                          NORTHERN TRUST CORPORATION 

  Northern Trust Corporation (Corporation) is a bank holding company within the
meaning of the Bank Holding Company Act of 1956, as amended. The Corporation was
organized in Delaware in 1971 and that year became the owner of all of the
outstanding capital stock, except directors' qualifying shares of The Northern
Trust Company (Bank), an Illinois banking corporation headquartered in the
Chicago financial district and the Corporation's principal subsidiary. The
Corporation also owns banking subsidiaries in Arizona, California, Florida and
Texas, trust companies in Connecticut and New York and various other nonbank
subsidiaries, including a securities brokerage firm, a retirement services
company and a futures commission merchant. The Corporation expects that although
the operations of other subsidiaries will be of increasing significance, the
Bank will in the foreseeable future continue to be the major source of the
Corporation's assets, revenues and net income. Except where the context
otherwise requires, the term "Northern Trust" refers to Northern Trust
Corporation and its consolidated subsidiaries.

  At December 31, 1996, Northern Trust had consolidated total assets of
approximately $21.6 billion and stockholders' equity of approximately $1.5
billion. At September 30, 1996 Northern Trust was the second largest bank
holding company headquartered in Illinois and the 34th largest in the United
States, based on consolidated total assets of approximately $21.4 billion on
that date.

                          THE NORTHERN TRUST COMPANY

  The Bank was founded by Byron L. Smith in 1889 to provide banking and trust
services to the public. Currently in its 108th year, the Bank's growth has come
primarily from internal sources rather than through merger or acquisition. At
December 31, 1996, the Bank had consolidated assets of approximately $18.1
billion. At September 30, 1996, the Bank was the third largest bank in Illinois
and the 33rd largest in the United States, based on consolidated total assets of
approximately $18.2 billion on that date.

  The Bank currently has sixteen banking offices in the Chicago metropolitan
area and nine active wholly owned subsidiaries: The Northern Trust International
Banking Corporation, NorLease, Inc., MFC Company, Inc., Nortrust Nominees Ltd.,
The Northern Trust Company U.K. Pension Plan Limited, The Northern Trust
Company, Canada, Northern Global Financial Services Limited, Northern Trust
Trade Services Limited and Northern Trust Fund Managers (Ireland) Ltd. The
Northern Trust International Banking Corporation, located in New York, was
organized under the Edge Act for the purpose of conducting international
business. NorLease, Inc. was established by the Bank to enable it to broaden its
leasing and leasing-related lending activities. MFC Company, Inc. holds
properties that are received from the Bank in connection with certain problem
loans. Nortrust Nominees Ltd., located in London, is a U.K. trust corporation
organized to hold U.K. real estate for fiduciary accounts. The Northern Trust
Company U.K. Pension Plan Limited, located in London, was established in
connection with the pension plan for the Bank's London Branch. The Northern
Trust Company, Canada, located in Toronto, was established to offer
institutional trust products and services to Canadian entities. Northern Global
Financial Services Ltd., located in Hong Kong, provides securities lending and
relationship services for large asset custody clients in Asia and the Pacific
Rim. Northern Trust Trade Services Limited provides trade finance services, and
Northern Trust Fund Managers (Ireland) Ltd. provides fund management services to
offshore clients.

                 OTHER NORTHERN TRUST CORPORATION SUBSIDIARIES

  The Corporation's Florida banking subsidiary, Northern Trust Bank of Florida
N.A., headquartered in Miami, at December 31, 1996 had twenty-two offices
located throughout Florida, with total assets of approximately $2.3 billion. The
Corporation's Arizona banking subsidiary, Northern Trust Bank of Arizona N.A.,
is headquartered in Phoenix and at December 31, 1996 had total assets of
approximately $401 million and served clients from six office locations in
Arizona. The Corporation's Texas banking subsidiaries, Northern Trust Bank of
Texas N.A., headquartered in Dallas, and Bent Tree National Bank, also
headquartered in Dallas, had seven office locations and total assets of
approximately $604 million at December 31, 1996. The Corporation's California
banking subsidiary, Northern Trust Bank of California N.A., is headquartered in
Santa Barbara. At December 31, 1996, it had six office locations and total
assets of approximately $437 million.

  The Corporation has several nonbank subsidiaries. Among them are Northern
Trust Securities, Inc. which provides full brokerage services to clients of the
Bank and the Corporation's other banking and trust subsidiaries and selectively
underwrites general obligation tax-exempt securities. Northern Futures
Corporation is a futures commission merchant. Northern Investment Corporation
holds certain investments, including a loan made to a developer of a property in
which the Bank is the principal tenant. Berry, Hartell, Evers & Osborne, Inc. is

securities held by trust, agency, and fiduciary accounts administered by the
Corporation's subsidiaries. Northern Trust Cayman International, Ltd. provides

                             INTERNAL ORGANIZATION

  Northern Trust, under Chairman and Chief Executive Officer William A. Osborn,
organizes client services into two principal business units: Corporate and
Institutional Services and Personal Financial Services. In addition, the
Worldwide Operations and Technology business unit encompasses all trust and
banking operations and systems activities. These three business units, and the
Investment Services Group report to President and Chief Operating Officer Barry
G. Hastings. Also, a Risk Management unit focuses on financial and risk
management.

  The following is a brief summary of each unit's business activities.

Corporate and Institutional Services 

  Corporate and Institutional Services (C&IS), headed by Sheila A. Penrose,
Executive Vice President of the Corporation and of the Bank, provides trust,
commercial banking and treasury management services to corporate and
institutional clients.

  Trust activities encompass custody services for owners of securities in the
United States and foreign markets, as well as securities lending, asset
management and related cash management services. Master Trust and Master Custody
are the principal products. Services with respect to securities traded in
foreign markets are provided primarily through the Bank's London Branch. Related
foreign exchange services are also rendered at the London Branch as well as in
Chicago and in Singapore.

  As measured by assets administered and by number of clients, Northern Trust is
a leading provider of Master Trust and Master Custody services in various market
segments. At December 31, 1996, total assets under administration were $693.7
billion. The major market segments served are large U.S. corporate,
institutional (insurance companies, foundations and endowments, and
correspondent trust services) and international clients, and public and union
retirement funds. The Northern Trust Company of New York, The Northern Trust
Company, Canada, NorLease, Inc., The Northern Trust International Banking
Corporation, Northern Futures Corporation, Northern Trust Retirement Consulting,
Inc., and Northern Trust Global Advisors, Inc. are also included in C&IS.

  A full range of commercial banking services is offered through the Bank, which
places special emphasis on developing institutional relationships in two target
markets: large domestic corporations and financial institutions (both domestic
and international). Credit services are administered in two groups: a Large
Corporate Group and a Financial Institutions Group.

  Treasury management services are provided to corporations and financial
institutions and include lockbox collection, controlled disbursement products
and electronic banking, and other products and services to accelerate cash
collections, control disbursement outflows, and generate information to manage
cash positions.

Personal Financial Services

  Services to individuals is another major dimension of the trust business.
Headed by Mark Stevens, Executive Vice President of the Corporation and of the
Bank, Personal Financial Services (PFS) encompasses personal trust, estate
administration, personal banking, mortgage lending and trust and banking
services to individuals and middle market companies. A key element of the
personal trust business is to provide private banking and trust services to
targeted high net worth individuals in rapidly growing areas of wealth
concentration.

  PFS services are delivered through the Bank and a network of banking
subsidiaries located in Arizona, California, Florida and Texas. PFS is one of
the largest bank managers of personal trust assets in the United States, with
total assets under administration of $85.2 billion at December 31, 1996.

  Northern Trust Securities, Inc. and Berry, Hartell, Evers & Osborne, Inc. are 
also part of PFS.

Worldwide Operations and Technology

  Supporting all of Northern Trust's business activities is the Worldwide
Operations and Technology Unit. Headed by James J. Mitchell, Executive Vice
President of the Corporation and of the Bank, this unit focuses on supporting
sales, relationship management, transaction processing and product management
activities for  C&IS and PFS.

<PAGE>
- --------------------------------------------------------------------------------
Investment Services

  The Investment Services Group, headed by Executive Vice President James M.
Snyder, provides equity and fixed income research and portfolio management
services to clients of C&IS and PFS. The Group also acts as the investment
adviser to the Corporation's two families of mutual funds, the Northern Funds
and The Benchmark Funds.

Risk Management

  The Risk Management Unit, headed by Senior Executive Vice President and Chief
Financial Officer Perry R. Pero, includes the Credit Policy and Treasury
functions. The Credit Policy function is described fully on page 16 of this
report. The Treasury Department is responsible for managing the Bank's wholesale
funding and interest rate risk, as well as the portfolio of interest rate risk
management instruments under the direction of the Corporate Asset and Liability
Policy Committee. It is also responsible for the investment portfolios of the
Corporation and the Bank and provides investment advice and management services
to the subsidiary banks.

  The Risk Management Unit also includes Corporate Controller, Corporate
Treasurer, Investor Relations and Economic Research functions.

                              GOVERNMENT POLICIES

  The earnings of Northern Trust are affected by numerous external influences,
principally general economic conditions, both domestic and international, and
actions that the United States and foreign governments and their central banks
take in managing their economies. These general conditions affect all of the
Northern Trust's businesses, as well as the quality and volume of their loan and
investment portfolios.

  The Board of Governors of the Federal Reserve System is an important regulator
of domestic economic conditions and has the general objective of promoting
orderly economic growth in the United States. Implementation of this objective
is accomplished by its open market operations in United States Government
securities, its setting of the discount rate at which member banks may borrow
from Federal Reserve Banks and its changes in the reserve requirements for
deposits. The policies adopted by the Federal Reserve Board may strongly
influence interest rates and hence what banks earn on their loans and
investments and what they pay on their savings and time deposits and other
purchased funds. Fiscal policies in the United States and abroad also affect the
composition and use of Northern Trust's resources.

                                  COMPETITION

  Northern Trust's principal business strategy is to provide quality financial
services to targeted market segments in which it believes it has a competitive
advantage and favorable growth prospects. As part of this strategy, Northern
Trust seeks to deliver a level of service to its clients that distinguishes it
from its competitors. In addition, Northern Trust emphasizes the development and
growth of recurring sources of fee-based income and is one of only five major
bank holding companies in the United States that generates more revenues from
fee-based services than from net interest income. Northern Trust seeks to
develop and expand its recurring fee-based revenue by identifying selected
market niches and providing a high level of individualized service to its
clients in such markets. Northern Trust also seeks to preserve its asset quality
through established credit review procedures and by maintaining a conservative
balance sheet. Finally, Northern Trust seeks to maintain a strong management
team with senior officers having broad experience and long tenure.

  Active competition exists in all principal areas in which the subsidiaries are
presently engaged. C&IS and PFS compete with domestic and foreign financial
institutions, trust companies, financial companies, personal loan companies,
mutual funds and investment advisers. Northern Trust is a leading provider of
Master Trust and Master Custody services and has the leading market share in the
Chicago area personal trust market.

  Commercial banking and treasury management services compete with domestic and
foreign financial institutions, finance companies and leasing companies. These
products also face increased competition due to the general trend among
corporations and other institutions to rely more upon direct access to the
credit and capital markets (such as through the direct issuance of commercial
paper) and less upon commercial banks and other traditional financial
intermediaries.

  The chief local competitors of the Bank for trust and banking business are
Bank of America Illinois N.A., First National Bank of Chicago and its affiliate
American National Bank and Trust Company of Chicago, Harris Trust and Savings
Bank, and LaSalle National Bank. Competitive pressures within the custody market
have resulted in consolidation in the industry, and the chief national
competitors of the Bank for Master Trust/Master Custody services are now Mellon
Bank Corporation, State Street Boston Corporation, Bankers Trust New York
Corporation, Chase Manhattan Corporation and Bank of New York Company, Inc.

                          REGULATION AND SUPERVISION

  The Corporation is a bank holding company subject to the Bank Holding Company
Act of 1956, as amended (Act), and to regulation by the Board of Governors of
the Federal Reserve System. The Act limits the activities which may be engaged
in by the Corporation and its nonbanking subsidiaries to those so closely
related to banking or managing or controlling banks as to be a proper incident
thereto. Also, under section 106 of the 1970 amendments to the Act and subject
to certain exceptions, subsidiary banks are prohibited from engaging in certain
tie-in arrangements with non-banking affiliates in connection with any extension
of credit or provision of any property or services.

  The Act also prohibits bank holding companies from acquiring substantially all
the assets of or owning more than 5% of the voting shares of any bank or
nonbanking company which is not already majority owned without prior approval of
the Board of Governors. The Riegle-Neal Interstate Banking and Branching
Efficiency Act of 1994 (Interstate Act) permits an adequately capitalized and
adequately managed bank holding company to acquire, with Federal Reserve Board
approval, a bank located in a state other than the bank holding company's home
state, without regard to whether the transaction is permitted under any state
law, except that a host state may establish by statute the minimum age of its
banks (up to a maximum of 5 years) subject to acquisition by out-of-state bank
holding companies. The Federal Reserve Board may not approve the acquisition if
the applicant bank holding company, upon consummation, would control more than
10% of total U.S. insured depository institution deposits or more than 30% of
the host state's total insured depository institution deposits. The Interstate
Act also permits a bank, with the approval of the appropriate Federal bank
regulatory agency, to establish a de novo branch in a state, other than the
bank's home state, in which the bank does not presently maintain a branch if the
host state has enacted a law that applies equally to all banks and expressly
permits all out-of-state banks to branch de novo into the host state. Commencing
June 1, 1997, banks having different home states may, with approval of the
appropriate Federal bank regulatory agency, merge across state lines, unless the
home state of a participating bank has opted-out. In addition, the Interstate
Act permits any bank subsidiary of a bank holding company to receive deposits,
renew time deposits, close loans, service loans and receive payments on loans
and other obligations as agent for a bank or thrift affiliate, whether such
affiliate is located in a different state or in the same state.

  State laws governing the Corporation's banking subsidiaries allow each bank 
to establish branches anywhere in its state.

  Under the Federal Deposit Insurance Act (FDIA), an insured depository
institution which is commonly controlled with another insured depository
institution shall generally be liable for any loss incurred, or reasonably
anticipated to be incurred, by the Federal Deposit Insurance Corporation (FDIC)
in connection with the default of such commonly controlled institution, or for
any assistance provided by the FDIC to such commonly controlled institution,
which is in danger of default. The term "default" is defined to mean the
appointment of a conservator or receiver for such institution. Thus, any of the
Corporation's banking subsidiaries could incur liability to the FDIC pursuant to
this statutory provision in the event of a loss suffered by the FDIC in
connection with any of the Corporation's other banking subsidiaries (whether due
to a default or the provision of FDIC assistance). Such liability is
subordinated in right of payment to deposit liabilities, secured obligations,
any other general or senior liability and any obligation subordinated to
depositors and or other general creditors, other than obligations owed to any
affiliate of the depository institution (with certain exceptions) and any
obligations to shareholders in such capacity. Although neither the Corporation
nor any of its nonbanking subsidiaries may be assessed for such loss under the
FDIA, the Corporation has agreed to indemnify each of its banking subsidiaries,
other than the Bank, for any payments a banking subsidiary may be liable to pay
to the FDIC pursuant to these provisions of the FDIA.

  The Bank is a member of the Federal Reserve System, its deposits are insured
by the FDIC and it is subject to regulation by both these entities, as well as
by the Illinois Office of Banks and Real Estate. The Bank is also a member of
and subject to the rules of the Chicago Clearinghouse Association, and is
registered as a government securities dealer in accordance with the Government
Securities Act of 1986. As a government securities dealer its activities are
subject to the rules and regulations of the Department of the Treasury. The Bank
is registered as a transfer agent with the Federal Reserve and is therefore
subject to the rules and regulations of the Federal Reserve in this area.

  The national bank subsidiaries are members of the Federal Reserve System and
the FDIC and are subject to regulation by the Comptroller of the Currency.

  The Corporation's nonbanking affiliates are all subject to examination by the
Federal Reserve. In addition, The Northern Trust Company of New York is subject
to regulation by the Banking Department of the State of New York. Northern
Futures Corporation, which is registered as a futures commission merchant with
the Commodity Futures Trading Commission, is a member of the National Futures
Association, the Chicago Board of Trade and the Board of Trade Clearing
Corporation, and a clearing member of the Chicago Mercantile Exchange. Northern
Trust Securities, Inc. is registered with the Securities and Exchange Commission
and is a member of the National Association of Securities Dealers, Inc., and, as
such, is subject to the rules and regulations of both these bodies. Berry,
Hartell, Evers & Osborne, Inc. and Northern Trust

Retirement Consulting, Inc. are both registered with the Securities and
Exchange Commission under the Investment Advisers Act of 1940 and are subject to
that Act and the rules and regulations of the Commission promulgated thereunder.
Northern Trust Retirement Consulting, Inc. is also registered as a transfer
agent with the Securities and Exchange Commission under the Securities Exchange
Act of 1934 and is subject to that Act and the rules and regulations of the
Commission promulgated thereunder. Northern Trust Global Advisors, Inc. is
subject to regulation by the Securities and Exchange Commission and the Illinois
Securities Department. Its subsidiary RCB Trust Company is subject to regulation
by the Connecticut Department of Banking. Two families of mutual funds for which
the Bank acts as investment adviser are also subject to regulation by the
Securities and Exchange Commission under the Investment Company Act. The Bank
also acts as investment adviser of an investment company which is subject to
regulation by the Central Bank of Ireland under the Companies Act, 1990. Various
other subsidiaries and branches conduct business in other states and foreign
countries and are subject to their regulations and restrictions.

  The Corporation and its subsidiaries are affiliates within the meaning of the
Federal Reserve Act so that the banking subsidiaries are subject to certain
restrictions with respect to loans to the Corporation or its nonbanking
subsidiaries and certain other transactions with them or involving their
securities. Information regarding these restrictions, and dividend restrictions
on banking subsidiaries, is incorporated herein by reference to Note 14 titled
"Restrictions on Subsidiary Dividends and Loans or Advances" on page 49 of the
Corporation's Annual Report to Stockholders for the year ended December 31,
1996.

  Under the FDIC's risk-based insurance assessment system, each insured bank is
placed in one of nine risk categories based on its level of capital and other
relevant information. Each insured bank's insurance assessment rate is then
determined by the risk category in which it has been classified by the FDIC.
There is currently a twenty-seven basis point spread between the highest and
lowest assessment rates, so that banks classified as strongest by the FDIC are
subject in 1997 to .013% assessment, and banks classified as weakest by the FDIC
are subject to an assessment rate of .283%.

  The Federal bank regulators have adopted risk-based capital guidelines for
bank holding companies and banks. The minimum ratio of qualifying total capital
to risk-weighted assets (including certain off-balance sheet items) (Total
Capital Ratio) is 8%. At least half of the Total Capital is to be comprised of
common stock, retained earnings, noncumulative perpetual preferred stock,
minority interests and, for bank holding companies, a limited amount of
qualifying cumulative perpetual preferred stock, less certain intangibles
including goodwill (Tier 1 capital). The balance may consist of other preferred
stock, certain other instruments, and limited amounts of subordinated debt and
the loan and lease loss allowance.

  In addition, the Federal Reserve has established minimum Leverage Ratio (Tier
1 capital to quarterly average total assets) guidelines for bank holding
companies and banks. The Federal Reserve's guidelines provide for a minimum
Leverage Ratio of 3% for bank holding companies and banks that meet certain
specified criteria, including having the highest regulatory rating. All other
banking organizations are required to maintain a Leverage Ratio of at least 3%
plus an additional cushion of 100 to 200 basis points. The guidelines also
provide that banking organizations experiencing internal growth or making
acquisitions will be expected to maintain strong capital positions substantially
above the minimum supervisory levels, without significant reliance on intangible
assets. Furthermore, the guidelines indicate that the Federal Reserve will
continue to consider a "Tangible Tier 1 Leverage Ratio" in evaluating proposals
for expansion or new activities. The Tangible Tier 1 Leverage Ratio is the ratio
of Tier 1 capital, less intangibles not deducted from Tier 1 capital, to
quarterly average total assets. As of December 31, 1996, the Federal Reserve had
not advised the Corporation of any specific minimum Leverage Ratio applicable to
it.

  Federal bank regulators continue to indicate their desire to raise capital
requirements applicable to banking organizations. The Federal Reserve has
recently added interest rate and market risk components to risk-based capital
requirements.

  In addition to the effects of the provisions described above, the Federal
Deposit Insurance Corporation Improvement Act of 1991 (FDICIA) substantially
revised the depository institution regulatory and funding provisions of the FDIA
and made revisions to several other federal banking statutes.

  Among other things, FDICIA requires the federal banking regulators to take
prompt corrective action in respect of FDIC-insured depository institutions that
do not meet minimum capital requirements. FDICIA establishes five capital tiers:
"well capitalized," "adequately capitalized," "undercapitalized," "significantly
undercapitalized" and "critically undercapitalized." A depository institution's
capital tier will depend upon how its capital levels compare to various relevant
capital measures and certain other factors, as established by regulation. Under
applicable regulations, an FDIC-insured bank is defined to be well capitalized
if it maintains a Leverage Ratio of at least 5%, a Tier 1 Capital Ratio (Tier 1
capital to risk-weighted assets) of at least 6% and a Total Capital Ratio of at
least 10% and is not otherwise in a "troubled condition" as specified by its
appropriate federal regulatory agency. A bank is generally considered to be
adequately capitalized if it is not defined to be well capitalized but meets all
of its minimum capital requirements, i.e., if it has a Total Capital Ratio of 8%
or greater, a Tier 1 capital ratio of 4% or greater and a Leverage Ratio of 4%
or greater (or a Leverage Ratio of 3% or greater if

the institution is rated composite 1 in its most recent report of examination,
subject to appropriate federal banking agency guidelines). A bank will be
considered undercapitalized if it fails to meet any minimum required measure,
significantly undercapitalized if it is significantly below such measure and
critically undercapitalized if it maintains a level of tangible equity capital
equal to or less than 2% of total assets. A bank may be deemed to be in a
capitalization category that is lower than is indicated by its actual capital
position if it receives an unsatisfactory examination rating.

  FDICIA generally prohibits an FDIC-insured depository institution from making
any capital distribution (including payment of dividends) or paying any
management fee to its holding company if the depository institution would
thereafter be undercapitalized. Undercapitalized depository institutions are
subject to growth limitations and are required to submit a capital restoration
plan. The federal banking agencies may not accept a capital plan without
determining, among other things, that the plan is based on realistic assumptions
and is likely to succeed in restoring the depository institution's capital. In
addition, for an undercapitalized depository institution's capital restoration
plan to be acceptable, its holding company must guarantee the capital plan up to
an amount equal to the lesser of 5% of the depository institution's assets at
the time it became undercapitalized or the amount of the capital deficiency when
the institution fails to comply with the plan. In the event of the parent
holding company's bankruptcy, such guarantee would take priority over the
parent's general unsecured creditors. If a depository institution fails to
submit an acceptable plan, it is treated as if it is significantly
undercapitalized.

  Significantly undercapitalized depository institutions may be subject to a
number of requirements and restrictions, including orders to sell sufficient
voting stock to become adequately capitalized, requirements to reduce total
assets and cessation of receipt of deposits from correspondent banks. Critically
undercapitalized depository institutions are subject to appointment of a
receiver or conservator.

  At December 31, 1996, the Bank and each of the Corporation's other subsidiary
banks met or exceeded the minimum regulatory ratios that are one of the
conditions for them to be considered to be well capitalized. At December 31,
1996, the Bank had Leverage, Total Capital and Tier 1 Capital Ratios of 6.1%,
10.8% and 7.8%, respectively.

  FDICIA also contains a variety of other provisions that affect the operations
of a bank, including reporting requirements, regulatory standards for real
estate lending, "truth in savings" provisions and a requirement that a
depository institution give 90 days' prior notice to customers and regulatory
authorities before closing any branch.

  Northern Trust employed 6,933 full-time equivalent officers and staff members
as of December 31, 1996, approximately 5,053 of whom were employed by the Bank.

                            CREDIT RISK MANAGEMENT 

Overview 

     The Credit Policy function reports to the Corporation's Chief Financial
Officer. Credit Policy provides a system of checks and balances for Northern
Trust's diverse credit-related activities by establishing and monitoring all
credit-related policies and practices and ensuring their uniform application.
These activities are designed to ensure that credit exposure is diversified on
an industry and client basis, thus lessening the overall credit risk.

     Individual credit authority for commercial loans and within Personal
Financial Services is limited to specified amounts and maturities. Credit
decisions involving commitment exposure in excess of the specified individual
limits are submitted to the appropriate Credit Approval Committee (Committee).
Each Committee is chaired by the executive in charge of the area and has a
Credit Policy officer as a voting participant. Each Committee's credit approval
authority is specified, based on commitment levels, credit ratings and
maturities. Credits involving commitment exposure in excess of these group
credit limits require, dependent upon the internal credit rating, the approval
of the Senior Credit Committee, the head of Credit Policy or the business unit
head.

     Credit Policy established the Counterparty Risk Management Committee in
order to manage counterparty risk more effectively. This committee has sole
credit authority for exposure to all foreign banks, certain domestic banks which
Credit Policy deems to be counterparties and which do not have commercial credit
relationships within the Corporation, and other organizations which Credit
Policy deems to be counterparties.

     Under the auspices of Credit Policy, country exposure limits are reviewed
and approved on a country-by-country basis.

     As part of the Northern Trust's ongoing credit granting process, internal
credit ratings are assigned to each client and credit before credit is extended,
based on creditworthiness. Credit Policy performs at least annually a review of
selected significant credit exposures to identify at the earliest possible
stages clients who might be facing financial difficulties. Internal credit
ratings are also reviewed during this process. Above average risk loans, which
will vary from time to time, receive special attention by both lending officers
and Credit Policy. This approach allows management to take remedial action in an
effort to deal with potential problems.

     An integral part of the Credit Policy function is a monthly formal review
of all past due and potential problem loans to determine which credits, if any,
need to be placed on nonaccrual status or charged off. The provision is reviewed
quarterly to determine the amount necessary to maintain an adequate reserve for
credit losses.

     Management of credit risk is reviewed by various bank regulatory agencies.
Independent auditors also perform a review of credit-related procedures, the
loan portfolio and other extensions of credit, and the reserve for credit losses
as part of their examination of the consolidated financial statements.

Allocation of the Reserve for Credit Losses 

     The reserve for credit losses is established and maintained on an overall
basis and in practice is not specifically allocated to specific loans or
segments of the portfolio. Thus, the reserve is available to absorb credit
losses from all loans and leases. Bank disclosure guidelines issued by the
Securities and Exchange Commission request management to furnish a breakdown of
the reserve for credit losses by loan category and provide the percentage of
loans in each category to total loans.

     Prior to 1994, the allocation of the reserve represented an estimate of the
amount that was necessary to provide for potential losses related to specific
nonperforming loans only. Beginning in 1994, the methodology was revised to
allocate the reserve for credit losses associated with all loans, leases and
commitments based on historical loss experience, internal credit ratings and
specific amounts designated for certain above average risk loans. Other factors
taken into consideration are changes in economic or business conditions, changes
in the nature or volume of the loan portfolio including trends in and the
severity of past due and classified loans. This allocation method should not be
interpreted as an indication of expected losses within the next year or any
specified time period.

     At December 31, 1993, $.2 million of the reserve was allocated based on an
estimate of the amount that was necessary to provide for potential losses
related to specific nonperforming loans only, while $145.3 million remained
unallocated of the total $145.5 million reserve balance. At December 31, 1992,
$11.0 million was so allocated, while $134.5 million remained unallocated of the
total $145.5 million reserve balance.

     Shares of Preferred Stock may be issued in one or more series at such time 
or times, and for such consideration or considerations as the Board of Directors
may determine. All shares of any one series of Preferred Stock will be identical
with each other in all respects, except that shares of any one series issued at 
different times may differ as to dates from which dividends thereon may be 
cumulative. All series will rank equally and be identical in all respects, 
except as permitted by the following provisions of paragraph 2 of this Division 
I.

2.   Authority of the Board with respect to Series.

     The Board of Directors is authorized, at any time and from time to time, to
provide for the issuance of shares of Preferred Stock in one or more series with
such designations, preferences and relative, participating, optional or other 
special rights and qualifications, limitations or restrictions thereof as are
stated and expressed in the resolution or resolutions providing for the issue

including, but not limited to, determination of any of the following:

          (a)  the distinctive serial designation and the number of shares 
     constituting a series;

<PAGE>
 
          (b)  the dividend rate or rates, whether dividends are cumulative and,
     if so, from which date, the payment date or dates for dividends, and the
     participating or other special rights, if any, with respect to dividends;

          (c)  the voting powers, full or limited, if any, of the shares of the
     series;

          (d)  whether the shares are redeemable and, if so, the price or prices
     at which, and the terms and conditions on which, the shares may be
     redeemed;

          (e)  the amount or amounts payable upon the shares in the event of
     voluntary or involuntary liquidation, dissolution or winding up of the
     Corporation prior to any payment or distribution of the assets of the
     Corporation to any class or classes of stock of the Corporation ranking
     junior to the Preferred Stock;

          (f)  whether the shares are entitled to the benefit of a sinking or
     retirement fund to be applied to the purchase or redemption of shares of a
     series and, if so entitled, the amount of the fund and the manner of its
     application, including the price or prices at which the shares may be
     redeemed or purchased through the application of the fund;

          (g)  whether the shares are convertible into, or exchangeable for,
     shares of any other class or classes or of any other series of the same or
     any other class or classes of stock of the Corporation and, if so
     convertible or exchangeable, the conversion price or prices, or the rates
     of exchange, and the adjustments thereof, if any, at which the conversion

     participating, optional or other special rights, and qualifications,
     limitations or restrictions of a series, as the Board of Directors may deem
     advisable and as are not inconsistent with the provisions of this Restated
     Certificate of Incorporation.

3.   Dividends.

     Before any dividends on any class or classes of stock of the Corporation 
ranking junior to the Preferred stock (other than dividends payable in shares of
any class or classes of stock of the Corporation ranking junior to the Preferred
Stock) may be declared or paid or set apart for payment, the holders of shares
of Preferred Stock of each series are entitled to such cash dividends, but only
when and as declared by the Board of Directors out of funds legally available
therefor, as they may be entitled to in accordance with the resolution or
resolutions adopted by the Board of Directors providing for the issue of the
series, payable on such dates in each year as may be fixed in the resolution or
resolutions. The term "class or classes of stock of the Corporation ranking
junior to the Preferred Stock" means the Common Stock and any other class or
classes of stock of the Corporation hereafter authorized which rank junior to
the Preferred Stock as to dividends or upon liquidation.

                                      -3-

manner by the Corporation (excluding, until the Corporation elects to retire 
them, shares which are held as treasury shares but including shares redeemed, 
shares purchased and retired and shares which have been converted into shares of
Common Stock) will have the status of authorized and unissued shares of 
Preferred Stock and may be reissued.

5.   Voting Rights.

     Unless and except to the extent otherwise required by law or provided in 
the resolution or resolutions of the Board of Directors creating any series of 
Preferred Stock pursuant to this Division I, the holders of the Preferred Stock 
shall have no voting power with respect to any matter whatsoever. In no event 
shall the Preferred Stock be entitled to more than one vote in respect of each 
share of stock except as may be required by law or by this Restated Certificate 
of Incorporation.

6.   Outstanding or Reserved for Issuance Preferred Stock.

(a) Series A Junior Participating Preferred Stock

          1.   Designation and Amount.

          The shares of such series shall be designated as "Series A Junior 
Participating Preferred Stock" (the "Series A Preferred Stock") and the number 
of shares constituting the Series A Preferred Stock shall be 350,000. Such 
number of shares may be increased or decreased by resolution of the Board; 
provided, that no decrease shall reduce the number of shares of Series A 
Preferred Stock to a number less than the number of shares then outstanding plus
the number of shares reserved for issuance upon the exercise of outstanding 
options, rights or warrants or upon the conversion of any outstanding securities
issued by the Corporation convertible into Series A Preferred Stock.

          2.   Dividends and Distributions.

          (A)  Subject to the rights of the holders of any shares of any series 
of Preferred Stock (or any similar stock) ranking prior and superior to the 
Series A Preferred Stock with respect to dividends, the holders of shares of 
Series A Preferred Stock, in preference to the holders of Common Stock, par 
value $1.66-2/3 per share (the "Common Stock"), of the Corporation, and of any 
other junior stock, shall be entitled to receive, when, as and if declared by 
the Board of Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the first day of March, June, September and 
December in each year (each such date being referred to herein as a "Quarterly 
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date
after the first issuance of a share or fraction of a share of Series A Preferred
Stock, in an amount per share (rounded to the nearest cent) equal to the greater
of (a) $31.00 or (b) subject to the provision for adjustment hereinafter set 
forth, 100 times the aggregate per share amount of all cash dividends, and 100 
times the aggregate per share amount (payable in kind) of all non-cash

                                      -4-
<PAGE>
 
dividends or other distributions, other than a dividend payable in shares of
Common Stock or a subdivision of the outstanding shares of Common Stock (by
reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Preferred Stock. In the event the Corporation
shall at any time declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under clause (b) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (B)  The Corporation shall declare a dividend or distribution on the Series
A Preferred Stock as provided in paragraph (A) of this Section immediately after
it declares a dividend or distribution on the Common Stock (other than a 
dividend payable in shares of Common Stock); provided that, in the event no 
dividend or distribution shall have been declared on the Common Stock during the
period between any Quarterly Dividend Payment Date and the next subsequent 
Quarterly Dividend Payment Date, a dividend of $31.00 per share on the Series A 
Preferred Stock shall nevertheless be payable on such subsequent Quarterly 
Dividend Payment Date.

     (C)  Dividends shall begin to accrue and be cumulative on outstanding 
shares of Series A Preferred Stock from the Quarterly Dividends Payment Date 
next preceding the date of issue of such shares, unless the date of issue of 
such shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Series A Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative from such Quarterly Dividend
Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends
paid on the shares of Series A Preferred Stock in an amount less than the total
amount of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of shares of Series A Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

               3.   Voting Rights.

               The holders of shares of Series A Preferred Stock shall have the 
following voting rights:

               (A)  Subject to the provision for adjustment hereinafter set 
     forth, each share of Series A Preferred Stock shall entitle the holder
     thereof to 100 votes on all matters submitted to a vote of the stockholders
     of the Corporation. In the event the Corporation shall at any time declare
     or pay any dividend on the Common Stock payable in shares of Common Stock,
     or effect a subdivision or combination or consolidation of the outstanding
     shares of Common Stock (by reclassification or otherwise than by payment of
     a dividend in shares of Common Stock) into a greater or lesser number of
     shares of Common Stock, then in each such case the number of votes per
     share to which holders of shares of Series A Preferred Stock were entitled
     immediately prior to such event shall be adjusted by multiplying such
     number by a fraction, the numerator of which is the number of shares of
     Common Stock outstanding immediately after such event and the denominator
     of which is the number of shares of Common Stock that were outstanding
     immediately prior to such event.

               (B)  Except as otherwise provided herein, in any Certificate of 
     Designations creating a series of Preferred Stock or any similar stock, or
     by law, the holders of shares of Series A Preferred Stock and the holders
     of shares of Common Stock and any other capital stock of the Corporation
     having general voting rights shall vote together as one class on all
     matters submitted to a vote of stockholders of the Corporation.

               (C)  Except as set forth herein, or as otherwise provided by law,
     holders of Series A preferred Stock shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

               4.   Certain Restrictions.

               (A)  Whenever quarterly dividends or other dividends or 
     distributions payable on the Series A Preferred Stock as provided in
     Section 2 are in arrears, thereafter and until all accrued and unpaid
     dividends and distributions, whether or not declared, on shares of Series A
     Preferred Stock outstanding shall have been paid in full, the Corporation
     shall not:

                    (i)  declare or pay dividends, or make any other
               distributions, on any shares of stock ranking junior (either as
               to dividends or upon liquidation, dissolution or winding up) to
               the Series A Preferred Stock;

                    (ii) declare or pay dividends, or make any other
               distributions, on any shares of stock ranking on a parity (either
               as to dividends or upon liquidation, dissolution or winding up)
               with the Series A Preferred Stock, except dividends paid ratably
               on the Series A Preferred Stock and all such parity stock on
               which dividends are payable or in arrears in proportion to the
               total amounts to which the holders of all such shares are then
               entitled;

                                      -6-
<PAGE>
 
               (iii)  redeem or purchase or otherwise acquire for consideration
          shares of any stock ranking junior (either as to dividends or upon
          liquidation, dissolution or winding up) to the Series A Preferred
          Stock, provided that the Corporation may at any time redeem, purchase
          or otherwise acquire shares of any such junior stock in exchange for
          shares of any stock of the Corporation ranking junior (either as to
          dividends or upon dissolution, liquidation or winding up) to the
          Series A Preferred Stock; or

               (iv)  redeem or purchase or otherwise acquire for consideration
          any shares of Series A Preferred Stock, or any shares of stock ranking
          on a parity with the Series A Preferred Stock, except in accordance
          with a purchase offer made in writing or by publication (as
          determined by the Board of Directors) to all holders of such shares
          upon such terms as the Board of Directors, after consideration of the 
          respective annual dividend rates and other relative rights and 
          preferences of the respective series and classes, shall determine in
          good faith will result in fair and equitable treatment among the
          respective series or classes.

          (B)  The Corporation shall not permit any subsidiary of the
     Corporation to purchase or otherwise acquire for consideration any shares
     of stock of the Corporation unless the Corporation could, under paragraph
     (A) of this Section 4, purchase or otherwise acquire such shares at such
     time in such manner.

          5.   Reacquired Shares.

          Any shares of Series A Preferred Stock purchased or otherwise acquired
by the Corporation in any manner whatsoever shall be retired and canceled
promptly after the acquisition thereof. All such shares shall upon their
cancellation become authorized but unissued shares of Preferred Stock and may be
reissued as part of a new series of Preferred Stock subject to the conditions
and restrictions on issuance set forth in this Restated Certificate of
Incorporation or in any Certificate of Designations creating a series of
Preferred Stock or any similar stock or as otherwise required by law.

          6.   Liquidation, Dissolution or Winding Up.

          Upon any liquidation, dissolution or winding up of the Corporation, no
distribution shall be made (A) to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Series A Preferred Stock unless, prior thereto, the holders of shares of Series
A Preferred Stock shall have received $25,000 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series A
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (B) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series A Preferred Stock, except distributions made ratably on the Series A
Preferred Stock and all such parity stock in proportion to the total amounts to 
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. In the event the Corporation shall at any time
declare or pay

                                      -7-

<PAGE>
 
any dividend on the Common Stock payable in shares of Common Stock, or effect a 
subdivision or combination or consolidation of the outstanding shares of Common 
Stock (by reclassification or otherwise than by payment of a dividend in shares 
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the aggregate amount to which holders of shares of Series A 
Preferred stock were entitled immediately prior to such event under the proviso 
in clause (A) of the preceding sentence shall be adjusted by multiplying such 
amount by a fraction the numerator of which is the number of shares of Common 
Stock outstanding immediately after such event and the denominator of which is 
the number of shares of Common Stock that were outstanding immediately prior to 
such event.

