Item 8.01  Other Events

On December 21, 2009, the United States Department of the Treasury (“Treasury”) closed the secondary public offering of 3,199,988 warrants (the “Warrant Offering”), representing the right to purchase an aggregate of up to 3,199,988 shares of the common stock, par value $.01 per share (the “Common Stock”) of TCF Financial Corporation (“TCF”) at an exercise price of $16.93 per share (the “Warrants”), pursuant to that certain Underwriting Agreement dated December 15, 2009 (the “Underwriting Agreement”) by and among TCF, Treasury and Deutsche Bank Securities Inc. (the “Underwriter”).  The public offering price of the Warrants was equal to the auction clearing price of $3.00.  TCF did not receive any of the proceeds of the Warrant Offering.  The Warrant Offering was only made under a prospectus supplement and the accompanying prospectus filed with the Securities and Exchange Commission (the “Commission”) pursuant to the Company’s automatic shelf registration statement on Form S-3 (Registration No. 333-156068).

In connection with the Warrant Offering, the Company and certain of its officers and directors have agreed to enter into 45-day “lock-up” agreements in substantially the form included in the Underwriting Agreement and subject to customary exceptions.  Additionally, the Company entered into that certain Warrant Agreement dated December 15, 2009 (the “Warrant Agreement”) with Computershare, Inc. and Computershare Trust Company, N.A., as warrant agent.

The foregoing description of the Underwriting Agreement, Warrant Agreement, Warrants and other documents relating to the transaction does not purport to be complete and is qualified in its entirety by reference to the full text of these documents and securities, forms or copies of which are incorporated by reference or are attached as exhibits to this Current Report on Form 8-K and are incorporated herein by reference.
