Dear Shareholders,

This letter provides a brief update on our financial performance through the
second quarter of 2003. In response to the requests of a number of shareholders,
we have significantly shortened the length of our cover note. But as usual, we
have attached the July 17, 2003 news release of our earnings for the quarter
ended June 30, 2003 for your information.

HIGHLIGHTS FOR SECOND QUARTER OF 2003

We again achieved record earnings for this quarter while deposit and asset
levels also hit new record highs. Here is a summary of our financial results and
accomplishments for the three months ending June 30, 2003:

-        Net income reached $9.0 million for the quarter ended June 30, 2003, an
         increase of 43% over the second quarter of 2002;

-        On a per share basis, net income totaled $0.49 per diluted common share
         for the second quarter of 2003, a 32% increase as compared to year ago.
         The lower growth rate in the earnings per share as compared to net
         income was primarily due to the issuance of 1,362,750 additional shares
         of common stock in mid-2002;

-        Return on average equity for the quarter increased to 14.95%, up from
         14.75% for the second quarter of 2002;

-        Total assets rose to $4.13 billion as of June 30, 2003, an increase of
         $913 million, or 28%, compared to a year ago;

-        Total deposits reached $3.42 billion as of June 30, 2003, an increase
         of $811 million, or 31%, compared to June 30, 2002;

-        Total loans grew to $2.90 billion as of June 30, 2003, an increase of
         $587 million, or 25%, compared to a year ago;

-        In spite of continuing record low interest rates, net interest income
         totaled $28.3 million, an increase of 16% versus a year ago.
         Non-interest income totaled $19.1 million, an increase of 39% over the
         comparable period of 2002. Non-interest income represented 40% of our
         net revenues (non-interest income plus net interest income) in the
         second quarter of this year. Our long-term goal is to increase that
         ratio to 50%;

-        Our net overhead ratio, a measure of operating efficiency, improved to
         1.16% in the second quarter of 2003 from 1.63% in the prior year
         quarter;

-        Our asset quality remains strong and very manageable. Non-performing
         assets as a percent of total assets were 0.35%, a slight improvement
         over year ago levels of 0.37%;

-        In April we opened North Shore Community Bank & Trust's beautiful new
         main facility in Skokie. In addition to adding significantly more
         space, it contains drive-through banking lanes and safe deposit boxes;

-        Construction is well under way on two additional bank
         facilities--Libertyville Bank & Trust's new South Libertyville facility
         with drive-through lane facilities and Cary Bank & Trust's (a branch of
         Crystal Lake Bank & Trust) new main facility with drive-through lanes;

-        We have hired a management team and are moving ahead aggressively with
         the launch of de novo community bank #8, and;

-        In June 2003, we announced the signing of an agreement to acquire
         Advantage National Bancorp, Inc., parent of Advantage National Bank.
         Advantage National Bank, also a de novo community bank, has locations
         in Elk Grove Village and Roselle, Illinois, and total assets of $107
         million as of June 30, 2003. This provides Wintrust a community bank
         entry into this important northwest Chicago area corridor.


SUMMARY

In summary, we are very pleased with the continued growth in earnings and assets
in the second quarter. We are working diligently to continue our unique growth
story while improving our earnings level.


                                  Yours truly,
