NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  BASIS OF PRESENTATION  -  The consolidated financial statements include
the accounts of Northern Trust Corporation and its subsidiaries ("Northern
Trust"), all of which are wholly owned.  Significant intercompany balances and
transactions have been eliminated.  The consolidated financial statements as of
September 30, 1996 and 1995 have not been audited by independent public
accountants.  In the opinion of management, all adjustments necessary for a fair
presentation of the financial position and the results of operations for the
interim periods have been made.  All such adjustments are of a normal recurring
nature.  Certain reclassifications have been made to prior periods' consolidated
financial statements to place them on a basis comparable with the current
period's consolidated financial statements.  For a description of Northern
Trust's significant accounting principles, refer to the Notes to Consolidated
Financial Statements in the 1995 Annual Report to Stockholders.

At September 30, 1996, other domestic and international loans include $688.3
million of overnight trust-related advances in connection with next day security
settlements, compared with $810.4 million at December 31, 1995 and $946.9
million at September 30, 1995.

At September 30, 1996, nonperforming loans totaled $33.3 million. Included in
this amount were loans with a recorded investment of $29.7 million which were
also classified as impaired. 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.
Impaired loans totaling $22.5 million had no portion of the reserve for credit
losses allocated to them, while $7.2 million had an allocated reserve of $.6
million. For the third quarter of 1996, the total recorded investment in
impaired loans averaged $32.6 million. Total interest income recorded on
impaired loans for the quarter ended September 30, 1996 was $28 thousand,
recognized principally on the cash-basis method of accounting.

At September 30, 1995, nonperforming loans totaled $33.6 million and included
$27.7 million of impaired loans. $24.5 million of these impaired loans had no
reserve allocation while $3.2 million had an allocated reserve of $.4 million.
Impaired loans for the third quarter of 1995 averaged $29.0 million with $149
thousand of interest income recognized principally on the cash-basis method of
accounting.

7.  ACQUISITIONS - In August 1996, Northern Trust Corporation entered into a
definitive agreement to acquire Metroplex Bancshares, Inc., parent company of
Bent Tree National Bank in Dallas, Texas for approximately $14.6 million in
cash. Bent Tree's assets totaled $79.0 million at September 30, 1996 and net
income totaled $1.6 million for the first nine months of the year. The agreement
is subject to the approval of Metroplex shareholders and to various regulatory
approvals. Federal Reserve Board and shareholder approvals have been received
and the transaction is expected to close in the fourth quarter of 1996.

8.  NOTES PAYABLE - Under the terms of a September 12, 1996 Offering Circular,
The Northern Trust Company has the ability to offer from time to time up to $1.7
billion aggregate principal amount at any time outstanding of its senior bank
notes (less certain medium-term bank notes issued prior to April 1993 and still
outstanding), with maturities ranging from 30 days to 15 years and may offer up
to $300 million aggregate principal amount of its subordinated bank notes with
maturities ranging from 5 years to 15 years (less $100 million in subordinated
notes previously

sold). On September 24, 1996, The Northern Trust Company issued $100 million of
7.30% Subordinated Notes due 2006, priced to yield 7.38%. At September 30, 1996,
an additional $100 million of subordinated bank notes can be issued under the
terms of the Offering Circular.

ITEM 2:   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
          CONDITION AND RESULTS OF OPERATIONS


THIRD QUARTER EARNINGS HIGHLIGHTS

Net income for the third quarter totaled a record $66.5 million, an increase of
14% from the $58.1 million reported in the third quarter of 1995. Net income per
common share on a fully diluted basis increased 16% to $1.14 from $.98 in 1995.
This earnings performance produced an annualized return on average common equity
(ROE) of 18.93% versus 18.11% reported last year, and an annualized return on
average assets (ROA) of 1.26% versus 1.14% in 1995. Total revenues on a taxable
equivalent basis in the quarter increased 11% to $301.5 million with double-
digit growth in trust fees and treasury management fees, and net interest income
reached a record level, while noninterest expenses increased 9%.


NONINTEREST INCOME

Noninterest income increased 12% and totaled $194.3 million for the quarter,
accounting for 64% of total taxable equivalent revenue. Trust fees of $147.7
million increased 16% or $20.4 million over the like period of 1995, and now
represent 76% of noninterest income and 49% of total taxable equivalent revenue.
Fees generated by RCB International, Inc. (RCB), an October 31, 1995
acquisition, accounted for $6.9 million of the trust fee growth. Exclusive of
these fees, trust fees increased 11% compared to the third quarter of last year,
driven by new business, increased transaction volumes and higher market values
of trust assets administered. Trust assets under administration at September 30,
1996 increased 23% and totaled $722.7 billion compared to $585.4 billion a year
ago.

Trust fees from Corporate and Institutional Services (C&IS) increased $12.7
million to $74.1 million. Exclusive of the RCB contribution, C&IS trust fees
increased $5.8 million or 9% from the year-ago quarter. The increase in fees
reflects new business and strong revenue growth in securities lending,
investment management and retirement services. Custody fees increased 5% to
$31.0 million in the quarter. The increase in custody fees reflects net new
business partially offset by changing pricing structures that emphasize the
payment for base custody services through add-on products, such as securities
lending and foreign exchange. Securities lending fees totaled $12.2 million in
the quarter compared to $8.4 million a year ago, an increase of 45%. The growth
was driven by a 35% increase in volume and a 13% increase in the average spread
earned on the investment of the cash collateral. The investment management fee
increase was driven by new business and growth in customized products tailored
to client needs. Fees from retirement services generated by Hazlehurst &
Associates, Inc. increased primarily as a result of new business. C&IS trust
assets under administration grew 24% or $122.9 billion over last year and now
total $641.9 billion. Included in this asset base are assets

                                      10

<PAGE>
 
under the management of Northern Trust which total $77.1 billion, up 33% from a
year ago.

During the quarter, Northern Trust was named preferred provider of master trust
and domestic institutional custody services for current clients of First Chicago
NBD Corporation as it exits that business, positioning Northern Trust well to
pursue these relationships. To more effectively serve existing and new Michigan-
based master trust and institutional custody clients, Northern Trust announced
plans to open an office in Detroit, Michigan. The transition of those First
Chicago NBD clients who select Northern Trust is expected to begin in the fourth
quarter and be completed during the second quarter of 1997.

C&IS trust fees in the third quarter were 21% higher than a year ago, but $2.3
million or 3% below this year's second quarter. The sequential quarter
comparison was affected by the fact that a much higher proportion of new 1996
C&IS trust business was transitioned and began earning fees in the second
quarter than in the third quarter. The second quarter also benefited from a
number of other factors, including securities lending fees that were $2.0
million higher. Unusually strong demand for certain government and international
equity securities, and a higher spread on securities lending cash collateral,
contributed to second quarter securities lending revenues. Higher consulting
revenues in the second quarter and non-recurring items also affected the
sequential quarter comparison.

Trust fees from Personal Financial Services (PFS) increased 12% from the prior
year level of $65.9 million and totaled $73.6 million for the third quarter,
reflecting strong growth throughout Northern Trust's five-state network of PFS
offices. PFS trust fee growth resulted primarily from new business and higher
market values of the trust assets administered. During the third quarter of
1996, newly constructed Illinois facilities in Winnetka and on Chicago's South
Side opened for business, enhancing Northern Trust's service delivery to these
existing markets. At September 30, 1996, Northern Trust's network of PFS offices
totaled 55 locations throughout Illinois, Florida, California, Arizona and
Texas. Trust fees generated from the four states outside of Illinois now
comprise approximately one-half of total PFS trust fees. Total personal trust
assets under administration increased $14.4 billion from the prior year and
totaled $80.8 billion at September 30, 1996, with $47.2 billion under
management.

Security commissions and trading income totaled $5.0 million compared with $5.8
million reported in the third quarter of 1995. The decrease was due to reduced
commission revenues at Northern Futures Corporation brought about by lower trade
volume.

Other operating income totaled $41.7 million in the quarter, compared to $40.0
million in the third quarter of 1995. The principal items included in other
operating income are foreign exchange trading profits and treasury management
fees. Foreign exchange trading profits of $15.1 million were strong but fell
short of the record $16.2 million

                                      11
 

<PAGE>
 
 
realized in last year's third quarter. Foreign exchange trading profits are
impacted by the level of cross-border investment activity of Master
Trust/Custody clients and by market volatility. Northern Trust's success in
capturing custody-related foreign exchange, even in periods of lower volatility,
has enabled it to meet competitive pressures on base custody fees. The fee
component of treasury management revenues rose 12% to $13.9 million compared to
the prior year quarter. Total treasury management revenues, including both fees
and the computed value of compensating deposit balances, were $21.8 million,
representing a 14% increase from the third quarter of 1995. The compensating
deposit balances contributed to the increase in net interest income. The
improvement in treasury management revenues resulted from new business growth in
both paper- and electronic-based products.

Other operating income in the third quarter of 1996 included fees from the
renegotiation of a cash management services contract and gains recorded from the
disposition of securities received in a prior year loan restructuring. In
addition, other operating income reflects the elimination of float-related
compensation resulting from the Depository Trust Company's first quarter 1996
conversion to a same-day settlement basis for security transactions.


NET INTEREST INCOME

Net interest income for the third quarter totaled a record $98.8 million, 10%
higher than the $89.4 million reported in the third quarter of 1995. 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. When net interest income
is 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 the third quarter was $107.2 million, up 8% from the $98.9 million reported
in 1995. The increase in net interest income reflects higher levels of earning
assets, growth in noninterest-related funds, and an improvement in the net
interest margin to 2.26% from 2.21% reported in the third quarter of 1995.

Earning assets for the third quarter averaged $18.9 billion, up 6% from the
$17.8 billion average for the third quarter of 1995. The $1.1 billion growth in
average earning assets reflected a 13% or $1.2 billion increase in average
loans, partially offset by a $.4 billion decline in average security holdings.
Money market assets totaled $2.1 billion on average for the quarter, up 20% from
the like period of 1995.

The loan growth was concentrated in the domestic portfolio while international
loans declined slightly from the prior year. Residential mortgages increased 19%
to average $4.4 billion and now comprise 41% of the total average loan
portfolio. Commercial and industrial loans averaged $3.4 billion during the
third quarter of 1996 compared to $3.1

                                      12

<PAGE>
 
 
billion last year. The securities portfolio declined 6% to average $6.3 billion
primarily due to a reduction in short-term federal agency securities.

Funding for the growth in earning assets came from several sources. Total
interest-bearing deposits averaged $10.2 billion, up $785 million from the third
quarter of 1995. This growth came principally from foreign office time deposits
(up $702 million) and savings and money market deposits (up $222 million),
partially offset by a decline in savings certificates and other time deposits.
Short-term funds were also raised utilizing repurchase agreements and other
borrowings. The growth in other borrowings was concentrated primarily in higher
treasury tax and loan account balances. Noninterest-related funds increased $199
million and averaged $2.9 billion due in large part to growth in common
stockholders' equity. Common stockholders' equity increased $145 million or 12%
and averaged $1.37 billion due primarily to growth in retained earnings and the
conversion of Series E Preferred Stock in January, 1996, offset in part by the
repurchase of common stock pursuant to Northern Trust's 4 million share buyback
program. The remaining increase in noninterest-related funds was concentrated in
foreign demand and trust-related deposits.

The net interest margin increased from 2.21% in last year's third quarter to
2.26% in the current quarter, due primarily to the 13% increase in average loan
volume, the reduced holdings of low margin agency securities and the higher
level of noninterest-related funding sources.


PROVISION FOR CREDIT LOSSES

The provision for credit losses of $2.5 million was up from $2.0 million
reported in the third quarter of 1995. For a discussion of the provision and
reserve for credit losses, refer to the Asset Quality section.


NONINTEREST EXPENSES

Noninterest expenses totaled $191.3 million for the quarter, up $15.8 million or
9% from $175.5 million in the third quarter of 1995. Operating expenses of RCB
and Tanglewood Bancshares, both acquired in the second half of 1995, accounted
for approximately $6.9 million of the increase over last year. Without these
incremental costs, expense growth would have been 5%. The increase in
noninterest expenses also reflects the support necessary for higher levels of
trust new business, increased treasury management and global custody volumes,
investments in technology and continuing PFS office expansion. These increases
were partially offset by lower expenses related to pension settlement charges
for retiring officers and lower benefit costs.

Salaries and benefits, which represent 58% of total noninterest expenses,
increased to $110.9 million from $104.4 million in the year-ago quarter. Cost
savings from changes

                                      13

     in several benefit plans effective January 1, 1996 helped moderate the
     increase. The principal items contributing to the increase were merit
     increases, incentive compensation, and staff additions resulting from 1995
     acquisitions and to support Northern Trust's growing trust activities and
     office expansion. The incentive compensation expense increase reflects the
     impact of Northern Trust's higher common stock price as well as new
     business development and investment management results. Staff on a full-
     time equivalent basis at September 30, 1996 totaled 6,754, up 3% from 6,531
     at the end of 1995.

     Net occupancy expense totaled $16.3 million, up 4% from $15.6 million in
     the third quarter of 1995, due in part to acquisitions and the opening of
     new offices. The principal components of the increase were higher real
     estate taxes, building maintenance costs, and amortization and depreciation
     of leasehold improvements and buildings, offset in part by lower utility
     costs.

     Equipment expense, which includes depreciation, rental and maintenance
     costs, totaled $13.9 million, up $1.9 million or 16% from the third quarter
     of 1995. The principal components of the increase were higher levels of
     computer equipment depreciation, maintenance and rental expenses.

     Other operating expenses in the quarter totaled $50.2 million compared to
     $43.5 million last year. Other operating expenses were impacted by the
     addition of $3.2 million in professional service fees paid to RCB's network
     of investment managers, higher costs associated with legal disputes, and
     increased levels of transaction-based depository fees, software
     amortization, and amortization expense of goodwill and other intangibles.

     The components of other operating expenses were as follows:

     PROVISION FOR INCOME TAXES

     The provision for income taxes was $32.8 million for the third quarter
     compared with $27.2 million in the year-ago quarter. The higher tax
     provision in 1996 resulted from the growth in taxable earnings for both
     federal and state income tax purposes and a decline in tax-exempt income
     from the prior year. The effective tax rate was 33% for 1996 versus 32% in
     1995.


     NINE MONTHS EARNINGS HIGHLIGHTS

     Net income totaled $191.4 million for the nine months ended September 30,
     1996 compared to $160.5 million last year, an increase of 19%.  On a fully
     diluted basis, net income per common share increased 20% to $3.25.  The ROE
     for the nine month period was 18.59% versus 17.37% one year ago, while the
     ROA improved to 1.22% from 1.12% in the same period of last year.

     Noninterest income increased 15% to $577.2 million from $503.5 million in
     the like period of 1995.  Noninterest income comprised 65% of total taxable
     equivalent revenue.  Trust fees totaled $440.3 million, up 19% from $371.4
     million last year.  Security commissions and trading income totaled $17.7
     million, up $.8 million or 5% from the $16.9 million earned last year.
     Foreign exchange trading profits totaled $42.7 million, essentially
     unchanged from last year's record performance.  The fee portion of treasury
     management revenues totaled $41.4 million, up 12% from the $36.9 million
     reported in 1995.  Total treasury management revenues, which, in addition
     to fees, include the computed value of compensating deposit balances,
     increased 11% and totaled $64.3 million.  These compensating deposit
     balances also contributed to the improvement in net interest income.