          7.   Consolidation, Merger, etc.

          In case the Corporation shall enter into any consolidation, merger,
combination or other transaction in which the shares of Common Stock are
exchanged for or changed into other stock or securities, cash and/or any other
property, then in any such case each share of Series A Preferred Stock shall at
the same time be similarly exchanged or changed into an amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount of stock, securities, cash and/or any other property
(payable in kind), as the case may be, into which or for which each share of
Common Stock is changed or exchanged. In the event the Corporation shall at any
time declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the amount set forth in the
preceding sentence with respect to the exchange or change of shares of Series A
Preferred Stock shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

          8.   No Redemption.

          The shares of Series A Preferred Stock shall not be redeemable.

          9.   Rank.

          The Series A Preferred Stock shall rank, with respect to the payment
of dividends and the distribution of assets, junior to all series of any other
class of the Corporation's Preferred Stock, unless the terms of any such series
shall provide otherwise.

          10.  Amendment.

          This Restated Certificate of Incorporation shall not be amended in any
manner which would materially alter or change the powers, preferences or special
rights of the Series A Preferred Stock so as to affect them adversely without
the affirmative vote of the holders of at least two-thirds of the outstanding
shares of Series A Preferred Stock, voting together as a single class.

                                    PART I

          1.   Designation.

          The designation of said series of Preferred Stock shall be Auction 
Preferred Stock, Series C (the "Series C Stock"). The number of shares of Series
C Stock shall be 600. The stated value of the Series C Stock shall be $100,000 
per share.

          2.   Dividends.

          (a) The Holders (as defined in Section 8 of this Part I) shall be 
entitled to receive; when and as declared by the Board of Directors (as defined 
in Section 8 of this Part I) out of funds legally available therefor, cumulative
cash dividends, at the Applicable Rate (as defined in subparagraph (c)(i) of 
this Section 2) per annum, determined as set forth below, and no more, payable 
on the respective dates set forth below.

          (b)(i) Dividends on shares of Series C Stock at the Applicable Rate 
per annum shall accrue from the Date of Original Issue (as defined in Section 8

and on each succeeding seventh Wednesday thereafter, except that if:

                         (A)(l)    the Securities Depository (as defined in 
                 Section 1 of Part II of this paragraph 6(b) of Article Fourth)
                 shall not have advised the Trust Company (as defined in Section
                 8 of this Part I) at least five Business Days prior to such
                 Wednesday that it will make available to its participants and
                 members on Dividend Payment Dates, in funds immediately
                 available in New York City, the amount due as dividends on such
                 Dividend Payment Dates, and (2)(X) such Wednesday is not a
                 Business Day (as defined in Section 8 of this Part I), (Y) the
                 Thursday following such Wednesday is not a Business Day or (Z)
                 both the Tuesday and the Monday preceding such Wednesday are
                 not Business Days, then on the first Business Day that (i) is
                 preceded by a Business Day that is, or falls after, such
                 preceding Monday and (ii) is immediately followed by a Business
                 day; or
     
                         (B)(l)    the Securities Depository shall have advised 
                 the Trust Company at least five Business Days prior to such
                 Wednesday that it will make available to its participants and
                 members on Dividend Payment Dates, in funds immediately
                 available in New York City, the amount due as dividends on such
                 Dividend Payment Dates and (2)(X) such Wednesday is not a
                 Business Day or (Y) both the Tuesday and the Monday preceding
                 such Wednesday are not Business Days, then on the first
                 Business Day after such Wednesday that is preceded by a
                 Business Day that is, or falls after, such preceding Monday;

provided, however, that the Board of Directors, in the event of a change in law 
lengthening the minimum holding period (currently found in Section 246(c) of the
Code (as defined in Section 8 of this Part I)) required for taxpayer's to be
entitled to the dividends received deduction on

                                      -9-
<PAGE>

preferred stock held by nonaffiliated corporations (currently found in Section 
243(a) of the Code), shall adjust the period of time between Dividend Payment 
Dates (as hereinafter defined) so as, subject to clauses (A) and (B) of this 
subparagraph (b)(i), to adjust uniformly the number of days (such number of days
without giving effect to such clauses (A) and (B) being hereinafter referred to
as "Dividend Period Days") in Dividend Periods (as defined in subparagraph
(c)(i) of this Section 2) commencing after the date of such change in law to
exceed the then current minimum holding period, provided that the number of
Dividend Period Days shall not exceed by more than nine days the length of such
then current minimum period and in no event shall exceed 98 days and that
dividends shall continue to be payable, subject to clauses (A) and (B), on
Wednesdays (each date of payment of dividends being herein referred to as a
"Dividend Payment Date" and the first Dividend Payment Date being herein
referred to as the "Initial Dividend Payment Date"). Upon any such change in the
number of Dividend Period Days as a result of a change in law, the Corporation
shall publish notice of such change in a newspaper of general circulation to the
financial community in The City of New York, New York, which carries financial
news and is customarily published on each Business Day and shall mail notice of
such change by first class mail, postage prepaid, to each Holder at such
Holder's address as the same appears on the stock register of the Corporation.

     (ii)  As long as the Applicable Rate is based on the results of an Auction
(as defined in Section 8 of this Part I), the Corporation shall pay to the
Paying Agent (as defined in Section 8 of this Part I) not later than 12:00 noon,
New York City time, on the Business Day next preceding each Dividend Payment
Date, an aggregate amount of funds available on the next Business Day in The
City of New York, New York, equal to the dividends to be paid to all Holders on
such Dividend Payment Date. All such moneys shall be held in trust for the
payment of such dividends by the Paying Agent for the benefit of the Holders
specified in subparagraph (iii) of this paragraph (b).

     (iii) Each dividend shall be payable to the Holders as their names appear 
on the stock register of the Corporation on the Business Day next preceding the 
Dividend Payment Date thereof; provided, however, that if a Rate Adjustment
Event (as defined in Section 8 of this Part I) shall have occurred and shall not
have been cured by paying all dividends accrued and unpaid and unpaid redemption
payments, such dividend shall be paid to such Holders as their names appear on
the stock register of the Corporation on such date, not exceeding 15 days
preceding the payment date thereof, as may be fixed by the Board of Directors.
Dividends in arrears for any past Dividend Period may be declared and paid at
any time, without reference to any regular Dividend Payment Date, to the Holders
as their names appear on the stock register of the Corporation on such date, not
exceeding 15 days preceding the payment date thereof, as may be fixed by the
Board of Directors.

     (c)(i)    The dividend rate of shares of Series C Stock shall be 4.85% per 
annum during the period from and after the Date of Original Issue to and 
including the Initial Dividend Payment Date (the "Initial Dividend Period"). 
Commencing on the Initial Dividend Payment Date, the dividend rate on shares of 
Series C Stock for each subsequent dividend period (hereinafter referred to as a
"Subsequent Dividend Period" and collectively as "Subsequent Dividend Periods"; 
and the Initial Dividend Period or any Subsequent Dividend Period being 
hereinafter referred to as a "Dividend Period" and collectively as "Dividend 
Periods") thereafter, which Subsequent Dividend Periods shall commence on the 
day that is the last day of the preceding Dividend Period and shall end on and 
include the next succeeding Dividend Payment date, shall be equal to the rate 
per

                                     -10-
<PAGE>
 
annum that results from implementation of the Auction Procedures (as defined in
Section 8 of this Part I); provided, however, that if a Rate Adjustment Event
shall have occurred and shall not have been cured by paying all accrued and
unpaid dividends and unpaid redemption payments prior to the first day of such
Subsequent Dividend Period, the dividend rate for such Subsequent Dividend
Period shall be a rate per annum equal to 175% of the 60-day "AA" Composite
Commercial Paper Rate (the rate per annum at which dividends are payable on
shares of Series C Stock for any Dividend Period being herein referred to as the
"Applicable Rate"). Any amount of such dividend or redemption price not paid
when due but paid within three business days after such due date shall incur a
late charge to be paid therewith and calculated for such period of nonpayment at
an annualized rate of 175% of the 60-day "AA" Composite Commercial Paper Rate
applied to the amount of such non-payment.

     (ii)  The amount of dividends per share accrued and payable on shares of
Series C Stock for each Dividend Period shall be computed by multiplying the
Applicable Rate for such Dividend Period by a fraction, the numerator of which
shall be the number of days in such Dividend Period (calculated by counting the
first day thereof but excluding the last day thereof) and the denominator of
which shall be 360 and applying the rate obtained against $100,000; and the
amount of dividends per share accrued for any part of any Dividend Period shall
be computed by multiplying the Applicable Rate for such Dividend Period by a
fraction the numerator of which shall be the number of days in such part of such
Dividend Period (calculated by counting the first day thereof but excluding the
last day thereof) and the denominator of which shall be 360 and applying the
rate obtained against $100,000.

     (iii)  The Applicable Rate for each Subsequent Dividend Period shall be
published not later than the fifth Business Day next succeeding the first day of
such Subsequent Dividend Period in a newspaper of general circulation to the
financial community in The City of New York, New York, which carries financial
news and is customarily published on each Business Day.

     (d)(i)  No full dividends shall be declared or paid or set apart for
payment on Preferred Stock of any series ranking, as to dividends, on a parity
with or junior to the Series C Stock for any period unless full cumulative
dividends have been or contemporaneously are declared and paid or declared and a
sum sufficient for the payment thereof set apart for such payment on the Series
C Stock for all Dividend Periods terminating on or prior to the date of payment
of such full cumulative dividends. When dividends are not paid in full, as
aforesaid, upon the Series C Stock and any other Preferred Stock ranking on a
parity as to dividends with the Series C Stock, all dividends declared upon the
Series C Stock and any other Preferred Stock ranking on a parity as to dividends
with the Series C Stock shall be declared pro rata so that the amount of
dividends declared per share on the Series C Stock and such other Preferred
Stock shall in all cases bear to each other the same ratio that accrued
dividends per share on the Series C Stock and such other Preferred Stock bear to
each other. Holders of Series C Stock shall not be entitled to any dividend,
whether payable in cash, property or stocks, in excess of the full cumulative
dividends, as herein provided, on the Series C Stock. No interest, or sum of
money in lieu of interest, shall be payable in respect of any dividend payments
on the Series C Stock which may be in arrears.

     (ii)  So long as any shares of Series C Stock are outstanding, no dividend
(other than a dividend in Common Stock or in any other stock ranking junior to
Series C stock as to dividends and upon liquidation and other than as provided
in subparagraph (i) of this paragraph (d)) shall be declared or paid or set
aside for payment or other distribution declared or made upon the

                                     -11-
<PAGE>
 
Common Stock or upon any other stock ranking junior to or on a parity with the
Series C Stock as to dividends or upon liquidation, nor shall any Common Stock
or any other stock of the Corporation ranking junior to or on a parity with the
Series C Stock as to dividends or upon liquidation be redeemed, purchased or
otherwise acquired for any consideration (or any moneys paid to or made
available for a sinking fund for the redemption of any such stock) by the
Corporation (except by conversion into or exchange for stock of the Corporation
ranking junior to the Series C Stock as to dividends and upon liquidation)
unless, in each case, the full cumulative dividends on all outstanding shares of
Series C Stock shall have been paid for all past Dividend Periods.

     3.   Voting

     The Series C Stock shall not have any voting powers, either full or
limited, except that:

     (a) Unless the vote or consent of the holders of a greater number of shares
shall then be required by law, the consent of the holders of at least 66-2/3% of
all of the shares of Preferred Stock at the time outstanding, given in person or
by proxy, either in writing or by a vote at a meeting called for the purpose at
which the holders of shares of Preferred Stock shall vote together as a separate
class, shall be necessary for authorizing, effecting or validating the
amendment, alteration or repeal of any of the provisions of this Restated
Certificate of Incorporation or of any certificate amendatory thereof or
supplemental thereto (including any Certificate of Designations or any similar
document relating to any series of Preferred Stock) which would adversely affect
the powers, preferences, rights or privileges of the Preferred Stock; provided,
however, that if any such amendment, alteration or repeal would adversely affect
the powers, preferences, rights or privileges of one or more series of the
Preferred Stock, but shall not so affect the entire class, then only the shares
of the one or more series so affected shall be considered to be a separate class
entitled to vote upon or consent to such amendment, alteration or repeal;

     (b) Unless the vote or consent of the holders of a greater number of shares
shall then be required by law, the consent of the holders of at least 66-2/3% of
all of the Series C Stock and all other series of Preferred Stock ranking on a
parity with the Series C Stock, either as to dividends or upon liquidation, at
the time outstanding, given in person or by proxy, either in writing or by a
vote at a meeting called for the purpose at which the holders of Series C Stock
and such other series of Preferred Stock shall vote together as a single class
without regard to series, shall be necessary for authorizing, effecting or
validating the creation, authorization or issue of any shares of any class of
stock of the Corporation ranking prior to the Series C Stock as to dividends or
upon liquidation, or the reclassification of any authorized stock of the
Corporation into any such prior shares, or the creation, authorization or issue
of any obligation or security convertible into or evidencing the right to
purchase any such prior shares; and

     (c) If at the time of any annual meeting of stockholders for the election
of directors a default in preference dividends on the Preferred Stock shall
exist, the number of directors constituting the Board of Directors shall be
increased by two, and the holders of the Preferred Stock of all series shall
have the right at such meeting, voting together as a single class without regard
to series, to the exclusion of the holders of Common Stock, to elect two
directors of the Corporation to fill such newly created directorships. Such
right shall continue until there are no dividends in arrears upon the Preferred
Stock. Each director elected by the holders of shares of Preferred Stock (herein
called a "Preferred Director") shall continue to serve as such director for the
full term for

                                     -12-
<PAGE>
 
which he shall have been elected, notwithstanding that prior to the end of such 
term a default in preference dividends shall cease to exist. Any Preferred 
Director may be removed by, and shall not be removed except by, the vote of the 
holders of record of the outstanding shares of Preferred Stock, voting together 
as a single class without regard to series, at a meeting of the stockholders, or
of the holders of shares of Preferred Stock, called for that purpose. So long as
a default in preference dividends on the Preferred Stock shall exist, (A) any 
vacancy in the office of a Preferred Director may be filled (except as provided 
in the following clause (B)) by an instrument in writing signed ny the remaining
Preferred Director and filed with the Corporation and (B) in the case of the 
removal of any Preferred Director, the vacancy may be filled by the vote of the
holders of the outstanding shares of Preferred Stock, voting together as a
single class without regard to series, at the same meeting at which such removal
shall be voted. Each director appointed as aforesaid by the remaining Preferred
Director shall be deemed, for all purposes hereof, to be a Preferred Director.
Whenever the term of office of the Preferred Directors shall end and a default
in preference dividends shall no longer exist, the number of directors
constituting the Board of Directors shall be reduced by two. For the purposes
hereof, a "default in preference dividends" on the Preferred Stock shall be
deemed to have occurred whenever the amount of accrued dividends upon any series
of the Preferred Stock shall be equivalent to six full quarter-yearly dividends
(which, with respect to the Series C Stock, shall be deemed to be dividends in
respect of a number of Dividend Periods containing not less than 540 days) or
more, and, having so occurred, such default shall be deemed to exist thereafter
until, but only until, all accrued dividends on all shares of Preferred Stock of
each and every series then outstanding shall have been paid to the end of the
last preceding quarterly dividend period.

     4.   Redemption.

     (a)(i) The Series C Stock may be redeemed, at the option of the 
Corporation, as a whole or from time to time in part, on any Dividend Payment 
Date at a redemption price of $100,000 per share plus an amount equal to accrued
and unpaid dividends thereon (whether or not earned or declared) to the date 
fixed for redemption.

     (ii) If fewer than all of the outstanding shares of Series C Stock are to 
be redeemed pursuant to subparagraph (i) of this paragraph (a), the number of 
shares to be redeemed shall be determined by the Board of Directors, and such 
shares shall be redeemed pro rata from the Holders in proportion to the number 
of such shares held by such Holders (with adjustments to avoid redemption of 
fractional shares).

     (b)  If the Corporation shall redeem shares of Series C Stock pursuant to 
paragraph (a) of this Section 4, notice of such redemption shall be given by 
publication at least once in a newspaper printed in the English language and 
customarily published on each Business Day and, whenever published, of general 
circulation in Chicago, Illinois, such publication to be not less than 15 nor 
more than 45 days prior to the date fixed for such redemption. Notice of such 
redemption shall also be given by mailing the same by first class mail, postage 
prepaid, not less than 15 nor more than 45 days prior to the date fixed for 
redemption thereof, to each Holder of the shares to be redeemed, at such 
Holder's address as the same appears on the stock register of the Corporation. 
Each such notice shall state: (i) the redemption date; (ii) the number of shares
of Series C Stock to be redeemed; (iii) the redemption price plus the amount of 
accrued and unpaid dividends to the redemption date; (iv) the place or places 
where certificates for such shares of Series C Stock are to be surrendered for 
payment of the redemption price; and (v) that dividends on the shares to be

                                      -13-
<PAGE>
 
redeemed will cease to accrue on such redemption date. If fewer than all shares
held by any Holder are to be redeemed, the notice mailed to such Holder shall 
also specify the number of shares to be redeemed from such Holder.

     (c)  Notwithstanding the provisions of paragraph (a) of this Section 4, if 
any dividends on the Series C Stock are in arrears, no shares of Series C Stock 
shall be redeemed unless all outstanding shares of Series C Stock are 
simultaneously redeemed, and the Corporation shall not purchase or otherwise 
acquire any shares of Series C Stock; provided, however, that the foregoing 
shall not prevent the purchase or acquisition of shares of Series C Stock 
pursuant to a purchase or exchange offer made on the same terms to Holders of
all outstanding shares of Series C Stock.

     (d)  If notice of redemption has been published under paragraph (b) of this
Section 4 or the Corporation has irrevocably authorized and directed the 
Redemption Agent to begin promptly and complete such publication of notice, and 
the Corporation has deposited in trust with the Redemption Agent funds necessary
for such redemption, from and after the later of the date of such notice or the 
date such deposit is made the shares of Series C Stock called for redemption 
shall no longer be deemed to be outstanding, and all rights of the Holders 
thereof as stockholders of the Corporation (except the right to receive the 
redemption price plus an amount equal to the accrued and unpaid dividends 
thereon to the date fixed for redemption) shall cease. Upon surrender in 
accordance with said notice of the certificates for any shares so redeemed 
(properly endorsed or assigned for transfer, if the Board of Directors shall so 
require and the notice shall so state), the redemption price set forth above 
plus an amount equal to such accrued and unpaid dividends shall be paid by the 
Redemption Agent to the Holders of the shares of Series C Stock subject to 
redemption as set forth in paragraph (e) of this Section 4. In case fewer than 
all of the shares represented by any such certificate are redeemed, a new 
certificate shall be issued representing the unredeemed shares without cost to 
the Holder thereof.

     (e)  As long as the Applicable Rate is based on the results of an Auction, 
the Corporation shall pay the applicable Redemption Deposit Amount (as defined 
in Section 8 of this Part I) to the Redemption Agent, in funds available on the 
next Business Day in The City of New York, New York, on the Business Day next 
preceding the redemption date for disbursement to Holders as appropriate. All 
such moneys shall be held in trust by the Redemption Agent for the benefit of 
Holders of shares so to be redeemed.

     5.   Liquidation Rights.

     (a)  Upon the dissolution, liquidation or winding up of the Corporation, 
the holders of the Series C Stock shall be entitled to receive out of the assets
of the Corporation, before any payment or distribution shall be made on the
Common Stock or on any other class of stock ranking junior to the Preferred
Stock upon liquidation, the amount of $100,000 per share, plus a sum equal to
all dividends (whether or not earned or declared) on such shares accrued and
unpaid thereon to the date of the final distribution.

     (b)  Neither the sale of all or substantially all the property or business 
of the Corporation, nor the merger or consolidation of the Corporation into or 
with any other corporation or the merger or consolidation of any other 
corporation into or with the Corporation, shall be deemed to be a dissolution, 
liquidation or winding up, voluntary or involuntary, for the purposes of this 
Section 5.

                                     -14-
<PAGE>
 
     (c)  After the payment to the holders of the Series C Stock of the full 
preferential amounts provided for in this Section 5, the holders of Series C 
Stock as such shall have no right or claim to any of the remaining assets of the
Corporation.

     (d)  In the event the assets of the Corporation available for distribution 
to the holders of Series C Stock upon any dissolution, liquidation or winding 
up of the Corporation, whether voluntary or involuntary, shall be insufficient 
to pay in full all amounts to which such holders are entitled pursuant to 
paragraph (a) of this Section 5, no such distribution shall be made on account 
of any shares of any other class or series of Preferred Stock ranking on a 
parity with the Series C Stock upon such dissolution, liquidation or winding up 
unless proportionate distributive amounts shall be paid on account of the Series
C Stock, ratably, in proportion to the full distributable amounts for which 
holders of all such parity shares are respectively entitled upon such 
dissolution, liquidation or winding up.

     (e)  Upon the dissolution, liquidation or winding up of the Corporation, 
the holders of shares of Series C Stock then outstanding shall be entitled to be
paid out of the assets of the Corporation available for distribution to its 
stockholders all amounts to which such holders are entitled pursuant to 
paragraph (a) of this Section 5 before any payment shall be made to the holders 
of any class or series of capital stock of the Corporation ranking junior upon 
liquidation to the Series C Stock.

     6.   Sinking or Retirement Fund.

     The Series C Stock shall not be entitled to the benefit of a sinking or 
retirement fund to be applied to the purchase or redemption of such stock.

     7.   Rank

     For purposes of this paragraph 6(b) of Article Fourth, any stock of any 
class or classes of the Corporation shall be deemed to rank:

     (a)  prior to the Series C Stock, either as to dividends or upon 
liquidation, if the holders of such class or classes shall be entitled to the 
receipt of dividends or of amounts distributable upon dissolution, liquidation 
or winding up of the Corporation, as the case may be, in preference or priority 
to the holders of Series C Stock;

     (b)  on a parity with the Series C Stock, either as to dividends or upon 
liquidation, whether or not the dividend rates, dividend payments dates or 
redemption or liquidation prices per share or sinking fund provisions, if any, 
are different from those of the Series C Stock, if the holders of such stock 
shall be entitled to the receipt of dividends or of amounts distributable upon 
dissolution, liquidation or winding up of the Corporation, as the case may be, 
in proportion to their respective dividend rates or liquidation prices, without 
preference or priority, one over the other, as between the holders of such stock
and the holders of Series C Stock; and

     (c)  junior to the Series C Stock, either as to dividends or upon 
liquidation, if such class shall be Common Stock or if the holders of Series C 
Stock shall be entitled to receipt of dividends or of amounts distributable upon
dissolution, liquidation or winding up of the Corporation, as the case may be,
in preference or priority to the holders of shares of such class or classes.

     3.   Submission of Orders by Broker-Dealers to Trust Company.

     (a)  Each Broker-Dealer shall submit in writing to the Trust Company prior

Broker-Dealer and specifying with respect to each Order:

          (i)   the name of the Bidder placing such Order;

          (ii)  the aggregate number of shares of Series C Stock that are the 
          subject of such Order;

                (A) the number of shares, if any, of Series C Stock subject to 
                any Hold Order placed by such Existing Holder;

                (B) the number of shares, if any, of Series C Stock subject to 
                any Bid placed by such Existing Holder and the rate specified in
                such Bid; and

                (C) the number of shares, if any, of Series C Stock subject to 
                any sell Order placed by such Existing Holder; and

                                     -22-
<PAGE>
 
     (b)    If any rate specified in any Bid contains more than three figures to
the right of the decimal point, the Trust Company shall round such rate up to
the next highest one thousandth (.001) of 1%.

     (c)    If an Order or Orders covering all of the Outstanding shares of
Series C Stock held by any Existing Holder is not submitted to the Trust Company
prior to the Submission Deadline, the Trust Company shall deem a Hold Order
to have been submitted on behalf of such Existing Holder covering the number of
Outstanding shares of Series C Stock held by such Existing Holder and not
subject to Orders submitted to the Trust Company.

     (d)    If one or more Orders covering in the aggregate more than the
number of Outstanding shares of Series C Stock held by any Existing Holder are
submitted to the Trust Company, such Orders shall be considered valid as follows
and in the following order of priority:

          (i)  all Hold Orders shall be considered valid, but only up to and
          including in the aggregate the number of shares of Series C Stock held
          by such Existing Holder, and, solely for purposes of allocating
          compensation among the Broker-Dealers submitting Hold Orders, if the
          number of shares of Series C Stock subject to such Hold Orders exceeds
          the number of shares of Series C Stock held by such Existing Holder,
          the number of shares subject to each Hold Order shall be reduced pro
          rata to cover the number of shares of Series C Stock held by such
          Existing Holder;

          (ii)(A)  any Bid shall be considered valid up to and including the
          excess of the number of Outstanding shares of Series C Stock held by
          such Existing Holder over the number of shares of Series C Stock
          subject to any Hold Order referred to in subparagraph (i) above;

          (B)  subject to clause (A), if more than one Bid with the same rate is
          submitted on behalf of such Existing Holder and the number of shares
          of Series C Stock subject to such Bids is greater than such excess,
          such Bids shall be considered valid up to the amount of such excess,
          and, solely for purposes of allocating compensation among the Broker-
          Dealers submitting Bids with the same rate, the number of shares of
          Series C Stock subject to each Bid with the same rate shall be reduced
          pro rata to cover the number of shares of Series C Stock equal to such
          excess;

          (C)  subject to clause (A), if more than one Bid with different rates
          is submitted on behalf of such Existing Holder, such Bids shall be
          considered valid in the ascending order of their respective rates up
          to the amount of such excess; and

          (D)  in any such event the number, if any, of such shares subject to
          Bids not valid under this subparagraph (ii) shall be treated as the
          subject of a Bid by a Potential Holder; and

     (iii)  all Sell Orders shall be considered valid but only up to and
including in the aggregate the excess of the number of Outstanding shares of
Series C Stock held by such Existing Holder over the sum of the shares of Series
C Stock subject to Hold Orders referred to in subparagraph (i) and valid Bids by
Existing Holders referred to in subparagraph (ii) above.

                                     -23-

<PAGE>
 
     (e)  If more than one Bid is submitted on behalf of any Potential Holder,
each Bid submitted shall be a separate bid with the rate therein specified.

     4.  Determination of Sufficient Clearing Bids, Winning Bid Rate and
         Applicable Rate.

     (a)  Not earlier than the Submission Deadline on each Auction Date, the
Trust Company shall assemble all Orders submitted or deemed submitted to it by
the Broker-Dealers (each such Order as submitted or deemed submitted by a 
Broker-Dealer being hereinafter referred to individually as a "Submitted Hold
Order," a "Submitted Bid" or a "Submitted Sell Order," as the case may be, or as
a "Submitted Order" and collectively as "Submitted Hold Orders," "Submitted
Bids" or "Submitted Sell Orders," as the case may be, or as "Submitted Orders")
and shall determine:

     (i)   the excess of the total number of Outstanding shares of Series C
     Stock over the number of Outstanding shares of Series C Stock that are the
     subject of Submitted Hold Orders (such excess being hereinafter referred to
     as the "Available Series C Stock");

     (ii)  from the Submitted Orders whether:

               (A)  the number of Outstanding shares of Series C Stock that are
               the subject of Submitted Bids by Potential Holders specifying one
               or more rates equal to or lower than the Maximum Rate exceeds or
               is equal to the sum of:

                    (I)  the number of Outstanding shares of Series C Stock that
                    are the subject of Submitted Bids by Existing Holders
                    specifying one or more rates higher than the Maximum Rate,
                    and

                    (II)  the number of Outstanding shares of Series C Stock
                    that are subject to Submitted Sell Orders

               (in the event of such excess or such equality (other than because
               the sum of the number of shares of Series C Stock in clauses (I)
               and (II) above is zero because all of the Outstanding shares of
               Series C Stock are the subject of Submitted Hold Orders), such
               Submitted Bids in clause (A) above being hereinafter referred to
               collectively as "Sufficient Clearing Bids"); and

                    (iii)  if Sufficient Clearing Bids exist, the lowest rate
               specified in the Submitted Bids (the "Winning Bid Rate") which
               if:

                    (A)(I)  each Submitted Bid from Existing Holders specifying
               such lowest rate and (II) all other Submitted Bids from Existing
               Holders specifying lower rates were accepted, thus entitling such
               Existing Holders to continue to hold the shares of Series C Stock
               that are the subject of such Submitted Bids; and

                    (B)(I)  each Submitted Bid from Potential Holders specifying
               such lowest rate and (II) all other Submitted Bids from
               Potential Holders specifying lower rates were accepted, thus
               entitling the Potential Holders to purchase the shares of Series
               C Stock that are the subject of those Submitted Bids,

                                     -24-

<PAGE>
 
would result in such Existing Holders described in clause (A) continuing to hold
an aggregate number of Outstanding shares of Series C Stock which, when added to
the number of Outstanding shares of Series C Stock to be purchased by such
Potential Holders described in clause (B), would equal not less than the
Available Series C Stock.

     (b)  Promptly after the Trust Company has made the determinations pursuant 
to paragraph (a) of this Section 4, the Trust Company shall advise the 
Corporation of the "AA" Composite Commercial Paper Rate and the Maximum Rate 
and, based on such determinations, the Applicable Rate for the next succeeding 
Dividend Period as follows:

               (i) if Sufficient Clearing Bids exist, that the Applicable Rate 
               for the next succeeding Dividend Period shall be equal to the
               Winning Bid Rate so determined;

               (ii) if Sufficient Clearing Bids do not exist (other than because
               all of the Outstanding shares of Series C Stock are the subject
               of Submitted Hold Orders), that the Applicable Rate for the next
               succeeding Dividend Period shall be equal to the Maximum Rate; or

               (iii) if all the Outstanding shares of Series C Stock are the
               subject of Submitted Hold Orders, that the Applicable Rate for
               the next succeeding Dividend Period shall be equal to 59% of the
               "AA" Composite Commercial Paper Rate.

     5.   Acceptance and Rejection of Submitted Bids and Submitted Sell Orders 
and Allocation of Shares.

     Based on the determinations made pursuant to paragraph (a) of Section 4 of
this Part II, the Submitted Bids and Submitted Sell Orders shall be accepted or
rejected and the Trust Company shall take such other action as set forth below:

     (a)  If Sufficient Clearing Bids have been made, subject to the provisions 
of paragraphs (c), (d) and (e) of this Section 5, Submitted Bids and Submitted 
Sell Orders shall be accepted or rejected as follows in the following order of 
priority and all other Submitted Bids shall be rejected:

               (i) the Submitted Sell Orders of Existing Holders shall be 
               accepted and the Submitted Bid of each of the Existing Holders
               specifying any rate that is higher than the Winning Bid Rate
               shall be rejected, thus requiring each such Existing Holder to
               sell the shares of Series C Stock that are the subject of such
               Submitted Bid;

               (ii) the Submitted Bid of each of the Existing Holders specifying
               any rate that is lower than the Winning Bid Rate shall be
               accepted, thus entitling each such Existing Holder to continue to
               hold the shares of Series C Stock that are the subject of each
               Submitted Bid;

               (iii) the Submitted Bid of each of the Potential Holders
               specifying any rate that is lower than the Winning Bid Rate shall
               be accepted;

               (iv) the Submitted Bid of each of the Existing Holders specifying
               a rate that is equal to the Winning Bid Rate shall be accepted,
               thus entitling each such Existing Holder

                                     -25-




        




  
<PAGE>
 
               to continue to hold the shares of Series C Stock that are the
               subject of such Submitted Bid, unless the number of Outstanding
               shares of Series C Stock subject to all such Submitted Bids shall
               be greater than the number of shares of Series C Stock
               ("remaining shares") equal to the excess of the Available Series
               C Stock over the number of shares of Series C Stock subject to 
               Submitted Bids described in subparagraphs (ii) and (iii) of this
               paragraph (a), in which event the Submitted Bids of each such
               Existing Holder shall be rejected, and each such Existing Holder
               shall be required to sell shares of Series C Stock, but only in
               an amount equal to the difference between (A) the number of
               Outstanding shares of Series C Stock then held by such Existing
               Holder subject to such Submitted Bid and (B) the number of shares
               of Series C Stock obtained by multiplying the number of remaining
               shares by a fraction the numerator of which shall be the number
               of Outstanding shares of Series C Stock held by such Existing
               Holder subject to such Submitted Bid and the denominator of which
               shall be the sum of the number of Outstanding shares of Series C
               Stock subject to such Submitted Bids made by all such Existing
               Holders that specified a rate equal to the Winning Bid Rate; and

               (v)  the Submitted Bid of each of the Potential Holders
               specifying a rate that is equal to the Winning Bid Rate shall be
               accepted but only in an amount equal to the number of shares of
               Series C Stock obtained by multiplying the difference between the
               Available Series C Stock and the number of shares of Series C
               Stock subject to Submitted Bids described in subparagraphs (ii),
               (iii) and (iv) of this paragraph (a) by a fraction the numerator
               of which shall be the number of Outstanding shares of Series C
               Stock subject to such Submitted Bid and the denominator of which
               shall be the sum of the number of Outstanding shares of Series C
               Stock subject to such Submitted Bids made by all such Potential
               Holders that specified a rate equal to the Winning Bid Rate.

     (b)  If Sufficient Clearing Bids have not been made (other than because all
of the Outstanding shares of Series C Stock are subject to Submitted Hold 
Orders), subject to the provisions of paragraphs (c), (d) and (e) of this
Section 5, Submitted Orders shall be accepted or rejected as follows in the
following order of priority and all other Submitted Bids shall be rejected:

               (i)    the Submitted Bid of each Existing Holder specifying any 
               rate that is equal to or lower than the Maximum Rate shall be
               accepted, thus entitling such Existing Holder to continue to hold
               the shares of Series C Stock that are the subject of such
               Submitted Bid;

               (ii)   the Submitted Bid of each Potential Holder specifying any
               rate that is equal to or lower than the Maximum Rate shall be
               accepted; and

               (iii)  the Submitted Bids of each Existing Holder specifying any
               rate that is higher than the Maximum Rate shall be rejected and
               the Submitted Sell Orders of each Existing Holder shall be
               accepted, in both cases only in an amount equal to the difference
               between (A) the number of Outstanding shares of Series C Stock
               then held by such Existing Holder subject to such Submitted Bid
               or Submitted Sell Order and (B) the number of shares of Series C
               Stock obtained by multiplying the difference between the
               Available Series C Stock and the aggregate number of shares

                                     -26-
































<PAGE>
 
               of Series C Stock subject to Submitted Bids described in
               subparagraphs (i) and (ii) of this paragraph (b) by a fraction
               the numerator of which shall be the number of Outstanding shares
               of Series C Stock held by such Existing Holder subject to such
               Submitted Bid or Submitted Sell Order and the denominator of
               which shall be the number of Outstanding shares of Series C Stock
               subject to all such Submitted Bids and Submitted Sell Orders.


     (c)  If all of the Outstanding shares of Series C Stock are the subject of 
Submitted Hold Orders, all Submitted Bids shall be rejected.

     (d)  If, as a result of the procedures described in paragraph (a) or (b) of
this Section 5, any Existing Holder would be entitled or required to sell, or
any Potential Holder would be entitled or required to purchase, a fraction of a
share of Series C Stock on any Auction Date, the Trust Company, in such manner
as it shall determine in its sole discretion, shall round up or down the number
of shares of Series C Stock to be purchased or sold by any Existing Holder or
Potential Holder on such Auction Date so that the number of shares purchased or
sold by each Existing Holder or Potential Holder on such Auction Date shall be
whole shares of Series C Stock.

     (e)  If, as a result of the procedures described in paragraph (a) of this 
Section 5, any Potential Holder would be entitled or required to purchase less 
than a whole share of Series C Stock on any Auction Date, the Trust Company, in 
such manner as it shall determine in its sole discretion, shall allocate shares 
for purchase among Potential Holders so that only whole shares of Series C Stock
are purchased on such Auction Date by any Potential Holder, even if such
allocation results in one or more of such Potential Holders not purchasing
shares of Series C Stock on such Auction Date.

     (f) Based on the results of each Auction, the Trust Company shall determine
the aggregate number of shares of Series C Stock to be purchased and the
aggregate number of shares of Series C Stock to be sold by Potential Holders and
Existing Holders on whose behalf each Broker-Dealer submitted Bids or Sell
Orders and, with respect to each Broker-Dealer, to the extent that such
aggregate number of shares to be purchased and such aggregate number of shares
to be sold differ, determine to which other Broker-Dealer or Broker-Dealers
acting for one or more purchasers such Broker-Dealer shall deliver, or from
which other Broker-Dealer or Broker-Dealers acting for one or more sellers such
Broker-Dealer shall receive, as the case may be, shares of Series C Stock.

     6.   Miscellaneous.

     (a) The Board of Directors may interpret the provisions of this Part II to
resolve any inconsistency or ambiguity which may arise or be revealed in
connection with the Auction Procedures provided for herein, and if such
inconsistency or ambiguity reflects an inaccurate provision hereof, the Board of
Directors may, in appropriate circumstances, authorize the filing of a
Certificate of Correction or Certificate of Amendment.

     (b)  So long as the Applicable Rate is based on the results of an Auction, 
an Existing Holder (i) may sell, transfer or otherwise dispose of shares of 
Series C Stock only pursuant to a Bid or Sell Order in accordance with the 
procedures described in this Part II or to or through a Broker-Dealer or to a 
Person that has delivered a signed copy of a Purchaser's Letter to the Trust 
Company, provided that in the case of all transfers other than pursuant to 
Auctions such Existing Holder or

                                     -27-























<PAGE>
 
its Broker-Dealer advises the Trust Company of such transfer, and (ii) shall
have the ownership of the shares of Series C Stock held by it maintained in book
entry form by the Securities Depository in the account of its Agent Member,
which in turn will maintain records of such Existing Holder's beneficial
ownership.

     (c)  Neither the Corporation nor any affiliate thereof may submit an Order
in any Auction. Any Broker-Dealer that is an affiliate of the Corporation may
not submit Bids to purchase shares of Series C Stock in Auctions for its own
account, and if such affiliated Broker-Dealer has otherwise acquired shares for
its own account, it must submit a Sell Order in the next Auction with respect to
such shares.

     (d)  The Trust Company shall reject any Submitted Order of the Corporation 
or an Affiliate, except for Sell Orders of affiliated Broker-Dealers.

     (e)  From and after the occurrence of a Rate Adjustment Event, shares of
Series C Stock shall be registered for transfer or exchange and new certificates
issued upon surrender of the old certificates deemed by the Trust Company (or
any other transfer agent or registrar appointed by the Corporation) properly
endorsed for transfer with all necessary endorsers' signatures guaranteed in
such manner and form as the Trust Company (or such other transfer agent or
registrar) may require by a guarantor reasonably believed by the Trust Company 
(or such other transfer agent or registrar) to be responsible, accompanied by
such assurances as the Trust Company (or such other transfer agent or registrar)
shall deem necessary or appropriate to evidence the genuineness and
effectiveness of each necessary endorsement and satisfactory evidence of
compliance with all applicable laws relating to the collection of taxes or funds
necessary for the payment of such taxes.

BEHALF TO THE RESPECTIVE TRUST COMPANIES.

