Item 1-Business 

                          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 on December 1 of 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. The Corporation also owns two
banks in Florida, one bank in each of Arizona, California and Texas, Connecticut
and New York trust companies 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, 1995, Northern Trust had consolidated total assets of
approximately $19.9 billion and stockholders' equity of $1.5 billion. At June
30, 1995 Northern Trust was the third largest bank holding company headquartered
in Illinois and the 38th largest in the United States, based on consolidated
total assets of approximately $19.3 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 one hundred and seventh year, the
Bank's growth has come primarily from internal sources rather than through
merger or acquisition. At December 31, 1995, the Bank had consolidated assets of
approximately $15.2 billion. At June 30, 1995, the Bank was the third largest
bank in Illinois and the 41st largest in the United States, based on
consolidated total assets of approximately $15.1 billion on that date.

     The Bank currently has eight 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
and Northern Trust Trade Services, Limited. 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.

                 OTHER NORTHERN TRUST CORPORATION SUBSIDIARIES

     On February 29, 1996, three Illinois banking subsidiaries of the
Corporation merged into the Bank: Northern Trust Bank/O'Hare N.A., Northern
Trust Bank/DuPage, and Northern Trust Bank/Lake Forest N.A. As a result, the
Bank now operates fourteen offices in the Chicago metropolitan area. The
Corporation's Florida banking subsidiaries, Northern Trust Bank of Florida N.A.,
headquartered in Miami, and the Northern Trust Bank of Vero Beach, at December
31, 1995, had twenty-two offices located throughout Florida, with total assets
of approximately $1.8 billion. The Corporation's Arizona banking subsidiary,
Northern Trust Bank of Arizona N.A., is headquartered in Phoenix and at December
31, 1995 had total assets of approximately $315 million and served clients from
five office locations. The Corporation has a Texas banking subsidiary, Northern
Trust Bank of Texas N.A., headquartered in Dallas. It had six office locations
and total assets of approximately $456 million at December 31, 1995. The
Corporation's California banking subsidiary, Northern Trust Bank of California
N.A., is headquartered in Santa Barbara. At December 31, 1995, it had six office
locations and total assets of approximately $288 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
an investment management firm in San Francisco, California. The Northern Trust
Company of New York provides security clearance services for all nondepository
eligible

                                       4
<PAGE>
 
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. Hazlehurst 
& Associates, Inc. is a retirement benefit plan services company in Atlanta, 
Georgia. RCB International, Inc. in Stamford, Connecticut is an international 
provider of institutional investment management services, and the parent of 
RCB Trust Company.

                             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, along
with Investment Services, Corporate Compliance and Corporate Support Services,
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 (C&IS)

     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 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 markets 
foreign to the client is provided primarily through the Bank's London Branch. 
Related foreign exchange services are also rendered at the London Branch as 
well as in Chicago.

     As measured by number of clients, Northern Trust is a leading provider of
Master Trust and Master Custody services in various market segments. At December
31, 1995, total assets under administration were $550.5 billion. The major
market segments served are large U.S. corporate, middle market, 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, Hazlehurst & Associates, Inc., and RCB International, 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 Corporations Group and a Financial Institutions Group.

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

Personal Financial Services (PFS)

     Services to individuals is another major dimension of the trust business.
Headed by Mark Stevens, Executive Vice President of the Corporation and the
Bank, Personal Financial Services (PFS) encompasses personal trust, estate
administration, personal banking, mortgage lending and trust and banking
services to 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 Florida, Arizona, California and Texas. PFS is one of
the largest bank managers of personal trust assets in the United States, with
total assets under administration of $63.4 billion at December 31, 1995.

     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 the Bank, this unit focuses on supporting
sales, relationship management, transaction processing and product management
activities for C&IS and PFS.

                                       5

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 the 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. Its
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
the Federal Reserve Board's regulations, a bank holding company, as well as
certain of its subsidiaries, are prohibited from engaging in certain tie-in
arrangements in connection with any extension of credit or provision of any
property or services.

                                       6
<PAGE>
 
     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. Beginning September 29, 1995 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. Effective as of September 29, 1994, the
Interstate Act 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. The Interstate Act permits as
of September 29, 1995 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.

     The Financial Institutions Reform, Recovery and Enforcement Act of 1989
(FIRREA) amended the Act to authorize the Federal Reserve Board to allow bank
holding companies to acquire any savings association (whether healthy, failed or
failing) and removed "tandem operations" restrictions, which previously
prohibited savings associations from being operated in tandem with a bank
holding company's other subsidiaries. As a result, bank holding companies now
have expanded opportunities to acquire savings associations.

     Under FIRREA, 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 FIRREA, 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 the provisions of FIRREA.

     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 Commissioner of Banks and Trust Companies. 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. is registered with the Securities
and Exchange Commission under the Investment Advisers Act of 1940 and is subject
to that Act and the rules and regulations of the Commission promulgated
thereunder. RCB International, Inc. is subject to regulation by the Securities
and Exchange Commission and the Illinois Securities Department. Its subsidiary
RCB Trust Company is subject to

                                       7
<PAGE>
 
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. 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 dividend restrictions on banking subsidiaries is
incorporated herein by reference to Note 12 titled Restrictions on Subsidiary
Dividends and Loans or Advances on page 46 of the Corporation's Annual Report to
Stockholders for the year ended December 31, 1995.

     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 1996 to no assessment, and banks classified as weakest by the FDIC
are subject to an assessment rate of .27%.

     The Federal Deposit Insurance Corporation Improvement Act of 1991 (FDICIA)
substantially revised the bank regulatory and funding provisions of the Federal
Deposit Insurance Act and made revisions to several other federal banking
statutes. In general, FDICIA subjects banks to significantly increased
regulation and supervision. Among other things, FDICIA requires federal bank
regulatory authorities to take "prompt corrective action" with respect to banks
that do not meet minimum capital requirements, and imposes certain restrictions
upon banks which meet minimum capital requirements but are not "well
capitalized" for purposes of FDICIA. FDICIA and the regulations adopted under it
establish five capital categories as follows, with the category for any
institution determined by the lowest of any of these ratios:

     *3% for banks with the highest CAMEL (supervisory) rating.

     An insured depository institution may be deemed to be in a capital category
that is lower than is indicated by the capital position reflected on its balance
sheet if it receives an unsatisfactory rating by its examiners with respect to
its assets, management, earnings or liquidity. Although a bank's capital
categorization thus depends upon factors in addition to the balance sheet ratios
in the table above, the Corporation has set goals for each of its subsidiary
banks that would allow each bank to meet the minimum ratios that are one of the
conditions for it to be considered to be well capitalized. At December 31, 1995,
the Bank and each of the other subsidiary banks met or exceeded these goals. The
capital ratios are disclosed and discussed on page 30 of the Corporation's
Annual Report to Stockholders for the year ended December 31, 1995.

     Under FDICIA, a bank that is not well capitalized is generally prohibited
from accepting or renewing brokered deposits and offering interest rates on
deposits significantly higher than the prevailing rate in its normal market area
or nationally (depending upon where the deposits are solicited); in addition,
"pass through" insurance coverage may not be available for certain employee
benefit accounts.

     FDICIA generally prohibits a depository institution from making any capital
distribution (including payment of a dividend) or paying any management fee to
its holding company if the depository institution would thereafter be
undercapitalized. Undercapitalized banks are subject to limitations on growth
and are required to submit a capital restoration plan, which must be guaranteed
by the institution's parent company. Institutions that fail to submit an
acceptable plan, or that are significantly undercapitalized, are subject to a
host of more drastic regulatory restrictions and measures.

     FDICIA directs that each federal banking agency prescribe standards for
depository institutions or depository institutions' holding companies relating
to internal controls, information systems, internal audit systems, loan
documentation, credit underwriting, interest rate exposure, asset growth,
compensation, a maximum ratio of classified assets to capital, minimum earnings
sufficient to absorb losses and other standards as they deem appropriate. Many
regulations implementing these directives have been adopted by the agencies.


                                       8

     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.

STAFF

     The Securities and Exchange Commission requires the disclosure of 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 Credit Policy Credit Approval 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, leases and credit related exposures. 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.

     In prior years, 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.
This allocation method should not be interpreted as an indication of expected
losses within the next year or any specified time period.

                                  ARTICLE IV
                    INVESTMENT OF SUPPLEMENTAL ALLOCATIONS

4.1  Investments. The Company may contribute amounts allocated hereunder to the
Supplemental ESOP Accounts of Participants to a trust ("Trust") established
under the trust agreement between the Company and Harris Trust & Savings Bank, a
bank organized and existing under the laws of the State of Illinois, as trustee
("Trust Agreement"). Amounts allocated hereunder to the Supplemental ESOP
Account of a Participant and contributed to the Trust, shall be invested in one
or more of the investment funds from time to time offered by the trustee of the
Trust Agreement as set forth on Schedule A attached hereto and shall be subject
to the same administrative procedures and Participant investment elections that
apply to his Supplemental Matching Contribution Account.

A Participant shall be entitled to change investment elections applicable to his
Supplemental ESOP Account, or to direct transfers of amounts in his Supplemental
ESOP Account among the investment funds set forth on Schedule A, provided that
such directions shall also apply to his Supplemental Matching Contribution
Account. Such changes can be made monthly by written request.

4.2  Company Securities.  Notwithstanding anything to the contrary contained
herein, in no event shall amounts allocated to the Supplemental ESOP Account of
a Participant be invested in any fund that provides for investment in stock or
other securities of the Company; provided, however, that nothing contained
herein shall prohibit
<PAGE>
 
investment of amounts allocated to the Supplemental ESOP of any Participant in a
common or collective trust fund of the trustee of the Trust Agreement in which
no more than five percent of the total fair market value of the assets of such
common or collective trust fund are invested in stock or other securities of the
Company.


                                  ARTICLE V
                                DISTRIBUTIONS

5.1  Distribution. (a) In the event that the Participant's employment with the
Company terminates for any reason, the Participant shall receive on the last day
of the calendar month following the month in which such termination occurs, a
lump sum distribution, in cash, equal to the vested adjusted balance of the
Participant's Supplemental ESOP Account, including gains or losses attributable
to investments made pursuant to Section 4.1, determined as of the last day of
the calendar month in which such termination occurs. Notwithstanding the
foregoing, if a Participant is entitled to receive a Supplemental ESOP
Allocation for the Plan Year in which he terminated employment, such
Supplemental ESOP Allocation and any gains or losses attributable thereto shall
be distributed to or with respect to the Participant upon completion of the
first valuation following the posting of such Supplemental ESOP Allocation to
his Supplemental ESOP Account.

Any nonvested portion of a Participant's Supplemental ESOP Account shall be
forfeited and retained by the Company.

(b)  The amount to be paid from the Supplemental ESOP in the year of the
Participant's termination shall be limited to an amount which will not cause the
total amount of compensation received from the Company, to exceed the maximum
amount deductible by the Company under Code section 162(m). Amounts not paid as
a result of the above limitation shall be paid in subsequent years, to the
extent permissible under the above limitation.

(c)  If a Participant dies before a complete distribution of his Supplemental
ESOP Account has been made to him, the vested adjusted balance of such
Participant's Supplemental ESOP Account, including gains or losses attributable
to investments made pursuant to Section 4.1, determined as of the last day of
the calendar month in which the Participant's employment with the Company
terminated, shall be distributed in one lump sum, in cash, to the Beneficiary
last designated by the Participant in a writing delivered to the Committee prior
to his death. If a Participant has not designated a Beneficiary, or if no
designated Beneficiary is living on the date of distribution, the vested
adjusted balance of such Participant's Supplemental ESOP Account, shall be
distributed in one lump sum, in cash, to those persons entitled to receive
distributions of the Participant's accounts under the Qualified Plan.


                                  ARTICLE VI
                          ADMINISTRATION OF THE PLAN
<PAGE>
 
6.1  Administration by the Committee. The Committee shall be responsible for the
general operation and administration of the Plan and for carrying out the
provisions thereof. The Committee shall have discretion to interpret and
construe the provisions of the Plan.

6.2  General Powers of Administration. All provisions set forth in the Qualified
Plan with respect to the administrative powers and duties of the Committee,
expenses of administration, and procedures for filing claims shall also be
applicable with respect to the Plan. The Committee shall be entitled to rely
conclusively upon all tables, valuations, certificates, opinions and reports
furnished by any actuary, accountant, controller, counsel or other person
employed or engaged by the Committee with respect to the Plan.


                                  ARTICLE VII
                            AMENDMENT OR TERMINATION

7.1  Amendment or Termination. The Company intends the Plan to be permanent but
reserves the right to amend or terminate the Plan when, in the sole discretion
of the Company, such amendment or termination is advisable. Any such amendment
or termination shall be made pursuant to a resolution of the Board and shall be
effective as of the date set forth in such resolution.

7.2  Effect of Amendment or Termination. No amendment or termination of the Plan
shall directly or indirectly reduce the balance of any Supplemental ESOP Account
held hereunder as of the effective date of such amendment or termination. Upon
termination of the Plan, disribution of amounts in a Participant's Supplemental
ESOP Account shall be made to him or his Beneficiary in the manner and at the
time described in Section 5.1 of the Plan. No additional Supplemental ESOP
Allocations shall be made to the Supplemental ESOP Account of any Participant
after termination of the Plan.


                                  ARTICLE VIII
                               GENERAL PROVISIONS


8.1  Participant's Rights Unsecured. The Plan at all times shall be entirely
unfunded and no provision shall at any time be made with respect to segregating
any assets of the Company for payment of any benefits hereunder. No Participant,
beneficiary or any other person shall have any interest in any particular assets
of the Company by reason of the right to receive a benefit under the Plan and
any such Participant, Beneficiary or other person shall have only the rights of
a general unsecured creditor of the Company with respect to any rights under the
Plan.

8.2  General Conditions.  Except as otherwise expressly provided herein, all
terms and conditions of the Qualified Plan applicable to allocations of Company
Stock under the Qualified Plan shall also be applicable to a Supplemental ESOP
Allocation made hereunder. Any allocation of Company Stock or dividends to be
made under the Qualified
<PAGE>
 
Plan shall be made solely in accordance with the terms and conditions of the
Qualified Plan and nothing in this Plan shall operate or be construed in any way
to modify, amend or affect the terms and provisions of the Qualified Plan.

8.3  No Guaranty of Benefits. Nothing contained in the Plan shall constitute a
guaranty by the Company or any other person or entity that the assets of the
Company will be sufficient to pay any benefit hereunder.

8.4  No Enlargement of Employee Rights. No Participant shall have any right to
receive a distribution under the Plan except in accordance with the terms of the
Plan. Establishment of the Plan shall not be construed to give any Participant
the right to be retained in the service of the Company.

8.5  Spendthrift Provision. No interest of any person or entity in, or right to
receive a distribution under, the Plan shall be subject in any manner to sale,
transfer, assignment, pledge, attachment, garnishment, or other alienation or
encumbrance of any kind; nor may such interest or right to receive a
distribution be taken, either voluntarily or involuntarily, for the satisfaction
of the debts of, or other obligations or claims against, such person or entity,
including claims for alimony, support, separate maintenance and claims in
bankruptcy proceedings.

8.6  Applicable Law. The Plan shall be construed and administered under the laws
of the State of Illinois to the extent not inconsistent with the Employee
Retirement Income Security Act of 1974.

8.7  Incapacity of Recipient. If any benefit under the Plan shall be payable to
a minor or a person not adjudicated incompetent but who, by reason of illness or
mental or physical disability, is, in the opinion of the Committee, unable to
properly manage his affairs, such benefit shall be paid in such of the following
ways as the Committee deems best: (a) to the person directly; (b) in the case of
a minor, to a custodian under any Uniform Gift to Minors Act for the person; or
(c) to the person's spouse, adult child or blood relative. Any benefit so paid
shall be a complete discharge of any liability of the Company and Plan therefor.

8.8  Successors. The Plan shall not be automatically terminated by a transfer or
sale of assets of the Company or by the merger or consolidation of the Company
into or with any other corporation or other entity, but the Plan shall be
continued after such sale, merger or consolidation only if and to the extent
that the transferee, purchaser or successor entity agrees to continue the Plan.
In the event that the Plan is not continued by the transferee, purchaser or
successor entity, then the Plan shall terminate subject to the provisions of
Section 7.2.

8.9  Unclaimed Benefit. Each Participant shall keep the Committee informed of
his current address and the current address of his designated Beneficiary.
Neither the Company nor the Committee shall be obligated to search for the
whereabouts of any person. If the location
<PAGE>
 
of a Participant is not made known to the Committee within three (3) years after
the date on which distribution of the Participant's Supplemental ESOP Account
may first be made, distribution may be made as though the Participant had died
at the end of the three-year period. If, within one additional year after such
three-year period has elapsed, or within three years after the actual death of a
Participant, neither the Company nor the Committee is able to locate any
designated Beneficiary of the Participant, then the Company shall have no
further obligation to pay any benefit hereunder to such Participant or
designated Beneficiary and such benefit shall be irrevocably forfeited;
provided, however, that if the Participant or designated Beneficiary makes a
valid claim for any benefit that has been so forfeited, the forfeited benefit
shall be reinstated.

8.10  Limitations on Liability. Notwithstanding any of the preceding provisions
of the Plan, neither the Company, any member of the Committee, nor any
individual acting as an employee or agent of the Company or Committee shall be
liable to any Participant, former Participant, Beneficiary or any other person
for any claim, loss, liability or expense incurred in connection with the Plan.

feminine and the singular shall include the plural, and vice versa, unless

reference only, and are not to be construed so as to alter the terms hereof.

IN WITNESS WHEREOF, The Northern Trust Company has caused this Plan to be signed
by its duly authorized officer as of the 31st day of December, l995.

                                  ELIGIBILITY


2.1  (a) Conditions for Participation. An employee of the Company: (i) who is
eligible to participate in the Qualified Plan on the first day of a Plan Year
and (ii) whose Salary (as defined in the Qualified Plan), determined as of
November 30 of the prior plan year, exceeds the compensation limitation under
Section 40l(a)(17) of the Code for such prior Plan Year, shall be eligible to
make salary deferrals under the Plan for such Plan Year as soon as he has
reached the Code Section
<PAGE>
 
40l(a)(17) limitation. However, if the compensation limit for the Plan Year for
which participation is being determined is known by November 30 of such prior
Plan Year, participation will be based upon such limit.

In the event an employee of the Company who is ineligible to participate in the
Plan on the first day of a Plan Year either because he was not eligible for the
Qualified Plan on the first day of the Plan Year or because his Salary does not
exceed the Code Section 40l(a)(17) limitation for the prior Plan Year
subsequently becomes eligible for the Qualified Plan or has his Salary increased
and becomes ineligible to make contributions to the Qualified Plan because his
Salary exceeds the compensation limit set forth in Code Section 40l(a)(17), such
employee shall become eligible to participate in the Plan for purposes of
Supplemental Matching Contributions only as of the date he is no longer eligible
to make contributions to the Qualified Plan as a result of the above limitation.
Such Supplemental Matching Contributions shall be based on the employee's rate
of contribution to the Qualified Plan at the time his contributions ceased.

(b)  Participant Elections. An employee who meets the eligibility requirements
on November 30 for Plan participation in the following Plan Year will be allowed
to elect (i) to decline participation in the Plan, or (ii) to begin
contributions to the Plan once he is no longer able to contribute to the
Qualified Plan because he has reached the limitations of Section 40l(a)(17).


                                  ARTICLE III
                          SUPPLEMENTAL CONTRIBUTIONS

3.1  Supplemental Before-Tax Deposit.  The Supplemental Before-Tax Deposit
authorized by a Participant for any Plan Year shall be applied only to salary in
excess of Section 40l(a)(17) limitations, in any amount equal to at least one
percent (1%), but not to exceed twelve percent (12%).

The Supplemental Before-Tax Deposit made for the benefit of a Participant for
any Plan Year shall be allocated to a Supplemental Before-Tax Deposit Account
maintained under the Plan in the name of such Participant on or before the last
day of such Plan Year.

3.2  Supplemental Before-Tax Deposit Agreement. As a condition to the Company's
obligation to make a Supplemental Before-Tax Deposit for the benefit of a
Participant pursuant to Section 3.1 for any Plan Year, the Participant must
execute a Supplemental Before-Tax Deposit Agreement, in such form as the
Committee in its discretion shall determine, on which the Participant shall
elect to have his Salary for such Plan Year reduced, and a Supplemental Before-
Tax Deposit made on his behalf, on salary in excess of Section 40l(a)(17)
limitations, in any amount equal to at least one percent (l%) of his Salary, or
any multiple thereof, but not to exceed twelve percent (12%).

An Agreement that is effective for any Plan Year shall be executed and delivered
to the Committee by the specified date before the beginning
<PAGE>
 
of that Year and shall be irrevocable for that year and for subsequent Years
unless and until revoked or revised by a Participant by written instrument
delivered to the Committee prior to the beginning of the Plan Year in which such
revocation or revision is to be effective.

3.3  Supplemental Matching Contributions.  The Supplemental Matching 
Contribution to be made by the Company on behalf of a Participant for any Plan
Year who (i) is a Participant at the beginning of a Plan Year eligible to make
salary deferrals after reaching the Section 40l(a)(17) limitations, who actually
makes salary deferrals or (ii) during the Plan Year becomes a Participant
eligible to participate for purposes of Supplemental Matching Contributions
only, shall be made in accordance with the matching contribution formula and
provisions set forth in the Qualified Plan.

Supplemental Matching Contributions made for the benefit of a Participant for
any Plan Year shall be allocated to a Supplemental Matching Contribution Account
maintained under the Plan in the name of such Participant as of the last day of
such Plan Year.

3.4  Vesting of Benefits.  Each Participant shall at all times be fully vested 
in the adjusted balance of his Supplemental Before-Tax Deposit Account. Each
Participant shall vest in the adjusted balance of his Supplemental Matching
Contribution Account in accordance with the vesting schedule applicable to his
Qualified Plan Matching Contribution Account set forth in the Qualified Plan.
Notwithstanding the preceding sentence or any other provision of the Plan, each
Participant shall become fully vested in the adjusted balance of his
Supplemental Matching Contribution Account on the effective date of a Change-in-
Control.


                                  ARTICLE IV
                  INVESTMENT OF SUPPLEMENTAL CONTRIBUTIONS

4.1  Investments.  The Company may contribute amounts allocated hereunder to
the Supplemental Accounts of Participants to a trust ("Trust") established under
the trust agreement between the Company and Harris Trust & Savings Bank, a bank
organized and existing under the laws of the State of Illinois, as trustee
("Trust Agreement"). Amounts allocated hereunder to the Supplemental Account of
a Participant shall be subject to such administrative procedures relating to
investment elections as the Committee may from time to time establish. When
amounts are allocated to the Supplemental Account of a Participant and are
contributed to the Trust, they shall be invested in one or more of the
investment funds from time to time offered by the trustee of the Trust
Agreement, as set forth on Schedule A attached hereto.

A Participant shall be entitled to change investment elections applicable to his
Supplemental Account, or to direct transfers of amounts in his Supplemental
Account among the investment funds set forth on Schedule A, provided that such
directions shall also apply to his Supplemental ESOP Allocation. Such changes
can be made monthly by written request.
<PAGE>
 
4.2  Company Securities.  Notwithstanding anything to the contrary contained
herein, in no event shall amounts allocated to the Supplemental Account of a
Participant be invested in any fund that provides for investment in stock or
other securities of the Company; provided, however, that nothing contained
herein shall prohibit investment of amounts allocated to the Supplemental
Account of any Participant in a common or collective trust fund of the trustee
of the Trust Agreement in which no more than five percent of the total fair
market value of the assets of such common or collective trust fund are invested
in stock or other securities of the Company.


                                  ARTICLE V
                                DISTRIBUTIONS

5.1  Distribution.  (a)  Subject to Section 8.2, all amounts allocated to a
Participant's Supplemental Before-Tax Deposit Account, including gains and
losses attributable to investments made pursuant to Section 4.1, shall be
distributed to or with respect to the Participant in one lump sum as of the
first to occur of (a) the Deferral Distribution Date irrevocably set forth
in the related Supplemental Before-Tax Deposit Agreement or (b) the last day of
the calendar month following the month in which the Participant's employment
with the Company terminates for any reason, including death. The vested adjusted
balance of a Participant's Supplemental Matching Contribution Account, including
gains and losses attributable to investments made pursuant to Section 4.1, shall
be distributed to or with respect to a Participant as of the last day of the
calendar month following the month in which the Participant's employment with
the Company and all affiliates terminates for any reason, including death.
Notwithstanding the foregoing, if a Participant is entitled to receive a
Supplemental Matching Contribution for the Plan Year in which he terminated
employment, such Supplemental Matching Contribution and any gains or losses
attributable thereto shall be distributed to or with respect to the Participant
upon completion of the first valuation following the posting of such
Supplemental Matching Contribution to the Supplemental Matching Contribution
Account.

Any unvested amounts credited to a Participant's Supplemental Matching
Contribution Account shall be forfeited and retained by the Company.

(b)  The annual amount to be paid from the Supplemental TIP shall be limited
to an amount which will not cause the total amount of compensation received
from The Northern Trust to exceed the maximum amount deductible by The
Northern Trust under Code section 162(m).  Amounts not paid as a result of
the above limitation shall be paid in subsequent years, to the extent
permissible under the above limitation.

(c)  If a Participant dies before a complete distribution of his Supplemental 
Before Tax Deposit Account or his Supplemental Matching Contribution Account has
been made to him, such amounts shall be distributed to the Beneficiary
designated by the Participant in a writing last delivered to the Committee prior
to his death. If a Participant has not designated a Beneficiary, or if no
designated Beneficiary is living on the date of distribution, such amounts shall
<PAGE>
 
be distributed to those persons entitled to receive distributions of the
Participant's accounts under the Qualified Plan.


                                  ARTICLE VI
                          ADMINISTRATION OF THE PLAN

6.1  Administration by the Committee.  The Committee shall be responsible for 
the general operation and administration of the Plan and for carrying out the
provisions thereof. The Committee shall have discretion to interpret and
construe the provisions of the Plan.

6.2  General Powers of Administration.  All provisions set forth in the
Qualified Plan with respect to the administrative powers and duties of the
Committee, expenses of administration, and procedures for filing claims shall
also be applicable with respect to the Plan. The Committee shall be entitled to
rely conclusively upon all tables, valuations, certificates, opinions and
reports furnished by any actuary, accountant, controller, counsel or other
person employed or engaged by the Committee with respect to the Plan.


                                  ARTICLE VII
                           AMENDMENT OR TERMINATION

7.1  Amendment or Termination.  The Company intends the Plan to be permanent 
but reserves the right to amend or terminate the Plan when, in the sole
discretion of the Company, such amendment or termination is advisable. Any such
amendment or termination shall be made pursuant to a resolution of the Board and
shall be effective as of the date set forth in such resolution.

7.2  Effect of Amendment or Termination.  No amendment or termination of the 
Plan shall directly or indirectly reduce the balance of any Supplemental Account
held hereunder as of the effective date of such amendment or termination. Upon
termination of the Plan, disribution of amounts in a Participant's Supplemental
Account shall be made to him or his Beneficiary in the manner and at the time
described in Section 5.1 of the Plan. No additional credits of Supplemental
Before-Tax Deposits or Supplemental Matching Contributions shall be made to the
Supplemental Account of a Participant after termination of the Plan, but the
Company shall continue to credit gains and losses attributable to investments
made pursuant to Section 4.1 to such Supplemental Account until the balance of
such Account has been fully distributed to the Participant or his Beneficiary.


                                  ARTICLE VIII
                               GENERAL PROVISIONS

8.l  Participant's Rights Unsecured.  If and to the extent amounts allocated
hereunder to the Supplemental Accounts of Participants are contributed by the
Company to the Trust described in Section 4.1, benefits under the Plan shall be
payable pursuant to the Trust Agreement. Pursuant to the Trust Agreement, all
assets held thereunder
<PAGE>
 
shall remain subject to the general creditor of the Company. The Plan at all
times shall be entirely unfunded and no provision shall at any time be made with
respect to segregating any assets of the Company for payment of any benefits
hereunder. No Participant, Beneficiary or any other person shall have any
interest in any particular assets of the Company by reason of the right to
receive a benefit under the Plan and Trust Agreement and any such Participant,
Beneficiary or other person shall have only the rights of a general unsecured
creditor of the Company with respect to any rights under the Plan and Trust
Agreement.

8.2  General Conditions.  Except as otherwise expressly provided herein, all
terms and conditions of the Qualified Plan applicable to a Qualified Plan 
Before-Tax Deposit or a Qualified Plan Matching Contribution shall also be
applicable to a Supplemental Before-Tax Deposit or a Supplemental Matching
Contribution to be made hereunder. Any Qualified Plan Before-Tax Deposit or
Qualified Plan Matching Contribution, or any other contributions to be made
under the Qualified Plan, shall be made solely in accordance with the terms and
conditions of the Qualified Plan and nothing in this Plan shall operate or be
construed in any way to modify, amend or affect the terms and provisions of the
Qualified Plan.