     Net interest income stated on a fully taxable equivalent basis totaled
     $313.5 million, up 6% from the $294.5 million in the like period of 1995.
     The provision for credit losses increased $6.5 million to $11.5 million in
     1996.  Net loan charge-offs increased to $11.2 million from $4.8 million in
     the prior year.  Noninterest expenses were up 7% and totaled $566.9 million
     compared to $530.7 million in 1995.  Excluding $23.1 million of operating
     expenses of the businesses acquired in 1995 and the $7.8 million reduction
     in FDIC insurance premiums compared to the previous year, expense growth
     would have been 4%.


     BALANCE SHEET

     Total assets at September 30, 1996 were $21.4 billion and averaged $21.0
     billion for the first nine months, up 10% from last year's average of $19.1
     billion.  Due to increased lending activity, in addition to the July 31,
     1995 acquisition of Tanglewood Bank, loans

     and leases grew to $10.9 billion at September 30, 1996, and averaged $10.2
     billion for the first nine months. This compares with $9.8 billion in total
     loans at September 30, 1995 and $9.0 billion on average for the first nine
     months of last year.

     Driven primarily by continued strong earnings growth and the first quarter
     1996 conversion of the Series E convertible preferred stock, offset in part
     by Northern Trust's stock buyback program, common stockholders' equity
     increased 14% to average $1.35 billion for the first nine months, versus
     $1.19 billion last year. Total stockholders' equity averaged $1.47 billion
     compared with $1.36 billion in 1995.

     During the quarter, Northern Trust Corporation acquired 498,625 of its own
     shares at a total cost of $31.8 million pursuant to the 4 million share
     buyback program authorized by the Board of Directors in 1994. This brought
     the total number of shares acquired in 1996 to 1,655,142 leaving an
     additional 617,920 shares remaining to be acquired under this program. The
     Northern Trust Company successfully completed a $100 million subordinated
     bank note offering during the quarter, adding tier 2 capital at favorable
     rates. Northern Trust's risk-based capital ratios remained strong at 8.4%
     for tier 1 and 12.3% for total capital at September 30, 1996. These capital
     ratios are well above the minimum regulatory requirements of 4% for tier 1
     and 8% for total risk-based capital ratios. The leverage ratio (tier 1
     capital to third quarter average assets) of 6.3% at September 30, 1996,
     also exceeded the regulatory requirement of 3%.


     ASSET QUALITY

     Nonperforming assets consist of nonaccrual loans, restructured loans and
     other real estate owned (OREO). Nonperforming assets at September 30, 1996
     totaled $37.7 million, compared with $33.7 million at December 31, 1995 and
     $35.4 million at September 30, 1995. Nonaccrual and restructured loans and
     leases, consisting primarily of commercial loans, totaled $33.3 million, or
     .31% of total loans and leases at September 30, 1996. Included in this
     total are commercial real estate loans of $25.5 million. At December 31,
     1995 and September 30, 1995, nonaccrual and restructured loans and leases
     totaled $31.9 million and $33.6 million, respectively.

     The following Nonperforming Asset table presents the outstanding amounts of
     nonaccrual loans and leases, restructured loans and OREO. Also shown are
     loans that are delinquent 90 days or more and are still accruing interest.
     The balance in this category at any quarter end can fluctuate widely based
     on the timing of cash collections, renegotiations and renewals.

PROVISION AND RESERVE FOR CREDIT LOSSES. The provision for credit losses is the
charge against current earnings that is determined by management through a
disciplined credit review process as the amount needed to maintain a reserve
that is sufficient to absorb credit losses inherent in the loan and lease
portfolios and other credit undertakings.

The 1996 third quarter provision for credit losses was $2.5 million, compared
with $2.0 million in the third quarter of 1995. Net charge-offs totaled $2.5
million in the third quarter of 1996, versus $1.8 million last year. The reserve
for credit losses was $147.4 million or 1.35% of outstanding loans at September
30, 1996. This compares with $147.1 million or 1.49% of outstanding loans at
December 31, 1995 and $147.3 million or 1.50% of outstanding loans at September
30, 1995. The lower reserve to outstanding loans ratio at September 30, 1996 is
attributable to loan growth, a significant portion of which is in low-risk
residential mortgage lending.

The overall credit quality of the domestic portfolio has remained good as
evidenced by the low level of nonperforming loans and relatively moderate level
of net charge-offs. Management's assessment of the current U.S. economy and the
financial condition of certain clients facing financial difficulties together
with the types of loans creating portfolio growth were primary factors impacting
management's decision to maintain the reserve for credit losses at $147.4
million at September 30, 1996, essentially unchanged from December 31, 1995 and
September 30, 1995.

Management continues to monitor closely several credits, but the overall quality
of the loan portfolio remains sound and the reserve for credit losses is
adequate to cover credit-related uncertainties as they exist today. Established
credit review procedures ensure that close attention is given to commercial real
estate-related loans and other commercial loans, as well as other credit
exposures that might be adversely affected by significant increases in interest
rates or unexpected downturns in segments of the economies of the United States
or other countries.

Article I. Nature of the Plan

1.1 Establishment and Amendment of the Plan

Effective January 1, 1989, The Northern Trust Company (the "Company")
established the Northern Trust Employee Stock Ownership Plan (the "Plan"). The
Plan is hereby amended and restated effective January 1, 1989, in order to
incorporate the requirements of the Tax Reform Act of 1986 and subsequent
legislation.

1.2 Purpose of the Plan

The purpose of the Plan is to enable Members and their Beneficiaries to share in
the growth and prosperity of the Company and its Affiliates, to provide Members
with an opportunity to accumulate capital for their future economic security,
and to furnish additional security to Members who become permanently disabled.
The primary purpose of the Plan is to enable Members to acquire ownership
interests in Company Stock. Consequently, the Plan will be invested primarily in
Company Stock.

1.3 Legal Qualification

The Plan is an employee stock ownership plan under section 4975(e)(7) of the
Code and section 407(d)(6) of ERISA. It is a stock bonus plan qualified under
section 401(a) of the Code.

     organization which is a member of an affiliated service group (within the
     meaning of Code Section 414(m)) of which the Company is also a member, and
     any other entity required to be aggregated under Code Section 414(o). For

     the Participant's Beneficiary shall be the Participant's Spouse, or if
     none, as directed in the Participant's will admitted to probate, or if
     there is no will, to the Participant's estate to be distributed
<PAGE>
 
     as provided by the laws of descent of the state of Illinois in effect at
     the time of the Participant's death.

(f)  "BOARD OF DIRECTORS" OR "BOARD" means the Board of Directors of the
     Company.

(g)  "BREAK IN SERVICE" means the event described in section 3.5.

(h)  "CODE" means the Internal Revenue Code of 1986, as amended.

(i)  "COMMITTEE" means the Employee Benefits Administrative Committee of the
     Company, as constituted from time to time, which has the responsibility for

     its successors and assigns.

(k)  "COMPANY STOCK" means any qualifying employer security within the meaning
     of section 4975(e)(8) of the Code and 407(d)(1) of ERISA and regulations
     thereunder.

(l)  "COMPANY STOCK ACCOUNT" means an account of a Member that is credited with

     including amounts which the Participant elects to have contributed to the
     Participant's before-tax deposit account under The Northern Trust Company
     Thrift-Incentive Plan and any amounts contributed by or on behalf of the
     Participant to a plan designed to comply with section 125 of the Code, plus
     any amounts paid as shift differential, but exclusive of severance pay or
     any other types of compensation. Notwithstanding the preceding provisions
     of this section, for purposes of sections 2.1(u) and 7.5 and Article XV,
     "Compensation" shall have the meaning set forth in section 7.5(h)(4).
     Notwithstanding any provision of this Plan to the contrary, a Participant's
     Compensation for any calendar year prior to January 1, 1994, shall not
     exceed $200,000 (or such other amount as established by the Secretary of
     the Treasury pursuant to section 401(a)(17) of the Code).
<PAGE>
 
     In addition to other applicable limitations set forth in the Plan, and
     notwithstanding any other provision of the Plan to the contrary, effective
     January 1, 1994, the Compensation of each Participant taken into account
     under the Plan shall not exceed the annual compensation limit under section
     401(a)(17) of the Code. Effective January 1, 1994, the annual compensation
     limit under section 401(a)(17) is $150,000, as adjusted by the Commissioner
     of the Internal Revenue Service for increases in the cost of living in
     accordance with Code section 401(a)(17)(B). The cost-of-living adjustment
     in effect for a calendar year applies to any period, not exceeding 12
     months, over which Compensation is determined (the "determination period")
     beginning in that calendar year. If a determination period consists of
     fewer than 12 months, the annual compensation limit will be multiplied by a
     fraction, the numerator of which is the number of months in the
     determination period, and the denominator of which is 12.

     In determining the Compensation of a Participant for purposes of this
     limitation, the rules of Code section 414(q)(6) shall apply, except that,
     in applying such rules, the term "family" shall include only the Spouse of
     the Participant and any lineal descendants of the Participant who have not
     attained age 19 before the close of the Plan Year. If, as a result of the
     application of these rules, the adjusted dollar limitation of Code section
     401(a)(17) applicable to family members is exceeded, then the dollar
     limitation shall be prorated among the affected individuals in proportion
     to each such individual's Compensation as determined under this section
     2.1(m) before applying the limitation.

(n)  "EFFECTIVE DATE" means January 1, 1989.

(o)  "ELIGIBLE EMPLOYEE" means any Employee of the Company or a Participating
     Employer other than (1) an Employee employed by any office or branch of the
     Company located in a foreign country who, as to the United States, is a
     nonresident alien, and (2) an Employee who (A) as to the United States, is

     a retirement plan sponsored by a non-U.S. Affiliate in the country in which

     Affiliate. A person who is considered a "leased employee" (as defined
     below) of the Company or an Affiliate shall not be considered an
<PAGE>
 
     Employee for purposes of the Plan. If such a person subsequently becomes an
     Employee, and thereafter participates in the Plan, that person shall
     receive Vesting Service for employment as a leased employee except to the
     extent that the requirements of Section 414(n)(5) of the Code were
     satisfied with respect to such Employee while he or she was a leased
     employee. For purposes of the Plan a leased employee is a person who is not
     employed by the Company or an Affiliate but who performs services for the
     Company or an Affiliate pursuant to an agreement between the Company or
     Affiliate and a leasing organization, other than a person described in Code
     section 414(n)(5), if such person performed the services for a year and the

     of the Code), (3) received Compensation from the Company in excess of
     $50,000 (or such adjusted amount provided under section 414(q)(1) of the
     Code) and was in the top-paid group of Employees for such year, or (4) was
     at any time an officer of the Company and received Compensation from the
     Company in excess of 50 percent of the amount in effect under section
     415(b)(1)(A) of the Code for such Plan Year. The provisions of section
     414(q) of the Code shall apply in determining whether a Participant is a

Article III. Participation and Service

3.1 Participation

Each Eligible Employee shall become a Participant on the Entry Date on or next
following the later of the date the Eligible Employee completes one year of
Vesting Service and the date the Eligible Employee attains age 21, provided that
he or she is an Eligible Employee on such date.

3.2 Duration of Participation

An Eligible Employee who becomes a Participant shall continue to be a
Participant or Inactive Participant until he or she incurs a Break in Service,
and also shall continue to be a Member thereafter for as long as he or she is
entitled to receive any benefits hereunder. After receiving all benefits to
which he or she is entitled hereunder, he or she shall cease to be a Member
unless and until he or she thereafter becomes eligible to again become a
Participant.

3.3 Transferred or Rehired Employees

The following rules shall be applicable to Employees who (a) become Participants
because of transfer to a status qualifying for coverage under the Plan, (b)
become Inactive Participants, (c) transfer to a status not qualifying for
coverage after meeting the requirements of section 3.1 but before becoming
Participants, or (d) are rehired by the Company:

(a)  An employee becomes an Eligible Employee hereunder shall be credited with
     Vesting Service computed for all his or her employment with the Company and
     any Affiliate, before and after such transfer.

(b)  Any Participant who shall be transferred into employment as an Employee
     where he or she becomes an Inactive Participant shall continue to receive
     credit for Vesting Service under this Plan during the period he or she is
     an Inactive Participant.

(c)  Any Eligible Employee who shall meet the requirements of section 3.1 but
     shall be transferred into employment as an Employee but not as an Eligible
     Employee, before becoming a Participant, shall no longer be eligible to
     elect to have contributions made on his or her behalf hereunder. Any such
     Employee shall continue to accrue Vesting Service
<PAGE>

     during the period computed for all of the Employee's employment with the
     Company and any Affiliate.

(d)  An Employee who has a Break in Service and is subsequently reemployed by
     the Company or an Affiliate shall be considered a new Employee for purposes
     of section 3.1, unless he or she was credited with at least one year of
     Vesting Service prior to his or her Break in Service. In such case, the
     Employee shall become eligible to have contributions hereunder made on his
     or her behalf (i) before January 1, 1995, on the first day of the first
     Valuation Period in which such person is so reemployed, and (ii) from and
     after January 1, 1995, on the first day of the first payroll period
     following such reemployment.

(1)  By written notice to the Committee after his or her reemployment, an
     Employee who has not had five consecutive One-Year Breaks in Service may
     deposit with the Trustee an amount which shall be equal to the aggregate
     value of the distributions from his or her Account at the time of his or
     her previous Break in Service. All deposits must be made in cash and in a
     single lump sum. The deposits must be made within five years after the
     Employee is reemployed.

(2)  In the case of a reemployed Employee who does not have five consecutive
     One-Year Breaks in Service, the Company shall contribute to the Account of
     such Employee the amount, if any, forfeited at the time of the Employee's
     termination of service, if and only if the Employee makes the deposits
     permitted under paragraph (1) above or the Employee did not receive a
     distribution at or after the time of his or her previous termination of
     service. The Company's contribution shall be made concurrently with the
     Employee's repayment if applicable, otherwise upon the date of his or her
     reemployment.

     For each other reemployed Employee, his or her beginning balance in each of
     his or her Accounts shall be zero, and his or her previous Forfeiture, if
     any, shall not be restored.

3.4  Vesting

An Employee shall receive credit for Vesting Service for the period commencing
with the Employee's date of hire with the Company or an Affiliate and ending on
the date the Employee incurs a Break in Service. Vesting Service shall be
<PAGE>
 
calculated in accordance with reasonable and uniform standards and policies
adopted by the Company from time to time, which standards and policies shall be
consistently observed subject, however, to the following:

(a)  Vesting Service shall be computed on the following basis: (i) prior to July
     1, 1993, an Employee shall receive credit for each calendar quarter during
     which the Employee earned at least one (1) Hour of Service or otherwise
     would receive credit for Vesting Service pursuant to subsection (a) next
     above; and (ii) from and after July 1, 1993, an Employee shall receive
     credit for each calendar month during which the Employee earned at least
     one (1) Hour of Service or otherwise would receive credit for Vesting
     Service pursuant to subsection (b) below.

