                NONQUALIFIED STOCK OPTION - GAIN DEFERRAL PLAN
                                 (As Restated)

     WHEREAS, First Midwest Bancorp, Inc. ("the Company') has heretofore
established the First Midwest Bancorp, Inc. 1989 Omnibus Stock and Incentive
Plan, as Amended (the "Stock Plan") for its Employees; and

     WHEREAS, the Company recognizes the unique qualifications of key employees
and the valuable services that they have provided; and

     WHEREAS, the Company desires to increase Company stock ownership by
facilitating the deferral of gains resulting from the exercise of Company
nonqualified stock Options;

     NOW, THEREFORE, the Company hereby restates the First Midwest Bancorp, Inc.
Nonqualified Stock Option - Gain Deferral Plan (the "Plan") as hereinafter
provided:

                                   ARTICLE 1
                                    GENERAL
                                    -------

     1.1  Effective Date.  The provisions of the Plan shall be effective as of
          --------------
December 1, 1997 (the "Effective Date").  The rights, if any, of any person
whose status as an Employee of the Company and its subsidiaries and affiliates,
if any, has terminated shall be determined pursuant to the Plan as in effect on
the date such Employee terminated, unless a subsequently adopted provision of
the Plan is made specifically applicable to such person.

     1.2  Purpose.  The purpose of the Plan is to increase Company stock
          -------
ownership by facilitating the deferral of gains resulting from the exercise of
Company nonqualified stock Options.

     1.3  Intent.  With respect to the participation of Employees hereunder, the
          ------
Plan is intended to be (and shall be construed and administered as) an "employee
pension benefit plan" under the provisions of the Employee Retirement Income
Security Act of 1974 ("ERISA") which is unfunded and maintained by the Company
or an Employer solely to provide retirement income to a select group of
management or highly compensated Employees as such group is described under
section 201(2), 301(a)(3), and 401(a)(1) of ERISA as interpreted by the U.S.
Department of Labor. The Plan is not intended to be a plan described in section
401(a) of the Code, or section 3(2)(A) of ERISA.  With respect to the
participation in the Plan by nonemployee directors of the Company, the Plan is
intended to be a plan of deferred compensation.  The obligation of the Company
and an Employer to make payments under this Plan constitutes nothing more than
an unsecured promise to make such payments and any property of the Company or an
Employer that may be set aside for the payment of benefits under the Plan shall
in the event of the Company's or Employer's bankruptcy or insolvency, remain
subject to the claims of the Company's general creditors and the Employer's
general creditors, respectively, until such benefits are distributed in
accordance with Article V herein.

                         ELIGIBILITY AND PARTICIPATION
                         -----------------------------

     3.1  Eligibility.  The Committee shall designate from time to time those
          -----------
Employees who shall participate in the Plan; provided, however, that such
                                             --------  -------

<PAGE>

of the later of the Effective Date or the date service as a nonemployee director
commences. The participation of any Participant may be suspended or terminated
by the Committee at any time, but no such suspension or termination shall
operate to reduce the balance of the Account of the Participant as of the

termination without such Participant's consent. An Employee or nonemployee
director shall cease to be a Participant when he terminates employment and
service as a director with the Company and all Employers and the balance in his
Account is distributed to him or on his behalf.

     3.3  Deferral Election Procedure.
          ---------------------------

               (i)  Each Participant may execute one or more Deferral Election
     Forms as set out in Appendix A.  Each Deferral Election Form shall be
     treated in accordance with Section 4.2.  In order to be effective with
     respect to the exercise of any Option or payment of any Stock Award, a
     Deferral Election Form must be executed by the Participant:  (i) in a
     calendar year preceding the exercise of such Options or vesting of the
     Stock Award; and (ii) at least six months prior to the exercise of such
     Options or vesting of the Stock Award; provided, however, that a Deferral
     Election Form executed by a Participant during the first 30 days following
     the later of the Effective Date of the Plan or the participation
     commencement date designated by the Committee pursuant to Section 3.2 for
     such Participant, shall be effective with respect to the exercise of
     Options or vesting of the Stock Award after the date of such Deferral
     Election Form without regard to clauses (i) and (ii).

               (ii) An Agreement shall be effective no earlier than the date on
     which it is delivered to the Administrator and shall continue in effect for
     all succeeding Plan Years unless otherwise superseded by a subsequent
     Deferral Election Form (or Deferral Revocation Form).

     3.4  Stock-for-Stock Payment Method for Options.  If a Participant has
          ------------------------------------------
executed a Deferral Election Form, and such Deferral Election Form is effective
under the terms of the Plan with respect to the Option being exercised, then the
Option price shall be payable to the Company in full solely by tendering shares
of Stock, which have been held for at least six months prior to the date of the
exercise of the Option, 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).  Shares of Stock tendered or
deemed tendered shall, for purposes of the six month holding rule, be deemed to
be newly-held following use to exercise the Option and thus cannot be used for a
subsequent exercise until six months have elapsed.

     3.5  Delivery of Stock.  As soon as practicable after (a) receipt of the
          -----------------
tendered Stock or the affirmation of ownership of Stock pursuant to Section 3.4
above, or (b) vesting of the Stock Award, the Company shall deliver to the
Trustee, as named pursuant to Article XI of the Plan, a certificate or
certificates representing the Profit Shares generated with respect to the
exercise of any such Option or vesting of the Stock Award.

                             PARTICIPANT ACCOUNTS
                             --------------------

     4.1  Accounts.  The Administrator shall establish and maintain, pursuant to
          --------
the terms of the Plan, one or more Accounts for each Participant consisting of
amounts credited to such Account pursuant to Section 4.2 below.  All amounts
which are credited to a Participant's Account shall be credited solely for
purposes of accounting and computation, and shall remain assets of the Company
subject to the claims of the Company's general creditors.  A Participant shall
not have any interest or right in or to such Account at any time.

     4.2  Participant Deferrals.  The Administrator shall credit to a
          ---------------------
Participant's Account for a Plan Year the amount of Profit Shares resulting from
the exercise of an Option or Options or vesting of Stock Awards for which a
valid Deferral Election Form is in effect.  In order for a Deferral Election
Form to be valid with respect to the exercise of an Option:  (a) the Deferral
Election Form must have been timely executed in accordance with Section 3.5; and
(b) with respect to an Option, (i) the exercise complies with all of the
applicable terms of the Option and of the Stock Plan; and (ii) the Option price
is satisfied by a tender of Stock as described in Section 3.4.

