                             Capital Stock Classes

    The total number of shares of all classes of capital stock which the
Corporation has the authority to issue is 71,000,000 shares, which are divided
into two classes as follows:

    1,000,000 shares of Preferred Stock (Preferred Stock) without par value, and

    70,000,000 shares of Common Stock (Common Stock) $1.66-2/3 par value per
share.

    The designations, voting powers, preferences and relative, participating,
optional or other special rights, and qualifications, limitations or
restrictions of the above classes of stock are as follows:

                                       I

                                Preferred Stock

1.  Issuance in Series.

    Shares of Preferred Stock may be issued in one or more series at such time
or times, and for such consideration or considerations as the Board of Directors
may determine.  All shares of any one series of Preferred Stock will be
identical with each other in all respects, except that shares of any one series
issued at different times may differ as to dates from which dividends thereon
may be cumulative.  All series will rank equally and be identical in all
respects, except as permitted by the following provisions of paragraph 2 of this
Division I.

2.  Authority of the Board with respect to Series.

    The Board of Directors is authorized, at any time and from time to time, to
provide for the issuance of shares of Preferred Stock in one or more series with
such designations, preferences and relative, participating, optional or other
special rights and qualifications, limitations or restrictions thereof as are
stated and expressed in the resolution or resolutions providing for the issue
thereof adopted by the Board of Directors, and as are not stated and expressed
in this Restated Certificate of Incorporation or any amendment thereto
including, but not limited to, determination of any of the following:

      (a)  the distinctive serial designation and the number of shares
    constituting a series;

                                  Common Stock

1. Dividends.

  Subject to the preferential rights of the Preferred Stock, the holders of the
Common Stock are entitled to receive, to the extent permitted by law, such
dividends as may be declared from time to time by the Board of Directors.

2. Liquidation.

  In the event of the voluntary or involuntary liquidation, dissolution,
distribution of assets or winding up of the Corporation, after distribution in
full of the preferential amounts, if any, to be distributed to the holders of
shares of Preferred Stock, holders of Common Stock shall be entitled to receive
all of the remaining assets of the Corporation of whatever kind available for
distribution to stockholders ratably in proportion to the number of shares of
Common Stock held by them respectively.  The Board of Directors may distribute
in kind to the holders of Common Stock such remaining assets of the Corporation
or may sell, transfer or otherwise dispose of all or any part of such remaining
assets to any other corporation, trust or other entity and receive payment
therefor in cash, stock or obligations of such other corporation, trust or other
entity, or any combination thereof, and may sell all or any part of the
consideration so received and distribute any balance thereof in kind to holders
of Common Stock.  The merger or consolidation of the Corporation into or with
any other corporation, or the merger of any other corporation into it, or any
purchase or redemption of shares of stock of the Corporation of any class, shall
not be deemed to be a dissolution, liquidation or winding up of the Corporation
for the purposes of this paragraph.

3. Voting Rights.

  Except as may be otherwise required by law or this Restated Certificate of
Incorporation, each holder of Common Stock has one vote in respect of each share
of stock held by him of record on the books of the Corporation on all matters
voted upon by the stockholders.

                                      III

                                Other Provisions

1. Preemptive Rights.

  No stockholder shall have any preemptive right to subscribe to an additional
issue of stock of any class or series or to any securities of the Corporation
convertible into such stock.

2. Changes in Authorized Capital Stock.

  Subject to the protective conditions and restrictions of any outstanding
Preferred Stock, any amendment to this Restated Certificate of Incorporation
which increases or decreases the authorized capital stock of any class or
classes may be adopted by the affirmative vote of the holders of a majority of
the outstanding shares of the voting stock of the Corporation.

                               Board of Directors

1. Powers of the Board.

  In furtherance and not in limitation of the powers conferred by statute, the
Board of Directors is expressly authorized:

    (a)  To make, alter or repeal the by-laws of the Corporation.

    (b)  To authorize and cause to be executed mortgages and liens upon the real
  and personal property of the Corporation.

    (c)  To set apart out of any of the funds of the Corporation available for
  dividends a reserve or reserves for any proper purpose and to abolish any
  reserve in the manner in which it was created.

    (d)  By a majority of the whole board, to designate one or more committees,
  each committee to consist of one or more of the directors of the Corporation. 
  The Board may designate one or more directors as alternate members of any
  committee, who may replace any absent or disqualified member at any meeting of
  the committee.  The by-laws may provide that in the absence or
  disqualification of a member of a committee, the member or members thereof
  present at any meeting and not disqualified from voting, whether or not he or
  they constitute a quorum, may unanimously appoint another member of the Board
  of Directors to act at the meeting in the place of any such absent or
  disqualified member.  Any such committee, to the extent provided in the
  resolution of the Board of Directors, or in the by-laws of the Corporation,
  shall have and may exercise all the powers and authority of the Board of
  Directors in the management of the business and affairs of the Corporation and
  may authorize the seal of the Corporation to be affixed to all papers which
  may require it; but no such committee shall have the power or authority in
  reference to amending the Restated Certificate of Incorporation, adopting an
  agreement of merger or consolidation, recommending to the stockholders the
  sale, lease or exchange of all or substantially all of the Corporation's
  property and assets, recommending to the stockholders a dissolution of the
  Corporation or a revocation of a dissolution, or amending the by-laws of the
  Corporation; and, unless the resolution or by-laws expressly so provide, no
  such committee shall have the power or authority to declare a dividend or to
  authorize the issuance of stock.

    (e)  When and as authorized by the stockholders in accordance with statute,
  to sell, lease or exchange all or substantially all of the property and assets
  of the Corporation, including its good will and its corporate franchises, upon
  such terms and conditions and for such consideration, which may consist in
  whole or in part of money or property including shares of stock in, and/or
  other securities of, any other corporation or corporations, as the Board of
  Directors shall deem expedient and for the best interests of the Corporation.

2. Terms and Number of Board Members.


                                      -75-

<PAGE>
 
  The number of members of the Board of Directors will be fixed from time to
time by the Board of Directors, but (subject to vacancies) in no event may there
be less than three directors. Each director shall serve until the next annual
meeting of stockholders or until his successor is elected.

  If any vacancy occurs in the Board of Directors during a term, the remaining
directors, by affirmative vote of a majority thereof, may elect a director to
fill the vacancy until the next annual meeting of stockholders.

3. Cumulative Voting.

  At all elections of directors of the Corporation, each stockholder entitled
generally to vote for the election of directors shall be entitled to as many
votes as shall equal the number of votes which (except for this provision as to
cumulative voting) he would be entitled to cast for the election of directors
with respect to his shares of stock multiplied by the number of directors to be
elected, and he may cast all of such votes for a single director or may
distribute them among the number to be voted for, or for any two or more of them
as he may see fit.

                                 ARTICLE SIXTH

                                    Records

  The books of the Corporation may be kept (subject to any provisions contained
in the statutes) outside the State of Delaware at such place or places as may be
designated from time to time by the Board of Directors or in the by-laws of the
Corporation.  Elections of directors need not be by written ballot unless the
by-laws of the Corporation shall so provide.

                                ARTICLE SEVENTH

                               Certain Contracts

  No contract or transaction between the Corporation and one or more of its
directors or officers, or between the Corporation and any other corporation,
partnership, association, or other organization in which one or more of its
directors or officers are directors or officers, or have a financial interest,
shall be void or voidable solely for this reason, or solely because the director
or officer is present at or participates in the meeting of the board or
committee thereof which authorizes the contract or transaction, or solely
because his or their votes are counted for such purpose, if:

    1. The material facts as to his interest and as to the contract or
  transaction are disclosed or are known to the Board of Directors or the
  committee, and the Board of Directors or committee in good faith authorizes
  the contract or transaction by a vote sufficient for such purpose without
  counting the vote of the interested director or directors; or

    2. The material facts as to his interest and as to the contract or
  transaction are disclosed or are known to the stockholders entitled to vote
  thereon, and the contract or transaction is specifically approved in good
  faith by vote of the stockholders; or


                                      -76-

<PAGE>
 
    3. The contract or transaction is fair as to the Corporation as of the time
  it is authorized, approved or ratified, by the Board of Directors, a committee
  thereof, or the stockholders.

Interested directors may be counted in determining the presence of a quorum at a
meeting of the Board of Directors or of a committee which authorizes the
contract or transaction.

                                 ARTICLE EIGHTH

                                Indemnification


1. Claim Brought by Third Parties.

  The Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the Corporation) by reason of the
fact that he is or was or has agreed to become a director or officer of the
Corporation, or is or was serving or has agreed to serve at the request of the
Corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, or by reason of any action alleged to have
been taken or omitted by such person in such capacity, against costs, charges
and other expenses (including attorneys' fees) ("Expenses"), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

2. Claim By or in the Right of the Corporation.

  The Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he is or was or has agreed to become a director or
officer of the Corporation, or is or was serving or has agreed to serve at the
request of the Corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or by reason of any
action alleged to have been taken or omitted by such person in such capacity,
against Expenses actually and reasonably incurred by him in connection with the
investigation, defense or settlement of such action or suit if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Corporation and except that no indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery of the State of Delaware or the court in which such action or
suit was brought shall determine upon application that, despite the adjudication
of liability 


                                      -77-

<PAGE>
 
but in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such Expenses which the Court of Chancery
of the State of Delaware or such other court shall deem proper.

3. Additional Indemnification.

  In addition to the indemnification provided for in paragraphs 1 and 2 of this
Article Eighth, the Corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of another corporation, partnership, join
venture, trust or other enterprise by reason of the fact that he is or was
serving or has agreed to serve at the request of the Corporation as a director
of such other corporation, partnership, joint venture, trust or other enterprise
against Expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding
for breach of fiduciary duty as such director, except for liability:  (i) for
breach of the duty of loyalty to such other corporation, partnership, joint
venture, trust or other enterprise; (ii) for acts or omissions not in good faith
or which involve intentional misconduct or knowing violation of law; (iii) for
unlawful payment of a dividend or unlawful purchase or redemption of stock; or
(iv) for any transaction from which the director derived an improper personal
benefit.

4. Successful Defense.

  To the extent that any person referred to in paragraphs 1, 2 or 3 of this
Article Eighth has been successful on the merits or otherwise, including,
without limitation, the dismissal of an action without prejudice, in defense of
any action, suit or proceeding referred to therein or in defense of any claim,
issue or matter therein, he shall be indemnified against Expenses actually and
reasonably incurred by him in connection therewith.

5. Determination of Conduct.

  Any indemnification under paragraphs 1, 2 or 3 of this Article Eighth (unless
ordered by a court) shall be made by the Corporation only as authorized in the
specific case upon a determination that indemnification of the director or
officer is proper in the circumstances because he has met the applicable
standard of conduct set forth in said paragraphs 1, 2 or 3 of this Article
Eighth.  Such determination shall be made (a) by the board of directors by a
majority vote of a quorum consisting of directors who were not parties to such
action, suit or proceeding, or (b) if such quorum is not obtainable, or, even if
obtainable and a quorum of disinterested directors so directs, by independent
legal counsel in a written opinion, or (c) by the stockholders.

6. Advance Payment.

  Expenses incurred by any person referred to in paragraphs 1, 2 or 3 of this
Article Eighth in defending a civil or criminal action, suit or proceeding shall
be paid by the Corporation in advance of the final disposition of such action,
suit or proceeding upon receipt of an undertaking by or on behalf of such person
to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation as provided in this Article
Eighth.

7. Certificate of Incorporation Article Not Exclusive; Change in Law.


                                      -78-

<PAGE>
 
  The indemnification and advancement of Expenses provided by, or granted
pursuant to, this Article Eighth shall not be deemed exclusive of any other
rights to which those seeking indemnification or advancement of Expenses may be
entitled under any law (common or statutory), by-law, agreement, vote of
stockholders or disinterested directors, or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director or
officer and shall inure to the benefit of the heirs, executors and
administrators of such a person.  Notwithstanding the provisions of this Article
Eighth, the Corporation shall indemnify and make advancement of Expenses to any
person referred to in paragraphs 1, 2 or 3 of this Article Eighth to the fullest
extent permitted under the laws of the State of Delaware and any other
applicable laws, as they now exist or as they may be amended in the future.

8. Contract Rights.

  All rights to indemnification and advancement of Expenses provided by this
Article Eighth shall be deemed to be a contract between the Corporation and each
person referred to in paragraphs 1, 2 or 3 of this Article Eighth.  Any repeal
or modification of this Article Eighth or any repeal or modification of relevant
provisions of the Delaware General Corporation Law or any other applicable law
shall not in any way diminish any rights to indemnification or advancement of
Expenses with respect to any state of facts then or previously existing or any
action, suit or proceeding previously or thereafter brought or threatened based
in whole or in part on such state of facts.

9. Insurance.

  The Corporation shall have power to purchase and maintain insurance on behalf
of any person referred to in paragraphs 1, 2 or 3 of this Article Eighth against
any liability asserted against him and incurred by him in any such capacity, or
arising out of his status as such, whether or not the Corporation would have the
power to indemnify him against such liability under the provisions of this
Article Eighth or of Section 145 of the Delaware General Corporation Law.

10.  Indemnification of Employees or Agents.

  The Board of Directors may, by resolution, extend the indemnification and
advancement of Expenses provisions of this Article Eighth to any person who was
or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding by reason of the fact that he is or was or
has agreed to become an employee or agent of the Corporation, or is or was
serving or has agreed to serve at the request of the Corporation as an employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise.

11.  Definition of Corporation.

  For purposes of this Article Eighth, references to the "Corporation" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, employees or agents so that any
person who is or was or has agreed to become a director, officer, employee or
agent of such constituent corporation, or is or was serving or has agreed to
serve at the request of such constituent 


                                      -79-

<PAGE>
 
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under the provisions of this Article Eighth with respect to the
resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.

12.  Employee Benefit Plans.

  For purposes of this Article Eighth, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the Corporation" shall include any
service as a director or officer of the Corporation which imposes duties on, or
involves services by, such director or officer with respect to an employee
benefit plan, its participants, or beneficiaries; and a person who acted in good
faith and in a manner he reasonably believed to be in the interest of the
participants and beneficiaries of an employee benefit plan shall be deemed to
have acted in a manner "not opposed to the best interest of the Corporation" as
referred to in this Article Eighth.

                                 ARTICLE NINTH

                         Stockholder Action by Consent

  Any corporate action upon which a vote of stockholders is required or
permitted may be taken without a meeting or vote of stockholders with the
written consent of stockholders having not less than a majority of all of the
stock entitled to vote upon the action if a meeting were held; provided, that in
no case shall the written consent be by holders having less than the minimum
percent of the vote required by statute for the proposed corporate action and
provided that prompt notice be given to all stockholders of the taking of
corporate action without a meeting and by less than unanimous written consent.

                                 ARTICLE TENTH

                                   Amendment

  The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Restated Certificate of Incorporation, in the manner
now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

                                ARTICLE ELEVENTH

                         Limited Liability of Directors

  No person who was or is a director of the Corporation shall be personally
liable to the Corporation or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for liability (i) for breach of the duty of
loyalty to the Corporation or its stockholders; (ii) for acts or omissions not
in good faith or which involve intentional misconduct or knowing violation of
law; (iii) under Section 174 of the Delaware General Corporation Law; or (iv)
for any transaction from which the director derived an improper personal
benefit.  For purposes hereof, "fiduciary duty as a director" shall include
fiduciary duties arising in serving at the request of the Corporation as 


                                      -80-

<PAGE>
 
a director of another corporation, partnership, joint venture, trust or other
enterprise, and "personally liable to the Corporation" shall include liabilities
to such other corporations, partnerships, joint ventures, trusts or other
enterprises, and liabilities to the Corporation in its capacity as a security
holder, joint venturer, partner, beneficiary, creditor or investor of or in any
such other corporation, partnership, joint venture, trust or other enterprise.

                2 years but less than 3                    20%

      group of corporations or was under common control with the Bank within the
      meaning of Section 414(b, c, m) of the Internal Revenue Code, as amended,
      which employer had not adopted the Thrift Plan, the Participant's Years of
      Service in the Thrift Plan shall be computed as if the Participant had
      been an employee of the Bank during that period.

                (ii) on sick and/or disability leave, until the first
                anniversary of the commencement of the leave,

           provided he or she resumed permanent employment with the Bank upon
           termination of such absence or leave, or

           (d) for purposes of Sections 2.22 (vesting) and 3 (participation)
           only, absent from service with the Bank for any reason other than a
           quit, discharge or retirement, (e.g., for reason of disability), for
           a period which begins on the date the Employee separates from service
           and ends on the earlier of

                (i) the date on which the Employee subsequently quits, is
                discharged, retires or dies, or

                (ii) the first anniversary of the date on which the Employee
                separates from service,

           and the Employee does not resume permanent employment with the Bank.

      Any service qualifying under any two or more of the foregoing categories
      shall be counted only once.

  SECTION 3.  PARTICIPATION.
              ------------- 

      3.1 Participation.  An Employee shall become a Participant upon the first
      day of the calendar quarter falling after the day on which he or she has
      completed one Year of Service with the Bank or has attained the age of 21
      years, whichever is later.  (For example, if an Employee over age 21
      commences employment with the Bank on July 1, 1993, he or she completes
      one Year of Service with the Bank on July 1, 1994, and becomes a
      Participant in the Thrift Plan on October 1, 1994.)  An Employee who had
      been employed by a related employer while that employer was a member of a
      controlled group of corporations or was under common control with the Bank
      within the meaning of Section 414(b,c,m) of the Internal Revenue Code, as
      amended, shall be considered to have been an employee of the Bank during
      that period for purposes of determining whether he or she has completed
      one Year of Service with the Bank.

           By written notice delivered to the Committee on or before the
      fifteenth day of the preceding month, the Employee shall make an election
      as to Investment Funds in the manner provided in Section 6.3.  In the
      event of the failure of the Employee to make such an election, all
      deposits and contributions for his or her account shall be invested in the
      Short Term Fund.

           An Employee who is a highly compensated employee may agree with the
      Bank in writing that the Employee shall not participate in the Thrift
      Plan.

      3.2 Beneficiary Designation.  At the time of becoming a Participant,
      subject to Section 2.6 an Employee shall designate a Beneficiary to
      receive any benefit payable under the provisions of Section 8.2.  At any
      time and from time to time thereafter the Participant may change or revoke
      the Beneficiary designation.  No designation, revocation or change shall
      be effective unless made in writing and delivered to the Committee prior
      to the Participant's death.

      3.3 Termination of Participation.  Participation in the Thrift Plan shall
      terminate upon the first to occur of:

           (a) The Valuation Date coinciding with or next following the date of
           a Participant's retirement.

                                      -7-
<PAGE>

           (b) The Valuation Date falling immediately after the date the
           Participant terminates his or her service with the Bank by reason of
           permanent disability, as determined by the Committee, provided that
           he or she has not returned to service with the Bank prior to such
           Valuation Date.

           (c) The Valuation Date falling immediately after the date on which
           the Committee receives written notice that a Participant has
           separated from service (other than by retirement or by reason of
           becoming permanently disabled) and no longer receives Salary from the
           Bank; except that

                (i) A Participant who is separated from service by reason of
                transfer to a related employer which is a member of a controlled
                group of corporations or is under common control with the Bank
                within the meaning of Internal Revenue Code Section 414(b,c,m),
                which employer has not adopted the Thrift Plan, shall continue
                his or her participation.  The Participant may make no deposits
                to his or her Deposit Accounts and the Bank shall make no
                contributions to his or her Bank Contribution Account unless and
                until the Participant is reemployed by the Bank or the related
                employer adopts the Thrift Plan.  Such a Participant's
                participation shall terminate upon the first to occur of his or
                her death or separation from service of such a related employer
                without reemployment by the Bank.

                (ii) An alien Participant who is separated from service by
                reason of transfer to any office or branch of the Bank located
                in a foreign country may elect to continue his or her
                participation. The Participant may make no deposits to his or
                her Deposit Accounts and the Bank shall make no contributions to
                his or her Bank Contribution Account unless and until the
                Participant is reemployed by the Bank at an office or branch
                located in the United States.  Such a Participant's
                participation shall terminate upon the first to occur of his or
                her death, separation from service of the Bank or any office or
                branch thereof or related employer, or his or her election to
                terminate such participation.

                (d) The Valuation Date falling immediately after the date on
                which the Committee receives written notice of a Participant's
                death.

      3.4 Reemployment; Restoration of Forfeitures.
          ---------------------------------------- 

          (a) The participation of an Employee whose prior participation in the
          Thrift Plan terminated for any of the reasons specified in paragraphs
          (a), (b) or (c) of Section 3.3 shall be renewed as of the first day
          of the Valuation Period in which the Employee is reemployed.

          (b) By written notice to the Committee after his or her reemployment,
          an Employee who has not had five consecutive One-Year Periods of
          Severance may deposit with the Trustee an amount which shall be equal
          to the aggregate value of the distributions from his or her Deposit
          Accounts and Bank Contribution Accounts at the time of his or her
          previous termination of participation.  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.

               The Trustee shall allocate an Employee's deposits made to
          satisfy the requirements of this Section 3.4(b) as follows:

                (i) An Employee's deposits which are rollover deposits under
                Section 4.1 shall be allocated to the Employee's Rollover
                Deposit Account.

                (ii) All other deposits shall be allocated to the Employee's
                After-Tax Deposit Account.

          (c) In the case of a reemployed Employee who does not have five
          consecutive One-Year Periods of Severance, the Bank shall contribute
          to the Bank Matching Contribution 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 Section 3.4(b) or the Employee did not receive a distribution
          at or after the time of his or her previous termination of service.
          The Bank's contribution shall be made concurrently with the
          Employee's repayment if applicable, otherwise upon the date of his or
          her reemployment.

                                      -9-
<PAGE>

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


  SECTION 4.  PARTICIPANT'S DEPOSITS.
              ---------------------- 

      4.1 Participant's Deposits.  By written notice delivered to the Committee
      on or before the fifteenth day of the month preceding the Valuation Period
      as of which an Employee becomes a Participant, or upon reemployment of a
      former Employee whose participation in this Thrift Plan is renewed
      pursuant to Section 3.4 or is commenced pursuant to Section 3.1, the
      Employee may authorize the Bank to deduct an amount of money from his or
      her Salary and deposit it with the Trustee for investment as he or she
      shall have directed as provided in Section 6.3.  The amount must equal 1%
      of the Employee's Salary or any multiple thereof not exceeding 12%.  The
      amount shall be deposited to the Employee's After-Tax Deposit Account or
      to his or her Before-Tax Deposit Account, or partly to each in whole
      percentages, as designated by the Employee.  Deposits to an Employee's
      Before-Tax Deposit Account in a calendar year may not exceed $7,000,
      adjusted for increases in the cost of living as provided in Internal
      Revenue Code Section 415(d), and any excess deposits shall be made to his
      or her After-Tax Deposit Account.

