Exhibit 99

Report of Independent Registered Public Accounting Firm

The Board of Directors

First Midwest Bancorp, Inc.

We have reviewed the consolidated statement of financial condition of First Midwest Bancorp, Inc. and subsidiaries as of June 30, 2010, and the related consolidated statements of income for the three-month and six-month periods ended June 30, 2010 and 2009, and the consolidated statements of changes in stockholders’ equity and cash flows for the six-month periods ended June 30, 2010 and 2009. These financial statements are the responsibility of the Company's management.

We conducted our review in accordance with standards of the Public Company Accounting Oversight Board (United States).  A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statement of financial condition of First Midwest Bancorp, Inc. and subsidiaries as of December 31, 2009, and the related consolidated statements of income, changes in stockholders' equity, and cash flows for the year then ended (not presented herein) and in our report dated March 1, 2010, we expressed an unqualified opinion on those consolidated financial statements.  In our opinion, the information set forth in the accompanying consolidated statement of financial condition as of December 31, 2009, is fairly stated, in all material respects, in relation to the consolidated statement of financial condition from which it has been derived.