                           Master Purchaser's Letter
        Relating to Securities Involving Rate Settings through Auctions


To:  The Corporation
     The Trust Company
     A Broker-Dealer
     An Agent Member
     Other Persons

     1.   This letter is designed to apply to auctions for publicly or privately
offered debt or equity securities ("Securities") of any issuer ("Corporation") 
which are described in any final prospectus or other offering materials relating
to such Securities as the same may be amended or supplemented (collectively, 
with respect to the particular Securities concerned, the "Prospectus") and which
involve periodic rate settings through auctions ("Auctions"). This letter shall 
be for the benefit of any Corporation and of any trust company or auction agent 
(collectively, "trust company"), broker-dealer, agent member, securities 
depository or other interested person in connection with any Securities and 
related Auctions (it being understood that such persons may be required to 
execute specified agreements and nothing herein shall alter such requirements). 
The terminology used herein is intended to be general in its application and not
to exclude any Securities in respect of which (in the Prospectus or otherwise) 
alternative terminology is used.

     2.   We may from time to time offer to purchase, purchase, offer to sell

relating thereto. We agree that this letter shall apply to all such purchases, 
sales and offers and to Securities owned by us. We understand that the

results of Auctions as set forth in the Prospectus.

     3.   We agree that any bid or sell order, placed by us shall constitute an 
irrevocable offer by us to purchase or sell the Securities subject to such bid

sell or purchase as a result of such Auction, at the applicable price, all as 
set forth in the Prospectus, and that if we fail to place a bid or sell order 
with respect to Securities owned by us with a broker-dealer on any auction date,
or a broker-dealer to which we communicate a bid or sell order fails to submit 
such bid or sell order to the trust company concerned, we shall be deemed to 
have placed a hold order with respect to such Securities as described in the 
Prospectus. We authorize any broker-dealer that submits a bid or sell order as 
our agent in Auctions to execute contracts for the sale of Securities covered by
such bid or sell order. We recognize that the payment by such broker-dealer for 
Securities purchased on our behalf shall not relieve us of any liability to such
broker-dealer for payment for such Securities.

     4.   We agree that, during the applicable period as described in the 
Prospectus, dispositions of Securities can be made only in the denominations set
forth in the Prospectus and we will sell, transfer or otherwise dispose of any 
Securities held by us from time to time only pursuant to a bid or sell order 
placed in an Auction, to or through a broker-dealer or, when permitted in the 
Prospectus, to a person that has signed and delivered, or caused to be delivered
on its behalf, to the applicable trust company a letter substantially in the 
form of this letter (or

other applicable purchaser's letter), provided that in the case of all transfers
other than pursuant to Auctions we or our broker-dealer or our agent member 
shall advise such trust company of such transfer. We understand that a 
restrictive legend will be placed on certificates representing the Securities 
and stop-transfer instructions will be issued to the transfer agent and/or 
registrar, all as set forth in the Prospectus. We agree to comply with any other
transfer restrictions or other related procedures as described in the 
Prospectus.

     5.   We agree that, during the applicable period as described in the 
Prospectus, ownership of Securities shall be represented by a global certificate
registered in the name of the applicable securities depository or its nominee, 
that we will not be entitled to receive any certificate representing the 
Securities and that our ownership of any Securities will be maintained in book 
entry form by the securities depository for the account of our agent member, 
which in turn will maintain records of our beneficial ownership. We authorize 
and instruct our agent member to disclose to the applicable trust company such 
information concerning our beneficial ownership of Securities as such trust 
company shall request.

     6.   We acknowledge that partial deliveries of Securities purchased in 
Auctions may be made to us and such deliveries shall constitute good delivery as
set forth in the Prospectus.

     7.   This letter is not a commitment by us to purchase any Securities.

     15.  In the case of each offer to purchase, purchase, offer to sell or sale
by us of Securities not registered under the Securities Act of 1933, as amended
(the "Act"), we represent and agree as follows:

     
          A.  We understand and expressly acknowledge that the Securities have
     not been and will not be registered under the Act and, accordingly, that
     the Securities may not be reoffered, resold or otherwise pledged,
     hypothecated or transferred unless an applicable exemption from the
     registration requirements of the Act is available.

          B.  We hereby confirm that any purchase of Securities made by us will 
     be for our own account, or for the account of one or more parties for which
     we are acting as trustee or agent with complete investment discretion and
     with authority to bind such parties, and not with a view to any public
     resale or distribution thereof. We and each other party for which we are
     acting which will acquire Securities will be "accredited investors" within
     the meaning of Regulation D under the Act with respect to the Securities to
     be purchased by us or such party, as the case may be, will have previously
     invested in similar types of instruments and will be able and prepared to
     bear the economic risks of investing in and holding such Securities.

          C.  We acknowledge that prior to purchasing any Securities we shall
     have received a Prospectus (private placement memorandum) with respect
     thereto and acknowledge that we will have had access to such financial and
     other information, and have been afforded the opportunity to ask such
     questions of representatives of the Corporation and receive answers
     thereto, as we deem necessary in connection with our decision to purchase
     Securities.

          D.  We recognize that the Corporation and broker-dealers will rely
     upon the truth and accuracy of the foregoing investment representations and
     agreements, and we agree that each of our purchases of Securities now or in
     the future shall be deemed to constitute our concurrence in all of the
     foregoing which shall be binding on us and each party for which we are
     acting as set forth in Subparagraph B above.

                                     -31-
<PAGE>
 
                                    PART I

          1.   Designation.

          The designation of said series of Preferred Stock shall be Flexible 
Auction Preferred Stock, Series D (the "Series D Stock"). The number of shares 
of Series D Stock shall be 600. The stated value of the Series D Stock shall be 
$100,000 per share.

          2.   Dividends.

          (a) The Holders (as defined in Section 9 of this Part I) shall be 
entitled to receive, when, as and if declared by the Board of Directors (as 
defined in Section 9 of this Part I) out of funds legally available therefor, 
cumulative cash dividends, at the Applicable Rate (as defined in clause 
(c)(i)(A) of this Section 2) per annum, determined as set forth below, and no 
more, payable on the respective dates set forth below.

          (b)(i)  Dividends on shares of Series D Stock shall accrue at the 
Applicable Rate from the Date of Original Issue (as defined in Section 9 of this
Part I).

          (b)(ii)  Accrued dividends on the shares of the Series D Stock shall 
be payable commencing on August 15, 1990. Thereafter, dividends on the Series D
Stock for a Short-Term Dividend Period (as defined in subparagraph (b)(vi) of 
this Section 2) shall be payable on the last day of such Short-Term Dividend 
Period. Dividends on the shares of Series D Stock for a Long-Term Dividend 
Period (as defined in subparagraph (b)(vi) of this Section 2) shall be payable 
on the last day of such Long-Term Dividend Period and, if occurring prior to the
last day of such Long-Term Dividend Period, on the first day of the fourth month
after the commencement of such Long-Term Dividend Period and quarterly 
thereafter on the first day of each succeeding third month. Each day on which
dividends would be payable as determined as set forth in this subparagraph (ii)
but for the provisions set forth in subparagraph (b)(iii) of this paragraph 2 is
referred to herein as a "Normal Dividend Payment Date."

          (b)(iii)  Notwithstanding the preceding subparagraph (ii) of this 
paragraph (b), if:

          (A)(1)  the Securities Depository (as defined in Section 9 of
     this Part I) shall not have advised the Trust Company (as defined in
     Section 9 of this Part I) at least five Business Days prior to a
     Dividend Payment Date that it will make available to its participants
     and members on Dividend Payment Dates, in funds immediately available
     in New York City, the amount due as dividends on such Dividend Payment
     Dates, and (2)(X) a Normal Dividend Payment Date is not a Business Day
     (as defined in Section 9 of this Part I) or (Y) the day next
     succeeding such Dividend Payment Date is not a Business Day, then
     dividends shall be payable on the first Business Day preceding such
     Normal Dividend Payment Date that is next succeeded by a Business Day;
     or

          (B)(1)  the Securities Depository shall have advised the Trust
     Company at least five Business Days prior to such Dividend Payment
     Date that it will make available to its participants and members on
     Dividend Payment Dates, in funds immediately available in New York
     City, the amount due as dividends on such

                                     -32-
<PAGE>
 
     Dividend Payment Dates and (2) a Normal Dividend Payment Date is not a
     Business Day, then Dividends shall be payable on the first Business Day
     after such Normal Dividend Payment Date;

          (b)(iv) Notwithstanding the foregoing, if the date on which dividends 
on the shares of the Series D Stock would be payable as determined as set forth 
in subparagraphs (ii) and (iii) of this paragraph (b) is a day that would result
in the number of days between successive Auction Dates (as defined in Section 9 
of this Part I) for the Series D Stock (determined by including the first 
Auction Date and excluding the second Auction Date) not being at least equal to 
the then current Minimum Holding Period (as defined below), then dividends on 
such shares shall be payable, if clause (iii) (A) above would be applicable to 
the Series D Stock, on the first Business Day following such date on which 
dividends would be so payable that is next succeeded by a Business Day or, if 
clause (iii)(B) above would be applicable to the Series D Stock, on the first 
Business Day following such day on which dividends would be so payable, that in 
either case results in the number of days between such successive Auction Dates 
for the Series D Stock (determined as set forth above) being at least equal to 
the then current Minimum Holding Period.

          In addition, notwithstanding the foregoing, the Board of Directors, in
the event of a change in law lengthening the minimum holding period (the 
"Minimum Holding Period") (currently found in Section 246(c) of the Code (as 
defined in Section 9 of this Part I) required for taxpayers to be entitled to 
the dividends-received deduction on Preferred Stock held by nonaffiliated 
corporations (currently found in Section 243(a) of the Code), shall adjust the 
period of time between Dividend Payment Dates (as hereinafter defined) so as, 
subject to clauses (A) and (B) of subparagraph (b)(iii), to adjust uniformly the
number of Dividend Period Days (as defined in Section 9 of this Part I) in 
Short-Term Dividend Periods (as defined in subparagraph (b)(vi) of this Section 
2) commencing after the date of such change in law to exceed the new Minimum 
Holding Period, provided that the number of Dividend Period Days shall not 
exceed by more than nine days the length of such new Minimum Holding Period and 
in no event shall exceed 98 days and shall consist of a whole number of weeks.

          (b)(v) Each date on which dividends on the shares of the Series D 
Stock shall be payable as determined as set forth above shall be referred to
herein as a "Dividend Payment Date" and the first Dividend Payment Date shall be
referred to herein as the "Initial Dividend Payment Date." If applicable, the
period from the preceding Dividend Payment Date to and including the next
Dividend Payment Date for the Series D Stock during a Long-Term Dividend Period
is herein referred to as a "Dividend Quarter." Although any particular Dividend
Payment Date for the Series D Stock may not occur on the originally scheduled 
Normal Dividend Payment Date for the Series D Stock because of the foregoing 
provisions, each succeeding Dividend Payment Date for the Series D Stock shall 
be, subject to such provision, the date determined as set forth in subparagraph 
(ii) above as if each preceding Dividend Payment Date had occurred on the 
respective originally scheduled Normal Dividend Payment Date.

          (b)(vi) The period from and after the Date of Original Issue to and 
including the Initial Dividend Payment Date (the "Initial Dividend Period") for 
the shares of Series D Stock shall contain 48 Dividend Period Days. After the 
Initial Dividend Period for the Series D Stock, each subsequent Dividend Period 
for the Series D Stock (except for the adjustments for non-Business Days 
provided in subparagraph (iii) above) shall contain 49 Dividend Period Days 
(each such period, subject to any adjustment as a result of a change in law 
lengthening the Minimum Holding

                                     -33-
<PAGE>
 
Period as provided in subparagraph (iv) above, being referred to herein as a 
"Short-Term Dividend Period"), unless as provided in subparagraph (vii) below, 
the Term Selection Agent specifies that any such subsequent Dividend Period 
shall be a Dividend Period containing any specified number of Dividend Period 
Days greater than the number of Dividend Period Days in a Short-Term Dividend 
Period and containing a number of Dividend Period Days evenly divisible by seven
(each such period being referred to herein as a "Long-Term Dividend Period," and
each such Short-Term Dividend Period and Long-Term Dividend Period, together 
with the Initial Dividend Period (as defined in clause (c)(i)(A)), being 
referred to herein as a "Dividend Period"). After the Initial Dividend Period 
for the Series D Stock, each successive Dividend Period for the Series D Stock 
shall commence on the Dividend Payment Date ending the preceding Dividend Period
and shall end (i) during a Short-Term Dividend Period, on the next Dividend
Payment Date for the Series D Stock and (ii) during a Long-Term Dividend Period,
on the last day of the Long-Term Dividend Period specified by the Term Selection
Agent in the related notice of Long-Term Dividend Period.

          (b)(vii) Not less than 10 and not more than 20 days prior to the date 
of an Auction (as defined in Section 9 of this Part I) for the Series D Stock 
and based on the criteria set forth below, the Term Selection Agent may give 
telephonic and written notice to the Corporation, the Trust Company, the Paying 
Agent and the Securities Depository that the next succeeding Dividend Period for
the Series D Stock will be longer than a Short-Term Dividend Period (a "Notice 
of Long-Term Dividend Period"). Such notice will specify the next succeeding 
Dividend Period for the Series D Stock as a Long-Term Dividend Period, which may
be any period designated by the Term Selection Agent greater than the Short-Term
Dividend Period and containing a number of Dividend Period Days evenly divisible
by seven, provided that for any Auction occurring after the initial Auction for
the Series D Stock, the Term Selection Agent may not give a Notice of Long-Term
Dividend Period for the Series D Stock (and any such notice shall be null and
void) unless Sufficient Clearing Bids were made in the last occurring Auction
for the Series D Stock and full cumulative dividends for the Series D Stock 
payable prior to the date of Notice of Long-Term Dividend Period have been paid 
in full. The Term Selection Agent shall state in each Notice of Long-Term 
Dividend Period (i) that the next succeeding Dividend Period for the Series D 
Stock shall be a Long-Term Dividend Period, (ii) the term thereof and (iii) the 
redemption provisions applicable for such Long-Term Dividend Period. The Term
Selection Agent may establish a Long-Term Dividend Period, and, subject to the
provisions of Section 4 of this paragraph 6(c) of Article Fourth, the applicable
redemption provisions therefor, for the shares of the Series D Stock if the Term
Selection Agent determines that such Long-Term Dividend Period and such 
redemption provisions, in its sole opinion, provide the Corporation with the 
most favorable financing alternative based upon the following: (i) short-term 
and long-term market rates and indices of such short-term and long-term rates, 
(ii) the amounts, maturities and interest or dividend rates on the then 
outstanding securities of the Corporation or its subsidiaries, (iii) market 
supply and demand for short-term and long-term securities, (iv) yield curves for
short-term and long-term securities comparable to the shares of the Series D 
Stock, (v) industry and financial conditions which may affect the shares of the 
Series D Stock including the Term Selection Agent's expectations with respect 
thereto, (vi) current tax laws and administrative interpretations with respect 
thereto, (vii) the number of shares of the Series D Stock Outstanding on the 
next Auction Date and (viii) the number of potential purchasers. Any Notice of 
Long-Term Dividend Period may be revoked by the Term Selection Agent on or prior
to the second Business Day prior to the related Auction by telephonic and 
written notice (a "Notice of Revocation") to the Corporation, the Trust Company,
the Paying Agent and the Securities Depository, specifying that the Term 
Selection Agent has determined that because of subsequent changes in any of the 
foregoing factors, such Long-Term Dividend Period would not result in the 

                                     -34-
<PAGE>
 
most favorable financing alternative for the Corporation, and shall be deemed to
have been revoked if on or prior to the second Business Day prior to the related
Auction, the Term Selection Agent shall have been removed and the Corporation
shall have given written and telephonic notice of such removal ("Notice of
Removal") to the Trust Company, the Paying Agent and the Securities Depository.
Except with respect to a Notice of Long-Term Dividend Period that is deemed to
be revoked, any Long-Term Dividend Period specified by the Term Selection Agent
for the Series D Stock and any revocation thereof shall be conclusive and
binding on the Corporation and the Holders.

          The Corporation may remove the Term Selection Agent for the Series D 
Stock upon 5 days' written notice. If there is no Term Selection Agent with 
respect to any Dividend Period, then such Dividend Period shall be a Short-Term 
Dividend Period.

          If the Term Selection Agent does not give a Notice of Long-Term 
Dividend Period with respect to the next succeeding Dividend Period for the 
Series D Stock or gives a Notice of Revocation with respect thereto or such 
Notice of Long-Term Dividend Period shall be deemed to have been revoked, such 
next succeeding Dividend Period shall be a Short-Term Dividend Period. In 
addition, in the event the Term Selection Agent has given a Notice of Long-Term 
Dividend Period with respect to the next succeeding Dividend Period for the 
Series D Stock and has not given a Notice of Revocation with respect thereto and
such Notice of Long-Term Dividend Period shall not have been deemed revoked, but
Sufficient Clearing Bids are not made in the related Auction for the Series D
Stock or such Auction is not held for any reason, such next succeeding Dividend
Period shall, notwithstanding such Notice of Long-Term Dividend Period, be a
Short-Term Dividend Period and the Term Selection Agent may not again give a
Notice of Long-Term Dividend Period (and any such notice shall be null and void)
for the Series D Stock until sufficient Clearing Bids have been made in an
Auction with respect to a Short-Term Dividend Period for the Series D Stock.

          (b)(viii) As long as the Applicable Rate is based on the results of 
an Auction, the Corporation shall pay to the Paying Agent (as defined in 
Section 9 of this Part I) not later than 12:00 noon, New York City time, on the
Business Day next preceding each Dividend Payment Date, an aggregate amount of
funds available on the next Business Day in the City of New York, New York,
equal to the dividends to be paid to all Holders on such Dividend Payment Date.
All such moneys shall be held in trust for the payment of such dividends by the
Paying Agent for the benefit of the Holders specified in subparagraph (ix) or
this paragraph (b).

          (b)(ix)   Each dividend shall be payable to the Holders as their names
appear on the stock register of the Corporation on the Business Day next
preceding the Dividend Payment Date thereof; provided, however, that if a Rate
Adjustment Event (as defined in Section 9 of this Part I) shall have occurred
and shall not have been cured by paying all accrued and unpaid dividends
and unpaid redemption payments as provided in clause (c)(i)(B), such dividend
shall be paid to such Holders as their names appear on the stock register of the
Corporation on such date, not exceeding 15 days preceding the payment date
thereof, as may be fixed by the Board of Directors. Dividends in arrears for any
past Dividend Period may be declared and paid at any time, without reference to
any regular Dividend Payment Date, to the Holders as their names appear on the
stock register of the Corporation on such date, not exceeding 15 days preceding
the payment date thereof, as may be fixed by the Board of Directors.

                                     -35-
<PAGE>
 
          (c)(i)(A) The dividend rate of shares of Series D Stock shall be 6.55%
per annum during the Initial Dividend Period. Commencing on the Initial Dividend
Payment Date, the dividend rate on shares of Series D Stock for each subsequent
dividend period (hereinafter referred to as a "Subsequent Dividend Period" and
collectively as "Subsequent Dividend Periods") thereafter, which Subsequent
Dividend Periods shall commence on the day that is the last day of the preceding
Dividend Period and shall end on and include the next succeeding Dividend
Payment Date, shall be equal to the rate per annum that results from
implementation of the Auction Procedures (as defined in Section 9 of this Part
I); provided, however, that in the event that an Auction for any Dividend Period
is not held for any reason (other than as a result of the existence of a Rate
Adjustment Event on the Auction Date for such Dividend Period), the dividend
rate for such Dividend Period shall be the Non-Auction Rate on the Auction Date
with respect to such Dividend Period. The "Non-Auction Rate" on an Auction Date
shall be the greater of (x) the Applicable Rate in effect immediately prior to
such Auction Date or (y) the Maximum Rate in effect on such Auction Date for a
Short-Term Dividend Period, regardless of whether an Auction is held. The
dividend rate for any Dividend Period or part thereof determined as set forth in
this paragraph (c) is referred to herein as the "Applicable Rate" for such
Dividend Period or part thereof.

          (c)(i)(B) In the event a Rate Adjustment Event occurs on a Dividend
Payment Date and is not cured in accordance with the next succeeding sentence.
Auctions will be suspended until such time as set forth below, and the
Applicable Rate for each Dividend Period thereafter (until Auctions are
resumed), including the Dividend Period commencing on the date of such Rate
Adjustment Event, shall be equal to the Maximum Rate with respect to such
Dividend Period (but, for purposes of determining such Maximum Rate, with the
prevailing rating for the Series D Stock being deemed to be "Below ba3"/BB-" and
the first day of such Dividend Period being deemed to be the Auction Date) and
each such Dividend Period shall be a Short-Term Dividend Period. Any such Rate
Adjustment Event shall be deemed cured if by 12:00 noon, New York City time, on
the third Business Day next succeeding any such Rate Adjustment Event, the
Corporation shall have deposited with the Trust Company all accumulated and
unpaid dividends and any unpaid redemption payments, including the full amount
of any dividends to be paid with respect to the Dividend Period with respect to
which such Rate Adjustment Event occurred, plus an amount computed by
multiplying (i) 250% of the 60-Day "AA" Composite Commercial Paper Rate on the
date on which such Rate Adjustment Event occurred by (ii) a fraction, the
numerator of which shall be the number of days for which such Rate Adjustment
Event is not cured in accordance with this sentence (including the day such Rate
Adjustment Event occurs and excluding the day such Rate Adjustment Event is
cured) and the denominator of which shall be 360, and applying the rate obtained
against the aggregate amount not paid when due.

          9(c)(ii)   In the event a Rate Adjustment Event occurs during a Long-
Term Dividend Period, the Applicable Rate for such Dividend Period shall remain
unchanged, and an additional amount computed by multiplying (i) the Maximum Rate
with respect to such Dividend Period (but, for purposes of determining such
Maximum Rate, with the prevailing rating for the Series D Stock being deemed to
be "Below "ba3"/BB-" and the date of such Rate Adjustment Event being deemed to
be the Auction Date) by (ii) a fraction, the numerator of which shall be the
number of days for which such Rate Adjustment Event is not cured (including the
day such Rate Adjustment Event occurs and excluding the day such Rate Adjustment
Event is cured) and the denominator of which shall be 360, and applying the rate
obtained against accumulated dividends and redemption payments not paid when
due, shall accumulate as additional dividends on the shares of the Series D
Stock. In the event that such Rate Adjustment Event is not cured prior to the
next succeeding

                                     -36-
<PAGE>
 
Auction Date for shares of the Series D Stock, Auctions for the Series D Stock
shall be suspended, the next succeeding Dividend Period shall be a Short-Term
Dividend Period and the Applicable Rate shall be equal to the Maximum Rate with
respect to such Dividend Period (but, for purposes of determining such Maximum
Rate, with the prevailing rating for the Series D Stock being deemed to be
"Below "ba3"/BB-" and the first day of such Dividend Period being deemed to be
the Auction Date). Thereafter until such Rate Adjustment Event shall have been
cured and full and cumulative dividends on the shares of the Series D Stock
shall have been paid in full or the Board of Directors of the Corporation shall
have declared a dividend in such amount and funds sufficient for the payment
thereof shall have been irrevocably deposited with the Paying Agent, each
subsequent Dividend Period and Applicable Rate for the Series D Stock will be
determined pursuant to the next preceding paragraph.

          (c)(iii)  If prior to an Auction Date for shares of the Series D
Stock, full and cumulative dividends shall have been paid in full or the Board
of Directors of the Corporation shall have declared a dividend in such amount
and funds sufficient for the payment thereof shall have been irrevocably
deposited with the Paying Agent, and any unpaid redemption payments shall have
been made, Auctions for the Series D Stock will resume.

          (c)(iv)   The amount of dividends per share accrued and payable on
shares of Series D Stock for each Dividend Period or Dividend Quarter shall be
computed by multiplying the Applicable Rate for such Dividend Period or Dividend
Quarter by a fraction, the numerator of which shall be the number of Dividend
Period Days in such Dividend Period or Dividend Quarter (calculated by counting
the first day of such Dividend Period or Dividend Quarter but excluding the last
day thereof), and the denominator of which shall be 360 and applying the rate
obtained against $100,000; and the amount of dividends per share accrued for any
part of any Dividend Period shall be computed by multiplying the Applicable Rate
for such Dividend Period by a fraction the numerator of which shall be the
number of days in such part of such Dividend Period (calculated by counting the
first day thereof but excluding the last day thereof) and the denominator of
which shall be 360 and applying the rate obtained against $100,000.

          (d)(i)    No full dividends shall be declared or paid or set apart
for payment on Preferred Stock of any series ranking, as to dividends, on a
parity with or junior to the Series D Stock for any period unless full
cumulative dividends have been or contemporaneously are declared and paid or
declared and a sum sufficient for the payment thereof set apart for such payment
on the Series D Stock for all Dividend Periods terminating on or prior to the
date of payment of such full cumulative dividends. When dividends are not paid
in full, as aforesaid, upon the Series D Stock and any other Preferred Stock
ranking on a parity as to dividends with the Series D Stock, all dividends
declared upon the Series D Stock and any other Preferred Stock ranking on a
parity as to dividends with the Series D Stock shall be declared pro rata so
that the amount of dividends declared per share on the Series D Stock and such
other Preferred Stock shall in all cases bear to each other the same ratio that
accrued dividends per share on the Series D Stock and such other Preferred Stock
bear to each other. Holders of Series D Stock shall not be entitled to any
dividend, whether payable in cash, property or stocks, in excess of the full
cumulative dividends, as herein provided, on the Series D Stock. No interest, or
sum of money in lieu of interest, shall be payable in respect of any dividend
payments on the Series D Stock which may be in arrears.

          (d)(ii)   So long as any shares of Series D Stock are outstanding, no
dividend (other than a dividend in Common Stock or in any other stock-ranking
junior to Series D Stock as to

                                     -37-

dividends and upon liquidation and other than as provided in subparagraph (i) of
this paragraph (d)) shall be declared or paid or set aside for payment or other 
distribution declared or made upon the Common Stock or upon any other stock 
ranking junior to or on a parity with the Series D Stock as to dividends or upon
liquidation, nor shall any Common Stock or any other stock of the Corporation 
ranking junior to or on a parity with the Series D Stock as to dividends or upon
liquidation be redeemed, purchased or otherwise acquired for any consideration 
(or any moneys paid to or made available for a sinking fund for the redemption 
of any such stock) by the Corporation (except by conversion into or exchange for
stock of the Corporation ranking junior to the Series D Stock as to dividends 
and upon liquidation) unless, in each case, the full cumulative dividends on all
outstanding shares of Series D Stock shall have been paid for all past Dividend 
Periods.

          3.   Voting.

          (a)  Unless the vote or consent of the holders of a greater number of 
shares shall then be required by law, the consent of the holders of at least 
66-2/3% of all of the shares of the Series D Stock and all other series of 
Preferred Stock ranking on a parity with the Series D Stock, either as to 
dividends or upon liquidation, at the time outstanding given in person or by 
proxy either in writing or by a vote at a meeting called for the purpose at 
which the holders of shares of Series D Stock and shares of Preferred Stock 
ranking on a parity with the Series D Stock, either as to dividends or upon 
liquidation, shall vote together as a separate class, shall be necessary for 
authorizing, effecting or validating the amendment, alteration or repeal of any 
of the provisions of this Restated Certificate of Incorporation or of any 
certificate amendatory thereof or supplemental thereto (including any 
Certificate of Designations or any similar document relating to the Series D 
Stock or any series of Preferred Stock ranking on a parity with the Series D 
Stock, either as to dividends or upon liquidation) which would adversely affect
the powers, preferences, rights or privileges of the Series D Stock or the 
Preferred Stock ranking on a parity with the Series D Stock, either as to 
dividends or upon liquidation; provided, however, that if any such amendment, 
alteration or repeal would adversely affect the powers, preferences, rights or 
privileges of the Series D Stock or one or more series of the Preferred Stock 
or ranking on a parity with the Series D Stock, either as to dividends or upon 
liquidation, but shall not so affect the entire class, then only the shares of 
the one or more series so affected shall be considered to be a separate class 
entitled to vote upon or consent to such amendment, alteration or repeal;

          (b)  Unless the vote or consent of the holders of a greater number of 
shares shall then be required by law, the consent of the holders of at least 
66-2/3% of all of the shares of the Series D Stock and all other series of 
Preferred Stock ranking on a parity with the Series D Stock, either as to 
dividends or upon liquidation, at the time outstanding, given in person or by 
proxy, either in writing or by a vote at a meeting called for the purpose at 
which the holders of shares of the Series D Stock and such other series of
Preferred Stock ranking on a parity with the Series D Stock, either as to 
dividends or upon liquidation, shall vote together as a single class without 
regard to series, shall be necessary for authorizing, effecting or validating 
the creation, authorization or issue of any class of stock of the Corporation 
ranking prior to the shares of the Series D Stock and such other series of 
Preferred Stock ranking on a parity with the Series D Stock, either as to 
dividends or upon liquidation, as to dividends or upon liquidation, or the 
reclassification of any authorized stock of the Corporation into any such prior 
shares, or the creation, authorization or issue of any obligation or security 
convertible into or evidencing the right to purchase any such prior shares; and

                                     -38-
<PAGE>
 
          (c)  If at the time of any annual meeting of stockholders for the 
election of directors a default in preference dividends on the Series D Stock or
the Preferred Stock ranking on a parity with the Series D Stock, either as to 
dividends or upon liquidation, shall exist, the number of directors constituting
the Board of Directors shall be increased by two, and the holders of the Series 
D Stock and the Preferred Stock of all series ranking on a parity with the 
Series D Stock, either as to dividends or upon liquidation, shall have the right
at such meeting, voting together as a single class without regard to series, to
the exclusion of the holders of Common Stock, to elect two directors of the 
Corporation to fill such newly created directorships. Such right shall continue
until there are no dividends in arrears upon the Series D Stock and the 
Preferred Stock ranking on a parity with the Series D Stock, either as to 
dividends or upon liquidation. Each director elected by the holders of shares of
Series D Stock and Preferred Stock ranking on a parity with the Series D Stock, 
either as to dividends or upon liquidation, (herein called a "Preferred 
Director") shall continue to serve as such director for the full term for which 
he shall have been elected, notwithstanding that prior to the end of such term a
default in preference dividends shall cease to exist. Any Preferred Director may
be removed without cause by, and shall not be removed without cause except by, 
the vote of the holders of record of the outstanding shares of Series D stock 
and Preferred Stock ranking on a parity with the Series D Stock, either as to 
dividends or upon liquidation, voting together as a single class without regard 
to series, at a meeting of the stockholders, or of the holders of shares of 
Series D Stock and Preferred Stock ranking on a parity with the Series D 
Stock, either as to dividends or upon liquidation, called for that purpose. So 
long as a default in preference dividends on the Series D Stock or the Preferred
Stock ranking on a parity with the Series D Stock, either as to dividends or
upon liquidation shall exist, (A) any vacancy in the office of a Preferred
Director may be filled (except as provided in the following clause (B)) by an
instrument in writing signed by the remaining Preferred Director and filed with
the Corporation and (B) in the case of the removal of any Preferred Director,
the vacancy may be filled by the vote of the holders of the outstanding shares
of Series D Stock and Preferred Stock ranking on a parity with the Series D
Stock, either as to dividends or upon liquidation, voting together as a single
class without regard to series, at the same meeting at which such removal shall
be voted. Each director appointed as aforesaid by the remaining Preferred
Director shall be deemed, for all purposes hereof, to be a Preferred Director.
Whenever the term of office of the Preferred Directors shall end and a default
in preference dividends shall no longer exist, the number of directors
constituting the Board of Directors shall be reduced by two. For the purposes
hereof, a "default in preference dividends" on the Series D Stock or the
Preferred Stock ranking on a parity with the Series D Stock, either as to
dividends or upon liquidation, shall be deemed to have occurred whenever the
amount of accrued dividends upon the Series D Stock or any series of the
Preferred Stock ranking on a parity with the Series D Stock, either as to
dividends or upon liquidation, shall be equivalent to six full quarterly
dividends (which, with respect to any Series D Stock providing for other than
quarterly dividend periods, shall be deemed to be dividends in respect of a
number of dividend periods containing not less than 540 days) or more, and,
having so occurred, such default shall be deemed to exist thereafter until, but
only until, all accrued dividends on all shares of Series D Stock and Preferred
Stock ranking on a parity with the Series D Stock, either as to dividends or
upon liquidation, of each and every series then outstanding shall have been paid
to the end of the last preceding dividend period.

          4.   Redemption.

          (a)(i) The Series D Stock may be redeemed, at the option of the 
Corporation, as a whole or from time to time in part, (A) in the case of a 
Short-Term Dividend Period, on the 

                                     -39-
<PAGE>
 
Dividend Payment Date for such period and (B) in the case of a Long-Term
Dividend Period, on such Dividend Payment Dates as may be established by the
Term Selection Agent as redemption dates, and on such other terms as may be
established by the Term Selection Agent, such dates and other terms have been
determined by the Term Selection Agent as the dates and terms which provide the
Corporation with the most favorable financing alternatives, such determination
to be based upon the factors listed in clauses (i)-(viii) of subparagraph 2(b)
(vii) hereof at a redemption price of $100,000 per shares plus an amount equal
to accrued and unpaid dividends thereon (whether or not earned or declared) to
the date fixed for redemption.

          (a)  (ii) If fewer than all of the outstanding shares of Series D
Stock are to be redeemed pursuant to subparagraph (i) of this paragraph (a), the
number of shares to be redeemed shall be determined by the Board of Directors,
and such shares shall be redeemed pro rata from the Holders in proportion to the
number of such shares held by such Holders (with adjustments to avoid redemption
of fractional shares).

          (b)  If the Corporation shall redeem shares of Series D Stock pursuant
to paragraph (a) of this Section 4, notice of such redemption shall be given by 
mailing the same by first class mail, postage prepaid, not less than 30 nor more
than 45 days prior to the date fixed for redemption thereof, to each Holder of 
the shares to be redeemed, at such Holder's address as the same appears on the 
stock register of the Corporation. Such notice shall state: (i) the redemption 
date; (ii) the number of shares of Series D Stock to be redeemed; (iii) the 
redemption price plus the amount of accrued and unpaid dividends to the 
redemption date; (iv) the place or places where certificates for such shares of 
Series D Stock are to be surrendered for payment of the redemption price; and 
(v) that dividends on the shares to be redeemed will cease to accrue on such 
redemption date. If fewer than all shares held by any Holder are to be redeemed,
the notice mailed to such Holder shall also specify the number of shares to be 
redeemed from such Holder.

          (c)  Notwithstanding the provisions of paragraph (a) of this Section 
4, if any dividends on the Series D Stock are in arrears, no shares of Series D 
Stock shall be redeemed unless all outstanding shares of Series D Stock are 
simultaneously redeemed, and the Corporation shall not purchase or otherwise 
acquire any shares of Series D Stock; provided, however, that the foregoing 
shall not prevent the purchase or acquisition of shares of Series D Stock 
pursuant to a purchase or exchange offer made on the same terms to Holders of 
all outstanding shares of Series D Stock.

          (d)  If notice of redemption has been given under paragraph (b) of 
this Section 4 or the Corporation has irrevocably authorized and directed the 
Redemption Agent to begin promptly and complete such giving of notice, and the 
Corporation has deposited in trust with the Redemption Agent funds necessary for
such redemption, from and after the later of the date of such notice or the date
such deposit is made, the shares of Series D Stock called for redemption shall 
no longer be deemed to be outstanding, and all rights of the Holders thereof as 
stockholders of the Corporation (except the right to receive the redemption 
price plus an amount equal to the accrued and unpaid dividends thereon to the 
date fixed for redemption) shall cease. Upon surrender in accordance with said 
notice of the certificates for any shares so redeemed (properly endorsed or 
assigned for transfer, if the Board of Directors shall so require and the notice
shall so state), the redemption price set forth above plus an amount equal to 
such accrued and unpaid dividends shall be paid by the Redemption Agent to the 
Holders of the shares of Series D Stock subject to redemption as set forth in 
paragraph (c) of this Section 4. In case fewer than all of the 

                                     -40-
<PAGE>
 
shares represented by any such certificate are redeemed, a new certificate shall
be issued representing the unredeemed shares without cost to the Holder thereof.

          (e)  As long as the Applicable Rate is based on the results of an 
Auction, on the Business Day immediately preceding the date fixed for 
redemption, the Corporation shall pay the applicable Redemption Deposit Amount 
(as defined in Section 9 of this Part I) to the Redemption Agent, in funds 
available on the redemption date for disbursement to Holders as appropriate. All
such moneys shall be held in trust by the Redemption Agent for the benefit of 
Holders of shares so to be redeemed.

          5.  Liquidation Rights.

          (a) Upon the dissolution, liquidation or winding up of the
Corporation, the Holders of the Series D Stock shall be entitled to receive out
of the assets of the Corporation available for distribution to stockholders,
before any payment or distribution shall be made on the Common Stock or on any
other class of stock ranking junior to the Series D Stock upon liquidation, the
amount of $100,000 per share, plus a sum equal to all dividends (whether or not
earned or declared) on such shares accrued and unpaid thereon to the date of the
final distribution.

          (b)  Neither the sale of all or substantially all the property or 
business of the Corporation, nor the merger or consolidation of the Corporation
into or with any other corporation or the merger or consolidation of any other
corporation into or with the Corporation, shall be deemed to be a dissolution,
liquidation or winding up, voluntary or involuntary, for the purposes of this
Section 5.

          (c)  After the payment to the holders of the Series D Stock of the 
full preferential amounts provided for in this Section 5, the holders of Series
D Stock as such shall have no right or claim to any of the remaining assets of
the Corporation.

          (d)  In the event the assets of the Corporation available for 
distribution to the holders of Series D Stock upon any dissolution, liquidation 
or winding up of the Corporation, whether voluntary or involuntary, shall be 
insufficient to pay in full all amounts to which such holders are entitled 
pursuant to paragraph (a) of this Section 5, no such distribution shall be made 
on account of any shares of any other class or series of Preferred Stock ranking
on a parity with the Series D Stock upon such dissolution, liquidation or 
winding up unless proportionate distributive amounts shall be paid on account 
of the Series D Stock, ratably, in proportion to the full distributable amounts 
for which holders of all such parity shares are respectively entitled upon such 
dissolution, liquidation or winding up.

          (e)  Upon the dissolution, liquidation or winding up of the 
Corporation, the holders of shares of Series D Stock then outstanding shall be 
entitled to be paid out of the assets of the Corporation available for 
distribution to its stockholders all amounts to which such holders are entitled 
pursuant to paragraph (a) of this Section 5 before any payment shall be made to 
the holders of any class or series of capital stock of the Corporation ranking 
junior upon liquidation to the Series D Stock.

          6.  Sinking or Retirement Fund.

                                     -41-
<PAGE>
 
          The Series D Stock shall not be entitled to the benefit of a sinking 
or retirement fund to be applied to the purchase or redemption of such stock.