           Amounts deposited to the Employee's Before-Tax Deposit Account
      pursuant to this Section 4.1 shall be considered as contributions made by
      the Bank on behalf of the Employee to the Thrift Trust under a qualified
      cash or deferred arrangement as defined in Section 401(k)(2) of the
      Internal Revenue Code of 1986 so that the amounts will not be included in
      the Employee's income for federal income tax purposes in the year of
      contribution.  Amounts deposited to the Employee's After-Tax Deposit
      Account shall be considered as deposits made by the Employee from his or
      her Salary which is subject to federal income tax in the year paid.

           With authorization by the Committee, an Employee may make a rollover
      deposit to the Thrift Plan from a qualified plan, an employee annuity, an
      individual retirement account or an individual retirement annuity, as
      described in Sections 402(a)(5), 403(a)(4) and 408(d)(3) of the Internal
      Revenue Code of 1986.  The amount shall be deposited in cash to the
      Employee's Rollover Deposit Account.  An Employee who is not otherwise a
      Participant in the Thrift Plan shall be considered as a Participant solely
      for purposes of his

                                     -10-
<PAGE>

      or her Rollover Deposit Account.  The Committee shall authorize and
      regulate the making of rollover deposits in accordance with uniform and
      nondiscriminatory rules.

      4.2 Changing Rate of Deposits.  A Participant may terminate, authorize or
      change the rate of his or her deposits as of the first day of any
      subsequent Valuation Period by giving notice of the desired change to the
      Committee at least five business days prior to the end of the preceding
      month.  Any new or changed rate shall comply with the requirements of
      Section 4.1.  Changes may be made no more than six times in a calendar
      year, and notice of a change shall be in such form (e.g., by telephone, in
      writing) as the Committee shall determine.

      4.3 Limitations on Deposits.  The Committee in its discretion may at any
      time and from time to time by administrative action limit the percentage
      amount which Participants who are highly compensated employees may elect
      to have contributed to their Before-Tax Deposit Accounts under Section
      4.1, in order to insure that the Thrift Plan will satisfy the requirements
      for a qualified cash or deferred arrangement under Section 401(k) of the
      Internal Revenue Code of 1986.  Limitations may be imposed before the Plan
      in fact violates those requirements.  The term "highly compensated
      employee" shall be defined as provided in Section 401(k)(4) of the Code,
      and the Committee may enumerate the Participants in that category by job
      grade or other reasonable classification.

           The Committee may at any time and from time to time limit the
      percentage amount which all Participants may elect to have contributed to
      their Before-Tax Deposit Accounts under Section 4.1 in order to satisfy
      the requirements of Section 5.5.

           The Committee shall give written notice of limitations or changes in
      limitations under this Section 4.3 to all Participants who are affected
      thereby.

  SECTION 5.  BANK CONTRIBUTIONS.
              -------------------

      5.1 Bank Contingent Matching Contribution.  If an Employee is a
      Participant in the Thrift Plan during any part of a calendar year and, on
      December 31 of that calendar year, is either

           (a) In the service of the Bank or receiving Salary or on leave of
           absence, paid or unpaid, or

                                     -11-
<PAGE>

           (b)   Not in the service of the Bank, but the Employee terminated his
           or her service with the Bank during the calendar year by reason of
           disability, death, normal or early retirement under The Northern
           Trust Company Pension Plan, or any other retirement after his or her
           Normal Retirement Date,

      then the Employee is eligible to have the Bank make a contingent
      contribution to the Employee's Bank Matching Contribution Account for that
      calendar year.  Subject to the provisions of Sections 5.2, 5.4 and 5.5,
      the amount of the contingent contribution for a calendar year shall be the
      applicable percentage of the maximum possible contribution, determined in
      accordance with the following two tables:

<TABLE>

                    4%                             5.0%
</TABLE> 

      "Matchable participant deposits" means the percent of Salary deposited by
      a Participant in the aggregate to his or her After-Tax Deposit Account and
      Before-Tax Deposit Account during the calendar year which is matchable by
      the Bank.  The percent of Salary is determined for each pay period in the
      calendar year, with no percentage exceeding 4%, and the average of the
      percentages for the calendar year is then calculated.  The percent of
      Salary for the calendar year includes not only whole percentages but also
      fractions thereof, which shall be considered by extrapolation in
      determining the maximum possible Bank contribution.

           The applicable percentage of the maximum possible contribution for a
      calendar year shall be determined by how close Northern Trust Corporation
      comes to attaining the earnings goal for the Corporation for the calendar
      year.  The earnings goal for the calendar

                                     -12-
<PAGE>

      year shall be announced by the Bank's Board of Directors in the first
      quarter of the calendar year.  The Corporation's earnings for the calendar
      year for purposes of the Bank's contingent contribution shall be
      determined by the Bank's Board of Directors in its discretion, taking into
      consideration such factors and circumstances and including or excluding
      such items of income and expense as it deems appropriate, and shall be
      announced to Participants in the first quarter of the following year. 
      After the end of the calendar year,

                (i) the Corporation's earnings for the calendar year shall be
                expressed as a percentage of the earnings goal for the year, and

                (ii) the Bank shall make a contingent contribution to the Bank
                Matching Contribution Account of a Participant or former
                Participant in accordance with the following Table Two:

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

          (a) Notwithstanding anything contained herein to the contrary, a
          Participant's annual additions for a calendar year shall not exceed
          the lesser of

                (i) $30,000, adjusted for increases in the cost of living as
                provided in Internal Revenue Code Section 415(d), or

                                     -14-
<PAGE>

                (ii) 25 percent of the Participant's compensation as defined in
                Treasury Regulation Section 1.415-2(d).

          (b) In addition, a Participant's annual additions for a calendar year
          shall not exceed an amount which would produce a defined contribution
          plan fraction which, when added to the Participant's defined benefit
          plan fraction (after reduction of the Participant's Pension as
          provided in the Bank's Pension Plan, except as may be otherwise
          provided by an instrument in writing filed with the Committee as
          provided in the Bank's Pension Plan), would produce a combined
          fraction of more than 1.0.

               A Participant's defined contribution plan fraction for a
          calendar year is a fraction, the numerator of which is the sum of the
          Participant's annual additions for the calendar year and all prior
          calendar years, and the denominator of which is the sum of the lesser
          of the following amounts (determined for the calendar year and for
          each prior calendar year of service with the Bank):  (i) the product
          of 1.25 multiplied by the dollar limitation in effect under Internal
          Revenue Code Section 415(c)(1)(A) for such calendar year, or (ii) the
          product of 1.4 multiplied by 25% of the Participant's compensation
          for such calendar year.

               A Participant's defined benefit plan fraction for a calendar
          year is a fraction, the numerator of which is the Participant's
          projected annual benefit (determined as of the close of the calendar
          year), and the denominator of which is the lesser of (i) the product
          of 1.25 multiplied by the maximum dollar limitation under Internal
          Revenue Code Section 415(b)(1)(A) for that year, or (ii) the product
          of 1.4 multiplied by 100% of the Participant's average compensation
          for his or her high 3 years.  However, the denominator of the
          fraction shall not be less than 1.25 multiplied by the annual benefit
          which the Participant had accrued under the Bank's Pension Plan as of
          September 30, 1983.

               For any calendar year in which the Thrift Plan is a top-heavy
          plan, this Section 5.2(b) shall be administered by substituting "1.0"
          for "1.25."

          (c) A Participant's annual additions are the sum of

                                     -15-
<PAGE>

                (i) a Participant's deposits to his or her After-Tax Deposit
              Account and Before-Tax Deposit Account, and

                (ii) the Bank's contributions to the Participant's Bank
              Matching Contribution Account.

          (d) To the extent a Participant's annual additions for a calendar
          year exceed the limitations in either (a) or (b), the Participant's
          deposits shall be returned to the Participant in the following order:

                (i) The Participant's deposits to his or her After-Tax Deposit
              Account; then

                (ii) The Participant's deposits to his or her Before-Tax
              Deposit Account.

          After giving effect to the foregoing sentence, if appropriate, the
          Bank shall make no contribution to the Participant's Bank Matching
          Contribution Account  which would result in those limitations being
          exceeded.  If any excess annual additions nonetheless remain in the
          Participant's Accounts, such excess amounts shall be subtracted from
          his or her Bank Matching Contribution Account.  The subtracted amount
          shall be used to reduce Bank contributions as provided in Section
          5.4.

               To satisfy the requirements of Internal Revenue Code Section
          415, Participant deposits and Bank contributions to a Participant's
          Accounts in the Thrift Plan shall be reduced before any reduction in
          allocations for a Participant under the Northern Trust Employee Stock
          Ownership Plan.

          (e) In applying the limitations under this Section 5.2, all employers
          which are included in a controlled group of corporations or are under
          common control with the Bank within the meaning of Section 414(b, c,
          m) of the Internal Revenue Code shall, together with the Bank, be
          considered as a single employer.  In addition, in applying these
          limitations, all defined contribution plans (whether or not
          terminated) of the Bank shall be treated as one defined contribution
          plan, and all defined benefit plans (whether or not terminated) of
          the Bank shall be treated as one defined benefit plan.

                                     -16-
<PAGE>

      5.3 Time of Bank Contributions.  The Bank's contingent matching
      contribution for a calendar year on behalf of a Participant shall be made
      as soon as practicable after the end of the calendar year, without
      interest, but otherwise shall be deemed to have been made as of December
      31 of the calendar year if it is made not later than the time prescribed
      by law for the filing of the Bank's federal income tax return for that
      year.  All contributions shall be transmitted to the Trustee for
      investment as the Participant shall have directed as provided in Section
      6.3.

      5.4 Forfeitures.  Forfeitures under Section 8.3 shall be held in a
      suspense account in the Thrift Plan and invested in the Short Term Fund.
      Notwithstanding the provisions of Section 5.1, the forfeitures in the
      suspense account, and the earnings thereon, shall be used first to satisfy
      the Bank Contingent Matching Contribution, and the Bank's contribution
      under Section 5.1 shall be reduced (but not below zero) accordingly.

      5.5 Limitations on Contributions.  Contributions by any corporation which
      is a party to this Thrift Plan shall be made only on behalf of
      Participants who are Employees of the contributing corporation and such
      contributions shall be made only from current or accumulated earnings of
      such corporation, provided, however, that if any such corporation is
      prevented from making a contribution which it would otherwise have made
      under the Thrift Plan by reason of having no current or accumulated
      earnings or because such earnings are less than the contributions which it
      would otherwise have made, then so much of the contribution which such
      corporation was so prevented from making may be made for the benefit of
      the Participants who are Employees of such corporation by any of the other
      corporations which are parties to this Thrift Plan to the extent of
      current or accumulated earnings, except that if the corporations which are
      parties to this Thrift Plan do not file a consolidated Federal income tax
      return, such contribution by each such other corporation shall be limited
      to that proportion of its total current and accumulated earnings,
      remaining after adjustment for its contributions on behalf of Participants
      who are its own Employees, which the total prevented contribution bears to
      the total current and accumulated earnings of all such corporations
      remaining after adjustment for all contributions on behalf of Participants
      who are their own Employees.  The amount of contributions made by any
      corporation which is a party to this Thrift Plan shall not exceed the
      amount deemed to be deductible in computing the taxable income of such
      corporation (taking into account all contributions under The Northern
      Trust Company Pension Plan and all privileges and limitations of carry
      over and carry forward as established by law) for the purpose of computing
      taxes on, or measured by, income under the provisions of the

                                     -17-
<PAGE>

      Internal Revenue Code or any other laws in effect from time to time.

      5.6 Top-Heavy Rules.  The following provisions shall become effective in
      any plan year after 1983 in which the Thrift Plan is determined to be a
      top-heavy plan.

           (a) Determination of Top-Heavy.  The Thrift 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 Internal Revenue
           Code) exceeds 60% of the account balances of all Participants (the
           "60% 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% 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 Bank in which a key employee is
           a participant and each other plan of the Bank, if any, which enables
           such plan to meet the requirements of Internal Revenue Code Section
           401(a)(4) or 410.  The Bank 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 Internal Revenue Code Sections 401(a)(4) and 410 with
           such plan being taken into account.

           (b) Minimum Benefit.  The Bank's contribution to a Participant's Bank
           Matching Contribution Account under Section 5.1 shall be 3 percent of
           the Participant's compensation within the meaning of Section 415 of
           the Internal Revenue Code (i.e., the Participant's total compensation
           as determined for federal wage withholding taxes for form W-2),
           except that this paragraph (b) shall not apply if

                (i) the Participant is also a participant in The Northern Trust
                Company Pension Plan,

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

                                     -18-
<PAGE>

                (iii) the Participant receives from the Pension Plan the defined
                benefit minimum required under Section 416(c)(1) of the Internal
                Revenue Code.

           (c) Minimum Vesting.  A Participant's Vested Portion under Section
           2.20 shall be the percentage of the Participant's Bank Matching
           Contribution Account determined in accordance with the following
           table:

<TABLE> 
<CAPTION> 
           Participant's
           Years of Service
           as defined in
           Internal Revenue
           Code Section 411          Vested Percentage
           ----------------          -----------------
           <S>                       <C>
           2 but less than 3                 20%
           3 but less than 4                 40%
           4 but less than 5                 60%
           5 but less than 6                 80%
           6 or more                        100%
</TABLE> 

           (d) Change in Top-Heavy Status.  If the Thrift Plan becomes a top-
           heavy plan and subsequently ceases to be such, the vesting schedule
           in paragraph (c) of this section shall continue to apply in
           determining the Vested Portion of the Bank Matching Contribution
           Account of any Participant who had at least five years of service as
           of December 31 in the last plan year of top-heaviness.  For other
           Participants, said schedule shall apply only to the amount of their
           Bank Matching Contribution Accounts as of such December 31.

      5.7 Transfers from ESOP.  To enable the Northern Trust Employee Stock
      Ownership Plan to satisfy the investment diversification requirement of
      Internal Revenue Code Section 401(a)(28)(B), the Thrift Plan shall accept
      transfers of property directly from an Employee's account in the Employee
      Stock Ownership Plan which are made to fulfill that requirement.  The
      transferred property shall be added to the Employee's ESOP Contribution
      Account.  The Committee shall regulate the making of transfers in
      accordance with uniform and nondiscriminatory rules.

  SECTION 6.  INVESTMENT FUNDS.
              -----------------

       6.1 Investment Funds.  There shall be the following six Investment Funds:
           ----------------                                                     

           Short Term Fund: This Fund invests primarily in debt instruments with
           short maturity dates (e.g., money market instruments).  This Fund
           shall be invested with the objective of minimizing fluctuations in
           the market value of the Fund, while obtaining maximum income
           consistent with that objective.

           Benchmark Funds - Bond Portfolio: This Fund invests primarily in debt
           instruments with longer maturity dates (e.g. bonds).

           Benchmark Funds - Balanced Portfolio: This Fund invests in stocks,
           bonds and money market instruments.  The mix of these investments is
           continually monitored and adjusted.

           Benchmark Funds - Equity Index Portfolio: This Fund invests primarily
           in common stocks.  The Fund seeks to achieve investment performance
           results paralleling the results of the Standard & Poors 500 Stock
           Index.  The Fund's investments are not actively managed.

           Benchmark Funds - Focused Growth Portfolio: This Fund invests
           primarily in stocks of companies with high growth potential.

           Northern Trust Stock Fund: This Fund shall be invested primarily in
           shares of common stock of Northern Trust Corporation.

      The Benchmark Fund is a registered investment company.  The Northern Trust
      Company is the investment adviser, transfer agent and custodian for each
      portfolio of the Fund, and it receives from each portfolio a fee for its
      services.

      6.2 Administration of Funds.  Each of the Investment Funds shall be
      invested without distinction between principal and income.  Pending
      payment of costs, expenses and anticipated benefits, or acquisition of
      permanent investments, the Trustee may hold any portion of any of the
      Investment Funds in money market instruments (or in a collective

                                     -20-
<PAGE>

      investment fund or registered investment company composed primarily of
      such investments).  To facilitate administration of the Thrift Plan, the
      Committee may allocate the aggregate deposits and contributions on behalf
      of all Participants among the Investment Funds on an estimated basis
      during a Valuation Period and make compensating adjustments among the
      Funds, if needed, as of the end of the Valuation Period.

      6.3 Selection of Investment Funds.  Each Participant shall have the right
      to direct that:

            (i) the Participant's deposits to his or her After-Tax Deposit
          Account and to his or her Before-Tax Deposit Account shall be invested
          in specified multiples of 1% in any one or more of the Investment
          Funds (but not in the Northern Trust Stock Fund), with the same
          election applying to deposits to both Accounts,

            (ii) the Participant's deposits to his or her Rollover Deposit
          Account shall be invested in specified multiples of 1% in any one or
          more of the Investment Funds (but not in the Northern Trust Stock
          Fund),

            (iii) contributions by the Bank to the Participant's Bank Matching
          Contribution Account shall be invested in specified multiples of 1% in
          any one or more of the Investment Funds, and

            (iv) transfers to the Participant's ESOP Contribution Account shall
          be invested in specified multiples of 1% in any one or more of the
          Investment Funds.

      Any such direction must be received by the Committee at least five
      business days prior to the end of  a Valuation Period.  Directions under
      paragraphs (i) and (iii) shall become effective as of the first day of the
      next Valuation Period and shall apply only to deposits and contributions
      made after such effective date.  Directions under paragraphs (ii) and (iv)
      shall become effective as of the next Valuation Date.  Directions shall be
      in such form (e.g., by telephone, in writing) as the Committee shall
      determine.  Transfers may be made no more than six times in a calendar
      year.

      6.4 Transfers Between Funds.  Each Participant shall have the right to
      direct that:

            (i) his or her After-Tax Deposit Account and Before-Tax Deposit
          Account and Rollover Deposit Account which are invested in any one or
          more of the Investment

                                     -21-
<PAGE>

          Funds, shall be transferred in whole or in part to any one or more of
          the Investment Funds (but not the Northern Trust Stock Fund), with the
          same election applying to transfers in all three Accounts, and

            (ii) his or her Bank Basic Contribution Account and Bank Matching
          Contribution Account and ESOP Contribution Account which are invested
          in any one or more of the Investment Funds, shall be transferred in
          whole or in part to any one or more of the Investment Funds, with the
          same election applying to transfers in all three Accounts.

      Any such direction must be received by the Committee at least five
      business days prior to the end of a Valuation Period and shall become
      effective as of the next Valuation Date.  Directions shall be in such form
      (e.g., by telephone, in writing) as the Committee shall determine.
      Transfers may be made no more than six times in a calendar year.

      The Committee in its discretion may at any time and from time to time
      regulate, limit or prohibit Participants from making transfers to or from
      (or investing in, or withdrawing or borrowing from) the Northern Trust
      Stock Fund under this Thrift Plan, in order to ensure that federal
      securities laws will not be violated currently or in the future.

     6.5. Voting Rights; Tender Offers.
          -----------------------------

            (a) Each Participant having an interest in the Northern Trust Stock
          Fund shall have the right to direct the manner in which the Trustee
          shall vote common stock of Northern Trust Corporation ("Company
          Stock") in such Fund equivalent to his or her Proportionate Interest
          therein.

            (b) In the event of a Tender Offer for Company Stock, each
          Participant having an interest in the Northern Trust Stock Fund shall
          have the right to direct whether the Trustee will (i) tender Company
          Stock in such Fund equivalent to his or her Proportionate Interest
          therein and (ii) withdraw such Stock from the depository into which it
          is tendered pursuant to such direction.

            (c) Subject to Sections 11.6, 11.7 and 14 of the Plan and Part 4 of
          Title I of ERISA, the Trustee shall vote, tender, or withdraw from the
          depository into which tendered, Company Stock in the Northern Trust
          Stock Fund only in accordance

                                     -22-
<PAGE>

          with directions received from Participants within the time periods set
          forth below and shall not vote, tender, or so withdraw Company Stock
          in the Northern Trust Stock Fund equivalent to the Proportionate
          Interest of Participants from whom timely directions are not received
          by the Trustee pursuant to this Section.

            (d) As soon as possible prior to each stockholders meeting of
          Northern Trust Corporation, the Trustee shall provide each Participant
          entitled under this Section to direct the voting of Company Stock with
          notice of such meeting and of those matters which at the time of the
          mailing of such notice are expected to be presented at such meeting
          for action by holders of Company Stock.  Such notice shall be
          accompanied by an appropriate form with which the Participant may
          direct the manner of voting on such matters.  If directions on such
          matters are received by the Trustee from any such Participant at least
          two (2) days prior to such meeting, the Trustee shall vote such
          Participant's Proportionate Interest in accordance with the directions
          received from such Participant.

            (e) If any person makes a Tender Offer for shares of Company Stock
          which includes shares of Company Stock held in the Northern Trust
          Stock Fund, the Trustee shall promptly notify each Participant having
          an interest in the Northern Trust Stock Fund:  (i) that a Tender Offer
          for shares of Company Stock has been commenced, (ii) of the identity
          of the tender offer or, (iii) of such other information as the Trustee
          deems appropriate to enable the Participant to make an independent
          decision with respect to the tendering of such Stock, (iv) that the
          Participant has the right to direct whether his Proportionate Interest
          will be tendered and (v) that Company Stock constituting the
          Participant's Proportionate Interest will not be tendered except to
          the extent that a direction to tender has been received by the Trustee
          from such Participant no later than the date two (2) days before the
          deadline for tenders under such Tender Offer.  Such notice will be
          accompanied by an appropriate form with which the Participant may
          direct the Trustee whether to tender his Proportionate Interest.  If
          such written direction is received by the Trustee prior to such date,
          the Trustee shall tender, or not tender, such Participant's
          Proportionate Interest in accordance with such directions.  A
          Participant's direction to tender or not tender shall become
          irrevocable on the date two (2) days before such deadline for tenders
          and may be revoked by a subsequent direction received by the Trustee
          from such Participant on or before such date.  After shares of Company
          Stock have been tendered pursuant to this Section, the proceeds of the

                                     -23-

          Trust's sale of such Company Stock pursuant to the Tender Offer
          attributable to each Participant who directed the tender of his
          Proportionate Interest shall be separately accounted for in the
          Northern Trust Stock Fund.  As soon as practicable after consummation
          of the sale of such Stock thereunder, the directing Participant's
          interest in the Northern Trust Stock Fund will be debited with the
          proceeds of such sale, and as of the end of the Valuation Period that
          interest shall be transferred to the Short Term Fund.