     4.3  Investment Procedure.  A Participant's Account shall be deemed
          --------------------
invested in Stock of the Company.  Any dividends deemed paid on Stock shall be
deemed to be reinvested in Stock. In the event of a change in the Stock of the
type that results in an adjustment to the Stock pursuant to adjustment
provisions set forth in the Stock Plan, then the Participant's Account shall be
deemed invested in Stock as so adjusted; provided, however, to the extent that
the adjustment results in a deemed investment in cash and stock, such cash shall
be deemed reinvested in Stock (as adjusted); provided, further, that if such
adjustment results in the deemed investment of the Account entirely in cash,
then such cash shall be deemed invested in an interest-bearing account and
credited with interest quarterly at an annual rate equal to the prime rate as
published in The Wall Street Journal at the beginning of such quarterly period
             -----------------------
plus 2%, or such other investments as the Committee may permit the Participants
to recommend to the trustee of the Trust established pursuant to Article XI
below.

     4.4  Valuation of Accounts.  The value of a Participant's Account shall be
          ---------------------
determined from time to time by the Administrator in the following manner:

               (i)  The income and expense, gains, and losses, both realized and
     unrealized, from such deemed investments as are required under Section 4.3
     shall be determined by the Administrator.  The amount so determined shall
     be allocated to the Account of a Participant proportionately in accordance
     with the procedures established by the Administrator.

               (ii) Each Participant's Account shall be valued as of the
     Valuation Date of each Plan Year or more frequently as determined in the
     sole discretion of the Administrator, and shall again be valued as of the
     date that a Participant receives a payment under the Plan, in accordance
     with the procedures established by the Administrator.

                                       5
<PAGE>

               (iii)  A Participant's Account shall be reduced by the amount of
     any benefits distributed to or on behalf of the Participant pursuant to
     Article V.

               (iv)   All allocations to and deductions from a Participant's
     Account under this Section 4.4 shall be deemed to have been made on the
     applicable Valuation Date in the order of priority set forth in this
     Section 4.4, even though actually determined at a later date.

                                   ARTICLE 5
                              PAYMENT OF BENEFITS
                              -------------------

     5.1  Entitlement to Benefit Payments.  Upon a Participant's separation from
          -------------------------------
service as an Employee or nonemployee director, as applicable, from the Company
and all Employers, the Participant shall be entitled to his Account Balance
payable by the Company or by his Employer at the time and in the manner
determined in accordance with Section 5.2.  Notwithstanding the foregoing, if a
Participant's separation from service is the result of termination "for cause,"
no benefits shall be payable to the Participant under the Plan and his Account
balance shall be zero.  A Participant shall be deemed to have been terminated
"for cause" if his employment or service as a director is terminated voluntarily
or involuntarily as a result of the Participant's fraud, misappropriation or
embezzlement of Company or Employer funds or property.  The Committee shall
determine whether a Participant's separation from service is "for cause."

     5.2  Commencement of Benefit Payments.  In connection with commencement of
          --------------------------------
participation in the Plan, a Participant shall elect on an election form to
receive payment of the Account Balance in a lump sum or in annual or quarterly
installments over a period of up to fifteen years.  The Participant may annually
change the election to an allowable alternative payout period by submitting a
new election form to the Committee, provided that any such election form is
submitted during a calendar year preceding and at least six months prior to the
Participant's separation from service and is accepted by the Committee in its
sole discretion; provided, however, that such advance filing period shall not
apply to an election form submitted prior to a Change in Control (as defined in
the Stock Plan) which is applicable to a separation from service which occurs on
or after the date of such Change in Control.  The election form most recently
accepted by the Committee shall govern the payout of the Account Balance.  If a
Participant does not make any election with respect to the payment of the
Participant's Account Balance, then such benefit shall be payable in five annual
installments. The lump sum payment shall be made, or installment payments shall
commence, no later than 30 days after the last day of the calendar quarter in
which the Participant experiences the separation from service; provided,
however, the Participant may elect to have the payment commencement date delayed
for up to five (5) years from the separation date by submitting an election form
to that effect which is accepted by the Committee at least six months prior to
the separation date; provided, further, if the Participant's Account Balance is
less than $25,000 at the time of separation from service, payment of the Account
Balance will be made in a lump sum no later than 30 days after the last day of
the calendar quarter in which the separation from service occurs.
Notwithstanding the foregoing, the Committee, in its sole discretion, shall
establish the commencement date for the payment of benefits, the deductibility
of which may be limited by Code Section 162(m), as the earliest practicable date
upon which such limitations would not apply.

                                       6
<PAGE>

     5.3  Short-Term Payout.  In connection with a Deferral Election, a
          -----------------
Participant may irrevocably elect to receive a future "Short-Term Payout" from
the Plan with respect to the amounts covered by such Deferral Election.  The
Short-Term Payout shall be a lump sum payment in an amount that is equal to the
Profit Shares covered by the particular Deferral Election plus additional shares
credited in the manner provided in Section 4.2 above on that amount, determined
at the time that the Short-Term Payout becomes payable.  Subject to the other
terms and conditions of this Plan, each Short-Term Payout elected shall be paid
out during a 60 day period commencing immediately after the last day of any Plan
year designed by the Participant that is at least three Plan Years after the
Plan Year in which the Profit Shares were actually deferred.  Notwithstanding
the foregoing, the Committee, in its sole discretion may delay the payment of
any Short-Term Payment, the deductibility of which may be limited by Code
Section 162(m), to this earliest practicable date upon which such limitations
would not apply.

     5.4  Unforeseeable Financial Emergencies.  If the Participant experiences
          -----------------------------------
an Unforeseeable Financial Emergency, the Participant may petition the Committee
to (i) suspend any Deferral Election made by a Participant and/or (ii) receive a
partial or full payout of the Participant's Account Balance from the Plan.  The
payout shall not exceed the lesser of the Participant's Account Balance, or the
amount reasonably needed to satisfy the Unforeseeable Financial Emergency.  If,
subject to the sole discretion of the Committee, the petition for a suspension
and/or payout is approved, suspension shall take effect upon the date of
approval and any payout shall be made within 60 days of the date of approval.
For purposes of this Section 5.4, "Unforeseeable Financial Emergency" shall mean
an unanticipated emergency that is caused by an event beyond the control of the
Participant that would result in severe financial hardship to the Participant
resulting from (i) a sudden and unexpected illness or accident of the
Participant or a dependent of the Participant, (ii) a loss of the Participant's
property due to casualty, or (iii) such other extraordinary and unforeseeable
circumstances arising as a result of events beyond the control of the
Participant in which distribution is necessary to preserve the value of the
benefits of this Plan to the Participant, all as determined in the sole
discretion of the Committee.