8.3  No Guaranty of Benefits.  Nothing contained in the Plan shall constitute a 
guaranty by the Company or any other person or entity that the assets of the
Company will be sufficient to pay any benefit hereunder.

8.4  No Enlargement of Employee Rights.  No Participant shall have any right
to receive a distribution of contributions made under the Plan except in
accordance with the terms of the Plan.  Establishment of the Plan shall not
be construed to give any Participant the right to be retained in the service
of the Company.

8.5  Spendthrift Provision.  No interest of any person or entity in, or right 
to receive a distribution under, the Plan shall be subject in any manner to
sale, transfer, assignment, pledge, attachment, garnishment, or other alienation
or encumbrance of any kind; nor may such interest or right to receive a
distribution be taken, either voluntarily or involuntarily, for the satisfaction
of the debts of, or other obligations or claims against, such person or entity,
including claims for alimoney, support, separate maintenance and claims in
bankruptcy proceedings.

8.6  Applicable Law.  The Plan shall be construed and administered under the 
laws of the State of Illinois to the extent not inconsistent with the Employee
Retirement Income Security Act of l974.

8.7  Incapacity of Recipient.  If any benefit under the Plan shall be payable 
to a minor or a person not adjudicated incompetent but who, by reason of illness
or mental or physical disability, is, in the opinion of the Committee, unable to
properly manage his affairs, such benefit shall be paid in such of the following
ways as the Committee deems best: (a) to the person directly; (b) in the case of
a minor, to a custodian under any Uniform Gift to Minors Act for the person; or
(c) to the person's spouse, adult child or blood relative. Any benefit so
<PAGE>
 
paid shall be a complete discharge of any liability of the Company and the Plan
therefor.

8.8  Successors.  The Plan shall not be automatically terminated by a transfer 
or sale of assets of the Company or by the merger or consolidation of the
Company into or with any other corporation or other entity, but the Plan shall
be continued after such sale, merger or consolidation only if and to the extent
that the transferee, purchaser or successor entity agrees to continue the Plan.
In the event that the Plan is not continued by the transferee, purchaser or
successor entity, then the Plan shall terminate subject to the provisions of
Section 7.2.

8.9  Unclaimed Benefit.  Each Participant shall keep the Committee informed of
his current address and the current address of his designated Beneficiary.
Neither the Company nor the Committee shall be obligated to search for the
whereabouts of any person. If within three years after any benefit becomes due
under the Plan to or with respect to any Participant, the Committee is unable to
make payment because the identity or whereabouts of such person cannot be
ascertained notwithstanding the mailing of notice to any last known address or
addresses, the Committee shall make payment of such benefit as though the
Participant had died three years after the date such benefit became due. In the
event payment cannot be made at that time, the Participant's Supplemental 
Before-Tax Deposit Account and Supplemental Contribution Account shall be closed
out and disposed of in the same manner as forfeitures, but the amount thereof
shall be a continuing liability of the Plan. In the event it shall become
possible to make payment of the liability at a later date, the amount of the
liability shall be paid in accordance with the provisions of the Plan.

8.10  Limitations on Liability.  Notwithstanding any of the preceding provisions
of the Plan, neither the Company, any member of the Committee nor any individual
acting as an employee or agent of the Company or Committee shall be liable to
any Participant, former Participant, Beneficiary or any other person for any
claim, loss, liability or expense incurred in connection with the Plan.

8.11  Gender; Headings.  Words in the masculine gender shall include the
feminine and the singular shall include the plural, and vice versa, unless
qualified by the context.  Any headings used herein are included for ease of
reference only, and are not to be construed so as to alter the terms hereof.

IN WITNESS WHEREOF, The Northern Trust Company has caused this Plan to be signed
by its duly authorized officer as of the 31st day of December, 1995.

pertained to The Northern Trust Company Pension Plan were amended and
restated by The Restated Supplemental Pension Plan for Employees of The
Northern Trust Company, initially adopted effective September l, l989,
restated effective September l, l989 and amended effective December 2l, l993
and from time to time thereafter ("the Restated Supplemental Pension Plan").
The Northern Trust Company desires to further amend and restate The Restated
Supplemental Pension Plan, which has been established and is maintained by
The Northern Trust Company solely for the purpose of providing benefits for
certain employees of the Company who participate in The Northern Trust
Company Pension Plan and whose benefits under such plan are limited by the
restrictions on benefits imposed by Section 40l(a)(17) and Section 415 of
the Code.

Accordingly, effective January l, l996, The Northern Trust Company hereby
further amends and restates The Restated Supplemental Pension Plan pursuant
to the terms and provisions set forth below.

                                  ELIGIBILITY


2.1 Participant. An employee of the Company who is eligible in any Plan Year to
receive a Qualified Plan Pension Benefit, the amount of which is reduced by
reason of the application of the limitations on benefits imposed by either or
both of Section 40l(a)(17) and Section 415 of the Code on the Qualified Plan,
shall be a Participant and shall be eligible to receive a Supplemental Pension
Benefit for such Plan Year.


                                  ARTICLE III
                          SUPPLEMENTAL PENSION BENEFIT


3.1 Amount. The Supplemental Pension Benefit payable to an eligible Participant
shall be the difference between (a) the lump sum value of the Participant's
Qualified Plan Pension Benefit based on a straight life annuity over the
lifetime of the Participant only (i) after considering Code Section 401(a)(17)
and Section 415 restrictions, and (ii) compensation for any period of time
considered in computing such
<PAGE>
 
Benefit is determined including amounts of base salary and bonus earned with
respect to such period of time and deferred because of Internal Revenue Code
Section 162(m) limitations under the Northern Trust Corporation Annual
Performance Plan, and (b) the lump sum value of the Participant's Qualified Plan
Pension Benefit, based on the Participant's qualified joint and survivor lump
sum benefit (without consideration of such statutory restrictions).

(a)  If a Participant dies following his termination of employment with the
Company but prior to his Payment Entitlement Date the following rules apply:
(i) if he is survived by a Beneficiary who is living on his Payment
Entitlement Date, fifty percent (50%) of the amount that would have been
paid to the Participant on his Payment Date shall be paid in a single lump
sum on such Payment Date to his surviving Beneficiary, and no other benefit
shall be payable hereunder with respect to such Participant, or (ii) if he
is not survived by a Beneficiary who is living on his Payment Entitlement
Date, no benefit shall be payable hereunder with respect to such
Participant.

(b)  If a Participant dies following his termination of employment with the
Company but after his Payment Entitlement Date the following rules apply:
(i) if he is survived by a Beneficiary who is living on the Payment Date,
l00% of the amount that would have been paid to the Participant on his
Payment Date shall be paid in a single lump sum on such Payment Date to his
Beneficiary, and no other benefit shall be payable hereunder with respect to
such Participant, or (ii) if he is not survived by a Beneficiary who is
living on his Payment Date, the full benefit shall be payable to his estate.

(c)  In the event that a Participant's entire Qualified Plan Pension Benefit
has been distributed due to the payment of a qualified domestic relations
order (QDRO), the Participant will be entitled to the Supplemental Pension
Benefit to which he or she would have been entitled, calculated without
regard to the QDRO.  The Participant's Supplemental Pension Benefit will not
replace any amount actually paid to an alternative payee pursuant to the
QDRO.

(d)  Notwithstanding anything to the contrary contained herein, the annual 
amount to be paid from the Plan in the year of a Participant's termination shall
be limited to an amount which will not cause the total amount of compensation
received from the Company and the amount paid from the Plan to exceed the
maximum amount deductible by the Company under Code Section 162(m). Any amount
which is not paid as the result of this limitation shall be transferred to the
Supplemental Thrift-Incentive Plan for Employees of The Northern Trust Company
as of the end of the month next following the month in which such amount would
have been paid, but for such limitation. Amounts so transferred shall be paid in
subsequent years, to the extent permissible under this limitation, to the
Participant, or in the event of the Participant's death, to the Participant's
Beneficiary, if he or she survives the Participant, and if not, to the
Participant's estate.

3.2  Vesting of Benefit. Each Participant shall vest in his Supplemental Pension
Benefit in accordance with the vesting schedule applicable to his Qualified Plan
Pension Benefit set forth in the
<PAGE>
 
Qualified Plan. Notwithstanding the preceding sentence or any other provision of
the Plan, each Participant shall become fully vested in his Supplemental Pension
Benefit on the effective date of a Change-in-Control.

3.3  Form of Benefit. The Supplemental Pension Benefit of a Participant whose
employment with the Company terminates for any reason shall be paid in a single
lump sum, which shall be equal to the amount calculated pursuant to Section 3.1
above, as determined by the same actuarial adjustments as those specified in the
Qualified Plan with respect to determination of the amount of the Qualified Plan
Pension Benefit or Qualified Plan Survivor Benefit.

3.4  Commencement of Benefit. Payment to a Participant of his Supplemental
Pension Benefit shall be made on his Payment Date. If such Benefit is paid prior
to the Participant's Normal Retirement Date, it shall be adjusted to reflect
such early payment as determined by the same early retirement adjustment factors
as are specified in the Qualified Plan with respect to the adjustment of the
Qualified Plan Pension Benefit for early commencement.

3.5  Grandfather Provision. Notwithstanding anything to the contrary contained
herein, any Participant who commenced receiving payment of a Supplemental
Pension Benefit hereunder in the form of an annuity prior to September l, l989,
pursuant to the terms of the Plan on the date payment of such Benefit commenced,
shall continue to receive such payments from and after September l, l989 in the
form of such annuity.

Notwithstanding anything to the contrary contained herein, any Beneficiary who
commenced receiving payment of a Supplemental Survivor Benefit hereunder in the
form of an annuity prior to January 1, 1995, pursuant to the terms of the Plan
on the date payment of such Benefit commenced, shall continue to receive such
payments from and after January l, l995 in the form of such annuity.


                                  ARTICLE IV
                         SUPPLEMENTAL SURVIVOR BENEFIT


4.1  Amount. If a Participant dies prior to termination of employment under
circumstances in which a Qualified Plan Survivor Benefit is payable to his
Beneficiary, then a Supplemental Survivor Benefit is payable to his Beneficiary
as hereinafter provided. The amount of the Supplemental Survivor Benefit payable
to a Participant's Beneficiary shall be equal to the difference between (a) and
(b) below:

(a)  the lump sum value of the Qualified Plan Survivor Benefit to which the
Beneficiary would have been entitled under the Qualified Plan if (i) such
Benefit were computed without giving effect to the limitations on benefits
imposed by Sections 401(a)(17) and 415 of the Code, and (ii) Compensation
for any period of time considered in computing such Benefit was determined
including amounts of base salary and bonus which are eligible for computing
such benefit under the Qualified Plan;
<PAGE>
 
(b)  the lump sum value of the Qualified Plan Survivor Benefit actually payable
to the Beneficiary under the Qualified Plan.

4.2  Form and Commencement of Benefit. If a Supplemental Survivor Benefit shall
be payable hereunder, such Benefit shall be payable in one lump sum payment, to
be made according to the schedule for payment of a Qualified Plan Survivor
Benefit as though it had commenced immediately.

                                  ARTICLE V
                          ADMINISTRATION OF THE PLAN

5.1  Administration by the Committee. The Committee shall be responsible for the
general operation and administration of the Plan and for carrying out the
provisions thereof. The Committe shall have discretion to interpret and construe
the provisions of the Plan.

5.2  General Powers of Administration. All provisions set forth in the Qualified
Plan with respect to the administrative powers and duties of the Committee,
expenses of administration, and procedures for filing claims shall also be
applicable with respect to the Plan. The Committee shall be entitled to rely
conclusively upon all tables, valuations, certificates, opinions and reports
furnished by any actuary, accountant, controller, counsel or other person
employed or engaged by the Committee with respect to the Plan.


                                  ARTICLE VI
                           AMENDMENT OR TERMINATION

6.1  Amendment or Termination. The Company intends the Plan to be permanent but
reserves the right to amend or terminate the Plan when, in the sole discretion
of the Company, such amendment or termination is advisable. Any such amendment
or termination shall be made pursuant to a resolution of the Board and shall be
effective as of the date set forth in such resolution.

6.2  Effect of Amendment or Termination. No amendment or termination of the Plan
shall directly or indirectly deprive any current or former Participant or
Beneficiary of all or any portion of any Supplemental Pension Benefit or
Supplemental Survivor Benefit, payment of which has commenced prior to the
effective date of such amendment or termination, or that would be payable if the
Participant terminated employment for any reason, including death on such
effective date.


                                  ARTICLE VII
                              GENERAL PROVISIONS

7.1  Funding. The Company may contribute amounts to fund the benefits under the
Plan to a trust ("Trust") established pursuant to a trust agreement between the
Company and Harris Trust & Savings Bank, a bank organized and existing under the
laws of the State of Illinois, as trustee ("Trust Agreement"). If and to the
extent amounts are contributed hereunder by the Company to the Trust, benefits
under the
<PAGE>
 
Plan shall be payable pursuant to the Trust Agreement. Pursuant to the Trust
Agreement, all assets held thereunder shall remain subject to the general
creditors of the Company. The Plan at all times shall be entirely unfunded and
no provision shall at any time be made with respect to segregating any assets of
the Company for payment of any benefits hereunder. No Participant, Beneficiary
or any other person shall have any interest in any particular assets of the
Company by reason of right to receive a benefit under the Plan and Trust
Agreement and any such Participant, Beneficiary or other person shall have only
the rights of a general unsecured creditor of the Company with respect to any
rights under the Plan and Trust Agreement.

7.2  General Conditions. Except as otherwise expressly provided herein, all
terms and conditions of the Qualified Plan applicable to a Qualified Plan
Pension Benefit or a Qualified Plan Survivor Benefit shall also be applicable to
a Supplemental Pension Benefit or a Supplemental Survivor Benefit payable
hereunder. Any Qualified Plan Pension Benefit or Qualified Plan Survivor
benefit, or any other benefit payable under the Qualified Plan, shall be paid
solely in accordance with the terms and conditions of the Qualified Plan and
nothing in the Plan shall operate or be construed in any way to modify, amend or
affect the terms and provisions of the Qualified Plan.

7.3  No Guaranty of Benefits. Nothing contained in the Plan shall constitute a
guaranty by the Company or any other entity or person that the assets of the
Company will be sufficient to pay any benefit hereunder.

7.4  No Enlargement of Employee Rights. No Participant or Beneficiary shall have
any right to a benefit under the Plan except in accordance with the terms of the
Plan. Establishment of the Plan shall not be construed to give any Participant
the right to be retained in the service of the Company.

7.5  Spendthrift Provision. No interest of any person or entity in, or right to
receive a distribution under, the Plan shall be subject in any manner to sale,
transfer, assignment, pledge, attachment, garnishment, or other alienation or
encumbrance of any kind; nor may such interest or right to receive a
distribution be taken, either voluntarily or involuntarily, for the satisfaction
of the debts of, or other obligations or claims against, such person or entity,
including claims for alimoney, support, separate maintenance and claims in
bankruptcy proceedings.

7.6  Applicable Law. The Plan shall be construed and administered under the laws
of the State of Illinois to the extent not inconsistent with the Employee
Retirement Income Security Act of l974.

7.7  Incapacity of Recipient. If any benefit under the Plan shall be payable to
a minor or a person not adjudicated incompetent but who, by reason of illness or
mental or physical disability, is, in the opinion of the Committee, unable to
properly manage his affairs, such benefit shall be paid in such of the following
ways as the Committee deems best: (a) to the person directly; (b) in the case of
a minor, to a custodian under any Uniform Gift to Minors Act for the person; or
(c)
<PAGE>
 
to the person's spouse, adult child or blood relative. Any benefit so paid shall
be a complete discharge of any liability of the Company and Plan therefor.

7.8  Successors. The Plan shall not be automatically terminated by a transfer or
sale of assets of the Company or by the merger or consolidation of the Company
into or with any other corporation or other entity, but the Plan shall be
continued after such sale, merger or consolidation only if and to the extent
that the transferee, purchaser or successor entity agrees to continue the Plan.
In the event that the Plan is not continued by the transferee, purchaser or
successor entity, then the Plan shall terminate subject to the provisions of
Section 6.2.

7.9  Unclaimed Benefit. Each Participant shall keep the Committee informed of
his current address and the current address of his Beneficiary. Neither the
Company nor the Committee shall be obligated to search for the whereabouts of
any person. If the location of a Participant is not made known to the Committee
within three (3) years after the date on which payment of the Participant's
Supplemental Pension Benefit may first be made, payment may be made as though
the Participant had died at the end of the three-year period. If, within one
additional year after such three-year period has elapsed, or within three years
after the actual death of a Participant, neither the Company nor the Committee
is able to locate any Beneficiary of the Participant, then the Company shall
have no further obligation to pay any benefit hereunder to such Participant or
Beneficiary and such benefit shall be irrevocably forfeited; provided, however,
that if the Participant or Beneficiary makes a valid claim for any benefit that
has been so forfeited, the forfeited benefit shall be reinstated.

7.10  Limitations on Liability. Notwithstanding any of the preceding provisions
of the Plan, neither the Company, any member of the Committee, nor any
individual acting as an employee or agent of the Company or Committee shall be
liable to any Participant, former Participant, Beneficiary or any other person
for any claim, loss, liability or expense incurred in connection with the Plan.

7.11  Gender; Headings. Words in the masculine gender shall include the feminine
and the singular shall include the plural, and vice versa, unless qualified by
the context. Any headings used herein are included for ease of reference only,
and are not to be construed so as to alter the terms hereof.

IN WITNESS WHEREOF, The Northern Trust Company has caused this Plan to be signed
by its duly authorized officer as of the 31st day of December, 1995.

     1.   Amendment of Lease. Paragraph 5(B)(i) of the Lease is hereby deleted, 
and the following inserted in lieu thereof:

          "(i) For the Base Year (and first full Lease Year if the Base Year

     for the month in which this Lease was executed, and (b) $1.00 per RSF; and"

     2.   Legal Effect. As amended herein, the Lease shall remain in full force

whatsoever against Trustee personally; and in particular, without limiting the

indebtedness accruing hereunder or to perform any covenant, either express or 
implied, herein contained, or to keep, preserve, or sequester any property and 
all personal liability of every sort, if any, is hereby expressly waived by said

     3.  The following is hereby inserted into the Lease as Paragraph 1G:

     "G.  "Lower Mid-Rise Section" shall mean the floors of the Building

     accordance with Paragraph 2C hereof, any additional work in the Premises
     over and above that specified in Paragraph 2A above, subject to the terms
     and conditions of this Paragraph 2B. If included in Tenant's plans and
     specifications, Landlord will supply and install the items described on
     Exhibit C attached hereto and made a part hereof (the "Building Standard
     Work") in the Premises in Landlord's standard manner. Landlord shall

     credit, if any, attributable to all such work shall be divided between
     Landlord and Tenant in the proportion in which each bears the cost of all
     such work. All such cost calculations shall be based on the RSF actually
     included in the Premises on the Commencement Date (as hereinafter defined).
     Any portion of the Allowance not applied to defray the cost of such
     additional work shall, at Tenant's option, either (i) be applied in payment

     Base Year multiplied by the percentage change (positive or negative) of the
     CPI for the month in which the Term of this lease 

                                      -3-

     Lease Year the amount of the annual Rent Adjustment made by reason of
     changes in the CPI shall not exceed three percent (3%) of the adjusted
     Annual Base Rent for the immediately preceding Lease Year. The limitation
     set forth in the immediately preceding sentence shall not affect

     7.  Paragraph 16 of the Lease is hereby deleted, and the following inserted
in lieu thereof:

     "16. ASSIGNMENT AND SUBLETTING. Tenant may assign or transfer this Lease or
     any interest under it, and may sublet the Premises or any part thereof to
     (i) an entity controlling, controlled by or under common control with
     Tenant or to any successor to Tenant by merger or acquisition (any such
     entity or successor being sometimes hereafter referred to as an "affiliate"
     of Tenant); or (ii) any financially responsible party approved by Landlord,
     (which approval shall not be unreasonably withheld, denied or delayed)
     whose stated use of the Premises will not result in a breach of an
     exclusive use provision for space in the Building theretofore granted by
     Landlord (subject to Landlord's written right to recapture as hereafter set
     forth). Not less than thirty (30) days prior to the proposed commencement
     of such assignment or sublease to a party other than an affiliate of
     Tenant, Tenant shall give Landlord written notice of the proposed
     assignment or sublease which notice shall contain the name of the proposed
     assignee or sublessee and proposed principal terms thereof and shall be
     accompanied by the last available financial statement of such proposed
     assignee of sublessee. Within ten (10) days of Landlord's receipt of such
     written notice and financial statement Landlord shall approve or disapprove
     of the proposed assignee or sublessee, or if such proposed transfer is (i)
     a sublease to other than an affiliate (A) for more than three (3) floors of
     the Premises, and (B) for longer than either five (5) years or seventy-five
     (75%) percent of the remainder of the Term, whichever is less, or during
     the first three (3) years of the Term, or (ii) an assignment to other than
     an affiliate, Landlord may terminate this Lease as to such proposed
     subleased space in the case of a proposed sublease, or all of the Premises
     in

                                      -4-
<PAGE>
 
     the case of a proposed assignment. If Landlord does not terminate as
     aforesaid, Landlord may withhold its consent to such proposed assignee or
     sublessee only for reasonable reasons related to the financial
     responsibility of the proposed party but such disapproval may not be given
     because (a) vacant space exists in the Building, (b) such proposed assignee
     or sublessee is a tenant in the Building or has discussed tenancy in the
     Building or any other building with the Landlord, or (c) the price or
     rental rate of the proposed assignment or sublease. Failure of Landlord to
     respond within such ten (10) day period shall constitute Landlord's
     approval of such proposed assignee or sublessee. Upon the assignment of all
     of Tenant's interest in this Lease to an assignee wherein the Rent to be
     paid by the assignee equals, or exceeds the Rent payable under this Lease,
     which assignment is approved by Landlord as aforesaid (including an
     assignment to an affiliate, if such an affiliate is approved by Landlord,
     although Tenant is not required to obtain approval of an assignment to an
     affiliate [but if Tenant elects not to, it shall not be relieved of its
     obligations under this Lease]), and delivery of a written assumption of
     this Lease and the obligations hereunder by such assignee, Tenant shall be
     relieved of all further obligations under this Lease except the obligation
     to pay to the Landlord excess rent as provided in the next paragraph.

     If Tenant shall assign or transfer its interest in this Lease or sublet the
     Premises pursuant to this Section 16, then Tenant shall pay to Landlord as
     additional rent immediately upon receipt under any such assignment or in
     the case of a sublease on the first day of each month during the term of
     any such sublease, one-half (1/2) of the excess of all rent over the sum of
     (x) Base Rent plus Rent Adjustment then payable to Landlord under this
     Lease for said month (or if only a portion of the Premises is being sublet,
     the portion of the Base Rent plus Rent Adjustment then payable to Landlord
     under this Lease for said month which is allocable on a square foot basis
     to the space sublet) plus (y) an amount equal to the quotient of "Tenant's
     Costs" as hereinafter defined incurred by Tenant in connection with said
     sublease divided by the number of months in the term of such sublease. As
     used in the preceding sentence, Tenant's Costs for such assignment or
     sublease shall include the unamortized amount of improvements made at
     Tenant's expense, alterations to the Premises in connection with such
     assignment or sublease made at Tenant's expense, and leasing commissions,
     rent concessions, advertising cost, and legal expenses in connection with
     such assignment or sublease."

     8. Paragraph 27 is hereby deleted and the following inserted in lieu 
thereof:

                                      -5-

     approximately 56 parking spaces located in the Building's underground
     garage. Tenant shall have the right to lease for the full term Tenant's
     Proportionate Share of such parking spaces (which share shall be not less
     than 12 spaces), at regular annual Building rates therefor, and in
     locations designated by Landlord, such right to remain exercisable until
     the Commencement Date, and to include the right to sublease to any
     sublessee of space in the Premises or to employees or partners of such
     sublessees or of Tenant. In addition, Tenant shall be entitled, at regular
     annual Building rates therefor, to any parking spaces which were rented by
     the immediately preceding tenants in space added to the Premises after the
     Commencement Date. Tenant may give up such parking spaces, or any thereof,
     so leased at any time(s) on not less than sixty (60) days' notice and shall
     not have any rights for the number of spaces so given up at any time
     thereafter. Notwithstanding the immediately preceding sentence, Tenant
     shall have the right to sublease any parking spaces leased hereunder to
     parties (including, but not limited to, car rental entities) selected by
     Tenant, provided that (i) the rent charged for any parking spaces so
     subleased is less than or equal to the rent charged Tenant by Landlord
     therefor, and (ii) the use of the subleased parking spaces by the
     sublessees thereof does not interfere with Landlord's operation of the
     garage or use of the garage by other parking lessees."

     9.  Paragraphs 30A and 30B of the Lease are hereby deleted and the 
following inserted in lieu thereof:

     Sections 1F and 1G of this Lease) (the "6th Year Option Floors"). Tenant
     may lease any or all of the 6th Year Option Floors commencing at some point
     during the 6th Lease Year as determined by Landlord.

     B.  Landlord hereby grants to Tenant the further option to lease an
     additional three floors contiguous to the Premises designated by Landlord
     and located in the Low-rise Section or Lower Mid-rise Section of the
     Building (as defined in Sections 1F and 1G of this Lease) ("11th Year
     Option Floors"), which Option may be exercised whether or not Tenant has
     taken any, all or none of the 6th Year Option Floors. Tenant may lease any
     or all of the 11th Year Option Floors commencing at some point during the
     11th Lease Year as determined by Landlord."

     Lower Mid-rise Section of the Building (as defined in Section 1G hereof).
     Landlord shall include in any Lease of space in the Low-rise Section of the
     Building or the Lower Mid-rise Section of the Building (other than a Lease
     to American International Group or any affiliate thereof or entity related
     thereto) a provision to the effect that in the event the tenant thereunder
     attempts to assign such Lease, or attempts to sublease substantially all of
     the space demised thereby for a term of either five (5) years or seventy-
     five (75%) percent of the remaining term of such lease, whichever is less,
     Landlord may terminate such lease and recapture the space demised thereby.
     Any space so recaptured by Landlord shall be subject to the provisions of
     this Paragraph 31, and prior to declining to recapture such space, Landlord
     will offer such space to Tenant in accordance with the provisions of this
     Paragraph 31."

     12.  The first sentence of Paragraph 33C of the Lease is hereby deleted

<PAGE>
 
     pedestrian bridge whose slant and floor pitch will meet commonly accepted
     standards for pedestrian traffic. Provided that (i) Tenant complies with
     the provisions of Paragraph 8B of the Lease (except for Landlord's consent
     to construction of a bridge, which consent is hereby given provided Tenant
     complies with the provisions of this Paragraph 38, (ii) the design of each

     reduction of the cost to Tenant of constructing one or more bridges
     pursuant to this Section 38."

     cafeteria by written notice to Landlord, and shall specify in such notice
     (i) the proposed size of the cafeteria, and (ii) the maximum number of
     persons who will be permitted to occupy the cafeteria at any time. Landlord
     and Tenant acknowledge that as a result of Tenant's election to construct a
     cafeteria, Landlord may have to make certain modifications to its Base
     Building plans and specifications to accommodate Tenant's cafeteria use of
     a portion of the Premises, including provision for such items as one or
     more additional exit stairways down from the floor on which the cafeteria
     is located. The area of any floor space (whether within or outside of the
     Premises) within the Building which is rendered unusable by reason of the
     use of a portion of the Premises as a cafeteria, including the floor area
     occupied by any additional exit stairways required to be constructed in

     Building previously prepared for Landlord, or (ii) increases in the cost of
     constructing the Building occasioned by the use of a portion of the
     Premises as a cafeteria (whether or not included in the direct cost of the
     installation of the cafeteria), shall be deducted from the Allowance
     granted Tenant pursuant to Section 2B hereof or paid by Tenant as provided
     in Section 2E hereof."

     B. Humidification. Landlord shall install a humidification system in the
     Building serving the Premises (including, without limiting the generality
     of the foregoing, the 6th year option floors, the 11th year option floors
     and the right of first refusal floors described in Paragraph 31 hereof)
     capable of maintaining a relative humidity level in the Premises of thirty
     percent (30%). The cost of installing such a humidification system for the

     entire Building, the pro rata share of the cost of such a system allocable
     to the Premises) shall be deducted from the Allowance granted Tenant
     pursuant to Section 2B hereof or paid by Tenant as provided in Section 2E
     hereof.

