ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT. On March 17, 2005, Wintrust Financial Corporation (the "Company") granted Edward J. Wehmer, the Company's President and Chief Executive Officer, 45,000 restricted stock units pursuant to the Company's 1997 Stock Incentive Plan (the "Plan"). The restricted stock units were awarded to Mr. Wehmer as part of his long-term incentive compensation. The shares underlying the restricted stock units become fully vested not later than the earliest of (1) five years from the date of grant, or March 17, 2010; (2) termination of Mr. Wehmer's employment due to his permanent disability, death, retirement or a termination by the Company without Cause, or due to Mr. Wehmer's Constructive Termination (as defined in the Employment Agreement between the Company and Mr. Wehmer, dated January 31, 2005); or (3) a Change in Control (as defined in the Plan). If Mr. Wehmer's employment with the Company is terminated by the Company for Cause or by Mr. Wehmer other than due to his Constructive Termination prior to the first date upon which all the shares shall have become vested, the shares will be forfeited. The vested shares relating to the award will be distributed to Mr. Wehmer on the January 15th following the year in which Mr. Wehmer's employment terminates or at such other time as a deduction for compensation relating to the distribution of such shares will not be disallowed under Internal Revenue Code (the "Code") Section 162(m) and as complies with the requirements of Code Section 409(A). Mr. Wehmer will not have any rights as a shareholder with respect to any of the shares until he actually receives the shares. The dollar amount of any cash dividends that would have been payable on the shares will be converted into a number of restricted stock units equal to the number of shares of common stock that such dollar amount could have purchased at the closing price of the Company's common stock on the dividend payment date. In the event of the payment of any stock dividend, Mr. Wehmer will be entitled to receive an additional number of restricted stock units equal to the number of his restricted stock units then held multiplied by the per share number of shares of common stock distributed as a dividend. 2 SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