     5.5  Withdrawal Election.  A Participant (or, after a Participant's death,
          -------------------
his or her Beneficiary) may elect, at any time, to withdraw all of his or her
Account Balance, less a withdrawal penalty equal to 10% of such amount (the net
amount shall be referred to as the "Withdrawal Amount").  This election can be
made at any time, before or after death or separation from service and whether
or not the Participant (or Beneficiary) is in the process of being paid pursuant
to an installment payment schedule.  No partial withdrawals of the Withdrawal
Amount shall be allowed. The Participant (or his or her Beneficiary) shall make
this election by giving the Committee advance written notice of the election in
a form determined from time to time by the Committee.  The Participant (or his
or her Beneficiary) shall be paid the Withdrawal Amount within 60 days of his or
her election.  Once the Withdrawal Amount is paid, the Participant's right to
voluntarily submit Deferral Elections under the Plan shall terminate and the
Participant shall not be eligible to make any Deferral Election for the
remainder of the Plan Year of the Withdrawal Election and the next Plan Year.
Notwithstanding the foregoing, the Committee, in its sole discretion may delay
the payment of any Withdrawal Amount, the deductibility of which may be limited
by Code Section 162(m), to this earliest practicable date upon which such
limitations would not apply.

     5.6  Payments in Stock.  Unless a Participant's Account Balance has been
          -----------------
deemed invested in cash pursuant to an adjustment described in Section 4.2
above, all payments with respect to such Account Balance shall be made in shares
of Stock (as such Stock may be adjusted in accordance with Section 4.2).

     6.1  Commencement of Payments After Death.  If a Participant dies before
          ------------------------------------
receiving his entire Account Balance, the remainder of the Account otherwise
payable with respect to the Participant shall be paid to the Participant's
beneficiary or beneficiaries as a single lump-sum amount within ninety (90) days
following the date on which the Administrator is notified of the Participant's
death.

     6.2  Designation of Beneficiary.  A Participant may, by executing a
          --------------------------
Beneficiary Designation Form (see Appendix A) during the Participant's lifetime,
designate one or more primary and contingent beneficiaries to receive his
Account balance which may be payable to the Participant hereunder following the
Participant's death, and may designate the proportions in which such
beneficiaries are to receive such payments.  A Participant may change such
designations from time to time, and the last written designation filed with the
Administrator prior to the Participant's death shall control.  If a Participant
fails to specifically designate a beneficiary or, if no designated beneficiary
survives the Participant, payment shall be made by the Administrator in the
following order of priority:

               (i)   to the Participant's surviving spouse; or if none,

               (ii)  to the Participant's children, per stirpes; or if none,
                                                    --- -------

                                   ARTICLE 9
                           MISCELLANEOUS PROVISIONS
                           ------------------------

     9.1  Amendment.  The Company reserves the right to amend the Plan in any
          ---------
manner that it deems advisable by a resolution of the Board or the Committee.
No amendment shall, without the Participant's written consent, affect the amount
of the Participant's Account balance at the time the amendment becomes effective
or the right of the Participant to receive a distribution of his Account
balance.  Notwithstanding the foregoing, following a Change in Control (as
defined in the Stock Plan), no amendment or termination of the Plan shall,
without the Participant's written consent, have an adverse effect on the
computation or amount or entitlement to benefits of such Participant, including,
but not limited to the time or manner of the payment of the Account.  For
purposes hereof, an "adverse effect" shall include, but not be limited to, any
acceleration of the payment of the Account.

     9.2  Termination.  The Company reserves the right to terminate the Plan at
          -----------
any time.  No termination shall, without the Participant's written consent,
affect the amount of the Participant's Account balance prior to the termination
or the right of the Participant to receive a distribution of his Account
balance.

     9.3  No Assignment.  The Participant shall not have the power to pledge,
          -------------
transfer, assign, anticipate, mortgage or otherwise encumber or dispose of in
advance any interest in amounts payable hereunder or any of the payments
provided for herein, nor shall any interest in amounts payable

                                      10
<PAGE>

hereunder or in any payments be subject to seizure for payments of any debts,
judgments, alimony or separate maintenance, or be reached or transferred by
operation of law in the event of bankruptcy, insolvency or otherwise.

     9.4  Incapacity.  If any person to whom a benefit is payable under the Plan
          ----------
is an infant or if the Administrator determines that any person to whom such
benefit is payable is incompetent by reason of physical or mental disability,
the Administrator may cause the payments becoming due to such person to be made
to another for his benefit.  Payments made pursuant to this Section shall, as to
such payment, operate as a complete discharge of the Plan, the Company, each
Employer, the Committee and the Administrator.

     9.5  Successors and Assigns.  The provisions of the Plan are binding upon
          ----------------------
and inure to the benefit of the Company, each Employer, its respective

          -------------
accordance with the laws of Illinois to the extent not pre-empted by the
provisions of ERISA.

          --------------------------
construed as a contract of employment or deemed to give any Participant the
right to be retained in the employ of any Employer or any equity or other
interest in the assets, business or affairs of any Employer. No Participant
hereunder shall have a security interest in the assets of any Employer used to
make contributions or pay benefits.

     9.8  Severability.  If any provision of the Plan shall be held illegal or
          ------------
invalid for any reason, such illegality or invalidity shall not affect the
remaining provisions of the Plan, but the Plan shall be construed and enforced
as if such illegal or invalid provision had never been included herein.

     9.9  Notification of Addresses.  Each Participant and each beneficiary
          -------------------------
shall file with the Administrator, from time to time, in writing, the post
office address of the Participant, the post office address of each beneficiary,
and each change of post office address.  Any communication, statement or notice
addressed to the last post office address filed with the Administrator (or if no
such address was filed with the Administrator, then to the last post office
address of the Participant or beneficiary as shown on the Company's or
Employer's records) shall be binding on the Participant and each beneficiary for
all purposes of the Plan and neither the Administrator nor the Company or an
Employer shall be obligated to search for or ascertain the whereabouts of any
Participant or beneficiary.