     C. Sprinkler Heads. Sprinkler heads, in the quantity provided for in the

     attached hereto as Exhibit C, shall be positioned within the Premises as
     provided in the Plans as part of the Building Standard Work; provided,
     however, that the cost of any additional sprinkler heads required by the
     Plans or by applicable law in excess of the building standard quantity
     shall be deducted from the Allowance granted Tenant pursuant to Section 2B
     hereof or paid by Tenant as provided in Section 2E hereof.

     D.  Underfloor Duct System.  Landlord shall install an underfloor duct
     system (the "Duct System") throughout the Premises, including, without
     limiting the generality of the foregoing, the 6th year option floors, the

     Paragraph 31 hereof. The design of the Duct System and the plans and
     specifications therefor shall be submitted to Tenant for its approval in
     accordance with the Schedule. Tenant shall have the right to approve the
     subcontractors for, and to require competitive bids for, the installation
     of the Duct System in accordance with the provisions of Section 2F hereof.

     borne and paid by Landlord; the balance of such costs and expenses
     associated with the design and installation of the Duct System shall be
     deducted from the Allowance granted Tenant pursuant to Section 2B hereof or
     paid by Tenant as provided in Section 2E hereof. In the event this Lease is
     terminated pursuant to Section 17 hereof, that portion of the cost of the
     Duct System so deducted from the Allowance or paid by Tenant shall be
     included in the Tenant Casualty Amount. Alterations to that portion of the
     interior electrical system for the Premises installed in the Duct System
     which do not affect the ceilings, the HVAC system, or any other system
     servicing the Premises or any other portion of the Building, shall not
     require the consent of Landlord hereunder. The wiring installed in the Duct
     System shall, for purposes of Section 15C of the Lease, be deemed to be
     equipment of Tenant that Landlord and Tenant have agreed may be removed
     from the Premises by Tenant upon the termination of this Lease.

     E.  Secured Vertical Shaft.  Landlord will install, for the exclusive use
     of Tenant, a secured vertical shaft with dimensions of not less than
     eighteen (18) inches by twenty-

                                     -10-

     four (24) inches accessible from each floor in the Low-Rise Section and the
     Lower Mid-Rise Section of the Building. The location of such vertical shaft
     shall be agreed upon by Landlord and Tenant as provided in the Schedule.
     The area of any floor space (whether within or outside of the Premises)
     within the Building which is rendered unusable by reason of the
     installation of such vertical shaft shall be included in the RSF of the
     Premises. All costs and expenses associated with the design and
     installation of such vertical shaft, including without limitation (i)
     changes or modifications to plans for the Building previously prepared for
     Landlord, or (ii) increases in the cost of constructing the Building
     occasioned by the installation of the vertical shaft but not included in
     the direct cost of the installation of the vertical shaft, shall be
     deducted from the Allowance granted Tenant pursuant to Section 2B hereof or
     paid by Tenant as provided in Section 2E hereof."
     
     15.  The following paragraph is hereby inserted in the Lease as Section 41:

     "41.  TENANT CONCESSION ACCOUNT.  Upon the opening of the construction loan
     for the Building, Landlord shall establish a non-interest bearing account
     with The Northern Trust Company, or such other bank as may be designated by
     Tenant, and shall deposit the sum of Three Million Dollars ($3,000,000)
     therein. The funds held in such account shall be used to pay any and all
     expenses and obligations of Tenant (including without limitation rent
     payments) under that certain Lease dated November 27, 1987 by and between
     Harris Trust and Savings Bank Trust No. 40649, as Landlord, and Tenant, as
     tenant. Landlord shall cause any such expenses to be promptly paid from
     such account upon the submission to Landlord by Tenant of a statement,
     invoice or other written request of Tenant that such payment be made;
     provided, however, that nothing in this Paragraph 41 shall be deemed or
     construed as the assumption by Landlord of the obligations of Tenant as
     tenant under the Lease described in this Section 41."

     16.  The following paragraph is hereby inserted in the Lease as Section 42:

     "42.  CONSTRUCTION SUPERVISION SERVICES.

     A.  Landlord and Tenant acknowledge that prior to and during the
     construction of the Premises, Landlord will provide Tenant with certain
     construction supervision services including review and approval of the
     Plans and supervision of the construction of the Premises and the
     installation of the tenant improvements for the Premises; in the event
     that, after completion of the Premises, Tenant

                                     -11-
<PAGE>
 
     determines to make alterations or additions to the Premises as provided in
     Section 8B hereof, Landlord shall also provide construction supervision
     services in connection with such alterations or additions.

     B. Prior to the issuance of the building permit for the construction of the
     Premises, such construction supervision services shall be performed by
     Landlord and its employees and representatives at no cost to Tenant. After
     the issuance of the building permit for the Premises, Landlord shall charge
     Tenant a reasonable fee for such construction supervision services;
     provided, however, that the total fees payable to Landlord by Tenant for
     such construction supervision services shall not exceed one and one-half
     percent (1 1/2%) of the cost of construction of the Premises and the
     installation of the tenant improvements therein. In the event that an
     affiliate of Landlord shall act as the general contractor for the
     construction of the Premises, the fee for construction supervision services
     payable pursuant to this Section 42B shall be in addition to, and not in
     lieu of, the fee payable to such general contractor.

     C. In the event that, after the completion of the Premises, Tenant
     determines to make alterations or additions to the Premises as provided in
     Section 8B, Landlord shall charge Tenant a reasonable fee for construction
     supervision services associated with such alterations or additions;
     provided, however, that the total fees payable to Landlord by Tenant for
     such construction supervision services shall not exceed fifteen percent
     (15%) of the cost of construction of such alterations or additions. In the
     event that an affiliate of Landlord shall act as the general contractor for
     such alterations or additions, the fee for construction supervision
     services payable pursuant to this Section 42C shall be in addition to, and
     not in lieu of, the fee payable to such general contractor. In addition, if
     at any time Tenant requests additional or special services such as
     cleaning, after hours air conditioning, or the like, Landlord's fee for
     furnishing these services shall not exceed 15% of the cost of furnishing
     such services."

     17. The following paragraph is hereby inserted in the Lease as Paragraph 
43:

     "43. RIGHT OF FIRST OFFER UPON SALE OF THE BUILDING.

     A.  Unsolicited Offer from Third Party.

          (i) In the event Landlord shall receive (other than pursuant to
     Subparagraph 43C) an offer from a third party to purchase the Building and
     Land (hereinafter in this Paragraph 43 jointly referred to as "Real
     Estate") which

                                     -12-
<PAGE>
 
     Landlord desires to accept ("Third Party Offer"), Landlord shall by written
     notice to Tenant (accompanied by a true, correct and complete copy of the
     Third Party Offer) offer the same Real Estate for sale to Tenant ("Tenant
     Offer") for the same price, on the same terms and subject to the same
     conditions as is set forth in the third Party Offer.

          (ii) Tenant shall have a period of fifteen (15) days after delivery of
     the Tenant Offer in which to deliver to Landlord a written notice of
     Tenant's election to purchase the Real Estate for the purchase price, on
     the terms and subject to the conditions set forth in the Tenant Offer;
     provided, however, if within said 15-day period, Tenant delivers to
     Landlord written approval by Tenant's management committee, subject to
     appraisal and board approval, that Tenant will elect to purchase the Real
     Estate for the purchase price and on the terms and conditions set forth in
     the Tenant Offer, such 15-day period shall be extended by an additional
     period of fifteen (15) days. During said 15-day or 30-day period, as the
     case may be, Landlord shall not accept the Third Party Offer unless its
     acceptance shall be expressly subject to the rights of Tenant under this
     Paragraph 43A. If Tenant elects to accept the Tenant Offer, it shall submit
     to Landlord within said 15-day or 30-day period, as the case may be, a
     purchase and sale agreement executed by Tenant pursuant to which Tenant
     shall agree to purchase the Real Estate for the price, upon the terms and
     subject to the conditions provided in the Tenant Offer, which purchase and
     sale agreement shall be accompanied by an earnest money deposit if and to
     the extent so provided in the Third Party Offer, whereupon Landlord shall
     promptly execute and return to Tenant a counterpart of said purchase and
     sale agreement.

          (iii) If Tenant fails to deliver such notice of acceptance, executed
     purchase agreement and earnest money within said 15-day or 30-day period,
     as the case may be, then, in such event, Tenant's rights under
     Subparagraphs 43A and 43B shall terminate and be of no further force and
     effect, and Landlord may sell the Real Estate in accordance with the Third
     Party Offer and consummate a sale in accordance with the Third Party Offer
     free of any rights of Tenant under this Paragraph 43; provided, however, if
     Landlord fails to consummate a sale of the Real Estate before the later of
     (a) the date set for closing in the Tenant Offer, or (b) six months after
     the expiration and termination of Tenant's rights under this Subparagraph
     43A, then, unless Landlord shall have complied with the procedure set forth
     in Paragraph 43B, in which event each of Landlord and Tenant shall have
     only the rights set forth in said Paragraph 43B, Tenant's rights under this
     Subparagraph 43A shall be reinvested.

                                     -13-
<PAGE>
 
     B. Offering of the Real Estate for Sale.

          (i) In the event that, at any time during the term of this Lease, 
Landlord intends to sell the Real Estate, Landlord shall deliver written notice 
of its intention ("Notice of Intent") to Tenant in advance of any such offering.
Tenant shall have a period of thirty (30) days following delivery of the Notice 
of Intent to Tenant within which to advise Landlord by written notice ("Notice 
of Interest") that Tenant is interesting in negotiating with Landlord for the 
purchase the Real Estate, and up to 60 days following delivery of the Notice of 
Intent within which to execute a real estate purchase contract for the Real 
Estate with Purchaser, and during said 60-day period: (a) Landlord shall refrain
from actively marketing the Real Estate for sale to a third party; (b) Landlord 
shall furnish to Tenant such information as Tenant may reasonably request 
relative to the Real Estate, including the status of title and a then current 
operating statement and rent roll, copies of all tenant leases and a preliminary
title report for the Real Estate; and (c) Landlord and Tenant shall attempt in 
good faith to agree upon terms and conditions upon which Landlord shall sell and
Tenant shall purchase the Real Estate, and to memorialize such agreement in a 
real estate sale contract for the Real Estate.

          (ii) If (a) Tenant fails to deliver the Notice of Interest within 
thirty (30) days following delivery of the Notice of Intent, or (b) Landlord and
Tenant are unable to agree for any reason upon the terms upon which Landlord 
shall sell and Tenant shall purchase the Real Estate within sixty (60) days 
following delivery of the Notice of Intent, or (c) Landlord and Tenant are 
unable to agree for any reason upon the terms of a real estate sale contract for
the Real Estate within sixty (60) days following delivery of the Notice of 
Intent, or (d) Tenant fails to execute and deliver the negotiated real estate 
sale contract for the Real Estate, together with the earnest money required 
thereunder, within sixty (60) days following delivery of the Notice of Intent, 
Landlord may within one hundred eighty (180) days thereafter offer the Real 
Estate for sale in accordance with subparagraph (iii) below. If Landlord fails 
to offer the Real Estate for sale in accordance with subparagraph 3 below within
such 180-day period then, subject to Paragraph 43A, Tenant's rights under this 
Paragraph 43B shall be reinstated.

     (iii) Prior to offering to sell the Real Estate to a third party, Landlord 
shall advise Tenant of the price and the other terms and conditions upon which 
Landlord intends to offer the Real Estate for sale ("Offered Terms") by

                                     -14-

<PAGE>
 
     delivery to Tenant of a real estate sale contract for the Real Estate
     setting forth Offered Terms, whereupon Tenant may elect, within three (3)
     days after receipt of such notice from Landlord, to purchase the Building
     upon the Offered Terms by executing and delivering to Landlord such real
     estate sale contract containing the Offered Terms, together with the
     earnest money required thereunder. If Tenant shall fail to timely elect to
     purchase the Building on the Offered Terms aforesaid, Tenant's rights under
     Subparagraph 43A and Subparagraph 43B shall terminate and be of no further
     force and effect and Landlord may offer the Real Estate for sale and
     contract for and consummate a sale of the Real Estate (whether upon the
     Offered Terms or otherwise) free of any rights of Tenant under this
     Paragraph 43; provided, however, if Landlord fails to consummate a sale of
     the Real Estate within twenty-four (24) months after the expiration and
     termination of Tenant's rights under this Subparagraph 43B, then, subject
     to Subparagraph 43A, Tenant's rights under this Subparagraph 43B shall be
     reinstated.

     C. The restrictions set forth in this Paragraph 43 shall not apply to a
     proposed sale of the Real Estate to American International Group, or any
     other joint venture partner in the ownership of the Building, or mortgage
     of the Real Estate having a participating mortgage or similar right to
     share in profits derived from the sale or refinancing of the Real Estate
     (each such party being hereinafter referred to as a "Participant"), or any
     entity controlled by, controlling or under common control with any
     Participant, or to any sale or transfer between any of any Participant, Lee
     Miglin and J. Paul Beitler or any affiliates thereof."

     18. The following paragraph is hereby inserted in the Lease as Section 44:

     "44. LEASING COMMISSIONS. Landlord and Tenant acknowledge that Scribcor,
     Inc. ("Scribcor") has acted as an intermediary in connection with this
     Lease and the lease of space in the Building from Landlord to Tenant
     hereunder. Any and all leasing commissions payable to Scribcor on account
     of the lease of the Original Premises from Landlord to Tenant shall be paid
     by Landlord. The leasing commissions payable to Scribcor in connection with
     the lease by Tenant of the Additional Premises total $581,700, as set forth
     in a letter dated April 21, 1987, a copy of which is attached hereto as
     Exhibit 1; Tenant hereby assumes any and all liability for the leasing
     commissions payable to Scribcor on account of Tenant's lease of the
     Additional Premises, and agrees to indemnify Landlord and hold Landlord

                                     -15-

<PAGE>
 
     harmless from and against any and all liability which may be asserted or
     recovered against landlord by Scribcor for leasing commissions arising out
     of Tenant's lease of the Additional Premises, including reasonable
     attorneys fees."

          19. Neither Tenant, nor Landlord and its beneficiaries shall issue any
     press release or make any other public disclosure or announcement of the
     transactions which are the subject of this Amendment without the prior
     written consent of the other party hereto, which consent shall not be
     unreasonably withheld or delayed; provided, however, that the foregoing
     shall not be construed to limit or impair the rights of Landlord or its
     beneficiary to disclose the transactions which are the subject of this
     Amendment to prospective lenders, attorneys, accountants and other parties
     consulted or retained by Landlord in connection with the development of the
     Building.

          20. As amended herein, the Lease shall remain in full force and effect
     and, except as expressly amended herein, shall be unaffected hereby. In the
     event of any conflict between the provisions of this Amendment and the
     provisions of the Lease, the provisions of this Amendment shall control.

          21. This Second Amendment to Agreement of Lease is executed by
     American National Bank and Trust Company, not personally, but in the
     exercise of the power and authority conferred upon and vested in it as
     Trustee. It is expressly understood and agreed that nothing herein shall be
     construed as creating any liability whatsoever against Trustee personally;
     and in particular, without limiting the generality of the foregoing, there
     shall be no personal liability to pay any indebtedness accruing hereunder
     or to perform any covenant, either express or implied, herein contained, or
     to keep, preserve, or sequester any property and all personal liability of
     every sort, if any, is hereby expressly waived by said Tenant, and by every
     person now or hereafter claiming any right or security hereunder; and that,
     so far as the Trustee is concerned, the owner of any indebtedness or
     liability accruing hereunder shall look solely to the assets of said
     property and the proceeds thereof for the payment thereof.

                     REGISTRATION AND COMMISSION AGREEMENT


April 21, 1987


Mr. Richard Ross, Jr.
Vice President
Scribcor, Inc.
120 W. Madison St.
Suite 1200
Chicago, IL 60602


Dear Dick:

The following is our Registration and Commission Agreement with regard to the
Madison Plaza Three Building, Chicago, Illinois.

If your prospective tenant, The Northern Trust Co., registered by Scribcor, Inc.
consummates a lease for space in the Madison Plaza Three Building, through your
efforts, Madison Plaza Corporation will pay or cause the owner to pay a
brokerage commission at a rate of seven percent (7%) of the first year's rent
and two percent (2%) of the aggregate rent for the remainder of the lease term.
For purposes of this Agreement, the first year's rent shall be deemed to be the
average annual base rent payable over the entire term of the lease after
deductions of rent abatement if any, and any further concessions granted to the
tenant, and without regard to rental adjustment or rental escalation payments
for increases in operating expenses or real estate taxes.

One half of the commission shall be payable within 30 days from execution of the
lease document and start of building construction and the remainder payable 30
days after occupancy by the tenant.

This Agreement will be null and void and of no further force or effect in the
event any of the following does not occur:

     1.  The prospect is brought to the property or sales office for a personal
         inspection by the registrant in the presence of the building leasing
         agent.

     2.  That active and meaningful negotiations take place culminating in the
         consummation of the lease.

<PAGE>
 
April 21, 1987
Page Two

     3.  That the registrant is the procurring cause for said lease.

     4.  That the prospect agrees to recognize the registrant by indemnifying 
         Madison Plaza Corporation and the owner against any future commission,
         claims or litigation as a result of the lease transaction.

     5.  Notwithstanding the above, if another licensed broker or duly 
         authorized individual is properly designated by the prospect to
         represent them, and said party claims or is entitled to a commission,
         Madison Plaza Corporation will recognize only that licensed broker or
         duly authorized individual having a letter or authorization signed by
         the prospect.

If for any reason that tenant fails to occupy the premises, you agree to return
all commission monies paid at the time of lease execution.

No commission will be paid on options for additional space, unless said space is
taken prior to initial occupancy by the tenant, nor will commissions be paid on
lease renewals.

No commission will be paid on charges factored into the rent, i.e. electricity,
periods of free rent, or any above building standard allowances or concessions
amortized over the term of the lease to accommodate the tenant.

Commissions will only be paid for the initial term of the lease, and in no event
for a period longer than fifteen (15) years. In the event the tenant has an
option to terminate the lease, commissions will only be paid to the termination
date.

The commission which will become due and payable under this agreement covers
space to be leased by Northern Trust in addition to the space provided for in
the lease agreement dated August 21, 1985.

Your further act in submitting your prospect will acknowledge your acceptance of
our commission policy.

Sincerely

MIGLIN-BEITLER DEVELOPMENTS

          2.  The last three lines of Paragraph 6 of the Lease are hereby 
deleted, and the following inserted in lieu thereof:

     "and, provided further, Tenant has delivered to Landlord certificates
     evidencing insurance (which insurance shall in all respects and at all
     times comply with the provisions of Paragraph 17C hereof) against any
     liability of Landlord arising from serving of alcoholic beverages in the
     Premises."

          3.  Paragraph 21 of the Lease is hereby deleted, and the following 
inserted in lieu thereof:

     "21. Subordination. This Lease shall be prior to any mortgage or ground or
     underlying lease, provided, however, Tenant agrees to subordinate its
     rights hereunder at all times to (i) the lien of any mortgage or mortgages
     designated by Landlord and all advances made or thereafter made upon the
     security thereof, and (ii) to all future ground or underlying leases of the
     Land and the Building designated by the Landlord and to execute any such
     agreements evidencing such subordination as may be required by the
     mortgagee or ground or underlying lessor, as the case may be, and to attorn
     to and to recognize, as Landlord, the purchaser at a foreclosure sale or
     the mortgagee or its nominee in the event the mortgagee or such nominee
     accepts a deed in lieu of foreclosure, or the ground or underlying lessor
     in the event of termination of such underlying or ground lease in return
     for and upon delivery to Tenant by such purchaser or such mortgagee or its
     nominee or the ground or underlying lessor, as the case may be, of an
     agreement providing that in the event of a foreclosure of such mortgage or
     the giving of the deed in lieu of foreclosure or a termination of such
     ground or underlying lease, this Lease shall not be terminated and Tenant
     may remain in possession of the Premises pursuant to the terms of this
     Lease and retain all the rights, options and privileges granted to it
     hereunder as long as Tenant is not in default hereunder and continues to
     perform its obligations hereunder and further providing that the purchaser
     at a foreclosure sale or transferee in the case of a deed given in lieu of
     foreclosure or ground or underlying lessor, as the case may be, will assume
     all of the obligations of the Landlord in such case; provided, however,
     that in no event shall the mortgagee, said purchaser at a foreclosure sale,
     said transferee in the case of a deed given in lieu of foreclosure or
     ground or

                                      -2-
<PAGE>
 
     underlying lessor, as the case may be, have any personal liability
     whatsoever hereunder for its own acts or omissions or obligations; and
     further provided that the mortgagee, said purchaser at a foreclosure sale
     or said transferee in the case of a deed given in lieu of foreclosure or
     ground or underlying lessor, as the case may be, shall also have no
     personal liability for the acts or omissions or obligations of Landlord
     arising or to be performed prior to any such sale or transfer of the Land
     or Building to such party including, without limitation, any liability for
     any deposits made by the Tenant hereunder, unless such deposits have been
     transferred to such party; and provided, further, that the mortgagee, said
     purchaser at a foreclosure sale, said transferee in the case of a deed
     given in lieu of foreclosure or ground or underlying lessor, as the case
     may be, shall be subject to any offsets or defenses which Tenant might have
     against any prior Landlord pursuant to Tenant's rights as set forth in
     Paragraph 35 hereof. Such agreement may, among other things, require the
     Tenant to notify the mortgagee or the ground or underlying lessor of any
     default by the Landlord and afford such a mortgagee a reasonable
     opportunity to cure such default prior to any termination of this Lease by
     Tenant provided that the Premises are reasonably usable by Tenant for its
     normal business activities. Tenant further agrees that, except as to
     secondary mortgage financing expressly permitted in such mortgage or ground
     or underlying lease, it will not, without the consent of the mortgagee or
     ground or underlying lessor, as the case may be, voluntarily subordinate
     this Lease to any lien or encumbrance without the consent of said mortgagee
     or ground or underlying lessor, as the case may be. To fulfill Tenant's
     obligations under the provisions of this Paragraph 21, Tenant agrees that
     it will execute a Subordination, Non-Disturbance and Attornment Agreement
     in the form attached to this Lease as Exhibit G."

          4. The second full paragraph of Paragraph 25 of the Lease is hereby 
deleted, and the following inserted in lieu thereof:

     "The term "Landlord" as used in this Lease means only the owner or the
     mortgagee in possession (including anyone claiming any title or any
     interest in the Land or the Building by, through or under said mortgagee)
     for the time being of the Land and the Building (or the owner of a lease of

                                      -3-
<PAGE>
 
     the Building or of the Land and the Building) of which the Premises form a
     part, so that in the event of any sale or sales (including a sale or
     transfer arising by virtue of a foreclosure of any mortgage of the Land or
     the Building or any deed given in lieu of foreclosure thereof) of the Land
     and the Building or of said lease, or in the event of a lease of the
     Building, or the Land and the Building, except for the obligations set
     forth in Paragraph 36, Landlord shall be and hereby is entirely free and
     relieved of all covenants and obligations of Landlord thereafter to be
     performed hereunder, provided any purchaser, transferee or lessee of the
     Building, or of the Building and the Land has, subject to the provisions of
     Paragraph 21 hereof, assumed and agreed to carry out any and all covenants
     and obligations of Landlord hereunder thereafter to be performed."

          5.  The following sentence is hereby added at the end of and as a part
of Paragraph 36B of the Lease:

     "Notwithstanding the foregoing provisions of this paragraph, Tenant shall
     have no right to terminate this Lease as aforesaid provided in the event
     Landlord's interest in the Land or Building or this Lease, or all of the
     aforesaid, is transferred and Landlord or its affiliate does not remain the
     developer and manager of the Building, all as a result of a mortgage
     foreclosure sale of any mortgage of the Land or the Building or a deed
     given in lieu of foreclosure thereof during the period commencing on the
     date of execution of this Lease and expiring one (1) year after the
     Commencement Date of this Lease."

          6.  The following sentence is inserted at the end of and as part of 
Paragraph 43C of the Lease:

     "Further, the rights of Tenant and restrictions set forth in this Paragraph
     43 shall also not apply to any sale or transfer of the Land or Building
     pursuant to a mortgage foreclosure sale of any mortgage of the Land or
     Building or any deed given in lieu of foreclosure thereof but shall
     thereafter apply to any transfer by the purchaser who took title at said
     mortgage foreclosure sale including the holder of said mortgage or its
     nominee who took title by virtue of said mortgage foreclosure sale or deed
     in lieu of foreclosure thereof."

                                      -4-

          7. As amended herein, the Lease shall remain in full force and effect
 and, except as expressly amended herein, shall be unaffected hereby. In the
 event of any conflict between the provisions of this Amendment and the
 provisions of the Lease, the provisions of this Amendment shall control.

           8. This Third Amendment to Agreement of Lease is executed by American
National Bank and Trust Company, not personally, but in the exercise of the
power and authority conferred upon and vested in it as Trustee. It is expressly
understood and agreed that nothing herein shall be construed as creating any
liability whatsoever against Trustee personally; and in particular, without
limiting the generality of the foregoing, there shall be no personal liability
to pay any indebtedness accruing hereunder or to perform any covenant, either
express or implied, herein contained, or to keep, preserve, or sequester any
property and all personal liability of every sort, if any, is hereby expressly
waived by said Tenant, and by every person now or hereafter claiming any right
or security hereunder; and that, so far as the Trustee is concerned, the owner
of any indebtedness or liability accruing hereunder shall look solely to the
assets of said property and the proceeds thereof for the payment thereof.

                                   EXHIBIT G
            SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT

     THIS AGREEMENT, made this      day of         , 19 between The Northern
Trust Company, an Illinois banking corporation with offices at
(hereinafter called "Tenant"), CIGNA Investments, Inc., a Connecticut 
corporation having its principal office and place of business at 900 Cottage
Grove Road, Bloomfield, Connecticut or its nominee (hereinafter called
"Lender"), and American National Bank and Trust Company of Chicago, not
personally, but as Trustee under Trust Agreement dated August 21, 1985 and known
as Trust No. 65287 (hereinafter referred to as "Landlord").


                                  WITNESSETH:
                                  ----------

     WHEREAS, the Tenant has entered into a certain lease (the "Lease") dated   
              , with Landlord covering premises within a certain building known 
as                   (the "Premises"); and more particularly described in 
Exhibit "A" attached hereto and incorporated herein; and

     WHEREAS, the Lender has agreed to make a loan secured by a mortgaged (the 
"Mortgage") to the Landlord, (is currently the holder of a mortgage covering the
Premises pursuant to a Mortgage Deed dated               , and recorded 
        in Mortgage Book           , Page    in              (the "Mortgage") 
securing a loan to the Landlord); and

     WHEREAS, it is to the mutual benefit of the parties hereto that Lender make
such loan to Landlord; and

     WHEREAS, it is a condition precedent to obtaining said loan or was a 
condition of said loan, that said Mortgage securing said loan be a lien or 
charge upon the Premises unconditionally prior and superior to the Lease and 
leasehold interest of Tenant; and

     WHEREAS, Tenant acknowledges when it is recorded that said Mortgage 
constitutes, or will constitute, a lien or charge upon the Premises which is, or
should be, unconditionally prior and superior to the Lease and leasehold 
interest of Tenant; and

<PAGE>
 
     WHEREAS, Lender has been requested by Tenant and by Landlord to enter into 
a non-disturbance agreement with Tenant;

     NOW, THEREFORE, in consideration of the premises and mutual covenants 
hereinafter contained, the parties hereto mutually covenant and agree as 
follows:

     1. The Lease and any extensions, renewals, replacements or modifications 
thereof, and all of the right, title and interest of the Tenant in and to said
Premises are and shall be subject and subordinate to the Mortgage and to all of
the terms and conditions contained herein, and to any renewals, modifications,
replacements, consolidations and extensions thereof; and, pursuant to Paragraph
43C of the Lease, Lender may exercise its right to purchase the Premises
pursuant to the Mortgage before Tenant may exercise its right to purchase the
Premises pursuant to Paragraph 43 of the Lease. In the event that Lender shall
not elect to exercise its prior right to purchase the Premises pursuant to the
Mortgage, and Tenant thereafter does elect to purchase the Premises pursuant to
Paragraph 43 of the Lease, then such exercise by Tenant of its right to purchase
the Premises pursuant to Paragraph 43 of the Lease shall in all events be
subject and subordinate to the terms and conditions of the Mortgage. Tenant
agrees that Tenant's right to purchase the Premises set forth in Paragraph 43 of
the Lease shall not apply to any transfer of the Premises pursuant to a mortgage
foreclosure sale or deed given in lieu of foreclosure thereof. Lender agrees
that Tenant's right to purchase the Premises as set forth in Paragraph 43 of the
Lease shall apply to (a) any subsequent transfer by Lender of the Premises in
the event Lender has acquired title to the Premises pursuant to Lender's right
to purchase the Premises as set forth in the Mortgage (and in the event Tenant
does so then exercise its right to purchase the Premises, such exercise shall in
all events be subject and subordinate to the Mortgage if said Mortgage is then
in effect); and (b) any subsequent transfer by the purchaser who took title to
the Premises at said mortgage foreclosure sale including the holder of the
Mortgage or its nominee who took title by virtue of said mortgage foreclosure
sale or deed in lieu of foreclosure thereof (and in the event Tenant does so
then exercise its right to purchase the Premises, such exercise shall in all
events be subject and subordinate to the Mortgage if said Mortgage is then in
effect).

