STANDARD BANCSHARES, INC. AND SECURITY FINANCIAL BANCORP, INC. ANNOUNCE MERGER

HICKORY HILLS, IL/ST. JOHN, IN (February 7, 2003) - Standard Bancshares, Inc.,
parent company of Standard Bank and Trust Co. (Standard Bank), and Security
Financial Bancorp, Inc. (Nasdaq Small Cap: SFBI), parent company of Security
Federal Bank & Trust, jointly announced today that they have entered into a
definitive agreement providing for the merger of Security Financial Bancorp with
and into Standard Bancshares, pending regulatory approval and approval by the
Security Financial Bancorp shareholders.

At December 31, 2002, Standard Bancshares had assets of $954 million and
Security Financial Bancorp had $199 million in assets. Security Federal Bank &
Trust's six branch network will be integrated into Standard Bank after the
transaction is completed. The transaction is expected to be completed in the
second quarter of 2003.

Pursuant to the merger agreement, shareholders of Security Financial Bancorp
will receive $24.00 in cash for each share of common stock of Security Financial
Bancorp. The transaction has a total cash value on a fully diluted basis of
approximately $45.9 million.

Standard Bank was founded in 1947, and is the privately held subsidiary of
Standard Bancshares, Inc. of Hickory Hills. Standard Bank currently has 20 bank
branches located in the southern and western regions of the Chicagoland area
encompassing Cook, DuPage, Will and Grundy counties.

Security Federal Bank & Trust, headquartered in St. John, Indiana, currently has
six locations located throughout northwest Indiana, immediately southeast of
Chicago; five in Lake County and one in Porter County. Customers of Security
Federal Bank & Trust will benefit from access to a broader range of products and
services and an expanded network of banking facilities offered through Standard
Bank.

"This transaction provides excellent opportunities for both our bank and our
customers. The acquisition of Security Financial continues our strategy of
expanding our presence into new communities while continuing to provide
outstanding customer service", said Lawrence P. Kelley, President and Chief
Executive Officer of Standard Bancshares. "In addition to increasing our
customer base, this acquisition allows all of our customers the convenience of
more branch and ATM locations as well as an increased breadth of products and
services."

fine organization like Standard Bancshares. Our Board of Directors is very
pleased with the enhanced value this transaction offers to our shareholders.
Additionally, the combined company will create new and exciting opportunities
for our customers, and a great benefit to the communities in which we do
business." John Palmer, Chairman of the Board of Security Financial Bancorp,
stated "This acquisition will allow our customers more convenience with expanded
full service banking centers and ATM locations, while at the same time providing
our employees with additional opportunities."

This is the fourth significant bank acquisition for Standard Bancshares. The
Bank of Hickory Hills, based in Hickory Hills, was acquired in 1986. The second
transaction occurred in 1999 with the acquisition of Exchange Bank - located
throughout Grundy County and headquartered in Gardner, IL.

Just last December, Standard Bancshares announced that it entered into an
agreement to acquire the parent company of BankChicago, which will, pending
regulatory and shareholder approval, add six bank branches; three in Chicago,
two in Lyons, IL and one in Oak Forest, IL.

When all acquisitions are completed, Standard Bank will have assets of
approximately $1.4 billion and thirty-two full service banking centers located
throughout the Chicagoland area encompassing Cook, DuPage, Will, Grundy and the