          --------------
adopting Employer shall be deemed to have authorized the Committee and the
Administrator (if different from the Committee) to act for it in all matters
arising under or with respect to the Plan and shall comply with such other terms
and conditions as may be imposed by the Administrator.

     10.3 Company as Agent.  Each adopting Employer hereby irrevocably grants
          ----------------
the Company full and exclusive power to exercise, enforce or waive any right
which such Employer might otherwise have under the terms of the Plan, and each
adopting Employer irrevocably appoints the Company as its agent for such
purpose.

     10.4 Termination.  If authorized by the Company, each adopting Employer
          -----------
may, upon written notice to the Company, cease to participate in the Plan with
respect to its Employees by resolution of its governing body.

                                     -----

     11.1 Trust.  A Trust has been established under the Plan by the execution
          -----
of a separate trust agreement entitled the First Midwest Bancorp, Inc.
Nonqualified Stock Option - Gain Deferral Trust with one or more trustees.  The
Trust is intended to be maintained as a "grantor trust", under section 677 of
the Code, for which the Company is the grantor.  The assets of the Trust will be
held, invested and disposed of by the trustee, in accordance with the terms of
the Trust, for the exclusive purpose of providing Plan benefits for the
Participants.  Notwithstanding any provision of the Plan or the Trust to the
contrary, the assets of each Trust shall at all times be subject to the claims
of the grantor's general creditors in the event of the grantor's insolvency or
bankruptcy.

     11.2 Contributions and Expense.  The Company, in its sole discretion, and
          -------------------------
from time to time, may make contributions to the Trust.  All benefits under the
Plan and expenses chargeable to the Plan, to the extent not paid directly by the
Company, shall be paid from the Trust.

     11.3 Trustee Duties.  The powers, duties and responsibilities of the
          --------------
trustee shall be as set forth in the Trust agreement and nothing contained in
the Plan, either expressly or by implication, shall impose any additional powers
or duties responsibilities upon the trustee.

     11.4 Voting Rights.  Each Participant (or, in the event of his death, his
          -------------
beneficiary) shall have the right to direct the Trustee as to the manner in
which whole and partial shares of Stock allocated to his Account as of the
record date are to be voted on each matter brought before an annual or special
stockholders' meeting.  Upon timely receipt of such directions, the Trustee
shall on each such matter vote as directed the number of shares (including
fractional shares) of Stock allocated to such Participant's Account, and the
Trustee shall have no discretion in such matter.  The directions received by the
Trustee from Participants shall be held by the Trustee in confidence and shall
not be divulged or released to any person, including officers or employees of
any Employer.  The Trustee shall vote allocated shares for which it has not
received direction in the same proportion as directed shares are voted, and
shall have no discretion in such matter.  Additionally, in the event a tender

                                       12
<PAGE>

offer is extended with respect to the Stock, each Participant shall have the
identical rights to direct the voting of the shares allocated to his Account as
detailed in the preceding sentences of this Section 11.4.

     11.5 Reversion to the Company.  The Company shall not have any beneficial
          ------------------------
interest in the Trust and no part of the Trust shall ever revert or be repaid to
the Company prior to the payment of all Plan benefits to Participants, except
with respect to amounts allocable to forfeited benefits (including without
limitation, any amounts forfeited on account of a termination "for cause") and
as otherwise reasonably determined by the Committee not to be necessary to pay
benefits to Participants.

                              Summary Description
                                January 1, 2000

INTRODUCTION
------------

The purpose of this Summary Description is to provide general information about
the Nonqualified Stock Option Gain Deferral Plan (the "Gain Deferral Plan").  A
complete copy of the Gain Deferral Plan, as well as additional information about
First Midwest and the Common Stock issuable thereunder, is available upon
request.

The Gain Deferral Plan provides that the Compensation Committee (the
"Committee") of the Board of Directors of First Midwest Bancorp, Inc. ("First
Midwest" or the "Company") is responsible for the administration of the Gain
Deferral Plan.  The Committee is authorized to interpret the Gain Deferral Plan,
to prescribe and modify  its rules and procedures, and to make all other
determinations necessary in its administration.

PURPOSE OF THE GAIN DEFERRAL PLAN
---------------------------------

The purpose of the Gain Deferral Plan is to further stock ownership of certain
key executives and directors of First Midwest by facilitating deferral of gains
resulting from the exercise of First Midwest Nonqualified Stock Options
("options").

The Gain Deferral Plan permits the deferral of gains realized as a result of the
exercise of options granted pursuant to the First Midwest Bancorp, Inc.  1989
Omnibus Stock and Incentive Plan, as Amended (the "1989 Plan") and the Non-
Employee Directors' 1997 Stock Option Plan ("Directors' Plan").  In order to
defer receipt of gains resulting from such exercises, participants must make
appropriate elections and must exercise their options only through the exchange
of First Midwest Common Stock held for six months or more prior to the exercise
date.  Deferred gains can only be invested in First Midwest Common Stock;
dividends earned on such Common Stock purchased with deferred gains can likewise
only be reinvested.

ELIGIBILITY FOR PARTICIPATION
-----------------------------

The Gain Deferral Plan is structured as a "Nonqualified Plan" under applicable
IRS and Department of Labor ("DOL") guidelines.  As such, eligibility for
participation by employees must be monitored closely to ensure that the Gain
Deferral Plan maintains compliance with these rules, regulations and limitations
and is not disqualified.  Accordingly, eligibility for participation in the Gain
Deferral Plan will be determined by the Committee based upon the compensation
guidelines of the IRS and DOL.

Additionally, the ability to defer gains from option exercises is further
restricted to participants who own 500 or more shares of First Midwest Common
Stock  in their own name, in joint tenancy with their spouse or in an
alternative ownership form whereby the participant has sole voting and
investment power (such as a Trust).

ELECTION TO PARTICIPATE
-----------------------

In order to begin participation in the Gain Deferral Plan, a participant must
execute a Deferral Election Form.  A participant may execute such form within 30
days following the participant's commencement date as determined by the
Committee.  The deferral election will apply to all options exercised under the
1989 Plan and the Directors' Plan where First Midwest Common Stock is used as
the sole payment of the exercise price.  If a participant does not execute a
form within 30 days following the effective date of his/her participation, the
deferral election will become effective only for options exercised in the
calendar year following, and at least six months after, the execution date of
the form.  For example, if a participant (who did not execute a form in the 30
day period described above) executes a form on November 1, 1999, then May 1,
2000 is the first date on which gains can be deferred from the exercise of
options under the Gain Deferral Plan.

