                            THIRD AMENDMENT TO THE 
                          FIRST MIDWEST BANCORP, INC.
                     1989 OMNIBUS STOCK AND INCENTIVE PLAN
                     -------------------------------------

     The First Midwest Bancorp, Inc. 1989 Omnibus Stock and Incentive Plan is
hereby amended as follows:

     1.  Section 2.1(e) is amended to read:

          (e) "Committee" means the Compensation Committee of the Board of
Directors or such other committee appointed from time to time by the Board of
Directors to administer this Plan.  The Committee shall consist of two or more
members, each of whom shall qualify as a "non-employee director," as the term
(or similar or successor term) is defined by Rule 16b-3, and as an "outside
director" within the meaning of Code Section 162(m) and regulations thereunder.

     2.  Section 4.1 is amended to read:

          4.1  Administration.  The Committee shall be responsible for the
administration of the Plan.  The Committee, by majority action thereof (whether
taken during a meeting or by written consent), is authorized to interpret the
Plan, to prescribe, amend, and rescind rules and regulations relating to the
Plan, to provide for conditions and assurances deemed necessary or advisable to
protect the interests of the Company, and to make all other determinations
necessary or advisable for the administration of the Plan, but only to the
extent not contrary to the express provisions of the Plan.  Determinations,
interpretations, or other actions made or taken by the Committee pursuant to the
provisions of the Plan shall be final and binding and conclusive for all
purposes and upon all persons whomsoever.  To the extent deemed necessary or
advisable for purposes of Rule 16b-3 or otherwise, the Board may act as the
Committee hereunder.

     3.  Section 5.1 is amended to read:

          5.1  Number and Amount Available for Award to Single Participant.
Giving effect to the 5-for-4 stock split accomplished in the form of a stock
dividend paid during January 1997, the total number of shares of Stock subject
to Awards under the Plan may not exceed 2,096,875 (of this total number up to
100,000 shares of Stock may be issued in Restricted Stock), and the total number
of shares of Stock which may be made subject to Awards granted under the Plan in
any calendar year to any single Participant may not exceed 81,250.  Such numbers
of shares shall be subject to adjustment upon occurrence of any of the events
described in Section 5.3.  The shares to be delivered under the Plan may
consist, in whole or in part, of authorized but unissued Stock or treasury
Stock, not reserved for any other purpose.

 

     4.  Section 7.5 is amended to read:

          7.5  Payment.  Options shall be exercised by the delivery of a written
notice of exercise to the Company, setting forth the number of shares of Stock
with respect to which the Option is to be exercised, accompanied by full payment
for the Stock. The Option Price upon exercise of any Option shall be payable to
the Company in full either:

     (a)  in cash or its equivalent (including, for this purpose, the proceeds
          from a cashless exercise as permitted under Federal Reserve Board's
          Regulation T, or other borrowed funds),

     (b)  by tendering previously-acquired Stock having an aggregate Fair Market
          Value at the time of exercise equal to the total Option price
          (including, for this purpose, Stock deemed tendered by affirmation of
          ownership),

     (c)  by any other means which the Committee determines to be consistent
          with the Plan's purpose and applicable law, or

     (d)  by a combination of (a), (b), and (c).

The exercise of an Option shall cancel any related SAR to the extent of the
number of shares as to which the Option is exercised.  As soon as practicable
after receipt of each notice and full payment, the Company shall deliver to the
Participant a certificate or certificates representing acquired shares of Stock.

     5.   Section 7.10 is amended to read:

          7.10 Limited Transferability of Options.  Except as provided below, no
Option granted under the Plan may be sold, transferred, pledged, assigned, or
otherwise alienated or hypothecated, otherwise than by will or by the laws of
descent and distribution.  Further, all Options granted to a Participant under
the Plan shall be exercisable during his lifetime only by such Participant.
Notwithstanding the foregoing, the Committee may, in its discretion, authorize
all or a portion of the Options (other than Incentive Stock Options) granted to
a Participant to be on terms which permit transfer by such Participant to:

          (a) the spouse, children or grandchildren of the Participant
     ("Immediate Family Members");

