     Dear Sirs:

     From time to time, First Midwest Bancorp, Inc. (the "Company") may offer
     and sell to you, on terms to be negotiated between us, shares of the
     Company's Common Stock (no par value) ("Common Stock") that are registered
     under the Securities Act of 1933 (the "Act") pursuant to Registration
     Statement No. 33-61467 on Form S-3 (the "Registration Statement") filed
     with the Securities and Exchange Commission (the "Commission") (the
     "Shares").  In connection with each such offer and sale, the Company hereby
     represents and warrants to you, and agrees with you, as follows:

     1.    At the time the Registration Statement became effective, it complied
           in all material respects with the requirements of the Act and the
           rules and regulations thereunder and did not contain an untrue
           statement of a material fact or omit to state a material fact
           required to be stated therein or necessary to make the statements
           therein not misleading.  At the time of any sale of Shares to you and
           at the settlement date for such sale, the prospectus furnished to you
           for use in connection with your reoffer and resale of the Shares (the
           "Prospectus") will not contain an untrue statement of a material fact
           or omit to state a material fact necessary in order to make the
           statement therein, in the light of the circumstances under which they
           were made, not misleading.

     2.    The documents incorporated or to be incorporated by reference into
           the Prospectus, at the time they were or hereafter are filed with the
           Commission complied and will comply in all material respects with the
           requirements of the Securities Exchange Act of 1934 and the rules and
           regulations thereunder  and, when read together and with the other
           information included in or incorporated by reference in the
           Prospectus, at the time the Registration Statement became effective
           and at the time of any sale of Shares to you and at the settlement
           date for such sale, did not or will not contain an untrue statement
           of a material fact or omit to state a material fact necessary in
           order to make the statements therein, in the light of the
           circumstances under which they were made, not misleading.

     3.    The Company meets the requirements for the use of Form S-3 under the
           Act.

     4.    The Company agrees (a) to deliver to you certificates for any Shares
           sold to you on the settlement date of such sale, such certificates to
           be in such denominations and registered in such form as you may
           request, (b) to take such action as may be necessary to qualify the
           Shares for offering and sale  under the securities laws of such
           jurisdictions as you may request and to comply with such laws so as
           to permit the continuance of sales and dealings therein for as long
           as you may request, (c) to furnish you with copies of the Prospectus
           in such quantities as you may from time to time request and to update
           the Prospectus as necessary for as long as you may be required to
           deliver a Prospectus in connection with the reoffer or resale of
           Shares (provided that you will bear the expense of updating the
           Prospectus at any time after nine months from the date of any sale to
           you).

 
     5.    Settlement of any sale of Shares shall be subject to the
           representations and warranties contained herein being true and
           accurate as of the settlement date of such sale and to the absence as
           of such settlement date of any material loss or interference with the
           Company's business since the sale of such Shares. The Company agrees
           to deliver to you upon your request, on the settlement date for any
           sale of Shares, a certificate of such of its officers as you may
           reasonably specify to the foregoing effect.

     6.    The Company agrees to indemnify and hold you harmless, together with
           each of your officers, directors and controlling persons, against and
           from any losses, claims, damages or liabilities to which you may
           become subject and that arise out of any untrue statement or alleged
           untrue statement of a material fact contained in the Registration
           Statement, any Prospectus or any document incorporated by reference
           therein, or arise out of or are based upon  the omission or alleged
           omission to state therein a material fact required to be stated
           therein or necessary  to make the statements contained therein not
           misleading, and will reimburse you periodically upon demand for any
           legal or other expenses you incur in connection with investigating or
           defending any such action or claim.

     7.    The Company agrees to take no action designed to or that may
           reasonably be expected to cause or result in stabilization or
           manipulation of the price of the Common Stock.

     8.    The Company understands that Keefe, Bruyette and Woods, Inc. may
           retain some of the Shares in its own investment account, or in the
           investment account of its Pension and Profit-Sharing Plan.

     If the foregoing correctly reflects our understanding, please sign and
     return the enclosed copy of this agreement.

     Very truly yours,

     FIRST MIDWEST BANCORP, INC.