A participant may execute additional forms, or a Deferral Election Revocation
Form, with each subsequent form superseding all prior forms in accordance with
the timing provisions contained in the Gain Deferral Plan.

                                       1
<PAGE>

If a participant executes a Deferral Election Form, it will apply to all option
exercises that utilize First Midwest Common Stock as consideration until
revoked.  However, the participant may still exercise options using cash as
consideration (or in cashless exercises) to the maximum extent allowed by the
1989 Plan or the Directors' Plan.

The Deferral Election Form and the Deferral Election Revocation Form are
attached to this Summary Description as Exhibit A and B, respectively.

PAYMENT OF THE OPTION EXERCISE PRICE
------------------------------------

Under the Gain Deferral Plan, the option exercise price will be payable in full
to First Midwest solely by tendering shares of First Midwest Common Stock which
have been held for at least six months or more prior to the date of the option
exercise.  Such shares must be registered only in the name of the participant,
in joint tenancy with the participant's spouse or in an alternative ownership
form wherein the participant maintains sole voting and investment power (such as
a Trust).  Shares tendered will be considered as newly held for purposes of the
six month holding rule and may not be used for a subsequent option exercise for
at least six months.

The participant must use the Notice of Intention to Exercise Nonqualified Stock
Options With Gain Deferral, which is attached to this Summary Description as
Exhibit C.

INVESTMENT OF DEFERRED GAINS
----------------------------

Upon the exercise of options under the Gain Deferral Plan, the participant will
be required to pay, in cash,  FICA and Medicare taxes at the time of exercise.
                    --------
However, participants who are Directors will not be required to make such
payment because no such taxes are due on Director compensation.   No Federal or
State income tax withholding will be required at the time of exercise.  After
such taxes are paid, First Midwest will deposit certificates of First Midwest
Common Stock representing the gain realized from the exercise in a Grantor Trust
(as further described below).  Each participant's shares will be maintained in
an individual account.  All dividends received on such shares will be reinvested
in additional shares of First Midwest Common Stock.

MAINTENANCE OF PARTICIPANT ACCOUNT BALANCES
-------------------------------------------

Since the Gain Deferral Plan is not an ERISA-Qualified Plan, it does not carry
the same protections under ERISA as do such plans.

Nonetheless, in order to facilitate the administration of  participant balances,
First Midwest has established a Grantor Trust through a third party  trustee
(not First Midwest).  Although the Gain Deferral Plan participants will continue
to be unsecured creditors of First Midwest under the Grantor Trust (as is
required by Internal Revenue Code rules to preserve the non taxability of funds
to the participants until distribution) the Trust provides a vehicle for the
direct distribution of participant balances by the Trustee when such amounts
become payable.

DISTRIBUTIONS FROM THE GAIN DEFERRAL PLAN
-----------------------------------------

Distributions of account balances under the Gain Deferral Plan are payable upon
termination, disability, retirement or death (a "distribution event").  The
definition of disability for the Gain Deferral Plan will be the same as the
definition of disability in the Group Long Term Disability Plan.

All Plan account balances due to be distributed with a value of $25,000 or less
will be distributed on the first distribution date.  Distributions with a value
in excess of $25,000 will be distributed in accordance with the participant's
election. The first distribution will be made in the first 30 days of the
calender quarter following the distribution event.

Due to certain accounting restrictions placed on the Gain Deferral Plan, all
distributions from the Gain Deferral Plan will be made in the form of First
Midwest's stock and will not be made in cash.

A participant will be asked to make a distribution election upon admittance to
the Gain Deferral Plan.  Distributions are currently allowed in a lump-sum (in
the form of First Midwest Common Stock) or in annual or quarterly installments
(of First Midwest Common Stock) of up to 15 years.  Additionally, a participant
can elect to defer the receipt of distributions from the Gain Deferral Plan
(whether such distributions are in a lump-sum or in installments)

                                       2
<PAGE>

for up to 5 years. For example, a participant may elect to receive his/her
first annual or quarterly distribution under the Gain Deferral Plan for 3 years
from the date of retirement or termination. After the 3 year period has expired,
annual or quarterly distributions will begin within 30 days after the end of the
quarter that is three years from the date of the distribution event.

A distribution can be changed, but only for a distribution event which occurs
both during the calendar year following the year in which the election is
----
changed, and 6 months prior to the distribution event.   For example, if a
         ---
participant originally elects a distribution of 5 annual installments and on
November 1, 1999 changes that election to 10 annual installments, the change in
distribution election to 10 years would only be applicable for distribution
events after May 1, 2000 (the calendar year following, and 6 months after, the
date on which the change was made). These waiting periods will not apply to a
change which is made prior to a change-in-control of First Midwest as defined in
the 1989 Plan, and which is applicable to a distribution event which occurs on
or after a change-in-control. However, this exception is subject to approval by
the Committee of First Midwest Bancorp, Inc. as further discussed in the Plan
Document.

If, for any reason, a participant does not elect a form of distribution, the
default option for distributions to that participant will be 5 annual
installments.

To provide maximum flexibility, the Gain Deferral Plan also permits certain
short-term payouts and a withdrawal election.  The short-term payouts provide
participants with access to all or a portion of a specifically identified stock
                                                  -----------------------------
option gain deferral amount, plus dividends, payable to the participant in 3
---------------------------
years or more after the end of the gain deferral plan year in which the short-
term payout election is made.  Short-term payouts are only made in lump-sums.
The withdrawal election feature permits a participant to withdraw his/her entire
account balance at any time (during employment with First Midwest or after
termination of employment), less a 10% withdrawal penalty and forfeiture of
participation in the Gain Deferral Plan for one full plan year (if still
employed or serving as a Director of First Midwest).

The Election of Form of Distribution Form and the Request for Change in Election
of Form of Distribution Form are attached to this Summary Description as Exhibit
D (2 pages).