            (f) If shares of Company Stock have been tendered in a Tender Offer
          by the Trustee pursuant to the direction of a Participant, and if
          withdrawal rights arise pursuant to (i) the terms of such Tender
          Offer, (ii) any statute or regulation promulgated thereunder, or (iii)
          a court order, the Trustee shall promptly notify any Participant who
          made such a direction that he has the right to direct the withdrawal
          of the shares of Company Stock tendered pursuant to his direction from
          the depository into which such shares have been tendered.  The Trustee
          will provide such Participant with an appropriate form with which he
          may direct the Trustee to withdraw such shares.  In the event the
          Trustee receives any such written direction within sufficient time to
          act, it shall withdraw such shares of Company Stock.

          (g) Definitions.
              ------------

              (i) The "Proportionate Interest" of a Participant is the number
              of shares of Company Stock determined by multiplying the total
              number of shares of Company Stock held in the Northern Trust
              Stock Fund by a fraction, the numerator of which is the
              Participant's interest in the Northern Trust Stock Fund and the
              denominator of which is the entire balance of the Northern Trust
              Stock Fund.  All determinations made pursuant to the preceding
              sentence shall be as of the first day of the Valuation Period
              which Period includes (A) in the case of the voting of Company
              Stock, the record date for the applicable meeting, and (B) in
              the case of a Tender Offer for Company Stock, the date on which
              the Tender Offer was announced.

              (ii) A "Tender Offer" is a tender offer for, or a request for or
              invitation for tenders of, stock within the meaning of Section
              14(d) of the  Securities Exchange Act of 1934 and applicable
              rules, regulations and case law thereunder.

      6.6 Individual Accounts.  The Committee will maintain or cause to be
      maintained individual accounts, as defined in Sections 2.1, 2.3, 2.4, 
      2.5, 2.11 and 2.16, of the interests of Participants in the several
      Investment Funds, showing separately interests resulting from the deposits
      of Participants and from contributions made by the Bank on their behalf.
      Each Investment Fund may be invested as a single fund, however, without
      segregation of Fund assets to the individual accounts of Participants.

  SECTION 7:  VALUATION AND ADJUSTMENTS.  As of each Valuation Date, the
              --------------------------                                 
  Committee shall determine on an accrual basis of accounting the value of each
  After-Tax Deposit Account, Before-Tax Deposit Account, Rollover Deposit
  Account, ESOP Contribution Account, Bank Basic Contribution Account, and Bank
  Matching Contribution Account in the following manner:

      7.1 As soon as practicable after each Valuation Date, the Trustee shall
      determine and report to the Committee the fair market value of the assets
      of each of the Investment Funds, determined as of the Valuation Date or
      the next previous business day if the Valuation Date falls on a Saturday,
      Sunday or holiday.

      7.2 With respect to each Investment Fund, the Committee shall determine
      the factor representing the ratio between the fair market value of such
      Fund as of the Valuation Date as reported to the Committee by the Trustee
      and the sum of (1) the adjusted value of the Fund on the next preceding
      Valuation Date determined as provided in Section 7.4 and (2) the aggregate
      amount of all Participants' deposits and loan payments and Bank
      contributions during the Valuation Period beginning after the next
      preceding Valuation Date.  Each After-Tax Deposit Account, Before-Tax
      Deposit Account, Rollover Deposit Account, ESOP Contribution Account, Bank
      Basic Contribution Account and Bank Matching Contribution Account in an
      Investment Fund shall be adjusted by multiplying it by the factor for the
      Fund so determined by the Committee.

      7.3 Following the adjustment of each Account in an Investment Fund
      pursuant to Section 7.2, the Committee shall determine the benefits and
      withdrawals distributable, loans granted and amounts transferable as of
      the Valuation Date from the Fund and shall direct the Trustee to pay such
      benefits, withdrawals and loans to the Participants and Beneficiaries
      entitled thereto and deposit such amounts transferable to other Investment
      Funds in such Funds.

                                     -25-
<PAGE>

      7.4 The Committee shall deduct the amount of benefits and withdrawals
      distributed, loans disbursed and amounts transferred from each Investment
      Fund as of the Valuation Date from, and add the amount of transfers to
      such Fund as of the Valuation Date to, the fair market value of such Fund
      as of the Valuation Date as reported to the Committee by the Trustee, and
      the resulting figure shall be recorded on the Committee's books as the
      adjusted value of such Investment Fund on the Valuation Date.

  SECTION 8. BENEFITS.
             --------- 

      8.1 Normal Retirement Date, Pension, Disability.  Each Participant whose
      participation in the Thrift Plan terminates by reason of termination of
      service with the Bank

          Retirement Date, or

            (b) after the Participant has qualified for an Early Retirement
          Pension under The Northern Trust Company Pension Plan, or

      contribution for the calendar year in which his or her participation
      terminates as provided in Section 5.3.

      8.2. Death.  If a Participant dies, his or her Beneficiary, if any, shall

      Account, Rollover Deposit Account, ESOP Contribution Account, Bank Basic
      Contribution Account and Bank Matching Contribution Account in Participant
      loans and in each of the Investment Funds, adjusted as provided in Section
      7.2 as of the Valuation Date upon which his or her participation
      terminates as provided in Section 3.3, and also any Bank contingent
      matching contribution for the calendar year in which his or her

                                     -26-
<PAGE>
 
      Participant may designate a different Beneficiary or Beneficiaries for all
      or a specific portion of the Participant's Deposit and Bank Contribution
      Accounts.  In case there is no Beneficiary designated or in existence at
      the death of such Participant, payment shall be made as follows:

            (a) If a Will of such Participant shall be admitted to probate, then
          as specifically directed in such Will, and in the absence of a
          specific direction, then as the Will shall direct distribution of his
          or her residuary estate.

            (b) In case the Committee shall have no notice that a Will of such
          deceased Participant has been admitted to probate within sixty days
          after his or her death, then to the heirs-at-law of the Participant,
          said heirs-at-law and the proportions they shall respectively be
          entitled to take to be determined according to the laws of descent of
          the State of Illinois in effect at the Participant's death.

      In no event shall any benefit be paid to or through a Participant's estate
      unless the Participant shall specifically so direct.

      8.3 Termination of Service.  Each Participant whose service with the Bank
      terminates for any reason, voluntary or involuntary, other than those
      enumerated in Sections 8.1 and 8.2, shall be entitled to receive a benefit
      equal to the value of the sum of his or her After-Tax Deposit Account,
      Before-Tax Deposit Account, Rollover Deposit Account, ESOP Contribution
      Account, Bank Basic Contribution Account and the Vested Portion of his or
      her Bank Matching Contribution Account in Participant loans and in each of
      the Investment Funds, adjusted as provided in Section 7.2 as of the
      Valuation Date upon which his or her participation terminates as provided
      in Section 3.3.  The Unvested Portion of the Participant's Bank Vesting
      Contribution Account shall be forfeited and disposed of as provided in
      Section 5.4.

      8.4 Restrictions on Mandatory Distributions.  If a Participant who is
      under 65 years of age is entitled to receive a benefit under Section 8.1
      or 8.3, and if the aggregate value of the Participant's Accounts in the
      Thrift Plan is greater than $3,500, the benefit may not be distributed to
      the Participant without his or her written consent delivered to the
      Committee prior to the Valuation Date upon which his or her participation
      terminates.  If the Participant does not so consent, his or her benefit
      shall not be distributed until the Participant requests a total
      distribution, attains 65 years of age or dies.  During that period

                                     -27-
<PAGE>
 
      of time the Participant's benefit shall be treated as are the Accounts of
      continuing Participants, except that (a) no additions to such Accounts may
      be made, (b) such Accounts must be invested solely in the Short Term Fund,
      and (c) the Participant may not exercise the rights granted under Section
      8.5 of the Thrift Plan.

      8.5 Withdrawals.  Subject to the limitations hereinafter in this Section
      8.5 provided, a Participant shall have the right to make a withdrawal as
      of a Valuation Date by setting forth the amount he or she desires to
      withdraw in a notice received by the Committee at least five business days
      prior to the end of the Valuation Period.  To make a withdrawal, the
      Participant must be in the service of the Bank or a related employer when
      the withdrawal is made.

          I.  Withdrawals Over Age 59-1/2.  A Participant who is 59-1/2 years
      of age or older as of a Valuation Date shall be entitled to withdraw as of
      right any part or all of the vested amounts in his or her Thrift Plan
      Accounts listed below, in the order designated:

            (a) After-Tax Deposit Account
            (b) Rollover Deposit Account
            (c) ESOP Contribution Account
            (d) Vested Portion of Bank Matching Contribution Account
            (e) Bank Basic Contribution Account
            (f) Before-Tax Deposit Account

          II.  Withdrawals Under Age 59-1/2.  A Participant who is under 59-1/2
      years of age as of a Valuation Date may make withdrawals from his or her
      Thrift Plan Accounts as follows:

                            Withdrawals as of Right
                            -----------------------

            (a) A Participant shall be entitled to withdraw as of right from his
          or her After-Tax Deposit Account an amount equal to the value of his
          or her After-Tax Deposit Account on such Valuation Date, reduced by
          the aggregate amount of the Participant's deposits to that Account
          which were made during the last twenty four Valuation Periods ending
          on such Valuation Date and which were or could be the basis for
          determining Bank contributions to the Participant's Bank Matching
          Contribution Account.  If a Participant makes deposits to both his or
          her After-Tax

                                     -28-
<PAGE>

          Deposit Account and Before-Tax Deposit Account in a Valuation Period,
          the deposits to the Before-Tax Deposit Account shall be deemed to be
          the basis for Bank contributions before the deposits to the After-Tax
          Deposit Account are so considered.

            (b) A Participant shall be entitled to withdraw as of right from his
          or her Rollover Deposit Account an amount equal to the value of his or
          her Rollover Deposit Account on such Valuation Date.

            (c) A Participant shall be entitled to withdraw as of right from his
          or her ESOP Contribution Account an amount equal to the value of his
          or her ESOP Contribution Account on such Valuation Date.

            (d) A Participant shall be entitled to withdraw as of right from his
          or her Bank Matching Contribution Account an amount equal to the value
          of the Vested Portion of his or her Bank Matching Contribution Account
          as of such Valuation Date, adjusted as provided in Section 7.2 as of
          such Valuation Date.  In no event shall any withdrawal under this
          paragraph 8.5(II)(d) reduce the value of the Participant's Bank
          Matching Contribution Account below the amount of the Bank's
          contributions to such Account during the twenty four Valuation Periods
          ending on such Valuation Date.

                If a Participant has at least five years of participation in the
          Thrift Plan, paragraphs 8.5(II)(a) and 8.5(II)(d) shall be
          administered for that Participant by substituting "twelve Valuation
          Periods" for "twenty four Valuation Periods."


                            Withdrawals for Hardship
                            ------------------------

            (e) Upon proof satisfactory to the Committee of hardship, a
          Participant shall be permitted to withdraw additional vested amounts
          from his or her Thrift Plan Accounts.  Such withdrawals shall be made
          from the following Accounts of a Participant in the order designated:

                     (i) After-Tax Deposit Account

                                     -29-
<PAGE>

                     (ii) Rollover Deposit Account

                     (iii) ESOP Contribution Account

                     (iv) Vested Portion of Bank Matching Contribution Account

                     (v)   Before-Tax Deposit Account, except that a Participant
                           may not withdraw earnings credited to that Account
                           after December 31, 1988.

                Withdrawals on account of hardship may be made only for the
          following financial needs:

                       (I) Medical expenses previously incurred by the
                     Participant or his or her spouse or dependents, or
                     necessary for these persons to obtain medical care,

                       (II) Purchase (excluding mortgage payments) of a
                     principal single family residence of the Participant,

                       (III) Payment of tuition and related educational fees for
                     the next 12 months of post-secondary education for the
                     Participant or his or her spouse, children or dependents,

                       (IV) The need to prevent the eviction of the Participant
                     from his or her principal single family residence or the
                     foreclosure on the mortgage of the Participant's principal
                     single family residence, or

                       (V) Such other financial needs as the Internal Revenue
                     Service may publish in documents of general applicability.

                In addition, withdrawals on account of hardship may not be made
          in excess of the amount required to relieve such financial need or to
          the extent such need may be satisfied from other resources that are
          reasonably available to the Participant.  This determination generally
          is to be made on the basis of all relevant facts and circumstances.
          The Participant's resources shall be deemed to include the assets of

                                     -30-
<PAGE>

          the Participant's spouse and minor children that are reasonably
          available to the Participant.  The amount of such financial need
          includes the amounts necessary to pay income taxes and penalties
          reasonably anticipated to result from the withdrawal.  A withdrawal
          generally may be treated as necessary to satisfy a financial need if
          the Committee relies upon the Participant's written representation,
          unless the Committee has actual knowledge to the contrary, that the
          need cannot reasonably be relieved:

                (1)  Through reimbursement or compensation by insurance or
                     otherwise,

                (2)  By liquidation of the Participant's assets,

                (3)  By cessation of the Participant's deposits under the Thrift
                     Plan, or

                (4)  By other distributions or nontaxable loans from plans
                     maintained by the Bank or any other employer, or by
                     borrowing from commercial sources on reasonable commercial
                     terms.

          A financial need cannot reasonably be relieved by one of these
          actions if the effect would be to increase the amount of the need.

          (f) Amounts withdrawn pursuant to this Section 8.5 (II) shall be
          made first under paragraph (a), then under paragraph (b), then under
          paragraph (c), then under paragraph (d), and last under paragraph (e).

      III. General Rules for Withdrawals.  No withdrawal shall reduce the value
      of a Participant's Account below zero.  Any amount withdrawn from an
      Account of a Participant shall be charged against the Account's investment
      in the Investment Funds in the order designated:

                Short Term Fund

                Benchmark Fund - Bond Portfolio

                Benchmark Fund - Balanced Portfolio

                                     -31-
<PAGE>

                Benchmark Fund - Equity Index Portfolio

                Benchmark Fund - Focused Growth Portfolio

                Lastly, the Northern Trust Stock Fund, subject to the last
                paragraph of Section 6.4

      A Participant may withdraw from his or her Account no more than six times
      in a calendar year.  A Participant's directions for withdrawals shall be
      in such form (e.g., by telephone, in writing) as the Committee shall
      determine.  After calendar year 1993, the minimum amount which a
      Participant may withdraw from his or her Thrift Plan Accounts as of right
      under Section 8.5 (I) and (II) (a-d) is $1,000 per withdrawal, with the
      Accounts being valued as of the preceding Valuation Date.  Amounts
      withdrawn shall be paid to the Participant as soon as reasonably
      practicable after the Valuation Date, without interest.

      8.6 Required Distributions at Age 70-1/2.  A Participant shall commence to
      receive his or her vested interest in the Thrift Plan not later than April
      1 of the year following the calendar year in which he or she attains 70-
      1/2 years of age, even if the Participant has not terminated service with
      the Bank, unless he or she attained age 70-1/2 before January 1, 1988 and
      was not a 5 percent owner of the Bank during the calendar year in which he
      or she attained age 66-1/2 and any subsequent year.  Distributions shall
      be made in accordance with regulations prescribed by the Secretary of the
      Treasury under Internal Revenue Code Section 401(a)(9) over a period not
      extending beyond the life expectancy of the Participant or the life
      expectancy of the Participant and his or her designated Beneficiary.
      Required distributions shall be made in the same order as withdrawals
      under Section 8.5.

      8.7 Loans to Participants.
          ----------------------

          (a) A Participant shall have the right to borrow money from his or
          her Thrift Plan Account as of a Valuation Date by a notice received by
          the Committee at least five business days prior to the end of the
          Valuation Period.  The amount of the loan shall not exceed the lesser
          of

                                     -32-
<PAGE>

                (i)  if the aggregate value of the Participant's After-Tax
                Deposit Account, Before Tax Deposit Account, Rollover Deposit
                Account, ESOP Contribution Account, Bank Basic Contribution
                Account, and the Vested Portion of his or her Bank Matching
                Contribution Account valued as of the prior Valuation Date is
                less than $100,000, one-half thereof, and

                (ii) if the aggregate value of the Participant's vested Accounts
                described in (i) above is $100,000 or more, $50,000

          except that if the Participant has an outstanding balance of loans
          from the Thrift-Incentive Plan, the amount available for any
          additional loan shall be reduced by the lesser of (1) 50% of the
          Participant's vested Accounts described in (i), including the value of
          any outstanding balance of loans from the Thrift-Incentive Plan, minus
          the value of those loan balances or (2) $50,000 minus the highest
          outstanding balance of loans from the Thrift-Incentive Plan during the
          one year period before the date on which such loan was made.

          For purposes of the limitations of this paragraph (a), loans made to
          a Participant from a qualified employer plan maintained by a related
          employer which is a member of a controlled group of corporations or is
          under common control with the Bank within the meaning of Section 414
          (b,c,m) of the Internal Revenue Code of 1986, as amended, shall be
          considered as being made from the Thrift Plan, and all qualified
          employer plans of all such related employers and the Bank shall be
          treated as one plan.

                The minimum amount which a Participant may borrow from his or
          her Thrift Plan Accounts is $1,000 per loan, with larger amounts in
          additional increments of $500.

          (b) A loan shall by its terms be required to be repaid within five
          years unless the loan is used to acquire a single dwelling unit which
          within a reasonable time is to be used (determined at the time the
          loan is made) as the principal residence of the Participant.  A loan
          must be repaid in substantially equal installments on each payday.  A
          Participant may have no more than two loans outstanding at any time.
          A Participant may prepay all of the remaining principal balance of a
          loan at any time, but partial prepayments are not permitted.

                                     -33-

          (c) A loan shall be made on such terms of repayment and interest and
          subject to such rules and restrictions as the Committee shall
          determine, provided that any such loans shall be available to all
          Participants on a reasonably equivalent basis, bear a reasonable rate
          of interest, and be adequately secured.  For purposes of the preceding
          sentence, the term "a reasonable rate of interest" shall mean the
          interest rate which would be charged by The Northern Trust Company for
          a commercial loan secured by a savings account, on the first day of
          each month preceding a Valuation Date.  The loan shall be made as of
          the Valuation Date and shall be disbursed as soon as practicable
          thereafter, and the Participant shall not be obligated to pay (nor be
          entitled to receive) interest on the funds from the Valuation Date to
          the date of disbursement.

          (d) The loan to the Participant shall be made from the Participant's
          Accounts in the following order:

                     (i)   Rollover Deposit Account

                     (ii)  ESOP Contribution Account

                     (iii) Vested Portion of Bank Matching Contribution Account

                     (iv)  After-Tax Deposit Account

                     (v)   Bank Basic Contribution Account

                     (vi)  Before-Tax Deposit Account.

          Any loan from an Account shall be charged against the Account's
          investment in the Investment Funds in the order designated:

                     Short Term Fund

                     Benchmark Fund - Bond Portfolio

                     Benchmark Fund - Balanced Portfolio

                                     -34-
<PAGE>

                     Benchmark Fund - Equity Index Portfolio

                     Benchmark Fund - Focused Growth Portfolio

                     Lastly, the Northern Trust Stock Fund (if applicable),
                     subject to the last paragraph of Section 6.4.

          A Participant's application for a loan shall be in such form (e.g.,
          by telephone, in writing) as the Committee shall determine.

                The note representing the loan (and other loans to the same
          Participant) shall be segregated in a separate fund held by the
          Trustee as a separate earmarked investment solely for the account of
          the Participant.  A Participant's payments to the Trust of principal
          and interest on a note held in such a segregated fund shall be
          invested, as soon as practicable, in such one or more of the
          Investment Funds in the same manner as deposits or contributions to
          each applicable Account are invested from time to time.

          (e) If the Participant fails to repay the loan according to its
          terms, or if the Participant ceases to participate in the Thrift Plan,
          the Committee may foreclose on the loan and, among other things, may
          distribute the loan to the Participant or his or her Beneficiary, to
          the extent permitted by law.  Such distributions shall be considered
          in determining the Vested Portion of a Participant's Bank Matching
          Contribution Account under Section 2.22.  A loan, as an asset of a
          Participant's Account, shall be valued at par and used first in
          distributing benefits to the Participant or his or her Beneficiary
          under Sections 9.5 and 12.5.

          (f) The Committee may delegate any or all of its powers and
          responsibilities under this Section 8.7 to one or more of its members
          or any other person.


  SECTION 9. DISTRIBUTION OF BENEFITS.
             ------------------------- 

      9.1 Termination of Service.  A benefit payable to a Participant upon
      termination of service shall be distributed in one lump sum, subject to
      Section 8.4.

                                     -35-
<PAGE>

      9.2 Death.  A benefit payable to a Beneficiary upon the death of a
      Participant shall be distributed in one lump sum.

      9.3 Time of Payment.  A lump sum payment shall be made as soon as
      reasonably practicable (and under ordinary circumstances in no more than
      45 days) after the Valuation Date as of which the benefit is determined.

      9.4 Deferral of Payment of Benefit.  If a Participant or his or her
      Beneficiary could receive a Bank contingent matching contribution for the
      calendar year in which the Participant terminates his or her participation
      in the Thrift Plan as provided in Section 5.1(b), then notwithstanding
      Section 9.3 the Participant or Beneficiary may elect to defer payment
      under that Section until the Bank makes such a contingent contribution, or
      if none, until the Bank announces that no such contribution will be made.
      In such case, the lump sum payment shall be made as soon as reasonably
      practicable (but in no event more than 45 days) after the Valuation Date
      immediately following that date.  Until such Valuation Date, the benefit
      of a Participant or Beneficiary shall be treated in all respects as are
      the Accounts of continuing Participants, except that (a) no additions to
      such accounts may be made, and (b) the Participant or Beneficiary may not
      exercise the rights granted under Sections 8.5 and 8.7 of this Thrift
      Plan.

      9.5 Distributions from  Northern Trust Stock Fund.  A benefit normally
      will be distributed in cash, although the Committee may make distribution
      partly or wholly in kind.  Notwithstanding the foregoing, upon the written
      request of a Participant or his or her Beneficiary, as the case may be,
      distribution of the Participant's interest in the Northern Trust Stock
      Fund shall be made in kind in full shares of common stock of Northern
      Trust Corporation, with any balance representing a fraction of a share
      being paid in cash.  Such distributions shall be made as soon as
      reasonably practicable after the Valuation Date as of which such benefit
      is determined, and all distributions with respect to any Valuation Date
      shall be made on the same date.  Common stock of Northern Trust
      Corporation and other property distributed in kind shall be valued at its
      fair market value on the Valuation Date as of which the benefit is
      determined.

