of other defaults) or may provide for an immediate
enforcement upon such an Event of Default or may limit the remedies available to
the Trustee upon such an Event of Default or may limit the right of the Holders
of a majority in aggregate principal amount of the Securities of such series to
waive such an Event of Default;

          (d) to cure any ambiguity or to correct or supplement any
provision contained herein or in any supplemental indenture which may be
defective or inconsistent with any other provision contained herein or in any
supplemental indenture, or to make any other provisions as the Issuer may deem
necessary or desirable, provided that no such action shall adversely affect the
interests of the Holders of the Securities or Coupons;

          (e) to establish the forms or terms of Securities of any series or
of the Coupons appertaining to such Securities as permitted by Sections 2.01 and
2.03; and

          (f) to evidence and provide for the acceptance of appointment
hereunder by a successor trustee with respect to the Securities of one or more
series and to add to or change any of the provisions of this Indenture as shall
be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one trustee, pursuant to the requirements of Section
6.11.

          The Trustee is hereby authorized to join with the Issuer in the
execution of any such supplemental indenture, to make any further appropriate
agreements and stipulations which may be therein contained and to accept the
conveyance, transfer, assignment, mortgage or pledge of any property thereunder,
but the Trustee shall not be obligated to enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

          Any supplemental indenture authorized by the provisions of this
Section may be executed without the consent of the Holders of any of the
Securities at the time outstanding, notwithstanding any of the provisions of
Section 8.02.

          SECTION 8.02. Supplemental Indentures With Consent of
Securityholders. With the consent (evidenced as provided in Article 7) of the
Holders of not less than a majority in aggregate principal amount of the
Securities at the time Outstanding of all series affected by such supplemental
indenture (voting as one class), the Issuer, when authorized by a resolution of
its Board of Directors (which resolution may provide general terms or parameters
for such action and may provide that the specific terms of such action may be
determined in accordance

                                       57
<PAGE>
 
with or pursuant to an Issuer Order), and the Trustee may, from time to time and
at any time, enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or of any supplemental indenture or of
modifying in any manner the rights of the Holders of the Securities of each such
series or of the Coupons appertaining to such Securities; provided, that no such
supplemental indenture shall (a) extend the final maturity of any Security, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any amount payable on redemption thereof,
or make the principal thereof (including any amount in respect of original issue
discount), or interest thereon payable in any coin or currency other than that
provided in the Securities and Coupons or in accordance with the terms thereof,
or reduce the amount of the principal of an Original Issue Discount Security
that would be due and payable upon an acceleration of the maturity thereof
pursuant to Section 5.01 or the amount thereof provable in bankruptcy pursuant
to Section 5.02, or alter the provisions of Sections 11.11 or 11.12 or impair or
affect the right of any Securityholder to institute suit for the payment thereof
or, if the Securities provide therefor, any right of repayment at the option of
the Securityholder, in each case without the consent of the Holder of each
Security so affected, or (b) reduce the aforesaid percentage of Securities of
any series, the consent of the Holders of which is required for any such
supplemental indenture, without the consent of the Holders of each Security so
affected; provided further, that, if the Securities of such series are held by
an MSDW Capital Trust or a trustee of such trust, so long as any of the Capital
Securities of such trust remain outstanding, no such modification may be made
that adversely affects the holders of such Capital Securities in any material
respect, and no termination of this Indenture may occur, without the prior
consent of the holders of at least a majority of the aggregate liquidation
amount of the outstanding Capital Securities of such trust unless and until the
principal of such Securities and all accrued and unpaid interest thereon have
been paid in full, and none of the modifications described in clauses (a) and
(b) above may be made without the prior written consent of all the holders of
Capital Securities of such MSDW Trust. In addition, the Issuer may not amend
this Indenture to remove the rights of holders of Capital Securities of an MSDW
Capital Trust to institute a Direct Action without the prior written consent of
all the holders of Capital Securities of such trust or to remove the obligation
to obtain the consent of such holders of Capital Securities in accordance with
this Section, without the consent of the required percentage of holders of the
Capital Securities of such Trust.

            A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of Holders of Securities of such series, or of Coupons appertaining
to such

                                       58
<PAGE>
 
Securities, with respect to such covenant or provision, shall be deemed not to
affect the rights under this Indenture of the Holders of Securities of any other
series or of the Coupons appertaining to such Securities.

          Upon the request of the Issuer, accompanied by a copy of a
resolution of the Board of Directors (which resolution may provide general terms
or parameters for such action and may provide that the specific terms of such
action may be determined in accordance with or pursuant to an Issuer Order)
certified by the secretary or an assistant secretary of the Issuer authorizing
the execution of any such supplemental indenture, and upon the filing with the
Trustee of evidence of the consent of the Holders of the Securities as aforesaid
and other documents, if any, required by Section 7.01, the Trustee shall join
with the Issuer in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such supplemental
indenture.

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

          Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall give notice thereof (a) to the Holders of then Outstanding Registered
Securities of each series affected thereby, by mailing a notice thereof by
first-class mail to such Holders at their addresses as they shall appear on the
Security register, (b) if any Unregistered Securities of a series affected
thereby are then Outstanding, to the Holders thereof who have filed their names
and addresses with the Trustee within two years preceding such notice, by
mailing a notice thereof by first-class mail to such Holders at such addresses
as were so furnished to the Trustee and (c) if any Unregistered Securities of a
series affected thereby are then Outstanding, to all Holders thereof, by
publication of a notice thereof at least once in an Authorized Newspaper in the
Borough of Manhattan, The City of New York and at least once in an Authorized
Newspaper in London (and, if required by Section 3.06, at least once in an
Authorized Newspaper in Luxembourg), and in each case such notice shall set
forth in general terms the substance of such supplemental indenture. Any failure
of the Issuer to give such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture.

          SECTION 8.03. Effect of Supplemental Indenture. Upon the execution of
any supplemental indenture pursuant to the provisions hereof, this Indenture
shall be and be deemed to be modified and amended in accordance therewith and
the

                                       59
<PAGE>
 
respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Issuer and the Holders of Securities of
each series affected thereby shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

          SECTION 8.04. Documents to Be Given to Trustee. The Trustee, subject
to the provisions of Sections 6.01 and 6.02, may receive an Officer's
Certificate and an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant to this Article 8 complies with the
applicable provisions of this Indenture.

          SECTION 8.05. Notation on Securities in Respect of Supplemental
Indentures. Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article may bear a notation in form approved by the Trustee for such series as
to any matter provided for by such supplemental indenture or as to any action
taken by Securityholders. If the Issuer or the Trustee shall so determine, new
Securities of any series so modified as to conform, in the opinion of the
Trustee and the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may be prepared by the Issuer,
authenticated by the Trustee and delivered in exchange for the Securities of
such series then Outstanding.

          SECTION 8.06. Subordination Unimpaired. This Indenture may not be
amended to alter the subordination of any of the Outstanding Securities without
the written consent of each holder of Senior Indebtedness then outstanding that
would be adversely affected thereby.



                                   ARTICLE 9

                   CONSOLIDATION, MERGER, SALE OR CONVEYANCE

          SECTION 9.01. Covenant Not to Merge, Consolidate, Sell or Convey
Property Except Under Certain Conditions. The Issuer covenants that it will not
merge or consolidate with any other person or sell, lease or convey all or
substantially all of its assets to any other person, unless (a) either the
Issuer shall be the continuing corporation, or the successor corporation or the
person which acquires by sale, lease or conveyance substantially all the assets
of the Issuer (if

                                       60
<PAGE>
 
other than the Issuer) shall be a corporation organized under the laws of the
United States of America or any State thereof or the District of Columbia and
shall expressly assume the due and punctual payment of the principal of and
interest on all the Securities and Coupons, if any, according to their tenor,
and the due and punctual performance and observance of all of the covenants and
conditions of this Indenture to be performed or observed by the Issuer, by
supplemental indenture satisfactory to the Trustee, executed and delivered to
the Trustee by such corporation, and (b) the Issuer, such person or such
successor corporation, as the case may be, shall not, immediately after such
merger or consolidation, or such sale, lease or conveyance, be in default in the
performance of any such covenant or condition.

          SECTION 9.02. Successor Corporation Substituted. In case of any such
consolidation, merger, sale, lease or conveyance, and following such an
assumption by the successor corporation, such successor corporation shall
succeed to and be substituted for the Issuer, with the same effect as if it had
been named herein. Such successor corporation may cause to be signed, and may
issue either in its own name or in the name of the Issuer prior to such
succession any or all of the Securities issuable hereunder which together with
any Coupons appertaining thereto theretofore shall not have been signed by the
Issuer and delivered to the Trustee; and, upon the order of such successor
corporation, instead of the Issuer, and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver any Securities together with any Coupons appertaining thereto
which previously shall have been signed and delivered by the officers of the
Issuer to the Trustee for authentication, and any Securities which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All of the Securities so issued together with any
Coupons appertaining thereto shall in all respects have the same legal rank and
benefit under this Indenture as the Securities theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Securities
had been issued at the date of the execution hereof.

          In case of any such consolidation, merger, sale, lease or conveyance
such changes in phrasing and form (but not in substance) may be made in the
Securities and Coupons thereafter to be issued as may be appropriate.

          In the event of any such sale or conveyance (other than a conveyance
by way of lease) the Issuer or any successor corporation which shall theretofore
have become such in the manner described in this Article shall be discharged
from all obligations and covenants under this Indenture and the Securities and
may be liquidated and dissolved.

                                       61
<PAGE>
 
          SECTION 9.03. Opinion of Counsel Delivered to Trustee. The Trustee,
subject to the provisions of Sections 6.01 and 6.02, may receive an Opinion of
Counsel as conclusive evidence that any such consolidation, merger, sale, lease
or conveyance, and any such assumption, and any such liquidation or dissolution,
complies with the applicable provisions of this Indenture.

           SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS

          SECTION 10.01. Satisfaction and Discharge of Indenture. (a) If at
any time (i) the Issuer shall have paid or caused to be paid the principal of
and interest on all the Securities of any series Outstanding hereunder and all
unmatured Coupons appertaining thereto (other than Securities of such series and
Coupons appertaining thereto which have been destroyed, lost or stolen and which
have been replaced or paid as provided in Section 2.09) as and when the same
shall have become due and payable, or (ii) the Issuer shall have delivered to
the Trustee for cancellation all Securities of any series theretofore
authenticated and all unmatured Coupons appertaining thereto (other than any
Securities of such series and Coupons appertaining thereto which shall have been
destroyed, lost or stolen and which shall have been replaced or paid as provided
in Section 2.09) or (iii) in the case of any series of Securities where the
exact amount (including the currency of payment) of principal of and interest
due on which can be determined at the time of making the deposit referred to in
clause (B) below, (A) all the Securities of such series and all unmatured
Coupons appertaining thereto not theretofore delivered to the Trustee for
cancellation shall have become due and payable, or are by their terms to become
due and payable within one year or are to be called for redemption within one
year under arrangements satisfactory to the Trustee for the giving of notice of
redemption, and (B) the Issuer shall have irrevocably deposited or caused to be
deposited with the Trustee as trust funds the entire amount in cash (other than
moneys repaid by the Trustee or any paying agent to the Issuer in accordance
with Section 10.04) or, in the case of any series of Securities the payments on
which may only be made in Dollars, direct obligations of the United States of
America, backed by its full faith and credit ("U.S. GOVERNMENT OBLIGATIONS"),
maturing as to principal and interest at such times and in such amounts as will
insure the availability of cash, or a combination thereof, sufficient in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
(1) the principal and interest on all Securities of such series and

                                       62
<PAGE>
 
Coupons appertaining thereto on each date that such principal or interest is due
and payable and (2) any mandatory sinking fund payments on the dates on which
such payments are due and payable in accordance with the terms of the Indenture
and the Securities of such series; and if, in any such case, the Issuer shall
also pay or cause to be paid all other sums payable hereunder by the Issuer,
then this Indenture shall cease to be of further effect (except as to (i) rights
of registration of transfer and exchange of Securities of such Series and of
Coupons appertaining thereto and the Issuer's right of optional redemption, if
any, (ii) substitution of mutilated, defaced, destroyed, lost or stolen
Securities or Coupons, (iii) rights of holders of Securities and Coupons
appertaining thereto to receive payments of principal thereof and interest
thereon, upon the original stated due dates therefor (but not upon
acceleration), and remaining rights of the Holders to receive mandatory sinking
fund payments, if any, (iv) the rights, obligations, duties and immunities of
the Trustee hereunder, (v) the rights of the Holders of Securities of such
series and Coupons appertaining thereto as beneficiaries hereof with respect to
the property so deposited with the Trustee payable to all or any of them, and
(vi) the obligations of the Issuer under Section 3.02) and the Trustee, on
demand of the Issuer accompanied by an Officer's Certificate and an Opinion of
Counsel and at the cost and expense of the Issuer, shall execute proper
instruments acknowledging such satisfaction of and discharging this Indenture;
provided, that the rights of Holders of the Securities and Coupons to receive
amounts in respect of principal of and interest on the Securities and Coupons
held by them shall not be delayed longer than required by then-applicable
mandatory rules or policies of any securities exchange upon which the Securities
are listed. The Issuer agrees to reimburse the Trustee for any costs or expenses
thereafter reasonably and properly incurred and to compensate the Trustee for
any services thereafter reasonably and properly rendered by the Trustee in
connection with this Indenture or the Securities of such series.

          (b) The following provisions shall apply to the Securities of each
series unless specifically otherwise provided in a Board Resolution, Officer's
Certificate or indenture supplemental hereto provided pursuant to Section 2.03.
In addition to discharge of the Indenture pursuant to the next preceding
paragraph, in the case of any series of Securities the exact amounts (including
the currency of payment) of principal of and interest due on which can be
determined at the time of making the deposit referred to in clause (i) below,
the Issuer shall be deemed to have paid and discharged the entire indebtedness
on all the Securities of such a series and the Coupons appertaining thereto on
the 91st day after the date of the deposit referred to in subparagraph (i)
below, and the provisions of this Indenture with respect to the Securities of
such series and Coupons appertaining thereto shall no longer be in effect
(except as to (A) rights of registration of transfer and exchange of Securities
of such series and of Coupons appertaining thereto and the Issuer's right of
optional redemption, if any, (B) substitution of mutilated, defaced,

                                       63
<PAGE>
 
destroyed, lost or stolen Securities or Coupons, (C) rights of Holders of
Securities and Coupons appertaining thereto to receive payments of principal
thereof and interest thereon, upon the original stated due dates therefor (but
not upon acceleration), and remaining rights of the Holders to receive mandatory
sinking fund payments, if any, (D) the rights, obligations, duties and
immunities of the Trustee hereunder, (E) the rights of the Holders of Securities
of such series and Coupons appertaining thereto as beneficiaries hereof with
respect to the property so deposited with the Trustee payable to all or any of
them and (F) the obligations of the Issuer under Section 3.02) and the Trustee,
at the expense of the Issuer, shall at the Issuer's request, execute proper
instruments acknowledging the same, if

              (i) with reference to this provision the Issuer has irrevocably
          deposited or caused to be irrevocably deposited with the Trustee as
          trust funds in trust, specifically pledged as security for, and
          dedicated solely to, the benefit of the Holders of the Securities of
          such series and Coupons appertaining thereto (A) cash in an amount, or
          (B) in the case of any series of Securities the payments on which may
          only be made in Dollars, U.S. Government Obligations, maturing as to
          principal and interest at such times and in such amounts as will
          insure the availability of cash or (C) a combination thereof,
          sufficient, in the opinion of a nationally recognized firm of
          independent public accountants expressed in a written certification
          thereof delivered to the Trustee, to pay (1) the principal and
          interest on all Securities of such series and Coupons appertaining
          thereto on each date that such principal or interest is due and
          payable and (2) any mandatory sinking fund payments on the dates on
          which such payments are due and payable in accordance with the terms
          of the Indenture and the Securities of such series;

              (ii) such deposit will not result in a breach or violation of, or
          constitute a default under, any agreement or instrument to which the
          Issuer is a party or by which it is bound;

              (iii) the Issuer has delivered to the Trustee an Opinion of
          Counsel based on the fact that (x) the Issuer has received from, or
          there has been published by, the Internal Revenue Service a ruling or
          (y) since the date hereof, there has been a change in the applicable
          Federal income tax law, in either case to the effect that, and such
          opinion shall confirm that, the Holders of the Securities of such
          series and Coupons appertaining thereto will not recognize income,
          gain or loss for Federal income tax purposes as a result of such
          deposit, defeasance and discharge and will be subject to Federal
          income tax on the same amount and in the same manner and at the

                                       64
<PAGE>
 
          same times, as would have been the case if such deposit, defeasance
          and discharge had not occurred;

              (iv) the Issuer has delivered to the Trustee an Officer's
          Certificate and an Opinion of Counsel, each stating that all
          conditions precedent provided for relating to the defeasance
          contemplated by this provision have been complied with;

              (v) no event or condition shall exist that, pursuant to the
          provisions of Section 13.01, would prevent the Issuer from making
          payments of the principal of or interest on the Securities of such
          series and Coupons appertaining thereto on the date of such deposit or
          at any time during the period ending on the 91st day after the date of
          such deposit (it being understood that this condition shall not be
          deemed satisfied until the expiration of such period); and

             (vi) the Issuer has delivered to the Trustee an Opinion of Counsel
          to the effect that (x) the trust funds will not be subject to any
          rights of holders of Senior Indebtedness, including without limitation
          those arising under Article 13 of this Indenture, and (y) after the
          91st day following the deposit, the trust funds will not be subject to
          the effect of any applicable bankruptcy, insolvency, reorganization or
          similar laws affecting creditors' rights generally, except that if a
          court were to rule under any such law in any case or proceeding that
          the trust funds remained property of the Issuer, no opinion is given
          as to the effect of such laws on the trust funds except the following:
          (A) assuming such trust funds remained in the Trustee's possession
          prior to such court ruling to the extent not paid to Holders of
          Securities of such series and Coupons appertaining thereto, the
          Trustee will hold, for the benefit of such Holders, a valid and
          perfected security interest in such trust funds that is not avoidable
          in bankruptcy or otherwise, (B) such Holders will be entitled to
          receive adequate protection of their interests in such trust funds if
          such trust funds are used, and (C) no property, rights in property or
          other interests granted to the Trustee or such Holders in exchange for
          or with respect to any of such funds will be subject to any prior
          rights of holders of Senior Indebtedness, including without limitation
          those arising under Article 13 of this Indenture.

          (c) The Issuer shall be released from its obligations under
Section 9.01 with respect to the Securities of any Series, and any Coupons
appertaining thereto, Outstanding on and after the date the conditions set forth
below are satisfied (hereinafter, "COVENANT DEFEASANCE"). For this purpose, such
covenant defeasance means that, with respect to the Outstanding Securities of
any Series, the Issuer may omit to comply with and shall have no liability in
respect of any term,

                                       65
<PAGE>
 
condition or limitation set forth in such Section, whether directly or
indirectly by reason of any reference elsewhere herein to such Section or by
reason of any reference in such Section to any other provision herein or in any
other document and such omission to comply shall not constitute an Event of
Default under Section 5.01, but the remainder of this Indenture and such
Securities and Coupons shall be unaffected thereby. The following shall be the
conditions to application of this subsection (c) of this Section 10.01:

              (i) The Issuer has irrevocably deposited or caused to be deposited
          with the Trustee as trust funds in trust for the purpose of making the
          following payments, specifically pledged as security for, and
          dedicated solely to, the benefit of the holders of the Securities of
          such series and Coupons appertaining thereto, (A) cash in an amount,
          or (B) in the case of any series of Securities the payments on which
          may only be made in Dollars, U.S. Government Obligations maturing as
          to principal and interest at such times and in such amounts as will
          insure the availability of cash or (C) a combination thereof,
          sufficient, in the opinion of a nationally recognized firm of
          independent public accountants expressed in a written certification
          thereof delivered to the Trustee, to pay (1) the principal and
          interest on all Securities of such series and Coupons appertaining
          thereto and (2) any mandatory sinking fund payments on the day on
          which such payments are due and payable in accordance with the terms
          of the Indenture and the Securities of such series.

             (ii) No Event of Default or event which with notice or lapse of
          time or both would become an Event of Default with respect to the
          Securities shall have occurred and be continuing on the date of such
          deposit or, insofar as subsections 5.01(d) and 5.01(e) are concerned,
          at any time during the period ending on the 91st day after the date of
          such deposit (it being understood that this condition shall not be
          deemed satisfied until the expiration of such period).

            (iii) Such covenant defeasance shall not cause the Trustee to have a
          conflicting interest as defined in Section 6.08 and for purposes of
          the Trust Indenture Act of 1939 with respect to any securities of the
          Issuer.

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

                                       66
<PAGE>
 
              (v) Such covenant defeasance shall not cause any Securities then
          listed on any registered national securities exchange under the
          Securities Exchange Act of 1934, as amended, to be delisted.

              (vi) No event or condition shall exist that, pursuant to the
          provisions of Section 13.01, would prevent the Issuer from making
          payments of the principal of or interest on the Securities of such
          series and Coupons appertaining thereto on the date of such deposit or
          at any time during the period ending on the 91st day after the date of
          such deposit (it being understood that this condition shall not be
          deemed satisfied until the expiration of such period).

              (vii) The Issuer shall have delivered to the Trustee an Officer's
          Certificate and Opinion of Counsel to the effect that the Holders of
          the Securities of such series and Coupons appertaining thereto will
          not recognize income, gain or loss for Federal income tax purposes as
          a result of such covenant defeasance and will be subject to Federal
          income tax on the same amounts, in the same manner and at the same
          times as would have been the case if such covenant defeasance had not
          occurred.

              (viii) The Issuer shall have delivered to the Trustee an Officer's
          Certificate and an Opinion of Counsel, each stating that all
          conditions precedent provided for relating to the covenant defeasance
          contemplated by this provision have been complied with.