     2. Lender consents to the Lease and, in the event of foreclosure of said 
Mortgage, or in the event Lender comes into possession or acquires title to the 
Premises as a result of the enforcement of foreclosure of the Mortgage or the 
note secured thereby, or as a result of any other means, Lender agrees to 
recognize Tenant and

                                      -2-

<PAGE>
 
further agrees that it will not terminate the Lease nor disturb Tenant's 
possession of the Premises so long as Tenant is not in default under any of the 
terms, covenants or conditions of the Lease.

     3. Tenant agrees with Lender that if the interests of Landlord in the 
Premises shall be transferred to and owned by Lender by reason of foreclosure or
other proceedings brought by it, or any other manner, or shall be conveyed 
thereafter by Lender or shall be conveyed pursuant to a foreclosure sale of the 
Premises (and for purposes of this paragraph, the term "Lender" shall be deemed
to include any grantee of the lender or purchaser at foreclosure sale), Tenant 
shall be bound to Lender under all of the terms, covenants and conditions of the
Lease for the balance of the term thereof remaining and any extensions or 
renewals thereof which may be effected in accordance with any option therefor in
the Lease, with the same force and effect as if Lender were the Landlord under 
the Lease, and Tenant does hereby attorn to Lender as its Landlord, said 
attornment to be effective and self-operative without the execution of any 
further instruments on the part of any of the parties hereto immediately upon 
Lender succeeding to the interest of the landlord in the Premises. Tenant 
agrees, however, upon the election of and written demand by Lender within twenty
(20) days after Lender receives title to the Premises, to execute an instrument 
reasonably satisfactory in form and substance to Tenant, in confirmation of the 
foregoing provisions, in which Tenant shall acknowledge such attornment and 
shall set forth the terms and conditions of its tenancy.

     4. Tenant and Lender agree that if Lender shall succeed to the interest of 
Landlord under the Lease, Lender shall assume all of the obligations of the 
Landlord under the Lease which arise and are to be performed by the landlord 
prior to and during the period Lender is the Landlord under the Lease; provided,
however, that in no event shall the Lender (a) have any personal liability 
whatsoever under the Lease for the performance of the Landlord's obligations 
thereunder (whether such performance or failure of performance shall be that of 
Lender or any prior Landlord), or (b) bound by an security deposit which Tenant 
may have paid to any prior landlord, unless such deposit is in an escrow fund 
available to Lender, or (c) be bound by any amendment or modification of the 
Lease made without Lender's consent. Tenant further agrees with Lender that 
except as to secondary mortgage financing expressly permitted in the Mortgage, 
Tenant will not voluntarily subordinate the Lease to any lien or encumbrance 
without Lender's consent, and in no event shall Tenant voluntarily subordinate 
the Lease to any lien or encumbrance unless Lender shall have first approved the
form and substance of the instrument by which such

                                      -3-

<PAGE>
 
subordination is accomplished, which approval Lender agrees not to withhold 
unreasonably.

     5. In the event that the landlord shall default in the performance or 
observance of any of the terms, conditions or agreements in the Lease, Tenant 
shall give written notice thereof to the Lender and the Lender shall have the 
right (but not the obligation) to cure such default. Tenant shall not take any 
action with respect to such default under the Lease including without limitation
any action in order to terminate, rescind or void the Lease (provided the 
Premises are reasonably usable by Tenant for its normal business activities) or 
to withhold any rental thereunder, for a period of 10 days after receipt of such
written notice thereof by the Lender with respect to any such default capable of
being cured by the payment of money and for a period of 30 days after receipt of
such written notice thereof by the Lender with respect to any other such default
(provided, that in the case of any default which cannot be cured by the payment 
of money and cannot with diligence be cured within such 30-day period because of
the nature of such default or because Lender requires time to obtain possession 
of the Premises in order to cure the default, if the Lender shall proceed 
promptly to attempt to obtain possession of the Premises, where possession is 
required, and to cure the same and thereafter shall prosecute the curing of 
such default with diligence and continuity, then the time within which such 
default may be cured shall be extended for such period as may be necessary to 
complete the curing of the same with diligence and continuity).

     6. This Agreement shall bind and inure to the benefit of the parties 
hereto, their successors and assigns. As used herein the term "Tenant" shall 
include the Tenant, its successors and assigns; the words "foreclosure" and 
"foreclosure sale" as used herein shall be deemed to include the acquisition of 
Landlord's estate in the Premises by voluntary deed (or assignment) in lieu of 
foreclosure, and the word "Lender" shall include the Lender herein specifically 
named and any of its successors and assigns, including anyone who shall have 
succeeded to Landlord's interest in the Premises by, through or under 
foreclosure of the Mortgage.

     7. This Agreement shall be the whole and only agreement between the parties
hereto with regard to the subordination of the Lease and leasehold interest of 
Tenant to the lien or charge of the Mortgage in favor of Lender, and shall 
supersede and cancel any prior agreements as to such, or any, subordination, 
including, but not limited to, those provisions, if any, contained in the Lease,
which provide for the subordination of the Lease and leasehold interest of 
Tenant to a deed or deeds of trust or to a mortgage or mortgages to be 
thereafter executed, and shall

                                      -4-

<PAGE>
 
not be modified or amended except in writing signed by all parties hereto.

     8. The use of the neuter gender in this Agreement shall be deemed to 
include any other gender, and words in the singular number shall be held to 
include the plural, when the sense requires.

     IN WITNESS WHEREOF, the parties hereto have placed their hands and seals 
the day and year first above written.

                    FOURTH AMENDMENT TO AGREEMENT OF LEASE
                    --------------------------------------

     THIS FOURTH AMENDMENT TO AGREEMENT OF LEASE (this "Amendment"), made and 
entered into as of May 1, 1990 by and between American National Bank and Trust 
Company of Chicago, as Trustee under Trust Agreement dated April 5, 1990 and 
known as Trust 110513-07 ("Landlord") and The Northern Trust Company, an 
Illinois banking corporation ("Tenant"),

                               WITNESSETH: THAT

     WHEREAS, American National Bank and Trust Company of Chicago Trust No. 
65287 and Tenant are parties to a certain Agreement of Lease dated as of August 
27, 1985; and

     WHEREAS, the Agreement of Lease was amended by (i) that certain First 
Amendment to Agreement of Lease dated as of August 15, 1986, (ii) that certain 
Second Amendment to Agreement of Lease dated as of August 6, 1987, and (iii) 
that certain Third Amendment to Agreement of Lease dated as of May 20, 1988 (as 
so amended, the "Lease"); and

     WHEREAS, the Lease was assigned by American National Bank and Trust Company
of Chicago Trust No. 65287 to Landlord by Assignment dated April 6, 1990; and

     WHEREAS, Landlord and Tenant desire to further amend the Lease as 
hereinafter set forth;

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

     1. Paragraph 1A of the Lease is hereby deleted, and the following inserted 
in lieu thereof:

     "A. The Premises shall be all of the 5th through 14th floors of the
     Building and a portion of each of the 15th and 16th floors of the Building,
     and shall in the aggregate contain approximately 215,952 RSF (as defined in
     Paragraph 1D hereof). The portion of the Premises located on floors 5
     through 9 of the Building, containing in the aggregate approximately
     100,000 RSF, is sometimes referred to herein as the "Original Premises".
     The portion of the Premises located on floors 10 through 15 of the
     Building, containing in the aggregate approximately 100,000 RSF, is
     sometimes referred to herein as the "Additional Premises". The portion of
     the Premises located on the 16th floor of the Building, containing
     approximately 15,952 RSF, is sometimes referred to herein as the "16th
     Floor Premises". The "Original Premises", the "Additional Premises" and the



<PAGE>
 
     "16th Floor Premises" shall, in the aggregate, comprise the Premises."

     2. The following is hereby inserted into the Lease as Paragraph 2BB, 
immediately following Paragraph 2B and preceding Paragraph 2C:

     "BB. 16th Floor Additional Work.

          Landlord will perform, at Tenant's request, and upon submission by 
Tenant of the necessary plans and specifications in accordance with the terms 
hereof, any additional work in the 16th Floor Premises over and above that 
specified in Paragraph 2A above, subject to the terms and conditions of this 
Paragraph 2BB. If included in Tenant's plans and specifications, Landlord will
supply and install the Building Standard Work in the Premises in Landlord's 
standard manner; provided, however, that regardless of whether Tenant elects to 
have Landlord supply and install the Building Standard Work, all materials 
specified for use in the additional work requested by Tenant for the 16th Floor 
Premises shall be of quality at least equal to the materials specified by 
Landlord for the Building Standard Work. All work done pursuant to this 
Paragraph 2BB shall be at Landlord's cost to the extent of the sum of Thirty-one
and 35/100 ($31.35) Dollars per RSF for the 16th Floor Premises (hereinafter 
referred to as the "16th Floor Allowance"), and at Tenant's sole cost and 
expense to the extent the cost of such work exceeds the 16th Floor Allowance; 
the aggregate investment tax credit, if any, attributable to all such work shall
be divided between Landlord and Tenant in the proportion which each bears to the
cost of all such work. All such cost calculations shall be based on the RSF 
actually included in the 16th Floor Premises on the 16th Floor Premises 
Commencement Date (as hereinafter defined). Any portion of the 16th Floor 
Allowance not applied to defray the cost of such additional work shall, at 
Tenant's option, either (i) be applied in payment of the first Rent payable 
hereunder, or (ii) be paid to Tenant in cash on the 16th Floor Premises 
Commencement Date (as defined in Paragraph 3A hereof.)

     3. The following is hereby inserted into the Lease as Paragraph 3I:

                                      -2-
<PAGE>


          "I.  Notwithstanding the foregoing provisions of this Paragraph 3, the
     "Commencement Date" with respect to the 16th Floor Premises (sometimes
     referred to herein as the "16th Floor Premises Commencement Date") shall be
     the later of (i) August 1, 1990 or (ii) the date the work to be performed
     by Landlord for the 16th Floor Premises pursuant to Paragraph 2BB is
     substantially complete (excluding any delay in substantial completion 
     caused by Tenant Delay). Tenant's obligations to pay Rent and Operating
     Expenses allocable to the 16th Floor Premises shall commence as of the 16th
     Floor Premises Commencement Date. In the event that the 16th Floor Premises
     shall be ready for occupancy by Tenant prior to the 16th Floor Premises
     Commencement Date, Tenant shall be entitled to occupy the 16th Floor
     Premises until the 16th Floor Premises Commencement Date without payment of
     Base Rent or Operating Expenses allocable thereto.

     4.  Paragraph 4A of the Lease is hereby deleted, and the following inserted
in lieu thereof:

     "A.  "Base Rent"

          (i)  "Original Base Rent".  For the Original Premises, the sum equal 
     to the number of RSF within the Original Premises times $21.00 per RSF for
     each twelve month period during the Term of this Lease ("Original Annual
     Base Rent"). Such Original Annual Base Rent shall be paid in monthly
     installments of one-twelfth (1/12) of the then-current Original Annual Base
     Rent in advance on or before the first day of each and every month during
     the Term ("Original Monthly Base Rent"), as the Original Annual Base Rent
     or Original Monthly Base Rent may be adjusted pursuant to Paragraph 5 of
     this Lease.

          (ii)  "Additional Base Rent".  For the Additional Premises, the sum
     equal to the number of RSF within the Additional Premises times (A) $18.50
     per RSF for the first (1st) through the fifth (5th) Lease Years (as defined
     in Section 5A) during the Term, (B) $22.50 per RSF for the sixth (6th)
     through tenth (10th) Lease Years during the Term, and (C) $25.50 per RSF
     for the eleventh (11th) through fifteenth (15th) Lease Years during the
     Term ("Additional Annual Base Rent"). Such Additional Annual Base Rent
     shall be paid in monthly installments of one-twelfth (1/12) of the then
     current Additional Annual Base Rent in advance on or before the first day 
     of each and every month during the Term ("Additional  
          
                                      -3-
<PAGE>
 

     Monthly Base Rent"), as the Additional Annual Base Rent or Additional
     Monthly Base Rent may be adjusted pursuant to Paragraph 5 of this Lease;

          (iii)  "16th Floor Base Rent".  For the 16th Floor Premises, annual
     Base Rent ("16th Floor Annual Base Rent") shall be payable at the rate
     of (A) $29.00 per RSF for the first sixty-six (66) months following the
     16th Floor Premises Commencement Date, and (B) $29.89 per RSF for the
     remainder of the initial Term. Such additional 16th Floor Annual Base Rent
     shall be paid in monthly installments of one-twelfth (1/12) of the then
     current 16th Floor Annual Base Rent in advance on or before the first day
     of each and every month during the Term ("16th Floor Monthly Base Rent"),
     as the 16th Floor Annual Base Rent or 16th Floor Monthly Base Rent may be
     adjusted pursuant to Paragraph 5BB of this Lease;

          (iv)  Original Annual Base Rent, Additional Annual Base Rent and 16th
     Floor Annual Base Rent are sometimes collectively referred to herein as
     "Annual Base Rent"; Original Monthly Base Rent, Additional Monthly Base
     Rent and 16th Floor Monthly Base Rent are sometimes collectively referred
     to herein as "Monthly Base Rent"."

     5.  Paragraph 5A(iv) of the Lease is hereby amended by deleting the phrase

     "prior to the end of the third full Lease Year means the sum of $9.00 per
     rentable square foot of the Building per annum and thereafter"

which appears in the first through the third lines of Paragraph 5A(iv).

     6.  Paragraph 5B of the Lease is hereby deleted and the following inserted
in lieu thereof:

     "B.  Rent Adjustments.  The Annual Base Rent (excluding the 16th Floor
     Annual Base Rent) for each and every Lease Year during the term of this
     Lease (the "Subject Lease Year") shall be adjusted (subject to the 
     limitations hereinafter set forth) by an amount equal to the following
     (the "Rent Adjustment"):

          (i)  For the Base Year (and first full Lease Year if the Base Year
     commences subsequent to July 1 of such year), an amount equal to the
     lesser of (a) the product    

                                      -4-
<PAGE>
 

     of thirty percent (30%) of the Base Rent (excluding the 16th Floor Annual
     Base Rent) paid during the Base Year multiplied by the percentage change
     (positive or negative) of the CPI for the month in which the Term of this
     lease commences over the CPI for the month in which this Lease was
     executed, and (b) $1.00 per RSF; and

          (ii)  For each Lease Year thereafter, an amount equal to the product
     of thirty percent (30%) of the Annual Base Rent (excluding the 16th Floor
     Annual Base Rent) plus the sum determined by subparagraph B(i) above
     multiplied by the percentage change (positive or negative) of the CPI for
     January of the Subject Lease Year over the CPI for the first full month of
     the Base Year; provided, however, that for any Lease Year the amount of the
     annual Rent Adjustment made by reason of change in the CPI shall not exceed
     three percent (3%) of the adjusted Annual Base Rent (excluding the 16th
     Floor Annual Base Rent) for the immediately preceding Lease Year. The
     limitation set forth in the immediately preceding sentence shall not affect
     adjustments to Rent attributable to causes other than changes in the CPI."

     "BB.  16th Floor Rent Adjustments.  The 16th Floor Annual Base Rent shall
     be adjusted by an amount equal to the following (the "16th Floor Rent
     Adjustment"):

     For each Lease Year commencing with the Lease Year beginning January 1,
     1997, an amount equal to the product of $29.89 per RSF, multiplied by 35%
     of the percentage increase (if any) of the CPI for January of the Subject
     Lease Year over the CPI for the 66th month following the 16th Floor 
     Premises Commencement Date."

     7.  Paragraph 5C of the Lease is hereby deleted, and the following inserted
in lieu thereof:

          "C.  Partial Rent Abatement.  Notwithstanding anything in this Lease
     to the contrary, Annual Base Rent and any Rent Adjustment (excluding 16th
     Floor Annual Base Rent and the 16th Floor Rent Adjustment) shall be abated
     by one-half (50%) until the beginning of the forty-ninth (49th) month of
     the Term. 16th Floor Annual Base Rent and the 16th Floor Rent Adjustment
     shall not be abated as provided in this Paragraph 5C."

     8.  The following is hereby inserted at the end of, and as part of,
Paragraph 5D of the Lease:

                                      -5-
<PAGE>
 
     "Notwithstanding the foregoing, Operating Expenses payable hereunder shall 
     be limited as follows:

     (x) Operating Expenses payable with respect to the Original Premises and
     the Additional Premises shall be fixed at $9.00 per RSF per year through
     the end of the third (3rd) full Lease Year (regardless of the actual
     Operating Expenses for such period).

     (y) Operating Expenses payable with respect to the 16th Floor Premises (i)
     shall be abated entirely during the first 12-month period following the
     16th Floor Premises Commencement Date, (ii) shall not exceed $10.50 per RSF
     per annum for the second 12-month period (i.e. the 13th through 24th
     months) following the 16th Floor Premises Commencement Date, and (iii)
     shall not exceed $13.00 per RSF per annum for the third 12-month period
     (i.e. the 25th through 36th months) following the 16th Floor Premises
     Commencement Date.

     9. Paragraph 27 is hereby deleted and the following inserted in lieu
thereof:

     "27. PARKING. Landlord represents to Tenant that the Building will include
     approximately 56 parking spaces located in the Building's underground
     garage. Tenant shall have the right to lease for the full term Tenant's
     Proportionate Share of such parking spaces (which share shall be not less
     than 13 spaces), at regular annual Building rates therefor, and in
     locations designated by Landlord, such right to remain exercisable for 12
     spaces until the Commencement Date, and for one space until the 16th Floor
     Commencement Date, and to include the right to sublease to any sublessee of
     space in the Premises or to employees or partners of such sublessees or of
     Tenant. In addition, Tenant shall be entitled, at regular annual Building
     rates therefor, to any parking spaces which were rented by the immediately
     preceding tenants in space added to the Premises after the Commencement
     Date. Tenant may give up such parking spaces, or any thereof, so leased at
     any time(s) on not less than sixty (60) days' notice and shall not have any
     rights for the number of spaces so given up at any time thereafter.
     Notwithstanding the immediately preceding sentence, Tenant shall have the
     right to sublease any parking spaces leased hereunder to parties
     (including, but not limited to, car rental entities) selected by Tenant,
     provided that (i) the rent charged for any parking spaces

                                      -6-

<PAGE>
 
     so subleased is less than or equal to the rent charged Tenant by Landlord 
therefor, and (ii) the use of the subleased parking spaces by the sublessees 
thereof does not interfere with Landlord's operation of the garage or use of the
garage by other parking lessees."

     10. Paragraphs 30A and 30B of the Lease are hereby deleted and the
following inserted in lieu thereof:

     "A. Landlord hereby grants to Tenant the option to lease the entire fourth
(4th) floor of the Building, the balance of the fifteenth (15th) and sixteenth 
(16th) floors of the Building, and the entire seventeenth (17th) floor of the 
Building (the "6th Year Option Floors"). Tenant may lease any or all of the 
6th Year Option Floors contiguous to the Premises, as designated by Landlord, 
commencing at some point during the 6th Lease Year as determined by Landlord.

      B. Landlord hereby grants to Tenant the further option to lease three (3)
additional floors contiguous to the Premises (subject to the last sentence of
this Paragraph 30B) designated by Landlord ("11th Year Option Floors"), which
Option may be exercised whether or not Tenant has taken any, all or none of the
6th Year Option Floors. Tenant may lease any or all of the 11th Year Option
Floors commencing at some point during the 11th Lease Year as determined by
Landlord.

     11. The following is hereby inserted in the Lease as Paragraph 45:

     "45. ASSUMPTION OF CERTAIN FINANCIAL OBLIGATIONS OF TENANT. In 
consideration of Tenant's Lease of the 16th Floor Premises, Landlord hereby 
agrees to assume (i) from and after April 1, 1990, all of the financial 
obligations and financial liabilities of Tenant, as the tenant, arising after 
April 1, 1990 under the First, Second and  Third Expansion Amendments to that 
certain Lease dated November 27, 1985, demising approximately 13,000 RSF on the 
5th Floor of Madison Plaza, and (ii) from and after September 1, 1990, one-half 
(1/2) of the financial obligations and financial liabilities of The Griffin 
Group (now known as The Northern Investment Management Co.), an affiliate of 
Tenant, as the tenant, arising after September 1, 1990 under that certain Lease 
dated May 1, 1984 (as amended by the Expansion Amendment thereto) demising 
approximately 10,300 RSF on the 27th


                                      -7-

<PAGE>
 
     floor of Madison Plaza (collectively the "200 Madison Leases"). The
     aforesaid assumption by Landlord relates only to the financial obligations
     and financial liabilities of Tenant as the tenant under the 200 Madison
     Leases; nothing herein shall be deemed or construed to be an assumption by
     Landlord of any other obligations of Tenant under the 200 Madison Leases,
     and in no event shall Landlord be obligated to perform any act or do any
     thing other than the payment of money required of Tenant as the tenant
     under the 200 Madison Leases. Tenant warrants and represents to Landlord
     that it has delivered to Landlord true and correct copies of the 200
     Madison Leases, and there are no additional agreements between the landlord
     thereunder and Tenant, whether written or oral, pertaining to the 200
     Madison Leases, or the subject matter or terms thereof. Tenant covenants
     and agrees (i) to permit Landlord to assign, or to sublease all or any
     portion of the premises demised by, the 200 Madison Leases, upon such terms
     and conditions as are acceptable to Landlord in its sole and uncontrolled
     discretion, and (ii) to cooperate in all respects with Landlord in
     Landlord's efforts to assign, or sublease the premises demised by, the 200
     Madison Leases, including without limitation the execution of any required
     documents of assignment or sublease (provided such documents are in form
     reasonably acceptable to Tenant.) All rent or other consideration received
     for or on account of the 200 Madison Leases or the premises demised thereby
     from and after April 1, 1990 shall be the sole property of Landlord
     (regardless of whether such amounts exceed the financial obligations
     assumed by Landlord with respect to the 200 Madison Leases), and Tenant
     shall in no event be entitled to share therein.


     12.  As amended herein, the Lease shall remain in full force and effect
and, except as expressly amended herein, shall be unaffected hereby. In the
event of any conflict between the provisions of this Amendment and the
provisions of the Lease, the provisions of this Amendment shall control.


     13.  This Fourth Amendment to Agreement of Lease is executed by American
National Bank and Trust Company, not personally, but in the exercise of the
power and authority conferred upon and vested in it as Trustee. It is expressly
understood and agreed that nothing herein shall be construed as creating any
liability whatsoever against Trustee personally; and in particular, without
limiting the generality of the foregoing, there shall be no personal liability
to pay any indebtedness accruing hereunder or


                                      -8-

<PAGE>
 

to perform any covenant, either express or implied, herein contained, or to
keep, preserve, or sequester any property and all personal liability of every
sort, if any, is hereby expressly waived by said Tenant, and by every person now
or hereafter claiming any right or security hereunder; and that, so far as the
Trustee is concerned, the owner of any indebtedness or liability accruing
hereunder shall look solely to the assets of said property and the proceeds
thereof for the payment thereof.

     IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
executed as of the day and year first above written.

TRUST COMPANY OF CHICAGO, not individually, but solely and only as Trustee under
a certain Trust Agreement dated the 5th day of April, 1990 and known as Trust

                               WITNESSETH: THAT
                               ----------------

      WHEREAS, American National Bank and Trust Company of Chicago Trust No. 
65287 and Tenant are parties to a certain Agreement of Lease dated as of August

      WHEREAS, the Lease was assigned by American National Bank and Trust 
Company of Chicago Trust No. 65287 to Landlord by Assignment dated April 6, 
1990; and 

      WHEREAS, Landlord and Tenant desire to further amend the Lease as 
hereinafter set forth;

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

      1.   Paragraph 1A of the Lease is hereby deleted, and the following 
inserted in lieu thereof:

      "A. The Premises shall be all of the 4th through 14th floors of the
      Building and a portion of each of the 15th and 16th floors of the
      Building, and shall in the aggregate contain approximately 232,443 RSF (as
      defined in Paragraph 1D hereof). The portion of the Premises located on
      floors 5 through 9 of the Building, containing in the aggregate
      approximately 102,110 RSF, is sometimes referred to herein as the
      "ORIGINAL PREMISES". The portion of the Premises located on floors 10
      through 15 of the Building, containing in the aggregate approximately
      97,890 RSF, is sometimes referred to herein as the "ADDITIONAL PREMISES".
      The portion of the Premises located on the 16th floor of the Building,
      containing approximately 15,952 RSF, is sometimes referred to herein as
      the "16TH FLOOR PREMISES". The portion of the Premises located on the 4th
      Floor of the Building containing approximately 16,491 RSF, is sometimes
      referred to herein as the "4TH FLOOR PREMISES". The "Original Premises",
      the

<PAGE>
 
     "Additional Premises" and the "16th Floor Premises" and the 4th Floor 
     Premises shall, in the aggregate, comprise the Premises."

     2.  The following is hereby inserted into the Lease as subsection 2.01, 
immediately following Paragraph 2H and preceding Section 3:

     "2.01  Construction of the 4th Floor Premises.

          A.  Tenant's Plans.  The Tenant shall, at Tenant's sole cost and 
     expense (subject to the credit hereinafter granted), cause to be prepared
     and submitted to the Landlord at such time as Tenant desires plans and
     specifications (the "Tenant's Plans"), including, but not limited to, all
     space plans, working drawings, mechanical and engineering drawings for
     Landlord's prior approval, disclosing all construction to be performed to
     build out the entire 4th Floor Premises. The Landlord agrees to review and
     either approve or disapprove (and noting with such disapproval the specific
     items not approved) Tenant's Plans within ten (10) business days of
     Landlord's receipt of a complete set of Tenant's Plans. In the event
     Tenant's Plans are disapproved, Tenant shall revise and resubmit Tenant's
     Plans expeditiously and Landlord shall review the same and notify the
     Tenant of its approval or disapproval within five (5) business days
     thereafter in the same manner as required for the initial submittal.
     Landlord's approval shall not be unreasonably withheld or delayed.

          B.  General Contractor.  The Tenant is hereby granted the right to 
     utilize contractors of Tenant's own choice to build out the 4th Floor
     Premises, subject to Landlord's reasonable approval as to the
     qualifications of such contractor. Only qualified contractors shall be
     permitted to bid on the Work. The contractor chosen by the Tenant as the
     successful bidder is hereinafter referred to as "Tenant's Contractor". The
     Tenant, before commencing any work on or to the 4th Floor Premises, shall
     submit Tenant's Plans and written contracts for such work by Tenant's
     Contractor to Landlord for approval. The Landlord may impose such
     reasonable conditions as Landlord, in its reasonable judgment, deems
     appropriate, including, without limitation, conditions which will assure
     Landlord that all work will be performed lien-free (including performance
     and payment bonds) and with proper insurance coverage. All installations,
     alterations and additions shall be constructed in a good and workmanlike
     manner and only new and good grades of material shall be used. Such work
     performed by Tenant's Contractor shall comply with all insurance
     requirements and all other ordinances and regulations of the City of
     Chicago or any department or agency thereof and with the requirements of
     all statutes and regulations of the State of Illinois or any department or
     agency thereof. Tenant shall permit Landlord (or an architect designated by
     Landlord) to supervise all construction operations within the 4th Floor
     Premises performed by Tenant's Contractor. Tenant shall pay to the Landlord
     the cost of any materials purchased from Landlord at Landlord's actual
     invoice cost for said items, the reasonable and actual cost incurred by
     Landlord in supervising the construction (which shall not exceed an amount
     equal to one and one-half (1 1/2%) percent of the cost of construction)

                                       2


<PAGE>
 
          and all hoisting charges (the "Reimbursables"). Such supervision by
          the Landlord of the Tenant's Contractor shall be solely and only for
          the benefit of the Landlord. No silence or statement by the Landlord's
          supervisor shall be deemed or construed as an assumption by said
          supervisor or Landlord of any responsibility for or in relation to the
          construction of the 4th Floor Premises or any guarantee that the work
          completed within the 4th Floor Premises complies with Laws, complies
          with Tenant's Plans, or is suitable or acceptable to the Tenant for
          Tenant's intended business purposes. If the Tenant elects to build out
          the 4th Floor Premises with Tenant's Contractor, Tenant shall furnish
          to Landlord prior to commencement thereof building permits and
          certificates of appropriate insurance and bonds and upon completion of
          any installations, alterations or additions, contractor's affidavits
          and full and final waivers of lien covering all labor and material
          expended and used in constructing the 4th Floor Premises. Tenant shall
          hold Landlord harmless and indemnify Landlord from all claims and
          costs, damages, liens and expenses which may arise out of or are
          connected in any way with said construction by Tenant's Contractor.

