                          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
fiduciary services to clients residing outside of the United States. Northern

in Atlanta, Georgia, and was formerly known as Hazlehurst & Associates, Inc.
Northern Trust Global Advisors, Inc. in Stamford, Connecticut (formerly known as
RCB International Inc.) is an international provider of institutional

                             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.
- --------------------------------------------------------------------------------
                                       5

- --------------------------------------------------------------------------------
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,

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
- --------------------------------------------------------------------------------
                                       8

- --------------------------------------------------------------------------------
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.

     The Securities and Exchange Commission requires the disclosure of the 
reserve for credit losses that is applicable to international operations. The
above table has been prepared in compliance with this disclosure requirement and
is used in determining international operating performance. The amounts shown in
the table should not be construed as being the only amounts that are available
for international loan charge-offs, since the entire reserve for credit losses
is available to absorb losses on both domestic and international loans. In
addition, these amounts are not intended to be indicative of future charge-off
trends.

                            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.

     As required by the Securities and Exchange Commission, the following tables
break down the reserve for credit losses:

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

     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.