              (ix) The Issuer has delivered to the Trustee an Opinion of Counsel
          to the effect that (x) the trust funds will not be subject to any
          rights of holders of Senior Indebtedness, including without limitation
          those arising under Article 13 of this Indenture, and (y) after the
          91st day following the deposit, the trust funds will not be subject to
          the effect of any applicable bankruptcy, insolvency, reorganization or
          similar laws affecting creditors' rights generally, except that if a
          court were to rule under any such law in any case or proceeding that
          the trust funds remained property of the Issuer, no opinion is given
          as to the effect of such laws on the trust funds except the following:
          (A) assuming such trust funds remained in the Trustee's possession
          prior to such court ruling to the extent not paid to Holders of
          Securities of such series and Coupons appertaining thereto, the
          Trustee will hold, for the benefit of such Holders, a valid and
          perfected security interest in such trust funds that is not avoidable
          in bankruptcy or otherwise, (B) such Holders will be entitled to
          receive adequate protection of their interests in such trust funds if
          such trust funds are used, and (C) no property, rights in property or
          other interests granted to the Trustee or such Holders in exchange for
          or with

                                       67
<PAGE>
 
          respect to any of such funds will be subject to any prior rights of
          holders of Senior Indebtedness, including without limitation those
          arising under Article 13 of this Indenture.

          SECTION 10.02. Application by Trustee of Funds Deposited for Payment
of Securities. Subject to Section 10.04, all moneys deposited with the Trustee
(or other trustee) pursuant to Section 10.01 shall be held in trust and applied
by it to the payment, either directly or through any paying agent (including the
Issuer acting as its own paying agent), to the Holders of the particular
Securities of such series and of Coupons appertaining thereto for the payment or
redemption of which such moneys have been deposited with the Trustee, of all
sums due and to become due thereon for principal and interest; but such money
need not be segregated from other funds except to the extent required by law.

          SECTION 10.03. Repayment of Moneys Held by Paying Agent. In
connection with the satisfaction and discharge of this Indenture with respect to
Securities of any series, all moneys then held by any paying agent under the
provisions of this Indenture with respect to such series of Securities shall,
upon demand of the Issuer, be repaid to it or paid to the Trustee and thereupon
such paying agent shall be released from all further liability with respect to
such moneys.

          SECTION 10.04. Return of Moneys Held by Trustee and Paying Agent
Unclaimed for Two Years. Any moneys deposited with or paid to the Trustee or any
paying agent for the payment of the principal of or interest on any Security of
any series or Coupons attached thereto and not applied but remaining unclaimed
for two years after the date upon which such principal or interest shall have
become due and payable, shall, upon the written request of the Issuer and unless
otherwise required by mandatory provisions of applicable escheat or abandoned or
unclaimed property law, be repaid to the Issuer by the Trustee for such series
or such paying agent, and the Holder of the Securities of such series and of any
Coupons appertaining thereto shall, unless otherwise required by mandatory
provisions of applicable escheat or abandoned or unclaimed property laws,
thereafter look only to the Issuer for any payment which such Holder may be
entitled to collect, and all liability of the Trustee or any paying agent with
respect to such moneys shall thereupon cease; provided, however, that the
Trustee or such paying agent, before being required to make any such repayment
with respect to moneys deposited with it for any payment (a) in respect of
Registered Securities of any series, shall at the expense of the Issuer, mail by
first-class mail to Holders of such Securities at their addresses as they shall
appear on the Security register, an (b) in respect of Unregistered Securities of
any series, shall at the expense of the Issuer cause to be published once, in an
Authorized Newspaper in the Borough of Manhattan, The City of New York and once
in an Authorized Newspaper in

                                       68
<PAGE>
 
London (and if required by Section 3.06, once in an Authorized Newspaper in
Luxembourg), notice, that such moneys remain and that, after a date specified
therein, which shall not be less than thirty days from the date of such mailing
or publication, any unclaimed balance of such money then remaining will be
repaid to the Issuer.

          SECTION 10.05. Indemnity for U.S. Government Obligations. The Issuer
shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the U.S. Government Obligations deposited pursuant to
Section 10.01 or the principal or interest received in respect of such
obligations.



                                  ARTICLE 11

                           MISCELLANEOUS PROVISIONS

          SECTION 11.01. Incorporators, Stockholders, Officers and Directors
of Issuer Exempt from Individual Liability. No recourse under or upon any
obligation, covenant or agreement contained in this Indenture, or in any
Security, or because of any indebtedness evidenced thereby, shall be had against
any incorporator, as such or against any past, present or future stockholder,
officer or director, as such, of the Issuer or of any successor, either directly
or through the Issuer or any successor, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise, all such liability being expressly waived
and released by the acceptance of the Securities and the Coupons appertaining
thereto by the Holders thereof and as part of the consideration for the issue of
the Securities and the Coupons appertaining thereto.

          SECTION 11.02. Provisions of Indenture for the Sole Benefit of
Parties and Holders of Securities and Coupons. Nothing in this Indenture, in the
Securities or in the Coupons appertaining thereto, expressed or implied, shall
give or be construed to give to any person, firm or corporation, other than the
parties hereto and their successors and the holders of Senior Indebtedness and
the Holders of the Securities or Coupons, if any, any legal or equitable right,
remedy or claim under this Indenture or under any covenant or provision herein
contained, all such covenants and provisions being for the sole benefit of the
parties hereto and their successors, the holders of the Senior Indebtedness and
the Holders of the Securities or Coupons, if any.

          SECTION 11.03.  Successors and Assigns of Issuer Bound by Indenture.
All the covenants, stipulations, promises and agreements in this Indenture

                                       69
<PAGE>
 
contained by or in behalf of the Issuer shall bind its successors and assigns,
whether so expressed or not.

          SECTION 11.04. Notices and Demands on Issuer, Trustee and Holders of
Securities and Coupons. Any notice or demand which by any provision of this
Indenture is required or permitted to be given or served by the Trustee or by
the Holders of Securities or Coupons to or on the Issuer may be given or served
by being deposited postage prepaid, first-class mail (except as otherwise
specifically provided herein) addressed (until another address of the Issuer is
filed by the Issuer with the Trustee) to Morgan Stanley, Dean Witter, Discover &
Co., 1585 Broadway, New York, New York 10036, Attention: Secretary. Any notice,
direction, request or demand by the Issuer or any Holder of Securities or
Coupons to or upon the Trustee shall be deemed to have been sufficiently given
or served by being deposited postage prepaid, first-class mail (except as
otherwise specifically provided herein) addressed (until another address of the
Trustee is filed by the Trustee with the Issuer) to The Bank of New York, 101
Barclay St, Floor 31 West, New York, New York 10286, Attention: Corporate Trust
Administration.

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

          In case, by reason of the suspension of or irregularities in regular
mail service, it shall be impracticable to mail notice to the Issuer when such
notice is required to be given pursuant to any provision of this Indenture, then
any manner of giving such notice as shall be reasonably satisfactory to the
Trustee shall be deemed to be a sufficient giving of such notice.

          SECTION 11.05. Officer's Certificates and Opinions of Counsel;
Statements to Be Contained Therein. Upon any application or demand by the Issuer
to the Trustee to take any action under any of the provisions of this Indenture,
the Issuer shall furnish to the Trustee an Officer's Certificate stating that
all conditions precedent provided for in this Indenture relating to the

                                       70
<PAGE>
 
proposed action have been complied with and an Opinion of Counsel stating that
in the opinion of such counsel all such conditions precedent have been complied
with, except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to such particular application or demand, no additional
certificate or opinion need be furnished.

          Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
provided for in this Indenture shall include (a) a statement that the person
making such certificate or opinion has read such covenant or condition (b) a
brief statement as to the nature and scope of the examination or investigation
upon which the statements or opinions contained in such certificate or opinion
are based (c) a statement that, in the opinion of such person, he has made such
examination or investigation as is necessary to enable him to express an opinion
as to whether or not such covenant or condition has been complied with an (d) a
statement as to whether or not, in the opinion of such person, such condition or
covenant has been complied with.

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

          Any certificate, statement or opinion of an officer of the Issuer or
of counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Issuer, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

                                       71
<PAGE>
 
          Any certificate or opinion of any independent firm of public
accountants filed with and directed to the Trustee shall contain a statement
that such firm is independent.

          SECTION 11.06. Payments Due on Saturdays, Sundays and Holidays. If
the date of maturity of interest on or principal of the Securities of any series
or any Coupons appertaining thereto or the date fixed for redemption or
repayment of any such Security or Coupon shall not be a Business Day, then
payment of interest or principal need not be made on such date, but may be made
on the next succeeding Business Day with the same force and effect as if made on
the date of maturity or the date fixed for redemption, and no interest shall
accrue for the period after such date.

          SECTION 11.07. Conflict of Any Provision of Indenture with Trust
Indenture Act of 1939. If and to the extent that any provision of this Indenture
limits, qualifies or conflicts with the duties imposed by, or with another
provision (an "incorporated provision") included in this Indenture by operation
of, Sections 310 to 318, inclusive, of the Trust Indenture Act of 1939, such
imposed duties or incorporated provision shall control.

          SECTION 11.08. New York Law to Govern. This Indenture and each
Security and Coupon shall be deemed to be a contract under the laws of the State
of New York, and for all purposes shall be construed in accordance with the laws
of such State, except as may otherwise be required by mandatory provisions of
law.

          SECTION 11.09. Counterparts. This Indenture may be executed in any
number of counterparts, each of which shall be an original; but such
counterparts shall together constitute but one and the same instrument.

          SECTION 11.10. Effect of Headings. The Article and Section headings
herein and the Table of Contents are for convenience only and shall not affect
the construction hereof.

          SECTION 11.11. Securities in a Foreign Currency. Unless otherwise
specified in an Officer's Certificate delivered pursuant to Section 2.03 of this
Indenture with respect to a particular series of Securities, whenever for
purposes of this Indenture any action may be taken by the Holders of a specified
percentage in aggregate principal amount of Securities of all series or all
series affected by a particular action at the time Outstanding and, at such
time, there are Outstanding Securities of any series which are denominated in a
Foreign Currency, then the principal amount of Securities of such series which
shall be deemed to be Outstanding for the purpose of taking such action shall be
that amount of Dollars

                                       72
<PAGE>
 
that could be obtained for such amount at the Market Exchange Rate. For purposes
of this Section 11.11, Market Exchange Rate shall mean the noon Dollar buying
rate in New York City for cable transfers of that currency published by the
Federal Reserve Bank of New York; provided, however, in the case of ECUs, Market
Exchange Rate shall mean the rate of exchange determined by the Commission of
the European Communities (or any successor thereto) as published in the Official
Journal of the European Communities (such publication or any successor
publication, the "Journal"). If such Market Exchange Rate is not available for
any reason with respect to such currency, the Trustee shall use, in its sole
discretion and without liability on its part, such quotation of the Federal
Reserve Bank of New York or, in the case of ECUs, the rate of exchange as
published in the Journal, as of the most recent available date, or quotations
or, in the case of ECUs, rates of exchange from one or more major banks in The
City of New York or in the country of issue of the currency in question, which
for purposes of the ECU shall be Brussels, Belgium, or such other quotations or,
in the case of ECU, rates of exchange as the Trustee shall deem appropriate. The
provisions of this paragraph shall apply in determining the equivalent principal
amount in respect of Securities of a series denominated in a currency other than
Dollars in connection with any action taken by Holders of Securities pursuant to
the terms of this Indenture, including, without limitation, any determination
contemplated in Sections 5.01(f) or 5.01(g).

          All decisions and determinations of the Trustee regarding the Market
Exchange Rate or any alternative determination provided for in the preceding
paragraph shall be in its sole discretion and shall, in the absence of manifest
error, be conclusive to the extent permitted by law for all purposes and
irrevocably binding upon the Issuer and all Holders.

          SECTION 11.12. Judgment Currency. The Issuer agrees, to the fullest
extent that it may effectively do so under applicable law, that (a) if for the
purpose of obtaining judgment in any court it is necessary to convert the sum
due in respect of the principal of or interest on the Securities of any series
(the "Required Currency") into a currency in which a judgment will be rendered
(the "Judgment Currency"), the rate of exchange used shall be the rate at which
in accordance with normal banking procedures the Trustee could purchase in The
City of New York the Required Currency with the Judgment Currency on the day on
which final unappealable judgment is entered, unless such day is not a New York
Banking Day, then, to the extent permitted by applicable law, the rate of
exchange used shall be the rate at which in accordance with normal banking
procedures the Trustee could purchase in The City of New York the Required
Currency with the Judgment Currency on the New York Banking Day preceding the
day on which a final unappealable judgment is entered, and (b) its obligations
under this Indenture to make payments in the Required Currency (i) shall not be
discharged

                                       73
<PAGE>
 
or satisfied by any tender, or any recovery pursuant to any judgment (whether or
not entered in accordance with subsection (a)), in any currency other than the
Required Currency, except to the extent that such tender or recovery shall
result in the actual receipt, by the payee, of the full amount of the Required
Currency expressed to be payable in respect of such payments, (ii) shall be
enforceable as an alternative or additional cause of action for the purpose of
recovering in the Required Currency the amount, if any, by which such actual
receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the
foregoing, "New York Banking Day" means any day except a Saturday, Sunday or a
legal holiday in The City of New York or a day on which banking institutions in
The City of New York are authorized or required by law or executive order to
close.



                                  ARTICLE 12

                  REDEMPTION OF SECURITIES AND SINKING FUNDS

          SECTION 12.01. Applicability of Article. The provisions of this
Article shall be applicable to the Securities of any series which are redeemable
before their maturity or to any sinking fund for the retirement of Securities of
a series except as otherwise specified as contemplated by Section 2.03 for
Securities of such series.

          SECTION 12.02. Notice of Redemption; Partial Redemptions. Notice of
redemption to the Holders of Registered Securities of any series to be redeemed
as a whole or in part at the option of the Issuer shall be given by mailing
notice of such redemption by first class mail, postage prepaid, at least 30 days
and not more than 60 days prior to the date fixed for redemption to such Holders
of Securities of such series at their last addresses as they shall appear upon
the registry books. Notice of redemption to the Holders of Unregistered
Securities to be redeemed as a whole or in part, who have filed their names and
addresses with the Trustee within the two years preceding such notice of
redemption, shall be given by mailing notice of such redemption, by first class
mail, postage prepaid, at least 30 days and not more than 60 prior to the date
fixed for redemption, to such Holders at such addresses as were so furnished to
the Trustee (and, in the case of any such notice given by the Issuer, the
Trustee shall make such information available to the Issuer for such purpose).
Notice of redemption to all other Holders of Unregistered Securities shall be
published in an Authorized Newspaper in the Borough of Manhattan, The City of
New York and in an Authorized Newspaper in London (and, if required by Section
3.06, in an Authorized Newspaper in

                                       74
<PAGE>
 
Luxembourg), in each case, once in each of three successive calendar weeks, the
first publication to be not less than 30 nor more than 60 days prior to the date
fixed for redemption. Any notice which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not the
Holder receives the notice. Failure to give notice by mail, or any defect in the
notice to the Holder of any Security of a series designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the
redemption of any other Security of such series.

          The notice of redemption to each such Holder shall specify the
principal amount of each Security of such series held by such Holder to be
redeemed, the date fixed for redemption, the redemption price, the place or
places of payment, that payment will be made upon presentation and surrender of
such Securities and, in the case of Securities with Coupons attached thereto, of
all Coupons appertaining thereto maturing after the date fixed for redemption,
that such redemption is pursuant to the mandatory or optional sinking fund, or
both, if such be the case, that interest accrued to the date fixed for
redemption will be paid as specified in such notice and that on and after said
date interest thereon or on the portions thereof to be redeemed will cease to
accrue. In case any Security of a series is to be redeemed in part only the
notice of redemption shall state the portion of the principal amount thereof to
be redeemed and shall state that on and after the date fixed for redemption,
upon surrender of such Security, a new Security or Securities of such series in
principal amount equal to the unredeemed portion thereof will be issued.

          The notice of redemption of Securities of any series to be redeemed
at the option of the Issuer shall be given by the Issuer or, at the Issuer's
request, by the Trustee in the name and at the expense of the Issuer.

          On or before the redemption date specified in the notice of
redemption given as provided in this Section, the Issuer will deposit with the
Trustee or with one or more paying agents (or, if the Issuer is acting as its
own paying agent, set aside, segregate and hold in trust as provided in Section
3.04) an amount of money sufficient to redeem on the redemption date all the
Securities of such series so called for redemption at the appropriate redemption
price, together with accrued interest to the date fixed for redemption. The
Issuer will deliver to the Trustee at least 70 days prior to the date fixed for
redemption an Officer's Certificate stating the aggregate principal amount of
Securities to be redeemed. In case of a redemption at the election of the Issuer
prior to the expiration of any restriction on such redemption, the Issuer shall
deliver to the Trustee, prior to the giving of any notice of redemption to
Holders pursuant to this Section, an Officer's Certificate stating that such
restriction has been complied with.

                                       75

          If less than all the Securities of a series are to be redeemed, the
Trustee shall select, in such manner as it shall deem appropriate and fair,
Securities of such Series to be redeemed in whole or in part. Securities may be
redeemed in part in multiples equal to the minimum authorized denomination for
Securities of such series or any multiple thereof. The Trustee shall promptly
notify the Issuer in writing of the Securities of such series selected for
redemption and, in the case of any Securities of such series selected for
partial redemption, the principal amount thereof to be redeemed. For all
purposes of this Indenture, unless the context otherwise requires, all
provisions relating to the redemption of Securities of any series shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

          SECTION 12.03. Payment of Securities Called for Redemption. If
notice of redemption has been given as above provided, the Securities or
portions of Securities specified in such notice shall become due and payable on
the date and at the place stated in such notice at the applicable redemption
price, together with interest accrued to the date fixed for redemption, and on
and after said date (unless the Issuer shall default in the payment of such
Securities at the redemption price, together with interest accrued to said date)
interest on the Securities or portions of Securities so called for redemption
shall cease to accrue, and the unmatured Coupons, if any, appertaining thereto
shall be void, and, except as provided in Sections 6.05 and 10.04, such
Securities shall cease from and after the date fixed for redemption to be
entitled to any benefit or security under this Indenture, and the Holders
thereof shall have no right in respect of such Securities except the right to
receive the redemption price thereof and unpaid interest to the date fixed for
redemption. On presentation and surrender of such Securities at a place of
payment specified in said notice, together with all Coupons, if any,
appertaining thereto maturing after the date fixed for redemption, said
Securities or the specified portions thereof shall be paid and redeemed by the
Issuer at the applicable redemption price, together with interest accrued
thereon to the date fixed for redemption; provided that payment of interest
becoming due on or prior to the date fixed for redemption shall be payable in
the case of Securities with Coupons attached thereto, to the Holders of the
Coupons for such interest upon surrender thereof, and in the case of Registered
Securities, to the Holders of such Registered Securities registered as such on
the relevant record date subject to the terms and provisions of Sections 2.03
and 2.07 hereof.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate of
interest or Yield to Maturity (in the case of an Original Issue Discount
Security) borne by such Security.

                                       76
<PAGE>
 
          If any Security with Coupons attached thereto is surrendered for
redemption and is not accompanied by all appurtenant Coupons maturing after the
date fixed for redemption, the surrender of such missing Coupon or Coupons may
be waived by the Issuer and the Trustee, if there be furnished to each of them
such security or indemnity as they may require to save each of them harmless.

          Upon presentation of any Security redeemed in part only, the Issuer
shall execute and the Trustee shall authenticate and deliver to or on the order
of the Holder thereof, at the expense of the Issuer, a new Security or
Securities of such series, of authorized denominations, in principal amount
equal to the unredeemed portion of the Security so presented.

          SECTION 12.04. Exclusion of Certain Securities from Eligibility for
Selection for Redemption. Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration and certificate
number in an Officer's Certificate delivered to the Trustee at least 40 days
prior to the last date on which notice of redemption may be given as being owned
of record and beneficially by, and not pledged or hypothecated by either (a) the
Issuer or (b) an entity specifically identified in such written statement as
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer.

          SECTION 12.05. Mandatory and Optional Sinking Funds. The minimum
amount of any sinking fund payment provided for by the terms of the Securities
of any series is herein referred to as a "mandatory sinking fund payment", and
any payment in excess of such minimum amount provided for by the terms of the
Securities of any series is herein referred to as an "optional sinking fund
payment". The date on which a sinking fund payment is to be made is herein
referred to as the "sinking fund payment date".

          In lieu of making all or any part of any mandatory sinking fund
payment with respect to any series of Securities in cash, the Issuer may at its
option (a) deliver to the Trustee Securities of such series theretofore
purchased or otherwise acquired (except upon redemption pursuant to the
mandatory sinking fund) by the Issuer or receive credit for Securities of such
series (not previously so credited) theretofore purchased or otherwise acquired
(except as aforesaid) by the Issuer and delivered to the Trustee for
cancellation pursuant to Section 2.10, (b) receive credit for optional sinking
fund payments (not previously so credited) made pursuant to this Section, or (c)
receive credit for Securities of such series (not previously so credited)
redeemed by the Issuer through any optional redemption provision contained in
the terms of such series. Securities so delivered or credited shall be received
or credited by the Trustee at the sinking fund redemption price specified in
such Securities.