               C. Construction Credit. The cost of all work (the "Work")
          necessary to build out all of the 4th Floor Premises (including, but
          not limited to, all labor, material, permits and working drawings,
          design costs and Reimbursables) shall, subject to the credit granted
          herein, be the responsibility of Tenant. The Landlord does hereby
          grant to the Tenant a credit (the "Construction Credit") equal to
          Eight Hundred Forty-Two Thousand Seven Hundred Twenty-Five and 56/100
          ($842,725.56) Dollars. The Construction Credit shall be paid in
          installments by Landlord to the Tenant as the Work progresses within
          thirty (30) days of Tenant's request indicating the dollar amount of
          the draw Tenant desires; provided that the Tenant, together with such
          request, presents to Landlord, reasonable documentation evidencing (i)
          the amounts of payments previously made by Tenant, in relation to the
          Work, to the general contractor and any subcontractors and
          materialmen, including, but not limited to, general contractor's
          statement and partial and final lien waivers, as the case may be,
          covering all Work (including design costs and Reimbursables) for which
          Tenant is requesting payment; and (ii) the percentage of the Work
          completed. Tenant shall be responsible for obtaining and submitting to
          Landlord all documentation reasonably required by the Landlord in
          relation to Construction Credit draw requests made by Tenant.
          Construction Credit draw amounts shall never exceed, in the aggregate,
          the lesser of: (i) the remaining unpaid amount of the Construction
          Credit, minus any then unpaid Reimbursables, or (ii) that amount equal
          to the cost of all Work completed in accordance with the Tenant's
          Plans and paid for by Tenant, as evidenced by the documentation
          furnished with such request (including lien waivers). Any unused
          portion of the Construction Credit shall be credited by the Landlord
          against Monthly Base Rent next due under the Lease, until exhausted.

               Notwithstanding anything to the contrary expressed in, or implied
          by this Fifth Amendment to Agreement of Lease, Tenant, at its sole
          election, may choose not to build out the 4th Floor Premises for and
          as office space but instead, may choose to utilize the 4th Floor
          Premises as office storage space and consequently, the work may
          consist only of labor, materials, permits, and working drawings
          necessary to prepare and equip the 4th Floor Premises for such use.
          Any such change in the Work and/or Tenant's use of the 4th Floor
          Premises shall in no way affect (i) Tenant's right to the receipt of
          the Construction Credit provided for herein, (ii) Tenant's obligations
          regarding the Work set forth in paragraph 2.01 of this Amendment, and
          (iii) Landlord's rights set forth in paragraph 2.01 of this Amendment
          including, but not limited to, approval of contractor qualifications,
          approval of Tenant's Plans, and the right to supervise all
          construction operations on the 4th Floor Premises.

               D.  Construction Status and Confirmation. The Landlord reserves
          the right from time to time, but not more often than monthly, to
          require Tenant to furnish partial or final lien waivers (as
          applicable) and sworn contractors'
          
                                       3


<PAGE>
 
          statements and all other reasonable information Landlord may request,
          in writing, so as to enable Landlord to determine the status of 
          (i) the preparation or modification of Tenant's Plans; (ii) all 
          contracts let or to be let in relation to the Work; (iii) the cost of
          all Work, including the cost of any extras or modifications requested
          by Tenant after Landlord's approval of Tenant's Plans; (iv) the status
          of completion of the Work; (v) the status of payment to all 
          contractors, subcontractors and materialmen in relation to the Work;
          (vi) the status of Tenant's obligations to obtain partial and final
          lien waivers, as the situation may require, from all contractors,
          subcontractors and materialmen in relation to the Work; and (vii) the
          status of any adverse claims or disputes with contractors,   
          subcontractors or materialmen in relation to the Work. The Tenant 
          shall furnish such information as Landlord may reasonably require to
          evidence the foregoing no later than fifteen (15) days subsequent to  
          the date the Landlord requests the same, in writing.

               E.  Non-Applicable Provisions. The provisions of subparagraphs 2A
          through 2H of the Lease shall not be applicable to the construction of
          the 4th Floor Premises."

     3.  The following is hereby inserted into the Lease as Paragraph 3J and 3K:

               "J.  Notwithstanding the foregoing provisions of this Paragraph 
          3, the "Commencement Date" with respect to the 4th Floor Premises
          (sometimes referred to herein as the "4th Floor Premises Commencement
          Date") shall be January 12, 1995. Tenant's obligation to pay Rent and
          Operating Expenses allocable to the 4th Floor Premises shall commence
          as of the 4th Floor Premises Commencement Date.

               K.  The Term, which is currently scheduled to expire on March 31,
          2005, shall be coterminous with respect to the entire Premises."

     4.  Paragraph 4A of the Lease is hereby deleted, and the following inserted
in lieu thereof:

          "A.  "Base Rent"

               (i)  "Original Base Rent". For the Original Premises, the sum 
          equal to the number of RSF within the Original Premises times $21.00
          per RSF for each twelve month period during the Term of this Lease
          ("Original Annual Base Rent"). Such Original Annual Base Rent shall
          be paid in monthly installments of one-twelfth (1/12) of the 
          then-current Original Annual Base Rent in advance on or before the 
          first day of each and every month during the Term ("Original Monthly
          Base Rent"), as the Original Annual Base Rent or Original Monthly Base
          Rent may be adjusted pursuant to Paragraph 5 of this Lease.

               (ii)  "Additional Base Rent". For the Additional Premises, the 
          sum equal to the number of RSF within the Additional Premises (A) 
          $18.50 per

<PAGE>
 
          RSF for the first (1st) through the fifth (5th) Lease Years (as      
          defined in Section 5A) during the Term (B) $22.50 per RSF for the
          sixth (6th) through tenth (10th) Lease Years during the Term and
          (C) $25.50 per RSF for the eleventh (11th) through fifteenth (15th)
          Lease Years during the Term ("Additional Annual Base Rent"). Such
          Additional Annual Base Rent shall be paid in monthly installments
          of one-twelfth (1/12) of the then current Additional Annual Base
          Rent in advance on or before the first day of each and every month
          during the Term ("Additional Monthly Base Rent"), as the Additional
          Annual Base Rent or Additional Monthly Base Rent may be adjusted

               (iii)  "16th Floor Base Rent". For the 16th Floor Premises

          (66) months following the 16th Floor Premises Commencement Date, and
          (B) $29.89 per RSF for the remainder of the initial Term. Such 16th
          Floor Annual Base Rent shall be paid in monthly installments of

     5.  Paragraph 5B of the Lease is hereby deleted and the following inserted 
in lieu thereof:

          "B.  Rent Adjustments. The Annual Base Rent (excluding the 16th Floor
          Annual Base Rent and the 4th Floor Annual Base Rent) for each and 
          every Lease Year during the term of this Lease (the "Subject Lease
          Year") shall be adjusted (subject to the limitations hereinafter set
          forth) by an amount equal to the following (the "Rent Adjustment"):

               (i)  For the Base Year (and first full Lease Year if the Base 
          Year commences subsequent to July 1 of such year), an amount equal to
          the lesser of

                                       5
     
<PAGE>
 
          (a) the product of thirty percent (30%) of the Base Rent (excluding
          the 16th Floor Annual Base Rent and the 4th Floor Annual Base Rent)
          paid during the Base Year multiplied by the percentage change
          (positive or negative) of the CPI for the month in which the Term of
          this Lease commences over the CPI for the month in which this Lease
          was executed, and (b) $1.00 per RSF; and

               (ii)  For each Lease Year thereafter, an amount equal to the 
          product of thirty percent (30%) of the Annual Base Rent (excluding the
          16th Floor Annual Base Rent and the 4th Floor Annual Base Rent) plus
          the sum determined by subparagraph B(i) above multiplied by the
          percentage change (positive or negative) of the CPI for January of the
          Subject Lease Year over the CPI for the first full month of the Base
          Year; provided, however, that for any Lease Year the amount of the
          annual Rent Adjustment made by reason of changes in the CPI shall not
          exceed three percent (3%) of the adjusted Annual Base Rent (excluding
          the 16th Floor Annual Base Rent and the 4th Floor Annual Base Rent)
          for the immediately preceding Lease Year. The limitation set forth in
          the immediately preceding sentence shall not affect adjustments to
          Rent attributable to causes other than changes in the CPI.

          BB. 16th Floor Rent Adjustments. The 16th Floor Annual Base Rent shall
          be adjusted by an amount equal to the following (the "16th Floor Rent
          Adjustment"):

          For each Lease Year commencing with the Lease Year beginning 
          January 1, 1997, an amount equal to the product of $29.89 per RSF,
          multiplied by 35% of the percentage increase (if any) of the CPI for
          January of the Subject Lease Year over the CPI for the 66th month
          following the 16th Floor Premises Commencement Date.

          BBB.  4th Floor Rent Adjustments. The 4th Floor Annual Base Rent shall
          not be subject to Rent Adjustment."

     6.  As amended herein, the Lease shall remain in full force and effect and,
except as expressly amended herein, shall be unaffected hereby. In the event of 
any conflict between the provisions of this Amendment and the provisions of the 
Lease, the provisions of this Amendment shall control.

     7.  This Fifth Amendment to Agreement of Lease is executed by American 
National Bank and Trust Company, not personally, but in the exercise of the 
power and authority conferred upon and vested in it as Trustee. It is expressly 
understood and agreed that nothing herein shall be construed as creating any 
liability whatsoever against Trustee personally; and in particular, without 
limiting the generality of the foregoing, there shall be no personal liability 
to pay any indebtedness accruing hereunder or to perform any covenant, either 
express or implied, herein contained, or to keep, preserve, or sequester any 
property and all personal liability of every sort, if any, is hereby expressly 
waived by said Tenant, and by every person now or hereafter claiming any right 
or security hereunder; and that, so far as the Trustee is

 
                                       6
<PAGE>
 
concerned, the owner of any indebtedness or liability accruing hereunder shall 
look solely to the assets of said property and the proceeds thereof for the 
payment thereof.

     8.  BROKERS.  Tenant represents that except for MIGLIN-BEITLER MANAGEMENT 
CORPORATION, it has not dealt with any real estate brokers in connection with 
this Fifth Amendment and, to its knowledge, no broker other than MIGLIN-BEITLER 
MANAGEMENT CORPORATION initiated or participated in the negotiation of this 
Fifth Amendment, submitted or showed the Fifth Expansion Space or any other 
space in the Building to Tenant or is entitled to any commission or fee in 
connection with this Fifth Amendment. Tenant hereby agrees to indemnify, defend,
and hold Landlord harmless from and against any and all claims of any other real
estate brokers for commissions or fees in connection with this Fifth Amendment 
who claim to have dealt with the Tenant. Landlord represents and warrants to 
Tenant that Landlord is not obligated to pay a real estate broker's fee or 
commission to anyone which could cause the rent hereunder or any rental rate 
applicable to the Premises to increase.

     9.  MERGER.  All negotiations, considerations, representations and 
understandings between Landlord and Tenant relating to this Fifth Amendment are 
incorporated herein and may be modified or altered only by agreement, in 
writing, between Landlord and Tenant. No modification, termination, or 
surrender of the Lease, as modified by this Fifth Amendment, or surrender of the
Premises (including the 4th Floor Premises) or any part thereof or of any 
interest therein by Tenant shall be valid or effective unless agreed to and 
accepted, in writing, by the Landlord and no act by any representative or agent 
of the Landlord other than delivery of such a written agreement and acceptance 
by the Landlord shall constitute agreement to and acceptance thereof. Any prior 
negotiations or intentions of the parties relating to this Fifth Amendment, 
whether oral or evidenced by written documentation dated prior to the date of 
this Fifth Amendment, are null and void, unless specifically incorporated herein
by reference.

     10.  LANDLORD'S EXONERATION.  Landlord's exoneration clause, as set forth 
in Section 39 of the Lease, is hereby incorporated herein by reference, as if 
fully set forth.

                     SIXTH AMENDMENT TO AGREEMENT OF LEASE

     This Sixth Amendment to Agreement of Lease (the "Amendment") is entered 
into by and between American National Bank and Trust Company of Chicago, not 
individually, but solely as Trustee under Trust Agreement dated April 5, 1990 
and known as Trust No. 110513-07 ("Landlord") and The Northern Trust Company, an
Illinois banking corporation ("Tenant") as of this 30th day of November, 1995.

                               WITNESSETH: THAT
     WHEREAS, American National Bank and Trust Company of Chicago, Trust No. 
65287 and Tenant are parties to a certain Agreement of Lease dated August 27, 
1985; and 

     WHEREAS, the Agreement of Lease was amended by (i) that certain First

Second Amendment to Agreement of Lease dated as of August 6, 1987, (iii) that
certain Third Amendment to Agreement of Lease dated as of May 20, 1988, (iv)
that certain Fourth Amendment to Agreement of Lease dated as of May 1, 1990, and
(v) that certain Fifth Amendment to Agreement of Lease dated as of January 12,

     WHEREAS, the Lease was assigned by American National Bank and Trust Company
of Chicago, Trust No. 65287 to Landlord by assignment dated April 6, 1990; and 

     WHEREAS, a dispute has arisen between Tenant and Landlord concerning the 
proper interpretation of the Rent Adjustment provisions in paragraph 5B of the 
Lease; and

     WHEREAS, Landlord and Tenant desire to further amend the Lease as 
hereinafter set forth to clarify paragraph 5B and to resolve their disputes with
respect thereto.



<PAGE>
    
     NOW, THEREFORE, in consideration of the foregoing and other good and 
valuable considerations, the receipt and sufficiency of which are hereby 
acknowledged, the parties hereto agree as follows:

     1.   Paragraph 5A of the Lease is hereby amended to add the following 
subparagraphs 5A(x) and 5A(xi):

               (x) "Adjusted Annual Base Rent" means Annual Base Rent as
          adjusted by the Rent Adjustment made pursuant to paragraph 5 of the
          Lease.

               (xi) "Incremental Rent Adjustment" means the portion of the Rent
          Adjustment for the Subject Lease Year which is in excess of the Rent
          Adjustment that was added to Annual Base Rent the preceding Lease
          Year.

     2.   Paragraph 5B of the Lease is hereby deleted and the following inserted
in lieu thereof:

          B. Rent Adjustments. The Annual Base Rent (excluding the 16th floor
     Annual Base Rent and the 4th floor Annual Base Rent) for each and every
     Lease Year during the term of this Lease (the "Subject Lease Year") shall
     be adjusted (subject to the limitations herein set forth ) as follows (the
     "Rent Adjustment"):

               (i) For the Base Year, an amount equal to an increase of $1.00
          per RSF, which is a one time adjustment that shall be added to Annual
          Base Rent in the Base Year only; and
 
               (ii) For each Lease Year thereafter, an amount equal to $.90 per
          RSF plus thirty percent (30%) of the product of (a) the Annual Base
          Rent (excluding the 16th floor Annual Base Rent and the 4th floor
          Annual Base Rent) plus $.90 per RSF, multiplied by (b) the percentage
          change (positive or negative) of the CPI for January of the Subject
          Lease Year over the CPI for the first full month of the Base Year;
          provided, however, that for any Lease Year the Incremental Rent
          Adjustment shall not exceed three percent (3%) of the Adjusted Annual
          Base Rent (excluding the 16th floor Annual Base Rent and the 4th floor
          Annual Base Rent) for the immediately preceding Lease Year. Any
          abatement in Annual Base Rent or Rent Adjustments provided by this
          Lease
 
                                      -2-

<PAGE>
    
         shall be applied to reduce the amount due and owing by Tenant after the
         amount of the Rent Adjustment for the Subject Year has been determined
         without regard to any past or present abatements. Neither the
         calculation of the amount of any Rent Adjustment nor the calculation of
         any limit on the amount of the Rent Adjustment provided in this
         paragraph shall include consideration of abatements in any component of
         the calculation.

     3.  As an aid to the interpretation of paragraph 5B of the Lease, attached 
as Exhibit A to this Amendment are sample calculations of the CPI adjustment.

     4.  As amended herein, the Lease shall remain in full force and effect and,
except as expressly amended herein, shall be unaffected hereby. In the event of 
any conflict between the provisions of this Amendment and the provisions of the 
Lease, the provisions of this Amendment shall control.

     5.  This Sixth Amendment to Agreement of Lease is executed by American 
National Bank and Trust Company of Chicago, not personally, but in the exercise 
of the power and authority conferred upon and vested in it as Trustee of Trust 
No. 110513-07. It is expressly understood and agreed that nothing herein shall 
be construed as creating any liability whatsoever against Trustee, personally; 
and in particularly, without limiting the generality of the foregoing, there 
shall be no personal liability to pay any indebtedness accruing hereunder or to 
perform any covenant, either express or implied, herein contained, or to keep, 
preserve, or sequester any property and all personal liability of every sort, if
any, is hereby expressly waived by said Tenant and by every person now or 
hereafter claiming any right or security hereunder; and that, so far as 
the Trustee is concerned, the owner of any indebtedness or liability accruing 
hereunder shall look solely to the assets of said Property and the proceeds 
thereof for the payment thereof.

                             CONSULTING AGREEMENT


     This Consulting Agreement ("Agreement") is entered into as of this 1st day 
of October, 1995 between Northern Trust Corporation, a Delaware corporation 
having its principal place of business in Chicago, Illinois ("Corporation"), and
David W. Fox ("Consultant").

     WHEREAS, Consultant has served the Corporation as its Chief Executive 
Officer and Chairman of its Board of Directors, and the Corporation wishes to 
enter into a consulting relationship with Consultant upon his retirement from 
service to the Corporation; and

     WHEREAS, Consultant agrees to make himself available to provide consulting 
services to the Corporation, and Consultant desires to enter into a consulting 
relationship with the Corporation upon the terms and conditions hereinafter 
contained;

     NOW THEREFORE, in consideration of the covenants and agreements herein set 
forth and of the mutual benefits accruing to the Corporation and to Consultant 
from the consulting relationship to be established between the parties by the 
terms of this Agreement, the Corporation and Consultant agree as follows:

     1.  Consulting Relationship.

         Following Consultant's retirement and commencing on October 1, 1995, 
the Corporation hereby retains Consultant, and Consultant hereby agrees to be 
retained by the Corporation, as an independent consultant and not as an 
employee.

     2.  Consulting Services.

         Consultant agrees that during the term of this Agreement:

         A.  He will devote his best efforts to his position as an independent
             consultant to the Corporation and will perform such duties and
             execute the policies of the Corporation as determined by its Chief
             Executive Officer; provided that such duties and policies will not
             be inconsistent with the nature of the duties performed by
             Consultant during his active service with the Corporation as an
             officer and employee thereof;

         B.  Consultant shall exercise a reasonable degree of skill and care in 
             performing the services referred to in paragraph A above;
<PAGE>
 
          C.  Consultant shall be available to render services to the 
              Corporation under this Agreement but shall not be obligated to
              render in excess of 30 days of service per year during the term of
              this Agreement. Consultant shall not be obligated to render any
              services under this Agreement when he is unable to do so due to
              illness, disability or injury; and

          D.  Consultant shall be available for service hereunder upon receipt 
              of five days' written notice from the Corporation.

          E.  Consultant will be paid at a rate of $1,000 for each day of 
              service rendered to the Corporation during the term of this 
              Agreement.

     3.   Other Conditions.

          The Corporation shall, at its expense, provide Consultant with 
appropriate and sufficient office space and secretarial help in order to allow 
Consultant to perform his duties hereunder. Consultant shall have no authority 
over any employee or officer of the Corporation, except as may be necessary in 
the routine performance of his duties hereunder, nor shall the Corporation be 
required in any manner to implement any plans or suggestions Consultant may 
provide. Consultant shall also be entitled to reimbursement for reasonable out 
of pocket expenses incurred by Consultant in the performance of his duties 
hereunder.

     4.   Term.

          The term of this Agreement shall begin on October 1, 1995, and shall 
terminate on October 1, 2000; provided that in the event of Consultant's death 
or total disability this Agreement shall terminate as of the date of death or 
disability.

     5.   Renewal.

          This Agreement may be renewed for an additional term by the mutual 
written agreement of the parties.

     6.   Noncompete.

          During the term of this Agreement, Consultant shall not be associated,
directly or indirectly as employee, proprietor, partner, agent, representative,
officer, or otherwise, with the operation of any business that is competitive
with the financial services industry or any other business of the Corporation or
its affiliates in the State of Illinois or any state contiguous with the State
of Illinois. Notwithstanding the foregoing, Consultant may participate in the
affairs of any governmental, educational or other charitable institution, may
continue to serve as a director or

                                       2
<PAGE>
 
officer of all organizations which he served in any of those capacities at the 
time of his retirement, may engage in professional speaking and writing 
activities and may serve as a member of the board of directors of publicly held 
corporations as long as the Chief Executive Officer of the Corporation, in good 
faith, does not determine that such activities unreasonably interfere with the 
business of the Corporation or diminish Consultant's duties and obligations to 
the Corporation, and Consultant shall be entitled to retain all fees, royalties 
and other compensation derived from such activities; and provided further, that 
this Agreement shall not be construed to prevent Consultant from investing his 
personal funds in any form or manner he may choose that will not require any 
services on his part in the operation of or the affairs of the companies in 
which such investments are made which are competitive with the financial service
industry or any other business of the Corporation or its affiliates in the State
of Illinois or any state contiguous with the State of Illinois.

     7.   Confidentiality.

          Consultant acknowledged that, following his retirement from the 
Corporation, he continues to be bound by the terms of the "Northern Trust 
Corporation Statement of Policies and Procedures Regarding Confidential 
Information, Securities Trading by Employees and Related Matters" (the 
"Confidential Information Policy") and the "Northern Trust Corporation 
Information Asset Security Policy" (the "Information Asset Security Policy") and
agrees that these policies will also apply to any information learned by him in 
connection with the performance of his duties under this Agreement. Consultant 
will not disclose to or discuss with any person not employed by the Corporation 
or its affiliates any information of a type described as "confidential 
information" in the Confidential Information Policy or as "information assets" 
in the Information Asset Security Policy. This restriction will cease to apply 
to information that has become generally known or is already known to the person
or persons with whom it is to be discussed, other than through a breach of the 
Confidentiality Information Policy or the Information Asset Security Policy.

     8.   Relief.

          In the event of a breach or a threatened or intended breach of Section
5 or Section 6 of this Agreement by Consultant, the Corporation shall be 
entitled, in addition to remedies otherwise available to the Corporation at law 
or in equity, to injunctions, both preliminary and permanent, enjoining such 
breach or threatened or intended breach, and Consultant hereby consents to the 
issuance thereof forthwith in any court of competent jurisdiction. In addition, 
Consultant agrees to pay to the Corporation any costs and attorneys' fees 
reasonably incurred by the Corporation in connection therewith.

          The taking of any action by the Corporation or the forbearance of the 
Corporation to take any action shall not constitute a waiver by the Corporation 
of any of its rights to remedies or relief under this Agreement or under law or 
equity.

     9.   Complete Agreement.

          This Agreement represents the complete Agreement between the 
Corporation and Consultant concerning the subject matter hereof and supersedes 
all prior agreements or understandings, written or oral. No attempted
modification or waiver of any of the provisions hereof shall be binding on
either party unless in writing and signed by both Consultant and the
Corporation.

     10.  Notices.

          Any notice required or permitted to be given hereunder shall be in 
writing and shall be effective three business days after it is properly sent by 
registered or certified mail, if to the Corporation to its Secretary at the 
principal place of business of the Corporation, or if to Consultant to the

address as either party may from time to time designate by notice.

     11.  Assignability.

          This Agreement may not be assigned by either party without the prior 
written consent of the other party, except that no consent is necessary for the 
Corporation to assign this Agreement to a corporation succeeding to 
substantially all the assets or business of the Corporation, whether by merger, 
consolidation, acquisition or otherwise. This Agreement shall be binding upon 
Consultant, his heirs and permitted assigns and the Corporation, its successors 
and permitted assigns.

     12.  Severability.

          Each of the sections contained in this Agreement shall be enforceable 
independently of every other section in this Agreement, and the invalidity or 
nonenforceability of any section shall not invalidate or render nonenforceable 
any other section contained herein. If any section or provision in a section is 
found invalid or unenforceable, it is the intent of the parties that a court of 
competent jurisdiction shall reform the section or provision to produce its 
nearest enforceable economic equivalent.

     13.  Applicable Law.

          It is the intention of the parties hereto that all questions with 
respect to the construction and performance of this Agreement and the rights and
liabilities of the parties hereto shall be determined in accordance with the

                                                      TO 1995 FORM 10-K

                          NORTHERN TRUST CORPORATION

                            ANNUAL PERFORMANCE PLAN

                                     1995

I.     Purpose of Plan

       The purpose of the Annual Performance Plan (the "Plan") is to promote the
       achievement of superior financial and operating performance of the
       Northern Trust Corporation and its subsidiaries (hereinafter referred to
       as the "Corporation"), and further the objective of delivering unrivaled
       service quality to its clients and partners through the awarding of cash
       incentive payments to selected officers.

II.    Plan Year

       The Plan is effective from January 1, 1995 to December 31, 1995.

III.   Eligibility and Participation

       Eligibility to participate in the Plan is restricted to officers with the
       title of Vice President and above and who are not eligible for
       participation in a Specialized Incentive Plan. Plan participation is
       reviewed each year, and participation in one year does not automatically
       indicate participation in subsequent Plan years. Participation in the
       Plan is based upon recommendation from the respective Business Unit Head.

IV.    Award Funding and Determination

       At the beginning of each Plan year, the Compensation and Benefits
       Committee of the Board of Directors of the Corporation will determine a
       Corporate Earnings Target and profit plan funding for awards under the
       Annual Performance Plan. The allocation of the Plan award funding to each
       respective Business Unit will be based on the salaries of eligible
       officers with the Business Unit. Within each Business Unit, one-half of
       the available funding for awards under the Plan will be based on the
       Corporation's financial achievement versus the Corporate Earnings Target.
       The other half of the award funding is based on the financial achievement
       of the Business Unit versus the Business Unit's earnings target. For
       staff support personnel, the available funding for awards will be based
       entirely on the financial achievement of the Corporation versus the
       Corporate Earnings Target. The formula determining the pool level funding
       based on Corporate and Business Unit performance is described in
       Attachment I.

V.     Individual Award Determination

       Individual participant awards will be discretionary. They will be
       determined by Business Unit Management based on an assessment of
       individual performance, relative to performance expectations,
       contribution, competitive level of total compensation, and available
       award pool funding.



<PAGE>
 
VI.    Payment of Awards

       Awards will be paid in cash as soon as practicable following the
       completion of the Plan year. Awards payable because of a Change in
       Control of the Corporation pursuant to Paragraph VIII (h) shall be paid
       in cash as soon as practicable following such Change in Control.

VII.   Administration

       The Plan shall be administered by the Management Committee of the
       Corporation (the "Committee"). Subject to the provisions of the Plan, the
       Committee shall be authorized to interpret the Plan, to establish, amend
       and rescind any rules and regulations relating to the Plan, and to make
       all other determinations necessary or advisable for the administration
       of the Plan. The determinations of the Committee in the effective
       administration of the Plan, as described herein, shall be final and
       conclusive.

       The Board of Directors of the Corporation, by written resolution, may
       amend, suspend, or terminate any or all provisions of the Plan at any
       time.

VIII.  Other Provisions

       The following miscellaneous provisions are applicable to the Plan:

       (a)  Awards paid under the provisions of the Plan are considered 
            pensionable earnings when paid.

       (b)  Termination of employment by a participant during the Plan year,
            either voluntary or involuntary with cause, and for reasons other
            than death, disability, or retirement shall result in immediate
            exclusion from the Plan.

       (c)  Except in the event of the death of a participant, the rights and
            interests of a participant under the Plan shall not be assigned,
            encumbered, or transferred.

       (d)  No employee or other person shall have any claim or right to be
            granted an award under the Plan. Neither the Plan, nor any action
            taken thereunder, shall be construed as giving any employee or other
            person any right to be retained in the employ of the Corporation.

       (e)  The Corporation shall have the right to deduct from all payments
            made under the Plan any taxes required by law to be withheld with
            respect to such payment.

       (f)  All questions pertaining to the validity, construction and
            administration of the Plan and any award hereunder shall be
            determined in conformity with the laws of the State of Illinois.

                                       2

<PAGE>
 
       (g)  Each participant shall designate a beneficiary (the "Designated
            Beneficiary") to receive the award, if any, allocated to a
            participant, in the event of such participant's death. If no
            Designated Beneficiary survives the participant, it shall be the
            surviving spouse of the participant or, if there is no surviving
            spouse, it shall be the participant's estate.