(b)  An Employee shall earn Vesting Service for all periods of active employment
     with the Company or an Affiliate, and for the following periods that are
     not active employment but that precede a Break in Service:

     (i)   an approved unpaid leave of absence from the Company or an Affiliate
           that is granted according to uniform and nondiscriminatory standards,
           but only if the Employee returns to work with the Company or an
           Affiliate upon the termination of such leave of absence;

     (ii)  effective August 5, 1993, an absence from work with the Company or an
           Affiliate under the Family and Medical Leave Act of 1993, but only if
           the Employee returns to work with the Company or an Affiliate upon
           the termination of such period of absence;

     (iii) a period of up to one (1) year during which an Employee is on a
           Parental Leave;

     (iv)  an absence from work with the Company or an Affiliate on account of
           military service with the armed forces of the United States, but only
           if the Employee reports for work within the period required under law
           pertaining to veteran's reemployment rights

<PAGE>
 
(c)  If an Employee incurs a Break in Service, but returns to employment with
     the Company or an Affiliate prior to incurring a One-Year Break in Service
     (as defined in Section 3.6), the period commencing on the date the Break in
     Service began and ending on the date such Employee is reemployed shall be
     counted as Vesting Service. Notwithstanding the preceding sentence, if the
     Break in Service occurs during a period of absence from active employment,
     the Employee shall not receive Vesting Service under the preceding sentence
     unless such Employee returns to employment before the first (1st)
     anniversary of the first day of such absence. If an Employee suffers a One-
     Year Break in Service and the Employee is thereafter reemployed by the
     Company or an Affiliate, such Employee's Vesting Service before such One-
     Year Break in Service shall be added to the Employee's Vesting Service
     after reemployment.

(d)  A Participant's Vesting Service shall not include periods of service with
     an entity prior to the date it became an Affiliate, except as provided in
     Schedule A hereto.

(e)  A Severance Eligible Participant shall receive credit for one (1) year of
     Vesting Service beyond that earned pursuant to the foregoing.

(f)  All periods of Vesting Service shall be aggregated; provided, however, that
     a Participant shall not receive multiple credit for Vesting Service with
     respect to any single period.

3.5 Break in Service
(a)  A "Break in Service" shall occur on earliest of:

     (i)  the date the Employee quits, is discharged, retires, or dies; or

     (ii) the first anniversary of the date the Employee separates from
          service with the Company or an Affiliate for any reason other than the
          reasons set forth in paragraph (i) above, such as vacation, holiday,
          sickness, disability, leave of absence or layoff.

(b)  The fact that an Employee separates from service with the Company or an
     Affiliate on account of military service with the armed forces of the
     United States shall not constitute a Break in Service unless the Employee
     fails to report to work within the period required under law pertaining to
     veteran's reemployment rights, in which case the Break in Service shall
<PAGE>
 
     occur on the earlier of (i) the expiration of the period by which such
     Employee was required by law to report back to work or (ii) the first
     anniversary of the d ate the Employee separated from service.

(c)  A Break in Service shall end on the date on which an Employee again
     performs an Hour of Service for the Company or an Affiliate.

(d)  The fact that an Employee who is a Participant becomes an Inactive
     Participant shall not constitute a Break in Service, but the foregoing
     rules shall continue to apply to such an Employee during the period he or
     she is an Inactive Participant.

(e)  Effective August 5, 1993, the fact that an Employee is absent from work
     under the Family and Medical Leave Act of 1993 shall not constitute a Break
     in Service if the Employee returns to work with the Company or an Affiliate
     after such period of absence.

3.6 One-Year Break in Service
(a)  The term "One-Year Break in Service" means each 12-consecutive-month period
     beginning on the date an Employee incurs a Break in Service under Section
     3.5 and ending on each anniversary of such date, provided that such
     Employee does not perform an Hour of Service for the Company or any
     Affiliate during such period.

(b)  Solely for purposes of determining whether a One-Year Break in Service has
     occurred, but not for purposes of determining Vesting Service or Credited
     Service, in the case of an Employee who is on Parental Leave, the
     Employee's Break In Service shall be deemed to occur on the second (2nd)
     anniversary of the first day of such absence, provided the Employee does
     not perform an Hour of Service for the Company or any Affiliate during such
     period of absence. The period of time between the first (1st) and second
     (2nd) anniversaries of a Parental Leave shall not be counted as a Break in
     Service, Vesting Service or Credited Service.
<PAGE>

Article IV. Employer Contributions

4.1 Contributions
Subject to section 4.2, for each Plan Year, Employer Contributions under the
Plan may be paid to the Trust in such amounts or under such a formula and at
such times as the Board may determine. Notwithstanding any provision in the Plan
or any law to the contrary, the Company shall also make Employer Contributions
to the extent necessary to satisfy the provisions of Section 4.5.

Employer Contributions for a Plan Year may be paid during the Plan Year and must
be paid no later than the due date for filing the Company's federal income tax
return for that year, including any extensions of the due date. Employer
Contributions for any Plan Year shall not be paid to the Trust in amounts that
would exceed the limitations of section 404 of the Code. Notwithstanding the
provisions of this section, no Employer Contributions in any Limitation Year
shall be in an amount that would cause (a) the Annual Additions to the Accounts
of any Participant to exceed the Maximum Permissible Amount (as defined in
section 7.5) for such Participant for that Year or (b) the sum of the defined
benefit plan fraction (as defined in section 7.5) and the defined contribution
plan fraction (as defined in section 7.5) to exceed one for such Participant for
such Limitation Year.

4.2 Medium of Payment
Employer Contributions may be paid to the Trust in cash or in shares of Company
Stock, as determined by the Board. Employer Contributions, however, shall be
paid in cash in such amounts (subject to the limitations described in section
7.5), and at such times as needed to provide the Trust with funds sufficient to
pay in full when due any principal and interest payments required by a Loan
incurred, pursuant to Committee direction, by the Trustee to finance
acquisitions of Company Stock, except to the extent such principal and interest
payments have been satisfied by the Trustee from cash dividends paid to it with
respect to Company Stock.

4.3 Allocation of Employer Contributions
All Employer Contributions for a Plan Year shall be allocated to Participants'
Accounts as provided in Article VII.
<PAGE>

4.4 No Participant Contributions
No Participant shall be required or permitted to make contributions to the Plan
or Trust.

provisions of Uniformed Services Employment and Reemployment Rights Act of 1994,
P.L. 103-353 ("USERRA"). As such, the Company and any Participating Employer
shall make special Employer Contributions as necessary to comply with USERRA and
other applicable laws.
<PAGE>

Article V. Investment of Trust Assets

5.1 Investments

Trust Assets under the Plan will be invested primarily in Company Stock.
Employer Contributions and other Trust assets may be used to acquire shares of
Company Stock from the stockholders (including former Participants) or issuer
thereof. The Trustee also may hold Trust assets in cash or invest them in
savings accounts, certificates of deposit, high grade short-term securities, any
kind of investment fund (open-end or otherwise), a common trust fund for the
investment of qualified employee benefit trusts, including any such fund
maintained by the Trustee, or in other investments desirable for the Trust.

5.2 Valuation of Company Stock

All purchases of Company Stock will be made at a price, or at prices, that do
not exceed the fair market value of such Company Stock. Except as otherwise
determined by the Trustee in accordance with ERISA, the fair market value of
Company Stock as of a given date shall be the closing price as of such date on
the New York Stock Exchange; provided, however, that before January 1, 1995, the
fair market value as of a given date shall be the median of the high and low
sale prices of Company Stock on the preceding trading day. If Company Stock is
not readily tradable on an established securities market, the determination of
the fair market value of Company Stock for all purposes of the Plan shall in all
cases be made by an independent appraiser appointed by the Committee. Any
independent appraiser appointed pursuant to this section shall meet the
requirements of section 401(a)(28)(C) of the Code.

5.3 Crediting of Stock

Company Stock purchased with the proceeds of a Loan shall be held in the
Suspense Account pending release and allocation to the Accounts of Participants
as the Loan is paid pursuant to Section 7.4. Company Stock purchased with
amounts allocated to Participants' Other Investment Accounts shall immediately
upon purchase be credited pro rata to the corresponding Company Stock Accounts.
Company Stock contributed to the Plan pursuant to Article IV shall be allocated
to the Company Stock Accounts of Participants pursuant to section 7.4.

5.4 Sales and Resales of Company Stock

The Committee may direct the Trustee to sell or resell shares of Company Stock
to any person. All such sales to any disqualified person must be made at 
<PAGE>
 
no less than the fair market value and no commission may be charged. Such sales
shall comply with section 408(e) of ERISA. All sales of Company Stock (except
Company Stock held in a Suspense Account) by the Trustee will be charged pro
rata to the Company Stock Accounts of Participants. Sales of Company Stock
pursuant to this section 5.4 may only be made to the extent not inconsistent
with section 1.3 of the Plan.
<PAGE>
 
Article VI. Exempt Loans

6.1 Requirements

(a)  The Committee may direct the Trustee to obtain Loans. Any such Loan will
     meet all requirements necessary to constitute an exempt loan within the
     meaning of section 4975(d)(3) of the Code and Treasury regulations section
     54.4975-7(b)(1)(iii) and shall be used primarily for the benefit of
     Participants, Beneficiaries, and Spouses. The proceeds of any such Loan
     shall be used, within a reasonable time after the Loan is obtained, only to
     purchase Company Stock, repay the Loan, or repay any prior Loan. Any such
     Loan shall provide for no more than a reasonable rate of interest (as
     determined under Treasury regulations section 54.4975-7(b)(7)) and must be
     without recourse against the Plan. The number of years to maturity under
     the Loan must be definitely ascertainable at all times. The only assets of
     the Plan that may be given as collateral on a Loan are shares of Company
     Stock acquired with the proceeds of the Loan and shares of Company Stock
     that were used as collateral on a prior Loan repaid with the proceeds of
     the current Loan. No person entitled to payment under a Loan shall have
     recourse against Trust Assets other than such collateral, Employer
     Contributions (other than contributions of Company Stock) that are
     available under the Plan to meet obligations under the Loan, and earnings
     attributable to such collateral and the investment of such Employer
     Contributions.

(b)  All Employer Contributions paid during the Plan Year in which a Loan is
     made (whether before or after the date the proceeds of the Loan are
     received), all Employer Contributions paid thereafter until the Loan has
     been repaid in full, and all earnings from investment of such Employer
     Contributions, shall be used to meet obligations under the Loan as such
     obligations accrue, or before such obligations accrue, unless otherwise
     designated by the Committee at the time any such Employer Contribution is
     made.

(c)  Any Company Stock acquired with the proceeds of a Loan shall be placed in a
     Suspense Account. The Company Stock in the Suspense Account must be
     released from the Suspense Account upon the payment of any portion of the
     Loan. The number of shares to be released from the Suspense Account for
     each Plan Year during the duration of the Loan shall equal the number of
     encumbered securities held immediately before release for the current Plan
     Year multiplied by a fraction. The numerator
<PAGE>
 
     of the fraction is the sum of principal and interest paid in such Plan
     Year. The denominator of the fraction is the sum of the numerator and the
     principal and interest to be paid for all future years. Such years will be
     determined without taking into account any possible extension of renewal
     periods.

(d)  If the collateral in the Suspense Account includes more than one class of
     Company Stock, the number of shares of each class to be released from the
     Suspense Account for a Plan Year must be determined by applying the same
     fraction to each class. If interest on any Loan is variable, the interest
     to be paid in future years under the Loan shall be computed by using the
     interest rate applicable as of the end of the current Plan Year.

6.2 Payments on Loans

Payments of principal and interest on any Loan during a Plan Year shall be made
by the Trustee (as directed by the Committee) only from (a) Employer
Contributions to the Trust made to meet the Plan's obligation under a Loan and
from any earnings (including dividends) attributable to such Contributions or to
Company Stock held as collateral for a Loan (received either during or prior to
the Plan Year), less payment from such contributions and earnings in prior
Years; (b) the proceeds of a subsequent Loan made to repay a prior Loan; and (c)
the proceeds of the sale of any Company Stock held as collateral for a Loan.
Such Contributions and earnings must be accounted for separately by the Plan
until the Loan is repaid.

6.3 Crediting of Released Stock

Company Stock released by reason of the payment of principal or interest on a
Loan from Employer Contributions shall, on the Anniversary Date, be allocated to
Participants as set forth in section 7.4.

6.4 Payments of Principal and Interest

(a)  The Company shall contribute to the Trust sufficient amounts to enable the
     Trust to pay principal and interest on any Loans as they are due. If the
     limitations of section 7.5 would result in Employer Contributions in an
     amount insufficient to enable the Trust to pay principal and interest on
     such Loan as it is due, then the Company may--

     (1)  make a Loan to the Trust (as described in Treasury regulation section
          54.4975-7(b)(4)(iii)), in sufficient amounts to meet such principal
          and
<PAGE>
 
          interest payments. A new Loan must also meet all requirements of an
          exempt loan within the meaning of Treasury regulation section 54.4975-
          7(b)(1)(iii) and shall be subordinated to the prior Loan. Company
          Stock released from the pledge of the prior Loan shall be pledged as
          collateral to secure the new Loan. Such Company Stock will be released
          from this new pledge and allocated to the Accounts of the Participants
          in accordance with applicable provisions of the Plan;

     (2)  purchase any Company Stock pledged as collateral in an amount
          necessary to provide the Trustee with sufficient funds to meet the
          principal and interest repayments. Any such sale by the Plan shall
          meet the requirements of section 408(e) of ERISA; or

     (3)  any combination of paragraphs (1) and (2).

(b)  Neither the Company nor any Affiliate, pursuant to this section, shall do,
     fail to do, or cause to be done any act that would result in a
     disqualification of the Plan as an employee stock ownership plan under the
     Code or ERISA.

6.5 Puts, Calls, and Other Options

Except as provided in Article X and notwithstanding any amendment to or
termination of the Plan that causes it to cease to qualify as an employee stock
ownership plan within the meaning of section 4975(e)(7) of the Code, no shares
of Company Stock acquired with the proceeds of a Loan obtained by the Trust to
purchase Company Stock may be subject to a put, call, or other option, or buy-
sell or similar arrangement while such shares are held by and when distributed
from the Plan.
<PAGE>
 
Article VII. Allocations to Participants' Accounts

7.1 Participants Entitled to Allocations

As of each Anniversary Date, a Participant is entitled to the allocations
provided in this Article VII. A Participant must be an active Eligible Employee
on the Anniversary Date in order to share in the allocations relating to that
Anniversary Date; provided that, each Participant who is on an authorized leave
of absence or whose employment terminates by reason of early or normal
retirement under the terms of the Pension Plan, or by reason of Permanent
Disability or death, or whose employment terminated in circumstances under which
he or she is a Severance Eligible Participant, will share in allocations of
Employer Contributions which have not been used to make payments on a Loan,
Company Stock released from the Suspense Account according to section 6.1(c),
and Forfeitures, for any Anniversary Date other than January 31, 1989 occurring
with respect to the Plan Year in which the leave of absence begins or employment
terminates.