          (b) a trust or trusts for the exclusive benefit of such Immediate
     Family Members, or;

          (c) a partnership in which such Immediate Family Members are the only
     partners,

                                       2

 

provided that:

          (i)  there may be no consideration for any such transfer;

          (ii) the Award Agreement pursuant to which such Options are granted
     expressly provides for transferability in a manner consistent with this
     Section 7.10; and

          (iii)  subsequent transfers of transferred Options shall be prohibited
     except those in accordance with Section 11. Following transfer, any such
     Options shall continue to be subject to the same terms and conditions as
     were applicable immediately prior to transfer, provided that for purposes
     of Section 11 hereof the term "Participant" shall be deemed to refer to the
     transferee.  The provisions of Sections 7 and 13 relating to the period of
     exercisability and expiration of the Option shall continue to be applied
     with respect to the original Participant, and the Options shall be
     exercisable by the transferee only to the extent, and for the periods, set
     forth in said Sections 7 and 13.

     6.   Section 8.9 is deleted and Sections 8.10, 8.11 and 8.12 are renumbered
8.9, 8.10 and 8.11, respectively.

     7.   Section 15 is amended in its entirety to read:

                                   Article 15

                                Tax Withholding

     15.1 Tax Withholding.  The Company shall have the power and the right to
deduct or withhold, or require a Participant to remit to the Company, an amount
sufficient to satisfy Federal, state, and local taxes, domestic or foreign,
required by law or regulation to be withheld with respect to any taxable event
arising as a result of the Plan.

     15.2 Share Withholding.  With respect to withholding required upon the
exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock,
or upon any other taxable event arising as a result of awards granted hereunder,
Participants may elect to satisfy the withholding requirement, in whole or in
part, by having the Company withhold shares of Stock having a Fair Market Value
on the date the tax is to be determined equal to the minimum statutory total tax
which would be imposed on the transaction. All such elections shall be
irrevocable, made in writing, signed by the Participant, and shall be subject to
any restrictions or limitations that the Committee, in its sole discretion,
deems appropriate.

                                       3

was duly adopted and approved by the Board of Directors of the Company on May
21, 1997 and shall become effective as of such date.

                            FOURTH AMENDMENT TO THE

                     1989 OMNIBUS STOCK AND INCENTIVE PLAN
                     -------------------------------------

     The First Midwest Bancorp, Inc. 1989 Omnibus Stock and Incentive Plan is
hereby amended as follows:

     1.   Section  13.2 is amended to read:

     13.2 Definition.  For purposes of the Plan, a "change in control"
shall mean any of the following events:

          (a)  Any "person" (as such term is used in Sections 13(d) and 14(d) of
               the Securities Exchange Act of 1934, as amended), other than (i)
               a trustee or other fiduciary holding securities under an employee
               benefit plan of the Company or a subsidiary, or (ii) a
               corporation owned directly or indirectly by the stockholders of
               the Company in substantially the same proportions as their
               ownership of stock of the Company, is or becomes the "beneficial
               owner" (as defined in Rule 13d-3 under said Act), directly or
               indirectly, of securities of the Company representing 10% or more
               of the total voting power of the then outstanding shares of
               capital stock of the Company entitled to vote generally in the
               election of directors (the "Voting Stock"), or

          (b)  During any period of two consecutive years, individuals, who at
               the beginning of such period constitute the Board of Directors of
               the Company, and any new director, whose election by the Board of
               Directors or nomination for election by the Company's
               stockholders was approved by a vote of at least two-thirds (2/3)
               of the directors then still in office who either were directors
               at the beginning of the period or whose election or nomination
               for election was previously so approved, cease for any reason to
               constitute a majority thereof, or

          (c)  The stockholders of the Company approve a merger of consolidation
               of the Company with any other corporation, other than a merger or
               consolidation which would result in the Voting Stock outstanding
               immediately prior thereto continuing to represent (either by
               remaining outstanding or by being converted into voting
               securities of the surviving entity) at least 80% of the total
               voting power represented by the Voting Stock or the voting
               securities of such surviving entity outstanding immediately after
               such merger or consolidation, or the stockholders of the Company
               approve a Plan of complete liquidation of the Company or an
               agreement for the sale or disposition by the Company of all or
               substantially all of the Company's assets.