TAXABILITY OF DEFERRED GAINS AND DISTRIBUTIONS
----------------------------------------------

Since director compensation is not subject to FICA and Medicare taxes, no FICA
or Medicare tax will be applied to deferred gain upon the exercise of Directors'
Plan options.  Distributions to directors from the Gain Deferral Plan are taxed
as ordinary income in the year received as Form 1099 income based upon the
distribution election selected by the recipient.  Furthermore, since Federal and
State income tax withholding does not apply to director compensation, no such
withholding tax will be deducted by First Midwest.  Directors' should consult
their tax advisors for guidance regarding estimated income tax payments that may
be advisable after receiving gain deferral plan distributions.

FICA tax will be applied to deferred gains upon the exercise of 1989 Plan stock
options by employees up to the maximum FICA limit for each year.  Once a
participant reaches the maximum FICA limit for the year (based upon total
compensation for that year, not just deferred gains) no further FICA taxes will
be due.  Medicare tax will be applied to all deferred gains at the time of
exercise on an unlimited basis as required by law.  No Federal or State income
tax withholding will be assessed to the gain at the time of exercise.  Due to
IRS restrictions, FICA and Medicare taxes must be paid in cash.

Distributions from the Gain Deferral Plan are taxed to non-Director participants
in the year received as W-2 income based upon the distribution election selected
by the participant.  At the time of distribution, all such amounts will be
subject to Federal and State income tax withholding, but not to FICA or Medicare
tax.

All distributions from the Gain Deferral Plan are taxed as ordinary income equal
to the value of the stock at the time it is distributed.  Such value will be the
recipient's tax basis in the stock for purposes of computing taxable gain or
loss when the stock is subsequently sold.

VOTING RIGHTS
-------------

Each participant in the Gain Deferral Plan will have the right to instruct the
Trustee of the Grantor Trust as to the manner in which all shares of Common
Stock allocated to such participant's account shall be voted on each matter
brought before an annual or special stockholders' meeting.  The Trustee shall
have no discretion in determining the manner of voting such shares.
Additionally, in the event of a tender offer, each participant shall have the
right to direct the Trustee to tender or not to tender shares of Common Stock
allocated to such participant's account.

                                       3

RISKS OF PARTICIPATION
----------------------

Participants should be aware that certain risks are associated with
participation in the Gain Deferral Plan.  Some of these risks are greater than
the risks associated with participation in an other First Midwest benefit and
retirement plans.

Because the Gain Deferral Plan is a Nonqualified Plan, the participant will be
an unsecured creditor of First Midwest with respect to all amounts comprising
such participant's account balance.  As an unsecured general creditor, the
participant's benefits are at risk in the unlikely event that First Midwest
becomes insolvent or is declared bankrupt.

Although the participants may realize substantial current tax benefits from the
deferral of gains from the exercise of options, the ultimate distribution of
such gains will represent ordinary income and may be taxed at rates higher than
long-term capital gain rates.  The participant should consider, when deciding
to participate in the Gain Deferral Plan, whether to exercise options on a
taxable basis and hold the underlying Common Stock to take advantage of long-
term capital gain tax rates.

The Gain Deferral Plan may only hold First Midwest Common Stock as an investment
under current accounting rules. Accordingly, each participant should consider
whether the investment represented by his/her account balance in the Gain
Deferral Plan, together with such participant's other investments in First
Midwest Common Stock, represents an appropriate allocation of the participant's
total assets.

OTHER INFORMATION
-----------------

1.   Unsecured General Creditor - Each participant is an unsecured creditor of
     --------------------------
     First Midwest with respect to such participant's account balances.  The
     unsecured status is necessary to protect the account balances from being
     taxed currently.

2.   Plan Documents Governs the Gain Deferral Plan - This Summary Description
     ---------------------------------------------
     has been prepared to provide a better understanding of the benefits and
     features of the Gain Deferral Plan.  The participant's benefits and rights
     under the Gain Deferral Plan are at all times governed by the text of the
     First Midwest Bancorp, Inc. Nonqualified Stock Option Gain Deferral Plan
     document.  Such document is in no way altered or modified by the contents
     of this Summary Description.

3.   Amendment or Termination of the Gain Deferral Plan; Effect of Change-in-
     -----------------------------------------------------------------------
     Control - First Midwest reserves the right to amend or terminate the Gain
     -------
     Deferral Plan, in whole or in part, at any time its sole discretion.  No
     amendment or termination of the Gain Deferral Plan can eliminate benefits
     accrued to the date of such amendment or termination.  Following a change-
     in-control, amendments or termination which would adversely affect the
     amount of, or entitlement to, benefits of a participant or beneficiary may
     not be made unless the participant or beneficiary consents in writing.

4.   Not an Employment Contract - The Gain Deferral Plan does not constitute a
     --------------------------
     contract of employment between the participants and First Midwest.

5.   Plan Administration - Discretion with respect to the determination of
     -------------------
     benefits under the Gain Deferral Plan will be reserved to the Committee.
     Day to day administration will be delegated to the First Midwest Retirement
     and Benefit Plan Administration Committee.

6.   Consult Your Financial and Tax Advisor - Although the Gain Deferral Plan is
     --------------------------------------
     intended to enable participants to obtain the benefits of a tax deferred
     account and earnings credited thereto, no assurance can be given as to the
     actual after-tax benefit that may be achieved.  Accordingly, each
     participant should consult a personal tax and financial advisor for
     detailed information and guidance regarding participation in the Gain
     Deferral Plan.

AVAILABLE INFORMATION
---------------------

The Company has filed a Registration Statement with the Securities and Exchange
Commission (the "SEC") pursuant to the Securities Act of 1933 (the "Securities
Act") with respect to the shares of Common Stock which may be issued under the
1989 Plan and Directors' Plan and deferred under the Gain Deferral Plan.
Pursuant to the rules of the SEC, this Summary Description does not contain all
of the information set forth in the Registration Statement and exhibits thereto,

RESALE OF SHARES
----------------

None of the 1989 Plan, the Directors' Plan or the Gain Deferral Plan (the
"Plans") apply any specific restrictions on the resale of shares of Common Stock
issued to recipients under the Gain Deferral Plan.  However, the Securities Act
and Exchange Act may impose certain limitations on such resale.