7.2 Allocations to Company Stock Accounts

A separate Company Stock Account will be established for each Participant. The
Company Stock Account will be credited with (a) the Participant's allocable
share (determined under section 7.4) of Company Stock (including fractional
shares) purchased and paid for by the Trust or contributed in kind to the Trust,
(b) Forfeitures of Company Stock, and (c) any stock dividends on Company Stock
allocated to the Participant's Company Stock Accounts as of the record date
therefor. Company Stock acquired by the Trust with the proceeds of a Loan
obtained pursuant to Article VI shall be allocated to the Company Stock Accounts
of Participants according to the method set forth in section 7.4 at the time the
Company Stock is released from Suspense Accounts as provided in section 6.1(c).

7.3 Allocations to Other Investment Accounts

A separate Other Investment Account will be established for each Participant.
The Other Investments Account will be credited or debited with (a) the
Participant's allocable share (as determined under section 7.7) of the net
income or loss of the Trust, (b) Employer Contributions that have not been used
to make principal and interest payments on a Loan or to purchase Company Stock,
and (c) Forfeitures in other than Company Stock. Each Other Investment Account
will be debited for its share of any cash payments for the acquisition of
Company Stock for the benefit of Company Stock Accounts.

     that each such Participant's Compensation for January 1989 bears to the
     total of such Compensation of all such Participants (considering in both
     cases, with respect to each Participant, only Compensation not in excess of
     $16,666.66);

(b)  For the Anniversary Date on December 31, 1989, with respect to Employer
     Contributions which have not been made to make payments on a Loan, Company
     Stock released from the Suspense Account according to section 6.1(c), and
     Forfeitures incurred on or before December 31, 1989, in accordance with the
     following procedure:

     (1)  the number of shares released from the Suspense Account for the Plan
          Year shall be added to the number of shares allocated on the January
          31, 1989 Anniversary Date; and

     (2)  to preliminarily determine the number of shares to be allocated to
          each Participant entitled to share in allocations under section 3.4,
          the number determined under paragraph (1) above shall be multiplied by
          a fraction, the numerator of which is the Participant's Compensation
          for the 1989 Plan Year, and the denominator of which is the aggregate
          Compensation for the 1989 Plan Year of all Participants entitled to
          share in the allocation.

     The product so determined for each such Participant shall be decreased by
     the number of shares of Company Stock allocated to the Participant on the
     January 31, 1989 Anniversary Date; provided that, for any Participant with
     respect to whom the product of subsection (b)(2) is less than the number of
     shares allocated on the January 31, 1989 Anniversary Date, no shares
     allocated on such Anniversary Date shall be subtracted
<PAGE>
 
     from the Participant's Account. To accomplish the foregoing, (A) the
     Participants described in the foregoing proviso (the "Deficit
     Participants") will receive no allocation for the December 31, 1989
     Anniversary Date and (B) for all other Participants entitled to share in
     such allocation, the preliminary determination described in subsection
     (b)(2) shall be adjusted by subtracting from the shares otherwise allocable
     to them a number of shares equal to the shares that would have been
     subtracted from the Accounts of the Deficit Participants if the foregoing
     proviso had not applied. Such adjustment shall be accomplished pro rata
     based on the relative Compensation of affected Participants as described in
     subsection (b)(2), except that, if such adjustment would result in the
     subtraction of shares allocated to any Participant on the January 31, 1989
     Anniversary Date, then to the extent such subtraction would occur, the
     adjustment will not be made to such Participant's allocation and any
     additional adjustment shall be made pro rata (on the same basis) among the
     other affected Participants; and

(c)  For each Anniversary Date after December 31, 1989, with respect to Employer
     Contributions which have not been made to make payments on a Loan, Company
     Stock released from the Suspense Account according to section 6.1(c), and
     Forfeitures incurred since the prior Anniversary Date, in the proportion
     that each such Participant's Compensation for the Plan Year bears to the
     total Compensation of all such Participants; provided, however, that a
     special allocation may be made pursuant to section 4.5.

(d)  Effective December 12, 1994, the Company and any Participating Employer
     shall make special allocations as necessary to comply with USERRA and other
     applicable laws.

(e)  Notwithstanding subsections (b) and (c), if for any Limitation Year more
     than one-third of the Employer Contributions that are deductible as
     principal or interest payments on a Loan pursuant to the provisions of
     section 404(a)(9) of the Code would, but for the provisions of this
     subsection (e), be allocated to Highly Compensated Participants, then such
     Employer Contributions otherwise allocable to such Participants shall be
     reduced. The reduction shall be made among all Highly Compensated
     Participants in the same proportion as the amounts of such Contributions
     otherwise allocable to them and shall be made only to the minimum extent
     necessary so that no further reduction would be required to satisfy the
     conditions of section 415(c)(6) of the Code.
<PAGE>
 
The allocations made pursuant to subsections (b), (c), and (d) shall be
consistent with the provisions of sections 9.1, 9.2, 9.3, and 9.4.
Notwithstanding the preceding provisions of this section, and subject to section
7.4(d), no allocation shall be made to the Accounts of any Participant in any
Limitation Year that would cause (A) the Annual Additions of the Participant to
exceed the Maximum Permissible Amount (as defined under section 7.5) for that
year (except as permitted in section 7.5) or (B) the sum of the defined benefit
plan fraction (as defined in section 7.5) and the defined contribution plan
fraction (as defined in section 7.5) to exceed one for that Participant for that
Limitation Year.

7.5 Maximum Allocation

(a)  Notwithstanding anything to the contrary contained elsewhere in the Plan,
     but subject to section 7.4(d), for each Limitation Year, the allocations to
     the Accounts of any Participant shall be limited so that the Participant's
     Annual Additions for such Year do not exceed the Maximum Permissible Amount
     (as defined in subsection (h)(3) below).

(b)  If the foregoing limitation on allocations would be exceeded in any
     Limitation Year for any Participant as a result of the allocation of
     Forfeitures, reasonable error in estimating a Participant's Compensation,
     or under such other limited facts and circumstances as the Commissioner of
     Internal Revenue, pursuant to Treasury regulation section 1.415-6(b)(6),
     finds justify the availability of this subsection (b), the excess amount
     shall be placed, unallocated to any Participant, in a Limitation Account.
     If a Limitation Account is in existence at any time during a particular
     Limitation Year, other than the Limitation Year described in the preceding
     sentence, all amounts in the Limitation Account must be allocated to
     Participants' Accounts (subject to the limits of this section 7.5) before
     any contributions that would constitute Annual Additions may be made to the
     Plan for that Limitation Year. The excess amounts allocated pursuant to
     this subsection (c) shall be used to reduce Employer Contributions for the
     next Limitation Year (and succeeding Limitation Years, as necessary) for
     all of the Participants in the Plan. Excess amounts held in a Limitation
     Account pursuant to this section 7.5 may not be distributed to Participants
     or former Participants. The Limitation Account will not share in the
     valuation of Participants' Accounts and the allocation of earnings set
     forth in section 7.7 of the Plan, and the change in fair market value and
     allocation of earnings attributable to the
<PAGE>

     Limitation Account shall be allocated to the remaining accounts hereunder
     as set forth in this section 7.5.

(c)  Upon termination of the Plan, any amounts in a Limitation Account at the
     time of such termination shall revert to the Company or Participating
     Employer that employs the Employees to whom such amounts are attributable.

(d)  If any Participant under the Plan is also a Participant in a defined
     benefit plan (as defined in section 415(k) of the Code) maintained by the
     Company or an Affiliate, the sum of the defined benefit plan fraction (as
     defined below) and the defined contribution plan fraction (as defined
     below) for any Limitation Year with respect to such Participant shall not
     exceed one. If a Participant is otherwise entitled to receive an allocation
     under this Plan and accrue a benefit under a defined benefit plan
     maintained by the Company or an Affiliate, and the combination thereof
     would cause the limitations of this section to be exceeded, the allocation
     under this Plan will only be reduced if the accrual under such defined
     benefit plan is not decreased as necessary to cause such limitations not to
     be exceeded.

(e)  If a Participant is entitled to receive an allocation under this Plan and
     any Related Plan and, in the absence of the limitations contained in this
     section, the Company would contribute or allocate to the Accounts of that
     Participant an amount for a Limitation Year that would cause the Annual
     Additions to the Accounts of the Participant to exceed the annual Maximum
     Permissible Amount for such Year, then the contributions and allocations
     made with respect to the Participant under this Plan will only be reduced
     if the contributions or allocations to the Participant's accounts under the
     Related Plan are not decreased to the extent necessary so that the
     Participant's Annual Additions do not exceed the Maximum Permissible
     Amount.

(f)  Any reduction in the contributions and allocations under this Plan made
     with respect to a Participant's Accounts required pursuant to this section
     and section 415 of the Code shall be effected, to the minimum extent
     necessary, by reducing the Employer Contributions that would have been made
     by the Company for the applicable Plan Year with respect to such
     Participant.
<PAGE>
 
(g)  The provisions of this section shall be interpreted by the Committee, in
     the administration of the Plan, to reduce contributions and allocations (as
     required by this section) only to the minimum extent necessary to reflect
     the requirements of section 415 of the Code, as amended and in force from
     time to time, and Treasury regulations promulgated pursuant to that
     section, which are incorporated by reference herein.

(h)  For purposes of this section 7.5--

     (1)  The "defined benefit plan fraction" for any Limitation Year for a
          Participant means a fraction, the numerator of which is the projected
          annual benefit of the Participant under all defined benefit plans
          maintained by the Company or an Affiliate, determined as of the close
          of the Limitation Year, and the denominator of which is the lesser of
          (A) the product of 1.25, and the dollar limitation in effect under
          section 415(b)(1)(A) of the Code for such year or (B) the product of
          1.4 and the amount which may be taken into account under section
          415(b)(1)(B) of the Code with respect to such Participant for such
          Year.

     (2)  The "defined contribution plan fraction" for any Limitation Year for
          any Participant means a fraction, the numerator of which is the sum of
          the Annual Additions to the Participant's Account under the Plan and
          to the Participant's accounts under all defined contribution plans
          maintained by the Company or an Affiliate as of the close of the
          Limitation Year, and the denominator of which is the sum of the lesser
          of the following amounts determined for such Year and for each prior
          year of Vesting Service with the Company or an Affiliate (A) the
          product of 1.25 and the dollar limitation in effect under section
          415(c)(1)(A) of the Code for such Year (determined without regard to
          section 415(c)(6) of the Code) and (B) the product of 1.4 and the
          amount which may be taken into account under section 415(c)(1)(B) of
          the Code with respect to such Participant for such Year.

     (3)  "Maximum Permissible Amount" shall mean:

          (A)  the lesser of--

               (i)  $30,000 (or, if greater, one-fourth of the dollar limitation
                    in effect pursuant to section 415(b)(1)(A) of the Code); or
<PAGE>
 
               (ii) 25 percent of a Participant's Compensation (as defined in
                    paragraph (4) hereof).

          (B)  Notwithstanding the provisions of paragraph (A), if no more than
               one-third of the Employer Contributions for the Limitation Year
               ending December 31, 1989 are allocated to Highly Compensated
               Participants, then the Maximum Permissible Amount for that
               Limitation Year shall mean the lesser of--

               (i)  25 percent of a Participant's Compensation; or

               (ii) the sum of (a) $30,000 (or, if greater, one-fourth of the
                    dollar limitation in effect under section 415(b)(1)(A) of
                    the Code) and (b) the lesser of the amount determined under
                    clause (a) above or the amount of employer securities (as
                    defined in sections 4975(e)(8) and 409(1) of the Code)
                    contributed to the Plan or purchased with cash contributions
                    to the Plan.

          (C)  If no more than one-third of the Employer Contributions for a
               Limitation Year that are deductible as principal or interest
               payments on a Loan pursuant to the provisions of section
               404(a)(9) of the Code are allocated to Highly Compensated
               Participants, then the limitations imposed by paragraph (A) or
               (B), whichever is applicable, shall not apply to--

               (i)  Forfeitures of Company Stock if the Company Stock was
                    acquired with the proceeds of a Loan; or

               (ii) Employer Contributions that are deductible as interest
                    payments on a Loan under section 404(a)(9)(B) of the Code
                    and charged against a Participant's Account.

     (4)  For purposes of this section and sections 2.1(u) and Article XV,
          "Compensation" shall mean wages, salaries, fees for professional
          services, and other amounts received for personal services actually
          rendered in the course of employment with the Company or an Affiliate
          (including, but not limited to, commissions paid salesmen,
          compensation for services on the basis of a percentage of profits,
          tips, and bonuses); shall include all compensation actually paid or
          made
<PAGE>
 
          available to a Participant for an entire Limitation Year; and shall
          not include any other items or amounts paid to or for the benefit of a
          Participant.

(i)  To the extent permitted, the limitations set forth in this section 7.5
     shall be adjusted in connection with contributions made pursuant to section
     7.4(d).

7.6 Vesting

(a)  Each Participant shall have a vested interest in the adjusted balance of
     his or her Company Stock and Other Investments Accounts in accordance with
     the vesting schedule set forth in 2.1(vv).

(b)  On reaching the Normal Retirement Date, a Participant shall be 100 percent
     vested in the adjusted balance of his or her Company Stock and Other
     Investments Accounts if such Participant is an Employee on his or her
     Normal Retirement Date.

(c)  In the event a Participant dies or incurs a Permanent Disability within the
     meaning of section 9.3, the Participant shall be 100 percent vested in the
     adjusted balance of the Company Stock and Other Investments Accounts as of
     the date of the Participant's death or Permanent Disability if such
     Participant is an Employee on the date he or she dies or becomes disabled.

(d)  In the event the Plan is terminated or upon the complete discontinuance of
     Employer Contributions to the Plan, each Participant shall be 100 percent
     vested in the adjusted balance of his or her Company Stock and Other
     Investments Accounts.

7.7 Net Income or Loss of the Trust

(a)  DIVIDENDS ON COMPANY STOCK. Any stock dividends received in respect of
     Company Stock allocated to a Participant's Company Stock Account as of the
     record date therefor shall be credited to the Participant's Company Stock
     Account on the Valuation Date coincident with or succeeding the Trustee's
     receipt of such dividends. Any stock dividends received in respect of
     Company Stock held in the Suspense Account as of the record date shall be
     allocated to such Account and released pursuant to Section 6.1(c). Any cash
     dividends received on Company Stock held in the Suspense Account pursuant
     to section 6.1(c), or any cash or stock
<PAGE>
 
     dividends received on Company Stock that has been forfeited pursuant to
     section 9.4(b) but not yet reallocated pursuant to section 7.4(c), as of
     the record date, may be used to meet obligations under the Loan, the
     proceeds of which were used to acquire such Company Stock. Any dividends
     described in the preceding sentence shall, to the extent such amounts are
     not used to pay principal or interest on a Loan, be considered net income
     for the Trust for the Plan Year.

