Minneapolis, Minnesota 55402, and its telephone number is (612) 661-6500.
 
                              RECENT DEVELOPMENTS
 
    On January 16, 1997, TCF Illinois acquired the stock of BOC Financial
Corporation ("BOC") and its wholly owned indirect subsidiary, Bank of Chicago,
s.b., an Illinois state-chartered savings bank ("Bank of Chicago"). Effective
April 7, 1997, Bank of Chicago was merged with and into TCF Illinois, with TCF
Illinois as the resulting institution. Bank of Chicago operated three branches
in the Chicago, Illinois area, and BOC had total assets of $183.1 million at
December 31, 1996.
 
    On February 28, 1997, TCF and Winthrop Resources Corporation ("Winthrop")
signed an agreement and plan of reorganization (the "Winthrop Merger
Agreement"). Winthrop, with total assets of $370 million at March 31, 1997,
specializes in leasing high-tech and business equipment. Under the Winthrop
Merger Agreement, a newly formed, wholly owned subsidiary of TCF will be merged
with and into Winthrop (the "Winthrop Merger"), and Winthrop will become a
wholly owned subsidiary of the Company. After the Winthrop Merger, TCF intends
to contribute Winthrop to TCF Minnesota. Subject to satisfaction or waiver of
the conditions precedent to consummation of the Winthrop Merger, including but
not limited to the receipt of the requisite shareholder and regulatory
approvals, and treatment of the Winthrop Merger as a pooling of interests for
accounting purposes, and neither party exercising its right to terminate the
Winthrop Merger Agreement under certain circumstances, TCF expects to consummate
the Winthrop Merger in June or July, 1997. At the effective time of the Winthrop
Merger, up to 7,050,000 registered shares of Common Stock will be exchanged for
all of the outstanding shares of Winthrop's common stock in a tax-free exchange
based on an exchange ratio of 0.7766 of a share of Common Stock for one share of
Winthrop common stock. Winthrop has the right to terminate the transaction if
the average of the daily closing price of the Common Stock for a period of time
prior to the Winthrop Merger is less than $42.30 per share. TCF has the right to
terminate the transaction if the average of the daily closing price of the
Common Stock is more than $51.70 per share. The period for determining the
average closing price of the Common Stock is the 30 trading days ending three
business days prior to the later of the last
 
                                       4
<PAGE>
shareholders' meeting to vote on the Winthrop Merger or the date of the last
regulatory approval. Thus, there can be no assurance that the Winthrop Merger
will be consummated.
 
    On March 16, 1997, TCF and Standard Financial, Inc. ("Standard") signed an
agreement and plan of reorganization (the "Standard Merger Agreement"). Standard
and its wholly owned subsidiary, Standard Federal Bank for savings, a federal
savings bank ("Standard Bank"), headquartered in Chicago, Illinois, had total
assets of $2.5 billion and Standard Bank had operated 14 branches at March 31,
1997. Under the Standard Merger Agreement, Standard will be merged into TCF
Illinois (the "Standard Merger"). The Standard Merger is structured as a cash
election merger in which Standard stockholders will have the right to choose
either cash or Common Stock, or a combination of the two. Between 40% and 55.5%,
as determined by TCF, of the estimated purchase price of $419 million will be
paid in shares of Common Stock with the remainder paid in cash. The Standard
Merger will be accounted for by the purchase method of accounting. Consummation
of the Standard Merger is subject to regulatory approval and certain other
conditions and, assuming satisfaction or waiver of such conditions, is expected
to occur by October 31, 1997. However, the transaction is subject to various
conditions, including requisite regulatory approvals and clearances, and rights
of termination, including the right of Standard to terminate if the average of
the daily closing price of the Common Stock for a period of time prior to the
Standard Merger is below $37.50 per share. The period for determining the
average closing price of the Common Stock is the 30 trading days ending three
business days prior to the later of the Standard shareholder's meeting to vote
on the Standard Merger or the date of the last regulatory approval (the
"Standard Determination Period"). Thus, there can be no assurance that the
Standard Merger will be consummated.
 
    Neither the Winthrop Merger nor the Standard Merger is conditioned upon
consummation of the other merger.
 
    On May 12, 1997, TCF called for redemption the 7 1/4% Convertible
Subordinated Debentures due 2011 of Great Lakes Bancorp (the "Great Lakes
Debentures") which TCF assumed in connection with its acquisition of Great Lakes
Bancorp, A Federal Savings Bank ("Great Lakes") in February 1995. As of May 12,
1997, $7.1 million principal amount of Great Lakes Debentures was outstanding.
The Great Lakes Debentures are convertible into Common Stock at a conversion
price of $17.04 per share of Common Stock.
 