Under the Securities Act, all directors and certain policy-making executive
officers of the Company and certain of its subsidiaries may be deemed to be
"affiliates" of the Company for purposes of the Securities Act. Because such
affiliates are so closely identified with the Company, sales of Common Stock by
such persons may be deemed to be sales of Common Stock by the Company. Rule 144,
promulgated under the Securities Act, sets forth a "safe harbor" procedures for
affiliates to sell shares yet not have the sale be deemed a distribution of
Common Stock on behalf of the Company. Rule 144 restricts the number of shares
of Common Stock which may be sold by an affiliate during any 90-day period,
designates a manner of sale and requires the filing of a notice of proposed sale
with the SEC. Executive officers of the Company who are considered "affiliates"
of the Company for purposes of the Securities Act include the Chairman,
President and any Executive Vice President of the Company. Any affiliates of the
Company should consult with a qualified legal advisor regarding his or her own
situation before making any resales of Common Stock issued pursuant to the Plan.

Section 16(b) of the Exchange Act provides that, in certain circumstances, the
profit realized by an affiliate of the Company on the purchase and sale, or sale
and purchase, of Common Stock within a six-month time frame, is recoverable by
the Company from the affiliate if it is a prohibited "short-swing profit".
Accordingly, employees of the Company or its subsidiaries who are considered
affiliates (as described in the preceding paragraph) should review the
implications of the "short-swing profit" prohibitions prior to exercising any
options or prior to disposing of any shares of Common Stock purchased or
otherwise received under the Plans. General information about the applicability
of Section 16(b) and the rules promulgated thereunder to the options granted
under the 1989 Plan and Directors' Plan is included in the applicable Appendix
or Summary Description describing such awards.

                            DEFERRAL ELECTION FORM
                            ----------------------

To:  Office of the Corporate Controller of First Midwest Bancorp, Inc:

This Deferral Election Form sets forth my election to defer, as specified below,
the Profit Shares (defined below) receivable upon stock Option exercises using
the stock-for-stock method of payment under the First Midwest Bancorp, Inc.
Nonqualified Stock Option Gain Deferral Plan (the "Gain Deferral Plan"), subject
to the terms, definition of terms, and conditions of the Gain Deferral Plan
which are incorporated herein by reference.

I understand that, in order to be effective with respect to the exercise of any
Option, this Deferral Election Form must be executed in a calendar year
preceding, and at least six months prior to, the exercise of such Options,
except that if this Deferral Election Form is executed within 30 days following
the inception of the Gain Deferral Plan or, if later, the date I was first
designated as eligible to participate in the Gain Deferral Plan, then this
Deferral Election Form will be effective for all Options exercised after the
date on which this Deferral Election Form is executed. Furthermore, I understand
that this Form supersedes, as of its earliest effective date under the preceding
sentence, the Deferral Election Form that I have previously executed, if any.

I understand that this Deferral Election Form shall be effective for all
subsequent calendar years, until the earlier of: (i) the first day of the
calendar year following the year in which I execute a Deferral Election
Revocation Form; or (ii) the date any subsequently executed Deferral Election
Form becomes effective.

The Profit Shares, as made eligible for deferral under the terms of the Gain
Deferral Plan, and effectively deferred under this Deferral Election Form, shall
be the number of shares equal in value to the excess of (1) the Fair Market
Value of the shares of Stock purchased on Option exercise, over (2) the exercise
price of the shares of Stock purchased, divided by the Fair Market Value of one
share of Stock. For the purposes of this election, Fair Market Value shall be
determined as the average of the high and low market prices of First Midwest
Bancorp, Inc. common stock as quoted on the NASDAQ National Market System on the
date of Option exercise or on the following date, if no shares are traded on the
exercise date.

Therefore, based on the foregoing, I elect to defer, for all Options exercised
consistent with the timing rules and Option price tender methods described
above, the Profit Shares.

PART ONE
--------

To:  Office of the Corporate Controller of First Midwest Bancorp, Inc:

In accordance with the First Midwest Bancorp, Inc. 1989 Omnibus Stock and
Incentive Plan, as Amended (the "1989 Plan"), the Non-Employee Directors' 1997
Stock Option Plan (the "Directors' Plan"), and the First Midwest Bancorp, Inc.
Nonqualified Stock Option Gain Deferral Plan (the "Gain Deferral Plan"), subject
to the terms, definition of terms, and conditions of the 1989 Plan, the
Directors' Plan and the Gain Deferral Plan which are incorporated herein by
reference, I elect to exercise my nonqualified stock options granted on the
_____ day of ______________, _______, and to purchase ______________ shares of
First Midwest Bancorp, Inc. $.01 par value common stock ("Stock") at the
exercise price of $________ per share.

In satisfaction of the option price (check one of the two following lines):

                             _______ enclosed are

                             _______  I hereby affirm ownership of

______ shares of previously acquired Stock. I hereby attest that the shares of
stock hereby tendered (or tendered through my affirmation of ownership) in
satisfaction of the Option price have been owned by me for a period of at least
six months prior to the date on which I executed this Notice. Furthermore, I
will provide evidence of such ownership as may be requested.

Additionally, I understand that, for 1989 Plan stock option exercises, the
excess of the fair market value of the shares acquired in this exercise, over
the exercise price of the shares of Stock purchased, is subject to current
Social Security taxation for this tax year. I further understand that once the
Fair Market Value of the shares acquired is established, I will be required to
remit this taxable amount to First Midwest Bancorp, Inc. prior to the shares
being issued. To satisfy such withholding, the taxes will be paid in accordance
with Part Three of this Form.

The specific amount conforming to the exercise election above is detailed on
Part Two of this Form, attached hereto and incorporated by reference.

          as aforesaid, or if for any reason such designation shall be
          ineffective, in whole or in part, the distribution that otherwise
          would have been paid to such Participant shall be paid to his estate
          and, in such event, the term "beneficiary" shall include his estate.

                              SUMMARY DESCRIPTION

                                January 1, 2000

                           *************************

FEATURES OF THE DEFERRED COMPENSATION PLAN FOR DIRECTORS

First Midwest Bancorp, Inc. ("First Midwest") has established a Deferred
Compensation Plan for Directors ("Directors Plan"or "Plan") to afford
nonemployee directors the opportunity to defer receipt of 100% or 50% of their
directors' fees and to invest the same in various investment alternatives
offered under the Directors Plan, including a First Midwest Stock Fund. Once
made, Directors may elect to change their deferral election, but such change
will only be effective for directors' fees earned in the calendar year
subsequent to the year in which change in election is made.