                                       77
<PAGE>
 
          On or before the 60th day next preceding each sinking fund payment
date for any series, the Issuer will deliver to the Trustee an Officer's
Certificate (which need not contain the statements required by Section 11.05)
(a) specifying the portion of the mandatory sinking fund payment to be satisfied
by payment of cash and the portion to be satisfied by credit of Securities of
such series and the basis for such credit, (b) stating that none of the
Securities of such series has theretofore been so credited, (c) stating that no
defaults in the payment of interest or Events of Default with respect to such
series have occurred (which have not been waived or cured) and are continuing
and (d) stating whether or not the Issuer intends to exercise its right to make
an optional sinking fund payment with respect to such series and, if so,
specifying the amount of such optional sinking fund payment which the Issuer
intends to pay on or before the next succeeding sinking fund payment date. Any
Securities of such series to be credited and required to be delivered to the
Trustee in order for the Issuer to be entitled to credit therefor as aforesaid
which have not theretofore been delivered to the Trustee shall be delivered for
cancellation pursuant to Section 2.10 to the Trustee with such Officer's
Certificate (or reasonably promptly thereafter if acceptable to the Trustee).
Such Officer's Certificate shall be irrevocable and upon its receipt by the
Trustee the Issuer shall become unconditionally obligated to make all the cash
payments or payments therein referred to, if any, on or before the next
succeeding sinking fund payment date. Failure of the Issuer, on or before any
such 60th day, to deliver such Officer's Certificate and Securities specified in
this paragraph, if any, shall not constitute a default but shall constitute, on
and as of such date, the irrevocable election of the Issuer (i) that the
mandatory sinking fund payment for such series due on the next succeeding
sinking fund payment date shall be paid entirely in cash without the option to
deliver or credit Securities of such series in respect thereof and (ii) that the
Issuer will make no optional sinking fund payment with respect to such series as
provided in this Section.

          If the sinking fund payment or payments (mandatory or optional or
both) to be made in cash on the next succeeding sinking fund payment date plus
any unused balance of any preceding sinking fund payments made in cash shall
exceed $50,000 (or the equivalent thereof in any Foreign Currency) or a lesser
sum in Dollars (or the equivalent thereof in any Foreign Currency) if the Issuer
shall so request with respect to the Securities of any particular series, such
cash shall be applied on the next succeeding sinking fund payment date to the
redemption of Securities of such series at the sinking fund redemption price
together with accrued interest to the date fixed for redemption. If such amount
shall be $50,000 (or the equivalent thereof in any Foreign Currency) or less and
the Issuer makes no such request then it shall be carried over until a sum in
excess of $50,000 (or the equivalent thereof in any Foreign Currency) is
available. The Trustee shall select, in the manner provided in Section 12.02,
for redemption on such sinking fund payment date a sufficient principal amount
of Securities of such

                                       78
<PAGE>
 
series to absorb said cash, as nearly as may be, and shall (if requested in
writing by the Issuer) inform the Issuer of the serial numbers of the Securities
of such series (or portions thereof) so selected. Securities shall be excluded
from eligibility for redemption under this Section if they are identified by
registration and certificate number in an Officer's Certificate delivered to the
Trustee at least 60 days prior to the sinking fund payment date as being owned
of record and beneficially by, and not pledged or hypothecated by either (a) the
Issuer or (b) an entity specifically identified in such Officer's Certificate as
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer. The Trustee, in the name and at the expense of
the Issuer (or the Issuer, if it shall so request the Trustee in writing) shall
cause notice of redemption of the Securities of such series to be given in
substantially the manner provided in Section 12.02 (and with the effect provided
in Section 12.03) for the redemption of Securities of such series in part at the
option of the Issuer. The amount of any sinking fund payments not so applied or
allocated to the redemption of Securities of such series shall be added to the
next cash sinking fund payment for such series and, together with such payment,
shall be applied in accordance with the provisions of this Section. Any and all
sinking fund moneys held on the stated maturity date of the Securities of any
particular series (or earlier, if such maturity is accelerated), which are not
held for the payment or redemption of particular Securities of such series shall
be applied, together with other moneys, if necessary, sufficient for the
purpose, to the payment of the principal of, and interest on, the Securities of
such series at maturity.

          On or before each sinking fund payment date, the Issuer shall pay to
the Trustee in cash or shall otherwise provide for the payment of all interest
accrued to the date fixed for redemption on Securities to be redeemed on the
next following sinking fund payment date.

          The Trustee shall not redeem or cause to be redeemed any Securities
of a series with sinking fund moneys or give any notice of redemption of
Securities for such series by operation of the sinking fund during the
continuance of a default in payment of interest on such Securities or of any
Event of Default except that, where the giving of notice of redemption of any
Securities shall theretofore have been made, the Trustee shall redeem or cause
to be redeemed such Securities, provided that it shall have received from the
Issuer a sum sufficient for such redemption. Except as aforesaid, any moneys in
the sinking fund for such series at the time when any such default or Event of
Default shall occur, and any moneys thereafter paid into the sinking fund,
shall, during the continuance of such default or Event of Default, be deemed to
have been collected under Article 5 and held for the payment of all such
Securities. In case such Event of Default shall have been waived as provided in
Section 5.10 or the default cured on or before the sixtieth day preceding the
sinking fund payment date in any year, such moneys

                                       79
<PAGE>
 
shall thereafter be applied on the next succeeding sinking fund payment date in
accordance with this Section to the redemption of such Securities.



                                  ARTICLE 13

                                 SUBORDINATION

          SECTION 13.01. Securities and Coupons Subordinated to Senior
Indebtedness. The Issuer covenants and agrees, and each Holder of a Security or
Coupon, by his acceptance thereof, likewise covenants and agrees, that the
indebtedness represented by the Securities and any Coupons and the payment of
the principal of and interest on each and all of the Securities and of any
Coupons is hereby expressly subordinated, to the extent and in the manner
hereinafter set forth, in right of payment to the prior payment in full of
Senior Indebtedness.

          In the event (a) of any insolvency or bankruptcy proceedings or any
receivership, liquidation, reorganization or other similar proceedings in
respect of the Issuer or a substantial part of its property, or of any
proceedings for liquidation, dissolution or other winding up of the Issuer,
whether or not involving insolvency or bankruptcy, or (b) subject to the
provisions of Section 13.02 that (i) 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, or (ii) there shall have occurred an event
of default (other than a default in the payment of principal or interest or
other monetary amounts due and payable) in respect of any Senior Indebtedness,
as defined therein or in the instrument under which the same is outstanding,
permitting the holder or holders thereof to accelerate the maturity thereof
(with notice or lapse of time, or both), and such event of default shall have
continued beyond the period of grace, if any, in respect thereof, and, in the
cases of subclauses (i) and (ii) of this clause (b), such default or event of
default 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 5.01 and
such declaration shall not have been rescinded and annulled as provided in
Section 5.01 then:

              (i) 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 or Coupons are entitled to receive a payment
          on account of the principal of or interest on the indebtedness
          evidenced by the Securities or of the Coupons, including, without
          limitation, any payments made pursuant to Article 12;

                                       80
<PAGE>
 
              (ii) any payment by, or distribution of assets of, the Issuer of
          any kind or character, whether in cash, property or securities, to
          which the Holders of any of the Securities or Coupons 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 Coupons or to the Trustee under this
          instrument; and

              (iii) in the event that, notwithstanding the foregoing, any
          payment by, or distribution of assets of, the Issuer 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 Issuer of the Securities, shall be received by the
          Trustee or the Holders of any of the Securities or Coupons before all
          Senior Indebtedness is paid in full, or provision 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 Issuer 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 91st day
following the date of deposit of cash or, in the case of Securities payable only
in Dollars, U.S. Government Obligations pursuant to Section 10.01(b) or 10.01(c)
(provided all other conditions set out in such Section shall have been
satisfied) the funds so deposited and any interest thereon will not be subject
to any rights of holders of

                                       81
<PAGE>
 
Senior Indebtedness including, without limitation, those arising under this
Article 13.

          SECTION 13.02. Disputes with Holders of Certain Senior Indebtedness.
Any failure by the Issuer to make any payment on or perform any other obligation
under Senior Indebtedness, other than any indebtedness incurred by the Issuer or
assumed or guaranteed, directly or indirectly, by the Issuer for money borrowed
(or any deferral, renewal, extension or refunding thereof) or any indebtedness
or obligation as to which the provisions of this Section shall have been waived
by the Issuer in the instrument or instruments by which the Issuer incurred,
assumed, guaranteed or otherwise created such indebtedness or obligation, shall
not be deemed a default or event of default under Section 13.01(b) if (a) the
Issuer shall be disputing its obligation to make such payment or perform such
obligation and (b) either (i) no final judgment relating to such dispute shall
have been issued against the Issuer which is in full force and effect and is not
subject to further review, including a judgment that has become final by reason
of the expiration of the time within which a party may seek further appeal or
review, and (ii) in the event of a judgment that is subject to further review or
appeal has been issued, the Issuer shall in good faith be prosecuting an appeal
or other proceeding for review and a stay of execution shall have been obtained
pending such appeal or review.

          SECTION 13.03. Subrogation. Subject to the payment in full of all
Senior Indebtedness, the Holders of the Securities and any Coupons shall be
subrogated (equally and ratably with the holders of all obligations of the
Issuer which by their express terms are subordinated to Senior Indebtedness of
the Issuer to the same extent as the Securities are subordinated and which are
entitled to like rights of subrogation) to the rights of the holders of Senior
Indebtedness to receive payments or distributions of cash, property or
securities of the Issuer applicable to the Senior Indebtedness until all amounts
owing on the Securities and any Coupons shall be paid in full, and as between
the Issuer, its creditors other than holders of such Senior Indebtedness and the
Holders, no such payment or distribution made to the holders of Senior
Indebtedness by virtue of this Article that otherwise would have been made to
the Holders shall be deemed to be a payment by the Issuer on account of such
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 Senior Indebtedness, on the other
hand.

          SECTION 13.04. Obligation of Issuer Unconditional. Nothing contained
in this Article or elsewhere in this Indenture or in the Securities or any
Coupons is intended to or shall impair, as among the Issuer, its creditors other
than the holders of Senior Indebtedness and the Holders, the obligation of the
Issuer, which is absolute and unconditional, to pay to the Holders the principal
of and

                                       82
<PAGE>
 
interest on the Securities and the amounts owed pursuant to any Coupons 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 Issuer 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 Issuer received upon the
exercise of any such remedy.

          Upon payment or distribution of assets of the Issuer referred to in
this Article, the Trustee and the Holders shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which any such
dissolution, winding up, liquidation or reorganization proceeding affecting the
affairs of the Issuer is pending or upon a certificate of the trustee in
bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee
or agent or other person making any payment or distribution, delivered to the
Trustee or to the Holders, for the purpose of ascertaining the persons entitled
to participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Issuer, the amount thereof or payable
thereon, the amount paid or distributed thereon and all other facts pertinent
thereto or to this Article.

          SECTION 13.05. Payments on Securities and Coupons Permitted. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities or
Coupons shall affect the obligations of the Issuer to make, or prevent the
Issuer from making, payment of the principal of or interest on the Securities
and of any Coupons in accordance with the provisions hereof and thereof, except
as otherwise provided in this Article.

          SECTION 13.06. Effectuation of Subordination by Trustee. Each holder
of Securities or Coupons, by his acceptance thereof, authorizes and directs the
Trustee on his behalf to take such action as may be necessary or appropriate to
effectuate the subordination provided in this Article and appoints the Trustee
his attorney-in-fact for any and all such purposes.

          SECTION 13.07. Knowledge of Trustee. Notwithstanding the provisions
of this Article or any other provisions of this Indenture, the Trustee shall not
be charged with knowledge of the existence of any facts that would prohibit the
making of any payment of moneys to or by the Trustee, or the taking of any other
action by the Trustee, unless and until the Trustee shall have received written
notice thereof mailed or delivered to the Trustee at its Corporate Trust Office
from the Issuer, any Holder, any paying agent or the holder or representative of
any class of Senior Indebtedness; provided that if at least three Business Days

                                       83
<PAGE>
 
prior to the date upon which by the terms hereof any such moneys may become
payable for any purpose (including, without limitation, the payment of the
principal or interest on any Security or interest on any Coupon) the Trustee
shall not have received with respect to such moneys the notice provided for in
this Section, then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such moneys and to
apply the same to the purpose for which they were received and shall not be
affected by any notice to the contrary that may be received by it within three
Business Days prior to or on or after such date.

          SECTION 13.08. Trustee May Hold Senior Indebtedness. The Trustee
shall be entitled to all the rights set forth in this Article with respect to
any Senior Indebtedness at the time held by it, to the same extent as any other
holder of Senior Indebtedness, and nothing in Section 6.03 or elsewhere in this
Indenture shall deprive the Trustee of any of its rights as such holder.

          SECTION 13.09. Rights of Holders of Senior Indebtedness Not
Impaired. No right of any present or future holder of any Senior Indebtedness to
enforce the subordination herein shall at any time or in any way be prejudiced
or impaired by any act or failure to act on the part of the Issuer or by any
noncompliance by the Issuer with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

          With respect to the holders of Senior Indebtedness, (a) the duties
and obligations of the Trustee shall be determined solely by the express
provisions of this Indenture, (b) the Trustee shall not be liable except for the
performance of such duties and obligations as are specifically set forth in this
Indenture, (c) no implied covenants or obligations shall be read into this
Indenture against the Trustee and (d) the Trustee shall not be deemed to be a
fiduciary as to such holders.

          SECTION 13.10. Article Applicable to Paying Agents. In case at any
time any paying agent other than the Trustee shall have been appointed by the
Issuer and be then acting hereunder, the term "Trustee" as used in this Article
shall in such case (unless the context shall require otherwise) 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 13.07
and 13.08 shall not apply to the Issuer if it acts as its own paying agent.

          SECTION 13.11. Trustee; Compensation Not Prejudiced. Nothing in this
Article shall apply to claims of, or payments to, the Trustee pursuant to
Section 6.06.

     Morgan Stanley, Dean Witter, Discover & Co., a Delaware corporation
(together with its successors and assigns, the "ISSUER"), for value received,
hereby promises to pay to The Bank of New York, as Property Trustee (the
"PROPERTY TRUSTEE," which term includes any successor Property Trustee for MSDW
Capital Trust I) for MSDW Capital Trust I, a statutory business trust formed
under the laws of the State of Delaware (the "Issuer Trust"), or registered
assignees, the principal sum of $412, 371,150 (UNITED STATES DOLLARS FOUR
HUNDRED AND TWELVE MILLION, THREE HUNDRED SEVENTY-ONE THOUSAND, ONE HUNDRED AND
FIFTY) on February 28, 2038, such date, as it may be advanced as set forth
below, the "STATED MATURITY," and to pay interest thereon at the annual rate of
7.10% from and including March 12, 1998, until the principal hereof is paid or
duly made available for payment (except as provided below) payable quarterly in
arrears on the 28th day of February and the 30th day of May, August and
November of each year (each an "INTEREST PAYMENT DATE"), commencing May 30,
1998.

     Interest on this Debenture will accrue from and including the most recent
Interest Payment Date to which interest has been paid or duly provided for, or,
if no interest has been paid or duly provided for, from and including March 12,
1998, until, but excluding the date the principal hereof has been paid or duly
made available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, subject to certain exceptions
described herein, be paid to the person in whose name this Debenture (or one or
more predecessor Debentures) is registered at the close of business on the 15th
calendar day (whether or not a Business Day) next preceding such Interest
Payment Date (each such date a "RECORD DATE").  As used herein, "BUSINESS DAY"
means any day, other than a Saturday or Sunday, that is not a day on which
banking institutions in the City of New York are authorized or required by law
or executive order to remain closed.  A Holder of U.S. $1,000,000 or more in
aggregate principal amount of Debentures having the same Interest Payment Date,
the interest on which is payable in U.S. dollars, shall be entitled to receive
payments of interest, other than interest due at maturity or on any date of
redemption or repayment, by wire transfer of immediately available funds if
appropriate wire transfer instructions have been received by the Paying Agent in
writing not less than 15 calendar days prior to the applicable Interest Payment
Date.

     Reference is hereby made to the further provisions of this Debenture set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place, including, without
limitation, the provisions relating to the subordination of this Debenture to
the Issuer's Senior Indebtedness, as defined on the reverse hereof.

     Unless the certificate of authentication hereon has been executed by the
Trustee by manual signature, this Debenture shall not be entitled to any benefit
under the Junior Subordinated Indenture, as defined on the reverse hereof, or be
valid or obligatory for any purpose.

                             [REVERSE OF SECURITY]

   This debenture is one of a duly authorized issue of 7.10% Junior Subordinated
Debentures due February 28, 2038 (the "DEBENTURES") of the Issuer. The
Debentures are issuable under a Junior Subordinated Indenture, dated as of March
1, 1998, between Morgan Stanley, Dean Witter, Discover & Co. (the "ISSUER") and
The Bank of New York, as Trustee (the "TRUSTEE," which term includes any
successor trustee under the Junior Subordinated Indenture) (the "JUNIOR
SUBORDINATED INDENTURE"), to which Junior Subordinated Indenture reference is
hereby made for a statement of the respective rights, limitations of rights,
duties and immunities of the Issuer, the Trustee and holders of the Debentures
and the terms upon which the Debentures are, and are to be, authenticated and
delivered.  The Issuer has appointed The Bank of New York at its corporate trust
office in The City of New York as the paying agent (the "PAYING AGENT," which
term includes any additional or successor Paying Agent appointed by the Issuer)
with respect to the Debentures. To the extent not inconsistent herewith, the
terms of the Junior Subordinated Indenture are hereby incorporated by reference
herein.  Capitalized terms not otherwise defined herein have the meaning given
to such terms in the Junior Subordinated Indenture.

   This Debenture will not be subject to any sinking fund and, except as
provided below, will not be redeemable or subject to repayment at the option of
the holder prior to its Stated Maturity.

   This Debenture may be redeemed at the option of the Issuer (i) on or after
March 12, 2003 in whole at any time or in part from time to time and (ii) prior
to March 12, 2003, in whole (but not in part) at any time within 90 days
following the occurrence and continuation of a Tax Event or an Investment
Company Event (the "90-DAY PERIOD"), in each case at a redemption price equal to
the accrued and unpaid interest on the Debentures so redeemed to the date fixed
for redemption, plus 100% of the principal amount thereof (the "REDEMPTION
PRICE"). Notice of redemption shall be mailed to the registered holders of the
Debentures designated for redemption at their addresses as the same shall appear
on the Debenture register not less than 30 nor more than 60 days prior to the
date fixed for redemption, subject to all the conditions and provisions of the
Junior Subordinated Indenture. In the event of redemption of this Debenture in
part only, a new Debenture or Debentures for the amount of the unredeemed
portion hereof shall be issued in the name of the holder hereof upon the
cancellation hereof.

   The Issuer's right to redeem the Debentures under clause (ii) of the
preceding paragraph shall be subject to the condition that if at the time there
is available to the Issuer or MSDW Capital Trust I (the "ISSUER TRUST," the
terms of which have been established pursuant to the Amended and Restated Trust
Agreement dated as of March 12, 1998, among the Issuer, as depositor, The Bank
of New York, as Property Trustee, The Bank of New York (Delaware), as Delaware
Trustee and the Administrators, the "TRUST AGREEMENT") the opportunity to
eliminate, within the 90-Day Period, the Tax Event or Investment Company Event
by taking some ministerial action ("MINISTERIAL ACTION"), such as filing a form
or making an election, or pursuing some other similar reasonable measure that
will have no adverse effect on the Issuer, the Issuer Trust or the holders of
the securities issued by the Issuer Trust and will involve no material cost, the
Issuer shall pursue such measures in lieu of redemption; provided further, that
the Issuer shall have no right to redeem the Debentures

                                       4
<PAGE>
 
while the Issuer Trust is pursuing any Ministerial Action pursuant to the Trust
Agreement.  The Redemption Price shall be paid prior to 12:00 noon, New York
time, on the date of such redemption or such earlier time as the Issuer
determines; provided, that the Issuer shall deposit with the Trustee an amount
sufficient to pay the Redemption Price prior to the redemption date.

   In addition, if a Tax Event occurs, then the Issuer will have the right prior
to the termination of the Issuer Trust, to advance the Stated Maturity of this
Debenture to the minimum extent required in order to allow for the payments of
interest in respect this Debenture to continue to be tax deductible, but in no
event shall the resulting maturity of this Debenture be less than 15 years from
the date of original issuance thereof.  The Stated Maturity shall be advanced
only if, in the opinion of counsel to the Issuer, experienced in such matters,
(a) after advancing the Stated Maturity, interest paid on this Debenture will be
deductible for United States federal income tax purposes and (b) advancing the
Stated Maturity will not result in a taxable event to the holders of the Capital
Securities.

   The term "TAX EVENT" means the receipt by the Issuer Trust of an opinion of
counsel to the Issuer experienced in such matters, who shall not be an officer
or employee of the Issuer or any of its affiliates, to the effect that, as a
result of any amendment to, or change (including any announced prospective
change) in, the laws (or any regulations thereunder) of the United States or any
political subdivision or taxing authority thereof or therein, or as a result of
any official or administrative pronouncement or action or judicial decision
interpreting or applying such laws or regulations, which amendment or change is
effective or which pronouncement, action or decision is announced on or after
the date of issuance of Capital Securities of the Issuer Trust, there is more
than an insubstantial risk that (i) the Issuer Trust is, or will be within 90
days of the delivery of such opinion, subject to United States federal income
tax with respect to income received or accrued on the Debentures, (ii) interest
payable by the Issuer on the Debentures is not, or within 90 days of the
delivery of such opinion will not be, deductible by the Issuer, in whole or in
part, for United States federal income tax purposes or (iii) the Issuer Trust
is, or will be within 90 days of the delivery of the opinion, subject to more
than a de minimis amount of other taxes, duties or other governmental charges.

"INVESTMENT COMPANY EVENT" means the receipt by the Issuer Trust of an opinion
of counsel to the Issuer experienced in such matters, who shall not be an
officer or employee of the Issuer or any of its affiliates, to the effect that,
as a result of the occurrence of a change in law or regulation or a written
change (including any announced prospective change) in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority, there is more than an insubstantial risk that
the Issuer Trust is or will be considered an "investment company" that is
required to be registered under the Investment Company Act of 1940, as amended
(the "Investment Company Act"), which change or prospective change becomes
effective or would become effective, as the case may be, on or after the date of
the issuance of the Capital Securities of the Issuer Trust.