          7.  Rank.

          For purposes of this paragraph 6(c) of Article Fourth, any stock of 
any class or classes of the Corporation shall be deemed to rank:

          (a) prior to the Series D Stock, either as to dividends or upon
liquidation, if the holders of such class or classes shall be entitled to the
receipt of dividends or of amounts distributable upon dissolution, liquidation
or winding up of the Corporation, as the case may be, in preference or priority
to the holders of Series D Stock;

          (b) on a parity with the Series D Stock, either as to dividends or 
upon liquidation, whether or not the dividend rates, dividend payment dates or
redemption or liquidation prices per share or sinking fund provisions, if any,
are different from those of the Series D Stock, or if the holders of such stock
shall be entitled to the receipt of dividends or of amounts distributable upon
dissolution, liquidation or winding up of the Corporation, as the case may be,
in proportion to their respective dividend rates or liquidation prices, without
preference or priority, one over the other, as between the holders of such stock
and the holders of Series D Stock; and

          (c) junior to the Series D Stock, either as to dividends or upon
liquidation, if such class shall be Common Stock or if the holders of Series D
Stock shall be entitled to receipt of dividends or of amounts distributable upon
dissolution, liquidation or winding up of the Corporation, as the case may be,
in preference or priority to the holders of shares of such class or classes.

          8.  Additional Agreements.

          (a) Term Selection Agent.  The Corporation shall use its best efforts 
to maintain a Term Selection Agent with respect to the Series D Stock to act in 
accordance with the provisions set forth herein.

          (b) Trust Company.  The Corporation shall use its best efforts to
maintain a Trust Company with respect to the Series D Stock to act in accordance
with the provisions set forth herein.

          9.  As used in Parts I and II of this paragraph 6(c) of Article
Fourth, the following terms shall have the following meanings (with terms
defined in the singular having comparable meanings when used in the plural and
vice versa), unless the context otherwise requires:

          (a) "60-day 'AA' Composite Commercial Paper Rate," on any date,
     shall mean (i) the interest equivalent of the 60-day rate on
     commercial paper placed on behalf of issuers whose corporate bonds are
     rated "AA" by Standard & Poor's or its successor, or the equivalent of
     such rating by another rating agency, as such 60-day rate is made
     available on a discount basis or otherwise by the Federal Reserve Bank
     of New York for the immediately preceding Business Day prior to such
     date; or (ii) in the event that the Federal Reserve Bank of New York
     does not make available

                                     -42-
<PAGE>
 
     such a rate, then the arithmetic average of the interest equivalent of the
     60-day rate on commercial paper placed on behalf of such issuers, as quoted
     on a discount basis or otherwise by the Commercial Paper Dealers to the
     Trust Company for the close of business on the immediately preceding
     Business Day prior to such date. If any Commercial Paper Dealer does not
     quote a rate required to determine the 60-day "AA" Composite Commercial
     Paper Rate, the 60-day "AA" Composite Commercial Paper Rate shall be
     determined on the basis of the quotation or quotations furnished by the
     remaining Commercial Paper Dealer or Commercial Paper Dealers and any
     Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers
     selected by the Corporation to provide such rate or rates not being
     supplied by any Commercial Paper Dealer or Commercial Paper Dealers, as the
     case may be, or, if the Corporation does not select any such Substitute
     Commercial Paper Dealer or Substitute Commercial Paper Dealers, by the
     remaining Commercial Paper Dealer or Commercial Paper Dealers. If the Board
     of Directors shall adjust the number of Dividend Period Days pursuant to
     the second sentence of subparagraph (b)(iv) of Section 2 of this Part I,
     then (i) if the Dividend Period Days shall be 70 or more days but fewer
     than 85 days, such rate shall be the arithmetic average of the interest
     equivalent of the 60-day and 90-day rates on such commercial Paper, and
     (ii) if the Dividend Period Days shall be 85 or more days but 98 or fewer
     days, such rate shall be the interest equivalent of the 90-day rate on such
     commercial paper. For purposes of this definition, the "interest
     equivalent" of a rate stated on a discount basis (a "discount rate") for
     commercial paper maturing in a given number of days shall be equal to the
     quotient (rounded to the nearest one-thousandth (.001) of 1%) of (A) the
     discount rate divided by (B) the difference between (x) 1.00 and (y) a
     fraction the numerator of which shall be the product of the discount rate
     times the number of days in which such commercial paper matures and the
     denominator of which shall be 360.

          (b) "Applicable 'AA' Composite Commercial Paper Rate" for any Long-
     Term Dividend Period on any date, shall mean (A) in the case of any Long-
     Term Dividend Period of less than 70 Dividend Period Days, the interest
     equivalent of the 60-day rate, (B) in the case of any Long-Term Dividend
     Period of 70 Dividend Period Days or more but less than 85 Dividend Period
     Days, the arithmetic average of the interest equivalent of the 60-day and
     90-day rates, (C) in the case of any Long-Term Dividend Period of 85
     Dividend Period Days or more but less than 120 Dividend Period Days, the
     interest equivalent of the 90-day rate, (D) in the case of any Long-Term
     Dividend Period of 120 Dividend Period Days or more but less than 148
     Dividend Period Days, the arithmetic average of the interest equivalent of
     the 90-day and 180-day rates, (E) in the case of any Long-Term Dividend
     Period of 148 Dividend Period Days or more but less than 210 Dividend
     Period Days, the interest equivalent of the 180-day rate, (F) in the case
     of any Long-Term Dividend Period of 210 Dividend Period Days or more but
     less than 238 Dividend Period Days, the arithmetic average of the interest
     equivalent of the 180-day and 270-day rates and (G) in the case of any 
     Long-Term Dividend Period of 238 or more Dividend Period Days, the
     interest equivalent of the 270-day rate, on commercial paper placed on
     behalf of issuers whose corporate bonds are rated "AA" by Standard &
     Poor's or its successor, or the equivalent of such rating by another rating
     agency as made available on a discount basis or otherwise by the Federal
     Reserve Bank of New York

                                     -43-
<PAGE>
 
     for the Business Day immediately preceding such date or in the event that
     the Federal Reserve Bank of New York does not make available any such rate,
     then the arithmetic average of such rates, as quoted on a discount basis or
     otherwise, by the Commercial Paper Dealers, to the Trust Company for the
     close of business on the Business Day next preceding such date. If any
     Commercial Paper Dealer does not quote a rate required to determine the
     "AA" Composite Commercial Paper Rate, the "AA" Composite Commercial Paper
     Rate shall be determined on the basis of the quotation or quotations
     furnished by the remaining Commercial Paper Dealer or Commercial Paper
     Dealers and any Substitute Commercial Paper Dealer or Substitute Commercial
     Paper Dealers selected by the Corporation to provide such rate or rates not
     being supplied by any Commercial Paper Dealer or Commercial Paper Dealers,
     as the case may be, or, if the Corporation does not select any such
     Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers,
     by the remaining Commercial Paper Dealer or Commercial Paper Dealers. For
     purposes of this definition, the "interest equivalent" means the equivalent
     yield on a 360-day basis of a discount-basis security to an interest-
     bearing security.

          (c) "Applicable Rate" shall mean the rate per annum at which dividends
     are payable for any Dividend Period established pursuant to clause
     (c)(i)(A) of Section 2 of this Part I.

          (d) "Applicable Treasury Rate" on any date, which respect to the
     Series D Stock with a Long-Term Dividend Period of one year or more, shall
     mean the interest equivalent of the rate for direct obligations of the
     United States Treasury having an original maturity which is equal to, or
     next lower than, the length of such Long-Term Dividend Period, as published
     weekly by the Federal Reserve Board in "Federal Reserve Statistical Release
     H.15 (519)--Selected Interest Rates," or any successor publication by the
     Federal Reserve Board within five Business days preceding such date. In the
     event that the Federal Reserve Board does not publish such weekly per annum
     interest rate, or if such release is not yet available, the applicable
     Treasury Rate will be the arithmetic average of the secondary market bid
     rates as of approximately 3:30 p.m., New York City time, on the Business
     Day next preceding such date of the U.S. Government Securities Dealers
     obtained by the Trust Company (in the case of a determination of the
     Applicable Treasury Rate on any Auction Date) or the Corporation (in the
     case of a determination of such rate on any other day) for the issue of
     direct obligations of the United States Treasury, in an aggregate principal
     amount of at least $1,000,000, with a remaining maturity equal to, or next
     lower than, the number of Dividend Period Days in such Long-Term Dividend
     Period. If any U.S. Government Securities Dealer does not quote a rate
     required to determine the Applicable Treasury Rate, the Applicable Treasury
     Rate shall be determined on the basis of the quotation or quotations
     furnished by the remaining U.S. Government Securities Dealer or Dealers or
     any Substitute U.S. Government Securities Dealer or Dealers selected by the
     Corporation to provide such rate or rates not being supplied by any U.S.
     Government Securities Dealer or Dealers, as the case may be, or, if the
     Corporation does not select any such Substitute U.S. Government Securities
     Dealer or Dealers, by the remaining U.S. Government Securities Dealer or
     Dealers: provided that, in the event the Corporation is unable to cause
     such quotations to be furnished to the Trust

                                     -44-
<PAGE>
 
     Company (or, if applicable, to the Corporation) by such sources, the
     Corporation may cause such rates to be furnished to the Trust Company (or,
     if applicable, to the Corporation) by such alternative source as the
     Corporation in good faith deems to be reliable. For purposes of this
     definition, the "interest equivalent" of a rate stated on a discount basis
     shall be equal to the quotient of (A) the discount rate divided by (B) the
     difference between 1.00 and the discount rate.

          (e) "Auction" shall mean each periodic implementation of the Auction
     procedures.

          (f) "Auction Date" shall mean the Business Day next preceding the 
     first day of each Dividend Period after the Initial Dividend Period.

          (g) "Auction Procedures" shall mean the procedures for conducting 
     Auctions set forth in Part II hereof.

          (h) "Board of Directors" shall mean the Board of Directors of the
     Corporation or (except in the context of the voting rights provisions
     relating to the Series D Stock as provided for in Section 3 of this Part I)
     a duly authorized committee thereof.

          (i) "Business Day" shall mean a day on which the New York Stock
     Exchange, Inc. is open for trading and on which banks in neither The City
     of New York, New York, nor Chicago, Illinois, are authorized by law to
     close.

          (j) "Code" shall mean the Internal Revenue Code of 1986.

          (k) "Commercial Paper Dealers" shall mean Goldman, Sachs & Co., 
     Merrill Lynch, Pierce, Fenner & Smith Incorporated, Salomon Brothers Inc.
     and Shearson Lehman Hutton Inc. or, in lieu of any thereof, their
     respective affiliates or successors.

          (l) "Common Stock" shall mean all shares now or hereafter issued of
     any class of common stock of the Corporation presently authorized and any
     other shares of stock into which such stock may hereinafter be changed from
     time to time.

          (m) "Date of Original Issue" shall mean the date on which the
     Corporation originally issues shares of Series D Stock.

          (n) "Dividend Payment Date" shall have the meaning specified in 
     subparagraph (b)(v) of Section 2 of this Part I.

     Series D Stock subject to such Bids is greater than such excess, such Bids
     shall be considered valid up to the amount of such excess, and, solely for
     purposes of allocating compensation among the Broker-Dealers submitting
     Bids with the same rate, the number of shares of Series D Stock subject to
     each Bid with the same rate shall be reduced pro rata to cover the number
     of shares of Series D Stock equal to such excess;

          (ii)(C) subject to clause (A), if more than one Bid with different
     rates is submitted on behalf of such Existing Holder, such Bids shall be
     considered valid in the ascending order of their respective rates up to the
     amount of such excess; and

          (ii)(D) in any such event the number, if any, of such shares subject
     to Bids not valid under this subparagraph (ii) shall be treated as the
     subject of a Bid by a Potential Holder; and

          (iii) all Sell Orders shall be considered valid but only up to and
     including in the aggregate the excess of the number of Outstanding shares
     of Series D Stock held by such Existing Holder over the sum of the shares
     of Series D Stock subject to Hold Orders referred to in subparagraph (i)
     and valid Bids by Existing Holders referred to in subparagraph (ii) above.

     (e)  If more than one Bid is submitted on behalf of any Potential Holder,
each Bid submitted shall be a separate Bid with the rate therein specified.

     4.  Determination of Sufficient Clearing Bids, Winning Bid Rate and
Applicable Rate.

     (a)  Not earlier than the Submission Deadline on each Auction Date, the 
Trust Company shall assemble all Orders submitted or deemed submitted to it by 
the Broker-Dealers (each such Order as submitted or deemed submitted by a 
Broker-Dealer being hereinafter referred to individually as a "Submitted Hold 
Order," a "Submitted Bid" or a "Submitted Sell Order," as the case may be, or as
a "Submitted Order" and collectively as "Submitted Hold Orders," "Submitted 
Bids" or "Submitted Sell Orders," as the case may be, or as "Submitted Orders" 
and shall determine:

             (i)  the excess of the total number of Series D Stock over the
     number of Outstanding shares of Series D Stock that are the subject of
     Submitted Hold Orders (such excess being hereinafter referred to as the
     "Available Series D Stock");

            (ii)  from the Submitted Orders whether:

                    (A)  the number of Outstanding shares of Series D Stock that
            are the subject of Submitted Bids by Potential Holders specifying
            one or more rates equal to or lower than the Maximum Rate exceeds or
            is equal to the sum of:

                           (I) the number of Outstanding shares of Series D
                    Stock that are the subject of Submitted Bids by Existing
                    Holders specifying one or more rates higher than the Maximum
                    Rate, and

                          (II) the number of Outstanding shares of Series D
                    Stock that are subject to Submitted Sell Orders (in the
                    event of such excess or such equality (other than because
                    the sum of the number of shares of Series D Stock in clauses
                    (I) and (II) above is zero because all of the outstanding
                    shares of Series D Stock are the subject of Submitted Hold
                    Orders), such Submitted Bids in clause (A) above being
                    hereinafter referred to collectively as "Sufficient Clearing
                    Bids"); and

           (iii)  if Sufficient Clearing Bids exist, the lowest rate specified
     in the Submitted Bids (the "Winning Bid Rate") which if:

                    (A)(I)  each Submitted Bid from Existing Holders specifying
           such lowest rate and (II) all other Submitted Bids from Existing
           Holders specifying lower rates were accepted, thus entitling such
           Existing Holders to continue to hold the shares of Series D

                                     -55-
           



<PAGE>
 
           Stock that are the subject of such Submitted Bids; and

                    (B)(I) each Submitted Bid from Potential Holders
           specifying such lowest rate and (II) all other Submitted
           Bids from Potential Holders specifying lower rates were
           accepted, thus entitling the Potential Holders to purchase
           the shares of Series D Stock that are the subject of those
           Submitted Bids, would result in such Existing Holders
           described in clause (A) continuing to hold an aggregate
           number of Outstanding shares of Series D Stock which, when
           added to the number of Outstanding shares of Series D Stock
           to be purchased by such Potential Holders described in
           clause (B), would equal not less than the Available Series
           D Stock.

     (b) Promptly after the Trust Company has made the determinations pursuant
to paragraph (a) of this Section 4, the Trust Company shall advise the
Corporation of the Maximum Rate and, based on such determinations, the
Applicable Rate for the next succeeding Dividend Period as follows:

               (i)  if Sufficient Clearing Bids exist, that the
     Applicable Rate for the next succeeding Dividend Period shall be
     equal to the Winning Bid Rate so determined;

               (ii)  if Sufficient Clearing Bids do not exist (other than
     because all of the Outstanding shares of Series D Stock are the
     subject of Submitted Hold Orders), then (a) if the Term Selection
     Agent has not given a Notice of Long-Term Dividend Period with
     respect to the next succeeding Dividend Period or has given a
     Notice of Revocation with respect thereto or such Notice of Long-
     Term Dividend Period shall be deemed to have been revoked, the
     Applicable Rate for such next succeeding Dividend Period shall be
     the Maximum Rate on the Auction Date for a Short-Term Dividend
     Period and (b) if the Term Selection Agent has given a Notice of
     Long-Term Dividend Period with respect to the next succeeding
     Dividend Period and has not given a Notice of Revocation with
     respect thereto and such Notice of Long-Term Dividend Period
     shall not have been deemed revoked, such next succeeding Dividend
     Period shall, notwithstanding such Notice of Long-Term Dividend
     Period, be a Short-Term Dividend Period, and the Applicable Rate
     for such next succeeding Dividend Period shall be the greatest of
     (i) the Applicable Rate in effect immediately prior to the
     applicable Auction, (ii) the Maximum Rate on the Auction Date for
     a Short-Term Dividend Period or (iii) the Maximum Rate on the
     Auction Date for the specified Long-Term Dividend Period, or

                                     -56-

                
<PAGE>
 
               (iii) if all the Outstanding shares of Series D Stock
          are the subject of Submitted Hold Orders, that the
          Applicable Rate for the next succeeding Dividend Period
          shall (1) in the case of a Short-Term Dividend Period, be
          equal to 59% of the 60-day "AA" Composite Commercial Paper
          Rate in effect on the date of such Auction; and (2) in the
          case of a Long-Term Dividend Period, 59% of the Reference
          Rate in effect on the date of such Auction.

          5.  Acceptance and Rejection of Submitted Bids and Submitted Sell 
Orders and Allocation of Shares.

          Based on the determinations made pursuant to paragraph (a) of Section 
4 of this Part II, the Submitted Bids and Submitted Sell Orders shall be 
accepted or rejected and the Trust Company shall take such other action as set 
forth below:

          (a)  If Sufficient Clearing Bids have been made, subject to the
     provisions of paragraphs (c), (d) and (e) of this Section 5, Submitted
     Bids and Submitted Sell Orders shall be accepted or rejected as
     follows in the following order of priority and all other Submitted
     Bids shall be rejected:

               (i) the Submitted Sell Orders of Existing Holders shall
          be accepted and the Submitted Bid of each of the Existing
          Holders specifying any rate that is higher than the Winning
          Bid Rate shall be rejected, thus requiring each such
          Existing Holder to sell the shares of Series D Stock that
          are the subject of such Submitted Bid;

               (ii) the Submitted Bid of each of the Existing Holders
          specifying any rate that is lower than the Winning Bid Rate
          shall be accepted, thus entitling each such Existing Holder
          to continue to hold the shares of Series D Stock that are
          the subject of each Submitted Bid;

               (iii) the Submitted Bid of each of the Potential
          Holders specifying any rate that is lower than the Winning
          Bid Rate shall be accepted;

               (iv) the Submitted Bid of each of the Existing Holders 
          specifying a rate that is equal to the Winning Bid Rate
          shall be accepted, thus entitling each such Existing Holder
          to continue to hold the shares of Series D Stock that are
          the subject of such Submitted Bid, unless the number of
          outstanding shares of Series D Stock subject to all such
          Submitted Bids shall be greater than the number of shares of
          Series D Stock ("remaining shares") equal to the excess of
          the Available Series D Stock over the number of shares of
          Series D Stock subject to Submitted Bids described in
          subparagraphs (ii) and (iii) of this paragraph (a), in which
          event the Submitted Bids of each such Existing Holder shall
          be rejected, and each such Existing Holder shall be required
          to sell shares of Series D Stock but only in

                                -57-
<PAGE>
 
          an amount equal to the difference between (A) the number of
          outstanding shares of Series D Stock then held by such
          Existing Holder subject to such Submitted Bid and (B) the
          number of shares of Series D Stock obtained by multiplying
          the number of remaining shares by a fraction the numerator
          of which shall be the number of Outstanding shares of Series
          D Stock held by such Existing Holder subject to such
          Submitted Bid and the denominator of which shall be the sum
          of the number of Outstanding shares of Series D Stock
          subject to such Submitted Bids made by all such Existing
          Holders that specified a rate equal to the Winning Bid Rate;
          and

               (v) the Submitted Bid of each of the Potential Holders
          specifying a rate that is equal to the Winning Bid Rate
          shall be accepted but only in an amount equal to the number
          of shares of Series D Stock obtained by multiplying the
          difference between the Available Series D Stock and the
          number of shares of Series D Stock subject to Submitted Bids
          described in subparagraphs (ii), (iii) and (iv) of this
          paragraph (a) by a fraction the numerator of which shall be
          the number of Outstanding shares of Series D Stock subject
          to such Submitted Bid and the denominator of which shall be
          the sum of the number of outstanding shares of Series D
          Stock subject to such Submitted Bids made by all such
          Potential Holders that specified a rate equal to the Winning
          Bid Rate.

          (b)  If Sufficient Clearing Bids have not been made (other than
     because all of the Outstanding shares of Series D Stock are subject to
     Submitted Hold Orders), subject to the provisions of paragraphs (c),
     (d) and (e) of this Section 5, Submitted Orders shall be accepted or
     rejected as follows in the following order of priority and all other
     Submitted Bids shall be rejected:

               (i) the Submitted Bid of each Existing Holder
          specifying any rate that is equal to or lower than the
          Maximum Rate shall be accepted, thus entitling such Existing
          Holder to continue to hold the shares of Series D Stock that
          are the subject of such Submitted Bid;

               (ii) the Submitted Bid of each Potential Holder
          specifying any rate that is equal to or lower than the
          Maximum Rate shall be accepted; and

               (iii) the Submitted Bids of each Existing Holder
          specifying any rate that is higher than the Maximum Rate
          shall be rejected and the Submitted Sell Orders of each
          Existing Holder shall be accepted, in both cases only in an
          amount equal to the difference between (A) the number of
          Outstanding shares of Series D Stock then held by such
          Existing Holder subject to such Submitted Bid or Submitted
          Sell Order and (B) the number of shares of Series D Stock
          obtained by multiplying the difference between the Available
          Series D Stock and the aggregate number of shares of Series
          D Stock subject to

                                     -58-
<PAGE>
 
     Submitted Bids described in subparagraphs (i) and (ii) of this 
     paragraph (b) by a fraction the numerator of which shall be the 
     number of Outstanding shares of Series D Stock held by such 
     Existing Holder subject to such Submitted Bid or Submitted Sell 
     Order and the denominator of which shall be the number of 
     Outstanding shares of Series D Stock subject to all such 
     Submitted Bids and Submitted Sell Orders.

     (c)  If all of the Outstanding shares of Series D Stock are the subject of 
Submitted Hold Orders, all Submitted Bids shall be rejected.

     (d)  If, as a result of the procedures described in paragraph (a) or (b) of
this Section 5, any Existing Holder would be entitled or required to sell, or
any Potential Holder would be entitled or required to purchase, a fraction of a
share of Series D Stock on any Auction Date, the Trust Company, in such manner
as it shall determine in its sole discretion, shall round up or down the number
of shares of Series D Stock to be purchased or sold by any Existing Holder or
Potential Holder on such Auction Date so that the number of shares purchased or
sold by each Existing Holder or Potential Holder on such Auction Date shall be
whole shares of Series D Stock.

     (e)  If, as a result of the procedures described in paragraph (a) of this 
Section 5, any Potential Holder would be entitled or required to purchase less 
than a whole share of Series D Stock on any Auction Date, the Trust Company, in 
such manner as it shall determine in its sole discretion, shall allocate shares 
for purchase among Potential Holders so that only whole shares of Series D Stock
are purchased on such Auction Date by any Potential Holder, even if such 
allocation results in one or more of such Potential Holders not purchasing 
shares of Series D Stock on such Auction Date.

     (f)  Based on the results of each Auction, the Trust Company shall
determine the aggregate number of shares of Series D Stock to be purchased and
the aggregate number of shares of Series D Stock to be sold by Potential Holders
and Existing Holders on whose behalf each Broker-Dealer submitted Bids or Sell
Orders and, with respect to each Broker-Dealer, to the extent that such
aggregated number of shares to be purchased and such aggregate number of shares
to be sold differ, determine to which other Broker-Dealer or Broker-Dealers
acting for one or more purchasers such Broker-Dealer shall deliver, or from
which other Broker-Dealer or Broker-Dealers acting for one or more sellers such
Broker-Dealer shall receive, as the case may be, shares of Series D Stock.

     6.        Miscellaneous.

     (a)  The Board of Directors may interpret the provisions of this Part II to
resolve any inconsistency or ambiguity which may arise or be revealed in
connection which the Auction Procedures provided for herein, and if such
inconsistency or ambiguity reflects an inaccurate provision hereof, the Board of
Directors may, in

                                     -59-

<PAGE>
 
     appropriate circumstances, authorize the filing of a Certificate of
     Correction or Certificate of Amendment.

          (b)  So long as the Applicable Rate is based on the results of an
     Auction, an Existing Holder (i) may sell, transfer or otherwise dispose of
     shares of Series D Stock only pursuant to a Bid or Sell Order in accordance
     with the procedures described in this Part II or to or through a Broker-
     Dealer or to a Person that has delivered a signed copy of a Purchaser's
     Letter to the Trust Company, provided that in the case of all transfers
     other than pursuant to Auctions such Existing Holder or its Broker-Dealer
     advises the Trust Company of such transfer, and (ii) shall have the
     ownership of the shares of Series D Stock held by it maintained in book
     entry form by the Securities Depository in the account of its Agent Member,
     which in turn will maintain records of such Existing Holder's beneficial
     ownership.

          (c)  Neither the Corporation nor any Affiliate thereof may submit an
     Order in any Auction. Any Broker-Dealer that is an Affiliate of the
     Corporation may not submit Bids to purchase shares of Series D Stock in
     Auctions for its own account, and if such affiliated Broker-Dealer has
     otherwise acquired shares for its own account, it must submit a Sell Order
     in the next Auction with respect to such shares.

          (d)  The Trust Company shall reject any Submitted Order of the
     Corporation or an Affiliate, except for Sell Orders of affiliated Broker-
     Dealers.
     
          (e)  From and after the occurrence of a Rate Adjustment Event, shares
     of Series D Stock shall be registered for transfer or exchange and new
     certificates issued upon surrender of the old certificates deemed by the
     Trust Company (or any other transfer agent or registrar appointed by the
     Corporation) properly endorsed for transfer with all necessary endorsers'
     signatures guaranteed in such manner and form as the Trust Company (or such
     other transfer agent or registrar) may require by a guarantor reasonably
     believed by the Trust Company (or such other transfer agent or registrar)
     to be responsible, accompanied by such assurances as the Trust Company (or
     such other transfer agent or registrar) shall deem necessary or appropriate
     to evidence the genuineness and effectiveness of each necessary endorsement
     and satisfactory evidence of compliance with all applicable laws relating
     to the collection of taxes or funds necessary for the payment of such
     taxes.




(d) 6.25% Cumulative Convertible Preferred Stock, Series E

1.   Designation.

                                     -60-

<PAGE>
 
     The designation of said series of Preferred Stock shall be 6.25% Cumulative
Convertible Preferred Stock, Series E (the "Series E Stock"). The maximum number
of shares of Series E Stock shall be 50,000. The Series E Stock shall be without
par value (stated value of $1,000.00 per share).

2.   Dividends.

     (a)  The Series E Stock shall be entitled to receive dividends at an annual
     rate of $62.50 per share. Such dividends shall accrue and be cumulative
     from the date of original issuance of the Series E Stock and shall be
     payable, when and as declared by the Board, on the 15th day of February,
     May, August and November of each year commencing the 15th day of May 1992.
     Each such dividend shall be paid to the holders of record of the Series E
     Stock as they appear on the stock register of the Corporation at the close
     of business on the applicable record date, which shall be the last day of
     the month preceding the month in which the dividend payment date of such
     dividend occurs, provided that no dividend shall be paid on shares of
     Series E Stock redeemed on a redemption date which is between a dividend
     payment record date and the corresponding dividend payment date (an amount
     equal to such dividend being payable with the redemption price pursuant to
     Section 4(a)). Dividends on account of arrears or any past dividend periods
     may be declared and paid at any time, without reference to any regular
     dividend payment date, to holders of record on such date, not exceeding 45
     days preceding the payment date thereof, as may be fixed by the Board.

     (b) No full dividends shall be declared or paid or set aside for payment on
     Preferred Stock of any series ranking, as to dividends, on a parity with or
     junior to the Series E Stock for any period unless full cumulative
     dividends have been or contemporaneously are declared and paid or declared
     and a sum sufficient for the payment thereof set apart for such payment on
     the Series E Stock for all dividend payment periods terminating on or prior
     to the date of payment of such full cumulative dividends. When dividends
     are not paid in full, as aforesaid, upon the Series E Stock and any other
     Preferred Stock ranking on a parity as to dividends with the Series E
     Stock, all dividends declared upon the Series E Stock and any other
     Preferred Stock ranking on a parity as to dividends with the Series E Stock
     shall be declared pro rata so that the amount of dividends declared per
     share on the Series E Stock and such other Preferred Stock shall in all
     cases bear to each other the same ratio that accrued dividends per share on
     the Series E Stock and such other Preferred Stock bear to each other.
     Holders of Series E Stock shall not be entitled to any dividend, whether
     payable in cash, property or stocks, in excess of the full cumulative
     dividends, as herein provided, on the Series E Stock. No interest, or sum
     of money in lieu of interest, shall be payable in respect of any dividend
     payment on the Series E Stock which may be in arrears.

     (c)  So long as any shares of Series E Stock are outstanding, no dividend
     (other than a dividend in Common Stock or in any other stock ranking junior
     to the Series E Stock as to dividends and upon liquidation and other than
     as provided in paragraph (b) of this Section 2) shall be declared or paid
     or set aside for payment or other distribution declared or made upon the
     Common Stock or upon any other stock ranking junior to or on a parity with
     the Series E Stock as to dividends or

                                     -61- 
<PAGE>
 
     upon liquidation, nor shall any Common Stock or any other stock of the
     Corporation ranking junior to or on a parity with the Series E Stock as to
     dividends or upon liquidation, or any depositary shares representing such
     stock, be redeemed, purchased or otherwise acquired for any consideration
     (or any moneys paid to or made available for a sinking fund or for the
     redemption of any such stock) by the Corporation (except by conversion into
     or exchange for stock of the Corporation ranking junior to the Series E
     Stock as to dividends and upon liquidation) unless, in each case, the full
     cumulative dividends on all outstanding shares of the Series E Stock shall
     have been paid for all past dividend payment periods.

     (d)  Dividends payable on the Series E Stock for any period less than a
     full quarterly dividend period, and for the dividend period beginning on
     the date of issuance of the Series E Stock, shall be computed on the basis
     of a 360-day year consisting of twelve 30-day months.

3.   Voting.


     (a)  Unless the vote or consent of the holders of a greater number of 
     shares shall then be required by law, the consent of the holders of a least
     66-2/3% of all of the shares of the Series E Stock and all other series of
     Preferred Stock ranking on a parity with the Series E Stock, either as to
     dividends or upon liquidation, at the time outstanding, given in person or
     by proxy, either in writing or by a vote at a meeting called for the
     purpose at which the holders of shares of Series E Stock and shares of
     Preferred Stock ranking on a parity with the Series E Stock, either as to
     dividends or upon liquidation, shall vote together as a separate class,
     shall be necessary for authorizing, effecting or validating the amendment,
     alteration or repeal of any of the provisions of this Restated Certificate
     of Incorporation or of any certificate amendatory thereof or supplemental
     thereto (including any Certificate of Designations or any similar document
     relating to the Series E Stock or any series of Preferred Stock ranking on
     a parity with the Series E Stock, either as to dividends or upon
     liquidation) which would adversely affect the powers, preferences, rights
     or privileges of the Series E Stock or the Preferred Stock ranking on a
     parity with the Series E Stock, either as to dividends or upon liquidation;
     provided, however, that if any such amendment, alteration or repeal would
     adversely affect the powers, preferences, rights or privileges of the
     Series E Stock or one or more series of the Preferred Stock ranking on a
     parity with the Series E Stock, either as to dividends or upon liquidation,
     but shall not so affect the entire class, then only the shares of the one
     or more series so affected shall be considered to be a separate class
     entitled to vote upon or consent to such amendment, alteration or repeal;

     (b)  Unless the vote or consent of the holders of a greater number of 
     shares shall then be required by law, the consent of the holders of at
     least 66-2/3% of all of the shares of the Series E Stock and all other
     series of Preferred Stock ranking on a parity with the Series E Stock,
     either as to dividends or upon liquidation, at the time outstanding, given
     in person or by proxy, either in writing or by a vote at a meeting called
     for the purpose at which the holders of shares of the Series E Stock and
     such

                                     -62-

<PAGE>
 
     other series of Preferred Stock ranking on a parity with the Series E
     Stock, either as to dividends or upon liquidation, shall vote together as a
     single class without regard to series, shall be necessary for authorizing,
     effecting or validating the creation, authorization or issue of any shares
     of any class of stock of the Corporation ranking prior to the shares of the
     Series E Stock and such other series of Preferred Stock ranking on a parity
     with the Series E Stock, either as to dividends or upon liquidation, as to
     dividends or upon liquidation, or the reclassification of any authorized
     stock of the Corporation into any such prior shares, or the creation,
     authorization or issue of any obligation or security convertible into or
     evidencing the right to purchase any such prior shares; and

     (c)  If at the time of any annual meeting of stockholders for the election
     of directors a default in preference dividends on the Series E Stock or the
     Preferred Stock ranking on a parity with the Series E Stock, either as to
     dividends or upon liquidation, shall exist, the number of directors
     constituting the Board of Directors shall be increased by two, and the
     holders of the Series E Stock and the Preferred Stock of all series ranking
     on a parity with the Series E Stock, either as to dividends or upon
     liquidation, shall have the right at such meeting, voting together as a
     single class without regard to series, to the exclusion of the holders of
     Common Stock, to elect two directors of the Corporation to fill such newly
     created directorships. Such right shall continue until there are no
     dividends in arrears upon the Series E Stock and the Preferred Stock
     ranking on a parity with the Series E Stock, either as to dividends or upon
     liquidation. Each director elected by the holders of shares of Series E
     Stock and Preferred Stock ranking on a parity with the Series E Stock,
     either as to dividends or upon liquidation, (herein called a "Preferred
     Director") shall continue to serve as such director for the full term for
     which he shall have been elected, notwithstanding that prior to the end of
     such term a default in preference dividends shall cease to exist. Any
     Preferred Director may be removed without cause by, and shall not be
     removed without cause except by, the vote of the holders of record of the
     outstanding shares of Series E Stock and Preferred Stock ranking on a
     parity with the Series E Stock, either as to dividends or upon liquidation,
     voting together as a single class without regard to series, at a meeting of
     the stockholders, or of the holders of shares of Series E Stock and
     Preferred Stock ranking on a parity with the Series E Stock, either as to
     dividends or upon liquidation, called for that purpose. So long as a
     default in preference dividends on the Series E stock or the Preferred
     Stock ranking on a parity with the Series E Stock, either as to dividends
     or upon liquidation, shall exist, (A) any vacancy in the office of
     Preferred Director may be filled (except as provided in the following
     clause (B)) by an instrument in writing signed by the remaining Preferred
     Director and filed with the Corporation and (B) in the case of the removal 
     of any Preferred Director, the vacancy may be filled by the vote of the
     holders of the outstanding shares of Series E Stock and Preferred Stock
     ranking on a parity with the Series E Stock, either as to dividends or upon
     liquidation, voting together as a single class without regard to series, at
     the same meeting at which such removal shall be voted. Each director
     appointed as aforesaid by the remaining Preferred Director shall be deemed,
     for all purposes hereof, to be a Preferred Director. Whenever the term of
     office of the Preferred Directors shall end and a default in preference
     dividends shall no longer exist, the number of directors constituting the
     Board of Directors shall be reduced by two.

                                     -63-
<PAGE>
 
     For the purposes hereof, a "default in preference dividends" on the Series
     E Stock or the Preferred Stock ranking on a parity with the Series E Stock,
     either as to dividends or upon liquidation, shall be deemed to have
     occurred whenever the amount of accrued dividends upon the Series E Stock
     or any series of the Preferred Stock ranking on a parity with the Series E
     Stock, either as to dividends or upon liquidation, shall be equivalent to
     six full quarterly dividends (which, with respect to any Series E Stock or
     any Preferred Stock ranking on a parity with the Series E Stock, either as
     to dividends or upon liquidation, providing for other than quarterly
     dividend periods, shall be deemed to be dividends in respect of a number of
     dividend periods containing not less than 540 days) or more, and, having so
     occurred, such default shall be deemed to exist thereafter until, but only
     until, all accrued dividends on all shares of Series E Stock and Preferred
     Stock ranking on a parity with the Series E Stock, either as to dividends
     or upon liquidation, of each and every series then outstanding shall have
     been paid to the end of the last preceding dividend period.

     (d)  Whenever the holders of the Series E stock shall be entitled to vote
     pursuant to this resolution, such holders shall have one vote for each
     whole share of Series E Stock.

4.   Redemption.

     (a)  The Corporation may, at its option, but only with prior approval of
     the Board of Governors of the Federal Reserve System, redeem the Series E
     Stock, as a whole or in part, at any time or from time to time prior to the
     conversion thereof pursuant to Section 5, at the redemption price indicated
     below if such redemption is during the periods indicated plus, in each
     case, accrued and unpaid dividends thereon through the day preceding the
     date fixed for redemption, whether or not earned or declared:

     provided, however, that the Series E Stock may not be so redeemed prior to 
     February 15, 1995.

     (b)  In the event that fewer than all the outstanding shares of Series E 
     Stock are to be redeemed, the number of shares of Series E Stock to be 
     redeemed shall be

                                     -64-
<PAGE>
 
     determined by the Board and the shares of Series E Stock to be redeemed
     shall be selected by lot or pro rata as may be determined by the Board or
     by any other method as may be determined by the Board in its sole
     discretion to be equitable.

     (c)  In the event the Corporation shall redeem the Series E Stock, notice
     of such redemption shall be given by first class mail, postage prepaid,
     mailed not less than 20 nor more than 60 days prior to the redemption date,
     to each holder of record of the Series E Stock to be redeemed, at such
     holder's address as the same appears on the stock register of the 
     Corporation. Each such notice shall state: (i) the redemption date; (ii) 
     the number of shares of Series E Stock to be redeemed and, if fewer than 
     all the shares of Series E Stock held by such holder are to be redeemed, 
     the number of shares of Series E Stock to be redeemed from such holder; 
     (iii) the redemption price; (iv) the Conversion Price then in effect; (v) 
     the place or places where certificates for such shares of Series E Stock 
     are to be surrendered for payment of the redemption price; and (vi) that 
     dividends on the shares of Series E Stock to be redeemed will cease to 
     accrue on such redemption date.

     (d)  Notice having been mailed as aforesaid, from and after the redemption 
     date (unless default shall be made by the Corporation in providing money 
     for the payment of the redemption price) dividends on the shares of Series 
     E Stock so called for redemption shall cease to accrue, and said shares of 
     Series E Stock shall no longer be deemed to be outstanding, and all rights 
     of the holders thereof as stockholders of the Corporation (except the right
     to receive from the Corporation the redemption price) shall cease. Upon 
     surrender in accordance with said notice of the certificates for any shares
     of Series E Stock so redeemed (properly endorsed or assigned for transfer, 
     if the Board shall so require and the notice shall so state), such shares 
     of Series E Stock shall be redeemed by the Corporation at the redemption 
     price aforesaid. In case fewer than all the shares of Series E Stock 
     represented by any such certificate are redeemed, a new certificate shall 
     be issued representing the unredeemed shares of Series E Stock without cost
     to the holder thereof.