(b)  Other Income or Loss. The net income or loss of the Trust shall be
     determined as of each Valuation Date. Each Participant's share of the net
     income or loss will be allocated to the Participant's Other Investments
     Accounts in the ratio that the balance of all his or her Accounts on the
     last Valuation Date, based on the fair market value thereof (reduced by the
     amount of any distribution from such Accounts, including a distribution or
     transfer pursuant to section 7.9, other than a distribution made in the
     calendar quarter that the Participant ceases being an Employee), bears to
     the sum of such balances for all Participants as of that date. The net
     income or loss of the Trust includes the increase or decrease in the fair
     market value of Trust Assets (other than Company Stock), interest income,
     dividends, and other income or loss attributable to Trust Assets (other
     than Company Stock, except as provided in subsection (a) above) since the
     last Valuation Date. Net income or loss shall not include Employer
     Contributions or Forfeitures. Any proceeds of sales of unallocated Company
     Stock shall, to the extent such amounts are not used to pay principal or
     interest on a Loan, be considered net income for the Trust. Net income or
     loss attributable to any Limitation Account established under section 7.5
     shall be allocated to the Other Investments Accounts of Participants in
     accordance with the ratio described in the second sentence of this
     subsection (b), and the Limitation Account shall not share in the
     allocation of net income or loss of the Trust under this section.

7.8 Accounting for Allocations

The Committee shall adopt accounting procedures for the purpose of making the
allocations, valuations, and adjustments to Participants' Accounts provided for
in this section. Except as provided in Treasury regulation section 54.4975-11,
Company Stock acquired by the Plan shall be accounted for as provided under
Treasury regulation section 1.402(a)-l(b)(2)(ii); allocations of Company Stock
shall be made separately for each class of stock; and the Committee shall
maintain adequate records of the cost basis of all shares of Company Stock
<PAGE>
 
allocated to each Participant's Company Stock Accounts. From time to time, the
Committee may modify the accounting procedures for the purpose of achieving
equitable and nondiscriminatory allocations among the Accounts of Participants
in accordance with the general concepts of the Plan and the provisions of this
section. Annual valuations of Trust Assets shall be made at fair market value.

7.9 Diversification of Investments

(a) Prior to the date that section 2.1(ll)(2) becomes operative, a Participant
    who is a Qualified Participant pursuant to section 2.1(ll)(1) may elect, on
    or before the March 15 next succeeding the end of each Plan Year in the
    Qualified Election Period described in section 2.1(kk)(1) to have the
    Trustee dispose of a specified whole number of shares of Company Stock not
    in excess of the Participant's "Applicable Amount" and transfer the proceeds
    thereof to the Northern Trust Company Thrift Incentive Plan. Participant
    elections shall be in such written, electronic, or other form as the
    Committee shall determine. A Qualified Participant's Applicable Amount for a
    Plan Year in the Qualified Election Period shall equal 25 percent of (1) the
    total number of shares of Company Stock ever acquired by or contributed to
    the Plan and allocated to the Participant's Accounts in the Plan as of the
    end of such Plan Year less (2) the number of shares to which a prior
    election under this subsection applied; provided that, if with respect to a
    Qualified Participant, such difference is not a whole number of shares of
    Company Stock, it shall be rounded to the nearest whole number of shares. In
    the case of the last year of a Qualified Election Period, the preceding
    sentence shall be applied by substituting "50 percent" for "25 percent."

(b) On and after the date that section 2.1(ll)(2) becomes operative, a
    Participant who is a Qualified Participant pursuant to section 2.1(ll)(2)
    may elect, within 90 days after the close of each Plan Year in the Qualified
    Election Period described in section 2.1(kk)(2) to receive a distribution of
    the Applicable Amount (calculated in the manner described in subsection (a)
    but considering only elections, if any, made during such Qualified Election
    Period). Participant elections shall be in such written, electronic, or
    other form as the Committee shall determine. The Committee shall direct the
    Trustee to distribute the portion of the Participant's Accounts that is
    covered by the election described in this subsection (b) within 90 days
    after the last day of the period during
<PAGE>
 
     which the election can be made. Such a distribution shall not be subject to
     the requirements of section 10.2 of the Plan.

(c)  The provisions of this section shall apply notwithstanding any other
     provisions of the Plan.

(d)  If the Committee receives a Qualified Participant's election pursuant to
     subsection (a) or (b), it shall direct the Trustee (1) to sell the required
     number of shares of Company Stock (and, if the Committee desires, the
     manner in which such sale should be accomplished) as of the March 31 next
     succeeding the end of the Plan Year with respect to which the election is
     made and (2) to transfer to the Northern Trust Company Thrift Incentive
     Plan or distribute to the Qualified Participant, as the case may be, an
     amount of cash equal to the proceeds of the sale of the subject shares. Any
     such transfer shall be made as of the next succeeding April 1, and any such
     distribution shall be made within 90 days after the last day of the period
     during which the election can be made. Notwithstanding any provision of the
     Plan to the contrary, if the Trustee is unable to sell the required shares
     as aforesaid in a timely manner, the Company shall buy such shares. If such
     shares are sold to the Company or an Affiliate, the price paid therefor
     shall be the greater of the fair market value of such shares as of March 31
     or the fair market value of such shares on the date the sale actually
     occurs; provided that, any amount the Plan receives in excess of the fair
     market value as of March 31 shall be considered earnings of the Plan and
     shall be allocated as provided in section 7.7(b).

(e)  Notwithstanding the foregoing, a Qualified Participant shall not be
     entitled to make an election hereunder for a Plan Year within a Qualified
     Election Period if the fair market value of the total number of shares of
     Company Stock ever acquired by or contributed to the Plan and allocated to
     the Participant's Accounts in the Plan as of the last day of such Plan Year
     is less than $500.

Article VIII. Voting and Tender of Company Stock

8.1 Procedures for Voting

Each Member (or, in the event of the Member's death, the Member's Beneficiary)
shall have the right to direct the Trustee as to the manner in which whole and
partial shares of Company Stock allocated to the Member's Account as of the
record date are to be voted on each matter brought before an annual or special
stockholders' meeting. Before each such meeting of stockholders, the Trustee
shall furnish to each Member (or Beneficiary) a copy of the proxy solicitation
material, together with a form requesting directions on how such shares of
Company Stock allocated to such Member's Account shall be voted on each such
matter. Upon timely receipt of such directions, the Trustee shall on each such
matter vote as directed the number of shares (including fractional shares) of
Company Stock allocated to such Member's Account, and the Trustee shall have no
discretion in such matter. The directions received by the Trustee from Members
shall be held by the Trustee in confidence and shall not be divulged or released
to any person, including officers or employees of the Company or any Affiliate.
The Trustee shall vote allocated shares for which it has not received direction
and unallocated shares of Company Stock in the same proportion as directed
shares are voted, and shall have no discretion in such matter except as
otherwise provided in accordance with ERISA.

8.2 Tender Offer

If a tender or exchange offer is commenced for Company Stock--

(a)  The Trustee shall distribute in a timely manner to each Member (or
     Beneficiary) such information as is distributed to holders of the Company
     Stock in connection with the tender or exchange offer.

(b)  All Company Stock held by the Trustee in Accounts shall be tendered or not
     tendered by the Trustee in accordance with directions it receives from
     Members (or Beneficiaries). Each Member (or Beneficiary) shall be entitled
     to direct the Trustee with respect to the tender of such Company Stock
     allocated to the Member's Account. The instructions received by the Trustee
     from Members (or Beneficiaries) shall be held by the Trustee in confidence
     and shall not be divulged or released to any person, including officers or
     employees of the Company or any Affiliate.
<PAGE>
 
(c)  The Trustee shall not tender Company Stock allocated to Accounts with
     respect to which directions by Members (or Beneficiaries) are not received
     or Company Stock held by the Trustee that is not allocated to Accounts
     except as otherwise provided in accordance with ERISA.
<PAGE>
 
Article IX. Benefits

9.1 Payments on Retirement

A Member who attains his or her Normal Retirement Date and continues to be an
Employee shall continue to share in the allocation of Employer Contributions and
Forfeitures under the Plan. Upon the retirement of a Member on or after his or
her Normal Retirement Date, the Committee shall notify the Trustee in writing of
the Member's retirement and shall direct the Trustee to make payment of the
adjusted balance of the Member's Accounts as of the Valuation Date coinciding
with or immediately preceding the date a distribution is made to the Member,
unless the Member agrees to a later date in a method provided in the Plan.
Notwithstanding the foregoing, if any such Member retires after December 31,
1989 and receives a distribution of the Member's Accounts before the Anniversary
Date next following his or her retirement, he or she shall be entitled to share
in the allocation of Employer Contributions which have not been used to make
payments on a Loan, Company Stock released from the Suspense Account according
to section 6.1(c), and Forfeitures, occurring on such Anniversary Date.

9.2 Payments on Death

(a)  Upon the death of a Member, the Committee shall promptly notify the Trustee
     in writing of the Member's death and the name of the Member's Beneficiary
     (or Spouse if subsection (c) is applicable) and shall direct the Trustee to
     make payment of the adjusted balances of the Member's Accounts (or the
     Vested Portion thereof if section 7.6(c) is not applicable) as of the
     Valuation Date coinciding with or immediately preceding the date a
     distribution is made to the Member's Beneficiary, in a method provided in
     the Plan. Notwithstanding the foregoing, if such Member dies after December
     31, 1989 and the distribution of the Accounts of such Member is made before
     the Anniversary Date next following his or her death, his or her
     Beneficiary or Spouse, as the case may be, shall be entitled to share in
     the allocation of Employer Contributions which have not been used to make
     payments on a Loan, Company Stock released from the Suspense Account
     according to section 6.1(c), and Forfeitures, occurring on such Anniversary
     Date.

(b)  Each unmarried Member and each married Member whose surviving Spouse has
     consented to an alternate Beneficiary or an alternate method of payment as
     provided in subsection (c) shall have the right to designate, by giving a
     written designation to the Committee, a person or entity as Beneficiary to
     receive the death benefit provided under this section. Successive
     designations may be made, and the last designation received by the
     Committee prior to the death of the Member shall be effective and shall
     revoke all prior designations.
<PAGE>
 
     If a designated Beneficiary shall die before the Member, his or her
     interest shall terminate, and, unless otherwise provided in the Member's
     designation, if the designation included more than one Beneficiary, such
     interest shall be paid in equal shares to those Beneficiaries, if any, who
     survive the Member. A Member to whom this subsection applies shall have the
     right to designate different Beneficiaries to receive the adjusted balance
     in the Member's various Accounts under the Plan.

(c)  The Beneficiary of each Member who is married shall be the surviving Spouse
     of such Member and the death benefits of any Member who is married shall be
     paid in full to his or her surviving Spouse in a single payment.
     Notwithstanding the preceding sentence, the death benefits provided
     pursuant to subsection (a) shall be distributed to any other Beneficiary
     designated by a married Member as provided in subsection (b) of this
     section if the Member's surviving Spouse consented to such designation,
     prior to the date of the Member's death, in writing. Such a consent must
     acknowledge the effect of the election and designation and the identity of
     any nonsurviving Spouse Beneficiary, including any class of Beneficiaries
     or contingent Beneficiaries, and must be witnessed by a representative of
     the Plan or a notary public. Consent of a Member's surviving Spouse shall
     not be required if the Member establishes to the satisfaction of the
     Committee that consent may not be obtained because there is no surviving
     Spouse or the surviving Spouse cannot be located, or because of such other
     circumstances as the Secretary of the Treasury may prescribe by
     regulations. The Member may not subsequently change the designation of the
     Beneficiary unless his or her surviving Spouse consents to the new
     designation in accordance with the requirements set forth in the preceding
     sentence, or unless the surviving Spouse's consent permits the Member to
     change the designation of his or her Beneficiary without the Spouse's
     further consent. A surviving Spouse's consent shall be irrevocable. Any
     consent by a surviving Spouse, or establishment that the consent of the
     surviving Spouse may not be obtained, shall be effective only with respect
     to that surviving Spouse.



9.3 Payments on Permanent Disability

Upon the termination of a Member's employment with the Company by reason of a
Permanent Disability, the Committee shall notify the Trustee in writing of the
Member's Permanent Disability termination and shall direct the Trustee to make
payment of the adjusted balances of the Member's Accounts as of the Valuation
Date coinciding with or immediately preceding the date a distribution is made to
the
<PAGE>
 
Member. Notwithstanding the foregoing, if such termination occurs after December
31, 1989 and such Member receives a distribution of the Member's Accounts before
the Anniversary Date next following the Member's termination, he or she shall be
entitled to share in the allocation of Employer Contributions which have not
been used to make payments on a Loan, Company Stock released from the Suspense
Account according to section 6.1(c), and Forfeitures, occurring on such
Anniversary Date.

9.4 Payments on Termination for Other Reasons

(a)  GENERAL. Upon the termination of a Member's employment with the Company for
     any reason other than retirement on or after the Member's Normal Retirement
     Date, death, or Permanent Disability, the Committee shall notify the
     Trustee in writing of the termination and shall direct the Trustee to make
     payment of the Vested Portion of the adjusted balances of the Member's
     Accounts as of the Valuation Date coinciding with or next preceding the
     date a distribution is made to the Member. Notwithstanding the foregoing,
     if such termination occurs after December 31, 1989 and under circumstances
     entitling the Member to early retirement benefits under the Pension Plan
     and he or she receives a distribution of the Member's Accounts before the
     Anniversary Date following the Member's termination, he or she shall be
     entitled to share in the allocation of Employer Contributions which have
     not been used to make payments on a Loan, Company Stock released from the
     Suspense Account according to section 6.1(c), and Forfeitures, occurring on
     such Anniversary Date. The Vested Portion of a Member's Accounts shall be
     determined in accordance with section 7.6 of the Plan.

(b)  FORFEITURE. The Unvested Portion of the adjusted balance of the Accounts of
     a Member who terminates employment with the Company under this section
     shall be forfeited as of the first Valuation Date following the date the
     Member terminates employment with the Company and all Affiliates. The
     amount forfeited shall be the entire Unvested Portion. If a Member's
     Company Stock Account includes more than one class of Company Stock, the
     Forfeiture will consist of the same proportion of each class of stock.

(c)  REINSTATEMENT. If a Member is reemployed by the Company or a Participating
     Employer after incurring a Forfeiture, the Member shall be entitled to make
     repayment to the Plan of the aggregate amount distributed to him, at any
     time before the earlier of (1) five years after the Member is reemployed
     and (2) the end of a Break in Service of five consecutive years incurred by
     the Member. Upon making repayment in a single cash sum of the fair market
     value (at the time of distribution) of the aggregate amount
<PAGE>
 
     distributed to him, the amount repaid shall be credited to the Member's
     Account and invested by the Trustee in a cash equivalent short term
     investment fund. The amount which was forfeited (also based on the fair
     market value at the time of distribution) shall be reinstated to the
     Member's Account. The amount required to restore such Member's Account
     shall be made up from Forfeitures and, to the extent necessary, Employer
     Contributions prior to their allocation pursuant to section 7.4.

9.5 Deemed Cashout

If a Member has no vested interest in his Account balance when his or her
employment with the Company and all Affiliates terminates, such Member will be
treated as having received a Deemed Cashout of the Member's Account balance as
of the last day of the Plan Year in which the Member's employment terminated and
the Member's Account balance will be treated as a Forfeiture on such date.
"Deemed Cashout" means a distribution of zero dollars representing the Member's
entire Account balance. If the Member is reemployed with the Company or any
Affiliate before such Member has incurred five (5) consecutive One-Year Breaks
in Service, the amount of the prior Forfeiture will be restored as the Member's
Account balance.