                                     -36-

      SECTION 9.6    Direct Rollover of Eligible Rollover Distributions.
                     ---------------------------------------------------

           (a) This Section 9.6 applies to distributions made on or after
      January 1, 1993.  Notwithstanding any provision of the Thrift 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.

           (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 an employee or former
      employee.  In addition, the employee's or former employee's surviving
      spouse and the employee's or former employee'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.

                                     -37-
<PAGE>

           (4) Direct rollover:  A direct rollover is a payment by the Thrift
      Plan to the eligible retirement plan specified by the distributee.

  SECTION 10. THE COMMITTEE.
              --------------

      10.1 Powers.  The Committee shall have all powers necessary to discharge
      its duties in administering the Thrift Plan including, but not by way of
      limitation, the power to interpret or construe the Thrift Plan, to
      determine all questions of eligibility and the status and rights of
      Participants, Beneficiaries and other persons, and to discharge disputes
      arising under the Thrift Plan.  The Committee shall have discretionary
      authority to determine eligibility for benefits and to construe the terms
      of the Thrift Plan.  Notwithstanding the foregoing, no member of the
      Committee shall participate in any action on any matter involving solely
      his or her own rights or benefits as a Participant under the Thrift Plan,
      and any such matters shall be determined by the other members of the
      Committee.  Any action by the Committee shall be subject to appeal to the
      Employee Benefit Policy Committee of The Northern Trust Company.

      10.2 Directions to Trustee.  The Committee shall direct the Trustee
      concerning all payments which shall be made out of the Thrift Trust
      pursuant to the provisions of the Thrift Plan.  Any direction to the
      Trustee shall be in writing, signed by the Secretary of the Committee or
      any member thereof.

      10.3 Agents.  The Committee may retain counsel, employ agents and provide
      for such clerical, medical, accounting, auditing, and other services as it
      may require in carrying out the provisions of the Thrift Plan.

      10.4 Compensation.  Members of the Committee shall not receive
      compensation for their service in connection with the Thrift Plan, but the
      Bank shall reimburse them for any necessary expenses incurred in the
      discharge of their duties.

      10.5 Reports.  The Committee shall keep on file, in such form as it shall
      deem convenient and proper, all reports of the Thrift Trust received from
      the Trustee.  The Committee shall give to each Participant a written
      report of the amount of his or her Deposit Accounts and Bank Contribution
      Accounts at annual or more frequent intervals.  Additional reports may be
      given to a Participant by telephone.

                                     -38-

  SECTION 11. GENERAL PROVISIONS.
              -------------------

      11.1 Spendthrift.  The interests of Participants and Beneficiaries in the
      Thrift 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, except that the
      interests of a Participant may be subject to qualified domestic relations
      orders and loans from the Thrift Trust to the Participant.

      11.2 Facility of Payment.  If any benefit pursuant to the provisions of
      Section 8.1, 8.2 or 8.3 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 properly
      to manage his or her affairs, such benefit may 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
            Transfers or Gifts to Minors Act for the person; or

            (c) to the person's attorney-in-fact, spouse, adult child, or blood
            relative.

      Any benefit so paid shall be a complete discharge of the liabilities of
      the Thrift Plan therefor.

      11.3 Missing Person.  If within three years after any benefit becomes due
      under the Thrift Plan to a Participant or Beneficiary, the Committee is
      unable to make payment because the identity or whereabouts of such person
      cannot be ascertained notwithstanding the mailing of notice to any last
      known address or addresses, the Committee shall make payment of such
      benefit as provided in Section 8.2 as though the Participant had died
      three years after the date such benefit became due.  In the event payment
      cannot be made pursuant to the provisions of Section 8.2 at that time, the
      Participant's Deposit Accounts and Bank Contribution Accounts shall be
      closed out and disposed of in the same manner as forfeitures as provided
      in Section 5.4, but the amount thereof shall be a continuing liability of
      the Thrift Plan.  In the event it shall become possible to make payment of
      the liability at a later date, the amount of the liability, plus interest
      (compounded annually, at the rate of 120% of the Federal mid-term rate as
      in effect each January), shall be paid in accordance

                                     -39-
<PAGE>

      with the provisions of the Thrift Plan.  The Bank shall simultaneously
      reimburse the Thrift Plan for the amount of any such payments.

      11.4 Interests of Participants.  No Participant or Beneficiary or any
      other person shall have any interest in or right under the Thrift Plan or
      in any assets or earnings of the Thrift Trust except as and to the extent
      provided in the Thrift Plan.

      11.5 Source of Benefits.  The Thrift Trust shall be the sole source of all
      benefits provided for in the Thrift Plan, and under no circumstances shall
      the Bank be liable or responsible for the payment of any such benefits.

      11.6 No Discrimination.  Whenever in the administration of the Thrift 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 officers,
      shareholders or highly compensated employees.

      11.7 Exclusive Benefit of Participants.  Except as provided in Section
      5.4, no part of any deposit by a Participant or of any contribution by the
      Bank under the provisions of the Thrift Plan or of any part of the Thrift
      Trust (other than such part as is required to pay taxes and expenses of
      administration and investment) shall be used for, or diverted to, purposes
      other than for the exclusive benefit of the Participants or their
      Beneficiaries.


  SECTION 12. AMENDMENT AND TERMINATION.
              --------------------------

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

      12.2 Termination.  It is the intention of the Bank to continue the Thrift
      Plan and to make contributions thereto, but the Bank reserves the right to
      terminate the Thrift Plan in whole or in part as of any Valuation Date by
      action of the Board of Directors and for any reason

                                     -40-
<PAGE>

      satisfactory to the Board of Directors.  Upon partial or full termination,
      all affected Participants shall become fully vested, and upon permanent
      discontinuance of contributions by the Bank, all Participants shall become
      fully vested.

      12.3 Merger, Sale.  In the event of any merger or consolidation of the
      Thrift Plan with, or transfer in whole or in part of the assets and
      liabilities of the Thrift 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 Thrift Plan shall be so
      merged or consolidated, or the assets of the Thrift Trust applicable to
      such Participants shall be so transferred, only if:

          (a) Each Participant would (if either the Thrift 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 entitled to receive immediately
          before the merger, consolidation or transfer (if the Thrift Plan had
          then terminated);

          (b) Resolutions of the Board of Directors or of any new or successor
          employer of the affected Participants, shall authorize such transfer
          of assets; and, in the case of the new or successor employer of the
          affected Participants, its resolutions shall include an assumption of
          liabilities with respect to such Participants' 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 Internal Revenue Code.

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

      12.4 Termination of Participation by Adopting Corporation.  In the event a
      corporation which has adopted the Thrift Plan shall by action of its board
      of directors, elect to terminate its participation therein, the Committee
      shall cause a valuation of the Trust Fund to be made to ascertain the
      value of assets of each of the Investment Funds which are attributable to
      Participants who are Employees of the terminating corporation or their
      Beneficiaries in the case of deceased Participants.  The Committee shall
      direct the Trustee

                                     -41-
<PAGE>

      to segregate assets of each of the Investment Funds which are deemed to be
      so attributable, together with all loans to such Participants from the
      Thrift Trust, and to make distribution to the Participants or their
      Beneficiaries as provided in Section 12.5 as if the Thrift Plan had
      terminated with respect to the Participants or their Beneficiaries of the
      terminating corporation.

      12.5 Distribution Upon Termination.  In the event of the termination of
      the Thrift Plan, there shall be distributed to each Participant, or to his
      or her Beneficiary in the case of a deceased Participant, a benefit equal
      to the sum of the value of the Participant's After-Tax Deposit Account,
      Before-Tax Deposit Account, Rollover Deposit Account, ESOP Contribution
      Account, Bank Basic Contribution Account, and Bank Matching Contribution
      Account in each of the Investment Funds, adjusted as provided in Section
      7.2 as of the Valuation Date on which termination occurs.  If such
      benefits shall not exhaust the assets of the Thrift Trust, any remaining
      assets shall be allocated to the Bank Matching Contribution Accounts of
      the Participants as though they were additional Bank contributions, and in
      no event shall any such assets revert to the Bank.

  SECTION 13.  EFFECTIVE DATE.  The Thrift Plan as amended and restated herein
  is effective as of July 1, 1993, except as otherwise provided herein.  The
  Committee may issue in writing uniform and non-discriminatory rules to carry
  out this amendment to the Thrift Plan (e.g., rules on changing a Participant's
  investments from the old Funds A, B, C-M, C-I and D to the new Investment
  Funds now described in Section 6.1).

  SECTION 14.  CONSTRUCTION.  The Thrift Plan shall be construed and
  administered pursuant to the terms of ERISA and the Internal Revenue Code of
  1986 and the laws of the State of Illinois, provided that in the case of
  conflict the provisions of federal law shall control.  The headings in the
  Thrift Plan are for convenience only and shall not be considered in construing
  the Plan.

  4.2 The Trust Fund shall consist of loans to Participants and the following
six  Investment Funds:

      Short Term Fund: This Fund invests primarily in debt instruments with 
      short maturity dates (e.g., money market instruments). This Fund shall be 
      invested with the objective of minimizing fluctuations in the market
      value of  the Fund, while obtaining maximum income consistent with that
      objective.

      Benchmark Funds - Bond Portfolio: This Fund invests primarily in debt
      instruments with longer maturity dates (e.g. bonds). 

      Benchmark Funds - Balanced Portfolio: This Fund invests in stocks, bonds 
      and money market instruments. The mix of these investments is continually 
      monitored and adjusted.

      Benchmark Funds - Equity Index Portfolio: This Fund invests primarily in 
      common stocks. The Fund seeks to achieve investment performance results 
      paralleling the results of the Standard & Poors 500 Stock Index. The
      Fund's  investments are not actively managed.

      Benchmark Funds - Focused Growth Portfolio: This Fund invests primarily in
      stocks of companies with high growth potential.

      Northern Trust Stock Fund: This Fund shall be invested primarily in shares
      of common stock of Northern Trust Corporation.

The Benchmark Fund is a registered investment company. The Northern Trust 
Company is the investment adviser, transfer agent and custodian for each 
portfolio of the Fund, and it receives from each portfolio a fee for its 
services. 

  The Trustee shall allocate contributions, deposits and payments on Participant
loans among the Investment Funds in the proportions specified by the Committee.

                    FINANCIAL HARDSHIP ELIGIBILITY CHECKLIST



MEDICAL/DENTAL

On August 8, 1988, IRS regulations were issued placing severe restrictions on
Financial Hardship Withdrawal of 401(k) (Before-tax contributions) funds.  These
funds may only be accessed if it is shown all other assets and loans available
to an individual are first exhausted.  The following checklist will aid you in
determining whether or not you are eligible to apply for a Financial Hardship
Withdrawal.


INSTRUCTIONS:

Answer the following questions to determine if you may apply for a Financial
Hardship Withdrawal.

Yes  No
         1. Are you eligible for a loan or "regular" withdrawal through TIP
            that satisfies the Financial Hardship request?   Amount $__________.
               See page two of your most recent TIP statement.


         2. Will you receive any reimbursement or compensation from insurance?
            Amount $__________.  Note:  If payment is required to obtain
            medical treatment, you may also be able to receive a withdrawal.


         3. Can the Financial Hardship be satisfied by liquidating assets
            of you, and/or your spouse and children?   Amount $__________.


         4. Are you able to obtain a loan from commercial sources? Amount
            $__________.


         5. Can the Financial Hardship be satisfied by ceasing contributions
            to TIP?   Amount $___________.

If you answered "yes" to any of the questions, you are ineligible for a
Financial Hardship unless the full amount of the Financial Hardship cannot be
satisfied by exhausting the funds available through numbers 1-5 above.  If these
measures are pursued completely and the Financial Hardship is still not
satisfied, you will need to complete a TIP Financial Hardship Application and
Personal Financial Statement, in addition to supplying accompanying
documentation.  Questions may be directed to Denise Freedman, ext. 4416, or
Debra Rock, ext. 7613.

Under IRS Financial Hardship Withdrawal guidelines, it must be demonstrated that
a hardship situation cannot be satisfied through depletion of assets and other
sources, including borrowing from a commercial source.  In order to consider a
request for Financial Hardship, proof of a loan denial from a lending
institution must be provided.  Please check one of the boxes below


         I have enclosed a Statement of Credit Denial for $_____________
         from _________________________________.  (A bank, credit union, finance
         company, or other financial institution.)


         I have secured a loan of $______________ to partially meet this
         Financial Hardship but was unable to borrow the full amount.  (You must
         include a copy of the loan note.)


         I have not applied for a commercial loan.

         ______  1.  I will apply for a loan of $____________ with a commercial
                     lender other than The Northern Trust.

         ______  2.  I authorize the Benefits Division to forward my completed
                     Personal Financial Statement to the Employee Loan Division
                     of The Northern Trust and obtain any credit reports
                     necessary to determine if I am eligible to apply for a loan
                     of $_____________.  I realize I must complete additional
                     loan forms for a Northern loan to be initiated.  To
                     expedite this request, I authorize Employee Loans to
                     forward any Statement of Credit Denial Directly to the TIP
                     Administrator, M-8.


I understand that failure to provide a statement of Credit Denial will be reason
for denial of TIP Financial Hardship funds.

                               TAX CONSIDERATIONS


NAME: ________________________________  SOC. SEC. #: ___________________________


The taxable portion of your withdrawal is subject to an automatic 20% Federal
income tax withholding on any amount that is not directly rolled over to an IRA
or another Employer's Plan.  The non-taxable part of your withdrawal is not
subject to tax withholding and cannot be transferred to an IRA or Employer's
Plan.  If you do not make a tax election, the 20% withholding will automatically
apply.  Please see the (Special Tax Notice, In-Service Withdrawals) attached to 
this form for a more detailed explanation.

NOTE:  To qualify for a Swing Loan from Employee Banking, the distribution must
       be payable to you and tax withholding will apply.

          Distribute my entire taxable withdrawal amount in a check payable to
          me. I understand that 20% of the taxable portion of the distribution
          will be withheld in Federal taxes.

          Rollover 100% of my taxable distribution to the IRA account/Employer
          Plan below.  I will withdraw the fund from this account/plan to meet
          the financial hardship need indicated in this application.

          Rollover $____________ of my taxable distribution and make the balance
          payable to me.  I understand that I must withdraw the funds from the
          account/plan to meet the financial hardship need indicated in this
          application and that 20% of the taxable balance paid to me will be
          withheld in taxes.

Direct Rollover My Funds to:

Your check will be made payable to this IRA account/Employer Plan and mailed to
you for deposit.


                        STATEMENT OF TRUTH AND ACCURACY

I have made every attempt to provide complete and accurate information on this
application.  I understand that any intentional misrepresentation of facts or
circumstances relating to this Financial Hardship Withdrawal Application or the
intentional withholding of relevant information is a major violation of Bank
policy and will result in disciplinary action and could lead to termination of
employment.

                               SPECIAL TAX NOTICE
                        IN-SERVICE WITHDRAWALS FROM TIP


This notice contains important information you will need before you decide how
to receive your payment from the Thrift Incentive Plan. (TIP)

                                    SUMMARY

A payment from TIP that is eligible for "rollover" can be taken in two ways.
You can have all or any portion of your payment either
      1) PAID IN A "DIRECT ROLLOVER"
      2) PAID TO YOU

A rollover is a payment of your TIP benefits to your individual retirement
arrangement (IRA) or to another employer's plan.  This choice will affect the
tax you owe.

   If you choose a DIRECT ROLLOVER:

      Your payment will not be taxed in the current year and no income tax will
      be withheld.
      Your payment will be made directly to your IRA or other employer's plan.
      Your payment will be taxed later when you take it out of the IRA or other
      employer's plan.

   If you choose to have your TIP Benefits PAID TO YOU:

      You will receive only 80% of the payment, because The Northern Trust is
      required to withhold 20% of the payment and send it to the IRS as income
      tax withholding to be credited against your taxes.

      Your payment will be taxed in the current year unless you roll it over.
      You may be able to use special tax rules that could reduce the tax you
      owe. (see pg. 4)  However, if you receive the payment before age 59 1/2,
      you also may have to pay an additional 10% tax.

      You can roll over the payment to your IRA or another employer's plan
      within 60 days of receiving the   payment.  The amount rolled over will
      not be taxed until you take it out of the IRA or employer's plan.

      If you want to roll over 100% of the payment to an IRA or another
      employer's plan, you must find other money to replace the 20% that was
      withheld.  If you roll over only the 80% that you received, you will be
      taxed on the 20% that was withheld and that is not rolled over.

      NOTE:
      Although taxable funds that come out of TIP as an in-service withdrawal
      are eligible for rollover, the funds will not be accepted for rollover
      back into TIP.

</TABLE>

                  PAYMENTS THAT CAN AND CANNOT BE ROLLED OVER

Payments from TIP may be "eligible rollover distributions." This means that
they can be rolled over to an IRA or another employer's plan.  In general, any
payment from TIP (including an in-service withdrawal) is considered an eligible
rollover distribution, EXCEPT for the following types of payments which CANNOT
be rolled over:

NON-TAXABLE PAYMENTS
    In general, only the "taxable portion" of your payment is an eligible
    rollover distribution.  If you have made "after-tax" employee contributions
    to TIP, these contributions will be non-taxable when they are paid to you,
    and they cannot be rolled over.

                                       7
<PAGE>

REQUIRED MINIMUM PAYMENTS
    Beginning in the year you reach age 70 1/2, you are required to take an
    annual distribution from TIP.  These required minimum distributions cannot
    be rolled over.


                                DIRECT ROLLOVER

You can choose a direct rollover of all or any portion of your payment that is
an "eligible rollover distribution," as described above.  In a direct rollover,
the eligible rollover distribution is made payable directly from TIP to an IRA
or another employer's plan.  If you choose a direct rollover, you are not taxed
on a payment until you later take it out of the IRA or employer's plan.


DIRECT ROLLOVER TO AN IRA

   You can open an IRA to receive the direct rollover. (The term "IRA" as used
in this notice includes individual   retirement accounts and individual
retirement annuities.) If you choose to have your payment made directly   to an
IRA, contact an IRA sponsor (usually a financial institution) to obtain an
account number.  Supply the   name of the institution and the account number on
your withdrawal form.  The check will then be made   payable to the IRA and
sent to you for delivery to the IRA institution.

DIRECT ROLLOVER TO ANOTHER EMPLOYER'S PLAN

   If you are employed by a new employer that has a plan, and you want a direct
rollover to that plan, ask the   administrator of that plan whether it will
accept your rollover. If the plan will accept your rollover, supply   the name
of the plan and the company name on your distribution or withdrawal form.  An
employer plan is   not legally required to accept a rollover.  If your new
employer's plan does not accept a rollover, you can   choose a direct rollover
to an IRA.

   PLEASE NOTE:
      Although taxable funds that come out of TIP as an in-service withdrawal
      are eligible for rollover, the funds will not be accepted for rollover 
      back into TIP.


                          PAYMENT MADE PAYABLE TO YOU

If you have the payment made to you, it is subject to 20% income tax
withholding.  The payment is taxed in the year you receive it unless, within 60 
days, you roll it over to an IRA or another plan that accepts rollovers.  If
you do not roll it over, special tax rules may apply.

MANDATORY TAX WITHHOLDING
   If any portion of the payment to you is an eligible rollover distribution,
   TIP is required by law to withhold 20% of that amount.  This amount is sent 
   to the IRS as income tax withholding.  For example, if your eligible 
   rollover distribution is $10,000, only $8,000 will be paid to you because
   TIP must withhold $2,000 as income tax.  However, when you prepare your 
   income tax return for the year, you will report the full $10,000 as a payment
   from TIP.  You will report the $2,000 as tax withheld, and it will be 
   credited against any income tax you owe for the year.

SIXTY-DAY ROLLOVER OPTION
   If you have an eligible rollover distribution paid to you, you can still
   decide to roll over all or part of it to an IRA or another employer's plan. 
   If you decide to roll over, you must make the rollover within 60 days 
   after you receive the payment.  The portion of your payment that is rolled 
   over will not be taxed until you take it out of the IRA or employer's plan.
 
   You can roll over up to 100% of the eligible rollover distribution, including
   an amount equal to the 20% that  was withheld.  If you choose to roll over  
   100%, you must find other money within the 60-day period to contribute to 
   the IRA or employer's plan to replace the 20% that was withheld.  On the    
   other hand, if you roll over only the 80% that you received, you will be 
   taxed on the 20% that was withheld.

                                       8
<PAGE>

    EXAMPLE:

      Your eligible rollover distribution is $ 10,000, and you choose to have it
paid to you.  You will receive $8,000, and $2,000 will be sent to the IRS as
income tax withholding.  Within 60 days after receiving the $8,000, you may roll
over the entire $10,000 to an IRA or employer's plan.  To do this, you roll over
the $8,000 you received from TIP, and you will have to find $2,000 from other
sources (your savings, a loan, etc.). In this case, the entire $10,000 is not
taxed until you take it out of the IRA or employer's plan.  If you roll over the
entire $10,000, when you file your income tax return, you may get a refund of
the $2,000 withheld.

If, on the other hand, you roll over only $8,000, the $2,000 you did not roll
over is taxed in the year it was withheld.  When you file your income tax return
you may get a refund of part of the $2,000 withheld.  (However, any refund is
likely to be larger if you roll over the entire $10,000.)

ADDITIONAL 10% TAX IF YOU ARE UNDER AGE 59 1/2
If you receive a payment before you reach age 59 1/2 and you do not roll it
over, then, in addition to the regular income tax, you may have to pay an extra
tax equal to 10% of the taxable portion of the payment.  The additional 10% tax
does not apply to your in-service withdrawal if it is (see IRS Form 5329 for
more information on the additional 10%):

       Used to pay certain medical expenses
       Paid to you under a Qualified Domestic Relations Order

SPECIAL TAX TREATMENT
If your eligible rollover distribution is not rolled over, it will be taxed in
the year you receive it.  However, if it qualifies as a "lump sum
distribution", it may be eligible for special tax treatment.  A lump sum
distribution is a payment, within one year, of your entire balance under TIP,
ESOP and the Pension Plan that is payable to you because you have reached age
59 1/2 or separated from service with your employer.  For a payment to qualify
as a lump sum distribution, you must have been a participant in the plan for at
least 5 years.  The special tax treatment for lump sum distributions is
described below.

