Date:  December 10, 1993
 
  To:  Compensation and Benefits Committee of
       the Board of Directors
 
From:  William Setterstrom
 
  Re:  Plan Amendments

Amendments shall be made to the following retirement plans:

.  The Northern Trust Company Pension Plan

.  The Northern Trust Company Thrift-Incentive Plan

.  The Northern Trust Company Employee Stock Ownership Plan

.  Supplemental Pension Plan for Employees of the Northern Trust Company

.  Supplemental Thrift-Incentive Plan for Employees of the Northern Trust
   Company

Amendments to The Northern Trust Company Employee Stock Ownership Plan

. Seasonal and temporary employees will not be eligible for participation in the
  ESOP (to be effective as soon as administratively practicable).

. Effective August 5, 1993, the service crediting rules under the ESOP shall be
  amended to comply with the requirements of the Family and Medical Leave Act of
  1993.

. Foreign nationals on temporary assignment who continue participation in the
  pension plan of the foreign affiliate from which they were transferred will be
  excluded from participation in the ESOP.

. Foreign nationals who do not continue participation in the pension plan of the
  foreign affiliate from which they were transferred will participate in the
  ESOP. Service with the foreign affiliate will be counted for vesting but not
  credited service.

. Employees who are awarded severance pay at termination of employment shall
  receive "imputed" service credit equal to the maximum salary continuation
  period permitted under The Northern Trust Severance Pay Plan. This amendment
  is to be effective as soon as administratively possible.



Amendments to the Supplemental Pension Plan for Employees of The Northern Trust
Company (the "Supplemental Pension Plan")

. The benefit formula will be amended to provide that a participant's benefit
  will be calculated by subtracting the lump sum value of a participant's
  benefit under the Pension Plan based upon his or her single life annuity
  benefit (after considering Code section 401(a)(17) and 415 restrictions) from
  the lump sum value of a participant's benefit under the Pension Plan, based
  upon the participant's qualified joint and lump sum benefit, without
  consideration of such statutory restrictions.

. If a participant's entire benefit under the Pension Plan has been distributed
  due to the payment of a QDRO, the participant will still be entitled to a
  benefit under the Supplemental Pension Plan, based upon the benefit to which
  he would have been entitled, if not for the QDRO. However, the participant's
  benefit under the Supplemental Plan will not replace any amount actually paid
  to such alternate payee.

. Payments from the Supplemental Pension Plan to a nonretirement eligible
  employee shall be made on the last day of the third calendar month following
  the calendar month in which the employee terminates employment.

The above amendments shall be applicable to "covered employees" (as defined
under Code section 162(m)(3)) only to the extent permitted to allow payments to
be covered under Code section 162(m)(4)(D).

Amendments to the Supplemental Thrift-Incentive Plan for Employees of The
Northern Trust Company (the "Supplemental TIP")

. An employee is eligible to make salary deferrals if his or her base rate of
  compensation as of November 30 of the prior plan year exceeds the 401(a)(17)
  compensation limit of such prior plan year and such employee meets the plan's
  eligibility requirement as of January 1. However, if the compensation limit
  for the plan year for which participation is being determined is known by
  November 30 of such prior plan year, participation will be based upon such
  limit. Employees who are not eligible under the above criteria, but whose
  employer or employee contributions to TIP are limited because their base
  compensation exceeds the Code section 401(a)(17) compensation limit or the
  contribution limit set forth in Code section 415(c)(1)(A), will be eligible to
  participate for purposes of employer matching contributions only, as of the
  date they are no longer eligible to make contributions to TIP.

. Only employees eligible to make salary deferrals who actually make salary
  deferrals will receive employer matching contributions.

. Employees who are not eligible to make salary deferrals (i.e., employees who
  did not meet the eligibility requirements to make salary deferral elections on
  January 1, but who cannot make further contributions to TIP because base
  compensation exceeds the compensation limits or the contribution limits of
  Code section 415(c)(1)(A)) will receive employer matching contributions based
  upon their rate of contribution to TIP at the time their contributions ceased
  due to the compensation limit.

. Employees who meet the eligibility requirements for plan participation will be
  allowed to elect (1) to decline participation in the plan, (2) to make
  contributions to the plan during the entire plan year (TIP contribution must
  be at least 4 percent), or (3) to begin contributing to the plan after they
  are no longer able to contribute to TIP.

. The maximum salary before-tax deposit to the plan cannot be greater than 12
  percent less the employee's contributions to TIP (changed from 13 percent).

The above amendments shall be applicable to "covered employees" (as defined
under Code section 162(m)(3)) only to the extent permitted to allow payments to
be covered under Code section 162(m)(4)(D).



. Employees who are awarded severance pay at termination of employment shall
  receive "imputed" service credit equal to the maximum salary continuation
  period permitted under The Northern Trust Severance Pay Plan. This amendment
  is to be effective as soon as administratively possible.

Amendments to the Supplemental Pension Plan for Employees of The Northern Trust
Company (the "Supplemental Pension Plan")

. The benefit formula will be amended to provide that a participant's benefit
  will be calculated by subtracting the lump sum value of a participant's
  benefit under the Pension Plan based upon his or her single life annuity
  benefit (after considering Code section 401(a)(17) and 415 restrictions) from
  the lump sum value of a participant's benefit under the Pension Plan, based
  upon the participant's qualified joint and lump sum benefit, without
  consideration of such statutory restrictions.

. If a participant's entire benefit under the Pension Plan has been distributed
  due to the payment of a QDRO, the participant will still be entitled to a
  benefit under the Supplemental Pension Plan, based upon the benefit to which
  he would have been entitled, if not for the QDRO. However, the participant's
  benefit under the Supplemental Plan will not replace any amount actually paid
  to such alternate payee.

. Payments from the Supplemental Pension Plan to a nonretirement eligible
  employee shall be made on the last day of the third calendar month following
  the calendar month in which the employee terminates employment.

The above amendments shall be applicable to "covered employees" (as defined
under Code section 162(m)(3)) only to the extent permitted to allow payments to
be covered under Code section 162(m)(4)(D).