9.6 Property Distributed

Any distribution pursuant to section 9.1, 9.2, 9.3, or 9.4, from a Member's
Company Stock Account, shall be made in whole shares of Company Stock, and the
value of partial shares of Company Stock shall be paid in cash. Distribution
from a Member's Other Investments Account shall be made in cash unless the
Member requests a distribution in stock of the whole shares purchasable with
such balance and the balance attributable to fractional shares in the Member's
Company Stock Account, in which case the Trustee shall acquire the necessary
shares for distribution. If cash is to be distributed in connection with
fractional shares, the Trustee shall sell such shares as of the Valuation Date
with respect to which the distribution is being made and distribute the proceeds
of sale to the affected Member. Any such sale shall be subject to the last two
sentences of section 7.9(d).

9.7 Methods of Payment

(a)  Whenever the Committee shall direct the Trustee to make payment to a Member
     upon termination of a Member's employment on or after the Member's Normal
     Retirement Date, the Committee shall direct the Trustee to pay the adjusted
     balances of the Member's Accounts to or for the benefit of the Member in a
     single sum distribution. Whenever the Committee shall direct the Trustee to
     make payment to a Member, the Member's Spouse, or other Beneficiary upon
     termination of a Member's employment for any other
<PAGE>
 
     reason, the Committee shall direct the Trustee to pay the Vested Portion of
     the adjusted balances of the Member's Accounts, if any, to or for the
     benefit of the Member, the Member's Spouse, or the Member's Beneficiary, in
     a single payment distribution.

(b)  Payment under this section shall be made no more than 60 days after the
     Valuation Date coincident with or following the date the Member ceases
     being an Employee provided that (1) for purposes of the foregoing, any
     Valuation Date occurring before December 31, 1989 shall be treated as
     occurring on December 31, 1989, (2) any Member or Beneficiary or Spouse
     described in section 9.1, 9.2, or 9.3, or who would be entitled to an
     allocation at the next Anniversary Date under section 9.4, may elect to
     defer distribution to such Anniversary Date, and (3) if the Member's
     Accounts exceed $3,500, distribution shall not be made to the Member at any
     time prior to the Member's Normal Retirement Date or death without the
     Member's written consent. A Member described in paragraph (3) may elect to
     receive distribution of the Member's Accounts as of any Valuation Date
     following the Valuation Date next succeeding the Member's termination by
     filing prescribed materials with the Trustee on or before such reasonable
     deadline as established by the Trustee.

     If a distribution is one to which sections 401(a)(11) and 417 of the Code
     do not apply, such distribution may commence less than thirty (30) days
     after the notice required under section 1.411(a)-11(c) of the Income Tax
     Regulations is given, provided that:

          (i) the Committee clearly informs the Member that the Member has a
          right to a period of at least thirty (30) days after receiving the
          notice to consider the decision of whether to elect a distribution,
          and

          (ii) the Member, after receiving the notice, affirmatively elects a
          distribution.

(c)  Notwithstanding the provisions of subsection (b) above, distribution of
     each Member's Accounts must commence not later than 60 days after the last
     day of the Plan Year in which the last of the following events occurs:

     (1) the date on which the Member reaches his or her Normal Retirement Date;

     (2) the tenth anniversary of the date on which the Member commenced
         participation in the Plan; or
<PAGE>
 
     (3)  the date on which the Member's employment with the Company and all
          Affiliates terminates.

(d)  Notwithstanding anything to the contrary contained elsewhere in the Plan--

     (1) A Member's benefits under the Plan will--

          (A)  be distributed to him or her not later than the Required
               Distribution Date (as defined in paragraph (3)), or

          (B)  be distributed commencing not later than the Required
               Distribution Date in accordance with regulations prescribed by
               the Secretary of the Treasury over a period not extending beyond
               the life expectancy of the Member or the life expectancy of the
               Member and the Member's Beneficiary.

     (2) Payments on death--

          (A)  If the Member dies after distribution has commenced pursuant to
               paragraph (1)(B) but before the Member's entire interest in the
               Plan has been distributed to him, then the remaining portion of
               that interest will be distributed at least as rapidly as under
               the method of distribution being used under paragraph (1)(B) at
               the date of the Member's death.

          (B)  If the Member dies before distribution has commenced pursuant to
               paragraph (1)(B), then, except as provided in paragraphs (2)(C)
               and (2)(D), the Member's entire interest in the Plan will be
               distributed within five years after the Member's death.

          (C)  Notwithstanding the provisions of paragraph (2)(B), if the Member
               dies before distribution has commenced pursuant to paragraph
               (1)(B) and if any portion of the Member's interest in the Plan is
               payable (i) to or for the benefit of a Beneficiary, (ii) in
               accordance with regulations prescribed by the Secretary of the
               Treasury over a period not extending beyond the life expectancy
               of the Beneficiary, and (iii) beginning not later than one year
               after the date of the Member's death or such later date as the
               Secretary of the Treasury may prescribe by regulations, then the
               portion referred to in this
<PAGE>
 
               paragraph (2)(C) shall be treated as distributed on the date on
               which such distribution begins.

          (D)  Notwithstanding the provisions of paragraphs (2)(B) and (2)(C),
               if the Beneficiary referred to in paragraph (2)(C) is the Spouse
               of the Member, then--

               (i)  the date on which the distributions are required to begin
                    under paragraph (2)(C)(iii) of this section shall not be
                    earlier than the date on which the Member would have
                    attained age 70-1/2, and

               (ii) if the Spouse dies before the distributions to that Spouse
                    begin, then this paragraph (2)(D) shall be applied as if the
                    surviving Spouse were the Member.

     (3)  For purposes of subsection (d)(1), the Required Distribution Date
          means April 1 of the calendar year following the calendar year in
          which the Member attains age 70-1/2; provided, however, that in the
          case of a Member who attained age 70-1/2 before January 1, 1988 such
          Member's Required Distribution Date shall be April 1 following the
          calendar year in which occurs the later of (A) the Member's attainment
          of age seventy and one-half (70-1/2), or (B) the Member's termination
          of employment, unless such Member is a Five-Percent Owner (as defined
          in Section 416(i) of the Code) of the Company at any time during the
          Plan Year ending with or within the calendar year in which such owner
          attains age sixty-six and one-half (66-1/2) or any subsequent year, in
          which case clause (B) shall not apply.

     (4)  For purposes of subsection (d), once distribution has commenced
          hereunder, the life expectancy of a Member and the Member's Spouse may
          not be redetermined.

     (5)  A Member may not elect a form of distribution pursuant to paragraph
          (1) providing payments to a Beneficiary who is other than the Member's
          Spouse unless the actuarial value of the payments expected to be paid
          to the Member is more than 50 percent of the actuarial value of the
          total payments expected to be paid under such form of distribution.

9.8  Direct Rollover of Eligible Rollover Distributions
<PAGE>
 
(a)  This section 9.8 applies to distributions made on or after January 1, 1993.
     Notwithstanding any provision of the Plan to the contrary that would
     otherwise limit a distributee's election under this section, a distributee
     may elect, at the time and in the manner prescribed by the Committee, to
     have any portion of an eligible rollover distribution paid directly to an
     eligible retirement plan specified by the distributee in a direct rollover.
     Any portion of an eligible rollover distribution that is not paid directly
     to an eligible retirement plan in a direct rollover may be subject to 20%
     Federal income tax withholding.

(b)  Definitions.

     (1) Eligible Rollover Distribution. An eligible rollover distribution is
         any distribution of all or any portion of the balance to the credit of
         the distributee, except that an eligible rollover distribution does not
         include: any distribution that is one of a series of substantially
         equal periodic payments (not less frequently than annually) made for
         the life (or life expectancy) of the distributee or the joint lives (or
         joint life expectancies) of the distributee and the distributee's
         designated Beneficiary, or for a specified period of ten years or more;
         any distribution to the extent such distribution is required under
         section 401(a)(9) of the Code; and the portion of any distribution that
         is not includible in gross income (determined without regard to the
         exclusion for net unrealized appreciation with respect to employer
         securities).

     (2) Eligible Retirement Plan. An eligible retirement plan is an individual
         retirement account described in section 408(a) of the Code, an
         individual retirement annuity described in section 408(b) of the Code,
         an annuity plan described in section 403(a) of the Code, or a qualified
         trust described in section 401(a) of the Code, that accepts the
         distributee's rollover distribution. However, in the case of an
         eligible rollover distribution to the surviving Spouse, an eligible
         retirement plan is an individual retirement account or individual
         retirement annuity.

     (3) Distributee. A distributee includes a Participant or former
         Participant. In addition, the Participant's or former Participant's
         surviving Spouse and the Participant's or former Participant's Spouse
         or former Spouse who is the alternate payee under a qualified domestic
         relations order, as defined in section 414(p) of the Code, are
         distributees with regard to the interest of the Spouse or former
         Spouse.

<PAGE>
 
     (4)  Direct Rollover. A direct rollover is a payment by the Plan to the
          eligible retirement plan specified by the distributee.

Aritcle X. Rights and Options on
Distributed Shares of Company Stock

10.1 Right of First Refusal

(a)  Shares of Company Stock distributed by the Trustee may be subject to a
     right of first refusal. Such a right shall provide that prior to any
     subsequent transfer, the shares must first be offered in writing to the
     Trust and then, if refused by the Trust, to the Company at a price equal to
     the greater of (1) the then fair market value of such shares of Company
     Stock as determined in good faith by the Committee, in accordance with
     Treasury regulation section 54.4975-11(d)(5) or (2) the purchase price
     offered by a buyer, other than the Company or Trustee, making an offer in
     good faith (as determined by the Committee) to purchase such shares of
     Company Stock.

(b)  The Trust or the Company, as the case may be, may accept the offer as to
     part or all of the Company Stock at any time during a period not exceeding
     14 days after the Trust receives the offer, on terms and conditions no less
     favorable to the Trust than those offered by the independent third-party
     buyer. Any installment purchase shall be made pursuant to a note secured by
     the shares purchased and shall bear a reasonable rate of interest as
     determined by the Committee.

(c)  If the offer is not accepted by the Trust, the Company, or both, then the
     proposed transfer may be completed within a reasonable period following the
     end of the 14-day period but only upon terms and conditions no less
     favorable to the shareholder than the terms and conditions of the third-
     party buyer's prior offer.

(d)  Shares of Company Stock that are publicly traded within the meaning of
     Treasury regulation section 54.4975-7(b)(1)(iv) at the time such right may
     otherwise be exercised shall not be subject to this right of first refusal.

10.2 Put Option

(a)  Shares of Company Stock acquired by the Trust shall be subject to a put
     option at the time of distribution if at such time the shares are not
     readily tradable on an established market within the meaning of section
     409(h)(1)(B) of the Code. The put option shall be exercisable by the
     Member, Beneficiary, Spouse, their donees, or by a person (including an
     estate or its distributee) to whom the Company Stock passes by reason of

<PAGE>
 
     the death of the Member, Beneficiary, or Spouse. The put option shall
     provide that for a period of at least 60 days following the date of
     distribution of the Company Stock, the holder of the option shall have the
     right to cause the Company, by notifying it in writing, to purchase such
     shares at their fair market value, as determined pursuant to section 5.2.
     If the put option is not exercised within such 60-day period, the option
     shall be exercisable for an additional period of 60 days in the following
     Plan Year. The Committee may give the Trustee the option to assume the
     rights and obligations of the Company at the time the put option is
     exercised, insofar as the repurchase of Company Stock is concerned.

(b)  If the entire adjusted balance of a Member's Accounts is distributed to the
     Member within one taxable year, payment of the price of the Company Stock
     purchased pursuant to an exercised put option shall be made in no more than
     five substantially equal annual payments, and the first installment shall
     be paid not later than 30 days after the Member exercises the put option.
     The Plan shall provide adequate security and pay a reasonable rate of
     interest on amounts not paid after 30 days. If the entire adjusted balance
     of a Member's Accounts is not distributed to him or her within one taxable
     year, payment of the price of the Company Stock purchased pursuant to an
     exercised put option shall be made in a single sum not later than 30 days
     after the Member exercises the put option.

Except as provided in sections 11.2 and 7.9, a Member is not entitled to any

Participant.

11.2 Dividends

Any cash dividend received by the Trustee on Company Stock allocated to the
Accounts of a Member, Beneficiary, or Spouse as of the record date for such
dividend shall be paid to such Member, Beneficiary, or Spouses. Any such payment
in cash must be made no later than 90 days after the end of the Plan Year in
which the dividend is received by the Trustee. Any such payment of cash
dividends on shares of Company Stock shall be accounted for as if the Member,
Beneficiary, or Spouse receiving such dividends were the direct owner of such
shares of Company Stock and such payment shall not be treated as a distribution
for purposes of Article X.
<PAGE>

     writing of the denial of the claim. Notice of a denial of a claim shall be
     written in a manner calculated to be understood by the claimant and shall

(b)  Within 60 days after the claimant receives the written notice of denial of
     the claim, or the date the claim is deemed denied pursuant to subsection

     account the nature of the benefit subject to the claim and other attendant
     circumstances, or within 60 days after the claim is deemed denied as set
     forth above, if applicable, the claimant may file a written request with
     the Committee that it conduct a full and fair review of the denial of the
     claimant's claim for benefits, including the holding of a hearing, if
     deemed necessary by the Committee. In connection with the claimant's appeal
     of the denial of the claimant's benefit, the claimant may review pertinent
     documents and may submit issues and comments in writing. The Committee
     shall render a decision on the appeal promptly, but not later than 60 days
     after the receipt of the claimant's request for review, unless special
     circumstances (such as the need to hold a hearing, if necessary) require an
     extension of time for processing, in which case the 60-day period may be
     extended to 120 days. The Committee shall notify the claimant in writing of
     any such extension. Such decision shall (1) include specific reasons for
     the decision, (2) be written in a manner calculated to be understood by the
     claimant, and (3) contain specific references to the pertinent Plan
     provisions upon which the decision is based.

12.7 Indemnity for Liability

The Company shall indemnify the Committee and each other fiduciary who is an
Employee of the Company, against any and all claims, losses, damages, expenses,
including counsel fees, incurred by said fiduciaries, and any liability,
including any amounts paid in settlement with such a fiduciary's approval,
arising from the fiduciary's action or failure to act, except when the same is
judicially determined to be attributable to the gross negligence or willful
misconduct of such fiduciary.

Article XIII. Amendment and Termination

13.1 Amendment

The Company reserves the right at any time and from time to time to amend the
Plan in whole or in part either retroactively or prospectively by action of the
Board or action of the Executive Committee of the Board, but no such amendment
shall authorize or permit any part of the corpus or income of the Trust to be
used for or diverted to purposes other than for the exclusive benefit of Members
or their Beneficiaries, or to deprive any of them of any funds then held for his
or her Account.