     (e)  Notwithstanding the foregoing provisions of this Section 4, if any 
     dividends on Series E Stock are in arrears, no Series E Stock shall be 
     redeemed unless all outstanding shares of Series E Stock are simultaneously
     redeemed, and the Corporation shall not purchase or otherwise acquire any 
     Series E Stock or any depositary shares representing Series E Stock; 
     provided, however, that the foregoing shall not prevent the purchase or 
     acquisition of Series E Stock or any depositary shares representing Series 
     E Stock (i) upon the conversion of Series E Stock into shares of Common 
     Stock pursuant to Section 5, (ii) in exchange for shares of Common Stock or
     any other class of stock ranking junior to the Series E Stock as to
     dividends or upon liquidation or (iii) pursuant to a purchase or exchange
     offer made on the same terms to holders of all outstanding shares of Series
     E Stock (treating holders of any depositary shares representing Series E 
     Stock as holders of a proportionate number of shares of Series E Stock for 
     these purposes).

5.   Conversion.

                                     -65-
<PAGE>
 
(a)  Subject to the provisions for adjustment hereinafter set forth, each share 
of Series E Stock shall be convertible at the option of the holder thereof, in
the manner hereinafter set forth, into fully paid and nonassessable shares of
Common Stock at the conversion price, determined as hereinafter provided, in
effect on the date of conversion, each share of Series E Stock being credited at
its stated value; provided that if any of the Series E Stock is called for
redemption, the conversion rights pertaining thereto will terminate at the close
of business on the redemption date. The price at which shares of Common Stock
shall be delivered upon conversion of shares of Series E Stock (hereinafter
referred to as the "Conversion Price") shall be initially $62.25 per share of
Common Stock. The Conversion Price shall be adjusted in certain instances as
provided in paragraph (b) of this Section 5.

Any holder of Series E Stock desiring to convert such stock into shares of
Common Stock shall surrender the certificate or certificates for the shares of
Series E Stock being converted, duly endorsed or assigned to the Corporation or
in blank, at the principal office of the Corporation or at a bank or trust
company appointed by the Corporation for that purpose, accompanied by a written
notice of conversion specifying the number of shares of Series E Stock to be
converted and the name or names in which such holder wishes the certificate or
certificates for shares of Common Stock to be issued; in case such notice shall
specify a name or names other than that of such holder, such notice shall be
accompanied by payment of all transfer taxes payable upon the issue of shares of
Common Stock in such name or names. In case less than all of the shares of
Series E Stock represented by a certificate are to be converted by a holder,
upon such conversion the Corporation shall issue and deliver or cause to be
issued and delivered to such holder a certificate or certificates for the shares
of Series E Stock not so converted. The holders of shares of Series E Stock at
the close of business on a dividend payment record date shall be entitled to
receive the dividend payable on such shares of Series E Stock (except shares of
Series E Stock redeemed on a redemption date between such record date and the
dividend payment date) on the corresponding dividend payment date
notwithstanding the subsequent conversion thereof or the Corporation's default
in payment of the dividend due on such dividend payment date. However, shares of
Series E Stock surrendered for conversion during the period from the close of
business on any dividend payment record date for the Series E Stock to the
opening of business on the corresponding dividend payment date (except shares of
Series E Stock called for redemption on a redemption date during such period)
must be accompanied by payment of an amount equal to the dividend payable on
such shares of Series E Stock on such dividend payment date. A holder of shares
of Series E Stock on a dividend payment record date who (or whose transferee)
converts shares of Series E Stock on a dividend payment date will receive the
dividend payable on such shares of Series E Stock by the Corporation on such
date, and the converting holder need not include payment in the amount of such
dividend upon surrender of shares of Series E Stock for conversion. Except as
provided above, no payment or adjustment will be made on account of accrued or
unpaid dividends upon the conversion of Series E Stock.

As promptly as practicable after the surrender of certificates for shares of
Series E Stock as aforesaid, the Corporation shall issue and shall deliver at 
such office to

                                     -66-
<PAGE>
 
such holder, or on his or her written order, a certificate or certificates for 
the number of full shares of Common Stock issuable upon the conversion of such 
shares in accordance with the provisions of this Section (5), and any fractional
interest in respect of a share of Common Stock arising upon such conversion 
shall be promptly settled as provided in paragraph (k) of this Section (5).

Each conversion shall be deemed to have been effected immediately prior to the
close of business on the date on which the certificates for shares of Series E
Stock shall have been surrendered and such notice received by the Corporation as
aforesaid; the shares of Series E Stock so surrendered for conversion shall no
longer be deemed to be outstanding and all rights with respect to such shares of
Series E Stock shall cease, except the right of the holders thereof to receive
full shares of Common Stock in exchange therefor and payment for any fractional
shares; and the person or persons in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become the holder or holders of record of the shares
represented thereby at such time on such date and such conversion shall be at
the Conversion Price in effect at such time on such date. All shares of Common
Stock delivered upon conversions of the Series E Stock will upon delivery be
duly and validly issued and fully paid and nonassessable.

(b)  The Conversion Price shall be adjusted from time to time as follows:

     (i)  In case the Corporation shall pay or make a dividend or other 
     distribution on any class of capital stock of the Corporation in shares of
     Common Stock, the Conversion Price in effect at the opening of business on
     the day following the date fixed for the determination of stockholders
     entitled to receive such dividend or other distribution shall be reduced by
     multiplying such Conversion Price by a fraction of which the numerator
     shall be the number of shares of Common Stock outstanding at the close of
     business on the date fixed for such determination and the denominator shall
     be the sum of such number of shares and the total number of shares
     constituting such dividend or other distribution, such reduction to become
     effective immediately after the opening of business on the day following
     the date fixed for such determination.

     (ii) In case the Corporation shall issue rights or warrants to all holders 
     of its shares of Common Stock entitling them to subscribe for or purchase
     Common Stock at a price per share less than the current market price per
     share (determined as provided in paragraph (c)) of the Common Stock on the
     date fixed for the determination of stockholders entitled to receive such
     rights or warrants, the Conversion Price in effect at the opening of
     business on the day following the date fixed for such determination shall
     be reduced by multiplying such Conversion Price by a fraction of which the
     numerator shall be the number of shares of Common Stock outstanding at the
     close of business on the date fixed for such determination plus the number
     of shares of Common Stock which the aggregate offering price of the total
     number of shares of Common Stock so offered for subscription or purchase
     would
          
                                     -67-
<PAGE>
 
     purchase at such current market price and the denominator shall be the
     number of shares of Common Stock outstanding at the close of business on
     the date fixed for such determination plus the number of shares of Common
     Stock so offered for subscription or purchase, such reduction to become
     effective immediately after the opening of business on the day following
     the date fixed for such determination.

     (iii) In case the Corporation shall, by dividend or otherwise, distribute
     to all holders of shares of Common Stock evidences of indebtedness or
     assets (including securities, but excluding any rights or warrants referred
     to in paragraph (b)(ii), any dividend or distribution paid in cash out of
     the surplus of the Corporation and any dividend or distribution referred to
     in paragraph (b)(i)), the Conversion Price shall be adjusted so that the
     same shall equal the price determined by multiplying the Conversion Price
     in effect immediately prior to the close of business on the date fixed for
     the determination of stockholders entitled to receive such distribution by
     a fraction of which the numerator shall be the current market price per
     share (determined as provided in paragraph (c)) of the Common Stock on the
     date fixed for such determination, less the then fair market value (as
     determined by the Board, whose determination shall be conclusive) of the
     portion of the assets or evidences of indebtedness so distributed allocable
     to one share of Common Stock, and the denominator shall be such current
     market price per share of Common Stock, such adjustment to become effective
     immediately prior to the opening of business on the day following the date
     fixed for the determination of stockholders entitled to receive such
     distribution. Notwithstanding the foregoing, in the event that the
     Corporation shall distribute or shall have distributed any rights or
     warrants to acquire capital stock ("Rights") pursuant to this subparagraph
     (iii), the distribution of separate certificates representing the Rights
     subsequent to their initial distribution (whether or not the initial
     distribution of the Rights shall have occurred prior to the date of the
     issuance of the Series E Stock) shall be deemed to be the distribution of
     the Rights for purposes of this subparagraph (iii); provided that the
     Corporation may, in lieu of making any adjustment pursuant to this
     subparagraph (iii) upon a distribution of separate certificates
     representing the Rights, make proper provision so that each holder of
     Series E Stock who converts such Series E Stock (or any portion thereof)
     (A) before the record date for such distribution of separate certificates
     shall be entitled to receive upon conversion shares of Common Stock issued
     with Rights and (B) after such record date and prior to the expiration,
     redemption or termination of the Rights shall be entitled to receive upon
     conversion, in addition to the shares of Common Stock issuable upon
     conversion, the same number of Rights as would a holder of the number of
     shares of Common Stock that such Series E Stock so converted would have
     entitled the holder thereof to purchase in accordance with the terms and
     provisions applicable to the Rights if such Series E Stock were converted
     immediately prior to the record date for such distribution. Common Stock
     owned by or held for the account of the Corporation or any

                                     -68-
<PAGE>
 
     majority owned subsidiary shall not be deemed outstanding for the purpose 
     of any adjustment required under this subparagraph (iii).

     (iv)  In case the outstanding shares of Common Stock shall be subdivided 
     into a greater number of shares, the Conversion Price in effect at the
     opening of business on the day following the day upon which such
     subdivision becomes effective shall be proportionately reduced, and,
     conversely, in case outstanding shares of Common Stock shall each be
     combined into a smaller number of shares, the Conversion Price in effect at
     the opening of business on the day following the day upon which such
     combination becomes effective shall be proportionately increased, such
     reduction or increase, as the case may be, to become effective immediately
     after the opening of business on the day following the day upon which such
     subdivision or combination becomes effective.

     (v)   The reclassification of Common Stock into securities other than 
     Common Stock (other than any reclassification upon a consolidation or
     merger to which paragraph (f) applies) shall be deemed to involve (i) a
     distribution of such securities other than Common Stock to all holders of
     Common Stock (and the effective date of such reclassification shall be
     deemed to be "the date fixed for the determination of stockholders entitled
     to receive such distribution" and the "date fixed for such determination"
     within the meaning of paragraph (b)(iii)), and (ii) a subdivision or
     combination, as the case may be, of the number of shares of Common Stock
     outstanding immediately prior to such reclassification into the number of
     shares of Common Stock outstanding immediately thereafter (and the
     effective date of such reclassification shall be deemed to be "the day upon
     which such subdivision becomes effective," or "the day upon which such
     combination becomes effective," as the case may be, and "the day upon which
     such subdivision or combination becomes effective" within the meaning of
     paragraph (b)(iv) of this Section 5.

(c)  For the purpose of any computation under paragraphs (b)(ii) and (b)(iii), 
the current market price per share of Common Stock on any day shall be deemed to
be the average of the daily Closing Prices for any 15 consecutive Trading Days 
selected by the Board commencing not less than 20 nor more than 30 Trading Days 
before the day in question.

(d)  Notwithstanding the provisions of paragraphs (b) above, no adjustment in 
the Conversion Price shall be required unless such adjustment (plus any 
adjustments not previously made by reason of this paragraph (d)) would require 
an increase or decrease of at least 1% in such price; provided, however, that 
any adjustments which by reason of this paragraph (d) are not required to be 
made shall be carried forward and taken into account in any subsequent 
adjustment. All calculations under this Section 5 shall be made to the nearest 
cent.

(e)  The Corporation may make such reductions in the Conversion Price, in 
addition to those required by this Section 5, as it considers to be advisable in
order

                                     -69-
<PAGE>
 
to avoid or diminish any income tax to any holder of shares of Common Stock 
resulting from any dividend or distribution of stock or issuance of rights or 
warrants to purchase or subscribe for stock or from any event treated as such 
for income tax purposes or for any other reasons. The Corporation shall have the
power to resolve any ambiguity or correct any error in this Section 5 and its 
actions in so doing shall be final and conclusive.

(f)     In case the Corporation shall effect any capital reorganization of the 
Common Stock (other than a subdivision, combination, capital reorganization or 
reclassification provided for in paragraph (b)) or shall consolidate, merge or 
engage in a statutory share exchange with or into any other corporation (other 
than a consolidation, merger or share exchange in which the Corporation is the 
surviving corporation and each share of Common Stock outstanding immediately 
prior to such consolidation or merger is to remain outstanding immediately after
such consolidation or merger) or shall sell or transfer all or substantially all
its assets to any other corporation, lawful provision shall be made as a part of
the terms of such transaction whereby the holders of Series E Stock shall
receive upon conversion thereof, in lieu of each share of Common Stock which
would have been issuable upon conversion of such stock if converted immediately
prior to the consummation of such transaction, the same kind and amount of stock
(or other securities, cash or property, if any) as may be issuable or
distributable in connection with such transaction with respect to each share of
Common Stock outstanding at the effective time of such transaction, subject to
subsequent adjustments for subsequent stock dividends and distributions,
subdivisions or combinations of shares, capital reorganizations,
reclassifications, consolidations, mergers or share exchanges, as nearly
equivalent as possible to the adjustments provided for in this Section 5.

(g)     Whenever the Conversion Price is adjusted as herein provided:

        (i)  the Corporation shall compute the adjusted Conversion Price and 
        shall cause to be prepared a certificate signed by the chief financial
        or accounting officer of the Corporation setting forth the adjusted
        Conversion Price and showing in reasonable detail the facts upon which
        such adjustment is based and the computation thereof and such
        certificate shall forthwith be filed with each transfer agent for the
        Series E Stock; and

        (ii) a notice stating that the Conversion Price has been adjusted and
        setting forth the adjusted Conversion Price shall, as soon as
        practicable, be mailed to the holders of record of outstanding shares of
        Series E Stock.
        
(h)     In case:

        (i)  the Corporation shall declare a dividend or other distribution on 
        the Common Stock otherwise than in cash out of its surplus;

        (ii) the Corporation shall authorize the granting to the holders of the 
        Common Stock of rights or warrants entitling them to subscribe for or
        purchase any shares of capital stock of any class or of any other
        rights;

                                     -70-
<PAGE>
 
          (iii) of any reclassification of the Common Stock (other than a
          subdivision or combination of outstanding shares of Common Stock), or
          of any consolidation, merger or share exchange to which the
          Corporation is a party and for which approval of any stockholders of 
          the Corporation is required, or of the sale or transfer of all or
          substantially all the assets of the Corporation; or

          (iv) of the voluntary or involuntary liquidation, dissolution or 
          winding up of the Corporation;

     then the Corporation shall cause to be mailed to each transfer agent for
     the Series E Stock and to the holders of record of the outstanding shares
     of Series E Stock, at least 20 days (or 10 days in any case specified in
     paragraphs (i) or (ii) above) prior to the applicable record or effective
     date hereinafter specified, a notice stating (i) the date as of which the
     holders of record of shares of Common Stock to be entitled to such
     dividend, distribution, rights or warrants are be determined, or (ii) the
     date on which such reclassification, consolidation, merger, share exchange,
     sale, transfer, liquidation, dissolution or winding up is expected to
     become effective and the date as of which it is expected that holders of
     record of Common Stock shall be entitled to exchange their shares for
     securities or other property, if any, deliverable upon such
     reclassification, consolidation, merger, share exchange, sale, transfer,
     liquidation, dissolution or winding up. Such notice shall also state
     whether such transaction will result in any adjustment in the Conversion
     Price applicable to the Series E Stock and, if so, shall state what the
     adjusted Conversion Price will be and when it will become effective.
     Neither the failure to give the notice required by this paragraph (h), nor
     any defect therein, to any particular holder shall affect the sufficiency
     of the notice or the legality or validity of the proceedings described in
     paragraphs (h)(i) through (h)(iv).

     (i)  The Corporation shall at all times reserve and keep available out of 
     its authorized but unissued shares of Common Stock, for the purpose of
     issuance upon conversion of Series E Stock, the full number of shares of
     Common Stock then issuable upon the conversion of all shares of Series E
     Stock then outstanding and shall take all action necessary so that shares
     of Common Stock so issued will be validly issued, fully paid and
     nonassessable.

     (j)  The Corporation will pay any and all stamp or similar taxes that may 
     be payable in respect of the issuance or delivery of shares of Common Stock
     on conversion of Series E Stock. The Corporation shall not, however, be
     required to pay any tax which may be payable in respect of any transfer
     involved in the issuance and delivery of shares of Common Stock in a name
     other than that in which the Series E Stock so converted were registered,
     and no such issuance or delivery shall be made unless and until the person
     requesting such issuance has paid to the Corporation the amount of any such
     tax or has established to the satisfaction of the Corporation that such tax
     has been paid.

     (k)  No fractional shares or scrip representing fractional shares of 
     Common Stock shall be issued upon the conversion of Series E Stock. If any
     such conversion would

                                     -71-


<PAGE>
 
     otherwise require the issuance of such a fractional share an amount equal
     to such fraction multiplied by the Closing Price per share of Common Stock
     on the day of conversion shall be paid to the holder in cash by the
     Corporation.

     (l)  The certificate of any independent firm of public accountants of 
     recognized standing selected by the Board shall be presumptive evidence of
     the correctness of any computation made under this Section 5.

6.   Liquidation Rights.

     (a)  Upon the dissolution, liquidation or winding up of the Corporation, 
     the holders of the Series E Stock shall be entitled to receive out of the
     assets of the Corporation, before any payment or distribution shall be made
     on the Common Stock or on any other class of stock ranking junior to the
     Preferred Stock upon liquidation, the amount of $1,000.00 per share, plus a
     sum equal to all dividends (whether or not earned or declared) on such
     shares accrued and unpaid thereon to the date of the final distribution.

     (b)  Neither the sale of all or substantially all the property or business
     of the Corporation, nor the merger or consolidation of the Corporation into
     or with any other corporation or the merger or consolidation of any other
     corporation into or with the Corporation, shall be deemed to be a
     dissolution, liquidation or winding up, voluntary or involuntary, for the
     purposes of this Section 6.

     (c)  After the payment to the holders of the Series E Stock of the full
     preferential amounts provided for in this Section 6, the holders of Series
     E Stock as such shall have no right or claim to any of the remaining assets
     of the Corporation.

     (d)  In the event the assets of the Corporation available for distribution
     to the holders of Series E Stock upon any dissolution, liquidation or
     winding up of the Corporation, whether voluntary or involuntary, shall be
     insufficient to pay in full all amounts to which such holders are entitled
     pursuant to paragraph (a) of this Section 6, no such distribution shall be
     made on account of any shares of any other class or series of Preferred
     Stock ranking on a parity with the Series E Stock upon such dissolution,
     liquidation or winding up unless proportionate distributive amounts shall
     be paid on account of the Series E Stock, ratably, in proportion to the
     full distributable amounts for which holders of all such parity shares are
     respectively entitled upon such dissolution, liquidation or winding up.
     
     (e)  Upon the dissolution, liquidation or winding up of the Corporation,
     the holders of shares of Series E Stock then outstanding shall be entitled
     to be paid out of the assets of the Corporation available for distribution
     to its stockholders all amounts to which such holders are entitled pursuant
     to paragraph (a) of this Section 6 before any payment shall be made to the
     holders of any class or series of capital stock of the Corporation ranking
     junior upon liquidation to the Series E Stock.

7.   Sinking or Retirement Fund.

                                      72
<PAGE>
 
     The Series E Stock shall not be entitled to the benefit of a sinking or
retirement fund to be applied to the purchase or redemption of such stock.

8.   Rank.
 
     For purposes of this resolution, any stock of any class or classes of the
Corporation shall be deemed to rank:

     (a)  prior to the Series E Stock, either as to dividends or upon
     liquidation, if the holders of such class or classes shall be entitled to
     the receipt of dividends or of amounts distributable upon dissolution,
     liquidation or winding up of the Corporation, as the case may be, in 
     preference or priority to the holders of Series E Stock;

     (b)  on a parity with the Series E Stock, either as to dividends or upon 
     liquidation, whether or not the dividend rates, dividend payment dates or
     redemption or liquidation prices per share or sinking fund provisions, if
     any, are different from those of the Series E Stock, if such stock is the
     Corporation's Auction Preferred Stock, Series C, or Flexible Auction
     Preferred Stock, Series D, or if the holders of such stock shall be
     entitled to the receipt of dividends or of amounts distributable upon
     dissolution, liquidation or winding up of the Corporation, as the case may
     be, in proportion to their respective dividend rates or liquidation prices,
     without preference or priority, one over the other, as between the holders
     of such stock and the holders of Series E Stock; and

     (c)  junior to the Series E Stock, either as to dividends or upon 
     liquidation, if such class shall be the Corporation's Series A Junior 
     Participating Preferred Stock, Common Stock or if the holders of Series E 
     Stock shall be entitled to receipt of dividends or of amounts distributable
     upon dissolution, liquidation or winding up of the Corporation, as the case
     may be, in preference or priority to the holders of shares of such class or
     classes.

                                 Common Stock

1.   Dividends.

     Subject to the preferential rights of the Preferred Stock, the holders of 
the Common Stock are entitled to receive, to the extent permitted by law, such 
dividends as may be declared from time to time by the Board of Directors.

2.   Liquidation.

     In the event of the voluntary or involuntary liquidation, dissolution,
distribution of assets or winding up of the Corporation, after distribution in
full of the preferential amounts, if any, to be distributed to the holders of
shares of Preferred Stock, holders of Common Stock shall be entitled to receive
all of the remaining assets of the Corporation of whatever kind available for
distribution to stockholders ratably in proportion to the number of shares of
Common Stock held by them respectively. The Board of Directors may distribute in
kind to the holders of Common Stock such remaining assets of the Corporation or
may sell, transfer or otherwise dispose of all or any part of such remaining
assets to any other corporation, trust or other entity and receive payment
therefor in cash, stock or obligations of such other corporation, trust or other
entity, or any combination thereof, and may sell all or any part of the
consideration so received and distribute any balance thereof in kind to holders
of Common Stock. The merger or consolidation of the Corporation into or with any
other corporation, or the merger of any other corporation into it, or any
purchase or redemption of shares of stock of the Corporation of any class, shall
not be deemed to be a dissolution, liquidation or winding up of the Corporation
for the purposes of this paragraph.

3.   Voting Rights.

     Except as may be otherwise required by law or this Restated Certificate of 
Incorporation, each holder of Common Stock has one vote in respect of each share
of stock held by him of record on the books of the Corporation on all matters 
voted upon by the Stockholders.

                                      III
 
                               Other Provisions

1.   Preemptive Rights.
 
     No stockholder shall have any preemptive right to subscribe to an
additional issue of stock of any class or series or to any securities of the
Corporation convertible into such stock.

2.   Changes in Authorized Capital Stock.

     Subject to the protective conditions and restrictions of any outstanding 
Preferred Stock, any amendment to this Restated Certificate of Incorporation 
which increases or decreases the authorized capital stock of any class or
classes may be adopted by the affirmative vote of the holders of a majority of
the outstanding shares of the voting stock of the Corporation.

                              Board of Directors

1.   Powers of the Board.

     In furtherance and not in limitation of the powers conferred by statute, 
the Board of Directors is expressly authorized:

          (a)  To make, alter or repeal the by-laws of the Corporation.

          (b)  To authorize and cause to be executed mortgages and liens upon 
     the real and personal property of the Corporation.

          (c)  To set apart out of any of the funds of the Corporation available
     for dividends a reserve or reserves for any proper purpose and to abolish
     any reserve in the manner in which it was created.

          (d)  By a majority of the whole board, to designate one or more 
     committees, each committee to consist of one or more of the directors of
     the Corporation. The Board may designate one or more directors as alternate
     members of any committee, who may replace any absent or disqualified member
     at any meeting of the committee. The by-laws may provide that in the
     absence or disqualification of a member of a committee, the member or
     members thereof present at any meeting and not disqualified from voting,
     whether or not he or they constitute a quorum, may unanimously appoint
     another member of the Board of Directors to act at the meeting in the place
     of any such absent or disqualified member. Any such committee, to the
     extent provided in the resolution of the Board of Directors, or in the by-
     laws of the Corporation, shall have and may exercise all the powers and
     authority of the Board of Directors in the management of the business and
     affairs of the Corporation and may authorize the seal of the Corporation to
     be affixed to all papers which may require it; but no such committee shall
     have the power or authority in reference to amending the Restated
     Certificate of Incorporation, adopting an agreement of merger or
     consolidation, recommending to the stockholders the sale, lease or exchange
     of all or substantially all of the Corporation's property and assets,
     recommending to the stockholders a dissolution of the Corporation or a
     revocation of a dissolution, or amending the by-laws of the Corporation;
     and, unless the resolution or by-laws expressly so provide, no such
     committee shall have the power or authority to declare a dividend or to
     authorize the issuance of stock.

          (e)  When and as authorized by the stockholders in accordance with 
     statute, to sell, lease or exchange all or substantially all of the
     property and assets of the Corporation, including its good will and its
     corporate franchises, upon such terms and conditions and for such
     consideration, which may consist in whole or in part of money or property
     including shares of stock in, and/or other securities of, any other
     corporation or corporations, as the Board of Directors shall deem expedient
     and for the best interests of the Corporation.

2.   Terms and Number of Board Members.

                                     -75-

<PAGE>
 
     The number of members of the Board of Directors will be fixed from time to 
time by the Board of Directors, but (subject to vacancies) in no event may there
be less than three directors. Each director shall serve until the next annual 
meeting of stockholders or until his successor is elected.

     If any vacancy occurs in the Board of Directors during a term, the 
remaining directors, by affirmative vote of a majority thereof, may elect a 
director to fill the vacancy until the next annual meeting of stockholders.

3.   Cumulative Voting.

     At all elections of directors of the Corporation, each stockholder entitled
generally to vote for the election of directors shall be entitled to as many
votes as shall equal the number of votes which (except for this provision as to
cumulative voting) he would be entitled to cast for the election of directors
with respect to his shares of stock multiplied by the number of directors to be
elected, and he may cast all of such votes for a single director or may
distribute them among the number to be voted for, or for any two or more of them
as he may see fit.

                                 ARTICLE SIXTH

                                    Records

     The books of the Corporation may be kept (subject to any provisions 
contained in the statutes) outside the State of Delaware at such place or places
as may be designated from time to time by the Board of Directors or in the 
by-laws of the Corporation. Elections of directors need not be by written ballot
unless the by-laws of the Corporation shall so provide.

                                ARTICLE SEVENTH

                               Certain Contracts

     No contract or transaction between the Corporation and one or more of its 
directors or officers, or between the Corporation and any other corporation, 
partnership, association, or other organization in which one or more of its 
directors or officers are directors or officers, or have a financial interest, 
shall be void or voidable solely for this reason, or solely because the director
or officer is present at or participates in the meeting of the board or 
committee thereof which authorizes the contract or transaction, or solely 
because his or their votes are counted for such purpose, if:

          1.   The material facts as to his interest and as to the contract or 
     transaction are disclosed or are known to the Board of Directors or the
     committee, and the Board of Directors or committee in good faith authorizes
     the contract or transaction by a vote sufficient for such purpose without
     counting the vote of the interested director or directors: or

          2.   The material facts as to his interest and as to the contract or 
     transaction are disclosed or are known to the stockholders entitled to vote
     thereon, and the contract or transaction is specifically approved in good
     faith by vote of the stockholders: or

                                     -76-
<PAGE>
 
          3.  The contract or transaction is fair as to the Corporation as of 
     the time it is authorized, approved or ratified, by the Board of Directors,
     a committee thereof, or the stockholders.

Interested directors may be counted in determining the presence of a quorum at a
meeting of the Board of Directors or of a committee which authorizes the 
contract or transaction.

                                ARTICLE EIGHTH

                                Indemnification

1.   Claim Brought by Third Parties.

     The Corporation shall indemnify any person who was or is a party or is 
threatened to be made a party to any threatened, pending or completed action, 
suit or proceeding, whether civil, criminal, administrative or investigative 
(other than an action by or in the right of the Corporation) by reason of the 
fact that he is or was or has agreed to become a director or officer of the 
Corporation, or is or was serving or has agreed to serve at the request of the 
Corporation as a director or officer of another corporation, partnership, joint 
venture, trust or other enterprise, or by reason of any action alleged to have 
been taken or omitted by such person in such capacity, against costs, charges 
and other expenses (including attorneys' fees) ("Expenses"), judgments, fines 
and amounts paid in settlement actually and reasonably incurred by him in 
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no 
reasonable cause to believe his conduct was unlawful. The termination of any 
action, suit or proceeding by judgment, order, settlement, conviction, or upon 
a plea of nolo contendere or its equivalent, shall not, of itself, create a 
presumption that the person did not act in good faith and in a manner which he 
reasonably believed to be in or not opposed to the best interests of the 
Corporation, and, with respect to any criminal action or proceeding, had 
reasonable cause to believe that his conduct was unlawful.

2.   Claim By or in the Right of the Corporation.

     The Corporation shall indemnify any person who was or is a party or is 
threatened to be made a party to any threatened, pending or completed action or 
suit by or in the right of the Corporation to procure a judgement in its favor 
by reason of the fact that he is or was or has agreed to become a director or 
officer of the Corporation, or is or was serving or has agreed to serve at the 
request of the Corporation as a director or officer of another corporation, 
partnership, joint venture, trust or other enterprise, or by reason of any 
action alleged to have been taken or omitted by such person in such capacity, 
against Expenses actually and reasonably incurred by him in connection with the 
investigation, defense or settlement of such action or suit if he acted in good 
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Corporation and except that no indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the 
Court of Chancery of the State of Delaware or the court in which such action or 
suit was brought shall determine upon application that despite the adjudication 
of liability

                                     -77-

<PAGE>
 
but in view of all the circumstances of the case, such person is fairly and 
reasonably entitled to indemnity for such Expenses which the Court of Chancery 
of the State of Delaware or such other court shall deem proper.

3.   Additional Indemnification.

     In addition to the indemnification provided for in paragraphs 1 and 2 of 
this Article Eighth, the Corporation shall indemnify any person who was or is a 
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of another corporation, partnership,
joint venture, trust or other enterprise by reason of the fact that he is or was
serving or has agreed to serve at the request of the Corporation as a director
of such other corporation, partnership, joint venture, trust or other enterprise
against Expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding
for breach of fiduciary duty as such director, except for liability: (i) for
breach of the duty of loyalty to such other corporation, partnership, joint
venture, trust or other enterprise; (ii) for acts or omissions not in good faith
or which involve intentional misconduct or knowing violation of law; (iii) for
unlawful payment of a dividend or unlawful purchase or redemption of stock; or
(iv) for any transaction from which the director derived an improper personal
benefit.

4.   Successful Defense.

     To the extent that any person referred to in paragraphs 1, 2 or 3 of this 
Article Eighth has been successful on the merits or otherwise, including, 
without limitation, the dismissal of an action without prejudice, in defense of 
any action, suit or proceeding referred to therein or in defense of any claim, 
issue or matter therein, he shall be indemnified against Expenses actually and 
reasonably incurred by him in connection therewith.

5.   Determination of Conduct.

     Any indemnification under paragraphs 1, 2 or 3 of this Article Eighth 
(unless ordered by a court) shall be made by the Corporation only as authorized 
in the specific case upon a determination that indemnification of the director 
or officer is proper in the circumstances because he has met the applicable 
standard of conduct set forth in said paragraphs 1, 2 or 3 of this Article 
Eighth. Such determination shall be made (a) by the board of directors by a 
majority vote of a quorum consisting of directors who were not parties to such 
action, suit or proceeding, or (b) if such quorum is not obtainable, or, even if
obtainable and a quorum of disinterested directors so directs, by independent 
legal counsel in a written opinion, or (c) by the stockholders.

6.   Advance Payment.

     Expenses incurred by any person referred to in paragraphs 1, 2 or 3 of this
Article Eighth in defending a civil or criminal action, suit or proceeding shall
be paid by the Corporation in advance of the final disposition of such action,
suit or proceeding upon receipt of an undertaking by or on behalf of such person
to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation as provided in this Article
Eighth.

7.   Certificate of Incorporation Article Not Exclusive; Change in Law.

                                     -78-
<PAGE>
 
     The indemnification and advancement of Expenses provided by, or granted 
pursuant to, this Article Eighth shall not be deemed exclusive of any other 
rights to which those seeking indemnification or advancement of Expenses may be 
entitled under any law (common or statutory), by-law, agreement, vote of 
stockholders or disinterested directors, or otherwise, both as to action in his 
official capacity and as to action in another capacity while holding such 
office, and shall continue as to a person who has ceased to be a director or 
officer and shall inure to the benefit of the heirs, executors and 
administrators of such a person. Notwithstanding the provisions of this Article 
Eighth, the Corporation shall indemnify and make advancement of Expenses to any 
person referred to in paragraphs 1, 2 or 3 of this Article Eighth to the
fullest extent permitted under the laws of the State of Delaware and any other
applicable laws, as they now exist or as they may be amended in the future.

8.   Contract Rights.

     All rights to indemnification and advancement of Expenses provided by this 
Article Eighth shall be deemed to be a contract between the Corporation and each
person referred to in paragraphs 1, 2 or 3 of this Article Eighth. Any repeal or
modification of this Article Eighth or any repeal or modification of relevant
provisions of the Delaware General Corporation Law or any other applicable law
shall not in any way diminish any rights to indemnification or advancement of
Expenses with respect to any state of facts then or previously existing or any
action, suit or proceeding previously or thereafter brought or threatened based
in whole or in part on such state of facts.

9.   Insurance.

     The Corporation shall have power to purchase and maintain insurance on 
behalf of any person referred to in paragraphs 1, 2 or 3 of this Article Eighth 
against any liability asserted against him and incurred by him in any such 
capacity, or arising out of his status as such, whether or not the Corporation 
would have the power to indemnify him against such liability under the 
provisions of this Article Eighth or of Section 145 of the Delaware General 
Corporation Law.

10.  Indemnification of Employees or Agents.

     The Board of Directors may, by resolution, extend the indemnification and 
advancement of Expenses provisions of this Article Eighth to any person who was 
or is a party or is threatened to be made a party to any threatened, pending or 
completed action, suit or proceeding by reason of the fact that he is or was or 
has agreed to become an employee or agent of the Corporation, or is or was 
serving or has agreed to serve at the request of the Corporation as an employee 
or agent of another corporation, partnership, joint venture, trust or other 
enterprise.

11.  Definition of Corporation.

     For purposes of this Article Eighth, references to the "Corporation" shall 
include, in addition to the resulting corporation, any constituent corporation 
(including any constituent of a constituent) absorbed in a consolidation or 
merger which, if its separate existence had continued, would have had power and 
authority to indemnify its directors, officers, employees or agents so that any 
person who is or was or has agreed to become a director, officer, employee or 
agent of such constituent corporation, or is or was serving or has agreed to 
serve at the request of such constituent

                                     -79-
<PAGE>
 
corporation as a director, officer, employee or agent of another corporation, 
partnership, joint venture, trust or other enterprise, shall stand in the same 
position under the provisions of this Article Eighth with respect to the 
resulting or surviving corporation as he would have with respect to such 
constituent corporation if its separate existence had continued.

12.  Employee Benefit Plans.

     For purposes of this Article Eighth, references to "other enterprises" 
shall include employee benefit plans; references to "fines" shall include any 
excise taxes assessed on a person with respect to an employee benefit plan; and 
references to "serving at the request of the Corporation" shall include any 
service as a director or officer of the Corporation which imposes duties on, or 
involves services by, such director or officer with respect to an employee 
benefit plan, its participants, or beneficiaries; and a person who acted in good
faith and in a manner he reasonably believed to be in the interest of the 
participants and beneficiaries of an employee benefit plan shall be deemed to 
have acted in a manner "not opposed to the best interest of the Corporation" as 
referred to in this Article Eighth.

                                 ARTICLE NINTH

                         Stockholder Action by Consent

     Any corporate action upon which a vote of stockholders is required or
permitted may be taken without a meeting or vote of stockholders with the
written consent of stockholders having not less than a majority of all of the
stock entitled to vote upon the action if a meeting were held; provided, that in
no case shall the written consent be by holders having less than the minimum
percent of the vote required by statute for the proposed corporate action and
provided that prompt notice be given to all stockholders of the taking of
corporate action without a meeting and by less than unanimous written consent.

                                 ARTICLE TENTH

                                   Amendment

     per share."

     (7)  The Capital of the Corporation will not be reduced under or by

     WHEREAS the Company and First Chicago NBD Corporation ("FCNBD") entered
into an Agreement dated October 3, 1996 (the "Agreement") pursuant to which
FCNBD named the Company as the preferred provider for certain of FCNBD's master
trust and institutional custody customers which FCNBD will no longer service;
and

     WHEREAS, in connection with the Agreement, the Company wishes to hire
certain employees of FCNBD and of banks affiliated with FCNBD ("FCNBD Banks") to
assist with servicing former FCNBD customers who become customers of the Company
(each such employee who is hired by the Company pursuant to Section 4.01 of the
Agreement being referred to herein as an "FCNBD Employee"); and

     WHEREAS, it is now deemed desirable to provide for the manner in which the
FCNBD Employees will be treated for purposes of certain welfare and retirement
plans maintained by The Northern Trust Company;

     NOW, THEREFORE, BE IT RESOLVED, that The Northern Trust Company Pension

effective September 30, 1996, to provide that an FCNBD Employee's service with

Vesting Service under those retirement plans (but not for purposes of
determining Credited Service under the Pension Plan, which shall be calculated
based on the FCNBD Employee's date of hire with the Company).

     FURTHER RESOLVED, that for purposes of determining eligibility to
participate and receive benefits under Northern's short- and long-term
disability plans, an FCNBD Employee shall receive credit for his or her prior
employment with FCNBD or an FCNBD Bank (and any predecessor of FCNBD or an FCNBD
Bank) as if such FCNBD Employee had then been employed by the Company.

     FURTHER RESOLVED, that the foregoing resolutions shall apply only with
respect to former employees of FCNBD and FCNBD Banks (or any predecessors of
FCNBD or an FCNBD Bank) who are hired by the Company pursuant to Section 4.01 of
the Agreement, and do not entitle such employees to receive benefits for periods
prior to employment with Northern under any welfare or retirement plan
maintained by The Northern Trust Company, except as expressly provided herein.