FIVE-YEAR AVERAGING
If you receive a lump sum distribution after you are age 59 1/2, you may be
able to make a one-time election to figure the tax on the payment by using "5-
year averaging." Five-year averaging often reduces the tax you owe because it
treats the payment as if it were paid over 5 years.

TEN-YEAR AVERAGING IF YOU WERE BORN BEFORE JANUARY 1, 1936
If you receive a lump sum distribution and you were born before January 1,
1936, you can make a one-time election to figure the tax on the payment by
using "10-year averaging" (using 1986 tax rates).  Like the 5-year averaging
rules, 10-year averaging often reduces the tax you owe.

CAPITAL GAINS TREATMENT IF YOU WERE BORN BEFORE JANUARY 1, 1936
In addition, if you receive a lump sum distribution and you were born before
January 1, 1936, you may elect to have the part of your payment that is
attributable to your pre-1974 participation in the retirement plans (if any)
taxed as long-term capital gain at a rate of 20%.

There are other limits on the special tax treatment for lump sum distributions.
For example, you can generally elect this special tax treatment only once in
your lifetime, and the election applies to all lump sum distributions you
receive in that same year.  If you have previously rolled over a payment from
the Plan, you cannot use this special tax treatment for later payments from
TIP.  If you roll over your payment to an IRA. you will not be able to use this
special tax treatment for later payments from the IRA.  Also, if you roll over
only a portion of your payment to an IRA, this special tax treatment is not
available for the rest of the payment.  Additional restrictions are described
in IRS Form 4972, which has more information on lump sum distributions and how
you elect the special tax treatment.

             PAYMENTS UNDER A "QUALIFIED DOMESTIC RELATIONS ORDER"

 In general the rules summarized above that apply to payments to employees also
 apply to payments to alternate payees under a "Qualified Domestic Relations
 Order" (QDOR) in connections with a divorce or legal separation.

 If you are an alternate payee, you may choose to have an eligible rollover
 distribution paid in a direct rollover to an IRA or paid to you.  Your payment
 is not subject to the additional 10% tax described above, even if you are
 younger than age 59 1/2 and you may be able to use the special tax treatment
 for lump sum distributions and distributions in employer stock also described
 above.

                      HOW TO OBTAIN ADDITIONAL INFORMATION

 This notice summarizes only the federal (not state or local) tax rules that
 might apply to your payment.  The rules described above are complex and contain
 many conditions and exceptions that are not included in this notice.
 Therefore, you may want to consult with a professional tax advisor before you
 take payment of your benefits from TIP.  Also, you can find more specific
 information on the tax treatment of payments from qualified retirement plans in
 IRS Publication 575, PENSION AND ANNUITY INCOME, and IRS Publication 590,
 INDIVIDUAL RETIREMENT ARRANGEMENTS.  These publications are available from your
 local IRS office or by calling 1-800-TAX-FORMS.

                    FINANCIAL HARDSHIP ELIGIBILITY CHECKLIST



EVICTION/FORECLOSURE

On August 8, 1988, IRS regulations were issued placing severe restrictions on
Financial Hardship Withdrawal of 401(k) (Before-tax contributions) funds.  These
funds may only be accessed if it is shown all other assets and loans available
to an individual are first exhausted.  The following checklist will aid you in
determining whether or not you are eligible to apply for a Financial Hardship
Withdrawal.


INSTRUCTIONS:

Answer the following questions to determine if you may apply for a Financial
Hardship Withdrawal.

Yes  No
         1. Are you eligible for a loan or "regular" withdrawal through TIP
            that satisfies the Financial Hardship request?   Amount $__________.
               See page two of your most recent TIP statement.


         2. Will you receive any reimbursement or compensation from insurance?
            Amount $__________.  Note:  If payment is required to obtain
            medical treatment, you may also be able to receive a withdrawal.


         3. Can the Financial Hardship be satisfied by liquidating assets
            of you, and/or your spouse and children?   Amount $__________.


         4. Are you able to obtain a loan from commercial sources? Amount
            $__________.


         5. Can the Financial Hardship be satisfied by ceasing contributions
            to TIP?   Amount $___________.

If you answered "yes" to any of the questions, you are ineligible for a
Financial Hardship unless the full amount of the Financial Hardship cannot be
satisfied by exhausting the funds available through numbers 1-5 above.  If these
measures are pursued completely and the Financial Hardship is still not
satisfied, you will need to complete a TIP Financial Hardship Application and
Personal Financial Statement, in addition to supplying accompanying
documentation.  Questions may be directed to Denise Freedman, ext. 4416, or
Debra Rock, ext. 7613.

Under IRS Financial Hardship Withdrawal guidelines, it must be demonstrated that
a hardship situation cannot be satisfied through depletion of assets and other
sources, including borrowing from a commercial source.  In order to consider a
request for Financial Hardship, proof of a loan denial from a lending
institution must be provided.  Please check one of the boxes below


         I have enclosed a Statement of Credit Denial for $_____________
         from _________________________________.  (A bank, credit union, finance
         company, or other financial institution.)


         I have secured a loan of $______________ to partially meet this
         Financial Hardship but was unable to borrow the full amount.  (You must
         include a copy of the loan note.)


         I have not applied for a commercial loan.

         ______  1.  I will apply for a loan of $____________ with a commercial
                     lender other than The Northern Trust.

         ______  2.  I authorize the Benefits Division to forward my completed
                     Personal Financial Statement to the Employee Loan Division
                     of The Northern Trust and obtain any credit reports
                     necessary to determine if I am eligible to apply for a loan
                     of $_____________.  I realize I must complete additional
                     loan forms for a Northern loan to be initiated.  To
                     expedite this request, I authorize Employee Loans to
                     forward any Statement of Credit Denial Directly to the TIP
                     Administrator, M-8.


I understand that failure to provide a statement of Credit Denial will be reason
for denial of TIP Financial Hardship funds.

                               TAX CONSIDERATIONS


NAME: __________________________________  SOC. SEC. #: _________________________


The taxable portion of your withdrawal is subject to an automatic 20% Federal
income tax withholding on any amount that is not directly rolled over to an IRA
or another Employer's Plan.  The non-taxable part of your withdrawal is not
subject to tax withholding and cannot be transferred to an IRA or Employer's
Plan.  If you do not make a tax election, the 20% withholding will automatically
apply.  Please see the (Special Tax Notice, In-Service Withdrawals) attached 
to this form for a more detailed explanation.

NOTE:  To qualify for a Swing Loan from Employee Banking, the distribution must
       be payable to you and tax withholding will apply.

          Distribute my entire taxable withdrawal amount in a check payable to

                               SPECIAL TAX NOTICE
                        IN-SERVICE WITHDRAWALS FROM TIP


This notice contains important information you will need before you decide how
to receive your payment from the Thrift Incentive Plan. (TIP)

                                    SUMMARY

A payment from TIP that is eligible for "rollover" can be taken in two ways.
You can have all or any portion of your payment either
     1) PAID IN A "DIRECT ROLLOVER"
     2) PAID TO YOU

A rollover is a payment of your TIP benefits to your individual retirement
arrangement (IRA) or to another employer's plan.  This choice will affect the
tax you owe.

  If you choose a DIRECT ROLLOVER:

     Your payment will not be taxed in the current year and no income tax will
     be withheld.
     Your payment will be made directly to your IRA or other employer's plan.
     Your payment will be taxed later when you take it out of the IRA or other
     employer's plan.

  If you choose to have your TIP Benefits PAID TO YOU:

     You will receive only 80% of the payment, because The Northern Trust is
     required to withhold 20% of the payment and send it to the IRS as income
     tax withholding to be credited against your taxes.

     Your payment will be taxed in the current year unless you roll it over. You
     may be able to use special tax rules that could reduce the tax you owe.
     (see pg. 4)  However, if you receive the payment before age 59 1/2, you
     also may have to pay an additional 10% tax.

     You can roll over the payment to your IRA or another employer's plan within
     60 days of receiving the payment.  The amount rolled over will not be
     taxed until you take it out of the IRA or employer's plan.

     If you want to roll over 100% of the payment to an IRA or another
     employer's plan, you must find other money to replace the 20% that was
     withheld.  If you roll over only the 80% that you received, you will be
     taxed on the 20% that was withheld and that is not rolled over.

     NOTE:
     Although taxable funds that come out of TIP as an in-service withdrawal-are
     eligible for rollover, the funds will not be accepted for rollover back
     into TIP.

</TABLE>

                  PAYMENTS THAT CAN AND CANNOT BE ROLLED OVER

Payments from TIP may be "eligible rollover distributions." This means that they
can be rolled over to an IRA or another employer's plan.  In general, any
payment from TIP (including an in-service withdrawal) is considered an eligible
rollover distribution, EXCEPT for the following types of payments which CANNOT
be rolled over:

NON-TAXABLE PAYMENTS
   In general, only the "taxable portion" of your payment is an eligible
   rollover distribution.  If you have made "after-tax" employee contributions
   to TIP, these contributions will be non-taxable when they are paid to you,
   and they cannot be rolled over.

                                       7
      
<PAGE>

REQUIRED MINIMUM PAYMENTS
   Beginning in the year you reach age 70 1/2, you are required to take an
   annual distribution from TIP.  These required minimum distributions cannot be
   rolled over.


                                DIRECT ROLLOVER

You can choose a direct rollover of all or any portion of your payment that is
an "eligible rollover distribution," as described above.  In a direct rollover,
the eligible rollover distribution is made payable directly from TIP to an IRA
or another employer's plan.  If you choose a direct rollover, you are not taxed
on a payment until you later take it out of the IRA or employer's plan.


DIRECT ROLLOVER TO AN IRA
   You can open an IRA to receive the direct rollover. (The term "IRA" as used
   in this notice includes individual retirement accounts and individual
   retirement annuities.) If you choose to have your payment made directly to an
   IRA, contact an IRA sponsor (usually a financial institution) to obtain an
   account number.  Supply the name of the institution and the account number on
   your withdrawal form.  The check will then be made payable to the IRA and
   sent to you for delivery to the IRA institution.

DIRECT ROLLOVER TO ANOTHER EMPLOYER'S PLAN
   If you are employed by a new employer that has a plan, and you want a direct
   rollover to that plan, ask the administrator of that plan whether it will
   accept your rollover. If the plan will accept your rollover, supply the name
   of the plan and the company name on your distribution or withdrawal form.  An
   employer plan is not legally required to accept a rollover.  If your new
   employer's plan does not accept a rollover, you can choose a direct rollover
   to an IRA.

   PLEASE NOTE:
      Although taxable funds that come out of TIP as an in-service withdrawal
      are eligible for rollover, the funds will not be accepted for rollover
      back into TIP.


                          PAYMENT MADE PAYABLE TO YOU

If you have the payment made to you, it is subject to 20% income tax
withholding.  The payment is taxed in the year you receive it unless, within 60
days, you roll it over to an IRA or another plan that accepts rollovers.  If you
do not roll it over, special tax rules may apply.

MANDATORY TAX WITHHOLDING
   If any portion of the payment to you is an eligible rollover distribution, 
   TIP is required by law to withhold 20% of that amount.  This amount is sent 
   to the IRS as income tax withholding.  For example, if your eligible 
   rollover distribution is $10,000, only $8,000 will be paid to you because 
   TIP must withhold $2,000 as income tax. However, when you prepare  your
   income tax return for the year, you will report the full $10,000 as a 
   payment from TIP. You will report the $2,000 as tax withheld, and it will be
   credited against any income tax you owe for the year.
   
SIXTY-DAY ROLLOVER OPTION
   If you have an eligible rollover distribution paid to you, you can still
   decide to roll over all or part of it to an IRA or another employer's plan.  
   If you decide to roll over, you must make the rollover within 60 days after 
   you receive the payment.  The portion of your payment that is rolled over 
   will not be taxed until you take it out of the IRA or employer's plan. 
 
   You can roll over up to 100% of the eligible rollover distribution, 
   including an amount equal to the 20% that was withheld.  If you choose to 
   roll over 100%, you must find other money within the 60-day period to 
   contribute to the IRA or employer's plan to replace the 20% that was        
   withheld.  On the other hand, if you roll over only the 80% that you 
   received, you will be taxed on the 20% that was withheld.

                                       8

   EXAMPLE:

      Your eligible rollover distribution is $10,000, and you choose to have it
      paid to you.  You will receive $8,000, and $2,000 will be sent to the IRS
      as income tax withholding.  Within 60 days after receiving the $8,000, you
      may roll over the entire $10,000 to an IRA or employer's plan.  To do
      this, you roll over the $8,000 you received from TIP, and you will have to
      find $2,000 from other sources (your savings, a loan, etc.). In this case,
      the entire $10,000 is not taxed until you take it out of the IRA or
      employer's plan. If you roll over the entire $10,000, when you file your
      income tax return, you may get a refund of the $2,000 withheld.

If, on the other hand, you roll over only $8,000, the $2,000 you did not roll
over is taxed in the year it was withheld.  When you file your income tax return
you may get a refund of part of the $2,000 withheld. (However, any refund is
likely to be larger if you roll over the entire $10,000.)

ADDITIONAL 10% TAX IF YOU ARE UNDER AGE 59 1/2
If you receive a payment before you reach age 59 1/2 and you do not roll it
over, then, in addition to the regular income tax, you may have to pay an extra
tax equal to 10% of the taxable portion of the payment.  The additional 10% tax
does not apply to your in-service withdrawal if it is (see IRS Form 5329 for
more information on the additional 10%):

      Used to pay certain medical expenses
      Paid to you under a Qualified Domestic Relations Order

SPECIAL TAX TREATMENT
If your eligible rollover distribution is not rolled over, it will be taxed in
the year you receive it.  However, if it qualifies as a "lump sum distribution",
it may be eligible for special tax treatment.  A lump sum distribution is a
payment, within one year, of your entire balance under TIP, ESOP and the Pension
Plan that is payable to you because you have reached age 59 1/2 or separated
from service with your employer.  For a payment to qualify as a lump sum
distribution, you must have been a participant in the plan for at least 5 years.
The special tax treatment for lump sum distributions is described below.

FIVE-YEAR AVERAGING
If you receive a lump sum distribution after you are age 59 1/2, you may be able
to make a one-time election to figure the tax on the payment by using "5-year
averaging." Five-year averaging often reduces the tax you owe because it treats
the payment as if it were paid over 5 years.

TEN-YEAR AVERAGING IF YOU WERE BORN BEFORE JANUARY 1, 1936
If you receive a lump sum distribution and you were born before January 1, 1936,
you can make a one-time election to figure the tax on the payment by using "10-
year averaging" (using 1986 tax rates).  Like the 5-year averaging rules, 10-
year averaging often reduces the tax you owe.

CAPITAL GAINS TREATMENT IF YOU WERE BORN BEFORE JANUARY 1, 1936
In addition, if you receive a lump sum distribution and you were born before
January 1, 1936, you may elect to have the part of your payment that is
attributable to your pre-1974 participation in the retirement plans (if any)
taxed as long-term capital gain at a rate of 20%.

There are other limits on the special tax treatment for lump sum distributions.
For example, you can generally elect this special tax treatment only once in
your lifetime, and the election applies to all lump sum distributions you
receive in that same year.  If you have previously rolled over a payment from
the Plan, you cannot use this special tax treatment for later payments from TIP.
If you roll over your payment to an IRA, you will not be able to use this
special tax treatment for later payments from the IRA.  Also, if you roll over
only a portion of your payment to an IRA, this special tax treatment is not
available for the rest of the payment.  Additional restrictions are described in
IRS Form 4972, which has more information on lump sum distributions and how you
elect the special tax treatment.

<PAGE>

             PAYMENTS UNDER A "QUALIFIED DOMESTIC RELATIONS ORDER"

In general the rules summarized above that apply to payments to employees also
apply to payments to alternate payees under a "Qualified Domestic Relations
Order" (QDOR) in connections with a divorce or legal separation.

If you are an alternate payee, you may choose to have an eligible rollover
distribution paid in a direct rollover to an IRA or paid to you.  Your payment
is not subject to the additional 10% tax described above, even if you are
younger than age 59 1/2 and you may be able to use the special tax treatment for
lump sum distributions and distributions in employer stock also described above.

                      HOW TO OBTAIN ADDITIONAL INFORMATION

This notice summarizes only the federal (not state or local) tax rules that
might apply to your payment.  The rules described above are complex and contain
many conditions and exceptions that are not included in this notice.  Therefore,
you may want to consult with a professional tax advisor before you take payment
of your benefits from TIP.  Also, you can find more specific information on the
tax treatment of payments from qualified retirement plans in IRS Publication
575, PENSION AND ANNUITY INCOME, and IRS Publication 590, INDIVIDUAL RETIREMENT
ARRANGEMENTS.  These publications are available from your local IRS office or by
calling 1-800-TAX-FORMS.

                    FINANCIAL HARDSHIP ELIGIBILITY CHECKLIST



PRIMARY RESIDENCE

On August 8, 1988, IRS regulations were issued placing severe restrictions on
Financial Hardship Withdrawal of 401(k) (Before-tax contributions) funds.  These
funds may only be accessed if it is shown all other assets and loans available
to an individual are first exhausted.  The following checklist will aid you in
determining whether or not you are eligible to apply for a Financial Hardship
Withdrawal.


INSTRUCTIONS:

Answer the following questions to determine if you may apply for a Financial
Hardship Withdrawal.

Yes  No
         1. Are you eligible for a loan or "regular" withdrawal through TIP
            that satisfies the Financial Hardship request?   Amount $__________.
               See page two of your most recent TIP statement.


         2. Will you receive any reimbursement or compensation from insurance?
            Amount $__________.  Note:  If payment is required to obtain
            medical treatment, you may also be able to receive a withdrawal.


         3. Can the Financial Hardship be satisfied by liquidating assets
            of you, and/or your spouse and children?   Amount $__________.


         4. Are you able to obtain a loan from commercial sources? Amount
            $__________.


         5. Can the Financial Hardship be satisfied by ceasing contributions
            to TIP?   Amount $___________.

If you answered "yes" to any of the questions, you are ineligible for a
Financial Hardship unless the full amount of the Financial Hardship cannot be
satisfied by exhausting the funds available through numbers 1-5 above.  If these
measures are pursued completely and the Financial Hardship is still not
satisfied, you will need to complete a TIP Financial Hardship Application and
Personal Financial Statement, in addition to supplying accompanying
documentation.  Questions may be directed to Denise Freedman, ext. 4416, or
Debra Rock, ext. 7613.

Under IRS Financial Hardship Withdrawal guidelines, it must be demonstrated that
a hardship situation cannot be satisfied through depletion of assets and other
sources, including borrowing from a commercial source.  In order to consider a
request for Financial Hardship, proof of a loan denial from a lending
institution must be provided.  Please check one of the boxes below


         I have enclosed a Statement of Credit Denial for $_____________
         from _________________________________.  (A bank, credit union, finance
         company, or other financial institution.)


         I have secured a loan of $______________ to partially meet this
         Financial Hardship but was unable to borrow the full amount.  (You must
         include a copy of the loan note.)


         I have not applied for a commercial loan.

         ______  1.  I will apply for a loan of $____________ with a commercial
                 lender other than The Northern Trust.

         ______  2.  I authorize the Benefits Division to forward my completed
                 Personal Financial Statement to the Employee Loan Division
                 of The Northern Trust and obtain any credit reports
                 necessary to determine if I am eligible to apply for a loan
                 of $_____________.  I realize I must complete additional loan
                 forms for a Northern loan to be initiated.  To expedite this
                 request, I authorize Employee Loans to forward any Statement
                 of Credit Denial Directly to the TIP Administrator, M-8.


I understand that failure to provide a statement of Credit Denial will be reason
for denial of TIP Financial Hardship funds.

The taxable portion of your withdrawal is subject to an automatic 20% Federal
income tax withholding on any amount that is not directly rolled over to an IRA
or another Employer's Plan.  The non-taxable part of your withdrawal is not
subject to tax withholding and cannot be transferred to an IRA or Employer's
Plan.  If you do not make a tax election, the 20% withholding will automatically
apply.  Please see the (Special Tax Notice, In-Service Withdrawals) attached 
to this form for a more detailed explanation.

NOTE:  To qualify for a Swing Loan from Employee Banking, the distribution must
       be payable to you and tax withholding will apply.

          Distribute my entire taxable withdrawal amount in a check payable to
          me. I understand that 20% of the taxable portion of the distribution
          will be withheld in Federal taxes.

          Rollover 100% of my taxable distribution to the IRA account/Employer
          Plan below.  I will withdraw the fund from this account/plan to meet
          the financial hardship need indicated in this application.

          Rollover $____________ of my taxable distribution and make the balance
          payable to me.  I understand that I must withdraw the funds from the
          account/plan to meet the financial hardship need indicated in this
          application and that 20% of the taxable balance paid to me will be

                               SPECIAL TAX NOTICE
                        IN-SERVICE WITHDRAWALS FROM TIP


This notice contains important information you will need before you decide how
to receive your payment from the Thrift Incentive Plan. (TIP)

                                    SUMMARY

A payment from TIP that is eligible for "rollover" can be taken in two ways.
You can have all or any portion of your payment either
     1) PAID IN A "DIRECT ROLLOVER"
     2) PAID TO YOU

A rollover is a payment of your TIP benefits to your individual retirement
arrangement (IRA) or to another employer's plan.  This choice will affect the
tax you owe.

  If you choose a DIRECT ROLLOVER:

     Your payment will not be taxed in the current year and no income tax will
     be withheld.
     Your payment will be made directly to your IRA or other employer's plan.
     Your payment will be taxed later when you take it out of the IRA or other
     employer's plan.

  If you choose to have your TIP Benefits PAID TO YOU:

     You will receive only 80% of the payment, because The Northern Trust is
     required to withhold 20% of the payment and send it to the IRS as income
     tax withholding to be credited against your taxes.

     Your payment will be taxed in the current year unless you roll it over. You
     may be able to use special tax rules that could reduce the tax you owe.
     (see pg. 4)  However, if you receive the payment before age 59 1/2, you
     also may have to pay an additional 10% tax.

     You can roll over the payment to your IRA or another employer's plan within
     60 days of receiving the payment.  The amount rolled over will not be
     taxed until you take it out of the IRA or employer's plan.

     If you want to roll over 100% of the payment to an IRA or another
     employer's plan, you must find other money to replace the 20% that was
     withheld.  If you roll over only the 80% that you received, you will be
     taxed on the 20% that was withheld and that is not rolled over.

     NOTE:
     Although taxable funds that come out of TIP as an in-service withdrawal are
     eligible for rollover, the funds will not be accepted for rollover back 
     into TIP.

