Also, on August 10, 2009, Edward J. Wehmer, President, Chief Executive Officer and Director, adopted a structured, pre-arranged stock trading plan to sell shares of restricted stock in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934, as well as the policies of Wintrust with respect to insider sales.
The purpose of the plan is to provide Mr. Wehmer, who receives a substantial portion of his compensation in the form of equity awards, with the ability to sell restricted stock which vests periodically in an orderly manner and to avoid concerns about the timing of those transactions.
Mr. Wehmer's trading plan covers the sale of up to 10,000 shares of restricted stock, which were granted to Mr. Wehmer in January 2005. The shares of restricted stock may not be sold prior to their vesting on January 25, 2010. The plan is expected to terminate no later than August 1, 2010. The maximum number of shares that may be sold under the plan constitute less than 3% of Mr. Wehmer's beneficially owned holdings of Wintrust common stock (which excludes unvested restricted stock and unvested stock options).

FORWARD-LOOKING STATEMENTS
This Current Report on Form 8-K contains forward-looking statements within the meaning of federal securities laws. Forward-looking information in this document can be identified through the use of words such as "may," "will," "intend," "plan," "project," "expect," "anticipate," "should," "would," "believe," "estimate," "contemplate," "possible," and "point." The forward-looking information is premised on many factors, some of which are outlined below. The Company intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and is including this statement for purposes of invoking these safe harbor provisions. Such forward-looking statements may be deemed to include, among other things, statements relating to the Company's projected growth, anticipated improvements in earnings, earnings per share and other financial performance measures, and management's long-term performance goals, as well as statements relating to the anticipated effects on financial results of condition from expected developments or events, the Company's business and growth strategies, including anticipated internal growth, plans to form additional de novo banks and to open new branch offices, and to pursue additional potential development or acquisitions of banks, wealth management entities or specialty finance businesses. Actual results could differ materially from those addressed in the forward-looking statements as a result of numerous factors, including the following:
• Competitive pressures in the financial services business which may affect the pricing of the Company's loan and deposit products as well as its services (including wealth management services).

• Changes in the interest rate environment, which may influence, among other things, the growth of loans and deposits, the quality of the Company's loan portfolio, the pricing of loans and deposits and interest income.

• The extent of defaults and losses on our loan portfolio.

• Unexpected difficulties or unanticipated developments related to the Company's strategy of de novo bank formations and openings. De novo banks typically require 13 to 24 months of operations before becoming profitable, due to the impact of organizational and overhead expenses, the startup phase of generating deposits and the time lag typically involved in redeploying deposits into attractively priced loans and other higher yielding earning assets.

• The ability of the Company to obtain liquidity and income from the sale of premium finance receivables in the future and the unique collection and delinquency risks associated with such loans.

• Failure to identify and complete acquisitions in the future or unexpected difficulties or unanticipated developments related to the integration of acquired entities or assets into the Company.

• Legislative or regulatory changes or actions, or significant litigation involving the Company.

• Changes in general economic conditions in the markets in which the Company operates.

• The ability of the Company to receive dividends from its subsidiaries.

• The loss of customers as a result of technological changes allowing consumers to complete their financial transactions without the use of a bank.

• The ability of the Company to attract and retain senior management experienced in the banking and financial services industries.

• The risk that the terms of the U.S. Treasury Department's Capital Purchase Program could change.

• The other risk factors set forth in the Company's filings with the Securities and Exchange Commission.

Therefore, there can be no assurances that future actual results will correspond to these forward-looking statements. The reader is cautioned not to place undue reliance on any forward looking statement made by or on behalf of Wintrust. Any such statement speaks only as of the date the statement was made or as of such date that may be referenced within the statement. The Company undertakes no obligation to release revisions to these forward-looking statements or reflect events or circumstances after the date of this press release. Persons are advised, however, to consult further disclosures management makes on related subjects in its reports filed with the Securities and Exchange Commission and in its press releases.

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.
