                 TCF and Standard Financial Agree to Merge
                        Creating $10 Billion Company


               PR Newswire - March 17, 1997  08:42

               MINNEAPOLIS, March 17 /PRNewswire/ -- TCF Financial
               Corporation (TCF) (NYSE: TCB) and Standard Financial, Inc.
               (Standard) (Nasdaq-NNM: STND) today announced a definitive
               agreement to merge, creating a company with a combined $10
               billion in assets and providing access to 276 financial
               services offices and more than 900 ATMs in five midwestern
               states.

               The transaction is structured as a cash election merger,
               providing for an exchange of TCF common stock and cash
               for Standard shares.  TCF will be the surviving
               corporation in the merger.  The transaction is expected
               to have an aggregate value, based on the closing price of
               TCF common stock on March 14, of approximately $424
               million, or approximately $25 per Standard common share. 
               The transaction value is approximately 160 percent of
               Standard's book value.  TCF expects the merger to be
               accretive to both reported and cash earnings in 1998.

               TCF Chairman and Chief Executive Officer William A.
               Cooper said that Standard's retail branch network
               complements TCF's 35 Illinois bank branches, 26 of which
               are in the Chicago area.  "This union significantly
               expands our profitable and growing Illinois franchise,"
               said Cooper.  "Chicago has long been an attractive market
               for TCF -- a large, urban-based population receptive to
               banking convenience -- and Standard has an exemplary
               tradition of meeting community banking needs."  Cooper
               added that no bank branches will be closed in connection
               with the merger.

               "Joining TCF will accelerate our transformation to a
               leading consumer bank, for the benefit of our
               shareholders, customers, and the communities we serve,"
               said Standard Chairman and President David Mackiewich. 
               "We will have access to a broader range of products and
               services, convenient banking locations -- including
               seven-day banking at supermarkets and 248 Cash Station
               ATMs -- and the financial resources of a dynamic regional
               bank."

               "We believe this merger will produce long-term revenue
               enhancements and meaningful cost savings," said Cooper. 
               He noted that the strategic plan for improving the
               Chicago franchise follows TCF's community banking
               philosophy: increasing lower interest-cost checking,
               savings, and money market deposit  accounts; increasing
               higher-yielding consumer and commercial loans;
               introducing complementary products and services such as
               annuities, mutual funds, debit cards; and consolidating
               back-office operations.

               For Standard's stockholders, the transaction will be
               structured as a cash election merger in which holders of
               Standard's stock will have the right to choose either
               cash or TCF common stock, or a combination of the two. 
               Between 40 percent and 60 percent of the purchase price
               will be paid in shares of TCF common stock, and the
               remainder will be paid in cash.  The transaction will be
               a tax-free exchange for Standard's stockholders to the
               extent they receive shares of TCF common stock.

               The exchange ratio for shares of Standard stock will
               depend on the average trading price of TCF stock during
               the 30 trading days preceding the merger.  If the average
               trading price of TCF stock during that period is between
               $43.75 and $47.75, each Standard share will be converted
               into the right to receive consideration having an
               aggregate value between $24.69 and $25.81.  If the
               average trading price of TCF stock is below $43.75 but
               greater than or equal to $37.50, each Standard share will
               be converted into the right to receive consideration
               having an aggregate value of $24.69.  If the average
               trading price of TCF stock is above $47.75 but less than
               or equal to $54.00, each Standard share will be converted
               into the right to receive consideration having an
               aggregate value of $25.81.

               The definitive agreement was signed after completion of
               due diligence and approval of both companies' boards of
               directors. It is subject to approval by Standard's
               stockholders, and required regulatory filings and
               approvals.  The merger is expected to close in the third
               quarter of 1997 and be accounted for as a purchase
               transaction.  Standard has agreed to pay a $15 million
               termination fee if the merger agreement is terminated
               under certain circumstances.

               In connection with the transaction, TCF will record
               intangibles of approximately $200 million.

               After the merger, Standard's bank branches will be
               combined with TCF Bank Illinois.  The directors of
               Standard will join TCF Bank Illinois' board of directors. 
               Mackiewich will become executive chairman of TCF Bank
               Illinois and a director of TCF Financial Corporation. 
               Michael B. Johnstone, president and chief executive
               officer of TCF Bank Illinois, will continue in that
               capacity.  TCF will contribute $1 million over five years
               to Illinois community organizations, consistent with
               TCF's philanthropic giving program which is focused on
               housing and economic development in low-income
               communities, and K-12 education reform.

               In connection with the merger, Standard has announced
               that it has postponed its annual meeting and plans to
               call a special meeting at which it will seek stockholder
               approval of the merger.  Standard is a community-oriented
               thrift institution with $2.4 billion in assets and 14
               full-service offices on the southwest side of Chicago and
               in the nearby southwestern and western suburbs. 
               Excluding a regulatory special assessment, Standard
               reported record 1996 earnings of $17.7 million, or $1.13
               per share, a return on average assets of 0.78 percent,
               and a return on average equity of 6.60 percent.

               TCF is a Minneapolis-based stock savings bank holding
               company with $7.1 billion in assets and more than 260
               financial services offices.  Its bank subsidiaries
               operate in Minnesota, Illinois, and Wisconsin as TCF
               Bank, and in Michigan and Ohio as Great Lakes Bancorp.

               title insurance, annuity and mutual fund sales companies. 
               Excluding a regulatory special assessment, TCF reported
               record 1996 earnings of $107.4 million, or $3.04 per
               share, a return on average assets of 1.56 percent, and a
               return on average common equity of 20.22 percent.  TCF
               intends to convert its federal savings bank subsidiaries
               into national banks in the 1997 second quarter, pending
               all required regulatory approvals.