   Interest payments on this Debenture will include interest accrued to but
excluding the Interest Payment Dates or the Stated Maturity (or any earlier
redemption or repayment date), as the case may be.  Interest payments for this
Debenture will be computed and paid on the basis of a 360-day year

                                       5
<PAGE>
 
of twelve 30-day months and the actual days elapsed in a partial month in such
period.  The amount of interest payable for any full interest period will be
computed by dividing the rate per annum by four.  Accrued interest that is not
paid on the applicable Interest Payment Date will bear additional interest on
the amount thereof at the rate per annum of 7.10% (the "COUPON RATE"),
compounded quarterly and computed on the basis of a 360-day year of twelve 30-
day months and the actual days elapsed in a partial month in such period.  The
amount of additional interest payable for any full interest period will be
computed by dividing the rate per annum by four.  The term "interest' as used
herein includes quarterly interest payments, interest on quarterly interest
payments not paid on the applicable Interest Payment Date and Additional Sums
(as defined below), as applicable.

   If any Interest Payment Date or the Stated Maturity (or any redemption or
repayment date) does not fall on a Business Day, payment of interest, premium,
if any, or principal otherwise payable on such date need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the Interest Payment Date or at the Stated Maturity
(or any redemption or repayment date), and no interest on such payment shall
accrue for the period from and after the Interest Payment Date or the Stated
Maturity (or any redemption or repayment date) to such next succeeding Business
Day.

   The Junior Subordinated Indenture provides that, (a) if an Event of Default
(as defined in the Junior  Subordinated Indenture) due to the default in payment
of principal of, premium, if any, or interest on, any series of debt securities
issued under the Junior Subordinated Indenture, including the series of
Debentures of which this Debenture forms a part, or due to the default in the
performance or breach of any other covenant or warranty of the Issuer applicable
to the debt securities of such series but not applicable to all outstanding debt
securities issued under the Junior Subordinated Indenture shall have occurred
and be continuing, either the Trustee or the holders of not less than 25% in
principal amount of the debt securities of each affected series (voting as a
single class) may then declare the principal of all debt securities of all such
series and interest accrued thereon to be due and payable immediately and (b) if
an Event of Default due to a default in the performance of any other of the
covenants or agreements in the Junior Subordinated Indenture applicable to all
outstanding debt securities issued thereunder, including this Debenture, or due
to certain events of bankruptcy, insolvency and reorganization of the Issuer,
shall have occurred and be continuing, either the Trustee or the holders of not
less than 25% in principal amount of all debt securities issued under the Junior
Subordinated Indenture then outstanding (treated as one class) may declare the
principal of all such debt securities and interest accrued thereon to be due and
payable immediately, but upon certain conditions such declarations may be
annulled and past defaults may be waived (except a continuing default in payment
of principal (or premium, if any) or interest on such debt securities) by the
holders of a majority in principal amount of the debt securities of all affected
series then outstanding.  Deferral of any due date for the payment of interest
in connection with an Extension Period (as defined herein) does not constitute
an Event of Default.

   So long as no Event of Default has occurred and is continuing, the Issuer
shall have the right at any time, and from time to time, during the term of the
Debentures to defer payments of interest by extending the interest payment
period of this Debenture for a period not exceeding 20 consecutive quarters (the
"EXTENSION PERIOD"), during which Extension Period no interest shall be due and

                                       6
<PAGE>
 
payable; provided, that no Extension Period may extend beyond the Stated
Maturity.  Interest, the payment of which has been deferred because of the
extension of the interest payment period pursuant to this paragraph, will bear
interest thereon at the Coupon Rate compounded quarterly for each quarter of the
Extension Period and computed on the basis of a 360-day year of twelve 30-day
months and the actual days elapsed in a partial month in such period
("ADDITIONAL INTEREST").  The Coupon Rate payable for any full interest period
will be computed by dividing the rate per annum by four.  At the end of the
Extension Period, the Issuer shall pay all interest accrued and unpaid on this
Debenture, including any Additional Sums and Additional Interest (together,
"DEFERRED INTEREST") that shall be payable to the Holders of this Debenture in
whose names this Debenture is registered in the Securities Register on the first
Record Date after the end of the Extension Period. Before the termination of any
Extension Period, the Issuer may further extend such period; provided, that such
period together with all such further extensions thereof shall not exceed 20
consecutive quarters, or extend beyond the Stated Maturity.  In the event that
the Stated Maturity is advanced to a date prior to the end of an Extension
Period, such Extension Period shall be deemed to end on such date or such
earlier date as may be determined by the Issuer.  In the event that any
Debentures are called for redemption on a date prior to the end of an Extension
Period, with respect to such Debentures, such Extension Period shall be deemed
to end on such date or such earlier date as may be determined by the Issuer.
Upon the termination of any Extension Period and upon the payment of all
Deferred Interest then due, the Issuer may commence a new Extension Period,
subject to the foregoing requirements.  No interest shall be due and payable
during an Extension Period, except at the end thereof, but the Issuer may prepay
at any time all or any portion of the interest accrued during an Extension
Period.

   If the Property Trustee (as defined in the Trust Agreement) is the only
Holder of the Debentures at the time the Issuer selects an Extension Period, the
Issuer shall give written notice to the Issuer Trustees (as defined in the Trust
Agreement) of its selection of such Extension Period at least 30 calendar days
prior to the date the Distributions (as defined in the Trust Agreement) on the
Trust Securities (as defined in the Trust Agreement) would have been payable but
for the election to begin such Extension Period.

   If the Property Trustee is not the only Holder, or is not itself the Holder,
of the Debentures at the time the Issuer selects an Extension Period, the Issuer
shall give the Holders of the Debentures and the Trustee written notice of its
selection of such Extension Period at least 10 Business Days before the earlier
of the next succeeding Interest Payment Date or  the date the Issuer is required
to give notice of the record or payment date of such interest payment to Holders
of the Debentures.

   The Issuer covenants that it will not (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Issuer's capital stock or (ii) make any payment of
principal of or interest or premium, if any, on or repay, repurchase or redeem
any debt securities of the Issuer that rank pari passu in all respects with or
junior in interest to the Debentures (other than (a) repurchases, redemptions or
other acquisitions of shares of capital stock of the Issuer (1) in connection
with any employment contract, benefit plan or other similar arrangement with or
for the benefit of any one or more employees, officers, directors or
consultants, (2) in connection with a dividend reinvestment or stockholder stock
purchase plan or

                                       7
<PAGE>
 
(3) in connection with the issuance of capital stock of the Issuer (or
securities convertible into or exercisable for such capital stock) as
consideration in an acquisition transaction entered into prior to the applicable
Extension Period or other event referred to below, (b) as a result of an
exchange, redemption or conversion of any class or series of the Issuer's
capital stock (or any capital stock of a subsidiary of the Issuer) for any class
or series of the Issuer's capital stock or of any class or series of the
Issuer's indebtedness for any class or series of the Issuer's capital stock, (c)
the purchase of fractional interests in shares of the Issuer's capital stock
pursuant to the conversion or exchange provisions of such capital stock or the
security being converted or exchanged, (d) any declaration of a dividend in
connection with any stockholder's rights plan, or the issuance of rights, stock
or other property under any stockholder's rights plan, or the redemption or
repurchase of rights pursuant thereto, (e) payments under the Guarantee executed
and delivered by the Issuer and The Bank of New York, as trustee, for the
benefit of the holders of any Capital Securities (as defined in the Trust
Agreement), as amended from time to time (the "GUARANTEE") or (f) any dividend
in the form of stock, warrants, options or other rights where the dividend stock
or the stock issuable upon exercise of such warrants, options or other rights is
the same stock as that on which the dividend is being paid or ranks pari passu
with or junior to such stock), if at such time (i) there has occurred any event
(a) of which the Issuer has actual knowledge that with the giving of notice or
the lapse of time, or both, would constitute an Event of Default and (b) that
the Issuer has not taken reasonable steps to cure, (ii) if the Debentures are
held by the Issuer Trust, the Issuer is in default with respect to its payment
of any obligations under the Guarantee or (iii) the Issuer has given notice of
its election of an Extension Period as provided in the Junior Subordinated
Indenture and has not rescinded such notice, or such Extension Period, or any
extension thereof, is continuing.

   If an Event of Default has occurred and is continuing and such event is
attributable to the failure of the Issuer to pay any amounts payable in respect
of the Debentures on the date such amounts are otherwise payable, a registered
holder of Capital Securities may institute a legal proceeding directly against
the Issuer for enforcement of payment to such registered holder of an amount
equal to the amount payable in respect of Debentures having a principal amount
equal to the aggregate Liquidation Amount (as defined in the Trust Agreement) of
the Capital Securities held by such registered holder (a "Direct Action").  The
Issuer shall have the right to set off any payment made to such registered
holder of Capital Securities by the Issuer in connection with a Direct Action.

   As long as any Debentures are held by the Issuer Trust, the Issuer covenants
(i) to continue to hold, directly or indirectly, 100% of the Common Securities
(as defined in the Trust Agreement), provided that certain successors that are
permitted pursuant to the Junior Subordinated Indenture may succeed to the
Issuer's ownership of the Common Securities, (ii) as holder of the Common
Securities, not to voluntarily dissolve, windup or liquidate the Issuer Trust,
other than (a) in connection with a distribution of Debentures to the holders of
the Capital Securities in liquidation of the Issuer Trust or (b) in connection
with certain mergers, consolidations or amalgamations permitted by the Trust
Agreement and (iii) to use its reasonable efforts, consistent with the terms and
provisions of the Trust Agreement, to cause the Issuer Trust to continue not to
be taxable as a corporation for United States federal income tax purposes.

                                       8

   If, and for so long as, (i) the Issuer Trust is the holder of all the
Debentures and (ii) the Issuer Trust is required to pay any additional taxes,
duties or other governmental charges as a result of a Tax Event, the Issuer will
pay as additional sums on the Debentures ("ADDITIONAL SUMS") such amounts as may
be required so that the Distributions (as defined in the Trust Agreement) paid
by the Issuer Trust will not be reduced as a result of any such additional
taxes, duties or other governmental charges.

   The Issuer, as borrower, agrees to pay all debts and other obligations (other
than with respect to the Capital Securities issued by the Issuer Trust) and all
costs and expenses of the Issuer Trust (including costs and expenses relating to
the organization of the Issuer Trust, the fees and expenses of the Issuer
Trustees (as defined in the Trust Agreement) for the Issuer Trust and the costs
and expenses relating to the operation of the Issuer Trust) and to pay any and
all taxes and all costs and expenses with respect thereto (other than United
States withholding taxes) to which the Issuer Trust might become subject.  The
foregoing obligations of the Issuer under the Debentures owned by the Issuer
Trust are for the benefit of, and shall be enforceable by, any person to whom
any such debts, obligations, costs, expenses and taxes are owed (a "CREDITOR")
whether or not such Creditor has received notice thereof.  Any such Creditor may
enforce such obligations of the Issuer directly against the Issuer, and the
Issuer irrevocably waives any right or remedy to require that any such Creditor
take any action against the Issuer Trust or any other person before proceeding
against the Issuer.  The Issuer agrees to execute any additional agreements as
may be necessary or desirable to give full effect to the foregoing.

   The provisions of Section 3.04 and Section 10.01 of the Junior Subordinated
Indenture relating to discharge, defeasance and covenant defeasance are not
applicable to this Debenture.

   This Debenture and all other obligations of the Issuer hereunder will
constitute part of the junior subordinated debt of the Issuer, will be issued
under the Junior Subordinated Indenture and will be subordinate and junior in
right of payment, to the extent and in the manner set forth in the Junior
Subordinated Indenture, to all "Senior Indebtedness" of the Issuer. The Junior
Subordinated Indenture defines "SENIOR INDEBTEDNESS" as obligations issued under
the Senior Indenture between Morgan Stanley (as predecessor to the Issuer) and
The Chase Manhattan Bank (formerly known as Chemical Bank), as trustee, dated
April 15, 1989, as supplemented by a First Supplemental Senior Indenture dated
as of May 15, 1991 and a Second Supplemental Indenture, dated as of April 15,
1996 and a Third Supplemental Indenture dated as of June 1, 1997, between the
Issuer and The Chase Manhattan Bank, as trustee, or the Senior Subordinated
Indenture between Morgan Stanley (as predecessor to the Issuer) and The First
National Bank of Chicago, as trustee, dated as of April 15, 1989, as
supplemented by a First Supplemental Subordinated Indenture dated as of May 15,
1991 and a Second Supplemental Subordinated Indenture dated as of April 15, 1996
and by a Third Supplemental Subordinated Indenture dated as of June 1, 1997
between the Issuer and The First National Bank of Chicago, as trustee, and any
other obligations (other than non-recourse obligations, the debt securities,
including this Debenture, issued under the Junior Subordinated Indenture or any
other obligations specifically designated as being subordinate in right of
payment to Senior Indebtedness) of, or guaranteed or assumed by, the Issuer for
borrowed money or evidenced by

                                       9
<PAGE>
 
bonds, debentures or other similar instruments, and amendments, renewals,
extensions, modifications and refundings of any such indebtedness or obligation.

   This Debenture, and any Debenture or Debentures issued upon transfer or
exchange hereof, is issuable only in fully registered form, without coupons, and
is issuable only in denominations of U.S. $25 and any integral multiple of U.S.
$25 in excess thereof, unless otherwise indicated on the face thereof.

   The Bank of New York has been appointed registrar for the Debentures (the
"REGISTRAR," which term includes any successor registrar appointed by the
Issuer), and the Registrar will maintain at its office in The City of New York a
register for the registration and transfer of Debentures. This Debenture may be
transferred at the aforesaid office of the Registrar by surrendering this
Debenture for cancellation, accompanied by a written instrument of transfer in
form satisfactory to the Registrar and duly executed by the registered holder
hereof in person or by the holder's attorney duly authorized in writing, and
thereupon the Registrar shall issue in the name of the transferee or
transferees, in exchange herefor, a new Debenture or Debentures having identical
terms and provisions and having a like aggregate principal amount in authorized
denominations, subject to the terms and conditions set forth herein; provided,
however, that the Registrar will not be required (i) to register the transfer of
or exchange any Debenture that has been called for redemption in whole or in
part, except the unredeemed portion of Debentures being redeemed in part or (ii)
to register the transfer of or exchange Debentures to the extent and during the
period so provided in the Junior Subordinated Indenture with respect to the
redemption of Debentures. Debentures are exchangeable at said office for other
Debentures of other authorized denominations of equal aggregate principal amount
having identical terms and provisions. All such exchanges and transfers of
Debentures will be free of charge, but the Issuer may require payment of a sum
sufficient to cover any tax or other governmental charge in connection
therewith. All Debentures surrendered for exchange shall be accompanied by a
written instrument of transfer in form satisfactory to the Registrar and
executed by the registered holder in person or by the holder's attorney duly
authorized in writing. The date of registration of any Debenture delivered upon
any exchange or transfer of Debentures shall be such that no gain or loss of
interest results from such exchange or transfer.

   In case this Debenture shall at any time become mutilated, defaced or be
destroyed, lost or stolen and this Debenture or evidence of the loss, theft or
destruction thereof (together with the indemnity hereinafter referred to and
such other documents or proof as may be required in the premises) shall be
delivered to the Registrar, a new Debenture of like tenor will be issued by the
Issuer in exchange for this Debenture, but, if this Debenture has been
destroyed, lost or stolen, only upon receipt of evidence satisfactory to the
Registrar and the Issuer that such Debenture was destroyed or lost or stolen
and, if required, upon receipt also of indemnity satisfactory to each of them.
All expenses and reasonable charges associated with procuring such indemnity and
with the preparation, authentication and delivery of a new Debenture shall be
borne by the owner of the Debenture mutilated, defaced, destroyed, lost or
stolen.

   The Junior Subordinated Indenture permits the Issuer and the Trustee, with
the consent of the holders of not less than a majority in aggregate principal
amount of the debt securities of all

                                       10
<PAGE>
 
series issued under the Junior Subordinated Indenture then outstanding and
affected (voting as one class), to execute supplemental indentures adding any
provisions to or changing in any manner the rights of the holders of each series
so affected; provided that the Issuer and the Trustee may not, without the
consent of the holder of each outstanding debt security affected thereby and the
prior written consent of each registered holder of Capital Securities, to the
extent that the Debentures are held by a MSDW Capital Trust, (a) extend the
final maturity of any such debt security, or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon,
except as otherwise provided herein or in the Junior Subordinated Indenture, or
reduce any amount payable on redemption or repayment thereof, or change the
currency of payment thereof, or impair or affect the rights of any holder to
institute suit for the payment thereof without the consent of the holder of each
debt security so affected or (b) reduce the aforesaid percentage in principal
amount of debt securities the consent of the holders of which is required for
any such supplemental indenture; provided, however, that neither this Debenture
nor the Junior Subordinated Indenture may be amended to alter the subordination
provisions hereof or thereof without the written consent of each holder of
Senior Indebtedness then outstanding that would be adversely affected thereby.
In addition, so long as any of the Capital Securities remain outstanding, no
such modification may be made that adversely affects the holders of such Capital
Securities in any material respect, and no termination of the Junior
Subordinated Indenture may occur, and no waiver of any Event of Default or
compliance with any covenant under the Junior Subordinated Indenture may be
effective, without the prior consent of the holders of at least a majority of
the aggregate Liquidation Amount of the outstanding Capital Securities unless
and until the principal of (and premium, if any, on) the Debentures and all
accrued and unpaid interest thereon have been paid in full and certain other
conditions are satisfied. So long as the Issuer acts in accordance with the
terms of the Debentures, the Issuer may shorten the Stated Maturity of and defer
interest payable on the Debentures, in each case in accordance with the terms
hereof without the consent of the Issuer Trust or the holders of Capital
Securities.  However, the Issuer may not amend this Debenture or the Junior
Subordinated Indenture to remove the rights of registered holders of Capital
Securities to institute a Direct Action without the prior written consent of all
the registered holders of Capital Securities of the Trust.

   So long as this Debenture shall be outstanding, the Issuer will cause to be
maintained an office or agency for the payment of the principal of and premium,
if any, and interest on this Debenture as herein provided in the Borough of
Manhattan, The City of New York, and an office or agency in said Borough of
Manhattan for the registration, transfer and exchange as aforesaid of the
Debentures. The Issuer may designate other agencies for the payment of said
principal, premium and interest at such place or places (subject to applicable
laws and regulations) as the Issuer may decide. So long as there shall be such
an agency, the Issuer shall keep the Trustee advised of the names and locations
of such agencies, if any are so designated.

   With respect to moneys paid by the Issuer and held by the Trustee or any
Paying Agent for payment of the principal of or interest or premium, if any, on
any Debentures that remain unclaimed at the end of two years after such
principal, interest or premium shall have become due and payable (whether at
maturity or upon call for redemption or otherwise), (i) the Trustee or such
Paying Agent shall notify the holders of such Debentures that such moneys shall
be repaid to the Issuer and any person claiming such moneys shall thereafter
look only to the Issuer for payment thereof and (ii)

                                       11
<PAGE>
 
such moneys shall be so repaid to the Issuer. Upon such repayment all liability
of the Trustee or such Paying Agent with respect to such moneys shall thereupon
cease, without, however, limiting in any way any obligation that the Issuer may
have to pay the principal of or interest or premium, if any, on this Debenture
as the same shall become due.

   No provision of this Debenture or of the Junior Subordinated Indenture shall
alter or impair the obligation of the Issuer, which is absolute and
unconditional, to pay the principal of, premium, if any, and interest on this
Debenture at the time, place, and rate, and in the coin or currency, herein
prescribed unless otherwise agreed between the Issuer and the registered holder
of this Debenture.

   Prior to due presentment of this Debenture for registration of transfer, the
Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the
holder in whose name this Debenture is registered as the owner hereof for all
purposes, whether or not this Debenture be overdue, and none of the Issuer, the
Trustee or any such agent shall be affected by notice to the contrary.

   No recourse shall be had for the payment of the principal of, premium, if
any, or the interest on this Debenture, for any claim based hereon, or otherwise
in respect hereof, or based on or in respect of the Junior Subordinated
Indenture or any indenture supplemental thereto, against any incorporator,
shareholder, officer or director, as such, past, present or future, of the
Issuer or of any successor corporation, either directly or through the Issuer or
any successor corporation, whether by virtue of any constitution, statute or
rule of law or by the enforcement of any assessment or penalty or otherwise, all
such liability being, by the acceptance hereof and as part of the consideration
for the issue hereof, expressly waived and released.

     This Debenture shall for all purposes be governed by, and construed in
accordance with, the laws of the State of New York.

                           DISTRIBUTIONS; REDEMPTION

     SECTION 4.1.  Distributions.

     (a) The Trust Securities represent undivided beneficial interests in the
Trust Property, and Distributions (including of Additional Amounts) will be made
on the Trust Securities at the rate and on the dates that payments of interest
(including of Additional Interest, as defined in the Indenture) are made on the
Junior Subordinated Debentures.  Accordingly:

          (i) Distributions on the Trust Securities shall be cumulative and will
     accumulate whether or not there are funds of the Issuer Trust available for
     the payment of Distributions.  Distributions shall accumulate from and
     including March 12, 1998, and, except in the event (and to the extent) that
     the Depositor exercises its right to defer the payment of interest on the
     Junior Subordinated Debentures pursuant to the Indenture, shall be payable
     quarterly in arrears on February 28, May 30, August 30  and November 30 of
     each year, commencing on May 30, 1998.  If any date on which a Distribution
     is otherwise payable on the Trust Securities is not a Business Day, then
     the payment of such Distribution shall be made on the next succeeding day
     that is a Business Day (without any interest or other payment in respect of
     any such delay), with the same force and effect as if made on the date on
     which such payment was originally payable (each date on which distributions
     are payable in accordance with this Section 4.1(a), a "Distribution Date").