    On May 23, 1997, Great Lakes Ohio entered into a purchase and sale agreement
pursuant to which the eight branches of Great Lakes Ohio, representing $130
million in deposits, will be sold to The Fifth Third Bank headquartered in
Cincinnati, Ohio.
 
                                  THE OFFERING
 
    TCF is offering the shares of Common Stock (the "Offering") in connection
with the Winthrop Merger. TCF is planning to sell up to 800,000 shares of Common
Stock in order to meet one of the criteria for the Winthrop Merger to be
accounted for as a pooling of interests in accordance with generally accepted
accounting principles. The shares offered hereby will be sold prior to the
effective time of the
 
                                       5

Winthrop Merger. However, there can be no assurance that either or both of the
Winthrop Merger and the Standard Merger will be completed.

                        DESCRIPTION OF TCF CAPITAL STOCK
 
GENERAL
 
    TCF is authorized to issue 170,000,000 shares of capital stock, par value
$.01 per share, consisting of 140,000,000 shares of Common Stock and 30,000,000
shares of preferred stock. As of April 30, 1997, there were issued and
outstanding 34,612,658 shares of Common Stock, and 346,127 shares of Series A
Junior Participating Preferred Stock were reserved for issuance upon the
exercise of certain preferred share purchase rights (the "Rights") described
below.
 
COMMON STOCK
 
    GENERAL.  TCF common stockholders have no preemptive rights. The outstanding
shares of Common Stock are, and the Common Stock offered hereby will be, fully
paid and nonassessable. Each outstanding share of Common Stock also includes,
and each share offered hereby will include, one Right.
 
    VOTING.  TCF common stockholders are entitled to one vote for each share
held on each matter submitted to a vote of the holders of Common Stock.
Cumulative voting for the election of directors is not permitted.
 
    DIVIDENDS, DISTRIBUTIONS AND REDEMPTIONS.  Subject to the preferential
dividend rights of any issued and outstanding preferred stock, TCF's common
stockholders are entitled to receive dividends as and when declared by the Board
of Directors of TCF. Under Delaware corporate law, TCF may declare and pay
dividends out of surplus, or if there is no surplus, out of net profits for the
fiscal year in which the dividend is declared and/or the preceding year. No
dividends may be declared, however, if the capital of TCF has been diminished by
depreciation, losses or otherwise to an amount less than the aggregate amount of
capital represented by any issued and outstanding stock having a preference on
distribution.
 
    If TCF were liquidated, the holders of Common Stock would be entitled to
receive, pro rata, all assets available for distribution to them after full
satisfaction of TCF's liabilities and any required payments applicable to the
preferred stock then outstanding.
 
    TRANSFER AGENT AND REGISTRAR.  The transfer agent and registrar for the
Common Stock is Boston EquiServe, Boston, Massachusetts.
 
    PREFERRED SHARE PURCHASE RIGHTS.  On May 23, 1989, the Board of Directors of
TCF declared a dividend of one Right for each outstanding share of Common Stock.
The dividend was paid on June 9, 1989 to the holders of record of Common Stock
on that date. Holders of shares of Common Stock issued subsequent to that date
receive one Right with each such share issued. The Rights are transferred with
and only with the shares of Common Stock until they become exercisable. The
Rights become exercisable only under certain circumstances described below. The
Rights are designed to ensure that holders of Common Stock receive fair and
equal treatment in the event of any proposed takeover of TCF and to discourage
certain abusive takeover techniques. They are also intended to enable holders of
Common Stock to realize the long-term value of their investment in TCF. While
not preventing a takeover, the Rights are designed to encourage any person
seeking to acquire TCF to negotiate with the Board of Directors of TCF. The
Rights may have the effect of discouraging, but are not intended to prevent,
takeover proposals.
 
    Until a Right is exercised, the holder thereof, as such, will have no rights
as a stockholder of TCF, including the right to vote or receive dividends. Upon
becoming exercisable, each Right entitles the
 
                                       10
<PAGE>
registered holder to purchase from TCF one one-hundredth of a share of Series A
Junior Participating Preferred Stock ("Series A Junior Preferred Stock") of TCF
at a price (the "Purchase Price") of $180 per one one-hundredth of a share of
Series A Junior Preferred Stock, subject to adjustment. The description and
terms of the Rights are set forth in a Rights Agreement (the "Rights Agreement")
between TCF and Boston EquiServe as rights agent. The Purchase Price payable,
and the number of shares of Series A Junior Preferred Stock or other securities
or property issuable, upon exercise of the Rights are subject to adjustment from
time to time to prevent dilution upon the occurrence of certain events specified
in the Rights Agreement.
 