13.2 Termination

It is the intention of the Company to continue the Plan and to make
contributions thereto, but the Company reserves the right to terminate the Plan
in whole or in part as of any Valuation Date by action of the Board or action of
the Executive Committee of the Board and for any reason satisfactory to the
Board. The Company, however, shall not terminate the Plan while any Loan remains
outstanding and unpaid in whole or in part, without the prior written consent to
any such termination by all holders and guarantors, if any, of the Plan's
obligations under such Loan. Where any holder or guarantor has a representative
on the Committee, prior written consent will not be required if such
representative approves the amendment. Upon partial or full termination, all
affected Participants shall become fully vested, and upon permanent
discontinuance of contributions by the Company, all Participants shall become
fully vested. After termination of the Plan, the Committee and the Trust will
continue until the Accounts of each Participant have been distributed in
accordance with the terms of the Plan.

13.3 Merger, Sale

In the event of any merger or consolidation of the Plan with, or transfer in
whole or in part of the assets and liabilities of the Trust to another trust
fund held under any other plan of deferred compensation maintained or to be
established for the benefit of all or some of the Participants, the Plan shall
be so merged or consolidated, or the assets of the Trust applicable to such
Participants shall be so transferred, only if--

(a)  each Member would (if either the Plan or the other plan then terminated)
     receive a benefit immediately after the merger, consolidation, or transfer
     which is equal to or greater than the benefit he or she would have been
<PAGE>
 
     entitled to receive immediately before the merger, consolidation, or
     transfer (if the Plan had then terminated);

(b)  resolutions of the Board of Directors or of any new or successor employer
     of the affected Members, shall authorize such transfer of assets; and, in
     the case of the new or successor employer of the affected Members, its
     resolutions shall include an assumption of liabilities with respect to such
     Members' inclusion in the new employer's plan; and

(c)  such other plan and trust are qualified under section 401(a) and exempt
     under section 501(a) of the Code.

In the event a portion of the business of the Company is sold or discontinued,
the Board of Directors in its discretion may direct that all Members who are
employed by the new owner of that portion of the business shall become fully
vested.

13.4 Distribution Upon Termination

In the event of the termination of the Plan, there shall be distributed to each
Member, or to his or her Beneficiary in the case of a deceased Member, a benefit
equal to the sum of the value of the Member's Account as of the Valuation Date
on which termination occurs. If such benefits shall not exhaust the assets of
the Trust, any remaining assets shall be allocated to the Accounts of the
Members as though they were additional Employer Contributions, and in no event
shall any such assets revert to the Company or any Participating Employer.


<PAGE>
 
Article XIV. Extension of Plan to Affiliates

14.1 Participation in the Plan

Any Affiliate which desires to become a Participating Employer under the Plan
may elect, with the consent of the Board of Directors, to become a party to the
Plan and the related Trust by adopting the Plan for the benefit of its Eligible
Employees, effective as of the date specified in such adoption. The adoption
resolution or decision may contain such specific changes and variations in Plan
or Trust Agreement terms and provisions applicable to such Participating
Employer and its Employees as may be acceptable to the Board and the Trustee.
However, the sole, exclusive right of any other amendment of whatever kind or
extent to the Plan is reserved to the Board of Directors. The Board of Directors
may amend specific changes and variations in the Plan or Trust terms and
provisions as adopted by the Participating Employer in its adoption resolution
without the consent of such Participating Employer. The adoption resolution or
decision shall become, as to such adopting organization and its employees, a
part of this Plan as then amended or thereafter amended and the related Pension
Trust. It shall not be necessary for the adopting organization to sign or
execute the original or then amended Plan and Trust. The coverage date of the
Plan for any such adopting organization shall be that stated in the resolution
or decision of adoption, and from and after such effective date, such adopting
organization shall assume all the rights, obligations, and liabilities of an
individual employer entity hereunder and under the Trust. The administrative
powers and control of the Company, as provided in the Plan and Trust Agreement
shall not be diminished by reason of the participation of any such adopting
organization in the Plan and Trust Agreement.

14.2 Withdrawal from the Plan

Any Participating Employer may withdraw from the Plan and Trust after giving
notice to the Board of Directors, provided the Board consents to such
withdrawal. In the event of such withdrawal, the Committee shall cause a
valuation of the Trust Fund to be made to ascertain the value of assets which
are attributable to Members who are Employees of the terminating Participating
Employer or their Beneficiaries in the case of deceased Members and shall direct
the Trustee to segregate assets which are deemed to be so attributable to such
Members from the Trust, and to make distribution to the Members or their
Beneficiaries as if the Plan had terminated with respect to the Members or their
Beneficiaries of such Participating Employer.
<PAGE>
 
In the event such withdrawal constitutes a partial termination of this Plan,
only the affected Participants shall have fully vested and nonforfeitable rights
in the benefits to be provided by the allocations (unless they were already
fully vested prior to the partial termination). Distribution may be implemented
through continuation of the Trust, or transfer to another trust fund exempt from
tax under section 501 of the Code, or to a group annuity contract qualified
under Code section 401, or distribution may be made as an immediate cash
payment; provided, however, that no such action shall divert any part of such
fund to any purpose other than the exclusive benefit of the Employees of such
Participating Employer.
<PAGE>
 
Article XV.  Top-Heavy Provisions

The following provisions shall become effective in any Plan Year in which the
Plan is determined to be a top-heavy plan.

(a)  Determination of Top-Heavy. The Plan will be considered a top-heavy plan
     for the Plan Year if as of the last day of the preceding Plan Year (1) the
     account balances of Participants who are key employees (as defined in
     section 416(i) of the Code) exceeds 60 percent of the account balances of
     all Participants (the "60 Percent Test") or (2) the Plan is part of a
     required aggregation group and the required aggregation group is top-heavy.
     However, and notwithstanding the results of the 60 Percent Test, the Plan
     shall not be considered a top-heavy plan for any plan year in which the
     Plan is a part of a required or permissive aggregation group which is not
     top-heavy. The top-heavy ratio shall be computed pursuant to section 416(g)
     of the Code and the regulations issued thereunder. A "required aggregation
     group" is each plan of the Company in which a key employee is a participant
     and each other plan of the Company, if any, which enables such plan to meet
     the requirements of Code section 401(a)(4) or 410. The Company may treat
     any plan not required to be included in an aggregation group as being part
     of a "permissive aggregation group" if such group would continue to meet
     the requirements of Code sections 401(a)(4) and 410 with such plan being
     taken into account.

(b)  Minimum Benefit. The Company's contribution to a Participant's Matching
     Contribution Account under section 5.1 shall be 3 percent of the
     Participant's Compensation, except that this subsection (b) shall not apply
     if--

     (1)  the Participant is also a participant in the Pension Plan,

     (2)  the Pension Plan is a top-heavy plan, and

     (3)  the Participant receives from the Pension Plan the defined benefit
          minimum required under section 416(c)(1) of the Code.
<PAGE>
 
XVI. Miscellaneous Provisions

16.1 Spendthrift Provisions

The interests of Employees and their Beneficiaries in the Plan shall not be
subject to the claims of any creditor, any Spouse for alimony or support, or
others, or to legal process, and may not be voluntarily or involuntarily
alienated or encumbered.

Notwithstanding the foregoing, the Plan shall make all payments required by a
qualified domestic relations order within the meaning of Code section 414(p).
The Committee shall establish a procedure to determine the qualified status of a
domestic relations order and to administer distributions under a qualified
order. In no event shall a domestic relations order be determined to be a
qualified domestic relations order if it requires the Plan to make distributions
to an alternate payee prior to the date that a Member attains "earliest
retirement age." Notwithstanding the foregoing, the Plan may make a distribution
to an alternate payee prior to the date that a Member attains "earliest
retirement age" if the qualified domestic relations order provides that the Plan
and the alternate payee may agree in writing to the earlier distribution and the
distribution is made pursuant to such a written agreement. For purposes of a
qualified domestic relations order, "earliest retirement age" means the date on
which the earliest to occur of--

(a)  the date the Member is entitled to a distribution under this Plan, or
     terminates from employment,

(b)  the later of (i) the date the Member attains age 50, or (ii) the earliest
     date on which the Member could begin receiving benefits under this Plan if
     the Member separated from service.

16.2 Incompetency

Every person receiving or claiming benefits under the Plan shall be presumed to
be mentally competent and of age until the Committee receives a written notice,
in a form and manner acceptable to it, that such person is incompetent or a
minor, and that a guardian, conservator, or other person legally vested with the
care of his estate has been appointed. In the event that the Committee finds
that any person to whom a benefit is payable under the Plan is unable to
properly care for his or her affairs, or is a minor, then any payment due
(unless a prior claim therefor shall have been made by a duly appointed legal
representative) may be paid to the Spouse, a child, a parent, or a brother or
<PAGE>
 
sister, or to any person deemed by the Committee to be authorized to care for
such person otherwise entitled to payment.

In the event a guardian, executor, administrator, or conservator of the estate
of any person receiving or claiming benefits under the Plan shall be appointed
by a court of competent jurisdiction, payments shall be made to such guardian,
executor, administrator, or conservator provided that proper proof of
appointment is furnished in a form and manner suitable to the Committee. Any
payment made under the provisions of this section 16.2 shall be a complete
discharge of any liability therefor under the Plan.

16.3 Unclaimed Funds

Each Member shall keep the Committee informed of the Member's current address
and the current address of the Member's Spouse and Beneficiaries. Neither the
Company or any Affiliate, the Committee, nor the Trustee shall be obligated to
search for the whereabouts of any such person. If the then current location of a
Member is not made known to the Committee within three years after the date on
which the Committee directs the distribution to the Member of the Member's
Accounts, distribution may be made as though the Member 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 Member,
the Committee is unable to locate any individual who would receive a
distribution upon the death of the Member pursuant to Article IX, the Member's
Accounts shall be deemed a Forfeiture; provided, however, that if the Member,
Beneficiary, or Spouse makes a claim for any amount that has been so forfeited,
the forfeited benefits shall be reinstated. The amount required to restore such
benefits shall be made up from Forfeitures and, to the extent necessary,
Employer Contributions prior to their allocation pursuant to section 7.4.

16.4 Rights Against the Company

Neither the establishment of the Plan, nor of the Trust, nor any modification
thereof, nor any distributions hereunder shall be construed as giving to any
person whomsoever any legal or equitable rights against the Committee, the
Company, or the officers, directors, or shareholders as such of the Company, or
as giving any Employee or Member the right to be retained in the employ of the
Company. All benefits payable under the Plan shall be paid or provided for
solely from the Trust, and the Company shall have no liability or responsibility
for benefit distributions other than to make contributions to the Trust as
herein provided.
<PAGE>
 
16.5 Illegality of Particular Provision

The illegality of any particular provision of this Plan shall not affect the
other provisions thereof, but the Plan shall be construed in all respects as if
such invalid provision were omitted.

16.6 Effect of Mistake

In the event of a mistake or misstatement as to the age, eligibility,
compensation, service or participation of a Member or the amount of
distributions made or to be made to a Member or other person, the Committee
shall, to the extent it deems possible, cause to be withheld or accelerated, or
otherwise make adjustment of, such amounts as will in its judgment accord to
such Member or other person, or distribution to which he or she is properly
entitled under the Plan.

16.7 Compliance with Federal and State Securities Laws

(a)  The Company will take all necessary steps to comply with any applicable
     registration or other requirements of federal or state securities laws from
     which no exemption is available.

(b)  Stock certificates distributed to Members, Beneficiaries, or Spouses may
     bear such legends concerning restrictions imposed by federal or state
     securities laws, and concerning other restrictions and rights under the
     Plan, as the Committee in its discretion may determine.

16.8 No Discrimination

Whenever in the administration of the Plan action by the Committee is required
with respect to eligibility or classification of Employees, contributions, or
benefits, such action shall be uniform in nature as applied to all persons
similarly situated, and no such action shall discriminate in favor of Employees
who are Highly Compensated Employees.

16.9 Exclusive Benefit of Employees

(a)  All Employer Contributions made pursuant to the Plan shall be held by the
     Trustee in accordance with the terms of the Trust Agreement for the
     exclusive benefit of those Employees who are Members under the Plan,
     including former Employees, Beneficiaries, and Spouses, and shall be
     applied to provide benefits under the Plan and to pay expenses of
     administration of the Plan and the Trust to the extent that such expenses
     are not otherwise paid. At no time prior to the satisfaction of all
<PAGE>
 
     liabilities with respect to such Members, their Beneficiaries and Spouses
     shall any part of the Trust Fund (other than such part as may be required
     to pay administration expenses) be used for, or diverted to, purposes other
     than the exclusive benefit of such Members, their Beneficiaries and
     Spouses.

(b)  Notwithstanding section 16.8(a)--

     (1)  if an Employer Contribution under the Plan is conditioned on initial
          qualification of the Plan under section 401(a) of the Code, and the
          Plan receives an adverse determination with respect to its initial
          qualification, the Trustee shall, upon written request of the Company,
          or Participating Employer making the contribution, return to the
          Company or Participating Employer the amount of the contribution
          (increased by earnings attributable thereto and reduced by losses
          attributable thereto) within one calendar year after the date that
          qualification of the Plan is denied, provided that the application for
          the determination is made by the time prescribed by law for filing the
          employer's return for the taxable year in which the Plan is adopted,
          or such later date as the Secretary of the Treasury may prescribe;

     (2)  if an Employer Contribution is conditioned upon the deductibility of
          such contribution under section 404 of the Code, then, to the extent
          the deduction is disallowed, the Trustee shall, upon written request
          of the Company or Participating Employer making the contribution,
          return the contribution to the extent disallowed to the Company or
          Participating Employer within one year after the date the deduction is
          disallowed;

     (3)  if an Employer Contribution or any portion thereof is made by the
          Company or a Participating Employer by a mistake of fact, the Trustee
          shall, upon written request of the Company or Participating Employer,
          return the contribution or the portion to the Company or Participating
          Employer within one year after the date of payment to the Trustee; and

     (4)  earnings attributable to amounts to be returned to the Company or
          Participating Employer pursuant to paragraph (2) or (3) shall not be
          returned to the Company or Participating Employer, and losses
<PAGE>
 
          attributable to amounts to be returned pursuant to paragraph (2) or
          (3) shall reduce the amount to be so returned.

16.10 Governing Law

The provisions of the Plan shall be construed, administered, and enforced in
accordance with the laws of Illinois, to the extent such laws are not superseded
by laws of the United States. All Employer Contributions to the Trust shall be
deemed to be made in Illinois.

16.11 Change-in-Control

Notwithstanding any provision of the Plan to the contrary, if a Change-in-
Control (as defined below) occurs--

(a)  each Participant who is an Employee on the date the Change-in-Control
     occurs shall be 100 percent vested in the adjusted balance of the
     Participant's Company Stock and Other Investments Accounts;

(b)  no merger, transfer of assets, or other similar transactions involving the
     Plan shall be permitted until all Loans outstanding at the time of the
     Change-in-Control have been repaid and all shares of Company Stock held in
     a Suspense Account in respect thereof have been released and allocated to
     Participants' Company Stock Account of Participants employed as of the
     Change-in-Control date;

(c)  no other action may be taken pursuant to Article XIII that would have the
     affect of diverting such shares to the Company Stock Accounts of
     Participants who are not employees of the Company or a Participating
     Employer as of the Change-in-Control date; or

(d)  if, in connection with the Change-in-Control, Company Stock held by the
     Plan has been sold for consideration other than securities constituting
     Company Stock, then the date that the Change-in-Control occurs shall be a
     special Valuation Date and each Participant with an Account under the Plan
     as of the date the Change-in-Control occurs shall be entitled to share in
     the proceeds of such sale in the manner described in section 7.7(b).