          (ii) The Trust Securities shall be entitled to Distributions payable
     at a rate of 7.10% per annum of the Liquidation Amount of the Trust
     Securities.  The amount of Distributions payable for any period less than a
     full Distribution period shall be computed on the basis of a 360-day year
     of twelve 30-day months and the actual number of days elapsed in a partial
     month in a period.  Distributions payable for each full Distribution period
     will be computed by dividing the rate per annum by four (4).  The amount of
     Distributions payable for any period shall include any Additional Amounts
     in respect of such period.

          (iii)  So long as no Debenture Event of Default has occurred and is
     continuing, the Depositor has the right under the Indenture to defer the
     payment of interest on the Junior Subordinated Debentures at any time and
     from time to time for a period not exceeding 20 consecutive quarterly
     periods (an "Extension Period"), provided that no Extension Period may
     extend beyond the stated maturity of the Junior Subordinated Debentures (as
     such stated maturity may be shortened in accordance with the terms of the
     Indenture).  As a consequence of any such deferral, quarterly Distributions
     on the Trust Securities by the Issuer Trust will also be deferred to the
     extent and except as provided in the Junior Substantial Debentures, and the
     amount of Distributions to which Holders of the Trust Securities are
     entitled that have been so deferred will accumulate additional
     Distributions thereon at the rate per annum of 7.10%, compounded quarterly
     from the most recent Distribution payment date on which Distributions were
     paid, computed on the basis of a 360-day year of twelve 30-day months and
     the actual days elapsed in a partial month in such period.  Additional
     Distributions payable for each full Distribution period will be computed by
     dividing the rate per annum by four (4).  The term "Distributions" as used
     in Section 4.1 shall include any such additional Distributions provided
     pursuant to this Section 4.1(a)(iii).

                                       14
<PAGE>
 
          (iv) Distributions on the Trust Securities shall be made by the
     Property Trustee from the Payment Account and shall be payable on each
     Distribution Date only to the extent that the Issuer Trust has funds then
     on hand and available in the Payment Account for the payment of such
     Distributions.

     (b) Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities at the close of business on the relevant
record date, which shall be at the close of business on the 15th calendar day of
the month next preceding the relevant Distribution Date, whether or not a
Business Day.

     SECTION 4.2.  Redemption.

     (a) On each Debenture Redemption Date and on the stated maturity of the
Junior Subordinated Debentures, the Issuer Trust will be required to redeem a
Like Amount of Trust Securities at the Redemption Price.

     (b) Notice of redemption shall be given by the Property Trustee by first-
class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior
to the Redemption Date to each Holder of Trust Securities to be redeemed, at
such Holder's address appearing in the Security Register.  All notices of
redemption shall state:

          (i)  the Redemption Date;

          (ii) the Redemption Price, or if the Redemption Price cannot be
     calculated prior to the time the notice is required to be sent, the
     estimate of the Redemption Price provided pursuant to the Indenture
     together with a statement that it is an estimate and that the actual
     Redemption Price will be calculated on the third Business Day prior to the
     Redemption Date (and if an estimate is provided, a further notice shall be
     sent of the actual Redemption Price on the date, or as soon as practicable
     thereafter, that notice of such actual Redemption Price is received
     pursuant to the Indenture);

          (iii)  the CUSIP number or CUSIP numbers of the Capital Securities
     affected;

          (iv) if less than all the Outstanding Trust Securities are to be
     redeemed, the identification and the total Liquidation Amount of the
     particular Trust Securities to be redeemed;

          (v) that, on the Redemption Date, the Redemption Price will become due
     and payable upon each such Trust Security to be redeemed and that
     Distributions thereon will cease to accumulate on and after said date,
     except as provided in Section 4.2(d) below; and

          (vi) the place or places where Trust Securities are to be surrendered
     for the payment of the Redemption Price.

     The Issuer Trust in issuing the Trust Securities shall use "CUSIP"numbers,
and the Property Trustee shall indicate the "CUSIP" numbers of the Trust
Securities in notices of redemption and related materials as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Trust Securities
or as contained in any notice of redemption and related material.

     (c) The Trust Securities redeemed on each Redemption Date shall be redeemed
at the Redemption Price with the applicable proceeds from the contemporaneous
redemption of Junior Subordinated Debentures.  Redemptions of the Trust
Securities shall be made and the Redemption Price shall be payable on each
Redemption Date only to the extent that the Issuer Trust has funds then on hand
and legally available in the Payment Account for the payment of such Redemption
Price.

                                       15
<PAGE>
 
     (d) If the Issuer Trust gives a notice of redemption in respect of any
Capital Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 4.2(c), the Property Trustee will, with respect to
Capital Securities held in book-entry form, irrevocably deposit with the
Clearing Agency for such Capital Securities, to the extent available therefor,
funds sufficient to pay the applicable Redemption Price and will give such
Clearing Agency irrevocable instructions and authority to pay the Redemption
Price to the Holders of the Capital Securities.  With respect to Capital
Securities that are not held in book-entry form, the Property Trustee, subject
to Section 4.2(c), will irrevocably deposit with the Paying Agent, to the extent
available therefor, funds sufficient to pay the applicable Redemption Price and
will give the Paying Agent irrevocable instructions and authority to pay the
Redemption Price to the Holder of the Capital Securities upon surrender of their
Capital Securities Certificates.  Notwithstanding the foregoing, Distributions
payable on or prior to the Redemption Date for any Trust Securities called for
redemption shall be payable to the Holders of such Trust Securities as they
appear on the Securities Register for the Trust Securities on the relevant
record dates for the related Distribution Dates.  If notice of redemption shall
have been given and funds deposited as required, then, upon the date of such
deposit, all rights of Holders holding Trust Securities so called for redemption
will cease, except the right of such Holders to receive the Redemption Price and
any Distribution payable in respect of the Trust Securities on or prior to the
Redemption Date, but without interest, and such Securities will cease to be
Outstanding.  In the event that any date on which any applicable Redemption
Price is payable is not a Business Day, then payment of the applicable
Redemption Price payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay) with the same force and effect as if made on such date.  In the
event that payment of the Redemption Price in respect of any Trust Securities
called for redemption is improperly withheld or refused and not paid either by
the Issuer Trust or by the Depositor pursuant to the Guarantee Agreement,
Distributions on such Trust Securities will continue to accumulate, as set forth
in Section 4.1, from the Redemption Date originally established by the Issuer
Trust for such Trust Securities to the date such applicable Redemption Price is
actually paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the applicable Redemption Price.

     (e) Subject to Section 4.3(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of such Trust Securities to be redeemed shall be allocated
pro rata to the Common Securities and the Capital Securities based on the
relative Liquidation Amounts of such classes.  The particular Capital Securities
to be redeemed shall be selected on a pro rata basis based on their respective
Liquidation Amounts not more than 60 days prior to the Redemption Date by the
Property Trustee from the Outstanding Capital Securities not previously called
for redemption, or if the Capital Securities are then held in the form of a
Global Capital Security in accordance with the customary procedures for the
Clearing Agency.  The Property Trustee shall promptly notify the Securities
Registrar in writing of the Capital Securities selected for redemption and, in
the case of any Capital Securities selected for partial redemption, the
Liquidation Amount thereof to be redeemed.  For all purposes of this Trust
Agreement, unless the context otherwise requires, all provisions relating to the
redemption of Capital Securities shall relate, in the case of any Capital
Securities redeemed or to be redeemed only in part, to the portion of the
aggregate Liquidation Amount of Capital Securities that has been or is to be
redeemed.

     SECTION 4.3.  Subordination of Common Securities.

     (a) Payment of Distributions (including Additional Amounts, if applicable)
on, the Redemption Price of, and the Liquidation Distribution in respect of, the
Trust Securities, as applicable, shall be made, subject to Section 4.2(e), pro
rata among the Common Securities and the Capital Securities based on the
Liquidation Amount of such Trust Securities; provided, however, that if on any
Distribution Date or Redemption Date any Event of Default resulting from a
Debenture Event of Default in Section 5.1(a) or 5.1(b) of the Indenture shall
have occurred and be continuing, no payment of any Distribution (including any
Additional Amounts) on, Redemption Price of, or Liquidation Distribution in
respect of, any Common Security, and no other payment on account of the
redemption, liquidation or other acquisition of Common Securities, shall

                                       16
<PAGE>
 
be made unless payment in full in cash of all accumulated and unpaid
Distributions (including any Additional Amounts) on all Outstanding Capital
Securities for all Distribution periods terminating on or prior thereto, or, in
the case of payment of the Redemption Price, the full amount of such Redemption
Price on all Outstanding Capital Securities then called for redemption, or in
the case of payment of the Liquidation Distribution the full amount of such
Liquidation Distribution on all Outstanding Capital Securities, shall have been
made or provided for, and all funds immediately available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions (including any Additional Amounts) on, the Redemption Price of, or
the Liquidation Distribution in respect of Capital Securities then due and
payable.  The existence of an Event of Default does not entitle the Holders of
Trust Securities to accelerate the maturity thereof.

     (b) In the case of the occurrence of any Event of Default resulting from
any Debenture Event of Default, the Holder of the Common Securities shall have
no right to act with respect to any such Event of Default under this Trust
Agreement until the effects of all such Events of Default with respect to the
Capital Securities have been cured, waived or otherwise eliminated.  Until all
such Events of Default under this Trust Agreement with respect to the Capital
Securities have been so cured, waived or otherwise eliminated, the Property
Trustee shall act solely on behalf of the Holders of the Capital Securities and
not on behalf of the Holder of the Common Securities, and only the Holders of
the Capital Securities will have the right to direct the Property Trustee to act
on their behalf.

     SECTION 4.4.  Payment Procedures.

     Payments of Distributions (including any Additional Amounts) in respect of
the Capital Securities shall be made by check mailed to the address of the
Person entitled thereto as such address shall appear on the Securities Register
or, if the Capital Securities are held by a Clearing Agency, such Distributions
shall be made to the Clearing Agency in immediately available funds, which will
credit the relevant accounts on the applicable Distribution Dates.  Payments of
Distributions to Holders of $1,000,000 or more in aggregate Liquidation Amount
of Capital Securities may be made by wire transfer of immediately available
funds upon written request of such Holder to the Securities Registrar not later
than 15 calendar days prior to the date on which the Distribution is payable.
Payments in respect of the Common Securities shall be made in such manner as
shall be mutually agreed between the Property Trustee and the Holder of the
Common Securities.

     SECTION 4.5.  Tax Returns and Reports.

     The Administrators shall prepare (or cause to be prepared), at the
Depositor's expense, and file all United States Federal, state and local tax and
information returns and reports required to be filed by or in respect of the
Issuer Trust.  In this regard, the Administrators shall (a) prepare and file (or
cause to be prepared and filed) all Internal Revenue Service forms required to
be filed in respect of the Issuer Trust in each taxable year of the Issuer Trust
and (b) prepare and furnish (or cause to be prepared and furnished) to each
Holder all Internal Revenue Service forms required to be provided by the Issuer
Trust.  The Administrators shall provide the Depositor and the Property Trustee
with a copy of all such returns and reports promptly after such filing or
furnishing.  The Issuer Trustees shall comply with United States Federal
withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Holders under the Trust Securities.

     On or before December 15 of each year during which any Capital Securities
are Outstanding, the Administrators shall furnish to the Property Trustee such
information as may be reasonably requested by the Property Trustee in order that
the Property Trustee may prepare the information which it is required to report
for such year on Internal Revenue Service Forms 1096 and 1099 pursuant to
Section 6049 of the Code.  Such information shall include the amount of original
issue discount includible in income for each Outstanding Capital Security during
such year.

<PAGE>
 
     SECTION 4.6.  Payment of Taxes, Duties, Etc. of the Issuer Trust.

     Upon receipt under the Junior Subordinated Debentures of Additional Sums,
the Property Trustee shall promptly pay, or cause the Administrators to pay in
connection with the filing of any tax returns or reports pursuant to Section
4.5, any taxes, duties or governmental charges of whatsoever nature (other than
withholding taxes) imposed on the Issuer Trust by the United States or any other
taxing authority.

     SECTION 4.7.  Payments under Indenture or Pursuant to Direct Actions.

     Any amount payable hereunder to any Holder of Capital Securities shall be
reduced by the amount of any corresponding payment such Holder has directly
received pursuant to Section 5.8 of the Indenture or Section 5.13 of this Trust
Agreement.

     SECTION 4.8.  Liability of the Holder of Common Securities.

     The Holder of Common Securities shall be liable for the debts and
obligations of the Issuer Trust as set forth in Section 6.7 of the Indenture
regarding allocation of expenses.


                                   ARTICLE V

                         TRUST SECURITIES CERTIFICATES

     SECTION 5.1.  Initial Ownership.

     Upon the creation of the Issuer Trust and the contribution by the Depositor
pursuant to Section 2.3 and until the issuance of the Trust Securities, and at
any time during which no Trust Securities are Outstanding, the Depositor shall
be the sole beneficial owner of the Issuer Trust.

     SECTION 5.2.  The Trust Securities Certificates.

     (a) The Trust Securities Certificates shall be issued in multiples of $25
and shall be executed on behalf of the Issuer Trust by manual or facsimile
signature of at least one Administrator.  Trust Securities Certificates bearing
the manual signatures of individuals who were, at the time when such signatures
shall have been affixed, authorized to sign on behalf of the Issuer Trust, shall
be validly issued and entitled to the benefits of this Trust Agreement,
notwithstanding that such individuals or any of them shall have ceased to be so
authorized prior to the delivery of such Trust Securities Certificates or did
not hold such offices at the date of delivery of such Trust Securities
Certificates.  A transferee of a Trust Securities Certificate shall become a
Holder, and shall be entitled to the rights and subject to the obligations of a
Holder hereunder, upon due registration of such Trust Securities Certificate in
such transferee's name pursuant to Section 5.5.

     (b) Upon their original issuance, Capital Securities Certificates shall be
issued in the form of one or more fully registered Global Capital Securities
Certificates which will be deposited with or on behalf of the Depositary and
registered in the name of the Depositary's nominee.  Unless and until it is
exchangeable in whole or in part for the Capital Securities in definitive form,
a global 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 of such Depositary or a nominee of such successor.

     (c) A single Common Securities Certificate representing the Common
Securities shall be issued to the Depositor in the form of a definitive Common
Securities Certificate.

                                       18
<PAGE>
 
     SECTION 5.3.  Execution and Delivery of Trust Securities Certificates.

     At the Closing Date, and on the date, if any, on which the Underwriters
exercise their option to purchase additional Capital Securities pursuant to the
terms of the Underwriting Agreement, as applicable, at least one of the
Administrators shall cause Trust Securities Certificates, in an aggregate
Liquidation Amount as provided in Sections 2.4 and 2.5, to be executed on behalf
of the Issuer Trust by manual or facsimile signature. The Capital Securities so
executed shall be delivered to the Property Trustee and upon such delivery the
Property Trustee shall manually authenticate upon the written order of the
Depositor such Capital Securities Certificates and deliver such Capital
Securities Certificates upon the written order of the Depositor, executed by an
authorized officer thereof, without further corporate action by the Depositor,
in authorized denominations.

     SECTION 5.4.  Global Capital Security.

     (a) Any Global Capital Security issued under this Trust Agreement shall be
registered in the name of the nominee of the Clearing Agency and delivered to
such custodian therefor, and such Global Capital Security shall constitute a
single Capital Security for all purposes of this Trust Agreement.

     (b) Notwithstanding any other provision in this Trust Agreement, a Global
Capital Security may not be exchanged in whole or in part for Capital Securities
registered, and no transfer of the Global Capital Security in whole or in part
may be registered, in the name of any Person other than the Clearing Agency for
such Global Capital Security, or its nominee thereof unless (i) such Clearing
Agency advises the Property Trustee in writing that such Clearing Agency is no
longer willing or able to properly discharge its responsibilities as Clearing
Agency with respect to such Global Capital Security or if it ceases to be a
Clearing Agency under the Exchange Act, and the Depositor is unable to locate a
qualified successor within 90 days after receiving such notice or becoming aware
that the Depositary is no longer so registered, (ii) the Issuer Trust at its
option advises the Depositary in writing that it elects to terminate the book-
entry system through the Clearing Agency, or (iii) there shall have occurred and
be continuing an Event of Default.

     (c) If a Capital Security is to be exchanged in whole or in part for a
beneficial interest in a Global Capital Security, then either (i) such Global
Capital Security shall be so surrendered for exchange or cancellation as
provided in this Article V or (ii) the aggregate Liquidation Amount thereof
shall be reduced or increased by an amount equal to the portion thereof to be so
exchanged or cancelled or equal to the Liquidation Amount of such other Capital
Security to be so exchanged for a beneficial interest therein, as the case may
be, by means of an appropriate adjustment made on the records of the Security
Registrar, whereupon the Property Trustee, in accordance with the Applicable
Procedures, shall instruct the Clearing Agency or its authorized representative
to make a corresponding adjustment to its records.  Upon any such surrender or
adjustment of a Global Capital Security by the Clearing Agency, accompanied by
registration instructions, the Property Trustee shall, subject to Section 5.4(b)
and as otherwise provided in this Article V, authenticate and deliver any
Capital Securities issuable in exchange for such Global Capital Security (or any
portion thereof) in accordance with the instructions of the Clearing Agency.
The Property Trustee shall not be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be fully protected in
relying on, such instructions.

     (d) Every Capital Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Capital Security or any
portion thereof, whether pursuant to this Article V or Article IV or otherwise,
shall be authenticated and delivered in the form of, and shall be, a Global
Capital Security, unless such Global Capital Security is registered in the name
of a Person other than the Clearing Agency for such Global Capital Security or a
nominee thereof.

     (e) The Clearing Agency or its nominee, as the registered owner of a Global
Capital Security, shall be considered the Holder of the Capital Securities
represented by such Global Capital Security for all purposes under this Trust
Agreement and the Capital Securities, and owners of beneficial interests in such
Global Capital Security shall hold such interests pursuant to the Applicable
Procedures and, except as otherwise

                                       19
<PAGE>
 
provided herein, shall not be entitled to receive physical delivery of any such
Capital Securities in definitive form and shall not be considered the Holders
thereof under this Trust Agreement.  Accordingly, any such owner's beneficial
interest in the Global Capital Security shall be shown only on, and the transfer
of such interest shall be effected only through, records maintained by the
Clearing Agency or its nominee.  Neither the Property Trustee nor the Securities
Registrar shall have any liability in respect of any transfers effected by the
Clearing Agency.

     (f) The rights of owners of beneficial interests in a Global Capital
Security shall be exercised only through the Clearing Agency and shall be
limited to those established by law and agreements between such owners and the
Clearing Agency.

     SECTION 5.5.  Registration of Transfer and Exchange Generally; Certain
Transfers and Exchanges; Capital Securities Certificates.

     (a) The Property Trustee shall keep or cause to be kept at its Corporate
Trust Office a register or registers for the purpose of registering Capital
Securities Certificates and transfers and exchanges of Capital Securities
Certificates in which the registrar and transfer agent with respect to the
Capital Securities (the "Securities Registrar"), subject to such reasonable
regulations as it may prescribe, shall provide for the registration of Capital
Securities Certificates and Common Securities Certificates (subject to Section
5.11 in the case of Common Securities Certificates) and registration of
transfers and exchanges of Capital Securities Certificates as herein provided.
Such register is herein sometimes referred to as the "Securities Register." The
Property Trustee is hereby appointed "Securities Registrar" for the purpose of
registering Capital Securities and transfers of Capital Securities as herein
provided.

     Upon surrender for registration of transfer of any Capital Security at the
offices or agencies of the Property Trustee designated for that purpose an
Administrator shall execute, and the Property Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Capital Securities of the same series of any authorized denominations of
like tenor and aggregate Liquidation Amount and bearing such legends as may be
required by this Trust Agreement.

     At the option of the Holder, Capital Securities may be exchanged for other
Capital Securities of any authorized denominations, of like tenor and aggregate
Liquidation Amount and bearing such legends as may be required by this Trust
Agreement, upon surrender of the Capital Securities to be exchanged as such
office or agency.  Whenever any securities are so surrendered for exchange, an
Administrator shall execute and the Property Trustee shall authenticate and
deliver the Capital Securities that the Holder making the exchange is entitled
to receive.

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

     Every Capital Security presented or surrendered for transfer or exchange
shall (if so required by the Property Trustee) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Property Trustee and the Securities Registrar, duly executed by the Holder
thereof or such Holder's attorney duly authorized in writing.

     No service charge shall be made to a Holder for any transfer or exchange of
Capital Securities, but the Property Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any transfer or exchange of Capital Securities.

     Neither the Issuer Trust nor the Property Trustee shall be required,
pursuant to the provisions of this Section, (i) to issue, register the transfer
of or exchange any Capital Security during a period beginning at the

                                       20
<PAGE>
 
opening of business 15 days before the first mailing of the notice of
redemption, or (ii) to register the transfer of or exchange any Capital Security
so selected for redemption in whole or in part, except, in the case of any such
Capital Security to be redeemed in part, any portion thereof not to be redeemed.

     (b) Certain Transfers and Exchanges.  Trust Securities may only be
transferred, in whole or in part, in accordance with the terms and conditions
set forth in this Trust Agreement.  To the fullest extent permitted by law, any
transfer or purported transfer of any Trust Security not made in accordance with
this Trust Agreement shall be null and void.

          (i)    Non Global Security to Non Global Security.  A Capital Security
     that is not a Global Capital Security may be transferred, in whole or in
     part, to a Person who takes delivery in the form of another Trust Security
     that is not a Global Security as provided in Section 5.5(a).

          (ii)   Free Transferability.  Subject to this Section 5.5, Capital
     Securities shall be freely transferable.