</TABLE>

                  PAYMENTS THAT CAN AND CANNOT BE ROLLED OVER

Payments from TIP may be "eligible rollover distributions." This means that they
can be rolled over to an IRA or another employer's plan.  In general, any
payment from TIP (including an in-service withdrawal) is considered an eligible
rollover distribution, EXCEPT for the following types of payments which CANNOT
be rolled over:

NON-TAXABLE PAYMENTS
   In general, only the "taxable portion" of your payment is an eligible
   rollover distribution.  If you have made "after-tax" employee contributions
   to TIP, these contributions will be non-taxable when they are paid to you,
   and they cannot be rolled over.

                                       7
<PAGE>

REQUIRED MINIMUM PAYMENTS
   Beginning in the year you reach age 70 1/2, you are required to take an
   annual distribution from TIP.  These required minimum distributions cannot be
   rolled over.


                                DIRECT ROLLOVER

You can choose a direct rollover of all or any portion of your payment that is
an "eligible rollover distribution," as described above.  In a direct rollover,
the eligible rollover distribution is made payable directly from TIP to an IRA
or another employer's plan.  If you choose a direct rollover, you are not taxed
on a payment until you later take it out of the IRA or employer's plan.


DIRECT ROLLOVER TO AN IRA
   You can open an IRA to receive the direct rollover. (The term "IRA" as used
   in this notice includes individual retirement accounts and individual
   retirement annuities.) If you choose to have your payment made directly to an
   IRA, contact an IRA sponsor (usually a financial institution) to obtain an
   account number.  Supply the name of the institution and the account number on
   your withdrawal form.  The check will then be made payable to the IRA and
   sent to you for delivery to the IRA institution.

DIRECT ROLLOVER TO ANOTHER EMPLOYER'S PLAN
   If you are employed by a new employer that has a plan, and you want a direct
   rollover to that plan, ask the administrator of that plan whether it will
   accept your rollover. If the plan will accept your rollover, supply the name
   of the plan and the company name on your distribution or withdrawal form.  An
   employer plan is not legally required to accept a rollover.  If your new
   employer's plan does not accept a rollover, you can choose a direct rollover
   to an IRA.

   PLEASE NOTE:
      Although taxable funds that come out of TIP as an in-service withdrawal
      are eligible for rollover, the funds will not be accepted for rollover
      back into TIP.


                          PAYMENT MADE PAYABLE TO YOU

If you have the payment made to you, it is subject to 20% income tax
withholding.  The payment is taxed in the year you receive it unless, within 60
days, you roll it over to an IRA or another plan that accepts rollovers.  If you
do not roll it over, special tax rules may apply.

MANDATORY TAX WITHHOLDING
   If any portion of the payment to you is an eligible rollover distribution, 
   TIP is required by law to withhold 20% of that amount.  This amount is sent 
   to the IRS as income tax withholding.  For example, if your eligible 
   rollover distribution is $10,000, only $8,000 will be paid to you because 
   TIP must withhold $2,000 as income tax. However, when you prepare  your
   income tax return for the year, you will report the full $10,000 as a 
   payment from TIP. You will report the $2,000 as tax withheld, and it will be
   credited against any income tax you owe for the year.
   
SIXTY-DAY ROLLOVER OPTION
   If you have an eligible rollover distribution paid to you, you can still
   decide to roll over all or part of it to an IRA or another employer's plan.  
   If you decide to roll over, you must make the rollover within 60 days after 
   you receive the payment.  The portion of your payment that is rolled over 
   will not be taxed until you take it out of the IRA or employer's plan. 
 
   You can roll over up to 100% of the eligible rollover distribution, 
   including an amount equal to the 20% that was withheld.  If you choose to 
   roll over 100%, you must find other money within the 60-day period to 
   contribute to the IRA or employer's plan to replace the 20% that was        
   withheld.  On the other hand, if you roll over only the 80% that you 
   received, you will be taxed on the 20% that was withheld.

   EXAMPLE:

      Your eligible rollover distribution is $10,000, and you choose to have it
paid to you.  You will receive $8,000, and $2,000 will be sent to the IRS as
income tax withholding.  Within 60 days after receiving the $8,000, you may roll
over the entire $10,000 to an IRA or employer's plan.  To do this, you roll over
the $8,000 you received from TIP, and you will have to find $2,000 from other
sources (your savings, a loan, etc.). In this case, the entire $10,000 is not
taxed until you take it out of the IRA or employer's plan. If you roll over the
entire $10,000, when you file your income tax return, you may get a refund of
the $2,000 withheld.

If, on the other hand, you roll over only $8,000, the $2,000 you did not roll
over is taxed in the year it was withheld.  When you file your income tax return
you may get a refund of part of the $2,000 withheld. (However, any refund is
likely to be larger if you roll over the entire $10,000.)

ADDITIONAL 10% TAX IF YOU ARE UNDER AGE 59 1/2
If you receive a payment before you reach age 59 1/2 and you do not roll it
over, then, in addition to the regular income tax, you may have to pay an extra
tax equal to 10% of the taxable portion of the payment.  The additional 10% tax
does not apply to your in-service withdrawal if it is (see IRS Form 5329 for
more information on the additional 10%):

      Used to pay certain medical expenses
      Paid to you under a Qualified Domestic Relations Order

SPECIAL TAX TREATMENT
If your eligible rollover distribution is not rolled over, it will be taxed in
the year you receive it.  However, if it qualifies as a "lump sum distribution",
it may be eligible for special tax treatment.  A lump sum distribution is a
payment, within one year, of your entire balance under TIP, ESOP and the Pension
Plan that is payable to you because you have reached age 59 1/2 or separated
from service with your employer.  For a payment to qualify as a lump sum
distribution, you must have been a participant in the plan for at least 5 years.
The special tax treatment for lump sum distributions is described below.

FIVE-YEAR AVERAGING
If you receive a lump sum distribution after you are age 59 1/2, you may be able
to make a one-time election to figure the tax on the payment by using "5-year
averaging." Five-year averaging often reduces the tax you owe because it treats
the payment as if it were paid over 5 years.

TEN-YEAR AVERAGING IF YOU WERE BORN BEFORE JANUARY 1, 1936
If you receive a lump sum distribution and you were born before January 1, 1936,
you can make a one-time election to figure the tax on the payment by using "10-
year averaging" (using 1986 tax rates).  Like the 5-year averaging rules, 10-
year averaging often reduces the tax you owe.

CAPITAL GAINS TREATMENT IF YOU WERE BORN BEFORE JANUARY 1, 1936
In addition, if you receive a lump sum distribution and you were born before
January 1, 1936, you may elect to have the part of your payment that is
attributable to your pre-1974 participation in the retirement plans (if any)
taxed as long-term capital gain at a rate of 20%.

There are other limits on the special tax treatment for lump sum distributions.
For example, you can generally elect this special tax treatment only once in
your lifetime, and the election applies to all lump sum distributions you
receive in that same year.  If you have previously rolled over a payment from
the Plan, you cannot use this special tax treatment for later payments from TIP.
If you roll over your payment to an IRA, you will not be able to use this
special tax treatment for later payments from the IRA.  Also, if you roll over
only a portion of your payment to an IRA, this special tax treatment is not
available for the rest of the payment.  Additional restrictions are described in
IRS Form 4972, which has more information on lump sum distributions and how you
elect the special tax treatment.

             PAYMENTS UNDER A "QUALIFIED DOMESTIC RELATIONS ORDER"

In general the rules summarized above that apply to payments to employees also
apply to payments to alternate payees under a "Qualified Domestic Relations
Order" (QDOR) in connections with a divorce or legal separation.

If you are an alternate payee, you may choose to have an eligible rollover
distribution paid in a direct rollover to an IRA or paid to you.  Your payment
is not subject to the additional 10% tax described above, even if you are
younger than age 59 1/2 and you may be able to use the special tax treatment for
lump sum distributions and distributions in employer stock also described above.

                      HOW TO OBTAIN ADDITIONAL INFORMATION

This notice summarizes only the federal (not state or local) tax rules that
might apply to your payment.  The rules described above are complex and contain
many conditions and exceptions that are not included in this notice.  Therefore,
you may want to consult with a professional tax advisor before you take payment
of your benefits from TIP.  Also, you can find more specific information on the
tax treatment of payments from qualified retirement plans in IRS Publication
575, PENSION AND ANNUITY INCOME, and IRS Publication 590, INDIVIDUAL RETIREMENT
ARRANGEMENTS.  These publications are available from your local IRS office or by
calling 1-800-TAX-FORMS.

                    FINANCIAL HARDSHIP ELIGIBILITY CHECKLIST



TUITION

On August 8, 1988, IRS regulations were issued placing severe restrictions on
Financial Hardship Withdrawal of 401(k) (Before-tax contributions) funds.  These
funds may only be accessed if it is shown all other assets and loans available
to an individual are first exhausted.  The following checklist will aid you in
determining whether or not you are eligible to apply for a Financial Hardship
Withdrawal.


INSTRUCTIONS:

Answer the following questions to determine if you may apply for a Financial
Hardship Withdrawal.

Yes  No
         1. Are you eligible for a loan or "regular" withdrawal through TIP
            that satisfies the Financial Hardship request?   Amount $__________.
               See page two of your most recent TIP statement.


         2. Will you receive any reimbursement or compensation from insurance?
            Amount $__________.  Note:  If payment is required to obtain
            medical treatment, you may also be able to receive a withdrawal.


         3. Can the Financial Hardship be satisfied by liquidating assets
            of you, and/or your spouse and children?   Amount $__________.


         4. Are you able to obtain a loan from commercial sources? Amount
            $__________.


         5. Can the Financial Hardship be satisfied by ceasing contributions
            to TIP?   Amount $___________.

If you answered "yes" to any of the questions, you are ineligible for a
Financial Hardship unless the full amount of the Financial Hardship cannot be
satisfied by exhausting the funds available through numbers 1-5 above.  If these
measures are pursued completely and the Financial Hardship is still not
satisfied, you will need to complete a TIP Financial Hardship Application and
Personal Financial Statement, in addition to supplying accompanying
documentation.  Questions may be directed to Denise Freedman, ext. 4416, or
Debra Rock, ext. 7613.

Under IRS Financial Hardship Withdrawal guidelines, it must be demonstrated that
a hardship situation cannot be satisfied through depletion of assets and other
sources, including borrowing from a commercial source.  In order to consider a
request for Financial Hardship, proof of a loan denial from a lending
institution must be provided.  Please check one of the boxes below


         I have enclosed a Statement of Credit Denial for $_____________
         from _________________________________.  (A bank, credit union, finance
         company, or other financial institution.)


         I have secured a loan of $______________ to partially meet this
         Financial Hardship but was unable to borrow the full amount.  (You must
         include a copy of the loan note.)


         I have not applied for a commercial loan.

         ______  1.  I will apply for a loan of $____________ with a commercial
                 lender other than The Northern Trust.

         ______  2.  I authorize the Benefits Division to forward my completed
                 Personal Financial Statement to the Employee Loan Division
                 of The Northern Trust and obtain any credit reports
                 necessary to determine if I am eligible to apply for a loan
                 of $_____________.  I realize I must complete additional loan
                 forms for a Northern loan to be initiated.  To expedite this
                 request, I authorize Employee Loans to forward any Statement
                 of Credit Denial Directly to the TIP Administrator, M-8.


I understand that failure to provide a statement of Credit Denial will be reason
for denial of TIP Financial Hardship funds.

                               TAX CONSIDERATIONS


NAME: _______________________________  SOC. SEC. #: ____________________________


The taxable portion of your withdrawal is subject to an automatic 20% Federal
income tax withholding on any amount that is not directly rolled over to an IRA
or another Employer's Plan.  The non-taxable part of your withdrawal is not
subject to tax withholding and cannot be transferred to an IRA or Employer's
Plan.  If you do not make a tax election, the 20% withholding will automatically
apply.  Please see the (Special Tax Notice, In-Service Withdrawals) attached 
to this form for a more detailed explanation.

NOTE:  To qualify for a Swing Loan from Employee Banking, the distribution must
     be payable to you and tax withholding will apply.

          Distribute my entire taxable withdrawal amount in a check payable to
          me. I understand that 20% of the taxable portion of the distribution
          will be withheld in Federal taxes.

          Rollover 100% of my taxable distribution to the IRA account/Employer
          Plan below.  I will withdraw the fund from this account/plan to meet
          the financial hardship need indicated in this application.

          Rollover $____________ of my taxable distribution and make the balance
          payable to me.  I understand that I must withdraw the funds from the
          account/plan to meet the financial hardship need indicated in this
          application and that 20% of the taxable balance paid to me will be
          withheld in taxes.

Direct Rollover My Funds to:
- --------------------------- 

Financial Institution/Employer Plan: ___________________________________________

Address: _______________________________________________________________________

Account Number: ________________________________________________

Your check will be made payable to this IRA account/Employer Plan and mailed to
you for deposit.


                        STATEMENT OF TRUTH AND ACCURACY

I have made every attempt to provide complete and accurate information on this
application.  I understand that any intentional misrepresentation of facts or
circumstances relating to this Financial Hardship Withdrawal Application or the
intentional withholding of relevant information is a major violation of Bank
policy and will result in disciplinary action and could lead to termination of
employment.

                               SPECIAL TAX NOTICE
                        IN-SERVICE WITHDRAWALS FROM TIP


This notice contains important information you will need before you decide how
to receive your payment from the Thrift Incentive Plan. (TIP)

                                    SUMMARY

A payment from TIP that is eligible for "rollover" can be taken in two ways.
You can have all or any portion of your payment either
     1) PAID IN A "DIRECT ROLLOVER"
     2) PAID TO YOU

A rollover is a payment of your TIP benefits to your individual retirement
arrangement (IRA) or to another employer's plan.  This choice will affect the
tax you owe.

  If you choose a DIRECT ROLLOVER:

     Your payment will not be taxed in the current year and no income tax will
     be withheld.
     Your payment will be made directly to your IRA or other employer's plan.
     Your payment will be taxed later when you take it out of the IRA or other
     employer's plan.

  If you choose to have your TIP Benefits PAID TO YOU:

     You will receive only 80% of the payment, because The Northern Trust is
     required to withhold 20% of the payment and send it to the IRS as income
     tax withholding to be credited against your taxes.

     Your payment will be taxed in the current year unless you roll it over.  
     You may be able to use special tax rules that could reduce the tax you owe.
     (see pg. 4)  However, if you receive the payment before age 59 1/2, you
     also may have to pay an additional 10% tax.

     You can roll over the payment to your IRA or another employer's plan within
     60 days of receiving the payment.  The amount rolled over will not be taxed
     until you take it out of the IRA or employer's plan.

     If you want to roll over 100% of the payment to an IRA or another
     employer's plan, you must find other money to replace the 20% that was
     withheld.  If you roll over only the 80% that you received, you will be
     taxed on the 20% that was withheld and that is not rolled over.

     NOTE:
     Although taxable funds that come out of TIP as an in-service withdrawal-are
     eligible for rollover, the funds will not be accepted for rollover back 
     into TIP.

</TABLE>

                  PAYMENTS THAT CAN AND CANNOT BE ROLLED OVER

Payments from TIP may be "eligible rollover distributions." This means that they
can be rolled over to an IRA or another employer's plan.  In general, any
payment from TIP (including an in-service withdrawal) is considered an eligible
rollover distribution, EXCEPT for the following types of payments which CANNOT
be rolled over:

NON-TAXABLE PAYMENTS
   In general, only the "taxable portion" of your payment is an eligible
   rollover distribution.  If you have made "after-tax" employee contributions
   to TIP, these contributions will be non-taxable when they are paid to you,
   and they cannot be rolled over.

                                       7
<PAGE>

REQUIRED MINIMUM PAYMENTS
   Beginning in the year you reach age 70 1/2, you are required to take an
   annual distribution from TIP.  These required minimum distributions cannot be
   rolled over.


                                DIRECT ROLLOVER

You can choose a direct rollover of all or any portion of your payment that is
an "eligible rollover distribution," as described above.  In a direct rollover,
the eligible rollover distribution is made payable directly from TIP to an IRA
or another employer's plan.  If you choose a direct rollover, you are not taxed
on a payment until you later take it out of the IRA or employer's plan.


DIRECT ROLLOVER TO AN IRA
   You can open an IRA to receive the direct rollover. (The term "IRA" as used
   in this notice includes individual retirement accounts and individual
   retirement annuities.) If you choose to have your payment made directly to an
   IRA, contact an IRA sponsor (usually a financial institution) to obtain an
   account number.  Supply the name of the institution and the account number on
   your withdrawal form.  The check will then be made payable to the IRA and
   sent to you for delivery to the IRA institution.

DIRECT ROLLOVER TO ANOTHER EMPLOYER'S PLAN
   If you are employed by a new employer that has a plan, and you want a direct
   rollover to that plan, ask the administrator of that plan whether it will
   accept your rollover. If the plan will accept your rollover, supply the name
   of the plan and the company name on your distribution or withdrawal form.  An
   employer plan is not legally required to accept a rollover.  If your new
   employer's plan does not accept a rollover, you can choose a direct rollover
   to an IRA.

   PLEASE NOTE:
      Although taxable funds that come out of TIP as an in-service withdrawal
      are eligible for rollover, the funds will not be accepted for rollover
      back into TIP.


                          PAYMENT MADE PAYABLE TO YOU

If you have the payment made to you, it is subject to 20% income tax
withholding.  The payment is taxed in the year you receive it unless, within 60
days, you roll it over to an IRA or another plan that accepts rollovers.  If you
do not roll it over, special tax rules may apply.

MANDATORY TAX WITHHOLDING
   If any portion of the payment to you is an eligible rollover distribution, 
   TIP is required by law to withhold 20% of that amount.  This amount is sent 
   to the IRS as income tax withholding.  For example, if your eligible 
   rollover distribution is $10,000, only $8,000 will be paid to you because 
   TIP must withhold $2,000 as income tax.  However, when you prepare  your
   income tax return for the year, you will report the full $10,000 as a 
   payment from TIP.  You will report the $2,000 as tax withheld, and it will be
   credited against any income tax you owe for the year.
   
SIXTY-DAY ROLLOVER OPTION
   If you have an eligible rollover distribution paid to you, you can still
   decide to roll over all or part of it to an IRA or another employer's plan.  
   If you decide to roll over, you must make the rollover within 60 days after 
   you receive the payment.  The portion of your payment that is rolled over 
   will not be taxed until you take it out of the IRA or employer's plan. 
 
   You can roll over up to 100% of the eligible rollover distribution, 
   including an amount equal to the 20% that was withheld.  If you choose to 
   roll over 100%, you must find other money within the 60-day period to 
   contribute to the IRA or employer's plan to replace the 20% that was        
   withheld.  On the other hand, if you roll over only the 80% that you 
   received, you will be taxed on the 20% that was withheld.

                                       8
<PAGE>

   EXAMPLE:
      Your eligible rollover distribution is $ 10,000, and you choose to have it
      paid to you.  You will receive $8,000, and $2,000 will be sent to the IRS
      as income tax withholding.  Within 60 days after receiving the $8,000, you
      may roll over the entire $10,000 to an IRA or employer's plan.  To do
      this, you roll over the $8,000 you received from TIP, and you will have to
      find $2,000 from other sources (your savings, a loan, etc.). In this case,
      the entire $10,000 is not taxed until you take it out of the IRA or
      employer's plan. If you roll over the entire $10,000, when you file your
      income tax return, you may get a refund of the $2,000 withheld.

If, on the other hand, you roll over only $8,000, the $2,000 you did not roll
over is taxed in the year it was withheld.  When you file your income tax return
you may get a refund of part of the $2,000 withheld. (However, any refund is
likely to be larger if you roll over the entire $10,000.)

ADDITIONAL 10% TAX IF YOU ARE UNDER AGE 59 1/2
If you receive a payment before you reach age 59 1/2 and you do not roll it
over, then, in addition to the regular income tax, you may have to pay an extra
tax equal to 10% of the taxable portion of the payment.  The additional 10% tax
does not apply to your in-service withdrawal if it is (see IRS Form 5329 for
more information on the additional 10%):

      Used to pay certain medical expenses
      Paid to you under a Qualified Domestic Relations Order

SPECIAL TAX TREATMENT
If your eligible rollover distribution is not rolled over, it will be taxed in
the year you receive it.  However, if it qualifies as a "lump sum distribution",
it may be eligible for special tax treatment.  A lump sum distribution is a
payment, within one year, of your entire balance under TIP, ESOP and the Pension
Plan that is payable to you because you have reached age 59 1/2 or separated
from service with your employer.  For a payment to qualify as a lump sum
distribution, you must have been a participant in the plan for at least 5 years.
The special tax treatment for lump sum distributions is described below.

FIVE-YEAR AVERAGING
If you receive a lump sum distribution after you are age 59 1/2, you may be able
to make a one-time election to figure the tax on the payment by using "5-year
averaging." Five-year averaging often reduces the tax you owe because it treats
the payment as if it were paid over 5 years.

TEN-YEAR AVERAGING IF YOU WERE BORN BEFORE JANUARY 1, 1936
If you receive a lump sum distribution and you were born before January 1, 1936,
you can make a one-time election to figure the tax on the payment by using "10-
year averaging" (using 1986 tax rates).  Like the 5-year averaging rules, 10-
year averaging often reduces the tax you owe.

CAPITAL GAINS TREATMENT IF YOU WERE BORN BEFORE JANUARY 1, 1936
In addition, if you receive a lump sum distribution and you were born before
January 1, 1936, you may elect to have the part of your payment that is
attributable to your pre-1974 participation in the retirement plans (if any)
taxed as long-term capital gain at a rate of 20%.

There are other limits on the special tax treatment for lump sum distributions.
For example, you can generally elect this special tax treatment only once in
your lifetime, and the election applies to all lump sum distributions you
receive in that same year.  If you have previously rolled over a payment from
the Plan, you cannot use this special tax treatment for later payments from TIP.
If you roll over your payment to an IRA, you will not be able to use this
special tax treatment for later payments from the IRA.  Also, if you roll over
only a portion of your payment to an IRA, this special tax treatment is not
available for the rest of the payment.  Additional restrictions are described in
IRS Form 4972, which has more information on lump sum distributions and how you
elect the special tax treatment.

             PAYMENTS UNDER A "QUALIFIED DOMESTIC RELATIONS ORDER"

In general the rules summarized above that apply to payments to employees also
apply to payments to alternate payees under a "Qualified Domestic Relations
Order" (QDOR) in connections with a divorce or legal separation.