       (h)  Notwithstanding any other terms contained herein, in the event of a
            Change in Control of the Corporation, discretionary awards shall be
            paid in accordance with the last sentence of Section V of this Plan
            and as if the Corporation and Business Units had achieved the
            respective earnings targets, as described in Section IV. For
            purposes of this paragraph, a "Change in Control" of the Corporation
            shall be deemed to occur on the earliest of:

            (i)    The receipt by the Corporation of a Schedule 13D or other
                   statement filed under Section 13(d) of the Securities
                   Exchange Act of 1934, as amended (the "Exchange Act"),
                   indicating that any entity, person, or group has acquired
                   beneficial ownership, as that term is defined in Rule 13d-3
                   under the Exchange Act, or more than 30% of the outstanding
                   capital stock of the Corporation entitled to vote for the
                   election of directors ("voting stock");

            (ii)   The commencement by any entity, person, or group (other than
                   the Corporation or a subsidiary of the Corporation) of a
                   tender offer or an exchange offer for more than 20% of the
                   outstanding voting stock of the Corporation;

            (iii)  The effective time of (A) a merger or consolidation of the
                   Corporation with one or more other corporations as a result
                   of which the holders of the outstanding voting stock of the
                   Corporation immediately prior to such merger or consolidation
                   hold less than 80% of the voting stock of the surviving or
                   resulting corporation, or (B) a transfer of substantially all
                   of the property of the Corporation other than to an entity of
                   which the Corporation owns at least 80% of the voting stock;
                   or

            (iv)   The election to the Board of Directors of the Corporation,
                   without the recommendation or approval of the incumbent Board
                   of Directors of the Corporation, or the lesser of (A) three
                   directors or (B) directors constituting a majority of the
                   number of directors of the Corporation then in office.

                         EMPLOYMENT SECURITY AGREEMENT
                         -----------------------------


     THIS EMPLOYMENT SECURITY AGREEMENT is entered into this ____________ day of
__________________, 1996, between NORTHERN TRUST CORPORATION, a Delaware
corporation (the "Company"), and
____________________________________________________ (the "Executive").

                                WITNESSETH THAT:
                                --------------- 

     WHEREAS, Executive is employed by the Company or one of its wholly-owned
subsidiaries (referred to collectively as the "Company") and the Company desires
to provide certain security to Executive in connection with any potential change
in control of the Company; and

     WHEREAS, the Company and the Executive entered into an Employment Security
Agreement dated as of ________________, 19__ with respect to the Executive's
employment following a change in control of the Company (which agreement, as it
has been amended from time to time and supplemented by subsequent letter
agreements, is referred to in this Agreement as the "Prior Agreement"); and

     WHEREAS, the Executive and the Company wish to supersede the Prior
Agreement with this Agreement;

     NOW, THEREFORE, it is hereby agreed by and between the parties, for good
and valuable consideration the receipt and sufficiency of which are hereby
acknowledged, as follows:

1.   Payments and Benefits Upon a Change in Control.  If within two (2) years
     after a Change in Control (as defined below) or during the Period Pending a
     Change in Control (as defined below), (i) the Company shall terminate
     Executive's employment with the Company without Good Cause (as defined
     below), or (ii) Executive shall voluntarily terminate such employment with
     Good Reason (as defined below), the Company shall, within 30 days of
     Executive's Employment Termination (as defined below), make the payments
     and provide the benefits described below.

     (a)  Cash Payment.  The Company shall make a lump sum cash payment to
          Executive equal to three times the Executive's Annual Compensation 
          (as defined below).

     (b)  Short-Year Bonus.  The Company shall make a lump sum cash payment to
          Executive equal to a pro rata portion (based on the date on which
          Executive's Employment Termination occurs) of the average of the
          annual amounts paid to Executive under the Management Performance Plan
          or any successor plan (the "MPP"), the Annual Performance Plan or any
          successor plan (the "APP"), the Specialized Incentive Plans or any
          successor plans (the "SIP") and any other cash-based incentive or
          bonus plans, with respect to the last three full fiscal years of
          Executive's participation in such plans prior to Employment
          Termination or, if higher, prior to the Change in Control.  For
          purposes of the preceding sentence, if Executive's number of full
          fiscal years of participation in the MPP, APP, SIP, and other cash-
          based plan prior to the Change in Control is less than three, the
          average amount shall be calculated as the average of the annual
          amounts paid to Executive over the number of full fiscal years of
          Executive's participation in the MPP, APP, SIP, and other plans prior
          to the

                                      -1-
<PAGE>
 
          Change in Control, or the number of full fiscal years of Executive's
          participation in the MPP, APP, SIP, and other plans prior to
          Employment Termination, whichever produces a higher average annual
          amount.

     (c)  Welfare Benefit Plans.  With respect to each Welfare Benefit Plan (as
          defined below), for the period beginning on Executive's Employment
          Termination and ending on the earlier of (i) three years following
          Executive's Employment Termination, or (ii) the date Executive becomes
          covered by a welfare benefit plan or program maintained by an entity
          other than the Company which provides coverage or benefits at least
          equal, in all respects, to such Welfare Benefit Plan, Executive shall
          continue to participate in such Welfare Benefit Plan on the same basis
          and at the same cost to Executive as was the case immediately prior to
          the Change in Control (or, if more favorable to Executive, as was the
          case at any time hereafter), or, if any benefit or coverage cannot be
          provided under a Welfare Benefit Plan because of applicable law or
          contractual provisions, Executive shall be provided with substantially
          similar benefits and coverage for such period. Immediately following
          the expiration of the continuation period required by the preceding
          sentence, Executive shall be entitled to continued group health
          benefit plan coverage (so-called "COBRA coverage") in accordance with
          Section 4980B of the Internal Revenue Code of 1986, as amended (the

          portion of all performance shares awarded to Executive but not then
          credited to Executive's performance share account will be immediately
          distributed to Executive; and (iii) Executive will remain eligible for
          crediting to Executive's performance share account as of the end of
          the performance period, in accordance with the provisions of the LTIP

          violation involving dishonesty, fraud, or breach of trust; (ii)
          Executive's willful engagement in any misconduct in the performance of
          Executive's duty that materially injures the Company; (iii)
          Executive's performance of any act which, if known to the customers,

          subsidiaries, would materially and adversely impact on the business of
          the Company or any of its subsidiaries; (iv) any act or omission by
          Executive that causes a regulatory body with jurisdiction over the
          Company or any of its subsidiaries, to demand, request, or recommend
          that Executive be suspended or removed from any position in which
          Executive serves with the Company or any of its subsidiaries; or (v)
          Executive's willful and substantial nonperformance of assigned duties,
          provided that such nonperformance has continued more than ten days
          after the Company has given written notice of such nonperformance and
          of its intention to terminate Executive's employment because of such
          nonperformance.

     (b)  "Good Reason" shall exist if, without Executive's express written
          consent:

          (i)    The Company shall materially reduce the nature, scope, level or
                 extent of Executive's responsibilities from the nature, scope,
                 level or extent of such responsibilities prior to the Change in
                 Control, or shall fail to provide Executive with adequate
                 office facilities and support services to perform such
                 responsibilities;

          (ii)   The Company shall reduce Executive's salary below that in

          (iii)  The Company shall require Executive to relocate Executive's
                 principal business office or his principal place of residence

                 Metropolitan Statistical Area (the "Geographical Employment
                 Area"), or assign to Executive duties that would reasonably
                 require such relocation;

                                      -3-
<PAGE>
 
          (iv)   The Company shall require Executive, or assign duties to
                 Executive which would reasonably require Executive, to spend
                 more than fifty normal working days away from the Geographical
                 Employment Area during any consecutive twelve-month period; or

          (v)    The Company shall fail to continue in effect any cash or stock-
                 based incentive or bonus plan, retirement plan, welfare benefit
                 plan, or other benefit plan, program or arrangement, unless the
                 aggregate value (as computed by an independent employee
                 benefits consultant selected by the Company) of all such
                 compensation, retirement and benefit plans, programs and
                 arrangements provided to Executive is not materially less than
                 their aggregate value as of the date of this Agreement (or as
                 of the Change in Control, if greater).

     (c)  "Change in Control" shall be deemed to occur on the earliest of:

          (i)    The receipt by the Company of a Schedule 13D or other statement
                 filed under Section 13(d) of the Securities Exchange Act of
                 1934, as amended (the "Exchange Act"), indicating that any
                 entity, person, or group has acquired beneficial ownership, as
                 that term is defined in Rule 13d-3 under the Exchange Act, of
                 more than 30% of the outstanding capital stock of the Company
                 entitled to vote for the election of directors ("voting
                 stock");

          (ii)   The commencement by an entity, person, or group (other than the
                 Company or a subsidiary of the Company) of a tender offer or an
                 exchange offer for more than 20% of the outstanding voting
                 stock of the Company;

          (iii)  The effective time of (A) a merger or consolidation of the
                 Company with one or more other corporations as a result of
                 which the holders of the outstanding voting stock of the
                 Company immediately prior to such merger or consolidation hold
                 less than 60% of the voting stock of the surviving or resulting
                 corporation, or (B) a transfer of substantially all of the
                 property of the Company other than to an entity of which the
                 Company owns at least 80% of the voting stock; or

          (iv)   The election to the Board of Directors of the Company, without
                 the recommendation or approval of the incumbent Board of
                 Directors of the Company, of the lesser of: (A) three
                 directors; or (B) directors constituting a majority of the
                 number of directors of the Company then in office.

     (d)  "Annual Compensation" shall mean the sum of: (i) Executive's salary
          at the greater of (A) Executive's salary rate in effect on the date of
          the Change in Control, or (B) Executive's salary rate in effect on
          Executive's Employment Termination; and (ii) the Amounts Payable Under
          Any Cash Bonus Plans (as defined below) in which Executive
          participates.

     (e)  "Employment Termination" shall mean the effective date of: (i)
          Executive's voluntary termination of employment with the Company with
          Good Reason; or (ii) the termination of Executive's employment by the
          Company without Good Cause.

                                      -4-
<PAGE>
 
     (f)  "Welfare Benefit Plan" shall mean each welfare benefit plan maintained
          or contributed to by the Company, including, but not limited to a plan
          that provides health (including medical and dental), life, accident or
          disability benefits or insurance, or similar coverage, in which
          Executive was participating at the time of the Change in Control.

     (g)  "Amounts Payable Under Any Cash Bonus Plans" shall mean the sum of
          whichever of the following are applicable to Executive:  (i) the
          amount that would be awarded to Executive under the MPP, assuming the
          target award percentage was applicable and Executive was employed for
          the full fiscal year in which Executive's Employment Termination
          occurs; (ii) the average of the annual amounts paid to Executive under
          the APP with respect to the last three full fiscal years of
          Executive's participation in the APP prior to Employment Termination
          or, if higher, prior to the Change in Control; (iii) the average of
          the annual amounts paid to Executive under the SIPs with respect to
          the last three full fiscal years of Executive's participation in the
          SIPs prior to Employment Termination or, if higher, prior to the
          Change in Control; and (iv) the average of the annual amounts paid to
          Executive under any other cash-based incentive or bonus plans in which
          Executive participates after the date of this Agreement with respect
          to the last three full fiscal years of Executive's participation in
          such plans prior to Employment Termination or, if higher, prior to the
          Change in Control.  For purposes of the preceding sentence, if
          Executive's number of full fiscal years of participation in the APP,
          SIP, or other cash-based plan prior to the Change in Control is less
          than three, the amount under clause (ii), (iii) or (iv) of this
          paragraph shall be calculated as the average of the annual amounts
          paid to Executive over the number of full fiscal years of Executive's
          participation in the APP, SIP, or other plans prior to the Change in
          Control, or the number of full fiscal years of Executive's
          participation in the APP, SIP, or other plans prior to Employment
          Termination, whichever produces a higher average annual amount.

     (h)  "Period Pending a Change in Control" shall mean the period after the
          approval by the Company's stockholders and prior to the effective time
          of (A) a merger or consolidation of the Company with one or more other
          corporations as a result of which the holders of the outstanding
          voting stock of the Company immediately prior to such merger or
          consolidation hold less than 60% of the voting stock of the surviving
          or resulting corporation, or (B) a transfer of substantially all of
          the property of the Company other than to an entity of which the
          Company owns at least 80% of the voting stock.

3.   Certain Additional Payments by the Company.
    

     (a)  Gross-Up.  Anything in this Agreement to the contrary notwithstanding,
          in the event that any payment or distribution by or on behalf of the
          Company to or for the benefit of Executive (whether paid or payable or
          distributed or distributable pursuant to the terms of this Agreement
          or otherwise, but determined without regard to any additional payments
          required under this Section 3) (the "Payments") is determined to be an
          "excess parachute payment" pursuant to Code Section 280G or any
          successor or substitute provision of the Code, with the effect that
          Executive is liable for the payment of the excise tax described in
          Code Section 4999 or any successor or substitute provision of the
          Code, or any interest or penalties are

                                      -5-
<PAGE>
 
          incurred by Executive with respect to such Payments (such excise tax,
          together with any such interest and penalties, are hereinafter
          collectively referred to as the "Excise Tax"), then Executive shall be
          entitled to receive an additional payment (the "Gross-Up Payment") in
          an amount such that after payment by Executive of all taxes imposed
          upon the Gross-Up Payment, including, without limitation, federal,
          state, local or other income taxes, FICA taxes, and additional Excise
          Tax (and any interest and penalties imposed with respect to such
          taxes), Executive retains a portion of the Gross-Up Payment equal to
          the Excise Tax imposed upon the Payments.

     (b)  Determination of Gross-Up.  Subject to the provisions of Section 3(c),
          all determinations required to be made under this Section 3, including
          whether and when a Gross-Up Payment is required and the amount of such
          Gross-Up Payment and the assumptions to be utilized in arriving at
          such determination, shall be made by the public accounting firm that
          serves as the Company's auditors (the "Accounting Firm"), which shall
          provide detailed supporting calculations both to the Company and
          Executive within 15 business days of the receipt of notice from the
          Company or Executive that there have been Payments, or such earlier
          time as is requested by the Company.  In the event that the Accounting
          Firm is serving as accountant or auditor for the individual, entity or
          group effecting the Change in Control, Executive shall designate
          another nationally recognized accounting firm to make the
          determinations required hereunder (which accounting firm shall then be
          referred to as the Accounting Firm hereunder).  All fees and expenses
          of the Accounting Firm shall be borne solely by the Company.  Any
          Gross-Up Payment, as determined pursuant to this Section 3, shall be
          paid by the Company to Executive within five days after the receipt by
          the Company and Executive of the Accounting firm's determination.  If
          the Accounting Firm determines that no Excise Tax is payable by
          Executive, it shall furnish Executive with a written opinion that
          failure to report the Excise Tax on Executive's applicable federal
          income tax return would not result in the imposition of a negligence
          or similar penalty.  Any determination by the Accounting Firm shall be
          binding upon the Company and Executive, except as provided in
          paragraph (c) below.

     (c)  IRS Claims.  As a result of the uncertainty in the application of
          Section 4999 of the Code at the time of the initial determination by
          the Accounting Firm hereunder, it is possible that the Internal
          Revenue Service or other agency will claim that a greater Excise Tax
          is due, and thus a greater amount of Gross-Up Payment should have been
          made by the Company than that determined pursuant to paragraph (b)
          above (an "Underpayment").  In the event that Executive is required to
          make a payment of any such Excise Tax, the Accounting Firm shall
          determine the amount of the Underpayment that has occurred, if any,
          and such Underpayment shall be promptly paid by the Company to or for
          the benefit of the Executive.  Executive shall notify the Company in
          writing of any claim by the Internal Revenue Service or other agency
          that, if successful, would require the payment by the Company of the
          Gross-Up Payment or an Underpayment.

4.   Mitigation and Set-Off.  Executive shall not be required to mitigate
     Executive's damages by seeking other employment or otherwise.  The
     Company's obligations under this Agreement shall not be reduced in any way
     by reason of any compensation or benefits received (or foregone) by
     Executive from sources other than the Company after Executive's Employment
    
                                      -6-
<PAGE>
 
     Termination, or any amounts that might have been received by Executive in
     other employment had Executive sought such other employment.  Executive's
     entitlement to benefits and coverage under this Agreement shall continue
     after, and shall not be affected by, Executive's obtaining other employment
     after his Employment Termination, provided that any such benefit or
     coverage shall not be furnished if Executive expressly waives the specific
     benefit or coverage by giving written notice of waiver to the Company.

5.   Litigation Expenses.  The Company shall pay to Executive all out-of-pocket
     expenses, including attorneys' fees, incurred by Executive in the event
     Executive successfully enforces any provision of this Agreement in any
     action, arbitration or lawsuit.

6.   Assignment; Successors.  This Agreement may not be assigned by the Company
     without the written consent of Executive but the obligations of the Company
     under this Agreement shall be the binding legal obligations of any
     successor to the Company by merger, consolidation or otherwise, and in the
     event of any business combination or transaction that results in the
     transfer of substantially all of the assets or business of the Company, the
     Company will cause the transferee to assume the obligations of the Company
     under this Agreement.  This Agreement may not be assigned by Executive
     during Executive's life, and upon Executive's death will inure to the
     benefit of Executive's heirs, legatees and legal representatives of
     Executive's estate.

7.   Interpretation.  The validity, interpretation, construction and performance
     of this Agreement shall be governed by the laws of the State of Illinois,
     without regard to the conflict of law principles thereof.  The invalidity
     or unenforceability of any provision of this Agreement shall not affect the
     validity or enforceability of any other provision of this Agreement.

8.   Withholding.  The Company may withhold from any payment that it is required
     to make under this Agreement amounts sufficient to satisfy applicable
     withholding requirements under any federal, state or local law.

9.   Amendment or Termination.  This Agreement may be amended at any time by
     written agreement between the Company and Executive.  The Company may
     terminate this Agreement by written notice given to Executive at least two
     years prior to the effective date of such termination, provided that, if a
     Change in Control occurs prior to the effective date such termination, the
     termination of this Agreement shall not be effective and Executive shall be
     entitled to the full benefits of this Agreement.  Any such amendment or
     termination shall be made pursuant to a resolution of the Board.

10.  Financing.  Cash and benefit payments under this Agreement shall constitute
     general obligations of the Company.  Executive shall have only an unsecured
     right to payment thereof out of the general assets of the Company.
     Notwithstanding the foregoing, the Company may, by agreement with one or
     more trustees to be selected by the Company, create a trust on such terms
     as the Company shall determine to make payments to Executive in accordance
     with the terms of this Agreement.
     
11.  Severability.  In the event that any provision or portion of this Agreement
     shall be determined to be invalid or unenforceable for any reason, the
     remaining provisions of this Agreement shall be unaffected thereby and
     shall remain in full force and effect.

                                      -7-

12.  Other Agreements.  This Agreement supersedes and cancels the Prior
     Agreement, and all prior written or oral agreements and understandings
     relating to the terms of this Agreement or the Prior Agreement.

  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 each of the
states of 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 benefit
plan services company. The Corporation's three other Illinois banks 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 Fi-
nancial Statements and Consolidated Financial Statistics included herein.
 
RESULTS OF OPERATIONS
OVERVIEW. Net income for 1995 totaled a record $220.0 million, a 20.8% increase
from the $182.2 million earned in 1994 which in turn was 8.5% greater than the
$167.9 million earned in 1993.
On a fully diluted basis, net income per common share increased 17% to $3.70 in
1995, compared with net income per common share of $3.16 in 1994 and $2.95 in
1993.
The record 1995 net income performance, together with strong growth in equity,
produced a return on average common stockholders' equity of 17.6% compared with
16.6% in 1994 and 17.9% in 1993. The return on average assets was 1.13% in 1995
compared with 1.02% in 1994 and 1.07% in 1993.
1995 marks the eighth consecutive year of record earnings. Trust fees reached a
new high, surpassing $500 million, while trust assets under administration
reached $614 billion at December 31, 1995, up $115 billion from 1994. The
record earnings resulted from excellent growth in all of Northern Trust's
diversified revenue sources combined with strong expense control.
Primarily through the retention of earnings, stockholders' equity grew to $1.5
billion as compared to $1.3 billion at December 31, 1994 and $1.2 billion at
December 31, 1993.
The Board of Directors increased the quarterly dividend per common share 19.2%
in November 1995, to $.31 from $.26, for a new annual rate of $1.24. This is
the ninth consecutive year in which the dividend rate has been increased, and
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's strategy will focus on those businesses with the greatest
growth and profitability potential while continuing to emphasize service
quality, cost containment and the maximization of the benefits derived from its
investments in technology. Expense growth and capital expenditures are also
closely monitored to ensure that short- and long-term business strategies are
effectively supported. In early 1995, Northern Trust committed to control its
expense growth rate by taking approximately $50 million out of base expenses
over the next three years. Northern Trust met its goal for 1995 and now expects
to meet the balance of the three-year goal during 1996.

NONINTEREST INCOME. The success of Northern Trust's strategy of maintaining a
diverse revenue base is evidenced by the fact that noninterest income
represents 63% of its total taxable equivalent revenue, compared with 62% one
year ago, exclusive of the $28.5 million 1994 pretax gain on the sale of the
Corporation's 21% interest in Banque Scandinave en Suisse (BSS). Noninterest
income totaled $678.1 million in 1995, $633.4 million in 1994 and $553.8
million in 1993.
TRUST FEES. Trust fees accounted for nearly 75% of total noninterest income and
47% of total taxable equivalent revenue in 1995. Trust fees for 1995 increased
11% to $505.0 million from $453.4 million in 1994 which was up 12% from $404.8
million in 1993. Trust fees have increased at a compound growth rate of 13% for
the last five years. The increase in 1995 trust fees is principally the result
of growth in business from new and existing clients, particularly for
investment management, custody, retirement services and securities lending
services coupled with growth in stock and bond market values. The March 31,
1995 acquisition of The Beach Bank of Vero Beach, Florida (Beach Bank) and the
October 31, 1995 acquisition of RCB International, Inc. (RCB), an international
provider of institutional investment management services, contributed
approximately $6.1 million in trust fees in 1995. Contributing to the 1994 fee
growth were new business results in addition to the incremental impact of fees
contributed by Hazlehurst & Associates, Inc. (Hazlehurst), an April 1994
acquisition.
Fees are based on the market value of assets managed and administered,
transaction fees and 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 $4.6 billion in 1995
and $3.9 billion in 1994.
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, Corporate and Institutional Services (C&IS) and Personal Financial
Services (PFS). The discussion of trust activities in each of these business
units follows.
CORPORATE AND INSTITUTIONAL SERVICES. At December 31, 1995 trust assets under
administration in C&IS totaled $550.5 billion, an increase of 23% from $447.2
billion a year ago. Trust fees in C&IS increased 12% in 1995 to $257.5 million
from $230.1 million in 1994 which was up 18% from $195.0 million in 1993.
Northern Trust is a leading provider of Master Trust and Master Custody
services to large U.S. corporate, middle market, institutional and
international clients, and public and union retirement funds. In addition to
Master Trust and Master Custody, C&IS offers a comprehensive array of
retirement service and investment service products.
Large U.S. Corporate. Trust fees from the large U.S. corporate market segment
totaled $86.1 million in 1995. Trust fees for this segment in 1994 and 1993
totaled $81.4 million and $77.3 million, respectively. Assets under
administration totaled $186.5 billion at December 31, 1995 compared with $152.9
billion a year ago.
Much of the anticipated growth in retirement assets is expected to be from
defined contribution plans of U.S. corporations. Northern Trust believes that
it is well-positioned to benefit from this trend given its long-term
relationships with corporate sponsors, its family of institutional funds, and
the services offered through Hazlehurst.
Middle Market. Trust fees from the middle market segment totaled $25.3 million
in 1995. Trust fees for this segment in 1994 and 1993 totaled $25.1 million and
$22.4 million, respectively. Assets under administration totaled $19.0 billion
at December 31, 1995 compared with $17.1 billion a year ago. New business has
primarily been attributable to the sale of investment service products.
Effective January 1, 1996, the trust and banking activities of the middle
market segment transferred to the PFS business unit.
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
their 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. It is a
leading provider of custody services to foundations and endowments. Three of
the ten largest foundations are clients as are many of the largest endowment
funds in the United States. 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 1995, 1994 and 1993 totaled
$50.1 million, $48.0 million

  Management's Discussion and Analysis of Financial
  Condition and Results of Operations (continued)

and $43.4 million, respectively. Assets under administration at December 31,
1995 increased to $141.6 billion from $118.9 billion at December 31, 1994.
International. This segment is composed of non-U.S. clients from eighteen
countries and has had the highest compound growth rate for the last three years
when measured in terms of assets under administration and trust fees. At
December 31, 1995 assets under administration totaled $67.3 billion, up 40%
from $48.1 billion at year-end 1994, which in turn was up 51% over the previous
year-end. Trust fees for 1995 increased 18% to $33.9 million. This compares
with $28.8 million in 1994 which was up 56% from $18.4 million in 1993.
Northern Trust continues to invest in the required systems capabilities and
sub-custodial network necessary to capitalize on the growth opportunities
presented by the development of worldwide financial markets.
Retirement Services. Public and union retirement funds and the operations of
Hazlehurst are included in retirement services. In 1995 these activities
contributed $58.3 million in trust fees, compared with $46.8 million in 1994
and $33.5 million in 1993. At December 31, 1995, $104.7 billion of assets were
under administration versus $83.8 billion at December 31, 1994. Growth in this
area has been driven by increased funding of plans by state and local public
entities and the use of outside service providers as reporting requirements
have become more complex. Although the public and union retirement funds market
segment tends to be price sensitive, investments in technology have allowed
Northern Trust to compete effectively on the basis of both cost and quality of
service to the client. The services offered through Hazlehurst 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.
Investment Services. Investment management activities, securities lending, and
the operations of RCB are included in investment services. This group is
responsible for the managed portion of trust assets under administration that
are shown within the various market segments. Fees associated with these
activities, with the exception of RCB-related fees, are also shown within the
market segments. Total assets under management grew from $51.5 billion at year-
end 1994 to $67.2 billion at year-end 1995; $35.8 billion was direct asset
management while the remaining $31.4 billion was securities lending collateral.
Northern Trust accelerated in 1995 its positioning as a global, multi-asset
class manager with an expanded array of investment service and product
capabilities. Advisory services assist clients in defining and evaluating their
investment strategy. Investment products, developed by Northern Trust and
selected partners, help clients implement their investment strategies.
Information products, delivered through Passport, provide assistance in
monitoring conformance with investment policy guidelines. Northern Trust
continues to be ranked by Pensions and Investments magazine as one of the
largest institutional money managers in the U.S.
On October 31, 1995, Northern Trust completed its acquisition of RCB
International, Inc., which had $5.0 billion in assets under management at year-
end 1995 and provided $3.8 million in trust fees in 1995. RCB provides value-
added U.S. and international multiple manager programs to complement the
capabilities of Northern Trust in the fixed income, equity and short-term
markets.
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 securities lending program is
managed by Northern Trust and included in trust assets under management. The
growth in domestic and international lending fees, up 19% over 1994, reflects
an increase in the volume of securities loaned. The cash collateral totaled
$31.4 billion and $26.4 billion at December 31, 1995 and 1994, respectively.
During the first quarter of 1995, Northern Trust commenced operations in its
new Hong Kong subsidiary to better facilitate the lending of securities from
its clients' global portfolios. Also in 1995, additional investment options
were made available to those clients participating in the securities lending
program thereby allowing clients to have more control over the degree of
investment risk which they assume.
Custody Services. With respect to the basic custody service product, price
competition has remained intense in all segments of the corporate trust
business. Northern Trust believes that it is positioned to deal with these
pressures and maintain acceptable profitability because of its focus on
providing unrivaled service quality, developing deeper client relationships
that include services other than basic custody, economies of scale and
technological innovation.
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. Through its worldwide network of subcustodians in
66 countries, Northern Trust had global assets of approximately $85 billion
under administration at December 31, 1995 which is 30% greater than last year.