    The Rights will become exercisable only if a person or group acquires or
announces an offer to acquire 15% or more of the outstanding shares of Common
Stock. The Rights have certain additional features that will be triggered upon
the occurrence of any one of certain specified events:
 
        (i) In the event that any person or group becomes the beneficial owner
    of 15% or more of the outstanding shares of Common Stock, subject to certain
    exceptions for shares owned by TCF, a subsidiary or an employee benefit plan
    or issued directly by TCF, proper provision shall be made so that each
    holder of a Right, other than any person or group beneficially owning 15% or
    more of the outstanding Common Stock (whose Rights will thereafter be void),
    will thereafter have the right to receive upon exercise that number of
    shares of Common Stock having a market value of two times the exercise price
    of the Right (or, at the option of TCF, an equivalent number of one
    one-hundredths of a share of Series A Junior Preferred Stock).
 
        (ii) In the event that TCF is acquired in a merger or other business
    combination transaction or 50% or more of its consolidated assets or
    earnings power is sold, proper provision will be made so that each holder of
    a Right will thereafter have the right to receive, upon the exercise thereof
    at the then-current exercise price of the Right, that number of shares of
    common stock of the acquiring company which at the time of such transaction
    will have a market value of two times the exercise price of the Right.
 
        (iii) At any time after the acquisition by a person or group of
    beneficial owners of 15% or more of the outstanding shares of Common Stock
    and prior to the acquisition by such person or group of 50% or more of the
    outstanding Common Stock, the Board of Directors of TCF may exchange the
    Rights (other than Rights owned by such person or group which have become
    void), in whole or in part, at an exchange ratio of one share of Common
    Stock, or one one-hundredth of a share of Series A Junior Preferred Stock
    (or of a share of a class or series of TCF's preferred stock having
    equivalent rights, preferences and privileges), per Right (subject to
    adjustment).
 
    At any time prior to the acquisition by a person or group of beneficial
ownership of 15% or more of the outstanding Common Stock, a majority of TCF's
directors prior to the time of such an acquisition may vote to redeem the Rights
in whole, but not in part, at a price of $.01 per right. The redemption of the
Rights may be made effective at such time on such basis and with such conditions
as such directors in their sole discretion may establish. Immediately upon any
redemption of the Rights, the right to exercise the Rights will terminate and
the only right of the holders of Rights will be to receive the redemption price.
 
    The terms of the Rights may be amended by the Board of Directors of TCF
without the consent of the holders of the Rights, including an amendment to
lower the 15% triggering thresholds described above to not less than the greater
of (i) any percentage greater than the largest percentage of the outstanding
Common Stock then known to TCF to be beneficially owned by any person or group
of affiliated or associated persons and (ii) 10%, except that from and after
such time as any person or group acquires 15% or more of the outstanding Common
Stock, no such amendment may adversely effect the interests of the holders of
the Rights.
 
    The Rights will expire on June 9, 1999, unless extended or earlier redeemed
by TCF.
 
                                       11

PREFERRED STOCK
 
    GENERAL.  Pursuant to the TCF Certificate of Incorporation, as amended,
there are authorized 30,000,000 shares of preferred stock, par value $.01 per
share, and the Board of Directors of TCF has the authority, without further
stockholder action, to issue from time to time one or more series of preferred
stock with such terms and for such consideration as the TCF Board of Directors
may determine. The TCF Board of Directors is authorized to fix the dividend
rights and terms, conversion rights, voting rights, redemption rights and terms,
liquidation preferences, sinking funds and any other rights, preferences,
privileges and restrictions applicable to each such series of preferred stock.
 
    The issuance of preferred stock, while providing flexibility in connection
with possible acquisitions and other corporate purposes, could, among other
things, adversely affect the voting power and other rights of the holders of
Common Stock and under certain circumstances have the effect of delaying or
preventing a change in control of TCF.
 
    SERIES A JUNIOR PREFERRED STOCK.  The Board of Directors of TCF has
established a series of preferred stock, designated Series A Junior Preferred
Stock, issuable upon the exercise of Rights issued to holders of the Common
Stock. As of April 30, 1997, there were currently 346,127 shares of Series A
Junior Preferred Stock reserved for issuance upon the exercise of the Rights.
Series A Junior Preferred Stock ranks junior to all other series of preferred
stock that might be created and is not redeemable. Each Series A Junior
Preferred Stock share is, subject to the rights of senior securities of TCF,
entitled to a minimum preferential quarterly dividend payment of $1.00 per
share, however, each such share is limited to an aggregate dividend of 100 times
the dividend declared per share of Common Stock. In the event of liquidation,
the holders of the Series A Junior Preferred Stock, upon issuance, are entitled
to a minimum preferential liquidation payment of $100 per share but such payment
is limited to an aggregate payment of 100 times the payment made per share of
Common Stock. Each Series A Junior Preferred Stock share, upon issuance, will
have 100 votes, voting together with the Common Stock. Finally, in the event of
any merger, consolidation or other transaction in which Common Stock is
exchanged, each Series A Junior Preferred Stock share will be entitled to
receive 100 times the amount received per share of Common Stock. These rights
are protected by customary antidilution provisions.
 