 
The Board has final authority to determine the exact date on which a change in
control has been deemed to have occurred under (a), (b), and (c) above.

                            FIFTH AMENDMENT TO THE
                          FIRST MIDWEST BANCORP, INC.
                     1989 OMNIBUS STOCK AND INCENTIVE PLAN
                     -------------------------------------

     The First Midwest Bancorp, Inc. 1989 Omnibus Stock and Incentive Plan is
hereby amended as follows:

     1.   Section 7.5 is amended to read:

          7.5  Payment.  Options shall be exercised by the delivery of a written
notice of exercise to the Company, setting forth the number of shares of Stock
with respect to which the Option is to be exercised, accompanied by full payment
for the Stock. The Option Price upon exercise of any Option shall be payable to
the Company in full either:

          (a)  in cash or its equivalent (including, for this purpose, the
               proceeds from a cashless exercise as permitted under Federal
               Reserve Board's Regulation T, or other borrowed funds),

          (b)  by tendering previously-acquired Stock having an aggregate Fair
               Market Value at the time of exercise equal to the total Option
               price (including, for this purpose, Stock deemed tendered by
               affirmation of ownership),

          (c)  by any other means which the Committee determines to be
               consistent with the Plan's purpose and applicable law, or

          (d)  by a combination of (a), (b), and (c).

The exercise of an Option shall cancel any related SAR to the extent of the
number of shares as to which the Option is exercised.  As soon as practicable
after receipt of each notice and full payment, the Company shall deliver to the
Participant a certificate or certificates representing acquired shares of Stock.
Notwithstanding the foregoing, the Option price payable with respect to the
exercise of any Options by a Participant who has a deferral election in effect
under the Company's Nonqualified Stock Option - Gain Deferral Plan (the "Gain
Deferral Plan") shall be made solely be tendering previously-acquired Stock in
accordance with paragraph (b) above.  As soon as practicable after receipt of
notice of exercise and payment, the Company shall deliver to the trustee of the
trust established under the Gain Deferral Plan, a certificate or certificates
representing such number of shares of Stock determined by dividing (i) the
excess of (A) the Fair Market Value of the shares of Stock purchased pursuant to
such Option exercise, over (B) the aggregate exercise price of the shares of
Stock purchased, by (ii) the Fair Market Value of one share of Stock.  In
addition, as soon as practicable after receipt of such notice and payment of the
Option price (other than payment by affirmation of ownership), the Company shall
deliver to the Participant a certificate or certificates representing shares
with a Fair Market Value equal to the aggregate option exercise price paid, net
of any tax withholding pursuant to Section 15.2.  For purposes of the foregoing,
Fair Market Value shall be determined on the date of Option exercise.

 
     2.   Section 15 is amended in its entirety to read:

                                  Article 15

                                Tax Withholding

     15.1 Tax Withholding.  The Company shall have the power and the right to
deduct or withhold, or require a Participant to remit to the Company, an amount
sufficient to satisfy Federal, state, and local taxes, domestic or foreign,
required by law or regulation to be withheld with respect to any taxable event
arising as a result of the Plan.

     15.2 Share Withholding.  With respect to withholding required upon the
exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock,
or upon any other taxable event arising as a result of awards granted hereunder,
Participants may elect to satisfy the withholding requirement, in whole or in
part, by having the Company withhold shares of Stock having a Fair Market Value
on the date the tax is to be determined equal to the minimum statutory total tax
which would be imposed on the transaction; provided, however, that in the event
a deferral election is in effect with respect to the shares deliverable upon
exercise of an Option, then the Participant may only elect to have such
withholding made from the Stock tendered to exercise such Option.  All such
elections shall be irrevocable, made in writing, signed by the Participant, and
shall be subject to any restrictions or limitations that the Committee, in its
sole discretion, deems appropriate.


                                   * * * * *

     The foregoing Fifth Amendment to the 1989 Omnibus Stock and Incentive Plan
was duly adopted and approved by the Board of Directors of the Company on
November 19, 1997 and shall become effective as of such date.