          A.   Long-Term Options. Provided that Tenant has previously exercised 
both of the ten (10) year extension options granted under Paragraph 7 above, and
that as of the 11th Floor 5-Year Space Expiration Date, as extended (i.e., 
August 31, 2002), and the 11th Floor 3-Year Space Expiration Date, as extended 
(i.e., August 31, 2002), and at the time that each option described below is

Tenant the option to extend the 11th Floor 5-Year Space Term and the 11th Floor
3-Year Space Term in respect to all (and not less than all) of the 11th Floor 
5-Year Space and 11th Floor 3-Year Space upon the terms, covenants, conditions 
and provisions contained in the Lease and herein (except that (i) Rent will be 
as set forth in the following sentence, (ii) no additional construction 
allowance will be paid by Landlord and (iii) no additional options to extend 
will be created by the exercise of any such option to extend, for two (2) 
separate, successive periods of ten (10) years each, to follow consecutively
upon the 11th Floor 5-Year Space Expiration Date and 11th Floor 3-year Space

11th Floor 3-Year Space Term, respectively, shall expire on the Long-Term Space
Expiration Date as extended pursuant to each of the two (2) respective ten (10)
year extension options granted under Paragraph 27.B. of the Lease. The Rent for
any Lease Year within such extension period shall be calculated on the basis of
the prevailing rental rate(s) (as defined in Paragraph 27.B(ii) of the Lease),

than the Annual Base Rent for the 11th Floor 5-Year Space and 11th Floor 3-Year
Space, respectively, as adjusted, for the fifteenth (15th) Lease Year (in the
case of the first extension option) or the last Lease Year of the first ten (10)
year extension term granted under this Paragraph 8.A. (in the case of the second
extension term). Each such option shall be exercisable by Tenant's giving
written notice (which shall be irrevocable) to Landlord of its exercise of same
not less than one (1) year prior to the expiration date of the then current 11th
Floor 5-Year Space Term and 11th Floor 3-Year Space Term. The option to extend
for the second ten-year extension period granted under this Paragraph 8.A. shall
be conditioned upon Tenant's having exercised the option to extend the 11th
Floor 5-Year Space Term and 11th Floor 3-Year Space Term for the first ten-year
extension period.

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
- --------------------------------------------------------------------------------

Northern Trust Corporation (Corporation) is a bank holding company organized in
1971 to hold all of the outstanding capital stock of The Northern Trust Company
(Bank), an Illinois banking corporation with its headquarters located in the
Chicago financial district. The Corporation also owns banks in Arizona,
California, Florida and Texas, and various other nonbank subsidiaries,
including a securities brokerage firm, a futures commission merchant, an
international investment consulting firm and a retirement services company. The
Corporation also owned three other Illinois banks which were merged into the
Bank on February 29, 1996. Although the operations of other subsidiaries will
be of increasing significance, it is expected that the Bank will continue to be
the major source of the consolidated assets, revenues and net income in the
foreseeable future.
 All references to Northern Trust refer to Northern Trust Corporation and its
subsidiaries on a consolidated basis.
 The Management's Discussion and Analysis of Financial Condition and Results of
Operations should be read in conjunction with Northern Trust's Consolidated
Financial Statements and Consolidated Financial Statistics included herein.
 
RESULTS OF OPERATIONS

OVERVIEW. Net income for 1996 totaled a record $258.8 million, a 17.6% increase
from the $220.0 million earned in 1995 which in turn was 20.8% greater than the
$182.2 million earned in 1994. Fully diluted net income per common share,
reflecting the two-for-one stock split in December, 1996, increased 19% to
$2.20 in 1996, compared with net income per common share of $1.85 in 1995 and
$1.58 in 1994. Over the past five years the compound growth rate in earnings
per share has been 14%.
 The record 1996 net income performance, together with strong growth in equity,
produced a return on average common stockholders' equity of 18.6% compared with
17.6% in 1995 and 16.6% in 1994. The return on average assets was 1.23% in 1996
compared with 1.13% in 1995 and 1.02% in 1994.
 1996 marks the ninth consecutive year of record earnings. Trust fees, net
interest income, foreign exchange profits and treasury management fees were all
at record levels, while trust assets under administration reached $778.9
billion at December 31, 1996, up $165.0 billion from a year ago. Excellent
growth in all of Northern Trust's diversified revenue sources produced a 12%
increase in revenues while operating expenses increased by 8%.
 Primarily through the retention of earnings, offset in part by the repurchase
of common stock pursuant to the Corporation's share buyback program,
stockholders' equity grew to $1.54 billion, as compared to $1.45 billion at
December 31, 1995 and $1.28 billion at December 31, 1994.
 The Board of Directors increased the quarterly dividend per common share 16.1%
in November 1996, to $.18 from $.16, for a new annual rate of $.72. This is the
tenth consecutive year in which the dividend rate has been increased. The
Board's action reflects a policy of increasing the dividend rate with increased
profitability while retaining sufficient earnings to allow for strategic
expansion and the maintenance of a strong balance sheet.

Northern Trust Corporation
<PAGE>
 
 Northern Trust's strategy will continue to focus on growing its two sharply
defined businesses: Corporate and Institutional Services (C&IS) and Personal
Financial Services (PFS). C&IS focuses on administering and managing domestic
and global investment pools for corporate and institutional clients worldwide.
PFS provides financial services to individuals and closely held businesses
through a unique five-state personal financial services franchise. In executing
this strategy, Northern Trust emphasizes service quality through a high level
of personal service and maximization of benefits derived from technology
investments. Expense growth and capital expenditures are closely monitored to
ensure that short- and long-term business strategies and performance objectives
are effectively balanced.
 
NONINTEREST INCOME. The success of Northern Trust's strategy of maintaining a
diverse, fee-oriented revenue base is evidenced by the fact that noninterest
income represented 65% of its total taxable equivalent revenue in 1996,
compared with 63% one year ago. Noninterest income totaled $777.9 million in
1996, $678.1 million in 1995 and $633.4 million in 1994 which included the
$28.5 million pretax gain on the sale of the Corporation's 21% interest in
Banque Scandinave en Suisse (BSS).
 TRUST FEES. Trust fees accounted for 76% of total noninterest income and 49%
of total taxable equivalent revenue in 1996. Trust fees for 1996 increased 17%
to $592.3 million from $505.0 million in 1995 which was up 11% from $453.4
million in 1994. Trust fees have increased at a compound growth rate of 14% for
the last five years. The increase in 1996 trust fees is principally the result
of growth in business from new and existing clients, coupled with strong growth
in stock and bond markets. Fees generated by Northern Trust Global Advisors,
Inc. (NTGA), formerly RCB International Inc., an asset management subsidiary
acquired on October 31, 1995, and The Beach Bank of Vero Beach, Florida (Beach
Bank), a March 31, 1995 acquisition, contributed approximately $22.4 million of
the trust fee growth in 1996. Contributing to the 1995 fee growth were new
business results and higher stock and bond market values, as well as the
incremental impact of fees contributed by NTGA, Beach Bank and Hazlehurst &
Associates (acquired April 1994 and renamed Northern Trust Retirement
Consulting, Inc.). Total trust assets under administration at December 31, 1996
were $778.9 billion compared to $613.9 billion a year ago, an increase of 27%.
Trust assets under management, included in the above, increased 23% to $130.3
billion, from $105.5 billion at the end of 1995.
 Fees are based on the market value of assets managed and administered, the
volume of transactions and securities lending activity, and fees for other
services rendered. Asset-based fees are typically determined on a sliding scale
so that as the value of a client portfolio grows in size, Northern Trust
receives a smaller percentage of the increasing value as fee income. Therefore,
market value or other incremental changes in a portfolio's size do not
typically have a proportionate impact on the level of trust fees. In addition
to fees, certain trust-related activities result in deposits, primarily
interest-bearing, which are maintained with the bank subsidiaries and foreign
branches. These deposits averaged $4.3 billion in 1996 and $4.2 billion in
1995.
 Northern Trust's fiduciary business encompasses Master Trust, Master Custody,
investment management and retirement services for corporate and institutional
asset pools, as well as a complete range of estate planning, fiduciary, and
asset management services for individuals. Fees from these highly focused
services are fairly evenly distributed between Northern Trust's two business
units, C&IS and PFS. The discussion of trust activities in each of these
business units follows.
 CORPORATE AND INSTITUTIONAL SERVICES. Northern Trust is a leading provider of
Master Trust and Master Custody services to retirement plans and institutional
and international clients. In addition to Master Trust and Master Custody, C&IS
offers a comprehensive array of retirement consulting and recordkeeping
services and investment products. At December 31, 1996 trust assets under
administration in C&IS totaled $693.7 billion, an increase of 27% from $544.3
billion a year ago. Trust fees in C&IS increased 22% in 1996 to $298.3 million
from $244.2 million in 1995 which was up 13% from $216.7 million in 1994.
Excluding the incremental fee growth resulting from the NTGA acquisition, C&IS
trust fees in 1996 increased 13% from the prior year. The increase in C&IS
trust fees reflects record net new business and strong securities lending
revenue, moderated by the effect of changing pricing structures for client
relationships which focus on total client revenues. These client relationships
increasingly involve services such as foreign exchange which generate revenues
not reflected in trust fees.
 Retirement Plans. Trust fees from the retirement plans market segment, which
includes the large U.S. corporate market and public and union retirement funds,
totaled $176.4 million in 1996. Trust fees for this segment in 1995 and 1994
totaled $156.4 million and $139.9 million, respectively. Assets under
administration totaled $375.2 billion at December 31, 1996 compared with $304.0
billion a year ago. Growth in this area has been driven by record new business
from both new and existing clients. U.S. demographic trends are expected to
advance the growth of retirement services in future years. Much of the
anticipated growth in retirement assets is expected to come from defined
contribution plans of U.S. corporations. Northern believes that it is well-
positioned to benefit from this trend given its long-term relationships with
corporate sponsors, its family of institutional mutual funds, and recordkeeping
services offered through Northern Trust Retirement Consulting, Inc. (NTRC). The
services offered through
 
                                                                              19

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
- --------------------------------------------------------------------------------

NTRC include retirement plan design, participant recordkeeping, and actuarial
and consulting services that complement Northern Trust's custody, fiduciary and
investment management capabilities in the strategically important retirement
services market.
 Institutional. This market segment, which includes insurance companies,
foundations and endowments, and correspondent trust services, provides
attractive growth opportunities for trust and banking services. The insurance
industry continues to consolidate its relationships with providers who can meet
its full range of banking and custody needs. Northern Trust seeks to maintain
an array of products and services, a strong capital position and systems
capabilities that position it to increase its share of this market. Northern
Trust leverages its investment in technology by providing smaller bank trust
departments with custody, systems, and investment services through its
correspondent trust services offerings. Trust fees from the institutional
market segment in 1996, 1995 and 1994 totaled $53.2 million, $50.1 million and
$48.0 million, respectively. Assets under administration at December 31, 1996
increased to $164.2 billion from $141.6 billion at December 31, 1995.
 International. This segment is composed of non-U.S. clients and group trusts.
When compared to the other C&IS market segments, International has had the
highest compound growth rate for the last four years measured in terms of
assets under administration and trust fees. At December 31, 1996 assets under
administration totaled $111.1 billion, up 65% from $67.3 billion at year-end
1995, which in turn was up 40% over the previous year-end. Trust fees for 1996
increased 27% to $43.0 million. This compares with $33.9 million in 1995 which
was up 18% from $28.8 million in 1994. In October, 1996, Northern Trust
expanded on its global presence by opening a full service office in Singapore.
This office complements Northern Trust's securities lending and investment
management services in Hong Kong, broadening its regional capabilities.
 Global Investment Services. Investment management, securities lending, and
risk and performance analysis services are offered to C&IS clients. Fees
associated with these activities, with the exception of NTGA-related fees, are
included within the market segments above. Total assets under management grew
from $64.4 billion at year-end 1995 to $80.4 billion at year-end 1996; $37.2
billion was associated with direct asset management, including sweep and custom
cash funds, while the remaining $43.2 billion represented securities lending
collateral. In 1996 Northern Trust accelerated its positioning as a global,
multi-asset class manager with an expanded array of investment service and
product capabilities. For example, Northern Trust has expanded its investment
advisory service offerings to offshore clients through a new Dublin subsidiary,
Northern Trust Fund Managers (Ireland) Limited.
 Northern Trust completed its acquisition of NTGA in the fourth quarter of
1995. NTGA provides specialized U.S. and international multiple manager
programs to complement the capabilities of Northern Trust in the fixed income,
equity and short-term markets. Total assets under management at NTGA at
December 31, 1996 were $5.7 billion versus $5.0 billion at year-end 1995. NTGA
earned $25.7 million in trust fees in 1996.
 Clients who utilize trust services may elect to have their securities lent to
generate revenues, thereby improving their portfolio's total return. The cash
that has been deposited by investment firms as collateral for securities they
have borrowed from trust clients under the lending program is managed by
Northern Trust and included in trust assets under management. The growth in
domestic and international securities lending fees, up 49% over 1995, which in
turn was up 19% over 1994, was due primarily to an increase in the volume of
securities loaned. The cash collateral totaled $43.2 billion and $31.4 billion
at December 31, 1996 and 1995, respectively. During the first quarter of 1995,
Northern Trust commenced operations at its new Hong Kong subsidiary to better
facilitate the lending of securities from its clients' global portfolios.
 Global Custody. In terms of assets under administration, global custody is one
of the fastest growing products within C&IS. This product provides the
necessary service capabilities for the growing volume of foreign assets that
are held by U.S. and non-U.S. domiciled clients. Northern Trust continues to
strengthen global securities processing and invest in the required systems
capabilities and sub-custodial network in order to capitalize on the growth
opportunities presented by the development of worldwide financial markets.
Through its worldwide network of subcustodians in 70 countries, Northern Trust
had global assets of approximately $108 billion under administration at
December 31, 1996 which is 27% greater than last year.
 Competition. Competition in the corporate and institutional business has been
impacted by recent financial services mergers and acquisitions and further
consolidation in the industry as other providers exit the business. In the
third quarter of 1996, Northern Trust was named preferred provider of master
trust and domestic institutional custody services for clients of First Chicago
NBD as it exits that business. Through January 1997, clients with approximately
$29.0 billion in trust assets and annualized fee revenues of approximately $8.3
million have selected Northern Trust. The transition of these clients is
expected to be completed during the first half of 1997. Targeted marketing
efforts continue.
 Competition has remained intense in the master trust/master custody business
affecting the pricing of associated products and services. Northern Trust
believes that it is positioned to deal with these pressures and maintain
profitability because of its focus on individual client service, developing
deeper client relationships that include a range of services, economies of
scale and technological innovation.

Note: Certain reclassifications have been made to prior years' financial
information to conform to the current year presentation.

 PERSONAL FINANCIAL SERVICES. Northern Trust has positioned itself in states
having significant concentrations of wealth and growth potential. With the
addition of seven new offices in 1996 and three offices in early 1997, Northern
Trust's unique national network of Personal Financial Services offices includes
60 locations in Illinois, Florida, California, Arizona, and Texas. PFS also
includes the Wealth Management Group which provides customized products and
services to meet the complex financial needs of families throughout the country
with assets typically exceeding $100 million. At December 31, 1996 trust assets
under administration in PFS totaled $85.2 billion, an increase of 22% from
$69.6 billion at December 31, 1995. Trust fees increased 13% in 1996 to $294.0
million while 1995 trust fees totaled $260.8 million, an increase of 10% from
$236.7 million in 1994. Although all geographic markets contributed to the 1996
increase, the strongest fee growth occurred in the Wealth Management Group and
the Chicago, Florida and Texas markets. With an established presence and
expanding network in growing markets, Northern Trust believes that it has the
momentum to continue to grow personal trust fees.
 Illinois. Personal trust fees in Illinois increased 10% to $130.2 million in
1996 from $118.5 million in 1995, which was up 5% from $113.3 million in 1994.
Trust assets under administration totaled $35.1 billion at December 31, 1996
compared with $30.4 billion a year ago. Over the years clients have been
attracted by both the quality of trust services and the financial strength and
stability which Northern Trust has consistently achieved. These qualities,
combined with credit ratings that are top tier, have allowed Northern Trust to
enhance the growth of its personal trust business. It is expected that the
Chicago area market will continue to be a significant contributor to personal
trust revenues.
 Florida. Northern Trust continues to strengthen its position in the Florida
marketplace. Trust fees for 1996 totaled $77.3 million, up 17% from $65.9
million in 1995 which was up 15% from $57.2 million in 1994. Trust assets under
administration were $15.3 billion at December 31, 1996, and $13.2 billion at
year-end 1995, making Northern Trust the second largest provider of personal
trust services in Florida. The five-year compound growth rates for trust fees
and trust assets have been 14% and 13%, respectively. With new offices opened
in Bonita Springs, Delray Beach and Stuart during 1996 and Tampa in 1997,
Northern Trust now has twenty-three offices located in coastal communities
encompassing the southern half of the state. Management believes there remains
significant opportunity for growth in and around the markets currently served
in Florida.
 California. With the opening of offices in La Jolla and Montecito in early
1997, Northern Trust's California subsidiary has eight offices strategically
located throughout the state to reach the California trust market. Trust fees
for 1996 increased 7% to $39.5 million from $37.0 million in 1995 which was up
9% from $34.0 million in 1994. Trust assets under administration totaled $7.3
billion at December 31, 1996 and $6.1 billion at December 31, 1995.
 Arizona. Northern Trust Bank of Arizona N.A. is one of the largest providers
of personal trust services in the state. As in other markets, the strategy in
Arizona includes providing private banking and trust services to targeted high
net worth individuals. New offices were established during 1996 in Sun City
West and Mesa, bringing to six the total number of offices in this growing
market. Trust fees from this market were $15.4 million in 1996, $13.7 million
in 1995 and $12.8 million in 1994. Assets under administration at December 31,
1996 and 1995 totaled $2.6 billion and $2.1 billion, respectively.
 Texas. Northern Trust expanded its growing presence in Texas during 1996 with
the acquisition of Metroplex Bancshares, Inc., parent company of Bent Tree
National Bank (Bent Tree) in Dallas, Texas. The acquisition added a north
Dallas location to Northern Trust's six

                                                                              21

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

existing facilities in Dallas and Houston, the two most important metropolitan
markets in the state. Northern Trust has expanded from one office to seven
offices since its entry into the Texas market in 1989. The Texas facilities
have experienced the highest percentage growth rate for the past two years for
both trust fees and assets under administration of any of the states served by
Northern Trust. Trust fees for 1996, 1995 and 1994 were $8.6 million, $6.9
million and $4.6 million, respectively. Trust assets under administration were
$2.3 billion at December 31, 1996 and $1.9 billion at December 31, 1995.
 Wealth Management. Trust fees in the rapidly growing national Wealth
Management Group grew 22% to $23.0 million in 1996 from $18.8 million in 1995,
which was up 27% from $14.8 million in 1994. This group had $22.6 billion of
trust assets under administration, a 42% increase from a year ago. The 140
families serviced by this group benefit from Northern Trust's sophisticated
master trust and global custody services and the reporting capabilities of the
Passport electronic delivery system.
 Expansion. The national personal trust strategy focuses primarily on
increasing market share in present geographic locations and other selected
upscale personal markets. In Florida, Northern Trust plans to expand into
additional counties over the next three to five years. Selective acquisitions
may be made where they can accelerate the pace of expansion. Northern Trust
also plans to establish offices in the newer growth areas around Phoenix and
Tucson, Arizona during the next several years. In Illinois, Northern Trust
expects to establish new offices in several Chicago suburban communities, and
an additional inner city location is also contemplated.
 INVESTMENT MANAGEMENT. Northern Trust's investment management business
benefited significantly in 1996 from strong equity markets around the world, as
well as from broader industry trends, including the increasing preference of
investors to concentrate assets with fewer managers, the globalization of the
financial markets and a greater focus on risk evaluation and management.
Northern's competitive investment results, successful expansion of client
relationships and new product offerings contributed to continued growth in
assets under management. Today, Northern Trust manages $130.3 billion for
personal and institutional clients, up 23% from year-end 1995, placing Northern
Trust among the largest, and fastest growing, investment managers worldwide.
 Investment management performance for bond accounts has been consistently in
the top quartile over the past ten years, as measured by SEI Investment
Management Consulting, a nationally recognized plan sponsor consultant.
Investment management performance for equity accounts was solidly above the
median for the one, seven and ten year cumulative performance periods ended
December 31, 1996, as measured by SEI. Northern Trust leveraged its investment
expertise with the establishment in 1994 of a second mutual fund family, the
Northern Funds. Assets in this family of 19 no-load funds have grown to $4.3
billion at year-end 1996. This mutual fund family serves the investment needs
of personal clients, while the $8.3 billion Benchmark family of mutual funds
continues to serve the needs of institutional clients.
 FOREIGN EXCHANGE TRADING PROFITS. Foreign exchange trading profits totaled a
record $58.8 million, up 6% from $55.3 million reported a year ago, which was
up from $35.9 million in 1994. A substantial component of foreign exchange
profits continued to result from transactions associated with the growing
global custody business. As custodian, Northern Trust provides foreign exchange
services in the normal course of business. Active management of currency
positions, within conservative limits, produced an ancillary component of
aggregate trading profits. The opening of Northern's Singapore Branch in
October, 1996 established round-the-clock foreign exchange capabilities to
better serve global custody clients in the Asian region.
 TREASURY MANAGEMENT FEES. The fee portion of treasury management revenues
totaled $55.3 million in 1996, an 11% increase from the $49.6 million reported
in 1995 compared with $46.3 million in 1994. Total treasury management
revenues, which, in addition to fees, include the computed value of
compensating deposit balances, increased 11% to $86.0 million from $77.5
million in 1995 compared to $73.0 million in 1994, reflecting the continued
growth in new business in both paper- and electronic-based products.
 SECURITY COMMISSIONS AND TRADING INCOME. Security commissions and trading
income totaled $23.9 million in 1996, compared with $21.7 million in 1995 and
$22.0 million in 1994. This income is primarily generated from securities
brokerage and futures contract services. Additional revenue is provided from
underwriting selected general obligation tax-exempt securities and interest
risk management activities with clients. The 1996 results reflect strong growth
in security brokerage activities offset by a decline in the clearing volume of
futures contracts.
 OTHER OPERATING INCOME. Other operating income includes loan, letter of credit
and deposit-related service fees and other miscellaneous income from asset
sales. Other operating income in 1996 totaled $47.2 million compared with $45.5
million in 1995 and $75.9 million in 1994. The 1994 results included a $28.5
million pretax gain on the sale of Northern's investment in BSS, which was net
of approximately $6.0 million in ancillary and other sale-related transition
costs associated with the transfer of custody accounts from BSS to the Bank's
London Branch. The slight increase in other operating income in 1996 reflects a
gain from the sale of the Bank's merchant charge card business which was
partially offset by a decrease in gains realized from the sale of lease
residuals.

this total, $.5 million resulted from held to maturity securities that were
called at a premium, offset in part by $.1 million of net losses from the sale
of securities classified as available for sale. This compares with net gains of
$1.0 million in 1995 and $.1 million of net losses in 1994.
NET INTEREST INCOME. Net interest income is defined as the total of interest
income and amortized fees on earning assets less interest expense on deposits
and borrowed funds, adjusted for the impact of off-balance sheet hedging
activity. Earning assets, which consist of securities, loans and money market
assets, are financed by a large base of interest-bearing funds, including
retail deposits, wholesale deposits, short-term borrowings, senior notes and
long-term debt. Earning assets are also funded by net noninterest-related
funds. Net noninterest-related funds consist of demand deposits, the reserve
for credit losses and stockholders' equity, reduced by nonearning assets
including cash and due from banks, items in process of collection, buildings
and equipment and other net nonearning assets. Variations in the level and mix
of earning assets, interest-bearing funds and net noninterest-related funds,
and their relative sensitivity to interest rate movements, are the dominant
factors affecting net interest income. In addition, net interest income is
impacted by the level of nonperforming assets and client use of compensating
balances to pay for services.
 Net interest income for 1996 was a record $388.3 million, up 9% from $357.6
million in 1995, which was up 7% from $334.6 million in 1994. When adjusted to
a fully taxable equivalent (FTE) basis, yields on taxable, nontaxable and
partially taxable assets are comparable, although the adjustment to a FTE basis
has no impact on net income. Net interest income on a FTE basis for 1996 was a
record $421.9 million, an increase of $26.7 million or 7% from $395.2 million
in 1995 which in turn was up 7% from $368.0 million in 1994. Through steady
asset growth and conservative interest rate risk management, Northern Trust has
been successful in generating year over year improvement in net interest income
as evidenced by the fact that 1996 represents the thirteenth consecutive year
of record performance. The increase in FTE net interest income in 1996 was
essentially attributable to growth in average earning assets, which was
partially offset by a decline in the net interest margin to 2.25% from 2.30%
last year and 2.34% in 1994.
 Earning assets averaged $18.8 billion, up 9% or $1.6 billion from the $17.2
billion reported in 1995, which was up from $15.7 billion in 1994. The growth
in average earning assets reflects a 13% or $1.2 billion increase in loans, a
3% or $171 million increase in securities and a 12% or $219 million increase in
money market assets. Loan volume for the year averaged $10.3 billion with
virtually all of the growth reflected in the domestic portfolio while
international loans increased $36 million. The domestic growth came principally
from residential mortgage activities, up $501 million, and commercial and
industrial loans, up $229 million. Reflected in the total loan growth are non-
interest bearing domestic and international overnight advances related to
processing certain trust client investments, which averaged $596 million in
1996, down 10% from a year ago. Securities averaged $6.4 billion

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
- --------------------------------------------------------------------------------

in 1996 versus $6.2 billion in 1995, due primarily to a $476 million increase
in short-term U.S. Government securities, offset in part by a decline in other
securities. Money market assets averaged $2.1 billion in 1996 versus $1.9
billion in 1995.
 The increase in average earning assets of $1.6 billion was funded through
growth in interest-bearing deposits, other interest-related funding sources,
and noninterest-related funds. The deposit growth was concentrated primarily in
savings and money market deposits (up $308 million) and global custody deposit
activity in the Cayman Islands Branch (up $446 million), offset in part by a
reduction in the London Branch of $162 million. Other interest-related funds
averaged $5.9 billion, up $682 million, principally from federal funds
purchased (up $278 million), securities sold under agreements to repurchase (up
$203 million) and other borrowings (up $240 million). Average net noninterest-
related funds increased $194 million, mainly due to higher stockholders' equity
and noninterest-bearing time and savings deposits. Stockholders' equity for the
year averaged $1.5 billion, an increase of $113 million or 8% from 1995,
principally due to the strong earnings performance, offset in part by the
repurchase of common stock pursuant to the Corporation's share buyback program.
 The net interest margin declined to 2.25% from 2.30% last year due primarily
to lower spreads on the higher volume of short-term liquid assets funded by
short-term liabilities, coupled with lower loan-related fees. The margin was
also impacted by a slightly higher reliance on interest-related funding sources
to fund asset growth.
 
PROVISION FOR CREDIT LOSSES. Asset quality remained exceptionally strong as
nonperforming assets declined to $21.4 million, their lowest level in over
fifteen years. The provision for credit losses increased to $12.0 million in
1996, up from $6.0 million in each of the last two years. For a discussion of
the reserve for credit losses, refer to pages 30 and 31.
 
NONINTEREST EXPENSES. Noninterest expenses for 1996 totaled $766.8 million, up
$57.6 million or 8% from $709.2 million in 1995, which was up 1% from $700.5
million in 1994. Total expenses for 1996 included $25.3 million of incremental
expenses resulting from acquisitions. As a result of a reduction in premium
rates, FDIC insurance expense declined by $8.5 million compared to last year.
Exclusive of these items for both years, 1996 noninterest expenses increased 6%
over last year. In addition to acquisitions, expense increases during 1996
reflect a variety of growth initiatives, including investments in technology,
PFS office expansion, the opening of a Singapore office, and staff additions
and higher operating expenses necessary to support new business and growing
transaction volumes. Incentive compensation also increased, reflecting client
investment portfolio performance, excellent new business development results,
record earnings and the impact of the Corporation's higher stock price on
stock-based performance plans. These increases were partially offset by cost
savings from changes in several benefit plans effective January 1, 1996 and
favorable medical plan claim experience.
 The modest increase in 1995 noninterest expenses from 1994 results reflects
the impact of $30.9 million of nonrecurring charges in 1994. Adjusting for
these items, noninterest expenses grew 6% from 1994 to 1995 primarily as a
result of salary adjustments, higher incentive compensation and incremental
expenses from 1995 acquisitions.
 The productivity ratio, defined as noninterest income plus net interest income
on a taxable equivalent basis before the provision for credit losses, divided
by noninterest expenses, was 156% for 1996 compared with 151% in 1995 and 143%
in 1994.
 SALARIES AND BENEFITS. Salaries and benefits, which represent 58% of total
noninterest expenses, increased 5% to $441.3 million in 1996 from $419.1
million in 1995, which was up 7% from $391.4 million in 1994. Salary costs, the
largest component of noninterest expenses, totaled $368.8 million, up $31.2
million or 9% from $337.6 million a year ago. The principal items contributing
to the change in 1996 were salary adjustments, incentive compensation, and
staff additions resulting from acquisitions and to support Northern Trust's
growing trust activities and office expansion. The incentive-based compensation
expense increase reflects the impact of client investment portfolio performance
and record new business development results, as well as the 1996 record
earnings performance and the price increase in Northern Trust Corporation
common stock. Included in the 1995 results was $3.3 million in severance costs
associated with staff reductions, while the 1994 results included a $4.2
million addition to salary expense relating to overtime back pay obligations.
 Staff on a full-time equivalent (FTE) basis averaged 6,665 compared with 6,548
in 1995 and 6,420 in 1994. The growth in staff during 1996 is the result of
acquisitions and other staff additions primarily in the last half of the year.
As of December 31, 1996, staff levels on a FTE basis totaled 6,933, an increase
of 6% from 6,531 at the end of last year.
 As part of Northern Trust's ongoing program to control expense growth, a
complete review of all employee benefit plans was conducted at the end of last
year. As a result of this review, changes, effective January 1, 1996, were made
to the pension, medical, Thrift Incentive and ESOP plans. Employee benefit
costs for 1996 totaled $72.5 million, down $9.0 million or 11% from $81.5
million in 1995 which was up 9% from $74.8 million in 1994. The majority of the
1995 increase in benefit costs was attributable to higher medical and
retirement benefit expenses and payroll taxes.
 OCCUPANCY EXPENSE. Net occupancy expense totaled $63.8 million, up 6% or $3.6
million from $60.2

million in 1995, which was up 5% from $57.4 million in 1994. The principal
components of the 1996 increase were higher building and leasehold improvement
amortization expenses and rental and operating costs primarily associated with
business expansion.
 EQUIPMENT EXPENSE. Equipment expense, which includes depreciation, rental, and
maintenance costs, totaled $54.6 million in 1996, 12% or $6.0 million higher
than the $48.6 million in 1995, which was down 14% from the $56.4 million in
1994. Included in the 1994 expense is $11.2 million of nonrecurring expenses
resulting from the trade-in and the sale and leaseback of mainframe computer
equipment. Excluding these items, the expense levels in each of the three years
primarily reflect planned increases in equipment and computer depreciation and
related costs to support trust and banking business expansion.
 OTHER OPERATING EXPENSES. Other operating expenses for 1996 totaled $207.1
million, up 14% from $181.3 million in 1995, which was down 7% from $195.3
million in 1994. The increase in the 1996 expense level was primarily the
result of acquisitions, continued investment in technology, expansion of the
personal trust and banking office network, and higher operating expenses
necessary to support business growth. These initiatives resulted in increases
in computer software amortization, transaction-based depository fees, technical
and consulting service fees and amortization of intangible assets. These
increases, along with higher costs incurred from processing errors, were
partially offset by lower levels of FDIC deposit insurance premiums. Included
in the 1995 results are $4.1 million of pension settlement charges. Other
operating expenses in 1994 included $9.6 million in pension settlement charges,
a $3.5 million expense relating to an agreement between the Corporation and The
Benchmark Funds, and a $2.4 million write-down of older trust-related software.
 Investments in technology are designed to support and enhance the transaction
processing and securities handling capability of the trust and banking
businesses. Additional capital expenditures planned for systems technology will
result in future expenses for the depreciation of hardware and amortization of
software. Depreciation and software amortization are charged to equipment and
other operating expenses, respectively.
 
PROVISION FOR INCOME TAXES. The provision for income taxes was $128.6 million
in 1996 compared with $100.5 million in 1995 and $79.3 million in 1994. The
effective tax rate was 33% for 1996 compared with 31% for 1995 and 30% for
1994. The higher tax provision in 1996 resulted from the growth in earnings for
both federal and state income tax purposes while federally tax-exempt income
declined.
 
SUBSEQUENT IMPLEMENTATION OF STATEMENT OF FINANCIAL ACCOUNTING STANDARDS.
Statement of Financial Accounting Standards (SFAS) No. 125, "Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities," provides accounting and reporting standards for a variety of
transactions, including loan participations, sales of assets where servicing of
the assets is retained, repurchase agreements and securities lending
transactions. The portions of SFAS No. 125 that address accounting for loan
participations and sales of assets where servicing of the assets is retained
were implemented, as required, on January 1, 1997 and did not have a material
impact on Northern Trust's consolidated financial statements. The remainder of
SFAS No. 125 is expected to be implemented effective January 1, 1998 and is not
expected to materially impact the consolidated financial statements.
 
FINANCIAL CONDITION
Average earning assets in 1996 increased 9% to $18.8 billion. Approximately 11%
of the growth in average earning assets resulted from the full year impact of
prior year acquisitions, as well as the fourth quarter 1996 addition of Bent
Tree National Bank. The growth, including acquisitions, was concentrated
primarily in residential mortgages, commercial and industrial loans, and short-
term U.S. Government securities and money market assets. A high quality and
liquid balance sheet is maintained with securities and money market assets
averaging $8.4 billion or 45% of total earning assets.
 The management strategy for investment securities is to maintain a very high
quality portfolio with generally short-term maturities. To maximize after-tax
income, investments in tax-exempt municipal securities are utilized but with
somewhat longer maturities. The average balance of the securities portfolio,
which includes securities held to maturity and available for sale, increased 3%
from last year to $6.4 billion. U.S. Government securities averaged $1.7
billion in 1996, up $476 million from 1995 levels. U.S. Government securities
had an average maturity of seven months at December 31, 1996, compared with
eleven months at the prior year-end. Average municipal securities declined $21
million to average $414 million and provided a fully taxable equivalent yield
of 9.86%. The average maturity of municipal securities was 82 months, up from
78 months a year ago. Federal agency securities averaged $4.0 billion in 1996,
down slightly from 1995, and had an average maturity at December 31, 1996 and
1995 of six months and nine months, respectively. Other securities, consisting
primarily of preferred stock and privately issued collateralized mortgage
obligations, averaged $228 million, down from $353 million last year.
 Included in federal agency securities were $376 million of agency issued
collateralized mortgage obligations (CMO's). Included in other securities were
$41 million of privately issued CMO's, all of which are rated triple-A and $12
million of which are collateralized by federal agency securities. CMO's in
general have widely varying degrees of risk, which derives from the prepayment
risk on the

underlying mortgage loans. Northern Trust invests only in CMO's that have
lesser degrees of prepayment risk. Of all CMO's held during 1996, $51 million
paid a fixed rate of interest and $342 million paid a floating rate indexed to
LIBOR. The fixed rate CMO's had an average life of 13 months at year-end 1996,
based on an average of dealer prepayment estimates. As a result of the short
average life, the prepayment risk of the fixed rate CMO's was immaterial. The
floating rate CMO's had an average life of 32 months at year-end 1996, and have
rate caps ranging from 9% to 14%, with an average cap of 10%.
 Approximately $1.0 billion of federal agency and other securities have
variable rates that are reset at least every six months to reflect the level of
short-term interest rates. At year-end 1996, the fair value of the securities
portfolio of $4.8 billion exceeded the book value of these securities by $20.5
million.
 Loans averaged $10.3 billion in 1996 and increased 13% from the prior year.
Average domestic loans increased 13% to $9.9 billion for the year while the
average international portfolio increased to $380 million from $344 million in
1995. The increase in the average domestic loan portfolio reflects substantial
growth in residential mortgages which increased 14% on average and totaled $4.6
billion at year-end. Commercial and industrial loans also contributed to the
growth in the domestic portfolio, increasing 8% to average $3.3 billion for the
year. During the year, commercial real estate loans increased $45 million due
in part to acquisitions, and at December 31, 1996, totaled $558 million
representing 5% of domestic loans.
 Money market assets averaged $2.1 billion, up 12% or $219 million from last
year.
 Total interest-related funds averaged $15.9 billion in 1996, up $1.4 billion
or 10% from 1995. Savings and money

market deposits increased 9% and averaged $3.6 billion while foreign office
time deposits increased $333 million or 10%. The increase in foreign time
deposits resulted primarily from greater global custody activity, particularly
in the Cayman Islands Branch. Federal funds purchased, securities sold under
agreements to repurchase, and other borrowings collectively increased $721
million on average compared to the prior year. The balances within these
classifications vary based upon funding requirements, interest rate levels, and
the availability of collateral used to secure these borrowings. Balances in
other borrowings primarily represent treasury, tax and loan note option
balances which provide a funding source at an attractive rate relative to
federal funds. Deposits related to trust activities in the domestic banking
subsidiaries, coupled with growth of the global custody business, continued to
have a significant impact on the balance sheet as these deposits in 1996
averaged $4.3 billion representing 33% of total deposits. Senior notes averaged
$267 million, down $127 million from last year.
 In September, The Northern Trust Company issued $100 million of 7.30%
Subordinated Notes due 2006. The notes were issued under the terms of an
Offering Circular allowing The Northern Trust Company to offer subordinated
bank notes and up to $1.7 billion aggregate principal amount at any time
outstanding of its senior bank notes (less certain senior bank notes issued
prior to April 1993 and still outstanding), with maturities ranging from 30
days to 15 years. The senior notes are issued periodically and provide an
additional funding source for the Bank. At December 31, 1996, an additional
$100 million of subordinated bank notes with maturities ranging from 5 years to
15 years can be issued under the terms of the Offering Circular.
 On January 16, 1997, the Corporation issued $150 million of Floating Rate
Capital Securities through a wholly owned statutory business trust. The
securities, which qualify as Tier 1 capital for regulatory purposes, were
issued at a discount to yield 60.5 basis points above the three-month London
Interbank Offered Rate.
 
CAPITAL EXPENDITURES
Northern Trust's Management Committee reviews and approves proposed capital
expenditures which exceed $500,000. This process assures that the major
projects to which Northern Trust commits its resources produce benefits
compatible with corporate strategic goals.
 During 1996, Northern Trust continued to improve its hardware and software
capabilities, especially related to trust activities. Such improvements help
assure that Northern Trust offers state-of-the-art technology which enables
clients to obtain the highest level of quality service within a competitive
cost structure, a characteristic which helps distinguish Northern Trust from
its competitors. In this regard, through the efforts of internal staff and
outside consultants, Northern Trust completed installation of several
significant phases of its new trust management system, including the creation
of new personal client statements and enhancements to the accounting systems.
In addition, major systems development efforts in 1996 focused on Passport and
retirement services products. Passport is Northern Trust's next generation of
on-line desktop delivery services first offered to clients in 1995. Retirement
services bring together a comprehensive array of Master Trust, participant
recordkeeping, retirement plan design and actuarial services. The unamortized
capitalized cost of corporate-wide software development projects at December
31, 1996 was $133.8 million, of which $82.8 million represented the book value
of the trust management system. Northern Trust's 1997 technology initiatives
will include the continued development of Passport and retirement services
products and enhancements to multicurrency operating and accounting systems.
 Capital expenditures in 1996 also included the leasehold improvements and
furnishings associated with the opening of new offices in Florida and Arizona
and the construction costs for the Chicago South Financial Center and the new
Winnetka, Illinois office, both of which opened in the third quarter, as well
as expansion in several existing offices.
 Capital expenditures for 1996 totaled $93.7 million of which $17.1 million was
for building and leasehold improvements, $5.4 million for furnishings, $33.5
million for hardware and machinery and $37.7 million for software. During 1997,
in addition to its technology initiatives, Northern Trust will continue to
invest in the expansion of the five-state network of Personal Financial
Services offices.
 