                              PLAN OF DISTRIBUTION
 
    The shares of Common Stock offered by the Company may be sold from time to
time to purchasers directly in one or more transactions at a fixed price, which
may be changed, at varying prices determined at the time of sale or at
negotiated prices. Alternatively, the Company may from time to time sell the
Common Stock in transactions involving broker-dealers who may act as agents
and/or may acquire Common Stock from the Company as principals and who may
receive compensation from the Company and/or the purchasers of the shares.
Broker-dealers who acquire Common Stock as principals may thereafter resell such
Common Stock in transactions, including transactions of the nature described
above. Broker-dealers may be entitled, under agreements that may be entered into
with the Company, to indemnification by the Company against certain liabilities,
including liabilities under the Securities Act. Any broker-dealers who
participate in a sale of shares of Common Stock may be deemed to be
"underwriters" as defined in the Securities Act. Any commissions paid or any
discounts or concessions allowed to any such broker-dealers, and, if any such
broker-dealers purchase shares of Common Stock as principals, any profits
received on the resale of such shares of Common Stock, may be deemed to be
underwriting discounts and commissions under the Securities Act.
 
    The rules of the Commission may prohibit underwriters, brokers, dealers and
certain other persons engaged or participating in the distribution of the Common
Stock from making a market in such Common Stock during a "cooling off" period
preceding the commencement of such distribution if TCF does not, at the time of
such distribution, meet certain minimum average daily trading volume and public
float tests.
 
                                       12
<PAGE>
    In order to comply with the securities laws of certain states, if
applicable, the Common Stock will be sold in such jurisdictions only through
registered or licensed brokers or dealers. In addition, in certain states the
Common Stock may not be sold unless it has been registered or qualified for sale
in the applicable state or an exemption from the registration or qualification
requirement is available and is complied with.
 
    The Company engaged Piper Jaffray Inc. ("Piper Jaffray") to act as its
financial advisor in connection with the Winthrop Merger pursuant to the terms
of an engagement letter (the "Winthrop Engagement Letter"). The Company engaged
Piper Jaffray to act as its financial advisor in connection with the Standard
Merger pursuant to the terms of an engagement letter (the "Standard Engagement
Letter"). Piper Jaffray may also provide assistance with respect to the sale of
all or a portion of the shares of Common Stock offered hereby. Such assistance
may consist of effecting sales of the shares of Common Stock offered hereby
through market making activities or in block trades at its usual and customary
commissions for such trades. Piper Jaffray currently has no obligation to take
or pay for any shares of Common Stock offered hereby. Any assistance by Piper
Jaffray with respect to the sale of the Common Stock offered hereby will be
provided pursuant to a separate agreement containing customary terms and
conditions, including indemnification provisions similar to those contained in
the Winthrop Engagement Letter and Standard Engagement Letters (collectively the
"Engagement Letters") described in the next paragraph. If Piper Jaffray provides
such assistance, it may thereby be subject to restrictions on market making
activities during any "cooling off" period described above.
 
    Pursuant to the Winthrop Engagement Letter, the fees payable to Piper
Jaffray in connection with the Winthrop Merger were $300,000. Pursuant to the
Standard Engagement Letter, the fees payable to Piper Jaffray in connection with
the Standard Merger were $300,000. In addition, TCF has agreed to reimburse
Piper Jaffray for its reasonable out-of-pocket expenses and to indemnify Piper
Jaffray against certain expenses and liabilities arising in connection with its
engagements, including liabilities under the Securities Act and the Exchange
Act. Piper Jaffray has from time to time issued research reports and
recommendations on the Common Stock and, in the ordinary course of business,
makes a market in the Common Stock. In the course of its market making and other
trading activities, Piper Jaffray may from time to time have a long or short
position in, and buy and sell, securities of TCF.
 
    There can be no assurance that the Company will sell any or all of the
shares of Common Stock offered hereby. It is anticipated that this Offering will
remain in effect until the shares of Common Stock offered hereby have been sold,
but in no event will any shares be sold in the Offering after the closing of the
Winthrop Merger.
 
                                 LEGAL OPINIONS
 
    The validity of the Common Stock offered hereby and certain other matters
will be passed upon for TCF by Kaplan, Strangis and Kaplan, P.A., Minneapolis,
Minnesota. Ralph Strangis, a director of TCF, is a member of Kaplan, Strangis
and Kaplan, P.A.
