                          FIRST MIDWEST BANCORP, INC.
                 NONQUALIFIED STOCK OPTION - GAIN DEFERRAL PLAN


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 establishes the First Midwest Bancorp, Inc.
Nonqualified Stock Option - Gain Deferral Plan (the "Plan") as hereinafter
provided:


                                   ARTICLE I
                                    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.  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.  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.

     Employees who shall participate in the Plan; provided, however, that such
     Employees are members of a select group of management or highly compensated

     401(a)(1) of ERISA as interpreted by the Department of Labor.

3.2  Participation.  An Employee shall commence participation in the Plan as of
     the date designated by the Committee.  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 Valuation Date that precedes or
     coincides with the date of such suspension or termination without such
     Participant's consent.  An Employee shall cease to be a Participant when he
     terminates employment with the Company and all Employers and the balance in
     his Account is distributed to him or on his behalf.

                                       3

 
3.3  Deferral Election Procedure.

        (a) 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, a Deferral Election Form must be executed by the
     Participant: (i) in a calendar year preceding the exercise of such Options;
     and (ii) at least six months prior to the exercise of such Options;
     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 after the date of such Deferral Election
     Form without regard to clauses (i) and (ii).

        (b) 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.  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.] As soon as practicable after receipt of the tendered Stock
     or the affirmation of ownership of Stock, 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.

                                   ARTICLE IV
                              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 Sections 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 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; (b) the exercise
     complies with all of the applicable terms of the Option and of the Stock
     Plan; and (c) 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:

     (a)  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.

     (b)  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.

     (c)  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.

     (d)  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.

                                       5

 
                                   ARTICLE V
                              PAYMENT OF BENEFITS

5.1  Entitlement to Benefit Payments.  Upon a Participant's separation from
     service from the Company and all Employers, the Participant shall be
     entitled to his Account balance payable by the Company or by his Employer
     in the form set forth in 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 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.  The Participant's Account balance shall
     be paid to him in five annual installments commencing on a date which is
     within ninety (90) days following his separation from service from the
     Company and all Employers; provided, however, that if a Participant has
     requested that his Account balance be paid in a lump sum or in up to ten
     (10) annual installments, in accordance with such prior written notice
     requirements as the Committee may adopt in its sole discretion, then his
     Account balance shall be paid in such other manner and time.  A Participant
     may request to change the form and commencement date for the payment of
     benefits, which the Committee, in its sole discretion, may honor.
     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.

5.3  Hardship Withdrawals.  In the event of a Participant's immediate and
     unforeseeable financial hardship, the Committee may, in its sole
     discretion, pay out all or part of such Participant's Vested Account
     Balance to the extent necessary to relieve such hardship.

                                   ARTICLE VI
                     PAYMENT OF BENEFITS ON OR AFTER DEATH

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:

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

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

     (c)  to the Participant's estate.

                                  ARTICLE VII
                                 ADMINISTRATION

7.1  General.  The Administrator shall be the Committee, or such other person or
     persons as designated by the Board or the Committee.  Except as otherwise
     specifically provided in the Plan, the Administrator shall be responsible
     for the administration of the Plan.  The Administrator shall be the "named
     fiduciary" within the meaning of Section 402(c)(2) of ERISA.

7.2  Administrative Rules.  The Administrator may adopt such rules of procedure
     as it deems desirable for the conduct of its affairs, except to the extent
     that such rules conflict with the provisions of the Plan.

7.3  Duties.  The Administrator shall have the following rights, powers and
     duties:

     (a)  The decision of the Administrator in matters within its jurisdiction
          shall be final, binding and conclusive upon each Employer and upon any
          other person affected by such decision, subject to the claims
          procedure hereinafter set forth.

     (b)  The Administrator shall have the duty and authority to interpret and
          construe the provisions of the Plan, to decide any question which may
          arise regarding the rights of Employees, Participants and
          beneficiaries, and the amounts of their respective interests, to adopt

                            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 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.

9.2  Termination.  The Company reserves the right to terminate the Plan at any
     time.  No termination shall, without the Participant's 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 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.

      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.

      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

                                     TRUST

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, duties or 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 offer is extended with
      respect to the Shares of the Company, 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

 
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.

                             *    *    *    *    *



IN WITNESS WHEREOF, the Company has caused this Plan to be executed by its duly

                 NONQUALIFIED STOCK OPTION - GAIN DEFERRAL PLAN

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

To:     Office of the Compensation Committee of the Board of Directors:

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 "Plan"), subject to the
terms, definition of terms, and conditions of the 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 Plan or, if later, the date I was first designated as
eligible to participate in the 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 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
on the date of Option exercise.

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 as follows:

        ______  % of the total number of Profit Shares applicable to all Options
        so exercised.