RISK MANAGEMENT
ASSET QUALITY AND CREDIT RISK MANAGEMENT.
SECURITIES. A high quality securities portfolio is maintained with 85% of the
total portfolio comprised of U.S. Treasury or federal agency securities. The
remainder of the portfolio is comprised of obligations of states and political
subdivisions, preferred stock and other securities. At December 31, 1996, 75% of
these securities were rated triple-A or double-A, 22% were rated single-A and 3%
were below A or not rated by Standard and Poor's and/or Moody's Investors
Service. Other securities consist primarily of privately issued collateralized
mortgage obligations, backed by federal agency securities or mortgage loans.
 Northern Trust is an active participant in the repurchase agreement market.
This market provides a relatively low cost alternative for short-term funding.
Securities sold under repurchase agreements are held by the counterparty until
the repurchase transaction matures. Increases in the fair value of these
securities in excess of the repurchase liability could subject Northern Trust
to credit risk in the event of default by the counterparty. To minimize this
risk, collateral values are continuously monitored and Northern Trust sets
limits on exposure with counterparties and regularly assesses their financial
condition.

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
- --------------------------------------------------------------------------------

LOANS AND OTHER EXTENSIONS OF CREDIT. A certain degree of credit risk is
inherent in Northern Trust's various lending activities. Credit risk is managed
through the Credit Policy function, which is designed to ensure adherence to a
high level of credit standards. Credit Policy provides a system of checks and
balances for Northern Trust's diverse credit-related activities by establishing
and monitoring all credit-related policies and practices throughout Northern
Trust and ensuring their uniform application. These activities are designed to
ensure that credit exposure is diversified on an industry and client basis,
thus lessening overall credit risk. These credit management activities also
apply to Northern Trust's use of derivative financial instruments, including
foreign exchange contracts and interest risk management instruments.
 A further way in which credit risk is managed is by requiring collateral.
Management's assessment of the borrower's creditworthiness determines whether
collateral is obtained. The amount and type of collateral held varies but may
include deposits held in financial institutions, U.S. Treasury securities,
other marketable securities, income-producing commercial properties, accounts
receivable, property, plant and equipment, and inventory. Collateral values are
monitored on a regular basis to ensure that they are maintained at an
appropriate level.
 The largest component of credit risk relates to the loan portfolio. Although
credit exposure is well-diversified, there are certain groups that meet the
accounting definition under SFAS No. 105 of credit risk concentrations.
According to this statement, group concentrations of credit risk exist if a
number of borrowers or other counterparties are engaged in similar activities
and have similar economic characteristics that would cause their ability to
meet contractual obligations to be similarly affected by changes in economic or
other conditions. The fact that an extension of credit falls into one of these
groups does not indicate that the credit has a higher than normal degree of
credit risk. These groups are: residential real estate, middle market companies
and small businesses, banks and bank holding companies and commercial real
estate.
 RESIDENTIAL REAL ESTATE. The residential real estate loan portfolio totaled
$4.6 billion or 43% of total domestic loans at December 31, 1996, compared with
$3.9 billion or 41% at December 31, 1995. Residential real estate loans consist
of conventional home mortgages and equity credit lines, which generally require
a loan to collateral value of 75% to 80%. Of the total $4.6 billion in
residential real estate loans, $2.6 billion were in the greater Chicago area
with the remainder distributed throughout the other geographic regions served
by Northern Trust. Legally binding commitments to extend credit, which are
primarily equity credit lines, totaled $405.8 million and $372.2 million as of
December 31, 1996 and 1995, respectively.
 MIDDLE MARKET COMPANIES AND SMALL BUSINESSES. Credit exposure to middle market
companies and small businesses is primarily in the form of commercial loans,
which totaled $1.4 billion at December 31, 1996 and $1.2 billion as of December
31, 1995. These loans are to a diversified group of borrowers that are
predominantly in the manufacturing, wholesaling, distribution and services
industries, with total sales of less than $500 million. The largest component
of this group of borrowers is located in the greater Chicago area. Middle
market and small businesses have been an important focus of business
development, and it is part of the strategic plan to continue to selectively
grow the portfolio with such entities. The credit risk associated with middle
market and small business lending is principally influenced by general economic
conditions and the resulting impact on the borrower's operations.
 Off-balance sheet credit exposure to middle market companies and small
businesses in the form of legally binding commitments to extend credit, standby
letters of credit, and commercial letters of credit totaled $1.5 billion,
$748.7 million, and $18.1 million, respectively, as of December 31, 1996, and
$1.2 billion, $405.6 million, and $12.5 million, respectively, as of December
31, 1995.
 BANKS AND BANK HOLDING COMPANIES. On-balance sheet credit risk to banks and
bank holding companies, both domestic and international, totaled $4.4 billion
and $3.0 billion at December 31, 1996 and 1995, respectively. The majority of
this exposure consisted of short-term money market assets, which totaled $3.1
billion and $1.7 billion as of December 31, 1996 and 1995, respectively, and
noninterest-bearing demand balances maintained at correspondent banks which
totaled $896 million as of December 31, 1996, compared to $1.0 billion at year-
end 1995. Commercial loans to banks totaled $247 million and $195 million,
respectively, as of December 31, 1996 and 1995. The majority of these loans
were to U.S. bank holding companies, primarily in the seventh Federal Reserve
District, for their acquisition purposes. Such lending activity is limited to
entities which have a substantial business relationship with Northern Trust.
Legally binding commitments to extend credit to banks and bank holding
companies totaled $178 million and $155 million as of December 31, 1996 and
1995, respectively.
 COMMERCIAL REAL ESTATE. In managing its credit exposure, management has
defined a commercial real estate loan as one where: (1) the borrower's
principal business activity is the acquisition of or the development of real
estate for commercial purposes; (2) the principal collateral is real estate
held for commercial purposes and loan repayment is expected to flow from the
operation of the property; or (3) the loan repayment is expected to flow from
the sale or refinance of real estate as a normal and ongoing part of the
business. Unsecured lines of credit to firms or individuals engaged in
commercial real estate endeavors are included without regard to the use of loan
proceeds. The
 
28
Northern Trust Corporation
<PAGE>
 
commercial real estate portfolio consists of interim loans and commercial
mortgages.
 The interim loans, which totaled $236.3 million and $184.5 million as of
December 31, 1996 and 1995, respectively, are composed primarily of loans to
developers that are highly experienced and well-known to Northern Trust. Short-
term interim loans provide financing for the initial phases of the acquisition
or development of commercial real estate, with the intent that the borrower
will refinance the loan through another financial institution or sell the
project upon its completion. The interim loans are primarily in the Chicago
market in which Northern Trust has a strong presence and a thorough knowledge
of the local economy.
 Commercial mortgage financing, which totaled $321.4 million and $328.1 million
as of December 31, 1996 and 1995, respectively, is provided for the acquisition
of income producing properties. Cash flows from the properties generally are
sufficient to amortize the loan. These loans average less than $500,000 each
and are primarily located in the suburban Chicago and Florida markets.
 At December 31, 1996, off-balance sheet credit exposure to commercial real
estate developers in the form of legally binding commitments to extend credit
and standby letters of credit totaled $61.5 million and $22.5 million,
respectively. At December 31, 1995, legally binding commitments were $21.7
million and standby letters of credit were $16.5 million.
 
FOREIGN OUTSTANDINGS. In recent years international banking activities have
been focused on import and export financing for U.S. based clients and on
correspondent banking. Northern Trust has extensive treasury activities
involving short-term, credit-related business with foreign financial
institutions. Interbank time deposits with foreign banks represent the largest
category of foreign outstandings. The Chicago head office and the London Branch
actively participate in the interbank market with U.S. and foreign banks.
 As used in this discussion, foreign outstandings are cross-border outstandings
as defined by the Securities and Exchange Commission. They consist of loans,
acceptances, interest-bearing deposits with financial institutions, accrued
interest and other monetary assets. Not included are letters of credit, loan
commitments, and foreign office local currency claims on residents funded by
local currency liabilities. Foreign outstandings related to a specific country
are net of guarantees given by third parties resident outside the country and
the value of tangible, liquid collateral held outside the country. However,
transactions with branches of foreign banks and corporations are included in
these outstandings and are classified according to the country location of the
foreign entities' head office.
 Risk related to foreign outstandings is continually monitored and internal
limits are imposed on foreign exposure. The following table provides
information on foreign outstandings by country that exceed 1.00% of Northern
Trust's consolidated assets.

There were no aggregate foreign outstandings by country falling between 0.75%
and 1.00% of total assets at December 31, 1996 and 1995. This compares with
$154 million to Germany in 1994.
 
NONPERFORMING ASSETS AND 90 DAY PAST DUE LOANS. Nonperforming assets consist of
nonaccrual loans, restructured loans and Other Real Estate Owned (OREO). OREO
is comprised of commercial and residential properties acquired in partial or
total satisfaction of problem loans. Past due loans are loans that are
delinquent 90 days or more and still accruing interest. The balance in this
category at any reporting period can fluctuate widely based on the timing of
cash collections, renegotiations and renewals.
 Maintaining a low level of nonperforming assets is important to the ongoing
success of a financial institution. Northern Trust's comprehensive credit
review and approval process is critical to the ability to minimize
nonperforming assets on a long-term basis. In addition to the negative impact
on both net interest income and credit losses, nonperforming assets also
increase operating costs due to the expense associated with collection efforts.
 The table on the following page presents the nonperforming assets and past due
loans for the current year and the prior years. Of the total loan portfolio of
$10.9 billion at December 31, 1996, $19.5 million or .18% was nonperforming, a
decrease of $12.4 million from year-end 1995.
 Included in the portfolio of nonaccrual loans are those which meet the
criteria as being "impaired" under the definition in SFAS No. 114. A loan is
impaired when, based on current information and events, it is probable that a
creditor will be unable to collect all amounts due according to the contractual
terms of the loan agreement. As of December 31, 1996, impaired loans, which
also have been classified as nonperforming, totaled $16.8 million, with $.5
million of the reserve for credit losses allocated to these loans.

RESERVE FOR CREDIT LOSSES. In evaluating the adequacy of the reserve for credit
losses, management relies predominantly on a disciplined credit review process
which is applicable to the full range of the credit exposures. The review
process, directed by Credit Policy, is intended to identify as early as
possible clients who might be facing financial difficulties. Once identified,
the extent of the client's financial difficulty is carefully monitored by
Credit Policy, which recommends to management the portion of any credits that
need a specific reserve allocation or should be charged-off. Other factors
considered by management in evaluating the adequacy of the reserve include: the
relative size of the subsidiary banks' single loan lending limits; loan volume;
historical net loan loss experience; level and composition of nonaccrual, past
due and restructured loans; the condition of industries and geographic areas
experiencing or expected to experience particular economic adversities;
international developments; current and anticipated economic conditions; credit
evaluations; and the liquidity and volatility of the markets. From time to time
specific amounts of the reserve are designated for certain loans in connection
with management's analysis of the adequacy of the reserve for credit losses, as
well as its evaluation of impaired loans.
 The reserve balance is not a precise amount, but is derived from judgments
based on the above factors. It represents management's best estimate of the
reserve for credit losses necessary to adequately cover probable losses from
current credit exposures. The provision for credit losses is the charge against
current earnings that is determined by management as the amount needed to
maintain an adequate reserve.
 The overall credit quality of the domestic portfolio has remained good as
evidenced by the relatively low level of nonperforming loans and net charge-
offs. Management's assessment of the financial condition of specific clients
facing financial difficulties, and portfolio growth relating to low-risk
residential lending and bank acquisitions, were among the factors impacting
management's analysis of the adequacy of the reserve. The combination of these
factors resulted in a reserve for credit losses of $148.3 million at December
31, 1996, compared with $147.1 million last year. The decline in the year-end
reserve for credit losses as a percentage of outstanding loans and leases from
1.49% to 1.36% at year-end 1996 is primarily attributable to loan growth in
low-risk residential lending and improved credit quality. The following table
summarizes the changes in the reserve for credit losses for the current year
and the prior years.
 
INTEREST RATE RISK MANAGEMENT
Policies and limits for the management of Northern Trust's interest rate risk
are established by the Board of Directors. To ensure adherence to these
policies and limits, the Corporate Asset and Liability Policy Committee (ALCO)
establishes and monitors guidelines on the sensitivity of earnings to changes
in interest rates caused by on- and off-balance sheet positions. The goal of
the ALCO process is to manage the balance sheet to provide the maximum level of
earnings while maintaining a high quality balance sheet and acceptable levels
of interest rate risk and liquidity risk.
 Sensitivity of earnings to interest rate changes arises when yields on assets
change differently from the interest costs on liabilities. To mitigate this
interest rate risk, the structure of

the balance sheet is managed so that movements of interest rates on assets and
liabilities (adjusted for off-balance sheet hedges) are highly correlated and
produce an adequate level of earnings, even in periods of volatile interest
rates.
 In the management of interest rate risk, Northern Trust utilizes the following
measurement techniques: model simulation to determine the sensitivity of
earnings, economic value sensitivity of the balance sheet, and gap analysis.
These three techniques are complementary and are used in concert to provide a
more complete picture of interest rate risk.
 Model simulation is the primary tool used to measure the sensitivity of
earnings to interest rate changes. Using computer modeling techniques, Northern
Trust is able to measure the potential impact on earnings, assuming the
continuation of current balance sheet trends, different patterns of rate
movements, and specific changes in the relationships among various instruments
on and off the balance sheet. Northern Trust uses model simulation to measure
its earnings sensitivity relative to management's most likely interest rate
scenario. At December 31, 1996, this scenario assumed a gradual increase in
interest rates during 1997. The interest sensitivity is then tested by running
alternative scenarios above and below the most likely interest rate outcome. In
1996, this sensitivity calculation was always less than 3.5% of the annual
income before income taxes, using alternative scenarios based on a one
percentage point deviation from the rates assumed over a one year horizon. The
simulations do not anticipate management's actions to moderate the negative

consequences of interest rate deviations. Therefore, the simulations serve as
conservative estimates of interest rate risk.
 The second technique that is used to measure interest rate risk is the
analysis of the sensitivity of economic value of the balance sheet. The
economic value sensitivity analysis examines the market value impact of on- and
off-balance sheet positions to adverse interest rate movements. Northern Trust
strives to limit the economic value sensitivity of the balance sheet to an
acceptable level in the context of risk-return trade-offs.
 The third technique that is used to measure interest rate risk is gap
analysis. The calculation of the interest sensitivity gap is shown in the
following table, which measures the timing mismatches between assets and
liabilities. This interest sensitivity gap is determined by subtracting the
amount of liabilities from the volume of assets that reprice in a particular
time interval. A liability sensitive position results when more liabilities
than assets reprice or mature within a given period. Under this scenario, as
interest rates decline, increased net interest revenue will be generated.
Conversely, an asset sensitive position results when more assets than
liabilities reprice within a given period; in this instance, net interest
revenue would benefit from an increasing interest rate environment. The
financial impact of creating a liability or asset sensitive position depends on
the magnitude of actual changes in interest rates relative to the current
expectations of market participants.
 A variety of actions are used to implement interest risk management
strategies, including:
  . purchases of securities;
  . sales of securities that are classified as available
    for sale;
  . issuance of senior notes;
  . placing and taking Eurodollar time deposits; and
  . hedging with various types of derivative financial instruments.
 Northern Trust strives to use the most effective instrument for implementing
its interest risk management strategies, considering the costs, liquidity and
capital requirements of the various alternatives. For more detail regarding how
derivative financial instruments are used to implement interest risk management
strategies, refer to Note 20 on page 54.

LIQUIDITY RISK MANAGEMENT
The objective of liquidity risk management is to ensure that Northern Trust can
meet its cash flow requirements and to capitalize on business opportunities on
a timely and cost-effective basis. Management monitors the liquidity position
on a daily basis to ensure that funds are available at a minimum cost to meet
loan and deposit cash flows. The liquidity profile is also structured to ensure
that the capital needs of the Corporation and its banking subsidiaries are met.
Management maintains a detailed liquidity contingency plan designed to
adequately respond to dramatic changes in market conditions.
 Liquidity is secured by managing the mix of items on the balance sheet and
expanding potential sources of liquidity. The balance sheet sources of
liquidity include the short-term money market portfolio, unpledged available
for sale securities, maturing loans, and the ability to securitize a portion of
the loan portfolio. Further, liquidity arises from the diverse funding base and
the fact that a significant portion of funding comes from clients that have
other relationships with Northern Trust.
 A significant source of liquidity is the ability to draw funding from both
domestic and international markets. The Bank's senior long-term debt is rated
AA- by Standard & Poor's, Aa3 by Moody's Investors Service, and AA+ by Thomson
BankWatch. These ratings put The Northern Trust Company in the top tier of
United States banks.
 Northern Trust maintains a liquid balance sheet with loans representing 51% of
total assets. Further, at December 31, 1996, it had a significant liquidity
reserve on its balance sheet in the form of cash and due from banks, securities
available for sale, and money market assets, which in aggregate totaled $8.8
billion or 41% of total assets.
 The Corporation's uses of cash consist mainly of dividend payments to the
Corporation's common and preferred stockholders, the payment of principal and
interest to note holders, and purchases of its common stock. These requirements
are met largely by dividend payments from its subsidiaries, and by interest and
dividends earned on investment securities and money market assets. Bank
subsidiaries have the ability to pay dividends during 1997 equal to their 1997
eligible net profits plus $208.2 million. Bank subsidiary dividends are subject
to certain restrictions that are explained in Note 14 on page 49. The
Corporation's liquidity, defined as the amount of marketable assets in excess
of commercial paper, was strong at $102 million at year-end 1996. The cash
flows of the Corporation are shown in Note 28 on page 63. The Corporation also
has a $50 million back-up line of credit for its commercial paper issuance. The
Corporation's strong credit ratings allow it to access credit markets on
favorable terms.
 
CAPITAL MANAGEMENT
One of management's primary objectives is to maintain a strong capital position
to merit the confidence of clients, the investing public, bank regulators and
stockholders. A strong capital position helps Northern Trust withstand
unforeseen adverse developments and take advantage of profitable investment
opportunities when they arise. In 1996, common equity on average increased 13%
or $159 million reaching a record $1.4 billion at year-end, while total risk-
adjusted assets rose 15%. Total equity as of December 31, 1996 was $1.5 billion
including $120 million of auction rate preferred stock. The average dividend
rate declared on the $120 million of auction rate preferred stock was 4.00%
during 1996 versus 4.51% in 1995. In January 1996, the Corporation called for
redemption its $50 million Series E convertible preferred stock. Virtually all
of the holders elected to convert rather than redeem their preferred stock, and
in January the Corporation issued 2,396,744 shares of common stock in
connection with the conversion. The shares issued upon conversion were
previously reflected in the Corporation's fully diluted shares, so that
conversion had no impact on fully diluted net income per common share.
 During 1996 the Corporation purchased 4,096,956 of its own shares as part of
the buyback program authorized in 1994. In November, the Board of Directors
authorized an increase in the Corporation's buyback program so that the
Corporation may purchase, after December 31, 1996, up to 4.6 million shares.
 The Board of Directors increased the quarterly dividend by 16.1% to $.18 per
common share in November 1996. Over the last five years the common dividend has
increased 125%.
 At December 31, 1996, tier 1 capital was 8.2% and total capital was 11.9% of
risk-adjusted assets. These risk-based capital ratios are well above the
minimum requirements of 4.0% for tier 1 and 8.0% for total risk-based capital
ratios. Northern Trust's leverage ratio (tier 1 capital to fourth quarter
average assets) of 6.4% is also well above the regulatory requirement of 3.0%.
In addition, each of the subsidiary banks had a ratio of at least 7.8% for tier
1 capital, 10.8% for total risk-based capital, and 6.1% for the leverage ratio.
 On January 16, 1997, the Corporation further strengthened its capital ratios
with the issuance of $150 million of Floating Rate Capital Securities.

OPERATIONAL AND FIDUCIARY RISK MANAGEMENT
In providing banking and trust services, Northern Trust, in addition to
safekeeping and managing trust and corporate assets, processes cash and
securities transactions exceeding $105 billion on average each business day.
These activities expose Northern Trust to operational and fiduciary risk.
Controls over such processing activities are closely monitored to safeguard the
assets of Northern Trust and its clients. However, from time to time Northern
Trust has suffered losses related to these risks and there can be no assurance
that such losses will not occur in the future.
 Operational risk is the risk of unexpected losses attributable to human error,
systems failures, fraud, or inadequate internal controls and procedures. This
risk is mitigated through a system of internal controls that are designed to
keep operating risk at appropriate levels in view of Northern Trust's corporate
standards and the risks inherent in the markets in which Northern Trust
operates. The system of internal controls includes policies and procedures that
require the proper authorization, approval, documentation, and monitoring of
transactions. Each business unit is responsible for complying with corporate
policies and external regulations applicable to the unit, and is responsible
for establishing specific procedures to do so. Northern Trust's internal
auditors monitor the overall effectiveness of the system of internal controls
on an ongoing basis.
 Fiduciary risk is the risk of loss that may occur as a result of breaching a
fiduciary duty to a client. To limit this risk, the Trust Investment Committee
establishes corporate policies and procedures to ensure that obligations to
clients are discharged faithfully and in compliance with applicable legal and
regulatory requirements. These policies and procedures provide guidance and
establish standards related to the creation, sale, and management of investment
products, trade execution, and counterparty selection. Business units have the
primary responsibility for adhering to the policies and procedures applicable
to their businesses.

LINES OF BUSINESS
The results for the major business units are presented in order to promote a
greater understanding of their financial performance and strategic direction.
The information, presented on an internal management reporting basis, is
derived from internal accounting systems that support the strategic objectives
and management structure. Consequently, the results are not necessarily
comparable with similar information for other financial institutions.
 Management has developed accounting systems to allocate revenue and expenses
related to each line of business, as well as certain corporate support
services, worldwide operations and systems development expenses. The systems
also incorporate processes for allocating assets, liabilities and the
applicable interest income and expense. Equity is primarily allocated using the
federal regulatory risk-based capital guidelines, coupled with management's
judgment of the operational risks inherent in the business. Allocations of
capital and certain corporate expenses may not be representative of the levels
that would be required if the businesses were independent entities.
 
CORPORATE AND INSTITUTIONAL SERVICES. Corporate and Institutional Services
includes corporate trust, investment management and securities lending
services, commercial banking activities of the Bank, treasury management
services, foreign exchange activities, the London and Singapore branches, NTRC,
NTGA and Northern Futures Corporation.
 
PERSONAL FINANCIAL SERVICES. Personal Financial Services encompasses personal
trust and investment management services, estate administration, personal
banking and mortgage and other lending to individuals and middle market
companies. This business unit also includes the commercial banking activities
of the affiliate banks and the activities of Northern Trust Securities, Inc.
 
CORPORATE AND OTHER. Corporate and Other includes the Bank's Treasury
Department and other corporate items, including the impact of long-term debt,
preferred equity, holding company investments, and corporate operating
expenses. The decline in noninterest expenses from 1995 to 1996 reflects
decreases in severance costs and pension settlement charges, and lower salary
and benefit expenses resulting from staff reductions in corporate support
areas. Noninterest income for 1994 included the net gain of $28.5 million from
the sale of the interest in BSS. 1994 noninterest expenses included non-
recurring charges totaling $23.2 million. Of the $23.2 million, $13.6 million
resulted from the trade-in and the sale and leaseback of mainframe computer
equipment and the write-down of older trust-related software, and $9.6 million
from pension settlement charges.
 The following table reflects the earnings contribution of Northern Trust's
lines of business for the years ended December 31, 1996, 1995 and 1994 on the
basis described above.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. ACCOUNTING POLICIES--The consolidated financial statements have been
prepared in conformity with generally accepted accounting principles and
reporting practices prescribed for the banking industry. A description of the
significant accounting policies follows:
 A. BASIS OF PRESENTATION. The consolidated financial statements include the
accounts of Northern Trust Corporation (Corporation) and its wholly owned
subsidiary The Northern Trust Company (Bank) and their wholly owned
subsidiaries. Throughout the notes, the term ""Northern Trust'' refers to
Northern Trust Corporation and subsidiaries. Significant intercompany balances
and transactions have been eliminated in consolidation. The consolidated
statement of income includes results of acquired and pooled subsidiaries from
the dates of acquisition.
 B. NATURE OF OPERATIONS. The Corporation is a bank holding company whose
principal subsidiary is the Chicago-based Bank. The Corporation also owns banks
in Arizona, California, Florida and Texas, and various other nonbank
subsidiaries, including a brokerage firm, a futures commission merchant, an
international investment consulting firm and a retirement services company. The
Corporation also owned three other Illinois banks which were merged into the
Bank on February 29, 1996. Northern Trust generates the majority of its
revenues from its two primary business units, Corporate and Institutional
Services (C&IS) and Personal Financial Services (PFS).
 The C&IS unit provides trust and custody-related services in the United States
and foreign markets to corporations and institutions; a full range of
commercial banking services to large domestic corporations and financial
institutions; treasury management services to meet the needs of major
corporations and financial institutions; and foreign exchange services for
global custody clients and Northern Trust's own account.
 The PFS unit provides personal trust, investment management, estate
administration, personal banking and mortgage lending services, and also
provides commercial banking services to middle market companies. These services
are delivered through the Bank and the network of subsidiaries in Arizona,
California, Florida and Texas.
 C. USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the consolidated financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 D. FOREIGN CURRENCY TRANSLATION. Foreign currency asset and liability accounts
of overseas branches are translated at current rates of exchange, except for
buildings and equipment which are translated at rates in effect at the date of
acquisition. Income and expense accounts are translated at month-end rates of
exchange.
 Foreign exchange trading positions are valued daily at prevailing market
rates. Gains and losses on trading positions and on positions entered into to
hedge foreign denominated investments are recognized currently in other
operating income. Unrealized gains on trading positions are reported as other
assets and unrealized losses are reported as other liabilities in the
consolidated balance sheet. Gains and losses on foreign currency positions that
were entered into to hedge specific, firm foreign currency obligations are
deferred and recognized in income over the life of the underlying asset or
liability or as the underlying expense or commitment is incurred.
 E. SECURITIES. Securities Available for Sale consist of debt and equity
securities that are not intended to be held to maturity and are not held for
trading. Securities available for sale are reported at fair value, with
unrealized gains and losses credited or charged, net of the tax effect,
directly to stockholders' equity. Realized gains and losses on securities
available for sale are determined on a specific identification basis and are
reported in the consolidated statement of income as investment security gains
and losses.
 Securities Held to Maturity consist of debt securities that management intends
to, and Northern Trust has the ability to, hold until maturity. Such securities
are reported at cost, adjusted for amortization of premium and accretion of
discount.
 Securities Held for Trading are stated at fair value. Realized and unrealized
gains and losses on securities held for trading are reported in the
consolidated statement of income under security commissions and trading income.
 F. INTEREST RISK MANAGEMENT INSTRUMENTS. Interest risk management instruments
include interest rate swap contracts, futures contracts, options and similar
contracts. Northern Trust is a party to various interest risk management
instruments to meet the interest risk management needs of its clients, as part
of its trading activity for its own account and as part of its asset/liability
management activities. Unrealized gains and receivables on interest risk
management instruments are reported as other assets and unrealized losses and
payables are reported as other liabilities in the consolidated balance sheet.
 Interest risk management instruments entered into to meet clients' interest
risk management needs or for trading purposes are carried at fair value, with
realized and unrealized gains and losses included in security commissions and
trading income.
 Interest risk management instruments entered into to hedge specifically
identified existing assets and liabilities or anticipated transactions are
accounted for under the accrual method or fair value method, as described
below, if they effectively change the cash flows of the hedged item and the
hedged item exposes Northern Trust to interest rate risk.

 ACCRUAL METHOD. Under this method, the accrued interest income or expense on
the interest risk management instrument is recognized as a component of the
interest income or expense of the hedged item. There is no recognition of
unrealized gains and losses on the instruments in the balance sheet. Realized
gains and losses on futures contracts are deferred and recognized as an
adjustment to interest income or expense over the life of the hedged item.
 FAIR VALUE METHOD. The fair value method is used in those cases where the
hedged items are carried at fair value or the lower of cost or fair value.
Under this method, the related interest risk management instruments are carried
at fair value. Unrealized gains and losses on the interest risk management
instruments are recognized consistent with the method of accounting for the
hedged items. For example, unrealized gains and losses on interest rate swaps
used to hedge available for sale securities are reported in stockholders'
equity, net of applicable taxes. Accrued interest income and expense on swaps
used to hedge available for sale securities is reported in interest income on
securities.
 G. LOANS AND LEASES. Loans that are held to maturity are reported at the
principal amount outstanding, net of unearned income. Residential real estate
loans classified as held for sale are reported at the lower of aggregate cost
or market value. Interest income on loans is recorded on an accrual basis
until, in the opinion of management, there is a question as to the ability of
the debtor to meet the terms of the contract, or when interest or principal is
more than 90 days past due and the loan is not well-secured and in the process
of collection. At the time a loan is placed on nonaccrual status, interest
accrued but not collected is reversed against interest income of the current
period. Loans are returned to accrual status when factors indicating doubtful
collectibility no longer exist. Interest collected on nonaccrual loans is
applied to principal unless, in the opinion of management, collectibility of
principal is not in doubt.
 Premiums and discounts on loans are recognized as an adjustment of yield by
the interest method based on the contractual terms of the loan. Commitment fees
that are considered to be an adjustment to the loan yield, loan origination
fees and certain direct costs are deferred and accounted for as an adjustment
of the yield.
 Unearned lease income from direct financing and leveraged leases is recognized
using the interest method. This method provides a constant rate of return on
the unrecovered investment over the life of the lease.
 H. RESERVE FOR CREDIT LOSSES. The reserve for credit losses is established
through provisions for credit losses charged to income. Loans, leases and other
extensions of credit deemed uncollectible are charged to the reserve.
Subsequent recoveries, if any, are credited to the reserve. The loan and lease
portfolio and other extensions of credit are regularly reviewed to evaluate the
adequacy of the reserve for credit losses. The impact of economic conditions on
the creditworthiness of borrowers is given major consideration in determining
the adequacy of the reserve. Credit loss experience, changes in the character
and size of the loan portfolio, the estimated value of impaired loans compared
to their recorded investment, and management's judgment are other factors used
in assessing the overall adequacy of the reserve for credit losses and the
resulting provision for credit losses. Actual losses may vary from current
estimates and the amount of the provision may be either greater than or less
than actual net charge-offs.
 I. MORTGAGE SERVICING RIGHTS. Effective January 1, 1996, Northern Trust
adopted Statement of Financial Accounting Standards (SFAS) No. 122,
""Accounting for Mortgage Servicing Rights.'' This statement requires that
mortgage servicing rights be capitalized as a separate asset when purchased or
when acquired through the origination of mortgage loans that are subsequently
sold with the servicing rights retained. The servicing rights are included in
other assets and are amortized as an offset to other operating income over
their estimated life. SFAS No. 122 also requires that servicing rights be
evaluated for impairment based on their fair value. For purposes of measuring
impairment, Northern Trust stratifies its servicing rights by loan type and
interest rate. Fair value is determined considering market prices for similar
assets. Impairment losses are recognized by establishing a valuation allowance
for each stratum to the extent that the unamortized carrying value of servicing
rights in the stratum exceeds fair value. Changes in the valuation allowances
are recorded in other operating income.
 J. FEES ON STANDBY LETTERS OF CREDIT AND PARTICIPATIONS IN BANKERS
ACCEPTANCES. Fees on standby letters of credit are recognized in other
operating income on the straight-line method over the lives of the underlying
agreements. Commissions on bankers acceptances are recognized in other
operating income when received.
 K. BUILDINGS AND EQUIPMENT. Buildings and equipment owned are carried at
original cost less accumulated depreciation. The charge for depreciation is
computed on the straight-line method based on the following range of lives:
buildings--10 to 30 years; equipment--4 to 10 years; and leasehold
improvements--1 to 15 years. Leased properties meeting certain criteria are
capitalized and amortized using the straight-line method over the lease period.
 L. OTHER REAL ESTATE OWNED (OREO). OREO is comprised of commercial and
residential real estate properties acquired in partial or total satisfaction of
problem loans.
 OREO assets are carried at the lower of cost or fair value. Losses identified
at the time of acquisition of such properties are charged against the reserve
for credit losses. Subsequent write-downs that may be required to the carrying
value of these assets and losses realized from asset sales are charged to other
operating expenses. Gains realized from the sale of OREO are included in other
operating income.
 
                                                                              41

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

 M. INTANGIBLE ASSETS. Goodwill, arising from the excess of purchase price over
the fair value of net assets of acquired subsidiaries, is being amortized using
the straight-line method over periods benefiting, ranging primarily from
fifteen to twenty years.
 SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of," establishes accounting standards for the
impairment of such assets, certain identifiable intangibles, and goodwill
related to those assets to be held and used and for similar assets and certain
identifiable intangibles to be disposed of. This statement requires that those
assets held and used be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount may not be recoverable; and
that those to be disposed of be reported at the lower of carrying amount or
fair value less cost to sell, with certain exceptions. This statement was
adopted January 1, 1996. No adjustments to the carrying value of long-lived
assets were required as a result of adopting this statement.
 Other purchased intangible assets arising from acquisitions are amortized
using various methods over the estimated lives of the assets. Software is being
amortized using the straight-line method over the estimated useful life of the
asset, ranging from three to seven years.
 N. TRUST ASSETS AND FEES. Assets held in fiduciary or agency capacities are
not included in the consolidated balance sheet, since such items are not assets
of Northern Trust. Income from trust activities is recorded on the accrual
basis.
 O. TRUST SECURITY SETTLEMENT RECEIVABLES. These receivables represent other
items in the process of collection presented on behalf of trust clients.
 P. INCOME TAXES. In accordance with SFAS No. 109, ""Accounting for Income
Taxes,'' an asset and liability approach to accounting for income taxes is
followed. The objective is to recognize the amount of taxes payable or
refundable for the current year, and to recognize deferred tax assets and
liabilities resulting from temporary differences between the amounts reported
in the financial statements and the tax bases of assets and liabilities. The
measurement of tax assets and liabilities is based on enacted tax laws and
applicable tax rates.
 Q. CASH FLOW STATEMENTS. Cash and cash equivalents have been defined as those
amounts included in the consolidated balance sheet as ""Cash and Due from
Banks.''
 
2. RECLASSIFICATIONS--Certain reclassifications have been made to prior
periods' consolidated financial statements to place them on a basis comparable
with the current period's consolidated financial statements.
 
3. SECURITIES--SECURITIES AVAILABLE FOR SALE. Realized gross security gains and
losses, which were included in the consolidated statement of income, totaled
$1.5 million and $1.1 million, respectively in 1996. Of the $1.5 million in
gains in 1996, $1.0 million was related to the sale of securities classified as
available for sale. The remaining $.5 million resulted when held to maturity
securities were called at a premium. Realized gross security losses in 1996
resulted entirely from the sale of securities classified as available for sale.
Realized gross security gains and losses totaled $1.0 million and none,
respectively, in 1995. Of the $1.0 million in gains in 1995, $.1 million was
related to the sale of securities classified as available for sale. The
remaining $.9 million resulted when held to maturity securities were called at
a premium. Realized gross security gains and losses in 1994 totaled $.2 million
and $.3 million, respectively, all of which were related to securities
available for sale.
 The following tables summarize the amortized cost, fair values and remaining
maturities of securities available for sale.

AGREEMENTS TO REPURCHASE--Securities purchased under agreements to resell and
securities sold under agreements to repurchase are recorded at the amounts at
which the securities were acquired or sold plus accrued interest. To minimize
any potential credit risk associated with these transactions, the fair value of
the securities purchased or sold is continuously monitored, limits are set on
exposure with counterparties, and the financial condition of counterparties is
regularly assessed. It is Northern Trust's policy to take possession of
securities purchased under agreements to resell. The following tables summarize
information related to securities purchased under agreements to resell and

LINES OF CREDIT. The Corporation currently maintains commercial paper back-up
facility lines of credit with three banks totaling $50 million. The facility
was amended in 1995. The current termination date is November 2000, with an
optional one-year extension beyond that. The commitment fee is determined by a
pricing matrix that is based on the long-term senior debt ratings of the
Corporation. Currently, the annual fee is 1/10 of 1% of the commitment. There
were no borrowings under commercial paper back-up facilities during 1996 or
1995.
 
GUARANTEED PREFERRED BENEFICIAL INTERESTS IN CORPORATION'S JUNIOR SUBORDINATED
DEFERRABLE INTEREST DEBENTURES. On January 16, 1997, the Corporation issued
$150 million of Floating Rate Capital Securities, Series A (Series A Capital
Securities) through NTC Capital I, a wholly owned statutory business trust. The
Corporation unconditionally guarantees all of the obligations of NTC Capital I.
Proceeds of $148.5 million which was net of discount, were invested by NTC
Capital I in $150 million principal amount of the Corporation's Floating Rate
Junior Subordinated Deferrable Interest Debentures, Series A (Subordinated
Debentures), with a stated maturity date of January 15, 2027. The holders of
the Series A Capital Securities are entitled to receive preferential cumulative
cash distributions quarterly in arrears (based on the liquidation amount of
$1,000 per Capital Security) at an interest rate equal to 3-Month LIBOR plus
0.52%, which is the same as the interest rate on the Subordinated Debentures.
Subject to certain exceptions, the Corporation has the right to defer payment
of interest on the Subordinated Debentures at any time or from time to time for
a period not exceeding 20 consecutive quarterly periods provided that no
extension period may extend beyond the stated maturity date. If interest is
deferred on the Subordinated Debentures, distributions on the Series A Capital
Securities will also be deferred and the Corporation will not be permitted,
subject to certain exceptions, to pay or declare any cash distributions with
respect to the Corporation's capital stock or debt securities that rank the
same as or are junior to the Subordinated Debentures, until all past due
distributions are paid. The Subordinated Debentures are unsecured and
subordinated to substantially all of the Corporation's existing indebtedness.
 Series A Capital Securities are subject to mandatory redemption in whole or in
part upon the repayment of the Subordinated Debentures. The Subordinated
Debentures are redeemable prior to maturity at the option of the Corporation,
subject to regulatory approval, on or after January 15, 2007 in whole or in
part or within 90 days following certain defined tax or regulatory capital
treatment changes, at a price equal to the principal amount plus accrued and
unpaid interest.