          (iii)  Exchanges Between Global Capital Security and Non-Global
     Capital Security.  A beneficial interest in a Global Capital Security may
     be exchanged for a Capital Security that is not a Global Capital Security
     as provided in Section 5.4.

     SECTION 5.6.  Mutilated, Destroyed, Lost or Stolen Trust Securities
Certificates.

     If (a) any mutilated Trust Securities Certificate shall be surrendered to
the Securities Registrar, or if the Securities Registrar shall receive evidence
to its satisfaction of the destruction, loss or theft of any Trust Securities
Certificate and (b) there shall be delivered to the Securities Registrar and the
Administrators such security or indemnity as may be required by them to save
each of them harmless, then in the absence of notice that such Trust Securities
Certificate shall have been acquired by a bona fide purchaser, the
Administrators, or any one of them, on behalf of the Issuer Trust shall execute
and make available for delivery, and the Property Trustee shall authenticate, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen Trust
Securities Certificate, a new Trust Securities Certificate of like class, tenor
and denomination.  In connection with the issuance of any new Trust Securities
Certificate under this Section, the Administrators or the Securities Registrar
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith.  Any duplicate
Trust Securities Certificate issued pursuant to this Section shall constitute
conclusive evidence of an undivided beneficial interest in the assets of the
Issuer Trust corresponding to that evidenced by the lost, stolen or destroyed
Trust Certificate, as if originally issued, whether or not the lost, stolen or
destroyed Trust Securities Certificate shall be found at any time.

     SECTION 5.7.  Persons Deemed Holders.

     The Issuer Trustees or the Securities Registrar shall treat the Person in
whose name any Trust Securities are issued as the owner of such Trust Securities
for the purpose of receiving Distributions and for all other purposes
whatsoever, and none of the Issuer Trustees, the Administrators nor the
Securities Registrar shall be bound by any notice to the contrary.

     SECTION 5.8.  Access to List of Holders' Names and Addresses.

     Each Holder and each Owner shall be deemed to have agreed not to hold the
Depositor, the Property Trustee, or the Administrators accountable by reason of
the disclosure of its name and address, regardless of the source from which such
information was derived.

                                       21
<PAGE>
 
     SECTION 5.9.  Maintenance of Office or Agency.

     The Property Trustee shall designate, with the consent of the
Administrators, which consent shall not be unreasonably withheld, an office or
offices or agency or agencies where Capital Securities Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Issuer Trustees in respect of the Trust Securities
Certificates may be served.  The Property Trustee initially designates its
Corporate Trust Office at 101 Barclay Street, Floor 21 West, New York, NY
10286, Attention:  Corporate Trust Administration, as its corporate trust office
for such purposes.  The Property Trustee shall give prompt written notice to the
Depositor, the Administrators and to the Holders of any change in the location
of the Securities Register or any such office or agency.

     SECTION 5.10.  Appointment of Paying Agent.

     The Paying Agent shall make Distributions to Holders from the Payment
Account and shall report the amounts of such Distributions to the Property
Trustee and the Administrators.  Any Paying Agent shall have the revocable power
to withdraw funds from the Payment Account solely for the purpose of making the
Distributions referred to above.  The Property Trustee may revoke such power and
remove any Paying Agent in its sole discretion.  The Paying Agent shall
initially be the Property Trustee.  Any Person acting as Paying Agent shall be
permitted to resign as Paying Agent upon 30 days' written notice to the
Administrators and the Property Trustee.  In the event that the Property Trustee
shall no longer be the Paying Agent or a successor Paying Agent shall resign or
its authority to act be revoked, the Property Trustee shall appoint a successor
(which shall be a bank or trust company) that is reasonably acceptable to the
Administrators to act as Paying Agent.  Such successor Paying Agent or any
additional Paying Agent appointed by the Property Trustee shall execute and
deliver to the Issuer Trustees an instrument in which such successor Paying
Agent or additional Paying Agent shall agree with the Issuer Trustees that as
Paying Agent, such successor Paying Agent or additional Paying Agent will hold
all sums, if any, held by it for payment to the Holders in trust for the benefit
of the Holders entitled thereto until such sums shall be paid to such Holders.
The Paying Agent shall return all unclaimed funds to the Property Trustee and
upon removal of a Paying Agent such Paying Agent shall also return all funds in
its possession to the Property Trustee.  The provisions of Sections 8.1, 8.3 and
8.6 herein shall apply to the Bank also in its role as Paying Agent, for so long
as the Bank shall act as Paying Agent and, to the extent applicable, to any
other paying agent appointed hereunder.  Any reference in this Trust Agreement
to the Paying Agent shall include any co-paying agent chosen by the Property
Trustee unless the context requires otherwise.

     SECTION 5.11.  Ownership of Common Securities by Depositor.

     At the Closing Date, the Depositor shall acquire and retain beneficial and
record ownership of the Common Securities.  Neither the Depositor nor any
successor Holder of the Common Securities may transfer less than all the Common
Securities, and the Depositor or any such successor Holder may transfer the
Common Securities only (i) in connection with a consolidation or merger of the
Depositor into another Person or any conveyance, transfer or lease by the
Depositor of its properties and assets substantially as an entirety to any
Person, pursuant to Section 8.1 of the Indenture, or (ii) to an Affiliate of the
Depositor in compliance with applicable law (including the Securities Act and
applicable state securities and blue sky laws).  To the fullest extent permitted
by law, any attempted transfer of the Common Securities, other than as set forth
in the immediately preceding sentence, shall be void.  The Administrators shall
cause each Common Securities Certificate issued to the Depositor to contain a
legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT TO THE DEPOSITOR OR
AN AFFILIATE OF THE DEPOSITOR IN COMPLIANCE WITH APPLICABLE LAW AND SECTION 5.11
OF THE TRUST AGREEMENT."

<PAGE>
 
     SECTION 5.12.  Notices to Clearing Agency.

     To the extent that a notice or other communication to the Holders is
required under this Trust Agreement, for so long as Capital Securities are
represented by a Global Capital Securities Certificate, the Administrators and
the Issuer Trustees shall give all such notices and communications specified
herein to be given to the Clearing Agency, and shall have no obligations to the
Owners.

     SECTION 5.13.  Rights of Holders.

     (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Holders shall not have any right or title therein other than the undivided
beneficial ownership interest in the assets of the Issuer Trust conferred by
their Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Issuer Trust except as described
below.  The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement.  The Trust
Securities shall have no preemptive or similar rights and when issued and
delivered to Holders against payment of the purchase price therefor, as provided
herein, will be fully paid and nonassessable by the Issuer Trust.  Except as
otherwise provided in Section 4.8, the Holders of the Trust Securities, in their
capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

     (b) For so long as any Capital Securities remain Outstanding, if, upon a
Debenture Event of Default, the Debt Securities Trustee fails or the holders of
not less than 25% in principal amount of the outstanding Junior Subordinated
Debentures fail to declare the principal of all of the Junior Subordinated
Debentures to be immediately due and payable, the Holders of at least 25% in
Liquidation Amount of the Capital Securities then Outstanding shall have such
right to make such declaration by a notice in writing to the Property Trustee,
the Depositor and the Debt Securities Trustee.

     At any time after such a declaration of acceleration with respect to the
Junior Subordinated Debentures has been made and before a judgment or decree for
payment of the money due has been obtained by the Debt Securities Trustee as
provided in the Indenture, the Holders of a Majority in Liquidation Amount of
the Capital Securities, by written notice to the Property Trustee, the Depositor
and the Debt Securities Trustee, may rescind and annul such declaration and its
consequences if:

          (i) the Depositor has paid or deposited with the Debt Securities
     Trustee a sum sufficient to pay

               (A) all overdue installments of interest on all of the Junior
          Subordinated Debentures,

               (B) any accrued Additional Interest on all of the Junior
          Subordinated Debentures,

               (C) the principal of (and premium, if any, on) any Junior
          Subordinated Debentures which have become due otherwise than by such
          declaration of acceleration and interest and Additional Interest
          thereon at the rate borne by the Junior Subordinated Debentures, and

               (D) all sums paid or advanced by the Debt Securities Trustee
          under the Indenture and the reasonable compensation, expenses,
          disbursements and advances of the Debt Securities Trustee and the
          Property Trustee, their agents and counsel; and

                                       23
<PAGE>
 
          (ii) all Events of Default with respect to the Junior Subordinated
     Debentures, other than the non-payment of the principal of the Junior
     Subordinated Debentures which has become due solely by such acceleration,
     have been cured or waived as provided in Section 5.13 of the Indenture.

     If the Property Trustee fails to annul any such declaration and waive such
default, the Holders of at least a Majority in Liquidation Amount of the Capital
Securities shall also have the right to rescind and annul such declaration and
its consequences by written notice to the Depositor, the Property Trustee and
the Debt Securities Trustee, subject to the satisfaction of the conditions set
forth in Clause (i) and (ii) of this Section 5.13(b).

     The Holders of at least a Majority in Liquidation Amount of the Capital
Securities may, on behalf of the Holders of all the Capital Securities, waive
any past default under the Indenture, except a default in the payment of
principal or interest (unless such default has been cured and a sum sufficient
to pay all matured installments of interest and principal due otherwise than by
acceleration has been deposited with the Debt Securities Trustee) or a default
in respect of a covenant or provision which under the Indenture cannot be
modified or amended without the consent of the holder of each outstanding Junior
Subordinated Debentures.  No such rescission shall affect any subsequent default
or impair any right consequent thereon.

     Upon receipt by the Property Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, by Holders of the Capital
Securities all or part of which is represented by Global Capital Securities, a
record date shall be established for determining Holders of Outstanding Capital
Securities entitled to join in such notice, which record date shall be at the
close of business on the day the Property Trustee receives such notice.  The
Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such notice, whether or not such Holders
remain Holders after such record date; provided, that, unless such declaration
of acceleration, or rescission and annulment, as the case may be, shall have
become effective by virtue of the requisite percentage having joined in such
notice prior to the day which is 90 days after such record date, such notice of
declaration of acceleration, or rescission and annulment, as the case may be,
shall automatically and without further action by any Holder be canceled and of
no further effect.  Nothing in this paragraph shall prevent a Holder, or a proxy
of a Holder, from giving, after expiration of such 90-day period, a new written
notice of declaration of acceleration, or rescission and annulment thereof, as
the case may be, that is identical to a written notice which has been canceled
pursuant to the proviso to the preceding sentence, in which event a new record
date shall be established pursuant to the provisions of this Section 5.13(b).

     (c) For so long as any Capital Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, upon a Debenture Event of Default specified in Section
5.01(a) or 5.01(b) of the Indenture, any Holder of Capital Securities shall have
the right to institute a proceeding directly against the Depositor, pursuant to
Section 5.01 of the Indenture, for enforcement of payment to such Holder of the
principal amount of or interest on Junior Subordinated Debentures having an
aggregate principal amount equal to the aggregate Liquidation Amount of the
Capital Securities of such Holder (a "Direct Action").  Except as set forth in
Sections 5.13(b) and 5.13(c), the Holders of Capital Securities shall have no
right to exercise directly any right or remedy available to the holders of, or
in respect of, the Junior Subordinated Debentures.

                                  ARTICLE VI

                       ACTS OF HOLDERS; MEETINGS; VOTING

          SECTION 6.1.  Limitations on Holder's Voting Rights.

          (a) Except as provided in this Trust Agreement and in the Indenture
and as otherwise required by law, no Holder of Capital Securities shall have any
right to vote or in any manner otherwise control the administration, operation
and management of the Issuer Trust or the obligations of the parties hereto, nor
shall anything herein set forth or contained in the terms of the Trust
Securities Certificates be construed so as to constitute the Holders from time
to time as members of an association.

          (b) So long as any Junior Subordinated Debentures are held by the
Property Trustee on behalf of the Issuer Trust, the Property Trustee shall not
(i) direct the time, method and place of conducting any proceeding for any
remedy available to the Debt Securities Trustee, or executing any trust or power
conferred on the Property Trustee with respect to such Junior Subordinated
Debentures, (ii) waive any past default that may be waived under Section 5.10 of
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Junior Subordinated Debentures shall be due and payable
or (iv) consent to any amendment, modification or termination of the Indenture
or the Junior Subordinated Debentures, where such consent shall be required,
without, in each case, obtaining the prior approval of the Holders of at least a
Majority in Liquidation Amount of the Capital Securities, provided, however,
that where a consent under the Indenture would require the consent of each
Holder of Junior Subordinated Debentures affected thereby, no such consent shall
be given by the Property Trustee without the prior written consent of each
Holder of Capital Securities.  The Property Trustee shall not revoke any action
previously authorized or approved by a vote of the Holders of Capital
Securities, except by a subsequent vote of the Holders of Capital Securities.
The Property Trustee shall notify all Holders of the Capital Securities of any
notice of default received with respect to the Junior Subordinated Debentures.
In addition to obtaining the foregoing approvals of the Holders of the Capital
Securities, prior to taking any of the foregoing actions, the Property Trustee
shall, at the expense of the Depositor, obtain an Opinion of Counsel experienced
in such matters to the effect that such action will not cause the Issuer Trust
to be taxable as a corporation for United States Federal income tax purposes.

          (c) If any proposed amendment to the Trust Agreement provides for, or
the Issuer Trust otherwise proposes to effect, (i) any action that would
adversely affect in any material respect the interests, powers, preferences or
special rights of the Capital Securities, whether by way of amendment to the
Trust Agreement or otherwise, or (ii) the dissolution, winding-up or termination
of the Issuer Trust, other than pursuant to the terms of this Trust Agreement,
then the Holders of Outstanding Capital Securities as a class will be entitled
to vote on such amendment or proposal and such amendment or proposal shall not
be effective except with the approval of the Holders of at least a Majority in
Liquidation Amount of the Capital Securities.

          SECTION 6.2.  Notice of Meetings.

          Notice of all meetings of the Holders, stating the time, place and
purpose of the meeting, shall be given by the Property Trustee pursuant to
Section 10.8 to each Holder of record, at his registered address, at least 15
days and not more than 90 days before the meeting.  At any such meeting, any
business properly before the meeting may be so considered whether or not stated
in the notice of the meeting.  Any adjourned meeting may be held as adjourned
without further notice.

                                 SECTION 6.3.  Meetings of Holders.

          No annual meeting of Holders is required to be held.  The Property
Trustee, however, shall call a meeting of Holders to vote on any matter upon the
written request of the Holders of record of 25% of the aggregate Liquidation
Amount of the Capital Securities and the Administrators or the Property Trustee
may, at

                                       25
<PAGE>
 
any time in their discretion, call a meeting of Holders of Capital Securities to
vote on any matters as to which Holders are entitled to vote.

          Holders of at least a Majority in Liquidation Amount of the Capital
Securities, present in person or represented by proxy, shall constitute a quorum
at any meeting of Holders of the Capital Securities.

          If a quorum is present at a meeting, an affirmative vote by the
Holders of record present, in person or by proxy, holding Capital Securities
representing at least a Majority in Liquidation Amount of the Capital Securities
held by the Holders present, either in person or by proxy, at such meeting shall
constitute the action of the Holders of Capital Securities, unless this Trust
Agreement requires a greater number of affirmative votes.

          SECTION 6.4.  Voting Rights.

          Holders shall be entitled to one vote for each $25 of Liquidation
Amount represented by their Outstanding Trust Securities in respect of any
matter as to which such Holders are entitled to vote.

          SECTION 6.5.  Proxies, etc.

          At any meeting of Holders, any Holder entitled to vote thereat may
vote by proxy, provided that no proxy shall be voted at any meeting unless it
shall have been placed on file with the Property Trustee, or with such other
officer or agent of the Issuer Trust as the Property Trustee may direct, for
verification prior to the time at which such vote shall be taken.  Pursuant to a
resolution of the Property Trustee, proxies may be solicited in the name of the
Property Trustee or one or more officers of the Property Trustee.  Only Holders
of record shall be entitled to vote.  When Trust Securities are held jointly by
several Persons, any one of them may vote at any meeting in person or by proxy
in respect of such Trust Securities, but if more than one of them shall be
present at such meeting in person or by proxy, and such joint owners or their
proxies so present disagree as to any vote to be cast, such vote shall not be
received in respect of such Trust Securities.  A proxy purporting to be executed
by or on behalf of a Holder shall be deemed valid unless challenged at or prior
to its exercise, and the burden of proving invalidity shall rest on the
challenger.  No proxy shall be valid more than three years after its date of
execution.

          SECTION 6.6.  Holder Action by Written Consent.

          Any action which may be taken by Holders at a meeting may be taken
without a meeting if Holders holding at least a Majority in Liquidation Amount
of all Trust Securities entitled to vote in respect of such action (or such
larger proportion thereof as shall be required by any other provision of this
Trust Agreement) shall consent to the action in writing.

          SECTION 6.7.  Record Date for Voting and Other Purposes.

          For the purposes of determining the Holders who are entitled to notice
of and to vote at any meeting or by written consent, or to participate in any
distribution on the Trust Securities in respect of which a record date is not
otherwise provided for in this Trust Agreement, or for the purpose of any other
action, the Administrators or Property Trustee may from time to time fix a date,
not more than 90 days prior to the date of any meeting of Holders or the payment
of a distribution or other action, as the case may be, as a record date for the
determination of the identity of the Holders of record for such purposes.

          SECTION 6.8.  Acts of Holders.

          Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Trust Agreement to be given, made
or taken by Holders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Holders in person or by an agent
duly

                                       26
<PAGE>
 
appointed in writing; and, except as otherwise expressly provided herein, such
action shall become effective when such instrument or instruments are delivered
to the Property Trustee.  Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments.  Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Trust Agreement and (subject to Section 8.1)
conclusive in favor of the Issuer Trustees, if made in the manner provided in
this Section.

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

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

          Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Trust Security shall bind every future Holder
of the same Trust Security and the Holder of every Trust 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 Issuer
Trustees, the Administrators or the Issuer Trust in reliance thereon, whether or
not notation of such action is made upon such Trust Security.

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

          If any dispute shall arise among the Holders, the Administrators or
the Issuer Trustees with respect to the authenticity, validity or binding nature
of any request, demand, authorization, direction, consent, waiver or other Act
of such Holder or Issuer Trustee under this Article VI, then the determination
of such matter by the Property Trustee shall be conclusive with respect to such
matter.

          SECTION 6.9.  Inspection of Records.

          Upon reasonable notice to the Administrators and the Property Trustee,
the records of the Issuer Trust shall be open to inspection by Holders during
normal business hours for any purpose reasonably related to such Holder's
interest as a Holder.

                                 ARTICLE VIII

                    THE ISSUER TRUSTEES; THE ADMINISTRATORS

          SECTION 8.1.  Certain Duties and Responsibilities.

          (a) The duties and responsibilities of the Issuer Trustees and the
Administrators shall be as provided by this Trust Agreement and, in the case of
the Property Trustee, by the Trust Indenture Act.  Notwithstanding the
foregoing, no provision of this Trust Agreement shall require the Issuer
Trustees or the Administrators to expend or risk their own funds or otherwise
incur any financial liability in the performance of any of their duties
hereunder, or in the exercise of any of their rights or powers, if they shall
have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.
Whether or not therein expressly so provided, every provision of this Trust
Agreement relating to the conduct or affecting the liability of or affording
protection to the Issuer Trustees or the Administrators shall be subject to the
provisions of this Section.  Nothing in this Trust Agreement shall be construed
to release an Administrator from liability for its own grossly negligent action,
its own grossly negligent failure to act, or its own willful misconduct.  To the
extent that, at law or in equity, an Issuer Trustee or Administrator has duties
and liabilities relating to the Issuer Trust or to the Holders, such Issuer
Trustee or Administrator shall not be liable to the Issuer Trust or to any
Holder for such Issuer Trustee's or Administrator's good faith reliance on the
provisions of this Trust Agreement.  The provisions of this Trust Agreement, to
the extent that they restrict the duties and liabilities of the Issuer Trustees
and Administrators otherwise existing at law or in equity, are agreed by the
Depositor and the Holders to replace such other duties and liabilities of the
Issuer Trustees and Administrators.

          (b) All payments made by the Property Trustee or a Paying Agent in
respect of the Trust Securities shall be made only from the revenue and proceeds
from the Trust Property and only to the extent that there shall be sufficient
revenue or proceeds from the Trust Property to enable the Property Trustee or a
Paying Agent to make payments in accordance with the terms hereof.  Each Holder,
by its acceptance of a Trust Security, agrees that it will look solely to the
revenue and proceeds from the Trust Property to the extent legally available for
distribution to it as herein provided and that neither the Issuer Trustees nor
the Administrators are personally liable to it for any amount distributable in
respect of any Trust Security or for any other liability in respect of any Trust
Security.  This Section 8.1(b) does not limit the liability of the Issuer
Trustees expressly set forth elsewhere in this Trust Agreement or, in the case
of the Property Trustee, in the Trust Indenture Act.

          (c) The Property Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Trust Agreement (including pursuant to Section 10.10), and no implied
covenants shall be read into this Trust Agreement against the Property Trustee.
If an Event of Default has occurred (that has not been cured or waived pursuant
to Article V of the Indenture), the Property Trustee shall enforce this Trust
Agreement for the benefit of the Holders and shall exercise such of the rights
and powers vested in it by this Trust Agreement, and use the same degree of care
and skill in its exercise thereof, as a prudent person would exercise or use
under the circumstances in the conduct of his or her own affairs.

