                      RESTATED SUPPLEMENTAL PENSION PLAN
                  FOR EMPLOYEES OF THE NORTHERN TRUST COMPANY


The Northern Trust Company Supplemental Plan was adopted on September l6, l975
and amended through December l6, l986. The portions of that plan that pertained
to The Northern Trust Company Pension Plan were amended and restated by The
Restated Supplemental Pension Plan for Employees of The Northern Trust Company,
initially adopted effective September l, l989, restated effective September l,
l989 and further amended and restated effective January 1, 1996 ("the Restated
Supplemental Pension Plan"). The Northern Trust Company desires to further amend
and restate The Restated Supplemental Pension Plan, which has been established
and is maintained by The Northern Trust Company solely for the purpose of
providing benefits for certain employees of the Company who participate in The
Northern Trust Company Pension Plan and whose benefits under such plan are
limited by the restrictions on benefits imposed by Section 40l(a)(17) and
Section 415 of the Code.

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

                                  ELIGIBILITY


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


                                  ARTICLE III
                         SUPPLEMENTAL PENSION BENEFIT


3.1  Amount.  The Supplemental Pension Benefit payable to an eligible
Participant shall be the difference between (a) the lump sum value of the
Participant's Qualified Plan Pension Benefit based on a straight life annuity
over the lifetime of the Participant only (i) after considering Code Section
401(a)(17) and Section 415 restrictions, and (ii) compensation for any period of
time considered in computing such

 
Benefit is determined including amounts of base salary and bonus earned with
respect to such period of time and deferred because of Internal Revenue Code
Section 162(m) limitations under the Northern Trust Corporation Annual
Performance Plan, and (b) the lump sum value of the Participant's Qualified Plan
Pension Benefit, based on the Participant's qualified joint and survivor lump
sum benefit (without consideration of such statutory restrictions).

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

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

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

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

3.2  Vesting of Benefit.  Each Participant shall vest in his Supplemental
Pension Benefit in accordance with the vesting schedule applicable to his
Qualified Plan Pension Benefit set forth in the

 
Qualified Plan. Notwithstanding the preceding sentence or any other provision of
the Plan, each Participant shall become fully vested in his Supplemental Pension
Benefit on the effective date of a Change-in-Control.

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

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

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

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


                                  ARTICLE IV
                         SUPPLEMENTAL SURVIVOR BENEFIT


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

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

 
(b)  the lump sum value of the Qualified Plan Survivor Benefit actually payable
to the Beneficiary under the Qualified Plan.

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


                                   ARTICLE V
                          ADMINISTRATION OF THE PLAN

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

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


                                  ARTICLE VI
                           AMENDMENT OR TERMINATION

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

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


                                  ARTICLE VII
                              GENERAL PROVISIONS

7.1  Funding.  The Company may contribute amounts to fund the benefits under the
Plan to a trust ("Trust") established pursuant to a trust

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

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

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

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

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

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

7.7  Incapacity of Recipient.  If any benefit under the Plan shall be payable to
a minor or a person not adjudicated incompetent but who, by reason of illness or
mental or physical disability, is, in the opinion

 
of the Committee, unable to properly manage his affairs, such benefit shall be
paid in such of the following ways as the Committee deems best: (a) to the
person directly; (b) in the case of a minor, to a custodian under any Uniform
Gift to Minors Act for the person; or (c) 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.