For purposes of this section, a "Change-in-Control" shall be deemed to occur on
the earliest of--
<PAGE>
 
(1)  the receipt by Northern Trust Corporation (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, of more than 30 percent of the
     outstanding capital stock of the Corporation entitled to vote for the
     election of directors ("voting stock");

(2)  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 percent of the outstanding voting stock of
     the Corporation;

(3)  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 percent 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 percent of the voting stock; or

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

                              * * * * * * * * * *

In Witness Whereof, the Company has caused this Plan to be executed on its
behalf by its duly authorized officer this 21st day of November, 1995.

                                       TO
                          THE NORTHERN TRUST EMPLOYEE
                              STOCK OWNERSHIP PLAN

WHEREAS, The Northern Trust Company (the "Company") maintains the Northern Trust
Company Employee Stock Ownership Plan, as amended and restated effective January
1, 1989 (the "Plan"); and

WHEREAS, amendment of the Plan is now deemed desirable in order to clarify
certain provisions of the Plan;

NOW, THEREFORE, by virtue and in exercise of the amending power reserved to the
Company under Section 13.1 of the Plan, and pursuant to the authority delegated
to the undersigned officer in a resolution of the Board of Directors dated July
18, 1995, the Plan is hereby amended effective January 1, 1989, in the following
particulars:

l.  Section 3.4(a) is amended in its entirety to read as follows:

"(a) Vesting Service shall be computed on the following bases:  (i) prior to
     July l, l993, an Employee shall receive credit for each calendar quarter
     during which the Employee earned at least one (1) Hour of Service or
     otherwise would receive credit for Vesting Service pursuant to this
     subsection (b) below; and (ii) from and after July l, l993, an Employee
     shall receive credit for each calendar month during which the Employee
     earned at least one (1) Hour of Service or otherwise would receive credit
     for Vesting Service pursuant to subsection (b) below."

2.  Section 3.4(b)(i) is amended in its entirety to read as follows:

                          RESTATEMENT OF SUPPLEMENTAL
                           EMPLOYEE TRUST AGREEMENT



          This Restated Trust Agreement made this 18th day of June, 1996, by and
between The Northern Trust Company ("Company") and Harris Trust & Savings Bank
("Trustee").

          WHEREAS, Company has adopted the nonqualified deferred compensation
Plans as listed in Appendix A;

          WHEREAS, Company established a trust (hereinafter called "Trust")
September 14, 1989, which was restated effective September 14, 1989, and now
wishes to again restate the Trust, effective June 18, 1996, the Trust assets to
be held therein, subject to the claims of Company's creditors in the event of
Company's insolvency, as herein defined, until paid to Plan participants and
their beneficiaries in such manner and at such times as specified in the Plans;

          WHEREAS, it is the intention of the parties that this Trust shall
constitute an unfunded arrangement and shall not affect the status of the Plans
as an unfunded plan maintained for the purpose of providing deferred
compensation for a select group of management or highly compensated employees
for purposes of Title I of the Employee Retirement Income Security Act of 1974;

          WHEREAS, it is the intention of Company to make contributions to the
Trust to provide itself with a source of funds to assist it in the meeting of
its liabilities under the Plans;

          NOW, THEREFORE, the parties do hereby restate the Trust in its
entirety as follows:

          SECTION 1.  ESTABLISHMENT OF TRUST.

          (a)  Company hereby establishes the Supplemental Employee Trust of The
Northern Trust Company, the principal of the Trust to be held, administered and
disposed of by Trustee as provided in this Trust Agreement.

          (b)  The Trust hereby established shall be irrevocable. The Trust
shall only be amended with the written consent of the Trustee and the Company;
provided that no amendment shall (i) reduce or otherwise affect any amounts held
in the Trust as of the effective date of such amendment, or (ii) require the
distribution of any such amounts at any date earlier than the applicable
distribution dates provided hereunder and under the terms of the Plans as of the
effective date of such amendment.
<PAGE>
 
          (c)  The Trust is intended to be a grantor trust, of which Company is
the grantor, within the meaning of subpart E, part I, subchapter J, Chapter 1,
subtitle A of the Internal Revenue Code of 1986, as amended, and shall be
construed accordingly.

          (d)  The principal of the Trust, and any earnings thereon, shall be
held separate and apart from other funds of Company and shall be used
exclusively for the uses and purposes of Plan participants and general creditors
as herein set forth. Plan participants and their beneficiaries shall have no
preferred claim on, or any beneficial ownership interest in, any assets of the
Trust. Any rights created under the Plans and this Trust Agreement shall be mere
unsecured contractual rights of Plan participants and their beneficiaries
against Company. Any assets held by the Trust will be subject to the claims of
Company's general creditors under federal and state law in the event of
Insolvency, as defined in Section 3(a) herein.

          (e)  Company, in its sole discretion, may at any time, or from time to
time, make additional deposits of cash or other property in trust with Trustee
to augment the principal to be held, administered and disposed of by Trustee as
provided in this Trust Agreement. Neither Trustee nor any Plan participant or
beneficiary shall have any right to compel such additional deposits.

          SECTION 2.  PAYMENTS TO PLAN PARTICIPANTS AND THEIR BENEFICIARIES.

          (a)  Company shall deliver to Trustee a schedule (the "Payment
Schedule") that indicates the amounts payable in respect of each Plan
participant (and his or her beneficiaries), that provides a formula or other
instructions acceptable to Trustee for determining the amount so payable, the
form in which such amount is to be paid as provided for or available under the
Plans), and the time of commencement for payment of such amounts. Except as
otherwise provided herein, Trustee shall make payments to Plan participants and
their beneficiaries in accordance with such Payment Schedule. The Trustee shall
make provision for the reporting and withholding of any federal, state or local
taxes that may be required to be withheld with respect to the payment of
benefits pursuant to the terms of the Plans and shall pay amounts withheld to
the appropriate taxing authorities or determine that such amounts have been
reported, withheld and paid by Company.

          (b)  The entitlement of a Plan participant or his or her beneficiaries
to benefits under the Plans shall be determined by Company or such party as it
shall designate under the Plans, and any claim for such benefits shall be
considered and reviewed under the procedures set out in the Plans.

          (c)  Company may make payment of benefits directly to Plan
participants or their beneficiaries as they become due under the terms of the
Plans. Company shall notify Trustee of its decision to make payment of benefits
directly prior to the time amounts are payable to participants or their
beneficiaries. In addition, if the principal of the Trust, and any earnings
thereon, are not sufficient to make payments of benefits in accordance with the
terms of the Plans, Company shall make the balance of each such payment as it
falls due. Trustee shall notify Company where principal and earnings are not
sufficient.

                                      -2-

     SECTION 3.  TRUSTEE RESPONSIBILITY REGARDING PAYMENTS TO TRUST
     BENEFICIARY WHEN COMPANY IS INSOLVENT.

     (a)  Trustee shall cease payment of benefits to Plan participants and their
beneficiaries if the Company is Insolvent. Company shall be considered
"Insolvent" for purposes of this Trust Agreement if (i) Company is unable to pay
its debts as they become due, or (ii) Company is subject to a pending proceeding
as a debtor under the United States Bankruptcy Code.

     (b)  At all times during the continuance of this Trust, as provided in
Section 1(d) hereof, the principal and income of the Trust shall be subject to
claims of general creditors of Company under federal and state law as set forth
below.

          (1)  The Board of Directors and the Chief Executive Officer of Company
     shall have the duty to inform Trustee in writing of Company's insolvency.
     If a person claiming to be a creditor of Company alleges in writing to
     Trustee that Company has become insolvent, Trustee shall determine whether
     Company is insolvent and, pending such determination, Trustee shall
     discontinue payment of benefits to Plan participants or their
     beneficiaries.

          (2)  Unless Trustee has actual knowledge of Company's insolvency or
     has received notice from Company or a person claiming to be a creditor
     alleging that Company is Insolvent, Trustee shall have no duty to inquire
     whether Company is insolvent. Trustee may in all events rely on such
     evidence concerning Company's solvency as may be furnished to Trustee and
     that provides Trustee with a reasonable basis for making a determination
     concerning Company's solvency.

          (3)  If at any time Trustee has determined that Company is Insolvent,
     Trustee shall discontinue payments to Plan participants or their
     beneficiaries and shall hold the assets of the Trust for the benefit of
     Company's general creditors. Nothing in this Trust Agreement shall in any
     way diminish any rights of Plan participants or their beneficiaries to
     pursue their right as general creditors of Company with respect to benefits
     due under the Plans or otherwise.

          (4)  Trustee shall resume the payment of benefits to Plan participants
     or their beneficiaries in accordance with Section 2 of this Trust Agreement
     only after Trustee has determined that Company is not Insolvent (or is no
     longer Insolvent).

     (c)  Provided that there are sufficient assets, if Trustee discontinues the
payment of benefits from the Trust pursuant to Section 3(b) hereof and
subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments due to Plan
participants or their beneficiaries under the terms of the Plans for

                                      -3-
<PAGE>
 
the period of such discontinuance, less the aggregate amount of any payments
made to Plan participants or their beneficiaries by Company in lieu of the
payments provided hereunder during any such period of discontinuance.

     SECTION 4.  PAYMENTS TO COMPANY.

     Except as provided in Sections 2 and 3 hereof, Company shall have no right
or power to direct Trustee to return to Company or to divert to others any of
the Trust assets before all payment of benefits have been made to Plan
participants and their beneficiaries pursuant to the terms of the Plans.

     SECTION 5.  INVESTMENT AUTHORITY.

     (a)  Subject to paragraph (b) below of this Section 5, subject further to
such investment guidelines as may be issued to Trustee from time to time by
Company, Trustee may invest and reinvest Trust assets in property of any kind.

     (b)  Company may, by written notice to Trustee, assume investment
responsibility for any portion of the Trust assets; Trustee shall act with
respect to such assets only as directed by Company and shall have no
responsibility to make any investment review of such assets.

     SECTION 6.  DISPOSITION OF INCOME.

     During the term of this Trust, all income received by the Trust, net of
expenses and taxes, shall be accumulated and reinvested.

     SECTION 7.  ACCOUNTING BY TRUSTEE.

     Trustee shall keep accurate and detailed records of all investments,
receipts, disbursements and all other transactions required to be made,
including such specific records as shall be agreed upon in writing between
Company and Trustee. Within 30 days following the close of each calendar year
and within 30 days after the removal or resignation of Trustee, Trustee shall
deliver to Company a written account of its administration of the Trust during
such year or during the period from the close of the last preceding year to the
date of such removal or resignation, setting forth all investments, receipts,
disbursements and other transactions effected by it, including a description of
all securities and investments purchased and sold with the cost or net proceeds
of such purchases or sales (accrued interest paid or receivable being shown
separately), and showing all cash, securities and other property held in the
Trust at the end of such year or as of the date of such removal or resignation,
as the case may be.

     SECTION 8.  RESPONSIBILITY OF TRUSTEE.

     (a)  Trustee shall act with the care, skill, prudence and diligence under
the circumstances then prevailing that a prudent person acting in like capacity
and familiar with such matters would use in the conduct of an enterprise of
alike character and with like aims, provided, however, that Trustee shall incur
no liability to any person for any action taken pursuant to a direction, request
or approval given by Company which is contemplated by, and in conformity with,
the terms of the Plans for this Trust and is given in writing by Company. In the
event of a dispute between Company and a party, Trustee may apply to a court of
competent jurisdiction to resolve the dispute.

     (b)  If Trustee undertakes or defends any litigation arising in connection
with this Trust, Company agrees to indemnify Trustee against Trustee's costs,
expenses and liabilities (including, without limitation, attorneys' fees and
expenses) relating thereto and to be primarily liable for such payments. If
Company does not pay such costs, expenses and liabilities in a reasonably timely
manner, Trustee may obtain payment from the Trust.

     (c)  Trustee may consult with legal counsel (who may also be counsel for
Company generally) with respect to any of its duties or obligations hereunder.

     (d)  Trustee may hire agents, accountants, actuaries, investment advisors,
financial consultants or other professionals to assist it in performing any of
its duties or obligations hereunder.

     (e)  Trustee shall have, without exclusion, all powers conferred on
Trustees by applicable law, unless expressly provided otherwise herein,
provided, however, that if an insurance policy is held as an asset of the Trust,
Trustee shall have no power to name a beneficiary of the policy other than the
Trust, to assign the policy (as distinct from conversion of the policy to a
different form) other than to a successor Trustee, or to loan to any person the
proceeds of any borrowing against such policy.

     (f)  Notwithstanding any powers granted to Trustee pursuant to this Trust
Agreement or to applicable law, Trustee shall not have any power that could give
this Trust the objective of carrying on a business and dividing the gains
therefrom, within the meaning of Section 301.7701-2 of the Procedure and
Administrative Regulations promulgated pursuant to the Internal Revenue Code.

     SECTION 9.  COMPENSATION AND EXPENSES OF TRUSTEE.

     Company shall pay all administrative and Trustee's fees and expenses. If
not so paid, the fees and expenses shall be paid from the Trust.

                                      -5-

     SECTION 10.  RESIGNATION AND REMOVAL OF TRUSTEE.

accordance with Section 11 hereof, by the effective date of resignation or
removal under paragraph(s) (a) or (b) of this Section. If no such appointment
has been made, Trustee may apply to a court of competent jurisdiction for
appointment of a successor or for instructions. All expenses of Trustee in
connection with the proceeding shall be allowed as administrative expenses of
the Trust.

     SECTION 11.  APPOINTMENT OF SUCCESSOR.

     If Trustee resigns or is removed in accordance with Section 10(a) or (b)
hereof, Company may appoint any third party, such as a bank trust department or
other party that may be granted corporate trustee powers under state law, as a
successor to replace Trustee upon resignation or removal. The appointment shall
be effective when accepted in writing by the new Trustee, who shall have all of
the rights and powers of the former Trustee, including ownership rights in the

("Trust Agreement"). Amounts allocated hereunder to the Supplemental ESOP

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

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

furnished by any actuary, accountant, controller, counsel or other person
employed or engaged by the Committee with respect to the Plan.

                           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, distribution 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 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.

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 30th day of April, 1996.

In the event an employee of the Company who is ineligible to participate in the

(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).

day of such Plan Year.

                   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.

4.2  Company Securities.  Notwithstanding anything to the contrary 
<PAGE>
 
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.

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
be distributed to those persons entitled to receive distributions of
<PAGE>
 
the Participant's accounts under the Qualified Plan.


                                  ARTICLE VI

provisions thereof. The Committee shall have discretion to interpret and
construe the provisions of the Plan.

7.1  Amendment or Termination.  The Company intends the Plan to be permanent but

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, distribution 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 shall remain subject to the general creditor of the
Company. The Plan
<PAGE>
 
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 paid
shall be a complete discharge of any liability of the Company and
<PAGE>
 
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 the location 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 Before-Tax Deposit Account and Supplemental Matching
Contribution 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 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.

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.

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

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.

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.

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.

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 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
<PAGE>
 
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.

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 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.