          (d) No provision of this Trust Agreement shall be construed to relieve
the Property Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

          (i) prior to the occurrence of any Event of Default and after the
     curing or waiving of all such Events of Default that may have occurred:

               (A) the duties and obligations of the Property Trustee shall be
          determined solely by the express provisions of this Trust Agreement
          (including pursuant to Section 10.10), and the Property Trustee shall
          not be liable except for the performance of such duties and

                                       29
<PAGE>
 
          obligations as are specifically set forth in this Trust Agreement
          (including pursuant to Section 10.10); and

               (B) in the absence of bad faith on the part of the Property
          Trustee, the Property Trustee may conclusively rely, as to the truth
          of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the Property
          Trustee and conforming to the requirements of this Trust Agreement;
          but in the case of any such certificates or opinions that by any
          provision hereof or of the Trust Indenture Act are specifically
          required to be furnished to the Property Trustee, the Property Trustee
          shall be under a duty to examine the same to determine whether or not
          they conform to the requirements of this Trust Agreement;

          (ii) the Property Trustee shall not be liable for any error of
     judgment made in good faith by an authorized officer of the Property
     Trustee, unless it shall be proved that the Property Trustee was negligent
     in ascertaining the pertinent facts;

          (iii)  the Property 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 at least a Majority in Liquidation Amount
     of the Capital Securities relating to the time, method and place of
     conducting any proceeding for any remedy available to the Property Trustee,
     or exercising any trust or power conferred upon the Property Trustee under
     this Trust Agreement;

          (iv) the Property Trustee's sole duty with respect to the custody,
     safe keeping and physical preservation of the Junior Subordinated
     Debentures and the Payment Account shall be to deal with such property in a
     similar manner as the Property Trustee deals with similar property for its
     own account, subject to the protections and limitations on liability
     afforded to the Property Trustee under this Trust Agreement and the Trust
     Indenture Act;

          (v) the Property Trustee shall not be liable for any interest on any
     money received by it except as it may otherwise agree with the Depositor;
     and money held by the Property Trustee need not be segregated from other
     funds held by it except in relation to the Payment Account maintained by
     the Property Trustee pursuant to Section 3.1 and except to the extent
     otherwise required by law;

          (vi) the Property Trustee shall not be responsible for monitoring the
     compliance by the Administrators or the Depositor with their respective
     duties under this Trust Agreement, nor shall the Property Trustee be liable
     for the default or misconduct of any other Issuer Trustee, the
     Administrators or the Depositor; and

          (vii)  no provision of this Trust Agreement shall require the Property
     Trustee to expend or risk its own funds or otherwise incur personal
     financial liability in the performance of any of its duties or in the
     exercise of any of its rights or powers, if the Property Trustee shall have
     reasonable grounds for believing that the repayment of such funds or
     liability is not reasonably assured to it under the terms of this Trust
     Agreement or adequate indemnity against such risk or liability is not
     reasonably assured to it.

     (e) The Administrators shall not be responsible for monitoring the
compliance by the Issuer Trustees or the Depositor with their respective duties
under this Trust Agreement, nor shall either Administrator be liable for the
default or misconduct of any other Administrator, the Issuer Trustees or the
Depositor.

     SECTION 8.2.  Certain Notices.

     Within ten Business Days after the occurrence of any Event of Default
actually known to a Responsible Officer of the Property Trustee, the Property
Trustee shall transmit, in the manner and to the extent provided in Section
10.8, notice of such Event of Default to the Holders and the Administrators,
unless such Event of Default shall have been cured or waived.

     Within ten Business Days after the receipt of notice of the Depositor's
exercise of its right to defer the payment of interest on the Junior
Subordinated Debentures pursuant to the Indenture, the Property Trustee shall
transmit, in the manner and to the extent provided in Section 10.8, notice of
such exercise to the Holders and the Administrators, unless such exercise shall
have been revoked.

     SECTION 8.3.  Certain Rights of Property Trustee.

     Subject to the provisions of Section 8.1:

     (a) the Property Trustee may conclusively rely and shall be fully protected
in acting or refraining from acting in good faith upon any resolution, Opinion
of Counsel, certificate, written representation of a Holder or transferee,
certificate of auditors or any other certificate, statement, instrument,
opinion, report, notice, request, consent, order, appraisal, bond, debenture,

parties;

     (b) any direction or act of the Depositor contemplated by this Trust
Agreement shall be sufficiently evidenced by an Officer's Certificate;

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

     (d) the Property Trustee may consult with counsel of its own choosing
(which counsel may be counsel to the Depositor or any of its Affiliates, and may
include any of its employees) and the advice of such counsel shall be full and
complete authorization and protection in respect of any action taken suffered or
omitted by it hereunder in good faith and in reliance thereon and in accordance
with such advice, such counsel may be counsel to the Depositor or any of its
Affiliates, and may include any of its employees; the Property Trustee shall
have the right at any time to seek instructions concerning the administration of
this Trust Agreement from any court of competent jurisdiction;

     (e) the Property Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the Holders pursuant to this Trust Agreement, unless such
Holders shall have offered to the Property Trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction; provided, that
nothing contained in this Section 8.3(e) shall be taken to relieve the Property
Trustee, upon the occurrence of an Event of Default, of its obligation to
exercise the rights and powers vested in it by this Trust Agreement;

     (f) the Property Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,

     (g) the Property Trustee may execute any of the trusts or powers hereunder
or perform any of its duties hereunder either directly or by or through its
agents or attorneys, provided that the Property Trustee shall not be responsible
for any misconduct or negligence on the part of any agent or attorney appointed
with due care by it hereunder;

     (h) whenever in the administration of this Trust Agreement the Property
Trustee shall deem it desirable to receive instructions with respect to
enforcing any remedy or right or taking any other action hereunder, the Property
Trustee (i) may request instructions from the Holders (which instructions may
only be given by the Holders of the same proportion in Liquidation Amount of the
Trust Securities as would be entitled to direct the Property Trustee under the
terms of the Trust Securities in respect of such remedy, right or action), (ii)
may refrain from enforcing such remedy or right or taking such other action
until such instructions are received, and (iii) shall be fully protected in
acting in accordance with such instructions;

     (i) except as otherwise expressly provided by this Trust Agreement, the
Property Trustee shall not be under any obligation to take any action that is
discretionary under the provisions of this Trust Agreement.  No provision of
this Trust Agreement shall be deemed to impose any duty or obligation on any
Issuer Trustee or Administrator to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any

construing any of the provisions of this Trust Agreement the Property Trustee
finds the same ambiguous or inconsistent with any other provisions contained
herein or (iii) the Property Trustee is unsure of the application of any
provision of this Trust Agreement, then, except as to any matter as to which the
Holders are entitled to vote under the terms of this Trust Agreement, the
Property Trustee shall deliver a notice to the Depositor requesting written
instructions of the Depositor as to the course of action to be taken and the
Property Trustee shall take such action, or refrain from taking such action, as
the Property Trustee shall be instructed in writing to take, or to refrain from
taking, by the Depositor; provided, however, that if the Property Trustee does
not receive such instructions of the Depositor within ten Business Days after it
has delivered such notice, or such reasonably shorter period of time set forth
in such notice (which to the extent practicable shall not be less than two
Business Days), it may, but shall be under no duty to, take or refrain from
taking such action not inconsistent with this Trust Agreement as it shall deem
advisable and in the best interests of the Holders, in which event the Property
Trustee shall have no liability except for its own bad faith, negligence or
willful misconduct;

     (k) whenever in the administration of this Trust Agreement, the Property
Trustee shall deem it desirable that a matter be established before undertaking,
suffering or omitting any action hereunder, the Property Trustee (unless other
evidence is herein specifically prescribed) may, in the absence of bad faith on
its part, request and conclusively rely upon an Officer's Certificate which,
upon receipt of such request, shall be promptly delivered by the Depositor or
the Administrator;

     (l) when the Property Trustee incurs expenses or renders services in
connection with a Bankruptcy Event, such expenses (including the fees and
expenses of its counsel) and the compensation for such services are intended to
constitute expenses of administration under any bankruptcy law or law relating
to creditors rights generally; and

     (m) the Property Trustee shall not be charged with knowledge of an Event of

failure to act of the Property Trustee, a Responsible Officer of the Property
Trustee obtains actual knowledge of such event or the Property Trustee receives
written

                                       32

notice of such event from Securityholders at least 25% of the outstanding Trust
Securities (based upon Liquidation Amount).

     SECTION 8.4.  Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Trust Securities Certificates
shall be taken as the statements of the Issuer Trust, and the Issuer Trustees
and the Administrators do not assume any responsibility for their correctness.
The Issuer Trustees and the Administrators shall not be accountable for the use
or application by the Depositor of the proceeds of the Junior Subordinated
Debentures.

     SECTION 8.5.  May Hold Securities.

     The Administrators, any Issuer Trustee or any other agent of any Issuer
Trustee or the Issuer Trust, in its individual or any other capacity, may become
the owner or pledgee of Trust Securities and, subject to Sections 8.8 and 8.13,
and except as provided in the definition of the term "Outstanding" in Article I,
may otherwise deal with the Issuer Trust with the same rights it would have if
it were not an Administrator, Issuer Trustee or such other agent.

     SECTION 8.6.  Compensation; Indemnity; Fees.

     The Depositor, as borrower, agrees:

     (a) to pay to the Issuer Trustees from time to time such reasonable
compensation for all services rendered by them hereunder as the parties shall
agree from time to time (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust);

     (b) to reimburse the Issuer Trustees upon request for all reasonable
expenses, disbursements and advances incurred or made by the Issuer Trustees in
accordance with any provision of this Trust Agreement (including the reasonable
compensation and the expenses and disbursements of its agents and counsel),
except any such expense, disbursement or advance as may be attributable to their
negligence or willful misconduct; and

     (c)  to the fullest extent permitted by applicable law, to indemnify and
hold harmless (i) each Issuer Trustee, (ii) each Administrator, (iii) any
Affiliate of any Issuer Trustee, (iv) any officer, director, shareholder,
employee, representative or agent of any Issuer Trustee, and (v) any employee or
agent of the Issuer Trust, (referred to herein as an "Indemnified Person") from
and against any loss, damage, liability, tax, penalty, expense or claim of any
kind or nature whatsoever incurred by such Indemnified Person arising out of or
in connection with the creation, operation or dissolution of the Issuer Trust or
any act or omission performed or omitted by such Indemnified Person in good
faith on behalf of the Issuer Trust and in a manner such Indemnified Person
reasonably believed to be within the scope of authority conferred on such
Indemnified Person by this Trust Agreement, except that no Indemnified Person
(other than an Administrator) shall be entitled to be indemnified in respect of
any loss, damage or claim incurred by such Indemnified Person by reason of
negligence or willful misconduct with respect to such acts or omissions, and
further provided that no Administrator shall be entitled to be indemnified in
respect of any loss, damage or claim incurred by such Administrator by reason of
gross negligence or willful misconduct with respect to such acts or omissions.

     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement or the earlier resignation or removal of any Issuer Trustee.

     No Issuer Trustee may claim any lien or charge on any Trust Property as a
result of any amount due pursuant to this Section 8.6.

     The Depositor, any Administrator and any Issuer Trustee (subject to Section
8.8) may engage in or possess an interest in other business ventures of any
nature or description, independently or with others, similar or dissimilar to
the business of the Issuer Trust, and the Issuer Trust and the Holders of Trust
Securities shall have no rights by virtue of this Trust Agreement in and to such
independent ventures or the income or profits derived therefrom, and the pursuit
of any such venture, even if competitive with the business of the Issuer Trust,
shall not be deemed wrongful or improper.  Neither the Depositor, any
Administrator, nor any Issuer Trustee shall be obligated to present any
particular investment or other opportunity to the Issuer Trust even if such
opportunity is of a character that, if presented to the Issuer Trust, could be
taken by the Issuer Trust, and the Depositor, any Administrator or any Issuer
Trustee shall have the right to take for its own account (individually or as a
partner or fiduciary) or to recommend to others any such particular investment
or other opportunity.  Any Issuer Trustee may engage or be interested in any
financial or other transaction with the Depositor or any Affiliate of the
Depositor, or may act as depository for, trustee or agent for, or act on any
committee or body of holders of, securities or other obligations of the
Depositor or its Affiliates.

     In the event that the Property Trustee is also acting as Paying Agent or
Securities Registrar hereunder, the rights and protections afforded to the
Property Trustee pursuant to this Article VIII shall also be afforded to such
Paying Agent or Securities Registrar.

     SECTION 8.7.  Corporate Property Trustee Required; Eligibility of Trustees
and Administrators.

     (a) There shall at all times be a Property Trustee hereunder with respect
to the Trust Securities.  The Property Trustee shall be a Person that is a
national- or state-chartered bank and eligible pursuant to the Trust Indenture
Act to act as such and has a combined capital and surplus of at least
$50,000,000.  If any such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of its supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  If at any time
the Property Trustee with respect to the Trust Securities 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.

     (b) There shall at all times be one or more Administrators hereunder.  Each
Administrator shall be either a natural person who is at least 21 years of age
or a legal entity that shall act through one or more persons authorized to bind
that entity.  An employee, officer or Affiliate of the Depositor may serve as an
Administrator.

     (c) There shall at all times be a Delaware Trustee.  The Delaware Trustee
shall either be (i) a natural person who is at least 21 years of age and a
resident of the State of Delaware or (ii) a legal entity with its principal
place of business in the State of Delaware and that otherwise meets the
requirements of applicable Delaware law that shall act through one or more
persons authorized to bind such entity.

     SECTION 8.8.  Conflicting Interests.

     (a) If the Property Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement.

     (b) The Guarantee Agreement and the Indenture shall be deemed to be
sufficiently described in this Trust Agreement for the purposes of clause (i) of
the first proviso contained in Section 310(b) of the Trust Indenture Act.

                                       34

     SECTION 8.9.  Co-Trustees and Separate Trustee.

     Unless an Event of Default shall have occurred and be continuing, at
anytime or times, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the Trust Property may
at the time be located, the Property Trustee shall have power to appoint, and
upon the written request of the Property Trustee, the Depositor and the
Administrators shall for such purpose join with the Property Trustee in the
execution, delivery, and performance of all instruments and agreements necessary
or proper to appoint, one or more Persons approved by the Property Trustee
either to act as co-trustee, jointly with the Property Trustee, of all or any
part of such Trust Property, or to the extent required by law to act as separate
trustee of any such property, 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.  Any co-trustee or
separate trustee appointed pursuant to this Section shall either be (i) a
natural person who is at least 21 years of age and a resident of the United
States or (ii) a legal entity with its principal place of business in the United
States that shall act through one or more persons authorized to bind such
entity.

     Should any written instrument from the Depositor be required by any co-
trustee or separate trustee so appointed for more fully confirming 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 Depositor.

     Every co-trustee or separate trustee shall, to the extent permitted bylaw,
but to such extent only, be appointed subject to the following terms, namely:

     (a) The Trust Securities shall be executed by one or more Administrators,
and the Trust Securities shall be authenticated by the manual signature of the
Property Trustee 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 Property
Trustees specified hereunder, shall be exercised, solely by the Property Trustee
and not by such co-trustee or separate trustee.

     (b) The rights, powers, duties, and obligations hereby conferred or imposed
upon the Property Trustee in respect of any property covered by such appointment
shall be conferred or imposed upon and exercised or performed by the Property
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 Property 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.

     (c) The Property Trustee at any time, by an instrument in writing executed
by it, with the written concurrence of the Depositor, may accept the resignation
of or remove any co-trustee or separate trustee appointed under this Section,
and, in case a Debenture Event of Default has occurred and is continuing, the
Property Trustee shall have power to accept the resignation of, or remove, any
such co-trustee or separate trustee without the concurrence of the Depositor.
Upon the written request of the Property Trustee, the Depositor shall join with
the Property Trustee in the execution, delivery and performance 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 Property Trustee or any other trustee
hereunder.

     (e) The Property Trustee shall not be liable by reason of any act of a co-
trustee or separate trustee or any employees or agents of a co-trustee and
separate trustee nor shall it be liable for the supervision of a co-trustee or
separate trustee or employees or agents of a co-trustee and separate trustee.

                                       35
<PAGE>
 
     (f) Any Act of Holders delivered to the Property Trustee shall be deemed to
have been delivered to each such co-trustee and separate trustee.

     SECTION 8.10.  Resignation and Removal; Appointment of Successor.

     No resignation or removal of any Issuer Trustee (the "Relevant Trustee")
and no appointment of a successor Issuer Trustee pursuant to this Article shall
become effective until the acceptance of appointment by the successor Issuer
Trustee in accordance with the applicable requirements of Section 8.11.

     Subject to the immediately preceding paragraph, a Relevant Trustee may
resign at any time by giving written notice thereof to the Holders.  The
Relevant Trustee shall appoint a successor by requesting from at least three
Persons meeting the eligibility requirements its expenses and charges to serve
as the Relevant Trustee on a form provided by the Administrators, and selecting
the Person who agrees to the lowest expenses and charges.  If the instrument of
acceptance by the successor Issuer Trustee required by Section 8.11 shall not
have been delivered to the Relevant Trustee within 60 days after the giving of
such notice of resignation, the Relevant Trustee may petition, at the expense of
the Issuer Trust, any court of competent jurisdiction for the appointment of a
successor Relevant Trustee.

     The Property Trustee or the Delaware Trustee may be removed at any time by
Act of the Holders of at least a Majority in Liquidation Amount of the Capital
Securities, delivered to the Relevant Trustee (in its individual capacity and on
behalf of the Issuer Trust) (i) for cause, or (ii) if a Debenture Event of
Default shall have occurred and be continuing at any time.  If the instrument of
such removal shall not have been delivered to the Relevant Trustee within 60
days after such Act, the Relevant Trustee may petition, at the expense of the
Issuer Trust, any court of competent jurisdiction for appointment of a successor
Relevant Trustee.

     If any Issuer Trustee shall resign, it shall appoint its successor.  If a
resigning Issuer Trustee shall fail to appoint a successor, or if an Issuer
Trustee shall be removed or become incapable of acting as Issuer Trustee, or if
any vacancy shall occur in the office of any Issuer Trustee for any cause, the
Holders of the Capital Securities, by Act of the Holders of record of not less
than 25% in aggregate Liquidation Amount of the Capital Securities then
Outstanding delivered to such Relevant Trustee, shall promptly appoint a
successor Relevant Trustee or Trustees, and such successor Issuer Trustee shall
comply with the applicable requirements of Section 8.11.  If no successor
Relevant Trustee shall have been so appointed by the Holders of the Capital
Securities and accepted appointment in the manner required by Section 8.11, any
Holder, on behalf of himself and all others similarly situated, or any other
Issuer Trustee, may petition any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

     The Property Trustee shall give notice of each resignation and each removal
of an Issuer Trustee and each appointment of a successor Issuer Trustee to all
Holders in the manner provided in Section 10.8 and shall give notice to the
Depositor and to the Administrators.  Each notice shall include the name of the
successor Relevant Trustee and the address of its Corporate Trust Office if it
is the Property Trustee.

     Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Delaware Trustee who is a natural person dies or
becomes, in the opinion of the Holders of the Common Securities, incompetent or
incapacitated, the vacancy created by such death, incompetence or incapacity may
be filled by the Property Trustee following the procedures regarding expenses
and charges set forth above (with the successor in each case being a Person who
satisfies the eligibility requirements for Administrators or Delaware Trustee,
as the case may be, set forth in Section 8.7).

     SECTION 8.11.  Acceptance of Appointment by Successor.

     In case of the appointment hereunder of a successor Relevant Trustee, the
retiring Relevant Trustee and each such successor Relevant Trustee with respect
to the Trust Securities shall execute, acknowledge and deliver

                                       36
<PAGE>
 
an amendment hereto wherein each successor Relevant Trustee shall accept such
appointment and which (a) shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, each successor Relevant
Trustee all the rights, powers, trusts and duties of the retiring Relevant
Trustee with respect to the Trust Securities and the Issuer Trust, and (b) shall
add to or change any of the provisions of this Trust Agreement as shall be
necessary to provide for or facilitate the administration of the Issuer Trust by
more than one Relevant Trustee and upon the execution and delivery of such
amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Relevant Trustee; but,
on request of the Issuer Trust or any successor Relevant Trustee such retiring
Relevant Trustee shall, upon payment of its charges, duly assign, transfer and
deliver to such successor Relevant Trustee all Trust Property, all proceeds
thereof and money held by such retiring Relevant Trustee hereunder with respect
to the Trust Securities and the Issuer Trust.

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

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

     SECTION 8.12.  Merger, Conversion, Consolidation or Succession to Business.

     Any Person into which an Issuer Trustee may be merged or converted or with
which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which such Issuer Trustee shall be a party, or
any Person succeeding to all or substantially all the corporate trust business
of such Issuer Trustee, shall be the successor of such Issuer Trustee hereunder,
provided that such Person 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.

     SECTION 8.13.  Preferential Collection of Claims Against Depositor or
Issuer Trust.

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

     SECTION 8.14.  Trustee May File Proofs of Claim.

     In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other similar judicial
proceeding relative to the Issuer Trust or any other obligor upon the Trust
Securities or the property of the Issuer Trust or of such other obligor, the
Property Trustee (irrespective of whether any Distributions on the Trust
Securities shall then be due and payable and irrespective of whether the
Property Trustee shall have made any demand on the Issuer Trust for the payment
of any past due Distributions) shall be entitled and empowered, to the fullest
extent permitted by law, by intervention in such proceeding or otherwise:

     (a) to file and prove a claim for the whole amount of any Distributions
owing and unpaid in respect of the Trust Securities and to file such other
papers or documents as may be necessary or advisable in order to have the claims
of the Property Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Property Trustee, its agents and
counsel) and of the Holders allowed in such judicial proceeding, and

                                       37
<PAGE>
 
     (b) to collect and receive any monies 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 Property Trustee and, in the event the Property Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Property Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Property Trustee, its agents and counsel, and
any other amounts due the Property Trustee.

     Nothing herein contained shall be deemed to authorize the Property Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or compensation affecting the Trust
Securities or the rights of any Holder thereof or to authorize the Property
Trustee to vote in respect of the claim of any Holder in any such proceeding.

     SECTION 8.15.  Reports by Property Trustee.