 SERIES C--In 1987, 600 shares of Auction Rate Preferred Stock (APS) Series C
were issued, with a $100,000 per share stated value. Dividends on the shares of
APS are cumulative. Rates are determined every 49 days by Dutch auction unless
the Corporation fails to pay a dividend or redeem any shares for which it has
given notice of redemption, in which case the dividend rate will be set at 175%
of the 60-day "AA" Composite Commercial Paper Rate. The dividend rate in any
auction will not exceed a percentage determined by the prevailing credit rating
of the APS. The current maximum dividend rate is 120% of the 60-day "AA"
Composite Commercial Paper Rate. No dividends other than dividends payable in
junior stock, such as Common Stock, may be paid on Common Stock until full
cumulative dividends on the APS have been paid. The average rate for this issue
as declared during 1996 was 4.04%. The shares of APS are redeemable at the
option of the Corporation, in whole or in part, on any Dividend Payment Date at
$100,000 per share, plus accrued and unpaid dividends.
 SERIES D--In 1990, 600 shares of Flexible Auction Rate Cumulative Preferred
Stock Series D (FAPS) were issued with a $100,000 per share stated value. Each
dividend period shall contain 49 days (the "Short-Term Dividend Period") or a
number of days greater than 49 days (as selected by the Term Selection Agent)
which is divisible by seven (the "Long-Term Dividend Period"). Rates for each
dividend period are determined by Dutch auction unless the Corporation fails to
pay the full amount of any dividend or redemption. The dividend rate in any
auction will not exceed a percentage (currently 125%), determined by the
prevailing credit rating of the FAPS, of the 60-day "AA"
 
                                                                              47

Composite Commercial Paper Rate or the Reference Rate, which rate is the
Composite Commercial Paper Rate or the Treasury Rate, as appropriate for the
length of each Short-Term or Long-Term Dividend Period, respectively. If the
Corporation fails to pay the full amount of any dividend or redemption, each
dividend period thereafter (until auctions are resumed) will be a Short-Term
Dividend Period and the dividend rate will be 250% of the 60-day "AA" Composite
Commercial Paper Rate; additional dividends will accrue for the balance of any
Long-Term Dividend Period in which such a failure to pay occurs. No dividends
other than dividends payable in junior stock, such as Common Stock, may be paid
on Common Stock until full cumulative dividends on the FAPS have been paid. The
average rate for this issue as declared during 1996 was 3.97%. The shares of
FAPS are redeemable at the option of the Corporation, in whole or in part, at
$100,000 per share plus accrued and unpaid dividends.
 SERIES E--On January 5, 1996, the Corporation called for redemption its
outstanding 6.25% Cumulative Convertible Preferred Stock Series E. The Series E
was sold to the public in the form of 1,000,000 Depositary Shares, each
representing one-twentieth of a share of the Series E Preferred Stock (equal to
50,000 preferred shares). In January 1996, 994,737 of the total 1,000,000
Depositary Shares were converted at the option of the holders at a conversion
price of $41.50 into 1,198,372 (2,396,744 shares on a post-split basis) shares
of the Corporation's common stock. The conversion resulted in fractions of
shares for which the Corporation paid cash. The remaining 5,263 Depositary
Shares were redeemed on January 26, 1996, for cash at a redemption price of
$52.8038 per Depositary Share.
 
PREFERRED STOCK PURCHASE RIGHTS. In 1989, the Board of Directors of the
Corporation declared a dividend distribution of one Preferred Stock Purchase
Right on each outstanding share of the Corporation's common stock to the
stockholders of record on October 31, 1989. The Rights are subject to anti-
dilution provisions, and each Right is now exercisable for one-sixth of one-
hundredth of a share of Series A Junior Participating Preferred Stock at an
exercise price of $41.67 for each such fractional share. The Rights are
evidenced by the common stock certificates and are not exercisable or
transferable apart from the common stock until twenty days after a person or
group acquires 15 percent or more of the Corporation's voting power or
announces a tender or exchange offer which could result in ownership of 25
percent or more of the voting power. Shares of the Participating Preferred
Stock purchasable upon exercise of the Rights will not be redeemable.
 In the event that a person or group acquires 25 percent or more of the
Corporation voting power or if the Corporation merges or engages in certain
self-dealing transactions with a 15 percent or more stockholder, each Right
will entitle the holder, other than such person or group in certain
circumstances, to purchase that number of shares of surviving company common
stock which at the time of the transaction would have a market value of twice
the exercise price of the Right.
 The Rights do not have voting rights and are redeemable at the option of the
Corporation at a price of one cent per Right at any time prior to the close of
business on the 20th day following publication of the acquisition of 15 percent
or more of the voting power by a person or group. Unless earlier redeemed, the
Rights will expire on October 31, 1999.
 
COMMON STOCK. In November, 1996, the Corporation declared a two-for-one split
of its common stock, to be effected by means of a 100% stock distribution. One
share for each share held by shareholders of record on December 2, 1996 was
distributed on December 9, 1996.
 Also in November, 1996, the Corporation announced that it increased its common
stock buyback authorization by approximately 4.2 million shares, thus allowing
the purchase after December 31, 1996 of up to an aggregate of 4.6 million
shares of the Corporation's common stock. The shares may be repurchased from
time to time in open market purchases, and the shares would be used primarily
for management incentive plans and other corporate purposes.

 Northern Trust has state carryforwards which are available to offset future
state tax return liabilities. As of December 31, 1996, there were state net
operating loss and tax credit carryforwards of $22.6 million and $2.4 million,
respectively. The carryforwards are subject to various limitations imposed by
tax law.
 
13. NET INCOME PER COMMON SHARE COMPUTATIONS Per share data and average shares
outstanding have been restated for all periods presented to give effect to the
two-for-one common stock split effected by means of a 100% stock distribution
on December 9, 1996.
 Primary net income per common share is computed by dividing net income, after
deduction of the preferred stock dividends, by the daily average number of
common and common equivalent shares outstanding. Common equivalent shares are
based on outstanding stock options and common stock awards under the Amended
1992 and the Amended Incentive Stock Plans and other stock-based plans
associated with acquisitions.
 Fully diluted net income per common share in 1995 and 1994 assumed, in
addition to the above, the conversion of the Cumulative Convertible Preferred
Stock Series E.
 
14. RESTRICTIONS ON SUBSIDIARY DIVIDENDS AND LOANS OR ADVANCES--Provisions of
state and federal banking laws restrict the amount of dividends that can be
paid to the Corporation by its banking subsidiaries. Under applicable state and
federal laws, no dividends may be paid in an amount greater than the net
profits then on hand, subject to other applicable provisions of law. In
addition,
 
                                                                              49

<PAGE>
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

prior approval of the relevant federal banking regulator is required if
dividends declared by any of the Corporation's banking subsidiaries in any
calendar year will exceed its net profits (as defined) for that year, combined
with its retained net profits for the preceding two years.
 Based on these regulations, the Corporation's banking subsidiaries, without
regulatory approval, could declare dividends during 1997 equal to their 1997
eligible net profits (as defined) plus $208.2 million. The ability of each
banking subsidiary to pay dividends to the Corporation may be further
restricted as a result of regulatory policies and guidelines relating to
dividend payments and capital adequacy.
 State and federal laws limit the transfer of funds by a banking subsidiary to
the Corporation and certain of its affiliates in the form of loans or
extensions of credit, investments or purchases of assets. Transfers of this
kind to the Corporation or a nonbanking subsidiary by a banking subsidiary are
each limited to 10% of the banking subsidiary's capital and surplus with
respect to each affiliate and to 20% in the aggregate, and are also subject to
certain collateral requirements. These transactions, as well as other
transactions between a banking subsidiary and the Corporation or its
affiliates, must also be on terms substantially the same as, or at least as
favorable as, those prevailing at the time for comparable transactions with
non-affiliated companies or, in the absence of comparable transactions, on
terms, or under circumstances, including credit standards, that would be
offered to, or would apply to, non-affiliated companies.
 
15. OTHER OPERATING INCOME--Included in the 1994 results is a $28.5 million
pretax gain on the sale of an investment in Banque Scandinave en Suisse (BSS),
net of approximately $6.0 million in ancillary and other sale-related
transition costs associated with the transfer of custody accounts from BSS to
the Bank's London Branch.
 
16. OTHER OPERATING EXPENSES--The components of other operating expenses were

 Software, goodwill and other intangible assets are included in other assets in
the consolidated balance sheet. Software totaled $133.8 million at December 31,
1996 and $129.8 million at December 31, 1995. Goodwill totaled $66.5 million at
December 31, 1996 and $65.5 million at December 31, 1995. Other intangibles
totaled $39.4 million at December 31, 1996 and $41.3 million at December 31,
1995.
 
17. PENSION AND OTHER EMPLOYEE BENEFITS--PENSION. A noncontributory qualified
pension plan covers substantially all employees. The plan provides benefits for
normal and early retirement, benefits for vested employees and, under certain
circumstances, survivor benefits in the event of death. Benefits are based on
the employees' years of service and their five highest consecutive years of
compensation. The proportion of average compensation paid as a pension benefit
is determined by length of service. Contributions to the plan satisfy or exceed
the minimum funding requirements of ERISA. Certain retiree death benefits are
funded through the pension plan and the related cost is included as pension
expense. Assets held by the plan consist primarily of listed stocks and
corporate bonds.
 Northern Trust also maintains a noncontributory nonqualified pension plan for
participants whose retirement benefit payments under the qualified plan are
expected to exceed the limits imposed by federal tax law. Northern Trust has a
nonqualified trust, referred to as a "Rabbi" trust, to fund benefits in excess
of those permitted in certain of its qualified plans. The primary purpose of
the trust is to fund nonqualified retirement benefits. This arrangement offers
certain officers a degree of assurance for payment of benefits in excess of
those permitted in the related qualified plans. The assets remain subject to
the claims of creditors and are not the property of the employees. Therefore,
they are accounted for as corporate assets and are included in other assets in
the consolidated balance sheet.

 Pension expense for 1994 was $7.7 million and $3.1 million for the qualified
and nonqualified plans, respectively. In 1996, the service benefit formula and
survivor annuity provisions were amended and the mortality assumptions were
changed for the qualified and nonqualified plans. The changes reduced total
1996 pension expense by $1.1 million.
 Total assets in the "Rabbi" Trust primarily related to the nonqualified
pension plan at December 31, 1996 and 1995 amounted to $10.3 million, and $8.7
million, respectively.
 A pension plan is also maintained for the London Branch employees. At December
31, 1996, the fair value of assets and the projected benefit obligation totaled
approximately $7.8 million and $9.1 million, respectively. At December 31,
1995, the fair value of assets and the projected benefit obligation were $7.1
million and $8.1 million, respectively. Pension expense for 1996 and 1995 was
$1.1 million and $.6 million, respectively.
 
THRIFT INCENTIVE PLAN. The Corporation and its subsidiaries have a defined
contribution Thrift Incentive Plan covering substantially all employees. The
corporate contribution is contingent upon the level of employee contribution
and meeting a predefined earnings target for the year. The maximum corporate
contribution was equal to 4% of an employee's salary in 1996 and 5% in each of
the years 1995 and 1994. The estimated contribution to this plan is charged to
pension and other employee benefits and totaled $8.0 million in 1996, $11.3
million in 1995 and $10.6 million in 1994.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

EMPLOYEE STOCK OWNERSHIP PLAN (ESOP). A leveraged ESOP in which substantially
all employees of Northern Trust are eligible to participate was established in
1989. Under the original terms of the ESOP, the shares were to be allocated
over ten years. In 1996, the terms of the ESOP were amended. The original
maturity of the ESOP-related debt was effectively extended by an additional
three years through financing provided by the Corporation and the remaining
ESOP shares are being allocated over the six year period ending December 31,
2001. The Corporation will make an additional contribution of $5.4 million in
cash or shares of common stock in each of the years 2002 and 2003.
 Dividends paid on unallocated shares held in the ESOP Trust are used for debt
service on the ESOP notes. Compensation expense is accounted for based
primarily on the amount of cash paid by Northern Trust to the ESOP for
principal payments on the ESOP notes. Of the original 9 million shares in the
ESOP Trust, 6,750,300 shares have been allocated as of December 31, 1996. The
ESOP shares not yet allocated to individual accounts are treated as deferred
compensation and accounted for as a reduction of stockholders' equity.
 The following table presents information related to the ESOP.

OTHER POSTRETIREMENT BENEFITS. Northern Trust maintains an unfunded
postretirement health care plan. Employees retiring under the provisions of The
Northern Trust Pension Plan may be eligible for postretirement health care
coverage. These benefits are provided either through an indemnity plan, subject
to deductibles, co-payment provisions and other limitations or through health
maintenance organizations. The provisions may be changed at the discretion of
Northern Trust, which also reserves the right to terminate these benefits at
any time.
 The following tables set forth the plan status at December 31 and the net
periodic postretirement
benefit cost of the domestic postretirement health care plan for 1996 and 1995.
The transition obligation at January 1, 1993 is being amortized to expense over
a twenty year period.

 Postretirement health care expense for 1994 was $5.1 million. In 1996, the
cost sharing provisions of the plan were amended and resulted in a reduction in
1996 expense of $1.8 million.
 For measurement purposes, a 10.8% annual increase in the cost of covered health
care benefits was assumed for 1997. This rate is assumed to decrease gradually
to 5.6% in 2021 and remain at that level thereafter. The health care cost trend
rate assumption has a significant effect on the amounts reported. For example,
increasing the assumed health care trend rate by one percentage point in each
year would increase the accumulated postretirement benefit obligation for the
postretirement health care plan as of December 31, 1996 by approximately $1.8
million, and the aggregate of the service and interest cost components of the
1996 net periodic postretirement benefit cost by $.4 million. The weighted
average discount rate used in determining the accumulated postretirement benefit
obligation was 7.50% at December 31, 1996 and 1995.
 
18. CONTINGENT LIABILITIES--Because of the nature of its activities, Northern
Trust is subject to pending and threatened legal actions that arise in the
normal course of business. In the judgment of management, after consultation
with legal counsel, none of the litigation to which the Corporation or any of
its subsidiaries is a party will have a material effect, either individually or
in the aggregate, on the consolidated financial position or results of
operations.

19. FAIR VALUE OF FINANCIAL INSTRUMENTS--SFAS No. 107, ""Disclosures About Fair
Value of Financial Instruments,'' requires disclosure of the estimated fair
value of certain financial instruments. Considerable judgment is required to
interpret market data when computing estimates of fair value. Accordingly, the
estimates presented are not necessarily indicative of the amounts Northern
Trust could have realized in a market exchange.
 The information provided below should not be interpreted as an estimate of the
fair value of Northern Trust since the disclosures, in accordance with SFAS No.
107, exclude the values of nonfinancial assets and liabilities, as well as a
wide range of franchise, relationship, and intangible values, which are
integral to a full assessment of the consolidated financial position.
 The use of different assumptions and/or estimation methods may have a material
effect on the computation of estimated fair values. Therefore, comparisons
between Northern Trust's disclosures and those of other financial institutions
may not be meaningful.
 The following methods and assumptions were used in estimating the fair values
of the financial instruments:
 SECURITIES. Fair values of securities were based on quoted market values, when
available. If quoted market values were not available, fair values were based
on quoted market values for comparable instruments.
 LOANS (NOT INCLUDING LEASE FINANCING RECEIVABLES). The fair values of one-to-
four family residential mortgages were based on quoted market prices of similar
loans sold in conjunction with securitization transactions, adjusted for
differences in loan characteristics. The fair values of the remainder of the
loan portfolio were estimated using a discounted cash flow method in which the
discount rate used was the rate at which Northern Trust would have originated
the loan had it been originated as of the financial statement date, giving
effect to current economic conditions on loan collectibility.
 SAVINGS CERTIFICATES, OTHER TIME AND FOREIGN OFFICES TIME DEPOSITS, AND SENIOR
NOTES. The fair values of these instruments were estimated using a discounted
cash flow method that incorporated market interest rates.
 NOTES PAYABLE. Fair values were based on quoted market prices, when available.
If quoted market prices were not available, fair values were based on quoted
market prices for comparable instruments.
 OFF-BALANCE SHEET FINANCIAL INSTRUMENTS. The fair values of commitments and
letters of credit represent the amount of unamortized fees on these
instruments. The fair values of all other off-balance sheet financial
instruments were estimated using market prices, pricing models, or quoted
market prices of financial instruments with similar characteristics.
 FINANCIAL INSTRUMENTS VALUED AT CARRYING VALUE. Due to their short maturity,
the respective carrying values of certain on-balance sheet financial
instruments approximated their fair values. These financial instruments include
cash and due from banks; money market assets; customers' acceptance liability;
trust security settlement receivables; federal funds purchased; securities sold
under agreements to repurchase; commercial paper; other borrowings; and
liability on acceptances.
 The fair values required to be disclosed for demand, savings, and money market
deposits pursuant to SFAS No. 107 must equal the amounts disclosed in the
consolidated balance sheet.
 FAIR VALUES OF ON-BALANCE SHEET FINANCIAL INSTRUMENTS. The following table
summarizes the fair values of on-balance sheet financial instruments.

20. OFF-BALANCE SHEET FINANCIAL INSTRUMENTS--
 A. COMMITMENTS AND LETTERS OF CREDIT. Northern Trust, in the normal course of
business, enters into various types of commitments and issues letters of credit
to meet the liquidity and credit enhancement needs of its clients. Credit risk
is the principal risk associated with these instruments. The contractual
amounts of these instruments represent the credit risk should the instrument be
fully drawn upon and the client default. To control the credit risk associated
with entering into commitments and issuing letters of credit, Northern Trust
subjects such activities to the same credit quality and monitoring controls as
its lending activities.
 Commitments and letters of credit consist of the following:
 LEGALLY BINDING COMMITMENTS TO EXTEND CREDIT generally have fixed expiration
dates or other termination clauses. Since a significant portion of the
commitments are expected to expire without being drawn upon, the total
commitment amount does not necessarily represent future loans or liquidity
requirements.
 PARTICIPATIONS IN BANKERS ACCEPTANCES obligate Northern Trust, in the event of
default by the counterparty, to reimburse the holder of the acceptance an
amount equal to its participation in the acceptance.
 COMMERCIAL LETTERS OF CREDIT are instruments issued by Northern Trust on
behalf of its clients that authorize a third party (the beneficiary) to draw
drafts up to a stipulated amount under the specified terms and conditions of
the agreement. Commercial letters of credit are issued primarily to facilitate
international trade.
 STANDBY LETTERS OF CREDIT obligate Northern Trust to meet certain financial
obligations of its clients, if, under the contractual terms of the agreement,
the clients are unable to do so. These instruments are primarily issued to
support public and private financial commitments, including commercial paper,
bond financing, initial margin requirements on futures exchanges and similar
transactions.
 The following table shows the contractual amounts of commitments and letters
of credit.

 B. RISK MANAGEMENT INSTRUMENTS. These instruments include foreign exchange
contracts, foreign currency futures contracts, and various interest risk
management instruments.

Northern Trust Corporation
<PAGE>
 
 Northern Trust is a party to various risk management instruments that are used
in the normal course of business to meet the risk management needs of its
clients; as part of its trading activity for its own account; and as part of
its asset/liability management activities. The major risk associated with these
instruments is that interest or foreign exchange rates could change in an
unanticipated manner, resulting in higher interest costs or a loss in the
underlying value of the instrument. These risks are mitigated by establishing
limits for risk management positions, monitoring the level of actual positions
taken against such established limits, monitoring the level of any interest
rate sensitivity gaps created by such positions, and by using hedging
techniques. When establishing position limits, market liquidity and volatility,
as well as experience in each market, are all taken into account.
 The estimated credit risk associated with these instruments relates to the
failure of the counterparty to pay based on the contractual terms of the
agreement, and is generally limited to the gross unrealized market value gains
on these instruments. The amount of credit risk will increase or decrease
during the lives of the instruments as interest and foreign exchange rates
fluctuate. This risk is controlled by limiting such activity to an approved
list of counterparties and by subjecting such activity to the same credit and
quality controls as are followed in lending and investment activities.
 Risk management instruments include:
 FOREIGN EXCHANGE CONTRACTS are agreements to exchange specific amounts of
currencies at a future date, at a specified rate of exchange. Foreign exchange
contracts are entered into primarily to meet the foreign exchange risk
management needs of clients. Foreign exchange contracts are also used for
trading purposes and asset/ liability management.
 FOREIGN CURRENCY AND INTEREST RATE FUTURES CONTRACTS are agreements for
delayed delivery of foreign currency, securities or money market instruments in
which the buyer agrees to take delivery at a specified future date of a
specified currency, security, or instrument, at a specified price or yield. All
of Northern Trust's futures contracts are traded on organized exchanges that
require the daily settlement of changes in the value of the contracts. Futures
contracts are utilized in trading activities and asset/liability management to
protect Northern Trust's exposure to unfavorable fluctuations in foreign
exchange rates or interest rates.
 INTEREST RATE PROTECTION CONTRACTS are agreements which enable clients to
transfer, modify or reduce their interest rate risk. As a seller of interest
rate protection, Northern Trust receives a fee at the outset of the agreement
and then assumes the risk of an unfavorable change in interest rates. Northern
Trust also purchases interest rate protection contracts for asset/liability
management.
 INTEREST RATE SWAP CONTRACTS involve the exchange of fixed and floating rate
interest payment obligations without the exchange of the underlying principal
amounts; these types of transactions constitute the majority of the interest
rate swap portfolio. Northern Trust has also entered into a limited number of
more complex interest rate swap transactions that were executed concurrently
with the purchase of $298 million of structured agency notes. The structured
notes are included in the available for sale portion of the security portfolio.
The interest rate swap contracts are used to hedge the nonstandard features of
the structured notes thereby converting them to U.S. dollar denominated
floating rate notes indexed to LIBOR.
 FORWARD SALE CONTRACTS represent commitments to sell a specified amount of
securities at an agreed upon date and price. Northern Trust utilizes forward
sale contracts principally in connection with its sale of mortgage loans.
 EXCHANGE-TRADED OPTION CONTRACTS grant the buyer the right, but not the
obligation, to purchase or sell at a specified price, a stated number of units
of an underlying financial instrument, at a future date.
 The following table shows the contractual/notional amounts of risk management
instruments. The notional amounts of risk management instruments do not
represent credit risk, and are not recorded in the consolidated balance sheet.
They are used merely to express the volume of this activity.

RISK MANAGEMENT INSTRUMENTS USED FOR ASSET/LIABILITY MANAGEMENT. Northern Trust
utilizes various types of risk management instruments, primarily interest rate
swaps, as tools for managing interest rate and option risk related to its own
balance sheet. The following table summarizes the expected maturities and
weighted average interest rates to be paid and received on the asset/liability
management swap portfolio at December 31, 1996. A key assumption in the
preparation of the table is that floating rates remain constant at December 31,
1996 levels.

</TABLE>
 
 Some of the principal uses of risk management instruments, together with the
notional amounts outstanding, are described as follows:
 CONVERT YIELDS ON SECURITIES TO AN EFFECTIVE LIBOR RATE. At December 31, 1996,
interest rate swaps with a notional amount of $915 million and purchased
interest rate protection contracts with a notional amount of $25 million were
used to convert fixed and floating rate interest payments on securities
(classified as available for sale) to floating rate payments indexed to London
Interbank Offered Rates (LIBOR). Swaps with a notional amount of $532 million
were combined with fixed rate securities, $85 million were combined with
floating rate securities indexed to Treasury Bill rates, and $298 million were
combined with structured notes, whose non-standard features were hedged. The
swaps were executed simultaneously with the purchase of the notes. The
securities were converted to an effective LIBOR rate to match LIBOR-based
funding costs.
 REDUCE INTEREST RATE RISK FROM FIXED RATE LOANS FUNDED WITH VARIABLE RATE
LIABILITIES. Northern Trust paid a fixed rate and received a floating rate on
interest rate swaps with a notional amount of $1.2 billion at December 31, 1996
to hedge the interest rate risk from fixed rate loans. For accounting purposes
these swaps were designated to either convert the fixed rate on the loan to an
effective floating rate or to convert floating rate funding to a fixed rate.
 SWAPS AND FUTURES CONTRACTS COMBINED WITH LIABILITIES TO OBTAIN FAVORABLE
FUNDING COSTS. Interest rate swaps with a notional amount of $500 million at
December 31, 1996 were used in conjunction with the issuance of senior notes
and subordinated notes to obtain desired funding characteristics. Of these
swaps, $225 million converted fixed rate notes to floating rate funding indexed
to LIBOR, $75 million converted structured notes to a floating rate indexed to
LIBOR, and $200 million converted a fixed rate note to a floating rate over
part of its life. The use of swaps in combination with notes permitted Northern
Trust to issue notes with rate and maturity features that were most desired by
investors while converting the rate characteristics to meet its needs. Interest
rate futures contracts with a notional amount of $100 million were used to
hedge the anticipated issuance of federal funds purchased.
 HEDGING FOREIGN CURRENCY RISK. Forward foreign exchange contracts and foreign
currency futures contracts were used to reduce exposure to fluctuations in the
dollar value of capital investments in foreign subsidiaries and from foreign
currency obligations. The notional amounts of these contracts at year-end 1996
were $46.0 million of forward foreign exchange contracts and $3.3 million of
short sales of foreign currency futures contracts.
 HEDGING MORTGAGES HELD FOR SALE. Northern Trust hedges the market risk of its
portfolio of fixed rate commitments and mortgages held for sale with a
combination of derivative financial instruments. At December 31, 1996 the
portfolio was hedged with $11.3 million of forward sales of mortgage-backed
securities, $1.7 million of short sales of Treasury Note futures, and $2.8
million of purchases of put options on Treasury Note futures.

 No deferred gains or losses related to interest risk management instruments
used for asset/liability management were included in the consolidated balance
sheet at year-end 1996 or 1995.
 
CLIENT AND TRADING-RELATED INTEREST RISK MANAGEMENT INSTRUMENTS. Net revenue
associated with client and trading-related interest risk management activities
totaled $.3 million, $2.8 million, and $2.4 million during 1996, 1995, and
1994, respectively. The majority of these revenues are related to interest rate
swaps, futures contracts, and interest rate protection agreements, and are
reported as trading income in the consolidated statement of income. However,
the amounts reported for 1995 and 1994 also include interest income earned on
U.S. Government securities that were classified as trading account securities
and hedged with futures contracts.
 
 C. OTHER OFF-BALANCE SHEET FINANCIAL INSTRUMENTS. As part of securities custody
activities and at the direction of trust clients, Northern Trust lends
securities owned by clients to borrowers who are reviewed by the Credit Policy
Credit Approval Committee. In connection with these activities, Northern Trust
has issued certain indemnifications against loss resulting from the bankruptcy
of the borrower of securities. The borrowing party is required to fully
collateralize securities received with cash, U.S. Government and government
agency securities, or irrevocable standby letters of credit. As securities are
loaned, collateral is maintained at a minimum of 100 percent of the fair value
of the securities plus accrued interest, with revaluation of the collateral on a
daily basis. The amount of securities loaned as of December 31, 1996 and 1995
subject to indemnification was $15.7 billion and $8.2 billion, respectively.
Because of the requirement to fully collateralize securities borrowed,
management believes that the exposure to credit loss from this activity is
remote.
 The Bank is a participating member of various cash and securities clearing
organizations. It participates in these organizations on behalf of its clients
and on behalf of itself as a result of its own investment and trading
activities. A wide variety of securities transactions are settled through these
organizations, including those involving obligations of states and political
subdivisions, asset-backed securities, commercial paper, Eurodollars and
securities issued by the Government National Mortgage Association.
 As a result of its participation in cash and securities clearing
organizations, the Bank could be responsible for a pro rata share of certain
credit-related losses arising out of the clearing activities. The method in
which such losses would be shared by the clearing members is stipulated in each
clearing organization's membership agreement. Credit exposure related to these
agreements varies from day to day, primarily as a result of fluctuations in the
volume of transactions cleared through the organizations. The estimated credit
exposure at December 31, 1996 and 1995 was $70 million and $71 million,
respectively, based on the clearing volume for those days. Controls related to
these clearing transactions are closely monitored to protect the assets of
Northern Trust.
 
21. CONCENTRATIONS OF CREDIT RISK--The information in the section titled Loans
and Other Extensions of Credit found on pages 28 through 29 is incorporated by
reference.
 
22. PLEDGED AND RESTRICTED ASSETS--Certain of Northern Trust's subsidiaries, as
required or permitted by law, pledge assets to secure public and trust
deposits, repurchase agreements and for other purposes. On December 31, 1996,
securities and loans totaling $5.5 billion ($2.8 billion of U.S. Government and
agency securities, $393 million of obligations of states and political
subdivisions and $2.3 billion of loans and other securities), were pledged.
Collateral required for these purposes totaled $4.6 billion. Deposits
maintained at the Federal Reserve Bank to meet reserve requirements averaged
$247.8 million in 1996 and $278.1 million in 1995.
 
23. STOCK-BASED COMPENSATION PLANS--During 1995, the Financial Accounting
Standards Board issued SFAS No. 123, ""Accounting for Stock-Based
Compensation,'' which establishes financial accounting and reporting standards
for stock-based compensation plans.
 SFAS No. 123 allows two alternative accounting methods: (1) a fair-value-based
method, or (2) an intrinsic-value-based method which is prescribed by
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" (APB 25) and related interpretations. Both the accounting and
disclosure requirements of SFAS No. 123 were effective in 1996. Northern Trust
has elected to continue accounting for its stock-based incentive plans and
awards under its current method (APB 25), and has adopted the disclosure
requirements of SFAS No. 123.
 A description of Northern Trust's stock-based compensation accounted for under
APB 25 is presented below.
 
AMENDED INCENTIVE STOCK PLAN--AMENDED 1992 INCENTIVE STOCK PLAN (PLANS). The
Amended Incentive Stock Plan was superseded by the Amended 1992 Incentive Stock
Plan and terminated on December 31, 1994. Outstanding grants and awards under
the Amended Incentive Stock Plan will remain in effect in accordance with their
terms, but no further grants or awards will be made.
 The Amended 1992 Incentive Stock Plan (Plan) was adopted in 1992 and amended
in 1995. The Plan is administered by the Compensation and Benefits Committee
(Committee) of the Board of Directors. Key officers of the Corporation or its
subsidiaries are eligible to receive awards under the Plan. Awards under the
Plan may be granted in

any one or a combination of (a) incentive stock options and non-qualified stock
options, (b) stock appreciation rights, (c) stock awards, (d) performance
shares, and (e) stock equivalents.
 The total number of shares of the Corporation's common stock authorized for
distribution under the Plan is 7,500,000. As of December 31, 1996, shares
available for future grants under the Plan totaled 130,358.
 STOCK OPTIONS. Stock options consist of options to purchase common stock at
purchase prices not less than 100% of the fair market value thereof on the date
the option is granted. Options have a 10 year life and will vest and become
exercisable in 2 years after the date of grant. In addition, the Plan provides
that all options will become exercisable upon a change of control as defined in
the Plan. All options terminate at such time as determined by the Committee and
as provided in the terms and conditions of the respective option grants.
 A summary of the status of stock options under the Plans at December 31, 1996
and 1995 and changes during the years then ended is presented in the table and

$26.78 and $33.50, with a weighted average exercise price of $33.16 and a
weighted average contractual life of 9.7 years, none of which are exercisable.
 STOCK AWARDS. Under the Plans, stock awards or equivalents can be awarded by
the Committee to participants which entitle them to receive a payment in cash
or Northern Trust Corporation common stock based on such terms and conditions
as the Committee deems appropriate.
 Total expense applicable to stock awards was $.5 million in 1996 and $.4
million in both 1995 and 1994. In 1996, 12,000 shares of restricted stock were
awarded with a weighted average grant-date fair value of $26.78. No shares were
awarded in 1995. As of December 31, 1996 restricted stock awards outstanding
totaled 117,000 shares. These shares vest, subject to continuing employment,
over a period of five to nine years.
 PERFORMANCE SHARES. Under the performance share provisions of the Plans,
participants will be entitled to have each award credited to an account
maintained for them if established performance goals are achieved with
distribution after vesting. The value of shares earned but not yet distributed
under the plan is credited to performance share accounts and is shown in
stockholders' equity as common stock issuable-performance plan.
 Total salary expense for performance shares was $9.7 million in 1996, $5.6
million in 1995 and $5.2 million in 1994. In 1996 and 1995, 331,000 and 306,500
shares respectively, were granted with a weighted average grant-date fair value
of $26.88 and $17.00, respectively. As of December 31, 1996, 505,000 shares of
stock had been credited to performance share accounts subject to meeting
vesting conditions and 1,119,548 shares had been granted, subject to meeting
established performance goals and vesting conditions, for three-year
performance periods ending in 1996 through 1998.
 
OTHER STOCK-BASED COMPENSATION ARRANGEMENTS. The Corporation, in conjunction
with an acquisition, awarded 432,280 restricted shares of the Corporation's
common stock with a grant-date fair value of $23.75 to certain subsidiary
employee participants contingent upon continued employment, non-competition
agreements and, in some cases, meeting predetermined performance goals.
 Total salary expense related to this arrangement totaled $1.8 million in 1996
and $.3 million in 1995.
 
PRO FORMA INFORMATION. Pro forma information regarding net income and earnings
per share is required by SFAS No. 123, and has been determined as if the
Corporation had accounted for its stock-based compensation under SFAS No. 123.
For purposes of estimating the fair value of the Corporation's employee stock
options at the grant-date, a Black-Scholes option pricing model was used with
the following weighted average assumptions for 1996 and 1995, respectively:
risk-free interest rates of 6.64% and 6.54%; dividend yields of 1.92% and
2.21%; volatility factors of the expected market price of the Corporation's
common

Northern Trust Corporation
<PAGE>
 
stock of 22.4% and 19.2%; and a weighted average expected life of the option of
5.8 years. The weighted average fair value of options granted in 1996 and 1995
was $9.11 and $6.58, respectively. For purposes of pro forma disclosures, the
estimated fair value of the options is amortized to expense over the options'
two year vesting period. Under SFAS No. 123, options and awards granted prior
to 1995 are not required to be included in the pro forma information. Because
the SFAS No. 123 method of accounting has not been applied to options and other
stock-based compensation granted prior to January 1, 1995, the resulting pro
forma compensation cost may not be representative of that to be expected in
future years. The Corporation's pro forma information follows:

24. CASH-BASED COMPENSATION PLANS--Various incentive plans provide for cash
incentives and bonuses to selected employees based upon accomplishment of
corporate net income objectives, business unit goals and individual
performance. The plans provide for acceleration of benefits in certain
circumstances including a change in control. The estimated contributions to
these plans are charged to salary expense and totaled $45.3 million in 1996,
$35.7 million in 1995 and $28.4 million in 1994.

25. INTERNATIONAL OPERATIONS (BASED ON OBLIGOR'S DOMICILE)--Northern Trust's
international activities are centered in the commercial banking, capital
markets and global custody businesses of the Bank, three overseas branches, one
Edge Act subsidiary, the Hong Kong subsidiaries, NTGA, and Northern Trust of
Florida. Total assets employed in international operations were $2.8 billion on
December 31, 1996, $2.3 billion on December 31, 1995 and $2.8 billion on
December 31, 1994. Of these assets, $1.3 billion on December 31, 1996, $1.1
billion on December 31, 1995 and $1.5 billion on December 31, 1994 were
employed in Europe.
 Net income from international operations includes the direct net income
contributions of foreign branches, foreign subsidiaries and the Edge Act
subsidiary. The Bank and Northern Trust of Florida international profit
contributions reflect direct salary and other expenses of the business units,
plus expense allocations for interest, occupancy, overhead and the provision for
credit losses. The interest expense is allocated to international operations
based on specifically matched or pooled funding. Allocations of indirect
noninterest expenses related to international activities are not significant
but, when made, are based on various methods such as time, space and number of
employees.

26. ACQUISITIONS--On March 31, 1995, the Corporation completed the acquisition
of Beach One Financial Services, Inc., parent company of The Beach Bank of Vero
Beach, Florida. The acquisition was effected through a merger in which the
Corporation issued 3,245,136 shares (adjusted for two-for-one stock split
payable to stockholders of record at December 2, 1996) of its common stock
totaling $56.2 million. The Corporation has accounted for the transaction as
pooling-of-interests. Prior period consolidated financial statements were not
restated due to the immateriality of the transaction.
 On July 31, 1995, the Corporation completed the acquisition of Tanglewood
Bancshares, Inc., parent company of Tanglewood Bank N.A. of Houston, Texas for
$32.5 million in cash. The transaction was recorded under the purchase method
of accounting. Included in the acquisition cost were $14.4 million of goodwill
and $5.8 million of other intangibles, which are being amortized over fifteen
and ten years, respectively.
 On October 31, 1995, the Corporation completed the acquisition of RCB
International Inc. (RCB), an international provider of institutional investment
 
60
Northern Trust Corporation
<PAGE>
 
management services. RCB shareholders received at closing $11.0 million in
cash, $.6 million in notes and 784,862 shares (adjusted for two-for-one split)
of Corporation common stock. The transaction was recorded under the purchase
method of accounting. In addition, 432,280 shares (adjusted for two-for-one
stock split) of Corporation common stock and $2.6 million in cash were
allocated for various deferred compensation plans and other deferred payment
arrangements. Shares and cash available under these deferred payment
arrangements are payable over one to seven years and are contingent upon
continued employment, non-competition agreements and, in some cases, meeting
predetermined performance goals. Included in the acquisition cost of RCB were
$18.8 million of goodwill and $8.0 million of other intangibles, both of which
are being amortized over a fifteen year period. In August 1996, RCB's name was
changed to Northern Trust Global Advisors, Inc.
 On November 15, 1996, the Corporation completed the acquisition of Metroplex
Bancshares, Inc., parent company of Bent Tree National Bank (Bent Tree) in
Dallas, Texas for $14.6 million in cash. The transaction was recorded under the
purchase method of accounting. Included in the acquisition cost were $6.0
million of goodwill and $2.1 million of other intangibles, which are being
amortized over fifteen and ten years, respectively. Bent Tree is expected to be
merged into Northern Trust Bank of Texas N.A. during the first quarter of 1997.
 
27. REGULATORY CAPITAL REQUIREMENTS--Northern Trust and its subsidiary banks
are subject to various regulatory capital requirements administered by the
federal bank regulatory authorities. Under these requirements, banks must
maintain specific ratios of total and tier I capital to risk-weighted assets and
of tier I capital to average assets in order to be classified as ""well
capitalized.'' The regulatory capital requirements impose certain restrictions
upon banks that meet minimum capital requirements but are not ""well
capitalized'' and obligate the federal bank regulatory authorities to take
""prompt corrective action'' with respect to banks that do not maintain such
minimum ratios. Such prompt corrective action could have a direct material
effect on a bank's financial statements.
 As of December 31, 1996, each of Northern's significant subsidiary banks had
capital ratios above the level required for classification as a "well
capitalized" institution and had not received any regulatory notification of a
lower classification. There are no conditions or events since that date, that
management believes have adversely affected the capital categorization of any
significant subsidiary bank for these purposes. The following table summarizes
the risk-

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
- --------------------------------------------------------------------------------

TO THE STOCKHOLDERS AND BOARD OF DIRECTORS,
NORTHERN TRUST CORPORATION:
 
We have audited the accompanying consolidated balance sheet of Northern Trust
Corporation (a Delaware Corporation) and subsidiaries as of December 31, 1996
and 1995, and the related consolidated statements of income, changes in
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1996. These financial statements are the responsibility of
the Corporation's management. Our responsibility is to express an opinion on
these financial statements based on our audits.
 We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Northern Trust Corporation and
subsidiaries as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996 in conformity with generally accepted accounting principles.
 
                                                             Arthur Andersen LLP

     1994, $34.1 million in 1993 and $32.5 million in 1992.