First Midwest has established a Grantor Trust to secure the account balances of
participants in the Directors Plan. The Grantor Trust offers security to
participants as well as flexibility with respect to investment options for
participant account balances.

First Midwest's obligations to Directors Plan participants as well as the
available investment elections and the procedures for distribution upon
termination as a Director of First Midwest are as follows:

     1.   Securing of Director Account Balances
          -------------------------------------
          Although the Directors Plan participants will continue to be unsecured
          creditors of First Midwest (as is required by IRS regulations to
          preserve the nontaxability of funds to the participants until
          distribution), the Directors Plan, nonetheless, provides a vehicle for
          segregating the participants' funds from the general operating
          accounts of First Midwest.

     2.   Expansion of Investment Elections
          ---------------------------------
          The establishment of the Directors Plan also provides a vehicle for
          expanding investment options to the participants. Although First
          Midwest is not obligated to provide such investment elections to the
          participants (again, this is required by IRS regulations in order to
          preserve the nontaxability referred to above), First Midwest intends
          to direct the Trustee to credit earnings and losses on the basis of
          investment elections selected by the participants.

     3.   Distributions to Participants
          -----------------------------
          Upon a participant's termination from the Directors Plan (as a result
          of resignation as a Director, retirement or death), the Trustee will
          make distributions in accordance with the instructions on the
          Directors Plan Election of Form of Benefit Distribution Form directly
          to the participant from the Directors Plan funds. It should be noted
          that, although a participant's account balance is not taxable while
          the participant remains a director, such balance becomes taxable upon
          distribution.

ADMINISTRATION OF THE DIRECTORS PLAN

The administration of the Directors Plan will be completely outsourced to a
third party Trustee.

                                       1
<PAGE>

The responsibilities of the Trustee are as follows:

     .    The Trustee will administer all recordkeeping functions with quarterly
          statements coming directly from the Trustee within 30 days after
          quarter end.

     .    The Trustee will credit earnings and losses on the basis of investment
          elections made by each participant.

     .    Changes in investment elections will be permitted once per month.

     .    Distributions from the Directors Plan and the related income tax
          reporting will be handled through the Trustee.

ELECTION TO DEFER

Once you have elected to participate in the Directors Plan, your participation
will begin with the next payment of directors' fees (for new Directors in the
Directors Plan who elect to participate in the first 30 days after becoming
eligible) or for directors' fees earned for the calendar year following the year
in which the election to participate is made (for existing Directors).

To begin participation, the Director must complete the Election Form which
includes the election to defer directors' fees and the election of frequency of
benefit distributions. The Election Form/Election of Form of Benefit
Distribution Form is attached as Exhibit A to this Summary Description.

INVESTMENT ELECTIONS

Your account balance in the Directors Plan can be invested in several different
investment alternatives; both mutual funds and a First Midwest Stock Fund.

In order to invest your account balance under the Directors Plan, you must
complete an Investment Election Form. You will be provided with a prospectus
covering the mutual funds investment elections and a summary sheet describing
the investment performance and objective of each fund. The Investment Election
Form is attached as Exhibit B to this Summary Sheet.

PROCEDURES FOR MAKING CHANGES

          based on the Election of Form of Benefit Distribution that you
          completed upon admittance to the Plan.

          All account balances due to be distributed with a value of $25,000 or
          less will be distributed in a lump sum. Distributions with a value in
          excess of $25,000 will be distributed in accordance with the
          participant's election. The first distribution will be in the first 30
          days of the calendar quarter following the later of the distribution
          event or the date elected by the participant as described below.

          A participant will be asked to make a distribution election upon
          admittance to the Directors Plan. Distributions are currently allowed
          in a lump sum or in annual or quarterly installments of up to 15
          years. Additionally, a participant can elect to defer the receipt of
          distributions from the Plan (whether such distributions are in a lump
          sum or in installments) for up to 5 years. For example, a participant
          may elect to receive his/her first annual or quarterly distribution
          for 3 years from the date of retirement or termination. After the 3
          year period has expired, annual or quarterly distributions will begin
          within 30 days after the end of the calendar quarter that is 3 years
          from the date of the distribution event.

          A distribution election can be changed, but only for a distribution
          event which occurs both during the calendar year following the year in
                             ----
          which the election is changed and six months prior to the distribution
                                        ---
          event. For example, if a participant originally elects a distribution
          of five annual installments and on November 1, 1999 changes that
          election to 10 annual installments, the change in distribution
          election to 10 years would only be applicable for distribution events
          occurring after May 1, 2000 (the calendar year following, and six
          months after, the date on which the change was made). These waiting
          periods will not apply to a change which is made prior to a
          change-in-control of First Midwest as defined in the Plan, and
          applicable to a distribution event which occurs on or after a change-
          in-control. However, this exception is subject to approval by the
          Compensation Committee of First Midwest Bancorp, Inc. as further
          discussed in the Plan Document.

          If, for any reason, a participant does not elect a form of
          distribution, the default option for distribution to that participant
          will be 5 annual installments.

          To provide maximum flexibility, the Directors Plan also permits
          certain short-term payouts and a withdrawal election. The short-term
          payouts provide participants with access to all or a portion of
          specifically identified deferral amount, plus earnings, payable to the
          ---------------------------------------
          participant in 3 years or more after the end of the plan year in which
          the short-term payout election is made. Short-term payouts are only
          made in lump-sums. The withdrawal election feature permits a
          participant to withdraw his/her entire account balance at any time
          less a 10% withdrawal penalty and forfeiture of participation in the
          Directors Plan for one full plan year.

          If you wish to take advantage of either a short-term payout or
          withdrawal election, please contact the First Midwest Corporate
          Secretary's Office.

Instructions:
-------------

List each beneficiary who is to share in any payment due under the Plan. State
specifically in Column (D) what percentage of the total amount is to be received
by each beneficiary.

In the event that all of the above-named beneficiaries shall predecease me, or
if there is no doubt as to the right of any beneficiary, First Midwest Bancorp,
Inc. shall make payments, which would otherwise have been made to such
beneficiary, to my estate; and in such event, First Midwest shall not be under
any further liability.

This beneficiary designation cancels and supersedes any previous designation
that I may have made with respect to this Plan. The designation is effective as
of the date this form is signed by me. I withhold the right to change this
designation at any time by filing a new beneficiary form with the Corporate
Secretary of the Company.