     (a) Not later than May 15 of each year commencing with May 15, 1998, the
Property Trustee shall provide to the Holders of the Trust Securities such
reports as are required by Section 313 of the Trust Indenture Act, if any, in
the form, in the manner and at the times provided by Section 313 of the Trust
Indenture Act.  The Property Trustee shall also comply with the requirements of
Section 313(d) of the Trust Indenture Act.

     (b) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with the Depositor.

     SECTION 8.16.  Reports to the Property Trustee.

     Each of the Depositor and the Administrators on behalf of the Issuer Trust
shall provide to the Property Trustee, the Commission and the Holders of the
Trust Securities, as applicable, such documents, reports and information as
required by Section 314(a)(1) - (3) (if any) of the Trust Indenture Act and the
compliance certificates required by Section 314(a)(4) and (c) of the Trust
Indenture Act (provided that any certificate to be provided pursuant to Section
314(a)(4) of the Trust Indenture Act shall be provided within 120 days of the
end of each fiscal year of the Issuer Trust).

     SECTION 8.17.  Evidence of Compliance with Conditions Precedent.

     Each of the Depositor and the Administrators on behalf of the Issuer Trust
shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement which relate
to any of the matters set forth in Section 314(c) of the Trust Indenture Act.
Any certificate or opinion required to be given pursuant to Section 314(c) shall
comply with Section 314(e) of the Trust Indenture Act.

     SECTION 8.18.  Number of Issuer Trustees.

     (a) The number of Issuer Trustees shall be two.  The Property Trustee and
the Delaware Trustee may be the same Person, in which case the number of Issuer
Trustees may be one.

     (b) If an Issuer Trustee ceases to hold office for any reason, a vacancy
shall occur.  The vacancy shall be filled with an Issuer Trustee appointed in
accordance with Section 8.10.

     (c) The death, resignation, retirement, removal, bankruptcy, dissolution,
termination, incompetence or incapacity to perform the duties of an Issuer
Trustee shall not operate to dissolve, terminate or annul the Issuer Trust or
terminate this Trust Agreement.

     SECTION 8.19.  Delegation of Power.

     (a) Any Administrator may, by power of attorney consistent with applicable
law, delegate to any other natural person over the age of 21 his or her power
for the purpose of executing any documents contemplated in Section 2.7(a) or
making any governmental filing; and

     (b) The Administrators shall have power to delegate from time to time to
such of their number the doing of such things and the execution of such
instruments either in the name of the Issuer Trust or the names of the
Administrators or otherwise as the Administrators may deem expedient, to the
extent such delegation is not prohibited by applicable law or contrary to the
provisions of this Trust Agreement.

     SECTION 8.20.  Appointment of Administrators.

     (a) The Administrators shall be appointed by the Holders of a Majority in
Liquidation Amount of the Common Securities and may be removed by the Holders of
a Majority in Liquidation Amount of the Common Securities or may resign at
anytime.  Upon any resignation or removal, the Depositor shall appoint a
successor Administrator.  Each Administrator shall execute this Trust Agreement
thereby agreeing to comply with, and be legally bound by, all of the terms,
conditions and provisions of this Trust Agreement.  If at any time there is no
Administrator, the Property Trustee or any Holder who has been a Holder of Trust
Securities for at least six months may petition any court of competent
jurisdiction for the appointment of one or more Administrators.

     (b) Whenever a vacancy in the number of Administrators shall occur, until
such vacancy is filled by the appointment of an Administrator in accordance with
this Section 8.20, the Administrators in office, regardless of their number (and
notwithstanding any other provision of this Trust Agreement), shall have all the
powers granted to the Administrators and shall discharge all the duties imposed
upon the Administrators by this Trust Agreement.

     (c) Notwithstanding the foregoing, or any other provision of this Trust
Agreement, in the event any Administrator or a Delaware Trustee who is a natural
person dies or becomes, in the opinion of the Holders of a Majority in
Liquidation Amount of the Common Securities, incompetent, or incapacitated, the
vacancy created by such death, incompetence or incapacity may be filled by the
remaining Administrators, if there were at least two of them prior to such
vacancy, and by the Depositor, if there were not two such Administrators
immediately prior to such vacancy (with the successor in each case being a

                                  ARTICLE IX

                      DISSOLUTION, LIQUIDATION AND MERGER

     SECTION 9.1.  Dissolution Upon Expiration Date.

     Unless earlier dissolved, the Issuer Trust shall automatically dissolve on
March 12, 2039 (the "Expiration Date"), and thereafter the Trust Property shall
be distributed in accordance with Section 9.4.

     SECTION 9.2.  Early Termination.

     The first to occur of any of the following events is an "Early Termination
Event" and the occurrence of which shall cause the dissolution of the Issuer
Trust:

                                       39
<PAGE>
 
     (a) the occurrence of the appointment of a receiver or other similar
official in any liquidation, insolvency or similar proceeding with respect to
the Depositor or all or substantially all of its property, or a court or other
governmental agency shall enter a decree or order and such decree or order shall
remain unstayed and undischarged for a period of 60 days, unless the Depositor
shall transfer the Common Securities as provided by Section 5.11, in which case
this provision shall refer instead to any such successor Holder of the Common
Securities;

     (b) the written direction to the Property Trustee from the Holder of the
Common Securities at any time to dissolve the Issuer Trust and to distribute a
Like Amount of the Junior Subordinated Debentures to Holders in exchange for the
Capital Securities (which direction, subject to Section 9.4(a), is optional and
wholly within the discretion of the Holders of the Common Securities);

     (c) the redemption of all of the Capital Securities in connection with the
redemption of all the Junior Subordinated Debentures; and

     (d) the entry of an order for dissolution of the Issuer Trust by a court of
competent jurisdiction.

     SECTION 9.3.  Termination.

     As soon as is practicable after the occurrence of an event referred to in
Section 9.1 or 9.2, and upon the completion of the winding up and liquidation of
the Issuer Trust, the Administrators and the Issuer Trustees (each of whom is
hereby authorized to take such action) shall file a certificate of cancellation
with the Secretary of State of the State of Delaware terminating the Trust and,
upon such filing, the respective obligations and responsibilities of the Issuer
Trustees, the Administrators and the Issuer Trust shall terminate.

     SECTION 9.4.  Liquidation.

     (a) If an Early Termination Event specified in clause (a), (b) or (d) of
Section 9.2 occurs or upon the Expiration Date, the Issuer Trust shall be wound
up and liquidated by the Property Trustee as expeditiously as the Property
Trustee determines to be possible by distributing, after paying or making
reasonable provision to pay all claims and obligations of the Issuer Trust in
accordance with Section 3808(e) of the Delaware Business Trust Act, to each
Holder a Like Amount of Junior Subordinated Debentures, subject to Section
9.4(d).  Notice of liquidation shall be given by the Property Trustee by first-
class mail, postage prepaid, mailed not later than 15 nor more than 45 days
prior to the Liquidation Date to each Holder of Trust Securities at such
Holder's address appearing in the Securities Register.  All notices of
liquidation shall:

          (i)    state the Liquidation Date;

          (ii)   state that, from and after the Liquidation Date, the Trust
     Securities will no longer be deemed to be Outstanding and any Trust
     Securities Certificates not surrendered for exchange will be deemed to
     represent a Like Amount of Junior Subordinated Debentures; and

          (iii)  provide such information with respect to the mechanics by which
     Holders may exchange Trust Securities Certificates for Junior Subordinated
     Debentures, or if Section 9.4(d) applies receive a Liquidation
     Distribution, as the Administrators or the Property Trustee shall deem
     appropriate.

     (b) Except where Section 9.2(c) or 9.4(d) applies, in order to effect the
liquidation of the Issuer Trust and distribution of the Junior Subordinated
Debentures to Holders, the Property Trustee shall establish a record date for
such distribution (which shall be not more than 30 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish

                                       40
<PAGE>
 
such procedures as it shall deem appropriate to effect the distribution of
Junior Subordinated Debentures in exchange for the Outstanding Trust Securities
Certificates.

     (c) Except where Section 9.2(c) or 9.4(d) applies, after the Liquidation
Date, (i) the Capital Securities will no longer be deemed to be Outstanding,
(ii) the Clearing Agency for the Capital Securities or its nominee, as the
registered holder of the Global Capital Securities Certificate, shall receive a
registered global certificate or certificates representing the Junior
Subordinated Debentures to be delivered upon such distribution with respect to
Capital Securities held by the Clearing Agency or its nominee, and, (iii) any
Capital Securities Certificates not held by the Clearing Agency for the Capital
Securities or its nominee as specified in clause (ii) above will be deemed to
represent Junior Subordinated Debentures having a principal amount equal to the
stated Liquidation Amount of the Capital Securities represented thereby and
bearing accrued and unpaid interest in an amount equal to the accumulated and
unpaid Distributions on such Capital Securities until such certificates are
presented to the Securities Registrar for transfer or reissuance.

     (d) If, notwithstanding the other provisions of this Section 9.4, whether
because of an order for dissolution entered by a court of competent jurisdiction
or otherwise, distribution of the Junior Subordinated Debentures is not
practical, or if any Early Termination Event specified in clause (c) of Section
9.2 occurs, the Issuer Trust shall be dissolved and wound up and the Trust
Property shall be liquidated by the Property Trustee in such manner as the
Property Trustee determines.  In such event, on the date of the dissolution of
the Issuer Trust, unless the Trust Securities have been redeemed or are to be
redeemed on such date pursuant to Article IV, Holders will be entitled to
receive out of the assets of the Issuer Trust available for distribution to
Holders, after paying or making reasonable provision to pay all claims and
obligations of the Issuer Trust in accordance with Section 3808(e) of the
Delaware Business Trust Act, an amount equal to the aggregate of Liquidation
Amount per Trust Security plus accumulated and unpaid Distributions thereon to
the date of payment (such amount being the "Liquidation Distribution").  If,
upon any such dissolution, the Liquidation Distribution can be paid only in part
because the Issuer Trust has insufficient assets available to pay in full the
aggregate Liquidation Distribution, then, subject to the next succeeding
sentence, the amounts payable by the Issuer Trust on the Trust Securities shall
be paid on a pro rata basis (based upon Liquidation Amounts).  The Holders of
the Common Securities will be entitled to receive Liquidation Distributions upon
any such dissolution pro rata (determined as aforesaid) with Holders of Capital
Securities, except that, if a Debenture Event of Default has occurred and is
continuing as a result of any failure by the Company to pay any amounts in
respect of Junior Subordinated Debentures when due, the Capital Securities shall
have a priority over the Common Securities as provided in Section 4.3.

     SECTION 9.5.  Mergers, Consolidations, Amalgamations or Replacements of the
Issuer Trust.

     The Issuer Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, any entity, except pursuant to this Section 9.5
or Section 9.4.  At the request of the Holders of the Common Securities, and
with the consent of the Holders of at least a Majority in Liquidation Amount of
the Capital Securities, the Issuer Trust may merge with or into, consolidate,
amalgamate, or be replaced by or convey, transfer or lease its properties and
assets substantially as an entirety to a trust organized as such under the laws
of any State; provided, however, that (i) such successor entity either (a)
expressly assumes all of the obligations of the Issuer Trust with respect to the
Capital Securities or (b) substitutes for the Capital Securities other
securities having substantially the same terms as the Capital Securities
(the"Successor Securities") so long as the Successor Securities have the same
priority as the Capital Securities with respect to distributions and payments
upon liquidation, redemption and otherwise, (ii) a trustee of such successor
entity possessing the same powers and duties as the Property Trustee is
appointed to hold the Junior Subordinated Debentures, (iii) such merger,
consolidation, amalgamation,replacement, conveyance, transfer or lease does not
cause the Capital Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization, (iv)
such merger, consolidation, amalgamation, replacement, conveyance, transfer or
lease does not adversely affect the rights, preferences and privileges of the
holders of the Capital Securities (including any Successor Securities) in any
material respect,

                                       41
<PAGE>
 
(v) such successor entity has a purpose substantially identical to that of the
Issuer Trust, (vi) prior to such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, the Issuer Trustee has received an
Opinion of Counsel from independent counsel experienced in such matters to the
effect that (a) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights preferences
and privileges of the holders of the Capital Securities (including any Successor
Securities) in any material respect, and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, neither
the Issuer Trust nor such successor entity will be required to register as
an"investment company" under the Investment Company Act and (vii) the Depositor
or any permitted transferee to whom it has transferred the Common Securities
hereunder own all of the common securities of such successor entity and
guarantees the obligations of such successor entity under the Successor
Securities at least to the extent provided by the Guarantee Agreement.
Notwithstanding the foregoing, the Issuer Trust shall not, except with the
consent of holders of 100% in Liquidation Amount of the Capital Securities,
consolidate, amalgamate, merge with or into, or be replaced by or convey,
transfer or lease its properties and assets substantially as an entirety to any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger, replacement,
conveyance, transfer or lease would cause the Issuer Trust or the successor
entity to be taxable as a corporation for United States Federal income tax
purposes.

Securities, without the consent of any Holder of the Capital Securities (i) to
cure any ambiguity, correct or supplement any provision herein which may be
inconsistent with any other provision herein, or to make any other provisions
with respect to matters or questions arising under this Trust Agreement,
provided, however, that such amendment shall not adversely affect in any
material respect the interests of any Holder or (ii) to modify, eliminate or add

Outstanding or to ensure that the Issuer Trust will not be required to register
as an investment company under the Investment Company Act.

     (b) Except as provided in Section 10.2(c) hereof, any provision of this
Trust Agreement may be amended by the Property Trustee and the Holders of a
Majority in Liquidation Amount of the Common Securities with (i) the consent of
Holders of at least a Majority in Liquidation Amount of the Capital Securities
and (ii) receipt by the Issuer Trustees of an Opinion of Counsel to the effect
that such amendment or the exercise of any power granted to the Issuer Trustees
in accordance with such amendment will not cause the

                                       42
<PAGE>
 
Issuer Trust to be taxable as a corporation for United States federal income tax
purposes or affect the Issuer Trust's exemption from status of an "investment
company" under the Investment Company Act.

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Holder, this Trust Agreement may
not be amended to (i) change the amount or timing of any Distribution on the

taxable as a corporation for United States Federal income tax purposes.

     (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor and the Administrators, this Trust

on the Depositor or the Administrators.

Administrators or the Property Trustee shall promptly provide to the Depositor a
copy of such amendment.

     (g) Neither the Property Trustee nor the Delaware Trustee shall be required
to enter into any amendment to this Trust Agreement which affects its own
rights, duties or immunities under this Trust Agreement.  The Property Trustee
shall be entitled to receive an Opinion of Counsel and an Officer's Certificate
stating that any amendment to this Trust Agreement is in compliance with this
Trust Agreement.

     (h) Any amendments to this Trust Agreement, pursuant to Section 10.2(a),
shall become effective when notice of such amendment is given to the Holders of
the Trust Securities.

     (i) Notwithstanding any other provision of this Trust Agreement, no
amendment to this Trust Agreement may be made if, as a result of such amendment,
it would cause the Issuer Trust to be taxable as a corporation for United States
Federal income tax purposes.

     SECTION 10.3.  Separability.

     In case any provision in this Trust Agreement or in the Trust Securities
Certificates shall be invalid, illegal or unenforceable, the validity, legality

                    AGREEMENT AS TO EXPENSES AND LIABILITIES


          AGREEMENT AS TO EXPENSES AND LIABILITIES, dated as of March 12, 1998,
between Morgan Stanley, Dean Witter, Discover & Co., a Delaware corporation, as

(the "Issuer Trust").

          WHEREAS, the Issuer Trust intends to issue its Common Securities (the

and sell 7.10% Capital Securities, (the "Capital Securities") with such powers,

terms used but not defined herein have the meanings set forth in the Trust
Agreement;

          NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:


                                   ARTICLE I

          SECTION 1.1.  Guarantee by the Depositor.  Subject to the terms and
conditions hereof, the Depositor hereby irrevocably and unconditionally
guarantees to each person or entity to whom the Issuer Trust is now or hereafter
becomes indebted or liable (the "Beneficiaries") the full payment, when and as
due, of any and all Obligations (as hereinafter defined) to such Beneficiaries.
As used herein, "Obligations" means any costs, expenses or liabilities of the
Issuer Trust, other than obligations of the Issuer Trust to pay to holders of
any Trust Securities the amounts due such holders pursuant to the terms of the
Trust Securities.  This Agreement is intended to be for the benefit of, and to
be enforceable by, all such Beneficiaries, whether or not such Beneficiaries
have received notice hereof.

          SECTION 1.2.  Subordination of Guarantee.  The guarantee and other
liabilities and obligations of the Depositor under this Agreement shall
constitute unsecured obligations of the Depositor and shall rank subordinate and
junior in right of payment to all Senior Indebtedness (as defined in the
Indenture) of the Depositor to the extent and in the manner set forth in the
Indenture with respect to the Debentures, and the provisions of Article XIII of
the Indenture will apply, mutatis mutandis, to the obligations of the Depositor
hereunder.  The obligations of the Depositor hereunder do not constitute Senior
Indebtedness (as defined in the Indenture) of the Depositor.

          SECTION 1.3.  Term of Agreement.  This Agreement shall terminate and
be of no further force and effect upon the dissolution of the Issuer Trust,
provided, however, that this Agreement shall continue to be effective or shall
be reinstated, as the case may be, if at any time any holder of Capital
Securities or any Beneficiary must restore payment of any sums paid under the
Capital Securities, under any Obligation, under the Guarantee Agreement dated
the date hereof by the Depositor and The Bank of New York, as guarantee

                                      E-1

trustee, or under this Agreement for any reason whatsoever.  This Agreement is
continuing, irrevocable, unconditional and absolute.

          SECTION 1.4.  Waiver of Notice.  The Depositor hereby waives notice of
acceptance of this Agreement and of any Obligation to which it applies or may
apply, and the Depositor hereby waives presentment, demand for payment, protest,
notice of nonpayment, notice of dishonor, notice of redemption and all other
notices and demands.

          SECTION 1.5.  No Impairment.  The obligations, covenants, agreements
and duties of the Depositor under this Agreement shall in no way be affected or
impaired by reason of the happening from time to time of any of the following:

          (a) the extension of time for the payment by the Issuer Trust of all
or any portion of the Obligations or for the performance of any other obligation
under, arising out of, or in connection with, the Obligations;

          (b) any failure, omission, delay or lack of diligence on the part of
the Beneficiaries to enforce, assert or exercise any right, privilege, power or
remedy conferred on the Beneficiaries with respect to the Obligations or any
action on the part of the Issuer Trust granting indulgence or extension of any
kind; or

          (c) the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,
or other similar proceedings affecting, the Issuer Trust or any of the assets of
the Issuer Trust (other than the dissolution of the Issuer Trust in accordance
with the terms thereof).

There shall be no obligation of the Beneficiaries to give notice to, or obtain
the consent of, the Depositor with respect to the happening or any of the
foregoing.

          SECTION 1.6.  Enforcement.  A Beneficiary may enforce this Agreement
directly against the Depositor and the Depositor waives any right or remedy to
require that any action be brought against the Issuer Trust or any other person
or entity before proceeding against the Depositor.

          SECTION 1.7.  Subrogation.  The Depositor shall be subrogated to all
rights (if any) of any Beneficiary against the Issuer Trust in respect of any
amounts paid to the Beneficiaries by the Depositor under this Agreement;
provided, however, that the Depositor shall not (except to the extent required
by mandatory provisions of law) be entitled to enforce or exercise any rights
that it may acquire by way of subrogation or any indemnity, reimbursement or
other agreement, in all cases as a result of payment under this Agreement, if,
at the time of any such payment, any amounts are due and unpaid under this
Agreement or any payments are due to the holders of Capital Securities under the
Trust Agreement.


                                   ARTICLE II

          SECTION 2.1.  Assignment.  This Agreement may not be assigned by
either party hereto without the consent of the other, and any purported
assignment without such consent shall be void; except that upon any transfer of
the Common Securities, this Agreement shall be assigned and delegated by the
Depositor to its successor with such transfer without any action by either party
hereto.

          SECTION 2.2.  Binding Effect.  All guarantees and agreements contained
in this Agreement shall bind the successors, assigns, receivers, trustees and
representatives of the Depositor and shall inure to the benefit of the
Beneficiaries.

          SECTION 2.3.  Amendment.  So long as there remains any Beneficiary or
any Capital Securities are outstanding, this Agreement shall not be modified or
amended in any manner adverse to such Beneficiary or to

                                      E-2

the holders of the Capital Securities without the consent of such Beneficiary or
the holders of the Capital Securities, as the case may be.

          SECTION 2.4.  Notices.  Any notice, request or other communication
required or permitted to be given hereunder shall be given in writing by
delivering the same against receipt therefor by facsimile transmission

          and obligations as are specifically set forth in this Guarantee

               (B) in the absence of bad faith on the part of the Guarantee
          Trustee, the Guarantee Trustee may conclusively rely, as to the truth
          of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the Guarantee
          Trustee and conforming to the requirements of this Guarantee
          Agreement; but in the case of any such certificates or opinions that
          by any provision hereof or of the Trust Indenture Act are specifically
          required to be furnished to the Guarantee Trustee, the Guarantee
          Trustee shall be under a duty to examine the same to determine whether
          or not they conform to the requirements of this Guarantee Agreement;

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

          (iii)  The Guarantee Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with
     the direction of the Holders of not less than a Majority in Liquidation
     Amount of the Capital Securities relating to the time, method and place of
     conducting any proceeding for any remedy available to the Guarantee
     Trustee, or exercising any trust or power conferred upon the Guarantee
     Trustee under this Guarantee Agreement; and

          (iv) No provision of this Guarantee Agreement shall require the
     Guarantee Trustee to expend or risk its own funds or otherwise incur
     personal financial liability in the performance of any of its duties or in
     the exercise of any of its rights or powers if the Guarantee Trustee shall
     have reasonable grounds for believing that the repayment of such funds or
     liability is not assured to it under the terms of this Guarantee Agreement
     or adequate indemnity against such risk or liability is not reasonably
     assured to it.