If you are an alternate payee, you may choose to have an eligible rollover
distribution paid in a direct rollover to an IRA or paid to you.  Your payment
is not subject to the additional 10% tax described above, even if you are
younger than age 59 1/2 and you may be able to use the special tax treatment for
lump sum distributions and distributions in employer stock also described above.

                      HOW TO OBTAIN ADDITIONAL INFORMATION

This notice summarizes only the federal (not state or local) tax rules that
might apply to your payment.  The rules described above are complex and contain
many conditions and exceptions that are not included in this notice.  Therefore,
you may want to consult with a professional tax advisor before you take payment
of your benefits from TIP.  Also, you can find more specific information on the
tax treatment of payments from qualified retirement plans in IRS Publication
575, PENSION AND ANNUITY INCOME, and IRS Publication 590, INDIVIDUAL RETIREMENT
ARRANGEMENTS.  These publications are available from your local IRS office or by

                              SPECIAL TAX NOTICE
                         IN-SERVICE WITHDRAWALS FROM TIP
This notice contains important information you will  need before you decide how
to receive your payment from the Thrift-Incentive Plan. (TIP)

                                     SUMMARY
A payment from TIP that is eligible for "rollover" can be taken in two ways. You
can have all or any portion of your payment either
  1) PAID IN A "DIRECT ROLLOVER" 
  2) PAID TO YOU
  
A rollover is a payment of your TIP benefits to your individual retirement
arrangement (IRA) or to another employer's plan. This choice will affect the
tax you owe.

  If you choose a DIRECT ROLLOVER:
    . Your payment will not be taxed in the current year and no income tax will
      be withheld.

    . Your payment will be made directly to your IRA or other employer's plan.

    . Your payment will be taxed later when you take it out of  the IRA or other
      employer's plan.
 
  If you choose to have your TIP Benefits PAID TO YOU:
    . You will receive only 80% of the payment, because the Northern Trust is
      required to withhold 20% of the payment  and send it to the IRS as income
      tax withholding to be  credited against your taxes.

    . Your payment will be taxed in the current year unless you roll it over.
      You may be able to use special tax rules that  could reduce the tax you
      owe. (see pg. 4) However, if you  receive the payment before age 59 1/2,
      you also may have to  pay an additional 10% tax.

     . You can roll over the payment to your IRA or another employer's plan
       within 60 days of receiving the payment.  The amount rolled over will not
       be taxed until you take it  out of the IRA or employer's plan.

     . If you want to roll over 100% of the payment to an IRA or another
       employer's plan, you must find other money to  replace the 20% that was
       withheld. If you roll over only the 80% that you received, you will be
       taxed on the 20%  that was withheld and that is not rolled over. 

       NOTE:
       Although taxable funds that come out of TIP as an  in-service withdrawal
       are eligible for rollover, the funds  will not be accepted for rollover
       back into TIP.

                  PAYMENTS THAT CAN AND CANNOT BE ROLLED OVER
Payments from TIP may be "eligible rollover  distributions." This means that
they can be rolled  over to an IRA or another employer's plan. In general, any
payment from TIP (including an  in-service withdrawal) is considered an eligible
rollover distribution, EXCEPT for the following types of payments which CANNOT
be rolled over: 

Non-taxable Payments 
  In general, only the "taxable portion" of your payment is an  eligible
  rollover distribution. If you have made "after-tax"  employee contributions to
  TIP, these contributions will be  non-taxable when they are paid to you, and
  they cannot be  rolled over. 
 
Required Minimum Payments 
  Beginning in the year you reach age 70 1/2, you are required to  take an
  annual distribution from TIP. These required minimum  distributions cannot be
  rolled over.
  
                                DIRECT ROLLOVER
You can choose a direct rollover of all or any  portion of your payment that is
an "eligible  rollover distribution," as described above. In a  direct rollover,
the eligible rollover distribution  is made payable directly from TIP to an IRA
or  another employer's plan. If you choose a direct  rollover, you are not taxed
on a payment until you  later take it out of the IRA or employer's plan. 

                                       1
<PAGE>
 
DIRECT ROLLOVER TO AN IRA 
  You can open an IRA to receive the direct rollover. (The term  "IRA" as used
  in this notice, includes individual retirement accounts and individual
  retirement annuities.) If you choose to  have your payment made directly to an
  IRA, contact an IRA  sponsor (usually a financial institution) to obtain an
  account number. Supply the name of the institution and the account number on
  your withdrawal form. The check will then be made  payable to the IRA and sent
  to you for delivery to the IRA  institution. 

DIRECT ROLLOVER TO ANOTHER EMPLOYER'S PLAN 
  If you are employed by a new employer that has a plan, and you  want a direct
  rollover to that plan, ask the administrator of  that plan whether it will
  accept your rollover. If the plan  will accept your rollover, supply the name
  of the plan and the  company name on your distribution or withdrawal form. An 
  employer plan is not legally required to accept a rollover. If  your new
  employer's plan does not accept a rollover, you can  choose a direct rollover
  to an IRA. 
  
    PLEASE NOTE: 
      Although taxable funds that come out of TIP as an  in-service withdrawal
      are eligible for rollover, the funds will not be accepted for rollover
      back into TIP.

                           PAYMENT MADE PAYABLE TO YOU
If you have the payment made to you, it is subject  to 20% income tax
withholding. The payment is taxed  in the year you receive it unless, within 60
days,  you roll it over to an IRA or another plan that  accepts rollovers. If
you do not roll it over,  special tax rules may apply. 

MANDATORY TAX WITHHOLDING 
  If any portion of the payment to you is an eligible rollover  distribution,
  TIP is required by law to withhold 20% of that  amount. This amount is sent to
  the IRS as income tax  withholding. For example, if your eligible rollover 
  distribution is $10,000, only $8,000 will be paid to you  because TIP must
  withhold $2,000 as income tax. However, when  you prepare your income tax
  return for the year, you will  report the full $10,000 as a payment from TIP.
  You will report  the $2,000 as tax withheld, and it will be credited against
  any  income tax you owe for the year. 
  
SIXTY-DAY ROLLOVER OPTION 
  If you have an eligible rollover distribution paid to you, you  can still
  decide to roll over all or part of it to an IRA or  another employer's plan.
  If you decide to roll over, you must  make the rollover within 60 days after
  you receive the payment.  The portion of your payment that is rolled over will
  not be  taxed until you take it out of the IRA or employer's plan. 

  You can roll over up to 100% of the eligible rollover  distribution, including
  an amount equal to the 20% that was  withheld. If you choose to roll over
  100%, you must find other  money within the 60-day period to contribute to the
  IRA or  employer's plan to replace the 20% that was withheld. On the  other
  hand, if you roll over only the 80% that you received,  you will be taxed on
  the 20% that was withheld.
 
     EXAMPLE: 
       Your eligible rollover distribution is $10,000, and you  choose to have
       it paid to you. You will receive $8,000, and  $2,000 will be sent to the
       IRS as income tax withholding.  Within 60 days after receiving the
       $8,000, you may roll over the entire $10,000 to an IRA or employer's
       plan. To do  this, you roll over the $8,000 you received from TIP, and 
       you will have to find $2,000 from other sources (your savings, a loan,
       etc.). In this case, the entire $10,000 is  not taxed until you take it
       out of the IRA or employer's  plan. If you roll over the entire $10,000,
       when you file  your income tax return you may get a refund of the $2,000 
       withheld. 

  If on the other hand, you roll over only $8,000, the $2,000 you  did not roll
  over is taxed in the year it was withheld. When  you file your income tax
  return you may get a refund of part of  the $2,000 withheld. (However, any
  refund is likely to be  larger if you roll over the entire $10,000) 
 
ADDITIONAL 10% TAX IF YOU ARE UNDER AGE 59 1/2 
If you receive a payment before you reach age 59 1/2 and you do not roll it
over, then, in addition  to the regular income tax, you may have to pay an 
extra tax equal to 10% of the taxable portion of the payment. The additional
10% tax does not apply  to your in-service withdrawal if it is (see IRS Form
5329 for more information on the additional 10%):

     . Used to pay certain medical expenses 

     . Paid to you under a Qualified Domestic Relations Order
         
SPECIAL TAX TREATMENT
If your eligible rollover distribution is not  rolled over, it will be taxed in
the year you  receive it. However, if it qualifies as a "lump sum  distribution"
it may be eligible for special tax  treatment. A lump sum distribution is a
payment,  within one year, of your entire balance under TIP, ESOP and the
Pension Plan that is payable to you  because you have reached age 59 1/2 or
separated  from service with your employer. For a payment to  qualify as a lump
sum distribution, you must have  been a participant in the plan for at least 5 
years. The special tax treatment for lump sum distributions is described below. 

                                       2
<PAGE>
 
FIVE-YEAR AVERAGING 
  If you receive a lump sum distribution after you are age 59 1/2, you may be
  able to make a one-time election to figure the  tax on the payment by using
  "5-year averaging." Five-year  averaging often reduces the tax you owe because
  it treats the  payment as if it were paid over 5 years.
  
TEN-YEAR AVERAGING IF YOU WERE BORN BEFORE JANUARY 1, 1936 
  If you receive a lump sum distribution and you were born before January 1,
  1936, you can make a one-time election to figure the  tax on the payment by
  using "10-year averaging" (using 1986 tax  rates). Like the 5-year averaging
  rules, 10-year averaging  often reduces the tax you owe. 

CAPITAL GAINS TREATMENT IF YOU WERE BORN BEFORE JANUARY 1, 1936 
  In addition, if you receive a lump sum distribution and you were born before
  January 1, 1936, you may elect to have the  part of your payment that is
  attributable to your pre-1974  participation in the retirement plans (if any)
  taxed as  long-term capital gain at a rate of 20%. 

  There are other limits on the special tax treatment for lump  sum
  distributions. For example, you can generally elect this special tax
  treatment only once in your lifetime and the  election applies to all lump sum
  distributions you receive in  that same year. If you have previously rolled
  over a payment  from the Plan, you cannot use this special tax treatment for 
  later payments from TIP. If you roll over your payment to an IRA, you will
  not be able to use this special tax treatment for later payments from the
  IRA. Also, if you roll over only a portion of your payment to an IRA, this
  special tax treatment  is not available for the rest of the payment.
  Additional  restrictions are described in IRS Form 4972, which has more 
  information on lump sum distributions and how you elect the special tax
  treatment.

             PAYMENTS UNDER A "QUALIFIED DOMESTIC RELATIONS ORDER"
 
In general the rules summarized above that apply to payments to employees also
apply to payments to  alternate payees under a "Qualified Domestic Relations
Order" (QDRO) in connection with a  divorce or legal separation. 

If you are an alternate payee, you may choose to  have an eligible rollover
distribution paid in a  direct rollover to an IRA or paid to you. Your  payment
is not subject to the additional 10% tax  described above, even if you are
younger than age  59 1/2 and you may be able to use the special tax  treatment
for lump sum distributions and  distributions in employer stock also described 
above.

                     HOW TO OBTAIN ADDITIONAL INFORMATION
This notice summarizes only the federal (not state  or local) tax rules that
might apply to your  payment. The rules described above are complex and contain
many conditions and exceptions that are not  included in this notice. Therefore,
you may want to  consult with a professional tax advisor before you take
payment of your benefits from TIP. Also, you can find more specific information
on the tax  treatment of payments from qualified retirement plans in IRS
Publication 575, Pension and Annuity  Income, and IRS Publication 590,
Individual  Retirement Arrangements. These publications are available from your
local IRS office or by calling  1-800-TAX-FORMS.

                              SPECIAL TAX NOTICE
               REGARDING DISTRIBUTIONS FROM TIP, ESOP AND PENSION 

This notice contains important information you will need before you decide how
to receive your payment from the Thrift-Incentive Plan, the Employee Stock 
Ownership Plan, or the Pension Plan (the Plans).

                                     SUMMARY

A payment from the Plans that is eligible for "rollover" can be taken in two
ways. You can have all or any portion of your payment either
   1) PAID IN A "DIRECT ROLLOVER" 
   2) PAID TO YOU

A rollover is a payment of your Plan benefits to your individual retirement 
arrangement (IRA) or to another employer plan. This choice will affect the tax 
you owe.

  If you choose a DIRECT ROLLOVER:
     . Your payment will not be taxed in the current year and no income tax
       will be withheld.
     . Your payment will be made directly to your IRA or, if you choose, to
       another employer plan that accepts your rollover.
     . Your payment will be taxed later when you take it out of the IRA or the
       employer plan. 

  If you choose to have your Plan benefits PAID TO YOU:
     . You will receive only 80% of the payment, because the Northern Trust is
       required to withhold 20% of the payment and send it to the IRS as
       income tax withholding to be credited against your taxes.
     . Your payment will be taxed in the current year unless you roll it over.
       You may be able to use special tax rules that could reduce the tax you
       owe. (see pg. 3) However, if you receive the payment before age 59 1/2,
       you also may have to pay an additional 10% tax.
     . You can roll over the payment to your IRA or to another employer plan
       that accepts your rollover within 60 days of receiving the payment. The
       amount rolled over will not be taxed until you take it out of the IRA
       or employer plan.
     . If you want to roll over 100% of the payment to an IRA or an employer
       plan, you must find other money to replace the 20% that was withheld.
       If you roll over only the 80% that you received, you will be taxed on
       the 20% that was withheld and that is not rolled over.

     NOTE:
       Although funds that come out of TIP as an in-service withdrawal are
       eligible for rollover, the funds will not be accepted for rollover back
       into TIP.

                               MORE INFORMATION

                                                                    Page

                  PAYMENTS THAT CAN AND CANNOT BE ROLLED OVER

Payments from the Plans may be "eligible rollover distributions." This means
that they can be rolled over to an IRA or another employer plan that accepts
rollovers. In general, any payment from the Plans (including an in-service
withdrawal) is considered an eligible rollover distribution, EXCEPT for the
following types of payments which CANNOT be rolled over: 

Non-taxable Payments
 
  In general, only the "taxable portion" of your payment is an eligible 
  rollover distribution. If you have made "after-tax" employee contributions 
  to the Plans, these contributions will be non-taxable when they are paid to 
  you, and they cannot be rolled over.

Required Minimum Payments

  Beginning in the year you reach age 70 1/2, you are required to take an
  annual distribution from each plan. These required  minimum distributions
  cannot be rolled over.

<PAGE>

Monthly Payments From the Pension Plan 

  You cannot roll over monthly annuity payments you receive from the Pension
  Plan. These payments are part of a series of equal (or almost equal) payments
  that are made at least once a year and that will last for your lifetime, you
  and your beneficiary's lifetimes or a period of ten years or more. 

ESOP Dividend Payments 

  The dividend check you receive each November from the ESOP cannot be rolled
  over and is considered taxable income in the year you receive it.

                                DIRECT ROLLOVER

You can choose a direct rollover of all or any portion of your payment that is
an "eligible rollover distribution," as described above. In a direct rollover,
the eligible rollover distribution is made payable directly from the Plan to
an IRA or another employer plan that accepts rollovers. If you choose a direct
rollover, you are not taxed on a payment until you later take it out of the IRA
or the employer plan.

Direct Rollover to an IRA

  You can open an IRA to receive the direct rollover. (The term "IRA" as used in
  this notice, includes individual retirement accounts and individual
  retirement annuities.) If you choose to have your payment made directly to
  an IRA, contact an IRA sponsor (usually a financial institution) to obtain
  an account number. Supply the name of the institution and the account number
  on your distribution or withdrawal form. The check and or shares of stock
  will then be made payable to the IRA and sent to you for delivery to the IRA
  institution. 

Direct Rollover to a Plan 

  If you are employed by a new employer that has a plan, and you want a direct
  rollover to that plan, ask the administrator of that plan whether it will
  accept your rollover. If the plan will accept your rollover, supply the name
  of the plan and the company name on your distribution or withdrawal form. An 
  employer plan is not legally required to accept a rollover. If your new
  employer's plan does not accept a rollover, you can choose a direct rollover
  to an IRA.

  Please Note: Although, taxable funds that come out of TIP as an in-service
  withdrawal are eligible for rollover, the funds will not be accepted for
  rollover back into TIP. 

                          PAYMENT MADE PAYABLE TO YOU

If you have the payment made to you, it is subject to 20% income tax 
withholding. The payment is taxed in the year you receive it unless, within 60 
days,you roll it over to an IRA or another plan that accepts rollovers. If you 
do not roll it over, special tax rules may apply. 

Mandatory Tax Withholding  

  If any portion of the payment to you is an eligible rollover distribution, 
  the Plans are required by law to withhold 20% of that amount. This amount is 
  sent to the IRS as income tax withholding. For example, if your eligible 
  rollover distribution is $10,000, only $8,000 will be paid to you because the 
  Plan must withhold $2,000 as income tax. However, when you prepare your 
  income tax return for the year, you will report the full $10,000 as a payment 
  from the Plan. You will report the $2,000 as tax withheld, and it will be 
  credited against any income tax you owe for the year. 

Sixty-Day Rollover Option 

  If you have an eligible rollover distribution paid to you, you can still
  decide to roll over all or part of it to an IRA or another employer plan that
  accepts rollovers. If you decide to roll over, you must make the rollover
  within 60 days after you receive the payment. The portion of your payment that
  is rolled over will not be taxed until you take it out of the IRA or the
  employer plan. 

  You can roll over up to 100% of the eligible rollover distribution, including 
  an amount equal to the 20% that was withheld. If you choose to roll over 100%,
  you must find other money within the 60-day period to contribute to the IRA or
  the employer plan to replace the 20% that was withheld. On the other hand, if 
  you roll over only the 80% that you received, you will be taxed on the 20%
  that was withheld. 

     EXAMPLE: 
       Your eligible rollover distribution is $10,000, and you choose to have it
       paid to you. You will receive $8,000, and $2,000 will be sent to the IRS 
       as income tax withholding. Within 60 days after receiving the $8,000, you
       may roll over the entire $10,000 to an IRA or employer plan. To do this, 
       you roll over the $8,000 you received from the Plans, and you will have
       to find $2,000 from other sources (your savings, a loan, etc.). In this
       case,  the entire $10,000 is not taxed until you take it out of the IRA
       or employer plan. If you roll over the entire $10,000, when you file
       your income tax return you may get a refund of the $2,000 withheld. 

       If on the other hand, you roll over only $8,000, the $2,000 you did not 
       roll over is taxed in the year it was withheld. When you file your income
       tax return you may get a refund of part of the $2,000 withheld. (However,
       any refund is likely to be larger if you roll over the entire $10,000.) 
<PAGE>
Additional 10% Tax If You Are Under Age 59 1/2 

  If you receive a payment before you reach age 59 1/2 and you do not roll it 
  over, then, in addition to the regular income tax, you may have to pay an 
  extra tax equal to 10% of the taxable portion of the payment. The additional 
  10% tax does not apply to your payment if it is (see IRS Form 5329 for more 
  information on the additional 10%):

     . Paid to you because you separate service with your employer during or 
       after the year you reach age 55 

     . Paid because you retire due to disability 

     . Paid to you as equal (or almost equal) payments over your life or life 
       expectancy

     . Used to pay certain medical expenses 

     . Paid to you as the beneficiary of the employee 

     . Paid to you under a Qualified Domestic Relations Order.

Special Tax Treatment

If your eligible rollover distribution is not rolled over, it will be taxed in 
the year you receive it. However, if it qualifies as a "lump sum distribution" 
it may be eligible for special tax treatment. A lump sum distribution is a 
payment, within one year, of your entire balance under the Plans that is 
payable to you because you have reached age 59 1/2 or separated from service 
with your employer. For a payment to qualify as a lump sum distribution, you 
must have been a participant in the Plan for at least 5 years. Prior to the 
year of distribution, the special tax treatment for lump sum distributions is 
described below.

Five-Year Averaging

  If you receive a lump sum distribution after you are age 59 1/2, you may be 
  able to make a one-time election to figure the tax on the payment by using 
  "5-year averaging." Five-year averaging often reduces the tax you owe because 
  it treats the payment much as if it were paid over 5 years.

Ten-Year Averaging If You Were Born Before January 1, 1936 

  If you receive a lump sum distribution and you were born before January 1, 
  1936, you can make a one-time election to figure the tax on the payment by 
  using "10-year averaging" (using 1986 tax rates). Like the 5-year averaging 
  rules, 10-year averaging often reduces the tax you owe. 

Capital Gains Treatment If You Were Born Before January 1, 1936 

  In addition, if you receive a lump sum distribution and you were born before 
  January 1, 1936, you may elect to have the part of your payment that is 
  attributable to your pre-1974 participation in the Plans (if any) taxed as 
  long term capital gain at a rate of 20%. 

  There are other limits on the special tax treatment for lump sum 
  distributions. For example, you can generally elect this special tax 
  treatment only once in your lifetime and the election applies to all lump 
  sum distributions you receive in that same year. If you have previously 
  rolled over a payment from the Plans, you cannot use this special tax 
  treatment for later payments from the Plans. If you roll over your payment to 
  an IRA, you will not be able to use this special tax treatment for later 
  payments from the IRA. Also, if you roll over only a portion of your payment 
  to an IRA, this special tax treatment is not available for the rest of the 
  payment. Additional restrictions are described in IRS Form 4972, which has 
  more information on lump sum distributions and how you elect the special tax 
  treatment. 

Employer Stock or Securities 

  There is a special tax rule that applies to distributions of Northern Trust 
  Common Stock from ESOP and from TIP Fund D. To use this special rule, the 
  payment must qualify as a lump sum distribution, as described above (except 
  that you do not have to have 5 years participation in the plan). Under this 
  special rule, you may have the option of not paying tax on the "net 
  unrealized appreciation" of the stock until you sell the stock. Net 
  unrealized appreciation generally is the increase in the value of the 
  employer stock while it was held by the Plans. For example, if the stock was 
  worth $1,000 when it was contributed to the Plan, but it was worth $1,200 
  when you received it, you would not have to pay tax on the $200 increase in 
  value until you later sold the stock.

  The stock can be rolled over to an IRA or another employer plan either in a 
  direct rollover or a rollover that you make yourself. If you choose to have 
  your shares registered in your name, rather than directly transferred, the 
  Plans are required by law to withhold 20% of the cost basis of the shares in 
  income taxes. However, the taxes will be withheld only to the extent there is 
  cash available in the distribution. Shares will not be sold to satisfy the 
  withholding requirement. See "Payment Paid To You" for more details on how 
  the withholding works. The special tax treatment options described above may 
  also apply to shares that are not rolled over.
<PAGE>
                         OUTSTANDING TIP LOAN BALANCES

A loan from TIP is not considered a taxable payment unless the entire balance 
is not repaid to the plan. 