PERSONAL FINANCIAL SERVICES. At December 31, 1995 trust assets under
administration in PFS totaled $63.4 billion, an increase of 23% from $51.4
billion at December 31, 1994. Trust fees increased 11% in 1995 to $247.5
million while 1994 trust fees totaled $223.3 million, an increase of 7% from
$209.8 million in 1993. Although all geographic markets contributed to the 1995
increase, the strongest fee growth occurred in the Wealth Management Group and
the Florida and Texas markets.
Northern Trust has positioned itself in states having significant
concentrations of wealth and growth potential, with a network of 52 locations
in Illinois, Florida, California, Arizona, and Texas as of February 1996. With
an established presence in these growing markets, Northern Trust believes that
it has the momentum to continue to grow personal trust fees.
Illinois. Personal trust fees in Illinois increased 8% to $124.0 million in
1995 from $114.7 million in 1994, which was up 5% from $109.8 million in 1993.
Over 40% of the increase in Illinois-based PFS fees is attributable to the
rapid growth in services provided by the Wealth Management Group. Northern
Trust's Wealth Management Group provides customized products and services to
meet the complex financial needs of families throughout the country with assets
typically exceeding $100 million. The moderate rate of growth in other trust
fees in Illinois is attributable, in part, to the maturity of the trust
business within the lead bank in Chicago. As assets are distributed or
liquidated from older trust accounts, revenues from the existing book of
business decline and partially offset the effect of new business. Northern
Trust has the leading market share in the Chicago area personal trust market.
Including the Wealth Management Group, total trust assets under administration
totaled $40.1 billion at December 31, 1995 compared with $32.8 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. The personal trust business in Florida continues to be a significant
contributor to the growth in personal trust fees. Trust fees for 1995 totaled
$65.9 million, up 15% from $57.2 million in 1994 which was up 9% from $52.2
million in 1993. Included in the 1995 results is $2.3 million of fees
contributed by Beach Bank, a March 31, 1995 acquisition. Trust assets under
administration were $13.2 billion at December 31, 1995, and $10.3 billion at
year-end 1994. The five-year compound growth rates for trust fees and trust
assets have been 13% and 15%, respectively. With two new offices in Vero Beach
and one each in Bradenton, Bonita Springs and Delray Beach, Northern Trust now
has twenty-one offices located in coastal communities encompassing the southern
half of the state. Management believes there remains significant opportunity
for growth in the markets currently served in Florida.
California. Northern Trust's California subsidiary has six offices
strategically located throughout the state to reach the California trust
market. Trust fees for 1995 increased 9% to $37.0 million from $34.0 million in
1994 which was up 5% from $32.3 million in 1993. Trust assets under
administration totaled $6.1 billion at December 31, 1995 and $5.3 billion at
December 31, 1994.
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. Trust fees from this market were $13.7 million in 1995,
$12.8 million in 1994 and $11.9 million in 1993. Assets under administration at
December 31, 1995 and 1994 totaled $2.1 billion and $1.7 billion, respectively.

  Management's Discussion and Analysis of Financial
  Condition and Results of Operations (continued)

Texas. Northern Trust expanded its presence in Texas during 1995 with the
acquisition of Tanglewood Bancshares, Inc., parent company of Tanglewood Bank
N.A. of Houston, in the third quarter. The two banking locations acquired now
provide trust services and complement Northern Trust's existing facilities,
positioning Northern Trust as a premier provider of personal trust and
financial services in this attractive market. With offices in Dallas and
Houston, Northern Trust Bank of Texas N.A. is located in the two most important
metropolitan markets in the state and has expanded from one office to six
offices since its entry into the Texas market in 1989. Trust fees for 1995,
1994 and 1993 were $6.9 million, $4.6 million and $3.6 million, respectively.
Trust assets under administration were $1.9 billion at December 31, 1995 and
$1.3 billion at December 31, 1994.
Investment Management. Northern Trust believes that its expertise in investment
management provides a competitive advantage in executing its personal trust
strategy. For example, investment management performance for bond accounts
remains in the top quartile for every cumulative performance period from one
through nine years ended December 31, 1995, as measured by SEI, a nationally
recognized plan sponsor consultant. Investment management performance for
equity accounts was solidly above the median for every cumulative performance
period from six through ten years ended December 31, 1995, 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 funds reached $3.6 billion at year-end. This mutual fund family serves the
investment needs of personal clients, while the Benchmark family of mutual
funds continues to serve the needs of institutional clients.
The national personal trust strategy will focus primarily on increasing market
share in present geographic locations and other selected upscale personal
markets. In Florida, expansion into additional counties is planned over the
next three to five years. This expansion will be achieved primarily de novo,
but may include selective acquisitions. In the newer growth areas around
Phoenix and Tucson, Arizona, there are plans to open new offices during the
course of the next several years. In Illinois, certain suburban communities
have been identified for new offices and an additional inner city location is
also contemplated.
SECURITY COMMISSIONS AND TRADING INCOME. Security commissions and trading
income totaled $21.7 million in 1995, compared with $22.0 million in 1994 and
$21.3 million in 1993. This income is primarily generated from securities
brokerage and futures contract services. Additional revenue is provided from
underwriting selected general obligation tax-exempt securities, security trades
and interest risk management activities with clients. The 1995 results reflect
modest growth in security brokerage activities offset by a decline in the
clearing volume of futures contracts.
OTHER OPERATING INCOME. Other operating income in 1995 totaled $150.4 million
compared with $158.1 million in 1994 and $125.9 million in 1993. The 1994
results included a $28.5 million pretax gain on the sale of 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 principal items included in other operating income are
foreign exchange trading profits and treasury management fees. Foreign exchange
trading profits totaled a record $55.3 million, up 54% from the $35.9 million
reported a year ago, which was up from $32.4 million in 1993. A substantial
component of foreign exchange profits resulted 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 established limits, produced an ancillary
component of aggregate trading profits. The fee portion of treasury management
revenues totaled $49.6 million in 1995, a 7% increase from the $46.3 million
reported in 1994 compared with $49.0 million in 1993. Total treasury management
revenues, which, in addition to fees, include the value of compensating deposit
balances, increased 6% to $77.5 million from $73.0 million in 1994 and $72.4
million in 1993. Other operating income in 1995 reflected losses of $.5 million
from the sale of mortgage loans, compared with gains of $.1 million in 1994 and
$3.9 million in 1993. Other operating income in 1995 also benefited from higher
fees on trust-related overnight advances offset by lower revenues from
operating other real estate owned (OREO) assets.
A significant portion of noninterest income is generated through trust,
treasury management, brokerage, check processing, payment and security
clearing, and other banking-related services. In providing these services,
which are principally paid for in fees rather than compensating balances,
Northern Trust, in addition to safekeeping and managing trust and corporate
assets, processed cash and security transactions exceeding $90 billion on
average each business day. Controls over such activities are closely monitored
to safeguard the assets of Northern Trust and its clients.
INVESTMENT SECURITY GAINS AND LOSSES. Net security gains totaling $1.0 million
were realized in 1995 primarily from held to maturity securities that were
called at a premium, in addition to $.1 million in gains from the sale of
securities classified as available for sale. This compares with net losses of
$.1 million in 1994 and $1.8 million in net gains in 1993.

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 noninterest-bearing
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 loans and OREO and client use
of compensating balances to pay for services.
Net interest income for 1995 was a record $357.6 million, up 7% from $334.6
million in 1994, which was up 2% from $327.9 million in 1993. 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 1995 was a
record $395.2 million, an increase of $27.2 million or 7% from $368.0 million
in 1994 which in turn was up 2% from $362.0 million in 1993. The growth in FTE
net interest income was essentially attributable to growth in average earning
assets, due in part to acquisitions, and was partially offset by a decline in
the net interest margin to 2.30% from 2.34% last year and 2.64% in 1993.
Earning assets averaged $17.2 billion, up 9% or $1.5 billion from the $15.7
billion reported in 1994, which was up from $13.7 billion in 1993.
Approximately 15% of the growth in earning assets resulted from the Beach Bank
and Tanglewood Bank acquisitions. Inclusive of these acquisitions, the growth
in average earning assets reflects a 10% or $820 million increase in loans, a
24% or $1.2 billion increase in securities and a 23% or $555 million decline in
money market assets. Loan volume for the year averaged $9.1 billion reflecting
a $921 million or 12% increase in domestic lending while international loans
decreased $101 million. The domestic growth came principally from residential
mortgage activities, up $446 million, and commercial and industrial loans, up
$365 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 $663 million in 1995, up 17% from a
year ago, resulting from domestic activity. Securities averaged $6.2 billion in
1995 versus $5.0 billion in 1994, due primarily to a $1.8 billion increase in
short-term federal agency and other marketable securities, offset in part by a
$554 million reduction in U.S. Government securities. Money market assets
averaged $1.9 billion in 1995 versus $2.4 billion in 1994, reflecting a
decrease in international deposit placement activity.

  Management's Discussion and Analysis of Financial
  Condition and Results of Operations (continued)

The increase in average earning assets of $1.5 billion was funded primarily by
growth in interest-bearing time deposits, which averaged $9.3 billion, up $1.0
billion. This growth was principally from savings certificates, up $771 million
due in large part to certificate of deposit marketing campaigns. Global custody
deposit activity in the London branch was up $103 million, while other foreign
time deposits increased $106 million. Other interest-related funds averaged
$5.2 billion, up $163 million, principally from securities sold under
agreements to repurchase (up $325 million) and federal funds purchased (up $213
million), and offset by a $375 million decline in senior notes and all other
borrowings. Average net noninterest-related funds increased $257 million,
mainly due to higher stockholders' equity and demand deposits. Stockholders'
equity for the year averaged $1.4 billion, an increase of $147 million or 12%
from 1994, principally due to strong earnings performance. The increase in
average demand deposits reflects higher levels of trust-related deposits and
balances resulting from acquisitions.
The net interest margin declined to 2.30% from 2.34% 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 resulting from a reduced
volume of residential mortgage refinancing activity. Also contributing to the
decline in the interest margin was the increase in the level of nonearning
trust-related overnight advances.
 
PROVISION FOR CREDIT LOSSES. Asset quality remained strong which resulted in
the provision for credit losses being unchanged from the prior year at $6.0
million, down from $19.5 million in 1993. For a discussion of the reserve for
credit losses, refer to pages 23 and 24.
 
NONINTEREST EXPENSES. Noninterest expenses for 1995 totaled $709.2 million, up
$8.7 million or 1% from $700.5 million in 1994, which was up 12% from $628.2
million in 1993. Total expenses included $10.3 million of incremental expenses
resulting from 1995 acquisitions. As a result of a reduction in premium rates,
FDIC insurance expense in 1995 declined by $7.7 million compared to last year.
Also included in the 1995 results is a $4.1 million pension settlement charge.
Noninterest expenses in 1994 included $30.9 million of nonrecurring charges.
Exclusive of all of these items for both years, 1995 noninterest expenses
increased 5% over last year. The majority of this increase was the result of
continued investment in technology and expansion of the personal trust and
banking office network.
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 151% for 1995 compared with 143% in 1994 and 146%
in 1993.
SALARIES AND BENEFITS. Salaries and benefits, which represent 59% of total
noninterest expenses, increased 7% to $419.1 million in 1995 from $391.4
million in 1994, which was up 8% from $361.5 million in 1993. Salary costs, the
largest component of noninterest expenses, totaled $337.6 million, up $21.0
million or 7% from $316.6 million a year ago. Included in the 1994 results was
a $4.2 million addition to salary expense relating to overtime back pay
obligations. The principal items contributing to the change in 1995 were merit
increases, incentive compensation, and staff additions from the Beach Bank,
Tanglewood Bank and RCB acquisitions, and to support Northern Trust's growing
global custody and retirement services activities. The record earnings
performance, together with the price increase in Northern Trust Corporation
stock, increased incentive-based compensation to $43.9 million, a 23% increase
from a year ago. Also contributing to the increase was $3.3 million in
severance costs associated with staff reductions.
Staff on a full-time equivalent (FTE) basis averaged 6,548 compared with 6,420
in 1994 and 6,318 in 1993. The growth in average staff during 1995 is a result
of acquisitions and staff additions in the last half of 1994 to support
Northern Trust's growing global custody, retirement services and mutual fund
activities. These additions were partially offset by staff reductions in other
areas of Northern Trust. As of December 31, 1995 staff levels on a FTE basis
totaled 6,531 compared to 6,608 at the end of last year. Adjusted for 179 posts
added through acquisitions, staff levels declined by approximately 4% during
the year.
Employee benefit costs for 1995 totaled $81.5 million, up $6.7 million or 9%
from $74.8 million in 1994 which was up 10% from $68.1 million in 1993. The
majority of the 1995 increase in benefit costs was attributable to higher
medical expenses, retirement benefit expenses and payroll taxes.
In conjunction with Northern Trust's commitment to control expense growth, a
complete review of all the employee benefit plans was conducted at the end of
1995. As a result of this review, changes, effective January 1, 1996, were made
to the pension, medical and Thrift Incentive plans. The Corporation will also,
subject to an Internal Revenue Service ruling and trustee approval, amend the
Employee Stock Ownership Plan. Although difficult to predict, with these
changes 1996 benefit expenses are expected to decline by approximately 5% from
the 1995 level.
OCCUPANCY EXPENSE. Net occupancy expense totaled $60.2 million, up 5% or $2.8
million from $57.4 million in 1994, which was up 4% from $55.3 million in 1993.
The principal components of the 1995 increase were higher building and
leasehold improvement amortization expenses, rental and operating costs
primarily associated with business expansion in Florida, Texas and Illinois.

EQUIPMENT EXPENSE. Equipment expense, which includes depreciation, rental, and
maintenance costs, totaled $48.6 million in 1995, down 14% or $7.8 million from
$56.4 million in 1994, which was 37% higher than the $41.1 million in 1993.
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 1995 totaled $181.3
million, down 7% from $195.3 million in 1994, which was up 15% from $170.3
million in 1993. Included in the 1995 results are a $4.1 million pension
settlement charge and a $.7 million expense for compensation payments pursuant
to a consent decree resolving the investigation by the Department of Justice
into the fair lending practices of Northern Trust's Illinois banking
subsidiaries. Other operating expenses in 1994 included a $9.6 million pension
settlement charge, 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. Excluding all of these items for both years, other
operating expenses decreased slightly from last year. Increases in computer
software amortization, transaction-based depository fees, technical and
consulting services, charitable contributions and postage were offset by lower
levels of FDIC deposit insurance premiums, lower costs associated with
operating other real estate owned assets, and a decline in costs incurred from
processing errors.
Investments in technology are designed to support and enhance the transaction
processing and securities handling capability of the trust and banking
businesses. Higher levels of capital expenditures for systems technology will
result in increasingly greater amounts of expense from future depreciation of
hardware and amortization of software. The depreciation and software
amortization are charged to equipment and other operating expenses,
respectively.
 
PROVISION FOR INCOME TAXES. The provision for income taxes was $100.5 million
in 1995 compared with $79.3 million in 1994 and $66.1 million in 1993. The
effective tax rate was 31% for 1995 compared with 30% for 1994 and 28% for
1993. The higher tax provision in 1995 resulted from the growth in earnings for
federal income tax purposes while federally tax-exempt income declined
slightly. Partially offsetting this increase was a decline in the state
provision for income taxes resulting from a higher level of state tax-exempt
income.
 
SUBSEQUENT IMPLEMENTATION OF STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS. Two
recently issued Statements of Financial Accounting Standards (SFAS) were
implemented as of January 1, 1996. The new statements are as follows:
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. No adjustments to the
carrying value of long-lived assets were required as a result of adopting this
statement.
SFAS No. 122, "Accounting for Mortgage Servicing Rights," applies to entities
that either purchase mortgage servicing rights or originate mortgage loans and
subsequently sell the mortgage loans with servicing rights retained. In either
case, the servicing rights must be capitalized as a separate asset and must be
evaluated for impairment based on their fair value. Since Northern Trust's held
for sale mortgage portfolio totaled $7.6 million as of January 1, 1996, the
impact of adopting this statement was immaterial.
Under SFAS No. 123, "Accounting for Stock-Based Compensation," the accounting
method for stock-based compensation, in particular for stock options, differs
from APB Opinion No. 25, under which most of the accounting requirements for
stock-based compensation were previously contained. The measurement and
recognition provisions of the statement are elective. An entity that continues
to apply Opinion No. 25 will be required to provide pro forma net income and
earnings per share, as if the accounting method in SFAS No. 123 had been used
for stock-based compensation costs. Northern Trust is currently in the process
of developing a stock option model to be used in calculating the pro forma
information required by SFAS No. 123. In 1996 Northern Trust will continue to
account for stock-based compensation in accordance with Opinion No. 25 and will
provide the pro forma information required by SFAS No. 123 for the year ended
December 31, 1995 and 1996 in the 1996 Annual Report.
 
CAPITAL EXPENDITURES
A committee of Northern Trust's senior officers reviews and approves proposed
capital expenditures which exceed $500,000. This process assures that the major
projects to

  Management's Discussion and Analysis of Financial
  Condition and Results of Operations (continued)

which Northern Trust commits its resources produce benefits compatible with
corporate strategic goals.
During 1995, Northern Trust continued to improve its hardware and software
capabilities, especially relating 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 key
improvements in securities processing operations and the creation of new client
statements. The unamortized, capitalized cost of this project at December 31,
1995 was $93 million. In addition, major systems development efforts in 1995
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. Northern Trust's 1996 technology initiatives will include
installation of the final phases of the trust management system, and the
continued development of Passport and retirement services products.
Capital expenditures in 1995 also included the leasehold improvements and
furnishings associated with the opening of new offices in Florida and the
construction costs for the Chicago South Financial Center and the new Winnetka,
Illinois office, both scheduled to open by mid-year 1996, as well as expansion
in several existing offices.
Capital expenditures for 1995 totaled $86 million of which $10 million was for
building and leasehold improvements, $3 million for furnishings, $26 million
for hardware and machinery and $47 million for software. During 1996, 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.
 
ASSET QUALITY AND CREDIT RISK
SECURITIES. A high quality securities portfolio is maintained with 87% 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, 1995, 73%
of these securities were rated triple-A or double-A, 24% 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, and asset-backed securities, collateralized by automobile loans
and credit card receivables.
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.
 
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
the credit exposure is well-diversified, there are certain significant groups
which 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: middle market companies
and

20 Northern Trust Corporation
<PAGE>
 
small businesses, broker-dealers of securities, banks and bank holding
companies, commercial real estate, and residential real estate.
 
MIDDLE MARKET COMPANIES AND SMALL BUSINESSES. Credit exposure to middle market
companies and small businesses is primarily in the form of commercial loans.
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.
Middle market and small business loans totaled approximately $1.2 billion at
December 31, 1995 and $945.5 million at December 31, 1994. Nonperforming middle
market loans totaled $1.3 million and $7.8 million at December 31, 1995 and
1994, respectively.
Credit exposure related to customer acceptance liabilities with middle market
companies and small businesses totaled $24.4 million and $20.3 million as of
December 31, 1995 and 1994, respectively. Off-balance sheet items related to
these entities in the form of legally binding commitments to extend credit,
standby letters of credit, and commercial letters of credit totaled $1.2
billion, $405.6 million, and $12.5 million, respectively, as of December 31,
1995, and $917.8 million, $378.7 million, and $17.8 million, respectively, as
of December 31, 1994.
 
BROKER-DEALERS OF SECURITIES. Broker loans consist primarily of overnight funds
loaned to broker-dealers in the securities industry on both a secured and an
unsecured basis. Broker loans averaged $269.0 million during 1995 and $355.7
million during 1994, and totaled $304.0 million at December 31, 1995 and $274.6
million at December 31, 1994. Securities purchased under agreements to resell
with broker-dealers at year-end totaled $30.0 million at December 31, 1995
compared with zero at December 31, 1994. Standby letters of credit issued on
behalf of broker-dealers and legally binding commitments to extend credit
totaled $148.4 million and $185.5 million, respectively, as of December 31,
1995, and $51.2 million and $161.7 million, respectively, as of December 31,
1994. Northern Trust may also have a limited amount of potential credit
exposure to brokers and dealers in connection with securities lending
activities.
 
BANKS AND BANK HOLDING COMPANIES. The following table shows the credit exposure
to banks and bank holding companies at December 31, 1995 and December 31, 1994.
Exposure to such entities is well-diversified geographically.
A significant portion of credit exposure to banks is in the form of liquid,
short-term money market assets. To minimize the credit risk related to these
transactions, the Credit Policy Committee sets limits on the amount of credit
exposure with counterparties and regularly assesses their financial condition.
In connection with securities purchased under agreements to resell, the value
of collateral held is continually monitored. Most of the domestic commercial
loans shown in the following table consisted of loans 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.
The international loan exposure represents transactions with major
international banks arising from trade finance and dollar clearing activities.

  Management's Discussion and Analysis of Financial
  Condition and Results of Operations (continued)
 
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
commercial real estate portfolio consists of interim loans and commercial
mortgages.
The interim loans 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 included in the portfolio 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 is also 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 market areas served by the subsidiary banks in suburban
Chicago and Florida.
Commercial real estate loans outstanding at December 31, 1995, are detailed in
the next table.

</TABLE>
 
 In comparison, commercial real estate loans at December 31, 1994 totaled
$494.1 million. Nonperforming commercial real estate loans totaled $9.0 million
in 1995 and $9.1 million in 1994. At December 31, 1995 commercial real estate
loans 90 days past due and still accruing interest totaled $12.1 million. Not
included in the table above was OREO which totaled $1.8 million and $2.2
million at December 31, 1995 and 1994, respectively.
At December 31, 1995, 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 $21.7 million and $16.5 million,
respectively. At December 31, 1994, legally binding commitments were $25.5
million and standby letters of credit were $47.2 million.
 
RESIDENTIAL REAL ESTATE. Residential real estate loans totaled $3.9 billion or
41% of total domestic loans at December 31, 1995, compared with $3.3 billion or
40% at December 31, 1994. Residential real estate loans consist of conventional
home mortgages, which generally require a loan to collateral value of 75% to
80%, and equity credit lines, which generally limit the loan to collateral
value to no more than 70% to 75%. Of the total $3.9 billion in residential real
estate loans, $2.4 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 $372.2 million and $377.0 million as of December 31, 1995 and
1994, respectively.
 
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, 1995. This compares with $154 million
to Germany in 1994 and $153 million to Canada in 1993.
 
NONPERFORMING ASSETS AND 90 DAY PAST DUE LOANS. Nonperforming assets consist of
nonaccrual loans, restructured loans and 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 below presents the nonperforming assets and past due loans for the
current year and the prior years. Of the total loan portfolio of $9.9 billion
at December 31, 1995, $31.9 million or .32% was nonperforming, an increase of
$4.1 million from year-end 1994. Nonperforming loans at December 31, 1995
consisted principally of commercial loans, including $9.0 million of commercial
real estate loans and $1.3 million to middle market and small business
companies. The net increase of $3.7 million in nonperforming assets resulted
from additions during 1995 of $31.1 million in new nonaccrual loans partially
offset by total gross charge-offs of $10.2 million, payments and loan sales of
$19.5 million, property sales with a basis of $2.9 million and $.4 million in
write-downs and realized losses on OREO assets. While the estimated carrying
value of the OREO portfolio is believed to be realizable, it is not possible to
predict whether such properties could continue to experience further declines
in value.
SFAS Nos. 114 and 118, "Accounting by Creditors for Impairment of a Loan," were
adopted effective January 1, 1995. These new statements require that an
impaired loan that is within the scope of this statement be measured based on
the present value of expected future cash flows discounted at the loan's
effective interest rate or at the loan's observable market price or, if the
loan is collateral dependent, based on the fair value of the collateral. 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, 1995, impaired
loans, which also have been classified as nonperforming, totaled $27.6 million,
with $1.0 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 and
approval 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;

volume; historical net loan loss experience; the level and composition of
nonaccrual, past due and restructured loans; other extensions of credit; 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.
While the largest portion of this reserve is typically intended to cover loan
and lease losses, it is considered a general reserve that is available for all
credit-related purposes. 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. Although the U.S. economy is still expanding, there continue to be
uncertainties in several industries. In addition, 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 other factors impacting management's analysis of the
adequacy of the reserve. The combination of these factors resulted in a reserve
for credit losses of $147.1 million at December 31, 1995, compared with $144.8
million last year. The decline in the year-end reserve for credit losses as a
percentage of outstanding loans and leases from 1.69% to 1.49% at year-end 1995
is primarily attributable to loan growth in low-risk residential lending and
overnight trust advances. The table above summarizes the changes in the reserve
for credit losses for the current year and the prior years.

FINANCIAL CONDITION
Average earning assets in 1995 increased 9% to $17.2 billion. Approximately 15%
of the growth in earning assets resulted from the Beach Bank and Tanglewood
Bank acquisitions. The growth, including acquisitions, was concentrated
primarily in short-term U.S. federal agency securities, residential mortgages
and commercial and industrial loans. A high quality and liquid balance sheet is
maintained with securities and money market assets averaging $8.1 billion or
47% 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
24% from last year to $6.2 billion. U.S. Government securities averaged $1.2
billion in 1995, down 31% from 1994 levels. U.S. Government securities had an
average maturity of eleven months at December 31, 1995, compared with ten
months at the prior year-end. Average municipal securities declined $30 million
to $435 million and provided a fully taxable equivalent yield of 10.75%. The
average maturity of municipal securities was 78 months, up from 64 months a
year ago. Federal agency securities averaged $4.1 billion in 1995, up $1.8
billion from 1994 and had an average maturity at December 31, 1995 and 1994 of
nine months and six months, respectively. Other securities, consisting
primarily of preferred stock, privately issued collateralized mortgage
obligations and asset-backed securities, averaged $353 million, $15 million
lower than last year. Included in other securities were $62 million of triple-A
rated collateralized mortgage obligations, $16 million of which were
collateralized by federal agency securities. Other asset-backed securities were
$26 million versus $65 million last year; these securities had an average
maturity of three months, versus eleven months a year ago. Approximately $1.3
billion of federal agency, asset-backed 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 1995, the fair value of the securities
portfolio of $5.8 billion exceeded the book value of these securities by $27.5
million.
Loans averaged $9.1 billion in 1995 and increased 10% from the prior year.
Average domestic loans increased 12% to $8.8 billion for the year while the
average international portfolio decreased to $344 million from $446 million in
1994. The increase in the average domestic loan portfolio reflects substantial
growth in residential mortgages which, net of $15.2 million in loan sales,
increased nearly $446 million on average to total $3.9 billion at year-end.
Commercial and industrial loans also contributed to the growth in the domestic
portfolio, increasing 14% on average to total $3.2 billion at year-end. During
the year commercial real estate loans increased slightly due primarily to
acquisitions, and at December 31, 1995, totaled $513 million or 5% of domestic
loans. The decrease in the international portfolio is partially attributable to
lower levels of trust client overnight advances.
Money market assets averaged $1.9 billion, down 23% or $555 million from last
year.
Total interest-related funds averaged $14.5 billion in 1995, up $1.2 billion or
9% from 1994. As a result of marketing campaigns, savings certificates of
deposit increased $771 million or 63% to $2.0 billion, partially offset by a
$73 million decline in average savings and money market deposits. Total federal
funds purchased increased $213 million or 16% to $1.6 billion. Securities sold
under agreements to repurchase increased $325 million on average to $1.8
billion. Foreign office time deposits increased $209 million or 6%, resulting
primarily from greater global custody activity. Deposits related to trust
activities in the domestic banking subsidiaries, coupled with growth of the
global custody business, had a significant impact on the balance sheet as these
deposits in 1995 averaged $4.6 billion or 37% of total deposits. Senior notes
averaged $394 million, down $388 million or 50% from last year.
During September 1995, The Northern Trust Company issued $100 million of 6.70%
Subordinated Notes due 2005. The notes were issued under the terms of a
September 6, 1995 Offering Circular allowing The Northern Trust Company to
offer from time to time up to $300 million aggregate principal amount of its
subordinated bank notes with maturities ranging from 5 years to 15 years 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.

FAIR VALUE DISCLOSURES
SFAS No. 107, "Disclosures About Fair Value of Financial Instruments," requires
disclosure of the estimated fair value of certain financial instruments. These
disclosures are presented in Note 17 on page 48. The fair value disclosures
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
Northern Trust's financial position. In addition, it is important to realize
that SFAS No. 107 requires the fair value of the demand, savings and money
market deposits to be recorded at their book value. Due to the interest rate
characteristics of these accounts--zero rate of interest or a relatively low
interest rate--the true values of these accounts to Northern Trust change in
response to changes in the level of interest rates and are not accurately
reflected in the fair value disclosures.
Considerable judgment is required to interpret the market data when computing
estimates of fair value. Accordingly, the estimates presented in Note 17 are
not necessarily indicative of the amounts that could have been realized in a
market exchange. 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 disclosure and those of other banks may
not be meaningful.
 
ASSET AND LIABILITY MANAGEMENT
The policies and guidelines for the management of Northern Trust's balance
sheet assets and liabilities are established by the Corporate Asset and
Liability Policy Committee (ALCO). ALCO monitors and establishes limits on the
sensitivity of net interest income 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 net interest income while maintaining a high quality balance
sheet and acceptable levels of interest rate sensitivity and liquidity risk.

26 Northern Trust Corporation
<PAGE>
 
INTEREST RATE RISK MANAGEMENT. Sensitivity of net interest income to interest
rate changes arises when yields on assets change in a different time period or
in a different proportion from that of 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 a reasonable level
of net interest income even in periods of volatile interest rates.
In the management of interest rate sensitivity, Northern Trust utilizes the
following measurement techniques: gap reporting, model simulation, and duration
analysis. These three techniques are complementary and are used in concert to
provide a more complete picture of interest rate risk.
The calculation of the interest sensitivity gap is shown in the following
table, which measures the timing mismatch 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 economic 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.

- -Assets and liabilities whose rates are variable are reported based on their
repricing dates. Those with fixed rates are reported based on their scheduled
contractual maturity dates, except for certain investment securities and loans
secured by 1-4 family residential properties that are based on anticipated
prepayments.

noninterest-bearing time deposits, savings accounts and NOW accounts are based
on historical and current experiences regarding product portfolio retention and
interest rate repricing behavior. The portion of these deposits which are
considered long-term and stable have been classified in the over 5 years
category; the remainder are classified in the 1-3 months category.
Model simulation is another important tool used to measure the sensitivity of
net interest income to interest rate changes. Using computer modeling
techniques, Northern Trust is able to measure the potential impact on net
interest income, assuming the continuation of current balance sheet trends,
different patterns of rate movements, and specific changes in the relationships
between various instruments on and off the balance sheet. Northern Trust uses
model simulation to measure its net interest income sensitivity relative to
management's most likely interest rate scenario. At December 31, 1995, this
scenario assumed a gradual decrease in interest rates during 1996. The interest
sensitivity is then tested by running alternative scenarios above and below the
most likely interest rate outcome. In 1995, this sensitivity

  Management's Discussion and Analysis of Financial
  Condition and Results of Operations (continued)

calculation was always less than 2.5% of the annual net interest income, 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 third technique that is used to measure interest rate sensitivity is
duration analysis. Duration analysis is a form of average life calculation used
to estimate the market risk inherent in financial instruments. Market risk is
the risk that the value of on- and off-balance sheet positions will be
adversely affected by rate movements. Northern Trust strives to limit aggregate
market risk to an acceptable level in the context of both risk-return and cost-
benefit trade-offs.
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.
 
DERIVATIVE FINANCIAL INSTRUMENTS USED FOR ASSET AND LIABILITY MANAGEMENT. A
derivative financial instrument is a contract or agreement whose value is
linked to or derived from changes in the value of an underlying asset or
underlying reference rate or index. Northern Trust utilizes various types of
derivative financial instruments, primarily interest rate swaps, as tools for
managing interest rate and option risk. 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, 1995. A key
assumption in the preparation of the table is that floating rates remain
constant at December 31, 1995 levels.
Some of the principal uses of derivative financial instruments, together with
the notional amounts outstanding, are described as follows:
CONVERT YIELDS ON GOVERNMENT AND AGENCY SECURITIES TO AN EFFECTIVE LIBOR RATE.
At December 31, 1995, interest rate swaps with a notional amount of $1.35
billion and purchased interest rate protection contracts with a notional amount
of $25 million were used to convert fixed and floating rate interest payments
on Government and agency securities (classified as Available for Sale) to
floating rate payments indexed to London Interbank Offered Rates (LIBOR). Swaps
with a notional amount of $930 million were combined with fixed rate
securities, $85 million were combined with floating rate securities indexed to
Treasury Bill rates, and $336 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 ASSETS 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 $949 million at December 31, 1995
to hedge the interest rate risk from fixed rate assets. For accounting purposes
these swaps were designated to either convert the fixed rate on the asset to an
effective floating rate or to convert floating rate funding to a fixed rate.
SWAPS COMBINED WITH NOTE ISSUANCE TO OBTAIN FAVORABLE FUNDING COSTS. Interest
rate swaps with a notional amount of $300 million at December 31, 1995 were
used in

conjunction with the issuance of senior notes and subordinated notes to obtain
desired funding characteristics. 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 using swaps to convert the rate
characteristics to meet its needs.
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 1995
were $30.4 million of forward foreign exchange contracts and $1.8 million of
short sales of foreign currency futures contracts.
HEDGING MORTGAGES HELD FOR SALE. Northern Trust hedged 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, 1995 the
portfolio was hedged with $11.1 million of forward sales of mortgage-backed
securities, $.7 million of short sales of Treasury Note futures, and $2.0
million of purchases of put options on Treasury Note futures.
 
COLLATERALIZED MORTGAGE OBLIGATIONS. Northern Trust invests in collateralized
mortgage obligations (CMOs), which are structured obligations that are derived
from a pool of mortgage loans or agency mortgage-backed securities. CMOs in
general have widely varying degrees of risk, which derives from the prepayment
risk on the underlying mortgage loans, but Northern Trust invests only in CMOs
that have lesser degrees of prepayment risk. CMOs are classified as available
for sale securities, and are used as part of normal securities portfolio
activities.
Investments in LIBOR-indexed floating rate CMOs had an amortized cost of $370.6
million and a fair value of $371.6 million as of December 31, 1995, compared
with an amortized cost of $439.2 million and a fair value of $436.4 million as
of December 31, 1994. The average life of these CMOs was 23 months based on an
average of dealer estimates of prepayment rates. Floating rate CMOs are
purchased to provide an attractive spread over short-term funding costs. The
primary risk with floating rate CMOs comes from caps on the floating rate.
Northern Trust's CMOs have rate caps which range from 9% to 13%, with a
weighted average of approximately 10%. These caps will affect the interest
margin only if short-term LIBOR rates rise by more than 350 basis points above
the year-end 1995 levels. Early payments of principal have little effect on the
earnings risk of floating rate CMOs, but slower than expected prepayment rates
would extend the exposure to the interest rate caps. A 300 basis point rise in
mortgage rates beyond those prevailing on December 31, 1995 would cause an
estimated increase in the average life of Northern Trust's floating rate CMOs
from 23 months to 41 months.
As of December 31, 1995 Northern Trust owned fixed rate CMOs with an amortized
cost of $60.9 million and a fair value of $60.1 million, compared with an
amortized cost of $68.7 million and a fair value of $65.6 million as of
December 31, 1994. The average life of the fixed rate CMOs was estimated to be
18 months as of December 31, 1995. A 300 basis point rise in rates is estimated
to cause the average life of the fixed rate CMOs to extend to approximately 22
months.
 
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 50% of
total assets. Further, at December 31, 1995, 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 $8.2
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 1996

equal to their 1996 eligible net profits plus $181 million. Bank subsidiary
dividends are subject to certain restrictions that are explained in Note 12 on
page 46. In September 1995, the Bank used a portion of the proceeds of a $100
million subordinated debt issue to repay $25 million of debt to the Corporation
and intends to repay the remaining $50 million of debt to the Corporation in
1996. The Corporation's liquidity, defined as the amount of marketable assets
in excess of commercial paper, was strong at $117 million at year-end 1995. The
cash flows of the Corporation are shown in Note 24 on page 55. 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
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 should help Northern Trust withstand
unforeseen adverse developments and take advantage of profitable investment
opportunities when they arise. In 1995, common equity increased 15% or $172
million reaching a record $1.3 billion at year end, while total risk-adjusted
assets rose 11%. Total equity as of December 31, 1995 was $1.5 billion
including $50 million of convertible preferred stock and $120 million of
auction rate preferred stock. In January 1996, the Corporation announced the
call for redemption of 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 1,198,372 shares of
common stock in connection with the conversion. The shares issued upon
conversion have been reflected in the Corporation's fully diluted shares, so
that conversion has no impact on fully diluted net income per common share.
In February 1994, the Board of Directors increased the Corporation's common
stock buyback authorization by approximately 1.3 million shares, thus allowing
the purchase after that date of up to an aggregate of 4 million shares of the
Corporation's common stock. During 1995 the Corporation purchased 1,486,159 of
its own shares as part of the buyback program, some of which were reissued in
connection with the RCB acquisition and the exercise of stock options. At
December 31, 1995, 2,269,756 additional shares may be purchased pursuant to
this program.
The Board of Directors increased the quarterly dividend by 19.2% to $.31 per
common share in November 1995. Over the last five years the common dividend has
increased 121%.
At December 31, 1995, tier 1 capital was 8.8% and total capital was 12.5% 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 6.2% is also well above the regulatory requirement of 3.0%.
In addition, each of the subsidiary banks had a ratio above 9.0% for tier 1
capital, 10.0% for total risk-based capital, and 5.6% for the leverage ratio.
The average rate declared on the $120 million of auction rate preferred stock
was 4.51% during 1995 versus 3.45% in 1994.

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 Branch 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 personal lending. 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,
common and preferred equity, holding company investments, and corporate
operating expenses. Noninterest income for 1994 included the net gain of $28.5
million from the sale of the interest in BSS. Noninterest expenses in 1995
include a $4.1 million pension settlement charge. 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 a pension settlement charge.
The following table reflects the earnings contribution of Northern Trust's
lines of business for the years ended December 31, 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 Bank. The Corporation also owns banks in each of
the states of Arizona, California, Florida and Texas, and various other nonbank
subsidiaries, including a brokerage firm and a futures commission merchant. The
other Chicago area banks 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 offered to middle market companies in Chicago and
the Midwest area, 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. These services
are delivered through the Bank and the network of subsidiaries in Florida,
Arizona, California, Texas and suburban Chicago. Effective January 1, 1996,
trust and banking services to middle market companies were transferred to the
PFS unit.
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 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 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 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

36 Northern Trust Corporation
<PAGE>
 
are also entered into to hedge specifically identified existing assets and
liabilities or anticipated transactions. If specific criteria are met, any
gains or losses are deferred and recognized as an adjustment to interest income
or expense over the life of the designated asset, liability, or anticipated
transaction. Interest accruals on interest rate swaps that are used as hedges
are recognized as adjustments to the interest income or expense of the hedged
item over the life of the swap.
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 and other
extensions of credit deemed uncollectible are charged to the reserve.
Subsequent recoveries, if any, are credited to the reserve. The loan 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. While the largest portion of this reserve is
intended to cover loan and lease losses, it is considered a general reserve
available for all credit-related purposes.
I. FEES ON STANDBY LETTERS OF CREDIT AND PARTICIPATIONS IN BANKERS ACCEPTANCES.
Fees on standby letters of credit are generally 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.
J. BUILDINGS AND EQUIPMENT. Buildings and equipment owned are carried at
original cost less accumulated depreciation. The charge for depreciation is
computed primarily on the straight-line method based on the following range of
lives: buildings--10 to 30 years; equipment--5 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.
K. 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.
L. 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.
Statement of Financial Accounting Standards (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, which is effective in 1996, was adopted January 1, 1996. No
adjustments to the carrying value of

  Notes to Consolidated Financial Statements (continued)

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.
M. 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 reported on an accrual basis.
N. TRUST SECURITY SETTLEMENT RECEIVABLES. These receivables represent other
items in the process of collection presented on behalf of trust clients.
O. PENSION BENEFITS. A noncontributory qualified pension plan covers
substantially all employees. The plan provides benefits for normal and early
retirement, deferred 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 pension 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.
P. EMPLOYEE STOCK OWNERSHIP PLAN (ESOP). A leveraged ESOP in which
substantially all employees of Northern Trust are eligible to participate was
established in 1989. 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 4.5 million
shares in the ESOP Trust, 3.15 million have been allocated as of December 31,
1995. The ESOP shares not yet allocated to individual accounts are treated as
deferred compensation and accounted for as a reduction of stockholders' equity.
Under the original terms of the ESOP, the shares were to be allocated over ten
years. In 1996, subject to Trustee approval and receipt of a ruling from the
Internal Revenue Service, the terms of the ESOP are expected to be amended.
Under the revised terms, the original maturity of the ESOP-related debt will be
effectively extended by an additional three years through a series of new loans
and the remaining unallocated shares originally scheduled to be allocated over
the next three years will be allocated over the six year period ending December
31, 2001. The Corporation also expects to make an additional contribution of
cash or shares of common stock to the ESOP in 2002.
Q. 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 estimated
contribution to this plan is charged to pension and other employee benefit
expenses.
R. INCENTIVE PLANS.
AMENDED 1992 INCENTIVE STOCK PLAN. The 1992 Incentive Stock Plan (Plan),
adopted in 1992 and amended in 1995, provides for the granting of both
nonqualified and incentive stock options. Stock appreciation rights may also be
granted in conjunction with stock options. The Plan also permits stock awards
and stock equivalents to be granted. Key employees of Northern Trust are
eligible to participate in the Plan. The Plan is administered by the
Compensation and Benefits Committee (Committee) of the Board of Directors. The
total number of shares of the Corporation's common stock authorized for
distribution under the Plan is 3,750,000.
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 are exercisable not later than ten 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 option.
Under the Plan, 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 including achievement of performance goals.

AMENDED INCENTIVE STOCK PLAN. The Amended Incentive Stock Plan, adopted in
1986, was superseded by the 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.
 
LONG-TERM INCENTIVE PLAN. Performance shares have been granted to executive
officers under the provisions of the Amended 1992 and the Amended Incentive
Stock Plans whereby the executives 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 plans is credited to performance share accounts and is
shown in stockholders' equity as common stock issuable-performance plan.
 
OTHER INCENTIVE PLANS. Various incentive plans provide for stock and cash
incentives, and bonuses to selected employees based upon the accomplishment of
various corporate net income objectives, business unit goals and individual
performance.
The above incentive plans provide for acceleration of benefits in certain
circumstances including a change of control.
 S. 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 may be subject to deductibles, co-payment provisions
and other limitations. The provisions may be changed at the discretion of
Northern Trust, which also reserves the right to terminate these benefits at
any time.
 T. 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.
 U. 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 periods' consolidated financial statements.
 
3. SECURITIES--The following tables summarize the book and fair values of
securities.

On December 31, 1995 securities with an amortized cost of $68.5 million were
transferred from the held to maturity to the available for sale category. The
net unrealized gain on these securities was $1.7 million, which was included as
a credit of $1.1 million, net of taxes, in stockholders' equity as of December
31, 1995. The securities were transferred in conjunction with the transition
provisions of accounting guidance recently issued by the Financial Accounting
Standards Board that addresses implementation issues related to SFAS No. 115.
The reclassification will increase slightly Northern Trust's flexibility in
regard to selling securities, but will not have a material impact on
asset/liability management strategy.
Income on obligations of states and political subdivisions totaled $30.7
million, $34.6 million and $38.3 million in 1995, 1994 and 1993, respectively.
Dividends received on preferred stock totaled $8.0 million, $6.4 million and
$3.8 million for 1995, 1994 and 1993, respectively.

Residential real estate loans held for sale totaled $7.6 million and $4.4

In May 1995, SFAS No. 122, "Accounting for Mortgage Servicing Rights," was
issued. This statement applies to entities that either purchase mortgage
servicing rights or originate mortgage loans and subsequently sell the mortgage
loans with servicing rights retained. In either case, the servicing rights must
be capitalized as a separate asset and must be evaluated for impairment based
on their fair value. The disclosure requirements of the statement are effective
for financial statements for fiscal years beginning after December 15, 1995.
Since Northern Trust's held for sale mortgage portfolio totaled $7.6 million as
of January 1, 1996, the impact of adopting this statement was immaterial.

There were no unfunded loan commitments and standby letters of credit issued to
borrowers whose loans were classified as nonaccrual at December 31, 1995,
versus $.1 million at December 31, 1994.
Interest income that would have been recorded on domestic nonaccrual loans in
accordance with their original terms amounted to $2.9 million in 1995, $3.1
million in 1994 and $3.5 million in 1993, compared with amounts that were
actually recorded of $.7 million, $.2 million and $1.6 million, respectively.
Interest income that would have been recorded on international nonaccrual loans
in accordance with their original terms amounted to $.1 million in 1995, 1994
and 1993, compared with amounts that were actually recorded at zero in all
three years.
Writedowns and realized losses on OREO of $.4 million in 1995, $.3 million in
1994 and $2.1 million in 1993 were charged to other operating expenses.
Northern Trust adopted SFAS Nos. 114 and 118, "Accounting by Creditors for
Impairment of a Loan," effective January 1, 1995. These statements provide
guidance as to when loans should be classified and reported as impaired and
address how the reserve for credit losses related to these loans should be
determined. Any shortfall in the estimated value of an impaired loan compared
with the recorded investment of the loan is identified as an allocated portion
of the reserve for credit losses and is one of the factors considered by
management in their overall assessment of reserve adequacy. No changes were
required to Northern Trust's accounting policies for loans, charge-offs and
interest income as a result of adopting these statements.
At December 31, 1995, nonperforming assets totaled $33.7 million. Included in
this amount were loans with a recorded investment of $27.6 million which were
also classified as impaired. Impaired loans totaling $9.2 million had no
portion of the reserve for credit losses allocated to them, while $18.4 million
had an allocated reserve of $1.0 million. For the year 1995, the total recorded
investment in impaired loans averaged $26.4 million. Total interest income
recognized on impaired loans for the year ended December 31, 1995 was $.7
million, most of which was recognized using the cash-basis method of
accounting.

7. LEASE COMMITMENTS--At December 31, 1995, Northern Trust was obligated under
a number of noncancellable operating leases for premises and equipment. Certain
leases contain rent escalation clauses, based on market indices or increases in
real estate taxes and other operating expenses and renewal option clauses
calling for increased rentals. There are no restrictions imposed by any lease
agreement regarding the payment of dividends, debt financing or Northern Trust
entering into further lease agreements. Minimum annual lease commitments as of
December 31, 1995, for all noncancellable operating leases are as follows.

The building and land utilized at the Chicago operations center has been leased
under an agreement which qualifies as a capital lease. The long-term financing
for the property was provided by the Corporation and the Bank. In the event of
sale or refinancing, the Bank will receive all proceeds except for 58% of any
proceeds in excess of the original project costs which will be paid to the
lessor.
The table below reflects the future minimum lease payments
required under this lease, net of payments received on the long-term financing,
and the present value of the net capital lease obligation at December 31, 1995
(refer to Note 8).

(a) Not redeemable prior to maturity.
(b) Under the terms of its current offering circular, the Bank has the ability
    to offer from time to time its senior bank notes in an aggregate principal
    amount of up to $1.7 billion at any one time outstanding and up to an
    additional $200 million of subordinated notes. Each senior note will mature
    from 30 days to fifteen years and each subordinated note will mature from
    five years to fifteen years, following its date of original issuance. Each
    note will mature on such date as selected by the initial purchaser and
    agreed to by the Bank.
(c) Notes are related to the contribution of 180,000 common shares to the ESOP
    trust.
(d) Notes were issued directly by the ESOP trust to finance the purchase of
    4,320,000 common shares. The Corporation unconditionally guarantees the
    payment of principal, premium, if any, and interest. The interest rate is
    subject to adjustment in the event of certain tax law changes affecting
    ESOP plans. Refer to Note 1P.
(e) Refer to Note 7.
 
LINES OF CREDIT. The Corporation currently maintains commercial paper back-up
facility lines of credit with four banks totaling $50 million. The facility was
amended in 1995 which extended the termination date to November 1999, with two
optional one-year extensions 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 1995 or
1994.
 
9. STOCKHOLDERS' EQUITY--PREFERRED STOCK. The Corporation is authorized to
issue 10,000,000 shares of preferred stock without par value. The Board of
Directors of the Corporation is authorized to fix the particular preferences,
rights, qualifications and restrictions for each series of preferred stock
issued. Summary of preferred stock outstanding is presented below.

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 1995 was 4.52%. 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.

  Notes to Consolidated Financial Statements (continued)

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" 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 1995 was 4.49%. The shares of FAPS are
redeemable at the option of Northern Trust, 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 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). Subsequently, 994,737 of the total 1,000,000
Depositary Shares were converted at the option of the holder at a conversion
price of $41.50 into 1,198,372 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-third of one-
hundredth of a share of Series A Junior Participating Preferred Stock at an
exercise price of $83.33 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 February 1994, the Corporation's common stock buyback
authorization was increased by approximately 1.3 million shares, thus allowing
the purchase after that date up to an aggregate of 4 million shares of the
common stock. The Corporation may repurchase the shares from time to time via
open market purchases, and the shares would be used for general corporate
purposes.
Analysis of changes in the number of shares of common stock outstanding
follows.

Northern Trust has state carryforwards which are available to offset future
state tax return liabilities. As of December 31, 1995, there were state net
operating loss and tax credit carryforwards of $15.4 million and $1.7 million,
respectively. The carryforwards are subject to various limitations imposed by
tax law.
 
11. NET INCOME PER COMMON SHARE COMPUTATIONS--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 assumes, in addition to the above,
the conversion of the Cumulative Convertible Preferred Stock Series E.

  Notes to Consolidated Financial Statements (continued)
 
12. 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, reduced by certain loan losses (as defined in the
applicable statute). In addition, for each of the Corporation's Federal Reserve
member banking subsidiaries, prior approval of federal banking authorities is
required if dividends declared by a subsidiary bank 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 1996 equal to their 1996
eligible net profits (as defined) plus $181.1 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.
 
13. OTHER OPERATING INCOME--The fee portion of treasury management revenues
totaled $49.6 million in 1995, $46.3 million in 1994 and $49.0 million in 1993.
Net foreign exchange revenues including trading, hedge and translation gains or
losses were $55.3 million in 1995, $36.0 million in 1994 and $32.1 million in
1993, and included foreign exchange trading profits of $55.4 million, $35.9
million and $32.4 million in 1995, 1994 and 1993, respectively.
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.
 
14. OTHER OPERATING EXPENSES--The components of other operating expenses were

Pension expense for 1993 was $7.2 million and $2.7 million for the qualified
and nonqualified plans, respectively.
Due to retirements in 1994 and 1995 a substantial number of lump-sum payments
were made from both the qualified and nonqualified plans which resulted in
settlement charges of $4.1 million in 1995 and $9.6 million in 1994. During
1993 a settlement charge of $1.7 million was recognized due to payments from
the nonqualified plan. Settlement charges are included in other operating
expenses in the consolidated statement of income.
Total assets in the "Rabbi" Trust primarily related to the nonqualified pension
plan at December 31, 1995, 1994 and 1993, amounted to $8.7 million, $9.3
million and $9.4 million, respectively.
A pension plan is also maintained for the London Branch employees. At December
31, 1995, the fair value of assets and the projected benefit obligation totaled
approximately $7.1 million and $8.1 million, respectively. At December 31,
1994, the fair value of assets and the projected benefit obligation were $6.0
million and $6.0 million, respectively. Pension expense for 1995 and 1994 was
$.6 million and $.7 million, respectively.
THRIFT INCENTIVE PLAN. Total expenses associated with the Thrift Incentive Plan
amounted to $11.3 million in 1995, $10.6 million in 1994 and $9.9 million in
1993.

Postretirement health care expense for 1993 was $4.8 million.
For measurement purposes, a 10.8 percent annual increase in the cost of covered
health care benefits was assumed for 1996. This rate is assumed to decrease
gradually to 5.6 percent 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,
1995 by approximately $7.3 million, and the aggregate of the service and
interest cost components of the 1995 net periodic postretirement benefit cost
by $.8 million. The weighted average discount rate used in determining the
accumulated postretirement benefit obligation was 7.50 percent at December 31,
1995 and 7.75 percent at December 31, 1994.
As permitted by the provisions of SFAS No. 106, the London Branch began
accruing for postretirement health care benefits effective January 1, 1995. The
transition obligation of $.4 million established at January 1, 1995 is being
amortized over a twenty year period. Postretirement benefit expense for 1995
was $.1 million and the total Accumulated Postretirement Benefit Obligation at
December 31, 1995 was $.4 million.
 
POSTEMPLOYMENT BENEFITS. In 1994, SFAS No. 112, "Employers' Accounting for
Postemployment Benefits," was adopted. The statement requires employers to
adopt accrual accounting for workers compensation, disability, severance and
other benefits provided after employment but before retirement. The accounting
under the new statement is essentially the same as Northern Trust's previous
policy.
 
16. 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 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.
 
17. 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.

48 Northern Trust Corporation
<PAGE>
 
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.

18. 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.

*These amounts include $96.2 million and $75.8 million of standby letters of
credit secured by cash deposits or participated to others as of December 31,
1995 and 1994, respectively. The weighted average maturity of standby letters
of credit was 19 months at December 31, 1995 and 1994.
 
 B. RISK MANAGEMENT INSTRUMENTS. These instruments include foreign exchange
contracts, foreign currency futures contracts, and various interest risk
management instruments.
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
50 Northern Trust Corporation
<PAGE>
 
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 and 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 and 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 $336 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.

Information about Northern Trust's strategies and objectives related to
derivative financial instruments used for asset and liability management can be
found on pages 28 and 29 and is incorporated by reference. No deferred gains or
losses related to derivative financial instruments used for asset and liability
management were included in the consolidated balance sheet at year-end 1995 or

Net revenue associated with client-related and trading interest risk management
activities totaled $2.8 million, $2.4 million, and $1.0 million during 1995,
1994, and 1993, respectively. The majority of these revenues are related to

interest rate swaps, futures contracts, and rate protection agreements, and are
reported as trading income in the consolidated statement of income. However,
these amounts 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, 1995 and 1994
subject to indemnification was $8.2 billion and $5.0 billion, respectively. All
securities borrowed were collateralized in excess of 100 percent of their
current fair value as of December 31, 1995 and 1994. 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, 1995 and 1994 was $71 million and $65 million,
respectively, based on the clearing volume for those days. Controls related to
these clearing transactions are closely monitored, however, to protect the
assets of Northern Trust.
During the second quarter of 1994, the Corporation entered into an agreement
with The Benchmark Funds, for which the Bank is investment adviser. Under the
agreement, which was essentially a written option contract, The Benchmark Funds
had the option of selling to the Corporation in June 1995, at the higher of
cost or market value, up to $111 million par value of certain floating rate
federal agency securities whose returns lagged the sharp increase in short-term
interest rates that occurred at the time the agreement was reached. The
agreement also gave the Corporation the option of purchasing the securities
from The Benchmark Funds at the higher of cost or market value. The agreement
increased net asset values and so preserved the investment flexibility
necessary to maintain competitive yields in certain money market portfolios of
The Benchmark Funds, which are used for cash management and investment by the
Bank's institutional clients. The Corporation exercised its option to purchase
the securities in June 1995 at an aggregate price of $110.6 million, equal to
the Funds' amortized cost basis in the securities. The securities, which mature
in February 1997, were recorded by the Corporation at their fair value of
$107.7 million. The fair value of the agreement recorded in other liabilities
when the Corporation entered into the 1994 agreement, was $3.5 million. This
reserve exceeded the loss realized in 1995 by $.6 million.
 
19. CONCENTRATIONS OF CREDIT RISK--The information in the section titled Loans
and Other Extensions of Credit found on pages 20 through 22 is incorporated by
reference.
 
20. 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, 1995,
securities and loans totaling $3.9 billion ($3.1 billion of U.S. Government and
agency securities, $216.8 million of obligations of states and political
subdivisions and $622.6 million of loans and other securities), were pledged.
Collateral required for these purposes totaled $2.6 billion. Deposits
maintained at the Federal Reserve Bank to meet reserve requirements averaged
$278.1 million in 1995 and $307.7 million in 1994.
 
21. INCENTIVE PLANS AND AWARDS--AMENDED 1992 INCENTIVE STOCK PLAN AND AMENDED
INCENTIVE STOCK PLAN (PLANS). In October 1995, SFAS No. 123, "Accounting for
Stock-Based Compensation," was issued. The accounting method for stock-based
compensation provided in the statement, in particular for stock options,
differs from APB Opinion No. 25, in which most of the accounting requirements
for stock-based compensation were previously contained. The measurement and
recognition provisions of the statement are

52 Northern Trust Corporation
<PAGE>
 
elective and disclosure requirements of the statement are effective in 1996. An
entity that continues to apply Opinion No. 25 will be required to provide pro
forma net income and earnings per share as if the method in SFAS No. 123 had
been used to account for stock-based compensation costs. Northern Trust is

  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, 1995
and 1994, 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, 1995. 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, 1995 and 1994, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1995 in conformity with generally accepted accounting principles.
 
                                                             Arthur Andersen LLP

Notes:-Average volume includes nonaccrual loans.
      -Interest on loans and money market assets includes fees of
       $5.1 million in 1995, $6.8 million in 1994, $13.9 million in
       1993, $11.7 million in 1992 and $5.1 million in 1991.
      -Total interest income includes adjustments on loans and
       securities (primarily obligations of states and political
       subdivisions) to a taxable equivalent basis. Such
       adjustments are based on the U.S. federal income tax rate
       (35% for 1995-1993 and 34% for 1992-1991) and State of
       Illinois income tax rate (7.18%) before giving effect to the
       deductibility of state taxes for federal income tax
       purposes. Lease financing receivable balances are reduced by
       deferred income. Total taxable equivalent interest
       adjustments amounted to $37.6 million in 1995, $33.4 million
       in 1994, $34.1 million in 1993, $32.5 million in 1992 and
       $36.0 million in 1991.
      -Yields on the portion of the securities portfolio