Active Employees 

  If a loan amount is not repaid and is declared defaulted while you are 
  employed, the defaulted amount that was originally from taxable funds, is 
  reported as a taxable loan distribution. The taxable loan distribution is not 
  subject to the 20% withholding and is not eligible for rollover. 

Terminated Employees 

  If a loan is not repaid in full by the end of the calendar quarter in which 
  you terminate, the remaining balance that originally came from taxable funds, 
  will be taxable.

  The election you make regarding the payment of your remaining account balances
  will determine the tax withholding on the taxable loan distribution amount.

        SURVIVING SPOUSES, ALTERNATIVE PAYEES, AND OTHER BENEFICIARIES 

In general the rules summarized above that apply to payments to employees also 
apply to spouses and former spouses who receive payments on account of an 
employee's death under a "Qualified Domestic Relations Order". Some of the 
rules summarized above also apply to a deceased employee's beneficiary who is 
not a spouse. 

If you are a spouse or former spouse who receive a payment under the Qualified 
Domestic Relations Order, you may choose to have an eligible rollover 
distribution paid in a direct rollover to an IRA or paid to you. If you are a 
beneficiary other than the surviving spouse, you cannot choose a direct 
rollover, and you cannot roll over the payment yourself. 

If you are a surviving spouse, an alternate payee, or another beneficiary, 
your payment is not subject to the additional 10% tax described above, even if 
you are younger than age 59 1/2 and you may be able to use the special tax 
treatment for lump sum distributions and distributions in employer stock also 
described above.

                      HOW TO OBTAIN ADDITIONAL INFORMATION

This notice summarizes only the federal (not state or local) tax rules that 
might apply to your payment. The rules described above are complex and contain 
many conditions and exceptions that are not included in this notice. Therefore, 
you may want to consult with a professional tax advisor before you take payment 
of your benefits from the Plans. Also, you can find more specific information 
on the tax treatment of payments from qualified retirement plans in IRS 
Publication 575, Pension and Annuity Income, and IRS Publication 590, 
Individual Retirement Arrangements. These publications are available from your 
local IRS office or by calling 1-800-TAX-FORMS.

               THE NORTHERN TRUST COMPANY THRIFT-INCENTIVE PLAN

                        LOAN ADMINISTRATION GUIDELINES

LOANABLE AMOUNTS

You may apply to borrow against your vested balance in TIP. The amount of funds 
which can be borrowed will be based on the following IRS Tax Reform limits.

            Value of Your Vested           Maximum
            Account Balance                Loan Amount*
            --------------------           ------------

            Less than $100,000             50% of Your Vested Account Balance  
            More than $100,000             $50,000    

  *If you currently have a loan outstanding, or had a loan outstanding within
   the previous 12 months, you will find your maximum loanable amount stated on
   page 2 of your most recent TIP statement. The maximum amount is calculated
   as the lessor of: 
   -------------

    1. 50% (your vested account balance + your outstanding loan balance)-your  
       outstanding loan balance, or

    2. $50,000 less your highest outstanding loan balance during the last 12 
       months.

HOW LOAN MONEY IS DISBURSED

When you take a loan, the money will be disbursed from your accounts in the 
following order until the respective funds are depleted.

            TIP Account                    Order of Loans

LOAN APPROVAL CRITERIA
- ----------------------

Approval of loan applications will be based on the following criteria:

1. The loan application is completed and submitted within the specified deadline
   dates.

2. If the loan is to exceed the 5-year period, a copy of the home purchase 
   contract must be submitted with the Loan Request form.

3. The loan amount requested is available and meets the IRS Tax Reform limits 
   shown above. (The amount available is reflected on page 2 of your quarterly
   TIP statement.)

4. Your net pay must be a minimum of $100.00 per pay period after the loan 
   repayment deduction is taken.

Your will receive written confirmation of receipt of your loan request.

LOAN REPAYMENT
- --------------

The term of the loan is determined by you and cannot exceed 60 months (except 
home loans which can be up to 180 months). Loans will be repaid via semi-monthly
payroll deductions for both principal and interest. Repayment will begin the pay
period immediately following payout of the loan.

If you do not have sufficient pay to deduct a payment, you are required to 
submit a personal check for the payment amount or an additional deduction amount
will be taken in a future pay period to collect the missed payment. If you are 
an active employee and receiving pay, but do not make a payment for a 90-day 
period, your loan will be defaulted and reported to the IRS as a taxable 
withdrawal. If you are on an unpaid leave of absence (including Long Term 
Disability and Family Care Leave) and do not make a payment for a one-year 
period, your loan will be defaulted and reported to the IRS as a taxable 
withdrawal. If you have a loan that is defaulted, you will be prohibited from 
taking a new loan for a two-year period.

PREPAYMENT OF AN OUTSTANDING LOAN
- ---------------------------------

Prepayment of a loan is permissible. The following administrative guidelines 
have been established:

   1. Prepayment may be for the total remaining principal balance only.
   
   2. Prepayment checks must be received a minimum of 6 business days prior to a
      payday in order to cease deductions on that payday.

   3. If your employment is terminated, you may repay the loan in full up to 5
      business days after the end of the processing cycle in which you
      terminate. (See Loan at Termination of Employment) 

Upon scheduled payoff or prepayment of an outstanding loan, one quarter must 
elapse before an application for a new loan can be made; if you have two loans 
outstanding, assuming Tax Reform rules/limits previously mentioned are met.

LOAN AT TERMINATION OF EMPLOYMENT A loan from TIP is not considered a taxable
- --------------------------------- 
payment unless the entire balance is not repaid to the plan.

Active Employees
  If a loan amount is not repaid and is declared defaulted while you are 
  employed, the defaulted amount that was originally from taxable funds is 
  reported as a taxable loan distribution. The taxable loan distribution is not 
  subject to the 20% withholding and is not eligible for rollover.

Terminated Employees
  If a loan is not repaid in full by the end of the calendar quarter in which 
  you terminate, the remaining balance that originally came from taxable funds 
  will be taxable as ordinary income and a 10% penalty tax may apply.

  The election you make regarding the payment of your remaining account balances
  will determine whether 20% tax withholding on the loan amount will be deducted
  from your distribution.

If there are any funds being paid to you, either before-tax funds that are not
directly rolled over or after-tax funds, 20% withholding on the loan amount will
be withheld from the check.

INTEREST RATES
- --------------
Rates will be established quarterly on the first day of the last month of the
quarter and will be announced in the Northern News at the next earliest date. 
The interest rate is based on the rate for a commercial loan secured by a 
savings account. The interest rate in effect at the time of the loan will be 
fixed for the entire term of the loan. All interest paid on a loan from TIP is 
credited back to your TIP account.

<PAGE>
CRITERIA FOR HOME LOAN - 61 TO 180 MONTHS OF PAYMENT
- ----------------------------------------------------

A home loan is considered a loan to purchase a single family principal 
residence. For purposes of IRS interest deductibility, a TIP loan is considered 
a personal loan, and not a mortgage. Refinancing of a principal residence and 
costs associated with remodeling or rehabilitation of your primary residence are
not acceptable home loan reasons. If a home loan is fully amortized and if you 
transfer title on the property, the loan will continue in effect until its 
maturity date.

APPLICATION PROCESS
- -------------------

You must complete a TIP Loan Request form, and forward it along with a copy of 
your most recent TIP statement to the TIP Administrator, M-8, no later than the 
15th day of the third month of the quarter. (March 15, June 15, September 15, 
December 15) Home loans requested in excess of 60 months require a residence 
purchase contract accompanying your request.

The Benefits Division will provide:

  * Promissory Note/Truth-in-Lending Statement

  * Amortization Schedule

Prior to release of the check, the Promissory Note must be signed and submitted 
to the Benefits Division before the loan check can be distributed to you. The 
Amortization Schedule will be sent to you with the TIP loan check.



For more information on TIP, see your Source Book or contact the TIP area at 
(312) 444-7613 or (312) 444-4416.

               THE NORTHERN TRUST COMPANY THRIFT-INCENTIVE PLAN

   Welcome to the Northern Trust Company! As a new employee you will soon be 
   eligible to participate in many of the Northern's excellent benefit 
   plans. One of these is the Thrift-Incentive Plan (TIP), a tax-qualified 
   savings/investment plan designed to encourage you to save for the future. 
   You will be eligible to join TIP the quarter following completion of one 
   year of service, provided you are age 21. 
    
   If you were a participant in a tax-qualified plan with a previous 
   employer, you may be eligible to "rollover" (deposit your pre-tax 
   distribution) into TIP. You may even rollover into TIP prior to becoming 
   an active plan member. Details describing the Rollover option are 
   attached. 

   TIP is one of your most valuable employee benefit plans, and is designed 
   to encourage you to save for the future. It offers a sound vehicle for 
   your long-term financial growth, as a savings/investment plan that both 
   you and the Bank can contribute to. 

   You can elect to make voluntary contributions to TIP between 1% and 12% 
   of your base salary. By contributing on a voluntary basis, you can 
   receive an additional matching contribution by the Bank, up to 5% of your 
   base salary, contingent upon the attainment of the Bank's earnings goal. 
   You can also choose how your contributions and the Bank contributions are 
   to be invested.

   You will be contacted approximately one month prior to the quarter you 
   become eligible to join TIP, and you will be invited to a presentation 
   detailing TIP. 

   If you have any questions about the Thrift-Incentive Plan or the TIP 
   Rollover Option, please contact the TIP area at 444-4416 or 444-7613.

                          THE NORTHERN TRUST COMPANY
                   THRIFT INCENTIVE PLAN ROLLOVER GUIDELINES

GENERAL ROLLOVER INFORMATION
   .  Rollovers are accepted prior to your becoming eligible to  contribute to
      the Thrift-Incentive Plan (TIP).

   .  The minimum amount for a rollover is $500.00.

   .  All rollover requests require completion of the TIP Rollover  Request Form
      (reverse side of these Guidelines) and supporting  documentation as shown
      on the form.
 
   .  The taxable portion of a total distribution from a  tax-qualified plan, or
      any portion of a Rollover IRA, is  eligible for rollover.

   .  Non-taxable funds, in-service withdrawals or Personal IRA  funds will not
      be accepted in TIP.

   .  Only checks can be accepted for rollover deposit. Stocks,  bonds, wire
      transfers and DTC transfers are not accepted.

   .  Forms, checks and supporting documentation are due at 5:00  p.m., five (5)
      business days prior to the end of the month to  the TIP Administrator,
      M-8, with fund investment occurring the  1st of the following month.

   .  You may access your rollover money in TIP through loans and  withdrawals.
      For more details, see The Sourcebook: A Guide To  Your Future Financial
      Security.

   .  TIP transactions are processed through the Benefits Express  phone system.
      A Caller Kit will be mailed to you.

PROCESSING DIRECT ROLLOVERS
   .  TIP accepts direct rollovers from other tax-qualified plans.  Checks
      should be made payable to:
         The Northern Trust Company - TIP
         50 South LaSalle Street, M-8
         Chicago, Illinois 60675

   .  The check must also reference your name, and your Social  Security number
      is your account number in TIP.

   .  You must provide a completed TIP Rollover Request Form and  the supporting
      documentation, even if the check is being  mailed directly to the TIP
      area.

PROCESSING IRA ROLLOVERS
   .  TIP accepts Rollover IRA funds, not Personal IRA funds. All  or part of
      the funds may be rolled over only if the IRA  consists solely of the
      taxable portion of the tax-qualified  distribution and its earnings. If
      any other contributions were  made to the IRA, no portion of the IRA is
      eligible for  rollover.

   .  To maintain rollover eligibility, the Internal Revenue  Service requires
      that qualified distributions be rolled over  into a qualified plan or
      Rollover IRA within 60 days of the  date of payment of your final
      distribution. If you are not  able to roll over into TIP within the 60 day
      timeframe, you  must deposit the funds into a Rollover IRA.

   .  Failure to deposit a tax-qualified distribution into another 
      tax-qualified plan or Rollover IRA within 60 days of payment  will
      disqualify the entire amount of your distribution from  any type of future
      rollover treatment. The funds would then be  ineligible for rollover into
      TIP.
 
             Any questions? Call (312) 444-4416 or (312) 444-7613.

                    AUGUST USHERS IN NEW TIP OPPORTUNITIES
                TAKE THE BENEFITS EXPRESS(TM) TO TIP INFORMATION
                     MAKE TIP CHANGES ANY MONTH YOU CHOOSE

On August 9, 1993, the Benefits Express(TM) Phone System will be introduced to
all TIP participants and the change to monthly processing of TIP information
will begin. What this means for you is that you'll be able to get information
about TIP and make changes to your TIP account just by picking up the phone.
And you'll be able to make those changes in any month you choose.

During the week of August 2, 1993, you'll receive  your Benefits Express Caller
Kit that will include a temporary PERSONAL IDENTIFICATION NUMBER (CALLED A
P.I.N.) to enter the system for the first time. When you make your first call,
you'll be prompted to select your own permanent P.I.N. It's a good idea to
select a number that's easy to remember. If you forget your P.I.N., you'll need
to request a new number and the replacement will take a few days. Your kit
will also include a CALLER'S CARD that outlines the steps for using Benefits
Express and summarizes the features and options of the system. In this memo
we'll preview Benefits Express and describe how the change to monthly
processing will make TIP more responsive and convenient than ever!

HELLO BENEFITS EXPRESS--'BYE 'BYE TIP CHANGE FORMS

The introduction of Benefits Express will eliminate the need to complete a
paper form to make a change to your TIP account in most (but not all) 
situations. For example:

WHEN YOU WANT TO....                                       THEN....

Increase or decrease your TIP contributions                Call Benefits Express

Request a loan                                             Call Benefits Express

FOR THE RECORD--BENEFITS EXPRESS CONFIRMS YOUR TRANSACTIONS--IN WRITING

Each time you complete a transaction through Benefits Express, you will receive
a confirmation (on paper) for your records, to document your request. A sample
confirmation sheet is included with this memo.

FOR YOUR INFORMATION--WHEN YOU'LL STILL NEED A PAPER FORM

Although Benefits Express is designed to streamline and automate most of your 
TIP transactions, there will still be times when you'll need to complete a 
paper form. For example:

WHEN YOU WANT TO....                         THEN....

Enroll in TIP for the first time             Complete an enrollment form

Change your TIP beneficiary                  Complete a beneficiary 
                                             designation form  

Request a financial hardship withdrawal      Complete the hardship withdrawal 
                                             documents

Roll over a distribution from the            
retirement plan of a former employer         Complete the rollover forms

Direct your distributions at retirement or   Complete the termination election
termination                                  forms

AND REMEMBER....

YOU CAN USE BENEFITS EXPRESS TO REQUEST ANY OF THE FORMS THAT ARE STILL 
NECESSARY.

NOTE: Forms for all transactions will continue to be available for any
      participant with a special need such as a hearing impairment or for
      anyone whose primary language is not English. Contact your TIP/ESOP
      representative to request a form.

NEED A TIP CHANGE? PICK A MONTH!

At the same time that Benefits Express is being introduced, TIP processing is 
switching from a quarterly to a monthly schedule.

What that means for you is that when you want to  make a change to your TIP
account, you get to pick the month that you want.

We've also increased the number of times you can request a specific 
transaction....from four times a year to six times a year. The chart below 
spells out your new opportunities.

Beginning January 1, 1994, regular withdrawals will 
have to satisfy a $1,000.00 minimum. The request 
will be checked against the withdrawal amount 
available at the time you make the call. Regular 
withdrawal requests for amounts less than $1,000.00 
can no longer be processed. THE MINIMUM WILL NOT 
APPLY TO HARDSHIP WITHDRAWAL REQUESTS.

NOTE: The rules for loans have not changed; you can still have up to two
      loans outstanding at any time. New loans can be requested in any month
      through Benefits Express.

DATES TO REMEMBER

The switch to a monthly processing schedule creates four key dates to keep in 
mind:

THE MONTHLY DEADLINE

This is the latest date that requests for TIP activity can be accepted during 
the month. It occurs five business days before the end of the month. In August,
for example, the monthly deadline will be on the 25th.

THE EFFECTIVE DATE

This is the date that all change requests are processed. It will occur on the 
first day of the month following the monthly deadline. Fund transfers, changes 
in contribution amounts or redirection of contributions will take place on this
date.

THE DISTRIBUTION DATE

This is the date when participants receive loan or withdrawal proceeds, or 
final distributions in the case of retirements and terminations. It will occur 
approximately five weeks after the effective date.

BENEFITS EXPRESS DATA UPDATE

This is the date on which all change information from the first of the month 
(the effective date) will be loaded into the Benefits Express phone system. 
Investment returns from the prior month are also updated at this time. The 
data update typically takes place on the 22nd of the month.

As a general rule, when you call Benefits Express you are hearing information 
from the data update that occurred in the prior month. That update will reflect 
account balances that are 4-7 weeks "old" depending on when you place your call.

In most months you will have an opportunity to base your transaction on the 
most current information available. This opportunity, which we call the "window 
period", occurs between the data update for the current month and the monthly 
deadline. It is generally "open" for 2-4 days. However, in certain months, the 
window may not be available. For example, the month of February is short and
contains a holiday. As a result, the data update may not take place until after 
the deadline for the month.

HERE'S AN EXAMPLE OF HOW THE MONTHLY PROCESSING SCHEDULE WORKS:
Joe requests a loan on September 20.
His loanable amount reflects the balances from the last data update on 
August 23.
The MONTHLY DEADLINE occurs on September 24.
The effect of the loan on Joe's account balances is loaded into Benefits 
Express on October 21, THE DATA UPDATE.
Joe receives the loan amount on November 8, THE DISTRIBUTION DATE.

Here's our example, and the months that precede and follow it in a chart form:

END-OF-QUARTER RESTRICTIONS ON BUYING AND SELLING NORTHERN TRUST COMMON STOCK 
TO CONTINUE

Northern Trust policy does not allow employees to buy or sell Northern Trust 
Common Stock during the period...beginning 10 business days prior to the end of 
each quarter...and ending two days after the release of public information 
regarding Northern Trust's earnings for the quarter. The policy also applies to
any TIP transactions--such as loans, withdrawals or transfers of funds-- --that 
involve the Northern Trust Common Stock Fund.

As a result, the TIP monthly processing deadline in the end-of-quarter months 
(March, June, September and December) will be earlier than in other months.

HERE'S A SUMMARY:

For TIP transactions that will not change your balance in the Northern Trust 
Common Stock Fund...the monthly deadline for any month of the year is the 
fifth business day before the end of the month...for example, September 24.

For TIP transactions in any month except March, June, September and December, 
the monthly processing deadline is five business days before the end of the 
month...for example, August 25.

FOR TIP TRANSACTIONS IN MARCH, JUNE, SEPTEMBER AND DECEMBER THAT WILL CHANGE 
YOUR BALANCE IN THE NORTHERN TRUST COMMON STOCK FUND, THE MONTHLY DEADLINE IS 
10 BUSINESS DAYS BEFORE THE END OF THE MONTH...FOR EXAMPLE, SEPTEMBER 17.

Failure to comply with the quarterly restrictions is considered a violation of 
company policy. 

HAVE A QUESTION?--YOUR TIP AND ESOP REPRESENTATIVES ARE STILL HERE TO HELP

Re: Your Contribution Rate Change

On September 14, 1993, you called Benefits Express to change your
Thrift-Incentive Plan contribution rate. This confirms that your change will 
be effective on October 1, 1993. As a result of your change, your rate of
contribution will be:

                5% Before-tax
                3% After-tax

IF YOU FEEL YOUR REQUEST WAS RECORDED IN ERROR CALL BENEFITS EXPRESS TO CHANGE
THIS REQUEST. IF YOUR FUND BALANCES APPEAR TO BE INCORRECT ON A FUTURE 
STATEMENT, IMMEDIATELEY CONTACT YOUR TIP/ESOP REPRESENTATIVE.

Thank you for calling Benefits Express

                           IMPORTANT INFORMATION ON
           TIP TRANSACTIONS INVOLVING THE NORTHERN TRUST STOCK FUND
 
It is the Northern Trust's policy to prohibit employees from buying or  selling
Northern Trust stock during the period from 10 business days prior  to the end
of each calendar quarter to two days after the public release of  quarterly
earnings information. This rule also applies to any TIP  transaction (transfers
of funds, loans, withdrawals) involving the Northern  Trust Common Stock Fund. 

                                                                              
                                                                              
     Therefore, the deadline for any TIP transactions involving the Northern
Trust Common Stock Fund is earlier at the end of a quarter than in other
months. 

       . For transactions that will not change your balance in the Northern
         Trust Common Stock Fund, the deadline for any month of the year is the
         5th business day before the end of the month.

       . For any months other than March, June, September, and December the
         deadline for all activity is the 5th business day before the end of
         the month. 

       . For any transaction involving the Northern Trust Common Stock Fund at
         the end of a calendar quarter, the deadline is the 10th business day
         prior to  the end of the month. In other words, any transaction that
         will change your  balance in the Northern Trust Common Stock Fund
         (transfers or funds, loans, withdrawals) that is requested after that
         date is a violation of company policy.

         Gentlemen:

               In connection with the registration pursuant to the provisions of
          the Securities Act of 1933, as amended, of an additional $10,000,000
          of participations in Fund D under The Northern Trust Company
          Thrift-Incentive Plan (the "Plan") consisting of shares of Common
          Stock of Northern Trust Corporation (the "Corporation"), we are of the
          following opinion:

               1.   Any and all shares of the Corporation which shall be
                    distributed to participants in the Plan will constitute
                    legally issued, fully paid and non- assessable shares of the
                    Corporation.

               2.   The Plan and The Northern Trust Company Thrift-Incentive
                    Plan Trust comply with all applicable provisions of the
                    Employee Retirement Income Security Act of 1974 (ERISA).

               We hereby consent to all references to our firm in the
          above-captioned Registration Statement and to the use of this opinion
          as an exhibit to the Registration Statement.

TO THE STOCKHOLDERS AND BOARD OF DIRECTORS,
NORTHERN TRUST CORPORATION


We have audited the accompanying consolidated statement of condition of
Northern Trust Corporation ( a Delaware Corporation) and subsidiaries as of
December 31, 1992 and 1991, and the related consolidated statements of income,
changes in stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1992.  These financial statements are the
responsibility of the Corporation's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.
     We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.
     In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Northern Trust
Corporation and subsidiaries as of December 31, 1992 and 1991, and the results
of their operations and their cash flows for the three years in the period
ended December 31, 1992 in conformity with generally accepted accounting
principles.
